However, the accuracy of these markers alone is often limited, and most previous reports have evaluated the efficacy of each marker individually. We aimed to improve the diagnostic performance of endoscopic remission (ER) of CD by combining these 3 markers.
Methods We tested the diagnostic ability of various combinations of these 3 markers for endoscopic severity in 230 consecutive patients with CD from September 2014 to July 2023. The modified Simple Endoscopic Score for Crohn's disease (mSES-CD) was used to determine endoscopic severity.
Results Each of the 3 markers was correlated with mSED-CD (LRG: r = 0.69, CRP: r = 0.60, and Fcal: r = 0.67). A combination of 2 of the 3 markers did not increase the diagnostic accuracy of ER. However, by combining all 3 markers, the diagnostic ability for ER was improved in comparison to the diagnostic ability of the 3 individual markers, assuming that ER was obtained if 2 or 3 markers were negative. The sensitivity, specificity, and accuracy were 89%, 83%, and 86%, respectively. Additionally, we established a 2-step method using Fcal values after evaluating the 2 serum markers. This method was most useful for reducing both the patient burden and costs.
Conclusions The newly established 2-step method allowed for a higher accuracy in the non-invasive diagnosis of ER when the 3 markers were combined. en-copyright= kn-copyright= en-aut-name=TakeiKensuke

en-abstract= kn-abstract=We investigated the emotional changes that young patients with breast cancer need to undergo in order to foster relationship-building with their partners by conducting a qualitative descriptive study (March 1 to Nov. 26, 2021) and semi-structured interviews with eight postoperative patients (age 20-40 years) with breast cancer. 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=3 article-no= start-page=147 end-page=155 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Immunometabolic Regulation of Innate Immunity in Systemic Lupus Erythematosus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pathogens or their components can induce long-lasting changes in the behavior of innate immune cells, a process analogous to “training” for future threats or environmental adaptation. However, such training can sometimes have unintended consequences, such as the development of autoimmunity. Systemic lupus erythematosus (SLE) is a chronic and heterogeneous autoimmune disease characterized by the production of autoantibodies and progressive organ damage. Innate immunity plays a central role in its pathogenesis, contributing through impaired clearance of apoptotic cells, excessive type I interferon production, and dysregulated formation of neutrophil extracellular traps. Recent studies have revealed that metabolites and nucleic acids derived from mitochondria, a crucial energy production site, directly regulate type I interferon and anti-inflammatory cytokine production. These insights have fueled interest in targeting metabolic pathways as a novel therapeutic approach for SLE, offering promise for improving long-term patient outcomes. en-copyright= kn-copyright= en-aut-name=WatanabeHaruki en-aut-sei=Watanabe en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=systemic lupus erythematosus kn-keyword=systemic lupus erythematosus en-keyword=interferon kn-keyword=interferon en-keyword=tricarboxylic acid cycle kn-keyword=tricarboxylic acid cycle en-keyword=innate immune memory kn-keyword=innate immune memory en-keyword=trained immunity kn-keyword=trained immunity END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=109 end-page=116 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=Relationship between Personality Traits and Postpartum Depressive Symptoms in Women who Became Pregnant via Infertility Treatment en-subtitle= kn-subtitle= en-abstract= kn-abstract=The status of postpartum depression was elucidated herein with the use of the Edinburgh Postnatal Depression Scale (EPDS) in women in Shikoku, Japan who became pregnant and gave birth after undergoing infertility treatment, including assisted reproductive technology (ART). The assessment was performed during their children’s 4-month health examination. The relationships between postpartum depression and the mothers’ background factors and scores on the Big Five personality traits scale were also examined. Of the Big Five personality traits, the scores for neuroticism were significantly higher in the ART group (n=71) than in the general infertility treatment (n=118) and natural pregnancy (n=872) groups. No significant differences in EPDS scores were seen among these three groups. A logistic regression analysis showed that neuroticism was associated with an EPDS score ≧9 points, (which is suggestive of postpartum depression, ) in all groups. Moreover, although a long-standing marriage had an inhibitory effect on postpartum depression in the natural pregnancy group, no such trend was seen in the ART group, which included many women with long-standing marriages. Particularly for women who become pregnant by ART, an individualized response that pays close attention to the woman’s personality traits is needed. en-copyright= kn-copyright= en-aut-name=AwaiKyoko en-aut-sei=Awai en-aut-mei=Kyoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakatsukaMikiya en-aut-sei=Nakatsuka en-aut-mei=Mikiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=infertility treatment kn-keyword=infertility treatment en-keyword=assisted reproductive technology kn-keyword=assisted reproductive technology en-keyword=postpartum kn-keyword=postpartum en-keyword=postpartum depression kn-keyword=postpartum depression en-keyword=personality trait kn-keyword=personality trait END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=1 article-no= start-page=1 end-page=7 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=Endothelial Cell Polarity in Health and Disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Endothelial cell polarity is fundamental to the organization and function of blood vessels, influencing processes such as angiogenesis, vascular stability, and response to shear stress. This review elaborates on the molecular mechanisms that regulate endothelial cell polarity, focusing on key players like the PAR polarity complex and Rho family GTPases. These pathways coordinate the front–rear, apical–basal and planar polarity of endothelial cells, which are essential for the proper formation and maintenance of vascular structures. In health, endothelial polarity ensures not only the orderly development of blood vessels, with tip cells adopting distinct polarities during angiogenesis, but also ensures proper vascular integrity and function. In disease states, however, disruptions in polarity contribute to pathologies such as coronary artery disease, where altered planar polarity exacerbates atherosclerosis, and cancer, where disrupted polarity in tumor vasculature leads to abnormal vessel growth and function. Understanding cell polarity and its disruption is fundamental not only to comprehending how cells interact with their microenvironment and organize themselves into complex, organ-specific tissues but also to developing novel, targeted, and therapeutic strategies for a range of diseases, from cardiovascular disorders to malignancies, ultimately improving patient outcomes. en-copyright= kn-copyright= en-aut-name=ThihaMoe en-aut-sei=Thiha en-aut-mei=Moe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HikitaTakao en-aut-sei=Hikita en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakayamaMasanori en-aut-sei=Nakayama en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Pathophysiology and Drug Discovery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pathophysiology and Drug Discovery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pathophysiology and Drug Discovery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=blood vessel kn-keyword=blood vessel en-keyword=endothelial cell kn-keyword=endothelial cell en-keyword=cell polarity kn-keyword=cell polarity en-keyword=atherosclerosis kn-keyword=atherosclerosis en-keyword=cancer kn-keyword=cancer END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=2485 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cesarean delivery on child health and development in Japanese nationwide birth cohort en-subtitle= kn-subtitle= en-abstract= kn-abstract=The long-term effects of cesarean delivery (CD) on child health and development remain controversial. This study aimed to investigate these effects using an outcome-wide approach in a Japanese context, where perinatal mortality rates are among the world's lowest. We analyzed data from 2,114 children in a nationwide Japanese birth cohort, linking the 21st Century Longitudinal Survey of Newborns with the Perinatal Research Network database. We examined associations between CD and various health and developmental outcomes up to 9 years of age, including hospitalizations, obesity, and developmental milestones. After adjusting for potential confounders, CD was not significantly associated with most outcomes, including all-cause hospitalization (adjusted risk ratio 1.25, 95% CI 0.997-1.56), obesity at 5.5 and 9 years, and various developmental milestones. Subgroup analyses for multiple births and preterm infants showed some differences in point estimates, but were limited by small sample sizes. CD was not significantly associated with adverse long-term child health or developmental outcomes in this Japanese cohort. These findings provide reassurance regarding CD safety when medically indicated in advanced perinatal care settings. Further research with larger samples and longer follow-up is needed, especially for specific subgroups. en-copyright= kn-copyright= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitsuiTakashi en-aut-sei=Mitsui en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TamaiKei en-aut-sei=Tamai en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HirotaTomoya en-aut-sei=Hirota en-aut-mei=Tomoya 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= 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, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Division of Neonatology, NHO Okayama Medical Center kn-affil= affil-num=4 en-affil=Department of Psychiatry and Behavioral Sciences, UCSF Weill Institute for Neurosciences, University of California San Francisco kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Cesarean delivery kn-keyword=Cesarean delivery en-keyword=Delivery methods kn-keyword=Delivery methods en-keyword=Long-term outcome kn-keyword=Long-term outcome en-keyword=Child development kn-keyword=Child development en-keyword=Outcome-wide approach kn-keyword=Outcome-wide approach END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=2 article-no= start-page=e70168 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Crowned Dens Syndrome Triggered by Dental Treatment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Crowned dens syndrome (CDS) is an important yet often overlooked cause of fever and neck pain, frequently leading to unnecessary examinations and treatments and misdiagnosis as infectious diseases or rheumatic diseases.

We describe a case of CDS triggered by localized physical stress to the neck and emphasize the importance of considering this condition in cases of fever and neck pain following dental treatment. en-copyright= kn-copyright= en-aut-name=MoritaSatoru en-aut-sei=Morita en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MasudaYohei en-aut-sei=Masuda en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SoejimaYoshiaki en-aut-sei=Soejima en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of 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= en-keyword=calcium pyrophosphate crystal deposition disease kn-keyword=calcium pyrophosphate crystal deposition disease en-keyword=crowned dens syndrome kn-keyword=crowned dens syndrome en-keyword=dental treatment kn-keyword=dental treatment en-keyword=fever kn-keyword=fever en-keyword=neck pain kn-keyword=neck pain END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=5 article-no= start-page=413 end-page=421 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=Focal Cerebral Hypoperfusion Detected by Arterial Spin-Labeled Magnetic Resonance Imaging in Patients with Migraine Presenting with Neurological Symptoms Concomitant with or without Headache en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated patients with migraine or migraine variants who exhibited focal cerebral hypoperfusion on arterial spin-labeled (ASL) magnetic resonance (MR) imaging along with neurological symptoms. Fourteen patients with migraine demonstrated focal cerebral hypoperfusion.

Patients with migraine may present with neurological symptoms associated with cortical spreading depression during, after, or even without a headache phase. Additionally, the isolated neurological symptoms may be caused by a pathophysiology identical to that of migraine but without presenting with recurrent headaches. en-copyright= kn-copyright= en-aut-name=KashiharaKenichi en-aut-sei=Kashihara en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IrisawaMinoru en-aut-sei=Irisawa en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakaoWataru en-aut-sei=Takao en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Okayama Neurology Clinic kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama Kyokuto Hospital kn-affil= affil-num=3 en-affil=Division of Radiology, Okayama Kyokuto Hospital kn-affil= en-keyword=arterial spin-labeled magnetic resonance imaging kn-keyword=arterial spin-labeled magnetic resonance imaging en-keyword=cortical spreading depression kn-keyword=cortical spreading depression en-keyword=migraine complex kn-keyword=migraine complex en-keyword=migraine without headache kn-keyword=migraine without headache en-keyword=vertigo kn-keyword=vertigo END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=5 article-no= start-page=357 end-page=362 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=Factors Affecting Dynamic Postural Control Ability in Adolescent Idiopathic Scoliosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Research on postural control in patients with adolescent idiopathic scoliosis (AIS) has focused on static postural control, with few studies assessing dynamic postural control. We aimed to identify factors affecting index of postural stability (IPS), a dynamic postural control parameter, in patients with AIS. The participants comprised 50 female patients with AIS. We measured the IPS using stabilometry to evaluate dynamic postural control ability. We investigated age of the participants, major curve position (thoracic or thoracolumbar/lumbar), Cobb angle, and coronal balance. We then assessed the relationships between stabilometry parameters and other variables. IPS was analyzed with a linear regression model. Coronal balance, major curve position, and age each correlated with dynamic postural control ability. The Cobb angle showed no correlation with any of the parameters. Our results offer new insights into the assessment of postural control in patients with AIS. en-copyright= kn-copyright= en-aut-name=YamawakiRyoko en-aut-sei=Yamawaki en-aut-mei=Ryoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OdaYoshiaki en-aut-sei=Oda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamaneShuhei en-aut-sei=Yamane en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MisawaHaruo en-aut-sei=Misawa en-aut-mei=Haruo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatayamaYoshimi en-aut-sei=Katayama en-aut-mei=Yoshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HamadaMasanori en-aut-sei=Hamada en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=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=Division of Physical Medicine and Rehabilitation, Okayama University kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University kn-affil= affil-num=5 en-affil=Ryusoh Orthopaedic Hospital kn-affil= affil-num=6 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University kn-affil= affil-num=7 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University kn-affil= affil-num=8 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University kn-affil= en-keyword=adolescent idiopathic scoliosis kn-keyword=adolescent idiopathic scoliosis en-keyword=postural control kn-keyword=postural control en-keyword=coronal balance kn-keyword=coronal balance en-keyword=index of postural stability kn-keyword=index of postural stability en-keyword=stabilometry kn-keyword=stabilometry END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=17 article-no= start-page=2824 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240823 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cyclic Oligosaccharide-Induced Modulation of Immunoglobulin A Reactivity to Gut Bacteria Contributes to Alterations in the Bacterial Community Structure en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immunoglobulin A (IgA) is a major gut antibody that coats commensal gut bacteria and contributes to shaping a stable gut bacterial composition. Although previous studies have shown that cyclic oligosaccharides, including cyclic nigerosyl-1,6-nigerose (CNN) and cyclodextrins (CDs, including alpha CD, beta CD, and gamma CD), alter the gut bacterial composition, it remains unclear whether cyclic oligosaccharides modify the IgA coating of gut bacteria, which relates to cyclic oligosaccharide-induced alteration of the gut bacterial composition. To address this issue, mice were maintained for 12 weeks on diets containing CNN, alpha CD, beta CD, or gamma CD; the animals' feces were evaluated for their bacterial composition and the IgA coating index (ICI), a measure of the degree of IgA coating of bacteria. We observed that the intake of each cyclic oligosaccharide altered the gut bacterial composition, with changes in the ICI found at both the phylum and genus levels. The ICI for Bacillota, Lachnospiraceae NK4A136 group, UC Lachnospiraceae, and Tuzzerella were significantly and positively correlated with the relative abundance (RA) in total bacteria for these bacteria; in contrast, significant correlations were not seen for other phyla and genera. Our observations suggest that cyclic oligosaccharide-induced modulation of the IgA coating of gut bacteria may partly relate to changes in the community structure of the gut bacteria. en-copyright= kn-copyright= en-aut-name=MiyamotoTaisei en-aut-sei=Miyamoto en-aut-mei=Taisei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsurutaTakeshi en-aut-sei=Tsuruta en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TeraokaMao en-aut-sei=Teraoka en-aut-mei=Mao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangTianyang en-aut-sei=Wang en-aut-mei=Tianyang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishinoNaoki en-aut-sei=Nishino en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=cyclic oligosaccharides kn-keyword=cyclic oligosaccharides en-keyword=gut bacteria kn-keyword=gut bacteria en-keyword=immunoglobulin A kn-keyword=immunoglobulin A END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=32 article-no= start-page=12686 end-page=12694 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240710 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Boosting charge separation in organic photovoltaics: unveiling dipole moment variations in excited non-fullerene acceptor layers en-subtitle= kn-subtitle= en-abstract= kn-abstract=The power conversion efficiency (PCE) of organic photovoltaics (OPVs) has reached more than 19% due to the rapid development of non-fullerene acceptors (NFAs). To compete with the PCEs (26%) of commercialized silicon-based inorganic photovoltaics, the drawback of OPVs should be minimized. This drawback is the intrinsic large loss of open-circuit voltage; however, a general approach to this issue remains elusive. Here, we report a discovery regarding highly efficient NFAs, specifically ITIC. We found that charge-transfer (CT) and charge dissociation (CD) can occur even in a neat ITIC film without the donor layer. This is surprising, as these processes were previously believed to take place exclusively at donor/acceptor heterojunctions. Femtosecond time-resolved visible to mid-infrared measurements revealed that in the neat ITIC layers, the intermolecular CT immediately proceeds after photoirradiation (<0.1 ps) to form weakly-bound excitons with a binding energy of 0.3 eV, which are further dissociated into free electrons and holes with a time-constant of 56 ps. Theoretical calculations indicate that stacking faults in ITIC (i.e., V-type molecular stacking) induce instantaneous intermolecular CT and CD in the neat ITIC layer. In contrast, J-type stacking does not support such CT and CD. This previously unknown pathway is triggered by the larger dipole moment change on the excited state generated at the lower symmetric V-type molecular stacking of ITIC. This is in sharp contrast with the need of sufficient energy offset for CT and CD at the donor-acceptor heterojunction, leading to the significant voltage loss in conventional OPVs. These results demonstrate that the rational molecular design of NFAs can increase the local dipole moment change on the excited state within the NFA layer. This finding paves the way for a groundbreaking route toward the commercialization of OPVs. en-copyright= kn-copyright= en-aut-name=YamakataAkira en-aut-sei=Yamakata en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatoKosaku en-aut-sei=Kato en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UrakamiTakumi en-aut-sei=Urakami en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsujimuraSota en-aut-sei=Tsujimura en-aut-mei=Sota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurayamaKasumi en-aut-sei=Murayama en-aut-mei=Kasumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HigashiMasahiro en-aut-sei=Higashi en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SatoHirofumi en-aut-sei=Sato en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KoboriYasuhiro en-aut-sei=Kobori en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UmeyamaTomokazu en-aut-sei=Umeyama en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ImahoriHiroshi en-aut-sei=Imahori en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Molecular Engineering, Graduate School of Engineering, Kyoto University kn-affil= affil-num=4 en-affil=Department of Chemistry, Graduate School of Science, Kobe University kn-affil= affil-num=5 en-affil=Department of Chemistry, Graduate School of Science, Kobe University kn-affil= affil-num=6 en-affil=Department of Complex Systems Science, Graduate School of Informatics, Nagoya University kn-affil= affil-num=7 en-affil=Department of Molecular Engineering, Graduate School of Engineering, Kyoto University kn-affil= affil-num=8 en-affil=Department of Chemistry, Graduate School of Science, Kobe University kn-affil= affil-num=9 en-affil=Department of Applied Chemistry, Graduate School of Engineering, University of Hyogo kn-affil= affil-num=10 en-affil=Department of Molecular Engineering, Graduate School of Engineering, Kyoto University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=15139 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240702 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genetic background influences mineral accumulation in rice straw and grains under different soil pH conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mineral element accumulation in plants is influenced by soil conditions and varietal factors. We investigated the dynamic accumulation of 12 elements in straw at the flowering stage and in grains at the mature stage in eight rice varieties with different genetic backgrounds (Japonica, Indica, and admixture) and flowering times (early, middle, and late) grown in soil with various pH levels. In straw, Cd, As, Mn, Zn, Ca, Mg, and Cu accumulation was influenced by both soil pH and varietal factors, whereas P, Mo, and K accumulation was influenced by pH, and Fe and Ni accumulation was affected by varietal factors. In grains, Cd, As, Mn, Cu, Ni, Mo, Ca, and Mg accumulation was influenced by both pH and varietal factors, whereas Zn, Fe, and P accumulation was affected by varietal factors, and K accumulation was not altered. Only As, Mn, Ca and Mg showed similar trends in the straw and grains, whereas the pH responses of Zn, P, K, and Ni differed between them. pH and flowering time had synergistic effects on Cd, Zn, and Mn in straw and on Cd, Ni, Mo, and Mn in grains. Soil pH is a major factor influencing mineral uptake in rice straw and grains, and genetic factors, flowering stage factors, and their interaction with soil pH contribute in a combined manner. en-copyright= kn-copyright= en-aut-name=YamamotoToshio en-aut-sei=Yamamoto en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KashiharaKazunari en-aut-sei=Kashihara en-aut-mei=Kazunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FurutaTomoyuki en-aut-sei=Furuta en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZhangQian en-aut-sei=Zhang en-aut-mei=Qian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YuEn en-aut-sei=Yu en-aut-mei=En kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MaJian Feng en-aut-sei=Ma en-aut-mei=Jian Feng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=123 end-page=134 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=Sigle Agent of Posttransplant Cyclophosphamide Without Calcineurin Inhibitor Controls Severity of Experimental Chronic GVHD en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chronic graft-versus-host disease (GVHD) is a major cause of late death and morbidity following allogeneic hematopoietic cell transplantation (HCT), but its pathogenesis remains unclear. Recently, haplo-identical HCT with post-transplant cyclophosphamide (Haplo-HCT with PTCY) was found to achieve a low incidence rate of acute GVHD and chronic GVHD. However, while the pathogenesis of acute GVHD following Haplo-HCT with PTCY has been well investigated, that of chronic GVHD remains to be elucidated, especially in HLA-matched HCT with PTCY. Based on its safety profile, PTCY is currently applied for the human leucocyte antigen (HLA)-matched HCT setting. Here, we investigated the mechanisms of chronic GVHD following HLA-matched HCT with PTCY using a well-defined mouse chronic GVHD model. PTCY attenuated clinical and pathological chronic GVHD by suppressing effector T-cells and preserving regulatory T-cells compared with a control group. Additionally, we demonstrated that cyclosporine A (CsA) did not show any additional positive effects on attenuation of GVHD in PTCY-treated recipients. These results suggest that monotherapy with PTCY without CsA could be a promising strategy for the prevention of chronic GVHD following HLA-matched HCT. en-copyright= kn-copyright= en-aut-name=SaekiKyosuke en-aut-sei=Saeki en-aut-mei=Kyosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=SeikeKeisuke en-aut-sei=Seike en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KuroiTaiga en-aut-sei=Kuroi en-aut-mei=Taiga kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuokaKen-ichi en-aut-sei=Matsuoka en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 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 Hospital kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Hospital 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 Hospital kn-affil= affil-num=6 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Division of Transfusion, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=GVHD kn-keyword=GVHD en-keyword=posttransplant cyclophosphamide kn-keyword=posttransplant cyclophosphamide en-keyword=hematopoietic cell transplantation kn-keyword=hematopoietic cell transplantation en-keyword=HLA-identical kn-keyword=HLA-identical 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=77 cd-vols= no-issue=6 article-no= start-page=635 end-page=645 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Nutritional Support Combined with Neuromuscular Electrical Stimulation on Muscle Strength and Thickness: A Randomized Controlled Trial in Healthy Young Adult Males en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the management of post-injury patients with activity limitations, methods to prevent musculoskeletal disorders and hasten recovery are important. This randomized controlled, single-blinded study was a preliminary investigation of the combined effect of nutritional support with neuromuscular electrical stimulation (NMES) on muscle strength and thickness. Healthy young adult males (median age, 21 years) were enrolled; each of their hands was randomly assigned to one of the following four groups: Placebo, Nutrition, NMES, and Nutrition + NMES. All participants received whey protein or placebo (3x/week for 6 weeks) and NMES training (3x/week for 6 weeks) on the abductor digiti minimi (ADM) muscle of either the left or right hand. ADM muscle strength and thickness were analyzed at baseline and at week 7. We analyzed 38 hands (9 Placebo, 10 Nutrition, 9 NMES, 10 Nutrition + NMES). There was significantly greater muscle strengthening in the Nutrition + NMES group compared to the Placebo group or the NMES group, but no significant difference in gain of muscle thickness. The combined intervention may be effective in improving muscle strength. Future clinical trials targeting various muscles after sports-related injuries are warranted. en-copyright= kn-copyright= en-aut-name=IkedaTomohiro en-aut-sei=Ikeda en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkamuraKazunori en-aut-sei=Okamura en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HasegawaMasaki en-aut-sei=Hasegawa en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaSatoshi en-aut-sei=Tanaka en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KanaiShusaku en-aut-sei=Kanai en-aut-mei=Shusaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Physical Therapy, Faculty of Health and Welfare, Prefectural University of Hiroshima kn-affil= affil-num=3 en-affil=Department of Physical Therapy, Faculty of Health and Welfare, Prefectural University of Hiroshima kn-affil= affil-num=4 en-affil=Department of Physical Therapy, Faculty of Health and Welfare, Prefectural University of Hiroshima kn-affil= affil-num=5 en-affil=Department of Physical Therapy, Faculty of Health and Welfare, Prefectural University of Hiroshima kn-affil= en-keyword=whey protein kn-keyword=whey protein en-keyword=electrical stimulation kn-keyword=electrical stimulation en-keyword=muscle strength kn-keyword=muscle strength en-keyword=healthy volunteers kn-keyword=healthy volunteers END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=6 article-no= start-page=619 end-page=625 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Trochanteric Claw Plate Fixation for Greater Trochanteric Fracture or Osteotomy in Total Hip Arthroplasty en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study retrospectively evaluated 41 consecutive open reductions and internal fixations following primary or revision total hip arthroplasty, which required trochanteric claw plate fixation for greater trochanteric fracture or osteotomy between January 2008 and December 2020. The mean duration of clinical follow-up was 4.2 years (range, 1-13 years). The patients included 13 men and 28 women, with a mean age of 68 years (range, 32-87 years). The indications for intervention included trochanteric osteotomy, intraoperative fracture, and non-union including postoperative fracture in 6, 9, and 26 cases, respectively. The mean Merle d’Aubigné Clinical Score improved from 9.4 points (range, 5-15 points) pre-operatively, to 14.3 points (range, 9-18 points) at the last follow-up. Bone union occurred in 35 cases (85%), while implant breakage occurred in four cases. At the last follow-up, the mean Merle d’Aubigné Clinical Scores of bone union and non-union were 15.3 and 14.1, respectively (p=0.48). The Kaplan-Meier survival rate, with the endpoint being revision surgery for pain, non-union, dislocation, or implant breakage, at 10 years was 80.0% (95% confidence interval: 62.6-97.4%). Greater trochanteric fixation using a trochanteric claw plate yielded successful results. en-copyright= kn-copyright= en-aut-name=OeKenichi en-aut-sei=Oe en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IidaHirokazu en-aut-sei=Iida en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SogawaShohei en-aut-sei=Sogawa en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KobayashiFumito en-aut-sei=Kobayashi en-aut-mei=Fumito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakamuraTomohisa en-aut-sei=Nakamura en-aut-mei=Tomohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SaitoTakanori en-aut-sei=Saito en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Kansai Medical University kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Kansai Medical University kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Kansai Medical University kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Kansai Medical University kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Kansai Medical University kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Kansai Medical University kn-affil= en-keyword=greater trochanteric fracture kn-keyword=greater trochanteric fracture en-keyword=trochanteric osteotomy kn-keyword=trochanteric osteotomy en-keyword=claw plate kn-keyword=claw plate en-keyword=total hip arthroplasty kn-keyword=total hip arthroplasty END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=6 article-no= start-page=595 end-page=605 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Concomitant Use of Multiple Nephrotoxins including Renal Hypoperfusion Medications Causes Vancomycin-Associated Nephrotoxicity: Combined Retrospective Analyses of Two Real-World Databases en-subtitle= kn-subtitle= en-abstract= kn-abstract=There is a growing concern about the relationship between vancomycin-associated nephrotoxicity (VAN) and concomitant use of nephrotoxins.

Next, electronic medical records (EMRs) of patients who received vancomycin (VCM) at Tokushima University Hospital between January 2006 and March 2019 were examined to confirm the FAERS analysis. An elevated reporting odds ratio (ROR) was observed with increases in the number of nephrotoxins administered (VCM + one nephrotoxin, adjusted ROR (95% confidence interval [CI]) 1.67 [1.51-1.85]; VCM + ≥2 nephrotoxins, adjusted ROR [95% CI] 1.54 [1.37-1.73]) in FAERS. EMRs analysis showed that the number of nephrotoxins was associated with higher incidences of VAN [odds ratio: 1.99; 95% CI: 1.42-2.78]. Overall, concomitant use of nephrotoxins was associated with an increased incidence of VAN, especially when at least one of those nephrotoxins was a renal hypoperfusion medication (furosemide, non-steroidal anti-inflammatory drugs, and vasopressors). The concomitant use of multiple nephrotoxins, especially including renal hypoperfusion medication, should be avoided to prevent VAN. en-copyright= kn-copyright= en-aut-name=BandoTakashi

kn-title=Highly Stretchable Stress-Strain Sensor from Elastomer Nanocomposites with Movable Cross-links and Ketjenblack en-subtitle= kn-subtitle= en-abstract= kn-abstract=Practical applications like very thin stress-strain sensors require high strength, stretchability, and conductivity, simultaneously. One of the approaches is improving the toughness of the stress-strain sensing materials. Polymeric materials with movable cross-links in which the polymer chain penetrates the cavity of cyclodextrin (CD) demonstrate enhanced strength and stretchability, simultaneously. We designed two approaches that utilize elastomer nanocomposites with movable cross-links and carbon filler (ketjenblack, KB). One approach is mixing SC (a single movable cross-network material), a linear polymer (poly(ethyl acrylate), PEA), and KB to obtain their composite. The electrical resistance increases proportionally with tensile strain, leading to the application of this composite as a stress- strain sensor. The responses of this material are stable for over 100 loading and unloading cycles. The other approach is a composite made with KB and a movable cross-network elastomer for knitting dissimilar polymers (KP), where movable cross-links connect the CD-modified polystyrene (PSCD) and PEA. The obtained composite acts as a highly sensitive stress-strain sensor that exhibits an exponential increase in resistance with increasing tensile strain due to the polymer dethreading from the CD rings. The designed preparations of highly repeatable or highly responsive stress-strain sensors with good mechanical properties can help broaden their application in electrical devices. en-copyright=

