In this study, we investigated whether juvenile Xenopus laevis could be used as an infection model for human pathogenic bacteria. Xenopus frogs succumbed to intraperitoneal injection containing the human pathogenic bacteria Staphylococcus aureus, Pseudomonas aeruginosa, and Listeria monocytogenes. In contrast, non-pathogenic bacteria Bacillus subtilis and Escherichia coli did not induce mortality in Xenopus frogs. The administration of appropriate antibiotics suppressed mortality caused by S. aureus and P. aeruginosa. Strains lacking the agr locus, cvfA (rny) gene, or hemolysin genes in S. aureus, LIPI-1-deleted mutant of L. monocytogenes, which attenuate virulence within mammals, exhibited reduced virulence in Xenopus frogs compared with their respective wild-type counterparts. Bacterial distribution analysis revealed that S. aureus persisted in the blood, liver, heart, and muscles of Xenopus frogs until death. These results suggested that intraperitoneal injection of human pathogenic bacteria induces sepsis-like symptoms in Xenopus frogs, supporting their use as a valuable animal model for evaluating antimicrobial efficacy and identifying virulence genes in various human pathogenic bacteria. en-copyright= kn-copyright= en-aut-name=KuriuAyano en-aut-sei=Kuriu en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshikawaKazuya en-aut-sei=Ishikawa en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsuchiyaKohsuke en-aut-sei=Tsuchiya en-aut-mei=Kohsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FurutaKazuyuki en-aut-sei=Furuta en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KaitoChikara en-aut-sei=Kaito en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Division of Molecular Biology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Division of Molecular Biology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Division of Immunology and Molecular Biology, Cancer Research Institute, Kanazawa University kn-affil= affil-num=4 en-affil=Division of Molecular Biology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Division of Molecular Biology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=animal infection model kn-keyword=animal infection model en-keyword=Staphylococcus aureus kn-keyword=Staphylococcus aureus en-keyword=Listeria monocytogenes kn-keyword=Listeria monocytogenes en-keyword=Pseudomonas aeruginosa kn-keyword=Pseudomonas aeruginosa en-keyword=antibiotics efficacy kn-keyword=antibiotics efficacy en-keyword=virulence genes kn-keyword=virulence genes en-keyword=hemolysin kn-keyword=hemolysin END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=6 article-no= start-page=97 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250411 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of aged garlic extract on experimental periodontitis in mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aged garlic extract (AGE) has been reported to exert anti?inflammatory effects. AGE has been recently found to reduce the inflammatory symptoms of periodontitis, a widespread chronic inflammatory disease caused by oral bacterial infection. However, the mechanisms underlying these effects remain unclear. In the present study, it was aimed to determine the effects of AGE on experimental periodontitis and the related inflammatory factors. AGE (2 g/kg/day) was orally administered to 15 mice during the experimental period, while a control group consisted of 15 mice that received pure water. A total of 3 days after initiation of administration, the left maxillary second molar was ligated with a 5?0 silk thread for 7 days. Blood biochemical tests were performed to monitor the systemic effects of AGE. Alveolar bone loss was measured morphometrically using a stereomicroscope, and reverse transcription?quantitative PCR was performed to assay mRNAs of proinflammatory cytokines in gingival tissues. A histological survey was also performed to identify osteoclasts in periodontitis lesions (five mice per group). The total protein and albumin levels showed no significant differences between the AGE and control groups. However, ligation?induced bone resorption was lower in the AGE group than in the control group (P=0.01). Additionally, ligature increased the mRNA expression of inflammatory cytokines, whereas AGE administration tended to suppress them. Remarkably, tumor necrosis factor gene expression was significantly suppressed (P=0.04). The number of osteoclasts in periodontitis lesions was reduced in the AGE?treated group. These results indicate that AGE prevents alveolar bone loss by suppressing the inflammatory responses related to osteoclast differentiation in the periodontal tissue. Further research is needed to elucidate the role of AGE in reducing inflammatory bone resorption. en-copyright= kn-copyright= en-aut-name=KuangCanyan en-aut-sei=Kuang en-aut-mei=Canyan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiraiAnna en-aut-sei=Hirai en-aut-mei=Anna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Kamei?ƒ«agataChiaki en-aut-sei=Kamei?ƒ«agata en-aut-mei=Chiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NangoHiroshi en-aut-sei=Nango en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OhtaniMasahiro en-aut-sei=Ohtani en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OmoriKazuhiro en-aut-sei=Omori en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Pathophysiology?Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Division of Periodontics and Endodontics, Department of Dentistry, Okayama University Hospital kn-affil= affil-num=3 en-affil=Division of Periodontics and Endodontics, Department of Dentistry, Okayama University Hospital kn-affil= affil-num=4 en-affil=Central Research Institute, Wakunaga Pharmaceutical Co., Ltd. kn-affil= affil-num=5 en-affil=Central Research Institute, Wakunaga Pharmaceutical Co., Ltd. kn-affil= affil-num=6 en-affil=Department of Pathophysiology?Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Pathophysiology?Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=AGE kn-keyword=AGE en-keyword=experimental periodontitis kn-keyword=experimental periodontitis en-keyword=bone resorption kn-keyword=bone resorption en-keyword=inflammation kn-keyword=inflammation en-keyword=osteoclasts kn-keyword=osteoclasts END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=1 article-no= start-page=36 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250416 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Anticoagulant effects of edoxaban in cancer and noncancer patients with venous thromboembolism en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Edoxaban, a direct oral anticoagulant (DOAC), is a first-line treatment for venous thromboembolism (VTE) and the suppression of VTE recurrence. In patients with cancer, however, recurrent VTE after DOAC treatment may be more common than in noncancer patients. To evaluate our hypothesis that the anticoagulation effect of edoxaban is lower in VTE patients with cancer than in noncancer patients.
Methods This study was a prospective, multicenter, observational study including patients treated with edoxaban for VTE in Japan. The primary outcome was the difference in the prothrombin time (PT), activated partial thromboplastin time (APTT), and D-dimer level at 5 h after initial edoxaban administration between the cancer and noncancer groups. An additional outcome was the longitudinal change in PT and APTT from 5 h to overnight after edoxaban administration. The incidence of adverse events was further investigated.
Results PT and APTT at 5 h after initial edoxaban administration were not significantly different between the cancer (n = 84) and noncancer groups (n = 138) (e.g., log-transformed APTT 3.55 vs. 3.55, p = 0.45). However, D-dimer in the cancer groups was significantly greater than that in the noncancer groups (log-transformed 1.83 vs. 1.79, p = 0.009). PT and APTT significantly decreased from 5 h to overnight after edoxaban, but a similar pattern was observed in each group. All adverse events after edoxaban administration were also similar between patients with cancer and noncancer.
Conclusion PT and APTT after edoxaban administration were similar between VTE patients with cancer and noncancer groups, suggesting that edoxaban has anticoagulation effects on cancer-associated VTE similar to those of noncancer patients.

kn-article= en-subject= kn-subject= en-title= kn-title=Surgical protocol of robotic liver resection using a two-surgeon technique (TAKUMI-3): a technical note and initial outcomes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Internationally, evidence supporting robotic liver resection (RLR) has gradually increased in recent years. However, a standardized protocol for RLR remains lacking. This study describes a surgical protocol and the initial outcomes of RLR in a high-volume center for robotic hepatopancreatobiliary surgery in Japan.
Methods Patients were placed in the reverse Trendelenburg position, with a supine position for anterolateral tumors and left lateral position for posterosuperior tumors. Our standard RLR protocol involved a two-surgeon technique. Liver parenchymal transection was performed by an assistant using the clamp crush technique with a console, with or without a laparoscopic Cavitron ultrasonic surgical aspirator (CUSA). Surgical techniques, including the tips, tricks, and pitfalls of RLR, are also demonstrated.
Results We performed 113 RLR at our institution for common primary diseases, including hepatocellular carcinoma (n = 52, 46.0%) and metastatic tumors (n = 48, 42.5%) between July 2022 and December 2024. The median operative time and estimated blood loss were 156 min (interquartile range [IQR], 121-209 min) and 20 mL (IQR, 0-100 mL), respectively. During liver parenchymal transection, a laparoscopic CUSA was used in 59 patients (52.2%), and a water-jet scalpel was used in 12 patients (10.6%). The incidence of mortality, major complications, and bile leakage was 0%, 6.2%, and 2.7%, respectively. The median hospital stay was 7 days (IQR, 6-9 days).
Conclusions We successfully introduced an RLR program using the two-surgeon technique. Safe implementation of RLR can be achieved upon completion of the training program and thorough understanding of the surgical protocols. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UmedaYuzo en-aut-sei=Umeda en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamadaMotohiko en-aut-sei=Yamada en-aut-mei=Motohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishiyamaTakeyoshi en-aut-sei=Nishiyama en-aut-mei=Takeyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NagaiYasuo en-aut-sei=Nagai en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KanehiraNoriyuki en-aut-sei=Kanehira en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Hepatobiliary Pancreatic Surgery, Ehime University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Liver resection kn-keyword=Liver resection en-keyword=Robotic surgery kn-keyword=Robotic surgery en-keyword=Training kn-keyword=Training en-keyword=Outcomes kn-keyword=Outcomes END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=2 article-no= start-page=156 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250411 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical-level screening of sleep apnea syndrome with single-lead ECG alone is achievable using machine learning with appropriate time windows en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose To establish a simple and noninvasive screening test for sleep apnea (SA) that imposes less burden on potential patients. The specific objective of this study was to verify the effectiveness of past and future single-lead electrocardiogram (ECG) data from SA occurrence sites in improving the estimation accuracy of SA and sleep apnea syndrome (SAS) using machine learning.
Methods The Apnea-ECG dataset comprising 70 ECG recordings was used to construct various machine-learning models. The time window size was adjusted based on the accuracy of SA detection, and the performance of SA detection and SAS diagnosis (apnea?hypopnea index???5 was considered SAS) was compared.
Results Using ECG data from a few minutes before and after the occurrence of SAs improved the estimation accuracy of SA and SAS in all machine learning models. The optimal range of the time window and achieved accuracy for SAS varied by model; however, the sensitivity ranged from 95.7 to 100%, and the specificity ranged from 91.7 to 100%.
Conclusions ECG data from a few minutes before and after SA occurrence were effective in SA detection and SAS diagnosis, confirming that SA is a continuous phenomenon and that SA affects heart function over a few minutes before and after SA occurrence. Screening tests for SAS, using data obtained from single-lead ECGs with appropriate past and future time windows, should be performed with clinical-level accuracy. en-copyright= kn-copyright= en-aut-name=YamaneTakahiro en-aut-sei=Yamane en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiiMasanori en-aut-sei=Fujii en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoritaMizuki en-aut-sei=Morita en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Biomedical Informatics, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Geriatric Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Biomedical Informatics, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Disease screening kn-keyword=Disease screening en-keyword=Sleep apnea syndrome (SAS) kn-keyword=Sleep apnea syndrome (SAS) en-keyword=Single-lead ECG kn-keyword=Single-lead ECG en-keyword=Artificial intelligence kn-keyword=Artificial intelligence en-keyword=Machine learning kn-keyword=Machine learning END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Enterobacterial common antigen repeat-unit flippase WzxE is required for Escherichia coli growth under acidic conditions, low temperature, and high osmotic stress conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Colanic acid and enterobacterial common antigen (ECA) are cell-surface polysaccharides that are produced by many Escherichia coli isolates. Colanic acid is induced under acidic, low temperature, and high-salt conditions and is important for E. coli resistance to these stresses; however, the role of ECA in these stresses is less clear. Here, we observed that knockout of flippase wzxE, which translocates lipid-linked ECA repeat units from the cytoplasmic side of the inner membrane to the periplasmic side, resulted in the sensitivity of E. coli BW25113 to acidic conditions. The wzxE-knockout mutant showed reduced growth potential and viable counts in vegetable extracts with acidic environments, including cherry tomatoes, carrots, celery, lettuce, and spinach. A double-knockout strain of wzxE and wecF (glycosyltransferase that adds the third-and-final sugar of the lipid-linked ECA repeat unit) was not sensitive to acidic conditions, with similar results obtained for a double-knockout strain of wzxE and wcaJ (glycosyltransferase that initiates colanic acid lipid-linked repeat-unit biosynthesis). The wzxE-knockout mutant was sensitive to low temperatures or high-salt conditions, which induced colanic acid synthesis, and these sensitivities were abolished by the additional knockout of wcaJ. These results suggest that lipid-linked ECA repeat units confer E. coli susceptibility to acidic, low temperatures, and high-salt conditions in a colanic acid-dependent manner and that wzxE suppresses this negative effect. en-copyright= kn-copyright= en-aut-name=YamaguchiSaki en-aut-sei=Yamaguchi en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshikawaKazuya en-aut-sei=Ishikawa en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FurutaKazuyuki en-aut-sei=Furuta en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KaitoChikara en-aut-sei=Kaito en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=wzxE flippase kn-keyword=wzxE flippase en-keyword=enterobacterial common antigen kn-keyword=enterobacterial common antigen en-keyword=low pH kn-keyword=low pH en-keyword=low temperature kn-keyword=low temperature en-keyword=hyperosmotic stress kn-keyword=hyperosmotic stress END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=7 article-no= start-page=2287 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250327 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparison of Midazolam and Diazepam for Sedation in Patients Undergoing Double-Balloon Endoscopic Retrograde Cholangiopancreatography: A Propensity Score-Matched Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: The sedation method used in double-balloon endoscopic retrograde cholangiopancreatography (DB-ERCP) varies across countries and between healthcare facilities. No previous studies have compared the effects of different benzodiazepines on sedation during endoscopic procedures. This study aimed to compare the effects of midazolam and diazepam sedation on DB-ERCP outcomes. Methods: This retrospective cohort study analyzed consecutive patients who underwent DB-ERCP between January 2017 and February 2024. A total of 203 patients who were sedated with diazepam (n = 94) or midazolam (n = 109) were analyzed. Propensity score matching was applied to adjust for baseline group differences. The primary outcome was the incidence of sedation-related adverse events (AEs). Secondary outcomes included inadequate sedation requiring additional sedatives and risk factors for sedation-related AEs. Results: Sedation-related AEs were more frequent with diazepam (28% [21/75]) than with midazolam (14% [11/75]; p = 0.046). Hypoxia occurred more frequently with diazepam (19% [14/75]) than with midazolam (5% [4/75]; p = 0.012). However, no significant differences were observed between the two groups for hypotension (p = 0.41) and bradycardia (p = 1.0). Poor sedation requiring other sedatives occurred significantly more often with diazepam (8% [6/75]) compared with midazolam sedation (0% [0/75], p = 0.012). Multivariate analysis identified diazepam sedation (odds ratio, 2.3; 95% confidence interval, 1.0-5.3; p = 0.048) as the sole risk factor for sedation-related AEs. Conclusions: Midazolam is safer and more effective than diazepam sedation in patients undergoing DB-ERCP. en-copyright= kn-copyright= en-aut-name=FujiiYuki en-aut-sei=Fujii en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UchidaDaisuke en-aut-sei=Uchida en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HoriguchiShigeru en-aut-sei=Horiguchi en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsutsumiKoichiro en-aut-sei=Tsutsumi en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=8 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= en-keyword=adverse events kn-keyword=adverse events en-keyword=balloon-assisted ERCP kn-keyword=balloon-assisted ERCP en-keyword=benzodiazepine kn-keyword=benzodiazepine en-keyword=sedation kn-keyword=sedation END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The association between objectively measured physical activity and home blood pressure: a population-based real-world data analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Few studies have examined the association of objectively measured habitual physical activity (PA) and sedentary behavior with out-of-office blood pressure (BP). We investigated the associations of objectively measured PA intensity time, sedentary time, and step count with at-home BP. Using accelerometer-recorded PA indices and self-measured BP in 368 participants (mean age, 53.8 years; 58.7% women), we analyzed 115,575 records of each parameter between May 2019 and April 2024. PA intensities were categorized as light (2.0?2.9 metabolic equivalents [METs]); moderate (3.0?5.9 METs); vigorous (?6.0 METs), or sedentary (<2.0 METs): the median [interquartile ranges] for these variables was 188 [146?232], 83 [59?114], 1 [0?2], 501 [428?579] minutes, respectively, and for step count, was 6040 [4164?8457]. Means [standard deviations] for systolic and diastolic BP were 116.4 [14.2] and 75.2 [9.3] mmHg, respectively. A mixed-effect model adjusted for possible confounders showed that 1-h longer in vigorous PA was associated with lower systolic and diastolic BP (?1.69 and ?1.09?mmHg, respectively). A 1000-step increase in step count was associated with lower systolic and diastolic BP (?0.05 and ?0.02?mmHg, respectively). Associations were more pronounced among men and participants aged <60 years. Sedentary time was positively associated with BP in men and participants aged <60 years, but inversely associated with BP in women and participants aged ?60 years. Our findings suggest that more PA and less sedentary behavior were associated with BP reduction, particularly among men and participants aged <60 years. However, the clinical relevance of this effect remains uncertain because of its modest magnitude. en-copyright= kn-copyright= en-aut-name=KinutaMinako en-aut-sei=Kinuta en-aut-mei=Minako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HisamatsuTakashi en-aut-sei=Hisamatsu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TaniguchiKaori en-aut-sei=Taniguchi en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukudaMari en-aut-sei=Fukuda en-aut-mei=Mari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakahataNoriko en-aut-sei=Nakahata en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KandaHideyuki en-aut-sei=Kanda en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Environmental Medicine and Public Health, Izumo, Shimane University Faculty of Medicine kn-affil= affil-num=4 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Health and Nutrition, The University of Shimane Faculty of Nursing and Nutrition kn-affil= affil-num=6 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=37 cd-vols= no-issue=1 article-no= start-page=16 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The preoperative flexion tear gap affects postoperative meniscus stability after pullout repair for medial meniscus posterior root tear en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background We investigated whether the preoperative flexion tear gap (FTG) observed in open magnetic resonance imaging (MRI) affects meniscus stability after medial meniscus (MM) posterior root (MMPR) repairs. Furthermore, time-correlated MRI findings from MMPR tear occurrence were evaluated.
Methods This retrospective observational study included 54 patients (mean age, 64.6 years; 13 males and 41 females) who underwent pullout repair for radial degenerative MMPR tear. Meniscus stability (scored 0-4 points) was assessed using a semi-quantitative arthroscopic scoring system during second-look arthroscopy 1 year postoperatively. The FTG was evaluated on preoperative axial MRI at 90 degrees knee flexion. Other MRI measurements included MM extrusion (MME) at 10 degrees knee flexion, MM posterior extrusion (MMPE) at 90 degrees knee flexion, and MM posteromedial extrusion (MMpmE) at 90 degrees knee flexion preoperatively and 1 year postoperatively. The correlation between the arthroscopic stability score and MRI findings was investigated. A receiver-operating characteristic curve was calculated to predict a good meniscus healing score (3-4 points). The correlation between the FTG and patient demographics, including time from injury to MRI, was analyzed.
Results At 1 year postoperatively, MME increased by 1.1 mm, while MMpmE and MMPE decreased by 0.4 mm and 1.0 mm, respectively. The meniscus stability score was negatively correlated with the preoperative FTG (r = -0.61, p < 0.01). The time from injury to MRI was significantly correlated with the preoperative FTG. The receiver-operating characteristic curve identified an FTG cut-off value of 8.7 mm for predicting good postoperative stability, with sensitivity and specificity of 67% and 85%, respectively.
Conclusions FTG evaluated with open MRI at 90 degrees knee flexion was associated with time from injury and affected meniscus stability following pullout repair. MMPR tears should be treated in the early phase to increase meniscus healing stability. en-copyright= kn-copyright= en-aut-name=TamuraMasanori en-aut-sei=Tamura en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KitayamaTakahiro en-aut-sei=Kitayama en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YokoyamaYusuke en-aut-sei=Yokoyama en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KawadaKoki en-aut-sei=Kawada en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Medial meniscus kn-keyword=Medial meniscus en-keyword=Posterior root tear kn-keyword=Posterior root tear en-keyword=Distance kn-keyword=Distance en-keyword=Pullout repair kn-keyword=Pullout repair en-keyword=Second-look arthroscopy kn-keyword=Second-look arthroscopy END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=3 article-no= start-page=e0320482 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Serum uric acid level is associated with renal arteriolar hyalinosis and predicts post-donation renal function in living kidney donors en-subtitle= kn-subtitle= en-abstract= kn-abstract=Major guidelines for living-donor kidney transplantation underscore the need for pre-donation evaluation of renal function, hypertension, obesity, diabetes mellitus, and albuminuria to minimize the risk of donation from marginal donors. However, validity is yet to be established. We retrospectively investigated the relationship between clinical characteristics and histological indices in baseline renal biopsies (0-h biopsies) and whether these parameters could predict renal function in living kidney donors one year post-donation. Seventy-six living kidney donors were recruited for this study. In histological analyses, glomerulosclerosis, arteriosclerosis, arteriolosclerosis, arteriolar hyalinosis, and interstitial fibrosis and tubular atrophy scores/indices were evaluated. Post-donation serum creatinine levels in kidney donors with arteriolar hyalinosis were significantly higher than those in individuals without arteriolar hyalinosis. There was a significant correlation between baseline serum uric acid levels and the arteriolar hyalinosis index, with baseline uric acid level identified as an independent factor for hyalinosis in multiple regression analysis. Additionally, the serum uric acid level was a significant prognostic factor for post-donation serum creatinine after adjustment for baseline clinical parameters. These data demonstrate that pre-donation serum uric acid levels are associated with arteriolar hyalinosis in the kidney and could predict a decline in renal function during the first year after donation in living kidney donors. en-copyright= kn-copyright= en-aut-name=KanoYuzuki en-aut-sei=Kano en-aut-mei=Yuzuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanabeKatsuyuki en-aut-sei=Tanabe en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KitagawaMasashi en-aut-sei=Kitagawa en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SugiyamaHitoshi en-aut-sei=Sugiyama en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamanoiTomoaki en-aut-sei=Yamanoi en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshinagaKasumi en-aut-sei=Yoshinaga en-aut-mei=Kasumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=BekkuKensuke en-aut-sei=Bekku en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishimuraShingo en-aut-sei=Nishimura en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ArakiMotoo en-aut-sei=Araki en-aut-mei=Motoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Medicine, Kawasaki Medical School General Medical Center and Department of Medical Care Work, Kawasaki College of Health Professions kn-affil= affil-num=5 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue=1 article-no= start-page=101 end-page=131 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The characterizations of an alternating sign matrices using a triplet en-subtitle= kn-subtitle= en-abstract= kn-abstract=An alternating sign matrix (ASM for short) is a square matrix which consists of 0, 1 and ?1.

Trigger point injections (TPIs) serve as both a diagnostic and therapeutic tool. Although neurectomy is frequently chosen for patients with severe ACNES, its surgical outcomes remain unclear.
Aim: This study aims to evaluate both the short- and long-term outcomes for neurectomy and propose a novel therapeutic algorithm.
Methods: A cohort of postoperative patients presenting with ACNES between 2016 and 2023 was retrospectively evaluated. Patients received a single diagnostic TPI. When the pain subsided, an anterior neurectomy was performed using either an anterior or laparoscopic approach. Pain scores were assessed using the numeric rating scale (NRS).
Results: Among 37 patients (60% females, mean age 33.8?}?3.4?years), 29 patients (78.4%) experienced pain recurrence following initial neurectomy. Of these, 22 patients underwent repeat neurectomies, resulting in complete remission in 15 patients and no benefit in 7 patients. Long-term outcomes showed that 62.2% achieved clinical remission (NRS?=?0), whereas 8.1% reported reduced but persistent pain (NRS 1?2). Preoperative TPI effectiveness was a strong predictor of surgical success, with patients achieving post-TPI NRS (0?1) significantly more likely to attain remission (p?=?0.0074). Older age was also associated with higher remission rates (p?=?0.0476).
Conclusion: TPI is critical for predicting neurectomy success. These findings support the integration of preoperative TPI evaluation and tailored surgical strategies to optimize outcomes for patients with ACNES. en-copyright= kn-copyright= en-aut-name=KondoYoshitaka en-aut-sei=Kondo en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KanayaNobuhiko en-aut-sei=Kanaya en-aut-mei=Nobuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KobayashiAmi en-aut-sei=Kobayashi en-aut-mei=Ami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ArakawaKyosuke en-aut-sei=Arakawa en-aut-mei=Kyosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsuokaYoshikazu en-aut-sei=Matsuoka en-aut-mei=Yoshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MimataYudai en-aut-sei=Mimata en-aut-mei=Yudai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KakiuchiYoshihiko en-aut-sei=Kakiuchi en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShigeyasuKunitoshi en-aut-sei=Shigeyasu en-aut-mei=Kunitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KurodaShinji en-aut-sei=Kuroda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KagawaShunsuke en-aut-sei=Kagawa en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurology, Brigham and Women's Hospital, Harvard Medical School kn-affil= affil-num=4 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=anterior cutaneous nerve entrapment syndrome (ACNES) kn-keyword=anterior cutaneous nerve entrapment syndrome (ACNES) en-keyword=neurectomy kn-keyword=neurectomy en-keyword=trigger point injections (TPIs) kn-keyword=trigger point injections (TPIs) END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=4 article-no= start-page=252 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250305 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characteristics of oral mucositis in patients undergoing haploidentical stem cell transplantation with posttransplant cyclophosphamide: marked difference between busulfan and melphalan regimens en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose This study was performed to examine the effects of conditioning regimens on oral mucositis in haploidentical (haplo) donor hematopoietic stem cell transplantation (HSCT) with posttransplant cyclophosphamide (PTCy).

The fly can pollinate at lower and higher temperatures than European honeybee. However, management of the longevity of pollinators is important for growers using greenhouses. Previous studies using other insects showed that caffeine affects insect longevity and behaviors. For instance, European honeybee live longer and have increased memory after caffeine consumption. How caffeine affects the longevity and behavior of pollinators is worth investigating because it can affect pollinatorfs behavior, extend longevity, or be an insecticide against pollinators. In the present study, therefore, the longevity and locomotion of L. sericata were investigated when they were given different caffeine concentrations. First, the longevity of L. sericata with five different caffeine concentrations was compared to the control. The results showed that higher concentrations of caffeine (2%, 1%, and 0.5%) significantly decreased the life span compared to lower concentrations (0.05% and 0.01%). Second, the locomotion activities of L. sericata were examined at those two caffeine concentrations with treated and control male and female flies utilizing a Drosophila Activity Monitor (DAM). Treatment with 0.05% caffeine dramatically reduced locomotion, but treatment of 0.01% caffeine did not. We also compared lipid concentrations of flies: flies treated with 0.05% caffeine had a lower lipid concentration compared to flies treated with 0% and 0.01% caffeine. These results indicate that caffeine had negative effects on the longevity and locomotion activities of the pollinator L. sericata in laboratory conditions. en-copyright= kn-copyright= en-aut-name=NaingShine Shane en-aut-sei=Naing en-aut-mei=Shine Shane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiokaHaruna en-aut-sei=Fujioka en-aut-mei=Haruna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuuraTeruhisa en-aut-sei=Matsuura en-aut-mei=Teruhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Caffeine kn-keyword=Caffeine en-keyword=Life span kn-keyword=Life span en-keyword=Locomotor activity kn-keyword=Locomotor activity en-keyword=Pollinator kn-keyword=Pollinator END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue= article-no= start-page=103026 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The antimalarial activity of transdermal N-89 mediated by inhibiting ERC gene expression in P. Berghei-infected mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Through studies of new antimalarial drugs, we identified 1,2,6,7-tetraoxaspiro[7.11]nonadecane (N-89) as a potential drug candidate. Here, we analyzed the antimalarial action of a transdermal formulation (td) of N-89, designed for easy use by children, using Plasmodium berghei-infected mice as a model for malaria patients. The td N-89 or artemisinin (ART) formulation was transdermally administered to P. berghei-infected mice with 0.2?0.4 % parasitemia, twice daily for four days, at an effective dose of 90 % for malaria. Parasitemia was decreased in td N-89 and td ART groups during the drug treatment; then, three of the eight mice in td N-89 group were completely cured without relapse. Additionally, abnormal trophozoites in td N-89 group were observed 8 h after administration and increased up to 24 h. To study the change in endoplasmic reticulum-resident calcium-binding protein (ERC) gene expression with td N-89, we investigated the gene expression of P. berghei ERC (PbERC) after td N-89 treatment. PbERC gene expression was increased time-dependently in control group, and was statistically decreased at 4 and 8 h and then increased similar to that of control group at 12 h in td ART group. In contrast, the expression in td N-89 group was almost steady starting from 0 h. We also studied parasite egress-related genes expression after td N-89 treatment, plasmepsin X, subtilisin-like protease 1 and merozoite surface protein 1, were suppressed at 12 h compared to control group. These results suggest that N-89 affects function of endoplasmic reticulum via regulating gene suppression and subsequently parasite growth is inhibited. en-copyright= kn-copyright= en-aut-name=MatsumoriHiroaki en-aut-sei=Matsumori en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DinhThi Quyen en-aut-sei=Dinh en-aut-mei=Thi Quyen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoritaMasayuki en-aut-sei=Morita en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimHye-Sook en-aut-sei=Kim en-aut-mei=Hye-Sook kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Division of International Infectious Diseases Control, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Division of International Infectious Diseases Control, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Research Center for Intestinal Health Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Anatomy, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Division of International Infectious Diseases Control, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Synthetic antimalarial endoperoxide kn-keyword=Synthetic antimalarial endoperoxide en-keyword=Transdermal N-89 kn-keyword=Transdermal N-89 en-keyword=Artemisinin kn-keyword=Artemisinin en-keyword=In vivo kn-keyword=In vivo en-keyword=Abnormal trophozoite kn-keyword=Abnormal trophozoite en-keyword=Endoplasmic reticulum-resident calcium-binding protein (ERC) kn-keyword=Endoplasmic reticulum-resident calcium-binding protein (ERC) en-keyword=Parasite egress-related gene kn-keyword=Parasite egress-related gene END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=12 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Voice analysis and deep learning for detecting mental disorders in pregnant women: a cross-sectional study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction Perinatal mental disorders are prevalent, affecting 10-20% of pregnant women, and can negatively impact both maternal and neonatal outcomes. Traditional screening tools, such as the Edinburgh Postnatal Depression Scale (EPDS), present limitations due to subjectivity and time constraints in clinical settings. Recent advances in voice analysis and machine learning have shown potential for providing more objective screening methods. This study aimed to develop a deep learning model that analyzes the voices of pregnant women to screen for mental disorders, thereby offering an alternative to the traditional tools.
Methods A cross-sectional study was conducted among 204 pregnant women, from whom voice samples were collected during their one-month postpartum checkup. The audio data were preprocessed into 5000 ms intervals, converted into mel-spectrograms, and augmented using TrivialAugment and context-rich minority oversampling. The EfficientFormer V2-L model, pretrained on ImageNet, was employed with transfer learning for classification. The hyperparameters were optimized using Optuna, and an ensemble learning approach was used for the final predictions. The model's performance was compared to that of the EPDS in terms of sensitivity, specificity, and other diagnostic metrics.
Results Of the 172 participants analyzed (149 without mental disorders and 23 with mental disorders), the voice-based model demonstrated a sensitivity of 1.00 and a recall of 0.82, outperforming the EPDS in these areas. However, the EPDS exhibited higher specificity (0.97) and precision (0.84). No significant difference was observed in the area under the receiver operating characteristic curve between the two methods (p = 0.759).
Discussion The voice-based model showed higher sensitivity and recall, suggesting that it may be more effective in identifying at-risk individuals than the EPDS. Machine learning and voice analysis are promising objective screening methods for mental disorders during pregnancy, potentially improving early detection.
Conclusion We developed a lightweight machine learning model to analyze pregnant women's voices for screening various mental disorders, achieving high sensitivity and demonstrating the potential of voice analysis as an effective and objective tool in perinatal mental health care. en-copyright= kn-copyright= en-aut-name=OobaHikaru en-aut-sei=Ooba en-aut-mei=Hikaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MakiJota en-aut-sei=Maki en-aut-mei=Jota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Perinatal mental disorders kn-keyword=Perinatal mental disorders en-keyword=Voice analysis kn-keyword=Voice analysis en-keyword=Machine learning kn-keyword=Machine learning en-keyword=Screening kn-keyword=Screening en-keyword=Pregnant women kn-keyword=Pregnant women END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=3267 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250125 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Novel treatment strategy targeting interleukin-6 induced by cancer associated fibroblasts for peritoneal metastasis of gastric cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cancer-associated fibroblasts (CAFs) are a crucial component in the tumor microenvironment (TME) of peritoneal metastasis (PM), where they contribute to tumor progression and metastasis via secretion of interleukin-6 (IL-6). Here, we investigated the role of IL-6 in PM of gastric cancer (GC) and assessed whether anti-IL-6 receptor antibody (anti-IL-6R Ab) could inhibit PM of GC. We conducted immunohistochemical analysis of IL-6 and alpha-smooth muscle (alpha-SMA) expressions in clinical samples of GC and PM, and investigated the interactions between CAFs and GC cells in vitro. Anti-tumor effects of anti-IL-6R Ab on PM of GC were investigated in an orthotopic murine PM model. IL-6 expression was significantly correlated with alpha-SMA expression in clinical samples of GC, and higher IL-6 expression in the primary tumor was associated with poor prognosis of GC. Higher IL-6 and alpha-SMA expressions were also observed in PM of GC. In vitro, differentiation of fibroblasts into CAFs and chemoresistance were observed in GC cells cocultured with fibroblasts. Anti-IL-6R Ab inhibited the progression of PM in GC cells cocultured with fibroblasts in the orthotopic mouse model but could not inhibit the progression of PM consisting of GC cells alone. IL-6 expression in the TME was associated with poor prognosis of GC, and CAFs were associated with establishment and progression of PM via IL-6. Anti-IL-6R Ab could inhibit PM of GC by the blockade of IL-6 secreted by CAFs, which suggests its therapeutic potential for PM of GC. en-copyright= kn-copyright= en-aut-name=MitsuiEma en-aut-sei=Mitsui en-aut-mei=Ema kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KikuchiSatoru en-aut-sei=Kikuchi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkuraTomohiro en-aut-sei=Okura en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TazawaHiroshi en-aut-sei=Tazawa en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UneYuta en-aut-sei=Une en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishiwakiNoriyuki en-aut-sei=Nishiwaki en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KurodaShinji en-aut-sei=Kuroda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KagawaShunsuke en-aut-sei=Kagawa en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OhtsukaJunko en-aut-sei=Ohtsuka en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OhkiRieko en-aut-sei=Ohki en-aut-mei=Rieko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Laboratory of Fundamental Oncology, National Cancer Center Research Institute kn-affil= affil-num=12 en-affil=Laboratory of Fundamental Oncology, National Cancer Center Research Institute kn-affil= affil-num=13 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Peritoneal metastasis kn-keyword=Peritoneal metastasis en-keyword=Gastric cancer kn-keyword=Gastric cancer en-keyword=Interleukin-6 kn-keyword=Interleukin-6 en-keyword=Cancer-associated fibroblasts kn-keyword=Cancer-associated fibroblasts en-keyword=Interleukin-6 receptor antibody kn-keyword=Interleukin-6 receptor antibody END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=2577 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Plasma S100A8/A9 level predicts response to immune checkpoint inhibitors in patients with advanced non-small cell lung cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Blood-based predictive markers for the efficacy of immune checkpoint inhibitors (ICIs) have not yet been established. We investigated the association of the plasma level of S100A8/A9 with the efficacy of immunotherapy. We evaluated patients with unresectable stage III/IV or recurrent non-small cell lung cancer (NSCLC) who were treated with ICIs at Okayama University Hospital. The pre-treatment plasma levels of S100A8/A9 were analyzed. Eighty-one eligible patients were included (median age, 69 years). Sixty-two patients were men, 54 had adenocarcinoma, 74 had performance status (PS) 0?1, and 47 received ICIs as first-line treatment. The median time to treatment failure (TTF) for ICIs was 5.7 months, and the median overall survival (OS) was 19.6 months. The TTF and OS were worse in patients with high plasma S100A8/A9 levels (??2.475 ?g/mL) (median TTF: 4.3 vs. 8.5 months, p?=?0.009; median OS: 15.4 vs. 38.0 months, p?=?0.001). Multivariate analysis revealed that PS???2, liver metastasis, and high plasma S100A8/A9 levels were significantly associated with short TTF and OS. In conclusion, plasma S100A8/A9 level may have a limited effect on ICI therapy for NSCLC. en-copyright= kn-copyright= en-aut-name=KuribayashiTadahiro en-aut-sei=Kuribayashi en-aut-mei=Tadahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KinoshitaRie en-aut-sei=Kinoshita en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NinomiyaKiichiro en-aut-sei=Ninomiya en-aut-mei=Kiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MakimotoGo en-aut-sei=Makimoto en-aut-mei=Go kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KuboToshio en-aut-sei=Kubo en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=RaiKammei en-aut-sei=Rai en-aut-mei=Kammei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IchiharaEiki en-aut-sei=Ichihara en-aut-mei=Eiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HottaKatsuyuki en-aut-sei=Hotta en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TabataMasahiro en-aut-sei=Tabata en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KiuraKatsuyuki en-aut-sei=Kiura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=SakaguchiMasakiyo en-aut-sei=Sakaguchi en-aut-mei=Masakiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=OhashiKadoaki en-aut-sei=Ohashi en-aut-mei=Kadoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Center for Clinical Oncology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= en-keyword=S100A8/A9 kn-keyword=S100A8/A9 en-keyword=Lung cancer kn-keyword=Lung cancer en-keyword=Immune checkpoint inhibitors kn-keyword=Immune checkpoint inhibitors END start-ver=1.4 cd-journal=joma no-vol=42 cd-vols= no-issue=6 article-no= start-page=529 end-page=537 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240809 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Adverse Events after Different Endoscopic Resection Procedures for Small and Intermediate-Sized Colorectal Polyps en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Cold snare polypectomy (CSP) and underwater endoscopic mucosal resection (UEMR) have been developed recently, in addition to conventional methods, but adverse events of each method have not been fully clarified. We compared the outcomes of each method for the appropriate choice. Methods: Patients who underwent CSP, endoscopic mucosal resection (EMR)/hot snare polypectomy (HSP), or UEMR for small and intermediate-sized colorectal polyps between April 2017 and June 2020 were retrospectively examined. The rate of adverse events and recurrences due to each method were determined as the main outcomes. Clinical factors related to adverse events were examined. Results: A total of 1,025 patients with 3,163 polyps underwent polypectomy using any of the methods. CSP, EMR/HSP, and UEMR were performed for 704 (22.2%), 2,145 (67.8%), and 314 polyps (9.9%), and the median size for each method was 4, 6, and 7 mm, respectively. Delayed bleeding for CSP, EMR/HSP, and UEMR was 0%, 0.2%, and 0.6% (p = 0.15), and perforation was 0%, 0.1%, and 0%, respectively (p = 0.62). Recurrence after CSP, EMR/HSP, and UEMR was 0.3%, 0.09%, and 1.3%, respectively (p < 0.01). Recurrence for UEMR was significantly higher in the early stage of procedure introduction (p = 0.015). Oral anticoagulants were the risk factor for delayed bleeding (p < 0.01, respectively). Conclusion: There was no significant difference regarding adverse events among each method for small and intermediate-sized polyps, although the recurrence rate after UEMR was higher than other methods. en-copyright= kn-copyright= en-aut-name=ToyosawaJunki en-aut-sei=Toyosawa en-aut-mei=Junki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamasakiYasushi en-aut-sei=Yamasaki en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AoyamaYuki en-aut-sei=Aoyama en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakeiKensuke en-aut-sei=Takei en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IgawaShoko en-aut-sei=Igawa en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=InokuchiToshihiro en-aut-sei=Inokuchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KinugasaHideaki en-aut-sei=Kinugasa en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakaharaMasahiro en-aut-sei=Takahara en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Internal Medicine, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=11 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= en-keyword=Underwater endoscopic mucosal resection kn-keyword=Underwater endoscopic mucosal resection en-keyword=Endoscopic mucosal resection kn-keyword=Endoscopic mucosal resection en-keyword=Cold snare polypectomy kn-keyword=Cold snare polypectomy END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=04 article-no= start-page=E351 end-page=E357 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230213 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Degree of pharyngeal deformation caused by pharyngeal endoscopic submucosal dissection is associated with the incidence of aspiration pneumonia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and study aims?Endoscopic submucosal dissection (ESD) is one of the most minimally invasive treatments for superficial squamous cell cancer of the pharynx. However, aspiration pneumonia (AsP) associated with postoperative deformity of the pharynx may occur. The purpose of this study was to investigate the frequency of AsP and the degree of pharyngeal deformity after pharyngeal ESD.
Patients and methods?This was a retrospective observational study of patients who underwent pharyngeal ESD at Okayama University Hospital between 2006 and 2017.?The degree of pharyngeal deformation was assessed using the pharyngeal deformation grade (PDG). The primary endpoint was the frequency of AsP as a long-term adverse event.
Results?Among the 52 patients enrolled, nine developed aspiration pneumonia, with a 3-year cumulative incidence of 9.0?% (95?% confidence interval [CI], 3.3?%?22.0?%). There were 16, 18, 16, and two patients that had PDG 0, 1, 2, and 3, respectively. Patients with a history of radiotherapy, as a treatment of head and neck cancer (44.4?% vs. 11.6?%; P?=?0.02) and the high PDG group (PDG 2 and 3) (77.8?% vs. 25.6?%; P?=?0.005) had a significantly higher incidence of AsP. The 3-year cumulative incidence rate of AsP after ESD in the high PDG group was significantly higher than that in the low PDG group (PDG 0 and 1) (23.9?% [95?%CI, 9.2.?49.5%] vs. 0?%; P?=?0.03).
Conclusions?The incidence of aspiration pneumonia in the long-term course after pharyngeal ESD was revealed. The incidence of aspiration pneumonia may be associated with pharyngeal deformity, but further studies are needed. en-copyright= kn-copyright= en-aut-name=AbeMakoto en-aut-sei=Abe en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawaharaYoshiro en-aut-sei=Kawahara en-aut-mei=Yoshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ObayashiYuka en-aut-sei=Obayashi en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BabaYuki en-aut-sei=Baba en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HamadaKenta en-aut-sei=Hamada en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakaeHiroyuki en-aut-sei=Sakae en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KonoYoshiyasu en-aut-sei=Kono en-aut-mei=Yoshiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KanzakiHiromitu en-aut-sei=Kanzaki en-aut-mei=Hiromitu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MakinoTakuma en-aut-sei=Makino en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NodaYohei en-aut-sei=Noda en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MarunakaHidenori en-aut-sei=Marunaka en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241214 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of aged microplastics on paddy soil properties and greenhouse gas emissions under laboratory aerobic conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Microplastics (MPs) formed after changes in chemical or physical properties may alter soil properties, which in turn may affect microbial activities and greenhouse gas (GHG) emissions. However, few studies have focused on the effects of aged MPs changes on soil properties and greenhouse gas emissions. Therefore, we aimed to investigate the impact of MPs with different aging times on soil GHG emissions and dissolved organic carbon (DOC). Low-density polyethylene (PE) and polylactic acid (PLA) were treated with ultraviolet (UV) irradiation for 0?2?weeks. Soil was incubated with PE or PLA 1% (w/w) concentration at 60% water holding capacity (WHC) for 35?days. Emissions of nitrous oxide (N2O) and carbon dioxide (CO2) were measured on days 0, 1, 3, 5, 7, 14, 21, 28, and 35. Results showed that CO2 and N2O emissions were higher (p? Method: The authors examined the chapters on emergency medicine in the RHCPs of 47 prefectural governments for the overall structure, cost-benefits, and connection to community-based integrated care systems. The type and number of clinical measures listed as numerical metrics and their classification methods were emphasized.
Result: Regarding the overall plan structure, 40 prefectural governments began their description with an analysis of current surroundings. In total, 24 prefectural governments mentioned community-based integrated care systems but none mentioned cost-benefit analysis. Altogether, only 43 of 47 prefectural governments (91%) indicated numerical metrics. The maximum number of numerical targets for quality measures by prefecture was 19, the minimum was 0, and the median was 4 (IQR: 3-6.5); there were 220 metrics in total, with 82 structural, 96 process, and 42 outcome measures. Additionally, 13 prefectures (28%) classified quality measures according to the MHLWfs guidance, 6 (13%) used their own classification manner, while the others did not classify their measures.
Conclusions: There were significant differences in emergency medicine policies and quality metrics among the prefectural governments. Further research is needed to develop and establish more comprehensive and appropriate metrics based on a common methodology to improve the quality of emergency medicine. en-copyright= kn-copyright= en-aut-name=IidaAtsuyoshi en-aut-sei=Iida en-aut-mei=Atsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoShinya en-aut-sei=Saito en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamadaJun en-aut-sei=Hamada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakamuraShunsuke en-aut-sei=Nakamura en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MikaneTakeshi en-aut-sei=Mikane en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Graduate School of Health Sciences, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Health and Welfare Services Management, Kawasaki University of Medical Welfare kn-affil= affil-num=4 en-affil=Department of Emergency Medicine, Japanese Red Cross Okayama Hospital kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Emergency Medicine, Japanese Red Cross Okayama Hospital kn-affil= en-keyword=emergency medicine kn-keyword=emergency medicine en-keyword=indicator kn-keyword=indicator en-keyword=measure kn-keyword=measure en-keyword=quality assurance kn-keyword=quality assurance en-keyword=quality improvement kn-keyword=quality improvement END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=3 article-no= start-page=e20220127 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=2023 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Rapid thawing of frozen bull spermatozoa by transient exposure to 70 ‹C improves the viability, motility and mitochondrial health en-subtitle= kn-subtitle= en-abstract= kn-abstract=Up to now, the definitive conclusion of the positive effects of rapid transient thawing at higher temperatures for shorter durations has not been obtained yet and is still under discussion due to some contradictory findings and limited assessment of post-thawed parameters. The purpose of the current study was to evaluate the effectiveness of rapid thawing in water at 70 ‹C by using various post-thawed parameters of frozen bull spermatozoa. Experiment 1, monitoring the change of temperature inside frozen bull straw thawed in water at different temperatures. Experiment 2, evaluation of various post-thawed characteristics of frozen bull spermatozoa thawed in water at different temperatures by using a computer-assisted sperm analysis, flow cytometry and immunocytochemistry. The time it took for the temperature inside the straw to warm up to 15 ‹C was nearly twice as faster when the straw was thawed in 70 ‹C water compared with 39 ‹C. Although there were differences among bulls, viability, motility, and mitochondrial membrane potential of spermatozoa thawed at 70 ‹C for 8 seconds and stabilized at 39 ‹C for 52 seconds were significantly higher than those of controls (thawed at 39 ‹C for 60 seconds) at 0 and 3 h after thawing. Just after thawing, however, there were no differences in acrosome integrity and distribution of phospholipase C zeta1, whereas mitochondrial reactive oxygen species production was significantly lower in spermatozoa thawed at 70 ‹C. From these results, we conclude that rapid thawing at 70 ‹C and then stabilization at 39 ‹C significantly improves viability, motility and mitochondrial health of bull spermatozoa rather than conventional thawing at 39 ‹C. The beneficial effect of rapid transient thawing could be due to shorter exposure to temperatures outside the physiological range, consequently maintaining mitochondrial health. en-copyright= kn-copyright= en-aut-name=NguyenHai Thanh en-aut-sei=Nguyen en-aut-mei=Hai Thanh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DoSon Quang en-aut-sei=Do en-aut-mei=Son Quang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AthurupanaRukmali en-aut-sei=Athurupana en-aut-mei=Rukmali kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WakaiTakuya en-aut-sei=Wakai en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FunahashiHiroaki en-aut-sei=Funahashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=bull semen kn-keyword=bull semen en-keyword=cryopreservation process kn-keyword=cryopreservation process en-keyword=phospholipase C zeta1 (PLCZ1) kn-keyword=phospholipase C zeta1 (PLCZ1) en-keyword=temperature of thawing kn-keyword=temperature of thawing END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=366 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The required experience of open pancreaticoduodenectomy before becoming a specialist in hepatobiliary and pancreatic surgeons: a multicenter, cohort study of 334 open pancreaticoduodenectomies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Open pancreaticoduodenectomy (OPD) is an essential surgical procedure for expert hepato-biliary-pancreatic (HBP) surgeons. However, there is no standard for how many surgeries must be performed by a surgeon in training before they are considered to have enough experience to ensure surgical safety.
Methods Cumulative Sum (CUSUM) analysis was performed using the surgical data of OPDs performed during the training period of board-certified expert surgeons of the Japanese Society of Hepato-Biliary-Pancreatic Surgery.
Results Fourteen HBP surgeons participated in this study and performed 334 OPDs during their training period. The median (interquartile range) values for operative time, blood loss, and length of hospital stay were 455 (397-519) minutes, 450 (234--716) ml, and 28 (21-38) days, respectively. CUSUM analysis showed inflection points at 20 surgeries performed for operative time. After 20 procedures, operative time was significantly shorter (461 min vs. 425 min, p = 0.021) and blood loss was significantly lower (470 ml vs. 340 ml, p = 0.038). No significant differences between within 20 and after 21 procedures were found in the complication rate (53% vs. 48%, p = 0.424) and rate of in-hospital deaths (1.5% vs.1.4%. p = 0.945). Up to 20 surgeries, PDAC and another malignant tumor had longer operative time than benign/low malignant diseases (486 min vs. 472 min vs. 429 min, p < 0.001), and higher blood loss (500 ml vs. 502 ml vs. 355 ml, p < 0.001). Mortality rate was higher at PDAC cases (5% vs. 0% vs. 0%, p = 0.01). After the 21 procedures, these outcomes were improved and no differences in by primary disease were observed. Multivariable analysis showed that within 20 surgeries were independent risk factors of longer operative time (HR2.6, p = 0.013) and higher blood loss (HR2.0, p = 0.049).
Conclusions To stabilize the surgical outcome of OPD for malignant disease, at least 20 surgeries should be performed at a certified institution during surgeon training.

