Tumor-associated macrophages (TAMs) have been shown to promote drug resistance. Adenosine-to-inosine RNA-editing, as regulated by adenosine deaminase acting on RNA (ADAR), is a process that induces the posttranscriptional modification of critical oncogenes. The aim of this study is to determine whether the signals from cancer cells would induce RNA-editing in macrophages.
Methods The effects of RNA-editing on phenotypes in macrophages were analyzed using clinical samples and in vitro and in vivo models.
Results The intensity of the RNA-editing enzyme ADAR1 (Adenosine deaminase acting on RNA 1) in cancer and mononuclear cells indicated a strong positive correlation between the nucleus and cytoplasm. The ADAR1-positive mononuclear cells were positive for CD68 and CD163, a marker for M2 macrophages. Cancer cells transport pro-inflammatory cytokines or ADAR1 protein directly to macrophages via the exosomes, promoting RNA-editing in AZIN1 (Antizyme Inhibitor 1) and GLI1 (Glioma-Associated Oncogene Homolog 1) and resulting in M2 macrophage polarization. GLI1 RNA-editing in the macrophages induced by cancer cells promotes the secretion of SPP1, which is supplied to the cancer cells. This activates the NF kappa B pathway in cancer cells, promoting oxaliplatin resistance. When the JAK inhibitors were administered, oncogenic RNA-editing in the macrophages was suppressed. This altered the macrophage polarization from M2 to M1 and decreased oxaliplatin resistance in cancer cells.
Conclusions This study revealed that ADAR1-high TAMs are crucial in regulating drug resistance in CRC and that targeting ADAR1 in TAMs could be a promising treatment approach for overcoming drug resistance in CRC. en-copyright= kn-copyright= en-aut-name=UmedaHibiki en-aut-sei=Umeda en-aut-mei=Hibiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShigeyasuKunitoshi

en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vehicular Ad-Hoc Networks (VANETs) play an essential role in the intelligent transportation era, furnishing users with essential roadway data to facilitate optimal route selection and mitigate the risk of accidents. However, the network exposure makes VANETs susceptible to cyber threats, making authentication crucial for ensuring security and integrity. Therefore, joining entity verification is essential to ensure the integrity and security of communication in VANETs. However, to authenticate the entities, authentication time should be minimized to guarantee fast and secure authentication procedures. We propose an authentication system for VANETs using blockchain and Kerberos for storing authentication messages in a blockchain ledger accessible to Trusted Authentication Servers (TASs) and Roadside Units (RSUs). We evaluate the system in three diverse network scenarios: suburban, urban with 1 TAS, and urban with 2 TASs. The findings reveal that this proposal is applicable in diverse network scenarios to fulfill the network requirements, including authentication, handover, and end-to-end delay, considering an additional TAS for an increasing number of vehicles. The system is also practicable in storing the authentication message in blockchain considering the gas values and memory size for all scenarios. en-copyright= kn-copyright= en-aut-name=RahayuMaya en-aut-sei=Rahayu en-aut-mei=Maya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HossainMd.

RNA detection, primarily through polymerase chain reaction tests, targets the viral genetic material, whereas antigen tests detect N and spike proteins to identify active infections. In addition, antibody tests are performed to measure the immune response, indicating previous exposure or vaccination. Here, we used the developed terahertz chemical microscope (TCM) to detect different concentrations of N protein in solution by immobilizing aptamers on a semiconductor substrate (sensing plate) and demonstrated that the terahertz amplitude varies as the concentration of N proteins increases, exhibiting a highly linear relationship with a coefficient of determination (R2 = 0.9881), indicating that a quantitative measurement of N proteins is achieved. By optimizing the reaction conditions, we confirmed that the amplitude of the terahertz wave was independent of the solution volume. Consequently, trace amounts (0.5 μL) of the N protein were successfully detected, and the detection process only took 10 min. Therefore, this study is expected to develop a rapid and sensitive method for the detection and observation of the SARS-CoV-2 virus at a microdetection level. It is anticipated that this research will significantly contribute to reducing the spread of novel infectious diseases in the future. en-copyright= kn-copyright= en-aut-name=DingXue en-aut-sei=Ding en-aut-mei=Xue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MurakamiMana en-aut-sei=Murakami en-aut-mei=Mana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WangJin en-aut-sei=Wang en-aut-mei=Jin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueHirofumi en-aut-sei=Inoue en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KiwaToshihiko en-aut-sei=Kiwa en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University Hospital kn-affil= affil-num=5 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=terahertz chemical microscope kn-keyword=terahertz chemical microscope en-keyword=aptamers kn-keyword=aptamers en-keyword=N protein kn-keyword=N protein en-keyword=microdetection kn-keyword=microdetection END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=366 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The required experience of open pancreaticoduodenectomy before becoming a specialist in hepatobiliary and pancreatic surgeons: a multicenter, cohort study of 334 open pancreaticoduodenectomies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Open pancreaticoduodenectomy (OPD) is an essential surgical procedure for expert hepato-biliary-pancreatic (HBP) surgeons. However, there is no standard for how many surgeries must be performed by a surgeon in training before they are considered to have enough experience to ensure surgical safety.
Methods Cumulative Sum (CUSUM) analysis was performed using the surgical data of OPDs performed during the training period of board-certified expert surgeons of the Japanese Society of Hepato-Biliary-Pancreatic Surgery.
Results Fourteen HBP surgeons participated in this study and performed 334 OPDs during their training period. The median (interquartile range) values for operative time, blood loss, and length of hospital stay were 455 (397-519) minutes, 450 (234--716) ml, and 28 (21-38) days, respectively. CUSUM analysis showed inflection points at 20 surgeries performed for operative time. After 20 procedures, operative time was significantly shorter (461 min vs. 425 min, p = 0.021) and blood loss was significantly lower (470 ml vs. 340 ml, p = 0.038). No significant differences between within 20 and after 21 procedures were found in the complication rate (53% vs. 48%, p = 0.424) and rate of in-hospital deaths (1.5% vs.1.4%. p = 0.945). Up to 20 surgeries, PDAC and another malignant tumor had longer operative time than benign/low malignant diseases (486 min vs. 472 min vs. 429 min, p < 0.001), and higher blood loss (500 ml vs. 502 ml vs. 355 ml, p < 0.001). Mortality rate was higher at PDAC cases (5% vs. 0% vs. 0%, p = 0.01). After the 21 procedures, these outcomes were improved and no differences in by primary disease were observed. Multivariable analysis showed that within 20 surgeries were independent risk factors of longer operative time (HR2.6, p = 0.013) and higher blood loss (HR2.0, p = 0.049).
Conclusions To stabilize the surgical outcome of OPD for malignant disease, at least 20 surgeries should be performed at a certified institution during surgeon training.

In the budding yeast Saccharomyces cerevisiae, a variety of constitutive and controllable promoters with different strengths have been constructed using endogenous gene promoters, synthetic transcription factors and their binding sequences, and artificial sequences. However, there have been no attempts to construct the highest strength promoter in yeast cells. In this study, by incrementally increasing the binding sequences of the synthetic transcription factor Z3EV, we were able to construct a promoter (P36) with ~1.4 times the strength of the TDH3 promoter. This is stronger than any previously reported promoter. Although the P36 promoter exhibits some leakage in the absence of induction, the expression induction by estradiol is maintained. When combined with a multicopy plasmid, it can express up to ~50% of total protein as a heterologous protein. This promoter system can be used to gain knowledge about the cell physiology resulting from the ultimate overexpression of excess proteins and is expected to be a useful tool for heterologous protein expression in yeast. en-copyright= kn-copyright= en-aut-name=HiguchiRina en-aut-sei=Higuchi en-aut-mei=Rina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujitaYuri en-aut-sei=Fujita en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NambaShotaro en-aut-sei=Namba en-aut-mei=Shotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriyaHisao en-aut-sei=Moriya en-aut-mei=Hisao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=yeast kn-keyword=yeast en-keyword=overexpression kn-keyword=overexpression en-keyword=promoter kn-keyword=promoter END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=1099 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240916 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Histological differences related to autophagy in the minor salivary gland between primary and secondary types of Sj?gren's syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Some forms of Sj?gren’s syndrome (SS) follow a clinical course accompanied by systemic symptoms caused by lymphocyte infiltration and proliferation in the liver, kidneys, and other organs. To better understand the clinical outcomes of SS, here we used minor salivary gland tissues from patients and examine their molecular, biological, and pathological characteristics. A retrospective study was performed, combining clinical data and formalin-fixed paraffin-embedded (FFPE) samples from female patients over 60 years of age who underwent biopsies at Okayama University Hospital. We employed direct digital RNA counting with nCounter? and multiplex immunofluorescence analysis with a PhenoCycler? on the labial gland biopsies. We compared FFPE samples from SS patients who presented with other connective tissue diseases (secondary SS) with those from stable SS patients with symptoms restricted to the exocrine glands (primary SS). Secondary SS tissues showed enhanced epithelial damage and lymphocytic infiltration accompanied by elevated expression of autophagy marker genes in the immune cells of the labial glands. The close intercellular distance between helper T cells and B cells positive for autophagy-associated molecules suggests accelerated autophagy in these lymphocytes and potential B cell activation by helper T cells. These findings indicate that examination of FFPE samples from labial gland biopsies can be an effective tool for evaluating molecular histological differences between secondary and primary SS through multiplexed analysis of gene expression and tissue imaging. en-copyright= kn-copyright= en-aut-name=Ono-MinagiHitomi en-aut-sei=Ono-Minagi en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NohnoTsutomu en-aut-sei=Nohno en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakabatakeKiyofumi en-aut-sei=Takabatake en-aut-mei=Kiyofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatsuyamaTakayuki en-aut-sei=Katsuyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyawakiKohta en-aut-sei=Miyawaki en-aut-mei=Kohta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 ORCID= en-aut-name=IidaSeiji en-aut-sei=Iida en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YoshinoTadashi en-aut-sei=Yoshino en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NagatsukaHitoshi en-aut-sei=Nagatsuka en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=SakaiTakayoshi en-aut-sei=Sakai en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 ORCID= affil-num=1 en-affil=Department of Cytology and Histology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Cytology and Histology, Okayama University Medical School kn-affil= affil-num=3 en-affil=Department of Oral Pathology and Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Hospital kn-affil= affil-num=6 en-affil=Division of Precision Medicine, Kyushu University School of Medicine kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Oral and Maxillofacial Reconstructive Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Pathology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Oral Pathology and Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of Rehabilitation for Orofacial Disorders, Osaka University Graduate School of Dentistry kn-affil= affil-num=13 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Autoimmune disease kn-keyword=Autoimmune disease en-keyword=Xerostomia kn-keyword=Xerostomia en-keyword=Multiplex immunostaining kn-keyword=Multiplex immunostaining en-keyword=Spatial analysis kn-keyword=Spatial analysis en-keyword=Autophagy kn-keyword=Autophagy END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=542 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240815 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluating the impact of a trial of labor after cesarean section on labor duration: a retrospective cohort study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Cesarean section (C-section) rates are increasing globally, and repeated C-sections are associated with increased maternal morbidity. Trial of labor after C-section (TOLAC) is an approach to reduce the recurrence of C-sections. However, limited research exists on the impact of cesarean scars on labor duration in TOLAC, considering the termination of labor through C-section and selection bias. This study aimed to investigate the impact of cesarean scars on labor duration in TOLAC participants, accounting for potential confounding factors and biases.
Methods This retrospective cohort study included 2,964 women who attempted vaginal birth at a single center in Japan from 2012 to 2021. The study categorized participants into TOLAC (n = 187) and non-TOLAC (n = 2,777) groups. Propensity scores were calculated based on 14 factors that could influence labor duration, and inverse probability of treatment weighting (IPTW) was applied. Cox proportional hazards regression analysis estimated hazard ratios (HRs) for labor duration, with and without IPTW adjustment. Sensitivity analyses used propensity score matching, bootstrapping, and interval censoring to address potential biases, including recall bias in the reported onset of labor.
Results The unadjusted HR for labor duration in the TOLAC group compared to the non-TOLAC group was 0.83 (95% CI: 0.70-0.98, P = 0.027), indicating a longer labor duration in the TOLAC group. After adjusting for confounding factors using IPTW, the HR was 0.98 (95% CI: 0.74-1.30, P = 0.91), suggesting no significant difference in labor duration between the groups. Sensitivity analyses using propensity score matching, bootstrapping, and interval censoring yielded consistent results. These findings suggested that the apparent association between TOLAC and longer labor duration was because of confounding factors rather than TOLAC itself.
Conclusions After adjusting for confounding factors and addressing potential biases, cesarean scars had a limited impact on labor duration in TOLAC participants. Maternal and fetal characteristics may have a more substantial influence on labor duration. en-copyright= kn-copyright= en-aut-name=OobaHikaru en-aut-sei=Ooba en-aut-mei=Hikaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MakiJota en-aut-sei=Maki en-aut-mei=Jota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Okayama University Hospital kn-affil= en-keyword=Labor duration kn-keyword=Labor duration en-keyword=Trial of labor after cesarean section kn-keyword=Trial of labor after cesarean section en-keyword=Vaginal birth kn-keyword=Vaginal birth en-keyword=Cesarean section kn-keyword=Cesarean section en-keyword=Propensity scores kn-keyword=Propensity scores en-keyword=IPTW kn-keyword=IPTW END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=341 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240813 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pathological findings in enucleated eyes of patients with neurofibromatosis type 1: report of a case with 15-year follow-up and review of 14 patients in the literature en-subtitle= kn-subtitle= en-abstract= kn-abstract=Backgrounds Iris nodules are frequently noted as clinical manifestations of neurofibromatosis type 1 but the other intraocular manifestations are rare. The purpose of this study is to present a patient with a phthisic eye who underwent enucleation for a cosmetic reason after 15-year follow-up and also to review 14 patients with enucleation described in the literature.
Case presentation A 17-year-old man with neurofibromatosis type 1 from infancy underwent the enucleation of phthisic left eye and also had the resection of eyelid subcutaneous mass lesions on the left side for a cosmetic reason. He had undergone four-time preceding surgeries for eyelid and orbital mass reduction on the left side in childhood and had developed total retinal detachment 10 years previously. Pathologically, the enucleated eye showed massive retinal gliosis positive for both S-100 and glial fibrillary acidic protein (GFAP) in the area with involvement of the detached retinal neuronal layer, together with a more fibrotic lesion along the choroid which were, in contrast, negative for both S-100 and GFAP. The choroid, ciliary body, and iris did not show apparent neurofibroma while episcleral neurofibroma was present.
Literature review In review of enucleated eyes of 14 patients in the literature, buphthalmic eyes with early-onset glaucoma on the unilateral side was clinically diagnosed in 9 patients who frequently showed varying extent of hemifacial neurofibromatosis which involved the eyelid and orbit on the same side. Pathologically, neurofibromas in varying extent were found in the choroid of 12 patients. One patient showed choroidal malignant melanoma on the left side and fusiform enlargement of the optic nerve on the right side suspected of optic nerve glioma. The phthisic eye in another patient showed massive retinal gliosis similar to the present patient.
Conclusions In summary of the 15 patients with neurofibromatosis type 1, including the present patient, buphthalmic or phthisic eyes with no vision were enucleated for cosmetic reasons and showed choroidal neurofibroma in most patients and massive retinal gliosis in two patients including the present patient. 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=NishidaKenji en-aut-sei=Nishida en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SenoTakaya en-aut-sei=Seno en-aut-mei=Takaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamadaKiyoshi en-aut-sei=Yamada en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OnoShigeki en-aut-sei=Ono en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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 Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, General Medical Center, Kawasaki Medical School kn-affil= en-keyword=Neurofibromatosis type 1 kn-keyword=Neurofibromatosis type 1 en-keyword=Enucleation kn-keyword=Enucleation en-keyword=Eye kn-keyword=Eye en-keyword=Pathology kn-keyword=Pathology en-keyword=Massive retinal gliosis kn-keyword=Massive retinal gliosis en-keyword=Choroidal neurofibroma kn-keyword=Choroidal neurofibroma en-keyword=Phthisis kn-keyword=Phthisis en-keyword=Buphthalmos kn-keyword=Buphthalmos en-keyword=Malignant melanoma kn-keyword=Malignant melanoma en-keyword=Cosmetic surgery kn-keyword=Cosmetic surgery END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=13 article-no= start-page=4293 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240701 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Optimizing IoT Intrusion Detection Using Balanced Class Distribution, Feature Selection, and Ensemble Machine Learning Techniques en-subtitle= kn-subtitle= en-abstract= kn-abstract=Internet of Things (IoT) devices are leading to advancements in innovation, efficiency, and sustainability across various industries. However, as the number of connected IoT devices increases, the risk of intrusion becomes a major concern in IoT security. To prevent intrusions, it is crucial to implement intrusion detection systems (IDSs) that can detect and prevent such attacks. IDSs are a critical component of cybersecurity infrastructure. They are designed to detect and respond to malicious activities within a network or system. Traditional IDS methods rely on predefined signatures or rules to identify known threats, but these techniques may struggle to detect novel or sophisticated attacks. The implementation of IDSs with machine learning (ML) and deep learning (DL) techniques has been proposed to improve IDSs' ability to detect attacks. This will enhance overall cybersecurity posture and resilience. However, ML and DL techniques face several issues that may impact the models' performance and effectiveness, such as overfitting and the effects of unimportant features on finding meaningful patterns. To ensure better performance and reliability of machine learning models in IDSs when dealing with new and unseen threats, the models need to be optimized. This can be done by addressing overfitting and implementing feature selection. In this paper, we propose a scheme to optimize IoT intrusion detection by using class balancing and feature selection for preprocessing. We evaluated the experiment on the UNSW-NB15 dataset and the NSL-KD dataset by implementing two different ensemble models: one using a support vector machine (SVM) with bagging and another using long short-term memory (LSTM) with stacking. The results of the performance and the confusion matrix show that the LSTM stacking with analysis of variance (ANOVA) feature selection model is a superior model for classifying network attacks. It has remarkable accuracies of 96.92% and 99.77% and overfitting values of 0.33% and 0.04% on the two datasets, respectively. The model's ROC is also shaped with a sharp bend, with AUC values of 0.9665 and 0.9971 for the UNSW-NB15 dataset and the NSL-KD dataset, respectively. en-copyright= kn-copyright= en-aut-name=MusthafaMuhammad Bisri en-aut-sei=Musthafa en-aut-mei=Muhammad Bisri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HudaSamsul en-aut-sei=Huda en-aut-mei=Samsul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KoderaYuta en-aut-sei=Kodera en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AliMd.