precursor acute lymphoblastic leukemia (Ph+ALL) presented with an osteolytic lesion in his right upper arm. Tyrosine kinase inhibitors (TKIs) such as imatinib and dasatinib are an essential component throughout the course of treatment for Ph+ALL. However, TKIs are reported to affect the bone metabolism. In the treatment course of the current patient, the osteolytic lesion quickly improved despite the continuous use of TKIs, even during the concomitant use of corticosteroids. This suggests that TKIs can be safely given with concomitant corticosteroids to children with Ph+ALL, even when osteolytic lesions are present. en-copyright= kn-copyright= en-aut-name=ShiwakuTakahiro en-aut-sei=Shiwaku en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshidaHisashi en-aut-sei=Ishida en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TatebeYasuhisa en-aut-sei=Tatebe en-aut-mei=Yasuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TamefusaKosuke en-aut-sei=Tamefusa en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OchiMotoharu en-aut-sei=Ochi en-aut-mei=Motoharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiwaraKaori en-aut-sei=Fujiwara en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KuboToshihide en-aut-sei=Kubo en-aut-mei=Toshihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=WashioKana en-aut-sei=Washio en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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 Pharmacy, 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=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Pediatrics, National Hospital Organization Okayama Medical Center kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= en-keyword=acute lymphoblastic leukemia kn-keyword=acute lymphoblastic leukemia en-keyword=children kn-keyword=children en-keyword=tyrosine kinase inhibitor kn-keyword=tyrosine kinase inhibitor en-keyword=osteolysis kn-keyword=osteolysis END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=4 article-no= start-page=359 end-page=364 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Changes in TRPV1 Receptor, CGRP, and BDNF Expression in Rat Dorsal Root Ganglion with Resiniferatoxin-Induced Neuropathic Pain: Modulation by Pulsed Radiofrequency Applied to the Sciatic Nerve en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pulsed radiofrequency (PRF) is a safe method of treating neuropathic pain by generating intermittent electric fields at the needle tip. Resiniferatoxin (RTX) is an ultrapotent agonist of transient receptor potential vanilloid subtype-1 (TRPV1) receptors. We investigated the mechanism of PRF using a rat model of RTX-induced neuropathic pain. After administering RTX intraperitoneally, PRF was applied to the right sciatic nerve. We observed the changes in TRPV1, calcitonin gene-related peptide (CGRP), and brain-derived neurotrophic factor (BDNF) in the dorsal root ganglia by western blotting. Expressions of TRPV1 and CGRP were significantly lower in the contralateral (RTX-treated, PRF-untreated) tissue than in control rats (p<0.0001 and p<0.0001, respectively) and the ipsilateral tissues (p<0.0001 and p<0.0001, respectively). BDNF levels were significantly higher in the contralateral tissues than in the control rats (p<0.0001) and the ipsilateral tissues (p<0.0001). These results suggest that, while TRPV1 and CGRP are decreased by RTX-induced neuronal damage, increased BDNF levels result in pain development. PRF may promote recovery from neuronal damage with concomitant restoration of TRPV1 and CGRP, and exert its analgesic effect by reversing BDNF increase. Further research is required to understand the role of TRPV1 and CGRP restoration in improving mechanical allodynia. en-copyright= kn-copyright= en-aut-name=KoshidaTomohiro en-aut-sei=Koshida en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MarutaToyoaki en-aut-sei=Maruta en-aut-mei=Toyoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaNobuhiko en-aut-sei=Tanaka en-aut-mei=Nobuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HidakaKotaro en-aut-sei=Hidaka en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KurogiMio en-aut-sei=Kurogi en-aut-mei=Mio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NemotoTakayuki en-aut-sei=Nemoto en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YanagitaToshihiko en-aut-sei=Yanagita en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakeyaRyu en-aut-sei=Takeya en-aut-mei=Ryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TsuneyoshiIsao en-aut-sei=Tsuneyoshi en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Pain Clinic, Faculty of Medicine, University of Miyazaki kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Pain Clinic, Faculty of Medicine, University of Miyazaki kn-affil= affil-num=3 en-affil=Tanaka homecare clinic kn-affil= affil-num=4 en-affil=Department of Anesthesiology and Pain Clinic, Faculty of Medicine, University of Miyazaki kn-affil= affil-num=5 en-affil=Department of Anesthesiology and Pain Clinic, Faculty of Medicine, University of Miyazaki kn-affil= affil-num=6 en-affil=Department of Pharmacology, Faculty of Medicine, Fukuoka University kn-affil= affil-num=7 en-affil=Department of Clinical Pharmacology, School of Nursing, Faculty of Medicine, University of Miyazaki kn-affil= affil-num=8 en-affil=Department of Pharmacology, Faculty of Medicine, University of Miyazaki kn-affil= affil-num=9 en-affil=Department of Anesthesiology and Pain Clinic, Faculty of Medicine, University of Miyazaki kn-affil= en-keyword=pulsed radiofrequency kn-keyword=pulsed radiofrequency en-keyword=resiniferatoxin kn-keyword=resiniferatoxin en-keyword=transient receptor potential vanilloid subtype-1 (TRPV1) kn-keyword=transient receptor potential vanilloid subtype-1 (TRPV1) en-keyword=calcitonin gene-related peptide (CGRP) kn-keyword=calcitonin gene-related peptide (CGRP) en-keyword=brain-derived neurotrophic factor (BDNF) kn-keyword=brain-derived neurotrophic factor (BDNF) END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=3 article-no= start-page=323 end-page=330 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Utility of Comprehensive Genomic Profiling for Precise Diagnosis of Pediatric-Type Diffuse High-Grade Glioma en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the current World Health Organization classification of central nervous system tumors, comprehensive genetic and epigenetic analyses are considered essential for precise diagnosis. A 14-year-old male patient who presented with a cerebellar tumor was initially diagnosed with glioblastoma and treated with radiation and concomitant temozolomide chemotherapy after resection. During maintenance temozolomide therapy, a new contrast-enhanced lesion developed in the bottom of the cavity formed by the resection. A second surgery was performed, but the histological findings in specimens from the second surgery were different from those of the first surgery. Although genome-wide DNA methylation profiling was conducted using frozen tissue for a precise diagnosis, the proportion of tumor cells was insufficient and only normal cerebellum was observed. We then performed comprehensive genetic analysis using formalin-fixed paraffin-embedded sections, which revealed MYCN amplification without alteration of IDH1, IDH2, or Histone H3. Finally, the patient was diagnosed with pediatric-type diffuse high-grade glioma, H3-wildtype and IDH-wildtype. In conclusion, comprehensive genetic and epigenetic analysis should be considered in pediatric brain tumor cases. en-copyright= kn-copyright= en-aut-name=MakinoKeigo en-aut-sei=Makino en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshidaJoji en-aut-sei=Ishida en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiranoShuichiro en-aut-sei=Hirano en-aut-mei=Shuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SurugaYasuki en-aut-sei=Suruga en-aut-mei=Yasuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WashioKana en-aut-sei=Washio en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishidaKenji en-aut-sei=Nishida en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=TomidaShuta en-aut-sei=Tomida en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Departments of Pediatrics, Okayama University Hospital kn-affil= affil-num=8 en-affil=Departments of Pathology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Departments of Pathology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=comprehensive genomic profiling kn-keyword=comprehensive genomic profiling en-keyword=pediatric brain tumor kn-keyword=pediatric brain tumor en-keyword=genome-wide DNA methylation kn-keyword=genome-wide DNA methylation en-keyword=MYCN kn-keyword=MYCN END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=3 article-no= start-page=301 end-page=309 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Associations between Comorbidities and Acute Exacerbation of Interstitial Lung Disease after Primary Lung Cancer Surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract=Acute exacerbation (AE) of interstitial lung disease (ILD) is a severe complication of lung resection in lung cancer patients with ILD (LC-ILD). This study aimed to assess the predictive value of comorbidities other than ILD for postoperative AE in patients with LC-ILD. We retrospectively evaluated 68 patients with LC-ILD who had undergone lung resection. We classified them into two groups: those who had developed postoperative AE within 30 days after resection and those who had not. We analyzed patient characteristics, high-resolution computed tomography findings, clinical data, pulmonary function, and intraoperative data. The incidence of postoperative AEs was 11.8%. In univariate analysis, performance status (PS), honeycombing, forced vital capacity (FVC), and high hemoglobin A1c (HbA1c) levels without comorbidities were significantly associated with postoperative AE. Patients were divided into two groups according to cutoff levels of those four variables as determined by receiver operating characteristic curves, revealing that the rates of patients without postoperative AE differed significantly between groups. The present results suggested that preoperative comorbidities other than ILD were not risk factors for postoperative AE in patients with LC-ILD. However, a high preoperative HbA1c level, poor PS, low FVC, and honeycombing may be associated with postoperative AE of LC-ILD. en-copyright= kn-copyright= en-aut-name=KatoTakahide en-aut-sei=Kato en-aut-mei=Takahide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyoshiSeigo en-aut-sei=Miyoshi en-aut-mei=Seigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamadaChizuru en-aut-sei=Hamada en-aut-mei=Chizuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SanoYoshifumi en-aut-sei=Sano en-aut-mei=Yoshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NogamiNaoyuki en-aut-sei=Nogami en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamaguchiOsamu en-aut-sei=Yamaguchi en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HamaguchiNaohiko en-aut-sei=Hamaguchi en-aut-mei=Naohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Cardiology, Pulmonology, Hypertension and Nephrology, Ehime University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Cardiology, Pulmonology, Hypertension and Nephrology, Ehime University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Cardiology, Pulmonology, Hypertension and Nephrology, Ehime University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Cardiovascular and Thoracic Surgery, Ehime University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Community Medicine, Pulmonology and Cardiology, Ehime University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Cardiology, Pulmonology, Hypertension and Nephrology, Ehime University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Cardiology, Pulmonology, Hypertension and Nephrology, Ehime University Graduate School of Medicine kn-affil= en-keyword=lung cancer kn-keyword=lung cancer en-keyword=interstitial lung disease kn-keyword=interstitial lung disease en-keyword=acute exacerbation kn-keyword=acute exacerbation en-keyword=comorbidity kn-keyword=comorbidity END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=3 article-no= start-page=263 end-page=272 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Early Fluid Balance Is Associated with 90-Day Mortality in Patients Receiving Continuous Renal Replacement Therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Continuous renal replacement therapy (CRRT) is widely used to control fluid balance, but the optimal fluid balance to improve the prognosis of patients remains debated. Appropriate fluid management may depend on hemodynamic status. We investigated the association between 90-day mortality and fluid balance/mean arterial pressure (MAP) in patients receiving CRRT. This single-center retrospective study was conducted between May 2018 and March 2021. Based on the cumulative fluid balance at 72 h after initiation of CRRT, the cases were divided into negative (< 0 mL) and positive (> 0 mL) fluid balance groups. Ninety-day mortality was higher in the positive fluid balance group (p=0.009). At 4 h before and after CRRT initiation, the mean MAP was lower in the positive fluid balance group (p<0.05). After multivariate cox adjustment, 72-h positive fluid balance was independently associated with 90-day mortality (p=0.004). In addition, the cumulative fluid balance was associated with 90-day mortality (p<0.05) in cases without shock, high APACHE II score, sepsis, dialysis dependence, or vasopressor use. A 72-h positive fluid balance was associated with 90-day mortality in patients receiving CRRT. en-copyright= kn-copyright= en-aut-name=GuoYusheng en-aut-sei=Guo en-aut-mei=Yusheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KosakaJunko en-aut-sei=Kosaka en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=fluid management kn-keyword=fluid management en-keyword=continuous renal replacement therapy kn-keyword=continuous renal replacement therapy en-keyword=mortality kn-keyword=mortality en-keyword=mean arterial pressure kn-keyword=mean arterial pressure en-keyword=daily cumulative fluid balance kn-keyword=daily cumulative fluid balance END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=2 article-no= start-page=161 end-page=167 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202304 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prolonged Double-Low Time and the Incidence of Postoperative Delirium in Surgical ICU Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=An intraoperative double-low condition is defined as concurrent low values for bispectral index (BIS) and mean arterial pressure (MAP), and may predict perioperative outcomes. We hypothesized that prolonged double-low times might be associated with an increased incidence of postoperative delirium. We conducted a single-center retrospective observational study on patients who had been admitted to our hospital’s intensive care unit (ICU) after surgery and whose BIS and MAP data had been recorded during general anesthesia. The primary outcome was the incidence of postoperative delirium. A double-low condition was defined as BIS < 45 and MAP <75 mmHg. The total double-low time was calculated in 1-min increments and used to divide the patients into quintiles. Multiple logistic regression analyses were conducted. Among the 334 patients included in the study, the incidence of postoperative delirium was 15.6% (n=52). Multiple logistic regression analysis revealed that a prolonged double-low time, defined as a total double-low time of > 42 min (i.e., third, fourth, and fifth quintiles), was significantly associated with an increased incidence of postoperative delirium (adjusted odds ratio: 2.61, 95% confidence interval: 1.27-5.37, p=0.009). Prolonged double-low time during general anesthesia was independently associated with an increased incidence of postoperative delirium in surgical ICU patients. en-copyright= kn-copyright= en-aut-name=YamanoiTomoko en-aut-sei=Yamanoi en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiSatoshi en-aut-sei=Suzuki en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KakuRyuji en-aut-sei=Kaku en-aut-mei=Ryuji 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 Intensive Care Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Anesthesiology, Mie University Hospital 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=postoperative delirium kn-keyword=postoperative delirium en-keyword=bispectral index kn-keyword=bispectral index en-keyword=hypotension kn-keyword=hypotension en-keyword=double-low condition kn-keyword=double-low condition en-keyword=general anesthesia kn-keyword=general anesthesia END start-ver=1.4 cd-journal=joma no-vol=101 cd-vols= no-issue=50 article-no= start-page=e32424 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221216 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Safety and efficacy of capsule endoscopy for patients with newly diagnosed Crohn's disease: A multicenter retrospective study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Crohn's disease (CD) is a chronic inflammatory disease that develops at a young age and frequently leads to intestinal resection. Capsule endoscopy (CE) can directly and non-invasively inspect the entire small bowel mucosa. We suspected that CE could be a good diagnostic tool for detecting CD in young patients. The aim of this study was to investigate the safety and efficacy of CE in patients with newly diagnosed CD and to evaluate the CE findings, especially in the upper small bowel of young patients. We retrospectively investigated 32 patients with newly diagnosed CD from 5 institutions. Patient characteristics, clinical course, and characteristics of CE findings were analyzed. The total small intestine observation rate was 93%, and the retention rate was 3% (1/32). No abnormality was identified by ileocolonoscopy in 46% (15/32), and transition of small bowel lesions (TSL) was found in 35% (12/34) of the patients. The frequency of longitudinal ulcers and cobblestones in the upper small intestine was significantly higher in younger patients (<= 20 years). Moreover, positive findings in the upper small intestine were predominantly observed in younger patients (<= 20 years). CE for patients with newly diagnosed CD was safe and useful, especially for the detection of upper small bowel lesions in young patients. en-copyright= kn-copyright= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkaShiro en-aut-sei=Oka en-aut-mei=Shiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShiotaniAkiko en-aut-sei=Shiotani en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HashimotoShinichi en-aut-sei=Hashimoto en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahashiSakuma en-aut-sei=Takahashi en-aut-mei=Sakuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HandaOsamu en-aut-sei=Handa en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakamiTaro en-aut-sei=Takami en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=InabaTomoki en-aut-sei=Inaba en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaShinji en-aut-sei=Tanaka en-aut-mei=Shinji 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 Metabolism, Hiroshima University Hospital kn-affil= affil-num=3 en-affil=Department of Internal Medicine, Division of Gastroenterology, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Yamaguchi University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Gastroenterology, Kagawa Prefectural Central Hospital kn-affil= affil-num=6 en-affil=Department of Internal Medicine, Division of Gastroenterology, Kawasaki Medical School kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Yamaguchi University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Gastroenterology, Kagawa Prefectural Central Hospital 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 Metabolism, Hiroshima University Hospital kn-affil= en-keyword=capsule endoscopy kn-keyword=capsule endoscopy en-keyword=Crohn's disease kn-keyword=Crohn's disease en-keyword=upper small intestine kn-keyword=upper small intestine en-keyword=young patients kn-keyword=young patients END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=755 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Metformin and Its Immune-Mediated Effects in Various Diseases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Metformin has been a long-standing prescribed drug for treatment of type 2 diabetes (T2D) and its beneficial effects on virus infection, autoimmune diseases, aging and cancers are also recognized. Metformin modulates the differentiation and activation of various immune-mediated cells such as CD4+ and CD+8 T cells. The activation of adenosine 5 '-monophosphate-activated protein kinase (AMPK) and mammalian target of rapamycin complex 1 (mTORC1) pathway may be involved in this process. Recent studies using Extracellular Flux Analyzer demonstrated that metformin alters the activities of glycolysis, oxidative phosphorylation (OXPHOS), lipid oxidation, and glutaminolysis, which tightly link to the modulation of cytokine production in CD4+ and CD+8 T cells in various disease states, such as virus infection, autoimmune diseases, aging and cancers. en-copyright= kn-copyright= en-aut-name=NojimaIchiro en-aut-sei=Nojima en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=CD8 T cells kn-keyword=CD8 T cells en-keyword=AMPK kn-keyword=AMPK en-keyword=mTORC kn-keyword=mTORC en-keyword=OXPHOS kn-keyword=OXPHOS en-keyword=autoimmune disease kn-keyword=autoimmune disease en-keyword=aging kn-keyword=aging en-keyword=cancer kn-keyword=cancer END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=6 article-no= start-page=749 end-page=754 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Salvage Surgery for Symptomatic Recurrence of Retro-Odontoid Pseudotumor after a C1 Laminectomy en-subtitle= kn-subtitle= en-abstract= kn-abstract=We provide the first report of successful salvage surgery for a post-C1 laminectomy symptomatic recurrence of a retro-odontoid pseudotumor (ROP) that caused myelopathy.

We present a case in which cerebrospinal fluid drainage (CSFD) and permissive hypertension were used for treatment of paraplegia. When the patient showed complete bilateral paraplegia after operation for AADA, we immediately began CSFD and maintained mean arterial blood pressure at over 90 mmHg. His neurological deficit gradually recovered, and he was eventually able to walk without support. The combination of CSFD and permissive hypertension could be a first-line emergent treatment for postoperative paraplegia after AADA surgery. en-copyright= kn-copyright= en-aut-name=YamaokaMasakazu en-aut-sei=Yamaoka en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoYumi en-aut-sei=Yamamoto en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MinamiEriko en-aut-sei=Minami en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Anesthesiology, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Critical Care Medicine, Hiroshima Citizens Hospital kn-affil= affil-num=3 en-affil=Department of Anesthesiology, Japanese Red Cross Society Himeji Hospital kn-affil= en-keyword=paraplegia kn-keyword=paraplegia en-keyword=acute aortic dissection kn-keyword=acute aortic dissection en-keyword=cerebrospinal drainage kn-keyword=cerebrospinal drainage en-keyword=permissive hypertension kn-keyword=permissive hypertension END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=6 article-no= start-page=695 end-page=703 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=History of Transcatheter Arterial Chemoembolization Predicts the Efficacy of Hepatic Arterial Infusion Chemotherapy in Hepatocellular Carcinoma Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study sought to identify factors that are predictive of a therapeutic response to hepatic arterial infusion chemotherapy (HAIC) by focusing on the number of prior transcatheter arterial chemoembolization (TACE) sessions. To determine the parameters predicting a good response to HAIC, we retrospectively analyzed 170 patients with hepatocellular carcinoma (HCC) who received HAIC regimens comprising low-dose cisplatin combined with 5-fluorouracil (LFP) or cisplatin (CDDP) for the first time. In both the LFP and CDDP regimens, the response rates were significantly lower in patients with three or more prior TACE sessions than in those with two or fewer prior TACE sessions (LFP 57% versus 28%; p=0.01, CDDP 27% versus 6%; p=0.01). Multivariable logistic regression analysis revealed that the number of prior TACE sessions (≥ 3) was significantly associated with non-responder status (odds ratio 4.17, 95% Confidence Interval (CI) 1.76-9.86) in addition to the HAIC regimen. Multivariable analysis using the Cox proportional hazards model revealed that a larger number of prior TACE sessions (≥ 3) was a significant risk factor for survival (hazard ratio 1.60, 95% CI 1.12-2.29) in addition to Child-Pugh class, serum alpha-fetoprotein concentration, and maximum diameter of HCC. HCC patients who receive fewer prior TACE sessions (≤ 2) were found to be better responders to HAIC. en-copyright= kn-copyright= en-aut-name=OnishiHideki en-aut-sei=Onishi en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NousoKazuhiro en-aut-sei=Nouso en-aut-mei=Kazuhiro 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=TakeuchiYasuto en-aut-sei=Takeuchi en-aut-mei=Yasuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical 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= en-keyword=hepatic arterial infusion chemotherapy kn-keyword=hepatic arterial infusion chemotherapy en-keyword=hepatocellular carcinoma kn-keyword=hepatocellular carcinoma en-keyword=refractory kn-keyword=refractory en-keyword=transcatheter arterial chemoembolization kn-keyword=transcatheter arterial chemoembolization END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=5 article-no= start-page=593 end-page=596 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=COVID-19 Vaccine-Associated Lymphadenopathy Mimicking Regrowth of Axillary Lymph Node Metastasis of Lung Adenocarcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=We encountered a woman with re-enlarged axillary lymph nodes during a computed tomography (CT) scan for surveillance of lung adenocarcinoma with axillary lymph node metastasis at the initial diagnosis that had shrunk with standard chemotherapy.

We investigated whether a pediatric patient’s mean arterial pressure (MAP) can affect the rSO2 value during cardiopulmonary bypass (CPB). We retrospectively analyzed the cases of the pediatric patients who underwentcardiac surgery at our hospital (Jan. –Dec. 2019; n=141). At each MAP stage, we constructed line charts through the mean of the rSO2 values corresponding to each MAP and then calculated the correlation coefficients. We next divided the patients into age subgroups (neonates, infants, children) and into cyanotic congenital heart disease (CHD) and acyanotic CHD groups and analyzed these groups in the same way. The analyses of all 141 patients revealed that during CPB the rSO2 value increased with an increase in MAP (r=0.1626). There was a correlation between rSO2 and MAP in the children (r=0.2720) but not in the neonates (r=0.06626) or infants (r=0.05260). Cyanotic CHD or acyanotic CHD did not have a significant effect on the rSO2/MAP correlation. Our analysis demonstrated different patterns of a correlation between MAP and rSO2 in pediatric cardiac surgery patients, depending on age. MAP was positively correlated with rSO2 typically in children but not in neonate or infant patients. en-copyright= kn-copyright= en-aut-name=PanYu en-aut-sei=Pan en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SongQingqing en-aut-sei=Song en-aut-mei=Qingqing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=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 Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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=mean arterial pressure kn-keyword=mean arterial pressure en-keyword=cerebral oxygen saturation kn-keyword=cerebral oxygen saturation END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=5 article-no= start-page=511 end-page=517 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Model-Based Iterative Reconstruction in Low-Dose Paranasal Computed Tomography: A Comparison with Filtered Back Projection and Hybrid Iterative Reconstruction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Iterative reconstruction (IR) improves image quality compared with filtered back projection (FBP). This study investigated the usefulness of model-based IR (forward-projected model-based iterative reconstruction solution [FIRST]) in comparison with FBP and hybrid IR (adaptive iterative dose reduction three-dimensional processing [AIDR 3D]) in low-dose paranasal CT. Twenty-four patients with paranasal sinusitis who underwent standard-dose CT (120 kV) and low-dose CT (100 kV) scanning before and after medical treatment were enrolled. Standard-dose CT scans were reconstructed with FBP (FBP120), and low-dose CT scans with FBP (FBP100), AIDR 3D, and FIRST. The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) in three anatomical structures and effective doses were compared using Mann–Whitney U test. Two radiologists independently evaluated the visibility of 16 anatomical structures, overall image quality, and artifacts. Effective doses in lowdose CT were significantly reduced compared with those in standard-dose CT (0.24 vs 0.43 mSv, p<0.001). FIRST achieved significantly higher SNR (p<0.01, respectively) and CNR (p<0.001, respectively) of evaluated structures and significant improvement in overall image quality (p<0.001), artifacts (p<0.001), and visibility related to muscles (p<0.05) compared to FBP120, FBP100, and AIDR 3D. FIRST allowed radiation-dose reduction, while maintaining objective and subjective image quality in low-dose paranasal CT. en-copyright= kn-copyright= en-aut-name=TomitaHayato en-aut-sei=Tomita en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuramochiKenji en-aut-sei=Kuramochi en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujikawaAtsuko en-aut-sei=Fujikawa en-aut-mei=Atsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IkedaHirotaka en-aut-sei=Ikeda en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KomitaMidori en-aut-sei=Komita en-aut-mei=Midori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KuriharaYoshiko en-aut-sei=Kurihara en-aut-mei=Yoshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KobayashiYasuyuki en-aut-sei=Kobayashi en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MimuraHidefumi en-aut-sei=Mimura en-aut-mei=Hidefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Radiology, St. Marianna University School of Medicine kn-affil= affil-num=2 en-affil=Department of Radiology, St. Marianna University School of Medicine kn-affil= affil-num=3 en-affil=Department of Radiology, St. Marianna University School of Medicine kn-affil= affil-num=4 en-affil=Department of Radiology, Fujita Health University School of Medicine kn-affil= affil-num=5 en-affil=Department of Radiology, St. Marianna University School of Medicine kn-affil= affil-num=6 en-affil=Department of Radiology, Machida Municipal Hospital kn-affil= affil-num=7 en-affil=Department of Advanced Biomedical Imaging Informatics, St. Marianna University School of Medicine kn-affil= affil-num=8 en-affil=Department of Radiology, St. Marianna University School of Medicine kn-affil= en-keyword=paranasal sinuses kn-keyword=paranasal sinuses en-keyword=iterative reconstruction kn-keyword=iterative reconstruction en-keyword=dose reduction kn-keyword=dose reduction en-keyword=low dose kn-keyword=low dose END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=5 article-no= start-page=503 end-page=510 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Viral Sequences Are Repurposed for Controlling Antiviral Responses as Non-Retroviral Endogenous Viral Elements en-subtitle= kn-subtitle= en-abstract= kn-abstract=Eukaryotic genomes contain numerous copies of endogenous viral elements (EVEs), most of which are considered endogenous retrovirus (ERV) sequences. Over the past decade, non-retroviral endogenous viral elements (nrEVEs) derived from ancient RNA viruses have been discovered. Several functions have been proposed for these elements, including antiviral defense. This review summarizes the current understanding of nrEVEs derived from RNA viruses, particularly endogenous bornavirus-like elements (EBLs) and endogenous filovirus-like elements (EFLs). EBLs are one of the most extensively studied nrEVEs. The EBL derived from bornavirus nucleoprotein (EBLN) is thought to function as a non-coding RNA or protein that regulates host gene expression or inhibits virus propagation. Ebolavirus and marburgvirus, which are filoviruses, induce severe hemorrhagic fever in humans and nonhuman primates. Although the ecology of filoviruses remains unclear, bats are believed to be potential reservoirs. Based on the knowledge from EBLs, it is postulated that EFLs in the bat genome help to maintain the balance between filovirus infection and the bat’s defense system, which may partially explain why bats act as potential reservoirs. Further research into the functions of nrEVEs could reveal novel antiviral systems and inspire novel antiviral approaches. en-copyright= kn-copyright= en-aut-name=OgawaHirohito en-aut-sei=Ogawa en-aut-mei=Hirohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HondaTomoyuki en-aut-sei=Honda en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Virology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Virology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=EVE kn-keyword=EVE en-keyword=nrEVE kn-keyword=nrEVE en-keyword=bornavirus kn-keyword=bornavirus en-keyword=filovirus kn-keyword=filovirus en-keyword=antiviral kn-keyword=antiviral END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=5 article-no= start-page=489 end-page=502 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Current Insights into Mesenchymal Signatures in Glioblastoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Glioblastoma (GBM) is a fatal primary malignant brain tumor in adults. Despite decades of research, the prognosis for GBM patients is still disappointing. One major reason for the intense therapeutic resistance of GBM is inter- and intra-tumor heterogeneity. GBM-intrinsic transcriptional profiling has suggested the presence of at least three subtypes of GBM: the proneural, classic, and mesenchymal subtypes. The mesenchymal subtype is the most aggressive, and patients with the mesenchymal subtype of primary and recurrent tumors tend to have a worse prognosis compared with patients with the other subtypes. Furthermore, GBM can shift from other subtypes to the mesenchymal subtype over the course of disease progression or recurrence. This phenotypic transition is driven by diverse tumor-intrinsic molecular mechanisms or microenvironmental factors. Thus, better understanding of the plastic nature of mesenchymal transition in GBM is pivotal to developing new therapeutic strategies. In this review, we provide a comprehensive overview of the current understanding of the elements involved in the mesenchymal transition of GBM and discuss future perspectives. en-copyright= kn-copyright= en-aut-name=MatsumotoYuji en-aut-sei=Matsumoto en-aut-mei=Yuji 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 Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=3 en-affil=Department of Neurosurgery, Hamamatsu University Hospital 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=glioblastoma kn-keyword=glioblastoma en-keyword=mesenchymal subtype kn-keyword=mesenchymal subtype en-keyword=mesenchymal transition kn-keyword=mesenchymal transition en-keyword=heterogeneity kn-keyword=heterogeneity END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=4 article-no= start-page=429 end-page=437 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Association between Preoperative Blood Pressure Elevations and Postoperative Adverse Outcomes after Non-cardiac Surgery: A Single-center Retrospective Observational Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Blood pressure (BP) often rises before surgery. This study investigated whether BP elevation immediately before surgery was associated with adverse outcomes. Medical records of 11,732 patients (average age: 61 years; male: 47.4%) who underwent non-cardiac elective inpatient surgery under general anesthesia at Kagawa University Hospital between January 2011 and June 2019 were reviewed. Differences between the first BP values measured on the day before surgery and the first BP values in the operating room were defined as Δ systolic BP (ΔSBP) and Δ diastolic BP (ΔDBP). The relationships between ΔSBP/ΔDBP and 30-day mortality, 30-day readmission, and over-the-standard length of hospital stay (OSLOS) were assessed. OSLOS was defined as a hospital stay longer than mean+2 standard deviations and was calculated using the Japanese Diagnosis Procedure Combination data. In univariate analysis, the differences in ΔSBP and ΔDBP between the OSLOS and standard LOS groups were both 2 mmHg. In multivariate logistic regression analysis, only ΔDBP was associated with OSLOS. The adjusted odds ratio (95% confidence interval) for the largest quartile was 1.31 (1.02-1.69) (p<0.05). ΔDBP was associated with OSLOS; however, there may be little need to worry about large ΔSBPs and ΔDBPs in clinical practice. en-copyright= kn-copyright= en-aut-name=YamadoriYusuke en-aut-sei=Yamadori en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiraoTomohiro en-aut-sei=Hirao en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Nlandu R.

However, periprosthetic joint infection (PJI) remains an area of concern. We examined the detection rate of bacteria from surgical fields in wound closure, along with the relationship between bacterial detection rate and type of antiseptic, surgery time, and surgeon experience for 500 patients who underwent THA at our department. The mean age at surgery was 64.3 (± 27.3) years. The bacterial detection rate was 4.6%. None of the cases revealed PJI. No significant association between the detection rate and type of antiseptic used or surgery time was observed. However, for patients treated by surgeons with < 10 years of orthopedic experience, a detection rate of 7.3% was found, while a rate of 1.3% was observed for those treated by surgeons with ≥ 10 years of orthopedic experience. This finding indicated that orthopedic experience of less than 10 years was significantly associated with an increased bacterial detection rate (chi-square test, p=0.002). The detection rate was associated with surgeon experience but not with antiseptic type or surgery time. It is possible that intraoperative handling may increase the number of bacteria in surgical fields in wound closure. en-copyright= kn-copyright= en-aut-name=MiyakeYoshiaki en-aut-sei=Miyake en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitaniShigeru en-aut-sei=Mitani en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NambaYoshifumi en-aut-sei=Namba en-aut-mei=Yoshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UmeharaNorifumi en-aut-sei=Umehara en-aut-mei=Norifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawamotoToyohiro en-aut-sei=Kawamoto en-aut-mei=Toyohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FuruichiShuro en-aut-sei=Furuichi en-aut-mei=Shuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Bone and Joint Surgery, Kawasaki Medical School kn-affil= affil-num=2 en-affil=Department of Bone and Joint Surgery, Kawasaki Medical School kn-affil= affil-num=3 en-affil=Department of Bone and Joint Surgery, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of Bone and Joint Surgery, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of Bone and Joint Surgery, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of Bone and Joint Surgery, Kawasaki Medical School kn-affil= en-keyword=total hip arthroplasty kn-keyword=total hip arthroplasty en-keyword=bacterial contamination kn-keyword=bacterial contamination en-keyword=periprosthetic joint infection kn-keyword=periprosthetic joint infection END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=3 article-no= start-page=281 end-page=290 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=Histone Demethylase Jmjd3 Regulates the Osteogenic Differentiation and Cytokine Expressions of Periodontal Ligament Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Periodontal ligament (PDL) cells are critical for the bone remodeling process in periapical lesions since they can differentiate into osteoblasts and secrete osteoclastogenesis-promoting cytokines. Post-translational histone modifications including alterations of the methylation status of H3K27 are involved in cell differentiation and inflammatory reaction. The histone demethylase Jumonji domain-containing 3 (Jmjd3) specifically removes methylation of H3K27. We investigated whether Jmjd3 is involved in the osteogenic differentiation and secretion of PDL cells’ inflammatory factors. Jmjd3 expression in periapical lesions was examined by immunostaining. Using siRNA specific for Jmjd3 or the specific Jmjd3 inhibitor GSK-J4, we determined Jmjd3’s roles in osteogenic differentiation and cytokine production by real-time RT-PCR. The locations of Jmjd3 and NF-κB were analyzed by immunocytochemistry. Compared to healthy PDLs, the periapical lesion samples showed higher Jmjd3 expression. Treatment with GSK-J4 or Jmjd3 siRNA suppressed PDL cells’ osteogenic differentiation by suppressing the expressions of bone-related genes (Runx2, Osterix, and osteocalcin) and mineralization. Jmjd3 knockdown decreased the expressions of cytokines (TNF-α, IL-1β, and IL-6) induced by lipopolysaccharide extracted from Porphyromonas endodontalis (Pe-LPS). Pe-LPS induced the nuclear translocations of Jmjd3 and NF-κB; the latter was inhibited by GSK-J4 treatment. Jmjd3 appears to regulate PDL cells’ osteogenic differentiation and proinflammatory cytokine expressions. en-copyright= kn-copyright= en-aut-name=YuBo en-aut-sei=Yu en-aut-mei=Bo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WangRui en-aut-sei=Wang en-aut-mei=Rui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LuoHuikun en-aut-sei=Luo en-aut-mei=Huikun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YangDi en-aut-sei=Yang en-aut-mei=Di kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WangSimo en-aut-sei=Wang en-aut-mei=Simo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YuYaqiong en-aut-sei=Yu en-aut-mei=Yaqiong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkamuraHirohiko en-aut-sei=Okamura en-aut-mei=Hirohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=QiuLihong en-aut-sei=Qiu en-aut-mei=Lihong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Endodontics, School and Hospital of Stomatology, China Medical University, Liaoning Provincial Key Laboratory of Oral Disease kn-affil= affil-num=2 en-affil=Department of Endodontics, School and Hospital of Stomatology, China Medical University, Liaoning Provincial Key Laboratory of Oral Disease kn-affil= affil-num=3 en-affil=Department of Endodontics, School and Hospital of Stomatology, China Medical University, Liaoning Provincial Key Laboratory of Oral Disease kn-affil= affil-num=4 en-affil=Department of Endodontics, School and Hospital of Stomatology, China Medical University, Liaoning Provincial Key Laboratory of Oral Disease kn-affil= affil-num=5 en-affil=Department of Endodontics, School and Hospital of Stomatology, China Medical University, Liaoning Provincial Key Laboratory of Oral Disease kn-affil= affil-num=6 en-affil=Department of Endodontics, School and Hospital of Stomatology, China Medical University, Liaoning Provincial Key Laboratory of Oral Disease kn-affil= affil-num=7 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Endodontics, School and Hospital of Stomatology, China Medical University, Liaoning Provincial Key Laboratory of Oral Disease kn-affil= en-keyword=periapical lesions kn-keyword=periapical lesions en-keyword=histone demethylase Jmjd3 kn-keyword=histone demethylase Jmjd3 en-keyword=periodontal ligament cell kn-keyword=periodontal ligament cell en-keyword=osteogenic differentiation kn-keyword=osteogenic differentiation en-keyword=proinflammatory cytokines kn-keyword=proinflammatory cytokines END start-ver=1.4 cd-journal=joma no-vol=63 cd-vols= no-issue=5 article-no= start-page=713 end-page=728 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=2022321 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sorghum Ionomics Reveals the Functional SbHMA3a Allele that Limits Excess Cadmium Accumulation in Grains en-subtitle= kn-subtitle= en-abstract= kn-abstract=Understanding uptake and redistribution of essential minerals or sequestering of toxic elements is important for optimized crop production. Although the mechanisms controlling mineral transport have been elucidated in rice and other species, little is understood in sorghum—an important C4 cereal crop. Here, we assessed the genetic factors that govern grain ionome profiles in sorghum using recombinant inbred lines (RILs) derived from a cross between BTx623 and NOG (Takakibi). Pairwise correlation and clustering analysis of 22 elements, measured in sorghum grains harvested under greenhouse conditions, indicated that the parental lines, as well as the RILs, show different ionomes. In particular, BTx623 accumulated significantly higher levels of cadmium (Cd) than NOG, because of differential root-to-shoot translocation factors between the two lines. Quantitative trait locus (QTL) analysis revealed a prominent QTL for grain Cd concentration on chromosome 2. Detailed analysis identified SbHMA3a, encoding a P1B-type ATPase heavy metal transporter, as responsible for low Cd accumulation in grains; the NOG allele encoded a functional HMA3 transporter (SbHMA3a-NOG) whose Cd-transporting activity was confirmed by heterologous expression in yeast. BTx623 possessed a truncated, loss-of-function SbHMA3a allele. The functionality of SbHMA3a in NOG was confirmed by Cd concentrations of F2 grains derived from the reciprocal cross, in which the NOG allele behaved in a dominant manner. We concluded that SbHMA3a-NOG is a Cd transporter that sequesters excess Cd in root tissues, as shown in other HMA3s. Our findings will facilitate the isolation of breeding cultivars with low Cd in grains or in exploiting high-Cd cultivars for phytoremediation. en-copyright= kn-copyright= en-aut-name=WahinyaFiona Wacera en-aut-sei=Wahinya en-aut-mei=Fiona Wacera kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamazakiKiyoshi en-aut-sei=Yamazaki en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=JingZihuan en-aut-sei=Jing en-aut-mei=Zihuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakamiTsuneaki en-aut-sei=Takami en-aut-mei=Tsuneaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KamiyaTakehiro en-aut-sei=Kamiya en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Kajiya-KanegaeHiromi en-aut-sei=Kajiya-Kanegae en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakanashiHideki en-aut-sei=Takanashi en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IwataHiroyoshi en-aut-sei=Iwata en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TsutsumiNobuhiro en-aut-sei=Tsutsumi en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujiwaraToru en-aut-sei=Fujiwara en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University, kn-affil= affil-num=2 en-affil=Graduate School of Agricultural and Life Sciences, The University of Tokyo kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Agricultural and Life Sciences, The University of Tokyo kn-affil= affil-num=6 en-affil=Research Center for Agricultural Information Technology, National Agriculture and Food Research Organization kn-affil= affil-num=7 en-affil=Graduate School of Agricultural and Life Sciences, The University of Tokyo kn-affil= affil-num=8 en-affil=Graduate School of Agricultural and Life Sciences, The University of Tokyo kn-affil= affil-num=9 en-affil=Graduate School of Agricultural and Life Sciences, The University of Tokyo kn-affil= affil-num=10 en-affil=Graduate School of Agricultural and Life Sciences, The University of Tokyo kn-affil= affil-num=11 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=2 article-no= start-page=229 end-page=233 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=A Case of Primary Osteosarcoma of the Mandible That Responded to Preoperative Chemotherapy: p16 as a Potential Prognostic Factor en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a case of mandibular osteosarcoma in a Japanese woman in her 70s who was p16-positive.

The patient had an uneventful postoperative course without pain, and MRI found no recurrence after surgery. A small bone defect remained that might be favorably reconstructed with autologous and artificial bone. Hemilaminectomy allowed us to resect the cauda equina dermoid cyst with minimal invasiveness. Pediatric patients require follow-up as they are more likely to experience spinal deformity or instability after surgery. en-copyright= kn-copyright= en-aut-name=YabunoSatoru en-aut-sei=Yabuno en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=UmakoshiMichiari en-aut-sei=Umakoshi en-aut-mei=Michiari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 ORCID= en-aut-name=KawauchiSatoshi en-aut-sei=Kawauchi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurosurgery, Kagawa Rosai Hospital 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= en-keyword=cauda equina tumor kn-keyword=cauda equina tumor en-keyword=child kn-keyword=child en-keyword=dermoid cyst kn-keyword=dermoid cyst en-keyword=hemilaminectomy kn-keyword=hemilaminectomy en-keyword=spinal tumor kn-keyword=spinal tumor END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=2 article-no= start-page=195 end-page=202 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=Safety and Effectiveness of Perospirone in Comparison to Risperidone for Treatment of Delirium in Patients with Advanced Cancer: A Multicenter Prospective Observational Study in Real-World Psycho-Oncology Settings en-subtitle= kn-subtitle= en-abstract= kn-abstract=The clinical benefit of perospirone for treatment of delirium in patients with advanced cancer is not sufficiently clear. The objective of this study was to compare the safety and effectiveness of perospirone to those of risperidone for the treatment of delirium in patients with advanced cancer. This is a secondary analysis of a multicenter prospective observational study in nine psycho-oncology consultation services in Japan. The study used the Delirium Rating Scale (DRS) Revised-98 to measure effectiveness and the CTCAE (Common Terminology Criteria for Adverse Events) version 4 to assess safety. Data from 16 patients who received perospirone and 53 patients who received risperidone were analyzed. The mean age was 70 years in the perospirone group and 73 years in the risperidone group. Both groups showed a significant decrease in the total score of DRS-R-98 after three days of treatment (perospirone: 11.7 (7.9-15.4) to 7.0 (3.3-10.7), difference −4.7, effect size=0.72, p=0.003; risperidone: 15.5 (13.6-17.4) to 12.2 (10.1-14.2), difference −3.3, effect size=0.55, p=0.00). The risperidone group showed significant improvements in sleep-wake cycle disturbance, orientation, attention, and visuospatial ability. In the perospirone group, there was a significant improvement of sleep-wake cycle disturbance. The median daily dose of perospirone was 4 mg/day. There were fewer episodes of somnolence as an adverse event in the perospirone group. Low-dose perospirone was thus found to be effective for the treatment of delirium in patients with advanced cancer and may be associated with fewer episodes of over-sedation as an adverse event. en-copyright= kn-copyright= en-aut-name=InoueShinichiro en-aut-sei=Inoue en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaIsseki en-aut-sei=Maeda en-aut-mei=Isseki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OgawaAsao en-aut-sei=Ogawa en-aut-mei=Asao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshiuchiKazuhiro en-aut-sei=Yoshiuchi en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TeradaSeishi en-aut-sei=Terada en-aut-mei=Seishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamadaNorihito en-aut-sei=Yamada en-aut-mei=Norihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Neuropsychiatry, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Palliative Care, Senri-Chuo Hospital kn-affil= affil-num=3 en-affil=Department of Psycho-Oncology Service, National Cancer Center Hospital East kn-affil= affil-num=4 en-affil=Department of Stress Sciences and Psychosomatic Medicine, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=5 en-affil=Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=delirium kn-keyword=delirium en-keyword=cancer kn-keyword=cancer en-keyword=perospirone kn-keyword=perospirone en-keyword=risperidone kn-keyword=risperidone END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=2 article-no= start-page=121 end-page=127 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=Grade of Subchondral Insufficiency Fracture of the Knee and the Presence of a Posterior Shiny-Corner Lesion are Correlated with Duration of Medial Meniscus Posterior Root Tear in Women en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bone marrow edema (BME) after meniscus injury and risk factors for subchondral insufficiency fracture of the knee (SIFK) have been reported. However, their association with medial meniscus posterior root tear (MMPRT) remains unknown. We investigated the association of BME volume (BME-V), posterior shinycorner lesion (PSCL), and SIFK with MMPRT to examine the correlations between BME-V and medial meniscus extrusion (MME), PSCL and duration from injury to the time of magnetic resonance imaging (duration), and SIFK and duration. Twenty-nine patients who underwent surgery for MMPRT were included (mean age, 59.2; range, 39-84). The presence of PSCL, femoral BME-V (cm3), and SIFK grade (1-4) were evaluated. Preoperative factors, such as MME (mm) and duration (weeks), were investigated using multivariate linear/ logistic regression analyses. Multivariate linear regression analysis revealed duration as a significant factor for high-grade SIFK (p<0.01). Multivariate logistic regression analysis revealed duration as a significant factor for the presence of PSCL (odds ratio=0.94, p<0.05). A long duration of MMPRT leads to severe MME and highgrade SIFK (3 and 4), often resulting in knee arthroplasty. Early diagnosis of MMPRT and pullout repair can prevent severe MME and high-grade SIFK. en-copyright= kn-copyright= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiranakaTakaaki en-aut-sei=Hiranaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=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=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TetsunagaTomonori en-aut-sei=Tetsunaga en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamaneKentaro en-aut-sei=Yamane en-aut-mei=Kentaro 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=subchondral insufficiency fracture kn-keyword=subchondral insufficiency fracture en-keyword=bone marrow edema kn-keyword=bone marrow edema en-keyword=meniscus extrusion kn-keyword=meniscus extrusion 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.

