The number of DCX-positive cells in tissues reportedly correlates with cancer progression; however, little is known about the mechanism by which these cells affect cancer progression. Here we demonstrated that DCX-positive cells, which are found in all major histological subtypes of lung cancer, are cancer-associated Schwann cells (CAS) and contribute to the chemoresistance of lung cancer cells by establishing an adrenergic microenvironment. Mechanistically, the activation of the Hippo transducer YAP/TAZ was involved in the acquisition of new traits of CAS and DCX positivity. We further revealed that CAS express catecholamine-synthesizing enzymes and synthesize adrenaline, which potentiates the chemoresistance of lung cancer cells through the activation of YAP/TAZ. Our findings shed light on CAS, which drive the formation of an adrenergic microenvironment by the reciprocal regulation of YAP/TAZ in lung cancer tissues. en-copyright= kn-copyright= en-aut-name=OtaniYusuke en-aut-sei=Otani en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatayamaHaruyoshi en-aut-sei=Katayama en-aut-mei=Haruyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ZhuYidan en-aut-sei=Zhu en-aut-mei=Yidan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HuangRongsheng en-aut-sei=Huang en-aut-mei=Rongsheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShigehiraTakafumi en-aut-sei=Shigehira en-aut-mei=Takafumi 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=SuzawaKen en-aut-sei=Suzawa en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=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= en-aut-name=FujimuraAtsushi en-aut-sei=Fujimura en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 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=4 en-affil=Department of Trauma Orthopedics, The Second Hospital of Dalian Medical University kn-affil= affil-num=5 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 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=7 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=8 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=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= affil-num=11 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=adrenaline kn-keyword=adrenaline en-keyword=cancer-associated Schwann cells kn-keyword=cancer-associated Schwann cells en-keyword=doublecortin kn-keyword=doublecortin en-keyword=microenvironment kn-keyword=microenvironment en-keyword=YAP/TAZ kn-keyword=YAP/TAZ END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=10 article-no= start-page=e4763 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Molecular mechanism of the common and opposing cosolvent effects of fluorinated alcohol and urea on a coiled coil protein en-subtitle= kn-subtitle= en-abstract= kn-abstract=Alcohols and urea are widely used as effective protein denaturants. Among monohydric alcohols, 2,2,2-trifluoroethanol (TFE) has large cosolvent effects as a helix stabilizer in proteins. In contrast, urea efficiently denatures ordered native structures, including helices, into coils. These opposing cosolvent effects of TFE and urea are well known, even though both preferentially bind to proteins; however, the underlying molecular mechanism remains controversial. Cosolvent-dependent relative stability between native and denatured states is rigorously related to the difference in preferential binding parameters (PBPs) between these states. In this study, GCN4-p1 with two-stranded coiled coil helices was employed as a model protein, and molecular dynamics simulations for the helix dimer and isolated coil were conducted in aqueous solutions with 2 M TFE and urea. As 2 M cosolvent aqueous solutions did not exhibit clustering of cosolvent molecules, we were able to directly investigate the molecular origin of the excess PBP without considering the enhancement effect of PBPs arising from the concentration fluctuations. The calculated excess PBPs of TFE for the helices and those of urea for the coils were consistent with experimentally observed stabilization of helix by TFE and that of coil by urea. The former was caused by electrostatic interactions between TFE and side chains of the helices, while the latter was attributed to both electrostatic and dispersion interactions between urea and the main chains. Unexpectedly, reverse-micelle-like orientations of TFE molecules strengthened the electrostatic interactions between TFE and the side chains, resulting in strengthening of TFE solvation. en-copyright= kn-copyright= en-aut-name=NakataNoa en-aut-sei=Nakata en-aut-mei=Noa 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= en-aut-name=MoritaTakeshi en-aut-sei=Morita en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ImamuraHiroshi en-aut-sei=Imamura en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Information Science, University of Hyogo 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= affil-num=5 en-affil=Department of Chemistry, Graduate School of Science, Chiba University kn-affil= affil-num=6 en-affil=Department of Bio-Science, Nagahama Institute of Bio-Science and Technology kn-affil= en-keyword=2,2,2-trifluoroethanol kn-keyword=2,2,2-trifluoroethanol en-keyword=cosolvent effects kn-keyword=cosolvent effects en-keyword=preferential binding parameter kn-keyword=preferential binding parameter en-keyword=protein folding stability kn-keyword=protein folding stability en-keyword=urea kn-keyword=urea 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=20240411 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Artificial intelligence to detect noise events in remote monitoring data en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Remote monitoring (RM) of cardiac implantable electrical devices (CIEDs) can detect various events early. However, the diagnostic ability of CIEDs has not been sufficient, especially for lead failure. The first notification of lead failure was almost noise events, which were detected as arrhythmia by the CIED. A human must analyze the intracardiac electrogram to accurately detect lead failure. However, the number of arrhythmic events is too large for human analysis. Artificial intelligence (AI) seems to be helpful in the early and accurate detection of lead failure before human analysis.
Objective: To test whether a neural network can be trained to precisely identify noise events in the intracardiac electrogram of RM data.
Methods: We analyzed 21 918 RM data consisting of 12 925 and 1884 Medtronic and Boston Scientific data, respectively. Among these, 153 and 52 Medtronic and Boston Scientific data, respectively, were diagnosed as noise events by human analysis. In Medtronic, 306 events, including 153 noise events and randomly selected 153 out of 12 692 nonnoise events, were analyzed in a five-fold cross-validation with a convolutional neural network. The Boston Scientific data were analyzed similarly.
Results: The precision rate, recall rate, F1 score, accuracy rate, and the area under the curve were 85.8 ± 4.0%, 91.6 ± 6.7%, 88.4 ± 2.0%, 88.0 ± 2.0%, and 0.958 ± 0.021 in Medtronic and 88.4 ± 12.8%, 81.0 ± 9.3%, 84.1 ± 8.3%, 84.2 ± 8.3% and 0.928 ± 0.041 in Boston Scientific. Five-fold cross-validation with a weighted loss function could increase the recall rate.
Conclusions: AI can accurately detect noise events. AI analysis may be helpful for detecting lead failure events early and accurately. en-copyright= kn-copyright= en-aut-name=NishiiNobuhiro en-aut-sei=Nishii en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei=

core crystallization process in planetesimals en-subtitle= kn-subtitle= en-abstract= kn-abstract=In differentiated planetesimals, the liquid core starts to crystallize during secular cooling, followed by the separation of liquid–solid phases in the core. The wetting property between liquid and solid iron alloys determines whether the core melts are trapped in the solid core or they can separate from the solid core during core crystallization. In this study, we performed high-pressure experiments under the conditions of the interior of small bodies (0.5–3.0 GPa) to study the wetting property (dihedral angle) between solid Fe and liquid Fe-S as a function of pressure and duration. The measured dihedral angles are approximately constant after 2 h and decrease with increasing pressure. The dihedral angles range from 30° to 48°, which are below the percolation threshold of 60° at 0.5–3.0 GPa. The oxygen content in the melt decreases with increasing pressure and there are strong positive correlations between the S + O or O content and the dihedral angle. Therefore, the change in the dihedral angle is likely controlled by the O content of the Fe-S melt, and the dihedral angle tends to decrease with decreasing O content in the Fe-S melt. Consequently, the Fe-S melt can form interconnected networks in the solid core. In the obtained range of the dihedral angle, a certain amount of the Fe-S melt can stably coexist with solid Fe, which would correspond to the “trapped melt” in iron meteorites. Excess amounts of the melt would migrate from the solid core over a long period of core crystallization in planetesimals. en-copyright= kn-copyright= en-aut-name=MatsubaraShiori en-aut-sei=Matsubara en-aut-mei=Shiori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=YoshinoTakashi en-aut-sei=Yoshino en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UrakawaSatoru en-aut-sei=Urakawa en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YumitoriDaisuke en-aut-sei=Yumitori en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Earth Sciences, Graduate School of Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Earth Sciences, Graduate School of Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=4 en-affil=Department of Earth Sciences, Graduate School of Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Department of Earth Sciences, Graduate School of Science and Technology, 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=2024 dt-pub=20240325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Idiopathic ventricular tachycardia detected after coronavirus disease 2019 en-subtitle= kn-subtitle= en-abstract= kn-abstract=We present a 23-year-old woman with depression and long COVID in whom a diagnosis of idiopathic ventricular tachycardia (VT) was made.

Methods and results: We examined p16 and Rb expressions by immunohistochemistry (IHC) and the transcriptionally active HR-HPV infection by mRNA in-situ hybridisation (ISH) with histological review in 108 ECA cases. Thirteen adenocarcinomas of endometrial or equivocal origin (six endometrioid and seven serous carcinomas) were compared as the control group. HR-HPV was detected in 83 of 108 ECA cases (77%), including five HPV-associated adenocarcinomas in situ and 78 invasive HPV-associated adenocarcinomas. All 83 HPV-positive cases showed consistent morphology, p16 positivity and partial loss pattern of Rb. Among the 25 cases of HPV-independent adenocarcinoma, four (16%) were positive for p16, and of these four cases, three of 14 (21%) were gastric type adenocarcinomas and one of 10 (10%) was a clear cell type adenocarcinoma. All 25 HPV-independent adenocarcinomas showed preserved expression of Rb irrespective of the p16 status. Similarly, all 13 cases of the control group were negative for HR-HPV with preserved expression of Rb, even though six of 13 (46%) cases were positive for p16. Compared with p16 alone, the combination of p16 overexpression and Rb partial loss pattern showed equally excellent sensitivity (each 100%) and improved specificity (100 versus 73.6%) and positive predictive values (100 versus 89.2%) in the ECA and control groups. Furthermore, HR-HPV infection correlated with better prognosis among invasive ECAs.
Conclusions: The results suggest that the combined use of p16 and Rb IHC could be a reliable method to predict HR-HPV infection in primary ECAs and mimics. This finding may contribute to prognostic prediction and therapeutic strategy. en-copyright= kn-copyright= en-aut-name=YasutakeNobuko en-aut-sei=Yasutake en-aut-mei=Nobuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoHidetaka en-aut-sei=Yamamoto en-aut-mei=Hidetaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KugaRyosuke en-aut-sei=Kuga en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=JiromaruRina en-aut-sei=Jiromaru en-aut-mei=Rina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HongoTakahiro en-aut-sei=Hongo en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatayamaYoshihiro en-aut-sei=Katayama en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SonodaKenzo en-aut-sei=Sonoda en-aut-mei=Kenzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YahataHideaki en-aut-sei=Yahata en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KatoKiyoko en-aut-sei=Kato en-aut-mei=Kiyoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OdaYoshinao en-aut-sei=Oda en-aut-mei=Yoshinao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gynecology and Obstetrics, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Anatomic Pathology, Pathological Sciences, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=4 en-affil=Department of Otorhinolaryngology, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=5 en-affil=Department of Otorhinolaryngology, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=6 en-affil=Department of Gynecology and Obstetrics, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=7 en-affil=Department of Gynecology and Obstetrics, National Kyushu Cancer Center kn-affil= affil-num=8 en-affil=Department of Gynecology and Obstetrics, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=9 en-affil=Department of Gynecology and Obstetrics, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=10 en-affil=Department of Anatomic Pathology, Pathological Sciences, Graduate School of Medical Sciences, Kyushu University kn-affil= en-keyword=endocervical adenocarcinoma kn-keyword=endocervical adenocarcinoma en-keyword=human papillomavirus kn-keyword=human papillomavirus en-keyword=p16 kn-keyword=p16 en-keyword=Rb kn-keyword=Rb en-keyword=uterus kn-keyword=uterus END start-ver=1.4 cd-journal=joma no-vol=46 cd-vols= no-issue=5 article-no= start-page=1074 end-page=1082 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240307 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Combined simultaneous endoscopic endonasal and transcranial surgery using high‐definition three‐dimensional exoscope for malignant tumors of the anterior skull base en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Advanced surgical interventions are required to treat malignancies in the anterior skull base (ASB). This study investigates the utility of endoscopic endonasal and transcranial surgery (EETS) using a high-definition three-dimensional exoscope as an alternative to traditional microscopy.
Methods: Six patients with carcinomas of varying histopathologies underwent surgery employing the EETS maneuver, which synchronized three distinct surgical modalities: harvesting of the anterolateral thigh flap, initiation of the transnasal technique, and initiation of the transcranial procedure.
Results: The innovative strategy enabled successful tumor resection and skull base reconstruction without postoperative local neoplastic recurrence, cerebrospinal fluid leakage, or neurological deficits.
Conclusion: The integration of the exoscope and EETS is a novel therapeutic approach for ASB malignancies. This strategy demonstrates the potential of the exoscope in augmenting surgical visualization, enhancing ergonomics, and achieving seamless alignment of multiple surgical interventions.

Toll-like receptor ligands and SAA en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effect of persistent skin inflammation on extracutaneous organs and blood is not well studied. Patients with recessive dystrophic epidermolysis bullosa (RDEB), a severe form of the inherited blistering skin disorder, have widespread and persistent skin ulcers, and they develop various complications including anaemia, hyperglobulinaemia, hypoalbuminaemia and secondary amyloidosis. These complications are associated with the bioactivities of IL-6, and the development of secondary amyloidosis requires the persistent elevation of serum amyloid A (SAA) level. We found that patients with RDEB had significantly higher serum levels of IL-6 and SAA compared to healthy volunteers and patients with psoriasis or atopic dermatitis. Both IL-6 and SAA were highly expressed in epidermal keratinocytes and dermal fibroblasts of the skin ulcer lesions. Keratinocytes and fibroblasts surrounding the ulcer lesions are continuously exposed to Toll-like receptor (TLR) ligands, pathogen-associated and damage-associated molecular pattern molecules. In vitro, TLR ligands induced IL-6 expression via NF-κB in normal human epidermal keratinocytes (NHEKs) and dermal fibroblasts (NHDFs). SAA further induced the expression of IL-6 via TLR1/2 and NF-κB in NHEKs and NHDFs. The limitation of this study is that NHEKs and NHDFs were not derived from RDEB patients. These observations suggest that TLR-mediated persistent skin inflammation might increase the risk of IL-6-related systemic complications, including RDEB. en-copyright= kn-copyright= en-aut-name=KawakamiYoshio en-aut-sei=Kawakami en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KajitaAi en-aut-sei=Kajita en-aut-mei=Ai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HasuiKen‐Ichi en-aut-sei=Hasui en-aut-mei=Ken‐Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsudaYoshihiro en-aut-sei=Matsuda en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwatsukiKeiji en-aut-sei=Iwatsuki en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MorizaneShin en-aut-sei=Morizane en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Dermatology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Dermatology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Dermatology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Dermatology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Dermatology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Dermatology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=epidermolysis bullosa kn-keyword=epidermolysis bullosa en-keyword=fibroblasts kn-keyword=fibroblasts en-keyword=IL-6 kn-keyword=IL-6 en-keyword=keratinocytes kn-keyword=keratinocytes en-keyword=serum amyloid A kn-keyword=serum amyloid A END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=3 article-no= start-page=e8643 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240311 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Vogt-Koyanagi-Harada disease in pregnancy: Case report and review of 32 patients in the literature en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 30-year-old woman in 31 weeks of pregnancy with metamorphopsia and headache was diagnosed Vogt-Koyanagi-Harada disease.

We previously reported a multi-center, retrospective study in which the incidence of reflux esophagitis (RE) (Los Angeles Classification ≥Grade B [LA-B]) 1 year after surgery was 6.0%. There have been many reports, but all of them were retrospective. Thus, a multi-center, prospective study was conducted.
Methods: Laparoscopic PG + DFT was performed for cT1N0 upper gastric cancer patients. The primary endpoint was the incidence of RE (≥LA-B) 1 year after surgery. The planned sample size was 40, based on an estimated incidence of 6.0% and an upper threshold of 20%.
Results: Forty patients were recruited, and 39, excluding one with conversion to total gastrectomy, received protocol treatment. Anastomotic leakage (Clavien–Dindo ≥Grade III) was observed in one patient (2.6%). In 38 patients, excluding one case of postoperative mortality, RE (≥LA-B) was observed in two patients (5.3%) 1 year after surgery, and the upper limit of the 95% confidence interval was 17.3%, lower than the 20% threshold. Anastomotic stricture requiring dilatation was observed in two patients (5.3%). One year after surgery, body weight change was 88.9 ± 7.0%, and PNI <40 and CONUT ≥5, indicating malnutrition, were observed in only one patient (2.6%) each. In the quality of life survey using the PGSAS-45 questionnaire, the esophageal reflux subscale score was 1.4 ± 0.6, significantly better than the public data (2.0 ± 1.0; p = 0.001).
Conclusion: Laparoscopic DFT showed anti-reflux efficacy. Taken together with the acceptable incidence of anastomotic stricture, DFT can be an option for reconstruction procedure after PG. en-copyright= kn-copyright= en-aut-name=KurodaShinji en-aut-sei=Kuroda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshidaMichihiro en-aut-sei=Ishida en-aut-mei=Michihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ChodaYasuhiro en-aut-sei=Choda en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MuraokaAtsushi en-aut-sei=Muraoka en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HatoShinji en-aut-sei=Hato en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=TanakaNorimitsu en-aut-sei=Tanaka en-aut-mei=Norimitsu 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=KakiuchiYoshihiko en-aut-sei=Kakiuchi en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=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 Surgery, Hiroshima City Hiroshima Citizens Hospital, Hiroshima kn-affil= affil-num=3 en-affil=Department of Surgery, Hiroshima City Hiroshima Citizens Hospital, Hiroshima kn-affil= affil-num=4 en-affil=Department of Surgery, Kagawa Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Surgery, Shikoku Cancer Center kn-affil= affil-num=6 en-affil=Department of Surgery, Shikoku Cancer Center kn-affil= affil-num=7 en-affil=Department of Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=8 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital 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 Surgery, Tsuyama Chuo Hospital 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=anti-reflux surgery kn-keyword=anti-reflux surgery en-keyword=double-flap technique kn-keyword=double-flap technique en-keyword=gastric cancer kn-keyword=gastric cancer en-keyword=Kamikawa procedure kn-keyword=Kamikawa procedure en-keyword=proximal gastrectomy kn-keyword=proximal gastrectomy END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=2 article-no= start-page=102 end-page=109 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240221 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Treatment interruption in hypertensive patients during the COVID-19 pandemic: An interrupted time series analysis using prescription data in Okayama, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The COVID- 19 pandemic has impacted healthcare behaviors, leading to fewer pediatric visits in Japan and potentially fewer visits by adult patients. However, existing Japanese studies on treatment interruptions have generally relied on questionnaire- based methods. In this study, we assessed the impact of the pandemic on antihypertensive treatment interruption using real- world prescription data.
Methods: We conducted an interrupted time series analysis using the National Health Insurance Database in Okayama Prefecture, Japan. Participants included individuals aged 40-69 years with at least one antihypertensive prescription between 2018 and 2020. Treatment interruption was defined as a 3- month or longer gap in prescriptions after medication depletion. We used segmented Poisson regression with models unadjusted and adjusted for seasonality and over- dispersion to assess monthly treatment interruptions before and after Japan's April 2020 emergency.
Results: During the study period, 23.0% of 55,431 participants experienced treatment interruptions. Cyclical fluctuations in interruptions were observed. The crude analysis indicated a 1.2 - fold increase in treatment interruptions following the pandemic; however, the adjusted models showed no significant changes. Even among higher- risk groups, such as women, younger adults, and those with shorter prescriptions, no significant alterations were observed.
Conclusion: We found no significant impact of the COVID- 19 pandemic on antihypertensive treatment interruption in Okayama Prefecture. The less severe outbreak in the area or increased use of telemedicine and extended prescriptions may have contributed to treatment continuity. Further research is needed using a more stable and comprehensive database, broader regional data, and detailed prescription records to validate and extend our findings. en-copyright= kn-copyright= en-aut-name=NakamuraNaoko en-aut-sei=Nakamura en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HayaseShunsaku en-aut-sei=Hayase en-aut-mei=Shunsaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Academic Affairs Division, Okayama University kn-affil= affil-num=5 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=antihypertensive agents kn-keyword=antihypertensive agents en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=health behavior kn-keyword=health behavior en-keyword=interrupted time series analysis kn-keyword=interrupted time series analysis en-keyword=prescription drugs kn-keyword=prescription drugs en-keyword=treatment interruption kn-keyword=treatment interruption END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=2 article-no= start-page=e8534 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240219 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Penile cavernosal abscess after urethral injury en-subtitle= kn-subtitle= en-abstract= kn-abstract=We present a patient catheterized for prostatic lesions who developed sepsis of urinary origin with a penile cavernosal abscess due to urethral injury caused by catheter ballooning.

As in many other cancer types, cancer stem cells (CSCs) have been identified in MPNSTs, and they are considered the cause of treatment resistance, recurrence, and metastasis. As an element defining the cancer stemness of MPNSTs, we previously reported a molecular mechanism by which exogenous adrenaline activates a core cancer stemness factor, YAP/TAZ, through β2 adrenoceptor (ADRB2). In this study, we found that MPNST cells express catecholamine synthases and that these enzymes are essential for maintaining cancer stemness, such as the ability to self-renew and maintain an undifferentiated state. Through gene knockdown and inhibition of these enzymes, we confirmed that catecholamines are indeed synthesized in MPNST cells. The results confirmed that catecholamine synthase knockdown in MPNST cells reduces the activity of YAP/TAZ. These data suggest that a mechanism of YAP/TAZ activation by de novo synthesized adrenaline, as well as exogenous adrenaline, may exist in the maintenance of cancer stemness of MPNST cells. This mechanism not only helps to understand the pathology of MPNST, but could also contribute to the development of therapeutic strategies for MPNST. en-copyright= kn-copyright= en-aut-name=KatayamaHaruyoshi en-aut-sei=Katayama en-aut-mei=Haruyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujimuraAtsushi en-aut-sei=Fujimura en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HuangRongsheng en-aut-sei=Huang en-aut-mei=Rongsheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OtaniYusuke en-aut-sei=Otani en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ItanoTakuto en-aut-sei=Itano en-aut-mei=Takuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiwaraTomohiro en-aut-sei=Fujiwara en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KunisadaToshiyuki en-aut-sei=Kunisada en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji 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 Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Trauma Orthopedics, The Second Hospital of Dalian Medical University kn-affil= affil-num=4 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=5 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=benserazide kn-keyword=benserazide en-keyword=cancer stem cell kn-keyword=cancer stem cell en-keyword=catecholamine synthase kn-keyword=catecholamine synthase en-keyword=malignant peripheral nerve sheath tumor kn-keyword=malignant peripheral nerve sheath tumor en-keyword=Schwann cell kn-keyword=Schwann cell en-keyword=vesicular monoamine transporter kn-keyword=vesicular monoamine transporter END start-ver=1.4 cd-journal=joma no-vol=115 cd-vols= no-issue=4 article-no= start-page=1317 end-page=1332 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240126 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Antitumor activity of α-pinene in T-cell tumors en-subtitle= kn-subtitle= en-abstract= kn-abstract=T-cell acute leukemia and lymphoma have a poor prognosis. Although new therapeu-tic agents have been developed, their therapeutic effects are suboptimal. α- Pinene, a monoterpene compound, has an antitumor effect on solid tumors; however, few comprehensive investigations have been conducted on its impact on hematologic ma-lignancies. This report provides a comprehensive analysis of the potential benefits of using α- pinene as an antitumor agent for the treatment of T-cell tumors. We found that α- pinene inhibited the proliferation of hematologic malignancies, especially in T- cell tumor cell lines EL-4 and Molt-4, induced mitochondrial dysfunction and re-active oxygen species accumulation, and inhibited NF-κB p65 translocation into the nucleus, leading to robust apoptosis in EL-4 cells. Collectively, these findings suggest that α- pinene has potential as a therapeutic agent for T-cell malignancies, and further investigation is warranted. en-copyright= kn-copyright=

Methods: The study included 155 patients diagnosed with MMPRTs who underwent transtibial pullout repair. Meniscal healing status was evaluated on second-look arthroscopy using a previously reported meniscus healing score. Patients were divided into two groups based on this score: the high healing score (group HH, healing score ≥ 8 points) and suboptimal healing score (group SO, healing score ≤ 6 points) groups. Computed tomography scans were performed on patients 1 week postsurgery. ICNW and OW widths were measured and relatively evaluated based on their ratio to the intercondylar distance (ICD), represented as the ICNW/ICD ratio (%) and OW/ICD ratio (%), respectively. Patient-reported outcomes were assessed preoperatively and on second-look arthroscopy using the Knee injury and Osteoarthritis Outcome Score (KOOS) and visual analogue scale (VAS).
Results: There were no significant demographic differences between the SO and HH group (n = 35 and 120 patients, respectively). Regarding radiographic measurements, significant differences were observed in the ICNW/ICD ratio (group SO, 24.2%; group HH, 25.2%; p = 0.024), OW (group SO, 2.6 mm; group HH, 2.0 mm; p < 0.001), and OW/ICD ratio (group SO, 3.5%; group HH, 2.7%; p < 0.001). Both groups had similar preoperative clinical scores, but postoperative clinical scores, including KOOS-activities of daily living (group SO, 83.4; group HH, 88.7; p = 0.035) and VAS (group SO, 19.1; group HH, 11.3; p = 0.005), were significantly better in group HH.
Conclusion: The study suggests that ICNW and OW may play a crucial role in MMPRT healing following arthroscopic pullout repair, as evidenced by the worse clinical outcomes associated with a narrower ICNW and wider OW. These findings highlight the potential significance of ICNW and OW assessments when evaluating meniscal repair indications. 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=YokoyamaYusuke en-aut-sei=Yokoyama en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=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=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, 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=intercondylar notch width kn-keyword=intercondylar notch width en-keyword=intercondylar osteophyte kn-keyword=intercondylar osteophyte en-keyword=medial meniscus posterior root tear kn-keyword=medial meniscus posterior root tear en-keyword=transtibial pullout repair kn-keyword=transtibial pullout repair END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e12636 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231229 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Trends in childhood obesity in Japan: A nationwide observational study from 2012 to 2021 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The persistent ascension of childhood obesity on a global scale constitutes a significant quandary. The prevalence of childhood obesity in Japan peaked in the early 2000s and has been reported to have declined since then, but recent data and its trend including the novel coronavirus disease 2019 (COVID-19) pandemic era are not available. Moreover, there is a dearth of studies examining the correlation between the trend in childhood obesity and exercise habits over the past decade. This study aims to examine the changes in the prevalence of obesity, physical fitness, and exercise habits over the past 10 years in Japanese children. We investigated the prevalence of childhood obesity in Japan, using the School Health Statistics Survey data from 2012 to 2021. The dataset has a sample size representative of children nationwide and includes variables for obesity, such as height, weight, and age. Data were classified into groups by sex and age (6–8, 9–11, and 12–14 years age). Children weighing 20% or more of the standard body weight are classified as obese. The annual percentage changes and average annual percentage changes were estimated using the joinpoint regression model. We also examined the trends in the physical fitness test score and exercise time. Average annual percentage changes of boys increased, especially in the 6- to 8-year age group (3.4%–4.6%). For girls, average annual percentage changes had increased in 6- to 8-year (2.5%–4.0%) and 9- to 11-year (0.9%–2.2%) age groups. Since the late 2010s, significantly increasing annual percentage changes were observed in 12- to 14-year age boys (6.7%–8.9%) and girls of many age groups (2.6%–8.6%). The physical fitness test score and exercise time showed decreasing trends since the late 2010s. Childhood obesity may have generally risen in Japan, in the last decade. Encouraging healthy eating and physical activity through school policies and curricula is necessary. en-copyright= kn-copyright= en-aut-name=FujiwaraShintaro en-aut-sei=Fujiwara en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=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=HasegawaKosei en-aut-sei=Hasegawa en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Department of Pediatrics, NHO Okayama Medical Center kn-affil= affil-num=2 en-affil=Department of Medicine, Icahn School of Medicine at Mount Sinai, Mount Sinai Beth Israel 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 Pediatrics, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=childhood obesity kn-keyword=childhood obesity en-keyword=epidemiology kn-keyword=epidemiology en-keyword=joinpoint regression analysis kn-keyword=joinpoint regression analysis en-keyword=paediatrics kn-keyword=paediatrics en-keyword=trend analysis kn-keyword=trend analysis END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=1 article-no= start-page=143 end-page=150 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=Weight loss enhances meniscal healing following transtibial pullout repair for medial meniscus posterior root tears en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: This study investigated the impact of weight change on the success of transtibial pullout repair for medial meniscus (MM) posterior root tears (MMPRTs).
Methods: The study included 129 patients diagnosed with MMPRTs who had undergone transtibial pullout repair. The patients were screened between July 2018 and November 2021. Patient-reported outcomes were assessed preoperatively and at 12 months postoperatively using the Knee injury and Osteoarthritis Outcome Score (KOOS). MM extrusion (MME) and ΔMME (postoperative MME – preoperative MME) were calculated preoperatively and at 12 months postoperatively using magnetic resonance imaging.
Results: Patients were divided into weight loss (body mass index [BMI] decrease of at least 0.5 kg/m2 after primary repair; n = 63) and weight gain (BMI increase of at least 0.5 kg/m2; n = 66) groups. Both groups had similar demographic variables and preoperative clinical scores; patient-reported outcomes significantly improved postoperatively. The weight loss group had significantly greater improvement in KOOS–quality of life (weight loss, 29.4 ± 23.7; weight gain, 23.9 ± 27.6; p = 0.034), lower postoperative MME (weight loss, 3.9 ± 1.7 mm; weight gain, 4.2 ± 1.2 mm; p = 0.043) and lower ΔMME (weight loss, 0.8 ± 0.8 mm; weight gain, 1.2 ± 0.9 mm; p = 0.002) than the weight gain group. Total arthroscopic healing scores (weight loss, 7.6 ± 1.0; weight gain, 7.2 ± 1.5; p = 0.048) and associated subscales, including anteroposterior bridging tissue width (weight loss, 4.0 ± 0.0; weight gain, 3.8 ± 0.7; p = 0.004) and MM posterior root stability (weight loss, 2.6 ± 0.7; weight gain, 2.4 ± 0.7; p = 0.041), significantly differed between the groups.
Conclusions: Weight loss was associated with better meniscal healing and less MME progression after MMPRT repair, highlighting the significance of weight management in individuals undergoing meniscal surgery. These findings provide valuable insights into the clinical significance of weight loss in the success of transtibial pullout repair for MMPRTs. 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=YokoyamaYusuke en-aut-sei=Yokoyama en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=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 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=clinical outcomes kn-keyword=clinical outcomes en-keyword=medial meniscus posterior root tears kn-keyword=medial meniscus posterior root tears en-keyword=transtibial pullout repair kn-keyword=transtibial pullout repair en-keyword=weight change kn-keyword=weight change END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=1 article-no= start-page=e914 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical parameter-guided initial resuscitation in adult patients with septic shock: A systematic review and network meta-analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim: To identify the most useful tissue perfusion parameter for initial resuscitation in sepsis/septic shock adults using a network meta-analysis.
Methods: We searched major databases until December 2022 for randomized trials comparing four tissue perfusion parameters or against usual care. The primary outcome was short-term mortality up to 90 days. The Confidence in Network Meta-Analysis web application was used to assess the quality of evidence.
Results: Seventeen trials were identified. Lactate-guided therapy (risk ratios, 0.59; 95% confidence intervals [0.45–0.76]; high certainty) and capillary refill time-guided therapy (risk ratios, 0.53; 95% confidence intervals [0.33–0.86]; high certainty) were significantly associated with lower short-term mortality compared with usual care, whereas central venous oxygen saturation-guided therapy (risk ratio, 1.50; 95% confidence intervals [1.16–1.94]; moderate certainty) increased the risk of short-term mortality compared with lactate-guided therapy.
Conclusions: Lactate or capillary refill time-guided initial resuscitation for sepsis/septic shock patients may decrease short-term mortality. More research is essential to personalize and optimize treatment strategies for septic shock resuscitation. en-copyright= kn-copyright= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuribaraTomoki en-aut-sei=Kuribara en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamadaKohei en-aut-sei=Yamada en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatoTakehito en-aut-sei=Sato en-aut-mei=Takehito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobaShigeru en-aut-sei=Koba en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TetsuharaKenichi en-aut-sei=Tetsuhara en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KashiuraMasahiro en-aut-sei=Kashiura en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SakurayaMasaaki en-aut-sei=Sakuraya en-aut-mei=Masaaki 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=School of Nursing, Sapporo City University kn-affil= affil-num=3 en-affil=Department of Traumatology and Critical Care Medicine, National Defense Medical College Hospital kn-affil= affil-num=4 en-affil=Department of Anesthesiology, Nagoya University Hospital kn-affil= affil-num=5 en-affil=Department of Critical Care Medicine, Nerima Hikarigaoka Hospital kn-affil= affil-num=6 en-affil=Department of Critical Care Medicine, Fukuoka Children's Hospital kn-affil= affil-num=7 en-affil=Department of Emergency and Critical Care Medicine, Saitama Medical Center, Jichi Medical University kn-affil= affil-num=8 en-affil=Department of Emergency and Intensive Care Medicine, JA Hiroshima General Hospital kn-affil= en-keyword=capillary refill timecarbon dioxide gapcentral venous oxygen saturationlactatenetwork meta-analysissepsisseptic shock kn-keyword=capillary refill timecarbon dioxide gapcentral venous oxygen saturationlactatenetwork meta-analysissepsisseptic shock END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=1 article-no= start-page=e13009 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical significance of gastrointestinal bleeding history in patients who undergo left atrial appendage closure en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Aim: Anticoagulant users with nonvalvular atrial fibrillation (NVAF) sometimes suffer from gastrointestinal bleeding (GIB) and have difficulty continuing the medication. Left atrial appendage closure (LAAC) has been developed for such situations. We aimed to clarify the clinical significance of a history of GIB in comparison to other factors in patients who had undergone LAAC.
Methods: From October 2019 to September 2023, patients with NVAF who underwent LAAC at our hospital were enrolled. We investigated the percentage of patients with a history of GIB who underwent LAAC and compared the incidence of post-LAAC bleeding in these patients compared to those with other factors.
Results: A total of 45 patients were included. There were 19 patients (42%) with a history of GIB who underwent LAAC. In a Kaplan–Meier analysis, the cumulative incidence of bleeding complications after LAAC was significantly higher in patients with a history of GIB in comparison to patients with other factors. There were eight cases of post-LAAC bleeding in total, and seven cases had GIB.
Conclusions: We need to recognize that GIB is a significant complication in patients who undergo LAAC. The management of GIB by gastroenterologists is essential to the success of LAAC. en-copyright= kn-copyright= en-aut-name=KikuchiTatsuya en-aut-sei=Kikuchi en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei=

kn-title=Radiological characteristics of skeletal growth in neonates and infants with achondroplasia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Achondroplasia (ACH) is the most common form of skeletal dysplasia characterized by a rhizomelic short stature. Radiological skeletal findings in pediatric and adult patients with ACH include short long bones, a relatively longer fibula compared to the tibia, a narrow lumbar interpedicular distance, and a hypoplastic iliac wing. Nonetheless, the characteristics of skeletal growth during the neonatal and infantile periods have scarcely been explored. Therefore, this retrospective study aimed to analyze the radiological skeletal growth during the neonatal and infantile periods in 41 Japanese patients with genetically confirmed ACH. The length of long bones in the upper and lower limbs and the lumbar interpedicular distances at L1 and L4 were measured. These parameters showed significant positive correlations with age. The upper segment-to-lower segment ratio in the lower limbs resembled the data of healthy controls from previous reports. The L1/L4 and fibula/tibia ratios increased with age, suggesting that some representative skeletal phenotypes of ACH were less distinct during the neonatal and infantile periods. In conclusion, for the first time, this study radiologically characterized skeletal growth during the neonatal and infantile periods of patients with genetically confirmed ACH. en-copyright= kn-copyright= en-aut-name=MiyaharaDaisuke en-aut-sei=Miyahara en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HasegawaKosei en-aut-sei=Hasegawa en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AgoYuko en-aut-sei=Ago en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FutagawaNatsuko en-aut-sei=Futagawa en-aut-mei=Natsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyaharaHiroyuki en-aut-sei=Miyahara en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HiguchiYousuke en-aut-sei=Higuchi en-aut-mei=Yousuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamadaKazuki en-aut-sei=Yamada en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TetsunagaTomonori en-aut-sei=Tetsunaga en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoriwakeTadashi en-aut-sei=Moriwake en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaHiroyuki en-aut-sei=Tanaka en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Orthopedics, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Orthopedics, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Pediatrics, Iwakuni Clinical Center, National Hospital Organization kn-affil= affil-num=10 en-affil=Department of Pediatrics, Okayama Saiseikai General Hospital kn-affil= affil-num=11 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=bone development kn-keyword=bone development en-keyword=dwarfism kn-keyword=dwarfism en-keyword=growth kn-keyword=growth en-keyword=infant kn-keyword=infant en-keyword=radiography kn-keyword=radiography 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=20231217 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Significant delayed conduction and characteristic ventricular tachycardias in patients with cardiac sarcoidosis and electrical storm en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Electrical storm (ES) of ventricular tachyarrhythmias (VTAs) is an important cause of sudden death in patients with cardiac sarcoidosis (CS). VTAs in CS are associated with myocardial scarring and inflammation. However, little is known about the risk factors of ES in patients with CS and VTAs. The objective of this study is to clarify the characteristics and risk factors for the development of ES in patients with CS.
Methods: The study population included consecutive 52 patients with CS and sustained VTA. Twenty-five out of 52 patients experienced ES. We evaluated clinical characteristics, imaging modalities, and electrocardiogram (ECG) parameters to determine the risk factors associated with ES.
Results: Half of the patients experienced VTAs as the initial symptom of sarcoidosis, and eight patients had ES as the initial VTA episode. There were no differences in cardiac imaging abnormalities between patients with and without ES. Among ECG markers, significant QRS fragmentation (odds ratio [OR]: 7.9, p = .01) and epsilon waves (OR: 12.24, p = .02) were associated with ES. Among the ventricular tachycardia (VT) characteristics, multiple morphologies of monomorphic VTs (OR: 10.9, p < .01), short VT cycle lengths (OR: 12.5, p < .01), and polymorphic VT (OR: 13.5, p < .01) were associated with ES. Bidirectional VTs were detected in 10 patients with ES and one patient without ES. Immunosuppressive therapy relieved ES in some patients.
Conclusions: ES was common in patients with CS and VTAs. Significant depolarization abnormalities that appeared as QRS fragmentation, epsilon waves, and specific VT characteristics were associated with ES.

We aimed to examine the association of changes in skeletal muscle mass and quality during the waiting time, as well as preoperative skeletal muscle mass and quality, with outcomes of LT.
Methods: This study included individuals who underwent LT from brain-dead donors. Skeletal muscle mass (cm2/m2) and quality (mean Hounsfield units [HU]) of the erector spinae muscle at the 12th thoracic level were evaluated using computed tomography. Preoperative skeletal muscle mass and quality, and their changes during the waiting time were calculated. We evaluated the associations among mechanical ventilation (MV) duration, intensive care unit (ICU) length of stay (LOS), hospital LOS, 6-minute walk distance at discharge, and 5-year survival after LT.
Results: This study included 98 patients. The median waiting time was 594.5 days (interquartile range [IQR], 355.0–913.0). The median changes in skeletal muscle mass and quality were −4.4% (IQR, −13.3–3.1) and −2.9% (IQR, −16.0–4.1), respectively. Severe low skeletal muscle mass at LT was associated with prolonged ICU LOS (B = 8.46, 95% confidence interval [CI]: .51–16.42) and hospital LOS (B = 36.00, 95% CI: 3.23–68.78). Pronounced decrease in skeletal muscle mass during the waiting time was associated with prolonged MV duration (B = 7.85, 95% CI: .89–14.81) and ICU LOS (B = 7.97, 95% CI: .83–15.10).
Conclusion: Maintaining or increasing skeletal muscle mass during the waiting time would be beneficial to improve the short-term outcomes of LT. en-copyright= kn-copyright= en-aut-name=HagiyamaAkikazu en-aut-sei=Hagiyama en-aut-mei=Akikazu 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=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin 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=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 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=8 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=9 ORCID= affil-num=1 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University Hospital kn-affil= affil-num=7 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University Hospital kn-affil= affil-num=8 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=computed tomography kn-keyword=computed tomography en-keyword=lung transplantation kn-keyword=lung transplantation en-keyword=prognosis kn-keyword=prognosis en-keyword=skeletal muscle kn-keyword=skeletal muscle en-keyword=waiting time kn-keyword=waiting time END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=1 article-no= start-page=e15696 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231115 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Adverse reactions in young children receiving the coronavirus disease 2019 vaccine en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: We sought to investigate the occurrence of adverse reactions in Japanese children aged 6 months to 4 years who received the BNT162b2 coronavirus disease 2019 (COVID-19) vaccine, to examine parental considerations, and to evaluate potential risk factors associated with post-vaccination fever.
Methods: This cross-sectional survey study targeted 1617 children aged 6 months to 4 years who received their primary doses of BNT162b2 from November 10, 2022, to April 30, 2023, in Okayama Prefecture. We surveyed the occurrence of local and systemic reactions within 1 week after vaccination, and described the incidence proportions of adverse reactions for 515 participants overall and by age group. The study also examined the impact of previous COVID-19 infection and co-administration of the seasonal influenza vaccine on post-vaccination fever. A survey also assessed parents' reasons for vaccinating their children and the sources of information they used.
Results: Adverse reactions were infrequent (5.2%, with fever ≥37.5°C; no cases exceeded 39°C) and did not increase with vaccine doses administered. The risk of post-vaccination fever was not statistically associated with a history of COVID-19—the adjusted risk ratio (aRR) was 0.99, and the 95% confidence interval (CI) was 0.41–2.39—but was associated with co-administration of the seasonal influenza vaccine (aRR 3.24, 95% CI 1.14–9.18). Parental decisions regarding vaccination were influenced by official government guidelines and primary care physicians' opinion.
Conclusion: This study provides valuable insight into the safety profile of the BNT162b2 vaccine in Japanese children aged 6 months to 4 years. Further research involving larger cohorts and appropriate control groups is needed. en-copyright= kn-copyright= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimizuJunya en-aut-sei=Shimizu en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YokoyamaYuji en-aut-sei=Yokoyama en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= affil-num=1 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pediatrics, National Hospital Organization, Okayama Medical Center kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama Aiiku Clinic kn-affil= affil-num=4 en-affil=Department of Pediatrics, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=adverse reaction kn-keyword=adverse reaction en-keyword=BNT162b2 kn-keyword=BNT162b2 en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=vaccine kn-keyword=vaccine en-keyword=young children kn-keyword=young children END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e202300835 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231113 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electrochemical Coupling Reactions Using Non‐Transition Metal Mediators: Recent Advances en-subtitle= kn-subtitle= en-abstract= kn-abstract=Indirect electrolysis method using appropriate mediators enables numerous chemical reactions.