This study aimed to determine whether the number of outpatient visits with a covering rheumatologist is associated with patient trust in their usual rheumatologist.
Methods Japanese adults with systemic lupus erythematosus (SLE) who met the 1997 revised classification criteria of the American College of Rheumatology and had outpatient visits with a covering rheumatologist in the past year were included.
We used the 11-item Japanese version of the modified Trust in Physician Scale (range 0?100) to assess patient trust. A general linear model with cluster-robust variance estimation was used to evaluate the association between the number of outpatient visits with covering rheumatologists and the patientfs trust in their usual rheumatologist.
Results Of the 515 enrolled participants, 421 patients with SLE were included in our analyses. Patients were divided into groups according to the number of outpatient visits with a covering rheumatologist in the past year as follows: no visits (59.9%; reference group), one to three visits (24.2%; low-frequency group), and four or more visits (15.9%; high-frequency group). The median Trust in Physician Scale score was 81.8 (interquartile range: 72.7?93.2). Both the low-frequency group (mean difference: -3.03; 95% confidence interval [CI] -5.93 to -0.80) and high-frequency group (mean difference: -4.17; 95% CI -7.77 to -0.58) exhibited lower trust in their usual rheumatologist.
Conclusion This study revealed that the number of outpatient visits with a covering rheumatologist was associated with lower trust in a patientfs usual rheumatologist. en-copyright= kn-copyright=

myocardial ischemia/reperfusion in anesthetized rats en-subtitle= kn-subtitle= en-abstract= kn-abstract=It has been suggested that sodium-glucose cotransporter 2 (SGLT2) inhibitors have cardioprotective effects during myocardial ischemia/reperfusion (I/R) independent of glucose-lowering action. However, the effects of SGLT2 inhibitors on structural damage to cardiomyocytes in the ischemic region during I/R remain unknown. We applied a microdialysis technique to the heart of anesthetized rats and investigated the effects of an SGLT2 inhibitor, dapagliflozin, on myocardial interstitial myoglobin levels in the ischemic region during coronary occlusion followed by reperfusion. Dapagliflozin was administered systemically (40 mu g/body iv) or locally via a dialysis probe (100 mu M and 1 mM) 30 min before coronary occlusion. In the vehicle group, coronary occlusion increased the dialysate myoglobin concentration in the ischemic region. Reperfusion further increased the dialysate myoglobin concentration. Intravenous administration of dapagliflozin reduced dialysate myoglobin concentration during ischemia and at 0-15 min after reperfusion, but local administration (100 mu M and 1 mM) did not. Therefore, acute systemic administration of dapagliflozin prior to ischemia has cardioprotective effects on structural damage during I/R. en-copyright= kn-copyright= en-aut-name=HayashidaTomohiro en-aut-sei=Hayashida en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KurokoYosuke en-aut-sei=Kuroko en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimizuShuji en-aut-sei=Shimizu en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AkiyamaTsuyoshi en-aut-sei=Akiyama en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SuezawaTakanori en-aut-sei=Suezawa en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KiokaYukio en-aut-sei=Kioka en-aut-mei=Yukio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KotaniYasuhiro en-aut-sei=Kotani en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShishidoToshiaki en-aut-sei=Shishido en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KasaharaShingo en-aut-sei=Kasahara en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiac Physiology, National Cerebral and Cardiovascular Center kn-affil= affil-num=5 en-affil=Department of Cardiovascular Surgery, Fukuyama City Hospital kn-affil= affil-num=6 en-affil=Department of Cardiovascular Surgery, Fukuyama City Hospital kn-affil= affil-num=7 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Research Promotion and Management, National Cerebral and Cardiovascular Center kn-affil= affil-num=9 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= en-keyword=Sodium-glucose-cotransporter 2 inhibitor kn-keyword=Sodium-glucose-cotransporter 2 inhibitor en-keyword=Dapagliflozin kn-keyword=Dapagliflozin en-keyword=Myocardial ischemia/reperfusion kn-keyword=Myocardial ischemia/reperfusion en-keyword=Cardiac microdialysis kn-keyword=Cardiac microdialysis en-keyword=Myoglobin kn-keyword=Myoglobin END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=5 article-no= start-page=377 end-page=386 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prognostic Efficacy of the Albumin Grade in Patients with Hepatocellular Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=We previously found that galbumin gradeh, formerly called the gALBS grade,h demonstrated significant capability for prognostic stratification in hepatocellular carcinoma (HCC) patients treated with lenvatinib. The purpose of the present study was to compare the performance of the albumin grade with that of the modified albumin-bilirubin (mALBI) grade in predicting overall survival of HCC patients with different BCLC stages and treatment types. We enrolled 7,645 Japanese patients newly diagnosed with HCC using the Akaike information criteria (AIC), likelihood ratio, and C-index in different Barcelona Clinic Liver Cancer (BCLC) stages and treatments. The albumin grade showed similar and slightly better performance than the mALBI grade for BCLC stage 0 and A and especially for patients who underwent curative surgery and ablation. In patients treated with transcatheter arterial chemoembolization, molecular targeted agents, and the best supportive care, the mALBI grade had better performance than the albumin grade. However, the differences of the indices were very small in all scenarios. Overall, the albumin grade was comparable in efficacy to the mALBI grade, showing particular benefit for patients with early-stage HCC. en-copyright= kn-copyright= en-aut-name=HiranoYuichi

However, their safety has not been sufficiently explored. This study aimed to validate this management method.
Methods: This retrospective, multicenter study analyzed the characteristics and outcomes of patients who underwent gastric endoscopic submucosal dissection between July 2017 and June 2019. The patients were categorized according to the use of warfarin or DOACs.
Results: Among the 62 eligible patients, 53 (85%) were male (median age, 76 years). Warfarin was used in 10 patients (16%) and DOACs in 52 patients (84%). Fourteen patients taking DOACs (27%) used concomitant antiplatelet agents, with seven patients (13%) continuing treatment at the time of the endoscopic procedure. No postprocedural bleeding occurred in patients receiving warfarin (0%), whereas 10 cases (19%) of bleeding occurred in patients receiving DOACs: rivaroxaban, 0% (0/22); dabigatran, 0% (0/2); edoxaban, 43% (6/14); and apixaban, 29% (4/14). The type of anticoagulant (P < 0.01) and continuation of antiplatelet therapy (P = 0.02) were risk factors for postprocedural bleeding in patients receiving DOACs. Intraprocedural bleeding requiring transfusion or symptomatic thromboembolic events were not reported.
Conclusions: Continuous warfarin therapy is preferred. DOAC withdrawal 1 day before a procedure is associated with a high bleeding rate, which may differ for different types of anticoagulants. The continuation of antiplatelet medications in patients receiving DOACs carries a high risk of bleeding and is a future challenge. en-copyright= kn-copyright= en-aut-name=HirataShoichiro

kn-subtitle= en-abstract= kn-abstract=In recent years, research on organ-on-a-chip technology has been flourishing, particularly for drug screening and disease model development. Fibroblasts and vascular endothelial cells engage in crosstalk through paracrine signaling and direct cell-cell contact, which is essential for the normal development and function of the heart. Therefore, to faithfully recapitulate cardiac function, it is imperative to incorporate fibroblasts and vascular endothelial cells into a heart-on-a-chip model. Here, we report the development of a human heart-on-a-chip composed of induced pluripotent stem cell (iPSC)-derived cardiomyocytes, fibroblasts, and vascular endothelial cells. Vascular endothelial cells cultured on microfluidic channels responded to the flow of culture medium mimicking blood flow by orienting themselves parallel to the flow direction, akin to in vivo vascular alignment in response to blood flow. Furthermore, the flow of culture medium promoted integrity among vascular endothelial cells, as evidenced by CD31 staining and lower apparent permeability. The tri-culture condition of iPSC-derived cardiomyocytes, fibroblasts, and vascular endothelial cells resulted in higher expression of the ventricular cardiomyocyte marker IRX4 and increased contractility compared to the bi-culture condition with iPSC-derived cardiomyocytes and fibroblasts alone. Such tri-culture-derived cardiac tissues exhibited cardiac responses similar to in vivo hearts, including an increase in heart rate upon noradrenaline administration. In summary, we have achieved the development of a heart-on-a-chip composed of cardiomyocytes, fibroblasts, and vascular endothelial cells that mimics in vivo cardiac behavior. en-copyright= kn-copyright= en-aut-name=LiuYun en-aut-sei=Liu en-aut-mei=Yun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KamranRumaisa en-aut-sei=Kamran en-aut-mei=Rumaisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HanXiaoxia en-aut-sei=Han en-aut-mei=Xiaoxia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangMengxue en-aut-sei=Wang en-aut-mei=Mengxue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=LiQiang en-aut-sei=Li en-aut-mei=Qiang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=LaiDaoyue en-aut-sei=Lai en-aut-mei=Daoyue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NaruseKeiji en-aut-sei=Naruse en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakahashiKen en-aut-sei=Takahashi en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Induced pluripotent stem cells kn-keyword=Induced pluripotent stem cells en-keyword=Fibroblasts kn-keyword=Fibroblasts en-keyword=Endothelial cells kn-keyword=Endothelial cells en-keyword=Heart kn-keyword=Heart en-keyword=Heart-on-a-chip kn-keyword=Heart-on-a-chip en-keyword=Organ-on-a-chip kn-keyword=Organ-on-a-chip END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=542 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240815 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluating the impact of a trial of labor after cesarean section on labor duration: a retrospective cohort study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Cesarean section (C-section) rates are increasing globally, and repeated C-sections are associated with increased maternal morbidity. Trial of labor after C-section (TOLAC) is an approach to reduce the recurrence of C-sections. However, limited research exists on the impact of cesarean scars on labor duration in TOLAC, considering the termination of labor through C-section and selection bias. This study aimed to investigate the impact of cesarean scars on labor duration in TOLAC participants, accounting for potential confounding factors and biases.
Methods This retrospective cohort study included 2,964 women who attempted vaginal birth at a single center in Japan from 2012 to 2021. The study categorized participants into TOLAC (n = 187) and non-TOLAC (n = 2,777) groups. Propensity scores were calculated based on 14 factors that could influence labor duration, and inverse probability of treatment weighting (IPTW) was applied. Cox proportional hazards regression analysis estimated hazard ratios (HRs) for labor duration, with and without IPTW adjustment. Sensitivity analyses used propensity score matching, bootstrapping, and interval censoring to address potential biases, including recall bias in the reported onset of labor.
Results The unadjusted HR for labor duration in the TOLAC group compared to the non-TOLAC group was 0.83 (95% CI: 0.70-0.98, P = 0.027), indicating a longer labor duration in the TOLAC group. After adjusting for confounding factors using IPTW, the HR was 0.98 (95% CI: 0.74-1.30, P = 0.91), suggesting no significant difference in labor duration between the groups. Sensitivity analyses using propensity score matching, bootstrapping, and interval censoring yielded consistent results. These findings suggested that the apparent association between TOLAC and longer labor duration was because of confounding factors rather than TOLAC itself.
Conclusions After adjusting for confounding factors and addressing potential biases, cesarean scars had a limited impact on labor duration in TOLAC participants. Maternal and fetal characteristics may have a more substantial influence on labor duration. en-copyright= kn-copyright= en-aut-name=OobaHikaru en-aut-sei=Ooba en-aut-mei=Hikaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MakiJota en-aut-sei=Maki en-aut-mei=Jota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Okayama University Hospital kn-affil= en-keyword=Labor duration kn-keyword=Labor duration en-keyword=Trial of labor after cesarean section kn-keyword=Trial of labor after cesarean section en-keyword=Vaginal birth kn-keyword=Vaginal birth en-keyword=Cesarean section kn-keyword=Cesarean section en-keyword=Propensity scores kn-keyword=Propensity scores en-keyword=IPTW kn-keyword=IPTW END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=5536 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240716 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Controlling 229Th isomeric state population in a VUV transparent crystal en-subtitle= kn-subtitle= en-abstract= kn-abstract=The radioisotope thorium-229 (Th-229) is renowned for its extraordinarily low-energy, long-lived nuclear first-excited state. This isomeric state can be excited by vacuum ultraviolet (VUV) lasers and Th-229 has been proposed as a reference transition for ultra-precise nuclear clocks. To assess the feasibility and performance of the nuclear clock concept, time-controlled excitation and depopulation of the Th-229 isomer are imperative. Here we report the population of the Th-229 isomeric state through resonant X-ray pumping and detection of the radiative decay in a VUV transparent Th-229-doped CaF2 crystal. The decay half-life is measured to 447(25) s, with a transition wavelength of 148.18(42) nm and a radiative decay fraction consistent with unity. Furthermore, we report a new "X-ray quenching" effect which allows to de-populate the isomer on demand and effectively reduce the half-life. Such controlled quenching can be used to significantly speed up the interrogation cycle in future nuclear clock schemes. en-copyright= kn-copyright= en-aut-name=HirakiTakahiro en-aut-sei=Hiraki

ancillary analysis of the SGSG-012/GOTIC-004/Intergroup study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background We previously demonstrated the applicability of the concept of gplatinum sensitivityh in recurrent endometrial cancer. Although immune checkpoint inhibitors have been widely incorporated into endometrial cancer treatment, the debate continues regarding treatment options in patients with recurrent endometrial cancer who have previously received platinum-based chemotherapy. In this study, we assessed the duration of response to secondary platinum-based treatment using pooled data from the SGSG-012/GOTIC-004/Intergroup study.
Methods Among the 279 participants in the SGSG-012/GOTIC-004/Intergroup study wherein platinum-based chemotherapy was re-administered for managing recurrent endometrial cancer between January 2005 and December 2009, 130 (47%) responded to chemotherapy. We compared the relationship between platinum-free interval and duration of secondary platinum-based treatment using pooled data.
Results In 40 patients (31%), the duration of response to secondary platinum-based treatment exceeded the platinum-free interval. The duration of response to secondary platinum-based treatment exceeded 12 months in 51 patients (39%) [platinum-free interval:? Conclusions Re-administration of platinum-based chemotherapy for recurrent endometrial cancer may result in a long-term response exceeding the platinum-free interval in some patients. Even in the current situation, where immune checkpoint inhibitors have been introduced, re-administration of platinum-based chemotherapy is worth considering. en-copyright= kn-copyright=

pandemic in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
In the global aging, the coronavirus disease 2019 (COVID-19) pandemic may have affected the place of death (PoD) in Japan, where hospital deaths have dominated for decades. We analyzed the PoD trends before and during the COVID-19 pandemic in Japan.
Methods
This nationwide observational study used vital statistics based on death certificates from Japan between 1951 and 2021. The proportion of PoD; deaths at home, hospitals, and nursing homes; and annual percentage change (APC) were estimated using joinpoint regression analysis. Analyses were stratified by age groups and causes of death.
Results
After 2019, home deaths exhibited upward trends, while hospital death turned into downward trends. By age, no significant trend change was seen in the 0-19 age group, while hospital deaths decreased in the 20-64 age group in 2019. The trend change in home death in the >= 65 age group significantly increased since 2019 with an APC of 12.3% (95% confidence interval [CI]: 9.0 to 15.7), while their hospital death trends decreased by -4.0% (95% CI: -4.9 to -3.1) in 2019-2021. By cause of death, home death due to cancer and the old age increased since 2019 with an APC of 29.3% (95% CI: 25.4 to 33.2) and 8.8% (95% CI: 5.5 to 12.2), respectively.
Conclusion
PoD has shifted from hospital to home during the COVID-19 pandemic in Japan. The majority of whom were older population with cancer or old age. en-copyright= kn-copyright= en-aut-name=ShibataMasashi en-aut-sei=Shibata en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KoyamaToshihiro en-aut-sei=Koyama en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KashiwagiHideyuki en-aut-sei=Kashiwagi en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of General Medicine, Iizuka Hospital kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pharmaceutical Biomedicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Transitional and Palliative Care, Iizuka Hospital kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=391 cd-vols= no-issue=2 article-no= start-page=249 end-page=267 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221122 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The medaka mutant deficient in eyes shut homolog exhibits opsin transport defects and enhanced autophagy in retinal photoreceptors en-subtitle= kn-subtitle= en-abstract= kn-abstract=Eyes shut homolog (EYS) encodes a proteoglycan and the human mutation causes retinitis pigmentosa type 25 (RP25) with progressive retinal degeneration. RP25 most frequently affects autosomal recessive RP patients with many ethnic backgrounds. Although studies using RP models have facilitated the development of therapeutic medications, Eys has been lost in rodent model animals. Here we examined the roles for Eys in the maintenance of photoreceptor structure and function by generating eys-null medaka fish using the CRISPR-Cas9 system. Medaka EYS protein was present near the connecting cilium of wild-type photoreceptors, while it was absent from the eys?/? retina. The mutant larvae exhibited a reduced visual motor response compared with wild-type. In contrast to reported eys-deficient zebrafish at the similar stage, no retinal cell death was detected in the 8-month post-hatching (8-mph) medaka eys mutant. Immunohistochemistry showed a significant reduction in the length of cone outer segments (OSs), retention of OS proteins in the inner segments of photoreceptors, and abnormal filamentous actin network at the base of cone OSs in the mutant retina by 8 mph. Electron microscopy revealed aberrant structure of calyceal processes, numerous vesiculation and lamellar interruptions, and autophagosomes in the eys-mutant cone photoreceptors. In situ hybridization showed an autophagy component gene, gabarap, was ectopically expressed in the eys-null retina. These results suggest eys is required for regeneration of OS, especially of cone photoreceptors, and transport of OS proteins by regulating actin filaments. Enhanced autophagy may delay the progression of retinal degeneration when lacking EYS in the medaka retina. en-copyright= kn-copyright= en-aut-name=SatoKeita en-aut-sei=Sato en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LiuYang en-aut-sei=Liu en-aut-mei=Yang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamashitaTakahiro en-aut-sei=Yamashita en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OhuchiHideyo en-aut-sei=Ohuchi en-aut-mei=Hideyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Cytology and Histology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Biophysics, Graduate School of Science, Kyoto University kn-affil= affil-num=4 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Eyes shut homolog kn-keyword=Eyes shut homolog en-keyword=Eys kn-keyword=Eys en-keyword=Retinitis pigmentosa kn-keyword=Retinitis pigmentosa en-keyword=RP25 kn-keyword=RP25 en-keyword=Cone photoreceptor kn-keyword=Cone photoreceptor en-keyword=Autophagy kn-keyword=Autophagy END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=’´‘ŽYŽ™‚É‚¨‚¯‚錌´ˆêŽ_‰»’‚‘f‚ÆDŽ_‹…‚Ìo¶Œã‚Ìc’f“I‰ðÍ kn-title=Postnatal longitudinal analysis of serum nitric oxide and eosinophil counts in extremely preterm infants en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=WATANABEHirokazu en-aut-sei=WATANABE en-aut-mei=Hirokazu kn-aut-name=“nç³G˜a kn-aut-sei=“nç³ kn-aut-mei=G˜a aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=‰ªŽR‘åŠw‘åŠw‰@ˆãŽ•–òŠw‘‡Œ¤‹†‰È END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=5 article-no= start-page=e8933 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202405 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Decades of stability of conjunctival vascular malformations in two patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 65-year-old woman with diabetic retinopathy underwent glaucoma surgery to construct a filtering bleb adjacent to conjunctival hemangioma, and showed bleb function and stable hemangioma for a decade.

We investigated the crystallization behaviors of blends of cyclic polyethylene (C-PE) and linear polyethylene (L-PE) in a quiescent state to elucidate the role of this novel entanglement in crystallization. The samples were prepared by mixing the prepared C-PE and L-PE specimens at L-PE weight fraction (ƒ³L-PE) values of 0?100?wt%, with the weight average molecular weights of C-PE and L-PE being 175?~?103 and 154?~?103, respectively. The isothermal crystallization behaviors were analyzed through polarizing optical microscopy (POM) and differential scanning calorimetry (DSC). The morphology observed through POM was similar to that of ƒ³L-PE. From the time evolution of the heat flow measured via DSC, we obtained the half-crystallization time (t1/2) values as functions of ƒ³L-PE at different degrees of supercooling (ƒ¢T). The 1/t1/2 values of the C-PE and L-PE homopolymers were approximately the same at ƒ¢T?=?25.5 and 26.5?K. At a larger ƒ¢T value, the 1/t1/2 value of C-PE was significantly larger than that of L-PE. In contrast, 1/t1/2 reached a minimum value at ƒ³L-PE?=?30?40?wt%, irrespective of ƒ¢T. As the entanglement density increased with increasing ƒ³L-PE, the crystallization rate was expected to decrease monotonically. By considering the experimental relationship between 1/t1/2 and ƒ³L-PE, we speculated that the suppression of crystallization in the blended system was caused by a novel entanglement formed by the penetration of the L-PE chain into the C-PE chain. en-copyright= kn-copyright= en-aut-name=KobayashiKeiko en-aut-sei=Kobayashi en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AtarashiHironori en-aut-sei=Atarashi en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamazakiShinichi en-aut-sei=Yamazaki en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KimuraKunio en-aut-sei=Kimura en-aut-mei=Kunio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=160 cd-vols= no-issue=14 article-no= start-page=144304 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240409 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Analysis on high-resolution spectrum of the S1?S0 transition of free-base phthalocyanine en-subtitle= kn-subtitle= en-abstract= kn-abstract=A high-resolution absorption spectrum of the S-1-S-0 transition of free-base phthalocyanine was observed and analyzed with improved reliability. The spectrum, with a partially resolved rotational structure, was obtained by using the buffer-gas cooling technique and a single-mode tunable laser. Our new analysis reveals that the S-1 <- S-0 0(0)(0) band belongs to the a-type transition, where the electronic transition moment aligns parallel to the NH-HN direction, allowing the assignment of the S-1 state to B-1(3u). These results agree with a prior study using supersonic expansion and are well supported by theoretical calculations. Interestingly, the rotational constant B in the S-1 state, which is often smaller than that in the ground state for typical molecules, was found to be slightly larger than that in the S-0 (1)A(g) state. This suggests a change in the character of pi bonds with the electronic excitation. en-copyright= kn-copyright= en-aut-name=MiyamotoYuki en-aut-sei=Miyamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiramotoAyami en-aut-sei=Hiramoto en-aut-mei=Ayami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IwakuniKana en-aut-sei=Iwakuni en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KumaSusumu en-aut-sei=Kuma en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=EnomotoKatsunari en-aut-sei=Enomoto en-aut-mei=Katsunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakayamaNaofumi en-aut-sei=Nakayama en-aut-mei=Naofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=BabaMasaaki en-aut-sei=Baba en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Institute for Laser Science, University of Electro-Communications kn-affil= affil-num=4 en-affil=Atomic, Molecular and Optical Physics Laboratory, RIKEN kn-affil= affil-num=5 en-affil=Department of Physics, University of Toyama kn-affil= affil-num=6 en-affil=CONFLEX Corporation kn-affil= affil-num=7 en-affil=Molecular Photoscience Research Center, Kobe University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=249 cd-vols= no-issue= article-no= start-page=440 end-page=452 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=How do water-mediated interactions and osmotic second virial coefficients vary with particle size? en-subtitle= kn-subtitle= en-abstract= kn-abstract=We examine quantitatively the solute-size dependences of the effective interactions between nonpolar solutes in water and in a simple liquid. The potential w(r) of mean force and the osmotic second virial coefficients B are calculated with high accuracy from molecular dynamics simulations. As the solute diameter increases from methane's to C60's with the solute?solute and solute?solvent attractive interaction parameters fixed to those for the methane?methane and methane?water interactions, the first minimum of w(r) lowers from ?1.1 to ?4.7 in units of the thermal energy kT. Correspondingly, the magnitude of B (<0) increases proportional to ƒÐƒ¿ with some power close to 6 or 7, which reinforces the solute-size dependence of B found earlier for a smaller range of ƒÐ [H. Naito, R. Okamoto, T. Sumi and K. Koga, J. Chem. Phys., 2022, 156, 221104]. We also demonstrate that the strength of the attractive interactions between solute and solvent molecules can qualitatively change the characteristics of the effective pair interaction between solute particles, both in water and in a simple liquid. If the solute?solvent attractive force is set to be weaker (stronger) than a threshold, the effective interaction becomes increasingly attractive (repulsive) with increasing solute size. en-copyright= kn-copyright= en-aut-name=NaitoHidefumi en-aut-sei=Naito en-aut-mei=Hidefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SumiTomonari en-aut-sei=Sumi en-aut-mei=Tomonari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KogaKenichiro en-aut-sei=Koga en-aut-mei=Kenichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=205 cd-vols= no-issue=10 article-no= start-page=346 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230929 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Flavobacterium okayamense sp. nov. isolated from surface seawater en-subtitle= kn-subtitle= en-abstract= kn-abstract=Strain KK2020170T, a Gram-stain negative, yellow colony-forming bacterium, was isolated from surface seawater sampled in Kojima Bay, Okayama, Japan. Phylogenetic analysis based on the 16S rRNA gene revealed that strain KK2020170T belongs to the genus Flavobacterium, with Flavobacterium haoranii LQY-7T (98.1% similarity) being its closest relative, followed by Flavobacterium sediminis MEBiC07310T (96.9%) and Flavobacterium urocaniciphilum YIT 12746T (96.0%). Whole-genome shotgun sequencing showed that strain KK2020170T, when paralleled with F. haoranii LQY-7 T, had 81.3% average nucleotide identity, and 24.6% in silico DNA?DNA hybridization values, respectively. The DNA G?+?C content of strain KK2020170T was 31.1 mol%. The most abundant fatty acids (>?10%) of strain KK2020170T were iso-C15:?0, iso-C17:?0 3-OH and iso-C15:?1 G. The dominant respiratory quinone of the strain was menaquinone MK-6. Based on the phylogenetic and phenotypic analysis results, we propose that strain KK2020170T represents a novel species, for which the name Flavobacterium okayamense sp. nov. has been proposed. The type strain is KK2020170T (=?ATCC TSD-280 T?=?NBRC 115344 T). en-copyright= kn-copyright= en-aut-name=KitaharaKei en-aut-sei=Kitahara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MuzemboBasilua Andre en-aut-sei=Muzembo en-aut-mei=Basilua Andre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorohoshiSho en-aut-sei=Morohoshi en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KunihiroTadao en-aut-sei=Kunihiro en-aut-mei=Tadao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TazatoNozomi en-aut-sei=Tazato en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhnoAyumu en-aut-sei=Ohno en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UesakaKazuma en-aut-sei=Uesaka en-aut-mei=Kazuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TaniguchiMakoto en-aut-sei=Taniguchi en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=TechnoSuruga Laboratory Co., Ltd kn-affil= affil-num=4 en-affil=TechnoSuruga Laboratory Co., Ltd kn-affil= affil-num=5 en-affil=TechnoSuruga Laboratory Co., Ltd kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Bioagricultural Sciences, Nagoya University kn-affil= affil-num=8 en-affil=Oral Microbiome Center, Taniguchi Dental Clinic kn-affil= affil-num=9 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Bacteroidota kn-keyword=Bacteroidota en-keyword=Flavobacterium kn-keyword=Flavobacterium en-keyword=New taxa kn-keyword=New taxa en-keyword=Sea water kn-keyword=Sea water END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=7 article-no= start-page=1886 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Prospective Observational Study on Gastric Endoscopic Submucosal Dissection under Continuous Administration of Antithrombotic Agents en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: This study aimed to assess the completion rate and postoperative bleeding incidence of endoscopic submucosal dissection (ESD) for gastric tumors under continuous antithrombotic therapy.

Results: The en bloc resection rates (100% in the continuous antithrombotic therapy group vs. 100% in the non-antithrombotic therapy group) and complete resection rates (97.0% vs. 96.3%, respectively) were high and comparable between the groups. No significant differences were found in the specimen size or procedure time. Perforation rates were low (0% vs. 2.3%, respectively) and were not significantly different between the groups. However, postoperative bleeding occurred significantly more frequently in the continuous antithrombotic therapy group (10.2% vs. 4.2%, respectively) than in the non-antithrombotic therapy group. The subgroup analysis revealed a higher incidence of postoperative bleeding in patients receiving thienopyridine derivatives. Conclusions: Continuous administration of antithrombotic agents, especially thienopyridines, increased the risk of postprocedural hemorrhage following gastric ESD. These findings support the need for careful consideration of pharamcological management before ESD, aligning with the current guidelines. en-copyright= kn-copyright= en-aut-name=KawaiDaisuke en-aut-sei=Kawai en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakenakaRyuta en-aut-sei=Takenaka en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ObataTaisuke en-aut-sei=Obata en-aut-mei=Taisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoTakashi en-aut-sei=Yamamoto en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HirataShoichiro en-aut-sei=Hirata en-aut-mei=Shoichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiuraKo en-aut-sei=Miura en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakemotoKoji en-aut-sei=Takemoto en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TsugenoHirofumi en-aut-sei=Tsugeno en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujikiShigeatsu en-aut-sei=Fujiki en-aut-mei=Shigeatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterology, Tsuyama Chuo Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology, Tsuyama Chuo Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Tsuyama Chuo Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology, Tsuyama Chuo Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology, Tsuyama Chuo Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology, Tsuyama Chuo Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology, Tsuyama Chuo Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology, Tsuyama Chuo Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterology, Tsuyama Chuo Hospital kn-affil= en-keyword=endoscopic submucosal dissection kn-keyword=endoscopic submucosal dissection en-keyword=antithrombotic agents kn-keyword=antithrombotic agents en-keyword=thienopyridine kn-keyword=thienopyridine en-keyword=gastric tumor kn-keyword=gastric tumor en-keyword=postoperative bleeding kn-keyword=postoperative bleeding en-keyword=delayed bleeding kn-keyword=delayed bleeding END start-ver=1.4 cd-journal=joma no-vol=42 cd-vols= no-issue=2 article-no= start-page=158 end-page=164 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230827 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of the ear ossicles with photon-counting detector CT en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recently, computed tomography with photon-counting detector (PCD-CT) has been developed to enable high-resolution imaging at a lower radiation dose. PCD-CT employs a photon-counting detector that can measure the number of incident X-ray photons and their energy. The newly released PCD-CT (NAEOTOM Alpha, Siemens Healthineers, Forchheim, Germany) has been in clinical use at our institution since December 2022. The PCD-CT offers several advantages over current state-of-the-art energy-integrating detector CT (EID-CT). The PCD-CT does not require septa to create a detector channel, while EID-CT does. Therefore, downsizing the anode to achieve higher resolution does not affect the dose efficiency of the PCD-CT. CT is an indispensable modality for evaluating ear ossicles. The ear ossicles and joints are clearly depicted by PCD-CT. In particular, the anterior and posterior legs of the stapes, which are sometimes unclear on conventional CT scans, can be clearly visualized. We present cases of congenital anomalies of the ossicular chain, ossicular chain dislocation, tympanosclerosis, and cholesteatoma in which PCD-CT was useful. This short article reports the usefulness of PCD-CT in the 3D visualization of the ear ossicles. en-copyright= kn-copyright= en-aut-name=TakahashiYuka en-aut-sei=Takahashi en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugayaAkiko en-aut-sei=Sugaya en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AsanoYudai en-aut-sei=Asano en-aut-mei=Yudai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KojimaKatsuhide en-aut-sei=Kojima en-aut-mei=Katsuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MorimitsuYusuke en-aut-sei=Morimitsu en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AkagiNoriaki en-aut-sei=Akagi en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ItohToshihide en-aut-sei=Itoh en-aut-mei=Toshihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Otolaryngology?Head and Neck Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of CT?Research and Collaboration, Siemens Healthineers kn-affil= affil-num=9 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Photon-counting detector computed tomography kn-keyword=Photon-counting detector computed tomography en-keyword=Energy-integrating detectors kn-keyword=Energy-integrating detectors en-keyword=Ear ossicles kn-keyword=Ear ossicles en-keyword=High-resolution imaging kn-keyword=High-resolution imaging en-keyword=3D kn-keyword=3D END start-ver=1.4 cd-journal=joma no-vol=143 cd-vols= no-issue= article-no= start-page=110894 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=First-principles molecular dynamics simulations for the properties of boron-doped tetrahedral amorphous carbon en-subtitle= kn-subtitle= en-abstract= kn-abstract=Based on first-principles molecular dynamics (FPMD) simulations combined with a liquid quenching method, we study the effects of boron doping at 0 %, 2 %, 4 %, 6 % on the properties of tetrahedral amorphous carbon (ta-C) with an initial density of 3.0 g/cm3. The results of bond structures and internal stress show the promotion of graphitization with increase in the concentration of boron doping. In addition, simulation of electronic states reveals that the Fermi level shifts to valence band and the intensity of density of electronic states near Fermi level increases with the boron concentration increasing. A covalent bond formation between carbon and boron atoms is also shown by analyzing projected densities of electronic states (PDOS) and electron density distribution. The results of electronic state and bond formation strongly indicate that the boron-doped ta-C is like a p-type semiconductor. The present simulation results provide useful information for deeper understanding on the physical properties of boron-doped ta-C. en-copyright= kn-copyright= en-aut-name=YueQiang en-aut-sei=Yue en-aut-mei=Qiang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YokoyaTakayoshi en-aut-sei=Yokoya en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MuraokaYuji en-aut-sei=Muraoka en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=Boron-doped tetrahedral amorphous carbon kn-keyword=Boron-doped tetrahedral amorphous carbon en-keyword=First-principles molecular dynamics kn-keyword=First-principles molecular dynamics en-keyword=Liquid quenching method kn-keyword=Liquid quenching method END start-ver=1.4 cd-journal=joma no-vol=626 cd-vols= no-issue=7999 article-no= start-page=670 end-page=677 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240131 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Oxygen-evolving photosystem II structures during S1?S2?S3 transitions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photosystem II (PSII) catalyses the oxidation of water through a four-step cycle of Si states (i?=?0?4) at the Mn4CaO5 cluster1,2,3, during which an extra oxygen (O6) is incorporated at the S3 state to form a possible dioxygen4,5,6,7. Structural changes of the metal cluster and its environment during the S-state transitions have been studied on the microsecond timescale. Here we use pump-probe serial femtosecond crystallography to reveal the structural dynamics of PSII from nanoseconds to milliseconds after illumination with one flash (1F) or two flashes (2F). YZ, a tyrosine residue that connects the reaction centre P680 and the Mn4CaO5 cluster, showed structural changes on a nanosecond timescale, as did its surrounding amino acid residues and water molecules, reflecting the fast transfer of electrons and protons after flash illumination. Notably, one water molecule emerged in the vicinity of Glu189 of the D1 subunit of PSII (D1-E189), and was bound to the Ca2+ ion on a sub-microsecond timescale after 2F illumination. This water molecule disappeared later with the concomitant increase of O6, suggesting that it is the origin of O6. We also observed concerted movements of water molecules in the O1, O4 and Cl-1 channels and their surrounding amino acid residues to complete the sequence of electron transfer, proton release and substrate water delivery. These results provide crucial insights into the structural dynamics of PSII during S-state transitions as well as O?O bond formation. en-copyright= kn-copyright= en-aut-name=LiHongjie en-aut-sei=Li

sweetpotato weevil Euscepes postfasciatus (Coleoptera: Curculionidae) on sweet potato stems en-subtitle= kn-subtitle= en-abstract= kn-abstract=The West Indian sweetpotato weevil, Euscepes postfasciatus, a serious pest of sweet potatoes, is being eradicated by sterile insect technique (SIT) in the south-western islands of Japan. Information on the diurnal movement of the target pests on host plants and where mating and egg-laying behavior occurs on the host is important for the application of SIT, which eradicates the target pest through mating of released sterile males and wild females. However, little such information is available on this species. In this study, male and female adults were released on host plants to examine the diurnal distribution on seedlings according to sex, as well as the sites where mounting behavior and egg laying occurs. The results showed that females left the host plant more frequently at night, whereas males were more likely to remain on the host plant at night. Both males and females stayed on the nodes of the host plant during the daytime. Mounting behavior also tended to occur more often at nodes. Furthermore, compared to unmated females, mated females stayed at the vertical top of the seedlings. However, it was found that eggs were often laid close to the roots rather than at the top of the vertical stems, even when the seedlings were placed upside down. The results of previous studies and this study will be discussed from the perspective of the application of SIT against E. postfasciatus. en-copyright= kn-copyright= en-aut-name=UrasakiKimiko en-aut-sei=Urasaki en-aut-mei=Kimiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumuraKentarou en-aut-sei=Matsumura en-aut-mei=Kentarou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Okinawa Prefectural Plant Protection Center kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Diurnal pattern kn-keyword=Diurnal pattern en-keyword=Eggs kn-keyword=Eggs en-keyword=Mating system kn-keyword=Mating system en-keyword=Mounting kn-keyword=Mounting en-keyword=Weevil kn-keyword=Weevil END start-ver=1.4 cd-journal=joma no-vol=185 cd-vols= no-issue= article-no= start-page=133 end-page=146 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240222 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Study on a Cooperation Procedure to Construct Whole and Annual Guidance Plans of Care and Education in a Nursery School for Children Aged Zero to Two kn-title=‚O`‚QÎŽ™‘ÎÛ•ÛˆçŽ{Ý‚É‚¨‚¯‚é•Ûˆç‚Ì‘S‘Ì“I‚ÈŒv‰æ‹y‚Ñ”NŠÔŽw“±Œv‰æ쬂̂½‚ß‚ÌŒ¤‹†ŽÒ‚Ì‹¦“­Žè‡‚ÌŒŸ“¢ en-subtitle= kn-subtitle= en-abstract= kn-abstract=@‚O`‚QÎŽ™‘ÎÛ•ÛˆçŽ{Ý‚É‚¨‚¢‚ÄCƒJƒŠƒLƒ…ƒ‰ƒ€Eƒ}ƒlƒWƒƒ“ƒg‚ÌŽÀŒ»‰Â”\‚ÈC•Ûˆç–Ú•W‚Ì–¾Šm‰»‚©‚ç•Ûˆç‚Ì‘S‘Ì“I‚ÈŒv‰æ‹y‚Ñ”NŠÔŽw“±Œv‰æ‚Ì쬂܂łðˆê“x‚ÉŒø—¦“I‚És‚¤‚½‚ß‚É‚ÍCŽŸ‚ÌŽ–€‚ð‹s‚·‚é•K—v‚ª‚ ‚é‚Æ‚¢‚¦‚éB?‰€‚Ì•ÛˆçŽÀ‘H‚ÉŠÖ‚·‚é—ÝÏŽ‘—¿‚©‚ç•Ûˆç‚Ì‘S‘Ì“I‚ÈŒv‰æ‹y‚Ñ”NŠÔŽw“±Œv‰æ‚ð쬂·‚éC?•Ûˆç‚Ì‚Ë‚ç‚¢E“à—e‚ÉŠÖ‚·‚鑂̊ðŽÀŒ»‚Å‚«‚錩’Ê‚µ‚𓾂éC?•s‘«‚µ‚Ä‚¢‚é•Ûˆç“à—e‚Ì“à‚Å“––Ê’…Žè‚·‚é•K—v‚Ì‚ ‚鎖•¿‚𖾊m‚É‚·‚éC?쬂³‚ꂽ‘S”NŠÔŽw“±Œv‰æ‚Æ“––Ê’…Žè‚·‚鎖•¿‚𓥂܂¦‚ÄCHˆçE•ÛŒ’EˆÀ‘S‚Ì”NŠÔŒv‰æ‚ð쬂·‚éC?‹³ˆçŠî–{–@‚ÌŠÏ“_‚©‚çC–¾Šm‰»‚³‚ꂽ•Ûˆç–Ú•W‚ðŒŸ“¢‚µCC³‚ª•K—v‚Èê‡C³‚·‚éB–{Œ¤‹†‚Å‚ÍC‚±‚ê‚ç‚ÌŽ–€‚ð‹s‚Å‚«‚錤‹†ŽÒ‚Ì‹¦“­Žè‡‚ðC‚O`‚QÎŽ™‘ÎÛ•ÛˆçŽ{Ý‚`‚ł̃AƒNƒVƒ‡ƒ“ƒŠƒT[ƒ`‚ð’Ê‚µ‚Ē莮‰»‚µ‚Ä‚¢‚éB en-copyright= kn-copyright= en-aut-name=YOKOMATSUTomoyoshi en-aut-sei=YOKOMATSU en-aut-mei=Tomoyoshi kn-aut-name=‰¡¼—F‹` kn-aut-sei=‰¡¼ kn-aut-mei=—F‹` aut-affil-num=1 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=‰ªŽR‘åŠwŠwpŒ¤‹†‰@‹³ˆçŠwˆæ en-keyword=ƒJƒŠƒLƒ…ƒ‰ƒ€Eƒ}ƒlƒWƒƒ“ƒg kn-keyword=ƒJƒŠƒLƒ…ƒ‰ƒ€Eƒ}ƒlƒWƒƒ“ƒg en-keyword=‚O`‚QÎŽ™‘ÎÛ•ÛˆçŽ{Ý kn-keyword=‚O`‚QÎŽ™‘ÎÛ•ÛˆçŽ{Ý en-keyword=•Ûˆç‚Ì‘S‘Ì“I‚ÈŒv‰æ kn-keyword=•Ûˆç‚Ì‘S‘Ì“I‚ÈŒv‰æ en-keyword=”NŠÔŽw“±Œv‰æ kn-keyword=”NŠÔŽw“±Œv‰æ en-keyword=Œ¤‹†ŽÒ‚Ì‹¦“­Žè‡ kn-keyword=Œ¤‹†ŽÒ‚Ì‹¦“­Žè‡ END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=79 end-page=83 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Utility of Combined Use of Transabdominal Ultrasonography and Fecal Immunochemical Test Examinations in Ulcerative Colitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study examined the utility of the combined use of transabdominal ultrasonography (TUS) and fecal immunochemical testing (FIT) to detect mucosal inflammation, vis-a-vis the Mayo endoscopic subscore (MES), in ulcerative colitis (UC). Sixty-three UC patients who underwent TUS and FIT were retrospectively enrolled. For TUS, the colon was divided into five segments, and the bowel wall thickness was measured and evaluated. The accuracy of FIT (> 100 ng/ml) in detecting mucosal inflammation (MES>0) was 0.93, whereas that of TUS (BWT>2 mm) in each segment was 0.84-0.97. The combined use of TUS and FIT may be helpful in noninvasive treatment strategies. en-copyright= kn-copyright= en-aut-name=TakaharaMasahiro en-aut-sei=Takahara en-aut-mei=Masahiro kn-aut-name=

oncolytic adenovirus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Pancreatic cancer is an aggressive, immunologically gcoldh tumor. Oncolytic virotherapy is a promising treatment to overcome this problem. We developed a telomerase-specific oncolytic adenovirus armed with p53 gene (OBP-702).
Methods: We investigated the efficacy of OBP-702 for pancreatic cancer, focusing on its long-term effects via long-lived memory CD8?+?T cells including tissue-resident memory T cells (TRMs) and effector memory T cells (TEMs) differentiated from effector memory precursor cells (TEMps).
Results: First, in vitro, OBP-702 significantly induced adenosine triphosphate (ATP), which is important for memory T cell establishment. Next, in vivo, OBP-702 local treatment to murine pancreatic PAN02 tumors increased TEMps via ATP induction from tumors and IL-15Rƒ¿ induction from macrophages, leading to TRM and TEM induction. Activation of these memory T cells by OBP-702 was also maintained in combination with gemcitabine+nab-paclitaxel (GN) in a PAN02 bilateral tumor model, and GN?+?OBP-702 showed significant anti-tumor effects and increased TRMs in OBP-702-uninjected tumors. Finally, in a neoadjuvant model, in which PAN02 cells were re-inoculated after resection of treated-PAN02 tumors, GN?+?OBP-702 provided long-term anti-tumor effects even after tumor resection.
Conclusion: OBP-702 can be a long-term immunostimulant with sustained anti-tumor effects on immunologically cold pancreatic cancer. en-copyright= kn-copyright= en-aut-name=HashimotoMasashi

kn-title=International Trends in Adverse Drug Event-Related Mortality from 2001 to 2019: An Analysis of the World Health Organization Mortality Database from 54 Countries en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Objective
Adverse drug events (ADEs) are becoming a significant public health issue. However, reports on ADE-related mortality are limited to national-level evaluations. Therefore, we aimed to reveal overall trends in ADE-related mortality across the 21st century on an international level.
Methods
This observational study analysed long-term trends in ADE-related mortality rates from 2001 to 2019 using the World Health Organization Mortality Database. The rates were analysed according to sex, age and region. North America, Latin America and the Caribbean, Western Europe, Eastern Europe and Western Pacific regions were assessed. Fifty-four countries were included with four-character International Statistical Classification of Disease and Related Health Problems, Tenth Revision codes in the database, population data in the World Population Prospects 2019 report, mortality data in more than half of the study period, and high-quality or medium-quality death registration data. A locally weighted regression curve was used to show international trends in age-standardised rates.
Results
The global ADE-related mortality rate per 100,000 population increased from 2.05 (95% confidence interval 0.92?3.18) in 2001 to 6.86 (95% confidence interval 5.76?7.95) in 2019. Mortality rates were higher among men than among women, especially in those aged 20?50 years. The population aged ??75 years had higher ADE-related mortality rates than the younger population. North America had the highest mortality rate among the five regions. The global ADE-related mortality rate increased by approximately 3.3-fold from 2001 to 2019.
Conclusions
The burden of ADEs has increased internationally with rising mortality rates. Establishing pharmacovigilance systems can facilitate efforts to reduce ADE-related mortality rates globally. en-copyright= kn-copyright= en-aut-name=KoyamaToshihiro en-aut-sei=Koyama en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IinumaShunya en-aut-sei=Iinuma en-aut-mei=Shunya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamamotoMichio en-aut-sei=Yamamoto en-aut-mei=Michio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NiimuraTakahiro en-aut-sei=Niimura en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OsakiYuka en-aut-sei=Osaki en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishimuraSayoko en-aut-sei=Nishimura en-aut-mei=Sayoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HaradaKo en-aut-sei=Harada en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Human Sciences, Osaka University, Osaka, Japan RIKEN Center for Advanced Intelligence Project, kn-affil= affil-num=4 en-affil=Department of Clinical Pharmacology and Therapeutics, Institute of Biomedical Sciences, Tokushima University Graduate School kn-affil= affil-num=5 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Medicine, Icahn School of Medicine at Mount Sinai, Mount Sinai Beth Israel kn-affil= affil-num=8 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=24 article-no= start-page=3619 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231207 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characteristic Mean Kurtosis Values in Simple Diffusion Kurtosis Imaging of Dentigerous Cysts en-subtitle= kn-subtitle= en-abstract= kn-abstract=We evaluated the usefulness of simple diffusion kurtosis (SD) imaging, which was developed to generate diffusion kurtosis images simultaneously with an apparent diffusion coefficient (ADC) map for 27 cystic disease lesions in the head and neck region. The mean kurtosis (MK) and ADC values were calculated for the cystic space. The MK values were dentigerous cyst (DC): 0.74, odontogenic keratocyst (OKC): 0.86, ranula (R): 0.13, and mucous cyst (M): 0, and the ADC values were DC: 1364 ~ 10?6 mm2/s, OKC: 925 ~ 10?6 mm2/s, R: 2718 ~ 10?6 mm2/s, and M: 2686 ~ 10?6 mm2/s. The MK values of DC and OKC were significantly higher than those of R and M, whereas their ADC values were significantly lower. One reason for the characteristic signal values in diffusion-weighted images of DC may be related to content components such as fibrous tissue and exudate cells. When imaging cystic disease in the head and neck region using SD imaging, the maximum b-value setting at the time of imaging should be limited to approximately 1200 s/mm2 for accurate MK value calculation. This study is the first to show that the MK values of DC are characteristically higher than those of other cysts. en-copyright= kn-copyright= en-aut-name=FukumuraYuka en-aut-sei=Fukumura

en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: This research investigated treatment patterns for out-of-hospital cardiac arrest patients with Do Not Attempt Resuscitation orders in Japanese emergency departments and the associated clinician stress.
Methods: A cross-sectional survey was conducted at 9 hospitals in Okayama, Japan, targeting emergency department nurses and physicians. The questionnaire inquired about the last treated out-of-hospital cardiac arrest patient with a Do Not Attempt Resuscitation. We assessed emotional stress on a 0?10 scale and moral distress on a 1?5 scale among clinicians.
Results: Of 208 participants, 107 (51%) had treated an out-of-hospital cardiac arrest patient with a Do Not Attempt Resuscitation order in the past 6 months. Of these, 65 (61%) clinicians used a gslow codeh due to perceived futility in resuscitation (42/65 [65%]), unwillingness to terminate resuscitation upon arrival (38/65 [59%]), and absence of family at the time of patientfs arrival (35/65 [54%]). Female clinicians had higher emotional stress (5 vs. 3; P = 0.007) and moral distress (3 vs. 2; P = 0.002) than males. Nurses faced more moral distress than physicians (3 vs. 2; P < 0.001). Adjusted logistic regression revealed that having performed a gslow codeh (adjusted odds ratio, 5.09 [95% CI, 1.68?17.87]) and having greater ethical concerns about gslow codeh (adjusted odds ratio, 0.35 [95% CI, 0.19?0.58]) were associated with high stress levels.
Conclusions: The prevalent use of gslow codeh for out-of-hospital cardiac arrest patients with Do Not Attempt Resuscitation orders underscores the challenges in managing these patients in clinical practice. en-copyright= kn-copyright= en-aut-name=TanabeRyo en-aut-sei=Tanabe en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ElmerJonathan en-aut-sei=Elmer en-aut-mei=Jonathan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Emergency Medicine, University of Pittsburgh kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Do not attempt resuscitation kn-keyword=Do not attempt resuscitation en-keyword=Out-of-hospital cardiac arrest kn-keyword=Out-of-hospital cardiac arrest en-keyword=Emergency department kn-keyword=Emergency department en-keyword=Clinicians kn-keyword=Clinicians en-keyword=Slow code kn-keyword=Slow code en-keyword=Stress kn-keyword=Stress END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue=1 article-no= start-page=35 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Current status and challenges of breast cancer prevention?DNA methylation would lead to groundbreaking progress in breast cancer prevention? en-subtitle= kn-subtitle= en-abstract= kn-abstract=The number of breast cancer patients is increasing worldwide. Furthermore, breast cancer often develops in young people, even those only in their 30s, who play a central role in their families and society. Results from many cohort studies suggest that dietary factors, alcohol consumption, lack of physical activity, obesity, nulliparity, breastfeeding, oral contraceptive use, fertility treatment and hormone replacement therapy are risk factors for breast cancer. However, the effects of lifestyle habits on the human body are complexly intertwined with various factors, and the effects vary from person to person depending on their constitution, etc., so there is no basis for this. Therefore, primary prevention of breast cancer is still not being implemented appropriately and efficiently. Furthermore, advances in genomic technology make it possible to assess the risk of developing breast cancer in some individuals. As a result, the establishment of breast cancer prevention methods has become a health priority for high-risk individuals. Drugs such as tamoxifen and raloxifene are known to prevent the development of breast cancer, based on the results of multiple randomized controlled trials, but there are concerns regarding the side effects of these powerful agents. In addition, several clinical studies have shown that prophylactic mastectomy for women who have BRCA mutations or who are identified as being at high risk reduces the incidence of breast cancer development. However, many issues, such as changes in long-term quality of life after preventive surgery, the optimal timing of surgery and the identification of women who are at high risk but will not develop breast cancer, remain uncertain. In other words, although many researchers have focused on chemoprevention and surgical prevention and clear preventive effects of these strategies have been confirmed, it cannot be said that they are widely accepted. Therefore, the current evidence for chemoprevention and surgical prevention, as well as highlights of several interesting lines of research currently underway, are summarized in this article. en-copyright= kn-copyright= en-aut-name=TsukiokiTakahiro en-aut-sei=Tsukioki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KhanSeema A. en-aut-sei=Khan en-aut-mei=Seema A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShienTadahiko en-aut-sei=Shien en-aut-mei=Tadahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Breast and Endocrine Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Surgery, Feinberg School of Medicine of Northwestern University kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Breast and Endocrine Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Breast cancer kn-keyword=Breast cancer en-keyword=Prevention kn-keyword=Prevention en-keyword=Risk reduction mastectomy kn-keyword=Risk reduction mastectomy en-keyword=Chemoprevention kn-keyword=Chemoprevention en-keyword=Methylation kn-keyword=Methylation END start-ver=1.4 cd-journal=joma no-vol=127 cd-vols= no-issue=5 article-no= start-page=1398 end-page=1406 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220509 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tactile angle discriminability improvement: contributions of working memory training and continuous attended sensory input en-subtitle= kn-subtitle= en-abstract= kn-abstract=Perceptual learning is commonly assumed to enhance perception through continuous attended sensory input. However, learning is generalizable to performance in untrained stimuli and tasks. Although previous studies have observed a possible generalization effect across tasks as a result of working memory (WM) training, comparisons of the contributions of WM training and continuous attended sensory input to perceptual learning generalization are still rare. Therefore, we compared which factors contributed most to perceptual generalization and investigated which skills acquired during WM training led to tactile generalization across tasks. Here, a Braille-like dot pattern matching n-back WM task was used as the WM training task, with four workload levels (0, 1, 2, and 3-back levels). A tactile angle discrimination (TAD) task was used as a pre- and posttest to assess improvements in tactile perception. Between tests, four subject groups were randomly assigned to four different workload n-back tasks to consecutively complete three sessions of training. The results showed that tactile n-back WM training could enhance TAD performance, with the 3-back training group having the highest TAD threshold improvement rate. Furthermore, the rate of WM capacity improvement on the 3-back level across training sessions was correlated with the rate of TAD threshold improvement. These findings suggest that continuous attended sensory input and enhanced WM capacity can lead to improvements in TAD ability, and that greater improvements in WM capacity can predict greater improvements in TAD performance.
NEW & NOTEWORTHY Perceptual learning is not always specific to the trained task and stimuli. We demonstrate that both continuous attended sensory input and improved WM capacity can be used to enhance tactile angle discrimination (TAD) ability. Moreover, WM capacity improvement is important in generalizing the training effect to the TAD ability. These findings contribute to understanding the mechanism of perceptual learning generalization across tasks. en-copyright= kn-copyright= en-aut-name=WangWu en-aut-sei=Wang en-aut-mei=Wu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YangJiajia en-aut-sei=Yang en-aut-mei=Jiajia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YuYinghua en-aut-sei=Yu en-aut-mei=Yinghua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LiHuazhi en-aut-sei=Li en-aut-mei=Huazhi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=LiuYulong en-aut-sei=Liu en-aut-mei=Yulong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YuYiyang en-aut-sei=Yu en-aut-mei=Yiyang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YuJiabin en-aut-sei=Yu en-aut-mei=Jiabin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TangXiaoyu en-aut-sei=Tang en-aut-mei=Xiaoyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YangJingjing en-aut-sei=Yang en-aut-mei=Jingjing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakahashiSatoshi en-aut-sei=Takahashi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=EjimaYoshimichi en-aut-sei=Ejima en-aut-mei=Yoshimichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=WuJinglong en-aut-sei=Wu en-aut-mei=Jinglong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=School of Psychological and Cognitive Sciences, Peking University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=7 en-affil=College of Information Engineering, China Jiliang University kn-affil= affil-num=8 en-affil=School of Psychology, Liaoning Collaborative Innovation Center of Children and Adolescents Healthy Personality Assessment and Cultivation, Liaoning Normal University kn-affil= affil-num=9 en-affil=School of Computer Science and Technology, Changchun University of Science and Technology kn-affil= affil-num=10 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=12 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=continuous attended sensory input kn-keyword=continuous attended sensory input en-keyword=perceptual learning kn-keyword=perceptual learning en-keyword=tactile angle discriminability kn-keyword=tactile angle discriminability en-keyword=tactile generalization kn-keyword=tactile generalization en-keyword=working memory training kn-keyword=working memory training END start-ver=1.4 cd-journal=joma no-vol=240 cd-vols= no-issue=3 article-no= start-page=773 end-page=789 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220116 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Global surface features contribute to human haptic roughness estimations en-subtitle= kn-subtitle= en-abstract= kn-abstract=Previous studies have paid special attention to the relationship between local features (e.g., raised dots) and human roughness perception. However, the relationship between global features (e.g., curved surface) and haptic roughness perception is still unclear. In the present study, a series of roughness estimation experiments was performed to investigate how global features affect human roughness perception. In each experiment, participants were asked to estimate the roughness of a series of haptic stimuli that combined local features (raised dots) and global features (sinusoidal-like curves). Experiments were designed to reveal whether global features changed their haptic roughness estimation. Furthermore, the present study tested whether the exploration method (direct, indirect, and static) changed haptic roughness estimations and examined the contribution of global features to roughness estimations. The results showed that sinusoidal-like curved surfaces with small periods were perceived to be rougher than those with large periods, while the direction of finger movement and indirect exploration did not change this phenomenon. Furthermore, the influence of global features on roughness was modulated by local features, regardless of whether raised-dot surfaces or smooth surfaces were used. Taken together, these findings suggested that an objectfs global features contribute to haptic roughness perceptions, while local features change the weight of the contribution that global features make to haptic roughness perceptions. en-copyright= kn-copyright= en-aut-name=LiHuazhi en-aut-sei=Li en-aut-mei=Huazhi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YangJiajia en-aut-sei=Yang en-aut-mei=Jiajia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YuYinghua en-aut-sei=Yu en-aut-mei=Yinghua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangWu en-aut-sei=Wang en-aut-mei=Wu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=LiuYulong en-aut-sei=Liu en-aut-mei=Yulong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ZhouMengni en-aut-sei=Zhou en-aut-mei=Mengni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=LiQingqing en-aut-sei=Li en-aut-mei=Qingqing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YangJingjing en-aut-sei=Yang en-aut-mei=Jingjing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShaoShiping en-aut-sei=Shao en-aut-mei=Shiping kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakahashiSatoshi en-aut-sei=Takahashi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=EjimaYoshimichi en-aut-sei=Ejima en-aut-mei=Yoshimichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=WuJinglong en-aut-sei=Wu en-aut-mei=Jinglong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=School of Psychological and Cognitive Sciences, Peking University kn-affil= affil-num=5 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=7 en-affil=Department of Teacher Education, Wenzhou University kn-affil= affil-num=8 en-affil=School of Computer Science and Technology, Changchun University of Science and Technology kn-affil= affil-num=9 en-affil=School of Social Welfare, Yonsei University kn-affil= affil-num=10 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=12 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Haptic roughness perception kn-keyword=Haptic roughness perception en-keyword=Raised-dot surface kn-keyword=Raised-dot surface en-keyword=Local feature kn-keyword=Local feature en-keyword=Global feature kn-keyword=Global feature END start-ver=1.4 cd-journal=joma no-vol=66 cd-vols= no-issue=1 article-no= start-page=31 end-page=44 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Game positions of multiple hook removing game en-subtitle= kn-subtitle= en-abstract= kn-abstract=Multiple Hook Removing Game (MHRG for short) introduced in [1] is an impartial game played in terms of Young diagrams.

