However, there is still controversy concerning which serological markers can predict spinal SSI. This study aims to evaluate excellent and early indicators for detecting SSI, focusing on spine instrumented surgery. Materials and Methods: This study included 268 patients who underwent spinal instrumented surgery from January 2022 to December 2023 (159 female and 109 male, average 62.9 years). The SSI group included 20 patients, and the non-SSI group comprised 248 patients. Surgical time, intraoperative blood loss, and glycemic levels were measured in both groups. The complete blood cell counts, differential counts, albumin, and C-reactive protein (CRP) levels were measured pre-surgery and postoperative on Days 1, 3, and 7. In comparing the groups, the Mann?Whitney U test analysis was used for continuous variables, while the chi-squared test and Fisher’s exact test were used for dichotomous variables. Results: The incidence of SSI after spinal instrumentation was 7.46% and was relatively higher in scoliosis surgery. The SSI group had significantly longer surgical times (248 min vs. 180 min, p = 0.0004) and a higher intraoperative blood loss (772 mL vs. 372 mL, p < 0.0001) than the non-SSI group. In the SSI group, the Day 3 (10.5 ± 6.2% vs. 13.8 ± 6.0%, p = 0.012) and Day 7 (14.4 ± 4.8% vs. 18.8 ± 7.1%, p = 0.012) lymphocyte ratios were lower than the non-SSI group. Albumin levels on Day 1 in the SSI group were lower than in the non-SSI group (2.94 ± 0.30 mg/dL vs. 3.09 ± 0.38 mg/dL, p = 0.045). There is no difference in CRP and lymphocyte count between the two groups. Conclusions: SSI patients had lower lymphocyte percentages than non-SSI patients, which was a risk factor for SSI, with constant high inflammation. The Day 3 lymphocyte percentage may predict SSI after spinal instrumented surgery. en-copyright= kn-copyright= en-aut-name=MiyamotoAkiyoshi en-aut-sei=Miyamoto en-aut-mei=Akiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FloresAngel Oscar Paz en-aut-sei=Flores en-aut-mei=Angel Oscar Paz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YuDongwoo en-aut-sei=Yu en-aut-mei=Dongwoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=JainMukul en-aut-sei=Jain en-aut-mei=Mukul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HengChristan en-aut-sei=Heng en-aut-mei=Christan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KomatsubaraTadashi en-aut-sei=Komatsubara en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AratakiShinya en-aut-sei=Arataki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=ShinoharaKensuke en-aut-sei=Shinohara en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= en-keyword=surgical site infection kn-keyword=surgical site infection en-keyword=spine surgery kn-keyword=spine surgery en-keyword=instrumentation kn-keyword=instrumentation en-keyword=diagnosis kn-keyword=diagnosis en-keyword=lymphocyte kn-keyword=lymphocyte END start-ver=1.4 cd-journal=joma no-vol=351 cd-vols= no-issue= article-no= start-page=199522 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evidence for the replication of a plant rhabdovirus in its arthropod mite vector en-subtitle= kn-subtitle= en-abstract= kn-abstract=Transmission of plant viruses that replicate in the insect vector is known as persistent-propagative manner. However, it remains unclear whether such virus-vector relationships also occur between plant viruses and other biological vectors such as arthropod mites. In this study, we investigated the possible replication of orchid fleck virus (OFV), a segmented plant rhabdovirus, within its mite vector (Brevipalpus californicus s.l.) using quantitative RT-qPCR, western blotting and next-generation sequencing. Time-course RT-qPCR and western blot analyses showed an increasing OFV accumulation pattern in mites after virus acquisition. Since OFV genome expression requires the transcription of polyadenylated mRNAs, polyadenylated RNA fractions extracted from the viruliferous mite samples and OFV-infected plant leaves were used for RNA-seq analysis. In the mite and plant datasets, a large number of sequence reads were aligned to genomic regions of OFV RNA1 and RNA2 corresponding to transcribed viral gene mRNAs. This includes the short polyadenylated transcripts originating from the leader and trailer regions at the ends of the viral genome, which are believed to play a crucial role in viral transcription/replication. In contrast, a low number of reads were mapped to the non-transcribed regions (gene junctions). These results strongly suggested that OFV gene expression occurs both in mites and plants. Additionally, deep sequencing revealed the accumulation of OFV-derived small RNAs in mites, although their size profiles differ from those found in plants. Taken together, our results indicated that OFV replicates within a mite vector and is targeted by the RNA-silencing mechanism. en-copyright= kn-copyright= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujitaMiki en-aut-sei=Fujita en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TelengechPaul en-aut-sei=Telengech en-aut-mei=Paul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaruyamKazuyuki en-aut-sei=Maruyam en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HyodoKiwamu en-aut-sei=Hyodo en-aut-mei=Kiwamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TassiAline Daniele en-aut-sei=Tassi en-aut-mei=Aline Daniele kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OchoaRonald en-aut-sei=Ochoa en-aut-mei=Ronald kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AndikaIda Bagus en-aut-sei=Andika en-aut-mei=Ida Bagus kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SuzukiNobuhiro en-aut-sei=Suzuki en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=6 en-affil=Tropical Research and Education Center, University of Florida kn-affil= affil-num=7 en-affil=Systematic Entomology Laboratory, USDA kn-affil= affil-num=8 en-affil=College of Plant Protection, Northwest A&F University kn-affil= affil-num=9 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= en-keyword=Rhabdovirus kn-keyword=Rhabdovirus en-keyword=Plant kn-keyword=Plant en-keyword=Mite kn-keyword=Mite en-keyword=Vector kn-keyword=Vector en-keyword=Replication kn-keyword=Replication en-keyword=mRNA kn-keyword=mRNA en-keyword=Small RNA kn-keyword=Small RNA END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=5 article-no= start-page=489 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250430 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mutagenesis Targeting the S153 Residue Within the Transmembrane β-Hairpin of Mosquito-Larvicidal Mpp46Ab Affects Its Toxicity and the Synergistic Toxicity with Cry4Aa en-subtitle= kn-subtitle= en-abstract= kn-abstract=We constructed a library of Mpp46Ab mutants, in which S153 within the transmembrane β-hairpin was randomly replaced by other amino acids. Mutagenesis and subsequent primary screening yielded 10 different Mpp46Ab mutants in addition to the wild type. Remarkably, S153 was replaced with a more hydrophobic amino acid in most of the mutants, and the S153I mutant in particular exhibited significantly increased toxicity. Electrophysiologic analysis using artificial lipid bilayers revealed that the single-channel conductance and PK/PCl permeability ratio were significantly increased for S153I pores. This suggests that the formation of highly ion-permeable and highly cation-selective toxin pores increases the influx of cations and water into cells, thereby facilitating osmotic shock. In addition, the S153F, S153L, and S153I mutants exhibited significantly reduced synergistic toxicity with Cry4Aa. Electrophysiologic analysis showed that the S153F, S153L, and S153I mutants form toxin pores with a significantly reduced PK/PNa permeability ratio and a significantly increased PK/PCa permeability ratio compared to wild-type pores. Thus, our results suggest that pore formation is central to the insecticidal activity of Mpp46Ab and that the ion permeability of toxin pores is a potential indicator correlated with both toxicity and synergistic toxicity with other toxins. en-copyright= kn-copyright= en-aut-name=HayakawaTohru en-aut-sei=Hayakawa en-aut-mei=Tohru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamaokaSyun en-aut-sei=Yamaoka en-aut-mei=Syun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AsakuraMami en-aut-sei=Asakura en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiranoMinako en-aut-sei=Hirano en-aut-mei=Minako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IdeToru en-aut-sei=Ide en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Bacillus thuringiensis kn-keyword=Bacillus thuringiensis en-keyword=mosquito-larvicidal proteins kn-keyword=mosquito-larvicidal proteins en-keyword=synergistic toxicity kn-keyword=synergistic toxicity en-keyword=Culex pipiens mosquito larvae kn-keyword=Culex pipiens mosquito larvae en-keyword=side-directed mutagenesis kn-keyword=side-directed mutagenesis en-keyword=electrophysiologic analysis kn-keyword=electrophysiologic analysis END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=環境中親電子物質によるDNAメチル化制御を介したケモカイン発現誘導機構 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=TSUCHIDATomoki en-aut-sei=TSUCHIDA en-aut-mei=Tomoki kn-aut-name=土田知貴 kn-aut-sei=土田 kn-aut-mei=知貴 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=小胞体ストレスセンサー IRE1α に対する S-ニトロシル化阻害薬の同定とその薬効評価 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KUROGIHaruna en-aut-sei=KUROGI en-aut-mei=Haruna kn-aut-name=黒木春那 kn-aut-sei=黒木 kn-aut-mei=春那 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=歯周組織再生療法における塩基性線維芽細胞増殖因子製剤投与と自家骨移植の効果を比較した後ろ向きコホート研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MATSUMOTOToshiki en-aut-sei=MATSUMOTO en-aut-mei=Toshiki kn-aut-name=松本俊樹 kn-aut-sei=松本 kn-aut-mei=俊樹 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=20 article-no= start-page=eadv7488 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250516 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structure of a photosystem I supercomplex from Galdieria sulphuraria close to an ancestral red alga en-subtitle= kn-subtitle= en-abstract= kn-abstract=Red algae exhibit unique photosynthetic adaptations, characterized by photosystem I (PSI) supercomplexes containing light-harvesting complexes (LHCs), forming PSI-LHCI supercomplexes. In this study, we solved the PSI-LHCI structure of Galdieria sulphuraria NIES-3638 at 2.19-angstrom resolution using cryo-electron microscopy, revealing a PSI monomer core associated with seven LHCI subunits. Structural analysis uncovered the absence of phylloquinones, the common secondary electron acceptor in PSI of photosynthetic organisms, suggesting adaptation to a benzoquinone-like molecule. Phylogenetic analysis suggests that G. sulphuraria retains traits characteristic of an ancestral red alga, including distinctive LHCI binding and interaction patterns. Variations in LHCI composition and interactions across red algae, particularly in red-lineage chlorophyll a/b-binding-like protein and red algal LHCs, highlight evolutionary divergence and specialization. These findings not only deepen our understanding of red algal PSI-LHCI diversification but also enable us to predict features of an ancestral red algal PSI-LHCI supercomplex, providing a framework to explore evolutionary adaptations from an ancestral red alga. en-copyright= kn-copyright= en-aut-name=KatoKoji en-aut-sei=Kato en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KumazawaMinoru en-aut-sei=Kumazawa en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakajimaYoshiki en-aut-sei=Nakajima en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuzukiTakehiro en-aut-sei=Suzuki en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DohmaeNaoshi en-aut-sei=Dohmae en-aut-mei=Naoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShenJian-Ren en-aut-sei=Shen en-aut-mei=Jian-Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IfukuKentaro en-aut-sei=Ifuku en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NagaoRyo en-aut-sei=Nagao en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Research institute for interdisciplinary Science and Graduate School of environ-mental, life, natural Science and technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=3 en-affil=Research institute for interdisciplinary Science and Graduate School of environ-mental, life, natural Science and technology, Okayama University kn-affil= affil-num=4 en-affil=Biomolecular characterization Unit, RiKen center for Sustainable Resource Science kn-affil= affil-num=5 en-affil=Biomolecular characterization Unit, RiKen center for Sustainable Resource Science kn-affil= affil-num=6 en-affil=Research institute for interdisciplinary Science and Graduate School of environ-mental, life, natural Science and technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=8 en-affil=Faculty of Agriculture, Shizuoka University kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Supplement-induced acute kidney injury reproduced in kidney organoids en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Acute kidney injury associated with the consumption of Beni-koji CholesteHelp supplements, which contain red yeast rice (Beni-Koji), has become a significant public health concern in Japan. While renal biopsy findings from several case reports have suggested tubular damage, no definitive causal relationship has been established, and the underlying mechanisms of kidney injury remain poorly understood. The complexity of identifying toxic substances in supplements containing various bioactive compounds makes conventional investigative approaches both time-consuming and challenging. This highlights an urgent need to establish a reliable platform for assessing organ-specific toxicity in such supplements. In this study, we utilized a kidney organoid model derived from adult rat kidney stem cells (KS cells) to assess the potential tubular toxicity of these supplements. Methods: KS cell clusters were cultured in three-dimensional system supplemented with growth factors to promote kidney organoids. The organoids were subsequently exposed to Beni-koji CholesteHelp supplements or cisplatin, followed by histological and molecular analyses to evaluate structural impacts. Results: Established organoids had the kidney-like structures including tubular-like structures and glomerulus-like structures at the tips of multiple tubules. Treatment with Beni-koji CholesteHelp supplements induced significant tubular damage in the organoids, characterized by epithelial cell thinning, structural disruption, and increase in cleaved-caspase 3-positive apoptotic tubular cells, similar to the organoids treated with cisplatin. Conclusion: These findings provide the first evidence suggesting that certain toxicants in specific batches of Beni-koji CholesteHelp supplements cause direct renal tubular injury. This KS cell-based organoid system represents a cost-effective, reproducible, and technically simple platform for nephrotoxicity screening. en-copyright= kn-copyright= en-aut-name=NakanohHiroyuki en-aut-sei=Nakanoh en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujiKenji en-aut-sei=Tsuji en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukushimaKazuhiko en-aut-sei=Fukushima en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HaraguchiSoichiro en-aut-sei=Haraguchi en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KitamuraShinji en-aut-sei=Kitamura en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Acute kidney injury kn-keyword=Acute kidney injury en-keyword=Drug-induced nephrotoxicity kn-keyword=Drug-induced nephrotoxicity en-keyword=Kidney organoid kn-keyword=Kidney organoid en-keyword=Kidney stem cell kn-keyword=Kidney stem cell END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=7 article-no= start-page=192 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250509 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=HIF-PH inhibitors induce pseudohypoxia in T cells and suppress the growth of microsatellite stable colorectal cancer by enhancing antitumor immune responses en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Recent studies have revealed that CD8+ T cells can be activated via genetic upregulation of HIF-1 alpha, thereby augmenting antitumor effector functions. HIF-1 alpha upregulation can be attained by inhibiting HIF-prolyl hydroxylase (HIF-PH) under normoxic conditions, termed pseudohypoxia. This study investigated whether pseudohypoxia induced by HIF-PH inhibitors suppresses Microsatellite stable (MSS) colorectal cancer (CRC) by affecting tumor immune response.
Methods The HIF-PH inhibitors Roxadustat and Vadadustat were utilized in this study. In vitro, we assessed the effects of HIF-PH inhibitors on human and murine colon cancer cell lines (SW480, HT29, Colon26) and murine T cells. In vivo experiments were performed with mice bearing Colon26 tumors to evaluate the effect of these inhibitors on tumor immune responses. Tumor and spleen samples were analyzed using immunohistochemistry, RT-qPCR, and flow cytometry to elucidate potential mechanisms.
Results HIF-PH inhibitors demonstrated antitumor effects in vivo but not in vitro. These inhibitors enhanced the tumor immune response by increasing the infiltration of CD8+ and CD4+ tumor-infiltrating lymphocytes (TILs). HIF-PH inhibitors induced IL-2 production in splenic and intratumoral CD4+ T cells, promoting T cell proliferation, differentiation, and immune responses. Roxadustat synergistically enhanced the efficacy of anti-PD-1 antibody for MSS cancer by increasing the recruitment of TILs and augmenting effector-like CD8+ T cells.