Recognition of viral dsRNA by host pattern recognition receptors – such as retinoic acid-induced gene-I (RIG-I)-like receptors and Toll-like receptor 3 – triggers the production of interferon (IFN)-β via the activation of IFN regulatory factor (IRF)-3. It has been proposed that, during the replication of viral genomes, each of RIG-I and melanoma differentiation-associated gene 5 (MDA5) form homodimers for the efficient activation of a downstream signalling pathway in host cells. We previously reported that, in the non-neoplastic human hepatocyte line PH5CH8, the RdRp NS5B derived from hepatitis C virus (HCV) could induce IFN-β expression by its RdRp activity without the actual replication of viral genomes. However, the exact mechanism by which HCV NS5B produced IFN-β remained unknown. In the present study, we first showed that NS5B derived from another Flaviviridae family member, GB virus B (GBV-B), also possessed the ability to induce IFN-β in PH5CH8 cells. Similarly, HCV NS5B, but not its G317V mutant, which lacks RdRp activity, induced the dimerization of MDA5 and subsequently the activation of IRF-3. Interestingly, immunofluorescence analysis showed that HCV NS5B produced dsRNA. Like HCV NS5B, GBV-B NS5B also triggered the production of dsRNA and subsequently the dimerization of MDA5. Taken together, our results show that HCV NS5B triggers an MDA5-mediated innate immune response by producing dsRNA without the replication of viral genomes in human hepatocytes. en-copyright= kn-copyright= en-aut-name=DansakoHiromichi en-aut-sei=Dansako en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkedaMasanori en-aut-sei=Ikeda en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AriumiYasuo en-aut-sei=Ariumi en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TogashiYosuke en-aut-sei=Togashi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatoNobuyuki en-aut-sei=Kato en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Division of Biological Information Technology, Joint Research Center for Human Retrovirus Infection, Kagoshima University kn-affil= affil-num=3 en-affil=Management Department of Biosafety, Laboratory Animal, and Pathogen Bank, National Institute of Infectious Diseases kn-affil= affil-num=4 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=double-stranded RNA kn-keyword=double-stranded RNA en-keyword=hepatitis C virus kn-keyword=hepatitis C virus en-keyword=innate immunity kn-keyword=innate immunity en-keyword=RIG-I-like receptor kn-keyword=RIG-I-like receptor en-keyword=RNA virus kn-keyword=RNA virus END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=7 article-no= start-page=1190 end-page=1202 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220421 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reduction in the magnitude of serum potassium elevation in combination therapy with esaxerenone (CS‐3150) and sodium–glucose cotransporter 2 inhibitor in patients with diabetic kidney disease: Subanalysis of two phase III studies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims/Introduction: We evaluated the effect of co-administration of esaxerenone and a sodium–glucose cotransporter 2 (SGLT2) inhibitor on the magnitude of serum potassium elevation in Japanese patients with diabetic kidney disease.
Materials and Methods: We carried out a prespecified subanalysis of data from two phase III studies: a multicenter, randomized, double-blind, placebo-controlled trial in patients with type 2 diabetes and microalbuminuria (J308); and a multicenter, single-arm, open-label trial in patients with type 2 diabetes and macroalbuminuria (J309). Changes in serum potassium levels during the studies and other measures were evaluated according to SGLT2 inhibitor use.
Results: In both studies, time-course changes in serum potassium levels, and incidence rates of serum potassium elevation were lower in patients with co-administration of SGLT2 inhibitor in both the placebo and esaxerenone groups than those without the inhibitor. In contrast, time-course changes and mean percentage changes from baseline in urinary albumin-to-creatinine ratio, the proportion of patients with albuminuria remission and time-course changes in blood pressure did not change with or without SGLT2 inhibitor, whereas the albumin-to-creatinine ratio and blood pressure were reduced with esaxerenone. The blood glucose-lowering effect of SGLT2 inhibitor was not affected by esaxerenone.
Conclusions: In Japanese patients with type 2 diabetes and albuminuria treated with esaxerenone, concomitant use of SGLT2 inhibitor reduced the magnitude of serum potassium elevation without any change of its antihypertensive and albuminuria-suppressing effects. Co-administration of esaxerenone and SGLT2 inhibitor might be a beneficial treatment option for patients with diabetic kidney disease. en-copyright= kn-copyright= en-aut-name=ShikataKenichi en-aut-sei=Shikata en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ItoSadayoshi en-aut-sei=Ito en-aut-mei=Sadayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KashiharaNaoki en-aut-sei=Kashihara en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NangakuMasaomi en-aut-sei=Nangaku en-aut-mei=Masaomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WadaTakashi en-aut-sei=Wada en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkudaYasuyuki en-aut-sei=Okuda en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SawanoboriTomoko en-aut-sei=Sawanobori en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugimotoKotaro en-aut-sei=Sugimoto en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Division of Nephrology, Endocrinology and Vascular Medicine, Department of Medicine, Tohoku University School of Medicine kn-affil= affil-num=3 en-affil=Department of Nephrology and Hypertension, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Division of Nephrology and Endocrinology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=5 en-affil=Department of Nephrology and Laboratory Medicine, Kanazawa University kn-affil= affil-num=6 en-affil=Department of Nephrology and Laboratory Medicine, Kanazawa University kn-affil= affil-num=7 en-affil=Clinical Development Department, Daiichi Sankyo Co., Ltd. kn-affil= affil-num=8 en-affil=Primary Medical Science Department, Daiichi Sankyo Co., Ltd. kn-affil= en-keyword=Esaxerenone kn-keyword=Esaxerenone en-keyword=Potassium kn-keyword=Potassium en-keyword=Sodium-glucose transporter 2 inhibitor kn-keyword=Sodium-glucose transporter 2 inhibitor END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=3 article-no= start-page=e12286 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230912 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of malnutrition on prognosis in patients with pulmonary arterial hypertension en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pulmonary arterial hypertension is a life-threatening disease that coexists with right heart failure. We evaluated the relationship between malnutrition and prognosis in patients with pulmonary arterial hypertension, as malnutrition is known as a prognosis determinant in chronic heart failure. We retrospectively reviewed data of patients with pulmonary arterial hypertension before treatment. The Geriatric Nutritional Risk Index, Prognostic Nutritional Index, and Controlling Nutritional Status scores on the day of diagnosis were calculated to assess the nutritional status. Clinical endpoints were defined as composite outcomes of all-cause death or lung transplantation. Eighty patients were enrolled (mean age, 50 years; 23 men). The mean pulmonary arterial pressure was 47 ± 19 mmHg, Geriatric Nutritional Risk Index was 99.9 ± 12.0, and Prognostic Nutritional Index was 46.3 ± 10.0. The median Controlling Nutritional Status score was 2 (1–4). During the median 5.5-year follow-up period, 28 composite events occurred. Kaplan-Meier analysis demonstrated significant differences in the incidence of clinical endpoints between groups divided by each median Geriatric Nutritional Risk Index, Prognostic Nutritional Index, and Controlling Nutritional Status score (p = 0.007, 0.039, and 0.010, respectively). In multivariate Cox regression analysis, clinical endpoints were significantly associated with Geriatric Nutritional Risk Index (hazard ratio: 0.953, 95% confidence interval: 0.918–0.990), Prognostic Nutritional Index (hazard ratio: 0.942, 95% confidence interval: 0.892–0.996), and Controlling Nutritional Status score (hazard ratio: 1.230, 95% confidence interval: 1.056–1.433) after adjustment for factors associated in univariate Cox regression analysis. Malnutrition at diagnosis is a useful prognostic predictor for patients with pulmonary arterial hypertension. en-copyright= kn-copyright= en-aut-name=NakashimaMitsutaka en-aut-sei=Nakashima en-aut-mei=Mitsutaka 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=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=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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= en-keyword=Controlling Nutritional Status score kn-keyword=Controlling Nutritional Status score en-keyword=Geriatric Nutritional Risk Index kn-keyword=Geriatric Nutritional Risk Index en-keyword=nutritional status kn-keyword=nutritional status en-keyword=Prognostic Nutritional Index kn-keyword=Prognostic Nutritional Index END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=31 article-no= start-page=e202301644 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230817 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Polymer Template Synthesis of CuOx/Clay Nanocomposites with Controllable CuOx Formation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Metal oxides have the excellent functions including high thermal stability, electrical properties, catalytic performance, and adsorption properties of acid gases such as CO2 via the acid-base interactions. However, they suffer from low reserves, porosity control, and low adsorption efficiency per weight compared with lightweight materials including carbon and silica. To solve these issues, various methods for supporting metal oxides on porous carriers, such as decomposition-precipitation and impregnation, have been investigated, but controlling the formation of metal oxide on clay nanosheets remains as a challenge. Herein, we developed a soft-template method for supporting metal oxide (CuOx) nanoparticles on activated clay nanosheets. The intercalation of polyethyleneimine (PEI)−Cu2+ complexes between the layers of clay nanosheets followed by calcination to construct CuOx and remove the PEI templates afforded CuOx/clay nanocomposites. The constructed CuOx/clay nanocomposites had the close porosity to that of clay. Tuning the Cu2+/PEI ratio in PEI−Cu2+ complex allowed to control CuOx states (loadings, particle sizes, etc.). Tuning of the supporting conditions allowed constructing a structure suitable for CO2 uptake. These findings will contribute to the development of the material science of metal oxide nanoparticles and their hybrid materials in diverse fields including CO2 adsorbents, energy devices, and catalysts. en-copyright= kn-copyright= en-aut-name=TakeuchiYuki en-aut-sei=Takeuchi en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhkuboTakahiro en-aut-sei=Ohkubo en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Inorganic Chemistry Laboratory, Graduate School of Natural Science & Technology, Okayama University kn-affil= affil-num=2 en-affil=Inorganic Chemistry Laboratory, Graduate School of Natural Science & Technology, Okayama University kn-affil= en-keyword=Clay nanosheets kn-keyword=Clay nanosheets en-keyword=CO2 adsorption kn-keyword=CO2 adsorption en-keyword=Metal oxide nanoparticles kn-keyword=Metal oxide nanoparticles en-keyword=Nanocomposites kn-keyword=Nanocomposites en-keyword=Template method kn-keyword=Template method 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=20230823 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Low frequency of intracranial progression in advanced NSCLC patients treated with cancer immunotherapies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Intracranial metastases are common in nonsmall-cell lung cancer (NSCLC) patients, whose prognosis is very poor. In addition, intracranial progression is common during systemic treatments due to the inability to penetrate central nervous system (CNS) barriers, whereas the intracranial effects of cancer immunotherapies remain unclear. We analyzed clinical data to evaluate the frequency of intracranial progression in advanced NSCLC patients treated with PD-1 blockade therapies compared with those treated without PD-1 blockade therapies, and found that the frequency of intracranial progression in advanced NSCLC patients treated with PD-1 blockade therapies was significantly lower than that in patients treated with cytotoxic chemotherapies. In murine models, intracranial rechallenged tumors after initial rejection by PD-1 blockade were suppressed. Accordingly, long-lived memory precursor effector T cells and antigen-specific T cells were increased by PD-1 blockade in intracranial lesions. However, intracranial rechallenged different tumors are not suppressed. Our results indicate that cancer immunotherapies can prevent intracranial progression, maintaining long-term effects intracranially as well as systemically. If intracranial recurrence occurs during the treatment with PD-1 blockade therapies, aggressive local therapies could be worthwhile. en-copyright= kn-copyright= en-aut-name=KemmotsuNaoya

antioxidant that protects against oxidative damage by regulating the dithiol/disulfide balance of interacting proteins. We recently discovered the Adem rat, an epileptic rat harboring the Txn1-F54L mutation, characterized by wild running and vacuolar degeneration in the midbrain. This study aimed to characterize the classification of epilepsy in Adem rats. We performed simultaneous video-electroencephalographic recordings, magnetic resonance imaging, neurotransmitter measurements using gas chromatography–mass spectrometry (GC-MS), and immunohistochemistry. Adem rats exhibited absence, tonic, and focal seizures. The type of epilepsy was classified as combined generalized and focal epilepsy. Neurotransmitters in the midbrain and cortex were measured at 3 weeks of age, when neuronal cell death occurs in the midbrain. The results of GC-MS ruled out the dominance of the excitatory system in the midbrain and cortex of Adem rats. Activation of astrocytes and microglia was more pronounced at 5 weeks of age, at which time epileptic seizures occurred frequently. The underlying pathology in Adem rats remains unknown. However, glial cell activation and inflammation may play a significant role in the occurrence of epilepsy. en-copyright= kn-copyright= en-aut-name=OhmoriIori en-aut-sei=Ohmori en-aut-mei=Iori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OuchidaMamoru en-aut-sei=Ouchida en-aut-mei=Mamoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShinoharaMasakazu en-aut-sei=Shinohara en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KobayashiKiyoka en-aut-sei=Kobayashi en-aut-mei=Kiyoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshidaSaeko en-aut-sei=Ishida en-aut-mei=Saeko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MashimoTomoji en-aut-sei=Mashimo en-aut-mei=Tomoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Section of Developmental Physiology and Pathology, Faculty of Education, Okayama University kn-affil= affil-num=2 en-affil=Department of Molecular Oncology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Division of Epidemiology, Kobe University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Otsuka Pharmaceutical kn-affil= affil-num=5 en-affil=Division of Animal Genetics, Laboratory Animal Research Center, Institute of Medical Science, University of Tokyo kn-affil= affil-num=6 en-affil=Division of Animal Genetics, Laboratory Animal Research Center, Institute of Medical Science, University of Tokyo kn-affil= en-keyword=animal model kn-keyword=animal model en-keyword=combined generalized and focal epilepsy kn-keyword=combined generalized and focal epilepsy en-keyword=oxidative stress kn-keyword=oxidative stress en-keyword=thioredoxin kn-keyword=thioredoxin END start-ver=1.4 cd-journal=joma no-vol=114 cd-vols= no-issue=11 article-no= start-page=4343 end-page=4354 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230915 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy of gilteritinib in comparison with alectinib for the treatment of ALK-rearranged non-small cell lung cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Gilteritinib is a multitarget tyrosine kinase inhibitor (TKI), approved for the treatment of FLT3-mutant acute myeloid leukemia, with a broad range of activity against several tyrosine kinases including anaplastic lymphoma kinase (ALK). This study investigated the efficacy of gilteritinib against ALK-rearranged non-small cell lung cancers (NSCLC). To this end, we assessed the effects of gilteritinib on cell proliferation, apoptosis, and acquired resistance responses in several ALK-rearranged NSCLC cell lines and mouse xenograft tumor models and compared its efficacy to alectinib, a standard ALK inhibitor. Gilteritinib was significantly more potent than alectinib, as it inhibited cell proliferation at a lower dose, with complete attenuation of growth observed in several ALK-rearranged NSCLC cell lines and no development of drug tolerance. Immunoblotting showed that gilteritinib strongly suppressed phosphorylated ALK and its downstream effectors, as well as mesenchymal-epithelial transition factor (MET) signaling. By comparison, MET signaling was enhanced in alectinib-treated cells. Furthermore, gilteritinib was found to more effectively abolish growth of ALK-rearranged NSCLC xenograft tumors, many of which completely receded. Interleukin-15 (IL-15) mRNA levels were elevated in gilteritinib-treated cells, together with a concomitant increase in the infiltration of tumors by natural killer (NK) cells, as assessed by immunohistochemistry. This suggests that IL-15 production along with NK cell infiltration may constitute components of the gilteritinib-mediated antitumor responses in ALK-rearranged NSCLCs. In conclusion, gilteritinib demonstrated significantly improved antitumor efficacy compared with alectinib against ALK-rearranged NSCLC cells, which can warrant its candidacy for use in anticancer regimens, after further examination in clinical trial settings. en-copyright= kn-copyright= en-aut-name=AndoChihiro en-aut-sei=Ando en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei=

population: The CANPIONE study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim: To evaluate the effect of canagliflozin, a sodium-glucose co-transporter-2 (SGLT2) inhibitor, on albuminuria and the decline of estimated glomerular filtration rate (eGFR) in participants with type 2 diabetes and microalbuminuria.
Methods: The CANPIONE study is a multicentre, randomized, parallel-group and open-labelled study consisting of a unique 24-week preintervention period, during which the rate of eGFR decline before intervention is estimated, followed by a 52-week intervention and a 4-week washout period. Participants with a geometric mean urinary albumin-to-creatinine ratio (UACR) of 50 and higher and less than 300 mg/g in two consecutive first-morning voids at two different time points, and an eGFR of 45 ml/min/1.73m2 or higher, are randomly assigned to receive canagliflozin 100 mg daily or to continue guideline-recommended treatment, except for SGLT2 inhibitors. The first primary outcome is the change in UACR, and the second primary outcome is the change in eGFR slope.
Results: A total of 258 participants were screened and 98 were randomized at 21 sites in Japan from August 2018 to May 2021. The mean baseline age was 61.4 years and 25.8% were female. The mean HbA1c was 7.9%, mean eGFR was 74.1 ml/min/1.73m2 and median UACR was 104.2 mg/g.
Conclusions: The CANPIONE study will determine whether the SGLT2 inhibitor canagliflozin can reduce albuminuria and slow eGFR decline in participants with type 2 diabetes and microalbuminuria. en-copyright= kn-copyright= en-aut-name=MiyamotoSatoshi en-aut-sei=Miyamoto en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HeerspinkHiddo J.

analysis and its software named EcheScan for spatial lattice data. EcheScan is developed as a web application via an internet browser in R language and Shiny server for echelon analysis. The technique of echelon is proposed to analyze the topological structure for spatial lattice data. The echelon tree provides a dendrogram representation. Regional features, such as hierarchical spatial data structure and hotspots clusters, are shown in an echelon dendrogram. In addition, we introduce the conception of echelon with the values and neighbors for lattice data. We also explain the use of EcheScan for one- and two-dimensional regular lattice data. Furthermore, coronavirus disease 2019 death data corresponding to 50 US states are illustrated using EcheScan as an example of geospatial lattice data.

We report the treatment outcomes and endoscopic removal methods for migrated stents using a double-balloon enteroscope (DBE). We retrospectively studied 12 patients with stent migration into the main pancreatic duct (MPD) or bile duct who underwent bowel reconstruction between January 2012 and June 2020. The successful removal rates in the MPD (n = 3) and the bile duct (n = 9) were 66.7% (2/3) and 88.9% (8/9), respectively. The removal techniques included the indirect method (n = 3), the direct method (n = 4), and a combination of indirect and direct methods (n = 3). The removal devices included an extraction balloon catheter (n = 7), basket catheter (n = 5), biopsy forceps (n = 3), and snare (n = 2). Stent removal using a DBE was feasible and useful as the first treatment for patients with bowel reconstruction. The choice of the direct and/or indirect method according to the situation of the migrated stent is important. en-copyright= kn-copyright= en-aut-name=OdaTakashi en-aut-sei=Oda en-aut-mei=Takashi 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=UetaEijiro en-aut-sei=Ueta en-aut-mei=Eijiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HimeiHitomi en-aut-sei=Himei en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OgawaTaiji en-aut-sei=Ogawa en-aut-mei=Taiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TerasawaHiroyuki en-aut-sei=Terasawa en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 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=9 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=10 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=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, 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 Gastroenterology, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= en-keyword=double-balloon enteroscope (DBE) kn-keyword=double-balloon enteroscope (DBE) en-keyword=stent migration kn-keyword=stent migration en-keyword=stent removal kn-keyword=stent removal END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=1 article-no= start-page=e83 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211209 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fever and electrocoagulation syndrome after colorectal endoscopic submucosal dissection for patients with immunosuppressants and steroids en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Transient fever and electrocoagulation syndrome after colorectal endoscopic submucosal dissection (ESD) remain a challenge. The aim of this study was to assess the risk factors of post-ESD fever and post-ESD coagulation syndrome (PECS), focusing on the involvement of immunosuppressive drugs and steroids (IM).
Methods: This retrospective analysis included 510 patients who underwent colorectal ESD at Okayama University Hospital from 2015 to 2020. The incidence rate, clinical outcome, and factors associated with post-ESD fever and PECS were investigated.
Results: Post-ESD fever and PECS occurred in 63 patients (12.4%) and 43 patients (8.4%), respectively. In multivariate analysis, the American Society of Anesthesiologists Physical Status ≥3, the use of immunosuppressants or prednisolone ≥5mg (IM group), and injury to muscle layer/perforation were significantly associated with post-ESD fever. In PECS, IM group, tumors located on the right side, treatment time ≥60 min, injury to the muscle layer, and multiple lesions were independent risk factors. Both post-ESD fever and PECS improved conservatively in the IM group, and no serious complication was observed.
Conclusions: The use of IM was a risk factor for both post-ESD fever and PECS. However, there were no serious complications in colorectal ESD for patients taking IM. en-copyright= kn-copyright= en-aut-name=YamamotoShumpei en-aut-sei=Yamamoto en-aut-mei=Shumpei kn-aut-name=

biliary obstruction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Biliary drainage for unresectable malignant hilar biliary obstruction (UMHBO) is still associated with a number of controversies to be resolved. The superiority of bilateral drainage in comparison to unilateral drainage has not been proven obviously yet. However, bilateral drainage is necessary to treat obstructive jaundice in some UMHBO patients, and this may be connected with preservation of the functional liver volume. The partial stent-in-stent (SIS) method and side-by-side (SBS) method developed as bilateral drainage methods. There is no significant difference in the technical or clinical success rates of the SIS and SBS methods. In addition, these methods are comparable in terms of adverse events, patency period, and survival period. On the other hand, reintervention for recurrent biliary obstruction (RBO) after the SBS method seems to be easier in comparison to cases with RBO after the SIS method; however, there is no remarkable difference in the clinical results of these procedures. Endoscopic ultrasound (EUS)-guided biliary drainage also has become an option for patients with UMHBO. Left hepatic drainage using EUS-guided hepaticogastrostomy (EUS-HGS) has become common; however, few studies have reported the results of bridging drainage for the right lobe using the EUS-HGS route or EUS-guided hepaticojejunostomy. A few studies addressed the results of newly designed stents, such as the 6-mm braided metal stent and inside stent. The development of various drainage methods and new devices is necessary for the further advancement of endoscopic biliary drainage for patients with UMHBO, further studies to evaluate those methods and devices are warranted. en-copyright= kn-copyright= en-aut-name=KatoHironari en-aut-sei=Kato en-aut-mei=Hironari 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=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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= en-keyword=biliary drainage kn-keyword=biliary drainage en-keyword=EUS-BD kn-keyword=EUS-BD en-keyword=malignant hilar biliary obstruction kn-keyword=malignant hilar biliary obstruction en-keyword=side-by-side kn-keyword=side-by-side en-keyword=stent-in-stent kn-keyword=stent-in-stent END start-ver=1.4 cd-journal=joma no-vol=236 cd-vols= no-issue=3 article-no= start-page=864 end-page=877 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220817 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A tonoplast‐localized magnesium transporter is crucial for stomatal opening in Arabidopsis under high Mg2+ conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Plant stomata play an important role in CO2 uptake for photosynthesis and transpiration, but the mechanisms underlying stomatal opening and closing under changing environmental conditions are still not completely understood.
Through large-scale genetic screening, we isolated an Arabidopsis mutant (closed stomata2 (cst2)) that is defective in stomatal opening. We cloned the causal gene (MGR1/CST2) and functionally characterized this gene.
The mutant phenotype was caused by a mutation in a gene encoding an unknown protein with similarities to the human magnesium (Mg2+) efflux transporter ACDP/CNNM. MGR1/CST2 was localized to the tonoplast and showed transport activity for Mg2+. This protein was constitutively and highly expressed in guard cells. Knockout of this gene resulted in stomatal closing, decreased photosynthesis and growth retardation, especially under high Mg2+ conditions, while overexpression of this gene increased stomatal opening and tolerance to high Mg2+ concentrations. Furthermore, guard cell-specific expression of MGR1/CST2 in the mutant partially restored its stomatal opening.
Our results indicate that MGR1/CST2 expression in the leaf guard cells plays an important role in maintaining cytosolic Mg2+ concentrations through sequestering Mg2+ into vacuoles, which is required for stomatal opening, especially under high Mg2+ conditions. en-copyright= kn-copyright= en-aut-name=InoueShin‐ichiro en-aut-sei=Inoue en-aut-mei=Shin‐ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayashiMaki en-aut-sei=Hayashi en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HuangSheng en-aut-sei=Huang en-aut-mei=Sheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YokoshoKengo en-aut-sei=Yokosho en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GotohEiji en-aut-sei=Gotoh en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IkematsuShuka en-aut-sei=Ikematsu en-aut-mei=Shuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkumuraMasaki en-aut-sei=Okumura en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SuzukiTakamasa en-aut-sei=Suzuki en-aut-mei=Takamasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KamuraTakumi en-aut-sei=Kamura en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KinoshitaToshinori en-aut-sei=Kinoshita en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= affil-num=1 en-affil=Division of Biological Science, Graduate School of Science, Nagoya University kn-affil= affil-num=2 en-affil=Division of Biological Science, Graduate School of Science, Nagoya University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Department of Forest Environmental Sciences, Faculty of Agriculture, Kyushu University kn-affil= affil-num=6 en-affil=Institute of Transformative Bio-Molecules (WPI-ITbM), Nagoya University kn-affil= affil-num=7 en-affil=Division of Biological Science, Graduate School of Science, Nagoya University kn-affil= affil-num=8 en-affil=Department of Biological Chemistry, College of Bioscience and Biotechnology, Chubu University kn-affil= affil-num=9 en-affil=Division of Biological Science, Graduate School of Science, Nagoya University kn-affil= affil-num=10 en-affil=Division of Biological Science, Graduate School of Science, Nagoya University kn-affil= affil-num=11 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=ACDP kn-keyword=ACDP en-keyword=CNNM kn-keyword=CNNM en-keyword=Arabidopsis thaliana kn-keyword=Arabidopsis thaliana en-keyword=magnesium transport kn-keyword=magnesium transport en-keyword=plant growth kn-keyword=plant growth en-keyword=stomatal opening kn-keyword=stomatal opening 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=20230717 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Neuropeptidergic control circuits in the spinal cord for male sexual behaviour: Oxytocin–gastrin‐releasing peptide systems en-subtitle= kn-subtitle= en-abstract= kn-abstract=The neuropeptidergic mechanisms controlling socio-sexual behaviours consist of complex neuronal circuitry systems in widely distributed areas of the brain and spinal cord. At the organismal level, it is now becoming clear that “hormonal regulations” play an important role, in addition to the activation of neuronal circuits. The gastrin-releasing peptide (GRP) system in the lumbosacral spinal cord is an important component of the neural circuits that control penile reflexes in rats, circuits that are commonly referred to as the “spinal ejaculation generator (SEG).” Oxytocin, long known as a neurohypophyseal hormone, is now known to be involved in the regulation of socio-sexual behaviors in mammals, ranging from social bonding to empathy. However, the functional interaction between the SEG neurons and the hypothalamo-spinal oxytocin system remains unclear. Oxytocin is known to be synthesised mainly in hypothalamic neurons and released from the posterior pituitary into the circulation. Oxytocin is also released from the dendrites of the neurons into the hypothalamus where they have important roles in social behaviours via non-synaptic volume transmission. Because the most familiar functions of oxytocin are to regulate female reproductive functions including parturition, milk ejection, and maternal behaviour, oxytocin is often thought of as a “feminine” hormone. However, there is evidence that a group of parvocellular oxytocin neurons project to the lower spinal cord and control male sexual function in rats. In this report, we review the functional interaction between the SEG neurons and the hypothalamo-spinal oxytocin system and effects of these neuropeptides on male sexual behaviour. Furthermore, we discuss the finding of a recently identified, localised “volume transmission” role of oxytocin in the spinal cord. Findings from our studies suggest that the newly discovered “oxytocin-mediated spinal control of male sexual function” may be useful in the treatment of erectile and ejaculatory dysfunction. en-copyright= kn-copyright= en-aut-name=OtiTakumi en-aut-sei=Oti en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakamotoHirotaka en-aut-sei=Sakamoto en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Ushimado Marine Institute (UMI), Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Ushimado Marine Institute (UMI), Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=gastrin-releasing peptide kn-keyword=gastrin-releasing peptide en-keyword=male sexual function kn-keyword=male sexual function en-keyword=non-synaptic volume transmission kn-keyword=non-synaptic volume transmission en-keyword=oxytocin kn-keyword=oxytocin en-keyword=spinal cord kn-keyword=spinal cord END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=5 article-no= start-page=317 end-page=319 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230725 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Task shifting of medical office works: A preliminary questionnaire survey for generalists en-subtitle= kn-subtitle= en-abstract= kn-abstract=To reduce physician burden, task shifting of clerical work from physicians to medical assistants is being promoted; however, it depends on hospitals. A questionnaire survey was conducted among 40 general physicians at Okayama University Hospital in December 2022 to investigate physicians' preferences toward task shifting. Compared to other tasks, most physicians thought that ordering examinations (14, 47%), replying to referral letters (19, 63%), and prescriptions (21, 70%) and medical record entries (22, 73%) should not be task shifted. Physicians' controversial opinions on task shifting maybe the reason behind the slow progress in task shifting. en-copyright= kn-copyright= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=SunadaNaruhiko en-aut-sei=Sunada en-aut-mei=Naruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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 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 General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=burnout kn-keyword=burnout en-keyword=clerical work kn-keyword=clerical work en-keyword=medical assistant kn-keyword=medical assistant en-keyword=overwork kn-keyword=overwork en-keyword=task shift kn-keyword=task shift END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=8 article-no= start-page=e7771 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230802 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Preoperative detection of functional somatostatin receptors in a patient with an insulinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Octreotide is used in patients with insulinomas to treat hypoglycemia, and somatostatin receptor (SSTR) 2 expression is important for its efficacy.

A product comprising H2O2 and sodium hyaluronate has been developed as a radiosensitizer. However, the effects of H2O2 on antitumor immunity remain unclear. To investigate the effects of H2O2, especially the abscopal effect when combined with radiotherapy (RT), we implanted murine tumor cells simultaneously in two locations in mouse models: the hind limb and back. H2O2 mixed with sodium hyaluronate was injected intratumorally, followed by irradiation only at the hind limb lesion. No treatment was administered to the back lesion. The H2O2/RT combination significantly reduced tumor growth at the noninjected/nonirradiated site in the back lesion, whereas H2O2 or RT individually did not reduce tumor growth. Flow cytometric analyses of the tumor-draining lymph nodes in the injected/irradiated areas showed that the number of dendritic cells increased significantly with maturation in the H2O2/RT combination group. In addition, analyses of tumor-infiltrating lymphocytes showed that the number of CD8+ (cluster of differentiation 8) T cells and the frequency of IFN-γ+ (interferon gamma) CD8+ T cells were higher in the noninjected/nonirradiated tumors in the H2O2/RT group compared to those in the other groups. PD-1 (programmed death receptor 1) blockade further increased the antitumor effect against noninjected/nonirradiated tumors in the H2O2/RT group. Intratumoral injection of H2O2 combined with RT therefore induces an abscopal effect by activating antitumor immunity, which can be further enhanced by PD-1 blockade. These findings promote the development of H2O2/RT therapy combined with cancer immunotherapies, even for advanced cancers. en-copyright= kn-copyright= en-aut-name=KemmotsuNaoya en-aut-sei=Kemmotsu en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZhuLi en-aut-sei=Zhu en-aut-mei=Li kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NagasakiJoji en-aut-sei=Nagasaki en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UedaYouki en-aut-sei=Ueda en-aut-mei=Youki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DansakoHiromichi en-aut-sei=Dansako en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FangYue en-aut-sei=Fang en-aut-mei=Yue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=TogashiYosuke en-aut-sei=Togashi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Tumor Microenvironment, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Tumor Microenvironment, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Tumor Microenvironment, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Tumor Microenvironment, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Tumor Microenvironment, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Microbial and Biochemical Pharmacy, School of Pharmacy, China Medical University kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Tumor Microenvironment, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=abscopal effect kn-keyword=abscopal effect en-keyword=dendritic cell kn-keyword=dendritic cell en-keyword=hydrogen peroxide kn-keyword=hydrogen peroxide en-keyword=radiosensitizer kn-keyword=radiosensitizer en-keyword=radiotherapy kn-keyword=radiotherapy en-keyword=tumor-draining lymph node kn-keyword=tumor-draining lymph node END start-ver=1.4 cd-journal=joma no-vol=43 cd-vols= no-issue=4 article-no= start-page=553 end-page=560 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230719 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=At-risk internet addiction and related factors among senior high school teachers in Japan based on a Nationwide survey en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Internet addiction (IA) has been drawing attention to mental health. However, few reports have been found on the related factors of at-risk IA among regular workers by a nationwide survey. The study aimed to evaluate the characteristics of at-risk IA and identify related factors among senior high school teachers in Japan.
Methods:This survey was a cross-sectional survey of high schools across Japan in 2017. There were 3189 teachers (2088 males and 1098 female) who participated in this survey. The questionnaire asked about their devices, both the time and the activities of using their internet, and sociodemographic factors. IA was measured by the internet addiction test (IAT) by which 40-79 points were classified as at-risk IA, and more as IA. We compared the related factors of at-risk IA and non-IA using descriptive analysis and multivariable regression analysis.
Results: The rates of IA and at-risk IA were 0.09% (n = 3) and 6.91% (n = 220), respectively. At-risk IA was positively associated with activities on the internet for gaming, entertainment, net-surfing, and younger ages. In addition, the at-risk IA group had a longer time spent on the internet than the non-IA group.
Conclusions: Around 7% of high school teachers are at-risk IA in this survey, though they have regular work. Our results suggest that at-risk IA may be reinforced not only by the active internet use such as gaming, but also by purposeless behaviors, such as net-surfing. Managing time on the internet may support preventing at-risk IA among senior high school teachers. en-copyright= kn-copyright= en-aut-name=FukudaMari en-aut-sei=Fukuda en-aut-mei=Mari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ChowdhuryMohammad en-aut-sei=Chowdhury en-aut-mei=Mohammad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ChowdhuryTanvir Turin en-aut-sei=Chowdhury en-aut-mei=Tanvir Turin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsumuraHideki en-aut-sei=Tsumura en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsuchieRina en-aut-sei=Tsuchie en-aut-mei=Rina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KinutaMinako en-aut-sei=Kinuta en-aut-mei=Minako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=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= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=University of Calgary kn-affil= affil-num=3 en-affil=University of Calgary kn-affil= affil-num=4 en-affil=Tokushima University kn-affil= affil-num=5 en-affil=Shimane University kn-affil= affil-num=6 en-affil=Okayama University kn-affil= affil-num=7 en-affil=Okayama University kn-affil= affil-num=8 en-affil=Okayama University kn-affil= en-keyword=epidemiology of mental disorders kn-keyword=epidemiology of mental disorders en-keyword=internet addiction kn-keyword=internet addiction en-keyword=Nationwide survey kn-keyword=Nationwide survey en-keyword=preventive medicine kn-keyword=preventive medicine en-keyword=teachers kn-keyword=teachers END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e15077 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230717 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Percentage of low attenuation area on computed tomography detects chronic lung allograft dysfunction, especially bronchiolitis obliterans syndrome, after bilateral lung transplantation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: The percentage of low attenuation area (%LAA) on computed tomography (CT) is useful for evaluating lung emphysema, and higher %LAA was observed in patients with chronic lung allograft dysfunction (CLAD). This study investigated the relationship between the %LAA and the development of CLAD after bilateral lung transplantation (LT).
Methods: We conducted a single-center retrospective study of 75 recipients who underwent bilateral LT; the recipients were divided into a CLAD group (n = 30) and a non-CLAD group (n = 45). The %LAA was calculated using CT and compared between the two groups from 4 years before to 4 years after the diagnosis of CLAD. The relationships between the %LAA and the percent baseline values of the pulmonary function test parameters were also calculated.
Results: The %LAA was significantly higher in the CLAD group than in the non-CLAD group from 2 years before to 2 years after the diagnosis of CLAD (P < .05). In particular, patients with bronchiolitis obliterans syndrome (BOS) exhibited significant differences even from 4 years before to 4 years after diagnosis (P < .05). Significant negative correlations between the %LAA and the percent baseline values of the forced expiratory volume in 1 s (r = −.36, P = .0031), the forced vital capacity (r = −.27, P = .027), and the total lung capacity (r = −.40, P < .001) were seen at the time of CLAD diagnosis.
Conclusion: The %LAA on CT was associated with the development of CLAD and appears to have the potential to predict CLAD, especially BOS, after bilateral LT. 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=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=ShiotaniToshio en-aut-sei=Shiotani en-aut-mei=Toshio 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=HashimotoKohei en-aut-sei=Hashimoto en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 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=9 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=10 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=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= affil-num=1 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= en-keyword=bronchiolitis obliterans syndrome kn-keyword=bronchiolitis obliterans syndrome en-keyword=chronic lung allograft dysfunction kn-keyword=chronic lung allograft dysfunction en-keyword=computed tomography kn-keyword=computed tomography en-keyword=lung transplantation kn-keyword=lung transplantation en-keyword=restrictive allograft syndrome kn-keyword=restrictive allograft syndrome END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=10 article-no= start-page=1148 end-page=1156 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230713 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Role of glycosylphosphatidylinositol-anchored high-density lipoprotein binding protein 1 in hypertriglyceridemia and diabetes en-subtitle= kn-subtitle= en-abstract= kn-abstract=In diabetes, the impairment of insulin secretion and insulin resistance contribute to hypertriglyceridemia, as the enzymatic activity of lipoprotein lipase (LPL) depends on insulin action. The transport of LPL to endothelial cells and its enzymatic activity are maintained by the formation of lipolytic complex depending on the multiple positive (glycosylphosphatidylinositol-anchored high-density lipoprotein binding protein 1 [GPIHBP1], apolipoprotein C-II [APOC2], APOA5, heparan sulfate proteoglycan [HSPG], lipase maturation factor 1 [LFM1] and sel-1 suppressor of lin-12-like [SEL1L]) and negative regulators (APOC1, APOC3, angiopoietin-like proteins [ANGPTL]3, ANGPTL4 and ANGPTL8). Among the regulators, GPIHBP1 is a crucial molecule for the translocation of LPL from parenchymal cells to the luminal surface of capillary endothelial cells, and maintenance of lipolytic activity; that is, hydrolyzation of triglyceride into free fatty acids and monoglyceride, and conversion from chylomicron to chylomicron remnant in the exogenous pathway and from very low-density lipoprotein to low-density lipoprotein in the endogenous pathway. The null mutation of GPIHBP1 causes severe hypertriglyceridemia and pancreatitis, and GPIGBP1 autoantibody syndrome also causes severe hypertriglyceridemia and recurrent episodes of acute pancreatitis. In patients with type 2 diabetes, the elevated serum triglyceride levels negatively correlate with circulating LPL levels, and positively with circulating APOC1, APOC3, ANGPTL3, ANGPTL4 and ANGPTL8 levels. In contrast, circulating GPIHBP1 levels are not altered in type 2 diabetes patients with higher serum triglyceride levels, whereas they are elevated in type 2 diabetes patients with diabetic retinopathy and nephropathy. The circulating regulators of lipolytic complex might be new biomarkers for lipid and glucose metabolism, and diabetic vascular complications. en-copyright= kn-copyright= en-aut-name=KurookaNaoko en-aut-sei=Kurooka en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EguchiJun en-aut-sei=Eguchi en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Dibaetes kn-keyword=Dibaetes en-keyword=GPIHBP1 kn-keyword=GPIHBP1 en-keyword=Lipoprotein lipase kn-keyword=Lipoprotein lipase END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=10 article-no= start-page=e028706 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230516 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Significant Delayed Activation on the Right Ventricular Outflow Tract Represents Complete Right Bundle-Branch Block Pattern in Brugada Syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The appearance of complete right bundle-branch block (CRBBB) in Brugada syndrome (BrS) is associated with an increased risk of ventricular fibrillation. The pathophysiological mechanism of CRBBB in patients with BrS has not been well established. We aimed to clarify the significance of a conduction delay zone associated with arrhythmias on CRBBB using body surface mapping in patients with BrS.
Methods and Results: Body surface mapping was recorded in 11 patients with BrS and 8 control patients both with CRBBB. CRBBB in control patients was transiently exhibited by unintentional catheter manipulation (proximal RBBB). Ventricular activation time maps were constructed for both of the groups. We divided the anterior chest into 4 areas (inferolateral right ventricle [RV], RV outflow tract [RVOT], intraventricular septum, and left ventricle) and compared activation patterns between the 2 groups. Excitation propagated to the RV from the left ventricle through the intraventricular septum with activation delay in the entire RV in the control group (proximal RBBB pattern). In 7 patients with BrS, excitation propagated from the inferolateral RV to the RVOT with significant regional activation delay. The remaining 4 patients with BrS showed a proximal RBBB pattern with the RVOT activation delay. The ventricular activation time in the inferolateral RV was significantly shorter in patients with BrS without a proximal RBBB pattern than in control patients.
Conclusions: The CRBBB morphology in patients with BrS consisted of 2 mechanisms: (1) significantly delayed conduction in the RVOT and (2) proximal RBBB with RVOT conduction delay. Significant RVOT conduction delay without proximal RBBB resulted in CRBBB morphology in patients with BrS. en-copyright= kn-copyright= en-aut-name=MorimotoYoshimasa en-aut-sei=Morimoto en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoritaHiroshi en-aut-sei=Morita en-aut-mei=Hiroshi 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=MizunoTomofumi en-aut-sei=Mizuno en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasudaTakuro en-aut-sei=Masuda en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UeokaAkira en-aut-sei=Ueoka en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AsadaSaori en-aut-sei=Asada en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyamotoMasakazu en-aut-sei=Miyamoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KawadaSatoshi en-aut-sei=Kawada en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakagawaKoji en-aut-sei=Nakagawa en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NishiiNobuhiro en-aut-sei=Nishii en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 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=13 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Therapeutics , Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Cardiovascular Therapeutics , Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= en-keyword=activation pattern kn-keyword=activation pattern en-keyword=body surface map kn-keyword=body surface map en-keyword=Brugada syndrome kn-keyword=Brugada syndrome en-keyword=complete right bundle-branch block kn-keyword=complete right bundle-branch block 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=20230609 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficient granulocyte collection method using high concentrations of medium molecular weight hydroxyethyl starch en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Granulocyte transfusion therapy is a rational therapeutic option for patients with prolonged, severe neutropenia. Although high molecular weight hydroxyethyl starch (hHES) facilitates the separation of red blood cells during granulocyte collection, renal dysfunction has been noted as a potential side effect. HES130/0.4 (Voluven®) is a medium molecular weight HES (mHES) with superior safety profiles compared to hHES. Although HES130/0.4 is reportedly effective in the collection of granulocytes, we lack studies comparing the efficiency of granulocyte collection using HES130/0.4 and hHES.
Study Design and Methods: We retrospectively collected the data from 60 consecutive apheresis procedures performed on 40 healthy donors at the Okayama University Hospital between July 2013 and December 2021. All procedures were performed using the Spectra Optia system. Based on the HES130/0.4 concentration in the separation chamber, granulocyte collection methods using HES130/0.4 were classified into m0.46, m0.44, m0.37, and m0.8 groups. We used HES130/0.4 and hHES groups to compare the various sample collection methods.
Results: The median granulocyte collection efficiency (CE) was approximately 24.0% and 28.1% in the m0.8 and hHES groups, respectively, which were significantly higher than those in the m0.46, m0.44, and m0.37 groups. One month following granulocyte collection with HES130/0.4, no significant changes were observed in serum creatinine levels compared to those before the donation.
Conclusion: Therefore, we propose a granulocyte collection approach employing HES130/0.4, which is comparable to the use of hHES in terms of the granulocyte CE. A high concentration of HES130/0.4 in the separation chamber was considered crucial for granulocyte collection. en-copyright= kn-copyright= en-aut-name=KondoTakumi en-aut-sei=Kondo en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=SumiiYuichi en-aut-sei=Sumii en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UrataTomohiro en-aut-sei=Urata en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KimuraMaiko en-aut-sei=Kimura en-aut-mei=Maiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsudaMasayuki en-aut-sei=Matsuda en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IkegawaShuntaro en-aut-sei=Ikegawa en-aut-mei=Shuntaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=WashioKana en-aut-sei=Washio en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=11 ORCID= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 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=14 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=15 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=16 ORCID= affil-num=1 en-affil=Division of Transfusion, Okayama University Hospital kn-affil= affil-num=2 en-affil=Division of Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=3 en-affil=Division of Transfusion, Okayama University Hospital kn-affil= affil-num=4 en-affil=Division of Transfusion, Okayama University Hospital kn-affil= affil-num=5 en-affil=Division of Transfusion, Okayama University Hospital kn-affil= affil-num=6 en-affil=Division of Transfusion, Okayama University Hospital kn-affil= affil-num=7 en-affil=Division of Transfusion, Okayama University Hospital kn-affil= affil-num=8 en-affil=Division of Transfusion, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Pediatrics/Pediatric Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=14 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=15 en-affil=Division of Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=16 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= en-keyword=blood center operations kn-keyword=blood center operations en-keyword=cellular therapy kn-keyword=cellular therapy en-keyword=therapeutic apheresis kn-keyword=therapeutic apheresis END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=6 article-no= start-page=e7595 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230620 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=ANCA-associated vasculitis with scleritis, corneal melt, and perforation rescued by rituximab: Case report and literature review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Key Clinical Message: Patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis, specifically with myeloperoxidase (MPO)-ANCA, would have a risk for developing corneal melt and perforation abruptly in a short period. It is desirable to have a team of collaboration of rheumatologists and other specialties.
Abstract: An 80-year old man who had been diagnosed 5.5 years previously as ANCA-associated vasculitis by temporal artery biopsy developed corneal melt and perforation with scleritis in both eyes. He underwent successful cataract surgery and retained ambulatory vision with the aid of intravenous rituximab. Two additional patients with similar manifestations were found in the literature. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= 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=2 ORCID= en-aut-name=SawachikaHiroshi en-aut-sei=Sawachika en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishimuraHirotake en-aut-sei=Nishimura en-aut-mei=Hirotake kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=Department of Rheumatology, Kawasaki Medical School kn-affil= affil-num=3 en-affil=Department of Rheumatology, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of Pathology, Kawasaki Medical School kn-affil= en-keyword=ANCA-associated vasculitis kn-keyword=ANCA-associated vasculitis en-keyword=corneal melt and perforation kn-keyword=corneal melt and perforation en-keyword=rituximab kn-keyword=rituximab en-keyword=scleritis kn-keyword=scleritis en-keyword=temporal artery biopsy kn-keyword=temporal artery biopsy END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=4 article-no= start-page=2447 end-page=2457 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230531 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association of perivascular fat attenuation on computed tomography and heart failure with preserved ejection fraction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims　Heart failure with a preserved ejection fraction (HFpEF) is associated with chronic inflammation. We aimed to investigate the association between pericoronary adipose tissue attenuation (PCATA) on coronary computed tomography angiography as a novel noninvasive marker of pericoronary inflammation and the presence of HFpEF.
Methods and results　This retrospective study included 607 outpatients (median age, 65 years; 50% male) who underwent both echocardiography and coronary computed tomography angiography. Patients with obstructive coronary artery disease were excluded from this study. PCATA was compared between patients with and without HFpEF, which was diagnosed according to the Heart Failure Association (HFA)-PEFF score. PCATA was assessed at the proximal 40-mm segments of all three major coronary arteries on coronary computed tomography angiography. Patients with HFpEF had higher PCATA in all coronary arteries compared to the control participants: left anterior descending artery (LAD), -65.2 +/- 6.9 Hounsfield units (HU) vs. -68.1 +/- 6.7 HU; left circumflex artery (LCX), -62.7 +/- 6.8 HU vs. -65.4 +/- 6.6 HU; and right coronary artery (RCA), -63.6 +/- 8.5 HU vs. -65.5 +/- 7.7 HU (P < 0.01). Multivariate logistic regression analysis, including conventional risk factors, revealed that PCATA per standard deviation in the LAD (odds ratio [OR], 1.449; 95% confidence interval [CI], 1.152-1.823), LCX (OR, 1.634; 95% CI, 1.283-2.081), and RCA (OR, 1.388; 95% CI, 1.107-1.740) were independently associated with HFpEF. The association between PCATA and HFpEF was mostly consistent across various patient clinical characteristics. The left ventricular mass and left atrial volume index showed a mild correlation with LAD-PCATA (rho = 0.13 [P rho = 0.24 [P < 0.01]) and LCX-PCATA (rho = 0.16 [P rho = 0.23 [P < 0.01]).
Conclusions　High PCATA score was significantly associated with the presence of HFpEF. Our results suggest that inflammation in the pericoronary artery adipose tissue is one of the underlying mechanisms of HFpEF. en-copyright= kn-copyright= en-aut-name=NishiharaTakahiro en-aut-sei=Nishihara en-aut-mei=Takahiro 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=NakashimaMitsutaka en-aut-sei=Nakashima en-aut-mei=Mitsutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IchikawaKeishi en-aut-sei=Ichikawa en-aut-mei=Keishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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=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, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Graduate School 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, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Cardiovascular 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 Cardiovascular Medicine, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Adipose tissue kn-keyword=Adipose tissue en-keyword=Computed tomography kn-keyword=Computed tomography en-keyword=Coronary artery kn-keyword=Coronary artery en-keyword=Heart failure kn-keyword=Heart failure en-keyword=Inflammation kn-keyword=Inflammation END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=6 article-no= start-page=e01160 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230523 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pulmonary alveolar proteinosis after lung transplantation: Two case reports and literature review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pulmonary alveolar proteinosis (PAP) affecting transplanted lungs is not well recognized. Herein, we report two cases of PAP after lung transplantation (LTx). The first case was a 4-year-old boy with hereditary pulmonary fibrosis who underwent bilateral LTx and presented with respiratory distress on postoperative day (POD) 23. He was initially treated for acute rejection, died due to infection on POD 248, and was diagnosed with PAP at autopsy. The second case involved a 52-year-old man with idiopathic pulmonary fibrosis who underwent bilateral LTx. On POD 99, chest computed tomography revealed ground-glass opacities. Bronchoalveolar lavage and transbronchial biopsy led to a diagnosis of PAP. Follow-up with immunosuppression tapering resulted in clinical and radiological improvement. PAP after lung transplantation mimics common acute rejection; however, is potentially transient or resolved with tapering immunosuppression, as observed in the second case. Transplant physicians should be aware of this rare complication to avoid misconducting immunosuppressive management. en-copyright= kn-copyright= en-aut-name=KawanaShinichi en-aut-sei=Kawana en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=ShimizuDai en-aut-sei=Shimizu en-aut-mei=Dai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 ORCID= en-aut-name=HattoriNoboru en-aut-sei=Hattori en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Molecular and Internal Medicine, Hiroshima University, Graduate School of Biomedical and Health Sciences kn-affil= affil-num=9 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= en-keyword=graft dysfunction kn-keyword=graft dysfunction en-keyword=immunosuppression kn-keyword=immunosuppression en-keyword=lung transplantation kn-keyword=lung transplantation en-keyword=pulmonary alveolar proteinosis kn-keyword=pulmonary alveolar proteinosis END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=7 article-no= start-page=2300163 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230428 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Particle and Heavy Ion Transport Code System‐Based Microdosimetry for the Development of Boron Agents for Boron Neutron Capture Therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Boron neutron capture therapy (BNCT) is a radiation therapy that selectively kills cancer cells at the cellular level using the boron neutron capture reaction (BNCR) (10B(n.α)7Li). The amount of boron 10B delivers in boronophenylalanine (BPA)-BNCT to achieve anti-tumor effects is ≈15–40 ppm. The same is true for all boron drugs; however, whether the same amount of 10B is required for other boron drugs with different accumulation characteristics has not been intensively investigated. Therefore, herein, a virtual cell model with intracellular organelles is prepared, and the BPA equivalent dose concentration to the cell nucleus is analyzed using particle and heavy ion transport code system-based microdosimetry. Additionally, the intranuclear minimal region (IMR) is set as a reference for the concept of the intranuclear domain in the microdosimetric kinetic model, and the BPA equivalent dose concentration to the IMR is estimated. The required boron delivery dose greatly varies depending on the dose assessment based on the accumulation characteristics of boron agents in intracellular organelles. Evaluation of the BNCR effect according to the accumulation characteristics without being influenced by the specified value of 15–40 ppm is recommended. en-copyright= kn-copyright= en-aut-name=ShigehiraTakafumi en-aut-sei=Shigehira en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HanafusaTadashi en-aut-sei=Hanafusa en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=KasaiTomonari en-aut-sei=Kasai en-aut-mei=Tomonari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FuruyaShuichi en-aut-sei=Furuya en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 ORCID= en-aut-name=MichiueHiroyuki en-aut-sei=Michiue en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujimuraAtsushi en-aut-sei=Fujimura en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Neutron Therapy Research Center, Okayama University kn-affil= affil-num=3 en-affil=Neutron Therapy Research Center, Okayama University kn-affil= affil-num=4 en-affil=Neutron Therapy Research Center, Okayama University kn-affil= affil-num=5 en-affil=Research Laboratory of Accelerator-Based BNCT system, Graduate School of Engineering Nagoya University kn-affil= affil-num=6 en-affil=Department of Hematology and Oncology Okayama University Hospital Okayama Okayama 700–8558 Japan kn-affil= affil-num=7 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Neutron Therapy Research Center, Okayama University kn-affil= affil-num=9 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=boron agents kn-keyword=boron agents en-keyword=boron neutron capture therapy kn-keyword=boron neutron capture therapy en-keyword=simulation study kn-keyword=simulation study END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=5 article-no= start-page=e7119 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Like a shot-through manubrium: A rare presentation of skeletal tuberculosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 22-year-old Vietnamese woman presented with anterior chest swelling.