Methods@Thirty patients who underwent pullout repair for MM posterior root tear and were evaluated for quadriceps muscle strength preoperatively and at 1 year postoperatively were included in this study. Quadriceps muscle strength was measured using the Locomo Scan-II instrument (ALCARE, Tokyo, Japan). MME and clinical scores (i.e., Knee Injury and Osteoarthritis Outcome Score [KOOS], International Knee Documentation Committee score, Lysholm score, Tegner score, and visual analog scale pain score) were evaluated preoperatively and at 1 year postoperatively, and second-look arthroscopy was performed at 1 year postoperatively. Wilcoxon ' s signed-rank test was used to compare each measure pre-and postoperatively. Pearson ' s correlation coefficient was used to assess the correlation with quadriceps muscle strength values. Multiple regression analysis was performed to identify factors associated with the change in MME (.MME).
Results@Second-look arthroscopy confirmed continuity of the posterior root in all patients. The quadriceps muscle strength measured at 1 year postoperatively (355.1 +/- 116.2 N) indicated significant improvement relative to the quadriceps muscle strength measured preoperatively (271.9 +/- 97.4 N, p < 0.001). The MME at 1 year postoperatively (4.59 +/- 1.24 mm) had progressed significantly relative to the MME preoperatively (3.63 +/- 1.01 mm, p < 0.001). The clinical scores at 1 year postoperatively were improved significantly relative to the scores preoperatively (p < 0.001). The postoperative quadriceps muscle strength was correlated with.MME (correlation coefficient = -0.398, p = 0.030), and the change in quadriceps muscle strength was correlated with the KOOS-Quality of Life (correlation coefficient = 0.430, p = 0.018). Multiple regression analysis showed that the postoperative quadriceps muscle strength had a significant effect on.MME even when the body mass index and time from injury to surgery were included.
Conclusions@After MM posterior root repair, patients with greater quadriceps muscle strength showed less MME progression. In addition, patients with greater improvement in quadriceps muscle strength had better clinical scores; therefore, continued rehabilitation aimed at improving quadriceps muscle strength after MM posterior root repair is recommended. en-copyright= kn-copyright= en-aut-name=KawadaKoki en-aut-sei=Kawada en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukubaMikao en-aut-sei=Fukuba en-aut-mei=Mikao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TamuraMasanori en-aut-sei=Tamura en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HigashiharaNaohiro en-aut-sei=Higashihara en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YokoyamaYusuke en-aut-sei=Yokoyama en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KatayamaYoshimi en-aut-sei=Katayama en-aut-mei=Yoshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HamadaMasanori en-aut-sei=Hamada en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Clinical score kn-keyword=Clinical score en-keyword=Medial meniscus kn-keyword=Medial meniscus en-keyword=Medial meniscus extrusion kn-keyword=Medial meniscus extrusion en-keyword=Muscle strength kn-keyword=Muscle strength en-keyword=Posterior root tear kn-keyword=Posterior root tear en-keyword=Quadriceps kn-keyword=Quadriceps END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=5 article-no= start-page=471 end-page=478 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Low Patient Weight and Long Intubation Time Are Key Factors for Pain during Colonoscopy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although the clinical usefulness of colonoscopy has been established, the procedure remains painful for many patients. This study was designed to clarify the factors predicting colonoscopy-related pain. We evaluated 283 consecutive patients who completed a first-ever, total colonoscopy without sedatives or analgesics. The severity of pain symptoms was evaluated by a numeric rating scale (NRS) in a questionnaire immediately after the colonoscopy. Patient backgrounds and endoscopic findings were analyzed to evaluate their association with pain. Out of 283 patients, 53 scored their pain 0-1 on the NRS while 48 scored it 6-10. We defined the colonoscopies of the former and latter patients as painless and painful, respectively, and compared the two. Multivariate analyses revealed that low body weight (OR 4.95, 95%CI 1.89-12.99) and longer intubation time (OR 3.63, 95%CI 1.46-9.03) were significant risk factors for painful colonoscopy. To identify factors contributing to the increased intubation time, we divided subjects into short- and long-intubation-time groups based on a median insertion time of 7 min. Older age (OR 2.28, 95%CI 1.31-3.98), previous abdominal surgery (OR 1.93, 95%CI 1.13-3.32) and findings of invasive cancer (OR 10.90, 95%CI 1.34-88.90) were significant factors for longer intubation time. en-copyright= kn-copyright= en-aut-name=OkaShohei en-aut-sei=Oka en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HaradaKeita en-aut-sei=Harada en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamamotoShumpei en-aut-sei=Yamamoto en-aut-mei=Shumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasutomiEriko en-aut-sei=Yasutomi en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IgawaShoko en-aut-sei=Igawa en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhmoriMasayasu en-aut-sei=Ohmori en-aut-mei=Masayasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HiraiMami en-aut-sei=Hirai en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamasakiYasushi en-aut-sei=Yamasaki en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=InokuchiToshihiro en-aut-sei=Inokuchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KinugasaHideaki en-aut-sei=Kinugasa en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TakaharaMasahiro en-aut-sei=Takahara en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=colonoscopy kn-keyword=colonoscopy en-keyword=colonoscopy-related pain kn-keyword=colonoscopy-related pain en-keyword=comfortable colonoscopy kn-keyword=comfortable colonoscopy END start-ver=1.4 cd-journal=joma no-vol=42 cd-vols= no-issue=6 article-no= start-page=698 end-page=708 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230922 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Investigating the Effect of Substituting a Single Cysteine Residue on the Thermal Stability of an Engineered Sweet Protein, Single-Chain Monellin en-subtitle= kn-subtitle= en-abstract= kn-abstract=Single-chain monellin (SCM) is an engineered protein that links the two chains of monellin, a naturally sweet-tasting protein. This protein is an attractive candidate for use as a sugar replacement in food and beverages and has numerous other applications. Therefore, generating SCM mutants with improved stability is an active area of research to broaden the range of its potential applications. In this study, we focused on the Cys41 residue of SCM, which is a single cysteine residue present at a structurally important position. This residue is often substituted with Ser. However, this substitution may destabilize SCM because Cys41 is buried in the hydrophobic core of the protein. Therefore, we designed mutants that substituted Ala, Val, and Leu for this residue, namely C41A, C41V, and C41L. We characterized these three mutants, SCM C41S, and wild type (WT). Differential scanning fluorimetric analysis revealed that substituting Cys41 with Ala or Val increased the thermal stability of SCM, while substitution with Ser or Leu decreased its stability. Determination of the crystal structures of SCM C41A and C41V mutants revealed that the overall structures and main chain structures around the 41st residue of both mutants were almost identical to the WT. On the other hand, the orientations of the amino acid side chains near the 41st residue differed among the SCM variants. Taken together, our results indicate that substituting Cys41 with Ala or Val increases the stability of SCM and provide insight into the structural basis of this improvement. en-copyright= kn-copyright= en-aut-name=OhnumaKyosuke en-aut-sei=Ohnuma en-aut-mei=Kyosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamashitaAtsuko en-aut-sei=Yamashita en-aut-mei=Atsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuiNorihisa en-aut-sei=Yasui en-aut-mei=Norihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=School of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=School of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=School of Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Crystallography kn-keyword=Crystallography en-keyword=Monellin kn-keyword=Monellin en-keyword=Protein Stability kn-keyword=Protein Stability en-keyword=Recombinant Proteins kn-keyword=Recombinant Proteins END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=1 article-no= start-page=e000772 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220927 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association of one-point glucocorticoid-free status with chronic damage and disease duration in systemic lupus erythematosus: a cross-sectional study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective@It is still unclear how glucocorticoids (GCs) affect the long-term clinical course of patients with SLE. The objective of this study is to explore the factors associated with GC-free treatment status.
Methods@Using data from the lupus registry of nationwide institutions, GC dose at registration was compared between short, middle and long disease durations of <5, 5?20 and ?20 years, respectively. After excluding patients who never used GC, we evaluated the relationship between GC-free status and chronic damage using Systemic Lupus International Collaborating Clinics Damage Index.
Results@GC doses at enrolment of the 1019 patients were as follows: GC-free in 101 (10%); 0 Conclusion@Even in the patients with long disease duration, one-point GC-free treatment status might be related to no chronic damage accrual. en-copyright= kn-copyright= en-aut-name=SadaKen-ei en-aut-sei=Sada en-aut-mei=Ken-ei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

durable flame-retardant, were prepared by the successive treatment of ArOH (Ar = BrnC6H5?n, n = 0, 1, 2, and 3) with POCl3 and melamine monomer. The prepared flame-retardants were grafted through the CH2 unit to lignocellulose nanofibers (LCNFs) by the Mannich reaction. The resulting three-component products were characterized using FT-IR (ATR) and EA. The thermal behavior of the NPCM-treated LCNF fabric samples was determined using TGA and DSC analyses, and their flammability resistances were evaluated by measuring their Limited Oxygen Index (LOI) and the UL-94V test. A multitude of flame retardant elements in the fabric samples increased the LOI values as much as 45 from 20 of the untreated LCNFs. Moreover, the morphology of both the NPCM-treated LCNFs and their burnt fabrics was studied with a scanning electron microscope (SEM). The heat release lowering effect of the LCNF fabric against the water-based paint was observed with a cone calorimeter. Furthermore, the mechanical properties represented as the tensile strength of the NPCM-treated LCNF fabrics revealed that the increase of the NPCM content in the PP-composites led to an increased bending strength with enhancing the flame-retardance. en-copyright= kn-copyright= en-aut-name=OnoFumiaki en-aut-sei=Ono en-aut-mei=Fumiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkiharaTakumi en-aut-sei=Okihara en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OsakaNoboru en-aut-sei=Osaka en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NagaokaNoriyuki en-aut-sei=Nagaoka en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KameokaYuji en-aut-sei=Kameoka en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IshikawaAkira en-aut-sei=Ishikawa en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OokiHironari en-aut-sei=Ooki en-aut-mei=Hironari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ItoTakumi en-aut-sei=Ito en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TodomeDaisuke en-aut-sei=Todome en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=UemotoShinya en-aut-sei=Uemoto en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FurutaniMitsuaki en-aut-sei=Furutani en-aut-mei=Mitsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=InokuchiTsutomu en-aut-sei=Inokuchi en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OkadaKenji en-aut-sei=Okada en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Okayama Biomass Innovation Creative Center kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Science, Okayama University of Science kn-affil= affil-num=4 en-affil=Advanced Research Center for Oral and Craniofacial Science, Okayama University Dental School kn-affil= affil-num=5 en-affil=Marubishi Oil Chemical Co., Ltd kn-affil= affil-num=6 en-affil=Marubishi Oil Chemical Co., Ltd kn-affil= affil-num=7 en-affil=Gen Gen Corporation kn-affil= affil-num=8 en-affil=Gen Gen Corporation kn-affil= affil-num=9 en-affil=Faculty of Science, Okayama University of Science kn-affil= affil-num=10 en-affil=Okayama Biomass Innovation Creative Center kn-affil= affil-num=11 en-affil=Okayama Biomass Innovation Creative Center kn-affil= affil-num=12 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=13 en-affil=Department of Life Science, Kurashiki University of Science & the Arts kn-affil= END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=3 article-no= start-page=423 end-page=431 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211115 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The number of circulating CD34-positive cells is an independent predictor of coronary artery calcification progression: Sub-analysis of a prospective multicenter study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Decreases in circulating CD34-positive cells are associated with increases in cardiovascular events. We investigated the association between the number of CD34-positive cells and the progression of coronary artery calcification (CAC), a marker of atherosclerosis, in patients with hypercholesteremia under statin therapy in a sub-analysis of a multicenter study.
Methods: In the principal study, patients with CAC scores of 1?999 were treated with pitavastatin. Measurement of CAC by non-enhanced computed tomography and a blood test were performed at baseline and at 1-year follow-up. Patients were divided into two groups: CAC progression (change in CAC score > 0) and non-progression. The number of circulating CD34-positive cells was counted using flow cytometry.
Results: A total of 156 patients (mean age 67 years, 55% men) were included in this sub-analysis. CD34 positive cell numbers at baseline as a continuous variable was inversely correlated with annual change in the log-transformed CAC score (r = ?0.19, p = 0.02). When patients were divided into high and low CD34 groups based on the median value of 0.8 cells/ƒÊL, the adjusted change in CAC score in the low-CD34 group was significantly greater than that in the high-CD34 group (54.2% vs. 20.8%, respectively, p = 0.04). In multiple logistic analysis, a low CD34-positive cell number was an independent predictor of CAC progression, with an odds ratio of 2.88 (95% confidence interval 1.28?6.49, p = 0.01).
Conclusions: Low numbers of CD34-positive cells are associated with CAC progression in patients with hypercholesterolemia under statin therapy. The number of CD34-positive cells may help to identify patients at increased cardiovascular risk. en-copyright= kn-copyright= en-aut-name=IchikawaKeishi en-aut-sei=Ichikawa en-aut-mei=Keishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OsawaKazuhiro en-aut-sei=Osawa en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MikiTakashi en-aut-sei=Miki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KohnoKunihisa en-aut-sei=Kohno en-aut-mei=Kunihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KoyamaYasushi en-aut-sei=Koyama en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Density and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Density and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Japanese Red Cross Okayama Hospital kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Density and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Density and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Density and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Cardiology, Sakurabashi Watanabe Hospital kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Density and Pharmaceutical Sciences kn-affil= en-keyword=coronary artery calcification kn-keyword=coronary artery calcification en-keyword=computed tomography kn-keyword=computed tomography en-keyword=endothelial progenitor cells kn-keyword=endothelial progenitor cells en-keyword=hypercholesterolemia kn-keyword=hypercholesterolemia END start-ver=1.4 cd-journal=joma no-vol=40 cd-vols= no-issue=10 article-no= start-page=1024 end-page=1034 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220702 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Up-to-date evidence on image-guided thermal ablation for metastatic lung tumors: a review en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this review was to summarize the latest evidence on image-guided thermal ablation therapies for lung metastases. PubMed was used to search for relevant articles that reported the oncological outcomes of thermal ablation for metastatic lung tumors, and those published in 2010 or later were selected for review. Ablative therapies were applied for lung metastases from various types of primary tumors, but most commonly colorectal ones. Radiofrequency ablation (RFA) was the most evaluated technique, followed by microwave ablation (MWA). The local control rates of ablative therapies were generally favorable, approximately 80?90% in many studies. Representative studies demonstrated promising overall survival rates of approximately 50% or higher 5 years after ablation for lung metastases from colorectal cancer or mixed types of primary tumors. Nevertheless, the survival outcomes varied depending on the type of primary tumor and background factors of patients such as other metastases and comorbidities. Several studies had aimed to compare the outcomes of various ablative therapies such as RFA, MWA, and cryoablation; however, conclusive data are not yet available to determine the most appropriate ablation modality for lung metastases. Further data accumulation is needed, especially for long-term outcomes and comparisons with other therapies. en-copyright= kn-copyright= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TomitaKoji en-aut-sei=Tomita en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UkaMayu en-aut-sei=Uka en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UmakoshiNoriyuki en-aut-sei=Umakoshi en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawabataTakahiro en-aut-sei=Kawabata en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MunetomoKazuaki en-aut-sei=Munetomo en-aut-mei=Kazuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NagataShoma en-aut-sei=Nagata en-aut-mei=Shoma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Ablation kn-keyword=Ablation en-keyword=Lung kn-keyword=Lung en-keyword=Pulmonary kn-keyword=Pulmonary en-keyword=Metastasis kn-keyword=Metastasis END start-ver=1.4 cd-journal=joma no-vol=34 cd-vols= no-issue=1 article-no= start-page=67 end-page=74 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Detailed Anatomy of Bridging Veins Around the Foramen Magnum: a?Multicenter Study Using Three-dimensional Angiography en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Purpose@There has been limited literature regarding the bridging veins (BVs) of the medulla oblongata around the foramen magnum (FM). The present study aims to analyze the normal angioarchitecture of the BVs around the FM using slab MIP images of three-dimensional (3D) angiography.
Methods@We collected 3D angiography data of posterior fossa veins and analyzed the BVs around the FM using slab MIP images. We analyzed the course, outlet, and number of BVs around the FM. We also examined the detection rate and mean diameter of each BV.
Results@Of 57 patients, 55 patients (96%) had any BV. The median number of BVs was two (range: 0?5). The BVs originate from the perimedullary veins and run anterolaterally to join the anterior condylar vein (ACV), inferior petrosal sinus, sigmoid sinus, or jugular bulb, inferolaterally to join the suboccipital cavernous sinus (SCS), laterally or posterolaterally to join the marginal sinus (MS), and posteriorly to join the MS or occipital sinus. We classified BVs into five subtypes according to the draining location: ACV, jugular foramen (JF), MS, SCS, and cerebellomedullary cistern (CMC). ACV, JF, MS, SCS, and CMC BVs were detected in 11 (19%), 18 (32%), 32 (56%), 20 (35%), and 16 (28%) patients, respectively. The mean diameter of the BVs other than CMC was 0.6?mm, and that of CMC BV was 0.8?mm.
Conclusion@Using venous data from 3D angiography, we detected FM BVs in most cases, and the BVs were connected in various directions. en-copyright= kn-copyright= en-aut-name=HiramatsuMasafumi en-aut-sei=Hiramatsu en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OzakiTomohiko en-aut-sei=Ozaki en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanoueShuichi en-aut-sei=Tanoue en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MizutaniKatsuhiro en-aut-sei=Mizutani en-aut-mei=Katsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakamuraHajime en-aut-sei=Nakamura en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TokuyamaKohei en-aut-sei=Tokuyama en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakataHiroyuki en-aut-sei=Sakata en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsumaruYuji en-aut-sei=Matsumaru en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakaharaIchiro en-aut-sei=Nakahara en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NiimiYasunari en-aut-sei=Niimi en-aut-mei=Yasunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FujinakaToshiyuki en-aut-sei=Fujinaka en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KiyosueHiro en-aut-sei=Kiyosue en-aut-mei=Hiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurosurgery, National Hospital Organization, Osaka National Hospital kn-affil= affil-num=3 en-affil=Department of Radiology, Kurume University School of Medicine kn-affil= affil-num=4 en-affil=Department of Neurosurgery, Keio University School of Medicine kn-affil= affil-num=5 en-affil=Department of Neurosurgery, Osaka University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Radiology, Oita University Faculty of Medicine kn-affil= affil-num=7 en-affil=Department of Neuroendovascular Therapy, Kohnan Hospital kn-affil= affil-num=8 en-affil=Division of Stroke Prevention and Treatment, Department of Neurosurgery, Faculty of Medicine, University of Tsukuba kn-affil= affil-num=9 en-affil=Department of Comprehensive Strokology, Fujita Health University School of Medicine kn-affil= affil-num=10 en-affil=Department of Neuroendovascular Therapy, St Lukefs International Hospital kn-affil= affil-num=11 en-affil=Department of Neurosurgery, National Hospital Organization, Osaka National Hospital kn-affil= affil-num=12 en-affil=Department of Diagnostic Radiology, Kumamoto University Faculty of Medicine kn-affil= en-keyword=Bridging vein kn-keyword=Bridging vein en-keyword=Foramen magnum kn-keyword=Foramen magnum en-keyword=Cone-beam CT kn-keyword=Cone-beam CT en-keyword=Venous phase three-dimensional rotational angiography kn-keyword=Venous phase three-dimensional rotational angiography en-keyword=Slab maximum intensity projection kn-keyword=Slab maximum intensity projection en-keyword=Dural arteriovenous fistula kn-keyword=Dural arteriovenous fistula END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=5 article-no= start-page=2178 end-page=2185 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prognostic risk factors for postoperative long-term outcomes in elderly stage IA gastric cancer patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The number of gastric cancer (GC) patients with other diseases is increasing due to the aging of the population. In particular, in stage IA GC patients who have multiple diseases, surgical indications should be considered after identifying prognostic factors. We therefore investigated prognostic factors for stage IA GC in the elderly.
Methods: Patient characteristics were collected and analyzed retrospectively for elderly patients with stage IA GC who underwent curative surgical treatment at Okayama University Hospital between 2010 and 2015, and an elderly group (EG; 75?79 years old) and very elderly group (VEG; ?80 years old) were compared.
Results: Fifty-three patient in the EG and 31 patients in the VEG were compared. No factors associated with clinicopathological characteristics or surgical or postoperative short-term outcomes differed significantly between groups. Although no factors in the EG appeared significantly associated with poor overall survival (OS), severe comorbidity [Charlson Comorbidity Index (CCI) ?2; P=0.019], open gastrectomy (P=0.012), high volume of blood loss (?300 mL; P=0.013) and long postoperative hospital stay (?14 days; P=0.041) were significantly associated with poor OS. Furthermore, only CCI ?2 [hazard ratio (HR) =9.2; 95% confidence interval (CI): 1.2?68.9; P=0.032] was an independent prognostic factor associated with poor OS. Five-year OS was 88.9% for CCI 0/1 patients and 62.3% for CCI ?2 patients, representing very impressive results.
Conclusions: CCI ?2 is an important prognostic factor in clinical decisions in stage IA GC patients ?2, so careful determination of surgical indications is desirable. en-copyright= kn-copyright= en-aut-name=KakiuchiYoshihiko en-aut-sei=Kakiuchi en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KurodaShinji en-aut-sei=Kuroda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KikuchiSatoru en-aut-sei=Kikuchi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KagawaShunsuke en-aut-sei=Kagawa en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Gastric cancer (GC) kn-keyword=Gastric cancer (GC) en-keyword=elderly kn-keyword=elderly en-keyword=stage IA kn-keyword=stage IA en-keyword=comorbidity kn-keyword=comorbidity en-keyword=Charlson comorbidity index (CCI) kn-keyword=Charlson comorbidity index (CCI) END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=37 article-no= start-page=20035 end-page=20047 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220809 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of the rigid and sterically bulky structure of non-fused nonfullerene acceptors on transient photon-to-current dynamics en-subtitle= kn-subtitle= en-abstract= kn-abstract=Non-fused electron-accepting ƒÎ-conjugated compounds have been investigated recently for application to nonfullerene acceptors (NFAs) in organic solar cells (OSCs). However, the establishment of rational molecular design for non-fused NFAs is still lagging because the influence of flexible non-fused structures on the dynamics of electron?hole pairs in OSCs is not entirely understood. In this study, we utilized cyclopentene-annelated thiophene with spiro-substituted 2,7-bis(2-ethylhexyl)fluorene (FT) as a rigid and sterically bulky linker unit and developed a non-fused NFA (TT?FT?DCI) containing FT units. Photophysical measurements indicated that the introduction of the FT unit leads to the formation of rigid molecular structure. OSCs based on donor polymer (PBDB-T) and TT?FT?DCI showed an improved power conversion efficiency of 7.13% due to the increase in the short-circuit current density and fill factor. Time-resolved optical and microwave spectroscopies showed that the FT unit contributes to the long lifetimes of excited state and charge-separated state in the PBDBT:TT?FT?DCI blend films. Time-resolved electron paramagnetic resonance measurements showed that the distant charge-separated states of the face-to-face PBDB-T:TT?FT?DCI structure, which is derived by avoiding over-crystallization by the steric bulkiness of TT?FT?DCI, can interact with the cathodes for preferential electron injection following charge generations. This study highlights that by using the rigid ƒÎ-conjugated framework and suppressed self-aggregation of the non-fused acceptor, effective molecular design for the appropriate dynamics of photocurrent generation is possible. en-copyright= kn-copyright= en-aut-name=JinnaiSeihou en-aut-sei=Jinnai en-aut-mei=Seihou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MurayamaKasumi en-aut-sei=Murayama en-aut-mei=Kasumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NagaiKeisuke en-aut-sei=Nagai en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MineshitaMegumi en-aut-sei=Mineshita en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatoKosaku en-aut-sei=Kato en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MuraokaAzusa en-aut-sei=Muraoka en-aut-mei=Azusa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamakataAkira en-aut-sei=Yamakata en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SaekiAkinori en-aut-sei=Saeki en-aut-mei=Akinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KoboriYasuhiro en-aut-sei=Kobori en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IeYutaka en-aut-sei=Ie en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=The Institute of Scientific and Industrial Research (SANKEN), Osaka University kn-affil= affil-num=2 en-affil=Department of Chemistry, Graduate School of Science, Kobe University kn-affil= affil-num=3 en-affil=The Institute of Scientific and Industrial Research (SANKEN), Osaka University kn-affil= affil-num=4 en-affil=Department of Mathematics, Physics and Computer Science, Japan Women's University kn-affil= affil-num=5 en-affil=Graduate School of Natural Science & Technology, Okayama University kn-affil= affil-num=6 en-affil=Department of Mathematics, Physics and Computer Science, Japan Women's University kn-affil= affil-num=7 en-affil=Graduate School of Natural Science & Technology, Okayama University kn-affil= affil-num=8 en-affil=Department of Applied Chemistry, Graduate School of Engineering, Osaka University kn-affil= affil-num=9 en-affil=Department of Chemistry, Graduate School of Science, Kobe University kn-affil= affil-num=10 en-affil=The Institute of Scientific and Industrial Research (SANKEN), Osaka University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=1 article-no= start-page=825 end-page=846 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230809 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Data-driven evolutionary computation for service constrained inventory optimization in multi-echelon supply chains en-subtitle= kn-subtitle= en-abstract= kn-abstract=Supply chain digital twin has emerged as a powerful tool in studying the behavior of an actual supply chain. However, most studies in the field of supply chain digital twin have only focused on what-if analysis that compares several different scenarios. This study proposes a data-driven evolutionary algorithm to efficiently solve the service constrained inventory optimization problem using historical data that generated by supply chain digital twins. The objective is to minimize the total costs while satisfying the required service level for a supply chain. The random forest algorithm is used to build surrogate models which can be used to estimate the total costs and service level in a supply chain. The surrogate models are optimized by an ensemble approach-based differential evolution algorithm which can adaptively use different search strategies to improve the performance during the computation process. A three-echelon supply chain digital twin on the geographic information system (GIS) map in real-time is used to examine the efficiency of the proposed method. The experimental results indicate that the data-driven evolutionary algorithm can reduce the total costs and maintain the required service level. The finding suggests that our proposed method can learn from the historical data and generate better inventory policies for a supply chain digital twin. en-copyright= kn-copyright= en-aut-name=LiuZiang en-aut-sei=Liu en-aut-mei=Ziang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiTatsushi en-aut-sei=Nishi en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Evolutionary algorithm kn-keyword=Evolutionary algorithm en-keyword=Inventory management kn-keyword=Inventory management en-keyword=Data-driven kn-keyword=Data-driven en-keyword=Supply chain kn-keyword=Supply chain en-keyword=Digital twin kn-keyword=Digital twin END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=4 article-no= start-page=371 end-page=375 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relationship between the Arthroscopic Findings and Pathology of Greater Trochanteric Pain Syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=In recent publications on greater trochanteric pain syndrome (GTPS), the pathology receiving the most attention has been gluteus medius muscle tendinous injury, and surgical techniques such as gluteus medius tendon repair and their outcomes for GTPS have been reported. In our department-related facilities, arthroscopic surgeries are routinely performed for the patients with recalcitrant GTPS. A total of 51 patients were diagnosed with GTPS. Surgical treatment was carried out 22 patients (24 joints; 4 males and 18 females; mean age at surgery of 52.0 years). Arthroscopic findings confirmed bursitis in all 24 joints. In all cases, debridement of the greater trochanter bursa provided rapid relief of greater trochanter pain. The Numerical Rating Scale showed significant improvement, from the preoperative mean of 7.8 (range, 6-10) to the postoperative day 7 mean of 1.6 (range, 0-3). The modified Harris Hip Score was significantly improved from the preoperative mean of 65.5 (range, 52.5-78.3) to the final follow-up (average 2.9 months) mean of 96.0 (range, 85.2-100). Fascial damage of the gluteus medius muscle was observed in 21 joints while only 2 patients had a gluteus medius tendinous injury. Greater trochanteric bursitis and fascia or muscle-fiber injury of the gluteus medius muscle are the most common pathologies in patients with lateral hip pain. en-copyright= kn-copyright= en-aut-name=IwamotoYosuke en-aut-sei=Iwamoto en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KayaMitsunori en-aut-sei=Kaya en-aut-mei=Mitsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KijimaHiroaki en-aut-sei=Kijima en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiiMasashi en-aut-sei=Fujii en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NagahataItsuki en-aut-sei=Nagahata en-aut-mei=Itsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyakoshiNaohisa en-aut-sei=Miyakoshi en-aut-mei=Naohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Kaya Orthopedic Surgery Sports Clinic kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Akita Hip Research Group kn-affil= affil-num=5 en-affil=Akita Hip Research Group kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= en-keyword=greater trochanteric pain syndrome kn-keyword=greater trochanteric pain syndrome en-keyword=endoscopic findings kn-keyword=endoscopic findings en-keyword=bursitis kn-keyword=bursitis END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=3 article-no= start-page=657 end-page=666 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221207 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Important roles of odontoblast membrane phospholipids in early dentin mineralization en-subtitle= kn-subtitle= en-abstract= kn-abstract=The objective of this study was to first identify the timing and location of early mineralization of mouse first molar, and subsequently, to characterize the nucleation site for mineral formation in dentin from a materials science viewpoint and evaluate the effect of environmental cues (pH) affecting early dentin formation. Early dentin mineralization in mouse first molars began in the buccal central cusp on post-natal day 0 (P0), and was first hypothesized to involve collagen fibers. However, elemental mapping indicated the co-localization of phospholipids with collagen fibers in the early mineralization area. Co-localization of phosphatidylserine and annexin V, a functional protein that binds to plasma membrane phospholipids, indicated that phospholipids in the pre-dentin matrix were derived from the plasma membrane. A 3-dimensional in vitro biomimetic mineralization assay confirmed that phospholipids from the plasma membrane are critical factors initiating mineralization. Additionally, the direct measurement of the tooth germ pH, indicated it to be alkaline. The alkaline environment markedly enhanced the mineralization of cell membrane phospholipids. These results indicate that cell membrane phospholipids are nucleation sites for mineral formation, and could be important materials for bottom-up approaches aiming for rapid and more complex fabrication of dentin-like structures. en-copyright= kn-copyright= en-aut-name=AnadaRisa en-aut-sei=Anada en-aut-mei=Risa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HaraEmilio Satoshi en-aut-sei=Hara en-aut-mei=Emilio Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NagaokaNoriyuki en-aut-sei=Nagaoka en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkadaMasahiro en-aut-sei=Okada en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KamiokaHiroshi en-aut-sei=Kamioka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsumotoTakuya en-aut-sei=Matsumoto en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Advanced Research Center for Oral and Craniofacial Sciences, Dental School, Okayama University kn-affil= affil-num=4 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=34 cd-vols= no-issue=1 article-no= start-page=39 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221008 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical evaluation of suture materials for transtibial pullout repair of medial meniscus posterior root tear en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: There are no recommendations for specific suture materials in transtibial pullout repair of medial meniscus posterior root tears. This study aimed to evaluate the clinical outcomes of transtibial pullout repair of medial meniscus posterior root tears using ultrahigh-molecular-weight polyethylene sutures and suture tape.
Methods: We retrospectively reviewed the data of 36 patients (27 women and 9 men, mean age 64.1 years) who had undergone transtibial pullout repair of medial meniscus posterior root tears between November 2018 and December 2019. Two groups of 18 patients each received either two different cord-like sutures or suture tape. Clinical parameters were assessed preoperatively and on second-look arthroscopy (mean postoperative period 12 months). The meniscal healing status was assessed using a previously published scoring system (ranging from 0 to 10), and the incidence rate of suture cut-out was assessed on second-look arthroscopy.
Results: All clinical scores significantly improved in both groups, with no significant between-group differences on second-look arthroscopy. The arthroscopic meniscal healing scores significantly differed between sutures (mean 6.7 points) and suture tape (mean 7.4 points; p?=?0.044). No significant between-group difference in the suture cut-out rate was observed.
Conclusions: This study found no significant differences in the clinical outcomes between ultrahigh-molecular-weight polyethylene sutures and suture tape. Favorable clinical outcomes were obtained using both types of suture; however, the usefulness of suture tape appears to be limited. en-copyright= kn-copyright= en-aut-name=HiranakaTakaaki en-aut-sei=Hiranaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KintakaKeisuke en-aut-sei=Kintaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KamatsukiYusuke en-aut-sei=Kamatsuki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ZhangXiming en-aut-sei=Zhang en-aut-mei=Ximing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=XueHaowei en-aut-sei=Xue en-aut-mei=Haowei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HamadaMasanori en-aut-sei=Hamada en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= en-keyword=Medial meniscus kn-keyword=Medial meniscus en-keyword=Posterior root tear kn-keyword=Posterior root tear en-keyword=Clinical outcome kn-keyword=Clinical outcome en-keyword=Meniscal healing kn-keyword=Meniscal healing en-keyword=Suture material kn-keyword=Suture material en-keyword=Pullout repair kn-keyword=Pullout repair END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=8954 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Refining the evolutionary tree of the horse Y chromosome en-subtitle= kn-subtitle= en-abstract= kn-abstract=The Y chromosome carries information about the demography of paternal lineages, and thus, can prove invaluable for retracing both the evolutionary trajectory of wild animals and the breeding history of domesticates. In horses, the Y chromosome shows a limited, but highly informative, sequence diversity, supporting the increasing breeding influence of Oriental lineages during the last 1500 years. Here, we augment the primary horse Y-phylogeny, which is currently mainly based on modern horse breeds of economic interest, with haplotypes (HT) segregating in remote horse populations around the world. We analyze target enriched sequencing data of 5 Mb of the Y chromosome from 76 domestic males, together with 89 whole genome sequenced domestic males and five Przewalski's horses from previous studies. The resulting phylogeny comprises 153 HTs defined by 2966 variants and offers unprecedented resolution into the history of horse paternal lineages. It reveals the presence of a remarkable number of previously unknown haplogroups in Mongolian horses and insular populations. Phylogenetic placement of HTs retrieved from 163 archaeological specimens further indicates that most of the present-day Y-chromosomal variation evolved after the domestication process that started around 4200 years ago in the Western Eurasian steppes. Our comprehensive phylogeny significantly reduces ascertainment bias and constitutes a robust evolutionary framework for analyzing horse population dynamics and diversity. en-copyright= kn-copyright=

We evaluated epidemiological features of acute MMPRT for its early detection and accurate diagnosis.
Methods@Among 330 MMPRT patients from 2018 to 2020, those who underwent arthroscopic pullout repairs were enrolled. Patients who underwent non-operative treatment or knee arthroplasty, those with a cruciate ligament-deficient knee or advanced osteoarthritis of the knee, and those with insufficient data were excluded. Finally, we retrospectively evaluated data from 234 MMPRTs (female: 79.9%, complete tears: 92.7%, mean age: 65 years). Welchfs t-test and Chi-squared test were used for pairwise comparisons. Spearmanfs rank correlation analysis was performed between age at surgery and body mass index (BMI). Multivariable logistic regression analysis with stepwise backward elimination was applied to the values as risk factors for painful popping events.

Human monocyte chemoattractant protein-1 (MCP-1/CCL2) was isolated from the culture supernatants of not only mitogen-activated peripheral blood mononuclear leukocytes but also malignant glioma cells based on its in vitro chemotactic activity toward human monocytes. MCP-1 was subsequently found to be identical to a previously described tumor cell-derived chemotactic factor thought to be responsible for the accumulation of tumor-associated macrophages (TAMs), and it became a candidate target of clinical intervention; however, the role of TAMs in cancer development was still controversial at the time of the discovery of MCP-1. The in vivo role of MCP-1 in cancer progression was first evaluated by examining human cancer tissues, including breast cancers. Positive correlations between the level of MCP-1 production in tumors and the degree of TAM infiltration and cancer progression were established. The contribution of MCP-1 to the growth of primary tumors and metastasis to the lung, bone, and brain was examined in mouse breast cancer models. The results of these studies strongly suggested that MCP-1 is a promoter of breast cancer metastasis to the lung and brain but not bone. Potential mechanisms of MCP-1 production in the breast cancer microenvironment have also been reported. In the present manuscript, we review studies in which the role of MCP-1 in breast cancer development and progression and the mechanisms of its production were examined and attempt to draw a consensus and discuss the potential use of MCP-1 as a biomarker for diagnosis. en-copyright= kn-copyright= en-aut-name=YoshimuraTeizo en-aut-sei=Yoshimura en-aut-mei=Teizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LiChunning en-aut-sei=Li en-aut-mei=Chunning kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WangYuze en-aut-sei=Wang en-aut-mei=Yuze kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Breast cancer kn-keyword=Breast cancer en-keyword=chemokines kn-keyword=chemokines en-keyword=chemokine receptors kn-keyword=chemokine receptors en-keyword=metastasis kn-keyword=metastasis en-keyword=macrophages kn-keyword=macrophages END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=3 article-no= start-page=291 end-page=299 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Comparison of the Efficacy of Plastic Stent Placement Above and Across the Sphincter of Oddi for Benign Biliary Hilar Stricture en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated the efficacy and safety of endoscopic plastic stent (PS) placement for hilar benign biliary strictures (BBSs) and compared cases with PS placement above (inside stent, IS) and across (usual stent, US) the sphincter of Oddi. Patients who underwent initial endoscopic PS placement for hilar BBSs between August 2012 and December 2021 were retrospectively analyzed. Hilar BBSs in 88 patients were investigated. Clinical success was achieved in 81 of these cases (92.0%), including 38 patients in the IS group and 43 patients in the US group. Unexpected stent exchange (uSE) before the first scheduled PS exchange occurred in 18 cases (22.2%). The median time from first stent placement to uSE was 35 days. There was no significant difference in the rate and median time to uSE between the two groups. The rates of adverse events such as pancreatitis or cholangitis in the two groups did not significantly differ. However, the rate of difficult stent removal in the IS group (15.8%) was significantly higher than that in the US group (0%) (p=0.0019). US placement is preferable to IS placement for scheduled stent exchange, as it offers the same effectiveness and risk of adverse events with easier stent removal. en-copyright= kn-copyright= en-aut-name=HimeiHitomi en-aut-sei=Himei en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatoHironari en-aut-sei=Kato en-aut-mei=Hironari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SaragaiYosuke en-aut-sei=Saragai en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiiYuki en-aut-sei=Fujii en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamazakiTatsuhiro en-aut-sei=Yamazaki en-aut-mei=Tatsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UchidaDaisuke en-aut-sei=Uchida en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HoriguchiShigeru en-aut-sei=Horiguchi en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TsutsumiKoichiro en-aut-sei=Tsutsumi en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=benign biliary stricture kn-keyword=benign biliary stricture en-keyword=inside stent kn-keyword=inside stent en-keyword=plastic stent kn-keyword=plastic stent END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=3 article-no= start-page=273 end-page=280 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Usefulness of Simple Diffusion Kurtosis Imaging for Head and Neck Tumors: An Early Clinical Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Diffusion kurtosis (DK) imaging (DKI), a type of restricted diffusion-weighted imaging, has been reported to be useful for tumor diagnoses in clinical studies. We developed a software program to simultaneously create DK images with apparent diffusion coefficient (ADC) maps and conducted an initial clinical study. Multi-shot echo-planar diffusion-weighted images were obtained at b-values of 0, 400, and 800 sec/mm2 for simple DKI, and DK images were created simultaneously with the ADC map. The usefulness of the DK image and ADC map was evaluated using a pixel analysis of all pixels and a median analysis of the pixels of each case. Tumor and normal tissues differed significantly in both pixel and median analyses. In the pixel analysis, the area under the curve was 0.64 for the mean kurtosis (MK) value and 0.77 for the ADC value. In the median analysis, the MK value was 0.74, and the ADC value was 0.75. The MK and ADC values correlated moderately in the pixel analysis and strongly in the median analysis. Our simple DKI system created DK images simultaneously with ADC maps, and the obtained MK and ADC values were useful for differentiating head and neck tumors from normal tissue. en-copyright=

