The data were analyzed using the modified grounded theory approach (M-GTA), yielding five categories: (i) Awareness of being a breast cancer patient, (ii) Being at a loss, (iii) Support from significant others, (iv) The struggle to transition from being a patient with cancer to becoming “the person I want to be”, and (v) Reaching the “me” I want to be who can face building a relationship with a partner. These findings suggest that young breast cancer patients must feel that they can lead a normal life through activities such as work or acquiring qualifications before building relationships with their partners, and that getting closer to their desired selves is important. Nurses can provide information to young patients with breast cancer to assist them in building a solid relationship with their partners. We believe that this support may enhance the patients’ quality of life and help them achieve stronger relationships with their partners. en-copyright= kn-copyright= en-aut-name=YoshikawaAyumi en-aut-sei=Yoshikawa en-aut-mei=Ayumi 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=OkanagaMayumi en-aut-sei=Okanaga en-aut-mei=Mayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoShinya en-aut-sei=Saito en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Faculty of Nursing, Osaka Dental University kn-affil= affil-num=2 en-affil=Kawasaki Medical School, Department of Breast and Thyroid Surgery kn-affil= affil-num=3 en-affil=Gifu College of Nursing, Nursing of Children and Child-Rearing Families kn-affil= affil-num=4 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=breast cancer patient kn-keyword=breast cancer patient en-keyword=young patient kn-keyword=young patient en-keyword=single kn-keyword=single en-keyword=partners kn-keyword=partners en-keyword=relationships kn-keyword=relationships END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=129 end-page=134 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Case of Retinitis Pigmentosa Diagnosed with Severe Anterior Capsule Contraction after Cataract Surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 66-year-old woman presented with significant anterior capsule contraction and intraocular lens dislocation in both eyes 4 months after cataract surgery.

Rarely, cystic swellings are neglected until adulthood, with only 14 cases of malignancy developing in an untreated meningomyelocele reported to date. We describe the case details of a 26-year-old Indian woman with this rare complication. Magnetic resonance imaging revealed a low-lying spinal cord with spinal dysraphism, cord herniation, and a cystic lesion. The biopsy confirmed a well-differentiated squamous cell carcinoma. Malignant transformation in an untreated myelomeningocele is rare, with chronic irritation and infection as proposed causes. Early biopsy and treatment are crucial for its management. en-copyright= kn-copyright= en-aut-name=GautamAbhishek en-aut-sei=Gautam en-aut-mei=Abhishek kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KenawadekarRahul en-aut-sei=Kenawadekar en-aut-mei=Rahul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HattiholiVirupaxi en-aut-sei=Hattiholi en-aut-mei=Virupaxi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MastePraful Suresh en-aut-sei=Maste en-aut-mei=Praful Suresh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Neurosurgery, Jawaharlal Nehru Medical College, KAHER kn-affil= affil-num=2 en-affil=Department of General Surgery, Jawaharlal Nehru Medical College, KAHER kn-affil= affil-num=3 en-affil=Department of Radiology, Jawaharlal Nehru Medical College, KAHER kn-affil= affil-num=4 en-affil=Department of Neurosurgery, Jawaharlal Nehru Medical College, KAHER kn-affil= en-keyword=squamous cell carcinoma kn-keyword=squamous cell carcinoma en-keyword=meningomyelocele kn-keyword=meningomyelocele en-keyword=occult spinal dysraphism kn-keyword=occult spinal dysraphism END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=65 end-page=73 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between the Pretreatment Body Mass Index and Anamorelin’s Efficacy in Patients with Cancer Cachexia: A Retrospective Cohort Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Anamorelin (ANAM) is used to treat cancer-associated cachexia, a syndrome involving muscle loss and anorexia. The timing of the initiation of ANAM treatment is crucial to its efficacy. Although the body mass index (BMI) is a diagnostic criterion for cancer cachexia, no studies have explored its association with ANAM efficacy. We conducted a single-center, retrospective cohort study to investigate the association between the pre-treatment BMI and ANAM efficacy in patients with cancer-associated cachexia (n=47). The ANAM treatment was considered effective if the patient’s appetite improved within 30 days of treatment initiation. We calculated a BMI cutoff value (19.5 kg/m2) and used it to divide the patients into high- and low-BMI groups. Their background, clinical laboratory values, cancer types, and treatment lines were investigated. Twenty (42.6%) had a high BMI (? 19.5 kg/m2) and 27 (57.4%) had a low BMI (< 19.5 kg/m2). High BMI was significantly associated with ANAM effectiveness (odds ratio 7.86, 95% confidence interval 1.99-31.00, p=0.003). Together these results indicate that it is beneficial to initiate ANAM treatment before a patient’s BMI drops below 19.5 kg/m2. Our findings will help advance cancer cachexia treatment and serve as a reference for clinicians to predict ANAM’s efficacy. en-copyright= kn-copyright= en-aut-name=MakiMasatoshi en-aut-sei=Maki en-aut-mei=Masatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakadaRyo en-aut-sei=Takada en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshigoTomoyuki en-aut-sei=Ishigo en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiwaraMiki en-aut-sei=Fujiwara en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahashiYoko en-aut-sei=Takahashi en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtsukaShinya en-aut-sei=Otsuka en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TamuraKoji en-aut-sei=Tamura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HamaokaTerutaka en-aut-sei=Hamaoka en-aut-mei=Terutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=2 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=3 en-affil=Department of Pharmacy, Sapporo Medical University Hospital kn-affil= affil-num=4 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=5 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=6 en-affil=Department of Surgery, NHO Fukuyama Medical Center kn-affil= affil-num=7 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=8 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= en-keyword=anamorelin kn-keyword=anamorelin en-keyword=cancer-associated cachexia kn-keyword=cancer-associated cachexia en-keyword=body mass index kn-keyword=body mass index en-keyword=albumin kn-keyword=albumin en-keyword=efficacy rate kn-keyword=efficacy rate END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=4 article-no= start-page=1391 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250219 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Course of General Fatigue in Patients with Post-COVID-19 Conditions Who Were Prescribed Hochuekkito: A Single-Center Exploratory Pilot Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: After the start of the COVID-19 pandemic, general fatigue in patients with long COVID and post-COVID-19 conditions (PCC) became a medical issue. Although there is a lack of evidence-based treatments, Kampo medicine (traditional Japanese medicine) has gained attention in Japan. At an outpatient clinic in Japan specializing in long COVID, 24% of all prescriptions were Kampo medicines, and 72% of Kampo medicine prescriptions were hochuekkito. However, there has been no prospective, quantitative study on the course of fatigue in patients with long COVID and PCC who were prescribed hochuekkito. The aim of this study was to clarify the course of fatigue in those patients. Methods: This study included patients aged 18 years or older with general fatigue who visited the long COVID specialized outpatient clinic at Okayama University Hospital and consented to participate after being prescribed hochuekkito. We reviewed the backgrounds of the patients, and we evaluated the patients' fatigue assessment scale in person or online. Results: Twenty patients were enrolled in this study from September to December in 2023. The average age of the patients was 42.9 years (SD: 15.8 years) and 12 patients (60%) were female. After hochuekkito administration, the fatigue assessment scale score decreased from 35.9 (SD: 5.9) at the initial visit to 31.2 (SD: 9.4) after 8 weeks, indicating a trend for improvement in fatigue (difference: 4.7; 95% CI: 0.5-8.9). Conclusions: A trend for improvement in fatigue was observed in patients with long COVID and PCC who were prescribed hochuekkito, indicating a potential benefit of hochuekkito for general fatigue in such patients. General fatigue in patients with long COVID or PCC can be classified as post-infectious fatigue syndrome and is considered a condition of qi deficiency in Kampo medicine, for which hochuekkito is appropriately indicated. en-copyright= kn-copyright= en-aut-name=TokumasuKazuki en-aut-sei=Tokumasu en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsukiNobuyoshi en-aut-sei=Matsuki en-aut-mei=Nobuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakamotoYoko en-aut-sei=Sakamoto en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UedaKeigo en-aut-sei=Ueda en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsudaYui en-aut-sei=Matsuda en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakuradaYasue en-aut-sei=Sakurada en-aut-mei=Yasue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HondaHiroyuki en-aut-sei=Honda en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=HasegawaToru en-aut-sei=Hasegawa en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TakaseRyosuke en-aut-sei=Takase en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OmuraDaisuke en-aut-sei=Omura en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 ORCID= affil-num=1 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University 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=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=13 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=fatigue assessment scale (FAS) kn-keyword=fatigue assessment scale (FAS) en-keyword= general fatigue kn-keyword= general fatigue en-keyword= hochuekkito kn-keyword= hochuekkito en-keyword= kampo medicine kn-keyword= kampo medicine en-keyword= long COVID kn-keyword= long COVID en-keyword= post-COVID-19 condition kn-keyword= post-COVID-19 condition END start-ver=1.4 cd-journal=joma no-vol=49 cd-vols= no-issue=4 article-no= start-page=563 end-page=567 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Backside Irradiation of Ultraviolet-A for Correcting Nonuniformity Error of Gafchromic XR-QA2 Films en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: Radiochromic film is used for quality assurance and quality control of X-ray equipment in the diagnostic radiology. In addition, three-dimensional dose distribution of computed tomography (CT) is measured. To correct the nonuniformity and uncertainty of radiochromic films for dose measurement of CT, the films are preirradiated ultraviolet (UV)-A rays. There is a difference in the UV protection strength of radiochromic films. A concern exists about the effects of the UV-A irradiation intensity. We thus irradiated with UV-A rays from the backsides of the films to assess if backside irradiation was possible. Materials and Methods: Gafchromic XR-QA2 and RTQA2 were used in this study. The UV-A rays were simultaneously irradiated on the front and backsides of each film for 12 h. The yellow layer of each film was scanned and imaged. The average pixel values ± standard deviations (SDs) were compared. In the statistical analysis, a paired t-test was performed. To compare, the active-layer densities engendered by the UV-A rays. Calibration curve was created with 48 h of preirradiation of UV-A. Results: The mean pixel values ± SD for Gafchromic XR-QA2 on the front and backsides were 130.776 ± 0.812 and 81.015 ± 1.128, respectively. On the other hand, the mean pixel values ± SD for Gafchromic RTQA2 on the front and backsides were 62.299 ± 1.077 and 133.761 ± 1.365, respectively. The statistical results of the paired t-test were significantly different (P < 0.01) between both films. Fitting equation of the calibration curve is shown below. y = -390.47 ± 200 + (443.45 ± 10x80).5068 ± 0.0434. Conclusion: Based on the relationship between the sensitivity of the active layer to UV-A rays and the strength of UV protection on the surface, we concluded that backside irradiation is recommended for Gafchromic XR-QA2, and frontside irradiation is recommended for Gafchromic RTQA2. en-copyright= kn-copyright= en-aut-name=TankiNobuyoshi en-aut-sei=Tanki en-aut-mei=Nobuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GotoSachiko en-aut-sei=Goto en-aut-mei=Sachiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatsudaToshizo en-aut-sei=Katsuda en-aut-mei=Toshizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GotandaRumi en-aut-sei=Gotanda en-aut-mei=Rumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GotandaTatsuhiro en-aut-sei=Gotanda en-aut-mei=Tatsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KuwanoTadao en-aut-sei=Kuwano en-aut-mei=Tadao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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 Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Medical Radiation Technology, Shizuoka College of Medicalcare Science kn-affil= affil-num=4 en-affil=Department of Radiological Technology, Faculty of Health Science and Technology, Kawasaki University of Medical Welfare kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Faculty of Health Science and Technology, Kawasaki University of Medical Welfare kn-affil= affil-num=6 en-affil=Department of Radiology, Osaka Center for Cancer and Cardiovascular Diseases Prevention kn-affil= en-keyword=Backside irradiation kn-keyword=Backside irradiation en-keyword=computed tomography kn-keyword=computed tomography en-keyword=reflective type radiochromic film kn-keyword=reflective type radiochromic film en-keyword=ultraviolet radiation kn-keyword=ultraviolet radiation END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=1 article-no= start-page=47 end-page=50 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202502 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Immediate Effects of a Single Home-based Rehabilitation Treatment on Balance Performance and Toe-Grip Strength in Elderly Subjects Continuing the Same Rehabilitation Program en-subtitle= kn-subtitle= en-abstract= kn-abstract=We assessed the immediate effects of a home-based rehabilitation (HBR) program on the balance performance and toe-grip strength of 29 older adults (mean±SD age of 75.1±9.9; 16 males, 13 females) who were participating in HBR services provided by Japan’s nursing care insurance system. Their toe-grip strength and balance performance were measured before and after the HBR program. The subjects’ toe-grip strength was significantly improved after the treatment. The subjects who had had a stroke showed a significant improvement after HBR. Contrarily, no significant difference was observed in the subjects’ functional reach results or their one-leg standing time. These results indicate that the exercise regimen provided in the HBR program led to increased excitability of motor units and immediately enhanced the subjects’ toe-grip strength. en-copyright= kn-copyright= en-aut-name=KojimaKazunori en-aut-sei=Kojima en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UjikawaTakuya en-aut-sei=Ujikawa en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OnoToshiro en-aut-sei=Ono en-aut-mei=Toshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Physical Therapy, Faculty of Health Sciences, Okayama Healthcare Professional University kn-affil= affil-num=2 en-affil=Department of Physical Therapy, Faculty of Rehabilitation, Kawasaki University of Medical Welfare kn-affil= affil-num=3 en-affil=Department of Occupational Therapy, Faculty of Health Sciences, Okayama Healthcare Professional University kn-affil= en-keyword=home-based rehabilitation kn-keyword=home-based rehabilitation en-keyword=toe-grip strength kn-keyword=toe-grip strength en-keyword=balance performance kn-keyword=balance performance END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=6 article-no= start-page=469 end-page=474 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Treatment of Tenosynovial Giant Cell Tumor of the Cervical Spine with Postoperative Anti-RANKL Antibody (Denosumab) Administration en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tenosynovial giant cell tumor (TGCT) is a fibrous histiocytic tumor originating in the synovial membrane. While cervical TGCT may not be considered a common diagnosis preoperatively because it is relatively rare, it has a high recurrence rate and should be considered. Total resection is preferable, but it can be challenging due to the risk of damaging the vertebral artery. Denosumab has shown effectiveness as a postoperative treatment for osteolytic bone lesion. Denosumab administration coupled with close follow-up might offer an effective postoperative treatment option for unresectable TGCT with bone invasion. en-copyright= kn-copyright= en-aut-name=HirataYuichi en-aut-sei=Hirata en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NagaseTakayuki en-aut-sei=Nagase en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SasadaSusumu en-aut-sei=Sasada en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AyadaYoshiyuki en-aut-sei=Ayada en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyakeHayato en-aut-sei=Miyake en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SugaharaChiaki en-aut-sei=Sugahara en-aut-mei=Chiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamamotoHidetaka en-aut-sei=Yamamoto en-aut-mei=Hidetaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OdaYoshinao en-aut-sei=Oda en-aut-mei=Yoshinao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaShota en-aut-sei=Tanaka en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pathology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Pathology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Anatomic Pathology, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=tenosynovial giant cell tumor kn-keyword=tenosynovial giant cell tumor en-keyword=bone tumor kn-keyword=bone tumor en-keyword=spine kn-keyword=spine END start-ver=1.4 cd-journal=joma no-vol=193 cd-vols= no-issue=3 article-no= start-page=2122 end-page=2140 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230720 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Calredoxin regulates the chloroplast NADPH-dependent thioredoxin reductase in Chlamydomonas reinhardtii en-subtitle= kn-subtitle= en-abstract= kn-abstract=Calredoxin (CRX) is a calcium (Ca2+)-dependent thioredoxin (TRX) in the chloroplast of Chlamydomonas (Chlamydomonas reinhardtii) with a largely unclear physiological role. We elucidated the CRX functionality by performing in-depth quantitative proteomics of wild-type cells compared with a crx insertional mutant (IMcrx), two CRISPR/Cas9 KO mutants, and CRX rescues. These analyses revealed that the chloroplast NADPH-dependent TRX reductase (NTRC) is co-regulated with CRX. Electron transfer measurements revealed that CRX inhibits NADPH-dependent reduction of oxidized chloroplast 2-Cys peroxiredoxin (PRX1) via NTRC and that the function of the NADPH-NTRC complex is under strict control of CRX. Via non-reducing SDS-PAGE assays and mass spectrometry, our data also demonstrated that PRX1 is more oxidized under high light (HL) conditions in the absence of CRX. The redox tuning of PRX1 and control of the NADPH-NTRC complex via CRX interconnect redox control with active photosynthetic electron transport and metabolism, as well as Ca2+ signaling. In this way, an economic use of NADPH for PRX1 reduction is ensured. The finding that the absence of CRX under HL conditions severely inhibited light-driven CO2 fixation underpins the importance of CRX for redox tuning, as well as for efficient photosynthesis. en-copyright= kn-copyright= en-aut-name=ZinziusKaren en-aut-sei=Zinzius en-aut-mei=Karen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MarchettiGiulia Maria en-aut-sei=Marchetti en-aut-mei=Giulia Maria kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FischerRonja en-aut-sei=Fischer en-aut-mei=Ronja kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MilradYuval en-aut-sei=Milrad en-aut-mei=Yuval kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OltmannsAnne en-aut-sei=Oltmanns en-aut-mei=Anne kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KelterbornSimon en-aut-sei=Kelterborn en-aut-mei=Simon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YacobyIftach en-aut-sei=Yacoby en-aut-mei=Iftach kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HegemannPeter en-aut-sei=Hegemann en-aut-mei=Peter kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ScholzMartin en-aut-sei=Scholz en-aut-mei=Martin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HipplerMichael en-aut-sei=Hippler en-aut-mei=Michael kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Institute of Plant Biology and Biotechnology, University of M?nster kn-affil= affil-num=2 en-affil=Institute of Plant Biology and Biotechnology, University of M?nster kn-affil= affil-num=3 en-affil=Institute of Plant Biology and Biotechnology, University of M?nster kn-affil= affil-num=4 en-affil=School of Plant Sciences and Food Security, The George S.

Given advancements in artificial intelligence (AI) technology, its application in the medical field is expanding. However, reports on its application in medical interviews in medical education are scarce.
Objective: This study aimed to investigate whether medical students' interview skills could be improved by engaging with Al-simulated patients using large language models, including the provision of feedback.
Methods: This nonrandomized controlled trial was conducted with fourth-year medical students in Japan. A simulation program using large language models was provided to 35 students in the intervention group in 2023, while 110 students from 2022 who did not participate in the intervention were selected as the control group. The primary outcome was the score on the Pre-Clinical Clerkship Objective Structured Clinical Examination (pre-CC OSCE), a national standardized clinical skills examination, in medical interviewing. Secondary outcomes included surveys such as the Simulation-Based Training Quality Assurance Tool (SBT-QA10), administered at the start and end of the study.
Results: The Al intervention group showed significantly higher scores on medical interviews than the control group (Al group vs control group: mean 28.1, SD 1.6 vs 27.1, SD 2.2; P=.01). There was a trend of inverse correlation between the SBT-QA10 and pre-CC OSCE scores (regression coefficient-2.0 to-2.1). No significant safety concerns were observed.
Conclusions: Education through medical interviews using Al-simulated patients has demonstrated safety and a certain level of educational effectiveness. However, at present, the educational effects of this platform on nonverbal communication skills are limited, suggesting that it should be used as a supplementary tool to traditional simulation education. en-copyright= kn-copyright= en-aut-name=YamamotoAkira en-aut-sei=Yamamoto en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KodaMasahide en-aut-sei=Koda en-aut-mei=Masahide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OgawaHiroko en-aut-sei=Ogawa en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=InoHideo en-aut-sei=Ino en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Co-learning Community Healthcare Re-innovation Office, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Primary Care and Medical Education, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine 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 Hematology and Oncology, Okayama University Hospital 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=Center for Education in Medicine and Health Sciences, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=medical interview kn-keyword=medical interview en-keyword=generative pretrained transformer kn-keyword=generative pretrained transformer en-keyword=large language model kn-keyword=large language model en-keyword=simulation-based learning kn-keyword=simulation-based learning en-keyword=OSCE kn-keyword=OSCE en-keyword=artificial intelligence kn-keyword=artificial intelligence en-keyword=medical education kn-keyword=medical education en-keyword=simulated patients kn-keyword=simulated patients en-keyword=nonrandomized controlled trial kn-keyword=nonrandomized controlled trial END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=10 article-no= start-page=e087657 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241008 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Decline in and recovery of fertility rates after COVID-19-related state of emergency in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction The COVID-19 pandemic led to a decline in fertility rates worldwide. Although many regions have experienced a temporary drop in fertility rates with the spread of the infection, subsequent recovery has varied across countries. This study aimed to evaluate the impact of COVID-19 infection rates and regional sociodemographic factors on the recovery of fertility rates in Japan following the state of emergency.
Methods This study examined prefectural fertility data from before the COVID-19 pandemic to forecast fertility rates up to 2022 using a seasonal autoregressive integrated moving average model. A regression analysis was conducted on fertility rates during the first state of emergency and the subsequent recovery rate with respect to the number of new COVID-19 cases and sociodemographic factors specific to each prefecture.
Results During the first state of emergency, the monthly fertility rate decreased by an average of -13.8% (SD: 6.26, min: -28.78, max: 0.15) compared with the previous year. Over the following 22 months, the average fertility recovery rate was +2.31% (SD: 3.57; min: -8.55, max: 19.54). Multivariate analysis of the impact of the pandemic on fertility changes during the first emergency indicated a negative correlation between new COVID-19 cases per capita and the proportion of nuclear households. No significant correlation was found between fertility recovery rate and new COVID-19 cases or emergency duration. When classifying fertility rate fluctuation patterns before and after the emergency into four clusters, variations were noted in the proportion of the elderly population, marriage divorce rate and the number of internet searches related to pregnancy intentions across the clusters.
Conclusions No association was found between pregnancy intentions related to the spread of infection, such as the number of new cases and the fertility recovery rate following the first state of emergency. Differences in the patterns of decline and recovery during the pandemic were observed based on population composition and internet searches for infection and pregnancy across different prefectures. en-copyright= kn-copyright= en-aut-name=MitomaTomohiro en-aut-sei=Mitoma en-aut-mei=Tomohiro 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=OobaHikaru en-aut-sei=Ooba en-aut-mei=Hikaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= affil-num=1 en-affil=Department of Obstetric and Gynecology, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Obstetric and Gynecology, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Obstetric and Gynecology, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Obstetric and Gynecology, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=19 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240929 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Assessment of the renal function of patients with anorexia nervosa en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background A decreased glomerular filtration rate (GFR), estimated using creatinine (Cr- eGFR), is often found at the initial presentation of anorexia nervosa (AN). Its pathophysiology has been explained mainly by dehydration, and chronic hypokalemia is also thought to be a cause. However, because we have often experienced cases of AN with decreased Cr-eGFR without these conditions, we must consider different etiologies. The focus of this paper is on low free triiodothyronine (FT3) syndrome. We also discuss the utility of eGFR, estimated using cystatin-C (CysC-eGFR), for these patients.
Methods The data of 39 patients diagnosed with AN between January 2005 and December 2023 was available for study. The characteristics of patients at the lowest and highest body mass index standard deviation score (BMI-SDS) were examined. Data on the parameters Cr-eGFR, CysC-eGFR, dehydration markers, potassium (K), and hormonal data and BMI-SDS were assessed during the treatment course to evaluate the correlations in these parameters. Blood hematocrit, uric acid (UA), blood urine nitrogen (BUN) level, and urine specific gravity were adopted as dehydration markers; FT3, free thyroxine, thyroid stimulating hormone, and insulin-like growth factor were adopted as hormonal data. Cr-eGFR and simultaneously evaluated dehydration markers, K, or hormonal data were extracted and correlations associated with the changes in BMI-SDS were examined. Furthermore, Cr-eGFR and simultaneously assessed CysC-eGFR were compared.
Results When the BMI-SDS was at the lowest value, low-FT3 syndrome was shown. Severe hypokalemia was not found in our study. A linear relation was not found between Cr-eGFR and BMI-SDS. A statistically significant correlation was found between Cr-eGFR and FT3 (p = 0.0025). Among the dehydration markers, statistically significant correlations were found between Cr-eGFR and BUN or UA. The difference between Cr-eGFR and CysC-eGFR was prominent, and CysC-eGFR showed much higher values.
Conclusions Our data indicates that low-FT3 syndrome and dehydration were related to the renal function of our patients with AN. Furthermore, our data suggest that caution is needed in the interpretation of kidney function evaluation when using CysC-eGFR in cases of AN. en-copyright= kn-copyright= en-aut-name=MiyaharaHiroyuki en-aut-sei=Miyahara en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShigeyasuYoshie en-aut-sei=Shigeyasu en-aut-mei=Yoshie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiChikako en-aut-sei=Fujii en-aut-mei=Chikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaChie en-aut-sei=Tanaka en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ManaHanzawa en-aut-sei=Mana en-aut-mei=Hanzawa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SugiharaAkiko en-aut-sei=Sugihara en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkadaAyumi en-aut-sei=Okada en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Department of Clinical Pediatrics, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=6 en-affil=Clinical Psychology Section, Department of Medical Support, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Pediatrics, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Anorexia nervosa kn-keyword=Anorexia nervosa en-keyword=Dehydration kn-keyword=Dehydration en-keyword=Glomerular filtration rate estimated using creatinine kn-keyword=Glomerular filtration rate estimated using creatinine en-keyword=Glomerular filtration rate estimated using cystatin-C kn-keyword=Glomerular filtration rate estimated using cystatin-C en-keyword=Hypokalemia kn-keyword=Hypokalemia en-keyword=Low free triiodothyronine syndrome kn-keyword=Low free triiodothyronine syndrome END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=4 article-no= start-page=583 end-page=595 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231204 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Estimation of the Effects of Achilles Tendon Geometry on the Magnitude and Distribution of Local Strain: A Finite Element Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated the influence of Achilles tendon (AT) geometry on local-strain magnitude and distribution during loading, using finite element analysis. We calculated the following eight AT parameters for 18 healthy men: thickness and width of the most distal part, minimum cross-sectional area (mCSA), and most proximal part; length; and position of the mCSA. To investigate the effect of AT geometry on the magnitude and distribution of local strain, we created three-dimensional numerical models by changing the AT parameter values for every one standard deviation (SD) in the range of ±2 SD. A 4000 N lengthening force was applied to the proximal surface of all the models. The mean first principal strain (FPS) was determined every 3% of the length. The highest FPS in each model was mainly observed in the proximal regions; the 86?89% site (the most proximal site was set at 100%) had the highest number of models with the highest FPS (nine models). The highest FPS was observed in the model with a distal thickness of ?2 SD, which was 27.1% higher than that of the standard model observed in the 2?5% site. Therefore, the AT geometry influences local-strain magnitude and distribution during loading. en-copyright= kn-copyright= en-aut-name=EnomotoShota en-aut-sei=Enomoto en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OdaToshiaki en-aut-sei=Oda en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Institute for Promotion of Education and Campus Life, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Education, Hyogo University of Teacher Education kn-affil= en-keyword=computational model kn-keyword=computational model en-keyword=Mooney-Rivlin model kn-keyword=Mooney-Rivlin model en-keyword=soft tissue kn-keyword=soft tissue END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue=11 article-no= start-page=1596 end-page=1601 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Investigation of the Expression of Serine Protease in Vibrio vulnificus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vibrio vulnificus is a Gram-negative estuarine bacterium that causes infection in immuno-compromised patients, eels, and shrimp. V. vulnificus NCIMB2137, a metalloprotease-negative strain isolated from a diseased eel, produces a 45-kDa chymotrypsin-like alkaline serine protease known as VvsA. The gene encoding vvsA also includes another gene, vvsB with an unknown function; however, it is assumed to be an essential molecular chaperone for the maturation of VvsA. In the present study, we used an in vitro cell-free translation system to examine the maturation pathway of VvsA. We individually expressed the vvsA and vvsB genes and detected their mRNAs. However, the sample produced from vvsA did not exhibit protease activity. A sodium dodecyl sulfate (SDS) analysis detected the VvsB protein, but not the VvsA protein. A Western blotting analysis using a histidine (His)-tag at the amino terminus of proteins also showed no protein production by vvsA. These results suggested the translation, but not the transcription of vvsA. Factors derived from Escherichia coli were used in the in vitro cell-free translation system employed in the present study. The operon of the serine protease gene containing vvsA and vvsB was expressed in E. coli. Although serine proteases were produced, they were cleaved at different sites and no active mature forms were detected. These results indicate that the operon encoding vvsA and vvsB is a gene constructed to be specifically expressed in V. vulnificus. en-copyright= kn-copyright= en-aut-name=KawaseTomoka en-aut-sei=Kawase en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DebnathAnusuya en-aut-sei=Debnath en-aut-mei=Anusuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MizunoTamaki en-aut-sei=Mizuno en-aut-mei=Tamaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyakeYui en-aut-sei=Miyake en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Vibrio vulnificus serine protease kn-keyword=Vibrio vulnificus serine protease en-keyword=intermolecular chaperone kn-keyword=intermolecular chaperone en-keyword=cell-free translation system kn-keyword=cell-free translation system END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=14 article-no= start-page=4099 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240713 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Importance of Blood Glucose Measurement for Predicting the Prognosis of Long COVID: A Retrospective Study in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: The present study aimed to clarify the effects of a hyperglycemic condition on the clinical consequences of long COVID. Methods: Among 643 patients who visited the outpatient clinic of our hospital from February 2021 to September 2023, long COVID patients were classified into a hyperglycemic (HG) group with casual blood glucose levels above 140 mg/dL and a normoglycemic (NG) group. The patients' backgrounds, clinical symptoms, health status including the QOL evaluation scale (EQ-5D-5L), self-rating depression scale (SDS), and F-scale questionnaire (FSSG), blood test data, and recovery periods were analyzed. Results: The NG group included 607 patients with long COVID and the HG group included 36 patients with long COVID. Patients in the HG group were older than those in the NG group (55 vs. 41 years; p < 0.001) and included a larger percentage of males (67% vs. 44%; p = 0.009). The HG group had a larger percentage of patients with moderate-to-severe conditions in the acute infection phase (28% vs. 12%; p = 0.008), a higher BMI (25 vs. 22 kg/m(2); p < 0.001), higher blood pressure (138/81 vs. 122/72 mmHg; p < 0.001), and a larger percentage of patients with an alcohol drinking habit (53% vs. 34%; p = 0.031). Long COVID symptoms and self-rated scales were not differed between the two groups; however, the laboratory data showed that liver and renal functions and metabolic data were significantly worse in the HG group. Although there was no apparent difference between the two groups in duration from the infection to the first visit, the HG group had a significantly longer period of recovery from long COVID (median period of 421 vs. 294 days; p = 0.019). Conclusion: A hyperglycemic state associated with other lifestyle-related diseases is associated with the prolongation of recovery from long COVID. en-copyright= kn-copyright= en-aut-name=YokoyamaSho