Manubrium/sternum involvement in tuberculosis is extremely rare but should be considered. en-copyright= kn-copyright= en-aut-name=FujiwaraTomohiro en-aut-sei=Fujiwara en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YanaiHiroyuki en-aut-sei=Yanai en-aut-mei=Hiroyuki 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= 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 Diagnostic Pathology, 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= en-keyword=manubrium kn-keyword=manubrium en-keyword=sternal infection kn-keyword=sternal infection en-keyword=tuberculosis kn-keyword=tuberculosis END start-ver=1.4 cd-journal=joma no-vol=62 cd-vols= no-issue=21 article-no= start-page=e202303391 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=Bifunctional Iminophosphorane‐Catalyzed Enantioselective Nitroalkane Addition to Unactivated α,β‐Unsaturated Esters en-subtitle= kn-subtitle= en-abstract= kn-abstract=Herein we describe the enantioselective intermolecular conjugate addition of nitroalkanes to unactivated α,β-unsaturated esters, catalyzed by a bifunctional iminophosphorane (BIMP) superbase. The transformation provides the most direct access to pharmaceutically relevant enantioenriched γ-nitroesters, utilizing feedstock chemicals, with unprecedented selectivity. The methodology exhibits a broad substrate scope, including β-(fluoro)alkyl, aryl and heteroaryl substituted electrophiles, and was successfully applied on a gram scale with reduced catalyst loading, and, additionally, catalyst recovery was carried out. The formal synthesis of a range of drug molecules, and an enantioselective synthesis of (S)-rolipram were achieved. Additionally, computational studies revealed key reaction intermediates and transition state structures, and provided rationale for high enantioselectivities, in good agreement with experimental results. en-copyright= kn-copyright= en-aut-name=RozsarDaniel en-aut-sei=Rozsar en-aut-mei=Daniel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FarleyAlistair J.

The effect of prehospital advanced life support (ALS), including epinephrine administration or advanced airway, compared with no ALS in this setting remains unclear. This study's objective was to determine the association between any prehospital ALS care and outcomes of patients who received ECPR with emergency medical services-treated OHCA.
Methods: This was a secondary analysis of data from the Study of Advanced Cardiac Life Support for Ventricular Fibrillation with Extracorporeal Circulation in Japan (SAVE-J) II study. Patients were separated into 2 groups-those who received prehospital ALS (ALS group) and those did not receive prehospital ALS (no ALS group). Multiple logistic regression analysis was used to investigate the association between prehospital ALS and favorable neurological outcomes (defined as Cerebral Performance Category scores 1-2) at hospital discharge.
Results: A total of 1289 patients were included, with 644 patients in the ALS group and 645 patients in the no ALS group. There were fewer favorable neurological outcomes at hospital discharge in the ALS group compared with the no ALS group (10.4 vs 19.8%, p <0.001). A multiple logistic regression analysis revealed that any prehospital ALS care (adjusted odds ratios 0.47; 95% confidence interval 0.34-0.66; p <0.001) was associated with unfavorable neurological outcomes at hospital discharge.
Conclusion: Prehospital ALS was associated with worse neurological outcomes at hospital discharge in patients treated with ECPR for OHCA. Further prospective studies are required to determine the clinical implications of these findings. en-copyright= kn-copyright= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya 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=HifumiToru en-aut-sei=Hifumi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueAkihiko en-aut-sei=Inoue en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakamotoTetsuya en-aut-sei=Sakamoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KurodaYasuhiro en-aut-sei=Kuroda en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 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=9 ORCID= en-aut-name=SAVE-J II study group en-aut-sei=SAVE-J II study group en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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 and Critical Care Medicine, St. Luke’s International Hospital kn-affil= affil-num=4 en-affil=Department of Emergency, Disaster and Critical Care Medicine, Hyogo Emergency Medical Center kn-affil= affil-num=5 en-affil=Department of Emergency Medicine, Teikyo University School of Medicine kn-affil= affil-num=6 en-affil=Department of Emergency, Disaster, and Critical Care Medicine, Kagawa University Hospital kn-affil= affil-num=7 en-affil=Department of Epidemiology, 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= affil-num=9 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=1 article-no= start-page=e828 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230314 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Successfully treated case of severe hypothermia secondary to myxedema coma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Myxedema coma is an extremely rare but fatal endocrine emergency that requires urgent recognition and treatment. We describe a case of severe hypothermia that rapidly deteriorated to cardiac arrest that was attributed to myxedema coma.
Case Presentation: A 52-year-old man without a history of hypothyroidism was transferred to our emergency department due to coma and profound hypothermia. The patient developed cardiac arrest immediately after hospital arrival but return of spontaneous circulation was achieved shortly after resuscitation. The patient was noted to have generalized, nonpitting edema, dry skin, severe respiratory acidosis, hyponatremia, and elevated creatinine kinase, which was indicative of hypothyroidism. Myxedema coma was confirmed by a thyroid profile. The patient was successfully treated with intravenous levothyroxine and glucocorticoid.
Conclusion: Although myxedema coma is a rare cause of severe hypothermia, emergency physicians should be familiar with its clinical features and management. en-copyright= kn-copyright= en-aut-name=YamamotoHirotsugu en-aut-sei=Yamamoto en-aut-mei=Hirotsugu 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=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=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KosakiYoshinori en-aut-sei=Kosaki en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AgetaKohei en-aut-sei=Ageta en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei 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= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University 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= affil-num=9 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Cardiac arrest kn-keyword=Cardiac arrest en-keyword=diagnosis kn-keyword=diagnosis en-keyword=hypothermia kn-keyword=hypothermia en-keyword=hypothyroidism kn-keyword=hypothyroidism en-keyword=myxedema coma kn-keyword=myxedema coma 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=20230210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Activated CTLA-4-independent immunosuppression of Treg cells disturbs CTLA-4 blockade-mediated antitumor immunity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Combination therapy with anti-cytotoxic T lymphocyte-associated protein 4 (CTLA-4) and anti-programmed death-1 (PD-1) monoclonal antibodies (mAbs) has dramatically improved the prognosis of patients with multiple types of cancer, including renal cell carcinoma (RCC). However, more than half of RCC patients fail to respond to this therapy. Regulatory T cells (Treg cells) are a subset of highly immunosuppressive CD4(+) T cells that promote the immune escape of tumors by suppressing effector T cells in the tumor microenvironment (TME) through various mechanisms. CTLA-4 is constitutively expressed in Treg cells and is regarded as a key molecule for Treg-cell-mediated immunosuppressive functions, suppressing antigen-presenting cells by binding to CD80/CD86. Reducing Treg cells in the TME with an anti-CTLA-4 mAb with antibody-dependent cellular cytotoxicity (ADCC) activity is considered an essential mechanism to achieve tumor regression. In contrast, we demonstrated that CTLA-4 blockade without ADCC activity enhanced CD28 costimulatory signaling pathways in Treg cells and promoted Treg-cell proliferation in mouse models. CTLA-4 blockade also augmented CTLA-4-independent immunosuppressive functions, including cytokine production, leading to insufficient antitumor effects. Similar results were also observed in human peripheral blood lymphocytes and tumor-infiltrating lymphocytes from patients with RCC. Our findings highlight the importance of Treg-cell depletion to achieve tumor regression in response to CTLA-4 blockade therapies. en-copyright= kn-copyright= en-aut-name=WatanabeTomofumi en-aut-sei=Watanabe en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshinoTakamasa en-aut-sei=Ishino en-aut-mei=Takamasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UedaYouki en-aut-sei=Ueda en-aut-mei=Youki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NagasakiJoji en-aut-sei=Nagasaki en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SadahiraTakuya en-aut-sei=Sadahira en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DansakoHiromichi en-aut-sei=Dansako en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=TogashiYosuke en-aut-sei=Togashi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Urology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Urology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=antibody-dependent cell cytotoxicity kn-keyword=antibody-dependent cell cytotoxicity en-keyword=cytotoxic T-lymphocyte-associated antigen 4 kn-keyword=cytotoxic T-lymphocyte-associated antigen 4 en-keyword=immune checkpoint inhibitors kn-keyword=immune checkpoint inhibitors en-keyword=regulatory T cell kn-keyword=regulatory T cell en-keyword=renal cell carcinoma kn-keyword=renal cell carcinoma END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=1 article-no= start-page=e829 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230323 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Influence of coronavirus disease 2019 case surges on prehospital emergency medical service for patients with trauma in Kobe, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim: In the current era of the coronavirus disease 2019 (COVID-19) pandemic, the responsiveness of emergency medical service (EMS) transport for patients with internal illness is often delayed. However, the influence of the COVID-19 pandemic on prehospital transport for patients with trauma has not yet been fully elucidated. This study aims to examine the effect of COVID-19 case surges on EMS transport for patients with trauma during the COVID-19 states of emergency in Kobe, Japan.
Methods: EMS data during the states of emergency were compared with those in the 2019 prepandemic period. The incidence of difficulty securing hospital acceptance (four or more calls to medical institutions and ambulance staying at the scene for 30 min or more) was evaluated as a primary outcome. Secondary outcomes were the time spent at the trauma scene and the number of calls requesting hospital acceptance. The time spent at the trauma scene was stratified by trauma severity.
Results: The incidence of difficulty securing hospital acceptance increased (1.2% versus 3.2%, P < 0.01). Logistic regression analysis revealed that the duration of the states of emergency was associated with difficulty securing hospital acceptance (odds ratio [OR] 2.08, 95% confidence interval 1.77-2.45; P < 0.01). Although the mean time spent at the trauma scene among the less severe, moderately severe, and severe trauma groups was prolonged, the time for the life-threatening group did not change. The number of request calls increased during the states of emergency.
Conclusion: Difficulty securing hospital acceptance increased; however, the time spent at the trauma scene did not significantly change for the life-threatening group. en-copyright= kn-copyright= en-aut-name=NishimuraTakeshi en-aut-sei=Nishimura en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugaMasafumi en-aut-sei=Suga en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshiharaSatoshi en-aut-sei=Ishihara en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakayamaShinichi en-aut-sei=Nakayama en-aut-mei=Shinichi 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=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Emergency and Critical Care Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Emergency and Critical Care Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Emergency and Critical Care Medicine, Hyogo Emergency Medical Center kn-affil= affil-num=4 en-affil=Department of Emergency and Critical Care Medicine, Hyogo Emergency Medical Center kn-affil= affil-num=5 en-affil=Department of Emergency and Critical Care Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Emergency and Critical Care Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Coronavirus kn-keyword=Coronavirus en-keyword=EMS kn-keyword=EMS en-keyword=prehospital time kn-keyword=prehospital time en-keyword=severity kn-keyword=severity en-keyword=state of emergency kn-keyword=state of emergency END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=1 article-no= start-page=e06865 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230116 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tuberculous meningitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tuberculous meningitis is possibly complicated with multiple cerebral infarctions and basal meningitis, and the mortality and neurological prognosis is reportedly poor.

Here, it is reported that, contrary to the initial aim, a tRNA-modifying methylthiotransferase CDKAL1 promotes CSC-factor SALL2 synthesis by assembling the eIF4F translation initiation complex. CDKAL1 expression is upregulated in patients with worse prognoses and is essential for maintaining CSCs in rhabdomyosarcoma (RMS) and common cancers. Translatome analysis reveals that a group of mRNAs whose translation is CDKAL1-dependent contains cytosine-rich sequences in the 5' untranslated region (5'UTR). Mechanistically, CDKAL1 promotes the translation of such mRNAs by organizing the eIF4F translation initiation complex. This complex formation does not require the enzyme activity of CDKAL1 but requires only the NH2-terminus domain of CDKAL1. Furthermore, sites in CDKAL1 essential for forming the eIF4F complex are identified and discovered candidate inhibitors of CDKAL1-dependent translation. en-copyright= kn-copyright= en-aut-name=HuangRongsheng en-aut-sei=Huang en-aut-mei=Rongsheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoTakahiro en-aut-sei=Yamamoto en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WeiFanyan en-aut-sei=Wei en-aut-mei=Fanyan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TomizawaKazuhito en-aut-sei=Tomizawa en-aut-mei=Kazuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujimuraAtsushi en-aut-sei=Fujimura en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Cellular Physiology Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Molecular Physiology Kumamoto University Faculty of Life Sciences Kumamoto kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurosurgery Hamamatsu University School of Medicine Hamamatsu kn-affil= affil-num=6 en-affil=Department of Modomics Biology and Medicine Institute of Development, Aging and Cancer Tohoku University kn-affil= affil-num=7 en-affil=Department of Molecular Physiology Kumamoto University Faculty of Life Sciences Kumamoto kn-affil= affil-num=8 en-affil=Department of Cellular Physiology Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=cancer stem-like cells kn-keyword=cancer stem-like cells en-keyword=CG-rich 5'UTR kn-keyword=CG-rich 5'UTR en-keyword=eIF4F complex kn-keyword=eIF4F complex en-keyword=CDKAL1 kn-keyword=CDKAL1 en-keyword=SALL2 kn-keyword=SALL2 END start-ver=1.4 cd-journal=joma no-vol=35 cd-vols= no-issue=4 article-no= start-page=430 end-page=442 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221213 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Endoscopic ablation therapy for the pancreatic neoplasms en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recently, endoscopic ultrasound (EUS)-guided ablation therapy has been reported as a less invasive therapy for patients with pancreatic neoplasms. Some ablation techniques, including injective ablation (using ethanol or other ablative agents), radiofrequency ablation (RFA), photodynamic therapy, and laser ablation, have been described in the literature. Among these, injective ablation and RFA are more frequently used for treating pancreatic neoplasms. Few studies have evaluated the effectiveness of EUS-guided ethanol ablation (EUS-EA) for potentially malignant solid neoplasms (neuroendocrine neoplasms or solid pseudopapillary neoplasms) and have reported a complete response (CR) rate of 60-80%. In addition, the CR rate after EUS-RFA for these lesions has been reported to be 55-100%, with no additional procedure-related adverse events (AEs). Regarding the amelioration of the symptoms of an insulinoma, the success rates of both the therapies were found to be excellent. Regarding complete tumor ablation, EUS-RFA appeared to be superior to EUS-EA. Although EUS-RFA has been reported as a safe treatment for pancreatic cancers, its effectiveness remains inadequate. Some studies have examined the effectiveness of EUS-guided injection ablation therapy for pancreatic cystic neoplasms (PCNs) and have reported CR rates that range from 35% to 79%. Alcohol-free chemotherapeutic agent ablation appears to be effective, with a low risk of AEs. However, studies on the effectiveness of EUS-RFA for PCNs are limited. In the future, EUS-guided ablation therapy could become a more widely used approach for potentially malignant and malignant pancreatic lesions. en-copyright= kn-copyright= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki 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= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= en-keyword=ablation techniques kn-keyword=ablation techniques en-keyword=endoscopic ultrasonography kn-keyword=endoscopic ultrasonography en-keyword=ethanol kn-keyword=ethanol en-keyword=pancreatic neoplasms kn-keyword=pancreatic neoplasms en-keyword=radiofrequency ablation kn-keyword=radiofrequency ablation 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=10 cd-vols= no-issue=11 article-no= start-page=e06652 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Isolated unilateral absence of adult pulmonary artery en-subtitle= kn-subtitle= en-abstract= kn-abstract=Isolated unilateral absence of pulmonary artery (UAPA) is a rare congenital malformation.

To examine the relationship between the number of present and functional teeth at baseline and future incidence of loss of independence.

Methods
Participants were community-dwelling older individuals who participated in a comprehensive geriatric health examination conducted in Kusatsu town, Japan, between 2009 and 2015. The primary endpoint was the incidence of loss of independence among participants, defined as the first certification of long-term care insurance in Japan. The numbers of present and functional teeth at baseline were determined via an oral examination. Demographics, clinical variables (e.g., history of chronic diseases and psychosocial factors), blood nutritional markers, physical functions, and perceived masticatory function were assessed.

Results
This study included 1121 individuals, and 205 individuals suffered from loss of independence during the follow-up period. Kaplan–Meier estimates of loss of independence for participants with smaller numbers of present and functional teeth were significantly greater than for those with larger numbers of teeth. Cox proportional hazard analyses indicated that a smaller number of present teeth was not a significant risk factor after adjusting for demographic characteristics. However, the number of functional teeth was a significant risk factor after the adjustment (hazard ratio: 1.975 [1.168–3.340]). Additionally, higher hazard ratios were observed in other adjusted models, but they were not statistically significant.

Conclusions
The number of functional teeth may be more closely related to the future incidence of loss of independence than the number of present teeth. This novel finding suggests that prosthodontic rehabilitation for tooth loss possibly prevents the future incidence of this life-event. en-copyright= kn-copyright= en-aut-name=MaekawaKenji

dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Resistance to immune checkpoint inhibitors and the tumor microenvironment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immune checkpoint inhibitors (ICIs) have contributed significantly to the treatment of various types of cancer, including skin cancer. However, not all patients respond; some patients do not respond at all (primary resistance), while others experience recurrence after the initial response (acquired resistance). Therefore, overcoming ICI resistance is an urgent priority. Numerous ICI resistance mechanisms have been reported. They are seemingly quite complex, varying from patient to patient. However, most involve T cell activation processes, especially in the tumor microenvironment (TME). ICIs exert their effects in the TME by reactivating suppressed T cells through inhibition of immune checkpoint molecules, such as cytotoxic T-lymphocyte antigen-4 (CTLA-4) and programmed cell death protein 1 (PD-1). Thus, this review focuses on the resistance mechanisms based on the T cell activation process. Here, we classify the main mechanisms of ICI resistance into three categories based on: (1) antigen recognition, (2) T cell migration and infiltration, and (3) effector functions of T cells.

Lymphadenectomy is crucial for accurate staging and hopes of possible oncological treatment. However, the therapeutic implications and optimal extent of lymphadenectomy remain contentious. Methods To clarify the prognostic value and optimal extent of lymphadenectomy, the therapeutic index (TI) for each lymph node was analyzed for 279 cases that had undergone lymphadenectomy in a multi-institutional database. Tumor localization was divided into hilar lesions (n = 130), right peripheral lesions (n = 60), and left peripheral lesions (n = 89). In addition, the lymph node station was classified as Level 1 (LV1: hepatoduodenal ligament node), Level 2 (LV2: postpancreatic or common hepatic artery nodes), or Level 3 (LV3: gastrocardiac, left gastric artery, or celiac artery nodes). Results Lymph node metastases were confirmed in 109 patients (39%). Five-y survival rates were 45.3% for N0 disease, 27.1% for LV1-LNM, 22.9% for LV2-LNM, and 7.3% for LV3-LNM (P < 0.001). LV3-LNM were the most frequent and earliest recurrence outcome, including multisite recurrence, followed by LV2, LV1, and N0 disease. The 5-year TI (5year-TI) for lymphadenectomy was 7.2 for LV1, 5.5 for LV2, and 1.9 for LV3. Regarding tumor location, hilar lesions showed 5-year TI > 5.0 in LV1 and LV2, whereas bilateral peripheral lesions showed 5-year TI > 5.0 in LV1. Conclusion The implications and extent of lymphadenectomy for ICC appear to rely on tumor location. In the peripheral type, the benefit of lymphadenectomy would be limited and dissection beyond LV1 should be avoided, while in the hilar type, lymphadenectomy up to LV2 could be recommended. en-copyright= kn-copyright= en-aut-name=UmedaYuzo en-aut-sei=Umeda en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsudaTatsuo en-aut-sei=Matsuda en-aut-mei=Tatsuo 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=KojimaToru en-aut-sei=Kojima en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SatohDaisuke en-aut-sei=Satoh en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 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=9 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=10 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=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, 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 Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Surgery, Okayama Saiseikai General Hospital kn-affil= affil-num=6 en-affil=Department of Surgery, Hiroshima Citizens Hospital kn-affil= affil-num=7 en-affil=Department of Surgery, Fukuyama City Hospital kn-affil= affil-num=8 en-affil=Department of Surgery, Himeji Red Cross Hospital kn-affil= affil-num=9 en-affil=Department of Surgery, National Hospital Organization Fukuyama Medical Center kn-affil= affil-num=10 en-affil=Department of Surgery, Tottori Municipal Hospital 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= en-keyword=intrahepatic cholangiocarcinoma kn-keyword=intrahepatic cholangiocarcinoma en-keyword=lymphadenectomy kn-keyword=lymphadenectomy en-keyword=multicenter study kn-keyword=multicenter study en-keyword=retrospective study kn-keyword=retrospective study END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue= article-no= start-page=e13817 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221124 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Validation of pencil beam scanning proton therapy with multi-leaf collimator calculated by a commercial Monte Carlo dose engine en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to evaluate the clinical beam commissioning results and lateral penumbra characteristics of our new pencil beam scanning (PBS) proton therapy using a multi-leaf collimator (MLC) calculated by use of a commercial Monte Carlo dose engine. Eighteen collimated uniform dose plans for cubic targets were optimized by the RayStation 9A treatment planning system (TPS), varying scan area, modulation widths, measurement depths, and collimator angles. To test the patient-specific measurements, we also created and verified five clinically realistic PBS plans with the MLC, such as the liver, prostate, base-of-skull, C-shape, and head-and-neck. The verification measurements consist of the depth dose (DD), lateral profile (LP), and absolute dose (AD). We compared the LPs and ADs between the calculation and measurements. For the cubic plans, the gamma index pass rates (gamma-passing) were on average 96.5% +/- 4.0% at 3%/3 mm for the DD and 95.2% +/- 7.6% at 2%/2 mm for the LP. In several LP measurements less than 75 mm depths, the gamma-passing deteriorated (increased the measured doses) by less than 90% with the scattering such as the MLC edge and range shifter. The deteriorated gamma-passing was satisfied by more than 90% at 2%/2 mm using uncollimated beams instead of collimated beams except for three planes. The AD differences and the lateral penumbra width (80%-20% distance) were within +/- 1.9% and +/- 1.1 mm, respectively. For the clinical plan measurements, the gamma-passing of LP at 2%/2 mm and the AD differences were 97.7% +/- 4.2% on average and within +/- 1.8%, respectively. The measurements were in good agreement with the calculations of both the cubic and clinical plans inserted in the MLC except for LPs less than 75 mm regions of some cubic and clinical plans. The calculation errors in collimated beams can be mitigated by substituting uncollimated beams. en-copyright= kn-copyright= en-aut-name=TominagaYuki en-aut-sei=Tominaga en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakuraiYusuke en-aut-sei=Sakurai en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyataJunya en-aut-sei=Miyata en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HaradaShuichi en-aut-sei=Harada en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AkagiTakashi en-aut-sei=Akagi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OitaMasataka en-aut-sei=Oita en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Division of Radiological Technology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiotherapy, Medical Co.

en-abstract= kn-abstract=Aim Sexually transmitted infections remain a neglected area of research in geriatrics. However, in the global aging societies, sexual health among the middle-aged and older adults is an emerging public concern. High-income countries are facing a resurgence of syphilis cases among young generations, but little is known about its prevalence in older populations. We aimed to investigate the national trend of syphilis cases in Japan. Methods This nationwide observational study used the publicly-available database (2009-2019) to calculate crude and age-adjusted incidence rates of syphilis per 100 000 population by age, sex and clinical stage. We collected data from patients aged >= 50 years and performed joinpoint regression analysis to estimate long-term trends and average annual percentage changes (AAPCs). Results The total number of patients with syphilis increased about 8-fold from 165 in 2009 to 1280 in 2019. AAPCs of crude incidence rates significantly increased in every age category; 33.2% in 50-59 years, 23.8% in 60-69 years and 20.9% in >= 70 years. Age-adjusted incidence rates have surged at AAPCs of 28.7% in men and 23.1% in women, reaching 4.09 in men and 0.71 in women in 2019. By clinical stage, marked increases were observed in primary (AAPCs, 42.3% in men and 41.6% in women) and secondary syphilis (AAPCs, 24.9% in men and 24.2% in women). Conclusions An up-toward trend of syphilis among people aged >= 50 years was observed. The importance of sexual health among older people should be highlighted in this aging Japanese society.

While affected male patients with ALD present severe neurological symptoms, some female carriers slowly develop spastic gait and urinary incontinence. We report a case of a symptomatic female ALD carrier with a novel ABCD1 gene mutation. She has developed progressive gait disturbance since age 40, and her father and sister had similar symptoms. When admitted to our hospital at age 66, blood analysis showed slight increase of VLCFA, and DNA analysis of ABCD1 gene revealed a novel heterozygous missense mutation (c.1700 A>C, p.Gln567Pro). The genetic testing for ABCD1 gene can be considered in female patients over middle age presenting spastic gait, because female ALD carriers tend to be symptomatic beyond age 60. en-copyright= kn-copyright= en-aut-name=NakanoYumiko en-aut-sei=Nakano en-aut-mei=Yumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TairaYuki en-aut-sei=Taira en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SasakiRyo en-aut-sei=Sasaki en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TadokoroKoh en-aut-sei=Tadokoro en-aut-mei=Koh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YunokiTaijun en-aut-sei=Yunoki en-aut-mei=Taijun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NomuraEmi en-aut-sei=Nomura en-aut-mei=Emi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FukuiYusuke en-aut-sei=Fukui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakemotoMami en-aut-sei=Takemoto en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoriharaRyuta en-aut-sei=Morihara en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ShimozawaNobuyuki en-aut-sei=Shimozawa en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= affil-num=1 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Division of Genomics Research, Life Science Research Center, Gifu university kn-affil= affil-num=11 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=adrenoleukodystrophy kn-keyword=adrenoleukodystrophy en-keyword=symptomatic female carriers kn-keyword=symptomatic female carriers en-keyword=spastic paraplegia kn-keyword=spastic paraplegia en-keyword=ABCD1 kn-keyword=ABCD1 END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=2 article-no= start-page=205 end-page=220 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=Suramin prevents the development of diabetic kidney disease by inhibiting NLRP3 inflammasome activation in KK-Ay mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims/Introduction Nucleotide-binding oligomerization domain-like receptor family pyrin domain containing 3 (NLRP3) inflammasomes produce IL-18 upon being activated by various stimuli via the P2 receptors. Previously, we showed that serum and urine IL-18 levels are positively associated with albuminuria in patients with type 2 diabetes, indicating the involvement of inflammasome activation in the pathogenesis of diabetic kidney disease (DKD). In the present study, we investigated whether the administration of suramin, a nonselective antagonist of the P2 receptors, protects diabetic KK.Cg-A(y)/TaJcl (KK-Ay) mice against DKD progression. Materials and Methods Suramin or saline was administered i.p. to KK-Ay and C57BL/6J mice once every 2 weeks for a period of 8 weeks. Mouse mesangial cells (MMCs) were stimulated with ATP in the presence or absence of suramin. Results Suramin treatment significantly suppressed the increase in the urinary albumin-to-creatinine ratio, glomerular hypertrophy, mesangial matrix expansion, and glomerular fibrosis in KK-Ay mice. Suramin also suppressed the upregulation of NLRP3 inflammasome-related genes and proteins in the renal cortex of KK-Ay mice. P2X4 and P2X7 receptors were significantly upregulated in the isolated glomeruli of KK-Ay mice and mainly distributed in the glomerular mesangial cells of KK-Ay mice. Although neither ATP nor suramin affected NLRP3 expression in MMCs, suramin inhibited ATP-induced NLRP3 complex formation and the downstream expression of caspase-1 and IL-18 in MMCs. Conclusions These results suggest that the NLRP3 inflammasome is activated in a diabetic kidney and that inhibition of the NLRP3 inflammasome with suramin protects against the progression of early stage DKD. en-copyright= kn-copyright= en-aut-name=OdaKaori en-aut-sei=Oda en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyamotoSatoshi en-aut-sei=Miyamoto en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KoderaRyo en-aut-sei=Kodera en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=ShikataKenichi en-aut-sei=Shikata en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Osafune Clinic kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism kn-affil= affil-num=5 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= en-keyword=Diabetic kidney disease kn-keyword=Diabetic kidney disease en-keyword=Inflammasomes kn-keyword=Inflammasomes en-keyword=Suramin kn-keyword=Suramin 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=202210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Commodity momentum decomposition en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study decomposes the momentum factor (MOM) in the commodity futures market.

The positive returns on MOM and PTH are associated with overconfidence and strong self-attribution. In contrast, HTP is linked to investors’ underreaction and the information diffusion process. Moreover, we find that positive demand shocks raise the return on HTP. en-copyright= kn-copyright= en-aut-name=IwanagaYasuhiro en-aut-sei=Iwanaga en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakemotoRyuta en-aut-sei=Sakemoto en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=The Faculty of Economic Sciences Hiroshima Shudo University kn-affil= affil-num=2 en-affil=Faculty of Humanities and Social Sciences Okayama University kn-affil= en-keyword=commodity futures kn-keyword=commodity futures en-keyword=decomposition kn-keyword=decomposition en-keyword=momentum kn-keyword=momentum END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=12 article-no= start-page=1300 end-page=1307 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy of intraductal placement of non‐flared fully‐covered metal stent for refractory perihilar benign biliary strictures: A multicenter prospective study with long‐term observation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Endoscopic fully-covered self-expandable metal stents (FCSEMSs) are used to treat benign biliary strictures (BBSs); however, treatment for perihilar BBSs is technically challenging. The aim of this study was to evaluate the usefulness of an unflared FCSEMS designed for intraductal placement in patients with refractory perihilar BBS.
Methods: Twenty-two consecutive patients with perihilar BBS unresolved by endoscopic plastic stent placement at 13 tertiary medical centers were prospectively enrolled. The FCSEMS was placed above the papilla and removed after 4 months. The primary outcome was stricture resolution at 4 months, and the secondary outcomes were technical success, stent removal, adverse events, and recurrence.
Results: The technical success rate of intraductal FCSEMS placement was 100%, and plastic stent placement at contralateral or side branch was performed in 86% of patients. The rate of successful stent removal at 4 months was 100%, and stricture resolution was observed in 91% of patients. Stent migration or stent-induced de novo stricture did not occur in any patient. The stricture recurrence rate was 16%, and the median (interquartile range) follow-up duration was 2.8 (1.6-3.3) years.
Conclusions: Intraductal placement of unflared FCSEMS is effective treatment for refractory perihilar BBS. en-copyright= kn-copyright= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki 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=FujiiMasakuni en-aut-sei=Fujii en-aut-mei=Masakuni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UekiToru en-aut-sei=Ueki en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 ORCID= en-aut-name=MannamiTomohiko en-aut-sei=Mannami en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Internal Medicine Okayama Saiseikai General Hospital kn-affil= affil-num=4 en-affil=Departments of Internal Medicine, Fukuyama City Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology, Iwakuni Medical Center kn-affil= affil-num=6 en-affil=Department of Gastroenterology, Tsuyama Central Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology, National Hospital Organization Okayama Medical Center kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology Okayama University Hospital kn-affil= en-keyword=benign biliary stricture kn-keyword=benign biliary stricture en-keyword=fully-covered self-expandable metal stent kn-keyword=fully-covered self-expandable metal stent en-keyword=intraductal placement kn-keyword=intraductal placement en-keyword=refractory biliary stricture kn-keyword=refractory biliary stricture END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=1 article-no= start-page=e786 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220916 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prehospital advanced airway management of emergency medical service-witnessed traumatic out-of-hospital cardiac arrest patients: analysis of nationwide trauma registry en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim: Survival of traumatic out-of-hospital cardiac arrest (OHCA) is poor. Early use of advanced airway management (AAM) tech niques, including endotracheal intubation and supraglottic devices, are expected to contribute to the improved survival of these patients. The aim of this study was to determine whether prehospital use of AAM improves the outcomes for emergency medical service (EMS)-witnessed traumatic OHCA. Methods: A nationwide retrospective study was carried out. Trauma patients with EMS-witnessed cardiac arrest who received car diopulmonary resuscitation during transport were included. Patients younger than 16 years and those with missing data were excluded. We compared two groups using propensity score matching. The primary outcome was survival to discharge. The secondary outcome was return of spontaneous circulation (ROSC) on hospital arrival. A logistic regression model was used to calculate odds ratios (OR) and confidence intervals (CI). Results: After propensity score matching, 1,346 patients were enrolled (AAM 673 versus non-AAM 673). Forty-four AAM cases (6.5%) and 39 non-AAM cases (5.8%) survived. Logistic regression analysis did not show a contribution of AAM for survival to discharge (AAM 44/673 (6.5%), non-AAM 39/673 (5.8%); OR 1.12; 95% CI, 0.70-1.76; P = 0.64). However, AAM improved ROSC on admission (AAM 141/673 (21.0%), non-AAM 77/673 (11.4%); OR 2.05; 95% CI, 1.51-2.78; P < 0.001). This tendency was consistent throughout our subgroup analysis categorized by body region of the severe injury (head trauma, torso trauma, and extremity/spine trauma). Conclusions: Prehospital AAM among EMS-witnessed traumatic OHCA patients was not associated with survival to discharge; however, ROSC on hospital admission improved for the AAM patients. en-copyright= kn-copyright= en-aut-name=NishimuraTakeshi en-aut-sei=Nishimura en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugaMasafumi en-aut-sei=Suga en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=IshiharaSatoshi en-aut-sei=Ishihara en-aut-mei=Satoshi 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 and Critical Care Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Emergency and Critical Care Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Emergency and Critical Care Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Emergency and Critical Care Medicine, Hyogo Emergency Medical Center kn-affil= affil-num=5 en-affil=Department of Emergency and Critical Care Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=AAM kn-keyword=AAM en-keyword=Endotracheal intubation kn-keyword=Endotracheal intubation en-keyword=JTDB kn-keyword=JTDB en-keyword=supraglottic airway kn-keyword=supraglottic airway en-keyword=traumatic cardiac arrest kn-keyword=traumatic cardiac arrest END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue=11 article-no= start-page=3322 end-page=3337 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220907 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=FE UPTAKE‐INDUCING PEPTIDE1 maintains Fe translocation by controlling Fe deficiency response genes in the vascular tissue of Arabidopsis en-subtitle= kn-subtitle= en-abstract= kn-abstract=FE UPTAKE-INDUCING PEPTIDE1 (FEP1), also named IRON MAN3 (IMA3) is a short peptide involved in the iron deficiency response in Arabidopsis thaliana. Recent studies uncovered its molecular function, but its physiological function in the systemic Fe response is not fully understood. To explore the physiological function of FEP1 in iron homoeostasis, we performed a transcriptome analysis using the FEP1 loss-of-function mutant fep1-1 and a transgenic line with oestrogen-inducible expression of FEP1. We determined that FEP1 specifically regulates several iron deficiency-responsive genes, indicating that FEP1 participates in iron translocation rather than iron uptake in roots. The iron concentration in xylem sap under iron-deficient conditions was lower in the fep1-1 mutant and higher in FEP1-induced transgenic plants compared with the wild type (WT). Perls staining revealed a greater accumulation of iron in the cortex of fep1-1 roots than in the WT root cortex, although total iron levels in roots were comparable in the two genotypes. Moreover, the fep1-1 mutation partially suppressed the iron overaccumulation phenotype in the leaves of the oligopeptide transporter3-2 (opt3-2) mutant. These data suggest that FEP1 plays a pivotal role in iron movement and in maintaining the iron quota in vascular tissues in Arabidopsis. en-copyright= kn-copyright= en-aut-name=OkadaSatoshi en-aut-sei=Okada en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LeiGui J. en-aut-sei=Lei en-aut-mei=Gui J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamajiNaoki en-aut-sei=Yamaji en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HuangSheng en-aut-sei=Huang en-aut-mei=Sheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaJian F. en-aut-sei=Ma en-aut-mei=Jian F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=HirayamaTakashi en-aut-sei=Hirayama en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Group of Environmental Stress Response Systems, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Group of Plant Stress Physiology, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Group of Plant Stress Physiology, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Group of Plant Stress Physiology, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Group of Plant Stress Physiology, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Crop Design Research Team, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=Group of Environmental Stress Response Systems, Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=oestrogen induction system kn-keyword=oestrogen induction system en-keyword=fep1-1 kn-keyword=fep1-1 en-keyword=iron-deficiency response kn-keyword=iron-deficiency response en-keyword=transcriptome kn-keyword=transcriptome END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=5 article-no= start-page=266 end-page=268 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220815 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Japanese case of Charcot–Marie–Tooth disease type 2Z with severe retinitis pigmentosa en-subtitle= kn-subtitle= en-abstract= kn-abstract=Charcot-Marie-Tooth disease type 2Z (CMT2Z) shows highly variable clinical features.