This study aimed to examine the endoscopic characteristics of patients diagnosed with iTAM.
Methods This retrospective analysis included 14 patients pathologically diagnosed with iTAM after stem cell transplantation for hematolymphoid neoplasms (n = 13) or thalassemia (n = 1). The sex, age at diagnosis, endoscopic features, and prognosis of each patient were assessed. Serological markers for diagnosing transplant-associated thrombotic microangiopathy were also evaluated.
Results The mean age at the time of iTAM diagnosis was 40.2 years. Patients diagnosed based on the pathognomonic pathological changes of iTAM presented with diverse symptoms at the times of endoscopic examinations, including diarrhea (n = 10), abdominal pain (n = 5), nausea (n = 4), appetite loss (n = 2), bloody stools (n = 2), abdominal discomfort (n = 1), and vomiting (n = 1). At the final follow-up, six patients survived, while eight patients succumbed, with a median time of 100.5 days (range: 52-247) post-diagnosis. Endoscopic manifestations included erythematous mucosa (n = 14), erosions (n = 13), ulcers (n = 9), mucosal edema (n = 9), granular mucosa (n = 9), and villous atrophy (n = 4). Erosions and/or ulcers were primarily observed in the colon (10/14, 71%), followed by the ileum (9/13, 69%), stomach (4/10, 40%), cecum (5/14, 36%), duodenum (3/10, 30%), rectum (4/14, 29%), and esophagus (1/10, 10%). Cytomegalovirus infection (n = 4) and graft-versus-host disease (n = 2) coexisted within the gastrointestinal tract. Patients had de novo prolonged or progressive thrombocytopenia (6/14, 43%), decreased hemoglobin concentration (4/14, 29%), reduced serum haptoglobin level (3/14, 21%), and a sudden and persistent increase in lactate dehydrogenase level (2/14, 14%). Peripheral blood samples from 12 patients were evaluated for schistocytes, with none exceeding 4%.
Conclusions This study provides a comprehensive exploration of the endoscopic characteristics of iTAM. Notably, all patients exhibited erythematous mucosa throughout the gastrointestinal tract, accompanied by prevalent manifestations, such as erosions (93%), ulcers (64%), mucosal edema (64%), granular mucosa (64%), and villous atrophy (29%). Because of the low positivity for serological markers of transplant-associated thrombotic microangiopathy in patients with iTAM, endoscopic evaluation and biopsy of these lesions are crucial, even in the absence of these serological features. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=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=MatsuokaKen-Ichi en-aut-sei=Matsuoka en-aut-mei=Ken-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=InokuchiToshihiro en-aut-sei=Inokuchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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 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 Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Colonoscopy kn-keyword=Colonoscopy en-keyword=Esophagogastroduodenoscopy kn-keyword=Esophagogastroduodenoscopy en-keyword=Graft-versus-host disease kn-keyword=Graft-versus-host disease en-keyword=Hematopoietic stem cell transplantation kn-keyword=Hematopoietic stem cell transplantation en-keyword=Intestinal transplant-associated microangiopathy kn-keyword=Intestinal transplant-associated microangiopathy en-keyword=iTAM kn-keyword=iTAM END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=7 article-no= start-page=2173 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Application of Throughput Request Satisfaction Method for Maximizing Concurrent Throughput in WLAN for IoT Application System en-subtitle= kn-subtitle= en-abstract= kn-abstract=With the wide applications of the Internet of Things (IoT) in smart home systems, IEEE 802.11n Wireless Local Area Networks (WLANs) have become a frequently chosen communication technology due to their adaptability and affordability. In a high-density network of devices such as the smart home scenerio, a host often meets interferences from other devices and unequal Received Signal Strength (RSS) from Access Points (APs). This results in throughput unfairness/insufficiency problems between hosts communicating concurrently in WLAN. Previously, we have studied the throughput request satisfaction method to address this problem. It calculates the target throughput from measured single and concurrent throughputs of hosts and controls the actual throughput at this target one by applying traffic shaping at the AP. However, the insufficiency problem of maximizing the throughput is not solved due to interferences from other hosts. In this paper, we present an extension of the throughput request satisfaction method to maximize the throughput of a high-priority host under concurrent communications. It recalculates the target throughput to increase the actual throughput as much as possible while the other hosts satisfy the least throughput. For evaluations, we conduct experiments using the test-bed system with Raspberry Pi as the AP devices in several topologies in indoor environments. The results confirm the effectiveness of our proposal. en-copyright= kn-copyright= en-aut-name=WuBin en-aut-sei=Wu en-aut-mei=Bin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=RoySujan Chandra en-aut-sei=Roy en-aut-mei=Sujan Chandra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=RahmanMd.