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=57 end-page=62 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=In Vivo Microwave Ablation of Normal Swine Lung at High-power, Short-duration Settings en-subtitle= kn-subtitle= en-abstract= kn-abstract=To evaluate the volume and heat-sink effects of microwave ablation (MWA) in the ablation zone of the normal swine lung. MWA at 100 W was performed for 1, 2, and 3 min in 7, 5, and 5 lung zones, respectively. We assessed the histopathology in the ablation zones and other outcome measures: namely, length of the longest long and short axes, sphericity, ellipsoid area, and ellipsoid volume. The mean long- and short-axis diameters were 22.0 and 14.1 mm in the 1-min ablation zone, 27.6 and 20.2 mm in the 2-min ablation zone; and 29.2 and 21.2 mm in the 3-min ablation zone, respectively. All measures, except sphericity, were significantly less with 1-min ablation than with either 2- or 3-min ablation. There were no significant differences between the 2- and 3-min ablation zones, but all measures except sphericity were larger with 3-min ablation. Although there were no blood vessels that resulted in a heat-sink effect within the ablation zones, the presence of bronchi nearby in 5 lung ablation zones resulted in reduced ablation size. In high-power, short-duration MWA, the lung ablation volume was affected by ablation time. Some ablations showed that a heat-sink effect by a neighboring bronchus might occur. en-copyright= kn-copyright= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=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=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TojiTomohiro en-aut-sei=Toji en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=TomitaKoji en-aut-sei=Tomita en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KomakiToshiyuki en-aut-sei=Komaki en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UmakoshiNoriyuki en-aut-sei=Umakoshi en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KanazawaSusumu en-aut-sei=Kanazawa en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of 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=Department of Pathology, Okayama University Hospital 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=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=microwave ablation kn-keyword=microwave ablation en-keyword=lung kn-keyword=lung en-keyword=ablation zone kn-keyword=ablation zone en-keyword=heat-sink effect kn-keyword=heat-sink effect en-keyword=swine kn-keyword=swine END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=1 end-page=5 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=Mouse Model for Optogenetic Genome Engineering en-subtitle= kn-subtitle= en-abstract= kn-abstract=Optogenetics, a technology to manipulate biological phenomena thorough light, has attracted much attention in neuroscience. Recently, the Magnet System, a photo-inducible protein dimerization system which can control the intracellular behavior of various biomolecules with high accuracy using light was developed. Furthermore, photoactivation systems for controlling biological phenomena are being developed by combining this technique with genome-editing technology (CRISPR/Cas9 System) or DNA recombination technology (Cre-loxP system). Herein, we review the history of optogenetics and the latest Magnet System technology and introduce our recently developed photoactivatable Cre knock-in mice with temporal-, spatial-, and cell-specific accuracy. en-copyright= kn-copyright= en-aut-name=TakaoTomoka en-aut-sei=Takao en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamadaDaisuke en-aut-sei=Yamada en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakaradaTakeshi en-aut-sei=Takarada en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Regenerative Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Regenerative Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Regenerative Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=optogenetics kn-keyword=optogenetics en-keyword=Cre recombinase kn-keyword=Cre recombinase END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=6 article-no= start-page=699 end-page=704 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Guideline-based Treatment of Glucocorticoid-induced Osteoporosis in Patients with Rheumatoid Arthritis: A Retrospective Study with the AORA Registry en-subtitle= kn-subtitle= en-abstract= kn-abstract=Glucocorticoid-induced osteoporosis (GIOP) is one of the side effects associated with glucocorticoid (GC) therapy. In 2014, the Japanese Society for Bone and Mineral Research (JSBMR) provided new guidelines for the management and treatment of GIOP. The aim of the present study was to clarify the prevalence of patients with rheumatoid arthritis (RA) requiring treatment according to the new guidelines and to identify risk factors associated with lack of treatment in these patients. Patients in the 2018 Akita Orthopedic group on Rheumatoid Arthritis (AORA) database were enrolled. Of 2,234 patients with RA in the database, 683 (30.6%) met the 2014 JSBMR guideline treatment criteria, and 480 (70.3%) had been treated. The untreated group included a larger number of males, younger patients, and patients treated in clinics rather than hospital (p<0.001, p=0.015, and p<0.001, respectively). Multivariate analyses found that male sex, younger age, and clinic-based RA care were significant risk factors associated with lack of treatment (p<0.001, p=0.013, and p<0.001, respectively). Thus, male sex, younger age, and clinic-based care were identified as risk factors en-copyright= kn-copyright= en-aut-name=KawanoTetsuya en-aut-sei=Kawano en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=TsuchieHiroyuki en-aut-sei=Tsuchie en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KashiwaguraTakeshi en-aut-sei=Kashiwagura en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobayashiMoto en-aut-sei=Kobayashi en-aut-mei=Moto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AonumaHiroshi en-aut-sei=Aonuma en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SugimuraYusuke en-aut-sei=Sugimura en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShimadaYoichi en-aut-sei=Shimada en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Akita City Hospital kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Hiraka General Hospital Yokote City kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Ogachi Central Hospital Yuzawa City kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Nakadori General Hospital Akita City kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= en-keyword=glucocorticoid kn-keyword=glucocorticoid en-keyword=glucocorticoid-induced osteoporosis kn-keyword=glucocorticoid-induced osteoporosis en-keyword=rheumatoid arthritis kn-keyword=rheumatoid arthritis en-keyword=osteoporosis kn-keyword=osteoporosis en-keyword=osteopenia kn-keyword=osteopenia END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=5 article-no= start-page=585 end-page=593 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Factors for Acute Kidney Injury Following Total Arch Replacement and Association with Temperature Management During Cardiopulmonary Bypass: A Single-center Retrospective Observational Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Many patients develop acute kidney injury (AKI) after vascular surgery. In this retrospective observational study, we investigated the risk factors for AKI defined using the Kidney Disease Improving Global Outcomes criteria after total arch replacement (TAR). Additionally, we investigated the influence of temperature manage-ment during cardiopulmonary bypass (CPB) on postoperative renal function by propensity score-matched anal-ysis. We retrospectively analyzed 161 consecutive patients who underwent TAR between 2016 and 2019. Postoperative AKI occurred in 48.7% of the patients. In the multivariate analysis, male sex (odds ratio [OR] 3.95, 95% confidence interval [95%CI] 1.56-8.27, p = 0.002), ACE inhibitors/ARB medication (OR 3.19, 95%CI 1.49-6.82, p = 0.003), preoperative chronic kidney disease (OR 2.47, 95%CI 1.17-5.23, p = 0.02), pro-longed CPB time (OR 2.36, 95%CI 1.05-5.34, p = 0.04), and lower body ischemic time during CPB (OR 2.20, 95%CI 1.05-4.46, p = 0.04) were identified as independent risk factors for AKI. Propensity score-matched anal-ysis showed no significant difference in the risk of AKI following TAR between mild hypothermia or normo-thermia and moderate hypothermia (37.2% vs. 41.9%, p = 0.83). In conclusion, modifiable risk factors for AKI included prolonged CPB time and lower body ischemic time. Temperature management during CPB had no clear effect on outcomes. en-copyright= kn-copyright= en-aut-name=OmiyaHiroki en-aut-sei=Omiya en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakatoriMakoto en-aut-sei=Takatori en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YunokiKeiji en-aut-sei=Yunoki en-aut-mei=Keiji 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 Critical Care Medicine, Hiroshima Citizens Hospital kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Critical Care Medicine, Hiroshima Citizens Hospital kn-affil= affil-num=3 en-affil=Department of Cardiovascular Surgery, Hiroshima Citizens Hospital kn-affil= affil-num=4 en-affil=Department of Anesthesiology and Resuscitation, Okayama University Hospital kn-affil= en-keyword=acute kidney injury kn-keyword=acute kidney injury en-keyword=total arch replacement kn-keyword=total arch replacement en-keyword=cardiopulmonary bypass kn-keyword=cardiopulmonary bypass en-keyword=lower body ischemic time kn-keyword=lower body ischemic time END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=4 article-no= start-page=539 end-page=542 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=An Elderly Male with Primary Sjögren’s Syndrome Presenting Pleuritis as the Initial Manifestation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Primary Sjögren’s syndrome (SS) is an autoimmune disease that usually affects the exocrine glands in mid-dle-aged women.

This case highlights the complication of pleuritis among elderly males with primary SS. en-copyright= kn-copyright= en-aut-name=YamamotoYukichika en-aut-sei=Yamamoto en-aut-mei=Yukichika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatsuyamaTakayuki en-aut-sei=Katsuyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 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=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=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Sjögren’s syndrome kn-keyword=Sjögren’s syndrome en-keyword=pleuritis kn-keyword=pleuritis en-keyword=elderly male kn-keyword=elderly male 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=11 cd-vols= no-issue=1 article-no= start-page=11086 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210527 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Leucine-rich alpha-2 glycoprotein as a marker of mucosal healing in inflammatory bowel disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Leucine-rich alpha-2 glycoprotein (LRG) may be a novel serum biomarker for patients with inflammatory bowel disease. The association of LRG with the endoscopic activity and predictability of mucosal healing (MH) was determined and compared with those of C-reactive protein (CRP) and fecal markers (fecal immunochemical test [FIT] and fecal calprotectin [Fcal]) in 166 ulcerative colitis (UC) and 56 Crohn's disease (CD) patients. In UC, LRG was correlated with the endoscopic activity and could predict MH, but the performance was not superior to that of fecal markers (areas under the curve [AUCs] for predicting MH: LRG: 0.61, CRP: 0.59, FIT: 0.75, and Fcal: 0.72). In CD, the performance of LRG was equivalent to that of CRP and Fcal (AUCs for predicting MH: LRG: 0.82, CRP: 0.82, FIT: 0.70, and Fcal: 0.88). LRG was able to discriminate patients with MH from those with endoscopic activity among UC and CD patients with normal CRP levels. LRG was associated with endoscopic activity and could predict MH in both UC and CD patients. It may be particularly useful in CD. en-copyright= kn-copyright= en-aut-name=YasutomiEriko en-aut-sei=Yasutomi en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

Neutrophil-to-Lymphocyte Ratio and Glasgow Prognostic Score are Associated with Clinical Outcome in Patients with Recurrent or Metastatic Head and Neck Squamous Cell Carcinoma 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=279 end-page=287 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=Effects of Gram-negative Rod Blood Stream Infection on Acute GVHD in Allogeneic Hematopoietic Stem Cell Transplantation: A Single-institute Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=A bloodstream infection (BSI) is the most common serious infectious complication of hematopoietic stem cell transplantation (HSCT). BSI promotes an inflammatory state, which exacerbates acute graft-versus-host disease (GVHD). We investigated whether a Gram-negative rod bloodstream infection (GNR-BSI), which develops early after allo-HSCT, affected the onset or exacerbated acute GVHD in 465 patients who underwent allo-HSCT from 1995 through 2015 at a single institution. Eighty-eight patients (19%) developed BSI during the study period. Among the cultures, 50 (57%) were Gram-positive cocci (GPC) and 31 (35%) were GNR. Of the 465 patients, 187 (40%) developed acute GVHD of grade II or higher within the first 100 days post-allogeneic HSCT: 124 (27%) had acute GVHD grade II, 47 (10%) had grade III, and 16 (3%) had grade IV. Multivariate analysis revealed that GNR-BSI was a significant risk factor for grade II-IV acute GVHD (grade II-IV: hazard ratio [HR] 1.75, 95% confidence interval [CI] 1.03-2.97; grade III-IV: HR 2.37, 95% CI 1.03-5.43). These results suggest that GNR-BSI may predict the onset and exacerbation of acute GVHD. en-copyright= kn-copyright= en-aut-name=NishinoharaMasa-aki en-aut-sei=Nishinohara en-aut-mei=Masa-aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 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=4 ORCID= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 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=8 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=9 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= en-keyword=blood stream infection kn-keyword=blood stream infection en-keyword=graft-versus-host disease kn-keyword=graft-versus-host disease en-keyword=gram negative rods kn-keyword=gram negative rods END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=2 article-no= start-page=231 end-page=238 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=Long-term Survival with a Rare Advanced Primary Gastrointestinal Malignant Melanoma Treated with Laparoscopic Surgery/Immune Checkpoint Inhibitor en-subtitle= kn-subtitle= en-abstract= kn-abstract=Targeted therapies for malignant melanoma have improved patients’ prognoses.

PET/CT demonstrated no recurrent lesion for > 3 years. Multidisciplinary therapies (e.g., surgery, chemotherapy, radiotherapy, target therapy, and immune checkpoint antibody-blockade therapy) can successfully treat primary gastrointestinal malignant melanoma. en-copyright= kn-copyright= en-aut-name=EndoMotochika en-aut-sei=Endo en-aut-mei=Motochika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YanoShuya en-aut-sei=Yano en-aut-mei=Shuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AsanoHiroaki en-aut-sei=Asano en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakedaSho en-aut-sei=Takeda en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HamadaYuki en-aut-sei=Hamada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KondoYoshitaka en-aut-sei=Kondo en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KurodaShinji en-aut-sei=Kuroda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShigeyasuKunitoshi en-aut-sei=Shigeyasu en-aut-mei=Kunitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KikuchiSatoru en-aut-sei=Kikuchi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=TeraishiFuminori en-aut-sei=Teraishi en-aut-mei=Fuminori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NishizakiMasahiko en-aut-sei=Nishizaki en-aut-mei=Masahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=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 Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Surgery, Mitoyo general Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Gastroenterological 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=primary gastrointestinal melanoma kn-keyword=primary gastrointestinal melanoma en-keyword=laparoscopic surgery kn-keyword=laparoscopic surgery en-keyword=immune checkpoint antibody-blockade inhibitor kn-keyword=immune checkpoint antibody-blockade inhibitor 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).

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.

When patients with APL experience a synchronous solid organ tumor, the tumor’s treatment must also be done properly. Differentiation-inducing therapy using arsenic trioxide (ATO) has less hematological toxicity compared to cytotoxic chemotherapy and might be preferable for untreated APL patients with a synchronous solid organ tumor. Here we describe the first successful case of untreated APL and synchronous endometrial cancer (in an adult Japanese woman) treated with ATO consolidation therapy and the subsequent surgery and chemotherapy for endometrial cancer. en-copyright= kn-copyright= en-aut-name=SugiuraHiroyuki en-aut-sei=Sugiura en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimoriHisakazu en-aut-sei=Nishimori en-aut-mei=Hisakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuokaHirofumi en-aut-sei=Matsuoka en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakamuraKeiichiro en-aut-sei=Nakamura en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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=7 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= 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 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 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= en-keyword=acute promyelocytic leukemia kn-keyword=acute promyelocytic leukemia en-keyword=endometrial cancer kn-keyword=endometrial cancer en-keyword=arsenic trioxide kn-keyword=arsenic trioxide en-keyword=synchronous multiple primary malignant tumor kn-keyword=synchronous multiple primary malignant tumor en-keyword=chemotherapy kn-keyword=chemotherapy END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=2 article-no= start-page=147 end-page=152 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Knee Flexion-induced Translation of Pullout Sutures Used in the Repair of Medial Meniscus Posterior Root Tears en-subtitle= kn-subtitle= en-abstract= kn-abstract=Medial meniscus posterior root tears (MMPRTs) have recently attracted considerable interest in orthopedics. To date, no in vivo human study has investigated suture translation changes in repaired MMPRTs with different degrees of knee flexion. This study examined suture translation at various degrees of knee flexion in 30 patients undergoing medial meniscus posterior root repair using the modified Mason-Allen suture technique between August 2016 and September 2017. Intraoperatively, sutures were provisionally fixed to an isometric positioner at the tibial site of the desired meniscal attachment, and the suture translation was measured at 0°, 30°, 60°, and 90° of knee flexion. The results showed significant increases in mean suture translation at the knee flexion positions from 0° to 30°, 30° to 60°, and 60° to 90° (p<0.01 for all). Our findings indicate that surgeons should carefully assess the degree of knee flexion at the moment when the meniscus is refixed by surgical sutures. en-copyright= kn-copyright= en-aut-name=XueHaowei en-aut-sei=Xue en-aut-mei=Haowei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiranakaTakaaki en-aut-sei=Hiranaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KintakaKeisuke en-aut-sei=Kintaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiiMasataka en-aut-sei=Fujii en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ZhangXiming en-aut-sei=Zhang en-aut-mei=Ximing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=medial meniscus kn-keyword=medial meniscus en-keyword=posterior root tear kn-keyword=posterior root tear en-keyword=suture translation kn-keyword=suture translation en-keyword=knee flexion kn-keyword=knee flexion en-keyword=arthroscopic repair kn-keyword=arthroscopic repair END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=4 article-no= start-page=336 end-page=342 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200129 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The presence of chronic diseases contributes to the occurrence risk factors for gynecological cancers in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of the present study was to determine whether chronic diseases (CD), such as hypertension, diabetes mellitus, dyslipidemia, heart diseases and cerebrovascular diseases, are occurrence risk factors and affect the survival of patients with gynecological cancers (GC). The correlations between CD and the characteristics and survival of 1,590 GC patients [685 with cervical cancer (CC), 613 with endometrial cancer (EM) and 292 with ovarian cancer (OV)] were investigated in the present study. Of the CD patients, 189 had CC (27.6%), 265 had EM (43.2%) and 72 had OV (24.7%). The incidence of CD increased with age in GC patients. The number of CD patients aged ≥70 years, was 8.6‑fold higher in the CC group, 3.0‑fold higher in the EM group, and 9.6‑fold higher in the OV group compared with those aged <50 years. CD and excess body weight were associated with GC regardless of patient age. However, there was no correlation between CD and survival at any age in GC patients. These findings indicate that CD contribute to >24% of the occurrence risk factors in GC patients in Japan. en-copyright= kn-copyright= en-aut-name=OkamotoKazuhiro en-aut-sei=Okamoto en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamuraKeiichiro en-aut-sei=Nakamura en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuokaHirofumi en-aut-sei=Matsuoka en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsubaraYuko en-aut-sei=Matsubara en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HaragaJunko en-aut-sei=Haraga en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OgawaChikako en-aut-sei=Ogawa en-aut-mei=Chikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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= affil-num=6 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=gynecological cancer kn-keyword=gynecological cancer en-keyword=chronic diseases kn-keyword=chronic diseases en-keyword=occurrence risk factors kn-keyword=occurrence risk factors END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=6 article-no= start-page=531 end-page=535 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=Soft Tissue Myoepithelioma of the Shoulder en-subtitle= kn-subtitle= en-abstract= kn-abstract=Soft tissue myoepitheliomas are often misdiagnosed due to their rarity.

To better understand the relation of Cd binding to S and Cd isotope fractionation in soils and plants, we combined isotope and XAS speciation analyses in soil-rice systems that were rich in Cd and S. The systems included distinct water management (flooded vs. non-flooded) and rice accessions with (excluder) and without (non-excluder) functional membrane transporter OsHMA3 that transports Cd into root vacuoles. Initially, 13% of Cd in the soil was bound to S. Through soil flooding, the proportion of Cd bound to S increased to 100%. Soil flooding enriched the rice plants towards heavy isotopes (δ114/110Cd = −0.37 to −0.39%) compared to the plants that grew on non-flooded soils (δ114/110Cd = −0.45 to −0.56%) suggesting that preferentially light Cd isotopes precipitated into Cd sulfides. Isotope compositions in CaCl2 root extracts indicated that the root surface contributed to the isotope shift between soil and plant during soil flooding. In rice roots, Cd was fully bound to S in all treatments. The roots in the excluder rice strongly retained Cd and its lights isotopes while heavy isotopes were transported to the shoots (Δ114/110Cdshoot-root 0.16–0.19‰). The non-excluder rice accumulated Cd in shoots and the apparent difference in isotope composition between roots and shoots was smaller than that of the excluder rice (Δ114/110Cdshoot-root −0.02 to 0.08‰). We ascribe the retention of light Cd isotopes in the roots of the excluder rice to the membrane transport of Cd by OsHMA3 and/or chelating Cd–S complexes in the vacuole. Cd–S was the major binding form in flooded soils and rice roots and partly contributed to the immobilization of Cd and its light isotopes in soil-rice systems. en-copyright= kn-copyright= en-aut-name=WiggenhauserMatthias en-aut-sei=Wiggenhauser en-aut-mei=Matthias kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AucourAnne-Marie en-aut-sei=Aucour en-aut-mei=Anne-Marie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BureauSarah en-aut-sei=Bureau en-aut-mei=Sarah kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=CampilloSylvain en-aut-sei=Campillo en-aut-mei=Sylvain kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TeloukPhilippe en-aut-sei=Telouk en-aut-mei=Philippe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=RomaniMarco en-aut-sei=Romani en-aut-mei=Marco kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MaJian Feng en-aut-sei=Ma en-aut-mei=Jian Feng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=LandrotGautier en-aut-sei=Landrot en-aut-mei=Gautier kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SarretGéraldine en-aut-sei=Sarret en-aut-mei=Géraldine kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Univ.

Anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitors (TKIs) are effective for patients with the echinoderm microtubule-associated protein-like 4-ALK fusion gene. Several ALK-TKIs have been established: the first-generation ALK-TKI, crizotinib; second-generation ALK-TKIs, alectinib and ceritinib; and third-generation ALK-TKI, lorlatinib. Some ALK-TKIs are effective for tumors that are resistant to other ALK-TKIs; however, as is known in epidermal growth factor receptormutant lung cancer, tumor resistance is inevitable. ALK-positive NSCLCs acquire resistance via various mechanisms, making it a heterogeneous disease. Therefore, it is necessary to develop next-generation treatment strategies, such as the use of next-generation ALK-TKIs for secondary mutations, or combination therapies with ALK-TKIs and other TKIs. In this review, we summarize the development and use of ALK-TKIs, prior pivotal clinical trials, and resistance mechanisms. en-copyright= kn-copyright= en-aut-name=MakimotoGo en-aut-sei=Makimoto en-aut-mei=Go kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhashiKadoaki en-aut-sei=Ohashi en-aut-mei=Kadoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=KiuraKatsuyuki en-aut-sei=Kiura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Respiratory Medicine, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=2 en-affil=Department of 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 Respiratory Medicine, Okayama University Hospital kn-affil= en-keyword=lung cancer kn-keyword=lung cancer en-keyword=anaplastic lymphoma kinase kn-keyword=anaplastic lymphoma kinase en-keyword=tyrosine kinase inhibitors kn-keyword=tyrosine kinase inhibitors en-keyword=resistance mechanism kn-keyword=resistance mechanism END start-ver=1.4 cd-journal=joma no-vol=117 cd-vols= no-issue=10 article-no= start-page=101103 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200909 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Super-chiral vibrational spectroscopy with metasurfaces for high-sensitive identification of alanine enantiomers en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chiral nature of an enantiomer can be characterized by circular dichroism (CD) spectroscopy, but such a technique usually suffers from weak signal even with a sophisticated optical instrument. Recent demonstrations of plasmonic metasurfaces showed that chiroptical interaction of molecules can be engineered, thereby greatly simplifying a measurement system with high sensing capability. Here, by exploiting super-chiral field in a metasurface, we experimentally demonstrate high-sensitive vibrational CD spectroscopy of alanine enantiomers, the smallest chiral amino acid. Under linearly polarized excitation, the metasurface consisting of an array of staggered Au nano-rods selectively produces the left- and right-handed super-chiral fields at 1600 cm−1, which spectrally overlaps with the functional group vibrations of alanine. In the Fourier-transform infrared spectrometer measurements, the mirror symmetric CD spectra of D- and L-alanine are clearly observed depending on the handedness of the metasurface, realizing the reliable identification of small chiral molecules. The corresponding numerical simulations reveal the underlying resonant chiroptical interaction of plasmonic modes of the metasurface and vibrational modes of alanine. Our approach demonstrates a high-sensitive vibrational CD spectroscopic technique, opening up a reliable chiral sensing platform for advanced infrared inspection technologies. en-copyright= kn-copyright= en-aut-name=IidaTakumi en-aut-sei=Iida en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshikawaAtsushi en-aut-sei=Ishikawa en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaTakuo en-aut-sei=Tanaka en-aut-mei=Takuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MuranakaAtsuya en-aut-sei=Muranaka en-aut-mei=Atsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UchiyamaMasanobu en-aut-sei=Uchiyama en-aut-mei=Masanobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HayashiYasuhiko en-aut-sei=Hayashi en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=Metamaterials Laboratory, RIKEN Cluster for Pioneering Research kn-affil= affil-num=4 en-affil=Advanced Elements Chemistry Laboratory, RIKEN Cluster for Pioneering Research kn-affil= affil-num=5 en-affil=Advanced Elements Chemistry Laboratory, RIKEN Cluster for Pioneering Research kn-affil= affil-num=6 en-affil=Department of Electrical and Electronic Engineering, Okayama University kn-affil= affil-num=7 en-affil=Department of Electrical and Electronic Engineering, Okayama University kn-affil= 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. In addition, Ki-67 was revealed to be a useful parameter to predict recurrence in SFT/HPC patients. en-copyright= kn-copyright= en-aut-name=YamamotoYumiko en-aut-sei=Yamamoto en-aut-mei=Yumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayashiYoshihiro en-aut-sei=Hayashi en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MurakamiIchiro en-aut-sei=Murakami en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Diagnostic Pathology, Kochi University kn-affil= affil-num=2 en-affil=Department of Equipment of Support Planning Office, Kochi University kn-affil= affil-num=3 en-affil=Department of Diagnostic Pathology, Kochi University kn-affil= en-keyword=solitary fibrous tumor kn-keyword=solitary fibrous tumor en-keyword=hemangiopericytoma kn-keyword=hemangiopericytoma en-keyword=Ki-67 kn-keyword=Ki-67 en-keyword=NAB2-STAT6 kn-keyword=NAB2-STAT6 en-keyword=WHO classification kn-keyword=WHO classification en-keyword=WHO grading criteria kn-keyword=WHO grading criteria en-keyword=Marseille Grading System kn-keyword=Marseille Grading System END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=4 article-no= start-page=275 end-page=283 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=Decreased Serum Antioxidant Marker is Predictive of Early Recurrence in the Same Segment after Radical Ablation for Hepatocellular Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) is a promising method for controlling tumors, although it does not entirely eliminate recurrence. Oxidative stress is associated with the progression of hepatocarcinogenesis, while also acting as an anticancer response. The objective of the present study was to investigate the factors influencing post-RFA outcomes. We recruited 235 newly diagnosed HCC patients who received RFA for single tumors. The patients with recurrence were sub-grouped into early and segmental recurrence groups. The characteristics of the sub-grouped patients were evaluated, including by measuring oxidative stress marker reactive oxygen metabolites and antioxidant marker OXY-adsorbent tests. The factors associated with poor survival were a high Child-Pugh score and early recurrence within 2 years in the same segment. The patients who experienced recurrence within 2 years in the same segment showed a larger tumor diameter than did others. According to a multivariate analysis, the OXY values were also significantly low in these patients. In conclusion, maintaining the antioxidant reservoir function with a high OXY value might be necessary to prevent early recurrence within the RFA-treated segment. en-copyright= kn-copyright= en-aut-name=MuroTaiko en-aut-sei=Muro en-aut-mei=Taiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamuraShinichiro en-aut-sei=Nakamura en-aut-mei=Shinichiro 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=OnishiHideki en-aut-sei=Onishi en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 ORCID= en-aut-name=UchidaDaisuke en-aut-sei=Uchida en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 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=10 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=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 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= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=oxidative stress kn-keyword=oxidative stress en-keyword=hepatocellular carcinoma kn-keyword=hepatocellular carcinoma en-keyword=recurrence, kn-keyword=recurrence, en-keyword=radiofrequency ablation kn-keyword=radiofrequency ablation END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=4 article-no= start-page=265 end-page=274 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=Factors Predicting a Favorable Disease Course Without Anti-TNF Therapy in Crohn’s Disease Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Determining factors that predict a favorable disease course without anti-tumor necrosis factor (TNF) agents would help establish a more cost-effective strategy for Crohn’s disease (CD). A retrospective chart review was performed for CD patients with disease durations > 10 years who had not received anti-TNF agents as first-line therapy. Patients were divided into 2 groups: those who received neither anti-TNF agents nor bowel resection (G1), and those who had received an anti-TNF agent and/or bowel resection (G2). The patient backgrounds, therapies and clinical courses were compared between the groups. A total of 62 CD patients met the inclusion criteria (males: 71%; median duration of follow-up: 19 years). Six patients were included in G1; they were significantly less likely to have upper gastrointestinal lesions than G2 (p=0.007). A multivariate analysis revealed that the significant factors for avoidance of bowel resection without anti-TNF treatment were non-stricturing and non-penetrating behaviors, and absence of upper gastrointestinal lesions at the diagnosis (hazard ratios 0.41 and 0.52; p=0.004 and 0.04, respectively). In consideration of the long treatment course of CD, patients with non-stricturing and non-penetrating behaviors and no upper gastrointestinal lesions should not be treated with anti-TNF agents as first-line therapy. en-copyright= kn-copyright= en-aut-name=InokuchiToshihiro en-aut-sei=Inokuchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasutomiEriko en-aut-sei=Yasutomi en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkaShohei en-aut-sei=Oka en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamasakiYasushi en-aut-sei=Yamasaki en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KinugasaHideaki en-aut-sei=Kinugasa en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakaharMasahiro en-aut-sei=Takahar en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HaradaKeita en-aut-sei=Harada en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KatoJun en-aut-sei=Kato 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 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= affil-num=11 en-affil=bDepartment of Gastroenterology, Mitsui Memorial Hospital kn-affil= en-keyword=Crohn’s disease kn-keyword=Crohn’s disease en-keyword=anti-TNF agent kn-keyword=anti-TNF agent en-keyword=upper gastrointestinal lesion kn-keyword=upper gastrointestinal lesion en-keyword=bamboo joint-like appearance kn-keyword=bamboo joint-like appearance END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=10 article-no= start-page=2717 end-page=2725 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The tonoplast-localized transporter OsHMA3 plays an important role in maintaining Zn homeostasis in rice en-subtitle= kn-subtitle= en-abstract= kn-abstract=In order to respond to fluctuating zinc (Zn) in the environment, plants must have a system to control Zn homeostasis. However, how plants maintain an appropriate level of Zn during their growth and development is still poorly understood. In this study, we found that OsHMA3, a tonoplast-localized transporter for Zn/Cd, plays an important role in Zn homeostasis in rice. Accessions with the functional allele of OsHMA3 showed greater tolerance to high Zn than those with the non-functional allele based on root elongation test. A 67Zn-labeling experiment showed that accessions with loss of function of OsHMA3 had lower Zn accumulation in the roots but similar concentrations in the shoots compared with functional OsHMA3 accessions. When exposed to Zn-free growing medium, the concentration in the root cell sap was rapidly decreased in accessions with functional OsHMA3, but less dramatic changes were observed in non-functional accessions. A mobility experiment showed that more Zn in the roots was translocated to the shoots in accessions with functional OsHMA3. Higher expression levels of OsZIP4, OsZIP5, OsZIP8, and OsZIP10 were found in the roots of accessions with functional OsHMA3 in response to Zn deficiency. Taken together, our results indicate that OsHMA3 plays an important role in rice roots in both Zn detoxification and storage by sequestration into the vacuoles, depending on Zn concentration in the environment. en-copyright= kn-copyright= en-aut-name=CaiHongmei en-aut-sei=Cai en-aut-mei=Hongmei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HuangSheng en-aut-sei=Huang en-aut-mei=Sheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=CheJing en-aut-sei=Che en-aut-mei=Jing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamajiNaoki en-aut-sei=Yamaji en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaJian Feng en-aut-sei=Ma en-aut-mei=Jian Feng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=OsHMA3 kn-keyword=OsHMA3 en-keyword=vacuolar sequestration kn-keyword=vacuolar sequestration en-keyword=ZIP transporter kn-keyword=ZIP transporter en-keyword=Zn distribution kn-keyword=Zn distribution en-keyword= Zn root-to-shoot mobility kn-keyword= Zn root-to-shoot mobility en-keyword=Zn tolerance kn-keyword=Zn tolerance END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=3 article-no= start-page=237 end-page=243 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=Serum REIC/Dickkopf-3 Protein Level Predicts Disease-Free Survival in Patients with Hepatocellular Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=The physiological role of the reduced expression of immortalized cells (REIC)/Dickkopf-3 (Dkk-3) protein in patients with hepatocellular carcinoma (HCC) remains unclear. In this study, we evaluated the effect of the REIC/Dkk-3 protein on HCC cell proliferation and assessed the relationship between the serum REIC/Dkk-3 protein level and the prognosis in patients with HCC. We evaluated the REIC/Dkk-3 protein-induced anticancer effects on Huh7 and Hep3B cells (HCC cell lines) in the presence of peripheral blood mononuclear cells (PBMCs), and found that combination treatment with REIC/Dkk-3 protein and PBMCs reduced the proliferation of HCC cells (Hep3B: 82.0%±16.3%; Huh7: 72.6%±9.1%). We also studied 194 HCC patients who underwent primary liver resection or primary radiofrequency ablation from 2008 to 2017. Serum REIC/Dkk-3 protein levels were measured by an enzyme-linked immunosorbent assay and compared to the prognostic data. The 3-year disease-free survival of the REIC/Dkk-3 high group was significantly higher than that in the REIC/Dkk-3 low group. In conclusion, this is the first study investigating the relationship between HCC patient survival and serum REIC/Dkk-3 protein levels in a large population. Based on the results, the serum REIC/Dkk-3 protein level should be considered a new prognostic marker for patients with HCC. en-copyright= kn-copyright= en-aut-name=OyamaAtsushi en-aut-sei=Oyama en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UchidaDaisuke en-aut-sei=Uchida en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=SawaharaHiroaki en-aut-sei=Sawahara en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatoRyo en-aut-sei=Kato en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HoriguchiShigeru en-aut-sei=Horiguchi en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University 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= en-keyword=enzyme-linked immunosorbent assay kn-keyword=enzyme-linked immunosorbent assay en-keyword=liver resection kn-keyword=liver resection en-keyword=primary radiofrequency ablation kn-keyword=primary radiofrequency ablation en-keyword=Huh7 kn-keyword=Huh7 en-keyword=Hep3B kn-keyword=Hep3B 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=50 cd-vols= no-issue=2 article-no= start-page=184 end-page=191 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190618 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparison of the clinical characteristics of TAFRO syndrome and idiopathic multicentric Castleman disease in general internal medicine: a 6‐year retrospective study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Although thrombocytopenia, anasarca, fever, reticulin fibrosis and organomegaly (TAFRO) syndrome was first described as a variant of idiopathic multicentric Castleman disease (CD), patients with TAFRO syndrome demonstrate more aggressive clinical features. Because these patients may present with fever of unknown origin, general physicians need to recognise its characteristic laboratory data and clinical features during hospitalisation.
Aims
to describe the features, symptoms and characteristics of TAFRO syndrome and to compare them to those of idiopathic CD.
Methods
This was a retrospective study of patients with histopathologically confirmed TAFRO syndrome and idiopathic multicentric CD who were diagnosed and managed between April 2012 and June 2018 in a Japanese university hospital's General Medicine Department.
Results
We found that the hospitalisations were significantly longer among patients with TAFRO syndrome compared to those with idiopathic CD (median: 87 days; range: 34–236 days vs median: 30 days; range: 13–59 days; P < 0.01). Patients with TAFRO syndrome were more likely to present with fever, abdominal pain and elevated inflammatory markers and be misdiagnosed with an infectious disease during the first hospital visit. Approximately 40% of patients with TAFRO syndrome had no radiographically enlarged lymph nodes.
Conclusions
TAFRO syndrome may present as an infectious disease with an aggressive clinical course. Our study highlights the importance of giving significance to chief complaints and laboratory data. Physicians need to recognise the clinical and laboratory features of this disease to avoid missing this potentially fatal disorder. en-copyright= kn-copyright= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Hanayama Yoshihisa 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=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KondoEisei en-aut-sei=Kondo en-aut-mei=Eisei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Hematology, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=TAFRO syndrome kn-keyword=TAFRO syndrome en-keyword=Castleman disease kn-keyword=Castleman disease en-keyword=chief complaint kn-keyword=chief complaint en-keyword=procalcitonin kn-keyword=procalcitonin en-keyword=immunoglobulin kn-keyword=immunoglobulin END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=2 article-no= start-page=123 end-page=128 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=The Diagnostic Capacity of Pre-treatment 18F-FDG PET/CT for Predicting the Extranodular Spread of Lymph Node Metastases in Patients with Oral Squamous Cell Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract= The aim of this study was to evaluate the ability of pretreatment 90-min 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) to predict the extranodular spread of lymph node metastases in oral squamous cell carcinoma. We retrospectively reviewed the cases of 56 patients who underwent pretreatment 18F-FDG PET/CT and surgery with neck dissection. Maximum standardized uptake value, metabolic tumor volume, and total lesion glycolysis were measured for the 56 primary sites and maximum standardized uptake value was measured for 115 lymph node levels. Extranodular spread was present at 9 lymph node levels in 7 patients. Significant differences were found in metabolic tumor volume and total lesion glycolysis of the primary site, and in lymph node maximum standardized uptake value, between patients with and without extranodular spread (p<0.05). Combining primary site total lesion glycolysis and lymph node maximum standardized uptake volume at their respective optimal cutoffs, the sensitivity, specificity, and accuracy for predicting extranodular spread were 89%, 92%, and 92%, respectively. Pretreatment 18F-FDG PET/CT is useful for predicting extranodular spread in patients with oral squamous cell carcinoma. The combined use of primary site total lesion glycolysis and lymph node maximum standardized uptake value showed greater predictive value than either predictor singly. en-copyright= kn-copyright= en-aut-name=FukuharaRyuichiro en-aut-sei=Fukuhara en-aut-mei=Ryuichiro 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=FukumaShogo en-aut-sei=Fukuma en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MarunakaHidenori en-aut-sei=Marunaka en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AriokaTadashi en-aut-sei=Arioka en-aut-mei=Tadashi 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=KajiMitsumasa en-aut-sei=Kaji en-aut-mei=Mitsumasa 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 Diagnostic Imaging Center, Okayama university Hospital kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= affil-num=4 en-affil=Department of Radiology, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= affil-num=6 en-affil=Department of Pathology, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= affil-num=7 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= affil-num=8 en-affil=Department of Radiology, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= affil-num=9 en-affil=Department of Radiology, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= affil-num=10 en-affil=Department of Radiology, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= affil-num=11 en-affil=Department of Radiology, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= en-keyword=18F-fluorodeoxyglucose positron emission tomography/computed tomography kn-keyword=18F-fluorodeoxyglucose positron emission tomography/computed tomography en-keyword=extranodular spread kn-keyword=extranodular spread en-keyword=metastasis kn-keyword=metastasis en-keyword=oral squamous cell carcinoma kn-keyword=oral squamous cell carcinoma END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=2 article-no= start-page=103 end-page=108 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=Effects of Switching from Treatment with Amlodipine and Atorvastatin Using Two Pills to an Equal Dose of Single-Pill Therapy in Japanese Outpatients en-subtitle= kn-subtitle= en-abstract= kn-abstract= This study examined whether switching from amlodipine and atorvastatin treatment using two pills to an equal dose of single-pill therapy is useful in Japanese outpatients. We retrospectively reviewed data obtained from 94 outpatients for whom treatment with two pills, namely amlodipine and atorvastatin, was switched to an equal dose of single-pill therapy in 11 hospitals. The criterion for enrollment in this study was that patients had switched their medication without changing other anti-hypertensive or anti-cholesterol drugs. Neither systolic nor diastolic blood pressure changed significantly after switching to an equal dose of single-pill therapy, whereas low-density lipoprotein (LDL) cholesterol levels significantly decreased after the medication was switched from 94±24 mg/dl to 89±17 mg/dl (p=0.015). A switch from medication with two separate pills of amlodipine and atorvastatin to an equal dose of single-pill therapy resulted in an overall decrease in LDL cholesterol. The results indicated that the switch to single-pill therapy might be a useful treatment. en-copyright= kn-copyright= en-aut-name=KawadaYasumasa en-aut-sei=Kawada en-aut-mei=Yasumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuboToru en-aut-sei=Kubo en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BabaYuichi en-aut-sei=Baba en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HirotaTakayoshi en-aut-sei=Hirota en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TaniokaKatsutoshi en-aut-sei=Tanioka en-aut-mei=Katsutoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamasakiNaohito en-aut-sei=Yamasaki en-aut-mei=Naohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KitaokaHiroaki en-aut-sei=Kitaoka en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Cardiology and Geriatrics, Kochi Medical School, Kochi University kn-affil= affil-num=2 en-affil=Department of Cardiology and Geriatrics, Kochi Medical School, Kochi University kn-affil= affil-num=3 en-affil=Department of Cardiology and Geriatrics, Kochi Medical School, Kochi University kn-affil= affil-num=4 en-affil=Department of Cardiology and Geriatrics, Kochi Medical School, Kochi University kn-affil= affil-num=5 en-affil=Department of Cardiology and Geriatrics, Kochi Medical School, Kochi University kn-affil= affil-num=6 en-affil=Department of Cardiology and Geriatrics, Kochi Medical School, Kochi University kn-affil= affil-num=7 en-affil=Department of Cardiology and Geriatrics, Kochi Medical School, Kochi University kn-affil= en-keyword=hypertension kn-keyword=hypertension en-keyword=dyslipidemia kn-keyword=dyslipidemia en-keyword=single-pill therapy kn-keyword=single-pill therapy END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=2 article-no= start-page=95 end-page=101 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=The Efficacy of Software to Help Patients Understand Drug for Adjuvant Treatment for Breast Cancer: A Pilot Randomized Controlled Trial en-subtitle= kn-subtitle= en-abstract= kn-abstract= We assessed the usefulness of ChemoCalc, a software package for calculating drug costs, in helping patients understand these costs. We randomly assigned, in a 1 : 1 ratio, 20 women who had undergone surgery for early breast cancer to a group that discussed adjuvant treatment with their physicians using the ChemoCalc software (ChemoCalc group) or a group that discussed adjuvant treatment without ChemoCalc (Usual Explanation group). The participants completed a five-grade evaluation questionnaire after these discussions. The primary endpoint was the intergroup comparison of the questionnaire scores regarding participants’ understanding of their treatment-associated drug costs. Median age was not significantly different between the ChemoCalc group and Usual Explanation group (57 vs. 50, respectively; p=0.27). Patients in the ChemoCalc group had a significantly higher perceived level of understanding of the drug cost than those in the Usual Explanation group (5 [4-5] vs. 2.5 [1-5], respectively; p=0.002). Scores related to the patients’ perception that understanding drug costs is an important part of breast cancer treatment were also higher in the ChemoCalc group than the Usual Explanation group (5 [2-5] vs. 3 [1-5], respectively; p=0.049). ChemoCalc was found to be useful for understanding drug costs. en-copyright= kn-copyright= en-aut-name=KubaSayaka en-aut-sei=Kuba en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamanouchiKosho en-aut-sei=Yamanouchi en-aut-mei=Kosho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoritaMichi en-aut-sei=Morita en-aut-mei=Michi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakimuraChika en-aut-sei=Sakimura en-aut-mei=Chika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=InamasuEiko en-aut-sei=Inamasu en-aut-mei=Eiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HatachiToshiko en-aut-sei=Hatachi en-aut-mei=Toshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OtsuboRyota en-aut-sei=Otsubo en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsumotoMegumi en-aut-sei=Matsumoto en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YanoHiroshi en-aut-sei=Yano en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MiyamotoJunya en-aut-sei=Miyamoto en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SatoShuntaro en-aut-sei=Sato en-aut-mei=Shuntaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NakagawaHiroo en-aut-sei=Nakagawa en-aut-mei=Hiroo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=KanetakaKengo en-aut-sei=Kanetaka en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=TakatsukiMitsuhisa en-aut-sei=Takatsuki en-aut-mei=Mitsuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=NagayasuTakeshi en-aut-sei=Nagayasu en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=EguchiSusumu en-aut-sei=Eguchi en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Surgery, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=2 en-affil=Department of Surgery, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=3 en-affil=Department of Surgery, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=4 en-affil=Department of Surgery, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=5 en-affil=Department of Surgical Oncology, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=6 en-affil=Department of Surgical Oncology, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=7 en-affil=Department of Surgical Oncology, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=8 en-affil=Department of Surgical Oncology, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=9 en-affil=Department of Surgical Oncology, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=10 en-affil=Department of Clinical Research Center, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=11 en-affil=Department of Clinical Research Center, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=12 en-affil=Department of Pharmacy, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=13 en-affil=Department of Surgery, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=14 en-affil=Department of Surgery, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=15 en-affil=Department of Surgical Oncology, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=16 en-affil=Department of Surgery, Nagasaki University Graduate School of Biomedical Science kn-affil= en-keyword=breast cancer kn-keyword=breast cancer en-keyword=drug costs kn-keyword=drug costs en-keyword=ChemoCalc kn-keyword=ChemoCalc END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=1 article-no= start-page=41 end-page=48 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=The Prevalence and Characteristics of Older Japanese Adults with Polypharmacy, Based on Regionally Representative Health Insurance Claims Data en-subtitle= kn-subtitle= en-abstract= kn-abstract= We aimed to clarify the prevalence of polypharmacy among elderly individuals in Japan. 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=73 cd-vols= no-issue=6 article-no= start-page=533 end-page=536 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=Reconstruction of Complete Peroneus Longus and Brevis Tendon Ruptures Using a Semitendinosus and Gracilis Tendon Graft en-subtitle= kn-subtitle= en-abstract= kn-abstract= The patient was a 40-year-old female who had been treated at our hospital for left peroneal tendonitis due to an ankle sprain 2 years earlier.