Conclusion Pseudohypoxia induced by HIF-PH inhibitors activates antitumor immune responses, at least in part, through the induction of IL-2 secretion from CD4+ T cells in the spleen and tumor microenvironment, thereby enhancing immune efficacy against MSS CRC. en-copyright= kn-copyright= en-aut-name=ChenYuehua en-aut-sei=Chen en-aut-mei=Yuehua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamadaYusuke en-aut-sei=Hamada en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangYuze en-aut-sei=Wang en-aut-mei=Yuze kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TianMiao en-aut-sei=Tian en-aut-mei=Miao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TazawaHiroshi en-aut-sei=Tazawa en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujisawaMasayoshi en-aut-sei=Fujisawa en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YoshimuraTeizo en-aut-sei=Yoshimura en-aut-mei=Teizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Colorectal cancer kn-keyword=Colorectal cancer en-keyword=Microsatellite stable kn-keyword=Microsatellite stable en-keyword=Hypoxia-inducible factor kn-keyword=Hypoxia-inducible factor en-keyword=Immune checkpoint inhibitors kn-keyword=Immune checkpoint inhibitors END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=14323 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250424 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lymphatic flow dynamics under exercise load assessed with thoracic duct ultrasonography en-subtitle= kn-subtitle= en-abstract= kn-abstract=The thoracic duct (TD) is the largest lymphatic vessel proximal to the venous system. It undergoes morphological changes in response to lymph flow from the periphery, with automatic contraction controlling the dynamics to propel lymph toward the venous system. Recent advancements in ultrasonography have facilitated non-invasive observations of the TD’s terminal, including its valve and wall motions. Observations of TD movements allow predictions of lymphatic flow dynamics. However, no studies have yet documented the changes in the TD under exercise-induced lymph flow enhancement in humans. Here, using 18-MHz high-frequency ultrasonography, we demonstrate for the first time that the TD diameter significantly expands under exercise load. This study analyzed 20 participants; the maximum TD diameters at rest and post-exercise were 2.69?±?1.06 mm and 3.41?±?1.32 mm, respectively (p?=?0.00000056). While various methods exist for observing the TD, our approach?dynamically monitoring the TD diameter using sonography in real time and correlating it with lymphatic flow dynamics?offers a novel contribution. en-copyright= kn-copyright= en-aut-name=ShinaokaAkira en-aut-sei=Shinaoka en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimataYoshihiro en-aut-sei=Kimata en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Lymphatics and Edematology, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Plastic and Reconstructive surgery, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= en-keyword=Lymphedema kn-keyword=Lymphedema en-keyword=Lymphatic function kn-keyword=Lymphatic function en-keyword=Lymph flow kn-keyword=Lymph flow en-keyword=Chylothorax kn-keyword=Chylothorax en-keyword=Chylous ascites,lymph velocity kn-keyword=Chylous ascites,lymph velocity END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=2323 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A mini-hairpin shaped nascent peptide blocks translation termination by a distinct mechanism en-subtitle= kn-subtitle= en-abstract= kn-abstract=Protein synthesis by ribosomes produces functional proteins but also serves diverse regulatory functions, which depend on the coding amino acid sequences. Certain nascent peptides interact with the ribosome exit tunnel to arrest translation and modulate themselves or the expression of downstream genes. However, a comprehensive understanding of the mechanisms of such ribosome stalling and its regulation remains elusive. In this study, we systematically screen for unidentified ribosome arrest peptides through phenotypic evaluation, proteomics, and mass spectrometry analyses, leading to the discovery of the arrest peptides PepNL and NanCL in E. coli. Our cryo-EM study on PepNL reveals a distinct arrest mechanism, in which the N-terminus of PepNL folds back towards the tunnel entrance to prevent the catalytic GGQ motif of the release factor from accessing the peptidyl transferase center, causing translation arrest at the UGA stop codon. Furthermore, unlike sensory arrest peptides that require an arrest inducer, PepNL uses tryptophan as an arrest inhibitor, where Trp-tRNATrp reads through the stop codon. Our findings illuminate the mechanism and regulatory framework of nascent peptide-induced translation arrest, paving the way for exploring regulatory nascent peptides. en-copyright= kn-copyright= en-aut-name=AndoYushin en-aut-sei=Ando en-aut-mei=Yushin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KoboAkinao en-aut-sei=Kobo en-aut-mei=Akinao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NiwaTatsuya en-aut-sei=Niwa en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamakawaAyako en-aut-sei=Yamakawa en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KonomaSuzuna en-aut-sei=Konoma en-aut-mei=Suzuna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KobayashiYuki en-aut-sei=Kobayashi en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NurekiOsamu en-aut-sei=Nureki en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TaguchiHideki en-aut-sei=Taguchi en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ItohYuzuru en-aut-sei=Itoh en-aut-mei=Yuzuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ChadaniYuhei en-aut-sei=Chadani en-aut-mei=Yuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Biological Sciences, Graduate School of Science, The University of Tokyo kn-affil= affil-num=2 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=3 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=4 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=5 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=6 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=7 en-affil=Department of Biological Sciences, Graduate School of Science, The University of Tokyo kn-affil= affil-num=8 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=9 en-affil=Department of Biological Sciences, Graduate School of Science, The University of Tokyo kn-affil= affil-num=10 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=65 end-page=73 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between the Pretreatment Body Mass Index and Anamorelin’s Efficacy in Patients with Cancer Cachexia: A Retrospective Cohort Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Anamorelin (ANAM) is used to treat cancer-associated cachexia, a syndrome involving muscle loss and anorexia. The timing of the initiation of ANAM treatment is crucial to its efficacy. Although the body mass index (BMI) is a diagnostic criterion for cancer cachexia, no studies have explored its association with ANAM efficacy. We conducted a single-center, retrospective cohort study to investigate the association between the pre-treatment BMI and ANAM efficacy in patients with cancer-associated cachexia (n=47). The ANAM treatment was considered effective if the patient’s appetite improved within 30 days of treatment initiation. We calculated a BMI cutoff value (19.5 kg/m2) and used it to divide the patients into high- and low-BMI groups. Their background, clinical laboratory values, cancer types, and treatment lines were investigated. Twenty (42.6%) had a high BMI (? 19.5 kg/m2) and 27 (57.4%) had a low BMI (< 19.5 kg/m2). High BMI was significantly associated with ANAM effectiveness (odds ratio 7.86, 95% confidence interval 1.99-31.00, p=0.003). Together these results indicate that it is beneficial to initiate ANAM treatment before a patient’s BMI drops below 19.5 kg/m2. Our findings will help advance cancer cachexia treatment and serve as a reference for clinicians to predict ANAM’s efficacy. en-copyright= kn-copyright= en-aut-name=MakiMasatoshi en-aut-sei=Maki en-aut-mei=Masatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakadaRyo en-aut-sei=Takada en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshigoTomoyuki en-aut-sei=Ishigo en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiwaraMiki en-aut-sei=Fujiwara en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahashiYoko en-aut-sei=Takahashi en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtsukaShinya en-aut-sei=Otsuka en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TamuraKoji en-aut-sei=Tamura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HamaokaTerutaka en-aut-sei=Hamaoka en-aut-mei=Terutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=2 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=3 en-affil=Department of Pharmacy, Sapporo Medical University Hospital kn-affil= affil-num=4 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=5 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=6 en-affil=Department of Surgery, NHO Fukuyama Medical Center kn-affil= affil-num=7 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=8 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= en-keyword=anamorelin kn-keyword=anamorelin en-keyword=cancer-associated cachexia kn-keyword=cancer-associated cachexia en-keyword=body mass index kn-keyword=body mass index en-keyword=albumin kn-keyword=albumin en-keyword=efficacy rate kn-keyword=efficacy rate END start-ver=1.4 cd-journal=joma no-vol=111 cd-vols= no-issue=6 article-no= start-page=064502 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250204 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Josephson effect and odd-frequency pairing in superconducting junctions with unconventional magnets en-subtitle= kn-subtitle= en-abstract= kn-abstract=We consider Josephson junctions formed by coupling two conventional superconductors via an unconventional magnet and investigate the formation of Andreev bound states, their impact on the Josephson effect, and the emergent superconducting correlations. In particular, we focus on unconventional magnets known as ?-wave altermagnets and ?-wave magnets. We find that the Andreev bound states in ?-wave altermagnet and ??-wave magnet Josephson junctions strongly depend on the transverse momentum, with a spin splitting and low-energy minima as a function of the superconducting phase difference ?. In contrast, the Andreev bound states for ??-wave magnets are insensitive to the transverse momentum. We then show that the Andreev bound states can be probed by the local density of states in the middle of the junction, which also reveals that ??2??2- and ?-wave magnet junctions are prone to host zero energy peaks. While the zero-energy peak in ??2??2-wave altermagnet junctions tends to oscillate with the magnetic order, it remains robust in ?-wave magnet junctions. We then discover that the Josephson current in ?-wave altermagnet junctions is composed of higher harmonics of ?, which originate a ?-Josephson junction behavior entirely controlled by the magnetic order in ????-wave altermagnets. In contrast, the Josephson current in Josephson junctions with ?-wave magnets exhibits a conventional sinelike profile with a fast sign change at ?=? due to zero-energy Andreev bound states. We also demonstrate that the critical currents in ?-wave altermagnet Josephson junctions exhibit an oscillatory decay with the increase of the magnetic order, while the oscillations are absent in ?-wave magnet junctions albeit the currents exhibit a slow decay. Furthermore, we also demonstrate that the interplay of the Josephson effect and unconventional magnetic order of ?-wave altermagnets and ?-wave magnets originates from odd-frequency spin-triplet ?-wave superconducting correlations that are otherwise absent. Our results can serve as a guide to pursue the new functionality of Josephson junctions based on unconventional magnets. en-copyright= kn-copyright= en-aut-name=FukayaYuri en-aut-sei=Fukaya en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaKazuki en-aut-sei=Maeda en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YadaKeiji en-aut-sei=Yada en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=CayaoJorge en-aut-sei=Cayao en-aut-mei=Jorge kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaYukio en-aut-sei=Tanaka en-aut-mei=Yukio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=LuBo en-aut-sei=Lu en-aut-mei=Bo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Faculty of Environmental Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Applied Physics, Nagoya University kn-affil= affil-num=3 en-affil=Department of Applied Physics, Nagoya University kn-affil= affil-num=4 en-affil=Department of Physics and Astronomy, Uppsala University kn-affil= affil-num=5 en-affil=Department of Applied Physics, Nagoya University kn-affil= affil-num=6 en-affil=Center for Joint Quantum Studies, Tianjin Key Laboratory of Low Dimensional Materials Physics and Preparing Technology, Department of Physics, Tianjin University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=63 cd-vols= no-issue=21 article-no= start-page=2875 end-page=2884 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Endoscopic and Histological Gastritis in University Students with Helicobacter pylori Infection en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective Although the characteristics of Helicobacter pylori infection have been extensively reported, there is a lack of consensus regarding its characteristics in young adults. The present study examined the endoscopic and histological characteristics of young adults who underwent eradication therapy for H. pylori infection.
Methods We examined the H. pylori infection status of first-year students at Okayama University School of Medicine and Dentistry between 2014 and 2020. A total of 152 (6.8%) students who were positive for H. pylori antibody or pepsinogen tests were enrolled in the study. Among them, 107 students underwent endoscopy, and their biopsy samples were investigated. Seventy-five students were diagnosed with H. pylori infections.
Results Of 75 H. pylori-positive patients, 57 (76.0%) had endoscopic atrophic gastritis, and 42 (56.0%) had histological atrophy. A few patients had severe atrophic gastritis. All 65 patients who underwent an eradication assessment were successfully treated. After successful eradication, 26 patients underwent endoscopic follow-up. The mean follow-up period was 32.9 months. A histological evaluation revealed that gastric antrum atrophy had subsided in 11 of 14 patients, and atrophy in the lesser curvature of the gastric body had subsided in 7 of 8 patients.
Conclusion More than half of young adults with H. pylori infection had atrophic gastritis. We found mild atrophy in young adults, which subsided shortly after eradication treatment. This study provides a foundation for future studies to evaluate the validity of eradication therapy in preventing gastric cancer in patients. en-copyright= kn-copyright= en-aut-name=OkanoueShotaro en-aut-sei=Okanoue en-aut-mei=Shotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakaeHiroyuki en-aut-sei=Sakae en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YokotaKenji en-aut-sei=Yokota en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ObayashiYuka en-aut-sei=Obayashi en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AbeMakoto en-aut-sei=Abe en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KonoYoshiyasu en-aut-sei=Kono en-aut-mei=Yoshiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KanzakiHiromitsu en-aut-sei=Kanzaki en-aut-mei=Hiromitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KawaharaYoshiro en-aut-sei=Kawahara en-aut-mei=Yoshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YanaiHiroyuki en-aut-sei=Yanai en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University 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 Bacteriology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Practical Gastrointestinal Endoscopy, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=atrophic gastritis kn-keyword=atrophic gastritis en-keyword=gastric cancer kn-keyword=gastric cancer en-keyword=Helicobacter pylori kn-keyword=Helicobacter pylori en-keyword=young adults kn-keyword=young adults en-keyword=eradication kn-keyword=eradication END start-ver=1.4 cd-journal=joma no-vol=136 cd-vols= no-issue=3 article-no= start-page=135 end-page=138 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Drug interaction (61.