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.

and its mutant, acl5, exhibits a dwarf phenotype with excessive xylem formation. Studies of suppressor mutants of acl5 reveal the involvement of thermospermine in enhancing mRNA translation of the SAC51 gene family. We show here that a mutant, sac59, which partially suppresses the acl5 phenotype, has a point mutation in JMJ22 encoding a D6-class Jumonji C protein (JMJD6). A T-DNA insertion allele, jmj22-2, also partially suppressed the acl5 phenotype while mutants of its closest two homologs JMJ21 and JMJ20 had no such effects, suggesting a unique role for JMJ22 in plant development. We found that mRNAs of the SAC51 family are more stabilized in acl5 jmj22-2 than in acl5. en-copyright= kn-copyright= en-aut-name=MatsuoHirotoshi en-aut-sei=Matsuo en-aut-mei=Hirotoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukushimaHiroko en-aut-sei=Fukushima en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurokawaShinpei en-aut-sei=Kurokawa en-aut-mei=Shinpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawanoEri en-aut-sei=Kawano en-aut-mei=Eri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkamotoTakashi en-aut-sei=Okamoto en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MotoseHiroyasu en-aut-sei=Motose en-aut-mei=Hiroyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakahashiTaku en-aut-sei=Takahashi en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, 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=Graduate School of Natural Science and Technology, 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=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Arabidopsis kn-keyword=Arabidopsis en-keyword=JMJD6 kn-keyword=JMJD6 en-keyword=mRNA stability kn-keyword=mRNA stability en-keyword=thermospermine kn-keyword=thermospermine en-keyword=xylem development kn-keyword=xylem development 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=20220724 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Drug repositioning of tranilast to sensitize a cancer therapy by targeting cancer-associated fibroblast en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cancer-associated fibroblasts (CAFs) are a major component of the tumor microenvironment that mediate resistance of cancer cells to anticancer drugs. Tranilast is an antiallergic drug that suppresses the release of cytokines from various inflammatory cells. In this study, we investigated the inhibitory effect of tranilast on the interactions between non-small cell lung cancer (NSCLC) cells and the CAFs in the tumor microenvironment. Three EGFR-mutant NSCLC cell lines, two KRAS-mutant cell lines, and three CAFs derived from NSCLC patients were used. To mimic the tumor microenvironment, the NSCLC cells were cocultured with the CAFs in vitro, and the molecular profiles and sensitivity to molecular targeted therapy were assessed. Crosstalk between NSCLC cells and CAFs induced multiple biological effects on the NSCLC cells both in vivo and in vitro, including activation of the STAT3 signaling pathway, promotion of xenograft tumor growth, induction of epithelial-mesenchymal transition (EMT), and acquisition of resistance to molecular-targeted therapy, including EGFR-mutant NSCLC cells to osimertinib and of KRAS-mutant NSCLC cells to selumetinib. Treatment with tranilast led to inhibition of IL-6 secretion from the CAFs, which, in turn, resulted in inhibition of CAF-induced phospho-STAT3 upregulation. Tranilast also inhibited CAF-induced EMT in the NSCLC cells. Finally, combined administration of tranilast with molecular-targeted therapy reversed the CAF-mediated resistance of the NSCLC cells to the molecular-targeted drugs, both in vitro and in vivo. Our results showed that combined administration of tranilast with molecular-targeted therapy is a possible new treatment strategy to overcome drug resistance caused by cancer-CAF interaction.

kn-subject= en-title= kn-title=Mechanisms of resistance to immune checkpoint inhibitors en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immune checkpoint inhibitors (ICIs) are effective for various types of cancer, and their application has led to paradigm shifts in cancer treatment. While many patients can obtain clinical benefits from ICI treatment, a large number of patients are primarily resistant to such treatment or acquire resistance after an initial response. Thus, elucidating the resistance mechanisms is warranted to improve the clinical outcomes of ICI treatment. ICIs exert their antitumor effects by activating T cells in the tumor microenvironment. There are various resistance mechanisms, such as insufficient antigen recognition by T cells, impaired T-cell migration and/or infiltration, and reduced T-cell cytotoxicity, most of which are related to the T-cell activation process. Thus, we classify them into three main mechanisms: resistance mechanisms related to antigen recognition, T-cell migration and/or infiltration, and effector functions of T cells. In this review, we summarize these mechanisms of resistance to ICIs related to the T-cell activation process and progress in the development of novel therapies that can overcome resistance. en-copyright= kn-copyright= en-aut-name=NagasakiJoji en-aut-sei=Nagasaki en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshinoTakamasa en-aut-sei=Ishino en-aut-mei=Takamasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TogashiYosuke en-aut-sei=Togashi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=cancer immunology kn-keyword=cancer immunology en-keyword=exhaustion kn-keyword=exhaustion en-keyword=immune checkpoint inhibitor kn-keyword=immune checkpoint inhibitor en-keyword=resistance kn-keyword=resistance en-keyword=T cell kn-keyword=T cell END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=7 article-no= start-page=e06028 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220718 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lotus root-like appearance in the left anterior descending artery treated with a drug-coated balloon angioplasty en-subtitle= kn-subtitle= en-abstract= kn-abstract=A lotus root-like appearance of the coronary artery diagnosed by optical coherence tomography (OCT) is characterized by old coronary thrombi that form small lumen channels.

A practical simulation model is desired since it is an invasive technique with higher risks of complications such as bleeding. We developed a simple simulation tool for ultrasound-guided renal biopsy using boiled eggs. Boiled chicken eggs were embedded in the agar, and a biopsy simulation was performed using a real-time ultrasound-guided technique as the renal biopsy simulator by trainees and biopsyproficient nephrologists, and the feedback from the participants was obtained. The ultrasonographic evaluation revealed a clear contrast between egg yolk and white, which clearly mimicked the kidney cortex and medulla region. In addition, we observed the needle entering the egg white under needle penetration, and we obtained the biopsy core consisting of egg white. As for the simulations, all the participants succeeded in obtaining the appropriate samples. A total of 92% of the trainees agreed that the simulation could reduce their fears of performing renal biopsies in patients. In addition, all the trainees and biopsy-proficient nephrologists recommend using the simulator for trainees before conducting renal biopsies on patients. The total cost of the simulator was low (< USD 1/simulator). Collectively, our simulation tool using boiled eggs may be a good candidate for practical simulation models of renal biopsy. en-copyright= kn-copyright= en-aut-name=TsujiKenji en-aut-sei=Tsuji en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 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=4 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama Japan kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama Japan kn-affil= affil-num=3 en-affil=Department of Chronic Kidney Disease and Cardiovascular Disease Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama Japan kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama Japan kn-affil= en-keyword=Renal biopsy kn-keyword=Renal biopsy en-keyword=clinical nephrology kn-keyword=clinical nephrology en-keyword=ultrasound kn-keyword=ultrasound END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=5 article-no= start-page=255 end-page=258 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220615 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Japanese case of successful surgical resection of cerebral cavernous malformations with a CCM2 mutation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cerebral cavernous malformations (CCMs) are congenital abnormalities of cerebral vessels.

Herein, we report a Japanese patient with a CCM2 mutation, c.609G>A (p.K203K) substitution, who showed drug-resistant epilepsy and dramatic improvement after surgical resection. en-copyright= kn-copyright= en-aut-name=NomuraEmi en-aut-sei=Nomura en-aut-mei=Emi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OmoteYoshio en-aut-sei=Omote en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakemotoMami en-aut-sei=Takemoto en-aut-mei=Mami 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=NakanoYumiko en-aut-sei=Nakano en-aut-mei=Yumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YunokiTaijun en-aut-sei=Yunoki en-aut-mei=Taijun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MoriharaRyuta en-aut-sei=Morihara en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=AkagawaHiroyuki en-aut-sei=Akagawa en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=11 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=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Tokyo Women's Medical University Institute for Integrated Medical Sciences kn-affil= affil-num=10 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences Okayama University kn-affil= en-keyword=CCM2 kn-keyword=CCM2 en-keyword=cerebral cavernous malformation kn-keyword=cerebral cavernous malformation en-keyword=drug-resistant epilepsy kn-keyword=drug-resistant epilepsy END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=8 article-no= start-page=675 end-page=680 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220623 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Trends in places and causes of death among centenarians in Japan from 2006 to 2016 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim
Amid the global aging, an establishment of healthcare policies for the aged population is a common issue to be addressed. However, few studies on centenarians have reported place and cause of death (PoD and CoD, respectively) as indicators of end-of-life care quality. This study aimed to analyze trends in PoD and CoD among centenarians in Japan.

Methods
Data from death certificates from Japanese vital statistics were analyzed; 205 513 deaths occurred among centenarians (aged ≥100 years) in Japan during the period from 2006 to 2016. PoD prevalence was calculated for each CoD. Trends in PoD prevalence were analyzed using the Joinpoint regression model. Changing points, annual percentage changes, and average annual percentage changes (AAPCs) were calculated to examine trends.

Results
The number of deaths more than doubled from 10 340 in 2006 to 26 427 in 2016. PoDs were composed of hospitals (52.7%), nursing homes (31.4%), own homes (13.6%) and others (2.2%). Dementia and old age increased rapidly as CoD. Proportions of hospital and home deaths decreased, with AAPCs of −2.3% (95% confidence interval [CI], −2.6 to −1.9) and −2.3% (95% CI, −3.2 to −1.4), respectively. Conversely, the proportion of deaths in nursing homes rapidly increased, with an AAPC of 6.8% (95% CI, 6.0–7.7).

Conclusions
The results revealed changes in PoD among centenarians in Japan. Understanding these transitions is indispensable for health policy in aging societies. 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=HigashionnaTsukasa en-aut-sei=Higashionna en-aut-mei=Tsukasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaruoAkinori en-aut-sei=Maruo en-aut-mei=Akinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UshioSoichiro en-aut-sei=Ushio en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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=7 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 Pharmacy, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Medicine, Icahn School of Medicine at Mount Sinai kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=aging kn-keyword=aging en-keyword=centenarians kn-keyword=centenarians en-keyword=death kn-keyword=death en-keyword=nursing home kn-keyword=nursing home en-keyword=trend kn-keyword=trend END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=8 article-no= start-page=2511 end-page=2518 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220426 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Preparation of cellulose nanocrystals coated with polymer crystals and their application in composite films en-subtitle= kn-subtitle= en-abstract= kn-abstract=Increasing the dispersibility of cellulose nanocrystals (CNCs) as a reinforcing material is highly desirable to obtain composites with enhanced mechanical properties. To this aim, nanocomposite fibers (NCF(CNC/polymer)) were fabricated by coating CNCs with polymer crystals. Poly(vinyl alcohol) (PVA) and poly(vinyl alcohol-co-ethylene) (EVOH) were crystallized from a dilute solution in the presence of CNCs, which acted as nucleating agents for polymer crystal growth on the CNC surface. NCF consisting of CNCs coated with PVA crystals (NCF(CNC/PVA)) and CNCs coated with EVOH crystals (NCF(CNC/EVOH)) were successfully obtained. Both NCF(CNC/polymer) showed good dispersibility in water, even after drying, and were used to prepare composite films with improved mechanical properties. The reinforcement effect of NCF(CNC/PVA) was greater than that of pure CNCs and NCF(CNC/EVOH). The PVA composite films exhibited optical transmittance above 99% compared with additive-free PVA films. No agglomerates appeared even under the optical microscopic observation of the PVA composite film, and NCF(CNC/PVA) dispersibility was extremely good. NCF(CNC/PVA)-added PVA composite films exhibited increased glass transition temperature compared with additive-free PVA films, and the crystallinity of the PVA film increased. The highly dispersed CNCs in the PVA matrix and the increase in the glass transition temperature and crystallinity caused an increase in the mechanical modulus of the PVA composite film at low NCF(CNC/PVA) content. Furthermore, the effect of the morphologies of cellulose nanofibers and CNCs on the mechanical properties of the composite films prepared using the respective NCFs was investigated. en-copyright= kn-copyright= en-aut-name=UchidaTetsuya en-aut-sei=Uchida en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiokaRyohei en-aut-sei=Nishioka en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YanaiRisa en-aut-sei=Yanai en-aut-mei=Risa 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=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=cellulose nanocrystals kn-keyword=cellulose nanocrystals en-keyword=composite kn-keyword=composite en-keyword=dispersibility kn-keyword=dispersibility en-keyword=mechanical properties kn-keyword=mechanical properties en-keyword=surface treatment kn-keyword=surface treatment END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=37 article-no= start-page=e202201253 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220523 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Design and Synthesis of Glycosylated Cholera Toxin B Subunit as a Tracer of Glycoprotein Trafficking in Organelles of Living Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Glycosylation of proteins is known to be essential for changing biological activity and stability of glycoproteins on the cell surfaces and in body fluids. Delivering of homogeneous glycoproteins into the endoplasmic reticulum (ER) and the Golgi apparatus would enable us to investigate the function of asparagine-linked (N-) glycans in the organelles. In this work, we designed and synthesized an intentionally glycosylated cholera toxin B-subunit (CTB) to be transported to the organelles of mammalian cells. The heptasaccharide, the intermediate structure of various complex-type N-glycans, was introduced to the CTB. The synthesized monomeric glycosyl-CTB successfully entered mammalian cells and was transported to the Golgi and the ER, suggesting the potential use of synthetic CTB to deliver and investigate the functions of homogeneous N-glycans in specific organelles of living cells. en-copyright= kn-copyright= en-aut-name=MakiYuta en-aut-sei=Maki en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawataKazuki en-aut-sei=Kawata en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LiuYanbo en-aut-sei=Liu en-aut-mei=Yanbo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GooKang‐Ying en-aut-sei=Goo en-aut-mei=Kang‐Ying kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkamotoRyo en-aut-sei=Okamoto en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KajiharaYasuhiro en-aut-sei=Kajihara en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SatohAyano en-aut-sei=Satoh en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Chemistry, Graduate School of Science, Osaka University kn-affil= affil-num=2 en-affil=Department of Chemistry, Graduate School of Science, Osaka University kn-affil= affil-num=3 en-affil=Department of Chemistry, Graduate School of Science, Osaka University kn-affil= affil-num=4 en-affil=Department of Chemistry, Graduate School of Science, Osaka University kn-affil= affil-num=5 en-affil=Department of Chemistry, Graduate School of Science, Osaka University kn-affil= affil-num=6 en-affil=Department of Chemistry, Graduate School of Science, Osaka University kn-affil= affil-num=7 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=glycoprotein kn-keyword=glycoprotein en-keyword=N-glycan kn-keyword=N-glycan en-keyword=cholera toxin kn-keyword=cholera toxin en-keyword=native chemical ligation kn-keyword=native chemical ligation en-keyword=live imaging kn-keyword=live imaging END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=37 article-no= start-page=e202201113 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220519 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Indole Editing Enabled by HFIP‐Mediated Ring‐Switch Reactions of 3‐Amino‐2‐Hydroxyindolines en-subtitle= kn-subtitle= en-abstract= kn-abstract=We found the novel reactivity of hemiaminal as a precursor for indole editing at the multi-site. The HFIP-promoted indole editing of indoline hemiaminals affords 2-arylindoles through a ring-switch sequence. The key to success of this transformation is to use a cyclic hemiaminal as an a-amino aldehyde surrogate under transient tautomeric control. This transformation features mild reaction conditions and good yields with broad functional group tolerance. The utility of this transformation is presented through the one-pot protocol and the synthesis of isocryptolepine. en-copyright= kn-copyright= en-aut-name=AbeTakumi en-aut-sei=Abe en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamashiroToshiki en-aut-sei=Yamashiro en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimizuKaho en-aut-sei=Shimizu en-aut-mei=Kaho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SawadaDaisuke en-aut-sei=Sawada en-aut-mei=Daisuke 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=hemiaminals kn-keyword=hemiaminals en-keyword=HFIP kn-keyword=HFIP en-keyword=indoles kn-keyword=indoles en-keyword=molecule editing kn-keyword=molecule editing en-keyword=ring-switch kn-keyword=ring-switch END start-ver=1.4 cd-journal=joma no-vol=289 cd-vols= no-issue=19 article-no= start-page=5971 end-page=5984 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220517 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Substrate recognition by Arg/Pro‐rich insert domain in calcium/calmodulin‐dependent protein kinase kinase for target protein kinases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Calcium/calmodulin-dependent protein kinase kinases (CaMKKs) activate CaMKI, CaMKIV, protein kinase B/Akt, and AMP-activated protein kinase (AMPK) by phosphorylating Thr residues in activation loops to mediate various Ca2+-signaling pathways. Mammalian cells expressing CaMKK alpha and CaMKK beta lacking Arg/Pro-rich insert domain (RP-domain) sequences showed impaired phosphorylation of AMPK alpha, CaMKI alpha, and CaMKIV, whereas the autophosphorylation activities of CaMKK mutants remained intact and were similar to those of wild-type CaMKKs. Liver kinase B1 (LKB1, an AMPK kinase) complexed with STRAD and MO25 and was unable to phosphorylate CaMKI alpha and CaMKIV; however, mutant LKB1 with the RP-domain sequences of CaMKK alpha and CaMKK beta inserted between kinase subdomains II and III acquired CaMKI alpha and CaMKIV phosphorylating activity in vitro and in transfected cultured cells. Furthermore, ionomycin-induced phosphorylation of hemagglutinin (HA)-CaMKI alpha at Thr177, HA-CaMKIV at Thr196, and HA-AMPK alpha at Thr172 in transfected cells was significantly suppressed by cotransfection of kinase-dead mutants of CaMKK isoforms, but these dominant-negative effects were abrogated with RP-deletion mutants, suggesting that sequestration of substrate kinases by loss-of-function CaMKK mutants requires the RP-domain. This was confirmed by pulldown experiments that showed that dominant-negative mutants of CaMKK alpha and CaMKK beta interact with target kinases but not RP-deletion mutants. Taken together, these results clearly indicate that both CaMKK isoforms require the RP-domain to recognize downstream kinases to interact with and phosphorylate Thr residues in their activation loops. Thus, the RP-domain may be a promising target for specific CaMKK inhibitors. en-copyright= kn-copyright= en-aut-name=KaneshigeRiku en-aut-sei=Kaneshige en-aut-mei=Riku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhtsukaSatomi en-aut-sei=Ohtsuka en-aut-mei=Satomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaradaYuhei en-aut-sei=Harada en-aut-mei=Yuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawamataIssei en-aut-sei=Kawamata en-aut-mei=Issei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MagariMasaki en-aut-sei=Magari en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KanayamaNaoki en-aut-sei=Kanayama en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HatanoNaoya en-aut-sei=Hatano en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SakagamiHiroyuki en-aut-sei=Sakagami en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TokumitsuHiroshi en-aut-sei=Tokumitsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Applied Chemistry and Biotechnology, Faculty of Engineering, Okayama University kn-affil= affil-num=5 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=7 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=8 en-affil=Department of Anatomy, Kitasato University School of Medicine kn-affil= affil-num=9 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=AMP-activated protein kinase kn-keyword=AMP-activated protein kinase en-keyword=Arg/Pro-rich insert domain (RP-domain) kn-keyword=Arg/Pro-rich insert domain (RP-domain) en-keyword=calcium/calmodulin-dependent protein kinase kn-keyword=calcium/calmodulin-dependent protein kinase en-keyword=calcium/calmodulin-dependent protein kinase kinase kn-keyword=calcium/calmodulin-dependent protein kinase kinase en-keyword=substrate recognition kn-keyword=substrate recognition 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=20220409 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tumor-targeted fluorescence labeling systems for cancer diagnosis and treatment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Conventional imaging techniques are available for clinical identification of tumor sites. However, detecting metastatic tumor cells that are spreading from primary tumor sites using conventional imaging techniques remains difficult. In contrast, fluorescence-based labeling systems are useful tools for detecting tumor cells at the single-cell level in cancer research. The ability to detect fluorescent-labeled tumor cells enables investigations of the biodistribution of tumor cells for the diagnosis and treatment of cancer. For example, the presence of fluorescent tumor cells in the peripheral blood of cancer patients is a predictive biomarker for early diagnosis of distant metastasis. The elimination of fluorescent tumor cells without damaging normal tissues is ideal for minimally invasive treatment of cancer. To capture fluorescent tumor cells within normal tissues, however, tumor-specific activated target molecules are needed. This review focuses on recent advances in tumor-targeted fluorescence labeling systems, in which indirect reporter labeling using tumor-specific promoters is applied to fluorescence labeling of tumor cells for the diagnosis and treatment of cancer. Telomerase promoter-dependent fluorescence labeling using replication-competent viral vectors produces fluorescent proteins that can be used to detect and eliminate telomerase-positive tumor cells. Tissue-specific promoter-dependent fluorescence labeling enables identification of specific tumor cells. Vimentin promoter-dependent fluorescence labeling is a useful tool for identifying tumor cells that undergo epithelial-mesenchymal transition (EMT). The evaluation of tumor cells undergoing EMT is important for accurately assessing metastatic potential. Thus, tumor-targeted fluorescence labeling systems represent novel platforms that enable the capture of tumor cells for the diagnosis and treatment of cancer. en-copyright= kn-copyright= en-aut-name=TazawaHiroshi en-aut-sei=Tazawa en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=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=SakuraiFuminori en-aut-sei=Sakurai en-aut-mei=Fuminori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MizuguchiHiroyuki en-aut-sei=Mizuguchi en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KobayashiHisataka en-aut-sei=Kobayashi en-aut-mei=Hisataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ImamuraTakeshi en-aut-sei=Imamura en-aut-mei=Takeshi 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= kn-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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=Laboratory of Biochemistry and Molecular Biology, Graduate School of Pharmaceutical Sciences, Osaka University kn-affil= affil-num=6 en-affil=Laboratory of Biochemistry and Molecular Biology, Graduate School of Pharmaceutical Sciences, Osaka University kn-affil= affil-num=7 en-affil=Molecular Imaging Branch, Center for Cancer Research, National Cancer Institute, National Institutes of Health kn-affil= affil-num=8 en-affil=Department of Molecular Medicine for Pathogenesis, Ehime University Graduate School of Medicine 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=adenovirus kn-keyword=adenovirus en-keyword=EMT kn-keyword=EMT en-keyword=survivin kn-keyword=survivin en-keyword=telomerase kn-keyword=telomerase en-keyword=vimentin kn-keyword=vimentin END start-ver=1.4 cd-journal=joma no-vol=128 cd-vols= no-issue= article-no= start-page=453 end-page=460 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220329 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Artificial selections for death-feigning behavior in beetles show correlated responses in amplitude of circadian rhythms, but the period of the rhythm does not en-subtitle= kn-subtitle= en-abstract= kn-abstract=One of the most important survival strategies of organisms is to avoid predators. Studying one of such strategies, namely, death-feigning behavior, has recently become more common. The success or failure of this antipredator strategy will be affected by the circadian rhythms of both prey and predator because death feigning sometimes has a diurnal rhythm. However, few studies have analyzed the effects of differences in circadian rhythms on predator-avoidance behavior at the genetic level. Recently, the relationship between genes relating to circadian rhythm and death-feigning behavior, an antipredator behavior, has been established at the molecular level. Therefore, in this study, we compared three circadian rhythm-related traits, the free-running period of rhythms, amplitude of circadian rhythms, and total activity of strains of three Tribolium species that were artificially selected for the death-feigning duration: short (S-strains) and long (L-strains) durations. As a result, the amplitude of circadian rhythms and total activity were significantly different between S- and L-strains, but there was no difference in the free-running periods of the rhythm between the strains in T. castaneum, T. confusum, and T. freemani. Although the relationship between death-feigning behavior and activity has been reported for all three species, a genetic relationship between the duration of death feigning and the amplitude of circadian rhythms has been newly found in the present study. It is important to investigate the relationship between antipredator strategies and circadian rhythms at the molecular level in the future. 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=S.

In order to improve communication QoS of NetApp clients, we propose Server Migration Service (SMS) in this paper. SMS allowsNetApp servers to migrate among different locations in the network (1) to optimally locate themselves in relation to NetApp clients and mitigate the QoS degradation caused by location-related factors (i.e., propagation delays on network links) and (2) to optimally distribute traffic load over routers and processing load over (physical) computers and decrease the energy consumption. We develop a mixed-integer programming model that determines when and to which locations NetApp servers migrate to minimize the total operating cost of SMS, i.e., the sum of the monetary penalty incurred due to QoS violation and energy cost incurred due to energy consumption, while preventing NetApp servers from excessively migrating and adversely impacting QoS of the non-SMS service that share the resource of the substrate network with SMS. Simulation results show that the model developed in this paper achieves up to 42% lower total operating cost of SMS compared to the model that only minimizes the monetary penalty of SMS without considering the energy cost of SMS. en-copyright= kn-copyright= en-aut-name=FukushimaYukinobu en-aut-sei=Fukushima en-aut-mei=Yukinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SudaTatsuya en-aut-sei=Suda en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MuraseTutomu en-aut-sei=Murase en-aut-mei=Tutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TarutaniYuya en-aut-sei=Tarutani en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YokohiraTokumi en-aut-sei=Yokohira en-aut-mei=Tokumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=The Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=University Netgroup Inc. kn-affil= affil-num=3 en-affil=Information Technology Center, Nagoya University kn-affil= affil-num=4 en-affil=The Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=The Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=IaaS kn-keyword=IaaS en-keyword=SMS (server migration service) kn-keyword=SMS (server migration service) en-keyword=server locations kn-keyword=server locations en-keyword=energy cost kn-keyword=energy cost en-keyword=monetary penaltymixed-integer programming kn-keyword=monetary penaltymixed-integer programming END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue= article-no= start-page=1876 end-page=1890 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202247 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Three highly conserved hydrophobic residues in the predicted α2‐helix of rice NLR protein Pit contribute to its localization and immune induction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nucleotide-binding leucine-rich repeat (NLR) proteins work as crucial intracellular immune receptors. N-terminal domains of NLRs fall into two groups, coiled-coil (CC) and Toll-interleukin 1 receptor domains, which play critical roles in signal transduction and disease resistance. However, the activation mechanisms of NLRs, and how their N-termini function in immune induction, remain largely unknown. Here, we revealed that the CC domain of a rice NLR Pit contributes to self-association. The Pit CC domain possesses three conserved hydrophobic residues that are known to be involved in oligomer formation in two NLRs, barley MLA10 and Arabidopsis RPM1. Interestingly, the function of these residues in Pit differs from that in MLA10 and RPM1. Although three hydrophobic residues are important for Pit-induced disease resistance against rice blast fungus, they do not participate in self-association or binding to downstream signalling molecules. By homology modelling of Pit using the Arabidopsis ZAR1 structure, we tried to clarify the role of three conserved hydrophobic residues and found that they are located in the predicted α2-helix of the Pit CC domain and involved in the plasma membrane localization. Our findings provide novel insights for understanding the mechanisms of NLR activation as well as the relationship between subcellular localization and immune induction. en-copyright= kn-copyright= en-aut-name=WangQiong en-aut-sei=Wang en-aut-mei=Qiong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LiYuying en-aut-sei=Li en-aut-mei=Yuying kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KosamiKen‐ichi en-aut-sei=Kosami en-aut-mei=Ken‐ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LiuChaochao en-aut-sei=Liu en-aut-mei=Chaochao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=LiJing en-aut-sei=Li en-aut-mei=Jing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ZhangDan en-aut-sei=Zhang en-aut-mei=Dan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MikiDaisuke en-aut-sei=Miki en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawanoYoji en-aut-sei=Kawano en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=School of Horticulture and Plant Protection Yangzhou University Yangzhou China kn-affil= affil-num=2 en-affil=CAS Center for Excellence in Molecular Plant Sciences, Shanghai Center for Plant Stress Biology Chinese Academy of Sciences Shanghai China kn-affil= affil-num=3 en-affil=CAS Center for Excellence in Molecular Plant Sciences, Shanghai Center for Plant Stress Biology Chinese Academy of Sciences Shanghai China kn-affil= affil-num=4 en-affil=School of Biotechnology Jiangsu University of Science and Technology Zhenjiang China kn-affil= affil-num=5 en-affil=CAS Center for Excellence in Molecular Plant Sciences, Shanghai Center for Plant Stress Biology Chinese Academy of Sciences Shanghai China kn-affil= affil-num=6 en-affil=School of Horticulture and Plant Protection Yangzhou University Yangzhou China kn-affil= affil-num=7 en-affil=CAS Center for Excellence in Molecular Plant Sciences, Shanghai Center for Plant Stress Biology Chinese Academy of Sciences Shanghai China kn-affil= affil-num=8 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=NLR protein kn-keyword=NLR protein en-keyword=plasma membrane localization kn-keyword=plasma membrane localization en-keyword=self-association kn-keyword=self-association en-keyword=effector triggered immunity kn-keyword=effector triggered immunity en-keyword=rice kn-keyword=rice END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=4 article-no= start-page=e05713 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220408 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relationship between patients' characteristics and efficacy of calcimimetics for primary hyperparathyroidism in the elderly en-subtitle= kn-subtitle= en-abstract= kn-abstract=Calcimimetic treatment has been reported to be effective for primary hyperparathyroidism (PHPT).

Recent studies have reported a relationship between periodontitis and obesity; however, the mechanisms of obesity’s effects on periodontitis are not well understood. On the other hand, microRNAs (miRNAs) are known to play key roles in the post-transcriptional regulation gene expression by suppressing translation and protein synthesis. We examined the association between obesity-related miRNAs and gene expression in gingival tissue using miRNA–messenger RNA (mRNA) pairing analysis in an obese rat model.

Methods
Sixteen male Wistar rats aged 8 weeks old were divided into two groups: the control group was fed a normal powdered food for 8 weeks, and the obesity group was fed a high-fat diet for 8 weeks. Distance from the cement–enamel junction to the alveolar bone crest of the first molars was measured. miRNA microarray analysis was performed on samples of serum and gingival tissue; the resulting data were used to calculate fold changes in miRNA levels in the obesity group relative to the control group, and miRNA–mRNA pairing analysis was performed to identify mRNAs potentially targeted by miRNAs of interest.

Results
Alveolar bone loss in the obesity group exceeded that in the control group (p = .017). miRNA–mRNA pairing analysis identified an association between 4 miRNAs (miR-759, miR-9a-3p, miR-203b-3p, and miR-878) that were differentially expressed in the obesity and control groups and 7 genes (Ly86, Arid5b, Rgs18, Mlana, P2ry13, Kif1b, and Myt1) expressed in gingival tissue.

Conclusion
This study revealed that several miRNAs play an important role in the mechanism of periodontal disease progression induced by the obesity. en-copyright= kn-copyright= en-aut-name=MaruyamaTakayuki en-aut-sei=Maruyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobayashiTerumasa en-aut-sei=Kobayashi en-aut-mei=Terumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugiuraYoshio en-aut-sei=Sugiura en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YonedaToshiki en-aut-sei=Yoneda en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Okayama University Academic Field of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Preventive Dentistry, Okayama University Academic Field of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Preventive Dentistry, Okayama University Academic Field of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Preventive Dentistry, Okayama University Academic Field of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Preventive Dentistry, Okayama University Academic Field of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Preventive Dentistry, Okayama University Academic Field of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=experimental animal model kn-keyword=experimental animal model en-keyword=microRNA kn-keyword=microRNA en-keyword=mRNA kn-keyword=mRNA en-keyword=obesity kn-keyword=obesity en-keyword=periodontitis kn-keyword=periodontitis END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=6 article-no= start-page=885 end-page=894 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220301 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=HopAZ1, a type III effector of Pseudomonas amygdali pv. tabaci, induces a hypersensitive response in tobacco wildfire-resistant Nicotiana tabacum 'N509' en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pseudomonas amygdali pv. tabaci (formerly Pseudomonas syringae pv. tabaci; Pta) is a gram-negative bacterium that causes bacterial wildfire disease in Nicotiana tabacum. The pathogen establishes infections by using a type III secretion system to inject type III effector proteins (T3Es) into cells, thereby interfering with the host & apos;s immune system. To counteract the effectors, plants have evolved disease-resistance genes and mechanisms to induce strong resistance on effector recognition. By screening a series of Pta T3E-deficient mutants, we have identified HopAZ1 as the T3E that induces disease resistance in N. tabacum 'N509'. Inoculation with the Pta increment hopAZ1 mutant did not induce resistance to Pta in N509. We also found that the Pta increment hopAZ1 mutant did not induce a hypersensitive response and promoted severe disease symptoms in N509. Furthermore, a C-terminal truncated HopAZ1 abolished HopAZ1-dependent cell death in N509. These results indicate that HopAZ1 is the avirulence factor that induces resistance to Pta by N509. en-copyright= kn-copyright= en-aut-name=KashiharaSachi en-aut-sei=Kashihara en-aut-mei=Sachi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimuraTakafumi en-aut-sei=Nishimura en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 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=5 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=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= 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= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=effector kn-keyword=effector en-keyword=hypersensitive responses kn-keyword=hypersensitive responses en-keyword=Pseudomonas syringae pv kn-keyword=Pseudomonas syringae pv en-keyword=tabaci kn-keyword=tabaci en-keyword=type III secretion system kn-keyword=type III secretion system END start-ver=1.4 cd-journal=joma no-vol=95 cd-vols= no-issue=9 article-no= start-page=1818 end-page=1828 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=20161230 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Downregulation of PAR-1 and PAR-2 by Rivaroxaban kn-title=Reduction of intracerebral hemorrhage by rivaroxaban after tPA thrombolysis is associated with downregulation of PAR-1 and PAR-2 en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to assess the risk of intracerebral hemorrhage (ICH) after tissue-type plasminogen activator (tPA) treatment in rivaroxaban compared with warfarin-pretreated male Wistar rat brain after ischemia in relation to activation profiles of protease-activated receptor-1, -2, -3, and -4 (PAR-1, -2, -3, and -4). After pretreatment with warfarin (0.2 mg/kg/day), low-dose rivaroxaban (60 mg/kg/day), high-dose rivaroxaban (120 mg/kg/day), or vehicle for 14 days, transient middle cerebral artery occlusion was induced for 90 min, followed by reperfusion with tPA (10 mg/kg/10 ml). Infarct volume, hemorrhagic volume, immunoglobulin G leakage, and blood parameters were examined. Twenty-four hours after reperfusion, immunohistochemistry for PARs was performed in brain sections. ICH volume was increased in the warfarin-pretreated group compared with the rivaroxaban-treated group. PAR-1, -2, -3, and -4 were widely expressed in the normal brain, and their levels were increased in the ischemic brain, especially in the peri-ischemic lesion. Warfarin pretreatment enhanced the expression of PAR-1 and PAR-2 in the peri-ischemic lesion, whereas rivaroxaban pretreatment did not. The present study shows a lower risk of brain hemorrhage in rivaroxaban-pretreated compared with warfarin-pretreated rats following tPA administration to the ischemic brain. It is suggested that the relative downregulation of PAR-1 and PAR-2 by rivaroxaban compared with warfarin pretreatment might be partly involved in the mechanism of reduced hemorrhagic complications in patients receiving rivaroxaban in clinical trials. © 2016 Wiley Periodicals, Inc. 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=YamashitaToru en-aut-sei=Yamashita en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=ShangJingwei en-aut-sei=Shang en-aut-mei=Jingwei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanoYumiko en-aut-sei=Nakano en-aut-mei=Yumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 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=8 ORCID= en-aut-name=HeitmeierStefan en-aut-sei=Heitmeier en-aut-mei=Stefan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=PerzbornElisabeth en-aut-sei=Perzborn en-aut-mei=Elisabeth kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= affil-num=1 en-affil=Departments of Neurology, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=2 en-affil=Departments of Neurology, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=3 en-affil=Departments of Neurology, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=4 en-affil=Departments of Neurology, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=5 en-affil=Departments of Neurology kn-affil= affil-num=6 en-affil=Departments of Neurology, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=7 en-affil=Departments of Neurology, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=8 en-affil=Departments of Neurology, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=9 en-affil=Bayer Pharma AG, Drug Discovery - Global Therapeutic Research Groups, Cardiovascular Pharmacology kn-affil= affil-num=10 en-affil=Bayer Pharma AG, Drug Discovery - Global Therapeutic Research Groups, Cardiovascular Pharmacology kn-affil= affil-num=11 en-affil=Departments of Neurology, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= en-keyword=PAR-3 kn-keyword=PAR-3 en-keyword=PAR-4 kn-keyword=PAR-4 en-keyword=tissue plasminogen activator kn-keyword=tissue plasminogen activator en-keyword=warfarin kn-keyword=warfarin END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue= article-no= start-page=521 end-page=525 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220211 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Isolation and identification of soil bacteria resistant to surfactants in washing detergents en-subtitle= kn-subtitle= en-abstract= kn-abstract=Linear alkylbenzene sulfonate (LAS) and polyoxyethylene lauryl ether (POLE) are the major surfactants in washing detergents. In the present study, we isolated surfactant-resistant bacteria from soil samples collected from a sports ground and a farm field. The samples were treated with 2.0% LAS or POLE at 25°C for 30 min and cultivated on agar plates at 25°C for several days, after which manifold bacterial colonies were isolated. Thereafter, we tested the ability of each bacterial isolate to resist the antibacterial activity of the surfactant. Ten LAS-resistant strains were isolated, and all were found to be Gram-negative bacteria such as Enterobacter and Pseudomonas. On the other hand, 18 POLE-resistant strains were isolated, of which 14 were Gram-positive bacteria including Bacillus and Microbacterium. Notably, one POLE-resistant strain was identified as Bacillus cereus, a potential causative agent for foodborne illness. The genera of LAS- and POLE-resistant bacteria did not overlap. Therefore, the combination of LAS and POLE could be more effective to eliminate soil bacteria from clothes and/or daily necessities. en-copyright= kn-copyright= 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=1 ORCID= en-aut-name=OkuboNaomi en-aut-sei=Okubo en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitsumoriSatoko en-aut-sei=Mitsumori en-aut-mei=Satoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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 Okayama‐City Okayama Japan kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences Okayama University Okayama‐City Okayama Japan kn-affil= en-keyword=Surfactant kn-keyword=Surfactant en-keyword=Washing detergent kn-keyword=Washing detergent en-keyword=Linear alkylbenzene sulfonate kn-keyword=Linear alkylbenzene sulfonate en-keyword=Soil bacteria kn-keyword=Soil bacteria END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue= article-no= start-page=98 end-page=101 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A case of a heterozygous ABCC6 mutation showing recurrent ischemic strokes and intracranial hemorrhages en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mutations in the ATP-binding cassette subfamily C member 6 (ABCC6) gene are responsible for pseudoxanthoma elasticum (PXE).

There are few reports of intracranial hemorrhages in patients with the ABCC6 mutation. We report the first Japanese case with a heterozygous ABCC6 mutation displaying recurrent ischemic strokes and intracranial hemorrhages.

Recently, artificial intelligence (AI) has been used in endoscopic examination and is expected to help in endoscopic diagnosis. We evaluated the feasibility of AI using convolutional neural network (CNN) systems for evaluating the depth of invasion of early gastric cancer (EGC), based on endoscopic images.