However, it is unclear whether quality of life (QOL) and activities of daily living (ADL) for survivors of critical illness admitted to the ICU via the emergency department remain consistent or deteriorate in the long-term compared to baseline. This study aimed to evaluate long-term QOL/ADL outcomes in these patients, categorized by the presence or absence of frailty according to Clinical Frailty Scale (CFS) score, as well as explore factors that influence these outcomes.
Methods This was a post-hoc analysis of a prospective, multicenter, observational study conducted across Japan. It included survivors aged 65 years or older who were admitted to the ICU through the emergency department. Based on CFS scores, participants were categorized into either the not frail group or the frail group, using a threshold CFS score of Results Of 514 candidates, 390 participants responded to the EQ-5D-5L questionnaire, while 237 responded to the Barthel Index. At six months post-admission, mean EQ-5D-5L values declined in both the not frail and frail groups (0.80 to 0.73, p?=?0.003 and 0.58 to 0.50, p?=?0.002, respectively); Barthel Index scores also declined in both groups (98 to 83, p? Conclusions Regardless of frailty, older ICU survivors from the emergency department were more likely to experience reduced QOL and ADL six months after ICU admission compared to baseline. 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=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=TaitoShunsuke en-aut-sei=Taito en-aut-mei=Shunsuke 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= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=the LIFE Study Investigators en-aut-sei=the LIFE Study Investigators en-aut-mei= 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, Okayama University Graduate School 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, Okayama University Graduate School 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, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Clinical Practice and Support, Hiroshima University Hospital kn-affil= affil-num=5 en-affil=Department of Epidemiology, 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, Faculty of Medicine, Okayama University Graduate School 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, Okayama University Graduate School 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, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=ADL kn-keyword=ADL en-keyword=Clinical frailty scale kn-keyword=Clinical frailty scale en-keyword=Critical illness kn-keyword=Critical illness en-keyword=Emergency department kn-keyword=Emergency department en-keyword=Intensive care kn-keyword=Intensive care en-keyword=QOL kn-keyword=QOL END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=4 article-no= start-page=1161 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240209 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Enhancement of Outdoor Location-Based Augmented Reality Anchor Precision through VSLAM and Google Street View en-subtitle= kn-subtitle= en-abstract= kn-abstract=Outdoor Location-Based Augmented Reality (LAR) applications require precise positioning for seamless integrations of virtual content into immersive experiences. However, common solutions in outdoor LAR applications rely on traditional smartphone sensor fusion methods, such as the Global Positioning System (GPS) and compasses, which often lack the accuracy needed for precise AR content alignments. In this paper, we introduce an innovative approach to enhance LAR anchor precision in outdoor environments. We leveraged Visual Simultaneous Localization and Mapping (VSLAM) technology, in combination with innovative cloud-based methodologies, and harnessed the extensive visual reference database of Google Street View (GSV), to address the accuracy limitation problems. For the evaluation, 10 Point of Interest (POI) locations were used as anchor point coordinates in the experiments. We compared the accuracies between our approach and the common sensor fusion LAR solution comprehensively involving accuracy benchmarking and running load performance testing. The results demonstrate substantial enhancements in overall positioning accuracies compared to conventional GPS-based approaches for aligning AR anchor content in the real world. en-copyright= kn-copyright= en-aut-name=BrataKomang Candra en-aut-sei=Brata en-aut-mei=Komang Candra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=PandumanYohanes Yohanie Fridelin en-aut-sei=Panduman en-aut-mei=Yohanes Yohanie Fridelin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FajriantiEvianita Dewi en-aut-sei=Fajrianti en-aut-mei=Evianita Dewi 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 Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=location-based kn-keyword=location-based en-keyword=augmented reality kn-keyword=augmented reality en-keyword=SLAM kn-keyword=SLAM en-keyword=cloud-based matching kn-keyword=cloud-based matching en-keyword=Android kn-keyword=Android END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=2 article-no= start-page=548 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240115 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Ultrathin Platinum Film Hydrogen Sensors with a Twin-T Type Notch Filter Circuit en-subtitle= kn-subtitle= en-abstract= kn-abstract=In recent years, hydrogen energy has garnered attention as a potential solution for mitigating greenhouse gas emissions. However, concerns regarding the inherent risk of hydrogen gas leakage and potential explosions have necessitated the development of advanced sensors. Within our research group, we have innovated an ultrathin platinum (Pt) film hydrogen sensor that gauges resistance changes in Pt thin films when exposed to hydrogen gas. Notably, the sensitivity of each sensor is contingent upon the thickness of the Pt film. To address the challenge of detecting hydrogen using multiple sensors, we integrated the ultrathin Pt film as a resistance element within a twin-T type notch filter. This filter exhibits a distinctive reduction in output signals at a specific frequency. The frequency properties of the notch filter dynamically alter with changes in the resistance of the Pt film induced by hydrogen exposure. Consequently, the ultrathin Pt film hydrogen sensor monitors output signal variations around the notch frequency, responding to shifts in frequency properties. This innovative approach enables the electrical control of sensor sensitivity by adjusting the operating frequency in proximity to the notch frequency. Additionally, the simultaneous detection of hydrogen by multiple sensors was successfully achieved by interconnecting sensors with distinct notch frequencies in series. en-copyright= kn-copyright= en-aut-name=WakabayashiShoki en-aut-sei=Wakabayashi en-aut-mei=Shoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhYuki en-aut-sei=Oh en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakayamaHaruhito en-aut-sei=Nakayama en-aut-mei=Haruhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangJin en-aut-sei=Wang en-aut-mei=Jin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KiwaToshihiko en-aut-sei=Kiwa en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=hydrogen sensor kn-keyword=hydrogen sensor en-keyword=ultrathin film kn-keyword=ultrathin film en-keyword=twin-T kn-keyword=twin-T en-keyword=notch filter kn-keyword=notch filter en-keyword=platinum kn-keyword=platinum END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=55 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Influence of the coronavirus disease 2019 pandemic on the post-graduate career paths of medical students: a cross-sectional study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background The World Health Organization first declared the coronavirus disease 2019 (COVID-19) pandemic in March 2020 and announced the end of the emergency in May 2023. Additionally, the COVID-19 pandemic significantly impacted individuals globally, including medical students. Although the COVID-19 pandemic increased online education, it restricted clinical training, extracurricular activities, and interprovincial travel. Therefore, this study aimed to examine whether the COVID-19 pandemic influenced the choice of training hospitals and career paths among 3rd- to 6th-year medical students in Japan.
Methods We developed a questionnaire comprising 21 multiple-choice and 1 open-ended questions, which was administered anonymously via online platforms. The survey targeted Japanese medical students to obtain insights into their preferences for training hospitals and career paths during the COVID-19 pandemic. Participants included 4th- to 6th-year medical students from 51 medical schools in Japan. The survey was conducted through student networks from 8 February 2022 to 20 March 2022.
Results Overall, 507 medical students participated in the survey, with representation from various academic years as follows: 102 (20.1%), 134 (26.4%), 121 (23.9%), and 150 (29.6%) students from the 3rd, 4th, 5th, and 6th year, respectively. Of these, 338 (66.6%) students reported that the COVID-19 pandemic had influenced their choice of training hospitals. The degree of the influence varied based on the university region and the student year. However, most of the students (473, 93.3%) did not change their course for clinical, basic research, or administrative pathways due to the COVID-19 pandemic. Among the clinically oriented students, 391 (77.2%) did not change their preferred speciality.
Conclusions The COVID-19 pandemic influenced medical students' choice of training hospitals. Although many students believed that the pandemic would not change their career choices, our results indicate a potential subconscious trend to avoid internal medicine, which is the speciality most directly involved in treating patients with COVID-19. en-copyright= kn-copyright= en-aut-name=NishimuraAyumu en-aut-sei=Nishimura en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyoshiTomoko en-aut-sei=Miyoshi en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Okayama University Medical School Faculty of Medicine kn-affil= affil-num=2 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=COVID-19 pandemic kn-keyword=COVID-19 pandemic en-keyword=Medical students kn-keyword=Medical students en-keyword=Career path kn-keyword=Career path en-keyword=Training hospitals kn-keyword=Training hospitals END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=18 article-no= start-page=14128 end-page= 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=Advanced Techniques Using In Vivo Electroporation to Study the Molecular Mechanisms of Cerebral Development Disorders en-subtitle= kn-subtitle= en-abstract= kn-abstract=The mammalian cerebral cortex undergoes a strictly regulated developmental process. Detailed in situ visualizations, imaging of these dynamic processes, and in vivo functional gene studies significantly enhance our understanding of brain development and related disorders. This review introduces basic techniques and recent advancements in in vivo electroporation for investigating the molecular mechanisms underlying cerebral diseases. In utero electroporation (IUE) is extensively used to visualize and modify these processes, including the forced expression of pathological mutants in human diseases; thus, this method can be used to establish animal disease models. The advent of advanced techniques, such as genome editing, including de novo knockout, knock-in, epigenetic editing, and spatiotemporal gene regulation, has further expanded our list of investigative tools. These tools include the iON expression switch for the precise control of timing and copy numbers of exogenous genes and TEMPO for investigating the temporal effects of genes. We also introduce the iGONAD method, an improved genome editing via oviductal nucleic acid delivery approach, as a novel genome-editing technique that has accelerated brain development exploration. These advanced in vivo electroporation methods are expected to provide valuable insights into pathological conditions associated with human brain disorders. en-copyright= kn-copyright= en-aut-name=YangChen en-aut-sei=Yang en-aut-mei=Chen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShitamukaiAtsunori en-aut-sei=Shitamukai en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YangShucai en-aut-sei=Yang en-aut-mei=Shucai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawaguchiAyano en-aut-sei=Kawaguchi en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Human Morphology, Okayama University Graduate School of Medicine, Density and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Human Morphology, Okayama University Graduate School of Medicine, Density and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Human Anatomy and Histology and Embryology, School of Basic Medicine, Harbin Medical University kn-affil= affil-num=4 en-affil=Department of Human Morphology, Okayama University Graduate School of Medicine, Density and Pharmaceutical Sciences kn-affil= en-keyword=in vivo electroporation kn-keyword=in vivo electroporation en-keyword=in utero electroporation kn-keyword=in utero electroporation en-keyword=genome editing kn-keyword=genome editing en-keyword=IUE kn-keyword=IUE en-keyword=iON kn-keyword=iON en-keyword=TEMPO kn-keyword=TEMPO en-keyword=iGONAD kn-keyword=iGONAD END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=24 article-no= start-page=17294 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231209 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Positive Regulation of S-Adenosylmethionine on Chondrocytic Differentiation via Stimulation of Polyamine Production and the Gene Expression of Chondrogenic Differentiation Factors en-subtitle= kn-subtitle= en-abstract= kn-abstract=S-adenosylmethionine (SAM) is considered to be a useful therapeutic agent for degenerative cartilage diseases, although its mechanism is not clear. We previously found that polyamines stimulate the expression of differentiated phenotype of chondrocytes. We also found that the cellular communication network factor 2 (CCN2) played a huge role in the proliferation and differentiation of chondrocytes. Therefore, we hypothesized that polyamines and CCN2 could be involved in the chondroprotective action of SAM. In this study, we initially found that exogenous SAM enhanced proteoglycan production but not cell proliferation in human chondrocyte-like cell line-2/8 (HCS-2/8) cells. Moreover, SAM enhanced gene expression of cartilage-specific matrix (aggrecan and type II collagen), Sry-Box transcription factor 9 (SOX9), CCN2, and chondroitin sulfate biosynthetic enzymes. The blockade of the methionine adenosyltransferase 2A (MAT2A) enzyme catalyzing intracellular SAM biosynthesis restrained the effect of SAM on chondrocytes. The polyamine level in chondrocytes was higher in SAM-treated culture than control culture. Additionally, Alcian blue staining and RT-qPCR indicated that the effects of SAM on the production and gene expression of aggrecan were reduced by the inhibition of polyamine synthesis. These results suggest that the stimulation of polyamine synthesis and gene expression of chondrogenic differentiation factors, such as CCN2, account for the mechanism underlying the action of SAM on chondrocytes. en-copyright= kn-copyright= en-aut-name=HoangLoc Dinh en-aut-sei=Hoang en-aut-mei=Loc Dinh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AoyamaEriko en-aut-sei=Aoyama en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiasaMiki en-aut-sei=Hiasa en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OmoteHiroshi en-aut-sei=Omote en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=KubokiTakuo en-aut-sei=Kuboki en-aut-mei=Takuo 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= affil-num=1 en-affil=Advanced Research Center for Oral and Craniofacial Sciences (ARCOCS), Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Advanced Research Center for Oral and Craniofacial Sciences (ARCOCS), Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Laboratory of Membrane Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Laboratory of Membrane Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Advanced Research Center for Oral and Craniofacial Sciences (ARCOCS), Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=S-adenosylmethionine kn-keyword=S-adenosylmethionine en-keyword=chondrocyte differentiation kn-keyword=chondrocyte differentiation en-keyword=CCN2 kn-keyword=CCN2 en-keyword=polyamine kn-keyword=polyamine en-keyword=ODC kn-keyword=ODC en-keyword=gene expression kn-keyword=gene expression END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=20 article-no= start-page=15450 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231022 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Roles of Oxidative Injury and Nitric Oxide System Derangements in Kawasaki Disease Pathogenesis: A Systematic Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Kawasaki disease (KD) is an acute febrile vasculitis that occurs mostly in children younger than five years. KD involves multiple intricately connected inflammatory reactions activated by a cytokine cascade. Despite therapeutic advances, coronary artery damage may develop in some patients, who will be at risk of clinical cardiovascular events and even sudden death. The etiology of KD remains unclear; however, it may involve both genetic and environmental factors leading to aberrant inflammatory responses. Given the young age of onset, prenatal or perinatal exposure may be etiologically relevant. Multisystem inflammatory syndrome in children, a post-infectious hyper-inflammatory disorder associated with severe acute respiratory syndrome coronavirus 2, has features that overlap with those of KD. Available evidence indicates that vascular endothelial dysfunction is a critical step in the sequence of events leading to the development of cardiovascular lesions in KD. Oxidative stress and the dysregulation of the nitric oxide (NO) system contribute to the pathogenesis of inflammatory responses related to this disease. This review provides current evidence and concepts highlighting the adverse effects of oxidative injury and NO system derangements on the initiation and progression of KD and potential therapeutic strategies for cardiovascular pathologies in affected children. en-copyright= kn-copyright= en-aut-name=TsugeMitsuru en-aut-sei=Tsuge en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UdaKazuhiro en-aut-sei=Uda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EitokuTakahiro en-aut-sei=Eitoku en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=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= 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 Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pediatrics, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of Epidemiology, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Epidemiology, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=biomarker kn-keyword=biomarker en-keyword=coronary artery lesions kn-keyword=coronary artery lesions en-keyword=Kawasaki disease kn-keyword=Kawasaki disease en-keyword=multisystem inflammatory syndrome in children kn-keyword=multisystem inflammatory syndrome in children en-keyword=nitric oxide kn-keyword=nitric oxide en-keyword=nitrosative stress kn-keyword=nitrosative stress en-keyword=oxidative stress kn-keyword=oxidative stress en-keyword=systemic inflammation kn-keyword=systemic inflammation en-keyword=vascular endothelial dysfunction kn-keyword=vascular endothelial dysfunction END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=80 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231004 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Radiation in an emergency situation: attempting to respect the patient's beliefs as reported by a minor en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background　Each individual's unique health-related beliefs can greatly impact the patient-clinician relationship. When there is a conflict between the patient's preferences and recommended medical care, it can create a serious ethical dilemma, especially in an emergency setting, and dramatically alter this important relationship.
Case presentation　A 56-year-old man, who remained comatose after out-of-hospital cardiac arrest, was rushed to our hospital. The patient was scheduled for emergency coronary angiography when his adolescent daughter reported that she and her father held sincere beliefs against radiation exposure. We were concerned that she did not fully understand the potential consequences if her father did not receive the recommended treatment. A physician provided her with in depth information regarding the risks and benefits of the treatment. While we did not want to disregard her statement, we opted to save the patient's life due to concerns about the validity of her report.
Conclusions　Variations in beliefs regarding medical care force clinicians to incorporate patient beliefs into medical practice. However, an emergency may require a completely different approach. When faced with a patient in a life-threatening condition and unconscious, we should take action to prioritize saving their life, unless we are highly certain about the validity of their advance directives. 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=KoideYasuhiro en-aut-sei=Koide en-aut-mei=Yasuhiro 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=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, 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= en-keyword=Emergency service kn-keyword=Emergency service en-keyword=Informed consent kn-keyword=Informed consent en-keyword=Radiation kn-keyword=Radiation en-keyword=Treatment refusal kn-keyword=Treatment refusal END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=727 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=Increased quadriceps muscle strength after medial meniscus posterior root repair is associated with decreased medial meniscus extrusion progression en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background　This study aimed to assess quadriceps muscle strength after medial meniscus (MM) posterior root repair and determine its relationship with clinical scores and MM extrusion (MME).
Methods　Thirty patients who underwent pullout repair for MM posterior root tear and were evaluated for quadriceps muscle strength preoperatively and at 1 year postoperatively were included in this study. Quadriceps muscle strength was measured using the Locomo Scan-II instrument (ALCARE, Tokyo, Japan). MME and clinical scores (i.e., Knee Injury and Osteoarthritis Outcome Score [KOOS], International Knee Documentation Committee score, Lysholm score, Tegner score, and visual analog scale pain score) were evaluated preoperatively and at 1 year postoperatively, and second-look arthroscopy was performed at 1 year postoperatively. Wilcoxon ' s signed-rank test was used to compare each measure pre-and postoperatively. Pearson ' s correlation coefficient was used to assess the correlation with quadriceps muscle strength values. Multiple regression analysis was performed to identify factors associated with the change in MME (.MME).
Results　Second-look arthroscopy confirmed continuity of the posterior root in all patients. The quadriceps muscle strength measured at 1 year postoperatively (355.1 +/- 116.2 N) indicated significant improvement relative to the quadriceps muscle strength measured preoperatively (271.9 +/- 97.4 N, p < 0.001). The MME at 1 year postoperatively (4.59 +/- 1.24 mm) had progressed significantly relative to the MME preoperatively (3.63 +/- 1.01 mm, p < 0.001). The clinical scores at 1 year postoperatively were improved significantly relative to the scores preoperatively (p < 0.001). The postoperative quadriceps muscle strength was correlated with.MME (correlation coefficient = -0.398, p = 0.030), and the change in quadriceps muscle strength was correlated with the KOOS-Quality of Life (correlation coefficient = 0.430, p = 0.018). Multiple regression analysis showed that the postoperative quadriceps muscle strength had a significant effect on.MME even when the body mass index and time from injury to surgery were included.
Conclusions　After MM posterior root repair, patients with greater quadriceps muscle strength showed less MME progression. In addition, patients with greater improvement in quadriceps muscle strength had better clinical scores; therefore, continued rehabilitation aimed at improving quadriceps muscle strength after MM posterior root repair is recommended. en-copyright= kn-copyright= en-aut-name=KawadaKoki en-aut-sei=Kawada en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukubaMikao en-aut-sei=Fukuba en-aut-mei=Mikao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TamuraMasanori en-aut-sei=Tamura en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HigashiharaNaohiro en-aut-sei=Higashihara en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YokoyamaYusuke en-aut-sei=Yokoyama en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KatayamaYoshimi en-aut-sei=Katayama en-aut-mei=Yoshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HamadaMasanori en-aut-sei=Hamada en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Clinical score kn-keyword=Clinical score en-keyword=Medial meniscus kn-keyword=Medial meniscus en-keyword=Medial meniscus extrusion kn-keyword=Medial meniscus extrusion en-keyword=Muscle strength kn-keyword=Muscle strength en-keyword=Posterior root tear kn-keyword=Posterior root tear en-keyword=Quadriceps kn-keyword=Quadriceps END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=5 article-no= start-page=382 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220913 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Investigation of bone invasion and underlying mechanisms of oral cancer using a cell line?derived xenograft model en-subtitle= kn-subtitle= en-abstract= kn-abstract=The cancer stroma regulates bone invasion in oral squamous cell carcinoma (OSCC). However, data on normal stroma are limited. In the present study, the effects of gingival and periodontal ligament tissue?derived stromal cells (G?SCs and P?SCs, respectively) and human dermal fibroblasts (HDFs) on bone resorption and osteoclast activation were assessed using hematoxylin and eosin and tartrate?resistant acid phosphatase staining in a cell line?derived xenograft model. The results demonstrated that G?SCs promoted bone invasion and osteoclast activation and inhibited osteoclast proliferation following crosstalk with the human OSCC HSC?3 cell line, whereas P?SCs inhibited bone resorption and promoted osteoclast proliferation in vitro but had a minimal effect on osteoclast activation both in vitro and in vivo following crosstalk with HSC?3 cells. Furthermore, the effects of G?SCs, P?SCs and HDFs on protein expression levels of matrix metalloproteinase (MMP)?9, membrane type 1 MMP (MT1?MMP), Snail, parathyroid hormone?related peptide (PTHrP) and receptor activator of NF?κB ligand (RANKL) in HSC?3 cells in OSCC bone invasion regions were assessed using immunohistochemistry. The results demonstrated that G?SCs had a more prominent effect on the expression of MMP?9, MT1?MMP, Snail, PTHrP, and RANKL, whereas P?SCs only promoted RANKL and PTHrP expression and exerted a minimal effect on MMP?9, MT1?MMP and Snail expression. The potential genes underlying the differential effects of G?SCs and P?SCs on bone invasion in OSCC were evaluated using a microarray, which indicated that cyclin?dependent kinase 1, insulin, aurora kinase A, cyclin B1 and DNA topoisomerase II alpha underlaid these differential effects. Therefore, these results demonstrated that G?SCs promoted bone invasion in OSCC by activating osteoclasts on the bone surface, whereas P?SCs exerted an inhibitory effect. These findings could indicate a potential regulatory mechanism for bone invasion in OSCC. en-copyright= kn-copyright= en-aut-name=ShanQiusheng en-aut-sei=Shan en-aut-mei=Qiusheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakabatakeKiyofumi en-aut-sei=Takabatake en-aut-mei=Kiyofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OmoriHaruka en-aut-sei=Omori en-aut-mei=Haruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawaiHotaka en-aut-sei=Kawai en-aut-mei=Hotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OoMay Wathone en-aut-sei=Oo en-aut-mei=May Wathone kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SukegawaShintaro en-aut-sei=Sukegawa en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujiiMasae en-aut-sei=Fujii en-aut-mei=Masae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=InadaYasunori en-aut-sei=Inada en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SanoSho en-aut-sei=Sano en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakanoKeisuke en-aut-sei=Nakano en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NagatsukaHitoshi en-aut-sei=Nagatsuka en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Oral Pathology and Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=oral squamous cell carcinoma kn-keyword=oral squamous cell carcinoma en-keyword=bone invasion kn-keyword=bone invasion en-keyword=gingival ligament tissue?derived stromal cell kn-keyword=gingival ligament tissue?derived stromal cell en-keyword=periodontal ligament tissue?derived stromal cell kn-keyword=periodontal ligament tissue?derived stromal cell en-keyword=xenograft model kn-keyword=xenograft model en-keyword=microarray kn-keyword=microarray END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=18 article-no= start-page=13692 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230905 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Germinal Origin of Salivary and Lacrimal Glands and the Contributions of Neural Crest Cell-Derived Epithelium to Tissue Regeneration en-subtitle= kn-subtitle= en-abstract= kn-abstract=The vertebrate body comprises four distinct cell populations: cells derived from (1) ectoderm, (2) mesoderm, (3) endoderm, and (4) neural crest cells, often referred to as the fourth germ layer. Neural crest cells arise when the neural plate edges fuse to form a neural tube, which eventually develops into the brain and spinal cord. To date, the embryonic origin of exocrine glands located in the head and neck remains under debate. In this study, transgenic TRiCK mice were used to investigate the germinal origin of the salivary and lacrimal glands. TRiCK mice express fluorescent proteins under the regulatory control of Sox1, T/Brachyury, and Sox17 gene expressions. These genes are representative marker genes for neuroectoderm (Sox1), mesoderm (T), and endoderm (Sox17). Using this approach, the cellular lineages of the salivary and lacrimal glands were examined. We demonstrate that the salivary and lacrimal glands contain cells derived from all three germ layers. Notably, a subset of Sox1-driven fluorescent cells differentiated into epithelial cells, implying their neural crest origin. Also, these Sox1-driven fluorescent cells expressed high levels of stem cell markers. These cells were particularly pronounced in duct ligation and wound damage models, suggesting the involvement of neural crest-derived epithelial cells in regenerative processes following tissue injury. This study provides compelling evidence clarifying the germinal origin of exocrine glands and the contribution of neural crest-derived cells within the glandular epithelium to the regenerative response following tissue damage. en-copyright= kn-copyright= en-aut-name=Ono-MinagiHitomi en-aut-sei=Ono-Minagi en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NohnoTsutomu en-aut-sei=Nohno en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SerizawaTakashi en-aut-sei=Serizawa en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UsamiYu en-aut-sei=Usami en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakaiTakayoshi en-aut-sei=Sakai en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkanoHideyuki en-aut-sei=Okano en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Department of Cytology and Histology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cytology and Histology, Okayama University Medical School kn-affil= affil-num=3 en-affil=Department of Physiology, Keio University School of Medicine kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Pathology, Osaka University Graduate School of Dentistry kn-affil= affil-num=5 en-affil=Department of Rehabilitation for Orofacial Disorders, Osaka University Graduate School of Dentistry kn-affil= affil-num=6 en-affil=Department of Physiology, Keio University School of Medicine kn-affil= affil-num=7 en-affil=Department of Cytology and Histology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=salivary and lacrimal glands kn-keyword=salivary and lacrimal glands en-keyword=development kn-keyword=development en-keyword=three germ layers kn-keyword=three germ layers en-keyword=neural crest kn-keyword=neural crest END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=4 article-no= start-page=345 end-page= 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=Effect of bacterium in the malignant wounds of soft tissue sarcoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Malignant wounds (MWs) are rare skin lesions, which accompany ulceration, necrosis and infection caused by infiltration or damage by malignant tumor. The present study aimed to investigate the bacterial etiology implicated in MW in soft tissue sarcoma (STS), and the effectiveness of culture?guided perioperative antibacterial administration. A retrospective evaluation was conducted on medical records of patients who presented with MW between 2006 and 2020. A total of seven patients were included in the present study, in whom all tumors were relatively large (>5 cm) and high?grade. Subsequently, five patients underwent limb?sparing surgery, and three patients had distant metastases with a 5?year overall survival of 71%. Preoperative microbiological sampling from the wound identified 11 different bacterial strains in five patients. The infections were polymicrobial with an average of 2.6 strains isolated per patient (1 aerobic, 1.6 anaerobic bacteria). They were predominantly methicillin?sensitive Staphylococcus aureus. Patients with MWs from STS reported symptoms, including bleeding (71%), exudation (71%) and malodorous wound (43%) at the initial presentation; these completely resolved after surgery. All but one patient reported pain at the MW site with an average numeric rating scale of 4.4 at presentation that decreased to 1.4 (P=0.14) and 0.6 (P=0.04) one and two weeks after surgery, respectively. The patients had elevated C?reactive protein (71%), anemia (57%), low albumin (86%) and renal/liver dysfunction (14?29%). One patient was diagnosed with sepsis. Surgical resection afforded symptomatic relief and resolution of abnormal laboratory values. Although selected antibiotics were administered in four patients based on the preoperative antibiotic sensitivity test, surgical site infection (SSI) occurred in three patients. Therefore, the effectiveness of the selected antibiotics based on the results of the preoperative culture in preventing SSI needs to be investigated in the future. In conclusion, physicians should keep in mind that although surgical resection can improve the symptoms and abnormal values in laboratory examination form MW, it is accompanied with a high rate of SSI and poor prognosis. en-copyright= kn-copyright= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 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=4 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=5 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=6 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= en-keyword=malignant wounds kn-keyword=malignant wounds en-keyword=soft tissue sarcoma kn-keyword=soft tissue sarcoma en-keyword=microbiological analysis kn-keyword=microbiological analysis en-keyword=surgical site infection kn-keyword=surgical site infection en-keyword=prognosis kn-keyword=prognosis END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=3 article-no= start-page=319 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220719 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinicopathological and histological analysis of secondary malignant giant cell tumors of bone without radiotherapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Giant cell tumor of bone (GCTB) is an intermediate bone tumor that rarely undergoes malignant transformation. Secondary malignant GCTB (SMGCTB) is defined as a lesion in which high?grade sarcoma occurs at the site of previously treated GCTB. The present study retrospectively reviewed the medical records of patients with GCTB treated at Okayama University Hospital between April 1986 and April 2020. The clinicopathological and histological features of patients with SMGCTB without prior radiotherapy were investigated. A total of three patients (4%) with SMGCTB were detected, and the tumor sites were the distal ulna, distal femur and sacrum. Two of the patients had been treated with curettage and bone graft, and one had been treated with denosumab. In all cases, the lesions were made up of two components, the conventional GCTB component and the malignant component. The Ki67 labeling index was higher in the malignant components of SMGCTB and metastatic lesions compared with that in primary and recurrent conventional GCTB, or the conventional GCTB component of SMGCTB. Moreover, p53 expression was higher in these same components in patients who underwent curettage and bone grafting; however, there was no difference in the patient that received denosumab treatment. In this patient, clinical cancer genomic profiling revealed loss of CDKN2A, CDKN2B and MTAP expression. All three patients developed distant metastasis. The patients with SMGCTB in the ulna and femur died 13 and 54 months after detection of malignant transformation, respectively. The patient with SMGCTB in the sacrum received carbon?ion radiotherapy to the sacrum and pazopanib; the treatment was effective and the patient was alive at the last follow?up 3 years later. In conclusion, p53 may be associated with malignant transformation in GCTB. Future studies should investigate the association of between denosumab treatment and malignant transformation, as well as molecular targeted therapy to improve the clinical outcomes of SMGCTB. en-copyright= kn-copyright= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawaiHotaka en-aut-sei=Kawai en-aut-mei=Hotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 ORCID= en-aut-name=InoueHirofumi en-aut-sei=Inoue en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FutagawaMashu en-aut-sei=Futagawa en-aut-mei=Mashu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=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 Hospital kn-affil= affil-num=2 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Clinical Genomic Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= en-keyword=giant cell tumor of bone kn-keyword=giant cell tumor of bone en-keyword=malignant transformation kn-keyword=malignant transformation en-keyword=p53 kn-keyword=p53 en-keyword=denosumab kn-keyword=denosumab en-keyword=molecular targeted therapy kn-keyword=molecular targeted therapy END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=8 article-no= start-page=1429 end-page=1438 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220518 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Rationale, design and baseline characteristics of the effect of canagliflozin in patients with type 2 diabetes and microalbuminuria in the Japanese 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.

en-subject= kn-subject= en-title= kn-title=Interaction of Orexin and Bone Morphogenetic Proteins in Steroidogenesis by Human Adrenocortical Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Orexins are neuropeptides that play important roles in sleep-wake regulation and food intake in the central nervous system, but their receptors are also expressed in peripheral tissues, including the endocrine system. In the present study, we investigated the functions of orexin in adrenal steroidogenesis using human adrenocortical H295R cells by focusing on its interaction with adrenocortical bone morphogenetic proteins (BMPs) that induce adrenocortical steroidogenesis. Treatment with orexin A increased the mRNA levels of steroidogenic enzymes including StAR, CYP11B2, CYP17, and HSD3B1, and these effects of orexin A were further enhanced in the presence of forskolin. Interestingly, orexin A treatment suppressed the BMP-receptor signaling detected by Smad1/5/9 phosphorylation and Id-1 expression through upregulation of inhibitory Smad7. Orexin A also suppressed endogenous BMP-6 expression but increased the expression of the type-II receptor of ActRII in H295R cells. Moreover, treatment with BMP-6 downregulated the mRNA level of OX1R, but not that of OX2R, expressed in H295R cells. In conclusion, the results indicate that both orexin and BMP-6 accelerate adrenocortical steroidogenesis in human adrenocortical cells; both pathways mutually inhibit each other, thereby leading to a fine-tuning of adrenocortical steroidogenesis. en-copyright= kn-copyright= en-aut-name=SoejimaYoshiaki en-aut-sei=Soejima en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwataNahoko en-aut-sei=Iwata en-aut-mei=Nahoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishiokaRan en-aut-sei=Nishioka en-aut-mei=Ran kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HondaMako en-aut-sei=Honda en-aut-mei=Mako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamamotoKoichiro en-aut-sei=Yamamoto en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuyamaAtsuhito en-aut-sei=Suyama en-aut-mei=Atsuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Medicine, 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= affil-num=8 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=bone morphogenetic protein (BMP) kn-keyword=bone morphogenetic protein (BMP) en-keyword=orexin kn-keyword=orexin en-keyword=steroidogenesis and adrenal kn-keyword=steroidogenesis and adrenal END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=14 article-no= start-page=11768 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230721 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of Hydrophobic Cell-Penetrating Stapled Peptides as Drug Carriers en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cell-penetrating peptides (CPPs) are widely used for the intracellular delivery of a variety of cargo molecules, including small molecules, peptides, nucleic acids, and proteins. Many cationic and amphiphilic CPPs have been developed; however, there have been few reports regarding hydrophobic CPPs. Herein, we have developed stapled hydrophobic CPPs based on the hydrophobic CPP, TP10, by introducing an aliphatic carbon side chain on the hydrophobic face of TP10. This side chain maintained the hydrophobicity of TP10 and enhanced the helicity and cell penetrating efficiency. We evaluated the preferred secondary structures, and the ability to deliver 5(6)-carboxyfluorescein (CF) as a model small molecule and plasmid DNA (pDNA) as a model nucleotide. The stapled peptide F-3 with CF, in which the stapling structure was introduced at Gly residues, formed a stable & alpha;-helical structure and the highest cell-membrane permeability via an endocytosis process. Meanwhile, peptide F-4 demonstrated remarkable stability when forming a complex with pDNA, making it the optimal choice for the efficient intracellular delivery of pDNA. The results showed that stapled hydrophobic CPPs were able to deliver small molecules and pDNA into cells, and that different stapling positions in hydrophobic CPPs can control the efficiency of the cargo delivery. en-copyright= kn-copyright= en-aut-name=TsuchiyaKeisuke en-aut-sei=Tsuchiya en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HorikoshiKanako en-aut-sei=Horikoshi en-aut-mei=Kanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujitaMinami en-aut-sei=Fujita en-aut-mei=Minami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiranoMotoharu en-aut-sei=Hirano en-aut-mei=Motoharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyamotoMaho en-aut-sei=Miyamoto en-aut-mei=Maho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YokooHidetomo en-aut-sei=Yokoo en-aut-mei=Hidetomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=DemizuYosuke en-aut-sei=Demizu en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Division of Organic Chemistry, National Institute of Health Sciences kn-affil= affil-num=2 en-affil=Division of Organic Chemistry, National Institute of Health Sciences kn-affil= affil-num=3 en-affil=Division of Organic Chemistry, National Institute of Health Sciences kn-affil= affil-num=4 en-affil=Division of Organic Chemistry, National Institute of Health Sciences kn-affil= affil-num=5 en-affil=Division of Organic Chemistry, National Institute of Health Sciences kn-affil= affil-num=6 en-affil=Division of Organic Chemistry, National Institute of Health Sciences kn-affil= affil-num=7 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=cell-penetrating peptide kn-keyword=cell-penetrating peptide en-keyword=stapled peptide kn-keyword=stapled peptide en-keyword=hydrophobic peptide kn-keyword=hydrophobic peptide en-keyword=helical structure kn-keyword=helical structure en-keyword=plasmid DNA delivery kn-keyword=plasmid DNA delivery 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.