renal replacement therapy (CRRT) is widely used to control fluid balance, but the optimal fluid balance to improve the prognosis of patients remains debated. Appropriate fluid management may depend on hemodynamic status. We investigated the association between 90-day mortality and fluid balance/mean arterial pressure (MAP) in patients receiving CRRT. This single-center retrospective study was conducted between May 2018 and March 2021. Based on the cumulative fluid balance at 72 h after initiation of CRRT, the cases were divided into negative (< 0 mL) and positive (> 0 mL) fluid balance groups. Ninety-day mortality was higher in the positive fluid balance group (p=0.009). At 4 h before and after CRRT initiation, the mean MAP was lower in the positive fluid balance group (p<0.05). After multivariate cox adjustment, 72-h positive fluid balance was independently associated with 90-day mortality (p=0.004). In addition, the cumulative fluid balance was associated with 90-day mortality (p<0.05) in cases without shock, high APACHE II score, sepsis, dialysis dependence, or vasopressor use. A 72-h positive fluid balance was associated with 90-day mortality in patients receiving CRRT. en-copyright= kn-copyright= en-aut-name=GuoYusheng en-aut-sei=Guo en-aut-mei=Yusheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KosakaJunko en-aut-sei=Kosaka en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=fluid management kn-keyword=fluid management en-keyword=continuous renal replacement therapy kn-keyword=continuous renal replacement therapy en-keyword=mortality kn-keyword=mortality en-keyword=mean arterial pressure kn-keyword=mean arterial pressure en-keyword=daily cumulative fluid balance kn-keyword=daily cumulative fluid balance END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=3 article-no= start-page=235 end-page=241 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Endocrinological Changes after Anamorelin Administration in Patients with Gastrointestinal Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Changes in hormone levels in patients with cancer cachexia after anamorelin administration have not been fully investigated. This study aimed to determine how anamorelin affects the endocrine system in patients with gastrointestinal cancer and cachexia. We prospectively enrolled 13 patients and comprehensively investigated their body weight and levels of serum albumin, hemoglobin A1c (HbA1c), and hormones before (week 0) and 3 and 12 weeks after anamorelin administration. The variables were evaluated at week 3 in 9 patients and at week 12 in 5 patients. At week 3, anamorelin administration resulted in body weight gain and increased the levels of growth hormone and HbA1c, as well as insulin-like growth factor-1 standard deviation scores (IGF-1 SD scores). At the same time, negative correlations were observed between ƒ¢IGF-1 SD score and ƒ¢thyroidstimulating hormone (TSH) and between ƒ¢IGF-1 SD score and ƒ¢free testosterone. ƒ¢Body weight and ƒ¢IGF-1 SD score correlated positively at week 12. These results suggest that TSH and free testosterone levels can be affected 3 weeks after anamorelin administration; however, those variables tend to return to a state of equilibrium, and anabolic effects of anamorelin appear in long-term (? 12 weeks) users. en-copyright= kn-copyright= en-aut-name=KuraokaSakiko en-aut-sei=Kuraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatomiTakuya en-aut-sei=Satomi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamazakiTatsuhiro en-aut-sei=Yamazaki en-aut-mei=Tatsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HamadaKenta en-aut-sei=Hamada en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KonoYoshiyasu en-aut-sei=Kono en-aut-mei=Yoshiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KanzakiHiromitsu en-aut-sei=Kanzaki en-aut-mei=Hiromitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KatoHironari en-aut-sei=Kato en-aut-mei=Hironari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=anamorelin kn-keyword=anamorelin en-keyword=body weight kn-keyword=body weight en-keyword=cancer cachexia kn-keyword=cancer cachexia en-keyword=endocrine system kn-keyword=endocrine system END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=RNA•ÒW‚ÍAŒ‹’°’¼’°Šà‚É‚¨‚¢‚ăIƒLƒTƒŠƒvƒ‰ƒ`ƒ“E•úŽËü—Ö@“¯Žž“Š—^’†‚ɃlƒIƒAƒ“ƒ`ƒQƒ“‚̶¬‘‹­‚ð‘£i‚·‚é kn-title=RNA editing facilitates the enhanced production of neoantigens during the simultaneous administration of oxaliplatin and radiotherapy in colorectal cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KOMATSUYasuhiro en-aut-sei=KOMATSU en-aut-mei=Yasuhiro kn-aut-name=¬¼‘×_ kn-aut-sei=¬¼ kn-aut-mei=‘×_ aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=‰ªŽR‘åŠw‘åŠw‰@ˆãŽ•–òŠw‘‡Œ¤‹†‰È END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page=19 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An investigation of the internal morphology of asbestos ferruginous bodies: constraining their role in the onset of malignant mesothelioma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background@Asbestos is a fibrous mineral that was widely used in the past. However, asbestos inhalation is associated with an aggressive type of cancer known as malignant mesothelioma (MM). After inhalation, an iron-rich coat forms around the asbestos fibres, together the coat and fibre are termed an "asbestos ferruginous body" (AFB). AFBs are the main features associated with asbestos-induced MM. Whilst several studies have investigated the external morphology of AFBs, none have characterised the internal morphology. Here, cross-sections of multiple AFBs from two smokers and two non-smokers are compared to investigate the effects of smoking on the onset and growth of AFBs. Morphological and chemical observations of AFBs were undertaken by transmission electron microscopy, energy dispersive x-ray spectroscopy and selected area diffraction.
Results@The AFBs of all patients were composed of concentric layers of 2-line or 6-line ferrihydrite, with small spherical features being observed on the outside of the AFBs and within the cross-sections. The spherical components are of a similar size to Fe-rich inclusions found within macrophages from mice injected with asbestos fibres in a previous study. As such, the spherical components composing the AFBs may result from the deposition of Fe-rich inclusions during frustrated phagocytosis. The AFBs were also variable in terms of their Fe, P and Ca abundances, with some layers recording higher Fe concentrations (dense layers), whilst others lower Fe concentrations (porous layers). Furthermore, smokers were found to have smaller and overall denser AFBs than non-smokers.
Conclusions@The AFBs of smokers and non-smokers show differences in their morphology, indicating they grew in lung environments that experienced disparate conditions. Both the asbestos fibres of smokers and non-smokers were likely subjected to frustrated phagocytosis and accreted mucopolysaccharides, resulting in Fe accumulation and AFB formation. However, smokers' AFBs experienced a more uniform Fe-supply within the lung environment compared to non-smokers, likely due to Fe complexation from cigarette smoke, yielding denser, smaller and more Fe-rich AFBs. Moreover, the lack of any non-ferrihydrite Fe phases in the AFBs may indicate that the ferritin shell was intact, and that ROS may not be the main driver for the onset of MM. en-copyright= kn-copyright= en-aut-name=AvramescuMaya-Liliana en-aut-sei=Avramescu en-aut-mei=Maya-Liliana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PotiszilChristian en-aut-sei=Potiszil en-aut-mei=Christian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KunihiroTak en-aut-sei=Kunihiro en-aut-mei=Tak kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkabeKazunori en-aut-sei=Okabe en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakamuraEizo en-aut-sei=Nakamura en-aut-mei=Eizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=4 en-affil=Bell Land General Hospital kn-affil= affil-num=5 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= en-keyword=Asbestos fibre kn-keyword=Asbestos fibre en-keyword=Asbestos body kn-keyword=Asbestos body en-keyword=Malignant mesothelioma kn-keyword=Malignant mesothelioma en-keyword=Asbestos body internal morphology kn-keyword=Asbestos body internal morphology END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=6 article-no= start-page=e027046 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230321 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Heat Exposure Following the Rainy Season Is Associated With an Increased Risk of Cardiovascular Emergency Among the Elderly in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Despite the impact of heat exposure caused by global warming, few studies have investigated the hourly effects of heat exposure and the risk of cardiovascular disease (CVD) in the elderly. We examined the associations between short-term heat exposure and the risk of CVD in the elderly in Japan and evaluated possible effect-measure modifications by rainy seasons that occur in East Asia.
Methods and Results: We conducted a time-stratified case-crossover study. The study included 6527 residents in Okayama City, Japan, aged >= 65 years who were transported to emergency hospitals between 2012 and 2019 for the onset of CVD during and a few months after the rainy seasons. We examined the linear associations between temperature and CVD-related emergency calls for each year and for hourly preceding intervals before the emergency call during the most relevant months. Heat exposure during 1 month after the end of the rainy season was associated with CVD risk; the odds ratio (OR) for a 1 degrees C increase in temperature was 1.34 (95% CI, 1.29-1.40). When we further explored the nonlinear association by using the natural cubic spline model, we found a J-shaped relationship. Exposures 0 to 6 hours before the case event (preceding intervals 0-6 hours) were associated with CVD risk, particularly for the preceding interval 0 to 1 hour (OR, 1.33 [95% CI, 1.28-1.39]). For longer periods, the highest risk was at preceding intervals 0 to 23 hours (OR, 1.40 [95% CI, 1.34-1.46]).
Conclusions: Elderly individuals may be more susceptible to CVD after heat exposure during the month after the rainy season. As shown by finer temporal resolution analyses, short-term exposure to increasing temperature can trigger CVD onset. en-copyright= kn-copyright= en-aut-name=FujimotoRyohei en-aut-sei=Fujimoto en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiEtsuji en-aut-sei=Suzuki en-aut-mei=Etsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KashimaSaori en-aut-sei=Kashima en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Environmental Health Sciences Laboratory, Graduate School of Advanced Science and Engineering, Hiroshima University kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=cardiovascular disease kn-keyword=cardiovascular disease en-keyword=climate change kn-keyword=climate change en-keyword=end of the rainy season kn-keyword=end of the rainy season en-keyword=heat exposure kn-keyword=heat exposure END start-ver=1.4 cd-journal=joma no-vol=107 cd-vols= no-issue=4 article-no= start-page=043114 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230413 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Measurement of Doppler effects in a cryogenic buffer-gas cell en-subtitle= kn-subtitle= en-abstract= kn-abstract=Buffer-gas cooling is a universal cooling technique for molecules and used for various purposes. One of its ap- plications is using molecules inside a buffer-gas cell for low-temperature spectroscopy. Although a high-intensity signal is expected in the cell, complex molecular dynamics is a drawback for precise spectroscopy. In this study, we performed high-resolution absorption spectroscopy of low -J transitions in the òƒ®(0, 0, 0)-?X²ƒ°+(0, 0, 0) band of calcium monohydroxide (CaOH). CaOH molecules were produced by laser ablation in a copper cell and cooled to ?5 K using helium buffer gas. We probed the Doppler effects in a buffer-gas cell by injecting counterpropagating lasers inside the cell. The time evolutions of the Doppler width and shift were simulated using a dedicated Monte Carlo simulation and compared with data. en-copyright= kn-copyright= en-aut-name=HiramotoAyami en-aut-sei=Hiramoto en-aut-mei=Ayami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BabaMasaaki en-aut-sei=Baba en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EnomotoKatsunari en-aut-sei=Enomoto en-aut-mei=Katsunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IwakuniKana en-aut-sei=Iwakuni en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KumaSusumu en-aut-sei=Kuma en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakahashiYuiki en-aut-sei=Takahashi en-aut-mei=Yuiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TobaruReo en-aut-sei=Tobaru en-aut-mei=Reo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyamotoYuki en-aut-sei=Miyamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Graduate School of Science, Kyoto University kn-affil= affil-num=3 en-affil=Department of Physics, University of Toyama kn-affil= affil-num=4 en-affil=Institute for Laser Science, University of Electro-Communications kn-affil= affil-num=5 en-affil=Atomic, Molecular and Optical Physics Laboratory, RIKEN kn-affil= affil-num=6 en-affil=Division of Physics, Mathematics, and Astronomy, California Institute of Technology kn-affil= affil-num=7 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=2023324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Improvements in thermal efficiency and exhaust emissions with ozone addition in a natural gas-diesel dual fuel engine en-subtitle= kn-subtitle= en-abstract= kn-abstract=Here, ozone (O-3) was introduced into the intake air in a natural gas fueled engine ignited by diesel fuel, a natural gas-diesel dual fuel engine, to utilize the reactive O-radicals decomposed from the O-3 for the promotion of the ignition and for improvements in the thermal efficiency and exhaust emissions. The engine experiments were performed over a range of equivalence ratios of the natural gas in a single cylinder engine. The timing of the pilot injection of the diesel fuel was varied from early in the compression stroke to near top dead center to examine the changes in the effects of the O-3 addition on the ignition and combustion with the pilot injection timing while varying the O-3 concentration. The results showed that the combination of the O-3 addition and the early pilot injection is a means to improve the thermal efficiency and unburned emissions with a small amount of O-3. Further, the improvement in the thermal efficiency and the reduction of the unburned hydrocarbons with the O-3 addition are more pronounced for lower equivalence ratios of natural gas, while the O-3 addition has a limited effect on the thermal efficiency and the unburned hydrocarbons for higher equivalence ratios of the natural gas. en-copyright= kn-copyright= en-aut-name=KobashiYoshimitsu en-aut-sei=Kobashi en-aut-mei=Yoshimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=InagakiRyuya en-aut-sei=Inagaki en-aut-mei=Ryuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShibataGen en-aut-sei=Shibata en-aut-mei=Gen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OgawaHideyuki en-aut-sei=Ogawa en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Faculty of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Energy and Environmental Systems, Graduate School of Engineering, Hokkaido University kn-affil= affil-num=3 en-affil=Division of Energy and Environmental Systems, Graduate School of Engineering, Hokkaido University kn-affil= affil-num=4 en-affil=Division of Energy and Environmental Systems, Graduate School of Engineering, Hokkaido University kn-affil= en-keyword=Dual fuel engine kn-keyword=Dual fuel engine en-keyword=ozone kn-keyword=ozone en-keyword=natural gas kn-keyword=natural gas en-keyword=diesel fuel kn-keyword=diesel fuel en-keyword=pilot injection kn-keyword=pilot injection en-keyword=thermal efficiency kn-keyword=thermal efficiency en-keyword=exhaust emissions kn-keyword=exhaust emissions END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=2 article-no= start-page=121 end-page=129 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202304 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Complications of Percutaneous Cryoablation for Renal Tumors and Methods for Avoiding Them en-subtitle= kn-subtitle= en-abstract= kn-abstract=Percutaneous cryoablation of renal tumors is widely used because of its high efficacy and safety. This high safety can be attributed, at least in part, to the visibility of the ablated area as an gice ballh. This therapy has fewer complications (incidence, 0-7.2%) and is less invasive than surgery. Minor bleeding is inevitable in most kidney-related procedures, and indeed the most common complication of this therapy is bleeding (hematoma and hematuria). However, patients require treatment such as transfusion or transarterial embolization in only 0-4% of bleeding cases. Various other complications such as ureteral or collecting system injury, bowel injury, nerve injury, skin injury, infection, pneumothorax, and tract seeding also occur, but they are usually minor and asymptomatic. However, operators should know and avoid the various complications associated with this therapy. This study aimed to summarize the complications of percutaneous cryoablation for renal tumors and provide some techniques for achieving safe procedures. en-copyright= kn-copyright= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TomitaKoji en-aut-sei=Tomita en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UkaMayu en-aut-sei=Uka en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UmakoshiNoriyuki en-aut-sei=Umakoshi en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KawabataTakahiro en-aut-sei=Kawabata en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MunetomoKazuaki en-aut-sei=Munetomo en-aut-mei=Kazuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NagataShoma en-aut-sei=Nagata en-aut-mei=Shoma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ArakiMotoo en-aut-sei=Araki en-aut-mei=Motoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Radiology, Okayama University Hospital kn-affil= en-keyword=cryosurgery kn-keyword=cryosurgery en-keyword=kidney neoplasms kn-keyword=kidney neoplasms en-keyword=carcinoma kn-keyword=carcinoma en-keyword=renal cell kn-keyword=renal cell en-keyword=complication kn-keyword=complication END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230327 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prevalence of transthyretin amyloidosis among heart failure patients with preserved ejection fraction in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims Heart failure with preserved ejection fraction (HFpEF), which is caused by wide various conditions, has become a major public health problem. Transthyretin amyloid cardiomyopathy (ATTR-CM), which is thought to be an underdiagnosed disease, can cause HFpEF. Non-invasive diagnosis using 99mTechnetium (Tc)-pyrophosphate (PYP) scintigraphy enables accurate diagnosis of ATTR-CM. The aim of this study was to clarify the prevalence and characteristics of ATTR-CM among Japanese patients with HFpEF.
Methods and results This study was a multicentre, prospective, observational study conducted in Japan. We enrolled 373 patients with HFpEF [left ventricular (LV) ejection fraction ?50%] aged ?65 years who were admitted to the department of cardiology from September 2018 to January 2022. A 99mTc-PYP scintigraphy scan was performed during admission in all eligible patients. Cardiac 99mTc-PYP retention was graded according to a previously reported visual scale ranging from 0 to 3 points. The scan was considered positive when it revealed moderate-to-severe 99mTc-PYP uptake (Grade 2?3) in both ventricles. Patients were divided into ATTR-CM and non-ATTR-CM patients according to positive (Grade 2?3) or negative (Grade 0?1) 99mTc-PYP scintigraphy, respectively. Medical history, blood tests, electrocardiogram, echocardiography, and magnetic resonance imaging in the two groups of patients were compared. Among the 373 patients with HFpEF, 53 patients (14.2%; 95% confidence interval: 10.7?17.7) showed positive uptake on 99mTc-PYP scintigraphy. An endomyocardial biopsy was performed in 32 patients and confirmed amyloidosis in all cases. There were no significant differences between the two groups in age, severity of heart failure as assessed by the New York Heart Association (NYHA) functional classification, renal function values, left ventricular ejection fraction, and tricuspid regurgitant pressure gradient (ATTR-CM, n = 53 vs. non-ATTR-CM, n = 320). Patients in the ATTR-CM group had a higher N-terminal pro-brain natriuretic peptide level [2314 (1081?3398) vs. 900 (415?1828), P < 0.001], higher sensitive troponin T level (0.074 } 0.049 vs. 0.035 } 0.038, P < 0.001), and higher mean LV maximal wall thickness [12.5 (11?14) vs. 10.5 (9.5?11.5), P < 0.001].
Conclusions ATTR-CM is an underdiagnosed disease with a significant prevalence in Japanese patients with HFpEF. This study showed that results of examinations for ATTR-CM patients appear to be worse than those for non-ATTR-CM patients, but clinical severities of heart failure as assessed by the NYHA functional classification are similar in ATTR-CM and non-ATTR-CM patients, and the clinical overlap between ATTR-CM and non-ATTR-CM is high. en-copyright= kn-copyright= en-aut-name=NaitoTakanori en-aut-sei=Naito

Attendance efficiency (Ae) is an index that quantifies the situation that gthe re-view rate of the lecture video is 3, but the video playback time is not 3 timesh (Yamakawa and Takahata, 2022). In this article, we newly defined an index of Lecture efficiency (Le), that is, t he legal lec ture time di vided by the lecture vi deo time, i.e . Ae: lecture video time * re-viewing rate / viewi ng time per person, Le: legal le cture time / lecture vid eo time. Using this Ae and Le, about 100 online lectures conducted by the authors over the three years from 2020 to 2022 were modeled with a linear model and a nonlinear model. A regression equation of Ae=4.020-1.113*Le and Ae=4.564*exp(-0.4431*Le) were obtained. Examining these models, it was estimated that the optimal length of online lecture videos is 1/2 to 2/3 of the legal lecture time. Also, Ae at this time converged in the range of 2.0 < Ae < 2.5. Considering these together with the average number of views of the lecture videos, it was found that the students of the online lectures are considered to watch the online lecture videos with a sufficiency rate of about 0. 96 by viewin g multiple t imes. kn-abstract=@ƒŠƒAƒ‹ƒ^ƒCƒ€Œ`Ž®‚ŃIƒ“ƒ‰ƒCƒ“u‹`‚ðs‚¢C‚»‚Ìu‹`“®‰æ‚ðƒA[ƒJƒCƒu’ñ‹Ÿ‚·‚éê‡CŽóu¶‚Í•¡”‰ñ‚ÌŽóu‚ª‰Â”\‚É‚È‚é‚Ì‚Æ“¯Žž‚É•K—v‚È•”•ª‚¾‚¯‚ð‘I‘ð‚µ‚ÄŽóu‚·‚邱‚Æ‚ª‰Â”\‚É‚È‚éB‚±‚Ì󋵂ð”’l‰»‚µ‚½‚à‚Ì‚ªŽóuŒø—¦Ae ‚Å‚ ‚é(ŽRìE‚Šø, 2022)B¡‰ñCV‚½‚Éu‹`Œø—¦(Lecture efficiency, Le)‚ð’è‹`‚µCƒf[ƒ^ƒTƒCƒGƒ“ƒX‚ÌŽè–@‚ÉŠî‚«C•MŽÒ‚ª2020 ”N“x‚©‚ç2022 ”N“x‚Ì3 ”NŠÔ‚ÉŽÀŽ{‚µ‚½–ñ100 ‰ñ‚̃Iƒ“ƒ‰ƒCƒ“u‹`‚ÌAe ‚ðLe‚ðŽg‚Á‚½üŒ`ƒ‚ƒfƒ‹‚¨‚æ‚Ñ”ñüŒ`ƒ‚ƒfƒ‹‚Ń‚ƒfƒŠƒ“ƒO‚µ‚ÄŒŸ“¢‚µ‚½‚Æ‚±‚ëCÅ“K‚ȃIƒ“ƒ‰ƒCƒ“u‹`“®‰æ‚Ì’·‚³‚Í–@’èu‹`ŽžŠÔ‚ɑ΂µ‚Ä1/2 ‚©‚ç2/3 ‚Å‚ ‚邱‚Æ‚ª„’肳‚ꂽB‚Ü‚½‚±‚ÌÛ‚ÌAe ‚Í2.0 < Ae < 2.5 ‚͈̔͂Ɏû‘©‚µ‚½B‚±‚ê‚ç‚ðu‹`“®‰æ‚Ì•½‹ÏŽ‹’®‰ñ”‚Æ•¹‚¹‚ÄlŽ@‚·‚é‚ƃIƒ“ƒ‰ƒCƒ“u‹`‚ÌŽóuŽÒ‚Í•¡”‰ñ‚ÌŽ‹’®‚É‚æ‚è–ñ96 %‚Ì[‘«—¦‚ŃIƒ“ƒ‰ƒCƒ“u‹`“®‰æ‚ðŽ‹’®‚µ‚Ä‚¢‚é‚Æl‚¦‚ç‚ê‚邱‚Æ‚ª‚í‚©‚Á‚½B en-copyright= kn-copyright= en-aut-name=YamakawaJunji en-aut-sei=Yamakawa en-aut-mei=Junji kn-aut-name=ŽR샎Ÿ kn-aut-sei=ŽRì kn-aut-mei=ƒŽŸ aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=‰ªŽR‘åŠwŠwpŒ¤‹†‰@Ž©‘R‰ÈŠwŠwˆæ en-keyword=ƒIƒ“ƒ‰ƒCƒ“u‹`iOnline lecturej kn-keyword=ƒIƒ“ƒ‰ƒCƒ“u‹`iOnline lecturej en-keyword=ŽóuŒø—¦iAttendance efficiencyj kn-keyword=ŽóuŒø—¦iAttendance efficiencyj en-keyword=u‹`Œø—¦iLecture efficiencyj kn-keyword=u‹`Œø—¦iLecture efficiencyj END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=5 article-no= start-page=1971 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230302 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Role of the Pfannenstiel Incision in Robotic Hepato-Pancreato-Biliary Surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract=Studies remain limited on the role of the Pfannenstiel incision in minimally invasive hepato-pancreato-biliary (HPB) surgery, especially robotic surgery. The role of various extraction sites in robotic HPB surgery should be understood. Herein, we describe the surgical techniques, outcomes, advantages, and disadvantages of the Pfannenstiel incision in robotic pancreatic surgery. Seventy patients underwent robotic pancreatectomy at our institution between September 2020 and October 2022. The Pfannenstiel incision was used for specimen retrieval in 55 patients. Advantages of the Pfannenstiel incision include less pain, cosmetic benefits, and a lower incidence of complications. Moreover, the specimen could be removed using the robotic system docked. However, all complex reconstructions should be performed intra-abdominally during robotic pancreatoduodenectomies. The incidence of mortality and postoperative pancreatic fistula (grade B) was 0% and 9.1%, respectively. During the median follow-up (11.2 months) after surgery, complications at the Pfannenstiel incision site included surgical site infection (n = 1, 1.8%) and incisional hernia (n = 1, 1.8%). The Pfannenstiel incision can be a useful option for specimen retrieval in minimally invasive HPB surgery, according to the surgeon's preferences and the patient's condition. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UmedaYuzo en-aut-sei=Umeda en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshidaRyuichi en-aut-sei=Yoshida en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KimuraJiro en-aut-sei=Kimura en-aut-mei=Jiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HataNanako en-aut-sei=Hata en-aut-mei=Nanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YagiTakahito en-aut-sei=Yagi en-aut-mei=Takahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=robotic surgery kn-keyword=robotic surgery en-keyword=minimally invasive surgery kn-keyword=minimally invasive surgery en-keyword=hepato-pancreato-biliary surgery kn-keyword=hepato-pancreato-biliary surgery en-keyword=Pfannenstiel incision kn-keyword=Pfannenstiel incision END start-ver=1.4 cd-journal=joma no-vol=34 cd-vols= no-issue=02 article-no= start-page=2350006 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Geometrical proof of generalized mirror transformation of projective hypersurfaces en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this paper, we propose a geometrical proof of the generalized mirror transformation of genus 0 Gromov?Witten invariants of degree k hypersurface in CPN-1 en-copyright= kn-copyright= en-aut-name=JinzenjiMasao en-aut-sei=Jinzenji en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Mathematics, Okayama University kn-affil= en-keyword=Mirror symmetry kn-keyword=Mirror symmetry en-keyword=moduli space of quasimaps kn-keyword=moduli space of quasimaps en-keyword=excess intersection kn-keyword=excess intersection en-keyword=generalized mirror transformation kn-keyword=generalized mirror transformation END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=3 article-no= start-page=1921 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202302 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Microcalcification and Tc-99m-Pyrophosphate Uptake without Increased Bone Metabolism in Cardiac Tissue from Patients with Transthyretin Cardiac Amyloidosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Transthyretin cardiac amyloidosis (ATTR-CA) is characterized by high Tc-99m-labeled bone tracer uptake in the heart. However, the mechanism of bone tracer uptake into the heart remains controversial. Since bone tracer uptake into metastatic bone tumors is thought to be associated with increased bone metabolism, we examined Tc-99m-pyrophosphate (PYP) scintigraphy findings, endomyocardial biopsy (EMB) tissue findings, and the expression of bone metabolism-related genes in the EMB tissues in patients with ATTR-CA, amyloid light-chain cardiac amyloidosis (AL-CA), and noncardiac amyloidosis (non-CA) in this study. The uptake of Tc-99m-PYP in the heart was significantly higher in the ATTR-CA patients than in the AL-CA and non-CA patients. A higher percentage of ATTR-CA EMB tissue showed von Kossa-positive microparticles: ATTR-CA, 62%; AL-CA, 33%; and non-CA, 0%. Calcified microparticles were identified using transmission electron microscopy. However, none of the osteogenic marker genes, osteoclastic marker genes, or phosphate/pyrophosphate-related genes were upregulated in the EMB samples from ATTR-CA patients compared to those from AL-CA and non-CA patients. These results suggest that active calcification-promoting mechanisms are not involved in the microcalcification observed in the heart in ATTR-CA. The mechanisms explaining bone tracer uptake in the heart, which is stronger than that in the ribs, require further investigation. en-copyright= kn-copyright= en-aut-name=MoriAtsushi en-aut-sei=Mori en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoYukihiro en-aut-sei=Saito en-aut-mei=Yukihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IidaToshihiro en-aut-sei=Iida en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AkagiSatoshi en-aut-sei=Akagi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshidaMasashi en-aut-sei=Yoshida en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TaniyamaMakiko en-aut-sei=Taniyama en-aut-mei=Makiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Chronic Kidney Disease and Cardiovascular Disease, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of General Medicine, Tamano Division, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=ATTR kn-keyword=ATTR en-keyword=Tc-99m-labeled bone scintigraphy kn-keyword=Tc-99m-labeled bone scintigraphy en-keyword=calcified microparticle kn-keyword=calcified microparticle END start-ver=1.4 cd-journal=joma no-vol=62 cd-vols= no-issue=4 article-no= start-page=195 end-page=201 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=2022 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Immunohistochemistry for IRTA1 and MNDA helps differentiate gastric MALT lymphoma from chronic gastritis/reactive lymphocyte hyperplasia en-subtitle= kn-subtitle= en-abstract= kn-abstract=It is difficult to histologically differentiate extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) from chronic gastritis (CG)/ reactive lymphoid hyperplasia (RLH). To determine whether immunohistochemistry for IRTA1 and MNDA can differentiate gastric MALT lymphoma from CG/RLH, we investigated 81 stomach biopsy specimens [Wotherspoon grade (WG) 1, 11 cases; WG 2, 9 cases; WG 3, 20 cases; WG 4, 31 cases; and WG 5, 10 cases]. According to a previously reported algorithm involving PCR for immunoglobulin heavy (IgH) chain locus rearrangement, all 81 cases were divided into three groups: CG/RLH (55 cases), MALT lymphoma (19 cases) groups, and IgH undetectable group (7 cases). We analyzed the CG/RLH and MALT lymphoma groups. The median percentage of IRTA1-positive cells was 0% (range 0%-90.6%) in the CG/RLH group and 43.5% (range 0%-97.6%) in the MALT lymphoma group (p < 0.0001). The median percentage of MNDA-positive cells was 32.4% (range 0%-97.6%) in the CG/RLH group and 55.1% (range 0%-97.6%) in the MALT lymphoma group (p = 0.0044). These results indicate that immunohistochemistry for IRTA1 and MNDA can help dif-ferentiate gastric MALT lymphoma from CG/RLH. en-copyright= kn-copyright= en-aut-name=AyadaYoshiyuki en-aut-sei=Ayada en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IgawaTakuro en-aut-sei=Igawa en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NaoiYusuke en-aut-sei=Naoi en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HorikawaKyosuke en-aut-sei=Horikawa en-aut-mei=Kyosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TabataTetsuya en-aut-sei=Tabata en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshinoTadashi en-aut-sei=Yoshino en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pathology, National Hospital Organization Okayama Medical Center kn-affil= affil-num=6 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=MALT lymphoma kn-keyword=MALT lymphoma en-keyword=chronic gastritis kn-keyword=chronic gastritis en-keyword=reactive lymphoid hyperplasia kn-keyword=reactive lymphoid hyperplasia en-keyword=IRTA1 kn-keyword=IRTA1 en-keyword=MNDA kn-keyword=MNDA END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=2 article-no= start-page=1579 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230115 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Differences in Stress Perception of Medical Students Depending on In-Person Communication and Online Communication during the COVID-19 Pandemic: A Japanese Cross-Sectional Survey en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Excessive psychological stress in medical students affects their mental health and causes problems such as burnout and depression. Furthermore, changes in the learning environment to online learning due to the COVID-19 pandemic have had a psychological effect on medical students. However, the relationships between medical students' perceived stress and different methods of communication, including in-person and online communication, remain unclear. The purpose of this study was to investigate the differences in stress perception of medical students depending on in-person communication and online communication during the COVID-19 pandemic. Methods: This study was a cross-sectional study conducted from September to October in 2020. All of the students of Okayama University School of Medicine were asked to participate in a questionnaire survey. The explanatory variables were the frequency and length of communications with others (by in-person or online communication), empathy, and lifestyle. The main outcome measure was perceived stress. Subgroup analysis was conducted for students who preferred to be by themselves and students who preferred to study together and interact with other people. Univariate analysis and multivariate multiple regression analysis were conducted. Gender and grade, which have been shown to be associated with stress in previous studies, were used as covariates for multiple regression analysis. Results: Valid responses to the questionnaire survey were received from 211 (29.4%) of the 717 students. There was no significant association between perceived stress and online communication, but the number of people with which students had in-person communication (1-2 people compared to 0 as a control, regression coefficient [B] = -4.4, 95% confidence interval [CI]; -7.8, -1.1, more than 10 people, B = -12, 95% CI: -18, -5.8) and the length of communication (more than 120 min, B = -4.5, 95% CI: -8.1, -0.92) were associated with a reduction in perceived stress. In subgroup analysis, the number of people with in-person communication and the length of communication had significant associations with stress reduction even in the group of students who had a preference for being by themselves. Conclusion: In-person communications rather than online communications were associated with a lower level of perceived stress. In subgroup analysis, this trend was statistically significant in the group of students who had a preference for being by themselves. en-copyright= kn-copyright= en-aut-name=TokumasuKazuki en-aut-sei=Tokumasu en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakamotoYoko en-aut-sei=Sakamoto en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ObikaMikako en-aut-sei=Obika en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KataokaHitomi en-aut-sei=Kataoka en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Medicine, John A.

Several efforts have been made to decrease the incidence of DGE. However, the optimal anastomotic method for gastro/duodenojejunostomy (GJ) remains debatable. Moreover, few studies have reported the impact of GJ surgical techniques on outcomes following robotic pancreatoduodenectomy (RPD). This study aimed to investigate the surgical outcomes of robot-sewn and stapled GJ anastomoses in RPD. Methods: Forty patients who underwent RPD at the Okayama University Hospital between September 2020 and October 2022 were included. The outcomes between robot-sewn and stapled anastomoses were compared. Results: The mean [standard deviation (SD)] operative and GJ time were 428 (63.5) and 34.0 (15.0) minutes, respectively. Postoperative outcomes included an overall incidence of DGE of 15.0%, and the mean postoperative hospital stays were 11.6 (5.3) days in length. The stapled group (n = 21) had significantly shorter GJ time than the robot-sewn group (n = 19) (22.7 min versus 46.5 min, p < 0.001). Moreover, stapled GJ cases were significantly associated with a lower incidence of DGE (0% versus 21%, p = 0.01). Although not significant, the stapled group tended to have shorter postoperative hospital stays (9.9 days versus 13.5 days, p = 0.08). Conclusions: Our findings suggest that stapled GJ anastomosis might decrease anastomotic GJ time and incidence of DGE after RPD. Surgeons should select a suitable method for GJ anastomosis based on their experiences with RPD. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UmedaYuzo en-aut-sei=Umeda en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshidaRyuichi en-aut-sei=Yoshida en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KimuraJiro en-aut-sei=Kimura en-aut-mei=Jiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HataNanako en-aut-sei=Hata en-aut-mei=Nanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YagiTakahito en-aut-sei=Yagi en-aut-mei=Takahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=pancreatoduodenectomy kn-keyword=pancreatoduodenectomy en-keyword=robotic surgery kn-keyword=robotic surgery en-keyword=gastrojejunostomy kn-keyword=gastrojejunostomy en-keyword=delayed gastric emptying kn-keyword=delayed gastric emptying END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=497 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Interspecific Variability in Growth Characteristics and Phytoremediation of Cu by Free-Floating Azolla Macrophytes en-subtitle= kn-subtitle= en-abstract= kn-abstract=The phytoremediation potential of aquatic plants, particularly for Cu, is scarcely reported in the pertinent literature. In this regard, differential growth behavior and phytoaccumulation ability of three free-floating Azolla species (A. japonica, A. pinnata, and A. hybrid) were evaluated in a climatically controlled (a temperature of 25/20 degrees C, light/dark 16/8 h, a light intensity of 60 mu mol m(-2) s(-1), and a relative humidity of 65%) microcosm study. Azolla plants were exposed to solutions having three Cu concentrations (0, 3, and 6 mg L-1) under two incubation periods (4 and 8 days). Different Cu treatments significantly reduced Azolla biomass during both incubation periods and A. pinnata was the most sensitive species. Azolla plants grown in aqueous solutions showed substantial variations in Cu removal capacity. Higher bioconcentration values displayed by Azolla plants indicated that these plants can be deployed as potential plants for Cu removal from Cu contaminated water. Nevertheless, the plants exposed to higher Cu concentrations displayed color changes and root detachment due to Cu phytotoxic effects which may also ultimately lead to plant death. Significant correlations between Cu removed from the aqueous solutions and Cu contents of plant biomass indicated that Cu phytoremediation by Azolla plants was due to the phytoaccumulation mechanism because the removed Cu from aqueous solutions was accumulated in plant biomass. Introduced Azolla species, i.e., A. hybrid, displayed comparable Cu removal efficiency with naturally grown Azolla species, i.e., A. japonica and A. pinnata. Tested Azolla species proved to be suitable candidates to remediate Cu contaminated water and can be deployed for phytoremediation. en-copyright= kn-copyright= en-aut-name=AkhtarMuhammad Shahbaz en-aut-sei=Akhtar en-aut-mei=Muhammad Shahbaz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AslamSohaib en-aut-sei=Aslam en-aut-mei=Sohaib kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DittaAllah en-aut-sei=Ditta en-aut-mei=Allah kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AlbalawiBedur Faleh A. en-aut-sei=Albalawi en-aut-mei=Bedur Faleh A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkiYoko en-aut-sei=Oki en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakashimaYoshitaka en-aut-sei=Nakashima en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Environmental Sciences, Forman Christian College University kn-affil= affil-num=2 en-affil=Department of Environmental Sciences, Forman Christian College University kn-affil= affil-num=3 en-affil=Department of Environmental Sciences, Shaheed Benazir Bhutto University kn-affil= affil-num=4 en-affil=Department of Biology, University of Tabuk kn-affil= affil-num=5 en-affil=Department of Environmental Management Engineering, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Department of Environmental Management Engineering, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Azolla biomass kn-keyword=Azolla biomass en-keyword=bioconcentration factor kn-keyword=bioconcentration factor en-keyword=Cu removal efficiency kn-keyword=Cu removal efficiency en-keyword=Cu toxicity kn-keyword=Cu toxicity en-keyword=translocation factor kn-keyword=translocation factor END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=1 article-no= start-page=380 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221229 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Thickness Measurement at High Lift-Off for Underwater Corroded Iron-Steel Structures Using a Magnetic Sensor Probe en-subtitle= kn-subtitle= en-abstract= kn-abstract=Infrastructure facilities that were built approximately half a century ago have rapidly aged. Steel sheet piles, the inspection object in this study, are severely corroded, resulting in cave-in damages at wharfs. To solve such a problem, non-destructive inspection techniques are required. We previously demonstrated plate thickness measurement using extremely low-frequency eddy current testing. However, when the steel sheet piles are located in water, shellfish adhere to their surface, causing a lift-off of several tens of millimeters. Therefore, this large lift-off hinders the thickness measurement owing to fluctuations of magnetic signals. In this study, sensor probes with different coil diameters were prototyped and the optimum size for measuring steel sheet piles at high lift-off was investigated. Using the probes, the magnetic field was applied with a lift-off range from 0 to 80 mm, and the intensity and phase of the detected magnetic field were analyzed. Subsequently, by increasing the probe diameter, a good sensitivity was obtained for the thickness estimation with a lift-off of up to 60 mm. Moreover, these probes were used to measure the thickness of actual steel sheet piles, and measurements were successfully obtained at a high lift-off. en-copyright= kn-copyright= en-aut-name=AdachiShoya en-aut-sei=Adachi en-aut-mei=Shoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayashiMinoru en-aut-sei=Hayashi en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawakamiTaisei en-aut-sei=Kawakami en-aut-mei=Taisei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AndoYuto en-aut-sei=Ando en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WangJin en-aut-sei=Wang en-aut-mei=Jin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakaiKenji en-aut-sei=Sakai en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KiwaToshihiko en-aut-sei=Kiwa en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IshikawaToshiyuki en-aut-sei=Ishikawa en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TsukadaKeiji en-aut-sei=Tsukada en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=8 en-affil=Department of Civil, Environmental and Applied System Engineering, Faculty of Environmental and Urban Engineering, Kansai University kn-affil= affil-num=9 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=eddy current testing kn-keyword=eddy current testing en-keyword=high lift-off thickness measurement kn-keyword=high lift-off thickness measurement en-keyword=magnetic sensor kn-keyword=magnetic sensor en-keyword=corrosion kn-keyword=corrosion en-keyword=underwater steel structure kn-keyword=underwater steel structure END start-ver=1.4 cd-journal=joma no-vol=2022 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221211 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Surgical site infections in thyroid and parathyroid surgery in Japan: An analysis of the Japan Nosocomial Infections Surveillance database from 2013 to 2020 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Surgical site infections (SSIs) after thyroid surgery are rare complications, with incidence rates of 0.3%-1.6%. Using a Japanese database, we conducted exploratory analyses on the incidence of SSIs, investigated the incidence of SSIs by the National Nosocomial Infections Surveillance risk index, and identified the causative bacteria of SSIs. SSIs occurred in 50 (0.7%) of 7388 thyroid surgery cases. Risk index-0 patients had the lowest incidence rate of SSIs (0.41%). The incidence of SSIs in risk index-1 patients was 3.05 times the incidence of SSIs in risk index-0 patients. The rate of SSI occurrence for risk index-2 patients was 4.22 times the rate of SSI occurrence for risk index-0 patients. Thirty-one bacterial species were identified as the cause of SSIs in thyroid surgery cases, of which 12 (38.7%) SSIs were caused by Staphylococcus aureus and Staphylococcus epidermidis. Of the nine SSIs caused by Staphylococcus aureus, 55.6% (five cases) were attributed to methicillin-resistant Staphylococcus aureus. Therefore, routine prophylactic antibiotic administration should be avoided, while the target for administration should be narrowed, according to the SSI risk. Administration of prophylactic antibiotics, such as 2 g piperacillin or 1 g cefazolin, is considered appropriate. en-copyright= kn-copyright= en-aut-name=IwataniTsuguo en-aut-sei=Iwatani en-aut-mei=Tsuguo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoShinya en-aut-sei=Saito en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=parathyroid surgery kn-keyword=parathyroid surgery en-keyword=prophylactic antibiotic kn-keyword=prophylactic antibiotic en-keyword=risk factor kn-keyword=risk factor en-keyword=surgical site infection kn-keyword=surgical site infection en-keyword=thyroid surgery kn-keyword=thyroid surgery END start-ver=1.4 cd-journal=joma no-vol=44 cd-vols= no-issue=1 article-no= start-page=26 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221209 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Chemopreventive effects and anti-tumorigenic mechanisms of Actinidia arguta, known as sarunashi in Japan toward 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK)- induced lung tumorigenesis in a/J mouse en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Previously, we reported the inhibitory effect of Actinidia arguta juice, known as sarunashi juice (sar-j) in Japan, on mutagenesis, inflammation, and mouse skin tumorigenesis. The components of A. arguta responsible for the anti-mutagenic effects were identified to be water-soluble, heat-labile phenolic compounds. We proposed isoquercetin (isoQ) as a candidate anticarcinogenic component. In this study, we sought to investigate the chemopreventive effects of A. arguta juice and isoQ on 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK)-induced lung tumorigenesis in A/J mice, and identify the possible mechanisms underlying the anti-tumorigenic effects of A. arguta.

Results
The number of tumor nodules per mouse lung in the group injected with NNK and administered A. arguta juice orally was significantly lower than that in the group injected with NNK only. Oral administration of isoQ also reduced the number of nodules in the mouse lungs. As expected, the mutagenicity of NNK and 1-methyl-3-nitro-1-nitrosoguanidine (MNNG) detected using S. typhimurium TA1535 decreased in the presence of sar-j. However, NNK and MNNG mutagenicity detected using S. typhimurium YG7108, a strain lacking the O6-methylguanine DNA methyltransferases (ogtST and adaST) did not decrease in the presence of sar-j suggesting that sar-j may mediate its antimutagenic effect by enhancing the DNA damage repair by ogtST and adaST. Phosphorylation of Akt, with or without epidermal growth factor stimulation, in A549 cells was significantly decreased following sar-j and isoQ treatment, indicating that components in sar-j including isoQ suppressed the PI3K/AKT signaling pathways.

Conclusions
Sar-j and isoQ reduced NNK-induced lung tumorigenesis. Sar-j targets both the initiation and growth/progression steps during carcinogenesis, specifically via anti-mutagenesis, stimulation of alkyl DNA adduct repair, and suppression of Akt-mediated growth signaling. IsoQ might contribute in part to the biological effects of sar-j via suppression of Akt phosphorylation, but it may not be the main active ingredient. en-copyright= kn-copyright= en-aut-name=TakataJun en-aut-sei=Takata en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyakeNaoko en-aut-sei=Miyake en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SaikiYusuke en-aut-sei=Saiki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TadaMisako en-aut-sei=Tada en-aut-mei=Misako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SasakiKensuke en-aut-sei=Sasaki en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KuboToshio en-aut-sei=Kubo en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KiuraKatsuyuki en-aut-sei=Kiura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=Arimoto-KobayashiSakae en-aut-sei=Arimoto-Kobayashi en-aut-mei=Sakae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Akt signal transduction kn-keyword=Akt signal transduction en-keyword=Lung tumorigenesis kn-keyword=Lung tumorigenesis en-keyword=Anti-mutagenesis kn-keyword=Anti-mutagenesis en-keyword=DNA methylation kn-keyword=DNA methylation en-keyword=Tobacco-specific nitrosamine kn-keyword=Tobacco-specific nitrosamine en-keyword=Isoquercetin kn-keyword=Isoquercetin END start-ver=1.4 cd-journal=joma no-vol=471 cd-vols= no-issue= article-no= start-page=214742 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202211 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Geometric, electronic and spin structures of the CaMn4O5 catalyst for water oxidation in oxygen-evolving photosystem II. Interplay between experiments and theoretical computations en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this review is to elucidate geometric structures of the catalytic CaMn4Ox (x = 5, 6) cluster in the Kok cycle for water oxidation in the oxygen evolving complex (OEC) of photosystem II (PSII) based on the high-resolution (HR) X-ray diffraction (XRD) and serial femtosecond crystallography (SFX) experiments using the X-ray free-electron laser (XFEL). Quantum mechanics (QM) and QM/molecular mechanics (MM) computations are performed to elucidate the electronic and spin structures of the CaMn4Ox (x = 5, 6) cluster in five states S-i (i = 0 similar to 4) on the basis of the X-ray spectroscopy, electron paramagnetic resonance (EPR) and related experiments. Interplay between the experiments and theoretical computations has been effective to elucidate the coordination structures of the CaMn4Ox (x = 5, 6) cluster ligated by amino acid residues of the protein matrix of PSII, valence states of the four Mn ions and total spin states by their exchange-couplings, and proton-shifted isomers of the CaMn4Ox (x = 5, 6) cluster. The HR XRD and SFX XFEL experiments have also elucidated the biomolecular systems structure of OEC of PSII and the hydrogen bonding networks consisting of water molecules, chloride anions, etc., for water inlet and proton release pathways in PSII. Large-scale QM/MM computations have been performed for elucidation of the hydrogen bonding distances and angles by adding invisible hydrogen atoms to the HR XRD structure. Full geometry optimizations by the QM and QM/MM methods have been effective for elucidation of the molecular systems structure around the CaMn4Ox (x = 5, 6) cluster in OEC. DLPNO-CCSD(T-0) method has been applied to elucidate relative energies of possible intermediates in each state of the Kok cycle for water oxidation. Implications of these results are discussed in relation to the blueprint for developments of artificial catalysts for water oxidation. en-copyright= kn-copyright= en-aut-name=YamaguchiKizashi en-aut-sei=Yamaguchi en-aut-mei=Kizashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShojiMitsuo en-aut-sei=Shoji en-aut-mei=Mitsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IsobeHiroshi en-aut-sei=Isobe en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawakamiTakashi en-aut-sei=Kawakami en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyagawaKoichi en-aut-sei=Miyagawa en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SugaMichihiro en-aut-sei=Suga en-aut-mei=Michihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AkitaFusamichi en-aut-sei=Akita en-aut-mei=Fusamichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShenJian-Ren en-aut-sei=Shen en-aut-mei=Jian-Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Center for Quantum Information and Quantum Biology, Osaka University kn-affil= affil-num=2 en-affil=Center of Computational Sciences, Tsukuba University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, and Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=RIKEN Center for Computational Science kn-affil= affil-num=5 en-affil=Center of Computational Sciences, Tsukuba University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, and Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Research Institute for Interdisciplinary Science, and Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, and Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Water oxidation kn-keyword=Water oxidation en-keyword=Oxygen evolution kn-keyword=Oxygen evolution en-keyword=Photosystem II kn-keyword=Photosystem II en-keyword=HR XRD kn-keyword=HR XRD en-keyword=SFX XFEL kn-keyword=SFX XFEL en-keyword=QM/MM calculation kn-keyword=QM/MM calculation en-keyword=DLPNO CCSD(T-0) computations, Oxyl radical character kn-keyword=DLPNO CCSD(T-0) computations, Oxyl radical character END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=6 article-no= start-page=673 end-page=678 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Handling of Germline Findings in Clinical Comprehensive Cancer Genomic Profiling en-subtitle= kn-subtitle= en-abstract= kn-abstract=Patients found to have presumed germline pathogenic variants (PGPVs) during comprehensive genomic profiling (CGP) require genetic counseling (GC) referrals.

However, the proportion of patients who undergo GC should be improved. en-copyright= kn-copyright= en-aut-name=Okazawa-SakaiMika en-aut-sei=Okazawa-Sakai en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoYasuko en-aut-sei=Yamamoto en-aut-mei=Yasuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FutagawaMashu en-aut-sei=Futagawa en-aut-mei=Mashu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkamuraMiki en-aut-sei=Okamura en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyawakiSatoko en-aut-sei=Miyawaki en-aut-mei=Satoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishinaTomohiro en-aut-sei=Nishina en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakeharaKazuhiro en-aut-sei=Takehara en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KozukiToshiyuki en-aut-sei=Kozuki en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TomidaShuta en-aut-sei=Tomida en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HyodoIchinosuke en-aut-sei=Hyodo en-aut-mei=Ichinosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OhsumiShozo en-aut-sei=Ohsumi en-aut-mei=Shozo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HirasawaAkira en-aut-sei=Hirasawa en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Clinical Genomic Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cancer Genomic Medicine, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=3 en-affil=Department of Clinical Genomic Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Hereditary Tumors, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=5 en-affil=Department of Cancer Genomic Medicine, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=6 en-affil=Department of Cancer Genomic Medicine, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=7 en-affil=Department of Gynecologic Oncology, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=8 en-affil=Department of Clinical Research Center, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=9 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Cancer Genomic Medicine, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=11 en-affil=Department of Hereditary Tumors, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=12 en-affil=Department of Clinical Genomic Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=comprehensive genomic profiling kn-keyword=comprehensive genomic profiling en-keyword=hereditary cancer kn-keyword=hereditary cancer en-keyword=germline findings kn-keyword=germline findings en-keyword=presumed germline pathogenic variant(s) kn-keyword=presumed germline pathogenic variant(s) en-keyword=genetic counseling kn-keyword=genetic counseling END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=5 article-no= start-page=547 end-page=555 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=First-line Combination Strategy Provides Favorable 5-year Outcomes for Patients with Lupus Nephritis: A Single-center Observational Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=This observational study aimed to clarify the long-term results of the combination of mizoribine (MZB), tacrolimus (TAC) and prednisolone as first-line therapy for lupus nephritis (LN). This was our institutionfs standard therapy between 2009 and 2015, when we saw 36 patients with LN. When a patient thus treated achieved SLEDAI remission (= 0) and/or the prednisolone dose could be tapered to 5 mg/day, either MZB or TAC was stopped, and the other was continued for maintenance therapy. If treatment failure or relapse occurred, second-line therapy was introduced. At years 1 and 5, overall complete renal response and SLEDAI remission were 94% and 88%, and 50% and 62%, respectively. Excluding 2 cases lost to follow-up, medications after 5 years were as follows: 20 (59%) were stable on 1 drug (MZB or TAC), 11 (32%) required continuation of both drugs (MZB + TAC), and 3 (9%) required second-line therapy. The 5-year retention rate was 91% (non-secondline), with 0% of relapse in this group. Our first-line combination strategy showed high remission rates in the induction phase, and subsequent maintenance therapy demonstrated good outcomes for up to 5 years. Research that fine-tunes the order of therapeutic agents and institutes appropriate treatment goals may further improve long-term outcomes for patients with LN. en-copyright= kn-copyright= en-aut-name=KagawaHidetoshi en-aut-sei=Kagawa en-aut-mei=Hidetoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamanakaRyutaro en-aut-sei=Yamanaka en-aut-mei=Ryutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiromasaTsutomu en-aut-sei=Hiromasa en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Nephrology and Rheumatology, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=2 en-affil=Department of Nephrology and Rheumatology, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=3 en-affil=Department of Nephrology and Rheumatology, Japanese Red Cross Society Himeji Hospital kn-affil= en-keyword=combination therapy kn-keyword=combination therapy en-keyword=first-line therapy kn-keyword=first-line therapy en-keyword=lupus nephritis kn-keyword=lupus nephritis en-keyword=mizoribine kn-keyword=mizoribine en-keyword=tacrolimus kn-keyword=tacrolimus END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=1 article-no= start-page=224 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221029 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bile pigments in emergency and critical care medicine en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bile pigments, such as bilirubin and biliverdin, are end products of the heme degradation pathway in mammals and are widely known for their cytotoxic effects. However, recent studies have revealed that they exert cytoprotective effects through antioxidative, anti-inflammatory, and immunosuppressive properties. All these mechanisms are indispensable in the treatment of diseases in the field of emergency and critical care medicine, such as coronary ischemia, stroke, encephalomyelitis, acute lung injury/acute respiratory distress syndrome, mesenteric ischemia, and sepsis. While further research is required before the safe application of bile pigments in the clinical setting, their underlying mechanisms shed light on their utilization as therapeutic agents in the field of emergency and critical care medicine. This article aims to summarize the current understanding of bile pigments and re-evaluate their therapeutic potential in the diseases listed above. en-copyright= kn-copyright= en-aut-name=SeyaMizuki en-aut-sei=Seya en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AokageToshiyuki en-aut-sei=Aokage en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Bile pigments kn-keyword=Bile pigments en-keyword=Emergency and critical care medicine kn-keyword=Emergency and critical care medicine en-keyword=Antioxidant therapy kn-keyword=Antioxidant therapy END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=1 article-no= start-page=145 end-page=173 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202301 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Positivity and Hierarchical Structure of four Green Functions Corresponding to a Bending Problem of a Beam on a half line en-subtitle= kn-subtitle= en-abstract= kn-abstract=We consider the boundary value problem for fourth order linear ordinary differential equation in a half line (0,‡), which represents bending of a beam on an elastic foundation under a tension.