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=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=495 end-page=501 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=Transtibial Pullout Repair Reduces Posterior Extrusion of the Medial Meniscus en-subtitle= kn-subtitle= en-abstract= kn-abstract= Medial meniscus posterior root tear causes rapid knee cartilage degradation by inducing posteromedial displacement of the medial meniscus. We evaluated medial meniscus posterior extrusion before and after pullout repair for medial meniscus posterior root tear using magnetic resonance images. Twenty-eight patients with symptomatic medial meniscus posterior root tear were included. The inclusion criteria were: acute (< 3 months) or chronic (≥3 months) medial meniscus posterior root tear after painful popping events. The exclusion criteria were: other meniscus and anterior cruciate ligament injuries. We measured medial meniscus posterior extrusion and medial meniscus anteroposterior interval at knee flexion angles of 10° and 90° preoperatively and at 3 months postoperatively. The posterior extrusion at 90° knee flexion decreased from 4.42±1.38 mm preoperatively to 3.09±1.06 mm (p<0.001) postoperatively, while at 10° knee flexion it was −4.17±1.63 mm preoperatively and −3.77±1.72mm postoperatively, showing no significant change. The anteroposterior interval at 10° knee flexion increased from 19.74±4.27 mm preoperatively to 22.15±5.10 mm postoperatively (p<0.001); at 90° knee flexion, it increased from 16.81±4.51 mm preoperatively to 19.20±4.30 mm postoperatively (p<0.001). Medial meniscus posterior extrusion and movement decreased after pullout repair. Pullout repair for medial meniscus posterior root tear improves medial meniscus posterior extrusion, especially at 90° knee flexion. en-copyright= kn-copyright= en-aut-name=MasudaShin en-aut-sei=Masuda en-aut-mei=Shin 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=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=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=HiranakaTakaaki en-aut-sei=Hiranaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of 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=medial meniscus posterior root tear kn-keyword=medial meniscus posterior root tear en-keyword=pullout repair kn-keyword=pullout repair en-keyword=extrusion kn-keyword=extrusion en-keyword=open magnetic resonance imaging kn-keyword=open magnetic resonance imaging END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=6 article-no= start-page=475 end-page=477 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 Aging Population and Research into Treatments for Abdominal Aortic Aneurysms en-subtitle= kn-subtitle= en-abstract= kn-abstract= Abdominal aortic aneurysms (AAAs) usually expand asymptomatically until the occurrence of a life-threatening event such as aortic rupture, which is closely associated with high mortality. AAA and aortic dissection are ranked among the top 10 causes of death in Japan. The major risk factors for AAA are age over 65 years, male gender, family history, and smoking. Thus, for prevention, smoking cessation is the most important lifestyle-intervention. For treatment, since AAA generally affects elderly people, less invasive treatment is preferable. However, the only established treatment for AAA is open repair and endovascular repair. This review describes potential medical treatments to slow aneurysm growth or prevent AAA rupture. en-copyright= kn-copyright= en-aut-name=UmebayashiRyoko en-aut-sei=Umebayashi en-aut-mei=Ryoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UchidaHaruhito A. en-aut-sei=Uchida en-aut-mei=Haruhito A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WadaJunzo en-aut-sei=Wada en-aut-mei=Junzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, 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= en-keyword=abdominal aortic aneurysms kn-keyword=abdominal aortic aneurysms en-keyword=medical treatment kn-keyword=medical treatment en-keyword=anti-platelet drugs kn-keyword=anti-platelet drugs END start-ver=1.4 cd-journal=joma no-vol=484 cd-vols= no-issue= article-no= start-page=394 end-page=401 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20180925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Syntheses and crystal structures of neodymium(III) and europium(III) complexes bearing dimethyl-, pyrrolidine-, or S-prolinol- dithiocarbamato ligands and their natural and magnetic circular dichroism spectra en-subtitle= kn-subtitle= en-abstract= kn-abstract= A series of Nd-III and Eu-III complexes containing achiral or chiral dithiocarbamato (dtc) ligands, [Ln(Xdtc)(3)(NN)] {Ln = Nd or Eu; X = dimethyl- (Me-2), pyrrolidine- (pyr), or (S)-prolinol- (S-proOH); NN = 1,10-phenanthroline (phen) or 2,2'-bipyridine (bpy)}, were prepared and their crystal structures and spectroscopic properties, in particular the natural circular dichroism (CD) and magnetic circular dichroism (MCD), were investigated. The crystal structures of the complexes analyzed by the X-ray diffraction method showed an 8-coordinate geometry around the Ln III center with comparable structural parameters to one another and to the related complexes reported previously. These complexes exhibited similar spectral patterns in their absorption, natural CD and MCD spectra in solution. Weak but characteristic sharp f-f transition bands were observed in the absorption and MCD spectra, but no CD signals associated with these transitions were observed even in the S-proOHdtc complexes. The MCD spectral pattern of the Eu-III complexes revealed a local C-2v symmetry around the Ln(III) center in solution, in contrast to the aqua and the analogous beta-diketonato Eu-III complexes. en-copyright= kn-copyright= en-aut-name=YakubuAbdallah en-aut-sei=Yakubu en-aut-mei=Abdallah kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiTakayoshi en-aut-sei=Suzuki en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KitaMasakazu en-aut-sei=Kita en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Education, Okayama University kn-affil= en-keyword=Dithiocarbamate kn-keyword=Dithiocarbamate en-keyword=Lanthanoid kn-keyword=Lanthanoid en-keyword=Crystal structures kn-keyword=Crystal structures en-keyword=Magnetic circular dichroism kn-keyword=Magnetic circular dichroism en-keyword=(S)-prolinol dithiocarbamate kn-keyword=(S)-prolinol dithiocarbamate 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. Recent genetic and epigenetic analyses of glioma have revealed increasing evidence of the role of driver genetic alterations in glioma development and led to the identification of prognostic factors. 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=229 end-page=233 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=Lights-out Surgery for Strabismus Using a Heads-Up 3D Vision System en-subtitle= kn-subtitle= en-abstract= kn-abstract= During strabismus surgery using illumination from a light source, patients complain of photophobia. The NGENUITYⓇ (Alcon) system is equipped with a high-dynamic-range (HDR) camera. A 4K display viewed by wearing circularly polarized glasses provides clear three-dimensional images of the operative field. A light source is usually required for surgeries of the anterior segment (including strabismic surgery), but the digital processing function of the NGENUITYⓇ system allows image display in relatively dark regions even without a light source. We devised a novel ‘lights-out’ surgery that does not use a microscope’s light source, and we examined the usefulness of this technique in 2 cases of strabismic surgery. We performed strabismus surgery using the NGENUITYⓇ system in two patients between January and June 2018. The HDR function was used, and the aperture was opened to the maximum while the gain was adjusted. Surgery was conducted without using the microscope’s light source. We report the 2 cases’ results and evaluate the novel method. The surgeries were performed without problem even though the microscope’s light source was not used. The patients’ photophobia was alleviated. Lights-out surgery is a potentially useful modality for strabismus surgery. en-copyright= kn-copyright= en-aut-name=HamasakiIchiro en-aut-sei=Hamasaki en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShibataKiyo en-aut-sei=Shibata en-aut-mei=Kiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimizuTakehiro en-aut-sei=Shimizu en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KonoReika en-aut-sei=Kono en-aut-mei=Reika 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, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Ophthalmology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Ophthalmology, Okayama University 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 Hospital kn-affil= affil-num=6 en-affil=Department of Ophthalmology, Okayama University Hospital kn-affil= en-keyword=head-up surgery kn-keyword=head-up surgery en-keyword=3D vision system kn-keyword=3D vision system en-keyword=high dynamic range kn-keyword=high dynamic range en-keyword=video enhancement kn-keyword=video enhancement en-keyword=strabismus surgery kn-keyword=strabismus surgery END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=2 article-no= start-page=101 end-page=107 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201904 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Factors Affecting the Absorption of Midazolam to the Extracorporeal Membrane Oxygenation Circuit en-subtitle= kn-subtitle= en-abstract= kn-abstract= Sedatives are administered during extracorporeal membrane oxygenation (ECMO) therapy to ensure patient safety, reduce the metabolic rate and correct the oxygen supply-demand balance. However, the concentrations of sedatives can be decreased due to absorption into the circuit. This study examined factors affecting the absorption of a commonly used sedative, midazolam (MDZ). Using multiple ex vivo simulation models, three factors that may influence MDZ levels in the ECMO circuit were examined: polyvinyl chloride (PVC) tubing in the circuit, use of a membrane oxygenator in the circuit, and heparin coating of the circuit. We also assessed changes in drug concentration when MDZ was re-injected in a circuit. The MDZ level decreased to approximately 60% of the initial concentration in simulated circuits within the first 30 minutes. The strongest factor in this phenomenon was contact with the PVC tubing. Membrane oxygenator use tended to increase MDZ loss, whereas heparin circuit coating had no influence on MDZ absorption. Similar results were obtained when a second dose of MDZ was injected to the second-use circuits. en-copyright= kn-copyright= en-aut-name=IidaAtsuyoshi en-aut-sei=Iida en-aut-mei=Atsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=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=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamadaAkane en-aut-sei=Yamada en-aut-mei=Akane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KogaTadashi en-aut-sei=Koga en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ImaiToru en-aut-sei=Imai en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SendoToshiaki en-aut-sei=Sendo en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IchibaShingo en-aut-sei=Ichiba en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Emergency and 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 and Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Human Ecology, Okayama University Graduate School of Environmental and Life Science kn-affil= affil-num=4 en-affil=Department of Clinical Pharmacy, Institute of Biomedical Sciences, Tokushima University Graduate School kn-affil= affil-num=5 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=6 en-affil=Drug Safety Research Laboratories, Shin Nippon Biomedical Laboratories, Ltd. kn-affil= affil-num=7 en-affil=Department of Pharmacy, Nihon University Itabashi Hospital kn-affil= affil-num=8 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Emergency and Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Surgical Intensive Care Medicine, Nippon Medical School Hospital kn-affil= en-keyword=sedatives kn-keyword=sedatives en-keyword=ECMO kn-keyword=ECMO en-keyword=polyvinyl chloride kn-keyword=polyvinyl chloride en-keyword=pharmacokinetics kn-keyword=pharmacokinetics en-keyword=pharmacodynamics kn-keyword=pharmacodynamics END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=1 article-no= start-page=15 end-page=20 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=High-flow Nasal Cannula Versus Noninvasive ventilation for Postextubation Acute Respiratory Failure after Pediatric Cardiac Surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract= We compared the reintubation rate in children who received high-flow nasal cannula (HFNC) therapy to the rate in children who received noninvasive ventilation (NIV) therapy for acute respiratory failure (ARF) after cardiac surgery. This was a retrospective analysis of 35 children who received HFNC therapy for ARF after cardiac surgery in 2014-2015 (the HFNC group). We selected 35 children who had received NIV therapy for ARF after cardiac surgery in 2009-2012 as a control group. The matching parameters were body weight and risk adjustment for congenital heart surgery category 1. The reintubation rate within 48 h in the HFNC group tended to be lower than that in the NIV group (3% vs. 17%, p=0.06). The reintubation rate within 28 days was significantly lower in the HFNC group compared to the NIV group (3% vs. 26%, p=0.04). The HFNC group’s ICU stays were significantly shorter than those of the NIV group: 10 (IQR: 7-17) days vs. 17 (11-32) days, p=0.009. HFNC therapy might be associated with a reduced reintubation rate in children with ARF after cardiac surgery. en-copyright= kn-copyright= en-aut-name=ShiojiNaohiro en-aut-sei=Shioji en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=IwasakiTatsuo en-aut-sei=Iwasaki en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShimizuKazuyoshi en-aut-sei=Shimizu en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SuemoriTomohiko en-aut-sei=Suemori en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KuroeYasutoshi en-aut-sei=Kuroe en-aut-mei=Yasutoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital 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 Hospital kn-affil= affil-num=4 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= en-keyword=high-flow nasal cannula kn-keyword=high-flow nasal cannula en-keyword=noninvasive ventilation kn-keyword=noninvasive ventilation en-keyword=reintubation kn-keyword=reintubation en-keyword=congenital heart disease kn-keyword=congenital heart disease en-keyword=acute respiratory failure kn-keyword=acute respiratory failure END start-ver=1.4 cd-journal=joma no-vol=44 cd-vols= no-issue=4 article-no= start-page=449 end-page=454 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201704 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Usefulness of serum 5-S-cysteinyl-dopa as a biomarker for predicting prognosis and detecting relapse in patients with advanced stage malignant melanoma en-subtitle= kn-subtitle= en-abstract= kn-abstract= With the recent development of novel molecular targeted drugs for advanced stage malignant melanoma (MM), including RAF and mitogen-activated protein kinase kinase inhibitors and immune checkpoint blockers, the early detection of relapse is important for managing patients with MM. In this study, we retrospectively analyzed two conventional serum biomarkers, 5-S-cysteinyl-dopa and lactate dehydrogenase, in patients with MM (n = 140) who were treated at a single Japanese institute from June 2007 to June 2015. At the initial hospital visit, serum 5-S-cysteinyl-dopa levels were significantly increased in patients with stages III (n = 38) and IV (n = 20) MM compared with patients with stages 0-II (n = 62) MM. In addition, in patients with stages III and IV MM, serum 5-S-cysteinyl-dopa levels of more than 15.0 nmol/L at initial hospital visit correlated with a poor prognosis. In 11 of 14 patients whose disease progressed during follow up (mostly from stages III-IV), serum 5-S-cysteinyl-dopa levels exceeded the normal limit of 10.0 nmol/L during the clinical detection of distant metastases. These results indicate the usefulness of measuring serum 5-S-cysteinyl-dopa levels at initial hospital visit and during follow up for early and effective therapeutic interventions using newly developed molecular targeted drugs. en-copyright= kn-copyright= en-aut-name=HiroshiUmemura en-aut-sei=Hiroshi en-aut-mei=Umemura kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamasakiOsamu en-aut-sei=Yamasaki en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KajiTatsuya en-aut-sei=Kaji en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OtsukaMasaki en-aut-sei=Otsuka en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AsagoeKenji en-aut-sei=Asagoe en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakataMinoru en-aut-sei=Takata en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IwatsukiKeiji en-aut-sei=Iwatsuki en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Division of Dermatology, Shizuoka Cancer Center Hospital kn-affil= affil-num=5 en-affil=Department of Dermatology, National Hospital Organization Okayama Medical Center kn-affil= affil-num=6 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=5-S-cysteinyl-dopa kn-keyword=5-S-cysteinyl-dopa en-keyword=biomarker kn-keyword=biomarker en-keyword=lactate dehydrogenase kn-keyword=lactate dehydrogenase en-keyword=malignant melanoma kn-keyword=malignant melanoma en-keyword=serum 5-S-CD kn-keyword=serum 5-S-CD END start-ver=1.4 cd-journal=joma no-vol=129 cd-vols= no-issue=1 article-no= start-page=41 end-page=44 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=Thoracoscopic esophagectomy was effective in a case of lower esophageal stenosis due to recurrence of achalasia after myotomy 40 years previously kn-title=40年経過した食道アカラシア術後の食道拡張・下部食道狭窄症に 対して胸腔鏡下食道亜全摘が著効した1例 en-subtitle= kn-subtitle= en-abstract= kn-abstract= When planning surgery for achalasia, it is important to plan for adequate myotomy and prevention of reflux. However, achalasia may recur if the procedure was inadequate or in patients with a long-term course. The present case is a 68-year-old woman who underwent myotomy of the lower esophageal sphincter 40 years ago, but recently reported difficulty in swallowing. Dilatation of the thoracic esophagus and stenosis of the abdominal esophagus were identified by examination, and the patient was diagnosed with recurrence of achalasia. After percutaneous endoscopic gastrostomy was performed to recover nutritional status, thoracoscopic esophagectomy was carried out. The patient'spost-operative course was uneventful and oral intake was enabled. At the time of writing, there has been no re-recurrence. There is no standard therapy for post-operative recurrence of achalasia. We believe that thoracoscopic esophagectomy for the recurrence of achalasia is a safe and minimally invasive alternative to conventional surgery. en-copyright= kn-copyright= en-aut-name=KatsuraYuki en-aut-sei=Katsura en-aut-mei=Yuki kn-aut-name=桂佑貴 kn-aut-sei=桂 kn-aut-mei=佑貴 aut-affil-num=1 ORCID= en-aut-name=ShirakawaYasuhiro en-aut-sei=Shirakawa en-aut-mei=Yasuhiro kn-aut-name=白川靖博 kn-aut-sei=白川 kn-aut-mei=靖博 aut-affil-num=2 ORCID= en-aut-name=TanabeShunsuke en-aut-sei=Tanabe en-aut-mei=Shunsuke kn-aut-name=田邊俊介 kn-aut-sei=田邊 kn-aut-mei=俊介 aut-affil-num=3 ORCID= en-aut-name=MaedaNaomi en-aut-sei=Maeda en-aut-mei=Naomi kn-aut-name=前田直見 kn-aut-sei=前田 kn-aut-mei=直見 aut-affil-num=4 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name=野間和広 kn-aut-sei=野間 kn-aut-mei=和広 aut-affil-num=5 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=6 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil=岡山大学病院 消化管外科 affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil=岡山大学病院 消化管外科 affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil=岡山大学病院 消化管外科 affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil=岡山大学病院 消化管外科 affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil=岡山大学病院 消化管外科 affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil=岡山大学病院 消化管外科 en-keyword=食道アカラシア (achalasia) kn-keyword=食道アカラシア (achalasia) en-keyword=再手術 (reoperation) kn-keyword=再手術 (reoperation) en-keyword=食道亜全摘 (esophagectomy) kn-keyword=食道亜全摘 (esophagectomy) END start-ver=1.4 cd-journal=joma no-vol=128 cd-vols= no-issue=1 article-no= start-page=21 end-page=25 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=20160401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A case of mucinous adenocarcinoma of the duodenum and literature review of 16 cases reported in Japan kn-title=原発性十二指腸粘液癌の一例― 本邦報告16例の検討― en-subtitle= kn-subtitle= en-abstract= kn-abstract= Primary mucinous adenocarcinoma of the duodenum is rare. Here we report a case we recently encountered, and we review 16 cases reported in Japan. An 82-year-old Japanese woman was admitted to our hospital complaining of abdominal pain and heartburn. An endoscopic examination revealed a Type 2 tumor in the descending limb of the duodenum, and endoscopically obtained specimens revealed a poorly differentiated adenocarcinoma. We performed a curative pancreatoduodenectomy with lymph node resection, and the surgical specimen revealed that the duodenum was the primary site of the mucinous adenocarcinoma. The patient is currently alive > 1 year after the operation without any evidence of recurrence. Of the 16 patients reviewed, all patients had advanced tumors those depth were T3-T4. 9 patients had lymph node metastasis and 4 patients had peritoneal dissemination at the time of surgery. Since mucinous adenocarcinoma of the duodenum is often progressive cancer at a diagnosis, which is tend to have a worse prognosis than other histological types. en-copyright= kn-copyright= en-aut-name=HamanoIkumi en-aut-sei=Hamano en-aut-mei=Ikumi kn-aut-name=浜野郁美 kn-aut-sei=浜野 kn-aut-mei=郁美 aut-affil-num=1 ORCID= en-aut-name=MatsumotoYusuke en-aut-sei=Matsumoto en-aut-mei=Yusuke kn-aut-name=松本祐介 kn-aut-sei=松本 kn-aut-mei=祐介 aut-affil-num=2 ORCID= en-aut-name=EndoYoshikatsu en-aut-sei=Endo en-aut-mei=Yoshikatsu kn-aut-name=遠藤芳克 kn-aut-sei=遠藤 kn-aut-mei=芳克 aut-affil-num=3 ORCID= en-aut-name=WatanabeNaoki en-aut-sei=Watanabe en-aut-mei=Naoki kn-aut-name=渡邊直樹 kn-aut-sei=渡邊 kn-aut-mei=直樹 aut-affil-num=4 ORCID= en-aut-name=KaiKyouhei en-aut-sei=Kai en-aut-mei=Kyouhei kn-aut-name=甲斐恭平 kn-aut-sei=甲斐 kn-aut-mei=恭平 aut-affil-num=5 ORCID= en-aut-name=SatoShizou en-aut-sei=Sato en-aut-mei=Shizou kn-aut-name=佐藤四三 kn-aut-sei=佐藤 kn-aut-mei=四三 aut-affil-num=6 ORCID= en-aut-name=WaniYoji en-aut-sei=Wani en-aut-mei=Yoji kn-aut-name=和仁洋治 kn-aut-sei=和仁 kn-aut-mei=洋治 aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=姫路赤十字病院 外科 affil-num=2 en-affil= kn-affil=姫路赤十字病院 外科 affil-num=3 en-affil= kn-affil=姫路赤十字病院 外科 affil-num=4 en-affil= kn-affil=姫路赤十字病院 外科 affil-num=5 en-affil= kn-affil=姫路赤十字病院 外科 affil-num=6 en-affil= kn-affil=姫路赤十字病院 外科 affil-num=7 en-affil= kn-affil=姫路赤十字病院 病理診断科 en-keyword=原発性十二指腸癌(primary duodenal cancer) kn-keyword=原発性十二指腸癌(primary duodenal cancer) en-keyword=粘液癌(mucinous carcinoma) kn-keyword=粘液癌(mucinous carcinoma) en-keyword=膵頭十二指腸切除(pancreatoduodenectomy) kn-keyword=膵頭十二指腸切除(pancreatoduodenectomy) END start-ver=1.4 cd-journal=joma no-vol=126 cd-vols= no-issue=3 article-no= start-page=187 end-page=190 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The 2013 Incentive Award of the Okayama Medical Association in General Medical Science (2013 Yuuki Prize) kn-title=平成25年度岡山医学会賞 総合研究奨励賞(結城賞) en-subtitle= kn-subtitle= en-abstract= kn-abstract=受賞対象論文: Yamamoto H, Higasa K, Sakaguchi M, Shien K, Soh J, Ichimura K, Furukawa M, Hashida S, Tsukuda K, Takigawa N, Matsuo K, Kiura K, Miyoshi S, Matsuda F, Toyooka S:Novel germline mutation in the transmembrane domain of HER2 in familial lung adenocarcinomas.

Patients. generally show an aggressive clinical course and very poor outcome. Although the 2008 World Health Organization classification of PTCL-NOS includes 3 variants, low-grade lymphoma is not Included. Of 277 PTCL-NOS cases recorded in our consultation files, we examined the clinicopathologic characteristics of 10 patients with T-cell lymphomas composed of small-sized cells with slight nuclear atypia. Eight patients showed extranodal involvement (5 patients, spleen; 3 patients, thyroid), and 5 patients were at clinical stage I or II. Histologically, all samples presented diffuse infiltrate of small lymphoid cells, with few mitotic figures. Immunohistologically, all samples were positive for CD3, and CD:20 Was detected in 5 samples. All samples showed a low Ki-67 labeling index (mean, 1.05%), and 7 samples were positive for central memory T-cell markers. Clonal T-cell receptor gamma chain and/or alpha-beta chain gene rearrangements were detected in all 10 patients. Five patients received chemotherapy, whereas for 3 patients, treatment consisted only of observation following surgical resection of the spleen or thyroid. Nine patients were alive at a median follow-up time of 19.5 months, whereas 1 patient died of an unrelated disease. The present study strongly indicates that T-cell lymphoma with small-sized lymphoma cells and a low Ki-67 labeling index is a distinct variant. Recognition of this novel lymphoma subtype, which should not be defined merely as PTCL-NOS, should be seriously considered. en-copyright= kn-copyright= en-aut-name=HayashiEiko en-aut-sei=Hayashi en-aut-mei=Eiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakataKatsuyoshi en-aut-sei=Takata en-aut-mei=Katsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=TashiroYukie en-aut-sei=Tashiro en-aut-mei=Yukie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TachiyamaYoshiro en-aut-sei=Tachiyama en-aut-mei=Yoshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Sawada-KitamuraSeiko en-aut-sei=Sawada-Kitamura en-aut-mei=Seiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HiramatsuYasushi en-aut-sei=Hiramatsu en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugiguchiShun en-aut-sei=Sugiguchi en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NoseSoichiro en-aut-sei=Nose en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HirokawaMitsuyoshi en-aut-sei=Hirokawa en-aut-mei=Mitsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AndoMidori en-aut-sei=Ando en-aut-mei=Midori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=Abd MaderLamia en-aut-sei=Abd Mader en-aut-mei=Lamia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=TanimotoMitsune en-aut-sei=Tanimoto en-aut-mei=Mitsune kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 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=15 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Pathol affil-num=2 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Pathol affil-num=3 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Pathol affil-num=4 en-affil= kn-affil=Imakiire Gen Hosp, Dept Pathol affil-num=5 en-affil= kn-affil=Hiroshima Nishi Med Ctr, Div Pathol affil-num=6 en-affil= kn-affil=Kanazawa Univ Hosp, Div Pathol affil-num=7 en-affil= kn-affil=Himeji Red Cross Hosp, Dept Hematol & Oncol affil-num=8 en-affil= kn-affil=Tonami Gen Hosp, Dept Pathol affil-num=9 en-affil= kn-affil=Okayama Saiseikai Gen Hosp, Dept Pathol affil-num=10 en-affil= kn-affil=Kuma Hosp, Dept Diagnost Pathol affil-num=11 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Pathol affil-num=12 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Pathol affil-num=13 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Hematol & Oncol affil-num=14 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Hematol & Oncol affil-num=15 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Pathol en-keyword=Indolent PTCL kn-keyword=Indolent PTCL en-keyword=CD20 kn-keyword=CD20 en-keyword=Ki-67 kn-keyword=Ki-67 en-keyword=Memory T cell kn-keyword=Memory T cell en-keyword=Good prognosis kn-keyword=Good prognosis END start-ver=1.4 cd-journal=joma no-vol=55 cd-vols= no-issue=3 article-no= start-page=161 end-page=176 dt-received= dt-revised= dt-accepted= dt-pub-year=1976 dt-pub=19760228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Chemical investigation on inorganic constituents in night soil (excreta) II.