kn-subtitle= en-abstract= kn-abstract=Background:Vibrio vulnificus NCIMB2137, a Gram-negative, metalloprotease negative estuarine strain was isolated from a diseased eel. A 45 kDa chymotrypsin-like alkaline serine protease known as VvsA has been recently reported as one of the major virulence factor responsible for the pathogenesis of this strain. The vvsA gene along with a downstream gene vvsB, whose function is still unknown constitute an operon designated as vvsAB. Objective: This study examines the contribution of VvsB to the functionality of VvsA. Method: In this study, VvsB was individually expressed using Rapid Translation System (RTS system), followed by an analysis of its role in regulating the serine protease activity of VvsA. Result: The proteolytic activity of VvsA increased upon the addition of purified VvsB to the culture supernatant of V. vulnificus. However, the attempts of protein expression using an E. coli system revealed a noteworthy observation that protein expression from the vvsA gene exhibited higher protease activity compared to that from the vvsAB gene within the cytoplasmic fraction. These findings suggest an intricate interplay between VvsB and VvsA, where VvsB potentially interacts with VvsA inside the bacterium and suppress the proteolytic activity. While outside the bacterial milieu, VvsB appears to stimulate the activation of inactive VvsA. Conclusion: The findings suggest that Vibrio vulnificus regulates VvsA activity through the action of VvsB, both intracellularly and extracellularly, to ensure its survival. en-copyright= kn-copyright= en-aut-name=KawaseTomoka en-aut-sei=Kawase en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DebnathAnusuya en-aut-sei=Debnath en-aut-mei=Anusuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkamotoKeinosuke en-aut-sei=Okamoto en-aut-mei=Keinosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Biotechnology, Brainware University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=RTS system kn-keyword=RTS system en-keyword=in vitro cell-free translation system, PU kn-keyword=in vitro cell-free translation system, PU en-keyword=Proteinase unit, VvsA kn-keyword=Proteinase unit, VvsA en-keyword=Vibrio vulnificus serine protease, SD kn-keyword=Vibrio vulnificus serine protease, SD en-keyword=Shine-Dalgarno sequence kn-keyword=Shine-Dalgarno sequence END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=3 article-no= start-page=301 end-page=306 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202406 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Palliative Gamma Knife Radiosurgery for a Small Part of a Large Vestibular Schwannoma in an Elderly Patient en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a case of a large vestibular schwannoma in an 80-year-old female patient that shrank after palliative Gamma Knife radiosurgery (GKS). Neurological symptoms included hearing deterioration and facial palsy. The tumor volume was 21.9 mL. Craniotomy was considered high-risk, and conventional GKS was risky, owing to the risk of transient enlargement. Therefore, GKS was performed on only a portion of the tumor. The marginal dose (12 Gy) volume was 3.8 mL (17.4%). The tumor began to shrink after transient enlargement. Sixty months later, the tumor volume was only 3.1 mL, and the patient was able to maintain independent activities of daily living without salvage treatment. en-copyright= kn-copyright= en-aut-name=NakazakiKiyoshi en-aut-sei=Nakazaki en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiraiSatoshi en-aut-sei=Hirai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HishikawaTomohito en-aut-sei=Hishikawa en-aut-mei=Tomohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Neurosurgery, Brain Attack Center Ota Memorial Hospital kn-affil= affil-num=2 en-affil=Department of Neurosurgery, Kawasaki Medical School kn-affil= affil-num=3 en-affil=Department of Neurosurgery, Kawasaki Medical School kn-affil= en-keyword=vestibular schwannoma kn-keyword=vestibular schwannoma en-keyword=Gamma Knife radiosurgery kn-keyword=Gamma Knife radiosurgery en-keyword=large volume kn-keyword=large volume en-keyword=palliative kn-keyword=palliative en-keyword=elderly patient kn-keyword=elderly patient END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=4 article-no= start-page=497 end-page=505 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=Investigation of uncertainty in internal target volume definition for lung stereotactic body radiotherapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study evaluated the validity of internal target volumes (ITVs) defined by three- (3DCT) and four-dimensional computed tomography (4DCT), and subsequently compared them with actual movements during treatment. Five patients with upper lobe lung tumors were treated with stereotactic body radiotherapy (SBRT) at 48 Gy in four fractions. Planning 3DCT images were acquired with peak-exhale and peak-inhale breath-holds, and 4DCT images were acquired in the cine mode under free breathing. Cine images were acquired using an electronic portal imaging device during irradiation. Tumor coverage was evaluated based on the manner in which the peak-to-peak breathing amplitude on the planning CT covered the range of tumor motion (±?3 SD) during irradiation in the left?right, anteroposterior, and cranio-caudal (CC) directions. The mean tumor coverage of the 4DCT-based ITV was better than that of the 3DCT-based ITV in the CC direction. The internal margin should be considered when setting the irradiation field for 4DCT. The proposed 4DCT-based ITV can be used as an efficient approach in free-breathing SBRT for upper-lobe tumors of the lung because its coverage is superior to that of 3DCT. en-copyright= kn-copyright= en-aut-name=NakanishiDaiki en-aut-sei=Nakanishi en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OitaMasataka en-aut-sei=Oita en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukunagaJun-Ichi en-aut-sei=Fukunaga en-aut-mei=Jun-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiroseTaka-Aki en-aut-sei=Hirose en-aut-mei=Taka-Aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshitakeTadamasa en-aut-sei=Yoshitake en-aut-mei=Tadamasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SasakiMotoharu en-aut-sei=Sasaki en-aut-mei=Motoharu 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=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Division of Radiology, Department of Medical Technology, Kyushu University Hospital kn-affil= affil-num=4 en-affil=Division of Radiology, Department of Medical Technology, Kyushu University Hospital kn-affil= affil-num=5 en-affil=Department of Clinical Radiology, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=6 en-affil=Graduate School of Biomedical Sciences, Tokushima University kn-affil= en-keyword=4DCT kn-keyword=4DCT en-keyword=3DCT kn-keyword=3DCT en-keyword=Internal target volume kn-keyword=Internal target volume en-keyword=EPID imaging kn-keyword=EPID imaging en-keyword=Stereotactic body radiotherapy kn-keyword=Stereotactic body radiotherapy en-keyword=Lung cancer kn-keyword=Lung cancer END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=151 end-page=161 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=p53-Armed Oncolytic Virotherapy Improves Radiosensitivity in Soft-Tissue Sarcoma by Suppressing BCL-xL Expression en-subtitle= kn-subtitle= en-abstract= kn-abstract=Soft-tissue sarcoma (STS) is a heterogeneous group of rare tumors originating predominantly from the embryonic mesoderm. Despite the development of combined modalities including radiotherapy, STSs are often refractory to antitumor modalities, and novel strategies that improve the prognosis of STS patients are needed. We previously demonstrated the therapeutic potential of two telomerase-specific replication-competent oncolytic adenoviruses, OBP-301 and tumor suppressor p53-armed OBP-702, in human STS cells. Here, we demonstrate in vitro and in vivo antitumor effects of OBP-702 in combination with ionizing radiation against human STS cells (HT1080, NMS-2, SYO-1). OBP-702 synergistically promoted the antitumor effect of ionizing radiation in the STS cells by suppressing the expression of B-cell lymphoma-X large (BCL-xL) and enhancing ionizing radiation-induced apoptosis. The in vivo experiments demonstrated that this combination therapy significantly suppressed STS tumors’ growth. Our results suggest that OBP-702 is a promising antitumor reagent for promoting the radiosensitivity of STS tumors. en-copyright= kn-copyright= en-aut-name=KomatsubaraTadashi en-aut-sei=Komatsubara en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TazawaHiroshi en-aut-sei=Tazawa en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaseiJoe en-aut-sei=Hasei en-aut-mei=Joe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OmoriToshinori en-aut-sei=Omori en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugiuKazuhisa en-aut-sei=Sugiu en-aut-mei=Kazuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MochizukiYusuke en-aut-sei=Mochizuki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=DemiyaKoji en-aut-sei=Demiya en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 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=10 ORCID= en-aut-name=UrataYasuo en-aut-sei=Urata en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KagawaShunsuke en-aut-sei=Kagawa en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 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 Gastroenterological 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= affil-num=11 en-affil=Oncolys BioPharma, Inc. kn-affil= affil-num=12 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=soft-tissue sarcoma kn-keyword=soft-tissue sarcoma en-keyword=radiotherapy kn-keyword=radiotherapy en-keyword=oncolytic adenovirus kn-keyword=oncolytic adenovirus en-keyword=p53 kn-keyword=p53 en-keyword=BCL-xL kn-keyword=BCL-xL END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=135 end-page=142 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photon-Counting Detector CT: Potential for 75% Reduction in Contrast Medium Amount: A Phantom Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to evaluate the potential reduction in contrast medium utilization using photon-counting detector computed tomography (PCD-CT). One PCD-CT scan (CT1) and three conventional (non-PCD-CT) CT scans (CT2-CT4) were performed using a multi-energy CT phantom that contained eight rods with different iodine concentrations (0.2, 0.5, 1, 2, 5, 10, 15, and 20 mg/ml). The CT values of the seven groups (CT1 for 40, 50, 60, and 70 keV; and CT2-4) were measured. Noise and contrast-to-noise ratio (CNR) were assessed for the eight rods at various iodine concentrations. CT2 and CT1 (40 keV) respectively required 20 mg/ml and 5 mg/ml of iodine, indicating that a comparable contrast effect could be obtained with approximately one-fourth of the contrast medium amount. The standard deviation values increased at lower energy levels irrespective of the iodine concentration. The CNR exhibited a decreasing trend with lower iodine concentrations, while it remained relatively stable across all iodine levels (40-70 keV). This study demonstrated that virtual monochromatic 40 keV images offer a similar contrast effect with a reduced contrast medium amount when compared to conventional CT systems at 120 kV. en-copyright= kn-copyright= en-aut-name=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorimitsuYusuke en-aut-sei=Morimitsu en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoHayato en-aut-sei=Saito en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakakiHaruhiko en-aut-sei=Takaki en-aut-mei=Haruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakagoshiAyako en-aut-sei=Nakagoshi en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WadaMaki en-aut-sei=Wada en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UkaMayu en-aut-sei=Uka en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AkagiNoriaki en-aut-sei=Akagi en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Radiological Technology, Okayama University Medical School kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Okayama University Medical School kn-affil= affil-num=6 en-affil=Department of Radiological Technology, Okayama University Medical School kn-affil= affil-num=7 en-affil=Department of Radiological Technology, Okayama University Medical School kn-affil= affil-num=8 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=photon-counting detector CT kn-keyword=photon-counting detector CT en-keyword=energy integrating detector CT kn-keyword=energy integrating detector CT en-keyword=computed tomography kn-keyword=computed tomography en-keyword=contrast medium amount kn-keyword=contrast medium amount en-keyword=reduction kn-keyword=reduction END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=95 end-page=106 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Roles of Neuropeptide Y in Respiratory Disease Pathogenesis via the Airway Immune Response en-subtitle= kn-subtitle= en-abstract= kn-abstract=The lungs are very complex organs, and the respiratory system performs the dual roles of repairing tissue while protecting against infection from various environmental stimuli. Persistent external irritation disrupts the immune responses of tissues and cells in the respiratory system, ultimately leading to respiratory disease. Neuropeptide Y (NPY) is a 36-amino-acid polypeptide and a neurotransmitter that regulates homeostasis. The NPY receptor is a seven-transmembrane-domain G-protein-coupled receptor with six subtypes (Y1, Y2, Y3, Y4, Y5, and Y6). Of these receptors, Y1, Y2, Y4, and Y5 are functional in humans, and Y1 plays important roles in the immune responses of many organs, including the respiratory system. NPY and the Y1 receptor have critical roles in the pathogenesis of asthma, chronic obstructive pulmonary disease, and idiopathic pulmonary fibrosis. The effects of NPY on the airway immune response and pathogenesis differ among respiratory diseases. This review focuses on the involvement of NPY in the airway immune response and pathogenesis of various respiratory diseases. en-copyright= kn-copyright= en-aut-name=ItanoJunko en-aut-sei=Itano en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KiuraKatsuyuki en-aut-sei=Kiura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyaharaNobuaki en-aut-sei=Miyahara en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= en-keyword=neuropeptide y kn-keyword=neuropeptide y en-keyword=Y1 receptor kn-keyword=Y1 receptor en-keyword=airway immune response kn-keyword=airway immune response en-keyword=bronchial epithelial cells kn-keyword=bronchial epithelial cells en-keyword=respiratory disease kn-keyword=respiratory disease END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=9 end-page=13 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prostate Biopsy May Not Be Indicated Early after Bacillus Calmette Gu?rin Treatment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bacillus Calmette-Gu?rin (BCG) treatment for non-muscle-invasive bladder cancer frequently causes an intraprostatic BCG granuloma. We investigated the optimal timing for a prostate biopsy after BCG treatment by retrospectively analyzing the cases of 22 patients with non-muscle-invasive bladder cancer who underwent a prostate biopsy after BCG treatment at our institute (2013-2017). Biopsies were indicated for a rising prostate-specific antigen (PSA) level, positive digital rectal examination findings, or the appearance of de novo low apparent diffusion coefficient lesions on MRI. The control group was comprised of 28 age- and PSA-matched patients. The relationships among the cancer detection rate and the patients’ PSA levels and MRI findings were analyzed. Prostate cancer was detected by biopsy in only 13.9% (3/22) of the patients in the BCG group but in 78.5% (22/28) of the control patients (p=0.0001). The three patients in the BCG group in whom prostate cancer was detected had all undergone the biopsy > 1 year after their BCG treatment. The remaining biopsies were performed within 1 year after BCG treatment and resulted in no diagnoses of prostate cancer. We suggest that performing a prostate biopsy early after BCG treatment is not informative or useful. en-copyright= kn-copyright= en-aut-name=AkagiNaoki en-aut-sei=Akagi en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KanematsuAkihiro en-aut-sei=Kanematsu en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShigesakaKoji en-aut-sei=Shigesaka en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShimataniKimihiro en-aut-sei=Shimatani en-aut-mei=Kimihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoShingo en-aut-sei=Yamamoto en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Urology, Hyogo Medical University kn-affil= affil-num=2 en-affil=Department of Urology, Hyogo Medical University kn-affil= affil-num=3 en-affil=Department of Urology, Hyogo Medical University kn-affil= affil-num=4 en-affil=Department of Urology, Hyogo Medical University kn-affil= affil-num=5 en-affil=Department of Urology, Hyogo Medical University kn-affil= en-keyword=bacillus Calmette-Gu?rin kn-keyword=bacillus Calmette-Gu?rin en-keyword=prostate granuloma kn-keyword=prostate granuloma en-keyword=prostate cancer kn-keyword=prostate cancer en-keyword=bladder cancer kn-keyword=bladder cancer en-keyword=prostate biopsy kn-keyword=prostate biopsy END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=1 end-page=8 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Role of Macrophages in Liver Fibrosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Liver fibrosis, which ultimately leads to liver cirrhosis and hepatocellular carcinoma, is a major health burden worldwide. The progression of liver fibrosis is the result of the wound-healing response of liver to repeated injury. Hepatic macrophages are cells with high heterogeneity and plasticity and include tissue-resident macrophages termed Kupffer cells, and recruited macrophages derived from circulating monocytes, spleen and peritoneal cavity. Studies have shown that hepatic macrophages play roles in the initiation and progression of liver fibrosis by releasing inflammatory cytokines/chemokines and pro-fibrogenic factors. Furthermore, the development of liver fibrosis has been shown to be reversible. Hepatic macrophages have been shown to alternately regulate both the regression and turnover of liver fibrosis by changing their phenotypes during the dynamic progression of liver fibrosis. In this review, we summarize the role of hepatic macrophages in the progression and regression of liver fibrosis. en-copyright= kn-copyright= en-aut-name=SunCuiming en-aut-sei=Sun en-aut-mei=Cuiming kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pathology and Experimental Medicine, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=ERK-MAPK kn-keyword=ERK-MAPK en-keyword=SPRED2 kn-keyword=SPRED2 en-keyword=fibrosis kn-keyword=fibrosis en-keyword=macrophages kn-keyword=macrophages END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=2202 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240125 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Endoscopic and clinical features of gastric emphysema en-subtitle= kn-subtitle= en-abstract= kn-abstract=Gastric emphysema is characterized by the presence of intramural gas in the stomach without bacterial infection. Due to its rarity, most reports on gastric emphysema have been limited to single-case studies, and this condition's clinical and endoscopic features have not been thoroughly investigated. In this study, we analyzed 45 patients with gastric emphysema from 10 institutions and examined their characteristics, endoscopic features, and outcomes. The mean age at diagnosis of gastric emphysema in our study population (35 males and 10 females) was 68.6 years (range, 14-95 years). The top five underlying conditions associated with gastric emphysema were the placement of a nasogastric tube (26.7%), diabetes mellitus (20.0%), post-percutaneous endoscopic gastrostomy (17.8%), malignant neoplasms (17.8%), and renal failure (15.6%). Among the 45 patients, 42 were managed conservatively with fasting and administration of proton pump inhibitors. Unfortunately, seven patients died within 30 days of diagnosis, and 35 patients experienced favorable recoveries. The resolution of gastric emphysema was confirmed in 30 patients through computed tomography (CT) scans, with a mean duration of 17.1 +/- 34.9 days (mean +/- standard deviation [SD], range: 1-180 days) from the time of diagnosis to the disappearance of the gastric intramural gas. There were no instances of recurrence. Endoscopic evaluation was possible in 18 patients and revealed that gastric emphysema presented with features such as redness, erosion, coarse mucosa, and ulcers, with fewer mucosal injuries on the anterior wall (72.2%), a clear demarcation between areas of mucosal injury and intact mucosa (61.1%), and predominantly longitudinal mucosal injuries on the stomach folds (50.0%). This study is the first English-language report to analyze endoscopic findings in patients with gastric emphysema. 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=TakenakaRyuta en-aut-sei=Takenaka en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ToyokawaTatsuya en-aut-sei=Toyokawa en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KitaMasahide en-aut-sei=Kita en-aut-mei=Masahide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsuzukiTakao en-aut-sei=Tsuzuki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshiokaMasao en-aut-sei=Yoshioka en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=GotodaTatsuhiro en-aut-sei=Gotoda en-aut-mei=Tatsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkanoueShotaro en-aut-sei=Okanoue en-aut-mei=Shotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MatsubaraMinoru en-aut-sei=Matsubara en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SakaguchiChihiro en-aut-sei=Sakaguchi en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology, National Hospital Organization Fukuyama Medical Center kn-affil= affil-num=4 en-affil=Department of Internal Medicine, Okayama City Hospital kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=6 en-affil=Department of Internal Medicine, Okayama Saiseikai General Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Kurashiki Central Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology, Mitoyo General Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology, Sumitomo Besshi Hospital kn-affil= affil-num=10 en-affil=Department of Endoscopy, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=24 article-no= start-page=3619 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231207 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characteristic Mean Kurtosis Values in Simple Diffusion Kurtosis Imaging of Dentigerous Cysts en-subtitle= kn-subtitle= en-abstract= kn-abstract=We evaluated the usefulness of simple diffusion kurtosis (SD) imaging, which was developed to generate diffusion kurtosis images simultaneously with an apparent diffusion coefficient (ADC) map for 27 cystic disease lesions in the head and neck region. The mean kurtosis (MK) and ADC values were calculated for the cystic space. The MK values were dentigerous cyst (DC): 0.74, odontogenic keratocyst (OKC): 0.86, ranula (R): 0.13, and mucous cyst (M): 0, and the ADC values were DC: 1364 × 10?6 mm2/s, OKC: 925 × 10?6 mm2/s, R: 2718 × 10?6 mm2/s, and M: 2686 × 10?6 mm2/s. The MK values of DC and OKC were significantly higher than those of R and M, whereas their ADC values were significantly lower. One reason for the characteristic signal values in diffusion-weighted images of DC may be related to content components such as fibrous tissue and exudate cells. When imaging cystic disease in the head and neck region using SD imaging, the maximum b-value setting at the time of imaging should be limited to approximately 1200 s/mm2 for accurate MK value calculation. This study is the first to show that the MK values of DC are characteristically higher than those of other cysts. en-copyright= kn-copyright= en-aut-name=FukumuraYuka en-aut-sei=Fukumura

association between long-term exposure to particulate matter having an aerodynamic diameter of 2.5 μm or less (PM2.5) and diabetes mellitus (DM), but few studies have focused on Asian subjects. We thus examined the association between long-term exposure to PM2.5 and DM prevalence in Okayama City, Japan. We included 76,591 participants who had received basic health checkups in 2006 and 2007. We assigned the census-level modeled PM2.5 data from 2006 and 2007 to each participant and defined DM using treatment status and the blood testing. PM2.5 was associated with DM prevalence, and the prevalence ratio (95% confidence interval) was 1.10 (1.00-1.20) following each interquartile range increase (2.1 μg/m3) in PM2.5. This finding is consistent with previous results and suggests that long-term exposure to PM2.5 is associated with an increased prevalence of DM in Okayama City, Japan, where the PM2.5 level is lower than in other cities in Asian countries. en-copyright= kn-copyright= en-aut-name=TaniYasunari en-aut-sei=Tani en-aut-mei=Yasunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KashimaSaori en-aut-sei=Kashima en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuzukiEtsuji en-aut-sei=Suzuki en-aut-mei=Etsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Environmental Health Sciences Laboratory, Graduate School of Advanced Science and Engineering, Center for the Planetary Health and Innovation Science, The IDEC Institute, Hiroshima University kn-affil= affil-num=3 en-affil=Center for Innovate Clinical Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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 Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=air pollution kn-keyword=air pollution en-keyword=diabetes mellitus kn-keyword=diabetes mellitus en-keyword=epidemiology kn-keyword=epidemiology en-keyword=glycosylated hemoglobin kn-keyword=glycosylated hemoglobin en-keyword=particulate matter kn-keyword=particulate matter END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=5 article-no= start-page=499 end-page=509 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Neurological Analysis Based on the Terminal End of the Spinal Cord and the Narrowest Level of Injured Spine in Thoracolumbar Spinal Injuries en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to clarify neurological differences among the epiconus, conus medullaris, and cauda equina syndromes. Eighty-seven patients who underwent surgery for acute thoracolumbar spinal injuries were assessed. We defined the epiconus as the region from the terminal end of the spinal cord to the proximal 1.0 to 2.25 vertebral bodies, the conus medullaris as the region proximal to < 1.0 vertebral bodies, and the cauda equina as the distal part of the nerve roots originating from the spinal cord. On the basis of the distance from the terminal end of the spinal cord to the narrowest level of the spinal canal, the narrowest levels were ordered as follows: the epiconus followed by the conus medullaris and cauda equina. The narrowest levels were the epiconus in 22 patients, conus medullaris in 37 patients, and cauda equina in 25 patients. On admission, significantly more patients had a narrowed epiconus of Frankel grades A-C than a narrowed cauda equina. At the final follow-up, there were no significant differences in neurological recovery among those with epiconus, conus medullaris, or cauda equina syndrome. Anatomically classifying the narrowest lesion is useful for clarifying the differences and similarities among these three syndromes. en-copyright= kn-copyright= en-aut-name=HatakeyamaYuji en-aut-sei=Hatakeyama en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HongoMichio en-aut-sei=Hongo en-aut-mei=Michio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KidoTadato en-aut-sei=Kido en-aut-mei=Tadato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UrayamaMasakazu en-aut-sei=Urayama en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KasukawaYuji en-aut-sei=Kasukawa en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SasakiHiroshi en-aut-sei=Sasaki en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AizawaToshiaki en-aut-sei=Aizawa en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KudoDaisuke en-aut-sei=Kudo en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KimuraRyota en-aut-sei=Kimura en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OnoYuichi en-aut-sei=Ono en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KasamaFumihito en-aut-sei=Kasama en-aut-mei=Fumihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MiyakoshiNaohisa en-aut-sei=Miyakoshi en-aut-mei=Naohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Akita Red Cross Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Akita Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Ogachi Central Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Noshiro Kousei Medical Center kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Kitaakita Municipal Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Akita Red Cross Hospital kn-affil= affil-num=11 en-affil=Department of Orthopaedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=12 en-affil=Department of Orthopaedic Surgery, Akita University Graduate School of Medicine kn-affil= en-keyword=thoracolumbar spinal injury kn-keyword=thoracolumbar spinal injury en-keyword=terminal end of spinal cord kn-keyword=terminal end of spinal cord en-keyword=conus medullaris kn-keyword=conus medullaris en-keyword=epiconus syndrome kn-keyword=epiconus syndrome en-keyword=cauda equina syndrome kn-keyword=cauda equina syndrome END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=11491 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230717 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relationships of rapid eating with visceral and subcutaneous fat mass and plasma adiponectin concentration en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rapid eating has been demonstrated to be associated with obesity and overweight. However, few studies have characterized the separate relationships of eating speed with visceral and subcutaneous fat mass or circulating adiponectin concentration. We hypothesized that rapid eating is associated with the larger visceral fat tissue (VFT) area and lower adiponectin concentration, but not with the subcutaneous fat tissue (SFT) area in men and women. We performed a cross-sectional study of 712 adults aged 20?86 years (528 men and 184 women; mean?±?SD age 59.36?±?13.61 years). The participants completed a self-reported questionnaire, and underwent anthropometric and laboratory measurements and computed tomographic imaging of the abdomen as a part of annual medical check-ups. Multivariate linear regression analyses revealed that rapid eating was associated with larger visceral (B?=?24.74; 95% CI 8.87?40.61, p?=?0.002) and subcutaneous fat areas (B?=?31.31; 95% CI 12.23?50.38, p?=?0.001), lower adiponectin concentration (B?=????2.92; 95% CI???4.39????1.46, p? METHODS: The 3DDSA data from 9 aneurysms were processed to obtain volumetric models suitable for the stereolithography apparatus. The resulting models were filled with iodinated contrast media. 3D rotational angiography of the models was carried out, and the aneurysm geometry was compared with the original patient data. The accuracy of the 3D-printed hollow models' sizes and shapes was evaluated using the nonparametric Wilcoxon signed-rank test and the Dice coefficient index.
RESULTS: The aneurysm volumes ranged from 34.1 to 4609.8 mm 3 (maximum diameters 5.1-30.1 mm), and no statistically significant differences were noted between the patient data and the 3D-printed models (P = 0.4). Shape analysis of the aneurysms and related arteries indicated a high level of accuracy (Dice coefficient index value: 88.1%-97.3%; mean + SD: 93.6% +/- 2.5%). The vessel wall thickness of the 3D-printed hollow models was 0.4 mm for the parent and 0.2 mm for small branches and aneurysms, almost the same as the patient data.
CONCLUSIONS: The WC technique, which involves volume rendering of 3DDSAs, can provide a detailed description of the contrast enhancement of intracranial vessels and aneurysms at arbitrary depths. These models can provide precise anatomic information and be used for simulations of endovascular treatment. en-copyright= kn-copyright= en-aut-name=HarumaJun en-aut-sei=Haruma en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugiuKenji en-aut-sei=Sugiu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HoshikaMinori en-aut-sei=Hoshika en-aut-mei=Minori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiramatsuMasafumi en-aut-sei=Hiramatsu en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HishikawaTomohito en-aut-sei=Hishikawa en-aut-mei=Tomohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MuraiSatoshi en-aut-sei=Murai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishiKazuhiko en-aut-sei=Nishi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamaokaYoko en-aut-sei=Yamaoka en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SatoYu en-aut-sei=Sato en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=EbisudaniYuki en-aut-sei=Ebisudani en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=EdakiHisanori en-aut-sei=Edaki en-aut-mei=Hisanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KimuraRyu en-aut-sei=Kimura en-aut-mei=Ryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Digital imaging and communications in medicine data kn-keyword=Digital imaging and communications in medicine data en-keyword=Intracranial aneurysm kn-keyword=Intracranial aneurysm en-keyword=Three-dimensional printing kn-keyword=Three-dimensional printing END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=3 article-no= start-page=247 end-page=253 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202206 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Analysis of Immunity against Measles, Mumps, Rubella, and Varicella Zoster in Adult Recipients of Allogeneic Hematopoietic Stem Cell Transplantation: A Single-Center Experience en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vaccine-preventable disease (VPD) infections are more severe in immunocompromised hosts. Vaccination against measles, mumps, rubella, and varicella zoster (VZV) (MMRV) is therefore recommended for hematopoietic stem cell transplantation (HCT) recipients. However, studies on adult HCT recipients with VPD infections are limited. At our institution, we have systematically conducted serological MMRV tests as a part of check-up examinations during long-term follow-up (LTFU) after HCT since 2015. This retrospective study aimed to evaluate changes in the serostatus between before and 2 years after allogeneic HCT. Among 161 patients, the pre-transplant seropositivity was 82.7% for measles, 86.8% for mumps, 84.2% for rubella, and 94.3% for VZV. Among 56 patients who underwent LTFU including serological MMRV tests at 2 years after HCT, the percentages maintaining seroprotective antibody levels for measles, mumps, rubella and VZV were 71.5% (40/56), 51.8% (29/56), 48.2% (27/56), and 60.7% (34/56), respectively. Vaccination was recommended for 22 patients, and 12 were vaccinated. Among the 12 vaccinated patients, rates of seroconversion were examined in 2-6 patients for each of the four viruses. They were 100% (3/3) for measles, 33.3% (1/3) for mumps, 50% (3/6) for rubella, and 0% (0/2) for VZV. Further studies are warranted to clarify the effect of vaccination in adult HCT recipients. en-copyright= kn-copyright= en-aut-name=YoshidaShohei en-aut-sei=Yoshida en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KamoiChihiro en-aut-sei=Kamoi en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KitamuraWataru en-aut-sei=Kitamura en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujiwaraHideaki en-aut-sei=Fujiwara en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AsadaNoboru en-aut-sei=Asada en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishimoriHisakazu en-aut-sei=Nishimori en-aut-mei=Hisakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujiiKeiko en-aut-sei=Fujii en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MatsuokaKen-ichi en-aut-sei=Matsuoka en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=vaccine-preventable disease kn-keyword=vaccine-preventable disease en-keyword=vaccination kn-keyword=vaccination en-keyword=allogeneic hematopoietic stem cell transplantation kn-keyword=allogeneic hematopoietic stem cell transplantation en-keyword=adult kn-keyword=adult END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=満期産児の出生体重SD値とその後の健康・行動発達の関連　〜21世紀出生児縦断調査より〜 kn-title=Associations of Birth Weight for Gestational Age with Child Health and Neurodevelopment among Term Infants: A Nationwide Japanese Population-Based Study en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=TamaiKei en-aut-sei=Tamai en-aut-mei=Kei kn-aut-name=玉井圭 kn-aut-sei=玉井 kn-aut-mei=圭 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=2 article-no= start-page=187 end-page=193 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202204 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between the Remifentanil Dose during Anesthesia and Postoperative pain en-subtitle= kn-subtitle= en-abstract= kn-abstract=Remifentanil is an ultra-short-acting opioid that sometimes causes opioid-induced hyperalgesia, which has led to controversy regarding the association between intraoperative remifentanil administration and postoperative pain. This study aimed to assess the effects of the intraoperative remifentanil dose on postoperative pain. Patients undergoing esophageal, gastric/hepatobiliary, or intestinal/colon surgery and using postoperative patient-controlled epidural analgesia were analyzed. The patients were divided into two groups based on the average intraoperative remifentanil dose (high-dose remifentanil [HR] group: ?0.1 μg/kg/min; low-dose remifentanil [LR] group: <0.1 μg/kg/min). In all, 406 patients met the inclusion criteria. A significant difference in the average dose of remifentanil was seen between the groups during the anesthesia period (0.14±0.05 vs. 0.07±0.02 μg/kg/min). However, no significant difference was seen in pre- or intraoperative patient characteristics. Numerical rating scale (NRS) scores on postoperative day 1 were similar between the groups (HR: 1.7±2.0; LR: 1.7±2.0; p=0.74). The incidence of poor pain control (NRS > 3/10) was also similar between the groups (HR: 14%; LR: 16%; p=0.57). Older age (> 60 years) and type of surgery (esophageal surgery) were associated with worse postoperative NRS scores. No significant association was seen between the intraoperative remifentanil dose and postoperative NRS scores following thoracoabdominal surgery with postoperative epidural pain management. en-copyright= kn-copyright= en-aut-name=RenWanxu en-aut-sei=Ren en-aut-mei=Wanxu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsusakiTakashi en-aut-sei=Matsusaki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Abugri Osman Bright en-aut-sei=Abugri Osman Bright en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=high-dose remifentanil kn-keyword=high-dose remifentanil en-keyword=postoperative numerical rating scale kn-keyword=postoperative numerical rating scale en-keyword=type of surgery kn-keyword=type of surgery en-keyword=epidural block kn-keyword=epidural block END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=2 article-no= start-page=105 end-page=111 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202204 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pathological Complete Response Patients after Neoadjuvant Chemotherapy in Breast Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cases of breast cancer metastasis after achieving a pathological complete response (pCR) with neoadjuvant chemotherapy (NAC) are sometimes encountered in clinical practice. We investigated the prognostic factors for pCR in patients with breast cancer after NAC. This retrospective cohort study included patients with localized breast cancer who underwent NAC followed by surgery between 2004 and 2020 and achieved a pCR. The associations between clinical factors and distant metastasis-free survival rate were statistically analyzed. We analyzed data for 127 patients. Twelve patients (9.4%) had distant metastases, and seven (5.5%) died. For estrogen receptor (ER)-positive patients, the distant metastasis-free survival rate was 94.6% for both 5 and 8 years. In contrast, ER-negative patients had a distant metastasis-free survival rate of 87.6% and 85.4% for 5 and 8 years (p=0.094), respectively. In cT0-2 patients, the distant metastasis-free survival rate was 92.4% for 5 years and 90.5% for 8 years, whereas in cT3-4 patients, the distant metastasis-free survival rate was 83.5% for 5 years and 83.5% for 8 years (p=0.301). This study suggested that patients with ER-negative, pre-NAC cT3 or T4 breast cancer who had achieved a pCR after NAC tended to have a worse prognosis. en-copyright= kn-copyright= en-aut-name=TakaokaMegumi en-aut-sei=Takaoka en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhsumiShozo en-aut-sei=Ohsumi en-aut-mei=Shozo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IkejiriHaruka en-aut-sei=Ikejiri en-aut-mei=Haruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShidaharaTomohiro en-aut-sei=Shidahara en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyoshiYuichiro en-aut-sei=Miyoshi en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakahashiMina en-aut-sei=Takahashi en-aut-mei=Mina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakashimaSeiki en-aut-sei=Takashima en-aut-mei=Seiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AogiKenjiro en-aut-sei=Aogi en-aut-mei=Kenjiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Breast Oncology, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=2 en-affil=Department of Breast Oncology, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=3 en-affil=Department of Breast Oncology, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=4 en-affil=Department of Breast Oncology, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=5 en-affil=Department of Breast Oncology, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=6 en-affil=Department of Breast Oncology, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=7 en-affil=Department of Breast Oncology, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=8 en-affil=Department of Breast Oncology, National Hospital Organization Shikoku Cancer Center kn-affil= en-keyword=breast kn-keyword=breast en-keyword=carcinoma kn-keyword=carcinoma en-keyword=neoadjuvant therapy kn-keyword=neoadjuvant therapy en-keyword=prognosis kn-keyword=prognosis END start-ver=1.4 cd-journal=joma no-vol=2022 cd-vols= no-issue= article-no= start-page=3157841 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Association of Postprandial Triglyceride Variability with Renal Dysfunction and Microalbuminuria in Patients with Type 2 Diabetic Mellitus: A Retrospective and Observational Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective. We examined whether or not day-to-day variations in lipid profiles, especially triglyceride (TG) variability, were associated with the exacerbation of diabetic kidney disease. Methods. We conducted a retrospective and observational study. First, 527 patients with type 2 diabetes mellitus (DM) who had had their estimated glomerular filtration rate (eGFR) checked every 6 months since 2012 for over 5 years were registered. Variability in postprandial TG was determined using the standard deviation (SD), SD adjusted (Adj-SD) for the number of measurements, and maximum minus minimum difference (MMD) during the first three years of follow-up. The endpoint was a & GE;40% decline from baseline in the eGFR, initiation of dialysis or death. Next, 181 patients who had no micro- or macroalbuminuria in February 2013 were selected from among the 527 patients for an analysis. The endpoint was the incidence of microalbuminuria, initiation of dialysis, or death. Results. Among the 527 participants, 110 reached a & GE;40% decline from baseline in the eGFR or death. The renal survival was lower in the higher-SD, higher-Adj-SD, and higher-MMD groups than in the lower-SD, lower-Adj-SD, and lower-MMD groups, respectively (log-rank test p=0.0073, 0.0059, and 0.0195, respectively). A lower SD, lower Adj-SD, and lower MMD were significantly associated with the renal survival in the adjusted model (hazard ratio, 1.62, 1.66, 1.59; 95% confidence intervals, 1.05-2.53, 1.08-2.58, 1.04-2.47, respectively). Next, among 181 participants, 108 developed microalbuminuria or death. The nonincidence of microalbuminuria was lower in the higher-SD, higher-Adj-SD, and higher-MMD groups than in the lower-SD, lower-Adj-SD, and lower-MMD groups, respectively (log-rank test p=0.0241, 0.0352, and 0.0474, respectively). Conclusions. Postprandial TG variability is a novel risk factor for eGFR decline and the incidence of microalbuminuria in patients with type 2 DM. en-copyright= kn-copyright= en-aut-name=Matsuoka-UchiyamaNatsumi

stent deployment from the left main trunk (LMT) to the left anterior descending artery (LAD) without plaque at the LMT ostium has not been reported. A 60-year-old Japanese man with a history of scleroderma, pulmonary fibrosis, and type 2 diabetes developed acute myocardial infarction of the right coronary artery (RCA) and was treated by emergency percutaneous coronary intervention (PCI) for RCA. Nine days later he underwent PCI from the LMT to the LAD. Follow-up coronary angiography (CAG) at 9 and 21 months post-PCI did not reveal ISR in any lesion, but the patient experienced cardiac arrest at 25 months post-PCI. Emergency CAG after resuscitation revealed ISR of the LMT ostium; emergency PCI was conducted. The development of ISR at the ostium of the LMT although the patient was free of plaque 4 months before is extremely unusual. This rare ISR of the LMT ostium progressed rapidly after follow-up CAG revealed no ISR at 21 months post-stent implantation. en-copyright= kn-copyright= en-aut-name=NaitoYoichiro en-aut-sei=Naito en-aut-mei=Yoichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshikawaMasaki en-aut-sei=Yoshikawa en-aut-mei=Masaki 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=KuboMotoki en-aut-sei=Kubo en-aut-mei=Motoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugiyamaHiroyasu en-aut-sei=Sugiyama en-aut-mei=Hiroyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuzukiHideyuki en-aut-sei=Suzuki en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujitaShinpei en-aut-sei=Fujita en-aut-mei=Shinpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AraiYasunori en-aut-sei=Arai en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakahashiSho en-aut-sei=Takahashi en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KatoYuichi en-aut-sei=Kato en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YoshidaYu en-aut-sei=Yoshida en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=AkaiHiroaki en-aut-sei=Akai en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MurakamiShuhei en-aut-sei=Murakami en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=10 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=11 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=12 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=13 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=14 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=left main trunk kn-keyword=left main trunk en-keyword=in-stent restenosis kn-keyword=in-stent restenosis en-keyword=cardiopulmonary arrest kn-keyword=cardiopulmonary arrest END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=89 end-page=92 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Completely Video-assisted Thoracoscopic Lobectomy for Congenital Lobar Emphysema in a Young Adult en-subtitle= kn-subtitle= en-abstract= kn-abstract=Congenital lobar emphysema (CLE) is defined as the hyperinflation of pulmonary lobes due to obstruction of the flow of air via a known or unknown etiology, which causes pressure symptoms in the adjacent organs. CLE is mainly diagnosed in the neonatal period, and very few adult cases have been reported. Here we report a 34-year-old male with muscular dystrophy who was diagnosed with CLE on examination. He underwent a right lower lobectomy via 3-portal completely video-assisted thoracoscopic surgery, and his symptoms improved. Thoracoscopic surgery helped preserve the respiratory muscles and led to the improvement of respiratory function in this patient. en-copyright= kn-copyright= en-aut-name=RyukoTsuyoshi en-aut-sei=Ryuko en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoHiromasa en-aut-sei=Yamamoto en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuzawaKen en-aut-sei=Suzawa en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtaniShinji en-aut-sei=Otani en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamaneMasaomi en-aut-sei=Yamane en-aut-mei=Masaomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= en-keyword=congenital lobar emphysema, kn-keyword=congenital lobar emphysema, en-keyword=adult, kn-keyword=adult, en-keyword=lobectomy, kn-keyword=lobectomy, en-keyword=completely video-assisted thoracoscopic surgery, kn-keyword=completely video-assisted thoracoscopic surgery, en-keyword=muscular dystrophy kn-keyword=muscular dystrophy END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=63 end-page=70 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Chidamide and Decitabine in Combination with a HAG Priming Regimen for Acute Myeloid Leukemia with TP53 Mutation en-subtitle= kn-subtitle= en-abstract= kn-abstract=We analyzed the treatment effects of chidamide and decitabine in combination with a HAG (homoharringtonine, cytarabine, G-CSF) priming regimen (CDHAG) in acute myeloid leukemia (AML) patients with TP53 mutation. Seven TP53 mutated AML patients were treated with CDHAG. The treatment effects were assessed using hemogram detection and bone marrow aspirate. The possible side effects were evaluated based on both hematological and non-hematological toxicity. Four of the seven patients were classified as having achieved complete remission after CDHAG treatment; one patient was considered to have achieved partial remission, and the remaining two patients were considered in non-remission. The overall response rate (ORR) to CDHAG was 71.4%. Regarding the side effects, the hematological toxicity level of the seven patients ranged from level III to level IV, and infections that occurred at lung, blood, and skin were recorded. Nausea, vomiting, liver injury, and kidney injury were also detected. However, all side effects were attenuated by proper management. The CDHAG regimen clearly improved the ORR (71.4%) of TP53-mutated AML patients, with no severe side effects. en-copyright= kn-copyright= en-aut-name=ZhangBei en-aut-sei=Zhang en-aut-mei=Bei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PeiZhixin en-aut-sei=Pei en-aut-mei=Zhixin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WangHongxia en-aut-sei=Wang en-aut-mei=Hongxia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WuHuimin en-aut-sei=Wu en-aut-mei=Huimin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WangJunjie en-aut-sei=Wang en-aut-mei=Junjie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=BaiJunjun en-aut-sei=Bai en-aut-mei=Junjun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SongQinglin en-aut-sei=Song en-aut-mei=Qinglin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Hematology, Jiaozuo People’s Hospital kn-affil= affil-num=2 en-affil=Department of Hematology, Jiaozuo People’s Hospital kn-affil= affil-num=3 en-affil=Department of Hematology, Jiaozuo People’s Hospital kn-affil= affil-num=4 en-affil=Department of Hematology, Jiaozuo People’s Hospital kn-affil= affil-num=5 en-affil=Department of Hematology, Jiaozuo People’s Hospital kn-affil= affil-num=6 en-affil=Department of Hematology, Jiaozuo People’s Hospital kn-affil= affil-num=7 en-affil=Department of Hematology, Jiaozuo People’s Hospital kn-affil= en-keyword=acute myeloid leukemia kn-keyword=acute myeloid leukemia en-keyword=chidamide kn-keyword=chidamide en-keyword=decitabine kn-keyword=decitabine en-keyword=HAG kn-keyword=HAG en-keyword=TP53 mutation kn-keyword=TP53 mutation END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=51 end-page=56 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Obesity’s Influence on Insulin Resistance in Pregnant Women with Polycystic Ovary Syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Polycystic ovary syndrome (PCOS) is a common endocrine metabolic disorder that is associated with high insulin resistance and obesity. However, ~70% of women with PCOS in Japan are non-obese. We retrospectively analyzed the cases of 163 Japanese women with PCOS who visited our Ob/Gyn department in 2006-2018 to determine which has a greater effect on insulin resistance: PCOS or obesity. We reviewed the women’s medical records and calculated their insulin resistance and insulin secretion. The women’s mean age and pre-pregnancy body mass index (BMI) were 30±5.8 years and 24.8±5.6 kg/m2, respectively; their mean ± SD fasting plasma glucose, 94.1±13.7 mg/dL; HOMA-IR, 2.1±2.0; QUICKI, 0.4±0.0; and HOMA-β, 108.9±88.0%. Sixtyeight women were pregnant, and 37% (n=25) were obese (BMI ? 25 kg/m2). Obesity had a greater effect on insulin resistance: fasting plasma glucose F(1, 53)=6.134, p<0.05; fasting insulin F(1, 53)=31.606, p<0.01; HOMA-IR F(1, 53)=31.670, p<0.01; QUICKI F(1, 53)=16.156, p<0.01. There was no significant difference in values other than QUICKI and testosterone between the women with and without PCOS. Obesity thus had a greater effect on increased insulin resistance in pregnant women with PCOS. Further studies of the insulin resistance of non-obese women with PCOS is needed, as non-obese women with PCOS are common in Asia. en-copyright= kn-copyright= en-aut-name=EtoEriko en-aut-sei=Eto en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TaniKazumasa en-aut-sei=Tani en-aut-mei=Kazumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=HayataKei en-aut-sei=Hayata en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=polycystic ovary syndrome kn-keyword=polycystic ovary syndrome en-keyword=insulin resistance kn-keyword=insulin resistance en-keyword=obesity kn-keyword=obesity en-keyword=pregnancy kn-keyword=pregnancy END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue= article-no= start-page=103 end-page=110 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201912 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=性的マイノリティ当事者の語りは聴き手の性的マイノリティへの印象や当惑感を改善する en-subtitle= kn-subtitle= en-abstract= kn-abstract=本研究の目的は，性的マイノリティ当事者の語りが，聴講者の性的マイノリティへの態度や認識に及ぼす変化を明らかにすることである．当事者が現職の学校教員と校長を対象に50分の講話をし，講演の前後に質問紙調査を行い，印象や当惑感，理解の困難さについて数値化し，変化を調べた．調査内容は，印象の測定にはSD法を使用し，印象の「身近さ」因子に含まれる6項目について7件法で回答を求め，当惑感については8項目，理解困難については2項目の尺度を使用し，6件法で回答を求めた．その結果，参加者は性的マイノリティをより身近に感じるようになり，当惑感や理解困難等の否定的な態度や認識が有意に軽減した． en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=前本浩希 kn-aut-sei=前本 kn-aut-mei=浩希 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=佐々木新 kn-aut-sei=佐々木 kn-aut-mei=新 aut-affil-num=2 ORCID= en-aut-name=OhmoriIori en-aut-sei=Ohmori en-aut-mei=Iori kn-aut-name=大守伊織 kn-aut-sei=大守 kn-aut-mei=伊織 aut-affil-num=3 ORCID= affil-num=1 en-affil=岡山大学特別支援教育特別専攻科 kn-affil= affil-num=2 en-affil=川崎医療福祉大学医療福祉学部 kn-affil= 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 en-keyword=自己開示 kn-keyword=自己開示 en-keyword=受容 kn-keyword=受容 en-keyword=性的マイノリティ kn-keyword=性的マイノリティ en-keyword=当事者の語り kn-keyword=当事者の語り END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=18 article-no= start-page=9512 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210909 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Short or Irregular Sleep Duration in Early Childhood Increases Risk of Injury for Primary School-Age Children: A Nationwide Longitudinal Birth Cohort in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study was to investigate the longitudinal relationship between shorter or irregular sleep duration (SD) in early childhood and increased risk of injury at primary school age using data from a nationwide survey in Japan. We categorized SD into seven groups: 6 h, 7 h, 8 h, 9 hrs, 10 or 11 h, >12 h, and irregular, based on questionnaire responses collected at 5.5 years old. The relationship between SD and incidence of injury at 5.5-nine years of age is shown. In addition, we completed a stratified analysis on children with or without problematic behavior at eight years old. We included 32,044 children, of which 6369 were classified as having an injury and 25,675 as not having an injury. Logistic regression model showed that shorter or irregular SD categories were associated with an increased adjusted odds ratio (aOR) for injuries (6 h: aOR 1.40, 95% confidence interval (CI) 1.19-1.66, 7 h: aOR 1.10, 95% CI, 0.98-1.23, 8 h: aOR 1.13, 95% CI, 1.02-1.26, irregular: aOR 1.26, 95% CI 1.10-1.43). The same tendency was observed with shorter or irregular SD in subgroups with or without behavioral problems. Shorter or irregular sleep habits during early childhood are associated with injury during primary school age. en-copyright= kn-copyright= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei 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=YamamotoHirotsugu en-aut-sei=Yamamoto en-aut-mei=Hirotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi 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, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=sleep habits kn-keyword=sleep habits en-keyword=trauma kn-keyword=trauma en-keyword=problematic behavior kn-keyword=problematic behavior en-keyword=longitudinal study kn-keyword=longitudinal study END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=4 article-no= start-page=517 end-page=521 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Arrhythmogenic Right Ventricular Cardiomyopathy Diagnosed during Hospitalization for Cardiac Arrest en-subtitle= kn-subtitle= en-abstract= kn-abstract=Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a genetically mediated cardiomyopathy charac-terized by progressive myocardial loss of the right ventricle and its replacement by fibrofatty tissue, causing dyskinesia, aneurysm, and/or arrhythmia. The prevalence of ARVC is estimated to be 1 in 2,000-5,000, with the condition accounting for up to 20% of sudden cardiac deaths in individuals < 35 years old. This report describes the case of 61-year-old Japanese who was diagnosed with ARVC after cardiac arrest (CA) and successful resusci-tation. After the sudden CA, the restoration of spontaneous circulation was achieved with appropriate resusci-tation, followed by the introduction of target temperature management in the intensive care unit. He was diag-nosed with ARVC based on angiography and histology results. An ICD (implantable cardioverter-defibrillator) was implanted, and he was discharged without neurological sequelae 1 month post-CA. ARVC is an important cause of sudden CA, and successfully resuscitated patients with right ventricular dilation should undergo testing to rule out ARVC. en-copyright= kn-copyright= en-aut-name=OchiMasahiko en-aut-sei=Ochi en-aut-mei=Masahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IidaAtsuyoshi en-aut-sei=Iida en-aut-mei=Atsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakahashiYuka en-aut-sei=Takahashi en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaMasamichi en-aut-sei=Tanaka en-aut-mei=Masamichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SaitoHironori en-aut-sei=Saito en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MikaneTakeshi en-aut-sei=Mikane en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FukeSoichiro en-aut-sei=Fuke en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Cardiology, Japan Red Cross Okayama Hospital kn-affil= affil-num=2 en-affil=Department of Emergency Medicine, Japan Red Cross Okayama Hospital kn-affil= affil-num=3 en-affil=Division of Pathology and Clinical Laboratories, National Cancer Center Hospital kn-affil= affil-num=4 en-affil=Department of Cardiology, Japan Red Cross Okayama Hospital kn-affil= affil-num=5 en-affil=Department of Cardiology, Japan Red Cross Okayama Hospital kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Emergency Medicine, Japan Red Cross Okayama Hospital kn-affil= affil-num=8 en-affil=Department of Cardiology, Japan Red Cross Okayama Hospital kn-affil= en-keyword=inverted T-wave kn-keyword=inverted T-wave en-keyword=right ventricular dilatation kn-keyword=right ventricular dilatation en-keyword=sudden cardiac arrest kn-keyword=sudden cardiac arrest en-keyword=sudden cardiac death kn-keyword=sudden cardiac death END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=4 article-no= start-page=479 end-page=486 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-term Multidisciplinary Rehabilitation Efficacy in Older Patients After Traumatic Brain Injury: Assessed by the Functional Independence Measure en-subtitle= kn-subtitle= en-abstract= kn-abstract=Instances of traumatic brain injury (TBI) in the elderly have been increasing along with the aging of popula-tions. In the present study, we examined the effect of aging on long-term multidisciplinary in-patient rehabili-tation efficacy after TBI. Sixty-three patients with physical and cognitive impairments after TBI were enrolled in this study. Patients were divided into 4 age groups (? 24, 25-44, 45-64, ? 65 years) and the clinical charac-teristics and rehabilitation efficacy of each age group were determined. Functional disability was evaluated using motor and cognitive Functional Independence Measure (FIM) scores. Rehabilitation efficacy was assessed by FIM gains during rehabilitation and compared among the groups. There were no statistically significant dif-ferences in motor and cognitive FIM gains among the age groups. However, cognitive FIM gain was limited in a subset of ? 65 patients, and initial cognitive measures could not predict cognitive FIM improvement. These results indicate that chronological age is insufficient to accurately predict rehabilitation efficacy in older TBI patients, and that such patients should be considered candidates for intensive rehabilitation programs based on these results. Accurate prognostication of rehabilitation efficacy with continuing data collection is important when using rehabilitation resources for older TBI patients. en-copyright= kn-copyright= en-aut-name=HaradaAkio en-aut-sei=Harada en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawaiNobuyuki en-aut-sei=Kawai en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OgawaTomoya en-aut-sei=Ogawa en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HatakeyamaTetsuhiro en-aut-sei=Hatakeyama en-aut-mei=Tetsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TamiyaTakashi en-aut-sei=Tamiya en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Faculty of Medicine, Kagawa University kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Kagawa Rehabilitation Hospital kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Faculty of Medicine, Kagawa University kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Faculty of Medicine, Kagawa University kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Faculty of Medicine, Kagawa University kn-affil= en-keyword=aging kn-keyword=aging en-keyword=Functional Independence Measure kn-keyword=Functional Independence Measure en-keyword=physical and cognitive impairments kn-keyword=physical and cognitive impairments en-keyword=traumatic brain injury kn-keyword=traumatic brain injury en-keyword=rehabilitation kn-keyword=rehabilitation END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=4 article-no= start-page=423 end-page=430 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Medial Meniscus Posterior Root Repair Using a Modified Mason-Allen Suture Can Prevent the Progression of Cartilage Degeneration on the Loading Surface of the Medial Compartment: A Second-Look Arthroscopic Evaluation en-subtitle= kn-subtitle= en-abstract= kn-abstract=The treatment of medial meniscus posterior root tears (MMPRTs) has evolved to include a variety of repair strategies. This study investigated the location of the articular cartilage degeneration during second-look arthroscopy after transtibial pullout repair with a modified Mason-Allen suture using FasT-Fix (F-MMA) in 22 patients with MMPRTs. Second-look arthroscopy was performed approximately 1 year postoperatively to eval-uate the healing status of the medial meniscus (MM). Articular cartilage degeneration was assessed using the International Cartilage Repair Society grade at primary surgery and again at second-look arthroscopy. Articular surfaces of the medial/lateral femoral condyles, the medial/lateral tibial plateaus, the patella and the trochlea were divided into several subcompartments (MF 1-9, LF 1-9, MT 1-5, LT 1-5, P 1-9, T 1-3). Clinical evaluations used the Japanese Knee Injury and Osteoarthritis Outcome, Lysholm, and International Knee Documentation Committee scores. Second-look arthroscopic findings showed complete healing of the MM posterior root in all patients. Significant differences between pullout repair and second-look arthroscopy were observed for MF 2 and 4, LF 7, and P 7. All clinical outcomes were improved. Our results indicate that this technique improves clinical outcomes postoperatively and may prevent the progression of cartilage degenera-tion on the loading surface of the medial knee compartment. en-copyright= kn-copyright= en-aut-name=TakihiraShota en-aut-sei=Takihira en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiranakaTakaaki en-aut-sei=Hiranaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KintakaKeisuke en-aut-sei=Kintaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KodamaYuya en-aut-sei=Kodama en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=MiyazawaShinichi en-aut-sei=Miyazawa en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University 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= en-keyword=articular cartilage kn-keyword=articular cartilage en-keyword=medial meniscus kn-keyword=medial meniscus en-keyword=modified Mason-Allen suture technique kn-keyword=modified Mason-Allen suture technique en-keyword=posterior root tear kn-keyword=posterior root tear en-keyword=second-look arthroscopy kn-keyword=second-look arthroscopy END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=4 article-no= start-page=403 end-page=413 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Surgical Treatment of Epiretinal Membrane en-subtitle= kn-subtitle= en-abstract= kn-abstract=Epiretinal membrane (ERM) is a common retinal disease characterized by cellular proliferation and metaplasia that lead to the formation of a pathological fibrocellular membrane immediately superjacent to the inner retinal surface. The vast majority of ERMs are considered idiopathic. However, ERM formation can result from various primary intraocular diseases, including retinal breaks and detachment, retinal vascular diseases, and vitreoretinal inflammatory conditions. Although ERMs are generally asymptomatic or cause mild metamorphopsia and/or a modest decrease in visual acuity, some can cause severe macular distortion and macular edema, resulting in significantly impaired function. Surgical removal of ERM is the only treatment, and improvements in vitrectomy systems have enabled less invasive treatment. However, there are currently no standardized criteria for ERM surgery, and the indications for surgery are determined from the patient’s subjective symptoms. Another problem with ERM surgery is that not all patients show satisfactory postoperative recovery of visual function. Thus, further research is needed to determine the criteria for ERM surgery and methods to improve the postoperative prognosis. en-copyright= kn-copyright= en-aut-name=MatobaRyo en-aut-sei=Matoba en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorizaneYuki en-aut-sei=Morizane en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=epiretinal membrane kn-keyword=epiretinal membrane en-keyword=vitrectomy kn-keyword=vitrectomy en-keyword=optical coherence tomography kn-keyword=optical coherence tomography en-keyword=internal limiting membrane kn-keyword=internal limiting membrane en-keyword=lamellar macular hole kn-keyword=lamellar macular hole END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=16 article-no= start-page=e020103 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210817 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Predictive Value of the Cardio-Ankle Vascular Index for Cardiovascular Events in Patients at Cardiovascular Risk en-subtitle= kn-subtitle= en-abstract= kn-abstract=BACKGROUND: Arterial stiffness is an important predictor of cardiovascular events; however, indexes for measuring arterial stiffness have not been widely incorporated into routine clinical practice. This study aimed to determine whether the cardio-ankle vascular index (CAVI), based on the blood pressure-independent stiffness parameter beta and reflecting arterial stiffness from the origin of the ascending aorta, is a good predictor of cardiovascular events in patients with cardiovascular disease risk factors in a large prospective cohort.