Selective and efficient CO2 fixation processes are still challenging because of the kinetic and thermodynamic stability of CO2. Among various CO2 fixation processes, the ring-opening copolymerization (ROCOP) of epoxides and CO2 gives aliphatic polycarbonates with high atom economy, although the chemical and physical properties of the resulting polycarbonates are not necessarily satisfactory. Introducing the third monomers into this ROCOP system provides new terpolymers, and the thermal, optical, mechanical or degradation properties can be added or tuned by incorporating new polymer backbones derived from the third monomers at the expense of the CO2 content. Here we review the terpolymerization reactions of epoxides, CO2, and the third monomers such as cyclic anhydrides, lactones, lactides, heteroallenes, and olefins. The development of catalysts and the control of the polymer structures are described together with the chemical and physical properties of the resulting polymers. en-copyright= kn-copyright= en-aut-name=NakaokaKoichi en-aut-sei=Nakaoka en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EmaTadashi en-aut-sei=Ema en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=線維化を伴う膵がん微小環境の立体培養法による新規in vitroモデルの構築と解析 kn-title=Establishment and Analysis of Novel In Vitro 3D Cell Culture Models of the Fibrotic Tumor Microenvironment in Pancreatic Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=TANAKAHiroyoshi en-aut-sei=TANAKA en-aut-mei=Hiroyoshi kn-aut-name=田中啓祥 kn-aut-sei=田中 kn-aut-mei=啓祥 aut-affil-num=1 ORCID= affil-num=1 en-affil=Okayama University kn-affil=岡山大学大学院 END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=22 article-no= start-page=11942 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241106 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Distribution and Incorporation of Extracellular Vesicles into Chondrocytes and Synoviocytes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Osteoarthritis (OA) is a chronic disease affecting over 500 million people worldwide. As the population ages and obesity rates rise, the societal burden of OA is increasing. Pro-inflammatory cytokines, particularly interleukin-1β, are implicated in the pathogenesis of OA. Recent studies suggest that crosstalk between cartilage and synovium contributes to OA development, but the mechanisms remain unclear. Extracellular vesicles (EVs) were purified from cell culture-conditioned medium via ultracentrifugation and confirmed using transmission electron microscopy, nanoparticle tracking analysis, and western blotting. We demonstrated that EVs were taken up by human synoviocytes and chondrocytes in vitro, while in vivo experiments revealed that fluorescent-labelled EVs injected into mouse joints were incorporated into chondrocytes and synoviocytes. EV uptake was significantly inhibited by dynamin-mediated endocytosis inhibitors, indicating that endocytosis plays a major role in this process. Additionally, co-culture experiments with HEK-293 cells expressing red fluorescent protein (RFP)-tagged CD9 and the chondrocytic cell line OUMS-27 confirmed the transfer of RFP-positive EVs across a 600-nm but not a 30-nm filter. These findings suggest that EVs from chondrocytes are released into joint fluid and taken up by cells within the cartilage, potentially facilitating communication between cartilage and synovium. The results underscore the importance of EVs in OA pathophysiology. en-copyright= kn-copyright= en-aut-name=OhtsukiTakashi en-aut-sei=Ohtsuki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoIkumi en-aut-sei=Sato en-aut-mei=Ikumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakashitaRen en-aut-sei=Takashita en-aut-mei=Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KodamaShintaro en-aut-sei=Kodama en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IkemuraKentaro en-aut-sei=Ikemura en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OpokuGabriel en-aut-sei=Opoku en-aut-mei=Gabriel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WatanabeShogo en-aut-sei=Watanabe en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=YamadaHiroshi en-aut-sei=Yamada en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AndoMitsuru en-aut-sei=Ando en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AkiyoshiKazunari en-aut-sei=Akiyoshi en-aut-mei=Kazunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NishidaKeiichiro en-aut-sei=Nishida en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=HirohataSatoshi en-aut-sei=Hirohata en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Neuroscience, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Laboratory of Biomaterials, Institute for Life and Medical Sciences, Kyoto University kn-affil= affil-num=11 en-affil=Department of Immunology, Graduate School of Medicine, Kyoto University kn-affil= affil-num=12 en-affil=Department of Orthopedic Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=13 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=extracellular vesicles (EVs) kn-keyword=extracellular vesicles (EVs) en-keyword=chondrocytes kn-keyword=chondrocytes en-keyword=synoviocytes kn-keyword=synoviocytes en-keyword=osteoarthritis (OA) kn-keyword=osteoarthritis (OA) END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=70 article-no= start-page=e202402690 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241105 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=MoSe2-Sensitized Water Splitting Assisted by C60-Dendrons on the Basal Surface en-subtitle= kn-subtitle= en-abstract= kn-abstract=To facilitate water splitting using MoSe2 as a light absorber, we fabricated water-dispersible MoSe2/C60-dendron nanohybrids via physical modification of the basal plane of MoSe2. Upon photoirradiation, the mixed-dimension MoSe2/C60 (2D/0D) heterojunction generates a charge-separated state (MoSe2?+/C60??) through electron extraction from the exciton in MoSe2 to C60. This process is followed by the hydrogen evolution reaction (HER) from water in the presence of a sacrificial donor (1-benzyl-1,4-dihydronicotinamide) and co-catalyst (Pt-PVP). The apparent quantum yields of the HER were estimated to be 0.06?% and 0.27?% upon photoexcitation at the A- and B-exciton absorption peaks (λmax=800 and 700?nm), respectively. en-copyright= kn-copyright= en-aut-name=TajimaTomoyuki en-aut-sei=Tajima en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuuraTomoki en-aut-sei=Matsuura en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EfendiArif en-aut-sei=Efendi en-aut-mei=Arif kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YukimotoMariko en-aut-sei=Yukimoto en-aut-mei=Mariko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakaguchiYutaka en-aut-sei=Takaguchi en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Materials Design and Engineering, University of Toyama kn-affil= affil-num=4 en-affil=Department of Materials Design and Engineering, University of Toyama kn-affil= affil-num=5 en-affil=Department of Materials Design and Engineering, University of Toyama kn-affil= en-keyword=Water splitting kn-keyword=Water splitting en-keyword=Transition metal dichalcogenide kn-keyword=Transition metal dichalcogenide en-keyword=Hydrogen evolution kn-keyword=Hydrogen evolution en-keyword=Photocatalyst kn-keyword=Photocatalyst en-keyword=Fullerene kn-keyword=Fullerene END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=21 article-no= start-page=11592 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241029 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Epigenetic Regulation of CXC Chemokine Expression by Environmental Electrophiles Through DNA Methyltransferase Inhibition en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ubiquitously distributed environmental electrophiles covalently modify DNA and proteins, potentially leading to adverse health effects. However, the impacts of specific electrophiles on target proteins and their physiological roles remain largely unknown. In the present study, we focused on DNA methylation, which regulates gene expression and physiological responses. A total of 45 environmental electrophiles were screened for inhibitory effects on the activity of DNA methyltransferase 3B (DNMT3B), a key enzyme in DNA methylation, and four compounds were identified. We focused on 1,2-naphthoquinone (1,2-NQ), an air pollutant whose toxicity has been reported previously. Interestingly, we found that 1,2-NQ modified multiple lysine and histidine residues in DNMT3B, one of which was near the active site in DNMT3B. It was found that 1,2-NQ altered gene expression and evoked inflammatory responses in lung adenocarcinoma cell lines. Furthermore, we found that 1,2-NQ upregulated CXCL8 expression through DNA demethylation of the distal enhancer and promoted cancer cell growth. Our study reveals novel mechanisms of epigenetic regulation by environmental electrophiles through the inhibition of DNMT3B activity and suggests their physiological impact. en-copyright= kn-copyright= en-aut-name=TsuchidaTomoki en-aut-sei=Tsuchida en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KubotaSho en-aut-sei=Kubota en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KamiuezonoShizuki en-aut-sei=Kamiuezono en-aut-mei=Shizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakasugiNobumasa en-aut-sei=Takasugi en-aut-mei=Nobumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ItoAkihiro en-aut-sei=Ito en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KumagaiYoshito en-aut-sei=Kumagai en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UeharaTakashi en-aut-sei=Uehara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Medicinal Pharmacology, Faculty of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=School of Life Sciences, Tokyo University of Pharmacy and Life Sciences kn-affil= affil-num=6 en-affil=Graduate School of Pharmaceutical Sciences, Kyushu University kn-affil= affil-num=7 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=DNA methylation kn-keyword=DNA methylation en-keyword=DNA methyltransferase kn-keyword=DNA methyltransferase en-keyword=chemical modification kn-keyword=chemical modification en-keyword=chemokine kn-keyword=chemokine en-keyword=cell proliferation kn-keyword=cell proliferation en-keyword=toxicology kn-keyword=toxicology en-keyword=exposome kn-keyword=exposome en-keyword=environmental electrophiles kn-keyword=environmental electrophiles END start-ver=1.4 cd-journal=joma no-vol=99 cd-vols= no-issue=2 article-no= start-page=563 end-page=574 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241027 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Therapeutic potential of 4-phenylbutyric acid against methylmercury-induced neuronal cell death in mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Methylmercury (MeHg) is an environmental neurotoxin that induces damage to the central nervous system and is the causative agent in Minamata disease. The mechanisms underlying MeHg neurotoxicity remain largely unknown, and there is a need for effective therapeutic agents, such as those that target MeHg-induced endoplasmic reticulum (ER) stress and the unfolded protein response (UPR), which is activated as a defense mechanism. We investigated whether intraperitoneal administration of the chemical chaperone, 4-phenylbutyric acid (4-PBA), at 120 mg/kg/day can alleviate neurotoxicity in the brains of mice administered 50 ppm MeHg in drinking water for 5 weeks. 4-PBA significantly reduced MeHg-induced ER stress, neuronal apoptosis, and neurological symptoms. Furthermore, 4-PBA was effective even when administered 2 weeks after the initiation of exposure to 30 ppm MeHg in drinking water. Our results strongly indicate that ER stress and the UPR are key processes involved in MeHg toxicity, and that 4-PBA is a novel therapeutic candidate for MeHg-induced neurotoxicity. en-copyright= kn-copyright= en-aut-name=MikiRyohei en-aut-sei=Miki en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NomuraRyosuke en-aut-sei=Nomura en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IijimaYuta en-aut-sei=Iijima en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KubotaSho en-aut-sei=Kubota en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakasugiNobumasa en-aut-sei=Takasugi en-aut-mei=Nobumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IwawakiTakao en-aut-sei=Iwawaki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujimuraMasatake en-aut-sei=Fujimura en-aut-mei=Masatake kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UeharaTakashi en-aut-sei=Uehara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Division of Cell Medicine, Department of Life Science, Medical Research Institute, Kanazawa Medical University kn-affil= affil-num=7 en-affil=Department of International Affairs and Research, National Institute for Minamata Disease kn-affil= affil-num=8 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Methylmercury kn-keyword=Methylmercury en-keyword=Neuronal cell death kn-keyword=Neuronal cell death en-keyword=Endoplasmic reticulum stress kn-keyword=Endoplasmic reticulum stress en-keyword=Unfolded protein response kn-keyword=Unfolded protein response END start-ver=1.4 cd-journal=joma no-vol=60 cd-vols= no-issue= article-no= start-page=104813 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Petrological characterization for material provenance of haniwa earthenware from mounded tombs in the Kibi region, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=To determine the provenance of the materials used in the production of haniwa earthenware unearthed from mounded tombs (kofun) in the Kibi region (modern Okayama Prefecture) during the Kofun period (late 3rd ? 6th century CE) of Japan, we carried out petrological analyses of haniwa sherds, including optical microscopy, X-ray diffractometry, X-ray fluorescence spectroscopy, and electron-probe analysis. The 25 haniwa sherds analyzed from 12 representative mounded tombs are composed of mineral and rock inclusions with variable grain size set in a clay matrix. The dominant inclusions are quartz, K-feldspar, and plagioclase, associated with minor amounts of amphibole, volcanic glass, and granitic rocks in all the haniwa sherds, and small amounts of hornfels, quartz rock, and accessory minerals, including mica, ilmenite, and chromite, in some of the sherds. Amphibole and plagioclase have compositional variations indicative of the mixing of tephra and granitic components. The compositions of volcanic glass inclusions are similar to those of the Aira-Tanzawa and Kikai-Akahoya tephras widely distributed in southwestern Japan. Bulk chemical compositions show magmatic differentiation trends, which are variable between individual tombs. From these results, it is concluded that the paste materials of haniwa in the Kibi region were commonly derived from weathered granitic rocks mixed with minor amounts of three widespread tephras. The variations of chemical and mineralogical compositions are probably the reflection of local geologic settings, suggesting the presence of specific mining sites of paste materials around each tomb. The mining sites could be located at the bases of hills of granitic rocks covered by widespread tephras and in some cases, near the flood plain of big river systems. en-copyright= kn-copyright= en-aut-name=NozakaToshio en-aut-sei=Nozaka en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhbayashiNaoya en-aut-sei=Ohbayashi en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TodaYuki en-aut-sei=Toda en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SugiuraKanako en-aut-sei=Sugiura en-aut-mei=Kanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NozakiTakahiro en-aut-sei=Nozaki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KimuraOsamu en-aut-sei=Kimura en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoNaoko en-aut-sei=Matsumoto en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SeikeAkira en-aut-sei=Seike en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Archaeology, Okayama University kn-affil= affil-num=5 en-affil=Research Institute for the Dynamics of Civilizations, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for the Dynamics of Civilizations, Okayama University kn-affil= affil-num=7 en-affil=Research Institute for the Dynamics of Civilizations, Okayama University kn-affil= affil-num=8 en-affil=Department of Archaeology, Okayama University kn-affil= en-keyword=Haniwa kn-keyword=Haniwa en-keyword=Paste material kn-keyword=Paste material en-keyword=Provenance kn-keyword=Provenance en-keyword=Kofun kn-keyword=Kofun en-keyword=Kibi kn-keyword=Kibi en-keyword=Japan kn-keyword=Japan END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=17 article-no= start-page=4368 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240904 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Antibacterial Dental Adhesive Containing Cetylpyridinium Chloride Montmorillonite en-subtitle= kn-subtitle= en-abstract= kn-abstract=Oral bacteria cause tooth caries and periodontal disease. Much research is being conducted to prevent both major oral diseases by rendering dental materials' antimicrobial potential. However, such antimicrobial materials are regarded as 'combination' products and face high hurdles for regulatory approval. We loaded inorganic montmorillonite with the antimicrobial agent cetylpyridinium chloride, referred to below as 'CPC-Mont'. CPC-Mont particles in a 1, 3 and 5 wt% concentration were added to the considered gold-standard self-etch adhesive Clearfil SE Bond 2 ('CSE2'; Kuraray Noritake) to render its antibacterial potential (CSE2 without CPC-Mont served as control). Besides measuring (immediate) bonding effectiveness and (aged) bond durability to dentin, the antibacterial activity against S. mutans and the polymerization-conversion rate was assessed. Immediate and aged bond strength was not affected by 1 and 3 wt% CPC-Mont addition, while 5 wt% CPC-Mont significantly lowered bond strength and bond durability. The