For in vitro and in vivo experiments, MSCs were transfected with adenovirus carrying either enhanced green fluorescent protein gene (AdexCAEGFP) or cytosine deaminase gene (AdexCACD), to establish MSC-expressing EGFP (MSC-EGFP) or CD (MSC-CD). Co-culture of 9L glioma cells with MSC-CD in a medium containing 5-FC resulted in a remarkable reduction in 9L cell viability. The migratory ability of MSC-EGFP toward 9L cells was demonstrated by double-chamber assay. For the in vivo study, rats harboring 9L brain tumors were inoculated with MSC-EGFP or MSC-CD. Immunohistochemistry of rat brain tumors inoculated with MSC-EGFP showed intratumoral distribution of MSC-EGFP. Survival analysis of rats bearing 9L gliomas treated with intratumoral MSC-CD and intraperitoneal 5-FC resulted in significant prolongation of survival compared with control animals. In conclusion, molecular therapy combining suicide gene therapy and MSCs as a targeting vehicle represents a potential new therapeutic approach for malignant glioma, both with respect to the antitumor potential of this system and its neuroprotective effect on normal brain tissue. en-copyright= kn-copyright= en-aut-name=KosakaH en-aut-sei=Kosaka en-aut-mei=H kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchikawaT en-aut-sei=Ichikawa en-aut-mei=T kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurozumiK en-aut-sei=Kurozumi en-aut-mei=K kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KambaraH en-aut-sei=Kambara en-aut-mei=H kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=InoueS en-aut-sei=Inoue en-aut-mei=S kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MaruoT en-aut-sei=Maruo en-aut-mei=T kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraK en-aut-sei=Nakamura en-aut-mei=K kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HamadaH en-aut-sei=Hamada en-aut-mei=H kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=DateI en-aut-sei=Date en-aut-mei=I kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Neurol Surg affil-num=3 en-affil= kn-affil= affil-num=4 en-affil= kn-affil= affil-num=5 en-affil= kn-affil= affil-num=6 en-affil= kn-affil= affil-num=7 en-affil= kn-affil=Hokkaido Univ, Grad Sch Life Sci, Fac Adv Life Sci, Innate Immun Lab affil-num=8 en-affil= kn-affil=Tokyo Univ Pharm & Life Sci, Dept Life Sci affil-num=9 en-affil= kn-affil= en-keyword=glioma kn-keyword=glioma en-keyword=mesenchymal stem cell kn-keyword=mesenchymal stem cell en-keyword=suicide gene kn-keyword=suicide gene en-keyword=bystander effect kn-keyword=bystander effect END start-ver=1.4 cd-journal=joma no-vol=125 cd-vols= no-issue=1 article-no= start-page=41 end-page=45 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20130401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A case of gastrointestinal stromal tumor with synchronous liver metastases showing long-term disease control by imatinib kn-title=イマチニブが長期に奏効している同時性肝転移を伴う消化管間質腫瘍の1例 en-subtitle= kn-subtitle= en-abstract= kn-abstract= Radical surgery is the primary treatment for gastrointestinal stromal tumor (GIST), so that unrsectable GIST has been considered a fatal disease, and the median duration of survival for patients with an unresectable GIST before the era of molecular targeted therapy has been about 18 months. Since the recent development of agents for molecular targeted therapy, including imatinib mesylate, the prognosis of unrsectable GIST has been dramatically improved. The B2222 trial reported that a median time to progression and a median overall survival for advanced GIST treated with imatinib of 24 months and 57 months, respectively. We recently experienced a case of gastrointestinal stromal tumor with synchronous liver metastases maintained in whom the disease was controlled for 4 years by imatinib. The patient is 37-year-old man and he took imatinib mesylate at 400mg/day with no adverse events. Both primary and metastases lesions responded well to imatinib treatment, and this efficacy has endured for 4 years, such that surgical intervention is now considered possible. While GIST is a relatively rare disease and clinical evidence is still poor, we document our considerations for the therapy in this case as well as the results. en-copyright= kn-copyright=

report herein a case of mesenteric Castleman's disease which was confirmed on pathology. A 60-year-old man was admitted to our hospital complaining of abdominal pain. On the physical examination, there was no palpable mass. Computed tomography findings and magnetic resonance imaging revealed a well circumscribed, lobulated round mass on the right side of the superior mesenteric vein. Laparoscopic surgery for the mesenteric tumor was carried out to obtain a definite diagnosis and treatment. In the operative field, the mass was located on the ascending colic mesentery and measured about 3 cm in size. It was solid and surrounded by a thin fibrous capsule. The histological diagnosis of the mesenteric tumor was hyaline vascular type Castleman's disease. The postoperative course of the patient was uneventful, and he was discharged on the 10th postoperative day. en-copyright= kn-copyright= en-aut-name=NishieManabu en-aut-sei=Nishie en-aut-mei=Manabu kn-aut-name=西江学 kn-aut-sei=西江 kn-aut-mei=学 aut-affil-num=1 ORCID= en-aut-name=OtsukaShinya en-aut-sei=Otsuka en-aut-mei=Shinya kn-aut-name=大塚真哉 kn-aut-sei=大塚 kn-aut-mei=真哉 aut-affil-num=2 ORCID= en-aut-name=TomodaJun en-aut-sei=Tomoda en-aut-mei=Jun kn-aut-name=友田純 kn-aut-sei=友田 kn-aut-mei=純 aut-affil-num=3 ORCID= en-aut-name=FujiwaraKeishi en-aut-sei=Fujiwara en-aut-mei=Keishi kn-aut-name=藤原敬士 kn-aut-sei=藤原 kn-aut-mei=敬士 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=国立病院機構福山医療センター 外科 affil-num=2 en-affil= kn-affil=国立病院機構福山医療センター 外科 affil-num=3 en-affil= kn-affil=国立病院機構福山医療センター 内科 affil-num=4 en-affil= kn-affil=光生病院 内科 en-keyword=結腸間膜 (mesocolon) kn-keyword=結腸間膜 (mesocolon) en-keyword=Castleman病 (Castleman's disease) kn-keyword=Castleman病 (Castleman's disease) en-keyword=腹腔鏡手術 (laparoscopic surgery) kn-keyword=腹腔鏡手術 (laparoscopic surgery) END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=1 end-page=43 dt-received= dt-revised= dt-accepted= dt-pub-year=1951 dt-pub=195108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=CHROMATOGRAPHIC ANALYSIS OF METALS BY ORGANIC REAGENTS (Ist Report) kn-title=有機試藥による金属クロマトグラフ分析法とその応用(第1法) en-subtitle= kn-subtitle= en-abstract= kn-abstract=The principle of this method is to combine the metals with organic reagents, then extract them with non-polar solvents, and determine them by making chromatograph with adequate adsorbents. Dithizone is used to determine Hg, Cd, Bi, Ag, Cu, Zn, Ni, Co, Tl, Pb, Pd and its isotopes, Pt group, Au, etc. Diphenylcarbazone is applicable to determine Hg, Cu, Zn, Ni, etc. Xanthate is useful to determine Mo, Cu, Ni, Co, etc. α-orβ- Nitrosoβ- orα-naphthol is used to determine Fe, Co, earth acids etc. Diethyldithiocarbamate is used to determine Mo, Cu, Ni, Co, Fe, etc. Oxine series are useful to determine Cu, Ni, Fe, V, rare earth etc. α-indolcarbonic acid is applied to determine Fe, Co, rare earth etc. Acethyl acetone is used to determine Th, Fe, etc. Some other organic reagents were used moreover. There are some elements of which necessary condition for quantitative determination is still not decided or the order of adsorption is indefmite. As adsorbents alkaline, neutral or acid alumina, diatom earth and aluminate, magnesium carbonate, calcium carbonate, urea formaline resin, heulandite, mordenite, desmine, chabazite etc· were used. With this method the author tryed severd determinations on rocks, minerals, mineral springs, organisms etc. The contento; of Cu, Zn, Ni and Co in rocks were 0.007, 0.008, 0.002 and 0.004% respectively. Cobalt content proved to be more than that of nickel. The mercury content of rocks was proved to be 10 times more to Clarke number, bismuth and cadmium content as same as or less than Clarke number. Silver in plants, soil and mineral waters, platinum in serpentine; mercury, cadmium, bismuth etc in mineral waters, trace heavy metals in organism, etc were determined. Radium B and Thorium B in hot spring waters were used as tracer. As organic solvents methyl-, ethyl-, butyl-, amy1-, octyl alcohol, dioxan, benzol, toluene, xylol, petroleum ether, ether, ethylacetate, chloloform, carbon tetrachloride, carbon disulfide etc were applied. en-copyright= kn-copyright= en-aut-name=AshizawaTakashi en-aut-sei=Ashizawa en-aut-mei=Takashi kn-aut-name=芦沢峻 kn-aut-sei=芦沢 kn-aut-mei=峻 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学溫泉研究所化学部 END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue= article-no= start-page=1 end-page=9 dt-received= dt-revised= dt-accepted= dt-pub-year=1961 dt-pub=196101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Studies on the coulometric determination of uranium (VI) and Thallium CD by Controlled Potential Electrolysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=In recent years, coulometric analysis has been developed and widely used as a technique for the determination of substances in solution by measuring the quantity of electricity required for the completion of a reaction in an electrolysis cell. Of two coulometric techniques, i. e., coulometric titration with a constant current and coulometric analysis with a controlled potential of a working electrode, the latter is more interesting to the author, because by this method both electrolytic separation and quantitative determination of chemical species can be achieved simultaneously. Especially, the use of a mercury cathode as the working electrode(1)) has an advantage that the optimum control potentials can easily be determinable from polarographic data. In our laboratory, we took up the coulometry of uranium as one of the interesting themes of researches when we had an opPortunity in studying various kinds of analytical methods for uranium in accordance with the request by Japan Atomic Fuel Corporation. The coulometric determination of uranium (VI) by using a mercury cathode at a controlled potential was studied by G. L. Booman, W. B. Holbrook and ]. E. Rein(2)). It was found to be very useful for the analysis of uranium in a highly enriched nuclear element which underwent fission to an appreciable extent. But the instrument used by them(3)) was complicated and expensive. Therefore, a simple counter millicoulometer has been coustructed in our laboratory, a readymade potentiostat (electrical instrument for automatic controlled potential electrolysis) being tried for electrolysis. By these instruments, the author studied the fundam ental conditions of coulometry for uranium and tried the successive determinations of uranium and thallium in mixed solutions. en-copyright= kn-copyright= en-aut-name=SakanoueMasanobu en-aut-sei=Sakanoue en-aut-mei=Masanobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=Division of Chemistry, Balneological Institute, Okayama University Misasa Hot Springs END start-ver=1.4 cd-journal=joma no-vol=122 cd-vols= no-issue=2 article-no= start-page=95 end-page=99 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=20100802 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=TGF-β-Smad3 pathway activates Sox9-dependent chondrogenesis kn-title=TGF-β-Smad3経路と転写因子Sox9による軟骨細胞分化調節 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name=古松毅之 kn-aut-sei=古松 kn-aut-mei=毅之 aut-affil-num=1 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name=尾﨑敏文 kn-aut-sei=尾﨑 kn-aut-mei=敏文 aut-affil-num=2 ORCID= en-aut-name=AsaharaHiroshi en-aut-sei=Asahara en-aut-mei=Hiroshi kn-aut-name=浅原弘嗣 kn-aut-sei=浅原 kn-aut-mei=弘嗣 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 整形外科学 affil-num=2 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 整形外科学 affil-num=3 en-affil= kn-affil=スクリプス研究所 分子実験医学 en-keyword=chondrogenesis kn-keyword=chondrogenesis en-keyword=epigenetic regulation kn-keyword=epigenetic regulation en-keyword=Smad3 kn-keyword=Smad3 en-keyword=Sox9 kn-keyword=Sox9 en-keyword=TGF-β kn-keyword=TGF-β END start-ver=1.4 cd-journal=joma no-vol=54 cd-vols= no-issue=3-4 article-no= start-page=233 end-page=239 dt-received= dt-revised= dt-accepted= dt-pub-year=2006 dt-pub=20064 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Elucidation of the role of the complex in hydride transfer reaction between methylene blue and 1-benzyl-1,4-dihydronictinamide by effect of γ-cyclodextrin en-subtitle= kn-subtitle= en-abstract= kn-abstract=

The kinetics of the hydride transfer reaction between Methylene Blue (MB+) and 1-benzyl-1,4-dihydronicotinamide (BNAH) were studied in 10 % ethanol-90 % water mixed solvents containing β- and γ-cyclodextrins (β-CD and γ-CD). The pseudo-first order rate constant shows kinetic saturation at high initial concentration of BNAH. This indicates the formation of a complex between MB+ and BNAH. The reaction was suppressed by addition of β-CD, but enhanced by addition of γ-CD. MB+ and BNAH were separately accommodated within the β-CD cavity and the cavity walls may protect the activity site of the reactants. On the other hand, in the MB+-BNAH-γ-CD system, the inclusion of the complex between MB+ and BNAH with γ-CD occurred. This effect of γ-CD can distinguish between the productive and non-productive nature of the complex.

The synthesized resin, crosslinked chitosan serine diacetic acid (CCTS-SDA), showed good adsorption behavior toward trace amounts of Cd, Pb, Cu, Ni, V, Ga, Sc, In, and Th in a wide pH range. Additionally, rare earth elements also can be retained on the resin at neutral pH region. The adsorbed elements can be easily eluted with 1 mol L-1 of nitric acid, and their recoveries were found to be 90-100%. The CCTS-SDA was packed in a mini-column, which was then installed in a cornputer-controlled auto-pretreatment system (Auto-Pret System) for on-line trace elements collection and determination with ICP-AES. Experimental parameters which related to the improvement of sensitivity and reproducibility were optimized. The limits of detection (LOD) for 13 elements were found to be in sub-ppb level. The proposed method with CCTS-SDA resin was successfully applied to the determination of trace elements in river water samples. The method was validated by determining a certified reference material of river water, SLRS-4. en-copyright= kn-copyright= en-aut-name=LukmanHakim en-aut-sei=Lukman en-aut-mei=Hakim kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SabarudinAkhmad en-aut-sei=Sabarudin en-aut-mei=Akhmad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=3 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=2 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=3 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=4 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University en-keyword=chelating resin kn-keyword=chelating resin en-keyword=chitosan kn-keyword=chitosan en-keyword=serine diacetic acid moiety kn-keyword=serine diacetic acid moiety en-keyword=trace elements kn-keyword=trace elements en-keyword=on-line pretreatment kn-keyword=on-line pretreatment en-keyword=computer control kn-keyword=computer control en-keyword=inductively coupled plasma-atomic emission spectrometry kn-keyword=inductively coupled plasma-atomic emission spectrometry en-keyword=SLRS-4 kn-keyword=SLRS-4 END start-ver=1.4 cd-journal=joma no-vol=72 cd-vols= no-issue=5 article-no= start-page=1609 end-page=1617 dt-received= dt-revised= dt-accepted= dt-pub-year=2007 dt-pub=20070118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sequential-injection on-line preconcentration using chitosan resin functionalized with 2-amino-5-hydroxy benzoic acid for the determination of trace elements in environmental water samples by inductively coupled plasma-atomic emission spectrometry en-subtitle= kn-subtitle= en-abstract= kn-abstract=

A new chelating resin using chitosan as a base material was synthesized. Functional moiety of 2-amino-5-hydroxy benzoic acid (AHBA) was chemically bonded to the amino group of cross-linked chitosan (CCTS) through the arm of chloromethyloxirane (CCTS-AHBA resin). Several elements, such as Ag, Be, Cd, Co, Cu, Ni, Ph, U, V, and rare earth elements (REEs), could be adsorbed on the resin. To use the resin for on-line pretreatment, the resin was packed in a mini-column and installed into a sequential-injection/automated pretreatment system (Auto-Pret System) coupled with inductively coupled plasma-atomic emission spectrometry (ICP-AES). The sequential-injection/automated pretreatment system was a laboratory-assembled, and the program was written using Visual Basic software. This system can provide easy operation procedures, less reagent consumption, as well as less waste production. Experimental variables considered as effective factors in the improvement sensitivity, such as an eluent concentration, a sample and an eluent flow rate, pH of samples, and air-sandwiched eluent were carefully optimized. The proposed system provides excellent on-line collection efficiency, as well as high concentration factors of analytes in water samples, which results in highly sensitive detection of ultra-trace and trace analysis. Under the optimal conditions, the detection limits of 24 elements examined are in the range from ppt to sub-ppb levels. The proposed method was validated by using the standard reference material of a river water, SLRS-4, and the applicability was further demonstrated to the on-line collection/concentration of trace elements, such as Ag, Be, Cd, Co, Cu, Ni, Ph, U, V, and REEs in water samples.

A sequential injection-square-wave anodic stripping voltammetry (SIA-SWASV) is proposed for the simultaneous determination of Pb(II), Cd(II) and Zn(II), employing an in situ plated bismuth film screen-printed carbon electrode (Bi-SPCE) as a working electrode and hydrochloric acid as a supporting electrolyte. Bi(III) and analyte metal ions were on-line deposited onto a SPCE at -1.4 V vs. Ag/AgCl for 180 s. At a stopped flow, a square-wave voltammogram was recorded from -1.3 to 0 V vs. Ag/AgCl. The experimental conditions were optimized. Under the optimum conditions, the linear ranges were 0 - 70 mu g L-1 for Pb(II) and Cd(II), and 75 - 200 mu g L-1 for Zn(II). The limits of detection (S/N = 3) were obtained at concentrations as low as 0.89 mu g L-1 for Pb(II) and 0.69 mu g L-1 for Cd(II) for a 180-s deposition time. The proposed method was applied to the determination of Pb(II), Cd(II) and Zn(II) in water samples with satisfactory results.

A 34-year-old woman infected with human T cell leukemia virus type-I(HTLV-I) with recurrent thrombocytopenia and various autoantibodies is described. The platelet counts fluctuated between 1.3 x 10(4)/microliters and 14.8 x 10(4)/microliters without any medical treatment, and thrombocytopenia improved with a decrease of platelet-associated IgG (PA-IgG). Autoantibodies such as rheumatoid factor, antinuclear factor, anti-Sm, anti-RNP and anti-SSA antibodies were also recognized. Marker analysis of peripheral mononuclear cells showed an increase in the proportion of CD 25+ cells, CD 3+ HLA-DR+ cells, CD4+ HLA-DR+ cells and CD8+ HLA-DR+ cells. The recurrent thrombocytopenia and development of various autoantibodies in this HTLV-I carrier are speculated to be due to the alteration of B cell functions by T cells infected with HTLV-I.

Proportional changes of lymphocyte subsets in the peripheral blood were monitored by two-color flow-cytometry in seven leukemia patients who had received allogenic bone marrow transplantation (BMT). Lymphocyte counts, and proportions of T and B-cells returned to normal ranges between the 2nd and 12th months after BMT. Activated T-cells prominently increased after BMT, and the values gradually returned toward normal. As to lymphocyte subsets, the proportions of CD 4+ cells had remained low, while those of CD 8+ cells high for a whole observation period after BMT. The changes of CD 4+ cells were caused by the decrease of suppressor-inducer T-cells (CD 4+ Leu 8+). High proportion of CD 8+ cells was mainly associated with increased suppressor T-cells (CD 8+ CD 11+). Among natural killer (NK) cells, highly active NK cells (CD 16+ CD 57-) markedly increased shortly after BMT, and gradually returned to normal. CD 16 -CD 57+ NK cells increased beyond normal ranges after the 2nd month. The incidence or degree of acute and chronic graft-versus-host diseases (GVHD) did not correlate with the changes of any lymphocyte subsets. The present results suggest that the increase of activated T-cells shortly after BMT reflects lymphocyte reconstitution. The prolonged immune deficiency after BMT might be related to either deficient expression of homing receptor (Leu 8 antigen) on CD 4+ cells or increased suppressor T-cells (CD 8+ CD 11+). In addition, the early increase of NK cells after BMT may compensate for the immune deficiency in BMT patients.

Reportedly, thyroid mucosa-associated lymphoid tissue (MALT) lymphoma is closely associated with Hashimoto's thyroiditis. However, it remains unknown which antigen is closely associated with thyroid MALT lymphoma. We examined whether B cell response to thyroglobulin (Tg), which is a common thyroid-specific autoantigen, is related etiologically to the pathogenesis of thyroid MALT lymphoma. Expression of human Tg antigens and Cluster of differentiation (CD) 35 was examined immunohistochemically in 15 cases of thyroid MALT lymphoma using paraffin-embedded, formalin-fixed tissue specimens. In all cases of thyroid MALT lymphoma, human Tg was detected immunohistochemically in the follicular epithelial cells and follicular dendritic cells (FDCs). These FDCs were positive by double immunostaining for anti-human Tg rabbit polyclonal antibody (Ab) and for CD35. Results showed that the Tg, a thyroid autoantigen, had immunostained the germinal center of the thyroid MALT lymphoma. The Tg was present in the FDCs, as revealed by the staining pattern of the germinal center;this fact was confirmed by double immunostaining of anti-human Tg mouse monoclonal Ab and anti-CD35 mouse monoclonal Ab. The results of our study suggest that Tg is an autoantigen that is recognized by thyroid MALT lymphoma cells.

Ring DNA from rat liver mitochondria has been examined by circular dichroism (CD) in the region of the 225 to 320 m/~ and the followings have been clarified. The ring DNA gives a CD spectral curve somewhat different from linear DNA from nuclei, showing a big positive peak at 266 m/~ and a small negative band at 243 m!~. That is, the positive CD band of ring DNA shifted by about 7 m/~ to the shorter wavelength side from the band of the ordinary nuclear DNA, 273 m!~. Negative band appeared at the same region as that of linear DNA but reduced in depth. Heat denaturation of the ring DNA induced a red shift of the positive band, by about 4 mp., but no change in negative band. From these experimental results it has been concluded that the ring DNA has highly twisted conformation and high in G.C contents, both of which are responsible for the blue shift of the CD spectrum.

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.

ICP-MS has sufficient sensitivity to detect even below the concentrations of ppt level, and therefore the samples were not pretreated with a concentration column. Practical samples were diluted by lo-fold with ultrapure water and measured directly by ICP-MS. The measuring time of one sample was 2.5 min, and the data for 30 elements were obtained simultaneously. The concentrations of heavy metals, such as Cr, Mn, Co, Ni, Cu, Zn, As, Cd, Sb, and Pb, in the water samples were in the ranges of 0.05~82ng/ml. Zasu river and Sibukawa (sea water) contained various kinds of metals, and the concentration ranges were spread in a wide range; for example, Mg was 25700 ppb and In was 2 ppt. ICP-MS is found to be a useful and a powerful instrument for trace amounts of elements, and can be applied satisfactorily to the environmental water analysis. en-copyright= kn-copyright= en-aut-name=LeeKyue-Hyung en-aut-sei=Lee en-aut-mei=Kyue-Hyung kn-aut-name=李啓熒 kn-aut-sei=李 kn-aut-mei=啓熒 aut-affil-num=1 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=2 ORCID= en-aut-name=TakayanagiToshio en-aut-sei=Takayanagi en-aut-mei=Toshio kn-aut-name=高柳俊夫 kn-aut-sei=高柳 kn-aut-mei=俊夫 aut-affil-num=3 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部化学科 affil-num=2 en-affil= kn-affil=岡山大学理学部化学科 affil-num=3 en-affil= kn-affil=岡山大学理学部化学科 affil-num=4 en-affil= kn-affil=岡山大学理学部化学科 END start-ver=1.4 cd-journal=joma no-vol=36 cd-vols= no-issue=3 article-no= start-page=207 end-page=209 dt-received= dt-revised= dt-accepted= dt-pub-year=1987 dt-pub=19870305 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Spectrophotometric determination of nitrate ion using nitrosation/FIA kn-title=ニトロソ化反応を利用する硝酸イオンのフローインジェクション/吸光光度法 en-subtitle= kn-subtitle= en-abstract= kn-abstract=N, N-Bis (2-hydroxypropyl) aniline (BHPA) reacts with nitrite ion in an acidic medium to form a red product, which has the maximum absorption at 500 nm.

Nitrate ion could be reduced to nitrite ion by passing through the reduction column(2 mm×30 cm) packed with copperized cadmium {Cu(Cd) : particle size, about 0.5 mm}, which was installed just behind the sample injection valve. The carrier solution(10(-3) M EDTA, pH 8) and the reagent solution (8×10(-4) M BHPA, 0.35 M HCl, 0.15 M H(3)PO(4)) were propelled at the flow rate of 0.7 ml/min by using a double-plunger pump. The sample(120 μl) was injected into the carrier stream by using a 6-way injection valve. The reaction coil(0.5 mm×2 m) was kept in a thermostatically controlled water bath(80℃). The cooling coil(0.5 mm×50 cm), which was installed just behind the reaction coil, was kept in a water bath (tap water temperature). A calibration curve was linear up to 2×10(-4) M nitrate. The detection limit corresponding to S/N=2 was 10(-6) M nitrate, and the relative standard deviation (10 injections) was 0.4%, and the sampling rate was 40 samples per hour. Nitrate in river water at concentrations of 10(-5) M level was determined. en-copyright= kn-copyright= en-aut-name=ShiCheng Rui en-aut-sei=Shi en-aut-mei=Cheng Rui kn-aut-name=石成瑞 kn-aut-sei=石 kn-aut-mei=成瑞 aut-affil-num=1 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=2 ORCID= en-aut-name=ToeiKyoji en-aut-sei=Toei en-aut-mei=Kyoji kn-aut-name=桐栄恭二 kn-aut-sei=桐栄 kn-aut-mei=恭二 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=FIA of nitrate kn-keyword=FIA of nitrate en-keyword=reduction of nitrate to nitrite on Cu (Cd) column kn-keyword=reduction of nitrate to nitrite on Cu (Cd) column en-keyword=color reaction of nitrite with N kn-keyword=color reaction of nitrite with N END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=7 article-no= start-page=731 end-page=738 dt-received= dt-revised= dt-accepted= dt-pub-year=2000 dt-pub=20000710 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Simultaneous Determination of Trace Elements in River-water Samples by ICP-MS in Combination with a Discrete Microsampling Technique after Enrichment with a Chitosan-based Chelating Resin en-subtitle= kn-subtitle= en-abstract= kn-abstract=A new technique for the preconcentration of trace elements and matrix elimination with a chitosan-based chelating resin was proposed as a useful pretreatment prior to a measurement by inductively coupled plasma-mass spectrometry (ICP-MS). A small volume of the sample solution (80 µl) was discretely introduced into a nebulizer of ICP-MS using a segmented flow injection (SFI) system; a maximum of fifteen elements were simultaneously measured by a single injection. A chitosan-based chelating resin containing iminodiacetate (IDA) functional groups was used for matrix elimination and enrichment of analyte metal ions. Several metal ions, such as Al, Fe, Ni, Co, Cu, Zn, Ag, Cd, Pb and U, were quantitatively retained on the IDA chelating resin in a micro-column (resin: 1 ml) at pH 6, whereas Na, K, Mg and Ca were completely eluted from the column by washing with an ammonium acetate solution. The concentrations of 24 and 26 elements in river water certified reference materials, JAC 0031 and JAC 0032, respectively, were determined by the proposed SFI/ICP-MS system after pretreating the samples with the proposed technique, as well as without any pretreatment. The thus-obtained analytical data were evaluated by comparing them with the reference values, as well as with those obtained in other studies. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=LeeKyue-Hyung kn-aut-sei=Lee kn-aut-mei=Kyue-Hyung aut-affil-num=1 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=2 ORCID= en-aut-name=TakayanagiToshio en-aut-sei=Takayanagi en-aut-mei=Toshio kn-aut-name=高柳俊夫 kn-aut-sei=高柳 kn-aut-mei=俊夫 aut-affil-num=3 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=42 cd-vols= no-issue=12 article-no= start-page=873 end-page=880 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=19931205 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Separation of metal ions and the determination of calcium and magnesium ions with N, N'-di(2-hydroxybenzyl)ethylenediamine-N, N'-diacetic acid by high-performance capillary electrophoresis kn-title=キャピラリー電気泳動によるN,N'-ジ(2-ヒドロキシベンジル)エチレンジアミン-N,N'-二酢酸を用いる金属イオンの分離とカルシウム及びマグネシウムイオンの定量 en-subtitle= kn-subtitle= en-abstract=The capillary electrophoresis study was carried out by using HBED as a chelating and coloring agent.

When a carrier containing 2 × 10(-3) M HBED (pH 10.5) and sample solutions containing 1 × 10(-4) M HBED were used, the mobilities of the metal ions (absolute value) increased in the following order: Co(2+) (Co(3+)) (2.05) < Mn(2+) (2.10) < Al(3+) (2.12) < Fe(3+) (2.15) < Pb(2+) (2.64)> AKR>BALB/c>A>ddT=C57 Br/cd. 2. The minimum lethal dose of CF-1 mice was 1.2 mg by means of intravenous injection. 3. The lethality within 4 weeks of CF-1 mice administered 1.0 mg of the culture intracranially, intravenously, intraperitoneally and by inhalation was 90, 80, 40 and 30 per cent respectively. 4. The most extensive and general pathologic changes were observed in the mice received intravenous injections, and in other cases the lesions produced were more or less localized at the site of invasion. The nature of changes was mostly to be interpreted as productive and granulomatous inflammations of the reticulo-endothelial system. 5. Small form fungi were well distributed in the reticulo-endothelial system and a small number of large form ones were seen in desqumative epithelial cells and in necrotic lesions. 6. The large form organisms were polymorphous being 5 to 20 μ in diameter and budding and chain-formation were infrequently observed. They were not appreciably stained with hematoxylin and eosin, but readily demonstrated by Gridley's stain. 7. The presenting pathologic appearances reached their peak in 2 to 3 weeks and then signs of improvement started to develop. en-copyright= kn-copyright= en-aut-name=MimuraKozi en-aut-sei=Mimura en-aut-mei=Kozi kn-aut-name=三村宏二 kn-aut-sei=三村 kn-aut-mei=宏二 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科教室 END start-ver=1.4 cd-journal=joma no-vol=84 cd-vols= no-issue=9-10 article-no= start-page=307 end-page=320 dt-received= dt-revised= dt-accepted= dt-pub-year=1972 dt-pub=19721030 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Study on Cell Membrane Structure by Circular Dichroism -Changes in the protein structure after chemical fixation of mitochondrial particles, red cell membrane and bovine serum albumin, as well as a proposal for a cell membrane model- kn-title=細胞膜構造の円偏光二色性による研究 ミトコンドリヤ,赤血球膜および牛血清アルブミンの化学的固定によるタンパク質構造の変化と細胞膜モデルの考察 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recently, as the secondary structure of protein structure has come to be distinctly reflected by the ultraviolet circular dichroism (CD) spectrum, an attention has been called to the protein structure of cell membrane by circular dichroism. Lenard and Singer have demonstrated by CD spectrum that the chemical fixation of the cell membrane induces changes in the structure of native red cell membrane, but it is not clear whether or not their conclusion is applicable in common to the membrane of other cells. One of the objects of the present study was to clarify whether the conclusion of Lenard-Singer can be applied generally. For this purpose the author studied changes in the protein structure occurring after the chemical fixation of mitochondrial particles of the rabbit liver and rabbit red cell membrane and bovine serum albumin. It seems quite significant to elucidate the general applicability of their conclusion by clarifying the conformational changes in cell membraneous proteins and other proteins induced by the chemical fixation as it would offer a great parameter to grasp the molecular structure of native cell membrane. The second objective was to elucidate the specific phenomenon, i.e. the cause of red shift of the cell membrane, by the circular dichroism. On the basis of the findings obtained in the observations of those changes occurring in mitochondrial particles, red cell membraines and bovine serum albumin after the chemical fixation, the author proposes here a dynamic cell membrane model as suggested by Seno. The results of the study may be briefly summarized as follows. 1) In the investigation of spectra of the BSA fixed with formaldehyde it has been clearly demonstrated that the aggregation of protein molecules induces the red-shift of the CD spectrum confirming the theory of Lenard-Singer to be valid. 2) Of the findings reported by Lenard-Singer, the facts that chemical fixation induces about 30% (corrected value, 50% ) adhesion of helical structure to the cell membrane, and that the chemical fixation with KMnO(4) brings about the loss of 100% helical structure of the membraneous protein molecules were also demonstrated similarly in the rabbit liver mitochondrial particles and rabbit red cell membrane, indicating that these findings are fairly common in all kinds of cells. 3) However, the extent of conformational changes in the cell membrane induced by the fixation with KMnO(4), OsO(4) or glutaraldehyde as concluded by Lenard-Singer differs from author's own finding. Regarding this problem it seems to be desirable to study further many other kinds of cells. 4) Noting the resemblance of the CD spectrum of BSA fixed with formaldehyde to that of the cell membrane, the author has assumed that the cell membraneous protein molecules are arranged in the form of aggregation. On the basis of this assumption the author has proposed a modified form of the unit membrane model. This modified unit membrane model has the possibility of being readily transposed to a particulate unit model and it has been designed from the perspective of the circular dichroids as against the dynamic membrane model proposed by Seno. en-copyright= kn-copyright= en-aut-name=ItoNobutaka en-aut-sei=Ito en-aut-mei=Nobutaka kn-aut-name=伊藤信隆 kn-aut-sei=伊藤 kn-aut-mei=信隆 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部病理学教室 END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=1-2 article-no= start-page=39 end-page=50 dt-received= dt-revised= dt-accepted= dt-pub-year=1976 dt-pub=19760228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The effects of heavy metals on developing sea urchin eggs. kn-title=ウニ卵の発生に及ぼす重金属の影響 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effects of heavy metals, such as Hg, Pb, Cu, Cd, As, Sn, Cr, Mn, Ni and Zn on the two developing sea urchin eggs. Temnopleurus and Hemicentrotus were investigated. The results obtained were as follows. 1. The development of fertilized eggs was inhibited when embryos were exposed to 10(-6) M of HgCl(2) and CuCl(2) and to 10(-4) M of CrCl(2) and NiCl(2) in Herbst's artificial seawater from fertilization until the formation of the blastula larva. 2. Chlorate and acetate of heavy metals were dissolved in filtered seawater. The morphological differences of embryo were not observed until the formation of the pluteus larva in the two solutions. Inhibitory effects were observed when embryos were exposed to seawater at concentrations of 10(-7) M of Hg and Cu, to 10(-6) M of Cd, and to 10(-5) M of Pb, Ni and Zn. At a concentration of 10(-4) M of Cd there were no visible effects until the appearance of swimming blastula larva, but larva development was strongly inhibited at time of bonification from pluteus larva, and there was no further later development. In 10(-6) M Hg, Cr, and Ni, the larvae were structural abnonal and shaped like Apollo. In 10(-7) M of Hg exogastrula embryos were produced. 3. Threshold concentration of complete inhibition on the early development of sea urchin embryos was at 10(-6) M of Hg, 10(-5) M of Cu, Cr, Ni, and Zn, 10(-3) M of Mn. In the case of Cd 10(-5) M, complete inhibition didn't occur until the pluteus larva stage. 4. Only additive effects were obtained on the developing sea urchin eggs when two heavy metals were combined in filtered seawater. A high frequency of morphological abnormalities were formed such as exogastrula and Apollo shaped pluteus especially in coupling of Hg and Cu or Cd and Zn. 5. There were no visible effects in filtered sewage from fertilization to the formation of the pluteus larva. When embryos were exposed to acetate salts of Hg, Cu, Cd, and Zn in filtered sewage, there were 10 fold inhibitory effects on development. But formation of skeleton in the pluteus larva was found in filtered sewage containing Cd. 6. Only additive effects were observed on sea urchin embryo when combined with Hg, Cu, Cd, and Zn in filterd sewage. But the abnormalities were decreased in all cases. Inhibition of bonification were reduced in mixture of Cd and filtered sewage. en-copyright= kn-copyright= en-aut-name=MurakamiTetuhide en-aut-sei=Murakami en-aut-mei=Tetuhide kn-aut-name=村上哲英 kn-aut-sei=村上 kn-aut-mei=哲英 aut-affil-num=1 ORCID= en-aut-name=HayakawaMasashi en-aut-sei=Hayakawa en-aut-mei=Masashi kn-aut-name=早川昌志 kn-aut-sei=早川 kn-aut-mei=昌志 aut-affil-num=2 ORCID= en-aut-name=FujiiToshitake en-aut-sei=Fujii en-aut-mei=Toshitake kn-aut-name=藤井和武 kn-aut-sei=藤井 kn-aut-mei=和武 aut-affil-num=3 ORCID= en-aut-name=HaraTakehito en-aut-sei=Hara en-aut-mei=Takehito kn-aut-name=原武仁 kn-aut-sei=原 kn-aut-mei=武仁 aut-affil-num=4 ORCID= en-aut-name=ItamiYoshiaki en-aut-sei=Itami en-aut-mei=Yoshiaki kn-aut-name=伊丹義明 kn-aut-sei=伊丹 kn-aut-mei=義明 aut-affil-num=5 ORCID= en-aut-name=KishidaAkira en-aut-sei=Kishida en-aut-mei=Akira kn-aut-name=岸田昭 kn-aut-sei=岸田 kn-aut-mei=昭 aut-affil-num=6 ORCID= en-aut-name=NisidaIsamu en-aut-sei=Nisida en-aut-mei=Isamu kn-aut-name=西田勇 kn-aut-sei=西田 kn-aut-mei=勇 aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一生理学教室 affil-num=2 en-affil= kn-affil=岡山大学医学部第一生理学教室 affil-num=3 en-affil= kn-affil=岡山大学医学部第一生理学教室 affil-num=4 en-affil= kn-affil=岡山大学医学部第一生理学教室 affil-num=5 en-affil= kn-affil=岡山大学医学部第一生理学教室 affil-num=6 en-affil= kn-affil=岡山大学医学部第一生理学教室 affil-num=7 en-affil= kn-affil=岡山大学医学部第一生理学教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=5-6 article-no= start-page=689 end-page=695 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=19780630 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The mutual effects of N0(2) + Cd(2+) and N0(2) + Zn(2+) on the mitochondrial membrane. kn-title=ミトコンドリア膜に対する亜硝酸イオンとカドミウムイオン,亜鉛イオンの相互作用について en-subtitle= kn-subtitle= en-abstract= kn-abstract=The mutual effects of NaNO(2) + CdCl(2) and NaNO(2) + ZnCl(2) on the oxidative phosphorylation of rat liver mitochondria were examined and following results were obtained.

The results were as follows: An increase in AMP concentration was brought about by the addition of Cd(2+). This increase in AMP concentration occurred in parallel with increase in Cd(2+) concentration. The appearance of AMP was thought to be due to an ATPase reaction and an adenylate kinase reaction stimulated by Cd(2+) although further studies on the adenylate kinase reaction stimulated by Cd(2+) are needed. An increase in AMP may influence metabolism via glycolysis. As lanthanium (La(3+)) is related to Ca(2+)-binding sites, the effect of La(3+) on the K(+)-release of rat liver mitochondria induced by Cd(2+) was also studied. The results were: K(+)-release induced by Cd(2+) was inhibited by La(3+).

Various concentrations of cadmium chloride (2.5, 5.0, 10.0 mg/Kg) were given by intraperitoneal injection. Two hours after cadmium injection, the activity of liver and kidney mitochondrial oxidative phosphorylation had decreased, suggesting that cadmium uncoupled oxidative phosphorylation in liver and kidney mitochondria. A dose response relationship of cadmium uncoupling was observed in liver mitochondria, but was not observed in kidney mitochondria indicating that kidney mitochondria were more sensitive to cadmium than liver mitochondria were. A single injection of 250 mg/Kg of magnesium chloride prevented the uncoupling action of cadmium in liver mitochondria but not in kidney mitochondria. Magnesium did not prevent the uncoupling action of mercury chloride in liver or kidney mitochondria. The preventive action of magnesium chloride was evident in in vitro liver mitochondria but not in in vitro kidney mitochondria. The effect of magnesium on cadmium action was discussed. en-copyright= kn-copyright= en-aut-name=HasegawaTohoru en-aut-sei=Hasegawa en-aut-mei=Tohoru kn-aut-name=長谷川亨 kn-aut-sei=長谷川 kn-aut-mei=亨 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 en-keyword=カドミウム kn-keyword=カドミウム en-keyword=肝及び腎ミトコンドリア kn-keyword=肝及び腎ミトコンドリア en-keyword=酸化的リン酸化 kn-keyword=酸化的リン酸化 en-keyword=マグネシウム kn-keyword=マグネシウム END start-ver=1.4 cd-journal=joma no-vol=93 cd-vols= no-issue=11-12 article-no= start-page=1083 end-page=1090 dt-received= dt-revised= dt-accepted= dt-pub-year=1981 dt-pub=19811230 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Induction of metallothionein synthesis in the liver of rats by X-ray irradiation kn-title=X線照射によるラット肝メタロチオネインの誘導 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Experiments were carried out on the rat liver metallothionein induced by X-ray irradiation.