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

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

Treated with Nivolumab en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recurrent or metastatic head and neck squamous cell carcinoma (R/MHNSCC) has a poor prognosis. Although nivolumab is approved in Japan for treating R/MHNSCC, the response rate is low. Therefore, identifying pretreatment prognostic factors is necessary. This study assessed the utility of the neutrophil-to-lymphocyte ratio (NLR) and Glasgow Prognostic Score (GPS) as biomarkers of response to nivolumab. We retrospectively collected the data of 56 R/MHNSCC patients treated with nivolumab between May 2017 and December 2019. The Kaplan?Meier method and log-rank test were used to estimate overall survival (OS) and progression-free survival (PFS), and multivariate Cox hazard regression analysis was used to identify independent predictors of survival. Patients with a low pretreatment NLR had prolonged OS, and patients with a low pretreatment GPS had increased OS and PFS. A performance score (PS) of 0-1, development of immune-related adverse events, and GPS of 0-1 were significantly associated with OS in multivariate analysis. In summary, baseline pretreatment NLR and GPS are independently associated with OS in R/MHNSCC patients treated with nivolumab. Administration of nivolumab while maintaining the PS reflects a immune status of the host and leads to a good OS. en-copyright= kn-copyright= en-aut-name=ChikuieNobuyuki en-aut-sei=Chikuie en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamamotoTakao en-aut-sei=Hamamoto en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UedaTsutomu en-aut-sei=Ueda en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TaruyaTakayuki en-aut-sei=Taruya en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KonoTakashi en-aut-sei=Kono en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FuruieHiromi en-aut-sei=Furuie en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IshinoTakashi en-aut-sei=Ishino en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakenoSachio en-aut-sei=Takeno en-aut-mei=Sachio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Otorhinolaryngology, Head and Neck Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=2 en-affil=Department of Otorhinolaryngology, Head and Neck Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=3 en-affil=Department of Otorhinolaryngology, Head and Neck Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=4 en-affil=Department of Otorhinolaryngology, Head and Neck Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=5 en-affil=Department of Otorhinolaryngology, Head and Neck Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=6 en-affil=Department of Otorhinolaryngology, Head and Neck Surgery, Kure Medical Center and Chugoku Cancer Center kn-affil= affil-num=7 en-affil=Department of Otorhinolaryngology, Head and Neck Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=8 en-affil=Department of Otorhinolaryngology, Head and Neck Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= en-keyword=neutrophil-to-lymphocyte ratio kn-keyword=neutrophil-to-lymphocyte ratio en-keyword=nivolumab kn-keyword=nivolumab en-keyword=Glasgow Prognostic Score kn-keyword=Glasgow Prognostic Score en-keyword=recurrent or metastatic head and neck squamous cell carcinoma (R/MHNSCC) kn-keyword=recurrent or metastatic head and neck squamous cell carcinoma (R/MHNSCC) END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=3 article-no= start-page=289 end-page=297 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202106 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy and Safety of Early Intravenous Landiolol on Myocardial Salvage in Patients with ST-segment Elevation Myocardial Infarction before Primary Percutaneous Coronary Intervention: A Randomized Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Early treatment with an oral β-blocker is recommended in patients with a ST-segment?elevation myocardial infarction (STEMI). In this multicenter study, we evaluated the effects of a continuous administration of landiolol, an ultrashort-acting β-blocker, before primary percutaneous coronary intervention (PCI) on myocardial salvage and its safety in STEMI patients. A total of 47 Japanese patients with anterior or lateral STEMI undergoing a primary PCI within 12 h of symptom onset were randomized to receive intravenous landiolol (started at 3 μg/min/kg dose and continued to a total of 50 mg; n=23) or not (control; n=24). Patients with Killip class III or more were excluded. The primary outcome was the myocardial salvage index on cardiac magnetic resonance imaging (MRI) performed 5-7 days after the PCI. Cardiac MRI was performed in 35 patients (74%). The myocardial salvage index in the landiolol group was significantly greater than that in the control group (44.4±14.6% vs. 31.7±18.9%, respectively; p=0.04). There were no significant differences in adverse events at 24 h between the landiolol and control groups. A continuous administration of landiolol before a primary PCI may increase the degree of myocardial salvage without additional hemodynamic adverse effects within the first 24 h after STEMI. en-copyright= kn-copyright= en-aut-name=MiyamotoMasakazu en-aut-sei=Miyamoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OsawaKazuhiro en-aut-sei=Osawa en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=MoriAtsushi en-aut-sei=Mori en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshikawaMasaki en-aut-sei=Yoshikawa en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkaTakefumi en-aut-sei=Oka en-aut-mei=Takefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IchikawaKeishi en-aut-sei=Ichikawa en-aut-mei=Keishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=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, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiology, Tsuyama Central Hospital kn-affil= affil-num=5 en-affil=Department of Cardiology, Fukuyama City Hospital kn-affil= affil-num=6 en-affil=Department of Cardiology, Tsuyama Central Hospital kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=myocardial infarction kn-keyword=myocardial infarction en-keyword=landiolol kn-keyword=landiolol en-keyword= magnetic resonance imaging kn-keyword= magnetic resonance imaging en-keyword=STEMI kn-keyword=STEMI en-keyword=PCI kn-keyword=PCI END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210608 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Feasible kidney donation with living marginal donors, including diabetes mellitus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: To compare the donor outcomes of living donor kidney transplantation between standard donors (SDs) and marginal donors (MDs) including diabetic patients (MD + DM).
Methods: MDs were defined according to Japanese guideline criteria: (a) age >70-years, (b) blood pressure <= 130/80 mmHg on hypertension medicine, (c) body mass index >25 to <= 32 kg/m(2), (d) 24-h creatinine clearance >= 70 to <80 ml/min/1.73 m(2), and (e) hemoglobin A1c > 6.2 or <= 6.5 with oral diabetic medicine. Fifty-three of 114 donors were MDs. We compared donor kidney functions until 60 months postoperatively.
Results: No kidney function parameters were different between SDs and MDs. When comparing SD and MD + DM, MD + DM had a lower postoperative eGFR (48 vs. 41 (1 (month), p = .02), 49 vs. 40 (12, p < .01), 48 vs. 42 (24, p = .04), 47 vs. 38 (36, p = .01)) and the percentage of residual eGFR (SD vs. MD + DM: 63 vs. 57 (1 (month), p < .01), 63 vs. 57 (2, p < .01), 64 vs. 56 (12, p < .01), 63 vs. 57 (24, p < .01), 63 vs. 52 (36, p = .02)). However, when MD with a single risk factor of DM was compared to SD, the difference disappeared. Nine out of 12 (75%) MD + DM had >= 2 risk factors.
Conclusions: Although long-term observation of donor kidney function is necessary, careful MD + DM selection had the potential to expand the donor pool. en-copyright= kn-copyright=

Biomarkers Predict Cardiovascular Events in Patients With Type 2 Diabetes: A Multicenter Prospective Study With 5-Year Follow Up (U-CARE Study 2) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Although various biomarkers predict cardiovascular event (CVE) in patients with diabetes, the relationship of urinary glycan profile with CVE in patients with diabetes remains unclear. Methods: Among 680 patients with type 2 diabetes, we examined the baseline urinary glycan signals binding to 45 lectins with different specificities. Primary outcome was defined as CVE including cardiovascular disease, stroke, and peripheral arterial disease. Results: During approximately a 5-year follow-up period, 62 patients reached the endpoint. Cox proportional hazards analysis revealed that urinary glycan signals binding to two lectins were significantly associated with the outcome after adjustment for known indicators of CVE and for false discovery rate, as well as increased model fitness. Hazard ratios for these lectins (+1 SD for the glycan index) were UDA (recognizing glycan: mixture of Man5 to Man9): 1.78 (95% CI: 1.24-2.55, P = 0.002) and Calsepa [High-Man (Man2-6)]: 1.56 (1.19-2.04, P = 0.001). Common glycan binding to these lectins was high-mannose type of N-glycans. Moreover, adding glycan index for UDA to a model including known confounders improved the outcome prediction [Difference of Harrel's C-index: 0.028 (95% CI: 0.001-0.055, P = 0.044), net reclassification improvement at 5-year risk increased by 0.368 (0.045-0.692, P = 0.026), and the Akaike information criterion and Bayesian information criterion decreased from 725.7 to 716.5, and 761.8 to 757.2, respectively]. Conclusion: The urinary excretion of high-mannose glycan may be a valuable biomarker for improving prediction of CVE in patients with type 2 diabetes, and provides the rationale to explore the mechanism underlying abnormal N-glycosylation occurring in patients with diabetes at higher risk of CVE. en-copyright= kn-copyright= en-aut-name=MiseKoki en-aut-sei=Mise en-aut-mei=Koki kn-aut-name=

Expression in Adult T-Cell Leukemia/Lymphoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Differentiation between adult T-cell leukemia/lymphoma (ATLL) and peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS), is often challenging based on pathological findings alone. Although serum anti-HTLV-1 antibody positivity is required for ATLL diagnosis, this information is often not available at the time of pathological diagnosis. Therefore, we examined whether the expression of SOX4 and p16 would be helpful for differentiating the two disease entities. We immunohistochemically examined SOX4 and p16 expression (which have been implicated in ATLL carcinogenesis) in 11 ATLL patients and 20 PTCL-NOS patients and classified them into four stages according to the percentage of positive cells. Among the ATLL cases, 8/11 (73%) were SOX4-positive, while only 2/20 (10%) PTCL-NOS cases expressed SOX4. The mean total score was 4.2 (standard deviation (SD): 0.61) in the ATLL group and 0.50 (SD: 0.46) in the PTCL-NOS group (p < 0.001). Positive expression of p16 was noted in 4/11 (36%) patients with ATLL and 3/20 (15%) patients with PTCL-NOS, with mean total scores of 1.9 (SD: 0.64) and 0.70 (SD: 0.48) in the ATLL and PTCL-NOS groups, respectively (p = 0.141). These results suggest that SOX4 may be strongly expressed in ATLL compared to PTCL-NOS cases. Therefore, it may be helpful to perform immunohistochemical staining of SOX4 when pathologists face challenges discriminating between ATLL and PTCL-NOS. en-copyright= kn-copyright= en-aut-name=NasuAtsuko en-aut-sei=Nasu en-aut-mei=Atsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GionYuka en-aut-sei=Gion en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishikoriAsami en-aut-sei=Nishikori en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakamotoMisa en-aut-sei=Sakamoto en-aut-mei=Misa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=EgusaYuria en-aut-sei=Egusa en-aut-mei=Yuria kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujitaAzusa en-aut-sei=Fujita en-aut-mei=Azusa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=2 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=6 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=7 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=8 en-affil=Department of Pathology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= en-keyword=SOX4 kn-keyword=SOX4 en-keyword=p16 kn-keyword=p16 en-keyword=adult T-cell leukemia/lymphoma kn-keyword=adult T-cell leukemia/lymphoma en-keyword=peripheral T-cell lymphoma kn-keyword=peripheral T-cell lymphoma en-keyword=not otherwise specified kn-keyword=not otherwise specified END start-ver=1.4 cd-journal=joma no-vol=133 cd-vols= no-issue=1 article-no= start-page=43 end-page=48 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Epidemiological characteristics of novel coronavirus infection in Okayama Prefecture kn-title=岡山県における新型コロナウイルス感染症流行の疫学的特徴 en-subtitle= kn-subtitle= en-abstract=This article describes the epidemiological characteristics of coronavirus disease 2019 (COVID-19) observed in Okayama Prefecture. An epidemiological survey was performed using records from the Okayama Prefecture website and data from the newspaper Sanyo Shimbun (digital version). Infected patients were categorized into two groups: 25 patients infected during the first wave and 116 infected during the second wave. Notably, 52％ of the patients in the former group were aged ?50 years and 66％ in the latter group were aged 20-49 years. The percentages of Okayama City residents among the infected patients were 65％ and 73％, respectively. Three clusters were identified during the second wave. The interval (mean±SD) between the polymerase chain reaction (PCR) assay results for the index case and those for the cases of secondary infection was 0.8±0.8 days (n = 6 for the cases of secondary infection) during the first wave and 2.0±1.4 days (n = 62 for the cases of secondary infection) during the second wave. As of August 24, the percentage of cumulative infected cases (7.5/100,000 patients) in Okayama Prefecture was lower than that the national level (49.3/100,000 patients). These results indicate that Okayama Prefecture has controlled the COVID-19 pandemic relatively well, primarily through the consistent implementation of public health measures, such as early case identification, careful contact tracing, and prompt PCR testing. Strict enforcement of the aforementioned measures is important to prevent or offset the effects of the third wave of COVID-19 that is expected during the influenza epidemic season. kn-abstract= en-copyright= kn-copyright= en-aut-name=HigashionnaTsukasa en-aut-sei=Higashionna en-aut-mei=Tsukasa kn-aut-name=東恩納司 kn-aut-sei=東恩納 kn-aut-mei=司 aut-affil-num=1 ORCID= en-aut-name=SendoToshiaki en-aut-sei=Sendo en-aut-mei=Toshiaki kn-aut-name=千堂年昭 kn-aut-sei=千堂 kn-aut-mei=年昭 aut-affil-num=2 ORCID= en-aut-name=KusanoNobuchika en-aut-sei=Kusano en-aut-mei=Nobuchika kn-aut-name=草野 展周 kn-aut-sei=草野 kn-aut-mei=展周 aut-affil-num=3 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name=塚原宏一 kn-aut-sei=塚原 kn-aut-mei=宏一 aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil=岡山大学病院　薬剤部 岡山大学病院　感染制御部 affil-num=2 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil=岡山大学病院　薬剤部 affil-num=3 en-affil=Section of Infection Control and Prevention, Okayama University Hospital kn-affil=岡山大学病院　感染制御部 岡山大学病院　感染症内科 affil-num=4 en-affil=Section of Infection Control and Prevention, Okayama University Hospital kn-affil=岡山大学病院　感染制御部 岡山大学病院　小児科 en-keyword=疫学的調査 (epidemiological characteristics) kn-keyword=疫学的調査 (epidemiological characteristics) en-keyword=岡山 (Okayama Prefecture) kn-keyword=岡山 (Okayama Prefecture) en-keyword=新型コロナウイルス感染症 (COVID-19) kn-keyword=新型コロナウイルス感染症 (COVID-19) en-keyword=PCR検査 (PCR testing) kn-keyword=PCR検査 (PCR testing) en-keyword=SARS-CoV-2 kn-keyword=SARS-CoV-2 END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=1 article-no= start-page=123 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210421 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Integrated pulmonary index can predict respiratory compromise in high-risk patients in the post-anesthesia care unit: a prospective, observational study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Respiratory compromise (RC) including hypoxia and hypoventilation is likely to be missed in the postoperative period. Integrated pulmonary index (IPI) is a comprehensive respiratory parameter evaluating ventilation and oxygenation. It is calculated from four parameters: end-tidal carbon dioxide, respiratory rate, oxygen saturation measured by pulse oximetry (SpO(2)), and pulse rate. We hypothesized that IPI monitoring can help predict the occurrence of RC in patients at high-risk of hypoventilation in post-anesthesia care units (PACUs).
Methods: This prospective observational study was conducted in two centers and included older adults (>= 75-year-old) or obese (body mass index >= 28) patients who were at high-risk of hypoventilation. Monitoring was started on admission to the PACU after elective surgery under general anesthesia. We investigated the onset of RC defined as respiratory events with prolonged stay in the PACU or transfer to the intensive care units; airway narrowing, hypoxemia, hypercapnia, wheezing, apnea, and any other events that were judged to require interventions. We evaluated the relationship between several initial parameters in the PACU and the occurrence of RC. Additionally, we analyzed the relationship between IPI fluctuation during PACU stay and the occurrences of RC using individual standard deviations of the IPI every five minutes (IPI-SDs).
Results: In total, 288 patients were included (199 elderly, 66 obese, and 23 elderly and obese). Among them, 18 patients (6.3 %) developed RC. The initial IPI and SpO(2) values in the PACU in the RC group were significantly lower than those in the non-RC group (6.7 +/- 2.5 vs. 9.0 +/- 1.3, p < 0.001 and 95.9 +/- 4.2 % vs. 98.3 +/- 1.9 %, p = 0.040, respectively). We used the area under the receiver operating characteristic curves (AUC) to evaluate their ability to predict RC. The AUCs of the IPI and SpO(2) were 0.80 (0.69-0.91) and 0.64 (0.48-0.80), respectively. The IPI-SD, evaluating fluctuation, was significantly greater in the RC group than in the non-RC group (1.47 +/- 0.74 vs. 0.93 +/- 0.74, p = 0.002).
Conclusions: Our study showed that low value of the initial IPI and the fluctuating IPI after admission to the PACU predict the occurrence of RC. The IPI might be useful for respiratory monitoring in PACUs and ICUs after general anesthesia. en-copyright= kn-copyright= en-aut-name=KuroeYasutoshi en-aut-sei=Kuroe en-aut-mei=Yasutoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiharaYuko en-aut-sei=Mihara en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkaharaShuji en-aut-sei=Okahara en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshiiKenzo en-aut-sei=Ishii en-aut-mei=Kenzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KanazawaTomoyuki en-aut-sei=Kanazawa en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Resuscitology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Resuscitology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Anesthesiology and Resuscitology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Anesthesiology and Oncological Pain Medicine, Fukuyama City Hospital kn-affil= affil-num=5 en-affil=Department of Pediatric Anesthesiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Anesthesiology and Resuscitology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Integrated pulmonary index kn-keyword=Integrated pulmonary index en-keyword=Respiratory compromise kn-keyword=Respiratory compromise en-keyword=Post‐anesthesia care unit kn-keyword=Post‐anesthesia care unit END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=2 article-no= start-page=225 end-page=230 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=Histological Analysis of Repaired Tissue after Pullout Repair of a Medial Meniscus Posterior Root Tear en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 65-year-old man presented with a left medial meniscus (MM) posterior root tear (PRT). Unicompartmental knee arthroplasty was performed 12 months after transtibial pullout repair of the MMPRT. Repaired MM posterior root tissue was subjected to histological analysis. Immunostaining and picrosirius red staining showed sufficient deposition of type I collagen, and hematoxylin-eosin staining using a polarized microscope showed well-aligned fiber orientation in the repaired tissue. The repaired posterior root (post-transtibial pullout repair) showed mature and well-aligned ligament-like tissue. Preserving the MM posterior root remnant to mimic the original posterior root tissue might be useful when performing pullout repair. en-copyright= kn-copyright= en-aut-name=XueHaowei en-aut-sei=Xue en-aut-mei=Haowei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiranakaTakaaki en-aut-sei=Hiranaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KintakaKeisuke en-aut-sei=Kintaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ZhangXiming en-aut-sei=Zhang en-aut-mei=Ximing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshidaAki en-aut-sei=Yoshida en-aut-mei=Aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=medial meniscus kn-keyword=medial meniscus en-keyword=posterior root tear kn-keyword=posterior root tear en-keyword=unicompartmental knee arthroplasty kn-keyword=unicompartmental knee arthroplasty en-keyword=histological analysis kn-keyword=histological analysis en-keyword=case report kn-keyword=case report END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=2 article-no= start-page=187 end-page=197 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=Multiacquisition Variable-Resonance Image Combination Selective Can Improve Image Quality and Reproducibility for Metallic Implants in the Lumbar Spine en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study is to evaluate how metallic artifacts in the lumbar spine can affect images obtained from magnetic resonance (MR) sequences. We performed a phantom experiment by scanning an agar containing an orthopedic metallic implant using 64-channel multidetector row computed tomography (CT) and a 3-tesla MR unit. We compared the reproducibility in each measurement, enlargement or reduction ratio of the CT and MR measurements, and signal deviation in each voxel from the control. The reproducibility on CT and multiacquisition variable-resonance image combination selective (MAVRIC SL) was good, but that on the other MR sequences showed either fixed bias or proportional bias. The reduction ratios of the distance between the nails were significantly smaller in MAVRIC SL than in the other MR sequences after CT measurements (p<0.001, respectively). MAVRIC SL was able to reduce the metallic artifact, permitting observation of the tissue surrounding the metal with good reproducibility. en-copyright= kn-copyright= en-aut-name=FujiwaraYuta en-aut-sei=Fujiwara en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SasakiTomoaki en-aut-sei=Sasaki en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MutoYuki en-aut-sei=Muto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiranoMasaki en-aut-sei=Hirano en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KamizakiRyo en-aut-sei=Kamizaki en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MurakamiKaito en-aut-sei=Murakami en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiuraNaoya en-aut-sei=Miura en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujibuchiYutaka en-aut-sei=Fujibuchi en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OhmukaiNayu en-aut-sei=Ohmukai en-aut-mei=Nayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=UedaNao en-aut-sei=Ueda en-aut-mei=Nao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SugimotoKouhei en-aut-sei=Sugimoto en-aut-mei=Kouhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OtaKazuhiro en-aut-sei=Ota en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=KamihoriuchiYoshiki en-aut-sei=Kamihoriuchi en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=SasakiTomoko en-aut-sei=Sasaki en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=KaneshigeSouichirou en-aut-sei=Kaneshige en-aut-mei=Souichirou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Division of Clinical Radiology Service, Okayama Central Hospital kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=12 en-affil=Division of Clinical Radiology Service, Okayama Central Hospital kn-affil= affil-num=13 en-affil=Division of Clinical Radiology Service, Okayama Central Hospital kn-affil= affil-num=14 en-affil=Division of Clinical Radiology Service, Okayama Central Hospital kn-affil= affil-num=15 en-affil=Department of Radiology, Okayama Central Hospital kn-affil= en-keyword=metallic artifact reduction kn-keyword=metallic artifact reduction en-keyword=implant kn-keyword=implant en-keyword=MAVRIC SL kn-keyword=MAVRIC SL END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=2 article-no= start-page=147 end-page=152 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Knee Flexion-induced Translation of Pullout Sutures Used in the Repair of Medial Meniscus Posterior Root Tears en-subtitle= kn-subtitle= en-abstract= kn-abstract=Medial meniscus posterior root tears (MMPRTs) have recently attracted considerable interest in orthopedics. To date, no in vivo human study has investigated suture translation changes in repaired MMPRTs with different degrees of knee flexion. This study examined suture translation at various degrees of knee flexion in 30 patients undergoing medial meniscus posterior root repair using the modified Mason-Allen suture technique between August 2016 and September 2017. Intraoperatively, sutures were provisionally fixed to an isometric positioner at the tibial site of the desired meniscal attachment, and the suture translation was measured at 0°, 30°, 60°, and 90° of knee flexion. The results showed significant increases in mean suture translation at the knee flexion positions from 0° to 30°, 30° to 60°, and 60° to 90° (p<0.01 for all).

The absorbing peaks in the frequency band below 1000 Hz are shown to be multiplexed not only by simple superposition of vibrational modes of each layer, but also by hybridization of the modes indicating collective motion of tubes. en-copyright= kn-copyright= en-aut-name=TakasugiShota en-aut-sei=Takasugi en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WatanabeKeita en-aut-sei=Watanabe en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MisawaMasaaki en-aut-sei=Misawa en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsurutaKenji en-aut-sei=Tsuruta en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Electrical and Electronic Engineering, Okayama University kn-affil= affil-num=2 en-affil=Department of Electrical and Electronic Engineering, Okayama University kn-affil= affil-num=3 en-affil=Department of Electrical and Electronic Engineering, Okayama University kn-affil= affil-num=4 en-affil=Department of Electrical and Electronic Engineering, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=1 article-no= start-page=95 end-page=101 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202102 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Minimally Invasive Spinal Stabilization with Denosumab before Total Spondylectomy for a Collapsing Lower Lumbar Spinal Giant Cell Tumor en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 21-year-old man consulted our hospital for treatment of a spinal giant cell tumor (GCT) of Enneking stage III.