However, endoscopic findings have not been sufficiently investigated. We investigated the phenotypic expression of gastric adenoma (low-grade dysplasia) and gastric cancer (high-grade dysplasia or carcinoma) in patients with FAP and clarified their relationships to endoscopic findings. Of 29 patients with FAP who underwent esophagogastroduodenoscopy between 2005 and 2020, 11 (38%) had histologically confirmed gastric neoplasms, including 23 lesions of gastric adenoma and 9 lesions of gastric cancer. The gastric neoplasms were classified into 3 phenotypes (gastric, mixed, or intestinal type) according to the immunostaining results and evaluated for location (U or M region: upper or middle third of the stomach or L region: lower third of the stomach), color (same as the background mucosa, whitish, or reddish), macroscopic type (elevated, flat, or depressed), background mucosal atrophy (present or absent), fundic gland polyps in the surrounding mucosa (present or absent), and morphologic changes in tumor size. Elevated whitish gastric adenomas were further subdivided by macroscopic type (flat elevated, protruded, or elevated with a central depression) and color (milky- or pinkish-white). The gastric adenomas included gastric (11/23, 48%), mixed (4/23, 17%), and intestinal (8/23, 35%) phenotypes. In contrast, no lesions of gastric cancers showed a gastric phenotype (0/9, 0%), while 5 (56%) and 4 (44%) lesions were intestinal and mixed phenotypes, respectively. Gastric cancers were significantly more likely than gastric adenomas to present as reddish depressed lesions with gastric atrophy. All gastric-type adenomas occurred in non-atrophic mucosa, in mucosa with fundic gland polyps in the periphery, in the U or M region, and as flat elevated or protruded lesions with a milky-white color. Half of the lesions increased in size. Meanwhile, the typical endoscopic features of intestinal-type adenomas included occurrence in the L region and elevated pinkish-white lesions with central depression. None of the intestinal-type adenomas increased in size during the observation period. We believe that these endoscopic features will be useful for the prompt diagnosis and appropriate management of gastric neoplasms in patients with FAP. en-copyright= kn-copyright=

en-abstract= kn-abstract=Plants protect themselves from microorganisms by inducing pattern-triggered immunity (PTI) via recognizing microbe-associated molecular patterns (MAMPs), conserved across many microbes. Although the MAMP perception mechanism and initial events during PTI have been well-characterized, knowledge of the transcriptomic changes in plants, especially monocots, is limited during the intermediate and terminal stages of PTI. Here, we report a time-series high-resolution RNA-sequencing (RNA-seq) analysis during PTI in the leaf disks of Brachypodium distachyon. We identified 6,039 differentially expressed genes (DEGs) in leaves sampled at 0, 0.5, 1, 3, 6, and 12 hours after treatment (hat) with the bacterial flagellin peptide flg22. The k-means clustering method classified these DEGs into 10 clusters (6 upregulated and 4 downregulated). Based on the results, we selected 10 PTI marker genes in B. distachyon. Gene ontology (GO) analysis suggested a tradeoff between defense responses and photosynthesis during PTI. The data indicated the recovery of photosynthesis started at least at 12 hat. Over-representation analysis of transcription factor genes and cis-regulatory elements in DEG promoters implied the contribution of 12 WRKY transcription factors in plant defense at the early stage of PTI induction. en-copyright= kn-copyright= en-aut-name=OgasaharaTsubasa en-aut-sei=Ogasahara en-aut-mei=Tsubasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KouzaiYusuke en-aut-sei=Kouzai en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeMegumi en-aut-sei=Watanabe en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakahashiAkihiro en-aut-sei=Takahashi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahagiKotaro en-aut-sei=Takahagi en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KimJune-Sik en-aut-sei=Kim en-aut-mei=June-Sik kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuiHidenori en-aut-sei=Matsui en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamamotoMikihiro en-aut-sei=Yamamoto en-aut-mei=Mikihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ToyodaKazuhiro en-aut-sei=Toyoda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IchinoseYuki en-aut-sei=Ichinose en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MochidaKeiichi en-aut-sei=Mochida en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NoutoshiYoshiteru en-aut-sei=Noutoshi en-aut-mei=Yoshiteru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Kihara Institute for Biological Research, Yokohama City University kn-affil= affil-num=6 en-affil=Bioproductivity Informatics Research Team, RIKEN Center for Sustainable Resource Science kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=9 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=10 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=11 en-affil=Bioproductivity Informatics Research Team, RIKEN Center for Sustainable Resource Science kn-affil= affil-num=12 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Brachypodium distachyon kn-keyword=Brachypodium distachyon en-keyword=monocotyledonous plant kn-keyword=monocotyledonous plant en-keyword=microbe-associated molecular pattern kn-keyword=microbe-associated molecular pattern en-keyword=time-series transcriptome analysis kn-keyword=time-series transcriptome analysis en-keyword=reactive oxygen species kn-keyword=reactive oxygen species en-keyword=pattern-triggered immunity kn-keyword=pattern-triggered immunity END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=18 article-no= start-page=2703 end-page=2709 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220915 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Colon Wall Thickness Measured Using Transabdominal Ultrasonography Is Useful for Detecting Mucosal Inflammation in Ulcerative Colitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective Transabdominal ultrasonography (TUS) is a non-invasive procedure that is reportedly useful for managing ulcerative colitis (UC) and assessing bowel wall thickness (BWT), the most common measure of mucosal inflammation. However, the exact range of BWT that reflects disease activity remains undetermined. The present study clarified the BWT due to disease activity by comparing the use of TUS in each segment of the colon versus using colonoscopy (CS) and determined the usefulness of TUS in patients with UC.Methods We divided the colon into five segments and measured the BWT using TUS. The results were then compared to the Mayo endoscopic subscore (MES) classification to determine the accuracy of BWT measurement.Patients Eighty patients with UC who underwent TUS within 14 days of CS were retrospectively regis-tered.Results We evaluated a total of 268 images depicting each segment among 80 patients with UC. The BWT was positively correlated with endoscopic activity (0.69, p<0.0001). In each segment, the relationship be-tween a BWT>2 mm and an MES>0 had the highest sensitivity, specificity, and accuracy (0.85-1.00, 0.67-0.92, and 0.81-0.97, respectively).Conclusion This study concluded that TUS was a useful method of detecting an MES>0, which indicates the presence of inflammation and its location among UC patients. MES>0 was found to be highly accurate when a BWT>2 mm was considered positive. This non-invasive method may help control disease activity in patients with UC. en-copyright= kn-copyright= en-aut-name=TakaharaMasahiro en-aut-sei=Takahara en-aut-mei=Masahiro kn-aut-name=

Transitions in A?2ƒ®(0,0,0)?X?2ƒ°+(0,0,0) Band of Buffer-gas-cooled CaOH en-subtitle= kn-subtitle= en-abstract= kn-abstract=Calcium monohydroxide radical (CaOH) is receiving an increasing amount of attention from the astrophysics community as it is expected to be present in the atmospheres of hot rocky super-Earth exoplanets as well as interstellar and circumstellar environments. Here, we report the high-resolution laboratory absorption spectroscopy on low-J transitions in A ? 2 ƒ® ( 0 , 0 , 0 ) ? X ? 2 ƒ° + ( 0 , 0 , 0 ) band of buffer-gas-cooled CaOH. In total, 40 transitions out of the low-J states were assigned, including 27 transitions that have not been reported in previous literature. The determined rotational constants for both ground and excited states are in excellent agreement with previous literature, and the measurement uncertainty for the absolute transition frequencies was improved by more than a factor of 3. This will aid future interstellar, circumstellar, and atmospheric identifications of CaOH. The buffer-gas-cooling method employed here is a particularly powerful method to probe low-J transitions and is easily applicable to other astrophysical molecules. en-copyright= kn-copyright= en-aut-name=TakahashiYuiki en-aut-sei=Takahashi en-aut-mei=Yuiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BabaMasaaki en-aut-sei=Baba en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EnomotoKatsunari en-aut-sei=Enomoto en-aut-mei=Katsunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiramotoAyami en-aut-sei=Hiramoto en-aut-mei=Ayami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwakuniKana en-aut-sei=Iwakuni en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KumaSusumu en-aut-sei=Kuma en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TobaruReo en-aut-sei=Tobaru en-aut-mei=Reo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyamotoYuki en-aut-sei=Miyamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Division of Physics, Mathematics, and Astronomy, California Institute of Technology kn-affil= affil-num=2 en-affil=Department of Chemistry, Graduate School of Science, Kyoto University kn-affil= affil-num=3 en-affil=Department of Physics, University of Toyama kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=5 en-affil=Institute for Laser Science, University of Electro-Communications kn-affil= affil-num=6 en-affil=Atomic, Molecular and Optical Physics Laboratory, RIKEN kn-affil= affil-num=7 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=14999 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220902 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The association between hypothyroidism and proteinuria in patients with chronic kidney disease: a cross-sectional study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hypothyroidism is known to be correlated with kidney function and nephrotic range proteinuria. However, it is uncertain whether non-nephrotic proteinuria is associated with hypothyroidism. This study aimed to evaluate the association of proteinuria and hypothyroidism in chronic kidney disease (CKD) patients. We conducted a cross-sectional study composed of 421 CKD patients in a single hospital with measurements of 24-h urine protein excretion (UP) and thyroid function tests. Spearman correlation analysis revealed that 24-h Cr clearance (24hrCcr) was positively (r = 0.273, p < 0.001) and UP was negatively (r = - 0.207, p < 0.001) correlated with free triiodothyronine. Frequency distribution analysis stratified by CKD stage and UP for hypothyroidism revealed that the prevalence of hypothyroidism was higher among participants with higher CKD stage and nephrotic range proteinuria. Multivariate logistic regression analysis revealed that 24hrCcr and UP were significantly correlated with hypothyroidism (24hrCcr/10 mL/min decrease: odds ratio [OR], 1.29; 95% confidence interval [CI], 1.18-1.41; UP/1 g increase: OR, 1.10; 95% CI, 1.03-1.17). In addition, nephrotic range proteinuria, but not moderate UP (UP: 1.5-3.49 g/day), was significantly correlated with hypothyroidism compared to UP < 0.5 g/day. In summary, decreased kidney function and nephrotic range proteinuria, not non-nephrotic proteinuria, are independently associated with the hypothyroidism. en-copyright= kn-copyright= en-aut-name=Matsuoka-UchiyamaNatsumi en-aut-sei=Matsuoka-Uchiyama en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujiKenji en-aut-sei=Tsuji en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SangYizhen en-aut-sei=Sang en-aut-mei=Yizhen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakahashiKensaku en-aut-sei=Takahashi en-aut-mei=Kensaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FukushimaKazuhiko en-aut-sei=Fukushima en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakeuchiHidemi en-aut-sei=Takeuchi en-aut-mei=Hidemi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=InagakiKenichi en-aut-sei=Inagaki en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UchidaHaruhito A. en-aut-sei=Uchida en-aut-mei=Haruhito A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KitamuraShinji en-aut-sei=Kitamura en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SugiyamaHitoshi en-aut-sei=Sugiyama en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Chronic Kidney Disease and Cardiovascular Disease, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Human Resource Development of Dialysis Therapy for Kidney Disease, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=4 article-no= start-page=465 end-page=472 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Molecular-targeted Therapy for Metastatic Renal Cell Carcinoma As First-line Therapy: A Single Institution 13-year Experience en-subtitle= kn-subtitle= en-abstract= kn-abstract=We aimed to identify the role of first-line monotherapy with vascular endothelial growth factor receptor tyrosine kinase inhibitors (VEGFR-TKI) in patients with metastatic RCC. Eligible patients were categorized into three groups (favorable, intermediate, and poor risk) according to the International Metastatic RCC Database Consortium risk criteria. Overall survival (OS) was the primary endpoint. Survival was compared using the log-rank test. A total of 108 patients were retrospectively analyzed. The numbers of patients in the favorable-, intermediate-, and poor-risk groups were 32 (30%), 66 (61%), and 10 (9%), repestively. The median OS values in the entire cohort was 36 months (95% confidence interval [CI] 29-53). The median OS in the favorable, intermediate, and poor risk groups were 94 months (95% CI: 43-Not reached), 30 months (95% CI: 20-38), and 8 months (95% CI: 0-Not reached), respectively (p<0.05). Prior nephrectomy, clear cell histology, clinical T stage ?2, no metastasis at the time of diagnosis, nivolumab beyond first-line therapy, and objective response to VEGFR-TKIs were factors significantly prolonging OS on univariate analysis. VEGFR-TKI monotherapy as first-line therapy was an effective treatment option for patients with metastatic clear cell RCC with favorable risk. en-copyright= kn-copyright= en-aut-name=BekkuKensuke en-aut-sei=Bekku en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsugawaTakuji en-aut-sei=Tsugawa en-aut-mei=Takuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsuboiKazuma en-aut-sei=Tsuboi en-aut-mei=Kazuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NodaGaku en-aut-sei=Noda en-aut-mei=Gaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=InoueYousuke en-aut-sei=Inoue en-aut-mei=Yousuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MuraoWataru en-aut-sei=Murao en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=EbaraShin en-aut-sei=Ebara en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Urology, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=2 en-affil=Department of Urology, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=3 en-affil=Department of Urology, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=4 en-affil=Department of Urology, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=5 en-affil=Department of Urology, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=6 en-affil=Department of Urology, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=7 en-affil=Department of Urology, Hiroshima City Hiroshima Citizens Hospital kn-affil= en-keyword=metastatic renal cell carcinoma kn-keyword=metastatic renal cell carcinoma en-keyword=molecular-targeted therapy kn-keyword=molecular-targeted therapy en-keyword=immuno-checkpoint inhibitor kn-keyword=immuno-checkpoint inhibitor en-keyword=real-world setting kn-keyword=real-world setting END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=11 article-no= start-page=11047 end-page=11070 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220802 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Global stability of an age-structured infection model in vivo with two compartments and two routes en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this paper, for an infection age model with two routes, virus-to-cell and cell-to-cell, and with two compartments, we show that the basic reproduction ratio R-0 gives the threshold of the stability. If R-0 > 1, the interior equilibrium is unique and globally stable, and if R-0 <= 1, the disease free equilibrium is globally stable. Some stability results are obtained in previous research, but, for example, a complete proof of the global stability of the disease equilibrium was not shown. We give the proof for all the cases, and show that we can use a type reproduction number for this model. en-copyright= kn-copyright= en-aut-name=KajiwaraTsuyoshi en-aut-sei=Kajiwara en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SasakiToru en-aut-sei=Sasaki en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtaniYoji en-aut-sei=Otani en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Sciences, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=School of Engineering, Okayama University kn-affil= en-keyword=global stability kn-keyword=global stability en-keyword=two routes of infection kn-keyword=two routes of infection en-keyword=two compartments kn-keyword=two compartments en-keyword=type reproduction number kn-keyword=type reproduction number en-keyword=lyapunov functional kn-keyword=lyapunov functional END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=4 article-no= start-page=359 end-page=371 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Therapeutic Approaches Targeting miRNA in Systemic Lupus Erythematosus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Systemic lupus erythematosus (SLE) is a potentially fatal systemic autoimmune disease, and its etiology involves both genetic and environmental factors such as sex hormone imbalance, genetic predisposition, epigenetic regulation, and immunological factors. Dysregulation of microRNA (miRNA) is suggested to be one of the epigenetic factors in SLE. miRNA is a 22-nucleotide single-stranded noncoding RNA that contributes to post-transcriptional modulation of gene expression. miRNA targeting therapy has been suggested to be useful for the treatment of cancers and other diseases. Gene knockout and miRNA targeting therapy have been demonstrated to improve SLE disease activity in mice. However, these approaches have not yet reached the level of clinical application. miRNA targeting therapy is limited by the fact that each miRNA has multiple targets. In addition, the expression of certain miRNAs may differ among cell tissues within a single SLE patient. This limitation can be overcome by targeted delivery and chemical modifications. In the future, further research into miRNA chemical modifications and delivery systems will help us develop novel therapeutic agents for SLE. en-copyright= kn-copyright= en-aut-name=Hiramatsu-AsanoSumie en-aut-sei=Hiramatsu-Asano en-aut-mei=Sumie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=systemic lupus erythematosus kn-keyword=systemic lupus erythematosus en-keyword=miRNA kn-keyword=miRNA en-keyword=miRNA targeting therapy kn-keyword=miRNA targeting therapy END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220824 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Transplantation of modified human bone marrow-derived stromal cells affords therapeutic effects on cerebral ischemia in rats en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims SB623 cells are human bone marrow stromal cells transfected with Notch1 intracellular domain. In this study, we examined potential regenerative mechanisms underlying stereotaxic transplantation of SB623 cells in rats with experimental acute ischemic stroke. Methods We prepared control group, empty capsule (EC) group, SB623 cell group (SB623), and encapsulated SB623 cell (eSB623) group. Transient middle cerebral artery occlusion (MCAO) was performed on day 0, and 24 h after MCAO, stroke rats received transplantation into the envisioned ischemic penumbra. Modified neurological severity score (mNSS) was evaluated, and histological evaluations were performed. Results In the mNSS, SB623 and eSB623 groups showed significant improvement compared to the other groups. Histological analysis revealed that the infarction area in SB623 and eSB623 groups was reduced. In the eSB623 group, robust cell viability and neurogenesis were detected in the subventricular zone that increased significantly compared to all other groups. Conclusion SB623 cells with or without encapsulation showed therapeutic effects on ischemic stroke. Encapsulated SB623 cells showed enhanced neurogenesis and increased viability inside the capsules. This study reveals the mechanism of secretory function of transplanted SB623 cells, but not cell-cell interaction as primarily mediating the cells' functional benefits in ischemic stroke.

simultaneous administration of oxaliplatin and radiotherapy in colorectal cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Most cases of colorectal cancers (CRCs) are microsatellite stable (MSS), which frequently demonstrate lower response rates to immune checkpoint inhibitors (ICIs). RNA editing produces neoantigens by altering amino acid sequences. In this study, RNA editing was induced artificially by chemoradiation therapy (CRT) to generate neoantigens in MSS CRCs. Altogether, 543 CRC specimens were systematically analyzed, and the expression pattern of ADAR1 was investigated. In vitro and in vivo experiments were also performed. The RNA editing enzyme ADAR1 was upregulated in microsatellite instability-high CRCs, leading to their high affinity for ICIs. Although ADAR1 expression was low in MSS CRC, CRT including oxaliplatin (OX) treatment upregulated RNA editing levels by inducing ADAR1. Immunohistochemistry analyses showed the upregulation of ADAR1 in patients with CRC treated with CAPDX (capecitabine +OX) radiation therapy relative to ADAR1 expression in patients with CRC treated only by surgery (p <0.001). Compared with other regimens, CRT with OX effectively induced RNA editing in MSS CRC cell lines (HT29 and Caco2, p <0.001) via the induction of type 1 interferon-triggered ADAR1 expression. CRT with OX promoted the RNA editing of cyclin I, a neoantigen candidate. Neoantigens can be artificially induced by RNA editing via an OX-CRT regimen. CRT can promote proteomic diversity via RNA editing. en-copyright= kn-copyright= en-aut-name=KomatsuYasuhiro en-aut-sei=Komatsu en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1

second virial coefficients for hydrophobic interactions as a function of solute size en-subtitle= kn-subtitle= en-abstract= kn-abstract=To gain quantitative insight into how the overall strength of the hydrophobic interaction varies with the molecular size, we calculate osmotic second virial coefficients B for hydrophobic spherical molecules of different diameters ƒÐ in water based on molecular simulation with corrections to the finite-size and finite-concentration effects. It is shown that B?(<0) changes by two orders of magnitude greater as ƒÐ increases twofold and its solute-size dependence is best fit by a power law B å ƒÐ ƒ¿ with the exponent ƒ¿ ? 6, which contrasts with the cubic power law that the second virial coefficients of gases obey. It is also found that values of B for the solutes in a nonpolar solvent are positive but they obey the same power law as in water. A thermodynamic identity for B derived earlier [K. Koga, V. Holten, and B. Widom, J. Phys. Chem. B 119, 13391 (2015)] indicates that if B is asymptotically proportional to a power of ƒÐ, the exponent ƒ¿ must be equal to or greater than 6. en-copyright= kn-copyright= en-aut-name=NaitoHidefumi en-aut-sei=Naito en-aut-mei=Hidefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkamotoRyuichi en-aut-sei=Okamoto en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SumiTomonari en-aut-sei=Sumi en-aut-mei=Tomonari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KogaKenichiro en-aut-sei=Koga en-aut-mei=Kenichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220707 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Arthroscopic Meniscal Healing following Medial Meniscus Posterior Root Repair: A Comparison between Two Suture Materials en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recently, transtibial pullout repair of the medial meniscus (MM) posterior root tear (PRT) has become widely accepted and provides satisfactory clinical outcomes. Widening after cyclic loading or ultimate failure load using different suture materials and configurations has been studied. However, no study has compared the clinical outcomes using different suture materials. This study aimed to evaluate the clinical outcomes after performing MMPRT pullout repair using different suture materials. We hypothesized that better clinical outcomes would be achieved using ultra-high molecular weight polyethylene (UHMWPE) tape compared with a normal polyester suture. Thirty-seven patients who underwent MM posterior root repair between November 2019 and May 2020 were retrospectively investigated. Pullout repair was performed using a hollow no. 0 polyester suture (n?=?14) and UHMWPE tape (n?=?23). Clinical outcomes were assessed preoperatively and at 1 year postoperatively, using the Lysholm knee score, Knee Injury and Osteoarthritis Outcome Score, and visual analogue scale (VAS) pain score. The meniscal healing status was assessed using an arthroscopic scoring system (range: 0?10). All clinical scores were improved significantly in both groups. However, significantly higher meniscal healing scores and decreased VAS pain scores were observed in the UHMWPE group (7.3?}?0.9 and 7.7?}?11.3, respectively) than in the polyester group (5.6?}?2.1 and 18.4?}?18.6, respectively; p?<?0.01). Suture cut-out and loss of the root continuity were observed in some cases (three cases [21.4%] in the polyester suture group and one case [4.3%] in the UHMWPE tape group). Both suture materials led to satisfactory clinical outcomes at 1 year postoperatively, whereas the UHMWPE tape was useful for obtaining good meniscal healing and decreasing the VAS pain score. en-copyright= kn-copyright= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiranakaTakaaki en-aut-sei=Hiranaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZhangXiming en-aut-sei=Zhang en-aut-mei=Ximing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KintakaKeisuke en-aut-sei=Kintaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HigashiharaNaohiro en-aut-sei=Higashihara en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TamuraMasanori en-aut-sei=Tamura en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KodamaYuya en-aut-sei=Kodama en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KamatsukiYusuke en-aut-sei=Kamatsuki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=clinical outcome kn-keyword=clinical outcome en-keyword=medial meniscus kn-keyword=medial meniscus en-keyword=meniscal healing kn-keyword=meniscal healing en-keyword=posterior root tear kn-keyword=posterior root tear en-keyword=suture material kn-keyword=suture material END start-ver=1.4 cd-journal=joma no-vol=35 cd-vols= no-issue= article-no= start-page=71 end-page=80 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A posterior anchoring method decreases pullout suture translation of the medial meniscus posterior root repair during knee flexion en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The medial meniscus (MM) translates posteriorly and extrudes severely from the medial tibial plateau (MTP) during knee flexion in the MM posterior root tear (PRT) knee. Transtibial pullout repair of the MMPRT has been performed to regulate MM extrusion. This study aimed to evaluate pullout suture translation during knee flexion before and after posterior anchoring during pullout repair. We hypothesized that suture translation after posterior anchoring would be significantly decreased relative to that before posterior anchoring.
Methods: Thirty-five patients who underwent MM posterior root repair were prospectively investigated. Pullout repair was performed using two cinch sutures (outer and inner sutures) and posterior anchoring through the MM posterior horn and an additional bone tunnel on the MTP. The translation of the outer suture from 0 degrees to 90 degrees of knee flexion was measured and compared before and after posterior anchoring intraoperatively. The MM morphologic features were measured using preoperative magnetic resonance imaging, and the correlation between these values and outer suture translation was evaluated.
Results: The average outer suture translation after posterior anchoring (1.6 +/- 1.5 mm) was significantly decreased relative to that before posterior anchoring (2.5 +/- 1.7 mm, P < 0.01). No significant correlations were observed between the MM morphological features and outer suture translation.
Conclusions: The posterior anchoring method with an MM posterior root repair is useful in decreasing posterior translation of the pullout suture during knee flexion, which might have an advantage in preventing suture pullout from the repaired MM, leading to good clinical outcomes. en-copyright= kn-copyright= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiranakaTakaaki en-aut-sei=Hiranaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KintakaKeisuke en-aut-sei=Kintaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HigashiharaNaohiro en-aut-sei=Higashihara en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TamuraMasanori en-aut-sei=Tamura en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=4 article-no= start-page=1255 end-page=1262 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220520 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Medial meniscus posterior root repair influences sagittal length and coronal inclination of the anterior cruciate ligament: a retrospective study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose@Medial meniscus (MM) posterior root tears (PRTs) lead to abnormal kinematic changes in the knee and may induce pathological external rotation of the tibia during knee flexion. This study aimed to investigate changes in the length and inclination of the anterior cruciate ligament (ACL) after MM posterior root repair using magnetic resonance imaging (MRI).
Methods@This retrospective study included 44 patients who underwent MM posterior root repair between 2016 and 2019. Clinical outcomes were evaluated before and after surgery. MRI examinations were performed at 10 degrees/90 degrees of knee flexion preoperatively and 3 months postoperatively. The ACL length, proximal angle, and distal angle were determined using the sagittal view. MM extrusion and ACL inclination angle were determined using the coronal view.
Results@Clinical outcomes significantly improved 1 year after surgery. The postoperative ACL length (29.7 +/- 2.4 mm) and proximal angle (47.0 +/- 7.4 degrees) at 90 degrees of knee flexion decreased relative to the preoperative values (31.5 +/- 2.3 mm and 51.8 +/- 8.7 degrees, P < 0.01). The postoperative ACL inclination (64.9 +/- 5.6 degrees) at 10 degrees of knee flexion decreased relative to the preoperative value (69.7 +/- 5.6 degrees, P < 0.01).
Conclusion@Pathologically-stretched linear ACL at 90 degrees of knee flexion and a steep ACL inclination at 10 degrees of knee flexion could be reduced after MM posterior root repair. This suggests that pullout repair could restore MM function as a secondary stabilizer, thereby preventing meniscal and cartilage degeneration. en-copyright= kn-copyright= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KodamaYuya en-aut-sei=Kodama en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiranakaTakaaki en-aut-sei=Hiranaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KintakaKeisuke en-aut-sei=Kintaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KamatsukiYusuke en-aut-sei=Kamatsuki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= en-keyword=Anterior cruciate ligament kn-keyword=Anterior cruciate ligament en-keyword=Coronal inclination kn-keyword=Coronal inclination en-keyword=Knee kinematics kn-keyword=Knee kinematics en-keyword=Magnetic resonance imaging kn-keyword=Magnetic resonance imaging en-keyword=Medial meniscus kn-keyword=Medial meniscus en-keyword=Posterior root tear kn-keyword=Posterior root tear END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=3 article-no= start-page=247 end-page=253 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202206 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Analysis of Immunity against Measles, Mumps, Rubella, and Varicella Zoster in Adult Recipients of Allogeneic Hematopoietic Stem Cell Transplantation: A Single-Center Experience en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vaccine-preventable disease (VPD) infections are more severe in immunocompromised hosts. Vaccination against measles, mumps, rubella, and varicella zoster (VZV) (MMRV) is therefore recommended for hematopoietic stem cell transplantation (HCT) recipients. However, studies on adult HCT recipients with VPD infections are limited. At our institution, we have systematically conducted serological MMRV tests as a part of check-up examinations during long-term follow-up (LTFU) after HCT since 2015. This retrospective study aimed to evaluate changes in the serostatus between before and 2 years after allogeneic HCT. Among 161 patients, the pre-transplant seropositivity was 82.7% for measles, 86.8% for mumps, 84.2% for rubella, and 94.3% for VZV. Among 56 patients who underwent LTFU including serological MMRV tests at 2 years after HCT, the percentages maintaining seroprotective antibody levels for measles, mumps, rubella and VZV were 71.5% (40/56), 51.8% (29/56), 48.2% (27/56), and 60.7% (34/56), respectively. Vaccination was recommended for 22 patients, and 12 were vaccinated. Among the 12 vaccinated patients, rates of seroconversion were examined in 2-6 patients for each of the four viruses. They were 100% (3/3) for measles, 33.3% (1/3) for mumps, 50% (3/6) for rubella, and 0% (0/2) for VZV. Further studies are warranted to clarify the effect of vaccination in adult HCT recipients. en-copyright= kn-copyright= en-aut-name=YoshidaShohei en-aut-sei=Yoshida en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KamoiChihiro en-aut-sei=Kamoi en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KitamuraWataru en-aut-sei=Kitamura en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujiwaraHideaki en-aut-sei=Fujiwara en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AsadaNoboru en-aut-sei=Asada en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishimoriHisakazu en-aut-sei=Nishimori en-aut-mei=Hisakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujiiKeiko en-aut-sei=Fujii en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MatsuokaKen-ichi en-aut-sei=Matsuoka en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=vaccine-preventable disease kn-keyword=vaccine-preventable disease en-keyword=vaccination kn-keyword=vaccination en-keyword=allogeneic hematopoietic stem cell transplantation kn-keyword=allogeneic hematopoietic stem cell transplantation en-keyword=adult kn-keyword=adult END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=’_”XŠàŠ³ŽÒ‚É‚¨‚¯‚éAf’fA—\Œã—\‘ªƒ}[ƒJ[‚Æ‚µ‚Ä‚Ì×–EŠO¬–E“à‚ÌmicroRNAs‚Æ‚»‚Ì–ðŠ„‚Æ‚µ‚Ẳ”\« kn-title=Extracellular vesicle-shuttled miRNAs as a diagnostic and prognostic biomarker and their potential roles in gallbladder cancer patients en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=UetaEijiro en-aut-sei=Ueta en-aut-mei=Eijiro kn-aut-name=ã“c‰pŽŸ˜Y kn-aut-sei=ã“c kn-aut-mei=‰pŽŸ˜Y aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=‰ªŽR‘åŠw‘åŠw‰@ˆãŽ•–òŠw‘‡Œ¤‹†‰È END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=8 article-no= start-page=1115 end-page=1123 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220415 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinicopathological Characteristics of Superficial Barrett's Adenocarcinoma in a Japanese Population: A Retrospective, Multicenter Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective Although Barrett's adenocarcinoma (BA) remains a minor disease in Japan, its incidence has been gradually increasing. We analyzed the characteristics of BA in Japanese populations.
Methods We retrospectively reviewed medical records and analyzed the clinicopathological differences between short-segment Barrett's esophagus (SSBE) and long-segment Barrett's esophagus (LSBE), as well as metastasis. Local recurrence and metachronous lesions were analyzed only in patients who underwent endoscopic resection (ER).
Patients Consecutive patients who had pathological T1 BAs resected by ER or surgery from January 2003
Results A total of 168 patients were analyzed, including 139 with SSBE and 29 with LSBE. In total, 67% of the SSBE lesions and 32% of the LSBE lesions were located between 0 and 3 o'clock (p=0.0014). No patients who achieved pathological margin-free resection (pR0) and 17% of patients who did not achieve pR0 experienced local recurrence (p=0.0131). None of the patients without lymphovascular involvement, a poorly differentiated component, lesion size of >30 mm, and submucosal invasion of >500 mu m experienced metastasis. The 5-year cumulative incidence rate of metachronous BA after ER was 0% in patients with SSBE and 40% in patients with LSBE (p=0.0005).
Conclusion Superficial BA was likely to be detected at the right anterior wall of SSBE in the Japanese population. The risk for metachronous BA after ER was high in Japanese patients with LSBE, as in Western patients. en-copyright= kn-copyright= en-aut-name=HamadaKenta en-aut-sei=Hamada en-aut-mei=Kenta

kn-subtitle= en-abstract= kn-abstract=Background: Meningiomas are occasionally fed by pial blood supply (PBS). It is postulated that peritumoral flow void (PTFV), peritumoral brain edema (PTBE), and absence of an arachnoid plane (AP) are useful parameters for evaluating PBS. Purpose: To determine whether conventional magnetic resonance imaging (MRI) using a multiparametric scoring system (MSS) is a useful way to predict PBS. Material and Methods: Forty-six patients were included and divided: PBS and non-PBS groups. Differences between the groups in six parameters of MR imaging were analyzed: tumor size, tumor location, PTBE grade, AP grade, PTFV, and MIB1 labeling index (MIB1-LI) grade. Cutoff values were determined using receiver operating characteristic (ROC) curve analysis for the differentiation of both groups based on statistically significant parameters. All cases were scored as 1 (PBS) or 0 (non-PBS) for each parameter according to set thresholds. Individual scores were totaled for each case, yielding a combined score for each case to obtain a cutoff value using ROC curve analysis for the MSS. Results: Peritumoral brain edema grade, AP grade, PTFV, and MIB-LI grade were statistically associated with PBS. Receiver operating characteristic curve analyses showed that PTBE grade 3 or 4, AP grade 3 or 4, and PTFV positivity had the highest accuracy of 69%, 64%, and 68%, respectively. Regarding the MSS, a cutoff value of 2 had the highest accuracy of 71%; PBS diagnosis was indicated by at least two of the three parameters, namely, PTBE grade, AP grade, and PTFV. Conclusion: The MSS is a useful way to predict PBS in intracranial meningiomas on MRI. en-copyright= kn-copyright= en-aut-name=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=InoueSatoshi en-aut-sei=Inoue en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OdaWakako en-aut-sei=Oda en-aut-mei=Wakako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsusueEiji en-aut-sei=Matsusue en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurosurgery, Okayama City Hospital kn-affil= affil-num=3 en-affil=Department of Pathology, Okayama City Hospital kn-affil= affil-num=4 en-affil=Department of Radiology, Tottori Prefectural Central Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=pial blood supply kn-keyword=pial blood supply en-keyword=peritumoral brain edema kn-keyword=peritumoral brain edema en-keyword=arachnoid plane kn-keyword=arachnoid plane en-keyword=peritumoral flow void kn-keyword=peritumoral flow void en-keyword=magnetic resonance imaging kn-keyword=magnetic resonance imaging END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=2 article-no= start-page=111 end-page=119 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=2016127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Thrombolysis with Low-Dose Tissue Plasminogen Activator 3?4.5?h After Acute Ischemic Stroke in Five Hospital Groups in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Clinical data from Japan on the safety and real-world outcomes of alteplase (tPA) thrombolysis in the extended therapeutic window are lacking. The aim of this study was to assess the safety and real-world outcomes of tPA administered within 3-4.5 h of stroke onset. The study comprised consecutive acute ischemic stroke patients (n = 177) admitted across five hospitals between September 2012 and August 2014. Patients received intravenous tPA within <3 or 3-4.5 h of stroke onset. Endovascular therapy was used for tPA-refractory patients. In the 3-4.5 h subgroup (31.6 % of patients), tPA was started 85 min later than the <3 h group (220 vs. 135 min, respectively). However, outcome measures were not significantly different between the <3 and 3-4.5 h subgroups for recanalization rate (67.8 vs. 57.1 %), symptomatic intracerebral hemorrhage (2.5 vs. 3.6 %), modified Rankin Scale score of 0-1 at 3 months (36.0 vs. 23.4 %), and mortality (6.9 vs. 8.3 %). We present data from 2005 to 2012 using a therapeutic window <3 h showing comparable results. tPA following endovascular therapy with recanalization might be superior to tPA only with recanalization (81.0 vs. 59.1 %). Compared with administration within 3 h of ischemic stroke onset, tPA administration within 3-4.5 h of ischemic stroke onset in real-world stroke emergency settings at multiple sites in Japan is as safe and has the same outcomes. en-copyright= kn-copyright= en-aut-name=MoriharaRyuta en-aut-sei=Morihara en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KonoSyoichiro en-aut-sei=Kono en-aut-mei=Syoichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoKota en-aut-sei=Sato en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HishikawaNozomi en-aut-sei=Hishikawa en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OhtaYasuyuki en-aut-sei=Ohta en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamashitaToru en-aut-sei=Yamashita en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=DeguchiKentaro en-aut-sei=Deguchi en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ManabeYasuhiro en-aut-sei=Manabe en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakaoYoshiki en-aut-sei=Takao en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KashiharaKenichi en-aut-sei=Kashihara en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=InoueSatoshi en-aut-sei=Inoue en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KiriyamaHideki en-aut-sei=Kiriyama en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=AbeKoji en-aut-sei=Abe en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil= kn-affil= affil-num=5 en-affil=epartment of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=epartment of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=epartment of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Okayama National Hospital Medical Center kn-affil= affil-num=9 en-affil=Okayama National Hospital Medical Center kn-affil= affil-num=10 en-affil=Okayama National Hospital Medical Center kn-affil= affil-num=11 en-affil=Okayama National Hospital Medical Center kn-affil= affil-num=12 en-affil=Okayama National Hospital Medical Center kn-affil= affil-num=13 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Acute stroke kn-keyword=Acute stroke en-keyword=edaravone kn-keyword=edaravone en-keyword=endovascular treatment kn-keyword=endovascular treatment en-keyword=intracerebral hemorrhage kn-keyword=intracerebral hemorrhage en-keyword=recanalization kn-keyword=recanalization en-keyword=tissue-type plasminogen activator kn-keyword=tissue-type plasminogen activator END start-ver=1.4 cd-journal=joma no-vol=125 cd-vols= no-issue=46 article-no= start-page=12820 end-page=12831 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Theory of Gas Solubility and Hydrophobic Interaction in Aqueous Electrolyte Solutions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ion-specific effects on the solubility of nonpolar solutes and on the solute?solute hydrophobic interaction in aqueous electrolyte solutions are studied on the basis of a continuum theory that incorporates the excluded volume of the molecules using the four-component (water, cations, anions, and solutes) Boubl??k?Mansoori?Carnahan?Starling?Leland model and ion hydration (electrostriction) using the Born model. We examine how the ordering of ions in the salt effect on the solubility as measured by the Sechenov coefficient KS changes with varying sizes of ions and solutes. Our calculation reproduces the general trend of experimentally measured KS and also provides insight into the irregular behavior of KS for lithium ion. The correlation between KS and the salt effect on the hydrophobic interaction that has been pointed out earlier is accounted for by an explicit connection between KS and the salt-enhanced-association coefficient CI in the expansion of the second osmotic virial coefficient B(ns) = B(0) ? CIns + ??? in powers of the salt density ns at fixed pressure and temperature. The quadratic relation is derived for ions and solutes that are not very large. en-copyright= kn-copyright= en-aut-name=OkamotoRyuichi en-aut-sei=Okamoto en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KogaKenichiro en-aut-sei=Koga en-aut-mei=Kenichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=111 cd-vols= no-issue= article-no= start-page=21 end-page=25 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Propagation characteristics and method of appropriate management of invasive alien species Iris pseudacorus L. kn-title=ŠO—ˆ…¶A•¨ƒLƒVƒ‡ƒEƒu‚Ì”ÉB“Á«‚Æ“KØ‚ÈŠÇ—–@ en-subtitle= kn-subtitle= en-abstract= kn-abstract=To establish a proposal for a guiding principle supporting appropriate management of Iris pseudacorus L., which had been used as an important vegetation bank species until the Invasive Alien Species Act, this study investigated propaga-tion characteristics.

In the 5 cm height top-cutting treatment, the flowers and fruits in the next year were significantly fewer. en-copyright= kn-copyright= en-aut-name=NakashimaYoshitaka en-aut-sei=Nakashima en-aut-mei=Yoshitaka kn-aut-name=’†“ˆ‰À‹M kn-aut-sei=’†“ˆ kn-aut-mei=‰À‹M aut-affil-num=1 ORCID= affil-num=1 en-affil=Course of Applied Plant Science, The Faculty of Agriculture, Okayama University kn-affil=‰ªŽR‘åŠw”_Šw•”@‰ž—pA•¨‰ÈŠwƒR[ƒX en-keyword=Iris pseudacorus L. kn-keyword=Iris pseudacorus L. en-keyword=invasive alien species kn-keyword=invasive alien species en-keyword=propagation characteristics kn-keyword=propagation characteristics en-keyword=flood tolerance kn-keyword=flood tolerance END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=1 article-no= start-page=78 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220122 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Large flexion contracture angle predicts tight extension gap during navigational posterior stabilized-type total knee arthroplasty with the pre-cut technique: a retrospective study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
This study aimed to determine the predictors of tight extension gap (EG) compared with the flexion gap (FG) during navigational posterior stabilized-type total knee arthroplasty using the pre-cut technique.

Methods Nineteen patients with tight EG (defined as FG-EG >= 2 mm after pre-cut; group T) and 84 patients with an approximately equal gap (defined as FG-EG = 0-1 mm after pre-cut; group E) were enrolled. Medial tibial slope angle, hip knee ankle angle, flexion contracture angle, and active maximum flexion angle were compared between the two groups.

Results The multivariate logistic regression model indicated that the probability of tight EG increased with flexion contracture angle (odds ratio, 1.13; 95% confidence interval 1.05-1.20; P <= 0.001). According to the receiver operating characteristic analysis, the flexion contracture angle cut-off value associated with tight EG was 15.0 degrees (sensitivity, 85%; specificity, 78%).

Conclusion This study demonstrated that a large flexion contracture angle (cut-off 15.0 degrees) was associated with tight EG after pre-cut osteotomy during posterior stabilized-type total knee arthroplasty. Awareness of this risk factor may help improve preoperative predictability of tight EGs and preparedness for additional procedures, such as soft tissue release or capsulotomy, to correct them. en-copyright= kn-copyright= en-aut-name=HiranakaTakaaki en-aut-sei=Hiranaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyazawaShinichi en-aut-sei=Miyazawa en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KodamaYuya en-aut-sei=Kodama en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KamatsukiYusuke en-aut-sei=Kamatsuki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MasudaShin en-aut-sei=Masuda en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KintakaKeisuke en-aut-sei=Kintaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= en-keyword=Total knee arthroplasty kn-keyword=Total knee arthroplasty en-keyword=Extension gap kn-keyword=Extension gap en-keyword=Flexion gap kn-keyword=Flexion gap en-keyword=Predictor kn-keyword=Predictor en-keyword=Navigation system kn-keyword=Navigation system END start-ver=1.4 cd-journal=joma no-vol=407 cd-vols= no-issue=2 article-no= start-page=871 end-page=877 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=2022112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Surgical technique of suprapancreatic D2 lymphadenectomy focusing on the posterior hepatic plexus for advanced gastric cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose
Although D2 lymphadenectomy is currently considered a standard procedure for advanced gastric cancer (GC) worldwide, there is room for discussion about the appropriate range of suprapancreatic D2 lymphadenectomy. Focusing on the posterior hepatic plexus (PHP), which is not well recognized, we developed a surgical technique of suprapancreatic D2 lymphadenectomy, which we have called PHP-D2, and its short-term and long-term efficacies were evaluated in comparison with non-PHP-D2.

Methods
GC patients who underwent distal gastrectomy with D2 lymphadenectomy between July 2006 and May 2013 were enrolled, from which patients who had peritoneal metastasis and/or were peritoneal cytology-positive during surgery were excluded. Their medical records were retrospectively reviewed.

Results
Ninety-two patients (non-PHP-D2: 48, PHP-D2: 44) were enrolled. Shorter operation time (330 min vs 275 min, p?
Conclusion
PHP-D2 was a safe and feasible procedure that had the potential to reduce lymphatic recurrence, and it can be a standard procedure of D2 lymphadenectomy for advanced GC. en-copyright= kn-copyright= en-aut-name=KanayaNobuhiko en-aut-sei=Kanaya en-aut-mei=Nobuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KurodaShinji en-aut-sei=Kuroda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KakiuchiYoshihiko en-aut-sei=Kakiuchi en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakedaSho en-aut-sei=Takeda en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KikuchiSatoru en-aut-sei=Kikuchi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshidaRyuichi en-aut-sei=Yoshida en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UmedaYuzo en-aut-sei=Umeda en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TeraishiFuminori en-aut-sei=Teraishi en-aut-mei=Fuminori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NishizakiMasahiko en-aut-sei=Nishizaki en-aut-mei=Masahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KagawaShunsuke en-aut-sei=Kagawa en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=12 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Gastric cancer kn-keyword=Gastric cancer en-keyword=D2 lymphadenectomy kn-keyword=D2 lymphadenectomy en-keyword=Suprapancreatic lymphadenectomy kn-keyword=Suprapancreatic lymphadenectomy en-keyword=Posterior hepatic plexus kn-keyword=Posterior hepatic plexus en-keyword=Distal gastrectomy kn-keyword=Distal gastrectomy END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=13 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Estimation of periodontal pocket surface area in small to medium dogs: a proof-of-concept study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Periodontal disease is the most common dental disease in dogs. Although the systemic effects of periodontal disease have not been clarified in veterinary science, it is necessary to evaluate the effects of periodontal disease in clinical trials in the future. There have been a few clinical attempts made, however, to assess the severity of periodontal inflammation and its impact on the systemic health of dogs. Meanwhile, in the field of dentistry for humans, the periodontal inflamed surface area (PISA) and periodontal epithelial surface area (PESA) have been used to quantitatively assess the degree of periodontal disease affecting a single tooth as well as the overall extent of periodontitis. Recent studies have also suggested the use of these assessments to examine the relationship between periodontal inflammation and systemic health.

Results
The estimation formula for a dog's periodontal pocket surface area (PPSA), an alternative to PISA and PESA in humans, was established using body weight and periodontal pocket depth. Actual values were measured using extracted teeth from various dog breeds and sizes (2.3-25.0 kg of body weight) to obtain universal regression equations for PPSA. Altogether, 625 teeth from 73 dogs of 16 breeds were extracted and subsequently analyzed for morphological information. PPSA was measured in 61 dogs of 10 breeds with periodontal disease using the established estimation formulas, and the correlation between PPSA and preoperative blood chemistry data was analyzed accordingly. A strong correlation was found between PPSA and serum globulin (r = 0.71) while moderate correlations were found for C-reactive protein (r = 0.54) and serum albumin (r = -0.51).

Conclusions
Estimation formulas using body weight and the 6-point probing depth were established for determining PPSA. Direct correlations between PPSA and several blood test results were observed in the study sample. Taken together, these results suggest that PPSA could be useful for evaluating the effects of periodontitis on systemic conditions in dogs. en-copyright= kn-copyright= en-aut-name=TamuraKazuya en-aut-sei=Tamura en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Tokuzen-TaiMasako en-aut-sei=Tokuzen-Tai en-aut-mei=Masako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SiddiquiYasir Dilshad en-aut-sei=Siddiqui en-aut-mei=Yasir Dilshad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Tamura-NaitoHitomi en-aut-sei=Tamura-Naito en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NagaharaYoshiharu en-aut-sei=Nagahara en-aut-mei=Yoshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Hatanaka-TakeuchiKazu en-aut-sei=Hatanaka-Takeuchi en-aut-mei=Kazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamamotoTadashi en-aut-sei=Yamamoto en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Pathophysiology?Periodontal Science, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Periodontics and Endodontics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pathophysiology?Periodontal Science, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Periodontics and Endodontics, Okayama University Hospital kn-affil= affil-num=5 en-affil=Nagahara Animal Hospital kn-affil= affil-num=6 en-affil=Department of Periodontics and Endodontics, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Pathophysiology?Periodontal Science, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Pathophysiology?Periodontal Science, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Dog kn-keyword=Dog en-keyword=Periodontitis kn-keyword=Periodontitis en-keyword=Periodontal pocket surface area kn-keyword=Periodontal pocket surface area en-keyword=Estimation method kn-keyword=Estimation method en-keyword=Periodontology kn-keyword=Periodontology END start-ver=1.4 cd-journal=joma no-vol=100 cd-vols= no-issue=40 article-no= start-page=e27520 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211008 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Scoring systems for differentiating gastrointestinal stromal tumors and schwannomas from leiomyomas in the stomach en-subtitle= kn-subtitle= en-abstract= kn-abstract=There is no practical predictive model for the diagnosis of gastrointestinal stromal tumors (GISTs). To establish a practical predictive model for the diagnosis of subepithelial lesions in the stomach, we reviewed patients with GISTs (n = 89), schwannomas (n = 7), and leiomyomas (n = 28). The tumor was more frequently found along the gastric cardia in the leiomyoma group (57.1%) than in the GIST/schwannoma group (2.1%, P < .01). Contrast enhancement (57.3% vs 0%, P < .01) and intra-tumoral necrosis (34.4% vs 0.0%, P < .01) were more frequently observed in the GIST/schwannoma group than in the leiomyoma group. On endoscopic ultrasonography, 58.3% of GISTs/schwannomas showed uneven echogenicity, whereas the echogenicity was uneven in 21.4% of leiomyomas (P < .01). There were no differences between the tumor color and the presence or absence of ulcer formation, tumor bleeding, irregularity of the tumor margin, cystic spaces, and hyperechoic spots between the 2 groups. Based on these results, we developed a 2-step diagnostic algorithm for GISTs/schwannomas. The first step comprises 1 endoscopic feature: a cardiac or non-cardiac location. Tumors with a cardiac location were judged as leiomyomas and those with a non-cardiac location were judged as GISTs/schwannomas, with 96.9% sensitivity and 57.1% specificity for GIST/schwannoma diagnosis. The second step comprises a combination of endoscopic (non-cardiac location), radiologic (positive contrast enhancement and intra-tumoral necrosis), and endosonographic (uneven echogenicity) features for a total of 4 points. We assigned 1 point to each feature. Tumors with scores of 2 to 4 were judged as GISTs/schwannomas, with 81.3% sensitivity and 92.9% specificity for GIST/schwannoma diagnosis. Our predictive model will be a practical guide for the management of gastric subepithelial lesions. en-copyright= kn-copyright= en-aut-name=OkanoueShotaro en-aut-sei=Okanoue en-aut-mei=Shotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatomiTakuya en-aut-sei=Satomi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HamadaKenta en-aut-sei=Hamada en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakaeHiroyuki en-aut-sei=Sakae en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AbeMakoto en-aut-sei=Abe en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KonoYoshiyasu en-aut-sei=Kono en-aut-mei=Yoshiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KanzakiHiromitsu en-aut-sei=Kanzaki en-aut-mei=Hiromitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KawaharaYoshiro en-aut-sei=Kawahara en-aut-mei=Yoshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Practical Gastrointestinal Endoscopy, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=gastrointestinal stromal tumors kn-keyword=gastrointestinal stromal tumors en-keyword=leiomyomas kn-keyword=leiomyomas en-keyword=schwannomas kn-keyword=schwannomas en-keyword=tumor location kn-keyword=tumor location END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=149 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211022 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Kinetics of the ancestral carbon metabolism pathways in deep-branching bacteria and archaea en-subtitle= kn-subtitle= en-abstract= kn-abstract=The origin of life is believed to be chemoautotrophic, deriving all biomass components from carbon dioxide, and all energy from inorganic redox couples in the environment. The reductive tricarboxylic acid cycle (rTCA) and the Wood-Ljungdahl pathway (WL) have been recognized as the most ancient carbon fixation pathways. The rTCA of the chemolithotrophic Thermosulfidibacter takaii, which was recently demonstrated to take place via an unexpected reverse reaction of citrate synthase, was reproduced using a kinetic network model, and a competition between reductive and oxidative fluxes on rTCA due to an acetyl coenzyme A (ACOA) influx upon acetate uptake was revealed. Avoiding ACOA direct influx into rTCA from WL is, therefore, raised as a kinetically necessary condition to maintain a complete rTCA. This hypothesis was confirmed for deep-branching bacteria and archaea, and explains the kinetic factors governing elementary processes in carbon metabolism evolution from the last universal common ancestor. en-copyright= kn-copyright= en-aut-name=SumiTomonari en-aut-sei=Sumi en-aut-mei=Tomonari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HaradaKouji en-aut-sei=Harada en-aut-mei=Kouji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Computer Science and Engineering, Toyohashi University of Technology kn-affil= END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=10 article-no= start-page=607 end-page=618 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Spinal Surgery after Bilateral Subthalamic Stimulation for Patients with Parkinson's Disease: A Retrospective Outcome Analysis of Pain and Functional Control en-subtitle= kn-subtitle= en-abstract= kn-abstract=Parkinson's disease (PD) patients often suffer from spinal diseases requiring surgeries, although the risk of complications is high. There are few reports on outcomes after spinal surgery for PD patients with deep brain stimulation (DBS). The objective of this study was to explore the data on spinal surgery for PD patients with precedent DBS. We evaluated 24 consecutive PD patients with 28 spinal surgeries from 2007 to 2017 who received at least a 2-year follow-up. The characteristics and outcomes of PD patients after spinal surgery were compared to those of 156 non-PD patients with degenerative spinal diseases treated in 2013-2017. Then, the characteristics, outcomes, and spinal alignment of PD patients receiving DBS were analyzed in degenerative spinal/ lumbar diseases. The mean age at the time of spinal surgery was 68 years. The Hoehn and Yahr score regarding PD was stage 1 for 8 patients, stage 2 for 2 patients, stage 3 for 8 patients, stage 4 for 10 patients, and stage 5 for 0 patient. The median preoperative L-DOPA equivalent daily dose was 410 mg. Thirteen patients (46%) received precedent subthalamic nucleus (STN) DBS. Lumbar lesions with pain were common, and operation and anesthesia times were long in PD patients. Pain and functional improvement of PD patients persisted for 2 years after surgery with a higher complication rate than for non-PD patients. PD patients with STN DBS maintained better lumbar lordosis for 2 years after spinal surgery. STN DBS significantly maintained spinal alignment with subsequent pain and functional amelioration 2 years after surgery. The outcomes of spinal surgery for PD patients might be favorably affected by thorough treatment for PD including DBS. en-copyright= kn-copyright= en-aut-name=UmakoshiMichiari en-aut-sei=Umakoshi en-aut-mei=Michiari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorimotoJun en-aut-sei=Morimoto en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MuraiSatoshi en-aut-sei=Murai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SasakiTatsuya en-aut-sei=Sasaki en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KamedaMasahiro en-aut-sei=Kameda en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KinKyohei en-aut-sei=Kin en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyoshiYasuyuki en-aut-sei=Miyoshi en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurosurgery, Kawasaki Medical School General Medical Center kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=abnormal posture kn-keyword=abnormal posture en-keyword=lumbago kn-keyword=lumbago en-keyword=neuromodulation kn-keyword=neuromodulation en-keyword=pain kn-keyword=pain en-keyword=spinal alignment kn-keyword=spinal alignment END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=882 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211016 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relationship between clinical outcomes and nerve conduction studies before and after surgery in patients with carpal tunnel syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Nerve conduction study (NCS) is the only useful test for objective assessment of carpal tunnel syndrome (CTS). However, the relationship between pre- and postoperative NCS and clinical outcomes was unclear. This study aimed to determine whether pre- and postoperative (6?months) NCS could predict patient-oriented and motor outcomes (6 and 12?months postoperatively) in patients with CTS.