Eightly-eight human whole blood samples were taken from 20-59 year old normal adult subjects (57 males and 31 females) in Okayama Prefecture, and the heavy metal concentrations were mesured with a flame or flameless atomic absorption spectrophotometer. The order by level of heavy metals in the whole blood was Fe, Mg, Ca, Zn, Cu, Pb, Mn and Cd. The analytical values of each metal approximated a log-normal distribution. The levels of Fe, Mg and Zn were higher in males than in females, while that of Cu was higher in females high correlation coefficients were obtained between Pd-Cd, Pb-Cd, Cd-Mn and Cd-Fe. The levels of Fe and Zn in males had a negative correlation with thier age. On the other hand, that of Ca and Mg in females had a positive correlation. The heavy metal levels in the fethers of crows were examined as a biological index of heavy metal contamination. The order of heavy metals in feathers was: Zn, Fe, Mn, Pb, Hg and Cd. The concentrations of Pb and Mn were from 3 to 10 times higher in the feathers of crows than in human hair. The concentraiton levels of Cd and Cu were higher in the southern part than in the northern part of Okayama Prefecture. There were significant regional differences in the levels of Pb, Cd and Cu. The order of heavy metals in oyster was Zn, Cu, Mn, As, Ni, Cd, Pb, Se and Hg. The concentration of Zn and Cu had a significant correlation with the size of the oyster. The order of biological concentration was; Zn (22.3×10), Se, Cu, Mn, As, Ni and Pb (7.75×10(3)-0.22×10(3)) en-copyright= kn-copyright= en-aut-name=MoritaKeijiro en-aut-sei=Morita en-aut-mei=Keijiro kn-aut-name=森田啓次郎 kn-aut-sei=森田 kn-aut-mei=啓次郎 aut-affil-num=1 ORCID= en-aut-name=OgataMasana en-aut-sei=Ogata en-aut-mei=Masana kn-aut-name=緒方正名 kn-aut-sei=緒方 kn-aut-mei=正名 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部公衆衛生学教室 affil-num=2 en-affil= kn-affil=岡山大学医学部公衆衛生学教室 en-keyword=指標生物 kn-keyword=指標生物 en-keyword=生体中金属 kn-keyword=生体中金属 en-keyword=人血液 kn-keyword=人血液 en-keyword=カラス kn-keyword=カラス en-keyword=カキ kn-keyword=カキ END start-ver=1.4 cd-journal=joma no-vol=96 cd-vols= no-issue=3-4 article-no= start-page=327 end-page=339 dt-received= dt-revised= dt-accepted= dt-pub-year=1984 dt-pub=19840430 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on biochemical effects of manganese I; Atomospheric levels and phsicochemical properties of manganese in the enviroment kn-title=マンガンの生体影響に関する研究 第1編 溶接作業場及び居住地域におけるマンガンの性状と気中濃度 en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the present study, the author examined the physicochemical properties and the atomospheric levels of manganese and other heavy metals in the suspended particulate matter of a welding workshop and a residential area neighboring an iron works. α-Fe(2)O(3) and Fe(3)O(4) were the main components of the suspended particulate matter collected in the atomosphere around both areas. The total suspended particulate matter of the welding process (welding TSP) also contained MnFe(2)O(4) formed from Fe(3)O(4) by exchange of Fe with Mn, metalic Mn and an alloy from of Mn-Fe. These findings were obtained by X-ray diffractometry. Observation through the electron microscope showed the presence of fin particles (0.5-1.5μm) in welding TSP, and attention should be given hazards. The concentration of the metals in the welding TSP was about 10 to 30 times higher than that in the covering materials of the welding rods. Exposure levels of manganese in the welding workshop at a breathing zone ranged from 0.4 to 1.0μg/m(3) and the levels were reduced to one tenth by using a welding mask. Levels of manganese have decreased from a maximum median levels of 0.24μg/m(3) in 1971 to 0.15μg/m(3) in 1981. The order of content of the metals in the paticulate matter was: Fe, Cu, Zn, Pb, Mn, V, Ni, and Cd. en-copyright= kn-copyright= en-aut-name=MoritaKeijiro en-aut-sei=Morita en-aut-mei=Keijiro kn-aut-name=森田啓次郎 kn-aut-sei=森田 kn-aut-mei=啓次郎 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 en-keyword=マンガン気中濃度 kn-keyword=マンガン気中濃度 en-keyword=化学形態 kn-keyword=化学形態 en-keyword=粒径 kn-keyword=粒径 en-keyword=溶接作業場 kn-keyword=溶接作業場 en-keyword=居住地域 kn-keyword=居住地域 END start-ver=1.4 cd-journal=joma no-vol=99 cd-vols= no-issue=3-4 article-no= start-page=321 end-page=336 dt-received= dt-revised= dt-accepted= dt-pub-year=1987 dt-pub=19870430 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Serum and urinary β(2)-microglobulin levels of monkeys orally exposed to cadmium under malnutritional conditions kn-title=カドミウム経口投与サルの血清および尿β(2)ミクログロブリンの変動 ―栄養要因の影響― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Urinary and serum cadmium levels as well as cadmium contents in kidneys of female rhesus monkeys given a cadmium (Cd)-containing diet and subjected to malnutrition were slightly elevated during the experimental period of 7 years. Particulary, greater excretion of cadmium in urine, elevation of serum cadmium and greater accumlation of cadmium in kidneys were observed early in the malnutritional groups (groups No.6, 7 and 8) as compared to the basal diet group (group No.5). One monkey in the low-nutritional and low-vitamin D group fed with Cd (group No.8) accumulated over 1000μg of Cd per g wet weight in the kidneys even at 36 months. No remarkable changes in serum β(2)-microglobulin were observed in the Cd-treated groups (group No.5 to No.8) nor in the non-Cd treated groups (groups No.1 to No.4) during the experimental period. Although no significant leak of urinary β(2)-microglobulin was seen among the basal diet group fed with Cd (group No.5), the basal diet and low-vitamin D group fed with Cd (group No.7) and the non-Cd treated group (groups No.1 to No.4), much urinary β(2)-microglobulin began to leak at 36 months in the low-nutritional and low-vitamin D group fed with Cd (group No.8) and at 48 months in the low-nutritional group fed with Cd (group No.6). The high levels of urinary β(2)-microglobulin seen in group No.8 reverted to normal with medical treatment, and the high levels observed in group No.6 sometimes decreased. These observations suggest mild renal dysfunction among the malnutritioned monkeys (groups No.6 and No.8) exposed to Cd. en-copyright= kn-copyright= en-aut-name=OtakiNoriko en-aut-sei=Otaki en-aut-mei=Noriko kn-aut-name=小瀧規子 kn-aut-sei=小瀧 kn-aut-mei=規子 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 en-keyword=Cadmium kn-keyword=Cadmium en-keyword=Monkeys kn-keyword=Monkeys en-keyword=Serum and urinary Beta-2-Microglobulin kn-keyword=Serum and urinary Beta-2-Microglobulin END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=1 article-no= start-page=41 end-page=43 dt-received= dt-revised= dt-accepted= dt-pub-year=1973 dt-pub=19730720 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Effect of Temperature Gradient on Ultrasonic Attenuation en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effect of temperature gradient on ultrasonic attenuation is estimated based upon the simple phenomenological theory, and it being found that the attenuation coefficient for a CdS crystal is 0.76 dB/cm at temperature gradient 100 K/cm. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=IshiiTadao kn-aut-sei=Ishii kn-aut-mei=Tadao aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=Department of Electronics, Electrophysics END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=1 article-no= start-page=47 end-page=52 dt-received= dt-revised= dt-accepted= dt-pub-year=1971 dt-pub=19710901 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Solubility of Sulphur in a Cadmium Borate Glass and SomeProperties of the Sulphur Containing Glasses en-subtitle= kn-subtitle= en-abstract= kn-abstract=The glass forming limit by substitution of CdS for CdO in a CdO-B(2)0(3) glass was determined by chemical analysis. When x CdS-(60-x)CdO-40B(2)0(3) nominal mixtures in weight ratio were heated at 1100°C in flowing nitrogen gas for 1/2 hour, about 40~50% of mixed CdS and 10-15% of the mixed CdS were evaporated. The limit of nominal composition for glass forming was 10CdS-50CdO-40B(2)0(3) and the corresponding virtual composition after the above heat treatment was found to be 4.9CdS-46.4CdO-48.7B(2)O(3). Further addition of CdS made the melt devitrefied with CdS precipitation. D.C. conductivity measurements revealed that the current density was not linear with respect to the applied voltage, but the resistivity ranged around 10(12)Ω・cm for 4.1CdS-48.8CdO-47.1B(2)O(3) (virtual composition) glass and around 10(11.5)Ω·cm for 4.9CdS-46.4CdO-48.7B(2)O(3) glass. These sulphur containing glasses did not show photoconduction, although CdS-precipitated materials showed slight photoconductivity when disposed in ultra violet radiation. Apparent dielectric constant and tan 8 were also measured as a function of frequency, revealing a moderate dispersion in the CdS-precipitated glasses. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=TakahashiKatsuaki kn-aut-sei=Takahashi kn-aut-mei=Katsuaki aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=GotoYasumasa kn-aut-sei=Goto kn-aut-mei=Yasumasa aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Department of Industrial Chemistry affil-num=2 en-affil= kn-affil=Department of Industrial Chemistry END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=1 article-no= start-page=39 end-page=50 dt-received= dt-revised= dt-accepted= dt-pub-year=1968 dt-pub=19680901 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Binding Energy between a Vacancy and an Atom of Third Element and their Effects on the Initial Aging of Aluminium Binary Alloys en-subtitle= kn-subtitle= en-abstract= kn-abstract=Al-Zn, Al-Ag and Al-Cu base ternary alloys were studied by measurement of electrical resistivity. An approximate methods to estimate the binding energy between an atom of a third element and a vacancy was derived. The binding energy between a vacancy and an atom of Cu, Ag, Au, Be, Ca, Cd, In, Si, Ti, Ge, Zr, Sn, Pb or Mn was estimated to be <0.23, 0.25,> 0.35, 0.28, 0.27, 0.32, 0.39, 0.28, 0.30, 0.33, 0.33, 0.43, >0.38 or <0.23 (±0.05) eV, respectively. The results may be summarized as follows: (I) The ratio of the time required to reach the maximum electrical resistivity in isothermal aging curves of the Al-Zn-X or Al-Ag-X ternary alloy to that in the Al-Zn or Al-Ag binary alloy may be inversely proportional to the ratio of the concentration of vacancies bound to Zn or Ag atoms immediately after quenching in the ternary alloy to that in the binary alloy. And also the ratio of initial rate of clustering for AI-Cu-X ternary alloy to that in the binary alloy may be inversely proportional to the ratio of the concentration of vacancies bound to Cu atoms immediately after quenching in the ternary alloy to that in the binary alloy. It is possible to deduce the binding energy between an atom of X element and a vacancy using this relations. (2) The effect of the valence of the solute element on the binding energy between an atom of a third element and a vacancy was remarkable. (3) The effect of the radius of an atom of the solute element on the binding energy is also observed, but this effect is smaller than that of the valence. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=OhtaMatsuo kn-aut-sei=Ohta kn-aut-mei=Matsuo aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=HashimotoFumio kn-aut-sei=Hashimoto kn-aut-mei=Fumio aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=TanimotoTadashi kn-aut-sei=Tanimoto kn-aut-mei=Tadashi aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Department of Industrial Science affil-num=2 en-affil= kn-affil=Department of Industrial Science affil-num=3 en-affil= kn-affil=Department of Iudusttial Science END start-ver=1.4 cd-journal=joma no-vol=1 cd-vols= no-issue=1 article-no= start-page=138 end-page=147 dt-received= dt-revised= dt-accepted= dt-pub-year=1966 dt-pub=19660331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Binding Energies between a Vacancy and a Cadmium, Indium or Tin Atom in Al-10wt % Zn, Al-3.0wt % Ag and Al-3.0wt % Cu Alloys en-subtitle= kn-subtitle= en-abstract= kn-abstract=The changes of electrical resistivity of several alloys, that is, Al-10wt % Zn, Al-10wt % Zn-0.01wt % Cd, Al-10wt % Zn-0.01wt % In, Al-10wt % Zn-0.01wt % Sn, Al-3.0wt % Ag, Al-3.0wt % Ag-0.01wt % Cd, Al-3.0wt % Ag-0.01wt % In, Al3.0wt % Ag-0.0lwt % Sn, Al-3.0wt % Cu, Al-3.0wt % Cu-0.0lwt % Cd and Al-3.0wt % Cu-0.01wt % In, during isothermal aging after quenching were measured.

They have been known to bind to some serum lipoproteins and to form complexes. To elucidate whether each serum lipoprotein subclass could be separated by electrophoresis using CDs, we performed preliminary experiment, in which lipoprotein-CDs interaction was examined on electrophoresis with agarose gel. When the supporting agarose gel containing both α-CD and β-CD was prepared and was applied to isoelectric focusing for fractionating serum lipoproteins, apoB lipoproteins were found to be clearly separated into several fractions on this electrophoresis. This finding suggested that apoB lipoprotein may be detected as isolated form by arranging amounts of added CDs. en-copyright= kn-copyright= en-aut-name=IchimuraMitsuko en-aut-sei=Ichimura en-aut-mei=Mitsuko kn-aut-name=一村光子 kn-aut-sei=一村 kn-aut-mei=光子 aut-affil-num=1 ORCID= en-aut-name=TohgeHiroko en-aut-sei=Tohge en-aut-mei=Hiroko kn-aut-name=唐下博子 kn-aut-sei=唐下 kn-aut-mei=博子 aut-affil-num=2 ORCID= en-aut-name=SakiyamaJunko en-aut-sei=Sakiyama en-aut-mei=Junko kn-aut-name=崎山順子 kn-aut-sei=崎山 kn-aut-mei=順子 aut-affil-num=3 ORCID= en-aut-name=MoriShuji en-aut-sei=Mori en-aut-mei=Shuji kn-aut-name=森秀治 kn-aut-sei=森 kn-aut-mei=秀治 aut-affil-num=4 ORCID= en-aut-name=ItoSekiko en-aut-sei=Ito en-aut-mei=Sekiko kn-aut-name=伊藤昔子 kn-aut-sei=伊藤 kn-aut-mei=昔子 aut-affil-num=5 ORCID= en-aut-name=NakataYasunari en-aut-sei=Nakata en-aut-mei=Yasunari kn-aut-name=中田安成 kn-aut-sei=中田 kn-aut-mei=安成 aut-affil-num=6 ORCID= en-aut-name=EndoHiroshi en-aut-sei=Endo en-aut-mei=Hiroshi kn-aut-name=遠藤浩 kn-aut-sei=遠藤 kn-aut-mei=浩 aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医療技術短期大学部衛生技術学科 affil-num=2 en-affil= kn-affil=岡山大学医療技術短期大学部衛生技術学科 affil-num=3 en-affil= kn-affil=岡山大学医療技術短期大学部衛生技術学科 affil-num=4 en-affil= kn-affil=岡山大学医療技術短期大学部衛生技術学科 affil-num=5 en-affil= kn-affil=岡山大学医療技術短期大学部衛生技術学科 affil-num=6 en-affil= kn-affil=岡山大学医療技術短期大学部衛生技術学科 affil-num=7 en-affil= kn-affil=岡山大学医療技術短期大学部衛生技術学科 en-keyword=血清apoB含有リポタンパク質 (serum apoB lipoprotein) kn-keyword=血清apoB含有リポタンパク質 (serum apoB lipoprotein) en-keyword=シクロデキストリン (cyclodextrin) kn-keyword=シクロデキストリン (cyclodextrin) en-keyword=等電点電気泳動 (isoelectric focusing (IEF)) kn-keyword=等電点電気泳動 (isoelectric focusing (IEF)) en-keyword=agarose gel kn-keyword=agarose gel END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue= article-no= start-page=75 end-page=78 dt-received= dt-revised= dt-accepted= dt-pub-year=1996 dt-pub=199611 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Gastro-biliary motility in patients with non-ulcer dyspepsia kn-title=上腹部不定愁訴患者の胃・胆嚢運動に関する研究 en-subtitle= kn-subtitle= en-abstract=Subjective symptoms are quite similar between cystic duct syndrome (CDS) and non-ulcer dyspepsia (NUD) : epigastralgia, hypochondralgia and vague complaints in the upper part of the abdomen. Recently, there has been several reports suggesting that the cause of these disorders is postprandial dysmotility in the gallbladder and stomach. However, there has been no report suggesting incoordination of postprandial gastrobilialy motility as the cause of tha above mentioned complaints in these disorders. The aim of this study was to define the difference of postprandial gastrobiliary motility between patients with NUD and controls. Eight patients with NUD and 10 controls were studied. Gastric emptying time of liquid meal and gallbladder contraction were measured, simultaneously. There was no significant difference between study patients and controls when gastric emptying time and gallbladder contraction rate were compared in isolation. However, when these two parameters were assessed in combination, gastric emptying time was linearly correlated with minimum ballbladder contraction time in controls but not in patients. We conclude that the incoordination between gastric emptying and minimal gallbladder contraction may be one of the major causes of the symptoms in NUD.

elements in natural water samples were determined simultaneously by air-segmented flow-injection/inductively coupled plasma-mass spectrometry(SFI/ICP-MS).A small volume of the sample solutions(80μl) was introduced into a nebulizer by an air-segmented flow-injection(SFI) system, and a maximum of fifteen elements were measured during each run.A chitosan-based chelating resin containing functional groups of iminodiacetate was used to separate and enrich analyte metal ions.A 50-fold preconcentration using 50ml of sample solutions was achieved by the proposed method, where 1ml of 0.1M nitric acid was added to residues after drying the chelating column effluent.At pH6, several heavy metals(Fe, Ni, Co, Cu, Zn, Ag, Cd, Pb and U) and rare earth elements(REEs) were quantitatively retained on the chelating resin column, whereas alkali and alkaline earth metals were eluted from the column by rinsing with 5ml of a 0.2M ammonium acetate solution.Metals adsorbed on the chelating resin column were recovered by elution with 10ml of 1M nitric acid.The proposed method was applied to the determination of trace elements in several natural water samples, such as river water and mineral drinking

A dual-task experimemt was conducted in which the primary task was first-irder tracking. The secondary tasks included control of an air conditioner, the operation of a radio, and the operation of a CD/MD, by means of a steering wheel mounted swich. The switch was either vertical or cross arrangement. In both-hands switch arrangement condition, the operation was carried out with two hands using both left vertical switch and right cross switch. In one-hand swith arrangement condition, the operation was carried out with only one hand using either left or right cross switch. The display was arranged in front of a participant. The display form was either left or right display. The viewing distance conditions were 60, 80, and 100cm. When the right display form was used, both one-hand (using only right cross switch) were selected. When the left display form was used, both one-hand (using only left cross swith) and two-hand arrangements (using both left vertical and right cross switch) were selected. As predicted, age affected the performance measures ( percentage correct, task completion time, and tracking error). The viewing distance also affected performance (percentage correct), Both display form and switch arrangement also affected performance (task completion time). Such results should be taken into account when designing display and control systems in man-vehicle systems. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=YamaguchiSatoshi en-aut-sei=Yamaguchi en-aut-mei=Satoshi kn-aut-name=山口智司 kn-aut-sei=山口 kn-aut-mei=智司 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=2008 cd-vols= no-issue=1 article-no= start-page=83 end-page=88 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=200812 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of Automotive Control-Display System by means of MentalWorkload en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effects of age, task difficulty on performance and mental workload were discussed in order to provide design guideline of automobile display that is friendly to older adults from the viewpoints of mental attention, speed and accuracy. A dual-task experiment was conducted in which the primary task was first order tracking. The secondary tasks included selection of function (easy condition), and control of an air conditioner, the operation of a radio, and the operation of a CD/MD (difficult condition), by means of a steering wheel mounted switch. The display was arranged in front of a participant. Age affected the performance measures and heart rate variability (HRV). As for the young adults, the task completion time did not differ significantly among easy and difficult (one-, two-, and three-layered) conditions. The performance of older adults was affected by task difficulty. The HRV measures such as CV (coefficient of variance) and RRV8-3 during the task showed different tendency between young and older adults. As for the young group, the HRV measures did not differ significantly between the four task levels (easy, one-, two-, and three-layered). This confirmed that the task difficulty did not induce different mental workload to young adults. On the other hand, as for the older adults, the HRV measures tended to increase with the increase of task difficulty. Although it appears that mental workload was lessened with the increase of task difficulty, such an interpretation was contradictory to the results on performance. This phenomenon was interpreted that the difficult task condition was overloaded for older adults, and was beyond the limit of mental effort. Based on the results, it could be concluded that the difficult task condition is not proper for older adults. en-copyright= kn-copyright= en-aut-name=MurataAtsuo en-aut-sei=Murata en-aut-mei=Atsuo kn-aut-name=村田厚生 kn-aut-sei=村田 kn-aut-mei=厚生 aut-affil-num=1 ORCID= en-aut-name=MoriwakaMakoto en-aut-sei=Moriwaka en-aut-mei=Makoto kn-aut-name=森若誠 kn-aut-sei=森若 kn-aut-mei=誠 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=11-12 article-no= start-page=1301 end-page=1310 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on chemotherapy for small cell lung cancer Part 1.

SBC-3/ADM was not circumvented by hyperthermia of 42℃ or amphotericin B at a concentration of 50μ M. Verapamil did not enhance the adriamycin cytoxicity in the SBC-3 cells at a concentration of 10μ M, but a 3.2-fold increase in the drug effect occurred in the SBC-3/ADM cells in terms of LD(70). The efflux of intracellular [H(3)] daunomycin from SBC-3/ADM cells was inhibited by verapamil, while the inhibition did not occur in the parent cells. Furthermore, quinidine (50μ M), cepharanthin (10μ M) and chloroquine (50μ M) enhanced the adriamycin cytotoxicity in the SBC-3/ADM cells. These findings suggest that some membrane-modifying agents could partially overcome the acquired resistance to adriamycin in human small cell lung cancer. en-copyright= kn-copyright= en-aut-name=YamashitaHidetoshi en-aut-sei=Yamashita en-aut-mei=Hidetoshi kn-aut-name=山下英敏 kn-aut-sei=山下 kn-aut-mei=英敏 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=human small cell lung cancer cells in culture kn-keyword=human small cell lung cancer cells in culture en-keyword=ADM resistant subline kn-keyword=ADM resistant subline en-keyword=reversal of resistance kn-keyword=reversal of resistance END start-ver=1.4 cd-journal=joma no-vol=102 cd-vols= no-issue=1-2 article-no= start-page=209 end-page=216 dt-received= dt-revised= dt-accepted= dt-pub-year=1990 dt-pub=199002 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Amplification and expression of myc-related oncogenes n adenovirus-induced tumors kn-title=アデノウイルス誘発マウス腫瘍における myc 群癌遺伝子の増幅と発現 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Amplification and expression of myc-related oncogenes were studied on adenovirus-induced tumors (D and IC) and spontaneous hapatoma (P), all of which had been successively trans-planted in C3Hf/OK mice. c-myc expression waas elevated in the D, IC anf P tumors, and a 8.9-fold amplification of c-myc was observed in the IC tumor. In the D tumor N-myc expression was elevated and a 1.9-fold amplification of N-myc was also observed. Amplification of c-myc in the IC tumor was suspected to be a result of selection for c-myc amplified cells during successive transplantation.

Rats treated with haloperidol showed an increase in striatal D-2 receptor binding as revealed by [(3)H] spiperone. Striatal D-1 receptos labeled with [(3)H] SCH 23390 were not changed following treatment with haloperidol in young rats for 2 weeks, while, it was decreased following 85 weeks of tretment. The striatal D-1 receptors were decreased also after a 4 week treatment with haloperidot in aged rats. These results suggest that haloperidol treatment in the aged rats results in D-2 receptor supersensitivity and a decline in D-1 receptors. Such relative supersensitivity of the D-2 receptor over the D-1 receptor may be related to the vulnerability to tardive dyskinesia of the aged. en-copyright= kn-copyright= en-aut-name=NishikawaHiroshi en-aut-sei=Nishikawa en-aut-mei=Hiroshi kn-aut-name=西川浩 kn-aut-sei=西川 kn-aut-mei=浩 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部神経精神医学教室 en-keyword=dopamine receptors kn-keyword=dopamine receptors en-keyword=haloperidol kn-keyword=haloperidol en-keyword=aging kn-keyword=aging en-keyword=striatum kn-keyword=striatum en-keyword=tardive dyskinesia kn-keyword=tardive dyskinesia END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=5-6 article-no= start-page=505 end-page=515 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Zinc metabolism in the endotoxin-treated rats kn-title=エンドトキシンが体内亜鉛代謝に及ぼす影響に関する実験的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effect of endotoxin administration on zinc metabolism was studied in rats. In the endotoxin-treated rats, serum zinc concentration was significantly reduced as compared to saline-treated rats (control group). On the other hand, hepatic zinc concentration was significantly increased after endotoxin administration as compared to the control group. However, the zinc concentrations of the liver cell components showed slightly dissimilarity. In the mitochondria and cytsol, the concentration increased significantly after endotoxin administration as compared to the control group, whereas no change was observed in the microsomes. Furthermore, we have examined whether the increase of the zinc level in the cytosol of the liver is associated with zinc-binding protein metallothioneins (MTs) or not. MTs also increased significantly after endotoxin administration. Furthermore hepatic MTs were analyzed for MT isoforms. In the endotoxin-treated MT-II was the major Iso-MT. Judging from these results and some other published reports, the role of zinc metabolism in endotoxemia is proposed to be as follows. In endotoxemia the serum zinc concentration is reduced and as a result the production of superoxide by polymorphonuclear leukocytes is increased as zinc has an inhibitory effect on it. This free radical helps the host against the organism. On the other hand zinc accumulation in the liver following endotoxin administration increases the activity of the zinc binding-enzyme and also stabilizes the plasma membrane. MTs induced by endotoxin protect the host from the harmful effects of the free radical in the host by its scavenging action. en-copyright= kn-copyright= en-aut-name=MatsumiMasaki en-aut-sei=Matsumi en-aut-mei=Masaki kn-aut-name=松三昌樹 kn-aut-sei=松三 kn-aut-mei=昌樹 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=エンドトキシン kn-keyword=エンドトキシン en-keyword=亜鉛 kn-keyword=亜鉛 en-keyword=メタロチオネイン kn-keyword=メタロチオネイン END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=5-6 article-no= start-page=701 end-page=711 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the pathogenesis of interstitial pneumonia of collagen vascular diseases Part 2.

IL-2 and IL-2 receptors play important roles as immunological regulation in CVD. In this study, the soluble forms of IL-2 receptor (sIL-2R) and IL-2 receptor positive lymphocytes (CD25) were analyzed to evaluate the role of IL-2R in the pathogenesis of interstitial pneumonia (IP) of CVD such as RA, SLE, polymyositis/dermatomyositis (PM/DM), and PSS and idiopathic interstitial pneumonia (IIP) as a disease control. High levels of sIL-2R were found in sera of patients with IP of CVD. The level of soluble IL-2R in sera of RA without IP correlated with the disease activity of the joints, while the level of sIL-2R in sera of RA with IP was higher than in that of RA without IP. Soluble IL-2R in bronchoalveolar lavage fluind (BALF) was also measured and the level was higher in IP with CVD. There were fewer IL-2R positive lymphocytes in the peripheral blood of CVD with IP than in the normal controls or IIP cases, although the serum level of sIL-2R was higher in CVD with IP and IIP than in the normal controls. These findings indicate that actibve immunological activities involving IL-2/IL-2R/sIL-2R systems play an important role in the pathogenesis of IP of CVD. en-copyright= kn-copyright= en-aut-name=YokotaSatoshi en-aut-sei=Yokota en-aut-mei=Satoshi kn-aut-name=横田聡 kn-aut-sei=横田 kn-aut-mei=聡 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=collagen vascular disease kn-keyword=collagen vascular disease en-keyword=interstitial pneumonia kn-keyword=interstitial pneumonia en-keyword=bronchoalveolar lavage kn-keyword=bronchoalveolar lavage en-keyword=soluble IL-2 receptor kn-keyword=soluble IL-2 receptor en-keyword=IL-2 receptor positive lymphocyte kn-keyword=IL-2 receptor positive lymphocyte END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=4 article-no= start-page=281 end-page=292 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Pharmacological specificity of antipsychotic, antiischemic and some other drugs for σ receptors labeled with [(3)H] haloperidol kn-title=ラット脳内 σ 受容体の薬理学的特異性に関する研究―とくに抗精神病薬との抗虚血剤の作用について― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pharmacological specificity of several classes of drugs such as antipsychotics and antiischemic agents was assessed for σ receptors labeled with [(3)H] haloperidol. Specific binding of [(3)H] haloperidol in the presence of 25 nM spiperone was saturable and high affinity )Kd=1.96±1.31 nM, Bmax=2.37±0.27pmol/mg of protein;n=8). Among the 29 antipsychotics tested in inhibition studies, bromperidol and haloperidol were the most potent inhibitors (Ki=0.9nM, 1.0nM, respectively). The conventional antipsychotics moperone, timiperone etc. and the novel promising drugs YM-09151, Y-516, BMY-14802 and remoxipride potently inhibited [(3)H] haloperidol binding with the Ki in the range of low to moderate nanomolar. On the other hand, among the other 27 drugs tested, the antispasmodics eperisone and tolperisone, the antiischemic agents ifenprodil, the Ca(2+) antagonist flunarizine and cinnarizine, and the antitussives carbetapentane, cloperastine and dextromethorphan, were especially potent inhibitors. These results, taken together with the evidence that the antiischemic agents ifenprodil and dextromethorphan antagozine NMDA responses and NMDA receptor complex is a possible site of action for neuroprotective agents, strongly suggest that σ receptors may be potential sites of action for antiischemic as well as antipsychotic drugs, i.e., σ receptors mediate the neuroprotective effects of certain antiischemic agents by affecting the NMDA receptor complex. en-copyright= kn-copyright= en-aut-name=ZushiYoshifumi en-aut-sei=Zushi en-aut-mei=Yoshifumi kn-aut-name=図子義文 kn-aut-sei=図子 kn-aut-mei=義文 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部神経精神医学教室 en-keyword=sigma receptors kn-keyword=sigma receptors en-keyword=antipsychotics kn-keyword=antipsychotics en-keyword=ifenprodil kn-keyword=ifenprodil en-keyword=dextromethorophan kn-keyword=dextromethorophan en-keyword=eperisone kn-keyword=eperisone END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=5-6 article-no= start-page=625 end-page=637 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Metallothionein gene expression in rat liver following intraperitonal endotoxin administration kn-title=エンドトキシン投与ラットにおける肝内メタロチオネイン遺伝子発現に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To clarify the functions of hepatic metallothioneins (MTs) after the administration of endotoxin (lipopolysaccharide : LPS), we investigated the expression on MT genes in the bacterial endoxin-treated rat liver by Norhern blot hybridization and in situ hybridization methol with riboprobes synthesized from mouse cDNA of MT-Ⅱ chronologically. Northern blot analysis revealed a rapid increase in the amount of MT gene transcripts in the liver 3 hours after the administration of LPS, with a maximum at 6 to 12 hours followed by a gradual decrease. In the in situ hybridization method, MT genes are expressed in the liver lobule for 3 hours after the adiminstration of LPS, and hepatocellular damage was observed at 6 hours after the LPS administration initially and expanded most extensively at 18 hours. During this peripd, MT genes are expressed in intact tissue intensely and specifically. At 24 hours after the administration, transcripts of the MT gene were detected in intact hepatocytes around the shrinking necrotic area. These findings suggest that MTs protect the liver cells by scavenging the free radicals, which probably cause liver cell damage due to LPS administration, and that MTs provide the zinc ions necessary for stabilizing the cell membrane and to heal the liver cell damge. en-copyright= kn-copyright= en-aut-name=TagaNaoyuki en-aut-sei=Taga en-aut-mei=Naoyuki kn-aut-name=多賀直行 kn-aut-sei=多賀 kn-aut-mei=直行 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=エンドトキンショック kn-keyword=エンドトキンショック en-keyword=メタロチオネイン kn-keyword=メタロチオネイン en-keyword=in situ hybridization kn-keyword=in situ hybridization END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=1-2 article-no= start-page=183 end-page=197 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Experimental study on pathogenesis and treatment of cerebral vasospasm Part 2.

The experiment was performed three days (72 hours) after artificial subarachnoid hemorrhage. The basilar artery was exposed transclivally, and more advanced vasospasm was produced by topical application of a lysed erythrocyte solution for 5 to 6 hours which domonstrated no more vascular dilatation even by topical application of papaverine hydrochloride (0.01mg/ml). In the delayed spasm model, the intravenous administration of neither OP-41483 (8μg/kg), OKY-046 (60mg/kg) nor nifedipine (0.003mg/kg) affected the vascular diameter. OP-41483 increased r-CBF in the brain stem in 3, and nifedipine increased it in 4 out of the 5 studied delayed spasm models, whereas OKY-046 never increased r-CBF (n=5). There was no significant difference in the amount of fatty acids including arachidonic acid between normal and constricted arteries. This study suggested that thromboxane A2 is not the major factor of cerebral vasospasm and OKY-046 might not be effective on vascular diameter or r-CBF at the late spasm stage. However, the PGI2 analogue (OP-41483) and Ca blocker (nifedipine) may be effective in increasing r-CBF even at the late spasm stage. en-copyright= kn-copyright= en-aut-name=MotokiMototsugu en-aut-sei=Motoki en-aut-mei=Mototsugu kn-aut-name=元木基嗣 kn-aut-sei=元木 kn-aut-mei=基嗣 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部脳神経外科教室 en-keyword=cerebral vasospasm kn-keyword=cerebral vasospasm en-keyword=thromboxane A2 kn-keyword=thromboxane A2 en-keyword=OP-41483 kn-keyword=OP-41483 en-keyword=OKY-046 kn-keyword=OKY-046 en-keyword=nifedipine kn-keyword=nifedipine END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=1-2 article-no= start-page=161 end-page=171 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The accumulation of metallothionein in the rat kidney injured by temporal ischemia kn-title=虚血性腎傷害による亜鉛代謝と腎内メタロチオネインの変動に関する実験的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The renal and hepatic metallothionein (MT) and serum zinc levels were studied in rats following renal ischemia, to clarify the effects of renal damage on the zinc metabolism.

The accumulation of hepatic MT was stimulated by sham operation and was augmented furthermore by renal ischemic damage. The renal MT level increased gradually and reached the maximum on the 3rd day in the bilateral renal ischemic rat. The MT level in the injured kidney was higher than that in the intact kidney in the unilateral renal ischemic rat. These results suggested that the mechanism of MT synthesis in the kidney was different from that in the liver, and that some local factor might induce MT in the injured kidney. en-copyright= kn-copyright= en-aut-name=MizukawaShun-ichi en-aut-sei=Mizukawa en-aut-mei=Shun-ichi kn-aut-name=水川俊一 kn-aut-sei=水川 kn-aut-mei=俊一 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=亜鉛 kn-keyword=亜鉛 en-keyword=虚血性急性腎不全 kn-keyword=虚血性急性腎不全 en-keyword=メタロチオネイン kn-keyword=メタロチオネイン END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=1-2 article-no= start-page=147 end-page=159 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Neurophysiological study of deep brain stimulation for the treatment of deafferentation pain Part 2.

As a preliminary experiment, the relationship between the waveform of the SEP and the anatomical structure of the brain was examined in cats. The infraorbital nerve was stimulated and the SEP was recorede around the VPM. From the rostral edge of the medial leminiscus (ML), a high voltage positive wave was recorded, and from the ventral side of the VPM a wide negative wave with positive wavelets was recorded. For the treatment of three cases of thalamic pain, the deep cerebral SEP was recorded during the insertion of a chronic electrode for deep brain stimulation. By contralateral median nerve stimulation, the high voltage posotive waves (peak latency ; 13-15msec) from the ML and the subsequent unerven waves from the VPL were recorded along the trajectory. The later uneven waves were composed of wide negative waves and positive wavelets, which were thought to be derived from the synaptic activity of the VPL and thalamocortical rediation, respectively. Effective pain relief was obtained at the border zone of the ventral VPL and the ML, where the characteristic waves of the VPL changed to those of the ML. The deep cerebral SEP can be used for the identification of target points electrophysiologically. en-copyright= kn-copyright= en-aut-name=TomitaSusumu en-aut-sei=Tomita en-aut-mei=Susumu kn-aut-name=富田享 kn-aut-sei=富田 kn-aut-mei=享 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部脳神経外科学教室 en-keyword=deafferentation pain kn-keyword=deafferentation pain en-keyword=deep brain stimulation kn-keyword=deep brain stimulation en-keyword=sensory evoked potential kn-keyword=sensory evoked potential en-keyword=leminiscus medialis kn-keyword=leminiscus medialis en-keyword=nucleus ventrocaudalis kn-keyword=nucleus ventrocaudalis END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=1-2 article-no= start-page=117 end-page=127 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Metallothionein gene expression in rat brain following intraperitoneal endotoxin administration kn-title=エンドトキシンによるラット脳内メタロチオネイン遺伝子発現に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To clarify the acute-phase response in brain, we investigated the induction of metallothionein (MT) genes by administering an endotoxin (lipopolysaccharide) in rat intraperitoneum. We performed in situ hybridization on the serial brain sections to identify the cells expressing the MT genes in the acute-phase. After endotoxin administration, transcripts of MT genes were detected in the arachnoideal, ependymal cells and the Bergmann glia of the cerebellum, while no significant induction of the MT genes by zinc ion was observed in the brain. These results suggest that the acute-phase response occurs specifically in at least these three non-neuronal cells. en-copyright= kn-copyright= en-aut-name=ItanoYoshitaro en-aut-sei=Itano en-aut-mei=Yoshitaro kn-aut-name=板野義太郎 kn-aut-sei=板野 kn-aut-mei=義太郎 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=メタロチオネイン kn-keyword=メタロチオネイン en-keyword=エンドトキシン kn-keyword=エンドトキシン en-keyword=脳 kn-keyword=脳 en-keyword=acute-phase kn-keyword=acute-phase en-keyword=in situ hybridization kn-keyword=in situ hybridization END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=5-6 article-no= start-page=489 end-page=499 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The usefulness of transvaginal ultrasonography and MRI in endometrial carcinama : Evaluating myomertrial and cervical invasion kn-title=子宮体癌に対する経腟走査超音波断層法とMRIの有用性について―筋層浸潤と頚部浸潤の評価― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Between October, 1988 and March, 1991, twenty-mine patients with endometrial carcinoma bad both transvaginal ultrasonography (TVUS) and magnetic resonance imaging (MRI) performed following hysterectomy at the Departmetn of Gynecology and Obstetrics, Okayama University Medical School. The findings were compared with the pathological findings to determine the usefulness of each method. The sensitivity of dectecthing myometrial invasion was 100% by TVUS and 96% by MRI. The accuracy was 86% by each method. The depth of myometrial invasion was classified into 3 degrees [no myometrial invasion, superficial invasion (≤1/2), deep invasion (>1/2)]. The correct diagnostic rate was 86% by TVUS and MRI. The minimum width and the minimum/maximum width ratio of the intact myometrium obtained by each method in the pathological deep invasion group were significantly lower than those obtained in the other two groups (p<0.01). The sensitivity, the accuracy and the specificity of detecting cervical invasion were 89%, 93% and 95% by both methods. There was no difference between TVUS and MRI for diagnosing myometrial and cerical invasion of endometrial carcinoma. en-copyright= kn-copyright= en-aut-name=YoshiharaEisuke en-aut-sei=Yoshihara en-aut-mei=Eisuke kn-aut-name=吉原英介 kn-aut-sei=吉原 kn-aut-mei=英介 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部産科婦人科学教室 en-keyword=子宮体癌 kn-keyword=子宮体癌 en-keyword=経腟走査超音波断層法 kn-keyword=経腟走査超音波断層法 en-keyword=MRI kn-keyword=MRI en-keyword=筋層浸潤 kn-keyword=筋層浸潤 en-keyword=頚部浸潤 kn-keyword=頚部浸潤 END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=1013 end-page=1018 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Lymph node metastases of right colon cancer kn-title=右側結腸癌に対するリンパ節郭清範囲の検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The lymph node metastases of the right side colon were studied.