He was also on a low-carbohydrate diet that promoted ketosis under sodium glucose cotransporter 2 (SGLT2) inhibitor administration. Polyacrylamide gel electrophoresis revealed a remarkable increase in very-low-den-sity lipoprotein, a TG-rich lipoprotein particle synthesized in the liver using free fatty acids derived from adi-pose tissue. Although SGLT2 inhibitors generally improve the lipid profile, under certain conditions such as a low-carbohydrate diet, they may adversely exacerbate the lipid profile via ketosis. en-copyright= kn-copyright= en-aut-name=SenooMayumi en-aut-sei=Senoo en-aut-mei=Mayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ToneAtsuhito en-aut-sei=Tone en-aut-mei=Atsuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ImaiYusuke en-aut-sei=Imai en-aut-mei=Yusuke 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=KanetoMitsuhiro en-aut-sei=Kaneto en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShimomuraYasuyuki en-aut-sei=Shimomura en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TeshigawaraSanae en-aut-sei=Teshigawara en-aut-mei=Sanae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakatouTatsuaki en-aut-sei=Nakatou en-aut-mei=Tatsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Internal Medicine, Diabetes Center, Okayama Saiseikai General Hospital kn-affil= affil-num=2 en-affil=Department of Internal Medicine, Diabetes Center, Okayama Saiseikai General Hospital kn-affil= affil-num=3 en-affil=Department of Internal Medicine, Diabetes Center, Okayama Saiseikai General Hospital kn-affil= affil-num=4 en-affil=Department of Internal Medicine, Diabetes Center, Okayama Saiseikai General Hospital kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Diabetes Center, Okayama Saiseikai General Hospital kn-affil= affil-num=6 en-affil=Department of Internal Medicine, Diabetes Center, Okayama Saiseikai General Hospital kn-affil= affil-num=7 en-affil=Department of Internal Medicine, Diabetes Center, Okayama Saiseikai General Hospital kn-affil= affil-num=8 en-affil=Department of Internal Medicine, Diabetes Center, Okayama Saiseikai General Hospital kn-affil= en-keyword=sodium glucose cotransporter 2 inhibitor kn-keyword=sodium glucose cotransporter 2 inhibitor en-keyword=dyslipidemia kn-keyword=dyslipidemia en-keyword=hypertriglyceridemia kn-keyword=hypertriglyceridemia en-keyword=type 2 diabetes mellitus kn-keyword=type 2 diabetes mellitus END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=1 article-no= start-page=55 end-page=61 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202102 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Thoracoscopic Localization of Small Peripheral Pulmonary Lesions Using Percutaneous Computed Tomography-guided Pleural Dye Marking: A Retrospective Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Small pulmonary lesions are often difficult to localize during thoracoscopic surgery. We describe a new com-puted tomography (CT)-guided pleural dye-marking method for small peripheral pulmonary lesions that does not involve a visceral pleural puncture. We used this technique for 23 lesions (22 patients) who underwent tho-racoscopic partial lung resection (Nov. 2016-Jan. 2018). With the patient in the lateral decubitus position, pre-operative CT-guided marking on the skin over the lesion was performed. During the surgery, we marked the visceral pleura with a skin marker directly or with an infant-size nutrition catheter with crystal violet at the tip through a venous indwelling needle inserted perpendicular to the skin marking. We localized and resected the lesions in all cases, without complications. The median nodule size measured histopathologically was 8 (4-20) mm overall, and 7 (0-20) mm of the solid part; the median distance from the visceral pleura to the nodule was 9 (1-33) mm. The median operation time was 67 (37-180) min. The median postoperative hospital stay was 3 (3-11) days. Our CT-guided pleural dye-marking method is useful and safe for the localization of small periph-eral pulmonary lesions in thoracoscopic partial lung resections. en-copyright= kn-copyright= en-aut-name=KuboYujiro en-aut-sei=Kubo en-aut-mei=Yujiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WatanabeMototsugu en-aut-sei=Watanabe en-aut-mei=Mototsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ChoshiHaruki en-aut-sei=Choshi en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsubaraKei en-aut-sei=Matsubara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShiotaniToshio en-aut-sei=Shiotani en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KataokaKazuhiko en-aut-sei=Kataoka en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Thoracic Surgery, Iwakuni Clinical Center kn-affil= affil-num=2 en-affil=Department of Thoracic Surgery, Iwakuni Clinical Center kn-affil= affil-num=3 en-affil=Department of Thoracic Surgery, Iwakuni Clinical Center kn-affil= affil-num=4 en-affil=Department of Thoracic Surgery, Iwakuni Clinical Center kn-affil= affil-num=5 en-affil=Department of Thoracic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Thoracic Surgery, Iwakuni Clinical Center kn-affil= en-keyword=Small pulmonary lesion kn-keyword=Small pulmonary lesion en-keyword=ground glass nodule kn-keyword=ground glass nodule en-keyword=marking kn-keyword=marking en-keyword=localization kn-keyword=localization en-keyword=thoracocentesis kn-keyword=thoracocentesis END start-ver=1.4 cd-journal=joma no-vol=147 cd-vols= no-issue=1 article-no= start-page=107 end-page=124 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Phos-tag-based approach to study protein phosphorylation in the thylakoid membrane en-subtitle= kn-subtitle= en-abstract= kn-abstract=Protein phosphorylation is a fundamental post-translational modification in all organisms. In photoautotrophic organisms, protein phosphorylation is essential for the fine-tuning of photosynthesis. The reversible phosphorylation of the photosystem II (PSII) core and the light-harvesting complex of PSII (LHCII) contribute to the regulation of photosynthetic activities. Besides the phosphorylation of these major proteins, recent phosphoproteomic analyses have revealed that several proteins are phosphorylated in the thylakoid membrane. In this study, we utilized the Phos-tag technology for a comprehensive assessment of protein phosphorylation in the thylakoid membrane of Arabidopsis. Phos-tag SDS-PAGE enables the mobility shift of phosphorylated proteins compared with their non-phosphorylated isoform, thus differentiating phosphorylated proteins from their non-phosphorylated isoforms. We extrapolated this technique to two-dimensional (2D) SDS-PAGE for detecting protein phosphorylation in the thylakoid membrane. Thylakoid proteins were separated in the first dimension by conventional SDS-PAGE and in the second dimension by Phos-tag SDS-PAGE. In addition to the isolation of major phosphorylated photosynthesis-related proteins, 2D Phos-tag SDS-PAGE enabled the detection of several minor phosphorylated proteins in the thylakoid membrane. The analysis of the thylakoid kinase mutants demonstrated that light-dependent protein phosphorylation was mainly restricted to the phosphorylation of the PSII core and LHCII proteins. Furthermore, we assessed the phosphorylation states of the structural domains of the thylakoid membrane, grana core, grana margin, and stroma lamella. Overall, these results demonstrated that Phos-tag SDS-PAGE is a useful biochemical tool for studying in vivo protein phosphorylation in the thylakoid membrane protein. en-copyright= kn-copyright= en-aut-name=NishiokaKeiji en-aut-sei=Nishioka en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatoYusuke en-aut-sei=Kato en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OzawaShin-ichiro en-aut-sei=Ozawa en-aut-mei=Shin-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakahashiYuichiro en-aut-sei=Takahashi en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakamotoWataru en-aut-sei=Sakamoto en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= en-keyword=Chloroplast kn-keyword=Chloroplast en-keyword=Phos-tag kn-keyword=Phos-tag en-keyword=Protein phosphorylation kn-keyword=Protein phosphorylation en-keyword=Thylakoid membrane kn-keyword=Thylakoid membrane en-keyword=STN7 kn-keyword=STN7 en-keyword=STN8 kn-keyword=STN8 END start-ver=1.4 cd-journal=joma no-vol=60 cd-vols= no-issue=1 article-no= start-page=1 end-page=6 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=2020 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Hemosiderin deposition in lymph nodes of patients with plasma cell-type Castleman disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Plasma cell-type Castleman disease (PCD) is a rare idiopathic atypical lymphoproliferative disorder. It is difficult to differentiate between PCD and IgG4-related disease (IgG4-RD) based on histology alone. As PCD often presents with abundant hemosiderin deposition, lymph node lesions obtained from 22 PCD patients and 12 IgG4-RD patients were analyzed using Prussian blue staining to clarify whether hemosiderin deposition is effective in distinguishing between these two diseases. The analysis disclosed that hemosiderin was more densely deposited in PCD than in IgG4-RD. The median number of Prussian blue-positive cells ± standard deviation (SD) in PCD and IgG4-RD cases was 13 ± 36 cells/3HPFs and 4 ± 8 cells/3HPFs (P = 0.034), respectively. In addition, we analyzed the relationship between hemosiderin deposition and levels of serum interleukin (IL)-6, serum C-reactive protein (CRP), and anemia-related biomarkers. We found that hemosiderin deposition was significantly correlated with the level of serum CRP (P = 0.045); however, no significant correlation was observed between hemosiderin deposition and serum IL-6 levels (P = 0.204). A non-significant positive correlation was observed between hemosiderin deposition and serum hemoglobin levels (P=0.09). Furthermore, no significant correlation was observed between hemosiderin deposition and serum iron levels (P = 0.799). In conclusion, hemosiderin deposition characteristically observed in PCD may be related to the inflammatory aggressiveness of the disease and could be used for its differential diagnosis. en-copyright= kn-copyright= en-aut-name=HanYanyan en-aut-sei=Han en-aut-mei=Yanyan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IgawaTakuro en-aut-sei=Igawa en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OginoKyohei en-aut-sei=Ogino en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishikoriAsami en-aut-sei=Nishikori en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GionYuka en-aut-sei=Gion en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pathology, Fukuyama City Hospital kn-affil= affil-num=4 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=6 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= en-keyword=hemosiderin deposition kn-keyword=hemosiderin deposition en-keyword=plasma cell-type Castleman disease kn-keyword=plasma cell-type Castleman disease en-keyword=IgG4-related disease kn-keyword=IgG4-related disease en-keyword=serum IL-6 kn-keyword=serum IL-6 en-keyword=serum C-reactive protein kn-keyword=serum C-reactive protein END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=6 article-no= start-page=495 end-page=503 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Antenatal Care Visits and Adverse Pregnancy Outcomes at a Hospital in Rural Western Province, Rwanda en-subtitle= kn-subtitle= en-abstract= kn-abstract=In many economically developing countries, and especially in the rural regions of sub-Saharan African coun-tries, there have been only limited investigations into the association between antenatal care (ANC) and adverse pregnancy outcomes. We obtained information on ANC and pregnancy outcomes between 2011 and 2016 from hospital files of pregnant women (n = 4,960) served at a rural hospital in Rwanda, and we examined the associa-tions between their ANC visits and the adverse pregnancy and neonatal outcomes by using univariate and mul-tivariate logistic regression models to estimate the odds ratios (ORs) and 95% confidence intervals (CIs). Most of the pregnant women had ? 4 ANC visits, but 39% (n = 1,911) did not have ? 3 visits before delivery. The prev-alence of low birth weight (LBW) and that of preterm birth (PTB) were 12% and 9.9%, respectively. Compared to the women who attended only one ANC visit, those who attended ? 4 ANC visits had lower risks of LBW (OR 0.20; 95%CI: 0.11-0.36) and PTB (OR 0.28; 95%CI: 0.11-0.76). Frequent ANC visits were also associ-ated with better postnatal outcomes of the newborns. Encouraging women to attend ANC visits before delivery can markedly reduce PTB-related and LBW-related complications, especially in resource-limited settings. en-copyright= kn-copyright= en-aut-name=CalliopeSimba Akintije en-aut-sei=Calliope en-aut-mei=Simba Akintije kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=WadaTakayuki en-aut-sei=Wada en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MukakarakeMarie Goret en-aut-sei=Mukakarake en-aut-mei=Marie Goret kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MutesaLeon en-aut-sei=Mutesa en-aut-mei=Leon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamamotoTaro en-aut-sei=Yamamoto en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of International Health and Medical Anthropology, Institute of Tropical Medicine, Nagasaki University kn-affil= affil-num=2 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Graduate School of Human Life Science, Osaka City University kn-affil= affil-num=4 en-affil=Mibilizi District Hospital kn-affil= affil-num=5 en-affil=Center for Human Genetics, College of Medicine and Health Sciences, University of Rwanda kn-affil= affil-num=6 en-affil=Department of International Health and Medical Anthropology, Institute of Tropical Medicine, Nagasaki University kn-affil= en-keyword=antenatal care kn-keyword=antenatal care en-keyword=epidemiology kn-keyword=epidemiology en-keyword=low birth weight kn-keyword=low birth weight en-keyword=preterm birth kn-keyword=preterm birth en-keyword=rural kn-keyword=rural END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=6 article-no= start-page=483 end-page=493 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Potential of Artificial Intelligence for Estimating Japanese Fetal Weights en-subtitle= kn-subtitle= en-abstract= kn-abstract=We developed an artificial intelligence (AI) method for estimating fetal weights of Japanese fetuses based on the gestational weeks and the bi-parietal diameter, abdominal circumference, and femur length. The AI comprised of neural network architecture was trained by deep learning with a dataset that consists of ± 2 standard devia-tion (SD), ± 1.5SD, and ± 0SD categories of the approved standard values of ultrasonic measurements of the fetal weights of Japanese fetuses (Japan Society of Ultrasonics in Medicine [JSUM] data). We investigated the residuals and compared 2 other regression formulae for estimating the fetal weights of Japanese fetuses by t-test and Bland-Altman analyses, respectively. The residuals of the AI for the test dataset that was 12.5% of the JSUM data were 6.4 ± 2.6, ?3.8 ± 8.6, and ?0.32 ± 6.3 (g) at ?2SD, +2SD, and all categories, respectively. The residu-als of another AI method created with all of the JSUM data, of which 20% were randomized validation data, were ?1.5 ± 9.4, ?2.5 ± 7.3, and ?1.1 ± 6.7 (g) for ?2SD, +2SD, and all categories, respectively. The residuals of this AI were not different from zero, whereas those of the published formulae differed from zero. Though vali-dation is required, the AI demonstrated potential for generating fetal weights accurately, especially for extreme fetal weights. en-copyright= kn-copyright= en-aut-name=MiyagiYasunari en-aut-sei=Miyagi en-aut-mei=Yasunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyakeTakahito en-aut-sei=Miyake en-aut-mei=Takahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Medical Data Labo kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Miyake Clinic kn-affil= en-keyword=deep learning kn-keyword=deep learning en-keyword=artificial intelligence kn-keyword=artificial intelligence en-keyword=fetal weight kn-keyword=fetal weight en-keyword=neural network kn-keyword=neural network en-keyword=ultrasound biometry kn-keyword=ultrasound biometry END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=6 article-no= start-page=467 end-page=474 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical Application of the Ratio of Serum Bone Isoform to Total Alkaline Phosphatase in General Practice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Alkaline phosphatase (ALP) is an enzyme that is expressed in a variety of tissues. Among the isoforms of ALP, bone-specific alkaline phosphatase (BAP) is used as a marker for evaluating bone metabolism. We investigated the clinical usefulness of the ratio of serum BAP to total ALP for the diagnosis of various disorders in general practice. We retrospectively analyzed the cases of 107 Japanese patients whose serum BAP levels were exam-ined, focusing on clinical characteristics. We observed that the BAP/ALP ratios of the patients with fever and those with inflammatory diseases were significantly lower than the ratios of other patient groups. The BAP/ALP ratios of the patients with osteoporosis and those with metabolic bone diseases were higher than those of the patients with other conditions. The BAP/ALP ratio was found to be negatively correlated with age, a cor-relation that has not been found in other ethnicities. The serum BAP/ALP ratio was inversely correlated with serum CRP levels but was positively correlated with serum albumin levels and hemoglobin concentrations. Collectively, our results suggest that the BAP/ALP ratio could be a useful predictor for important geriatric con-ditions seen in general practice. en-copyright= kn-copyright= en-aut-name=YokotaYuya en-aut-sei=Yokota en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AndoAkemi en-aut-sei=Ando en-aut-mei=Akemi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HanayamaYoshihisa en-aut-sei=Hanayama en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HasegawaKou en-aut-sei=Hasegawa en-aut-mei=Kou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=OgawaHiroko en-aut-sei=Ogawa en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ObikaMikako en-aut-sei=Obika en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UedaKeigo en-aut-sei=Ueda en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=alkaline phosphatase kn-keyword=alkaline phosphatase en-keyword=BAP kn-keyword=BAP en-keyword=CRP kn-keyword=CRP en-keyword=inflammation kn-keyword=inflammation en-keyword=osteoporosis kn-keyword=osteoporosis END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=1 article-no= start-page=18715 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201030 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Risk of higher dose methotrexate for renal impairment in patients with rheumatoid arthritis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Renal impairment is a major concern in patients taking high-dose methotrexate (MTX) for malignancy, but it has not been fully explored in rheumatoid arthritis (RA) patients taking low-dose MTX. This study aimed to elucidate the dose-dependent effects of MTX on the renal function of patients with RA. We retrospectively reviewed 502 consecutive RA patients who were prescribed MTX for >= 1 year at Okayama University Hospital between 2006 and 2018. The primary outcome was the change in estimated glomerular filtration rate (eGFR) over 1 year. The association between MTX dosage (<8, 8-12, and >= 12 mg/week) and the change in eGFR was evaluated using multiple linear regression analysis with adjustment for possible confounding factors including age, sex, disease duration, body weight, comorbidity, baseline eGFR, concomitant treatment, and disease activity. Mean patient age was 63 years; 394 (78%) were female. Median disease duration was 77 months, while mean MTX dosage was 8.6 mg/week. The last 1-year change of eGFR (mean +/- SD) in patients treated with MTX<8 (n=186), 8-12 (n=219),>= 12 mg/week (n=97) decreased by 0.2 +/- 7.3, 0.6 +/- 8.6, and 4.5 +/- 7.9 mL/min/1.73 m(2)/year, respectively (p<0.0001). After adjustment for the confounding factors, MTX >= 12 mg/week was still correlated with a decrease in 1-year eGFR (beta-coefficient:-2.5; 95% confidence interval,-4.3 to-0.6; p=0.0089) in contrast to MTX 8-12 mg/week. Careful monitoring of renal function is required in patients with MTX >= 12 mg/week over the course of RA treatment regardless of disease duration. en-copyright= kn-copyright= en-aut-name=HayashiKeigo en-aut-sei=Hayashi en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SadaKen-Ei en-aut-sei=Sada en-aut-mei=Ken-Ei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AsanoYosuke en-aut-sei=Asano en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name= Hiramatsu AsanoSumie en-aut-sei= Hiramatsu Asano en-aut-mei=Sumie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamuraYuriko en-aut-sei=Yamamura en-aut-mei=Yuriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhashiKeiji en-aut-sei=Ohashi en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MorishitaMichiko en-aut-sei=Morishita en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeHaruki en-aut-sei=Watanabe en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NarazakiMariko en-aut-sei=Narazaki en-aut-mei=Mariko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsumotoYoshinori en-aut-sei=Matsumoto en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Nephrology kn-keyword=Nephrology en-keyword=Rheumatology kn-keyword=Rheumatology END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=5 article-no= start-page=381 end-page=389 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202010 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical Relevance of Serum Prolactin Levels to Inflammatory Reaction in Male Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=To clarify the relevance of prolactin (PRL) to clinical parameters in patients who visited our general medicine department, medical records of 353 patients in whom serum PRL levels were measured during the period from 2016 to 2018 were retrospectively reviewed. Data for 140 patients (M/F: 42/98) were analyzed after excluding patients lacking detailed records and patients taking dopaminergic agents. Median serum PRL levels were significantly lower in males than females: 6.5 ng/ml (IQR: 4.2-10.3) versus 8.1 ng/ml (5.9-12.9), respectively. Pain and general fatigue were the major symptoms at the first visit, and past histories of hypertension and dyslipidemia were frequent. Male patients with relatively high PRL levels (? 10 ng/ml) had significantly lower levels of serum albumin and significantly higher levels of serum LDH than those with low PRL (< 10 ng/ml). There were significant correlations of male PRL level with the erythrocyte sedimentation rate (R=0.62), serum LDH level (R=0.39) and serum albumin level (R=?0.52), while the level of serum CRP (R=0.33) showed an insignificant but weak positive correlation with PRL level. Collectively, these results show that PRL levels had gender-specific relevance to various clinical factors, with PRL levels in males being significantly related to inflammatory status. en-copyright= kn-copyright= en-aut-name=YamamotoKoichiro en-aut-sei=Yamamoto en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HanayamaYoshihisa en-aut-sei=Hanayama en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HasegawaKou en-aut-sei=Hasegawa en-aut-mei=Kou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TokumasuKazuki en-aut-sei=Tokumasu en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 ORCID= en-aut-name=OgawaHiroko en-aut-sei=Ogawa en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ObikaMikako en-aut-sei=Obika en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ItoshimaKoichi en-aut-sei=Itoshima en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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= affil-num=9 en-affil=Department of Laboratory Medicine, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=hormones kn-keyword=hormones en-keyword=hyperprolactinemia kn-keyword=hyperprolactinemia en-keyword=inflammation kn-keyword=inflammation en-keyword=pituitary kn-keyword=pituitary en-keyword=prolactin kn-keyword=prolactin END start-ver=1.4 cd-journal=joma no-vol=325 cd-vols= no-issue= article-no= start-page=108645 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200716 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Isolation and identification of the antimicrobial substance included in tempeh using Rhizopus stolonifer NBRC 30816 for fermentation en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, we focus on the antimicrobial properties of tempeh, a soybean fermented food, against oral bacteria.
Tempeh showed antimicrobial activity against dental caries pathogenic bacterium Streptococcus mutans at a final concentration of 1 mg/mL. An antimicrobial substance contained in tempeh was present in the 100 kDa or greater fraction generated by ultrafiltration, but it was found not to be proteinaceous by native-PAGE, SDS-PAGE and protein degradation tests. Next, when the fraction was purified with an ODS column, the 80% and 100% methanol eluates showed antimicrobial activity against S. mutans. The 100% methanol eluate was further subjected to a 2nd column purification, and isolation of the target was confirmed by HPLC. When the isolated material was analyzed by ESI-MS, the m/z was 279.234. Further analysis by Raman spectroscopy revealed a peak similar to linoleic acid. This substance also possessed antimicrobial properties equivalent to linoleic acid. en-copyright= kn-copyright= en-aut-name=ItoMasahiro en-aut-sei=Ito en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ItoTakashi en-aut-sei=Ito en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AokiHideyuki en-aut-sei=Aoki en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishiokaKoshi en-aut-sei=Nishioka en-aut-mei=Koshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShiokawaTsugumi en-aut-sei=Shiokawa en-aut-mei=Tsugumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TadaHiroko en-aut-sei=Tada en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakeuchiYuki en-aut-sei=Takeuchi en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakeyasuNobuyuki en-aut-sei=Takeyasu en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamamotoTadashi en-aut-sei=Yamamoto en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Pathophysiology - Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathophysiology - Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Ikeda Food Research Co., Ltd. kn-affil= affil-num=4 en-affil=Ikeda Food Research Co., Ltd. kn-affil= affil-num=5 en-affil=Division of Instrumental Analysis, Department of Instrumental Analysis and Cryogenics, Advanced Science Research Center, Okayama University kn-affil= affil-num=6 en-affil=Division of Instrumental Analysis, Department of Instrumental Analysis and Cryogenics, Advanced Science Research Center, Okayama University kn-affil= affil-num=7 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Department of Pathophysiology - Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Pathophysiology - Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Fermented soybean food kn-keyword=Fermented soybean food en-keyword=Oral infection kn-keyword=Oral infection en-keyword=Antibacterial kn-keyword=Antibacterial en-keyword=Linoleic acid kn-keyword=Linoleic acid END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=4 article-no= start-page=335 end-page=343 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202008 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Recurrence of Solitary Fibrous Tumor/Hemangiopericytoma Could Be Predicted by Ki-67 Regardless of Its Origin en-subtitle= kn-subtitle= en-abstract= kn-abstract=Since the discovery of the NAB2-STAT6 gene fusion in 2013, solitary fibrous tumor (SFT) and hemangiopericytoma (HPC) have been considered the same disease. STAT6 nuclear stain is approved as a highly sensitive and specific marker to diagnose SFT/HPC from other tumors with similar histology. As the next step, detection of fusion variants that may predict clinical malignancy of SFT/HPC has been attempted. However, no fusion variants with a clear relation to malignancy have been identified. In this study, the clinical and histological backgrounds of 23 Japanese patients diagnosed with SFT/HPC from 2000 to 2019 at Kochi University Hospital were examined to identify factors potentially related to recurrence. A significant relationship to recurrence was detected for mitosis ? 1/10 HPF (400×), necrosis, and Ki-67>5%. These findings indicate that a deliberate investigation of histological features such as mitosis and necrosis is crucial for the clinical observation of SFT/ HPC patients.

Alcohol extracts from plastic wrap, i.e., polyvinylidene chloride (PVDC), showed cytotoxic effects on the cells. Alcohol extracts of polyethylene (PE) wrap were not toxic. The commercially available PVDC wrap consists of vinylidene chloride, epoxidized soybean oil, epoxidized linseed oil as a stiffener and stabilizer; we sought to identify which component(s) are toxic. The epoxidized soybean oil and epoxidized linseed oil exerted strong cytotoxicity, but the plastic raw material itself, vinylidene chloride, did not. Our findings indicate that plastic wraps should be used with caution in order to prevent health risks. en-copyright= kn-copyright= 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=1 ORCID= en-aut-name=KagawaHiroko en-aut-sei=Kagawa en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ArimotoSakae en-aut-sei=Arimoto en-aut-mei=Sakae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanXian Wen en-aut-sei=Tan en-aut-mei=Xian Wen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YasuiKento en-aut-sei=Yasui en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OshikiToshiyuki en-aut-sei=Oshiki en-aut-mei=Toshiyuki 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= affil-num=1 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Okayama University Hospital kn-affil= affil-num=3 en-affil=Division of Pharmaceutical Sciences, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cell Chemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=plastic wrap kn-keyword=plastic wrap en-keyword=plasticizer, kn-keyword=plasticizer, en-keyword=cytotoxicity, kn-keyword=cytotoxicity, en-keyword=liver cells kn-keyword=liver cells en-keyword=in vitro kn-keyword=in vitro END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=3 article-no= start-page=83 end-page=92 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200421 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Early Decline of alpha-Fetoprotein and Des-gamma-Carboxy Prothrombin Predicts the Response of Hepatic Arterial Infusion Chemotherapy in Hepatocellular Carcinoma Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Molecular targeting drugs are recommended as second-line treatment for intrahepatic advanced hepatocellular carcinoma (HCC). However, in Asia, hepatic arterial infusion chemotherapy (HAIC) is also considered as a second-line treatment because it improves the survival of responders. The aim of this study was to predict responders and non-responders to HAIC with low-dose cisplatin plus 5-fluorouracil (LFP) using tumor markers.
Objective and Methods: The data of 47 patients who received LFP for the first time in our hospital were analyzed retrospectively. We evaluated the association between treatment response by Response Evaluation Criteria in Solid Tumors and the changing ratio of the serum concentration of alpha-fetoprotein (AFP),Lens culinarisagglutinin-reactive fraction of AFP (AFP-L3), and des-gamma-carboxy prothrombin (DCP) 2 weeks after LFP initiation.
Results: The number of patients showing a complete response (CR), a partial response (PR), stable disease (SD), and progressive disease (PD) was 0 (0%), 20 (43%), 18 (38%), and 9 (19%), respectively. The AFP ratio showed significant positive correlations for PR vs. SD (p= 0.004) and PR vs. PD (p= 0.003). The DCP ratio correlated significantly for PR vs. SD (p= 0.02). The optimal cutoff values for responders were 0.79 for the AFP ratio and 0.53 for the DCP ratio. Prediction using both or either cutoff value showed 93% sensitivity, 53% specificity, a 94% negative predictive value, and a 57% positive predictive value.
Conclusion: Optimal cutoff values for AFP and DCP ratios enable prediction of nonresponders to HAIC with LFP. This simple and early assessment method allows the use of HAIC and molecular targeting drugs for HCC treatment. en-copyright= kn-copyright= en-aut-name=YamamotoShumpei en-aut-sei=Yamamoto en-aut-mei=Shumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OnishiHideki en-aut-sei=Onishi en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakakiAkinobu en-aut-sei=Takaki en-aut-mei=Akinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OyamaAtsushi en-aut-sei=Oyama en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AdachiTakuya en-aut-sei=Adachi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WadaNozomu en-aut-sei=Wada en-aut-mei=Nozomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakataMasahiro en-aut-sei=Sakata en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YasunakaTetsuya en-aut-sei=Yasunaka en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShirahaHidenori en-aut-sei=Shiraha en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Hepatocellular carcinoma kn-keyword=Hepatocellular carcinoma en-keyword=Hepatic arterial infusion chemotherapy kn-keyword=Hepatic arterial infusion chemotherapy en-keyword=Low-dose cisplatin plus 5-fluorouracil kn-keyword=Low-dose cisplatin plus 5-fluorouracil en-keyword=alpha-Fetoprotein kn-keyword=alpha-Fetoprotein en-keyword=Des-gamma-carboxy prothrombin kn-keyword=Des-gamma-carboxy prothrombin END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=3 article-no= start-page=209 end-page=214 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202006 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Clinical Study Evaluating an Aspiration-type Semi-Automatic Cutting Biopsy Needle (SCIRO-1702) en-subtitle= kn-subtitle= en-abstract= kn-abstract=An aspiration-type semi-automatic cutting biopsy needle enables tissue cutting during application of negative pressure, which is expected to contribute to a larger amount of specimen. The aim of the present study was to evaluate this novel needle in a clinical setting. Patients who underwent image-guided percutaneous biopsy for lung or renal masses were enrolled. Cutting biopsy was performed with and without aspiration during each procedure. The specimens were weighed using an electronic scale. The weights were compared between specimens obtained with and without aspiration using a paired t-test. The data from 45 lung and 30 renal biopsy procedures were analyzed. In lung biopsy, the mean±standard deviation weights of specimens obtained with and without aspiration were 2.20±1.05 mg and 2.24±1.08 mg, respectively. In renal biopsy, the mean weights were 6.52±2.18 mg and 6.42±1.62 mg, respectively. The weights were not significantly different between specimens obtained with and without aspiration either in lung (p=0.799) or renal (p=0.789) biopsies. The application of negative pressure with the aspiration-type semi-automatic cutting biopsy needle did not contribute to an increase in the amount of the specimen obtained in lung and renal biopsies. en-copyright= kn-copyright= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakuraiJun en-aut-sei=Sakurai en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UkaMayu en-aut-sei=Uka en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MasaokaYoshihisa en-aut-sei=Masaoka en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=GobaraHideo en-aut-sei=Gobara en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KanazawaSusumu en-aut-sei=Kanazawa en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Center for Innovative Clinical Medicine kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Division of Medical Informatics, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=biopsy kn-keyword=biopsy en-keyword=cutting needle kn-keyword=cutting needle en-keyword=aspiration kn-keyword=aspiration en-keyword=clinical study kn-keyword=clinical study END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=3 article-no= start-page=185 end-page=190 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202006 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Stem Cell Therapy in Heart Disease: Limitations and Future Possibilities en-subtitle= kn-subtitle= en-abstract= kn-abstract=Heart diseases are one of the major causes of morbidity and mortality worldwide. Despite major advances in drug and interventional therapies, surgical procedures, and organ transplantation, further research into new therapeutic options is still necessary. Stem cell therapy has emerged as one option for the treatment of a variety of heart diseases. Although a large number of clinical trials have shown stem cell therapy to be a promising therapeutic approach, the results obtained from these clinical studies are inconsistent, and stem cell-based improvements of heart performance and cardiac remodeling were found to be quite limited. Since the precise mechanisms underlying the therapeutic actions of stem cells are still under debate, researchers have developed a variety of strategies to improve and boost the potency of stem cells in repair. In this review, we summarize both the current therapeutic strategies using stem cells and future directions for enhancing stem cell potency. en-copyright= kn-copyright= en-aut-name=SanoToshikazu en-aut-sei=Sano en-aut-mei=Toshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshigamiShuta en-aut-sei=Ishigami en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ItoTatsuo en-aut-sei=Ito en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SanoShunji en-aut-sei=Sano en-aut-mei=Shunji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Surgery, Division of Pediatric Cardiothoracic Surgery, University of California San Francisco kn-affil= affil-num=2 en-affil=Department of Surgery, Division of Pediatric Cardiothoracic Surgery, University of California San Francisco kn-affil= affil-num=3 en-affil=Department of Hygiene, Kawasaki Medical University kn-affil= affil-num=4 en-affil=Department of Surgery, Division of Pediatric Cardiothoracic Surgery, University of California San Francisco kn-affil= en-keyword=heart disease kn-keyword=heart disease en-keyword=stem cell kn-keyword=stem cell en-keyword=myocardial regeneration kn-keyword=myocardial regeneration END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=4 article-no= start-page=e2797 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202004 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Utilization of a Simple Surgical Guide for Multidirectional Cranial Distraction Osteogenesis in Craniosynostosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Multidirectional cranial distraction osteogenesis (MCDO) can achieve a desired shape for deformities of the cranium. In the past, visual estimation was used to reflect on the actual skull, but it was time-consuming and inaccurate. Here we demonstrate an effective osteotomy navigation method using surgical guides made from a dental impression silicone.
Methods: Seven patients who underwent MCDO between August 2013 and September 2016 were included in the study. Five cases involved utilization of the surgical guide for osteotomy. Three-dimensional (3D) printed cranium models were made using 3D computed tomography (3DCT) imaging data and dental impression silicone sheets were molded using the printed cranium models. These surgical guides were sterilized and used for intraoperative osteotomy design. Vertical distance between nasion/porion and osteotomy lines were calculated using 3D printed cranial models and postoperative 3DCT images to assess reproducibility.
Results: The average surgical time/design time was 535/37.0 minutes for the nonsurgical guide group and 486.8/11.8 minutes for the surgical guide group (SG). Treatment using the surgical guide was significantly shorter in terms of operative time and time required for design. For the vertical distance comparison, the average distance was 5.7mm (SD = 0.3) in the non-SG and 2.5mm (SD = 0.44) in the SG, and SG was more accurate.
Conclusions: Shorter operative times and higher reproducibility rates could be achieved by using the proposed surgical guide, which is accurate, low-cost, and easily accessible. en-copyright= kn-copyright= en-aut-name=MatsuiChihiro en-aut-sei=Matsui en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TokuyamaEijiro en-aut-sei=Tokuyama en-aut-mei=Eijiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SenooTakaya en-aut-sei=Senoo en-aut-mei=Takaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=KamedaMasahiro en-aut-sei=Kameda en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakeuchiTetsuo en-aut-sei=Takeuchi en-aut-mei=Tetsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Department of Plastic and Reconstructive Surgery,Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Plastic and Reconstructive Surgery,Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Plastic and Reconstructive Surgery,Okayama University Hospital 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 Neurological Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Occlusal and Oral Functional Rehabilitation, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Plastic and Reconstructive Surgery,Okayama University Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol=257 cd-vols= no-issue= article-no= start-page=662 end-page=662 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190122 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Magnetic resonance imaging findings of age-related distance esotropia in Japanese patients with high myopia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose
This study aimed to investigate the characteristics of the extraocular muscles and the orbital connective tissue pulleys in Japanese patients with age-related distance esotropia (ARDE) and high myopia using magnetic resonance imaging (MRI).
Methods
This was a retrospective case-series study. High-resolution coronal MRI scans of 12 orbits were obtained in 6 patients with ARDE and high myopia (age range: 51?69 years). We analyzed the images to determine the positions of the rectus muscle pulleys relative to the center of the globe, the integrity of the lateral rectus-superior rectus muscle (LR-SR) band, and the LR angle (the angle between the major axis of the LR and the vertical plane).
Results
The distance esotropia ranged from 4 to 25?, and 3 cases exhibited vertical deviations. The mean (±standard deviation (SD)) axial length was 28.5 (± 1.6) mm. The mean positions of the medial rectus muscle pulley and LR pulley were 1.3 mm inferior and 1.4 mm inferior, respectively, to those seen in the normal control group in our previous study (P?=?0.002 and P?=?0.05, respectively). All 12 orbits had abnormal elongated LR-SR bands, and 8 orbits (67%) displayed ruptured LR-SR bands. The LR angle (mean±SD; 18.8°?±?8.5°) increased significantly with the inferior displacement of the LR pulley (R2?=?0.77, P?=?0.0002).
Conclusions
Inferior displacement of the LR pulley and abnormal LR-SR bands were seen in Japanese ARDE patients with high myopia, as was found in ARDE patients without high myopia. The LR angle might be useful for judging the degree of LR pulley displacement. en-copyright= kn-copyright= en-aut-name=KonoReika en-aut-sei=Kono en-aut-mei=Reika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhtsukiHiroshi en-aut-sei=Ohtsuki en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KishimotoFumiko en-aut-sei=Kishimoto en-aut-mei=Fumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HamasakiIchiro en-aut-sei=Hamasaki en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MorizaneYuki en-aut-sei=Morizane en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShiragaFumio en-aut-sei=Shiraga en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Medical School, Okayama University kn-affil= affil-num=2 en-affil=Division of Ophthalmology, Okayama Saiseikai General Hospital kn-affil= affil-num=3 en-affil=Division of Ophthalmology, Ibara City Hospital kn-affil= affil-num=4 en-affil=Department of Ophthalmology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=age-related distance esotropia kn-keyword=age-related distance esotropia en-keyword=esotropia kn-keyword=esotropia en-keyword=high myopia kn-keyword=high myopia en-keyword=orbital pulley kn-keyword=orbital pulley en-keyword=sagging eye syndrome kn-keyword=sagging eye syndrome END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=2 article-no= start-page=159 end-page=163 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202004 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Juvenile Granulosa Cell Tumor with an Unusual Clinical Course: A Late-onset and Late Recurrent Case en-subtitle= kn-subtitle= en-abstract= kn-abstract= Juvenile granulosa cell tumors (JGCTs) are rare ovarian tumors with overall good prognoses. They differ from adult granulosa cell tumors (AGCTs), which are well known for late recurrence. Most JGCTs (〜97%) occur in individuals <30 years old. We report a recurrent JGCT in a 40-year-old woman 5 years after initial presentation. The histological appearance and lack of 402C>G missense point mutation of FOXL2 gene (characteristic of AGCT but absent in JGCT) allowed differentiation from AGCT. This is the first comprehensive report of JGCT with late recurrence. Although rare, late recurrence of JGCT can occur; long-term surveillance is suggested. en-copyright= kn-copyright= en-aut-name=Thar Htet San en-aut-sei=Thar Htet San en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtaYoko en-aut-sei=Ota en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FushimiSoichiro en-aut-sei=Fushimi en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=YanaiHiroyuki en-aut-sei=Yanai en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TodaHiroko en-aut-sei=Toda en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KunitomoTadayoshi en-aut-sei=Kunitomo en-aut-mei=Tadayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KodamaKeisuke en-aut-sei=Kodama en-aut-mei=Keisuke 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, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pathology and Experimental Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pathology, Himeji Red Cross Hospital kn-affil= affil-num=4 en-affil=Department of Pathology and Experimental Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Section of Diagnostic Pathology, Fukuyama Medical Association kn-affil= affil-num=7 en-affil=Department of Pathology, Kurashiki Medical Center kn-affil= affil-num=8 en-affil=Department of Gynecology, Kurashiki Medical Center kn-affil= affil-num=9 en-affil=Department of Pathology and Experimental Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=juvenile granulosa cell tumor kn-keyword=juvenile granulosa cell tumor en-keyword=late recurrence kn-keyword=late recurrence en-keyword=adult granulosa cell tumor kn-keyword=adult granulosa cell tumor END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=2 article-no= start-page=129 end-page=135 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202004 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between Histological Types and Enhancement of Dynamic CT for Primary Lung Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract= The aim of this study was to explore enhancement patterns of different types of primary lung cancers on 2-phase dynamic computed tomography (CT). This study included 217 primary lung cancer patients (141 adenocarcinomas [ADs], 48 squamous cell carcinomas [SCCs], 20 small cell lung carcinomas [SCLCs], and 8 others) who were examined using a 2-phase dynamic scan. Regions of interest were identified and mean enhancement values were calculated. After excluding the 20 SCLCs because these lesions had different clinical stages from the other cancer types, the mean attenuation values and subtractions between phases were compared between types of non-small cell lung carcinomas (NSCLCs) using the Kruskal?Wallis test. Late phase attenuation and attenuation of the late minus unenhanced phase (LMU) of SCCs were significantly higher than those of ADs (p<0.05). To differentiate SCC and AD in the late phase, a threshold of 80.21 Hounsfield units (HU) gave 52.9% accuracy. In LMU, a threshold of 52.16 HU gave 59.3% accuracy. Dynamic lung CT has the potential to aid in differentiating among NSCLC types. en-copyright= kn-copyright= en-aut-name=FukumaShogo en-aut-sei=Fukuma en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShinyaTakayoshi en-aut-sei=Shinya en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SohJunichi en-aut-sei=Soh en-aut-mei=Junichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukuharaRyuichiro en-aut-sei=Fukuhara en-aut-mei=Ryuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OgawaNanako en-aut-sei=Ogawa en-aut-mei=Nanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=IchiharaEiki en-aut-sei=Ichihara en-aut-mei=Eiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KanazawaSusumu en-aut-sei=Kanazawa en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery, Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pediatric Radiology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Radiology, Okayama City General Medical Center kn-affil= affil-num=7 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of General Thoracic Surgery, Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Radiology, Okayama University Hospital kn-affil= en-keyword=differentiation kn-keyword=differentiation en-keyword=dynamic computed tomography kn-keyword=dynamic computed tomography en-keyword=primary lung cancer kn-keyword=primary lung cancer en-keyword=enhancement pattern kn-keyword=enhancement pattern END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=4 article-no= start-page=551 end-page=560 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190923 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Separation Between Silicon and Aluminum Powders Contained Within Pulverized Scraped Silicon-Based Waste Solar Cells by Flotation Method en-subtitle= kn-subtitle= en-abstract= kn-abstract= There are few study examples on the separation of metals by floating method. In this study, separation of silicon and aluminum, which are the main components of silicon-based solar cell module, was carried out by floating method in order to purify silicon from waste solar cell module. The selection of surfactant, control of electric charge, wettability of the solid particles, surface tensions, and bubble surface area are important for separation of solids by floating method. Sodium dodecyl sulfate (SDS) can increase the hydrophobicity of aluminum powder due to the difference of surface potentials between silicon and aluminum. SDS behaves as a collector of aluminum as well as a frothing agent to decrease the bubble size. At a SDS concentration of 2 g/L and sample dipping time of 10 min, 80.1 mass% of aluminum was floated and separated, and the sedimentary silicon reached a purity of 90.7% from a mixture of 50 mass% aluminum and 50 mass% silicon. Finally, at a pH value of 7.0, SDS concentration between 1.0 and 2.5 g/L and air flow rate of 2.5 L/min (STP) were suitable experimental conditions to purify silicon from a mixture of silicon and aluminum by flotation separation method. en-copyright= kn-copyright= en-aut-name=HaradaSho en-aut-sei=Harada en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UddinMd.