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=24 cd-vols= no-issue=8 article-no= start-page=7394 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230417 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Neuropilin 1 (NRP1) Positively Regulates Adipogenic Differentiation in C3H10T1/2 Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Neuropilin 1 (NRP1), a non-tyrosine kinase receptor for several ligands, is highly expressed in many kinds of mesenchymal stem cells (MSCs), but its function is poorly understood. In this study, we explored the roles of full-length NRP1 and glycosaminoglycan (GAG)-modifiable NRP1 in adipogenesis in C3H10T1/2 cells. The expression of full-length NRP1 and GAG-modifiable NRP1 increased during adipogenic differentiation in C3H10T1/2 cells. NRP1 knockdown repressed adipogenesis while decreasing the levels of Akt and ERK1/2 phosphorylation. Moreover, the scaffold protein JIP4 was involved in adipogenesis in C3H10T1/2 cells by interacting with NRP1. Furthermore, overexpression of non-GAG-modifiable NRP1 mutant (S612A) greatly promoted adipogenic differentiation, accompanied by upregulation of the phosphorylated Akt and ERK1/2. Taken together, these results indicate that NRP1 is a key regulator that promotes adipogenesis in C3H10T1/2 cells by interacting with JIP4 and activating the Akt and ERK1/2 pathway. Non-GAG-modifiable NRP1 mutant (S612A) accelerates the process of adipogenic differentiation, suggesting that GAG glycosylation is a negative post-translational modification of NRP1 in adipogenic differentiation. en-copyright= kn-copyright= en-aut-name=YuYaqiong en-aut-sei=Yu en-aut-mei=Yaqiong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Uchida-FukuharaYoko en-aut-sei=Uchida-Fukuhara en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WengYao en-aut-sei=Weng en-aut-mei=Yao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HeYuhan en-aut-sei=He en-aut-mei=Yuhan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IkegameMika en-aut-sei=Ikegame en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=YoshidaKaya en-aut-sei=Yoshida en-aut-mei=Kaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkamuraHirohiko en-aut-sei=Okamura en-aut-mei=Hirohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=QiuLihong en-aut-sei=Qiu en-aut-mei=Lihong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Endodontics, School and Hospital of Stomatology, China Medical University, Liaoning Provincial Key Laboratory of Oral Diseases kn-affil= affil-num=2 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Endodontics, School and Hospital of Stomatology, China Medical University, Liaoning Provincial Key Laboratory of Oral Diseases kn-affil= affil-num=5 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral Healthcare Education, Institute of Biomedical Sciences, Tokushima University Graduate School kn-affil= affil-num=8 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Endodontics, School and Hospital of Stomatology, China Medical University, Liaoning Provincial Key Laboratory of Oral Diseases kn-affil= en-keyword=neuropilin 1 kn-keyword=neuropilin 1 en-keyword=adipogenic differentiation kn-keyword=adipogenic differentiation en-keyword=mesenchymal stem cells kn-keyword=mesenchymal stem cells END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=6 article-no= start-page=5168 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Stress-Inducible SCAND Factors Suppress the Stress Response and Are Biomarkers for Enhanced Prognosis in Cancers en-subtitle= kn-subtitle= en-abstract= kn-abstract=The cell stress response is an essential system present in every cell for responding and adapting to environmental stimulations. A major program for stress response is the heat shock factor (HSF)-heat shock protein (HSP) system that maintains proteostasis in cells and promotes cancer progression. However, less is known about how the cell stress response is regulated by alternative transcription factors. Here, we show that the SCAN domain (SCAND)-containing transcription factors (SCAN-TFs) are involved in repressing the stress response in cancer. SCAND1 and SCAND2 are SCAND-only proteins that can hetero-oligomerize with SCAN-zinc finger transcription factors, such as MZF1(ZSCAN6), for accessing DNA and transcriptionally co-repressing target genes. We found that heat stress induced the expression of SCAND1, SCAND2, and MZF1 bound to HSP90 gene promoter regions in prostate cancer cells. Moreover, heat stress switched the transcript variants' expression from long noncoding RNA (lncRNA-SCAND2P) to protein-coding mRNA of SCAND2, potentially by regulating alternative splicing. High expression of HSP90AA1 correlated with poorer prognoses in several cancer types, although SCAND1 and MZF1 blocked the heat shock responsiveness of HSP90AA1 in prostate cancer cells. Consistent with this, gene expression of SCAND2, SCAND1, and MZF1 was negatively correlated with HSP90 gene expression in prostate adenocarcinoma. By searching databases of patient-derived tumor samples, we found that MZF1 and SCAND2 RNA were more highly expressed in normal tissues than in tumor tissues in several cancer types. Of note, high RNA expression of SCAND2, SCAND1, and MZF1 correlated with enhanced prognoses of pancreatic cancer and head and neck cancers. Additionally, high expression of SCAND2 RNA was correlated with better prognoses of lung adenocarcinoma and sarcoma. These data suggest that the stress-inducible SCAN-TFs can function as a feedback system, suppressing excessive stress response and inhibiting cancers. en-copyright= kn-copyright= en-aut-name=ShetaMona en-aut-sei=Sheta en-aut-mei=Mona kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshidaKunihiro en-aut-sei=Yoshida en-aut-mei=Kunihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanemotoHideka en-aut-sei=Kanemoto en-aut-mei=Hideka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=CalderwoodStuart K. en-aut-sei=Calderwood en-aut-mei=Stuart K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=EguchiTakanori en-aut-sei=Eguchi en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Radiation Oncology, Beth Israel Deaconess Medical Center, Harvard Medical School kn-affil= affil-num=5 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=cell stress response kn-keyword=cell stress response en-keyword=heat shock protein 90 (HSP90) kn-keyword=heat shock protein 90 (HSP90) en-keyword=SCAN domain (SCAND)-containing proteins kn-keyword=SCAN domain (SCAND)-containing proteins en-keyword=MZF1 kn-keyword=MZF1 en-keyword=ZSCAN6 kn-keyword=ZSCAN6 en-keyword=heat shock factor (HSF) kn-keyword=heat shock factor (HSF) en-keyword=long noncoding RNA (lncRNA) kn-keyword=long noncoding RNA (lncRNA) en-keyword=co-expression correlation kn-keyword=co-expression correlation en-keyword=Kaplan-Meier plot kn-keyword=Kaplan-Meier plot en-keyword=cancer patient prognosis kn-keyword=cancer patient prognosis END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=2183710 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electrochemical control of bone microstructure on electroactive surfaces for modulation of stem cells and bone tissue engineering en-subtitle= kn-subtitle= en-abstract= kn-abstract=Controlling stem cell behavior at the material interface is crucial for the development of novel technologies in stem cell biology and regenerative medicine. The composition and presentation of bio-factors on a surface strongly influence the activity of stem cells. Herein, we designed an electroactive surface that mimics the initial process of trabecular bone formation, by immobilizing chondrocyte-derived plasma membrane nanofragments (PMNFs) on its surface for rapid mineralization within 2 days. Moreover, the electroactive surface was based on the conducting polymer polypyrrole (PPy), which enabled dynamic control of the presentation of PMNFs on the surface via electrochemical redox switching, further resulting in the formation of bone minerals with different morphologies. Furthermore, bone minerals with contrasting surface morphologies had differential effects on the differentiation of human bone marrow-derived stem cells (hBMSCs) cultured on the surface. Together, this electroactive surface showed multifunctional characteristics, not only allowing dynamic control of PMNF presentation but also promoting the formation of bone minerals with different morphologies within 2 days. This electroactive substrate could be valuable for more precise control of stem cell growth and differentiation, and further development of more suitable microenvironments containing bone apatite for housing a bone marrow stem cell niche, such as biochips/bone-on-chips. en-copyright= kn-copyright= en-aut-name=CaoDanfeng en-aut-sei=Cao en-aut-mei=Danfeng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MartinezJose G. en-aut-sei=Martinez en-aut-mei=Jose G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AnadaRisa en-aut-sei=Anada en-aut-mei=Risa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=KamiokaHiroshi en-aut-sei=Kamioka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=JagerEdwin W.