Metastases to the intermediate nodes were found in 20.7% and metastases to the main nodes in 15.5%. Jumping metastases were recognized in 5 out of 31 cases of nodal involvement (16.1%). As the rate of jumping metastases is unexpectedly high, lymph node dissection for right colon cancer should be done as far as the main nodes. en-copyright= kn-copyright= en-aut-name=IwagakiHiromi en-aut-sei=Iwagaki en-aut-mei=Hiromi kn-aut-name=岩垣博巳 kn-aut-sei=岩垣 kn-aut-mei=博巳 aut-affil-num=1 ORCID= en-aut-name=HizutaAkio en-aut-sei=Hizuta en-aut-mei=Akio kn-aut-name=日伝晶夫 kn-aut-sei=日伝 kn-aut-mei=晶夫 aut-affil-num=2 ORCID= en-aut-name=HamadaFumihiro en-aut-sei=Hamada en-aut-mei=Fumihiro kn-aut-name=浜田史洋 kn-aut-sei=浜田 kn-aut-mei=史洋 aut-affil-num=3 ORCID= en-aut-name=ShiikiShigeo en-aut-sei=Shiiki en-aut-mei=Shigeo kn-aut-name=椎木滋雄 kn-aut-sei=椎木 kn-aut-mei=滋雄 aut-affil-num=4 ORCID= en-aut-name=MatsubaraNagahide en-aut-sei=Matsubara en-aut-mei=Nagahide kn-aut-name=松原長秀 kn-aut-sei=松原 kn-aut-mei=長秀 aut-affil-num=5 ORCID= en-aut-name=AkazaiYoshihiro en-aut-sei=Akazai en-aut-mei=Yoshihiro kn-aut-name=赤在義浩 kn-aut-sei=赤在 kn-aut-mei=義浩 aut-affil-num=6 ORCID= en-aut-name=SuzakiKiichi en-aut-sei=Suzaki en-aut-mei=Kiichi kn-aut-name=須崎紀一 kn-aut-sei=須崎 kn-aut-mei=紀一 aut-affil-num=7 ORCID= en-aut-name=WatanabeTetsuya en-aut-sei=Watanabe en-aut-mei=Tetsuya kn-aut-name=渡辺哲也 kn-aut-sei=渡辺 kn-aut-mei=哲也 aut-affil-num=8 ORCID= en-aut-name=NonakaYasuyuki en-aut-sei=Nonaka en-aut-mei=Yasuyuki kn-aut-name=野中泰幸 kn-aut-sei=野中 kn-aut-mei=泰幸 aut-affil-num=9 ORCID= en-aut-name=KimuraToshikazu en-aut-sei=Kimura en-aut-mei=Toshikazu kn-aut-name=木村臣一 kn-aut-sei=木村 kn-aut-mei=臣一 aut-affil-num=10 ORCID= en-aut-name=FuchimotoSadanori en-aut-sei=Fuchimoto en-aut-mei=Sadanori kn-aut-name=淵本定儀 kn-aut-sei=淵本 kn-aut-mei=定儀 aut-affil-num=11 ORCID= en-aut-name=OritaKunzo en-aut-sei=Orita en-aut-mei=Kunzo kn-aut-name=折田薫三 kn-aut-sei=折田 kn-aut-mei=薫三 aut-affil-num=12 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一外科学教室 affil-num=2 en-affil= kn-affil=岡山大学医学部第一外科学教室 affil-num=3 en-affil= kn-affil=岡山大学医学部第一外科学教室 affil-num=4 en-affil= kn-affil=岡山大学医学部第一外科学教室 affil-num=5 en-affil= kn-affil=岡山大学医学部第一外科学教室 affil-num=6 en-affil= kn-affil=岡山大学医学部第一外科学教室 affil-num=7 en-affil= kn-affil=岡山大学医学部第一外科学教室 affil-num=8 en-affil= kn-affil=岡山大学医学部第一外科学教室 affil-num=9 en-affil= kn-affil=岡山大学医学部第一外科学教室 affil-num=10 en-affil= kn-affil=岡山大学医学部第一外科学教室 affil-num=11 en-affil= kn-affil=岡山大学医学部第一外科学教室 affil-num=12 en-affil= kn-affil=岡山大学医学部第一外科学教室 en-keyword=右側結腸癌 kn-keyword=右側結腸癌 en-keyword=リンパ節転移率 kn-keyword=リンパ節転移率 en-keyword=跳躍転移 kn-keyword=跳躍転移 END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=5-6 article-no= start-page=457 end-page=469 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Metallothionein induction in the rat kidneys by endotoxin and zinc administration kn-title=エンドトキシンおよび亜鉛投与ラットにおける腎メタロチオネインの誘導に関する実験的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Metallothionein (MT) induction in the rat kidneys by endotoxin and zinc was investigated at the MT-protein level and the MT-mRNA level. The MT-mRNA level increased 3-6 hr after endotoxin administration, which suggested that MT was not transported from an other organ, but was de novo synthesized. Two MT-protein isoforms, MT-Ⅰ and MT-Ⅱ, were induced by administration of both endotoxin and zinc. The maximum levels of the proteins were seen 9 hr after administration of endotoxin and zinc. The span life of the renal MT induced by zinc was shorter than that of the liver MT induced by zinc. The MT-Ⅱ isoform was predominantly induced by both inducers, endotoxin and zinc, and the ratios of MT-Ⅱ to MT-Ⅰ were relatively constant. The finding that MT-Ⅰ and MT-Ⅱ were almost equally induced by zinc in the liver indicate that MT induction is controlled by an organ-specific system. en-copyright= kn-copyright= en-aut-name=KanaiYoshizumi en-aut-sei=Kanai en-aut-mei=Yoshizumi kn-aut-name=金居義純 kn-aut-sei=金居 kn-aut-mei=義純 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=エンドトキシン kn-keyword=エンドトキシン en-keyword=亜鉛 kn-keyword=亜鉛 en-keyword=腎メタロチオネイン kn-keyword=腎メタロチオネイン en-keyword=高速液体クロマトグラフィー kn-keyword=高速液体クロマトグラフィー END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=3-4 article-no= start-page=413 end-page=423 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studis on the pathogenesis of idiopathic interstitial pneumonia Part 1.

The BAL fluid of the patients with IIP and IP with CD in active stage contained a higher proportion of lymphocyte, neutrophil, eosinophil and basophil/mast cell than those in a nonactive stage. Furthermore, an increase of T-cells and Ia positive T-cells was detected in the examination of lymphocyte subpopulation in BAL fluid of patients with IIP, while the lymphocyte subpopulation of peripheral blood showed no significant difference. Cellular components in BAL fluid of IIP patients treated with or without steroids were compared. Under steroid therapy a decrease of total cell count and eosinophil was shown in BAL fluids of patients with IIP. These findings indicate that various cells such as macrophage, lymphocyte, neutrophil eosinophil and basophil/mast cell in lungs play important roles in the pathogenesis of IIP and IP with CD. en-copyright= kn-copyright= en-aut-name=FujitaMichio en-aut-sei=Fujita en-aut-mei=Michio kn-aut-name=藤田道雄 kn-aut-sei=藤田 kn-aut-mei=道雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=Idiopathic interstitial pneumonia kn-keyword=Idiopathic interstitial pneumonia en-keyword=Bronchoalveolar lavage kn-keyword=Bronchoalveolar lavage en-keyword=Lymphocyte subpopulation kn-keyword=Lymphocyte subpopulation END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=3-4 article-no= start-page=247 end-page=258 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Experimental and clinical studies on interferon and its inducers Part 1.

The base lines (BLs), peak levels (PLs) and times to PLs (PLs) of neutrophil ChL were examined before, one week and one month after the treatment. The direct effects of IFN-α, Ge-132 and OK-432 on neutrophil ChL were also evaluated by using an in vitro experimental system. PLs were significantly increased one week after the treatment with IFN-α or Ge-132. However, they were decreased to the pretreatment level one month after the treatment. In vitro experimental system IFN-α enhanced PLs of neutrophil ChL showing dose and time dependencies. On the other hand Ge-132 and OK-432 showed no direct effect on neutrophil ChL in vitro. These findings suggest that IFN-α and Ge-132 enhance the host defense mechanism by the activation of neutrophil functions, and also suggest that they have some benefits not only in the clinical management of cancer but also of chronic infection. en-copyright= kn-copyright= en-aut-name=FukumotoMitsuhiro en-aut-sei=Fukumoto en-aut-mei=Mitsuhiro kn-aut-name=福本光宏 kn-aut-sei=福本 kn-aut-mei=光宏 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=Interferon kn-keyword=Interferon en-keyword=Ge-132 kn-keyword=Ge-132 en-keyword=Ok-143 kn-keyword=Ok-143 en-keyword=Neutrophil Chemiluminescence kn-keyword=Neutrophil Chemiluminescence END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=927 end-page=943 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Neuropathological study on neuronal swelling degeneration in the substantia nigra of Olivo-Ponto-Cerebellar Atrophy (OPCA) kn-title=Olivo-Ponto-Cerebellar Atrophy (OPCA) の中脳黒質ニューロンの腫脹性病変について en-subtitle= kn-subtitle= en-abstract= kn-abstract=In 6 out of 7 autopsy cases of olivopontocerebellar atrophy, we found characteristic features of neuronal swelling degeneration (abbr. NSD) in the nerve cell of the substantia nigra. NSD was classified into 4 types according to the microscopic features. The cell body of the type A NSD is much larger than the usual nerve cell, contains melanin granules, is round in shape and appears granular. This cell sometimes contains a shrunken nucleus, Marinesco body, Nissl granules and rest of melanin pigment, suggesting its origin in the degenerating melanin containing nerve cell. In type B NSD the periphery of the swollen cell body appears to be frosted glass with a Nissl Substance. A part of the type B NSD was suggested to have its origin in the nerve cell which has no melanin pigment. Type C NSD is round or irregular in shape and appears to be vacuolar, suggesting its origin in the dendritic process. Type D NSD is sharply bounded from the surrounding tissue and amorphous structures. Judging from its staining characteristics, its origin was suggested to be in the axon. The significance and pathogenesis of the NSD are discussed with special reference to its relation to glutamic acid. en-copyright= kn-copyright= en-aut-name=NambaMasuyuki en-aut-sei=Namba en-aut-mei=Masuyuki kn-aut-name=難波益之 kn-aut-sei=難波 kn-aut-mei=益之 aut-affil-num=1 ORCID= en-aut-name=TanakaTakaho en-aut-sei=Tanaka en-aut-mei=Takaho kn-aut-name=田中隆穂 kn-aut-sei=田中 kn-aut-mei=隆穂 aut-affil-num=2 ORCID= en-aut-name=IshinoHirosi en-aut-sei=Ishino en-aut-mei=Hirosi kn-aut-name=石野博志 kn-aut-sei=石野 kn-aut-mei=博志 aut-affil-num=3 ORCID= en-aut-name=SenoHaruo en-aut-sei=Seno en-aut-mei=Haruo kn-aut-name=妹尾晴夫 kn-aut-sei=妹尾 kn-aut-mei=晴夫 aut-affil-num=4 ORCID= en-aut-name=IshizuHideki en-aut-sei=Ishizu en-aut-mei=Hideki kn-aut-name=石津秀樹 kn-aut-sei=石津 kn-aut-mei=秀樹 aut-affil-num=5 ORCID= en-aut-name=KurodaSigetosi en-aut-sei=Kuroda en-aut-mei=Sigetosi kn-aut-name=黒田重利 kn-aut-sei=黒田 kn-aut-mei=重利 aut-affil-num=6 ORCID= en-aut-name=KuyamaKeisuke en-aut-sei=Kuyama en-aut-mei=Keisuke kn-aut-name=久山圭介 kn-aut-sei=久山 kn-aut-mei=圭介 aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=慈圭精神医学研究所 affil-num=2 en-affil= kn-affil=西宇部病院 affil-num=3 en-affil= kn-affil=島根医科大学神経精神医学教室 affil-num=4 en-affil= kn-affil=島根医科大学神経精神医学教室 affil-num=5 en-affil= kn-affil=岡山大学医学部神経精神医学教室 affil-num=6 en-affil= kn-affil=岡山大学医学部神経精神医学教室 affil-num=7 en-affil= kn-affil=岡山大学医学部神経精神医学教室 en-keyword=OPCA kn-keyword=OPCA en-keyword=Substantia nigra kn-keyword=Substantia nigra en-keyword=neuronal swelling degeneration kn-keyword=neuronal swelling degeneration en-keyword=glutamate kn-keyword=glutamate END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=11-12 article-no= start-page=1173 end-page=1187 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=199212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Long-lasting effects of ceruletide on L-Dopa-induced dyskinesias in monkey kn-title=サルの L-Dopa-induced dyskinesia に対する Ceruletide の長期効果 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The long-lasting effects of ceruletide(CLT), a cholecystokinin-8(CCK-8) analogue, on involuntary movements were investigated. Nine monkeys were used. One group(6 monkeys) received unilateral lesions to the ventromedial tegmentum(VMT) of the midbrain. The second group(3 monkeys) served as controls. Hypokinesia was produced after lesioning of the VMT. Administration of a large amount of L-Dopa or direct intracaudate injection of dopamine(DA) relieved the symptoms initially but then induced dyskinesias later. Two monkeys with reproducible dyskinesias were chosen for further study. Systemically administered CLT combined with L-Dopa improved the hypokinesia without inducing dyskinesia. These effects of a single dose of 50 μg/kg CLT continued up to 9 days. Direct combined administration of CLT and DA into the dorsomedial part of the head of the caudate nucleus ipsilateral to the VMT lesion improved the hypokinesia without inducing dyskinesia. The effect of a single direct injection of 20 ng/kg CLT persisted for 3 days. The long-lasting effects of systemically and directly administered CLT were confirmed. These findings suggest that CLT modulates the DA system indirectly through the central CCK system, especially in the dorsomedial part of the head of the caudate nucleus. en-copyright= kn-copyright= en-aut-name=MizobuchiMasayuki en-aut-sei=Mizobuchi en-aut-mei=Masayuki kn-aut-name=溝渕雅之 kn-aut-sei=溝渕 kn-aut-mei=雅之 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部脳神経外科学教室 en-keyword=Ceruletide kn-keyword=Ceruletide en-keyword=L-Dopa-induced dyskinesia kn-keyword=L-Dopa-induced dyskinesia en-keyword=Cholecystokinin kn-keyword=Cholecystokinin en-keyword=Peptide regulation kn-keyword=Peptide regulation END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=11-12 article-no= start-page=1069 end-page=1078 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=199212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on platelet function in bronchial asthma Part 1.

The results were as follows : 1) Plasma serotonin levels were higher during the attack stage than non-attack stage in asthmatics. 2) Morphological changes and the aggregation of platelets were observed by scanning electron microscopy after stimulation with platelet activating factor(PAF), CaI, anti-IgE and anti-IgG. 3)The serotonin-releasability of platelets stimulated by CaI was significantly decreased in severe asthmatics, compared with mild asthmatics and normal subjects(p<0.05). However, there were no significant differences between steroid dependent and non-steroid dependent intractable asthmatics in severe asthma. 4) The releasability of serotonin was decreased in most cases during asthmatic attack and was suppressed by aminophyllin. 5) The serotonin-releasability of platelets stimulated by anti-IgG of Candida antigen was remarkably enhanced aftre incubation with serum, although releasability was not increased with heart-treated serum. These results suggest that platelets play an important role in bronchoconstriction induced by various immunological reactions involved with complement activation in the pathogenesis of bronchial asthma. en-copyright= kn-copyright= en-aut-name=SunamiKoji en-aut-sei=Sunami en-aut-mei=Koji kn-aut-name=角南宏二 kn-aut-sei=角南 kn-aut-mei=宏二 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=platelet kn-keyword=platelet en-keyword=serotonin kn-keyword=serotonin en-keyword=bronchial asthma kn-keyword=bronchial asthma END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=841 end-page=857 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Experimental study on the hepatic effects of sevoflurane anesthesia kn-title=セボフルレン麻酔の肝に及ぼす影響に関する実験的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The hepatic effects of sevoflurane administered under different inspiratory oxygen concentrations were examined.

The rats administered sevoflurane under 21% oxygen were used as the control. The amount of microsomal protein, the content and activity of hepatic microsomal enzymes, and the amount of enzymes released from the liver cells (GPT, OCT) of each group of rats were measured for 7 days after these procedures. The content of cytochrome P-450 and the activity of aminopyrine demethylation and aniline dehydration were decreased significantly to about 58%, 43% and 40% that of the control, respectively. Furthermore the plasma level of GPT and OCT was elevated to 1,107±620 IU/L and 422±270 IU/L respectively soon after sevoflurane anesthesia only in the group of rats administered sevoflurane under a 10% oxygen concentration. In this study, severe damage to the liver of the rats was observed after sevoflurane anesthesia under 10% oxygen following enzyme induction and fasting. en-copyright= kn-copyright= en-aut-name=OkadaNaoki en-aut-sei=Okada en-aut-mei=Naoki kn-aut-name=岡田尚起 kn-aut-sei=岡田 kn-aut-mei=尚起 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=セボフルレン麻酔 kn-keyword=セボフルレン麻酔 en-keyword=吸入酸素濃度 kn-keyword=吸入酸素濃度 en-keyword=チトクローム P-450 kn-keyword=チトクローム P-450 en-keyword=肝障害 kn-keyword=肝障害 END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=1-2 article-no= start-page=97 end-page=106 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Attitude toward mental disorders : A comparative study of a attitude of nurses and attendants between Japan and Brazil kn-title=精神障害の対する態度―日本, ブラジルの看護婦, 看護士の態度の比較研究― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Attitude of nureses and attendants toward mental disorders was studied by using question-naire in Japan and Brazil. By factor analysis, three factors, negative attitude toward mental disorders and misunder-standing, positive attitude toward mental disorders and mental health ideology were extracted. The score of negative attitude toward mental disorders and misunderstanding was high in Brazil. This was suspected to be caused by poor knowledge about mental disorders. The score of positive attitude toward mental disorders was similar in Japan and Brazil. The score of mental health ideology was high in Japan. Mental health ideology is important to improve the attitude toward mental disorders both Japan and Brazil. It is important to spread knowledge about mental disorders in Brazil. In Japan, it is important to increase the interest in mental disorders. en-copyright= kn-copyright= en-aut-name=TakenamiKatsuko en-aut-sei=Takenami en-aut-mei=Katsuko kn-aut-name=武南克子 kn-aut-sei=武南 kn-aut-mei=克子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部神経精神医学教室 en-keyword=精神障害に対する態度 kn-keyword=精神障害に対する態度 en-keyword=因子分析 kn-keyword=因子分析 en-keyword=精神保健的観念 kn-keyword=精神保健的観念 en-keyword=関心度 kn-keyword=関心度 END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=7-8 article-no= start-page=843 end-page=852 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=Analysis of suppressor T cells induced in long-term human allogeneic mixed lymphocyte culture kn-title=長期リンパ球混合培養で誘導される抑制性T細胞の免疫学的解析 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Suppressor T cells (Ts) may play an important role in the regulation of immunological responses. Ts may play a role in the long-term acceptance of an allogeneic organ graft and the beneficial effects of donor-specific blood transfusions on subsequent transplant survival. The population of Ts induced in mixed lymphocyte culture (MLC) was analyzed, and the mechanism underlying the suppressor activity was examined. The Ts generated in 10-day MLC were found to belong to the OKT8(+) subset and inhibited both mixed lymphocyte reaction (MLR) and cell-mediated lympholysis. These Ts inhibited MLR in an antigen-specific manner, but failed to alter the kinetics of the MLR. Furthermore, these Ts inhibited the production of endogenous interleukin-2 and exerted a suppressive effect only when added early in the culture. In condition, the precise target of Ts generated in 10-day MLC might be the earliest responding T helper clone. en-copyright= kn-copyright= en-aut-name=TsuboiKatsutoshi en-aut-sei=Tsuboi en-aut-mei=Katsutoshi kn-aut-name=壺井克敏 kn-aut-sei=壺井 kn-aut-mei=克敏 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一外科学教室 en-keyword=抑制性T細胞 kn-keyword=抑制性T細胞 en-keyword=リンパ球混合培養 kn-keyword=リンパ球混合培養 en-keyword=mixed lymphocyte reaction kn-keyword=mixed lymphocyte reaction en-keyword=cell-mediated lympholysis kn-keyword=cell-mediated lympholysis END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=791 end-page=801 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the regulation of eosinophils in bronchial asthma Part 2.

Such cell infiltration seems to be induced by the eosinophil chemotactic factor (ECF). PAF and IL-5 are potent chemoattractants and activators for eosinophils. To evaluate the reactivity of eosinophils in asthmatics under various conditions, the migratory function of eosinophils to PAF and IL-5 was investigated by the modified Boyden chamber method. Eosinophils of asthmatics were highly purified using a flow cytometric method previously reported. The migratory response of the eosinophils of asthmatics was greater than that of healthy suljects. Eosinophils from atopic asthmatics showed a higher response to PAF than those from non-atopic asthmatics. Eosinophils in the attack stage showed a higher response than those in the non-attack stage. Hypodense eosinophils showed an increased migratory response. The migratory response was correlated to the serum concentration of ECP and blood eosinophil count. These findings suggest that the reactivity of eosinophils is heterogenous and relates to the degree of eosinophilia, and that IL-5 as well as PAF plays an important role in the pathogenesis of bronchial asthma. en-copyright= kn-copyright= en-aut-name=TakahashiHisaho en-aut-sei=Takahashi en-aut-mei=Hisaho kn-aut-name=高橋寿保 kn-aut-sei=高橋 kn-aut-mei=寿保 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=Bronchial asthma kn-keyword=Bronchial asthma en-keyword=Eosinophil migratory response kn-keyword=Eosinophil migratory response en-keyword=Platelet-activating factor kn-keyword=Platelet-activating factor en-keyword=Interleukin-5 kn-keyword=Interleukin-5 en-keyword=Eosinophil heterogeneity kn-keyword=Eosinophil heterogeneity END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=5-6 article-no= start-page=641 end-page=654 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=1994 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The pathogenesis of interstitial pneumonia and the role of cytokines kn-title=間質性肺疾患の病態に関する研究―気管支肺胞洗浄液中サイトカインの検討― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Various cytokines are known to participate in the pathogenesis of interstitial pneumonia follewed by lung fibrosis due to the proliferation of fibroblasts and production of collagen fibers. Patients with interstitial pneumonia including idiopathic interstitial pneumonia (IIP) and interstitial pneumonia with collagen vascular disease (IP with CVD) were examined by bronchoalveolar lavage (BAL). Cytokines such as IL-1α, TGF-α, and TGF-β in BAL fluid were measured by enzyme linked immunosorbent assay (ELISA). The concentrations of TGF-α and TGF-β in BAL fluid of patients with IIP and IP with CVD were higher than those of normal control, while IL-1α, in BAL fluid was detected in few patoents. The level of TGF-β in BAL fluid was higher in patients with greater decreases in pulmonary function and overt fibrosis on chest X-ray film, although TGF-α was higher in patients with milder disorders. The concentrations of TGF-α and TGF-β showed positive correlation with soluble IL-2 receptor as well as procollagen type Ⅲ in BAL fluid. These results indicated that cytokines regulationg lung fibrosis play important roles in the pathogenesis of interstitial pneumonia. en-copyright= kn-copyright= en-aut-name=SugimotoKeisuke en-aut-sei=Sugimoto en-aut-mei=Keisuke kn-aut-name=杉本啓介 kn-aut-sei=杉本 kn-aut-mei=啓介 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=間質性肺疾患 kn-keyword=間質性肺疾患 en-keyword=気管支肺胞洗浄法 (broncho alveolar lavage : BAL) kn-keyword=気管支肺胞洗浄法 (broncho alveolar lavage : BAL) en-keyword=Interleukin 1 (IL-1) kn-keyword=Interleukin 1 (IL-1) en-keyword=transforming growth factor α kn-keyword=transforming growth factor α en-keyword=transforming growth factor β kn-keyword=transforming growth factor β END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=7-8 article-no= start-page=747 end-page=761 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=Chemical and physiological changes of serum and thoracic-duct lymph in the dog with experimental obstructive jaundice and/or disorder of liver circulation kn-title=実験的閉塞性黄疸および肝循環障害における血清と胸管リンパ液組成の変動に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=A long-term study on the chemical and physiological changes of serum and thoracic-duct lymph in the dog with a ligated common bile duct and/or artificial liver circulation was performed. The influencee of ligation of the common bile duct appeared earlier in the thoracic-duct lymph than in the serum. The portal pressure did not increase in the dog with a ligated common bile duct, but the lymph flow of the thoracic duct was 3 times that before ligation, which would prevent the rapid stagnation of bile pigment in the liver. The portal pressure was not elevated after ligation of the hepatic artery. The cholesterol level in the thoracic-duct lymph was about half of that in the serum. In the dog with ligature of the common bile duct, the serum total cholesterol level was elevated with the elevation of serum bilirubin, whereas that in the lymph of the thoracic duct was not elevated with the elevation of the bilirubin level in the lymph. These findings suggested that cholesterol would not easily enter into the lymphatic route. The serum GPT level increased during the first week after ligation of the hepatic artery, and decreased thereafter. However, after ligation of the common bile duct, the GPT level increased for several weeks after the first week of ligation. The pattern of GPT by both ligations seemed to be cross-crossed. The marked change in the total bilirubin level in the lymph of the thoracic duct suggested its close relation with the lymphatic system. It was proved possible to secure a tube into the thoracic duct for over three weeks by the use of a U-type connector and jacket-type plaster cast. en-copyright= kn-copyright= en-aut-name=UedaYuzo en-aut-sei=Ueda en-aut-mei=Yuzo kn-aut-name=上田祐造 kn-aut-sei=上田 kn-aut-mei=祐造 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一外科学教室 en-keyword=実験的肝障害 kn-keyword=実験的肝障害 en-keyword=閉塞性黄疸 kn-keyword=閉塞性黄疸 en-keyword=肝循環障害 kn-keyword=肝循環障害 en-keyword=胸管リンパ液 kn-keyword=胸管リンパ液 en-keyword=胸管カヌレーション kn-keyword=胸管カヌレーション END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=779 end-page=789 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the regulation of eosinophils in bronchial asthma Part 1.

The eosinophil chemotactic factor (ECF) derived from mononuclear cells has been reported to have some effect on the cell infiltration, and interleukin-5 (IL-5), a lymphokine derived from T lymphocytes, to be a factor related to growth, chemotaxis and activation for eosinophils. Lymphocytes accumulated in the bronchoalveolar lavage fluids of non-atopic and severe asthmatics have been shown to be highly responsive to Candida antigen, and high ECF production was observed in non-atopic and severe asthmatics by measurement of ECF activity in the supernatant of peripheral blood mononuclear cells cultured with Candida antigen. In this report, the molecular weight by gel filtration and inhibition test using anti-murine IL-5 antibody were studied to characterize the lymphocyte-derived ECF. Gel filtration analysis of the ECF indicated a molecular weight of 20,000 to 65,000 Da with a peak of activity around 40,000 to 50,000 Da. The ECF activity was reduced by incubation with anti-murine IL-5 antibody, which suggests that the supernatant contains IL-5. ECF from mononuclear cells, containing IL-5, may play an important role in the pathogenesis of eosinophil infiltration in non-atopic and severe asthmatics. en-copyright= kn-copyright= en-aut-name=TakahashiHisaho en-aut-sei=Takahashi en-aut-mei=Hisaho kn-aut-name=高橋寿保 kn-aut-sei=高橋 kn-aut-mei=寿保 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=Bronchial asthma kn-keyword=Bronchial asthma en-keyword=Candida antigen Eosinophil chemotactic factor kn-keyword=Candida antigen Eosinophil chemotactic factor en-keyword=Interleukin-5 kn-keyword=Interleukin-5 END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=769 end-page=778 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Striatal extracellular levels of dopamine and its metabolites during kainate-induced limbic seizures in freely-moving rats measured by brain microdialysis kn-title=カイニン酸誘発けいれんにおける細胞外ドパミン量の経時的変化―脳内微小透析法を用いた実験的研究― en-subtitle= kn-subtitle= en-abstract= kn-abstract=To investigate the role of brain dopaminergic systems in epilepsy, striatal extracellular levels of dopamins (DA) and its metabolites (3,4-dihydroxyphenylacetic acid : DOPAC and homovanillic acid : HVA) were measured during kainate-induced limbic seizures in freely-moving rats, using brain microdialysis. DA and its metabolites were measured by high performance liquid chromatography. Systemic injection of kainate (10mg/㎏, i. p.), which caused stable limbic seizures, significantly decreased the levels of DA and its metabolites. Intrahippocampal injection of kainae (2.5nmol), which also caused limbic seizures, significantly decreased only the DA levels, while DOPAC and HVA levels were unchanged. Similar to the results of the systemic injectjon, intrastriatal perfusion of kainate (10(-2) or 10(-6) M) significantly decreased the levels of DA, DOPAC and HVA in a dose-dependent manner. These findings indicate that, during kainate-induced limbic seizures, DA release was significantly reduced in the striatum. In conclusion, the hypofunction of striatal dopaminergic systems is related to the initiation and progress in epileptic seizures. en-copyright= kn-copyright= en-aut-name=OhnishiMasaru en-aut-sei=Ohnishi en-aut-mei=Masaru kn-aut-name=大西勝 kn-aut-sei=大西 kn-aut-mei=勝 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部神経精神医学教室 en-keyword=kainate kn-keyword=kainate en-keyword=brain microdialysis kn-keyword=brain microdialysis en-keyword=dopamine kn-keyword=dopamine en-keyword=striatum kn-keyword=striatum en-keyword=epilepsy kn-keyword=epilepsy END start-ver=1.4 cd-journal=joma no-vol=105 cd-vols= no-issue=5-6 article-no= start-page=589 end-page=600 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=1993 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies of human bone marrow stromal cells in the aged Part 1.

The composition of BMSC was analyzed by immunofluorescence. The percentage of monocyte/macrophages, adipocytes and T-cells were significantly increased in the aged. BMSC from the aged proliferated more rapidly than those from the young during the first week of culture in the growing dynamics study. Cytokine concentration in the conditioned medium was also measured in terms of BMSC function by radioimmunoasssay or enzyme-linked immunosorbent assay. The concentration of macrophage colony stimulating factor (M-CSF) on day 21 increased in the culture from the young, while interleukin-6(IL-6) concentration was higher on day 7 in the culture from the aged. These findings show no evidnece of BMSC defects in the aged.

Therefore, some clinical or adverse effects of neuroleptics may be due to their action on the sigma sites. This study showed that intrarubral microinjection of 1,3-di-o-tolylguanidine (DTG) or (+) -3- (3-hydroxyphenyl) -N-1-propyl) piperidine, sigma ligands, and several neuroleptics such as haloperidol caused dystonic reactions in rats resembling tha acute dystonic reaction in humans. The intensity and duration of the dystonia induced by these drugs showed a correlation with their affinities for the sigma sites. These findings raise the possibility that the acute dystonic reaction, one of the motor side effects of neuroleptics, might be mediated via the sigma sites. On the other hand, BMY 14802, an atypical neuroleptic, never caused dystonia after intrarubral microinjection. Furthermore, BMY 14802 still inhibited the dystonia induced by intrarubral microinjection of DTG. This reduction in DTG-induced dystonia by BMY 14802 may result its direct inhibitory effects against DTG at the sites, because BMY 14802 possesses potent sigma affinty. These findings imply that sigma ligands may be divided into two categories, dystonia-reinforcing and -reducing groups. Application of this theory should lead to the elucidation of the mechanism of neuroleptics-induced dystonia and other motor side effects. en-copyright= kn-copyright= en-aut-name=OkumuraKazuya en-aut-sei=Okumura en-aut-mei=Kazuya kn-aut-name=奥村一哉 kn-aut-sei=奥村 kn-aut-mei=一哉 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部神経精神医学教室 en-keyword=sigma sites kn-keyword=sigma sites en-keyword=dystonia kn-keyword=dystonia en-keyword=1, 3 -di-o-tolylguanidine (DTG) kn-keyword=1, 3 -di-o-tolylguanidine (DTG) en-keyword=BMY 14802 kn-keyword=BMY 14802 en-keyword=neuroleptics kn-keyword=neuroleptics END start-ver=1.4 cd-journal=joma no-vol=105 cd-vols= no-issue=5-6 article-no= start-page=437 end-page=445 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=1993 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Clinical studies on atypical leukemia Part 2.

Among 8 patients treated with a low-dose (4)N-Behenoyl-β-D-Arabinofuranosyl cytosine (LD-BHAC) regimen, in which 50mg BHAC was administered daily intravenously by one-hour drip infusion for 14 days, 4 patients obtained complete remission (CR) and 2 patients obtained partial remission (PR). The response rate (CR+PR) was 75%. The responders were all over 65 years old. Although hematological toxicities and adverse effects on the digestive system such as anorexia and nausea were observed, they were all controllable by conventional treatments. The serum concentrations of ara-C were measured in 4 patients. Serum ara-C reached the peak concentration, 3.62-18.9 ng/ml (mean : 11.74 ng/ml), at the cessation of BHAC infusion, and a serum ara-C level of 2.75-4.89 ng/ml (mean : 3.54 ng/ml) was still present 6 hours after the cessation of infusion. Among 44 patients hospitalized before 1984, 27 patients were treated with blood transfusion and /or single antileukemic agent and 17 patients received combination chemotherapeutic regimens. Only 8 of 44 patients attained CR. The responders were all below 65 years old, and except for one patient, received combination chemotherapy. These results suggest that LD-BHAC therapy is useful in the clinical management of hypoplastic leukemia as a remission induction chemotherapy. en-copyright= kn-copyright= en-aut-name=NakadaHiroshi en-aut-sei=Nakada en-aut-mei=Hiroshi kn-aut-name=仲田浩之 kn-aut-sei=仲田 kn-aut-mei=浩之 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=atypical leukemia kn-keyword=atypical leukemia en-keyword=therapy of hypoplastic leukemia kn-keyword=therapy of hypoplastic leukemia en-keyword=low dose behenoyl-ara-C therapy kn-keyword=low dose behenoyl-ara-C therapy en-keyword=behenoyl-ara-C kn-keyword=behenoyl-ara-C END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=3-4 article-no= start-page=325 end-page=334 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=1994 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Enhancement of anti-tumor activity of 1-β-D-arabinofuranosyl-cytosine kn-title=1-β-D-arabinofuranosyl-cytosineの抗腫瘍効果増強に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=1-β-D-arabinofuranosyl-cytosine (ara-C) is one of the most effective agents in the chemo-therapy of acute non-lymphocytic leukemia (ANLL). Herein, the effects of uracil(U), deoxyuridine (UdR) and uridine (UR) on the anti-tumor activity of ara-C and on ara-C accumulation in the cells were studied. Growth-inhibition activities of ara-C alone and in combination with U, UdR and UR were determined by the trypan blue method. Cell-killing activities against MOLT-4, HL60, human leukemic progenitors (L-CFU) and human colony forming units (G-CSF) were determined by a colonogenic assay. The growth-inhibition activity of ara-C against MOLT-4 and HL60 was not enhanced by U or UdR. On the other hand, 10(-3)mol UR enhanced the growth-inhibition activity of ara-C against both MOLT-4 and HL60. The 50% inhibition dose (ID50) of ara-C was 6.0×10(-7)mol for MOLT-4 and 4.0×10(-7)mol for MOLT-4 and HL60. On the other hand, in the culture medium containing 10(-3)mol UR ID50 was 3.0×10(-8)mol for MOLT-4 and HL60. Cell-killing acticvity of ara-C was enhanced by 10(-3)mol UR. The 50% lethal dose (LD50) of ara-C for MOLT-4 and HL60 was decreased from 9.0×10(-7)mol to 5.0×10(-8)mol and from 5.0×10(-7)mol to 5.0×10(-8)mol after a 72-hour exposure to 10(-3)mol of UR, respectively. Cell-killing activity of ara-C against L-CFU was enhanced by 10(-3)mol UR in 4 of the 9 ANLL patients. On the other hand, the cell-killing activity of ara-C against G-CSF was enhanced in 2 of the 9 healthy individuals. 10(-8)mol ara-C, UR enhanced the cell-killing activity against L-CFU in 2 of the 9 ANLL patients, but not for G-CSF. Accumlation of (3)H-sra-C in MOLT-4 cells at 12, 24 and 48 hours was significantly increased in culture medium containing 10(-8)mol of (3)H-ara-C and 10(-3)mol of UR. Accumulation of 3H-ara-C in HL60 cells at 24 and 48 hours was also significantly increased. It is noteworthy that the cell-killing activity of ara-C against not only human lymphoid and myeloid leukemic cell lines but also L-CFU was enhanced by the combination with a nucleoside (UR), but not with anti-lrukemic agents. These findings provide some information on the enhancement of the anti-tumor activity and mechanims of resistance of ara-C. en-copyright= kn-copyright= en-aut-name=HayashiNaoki en-aut-sei=Hayashi en-aut-mei=Naoki kn-aut-name=林直樹 kn-aut-sei=林 kn-aut-mei=直樹 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=1-β-D-arabinofuranosyl-cytosine kn-keyword=1-β-D-arabinofuranosyl-cytosine en-keyword=cytosine arabinoside kn-keyword=cytosine arabinoside en-keyword=uridine kn-keyword=uridine en-keyword=enhancement of antitumor effect kn-keyword=enhancement of antitumor effect en-keyword=in vitro chemotherapy kn-keyword=in vitro chemotherapy END start-ver=1.4 cd-journal=joma no-vol=105 cd-vols= no-issue=1-2 article-no= start-page=217 end-page=226 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=19930227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The effects of MCI-186 for ischemic-reperfusion injury during cardiopulumonary bypass kn-title=新しい free radical scavenger MCI-186 の心筋保護効果に関する実験的検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To determine the efficacy of MCI-186, a novel free radical scavenger, in ischemia-reperfusion injury during cardiopulumonary bypass (CPB), the following experimental model was applied. Twenty-one mongrel dogs were subjected to 120 minutes of hypothermic global ischemia by aortic cross clamping with intermittent administration of a cardioplegic solution followed by 60 minutes reperfusion. They were assingend to three groups : group A(n=7), no drug was administerd before reperfusion ; group B(n=7), 1ml/kg of physiological saline was administered by bolus injection through the aortic root just before reprefusion ; group C(n=7), MCI-186 (3mg/ml/kg) dissolved in physiological saline was administered in the same manner as group B. Cardiac function (left ventricular systolic pressure, cardiac output, left ventricular maximum dP/dt) after 60 minutes reperfusion expressed as as percent recovery of pre-ischemic state was superior in group C than in groups A and B. Release of lipidperoxide assayed by the TBA method as the difference between coronary artery and sinus were suppressed in the early phase of reperfusion in group C. Myocardial water content after 60 minutes reperfusion was also less in group C than in group A and B.