We used the data obtained from a large-scale population-based representative database of health insurance claims in a single prefecture in Japan. We examined all of the outpatient and pharmaceutical health insurance claims for National Health Insurance and those for Late-stage Elderly Health Insurance in Nagasaki Prefecture, Japan between April and June 2016. When two or more claim forms were issued for a patient in a single month, we combined the data and identified the number of prescribed drugs for each person. The definition of polypharmacy is a the prescription of six or more drugs per month. We investigated the prevalence of polypharmacy among the beneficiaries of the two insurance systems. Of the 605,406 beneficiaries of the 2 insurance systems, 121,033 (20.0%) patients with polypharmacy were identified. The prevalence of polypharmacy increased with age, especially among the beneficiaries aged > 85 years, with about half of the beneficiaries having polypharmacy status. About half of the people aged > 85 years in the database had polypharmacy status. When a drug is prescribed to an elderly individual, it is necessary to consider the possibility of polypharmacy-related problems. en-copyright= kn-copyright= en-aut-name=AmanoHoichi en-aut-sei=Amano en-aut-mei=Hoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujimotoKenichi en-aut-sei=Fujimoto en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujimoriMakoto en-aut-sei=Fujimori en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakaNatsumi en-aut-sei=Saka en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NomuraKyoko en-aut-sei=Nomura en-aut-mei=Kyoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TaniharaShinichi en-aut-sei=Tanihara en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Public Health, Teikyo University kn-affil= affil-num=2 en-affil=Graduate School of Public Health, Teikyo University kn-affil= affil-num=3 en-affil=Graduate School of Public Health, Teikyo University kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Teikyo University School of Medicine kn-affil= affil-num=5 en-affil=Graduate School of Public Health, Teikyo University kn-affil= affil-num=6 en-affil=Graduate School of Public Health, Teikyo University kn-affil= en-keyword=health insurance claims kn-keyword=health insurance claims en-keyword=late-stage elderly health insurance kn-keyword=late-stage elderly health insurance en-keyword=national health insurance kn-keyword=national health insurance en-keyword=Japan kn-keyword=Japan en-keyword=polypharmacy kn-keyword=polypharmacy END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=1 article-no= start-page=33 end-page=40 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202002 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical Relevance of Blood Glucose and Gastroesophageal Reflux Symptoms to Depressive Status in Patients with Type 2 Diabetes Mellitus en-subtitle= kn-subtitle= en-abstract= kn-abstract= A relationship between diabetes and depression is apparent. To clarify the clinical relevance of diabetic patients’ gastroesophageal symptoms to their psychological status, we retrospectively analyzed the data from a Selfrating Depression Scale (SDS) and a Frequency Scale for Symptoms of Gastroesophageal reflux disease (FSSG) among 143 type 2 diabetic patients who visited a general medicine department. Among the 45 Japanese patients enrolled, the group with relatively high SDS scores (? 36) showed higher (FSSG) dysmotility symptom scores versus the low-SDS (< 36) group, although the 2 groups’ characteristics and laboratory data were not significantly different. Positive correlations of postprandial plasma glucose (PPG) levels with FSSG scores (R=0.321, p<0.05), particularly with reflux scores (R=0.455, p<0.01) were revealed. PPG and HbA1c levels were not correlated with SDS scores. The patients’ SDS scores were significantly correlated with their FSSG scores (R=0.41, p<0.01), suggesting that depressive status is linked to GERD-related manifestations. Considering that the patients’ PPG levels were correlated with GERD-related symptoms, diabetic patients’ blood glucose levels are associated with depressive status. Collectively, key symptoms related to GERD and glucose level values would be helpful en-copyright= kn-copyright= en-aut-name=HondaHiroyuki en-aut-sei=Honda en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HanayamaYoshihisa en-aut-sei=Hanayama en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ObikaMikako en-aut-sei=Obika en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HasegawaKou en-aut-sei=Hasegawa en-aut-mei=Kou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HamaharaJun en-aut-sei=Hamahara en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KishidaMasayuki en-aut-sei=Kishida en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OgawaHiroko en-aut-sei=Ogawa en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KataokaHitomi en-aut-sei=Kataoka en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=blood glucose kn-keyword=blood glucose en-keyword= type 2 diabetes mellitus kn-keyword= type 2 diabetes mellitus en-keyword=gastroesophageal reflux kn-keyword=gastroesophageal reflux en-keyword=depressive status kn-keyword=depressive status en-keyword=postprandial plasma glucose kn-keyword=postprandial plasma glucose END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=3 article-no= start-page=2963 end-page=2969 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190725 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of a novel method for visualizing restricted diffusion using subtraction of apparent diffusion coefficient values en-subtitle= kn-subtitle= en-abstract= kn-abstract= In order to visualize restricted diffusion, the present study developed a novel method called 'apparent diffusion coefficient (ADC) subtraction method (ASM)' and compared it with diffusion kurtosis imaging (DKI). The diffusion-weighted images of physiological saline, in addtion to bio-phatoms of low cell density and the highest cell density were obtained using two sequences with different effective diffusion times. Then, the calculated ADC values were subtracted. The mean values and standard deviations (SD) of the ADC values of physiological saline, low cell density and the highest cell density phantoms were 2.95 +/- 0.08x10(-3), 1.90 +/- 0.35x10(-3) and 0.79 +/- 0.05x10(-3) mm(2)/sec, respectively. The mean kurtosis values and SD of DKI were 0.04 +/- 0.01, 0.44 +/- 0.13 and 1.27 +/- 0.03, respectively. The ASM and SD values were 0.25 +/- 0.20x10(4), 0.51 +/- 0.41x10(4) and 4.80 +/- 4.51x10(4) (sec/mm(2))(2), respectively. Using bio-phantoms, the present study demonstrated that DKI exhibits restricted diffusion in the extracellular space. Similarly, ASM may reflect the extent of restricted diffusion in the extracellular space. en-copyright= kn-copyright= en-aut-name=YoshimuraYuuki en-aut-sei=Yoshimura en-aut-mei=Yuuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KurodaMasahiro en-aut-sei=Kuroda en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugiantoIrfan en-aut-sei=Sugianto en-aut-mei=Irfan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KhasawnehAbdullah en-aut-sei=Khasawneh en-aut-mei=Abdullah kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BamgboseBabatunde O. en-aut-sei=Bamgbose en-aut-mei=Babatunde O. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HamadaKentaro en-aut-sei=Hamada en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=BarhamMajd en-aut-sei=Barham en-aut-mei=Majd kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TekikiNouha en-aut-sei=Tekiki en-aut-mei=Nouha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KurozumiAkira en-aut-sei=Kurozumi en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsushitaToshi en-aut-sei=Matsushita en-aut-mei=Toshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OhnoSeiichiro en-aut-sei=Ohno en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KanazawaSusumu en-aut-sei=Kanazawa en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=AsaumiJunichi en-aut-sei=Asaumi en-aut-mei=Junichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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 Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Central Division of Radiology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Central Division of Radiology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Central Division of Radiology, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=magnetic resonance imaging kn-keyword=magnetic resonance imaging en-keyword=apparent diffusion coefficient kn-keyword=apparent diffusion coefficient en-keyword=diffusion kurtosis imaging kn-keyword=diffusion kurtosis imaging en-keyword=subtraction kn-keyword=subtraction en-keyword=restricted diffusion kn-keyword=restricted diffusion en-keyword=bio-phantom kn-keyword=bio-phantom en-keyword=cell kn-keyword=cell END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue= article-no= start-page=4722 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=2019318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Specific modification at the C-terminal lysine residue of the green fluorescent protein variant, GFPuv, expressed in Escherichia coli en-subtitle= kn-subtitle= en-abstract= kn-abstract=Green fluorescent protein (GFP) is amenable to recombinant expression in various kinds of cells and is widely used in life science research. We found that the recombinant expression of GFPuv, a commonly-used mutant of GFP, in E. coli produced two distinct molecular species as judged by in-gel fluorescence SDS-PAGE. These molecular species, namely form I and II, could be separately purified by anion-exchange chromatography without any remarkable differences in the fluorescence spectra. Mass spectrometric analyses revealed that the molecular mass of form I is almost the same as the calculated value, while that of form II is approximately 1 Da larger than that of form I. Further mass spectrometric top-down sequencing pinpointed the modification in GFPuv form II, where the epsilon-amino group of the C-terminal Lys238 residue is converted into the hydroxyl group. No equivalent modification was observed in the native GFP in jellyfish Aequorea victoria, suggesting that this modification is not physiologically relevant. Crystal structure analysis of the two species verified the structural identity of the backbone and the vicinity of the chromophore. The modification found in this study may also be generated in other GFP variants as well as in other recombinant expression systems. en-copyright= kn-copyright= en-aut-name=NakataniTakahiro en-aut-sei=Nakatani en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YasuiNorihisa en-aut-sei=Yasui en-aut-mei=Norihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TamuraIssei en-aut-sei=Tamura en-aut-mei=Issei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamashitaAtsuko en-aut-sei=Yamashita en-aut-mei=Atsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil= Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil= Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil= Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=6 article-no= start-page=523 end-page=528 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201912 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bilateral Anterior Cruciate Ligament Tear Combined with Medial Meniscus Posterior Root Tear en-subtitle= kn-subtitle= en-abstract= kn-abstract= The case of an individual with a bilateral anterior cruciate ligament (ACL) tear combined with a medial meniscus (MM) posterior root tear is described. A 34-year-old Japanese man with bilateral ACL rupture that occurred > 10 years earlier was diagnosed with bilateral ACL tear combined with MM posterior root tear (MMPRT). We performed a transtibial pullout repair of the MMPRT with ACL reconstruction. The tibial tunnels for the MM posterior root repair and ACL reconstruction were created separately. Postoperatively, a good clinical outcome and meniscal healing were obtained. Our surgical technique may thus contribute to anatomical MM posterior root repair and ACL reconstruction. en-copyright= kn-copyright= en-aut-name=HiranakaTakaaki en-aut-sei=Hiranaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkazakiYoshiki en-aut-sei=Okazaki en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KamatsukiYusuke en-aut-sei=Kamatsuki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasudaShin en-aut-sei=Masuda en-aut-mei=Shin 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=TakihiraShota en-aut-sei=Takihira en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyazawaShinichi en-aut-sei=Miyazawa en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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 Intelligent Orthopaedic System Development, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Musculoskeletal Traumatology, 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=bilateral anterior cruciate ligament tear kn-keyword=bilateral anterior cruciate ligament tear en-keyword=medial meniscus posterior root tear kn-keyword=medial meniscus posterior root tear en-keyword=pullout repair kn-keyword=pullout repair en-keyword=case report kn-keyword=case report END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=6 article-no= start-page=517 end-page=522 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201912 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Two-year Results of Intravitreal Ranibizumab Injections Using a Treat-and-extend Regimen for Macular Edema due to Branch Retinal Vein Occlusion en-subtitle= kn-subtitle= en-abstract= kn-abstract= We investigated the effectiveness of a treat-and-extend regimen (TAE) of intravitreal ranibizumab injections for macular edema (ME) due to branch retinal vein occlusion (BRVO). We retrospectively examined 2-year results of 32 eyes of 32 patients who underwent TAE to treat ME due to BRVO. The patients whose treatment interval extended to ? 12 weeks were switched to a pro re nata regimen (PRN). For the patients whose treatment interval was <12 weeks, TAE was continued. At 2 years, 10 eyes had required no additional injections after the initial treatment period [recurrence(?) group], whereas the other 22 eyes required additional treatment [recurrence(+) group]. Among the recurrence(+) patients, 11 eyes (34.4% of total) were eventually switched from TAE to PRN; the other 11 eyes (34.4%) continued TAE for 2 years. Visual acuity and central retinal thickness were significantly improved in both the recurrence(+) and (?) groups, and there was no significant betweengroup difference in visual acuity at 2 years. Univariate analyses revealed significant differences in visual acuity (p=0.004), age (p=0.014), and vessel occlusion site (p=0.018) between these groups. Our results suggest that TAE may be effective for BRVO patients with lower visual acuity, older age, and occlusion of a major vein. en-copyright= kn-copyright= en-aut-name=HosogiMika en-aut-sei=Hosogi en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShiodeYusuke en-aut-sei=Shiode en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorizaneYuki en-aut-sei=Morizane en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KimuraShuhei en-aut-sei=Kimura en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HosokawaMio en-aut-sei=Hosokawa en-aut-mei=Mio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DoiShinichiro en-aut-sei=Doi en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ToshimaShinji en-aut-sei=Toshima en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakahashiKosuke en-aut-sei=Takahashi en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiwaraAtsushi en-aut-sei=Fujiwara en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ShiragaFumio en-aut-sei=Shiraga en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences en-keyword=branch retinal vein occlusion kn-keyword=branch retinal vein occlusion en-keyword=macular edema kn-keyword=macular edema en-keyword=anti-vascular endothelial growth factor kn-keyword=anti-vascular endothelial growth factor en-keyword=ranibizumab kn-keyword=ranibizumab en-keyword=treat-and-extend regimen kn-keyword=treat-and-extend regimen END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=6 article-no= start-page=503 end-page=510 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201912 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Early Arthroscopic Pullout Repair of Medial Meniscus Posterior Root Tear Is More Effective for Reducing Medial Meniscus Extrusion en-subtitle= kn-subtitle= en-abstract= kn-abstract= Clinical studies have demonstrated that transtibial pullout repair led to favorable midterm outcomes in patients with medial meniscus posterior root tears (MMPRTs) although medial meniscal extrusion (MME) continued to be present. It has been unclear whether these residual postoperative MMEs existed after the pullout repair or had progressed at the very short-term evaluation after surgery. We sought to determine which characteristics of patients with MMPRTs influence the incidence of postoperative MME. The cases of 23 patients whose date of injury was known were analyzed. All patients underwent MMPRT pullout fixation. Preoperative and 3-month postoperative magnetic resonance imaging (MRI) examinations were performed. MME was retrospectively assessed on the mid-coronal plane of MRI scans. The preoperative and postoperative MME values were 4.2±1.2 mm and 4.3±1.5 mm, respectively (p=0.559). Pullout repair surgery was performed significantly earlier after the MMPRT-specific injury in patients whose postoperative MME improved compared to the patients whose MME did not improve (p<0.001). Our findings demonstrated that an early transtibial pullout repair of an MMPRT was more effective in reducing MME than a late repair. Surgeons should not miss the optimal timing for the pullout repair of an MMPRT, considering the period from the injury and the preoperative MME. en-copyright= kn-copyright= en-aut-name=KamatsukiYusuke en-aut-sei=Kamatsuki en-aut-mei=Yusuke 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=MiyazawaShinichi en-aut-sei=Miyazawa en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KodamaYuya en-aut-sei=Kodama en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HinoTomohito en-aut-sei=Hino en-aut-mei=Tomohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkazakiYoshiki en-aut-sei=Okazaki en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MasudaShin en-aut-sei=Masuda en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=NodaTomoyuki en-aut-sei=Noda en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YamakawaYasuaki en-aut-sei=Yamakawa en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TetsunagaTomoko en-aut-sei=Tetsunaga en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= 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 Intelligent Orthopaedic System, 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 Musculoskeletal traumatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Emergency Healthcare and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=medial meniscus kn-keyword=medial meniscus en-keyword=posterior root tear kn-keyword=posterior root tear en-keyword=pullout repair kn-keyword=pullout repair en-keyword=medial meniscus extrusion kn-keyword=medial meniscus extrusion en-keyword=magnetic resonance imaging kn-keyword=magnetic resonance imaging END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=6 article-no= start-page=487 end-page=494 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201912 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Foveal Structural Analysis of Amblyopic Eyes with Two Types of Fixation Behavior by Spectral-Domain Optical Coherence Tomography en-subtitle= kn-subtitle= en-abstract= kn-abstract= We used spectral-domain optical coherence tomography (SD-OCT) to compare the foveal and parafoveal structures of 19 subjects aged 16-58 years (8 men, 11 women): 6 amblyopic patients with eccentric fixation, 5 amblyopic patients with central fixation, and 8 visually normal controls. We obtained foveal horizontal line scans using SD-OCT on all of the patients and controls. The total and layer thicknesses at foveal areas were analyzed. The mean (SD) ages of individuals in the eccentric fixation, central fixation, and control groups were 43.0 (13.9), 42.2 (16.3), and 38.5 (15.5) years, respectively. We observed no significant differences in the foveal or parafoveal retinal thicknesses at 500 and 1,500 μm from the foveal center among the 3 groups or between the amblyopic and fellow eyes. No significant differences were observed in the thickness of the ganglion cell complex layer or outer retinal layer at 500 and 1,500 μm from the foveal center among the three groups or between the two eyes. Overall, our SD-OCT analyses revealed no characteristic structural change in foveal regions in amblyopic eyes irrespective of the fixation behavior. en-copyright= kn-copyright= en-aut-name=KishimotoFumiko en-aut-sei=Kishimoto en-aut-mei=Fumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiiChiaki en-aut-sei=Fujii en-aut-mei=Chiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkanouchiToshio en-aut-sei=Okanouchi en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OhtsukiHiroshi en-aut-sei=Ohtsuki en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Phamaceutical Sciences kn-affil= affil-num=2 en-affil=Division of Ophthalmology, Ibara Municipal Hospital kn-affil= affil-num=3 en-affil=Division of Ophthalmology, Kurashiki Medical Center kn-affil= affil-num=4 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Phamaceutical Sciences kn-affil= en-keyword=foveal structure kn-keyword=foveal structure en-keyword=strabismic amblyopia kn-keyword=strabismic amblyopia en-keyword=optical coherence tomography kn-keyword=optical coherence tomography en-keyword=eccentric fixation kn-keyword=eccentric fixation END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=6 article-no= start-page=479 end-page=486 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201912 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Correlations between Depressive Condition and Gastroesophageal Reflux Symptoms in Patients Visiting a Department of General Medicine en-subtitle= kn-subtitle= en-abstract= kn-abstract= To clarify the potential relevance of patients’ chief complaints at a general medicine department to their self-rating depression scale (SDS) and frequency scale for symptoms of gastroesophageal reflux disease (GERD) (FSSG) scores, we analyzed data of 478 patients who visited our general medicine department. The chief complaints (553 symptoms of 447 patients) were categorized into major symptom-based groups: respiratory (31%), circulatory (3%), gastrointestinal (GI) tract (26%), neurology (8%), orthopedic and skin (10%), and systemic (22%) symptoms. The SDS score tended to be higher in females and younger patients. The FSSG score did not differ by gender but was higher in younger patients. The patients receiving social welfare had higher SDS and FSSG scores. A close inter-relationship between the FSSG (including both degrees of reflux and dysmotility) and SDS was observed in all patients. Although the averages of the SDS and FSSG scores were not significantly different among the symptom-based categories, we observed significantly positive correlations between the FSSG and SDS in each category, suggesting that depressive status may be closely related to GERD-related symptoms regardless of the patients’ chief complaints. An initial checkup of patients’ psychological condition and/or GERD-like symptoms could help screen for latent disorders in outpatients with uncertain complaints. en-copyright= kn-copyright= en-aut-name=SuganamiYu en-aut-sei=Suganami en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkaKosuke en-aut-sei=Oka en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HanayamaYoshihisa en-aut-sei=Hanayama en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HondaHiroyuki en-aut-sei=Honda en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HamaharaJun en-aut-sei=Hamahara en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ObikaMikako en-aut-sei=Obika en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KariyamaKazuya en-aut-sei=Kariyama en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KishidaMasayuki en-aut-sei=Kishida en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= 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= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=chief complaints kn-keyword=chief complaints en-keyword=frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) kn-keyword=frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) en-keyword=self-rating depression scale (SDS) kn-keyword=self-rating depression scale (SDS) en-keyword=welfare kn-keyword=welfare END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=4 article-no= start-page=349 end-page=356 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201908 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Significance of Microcalcifications on Mammography in the Surgical Treatment of Breast Cancer Patients with a Preoperative Diagnosis of Ductal Carcinoma in Situ by Core Needle Biopsy en-subtitle= kn-subtitle= en-abstract= kn-abstract= To clarify the surgical outcomes of breast cancer patients with a preoperative diagnosis of ductal carcinoma in situ (DCIS) by core needle biopsy (CNB) (abbreviated as CNBDCIS), we retrospectively analyzed the cases of 131 patients with CNBDCIS who underwent surgery at Oomoto Hospital (32 total mastectomies, 99 conservative mastectomies). Our analysis of underestimation and predictors of invasive breast cancer of CNBDCIS revealed that the underestimation rate of CNBDCIS was 40.5% (53/131). A logistic regression analysis revealed that palpable tumors (yes to no, odds ratio [OR] 3.25), mammography (MMG) category group (category 4 or 5 to categories 1 , 2, or 3, OR 4.69) and MMG microcalcifications (no to yes, OR 0.24) were significant predictive factors for CNBDCIS invasion. In our analysis of the predictors of positive margins during CNBDCIS surgery, 36 (27.5%) of the 131 patients had positive margins after postoperative pathological examination. A logistic regression analysis revealed that the operative procedure (conservative surgery to total mastectomy, OR 21.4) and MMG microcalcifications (yes to no, OR 3.35) were significant factors related to positive margins during CNBDCIS surgery. Thus, MMG microcalcifications are a negative predictor of upgrading of CNBDCIS and a positive predictor of positive surgical margins for CNBDCIS. en-copyright= kn-copyright= en-aut-name=IsozakiHiroshi en-aut-sei=Isozaki en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoYasuhisa en-aut-sei=Yamamoto en-aut-mei=Yasuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MurakamiShigeki en-aut-sei=Murakami en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumotoSasau en-aut-sei=Matsumoto en-aut-mei=Sasau kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakamaTakehiro en-aut-sei=Takama en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Surgery, Oomoto Hospital kn-affil= affil-num=2 en-affil=Department of Surgery, Oomoto Hospital kn-affil= affil-num=3 en-affil=Department of Surgery, Oomoto Hospital kn-affil= affil-num=4 en-affil=Department of Surgery, Oomoto Hospital kn-affil= affil-num=5 en-affil=Department of Surgery, Oomoto Hospital kn-affil= en-keyword=ductal carcinoma in situ kn-keyword=ductal carcinoma in situ en-keyword=core needle biopsy kn-keyword=core needle biopsy en-keyword=underestimation kn-keyword=underestimation en-keyword=positive margins kn-keyword=positive margins en-keyword=microcalcifications on mammography kn-keyword=microcalcifications on mammography END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=4 article-no= start-page=285 end-page=297 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201908 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dynamic Reorganization of Microtubule and Glioma Invasion en-subtitle= kn-subtitle= en-abstract= kn-abstract= Gliomas are characterized as highly diffuse infiltrating tumors, and currently available treatments such as surgery, radiation and chemotherapy are unfeasible or show limited efficacy against these tumors.

Despite these findings, the survival rates of glioma patients remain low, and alternative treatments and novel targets are needed. Recent studies identified neural stem cells as the possible origin of gliomas, and some evidence has revealed shared functions and mechanisms between glioma cells and neurons, also supporting their similarity. The cytoskeleton plays important roles in the migration of normal cells as well as cancer cells. Recent reports have described a role for microtubules, a component of the cytoskeleton, in glioma invasion. Notably, several factors that regulate microtubule functions, such as microtubule-associated proteins, plus-end tracking proteins, or motor proteins, are upregulated in glioma tissues compared with normal tissue, and upregulation of these factors is associated with high invasiveness of glioma cells. In this review, we describe the mechanism of microtubules in glioma invasion and discuss the possibility of microtubule-targeted therapy to inhibit glioma invasion. en-copyright= kn-copyright= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchikawaTomotsugu en-aut-sei=Ichikawa en-aut-mei=Tomotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Neurosurgery, The University of Texas Health Science Center at Houston kn-affil= affil-num=2 en-affil=Department of Neurosurgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=glioma kn-keyword=glioma en-keyword=cytoskeletons kn-keyword=cytoskeletons en-keyword=invasion kn-keyword=invasion en-keyword=microtubules kn-keyword=microtubules END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=3 article-no= start-page=205 end-page=211 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201906 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Laparoscopic Rectosigmoid Colon Vaginoplasty in Male-to-Female Transsexuals: Experience in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract= Intestinal vaginoplasty has several advantageous features, such as scarless surgery, low incidence of contraction of the reconstructed vagina, maintenance of vaginal depth, spontaneous mucus production, and a low rate of complications. Therefore, this technique is becoming popular in many countries. Following the global trend, the demand for intestinal vaginoplasty for transsexuals is also increasing in Japan. However, there are few reports on intestinal vaginoplasty in Japan. In this study, we examined the safety and effectiveness of rectosigmoid colon vaginoplasty in the Japanese population. We retrospectively surveyed 18 male-to-female transsexuals who underwent laparoscopic rectosigmoid colon vaginoplasty at the Okayama University Hospital Gender Center between October 2012 and December 2017. One patient had developed an anastomotic leak and 2 patients experienced vaginal prolapse, which needed revision surgery. Both adverse outcomes were comparable with those from previous studies. The anastomotic leak was managed adequately with conservative treatment. To avoid vaginal prolapse, it is important to decide the length of the rectosigmoid segment so that a pull on it does not cause it to become lax, while excessive stress on the feeder vessels is avoided. Based on our study, we concluded that rectosigmoid vaginoplasty was a reliable technique in the Japanese population. en-copyright= kn-copyright= en-aut-name=MukaiYuko en-aut-sei=Mukai en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakuraiToru en-aut-sei=Sakurai en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeToshiyuki en-aut-sei=Watanabe en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakoTomoko en-aut-sei=Sako en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugimotoMorito en-aut-sei=Sugimoto en-aut-mei=Morito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=MoriYoshiko en-aut-sei=Mori en-aut-mei=Yoshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NagasakaTakeshi en-aut-sei=Nagasaka en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NambaYuzaburo en-aut-sei=Namba en-aut-mei=Yuzaburo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Urology, Onomichi Municipal Hospital kn-affil= affil-num=6 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Clinical Oncology, Kawasaki Medical School Hospital kn-affil= affil-num=9 en-affil=Department of Gender Center, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=vaginoplasty kn-keyword=vaginoplasty en-keyword=male-to-female transsexuals kn-keyword=male-to-female transsexuals en-keyword=rectosigmoid colon kn-keyword=rectosigmoid colon END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=3 article-no= start-page=197 end-page=203 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201906 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Geriatric Trauma in Patients ≧85 Years Old in an Urban District of Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract= Japan's population has been skewing toward the elderly, but the outcomes of advanced elderly trauma are not clear. Here we compared the outcomes of very elderly trauma patients (≧85 years old) with those of 65- to 84-year-old trauma patients. We retrospectively reviewed the medical records of patients treated at Hyogo Emergency Medical Center from August 2010 to August 2016; 631 patients were entered in the study. We divided them into the younger geriatrics (YG group, 65-84 years old: n=534) and older geriatrics (OG group, ≧85 years old: n=97). The group’s patient characteristics, mortality, 1-year survival rate, and Barthel index were tabulated and compared. The patients’ mean age was 75.6±7.5 years. There was no significant difference in mortality between the YG and OG groups (9.6% vs. 15.1%, odds ratio [OR] 1.73; 95% confidence interval [CI] 0.93-3.23, p=0.083). The 1-year survival rate (94.4% vs. 77.8%, OR 0.19, 95% CI 0.07-0.51; p<0.01) and Barthel index (Median score; 100 (IQR: 85-100) vs. 80 (IQR: 15-95), OR 0.98, 95% CI 0.97 to 0.99, p<0.01) differed significantly between the groups. Our study did not find a significant difference in-hospital mortality between patients in the YG group and those in the OG group. en-copyright= kn-copyright= en-aut-name=NishimuraTakeshi en-aut-sei=Nishimura en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuyamaShigenari en-aut-sei=Matsuyama en-aut-mei=Shigenari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshiharaSatoshi en-aut-sei=Ishihara en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakayamaShinichi en-aut-sei=Nakayama en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Emergency and Critical Care Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Emergency and Critical Care Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Hyogo Emergency Medical Center kn-affil= affil-num=4 en-affil=Hyogo Emergency Medical Center kn-affil= affil-num=5 en-affil=Department of Emergency and Critical Care Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Hyogo Emergency Medical Center kn-affil= en-keyword=aged kn-keyword=aged en-keyword=injury kn-keyword=injury en-keyword=mortality kn-keyword=mortality en-keyword=morbidity kn-keyword=morbidity en-keyword=trauma kn-keyword=trauma END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=1 article-no= start-page=77 end-page=80 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201902 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Flap Reconstruction for Esophageal Perforation Following Anterior Cervical Plate Fixation en-subtitle= kn-subtitle= en-abstract= kn-abstract= Anterior cervical plate fixation is a common surgical treatment for cervical spine trauma, disc herniation, or cervical spondylosis. Esophageal perforation following anterior cervical plate fixation is a rare but serious complication. Management of esophageal perforation is controversial; however, we suggest treating most cases surgically because this condition is slow to heal and often fatal. We managed 2 cases of esophageal perforation following anterior cervical plate fixation by flap reconstruction with the pectoralis major muscle in one case and a jejunal free flap in the other. Here, we report our experience and review the surgical indications. en-copyright= kn-copyright= en-aut-name=MoritaMio en-aut-sei=Morita en-aut-mei=Mio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoHiroshi en-aut-sei=Matsumoto en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShirakawaYasuhiro en-aut-sei=Shirakawa en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanabeShunsuke en-aut-sei=Tanabe en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= affil-num=1 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=2 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=6 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= en-keyword=anterior cervical plate fixation kn-keyword=anterior cervical plate fixation en-keyword=esophageal perforation kn-keyword=esophageal perforation en-keyword=reconstruction kn-keyword=reconstruction en-keyword=pectoralis major flap kn-keyword=pectoralis major flap en-keyword=jejunal free flap kn-keyword=jejunal free flap END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=1 article-no= start-page=41 end-page=50 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201902 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Predictive Factors for Successful Vaccination Against Hepatitis B Surface Antigen in Patients Who Have Undergone Orthotopic Liver Transplantation en-subtitle= kn-subtitle= en-abstract= kn-abstract= Post-orthotopic liver transplantation (OLT) hepatitis B recurrence is well-controlled with a nucleos(t)ide analogue and hepatitis B immunoglobulin (HBIG) combination, but the high cost and the potential risk of unknown infection associated with HBIG remain unresolved issues. Low-cost recombinant hepatitis B virus (HBV) vaccine administration is a potential solution to these problems. We retrospectively analyzed the rate and predictive factors of HBV vaccine success in 49 post-OLT patients: liver cirrhosis-type B (LC-B), n=28 patients; acute liver failure-type B (ALF-B), n=8; and non-HBV-related end-stage liver disease (non-B ESLD) who received a liver from anti-hepatitis B core antibody-positive donors, n=13. A positive anti-hepatitis B surface antibody response was achieved in 29% (8/28) of the LC-B group, 88% (7/8) of the ALF-B group, and 44% (4/9) of the adult non-B ESLD group. All four non-B ESLD infants showed vaccine success. The predictive factors for a good response in LC-B were young age, marital donor, and high donor age. ALF-B and non-B ESLD infants are thus good vaccination candidates. LC-B patients with marital donors are also good candidates, perhaps because the donated liver maintains an efficient immune memory to HBV, as the donors had already been infected in adulthood and showed adequate anti-HBV immune responses. en-copyright= kn-copyright= en-aut-name=IkedaAilee en-aut-sei=Ikeda en-aut-mei=Ailee kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

The phrenic nerve was stimulated at the posterior border of the sternomastoid muscle in the supraclavicular fossa, just above the clavicle, with bipolar surface electrodes. For recording, positive and negative electrodes were placed on the xiphoid process and at the eighth intercostal bone-cartilage transition, respectively. We studied both the right and left sides to determine whether there was any difference between the two sides. The mean onset latency (± SD) of the right compound muscle action potentials (CMAPs) (5.99±0.39 msec) was significantly shorter than that of the left CMAPs (6.45±0.50 msec). The mean peak latency was significantly shorter in the right CMAPs (10.22±1.33 msec) than the left CMAPs (12.48±2.02 msec). The mean (± SD) amplitude was significantly lower in the left CMAPs (0.42±0.11 mV) than the right CMAPs (0.49±0.10 mV). The difference between the length of the nerve on the right and left sides might have affected the difference in latency between the two sides. en-copyright= kn-copyright= en-aut-name=KatayamaYoshimi en-aut-sei=Katayama en-aut-mei=Yoshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SendaMasuo en-aut-sei=Senda en-aut-mei=Masuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanedaDaisuke en-aut-sei=Kaneda en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=phrenic nerve kn-keyword=phrenic nerve en-keyword=right left difference kn-keyword=right left difference en-keyword=healthy subject kn-keyword=healthy subject en-keyword=nerve conduction kn-keyword=nerve conduction END start-ver=1.4 cd-journal=joma no-vol=34 cd-vols= no-issue= article-no= start-page=10 end-page=16 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=201804 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=What enables hibernation? : insights from a mammalian hibernator, Syrian hamster kn-title=冬眠する哺乳類シリアンハムスターに学ぶ、冬眠可能な生体状態とは？ en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hibernation is an adaptive strategy for surviving during periods with little or no food availability, by profoundly reducing the metabolic rate and the core body temperature (Tb). Mammalian hibernators store fat extensively in white adipose tissues (WATs) during pre-hibernation period to prepare for hibernation. Thus, they undergo adaptive body remodelling in autumn, the pre-hibernation period, prior to hibernation, whereas little is known about the physiological and molecular mechanisms of the pre-hibernation remodelling. Syrian hamsters (Mesocricetus auratus) are facultative hibernators that can hibernate irrespective of seasons when exposed to prolonged short photoperiod and cold ambient temperature (SD-Cold) conditions. We found that before the initiation of hibernation, the body mass of Syrian hamsters decreased below a threshold, indicating that hibernation in this species depends on body condition. Global profiling of gene expression in various tissues of animals during the pre-hibernation period and hibernation period identified adaptive changes for hibernation at molecular level. Thus, Syrian hamsters as a model animal to study hibernation provide us a unique and convenient opportunity to analyse molecular and physiological mechanisms of adaptive pre-hibernation remodelling under a laboratory condition. en-copyright= kn-copyright= en-aut-name=YamaguchiYoshifumi en-aut-sei=Yamaguchi en-aut-mei=Yoshifumi kn-aut-name=山口良文 kn-aut-sei=山口 kn-aut-mei=良文 aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Genetics, Graduate School of Pharmaceutical Science, University of Tokyo kn-affil=東京大学 大学院薬学系研究科 END start-ver=1.4 cd-journal=joma no-vol=72 cd-vols= no-issue=2 article-no= start-page=115 end-page=119 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=201804 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Formulae Based on Biomathematics to Estimate the Standard Value of Fetal Growth of Japanese en-subtitle= kn-subtitle= en-abstract= kn-abstract= We devised biomathematics-based formulae to estimate the standard values of fetal growth of Japanese after 22 weeks' gestation. The growth rates of bi-parietal diameter (BPD), abdominal circumference (AC), femur length (FL), and estimated fetal body weight (EFBW) at the time of gestation were assumed to be proportional to the product of the value at the time and the rest value of an unknown maximum value, respectively. The EFBW was also assumed to follow a multiple logistic function of BPD, AC and FL to fit the standard values of Japanese fetuses published by the Japan Society of Ultrasonics in Medicine. The Mann-Whitney test was used for statistical analysis. The values as a function of gestational day, t, were as follows: BPD(t)=99.6/(1+exp (2.725?0.01837＊t)) (mm); AC(t)=39.7/(1+exp (2.454?0.01379＊t)) (cm); FL(t)=79.6/(1+exp (2.851?0.01710＊t)) (mm); EFBW(t)=8045.1/(1+exp (6.028?0.06582＊BPD(t)?0.1469＊AC(t)+ 0.07377＊FL(t))) (g). EFBW as a function of BPD, AC and FL was as follows: EFBW=8045.1/(1+exp (4.747+ 0.02584＊BPD+0.1010＊AC?0.1416＊FL)) (g). When the BPD, AC and FL were at ?2 standard deviation (SD), ?1SD, mean and + 2SD, the EFBW values calculated by the formula were statistically closer to the standard values than conventional formulas with p-values of 4.871×10?7, 4.228×10?7, 9.777×10?7 and 0.028, respectively. The formulae based on biomathematics might be useful to estimate the fetal growth standard values. en-copyright= kn-copyright= en-aut-name=MiyagiYasunari en-aut-sei=Miyagi en-aut-mei=Yasunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TadaKatsuhiko en-aut-sei=Tada en-aut-mei=Katsuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakayoshiRiko en-aut-sei=Takayoshi en-aut-mei=Riko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OguniNobutsugu en-aut-sei=Oguni en-aut-mei=Nobutsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SatoYasushi en-aut-sei=Sato en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShibataMaki en-aut-sei=Shibata en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KiyokawaMachiko en-aut-sei=Kiyokawa en-aut-mei=Machiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HashimotoTadashi en-aut-sei=Hashimoto en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakadaTomoyoshi en-aut-sei=Takada en-aut-mei=Tomoyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OdaTakashi en-aut-sei=Oda en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MiyakeTakahito en-aut-sei=Miyake en-aut-mei=Takahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Gynecology, Miyake Ofuku Clinic kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama Medical Cente kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Miyake Clinic kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Miyake Clinic kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Miyake Clinic kn-affil= affil-num=6 en-affil=Department of Obstetrics and Gynecology, Miyake Clinic kn-affil= affil-num=7 en-affil=Department of Obstetrics and Gynecology, Miyake Clinic kn-affil= affil-num=8 en-affil=Department of Obstetrics and Gynecology, Miyake Clinic kn-affil= affil-num=9 en-affil=Department of Obstetrics and Gynecology, Miyake Clinic kn-affil= affil-num=10 en-affil=Department of Obstetrics and Gynecology, Miyake Clinic kn-affil= affil-num=11 en-affil=Department of Obstetrics and Gynecology, Miyake Clinic kn-affil= en-keyword=fetal growth kn-keyword=fetal growth en-keyword= formulae kn-keyword= formulae en-keyword=biomathematics kn-keyword=biomathematics en-keyword=Japanese kn-keyword=Japanese en-keyword=ultrasound kn-keyword=ultrasound END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue= article-no= start-page=207 end-page=212 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20180320 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Review of the U.S. Supreme Court decision in Endrew F. v.

Douglas County School District " (2017) in the U.S. Supreme Court. The Individuals with Disabilities Education Act (IDEA) requires to guarantee a free appropriate public education (FAPE) for students with disabilities. In the "Board of Education of the Hendrick Hudson Central School District v. Rowley " (1982), the U.S. Supreme Court was rejected requirement to maximize educational potential of student. This decision has been quoted for a long time in the lower courts. However, new standard in the Andrew case was judged.

Douglas County SD , 2017）の論点を捉えることにより，今後のインクルーシブ教育のあり方の検討に必要な基礎資料を提供することを目的とした。米国では障害者教育法(IDEA)により，障害のある子どもに対する「無償で適切な公教育」（FAPE）が保障されている。従来，FAPEが求める教育成果の水準に関しては，1980年代の最高裁判所判決（Board of Educ. v. Rowley , 1982）が大きな影響を与えてきた。つまり，FAPEの要求は「最小限を満たすもの」であれば足りると解釈されてきた。しかしながら，Endrew 裁判によって，実質的な意味のある教育成果が求められることが判示された。今後，本裁判を契機に，障害のある子どもに対する教育の成果がこれまで以上に大きな議論となることも予想できる。 en-copyright= kn-copyright= en-aut-name=AmanoYumi en-aut-sei=Amano en-aut-mei=Yumi kn-aut-name=天野佑美 kn-aut-sei=天野 kn-aut-mei=佑美 aut-affil-num=1 ORCID= en-aut-name=LiuWenhao en-aut-sei=Liu en-aut-mei=Wenhao kn-aut-name=劉文浩 kn-aut-sei=劉 kn-aut-mei=文浩 aut-affil-num=2 ORCID= en-aut-name=ZhaoBingyan en-aut-sei=Zhao en-aut-mei=Bingyan kn-aut-name=趙氷雁 kn-aut-sei=趙 kn-aut-mei=氷雁 aut-affil-num=3 ORCID= en-aut-name=YoshitoshiMunehisa en-aut-sei=Yoshitoshi en-aut-mei=Munehisa kn-aut-name=吉利宗久 kn-aut-sei=吉利 kn-aut-mei=宗久 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil= kn-affil=岡山大学大学院教育学研究科 affil-num=3 en-affil= kn-affil=岡山大学大学院教育学研究科 affil-num=4 en-affil= kn-affil=岡山大学大学院教育学研究科 en-keyword=無償で適切な公教育 (free appropriate public education) kn-keyword=無償で適切な公教育 (free appropriate public education) en-keyword=個別教育計画 kn-keyword=個別教育計画 en-keyword=教育権 (educational rights) kn-keyword=教育権 (educational rights) en-keyword=判決 (court decisions) kn-keyword=判決 (court decisions) en-keyword=インクルーシブ教育 (inclusive education) kn-keyword=インクルーシブ教育 (inclusive education) END start-ver=1.4 cd-journal=joma no-vol=129 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=20170403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The 2015 Incentive Award of the Okayama Medical Association in Cardiovascular and Pulmonary Research (2015 Sunada Prize) kn-title=平成27年度岡山医学会賞　胸部・循環研究奨励賞（砂田賞） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=IshigamiShuta en-aut-sei=Ishigami en-aut-mei=Shuta kn-aut-name=石神修大 kn-aut-sei=石神 kn-aut-mei=修大 aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil=岡山大学大学院医歯薬学総合研究科　心臓血管外科学 END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=6 article-no= start-page=435 end-page=439 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=201612 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Urinary Cross-linked N-terminal Telopeptide of Type I Collagen Levels of Infants with Osteogenesis Imperfecta and Healthy Infants en-subtitle= kn-subtitle= en-abstract= kn-abstract=The urinary cross-linked N-terminal telopeptide of type I collagen (uNTx) levels in infantile osteogenesis imperfecta (OI) have not been well studied. Here we investigated the levels of uNTx in infants with OI and healthy infants. We collected spot urine samples from 30 infants with OI (male/female, 14/16; Sillence classification, I/II/III/IV: 15/3/6/6; age, 5.2±4.4 months) and 120 healthy infants (male/female, 75/45; age, 5.1±4.1 months) for the measurement of uNTx levels. The uNTx levels of the OI infants were significantly lower than those of the healthy infants (mean±SD, 1,363.7±530.1 vs. 2,622.2±1,202.6 nmol BCE/mmol Cr; p＜0.001). The uNTx levels of the infants with type I OI were significantly lower than those of the age-matched healthy infants, although an overlap was observed between the 2 groups. Among the 1-month-old infants, the uNTx levels of the infants with types I, III or IV OI were significantly lower than those of the healthy infants, without overlap (1,622.5±235.8 vs. 3,781.0±1,027.1 nmol BCE/mmol Cr; p＜0.001). These results indicate that uNTx levels are significantly lower in infants with OI than in healthy infants, and they suggest that uNTx might be useful as a reference for diagnosing OI. en-copyright= kn-copyright= en-aut-name=YamashitaMiho en-aut-sei=Yamashita en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HasegawaKosei en-aut-sei=Hasegawa en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiguchiYousuke en-aut-sei=Higuchi en-aut-mei=Yousuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyaiTakayuki en-aut-sei=Miyai en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkadaAyumi en-aut-sei=Okada en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaHiroyuki en-aut-sei=Tanaka en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=5 en-affil=Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama Saiseikai General Hospital kn-affil= affil-num=7 en-affil=Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=bone resorption marker kn-keyword=bone resorption marker en-keyword=bone turnover kn-keyword=bone turnover en-keyword=bone mass kn-keyword=bone mass END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue= article-no= start-page=5 end-page=12 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20170201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Ginkgo biloba α-fucosidase with activity towards plant complex type N-glycans containing the Lewis a epitope: Purification and characterization en-subtitle= kn-subtitle= en-abstract=　銀杏種子から高分子量 （SDS-PAGE で120 kDa） を有し，α-フコース含有オリゴ糖に活性を示すα-フコシダーゼ（α-fucosidase Gb）を均一に精製した．ルイス a エピトープ含有 N-グリカンを基質とした場合，α-fucosidase Gb の至適 pH は 5.5 付近であることから，本酵素は液胞のような酸性環境で機能していることが示唆された．N?末端アミノ酸配列が化学修飾のため同定できなかったため，本酵素が GH29 ファミリーに属するかどうかは不明である．α-Fucosidase Gb は，Lacto-N-fucopentaose IIIの α1,3-フコース残基やルイス a エピトープ含有の植物複合型N-グリカンのα1,4-フコース残基を加水分解することから，α-フコース含有オリゴ糖やN 型糖タンパク質の分解プロセスに関与することが示唆された． kn-abstract=　We have identified, and purified to homogeneity, a high molecular weight Ginkgo biloba α-fucosidase (α-fucosidase Gb, 120 kDa estimated by SDS?PAGE) with activity against α-fucosylated oligosaccharides. When a Lewis a epitope-containing N-glycan was used as a substrate, α-fucosidase Gb showed optimum activity at approximately pH 5.5, suggesting that it functions in acidic environments such as the vacuole. It remains uncertain, however, whether this Ginkgo α-fucosidase belongs to the GH29 family, since its N-terminal sequence could not be determined, probably due to a chemical modification. α-Fucosidase Gb showed substantial activity towards the α1,3-fucosyl linkage in Lacto-N-fucopentaose III and an α1,4-fucosyl linkage in the Lewis a epitope found in plant complex type N-glycans, indicating an involvement in the degradation process of α-fucosylated oligosaccharides or N-glycoproteins. en-copyright= kn-copyright= en-aut-name=ItanoSatsuki en-aut-sei=Itano en-aut-mei=Satsuki kn-aut-name=板野紗月 kn-aut-sei=板野 kn-aut-mei=紗月 aut-affil-num=1 ORCID= en-aut-name=MaedaMegumi en-aut-sei=Maeda en-aut-mei=Megumi kn-aut-name=前田恵 kn-aut-sei=前田 kn-aut-mei=恵 aut-affil-num=2 ORCID= en-aut-name=Md.