higher the concentration of the antimicrobial material added, the stronger the antimicrobial activity. Polymerization conversion was not affected by the CPC-Mont addition in any of the three concentrations. Hence, adding 3 wt% CPC-Mont to the two-step self-etch adhesive rendered additional antimicrobial potential on top of its primary bonding function. en-copyright= kn-copyright= en-aut-name=OkazakiYohei en-aut-sei=Okazaki en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamoriKiichi en-aut-sei=Nakamori en-aut-mei=Kiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YaoChenmin en-aut-sei=Yao en-aut-mei=Chenmin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AhmedMohammed H. en-aut-sei=Ahmed en-aut-mei=Mohammed H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MercelisBenjamin en-aut-sei=Mercelis en-aut-mei=Benjamin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NagaokaNoriyuki en-aut-sei=Nagaoka en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MaruoYukinori en-aut-sei=Maruo en-aut-mei=Yukinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshidaYasuhiro en-aut-sei=Yoshida en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AbeYasuhiko en-aut-sei=Abe en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=Van MeerbeekMeerbeek, Bart en-aut-sei=Van Meerbeek en-aut-mei=Meerbeek, Bart kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YoshiharaKumiko en-aut-sei=Yoshihara en-aut-mei=Kumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Oral Health Sciences, BIOMAT, KU Leuven kn-affil= affil-num=2 en-affil=Department of Advanced Prosthodontics, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=3 en-affil=Department of Oral Health Sciences, BIOMAT, KU Leuven kn-affil= affil-num=4 en-affil=Department of Oral Health Sciences, BIOMAT, KU Leuven kn-affil= affil-num=5 en-affil=Department of Oral Health Sciences, BIOMAT, KU Leuven kn-affil= affil-num=6 en-affil=Advanced Research Center for Oral and Craniofacial Science, Okayama University Dental School kn-affil= affil-num=7 en-affil=Department of Prosthodontics, Okayama University kn-affil= affil-num=8 en-affil=Department of Biomaterials and Bioengineering, Faculty of Dental Medicine, Hokkaido University kn-affil= affil-num=9 en-affil=Department of Advanced Prosthodontics, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=10 en-affil=Department of Oral Health Sciences, BIOMAT, KU Leuven kn-affil= affil-num=11 en-affil=Department of Pathology & Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=dental adhesive kn-keyword=dental adhesive en-keyword=antibacterial agent kn-keyword=antibacterial agent en-keyword=dentin kn-keyword=dentin en-keyword=degree of conversion kn-keyword=degree of conversion en-keyword=micro tensile bond strength kn-keyword=micro tensile bond strength en-keyword=scanning microscopy kn-keyword=scanning microscopy END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=15 article-no= start-page=4384 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240726 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of Serum Indoxyl Sulfate on One-Year Adverse Events in Chronic Kidney Disease Patients with Heart Failure en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Indoxyl sulfate, a uremic toxin, is associated with mortality and cardiovascular events in patients with chronic kidney disease (CKD). This study aimed to evaluate the prognostic implications of serum indoxyl sulfate levels in patients with heart failure and CKD. Methods and Results: This was a prospective multicenter observational study. Overall, 300 patients with chronic heart failure with a previous history of hospitalization and an estimated glomerular filtration rate (eGFR) of 45 mL/min/1.73 m2 or less (CKD stage G3b to G5) without dialysis were analyzed. The primary outcome assessed in a time-to-event analysis from the measurement of indoxyl sulfate was a composite of all-cause death, hospitalization for heart failure, nonfatal myocardial infarction, and nonfatal stroke. Clinical events were followed-up to one year after indoxyl sulfate measurement. The median patient age was 75 years, and 57% of the patients were men. We divided the cohort into low and high indoxyl sulfate categories according to a median value of 9.63 mg/mL. The primary outcome occurred in 27 of 150 patients (18.0%) in the low indoxyl sulfate group and 27 of 150 patients (18.0%) in the high indoxyl sulfate group (hazard ratio, 1.00; 95% confidence interval, 0.58 to 1.70, p = 0.99). In the post hoc exploratory analyses, the results were consistent across age, sex, body mass index, left ventricular ejection fraction, eGFR, and N-terminal pro b-type natriuretic peptide. Conclusions: Among heart failure patients with CKD stages G3b to 5G, serum indoxyl sulfate concentrations were not significantly associated with the subsequent occurrence of cardiovascular events. en-copyright= kn-copyright= en-aut-name=IwasakiKeiichiro en-aut-sei=Iwasaki en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UrabeChikara en-aut-sei=Urabe en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakuragiSatoru en-aut-sei=Sakuragi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawaiYusuke en-aut-sei=Kawai en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FukeSoichiro en-aut-sei=Fuke en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=DoiMasayuki en-aut-sei=Doi en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakaishiAtsushi en-aut-sei=Takaishi en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkaTakefumi en-aut-sei=Oka en-aut-mei=Takefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TokunagaNaoto en-aut-sei=Tokunaga en-aut-mei=Naoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Institute of Academic and Research, Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Institute of Academic and Research, Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Institute of Academic and Research, Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Iwakuni Clinical Center kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama City Hospital kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Japanese Red Cross Okayama Hospital kn-affil= affil-num=7 en-affil=Department of Cardiology, Kagawa Prefectural Central Hospital kn-affil= affil-num=8 en-affil=Department of Cardiology, Mitoyo General Hospital kn-affil= affil-num=9 en-affil=Department of Cardiology, Tsuyama Chuo Hospital kn-affil= affil-num=10 en-affil=Department of Cardiology, Ibara City Hospital kn-affil= affil-num=11 en-affil=Department of General Internal Medicine 3, Kawasaki Medical School kn-affil= en-keyword=heart failure kn-keyword=heart failure en-keyword=chronic kidney disease kn-keyword=chronic kidney disease en-keyword=indoxyl sulfate kn-keyword=indoxyl sulfate END start-ver=1.4 cd-journal=joma no-vol=47 cd-vols= no-issue=6 article-no= start-page=1119 end-page=1122 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Epigenetic Regulation of Carbonic Anhydrase 9 Expression by Nitric Oxide in Human Small Airway Epithelial Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=DNA methylation is a crucial epigenetic modification that regulates gene expression and determines cell fate; however, the triggers that alter DNA methylation levels remain unclear. Recently, we showed that S-nitrosylation of DNA methyltransferase (DNMT) induces DNA hypomethylation and alters gene expression. Furthermore, we identified DBIC, a specific inhibitor of S-nitrosylation of DNMT3B, to suppress nitric oxide (NO)-induced gene alterations. However, it remains unclear how NO-induced DNA hypomethylation regulates gene expression and whether this mechanism is maintained in normal cells and triggers disease-related changes. To address these issues, we focused on carbonic anhydrase 9 (CA9), which is upregulated under nitrosative stress in cancer cells. We pharmacologically evaluated its regulatory mechanisms using human small airway epithelial cells (SAECs) and DBIC. We demonstrated that nitrosative stress promotes the recruitment of hypoxia-inducible factor 1 alpha to the CA9 promoter region and epigenetically induces CA9 expression in SAECs. Our results suggest that nitrosative stress is a key epigenetic regulator that may cause diseases by altering normal cell function. en-copyright= kn-copyright= en-aut-name=MoriyaYuto en-aut-sei=Moriya en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KubotaSho en-aut-sei=Kubota en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IijimaYuta en-aut-sei=Iijima en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakasugiNobumasa en-aut-sei=Takasugi en-aut-mei=Nobumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UeharaTakashi en-aut-sei=Uehara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=nitric oxide kn-keyword=nitric oxide en-keyword=human small airway epithelial cell kn-keyword=human small airway epithelial cell en-keyword=epigenetics kn-keyword=epigenetics en-keyword=DNA methylation kn-keyword=DNA methylation en-keyword=carbonic anhydrase 9 kn-keyword=carbonic anhydrase 9 en-keyword=hypoxia-inducible factor 1 alpha kn-keyword=hypoxia-inducible factor 1 alpha END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=11 article-no= start-page=e31872 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240615 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bacterial DNA and serum IgG antibody titer assays for assessing infection of human-pathogenic and dog-pathogenic Porphyromonas species in dogs en-subtitle= kn-subtitle= en-abstract= kn-abstract=Periodontal disease is highly prevalent in both humans and dogs. Although there have been reports of cross-infection of periodontopathic bacteria, methods for assessing it have yet to be established. The actual status of cross-infection remains to be seen. The purpose of this study was to evaluate the utility of bacterial DNA and serum immunoglobulin G (IgG) antibody titer assays to assess infection of human-pathogenic and dog-pathogenic Porphyromonas species in dogs. Four experimental beagles were used for establishing methods. Sixty-six companion dogs at veterinary clinics visiting for treatment and prophylaxis of periodontal disease were used and divided into healthy, gingivitis, and periodontitis groups. Periodontal pathogens such as Porphyromonas gingivalis and Porphyromonas gulae were investigated as target bacteria. DNA levels of both bacteria were measured using species-specific primers designed for real-time polymerase chain reaction (PCR). Serum IgG titers of both bacteria were measured by enzyme-linked immunosorbent assay (ELISA).
PCR primers were confirmed to have high sensitivity and specificity. However, there was no relationship between the amount of bacterial DNA and the severity of the periodontal disease. In addition, dogs with periodontitis had higher IgG titers against both bacteria compared to dogs in the healthy and gingivitis groups; there was cross-reactivity between the two bacteria. Receiver operating characteristic (ROC) analysis of IgG titers against both bacteria showed high sensitivity (>90 %) and specificity (>75 %). Since both bacteria were distinguished by DNA assays, the combination of these assays may be useful in the evaluation of cross-infection. en-copyright= kn-copyright= en-aut-name=Tai-TokuzenMasako

Empirical observations have led to the misconception that ribosomes are robust protein factories, but in reality, they have several weaknesses. For instance, ribosomes stall during the translation of the proline-rich sequences, but the elongation factor EF-P assists in synthesizing proteins containing the poly-proline sequences. Thus, living organisms have evolved to expand the translation capability of ribosomes through the acquisition of translation elongation factors. In this study, we have revealed that Escherichia coli ATP-Binding Cassette family-F (ABCF) proteins, YheS, YbiT, EttA and Uup, individually cope with various problematic nascent peptide sequences within the exit tunnel. The correspondence between noncanonical translations and ABCFs was YheS for the translational arrest by nascent SecM, YbiT for poly-basic sequence-dependent stalling and poly-acidic sequence-dependent intrinsic ribosome destabilization (IRD), EttA for IRD at the early stage of elongation, and Uup for poly-proline-dependent stalling. Our results suggest that ATP hydrolysis-coupled structural rearrangement and the interdomain linker sequence are pivotal for handling 'hard-to-translate' nascent peptides. Our study highlights a new aspect of ABCF proteins to reduce the potential risks that are encoded within the nascent peptide sequences.

We aimed to compile and update information on the epidemiology of vibriosis in South Asia.
Methods: For this systematic review and meta-analysis, we searched PubMed, Web of Science, EMBASE, and Google Scholar for studies related to vibriosis in South Asia published up to May 2023. A random-effects meta-analysis was used to estimate the pooled isolation rate of non-cholera-causing Vibrio species.
Results: In total, 38 studies were included. Seven of these were case reports and 22 were included in the meta-analysis. The reported vibriosis cases were caused by non-O1/non-O139 V. cholerae, V. parahaemolyticus, V. fluvialis, and V. vulnificus. The overall pooled isolation rate was 4.0% (95% confidence interval [CI] 3.0-5.0%) in patients with diarrhea. Heterogeneity was high (I-2 = 98.0%). The isolation rate of non-O1/non-O139 V. cholerae, V. parahaemolyticus, and V. fluvialis were 9.0 (95% CI 7.0-10.0%), 1.0 (95% CI 1.0-2.0%), and 2.0 (95% CI: 1.0-3.0%), respectively. Regarding V. parahaemolyticus, O3:K6 was the most frequently isolated serotype. Cases peaked during summer. Several studies reported antibiotic-resistant strains and those harboring extended-spectrum beta-lactamases genes.
Conclusions: This study demonstrates a high burden of infections caused by non-cholera-causing Vibrio species in South Asia. en-copyright= kn-copyright= en-aut-name=MuzemboBasilua Andre en-aut-sei=Muzembo en-aut-mei=Basilua Andre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitaharaKei en-aut-sei=Kitahara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhnoAyumu en-aut-sei=Ohno en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KhatiwadaJanuka en-aut-sei=Khatiwada en-aut-mei=Januka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DuttaShanta en-aut-sei=Dutta en-aut-mei=Shanta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyoshiShin-Ichi en-aut-sei=Miyoshi en-aut-mei=Shin-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Social Work Institute kn-affil= affil-num=5 en-affil=Division of Bacteriology, ICMR-National Institute of Cholera and Enteric Diseases kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Vibrio parahaemolyticus kn-keyword=Vibrio parahaemolyticus en-keyword=Vibrio vulnificus kn-keyword=Vibrio vulnificus en-keyword=Vibrio mimicus kn-keyword=Vibrio mimicus en-keyword=Vibrio fluvialis kn-keyword=Vibrio fluvialis en-keyword=Seafood kn-keyword=Seafood en-keyword=Gastroenteritis kn-keyword=Gastroenteritis END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue= article-no= start-page=e17013 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240405 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Heterogeneity of the effect of the COVID-19 pandemic on the incidence of Metabolic Syndrome onset at a Japanese campus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background. The coronavirus disease 2019 (COVID-19) outbreak began in China in December 2019, with the World Health Organization declaring a state of emergency in January 2020. Worldwide implementation of lockdown measures to slow the spread of the virus led to reduced physical activity, disrupted eating habits, mental health issues, and sleep disturbances, which increased the risk of lifestyle -related diseases such as metabolic syndrome (MetS). During the COVID-19 pandemic, healthcare workers, especially intensive care workers, experienced longer working hours and burnout, which further increased the risk of lifestyle -related diseases. Accordingly, it is important to identify individuals at a risk of new -onset MetS during a pandemic, which could direct preventive interventions. This study aimed to assess the heterogeneous impact of the COVID-19 pandemic on the incidence of new -onset MetS based on the conditional average treatment effect (CATE) and to identify at -risk populations.
Methods. This study analyzed health checkup data obtained from Okayama University Shikata Campus workers using paired baseline and follow-up years. Baseline data encompassed 2017 to 2019, with respective follow-up data from 2018 to 2020. Furthermore, as the COVID-19 pandemic in Japan began in January 2020, workers who underwent follow-up health checkups in 2018 to 2019 and 2020 were considered as "unexposed"and "exposed,"respectively. As the Shikata campus has several departments, comparisons among departments were made. The primary outcome was new -onset MetS at follow-up. Predictor variables included baseline health checkup results, sex, age, and department (administrative, research, medical, or intensive care department). X -learner was used to calculate the CATE.
Results. This study included 3,572 eligible individuals (unexposed, n = 2,181; exposed, n = 1,391). Among them, 1,544 (70.8%) and 866 (62.3%) participants in the unexposed and exposed groups, respectively, were females. The mean age (+/- standard deviation) of the unexposed and exposed groups was 48.2 +/- 8.2 and 47.8 +/- 8.3 years, respectively. The COVID-19 pandemic increased the average probability of new -onset MetS by 4.4% in the overall population. According to the department, the intensive care department showed the highest CATE, with a 15.4% increase. Moreover, there was large heterogeneity according to the department. The high-CATE group was characterized by older age, urinary protein, elevated liver enzymes, higher triglyceride levels, and a history of hyperlipidemia treatment.