Method
Of the 85 patients with CTS, 107 hands were analyzed from March 2011 to March 2020. All patients underwent open carpal tunnel release and were examined using the disabilities of the arm, shoulder and hand (DASH) questionnaire and grip strength (GS) preoperatively and 6 and 12?months postoperatively. Moreover, NCS was examined preoperatively and 6?months postoperatively. Distal motor latency (DML) and sensory conduction velocity (SCV) were the parameters used for NCS. The correlation coefficient between NCS and DASH or GS was calculated. A receiver operating characteristic curve was utilized to determine the NCS threshold value to predict DASH and GS improvement.

Results
The average scores of GS preoperatively and 6 and 12?months postoperatively were 21.3, 22.3, and 22.8, respectively. On the other hand, the average scores of DASH preoperatively and 6 and 12?months postoperatively were 28.8, 18.3, and 12.2, respectively. The average NCS scores (DML and SCV) preoperatively/6?months postoperatively were 7.3/5.4 and 27.8/36.7, respectively. Preoperative NCS did not correlate with DASH and GS. Postoperative SCV correlated with the change in grip strength (6?12?months, r?=?0.67; 0?12?months, r?=?0.60) and DASH (0?12?months, r?=?0.77). Moreover, postoperative DML correlated with the change in DASH (6?12?months, r?=???0.33; 0?12?months, r?=???0.59). The prediction for the improvement of GS/DASH achieved a sensitivity of 50.0%/66.7% and a specificity of 100%/100%, at an SCV cutoff score of 38.5/45.0 or above. The prediction for improvement of GS/DASH achieved a sensitivity of 83.3%/66.7% and a specificity of 100%/66.7% at a DML cutoff score of 4.4/4.4 or below.

Conclusion
NCS at 6?months postoperatively can be used to predict the improvement of clinical outcome after 6?months postoperatively in patients with CTS. en-copyright= kn-copyright= en-aut-name=IseMasato en-aut-sei=Ise en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoTaichi en-aut-sei=Saito en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatayamaYoshimi en-aut-sei=Katayama en-aut-mei=Yoshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakaharaRyuichi en-aut-sei=Nakahara en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShimamuraYasunori en-aut-sei=Shimamura en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HamadaMasanori en-aut-sei=Hamada en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SendaMasuo en-aut-sei=Senda en-aut-mei=Masuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Sports Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Carpal tunnel syndrome kn-keyword=Carpal tunnel syndrome en-keyword=Nerve conduction study kn-keyword=Nerve conduction study en-keyword=The disability of the arm kn-keyword=The disability of the arm en-keyword=shoulder and hand questionnaire kn-keyword=shoulder and hand questionnaire en-keyword=Clinical outcomes kn-keyword=Clinical outcomes END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=1 article-no= start-page=187 end-page=190 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Symbolic powers of monomial ideals en-subtitle= kn-subtitle= en-abstract= kn-abstract=Let K be a field and consider the standard grading on A = K[X1, ... ,Xd].

Methods We retrospectively assessed 5 tiger vertebrae ex vivo and 16 human tibiae in vivo. Seven-pattern and four-pattern resolution imaging were performed on tiger vertebra using CRCT, UHRCT, and micro-CT, and on human tibiae using UHRCT. We measured six microarchitectural parameters: volumetric bone mineral density (vBMD), trabecular bone volume fraction (bone volume/total volume, BV/TV), trabecular thickness (Tb.Th), trabecular number (Tb.N), trabecular separation (Tb.Sp), and connectivity density (ConnD). Comparisons between different imaging resolutions were performed using Tukey or Dunnett T3 test. Results The vBMD, BV/TV, Tb.N, and ConnD parameters showed an increasing trend, while Tb.Sp showed a decreasing trend both ex vivo and in vivo. Ex vivo, UHRCT at the two highest resolutions (1024- and 2048-matrix imaging with 0.25-mm slice thickness) and CRCT showed significant differences (p <= 0.047) in vBMD (51.4 mg/cm(3) and 63.5 mg/cm(3)versus 20.8 mg/cm(3)), BV/TV (26.5% and 29.5% versus 13.8 %), Tb.N (1.3 l/mm and 1.48 l/mm versus 0.47 l/mm), and ConnD (0.52 l/mm(3) and 0.74 l/mm(3)versus 0.02 l/mm(3), respectively). In vivo, the 512- and 1024-matrix imaging with 0.25-mm slice thickness showed significant differences in Tb.N (0.38 l/mm versus 0.67 l/mm, respectively) and ConnD (0.06 l/mm(3)versus 0.22 l/mm(3), respectively). Conclusions We observed characteristic trends in microarchitectural parameters and demonstrated the potential utility of applying UHRCT for microarchitectural analysis. en-copyright= kn-copyright= en-aut-name=InaiRyota en-aut-sei=Inai en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakaharaRyuichi en-aut-sei=Nakahara en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorimitsuYusuke en-aut-sei=Morimitsu en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AkagiNoriaki en-aut-sei=Akagi en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MarukawaYouhei en-aut-sei=Marukawa en-aut-mei=Youhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsushitaToshi en-aut-sei=Matsushita en-aut-mei=Toshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanakaTakashi en-aut-sei=Tanaka en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TadaAkihiro en-aut-sei=Tada en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NasuYoshihisa en-aut-sei=Nasu en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NishidaKeiichiro en-aut-sei=Nishida en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=KanazawaSusumu en-aut-sei=Kanazawa en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Medical School kn-affil= affil-num=2 en-affil=Intelligent Orthopaedic System Development, Okayama University Medical School kn-affil= affil-num=3 en-affil=Devision of Radiology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=4 en-affil=Devision of Radiology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Medical School kn-affil= affil-num=6 en-affil=Devision of Radiology, Medical Support Department, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Radiology, Okayama University Medical School kn-affil= affil-num=8 en-affil=Department of Radiology, Okayama University Medical School kn-affil= affil-num=9 en-affil=Department of Radiology, Okayama University Medical School kn-affil= affil-num=10 en-affil=Medical materials for musculoskeletal reconstruction, Okayama University Medical School kn-affil= affil-num=11 en-affil=Orthopaedic Surgery, Okayama University Medical School kn-affil= affil-num=12 en-affil=Orthopaedic Surgery, Okayama University Medical School kn-affil= affil-num=13 en-affil=Department of Radiology, Okayama University Medical School kn-affil= en-keyword=Osteoporosis kn-keyword=Osteoporosis en-keyword=Bone density kn-keyword=Bone density en-keyword=Tomography (x-ray computed) kn-keyword=Tomography (x-ray computed) en-keyword=X-ray microtomography kn-keyword=X-ray microtomography END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=10 article-no= start-page=2920 end-page=2930 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210521 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Local oncolytic adenovirotherapy produces an abscopal effect via tumor-derived extracellular vesicles en-subtitle= kn-subtitle= en-abstract= kn-abstract=Extracellular vesicles (EVs) play important roles in various intercellular communication processes. The abscopal effect is an interesting phenomenon in cancer treatment, in which immune activation is generally considered a main factor. We previously developed a telomerase-specific oncolytic adenovirus, Telomelysin (OBP-301), and occasionally observed therapeutic effects on distal tumors after local treatment in immunodeficient mice. In this study, we hypothesized that EVs may be involved in the abscopal effect of OBP-301. EVs isolated from the supernatant of HCT116 human colon carcinoma cells treated with OBP-301 were confirmed to contain OBP-301, and they showed cytotoxic activity (apoptosis and autophagy) similar to OBP-301. In bilateral subcutaneous HCT116 and CT26 tumor models, intratumoral administration of OBP-301 produced potent antitumor effects on tumors that were not directly treated with OBP-301, involving direct mediation by tumor-derived EVs containing OBP-301. This indicates that immune activation is not the main factor in this abscopal effect. Moreover, tumor-derived EVs exhibited high tumor tropism in orthotopic HCT116 rectal tumors, in which adenovirus E1A and adenovirus type 5 proteins were observed in metastatic liver tumors after localized rectal tumor treatment. In conclusion, local treatment with OBP-301 has the potential to produce abscopal effects via tumor-derived EVs. en-copyright= kn-copyright= en-aut-name=KakiuchiYoshihiko en-aut-sei=Kakiuchi

en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
During transtibial pullout repair of medial meniscus (MM) posterior root tears (MMPRTs), accurate tibial tunnel creation within the anatomic MM posterior root attachment seems critical. This study aimed to evaluate the tibial tunnel position created by a newly-developed Precision guide during pullout repair of MMPRTs.
Methods
In 40 patients who underwent transtibial pullout repairs, the tibial tunnel was created using the Unicorn Meniscal Root (UMR) (n?=?20) or Precision guide (n?=?20). Three-dimensional computed tomography images of the tibial surface were evaluated postoperatively, using Tsukada's measurement method. The expected anatomic center of the MM posterior root attachment was defined as the center of three tangential lines corresponding to anatomic bony landmarks. The expected anatomic center (AC) and the tibial tunnel center (TC) were evaluated using the percentage-based posterolateral location on the tibial surface. The difference in the mediolateral and anteroposterior percentage distance between the AC and TC was calculated, as was the absolute distance between the AC and TC.
Results
The mean AC was located 77.4% posterior and 40.1% lateral. The mean TC was similar in the UMR and Precision guide groups. There was no significant difference in the mediolateral percentage distance (UMR 3.9% vs. Precision 3.6%, p?=?0.405), but a significant difference was observed in the anteroposterior percentage distance (UMR 3.5% vs. Precision 2.6%, p?=?0.031). The mean absolute distance between the AC and TC was 3.9?mm and 3.5?mm (UMR and Precision guide groups, respectively) (p?=?0.364).
Conclusions

Different methods are available to assess the healing status of repaired root for medial meniscus posterior root tears (MMPRT) using second-look arthroscopy. However, few studies are comparing them or validating their usefulness. Therefore, it was hypothesized that the semi-quantitative arthroscopic score might correlate more with 1-year clinical outcomes in patients with MMPRT than the qualitative evaluation.
Methods
Data of 61 patients who underwent MMPRT pullout repair and second-look arthroscopy were retrospectively evaluated. The semi-quantitative arthroscopic scoring system was divided into three evaluation criteria: scores from 0 to 10 points include the width of the bridging tissue, stability of the repaired root, and synovial coverage. The qualitative evaluation was classified into 4 status; complete healing, lax healing, scar tissue healing, and failed healing according to the stability and mobility of the repaired root. Multivariate linear regression analyses were used to identify predictors of 1-year postoperative clinical outcomes, including Knee Injury and Osteoarthritis Outcome, Lysholm, or International Knee Documentation Committee scores. Spearman's correlation analysis was used to analyze the correlation between second-look arthroscopic score/qualitative evaluation and 1-year postoperative clinical outcomes. In addition, the optimal cutoff point of semi-quantitative arthroscopic score was determined by receiver operating characteristic (ROC) curve. The Mann?Whitney U test was used to compare clinical outcomes between patients with semi-quantitative arthroscopic scores ?8 and scores <8.
Results
All clinical scores significantly improved at 1 year postoperatively. A good correlation was observed between the semi-quantitative score and clinical scores, but none between qualitative evaluation and clinical scores. The optimal cutoff point of semi-quantitative second-look arthroscopic score was 8 points. Significantly, better clinical outcomes were observed in patients with semi-quantitative scores ?8 points.
Conclusions
All 1-year postoperative clinical scores were significantly improved. The semi-quantitative arthroscopic scores correlate more with 1-year clinical outcomes in patients with MMPRT than the qualitative evaluation.

To evaluate the feasibility of O-arm navigation of bilateral dual sacral-alar-iliac (SAI) screws compared with conventional bilateral single SAI and S1 pedicle screws for pelvic anchors in cases of adult spinal deformity.
Methods
This retrospective, comparative study included 39 patients who underwent corrective fusion using SAI screws from T10 to the pelvis. Patients were divided into 2 groups according to the number of SAI screws placed during adult spinal deformity surgery: single SAI screw (group S, 17 cases) and dual SAI screws (group D, 22 cases). The incidence of rod breakage, proximal junctional kyphosis, screw loosening, reoperation, and global alignment in each group was estimated. Postoperative patient-reported outcomes were measured using the Oswestry Disability Index, Japanese Orthopaedic Association Back Pain Evaluation Questionnaire, and visual analog scale.
Results
The incidence of SAI screw loosening was significantly lower in group D than in group S (23% vs. 65%, P?= 0.011). The rod breakage incidence was 0% and 12% in groups D and S, respectively (P?= 0.17). There were no significant differences in the postoperative global alignment and clinical outcomes between the 2 groups.
Conclusions
Dual SAI screws were associated with a significantly reduced incidence of screw loosening compared with single SAI screws. The bilateral dual SAI screws technique for pelvic anchors is feasible for the treatment of patients with adult spinal deformity. en-copyright= kn-copyright= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SonawaneSumeet en-aut-sei=Sonawane en-aut-mei=Sumeet kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=RuparelSameer en-aut-sei=Ruparel en-aut-mei=Sameer kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujiwaraYoshihiro en-aut-sei=Fujiwara en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AratakiShinya en-aut-sei=Arataki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamauchiTaro en-aut-sei=Yamauchi en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MisawaHaruo en-aut-sei=Misawa en-aut-mei=Haruo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopaedic surgery, Okayama Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic surgery, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic surgery, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic surgery, Okayama Rosai Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic surgery, Okayama University Hospital kn-affil= en-keyword=dual SAI screws kn-keyword=dual SAI screws en-keyword= adult spine deformity kn-keyword= adult spine deformity en-keyword= spinopelvic fixation kn-keyword= spinopelvic fixation en-keyword=navigation surgery kn-keyword=navigation surgery END start-ver=1.4 cd-journal=joma no-vol=101 cd-vols= no-issue= article-no= start-page=103297 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Germplasm evaluation for crop improvement: Analysis of grain quality and cadmium accumulation in barley en-subtitle= kn-subtitle= en-abstract=Evaluating genetic variation in barley (Hordeum vulgare) germplasm, combined with genome-wide genotyping, is vital for identifying genes controlling important grain-quality traits.

For example, in addition to traditional grain quality properties such as starch and protein contents, grain safety parameters such as heavy metal content, are important in the use of barley for human food and animal feed. A number of genes affecting grain quality have been identified by map-based cloning strategies and functionally analyzed by genetic transformation experiments. Moreover, germplasm evaluation yielded information that enabled the introgression of a key gene controlling grain cadmium accumulation into an elite barley cultivar, reducing the content of this heavy metal in grain. Genotyping of molecular markers and resequencing of germplasm accessions may provide information about how grain quality?related loci evolved and how the current allelic diversity was established. In this review, we describe germplasm resources for barley grain quality?related traits and the methods used to analyze the functions of genes controlling these traits, illustrating cadmium accumulation as an example. We also discuss future directions for the efficient identification of grain quality?related genes. en-copyright= kn-copyright= en-aut-name=SatoKazuhiro en-aut-sei=Sato en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaJian Feng en-aut-sei=Ma en-aut-mei=Jian Feng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Barley kn-keyword=Barley en-keyword=Core collection kn-keyword=Core collection en-keyword= Genome analysis kn-keyword= Genome analysis en-keyword=Genome-wide association study kn-keyword=Genome-wide association study END start-ver=1.4 cd-journal=joma no-vol=297 cd-vols= no-issue= article-no= start-page=101071 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A structural model for (GlcNAc)2 translocation via a periplasmic chitooligosaccharide-binding protein from marine Vibrio bacteria en-subtitle= kn-subtitle= en-abstract= kn-abstract=VhCBP is a periplasmic chitooligosaccharide-binding protein mainly responsible for translocation of the chitooligosaccharide (GlcNAc)2 across the double membranes of marine bacteria. However, structural and thermodynamic understanding of the sugar-binding/-release processes of VhCBP is relatively less. VhCBP displayed the greatest affinity toward (GlcNAc)2, with lower affinity for longer-chain chitooligosaccharides [(GlcNAc)3?4]. (GlcNAc)4 partially occupied the closed sugar-binding groove, with two reducing-end GlcNAc units extending beyond the sugar-binding groove and barely characterized by weak electron density. Mutation of three conserved residues (Trp363, Asp365, and Trp513) to Ala resulted in drastic decreases in the binding affinity toward the preferred substrate (GlcNAc)2, indicating their significant contributions to sugar binding. The structure of the W513A?(GlcNAc)2 complex in a ehalf-openf conformation unveiled the intermediary step of the (GlcNAc)2 translocation from the soluble CBP in the periplasm to the inner membrane?transporting components. Isothermal calorimetry data suggested that VhCBP adopts the high-affinity conformation to bind (GlcNAc)2, while its low-affinity conformation facilitated sugar release. Thus, chitooligosaccharide translocation, conferred by periplasmic VhCBP, is a crucial step in the chitin catabolic pathway, allowing Vibrio bacteria to thrive in oceans where chitin is their major source of nutrients. en-copyright= kn-copyright= en-aut-name=KitaokuYoshihito en-aut-sei=Kitaoku en-aut-mei=Yoshihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukamizoTamo en-aut-sei=Fukamizo en-aut-mei=Tamo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KumsaoadSawitree en-aut-sei=Kumsaoad en-aut-mei=Sawitree kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UbonbalPrakayfun en-aut-sei=Ubonbal en-aut-mei=Prakayfun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=RobinsonRobert C. en-aut-sei=Robinson en-aut-mei=Robert C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SugintaWipa en-aut-sei=Suginta en-aut-mei=Wipa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=School of Biomolecular Science and Engineering (BSE), Vidyasirimedhi Institute of Science and Technology (VISTEC) kn-affil= affil-num=2 en-affil=School of Biomolecular Science and Engineering (BSE), Vidyasirimedhi Institute of Science and Technology (VISTEC) kn-affil= affil-num=3 en-affil=School of Biomolecular Science and Engineering (BSE), Vidyasirimedhi Institute of Science and Technology (VISTEC) kn-affil= affil-num=4 en-affil=School of Biomolecular Science and Engineering (BSE), Vidyasirimedhi Institute of Science and Technology (VISTEC) kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=School of Biomolecular Science and Engineering (BSE), Vidyasirimedhi Institute of Science and Technology (VISTEC) kn-affil= END start-ver=1.4 cd-journal=joma no-vol=299 cd-vols= no-issue= article-no= start-page=117388 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Superposition of 532?nm and 1064?nm Wavelengths in Copper Micro-welding by Pulsed Nd:YAG Laser en-subtitle= kn-subtitle= en-abstract= kn-abstract=Unstable and low absorption of laser energy is experienced in copper welding at around 1000?nm wavelength. At 532?nm wavelength, there is stable and high laser absorption by copper. Past researches have shown that transitional processing condition between keyhole and heat conduction welding results in a stable micro-welding process characterized by good surface quality and deep penetration. In order to adapt laser welding to copper using pulsed Nd:YAG lasers, investigations of welding quality and efficiency were addressed. Processing was done under transitional processing condition between heat conduction and keyhole welding. Copper C1020 specimens were processed using superposed laser wavelengths of 1064?nm and 532?nm. Effects of irradiation delay and power density on the process were clarified by taking measurements of absorption rates and molten volumes, and by analyzing the weld beads. In addition, the dynamics of molten area and keyhole formation were investigated through three-dimensional FEM analysis. A stabilized laser absorption and increased molten volume was achieved by superposition using 532?nm laser of an appropriate high power density coupled with a short irradiation delay for the 1064?nm laser, which resulted in high-efficiency welding of copper. en-copyright= kn-copyright= en-aut-name=MainaMartin Ruthandi en-aut-sei=Maina en-aut-mei=Martin Ruthandi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkamotoYasuhiro en-aut-sei=Okamoto en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamadaKazuki en-aut-sei=Hamada en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkadaAkira en-aut-sei=Okada en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakashibaShin-ichi en-aut-sei=Nakashiba en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishiNorio en-aut-sei=Nishi en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Nontraditional Machining Laboratory, Okayama University kn-affil= affil-num=2 en-affil=Nontraditional Machining Laboratory, Okayama University kn-affil= affil-num=3 en-affil=Nontraditional Machining Laboratory, Okayama University kn-affil= affil-num=4 en-affil=Nontraditional Machining Laboratory, Okayama University kn-affil= affil-num=5 en-affil=Kataoka Corporation kn-affil= affil-num=6 en-affil=Kataoka Corporation kn-affil= END start-ver=1.4 cd-journal=joma no-vol=40 cd-vols= no-issue= article-no= start-page=100407 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211031 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Blood concentrations of tacrolimus upon conversion from rabeprazole to vonoprazan in renal transplant recipients: Correlation with cytochrome P450 gene polymorphisms en-subtitle= kn-subtitle= en-abstract= kn-abstract=We evaluated the impact of vonoprazan on blood concentrations of tacrolimus via a retrospective analysis of 52 renal transplant recipients who took tacrolimus and converted from rabeprazole to vonoprazan between August 2018 and September 2019. We compared tacrolimus trough levels upon conversion among groups that were classified based on cytochrome P450 (CYP) gene polymorphisms. CYP3A5 groups were heterozygous or homozygous for CYP3A5?1 and CYP3A5?3 alleles. CYP2C19 genotypes were classified as extensive (?1/?1), intermediate (?1/?2 and ?1/?3) or poor metabolizers (?2/?2, ?2/?3 and ?3/?3). Tacrolimus trough levels increased only 0.3?ng/mL upon conversion in the CYP3A5?3/?3 group: 5.8 [3.4-7.2] vs 6.1 [3.8-7.9]; p?=?0.06. No statistically significance changes in tacrolimus levels also occurred in the CYP3A5?1/?1 or CYP3A5?1/?3 groups. Subgroup analyses of CYP3A5?3/?3 demonstrated low changes for all three CYP2C19 subgroups: 5.2 [4.3-6.5] vs 6.2 [4.3-7.9]; p?=?0.07, 6.1 [3.4-7.2] vs 6.7 [4.6-7.9]; p?=?0.12 and 5.4 [3.6-6.5] vs 4.7 [3.8-6.3]; p?=?1.00, respectively. Conversion to vonoprazan thus resulted in little increase of tacrolimus trough levels, even in the group predicted to be most susceptible (CYP3A5?3/?3 and 2C19?1/?1), thus supporting the safety of concomitant use of vonoprazan with tacrolimus. en-copyright= kn-copyright= en-aut-name=WatariShogo en-aut-sei=Watari en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

kn-subtitle= en-abstract= kn-abstract=This study aimed to evaluate the disease severity and local immune responses in macrophage-depleted chicks with Eimeria tenella. Macrophages were reduced by intraperitoneal injection of a carrageenan solution at 12, 13, and 16 days old, whereas the control group received intraperitoneal phosphate-buffered saline. Both chick groups were orally inoculated with E. tenella sporulated oocysts at 14 days old. Feces were collected daily, which were then quantified for oocysts. The chicks were sacrificed on day 5, and the ceca were collected for histopathological observation. The gene expression levels were measured using real-time quantitative reverse transcription-polymerase chain reaction. Macrophage-depleted chicks have been observed to shed a significantly reduced number of fecal oocysts compared to the infected control group. The parasite burden score in cecum specimens of macrophage-depleted chicks was significantly lower than those of infected control on day 5 after infection. Furthermore, macrophage reduction yielded significantly lower cecum histopathological scores and CD4 expression than those of the infected control group. The expression of interleukin (IL)-18, IL-22, interferon-ƒÁ, and inducible nitric oxide synthase was also noted to be significantly upregulated in both infected control and macrophage-depleted chicks compared to uninfected chicks. IL-4, IL-13, IL-17, and perforin expressions were also higher with macrophage depletion than in both control groups. These results suggest that macrophages serve as an invasive gate or a transporting vehicle to the site of first merogony. Furthermore, mononuclear phagocytes may play an important role in local immune responses, thus contributing to parasite development during early E. tenella infection. en-copyright= kn-copyright= en-aut-name=HoDung Thi en-aut-sei=Ho en-aut-mei=Dung Thi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PhamHung Hoang Son en-aut-sei=Pham en-aut-mei=Hung Hoang Son kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AotaWataru en-aut-sei=Aota en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsubayashiMakoto en-aut-sei=Matsubayashi en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsujiNaotoshi en-aut-sei=Tsuji en-aut-mei=Naotoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HatabuToshimitsu en-aut-sei=Hatabu en-aut-mei=Toshimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Veterinary Science, Graduate School of Life and Environmental Sciences, Osaka Prefecture University kn-affil= affil-num=5 en-affil=Department of Parasitology and Tropical Medicine, Kitasato University School of Medicine kn-affil= affil-num=6 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Eimeria tenella kn-keyword=Eimeria tenella en-keyword=Local immune response kn-keyword=Local immune response en-keyword=Macrophage kn-keyword=Macrophage END start-ver=1.4 cd-journal=joma no-vol=240 cd-vols= no-issue= article-no= start-page=110321 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relationship between Eimeria tenella associated-early clinical signs and molecular changes in the intestinal barrier function en-subtitle= kn-subtitle= en-abstract= kn-abstract=The major clinical signs of coccidiosis in chickens due to Eimeria parasite are diarrhea and bloody feces. Previous studies showed that the impairment of the intestinal epithelial barrier and the elevation of the intestinal permeability are causes of clinical signs associated with coccidia challenges. Nevertheless, the information about molecular changes of the epithelial barrier at the early stage of the infection with a specific Eimeria species has not been mentioned. Hence, this study aims to elucidate the temporal relationships between epithelial barrier conditions and clinical signs in chickens infected with Eimeria tenella over the time from the earliest stages of infection.
White Leghorn chickens were inoculated with 1 ~ 104 oocysts of E. tenella. Thereafter the chickens were monitored for their daily clinical signs through observation, and between 5 dpi to 10 dpi, feces were collected for oocysts counting. Chickens were then administrated with fluorescein isothiocyanate-dextran (FITC-d) for gastrointestinal permeability test and tissues were collected each day for histopathological observation and total RNA extraction. Finally, the mRNA expression levels of the tight and adherens junction genes and cytokine genes were evaluated using the quantitative real-time polymerase chain reaction (qRT-PCR).
In this study, clinical signs such as diarrhea and bloody feces were observed concurrently from 3 to 8 dpi. Histopathology changes such as severe inflammation, hemorrhage, and epithelial desquamation were identified in the cecum specimens. The FITC-d level in the E. tenella-infected group was significantly higher than in the control group. In the infected group, the expression of claudin-2 gene was also upregulated, whereas the expressions of claudin-3 and E-cadherin genes were decreased as compared to the control group. These results implied that clinical signs of avian coccidiosis were associated with the intestinal barrier disruption via changes in expression levels of claudins and E-cadherin at the intestine. en-copyright= kn-copyright= en-aut-name=PhamHung Hoang Son en-aut-sei=Pham en-aut-mei=Hung Hoang Son kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsubayashiMakoto en-aut-sei=Matsubayashi en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsujiNaotoshi en-aut-sei=Tsuji en-aut-mei=Naotoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HatabuToshimitsu en-aut-sei=Hatabu en-aut-mei=Toshimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Veterinary Science, Graduate School of Life and Environmental Sciences, Osaka Prefecture University kn-affil= affil-num=3 en-affil=Department of Molecular and Cellular Parasitology, Kitasato University Graduate School of Medical Science kn-affil= affil-num=4 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Adherens junction kn-keyword=Adherens junction en-keyword=Bloody feces kn-keyword=Bloody feces en-keyword=Diarrhea kn-keyword=Diarrhea en-keyword=Eimeria tenella kn-keyword=Eimeria tenella en-keyword=Epithelial barrier kn-keyword=Epithelial barrier en-keyword=Tight junction kn-keyword=Tight junction END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=3 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021721 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=New field?in?field with two reference points method for whole breast radiotherapy: Dosimetric analysis and radiation?induced skin toxicities assessment en-subtitle= kn-subtitle= en-abstract= kn-abstract=The usefulness of the field?in?field with two reference points (FIF w/ 2RP) method, in which the dose reference points are set simultaneously at two positions in the irradiation field and the high?dose range is completely eliminated, was examined in the present study with the aim of decreasing acute skin toxicity in adjuvant breast radiotherapy (RT). A total of 573 patients with breast cancer who underwent postoperative whole breast RT were classified into 178 cases with wedge (W) method, 142 cases with field?in?field without 2 reference points (FIF w/o 2RP) method and 253 cases with FIF w/ 2RP method. Using the FIF w/ 2RP method, the high?dose range was the lowest among the three irradiation methods. The planning target volume (PTV) V105% and the breast PTV for evaluation (BPe) V105% decreased to 0.09 and 0.10%, respectively. The FIF w/ 2RP method vs. the FIF w/o 2RP method had a strong association (ā) with PTV V105% (ā=0.79; P<0.001) and BPe V105% (ā=0.76; P<0.001). The FIF w/ 2RP method had a significant impact on lowering the skin toxicity grade in weeks 3 and 4, and increasing the occurrence of skin toxicity grade 0. The FIF w/ 2RP method vs. the W method had a moderate association with skin toxicity grade at week 3 (ā=0.49; P<0.001). Using the FIF w/ 2RP method, the high?dose range V105% of the target decreased to 0%, and skin adverse events were decreased in conjunction. For patients with early?stage breast cancer, particularly patients with relatively small?sized breasts, the FIF w/ 2RP method may be an optimal irradiation method. en-copyright= kn-copyright=

Measurement Method for the Evaluation of Metatarsophalangeal Joint Dislocation of the Lesser Toe in Patients with Rheumatoid Arthritis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Dorsal dislocation of metatarsophalangeal (MTP) joints of the lesser toe frequently occurs in patients with rheumatoid arthritis (RA), and may cause painful and uncomfortable plantar callosities and ulceration. The current study examined the reliability and clinical relevance of a novel radiographic parameter (the MTP overlap distance [MOD]) in evaluating the severity of MTP joint dislocation. The subjects of the current study were 147 RA patients (276 feet; 1104 toes). MOD, defined as the overlap distance of the metatarsal head and the proximal end of the phalanx, was measured on plain radiographs. The relationship between the MOD and clinical complaints (forefoot pain and/or callosity formation) was analyzed to create a severity grading system. As a result, toes with callosities had a significantly larger MOD. ROC analysis revealed that the MOD had a high AUC for predicting an asymptomatic foot (-0.70) and callosities (0.89). MOD grades were defined as follows: grade 1, 0 <= MOD < 5 mm; grade 2, 5 <= MOD < 10 mm; and grade 3, MOD >= 10 mm. The intra- and inter-observer reliability of the MOD grade had high reproducibility. Furthermore, the MOD and MOD grade improved significantly after joint-preserving surgeries for lesser toe deformities. Our results suggest that MOD and MOD grade might be useful tools for the evaluation of deformities of the lesser toe and the effect of surgical intervention for MTP joints in patients with RA. en-copyright= kn-copyright= en-aut-name=OhashiHideki en-aut-sei=Ohashi en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishidaKeiichiro en-aut-sei=Nishida en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NasuYoshihisa en-aut-sei=Nasu en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaigaKenta en-aut-sei=Saiga en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakaharaRyuichi en-aut-sei=Nakahara en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HoritaMasahiro en-aut-sei=Horita en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkitaShunji en-aut-sei=Okita en-aut-mei=Shunji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Takahashi Central Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama City Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=lesser toe kn-keyword=lesser toe en-keyword=metatarsophalangeal joint kn-keyword=metatarsophalangeal joint en-keyword=rheumatoid arthritis kn-keyword=rheumatoid arthritis en-keyword=radiographic measurement kn-keyword=radiographic measurement en-keyword=grading system kn-keyword=grading system END start-ver=1.4 cd-journal=joma no-vol=52 cd-vols= no-issue=2 article-no= start-page=294 end-page=305 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021712 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Emphysematous changes and lower levels of plasma irisin are associated with bronchiolitis obliterans syndrome after bilateral living-donor lobar lung transplantation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose
Decreased irisin levels may be associated with the development of emphysema. Similarly, emphysematous changes may develop in patients with chronic lung allograft dysfunction (CLAD) after living-donor lobar lung transplantation (LDLLT). We investigated the severity of emphysematous changes and the relationship between irisin levels and CLAD after bilateral LDLLT and cadaveric lung transplantation (CLT).

Methods
The subjects of this retrospective study were 59 recipients of bilateral LDLLT (n?=?31) or CLT (n?=?28), divided into a non-CLAD group (n?=?41), a LDLLT-CLAD group (n?=?11), and a CLT-CLAD group (n?=?7). We compared the severity of emphysematous changes, the skeletal muscle mass, and the plasma irisin levels among the groups.

Results
The emphysematous changes were significantly more severe in the LDLLT-CLAD and CLT-CLAD groups (p?=?0.046 and 0.036), especially in patients with bronchiolitis obliterans syndrome (BOS), than in the non-CLAD group. Although the skeletal muscle mass was similar in all the groups, the plasma irisin levels were significantly lower in the LDLLT-CLAD group (p?=?0.022), especially in the patients with BOS after LDLLT, than in the non-CLAD group.

Conclusion
Emphysematous changes and lower levels of plasma irisin were associated with CLAD, especially in patients with BOS, after bilateral LDLLT. en-copyright= kn-copyright= en-aut-name=ShiotaniToshio en-aut-sei=Shiotani en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamamotoHaruchika en-aut-sei=Yamamoto en-aut-mei=Haruchika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OtaniShinji en-aut-sei=Otani en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuzawaKen en-aut-sei=Suzawa en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamamotoHiromasa en-aut-sei=Yamamoto en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamaneMasaomi en-aut-sei=Yamane en-aut-mei=Masaomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=chronic lung allograft dysfunction kn-keyword=chronic lung allograft dysfunction en-keyword=emphysema kn-keyword=emphysema en-keyword=irisin kn-keyword=irisin en-keyword=living-donor kn-keyword=living-donor en-keyword=lung transplantation kn-keyword=lung transplantation END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=4 article-no= start-page=1491 end-page=1498 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210705 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Postoperative external tibial rotation is correlated with inferior meniscal healing following pullout repair of a medial meniscus posterior root tear en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: The purpose of this study was to evaluate the influence of tibial rotation on the postoperative healing status of the medial meniscus (MM) following pullout repair of MM posterior root tear (MMPRT).

Methods: Ninety-one patients (68 women and 23 men, mean age: 63.3 } 8.8 years) who had undergone transtibial pullout repair of MMPRT were enrolled in the study. The tibial external rotation angle (ERA) in each patient was measured postoperatively using computed tomography in the extended knee position. The meniscal healing status following transtibial pullout repair was assessed by second-look arthroscopy (mean postoperative period: 12 months) using a previously published scoring system (range 0?10). The association between ERA and meniscal healing score was investigated using univariate linear regression models. The ERA cut-off for improved meniscal healing score (? 7) was determined using receiver-operating characteristic analysis.

Results: The ERA and meniscal healing score were significantly associated, this confirming increased ERAs to be correlated with worse meniscal healing status (R = -0.28; P < 0.001). The optimum ERA cut-off was 0.69?, with a sensitivity of 65% and a specificity of 66%. The mean meniscal healing score was 7.2 among patients with an ERA of < 0.69?, and 6.1 among patients with an ERA of ? 0.69? (P < 0.001).

Conclusion: This study demonstrated that ERA was significantly correlated with postoperative meniscal healing status. Postoperative tibial rotation could be one of the causes affecting postoperative outcomes of pullout repair of MMPRT. Surgeons should consider some protective strategies for the repaired meniscus in patients with large postoperative tibial external rotation. en-copyright= kn-copyright= en-aut-name=HiranakaTakaaki en-aut-sei=Hiranaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KintakaKeisuke en-aut-sei=Kintaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KamatsukiYusuke en-aut-sei=Kamatsuki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ZhangXiming en-aut-sei=Zhang en-aut-mei=Ximing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=XueHaowei en-aut-sei=Xue en-aut-mei=Haowei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Kousei Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Kochi Health Sciences Center kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= en-keyword=Medial meniscus kn-keyword=Medial meniscus en-keyword=Posterior root tear kn-keyword=Posterior root tear en-keyword=Pullout repair kn-keyword=Pullout repair en-keyword=Tibial rotation kn-keyword=Tibial rotation en-keyword=Sensitivity and specificity kn-keyword=Sensitivity and specificity en-keyword=Meniscal healing kn-keyword=Meniscal healing END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=1 article-no= start-page=12298 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210610 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Extracellular vesicle-shuttled miRNAs as a diagnostic and prognostic biomarker and their potential roles in gallbladder cancer patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Circulating microRNAs (miRNAs) in serum extracellular vesicles (EVs) are a promising biomarker in cancer. We aimed to elucidate the serum EVs miRNA biomarkers to identify patients with gallbladder cancer (GBC) and to clarify their potential roles. One hundred nineteen serum EVs from GBC and non-GBC individuals were isolated by pure-EVs-yieldable size-exclusion chromatography, and then were analyzed using a comprehensive miRNAs array and RT-qPCR-based validation. The functional roles of the identified miRNAs were also investigated using GBC cell lines. Serum EVs miR-1246 and miR-451a were significantly upregulated and downregulated, respectively in GBC patients (P=0.005 and P=0.001), in line with their expression levels in cancer tissue according to an in silico analysis. The combination of CEA and CA19-9 with miR-1246 showed the highest diagnostic power (AUC, 0.816; Sensitivity, 72.0%; Specificity, 90.8%), and miR-1246 was an independent prognostic marker of GBC (Hazard ratio, 3.05; P=0.017) according to a Cox proportional hazards model. In vitro, miR-1246 promoted cell proliferation and invasion, while miR-451a inhibited cell proliferation and induced apoptosis with the targeting of MIF, PSMB8 and CDKN2D. Taken together, miR-1246 in serum EVs has potential application as a diagnostic and prognostic marker and miR-451a may be a novel therapeutic target in GBC. en-copyright= kn-copyright= en-aut-name=UetaEijiro en-aut-sei=Ueta en-aut-mei=Eijiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsutsumiKoichiro en-aut-sei=Tsutsumi en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatoHironari en-aut-sei=Kato en-aut-mei=Hironari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsushitaHiroshi en-aut-sei=Matsushita en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShirahaHidenori en-aut-sei=Shiraha en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiiMasakuni en-aut-sei=Fujii en-aut-mei=Masakuni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HoriguchiShigeru en-aut-sei=Horiguchi en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=2 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Internal Medicine, Okayama Saiseikai General Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=1 article-no= start-page=708 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210616 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Preoperative prognostic nutritional index predicts postoperative infectious complications and oncological outcomes after hepatectomy in intrahepatic cholangiocarcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: In the surgical treatment of intrahepatic cholangiocarcinoma (ICC), postoperative complications may be predictive of long-term survival. This study aimed to identify an immune-nutritional index (INI) that can be used for preoperative prediction of complications.
Patients and methods: Multi-institutional data from 316 patients with ICC who had undergone surgical resection were retrospectively analysed, with a focus on various preoperative INIs.
Results: Severe complications (Clavien-Dindo grade III-V) were identified in 66 patients (20.8%), including Grade V complications in 7 patients (2.2%). Comparison of areas under the receiver operating characteristic curve (AUCs) among various INIs identified the prognostic nutritional index (PNI) as offering the highest predictive value for severe complications (AUC = 0.609, cut-off = 50, P = 0.008). Multivariate analysis revealed PNI < 50 (odds ratio [OR] = 2.22, P = 0.013), hilar lesion (OR = 2.46, P = 0.026), and long operation time (OR = 1.003, P = 0.029) as independent risk factors for severe complications. In comparing a high-PNI group (PNI >= 50, n = 142) and a low-PNI group (PNI < 50, n = 174), the low-PNI group showed higher rates of both major complications (27% vs. 13.4%; P = 0.003) and infectious complications (14.9% vs. 3.5%; P = 0.0021). Furthermore, median survival time and 1- and 5-year overall survival rates were 34.2 months and 77.4 and 33.8% in the low-PNI group, respectively, and 52.4 months and 89.3 and 47.5% in the high-PNI group, respectively (P = 0.0017).
Conclusion: Preoperative PNI appears useful as an INI correlating with postoperative severe complications and as a prognostic indicator for ICC. en-copyright= kn-copyright= en-aut-name=MatsudaTatsuo en-aut-sei=Matsuda en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UmedaYuzo en-aut-sei=Umeda en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsudaTadakazu en-aut-sei=Matsuda en-aut-mei=Tadakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EndoYoshikatsu en-aut-sei=Endo en-aut-mei=Yoshikatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SatoDaisuke en-aut-sei=Sato en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KojimaToru en-aut-sei=Kojima en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuiKenta en-aut-sei=Sui en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=InagakiMasaru en-aut-sei=Inagaki en-aut-mei=Masaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OtaTetsuya en-aut-sei=Ota en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HiokiMasayoshi en-aut-sei=Hioki en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OishiMasahiro en-aut-sei=Oishi en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KimuraMasashi en-aut-sei=Kimura en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MurataToshihiro en-aut-sei=Murata en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=IshidoNobuhiro en-aut-sei=Ishido en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=YagiTakahito en-aut-sei=Yagi en-aut-mei=Takahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Surgery, Tenwakai Matsuda Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Surgery, Tenwakai Matsuda Hospital kn-affil= affil-num=4 en-affil=Department of Surgery, Japanese Red Cross Himeji Hospital kn-affil= affil-num=5 en-affil=Department of Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=6 en-affil=Department of Surgery, Okayama Saiseikai General Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=8 en-affil=Department of Surgery, National Hospital Organization Fukuyama Medical Center kn-affil= affil-num=9 en-affil=Department of Surgery, National Hospital Organization Okayama Medical Center kn-affil= affil-num=10 en-affil=Department of Surgery, Fukuyama City Hospital kn-affil= affil-num=11 en-affil=Department of Surgery, Tottori Municipal Hospital kn-affil= affil-num=12 en-affil=Department of Surgery, Matsuyama Shimin Hospital kn-affil= affil-num=13 en-affil=Department of Surgery, Onomichi Municipal Hospital kn-affil= affil-num=14 en-affil=Department of Surgery, Japanese Red Cross Kobe Hospital kn-affil= affil-num=15 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=16 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Intrahepatic cholangiocarcinoma kn-keyword=Intrahepatic cholangiocarcinoma en-keyword=Postoperative complication kn-keyword=Postoperative complication en-keyword=Prognostic nutritional index kn-keyword=Prognostic nutritional index END start-ver=1.4 cd-journal=joma no-vol=164 cd-vols= no-issue=2 article-no= start-page=517 end-page=523 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021619 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mobile endovascular therapy for acute treatment of ruptured vertebral artery dissecting aneurysm in multiple hospitals en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
The patients with ruptured vertebral artery dissecting aneurysm (rVADA) should be treated as early as possible because VADA carries extremely high risk of rebleeding in the acute phase. We have established a mobile endovascular strategy for the patients with rVADA between our flagship center and its affiliated local hospitals. We introduced and reviewed our mobile endovascular therapy in this study.
Methods
We retrospectively evaluated 98 consecutive patients who underwent endovascular surgery for rVADA from 2000 to 2018 at our institution or five affiliated hospitals. When each patient was initially transported to the local affiliated hospitals, neuroendovascular surgeons traveled directly to the affiliated hospital from the flagship center in order to treat the patient there. Clinical outcomes using modified Rankin Scale at 6 months after treatment, radiological results, and procedure-related complications were reviewed to justify our mobile endovascular strategy.
Results
All aneurysms were cured successfully by internal trapping. Favorable outcome was achieved in 61 patients (62.2%) even though 53 patients (54.1%) had presented with severe subarachnoid hemorrhage. Overall mortality rate, treatment-related mortality rate, and treatment related complication rate were 18.4% (18/98), 0%, and 16% (16/98), respectively. There were no differences in clinical and radiological outcomes between the patients treated in the flagship center and those who treated in the affiliated hospitals. Treatment in the affiliated hospital was not a predictive factor of unfavorable outcome in our multivariate analysis, and elderly age (>= 60) was negatively associated with favorable outcome.
Conclusions
Our results prove the efficacy and safety of mobile endovascular therapy for the treatment of rVADA in the ultra-acute stage. Mobile endovascular therapy may work well in the acute treatment of rVADAs in the certain circumstance. en-copyright= kn-copyright= en-aut-name=KidaniNaoya en-aut-sei=Kidani en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugiuKenji en-aut-sei=Sugiu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TerasakaKaoru en-aut-sei=Terasaka en-aut-mei=Kaoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakashimaHiroyuki en-aut-sei=Nakashima en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TokunagaKoji en-aut-sei=Tokunaga en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KobayashiKazuki en-aut-sei=Kobayashi en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KambaraHirokazu en-aut-sei=Kambara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HishikawaTomohito en-aut-sei=Hishikawa en-aut-mei=Tomohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HiramatsuMasafumi en-aut-sei=Hiramatsu en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurosurgery, Kure Kyosai Hospital kn-affil= affil-num=4 en-affil=Department of Neurosurgery, Okayama Kyokuto Hospital kn-affil= affil-num=5 en-affil=Department of Neurosurgery, Okayama City Municipal Hospital kn-affil= affil-num=6 en-affil=Department of Neurosurgery, Tsuyama Chuo Hospital kn-affil= affil-num=7 en-affil=Department of Neurosurgery, Japanese Red Cross Okayama Hospital kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=3 article-no= start-page=397 end-page=402 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202106 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Case of Metastatic Fumarate Hydratase-Deficient?like Renal Cell Carcinoma Successfully Managed by Ipilimumab plus Nivolumab en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a 62-year-old male with metastatic fumarate hydratase-deficient renal cell carcinoma (FH-deficient RCC) without fumarate hydratase (FH) mutation (FH-deficient?like RCC). The International Metastatic RCC Database Consortium risk score was intermediate, and immunotherapy with nivolumab and ipilimumab (Ipi/ Nivo) was initiated. Four cycles of Ipi/Nivo and 5 cycles of nivolumab resulted in a complete response of the metastases. Hypophysitis occurred as an immune-related adverse event after four cycles of Ipi/Nivo. The prognosis of patients with FH-deficient RCC is generally poor. Few reports of FH-deficient RCC successfully treated with Ipi/Nivo have been published. Ipi/Nivo can be effective for treating FH-deficient RCC. en-copyright= kn-copyright= en-aut-name=SekitoTakanori en-aut-sei=Sekito en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei=

kn-abstract=Recurrent or metastatic head and neck squamous cell carcinoma (R/MHNSCC) has a poor prognosis. Although nivolumab is approved in Japan for treating R/MHNSCC, the response rate is low. Therefore, identifying pretreatment prognostic factors is necessary. This study assessed the utility of the neutrophil-to-lymphocyte ratio (NLR) and Glasgow Prognostic Score (GPS) as biomarkers of response to nivolumab. We retrospectively collected the data of 56 R/MHNSCC patients treated with nivolumab between May 2017 and December 2019. The Kaplan?Meier method and log-rank test were used to estimate overall survival (OS) and progression-free survival (PFS), and multivariate Cox hazard regression analysis was used to identify independent predictors of survival. Patients with a low pretreatment NLR had prolonged OS, and patients with a low pretreatment GPS had increased OS and PFS. A performance score (PS) of 0-1, development of immune-related adverse events, and GPS of 0-1 were significantly associated with OS in multivariate analysis. In summary, baseline pretreatment NLR and GPS are independently associated with OS in R/MHNSCC patients treated with nivolumab. Administration of nivolumab while maintaining the PS reflects a immune status of the host and leads to a good OS. en-copyright= kn-copyright= en-aut-name=ChikuieNobuyuki en-aut-sei=Chikuie en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamamotoTakao en-aut-sei=Hamamoto en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UedaTsutomu en-aut-sei=Ueda en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TaruyaTakayuki en-aut-sei=Taruya en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KonoTakashi en-aut-sei=Kono en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FuruieHiromi en-aut-sei=Furuie en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IshinoTakashi en-aut-sei=Ishino en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakenoSachio en-aut-sei=Takeno en-aut-mei=Sachio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Otorhinolaryngology, Head and Neck Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=2 en-affil=Department of Otorhinolaryngology, Head and Neck Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=3 en-affil=Department of Otorhinolaryngology, Head and Neck Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=4 en-affil=Department of Otorhinolaryngology, Head and Neck Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=5 en-affil=Department of Otorhinolaryngology, Head and Neck Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=6 en-affil=Department of Otorhinolaryngology, Head and Neck Surgery, Kure Medical Center and Chugoku Cancer Center kn-affil= affil-num=7 en-affil=Department of Otorhinolaryngology, Head and Neck Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=8 en-affil=Department of Otorhinolaryngology, Head and Neck Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= en-keyword=neutrophil-to-lymphocyte ratio kn-keyword=neutrophil-to-lymphocyte ratio en-keyword=nivolumab kn-keyword=nivolumab en-keyword=Glasgow Prognostic Score kn-keyword=Glasgow Prognostic Score en-keyword=recurrent or metastatic head and neck squamous cell carcinoma (R/MHNSCC) kn-keyword=recurrent or metastatic head and neck squamous cell carcinoma (R/MHNSCC) END start-ver=1.4 cd-journal=joma no-vol=51 cd-vols= no-issue= article-no= start-page=1978 end-page=1984 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021529 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Accreditation as a qualified surgeon improves surgical outcomes in laparoscopic distal gastrectomy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: The Endoscopic Surgical Skill Quantification System for qualified surgeons (QSs) was introduced in Japan to improve surgical outcomes. This study reviewed the surgical outcomes after initial experience performing laparoscopic distal gastrectomy (LDG) and evaluated the improvement in surgical outcomes following accreditation as a QS.
Methods: Eighty-seven consecutive patients who underwent LDG for gastric cancer by a single surgeon were enrolled in this study. The cumulative sum method was used to analyze the learning curve for LDG. The surgical outcomes were evaluated according to the two phases of the learning curve (learning period vs. mastery period) and accreditation (non-QS period vs. QS period).
Results: The learning period for LDG was 48 cases. Accreditation was approved at the 67th case. The operation time and estimated blood loss were significantly reduced in the QS period compared to the non-QS period (230 vs. 270 min, p<0.001; 20.5 vs. 59.8 ml, p=0.024, respectively). Furthermore, the major complication rate was significantly lower in the QS period than in the non-QS period (0 vs. 10.6%, p=0.044).
Conclusions: Experience performing approximately 50 cases is required to reach proficiency in LDG. After receiving accreditation as a QS, the surgical outcomes, including the complication rate, were improved. en-copyright= kn-copyright= en-aut-name=KikuchiSatoru en-aut-sei=Kikuchi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KagawaTetsuya en-aut-sei=Kagawa en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurodaShinji en-aut-sei=Kuroda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishizakiMasahiko en-aut-sei=Nishizaki en-aut-mei=Masahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakataNobuo en-aut-sei=Takata en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KuwadaKazuya en-aut-sei=Kuwada en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShojiRyohei en-aut-sei=Shoji en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KakiuchiYoshihiko en-aut-sei=Kakiuchi en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=UmedaYuzo en-aut-sei=Umeda en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KagawaShunsuke en-aut-sei=Kagawa en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Shikoku Cancer Center kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Surgery, Okayama Red Cross Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Endoscopic surgical skill quantification system kn-keyword=Endoscopic surgical skill quantification system en-keyword=Qualified surgeon kn-keyword=Qualified surgeon en-keyword=Laparoscopic distal gastrectomy kn-keyword=Laparoscopic distal gastrectomy en-keyword=Gastric cancer kn-keyword=Gastric cancer en-keyword=Cumulative sum analysis kn-keyword=Cumulative sum analysis END start-ver=1.4 cd-journal=joma no-vol=970 cd-vols= no-issue= article-no= start-page=609 end-page=620 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201967 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cross-Cultural Analysis of Top Page Design Among Brazilian, Chinese, Japanese and United States Web Sites en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of present study was to reveal the differences of web design including cultural preference among the four countries that have different cultures.