The method consists of a plug?plug reaction between lignin peroxidase and its substrate, veratryl alcohol, the separation of the product, veratraldehyde, from the other components including the enzyme and the culture medium, and the determination of the enzyme activity from the peak area of veratraldehyde produced by the plug?plug reaction. This method is more sensitive than conventional spectrophotometry since the background originates from the enzyme and the culture medium can be removed via MEKC separation. Veratraldehyde was separated at ?10 kV in a background electrolyte containing 50 mM tartrate buffer (pH 2.5) and 50 mM sodium dodecyl sulfate (SDS) after a plug?plug reaction in the capillary for 5 min. The calibration curve of veratraldehyde was linear up to 4 pmol (500 μM) with a limit to quantification of 0.026 pmol (3.2 μM) (SN = 10). The activity of lignin peroxidase was directly measured from the peak area of veratraldehyde. The activity of lignin peroxidase released from P. chrysosporium into the medium for 7 days was successfully determined to be 3.40 UL?1. en-copyright= kn-copyright= en-aut-name=HaradaAiri en-aut-sei=Harada en-aut-mei=Airi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SasakiKeiko en-aut-sei=Sasaki en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanetaTakashi en-aut-sei=Kaneta en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Department of Earth Resources Engineering, Graduate School of Engineering, Kyushu University affil-num=3 en-affil= kn-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University en-keyword=Lignin Peroxidase kn-keyword=Lignin Peroxidase en-keyword=Phanerochaete chrysosporium kn-keyword=Phanerochaete chrysosporium en-keyword=Micellar electrokinetic chromatography kn-keyword=Micellar electrokinetic chromatography en-keyword=Capillary electrophoresis kn-keyword=Capillary electrophoresis en-keyword=Enzyme assay kn-keyword=Enzyme assay END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=1 article-no= start-page=45 end-page=49 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=201602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Importance of Milk Expression for Preterm Infants en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mothers of preterm infants may find it difficult to express breast milk. There is a low breast milk rate among preterm infants at discharge at our hospital, and here we tested the hypothesis that milk expression factors were the cause of the low rate. The study subjects were born before 33 gestational weeks at our hospital between March 2005 and June 2014. Nutritional evaluation was performed at discharge and noted whether breast milk, infant formula, or a mix of the 2 was being given. We compared the group given breast milk or the mix versus the group given formula. Of the 337 infants, 40 cases were excluded. Data from 297 infants were analyzed. The mean (SD) gestational age and birth weight were 29.5 (2.4) weeks and 1,230 (391) g, respectively. At discharge, 26 (8.8%), 102 (33.3%), and 174 (57.9%) infants were given breast milk, formula, and the mix, respectively. A multivariate logistic regression analysis showed that the first milk expression (h) was the risk factor for the formula group: adjusted odds ratio (95% confidence interval) 1.06 (1.02-1.09) and p=0.002. Delayed first milk expression could affect the low breast milk rate at discharge. Improvement of milk expression should be achieved to promote breastfeeding. en-copyright= kn-copyright= en-aut-name=MaruyamaHidehiko en-aut-sei=Maruyama en-aut-mei=Hidehiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakataYusei en-aut-sei=Nakata en-aut-mei=Yusei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanazawaAkane en-aut-sei=Kanazawa en-aut-mei=Akane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KikkawaKiyoshi en-aut-sei=Kikkawa en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Department of Pediatrics, Kochi Health Sciences Center affil-num=2 en-affil= kn-affil=Department of Pediatrics, Kochi Health Sciences Center affil-num=3 en-affil= kn-affil=Department of Pediatrics, Kochi Health Sciences Center affil-num=4 en-affil= kn-affil=Department of Pediatrics, Kochi Health Sciences Center en-keyword=breast milk kn-keyword=breast milk en-keyword=breastfeeding kn-keyword=breastfeeding en-keyword=formula kn-keyword=formula en-keyword=milk expression kn-keyword=milk expression en-keyword=preterm kn-keyword=preterm END start-ver=1.4 cd-journal=joma no-vol=127 cd-vols= no-issue=3 article-no= start-page=219 end-page=222 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=20151201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Drug-induced liver injury due to the long-term oral administration of rosuvastatin kn-title=長期のロスバスタチンカルシウム服用にて発症したと考えられる薬物性肝障害の一例 en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 67-year-old man was admitted to our hospital presenting with a liver injury. He had used several types of oral medication for the prior 2 years, including rosuvastatin calcium for hypertension, hyperlipidemia, and prostatic hypertrophy. His liver dysfunction was noted for the first time in February 2013, and at re-examination in March 2013 he showed exacerbation of the liver dysfunction, he was admitted to our hospital at that time. We stopped all of his oral medications, and his liver function improved steadily. We conducted a drug-induced lymphocyte transformation test (DLST), and the rosuvastatin calcium result was positive. He was diagnosed as having a drug-induced (by rosvastatin calcium) liver injury.

The endocrinology laboratory data showed elevations in the levels of serum noradrenaline, and ectopic pheochromocytoma was suspected. The tumor was compressing the inferior vena cava and portal vein, the superior mesenteric artery and the pancreas. Since it would be difficult to cure by operation, neoadjuvant therapy was started using radioisotope therapy by I-131 metaiodobenzylguanidine (131I-MIBG) and chemotherapy (CVD therapy ; cyclophosphamide, vincristine, dacarbazine). He was treated with three courses of radioisotope therapy and 16 courses of chemotherapy, which significantly reduced the tumor size. This made radical resection possible ; we were able to avoid the merger excision of great vessels and other organs. On pathological and immunopathological findings, the tumor was diagnosed as ectopic　pheochromocytoma. Regarding the safety and curability of the treatment, neoadjuvant therapy may be useful in treating very large tumors that show invasion of other organs. en-copyright= kn-copyright= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name=安井和也 kn-aut-sei=安井 kn-aut-mei=和也 aut-affil-num=1 ORCID= en-aut-name=UmedaYuzo en-aut-sei=Umeda en-aut-mei=Yuzo kn-aut-name=楳田祐三 kn-aut-sei=楳田 kn-aut-mei=祐三 aut-affil-num=2 ORCID= en-aut-name=KumanoKenjiro en-aut-sei=Kumano en-aut-mei=Kenjiro kn-aut-name=熊野健二郎 kn-aut-sei=熊野 kn-aut-mei=健二郎 aut-affil-num=3 ORCID= en-aut-name=TabataMasahiro en-aut-sei=Tabata en-aut-mei=Masahiro kn-aut-name=田端雅弘 kn-aut-sei=田端 kn-aut-mei=雅弘 aut-affil-num=4 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name=大塚文男 kn-aut-sei=大塚 kn-aut-mei=文男 aut-affil-num=5 ORCID= en-aut-name=YagiTakahito en-aut-sei=Yagi en-aut-mei=Takahito kn-aut-name=八木孝仁 kn-aut-sei=八木 kn-aut-mei=孝仁 aut-affil-num=6 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name=藤原俊義 kn-aut-sei=藤原 kn-aut-mei=俊義 aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 affil-num=2 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 affil-num=3 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 affil-num=4 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 affil-num=5 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 affil-num=6 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 affil-num=7 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 en-keyword=異所性褐色細胞腫（ectopic pheochromocytoma） kn-keyword=異所性褐色細胞腫（ectopic pheochromocytoma） en-keyword=化学療法（chemo therapy） kn-keyword=化学療法（chemo therapy） en-keyword=131I-MIBG kn-keyword=131I-MIBG END start-ver=1.4 cd-journal=joma no-vol=69 cd-vols= no-issue=1 article-no= start-page=45 end-page=50 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=201502 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparison of Urinary Levels of 8-Hydroxy-2’-deoxyguanosine between Young Females with and without Depressive Symptoms during Different Menstrual Phases en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to clarify the association between depressive symptoms and a marker of oxidative stress-induced DNA damage in young females. Since the menstrual cycle may confound or modify this association, depressive symptoms and urinary levels of 8-hydroxy-2? deoxyguanosine (8-OHdG) were evaluated during each menstrual phase. A total of 57 female fourth-year students (aged 21.6±0.8) from a Japanese health science university were studied. The menstrual cycle was divided into 3 phases:menstrual (days 1 to 3 after the onset of menses);proliferative (days 13 to 15);and secretory (days 24 to 26). Depressive symptoms were assessed by the self-rating depression scale (SDS). Positive depressive symptoms were defined as a score of 53 or more during 2 different menstrual phases. The association between the presence of depressive symptoms and 8-OHdG levels adjusting for the menstrual cycle was examined by two-way analysis of variance with the menstrual cycle (menstrual, proliferative, and secretory phases) as the within-individual factor. The menstrual cycle did not show a significant correlation with urinary 8-OHdG levels. On the other hand, the menstrual cycle-adjusted 8-OHdG level was significantly higher in those with depressive symptoms (7.01ng/mL) than in those without them (3.98ng/mL). The ROC curve analysis showed that urinary 8-OHdG levels had reasonably high discriminative performance throughout all the menstrual cycles (0.73-0.81;all p＜0.05). These results indicated the presence of oxidative stress in subjects with depressive symptoms independent of the menstrual cycle. en-copyright= kn-copyright= en-aut-name=IidaTadayuki en-aut-sei=Iida en-aut-mei=Tadayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=InoueKen en-aut-sei=Inoue en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ItoYasuhiro en-aut-sei=Ito en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshikawaHiroaki en-aut-sei=Ishikawa en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KagionoMiwa en-aut-sei=Kagiono en-aut-mei=Miwa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TeradairaRyoji en-aut-sei=Teradaira en-aut-mei=Ryoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ChikamuraChiho en-aut-sei=Chikamura en-aut-mei=Chiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HaradaToshihide en-aut-sei=Harada en-aut-mei=Toshihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=EzoeSatoko en-aut-sei=Ezoe en-aut-mei=Satoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YatsuyaHiroshi en-aut-sei=Yatsuya en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=Department of Physical Therapy, Faculty of Health and Welfare, Department of Prefectural University of Hiroshima affil-num=2 en-affil= kn-affil=Department of Public Health, Faculty of Medicine, Shimane University affil-num=3 en-affil= kn-affil=Health Sciences, Fujita Health University, affil-num=4 en-affil= kn-affil=Health Sciences, Fujita Health University, affil-num=5 en-affil= kn-affil=Gifu University of Medical Science affil-num=6 en-affil= kn-affil=Health Sciences, Fujita Health University, affil-num=7 en-affil= kn-affil=Attached Clinic, Department of Prefectural University of Hiroshima affil-num=8 en-affil= kn-affil=Department of Physical Therapy, Faculty of Health and Welfare, Department of Prefectural University of Hiroshima affil-num=9 en-affil= kn-affil=Shimane University Health Service Center Izumo affil-num=10 en-affil= kn-affil=Department of Public Health, Fujita Health University School of Medicine en-keyword=depression kn-keyword=depression en-keyword=8-OHdG kn-keyword=8-OHdG en-keyword=menstrual cycle kn-keyword=menstrual cycle END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20140131 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Bright Side and Dark Side of Workplace Social Capital: Opposing Effects of Gender on Overweight among Japanese Employees en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: A growing number of studies have sought to examine the health associations of workplace social capital; however, evidence of associations with overweight is sparse. We examined the association between individual perceptions of workplace social capital and overweight among Japanese male and female employees. Methodology/Principal Findings: We conducted a cross-sectional survey among full-time employees at a company in Osaka prefecture in February 2012. We used an 8-item measure to assess overall and sub-dimensions of workplace social capital, divided into tertiles. Of 1050 employees, 849 responded, and 750 (624 men and 126 women) could be linked to annual health check-up data in the analysis. Binomial logistic regression models were used to calculate odds ratios and 95% confidence intervals for overweight (body mass index: >= 25 kg/m(2), calculated from measured weight and height) separately for men and women. The prevalence of overweight was 24.5% among men and 14.3% among women. Among men, low levels of bonding and linking social capital in the workplace were associated with a nearly 2-fold risk of overweight compared to high corresponding dimensions of social capital when adjusted for age, sleep hours, physiological distress, and lifestyle. In contrast, among women we found lower overall and linking social capital to be associated with lower odds for overweight even after covariate adjustment. Subsequently, we used multinomial logistic regression analyses to assess the relationships between a 1 standard deviation (SD) decrease in mean social capital and odds of underweight/overweight relative to normal weight. Among men, a 1-SD decrease in overall, bonding, and linking social capital was significantly associated with higher odds of overweight, but not with underweight. Among women, no significant associations were found for either overweight or underweight. Conclusions/Significance: We found opposite gender relationships between perceived low linking workplace social capital and overweight among Japanese employees. en-copyright= kn-copyright= en-aut-name=KobayashiTomoko en-aut-sei=Kobayashi en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiEtsuji en-aut-sei=Suzuki en-aut-mei=Etsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OksanenTuula en-aut-sei=Oksanen en-aut-mei=Tuula kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawachiIchiro en-aut-sei=Kawachi en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Dept Epidemiol, Grad Sch Med Dent & Pharmaceut Sci affil-num=2 en-affil= kn-affil=Okayama Univ, Dept Epidemiol, Grad Sch Med Dent & Pharmaceut Sci affil-num=3 en-affil= kn-affil=Finnish Inst Occupat Hlth, Ctr Expertise Dev Work & Org affil-num=4 en-affil= kn-affil=Harvard Univ, Sch Med, Dept Social & Behav Sci affil-num=5 en-affil= kn-affil=Okayama Univ, Dept Epidemiol, Grad Sch Med Dent & Pharmaceut Sci END start-ver=1.4 cd-journal=joma no-vol=126 cd-vols= no-issue=2 article-no= start-page=127 end-page=131 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20140801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Fermented persimmon extract (kaki-shibu) is useful as a standard for component analyses of persimmon phytobezoars kn-title=柿胃石の成分分析における標準物質としての柿渋の有用性 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The definite diagnosis of persimmon phytobezoar (i.e., diospyrobezoar) is often accomplished by a component analysis using infrared spectroscopy. However, no studies have been conducted to investigate which substance is the best as a standard for the component analysis. Here we analyzed tannic acid, Japanese persimmon (kaki), fermented persimmon extract (kaki-shibu), conventional dried persimmon, and dried persimmon smoked in sulfur (ampo-kaki) by infrared spectroscopy to determine which would be optimal as a component analysis standard. The spectrum between 1,600 to 600cm−1 of a persimmon phytobezoar was quite similar to the spectrum of kaki-shibu rather than that of tannic acid. Consequently, we conclude that kaki-shibu should be used as a standard for infrared spectroscopy analyses of persimmon phytobezoars. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name=岩室雅也 kn-aut-sei=岩室 kn-aut-mei=雅也 aut-affil-num=1 ORCID= en-aut-name=OkamotoYuko en-aut-sei=Okamoto en-aut-mei=Yuko kn-aut-name=岡本裕子 kn-aut-sei=岡本 kn-aut-mei=裕子 aut-affil-num=2 ORCID= en-aut-name=MurataToshihiro en-aut-sei=Murata en-aut-mei=Toshihiro kn-aut-name=村田年弘 kn-aut-sei=村田 kn-aut-mei=年弘 aut-affil-num=3 ORCID= en-aut-name=KawaiYoshinari en-aut-sei=Kawai en-aut-mei=Yoshinari kn-aut-name=河合良成 kn-aut-sei=河合 kn-aut-mei=良成 aut-affil-num=4 ORCID= en-aut-name=ShirahaHidenori en-aut-sei=Shiraha en-aut-mei=Hidenori kn-aut-name=白羽英則 kn-aut-sei=白羽 kn-aut-mei=英則 aut-affil-num=5 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name=岡田裕之 kn-aut-sei=岡田 kn-aut-mei=裕之 aut-affil-num=6 ORCID= en-aut-name=YamamotoKazuhide en-aut-sei=Yamamoto en-aut-mei=Kazuhide kn-aut-name=山本和秀 kn-aut-sei=山本 kn-aut-mei=和秀 aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 消化器・肝臓内科学 affil-num=2 en-affil= kn-affil=井原市立井原市民病院　内科 affil-num=3 en-affil= kn-affil=尾道市立市民病院 外科 affil-num=4 en-affil= kn-affil=尾道市立市民病院 消化器内科 affil-num=5 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 消化器・肝臓内科学 affil-num=6 en-affil= kn-affil=岡山大学病院　光学医療診療部 affil-num=7 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 消化器・肝臓内科学 en-keyword=柿胃石（gastric phytobezoar） kn-keyword=柿胃石（gastric phytobezoar） en-keyword=タンニン酸（tannic acid） kn-keyword=タンニン酸（tannic acid） en-keyword=消化管異物（gastrointestinal foreign body） kn-keyword=消化管異物（gastrointestinal foreign body） en-keyword=成分分析（component analysis） kn-keyword=成分分析（component analysis） END start-ver=1.4 cd-journal=joma no-vol=83 cd-vols= no-issue=8 article-no= start-page=1322 end-page=1329 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=199208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Ethane dimethane sulphonate (EDS) 投与によるラット造精機能障害およびその防御的薬剤の検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=SD系雄性ラットにLeydig細胞を直接障害するEDSを投与し,ラット精巣障害の基礎的検討を行い,さらにその防御的役割を果たすと考えられる薬剤を使用,精巣障害に対する防御的効果を検討した.1) EDS投与により精細管内TおよびDHT濃度は有意に低下し,さらに著明な精子形成障害をきたし,EDS投与ラットはホルモン依存性不妊ラットモデルとして適している事が判明した.2) hCG投与およびT microcrystal suspension (Tmcs)精巣内注入により,EDS投与ラットの精細管障害を防御することが可能であり,精細管内T濃度も増加を認めた.3) testosterone propionate (TP)投与は精細管内T, DHT濃度を著明に低下させるにもかかわらず,EDS投与ラットの精細管障害を防御することが判明した.4)精細管内ではTは精子形成に重要な役割を果たす因子の一つであることが示唆された.さらに精卵内Tmcs注入療法,すなわち男性ホルモンペレット移植療法は,一部の特発性男性不妊症に対して有用な治療法であると考えられた en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=永井敦 kn-aut-sei=永井 kn-aut-mei=敦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=5 article-no= start-page=760 end-page=766 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=201210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mizoribine, tacrolimus, and corticosteroid combination therapy successfully induces remission in patients with lupus nephritis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Conventional cyclophosphamide-based treatment regimens for lupus nephritis (LN) are still not considered to be optimal. The aim of this study was to evaluate the efficacy and safety of mizoribine, tacrolimus, and corticosteroid combination therapy for LN. We retrospectively evaluated a combination treatment of mizoribine and tacrolimus with corticosteroids as induction therapy in eight newly diagnosed systemic lupus erythematosus (SLE) patients with biopsy-proven LN. All patients were women, and their mean [standard deviation (SD)] age was 48.5 (20) years. All patients (100 %) had positive anti-double-stranded DNA (anti-dsDNA) antibody titers, and four (50.0 %) were nephrotic. Mean (SD) serum creatinine and daily proteinuria levels were 0.72 (0.4) mg/dl (range 0.33-1.55 mg/dl) and 4.56 (2.8) g (range 0.77-8.2 g), respectively. By month 2, significant improvements in the anti-dsDNA antibody titers, levels of proteinuria, serum albumin, and C3, and SLE disease activity index score were observed. By month 6, seven patients (87.5 %) were in complete remission, with normalized levels of both proteinuria and serum creatinine. This pilot study suggests that mizoribine and tacrolimus treatment with corticosteroids is well tolerated and may prove to be an optimal alternative remission-inducing regimen for LN. en-copyright= kn-copyright= en-aut-name=KagawaHidetoshi en-aut-sei=Kagawa en-aut-mei=Hidetoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiromasaTsutomu en-aut-sei=Hiromasa en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaraTakayuki en-aut-sei=Hara en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakakiAyako en-aut-sei=Takaki en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamanakaRyutaro en-aut-sei=Yamanaka en-aut-mei=Ryutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SadaKen-ei en-aut-sei=Sada en-aut-mei=Ken-ei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MakinoHirofumi en-aut-sei=Makino en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=Himeji Red Cross Hosp, Dept Internal Med affil-num=2 en-affil= kn-affil=Himeji Red Cross Hosp, Dept Internal Med affil-num=3 en-affil= kn-affil=Himeji Red Cross Hosp, Dept Internal Med affil-num=4 en-affil= kn-affil=Himeji Red Cross Hosp, Dept Internal Med affil-num=5 en-affil= kn-affil=Himeji Red Cross Hosp, Dept Internal Med affil-num=6 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Med & Clin Sci affil-num=7 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Med & Clin Sci en-keyword=Induction therapy kn-keyword=Induction therapy en-keyword=Lupus nephritis kn-keyword=Lupus nephritis en-keyword=Mizoribine kn-keyword=Mizoribine en-keyword=Multitarget therapy kn-keyword=Multitarget therapy en-keyword=Systemic lupus erythematosus kn-keyword=Systemic lupus erythematosus en-keyword=Tacrolimus kn-keyword=Tacrolimus END start-ver=1.4 cd-journal=joma no-vol=126 cd-vols= no-issue=1 article-no= start-page=49 end-page=54 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20140401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Molecular targeted therapies in leukemia kn-title=白血病および白血病類縁疾患における分子標的治療 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name=前田嘉信 kn-aut-sei=前田 kn-aut-mei=嘉信 aut-affil-num=1 ORCID= en-aut-name=TanimotoMitsune en-aut-sei=Tanimoto en-aut-mei=Mitsune kn-aut-name=谷本光音 kn-aut-sei=谷本 kn-aut-mei=光音 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学病院　血液・腫瘍内科 affil-num=2 en-affil= kn-affil=岡山大学病院　血液・腫瘍内科 en-keyword=白血病 kn-keyword=白血病 en-keyword=分子標的薬 kn-keyword=分子標的薬 en-keyword=チロシンキナーゼ阻害薬 kn-keyword=チロシンキナーゼ阻害薬 END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue= article-no= start-page=1 end-page=4 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20140201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=大豆発芽時期におけるグリシニン分解酵素の活性変動 kn-title=Changes in Glycinin?Digesting Protease Activity During Soybean Germination. en-subtitle= kn-subtitle= en-abstract=　大豆発芽期におけるグリシニン分解酵素 (98 kDa SBP) の活性変動を解析した．大豆種子を４時間水で膨潤後， 25 ℃ 暗黒下で発芽させた．経時的にサンプリングを行い，2M NaCl を含むトリス緩衝液 (? 7.0) により粗酵素を抽出 後，グリシニン由来のトリプシン分解ペプチドを基質としてグリシニン分解酵素の活性変動を逆相 HPLC により追 跡した．その結果，種子膨潤後４日間比活性はほぼ一定の値を保ち，以後徐々に低下することが分かった．次いで， 粗酵素溶液からイオン交換 HPLC により98 kDa SBP を部分精製するとともに，発芽期における 98 kDa SBP の消長 を解析したところ，98 kDa SBP は乾燥種子及び各発芽段階の種子中全てに認められ，かつグリシン分解活性もグリ シニン由来のトリプシン分解ペプチド基質に対する活性と同様に認められた．以上の結果から，98 kDa SBP は種子 発芽に伴い誘導されるプロテアーゼではなく，種子貯蔵型のプロテアーゼであることが明らかになった． kn-abstract=　Changes in glycinin-digesting protease activity during soybean germination have been investigated.

Recently, ferritin is pointed out to be related with oxidative stress. However, there is still no population research which showed the relation of CP and ferritin. Therefore, we investigated the relationship between CP and ferritin including oxidative stress biomarkers among healthy Japanese (n = 389). We measured serum CP, ferritin, Fe, high-sensitivity C-reactive protein (hs-CRP), and urinary oxidative stress biomarkers [H2O2, 8-hydroxy-2'-deoxyguanosine (8-OHdG), 8-isoprostane] and so on. Subjects showed that age; 41.7 ± 10.0 (year), CP; 31.9 ± 6.8 (mg/dl), ferritin; 123.5 ± 121.0 (ng/ml), hs-CRP; 0.89 ± 2.53 (mg/l), 8-OHdG; 10.2 ± 4.4 [ng/mg creatinine (Cre)] and H2O2; 6.5 ± 10.9 (?M/g Cre), (All data mentioned above were expressed as mean ± SD). CP was significantly and positively correlated with hs-CRP and inversely correlated with ferritin, Fe and 8-OHdG. By a multiple logistic regression analysis, odds ratio of CP according to quartiles of hs-CRP was 4.86, and according to quartiles of 8-OHdG was 0.39 after adjusting for age and other confounding factors. In conclusion, our findings suggest that CP was an antioxidative biomarker which controls oxidative stress, whereas ferritin was a marker which may participate in the generation of oxidative stress. en-copyright= kn-copyright= en-aut-name=InoueKiyomi en-aut-sei=Inoue en-aut-mei=Kiyomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakanoNoriko en-aut-sei=Sakano en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OginoKeiki en-aut-sei=Ogino en-aut-mei=Keiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatoYoshie en-aut-sei=Sato en-aut-mei=Yoshie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WangDa-Hong en-aut-sei=Wang en-aut-mei=Da-Hong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KuboMasayuki en-aut-sei=Kubo en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakahashiHidekazu en-aut-sei=Takahashi en-aut-mei=Hidekazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KanbaraSakiko en-aut-sei=Kanbara en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MiyatakeNobuyuki en-aut-sei=Miyatake en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil= kn-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=2 en-affil= kn-affil=Department of Hygiene, Faculty of Medicine, Kagawa University affil-num=3 en-affil= kn-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=4 en-affil= kn-affil=Perineito Hahatokono Hosp Mothers & Children, Dept Gynecol & Obstet affil-num=5 en-affil= kn-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=6 en-affil= kn-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=7 en-affil= kn-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=8 en-affil= kn-affil=Okayama Univ, Dept Pediat, Grad Sch Med Dent & Pharmaceut Sci affil-num=9 en-affil= kn-affil=Department of Hygiene, Faculty of Medicine, Kagawa University en-keyword=ceruloplasmin kn-keyword=ceruloplasmin en-keyword=ferritin kn-keyword=ferritin en-keyword=8-OHdG kn-keyword=8-OHdG en-keyword=oxidative stress kn-keyword=oxidative stress en-keyword=high-sensitivity C-reactive protein kn-keyword=high-sensitivity C-reactive protein END start-ver=1.4 cd-journal=joma no-vol=125 cd-vols= no-issue=2 article-no= start-page=159 end-page=162 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20130801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Guidelines for treatment of ischemic stroke kn-title=脳梗塞の治療ガイドライン en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=DeguchiKentaro en-aut-sei=Deguchi en-aut-mei=Kentaro kn-aut-name=出口健太郎 kn-aut-sei=出口 kn-aut-mei=健太郎 aut-affil-num=1 ORCID= en-aut-name=AbeKoji en-aut-sei=Abe en-aut-mei=Koji kn-aut-name=阿部康二 kn-aut-sei=阿部 kn-aut-mei=康二 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学病院 神経内科 affil-num=2 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 神経内科学 END start-ver=1.4 cd-journal=joma no-vol=52 cd-vols= no-issue=1 article-no= start-page=27 end-page=31 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20130101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Thioredoxin-1 and oxidative stress status in pregnant women at early third trimester of pregnancy: relation to maternal and neonatal characteristics en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study examined the clinical and biological importance of thioredoxin-1, a redox-active defensive protein that controls multiple biological functions, in pregnant women. We measured serum concentrations of thioredoxin-1, total hydroperoxides, and redox potential in 60 pregnant women at the early third trimester: gestational age of 27-29 weeks. The thioredoxin-1 concentration (mean +/- SD) was 90 +/- 42 ng/ml. Total hydroperoxides was 471 +/- 105 U.CARR (1 U.CARR = 0.08 mg/dl H2O2). Redox potential was 2142 +/- 273 mu mol/l. The total hydroperoxides: redox potential ratio (oxidative stress index) was 0.23 +/- 0.08. Thioredoxin-1, total hydroperoxides, and oxidative stress index were higher and redox potential was lower than in blood of healthy adults. Total hydroperoxides and redox potential were mutually correlated significantly and negatively. Thioredoxin-1 correlated significantly and negatively and redox potential correlated significantly and positively with body weight and body mass index. Thioredoxin-1 and redox potential correlated significantly and positively with uric acid and albumin, respectively. Thioredoxin-1 and oxidative stress index correlated significantly and negatively and redox potential significantly and positively with neonatal birth weight. These results suggest that high concentrations of thioredoxin-1 are linked to high oxidative stress status in pregnant women and that neonatal birth weight is affected by the maternal oxidative condition during later pregnancy. en-copyright= kn-copyright= en-aut-name=NakatsukasaYoko en-aut-sei=Nakatsukasa en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