Conclusions. This study demonstrated that the COVID-19 pandemic increased the incidence of new -onset MetS, with this effect showing heterogeneity at a single Japanese campus. Regarding specific populations, workers in the intensive care department showed an increased risk of new -onset MetS. At -risk populations require specific preventive interventions in case the current COVID-19 pandemic persists or a new pandemic occurs. en-copyright= kn-copyright= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=Metabolic syndrome kn-keyword=Metabolic syndrome en-keyword=Healch check up kn-keyword=Healch check up en-keyword=Conditional average treatment effect kn-keyword=Conditional average treatment effect en-keyword=CATE kn-keyword=CATE en-keyword=Public health kn-keyword=Public health en-keyword=Pandemic kn-keyword=Pandemic END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=37 article-no= start-page=4338 end-page=4343 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=2023 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Catalytic synthesis and physical properties of CO2-based cross-linked poly(cyclohexene carbonate)s en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bifunctional aluminum porphyrins (0.001 mol%) catalyzed the terpolymerization of cyclohexene oxide (CHO), bis(CHO), and CO2 to give cross-linked polycarbonates (CLPs) under solvent-free conditions. A small amount of bis(CHO) acted as a cross-linking agent, and the use of only 0.1 mol% bis(CHO) to CHO produced polymers of quite large sizes. The thermal and mechanical properties of CLPs could be altered by changing the structure and amount of bis(CHO), and the CLPs showed improved thermal stability and tensile strength as compared to linear poly(cyclohexene carbonate)s (PCHCs). The degradation of the CLPs was also investigated, and the selective cleavage of the cross-links was achieved by UV light irradiation to give linear PCHCs. The present study disclosed the potentials of cross-linking terpolymerization for the preparation of various CLPs with a constant CO2 content (31 wt%). en-copyright= kn-copyright= en-aut-name=MaedaChihiro en-aut-sei=Maeda en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawabataKenta en-aut-sei=Kawabata en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NikiKaito en-aut-sei=Niki en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakoYuma en-aut-sei=Sako en-aut-mei=Yuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkiharaTakumi en-aut-sei=Okihara en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=EmaTadashi en-aut-sei=Ema en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=154 cd-vols= no-issue=3 article-no= start-page=209 end-page=217 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Attenuation of protein arginine dimethylation via S-nitrosylation of protein arginine methyltransferase 1 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Upregulation of nitric oxide (NO) production contributes to the pathogenesis of numerous diseases via S-nitro- sylation, a post-translational modification of proteins. This process occurs due to the oxidative reaction between NO and a cysteine thiol group; however, the extent of this reaction remains unknown. S-Nitrosylation of PRMT1, a major asymmetric arginine methyltransferase of histones and numerous RNA metabolic proteins, was induced by NO donor treatment. We found that nitrosative stress leads to S-nitrosylation of cysteine 119, located near the active site, and attenuates the enzymatic activity of PRMT1. Interestingly, RNA sequencing analysis revealed similarities in the changes in expression elicited by NO and PRMT1 inhibitors or knockdown. A comprehensive search for PRMT1 substrates using the proximity-dependent biotin identification method highlighted many known and new substrates, including RNA-metabolizing enzymes. To validate this result, we selected the RNA helicase DDX3 and demonstrated that arginine methylation of DDX3 is induced by PRMT1 and attenuated by NO treatment. Our results suggest the existence of a novel regulatory system associated with transcription and RNA metabolism via protein S-nitrosylation. en-copyright= kn-copyright= en-aut-name=TaniguchiRikako en-aut-sei=Taniguchi en-aut-mei=Rikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoriyaYuto en-aut-sei=Moriya en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DohmaeNaoshi en-aut-sei=Dohmae en-aut-mei=Naoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuzukiTakehiro en-aut-sei=Suzuki en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakaharaKengo en-aut-sei=Nakahara en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KubotaSho en-aut-sei=Kubota en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakasugiNobumasa en-aut-sei=Takasugi en-aut-mei=Nobumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UeharaTakashi en-aut-sei=Uehara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Biomolecular Characterization Unit, Technology Platform Division, RIKEN Center for Sustainable Resource Science kn-affil= affil-num=4 en-affil=Biomolecular Characterization Unit, Technology Platform Division, RIKEN Center for Sustainable Resource Science kn-affil= affil-num=5 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Nitric oxide kn-keyword=Nitric oxide en-keyword=S-Nitrosylation kn-keyword=S-Nitrosylation en-keyword=Protein arginine methyltransferase 1 (PRMT1) kn-keyword=Protein arginine methyltransferase 1 (PRMT1) en-keyword=RNA metabolism kn-keyword=RNA metabolism en-keyword=Dead-box helicase 3X-linxed (DDX3) kn-keyword=Dead-box helicase 3X-linxed (DDX3) END start-ver=1.4 cd-journal=joma no-vol=49 cd-vols= no-issue=2 article-no= start-page=55 end-page=60 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Methylmercury-induced brain neuronal death in CHOP-knockout mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Apoptosis is one of the hallmarks of MeHg-induced neuronal cell death; however, its molecular mechanism remains unclear. We previously reported that MeHg exposure induces neuron-specific ER stress in the mouse brain. Excessive ER stress contributes to apoptosis, and CHOP induction is considered to be one of the major mechanisms. CHOP is also increased by MeHg exposure in the mouse brain, suggesting that it correlates with increased apoptosis. In this study, to clarify whether CHOP mediates MeHg-induced apoptosis, we examined the effect of CHOP deletion on MeHg exposure in CHOP-knockout mice. Our data showed that CHOP deletion had no effect on MeHg exposure-induced weight loss or hindlimb impairment in mice, nor did it increase apoptosis or inhibit neuronal cell loss. Hence, CHOP plays little role in MeHg toxicity, and other apoptotic pathways coupled with ER stress may be involved in MeHg-induced cell death. en-copyright= kn-copyright= en-aut-name=IijimaYuta en-aut-sei=Iijima en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MikiRyohei en-aut-sei=Miki en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujimuraMasatake en-aut-sei=Fujimura en-aut-mei=Masatake kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OyadomariSeiichi en-aut-sei=Oyadomari en-aut-mei=Seiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UeharaTakashi en-aut-sei=Uehara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Basic Medical Science, National Institute for Minamata Disease kn-affil= affil-num=4 en-affil=Division of Molecular Biology, Institute of Advanced Medical Sciences, Tokushima University kn-affil= affil-num=5 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Methylmercury kn-keyword=Methylmercury en-keyword=Neuronal cell death kn-keyword=Neuronal cell death en-keyword=Apoptosis kn-keyword=Apoptosis en-keyword=CHOP kn-keyword=CHOP en-keyword=Knockout mouse kn-keyword=Knockout mouse END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=8 article-no= start-page=707 end-page=713 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Terpolymerizations of cyclohexene oxide, CO2, and isocyanates or isothiocyanates for the synthesis of poly(carbonate?urethane)s or poly(carbonate?thioimidocarbonate)s en-subtitle= kn-subtitle= en-abstract= kn-abstract=Terpolymerization of cyclohexene oxide (CHO), CO2, and aryl isothiocyanates produced poly(carbonate?thioimidocarbonate)s with gradient character, while that of CHO, CO2, and aryl isocyanates furnished poly(carbonate?urethane)s with random sequences.

Steroid hormones are synthesized through the actions of steroidogenic enzymes, specifically STAR, CYP11A1, HSD3B, and CYP19A1 in both theca cells (TCs) and granulosa cells (GCs), under the influence of gonadotropins. Particularly, estradiol 17 beta (E2) assumes a central role in follicular development and selection by activating estrogen receptors beta (ESR2) in GCs. We assessed ESR2 mRNA expression in GCs of developing follicles and investigated the impact of IGF-1 on the mRNA expression of ESR2, CYP19A1, FSHR, and LHCGR, STAR, CYP11A1, and HSD17B in cultured GCs and TCs, respectively. Additionally, we assessed the influence of IGF-1 on androstenedione (A4), progesterone (P4), and testosterone (T) production in TCs. Small-sized follicles (< 6 mm) exhibited the highest levels of ESR2 mRNA expression, whereas medium-sized follicles (7-8 mm) displayed higher levels than large-sized follicles (>= 9 mm) (P < 0.05). IGF-1 increased the mRNA expression of ESR2, CYP19A1, and FSHR in GCs of follicles of both sizes, except for FSHR mRNA in medium-sized follicles (P < 0.05). IGF-1 significantly elevated mRNA expression of LHCGR, STAR, CYP11A1, and CYP17B in TCs of small-and medium-sized follicles (P < 0.05). Moreover, IGF-1 augmented the production of A4 and P4 but had no impact on T production in TCs of small-and medium-sized follicles. Taken together, our findings indicate that IGF-1 upregulates steroidogenic enzymes and steroid hormone production, underscoring the crucial role of IGF-1 in follicle development and selection. en-copyright= kn-copyright= en-aut-name=RawanAhmad Farid en-aut-sei=Rawan en-aut-mei=Ahmad Farid kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LangarHikmatullah en-aut-sei=Langar en-aut-mei=Hikmatullah kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MunetomoMaho en-aut-sei=Munetomo en-aut-mei=Maho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoYuki en-aut-sei=Yamamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawanoKohei en-aut-sei=Kawano en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KimuraKoji en-aut-sei=Kimura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Laboratory of Reproductive Physiology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Reproductive Physiology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Reproductive Physiology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Laboratory of Reproductive Physiology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Laboratory of Reproductive Physiology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Laboratory of Reproductive Physiology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Estradiol receptor kn-keyword=Estradiol receptor en-keyword=Follicle kn-keyword=Follicle en-keyword=Insulin-like growth factor-1 (IGF-1) kn-keyword=Insulin-like growth factor-1 (IGF-1) en-keyword=Steroidogenic enzymes kn-keyword=Steroidogenic enzymes END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=11 article-no= start-page=1661 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231030 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characteristics of Persistent Symptoms Manifested after SARS-CoV-2 Vaccination: An Observational Retrospective Study in a Specialized Clinic for Vaccination-Related Adverse Events en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Although many adverse reactions after SARS-CoV-2 vaccination have been reported, there have been few comprehensive studies on persistent symptoms after SARS-CoV-2 vaccination. The aim of this study was to determine the clinical characteristics of patients with various persistent symptoms after SARS-CoV-2 vaccination. Methods: A retrospective descriptive study was performed for patients who visited a specialized clinic established at Okayama University Hospital to evaluate adverse events after SARS-CoV-2 vaccination during the period from April 2021 to March 2023. Results: Descriptive analysis was performed for 121 of 127 patients who visited the clinic during the study period, and separate analysis was performed for the other 6 patients who had serious complications, who required treatment with prednisolone, and who had persistent symptoms. The median [interquartile range] age of the patients was 48 years [31-64 years], and the patients included 44 males (36.4%) and 77 females (63.6%). The most frequent symptoms were sensory impairment (34 patients, 28.1%), general fatigue (30 patients, 24.8%), fever/low-grade fever (21 patients, 17.4%), and headache (21 patients, 17.4%). Serious complications included myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), sarcoidosis, aseptic meningitis, neuromyelitis optica spectrum disorders (NMOSDs), tendon adhesions, and idiopathic thrombocytopenia. Conclusions: Although causal relationships were not determined, 15 persistent symptoms after SARS-CoV-2 vaccination were characterized. All of the symptoms had onset from 12 hours to one week after vaccination, with 10 symptoms persisting for 6 months or longer. The most frequent symptom was sensory impairment. en-copyright= kn-copyright= en-aut-name=TokumasuKazuki en-aut-sei=Tokumasu en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Fujita-YamashitaManami en-aut-sei=Fujita-Yamashita en-aut-mei=Manami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SunadaNaruhiko en-aut-sei=Sunada en-aut-mei=Naruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakuradaYasue en-aut-sei=Sakurada en-aut-mei=Yasue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoKoichiro en-aut-sei=Yamamoto en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsudaYui en-aut-sei=Matsuda en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=HasegawaToru en-aut-sei=Hasegawa en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=HondaHiroyuki en-aut-sei=Honda en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=adverse events kn-keyword=adverse events en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=SARS-CoV-2 vaccination kn-keyword=SARS-CoV-2 vaccination en-keyword=mRNA vaccine kn-keyword=mRNA vaccine END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=サガリバナ (Barringtonia racemosa) の成分研究を例にした植物の分類体系解析 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=YOSHIKAWAShinji en-aut-sei=YOSHIKAWA en-aut-mei=Shinji kn-aut-name=吉川伸仁 kn-aut-sei=吉川 kn-aut-mei=伸仁 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol=38 cd-vols= no-issue= article-no= start-page=101669 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=2022 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Massive hemoptysis in a post-operative patient with recurrent lung cancer successfully treated by the combination therapy of Endobronchial Watanabe Spigot and bronchial artery embolization en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 76-year-old woman who was treated with lorlatinib for postoperative recurrent anaplastic lymphoma kinase-positive lung adenocarcinoma visited our hospital with massive hemoptysis. Chest computed tomography showed massive bleeding from the right upper lobe; however, the cause of bleeding was unclear. After bronchial artery embolization (BAE), bronchial occlusion was performed using an Endobronchial Watanabe Spigot (EWS) that was easily placed because BAE had reduced the bleeding volume. Treatment with BAE alone was inadequate; however, additional therapy with EWS after BAE successfully controlled the massive hemoptysis, especially in this patient who underwent lobectomy to prevent respiratory dysfunction. en-copyright= kn-copyright= en-aut-name=TaokaMasataka en-aut-sei=Taoka en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MakimotoGo en-aut-sei=Makimoto en-aut-mei=Go kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=NinomiyaKiichiro en-aut-sei=Ninomiya en-aut-mei=Kiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HigoHisao en-aut-sei=Higo en-aut-mei=Hisao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatoYuka en-aut-sei=Kato en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujiiMasanori en-aut-sei=Fujii en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KuboToshio en-aut-sei=Kubo en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IchiharaEiki en-aut-sei=Ichihara en-aut-mei=Eiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=HottaKatsuyuki en-aut-sei=Hotta en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TabataMasahiro en-aut-sei=Tabata en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=KiuraKatsuyuki en-aut-sei=Kiura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=6 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Center for Clinical Oncology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=12 en-affil=Center for Clinical Oncology, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= en-keyword=Hemoptysis kn-keyword=Hemoptysis en-keyword=Bronchial artery embolization kn-keyword=Bronchial artery embolization en-keyword=Endoscopic bronchial occlusion kn-keyword=Endoscopic bronchial occlusion en-keyword=Endobronchial Watanabe Spigot kn-keyword=Endobronchial Watanabe Spigot END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=5 article-no= start-page=553 end-page=559 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Favorable Outcome of Repeated Salvage Surgeries for Rare Metastasis to the Ligamentum Teres Hepatis and the Upper Abdominal Wall in a Stage IV Gastric Cancer Patient en-subtitle= kn-subtitle= en-abstract= kn-abstract=Gastric cancer with peritoneal metastases is typically a devastating diagnosis. Ligamentum teres hepatis (LTH) metastasis is an extremely rare presentation with only four known cases. Herein, we report salvage surgery of successive metastases to the abdominal wall and LTH in a patient originally presenting with advanced gastric cancer with peritoneal metastasis, leading to long-term survival. A 72-year-old man with advanced gastric cancer underwent curative-intent distal gastrectomy with D2 lymph node dissection for gastric outlet obstruction. During this procedure, three small peritoneal metastases were detected in the lesser omentum, the small mesentery, and the mesocolon; however, intraoperative abdominal lavage cytology was negative. We added cytoreductive surgery for peritoneal metastasis. The pathological diagnosis of the gastric cancer was tubular adenocarcinoma with pT4aN1pM1(PER/P1b)CY0 stage IV (Japanese classification of gastric carcinoma/JCGC 15th), or T4N1M1b stage IV (UICC 7th). Post-operative adjuvant chemotherapy with S-1 (TS-1)+cisplatin (CDDP) was administered for 8 months followed by S-1 monotherapy for 4 months. At 28 months after the initial surgery, a follow-up computed tomography (CT) detected a small mass beneath the upper abdominal wall. The ass showed mild avidity on 18F-fluorodeoxyglucose positron-emission (FDG-PET) CT. Salvage resection was performed for diagnosis and treatment, and pathological findings were consistent with primary gastric cancer metastasis. At 49 months after the initial gastrectomy, a new lesion was detected in the LTH with a similar level of avidity on FDG-PET CT as the abdominal wall metastatic lesion. We performed a second salvage surgery for the LTH tumor, which also showed pathology of gastric cancer metastasis. There has been no recurrence up to 1 year after the LTH surgery. With multidisciplinary treatment the patient has survived almost 5 years after the initial gastrectomy. Curative-intent gastrectomy with cytoreductive surgery followed by adjuvant chemotherapy for advanced gastric cancer with localized peritoneal metastasis might have had a survival benefit in our patient. Successive salvage surgeries for oligometastatic lesions in the abdominal wall and the LTH also yielded favorable outcomes. en-copyright= kn-copyright= en-aut-name=MurokawaTakahiro en-aut-sei=Murokawa en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakamotoShinya en-aut-sei=Sakamoto en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TabuchiMotoyasu en-aut-sei=Tabuchi en-aut-mei=Motoyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuiKenta en-aut-sei=Sui en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OzakiKazuhide en-aut-sei=Ozaki en-aut-mei=Kazuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsumotoManabu en-aut-sei=Matsumoto en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IwataJun en-aut-sei=Iwata en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkabayashiTakehiro en-aut-sei=Okabayashi en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YoshidaHiroshi en-aut-sei=Yoshida en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=6 en-affil=Department of Diagnostic Pathology, Kochi Health Sciences Center kn-affil= affil-num=7 en-affil=Department of Diagnostic Pathology, Kochi Health Sciences Center kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=9 en-affil=Department of Gastrointestinal and Hepato-Biliary-Pancreatic Surgery, Nippon Medical School kn-affil= en-keyword=gastric cancer kn-keyword=gastric cancer en-keyword=peritoneal metastasis kn-keyword=peritoneal metastasis en-keyword=ligamentum teres hepatis kn-keyword=ligamentum teres hepatis en-keyword=oligometastasis kn-keyword=oligometastasis en-keyword=salvage surgery kn-keyword=salvage surgery END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=7 article-no= start-page=1190 end-page=1202 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220421 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reduction in the magnitude of serum potassium elevation in combination therapy with esaxerenone (CS‐3150) and sodium?glucose cotransporter?2 inhibitor in patients with diabetic kidney disease: Subanalysis of two phase?III studies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims/Introduction: We evaluated the effect of co-administration of esaxerenone and a sodium?glucose cotransporter?2 (SGLT2) inhibitor on the magnitude of serum potassium elevation in Japanese patients with diabetic kidney disease.