When the web site had each factor, the researcher gave a "1" for that factor. Chi-square goodness-of-fit test was performed to compare the percentage of "0" or "1" of each factor among the four countries. Additionally, the correspondence analysis was performed to grasp the characteristics of each country. The characteristics of the top page design of the four countries were grasped based on these analyses. en-copyright= kn-copyright= en-aut-name=DoiToshihisa en-aut-sei=Doi en-aut-mei=Toshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= en-keyword=Web design kn-keyword=Web design en-keyword=Cultural difference kn-keyword=Cultural difference en-keyword=Appearance kn-keyword=Appearance en-keyword=Cultural usability kn-keyword=Cultural usability END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=ƒ‰ƒhƒ“‚ƃgƒƒ“‚Ì‹z“ü‚É‚æ‚éƒ}ƒEƒX”‘ŸŠí’†‚ÌRŽ_‰»Œø‰Ê‚ÉŠÖ‚·‚é”äŠrŒ¤‹† kn-title=Comparison of antioxidative effects between radon and thoron inhalation in mouse organs en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KobayashiYusuke en-aut-sei=Kobayashi en-aut-mei=Yusuke kn-aut-name=¬‹´—C‰î kn-aut-sei=¬‹´ kn-aut-mei=—C‰î aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil=‰ªŽR‘åŠw‘åŠw‰@•ÛŒ’ŠwŒ¤‹†‰È END start-ver=1.4 cd-journal=joma no-vol=41 cd-vols= no-issue=5 article-no= start-page=2511 end-page=2521 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20215 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relevance of CYP3A5 Expression on the Clinical Outcome of Patients With Renal Cell Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Aim: This study aimed to elucidate the detailed characteristics of CYP3A5 expression and the association between CYP3A5 expression and clinical outcomes in patients with renal cell carcinoma (RCC). Patients and Methods: This study retrospectively enrolled 124 Japanese patients with RCC treated at the Okayama University Hospital. The commonest CYP3A5 gene polymorphism, CYP3A5*3, and expression levels of CYP3A5 mRNA and protein in each tissue were examined. Results: Expression of CYP3A5 mRNA and protein in RCC tissues was significantly down-regulated compared to that in adjacent normal tissues. High level of CYP3A5 mRNA expression significantly extended cancer-specific survival (p=0.004) and overall survival (p=0.002). The CYP3A5 mRNA expression level was identified as a significant independent prognostic factor for both cancer-specific survival and overall survival. Conclusion: CYP3A5 could serve as a potential marker for prognostication and treatment planning for patients with RCC. en-copyright= kn-copyright= en-aut-name=MatsumotoJun en-aut-sei=Matsumoto en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KoteraYumi en-aut-sei=Kotera en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatariShogo en-aut-sei=Watari en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakeuchiKoichi en-aut-sei=Takeuchi en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UekiHideo en-aut-sei=Ueki en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KoyamaToshihiro en-aut-sei=Koyama en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WadaKoichiro en-aut-sei=Wada en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujiyoshiMasachika en-aut-sei=Fujiyoshi en-aut-mei=Masachika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NasuYasutomo en-aut-sei=Nasu en-aut-mei=Yasutomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AriyoshiNoritaka en-aut-sei=Ariyoshi en-aut-mei=Noritaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Personalized Medicine and Preventive Healthcare Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Personalized Medicine and Preventive Healthcare Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Personalized Medicine and Preventive Healthcare Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Pharmaceuticals Biomedicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Personalized Medicine and Preventive Healthcare Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Personalized Medicine and Preventive Healthcare Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=human kn-keyword=human en-keyword=cytochrome P450 CYP3A kn-keyword=cytochrome P450 CYP3A en-keyword=renal cell carcinoma treatment outcome kn-keyword=renal cell carcinoma treatment outcome END start-ver=1.4 cd-journal=joma no-vol=107 cd-vols= no-issue=2 article-no= start-page=102816 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20214 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Intraarticular lengths of double-bundle grafts can change during knee flexion: Intraoperative measurements in anatomic anterior cruciate ligament reconstructions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The lengths of the anteromedial bundle (AMB) and posterolateral bundle (PLB) change during knee motion during double-bundle anterior cruciate ligament (ACL) reconstruction. However, the actual intraarticular graft length would be affected by the bone tunnel position and tunnel creation angle during ACL reconstruction. The aim of this study was to investigate the intraarticular length change of the AMB and PLB in patients who underwent anatomic double-bundle ACL reconstruction.

Hypothesis: We hypothesized that the PLB would show a more dynamic length change pattern than the AMB during knee flexion at ACL reconstruction.

Methods: Thirty-two patients (16 men and 16 women) who had isolated ACL injuries with intact menisci were investigated. Anatomic double-bundle ACL reconstructions were performed using semitendinosus tendon autografts at a mean age of 30.6 years. The graft and tunnel lengths were measured intraoperatively. Intraarticular graft lengths and length changes were calculated at 0? and 90? of knee flexion during ACL reconstruction. Intraoperative data were collected prospectively, and analyses were performed retrospectively.

Results: The intraarticular length of the AMB at 0? of knee flexion was 28.1 } 5.5 mm. At 90? of knee flexion, the AMB intraarticular length decreased to 25.6 } 4.8 mm. The intraarticular length of the PLB decreased to 17.7 } 4.6 mm at 90? of knee flexion compared to 22.0 } 4.2 mm at 0? of knee flexion. Changes in the intraarticular graft length during knee flexion were detected more in the PLB (4.1 mm) than in the AMB (2.0 mm, P = 0.01).

Discussion: This study demonstrated that the intraarticular length change of the PLB during knee motion was larger than that of the AMB in anatomic double-bundle ACL reconstructions with semitendinosus tendon autografts and suspensory femoral fixation devices. en-copyright= kn-copyright= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiranakaTakaaki en-aut-sei=Hiranaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KodamaYuya en-aut-sei=Kodama en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KamatsukiYusuke en-aut-sei=Kamatsuki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamawakiTadashi en-aut-sei=Yamawaki en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=EndoHirosuke en-aut-sei=Endo en-aut-mei=Hirosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= en-keyword=Anterior cruciate ligament kn-keyword=Anterior cruciate ligament en-keyword=Anatomic double-bundle reconstruction kn-keyword=Anatomic double-bundle reconstruction en-keyword=Intraarticular length kn-keyword=Intraarticular length en-keyword=Semitendinosus autograft kn-keyword=Semitendinosus autograft END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=2 article-no= start-page=147 end-page=152 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Knee Flexion-induced Translation of Pullout Sutures Used in the Repair of Medial Meniscus Posterior Root Tears en-subtitle= kn-subtitle= en-abstract= kn-abstract=Medial meniscus posterior root tears (MMPRTs) have recently attracted considerable interest in orthopedics. To date, no in vivo human study has investigated suture translation changes in repaired MMPRTs with different degrees of knee flexion. This study examined suture translation at various degrees of knee flexion in 30 patients undergoing medial meniscus posterior root repair using the modified Mason-Allen suture technique between August 2016 and September 2017. Intraoperatively, sutures were provisionally fixed to an isometric positioner at the tibial site of the desired meniscal attachment, and the suture translation was measured at 0‹, 30‹, 60‹, and 90‹ of knee flexion. The results showed significant increases in mean suture translation at the knee flexion positions from 0‹ to 30‹, 30‹ to 60‹, and 60‹ to 90‹ (p<0.01 for all). Our findings indicate that surgeons should carefully assess the degree of knee flexion at the moment when the meniscus is refixed by surgical sutures. en-copyright= kn-copyright= en-aut-name=XueHaowei en-aut-sei=Xue en-aut-mei=Haowei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiranakaTakaaki en-aut-sei=Hiranaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KintakaKeisuke en-aut-sei=Kintaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiiMasataka en-aut-sei=Fujii en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ZhangXiming en-aut-sei=Zhang en-aut-mei=Ximing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=medial meniscus kn-keyword=medial meniscus en-keyword=posterior root tear kn-keyword=posterior root tear en-keyword=suture translation kn-keyword=suture translation en-keyword=knee flexion kn-keyword=knee flexion en-keyword=arthroscopic repair kn-keyword=arthroscopic repair END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=2 article-no= start-page=125 end-page=131 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bone Histomorphometry of Femoral Head Cancellous Bone in Patients Who Underwent Total Hip Arthroplasties due to Destructive Hip in Rheumatoid Arthritis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rheumatoid arthritis (RA) affects the hip joints. The microarchitecture of the cancellous bone in RA-affected hip joints has been unclear. Here we investigated the bone metabolism changes in the subcapital cancellous bone of destructive hips of RA patients (n=26 patients; 28 hip joints) which were classified by Larsen grade on X-ray into the groups: destructive hip (Des) (Larsen grade IV, n=18) and neck fracture (Fx) (Larsen grade 0 or 1, n=10). The femoral heads of the Des-group showed significantly higher trabecular thickness versus those of the Fx-group (179}30.8 vs. 151}23.5 ƒÊm, p=0.02). The Des-group had significantly higher osteoid volume/tissue volume (OV/TV) and osteoid volume/bone volume (OV/BV) ratios than the Fx-group (OV/TV: 0.72}0.70% vs. 0.27}0.32%, p=0.028; OV/BV: 2.96}2.85% vs. 1.24}1.31%, p=0.039). The osteoblast and osteoclast surface areas of the Des-group were remarkably higher than those of the Fx-group (9.80}10.9 vs. 0.15}0.15%, p=0.0005; 0.34}0.48 vs. 0.06}0.06%, p=0.0285, respectively). The T-scores of hip (femoral neck) bone mineral density (BMD) of the Fx-group were significantly lower versus those of the Des-group (?3.1}0.76 vs. ?1.6}1.17, p<0.01). Increased osteoid and resorption parameters and higher femoral neck BMD demonstrate a high bone-turnover state in response to destructive changes in the hips of RA patients. en-copyright= kn-copyright= en-aut-name=KijimaYasufumi en-aut-sei=Kijima en-aut-mei=Yasufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KondoNaoki en-aut-sei=Kondo en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkumuraGo en-aut-sei=Okumura en-aut-mei=Go kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EndoNaoto en-aut-sei=Endo en-aut-mei=Naoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=2 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=3 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=4 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= en-keyword=bone histomorphometry kn-keyword=bone histomorphometry en-keyword=rheumatoid arthritis kn-keyword=rheumatoid arthritis en-keyword=destructive hip kn-keyword=destructive hip en-keyword=femoral neck fracture kn-keyword=femoral neck fracture en-keyword=bone turnover kn-keyword=bone turnover END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association of glucocorticoid doses and emotional health in lupus low disease activity state (LLDAS): a cross-sectional study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background While survival of systemic lupus erythematosus (SLE) patients has improved substantially, problems remain in the management of their emotional health. Medium to high-dose glucocorticoid doses are known to worsen emotional health; the effect is unclear among patients receiving relatively low-dose glucocorticoids. This study aims to investigate the association between low glucocorticoid doses and emotional health in lupus low disease activity state (LLDAS). Methods This cross-sectional study drew on data from SLE patients in 10 Japanese institutions. The participants were adult patients with SLE duration of >= 1 year who met LLDAS criteria at the study visit from April 2018 through September 2019. The exposure was the daily glucocorticoid dose (mg oral prednisolone). The outcome was the emotional health score of the lupus patient-reported outcome scale (range: 0 to 100). Multiple linear regression analysis was performed with adjustment for confounders including disease-related damage, activity, and psychotropic drug use. Results Of 192 patients enrolled, 175 were included in the analysis. Their characteristics were as follows: female, 89.7%; median age, 47 years (interquartile range (IQR): 37.0, 61.0). Median glucocorticoid dose was 4.0 mg (IQR 2.0, 5.0), and median emotional health score 79.2 (IQR 58.3, 91.7). Multiple linear regression analysis showed daily glucocorticoid doses to be associated with worse emotional health (beta coefficient = - 2.54 [95% confidence interval - 4.48 to - 0.60], P = 0.01). Conclusions Daily glucocorticoid doses were inversely associated with emotional health among SLE patients in LLDAS. Further studies are needed to determine whether glucocorticoid tapering leads to clinically significant improvements in emotional health. en-copyright= kn-copyright= en-aut-name=MiyawakiYoshia

kn-title=Experimental variable effects on laser heating of inclusions during Raman spectroscopic analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract= Raman spectroscopy for fluid, melt, and mineral inclusions provides direct insight into the physicochemical conditions of the environment surrounding the host mineral at the time of trapping. However, the obtained Raman spectral characteristics such as peak position are modified because of local temperature enhancement of the inclusions by the excitation laser, which might engender systematic errors and incorrect conclusions if the effect is not corrected. Despite the potentially non-negligible effects of laser heating, the laser heating coefficient (B) (‹C/mW) of inclusions has remained unsolved. For this study, we found B from experiments and heat transport simulation to evaluate how various parameters such as experimental conditions, mineral properties, and inclusion geometry affect B of inclusions. To assess the parameters influencing laser heating, we measured B of a total of 19 CO2-rich fluid inclusions hosted in olivine, orthopyroxene, clinopyroxene, spinel, and quartz. Our results revealed that the measured B of fluid inclusions in spinel is highest (approx. 6?‹C/mW) and that of quartz is lowest (approx. 1?~?10?2?‹C/mW), consistent with earlier inferences. Our simulation results show that the absorption coefficient of the host mineral is correlated linearly with B. It is the most influential parameter when the absorption coefficient of the host mineral (ƒ¿h) is larger than that of an inclusion (ƒ¿inc). Furthermore, although our results indicate that both the inclusion size and depth have little effect on B if ƒ¿h?>?ƒ¿inc, the thickness and radius of the host mineral slightly influence B. These results suggest that the choice of inclusion size and depth to be analyzed in a given sample do not cause any systematic error in the Raman data because of laser heating, but the host radius and thickness, which can be adjusted to some degree at the time of sample preparation, can cause systematic errors between samples.Our results demonstrate that, even with laser power of 10?mW, which is typical for inclusion analysis, the inclusion temperature rises to tens or hundreds of degrees during the analysis, depending especially on the host mineral geometry and optical properties. Therefore, correction of the heating effects will be necessary to obtain reliable data from Raman spectroscopic analysis of inclusions. This paper presents some correction methods for non-negligible effects of laser heating. en-copyright= kn-copyright= en-aut-name=HagiwaraYuuki en-aut-sei=Hagiwara en-aut-mei=Yuuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshidaKenta en-aut-sei=Yoshida en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YonedaAkira en-aut-sei=Yoneda en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TorimotoJunji en-aut-sei=Torimoto en-aut-mei=Junji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoJunji en-aut-sei=Yamamoto en-aut-mei=Junji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Science, Hokkaido University kn-affil= affil-num=2 en-affil=Research Institute for Marine Geodynamics, Japan Agency for Marine-Earth Science and Technology (JAMSTEC) kn-affil= affil-num=3 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=4 en-affil=Ore Genesis Research Unit, Project Team for Development of New-Generation Research Protocol for Submarine Resources, Japan Agency for Marine-Earth Science and Technology (JAMSTEC) kn-affil= affil-num=5 en-affil=The Hokkaido University Museum kn-affil= en-keyword=Finite element method kn-keyword=Finite element method en-keyword=Inclusions kn-keyword=Inclusions en-keyword=Laser heating kn-keyword=Laser heating en-keyword=Raman spectroscopy kn-keyword=Raman spectroscopy END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210107 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prevention and early management of carotid blowout syndrome for patients receiving head and neck salvage boron neutron capture therapy (BNCT) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/purpose
The incidence rate of oral and pharyngeal cancers in Taiwan has increased gradually over the past few decades. The standard treatment strategy for oral and pharyngeal cancers includes surgery or radiotherapy, with concurrent chemotherapy in certain types of tumors. Unfortunately, in-field recurrence is sometimes inexorable. Furthermore, re-irradiation of the recurrence site may cause severe complications due to the tolerance of normal tissue to radiation therapy. One fatal complication is carotid blowout syndrome (CBS). Boron neutron capture therapy (BNCT) is a new modality of radiation therapy, which is also mentioned as targeted radiotherapy. It is a feasible treatment that has the potential to spare normal tissue from being damaged by irradiation while simultaneously treating the primary tumor. In this presentation, we will share our experience with BNCT in treating recurrent head and neck cancers, as well as the prevention and management of CBS.
Materials and methods
We evaluated 4 patients with head and neck cancers treated by BNCT in Taiwan. All patients had undergone surgery previously and had received postoperative concurrent chemoradiotherapy.
Results
The 4 patients in this study were diagnosed with head and neck malignancies. The median follow-up period after the first course of BNCT was 15.1 months. After BNCT, 2 patients developed impending CBS, and 1 of them died. The remaining 3 patients survived until the last date of follow-up.
Conclusion
Pre-BNCT carotid artery evaluation through computed tomography angiography and early intervention if necessary is crucial when treating patients with recurrent head and neck cancers by BNCT. en-copyright= kn-copyright= en-aut-name=LanTien-Li en-aut-sei=Lan en-aut-mei=Tien-Li kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ChangFeng-Chi en-aut-sei=Chang en-aut-mei=Feng-Chi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WangChun-Wei en-aut-sei=Wang en-aut-mei=Chun-Wei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IgawaKazuyo en-aut-sei=Igawa en-aut-mei=Kazuyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WuSzu-Hsien en-aut-sei=Wu en-aut-mei=Szu-Hsien kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=LoWen-Liang en-aut-sei=Lo en-aut-mei=Wen-Liang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ChenYi-Wei en-aut-sei=Chen en-aut-mei=Yi-Wei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Division of Radiotherapy, Department of Oncology, Taipei Veterans General Hospital kn-affil= affil-num=2 en-affil=Department of Radiology, Taipei Veterans General Hospital kn-affil= affil-num=3 en-affil=Division of Radiotherapy, Department of Oncology, Taiwan University Hospital kn-affil= affil-num=4 en-affil=Neutron Therapy Research Center, Okayama University kn-affil= affil-num=5 en-affil=Division of Plastic and Reconstructive Surgery, Taipei Veterans General Hospital kn-affil= affil-num=6 en-affil=Division of Oral and Maxillofacial Surgery, Department of Stomatology, Taipei Veterans General Hospital kn-affil= affil-num=7 en-affil=Division of Radiotherapy, Department of Oncology, Taipei Veterans General Hospital kn-affil= en-keyword=Boron neutron capture therapy kn-keyword=Boron neutron capture therapy en-keyword=Carotid blowout syndrome kn-keyword=Carotid blowout syndrome en-keyword=Head and neck cancerQuality of life kn-keyword=Head and neck cancerQuality of life en-keyword=Recurrence kn-keyword=Recurrence END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210121 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Profile of down syndrome?associated malignancies: Epidemiology, clinical features and therapeutic aspects en-subtitle= kn-subtitle= en-abstract= kn-abstract=Down syndrome (DS) is a congenital chromosomal abnormality caused by the presence of all or part of a third copy of chromosome 21 (+21). DS is frequently complicated by congenital heart or digestive tract diseases at birth. DS patients are prone to infections and have mental retardation, with dementia such as Alzheimer's disease showing in later life. Furthermore, malignancies with specific characteristics are also highly reported in DS patients compared with non-DS patients. Therefore, DS is believed to be a cancer predisposition syndrome due to the chromosomal instability. Acute myeloid leukemia (AML) and especially acute megakaryoblastic leukemia (AMKL) by French-American-British (FAB) classification are the most frequent hematological malignancies in DS patients, occurring at a rate that is 500 times higher than that in non-DS patients. Interestingly, transient abnormal myelopoiesis (TAM) is observed in approximately 10% of DS neonates with GATA1 mutations, and most TAM patients are asymptomatic and show spontaneous regression; however, about 10%?20% of TAM cases are fatal because of complications such as fetal effusion, liver fibrosis, and other complications.Acute lymphoblastic leukemia (ALL) is also associated with DS, occurring at a rate that is 20 times higher than that in non-DS patients. Furthermore, the prognosis of DS-ALL patients is poorer than that of non-DS-ALL patients. A recent genetic analysis revealed that more than half of DS-ALL cases have a mutation in the CRLF2?JAK pathway, indicating that JAK inhibitors might have a limited effect for DS-ALL patients.Notably, solid tumors such as neuroblastoma, Wilms tumor, and brain tumor, which are frequently observed in non-DS children, are rarely reported in DS children. The reason remains unknown, but it may be because of the triplication of the Down syndrome critical region 1 (DSCR1) gene on chromosome 21. In adult patients with DS, the expected age-adjusted incidence rates of solid tumors are low compared with age-matched euploid cohorts for most cancers except for testicular cancer. Although the average life expectancy of patients with DS will increase with advances in healthcare, the detailed health problems including cancer rates in older DS patients remain unknown. Therefore, these issues will be needed to be addressed in future studies. en-copyright= kn-copyright= en-aut-name=ShimadaAkira en-aut-sei=Shimada en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Pediatric Hematology, Okayama University Hospital kn-affil= en-keyword=Down syndrome kn-keyword=Down syndrome en-keyword=Acute myeloid leukemia kn-keyword=Acute myeloid leukemia en-keyword=Acute megakaryoblastic leukemia kn-keyword=Acute megakaryoblastic leukemia en-keyword=Transient abnormal myelopoiesis kn-keyword=Transient abnormal myelopoiesis en-keyword=Acute lymphoblastic leukemia kn-keyword=Acute lymphoblastic leukemia en-keyword=Solid tumor kn-keyword=Solid tumor en-keyword=Cancer predisposition syndrome kn-keyword=Cancer predisposition syndrome en-keyword=GATA1 kn-keyword=GATA1 en-keyword=Down syndrome critical region 1 kn-keyword=Down syndrome critical region 1 END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=380 end-page=388 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210131 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A comparison of colorimetric and visual methods for the assessment of masticatory performance with color-changeable chewing gum in older persons en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/purpose
Color-changeable chewing gum is used for the evaluation of masticatory performance. However, it is currently unclear whether colorimetric and visual assessment methods yield consistent results. This study aimed to clarify the consistency between colorimetric and visual methods used for the evaluation of color changes in color-changeable chewing gum.
Materials and methods
The sample comprised 644 older persons (mean age, 75.4?}?6.4 years). The chewing gum was masticated 60 times at the participant's own chewing rate and then expectorated. The color of the chewing gum was evaluated with the ƒ¢E values and a? values, measured using a colorimeter, and the 10 Color Shades (10CSh) and 5 Color Scales (5CSc), using visual evaluation. Spearman's correlation analysis was performed to examine the correlation between the results obtained by the four methods. The significance level was set at ƒ¿?=?0.05.
Results
The ĢE values, a? values, 10CSh scores, and 5CSc scores were all significantly correlated. The highest correlation coefficient (0.979) was between the ĢE values and a? values. The lowest correlation coefficient (0.847) was between the a? values and 5CSc scores. Decreased masticatory performance was observed with increased age.
Conclusion
Significant correlations were found for all four methods used in the assessment of masticatory performance with color-changeable chewing gum. While visually based assessments are valid, colorimetric methods are more sensitive to smaller changes in masticatory performance. en-copyright= kn-copyright= en-aut-name=KugimiyaYoshihiro

EGFR Mutations en-subtitle= kn-subtitle= en-abstract= kn-abstract=Patients with NSCLC in East Asia, including Japan, frequently contain EGFR mutations. In 2018, we published the latest full clinical practice guidelines on the basis of those provided by the Japanese Lung Cancer Society Guidelines Committee. The purpose of this study was to update those recommendations, especially for the treatment of metastatic or recurrent EGFR-mutated NSCLC. We conducted a literature search of systematic reviews of randomized controlled and nonrandomized trials published between 2018 and 2019 that multiple physicians had reviewed independently. On the basis of those studies and the advice from the Japanese Society of Lung Cancer Expert Panel, we developed updated guidelines according to the Grading of Recommendations, Assessment, Development, and Evaluation system. We also evaluated the benefits of overall and progression-free survival, end points, toxicities, and patientsf reported outcomes. For patients with NSCLC harboring EGFR-activating mutations, the use of EGFR tyrosine kinase inhibitors (EGFR TKIs), especially osimertinib, had the best recommendation as to first-line treatment. We also recommended the combination of EGFR TKI with other agents (platinum-based chemotherapy or antiangiogenic agents); however, it can lead to toxicity. In the presence of EGFR uncommon mutations, except for an exon 20 insertion, we also recommended the EGFR TKI treatment. However, we could not provide recommendations for the treatment of EGFR mutations with immune checkpoint inhibitors, including monotherapy, and its combination with cytotoxic chemotherapy, because of the?limited evidence present in the literature. The 2020 Japanese Lung Cancer Society Guidelines can help community-based physicians to determine the most appropriate treatments and adequately provide medical care to their patients. en-copyright=

kn-subtitle= en-abstract= kn-abstract=Swarming and mating behaviors of a mayfly species, Ephemera orientalis Mclachlan, 1875 were observed in 2015, 2016, and 2018 at a river bank of the Asahi River, Japan. Males started to make swarms between late April and middle May in 2016 and 2018. The numbers of mated pairs in a swarm correlated with the numbers of flying males in a swarm in 2016 and 2018. Swarms were formed during a limited period at dusk most probably because that interval is free from natural enemies. Males competed with each other to copulate with females in swarms. We clarified the function of the forelegs of males, which are significantly longer than those of females. Males used their forelegs to hold up a female from below. Besides forelegs, males have longer tails than females. We will discuss why sexual differences are found in these traits. Our results represent the first observation of swarm mating behavior in E. orientalis. en-copyright= kn-copyright= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugeTaichi en-aut-sei=Suge en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SuzakiShunsuke en-aut-sei=Suzaki en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanabeShintaro en-aut-sei=Tanabe en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshiharaRyo en-aut-sei=Ishihara en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsumuraKentarou en-aut-sei=Matsumura en-aut-mei=Kentarou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Aquatic insect kn-keyword=Aquatic insect en-keyword=Emergence kn-keyword=Emergence en-keyword=Copulation kn-keyword=Copulation en-keyword=Foreleg kn-keyword=Foreleg en-keyword=Mayfly kn-keyword=Mayfly en-keyword=Swarm kn-keyword=Swarm END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=17 end-page=23 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210207 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy of shear wave elastography for evaluating right ventricular myocardial fibrosis in monocrotaline-induced pulmonary hypertension rats en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Right ventricular (RV) function is important for outcomes in pulmonary hypertension. Evaluation of RV myocardial characteristics is useful to assess the disease severity. Shear wave elastography (SWE) provides information of shear wave (SW) elasticity, which is related to tissue hardness, and SW dispersion slope, which reflects tissue viscosity. This study aimed to test the hypothesis that SW elasticity is increased and SW dispersion slope is decreased in the right ventricle of monocrotaline (MCT)-induced pulmonary hypertension rats.

Methods: Rats were divided into MCT-induced pulmonary hypertension group (n = 10) and control group (n = 10). SW elasticity and SW dispersion slope were measured on excised hearts. Myocardial fibrosis was evaluated histologically.

Results: RV hypertrophy was observed in the MCT group. SW elasticity of right ventricle was higher in the MCT group than in the control group (3.5 } 0.9 kPa vs. 2.5 } 0.4 kPa, p < 0.01). SW dispersion slope of right ventricle was lower in the MCT group than in the control group (5.3 } 1.7 m/s/kHz vs. 7.7 } 1.5 m/s/kHz, p < 0.01). The fibrosis area of right ventricle was increased in MCT group compared with control group (18 } 5% vs. 8 } 3%, p < 0.01), and was positively related to SW elasticity and negatively related to SW dispersion slope.

Conclusions: Higher SW elasticity and lower SW dispersion slope were observed in the fibrotic myocardium of right ventricle in MCT-induced pulmonary hypertension rats. SWE may have the potential to evaluate RV function by assessing myocardial characteristics. en-copyright= kn-copyright= en-aut-name=NakayamaRie en-aut-sei=Nakayama en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakayaYoichi en-aut-sei=Takaya en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KondoMegumi en-aut-sei=Kondo en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobayashiKaoru en-aut-sei=Kobayashi en-aut-mei=Kaoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhnoYuko en-aut-sei=Ohno en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AmiokaNaofumi en-aut-sei=Amioka en-aut-mei=Naofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AkagiSatoshi en-aut-sei=Akagi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YoshidaMasashi en-aut-sei=Yoshida en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Kawasaki University of Medical Welfare kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil= Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Dispersion kn-keyword=Dispersion en-keyword=Elasticity kn-keyword=Elasticity en-keyword=Myocardium kn-keyword=Myocardium en-keyword=Right ventricular function kn-keyword=Right ventricular function en-keyword=Shear wave elastography kn-keyword=Shear wave elastography END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=1 article-no= start-page=181 end-page=189 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Medial meniscus posterior root repairs: A comparison among three surgical techniques in short-term clinical outcomes and arthroscopic meniscal healing scores en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Medial meniscus (MM) posterior root repairs lead to favorable clinical outcomes in patients with MM posterior root tears (MMPRTs). However, there are few comparative studies in evaluating the superiority among several pullout repair techniques such as modified Mason?Allen suture, simple stitch, and concomitant posteromedial pullout repair. We hypothesized that an additional pullout suture at the MM posteromedial part would have clinical advantages in transtibial pullout repairs of the MMPRTs. The aim of this study was to compare the clinical usefulness among several types of pullout repair techniques in patients with MMPRTs.
Methods
Eighty-three patients who underwent arthroscopic pullout repairs of the MMPRTs were investigated. Patients were divided into three groups using different pullout repair techniques: a modified Mason?Allen suture using FasT-Fix all-inside meniscal repair device (F-MMA, n?=?28), two simple stitches (TSS, n?=?30), and TSS concomitant with posteromedial pullout repair using all-inside meniscal repair device (TSS-PM, n?=?25). Postoperative clinical outcomes and semi-quantitative arthroscopic meniscal healing scores (0?10 points) were evaluated at second-look arthroscopies.
Results
No significant differences among the three groups were observed in patient demographics and preoperative clinical scores, except for preoperative Lysholm scores. At second-look arthroscopies, there were no significant differences among the three techniques in postoperative clinical outcomes and meniscal healing scores.
Conclusions
This study demonstrated that the TSS-PM pullout repair technique did not show better scores in postoperative clinical outcomes and meniscal healings compared with the F-MMA and TSS techniques. Our results suggest that the concomitant posteromedial pullout suture may have no clinical advantage in the conventional pullout repairs for the patients with MMPRTs. en-copyright= kn-copyright= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiranakaTakaaki en-aut-sei=Hiranaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KintakaKeisuke en-aut-sei=Kintaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KodamaYuya en-aut-sei=Kodama en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KamatsukiYusuke en-aut-sei=Kamatsuki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue= article-no= start-page=100330 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The HMGB1/RAGE axis induces bone pain associated with colonization of 4T1 mouse breast cancer in bone en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bone pain is a common complication of breast cancer (BC) bone metastasis and is a major cause of increased morbidity and mortality. Although the mechanism of BC-associated bone pain (BCABP) remains poorly understood, involvement of BC products in the pathophysiology of BCABP has been proposed. Aggressive cancers secrete damage-associated molecular patterns (DAMPs) that bind to specific DAMP receptors and modulate cancer microenvironment. A prototypic DAMP, high mobility group box 1 (HMGB1), which acts as a ligand for the receptor for advanced glycation end products (RAGE) and toll-like receptors (TLRs), is increased in its expression in BC patients with poor outcomes. Here we show that 4T1 mouse BC cells colonizing bone up-regulate the expression of molecular pain markers, phosphorylated ERK1/2 (pERK) and pCREB, in the dorsal root ganglia (DRGs) innervating bone and induced BCABP as evaluated by hind-paw mechanical hypersensitivity. Importantly, silencing HMGB1 in 4T1 BC cells by shRNA reduced pERK and pCREB and BCABP with decreased HMGB1 levels in bone. Further, administration of a neutralizing antibody to HMGB1 or an antagonist for RAGE, FPS-ZM1, ameliorated pERK, pCREB and BCABP, while a TLR4 antagonist, TAK242, showed no effects. Consistent with these in vivo results, co-cultures of F11 sensory neuron-like cells with 4T1 BC cells in microfluidic culture platforms increased neurite outgrowth of F11 cells, which was blocked by HMGB1 antibody. Our results show that HMGB1 secreted by BC cells induces BCABP via binding to RAGE of sensory neurons and suggest that the HMGB1/RAGE axis may be a potential novel therapeutic target for BCABP. en-copyright= kn-copyright= en-aut-name=OkuiTatsuo en-aut-sei=Okui en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiasaMasahiro en-aut-sei=Hiasa en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=RyumonShoji en-aut-sei=Ryumon en-aut-mei=Shoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OnoKisho en-aut-sei=Ono en-aut-mei=Kisho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KunisadaYuki en-aut-sei=Kunisada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IbaragiSoichiro en-aut-sei=Ibaragi en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SasakiAkira en-aut-sei=Sasaki en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=RoodmanG.

Few studies have investigated the learning curves of minimally invasive donor nephrectomy (MIDN) using the cumulative sum (CUSUM) analysis. In addition, no study has compared the learning curves of the different surgical MIDN techniques in one cohort study using the CUSUM analysis. This study aims to evaluate and compare learning curves for several MIDN using the CUSUM analysis.
Methods
A retrospective review of consecutive donors, who underwent MIDN between 1997 and 2019, was conducted. Three laparoscopic-assisted techniques were applied in our institution and included for analysis: laparoscopic (LDN), hand-assisted retroperitoneoscopic (HARP), and robot-assisted laparoscopic (RADN) donor nephrectomy. The outcomes were compared based on surgeon volume to develop learning curves for the operative time per surgeon.
Results
Out of 1895 MIDN, 1365 (72.0%) were LDN, 427 (22.5%) were HARP, and 103 (5.4%) were RADN. The median operative time and median blood loss were 179 (IQR, 139?230) minutes and 100 (IQR, 40?200) mL, respectively. The incidence of major complication was 1.2% with no mortality, and the median hospital stay was three (IQR, 3?4) days. The CUSUM analysis resulted in learning curves, defined by decreased operative time, of 23 cases in LDN, 45 cases in HARP, and 26 cases in RADN.
Conclusions
Our study shows different learning curves in three MIDN techniques with equal post-operative complications. The LDN and RADN learning curves are shorter than that of the hand-assisted donor nephrectomy. Our observations can be helpful for informing the development of teaching requirements for fellows to be trained in MIDN. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimenaiHendrikus J.A.N. en-aut-sei=Kimenai en-aut-mei=Hendrikus J.A.N. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TerkivatanTurkan en-aut-sei=Terkivatan en-aut-mei=Turkan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TranKhe T.C. en-aut-sei=Tran en-aut-mei=Khe T.C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IjzermansJan N.M. en-aut-sei=Ijzermans en-aut-mei=Jan N.M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MinneeRobert C. en-aut-sei=Minnee en-aut-mei=Robert C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Surgery, Division of HPB & Transplant Surgery, Erasmus MC, University Medical Centre Rotterdam kn-affil= affil-num=3 en-affil=Department of Surgery, Division of HPB & Transplant Surgery, Erasmus MC, University Medical Centre Rotterdam kn-affil= affil-num=4 en-affil=Department of Surgery, Division of HPB & Transplant Surgery, Erasmus MC, University Medical Centre Rotterdam kn-affil= affil-num=5 en-affil=Department of Surgery, Division of HPB & Transplant Surgery, Erasmus MC, University Medical Centre Rotterdam kn-affil= affil-num=6 en-affil=Department of Surgery, Division of HPB & Transplant Surgery, Erasmus MC, University Medical Centre Rotterdam kn-affil= en-keyword=Kidney transplantation kn-keyword=Kidney transplantation en-keyword=Learning curve kn-keyword=Learning curve en-keyword=Hand-assisted laparoscopy kn-keyword=Hand-assisted laparoscopy en-keyword=Laparoscopy kn-keyword=Laparoscopy en-keyword=Living donors kn-keyword=Living donors en-keyword=Nephrectomy kn-keyword=Nephrectomy en-keyword=Teaching kn-keyword=Teaching en-keyword=Robotic surgical procedures kn-keyword=Robotic surgical procedures END start-ver=1.4 cd-journal=joma no-vol=311 cd-vols= no-issue= article-no= start-page=106640 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Thermocapillary effects in two-phase medium and applications to metal-silicate separation en-subtitle= kn-subtitle= en-abstract= kn-abstract= The separation of a liquid phase from a solid but deformable matrix made of mineral grains is controlled at small scale by surface tension. The role of interfacial surface tension is twofold as it explains how a small volume of liquid phase can infiltrate the grain boundaries, be distributed and absorbed in the matrix, but after complete wetting of the grains, surface tension favors the self-separation of the liquid and solid phases. Another consequence of surface tension is the existence of Marangoni forces, which are related to the gradients of surface tension that are are usually due to temperature variations. In this paper, using a continuous multi-phase formalism we clarify the role of these different effects and quantify their importances at the scale of laboratory experiments and in planets. We show that Marangoni forces can control the liquid metal-solid silicate phase separation in laboratory experiments. The Marangoni force might help to maintain the presence of metal at the surface of asteroids and planetesimals that have undergone significant melting. en-copyright= kn-copyright= en-aut-name=RicardYanick en-aut-sei=Ricard en-aut-mei=Yanick kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LabrosseSt?phane en-aut-sei=Labrosse en-aut-mei=St?phane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TerasakiHidenori en-aut-sei=Terasaki en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BercoviciDavid en-aut-sei=Bercovici en-aut-mei=David kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Universit? de Lyon, ENSL, UCBL, Laboratoire LGLTPE kn-affil= affil-num=2 en-affil=Universit? de Lyon, ENSL, UCBL, Laboratoire LGLTPE kn-affil= affil-num=3 en-affil=Okayama University, Department of Earth Sciences kn-affil= affil-num=4 en-affil=Yale University, Department of Earth & Planetary Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=107 cd-vols= no-issue=1 article-no= start-page=124 end-page=125 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reply to the letter by Haitao Chen and Liaobin Chen en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210309 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A case of a middle-aged patient with a ventricular septal defect complicated by severe pulmonary hypertension-stepwise surgical repair with pulmonary vasodilators- en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a case of ventricular septal defect (VSD) in which we attempted to treat pulmonary arterial hypertension (PAH) with the goal of VSD closure in an adult with suspected Eisenmenger syndrome in childhood. Four years previously (age 41 years), she was referred to our department due to repeated hemoptysis requiring further treatment of PAH. We started combination therapy with several pulmonary vasodilators. Two years later, her pulmonary vascular resistance (PVR) was improved but still not at the level where VSD closure was possible. To control the increased PA flow resulting from intensive PAH treatment and to reduce the risk of hemoptysis, we performed pulmonary artery banding (PAB). As the risk of hemoptysis decreased, a prostacyclin analog was introduced, and the dose was increased. More than 1 year after PAB, active vasoactivity testing became positive, suggesting that the pulmonary vascular lesion was now greversibleh. We performed VSD closure and atrial septal defect creation even though her PVR was still high. After the operation, her exercise capacity was remarkably improved. We suggest that stepwise surgical repair with pulmonary vasodilators is an important treatment option for select patients with VSD with severe PAH.Learning objectiveAdvances in pulmonary arterial hypertension (PAH) treatment have led to the use of a gtreat-and-repairh strategy to close the intracardiac shunt after PAH treatment in select patients with adult congenital heart disease. In our case, ventricular septal defect (VSD) closure was achieved with stepwise surgical repair and a combination of pulmonary vasodilators, even though long-standing severe PAH with persistent hemoptysis remained. Even after a long period of exposure to high blood flow, this strategy may reduce pulmonary vascular resistance and permit eventual closure of the VSD. en-copyright= kn-copyright= en-aut-name=KanaiAnna en-aut-sei=Kanai en-aut-mei=Anna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KoitabashiNorimichi en-aut-sei=Koitabashi en-aut-mei=Norimichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AkagiSatoshi en-aut-sei=Akagi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SorimachiHidemi en-aut-sei=Sorimachi en-aut-mei=Hidemi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshibashiYohei en-aut-sei=Ishibashi en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NagasakaTakashi en-aut-sei=Nagasaka en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakamaNoriaki en-aut-sei=Takama en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SomaKatsura en-aut-sei=Soma en-aut-mei=Katsura kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YaoAtsushi en-aut-sei=Yao en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KasaharaShingo en-aut-sei=Kasahara en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KurabayashiMasahiko en-aut-sei=Kurabayashi en-aut-mei=Masahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Gunma University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Gunma University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Gunma University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Gunma University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Gunma University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Gunma University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, The University of Tokyo Hospital kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, The University of Tokyo Hospital kn-affil= affil-num=10 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Cardiovascular Medicine, Gunma University Graduate School of Medicine kn-affil= en-keyword=Pulmonary arterial hypertension kn-keyword=Pulmonary arterial hypertension en-keyword=Ventricular septal defect kn-keyword=Ventricular septal defect en-keyword=Treat-and-repair strategy kn-keyword=Treat-and-repair strategy END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210321 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Intravesical Therapy in Patients with Intermediate-risk Non?muscle-invasive Bladder Cancer: A Systematic Review and Network Meta-analysis of Disease Recurrence en-subtitle= kn-subtitle= en-abstract= kn-abstract=Context
Patients with intermediate-risk non?muscle-invasive bladder cancer (NMIBC) may pose a clinical dilemma without an agreed evidence-based decision tree for personalized treatment.
Objective
To perform a systematic review and network meta-analysis (NMA) to summarize available evidence on the oncologic outcomes of intravesical therapy in patients with intermediate-risk NMIBC.
Evidence acquisition
The MEDLINE, EMBASE, and ClinicalTrials.gov databases were searched in October 2020 according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. Studies were deemed eligible if they reported on oncologic outcomes in patients with intermediate-risk NMIBC treated with transurethral resection of bladder tumor with and without intravesical chemotherapy or bacillus Calmette-Gu?rin (BCG) immunotherapy.
Evidence synthesis
Twelve studies were included in a qualitative synthesis (systematic review); three were deemed eligible for a quantitative synthesis (NMA). An NMA of five different regimens was conducted for the association of treatment with the 5-yr recurrence risk. Chemotherapy with maintenance was associated with a lower likelihood of 5-yr recurrence than chemotherapy without maintenance (odds ratio [OR] 0.51, 95% credible interval [CI] 0.26?1.03). Immunotherapy, regardless of whether a full- or reduced-dose regimen, was not associated with a significantly lower likelihood of 5-yr recurrence when compared with chemotherapy without maintenance (OR 0.90, 95% CI 0.39?2.11 vs OR 0.93, 95% CI 0.40?2.19). Analysis of the treatment ranking revealed that chemotherapy with maintenance had the lowest 5-yr recurrence risk (P score 0.9666).
Conclusions
Our analysis indicates that chemotherapy with a maintenance regimen confers a superior oncologic benefit in terms of 5-yr recurrence risk compared to chemotherapy without maintenance in patients with intermediate-risk NMIBC. Regardless of the dose regimen, immunotherapy with BCG does not appear to be superior to chemotherapy in patients with intermediate-risk NMIBC in term of disease recurrence. However, owing to the lack of comparative studies, there is an unmet need for well-designed, large-scale trials to validate our findings and generate robust evidence on disease recurrence and progression.
Patient summary
A maintenance schedule of chemotherapy reduces the rate of long-term recurrence of bladder cancer that has not invaded the bladder muscle. Chemotherapy inserted directly into the bladder and immunotherapy without maintenance schedules seem to have limited benefit in preventing cancer recurrence. en-copyright= kn-copyright=