the structures of the HA complexes produced by Clostridium botulinum type A mutant strain kn-title=ボツリヌスＡ型菌変異株が産生するHA複合体の構造に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Clostridium botulinum produces seven neurotoxin (NTX) serotypes, classified from as A to G. In culture, NTX forms protein complexes by association with non-toxic components, such as nontoxic-nonhemagglutinin (NTNH) and hemagglutinins (HA1, HA2, HA3). C. botulinum serotype A produces three types of toxin complexes, M-toxin (NTX and NTNH), L-toxin (M-toxin and HAs) and LL-toxin (dimer of L-toxin). In this study, I found three HA complexes in the culture of a nontoxigenic mutant serotype A lacking ntx and ntnh expression. The HA complexes displayed similar banding patterns on SDS-PAGE, but the staining intensities of the HA1 and HA2 bands were different. In addition, their native-PAGE banding profiles exhibited different behaviors. The large-molecular-size HA complex showed the highest activity, similar to that of an L-toxin. Based on the combined results of the PAGE and gel-filtration profiles, the differences in molecular size among the three HA complexes were thought to be caused by different numbers of HA1 and HA2 molecules. This paper reports for the first time the purification and characterization of a native HA complex of serotype A, and suggests that the HA can form complex structures without NTX and NTNH. This may help in understanding the toxin complex assembly pathway. en-copyright= kn-copyright= en-aut-name=MaShaobo en-aut-sei=Ma en-aut-mei=Shaobo kn-aut-name=馬少博 kn-aut-sei=馬 kn-aut-mei=少博 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　病原細菌学 en-keyword=ボツリヌス毒素（botulinum toxin） kn-keyword=ボツリヌス毒素（botulinum toxin） en-keyword=ボツリヌス菌（Clostridium botulinum） kn-keyword=ボツリヌス菌（Clostridium botulinum） en-keyword=血球凝集素（hemagglutinin） kn-keyword=血球凝集素（hemagglutinin） en-keyword=タンパク質複合体構造（protein complex structure） kn-keyword=タンパク質複合体構造（protein complex structure） END start-ver=1.4 cd-journal=joma no-vol=124 cd-vols= no-issue=2 article-no= start-page=125 end-page=127 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=20120801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Trend of liver and small bowel transplantation in Japan kn-title=日本の肝・小腸移植の動向 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=YagiTakahito en-aut-sei=Yagi en-aut-mei=Takahito kn-aut-name=八木孝仁 kn-aut-sei=八木 kn-aut-mei=孝仁 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学病院 肝胆膵外科 en-keyword=liver kn-keyword=liver en-keyword=small bowel kn-keyword=small bowel en-keyword=transplantation kn-keyword=transplantation en-keyword=deceased donor kn-keyword=deceased donor END start-ver=1.4 cd-journal=joma no-vol=66 cd-vols= no-issue=3 article-no= start-page=191 end-page=201 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=201206 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Time Trade-off Utility Analysis for Surgical Intervention in Comitant Strabismus, Glaucoma, and Cataract en-subtitle= kn-subtitle= en-abstract= kn-abstract=The utility value was compared among 3 surgical interventions, and the validity of the time trade-off (TTO) method was evaluated by analyzing the correlations of the utility value with the results of the Visual Function Questionnaire-14 (VF-14) and other variables. The subjects were 127 patients aged 40-85 years who were surgically treated between January 2008 and March 2010, including 26 patients with glaucoma, 50 with cataracts, and 51 with comitant strabismus. The scores on VF-14 and utility values determined using TTO were calculated retrospectively. The mean value (SD) of the utility gain was 0.096 (0.105) for glaucoma, 0.101 (0.105) for comitant strabismus, and 0.167 (0.237) for unilateral and 0.245 (0.167) for bilateral cataracts, indicating significant postoperative improvements in the utility value. A significant correlation was observed between the utility value and the postoperative VF-14 scores of the bilateral cataracts, and the postoperative visual acuity of the better eye of the unilateral cataract. The mean value of the quality-adjusted life years was 2.181 for bilateral and 1.424 for unilateral cataracts, 1.132 for strabismus, and 0.870 for glaucoma with an annual discount rate of 3%. The gain of utility value was highest in bilateral cataracts, and lowest in glaucoma, and thus the TTO analysis was considered to be highly valid for cataract surgery. en-copyright= kn-copyright= en-aut-name=KishimotoFumiko en-aut-sei=Kishimoto en-aut-mei=Fumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaitoTomoko en-aut-sei=Naito en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HasebeSatoshi en-aut-sei=Hasebe en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OhtsukiHiroshi en-aut-sei=Ohtsuki en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine affil-num=2 en-affil= kn-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine affil-num=3 en-affil= kn-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine affil-num=4 en-affil= kn-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine en-keyword=surgical intervention kn-keyword=surgical intervention en-keyword=VF-14 kn-keyword=VF-14 en-keyword=utility analysis kn-keyword=utility analysis en-keyword=time trade-off kn-keyword=time trade-off en-keyword=quality-adjusted life years kn-keyword=quality-adjusted life years END start-ver=1.4 cd-journal=joma no-vol=101 cd-vols= no-issue= article-no= start-page=1 end-page=6 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=20120201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Purification and Characterization of Thermostable Amidase from Thermus sp.O-3-1 kn-title=好熱性細菌Thermus sp.O-3-1由来耐熱性アミダーゼの精製及び性質検討 en-subtitle= kn-subtitle= en-abstract=好熱性細菌Thermus sp.O-3-1 由来の耐熱性アミダーゼ遺伝子を大腸菌中にクローニングし，その塩基配列を決定した．ami 遺伝子は930 bp からなり，310アミノ酸をコードしていた．本酵素の分子量は33，089 Daであると予想された．Thermus sp.O-3-1 由来アミダーゼを大腸菌で生産させ，熱処理とDEAE-トヨパール650M陰イオン交換カラム等により精製した．ゲル濾過クロマトグラフィーとSDS-PAGE の結果から本酵素は分子質量33 kDa のサブユニット2分子からなるダイマー構造を有していることが明らかとなった．精製酵素の熱安定性は80℃まで，pH 安定性は7.0〜10.0であり，安定性の 高い酵素であった．最適温度は90℃，最適 pH は9.0であ った．EDTA により活性が著しく阻害され，Co(2+)やNi(2+)，Mn(2+)によって活性の回復，向上が見られたため，本酵素は金属酵素であることが示唆された．基質特異性の検討 の結果，L-Leu-pNA よりもD-Leu-pNA に対して高い活性を示したため，本酵素がＤ-アミノ酸基質に特異性を持つアミダーゼであることが判明した．本酵素は耐熱性を有するユニークなＤ-アミノ酸アミダーゼであり，今後産業利用が期待される． kn-abstract=The gene encoding a thermostable amidase (EC 3.5.1.4) from thermophilic bacterium Thermus sp.O-3-1, was cloned and expressed in Escherichia coli JM109. The cloned amidase gene (ami) is 930 bp and encodes a protein composed of 310 amino acids. The protein is predicted to have a molecular mass of 33,089 Da. The amidase from Thermus sp.O-3-1 was purified by heat treatment and DEAE Toyopearl 650M column chromatography. The molecular mass of the native enzyme was estimated to be about 70 kDa by gel filtration chromatography, indicating that the enzyme has a homodimeric structure. The purified enzyme was stable up to 80°C and within a pH range from 7.0 to 10.0. The optimum temperature and pH for enzyme activity were 90°C, and 9.0, respectively. The enzyme was strongly inhibited by the metal-chelating compound EDTA. The activity of the EDTA-treated enzyme was reactivated by the addition of Co(2+), Ni(2+) and Mn(2+) ions. Therefore the enzyme was predicted to be metalloenzyme. Finally, as a result of investigation into substrate specificity, the purified enzyme was suggested to be D-amino acid specific amidase, as it showed higher activity toward D-Leu-pNA than L-Leu-pNA. en-copyright= kn-copyright= en-aut-name=KobayashiFumiaki en-aut-sei=Kobayashi en-aut-mei=Fumiaki kn-aut-name=小林史明 kn-aut-sei=小林 kn-aut-mei=史明 aut-affil-num=1 ORCID= en-aut-name=AomineHiroki en-aut-sei=Aomine en-aut-mei=Hiroki kn-aut-name=青峰弘起 kn-aut-sei=青峰 kn-aut-mei=弘起 aut-affil-num=2 ORCID= en-aut-name=MizunashiWataru en-aut-sei=Mizunashi en-aut-mei=Wataru kn-aut-name=水無渉 kn-aut-sei=水無 kn-aut-mei=渉 aut-affil-num=3 ORCID= en-aut-name=YuFujio en-aut-sei=Yu en-aut-mei=Fujio kn-aut-name=湯不二夫 kn-aut-sei=湯 kn-aut-mei=不二夫 aut-affil-num=4 ORCID= en-aut-name=TamuraTakashi en-aut-sei=Tamura en-aut-mei=Takashi kn-aut-name=田村隆 kn-aut-sei=田村 kn-aut-mei=隆 aut-affil-num=5 ORCID= en-aut-name=InagakiKenji en-aut-sei=Inagaki en-aut-mei=Kenji kn-aut-name=稲垣賢二 kn-aut-sei=稲垣 kn-aut-mei=賢二 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil=(株)三菱レイヨン affil-num=4 en-affil= kn-affil= affil-num=5 en-affil= kn-affil=岡山大学 affil-num=6 en-affil= kn-affil=岡山大学 en-keyword=amidase kn-keyword=amidase en-keyword=thermostable enzyme kn-keyword=thermostable enzyme en-keyword=Thermus kn-keyword=Thermus en-keyword=D-amino acid specific amidase kn-keyword=D-amino acid specific amidase END start-ver=1.4 cd-journal=joma no-vol=123 cd-vols= no-issue=3 article-no= start-page=231 end-page=235 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=20111201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Japanese guidelines for the diagnosis and management of soft tissue tumor kn-title=軟部腫瘍診療ガイドライン en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MorimotoYuki en-aut-sei=Morimoto en-aut-mei=Yuki kn-aut-name=森本裕樹 kn-aut-sei=森本 kn-aut-mei=裕樹 aut-affil-num=1 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name=尾ｱ敏文 kn-aut-sei=尾ｱ kn-aut-mei=敏文 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学病院　整形外科 affil-num=2 en-affil= kn-affil=岡山大学病院　整形外科 END start-ver=1.4 cd-journal=joma no-vol=56 cd-vols= no-issue=8 article-no= start-page=768 end-page=774 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=201108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of exercise training on gingival oxidative stress in obese rats en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: The purpose of the present study was to investigate the effects of exercise training on serum reactive oxygen species (ROS) level and gingival oxidative stress in obese rats fed a high-fat diet. Design: Rats were divided into three groups (n = 14/group): one control group (fed a regular diet) and two experimental groups (fed a high-fat diet with and without exercise training [treadmill: 5 days/week]). The rats were sacrificed at 4 or 8 weeks. The level of serum reactive oxidative metabolites (ROM) was measured as an indicator of circulating ROS. The level of 8-hydroxydeoxyguanosine (8-OHdG) and reduced-form glutathione (GSH)/oxidised-form glutathione (GSSG) ratio were determined to evaluate gingival oxidative stress. Results: The obese rats fed a high-fat diet without exercise training showed higher serum ROM levels [Carratelli Units (CARR U)] (mean +/- SD; 413 +/- 64) than the control (333 +/- 12) at 4 weeks (p = 0.023). Such a condition resulted in higher 8-OHdG levels (ng/mg mtDNA) (0.97 +/- 0.18) (p < 0.05) and a lower GSH/GSSG ratio (17.0 +/- 3.1) (p < 0.05) in gingival tissues, compared to the control (0.55 +/- 0.13 for 8-OHdG and 23.6 +/- 5.8 for GSH/GSSG ratio) at 8 weeks. In addition, the obese rats fed a high-fat diet with exercise training showed lower serum ROM (623 +/- 103) (p<0.001) and gingival 8-OHdG levels (0.69 +/- 0.17) (p = 0.012) than those without exercise training (1105 95 for ROM and 0.55 +/- 0.13 for 8-OHdG) at 8 weeks. Conclusions: Obesity prevention by exercise training may effectively suppress gingival oxidative stress by decreasing serum ROS in rats. en-copyright= kn-copyright= en-aut-name=AzumaTetsuji en-aut-sei=Azuma en-aut-mei=Tetsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TomofujiTakaaki en-aut-sei=Tomofuji en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EndoYasumasa en-aut-sei=Endo en-aut-mei=Yasumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TamakiNaofumi en-aut-sei=Tamaki en-aut-mei=Naofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IrieKoichiro en-aut-sei=Irie en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KasuyamaKenta en-aut-sei=Kasuyama en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KatoTomo en-aut-sei=Kato en-aut-mei=Tomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil= kn-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=2 en-affil= kn-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=3 en-affil= kn-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=4 en-affil= kn-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=5 en-affil= kn-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=6 en-affil= kn-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=7 en-affil= kn-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=8 en-affil= kn-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=9 en-affil= kn-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences en-keyword=Obesity kn-keyword=Obesity en-keyword=Exercise training kn-keyword=Exercise training en-keyword=Periodontal diseases kn-keyword=Periodontal diseases en-keyword=Oxidative stress kn-keyword=Oxidative stress END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=4 article-no= start-page=231 end-page=237 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=201108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical Efficacy of Capecitabine and Cyclophosphamide (XC) in Patients with Metastatic Breast Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Combined low-dose therapy of oral capecitabine (Xeloda) and cyclophosphamide (XC) has been demonstrated to be useful for long-term control of lesions in patients with metastatic breast cancer (MBC) and is aimed at symptomatic alleviation and prolongation of survival. Here, a retrospective review was conducted of MBC patients administered XC at the Okayama University Hospital (OUH), to evaluate responses to XC, adverse events and time to progression (TTP). Twenty patients with MBC received XC between 2006 and 2009. With the exception of 2 elderly patients who were over the age of 70 at the initial examination, all of the patients had received prior treatment with an anthracycline and/or a taxane. No complete response (CR) cases were observed, but partial response (PR) was achieved in 6 patients (30%) and SD in 9 (45%), of whom 5 (20%) sustained SD status for >12 months. The median TTP was 6 months (range:3-27 mo.). Three patients developed Grade 3 adverse events (diarrhea, nausea and stomatitis), but no other patients developed adverse reactions causing interruption of the therapy. XC was safe even in previously treated and elderly MBC patients;moreover, it yielded remarkable clinical responses. en-copyright= kn-copyright= en-aut-name=ShienTadahiko en-aut-sei=Shien en-aut-mei=Tadahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=NishiyamaKeiko en-aut-sei=Nishiyama en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MasudaHiroko en-aut-sei=Masuda en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=IkedaHirokuni en-aut-sei=Ikeda en-aut-mei=Hirokuni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil= kn-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital affil-num=2 en-affil= kn-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital affil-num=3 en-affil= kn-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital affil-num=4 en-affil= kn-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital affil-num=5 en-affil= kn-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital affil-num=6 en-affil= kn-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital affil-num=7 en-affil= kn-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital en-keyword=metastatic breast cancer kn-keyword=metastatic breast cancer en-keyword=metronomic kn-keyword=metronomic en-keyword=chemotherapy kn-keyword=chemotherapy END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=3 article-no= start-page=403 end-page=410 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=201105 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characterization of an OmpA-like outer membrane protein of the acidophilic iron-oxidizing bacterium, Acidithiobacillus ferrooxidans en-subtitle= kn-subtitle= en-abstract= kn-abstract=An OmpA family protein (FopA) previously reported as one of the major outer membrane proteins of an acidophilic iron-oxidizing bacterium Acidithiobacillus ferrooxidans was characterized with emphasis on the modification by heat and the interaction with peptidoglycan. A 30-kDa band corresponding to the FopA protein was detected in outer membrane proteins extracted at 75A degrees C or heated to 100A degrees C for 10 min prior to sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). However, the band was not detected in outer membrane proteins extracted at a parts per thousand currency sign40A degrees C and without boiling prior to electrophoresis. By Western blot analysis using the polyclonal antibody against the recombinant FopA, FopA was detected as bands with apparent molecular masses of 30 and 90 kDa, suggesting that FopA existed as an oligomeric form in the outer membrane of A. ferrooxidans. Although the fopA gene with a sequence encoding the signal peptide was successfully expressed in the outer membrane of Escherichia coli, the recombinant FopA existed as a monomer in the outer membrane of E. coli. FopA was detected in peptidoglycan-associated proteins from A. ferrooxidans. The recombinant FopA also showed the peptidoglycan-binding activity. en-copyright= kn-copyright= en-aut-name=ManchurMohammed Abul en-aut-sei=Manchur en-aut-mei=Mohammed Abul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KikumotoMei en-aut-sei=Kikumoto en-aut-mei=Mei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanaoTadayoshi en-aut-sei=Kanao en-aut-mei=Tadayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakadaJun en-aut-sei=Takada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KamimuraKazuo en-aut-sei=Kamimura en-aut-mei=Kazuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=Division of Bioscience, Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Division of Bioscience, Graduate School of Natural Science and Technology, Okayama University affil-num=3 en-affil= kn-affil=Division of Bioscience, Graduate School of Natural Science and Technology, Okayama University affil-num=4 en-affil= kn-affil=Division of Chemical and Biological Technology, Graduate School of Natural Science and Technology, Okayama University affil-num=5 en-affil= kn-affil=Division of Bioscience, Graduate School of Natural Science and Technology, Okayama University en-keyword=Acidithiobacillus ferrooxidans kn-keyword=Acidithiobacillus ferrooxidans en-keyword=Iron-oxidizing bacterium kn-keyword=Iron-oxidizing bacterium en-keyword=Acidophile kn-keyword=Acidophile en-keyword=Outer membrane protein kn-keyword=Outer membrane protein en-keyword=OmpA kn-keyword=OmpA END start-ver=1.4 cd-journal=joma no-vol=123 cd-vols= no-issue=2 article-no= start-page=85 end-page=89 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=20110801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Hepatic toxicity and prognosis in HCV-infected patients with diffuse large B-cell lymphoma in the rituximab era kn-title=HCV感染がRCHOP療法下でのDLBCLにおける 肝障害と予後に与える影響 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name=遠西大輔 kn-aut-sei=遠西 kn-aut-mei=大輔 aut-affil-num=1 ORCID= en-aut-name=TanimotoMitsune en-aut-sei=Tanimoto en-aut-mei=Mitsune kn-aut-name=谷本光音 kn-aut-sei=谷本 kn-aut-mei=光音 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　血液・腫瘍・呼吸器内科学 affil-num=2 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　血液・腫瘍・呼吸器内科学 en-keyword=HCV kn-keyword=HCV en-keyword=diffuse large B-cell lymphoma kn-keyword=diffuse large B-cell lymphoma en-keyword=rituximab kn-keyword=rituximab en-keyword=hepatic toxicity kn-keyword=hepatic toxicity END start-ver=1.4 cd-journal=joma no-vol=101 cd-vols= no-issue=11-12 article-no= start-page=1037 end-page=1048 dt-received= dt-revised= dt-accepted= dt-pub-year=1989 dt-pub=198912 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The origin of liver epithelial-like cells derived from the normal rat kn-title=正常ラット肝由来上皮様細胞の起源 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To investigate the origin of liver epithelial-like cells derived from the normal rat, we examined ten liver epithelial-like cell clones. These cultured cells were isolated from clonogenically growing cells in the primary culture. Morphological, cytochemical and biochemical characteristics of these ten of clones showed the followings: (1) These cells consisted of dense, diffuse and intermediate types. (2) Analyses of serum-free conditioned culture media, using SDS-PAGE, demonstrated that the dense type had a certain profile in the group of secretory proteins, whereas the diffuse and intermediate types had varied profiles although the latter were somewhat similar in profile to the dense type. (3) The secretory protein groups were different from mesenchymal cell lines in their profiles. (4) Cytokeratin was present in all the ten of clones. (5) Cytokeratin was also present in the cholangiolar epithelia and cells localized in peripheral areas of normal hepatic lobules. (6) The function, as seen in mature-type hepatocytes and cholangiolar epithelia, was almost absent. (7) These ten clones were different from sinusoidal endothelia according to their morphologies and growth ability in the primary culture. In conclusion, the liver epithelial-like cell clones derived from normal rat can belong to a “stem-cell family” of liver tissue. These “stem cells” may be localized next to the hepatocytes and cholangiolar epithelia in vivo. en-copyright= kn-copyright= en-aut-name=MatsuuraKazuhiko en-aut-sei=Matsuura en-aut-mei=Kazuhiko kn-aut-name=松浦一彦 kn-aut-sei=松浦 kn-aut-mei=一彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部癌源研究施設病理部 en-keyword=ラット kn-keyword=ラット en-keyword=肝細胞培養 kn-keyword=肝細胞培養 en-keyword=上皮様細胞 kn-keyword=上皮様細胞 en-keyword=cytokeratin kn-keyword=cytokeratin en-keyword=stem cell kn-keyword=stem cell END start-ver=1.4 cd-journal=joma no-vol=101 cd-vols= no-issue=7-8 article-no= start-page=687 end-page=698 dt-received= dt-revised= dt-accepted= dt-pub-year=1989 dt-pub=19890831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Purification and characterization of HBs antigen from hepatoma huGK-14 cell line kn-title=ヒト培養肝癌細胞の産生するHBs抗原の精製方法とその物理化学的特性について en-subtitle= kn-subtitle= en-abstract= kn-abstract=HBs antigen was purified from the culture fluid of hepatoma huGK-14 cell line and its physico-chemical properties were studied. The purification consists of following steps: concentration of culture fluid by membrane filtration, affinity column chromatography (anti-HBs monoclonal antibody column and anti-human serum albumin antibody column), and ultracentrifugation (isopycnic centrifugation in CsCl density gradient and rate zonal centrifugation on sucrose gradient). Highly purified (purity>99%) HBs antigen was isolated with an overall yield of about 40%. The HBs antigen showed uniform spherical particles (diameter: 23.2±2.9nm) and had a specific gravity of 1.20g/cm3. The purified HBs antigen yielded, in SDS-PAGE (under reducing conditions), four protein bands with apparent molecular weights of 22,000 and 26,000 (the two major bands), and 44,000 and 47,000. The two proteins of molecular weights of 26,000 and 47,000 are likely to be glycosylated, as these were several fold reduced when the cells were cultured in the presence of Tunicamycin. Amino acid analysis, Edman degradation, carboxypeptidase digestion, and ultraviolet absorption spectrum indicated that the HBs antigen from hepatoma cells is very similar to that derived from human plasma. en-copyright= kn-copyright= en-aut-name=OdaMunehiro en-aut-sei=Oda en-aut-mei=Munehiro kn-aut-name=小田宗宏 kn-aut-sei=小田 kn-aut-mei=宗宏 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部癌源病理学教室 en-keyword=Hepatoma kn-keyword=Hepatoma en-keyword=Cell culture kn-keyword=Cell culture en-keyword=HBs antigen kn-keyword=HBs antigen en-keyword=Purification kn-keyword=Purification en-keyword=Characterization kn-keyword=Characterization END start-ver=1.4 cd-journal=joma no-vol=101 cd-vols= no-issue=5-6 article-no= start-page=659 end-page=672 dt-received= dt-revised= dt-accepted= dt-pub-year=1989 dt-pub=198906 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Expression and purification of the HIV-1 env gene products in Escherichia coli kn-title=HIV-1エンベロープ蛋白質の大腸菌での発現と精製 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To purify the HIV-1 envelope protein with antigenic reactivity, the Pvu II-Bgl II fragment of the HIV-1 env gene, from the Pvu II site to the second Bgl II site, encoding the carboxyl terminal 180 amino acids of the viral surface protein (SU, gp120) was molecularly cloned in Escherichia coli strain HB101 using protein A expression-shuttle vector pRIT5. The pRIT5 contains the protein A gene, encoding the secretion signal and IgG binding domain of protein A with the upstream promoter and the downstream multicloning sites, as well as the two replication sites for Escherichia coli and Staphylococcus aureus. A fused protein with the molecular weight of about 55 kilodaltons was produced, which showed the same reactivity as the native protein A against rabbit serum IgG on Western blotting analysis. Most of the fused protein in the periplasmic space was degraded, while the complete fused protein inside the cells was recovered as an insoluble protein. The fused protein was solubilized with sodium dodecylsulfate (SDS), partially purified by IgG sepharose affinity chromatography, and completely purified by SDS-polyacrylamide gel electrophoresis. The quantity of the expressed fused protein was estimated about 1% of the total proteins. The purified fused protein contained 516 amino acids with Mr54, 976, consisting of 305 amino acids of the IgG binding domain of protein A, 5 amino acids derived from polylinker, a carboxyl terminal 180 amino acids of the HIV-1 envelope surface protein gp120, and 26 amino acids derived from the pUC19 sequence. en-copyright= kn-copyright= en-aut-name=ZhangBo en-aut-sei=Zhang en-aut-mei=Bo kn-aut-name=張波 kn-aut-sei=張 kn-aut-mei=波 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部癌源研究施設生化学部門 en-keyword=HIV-1 kn-keyword=HIV-1 en-keyword=エンベロープ蛋白質 kn-keyword=エンベロープ蛋白質 en-keyword=発現ベクター kn-keyword=発現ベクター en-keyword=Protein A kn-keyword=Protein A en-keyword=IgG-Sepharoseカラム kn-keyword=IgG-Sepharoseカラム END start-ver=1.4 cd-journal=joma no-vol=101 cd-vols= no-issue=1-2 article-no= start-page=201 end-page=212 dt-received= dt-revised= dt-accepted= dt-pub-year=1989 dt-pub=198902 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Structural diversity in flagella of enteropathogenic E. coli kn-title=病原性大腸菌（EPEC）の鞭毛構造の多様性 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The ultrastructure of flagella of enteropathogenic E. coli was analysed by electron microscopy. The flagella of E. coli 0126, 026, 0114 and 0128, each of which have different H antigen types, were tentatively classified into four types according to their ultrastructural similarity. The appearence of most flagella structures were homologous in each H type and identical with a previous report (Lawn, AM, 1977). However, the structure of H31, H25 and H48 were different from the previous ones and H11 (026K60) and H25 (026K60) showed two different types of flagella structure in a single H type. Immuno-electron microscopy using gold-labeled anti-rabbit IgG goat antibody disclosed that there were anti H type sera reactive flagella and non reactive flagella in both Hll and H25, although the molecular weight of each flagellin showed one homologous band by SDS-PAGE. The result suggests that there is a certain diversity in the manner of self assembly of flagellin to form flagella structures. en-copyright= kn-copyright= en-aut-name=FujiiTakashi en-aut-sei=Fujii en-aut-mei=Takashi kn-aut-name=藤井高志 kn-aut-sei=藤井 kn-aut-mei=高志 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部細菌学教室 en-keyword=病原性大腸菌 kn-keyword=病原性大腸菌 en-keyword=鞭毛超微構造 kn-keyword=鞭毛超微構造 en-keyword=H型抗原 kn-keyword=H型抗原 en-keyword=フラジェリン kn-keyword=フラジェリン END start-ver=1.4 cd-journal=joma no-vol=102 cd-vols= no-issue=3-4 article-no= start-page=391 end-page=404 dt-received= dt-revised= dt-accepted= dt-pub-year=1990 dt-pub=199004 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The effects of arterial blood halothane or enflurane concentration on the circulatory system kn-title=ハロセン・エンフルレン麻酔の動脈血中濃度と循環動態に関する実験的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effects of halothane (H) or enflurane (E) concentration on the circulatory system were studied in dogs. Two hours of halothane or enflurane anesthesia resulted in a linear dose-dependent decrease in circulatory indices inculding: mean arterial pressure (mAP), heart rate (HR), cardiac index (CI) and left ventricular peak dp/dt/IP (peak dp/dt/IP). Systemic vascular resistance (SVR) did not change during either anesthesias. The correlations between the percent change of circulatory indices and the logarithm of the blood anesthetic concentrations were expressed by correlation coefficients (r): mAP, r=-0.718 (H), and -0.650 (E); HR, r=-0.329 (H), and -0.352 (E); CI, =-0.597 (H), and -0.596 (E); SVR, r=-0.161 (H), and -0.030 (E); peak bp/dt/IP, r=-0.708 (H), and -0.871 (E). Using several indices of anesthetic depth including MAC, MAC-EI and MAC-BAR, the percent change of mAP, CI and peak dp/dt/IP were calculated at the same anesthetic depth using halothane or enflurane. These results indicated that enflurane depressed these circulatory indices more than halothane. These defferences were: mAP, 14.51±1.46%; CI, 8.14±1.86%; peak dp/dt/IP, 7.38±3.95% (mean±SD). These results, indicate that the depression of circulatory indices at the same anesthetic depth could be expressed by numerical values. en-copyright= kn-copyright= en-aut-name=KosakaMakoto en-aut-sei=Kosaka en-aut-mei=Makoto kn-aut-name=小坂誠 kn-aut-sei=小坂 kn-aut-mei=誠 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部麻酔・蘇生学教室 en-keyword=血中ハロセン濃度 kn-keyword=血中ハロセン濃度 en-keyword=血中エンフルレン濃度 kn-keyword=血中エンフルレン濃度 en-keyword=循環動態 kn-keyword=循環動態 END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=5 article-no= start-page=317 end-page=321 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=201010 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prevalence and Factors Associated with Hepatitis C Virus Infection among Myanmar Blood Donors en-subtitle= kn-subtitle= en-abstract= kn-abstract=We studied the prevalence of hepatitis C virus infection among blood donors from 3 hospitals of Central Myanmar and 7 hospitals of Lower Myanmar in the Yangon area, and analyzed the factors associated with the infection. The study period was from November, 2005 to June, 2007. A pre-tested questionnaire was used to obtain information on age, ethnic group, marital status, tattooing, body piercing, history of receiving transfusions, and liver diseases in self and in sexual partners. Data on seropositivity to hepatitis C, hepatitis B and human immunodeficiency virus infections were recorded. A total of 65,240 blood donors participated in the study. Their ages ranged from 18 years to 60 years (mean±SD＝29.5±9.3). The male-to-female ratio was 6：1. The prevalence of the antibody to hepatitis C was found to be 0.95% with varying rates (0.34 to 2.03) among hospitals. Females had a slightly higher rate (1.06%) than males (0.93%) (p＝0.237). Multivariate analyses revealed the following factors to be related to HCV infection:HIV infection, odds ratio (OR)＝3.0 (p＝0.003);history of liver disease, OR＝8.9 (p＝0.001);and age 30 years and above, OR＝2.6 (p＝0.001). We discuss the varying prevalences of HCV around the world. en-copyright= kn-copyright= en-aut-name=Myo-Khin en-aut-sei=Myo-Khin en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=San-San-Oo en-aut-sei=San-San-Oo en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KhinMay Oo en-aut-sei=Khin en-aut-mei=May Oo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShimonoKunio en-aut-sei=Shimono en-aut-mei=Kunio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KoideNorio en-aut-sei=Koide en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkadaShigeru en-aut-sei=Okada en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=Department of Medical Research-Lower Myanmar affil-num=2 en-affil= kn-affil=Department of Medical Research-Lower Myanmar affil-num=3 en-affil= kn-affil=Department of Medical Research-Lower Myanmar affil-num=4 en-affil= kn-affil=Shimono Naika-Geka Clinic affil-num=5 en-affil= kn-affil=Department of General Medicine, Okayama University Hospital affil-num=6 en-affil= kn-affil=Department of General Medicine, Okayama University Hospital en-keyword=Myanmar kn-keyword=Myanmar en-keyword=hepatitis C prevalence kn-keyword=hepatitis C prevalence en-keyword=blood donors kn-keyword=blood donors en-keyword=associated factors kn-keyword=associated factors END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=4 article-no= start-page=243 end-page=248 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=201008 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-Term Management of Hepatitis C-Seropositive Subjects with AntiOxidant Biofactor (AOB?), a Fermented Food Supplement en-subtitle= kn-subtitle= en-abstract= kn-abstract=The efficacy of AntiOxidant Biofactor (AOB(R)) for the management of apparently healthy subjects with chronic hepatitis C infection was investigated.

The initial mean (SD) serum alamine aminotransferase (ALT) level was 46.3+/-35.4IU/L, and significant (p0.05, paired t-test) reductions in the mean serum ALT levels were observed at 6 months (38.6+/-21.5IU/L), 18 months (31.9+/-18.1IU/L), 2 years (31.2+/-14.6IU/L), and 3 years (28.0+/-15.9IU/L). Those presenting with high serum ALT levels (30 subjects) demonstrated significant levels (p0.05, paired t-test) of reduction in the mean serum ALT levels at 6, 12, 18, 24, and 36 months of treatment. No side effects were observed and the AOB treatment was well tolerated by all subjects. en-copyright= kn-copyright= en-aut-name=Myo-Khin en-aut-sei=Myo-Khin en-aut-mei= kn-aut-name= kn-aut-sei=

Objectives: To investigate the relationship between the plasma B-type natriuretic peptide (BNP) level and the occurrence of atrial fibrillation (AF) in nonobstructive hypertrophic cardiomyopathy (HCM) patients.
Methods: Patients (n=97) were classified into chronic AF (CAF; n=14), paroxysmal AF (PAF; n=18) and normal sinus rhythm (NSR; n=65) groups. The plasma BNP values were analyzed with logarithmic transformation.
Results: The PAF group showed significantly higher plasma BNP levels than the NSR group [mean (range; -1 SD and +1 SD); 248.3 (143.5, 429.5) vs. 78.2 (27.9, 218.8 ng/L), p<0.0001]. The CAF group also showed significantly higher plasma BNP levels than the NSR group [291.1 (161.4, 524.8 ng/L), p<0.0001]. Multivariate analysis with other clinical factors selected association of PAF as one of the factors that increased the plasma BNP level.
Conclusions: The present study indicated that plasma BNP level is clinically useful for identification of nonobstructive HCM patients who have a risk of PAF.

A patient presented with sudden hearing loss on her ?rst visit to our department. Gadolinium-DTPA-enhanced magnetic resonance imaging (MRI) of the posterior cranial fossa portrayed an intracanalicular tumour image (2?3 mm), and the pure tone average (PTA) and speech discrimination score (SDS) values were 65 dB and 60 per cent, respectively. Surgical intervention to remove the suspected tumour was scheduled by the translabyrinthine approach. Intracanalicular observations by the retrolabyrinthine approach revealed limited oedema on the inferior vestibular nerve with vascular dilation. The tumour image disappeared two years after the operation. Surgical ?ndings and the post-operative course advocate that gadolinium-DTPA-enriched MRI image of an intracanalicular lesion such as arachnoiditis might produce a false-positive result.

In this paper, the effects of fluid shear stress on morphology and elastic properties of endothelial nuclei were investigated. The morphological observation suggested that the nuclei in the cytoplasm were being vertically compressed under static conditions, whereas they were elongated and more compressed with a fluid shear stress of 2 Pa (20 dyn/cm(2)) onto the cell. The elongated nuclei remained the shape even after they were isolated from the cells. The micropipette aspiration technique on the isolated nuclei revealed that the elastic modulus of elongated nuclei, 0.62 +/- 0.15 kPa (n = 13, mean +/- SD), was significantly higher than that of control nuclei, 0.42 +/- 0.12 kPa (n = 11), suggesting that the nuclei remodeled their structure due to the shear stress. Based of these results and a transmission electron microscopy, a possibility of the nucleus as an intracellular compression-bearing organelle was proposed, which will impact interpretation of stress distribution in adherent cells.

Participants were enrolled and assigned to relaxation or control groups. The relaxation group Japanese female medical workers (n = 38, mean age = 33.5 years, SD = 9.6) participated in a lecture on stress for 1 h and had 10 min of relaxation training. The control group (n = 41, mean age = 35.0 years, SD = 8.6) participated in only the lecture. S-IgA was measured, and a self-report mood questionnaire administered before the lecture and then again after the relaxation training for the relaxation group. The control group was measured before and after the lecture. The results showed that s-IgA levels significantly increased after relaxation training in the relaxation group compared with the control group (p = 0.03). A marginally significant intervention effect was observed for mood state (p = 0.06) ; indicating that the relaxation group was more likely to reduce any fatigue and confusion than was the control group. These findings suggest that short-time relaxation training is effective in relaxing mood and causes changes in immunological function. en-copyright= kn-copyright= en-aut-name=TaniguchiToshiyo en-aut-sei=Taniguchi en-aut-mei=Toshiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HirokawaKumi en-aut-sei=Hirokawa en-aut-mei=Kumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsuchiyaMasao en-aut-sei=Tsuchiya en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawakamiNorito en-aut-sei=Kawakami en-aut-mei=Norito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University affil-num=3 en-affil= kn-affil=Okayama University affil-num=4 en-affil= kn-affil=University of Tokyo en-keyword=relaxation training kn-keyword=relaxation training en-keyword=immediate eff ects kn-keyword=immediate eff ects en-keyword=female medical co-workers kn-keyword=female medical co-workers en-keyword=salivary immunoglobulin A kn-keyword=salivary immunoglobulin A END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=4 article-no= start-page=221 end-page=227 dt-received= dt-revised= dt-accepted= dt-pub-year=2007 dt-pub=200708 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Autonomic Dysreflexia during a Bowel Program in Patients with Cervical Spinal Cord Injury. en-subtitle= kn-subtitle= en-abstract= kn-abstract=The purpose of the present study was to investigate the relationship between bowel maneuvers and autonomic dysreflexia (AD) in patients with cervical spinal cord injuries (CSCI). Fifteen consecutive, clinically stable patients with CSCI participated. We evaluated changes in blood pressure (BP), pulse rate (PR) and classic symptoms of AD before, during and after a bowel program involving the manual removal of stool in lateral recumbency. The insertion of rectal medication induced a significant increase in systolic BP, which persisted during additional digital rectal stimulation. Furthermore, the manual removal of stool induced AD, with maximal increases of systolic BP (169.1(+-)19.5 mmHg, mean(+-)SD). However, the insertion of a finger into the anus after the end of stool flow did not cause a further increase in systolic BP. Systolic BP recovered to pre-program values within 5 min after defecation. Our study demonstrated that the combined effects of rectal and/or anal sphincter distension and uninhibited rectal contraction in response to the manual removal of stool might induce AD. We recommend avoiding, if at all possible, the manual removal of stool in order to prevent AD in patients with CSCI. en-copyright= kn-copyright= en-aut-name=FurusawaKazunari en-aut-sei=Furusawa en-aut-mei=Kazunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugiyamaHiroyuki en-aut-sei=Sugiyama en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IkedaAtsushi en-aut-sei=Ikeda en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TokuhiroAkihiro en-aut-sei=Tokuhiro en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KoyoshiHiroko en-aut-sei=Koyoshi en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakahashiMasanori en-aut-sei=Takahashi en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TajimaFumihiro en-aut-sei=Tajima en-aut-mei=Fumihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=Kibikogen Rehabilitation Center for Employment Injuries affil-num=2 en-affil= kn-affil=Kibikogen Rehabilitation Center for Employment Injuries affil-num=3 en-affil= kn-affil=Kibikogen Rehabilitation Center for Employment Injuries affil-num=4 en-affil= kn-affil=Kibikogen Rehabilitation Center for Employment Injuries affil-num=5 en-affil= kn-affil=Kibikogen Rehabilitation Center for Employment Injuries affil-num=6 en-affil= kn-affil=University of Occupational and Environmental Health affil-num=7 en-affil= kn-affil=Wakayama Medical University en-keyword=spinal cord injury kn-keyword=spinal cord injury en-keyword=autonomic dysrefl exia kn-keyword=autonomic dysrefl exia en-keyword=blood pressure kn-keyword=blood pressure en-keyword=bowel program kn-keyword=bowel program END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=3 article-no= start-page=287 end-page=302 dt-received= dt-revised= dt-accepted= dt-pub-year=1970 dt-pub=197006 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Studies on nucleic acids in Rous sarcoma virus-induced mouse ascites sarcoma cells. Distribution and electron microscopy of nucleic acids in subcellular fractions and circular DNA in mitochondrial fraction en-subtitle= kn-subtitle= en-abstract= kn-abstract=

For the purpose to clarify the distribution of DNA in mouse ascites sarcoma cells (SR-C3H) induced by Rous sarcoma virus (Schmidt-Ruppin strain), quantitative assays were carried out by SCHMIDT-THANNHAUSERSCHNEIDER'S method using subcellular fractions isolated from SR-C3H cells and C3H mouse liver as a control tissue, and simultaneously electron microscopic observations were conducted with the rotary shadowed preparations of the SDS-phenol extracted nucleic acids by the protein monolayer technique. The results are briefly summarized as follows. 1. The RNA/DNA ratios in SR-C3H cells and liver cells were 2.3 and 3.7, while those in nuclear fraction of SR-C3H cells and liver cells were 0.34 and O. 56, respectively. The electron micrographs of nuclear nucleic acids revealed a DNA-RNA complex-like structure. 2. DNA and RNA contents of SR-C3H mitochondria were found to be 3.1 and 24 fl-g per mg of protein, respectiVely, which proved to be greater than those of liver mitochondria. The mean values of the contour length of circular DNA molecules in highest frequency group observed in the electron micrographs were 4.88 μ. in SR-C3H mitochondria and 5.08 μ. in mouse liver mitochondria. There could be observed circular molecules of duplicated-length in both mitochondrial DNA's and small circular molecules in SR-C3H mitochondrial DNA. 3. In the microsomal and supernatant fractions of SR-C3H cells and mouse liver cells, the ratios of DNA to RNA gave several percent by chemical analysis and this percentage was particularly high in the supernatant of SR-C3H cells. On the other hand, in the electron micrographs, the fibrous structure was significantly recovered in the supernatant nucleic acids of SR-C3H cells, but with difficulty in the other three fractions. This fibrous structure measured 1.13 μ in the mean value of the length and was considered to be DNA as it readily disappeared after the treat? ment with DNase.

The RNA extracted from Rous sarcoma virus (RSY)induced mouse ascites sarooma cells (SR?C3H, N. P.) by means of the cold SDS-phenol was examined by the electron microscopy on the specimens spread wi th or wi thout urea according to the protein mono? layer technique. The majority of RNA molecules was found in a collapsed agglomerated form, derived from matured ribosomal RNA. Using sucrose gradient, linear molecules of RNA were observed in the interspace of the agglomerated form of RNA at the region of high molecular weight of the band sedimentation. The histogram of the distribution in length of the linear molecules involved up to 6 /1 in length wi th a modal length of 2. 28 f1 and 2.0 to 2. 2 f1 in a pro. minent peak; longer molecules up to 18 f1 in length were scarcely observed. Species of the linear RNA molecules is not exactly known, although this is not mature ribosomal RNA and likely to be messenger RNA or nascent RNA molecules, some of which might associate with RSY?RNA.

The results of our study may briefly be summarized as follows: 1) The irradiation with microrays (20∼30 watts) similar as 2,000 R and 5,000 R Gamma radiation did not substantially affect the activity of fibrinolysin (SK+SD). 2) By the irradiation method so far mentioned it has been demonstrated that the fibrinolytic activity of anticoagulant of the SK+SD preparation is preserved in all the clotting systems which we used. 3) Our findings indicate that it is possible to irradiate patients for therapeutical purpose with Radarmed (electromagneticrays) provided that there is produced some enhancing influence of the same blood clotting factors or systems. Together with earlier works in this field it appears that this method of the microirradiation could provide us with an important evidence on which we can base our further in vitro and in vivo radiohematologic studies; investigations with various preparations, types of radiation that are still underway9∼16.

We investigated the restriction of the host range to infectivity of MSV by helper leukemia virus in vivo. When newborn SD-rats were inoculated intracerebrally, subcutaneously, intraperitoneally or intramuscularly with xenotropic pseudotype Kirsten MSV, Ki-MSV(BV2), either brain tumors or myogenic sarcomas were induced, depending upon the route of inoculation. However, no tumors developed in SW-Icr mice inoculated with Ki-MSV(BV2) either intracerebrally or intramuscularly at birth. Ecotropic Ki-MSV(Ki-MuLV) induced myogenic sarcomas in mice when inoculated intramuscularly and also induced brain tumors and myogenic sarcomas in rats when inoculated intracerebrally and intramuscularly, respectively. Thus, the host range of pseudotype MSV appeared to depend on a helper leukemia virus.

We studied total nitric oxide (nitrite + nitrate) (NO) levels in cerebrospinal fluid (CSF) of chronic spinal diseases in nonsmokers (133 patients: 76 men and 57 women; mean age, 63 years; range, 15-92 years) by the Griess method to clarify the role of NO in different spinal diseases. The extent of compression in terms of numbers of disc level at the compressed spinal nerve and neurological evaluation were also assessed according to the Japanese Orthopaedic Association scores. The spinal diseases included cervical myelopathy and radiculopathy (cervical disease group), ossification of yellow ligament (thoracic disease group), and lumbar disc herniation, lumbar canal stenosis and lumbar spondylolisthesis (lumbar disease group). NO levels in the spinal disease groups (4.98+/-2.28 micromol/l: mean +/- SD) were significantly higher than that in the control group (2.53+/-0.94 micromol/l). An inverse correlation was detected between the elevated levels of NO and the grade of clinical symptoms in the cervical disorders. The number of disc level at the compressed spinal nerve was positively correlated with elevated NO levels in CSF in the cervical and lumbar disorder groups. These results indicate that nerve compression may elevate NO levels in CSF, and that NO concentration in the CSF might be a useful marker of damage to nervous system in spinal disorders.

The metabolism of L-cysteine in guinea pig liver was studied. Guinea pig liver contained 0.45 +/- 0.05 (mean +/- SD) mumol of cysteine, 0.180 +/- 0.080 mumol of 3-mercaptolactate-cysteine disulfide [S-(2-hydroxy-2-carboxyethylthio)cysteine, HCETC], and 8.082 +/- 0.516 mumol of reduced glutathione per g of fresh tissue. The taurine content was 0.912 +/- 0.158 mumol per g of fresh liver. Cysteine dioxygenase (EC 1.13.11.20) activity was several-fold lower than cysteine aminotransferase (EC 2.6.1.3) activity. Lactate dehydrogenase (EC 1.1.1.27) activity was about 10-fold higher than 3-mercaptopyruvate sulfurtransferase (EC 2.8.1.2) activity. These results indicate that the oxidative metabolism of L-cysteine in the guinea pig liver is not as active as in the rat liver and that L-cysteine, at least in part, is metabolized via the transaminative pathway, in which 3-mercaptopyruvate is partly reduced to 3-mercaptolactate and is utilized to form HCETC.

In an attempt to evaluate high density lipoprotein (HDL) subfraction levels in liver diseases, HDL was separated by a precipitation method with dextran sulfate-Mg2+ from sera of 289 healthy adults and 50 patients with liver diseases. The HDL was subdivided into HDL2e and HDL3e by Utermann's polyacrylamide gel electrophoresis with lauric acid. Ultracentrifugally separated HDL2 and HDL3 roughly corresponded to HDL2e and HDL3e, respectively. Male and female groups had different distributions of HDL2e/HDL3e ratios. Among healthy males, 121 cases had ratios less than 1.0 (mean +/- SD = 0.72 +/- 0.39, n = 150), while among healthy females, the ratios were generally larger than those of males and varied widely from 0.2 to 6.6 (mean +/- SD = 1.77 +/- 1.05, n = 139). Low levels of HDL-cholesterol were found in patients with liver diseases, except those with mild alcoholic liver injury and intrahepatic cholestasis. Apparent decreases in HDL3e, but not in HDL2e, were found in all cases with liver diseases investigated, even in those who did not show decreases in the total HDL level, when male and female patients were analyzed separately. The analysis of HDL subfractions by the present method is simple and useful for the study on altered lipid metabolism in liver diseases.

125I-labeled insulin binding to peripheral human erythrocytes was studied in patients with chronic liver disease. The maximum specific 125I-labeled insulin binding was 12.10 +/- 1.13 %/4 x 10(9) cells (mean +/- SD, n = 10) in normal subjects, and significantly higher in cirrhotic patients (15.32 +/- 1.73 %, n = 11, P less than 0.01) but not in patients with acute and chronic hepatitis (11.44 +/- 2.10 %, n = 3 and 13.2 +/- 1.87 %, n = 7 respectively). The complication of diabetes mellitus significantly increased (P less than 0.05) the maximum insulin binding in chronic hepatitis. Scatchard analysis and average affinity analysis of the binding data suggest that increased insulin binding in cirrhotic patients is due to an increase in the number of insulin binding sites per erythrocytes. The complication of diabetes in chronic liver diseases results in an increase in affinity of insulin binding sites.

Insulin and human erythrocyte cell membrane interactions were studied with respect to binding and dissociation. The per cent of specific binding of 125I-labeled insulin to erythrocytes was directly proportional to the cell concentration. The optimum pH for binding was 8.1. The initial binding rate was directly proportional to, and the steady state insulin binding was reversely proportional to, the incubation temperature. The per cent of specific binding of 125I-labeled insulin was 12.10 +/- 1.13 per cent (mean +/- SD)/4 X 10(9) cells (n = 10) at 0.8 ng/ml insulin. Native insulin competed with 125I-labeled insulin for binding and showed almost complete inhibition at 10(4) ng/ml. The Scatchard plots were upward concave. Maximum binding capacity was 230 binding sites per cell. The average affinity constant decreased as the per cent of fractional occupancy increased. Affinity constants for the empty and filled sites were 1.49 and 0.16 X 10(8) M-1 respectively. Bound insulin was displaced by native insulin. The dissociation rate by "dilution + native insulin" was higher than that by "dilution only". The dissociation rate was accelerated even by the physiological concentration of insulin and maximum at 100 ng/ml. It is concluded that human erythrocytes have insulin binding sites which are indistinguishable from insulin receptors on the target tissues for insulin.

Serum specimens from 12 patients with type A hepatitis were analyzed for immunoglobulin M-type antibody to hepatitis A virus (IgM anti-HA). A recently developed solid-phase radioimmunoassay kit for IgM anti-HA (HAVAB-M, Abbott Laboratories) and a competitive binding radioimmunoassay kit (HAVAB, Abbott Laboratories) with or without 2-mercaptoethanol treatment, as modified by Yano et al. (Acta Hepatol. Jpn. 21, 704-712, 1980) were used to obtain an M-index. All specimens obtained within 60 days of the onset of illness and specimens from 2 of 4 patients later than 60 days after the onset were positive with the HAVAB-M test. This test gave negative results to sera which were positive for anti-HA by a standard HAVAB test in the following: 3 patients with type B hepatitis; 5 with non-A, non-B hepatitis; 11 healthy adults; and 10 sera strongly positive for rheumatoid factor. The M-index for type A hepatitis in sera within 30 days of the onset (mean value of the M-index, m, = 1.52; standard deviation, SD, = 0.25) was significantly higher than that for non-A hepatitis (m = 1.05; SD = 0.15) and for healthy adults (m = 1.02; SD = 0.10). The simplicity and usefulness of the HAVAB-M test in diagnosis of acute type A hepatitis over those measuring the M-index by HAVAB tests were shown by direct comparison of the results.