Here, we investigated the effects of SPRED2 loss on hepatocellular carcinoma (HCC) cell function. Human HCC cell lines, expressing various levels of SPRED2 and SPRED2 knockdown, increased ERK1/2 activation. SPRED2-knockout (KO)-HepG2 cells displayed an elongated spindle shape with increased cell migration/invasion and cadherin switching, with features of epithelial-mesenchymal transition (EMT). SPRED2-KO cells demonstrated a higher ability to form spheres and colonies, expressed higher levels of stemness markers and were more resistant to cisplatin. Interestingly, SPRED2-KO cells also expressed higher levels of the stem cell surface markers CD44 and CD90. When CD44(+)CD90(+) and CD44(-)CD90(-) populations from WT cells were analyzed, a lower level of SPRED2 and higher levels of stem cell markers were detected in CD44(+)CD90(+) cells. Further, endogenous SPRED2 expression decreased when WT cells were cultured in 3D, but was restored in 2D culture. Finally, the levels of SPRED2 in clinical HCC tissues were significantly lower than those in adjacent non-HCC tissues and were negatively associated with progression-free survival. Thus, the downregulation of SPRED2 in HCC promotes EMT and stemness through the activation of the ERK1/2 pathway, and leads to more malignant phenotypes. en-copyright= kn-copyright= en-aut-name=GaoTong en-aut-sei=Gao en-aut-mei=Tong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YangXu en-aut-sei=Yang en-aut-mei=Xu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujisawaMasayoshi en-aut-sei=Fujisawa en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WangTianyi en-aut-sei=Wang en-aut-mei=Tianyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TomonobuNahoko en-aut-sei=Tomonobu en-aut-mei=Nahoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakaguchiMasakiyo en-aut-sei=Sakaguchi en-aut-mei=Masakiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshimuraTeizo en-aut-sei=Yoshimura en-aut-mei=Teizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Cell Biology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Cell Biology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=cancer stem cells kn-keyword=cancer stem cells en-keyword=epithelial-mesenchymal transition kn-keyword=epithelial-mesenchymal transition en-keyword=ERK1/2-MAPK kn-keyword=ERK1/2-MAPK en-keyword=tumorigenesis kn-keyword=tumorigenesis END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue= article-no= start-page=82 end-page=87 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Statistical evaluation of the effectiveness of dual amplitude-gated stereotactic body radiotherapy using fiducial markers and lung volume en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and purpose: The low tracking accuracy of lung stereotactic body radiotherapy (SBRT) risks reduced treatment efficacy. We used four-dimensional computed tomography (4DCT) images to determine the correlation between changes in fiducial marker positions and lung volume for lung tumors, and we evaluated the effectiveness of the combined use of these images in lung SBRT.
Materials and methods: Data of 30 patients who underwent fiducial marker placement were retrospectively analyzed. We calculated the motion amplitudes of the center of gravity coordinates of the lung tumor and fiducial markers in each phase and the ipsilateral, contralateral, and bilateral lung volumes using 4DCT. Moreover, we calculated the cross-correlation coefficient between the fiducial marker position and the lung volume changes waveform for the motion amplitude waveform of the lung tumor over three gating windows (all phases, ?2 mm3, and ?3 mm3).
Results: Compared with the lung volume, approximately 30 % of the fiducial markers demonstrated a low correlation with the lung tumor. In the ?2 mm3 and ?3 mm3 gating windows, the cross-correlation coefficients between the lung tumor and the optimal marker (r > 0.9: 83 % and 86 %) were significantly different for all fiducial markers (r > 0.9: 39 %, 53 %) and the ipsilateral (r > 0.9: 35 % and 40 %), contralateral (r > 0.9: 44 % and 41 %), and bilateral (r > 0.9: 39 % and 45 %) lung volumes.
Conclusions: Some of the fiducial markers showed a low correlation with the lung tumor. This study indicated that the combined use of lung volume monitoring can improve tracking accuracy. en-copyright= kn-copyright= en-aut-name=TanabeYoshinori en-aut-sei=Tanabe en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaHidekazu en-aut-sei=Tanaka en-aut-mei=Hidekazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiation Oncology, Yamaguchi University Graduate School of Medicine kn-affil= en-keyword=Fiducial marker kn-keyword=Fiducial marker en-keyword=Respiratory gating method kn-keyword=Respiratory gating method en-keyword=Stereotactic body radiotherapy kn-keyword=Stereotactic body radiotherapy en-keyword=Tumor tracking kn-keyword=Tumor tracking en-keyword=Lung cancer kn-keyword=Lung cancer en-keyword=4DCT kn-keyword=4DCT END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=3 article-no= start-page=1925 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Are Non-Invasive Modalities for the Assessment of Atherosclerosis Useful for Heart Failure Predictions? en-subtitle= kn-subtitle= en-abstract= kn-abstract=Heart failure (HF) is becoming an increasingly common issue worldwide and is associated with significant morbidity and mortality, making its prevention an important clinical goal. The criteria evaluated using non-invasive modalities such as coronary artery calcification, the ankle-brachial index, and carotid intima-media thickness have been proven to be effective in determining the relative risk of atherosclerotic cardiovascular disease. Notably, risk assessments using these modalities have been proven to be superior to the traditional risk predictors of cardiovascular disease. However, the ability to assess HF risk has not yet been well-established. In this review, we describe the clinical significance of such non-invasive modalities of atherosclerosis assessments and examine their ability to assess HF risk. The predictive value could be influenced by the left ventricular ejection fraction. Specifically, when the ejection fraction is reduced, its predictive value increases because this condition is potentially a result of coronary artery disease. In contrast, using these measures to predict HF with a preserved ejection fraction may be difficult because it is a heterogeneous condition. To overcome this issue, further research, especially on HF with a preserved ejection fraction, is required. en-copyright= kn-copyright= en-aut-name=OsawaKazuhiro en-aut-sei=Osawa en-aut-mei=Kazuhiro 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= affil-num=1 en-affil=Department of General Internal Medicine 3, Kawasaki Medical School General Medical Center kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=heart failure kn-keyword=heart failure en-keyword=coronary artery calcification kn-keyword=coronary artery calcification en-keyword=ankle-brachial index kn-keyword=ankle-brachial index en-keyword=carotid intima-media thickness kn-keyword=carotid intima-media thickness en-keyword=cardio-ankle vascular index kn-keyword=cardio-ankle vascular index END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=5 article-no= start-page=4411 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230223 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Revisiting Cryptocyanine Dye, NK-4, as an Old and New Drug: Review and Future Perspectives en-subtitle= kn-subtitle= en-abstract= kn-abstract=NK-4 plays a key role in the treatment of various diseases, such as in hay fever to expect anti-allergic effects, in bacterial infections and gum abscesses to expect anti-inflammatory effects, in scratches, cuts, and mouth sores from bites inside the mouth for enhanced wound healing, in herpes simplex virus (HSV)-1 infections for antiviral effects, and in peripheral nerve disease that causes tingling pain and numbness in hands and feet, while NK-4 is used also to expect antioxidative and neuroprotective effects. We review all therapeutic directions for the cyanine dye NK-4, as well as the pharmacological mechanism of NK-4 in animal models of related diseases. Currently, NK-4, which is sold as an over-the-counter drug in drugstores, is approved for treating allergic diseases, loss of appetite, sleepiness, anemia, peripheral neuropathy, acute suppurative diseases, wounds, heat injuries, frostbite, and tinea pedis in Japan. The therapeutic effects of NK-4’s antioxidant and neuroprotective properties in animal models are now under development, and we hope to apply these pharmacological effects of NK-4 to the treatment of more diseases. All experimental data suggest that different kinds of utility of NK-4 in the treatment of diseases can be developed based on the various pharmacological properties of NK-4. It is expected that NK-4 could be developed in more therapeutic strategies to treat many types of diseases, such as neurodegenerative and retinal degenerative diseases. en-copyright= kn-copyright= en-aut-name=LiuShihui en-aut-sei=Liu en-aut-mei=Shihui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AbeTakumi en-aut-sei=Abe en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=3 article-no= start-page=2926 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Expression of Acetabular Labral Vascular Endothelial Growth Factor and Nerve Growth Factor Is Directly Associated with Hip Osteoarthritis Pain: Investigation by Immunohistochemical Staining en-subtitle= kn-subtitle= en-abstract= kn-abstract=The acetabular labrum enhances hip joint stability and plays a key role in osteoarthritis (OA) progression. Labral nerve endings contribute to hip OA pain. Moreover, vascular endothelial growth factor (VEGF) and nerve growth factor (NGF) are associated with pain. Consequently, we analysed VEGF and NGF expression levels in the labrum and their roles in OA. Labra obtained from OA patients were stained immunohistochemically, and labral cells were cultured and subjected to a reverse transcription (RT)-polymerase chain reaction (PCR) to analyse VEGF and NGF mRNA expression. VEGF and NGF expression were compared in each region of the labrum. Correlations between VEGF and NGF expression and age, body mass index, Kellgren-Lawrence grade, Harris Hip Score, the visual analogue scale (VAS), and Krenn score were analysed, and the RT-PCR confirmed the findings. VEGF and NGF expression were high on the labral articular side, negatively correlated with the Krenn score, and positively correlated with the VAS in early OA. VEGF and NGF mRNA expression increased significantly in patients with severe pain and decreased significantly in severely degenerated labra. In early OA, VEGF and NGF expression in the acetabular labrum was associated with the occurrence of hip pain; therefore, these factors could be effective targets for pain management. en-copyright= kn-copyright= en-aut-name=SatoYoshihiro en-aut-sei=Sato en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=KawamuraYoshi en-aut-sei=Kawamura en-aut-mei=Yoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshidaAki en-aut-sei=Yoshida en-aut-mei=Aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Intelligent Orthopaedic System, Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Medical Materials for Musculoskeletal Reconstruction, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=hip osteoarthritis (OA) kn-keyword=hip osteoarthritis (OA) en-keyword=acetabular labrum kn-keyword=acetabular labrum en-keyword=vascular endothelial growth factor (VEGF) kn-keyword=vascular endothelial growth factor (VEGF) en-keyword=nerve growth factor (NGF) kn-keyword=nerve growth factor (NGF) en-keyword=immunochemical staining kn-keyword=immunochemical staining END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=3 article-no= start-page=1921 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202302 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Microcalcification and Tc-99m-Pyrophosphate Uptake without Increased Bone Metabolism in Cardiac Tissue from Patients with Transthyretin Cardiac Amyloidosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Transthyretin cardiac amyloidosis (ATTR-CA) is characterized by high Tc-99m-labeled bone tracer uptake in the heart. However, the mechanism of bone tracer uptake into the heart remains controversial. Since bone tracer uptake into metastatic bone tumors is thought to be associated with increased bone metabolism, we examined Tc-99m-pyrophosphate (PYP) scintigraphy findings, endomyocardial biopsy (EMB) tissue findings, and the expression of bone metabolism-related genes in the EMB tissues in patients with ATTR-CA, amyloid light-chain cardiac amyloidosis (AL-CA), and noncardiac amyloidosis (non-CA) in this study. The uptake of Tc-99m-PYP in the heart was significantly higher in the ATTR-CA patients than in the AL-CA and non-CA patients. A higher percentage of ATTR-CA EMB tissue showed von Kossa-positive microparticles: ATTR-CA, 62%; AL-CA, 33%; and non-CA, 0%. Calcified microparticles were identified using transmission electron microscopy. However, none of the osteogenic marker genes, osteoclastic marker genes, or phosphate/pyrophosphate-related genes were upregulated in the EMB samples from ATTR-CA patients compared to those from AL-CA and non-CA patients. These results suggest that active calcification-promoting mechanisms are not involved in the microcalcification observed in the heart in ATTR-CA. The mechanisms explaining bone tracer uptake in the heart, which is stronger than that in the ribs, require further investigation. en-copyright= kn-copyright= en-aut-name=MoriAtsushi en-aut-sei=Mori en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoYukihiro en-aut-sei=Saito en-aut-mei=Yukihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IidaToshihiro en-aut-sei=Iida en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AkagiSatoshi en-aut-sei=Akagi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshidaMasashi en-aut-sei=Yoshida en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TaniyamaMakiko en-aut-sei=Taniyama en-aut-mei=Makiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Chronic Kidney Disease and Cardiovascular Disease, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of General Medicine, Tamano Division, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=ATTR kn-keyword=ATTR en-keyword=Tc-99m-labeled bone scintigraphy kn-keyword=Tc-99m-labeled bone scintigraphy en-keyword=calcified microparticle kn-keyword=calcified microparticle END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=822 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cycloartenyl Ferulate Is the Predominant Compound in Brown Rice Conferring Cytoprotective Potential against Oxidative Stress-Induced Cytotoxicity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Since brown rice extract is a rich source of biologically active compounds, the present study is aimed to quantify the major compounds in brown rice and to compare their cytoprotective potential against oxidative stress. The content of the main hydrophobic compounds in brown rice followed the order of cycloartenyl ferulate (CAF) (89.00 +/- 8.07 nmol/g) >> alpha-tocopherol (alpha T) (19.73 +/- 2.28 nmol/g) > gamma-tocotrienol (gamma T3) (18.24 +/- 1.41 nmol/g) > alpha-tocotrienol (alpha T3) (16.02 +/- 1.29 nmol/g) > gamma-tocopherol (gamma T) (3.81 +/- 0.40 nmol/g). However, the percent contribution of CAF to the radical scavenging activity of one gram of whole brown rice was similar to those of alpha T, alpha T3, and gamma T3 because of its weaker antioxidant activity. The CAF pretreatment displayed a significant cytoprotective effect on the hydrogen peroxide-induced cytotoxicity from 10 mu M, which is lower than the minimal concentrations of alpha T and gamma T required for a significant protection. CAF also enhanced the nuclear factor erythroid 2-related factor 2 (Nrf2) nuclear translocation coincided with the enhancement of the heme oxygenase-1 (HO-1) mRNA level. An HO-1 inhibitor, tin protoporphyrin IX (SnPP), significantly impaired the cytoprotection of CAF. The cytoprotective potential of CAF is attributable to its cycloartenyl moiety besides the ferulyl moiety. These results suggested that CAF is the predominant cytoprotector in brown rice against hydrogen peroxide-induced cytotoxicity. en-copyright= kn-copyright= en-aut-name=WuHongyan en-aut-sei=Wu en-aut-mei=Hongyan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamuraToshiyuki en-aut-sei=Nakamura en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GuoYingnan en-aut-sei=Guo en-aut-mei=Yingnan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumotoRiho en-aut-sei=Matsumoto en-aut-mei=Riho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MunemasaShintaro en-aut-sei=Munemasa en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MurataYoshiyuki en-aut-sei=Murata en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraYoshimasa en-aut-sei=Nakamura en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=School of Food Science and Technology, Dalian Polytechnic University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=School of Food Science and Technology, Dalian Polytechnic 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=cycloartenyl ferulate kn-keyword=cycloartenyl ferulate en-keyword=antioxidative effect kn-keyword=antioxidative effect en-keyword=cytoprotective potential kn-keyword=cytoprotective potential en-keyword=heme oxygenase-1 kn-keyword=heme oxygenase-1 en-keyword=nuclear factor erythroid 2-related factor 2 kn-keyword=nuclear factor erythroid 2-related factor 2 END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=755 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Metformin and Its Immune-Mediated Effects in Various Diseases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Metformin has been a long-standing prescribed drug for treatment of type 2 diabetes (T2D) and its beneficial effects on virus infection, autoimmune diseases, aging and cancers are also recognized. Metformin modulates the differentiation and activation of various immune-mediated cells such as CD4+ and CD+8 T cells. The activation of adenosine 5 '-monophosphate-activated protein kinase (AMPK) and mammalian target of rapamycin complex 1 (mTORC1) pathway may be involved in this process. Recent studies using Extracellular Flux Analyzer demonstrated that metformin alters the activities of glycolysis, oxidative phosphorylation (OXPHOS), lipid oxidation, and glutaminolysis, which tightly link to the modulation of cytokine production in CD4+ and CD+8 T cells in various disease states, such as virus infection, autoimmune diseases, aging and cancers. en-copyright= kn-copyright= en-aut-name=NojimaIchiro en-aut-sei=Nojima en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, 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= en-keyword=CD8 T cells kn-keyword=CD8 T cells en-keyword=AMPK kn-keyword=AMPK en-keyword=mTORC kn-keyword=mTORC en-keyword=OXPHOS kn-keyword=OXPHOS en-keyword=autoimmune disease kn-keyword=autoimmune disease en-keyword=aging kn-keyword=aging en-keyword=cancer kn-keyword=cancer END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=裏表紙・英文目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=奥付 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=執筆者紹介 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue= article-no= start-page=39 end-page=41 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Summary of Research Activities : Okayama Administrative Law Research Group kn-title=岡山行政法実務研究会　研究会記録（第33回～第35回） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Okayama Administrative Law Research Group en-aut-sei=Okayama Administrative Law Research Group en-aut-mei= kn-aut-name=岡山行政法実務研究会 kn-aut-sei=岡山行政法実務研究会 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue= article-no= start-page=27 end-page=37 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Constitutional Theory of Public Transportation and Traffic Regulation in the Region kn-title=地域における公共交通と交通規制のあり方をめぐる憲法論～2020年司法試験論述問題・公法系第１問（憲法）を素材として～ en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=AraiMakoto en-aut-sei=Arai en-aut-mei=Makoto kn-aut-name=新井誠 kn-aut-sei=新井 kn-aut-mei=誠 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=広島大学大学院人間社会科学研究科 END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue= article-no= start-page=17 end-page=25 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Enhancing Initial Response to Expanding and Intensifying Disasters 　― Thinking about the Future Disaster Prevention System after the Heavy Rain Disaster of July 2018 ― kn-title=広域化、激甚化する災害への初動対応の充実に向けて～平成30年7月豪雨災害から今後の防災体制を考える～ en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=YoshidaKunishige en-aut-sei=Yoshida en-aut-mei=Kunishige kn-aut-name=吉田邦成 kn-aut-sei=吉田 kn-aut-mei=邦成 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=元　岡山県危機管理監 END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue= article-no= start-page=1 end-page=15 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Comment on Case ― What is the Serious Illegality ?

Cancer cells are heterogeneous, and only a few highly metastatic subclones metastasize. Although the majority of subclones may not metastasize, they could contribute by releasing factors that increase the capacity of highly metastatic cells and/or provide a favorable tumor microenvironment (TME). Here, we analyzed the interclonal communication in TNBC which leads to efficient cancer progression, particularly lung metastasis, using the polyclonal murine 4T1 BC model. Methods We isolated two 4T1 subclones, LM.4T1 and HM.4T1 cells with a low and a high metastatic potential, respectively, and examined the effects of LM.4T1 cells on the behaviors of HM.4T1 cells using the cell scratch assay, sphere-forming assay, sphere invasion assay, RT-qPCR, and western blotting in vitro. We also examined the contribution of LM.4T1 cells to the lung metastasis of HM.4T1 cells and TME in vivo. To identify a critical factor which may be responsible for the effects by LM.4T1 cells, we analyzed the data obtained from the GEO database. Results Co-injection of LM.4T1 cells significantly augmented lung metastases by HM.4T1 cells. LM.4T1-derived exosomes promoted the migration and invasion of HM.4T1 cells in vitro, and blocking the secretion of exosome abrogated their effects on HM.4T1 cells. Analyses of data obtained from the GEO database suggested that Wnt7a might be a critical factor responsible for the enhancing effects. In fact, a higher level of Wnt7a was detected in LM.4T1 cells, especially in exosomes, than in HM.4T1 cells, and deletion of Wnt7a in LM.4T1 cells significantly decreased the lung metastasis of HM.4T1 cells. Further, treatment with Wnt7a increased the spheroid formation by HM.4T1 cells via activation of the PI3K/Akt/mTOR signaling pathway. Finally, infiltration of alpha SMA-positive fibroblasts and angiogenesis was more prominent in tumors of LM.4T1 cells and deletion of Wnt7a in LM.4T1 cells markedly reduced angiogenesis. Conclusions We demonstrated, for the first time, that a low metastatic subclone can enhance lung metastasis of highly metastatic subclone via exosomal Wnt7a and propose Wnt7a as a molecular target to treat TNBC patients. en-copyright= kn-copyright= en-aut-name=LiChunning en-aut-sei=Li en-aut-mei=Chunning kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshimuraTeizo en-aut-sei=Yoshimura en-aut-mei=Teizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TianMiao en-aut-sei=Tian en-aut-mei=Miao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangYuze en-aut-sei=Wang en-aut-mei=Yuze kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KondoTakamasa en-aut-sei=Kondo en-aut-mei=Takamasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamamotoKen-Ichi en-aut-sei=Yamamoto en-aut-mei=Ken-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujisawaMasayoshi en-aut-sei=Fujisawa en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SakaguchiMasakiyo en-aut-sei=Sakaguchi en-aut-mei=Masakiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University 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= affil-num=7 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Cell Biology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Breast cancer kn-keyword=Breast cancer en-keyword=Metastasis kn-keyword=Metastasis en-keyword=Exosomes kn-keyword=Exosomes en-keyword=Epithelial mesenchymal transition kn-keyword=Epithelial mesenchymal transition en-keyword=Tumor microenvironment kn-keyword=Tumor microenvironment END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=6 article-no= start-page=780 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220531 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Transition Probability Test for an RO-Based Generator and the Relevance between the Randomness and the Number of ROs en-subtitle= kn-subtitle= en-abstract= kn-abstract=A ring oscillator is a well-known circuit used for generating random numbers, and interested readers can find many research results concerning the evaluation of the randomness with a packaged test suit. However, the authors think there is room for evaluating the unpredictability of a sequence from another viewpoint. In this paper, the authors focus on Wold's RO-based generator and propose a statistical test to numerically evaluate the randomness of the RO-based generator. The test adopts the state transition probabilities in a Markov process and is designed to check the uniformity of the probabilities based on hypothesis testing. As a result, it is found that the RO-based generator yields a biased output from the viewpoint of the transition probability if the number of ROs is small. More precisely, the transitions 01 -> 01 and 11 -> 11 happen frequently when the number l of ROs is less than or equal to 10. In this sense, l > 10 is recommended for use in any application, though a packaged test suit is passed. Thus, the authors believe that the proposed test contributes to evaluating the unpredictability of a sequence when used together with available statistical test suits, such as NIST SP800-22. en-copyright= kn-copyright= en-aut-name=KoderaYuta en-aut-sei=Kodera en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoRyoichi en-aut-sei=Sato en-aut-mei=Ryoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AliMd Arshad en-aut-sei=Ali en-aut-mei=Md Arshad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KusakaTakuya en-aut-sei=Kusaka en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NogamiYasuyuki en-aut-sei=Nogami en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=Department of Computer Science and Engineering, Hajee Mohammad Danesh Science and Technology University (HSTU) 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= en-keyword=true random number generator kn-keyword=true random number generator en-keyword=ring oscillator kn-keyword=ring oscillator en-keyword=Markov process kn-keyword=Markov process en-keyword=hypothesis testing kn-keyword=hypothesis testing END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=5 article-no= start-page=781 end-page=792 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=20160915 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Design of Function for Tracing Diffusion of Classified Information for IPC on KVM en-subtitle= kn-subtitle= en-abstract= kn-abstract=The leaking of information has increased in recent years. To address this problem, we previously proposed a function for tracing the diffusion of classified information in a guest OS using a virtual machine monitor (VMM). This function makes it possible to grasp the location of classified information and detect information leakage without modifying the source codes of the guest OS. The diffusion of classified information is caused by the file operation, child process creation, and inter-process communication (IPC). In a previous study, we implemented the proposed function for a file operation and child process creation excluding IPC using a kernel-based virtual machine (KVM). In this paper, we describe the design of the proposed function for IPC on a KVM without modifying the guest OS. The proposed function traces the local and remote IPCs inside the guest OS from the outside so as to trace the information diffusion. Because IPC with an outside computer might cause an information leakage, tracing the IPCs enables the detection of such a leakage. We also report the evaluation results including the traceability and performance of the proposed function. en-copyright= kn-copyright= en-aut-name=FujiiShota en-aut-sei=Fujii en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoMasaya en-aut-sei=Sato en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TaniguchiHideo en-aut-sei=Taniguchi en-aut-mei=Hideo 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 Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Information Leakage Prevention kn-keyword=Information Leakage Prevention en-keyword=Inter-Process Communication kn-keyword=Inter-Process Communication en-keyword=Virtualization kn-keyword=Virtualization END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=18 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211023 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis and characterization of conductive flexible cellulose carbon nanohorn sheets for human tissue applications en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Conductive sheets of cellulose and carbon nanomaterials and its human skin applications are an interesting research aspect as they have potential for applications for skin compatibility. Hence it is needed to explore the effects and shed light on these applications.
Method
To fabricate wearable, portable, flexible, lightweight, inexpensive, and biocompatible composite materials, carbon nanohorns (CNHs) and hydroxyethylcellulose (HEC) were used as precursors to prepare CNH-HEC (Cnh-cel) composite sheets. Cnh-cel sheets were prepared with different loading concentrations of CNHs (10, 20 50,100mg) in 200mg cellulose. To fabricate the bio-compatible sheets, a pristine composite of CNHs and HEC was prepared without any pretreatment of the materials.
Results
The obtained sheets possess a conductivity of 1.83x10(-10)S/m and bio-compatible with human skin. Analysis for skin-compatibility was performed for Cnh-cel sheets by h-CLAT in vitro skin sensitization tests to evaluate the activation of THP-1 cells. It was found that THP-1 cells were not activated by Cnh-cel; hence Cnh-cel is a safe biomaterial for human skin. It was also found that the composite allowed only a maximum loading of 100mg to retain the consistent geometry of free-standing sheets of <100m thickness. Since CNHs have a unique arrangement of aggregates (dahlia structure), the composite is homogeneous, as verified by transmission electron microscopy (TEM) and, scanning electron microscopy (SEM), and other functional properties investigated by Raman spectroscopy, Fourier transform infrared spectroscopy (FT-IR), conductivity measurement, tensile strength measurement, and skin sensitization.
Conclusion
It can be concluded that cellulose and CNHs sheets are conductive and compatible to human skin applications. en-copyright= kn-copyright= en-aut-name=SelvamKarthik Paneer en-aut-sei=Selvam en-aut-mei=Karthik Paneer kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NagahataTaichi en-aut-sei=Nagahata en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatoKosuke en-aut-sei=Kato en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KoreishiMayuko en-aut-sei=Koreishi en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakamuraToshiyuki en-aut-sei=Nakamura en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakamuraYoshimasa en-aut-sei=Nakamura en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishikawaTakeshi en-aut-sei=Nishikawa en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=HayashiYasuhiko en-aut-sei=Hayashi en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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 Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of 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 Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=9 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Carbon Nanohorns kn-keyword=Carbon Nanohorns en-keyword=Cellulose kn-keyword=Cellulose en-keyword=Skin sensitization kn-keyword=Skin sensitization en-keyword=Composites kn-keyword=Composites en-keyword=Bio-compatible kn-keyword=Bio-compatible END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=5 article-no= start-page=367 end-page=382 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=Mechanisms Underlying the Comorbidity of Schizophrenia and Type 2 Diabetes Mellitus en-subtitle= kn-subtitle= en-abstract= kn-abstract=The mortality rate of patients with schizophrenia is high, and life expectancy is shorter by 10 to 20 years. Metabolic abnormalities including type 2 diabetes mellitus (T2DM) are among the main reasons. The prevalence of T2DM in patients with schizophrenia may be epidemiologically frequent because antipsychotics induce weight gain as a side effect and the cognitive dysfunction of patients with schizophrenia relates to a disordered lifestyle, poor diet, and low socioeconomic status. Apart from these common risk factors and risk factors unique to schizophrenia, accumulating evidence suggests the existence of common susceptibility genes between schizophrenia and T2DM. Functional proteins translated from common genetic susceptibility genes are known to regulate neuronal development in the brain and insulin in the pancreas through several common cascades. In this review, we discuss common susceptibility genes, functional cascades, and the relationship between schizophrenia and T2DM. Many genetic and epidemiological studies have reliably associated the comorbidity of schizophrenia and T2DM, and it is probably safe to think that common cascades and mechanisms suspected from common genes' functions are related to the onset of both schizophrenia and T2DM. On the other hand, even when genetic analyses are performed on a relatively large number of comorbid patients, the results are sometimes inconsistent, and susceptibility genes may carry only a low or moderate risk. We anticipate future directions in this field. en-copyright= kn-copyright= en-aut-name=MizukiYutaka en-aut-sei=Mizuki en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakamotoShinji en-aut-sei=Sakamoto en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkahisaYuko en-aut-sei=Okahisa en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YadaYuji en-aut-sei=Yada en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HashimotoNozomu en-aut-sei=Hashimoto en-aut-mei=Nozomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakakiManabu en-aut-sei=Takaki en-aut-mei=Manabu 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=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 Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=DISC1 kn-keyword=DISC1 en-keyword=kalirin kn-keyword=kalirin en-keyword=ARHGEF11 kn-keyword=ARHGEF11 en-keyword=Akt/GSK3 beta kn-keyword=Akt/GSK3 beta en-keyword=Wnt beta-catenin kn-keyword=Wnt beta-catenin END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue= article-no= start-page=23 end-page=28 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Steep posterior slope of the medial tibial plateau is associated with ramp lesions of the medial meniscus and a concomitant anterior cruciate ligament injury en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Medial meniscus (MM) tears are associated with both acute and chronic anterior cruciate ligament (ACL) insufficiency and can lead to degenerative changes in the knee. ACL reconstruction (ACLR) combined with the meniscal repair was reported to result in decreased anterior knee joint laxity with evidence of improved patient-reported outcomes in the long term. However, a subtle tear of the MM posterior segment, also known as a ramp lesion, is difficult to detect on conventional magnetic resonance imaging (MRI) and is frequently missed in ACL-deficient knees. However, there are few studies about the associations between bone geometry and ramp lesion of the MM. This study aimed to compare sagittal medial tibial slope (MTS), medial tibial plateau depth (MTPD), and coronal tibial slope (CTS) between ACL-injured knees with and without ramp lesion of the MM. We hypothesised that patients with ramp lesion of the MM and a concomitant ACL injury have a steeper MTS and shallower MTPD than those without ramp lesion of the MM. Methods: Twenty-seven patients who underwent ACLR (group A), and 15 patients with combined MM repair (group AM) were included in the study. Anterior tibial translation (ATT) was measured under general anaesthesia just before surgery using a knee arthrometer. MRI was performed in the 10 degrees-knee-flexed position. The MTS and MTPD were measured on sagittal view, and the CTS was measured on coronal view. These parameters were compared between the groups. Differences in MRI measurements or patient demographics between the groups were evaluated using the Mann-Whitney U test. Results: No significant difference was observed in demographic data and post-operative side-to-side difference in ATT between both groups. Pre-operative ATT was significantly higher in group AM than in group A (P < 0.05), whereas post-operative ATT was similar in both groups. Further, Pre-operative ATT was significantly higher in patients with MTS >= 5.0 degrees than in those with MTS <5.0 degrees (P < 0.05). In groups A and AM, the MTS were 3.6 degrees +/- 1.8 degrees and 6.2 degrees +/- 2.9 degrees, the MTPD were 2.0 +/- 0.5 mm and 2.1 +/- 0.6 mm, and the CTS were 2.5 degrees +/- 1.8 degrees and 2.4 degrees +/- 1.6 degrees, respectively. Patients in group AM had a significantly steeper MTS compared to those in group A (P < 0.01), whereas MTPD and CTS were nearly the same in both groups. When the MTS cut-off value was set at 5.0 degrees, the sensitivity and specificity for ACL injury with concomitant ramp lesion of the MM were 0.73 and 0.76, respectively. Conclusion: A steep posterior slope of the medial tibial plateau is a risk factor for ramp lesion of the MM associated with an ACL injury. Especially in patients with MTS >= 5.0 degrees, an occult MM ramp lesion should be strongly suspected, and surgeons should prepare for MM repair in combination with ACLR. en-copyright= kn-copyright= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiranakaTakaaki en-aut-sei=Hiranaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KintakaKeisuke en-aut-sei=Kintaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KodamaYuya en-aut-sei=Kodama en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KamatsukiYusuke en-aut-sei=Kamatsuki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Anterior cruciate ligament kn-keyword=Anterior cruciate ligament en-keyword=Ramp lesion kn-keyword=Ramp lesion en-keyword=Risk factor kn-keyword=Risk factor en-keyword=Magnetic resonance imaging kn-keyword=Magnetic resonance imaging en-keyword=Proximal tibial geometry kn-keyword=Proximal tibial geometry en-keyword=Medial tibial slope kn-keyword=Medial tibial slope END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=376 end-page=382 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Swarming and mating behavior in Ephemera orientalis Mclachlan, 1875 (Ephemeroptera: Ephemeridae) with morphological analyses en-subtitle= kn-subtitle= en-abstract= kn-abstract=Swarming and mating behaviors of a mayfly species, Ephemera orientalis Mclachlan, 1875 were observed in 2015, 2016, and 2018 at a river bank of the Asahi River, Japan. Males started to make swarms between late April and middle May in 2016 and 2018. The numbers of mated pairs in a swarm correlated with the numbers of flying males in a swarm in 2016 and 2018. Swarms were formed during a limited period at dusk most probably because that interval is free from natural enemies. Males competed with each other to copulate with females in swarms. We clarified the function of the forelegs of males, which are significantly longer than those of females. Males used their forelegs to hold up a female from below. Besides forelegs, males have longer tails than females. We will discuss why sexual differences are found in these traits. Our results represent the first observation of swarm mating behavior in E. orientalis. en-copyright= kn-copyright= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugeTaichi en-aut-sei=Suge en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SuzakiShunsuke en-aut-sei=Suzaki en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanabeShintaro en-aut-sei=Tanabe en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshiharaRyo en-aut-sei=Ishihara en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsumuraKentarou en-aut-sei=Matsumura en-aut-mei=Kentarou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Aquatic insect kn-keyword=Aquatic insect en-keyword=Emergence kn-keyword=Emergence en-keyword=Copulation kn-keyword=Copulation en-keyword=Foreleg kn-keyword=Foreleg en-keyword=Mayfly kn-keyword=Mayfly en-keyword=Swarm kn-keyword=Swarm END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=13 article-no= start-page=2495 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190708 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Alpinia zerumbet (Pers.): Food and Medicinal Plant with Potential In Vitro and In Vivo Anti-Cancer Activities en-subtitle= kn-subtitle= en-abstract= kn-abstract=BACKGROUND/AIM:Plants play an important role in anti-cancer drug discovery, therefore, the current study aimed to evaluate the biological activity of Alpinia zerumbet (A. zerumbet) flowers.
METHODS:The phytochemical and biological criteria of A. zerumbet were in vitro investigated as well as in mouse xenograft model.
RESULTS:A. zerumbet extracts, specially CH2Cl2 and MeOH extracts, exhibited the highest potent anti-tumor activity against Ehrlich ascites carcinoma (EAC) cells. The most active CH2Cl2 extract was subjected to bioassay-guided fractionation leading to isolatation of the naturally occurring 5,6-dehydrokawain (DK) which was characterized by IR, MS, 1H-NMR and 13C-NMR. A. zerumbet extracts, specially MeOH and CH2Cl2 extracts, exhibited significant inhibitory activity towards tumor volume (TV). Furthermore, A. zerumbet extracts declined the high level of malonaldehyde (MDA) as well as elevated the levels of superoxide dismutase (SOD) and catalase (CAT) in liver tissue homogenate. Moreover, DK showed anti-proliferative action on different human cancer cell lines. The recorded IC50 values against breast carcinoma (MCF-7), liver carcinoma (Hep-G2) and larynx carcinoma cells (HEP-2) were 3.08, 6.8, and 8.7 ?g/mL, respectively.
CONCLUSION:Taken together, these findings open the door for further investigations in order to explore the potential medicinal properties of A. zerumbet. en-copyright= kn-copyright= en-aut-name=ZahraMaram Hussein en-aut-sei=Zahra en-aut-mei=Maram Hussein kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SalemTarek A.