Methods
This study used a deep CNN model, ResNet152. From patients who underwent treatment for EGC at our hospital between January 2012 and December 2016, we selected 100 consecutive patients with mucosal (M) cancers and 100 consecutive patients with cancers invading the submucosa (SM cancers). A total of 3508 non-magnifying endoscopic images of EGCs, including white-light imaging, linked color imaging, blue laser imaging-bright, and indigo-carmine dye contrast imaging, were included in this study. A total of 2288 images from 132 patients served as the development dataset, and 1220 images from 68 patients served as the testing dataset. Invasion depth was evaluated for each image and lesion. The majority vote was applied to lesion-based evaluation.

Results
The sensitivity, specificity, and accuracy for diagnosing M cancer were 84.9% (95% confidence interval [CI] 82.3%–87.5%), 70.7% (95% CI 66.8%–74.6%), and 78.9% (95% CI 76.6%–81.2%), respectively, for image-based evaluation, and 85.3% (95% CI 73.4%–97.2%), 82.4% (95% CI 69.5%–95.2%), and 83.8% (95% CI 75.1%–92.6%), respectively, for lesion-based evaluation.

Conclusions
The application of AI using CNN to evaluate the depth of invasion of EGCs based on endoscopic images is feasible, and it is worth investing more effort to put this new technology into practical use.

diclofenac epolamine patches en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Topical forms of nonsteroidal anti-inflammatory drugs (NSAIDs) have been created to lessen systemic adverse effects. In general, they are believed to be well tolerated and appropriate for use as an over-the-counter (OTC) drug. Case Presentation: A 68-year-old woman visited our clinic due to tarry stool. The patient reported multiple episodes of recurrent bleeding from a gastric ulcer for 2 months and was treated with endoscopic hemostatic clipping. The patient disclosed she had been using a large number of diclofenac patches for more than 3 months. The patient was treated conservatively by discontinuation of diclofenac patches and treatment with a proton pump inhibitor and omeprazole. Conclusion: In conclusion, inappropriate use of topical NSAID patches can be a cause of peptic ulcer bleeding. Patients reporting multiple episodes of recurrent bleeding from a gastric ulcer should be questioned, particularly about the use of OTC medications that might include topical NSAID patches. en-copyright= kn-copyright= en-aut-name=OdaYuta en-aut-sei=Oda en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=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= affil-num=1 en-affil=Dentistry and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Dentistry and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Dentistry and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Dentistry and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine kn-affil= en-keyword=Gastric ulcer kn-keyword=Gastric ulcer en-keyword=topical nonsteroidal anti-inflammatory drug kn-keyword=topical nonsteroidal anti-inflammatory drug 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=20210920 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=First-line pembrolizumab vs chemotherapy in metastatic non-small-cell lung cancer: KEYNOTE-024 Japan subset en-subtitle= kn-subtitle= en-abstract= kn-abstract=This prespecified subanalysis of the global, randomized controlled phase Ill KEYNOTE-024 study of pembrolizumab vs chemotherapy in previously untreated metastatic non-small-cell lung cancer without EGFR/ALK alterations and a programmed death-ligand 1 (PD-L1) tumor proportion score of 50% or greater evaluated clinical outcomes among patients enrolled in Japan. Treatment consisted of pembrolizumab 200 mg every 3 weeks (35 cycles) or platinum-based chemotherapy (four to six cycles). The primary end-point was progression-free survival; secondary end-points included overall survival and safety. Of 305 patients randomized in KEYNOTE-024 overall, 40 patients were enrolled in Japan (all received treatment: pembrolizumab, n = 21; chemotherapy, n = 19). The hazard ratio (HR) for progression-free survival by independent central review (data cut-off date, 10 July 2017) was 0.25 (95% confidence interval [CI], 0.10-0.64; one-sided, nominal P = .001). The HR for overall survival (data cut-off date, 15 February 2019) was 0.39 (95% CI, 0.17-0.91; one-sided, nominal P = .012). Treatment-related adverse events occurred in 21/21 (100%) pembrolizumab-treated and 18/19 (95%) chemotherapy-treated patients; eight patients (38%) and nine patients (47%), respectively, had grade 3-5 events. Immune-mediated adverse events and infusion reactions occurred in 11 patients (52%) and four patients (21%), respectively; four patients (19%) and one patient (5%), respectively, had grade 3-5 events. Consistent with results from KEYNOTE-024 overall, first-line pembrolizumab improved progression-free survival and overall survival vs chemotherapy with manageable safety among Japanese patients with metastatic non-small-cell lung cancer without EGFRIALK alterations and a PD-L1 tumor proportion score of 50% or greater. en-copyright= kn-copyright= en-aut-name=SatouchiMiyako en-aut-sei=Satouchi

This study assessed thyX essentiality in Mycobacterium bovis BCG strains using CRISPR interference based gene silencing and found that thyX is not essential in an M. bovis BCG Tokyo derivative strain. A thyX deletion mutant strain was successfully constructed from that strain, which reinforces the non-essentiality of thyX under a certain genetic background. en-copyright= kn-copyright=

conductivities en-subtitle= kn-subtitle= en-abstract= kn-abstract=Highly porous rigid polybenzoxazole (PBO) network films were prepared using a precursor-mediated fabrication method. The obtained PBO network films possessed high porosities of similar to 40%, as calculated from their apparent densities. In addition, the 5%-weight-loss temperatures of the films were >= 570 degrees C under nitrogen atmosphere, demonstrating an excellent thermal stability. The electrical conductivities of the obtained PBO network films and phosphoric-acid-doped PBO network films were also evaluated. In addition, PBO network films containing pyridine rings were prepared and subjected to phosphoric acid doping. The resultant films were found to exhibit the highest conductivities of the films considered in this study owing to proton conduction both between phosphate groups and between the pyridine rings. The highest conductivity was found for a film prepared from a phosphoric-acid-doped PBO network containing pyridine rings, that is, 2.09 x 10(-1) S/cm at 150 degrees C, which was higher than that of Nafion (TM). Therefore, these films can be used at higher temperatures than that of Nafion (TM). en-copyright= kn-copyright= en-aut-name=UchidaTetsuya en-aut-sei=Uchida en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OnishiYukihisa en-aut-sei=Onishi en-aut-mei=Yukihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GotoAtsu en-aut-sei=Goto en-aut-mei=Atsu 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=Graduate School of Natural Science and Technology Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology Okayama University kn-affil= en-keyword=rigid polymer network kn-keyword=rigid polymer network en-keyword=heat resistance kn-keyword=heat resistance en-keyword=proton kn-keyword=proton en-keyword=phosphoric acid kn-keyword=phosphoric acid en-keyword=conductivity kn-keyword=conductivity END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=9 article-no= start-page=e04574 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210907 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Longitudinal observation of insulin secretory ability before and after the onset of immune checkpoint inhibitor-induced diabetes mellitus: A report of two cases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immune checkpoint inhibitor-induced diabetes mellitus is a rare immune-related adverse event.

Gonadal dysfunction occurs at an early stage after this treatment, and such patients may require hormone replacement therapy. Genital chronic graft-versus-host disease is a lesser-known complication of HSCT that begins with vulvar discomfort and dysuria and progresses to sexual dysfunction and retention of menstrual blood due to vaginal stenosis and obstruction; thus, significantly impairing the patient's quality of life. We describe three women who underwent vaginal reconstruction because of genital chronic graft-versus-host disease. We discuss the surgical techniques, including double cross plasty that were performed in each case. Surgical interventions enabled the continuation of HRT and facilitated sexual intercourse. In conclusion, gynecologists should be aware that genital chronic graft-versus-host disease can occur after HSCT, and that surgical treatment options are available to improve patients' symptoms and quality of life. en-copyright= kn-copyright= en-aut-name=KamadaYasuhiko en-aut-sei=Kamada en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KusumotoRie en-aut-sei=Kusumoto en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KashinoChiaki en-aut-sei=Kashino en-aut-mei=Chiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KuboKotaro en-aut-sei=Kubo en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MitsuiTakashi en-aut-sei=Mitsui en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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= affil-num=4 en-affil=Department of Obstetrics and Gynecology Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Obstetrics and Gynecology Okayama University Hospital kn-affil= en-keyword=double cross plasty kn-keyword=double cross plasty en-keyword=genital chronic graft-versus-host disease kn-keyword=genital chronic graft-versus-host disease en-keyword=hematocolpos kn-keyword=hematocolpos en-keyword=hematopoietic stem cell transplantation kn-keyword=hematopoietic stem cell transplantation en-keyword=vaginal reconstruction kn-keyword=vaginal reconstruction END start-ver=1.4 cd-journal=joma no-vol=2021 cd-vols= no-issue= article-no= start-page=1 end-page=11 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021929 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Investigation of the molecular causes underlying physical abnormalities in Diamond‐Blackfan anemia patients with RPL5 haploinsufficiency en-subtitle= kn-subtitle= en-abstract= kn-abstract=Diamond-Blackfan anemia (DBA) is a genetic disorder caused by mutations in genes encoding ribosomal proteins and characterized by erythroid aplasia and various physical abnormalities. Although accumulating evidence suggests that defective ribosome biogenesis leads to p53-mediated apoptosis in erythroid progenitor cells, little is known regarding the underlying causes of the physical abnormalities. In this study, we established induced pluripotent stem cells from a DBA patient with RPL5 haploinsufficiency. These cells retained the ability to differentiate into osteoblasts and chondrocytes. However, RPL5 haploinsufficiency impaired the production of mucins and increased apoptosis in differentiated chondrocytes. Increased expression of the pro-apoptotic genes BAX and CASP9 further indicated that RPL5 haploinsufficiency triggered p53-mediated apoptosis in chondrocytes. MDM2, the primary negative regulator of p53, plays a crucial role in erythroid aplasia in DBA patient. We found the phosphorylation level of MDM2 was significantly decreased in RPL5 haploinsufficient chondrocytes. In stark contrast, we found no evidence that RPL5 haploinsufficiency impaired osteogenesis. Collectively, our data support a model in which RPL5 haploinsufficiency specifically induces p53-mediated apoptosis in chondrocytes through MDM2 inhibition, which leads to physical abnormalities in DBA patients. en-copyright= kn-copyright= en-aut-name=FukuiYuko en-aut-sei=Fukui en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayanoSatoru en-aut-sei=Hayano en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawanabeNoriaki en-aut-sei=Kawanabe en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangZiyi en-aut-sei=Wang en-aut-mei=Ziyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShimadaAkira en-aut-sei=Shimada en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SaitoMegumu K. en-aut-sei=Saito en-aut-mei=Megumu K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AsakaIsao en-aut-sei=Asaka en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences Okayama University kn-affil= affil-num=2 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences Okayama University kn-affil= affil-num=3 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences Okayama University kn-affil= affil-num=4 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences Okayama University kn-affil= affil-num=5 en-affil=Department of Pediatric Hematology/Oncology Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Clinical Application, Center for iPS Cell Research and Application Kyoto University kn-affil= affil-num=7 en-affil=Department of Fundamental Cell Technology, Center for iPS Cell Research and Application Kyoto University kn-affil= affil-num=8 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences Okayama University kn-affil= en-keyword=iPS cell kn-keyword=iPS cell en-keyword=RPL5 kn-keyword=RPL5 en-keyword=cleft lip and palate kn-keyword=cleft lip and palate en-keyword=chondrocyte kn-keyword=chondrocyte en-keyword=Diamond-Blackfan Anemia kn-keyword=Diamond-Blackfan Anemia END start-ver=1.4 cd-journal=joma no-vol=109 cd-vols= no-issue=11 article-no= start-page=3916 end-page=3928 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021916 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The eco‐evolutionary dynamics of prior selfing rates promote coexistence without niche partitioning under conditions of reproductive interference en-subtitle= kn-subtitle= en-abstract= kn-abstract=1. Pollinator-mediated reproductive interference can occur when two or more plant species share the same pollinators. Recent studies have suggested that prior autonomous selfing mitigates reproductive interference, potentially facilitating coexistence even in the absence of pollination niche partitioning (i.e. the pre-emptive selfing hypothesis). However, whether the evolution of prior selfing promotes coexistence, in the context of the eco-evolutionary dynamics of population size, selfing rates and inbreeding depression, remains poorly understood.
2. We constructed an individual-based model to examine the conditions under which the evolution of prior selfing promotes coexistence in the context of mutual reproductive interference. In the model, two plant species compete by way of mutual reproductive interference, and both have the potential to evolve the capacity for prior autonomous selfing. We expected that purging of deleterious mutations might result in evolutionary rescue, assuming that the strength of inbreeding depression declines as the population selfing rate increases; this would enable inferior competitors to maintain population density through the evolution of prior selfing.
3. Our simulation demonstrated that evolution of prior selfing may promote coexistence, whereas reproductive interference in the absence of such evolution results in competitive exclusion. We found that lower pollinator availability is likely to favour rapid evolutionary shifts to higher prior selfing rates, thereby neutralising the negative effects of reproductive interference in both species. When the strength of inbreeding depression decreased with an increase in the population-level selfing rate, moderate pollinator availability resulted in long-term coexistence in which relative abundance-dependent selection on the prior selfing rate served to intermittently maintain the population density of the inferior competitor.
4. Synthesis. We demonstrate that the evolution of prior selfing may increase population growth rates of inferior competitors and may consequently promote long-term coexistence via an evolutionary rescue. This constitutes a novel mechanism explaining the co-evolutionary coexistence of closely related plant species without niche partitioning, and is consistent with recent studies reporting that closely related species with mixed mating systems can co-occur sympatrically, even under conditions of mutual reproductive interference. en-copyright= kn-copyright= en-aut-name=KatsuharaKoki en-aut-sei=Katsuhara en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TachikiYuuya en-aut-sei=Tachiki en-aut-mei=Yuuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IritaniRyosuke en-aut-sei=Iritani en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UshimaruAtushi en-aut-sei=Ushimaru en-aut-mei=Atushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Human Development and Environment, Kobe University Kobe kn-affil= affil-num=2 en-affil=Department of Biological Sciences Tokyo Metropolitan University Tokyo Japan kn-affil= affil-num=3 en-affil=Interdisciplinary Theoretical and Mathematical Sciences Program (iTHEMS) RIKEN Wako Saitama Japan kn-affil= affil-num=4 en-affil=Graduate School of Human Development and Environment Kobe University Kobe Japan kn-affil= en-keyword=Co-evolution kn-keyword=Co-evolution en-keyword=evolutionary rescue kn-keyword=evolutionary rescue en-keyword=inbreeding depression kn-keyword=inbreeding depression en-keyword=individual-based model kn-keyword=individual-based model en-keyword=mixed mating kn-keyword=mixed mating en-keyword=pollinator-mediated competition kn-keyword=pollinator-mediated competition en-keyword=reproductive ecology kn-keyword=reproductive ecology en-keyword=selfing syndrome kn-keyword=selfing syndrome END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=1 end-page=13 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021916 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of lymph node dissection on clinical outcomes of intrahepatic cholangiocarcinoma: Inverse probability of treatment weighting with survival analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Lymph node metastasis (LNM) has been established as a critical risk factor for prognosis in intrahepatic cholangiocarcinoma (ICC). The clinical implications of lymph node dissection (LND) have been debated. This study aimed to clarify the prognostic impact of LND by multicenter retrospective analysis.

Methods: A total of 310 ICC patients who had undergone curative resection between 2000 and 2016 were retrospectively analyzed. The prognostic impact of LND was estimated under an inverse probability of treatment weighting (IPTW) approach using propensity scores.

Results: LND was performed for 224 patients (72%), with LNM pathologically confirmed in 90 patients (40%). Prognosis was poorer for patients with LNM (median survival, 16.9 months) than for those without (57.2 months; P < .0001). One-, 3-, and 5-year overall survival rates (OS) were comparable among LND+ (81.6%, 48.0%, and 37.5%, respectively) and LND- groups (81.6%, 55.4%, and 44.6%, respectively). However, advanced tumor, as characterized by larger tumor, multinodular lesions, and serosal invasion, was significantly more frequent in the LND+ group than in the LND- group. After IPTW adjusting for imbalances, 1-, 3-, and 5-year OS were better in the LND+ group (83.5%, 52.2%, and 42.8%, respectively) than in the LND- group (71.9%, 32.4%, and 23.4%, respectively; P = .046). LND thus showed significant prognostic impact (hazard ratio = 0.58, 95%CI = |0.39|-|0.84|, P = .005), especially in hilar ICC. However, peripheral ICC displayed no therapeutic benefit from LND.

Conclusions: LND could have a significant role to play in improving oncologic outcomes. Therapeutic LND should be implemented on the basis of tumor location and tumor advancement. en-copyright= kn-copyright= en-aut-name=UmedaYuzo en-aut-sei=Umeda en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=SatohDaisuke en-aut-sei=Satoh en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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=7 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=8 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=9 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=10 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=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Surgery, Okayama Saiseikai General Hospital kn-affil= affil-num=4 en-affil=Department of Surgery, Hiroshima Citizens Hospital kn-affil= affil-num=5 en-affil=Department of Surgery, Kochi Health Sciences Center kn-affil= affil-num=6 en-affil=Department of Surgery, Himeji Red Cross Hospital kn-affil= affil-num=7 en-affil=Department of Surgery, National Hospital Organization Fukuyama Medical Center kn-affil= affil-num=8 en-affil=Department of Surgery, Tottori Municipal Hospital 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= en-keyword=intrahepatic cholangiocarcinoma kn-keyword=intrahepatic cholangiocarcinoma en-keyword=lymph node excision kn-keyword=lymph node excision en-keyword=multicenter study kn-keyword=multicenter study en-keyword=propensity score kn-keyword=propensity score en-keyword=retrospective studies kn-keyword=retrospective studies END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=1 end-page=10 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210829 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Regulation of germination by targeted mutagenesis of grain dormancy genes in barley en-subtitle= kn-subtitle= en-abstract= kn-abstract=High humidity during harvest season often causes pre-harvest sprouting in barley (Hordeum vulgare). Prolonged grain dormancy prevents pre-harvest sprouting; however, extended dormancy can interfere with malt production and uniform germination upon sowing. In this study, we used Cas9-induced targeted mutagenesis to create single and double mutants in QTL FOR SEED DORMANCY 1 (Qsd1) and Qsd2 in the same genetic background. We performed germination assays in independent qsd1 and qsd2 single mutants, as well as in two double mutants, which revealed a strong repression of germination in the mutants. These results demonstrated that normal early grain germination requires both Qsd1 and Qsd2 function. However, germination of qsd1 was promoted by treatment with 3% hydrogen peroxide, supporting the notion that the mutants exhibit delayed germination. Likewise, exposure to cold temperatures largely alleviated the block of germination in the single and double mutants. Notably, qsd1 mutants partially suppress the long dormancy phenotype of qsd2, while qsd2 mutant grains failed to germinate in the light, but not in the dark. Consistent with the delay in germination, abscisic acid accumulated in all mutants relative to the wild type, but abscisic acid levels cannot maintain long-term dormancy and only delay germination. Elucidation of mutant allele interactions, such as those shown in this study, are important for fine-tuning traits that will lead to the design of grain dormancy through combinations of mutant alleles. Thus, these mutants will provide the necessary germplasm to study grain dormancy and germination in barley. en-copyright= kn-copyright= en-aut-name=HisanoHiroshi en-aut-sei=Hisano en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HoffieRobert E. en-aut-sei=Hoffie en-aut-mei=Robert E. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AbeFumitaka en-aut-sei=Abe en-aut-mei=Fumitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MunemoriHiromi en-aut-sei=Munemori en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsuuraTakakazu en-aut-sei=Matsuura en-aut-mei=Takakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=EndoMasaki en-aut-sei=Endo en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MikamiMasafumi en-aut-sei=Mikami en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakamuraShingo en-aut-sei=Nakamura en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KumlehnJochen en-aut-sei=Kumlehn en-aut-mei=Jochen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SatoKazuhiro en-aut-sei=Sato en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) Gatersleben kn-affil= affil-num=3 en-affil=Institute of Crop Science, NARO kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Institute of Agrobiological Sciences, NARO kn-affil= affil-num=7 en-affil=Institute of Agrobiological Sciences, NARO kn-affil= affil-num=8 en-affil=Institute of Crop Science, NARO kn-affil= affil-num=9 en-affil=Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) Gatersleben kn-affil= affil-num=10 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Hordeum vulgare kn-keyword=Hordeum vulgare en-keyword=seed dormancy kn-keyword=seed dormancy en-keyword=targeted genome modification kn-keyword=targeted genome modification en-keyword=CRISPR kn-keyword=CRISPR en-keyword=Cas9 nuclease kn-keyword=Cas9 nuclease en-keyword=pre-harvest sprouting kn-keyword=pre-harvest sprouting END start-ver=1.4 cd-journal=joma no-vol=188A cd-vols= no-issue= article-no= start-page=249 end-page=252 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021828 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A novel pathogenic variant p.Asp797Val in IFIH1 in a Japanese boy with overlapping Singleton-Merten syndrome and Aicardi-Goutieres syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pathogenic-activating variants of interferon induced with Helicase C domain 1 (IFIH1) cause Singleton-Merten (S-M) syndrome, which accompanies acro-osteolysis, loss of permanent teeth, and aortic calcification, as well as causing Aicardi-Goutières (A-G) syndrome, which shows progressive encephalopathy, spastic paraplegia, and calcification of basal ganglia.

This study aimed to determine whether the cardio-ankle vascular index (CAVI), based on the blood pressure-independent stiffness parameter beta and reflecting arterial stiffness from the origin of the ascending aorta, is a good predictor of cardiovascular events in patients with cardiovascular disease risk factors in a large prospective cohort.

METHODS AND RESULTS: This multicenter prospective cohort study, commencing in May 2013, with a 5-year follow-up period, included patients (aged 40-74 years) with cardiovascular disease risks. The primary outcome was the composite of cardiovascular death, nonfatal stroke, or nonfatal myocardial infarction. Among 2932 included patients, 2001 (68.3%) were men; the mean (SD) age at diagnosis was 63 (8) years. During the median follow-up of 4.9 years, 82 participants experienced primary outcomes. The CAVI predicted the primary outcome (hazard ratio, 1.38; 95% CI, 1.16-1.65; P<0.001). In terms of event subtypes, the CAVI was associated with cardiovascular death and stroke but not with myocardial infarction. When the CAVI was incorporated into a model with known cardiovascular disease risks for predicting cardiovascular events, the global chi(2) value increased from 33.8 to 45.2 (P<0.001), and the net reclassification index was 0.254 (P=0.024).

CONCLUSIONS: This large cohort study demonstrated that the CAVI predicted cardiovascular events. en-copyright= kn-copyright= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name=

To date, not much is known about patient disposition after RRS activation, especially discharge home. This study aimed to investigate the prevalence, characteristics, and outcomes of patients with adverse events who required RRS activation.
Methods: Retrospective data from the In-Hospital Emergency Registry in Japan collected from April 2016 to November 2020 were eligible for our analysis. We divided patients into Home Discharge, Transfer, and Death groups. The primary outcome was the prevalence of direct discharge home, and independently associated factors were determined using multivariable logistic regression.
Results: We enrolled 2,043 patients who met the inclusion criteria. The prevalence of discharge home was 45.7%; 934 patients were included in the Home Discharge group. Age (adjusted odds ratio [AOR] 0.96; 95% confidence interval [CI], 0.95-0.97), malignancy (AOR 0.69; 95% CI, 0.48-0.99), oxygen administration before RRS (AOR 0.49; 95% CI, 0.36-0.66), cerebral performance category score on admission (AOR 0.38; 95% CI, 0.26-0.56), do not attempt resuscitation order before RRS (AOR 0.17; 95% CI, 0.10-0.29), RRS call for respiratory failure (AOR 0.50; 95% CI, 0.34-0.72), RRS call for stroke (AOR 0.12; 95% CI, 0.03-0.37), and intubation (AOR 0.20; 95% CI, 0.12-0.34) were independently negative, and RRS call for anaphylaxis (AOR 15.3; 95% CI, 2.72-86.3) was positively associated with discharge home.
Conclusion: Less than half of the in-hospital patients under RRS activation could discharge home. Patients' conditions before RRS activation, disorders requiring RRS activation, and intubation were factors that affected direct discharge home. en-copyright= kn-copyright= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=FujiwaraToshifumi en-aut-sei=Fujiwara en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NaitoTakaki en-aut-sei=Naito en-aut-mei=Takaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HommaYosuke en-aut-sei=Homma en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujimotoYoshihisa en-aut-sei=Fujimoto en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakayaMorooka en-aut-sei=Takaya en-aut-mei=Morooka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamamoriYuji en-aut-sei=Yamamori en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakadaTaka-Aki en-aut-sei=Nakada en-aut-mei=Taka-Aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=11 ORCID= en-aut-name=FujitaniShigeki en-aut-sei=Fujitani en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=In-Hospital Emergency Study Group en-aut-sei=In-Hospital Emergency Study Group en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=Emergency Department, Okayama Saiseikai General Hospital kn-affil= affil-num=4 en-affil=Department of Emergency and Critical Care Medicine, St. Marianna University School of Medicine kn-affil= affil-num=5 en-affil=Department of Emergency and Critical Care Medicine, Tokyo Bay Urayasu Ichikawa Medical Center kn-affil= affil-num=6 en-affil=Department of Emergency and Critical Care Medicine, Tokyo Bay Urayasu Ichikawa Medical Center kn-affil= affil-num=7 en-affil=Emergency and Critical Care Medical Center, Osaka City General Hospital kn-affil= affil-num=8 en-affil=Department of Emergency and Critical Care Medicine, Shimane Prefectural Central Hospital kn-affil= affil-num=9 en-affil=Department of Emergency and Critical Care Medicine, Chiba University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Emergency and Critical Care Medicine, St. Marianna University School of Medicine kn-affil= affil-num=13 en-affil= kn-affil= en-keyword=discharge to home kn-keyword=discharge to home en-keyword=DNAR kn-keyword=DNAR en-keyword=RRS kn-keyword=RRS en-keyword=serious adverse event kn-keyword=serious adverse event END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=1 article-no= start-page=e143 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191124 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of a point-of-care serum creatinine measurement device and the impact on diagnosis of acute kidney injury in pediatric cardiac patients: A retrospective, single center study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and aims: Agreement between measurements of creatinine concentrations using point-of-care (POC) devices and measurements conducted in a standard central laboratory is unclear for pediatric patients. Our objectives were (a) to assess the agreement for pediatric patients and (b) to compare the incidence of postoperative acute kidney injury (AKI) according to the two methods.
Methods: This retrospective, single-center study included patients under 18 years of age who underwent cardiac surgery and who were admitted into the pediatric intensive care unit of a tertiary teaching hospital (Okayama University Hospital, Japan) from 2013 to 2017. The primary objective was to assess the correlation and the agreement between measurements of creatinine concentrations by a Radiometer blood gas analyzer (Cre(gas)) and those conducted in a central laboratory (Cre(lab)). The secondary objective was to compare the incidence of postoperative AKI between the two methods based on Kidney Disease Improving Global Outcomes (KDIGO) criteria.
Results: We analyzed the results of 1404 paired creatinine measurements from 498 patients, whose median age was 14 months old (interquartile range [IQR] 3, 49). The Pearson correlation coefficient of Cre(gas) vs Cre(lab) was 0.968 (95% confidence interval [CI], 0.965-0.972, P < 0.001). The median bias between Cre(gas) and Cre(lab) was 0.02 (IQR -0.02, 0.05) mg/dL. While 199 patients (40.0%) were diagnosed as having postoperative AKI based on Cre(lab), 357 patients (71.7%) were diagnosed as having postoperative AKI based on Cre(gas) (Kappa = 0.39, 95% CI, 0.33-0.46). In a subgroup analysis of patients whose Cre(gas) and Cre(lab) were measured within 1 hour, similar percentage of patients were diagnosed as having postoperative AKI based on Cre(gas) and Cre(lab) (42.8% vs 46.0%; Kappa = 0.76, 95% CI, 0.68-0.84).
Conclusion: There was an excellent correlation between Cre(gas) and Cre(lab) in pediatric patients. Although more patients were diagnosed as having postoperative AKI based on Cre(gas) than based on Cre(lab), paired measurements with a short time gap showed good agreement on AKI diagnosis. en-copyright= kn-copyright= en-aut-name=KimuraSatoshi en-aut-sei=Kimura en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwasakiTatsuo en-aut-sei=Iwasaki en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimizuKazuyoshi en-aut-sei=Shimizu en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KanazawaTomoyuki en-aut-sei=Kanazawa en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawaseHirokazu en-aut-sei=Kawase en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShiojiNaohiro en-aut-sei=Shioji en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KuroeYasutoshi en-aut-sei=Kuroe en-aut-mei=Yasutoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IsoyamaSatoshi en-aut-sei=Isoyama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Resuscitation, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Resuscitation, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Anesthesiology and Resuscitation, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Anesthesiology and Resuscitation, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Anesthesiology and Resuscitation, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Anesthesiology and Resuscitation, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Anesthesiology and Resuscitation, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Anesthesiology and Resuscitation, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Anesthesiology and Resuscitation, Okayama University Hospital kn-affil= en-keyword=acute kidney injury kn-keyword=acute kidney injury en-keyword=cardiac surgical procedures kn-keyword=cardiac surgical procedures en-keyword=children kn-keyword=children en-keyword=creatinine kn-keyword=creatinine en-keyword=point-of-care kn-keyword=point-of-care END start-ver=1.4 cd-journal=joma no-vol=169 cd-vols= no-issue= article-no= start-page=959 end-page=965 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202175 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Selection for age at reproduction changes pre‐mating period and mating frequency in Zeugodacus cucurbitae : impacts on insect quality control en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the mass-rearing of insects for sterile insect technique (SIT), it is important to maintain the quality of mass-reared males so that they can compete with wild males in mating with wild females. Mass-reared insects sometimes have shorter pre-mating periods and higher mating frequencies than their wild conspecifics. Indeed, this was the case for mass-reared individuals of the melon fly, Zeugodacus cucurbitae (Coquillett) (Diptera: Tephritidae), used in the SIT program to eradicate the melon fly on the Southwest Islands of Japan. Therefore, I hypothesized that divergent artificial selection for age at reproduction altered these traits in the melon fly as well. To examine the effects of eggs produced by younger parents on each generation, six artificially selected lines were established, for which eggs were collected from young (Y lines) and old (O lines) females. Then, the pre-mating periods and mating frequencies in males and females of the selected lines were compared. The results show a decreased pre-mating period and an increased mating frequency in younger lines compared to older lines, which was driven by males rather than females. These traits ensure efficient offspring production in mass-rearing, and are likely advantageous to the success of SIT programs. The impact of artificially selecting for these traits, especially in males, on insect quality and the efficiency of SIT is discussed. 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= affil-num=1 en-affil=Laboratory of Evolutionary Ecology, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Zeugodacus cucurbitae kn-keyword=Zeugodacus cucurbitae en-keyword=mass-rearing kn-keyword=mass-rearing en-keyword=mating kn-keyword=mating en-keyword=melon fly kn-keyword=melon fly en-keyword=quality 16 control kn-keyword=quality 16 control en-keyword=sterile insect technique kn-keyword=sterile insect technique en-keyword=SIT kn-keyword=SIT en-keyword=Diptera kn-keyword=Diptera en-keyword=Tephritidae kn-keyword=Tephritidae en-keyword=correlated responses kn-keyword=correlated responses END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=7 article-no= start-page=e04583 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210723 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Barium appendicitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=We have presented a case of barium appendicitis, which is a rare complication of barium enema studies.

Methods: MDs were defined according to Japanese guideline criteria: (a) age >70-years, (b) blood pressure <= 130/80 mmHg on hypertension medicine, (c) body mass index >25 to <= 32 kg/m(2), (d) 24-h creatinine clearance >= 70 to <80 ml/min/1.73 m(2), and (e) hemoglobin A1c > 6.2 or <= 6.5 with oral diabetic medicine. Fifty-three of 114 donors were MDs. We compared donor kidney functions until 60 months postoperatively.
Results: No kidney function parameters were different between SDs and MDs. When comparing SD and MD + DM, MD + DM had a lower postoperative eGFR (48 vs. 41 (1 (month), p = .02), 49 vs. 40 (12, p < .01), 48 vs. 42 (24, p = .04), 47 vs. 38 (36, p = .01)) and the percentage of residual eGFR (SD vs. MD + DM: 63 vs. 57 (1 (month), p < .01), 63 vs. 57 (2, p < .01), 64 vs. 56 (12, p < .01), 63 vs. 57 (24, p < .01), 63 vs. 52 (36, p = .02)). However, when MD with a single risk factor of DM was compared to SD, the difference disappeared. Nine out of 12 (75%) MD + DM had >= 2 risk factors.
Conclusions: Although long-term observation of donor kidney function is necessary, careful MD + DM selection had the potential to expand the donor pool. en-copyright= kn-copyright=

Abdominal computed tomography confirmed the gastric contents, detecting multiple stick-like and rod-shaped high-density structures. Gastric lavage was performed to minimize absorption of the potentially lethal nicotine dose. The patient exhibited only mild gastrointestinal symptoms. Emergency physicians should be aware of this novel heat-not-burn cigarette and its toxicity. en-copyright= kn-copyright= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamaguchiHisashi en-aut-sei=Hamaguchi en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaeSouichiro en-aut-sei=Mae en-aut-mei=Souichiro 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= 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 Medicine, Kasaoka Daiichi Hospital kn-affil= affil-num=3 en-affil=Department of Emergency Medicine, Kasaoka Daiichi Hospital 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= en-keyword=cigarette kn-keyword=cigarette en-keyword=computed tomography kn-keyword=computed tomography en-keyword=gastric lavage kn-keyword=gastric lavage en-keyword=nicotine kn-keyword=nicotine en-keyword=suicide attempt kn-keyword=suicide attempt en-keyword=tobacco kn-keyword=tobacco en-keyword=toxicity kn-keyword=toxicity END start-ver=1.4 cd-journal=joma no-vol=1 cd-vols= no-issue=5 article-no= start-page=1097 end-page=1100 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200525 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Glycogenic hepatopathy following attempted suicide by long-acting insulin overdose in patient with type 1 diabetes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Patients with poorly controlled insulin-dependent type 1 or type 2 diabetes rarely present with glycogenic hepatopathy, which is characterized by hepatomegaly and liver enzyme abnormalities. Glycogenic hepatopathy occurs as a consequence of excessive accumulation of glycogen in hepatocytes caused by insulin. We report a young male patient with type 1 diabetes mellitus who developed glycogenic hepatopathy following a suicide attempt by insulin overdose via subcutaneous injection. The patient's medication/nutrition compliance and adherence to insulin were poorly controlled due to comorbid schizophrenia. Our patient required a large amount of continuous glucose to maintain euglycemia for persistent intractable hypoglycemia induced by overdose of long-acting insulin. On admission day 4, the patient presented elevated transaminases, hepatomegaly, and lactic acidosis. Computed tomography revealed swollen liver parenchyma with a diffusely high absorption. The patient gradually recovered without any medical intervention except for adequate control of blood sugar and was moved to a psychiatric ward on day 8 for schizophrenia management. This report may help emergency physicians be aware of the common symptoms, clinical course, and pathophysiology of glycogenic hepatopathy. Doctors should include glycogenic hepatopathy in the differential diagnosis of abnormal liver enzymes and hepatomegaly for those with poorly controlled insulin-dependent diabetes mellitus or unstable blood sugar levels due to insulin overdose like our patient. en-copyright= kn-copyright= en-aut-name=FujisakiNoritomo en-aut-sei=Fujisaki en-aut-mei=Noritomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KosakiYoshinori en-aut-sei=Kosaki en-aut-mei=Yoshinori 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=HigakiTaiki en-aut-sei=Higaki en-aut-mei=Taiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamadaTaihei en-aut-sei=Yamada en-aut-mei=Taihei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KogaHitoshi en-aut-sei=Koga en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=GochiAkira en-aut-sei=Gochi en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care and Disaster Medicine,Okayama University kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care and Disaster Medicine,Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care and Disaster Medicine,Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care and Disaster Medicine,Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care and Disaster Medicine,Okayama University kn-affil= affil-num=6 en-affil=Department of Emergency Medicine, StMaria Hospital kn-affil= affil-num=7 en-affil=Department of Surgery, Ibara City Hospital kn-affil= affil-num=8 en-affil=Department of Emergency, Critical Care and Disaster Medicine,Okayama University kn-affil= affil-num=9 en-affil=Department of Emergency, Critical Care and Disaster Medicine,Okayama University kn-affil= en-keyword=diabetes mellitus kn-keyword=diabetes mellitus en-keyword=drug overdose kn-keyword=drug overdose en-keyword=glycogen kn-keyword=glycogen en-keyword=hypoglycemia kn-keyword=hypoglycemia en-keyword=insulin kn-keyword=insulin en-keyword=liver disorder kn-keyword=liver disorder en-keyword=schizophrenia kn-keyword=schizophrenia END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=1 article-no= start-page=181 end-page=186 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=20080101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Appearance of Multidrug-Resistant Opportunistic Bacteria on the Gingiva During Leukemia Treatment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Dentists generally recognize the importance of periodontal treatment inpatients with leukemia, with the most attention paid to preventing the development of odontogenic infection. For physicians, the worst type of infection is one caused by multidrug-resistant bacteria. Here, we report a patient with an abnormal increase in multidrug-resistant opportunistic bacteria in the gingiva during hematopoietic cell transplantation (HCT).

Methods: A 53-year-old woman receiving HCT for leukemia had an insufficient blood cell count for invasive periodontal treatment before HCT. Even brushing caused difficulties with hemostasis. Therefore, frequent pocket irrigation and local minocycline administration were performed.

Results: The multidrug-resistant opportunistic bacterium Stenotrophomonas maltophilia was detected first in phlegm 2 days before HCT, and it was detected in a gingival smear and a blood sample 7 and I I days after HCT, respectively. The patient developed sepsis on day I I and died 14 days after HCT. Frequent irrigation and local antibiotic application were ineffective against S. maltophilia on the gingiva. Inflammatory gingiva without scaling and root planing showed bleeding tendency, and this interfered with the eradication of this bacterium.