In the L-Ⅰand L-Ⅱgroups, dogs were administered Li (10mg/kg) immediately after the end of ischemia (post-treatment). Only in the L-Ⅱ group, dogs were administered Li (100mg/kg) orally one day before the ischemic insult (pre-treatment). In each group, nuerologic outcome was evaluated for seven days after ischemia, and morphological changes in hippocampal CA1 pyramidal cells, small to medium-sized striatal neurons and cerebellar Purkinje cells were evaluated at day seven. In the L-Ⅱ group, neutrologic outcome was significantly better than that in the control group, and morphological improvement was recognized. Pre-treatment with Li might improve both neurologic and morphologic outcomes due to powerful inhibition of the stimulated phosphoinositide turnover during ishchemia. These fingings suggest that the stimulated phosphoinositide turnover during and immediately after ischemia might play an important role in brain injury induced by 18 minutes of complete global brain ischemia. en-copyright= kn-copyright= en-aut-name=YaidaYutaka en-aut-sei=Yaida en-aut-mei=Yutaka kn-aut-name=八井田豊 kn-aut-sei=八井田 kn-aut-mei=豊 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=完全全脳虚血 kn-keyword=完全全脳虚血 en-keyword=イノシトールリン脂質作動系 kn-keyword=イノシトールリン脂質作動系 en-keyword=炭酸リチウム kn-keyword=炭酸リチウム END start-ver=1.4 cd-journal=joma no-vol=105 cd-vols= no-issue=7-8 article-no= start-page=771 end-page=778 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=199308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Flowcytometric studies of effects of heat on DNA synthesis in different thermosensitivities mammalian cell lines kn-title=温熱感受性の異なる培養細胞の DNA 合成に対する温熱効果―フローサイトメトリーによる研究― en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effect of heat on DNA synthesis in HeLa S3 cells and L-5 cells was studied using flowcytometry. When D(0) values obtained from survival curves of Ehrlich ascites tumor cells, L-5 cells, HeLa S3 cells and NIH3T3 cells after heating to 43, 44, or 45℃, were compared, HeLa S3 cells were resistant and L-5 cells were sensitive to heating. During heating at 43℃, DNA synthesis (BUdR uptake) of HeLa S3 cells was resistant compared to that of L-5 cells. When the period of DNA synthesis was divided into 3 fractions (early S, mid S and late S), late S phase was the most sensitive fraction to heating at 43℃ for 60 minutes. From these results, relationship between DNA synthesis and thermocytotoxic effects are discussed. en-copyright= kn-copyright= en-aut-name=TanakaSeiryou en-aut-sei=Tanaka en-aut-mei=Seiryou kn-aut-name=田中聖了 kn-aut-sei=田中 kn-aut-mei=聖了 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部放射線医学教室 en-keyword=Flowcytometry kn-keyword=Flowcytometry en-keyword=DNA synthesis kn-keyword=DNA synthesis en-keyword=Heating kn-keyword=Heating en-keyword=BUdR kn-keyword=BUdR END start-ver=1.4 cd-journal=joma no-vol=55 cd-vols= no-issue=9 article-no= start-page=707 end-page=713 dt-received= dt-revised= dt-accepted= dt-pub-year=2006 dt-pub=20061117 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Development of Computer-Controlled Flow Injection Instruments and Its Application to Determination of Nitrate, Nitrite, and Ammonium Ions in Environmental Samples kn-title=コンピュータ制御されたフローインジェクション分析装置の開発と環境水中の硝酸イオン,亜硝酸イオン,アンモニウムイオン定量への応用 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Flow injection analysis (FIA) systems with low power consumption and personal-computer control were developed by using solenoid pumps and an LED detector.

Linear calibration graphs were obtained with the combination of pump(s) and photometric detector in the concentration range of nitrite ion at 0.5∼3.0 × 10−6 M. Nitrate and nitrite ions were also determined simultaneously by the system by using a Cd/Cu reduction column and a by-pass flow. Determination of ammonia in river-water samples was also realized by the system with a modified indophenol reaction. en-copyright= kn-copyright= en-aut-name=JoichiYasutaka en-aut-sei=Joichi en-aut-mei=Yasutaka kn-aut-name=城市康隆 kn-aut-sei=城市 kn-aut-mei=康隆 aut-affil-num=1 ORCID= en-aut-name=NarongLenghor en-aut-sei=Narong en-aut-mei=Lenghor kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakayanagiToshio en-aut-sei=Takayanagi en-aut-mei=Toshio kn-aut-name=高柳俊夫 kn-aut-sei=高柳 kn-aut-mei=俊夫 aut-affil-num=3 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=4 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=5 ORCID= en-aut-name=UraNobuo en-aut-sei=Ura en-aut-mei=Nobuo kn-aut-name=浦信夫 kn-aut-sei=浦 kn-aut-mei=信夫 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部化学科 affil-num=2 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 affil-num=3 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 affil-num=4 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 affil-num=5 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 affil-num=6 en-affil= kn-affil=株式会社相馬光学 en-keyword=Flow injection analysis kn-keyword=Flow injection analysis en-keyword=LabVIEW control kn-keyword=LabVIEW control en-keyword=solenoid pumps kn-keyword=solenoid pumps en-keyword=nitrate ion kn-keyword=nitrate ion en-keyword=nitrite ion kn-keyword=nitrite ion en-keyword=ammonia kn-keyword=ammonia END start-ver=1.4 cd-journal=joma no-vol=55 cd-vols= no-issue=9 article-no= start-page=715 end-page=720 dt-received= dt-revised= dt-accepted= dt-pub-year=2006 dt-pub=20061117 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Highly Efficient and Automatic Collection/Concentration with Chelating Resin for Inductively Coupled Plasma Atomic Emission Spectroscopy kn-title=誘導結合プラズマ発光分析のためのキレート樹脂を用いる高効率自動前処理濃縮 en-subtitle= kn-subtitle= en-abstract= kn-abstract=An automatically controlled collection/concentration system for ICP-AES was developed. Elements were collected with small chelating disks and chelating resin with the iminodiacetate moiety packed in a line filter. This column was installed in a 6-way valve on the pretreatment system, which could be connected on line to ICP-AES. The flow rate was 1 ml min−1 and conditioning of the chelating disk was carried out by flowing 0.5 M ammonium acetate (pH 5.5) for 2 min, sampling for 5 min and washing for 1 min. Elution was done by passing through 2 M HNO3 at 1.3 ml min−1 for 1 min. Bi, Cd, Co, Cr, Cu, Mn, Ni, Pb and V could be determined with 5.0 ml of the sample solution. The enrichment factors were 3∼15 times and the collection efficiencies were better than 80%. The detection limits (LOD) were from 0.003 for Mn to 0.311 for Bi, which were several 10 to 100-times lower than that of normal LOD of ICP-AES. This method was successfully applied to the determination of these metals in tap and river-water samples. en-copyright= kn-copyright= en-aut-name=YamamotoTakako en-aut-sei=Yamamoto en-aut-mei=Takako kn-aut-name=山本貴子 kn-aut-sei=山本 kn-aut-mei=貴子 aut-affil-num=1 ORCID= en-aut-name=AkhmadSabarudin en-aut-sei=Akhmad en-aut-mei=Sabarudin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NoguchiOsamu en-aut-sei=Noguchi en-aut-mei=Osamu kn-aut-name=野口修 kn-aut-sei=野口 kn-aut-mei=修 aut-affil-num=3 ORCID= en-aut-name=TakayanagiToshio en-aut-sei=Takayanagi en-aut-mei=Toshio kn-aut-name=高柳俊夫 kn-aut-sei=高柳 kn-aut-mei=俊夫 aut-affil-num=4 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=5 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部化学科 affil-num=2 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 affil-num=3 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 affil-num=4 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 affil-num=5 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 affil-num=6 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 en-keyword=automated collection/concentration kn-keyword=automated collection/concentration en-keyword=chelating disk and chelating resin kn-keyword=chelating disk and chelating resin en-keyword=ICP-AES kn-keyword=ICP-AES en-keyword=heavy metals kn-keyword=heavy metals END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=9-10 article-no= start-page=1073 end-page=1084 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=199410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Effect of zinc on halothane-induced liver injury in rats kn-title=ラットにおけるハロタン肝障害に及ぼす亜鉛の影響 en-subtitle= kn-subtitle= en-abstract= kn-abstract=In a rat model, halothane causes liver injury by reductive interaction with microsomal cytochrome P-450 (P-450) and /or by a hepatotoxic effect mediated by halothane-derived free radicals. Rats that were pretreated with phenobarbital (0.1% in drinking water for 6 days) and fasted for the last day, then exposed to halothane (1.0%) under reduced oxygen tension (14%) for 2 horus developed hepatic centrilobular necrosis with marked elevation in serum GPT (GPT) 24 h after exposure. Pretreatment with a 5 mg/kg dose of zinc (Zn) 24 h prior to the exposure had no effect on GPT and liver necrosis. However, 10mg/kg and 20 mg/kg of Zn significantly decreased GPT and liver necrosis. Zn-pretreatment (5-20 mg/kg) significantly depleted hepatic microsomal P-450 before exposure in a dose dependent manner. Hepatic metallothionein (MT)-1 and MT-2 induced by Zn in a dose dependent manner and the levels did not significanlty differ prior to and after exposure to halothane under hypoxic conditions in all Zn-pretreated groups of rats. These results indicated that Zn-pretreatment has some protective effect against halothane-induced liver injury and suggested that this protective effect of Zn involves the depletion of P-450 which results in reduced interacton between P-450 and halothane in the microsomes and is not the result of MTs acting as free radical scavengers. en-copyright= kn-copyright= en-aut-name=HidakaHidekuni en-aut-sei=Hidaka en-aut-mei=Hidekuni kn-aut-name=日高秀邦 kn-aut-sei=日高 kn-aut-mei=秀邦 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=ハロタン kn-keyword=ハロタン en-keyword=肝障害 kn-keyword=肝障害 en-keyword=亜鉛 kn-keyword=亜鉛 en-keyword=チトクローム P-450 kn-keyword=チトクローム P-450 en-keyword=メタロチオネイン kn-keyword=メタロチオネイン END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=9-10 article-no= start-page=1035 end-page=1051 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=199410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Experimental study of L-Dopa induced abnormal involuntary movements in monkey kn-title=サルの L-Dopa 誘発不随意運動に関する実験的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hypokinesia in the unilateral limbs was induced in 8 monkeys (Macaca fuscata fuscata) by a lesion in the contralateral mesencepahlic ventromedial tegmentum (VMT). Daily oral administration of L-Dopa/carbidopa (40mg/kg, 4mg/kg) relieved the hypokinesia and thereafter induced continuous abnormal (choreo-athetoid) involuntary movements (AMI) in upper and lower limbs contralateral to the lesion. These movements were always uniform and continued for a few hours. The author performed a series of pharmacological studies using these VMT-lesioned monkeys. 1) Direct injection of dopamine (500-1000μg/10μl) and apomorphine (500-1500μg/10μl)into the dorsomedial part of the head of the caudate nucleus ipsilateral to the VMT lesion induced the same AIM as those induced by oral administration of L-Dopa/carbidopa. However, intraputaminal injection of these agents induced AIM in bucco-lingual region only. 2) After oral administration of L-Dopa/cabidopa, direct injection of methionine-enkephalin (300μg/10μl), GABA (500-1000μl/10μl) and serotonin (100-200μg/10μl) into the dorsomedial part of the head of the caudate nucleus (HCN) slightly decreased the AIM. However, substance p(200-400μg/10μl) or atropine (100-200μg/10μl) had no effect on the AIM. Neither the direct injection of GABA (500-1000μg/10μl) nor substance P (200-400μg/10μl) into the internal segment of the globus pallidus had any effect of the AIM. 3) The dopaminergic receptor (DA-2) binding study was performed on caudate tissues which were removed 5 weeks after creating the lesion in the unilateral VMT. DA-2 receptor binding of the dorsomedial part of the caudate nucleus, ipsilateral to the lesion, had a higher affinity than that of the ipsilateral ventrolateral part or the contralateral caudate tissue. These results suggest that denervation supersensitivity of the post-synaptic DA-2 receptors in the dorsomedial part of the caudate nucleus is a basic condition for the development of L-Dopa induced AIM, and the postdopaninergic neuronal systems in the caudate nucleus are slightly suppressed by the intra-caudate neurons, of which transmitter substances are methionine-enkephalin, GABA and serotonin. en-copyright= kn-copyright= en-aut-name=SakuraiMasaru en-aut-sei=Sakurai en-aut-mei=Masaru kn-aut-name=桜井勝 kn-aut-sei=桜井 kn-aut-mei=勝 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部脳神経外科学教室 en-keyword=L-Dopa kn-keyword=L-Dopa en-keyword=involuntary movement kn-keyword=involuntary movement en-keyword=striatum kn-keyword=striatum en-keyword=centrally acting agents kn-keyword=centrally acting agents en-keyword=dopaminergic receptor kn-keyword=dopaminergic receptor END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=9-10 article-no= start-page=963 end-page=971 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=199410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The clinical features and pathogenesis of premenstrual asthma : Effect of progesterone and β-estradiol on lymphocyte activation kn-title=月経喘息の臨床的意義とその発症機序に関する研究―リンパ球機能に及ぼす影響を中心に― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although premenstrual worsening of asthma is recognized, little is known about the pathophysiology. Monthly variation in endogenous progesterone and β-estradiol may be associated with the etiology of premenstrual asthma (PMA). T lymphocytes play an importanat role in the pathogenesis of asthma. Therefore, to clarify the pathogenesis of PMA, the clinical features and effects of progesterone and β-estradiol on lymphocyte activation were studied. 1) Thirty one asthmatic females of reproductive age were surveyed. Fourteen asthmatics (45%) claimed their asthma symptoms worsened just prior to or during the menses. Comparing asthmatics with and without PMA, the former group showed significantly more severe steroid dependent asthma. 2) Progesterone and β-estradiol suppressed lymphocyte blastogenesis stimulated by phytohemagglutinin (PHA), mite and Candida antigen. There was no significant difference in the suppression rate between asthmatics and normal subjects, or between male and female. These findings suggest that T lymphocytes may be activated by causal allergens when progesterone and β-estradiol levels decrease during the premenstrual period. Activated T lymphocytes may contribute to the pathogenesis of PMA. en-copyright= kn-copyright= en-aut-name=GotoMotoko en-aut-sei=Goto en-aut-mei=Motoko kn-aut-name=後藤基子 kn-aut-sei=後藤 kn-aut-mei=基子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=Premenstrual asthma kn-keyword=Premenstrual asthma en-keyword=T-cell kn-keyword=T-cell en-keyword=Progesterone kn-keyword=Progesterone en-keyword=β-estradiol kn-keyword=β-estradiol END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=9-10 article-no= start-page=947 end-page=962 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=199410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Low dose melphalan for myelodysplastic syndrome kn-title=骨髄異形成症候群における melphalan 少量療法の検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Myelodysplastic syndrome (MDS) is a disorder of multipotential hematopoietic stem cells. There is no effective therapy for MDS, especially for MDS associated with an excess of blasts, such as refractory anemia with excess blasts (RAEB) or RAEB in transformation (RAEBt). We previously reported the effect of K-18 (a human IgG-melphalan conjugate) in 15 patients with RAEB or RAEBt. The overall response rate was not high, but no side effects were noted. Although the mode of action of K-18 is not certain, it was suggested that the effect was associated with the activity of melpahlan itself. Therefore, low-dose melphalan therapy was initiated in eldery patients with RAEB or RAEBt. Six patients with RAEB and 12 patients with RAEBt received 2mg oral administration daily. Median age of the patients was 64. Six patients achieved complete remission (CR), one patient showed a partial response and four patients had a minor response. Total dosage of melpahlan for patients who achieved CR was 143±18 mg. Median duration of CR was 14.5 months. Serious toxicity was not encountered in any case and neither marrow suppression nor pancytopenia were observed in cases that achieved CR during the administration of melphalan. Changes in cell surface markers (CD34, CD33, CD13) were examined during the time course of CR in two cases. CD34 + cells decreased rapidly during the first two weeks and CD34-CD33+cells increased after four weeks of melpahlan administration. Studying the clinical course of CR with cell surface marker analysis provided evidence that melphalan therapy induced differentiation of transformed hemopoietic precursors. We conclude that daily chronic administration of melpahlan is a useful therapy for elderly patients with RAEB or RAEBt. en-copyright= kn-copyright= en-aut-name=TakabaSeiji en-aut-sei=Takaba en-aut-mei=Seiji kn-aut-name=高場成治 kn-aut-sei=高場 kn-aut-mei=成治 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=RAEB kn-keyword=RAEB en-keyword=RAEBt kn-keyword=RAEBt en-keyword=low dose melpahlan therapy kn-keyword=low dose melpahlan therapy en-keyword=CD34 kn-keyword=CD34 en-keyword=CD33 kn-keyword=CD33 END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=1-2 article-no= start-page=93 end-page=102 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=199402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Hypoplastic leukemia : Chemotherapy for bone marrow dyslasia kn-title=低形成型白血病に関する臨床的研究―血球形態異常と化学療法効果との関連― en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effect of chemotherapy on dysplasia of bone marrow cells was studied in 10 patients with hypoplastic leukemia. Patients were all previously untreated, and ages ranged from 40 to 81 years old (median : 70). Male to female ratio was 1 : 1. Morphologic features studied were pseudo-Pelger neutrophils, absence or decreased Azur granules in the neutrophilis, multinu-cleated erythroblasts, megaloblastoid changes in erythroblasts, micromegakaryocytes, mononuclear megakaryoctes and megekaryocytes with multiple small separated nulei. Although 8 patients with chemotherapeutic effect showed little evidence of dysplasia, 2 patients without chemotherapeutic effect showed severe dysplasia in two or three blood cell lineages. These findings sre thought to indicate that a part of hypoplastic leukemia develops from myelodysplasia with hypoplastic marrow. The establishment of an optimal treatment for hypoplastic leukemia should be sytudied by stratification of bone marrow dysplasia. en-copyright= kn-copyright= en-aut-name=FukudaShunichi en-aut-sei=Fukuda en-aut-mei=Shunichi kn-aut-name=福田俊一 kn-aut-sei=福田 kn-aut-mei=俊一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=hypoplastic leukemia kn-keyword=hypoplastic leukemia en-keyword=dysplasia of blood cells kn-keyword=dysplasia of blood cells en-keyword=chemotherapy kn-keyword=chemotherapy en-keyword=scoring system kn-keyword=scoring system END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=7-8 article-no= start-page=907 end-page=915 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=199408 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Establishment of antigen specific T cell clones from asthmatic patients including evaluation of cytokine production kn-title=気管支喘息における抗原特異的 T cell clone の樹立とサイトカイン産生能に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To clarify the pathogenesis of bronchial asthma, we establishied T cell clones specific for Candida antigen and for mite antigen from the peripheral blood of three asthmatic patients. Flow cytometric analysis was performed on these clones. The surface phenotype of all clones was helper/inducer type. These clones were analyzed for the ability to produce interferon gammma (IFN-γ) and interleukin 4 (IL-4). The T cell clone established from tne patient who showed late asthmatic response (LAR) after bronchial inhalation of Candida, as well as the clones from the patient who showed IAR and LAR after inhalation of housedust mite, produced a higher amount of IFN-γ and lower amount of IL-4. The T cell clone established from the patient who were under corticosteroid therapy and showed IAR after inhalation of Candida produced lower amounts of IFN-γ and IL-4, which seemed to be inhibition of cytokine production from antigen specific T cell clone by corticosteroids. These findings indicate that T cell clones established from the patients who showed LAR produced a large amount of IFN-γ, suggesting that IFN-γ plays an important role in allergic reactions of LAR. en-copyright= kn-copyright= en-aut-name=MiyaharaNobuaki en-aut-sei=Miyahara en-aut-mei=Nobuaki kn-aut-name=宮原信明 kn-aut-sei=宮原 kn-aut-mei=信明 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=antigen specific T cell clone kn-keyword=antigen specific T cell clone en-keyword=IFN-γ kn-keyword=IFN-γ en-keyword=bronchial asthma kn-keyword=bronchial asthma en-keyword=late asthmatic response (LAR) kn-keyword=late asthmatic response (LAR) END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=7-8 article-no= start-page=811 end-page=823 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=199408 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Induction of renal metallothionein in ischemic acute renal failure in the rat kn-title=ラット虚血性急性腎不全における腎内メタロチオネインの誘導 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To clarify the functions of the renal metallothioneins (MTs) in rats following ischemic acute renal failure, the expression of MT mRNA and the localization of MT in rats undergoing 60 min of bilateral renal artery clamp ischemia followed by reperfusion was examined by Northern blot analysis, in situ hybridization and immunohistochemical analysis. Induction of maximum at 1 to 3 days followed by a gradual decrease. Histlogically, both MT mRNA and MT were detected in renal tubular cells intensely and specifically in the outer medulla at 1 day after release of the clamp. These findings suggest that MTs protect the tubular cells by scavenging the free radicals, which probably cause renal tubular cell damage by ischemia-reperfusion, and that MTs provide the zinc ions to zinc-requiring apo-enzymes necessary for healing and regenerating renal tubular cells. en-copyright= kn-copyright= en-aut-name=HaradaKeiko en-aut-sei=Harada en-aut-mei=Keiko kn-aut-name=原田圭子 kn-aut-sei=原田 kn-aut-mei=圭子 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=虚血性急性腎不全 kn-keyword=虚血性急性腎不全 en-keyword=メタロチオネイン kn-keyword=メタロチオネイン en-keyword=in situ hybridization kn-keyword=in situ hybridization en-keyword=免疫組織化学染色 kn-keyword=免疫組織化学染色 END start-ver=1.4 cd-journal=joma no-vol=108 cd-vols= no-issue=1-2 article-no= start-page=13 end-page=29 dt-received= dt-revised= dt-accepted= dt-pub-year=1996 dt-pub=19960229 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The expansion and antitumoral activity of recombinant IL-2 activated tumor infiltrating lymphocytes from human cancers kn-title=腫瘍内浸潤リンパ球の rIL-2 添加培養と細胞傷害活性の研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tumor infiltrating lymohocytes (TIL) were isolated from various human cancers and cultured.

TIL cultured in 1000u/ml recombinant interleukin-2 (rIL-2) with 20% conditioned medium (CoM) exhibited far better expansion capability than that of TIL cultured in rIL-2 1000u/ml alone, and continued to expand up to 14 weeks. The maximal expansion index (EI) was 23912. When TIL arrested expansion during the culture, the addition of PHA restored the ability to expand. The CoM was composed of spent medium from a 3-day culture of peripheral blood mononuclear cells from cancer patients. The lymphokine-activated killer (LAK) cells induced by the culture was utilized for clinical adoptive immunotherapy in our department. Cytotoxicity against K562 and Daudi target cells was highest at 2 to 3 weeks, and disappeared between 4 and 7 weeks of culture. The phenotype of fresh TIL was mainly CD3(+) T cells, predominantly CD4(+) cells, but CD8(+) cells became predominant in long term culture. The frequency of IL-2R(+) and HLA-DR+ cells was correlated with the expansiveness of TIL. The appearance and intensity of perforin positive cells were associated with the level of cytotoxicity of cultured TIL. en-copyright= kn-copyright= en-aut-name=MatsumotoMitsuaki en-aut-sei=Matsumoto en-aut-mei=Mitsuaki kn-aut-name=松本三明 kn-aut-sei=松本 kn-aut-mei=三明 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一外科学教室 en-keyword=腫瘍内浸潤リンパ球 kn-keyword=腫瘍内浸潤リンパ球 en-keyword=recombinant interleukin-2 kn-keyword=recombinant interleukin-2 en-keyword=細胞傷害活性 kn-keyword=細胞傷害活性 en-keyword=リンパ球表面抗原 kn-keyword=リンパ球表面抗原 en-keyword=パーフォリン kn-keyword=パーフォリン END start-ver=1.4 cd-journal=joma no-vol=108 cd-vols= no-issue=7-8 article-no= start-page=241 end-page=252 dt-received= dt-revised= dt-accepted= dt-pub-year=1996 dt-pub=19960831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Hemodynamic and hormonal changes under the biventricular bypass system with ventricular fibrillated hearts kn-title=心室細動下両心バイパス型人工心臓における循環及び内分泌動態の検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hemodynamic and hormonal changes were studied in 13 sheep whose entire circulation was maintained by a biventricular bypass system with a pair of pusher-plate type blood pumps. Ventricular fibrillation was induced and pneumatically driven pumps placed outside the body kept the animals alive for 2-48 days (average: 11 days). Pump output and aortic pressure stayed within physiological ranges, but central venous pressure was elevated from 5 to 10-13 ㎜Hg after surgery. Serum levels of antidiuretic hormone, cortisol and insulin were stabilized soon after surgery. Adrenaline level and renin activity did not change significantly. For unknown reasons, the noradrenaline level showed a temporary increase after a week. Atrial natriuretic peptide (ANP) increased significantly 5 days after surgery. There were significant drops in triiodothyronine (T(3)) and thyroxine (T(4)) levels after surgery with gradual recovery afterward to 40% and 50% of the control levels, respectively. These results suggested that the biventricular bypass system maintained hemodynamic conditions similar to those maintained by the natural heart, although ANP, T(3) and T(4) values were changed. en-copyright= kn-copyright= en-aut-name=NakayamaHironobu en-aut-sei=Nakayama en-aut-mei=Hironobu kn-aut-name=中山裕宣 kn-aut-sei=中山 kn-aut-mei=裕宣 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二外科学教室 en-keyword=左右非同期 variable rate mode kn-keyword=左右非同期 variable rate mode en-keyword=両心バイパス型人工心臓 kn-keyword=両心バイパス型人工心臓 en-keyword=甲状腺ホルモン kn-keyword=甲状腺ホルモン en-keyword=心房性ナトリウム利尿ペプタイド kn-keyword=心房性ナトリウム利尿ペプタイド END start-ver=1.4 cd-journal=joma no-vol=107 cd-vols= no-issue=7-8 article-no= start-page=91 end-page=98 dt-received= dt-revised= dt-accepted= dt-pub-year=1995 dt-pub=19950831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Immobilization stress affected free radicals, superoxide dismutase activity and thiobarbituric acid reactive substances in the rat brain kn-title=拘束スレレスのラット脳内フリーラジカル, スーパーオキシドジスムターゼ活性およびチオバルビツール酸反応物質への影響に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immobilization stress for 6 hours induced hemorrhagic erosion in the rat stomach. Hydroxyl radicals singnificantly increased in the pons-medulla oblongata in stressed rats. Mitochondrial superoxide dismutase (SOD) activity was enhanced in the midbrain but was lowered in the cortex, hippocampus and cerebellum in stressed rats. Thiobarbituric acid reactive substances increased by stress in the cortex and midbrain. These finding suggested that immobilization stress generated hydroxyl radicals and accelerated lipid peroxidation, and affected mitocho-drial SOD activity which may lead to neuronal damage in stressed rats. en-copyright= kn-copyright= en-aut-name=OkamuraYouko en-aut-sei=Okamura en-aut-mei=Youko kn-aut-name=岡村容子 kn-aut-sei=岡村 kn-aut-mei=容子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部附属分子細胞医学研究施設神経情報学部門 en-keyword=拘束ストレス kn-keyword=拘束ストレス en-keyword=ヒドロキシルラジカル kn-keyword=ヒドロキシルラジカル en-keyword=スーパーオキシドジスムターゼ活性 kn-keyword=スーパーオキシドジスムターゼ活性 en-keyword=チオバルビツール酸反応物質 kn-keyword=チオバルビツール酸反応物質 en-keyword=脳 kn-keyword=脳 END start-ver=1.4 cd-journal=joma no-vol=108 cd-vols= no-issue=3-6 article-no= start-page=65 end-page=69 dt-received= dt-revised= dt-accepted= dt-pub-year=1996 dt-pub=19960629 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Pathogenesis of nystagmus ⑵ Measuring eye movements with video image processing technique kn-title=眼振の病態生理の研究―第2報 ビデオ画像処理による眼球運動計測― en-subtitle= kn-subtitle= en-abstract= kn-abstract=A high speed video system was compared with a conventional video system for measuring saccadic eye movements to evaluate temporal and spatial profiles of these measurements. Video image processing techniques are used to determine the pupil center, and this consequently provided a spatial resolution better than that of one diode of a charge-coupled device (CCD). Although the spatial resolution of both systems is influenced by pupil size and intensity of illumination, spatial resolution in practice is equal to 0.1 to 0.2 degree. Compared to the conventional video system, the high speed video system with a video frame rate of 1000 frames per second offers a marked improvement in temporal resolution for evaluating saccadie eye movements. Each eye being illuminated by an infrared light source with nothing attached to the eye, this video system measurement allows the subject to fixate and follow an object of regard without being disturbed. Therefore, the high speed video recordings and processing techniques have proved to be useful method for analyzing saccadic eye movement. en-copyright= kn-copyright= en-aut-name=OkayamaHideki en-aut-sei=Okayama en-aut-mei=Hideki kn-aut-name=岡山英樹 kn-aut-sei=岡山 kn-aut-mei=英樹 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部眼科学教室 en-keyword=眼球運動計測 kn-keyword=眼球運動計測 en-keyword=高速ビデオシステム kn-keyword=高速ビデオシステム en-keyword=画像処理 kn-keyword=画像処理 END start-ver=1.4 cd-journal=joma no-vol=114 cd-vols= no-issue=2 article-no= start-page=159 end-page=165 dt-received= dt-revised= dt-accepted= dt-pub-year=2002 dt-pub=20020930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Clinical significance of anti-asialoglycoprotein receptor autoantibodies, detected by a capture-immunoassay, in autoimmune liver diseases kn-title=抗原捕捉免疫測定法による抗アシアロ糖タンパク質受容体抗体の検出 ―自己免疫性肝疾患における臨床的意義― en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the development of autoimmune chronic acive hepatitis (AIH), the pathogenic relevance of antimmune responses against asialoglycoprotein recepter (ASGPR) has been implicated. We have previously developed a capture enzyme-linked immunsorbent assay (ELISA) for detection of anti-ASGPR antibodies and found a high prevalence of anti-ASGPR antibodies in AIH and primary biliary cirrhosis (PBC). IN this study, to clarify the clinical singnifi-cance of the measurement of anti-ASGPR antibodies in autimmune live diseases we studied correlations between thee isotype of the anti-ASGPR antibody.In AIH, the anti-ASGPR antibody titer was positively correlated with serum γ-globulin and IgM values, but not with serum transaminase. The anti-ASGPR antibody titer in histogically-active disease with piecmeal necrosis was signififcantly higher then that in quiescent disease. The most common Isotype of anti-ASGPR antibodies detected in active AIH was IgM. We encountered a case of AIH where the tirer of IgM anti-ASGPR antibody decreased by induction of remission with steroid therapy. These results suggest that the measurement of IgM isotope anti-ASGPR antiody might be useful for the evaluation of disease activity and effects of therapy in AIH patients. en-copyright= kn-copyright= en-aut-name=MorisueYoshiko en-aut-sei=Morisue en-aut-mei=Yoshiko kn-aut-name=森末佳子 kn-aut-sei=森末 kn-aut-mei=佳子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=Department of Medicine and Medical Science,Okayama University Graduate School of Medicine and Dentistry en-keyword=自己免疫性肝炎 kn-keyword=自己免疫性肝炎 en-keyword=原発性胆汁性肝硬変 kn-keyword=原発性胆汁性肝硬変 en-keyword=抗アシアロ糖タンパク質受容体抗体 kn-keyword=抗アシアロ糖タンパク質受容体抗体 en-keyword=自己抗体 kn-keyword=自己抗体 en-keyword=アイソタイプ kn-keyword=アイソタイプ END start-ver=1.4 cd-journal=joma no-vol=113 cd-vols= no-issue=3 article-no= start-page=235 end-page=239 dt-received= dt-revised= dt-accepted= dt-pub-year=2001 dt-pub=20011231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=抗体による血液腫瘍の治療 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=谷本光音 kn-aut-sei=谷本 kn-aut-mei=光音 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯学総合研究科 病態制御科学専攻(第二内科) en-keyword=モノクローナル抗体 kn-keyword=モノクローナル抗体 en-keyword=血液腫瘍 kn-keyword=血液腫瘍 en-keyword=CD 20 kn-keyword=CD 20 en-keyword=CD 33 kn-keyword=CD 33 en-keyword=キメラ抗体 kn-keyword=キメラ抗体 END start-ver=1.4 cd-journal=joma no-vol=117 cd-vols= no-issue=3 article-no= start-page=219 end-page=224 dt-received= dt-revised= dt-accepted= dt-pub-year=2006 dt-pub=20060104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Characterization and usefulness of a monoclonal antibody against human herpesvirus-7 DNA polymerase processivity factor kn-title=ヒトヘルペスウイルス7型のDNA ポリメラーゼサブユニットに対する単クローン抗体の性状と有用性 en-subtitle= kn-subtitle= en-abstract= kn-abstract=A monoclonal antibody (MAb), IK17, was developed and found useful for the analysis of human herpesvirus-7 (HHV7) genome replication. In Western blot analysis, the MAb IK17 specifically detected an HHV7 DNA polymerase subunit,U27 protein,expressed in both Escherichia coli (E.Coli)and HHV7-infected cells.Analysis by the same method of truncated U27 proteins expressed in E. Coli demonstrated that the MAb IK17 recognizes an epitope between amino acid 1 and 133 of the U27 protein.The indirect immunofluorescence (IF)method with MAb IK17 detected an unexpected reduction of U27 protein in the infected cells that were treated with a viral DNA polymerase inhibitor,phosphonoacetic acid (PAA),although no reduction of U27 mRNA was observed in the cells by Northern blot analysis. The data suggest the possible usefulness of the MAb IK17 for obtaining clues to characterize an unknown feature of the U27 protein. Immunoprecipitation experiments with the MAb IK17 enabled to detect at least four U27 protein-associated phosphorylated polypeptides in addition to the U27 protein itself.The result indicates the usefulness of the MAb IK17 for qualitative and quantitative analysis of the U27 proteinassociated viral and cellular factors. These analyses contribute to elucidation of the HHV7 genome replication system. en-copyright= kn-copyright= en-aut-name=NambaHikaru en-aut-sei=Namba en-aut-mei=Hikaru kn-aut-name=難波ひかる kn-aut-sei=難波 kn-aut-mei=ひかる 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 病原ウイルス学 en-keyword=ヒトヘルペスウイルス7型 (Human Herpesvirus-7) kn-keyword=ヒトヘルペスウイルス7型 (Human Herpesvirus-7) en-keyword=DNA polymerase processivity factor kn-keyword=DNA polymerase processivity factor en-keyword=単クローン抗体 (monoclonal antibody) kn-keyword=単クローン抗体 (monoclonal antibody) END start-ver=1.4 cd-journal=joma no-vol=117 cd-vols= no-issue=3 article-no= start-page=199 end-page=204 dt-received= dt-revised= dt-accepted= dt-pub-year=2006 dt-pub=20060104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=ヒストンアセチル化制御による実験的関節炎の抑制 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=西田圭一郎 kn-aut-sei=西田 kn-aut-mei=圭一郎 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 人体構成学 en-keyword=関節リウマチ kn-keyword=関節リウマチ en-keyword=エピジェネティクス kn-keyword=エピジェネティクス en-keyword=ヒストン脱アセチル化酵素阻害剤 kn-keyword=ヒストン脱アセチル化酵素阻害剤 en-keyword=CDKインヒビター kn-keyword=CDKインヒビター en-keyword=抗II型コラーゲン抗体誘導関節炎 kn-keyword=抗II型コラーゲン抗体誘導関節炎 END start-ver=1.4 cd-journal=joma no-vol=116 cd-vols= no-issue=3 article-no= start-page=215 end-page=220 dt-received= dt-revised= dt-accepted= dt-pub-year=2005 dt-pub=20050131 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=新しい核内受容体 Pregnane X Receptor の生殖生理における役割―岡山大学医学賞(林原賞)を受賞して― en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=増山寿 kn-aut-sei=増山 kn-aut-mei=寿 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部・歯学部附属病院 産科婦人科 en-keyword=pregnane X receptor kn-keyword=pregnane X receptor en-keyword=steroidogenesis kn-keyword=steroidogenesis en-keyword=cytochrome P450 kn-keyword=cytochrome P450 en-keyword=drug resistance kn-keyword=drug resistance END start-ver=1.4 cd-journal=joma no-vol=117 cd-vols= no-issue=2 article-no= start-page=109 end-page=118 dt-received= dt-revised= dt-accepted= dt-pub-year=2005 dt-pub=20050901 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=誘導性ヒスタミンはH(2)受容体刺激を介してP.ances-LPS 誘発性肝炎からマウスを保護する en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=横山穣 kn-aut-sei=横山 kn-aut-mei=穣 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薬理学 en-keyword=内因性ヒスタミン kn-keyword=内因性ヒスタミン en-keyword=サイトカイン kn-keyword=サイトカイン en-keyword=マウス急性肝炎 kn-keyword=マウス急性肝炎 END