Metal complexes were prepared via the reaction of isatin-N(4)anti- pyrinethiosemicarbazone ligand 1 with Cu(II), Ni(II), Co(II), Zn(II), and Fe(III) ions. The obtained metal complexes 2?12 were characterized using elemental, spectral (1H-NMR, EPR, Mass, IR, UV-Vis) and thermal (TGA) techniques, as well as magnetic moment and molar conductance measurements. In addition, their geometries were studied using EPR and UV?Vis spectroscopy. To evaluate the in vivo anti-cancer activities of these complexes, the ligand 1 and its metal complexes 2, 7 and 9 were tested against solid tumors. The solid tumors were induced by subcutaneous (SC) injection of Ehrlich ascites carcinoma (EAC) cells in mice. The impact of the selected complexes on the reduction of tumor volume was determined. Also, the expression levels of vascular endothelial growth factor (VEGF) and cysteine aspartyl-specific protease-7 (caspase-7) in tumor and liver tissues of mice bearing EAC tumor were determined. Moreover, their effects on alanine transaminase (ALT), aspartate transaminase (AST), albumin, and glucose levels were measured. The results revealed that the tested compounds, especially complex 9, reduced tumor volume, inhibited the expression of VEGF, and induced the expression of caspase-7. Additionally, they restored the levels of ALT, AST, albumin, and glucose close to their normal levels. Taken together, our newly synthesized metal complexes are promising anti-cancer agents against solid tumors induced by EAC cells as supported by the inhibition of VEGF and induction of caspase-7. en-copyright= kn-copyright= en-aut-name=El-SaiedFathy en-aut-sei=El-Saied en-aut-mei=Fathy kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=El-AaragBishoy en-aut-sei=El-Aarag en-aut-mei=Bishoy kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SalemTarek en-aut-sei=Salem en-aut-mei=Tarek kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaidGhada en-aut-sei=Said en-aut-mei=Ghada kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KhalifaShaden A.

Paraquat (PQ) is one of the most widely used herbicides, although it is extremely toxic to humans. To date, PQ poisoning has no effective treatment, and therefore the current study aimed to assess for the first time the possible effects of MEL on PQ-induced lung injuries in mice. Mice received a single intraperitoneal (IP) injection of PQ (30 mg/kg), followed by IP treatment with MEL (0.1 and 0.5 mg/kg) twice per week for four consecutive weeks. Histological alterations, oxidative stress, and apoptosis in the lungs were studied. Hematoxylin and eosin (H&E) staining indicated that MEL markedly reduced lung injuries induced by PQ. Furthermore, treatment with MEL increased superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) activity, and decreased malonaldehyde (MDA) and nitric oxide (NO) levels in lung tissue homogenates. Moreover, immunohistochemical staining showed that B-cell lymphoma-2 (Bcl-2) and survivin expressions were upregulated after MEL treatment, while Ki-67 expression was downregulated. The high dose of MEL was more effective than the low dose in all experiments. In summary, MEL efficiently reduced PQ-induced lung injuries in mice. Specific pharmacological examinations are required to determine the effectiveness of MEL in cases of human PQ poisoning. en-copyright= kn-copyright= en-aut-name=El-AaragBishoy en-aut-sei=El-Aarag en-aut-mei=Bishoy kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MagdyMohamed en-aut-sei=Magdy en-aut-mei=Mohamed kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AlAjmiMohamed F. en-aut-sei=AlAjmi en-aut-mei=Mohamed F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KhalifaShaden A.

Several studies have demonstrated that posttraumatic knee osteoarthritis progresses even after anterior cruciate ligament reconstruction. Few reports described zone-specific cartilaginous damages after anterior cruciate ligament reconstruction. This study aimed to compare the status of articular cartilage at anterior cruciate ligament reconstruction with that at second-look arthroscopy.
METHODS:
This study included 20 patients (20 knees, 10 males and 10 females, mean age 22.4 years, Body mass index 24.4 kg/m2) that underwent arthroscopic anatomic double-bundle anterior cruciate ligament reconstruction and second-look arthroscopy. Mean periods from injury to reconstruction and from reconstruction to second-look arthroscopy were 3.4 and 15.3 months, respectively. Cartilage lesions were evaluated arthroscopically in the 6 articular surfaces and 40 articular subcompartments independently, and these features were graded with the International Cartilage Repair Society articular cartilage injury classification; comparisons were made between the grades at reconstruction and at second-look arthroscopy. Furthermore, clinical outcomes were assessed at reconstruction and at second-look arthroscopy, using the Lysholm knee score, Tegner activity scale, International Knee Documentation Committee score, Knee injury and Osteoarthritis Outcome Score, side-to-side difference of the KT-2000 arthrometer, and pivot shift test.
RESULTS:
Each compartment showed a deteriorated condition at second-look arthroscopy compared with the pre-reconstruction period. A significant worsening of the articular cartilage was noted in all compartments except the lateral tibial plateau and was also observed in the central region of the medial femoral condyle and trochlea after reconstruction. However, each clinical outcome was significantly improved postoperatively.
CONCLUSIONS:
Good cartilage conditions were restored in most subcompartments at second-look arthroscopy. Furthermore, posttraumatic osteoarthritic changes in the patellofemoral and medial compartments progressed even in the early postoperative period, although good knee stability and clinical outcomes were obtained. Care is necessary regarding the progression of osteoarthritis and the appearance of knee symptoms in patients undergoing anterior cruciate ligament reconstruction. en-copyright= kn-copyright=

kn-article= en-subject= kn-subject= en-title= kn-title=Mini-open excision of osteoid osteoma using intraoperative O-arm/Stealth navigation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Although osteoid osteomas have traditionally been treated by surgical excision, radiofrequency ablation (RFA) has gained favor as a less invasive procedure. However, RFA is contraindicated for osteoid osteomas close to the skin or crucial neurovascular structures, and is not covered by national health insurance in Japan. The aim of the present study was to evaluate the efficacy of surgical excision of osteoid osteomas using intraoperative navigation.
Methods
We performed a retrospective review of five patients with osteoid osteoma who underwent a mini-open excision using O-arm/Stealth navigation at our institution. The osteoid osteomas were excised using a cannulated cutter or curetted out with the assistance of navigation.
Results
Complete excision was achieved in all patients, which was confirmed by pathological examination. The mean skin incision was 2.1 cm (range, 1.5 to 3.0 cm) and the mean duration required for setup three-dimensional image was 15 min (range, 12 to 20 min). Although the mean visual analog scale score was 7 (range, 4 to 8) before surgery, all patients experienced relief from their characteristic pain immediately after surgery, with the mean scores of 2.2 (range, 1 to 3) and 0 at 2 days and 4 weeks after surgery, respectively. There was no intra-operative complication related to the navigation and no recurrence was observed during the mean follow-up period of 25 months (range, 13 to 33 months).
Conclusions
Mini-open excision using intraoperative O-arm/Stealth navigation is a safe and accurate procedure for patients with osteoid osteoma, which could cover the limitation of RFA. en-copyright=

study is a part of the activity to develop an interdisciplinary lesson plan for high school students on the climate environment around Japan and the "seasonal feeling". This time, we focused our attention to the asymmetric seasonal march from autumn to the next spring as proposed by Kato et al. (2013). Comparison of the climate between early winter and early spring was made in the class not only on that around the Japan but also on the relation to the larger-scale systems such as the Siberian air mass, including the brief data analysis. The students also compared the detailed "seasonal feeling" between the two seasons expressed in the school songs and the Japanese classic poems called "Wa-Ka". This paper reports the contents and results of this joint activity at the two high schools. en-copyright= kn-copyright= en-aut-name=KatoKuranoshin en-aut-sei=Kato en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=1 ORCID= en-aut-name=KatoHaruko en-aut-sei=Kato en-aut-mei=Haruko kn-aut-name=加藤晴子 kn-aut-sei=加藤 kn-aut-mei=晴子 aut-affil-num=2 ORCID= en-aut-name=MiyakeShoji en-aut-sei=Miyake en-aut-mei=Shoji kn-aut-name=三宅昭二 kn-aut-sei=三宅 kn-aut-mei=昭二 aut-affil-num=3 ORCID= en-aut-name=MoriTaizo en-aut-sei=Mori en-aut-mei=Taizo kn-aut-name=森泰三 kn-aut-sei=森 kn-aut-mei=泰三 aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科（理科） affil-num=2 en-affil=Faculty of Education, Gufu Shotoku Gakuen University kn-affil=岐阜聖徳学園大学教育学部（音楽） affil-num=3 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科（理科） affil-num=4 en-affil=Okayama-Ichinomiya High School kn-affil=岡山県一宮高等学校（地理） en-keyword= Interdisciplinary activity on climate and cultural understanding education kn-keyword= Interdisciplinary activity on climate and cultural understanding education en-keyword= Climate environment around Japan kn-keyword= Climate environment around Japan en-keyword=Seasonal cycle and "seasonal feeling" kn-keyword=Seasonal cycle and "seasonal feeling" en-keyword=Asymmetric seasonal march from autumn to the next spring kn-keyword=Asymmetric seasonal march from autumn to the next spring en-keyword=ESD kn-keyword=ESD END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=1 end-page=4 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20171227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Rounded pebble of metamorphosed iron-formations from conglomerate of the Miocene deposits in Yatakayama, Kibi Plateau, Okayama Prefecture kn-title=岡山県吉備高原弥高山地域に分布する中新統礫岩から変成鉄鉱石礫の発見 en-subtitle= kn-subtitle= en-abstract= kn-abstract= The Kibi Plateau was a part of the Eurasian Continent and separated by the event of opening of Japan Sea. The rounded pebble which is considered to be continental origin was discovered. The pebble is siliceous and attracts magnets. Prepared thin-sections were observed under microscope. Selected minerals were analyzed by EPMA. The rock is composed of recrystallized quartz, magnetite, riebeckite, stilpnomelane and associated with very tiny minerals with very high relief and interference colors. The assemblage suggests that there is a possibility that the rock is a metamorphic rock of iron-formations and derived from continent. en-copyright= kn-copyright= en-aut-name=SuzukiShigeyuki

kn-abstract=　平成29年3月31日，新学習指導要領が告示された。算数科の目標は，「数学的な見方・考え方を働かせ～」の言葉から始まっている。この「数学的な見方・考え方」とは何か。算数科では算数的活動という言葉を数学的活動に変えて，充実を求めている。数学的活動は算数的活動とどう違うのか。新指導要領では「どのように学ぶか」に応えて「主体的・対話的で深い学び」による不断の授業改善を求めている。この「深い学び」とはどのような学びなのか。新しい小学校学習指導要領解説算数編では，「深い学び」の鍵として「見方・考え方」を働かせることが重要であると述べられているが，この2つはどのようにつながっているのか。「深い学び」とは，算数科の新しい数学的活動（問題解決の過程を遂行すること）の一部である。子どもが考えを振り返り「統合・発展」していく過程のことであり，そこで気付いた「数学的な見方・考え方」のよさを自覚していくことだと考える。具体的な授業場面を通して，「数学的な見方・考え方」と「深い学び」とのつながりを考察する。