for Optimizing Clinical and Functional Outcomes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
This study evaluated the impact of a staged surgical strategy incorporating a modified Blalock-Taussig shunt (BTS) for tetralogy of Fallot (TOF) on pulmonary valve annulus (PVA) growth, the rate of valve-sparing repair (VSR) at the time of intracardiac repair (ICR), and long-term functional outcomes.
Methods
This retrospective study included 330 patients with TOF who underwent ICR between 1991 and 2019, including 57 patients (17%) who underwent BTS. The mean follow-up period was 15.0}7.3 years. We compared the data of patients who underwent BTS and those who did not undergo BTS before ICR.
Results
The median age and body weight before BTS were 71 (28?199) days and 4.3 (3.3?6.8) kg respectively. There were no in-hospital or interstage deaths after BTS. The PVA Z-scores of patients with BTS revealed significant growth after BTS (from -4.2}1.8 to -3.0}1.7, P<0.001). VSR was eventually performed in 207 (63%) patients, including 26 (46%) patients who underwent staged repair. The overall freedom from pulmonary regurgitation-related reintervention were 99.7%, 99.1%, and 95.8% at 1, 5, and 20 years, respectively.
Conclusions
A staged surgical strategy incorporating BTS as the first palliation for symptomatic patients resulted in no mortality. BTS may have contributed to the avoidance of primary transannular patch repair (TAP) and facilitated PVA growth; therefore, approximately half of the symptomatic neonates and infants were recruited for VSR. Staged repair may have led to functionally-reliable delayed TAP repair, thereby resulting in less surgical reinterventions. en-copyright= kn-copyright= en-aut-name=KobayashiYasuyuki en-aut-sei=Kobayashi en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KotaniYasuhiro en-aut-sei=Kotani en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurokoYosuke en-aut-sei=Kuroko en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawabataTakuya en-aut-sei=Kawabata en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SanoShunji en-aut-sei=Sano en-aut-mei=Shunji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KasaharaShingo en-aut-sei=Kasahara en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=2 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=3 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science, kn-affil= affil-num=4 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=5 en-affil=Division of Pediatric Cardiothoracic Surgery, University of California San Francisco kn-affil= affil-num=6 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= en-keyword=dual SAI screws kn-keyword=dual SAI screws en-keyword=adult spine deformity kn-keyword=adult spine deformity en-keyword=spinopelvic fixation kn-keyword=spinopelvic fixation en-keyword=navigation surgery kn-keyword=navigation surgery END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=3 article-no= start-page=102993 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=New metal complexes derived from diacetylmonoxime-n(4)antipyrinylthiosemicarbazone: Synthesis, characterization and evaluation of antitumor activity against Ehrlich solid tumors induced in mice en-subtitle= kn-subtitle= en-abstract= kn-abstract= The present study aimed to synthesize new metal complexes of diacetylmonoxime-N(4)antipyrinylthiosemicarbazone ligand and evaluate their antitumor activity. New complexes with ferric, cobalt, nickel and copper ions were prepared. Elemental, 1H Nuclear magnetic resonance, Mass spectroscopy, Electron paramagnetic resonance, Fourier Transform InfraredSpectroscopy, Ultraviolet?visible and thermal gravimetricanalysis were used to characterize the obtained complexes 1?11. An in vivo tumor model was established to investigate the effect of the naked ligand and its metal complexes 2, 5 and 8. Ehrlich ascites carcinoma solid tumor was induced in mice through subcutaneous inoculation of Ehrlich ascites carcinoma cells. The volumes of the formed solid tumors, the alanine transaminase, aspartate transaminase, albumin concentration in the serum, as well as the levels of Ki67 and p53 proteins in tumor and liver tissues were detected. All the tested complexes, especially complex 5, possessed proliferative inhibition manifested as the reduction of the tumor volume, Alanine aminotransferase & Aspartate aminotransferase activity, and the level of the Ki67 protein. Additionally, they restored the albumin concentration to normal levels as well increased the level of pro-apoptotic p53 protein. In conclusion, the antitumor activity of the newly synthesized metal complexes against Ehrlich ascites carcinoma solid tumors was proved to be mediated by the inhibition of Ki67 and induction of p53 proteins. en-copyright= kn-copyright= en-aut-name=El-AaragBishoy en-aut-sei=El-Aarag en-aut-mei=Bishoy kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=El-SaiedFathy en-aut-sei=El-Saied en-aut-mei=Fathy kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SalemTarek en-aut-sei=Salem en-aut-mei=Tarek kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KhedrNesrin en-aut-sei=Khedr en-aut-mei=Nesrin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KhalifaShaden A.M. en-aut-sei=Khalifa en-aut-mei=Shaden A.M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=El-SeediHesham R. en-aut-sei=El-Seedi en-aut-mei=Hesham R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Division of Chemistry and Biotechnology, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Faculty of Science, Menoufia University kn-affil= affil-num=3 en-affil=Department of Biochemistry, College of Medicine, Qassim University kn-affil= affil-num=4 en-affil=Department of Chemistry, Faculty of Science, Menoufia University kn-affil= affil-num=5 en-affil=Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University kn-affil= affil-num=6 en-affil=Department of Chemistry, Faculty of Science, Menoufia University kn-affil= en-keyword=Metal complexes kn-keyword=Metal complexes en-keyword=Thiosemicarbazone kn-keyword=Thiosemicarbazone en-keyword=Antitumor kn-keyword=Antitumor en-keyword=Ehrlich tumor kn-keyword=Ehrlich tumor en-keyword=Ki67 kn-keyword=Ki67 en-keyword=P53 kn-keyword=P53 END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=3 article-no= start-page=656 end-page=660 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dysostosis in mucopolysaccharidosis type 2: A case of longitudinal follow up and literature review en-subtitle= kn-subtitle= en-abstract= kn-abstract= Mucopolysaccharidosis type 2 is a congenital lysosomal disease characterized by iduronate-2-sulfatase deficiency, which leads to excessive accumulation of glycosaminoglycans in tissue. Dysostosis, which primarily involves decreased bone mineralization with morphological changes in the bone, is a major skeletal condition in mucopolysaccharidosis, but its pathophysiology is not well known. Here, we report a case of mucopolysaccharidosis type 2 diagnosed at the age of 2 years with longitudinal follow-up data for more than 15 years. Although the patient underwent bone marrow transplantation, the developmental quotient did not improve, and cranial hyperostosis progressed prominently with a faintly dilated perivascular space. Other dysostoses and contraction of the joints were observed but did not improve either. en-copyright= kn-copyright= en-aut-name=SasakiTomoaki en-aut-sei=Sasaki en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OgataMiki en-aut-sei=Ogata en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KajihamaAya en-aut-sei=Kajihama en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakauKouichi en-aut-sei=Nakau en-aut-mei=Kouichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkizakiAtsutaka en-aut-sei=Okizaki en-aut-mei=Atsutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiology, Asahikawa Medical University kn-affil= affil-num=3 en-affil=Department of Pediatrics, Asahikawa Medical University kn-affil= affil-num=4 en-affil=Department of Pediatrics, Asahikawa Medical University kn-affil= affil-num=5 en-affil=Department of Radiology, Asahikawa Medical University kn-affil= en-keyword=Mucopolysaccharidosis type 2 kn-keyword=Mucopolysaccharidosis type 2 en-keyword=Dysostosis kn-keyword=Dysostosis en-keyword=Cranial hyperostosis kn-keyword=Cranial hyperostosis END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=100047 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The usefulness and safety of the simultaneous parallel anterior and posterior combined lumbar spine surgery using intraoperative 3D fluoroscopy-based navigation (SPAPS) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
The combined anterior-posterior surgery in the lateral decubitus position generally needs the intraoperative repositioning. However, prolonged surgical time and increased medical costs due to intraoperative repositioning have been problematic. In recent years, there have been reports of combined anterior-posterior procedure with a single position performing anterior and posterior fixation consecutively where the patient remains in the lateral decubitus position (single surgeon method-SS method). We had further advanced this method, and have adopted the Simultaneous Parallel Anterior and Posterior combined lumbar spine Surgery using intraoperative 3D fluoroscopy-based navigation (SPAPS method), where anterior and posterior procedure are performed independently by two spine surgeons.
Methods
66 cases that underwent SPAPS method (n=37) and SS method (n=29) from 2015 to 2019 at single institution were concluded in this study. The pre- and post-operative changes in the following were compared retrospectively between the two groups: surgical factors and clinical evaluations including JOA back pain evaluation questionnaire (JOABPEQ), visual analogue scale (VAS) on lower back pain, buttock/lower limb pain, and buttock/lower limb numbness, and Roland-Morris disability questionnaire (RDQ).
Results
The SPAPS method was able to significantly reduce the surgical time (p=0.0025) compared to the SS method, and allowed a reduction of approximately 24.4 minutes per segment. The estimated blood loss were similar in both groups, and with regards to post-operative outcomes, both groups improved equally well. The rates of screw deviation and fusion were also similar.
Conclusions
In the case of performing the combined anterior-posterior surgery under a single position, the anterior and posterior procedure can be performed independently and simultaneously by two spine surgeons by utilizing the 3D fluoroscopy-based navigation. The surgical time can be significantly reduced by approximately 24.4 minutes per segment comparing to the SS method. en-copyright= kn-copyright= en-aut-name=IkumaHisanori en-aut-sei=Ikuma en-aut-mei=Hisanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiroseTomohiko en-aut-sei=Hirose en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakaoShinichiro en-aut-sei=Takao en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OtsukaKazutoshi en-aut-sei=Otsuka en-aut-mei=Kazutoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawasakiKeisuke en-aut-sei=Kawasaki en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Kagawa Prefectural Central Hospital, kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Kagawa Prefectural Central Hospital, kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Science kn-affil= affil-num=4 en-affil=Otsuka Orthopaedic Surgery Clinic kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Kagawa Prefectural Central Hospital, kn-affil= en-keyword=Single position surgery kn-keyword=Single position surgery en-keyword=Lateral decubitus position kn-keyword=Lateral decubitus position en-keyword=Spine surgery kn-keyword=Spine surgery en-keyword=Navigation system kn-keyword=Navigation system en-keyword=Parallel kn-keyword=Parallel en-keyword=Independent kn-keyword=Independent END start-ver=1.4 cd-journal=joma no-vol=39 cd-vols= no-issue=3 article-no= start-page=180 end-page=190 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Catalog of prognostic tissue-based biomarkers in patients treated with neoadjuvant systemic therapy for urothelial carcinoma of the bladder: a systematic review en-subtitle= kn-subtitle= en-abstract= kn-abstract=PURPOSE
The present systematic review aimed to identify prognostic values of tissue-based biomarkers in patients treated with neoadjuvant systemic therapy (NAST), including chemotherapy (NAC) and checkpoint inhibitors (NAI) for urothelial carcinoma of the bladder (UCB).
MATERIAL AND METHODS
The PubMed, Web of Science, and Scopus databases were searched in August 2020 according to the PRISMA statement. Studies were deemed eligible if they compared oncologic or pathologic outcomes in patients treated with NAST for UCB with and without detected pretreatment tissue-based biomarkers.
RESULTS
Overall, 44 studies met our eligibility criteria. Twenty-three studies used immunohistochemistry (IHC), 19 ? gene expression analysis, three - quantitative polymerase chain reaction (QT PCR), and two ? next-generation sequencing (NGS). According to the currently available literature, predictive IHC-assessed biomarkers, such as receptor tyrosine kinases and DNA repair pathway alterations, do not seem to convincingly improve our prediction of pathologic response and oncologic outcomes after NAC. Luminal and basal tumor subtypes based on gene expression analysis showed better NAC response, while claudin-low and luminal-infiltrated tumor subtypes did not. In terms of NAI, PD-L1 seems to maintain value as a predictive biomarker, while the utility of both tumor mutational burden and molecular subtypes remains controversial. Specific genomic alterations in DNA repair genes have been shown to provide significant predictive value in patient treated with NAC. QT PCR quantification of specific genes selected through microarray analysis seems to classify cases regarding their NAC response.
CONCLUSION
We believe that the present systematic review may offer a robust framework that will enable the testing and validation of predictive biomarkers in future prospective clinical trials. NGS has expanded the discovery of molecular markers that are reflective of the mechanisms of the NAST response. en-copyright= kn-copyright= en-aut-name=LaukhtinaEkaterina en-aut-sei=Laukhtina

en-subtitle= kn-subtitle= en-abstract= kn-abstract= Environmental exposure to arsenic, a well-established carcinogen linked to a number of human cancers, is a public health concern in many areas of the world. Despite extensive studies on the molecular mechanisms of arsenic-induced carcinogenesis, how initial cellular responses, such as activation of stress kinases and the generation of reactive oxygen species, converge to affect the transcriptional and/or epigenetic reprogramming required for the malignant transformation of normal cells or normal stem cells remains to be elucidated. In this review, we discuss some recent discoveries showing how the transcription factor NRF2 and an epigenetic regulator, MDIG, contribute to the arsenic-induced generation of cancer stem-like cells (CSCs) as determined by applying CRISPR-Cas9 gene editing and chromosome immunoprecipitation followed by DNA sequencing (ChIP-seq). en-copyright= kn-copyright= en-aut-name=BiZhuoyue en-aut-sei=Bi en-aut-mei=Zhuoyue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZhangQian en-aut-sei=Zhang en-aut-mei=Qian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FuYao en-aut-sei=Fu en-aut-mei=Yao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SenoAkimasa en-aut-sei=Seno en-aut-mei=Akimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WadgaonkarPriya en-aut-sei=Wadgaonkar en-aut-mei=Priya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=QiuYiran en-aut-sei=Qiu en-aut-mei=Yiran kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AlmutairyBandar en-aut-sei=Almutairy en-aut-mei=Bandar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=XuLiping en-aut-sei=Xu en-aut-mei=Liping kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ZhangWenxuan en-aut-sei=Zhang en-aut-mei=Wenxuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ThakurChitra en-aut-sei=Thakur en-aut-mei=Chitra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ChenFei en-aut-sei=Chen en-aut-mei=Fei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Pharmaceutical Sciences, Eugene Applebaum College of Pharmacy and Health Sciences, Wayne State University kn-affil= affil-num=2 en-affil=Department of Pharmaceutical Sciences, Eugene Applebaum College of Pharmacy and Health Sciences, Wayne State University kn-affil= affil-num=3 en-affil=Department of Pharmaceutical Sciences, Eugene Applebaum College of Pharmacy and Health Sciences, Wayne State University kn-affil= affil-num=4 en-affil=Faculty of Engineering, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Pharmaceutical Sciences, Eugene Applebaum College of Pharmacy and Health Sciences, Wayne State University kn-affil= affil-num=6 en-affil=Department of Pharmaceutical Sciences, Eugene Applebaum College of Pharmacy and Health Sciences, Wayne State University kn-affil= affil-num=7 en-affil=Department of Pharmaceutical Sciences, Eugene Applebaum College of Pharmacy and Health Sciences, Wayne State University kn-affil= affil-num=8 en-affil=Department of Pharmaceutical Sciences, Eugene Applebaum College of Pharmacy and Health Sciences, Wayne State University kn-affil= affil-num=9 en-affil=Department of Pharmaceutical Sciences, Eugene Applebaum College of Pharmacy and Health Sciences, Wayne State University kn-affil= affil-num=10 en-affil=Department of Pharmaceutical Sciences, Eugene Applebaum College of Pharmacy and Health Sciences, Wayne State University kn-affil= affil-num=11 en-affil=Department of Pharmaceutical Sciences, Eugene Applebaum College of Pharmacy and Health Sciences, Wayne State University kn-affil= en-keyword=Arsenic kn-keyword=Arsenic en-keyword=NRF2 kn-keyword=NRF2 en-keyword=MDIG kn-keyword=MDIG en-keyword=Cancer stem cells kn-keyword=Cancer stem cells en-keyword=Carcinogenesis kn-keyword=Carcinogenesis END start-ver=1.4 cd-journal=joma no-vol=107 cd-vols= no-issue=2 article-no= start-page=244 end-page=245 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210430 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Les longueurs intra-articulaires des greffons ? double faisceau peuvent changer pendant la flexion du genou?: mesures perop?ratoires lors de reconstructions anatomiques du ligament crois? ant?rieur en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
The lengths of the anteromedial bundle (AMB) and posterolateral bundle (PLB) change during knee motion during double-bundle anterior cruciate ligament (ACL) reconstruction. However, the actual intra-articular graft length would be affected by the bone tunnel position and tunnel creation angle during ACL reconstruction. The aim of this study was to investigate the intra-articular length change of the AMB and PLB in patients who underwent anatomic double-bundle ACL reconstruction.
Hypothesis
We hypothesized that the PLB would show a more dynamic length change pattern than the AMB during knee flexion at ACL reconstruction.
Methods
Thirty-two patients (16?men and 16?women) who had isolated ACL injuries with intact menisci were investigated. Anatomic double-bundle ACL reconstructions were performed using semitendinosus tendon autografts at a mean age of 30.6?years. The graft and tunnel lengths were measured intraoperatively. Intra-articular graft lengths and length changes were calculated at 0‹ and 90‹ of knee flexion during ACL reconstruction. Intraoperative data were collected prospectively, and analyses were performed retrospectively.
Results
The intra-articular length of the AMB at 0‹ of knee flexion was 28.1}5.5mm. At 90‹ of knee flexion, the AMB intra-articular length decreased to 25.6}4.8mm. The intra-articular length of the PLB decreased to 17.7}4.6mm at 90‹ of knee flexion compared to 22.0}4.2mm at 0‹ of knee flexion. Changes in the intra-articular graft length during knee flexion were detected more in the PLB (4.1mm) than in the AMB (2.0mm, p=0.01).
Discussion
This study demonstrated that the intra-articular length change of the PLB during knee motion was larger than that of the AMB in anatomic double-bundle ACL reconstructions with semitendinosus tendon autografts and suspensory femoral fixation devices.

Sleep problems in adolescence, such as insomnia and short sleep duration, are associated with physical and mental health problems. However, little is known about the recent trends in sleep problems among adolescents. Therefore, this study examined trends in sleep problems among Japanese adolescents.
Methods
Using data from the Lifestyle Survey of Adolescents collected in 2004 (n?=?102,451), 2008 (n?=?95,680), 2010 (n?=?98,867), 2012 (n?=?101,134), 2014 (n?=?85,931), and 2017 (n?=?64,417), we calculated the trends of insomnia, shorter sleep duration, late bedtimes, and poor sleep quality. Multivariable logistic regression analysis models were used to examine the association of each sleep problem and survey years.
Findings
We analyzed data from 545,285 Japanese adolescents. Results indicated that, since 2004, the odds ratio for insomnia have decreased (Adjusted odds ratio [AOR] 0?85, 95% CI 0?82?0?87), as have the odds ratio for poor sleep quality (AOR 0?92, 95% CI 0?88?0?95). However, the odds ratio for shorter sleep duration (AOR 1?13, 95% CI 1?10?1?17) and late bedtimes tended to increase (AOR 1?06, 95% CI 1?03?1?08) during this period.
Interpretation
The prevalence of insomnia symptoms and poor sleep quality among adolescents decreased from 2004 to 2017. However, there were increasing trends toward shorter sleep duration and late bedtimes. These changes are both relieving and concerning. Teachers, parents, and health professionals should consider educating adolescents regarding sleep hygiene, adjusting schedules of extracurricular activities, and enhancing time management to improve their sleep quantity. en-copyright= kn-copyright= en-aut-name=OtsukaYuichiro en-aut-sei=Otsuka en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KaneitaYoshitaka en-aut-sei=Kaneita en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SpiraAdam P. en-aut-sei=Spira en-aut-mei=Adam P. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MojtabaiRamin en-aut-sei=Mojtabai en-aut-mei=Ramin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ItaniOsamu en-aut-sei=Itani en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=JikeMaki en-aut-sei=Jike en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HiguchiSusumu en-aut-sei=Higuchi en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KandaHideyuki en-aut-sei=Kanda en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KuwabaraYuki en-aut-sei=Kuwabara en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KinjoAya en-aut-sei=Kinjo en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OsakiYoneatsu en-aut-sei=Osaki en-aut-mei=Yoneatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Division of Public Health, Department of Social Medicine, Nihon University School of Medicine kn-affil= affil-num=2 en-affil=Division of Public Health, Department of Social Medicine, Nihon University School of Medicine kn-affil= affil-num=3 en-affil=Department of Mental Health, Bloomberg School of Public Health, Johns Hopkins University kn-affil= affil-num=4 en-affil=Department of Mental Health, Bloomberg School of Public Health, Johns Hopkins University kn-affil= affil-num=5 en-affil=Division of Public Health, Department of Social Medicine, Nihon University School of Medicine kn-affil= affil-num=6 en-affil=Division of Public Health, Department of Social Medicine, Nihon University School of Medicine kn-affil= affil-num=7 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=National Hospital Organization Kurihama Medical and Addiction Center kn-affil= affil-num=9 en-affil=Division of Environmental and Preventive Medicine, Department of Social Medicine, Faculty of Medicine, Tottori University kn-affil= affil-num=10 en-affil=Division of Environmental and Preventive Medicine, Department of Social Medicine, Faculty of Medicine, Tottori University kn-affil= affil-num=11 en-affil=Division of Environmental and Preventive Medicine, Department of Social Medicine, Faculty of Medicine, Tottori University kn-affil= en-keyword=Adolescence kn-keyword=Adolescence en-keyword=Sleep kn-keyword=Sleep en-keyword=Adolescent health kn-keyword=Adolescent health en-keyword=Trends kn-keyword=Trends en-keyword=Health surveys kn-keyword=Health surveys en-keyword=Insomnia kn-keyword=Insomnia END start-ver=1.4 cd-journal=joma no-vol=56 cd-vols= no-issue= article-no= start-page=70 end-page=77 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210430 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prospective cohort study of febrile neutropenia in breast cancer patients administered with neoadjuvant and adjuvant chemotherapies: CSPOR-BC FN study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
As Asians are more vulnerable to febrile neutropenia (FN) than Caucasians, evaluations of FN incidence and risk factors in Asians are important for the appropriate use of primary pegfilgrastim (PEG-G).
Patients and methods
Japanese breast cancer patients receiving standard adjuvant chemotherapies were prospectively enrolled in multicenter institutions from August 2015 to July 2017. FN was evaluated from 2 treatment policies: true FN (T-FN): ?37.5?‹C, grade 4 neutropenia, mandatory hospital visit (visiting); surrogate FN (S-FN): ?37.5?‹C, oral antibiotic, no mandatory visit (non-visiting). PEG-G was used at the physiciansf discretion. The primary endpoint was FN incidence during all cycles. Multivariate logistic regression analysis was performed to identify T-FN risk factors.
Results
Of 1005 enrolled patients, 980 women treated with FEC, E(A)C, and TC were analyzed. The FN incidence proportions in all patients were 22.5%, 27.5%, and 33.9% for FEC, E(A)C, and TC, respectively. Those of T-FN were 27.7%, 22.4%, and 36.6%; those of S-FN were 17.3%, 32.4%, and 31.5% with more frequent primary PEG-G usage. The relative dose intensity (RDI) of the 3 regimens was ?0.85 in both groups. In the analysis of risk factors, TC (odds ratio?=?2.67), age???65 years (2.24), and pretreatment absolute neutrophil count (ANC)/1000?ƒÊl (0.8) remained significant.
Conclusions
FN incidences were above 20% in the 3 regimens, with TC showing the highest. RDI was maintained at a high level in both visiting and non-visiting groups. Patient-related risk factors were age and pretreatment ANC. en-copyright= kn-copyright= en-aut-name=IshikawaTakashi en-aut-sei=Ishikawa en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakamakiKentaro en-aut-sei=Sakamaki en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NaruiKazutaka en-aut-sei=Narui en-aut-mei=Kazutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishimuraHideki en-aut-sei=Nishimura en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SangaiTakafumi en-aut-sei=Sangai en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TamakiKentaro en-aut-sei=Tamaki en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HasegawaYoshie en-aut-sei=Hasegawa en-aut-mei=Yoshie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeKen-ichi en-aut-sei=Watanabe en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SuganumaNobuyasu en-aut-sei=Suganuma en-aut-mei=Nobuyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MichishitaShintaro en-aut-sei=Michishita en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SugaeSadatoshi en-aut-sei=Sugae en-aut-mei=Sadatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=AiharaTomohiko en-aut-sei=Aihara en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TsugawaKoichiro en-aut-sei=Tsugawa en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=KaiseHirose en-aut-sei=Kaise en-aut-mei=Hirose kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=TairaNaruto en-aut-sei=Taira en-aut-mei=Naruto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=MukaiHirofumi en-aut-sei=Mukai en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Breast Surgery and Oncology, Tokyo Medical University kn-affil= affil-num=2 en-affil=Department of Biostatistics, Yokohama City University kn-affil= affil-num=3 en-affil=Department of Biostatistics, Yokohama City University kn-affil= affil-num=4 en-affil=Department of Biostatistics, Yokohama City University kn-affil= affil-num=5 en-affil=Department of Breast and Thyroid Surgery, Chiba University kn-affil= affil-num=6 en-affil=Naha-Nishi Clinic kn-affil= affil-num=7 en-affil=Department of Breast Surgery, Hirosaki Municipal Hospita kn-affil= affil-num=8 en-affil=Department of Breast Surgery, Hokkaido Cancer Center kn-affil= affil-num=9 en-affil=Department of Breast and Thyroid Surgery, Kanagawa Cancer Center kn-affil= affil-num=10 en-affil=Department of Breast Surgery, Yao Municipal Hospital kn-affil= affil-num=11 en-affil=Department of Gastroenterological Surgery, Yokohama City University Graduate School of Medicine kn-affil= affil-num=12 en-affil=Breast Center, Aihara Hospital kn-affil= affil-num=13 en-affil=Department of Breast and Thyroid Surgery, St. Marianna University kn-affil= affil-num=14 en-affil=Department of Breast Surgery and Oncology, Tokyo Medical University kn-affil= affil-num=15 en-affil=Department of Breast and Endocrinology Surgery, Okayama University Graduate School of Medicine kn-affil= affil-num=16 en-affil=Division of Oncology/Hematology, National Cancer Center Hospital East kn-affil= en-keyword=Breast cancer kn-keyword=Breast cancer en-keyword=Febrile neutropenia kn-keyword=Febrile neutropenia en-keyword=Adjuvant chemotherapy kn-keyword=Adjuvant chemotherapy en-keyword=Risk factors kn-keyword=Risk factors en-keyword=Prospective study kn-keyword=Prospective study END start-ver=1.4 cd-journal=joma no-vol=174 cd-vols= no-issue= article-no= start-page=111436 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201229 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Combined signal sequence trap and macroarray analysis identifies genes associated with differential fruit softening characteristics during ripening in European and Chinese pears en-subtitle= kn-subtitle= en-abstract= kn-abstract= During ripening, European pear (Pyrus communis L. cv. eLa Francef) fruit undergo dramatic softening in response to increased ethylene production, whereas Chinese pear (Pyrus bretschneideri Rehd. cv. eYalif) fruit remain firm, despite producing large amounts of ethylene. The molecular basis of this differential softening behavior is not well understood. In this study, we combined a yeast-based signal sequence trap (YSST) and macroarray gene expression analysis to identify putative genes encoding secreted proteins that control pear fruit softening. We identified 22 cDNAs annotated as encoding proteins with diverse cell wall-associated functions that were up- or down-regulated during fruit ripening in eLa Francef. Gene expression analysis in fruit that were treated with the ethylene perception inhibitor 1-methylcyclopropene (1-MCP) at 4 d after the onset of ripening revealed that 16 of the targeted genes are ethylene-regulated, while the others appear to be ethylene independent. Comparative gene expression analyses of eLa Francef and eYalif fruit during ripening suggested that four ethylene-regulated cDNAs encoding cell wall modifying proteins, contig 2 (polygalacturonase 3), contig 15 (expansin), contig 19 (expansin) and contig 55 (pectate lyase) contribute to the different softening behaviors of eLa Francef and eYalif fruit. Additionally, one ethylene-independent cell wall related gene, contig 36 (expansin), and three genes encoding proteins of unknown function, contigs 1, 13 and contig 75 showed differential expression between eLa Francef and eYalif fruit during ripening. The results presented herein represent promising candidates for future functional analysis and elucidation of softening mechanisms. en-copyright= kn-copyright= en-aut-name=MwanikiMercy W. en-aut-sei=Mwaniki en-aut-mei=Mercy W. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitaloOscar W. en-aut-sei=Mitalo en-aut-mei=Oscar W. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MworiaEric G. en-aut-sei=Mworia en-aut-mei=Eric G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OwinoWillis O. en-aut-sei=Owino en-aut-mei=Willis O. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Hiwasa-TanaseKyoko en-aut-sei=Hiwasa-Tanase en-aut-mei=Kyoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=RoseJocelyn K.C. en-aut-sei=Rose en-aut-mei=Jocelyn K.C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AokiKoh en-aut-sei=Aoki en-aut-mei=Koh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=EsumiTomoya en-aut-sei=Esumi en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KawaiTakashi en-aut-sei=Kawai en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakanoRyohei en-aut-sei=Nakano en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=UshijimaKoichiro en-aut-sei=Ushijima en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KuboYasutaka en-aut-sei=Kubo en-aut-mei=Yasutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Life and Environmental Sciences, University of Tsukuba kn-affil= affil-num=6 en-affil=Plant Biology Section, School of Integrative Plant Science, Cornell University kn-affil= affil-num=7 en-affil=Graduate School of Life and Environmental Sciences, Osaka Prefecture University kn-affil= affil-num=8 en-affil=Academic Assembly Institute of Agricultural and Life Sciences, Shimane University kn-affil= affil-num=9 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=10 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=12 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=YSST kn-keyword=YSST en-keyword= eLa Francef kn-keyword= eLa Francef en-keyword=eYalif kn-keyword=eYalif en-keyword=Polygalacturonase kn-keyword=Polygalacturonase en-keyword=Expansin kn-keyword=Expansin en-keyword=Pectate lyase kn-keyword=Pectate lyase END start-ver=1.4 cd-journal=joma no-vol=110 cd-vols= no-issue= article-no= start-page=1788 end-page=1798 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210430 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lactosome-Conjugated siRNA Nanoparticles for Photo-Enhanced Gene Silencing in Cancer Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=The A3B-type Lactosome comprised of poly(sarcosine)3-block-poly(l-lactic acid), a biocompatible and biodegradable polymeric nanomicelle, was reported to accumulate in tumors in?vivo via the enhanced permeability and retention (EPR) effect. Recently, the cellular uptake of Lactosome particles was enhanced through the incorporation of a cell-penetrating peptide (CPP), L7EB1. However, the ability of Lactosome as a drug delivery carrier has not been established. Herein, we have developed a method to conjugate the A3B-type Lactosome with ATP-binding cassette transporter G2 (ABCG2) siRNA for inducing in?vitro apoptosis in the cancer cell lines PANC-1 and NCI-H226. The L7EB1 peptide facilitates the cellular uptake efficiency of Lactosome but does not deliver siRNA into cytosol. To establish the photoinduced cytosolic dispersion of siRNA, a photosensitizer loaded L7EB1-Lactosome was prepared, and the photosensitizer 5,10,15,20-tetra-kis(pentafluorophenyl)porphyrin (TPFPP) showed superiority in photoinduced cytosolic dispersion. We exploited the combined effects of enhanced cellular uptake by L7EB1 and photoinduced endosomal escape by TPFPP to efficiently deliver ABCG2 siRNA into the cytosol for gene silencing. Moreover, the silencing of ABCG2, a protoporphyrin IX (PpIX) transporter, also mediated photoinduced cell death via 5-aminolevulinic acid (ALA)-mediated PpIX accumulated photodynamic therapy (PDT). The synergistic capability of the L7EB1/TPFPP/siRNA-Lactosome complex enabled both gene silencing and PDT. en-copyright= kn-copyright= en-aut-name=LimMelissa Siaw Han en-aut-sei=Lim en-aut-mei=Melissa Siaw Han kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiyamaYuki en-aut-sei=Nishiyama en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhtsukiTakashi en-aut-sei=Ohtsuki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeKazunori en-aut-sei=Watanabe en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobuchiHirotsugu en-aut-sei=Kobuchi en-aut-mei=Hirotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KobayashiKazuko en-aut-sei=Kobayashi en-aut-mei=Kazuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuuraEiji en-aut-sei=Matsuura en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil= kn-affil= affil-num=6 en-affil=Collaborative Research Center (OMIC), Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil= kn-affil= en-keyword=Lactosome kn-keyword=Lactosome en-keyword=ABCG2 kn-keyword=ABCG2 en-keyword=siRNA kn-keyword=siRNA en-keyword=Cancer kn-keyword=Cancer en-keyword=siRNA delivery kn-keyword=siRNA delivery en-keyword=Photodynamic therapy kn-keyword=Photodynamic therapy en-keyword=Polymeric micelle kn-keyword=Polymeric micelle en-keyword=Photosensitizer kn-keyword=Photosensitizer en-keyword=Photochemical internalization kn-keyword=Photochemical internalization END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=100044 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structural basis of enzyme activity regulation by the propeptide of l-lysine ƒ¿-oxidase precursor from Trichoderma viride en-subtitle= kn-subtitle= en-abstract= kn-abstract=Harmuful proteins are usually synthesized as inactive precursors and are activated by proteolytic processing. l-Amino acid oxidase (LAAO) is a flavoenzyme that catalyzes the oxidative deamination of l-amino acid to produce a 2-oxo acid with ammonia and highly toxic hydrogen peroxide and, therefore, is expressed as a precursor. The LAAO precursor shows significant variation in size and the cleavage pattern for activation. However, the molecular mechanism of how the propeptide suppresses the enzyme activity remains unclear except for deaminating/decarboxylating Pseudomonasl-phenylalanine oxidase (PAO), which has a short N-terminal propeptide composed of 14 residues. Here we show the inactivation mechanism of the l-lysine oxidase (LysOX) precursor (prLysOX), which has a long N-terminal propeptide composed of 77 residues, based on the crystal structure at 1.97?? resolution. The propeptide of prLysOX indirectly changes the active site structure to inhibit the enzyme activity. prLysOX retains weak enzymatic activity with strict specificity for l-lysine and shows raised activity in acidic conditions. The structures of prLysOX crystals that soaked in a solution with various concentrations of l-lysine have revealed that prLysOX can adopt two conformations; one is the inhibitory form, and the other is very similar to mature LysOX. The propeptide region of the latter form is disordered, and l-lysine is bound to the latter form. These results indicate that prLysOX uses a different strategy from PAO to suppress the enzyme activity and suggest that prLysOX can be activated quickly in response to the environmental change without proteolytic processing. en-copyright= kn-copyright= en-aut-name=KitagawaMasaki en-aut-sei=Kitagawa en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ItoNanako en-aut-sei=Ito en-aut-mei=Nanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsumotoYuya en-aut-sei=Matsumoto en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoMasaya en-aut-sei=Saito en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TamuraTakashi en-aut-sei=Tamura en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KusakabeHitoshi en-aut-sei=Kusakabe en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=InagakiKenji en-aut-sei=Inagaki en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ImadaKatsumi en-aut-sei=Imada en-aut-mei=Katsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Macromolecular Science, Graduate School of Science, Osaka University kn-affil= affil-num=2 en-affil=Department of Macromolecular Science, Graduate School of Science, Osaka University kn-affil= affil-num=3 en-affil=Department of Biofunctional Chemistry, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Biofunctional Chemistry, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Biofunctional Chemistry, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Enzyme Sensor Co., Ltd. kn-affil= affil-num=7 en-affil=Department of Biofunctional Chemistry, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=8 en-affil=Department of Macromolecular Science, Graduate School of Science, Osaka University kn-affil= en-keyword=L-Lysine ƒ¿-oxidase kn-keyword=L-Lysine ƒ¿-oxidase en-keyword=Crystal structure kn-keyword=Crystal structure en-keyword=Precursor kn-keyword=Precursor en-keyword=Substrate recognition kn-keyword=Substrate recognition END start-ver=1.4 cd-journal=joma no-vol=296 cd-vols= no-issue= article-no= start-page=100524 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Covalent N-arylation by the pollutant 1,2-naphthoquinone activates the EGF receptor en-subtitle= kn-subtitle= en-abstract= kn-abstract=The epidermal growth factor receptor (EGFR) is the most intensively investigated receptor tyrosine kinase. Several EGFR mutations and modifications have been shown to lead to abnormal self-activation, which plays a critical role in carcinogenesis. Environmental air pollutants, which are associated with cancer and respiratory diseases, can also activate EGFR. Specifically, the environmental electrophile 1,2-naphthoquinone (1,2-NQ), a component of diesel exhaust particles and particulate matter more generally, has previously been shown to impact EGFR signaling. However, the detailed mechanism of 1,2-NQ function is unknown. Here, we demonstrate that 1,2-NQ is a novel chemical activator of EGFR but not other EGFR family proteins. We found that 1,2-NQ forms a covalent bond, in a reaction referred to as N-arylation, with Lys80, which is in the ligand-binding domain. This modification activates the EGFR?Akt signaling pathway, which inhibits serum deprivation?induced cell death in a human lung adenocarcinoma cell line. Our study reveals a novel mode of EGFR pathway activation and suggests a link between abnormal EGFR activation and environmental pollutant?associated diseases such as cancer. en-copyright= kn-copyright= en-aut-name=NakaharaKengo en-aut-sei=Nakahara en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamadaKyohei en-aut-sei=Hamada en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsuchidaTomoki en-aut-sei=Tsuchida en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakasugiNobumasa en-aut-sei=Takasugi en-aut-mei=Nobumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AbikoYumi en-aut-sei=Abiko en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShienKazuhiko en-aut-sei=Shien en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KumagaiYoshito en-aut-sei=Kumagai en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UeharaTakashi en-aut-sei=Uehara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Environmental Biology Laboratory, Faculty of Medicine, University of Tsukuba kn-affil= affil-num=6 en-affil=Department of Thoracic, Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Thoracic, Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Environmental Biology Laboratory, Faculty of Medicine, University of Tsukuba kn-affil= affil-num=9 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=epidermal growth factor receptor kn-keyword=epidermal growth factor receptor en-keyword=cell signaling kn-keyword=cell signaling en-keyword=chemical modification kn-keyword=chemical modification en-keyword=signal transduction kn-keyword=signal transduction en-keyword=apoptosis kn-keyword=apoptosis END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue= article-no= start-page=52 end-page=62 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dioxin sources to the aquatic environment: Re-assessing dioxins in industrial processes and possible emissions to the aquatic en-subtitle= kn-subtitle= en-abstract= kn-abstract=Releases of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/PCDFs) from industrial or thermal processes to the aquatic environment are considered small compared to emissions to air today. However, industrial processes have occasionally released PCDD/PCDFs into local aquatic environments. . PCDD/PCDF formation and releases were re-examined based on investigations conducted before the introduction of water quality regulations in Japan. Emphasis was given to PCDD/PCDF formation in various industrial processes such as the manufacture of acetylene and caprolactam.In acetylene production, PCDD/PCDFs are formed in the oxidative process using chlorine to remove impurities, with PCDFs formed with the particular chlorine pattern with 1,2,7,8-TetraCDF, 2,3,7,8-TetraCDFs and 1,2,3,4,7,8-HexaCDF as maker congeners and low PCDDs levels. This indicates that acetylene production residues contain organochlorines.In caprolactam production, formation of PCDD/PCDFs in the cyclohexane photonitrosation process has been confirmed and the emission factor for PCDD/PCDF releases to water from for caprolactam manufacture was estimated with an emission factor for releases to the aquatic environment of 0.25?}?0.04?ƒÊg-TEQ/t.A range of additional processes with PCDD/PCDF release were also found during the Japanese survey. Overall, the formation processes were placed in two categories: A) chemical synthesis processes and B) flue gas treatment of high temperature processes. The final effluent water met the PCDD/PCDF limits by applying advanced treatment for PCDD/PCDF removal such as activated carbon treatment. The survey shows that industrial processes involving elemental chlorine or other processes that facilitate chlorination or use chlorinating chemicals should be assessed and controlled for PCDD/PCDFs and other unintentional POPs releases to water. In such surveys, chemicals from the chlorine and organochlorine industry should also be assessed for PCDD/PCDFs and other unintentional POPs contamination as proposed by the UNEP Toolkit. The current study can contribute to the Stockholm Convention implementation of Article 5 of the Stockholm Convention to take measures to reduce the release of UPOPs from anthropogenic sources with the goal of their continuing minimization and, where feasible, ultimate elimination. en-copyright= kn-copyright= en-aut-name=KawamotoKatsuya en-aut-sei=Kawamoto en-aut-mei=Katsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WeberRoland en-aut-sei=Weber en-aut-mei=Roland kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=POPs Environmental Consulting, kn-affil= en-keyword=PCDD/PCDF kn-keyword=PCDD/PCDF en-keyword=Water pollutionIndustrial sources kn-keyword=Water pollutionIndustrial sources en-keyword=Acetylene manufacturing kn-keyword=Acetylene manufacturing en-keyword=Caprolactam manufacturing kn-keyword=Caprolactam manufacturing en-keyword=Pattern kn-keyword=Pattern en-keyword=Unintentional POPs kn-keyword=Unintentional POPs END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=12 end-page=16 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201230 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Inhibitory effects of RAGE-aptamer on development of monocrotaline-induced pulmonary arterial hypertension in rats en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The receptor for advanced glycation end products (RAGE), a transmembrane receptor belonging to the immunoglobulin superfamily, is overexpressed in pulmonary artery smooth muscle cells (PASMCs) in patients with pulmonary arterial hypertension (PAH) and is implicated in the etiology of PAH. Recently, we reported that RAGE-aptamer, a short and single-stranded DNA directed against RAGE, inhibited an inappropriate increase in cultured PASMCs in PAH. The aim of this study was to determine the efficacy of RAGEaptamer in monocrotaline-induced PAH in rats.

Methods and Results: Rats were assigned to either an untreated control group, a group that received continuous subcutaneous administration of RAGE-aptamer immediately after monocrotaline injection, or a group that received control-aptamer immediately after monocrotaline injection. All rats survived 21 days after injection of monocrotaline and control-aptamer or RAGE-aptamer. Injection of monocrotaline with continuous subcutaneous delivery of control-aptamer resulted in higher right ventricular systolic pressure compared with controls. This increase was attenuated by continuous subcutaneous delivery of RAGE-aptamer. The proportion of small pulmonary arteries with full muscularization was greater in the monocrotaline and control-aptamer group than in the control group. Continuous subcutaneous delivery of RAGE-aptamer significantly reduced the percentage of small pulmonary arteries with full muscularization Conclusions: Continuous subcutaneous delivery of RAGE-aptamer suppresses development of monocrotaline-induced PAH in rats. Inhibition of RAGE ameliorates muscularization of 3 small pulmonary arteries. Treatment with RAGE-aptamer might be a new therapeutic option for PAH. en-copyright= kn-copyright= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AkagiSatoshi en-aut-sei=Akagi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EjiriKentaro en-aut-sei=Ejiri en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaMasashi en-aut-sei=Yoshida en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakaguchiMasakiyo en-aut-sei=Sakaguchi en-aut-mei=Masakiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AmiokaNaofumi en-aut-sei=Amioka en-aut-mei=Naofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SuastikaLuh Oliva Saraswati en-aut-sei=Suastika en-aut-mei=Luh Oliva Saraswati kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KondoMegumi en-aut-sei=Kondo en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakayamaRie en-aut-sei=Nakayama en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TakayaYoichi en-aut-sei=Takaya en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HigashimotoYuichiro en-aut-sei=Higashimoto en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=FukamiKei en-aut-sei=Fukami en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MatsubaraHiromi en-aut-sei=Matsubara en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Chemistry, Kurume University School of Medicine kn-affil= affil-num=13 en-affil=Division of Nephrology, Department of Medicine, Kurume University School of Medicine kn-affil= affil-num=14 en-affil=Department of Cardiology, National Hospital Organization Okayama Medical Center kn-affil= affil-num=15 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=pulmonary artery smooth muscle cells kn-keyword=pulmonary artery smooth muscle cells en-keyword=RAGE kn-keyword=RAGE en-keyword=aptamer kn-keyword=aptamer END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue= article-no= start-page=093056 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190924 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Superconductivity in a new layered triangular-lattice system Li2IrSi2 en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report on the crystal structure and superconducting properties of a novel iridium-silicide, namely Li2IrSi2.

We estimated the following superconducting parameters: lower critical field Hc1(0) ~ 42 Oe, upper critical field Hc2(0) ~ 1.7 kOe, penetration depth ƒÉ0 ~ 265 nm, coherence length ƒÌ0 ~ 44 nm, and Ginzburg?Landau parameter ƒÈGL ~ 6.02. The specific-heat data suggested that superconductivity in Li2IrSi2 could be attributed to weak-coupling Cooper pairs. en-copyright= kn-copyright= en-aut-name=HoriganeK en-aut-sei=Horigane en-aut-mei=K kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeuchiK en-aut-sei=Takeuchi en-aut-mei=K kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HyakumuraD en-aut-sei=Hyakumura en-aut-mei=D kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HorieR en-aut-sei=Horie en-aut-mei=R kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SatoT en-aut-sei=Sato en-aut-mei=T kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MuranakaT en-aut-sei=Muranaka en-aut-mei=T kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawashimaK en-aut-sei=Kawashima en-aut-mei=K kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IshiiH en-aut-sei=Ishii en-aut-mei=H kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KubozonoY en-aut-sei=Kubozono en-aut-mei=Y kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OrimoS en-aut-sei=Orimo en-aut-mei=S kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IsobeM en-aut-sei=Isobe en-aut-mei=M kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=AkimitsuJ en-aut-sei=Akimitsu en-aut-mei=J kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University, kn-affil= affil-num=2 en-affil=Graduate School of natural science and technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Physics and Mathematics, Aoyama Gakuin University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=5 en-affil=Institute for Materials Research, Tohoku University kn-affil= affil-num=6 en-affil=Department of Engineering Science, University of Electro-Communications kn-affil= affil-num=7 en-affil=Department of Physics and Mathematics, Aoyama Gakuin University kn-affil= affil-num=8 en-affil=National Synchrotron Radiation Research Center kn-affil= affil-num=9 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=10 en-affil=Institute for Materials Research, Tohoku University kn-affil= affil-num=11 en-affil=National Institute for Materials Science (NIMS) kn-affil= affil-num=12 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=supreconductivity kn-keyword=supreconductivity en-keyword=iridium-silicide kn-keyword=iridium-silicide en-keyword=spin?orbit coupling kn-keyword=spin?orbit coupling END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=2 article-no= start-page=202 end-page=209 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20181214 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The novel latex agglutination turbidimetric immunoassay system for simultaneous measurements of calprotectin and hemoglobin in feces en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Aims
Fecal calprotectin (Fcal) as well as the fecal immunochemical test (FIT) are useful biomarkers for detecting activity and mucosal healing in inflammatory bowel diseases. Here, we report the performance of simultaneous measurements of Fcal and FIT for ulcerative colitis (UC) patients using the newly-developed latex agglutination turbidimetric immunoassay (LATIA) system.
Methods
Fcal and hemoglobin were measured by the LATIA system in 152 UC patients who underwent colonoscopy. Fcal was also quantified with a conventional enzyme-linked immunosorbent assay (ELISA). Fecal markers were evaluated in conjunction with the mucosal status of UC, which was assessed via the Mayo endoscopic subscore (MES) classification.
Results
The LATIA system could quantify calprotectin and hemoglobin simultaneously with the same fecal samples within 10 minutes. The values of the Fcal-LATIA closely correlated with those of the Fcal-ELISA (Spearman rank correlation coefficient, r=0.84; P<0.0001). The values of Fcal for each assay and the FIT all significantly correlated with the MESs (Spearman rank correlation coefficient, Fcal-LATIA: r=0.58, Fcal-ELISA: r=0.55, and FIT: r=0.72). The mucosal healing predictability (determined by an MES of 0 alone) of the Fcal-LATIA, Fcal-ELISA, and FIT-LATIA with the cutoffs determined by receiver operating characteristic curve analysis was 0.79, 0.78, and 0.92 for sensitivity, respectively, and 0.78, 0.69, and 0.73 for specificity, respectively.
Conclusions
The performance of the novel Fcal-LATIA was equivalent to that of the conventional Fcal assay. Simultaneous measurements with FITs would promote the clinical relevance of fecal biomarkers in UC. en-copyright= kn-copyright= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakashimaShiho en-aut-sei=Takashima en-aut-mei=Shiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InokuchiToshihiro en-aut-sei=Inokuchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakaraiAsuka en-aut-sei=Nakarai en-aut-mei=Asuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakaharaMasahiro en-aut-sei=Takahara en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HaradaKeita en-aut-sei=Harada en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SekiYasuhiro en-aut-sei=Seki en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeKatsunori en-aut-sei=Watanabe en-aut-mei=Katsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KatoJun en-aut-sei=Kato en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Endoscopy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Biochemical Research Laboratory-I, Eiken Chemical Co., Ltd. kn-affil= affil-num=8 en-affil=Department of Biochemical Research Laboratory-I, Eiken Chemical Co., Ltd. kn-affil= affil-num=9 en-affil=Department of Gastroenterology, Mitsui Memorial Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Colitis kn-keyword=Colitis en-keyword=ulcerative kn-keyword=ulcerative en-keyword=Fecal calprotectin kn-keyword=Fecal calprotectin en-keyword=Quantitative fecal immunochemical test kn-keyword=Quantitative fecal immunochemical test en-keyword=Latex agglutination turbidimetric immunoassay kn-keyword=Latex agglutination turbidimetric immunoassay en-keyword=Mucosal healing kn-keyword=Mucosal healing END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=1 article-no= start-page=55 end-page=61 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202102 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Thoracoscopic Localization of Small Peripheral Pulmonary Lesions Using Percutaneous Computed Tomography-guided Pleural Dye Marking: A Retrospective Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Small pulmonary lesions are often difficult to localize during thoracoscopic surgery. We describe a new com-puted tomography (CT)-guided pleural dye-marking method for small peripheral pulmonary lesions that does not involve a visceral pleural puncture. We used this technique for 23 lesions (22 patients) who underwent tho-racoscopic partial lung resection (Nov. 2016-Jan. 2018). With the patient in the lateral decubitus position, pre-operative CT-guided marking on the skin over the lesion was performed. During the surgery, we marked the visceral pleura with a skin marker directly or with an infant-size nutrition catheter with crystal violet at the tip through a venous indwelling needle inserted perpendicular to the skin marking. We localized and resected the lesions in all cases, without complications. The median nodule size measured histopathologically was 8 (4-20) mm overall, and 7 (0-20) mm of the solid part; the median distance from the visceral pleura to the nodule was 9 (1-33) mm. The median operation time was 67 (37-180) min. The median postoperative hospital stay was 3 (3-11) days. Our CT-guided pleural dye-marking method is useful and safe for the localization of small periph-eral pulmonary lesions in thoracoscopic partial lung resections. en-copyright= kn-copyright= en-aut-name=KuboYujiro en-aut-sei=Kubo en-aut-mei=Yujiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WatanabeMototsugu en-aut-sei=Watanabe en-aut-mei=Mototsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ChoshiHaruki en-aut-sei=Choshi en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsubaraKei en-aut-sei=Matsubara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShiotaniToshio en-aut-sei=Shiotani en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KataokaKazuhiko en-aut-sei=Kataoka en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Thoracic Surgery, Iwakuni Clinical Center kn-affil= affil-num=2 en-affil=Department of Thoracic Surgery, Iwakuni Clinical Center kn-affil= affil-num=3 en-affil=Department of Thoracic Surgery, Iwakuni Clinical Center kn-affil= affil-num=4 en-affil=Department of Thoracic Surgery, Iwakuni Clinical Center kn-affil= affil-num=5 en-affil=Department of Thoracic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Thoracic Surgery, Iwakuni Clinical Center kn-affil= en-keyword=Small pulmonary lesion kn-keyword=Small pulmonary lesion en-keyword=ground glass nodule kn-keyword=ground glass nodule en-keyword=marking kn-keyword=marking en-keyword=localization kn-keyword=localization en-keyword=thoracocentesis kn-keyword=thoracocentesis END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue= article-no= start-page=085134 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210222 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Successive destruction of charge density wave states by pressure in LaAgSb2 en-subtitle= kn-subtitle= en-abstract= kn-abstract=We comprehensively studied the magnetotransport properties of LaAgSb2 under high pressure up to 4 GPa, which showed unique successive charge density wave (CDW) transitions at TCDW1?210 K and TCDW2?190 K at ambient pressure. With the application of pressure, both TCDW1 and TCDW2 were suppressed and disappeared at the critical pressures of PCDW1=3.0?3.4 GPa and PCDW2=1.5?1.9 GPa, respectively. At PCDW1, the Hall conductivity showed a steplike increase, which is consistently understood by the emergence of a two-dimensional hollow Fermi surface at PCDW1. We also observed a significant negative magnetoresistance effect when the magnetic field and current were applied parallel to the c axis. The negative contribution was observed in the whole pressure region from 0 to 4 GPa. Shubnikov?de Haas (SdH) oscillation measurements under pressure directly showed the changes in the Fermi surface across the CDW phase boundaries. In PPCDW1, we observed a single frequency of ?48 T with a cyclotron effective mass of 0.066m0, whose cross section in the reciprocal space corresponded to only 0.22% of the first Brillouin zone. Besides, we observed another oscillation component with frequency of ?9.2 T, which is significantly enhanced in the limited pressure range of PCDW2 The histological diagnosis of autoimmune pancreatitis (AIP) by an endoscopic ultrasound (EUS)-guided approach is still challenging.
Methods
We investigated the utility of the 21-gauge Menghini-type biopsy needle with the rolling method for the histological diagnosis of AIP, in comparison with conventional 22-gauge needles. Among total 28 patients, rate of definitive histological diagnosis, acquired sample area of tissue, rate of histopathological diagnosis of AIP, and adverse events were retrospectively analyzed.
Results
Definitive histological diagnoses were successfully accomplished in all 14 patients (100%) treated with a Menghini-type needle, and in 57% of cases (8/14) treated with conventional 22-gauge needles (P? Conclusion
EUS-guided rolling method with the 21-gauge Menghini-type biopsy needle is useful for the histopathological diagnosis of AIP, due to its abundant acquisition of good-quality tissue from the pancreas.

Our evaluation of the phase behaviors is performed by setting up quantum partition functions with variable pressures on the basis of a rigorous statistical mechanics theory that requires only the intermolecular interactions as input. Noble gases, hydrocarbons, nitrogen, and oxygen are chosen as the guest species, which are key components of the volatiles in such satellites. We explore the hydrate/water two-phase boundary of those clathrate hydrates in water-rich conditions and the hydrate/guest two-phase boundary in guest-rich conditions, either of which occurs on the surface or subsurface of icy satellites. The obtained phase diagrams indicate that clathrate hydrates can be in equilibrium with either water or the guest species over a wide range far distant from the three-phase coexistence condition and that the stable pressure zone of each clathrate hydrate expands significantly on intense cooling. The implication of our findings for the stable form of water in Titan is that water on the surface exists only as clathrate hydrate with the atmosphere down to a shallow region of the crust, but clathrate hydrate in the remaining part of the crust can coexist with water ice. This is in sharp contrast to the surfaces of Europa and Ganymede, where the thin oxygen air coexists exclusively with pure ice. en-copyright= kn-copyright= en-aut-name=TanakaHideki en-aut-sei=Tanaka en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YagasakiTakuma en-aut-sei=Yagasaki en-aut-mei=Takuma kn-aut-name=‘ô kn-aut-sei= kn-aut-mei=‘ô aut-affil-num=2 ORCID= en-aut-name=MatsumotoMasakazu en-aut-sei=Matsumoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200615 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A novel difficulty grading system for laparoscopic living donor nephrectomy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Several difficulty grading systems have been developed as a useful tool for selecting patients and training surgeons in laparoscopic procedures. However, there is little information on predicting the difficulty of laparoscopic donor nephrectomy (LDN). The aim of this study was to develop a grading system to predict the difficulty of LDN.
Methods
Data of 1741 living donors, who underwent pure or hand-assisted LDN between 1994 and 2018 were analyzed. Multivariable analyses were performed to identify factors associated with prolonged operative time, defined as a difficulty index with 0 to 8. The difficulty of LDN was classified into three levels based on the difficulty index.
Results
Multivariable analyses identified that male (odds ratio [OR] 1.69, 95% CI 1.37?2.09, P??28 (OR 1.36, 95% CI 1.08?1.72, P?=?0.009), pure LDN (OR 1.99, 95% CI 1.53?2.60, P? Conclusion
We developed a novel grading system with simple preoperative donor factors to predict the difficulty of LDN. This grading system may help surgeons in patient selection to advance their experiences and/or teach fellows from simple to difficult LDN. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimenaiHendrikus J.