In order to get precise information about the movement of plasma membrane proteins in cap formation, cyto- and bio-chemical analyses were made of the plasma membranes from non-capped areas of Ehrlich ascites tumor cells (EATCs) exposed to concanavalin A (Con A). Blebs formed by treatment with cytochalasin B (CB) of the non-capped areas of cells having a cap were isolated and used as the plasma membranes from non-capped areas (ConA-CB-bleb fraction). This bleb fraction was compared with a bleb fraction prepared from cells without ConA-treatment (CB-bleb fraction). Cytochemical analysis of ConA-CB-bleb fraction revealed a decreased in conA binding sites (ConA-BS) compared to the CB-bleb fraction. SDS polyacrylamide slab gel electrophoresis also revealed a decrease in the major components of ConA-BS of the ConA-CB-bleb fraction. The minor components of ConA-BS showed no distinct quantitative difference between the ConA-CB-bleb and CB-bleb fractions. NA+ K+-adenosine triphosphatase (ATPase), 5' nucleotidase (5'ND) and gamma-glutamyl transpeptidase (gamma-GTP) did not show any decrease in activity in the ConA-CB-bleb fraction, but the activity of D+-stimulated phosphatase (K-Pase) was decreased. The findings indicate that there are two types of plasma membrane glycoproteins in EATCs; one includes those participating in cap formation due to ConA, e.g. the major components of ConA-BS and K-Pase, and the other, those not participating in such cap formation, e.g. some minor components of ConA-BS, ATPase, 5'ND and gamma-GTP, which keep their places without moving.

I. Binding of endotoxin to platelets. en-subtitle= kn-subtitle= en-abstract= kn-abstract=

Binding of bacterial endotoxin to platelets, erythrocytes, lymphocytes and granulocytes was examined by using diffusion dialysis. Platelets, erythrocytes, lymphocytes and granulocytes were fractionated from normal human blood and the binding of endotoxin (LPS: Lipopolysaccharide of E. coli) to each cell fraction was measured at 4 degrees C and the binding efficiency was expressed as a binding index (%d4degreesC +/- SD). The binding index for each cell fraction was as follows; 10.2 +/- 1.6 for platelets, 1.0 +/- 0.9 for erythrocytes, 4.3 +/- 1.6 for lymphocytes and 10.0 +/- 1.5 for granulocytes (n = 11) respectively. Since a platelet possesses a small cell surface area compared with other cells, it was clear that the endotoxin bound preferentially to platelets in vitro. The binding mechanism to the platelet cell surface was suggested to be direct binding of endotoxin to the receptor on platelet cell membrane rather than through an immunologically activated mechanism.

Euchromatin specimen prepared by the usual method formed large clumps and had various shapes under electron microscopy. A method of separation of the euchromatin specimen into chromatin fractions having relatively homogeneous form was examined and partial characterization of these fractions was carried out. The heavy euchromatin fraction was a large network of thin fibrils (about 100 A in diameter) and various thick fibers. The intermediate euchromatin fraction consisted of relatively homogeneous networks of thick knobby fibers (about 250 A in diameter). The light euchromatin fraction had metworks of thick fibers. These chromatin fractions were quantitatively prepared from sonicated nuclei of mouse ascites sarcoma cells. Twenty-one or twenty-two bands of non-histone proteins besides histones were detected in these chromatin fractions by SDS-polyacrylamide gel electrophoresis. There were significant differences in the electrophoretic patterns of non-histone proteins among these chromatin fractions.

Levels of erythrocyte superoxide dismutase (SOD) activitiy in a sample of Japanese people were determined. Blood samples were taken from new-born infants, preschool children, young and old people who had no apparent diseases and also from three anemic patients. Erythrocyte SOD activities in different age groups had a nearly normal distribution. Females had slightly lower activities than males, although the difference was statistically insignificant. The distributions of SOD activities were 12.6 +/- 2.7 (m +/- SD) unit/mg Hb in young people and 11.4 +/- 3.0 in old people, indicating that erythrocyte SOD activity falls with aging. Because of low concentration of hemoglobin, SOD activities of old people expressed as unit/ml blood were much lower than in young people. Three anemic patients had slightly lower SOD activity.

Natural killer (NK) cell activity, lymphokine activated killer (LAK) activity and Epstein-Barr virus specific cytotoxic T lymphocyte (EBV-CTL) activity were examined in 10 children with chronic active EB-virus infection and an adult with persistently positive early antigen-antibody to EB-virus. NK cell activity against erythroleukemia cell line K-562 was significantly (p less than 0.005) lower in the patients (22.3 +/- 8.5%, mean +/- SD) than in normal controls (40.4 +/- 15.9%). Spontaneous cytotoxicity against an EB-virus transformed autologous lymphoblastoid cell line was 15.0 +/- 7.6% in the patients, and was comparable to spontaneous cytotoxicity activity in normal controls (11.7 +/- 4.3%). LAK activity against Raji cells was significantly (p less than 0.02) lower in the patients (14.6 +/- 11.4%) than in normal controls (29.2 +/- 15.9%). EBV-CTL activity against an EB-virus transformed autologous lymphoblastoid cell line was significantly (p less than 0.005) lower in the patients (11.8 +/- 5.5%) than in seropositive normal controls (33.7 +/- 14.7%). No regression of the lymphoblastoid cell line was observed when EBV-CTL activity of the patients was tested by regression assay. It is conceivable that defects in both EB-virus specific and nonspecific killer cell activities play important roles in the pathogenetic abnormalities which allow EB-virus infection to progress to a chronic active state.

The development of useful therapy for intraabdominal carcinomatosis originating from gastrointestinal cancer is an important theme in cancer therapy. We developed recently an experimental model of intraabdominal carcinomatosis in nude mice by intraperitoneal transplantation of human colon cancer cells (RPMI 4788). Using this model, we investigated the antitumor effects of recombinant human interferon (rIFN)-beta and rIFN-gamma administered singly or in combination. Treatment was initiated 2 days after CD-1 nude mice were inoculated intraperitoneally with 5 X 10(6) RPMI 4788 cells. Intraperitoneal administration for 10 consecutive days of either rIFN-beta (2.5 X 10(5) IU/mouse/day) or rIFN-gamma (2.5 X 10(5) JRU/mouse/day) resulted in a significant prolongation of survival compared with the saline control group [survival in the control: 41.8 +/- 5.6 days (mean +/- SD)]. Combined administration of rIFN-beta and rIFN-gamma for 10 days yielded a marked synergistic effect on the prolongation of survival (114.0 +/- 8.2 days). However, combined administration of rIFN-beta and rIFN-gamma in a single dose equal to the total dose given fractionally over 10 days did not yield a synergistic effect. These results suggest that daily administration of rIFN-beta and rIFN-gamma combined may provide a highly potent antitumor effect against human peritoneal carcinomatosis.

The aim of this study is to clarify visual symptoms and compliance with spectacle wear in children kusing progressive addition lenses (PALs). Ninety-two children, participating in a randomized, doublemasked, crossover trial to determine whether PALs reduce myopia progression (mean+/-SD age: 11.0+/-1.6 years; refractive errors: 3.11+/-1.34 D), wore PALs (1.50 D near addition) or single vision lenses (SVLs) for 18 months, alternately. A questionnaire survey was performed 6 and 12 months after the beginning of the use of the lenses (6-month survey), and the results were compared between PAL- and SVL-wearing periods. In the PAL-wearing period, the children reported difficulty in adapting to newly provided spectacles (36%), disturbances in distance vision (22%), vertigo in the lateral gaze (11%), and difficulty in ascending and descending stairs (9%). However, the frequency of these symptoms was not significantly different from that reported in the SVL-wearing period. There was no difference in compliance with spectacle wear between the PAL- and SVL-wearing periods, and 98% of the children wearing PALs reported excellent compliance. The results of this study indicate that, compared with SVLs, the PALs provide a similar level of comfort and compliance with spectacle wear for myopic children.

An anti-membrane antibody was present in the sera of systemic lupus erythematosus patients in immunoelectrosyneresis with sodium dodecyl sulfate (SDS) solubilized erythrocyte membrane as antigen. The SDS bound to protein was detected by chromatography at 10(-3)M concentration under U.V. light, at 10(-5)M concentration by the distilled water spray method and at 10(-6)M concentration by using rosaniline hydrochloride colorimetry. SDS was removed from the membrane protein at a concentration of 10(-3)M by the first gel filtration of Sephadex G-25 column and at a concentration of 10(-6)M by rechromatography of the same column. More than 99% of SDS in the solubilized erythrocyte membrane was removed by gel filtration. The antigenicity was still positive in the refiltrated fractions of systemic lupus erythematosus patients. Therefore, all precipitates in the gels were antigen-antibody aggregates.

Further purification and characterization are reported on rat cytosol cornin (RLCC), an antimitotic substance. Fraction I (purified RLCC) was purified more than 10-fold from crude RLCC with Sephadex G-50 column chromatography and showed a remarkable inhibitory effect on division of inseminated sea urchin eggs and mouse fibroblast cells. Fraction I was observed as one spot, and the molecular weight was estimated to be about 25,000 by thin layer gel filtration. Fraction I contained protein (92%) and RNA (8%), but the antimitotic activity was scarcely affected by treatment by pancreatic RNase. The protein of Fraction I was separated into two bands by SDS-polyacrylamide gel electrophoresis, and the molecular weight was estimated as 10,000 and 15,000, respectively. The 50% inhibition dose of Fraction I on the first division of inseminated sea urchin eggs and on proliferation of mouse L cells was about 2.5 X 10(-5) g/ml and 5 X 10(-4) g/ml, respectively. The yield of fraction I was about 35 mg from 100 g rat liver.

A study was conducted to examine the relationship of testicular atrophy to bone metabolism in male leprosy patients. The study consisted of 31 leprosy patients (mean age: 62.0 years) and 31 healthy control men (mean age: 60.0 years). Measurements were made of their serum levels of free testosterone (FT), estradiol (E2), luteinizing hormone (LH) and 25-hydroxyvitamin D (25 OHD). Bone mineral density (BMD) was measured at radial sites and the lumbar vertebral bodies (L2-L4) by dual-energy X-ray absorptiometry using a Hologic QDR-2000 densitometer. FT and E2 levels were significantly lower and LH levels higher in leprosy patients than in controls. This represents a primary hypogonadal pattern. A value of 7.20pg/ml of FT (= Mean -1 SD of control) was used as a cut off value, and the subjects were subdivided into a hypogonadal group (HG) and a non hypogonadal group (non-HG). When the subjects were compared for differences in age, age at onset of disease, duration of disease, body mass index and BMD, only the duration of disease and BMD were significantly different between the two groups. Furthermore, BMD of the forearm significantly correlated with FT levels (r = 0.689, P < 0.0001). Low BMD may be due to orchitis and testicular atrophy.

A novel endonuclease of 55-kDa was found in rat liver mitochondria by a zymographic assay, in addition to the 29 kDa enzyme that is well-known as endonuclease G (Endo G). Subcellular localization of these enzymes in rat liver cells was examined by biochemical fractionation. Endo G was located in both nuclei and mitochondria as has been previously reported, while the 55-kDa enzyme was only detected in the mitochondrial fraction. The levels of the endonucleases in the mitochondria varied greatly among the rat organs, and the activity in the heart was about 30 times higher than that in the liver. The 55-kDa enzyme and Endo G were extracted from bovine heart mitochondria with 0.4 M NaCl. During purification the 55-kDa enzyme and Endo G were copurified because of their similar chromatographic behavior, so they were separated by gel filtration or electrophoresis in the presence of SDS and the proteins were then renatured. The nucleolytic properties of the 55-kDa enzyme resembled those of Endo G and other known mitochondrial nucleases. The enzyme degraded single-stranded DNA more rapidly than duplex DNA at a weak alkaline pH, requiring Mg2+ or Mn2+ but not Ca2+ or Zn2+. Nicks generated by the enzyme had 5′-P and 3′-OH ends. The 55-kDa enzyme, like Endo G, displayed an unusually strong preference to nick within a (dG)n ? (dC)n tract.

Using a transcranial Doppler blood flowmeter, the blood flow velocity (BFV) ratio of the middle cerebral artery (MCA) to the basilar artery (BA) was investigated in 12 patients with severe motor and intellectual disability syndrome. The BFV of the MCA was also investigated in 58 handicapped children, classified according to the severity of their motor and intellectual disability. The ratio of the MCA to the BA was lower by 2 SD from the mean of our previously reported standard value in 8 out of the 12 cases with severe motor and intellectual disability syndrome, suggesting a more profound decrease in the level of brain activity in the MCA area than that of the BA area. The BFV of the MCA mainly decreased in cases belonging to the category of the most severe motor disability (bed-ridden). Hence, it is suggested that motor disability is the main factor related to the decrease in the BFV of the MCA.

Erythrocyte catalase in normal and Japanese type acatalasemia hemolysates was separated by chromatofocusing into several fractions in the pH range of 6.1 to 5.7. Normal hemolysate gave a major peak of catalase activity with a pH of 6.1 to 5.5, while acatalasemia hemolysate gave several small peaks in this pH range and a main peak with a pH of 6.6 to 6.2. The main protein band in catalase active fractions separated from normal erythrocytes had a molecular weight of 60,000 by SDS polyacrylamide gel electrophoresis. A similar faint protein band having a molecular weight of 60,000 was also found in acatalasemia hemolysate in addition to a fairly intense band with a molecular weight of about 30,000. Catalase active fractions from normal erythrocytes reacted with antihuman erythrocyte catalase rabbit serum by double immunodiffusion.

For the detection and characterization of circulating immune complexes (CIC) in various liver diseases, a Clq binding test was used. Though the CIC level was almost normal in HB surface antigen (HBsAg) positive asymptomatic carriers, the level increased in patients with liver diseases. During acute exacerbation of chronic viral hepatitis, the CIC level reached peaks 1 to 3 weeks before and after the hepatic cell necrosis. Study of the sedimentation rates of CIC in various liver diseases showed CIC in the 19s-22s region and in the 7s-19s region. In acid buffer, CIC was dissociated into 5 to 6 components by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). In one case of HBsAg positive severe chronic aggressive hepatitis, CIC was composed of HBsAg, IgG and another three or four undetermined components. During acute exacerbation of chronic hepatitis, minor changes of these dissociation patterns of CIC were observed.

A shortage of donor organs in clinical transplantation prompted us to study whether resuscitated dead hearts could be utilized for successful orthotopic heart transplantation. After 60 min of hypoxic cardiac arrest, one group of canine hearts was resuscitated (Res group, n = 6). The other group was harvested directly (Non-Res group, n = 6). In the Res group, cardiopulmonary bypass was utilized for resuscitation at 37 degrees C and the animals were then core-cooled to 15 degrees C. The hearts then were preserved in University of Wisconsin solution and orthotopically transplanted. Stable prostacyclin analogue (OP2507) and verapamil, a calcium antagonist, were added to the cardioplegia, and substrate-enriched warm blood cardioplegia and a hydroxy radical scavenger (EPC) were administered at the time of reperfusion of the transplanted heart. All animals in each group were successfully weaned from cardiopulmonary bypass with dopamine (5 micrograms/kg/min). Cardiac function without dopamine was better preserved in the Res group than the Non-Res group (Emax: 130.6 +/- 41.5% vs. 47.1 +/- 24.7%; mean +/- SD, as percent of postbrain death values, P < 0.01 by unpaired t-test). Cadaver hearts 60 min after anoxic arrest can be successfully re-animated and orthotopically engrafted. In addition, the core-cooling technique is useful. We believe this study serves as the key step in the clinical application of dead hearts to successful cardiac transplantation.

Peptides and proteins in the extracellular space in the central nervous system were investigated in vivo using an intracerebral microdialysis probe. The molecular cut-off of the hollow fiber which was used for the probe was approximately 100 kDa. We examined recovery rates of several compounds in vitro. The recovery rates of proteins and peptides were between 7-28%, with the exceptions of substance P and insulin-like growth factor I. The recovery rates of monoamines and their metabolites were 22-40%. In in vivo studies, two major proteins with apparent molecular weights of 62 kDa and 12 kDa, and several minor proteins (28 kDa, 43 kDa, 52 kDa and 70 kDa) were detected by SDS-polyacrylamide gel electrophoresis in the dialysate from a probe implanted in the striatum of anesthetized rats. These results suggest that the newly developed, intracerebral microdialysis probe might be useful for investigating the dynamic changes of peptides and proteins in the central nervous system.

The excretion of 3-mercaptolactate-cysteine mixed disulfide [S-(2-hydroxy-2-carboxyethylthio)-L-cysteine, HCETC], sulfate and taurine in the urine of normal adults was investigated before and after oral administration of L-cysteine and related sulfur-containing amino acids. Before the loading of amino acids, the excretion (mean +/- SD) per kg of body weight per day of HCETC, free sulfate and taurine was 0.096 +/- 0.042, 305.7 +/- 66.1 and 31.9 +/- 8.7 mumols, respectively. After the loading of L-cysteine (800 mumols/kg of body weight), the average excretion in the 24-h urine of HCETC increased 2-fold and that of taurine increased 1.6-fold. The average excretion of free sulfate after the L-cysteine loading was 989.4 +/- 145.1 and 388.8 +/- 51.6 mumols/kg per day in the first and second 24-h urine, respectively, indicating that the sulfur corresponding to 85% of the L-cysteine loaded was excreted as free sulfate in 24 h. Administration of L-cystine (400 mumols/kg) resulted in similar results. The increase in HCETC after L-cysteine or L-cystine administration indicates that L-cysteine is metabolized in part through the transamination pathway (3-mercaptopyruvate pathway) and that an equilibrium exists between the intake and excretion of sulfur in humans.

A persistent problem in orthotopic liver transplantation is primary nonfunction (PNF) of the hepatic allograft. In an attempt to reduce the incidence of graft failure, the feasibility of pretransplant assessment of graft viability was investigated by 31P nuclear magnetic resonance (NMR) spectroscopy. The level of adenosine triphosphate (ATP) was measured as an indicator of liver function by 31P NMR spectroscopy after a 30 min normothermic reperfusion following cold-storage in University of Wisconsin (UW) solution. The mean +/- SD beta-ATP/Pi ratio after preservation for 0, 12, 24 or 48 h was 1.40 +/- 0.34, 0.85 +/- 0.27, 0.64 +/- 0.14 and 0.38 +/- 0.09, respectively. Significance was observed between 12h and 24h and between 12h and 48h of preservation. These results correlated well with the morphological changes in endothelial cells and sinusoidal lining cells examined by transmission electron microscopy. It is suggested strongly that microcirculatory disturbances due to endothelial cell injury impairs the recovery of ATP levels after reperfusion, and that ATP determination by 31P NMR spectroscopy, as a non-invasive modality, may help in the prediction of PNF after liver transplantation.

Monoclonal antibodies were raised against urine proteins from diabetic patients. An antibody, YO-2, stained three protein bands with apparent molecular weights of 66, 49, and 36 kDa. These bands were not reactive with an anti-human albumin antibody. The urine levels of YO-2-reactive antigen in the normal control were 0.97 +/- 0.37 U/g-Cr (units per gram of urine creatinine) (mean +/- SD). Those of the normo-, micro-, and macroalbuminuric diabetic patients, respectively, were 1.38 +/- 1.36, 2.87 +/- 2.07, and 3.92 +/- 3.33 U/g-Cr. They were significantly higher in the micro- and macroalbuminuric patients. The urine levels of YO-2-reactive antigen had no significant correlation with the urine albumin levels and hemoglobin A1c. We concluded that; a) monoclonal antibody YO-2 recognized a non-albumin urine antigen increasingly excreted in diabetic patients with nephropathy, b) recent glycemic control of diabetes would not significantly affect the urinary excretion rate of YO-2-reactive antigen, and c) the excretion rate and probably the mechanism of YO-2-reactive protein differed from those of albumin. The urine levels of YO-2-reactive antigen could be a clinical marker of diabetic nephropathy.

The reduced hepatic blood flow calculated from hepatic scintigram with 198Au colloid was elucidated as the primary responsible factor for postoperative hepatic insufficiency. However 198Au colloid is no longer in use because of the high levels of radiation. Although 99mTc-phytate behaves similarly to 198Au on imaging, there were discrepancies between the hepatic blood flow index (KL) value and the severity of cirrhosis determined by laboratory data or by histology. In the measurement of hepatic blood flow using a radioactive colloid, factors like organ distribution, stability and uniformity of the colloid particles influence the values. In the present study, a 111In colloid was prepared and administered to rats to investigate the usefulness: as much as 95.4 (0.8) [Mean (+/- SD)]% of the colloid accumulated in the liver at pH 6.8. The distribution of particle diameter was within a relatively narrow range with the peak at 0.2 to 0.4 microns. Moreover, the KL values were not affected by condition of the reticuloendothelial system. The values showed a significant correlation with the measurements of the hepatic tissue blood flow obtained by the hydrogen gas clearance method (gamma = 0.83, P < 0.001). Thus, the 111In colloid can be clinically used as a substitute for 198Au colloid in the preoperative examination for estimation of the limit of resection.

Fas antigen (ag) is a cell surface protein known to trigger apoptosis in a variety of cells upon specific antibody binding. On the other hand, Bcl-2 protein, an oncogene product located at the mitochondrial inner surface, prolongs cell survival by blocking apoptosis. In this study we examined the expression of Fas ag and bcl-2 protein in 17 cases of hepatocellular carcinoma (HCC) to determine their role on HCC. By flow cytometric analysis, mean (SD) value of the expression of Fas ag on hepatocytes derived from normal liver, diseased liver (chronic hepatitis or liver cirrhosis) and HCC was 5.8 (4.7)%, 10.3 (6.9)%, and 24.0 (18.2)%, respectively. Fas ag expression on hepatoma cells was significantly greater than normal and diseased liver cells. The expression of Bcl-2 protein in normal liver, diseased liver and HCC was 4.3 (8.5)%, 0.8 (2.5)% and 2.1 (3.4)%, respectively, and the difference was not significant. These results suggest that induction of apoptosis may be a possible therapy against HCC.

The fungi cultivated by APC or MSLC secreted a greater number of different proteins/enzymes in larger quantities compared with fungi cultivated by SFC, particularly when DPY medium was used. In particular, the amounts of protease secreted by fungi cultivated via MSLC or APC were much greater compared with SFC. When mCD medium was used, α-amylase activity was barely detectable in all cultures while the activity was detected in MSLC and APC in a quantity that was several times higher than that in SFC using DPY medium. SDS-PAGE analysis and N-terminal amino acid sequences confirmed 6 proteins in the culture supernatants when DPY medium was used. Among these proteins oryzin (an alkaline protease) and α-amylase were detected at much higher levels in APC and MSLC compared with SFC, which was consistent with the measured activity of the secreted enzymes. However, when mCD medium was used, only oryzin was detected in significant amounts in MSLC and APC. Microarray analyses of the fungi cultivated by SFC, APC or MSLC using either mCD or DPY media indicated that the gene transcriptional profile of the MSLC sample was similar to that of the APC sample but different from that of the SFC sample. When mCD medium was used, most of the genes that were up-regulated 10-folds or greater in the MSLC sample relative to the SFC sample were unknown or predicted proteins. Transcription of the oryzin gene was only slightly up-regulated in the MSLC sample while transcription of the α-amylase gene was slightly down-regulated. On the other hand, when DPY medium was used, many known genes including the oryzin gene were up-regulated in the MSLC sample versus the SFC sample. en-copyright= kn-copyright= en-aut-name=ImanakaHiroyuki en-aut-sei=Imanaka en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaSoukichi en-aut-sei=Tanaka en-aut-mei=Soukichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FengBin en-aut-sei=Feng en-aut-mei=Bin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ImamuraKoreyoshi en-aut-sei=Imamura en-aut-mei=Koreyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanishiKazuhiro en-aut-sei=Nakanishi en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University affil-num=3 en-affil= kn-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University affil-num=4 en-affil= kn-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University affil-num=5 en-affil= kn-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=4-6 article-no= start-page=331 end-page=339 dt-received= dt-revised= dt-accepted= dt-pub-year=1963 dt-pub=19630630 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Study on Weakening of Resistance of Isoniazid-Resistant Tubercle Bacilli, Catalase-Activity and Virulence Part U Study on Weakening of INH Resistance under the Influence of Sulfa Drugs kn-title=INH耐性結核菌の耐性低下ならびにcatalase活性と毒力に関する研究 第2編 サルフア剤影響下のINH耐性低下に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=In order to make clear the mechanism of how the INH　resistance weakens under the influence of sulfa drugs, the author conducted experiments by using the method of mixed population and also tested the susceptibility of INH resistant bacilli and INH receptive bacilli to sulfa drugs and their gaining of resistance against sulfa drgus. By such experiments, the author obtained the following　results. 1. In the case of studying the clone of a perfect INH resistant strain for generations cultured in a SI-added culture medium, the author observed no weakening of the resistance. 2. Rapid weakening of INH resistance was found in the bacilli cultured in a SI-added medium for generations by use of the method of mixed population.　Assuming that this phenomenon of weakening might be attributable to the difference between the susceptibility of INH resistant bacilli to SI and that of INH receptive bacilli to SI, the author further examined but was unable to find any bacterioseptic action in either bacilli by adding 500γ of SI. As regards bacteriostatic action, no difference was observed in the case of small inoculation of bacilli. In the case of massive inoculation of bacilli difference of some measure appeared. The results of the experiments seem to indicate that, although there is no difference in the susceptibility itself between INH　resistant bacilli and INH receptive bacilli to SI, SI had delicate effects in delaying the growth of INH resistant bacilli. 3. The author studied the bacteriostatic action of long acting sulfa drugs such SD, SIM, SP and SMP and found that the action of SD and SIM was most violent,　about twice as much as that of SI. The bacteriostatic　action of SP was a little milder than that of SD and SIM and that of SMP most mild. As regards the bacteriostatic action of long acting sulfa drugs such as the ones quoted in the above on INH resistant bacilli and INH receptive bacilli, no significant difference could be found. 4. No difference was observed in the process of gaining resistance against SI between INH resistant bacilli and receptive bacilli. The resistance of neither bacilli　increased beyond 125γ. en-copyright= kn-copyright= en-aut-name=NakataniAkira en-aut-sei=Nakatani en-aut-mei=Akira kn-aut-name=中谷照 kn-aut-sei=中谷 kn-aut-mei=照 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部平木内科教室 END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=1-3 article-no= start-page=201 end-page=211 dt-received= dt-revised= dt-accepted= dt-pub-year=1963 dt-pub=19630330 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Cytochemical Study on Ascites Tumor Part 3.

And the changes of the DPN diaphorase, TPN diaphorase, succinic dehydrogenase (SD) and α-glycero-phosphate dehydrogenase (αGD) of the ascites tumor cells were cytochemically examined in the smear method and suspension method. 1) In general, moderate morphological changes of the tumor cells by these anti-tumor agents were observed, and the changes of the stainability of the oxidative enzymes were often observed. 2) After nitromin administration. no change of the stainability of the DPN diaphorase and TPN diaphorase in the smear method and slight increase of their stainability in the suspension method were observed. The stainabilities of the SD and α-GD were decreased in lesser degree in both methods. 3) After colchicine administration, no change of the stainability of the DPN diaphorase and TPN diaphorase in the smear method was observed, but their stainability of all tumor cells showed a tendency down to keep same intensity. A slight decrease of the stainability of the SD and α-GD was observed in the smear method, while their stainabilities were slightly increased in the suspension method. 4) After sarkomycin administration, stainabilities of all four enzymes were decreased in certain degree in the smear method, but the DPN diaphorase and TPN diaphorase staining intensity were remarkably decreased in the suspention method and their stainabilities of all cells showed a tendency down to keep same intensity. The SD and α-GD staining intensity were also decreased slightly in the suspension method. 5) After the administration of mitomycin C, changes of the staining intensity of the DPN diaphorase and TPN diaphorase were scarcely observed in both methods. The staining intensity of the cells in the end stage of the interphase showed to be decreased in lesser degree. Stainabilities of the SD and α-GD were slightly decreased in the smear method, while their stainabilities were slightly increased in the suspension method. 6) It might be assumed that the decrease of the stainability reacted with the anti-tumor agents in the smear method specimen showed decrease or destruction of the oxidative enzymes and that the change of stainability reacted in the suspension method specimen showed change of the activity of the enzymes. en-copyright= kn-copyright= en-aut-name=KawashimaTakao en-aut-sei=Kawashima en-aut-mei=Takao kn-aut-name=河島隆男 kn-aut-sei=河島 kn-aut-mei=隆男 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第1外科教室 END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=4-7 article-no= start-page=463 end-page=476 dt-received= dt-revised= dt-accepted= dt-pub-year=1962 dt-pub=19620330 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Cytochemical Study on Ascites Tumor. Part I. Activity of Four Oxydative Enzymes in Ehrlich Ascites Tumor Cells kn-title=腹水腫瘍の細胞化学的研究 第1編 脱水素酵素系の細胞化学的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Using the Ehrlich ascites tumor cells, the activities of the diphosphopyridine nucleotide diaphorase (DPNase), triphosphopyridine nucleotide diaphorase (TPNase), succinic dehydrogenase (SD) and α-gylcerophosphate dehydrogenase (α-GD) were cytochemically examined, and all of the cytochemical specimens were observed with the phase contrast microscope and formazanhaematoxylin counter staining. Several variations of their activities being caused by the differences of the cytochemical methods were also studied. The results were summarized as follows. 1. In the smear method, in which the ascites is smeared and dried on the object glass, thereafter reacted with the modified Wattenberg's reagents, all cells reveal relatively intense reaction but the differences of the staining intensity of each cell are scarcely noticed. 2. In the suspension method, in which ascites tumor cells are suspended and reacted with the modified Wattenberg's reagents, all cells reveal relatively weak reaction, but the marked differences of the staining intensity of each cell are observed. 3. In order to clarify the relationship between the permeability of the cell membrane and the intensity of the cytochemical reaction, the cells are treated with the benzalkonium chloride solution. This method is called the permeability increasing suspension method, which reveals a intermediate intensity of the staining between the smear method and the suspension method. Each cell shows a definite difference of the staining. 4. No significant difference is observed between the staining intensity of the suspension method and that of the ascites suspension method in which the ascites supernatant is used as the cytochemical reaction medium instead of the inorganic salts solution. 5. The cells treated with the suspension, permeability increasing suspension and ascites suspension method are able to be successively transplanted into the same strain mouse. Therefore, it may be reasonably assumed that in these three methods the cells are cytochemically reacted in the living condition. However, it is impossible to transplant the cells treated with the smear method. 6. By the observation of the staining patterns of these four methods, it may be assumed that these dehydrogenases in the cells are not always activated and the intensities of their enzymatic activities change according to their life cycle. (a) The DPNase activity remarkably increases in the end of the interphase and abruptly decreases to the lowest level at the metaphase. Then the activity gradually increases, keeping low level throughout the first half of the interphase. This enzyme is localized in the granulations of the cytoplasm and also a little in the cytoplasms of the cells with the high activity. (b) In general, the TPNase activity is slightly lower than that of the DPNase, and shows the same mode of the activity and localization as the latter. (c) The SD activity decreases to the lowest level at the metaphase and remains almost constantly low in the other phases, localizing in the mitochondria. (d) The α-GD activity is generally lower than that of the SD and nearly negative, but shows the same changes of the activity and localization as the latter. 7. When the enzymatic activity of Ehrlich ascites tumor cells is compared with that of the normal ascites cells, the DPNase and TPNase activity are remarkably high, while the SD and α-GD activity are low. en-copyright= kn-copyright= en-aut-name=KawashimaTakao en-aut-sei=Kawashima en-aut-mei=Takao kn-aut-name=河島隆男 kn-aut-sei=河島 kn-aut-mei=隆男 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第1外科教室 END start-ver=1.4 cd-journal=joma no-vol=86 cd-vols= no-issue=11-12 article-no= start-page=543 end-page=551 dt-received= dt-revised= dt-accepted= dt-pub-year=1974 dt-pub=19741230 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the effects of glucocorticoid hormon on lipid and carbohydrate metabolisms Part 1: Clinical and statistical observations of steroid diabetes kn-title=ステロイドホルモンの脂質代謝及び糖質代謝への影響に関する研究 第一編 ステロイド糖尿病の臨床的観察について en-subtitle= kn-subtitle= en-abstract= kn-abstract=SD was seen in 40 (7.8%) out of the 511 Patients who had been treated with glucocorticoid hormon (GCH); most frequently in the patients with leukemia (13 cases) followed by aplastic anemia (12 cases).

Lymphocytes were separated from peripheral blood by cotton columns. In the studies of lymphocyte blastgenesis, 2ml of lymphocyte suspension containing 1.5×10(6) cells/ml in TC-199 supplemented with 15% calf serum were cultured with 200μg PHA for 72 hours at 37℃ in an atmosphere containing 95% air and 5% CO2, and blastoid cells were identified by microscopic examinations. For the MIF test, 2ml of 3×10(6) lymphocytes/ml in TC-199 containing appropriate antigens (human thyroid microsome fraction; 100-500μg wet weight/ml, thyroglobulin; 100μg/ml) were cultured at the same circumstances for 72 hours and then the culture supernatants were examined for the migration of guinea-pig peritoneal macrophages. Migration index (M. I.) was a rate of the area of migration in supernatant with antigen to that without antigen.The rate of blastogenesis of lymphocytes in response to PHA was 32.5±11.2% (mean±SD) in 26 patients with Hashimoto's disease, 49.0±7.6% (mean±SD) in 11 patients with Basedow's disease, and 49.0±8.1% in 14 normal subjects. Significant low response to PHA (the rate under 33%, mean-2SD of normal subjects)was recognized in 14 patients (54% ) with Hashimoto's disease. No patient with Basedow's disease showed abnormal response to PHA. Migration index (MI) with thyroid microsomal fraction was 85.6±19.5% in 40 patients with Hashimoto's disease, 96.6±8.2% in 15 patients with Basedow's disease, and 97.6±10.1% in 18 normal subjects. MI under 77.4% (mean-2SD of normal subjects) was recognized in 12 patients (30%) with Hashimoto's disease. But, MIF production against native or denatured thyroglobulin was negative in all patients examined. There was no definite correlation between MIF production in response to thyroid microsomal fraction and antithyroglobulin antibody titer in patients with Hashimoto's disease.But the patients with positive MIF test showed low or negative thyroglobulin antibody in serum. There were no appearant correlations between MIF test, blastogenesis of lymphocytes with PHA and clinical findings such as age, duration of disease, histology and thyroid function. Above results indicated that T-lymphocyte activity or population of T-lymphocytes responding to PHA was decreased in Hashimoto's disease. On the other hand, it was also shown that the population of lymphocytes sensitized against thyroid autoantigens was present in the peripheral circulation of some patients with this disease. Whether they were T-or B-lymphocytes was not conclusive from the present studies. These sensitized lymphocytes might play important roles in the pathogenesis of Hashimoto's thyroiditis. en-copyright= kn-copyright= en-aut-name=TakehisaYoshiaki en-aut-sei=Takehisa en-aut-mei=Yoshiaki kn-aut-name=竹久義明 kn-aut-sei=竹久 kn-aut-mei=義明 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第三内科学教室 END start-ver=1.4 cd-journal=joma no-vol=87 cd-vols= no-issue=7-8 article-no= start-page=601 end-page=609 dt-received= dt-revised= dt-accepted= dt-pub-year=1975 dt-pub=19750831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=In-vitro Study of Cell-mediated Immunity in Collagen Diseases Part U: Macrophage migration inhibition test (MIT) and leucocyte migration inhition test (LMIT) in rheumatoid arthritis (RA) kn-title=In vitro assayを用いた膠原病における細胞性免疫の検索 第二編 RAにおけるMIT, LMIT en-subtitle= kn-subtitle= en-abstract= kn-abstract=The inflamed synovium of a patient with RA is intensively infiltrated with lymphocytes which often form follicles with aparent germinal centers. The synovial fluid contains aggregates of IgG and its complexes with rheumatoid factor. These evidences point out the immunological significance for the synovial inflammation and also suggest the need to determine whether cell-mediated immunity is concerned with the pathogenesis of RA. In the present study, an attempt has been made to determine whether heat-aggregated IgG and synovial crude extract have acted as antigns capable of causing cellular hypersensitivity in patients with RA. MIT and LMIT have been taken as in-vitro expression of cellular hypersensitivity. The value below the mean percent migration of normal subjects minus 2 SD was considered to be positive. MIT with heat-aggregated IgG was positive in 6 out of 14 patients with RA. Heat-aggregated IgG and synovial crude extract inhibited leucocyte migration in 4 out of 12 patients with RA. Indirect LMIT with heat-aggregated IgG was positive in 4 out of 14 patients with RA and with synovial crude extract in 5 out of 14 patients. None of normal subjects showed positive leucocyte migration inhibition to both antigens. There was no correlation between positive tests and titers of rheumatoid factor, duration, activity of the disease. The data presented above raise the possibility that cell-mediated immune mechanisms play a role in the pathogenesis of RA. en-copyright= kn-copyright= en-aut-name=YanoKeisuke en-aut-sei=Yano en-aut-mei=Keisuke kn-aut-name=矢野啓介 kn-aut-sei=矢野 kn-aut-mei=啓介 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第三内科 END start-ver=1.4 cd-journal=joma no-vol=87 cd-vols= no-issue=5-6 article-no= start-page=543 end-page=548 dt-received= dt-revised= dt-accepted= dt-pub-year=1975 dt-pub=19750630 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Denaturation of Catalase in Livers by SDS Treatment kn-title=肝カタラーゼのSDSによる変性について en-subtitle= kn-subtitle= en-abstract= kn-abstract=When the crystalline beef liver catalase was treated with SDS (sodium n-dodecyl sulfate) or LIS (3, 5-diiodosalicylic acid lithium salt) which is a kind of the anionic surfactant, its catalase activity dwindled and disappeared at last, and its peroxidatic activity was exhibited. It was found by the ultracentrifugal analysis that the molecule of beef liver catalase treated with SDS splited into two subunits with sedimentation constants of about 10S and 2S. The same phenomena as mentioned above were compared in the crude catalase extracts of livers from normal mice and acatalasemia mice. In the crude catalase extracts from both mice, catalase activities dwindled and disappeared in the same way and peroxidatic activities appeared if treated with SDS. But peroxidatic activity of acatalasemia liver extract was higher than that of normal liver extract. It seems that the liver catalase in acatalasemia mouse is more labile by SDS treatment than that in normal mouse, resulting in showing the conformational changes of catalase molecule in acatalasemia mouse liver. en-copyright= kn-copyright= en-aut-name=MizugakiJunko en-aut-sei=Mizugaki en-aut-mei=Junko kn-aut-name=水垣順子 kn-aut-sei=水垣 kn-aut-mei=順子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部公衆衛生学教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=7-8 article-no= start-page=999 end-page=1013 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=197808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Purification and properties of a high molecular weight acid soluble nuclear protein from mouse ascites sarcoma cells kn-title=マウス腹水肉腫細胞核からの高分子量酸可溶性蛋白質の精製とその性質 en-subtitle= kn-subtitle= en-abstract= kn-abstract=A high molecular weight acid soluble nuclear protein (HAN-1) was isolated in a electrophoretically homogeneous state from mouse ascites sarcoma cells (SR-C3H cells) by the exclusion chromatography in Sephacryl S-200 and the DEAE-Sephadex chromatography of the nuclear 0.2M H(2)SO(4) extract. The content of HAN-1 in SR-C3H nuclei was about 4.3% per total histone, the highest among the cell types tested. The molecular weight of HAN-1 was estimated to be 125,000 by SDS-polyacrylamide gel electrophoresis. The amino acid composition of HAN-1 was rich in glutamic acid, alanine, lysine and aspartic acid, the acidic/basic amino acid ratio 1.8. The in vitro RNA synthesizing activity of SR-C3H cell RNA polymerases T and U on a naked DNA template was differentially affected by HAN-1; the reaction with polymerase I was inhibited and that with polymerase U stimulated. en-copyright= kn-copyright= en-aut-name=TsutsuiKimiko en-aut-sei=Tsutsui en-aut-mei=Kimiko kn-aut-name=筒井公子 kn-aut-sei=筒井 kn-aut-mei=公子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部癌源研究施設生化学部門 END