本年度、2017年3月に小学校学習指導要領が、続く6月にその解説が改訂された。中でも、新たな領域「Dデータの活用」での第6学年における学習事項では、現行同様、度数分布表・柱状グラフが扱われるとはいえ、統計的な問題解決活動や結論の妥当性についての批判的な考察が取り入れられ、新たな教科書には大きな改変が見込まれる。本稿では、現行の教科書に関する分析を更に行い、また次期学習指導要領・同解説を精査し、特徴や問題点を吟味する。このことは次期教科書に求められる対応につながる考察となる。

importance in both oncological and esthetic breast surgery. The BREAST-Q is a patient-reported outcome (PRO) measure that investigates HRQOL and patient satisfaction before and after breast surgery. The aim of this study was to develop a Japanese version of the BREAST-Q including the mastectomy module, the reconstruction module, the augmentation module and the reduction/mastopexy module, and to assess the psychometric properties of the mastectomy module among Japanese women.　 METHODS:　 The Japanese version of the BREAST-Q was developed through forward translation, backward translation and patient testing. Traditional psychometric testing of the mastectomy module was administered to 45 post-mastectomy patients.　 RESULTS:　 The mastectomy, reconstruction, augmentation and reduction/mastopexy modules were formally developed into Japanese. Despite cultural difference between Japanese women and original target population, the contents were considered to be valid among Japanese woman. With the exception of the sexual well-being subscale, good reliability and validity were evident for the mastectomy module (Test-retest reliability 0.76-0.95, Chronbach's alpha coefficient 0.77-0.98).　 CONCLUSIONS:　 The BREAST-Q Japanese version is a useful PRO measure for investigating the impact of breast surgery on HRQOL and patient satisfaction. Further validation in younger Japanese women is needed to determine the usefulness of the sexual well-being subscale. en-copyright= kn-copyright= en-aut-name=SaigaMiho en-aut-sei=Saiga en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TairaNaruto en-aut-sei=Taira en-aut-mei=Naruto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KimataYoshihiro en-aut-sei=Kimata en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeSatoko en-aut-sei=Watanabe en-aut-mei=Satoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MukaiYuko en-aut-sei=Mukai en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShimozumaKojiro en-aut-sei=Shimozuma en-aut-mei=Kojiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MizooTaeko en-aut-sei=Mizoo en-aut-mei=Taeko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NogamiTomohiro en-aut-sei=Nogami en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IwamotoTakayuki en-aut-sei=Iwamoto en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MotokiTakayuki en-aut-sei=Motoki en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= en-aut-name=MatsuokaJunji en-aut-sei=Matsuoka en-aut-mei=Junji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=DoiharaHiroyoshi en-aut-sei=Doihara en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil= kn-affil= affil-num=4 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Biomedical Sciences, College of Life Sciences, Ritsumeikan University kn-affil= affil-num=7 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= en-keyword=BREAST-Q kn-keyword=BREAST-Q en-keyword=Breast cancer kn-keyword=Breast cancer en-keyword=Breast reconstruction kn-keyword=Breast reconstruction en-keyword=Health-related quality of life kn-keyword=Health-related quality of life en-keyword=Satisfaction kn-keyword=Satisfaction END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=4 article-no= start-page=593 end-page=600 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201707 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Accuracy assessment methods of tissue marker clip placement after 11-gauge vacuum-assisted stereotactic breast biopsy: comparison of measurements using direct and conventional methods en-subtitle= kn-subtitle= en-abstract= kn-abstract=BACKGROUND:　 The objective of the study was to compare direct measurement with a conventional method for evaluation of clip placement in stereotactic vacuum-assisted breast biopsy (ST-VAB) and to evaluate the accuracy of clip placement using the direct method.　 METHODS:　 Accuracy of clip placement was assessed by measuring the distance from a residual calcification of a targeted calcification clustered to a clip on a mammogram after ST-VAB. Distances in the craniocaudal (CC) and mediolateral oblique (MLO) views were measured in 28 subjects with mammograms recorded twice or more after ST-VAB. The difference in the distance between the first and second measurements was defined as the reproducibility and was compared with that from a conventional method using a mask system with overlap of transparent film on the mammogram. The 3D clip-to-calcification distance was measured using the direct method in 71 subjects.　 RESULTS:　 The reproducibility of the direct method was higher than that of the conventional method in CC and MLO views (P = 0.002, P < 0.001). The median 3D clip-to-calcification distance was 2.8 mm, with an interquartile range of 2.0-4.8 mm and a range of 1.1-36.3 mm.　 CONCLUSION:　 The direct method used in this study was more accurate than the conventional method, and gave a median 3D distance of 2.8 mm between the calcification and clip. en-copyright= kn-copyright= en-aut-name=YatakeHidetoshi en-aut-sei=Yatake en-aut-mei=Hidetoshi

mycosis fungoides en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Little is known about the immunological milieu of the skin-draining lymph nodes (LNs) in mycosis fungoides (MF). Objectives: We studied dendritic cell (DC) subsets in the dermatopathic lymphadenitis of MF patients. Methods: We immunohistochemically examined DC subsets and their distribution in 16 LN samples from 14 patients with MF (N1 LN, eight patients; N2, four; and N3, four), and we compared them with non-metastatic sentinel LNs from eight patients with melanoma. Results: The number of S-100 protein+ DCs was markedly increased in the LNs from the MF patients and the major component was DC-LAMP+ mature DCs in the outer and paracortex areas, where DC-SIGN+ immature DCs were relatively decreased in proportion. In contrast, DC-SIGN+ cells were relatively increased in proportion compared to DC-LAMP+ cells in the medulla. Although no significant difference was observed in the proportions of CD1a+ or Langerin+ DCs among the N1, N2, and N3 nodes, CD163+ M2-type macrophages were increased in number in the N2 and N3 nodes. Conclusions: Our observations indicate that mature DCs accumulate in the outer and paracortex areas in dermatopathic lymphadenitis and M2-type macrophages might increase in number during disease progression. en-copyright= kn-copyright= en-aut-name=TadaKotaro en-aut-sei=Tada en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamadaToshihisa en-aut-sei=Hamada en-aut-mei=Toshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AsagoeKenji en-aut-sei=Asagoe en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UmemuraHiroshi en-aut-sei=Umemura en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Mizuno-IkedaKazuko en-aut-sei=Mizuno-Ikeda en-aut-mei=Kazuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AoyamaYumi en-aut-sei=Aoyama en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OtsukaMasaki en-aut-sei=Otsuka en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamasakiOsamu en-aut-sei=Yamasaki en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= affil-num=1 en-affil= kn-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=2 en-affil= kn-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=3 en-affil= kn-affil=Department of Dermatology, Okayama Medical Center affil-num=4 en-affil= kn-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=5 en-affil= kn-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=6 en-affil= kn-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=7 en-affil= kn-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=8 en-affil= kn-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=9 en-affil= kn-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences en-keyword=Mycosis fungoides kn-keyword=Mycosis fungoides en-keyword=dendritic cell kn-keyword=dendritic cell en-keyword=dermatopathic lymphadenitis kn-keyword=dermatopathic lymphadenitis en-keyword=DC-LAMP kn-keyword=DC-LAMP en-keyword=DC-SIGN kn-keyword=DC-SIGN en-keyword=M2-type macrophage kn-keyword=M2-type macrophage END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=3 end-page=6 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=First Synthesis of Asperopterin A, an Isoxanthopterin Glycoside from Aspergillus Oryzae en-subtitle= kn-subtitle= en-abstract= kn-abstract=The key precursor, N-2-(N,N -dimethylaminomethylene)-6-hydroxymethyl-8-methyl-3-[2-(4-nitrophenyl)ethyl]-7-xanthopterin (16) was efficiently prepared from 2,5-diamino-6-methylamino-3H-pyrimidin-4-one (5) and ethyl 3-(tert-butyldimethylsilyloxy)-2-oxopropionate (12), followed by the protection of the pteridine ring. Glycosylation of 16 with 1-O-acetyl-2,3,5-tri-O-benzoyl-beta-D-ribofuranose (18) in the presence of tin(IV) chloride yielded the corresponding beta-D-ribofuranoside. Successive removal of the protecting groups of the resulting D-ribofuranoside provided asperopterin A (4b). en-copyright= kn-copyright= en-aut-name=HanayaTadashi en-aut-sei=Hanaya en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoHiroshi en-aut-sei=Yamamoto en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Fac Sci, Dept Chem affil-num=2 en-affil= kn-affil=Shujitsu Univ, Sch Pharm en-keyword=asperopterin kn-keyword=asperopterin en-keyword=glycosylation kn-keyword=glycosylation en-keyword=isoxanthopterin kn-keyword=isoxanthopterin en-keyword=protecting groups kn-keyword=protecting groups en-keyword=pterin glycoside kn-keyword=pterin glycoside END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=1984 dt-pub=198402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=成羽町の歴史と現在 : 岡山県成羽町 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学教育学部社会科教室内地域研究会 kn-aut-sei=岡山大学教育学部社会科教室内地域研究会 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=10 article-no= start-page=566 end-page=571 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20130710 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Vascularized peripheral nerve grafting promotes myelination of regrowing optic nerve en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated whether the use of vascularized peripheral nerve grafts on the optic nerve stump enhances axonal regeneration of retinal ganglion cells compared with isolated nonvascularized grafts. The rat median nerve was microsurgically sutured with its supplying artery and vein to the optic nerve stump. The number of retinal ganglion cells with regenerating axons was evaluated by retrograde labeling into the grafted peripheral nerve, and the myelination of the regenerating axon fibers was examined by electron microscopy. The number of retinal ganglion cells with regenerating axons was significantly higher in the vascularized graft than in the nonvascularized graft. The ratio of myelinated axon fibers was also increased in vascularized grafts. Thus, grafting with their supplying arteries and veins to an injured nerve stump represents a promising strategy to accelerate axonal regeneration from neurons of the central nervous system.

kn-subtitle= en-abstract= kn-abstract=The microfluidic sperm-sorting (MFSS) device is a promising advancement for assisted reproductive technology. Previously, poly(dimethylsiloxiane) and quartz MFSS devices were developed and used for intracytoplasmic sperm injection. However, these disposable devices were not clinically suitable for assisted reproduction, so a cyclo-olefin polymer MFSS (COP-MFSS) device was developed. By micromachining, two microfluidic channels with different heights and widths (chip A: 0.3 x 0.5 mm; chip B: 0.1 x 0.6 mm) were prepared. Sorted sperm concentrations were similar in both microfluidic channels. Linear-velocity distribution using the microfluidic channel of chip B was higher than that of chip A. Using confocal fluorescence microscopy, it was found that the highest number of motile spermatozoa swam across the laminar flow at the bottom of the microfluidic channel. The time required to swim across the laminar flow was longer at the bottom and top of the microfluidic channels than in the middle because of the low fluid velocity. These results experimentally demonstrated that the width of microfluidic channels should be increased in the region of laminar flow from the semen inlet to the outlet for unsorted spermatozoa to selectively recover spermatozoa with high linear velocity. en-copyright= kn-copyright= en-aut-name=MatsuuraKoji en-aut-sei=Matsuura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakenamiMami en-aut-sei=Takenami en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurodaYuka en-aut-sei=Kuroda en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HyakutakeToru en-aut-sei=Hyakutake en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YanaseShinichiro en-aut-sei=Yanase en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NaruseKeiji en-aut-sei=Naruse en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=Research Core for Interdisciplinary Sciences, Okayama University affil-num=2 en-affil= kn-affil=Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University affil-num=3 en-affil= kn-affil=Research Core for Interdisciplinary Sciences, Okayama University affil-num=4 en-affil= kn-affil=Faculty of Engineering, Yokohama National University affil-num=5 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=6 en-affil= kn-affil=Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University en-keyword=laminar flow kn-keyword=laminar flow en-keyword=linear velocity kn-keyword=linear velocity en-keyword=microfluidic sperm sorting kn-keyword=microfluidic sperm sorting en-keyword=motility kn-keyword=motility END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=10 article-no= start-page=1503 end-page=1528 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=2010 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of an Intelligent Chair Tool System Applying New Intelligent Pneumatic Actuators en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper develops an Intelligent Chair Tool (ICT) - a new chair-type human and machine interaction seating system powered by 36 intelligent pneumatic actuators. This tool can be used to facilitate investigation of chair shapes from spring and damping effects of seating and backrest surfaces. Each actuator used consists of five extensive elements of encoder, laser strip rod, pressure sensor, valves and PSoC microcontroller incorporated in a single device. By using the ICT, different shapes, spring and damping characteristics can be obtained to aid the design of chairs from the control inputs, i.e., position x, stiffness k(s) and viscous coefficient c. Several control algorithms are presented to realize the communication and control system, and to obtain all data in real-time. The control methodology presented contains an inner force loop and an outer position loop implemented using a unified control system. The specification, development design and experimental evaluation of the ICT control system and actuator used are presented and discussed. en-copyright= kn-copyright= en-aut-name=FaudziAhmad 'Athif Mohd en-aut-sei=Faudzi en-aut-mei=Ahmad 'Athif Mohd kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzumoriKoichi en-aut-sei=Suzumori en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WakimotoShuichi en-aut-sei=Wakimoto en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=3 en-affil= kn-affil=Research Core for Interdisciplinary Sciences, Okayama University en-keyword=Intelligent Chair Tool kn-keyword=Intelligent Chair Tool en-keyword=seating system kn-keyword=seating system en-keyword=intelligent pneumatic actuator kn-keyword=intelligent pneumatic actuator en-keyword=physical human machine interaction kn-keyword=physical human machine interaction en-keyword=control application in mechatronics kn-keyword=control application in mechatronics END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=1 end-page=10 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=201112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Necessity of Hospital Dentistry to Support Paticnts Undergoig Medical Treatment: Discussion based on a Case of Intensive lnterventions in Perioperative Management kn-title=病院医療支援を目的とした口腔の管理学および専門診療分野の必要性―周術期医療への歯科的介入を例として― en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=SogaYoshihiko en-aut-sei=Soga en-aut-mei=Yoshihiko kn-aut-name=曽我賢彦 kn-aut-sei=曽我 kn-aut-mei=賢彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学病院中央診療施設医療支援歯科治療部 en-keyword=hospital dentistry kn-keyword=hospital dentistry en-keyword=collaborative approaches kn-keyword=collaborative approaches en-keyword=perioperative management kn-keyword=perioperative management END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=5 article-no= start-page=455 end-page=465 dt-received= dt-revised= dt-accepted= dt-pub-year=1989 dt-pub=1989 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Spontaneous Cell Mediated Cytotoxicity (SCMC) against Rat Skin Epidermal Cells - Comparison of Natural Cytotoxicity Cell (NC) with Killer Cell (KC) - kn-title=ラット皮膚細胞に対する natural cytotoxicity (SCMC) の検討―natural cytotoxicity 細胞(NC)とキラー細胞(KC)との比較 en-subtitle= kn-subtitle= en-abstract= kn-abstract=We have reported that normal rat spleen cells show spontaneous cell-mediated cytotoxicity (SCMC) against rat skin epidermal cells and that the cold target inhibition assay reveals that NC and immune spleen cells belonged to different cell populations. This time, we attempted to separate NC and KC from skin allografted immune spleen cells by using Percoll sedimentation and compare their cytotoxicity with that of normal spleen cells. Normal and skin grafted immune spleen cells were fractionated by 30-50% (grading by 5%) Percoll, and each fraction was used as an effector in the (51)Cr release cytotoxicity assay with the target of allogeneic or syngeneic rat tail epidermal cells. The results were; Fr. 40% as NC and Fr. 50% as KC population. Cytotoxicity of nonadherent cells to the plastic dish and nylon wool column showed approximately the same distribution. Cold target inhibition assay was then performed with each fraction, confirming the results in our previous report. Each fraction was treated with antiasialo GM1 serum and complement and drastic elimination of the cytotoxicity was seen only in Fr. 40%. In addition, cytotoxicity of Fr. 40% and Fr. 50% of 0, 1, 2, 3, 4, 7, 10, 13 and 16th days, following the syngeneic and allogeneic skin graft, was mointored in order to determine the kinetics of NC and KC activities. en-copyright= kn-copyright= en-aut-name=FujimotoHideo en-aut-sei=Fujimoto en-aut-mei=Hideo kn-aut-name=藤本英雄 kn-aut-sei=藤本 kn-aut-mei=英雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=First Department of Surgery, Okayama University Medical School en-keyword=natural cytotoxicity cell kn-keyword=natural cytotoxicity cell en-keyword=killer cell kn-keyword=killer cell en-keyword=Percoll sedimentation kn-keyword=Percoll sedimentation END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=3 article-no= start-page=241 end-page=247 dt-received= dt-revised= dt-accepted= dt-pub-year=2007 dt-pub=200703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Alternative Leader-Exon Usage in Mouse IGF-I mRNA Variants: Class 1 and Class 2 IGF-I mRNAs en-subtitle= kn-subtitle= en-abstract= kn-abstract=The mouse IGF-I gene contains six exons, and exon 1 and exon 2 gene are considered to be leader exons. The regulatory mechanism of alternative usage of the leader exons is unclear in mice. The present study, was aimed at clarifying changes in class 1 (derived from exon 1) and class 2 (derived from exon 2) IGF-I mRNA expression in mice under various conditions. Both class 1 and class 2 IGF-I mRNAs were expressed in the mouse uterus, liver and kidney, and class 1 IGF-I mRNA was the major transcript in all organs studied. In the uterus, both class 1 and class 2 IGF-I mRNA expression changed markedly during the estrous cycle, with the highest level at proestrus, but in the liver and kidney there were no significant changes in IGF-I mRNA expression during the estrous cycle. Estrogen treatment increased both class 1 and class 2 IGF-I mRNA levels in the uterus of ovariectomized mice, but class 1 mRNA expression increased more in response to estrogen treatment than class 2 mRNA expression. These findings suggest that estrogen stimulates IGF-I gene expression in, uterine cells, and that a promoter involved in transcription of class 1 IGF-I mRNA is more responsive to estrogen. In conclusion, the present study revealed that two leader exons of mouse IGF-I gene are used in the uterus, liver and kidney. IGF-I mRNA levels of both classes changed during the estrous cycle in the uterus, but not in the liver or kidney. Estrogen increased IGF-I mRNA levels of both classes in the uterus. en-copyright= kn-copyright= en-aut-name=OhtsukiTakashi en-aut-sei=Ohtsuki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtsukiMariko en-aut-sei=Otsuki en-aut-mei=Mariko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MurakamiYousuke en-aut-sei=Murakami en-aut-mei=Yousuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HirataKensaku en-aut-sei=Hirata en-aut-mei=Kensaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakeuchiSakae en-aut-sei=Takeuchi en-aut-mei=Sakae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakahashiSumio en-aut-sei=Takahashi en-aut-mei=Sumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=Department of Biology, Faculty of Science, Okayama University affil-num=2 en-affil= kn-affil=Department of Biology, Faculty of Science, Okayama University affil-num=3 en-affil= kn-affil=Department of Biology, Faculty of Science, Okayama University affil-num=4 en-affil= kn-affil=Department of Biology, Faculty of Science, Okayama University affil-num=5 en-affil= kn-affil=Department of Biology, Faculty of Science, Okayama University affil-num=6 en-affil= kn-affil=Department of Biology, Faculty of Science, Okayama University en-keyword=IGF-I kn-keyword=IGF-I en-keyword=leader exon kn-keyword=leader exon en-keyword=estrogen kn-keyword=estrogen en-keyword=uterus kn-keyword=uterus en-keyword=mouse kn-keyword=mouse END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=6 article-no= start-page=604 end-page=610 dt-received= dt-revised= dt-accepted= dt-pub-year=2007 dt-pub=200706 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Unilateral Compound-Eye Removal on the Photoperiodic Responses of Nymphal Development in the Cricket Modicogryllus siamensis en-subtitle= kn-subtitle= en-abstract= kn-abstract=The cricket, Modicogryllus siamensis, shows clear photoperiodic responses at 25 degrees C in nymphal development. Under long-day conditions (LD16:8), nymphs became adults about 50 days after hatching, while under short-day conditions (LD8:16) the duration of nymphal stage extended to more than 130 days. Under constant dark conditions, two developmental patterns were observed: about 60% of crickets became adults slightly slower than under the long-day conditions, and the rest at later than 100 days after hatching, like those under the short-day conditions. When the compound eye was unilaterally removed on the 2nd day of hatching, an increase of molting and an extension of the nymphal period were observed under the long-day conditions, while under the short-day conditions, some crickets developed faster and others slower than intact crickets. These results suggest that this cricket receives photoperiodic information through the compound eye, that a pair of the compound eyes is required for a complete photoperiodic response, and that interaction between bilateral circadian clocks may be also involved in the response. en-copyright= kn-copyright= en-aut-name=SakamotoTomoaki en-aut-sei=Sakamoto en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TomiokaKenji en-aut-sei=Tomioka en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University en-keyword=cricket kn-keyword=cricket en-keyword=nymphal development kn-keyword=nymphal development en-keyword=photoperiodism kn-keyword=photoperiodism en-keyword=circadian clock kn-keyword=circadian clock en-keyword=compound eye kn-keyword=compound eye END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=20080321 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=津島岡大遺跡 18　―第28次調査―　（自然科学系総合研究棟新営） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岩﨑志保 kn-aut-sei=岩﨑 kn-aut-mei=志保 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=白石純 kn-aut-sei=白石 kn-aut-mei=純 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2000 dt-pub=200009 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大学埋蔵文化財調査研究センター報第24号 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学埋蔵文化財調査研究センター kn-aut-sei=岡山大学埋蔵文化財調査研究センター kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=4 article-no= start-page=245 end-page=265 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=19930325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Gerhard Schmidt, "Einf?hrung in die moderne s?chsische Verfassungsgeschichte" (VII) kn-title=ゲルハルト・シュミット「近代ザクセン国制史入門」（VII） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MatsuoNobushige en-aut-sei=Matsuo en-aut-mei=Nobushige kn-aut-name=松尾展成 kn-aut-sei=松尾 kn-aut-mei=展成 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=4 article-no= start-page=231 end-page=244 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=19930325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Haruki Kandatsu: Changes in Rural Landscapes after World War II in Japan kn-title=神立春樹著『戦後村落景観の変貌』 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=TakashigeSusumu en-aut-sei=Takashige en-aut-mei=Susumu kn-aut-name=髙重進 kn-aut-sei=髙重 kn-aut-mei=進 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=4 article-no= start-page=215 end-page=230 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=19930325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=On "The Seto Ohashi Bridge and Regional Economic Environmental Problems" edited by Prof. C.