Conclusions: The gingiva in patients undergoing leukemia treatment acts as sites of proliferation and reservoirs for multidrug-resistant opportunistic bacteria. Severe systemic infection by multidrug-resistant bacteria in such patients with leukemia also may involve the gingiva. To prevent abnormal increases in such bacteria on the gingiva, scaling and/or root planing before chemotherapy, which reduces bleeding on brushing during the neutropenic period caused by chemotherapy, may contribute to infection control in such patients, although it was impossible in this case. en-copyright= kn-copyright= en-aut-name=SogaYoshihiko en-aut-sei=Soga en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoTakashi en-aut-sei=Saito en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishimuraFusanori en-aut-sei=Nishimura en-aut-mei=Fusanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshimaruFumihiko en-aut-sei=Ishimaru en-aut-mei=Fumihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MineshibaJunji en-aut-sei=Mineshiba en-aut-mei=Junji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MineshibaFumi en-aut-sei=Mineshiba en-aut-mei=Fumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakayaHirokazu en-aut-sei=Takaya en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SatoHideaki en-aut-sei=Sato en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KudoChieko en-aut-sei=Kudo en-aut-mei=Chieko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KokeguchiSusumu en-aut-sei=Kokeguchi en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= en-aut-name=TanimotoMitsune en-aut-sei=Tanimoto en-aut-mei=Mitsune kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 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 Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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 Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pathophysiology – Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pathophysiology – Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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= affil-num=9 en-affil=Department of Pathophysiology – Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Global Health and Environmental Sciences – Oral Microbiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Pathophysiology – Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=bacteria kn-keyword=bacteria en-keyword=drug resistance kn-keyword=drug resistance en-keyword=gingiva kn-keyword=gingiva en-keyword=leukemia kn-keyword=leukemia en-keyword=opportunistic infections kn-keyword=opportunistic infections END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=1 article-no= start-page=e651 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Incidence and characteristics of medical emergencies related to dental treatment: a retrospective single-center study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim: Although uncommon, medical emergencies arise in general dental practice. Inadequate data on their severity and frequency makes targeting medical education for general dental practitioners difficult. This also makes planning for unexpected events challenging for practitioners and makes collaborating with emergency physicians burdensome. We aimed to clarify the incidence and characteristics of a dental outpatient department's medical emergencies. Methods: This single-center, retrospective, observational study was undertaken with patients who visited the dental outpatient department of Okayama University Hospital during the 8-year period. The primary outcome of the study was to identify the incidence and characteristics of medical emergencies in the dental outpatient department. Then we examined the timing of medical emergencies, administered medications, and final disposition (home/admission). Results: During the period, 1,146,929 patients were enrolled. Forty-two patients (0.0037%) were consulted as medical emergencies. More than 60% of the incidents were vasovagal syncope, and dehydration and hypoglycemia were the second most prevalent at 9.5%. The most common types of dental treatments were tooth extraction (45.2%), followed by general dental treatment (28.6%), and other dental surgery such as implant placement (14.3%). Types of medical emergencies occurred equally before, during, and after dental treatment. Antihypertensive agents, sedatives, or glucose were used. For patients with emergencies, 90.5% recovered during the day and returned home, and 9.5% were hospitalized. Conclusion: The incidence of medical emergencies was low in our dental outpatient department. Knowledge of basic management principles, regular education for emergency care, and practicing first aid skills are mandatory for safe patient management. en-copyright= kn-copyright= en-aut-name=ObataKyoichi en-aut-sei=Obata en-aut-mei=Kyoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=YakushijiHiromasa en-aut-sei=Yakushiji en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 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=6 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamadaTaihei en-aut-sei=Yamada en-aut-mei=Taihei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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=10 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 Oral and Maxillofacial Surgery 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, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Oral and Maxillofacial Surgery kn-affil= affil-num=10 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Dental treatment kn-keyword=Dental treatment en-keyword=medical emergency kn-keyword=medical emergency en-keyword=vasovagal syncope kn-keyword=vasovagal syncope END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e1675 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genetic analysis in Japanese patients with osteogenesis imperfecta: Genotype and phenotype spectra in 96 probands en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Osteogenesis imperfecta (OI) is a rare connective-tissue disorder characterized by bone fragility. Approximately 90% of all OI cases are caused by variants in COL1A1 or COL1A2. Additionally, IFITM5 variants are responsible for the unique OI type 5. We previously analyzed COL1A1/2 variants in 22 Japanese families with OI through denaturing high-performance liquid chromatography screening, but our detection rate was low (41%). Methods To expand the genotype-phenotype correlations, we performed a genetic analysis of COL1A1/2 and IFITM5 in 96 non-consanguineous Japanese OI probands by Sanger sequencing. Results Of these individuals, 54, 41, and 1 had type 1 (mild), type 2-4 (moderate-to-severe), and type 5 phenotypes, respectively. In the mild group, COL1A1 nonsense and splice-site variants were prevalent (n = 30 and 20, respectively), but there were also COL1A1 and COL1A2 triple-helical glycine substitutions (n = 2 and 1, respectively). In the moderate-to-severe group, although COL1A1 and COL1A2 glycine substitutions were common (n = 14 and 18, respectively), other variants were also detected. The single case of type 5 had the characteristic c.-14C>T variant in IFITM5. Conclusion These results increase our previous detection rate for COL1A1/2 variants to 99% and provide insight into the genotype-phenotype correlations in OI. en-copyright= kn-copyright= en-aut-name=HiguchiYousuke en-aut-sei=Higuchi en-aut-mei=Yousuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HasegawaKosei en-aut-sei=Hasegawa en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FutagawaNatsuko en-aut-sei=Futagawa en-aut-mei=Natsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamashitaMiho en-aut-sei=Yamashita en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaHiroyuki en-aut-sei=Tanaka en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Faculty of Human Life Sciences, Notre Dame Seishin University kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama Saiseikai General Hospital kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=COL1A1 kn-keyword=COL1A1 en-keyword=COL1A2 kn-keyword=COL1A2 en-keyword=IFITM5 kn-keyword=IFITM5 en-keyword=Osteogenesis imperfecta kn-keyword=Osteogenesis imperfecta en-keyword=variant kn-keyword=variant END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e13312 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202153 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Roles of Porphyromonas gulae proteases in bacterial and host cell biology en-subtitle= kn-subtitle= en-abstract= kn-abstract=Porphyromonas gulae, an animal-derived periodontal pathogen, expresses several virulence factors, including fimbria, lipopolysaccharide (LPS) and proteases. We previously reported that its invasive efficiency was dependent on fimbriae types. In addition, P. gulae LPS increased inflammatory responses via toll-like receptors. The present study was conducted to investigate the involvement of P. gulae proteases in bacterial and host cell biology. Porphyromonas gulae strains showed an ability to agglutinate mouse erythrocytes and also demonstrated co-aggregation with Actinomyces viscosus, while the protease inhibitors antipain, PMSF, TLCK and leupeptin diminished P. gulae proteolytic activity, resulting in inhibition of haemagglutination and co-aggregation with A. viscosus. In addition, specific proteinase inhibitors were found to reduce bacterial cell growth. Porphyromonas gulae inhibited Ca9-22 cell proliferation in a multiplicity of infection- and time-dependent manner. Additionally, P. gulae-induced decreases in cell contact and adhesion-related proteins were accompanied by a marked change in cell morphology from well spread to rounded. In contrast, inhibition of protease activity prevented degradation of proteins, such as E-cadherin, beta-catenin and focal adhesion kinase, and also blocked inhibition of cell proliferation. Together, these results indicate suppression of the amount of human proteins, such as gamma-globulin, fibrinogen and fibronectin, by P. gulae proteases, suggesting that a novel protease complex contributes to bacterial virulence. en-copyright= kn-copyright= en-aut-name=UrmiAlam Saki en-aut-sei=Urmi en-aut-mei=Alam Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=InabaHiroaki en-aut-sei=Inaba en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NomuraRyota en-aut-sei=Nomura en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaShoko en-aut-sei=Yoshida en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OharaNaoya en-aut-sei=Ohara en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AsaiFumitoshi en-aut-sei=Asai en-aut-mei=Fumitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakanoKazuhiko en-aut-sei=Nakano en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=Matsumoto‐NakanoMichiyo en-aut-sei=Matsumoto‐Nakano en-aut-mei=Michiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Oral Microbiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and the Advanced Research Center for Oral and Craniofacial Sciences, Dental School, Okayama University kn-affil= affil-num=6 en-affil=Department of Pharmacology, School of Veterinary Medicine Azabu University kn-affil= affil-num=7 en-affil=Department of Pediatric Dentistry, Osaka University Graduate School of Dentistry kn-affil= affil-num=8 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=coaggregation kn-keyword=coaggregation en-keyword=haemagglutination kn-keyword=haemagglutination en-keyword=P. gulae kn-keyword=P. gulae en-keyword=protease kn-keyword=protease en-keyword=protein degradation kn-keyword=protein degradation END start-ver=1.4 cd-journal=joma no-vol=231 cd-vols= no-issue=1 article-no= start-page=75 end-page=84 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Divergence in red light responses associated with thermal reversion of phytochrome B between high‐ and low‐latitude species en-subtitle= kn-subtitle= en-abstract= kn-abstract=Summary
・Phytochromes play a central role in mediating adaptive responses to light and temperature throughout plant life cycles. Despite evidence for adaptive importance of natural variation in phytochromes, little information is known about molecular mechanisms that modulate physiological responses of phytochromes in nature.
・We show evolutionary divergence in physiological responses relevant to thermal stability of a physiologically active form of phytochrome (Pfr) between two sister species of Brassicaceae growing at different latitudes.
The higher latitude species (Cardamine bellidifolia; Cb) responded more strongly to light‐limited conditions compared with its lower latitude sister (C. nipponica; Cn). Moreover, CbPHYB conferred stronger responses to both light‐limited and warm conditions in the phyB‐deficient mutant of Arabidopsis thaliana than CnPHYB: that is Pfr CbphyB was more stable in nuclei than CnphyB.
・Our findings suggest that fine tuning Pfr stability is a fundamental mechanism for plants to optimise phytochrome‐related traits in their evolution and adapt to spatially varying environments, and open a new avenue to understand molecular mechanisms that fine tune phytochrome responses in nature. en-copyright= kn-copyright= en-aut-name=IkedaHajime en-aut-sei=Ikeda en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiTomomi en-aut-sei=Suzuki en-aut-mei=Tomomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkaYoshito en-aut-sei=Oka en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GustafssonA.

Stimulation of iNKT cells by alpha-GC leads to the production of not only immune-stimulatory cytokines but also immune-regulatory cytokines followed by regulatory T-cell (Treg) expansion in vivo. Methods: We investigated the effect of iNKT stimulation by liposomal alpha-GC just after transplant on the subsequent immune reconstitution and the development of sclerodermatous cGVHD. Results: Our study showed that multiple administrations of liposomal alpha-GC modulated both host- and donor-derived iNKT cell homeostasis and induced an early expansion of donor Tregs. We also demonstrated that the immune modulation of the acute phase was followed by the decreased levels of CXCL13 in plasma and follicular helper T cells in lymph nodes, which inhibited germinal center formation, resulting in the efficient prevention of sclerodermatous cGVHD. Conclusions: These data demonstrated an important coordination of T- and B-cell immunity in the pathogenesis of cGVHD and may provide a novel clinical strategy for the induction of immune tolerance after allogeneic HSCT. en-copyright= kn-copyright= en-aut-name=SugiuraHiroyuki en-aut-sei=Sugiura en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=FukumiTakuya en-aut-sei=Fukumi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SumiiYuichi en-aut-sei=Sumii en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KondoTakumi en-aut-sei=Kondo en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IkegawaShuntaro en-aut-sei=Ikegawa en-aut-mei=Shuntaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MeguriYusuke en-aut-sei=Meguri en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IwamotoMiki en-aut-sei=Iwamoto en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SandoYasuhisa en-aut-sei=Sando en-aut-mei=Yasuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakamuraMakoto en-aut-sei=Nakamura en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TojiTomohiro en-aut-sei=Toji en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=IshiiYasuyuki en-aut-sei=Ishii en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 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= affil-num=11 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=12 en-affil=REGiMMUNE Corporation kn-affil= affil-num=13 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=chronic graft-versus-host disease kn-keyword=chronic graft-versus-host disease en-keyword=hematopoietic stem cell transplantation kn-keyword=hematopoietic stem cell transplantation en-keyword=iNKT cells kn-keyword=iNKT cells en-keyword=regulatory T cells kn-keyword=regulatory T cells en-keyword=Tfh cells kn-keyword=Tfh cells en-keyword=alpha-galactosylceramide kn-keyword=alpha-galactosylceramide END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=4 article-no= start-page=1157 end-page=1169 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=HIF-1 alpha controls palatal wound healing by regulating macrophage motility via S1P/S1P(1) signaling axis kn-title=HIF‐1α controls palatal wound healing by regulating macrophage motility via S1P/S1P1 signaling axis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives
To investigate the role of hypoxia-inducible factor 1 alpha (HIF-1 alpha) signaling, the expression profile of M1 and M2 macrophages, and the role of the sphingosine 1-phosphate (S1P)/S1P receptor system in palatal wound healing of heterozygous HIF-1 alpha-deficient (HIF-1 alpha HET) mice. Materials and methods HIF-1 alpha HET and wild-type (WT) littermates underwent palatal tissue excision at the mid-hard palate. Histological analysis, immunostaining, real-time PCR, Western blotting (WB), and cellular migration assays were performed to analyze wound closure and macrophage infiltration.

Results
DMOG pretreatment showed an acceleration of palatal wound closure in WT mice. In contrast, the delayed palatal wound closure was observed in HIF-1 alpha HET mice with diminished production of Col1a1, MCP-1, and MIP-1 alpha, compared with WT mice. Decreased infiltration of M1 macrophage (F4/80(+)TNF-alpha(+), F4/80(+)iNOS(+)) and M2 macrophage (F4/80(+)Arginase-1(+), F4/80(+)CD163(+)) was observed. The numbers of F4/80(+)S1P(1)(+) macrophages of HIF-1 alpha HET wounded tissues were significantly lower compared with WT tissues. S1P treatment of bone marrow macrophages (BMMs) significantly upregulated expression of S1P(1) in WT mice compared with HIF-1 alpha HET. Phosphorylation of MAPK rapidly decreased in BMMs of HIF-1 alpha HET mice than in BMMs of WT mice by S1P stimulation. Moreover, S1P enhanced HIF-1 alpha expression via S1P(1) receptors to affect macrophage migration.

Conclusions
HIF-1 alpha deficiency aggravates M1 and M2 macrophage infiltration and controls macrophage motility via S1P/S1P(1) signaling. These results suggest that HIF-1 alpha signaling may contribute to the regulation of palatal wound healing. en-copyright= kn-copyright= en-aut-name=HutamiIslamy Rahma en-aut-sei=Hutami en-aut-mei=Islamy Rahma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IzawaTakashi en-aut-sei=Izawa en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Khurel‐OchirTsendsuren en-aut-sei=Khurel‐Ochir en-aut-mei=Tsendsuren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakamakiTakuma en-aut-sei=Sakamaki en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwasaAkihiko en-aut-sei=Iwasa en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TomitaShuhei en-aut-sei=Tomita en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanakaEiji en-aut-sei=Tanaka en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Orthodontics and Dentofacial Orthopedics Institute of Biomedical Sciences Tokushima University Graduate School Tokushima Japan kn-affil= affil-num=2 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Orthodontics and Dentofacial Orthopedics Institute of Biomedical Sciences Tokushima University Graduate School Tokushima Japan kn-affil= affil-num=4 en-affil=Department of Orthodontics and Dentofacial Orthopedics Institute of Biomedical Sciences Tokushima University Graduate School Tokushima Japan kn-affil= affil-num=5 en-affil=Department of Orthodontics and Dentofacial Orthopedics Institute of Biomedical Sciences Tokushima University Graduate School Tokushima Japan kn-affil= affil-num=6 en-affil=Department of Pharmacology Osaka City University Graduate School of Medicine Osaka Japan kn-affil= affil-num=7 en-affil=Department of Orthodontics and Dentofacial Orthopedics Institute of Biomedical Sciences Tokushima University Graduate School Tokushima Japan kn-affil= en-keyword=HIF-1α kn-keyword=HIF-1α en-keyword=S1P receptor kn-keyword=S1P receptor en-keyword=hypoxia kn-keyword=hypoxia en-keyword=wound healing kn-keyword=wound healing en-keyword=M1/M2 macrophage kn-keyword=M1/M2 macrophage en-keyword=DMOG kn-keyword=DMOG 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=20210303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=RFX1‐mediated CCN3 induction that may support chondrocyte survival under starved conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cellular communication network factor (CCN) family members are multifunctional matricellular proteins that manipulate and integrate extracellular signals. In our previous studies investigating the role of CCN family members in cellular metabolism, we found three members that might be under the regulation of energy metabolism. In this study, we confirmed that CCN2 and CCN3 are the only members that are tightly regulated by glycolysis in human chondrocytic cells. Interestingly, CCN3 was induced under a variety of impaired glycolytic conditions. This CCN3 induction was also observed in two breast cancer cell lines with a distinct phenotype, suggesting a basic role of CCN3 in cellular metabolism. Reporter gene assays indicated a transcriptional regulation mediated by an enhancer in the proximal promoter region. As a result of analyses in silico, we specified regulatory factor binding to the X‐box 1 (RFX1) as a candidate that mediated the transcriptional activation by impaired glycolysis. Indeed, the inhibition of glycolysis induced the expression of RFX1, and RFX1 silencing nullified the CCN3 induction by impaired glycolysis. Subsequent experiments with an anti‐CCN3 antibody indicated that CCN3 supported the survival of chondrocytes under impaired glycolysis. Consistent with these findings in vitro, abundant CCN3 production by chondrocytes in the deep zones of developing epiphysial cartilage, which are located far away from the synovial fluid, was confirmed in vivo. Our present study uncovered that RFX1 is the mediator that enables CCN3 induction upon cellular starvation, which may eventually assist chondrocytes in retaining their viability, even when there is an energy supply shortage. en-copyright= kn-copyright= en-aut-name=MizukawaTomomi en-aut-sei=Mizukawa en-aut-mei=Tomomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishidaTakashi en-aut-sei=Nishida en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AkashiSho en-aut-sei=Akashi en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawataKazumi en-aut-sei=Kawata en-aut-mei=Kazumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KikuchiSumire en-aut-sei=Kikuchi en-aut-mei=Sumire kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KawakiHarumi en-aut-sei=Kawaki en-aut-mei=Harumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakigawaMasaharu en-aut-sei=Takigawa en-aut-mei=Masaharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=KubotaSatoshi en-aut-sei=Kubota en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences Okayama Japan kn-affil= affil-num=4 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences Okayama Japan kn-affil= affil-num=5 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences Okayama Japan kn-affil= affil-num=6 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences Okayama Japan kn-affil= affil-num=7 en-affil=Advanced Research Center for Oral and Craniofacial Sciences, Okayama University Dental School kn-affil= affil-num=8 en-affil=Department of Orthodontics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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=20210107 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=VEGFR2 blockade augments the effects of tyrosine kinase inhibitors by inhibiting angiogenesis and oncogenic signaling in oncogene-driven non-small-cell lung cancers en-subtitle= kn-subtitle= en-abstract= kn-abstract=Molecular agents targeting the epidermal growth factor receptor (EGFR)-, anaplastic lymphoma kinase (ALK)- or c-ros oncogene 1 (ROS1) alterations have revolutionized the treatment of oncogene-driven non-small-cell lung cancer (NSCLC). However, the emergence of acquired resistance remains a significant challenge, limiting the wider clinical success of these molecular targeted therapies. In this study, we investigated the efficacy of various molecular targeted agents, including erlotinib, alectinib, and crizotinib, combined with anti-vascular endothelial growth factor receptor (VEGFR) 2 therapy. The combination of VEGFR2 blockade with molecular targeted agents enhanced the anti-tumor effects of these agents in xenograft mouse models of EGFR-, ALK-, or ROS1-altered NSCLC. The numbers of CD31-positive blood vessels were significantly lower in the tumors of mice treated with an anti-VEGFR2 antibody combined with molecular targeted agents compared with in those of mice treated with molecular targeted agents alone, implying the antiangiogenic effects of VEGFR2 blockade. Additionally, the combination therapies exerted more potent antiproliferative effects in vitro in EGFR-, ALK-, or ROS1-altered NSCLC cells, implying that VEGFR2 inhibition also has direct anti-tumor effects on cancer cells. Furthermore, VEGFR2 expression was induced following exposure to molecular targeted agents, implying the importance of VEGFR2 signaling in NSCLC patients undergoing molecular targeted therapy. In conclusion, VEGFR2 inhibition enhanced the anti-tumor effects of molecular targeted agents in various oncogene-driven NSCLC models, not only by inhibiting tumor angiogenesis but also by exerting direct antiproliferative effects on cancer cells. Hence, combination therapy with anti-VEGFR2 antibodies and molecular targeted agents could serve as a promising treatment strategy for oncogene-driven NSCLC. en-copyright= kn-copyright=

of shear wave elastography for assessment of liver function in patients with heart failure en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims
Liver dysfunction is important for prognosis in heart failure (HF). Shear wave elastography (SWE), which is a novel ultrasound technique for charactering tissues, has been used in liver diseases. However, clinical implication of SWE, including dispersion slope, remains unknown in heart diseases. This study aimed to evaluate the efficacy of SWE assessing liver function in the severity of HF.
Methods and results
We enrolled 316 consecutive patients with or suspected heart diseases, who were classified according to the American College of Cardiology Foundation/American Heart Association stage of HF, including 37 with Stage A, 139 with Stage B, 114 with Stage C, and 26 with Stage D, and 45 normal subjects. Elasticity and dispersion slope of shear wave were assessed according to the HF stage. Elasticity and dispersion slope were not elevated in normal subjects and patients with Stage A. Elasticity was slightly increased from Stage A to Stage C and was remarkably elevated in Stage D (normal: 5.2 ± 1.1 kPa, Stage A: 5.4 ± 1.2 kPa, Stage B: 6.4 ± 1.8 kPa, Stage C: 7.8 ± 3.5 kPa, and Stage D: 17.7 ± 12.7 kPa), whereas dispersion slope was gradually increased from Stage A to Stage D (normal: 9.7 ± 1.7m/s/kHz, Stage A: 10.4 ± 1.6m/s/kHz, Stage B: 11.7 ± 2.4m/s/kHz, Stage C: 13.2 ± 3.4m/s/kHz, and Stage D: 17.6 ± 5.6 m/s/kHz). In the early HF stage, dispersion slope was elevated. In the advanced HF stage, both elasticity and dispersion slope were elevated. Liver function test abnormalities were observed only from Stage C or Stage D.
Conclusions
Dispersion slope could detect early liver damage, and the combination of elasticity and dispersion slope could clarify the progression of liver dysfunction in HF. SWE may be valuable to manage therapeutic strategies in patients with HF. 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=TohNorihisa en-aut-sei=Toh en-aut-mei=Norihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= en-keyword=Shear wave elastography kn-keyword=Shear wave elastography en-keyword=Elasticity kn-keyword=Elasticity en-keyword=Dispersion slope kn-keyword=Dispersion slope en-keyword=Liver dysfunction kn-keyword=Liver dysfunction en-keyword=Heart failure kn-keyword=Heart failure END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue= article-no= start-page=360 end-page=364 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Best practices for the extraction of genomic DNA from formalin‐fixed paraffin‐embedded tumor tissue for cancer genomic profiling tests en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recently, two cancer genomic profiling tests have been approved in Japan and implemented in routine clinical practice: the FDA‐approved FoundationOne CDx test, and the OncoGuide NCC Oncopanel test. The quality and quantity of DNA significantly affects the sequencing results; therefore, preparing a sufficient amount of high‐quality DNA for clinical cancer genomic profiling tests is important. We examined the best practices for the extraction of cancer genomic DNA from formalin‐fixed paraffin‐embedded (FFPE) tumor tissues of pancreatic, lung and colon cancer specimens. We found that the quality of cancer genomic DNA extracted from 10‐μm‐thick FFPE samples improved significantly, compared with that from 4‐μm‐thick FFPE samples, suggesting that 10‐μm‐thick FFPE samples are preferable for clinical cancer genomic profiling tests. For convenience, we created a quick reference table for calculating the required number of FFPE slides. en-copyright= kn-copyright= en-aut-name=InoueHirofumi en-aut-sei=Inoue en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 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=4 ORCID= en-aut-name=MatsuokaHiromi en-aut-sei=Matsuoka en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SanehiraEtsuko en-aut-sei=Sanehira en-aut-mei=Etsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuokaMasashi en-aut-sei=Matsuoka en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YanaiHiroyuki en-aut-sei=Yanai en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=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=Clinical Genomic Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Science kn-affil= affil-num=2 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital 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 Pathology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Clinical Genomic Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Science 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 Science kn-affil= en-keyword=cancer genomic profiling tests kn-keyword=cancer genomic profiling tests en-keyword=formalin‐fixed paraffin‐embedded (FFPE) tumor tissue kn-keyword=formalin‐fixed paraffin‐embedded (FFPE) tumor tissue en-keyword= genomic DNA extraction kn-keyword= genomic DNA extraction END start-ver=1.4 cd-journal=joma no-vol=158 cd-vols= no-issue= article-no= start-page=233 end-page=245 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201215 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Phosphatidylinositol‐3 kinase mediates the sweet suppressive effect of leptin in mouse taste cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Leptin is known to selectively suppress neural and taste cell responses to sweet compounds. The sweet suppressive effect of leptin is mediated by the leptin receptor Ob‐Rb, and the ATP‐gated K+ (KATP) channel expressed in some sweet‐sensitive, taste receptor family 1 member 3 (T1R3)‐positive taste cells. However, the intracellular transduction pathway connecting Ob‐Rb to KATP channel remains unknown. Here we report that phosphoinositide 3‐kinase (PI3K) mediates leptin's suppression of sweet responses in T1R3‐positive taste cells. In in situ taste cell recording, systemically administrated leptin suppressed taste cell responses to sucrose in T1R3‐positive taste cells. Such leptin's suppression of sucrose responses was impaired by co‐administration of PI3K inhibitors (wortmannin or LY294002). In contrast, co‐administration of signal transducer and activator of transcription 3 inhibitor (Stattic) or Src homology region 2 domain‐containing phosphatase‐2 inhibitor (SHP099) had no effect on leptin's suppression of sucrose responses, although signal transducer and activator of transcription 3 and Src homology region 2 domain‐containing phosphatase‐2 were expressed in T1R3‐positive taste cells. In peeled tongue epithelium, phosphatidylinositol (3,4,5)‐trisphosphate production and phosphorylation of AKT by leptin were immunohistochemically detected in some T1R3‐positive taste cells but not in glutamate decarboxylase 67‐positive taste cells. Leptin‐induced phosphatidylinositol (3,4,5)‐trisphosphate production was suppressed by LY294002. Thus, leptin suppresses sweet responses of T1R3‐positive taste cells by activation of Ob‐Rb–PI3K–KATP channel pathway. en-copyright= kn-copyright= en-aut-name=YoshidaRyusuke en-aut-sei=Yoshida en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MargolskeeRobert F. en-aut-sei=Margolskee en-aut-mei=Robert F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NinomiyaYuzo en-aut-sei=Ninomiya en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Monell Chemical Senses Center kn-affil= affil-num=3 en-affil=Monell Chemical Senses Center kn-affil= en-keyword=energy homeostasis kn-keyword=energy homeostasis en-keyword=leptin signaling kn-keyword=leptin signaling en-keyword=metabolic sensor kn-keyword=metabolic sensor en-keyword=obesity kn-keyword=obesity en-keyword=sweet receptor cell kn-keyword=sweet receptor cell END start-ver=1.4 cd-journal=joma no-vol=238 cd-vols= no-issue=6 article-no= start-page=1341 end-page=1354 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202119 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Expression of SARS‐CoV‐2 entry factors in human oral tissue en-subtitle= kn-subtitle= en-abstract= kn-abstract=The distribution of cells expressing SARS‐CoV‐2 entry factor angiotensin‐converting enzyme 2 (ACE2) and transmembrane serine protease 2 (TMPRSS2) in human oral tissues were tested. The investigation was conducted with normal flesh tissue and paraffin‐embedded specimens. The ACE2 and TMPRSS2 expression was detected with all subjects in the normal mucosa of the keratinized stratified squamous epithelia of the tongue and non‐keratinized stratified squamous epithelia of the lip and cheek. It was found that ACE2 is expressed in the cytoplasm and on the cell membrane mainly in the stratum granulosum of the epithelia while the TMPRSS2 is strongly expressed on the cell membrane mainly in the stratum granulosum and stratum spinosum, but not in the stratum basale. Antibodies’ reactions for ACE2 and TMPRSS2 were not observed in the nuclei or keratin layer. The expression of ACE2 and TMPRSS2 in the oral epithelia appears to be general, and the expression was also observed in the mucous and serous acini of the labial glands. The SARS‐CoV‐2 may transiently attach to the oral mucosa and the minor salivary glands which are present under all of the oral mucosa. The oral cavity can be considered an important organ for SARS‐CoV‐2 attachment and may provide a preventive medical avenue to guard against COVID‐19 by preventing saliva from scattering. en-copyright= kn-copyright= en-aut-name=SawaYoshihiko en-aut-sei=Sawa en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=OkuiTatsuo en-aut-sei=Okui en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamashitaJunro en-aut-sei=Yamashita en-aut-mei=Junro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IkebeTetsuro en-aut-sei=Ikebe en-aut-mei=Tetsuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HaradaHiroyuki en-aut-sei=Harada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Oral Function & Anatomy, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Center for Regenerative Medicine, Fukuoka Dental College kn-affil= affil-num=5 en-affil=Department of Oral and Maxillofacial Surgery, Fukuoka Dental College kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Surgery, Tokyo Medical and Dental University kn-affil= en-keyword=oral tissues kn-keyword=oral tissues en-keyword=SARS‐CoV‐2 kn-keyword=SARS‐CoV‐2 END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=2 article-no= start-page=166 end-page=170 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201214 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A new telestroke network system in northern area of Okayama prefecture en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Telestroke network can provide rapid access to specialized treatment and improves on‐site management of acute stroke patients through the “hub‐and‐spoke” model. In the northern part of Okayama Prefecture, there has been a regional gap of stroke care due to the shortage of stroke specialists and facilities. In addition, due to the novel coronavirus disease 2019 (COVID‐19), it is required to reduce the unnecessary contact with stroke patients from other hospitals.
Aim
We organized a novel cost‐free telestroke network with an image and video sharing for neurological diseases in the northern part of Okayama Prefecture to improve the stroke management in the area.
Method
We prepared the tablet device on which Skype® application was installed for each hospital and recruited the patients who visited or hospitalized in the spoke hospitals and were suspected to have some neurological diseases from April 2019 to May 2020. The patient's clinical data were recorded and analyzed.
Results
During the study period, 5 patients were recruited including the cases with the initial diagnosis of stroke or brain tumor. Among them, 2 cases were transferred to the hub hospital, 2 cases were transferred to other hospitals, and 1 case was treated on site under specialist's advice.
Conclusion
The new telestroke network system may be beneficial for acute stroke management and reducing the unnecessary patient's transfer in the rural area, especially under coexistence with COVID‐19. en-copyright= kn-copyright= en-aut-name=SasakiRyo en-aut-sei=Sasaki en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=OmoteYoshio en-aut-sei=Omote en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakemotoMami en-aut-sei=Takemoto en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=YunokiTaijun en-aut-sei=Yunoki en-aut-mei=Taijun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=SawataTakashi en-aut-sei=Sawata en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SatoYuki en-aut-sei=Sato en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KubotaJunichi en-aut-sei=Kubota en-aut-mei=Junichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MizobuchiMasayuki en-aut-sei=Mizobuchi en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HayashiTakashi en-aut-sei=Hayashi en-aut-mei=Takashi 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=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Neurology, Tsuyama Central Hospital kn-affil= affil-num=7 en-affil=Department of Neurosurgery, Tsuyama Central Hospital kn-affil= affil-num=8 en-affil=Department of Gastrointestinal Surgery, Tsuyama 1st Hospital kn-affil= affil-num=9 en-affil=Department of Internal Medicine, Sato Memorial Hospital kn-affil= affil-num=10 en-affil=Department of Internal Medicine, Tajiri Hospital kn-affil= affil-num=11 en-affil=Department of Neurosurgery, Kaneda Hospital kn-affil= affil-num=12 en-affil=Department of Orthopedics, Sayo Central Hospital kn-affil= affil-num=13 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=COVID‐19 kn-keyword=COVID‐19 en-keyword=Okayama kn-keyword=Okayama en-keyword=skype kn-keyword=skype en-keyword=telemedicine kn-keyword=telemedicine en-keyword=telestroke kn-keyword=telestroke END start-ver=1.4 cd-journal=joma no-vol=529 cd-vols= no-issue= article-no= start-page=2484 end-page=2516 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210111 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Opsin 3/Teleost multiple tissue opsin system: mRNA localization in the retina and brain of medaka (Oryzias latipes) en-subtitle= kn-subtitle= en-abstract= kn-abstract=The photoreceptor protein, opsin, is one of the major components for vision and photoreceptive function in animals. Although many opsins have been discovered from animal genomes, only a few nonimage‐forming functions mediated by opsins have been identified. Understanding the mRNA distribution of photoreceptor proteins is one crucial step in uncovering their photoreceptive function in animals. Here, we focus on the medaka fish (Oryzias latipes) Opsin 3 (Opn3)/Teleost multiple opsin (Tmt) system, which constitutes a separate phylogenetic group, having putative blue light photoreceptors for nonimage‐forming functions. In medaka, there is one opn3 and five tmt‐opsin orthologs. The expression pattern of the opn3/tmt‐opsins in the retina and brain was investigated by in situ hybridization. mRNAs for opn3/tmt‐opsins were distributed in the retinal ganglion cells as well as interneurons and specific brain nuclei. Specifically, hybridization signals were observed in the glutamate decarboxylase 1 (gad1)‐expressing amacrine cells for opn3, tmt1a, tmt1b, and tmt2, in the caudal lobe of the cerebellum for tmt1b and tmt2, in the cranial nerve nuclei for opn3, tmt1a, tmt1b, tmt2, and in the rostral pars distalis (adenohypophysis) for opn3. These expression patterns suggest that blue light sensing in the fish retina and brain may be involved in the integration of visual inputs, vestibular function, somatosensation, motor outputs, and pituitary endocrine regulation. 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=NweKhine Nwe en-aut-sei=Nwe en-aut-mei=Khine Nwe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= affil-num=1 en-affil=Department of Cytology and Histology, Graduate School 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 Cytology and Histology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=medaka kn-keyword=medaka en-keyword=nonimage‐forming photoreception kn-keyword=nonimage‐forming photoreception en-keyword=opn3 kn-keyword=opn3 en-keyword=opsin kn-keyword=opsin en-keyword=tmt‐opsin kn-keyword=tmt‐opsin en-keyword=RRID:SCR_018163 kn-keyword=RRID:SCR_018163 en-keyword=RRID:SCR_003070 kn-keyword=RRID:SCR_003070 en-keyword=RRID:SCR_005887 kn-keyword=RRID:SCR_005887 en-keyword=RRID:SCR_004860 kn-keyword=RRID:SCR_004860 en-keyword=RRID:SCR_010279 kn-keyword=RRID:SCR_010279 en-keyword=RRID:AB_2336524 kn-keyword=RRID:AB_2336524 en-keyword=RRID:AB_514497 kn-keyword=RRID:AB_514497 en-keyword=RRID:AB_514504 kn-keyword=RRID:AB_514504 en-keyword=RRID:AB_2339038 kn-keyword=RRID:AB_2339038 en-keyword=RRID: AB_840257 kn-keyword=RRID: AB_840257 END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=3 article-no= start-page=1810 end-page=1811 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210126 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Simultaneous hot and cold thyroid nodules: Which is malignant? en-subtitle= kn-subtitle= en-abstract= kn-abstract=Physicians should be aware of the risk of malignancy in patients with toxic multinodular goiter.

The rank-based ant system (AS(rank)) has been proposed as a developed version of the fundamental model AS of ACO. In the AS(rank), since only ant agents that have found one of some excellent solutions are let to regulate the pheromone, the pheromone concentrates on a specific route. As a result, although the AS(rank) can find a relatively good solution in a short time, it has the disadvantage of being prone falling into a local solution because the pheromone concentrates on a specific route. This problem seems to come from the loss of diversity in route selection according to the rapid accumulation of pheromones to the specific routes. Some ACO models, not just the AS(rank), also suffer from this problem of loss of diversity in route selection. It can be considered that the diversity of solutions as well as the selection of solutions is an important factor in the solution system by swarm intelligence such as ACO. In this paper, to solve this problem, we introduce the ant system using individual memories (ASIM) aiming to improve the ability to solve TSP while maintaining the diversity of the behavior of each ant. We apply the existing ACO algorithms and ASIM to some TSP benchmarks and compare the ability to solve TSP. en-copyright= kn-copyright= en-aut-name=TamuraYoshiki en-aut-sei=Tamura en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakiyamaTomoko en-aut-sei=Sakiyama en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ArizonoIkuo en-aut-sei=Arizono en-aut-mei=Ikuo 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=Department of Information Systems Science, Faculty of Science and Engineering, Soka University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=8 article-no= start-page=1249 end-page=1263 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20180731 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genotoxic stress induces Sca‐1‐expressing metastatic mammary cancer cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=We describe a cell damage‐induced phenotype in mammary carcinoma cells involving acquisition of enhanced migratory and metastatic properties.

Vision and touch are thought to contribute information to object perception in an independent but complementary manner. The left lateral posterior parietal cortex (LPPC) has long been associated with multisensory information processing, and it plays an important role in visual and haptic crossmodal information retrieval. However, it remains unclear how LPPC subregions are involved in visuo‐haptic crossmodal retrieval processing.
Methods
In the present study, we used an fMRI experiment with a crossmodal delayed match‐to‐sample paradigm to reveal the functional role of LPPC subregions related to unimodal and crossmodal dot‐surface retrieval.
Results
The visual‐to‐haptic condition enhanced the activity of the left inferior parietal lobule relative to the haptic unimodal condition, whereas the inverse condition enhanced the activity of the left superior parietal lobule. By contrast, activation of the left intraparietal sulcus did not differ significantly between the crossmodal and unimodal conditions. Seed‐based resting connectivity analysis revealed that these three left LPPC subregions engaged distinct networks, confirming their different functions in crossmodal retrieval processing.
Conclusion
Taken together, the findings suggest that functional heterogeneity of the left LPPC during visuo‐haptic crossmodal dot‐surface retrieval processing reflects that the left LPPC does not simply contribute to retrieval of past information; rather, each subregion has a specific functional role in resolving different task requirements. en-copyright= kn-copyright= en-aut-name=YangJiajia en-aut-sei=Yang en-aut-mei=Jiajia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=ShigemasuHiroaki en-aut-sei=Shigemasu en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KadotaHiroshi en-aut-sei=Kadota en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakaharaKiyoshi en-aut-sei=Nakahara en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KochiyamaTakanori en-aut-sei=Kochiyama en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 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=Kochi University of Technology kn-affil= affil-num=4 en-affil=Kochi University of Technology kn-affil= affil-num=5 en-affil=Kochi University of Technology kn-affil= affil-num=6 en-affil=ATR Brain Activity Imaging Center 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=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=crossmodal processing kn-keyword=crossmodal processing en-keyword=fMRI kn-keyword=fMRI en-keyword=haptic dot-surface matching kn-keyword=haptic dot-surface matching en-keyword=lateral posterior parietal cortex kn-keyword=lateral posterior parietal cortex en-keyword=memory retrieval kn-keyword=memory retrieval END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=5 article-no= start-page=643 end-page=649 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Crizotinib for recurring non-small-cell lung cancer with EML4-ALK fusion genes previously treated with alectinib: A phase II trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
The efficacy of crizotinib treatment for recurring EML4‐ALK‐positive non‐small cell lung cancer (NSCLC) previously treated with alectinib is unclear. Based on our preclinical findings regarding hepatocyte growth factor/mesenchymal epithelial transition (MET) pathway activation as a potential mechanism of acquired resistance to alectinib, we conducted a phase II trial of the anaplastic lymphoma kinase/MET inhibitor, crizotinib, in patients with alectinib‐refractory, EML4‐ALK‐positive NSCLC.
Methods
Patients with ALK‐rearranged tumors treated with alectinib immediately before enrolling in the trial received crizotinib monotherapy. The objective response rate was the primary outcome of interest.
Results
Nine (100%) patients achieved a partial response with alectinib therapy with a median treatment duration of 6.7 months. Crizotinib was administered with a median treatment interval of 50 (range, 20–433) days. The overall response rate was 33.3% (90% confidence interval [CI]: 9.8–65.5 and 95% CI: 7.5–70.1), which did not reach the predefined criteria of 50%. Two (22%) patients who achieved a partial response had brain metastases at baseline. Progression‐free survival (median, 2.2 months) was not affected by the duration of treatment with alectinib. The median survival time was 24.1 months. The most common adverse events were an increased aspartate transaminase/alanine transaminase (AST/ALT) ratio (44%) and appetite loss (33%); one patient developed transient grade 4 AST/ALT elevation, resulting in treatment discontinuation. Other adverse events were consistent with those previously reported; no treatment‐related deaths occurred.
Conclusions
Although the desired response rate was not achieved, crizotinib monotherapy following treatment with alectinib showed efficacy alongside previously described adverse events. en-copyright= kn-copyright= en-aut-name=HaradaDaijiro en-aut-sei=Harada en-aut-mei=Daijiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IsozakiHideko en-aut-sei=Isozaki en-aut-mei=Hideko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=YokoyamaToshihide en-aut-sei=Yokoyama en-aut-mei=Toshihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshiokaHiroshige en-aut-sei=Yoshioka en-aut-mei=Hiroshige kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=BesshoAkihiro en-aut-sei=Bessho en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HosokawaShinobu en-aut-sei=Hosokawa en-aut-mei=Shinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakataIchiro en-aut-sei=Takata en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakigawaNagio en-aut-sei=Takigawa en-aut-mei=Nagio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=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=Okayama Lung Cancer Study Group en-aut-sei=Okayama Lung Cancer Study Group en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Thoracic Oncology, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=2 en-affil=Department of Clinical Pharmaceutics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Thoracic Oncology, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=4 en-affil=Department of Respiratory Medicine, Kurashiki Central Hospital kn-affil= affil-num=5 en-affil=Department of Respiratory Medicine, Kurashiki Central Hospital kn-affil= affil-num=6 en-affil=Department of Respiratory Medicine, Japanese Red Cross Okayama Hospital kn-affil= affil-num=7 en-affil=Department of Respiratory Medicine, Japanese Red Cross Okayama Hospital kn-affil= affil-num=8 en-affil=Department of Internal Medicine, Fukuyama City Hospital kn-affil= affil-num=9 en-affil= kn-affil= affil-num=10 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=12 en-affil= kn-affil= en-keyword=Alectinib kn-keyword=Alectinib en-keyword=anaplastic lymphoma kinase kn-keyword=anaplastic lymphoma kinase en-keyword=crizotinib kn-keyword=crizotinib en-keyword=drug therapy kn-keyword=drug therapy en-keyword=non-small cell lung carcinoma kn-keyword=non-small cell lung carcinoma END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=4 article-no= start-page=811 end-page=830 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200415 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Factors associated with development and distribution of granular/fuzzy astrocytes in neurodegenerative diseases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Granular/fuzzy astrocytes (GFAs), a subtype of “aging‐related tau astrogliopathy,” are noted in cases bearing various neurodegenerative diseases. However, the pathogenic significance of GFAs remains unclear. We immunohistochemically examined the frontal cortex, caudate nucleus, putamen and amygdala in 105 cases composed of argyrophilic grain disease cases (AGD, N = 26), and progressive supranuclear palsy (PSP, N = 10), Alzheimer’s disease (AD, N = 20) and primary age‐related tauopathy cases (PART, N = 18) lacking AGD, as well as 31 cases bearing other various neurodegenerative diseases to clarify (i) the distribution patterns of GFAs in AGD, and PSP, AD and PART lacking AGD, (ii) the impacts of major pathological factors and age on GFA formation and (iii) immunohistochemical features useful to understand the formation process of GFAs. In AGD cases, GFAs consistently occurred in the amygdala (100%), followed by the putamen (69.2%) and caudate nucleus and frontal cortex (57.7%, respectively). In PSP cases without AGD, GFAs were almost consistently noted in all regions examined (90–100%). In AD cases without AGD, GFAs were less frequent, developing preferably in the putamen (35.0%) and caudate nucleus (30.0%). PART cases without AGD had GFAs most frequently in the amygdala (35.3%), being more similar to AGD than to AD cases. Ordered logistic regression analyses using all cases demonstrated that the strongest independent factor of GFA formation in the frontal cortex and striatum was the diagnosis of PSP, while that in the amygdala was AGD. The age was not significantly associated with GFA formation in any region. In GFAs in AGD cases, phosphorylation and conformational change of tau, Gallyas‐positive glial threads indistinguishable from those in tufted astrocytes, and the activation of autophagy occurred sequentially. Given these findings, AGD, PSP, AD and PART cases may show distinct distributions of GFAs, which may provide clues to predict the underlying processes of primary tauopathies. en-copyright= kn-copyright= en-aut-name=MikiTomoko en-aut-sei=Miki en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YokotaOsamu en-aut-sei=Yokota en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaraguchiTakashi en-aut-sei=Haraguchi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshizuHideki en-aut-sei=Ishizu en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HasegawaMasato en-aut-sei=Hasegawa en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IshiharaTakeshi en-aut-sei=Ishihara en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UenoShu‐ichi en-aut-sei=Ueno en-aut-mei=Shu‐ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakenoshitaShintaro en-aut-sei=Takenoshita en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TeradaSeishi en-aut-sei=Terada en-aut-mei=Seishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YamadaNorihito en-aut-sei=Yamada en-aut-mei=Norihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurology, National Hospital Organization Minami‐Okayama Medical Center kn-affil= affil-num=4 en-affil=Department of Laboratory Medicine and Pathology, Zikei Institute of Psychiatry kn-affil= affil-num=5 en-affil=Dementia Research Project, Tokyo Metropolitan Institute of Medical Science kn-affil= affil-num=6 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=7 en-affil=Department of Neuropsychiatry, Ehime University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=aging‐related tau astrogliopathy kn-keyword=aging‐related tau astrogliopathy en-keyword=argyrophilic grain kn-keyword=argyrophilic grain en-keyword=granular/fuzzy astrocyte kn-keyword=granular/fuzzy astrocyte en-keyword=primary age‐related tauopathy kn-keyword=primary age‐related tauopathy en-keyword=tau kn-keyword=tau en-keyword=tufted astrocyte kn-keyword=tufted astrocyte END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=1 end-page=11 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200617 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Outcomes of Patients with Pulmonary Atresia with Intact Ventricular Septum Reaching Adulthood en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: There is limited information on outcomes of adult patients with pulmonary atresia with intact ventricular septum (PA-IVS) due to the low incidence of disease and the large variation of surgical histories.