Materials and Methods: We carried out a prespecified subanalysis of data from two phase?III studies: a multicenter, randomized, double-blind, placebo-controlled trial in patients with type?2 diabetes and microalbuminuria (J308); and a multicenter, single-arm, open-label trial in patients with type?2 diabetes and macroalbuminuria (J309). Changes in serum potassium levels during the studies and other measures were evaluated according to SGLT2 inhibitor use.
Results: In both studies, time-course changes in serum potassium levels, and incidence rates of serum potassium elevation were lower in patients with co-administration of SGLT2 inhibitor in both the placebo and esaxerenone groups than those without the inhibitor. In contrast, time-course changes and mean percentage changes from baseline in urinary albumin-to-creatinine ratio, the proportion of patients with albuminuria remission and time-course changes in blood pressure did not change with or without SGLT2 inhibitor, whereas the albumin-to-creatinine ratio and blood pressure were reduced with esaxerenone. The blood glucose-lowering effect of SGLT2 inhibitor was not affected by esaxerenone.
Conclusions: In Japanese patients with type?2 diabetes and albuminuria treated with esaxerenone, concomitant use of SGLT2 inhibitor reduced the magnitude of serum potassium elevation without any change of its antihypertensive and albuminuria-suppressing effects. Co-administration of esaxerenone and SGLT2 inhibitor might be a beneficial treatment option for patients with diabetic kidney disease. en-copyright= kn-copyright= en-aut-name=ShikataKenichi en-aut-sei=Shikata en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ItoSadayoshi en-aut-sei=Ito en-aut-mei=Sadayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KashiharaNaoki en-aut-sei=Kashihara en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NangakuMasaomi en-aut-sei=Nangaku en-aut-mei=Masaomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WadaTakashi en-aut-sei=Wada en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkudaYasuyuki en-aut-sei=Okuda en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SawanoboriTomoko en-aut-sei=Sawanobori en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugimotoKotaro en-aut-sei=Sugimoto en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Division of Nephrology, Endocrinology and Vascular Medicine, Department of Medicine, Tohoku University School of Medicine kn-affil= affil-num=3 en-affil=Department of Nephrology and Hypertension, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Division of Nephrology and Endocrinology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=5 en-affil=Department of Nephrology and Laboratory Medicine, Kanazawa University kn-affil= affil-num=6 en-affil=Department of Nephrology and Laboratory Medicine, Kanazawa University kn-affil= affil-num=7 en-affil=Clinical Development Department, Daiichi Sankyo Co., Ltd. kn-affil= affil-num=8 en-affil=Primary Medical Science Department, Daiichi Sankyo Co., Ltd. kn-affil= en-keyword=Esaxerenone kn-keyword=Esaxerenone en-keyword=Potassium kn-keyword=Potassium en-keyword=Sodium-glucose transporter 2 inhibitor kn-keyword=Sodium-glucose transporter 2 inhibitor END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=16 article-no= start-page=5174 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230809 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Switching to Dupilumab from Other Biologics without a Treatment Interval in Patients with Severe Asthma: A Multi-Center Retrospective Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Dupilumab is a fully humanized monoclonal antibody that blocks interleukin4 and interleukin-13 signals. Several large clinical trials have demonstrated the efficacy of dupilumab in patients with severe asthma. However, few studies have examined a switch to dupilumab from other biologics. Methods: This retrospective, multi-center observational study was conducted by the Okayama Respiratory Disease Study Group. Consecutive patients with severe asthma who were switched to dupilumab from other biologics without a treatment interval between May 2019 and September 2021 were enrolled. Patients with a treatment interval of more than twice the standard dosing interval for the previous biologic prior to dupilumab administration were excluded. Results: The median patient age of the 27 patients enrolled in this study was 57 years (IQR, 45-68 years). Eosinophilic chronic rhinosinusitis (ECRS)/chronic rhinosinusitis with nasal polyp (CRSwNP) was confirmed in 23 patients. Previous biologics consisted of omalizumab (n = 3), mepolizumab (n = 3), and benralizumab (n = 21). Dupilumab significantly improved FEV1 (median improvement: +145 mL) and the asthma control test score (median improvement: +2). The overall response rate in patients receiving dupilumab for asthma as determined using the Global Evaluations of Treatment Effectiveness (GETE) was 77.8%. There were no significant differences in the baseline characteristics of the GETE-improved group vs. the non-GETE-improved group. ECRS/CRSwNP improved in 20 of the 23 patients (87.0%). Overall, 8 of the 27 patients (29.6%) developed transient hypereosinophilia (>1500/ mu L), but all were asymptomatic and able to continue dupilumab therapy. Conclusions: Dupilumab was highly effective for the treatment of severe asthma and ECRS/CRSwNP, even in patients switched from other biologics without a treatment interval. en-copyright= kn-copyright= en-aut-name=HigoHisao en-aut-sei=Higo en-aut-mei=Hisao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchikawaHirohisa en-aut-sei=Ichikawa en-aut-mei=Hirohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ArakawaYukako en-aut-sei=Arakawa en-aut-mei=Yukako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriYoshihiro en-aut-sei=Mori en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ItanoJunko en-aut-sei=Itano en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TaniguchiAkihiko en-aut-sei=Taniguchi en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SenooSatoru en-aut-sei=Senoo en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KimuraGoro en-aut-sei=Kimura en-aut-mei=Goro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanimotoYasushi en-aut-sei=Tanimoto en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MiyakeKohei en-aut-sei=Miyake en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KatsutaTomoya en-aut-sei=Katsuta en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KataokaMikio en-aut-sei=Kataoka en-aut-mei=Mikio 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=KiuraKatsuyuki en-aut-sei=Kiura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=MiyaharaNobuaki en-aut-sei=Miyahara en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=Okayama Respiratory Disease Study Group (ORDSG) en-aut-sei=Okayama Respiratory Disease Study Group (ORDSG) en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Respiratory Medicine, KKR Takamatsu Hospital kn-affil= affil-num=3 en-affil=Department of Respiratory Medicine, KKR Takamatsu Hospital kn-affil= affil-num=4 en-affil=Department of Respiratory Medicine, KKR Takamatsu Hospital kn-affil= affil-num=5 en-affil=Department of Allergy and Respiratory Medicine, National Hospital Organization Minami-Okayama Medical Center kn-affil= affil-num=6 en-affil=Department of Hematology, Oncology, and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Hematology, Oncology, and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Allergy and Respiratory Medicine, National Hospital Organization Minami-Okayama Medical Center kn-affil= affil-num=9 en-affil=Department of Allergy and Respiratory Medicine, National Hospital Organization Minami-Okayama Medical Center kn-affil= affil-num=10 en-affil=Department of Respiratory Medicine, National Hospital Organization Himeji Medical Center kn-affil= affil-num=11 en-affil=Department of Respiratory Medicine, Ehime Prefectural Central Hospital kn-affil= affil-num=12 en-affil=Department of Respiratory Medicine, Onomichi Municipal Hospital kn-affil= affil-num=13 en-affil=Department of Hematology, Oncology, and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=15 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=16 en-affil= kn-affil= en-keyword=dupilumab kn-keyword=dupilumab en-keyword=severe asthma kn-keyword=severe asthma en-keyword=treatment interval kn-keyword=treatment interval en-keyword=eosinophilic chronic rhinosinusitis kn-keyword=eosinophilic chronic rhinosinusitis END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=4 article-no= start-page=254 end-page=261 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=2022 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of bovine uterine gland functions in 2D and 3D culture system en-subtitle= kn-subtitle= en-abstract= kn-abstract=In ruminants, uterine glands play key roles in the establishment of pregnancy by secreting various factors into the uterine lumen. Although a three-dimensional (3D) culture system has been used for investigating cellular functions in vitro, the detailed functions of uterine gland have not been fully elucidated. In this study, we examined the benefits of 3D culture system to examine the innate functions of bovine uterine glands. Isolated bovine uterine glands were cultured on Matrigel (2D) or in Matrigel (3D), respectively, and the mRNA levels of secreted proteins (SERPINA14, MEP1B, APOA1, ARSA, CTGF, and SPP1) were measured in isolated and cultured uterine glands. The protein expression of estrogen receptor β (ERβ) and progesterone receptor (PR) and the establishment of apico-basal polarity were examined. In isolated uterine glands, the mRNA levels of secreted proteins changed during the estrous cycle. Although uterine glands cultured in both 2D and 3D expressed ERβ and PR, progesterone did not affect SERPINA14 mRNA expression. The expression of APOA1 mRNA in 2D cultured uterine glands did not respond to estrogen and progesterone. Additionally, the mRNA levels of secreted proteins in the 3D culture system were significantly higher than those in the 2D culture system, which might be attributed to the different cellular morphology between them. The locations of ZO-1 and β-catenin in 2D cultured uterine glands were disordered compared with 3D cultured uterine glands. These results showed that the hormonal responsiveness of secreted factor expression and cellular morphology were different between 2D and 3D cultured bovine uterine glands. en-copyright= kn-copyright= en-aut-name=SUGINOYosuke en-aut-sei=SUGINO en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SATOTaiki en-aut-sei=SATO en-aut-mei=Taiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YAMAMOTOYuki en-aut-sei=YAMAMOTO en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KIMURAKoji en-aut-sei=KIMURA en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Reproductive Physiology, Faculty of Agriculture, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Bovine kn-keyword=Bovine en-keyword=Secreted proteins kn-keyword=Secreted proteins en-keyword=Three-dimensional culture kn-keyword=Three-dimensional culture en-keyword=Uterine glands kn-keyword=Uterine glands 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=15 cd-vols= no-issue=14 article-no= start-page=3665 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230718 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Image-Guided Ablation Therapies for Extrahepatic Metastases from Hepatocellular Carcinoma: A Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Simple Summary Although systemic therapies are a common treatment for patients with extrahepatic metastases from hepatocellular carcinoma (HCC), local ablative therapies, such as radiofrequency ablation, microwave ablation, and cryoablation, can be used in select patients who have metastases to the lung, bone, and other sites with curative or palliative intent. This review summarizes the currently available evidence on image-guided thermal ablation therapies for extrahepatic metastases from HCC. The most common sites of extrahepatic metastases from hepatocellular carcinoma (HCC) are the lungs, intra-abdominal lymph nodes, bones, and adrenal glands, in that order. Although systemic therapies are a common treatment for patients with extrahepatic metastases, local ablative therapies for the extrahepatic metastatic lesions can be performed in selected patients. In this article, the literature on image-guided thermal ablation for metastasis to each organ was reviewed to summarize the current evidence. Radiofrequency ablation was the most commonly evaluated technique, and microwave ablation, cryoablation, and percutaneous ethanol injection were also utilized. The local control rate of thermal ablation therapy was relatively favorable, at approximately 70-90% in various organs. The survival outcomes varied among the studies, and several studies reported that the absence of viable intrahepatic lesions was associated with improved survival rates. Since only retrospective data from relatively small studies has been available thus far, more robust studies with prospective designs and larger cohorts are desired to prove the usefulness of thermal ablation for extrahepatic metastases from HCC. en-copyright= kn-copyright= en-aut-name=UmakoshiNoriyuki en-aut-sei=Umakoshi en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TomitaKoji en-aut-sei=Tomita en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UkaMayu en-aut-sei=Uka en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawabataTakahiro en-aut-sei=Kawabata en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Science kn-affil= affil-num=7 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=hepatocellular carcinoma kn-keyword=hepatocellular carcinoma en-keyword=extrahepatic metastases kn-keyword=extrahepatic metastases en-keyword=ablation therapy kn-keyword=ablation therapy en-keyword=radiofrequency ablation kn-keyword=radiofrequency ablation en-keyword=microwave ablation kn-keyword=microwave ablation en-keyword=cryoablation kn-keyword=cryoablation en-keyword=percutaneous ethanol injection kn-keyword=percutaneous ethanol injection END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=621 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230204 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pivotal role for S-nitrosylation of DNA methyltransferase 3B in epigenetic regulation of tumorigenesis en-subtitle= kn-subtitle= en-abstract= kn-abstract=DNA methyltransferases (DNMTs) catalyze methylation at the C5 position of cytosine with S-adenosyl-l-methionine. Methylation regulates gene expression, serving a variety of physiological and pathophysiological roles. The chemical mechanisms regulating DNMT enzymatic activity, however, are not fully elucidated. Here, we show that protein S-nitrosylation of a cysteine residue in DNMT3B attenuates DNMT3B enzymatic activity and consequent aberrant upregulation of gene expression. These genes include Cyclin D2 (Ccnd2), which is required for neoplastic cell proliferation in some tumor types. In cell-based and in vivo cancer models, only DNMT3B enzymatic activity, and not DNMT1 or DNMT3A, affects Ccnd2 expression. Using structure-based virtual screening, we discovered chemical compounds that specifically inhibit S-nitrosylation without directly affecting DNMT3B enzymatic activity. The lead compound, designated DBIC, inhibits S-nitrosylation of DNMT3B at low concentrations (IC50 <= 100nM). Treatment with DBIC prevents nitric oxide (NO)-induced conversion of human colonic adenoma to adenocarcinoma in vitro. Additionally, in vivo treatment with DBIC strongly attenuates tumor development in a mouse model of carcinogenesis triggered by inflammation-induced generation of NO. Our results demonstrate that de novo DNA methylation mediated by DNMT3B is regulated by NO, and DBIC protects against tumor formation by preventing aberrant S-nitrosylation of DNMT3B. en-copyright= kn-copyright= en-aut-name=OkudaKosaku en-aut-sei=Okuda en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakaharaKengo en-aut-sei=Nakahara en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ItoAkihiro en-aut-sei=Ito en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IijimaYuta en-aut-sei=Iijima en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NomuraRyosuke en-aut-sei=Nomura en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KumarAshutosh en-aut-sei=Kumar en-aut-mei=Ashutosh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujikawaKana en-aut-sei=Fujikawa en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AdachiKazuya en-aut-sei=Adachi en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShimadaYuki en-aut-sei=Shimada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujioSatoshi en-aut-sei=Fujio en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YamamotoReina en-aut-sei=Yamamoto en-aut-mei=Reina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TakasugiNobumasa en-aut-sei=Takasugi en-aut-mei=Nobumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OnumaKunishige en-aut-sei=Onuma en-aut-mei=Kunishige kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=OsakiMitsuhiko en-aut-sei=Osaki en-aut-mei=Mitsuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=OkadaFutoshi en-aut-sei=Okada en-aut-mei=Futoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=UkegawaTaichi en-aut-sei=Ukegawa en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=TakeuchiYasuo en-aut-sei=Takeuchi en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=YasuiNorihisa en-aut-sei=Yasui en-aut-mei=Norihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= en-aut-name=YamashitaAtsuko en-aut-sei=Yamashita en-aut-mei=Atsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=19 ORCID= en-aut-name=MarusawaHiroyuki en-aut-sei=Marusawa en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=20 ORCID= en-aut-name=MatsushitaYosuke en-aut-sei=Matsushita en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=21 ORCID= en-aut-name=KatagiriToyomasa en-aut-sei=Katagiri en-aut-mei=Toyomasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=22 ORCID= en-aut-name=ShibataTakahiro en-aut-sei=Shibata en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=23 ORCID= en-aut-name=UchidaKoji en-aut-sei=Uchida en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=24 ORCID= en-aut-name=NiuSheng-Yong en-aut-sei=Niu en-aut-mei=Sheng-Yong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=25 ORCID= en-aut-name=LangNhi B. en-aut-sei=Lang en-aut-mei=Nhi B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=26 ORCID= en-aut-name=NakamuraTomohiro en-aut-sei=Nakamura en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=27 ORCID= en-aut-name=ZhangKam Y.