A general survey of the spa treatment at Misasa Spa was carried out in Feburary, 1957. The informations we have gathered may be summarized as follows: 1). The number of the spa visitors seeking for curative treatment was almost equally divided between men and women and the majority of the spa visitors was over 50 years old. 2). 65% of the spa visitors came to this hot spring with the specific purpose of balneotherapy. 19.3% came for rest, 13.3% for the purpose of after-care. 3). Those who visited Misasa Spa for the first time were 44.7%, the rest being those who visited this spa over 2 times. 18.3% of them had consultation with or were under the direction of a physician. 4). The length of time they stay at this spa for curative treatment: 41.6% of the spa visitors stay for 8～14 days, 17.9% of them 15～20 days and 31% of them over three weeks. 5). About 74% of the spa visitors bathe 3 to 5 times a day for curative treatment, and 82% of them drink hot spring water. 6). Symptoms of bathing reaction such as generalised fatigue, constipation, loss of appetite, joint pain, abdominal pain and so on were observed in 50% of the spa visitors. en-copyright= kn-copyright= en-aut-name=WakutaniTohaku en-aut-sei=Wakutani en-aut-mei=Tohaku kn-aut-name=涌谷卓伯 kn-aut-sei=涌谷 kn-aut-mei=卓伯 aut-affil-num=1 ORCID= en-aut-name=MatsumotoKinshi en-aut-sei=Matsumoto en-aut-mei=Kinshi kn-aut-name=松本欣之 kn-aut-sei=松本 kn-aut-mei=欣之 aut-affil-num=2 ORCID= en-aut-name=YamamotoYasuhisa en-aut-sei=Yamamoto en-aut-mei=Yasuhisa kn-aut-name=山本泰久 kn-aut-sei=山本 kn-aut-mei=泰久 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学温泉研究所内科 affil-num=2 en-affil= kn-affil=岡山大学温泉研究所内科 affil-num=3 en-affil= kn-affil=岡山大学温泉研究所内科 END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue= article-no= start-page=54 end-page=79 dt-received= dt-revised= dt-accepted= dt-pub-year=1959 dt-pub=195901 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on Paper-analysis in the Field of Balneology. (3) The Changes of the Serum Protein Fractions and Lipoprotein Fractions Following the Bathing in Radioactive Hot Spring kn-title=温泉医学領域に於ける嘘紙分析法の研究　(III)．温泉入浴と血清蛋白分屑の変動　（付，リポ蛋白） en-subtitle= kn-subtitle= en-abstract= kn-abstract=I. Some fundamental conditions and procedures on filter-paper electrophoresis were investigated. The electrophoretic apparatus of Natsume Seisakusho and Toyo No. 51 filter-paper were used. Electrophoresis was carried out under the current of 0.25 mA/cm. in 300 Volt during 5 hours, using veronal buffer pH 8.6 (μ=0.05). In measuring of serum protein fractions, the adequate volume of the materials loaded is in the range of 0.005～0.01 ml. and in the case of lipoprotein, 0.02 ml. of serum is used. Paper-strip was stained with bromophenol blue or sudan black B, then making it transparent with heat-solved paraffin and photometered by Nataume's densitometer. The reproducibility of the above-mentioned method with a confidence of 99% was as follows: Serum protein fractions Albumin 53.4±1.8% α(1)-Globulin 3.3±0.3 α(2)-Globulin 6.0±0.5 β-Globulin 12.2±0.7 γ-Globulin 25.1±1.1 Serum lipoprotein fractions α 20.6±2.6% β+γ 79.4±2.6 II. Changes in serum protein fractions and lipoprotein fractions following the radioactive hot spring bathing were as follows: 1). In rabbits, the albumin-fraction of serum protein increased after a series of baths in radioactive hot spring, and the β- and γ-globulin-fractions decreased. 2). By cholesterol-feeding, the albumin-fraction of serum protein of rabbits decreased and the β- and γ-globulin-fractions increased significantly but when a series of baths was carried out in cholesterol-fed rabbits the decrease in the albumin-fraction was slighter than the former. 3). α-globulin-fraction of serum lipoprotein increased after single bathing in radioactive hot spring and (β+γ) -globulin-fractions showed an inverse change, but the changes of lipoprotein-fractions following a series of baths were not remarkable. 4). By cholesterol-feeding, the ratio of lipoprotein-fractions (β+γ/α) increased, but the ratio tended to decrease following a series of baths in radioactive hot spring. en-copyright= kn-copyright= en-aut-name=IshibashiMaruo en-aut-sei=Ishibashi en-aut-mei=Maruo kn-aut-name=石橋丸応 kn-aut-sei=石橋 kn-aut-mei=丸応 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学温泉研究所 END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue= article-no= start-page=29 end-page=53 dt-received= dt-revised= dt-accepted= dt-pub-year=1959 dt-pub=195901 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on Paper-analysis in the Field of Balneology. (II) 1. A New Method for the Determination of Cobalt in Blood. 2. Effects of Radioactive Thermal Bathing and Internal Use of Vitriol Water upon Cobalt Levels in Blood. kn-title=温泉医学領域に於ける濾紙分析法の研究　(II). 濾紙-Chromatographyによる血液コバルトに関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=1. A new method for the determination of cobalt in blood. The author proposed a new method for the determination of cobalt in blood by means of paper-chromatography. The procedure is follows. In a Kjeldahl colben, 5 m!. of blood is taken, and turned into wet ash with 3 ml. of HNO(3), 0.5 ml. of H(2)SO(4) and 1.5 ml. of HClO(4) and the ash aqueus solution is then neutralized with ammonium hydroxid, the neutralization being indicated by the development of color of 0.1% of p-nitrophenol (one drop) added to the solution. After addition of 2 ml. of 40% ammonium citrate, 0.5 ml. of 20% Na(2)S(2)O(3), 3～5 drops of H(2)O(2) and 1 ml. of o-nitrosoresorcine monomethyl ether (hereafter N.R.M.E.), the mixture is left for at least 15 minutes and the aqueus solution is taken in a stoppered test tube (inside diameter: 1.3 cm., hight: 16.5 cm.). The mixture is shaken with 2 ml. of carbon tetrachloride. Carbon tetrachloride is shaken with 5 ml. of 20% Na(2)CO(3) solution. Then the excess of N.R.M.E. is removed and carbon tetrachloride is concentrated on water bath to 0.3～0.5 ml. and all CCl(4) is used for a determination sample. The sample is placed on the paper (Toyo-filter paper No. 50 or 51A) in a thin line at a distance of 3 cm. from the edge, and the spot is developed with a mixture of 20 ml. of CCl(4) and 1 ml. of 90% ethylalcohoI. After development for 30～40 min., an orange-colored linear spot appears at a distance of 9～10 em. from the origin point. Spot intensity is measured at 460 mμ with Natsume's densitometer and quantitative estimation is made comparing with the standard graph. 2. Effects of radioactive thermal spring bathing and internal use of vitriol water upon cobalt levels in blood. As the author's method above-mentioned is able to determine the cobalt level in a small amount of blood, it is very convenient in investigating cobalt metabolism in the field of balneology. The author examined the changes of cobalt levels in blood after radioactive thermal bathing as well as after internal use of acid vitriol water. a. By the author's method cobalt in normal human blood was 0.4～3.6γ/100ml. in man (average: 1.6±0.4γ/100ml.) and 0.2～2.2γ/100ml. in woman (average: 0.7±0.3γ/100ml.). b. The cobalt levels in blood were measured by the author's method before and 5, 30, 60 minutes after the radioactive thermal single bathing, and before and 1, 2, 3, 4 weeks after a series of radioactive thermal baths (Rn-content: 10～30 Mache, 42～3°C., for 10 minutes). The cobalt levels in the blood of healthy subjects showed no significant change after the thermal single bathing, but those of patients with rheumatoid arthritis showed a slight increase on 3rd or 7th day and a fall on 2nd week of a series of radioactive thermal baths and then tended to return to the initial levels during the 3rd and 4th weeks of spa treatment. c. Thirty ml. of Yanahara mineral water (an acid vitriol water, pH: 2.2) was diluted with plain water to 200 ml. (Co(++)content: ca.3γ) and administered to healthy fasting subjects orally. Blood samples were taken from the cubital vein before and 1, 3, 6 hours after the intake of the vitriol water. The cobalt levels in the blood showed an increase of 14% of the initial levels at 1 and 3 hours and a decrease of 22% at 6 hours after the drinking of Yanahara mineral water. en-copyright= kn-copyright= en-aut-name=IshibashiMaruo en-aut-sei=Ishibashi en-aut-mei=Maruo kn-aut-name=石橋丸応 kn-aut-sei=石橋 kn-aut-mei=丸応 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学温泉研究所 END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue= article-no= start-page=1 end-page=28 dt-received= dt-revised= dt-accepted= dt-pub-year=1959 dt-pub=195901 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Clinical and Experimental Studies of Therapeutic Effects of Radioactive Thermal Bath on Peripheric Disorders of Circulation Part 4 Therapeutic Effects of Radioactive Thermal Bath on Blood pressure kn-title=放射能泉浴の末梢循環器病に及ぼす効果に関する臨床的並に実験的研究　第4編　三朝温泉入浴の高血圧症及び動脈硬化症に及ぼす影響に関する臨床的並びに統計的観察（血圧の変動を中心として）　付　全編の総括と結論 en-subtitle= kn-subtitle= en-abstract= kn-abstract=1) The effects of a single bath in the radioactive hot spring on the blood pressure and the pulse rate. The author observed the changes of the blood pressure and the pulse rate of subjects bathing for 20 minutes, 39°± 1°C, in temperature, in the radioactive hot spring in Misasa. It may be summerized as follows (Table 2, Fig. 1). a. In the hypertensive group (maximal blood pressure??????181 mm. Hg. and over), the maximal blood pressure had decreased immediately after bathing, and remained at this level even 2 hours after bathing. The minimal blood pressure reacted in the same manner as the maximal blood pressure. b. The moderate hypertensive group (maximal blood pressure??????180-161 mm. Hg.). In a few instances, the maximal blood pressure had increased immediately after bathing, but decreased within 30-90 minutes after bathing. Changes in the minimal blood pressure were not so remarkable. c. In the normal group (maximal blood pressure??????160～101 mm. Hg.), the maximal blood pressure had lowered within 30-90 minutes after the radioactive hot spring bathing. The minimal blood pressure showed no significant changes. b. The pulse rate had increased immediately after bathing in all groups, but within 30 minntes had returned to the initial rate and there were no further changes for 2 hours (Table 2, Fig. 2). 2) The effects of a radioactive vapour bath on the blood pressure and the pulse rate. After a bathing in vapour bath (10～15 minutes), the maximal and the minimal blood pressure showed mild decrease for 2 hours. The changes of the pulse rate and the pulse amplitude were not so remarkable (Table 3, Fig. 3). 3) The effects of a series of baths in the radioactive spring on the blood pressure. The author observed the changes in the blood pressure of the subjects bathed 2 or 3 times daily in the radioactive hot spring in Misasa, at a temperature of 42～43°C., 5～10 minutes. The blood pressure of subjects was measured once a day (at 7 a.m.) for the first week, and subsequently once weekly for two additional weeks. Subjects with an initial maximal blood pressure over 160 mm. Hg. showed a fall on the second day of the spa treatment followed by a temporary rise on the 3rd or 4th day, after which the pressure fell to the 2nd day level again, and then remained fairly constant to the end of the observation period. Subjects with an initial blood pressure under 159 mm. Hg. also showed a fall in the course of the spa treatment, but the degree of the fall was slighter than that of the former (Table 4, Fig. 4). This tendency was also observed on the out-patients (Table 5, Fig. 5). The changes of the blood pressure and pulse rate of subjects after a bath for 20 minutes, in water 39±1°C. in temperature, on the first day of the spa therapy were compared with those occuring on the 6th or 7th day, and it was observed that the patterns of the changes in blood pressure following bathing on the two days were significantly different (i.e. on the latter, so called "the initial blood pressure increase following the bathing" was not observed) (Table 6,7,8, Fig.6,7,8,9,). 4) The remote investigation on the spa visitors with hypertension and/or arteriosclerosis. The author investigated the course of patients with hypertension and/or arteriosclerosis who received the spa treatment at Misasa after returned to home. The incidence of subjects who answered as being good was 86%, and it was observed the fall of the maximal and the minimal blood pressure, especially the fall was remakable in subjects who stayed at spa about 4 weeks (Table 10, 11, 12, 13, 14, 15, Fig. 10). 5) The incidence of hypertension among the residents in the spa resort and those residing in other places. The author measured the blood presssre of the out-patients of his institute over 41 years of age from June, 1956 to May, 1957. The incidence of patients with the maximal blood pressure over 160 mm. Hg. was 16.4% in spa resort, and 25.7% in places where there are no hot springs. Using x(2)-test, the difference between the two was recognised as being significant (Table 16, 18). 6) Comparison of the mortality rate of patients with hypertension between residents in the spa resort and those residing in other places. The author examined the mortality rate of persons with hypertension in the area under the jurisdiction of the Kurayoshi Sanitary Institute, Tottori prefecture, from 1954 to 1956. The rate of mortality in the spa resort was 17.5% as compared to 21.4% in other places (Table17). en-copyright= kn-copyright= en-aut-name=MatsumotoKinshi en-aut-sei=Matsumoto en-aut-mei=Kinshi kn-aut-name=松本欣之 kn-aut-sei=松本 kn-aut-mei=欣之 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学温泉研究所 END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=1959 dt-pub=195901 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大学温泉研究所報告第24号正誤表 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Institute for Thermal Spring Research, Okayama University en-aut-sei=Institute for Thermal Spring Research, Okayama University en-aut-mei= kn-aut-name=岡山大学温泉研究所 kn-aut-sei=岡山大学温泉研究所 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=1959 dt-pub=195901 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学温泉研究所 kn-aut-sei=岡山大学温泉研究所 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=441 end-page=416 dt-received= dt-revised= dt-accepted= dt-pub-year=2006 dt-pub=20067 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Control strategy and site selection of a shunt active filter for damping of harmonic propagation in power distribution systems en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=AkagiHirofumi en-aut-sei=Akagi en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=Okayama University END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=25 end-page=35 dt-received= dt-revised= dt-accepted= dt-pub-year=1982 dt-pub=198206 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An application of certain multiplicities of C∞ map germs en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=AndoYoshifumi en-aut-sei=Ando en-aut-mei=Yoshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=Yamaguchi University END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=53 end-page=71 dt-received= dt-revised= dt-accepted= dt-pub-year=1982 dt-pub=198206 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Subgroup SU(8)/Z2 of compact simple Lie group E7 and non-compact simple Lie group E{7(7)} of type E7 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=YokotaIchiro en-aut-sei=Yokota en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=Shinshu University END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=1 end-page=6 dt-received= dt-revised= dt-accepted= dt-pub-year=1982 dt-pub=198206 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Note on groups with isomorphic group algebras en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=FurukawaT?ru en-aut-sei=Furukawa en-aut-mei=T?ru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=Okayama University END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=21 end-page=23 dt-received= dt-revised= dt-accepted= dt-pub-year=1982 dt-pub=198206 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=On a theorem of M.