Twenty-four patients had undergone biventricular repair (BVR), 3 had undergone one-and-a half ventricular repair (1.5VR), and 5 had undergone univentricular repair. Over a median follow-up period of 7.7 years (interquartile range: 4.1–11.0 years), 1 BVR patient died suddenly and 7 patients had heart failure. Arrhythmias were present in 5 patients. Ten patients underwent surgical re-interventions, including 4 BVR take-downs with conversion to 1.5VR and 3 Fontan conversions. Overall survival, heart failure-free, arrhythmia-free, and surgical re-intervention-free rates at 5 years and 10 years from the age of 16 years were 96.2% (95% confidence interval [CI], 77.2–99.4) and 96.2% (95% CI, 77.2– 99.4), 81.4% (95% CI, 62.1–92.1) and 74.6% (95%CI, 52.3–88.7), 88.7% (95% CI, 70.1–96.3) and 75.9% (95% CI, 51.7–90.2), and 80.7% (95% CI, 60.8–91.8) and 70.8% (95% CI, 49.7–85.7), respectively. Conclusion: Adults with PA-IVS have preserved long-term survival regardless of the early operative strategy, while they are at risk for heart failure, arrhythmia, and surgical re-intervention. Thus, detailed and continued follow-up is mandatory for all PA-IVS patients from childhood to adulthood. en-copyright= kn-copyright= en-aut-name=TohNorihisa en-aut-sei=Toh en-aut-mei=Norihisa 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=AkagiTeiji en-aut-sei=Akagi en-aut-mei=Teiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=BabaKenji en-aut-sei=Baba en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtsukiShin-ichi en-aut-sei=Otsuki en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=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, 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 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 Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pediatric Cardiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pediatric Cardiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Cardiovascular Surgery, 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= en-keyword=Pulmonary atresia with intact ventricular septum kn-keyword=Pulmonary atresia with intact ventricular septum en-keyword=adult congenital heart disease kn-keyword=adult congenital heart disease en-keyword=outcome kn-keyword=outcome END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=1 article-no= start-page=e618 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Incidence and related factors of hypoxia associated with elderly femoral neck fractures in the emergency department setting en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim
Femoral neck fractures in elderly patients needing oxygen therapy are often encountered in the emergency department. This single‐center, retrospective, observational study aimed to examine the frequency, cause, and factors related to hypoxia in elderly patients with femoral neck fractures.
Methods
We analyzed data from 241 patients admitted to Okayama Saiseikai General Hospital (Okayama, Japan) from April 2016 to March 2019. Hypoxia was defined as PaO2 / FiO2 ratio under 300. The independent factors for hypoxia were determined by multiple logistic regression analysis.
Results
There were 194 patients who met the study inclusion criteria, 148 in the non‐hypoxia group and 46 in the hypoxia group. The hypoxia group included patients with pneumonia (n = 3), chronic obstructive pulmonary disease (n = 2), pulmonary edema (n = 1), and pulmonary embolization (n = 1). The cause of hypoxia was undetermined in 39 cases. However, occult fat embolism syndrome was suspected in 29 of these 39 cases based on Gurd and Wilson criteria after considering clinical examination results. Barthel indexes were significantly lower in the hypoxia group on discharge. Age (adjusted odds ratio [OR] 1.07; 95% confidence interval [CI], 1.00–1.14; P = 0.038), D‐dimer (adjusted OR 1.02; 95% CI, 1.00–1.03; P = 0.005), and transtricuspid pressure gradient (adjusted OR 1.03; 95% CI, 1.00–1.07; P = 0.015) were independently associated with the hypoxia.
Conclusion
We found that hypoxia, including undetermined hypoxia, was commonly encountered in the emergency department. Hypoxia in elderly patients with femoral neck fractures was associated with age, D‐dimer, and transtricuspid pressure gradient and needs further investigation. en-copyright= kn-copyright= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=FujiwaraToshifumi en-aut-sei=Fujiwara en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InabaMototaka en-aut-sei=Inaba en-aut-mei=Mototaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujisakiNoritomo en-aut-sei=Fujisaki en-aut-mei=Noritomo 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= affil-num=1 en-affil=Emergency Department, Okayama Saiseikai General Hospital kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Emergency Department, Okayama Saiseikai General Hospital kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=D-dimer kn-keyword=D-dimer en-keyword=geriatric kn-keyword=geriatric en-keyword=hypoxia kn-keyword=hypoxia en-keyword=injury kn-keyword=injury en-keyword=TRPG kn-keyword=TRPG END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=5 article-no= start-page=725 end-page=731 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Novel prospective umbrella-type lung cancer registry study for clarifying clinical practice patterns: CS-Lung-003 study protocol en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction
Conventional cancer registries are suitable for simple surveillance of cancer patients, including disease frequency and distribution, demographics, and prognosis; however, the collected data are inadequate to clarify comprehensively diverse clinical questions in daily practice.
Methods
We constructed an umbrella‐type lung cancer patient registry (CS‐Lung‐003) integrating multiple related prospective observational studies (linked studies) that reflect clinical questions about lung cancer treatment. The primary endpoint of this registry is to clarify daily clinical practice patterns in lung cancer treatment; a key inclusion criterion is pathologically diagnosed lung cancer. Under this registry, indispensable clinical items are detected in advance across all active linked studies and gathered prospectively and systematically to avoid excessive or insufficient data collection. Researchers are to input information mutually, irrespective of the relevance to each researcher's own study. Linked studies under the umbrella of the CS‐Lung‐003 registry will be updated annually with newly raised clinical questions; some linked studies will be newly created, while others will be deleted after the completion of the analysis. Enrollment began in July 2017.
Discussion
We successfully launched the umbrella‐type CS‐Lung‐003 registry. Under this single registry, researchers collaborate on patient registration and data provision for their own and other studies. Thus, the registry will produce results for multiple domains of study, providing answers to questions about lung cancer treatment raised by other researchers. Through such analysis of each linked study, this registry will contribute to the comprehensive elucidation of actual daily practice patterns in lung cancer treatment.
Key points
CS‐Lung‐003 registry directly integrates multiple linked studies created under the umbrella of this cancer registry to solve various clinical questions regarding daily practice patterns of lung cancer treatment. en-copyright= kn-copyright= en-aut-name=NishiiKazuya en-aut-sei=Nishii en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=InoueMasaaki

and related clinical factors in Japanese patients with diabetes: The Japan Diabetes Complication and its Prevention prospective study 5 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims/Introduction
To clarify the prevalence of albuminuria and renal dysfunction, and related factors in Japanese patients with diabetes, we analyzed the baseline data of the Japan Diabetes Complication and its Prevention prospective study.
Materials and Methods
We used the data of 355 patients with type 1 diabetes and 5,194 patients with type 2 diabetes to evaluate the prevalence of albuminuria and renal dysfunction, and related factors. A binomial logistic regression analysis was used to investigate independent contributing factors for estimated glomerular filtration rate <60 mL/min/1.73 m2 or albuminuria.
Results
The prevalence of microalbuminuria and macroalbuminuria was 15.2% (54/355) and 3.1% (11/355) in type 1 diabetes patients, and 25.0% (1,298/5,194) and 5.1% (265/5,194) in type 2 diabetes patients, respectively. The proportion of renal dysfunction (estimated glomerular filtration rate <60 mL/min/1.73 m2) was 9.9% (35/355) in type 1 diabetes patients, and 15.3% (797/5,194) in type 2 diabetes patients. The proportion of patients with renal dysfunction with normoalbuminuria was 7.3% (26/355) for type 1 diabetes patients, and 9.0% (467/5,194) for type 2 diabetes patients. The factors related to albuminuria in type 2 diabetes patients were glycated hemoglobin, hypertension, age, duration of diabetes, body mass index and estimated glomerular filtration rate. In contrast, factors to related renal dysfunction were age, duration of diabetes, dyslipidemia, hypertension, body mass index, male sex and albuminuria.
Conclusions
We showed the recent prevalence of albuminuria and renal dysfunction, and related factors in Japanese type 1 and type 2 diabetes patients using the baseline data of the Japan Diabetes Complication and its Prevention prospective study. The current results suggest that renal disease in patients with type 2 diabetes is heterogeneous, and different mechanisms might be involved in albuminuria and deterioration of renal function. en-copyright= kn-copyright= en-aut-name=ShikataKenichi en-aut-sei=Shikata en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KoderaRyo en-aut-sei=Kodera en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UtsunomiyaKazunori en-aut-sei=Utsunomiya en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KoyaDaisuke en-aut-sei=Koya en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishimuraRimei en-aut-sei=Nishimura en-aut-mei=Rimei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyamotoSatoshi en-aut-sei=Miyamoto en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TajimaNaoko en-aut-sei=Tajima en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=the JDCP study group en-aut-sei=the JDCP study group en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=The Japan Diabetes Society kn-affil= affil-num=3 en-affil=The Japan Diabetes Society kn-affil= affil-num=4 en-affil=The Japan Diabetes Society kn-affil= affil-num=5 en-affil=The Japan Diabetes Society kn-affil= affil-num=6 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=The Japan Diabetes Society kn-affil= affil-num=8 en-affil= kn-affil= en-keyword=Diabetic nephropathy kn-keyword=Diabetic nephropathy en-keyword=Diabetic kidney disease kn-keyword=Diabetic kidney disease en-keyword=Japan Diabetes Complication and its Prevention study kn-keyword=Japan Diabetes Complication and its Prevention study END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=8 article-no= start-page=e12875 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200523 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Vasopressin gene products are colocalised with corticotrophin‐releasing factor within neurosecretory vesicles in the external zone of the median eminence of the Japanese macaque monkey (Macaca fuscata) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Arginine vasopressin (AVP), when released into portal capillaries with corticotrophin‐releasing factor (CRF) from terminals of parvocellular neurones of the hypothalamic paraventricular nucleus (PVH), facilitates the secretion of adrenocorticotrophic hormone (ACTH) in stressed rodents. The AVP gene encodes a propeptide precursor containing AVP, AVP‐associated neurophysin II (NPII), and a glycopeptide copeptin, although it is currently unclear whether copeptin is always cleaved from the neurophysin and whether the NPII and/or copeptin have any functional role in the pituitary. Furthermore, for primates, it is unknown whether CRF, AVP, NPII and copeptin are all colocalised in neurosecretory vesicles in the terminal region of the paraventricular CRF neurone axons. Therefore, we investigated, by fluorescence and immunogold immunocytochemistry, the cellular and subcellular relationships of these peptides in the CRF‐ and AVP‐producing cells in unstressed Japanese macaque monkeys (Macaca fuscata). Reverse transcription‐polymerase chain reaction analysis showed the expression of both CRF and AVP mRNAs in the monkey PVH. As expected, in the magnocellular neurones of the PVH and supraoptic nucleus, essentially no CRF immunoreactivity could be detected in NPII‐immunoreactive (AVP‐producing) neurones. Immunofluorescence showed that, in the parvocellular part of the PVH, NPII was detectable in a subpopulation (approximately 39%) of the numerous CRF‐immunoreactive neuronal perikarya, whereas, in the outer median eminence, NPII was more prominent (approximately 52%) in the CRF varicosities. Triple immunoelectron microscopy in the median eminence demonstrated the presence of both NPII and copeptin immunoreactivity in dense‐cored vesicles of CRF‐containing axons. The results are consistent with an idea that the AVP propeptide is processed and NPII and copeptin are colocalised in hypothalamic‐pituitary CRF axons in the median eminence of a primate. The CRF, AVP and copeptin are all co‐packaged in neurosecretory vesicles in monkeys and are thus likely to be co‐released into the portal capillary blood to amplify ACTH release from the primate anterior pituitary. en-copyright= kn-copyright= en-aut-name=OtuboAkito en-aut-sei=Otubo en-aut-mei=Akito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawakamiNatsuko en-aut-sei=Kawakami en-aut-mei=Natsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaejimaSho en-aut-sei=Maejima en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UedaYasumasa en-aut-sei=Ueda en-aut-mei=Yasumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MorrisJohn F. en-aut-sei=Morris en-aut-mei=John F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakamotoTatsuya en-aut-sei=Sakamoto en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakamotoHirotaka en-aut-sei=Sakamoto en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Physiology, Kyoto Prefectural University of Medicine kn-affil= affil-num=5 en-affil=Department of Physiology, Anatomy & Genetics, University of Oxford kn-affil= affil-num=6 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=corticotrophin‐releasing factor kn-keyword=corticotrophin‐releasing factor en-keyword=Japanese macaque monkey (Macaca fuscata) kn-keyword=Japanese macaque monkey (Macaca fuscata) en-keyword=median eminence kn-keyword=median eminence en-keyword=paraventricular nucleus of the hypothalamus kn-keyword=paraventricular nucleus of the hypothalamus en-keyword=vasopressin kn-keyword=vasopressin END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=4 article-no= start-page=995 end-page=1008 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=BdWRKY38 is required for the incompatible interaction of Brachypodium distachyon with the necrotrophic fungus Rhizoctonia solani en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rhizoctonia solani is a soil‐borne necrotrophic fungus that causes sheath blight in grasses. The basal resistance of compatible interactions between R. solani and rice is known to be modulated by some WRKY transcription factors (TFs). However, genes and defense responses involved in incompatible interaction with R. solani remain unexplored, because no such interactions are known in any host plants. Recently, we demonstrated that Bd3‐1, an accession of the model grass Brachypodium distachyon, is resistant to R. solani and, upon inoculation with the fungus, undergoes rapid induction of genes responsive to the phytohormone salicylic acid (SA) that encode the WRKY TFs BdWRKY38 and BdWRKY44. Here, we show that endogenous SA and these WRKY TFs positively regulate this accession‐specific R. solani resistance. In contrast to a susceptible accession (Bd21), the infection process in the resistant accessions Bd3‐1 and Tek‐3 was suppressed at early stages before the development of fungal biomass and infection machinery. A comparative transcriptome analysis during pathogen infection revealed that putative WRKY‐dependent defense genes were induced faster in the resistant accessions than in Bd21. A gene regulatory network (GRN) analysis based on the transcriptome dataset demonstrated that BdWRKY38 was a GRN hub connected to many target genes specifically in resistant accessions, whereas BdWRKY44 was shared in the GRNs of all three accessions. Moreover, overexpression of BdWRKY38 increased R. solani resistance in Bd21. Our findings demonstrate that these resistant accessions can activate an incompatible host response to R. solani, and BdWRKY38 regulates this response by mediating SA signaling. en-copyright= kn-copyright= en-aut-name=KouzaiYusuke en-aut-sei=Kouzai en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimizuMinami en-aut-sei=Shimizu en-aut-mei=Minami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InoueKomaki en-aut-sei=Inoue en-aut-mei=Komaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Uehara‐YamaguchiYukiko en-aut-sei=Uehara‐Yamaguchi en-aut-mei=Yukiko 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=NakayamaRisa en-aut-sei=Nakayama en-aut-mei=Risa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuuraTakakazu en-aut-sei=Matsuura en-aut-mei=Takakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MoriIzumi C. en-aut-sei=Mori en-aut-mei=Izumi C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HirayamaTakashi en-aut-sei=Hirayama en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AbdelsalamSobhy S.

Here, it is reported that a biocompatible and tough metal, titanium (Ti), shows instant and remarkable adhesion properties after acid treatment, demonstrated by ex vivo shear adhesion tests with mouse dermal tissues. Importantly, in vivo experiments demonstrate that the acid‐treated Ti can easily and stably immobilize a device implanted in the mouse subcutaneous tissue. Collectively, the acid‐treated Ti is shown as a solid‐state instant adhesive material for biological soft tissues, which can have diverse applications including immobilization of body‐implantable devices. en-copyright= kn-copyright= en-aut-name=OkadaMasahiro en-aut-sei=Okada en-aut-mei=Masahiro 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=Yabetsushi en-aut-sei=Yabe en-aut-mei=tsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkadaKei en-aut-sei=Okada en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShibataYo en-aut-sei=Shibata en-aut-mei=Yo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Torii Yasuhiro en-aut-sei=Torii en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakanoTakayoshi en-aut-sei=Nakano en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Applied Chemistry and Biotechnology, Faculty of Engineering, Okayama University kn-affil= affil-num=5 en-affil=Department of Conservative Dentistry, Division of Biomaterials and Engineering, Showa University School of Dentistry kn-affil= affil-num=6 en-affil=Department of Comprehensive Dentistry, Okayama University Hospital kn-affil= affil-num=7 en-affil=Division of Materials and Manufacturing Science, Graduate School of Engineering, Osaka University kn-affil= affil-num=8 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=acid treatment kn-keyword=acid treatment en-keyword=adhesive kn-keyword=adhesive en-keyword=hydrophobic interaction kn-keyword=hydrophobic interaction en-keyword=soft tissue kn-keyword=soft tissue en-keyword=titanium kn-keyword=titanium END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=2 article-no= start-page=124 end-page=134 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=Utility of gastric biopsy in diagnosing IgG4‐related gastrointestinal disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=The utility of gastric biopsy for diagnosing immunoglobulin (Ig)G4‐related gastrointestinal disease (IgG4‐GID) remains unclear. Bottom‐heavy plasmacytosis (BHP) is a distinct feature of IgG4‐GID. To clarify the feasibility of using gastric biopsies to diagnose BHP in IgG4‐GID, we analyzed the histological features and immunostaining of gastric biopsy specimens from 31 known IgG4‐related disease (IgG4‐RD) patients and we assessed the presence of BHP in 1696 consecutive routine gastric biopsies. Cases with both >10 IgG4‐positive plasma cells per high‐power field and an IgG4/IgG‐positive ratio >40% were defined as IgG4‐high. Ten of the 31 IgG4‐RD patients were concluded to have IgG4‐GID, in which IgG4‐positive plasma cells were notably detected at the deeper part of the mucosa. Six cases displayed BHP whereas the remaining four cases showed transmural infiltration with concomitant Helicobacter pylori‐associated gastritis. In addition to BHP, we identified two unique histologic features for IgG4‐GID: plasmacytic aggregation in the muscularis mucosae and permeative plasmacytic infiltration between fundic glands in the non‐atrophic mucosa. Six of the routine cases (0.35%) displayed BHP, including a case with IgG4‐RD. IgG4‐GID can be suspected by the presence of gastric biopsy specimens with characteristic histological features. Such cases are recommended to undergo further examinations to determine whether IgG4‐RD is present. en-copyright= kn-copyright= en-aut-name=UchinoKaori en-aut-sei=Uchino en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NotoharaKenji en-aut-sei=Notohara en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UeharaTakeshi en-aut-sei=Uehara en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KuraishiYasuhiro en-aut-sei=Kuraishi en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ItakuraJunya en-aut-sei=Itakura en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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 Anatomic Pathology, Kurashiki Central Hospital kn-affil= affil-num=3 en-affil=Department of Laboratory Medicine, Shinshu University School of Medicine kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Shinshu University School of Medicine kn-affil= affil-num=5 en-affil=Department of Anatomic Pathology, Kurashiki Central Hospital kn-affil= affil-num=6 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=biopsy kn-keyword=biopsy en-keyword=feasibility studies kn-keyword=feasibility studies en-keyword=gastric mucosa kn-keyword=gastric mucosa en-keyword=gastritis kn-keyword=gastritis en-keyword=IgG4 kn-keyword=IgG4 en-keyword=IgG4‐related disease kn-keyword=IgG4‐related disease en-keyword=immunoglobulin G4 kn-keyword=immunoglobulin G4 en-keyword=immunohistochemistry kn-keyword=immunohistochemistry en-keyword=plasma cells kn-keyword=plasma cells END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=9 article-no= start-page=585 end-page=592 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200915 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Animal infection models using non‐mammals en-subtitle= kn-subtitle= en-abstract= kn-abstract=The use of non‐human animal models for infection experiments is important for investigating the infectious processes of human pathogenic bacteria at the molecular level.

Various non‐mammalian animal infection models have been used to investigate the molecular mechanisms of various human pathogenic bacteria, including Staphylococcus aureus, Streptococcus pyogenes, and Pseudomonas aeruginosa.

Caffeine is a dopamine activator and thus enhances dopamine receptor activity. However, the effects of caffeine intake on insect mating behavior have been largely unexplored. Therefore, we examined the effect of caffeine on mating behavior in the red flour beetle Tribolium castaneum. Caffeine, which activates dopamine, affected the mating behavior of T. castaneum males. Males who orally ingested caffeine courted faster than males who did not, resulting in faster mounting of females and less time to a male's external aedeagus protrusion. However, the present results showed no difference in sperm precedence measured as a P2 value between males fed caffeine and males not fed caffeine. We discuss the effects of caffeine on insect mating and the possibility that caffeine consumption may cause males to mate with more females in the laboratory. en-copyright= kn-copyright= en-aut-name=JiYuhao en-aut-sei=Ji en-aut-mei=Yuhao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=RyujiYuki en-aut-sei=Ryuji en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=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 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=Faculty of Agriculture, Kagawa University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=mating latency kn-keyword=mating latency en-keyword=mounting behavior kn-keyword=mounting behavior en-keyword=number of mating kn-keyword=number of mating en-keyword=red flour beetle kn-keyword=red flour beetle en-keyword=reproductive success kn-keyword=reproductive success en-keyword=sperm competition kn-keyword=sperm competition END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=23 article-no= start-page=e016907 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201123 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Significance of Exercise-Related Ventricular Arrhythmias in Patients With Brugada Syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Sinus tachycardia during exercise attenuates ST‐segment elevation in patients with Brugada syndrome, whereas ST‐segment augmentation after an exercise test is a high‐risk sign. Some patients have premature ventricular contractions (PVCs) related to exercise, but the significance of exercise‐related PVCs in patients with Brugada syndrome is still unknown. The objective of this study was to determine the significance of exercise‐related PVCs for predicting occurrence of ventricular fibrillation (VF) in patients with Brugada syndrome.
Methods and Results
The subjects were 307 patients with Brugada syndrome who performed a treadmill exercise test. We evaluated the occurrence of PVCs at rest, during exercise and at the peak of exercise, and during recovery after exercise (0–5 minutes). We followed the patients for 92±68 months and evaluated the occurrence of VF. PVCs occurred in 82 patients (27%) at the time of treadmill exercise test: PVCs appeared at rest in 14 patients (4%), during exercise in 60 patients (20%), immediately after exercise (0–1.5 minutes) in 28 patients (9%), early after exercise (1.5–3 minutes) in 18 patients (6%), and late after exercise (3–5 minutes) in 12 patients (4%). Thirty patients experienced VF during follow‐up. Multivariable analysis including symptoms, spontaneous type 1 ECG, and PVCs in the early recovery phase showed that these factors were independently associated with VF events during follow‐up.
Conclusions
PVCs early after an exercise test are associated with future occurrence of VF events. Rebound of vagal nerve activity at the early recovery phase would promote ST‐segment augmentation and PVCs in high‐risk patients with Brugada syndrome. en-copyright= kn-copyright= en-aut-name=MoritaHiroshi en-aut-sei=Morita en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AsadaSaori T. en-aut-sei=Asada en-aut-mei=Saori T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyamotoMasakazu en-aut-sei=Miyamoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MorimotoYoshimasa en-aut-sei=Morimoto en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimuraTomonari en-aut-sei=Kimura en-aut-mei=Tomonari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MizunoTomofumi en-aut-sei=Mizuno en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakagawaKoji en-aut-sei=Nakagawa en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeAtsuyuki en-aut-sei=Watanabe en-aut-mei=Atsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NishiiNobuhiro en-aut-sei=Nishii en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= affil-num=1 en-affil=Department of Cardiovascular Therapeutics, 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 and Dentistry kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=9 en-affil=Department of Cardiovascular Therapeutics, 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 and Dentistry kn-affil= en-keyword=Brugada syndrome kn-keyword=Brugada syndrome en-keyword=exercise test kn-keyword=exercise test en-keyword=premature ventricular contractions kn-keyword=premature ventricular contractions en-keyword=sudden death kn-keyword=sudden death en-keyword=ventricular fibrillation kn-keyword=ventricular fibrillation END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=22 article-no= start-page=e14640 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201123 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Alteration of chemokine production in bovine endometrial epithelial and stromal cells under heat stress conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=After parturition, cows frequently develop uterine bacterial infections, resulting in the onset of endometritis. To eliminate the bacteria, bovine endometrial cells secrete chemokines, such as IL-6 and MCP1, which attract macrophages (M Phi s) to the subepithelial stroma. These attracted M Phi s are not only involved in bacterial elimination but also the orchestration of inflammation and tissue repair. These immune responses aid in the recovery from endometritis; however, the recovery from endometritis takes longer in summer than in any other season. Based on these findings, we hypothesized that heat stress (HS) affects the chemokine production in endometrial cells. To confirm this hypothesis, we compared IL-6 and MCP1 production induced by lipopolysaccharide (LPS) in bovine endometrial epithelial and stromal cells under normal (38.5 degrees C) and HS conditions (40.5 degrees C). In the endometrial epithelial cells, IL-6 production stimulated by LPS was significantly (p < .05) suppressed under HS conditions. MCP1 production in endometrial epithelial cells was not detected under both the control and HS conditions regardless of the presence of LPS. Moreover, LPS significantly (p < .05) stimulated IL-6 and MCP1 production in endometrial stromal cells. Moreover, HS significantly (p < .05) enhanced their production compared to that under the control conditions. In addition, HS did not affect the migration ability of M Phi s; however, the supernatant of the endometrial stromal cells cultured under the HS condition significantly (p < .05) attracted the M Phi s when compared to the control condition. These results suggest that HS disrupts chemokine production in two types of endometrial cells and alters the distribution of M Phi s in the endometrium during the summer. en-copyright= kn-copyright= en-aut-name=SakaiShunsuke en-aut-sei=Sakai en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=YamamotoYuki en-aut-sei=Yamamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KimuraKoji en-aut-sei=Kimura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Laboratory of Reproductive 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 Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=chemokine kn-keyword=chemokine en-keyword=cow kn-keyword=cow en-keyword=endometrial cells kn-keyword=endometrial cells en-keyword=endometritis kn-keyword=endometritis en-keyword=heat stress kn-keyword=heat stress END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue= article-no= start-page=4298 end-page=4317 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201207 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Multi‐scale inter‐temporal capital asset pricing model en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study investigates the multi‐scale inter‐temporal capital asset pricing model (ICAPM). We focus upon differences across timescales since they represent heterogeneities of investors in markets. This study employs a wavelet approach to decompose return data into multiple timescales. Furthermore, we impose a same risk‐aversion parameter constraint into all portfolios, which is proposed by Engle and Bali who show that the constraint provides a reasonable equity risk premium at a daily frequency. We observe positive relations between the expected returns on portfolios and the covariance of the market at a daily frequency, while these relations change as timescales increase. We find that a negative risk–return relation, which might be related to a correction process of overreaction at an approximately weekly frequency (2–16 days). The strongest positive relation is observed at an approximately monthly frequency (16–32 days). Monthly portfolio re‐balances are widely used and might impact stock market return patterns. The equity risk premium in the longer frequency ranges from 8.64 to 11.10%. Our results are robust after controlling for macroeconomic variables, market implied volatility and test portfolios. Moreover, we investigate size and value factors and reveal that the risk premia disappear in the longer frequency, which suggests that ICAPM is satisfied. en-copyright= kn-copyright= en-aut-name=SakemotoRyuta en-aut-sei=Sakemoto en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil= en-keyword=ICAPM kn-keyword=ICAPM en-keyword=investment horizon kn-keyword=investment horizon en-keyword=risk factor kn-keyword=risk factor en-keyword=risk‐aversion kn-keyword=risk‐aversion en-keyword=wavelet kn-keyword=wavelet END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=1 article-no= start-page=180 end-page=184 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201106 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Surgical resection of a giant peripheral ossifying fibroma in mouth floor managed with fiberscopic intubation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tracheal intubation for general anesthesia can sometimes be difficult in patients with a large mass in the mouth floor.

Ischemia reperfusion injury contributes to mortality and morbidity in many pathological conditions in emergency medicine clinical practice, including trauma, ischemic stroke, myocardial infarction, and post-cardiac arrest syndrome. The process of IR is multifactorial, and its pathogenesis involves several mechanisms. Reactive oxygen species are considered key molecules in reperfusion injury due to their potent oxidizing and reducing effects that directly damage cellular membranes by lipid peroxidation. In general, IR injury to an individual organ causes various pro-inflammatory mediators to be released, which could then induce inflammation in remote organs, thereby possibly advancing the dysfunction of multiple organs. In this review, we summarize IR injury in emergency medicine. Potential therapies include pharmacological treatment, ischemic preconditioning, and the use of medical gases or vitamin therapy, which could significantly help experts develop strategies to inhibit IR injury. en-copyright= kn-copyright= en-aut-name=NaitouHiromichi en-aut-sei=Naitou en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=FujisakiNoritomo en-aut-sei=Fujisaki en-aut-mei=Noritomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoHirotsugu en-aut-sei=Yamamoto en-aut-mei=Hirotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamadaTaihei en-aut-sei=Yamada en-aut-mei=Taihei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=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= en-aut-name=OsakoTakaaki en-aut-sei=Osako en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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= 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, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Emergency medicine kn-keyword=Emergency medicine en-keyword=inflammation kn-keyword=inflammation en-keyword=ischemia reperfusion kn-keyword=ischemia reperfusion en-keyword=remote ischemic preconditioning kn-keyword=remote ischemic preconditioning en-keyword=shock kn-keyword=shock en-keyword=therapeutic hypothermia kn-keyword=therapeutic hypothermia END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=16 article-no= start-page=e015103 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200818 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Luseogliflozin on Heart Failure With Preserved Ejection Fraction in Patients With Diabetes Mellitus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Effects of sodium‐glucose cotransporter 2 inhibitors on reducing hospitalization for heart failure have been reported in randomized controlled trials, but their effects on patients with heart failure with preserved ejection fraction (HFpEF) are unknown. This study aimed to evaluate the drug efficacy of luseogliflozin, a sodium‐glucose cotransporter 2 inhibitor, in patients with type 2 diabetes mellitus and HFpEF.
Methods and Results
We performed a multicenter, open‐label, randomized, controlled trial for comparing luseogliflozin 2.5 mg once daily with voglibose 0.2 mg 3 times daily in patients with type 2 diabetes mellitus suffering from HFpEF (left ventricular ejection fraction >45% and BNP [B‐type natriuretic peptide] concentrations ≥35 pg/mL) in a 1:1 randomization fashion. The primary outcome was the difference from baseline in BNP levels after 12 weeks of treatment between the 2 drugs. A total of 173 patients with diabetes mellitus and HFpEF were included. Of these, 83 patients were assigned to receive luseogliflozin and 82 to receive voglibose. There was no significant difference in the reduction in BNP concentrations after 12 weeks from baseline between the 2 groups. The ratio of the mean BNP value at week 12 to the baseline value was 0.79 in the luseogliflozin group and 0.87 in the voglibose group (percent change, −9.0% versus −1.9%; ratio of change with luseogliflozin versus voglibose, 0.93; 95% CI, 0.78–1.10; P=0.26).
Conclusion
In patients with type 2 diabetes mellitus and HFpEF, there is no significant difference in the degree of reduction in BNP concentrations after 12 weeks between luseogliflozin and voglibose.

kn-subtitle= en-abstract= kn-abstract=Ticks are blood‐feeding ectoparasites that transmit a variety of pathogens to host animals and humans, causing severe infectious diseases such as Lyme disease. In a certain combination of animal and tick species, tick infestation elicits acquired immunity against ticks in the host, which can reduce the ability of ticks to feed on blood and to transmit pathogens in the following tick infestations. Therefore, our understanding of the cellular and molecular mechanisms of acquired tick resistance (ATR) can advance the development of anti‐tick vaccines to prevent tick infestation and tick‐borne diseases. Basophils are a minor population of white blood cells circulating in the bloodstream and are rarely observed in peripheral tissues under steady‐state conditions. Basophils have been reported to accumulate at tick‐feeding sites during re‐infestation in cattle, rabbits, guinea pigs and mice. Selective ablation of basophils resulted in a loss of ATR in guinea pigs and mice, illuminating the essential role of basophils in the manifestation of ATR. In this review, we discuss the recent advance in the elucidation of the cellular and molecular mechanisms underlying basophil recruitment to the tick‐feeding site and basophil‐mediated ATR. en-copyright= kn-copyright= en-aut-name=YoshikawaSoichiro en-aut-sei=Yoshikawa en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyakeKensuke en-aut-sei=Miyake en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KamiyaAtsunori en-aut-sei=Kamiya en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KarasuyamaHajime en-aut-sei=Karasuyama en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Inflammation, Infection and Immunity Laboratory, TMDU Advanced Research Institute, Tokyo Medical and Dental University (TMDU) kn-affil= affil-num=3 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Inflammation, Infection and Immunity Laboratory, TMDU Advanced Research Institute, Tokyo Medical and Dental University (TMDU) kn-affil= en-keyword=acquired immunity kn-keyword=acquired immunity en-keyword=basophil kn-keyword=basophil en-keyword=histamine kn-keyword=histamine en-keyword=IgE kn-keyword=IgE en-keyword=IL‐3 kn-keyword=IL‐3 en-keyword=mast cell kn-keyword=mast cell en-keyword=Tick kn-keyword=Tick END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=S1 article-no= start-page=67 end-page=68 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201904 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Current problems and clinical results of endoscopic necrosectomy for walled‐off pancreatic necrosis en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki 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=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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= END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=3 article-no= start-page=425 end-page=430 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy and safety of scheduled early endoscopic ultrasonography‐guided ethanol reinjection for patients with pancreatic neuroendocrine tumors: Prospective pilot study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Endoscopic ultrasonography (EUS)‐guided ethanol injection was recently proposed for treatment of patients with small pancreatic neuroendocrine tumors (p‐NET); however, tips on how to carry out safe and effective procedures are unclear. We launched a pilot study for scheduled early EUS‐guided ethanol reinjection for small p‐NET. Major eligibility criteria were presence of pathologically diagnosed grade (G) 1 or G2, tumor size ≤2 cm and being a poor or rejected candidate for surgery. For the treatment, we used a 25‐gauge needle and pure ethanol. Contrast‐enhanced computed tomography (CE‐CT) was carried out on postoperative day 3, and if enhanced areas of the tumor were still apparent, an additional session was scheduled during the same hospitalization period. Primary endpoint was complete ablation rate at 1 month after treatment, and secondary endpoint was procedure‐related adverse events. A total of five patients were treated. Median size of the tumor was 10 (range: 7–14) mm. Of the five patients, three underwent an additional session. Median volume of ethanol injection per session was 0.8 (range: 0.3–1.0) mL, and the total was 1.0 (0.9–1.8) mL. Complete ablation was achieved in four of the five tumors (80%) with no adverse events. During 1 year of follow up, none of the patients reported any procedure‐related adverse events, and no recurrence of tumor. Scheduled early EUS‐guided ethanol reinjection appears to be safe and effective for treating small p‐NET (UMIN number: 000018834). en-copyright= kn-copyright= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki 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=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiwaraHiroyasu en-aut-sei=Fujiwara en-aut-mei=Hiroyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishidaKenji en-aut-sei=Nishida en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HaradaRyo en-aut-sei=Harada en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=Fujii Masakuni en-aut-sei=Fujii en-aut-mei=Masakuni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 ORCID= en-aut-name=HinotsuShiro en-aut-sei=Hinotsu en-aut-mei=Shiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=Yagi Takahito en-aut-sei=Yagi en-aut-mei=Takahito 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 Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology, Japanese Red Cross Okayama Hospital kn-affil= affil-num=7 en-affil=Department of Internal Medicine, Okayama Saiseikai General Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Transplant and Surgical Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Transplant and Surgical Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Gastroenterological Surgery, Transplant and Surgical Oncology, 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=ethanol injection kn-keyword=ethanol injection en-keyword=EUS‐guided therapy kn-keyword=EUS‐guided therapy en-keyword=pancreatic neuroendocrine tumor kn-keyword=pancreatic neuroendocrine tumor en-keyword=scheduled therapy kn-keyword=scheduled therapy en-keyword=small size kn-keyword=small size END start-ver=1.4 cd-journal=joma no-vol=2021 cd-vols= no-issue=14 article-no= start-page=640 end-page=643 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201027 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Intracorporeal semi‐hand‐sewn Billroth I reconstruction in total laparoscopic distal gastrectomy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction
Intracorporeal Billroth I (B‐I) reconstruction using an endoscopic linear stapler (ELS) is widely performed in total laparoscopic distal gastrectomy. However, conventional procedures require many ELSs for anastomosis. Here, we introduce the novel intracorporeal semi‐hand‐sewn (SHS) B‐I reconstruction.
Materials and surgical technique
After the transection of stomach and duodenum using ELS following adequate lymph node dissection, small entry holes were made on the anterior wall in the greater curvature of the stomach and the duodenal stump. The posterior walls of both the remnant stomach and the duodenum were attached with the ELS and fired to create the posterior wall of the B‐I anastomosis. All the transection line of the duodenum and one‐third of the transection line of the stomach were dissected; finally the anterior wall suturing at the anastomotic site was performed by the laparoscopic hand‐sewn technique.
Discussion
SHS procedure was performed for 17 gastric cancer patients. There were no intraoperative complications or conversions to open surgery. One intra‐abdominal abscess was observed although there was no anastomotic leakage. The median reconstruction time was 48 minutes (32‐63). The SHS procedure was safe, feasible, and economical, although it requires sufficient laparoscopic suturing and ligation skill. 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=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=NishizakiMasahiko en-aut-sei=Nishizaki en-aut-mei=Masahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=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=Kakiuchi Yoshihiko en-aut-sei=Kakiuchi en-aut-mei= Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YanoShuya en-aut-sei=Yano en-aut-mei=Shuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=Noma Kazuhiro 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=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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= en-keyword=Billroth I reconstruction kn-keyword=Billroth I reconstruction en-keyword=gastric cancer kn-keyword=gastric cancer en-keyword=laparoscopic distal gastrectomy kn-keyword=laparoscopic distal gastrectomy END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=1 article-no= start-page=219 end-page=232 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200904 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pathogenetic roles of beet necrotic yellow vein virus RNA5 in the exacerbation of symptoms and yield reduction, development of scab‐like symptoms, and Rz1‐resistance breaking in sugar beet en-subtitle= kn-subtitle= en-abstract= kn-abstract=Beet necrotic yellow vein virus (BNYVV) generally has a four‐segmented positive‐sense RNA genome (RNAs 1–4), but some European and most Asian strains have an additional segment, RNA5. This study examined the effect of RNA5 and RNA3 on different sugar beet cultivars using a Polymyxa‐mediated inoculation system under field and laboratory conditions. In field tests, the degree of sugar yield served as an index for assessing the virulence of BNYVV strains. Japanese A‐II type isolates without RNA5 caused mostly 15%–90% sugar yield reductions, depending on the susceptibility of sugar beet cultivars, whereas the isolates with RNA5 induced more than 90% yield losses in the seven susceptible cultivars, but small yield losses in one Rz1‐resistant and Rizor cultivars. However, a laboratory‐produced isolate containing RNA5 but lacking RNA3 caused higher yield losses in Rizor than in susceptible plants, and induced scab‐like symptoms on the root surface of both susceptible and resistant plants. In laboratory tests, A‐II type isolates without RNA5 had low viral RNA accumulation levels in roots of Rizor and Rz1‐resistant plants at early stages of infection, but in the presence of RNA5, viral RNA3 accumulation levels increased remarkably. This increased RNA3 accumulation was not observed in roots of the WB42 accession with the Rz2 gene. In contrast, the presence of RNA3 did not affect RNA5 accumulation levels. Collectively, this study demonstrated that RNA5 is involved in the development of scab‐like symptoms and the enhancement of RNA3 accumulation, and suggests these characteristics of RNA5 are associated with Rz1‐resistance breaking. en-copyright= kn-copyright= en-aut-name=TamadaTetsuo en-aut-sei=Tamada en-aut-mei=Tetsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UchinoHirokatsu en-aut-sei=Uchino en-aut-mei=Hirokatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KusumeToshimi en-aut-sei=Kusume en-aut-mei=Toshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Iketani‐SaitoMinako en-aut-sei=Iketani‐Saito en-aut-mei=Minako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ChibaSotaro en-aut-sei=Chiba en-aut-mei=Sotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AndikaIda Bagus en-aut-sei=Andika en-aut-mei=Ida Bagus kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=2 en-affil=Research Center, Nippon Beet Sugar Mfg.