kn-abstract=The Y chromosome carries information about the demography of paternal lineages, and thus, can prove invaluable for retracing both the evolutionary trajectory of wild animals and the breeding history of domesticates. In horses, the Y chromosome shows a limited, but highly informative, sequence diversity, supporting the increasing breeding influence of Oriental lineages during the last 1500 years. Here, we augment the primary horse Y-phylogeny, which is currently mainly based on modern horse breeds of economic interest, with haplotypes (HT) segregating in remote horse populations around the world. We analyze target enriched sequencing data of 5 Mb of the Y chromosome from 76 domestic males, together with 89 whole genome sequenced domestic males and five Przewalski's horses from previous studies. The resulting phylogeny comprises 153 HTs defined by 2966 variants and offers unprecedented resolution into the history of horse paternal lineages. It reveals the presence of a remarkable number of previously unknown haplogroups in Mongolian horses and insular populations. Phylogenetic placement of HTs retrieved from 163 archaeological specimens further indicates that most of the present-day Y-chromosomal variation evolved after the domestication process that started around 4200 years ago in the Western Eurasian steppes. Our comprehensive phylogeny significantly reduces ascertainment bias and constitutes a robust evolutionary framework for analyzing horse population dynamics and diversity. en-copyright= kn-copyright=

Taking an excitonic insulator model of electronic ferroelectricity as a prototypical example, we theoretically investigate the low-energy dynamics and transport of electric polarization by microscopically constructing the Ginzburg-Landau action. We show that, because of the scalar nature of the excitonic order parameter, only the longitudinal fluctuations are relevant to the transport of electric polarization. We also formulate the electric-polarization diffusion equation, in which the electric-polarization current is defined purely electronically without recourse to the lattice degrees of freedom. en-copyright= kn-copyright= en-aut-name=AdachiHiroto en-aut-sei=Adachi en-aut-mei=Hiroto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkedaNaoshi en-aut-sei=Ikeda en-aut-mei=Naoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SaitohEiji en-aut-sei=Saitoh en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Physics, Okayama University kn-affil= affil-num=3 en-affil=Department of Applied Physics, The University of Tokyo kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=カーボンナノチューブ/デンドリマーハイブリッドによる水からの水素生成と生体イメージングのための光化学特性 kn-title=Photochemical properties of carbon nanotube/dendrimer hybrids for photocatalytic H2 evolution from water and biomedical imaging en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=YAMAGAMIMasahiro en-aut-sei=YAMAGAMI en-aut-mei=Masahiro kn-aut-name=山~将大 kn-aut-sei=山~ kn-aut-mei=将大 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=実践的なセキュリティオペレーションの高度化と効率化に関する研究 kn-title=Research on Sophistication and Improving Efficiency of Practical Security Operations en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=FUJIIShota en-aut-sei=FUJII en-aut-mei=Shota kn-aut-name=藤井翔太 kn-aut-sei=藤井 kn-aut-mei=翔太 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama university kn-affil=岡山大学大学院自然科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=メチル水銀による小胞体ストレス応答を介した神経細胞死誘導機構 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=NOMURARyosuke en-aut-sei=NOMURA en-aut-mei=Ryosuke kn-aut-name=野村亮輔 kn-aut-sei=野村 kn-aut-mei=亮輔 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=低転移性サブクローン由来のエキソソームwnt7aは、murine 4t1乳がんの高度転移性サブクローンの肺転移を促進する kn-title=Exosomal Wnt7a from a low metastatic subclone promotes lung metastasis of a highly metastatic subclone in the murine 4t1 breast cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=LICHUNNING en-aut-sei=LI en-aut-mei=CHUNNING kn-aut-name=李春寧 kn-aut-sei=李 kn-aut-mei=春寧 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=鶏胚網膜色素上皮の分化に塩基性ヘリックス-ループ-ヘリックス遺伝子BHLHE40が関与する kn-title=Involvement of a Basic Helix-Loop-Helix Gene BHLHE40 in Specification of Chicken Retinal Pigment Epithelium en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KINUHATAToshiki en-aut-sei=KINUHATA en-aut-mei=Toshiki kn-aut-name=衣畑俊希 kn-aut-sei=衣畑 kn-aut-mei=俊希 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=4 article-no= start-page=894 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230406 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Multifunctional Metallothioneins as a Target for Neuroprotection in Parkinson's Disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Parkinson's disease (PD) is characterized by motor symptoms based on a loss of nigrostriatal dopaminergic neurons and by non-motor symptoms which precede motor symptoms. Neurodegeneration accompanied by an accumulation of alpha-synuclein is thought to propagate from the enteric nervous system to the central nervous system. The pathogenesis in sporadic PD remains unknown. However, many reports indicate various etiological factors, such as oxidative stress, inflammation, alpha-synuclein toxicity and mitochondrial impairment, drive neurodegeneration. Exposure to heavy metals contributes to these etiopathogenesis and increases the risk of developing PD. Metallothioneins (MTs) are cysteine-rich metal-binding proteins; MTs chelate metals and inhibit metal-induced oxidative stress, inflammation and mitochondrial dysfunction. In addition, MTs possess antioxidative properties by scavenging free radicals and exert anti-inflammatory effects by suppression of microglial activation. Furthermore, MTs recently received attention as a potential target for attenuating metal-induced alpha-synuclein aggregation. In this article, we summarize MTs expression in the central and enteric nervous system, and review protective functions of MTs against etiopathogenesis in PD. We also discuss neuroprotective strategies for the prevention of central dopaminergic and enteric neurodegeneration by targeting MTs. This review highlights multifunctional MTs as a target for the development of disease-modifying drugs for PD. en-copyright= kn-copyright= en-aut-name=MiyazakiIkuko en-aut-sei=Miyazaki en-aut-mei=Ikuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AsanumaMasato en-aut-sei=Asanuma en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=metallothionein kn-keyword=metallothionein en-keyword=Parkinson's disease kn-keyword=Parkinson's disease en-keyword=neuroprotection kn-keyword=neuroprotection en-keyword=antioxidant kn-keyword=antioxidant en-keyword=metal kn-keyword=metal en-keyword=synuclein kn-keyword=synuclein en-keyword=astrocyte kn-keyword=astrocyte en-keyword=enteric glial cell kn-keyword=enteric glial cell END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=3 article-no= start-page=724 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230124 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Therapeutic Strategies to Overcome Fibrotic Barriers to Nanomedicine in the Pancreatic Tumor Microenvironment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Simple Summary Pancreatic cancer is difficult to treat. Novel treatment strategies are urgently needed to improve the survival rate, which is approximately 10% five years after diagnosis. The use of nanomedicines, which are formulated within a characteristic size range that favors its specific delivery to the diseased tissue, is being actively explored in cancer treatment. However, fibrosis (the abnormal accumulation of a cell type called fibroblasts and the fibrous protein network that they create) is characteristically seen in pancreatic cancer and hinders the delivery of nanomedicines into cancerous tissue. The decreased efficiency of delivery limits the therapeutic effects of nanomedicine in pancreatic cancer. We call this the "fibrotic barrier" to nanomedicine. To overcome the fibrotic barrier, we could target the fibrotic process and/or optimize the nanomedicine design. In this review, we give a detailed overview of strategies to overcome the fibrotic barriers in pancreatic cancer and highlight key gaps in our understanding. Pancreatic cancer is notorious for its dismal prognosis. The enhanced permeability and retention (EPR) effect theory posits that nanomedicines (therapeutics in the size range of approximately 10-200 nm) selectively accumulate in tumors. Nanomedicine has thus been suggested to be the "magic bullet"-both effective and safe-to treat pancreatic cancer. However, the densely fibrotic tumor microenvironment of pancreatic cancer impedes nanomedicine delivery. The EPR effect is thus insufficient to achieve a significant therapeutic effect. Intratumoral fibrosis is chiefly driven by aberrantly activated fibroblasts and the extracellular matrix (ECM) components secreted. Fibroblast and ECM abnormalities offer various potential targets for therapeutic intervention. In this review, we detail the diverse strategies being tested to overcome the fibrotic barriers to nanomedicine in pancreatic cancer. Strategies that target the fibrotic tissue/process are discussed first, which are followed by strategies to optimize nanomedicine design. We provide an overview of how a deeper understanding, increasingly at single-cell resolution, of fibroblast biology is revealing the complex role of the fibrotic stroma in pancreatic cancer pathogenesis and consider the therapeutic implications. Finally, we discuss critical gaps in our understanding and how we might better formulate strategies to successfully overcome the fibrotic barriers in pancreatic cancer. en-copyright= kn-copyright= en-aut-name=TanakaHiroyoshi Y. en-aut-sei=Tanaka en-aut-mei=Hiroyoshi Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakazawaTakuya en-aut-sei=Nakazawa en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EnomotoAtsushi en-aut-sei=Enomoto en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MasamuneAtsushi en-aut-sei=Masamune en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KanoMitsunobu R. en-aut-sei=Kano en-aut-mei=Mitsunobu R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Pharmaceutical Biomedicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pharmaceutical Biomedicine, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology, Graduate School of Medicine, Nagoya University kn-affil= affil-num=4 en-affil=Division of Gastroenterology, Graduate School of Medicine, Tohoku University kn-affil= affil-num=5 en-affil=Department of Pharmaceutical Biomedicine, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=pancreatic cancer kn-keyword=pancreatic cancer en-keyword=tumor microenvironment kn-keyword=tumor microenvironment en-keyword=nanomedicine kn-keyword=nanomedicine en-keyword=fibrosis kn-keyword=fibrosis en-keyword=extracellular matrix kn-keyword=extracellular matrix en-keyword=fibroblast kn-keyword=fibroblast END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=3 article-no= start-page=1921 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202302 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Microcalcification and Tc-99m-Pyrophosphate Uptake without Increased Bone Metabolism in Cardiac Tissue from Patients with Transthyretin Cardiac Amyloidosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Transthyretin cardiac amyloidosis (ATTR-CA) is characterized by high Tc-99m-labeled bone tracer uptake in the heart. However, the mechanism of bone tracer uptake into the heart remains controversial. Since bone tracer uptake into metastatic bone tumors is thought to be associated with increased bone metabolism, we examined Tc-99m-pyrophosphate (PYP) scintigraphy findings, endomyocardial biopsy (EMB) tissue findings, and the expression of bone metabolism-related genes in the EMB tissues in patients with ATTR-CA, amyloid light-chain cardiac amyloidosis (AL-CA), and noncardiac amyloidosis (non-CA) in this study. The uptake of Tc-99m-PYP in the heart was significantly higher in the ATTR-CA patients than in the AL-CA and non-CA patients. A higher percentage of ATTR-CA EMB tissue showed von Kossa-positive microparticles: ATTR-CA, 62%; AL-CA, 33%; and non-CA, 0%. Calcified microparticles were identified using transmission electron microscopy. However, none of the osteogenic marker genes, osteoclastic marker genes, or phosphate/pyrophosphate-related genes were upregulated in the EMB samples from ATTR-CA patients compared to those from AL-CA and non-CA patients. These results suggest that active calcification-promoting mechanisms are not involved in the microcalcification observed in the heart in ATTR-CA. The mechanisms explaining bone tracer uptake in the heart, which is stronger than that in the ribs, require further investigation. en-copyright= kn-copyright= en-aut-name=MoriAtsushi en-aut-sei=Mori en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoYukihiro en-aut-sei=Saito en-aut-mei=Yukihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IidaToshihiro en-aut-sei=Iida en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AkagiSatoshi en-aut-sei=Akagi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshidaMasashi en-aut-sei=Yoshida en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TaniyamaMakiko en-aut-sei=Taniyama en-aut-mei=Makiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Chronic Kidney Disease and Cardiovascular Disease, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of General Medicine, Tamano Division, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=ATTR kn-keyword=ATTR en-keyword=Tc-99m-labeled bone scintigraphy kn-keyword=Tc-99m-labeled bone scintigraphy en-keyword=calcified microparticle kn-keyword=calcified microparticle END start-ver=1.4 cd-journal=joma no-vol=112 cd-vols= no-issue= article-no= start-page=23 end-page=36 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The List of Published by Members of the Faculty From January to December 2022 kn-title=公表学術論文等リスト 2022 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=53 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reliability of the Garden Alignment Index and Valgus Tilt Measurement for Nondisplaced Femoral Neck Fractures en-subtitle= kn-subtitle= en-abstract= kn-abstract=Anteroposterior (AP) alignment assessment for nondisplaced femoral neck fractures is important for determining the treatment strategy and predicting postoperative outcomes. AP alignment is generally measured using the Garden alignment index (GAI). However, its reliability remains unknown. We compared the reliability of GAI and a new AP alignment measurement (valgus tilt measurement [VTM]) using preoperative AP radiographs of nondisplaced femoral neck fractures. The study was designed as an intra- and inter-rater reliability analysis. The raters were four trauma surgeons who assessed 50 images twice. The main outcome was the intraclass correlation coefficient (ICC). To calculate intra- and inter-rater reliability, we used a mixed-effects model considering rater, patient, and time. The overall ICC (95% CI) of GAI and VTM for intra-rater reliability was 0.92 (0.89-0.94) and 0.86 (0.82-0.89), respectively. The overall ICC of GAI and VTM for inter-rater reliability was 0.92 (0.89-0.95), and 0.85 (0.81-0.88), respectively. The intra- and inter-rater reliability of GAI was higher in patients aged <80 years than in patients aged >= 80 years. Our results showed that GAI is a more reliable measurement method than VTM, although both are reliable. Variations in patient age should be considered in GAI measurements. en-copyright= kn-copyright= en-aut-name=YamakawaYasuaki en-aut-sei=Yamakawa en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoNorio en-aut-sei=Yamamoto en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TomitaYosuke en-aut-sei=Tomita en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkudaRyuichiro en-aut-sei=Okuda en-aut-mei=Ryuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasadaYasutaka en-aut-sei=Masada en-aut-mei=Yasutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShiroshitaAkihiro en-aut-sei=Shiroshita en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoToshiyuki en-aut-sei=Matsumoto en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Kochi Health Sciences Center kn-affil= affil-num=2 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Physical Therapy, Faculty of Health Care, Takasaki University of Health and Welfare kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Kochi Health Sciences Center kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Kochi Health Sciences Center kn-affil= affil-num=6 en-affil=Scientific Research Works Peer Support Group (SRWS-PSG) kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Kochi Health Sciences Center kn-affil= en-keyword=femoral neck fracture kn-keyword=femoral neck fracture en-keyword=intracapsular hip fracture kn-keyword=intracapsular hip fracture en-keyword=Garden alignment index kn-keyword=Garden alignment