Dynamin 1 is also expressed in the kidney; however, its physiological significance to this organ remains unknown. Here, we show that dynamin 1 is crucial for microtubule organization and stabilization in glomerular podocytes. By immunofluorescence and immunoelectron microscopy, dynamin 1 was concentrated at microtubules at primary processes in rat podocytes. By immunofluorescence of differentiated mouse podocytes (MPCs), dynamin 1 was often colocalized with microtubule bundles, which radially arranged toward periphery of expanded podocyte. In dynamin 1-depleted MPCs by RNAi, alpha-tubulin showed a dispersed linear filament-like localization, and microtubule bundles were rarely observed. Furthermore, dynamin 1 depletion resulted in the formation of discontinuous, short acetylated alpha-tubulin fragments, and the decrease of microtubule-rich protrusions. Dynamins 1 and 2 double-knockout podocytes showed dispersed acetylated alpha-tubulin and rare protrusions. In vitro, dynamin 1 polymerized around microtubules and cross-linked them into bundles, and increased their resistance to the disassembly-inducing reagents Ca(2+)and podophyllotoxin. In addition, overexpression and depletion of dynamin 1 in MPCs increased and decreased the nocodazole resistance of microtubules, respectively. These results suggest that dynamin 1 supports the microtubule bundle formation and participates in the stabilization of microtubules. en-copyright= kn-copyright= en-aut-name=LaThe Mon en-aut-sei=La

Screening Questionnaire for Individuals with Intellectual Disabilities en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background,
Dementia in people with intellectual disabilities (IDs) is difficult to detect because of preexisting cognitive deficits. An effective screening method is required. The Dementia Screening Questionnaire for Individuals with Intellectual Disabilities (DSQIID) was developed as an observer rating tool to screen dementia in people with ID. The aim of this study was to verify the screening accuracy of the DSQIID for Japanese people with ID.
Methods
Four‐hundred ninety‐three subjects with ID participated in this study. Caregivers who had observed the participants for more than 2 years scored the Japanese version of the DSQIID (DSQIID‐J) of the participants. Three doctors examined participants directly and diagnosed dementia using the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria. To identify the key screening items that predict dementia, the specificities of a single and pairs of items with 100% sensitivity were evaluated relative to the dementia diagnosis.
Results
Of 493 participants, 34 were people with Down syndrome (DS), and 459 were people without DS. Seventeen participants were diagnosed with dementia. The suitable cut‐off score of the DSQIID‐J was 10/11 (sensitivity 100% and specificity 96.8%) for screening dementia. The inter‐rater reliability, test–retest reliability and internal consistency of the DSQIID‐J were excellent. Regarding key items, there was no single item with 100% sensitivity, and the best two‐item combination was the pair of ‘Cannot dress without help’ and ‘Walks slower’ (sensitivity 100% and specificity 93.5%).
Conclusions
We identified several important question items of the DSQIID‐J related to the diagnosis of dementia in people with ID. The DSQIID‐J is a useful screening tool for dementia in adults with ID. en-copyright= kn-copyright= en-aut-name=TakenoshitaShintaro en-aut-sei=Takenoshita en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TeradaS. en-aut-sei=Terada en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KuwanoR. en-aut-sei=Kuwano en-aut-mei=R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueT. en-aut-sei=Inoue en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KurozumiT. en-aut-sei=Kurozumi en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ChojuA. en-aut-sei=Choju en-aut-mei=A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuemitsuS. en-aut-sei=Suemitsu en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamadaNorihito en-aut-sei=Yamada en-aut-mei=Norihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Asahigawaso Research Institute, Asahigawaso Medical Welfare Center kn-affil= affil-num=4 en-affil=Asahigawaso Research Institute, Asahigawaso Medical Welfare Center kn-affil= affil-num=5 en-affil=Asahigawaso Research Institute, Asahigawaso Medical Welfare Center kn-affil= affil-num=6 en-affil=Asahigawaso Research Institute, Asahigawaso Medical Welfare Center kn-affil= affil-num=7 en-affil=Asahigawaso Research Institute, Asahigawaso Medical Welfare Center kn-affil= affil-num=8 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=cognitive impairment kn-keyword=cognitive impairment en-keyword=dementia kn-keyword=dementia en-keyword=Down syndrome kn-keyword=Down syndrome en-keyword=DSQIID kn-keyword=DSQIID en-keyword=intellectual disabilities kn-keyword=intellectual disabilities en-keyword=screening tool kn-keyword=screening tool END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue= article-no= start-page=656 end-page=662 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200902 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy of low dose rectal diclofenac for preventing post‐endoscopic retrograde cholangiopancreatography pancreatitis: Propensity score‐matched analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Acute pancreatitis is a major adverse event of endoscopic retrograde cholangiopancreatography (ERCP). Rectal administration of non‐steroidal anti‐inflammatory drugs (NSAIDs) decreases the incidence of post‐ERCP pancreatitis (PEP). However, the efficacy of low dose rectal NSAIDs for preventing PEP remains controversial.
Methods
We performed a retrospective study of 301 patients with native papilla and a body weight of <50 kg who underwent ERCP between September 2010 and October 2019. After July 2016, a 25 mg dose of rectal diclofenac was routinely administered within 15 min before ERCP (NSAIDs group, n = 72) and the control group (n = 229) consisted of patients undergoing ERCP before this date without treatment. We compared the incidence of PEP between the two groups using propensity score matching.
Results
A total of 66 pairs of patients in each group were selected. The patients and procedural‐related factors were similar in both groups. In total, 15 patients (11.4%) developed PEP: 12.1% (8/66) in the NSAIDs group and 10.6% (7/66) in the control group (Odds ratio (OR) 1.2; 95% confidence interval (CI) 0.4–3.5; P = 0.78). There was no significant difference in incidence of other adverse events related to ERCP between the two groups.
Conclusions
Prophylactic administration of a 25 mg dose of rectal diclofenac did not reduce the incidence of PEP in patients with a native papilla and a body weight of <50 kg in this study and a certain dose of rectal NSAIDs, such as a 100‐mg dose, should be administered regardless of body weight to prevent PEP. en-copyright= kn-copyright= en-aut-name=TomodaTakeshi en-aut-sei=Tomoda en-aut-mei=Takeshi 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=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=UetaEijiro en-aut-sei=Ueta en-aut-mei=Eijiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiiYuuki en-aut-sei=Fujii en-aut-mei=Yuuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaragaiYousuke en-aut-sei=Saragai en-aut-mei=Yousuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 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=10 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=11 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=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=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= en-keyword=diclofenac kn-keyword=diclofenac en-keyword=low dose kn-keyword=low dose en-keyword=post‐ERCP pancreatitis kn-keyword=post‐ERCP pancreatitis END start-ver=1.4 cd-journal=joma no-vol=59 cd-vols= no-issue=20 article-no= start-page=7803 end-page=7807 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electrochemical Synthesis of Thienoacene Derivatives: Transition‐Metal‐Free Dehydrogenative C−S Coupling Promoted by a Halogen Mediator en-subtitle= kn-subtitle= en-abstract= kn-abstract=The first electrochemical dehydrogenative C−S bond formation leading to thienoacene derivatives is described.

Whereas magnocellular AVP neurons project primarily to the posterior pituitary, parvocellular AVP neurons project to the median eminence (ME) and to extrahypothalamic areas. The AVP gene encodes pre‐pro‐AVP that comprises the signal peptide, AVP, neurophysin (NPII), and a copeptin glycopeptide. In the present study, we used an N‐terminal copeptin antiserum to examine copeptin expression in magnocellular and parvocellular neurons in the hypothalamus in the mouse, rat, and macaque monkey. Although magnocellular NPII‐expressing neurons exhibited strong N‐terminal copeptin immunoreactivity in all three species, a great majority (~90%) of parvocellular neurons that expressed NPII was devoid of copeptin immunoreactivity in the mouse, and in approximately half (~53%) of them in the rat, whereas in monkey hypothalamus, virtually all NPII‐immunoreactive parvocellular neurons contained strong copeptin immunoreactivity. Immunoelectron microscopy in the mouse clearly showed copeptin‐immunoreactivity co‐localized with NPII‐immunoreactivity in neurosecretory vesicles in the internal layer of the ME and posterior pituitary, but not in the external layer of the ME. Intracerebroventricular administration of a prohormone convertase inhibitor, hexa‐d‐arginine amide resulted in a marked reduction of copeptin‐immunoreactivity in the NPII‐immunoreactive magnocellular PVN neurons in the mouse, suggesting that low protease activity and incomplete processing of pro‐AVP could explain the disproportionally low levels of N‐terminal copeptin expression in rodent AVP (NPII)‐expressing parvocellular neurons. Physiologic and phylogenetic aspects of copeptin expression among neuroendocrine neurons require further exploration. en-copyright= kn-copyright= en-aut-name=KawakamiNatsuko en-aut-sei=Kawakami en-aut-mei=Natsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtuboAkito en-aut-sei=Otubo en-aut-mei=Akito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaejimaSho en-aut-sei=Maejima en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TalukderAshraf H. en-aut-sei=Talukder en-aut-mei=Ashraf H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SatohKeita en-aut-sei=Satoh en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtiTakumi en-aut-sei=Oti en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakanamiKeiko en-aut-sei=Takanami en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UedaYasumasa en-aut-sei=Ueda en-aut-mei=Yasumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ItoiKeiichi en-aut-sei=Itoi en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MorrisJohn F. en-aut-sei=Morris en-aut-mei=John F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SakamotoTatsuya en-aut-sei=Sakamoto en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=SakamotoHirotaka en-aut-sei=Sakamoto en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Laboratory of Information Biology, Graduate School of Information Sciences, Tohoku University kn-affil= affil-num=5 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Department of Physiology, Kyoto Prefectural University of Medicine kn-affil= affil-num=9 en-affil=Laboratory of Information Biology, Graduate School of Information Sciences, Tohoku University kn-affil= affil-num=10 en-affil=Department of Physiology, Anatomy and Genetics, University of Oxford kn-affil= affil-num=11 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=12 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=copeptin kn-keyword=copeptin en-keyword=hypothalamo‐pituitary–adrenal system kn-keyword=hypothalamo‐pituitary–adrenal system en-keyword=immunohistochemistry kn-keyword=immunohistochemistry en-keyword=paraventricular nucleus of the hypothalamus kn-keyword=paraventricular nucleus of the hypothalamus en-keyword=processing kn-keyword=processing en-keyword=vasopressin kn-keyword=vasopressin en-keyword=RRID: AB_2722604 kn-keyword=RRID: AB_2722604 en-keyword=RRID: AB_2061966 kn-keyword=RRID: AB_2061966 en-keyword=RRID: AB_2314234 kn-keyword=RRID: AB_2314234 en-keyword=RRID: AB_10013361 kn-keyword=RRID: AB_10013361 en-keyword=RRID: AB_2313960 kn-keyword=RRID: AB_2313960 en-keyword=RRID: AB_2722605 kn-keyword=RRID: AB_2722605 en-keyword=RRID: AB_90782 kn-keyword=RRID: AB_90782 END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=12 article-no= start-page=3619 end-page=3620 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200920 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Intra-arterial gas, a clue for diagnosis of peri-aortic inflammation due to infection en-subtitle= kn-subtitle= en-abstract= kn-abstract=We have presented a case of Salmonella-induced infective aortic aneurysm in which the presence of peri-aortic gas was a clue for diagnosis.

Human telomerase reverse transcriptase (TERT) promoter mutations were the most prevalent mutations in patients with hepatocellular carcinoma (HCC). We tried to detect the mutations with plasma circulating tumor DNA (ctDNA) in patients with advanced HCC and elucidated their clinical utility.
Methods
Circulating tumor DNA in plasma was extracted from 130 patients with advanced HCC who were treated with systemic chemotherapy (n = 86) or transcatheter arterial chemoembolization (n = 44), and TERT promoter mutations were examined with digital droplet polymerase chain reaction. The correlations between these mutations and the clinical outcome of patients were analyzed.
Results
Of the 130 patients examined, 71 patients (54.6%) were positive for TERT promoter mutations in ctDNA, of which 64 patients were −124bp G > A and 10 were −146bp G > A. The presence of TERT promoter mutations was correlated with large intrahepatic tumor size (P = 0.05) and high des‐gamma carboxyprothrombin (P = 0.005). Overall survival of the patients with the mutations was significantly shorter than those without them (P < 0.001), and the patients with high (≥ 1%) fractional abundance of the mutant alleles showed shorter survival than those with low (< 1%) fractional abundance. Multivariate analysis revealed that TERT promoter mutation (hazard ratio [HR]: 1.94; 95% confidence interval [CI], 1.18–3.24; P < 0.01), systemic chemotherapy (HR: 2.38; 95% CI, 1.29–4.57; P < 0.01), and vascular invasion (HR: 2.16; 95% CI, 1.22–3.76; P < 0.01) were significant factors for poor overall survival.
Conclusions
TERT promoter mutations in ctDNA were associated with short survival and could be a valuable biomarker for predicting the prognosis of patients with advanced HCC. en-copyright= kn-copyright=

of Pressure‐Induced Amorphization of Fe2SiO4 Fayalite en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fayalite (Fe2SiO4), which is an end member of the olivine series ((FexMg1 − x)2SiO4), undergoes a crystal‐to‐amorphous transformation under high pressure at room temperature conditions. This pressure‐induced amorphized fayalite has an interesting feature: it exhibits antiferromagnetism at low temperature regardless of its non‐crystalline structure. In spite of this unique property, the first‐principles investigation of pressure‐induced amorphized fayalite has not been carried out yet. Herein, to clarify the energetic and structural properties of pressure‐induced amorphized fayalite, the first‐principles molecular dynamics simulations of the compression and decompression processes of fayalite in the pressure range 0–120 GPa are performed. The energetic and structural properties are also compared with those of well‐equilibrated melt‐quenched amorphous Fe2SiO4. Based on structural analysis, it is confirmed that not only sixfold but also fivefold coordinated silicon atoms exist in the amorphous‐like structure under high pressure. In addition, it is found that the silicon atoms play the role of network former in the amorphous‐like phase under high pressure, but change to a network‐modifier role after release to ambient conditions. Moreover, it is found that the obtained amorphous‐like phase has a partially ordered structure. It is inferred that the partially ordered structure likely enables the pressure‐amorphized fayalite to exhibit antiferromagnetism. en-copyright= kn-copyright= en-aut-name=MisawaMasaaki en-aut-sei=Misawa en-aut-mei=Masaaki kn-aut-name=三澤賢明 kn-aut-sei=三澤 kn-aut-mei=賢明 aut-affil-num=1 ORCID= en-aut-name=ShimojoFuyuki en-aut-sei=Shimojo en-aut-mei=Fuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Physics, Kumamoto University kn-affil= en-keyword=amorphous structures kn-keyword=amorphous structures en-keyword=density functional theory kn-keyword=density functional theory en-keyword=iron silicate kn-keyword=iron silicate en-keyword=molecular dynamics kn-keyword=molecular dynamics END start-ver=1.4 cd-journal=joma no-vol=85 cd-vols= no-issue=9 article-no= start-page=2737 end-page=2744 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200825 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A comparative study of the antioxidant profiles of olive fruit and leaf extracts against five reactive oxygen species as measured with a multiple free‐radical scavenging method en-subtitle= kn-subtitle= en-abstract= kn-abstract=Olive fruits and leaves are recognized to have great potential as natural sources of antioxidants. The major phenolic antioxidant component in these plant tissues is oleuropein. The antioxidant activity of olive fruits and leaves was evaluated in this study using multiple free‐radical scavenging (MULTIS) methods, wherein we determined the scavenging abilities of different extracts against five reactive oxygen species (ROS; HO·, O2−·, RO·, t‐BuOO·, and 1O2). Raw olive fruits taste bitter and are inedible without undergoing a debittering treatment. Following the NaOH‐debittering process, the radical scavenging activity of olives decreased by 90%. The MULTIS measurements indicated that oleuropein and hydroxytyrosol are responsible for the radical scavenging activity of olive fruits. Furthermore, we evaluated the radical scavenging profiles of olive leaf extracts against five ROS and found significant seasonal variations in their antioxidant activities. Leaves picked in August possessed greater radical scavenging abilities (180% to 410% for different ROS) than those picked in the cold season (December and February). In roasted olive leaves, we found marked increases (230% to 300% and 180% to 220%) in the antioxidant activities of Maillard reaction products against RO· and t‐BuOO·, respectively. This study presented a useful comparative analysis of the antioxidant capacities of food against various types of ROS. en-copyright= kn-copyright= en-aut-name=SueishiYoshimi en-aut-sei=Sueishi en-aut-mei=Yoshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NiiRisako en-aut-sei=Nii en-aut-mei=Risako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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= en-keyword=antioxidant capacity kn-keyword=antioxidant capacity en-keyword=fruit extract kn-keyword=fruit extract en-keyword=leaf extract kn-keyword=leaf extract en-keyword=MULTIS kn-keyword=MULTIS en-keyword=olive kn-keyword=olive END start-ver=1.4 cd-journal=joma no-vol=99 cd-vols= no-issue=1 article-no= start-page=410 end-page=420 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200712 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Suspension pattern and rising height of sedimentary particles with low concentration in a mechanically stirred vessel en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, the effects of impeller rotation speed, off‐bottom clearance, blade angle, types of solid and liquid, etc., on the suspension pattern of sedimentary particles and particle rise height in liquid were investigated with a hemispherical vessel without baffles under low particle concentration. The transition conditions of suspension pattern between regimes I and II, and regimes II and III, were observed visually, and their non‐dimensional equations were expressed with an acceptable correlation by varying the above operation factors a great deal. Here, regime I is stagnation of particles on a vessel bottom, II is partial suspension, and III is complete suspension in liquid. The non‐dimensional equation of the maximum particle rise height was also successfully obtained. The combination of the non‐dimensional equations of transition and maximum particle rise height permitted us to determine the adequate solid/liquid mixing operation conditions without collision of particles with device parts. en-copyright= kn-copyright= en-aut-name=TokuraYuichiro en-aut-sei=Tokura en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyagawaKeita en-aut-sei=Miyagawa en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UddinMd.

Thus, the efficacy of immune checkpoint inhibitors (ICIs) in patients with poor PS remains unclear. Herein, we used data from a retrospective cohort to assess the potential clinical benefits of ICIs in NSCLC patients with poor PS. Data from NSCLC patients who received ICI monotherapy at 9 institutions between December 2015 and May 2018 were retrospectively analyzed. After excluding 4 patients who lacked PS data, a total of 527 ICI-treated patients, including 79 patients with PS 2 or higher, were used for our analyses. The progression-free survival (PFS) and overall survival (OS) of patients with PS 2 or higher were significantly shorter compared with those of PS 0-1 patients (median PFS, 4.1 vs 2.0 months;P < .001 and median OS, 17.4 vs 4.0 months;P < .001). Among NSCLC patients with programmed cell death protein-ligand 1 (PD-L1) expression of 50% or higher who were treated with pembrolizumab as first-line therapy, the median PFS times of patients with PS 2 and 0-1 were 7.3 and 8.1 months, respectively. There was no significant difference in PFS between patients with PS 2 and 0-1 (P = .321). Although poor PS was significantly associated with worse outcomes in NSCLC patients treated with ICIs, pembrolizumab as a first-line treatment in NSCLC patients expressing high levels of PD-L1 could provide a clinical benefit, even in patients with PS 2. en-copyright= kn-copyright= en-aut-name=KanoHirohisa en-aut-sei=Kano en-aut-mei=Hirohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=HaradaDaijiro en-aut-sei=Harada en-aut-mei=Daijiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueKoji en-aut-sei=Inoue en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KayataniHiroe en-aut-sei=Kayatani en-aut-mei=Hiroe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HosokawaShinobu en-aut-sei=Hosokawa en-aut-mei=Shinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KishinoDaizo en-aut-sei=Kishino en-aut-mei=Daizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeKazuhiko en-aut-sei=Watanabe en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OchiNobuaki en-aut-sei=Ochi en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OdaNaohiro en-aut-sei=Oda en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HaraNaofumi en-aut-sei=Hara en-aut-mei=Naofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 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=13 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=14 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=15 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 Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Thoracic Oncology, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=4 en-affil=Department of Respiratory Medicine, Ehime Prefectural Central Hospital kn-affil= affil-num=5 en-affil=Department of Respiratory Medicine, National Hospital Organization Okayama Medical Center kn-affil= affil-num=6 en-affil=Department of Respiratory Medicine, Japanese Red Cross Okayama Hospital kn-affil= affil-num=7 en-affil=Department of Respiratory Medicine, Himeji Red Cross Hospital kn-affil= affil-num=8 en-affil=Department of Internal Medicine, Okayama Saiseikai General Hospital kn-affil= affil-num=9 en-affil=Department of General Internal Medicine 4, Kawasaki Medical School kn-affil= affil-num=10 en-affil=Department of Internal Medicine, Fukuyama City Hospital kn-affil= affil-num=11 en-affil=Department of Hematology, Oncology, and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Hematology, Oncology, and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=14 en-affil=Department of Hematology, Oncology, and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=15 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= en-keyword=immune checkpoint inhibitor kn-keyword=immune checkpoint inhibitor en-keyword=non-small cell-lung cancer kn-keyword=non-small cell-lung cancer en-keyword=PD-L1 kn-keyword=PD-L1 en-keyword=pembrolizumab kn-keyword=pembrolizumab en-keyword=poor performance status kn-keyword=poor performance status END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=6 end-page=21 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200119 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tree of motility : A proposed history of motility systems in the tree of life en-subtitle= kn-subtitle= en-abstract= kn-abstract=Motility often plays a decisive role in the survival of species. Five systems of motility have been studied in depth: those propelled by bacterial flagella, eukaryotic actin polymerization and the eukaryotic motor proteins myosin, kinesin and dynein. However, many organisms exhibit surprisingly diverse motilities, and advances in genomics, molecular biology and imaging have showed that those motilities have inherently independent mechanisms. This makes defining the breadth of motility nontrivial, because novel motilities may be driven by unknown mechanisms. Here, we classify the known motilities based on the unique classes of movement‐producing protein architectures. Based on this criterion, the current total of independent motility systems stands at 18 types. In this perspective, we discuss these modes of motility relative to the latest phylogenetic Tree of Life and propose a history of motility. During the ~4 billion years since the emergence of life, motility arose in Bacteria with flagella and pili, and in Archaea with archaella. Newer modes of motility became possible in Eukarya with changes to the cell envelope. Presence or absence of a peptidoglycan layer, the acquisition of robust membrane dynamics, the enlargement of cells and environmental opportunities likely provided the context for the (co)evolution of novel types of motility. en-copyright= kn-copyright= en-aut-name=MiyataMakoto en-aut-sei=Miyata en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=UyedaTaro Q.

We evaluated the efficacy of multifactorial intensive treatment (IT) on renal outcomes in patients with type 2 diabetes and advanced‐stage diabetic kidney disease (DKD).
Materials and Methods
The Diabetic Nephropathy Remission and Regression Team Trial in Japan (DNETT‐Japan) is a multicenter, open‐label, randomized controlled trial with a 5‐year follow‐up period. We randomly assigned 164 patients with advanced‐stage diabetic kidney disease (urinary albumin‐to‐creatinine ratio ≥300 mg/g creatinine, serum creatinine level 1.2–2.5 mg/dL in men and 1.0–2.5 mg/dL in women) to receive either IT or conventional treatment. The primary composite outcome was end‐stage kidney failure, doubling of serum creatinine or death from any cause, which was assessed in the intention‐to‐treat population.
Results
The IT tended to reduce the risk of primary end‐points as compared with conventional treatment, but the difference between treatment groups did not reach the statistically significant level (hazard ratio 0.69, 95% confidence interval 0.43–1.11; P = 0.13). Meanwhile, the decrease in serum low‐density lipoprotein cholesterol level and the use of statin were significantly associated with the decrease in primary outcome (hazard ratio 1.14; 95% confidence interval 1.05–1.23, P < 0.001 and hazard ratio 0.53, 95% confidence interval 0.28–0.998, P < 0.05, respectively). The incidence of adverse events was not different between treatment groups.
Conclusions
The risk of kidney events tended to decrease by IT, although it was not statistically significant. Lipid control using statin was associated with a lower risk of adverse kidney events. Further follow‐up study might show the effect of IT in patients with advanced diabetic kidney disease. en-copyright= kn-copyright= en-aut-name=ShikataKenichi en-aut-sei=Shikata en-aut-mei=Kenichi

proposed by soap‐free emulsion polymerization using a water‐in‐oil (W/O) slug flow in a microreactor. Thin oil films generated around the dispersed aqueous phase of the W/O slug prevent the prepared particles from adhesion to the microchannel wall, enabling the continuous production of PMMA particles without clogging. The effects of the linear flow rate of the slug flow and the addition of ethanol in the dispersed aqueous phase on the polymerization are evaluated. It is found that increasing the linear flow rate of the slug flow or the addition of ethanol in the dispersed aqueous phase results in PMMA particles with high molecular weight (≈1500 kg mol−1) in 20 min reaction time. It is believed that this process would be a promising way to prepare polymer particles with high molecular weight in a short reaction time. en-copyright= kn-copyright= en-aut-name=WatanabeTakaichi en-aut-sei=Watanabe en-aut-mei=Takaichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KaritaKengo en-aut-sei=Karita en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TawaraKoki en-aut-sei=Tawara en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SogaTakuya en-aut-sei=Soga en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OnoTsutomu en-aut-sei=Ono en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Material and Energy Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=heterogeneous polymerization kn-keyword=heterogeneous polymerization en-keyword=internal circulation kn-keyword=internal circulation en-keyword=microreactors kn-keyword=microreactors en-keyword=microspheres kn-keyword=microspheres END start-ver=1.4 cd-journal=joma no-vol=44 cd-vols= no-issue=9 article-no= start-page=1919 end-page=1933 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200521 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=G‐CSF‐dependent neutrophil differentiation requires downregulation of MAPK activities through the Gab2 signaling pathway en-subtitle= kn-subtitle= en-abstract= kn-abstract=Granulocyte colony‐stimulating factor (G‐CSF) stimulation of myeloid cells induced tyrosine‐phosphorylation of cellular proteins. One of the tyrosine‐phosphorylated proteins was found to be a scaffold protein, Grb2‐associated binding protein 2 (Gab2). Another member of Gab family protein, Gab3, was exogenously overexpressed in neutrophil progenitor cells to make the Gab3 protein to compete with the endogenous Gab2 for the G‐CSF‐dependent signaling. In Gab3‐overexpressed cells, the level of tyrosine phosphorylation of endogenous Gab2 by G‐CSF stimulation was markedly downregulated, while the phosphorylation of Gab3 was significantly enhanced. The Gab3‐overexpressed cells continuously proliferated in the medium containing G‐CSF and lost the ability to differentiate to the mature neutrophil, characterized by the lobulated nucleus. The G‐CSF stimulation‐dependent tyrosine phosphorylation of Gab3, the association of SHP2 to Gab3 and the following mitogen‐activated protein kinase (MAPK) activation were prolonged in the Gab3‐overexpressed cells, compared to the parental cells, where the binding of SHP2 to Gab2 protein and thereby the activation of MAPK were not sustained after G‐CSF stimulation. Inhibition of MAPK by pharmaceutical inhibitor restored the Gab3‐overexpressed cells to the ability to differentiate to mature neutrophil. Therefore, G‐CSF‐dependent Gab2 phosphorylation and following its downregulation led the short‐term MAPK activation. The downregulation of MAPK after transient Gab2 phosphorylation was necessary for the consequent neutrophil differentiation induced by G‐CSF stimulation. en-copyright= kn-copyright= en-aut-name=ZhaoXianglin en-aut-sei=Zhao en-aut-mei=Xianglin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawanoShun‐ichiro en-aut-sei=Kawano en-aut-mei=Shun‐ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MasudaJunko en-aut-sei=Masuda en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MurakamiHiroshi en-aut-sei=Murakami en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, 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= 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= en-keyword=granulocyte kn-keyword=granulocyte en-keyword=MAP kinase kn-keyword=MAP kinase en-keyword=negative feedback kn-keyword=negative feedback en-keyword=phosphorylation kn-keyword=phosphorylation en-keyword=scaffold protein kn-keyword=scaffold protein en-keyword=SHP2 kn-keyword=SHP2 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=Ambiguous species boundaries: Hybridization and morphological variation in two closely relatedRubusspecies along altitudinal gradients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although hybridization frequently occurs among plant species, hybrid zones of divergent lineages formed at species boundaries are less common and may not be apparent in later generations of hybrids with more parental-like phenotypes, as a consequence of backcrossing. To determine the effects of dispersal and selection on species boundaries, we compared clines in leaf traits and molecular hybrid index along two hybrid zones on Yakushima Island, Japan, in which a temperate (Rubus palmatus) and subtropical (Rubus grayanus) species of wild raspberry are found. Leaf sinus depth in the two hybrid zones had narrower clines at 600 m a.s.l. than the molecular hybrid index and common garden tests confirmed that some leaf traits, including leaf sinus depth that is a major trait used in species identification, are genetically divergent between these closely related species. The sharp transition in leaf phenotypic traits compared to molecular markers indicated divergent selection pressure on the hybrid zone structure. We suggest that species boundaries based on neutral molecular data may differ from those based on observed morphological traits. en-copyright= kn-copyright= en-aut-name=MimuraMakiko en-aut-sei=Mimura en-aut-mei=Makiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugaMihoko en-aut-sei=Suga en-aut-mei=Mihoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Biology, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Agriculture, Tamagawa University kn-affil= en-keyword=hybrid zone kn-keyword=hybrid zone en-keyword=introgression kn-keyword=introgression en-keyword=morphology kn-keyword=morphology en-keyword=species identification kn-keyword=species identification END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=7 article-no= start-page=1304 end-page=1305 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200413 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Vision loss, tractional retinal detachment, and profound anemia due to rectal carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Profound anemia can cause severe proliferative retinopathy and tractional retinal detachment; therefore, it is important to closely investigate the cause of anemia.

The PACIFIC trial that identified durvalumab as an effective subsequent-line therapy after concurrent chemoradiotherapy (CCRT) found that patients with grade 2 or higher RP may have to be excluded from treatment under certain criteria. The purpose of this study was to investigate the relationship between grade ≥2 RP and the parameters of dose-volume histograms after CCRT with cisplatin/docetaxel for stage III non-small cell lung cancer and conduct a subset analysis of severe RP that can lead to the permanent discontinuation of treatment per the PACIFIC trial criteria to help determine treatment strategy.
Methods: We calculated the percentage of the lung volume received at least 5 Gy (V5) and 20 Gy (V20), the mean lung dose (MLD), and the lung volume spared from a 5 Gy dose (VS5) to the total lung volume. Factors affecting the incidence of grade ≥2 RP were identified; severe RP was defined as grade ≥3 as well as grade 2 RP that required ≥10 mg prednisolone for at least 12 weeks.
Results: This study included 45 patients. On univariate analysis, all parameters and total lung volume were found to be significant predictors of grade ≥2 RP (P = .001, .003, .03, .004, and .02, respectively). On multivariate analysis, V20 was a significant predictive factor of grade ≥2 RP (P = .007). Severe RP developed in 6 of 37 patients (16.2%) whose V20 values were 35% or lower. On univariate analysis, only V20 was a significant predictor of severe RP in these patients (P = .01).
Conclusions: The best approach to reduce the rate of grade ≥2 RP is to maintain the V5, V20, MLD, and VS5 as low as possible during radiotherapy planning in patients receiving definitive CCRT with cisplatin/docetaxel. en-copyright= kn-copyright= en-aut-name=KatsuiKuniaki en-aut-sei=Katsui en-aut-mei=Kuniaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OgataTakeshi en-aut-sei=Ogata en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeKenta en-aut-sei=Watanabe en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatayamaNorihisa en-aut-sei=Katayama en-aut-mei=Norihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KurodaMasahiro en-aut-sei=Kuroda en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 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=8 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=9 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=10 ORCID= affil-num=1 en-affil=Department of Proton Beam Therapy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=2 en-affil=Department of Radiology, Iwakuni Clinical Center 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 Radiological Technology, Graduate School of Health 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 Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=8 en-affil=Department of Hematology, Oncology, and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=9 en-affil=Departments of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=10 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= en-keyword=cisplatin kn-keyword=cisplatin en-keyword=docetaxel kn-keyword=docetaxel en-keyword=dose-volume histogram kn-keyword=dose-volume histogram en-keyword=non-small cell lung cancer kn-keyword=non-small cell lung cancer en-keyword=PACIFIC trial kn-keyword=PACIFIC trial en-keyword=radiation pneumonitis kn-keyword=radiation pneumonitis END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=9 article-no= start-page=1043 end-page=1052 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190319 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Acceleration of bone regeneration of horizontal bone defect in rats using collagen‐binding basic fibroblast growth factor combined with collagen scaffolds en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Basic fibroblast growth factor (bFGF) has been applied for periodontal regeneration. However, the application depends on bone defect morphology because bFGF diffuses rapidly from defect sites. In a previous study, collagen‐binding bFGF (CB‐bFGF) has been shown to enhance bone formation by collagen‐anchoring in the orthopedic field. The aim of this study is to demonstrate the efficacy of CB‐bFGF with collagen scaffolds in bone regeneration of horizontal bone defect.
Methods
Cell proliferation activity and collagen binding activity of CB‐bFGF was confirmed by WST‐8 assay and collagen binding assay, respectively. The retention of CB‐bFGF in the collagen sheet (CS) was measured by fluorescence imaging. The rat horizontal alveolar bone defect model was employed to investigate the efficacy of CB‐bFGF with collagen powder (CP). After 4 and 8 weeks, the regenerative efficacy was evaluated by microcomputed tomography, histological, and immunohistochemical analyses.
Results
CB‐bFGF had a comparable proliferation activity to bFGF and a collagen binding activity. CB‐bFGF was retained in CS longer than bFGF. At 8 weeks postoperation, bone volume, bone mineral content, and new bone area in CB‐bFGF/CP group were significantly increased compared with those in other groups. Furthermore, epithelial downgrowth was significantly suppressed in CB‐bFGF/CP group. At 4 weeks, the numbers of osteocalcin, proliferating cell nuclear antigen, and osteopontin‐positive cells at the regeneration site in CB‐bFGF/CP group were greater than those in other groups.
Conclusions
CB‐bFGF/CP effectively promoted bone regeneration of horizontal bone defect possibly by sustained release of bFGF.

Renal calcified lesions are known as one of the complications during adrenocorticotropic hormone (ACTH) therapy for intractable epilepsy. However, laboratory changes during the therapy or laboratory features of high‐risk cases with renal calcified lesions are yet to be clarified.
Methods
In this study, 43 patients with West syndrome aged ≤2 years were included. We retrospectively reviewed age and body mass index at the beginning of ACTH therapy, as well as the amount of fluid intake, daily urinary volume, and laboratory data during therapy. In addition, we studied the urinary sediment of the cases with renal calcified lesions diagnosed by computed tomography. Results After initiating ACTH treatment, urinary calcium (Ca)/creatinine ratio and urinary pH increased within 2 weeks. Urinary crystals and renal tubular epithelial cells (RTECs) in urinary sediment were frequently found in most cases. Urinary Ca levels, proteinuria or frequency of urinary crystals, and number of RTECs in the urinary sediment were significantly higher in patients with epithelial casts (ECs) or hematuria than in patients without these findings. Among the seven patients who underwent abdominal CT, ECs or hematuria were found only in those with renal calcified lesions. These findings suggested that patients with ECs or hematuria were more likely to have calcified lesions.
Conclusions
The risk of renal calcified lesions increased after 2 weeks of ACTH treatment. Abnormal findings in urinary sediments might be an early sign of renal calcification during ACTH therapy. en-copyright= kn-copyright= en-aut-name=MiyaharaHiroyuki en-aut-sei=Miyahara en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AkiyamaTomoyuki en-aut-sei=Akiyama en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HasegawaKosei en-aut-sei=Hasegawa en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AkiyamaMari en-aut-sei=Akiyama en-aut-mei=Mari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkaMakio en-aut-sei=Oka en-aut-mei=Makio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KobayashiKatsuhiro en-aut-sei=Kobayashi en-aut-mei=Katsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Child Neurology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Child Neurology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Child Neurology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Child Neurology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=adrenocorticotropic hormone therapy kn-keyword=adrenocorticotropic hormone therapy en-keyword=calcium kn-keyword=calcium en-keyword=crystal kn-keyword=crystal en-keyword=renal tubular epithelial cell kn-keyword=renal tubular epithelial cell en-keyword=urinary sediment kn-keyword=urinary sediment END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=5 article-no= start-page=206 end-page=208 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190625 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Myxedema coma accompanied by sick sinus syndrome and hypoventilation: A case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Myxedema coma is an emergency presentation of hypothyroidism, and cardiopulmonary manifestations of the disease are related to a high mortality rate. We herein report a case of myxedema coma accompanied by sick sinus syndrome requiring temporary cardiac pacing and hypercapnic respiratory failure in an 87-year-old woman. This case is unique because both of the cardiac and pulmonary manifestations were reversible and successfully treated with thyroid hormone replacement. Our case indicates that early detection of the condition and administration of levothyroxine are essential to improve the life-threatening condition and avoid invasive treatment such as permanent pacemaker implantation or intubation. en-copyright= kn-copyright= en-aut-name=HaradaKo en-aut-sei=Harada en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MurakamiShuntaro en-aut-sei=Murakami en-aut-mei=Shuntaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TokumasuKazuki en-aut-sei=Tokumasu en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TogawaYu en-aut-sei=Togawa en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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 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 Internal Medicine, Kaneda Hospital kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=hypercapnic respiratory failure kn-keyword=hypercapnic respiratory failure en-keyword=myxedema coma kn-keyword=myxedema coma en-keyword=sick sinus syndrome kn-keyword=sick sinus syndrome END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=8 article-no= start-page=1120 end-page=1128 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200519 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Death feigning as an adaptive anti‐predator behaviour: Further evidence for its evolution from artificial selection and natural populations en-subtitle= kn-subtitle= en-abstract= kn-abstract=Death feigning is considered to be an adaptive antipredator behaviour. Previous studies on Tribolium castaneum have shown that prey which death feign have a fitness advantage over those that do not when using a jumping spider as the predator. Whether these effects are repeatable across species or whether they can be seen in nature is, however, unknown. Therefore, the present study involved two experiments: (a) divergent artificial selection for the duration of death feigning using a related species T. freemani as prey and a predatory bug as predator, demonstrating that previous results are repeatable across both prey and predator species, and (b) comparison of the death‐feigning duration of T. castaneum populations collected from field sites with and without predatory bugs. In the first experiment, T. freemani adults from established selection regimes with longer durations of death feigning had higher survival rates and longer latency to being preyed on when they were placed with predatory bugs than the adults from regimes selected for shorter durations of death feigning. As a result, the adaptive significance of death‐feigning behaviour was demonstrated in another prey–predator system. In the second experiment, wild T. castaneum beetles from populations with predators feigned death longer than wild beetles from predator‐free populations. Combining the results from these two experiments with those from previous studies provided strong evidence that predators drive the evolution of longer death feigning. en-copyright= kn-copyright= en-aut-name=KonishiKana en-aut-sei=Konishi en-aut-mei=Kana 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=SakunoWataru en-aut-sei=Sakuno en-aut-mei=Wataru 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 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= en-keyword= Amphibolus venator kn-keyword= Amphibolus venator en-keyword= antipredator behaviour kn-keyword= antipredator behaviour en-keyword= artificial selection kn-keyword= artificial selection en-keyword= locomotor activity kn-keyword= locomotor activity en-keyword= thanatosis kn-keyword= thanatosis en-keyword= tonic immobility kn-keyword= tonic immobility en-keyword= Tribolium freemani kn-keyword= Tribolium freemani END start-ver=1.4 cd-journal=joma no-vol=35 cd-vols= no-issue=4 article-no= start-page=414 end-page=422 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202004 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prevalence of dementia in people with intellectual disabilities: Cross‐sectional study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background There are only a few studies of the prevalence of dementia in people with intellectual disability (ID) without Down syndrome (DS), and there is a large difference in the prevalences between reported studies. Moreover, the prevalence of mild cognitive impairment (MCI) in ID has not been reported. We aimed to evaluate the prevalence of dementia in adults of all ages and the prevalence of MCI in people with ID. Furthermore, we tried to clarify the differences depending on the various diagnostic criteria. Methods The survey included 493 adults with ID at 28 facilities in Japan. The caregivers answered a questionnaire, and physicians directly examined the participants who were suspected of cognitive decline. Dementia and MCI were diagnosed according to ICD‐10, DC‐LD, and DSM‐5 criteria. Results The prevalence of dementia was 0.8% for the 45 to 54 years old group, 3.5% for the 55 to 64 years old group, and 13.9% for the 65 to 74 years old group in people with ID without DS. The prevalence of MCI was 3.1% for patients 45 to 54, 3.5% for patients 55 to 64, and 2.8% for patients 65 to 74 with ID without DS. DSM‐5 was the most inclusive in diagnosing dementia and MCI in people with ID. Conclusions People with ID without DS may develop dementia and MCI at an earlier age and higher rate than the general population. Among the diagnostic criteria, DSM‐5 was the most useful for diagnosing their cognitive impairment. en-copyright= kn-copyright= en-aut-name=TakenoshitaShintaro en-aut-sei=Takenoshita en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TeradaSeishi en-aut-sei=Terada en-aut-mei=Seishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KuwanoRyozo en-aut-sei=Kuwano en-aut-mei=Ryozo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueTomokazu en-aut-sei=Inoue en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=CyojuAtsushi en-aut-sei=Cyoju en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuemitsuShigeru en-aut-sei=Suemitsu en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamadaNorihito en-aut-sei=Yamada en-aut-mei=Norihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Asahigawaso Research Institute, Asahigawa Medical Welfare Center kn-affil= affil-num=4 en-affil=Asahigawaso Research Institute, Asahigawa Medical Welfare Center kn-affil= affil-num=5 en-affil=Asahigawaso Research Institute, Asahigawa Medical Welfare Center kn-affil= affil-num=6 en-affil=Asahigawaso Research Institute, Asahigawa Medical Welfare Center kn-affil= affil-num=7 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=dementia kn-keyword=dementia en-keyword=intellectual disability kn-keyword=intellectual disability en-keyword=mental retardation kn-keyword=mental retardation en-keyword=mild cognitive impairment kn-keyword=mild cognitive impairment en-keyword=prevalence of dementia kn-keyword=prevalence of dementia END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=6 article-no= start-page=435 end-page=444 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genomic characterization of antibiotic resistance‐encoding genes in clinical isolates of Vibrio cholerae non‐O1/non‐O139 strains from Kolkata, India: generation of novel types of genomic islands containing plural antibiotic resistance genes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Non‐O1/non‐O139 nontoxigenic Vibrio cholerae associated with cholera‐like diarrhea has been reported in Kolkata, India. However, the property involved in the pathogenicity of these strains has remained unclear. The character of 25 non‐O1/non‐O139 nontoxigenic V. cholerae isolated during 8 years from 2007 to 2014 in Kolkata was examined. Determination of the serogroup showed that the serogroups O6, O10, O35, O36, O39, and O70 were represented by two strains in each serogroup, and the remaining isolates belonged to different serogroups. To clarify the character of antibiotic resistance of these isolates, an antibiotic resistance test and the gene analysis were performed. According to antimicrobial drug susceptibility testing, 13 strains were classified as drug resistant. Among them, 10 strains were quinolone resistant and 6 of the 13 strains were resistant to more than three antibiotics. To define the genetic background of the antibiotic character of these strains, whole‐genome sequences of these strains were determined. From the analysis of these sequences, it becomes clear that all quinolone resistance isolates have mutations in quinolone resistance‐determining regions. Further research on the genome sequence showed that four strains possess Class 1 integrons in their genomes, and that three of the four integrons are found to be located in their genomic islands. These genomic islands are novel types. This indicates that various integrons containing drug resistance genes are spreading among V. cholerae non‐O1/non‐O139 strains through the action of newly generated genomic islands. en-copyright= kn-copyright= en-aut-name=MoritaDaichi en-aut-sei=Morita en-aut-mei=Daichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakahashiEizo en-aut-sei=Takahashi en-aut-mei=Eizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoritaMasatomo en-aut-sei=Morita en-aut-mei=Masatomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OhnishiMakoto en-aut-sei=Ohnishi en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MizunoTamaki en-aut-sei=Mizuno en-aut-mei=Tamaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Miyoshi Shin‐ichi en-aut-sei=Miyoshi en-aut-mei= Shin‐ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=DuttaDevarati en-aut-sei=Dutta en-aut-mei=Devarati kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=RamamurthyThandavarayan en-aut-sei=Ramamurthy en-aut-mei=Thandavarayan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ChowdhuryGoutam en-aut-sei=Chowdhury en-aut-mei=Goutam kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=Mukhopadhyay Asish K. en-aut-sei=Mukhopadhyay en-aut-mei= Asish K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OkamotoKeinosuke en-aut-sei=Okamoto en-aut-mei=Keinosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Collaborative Research Center of Okayama University for Infectious Diseases in India, Okayama University kn-affil= affil-num=2 en-affil=Collaborative Research Center of Okayama University for Infectious Diseases in India, Okayama University kn-affil= affil-num=3 en-affil=Department of Bacteriology I, National Institute of Infectious Diseases kn-affil= affil-num=4 en-affil=Department of Bacteriology I, National Institute of Infectious Diseases kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Division of Bacteriology, National Institute of Cholera and Enteric Diseases kn-affil= affil-num=8 en-affil=Center for Human Microbial Ecology, Translational Health Science and Technology Institute kn-affil= affil-num=9 en-affil=Division of Bacteriology, National Institute of Cholera and Enteric Diseases kn-affil= affil-num=10 en-affil=Division of Bacteriology, National Institute of Cholera and Enteric Diseases kn-affil= affil-num=11 en-affil=Collaborative Research Center of Okayama University for Infectious Diseases in India, Okayama University kn-affil= en-keyword=antibiotic resistance kn-keyword=antibiotic resistance en-keyword=diarrhea kn-keyword=diarrhea en-keyword=genome sequence kn-keyword=genome sequence en-keyword=genomic island kn-keyword=genomic island en-keyword=integron kn-keyword=integron en-keyword=Vibrio cholerae kn-keyword=Vibrio cholerae END