index en-keyword=posterior tilt kn-keyword=posterior tilt en-keyword=inter-rater reliability kn-keyword=inter-rater reliability en-keyword=intra-rater reliability kn-keyword=intra-rater reliability en-keyword=intraclass correlation coefficients kn-keyword=intraclass correlation coefficients END start-ver=1.4 cd-journal=joma no-vol=41 cd-vols= no-issue= article-no= start-page=9 end-page=19 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=試験研究 : 2018年度 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=23 article-no= start-page=15412 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221206 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Alterations in UPR Signaling by Methylmercury Trigger Neuronal Cell Death in the Mouse Brain en-subtitle= kn-subtitle= en-abstract= kn-abstract=Methylmercury (MeHg), an environmental toxicant, induces neuronal cell death and injures specific areas of the brain. MeHg is known to induce oxidative and endoplasmic reticulum (ER) stress. The unfolded protein response (UPR) pathway has a dual nature in that it regulates and protects cells from an overload of improperly folded proteins in the ER, whereas excessively stressed cells are eliminated by apoptosis. Oxidative stress/ER stress induced by methylmercury exposure may tilt the UPR toward apoptosis, but there is little in vivo evidence of a direct link to actual neuronal cell death. Here, by using the ER stress-activated indicator (ERAI) system, we investigated the time course signaling alterations of UPR in vivo in the most affected areas, the somatosensory cortex and striatum. In the ERAI-Venus transgenic mice exposed to MeHg (30 or 50 ppm in drinking water), the ERAI signal, which indicates the activation of the cytoprotective pathway of the UPR, was only transiently enhanced, whereas the apoptotic pathway of the UPR was persistently enhanced. Furthermore, detailed analysis following the time course showed that MeHg-induced apoptosis is strongly associated with alterations in UPR signaling. Our results suggest that UPR modulation could be a therapeutic target for treating neuropathy. en-copyright= kn-copyright= en-aut-name=NomuraRyosuke en-aut-sei=Nomura en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakasugiNobumasa en-aut-sei=Takasugi en-aut-mei=Nobumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiraokaHideki en-aut-sei=Hiraoka en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IijimaYuta en-aut-sei=Iijima en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwawakiTakao en-aut-sei=Iwawaki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KumagaiYoshito en-aut-sei=Kumagai en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujimuraMasatake en-aut-sei=Fujimura en-aut-mei=Masatake kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UeharaTakashi en-aut-sei=Uehara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Division of Cell Medicine, Department of Life Science, Medical Research Institute, Kanazawa Medical University kn-affil= affil-num=6 en-affil=Environmental Biology Laboratory, Faculty of Medicine, University of Tsukuba kn-affil= affil-num=7 en-affil=Department of Basic Medical Science, National Institute for Minamata Disease kn-affil= affil-num=8 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=methylmercury kn-keyword=methylmercury en-keyword=neuronal cell death kn-keyword=neuronal cell death en-keyword=endoplasmic reticulum stress kn-keyword=endoplasmic reticulum stress en-keyword=unfolded protein response kn-keyword=unfolded protein response en-keyword=ERAI system kn-keyword=ERAI system END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=4 article-no= start-page=45 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221029 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Involvement of a Basic Helix-Loop-Helix Gene BHLHE40 in Specification of Chicken Retinal Pigment Epithelium en-subtitle= kn-subtitle= en-abstract= kn-abstract=The first event of differentiation and morphogenesis in the optic vesicle (OV) is specification of the neural retina (NR) and retinal pigment epithelium (RPE), separating the inner and outer layers of the optic cup, respectively. Here, we focus on a basic helix-loop-helix gene, BHLHE40, which has been shown to be expressed by the developing RPE in mice and zebrafish. Firstly, we examined the expression pattern of BHLHE40 in the developing chicken eye primordia by in situ hybridization. Secondly, BHLHE40 overexpression was performed with in ovo electroporation and its effects on optic cup morphology and expression of NR and RPE marker genes were examined. Thirdly, we examined the expression pattern of BHLHE40 in LHX1-overexpressed optic cup. BHLHE40 expression emerged in a subset of cells of the OV at Hamburger and Hamilton stage 14 and became confined to the outer layer of the OV and the ciliary marginal zone of the retina by stage 17. BHLHE40 overexpression in the prospective NR resulted in ectopic induction of OTX2 and repression of VSX2. Conversely, BHLHE40 was repressed in the second NR after LHX1 overexpression. These results suggest that emergence of BHLHE40 expression in the OV is involved in initial RPE specification and that BHLHE40 plays a role in separation of the early OV domains by maintaining OTX2 expression and antagonizing an NR developmental program. en-copyright= kn-copyright= en-aut-name=KinuhataToshiki en-aut-sei=Kinuhata en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoKeita en-aut-sei=Sato en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BandoTetsuya en-aut-sei=Bando en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MitoTaro en-aut-sei=Mito en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyaishiSatoru en-aut-sei=Miyaishi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NohnoTsutomu en-aut-sei=Nohno en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OhuchiHideyo en-aut-sei=Ohuchi en-aut-mei=Hideyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Cytology and Histology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cytology and Histology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cytology and Histology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Bio-Innovation Research Center, Tokushima University kn-affil= affil-num=5 en-affil=Department of Legal Medicine, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cytology and Histology, Okayama University Medical School kn-affil= affil-num=7 en-affil=Department of Cytology and Histology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=basic helix-loop-helix e40 kn-keyword=basic helix-loop-helix e40 en-keyword=BHLHE40 kn-keyword=BHLHE40 en-keyword=LIM homeobox 1 kn-keyword=LIM homeobox 1 en-keyword=LHX1 kn-keyword=LHX1 en-keyword=chicken kn-keyword=chicken en-keyword=optic vesicle kn-keyword=optic vesicle en-keyword=retinal pigment epithelium kn-keyword=retinal pigment epithelium en-keyword=RPE kn-keyword=RPE en-keyword=neural retina kn-keyword=neural retina END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=3 article-no= start-page=1059 end-page=1073 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221116 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The secreted immune response peptide 1 functions as a phytocytokine in rice immunity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Small signalling peptides play important roles in various plant processes, but information regarding their involvement in plant immunity is limited. We previously identified a novel small secreted protein in rice, called immune response peptide 1 (IRP1). Here, we studied the function of IRP1 in rice immunity. Rice plants overexpressing IRP1 enhanced resistance to the virulent rice blast fungus. Application of synthetic IRP1 to rice suspension cells triggered the expression of IRP1 itself and the defence gene phenylalanine ammonia-lyase 1 (PAL1). RNA-seq results revealed that 84% of genes up-regulated by IRP1, including 13 OsWRKY transcription factors, were also induced by a microbe-associated molecular pattern (MAMP), chitin, indicating that IRP1 and chitin share a similar signalling pathway. Co-treatment with chitin and IRP1 elevated the expression level of PAL1 and OsWRKYs in an additive manner. The increased chitin concentration arrested the induction of IRP1 and PAL1 expression by IRP1, but did not affect IRP1-triggered mitogen-activated protein kinases (MAPKs) activation. Collectively, our findings indicate that IRP1 functions as a phytocytokine in rice immunity regulating MAPKs and OsWRKYs that can amplify chitin and other signalling pathways, and provide new insights into how MAMPs and phytocytokines cooperatively regulate rice immunity. en-copyright= kn-copyright= en-aut-name=WangPingyu en-aut-sei=Wang en-aut-mei=Pingyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=JiaHuimin en-aut-sei=Jia en-aut-mei=Huimin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GuoTing en-aut-sei=Guo en-aut-mei=Ting kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZhangYuanyuan en-aut-sei=Zhang en-aut-mei=Yuanyuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WangWanqing en-aut-sei=Wang en-aut-mei=Wanqing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishimuraHideki en-aut-sei=Nishimura en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=LiZhengguo en-aut-sei=Li en-aut-mei=Zhengguo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawanoYoji en-aut-sei=Kawano en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Key Laboratory of Plant Hormones and Development Regulation of Chongqing, School of Life Sciences, Chongqing University kn-affil= affil-num=2 en-affil=Shanghai Center for Plant Stress Biology and Center of Excellence for Molecular Plant Sciences, Chinese Academy of Sciences kn-affil= affil-num=3 en-affil=Shanghai Center for Plant Stress Biology and Center of Excellence for Molecular Plant Sciences, Chinese Academy of Sciences kn-affil= affil-num=4 en-affil=Shanghai Center for Plant Stress Biology and Center of Excellence for Molecular Plant Sciences, Chinese Academy of Sciences 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= affil-num=7 en-affil=Key Laboratory of Plant Hormones and Development Regulation of Chongqing, School of Life Sciences, Chongqing University kn-affil= affil-num=8 en-affil=Shanghai Center for Plant Stress Biology and Center of Excellence for Molecular Plant Sciences, Chinese Academy of Sciences kn-affil= en-keyword=Immunity kn-keyword=Immunity en-keyword=IRP1 kn-keyword=IRP1 en-keyword=pattern-triggered immunity kn-keyword=pattern-triggered immunity en-keyword=phytocytokine kn-keyword=phytocytokine en-keyword=Pyricularia oryzae kn-keyword=Pyricularia oryzae en-keyword=rice kn-keyword=rice 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=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=13 cd-vols= no-issue= article-no= start-page=1004184 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220915 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Time-series transcriptome of Brachypodium distachyon during bacterial flagellin-induced pattern-triggered immunity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Plants protect themselves from microorganisms by inducing pattern-triggered immunity (PTI) via recognizing microbe-associated molecular patterns (MAMPs), conserved across many microbes. Although the MAMP perception mechanism and initial events during PTI have been well-characterized, knowledge of the transcriptomic changes in plants, especially monocots, is limited during the intermediate and terminal stages of PTI. Here, we report a time-series high-resolution RNA-sequencing (RNA-seq) analysis during PTI in the leaf disks of Brachypodium distachyon. We identified 6,039 differentially expressed genes (DEGs) in leaves sampled at 0, 0.5, 1, 3, 6, and 12 hours after treatment (hat) with the bacterial flagellin peptide flg22. The k-means clustering method classified these DEGs into 10 clusters (6 upregulated and 4 downregulated). Based on the results, we selected 10 PTI marker genes in B. distachyon. Gene ontology (GO) analysis suggested a tradeoff between defense responses and photosynthesis during PTI. The data indicated the recovery of photosynthesis started at least at 12 hat. Over-representation analysis of transcription factor genes and cis-regulatory elements in DEG promoters implied the contribution of 12 WRKY transcription factors in plant defense at the early stage of PTI induction. en-copyright= kn-copyright= en-aut-name=OgasaharaTsubasa en-aut-sei=Ogasahara en-aut-mei=Tsubasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KouzaiYusuke en-aut-sei=Kouzai en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeMegumi en-aut-sei=Watanabe en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakahashiAkihiro en-aut-sei=Takahashi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahagiKotaro en-aut-sei=Takahagi en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KimJune-Sik en-aut-sei=Kim en-aut-mei=June-Sik kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuiHidenori en-aut-sei=Matsui en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamamotoMikihiro en-aut-sei=Yamamoto en-aut-mei=Mikihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ToyodaKazuhiro en-aut-sei=Toyoda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IchinoseYuki en-aut-sei=Ichinose en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MochidaKeiichi en-aut-sei=Mochida en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NoutoshiYoshiteru en-aut-sei=Noutoshi en-aut-mei=Yoshiteru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Kihara Institute for Biological Research, Yokohama City University kn-affil= affil-num=6 en-affil=Bioproductivity Informatics Research Team, RIKEN Center for Sustainable Resource Science kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=9 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=10 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=11 en-affil=Bioproductivity Informatics Research Team, RIKEN Center for Sustainable Resource Science kn-affil= affil-num=12 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Brachypodium distachyon kn-keyword=Brachypodium distachyon en-keyword=monocotyledonous plant kn-keyword=monocotyledonous plant en-keyword=microbe-associated molecular pattern kn-keyword=microbe-associated molecular pattern en-keyword=time-series transcriptome analysis kn-keyword=time-series transcriptome analysis en-keyword=reactive oxygen species kn-keyword=reactive oxygen species en-keyword=pattern-triggered immunity kn-keyword=pattern-triggered immunity END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202297 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy and Safety of Esaxerenone in Hypertensive Patients with Diabetic Kidney Disease: A Multicenter, Open-Label, Prospective Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction
Clinical data of esaxerenone in hypertensive patients with diabetic kidney disease (DKD) are lacking. We evaluated the efficacy and safety of esaxerenone in patients with DKD and an inadequate response to blood pressure (BP)-lowering treatment.

Methods
In this multicenter, open-label, prospective study, patients were divided into urinary albumin-to-creatinine ratio subcohorts (UACR?
Results
In total, 113 patients were enrolled. Morning home SBP/DBP significantly decreased from baseline to EOT in the total population (??11.6/??5.2 mmHg, both p?
Conclusion
Esaxerenone demonstrated a BP-lowering effect and improved albuminuria. The effects were consistent regardless of the severity of albuminuria without clinically relevant serum potassium elevation and eGFR reduction. en-copyright= kn-copyright= 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=1 ORCID= en-aut-name=NakajimaHirofumi en-aut-sei=Nakajima en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HashimotoMasami en-aut-sei=Hashimoto en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakamuraAkihiko en-aut-sei=Nakamura en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NunoueTomokazu en-aut-sei=Nunoue en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MurakamiKazuharu en-aut-sei=Murakami en-aut-mei=Kazuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HosoyaTakeshi en-aut-sei=Hosoya en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KomotoKiichi en-aut-sei=Komoto en-aut-mei=Kiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TaguchiTakashi en-aut-sei=Taguchi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AkasakaTakaaki en-aut-sei=Akasaka en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ShiosakaiKazuhito en-aut-sei=Shiosakai en-aut-mei=Kazuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=SugimotoKotaro en-aut-sei=Sugimoto en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 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 Internal Medicine, Nakashima Hospital kn-affil= affil-num=3 en-affil=Hashimoto Kidney Clinic kn-affil= affil-num=4 en-affil=Osafune Clinic kn-affil= affil-num=5 en-affil=Nunoue Clinic kn-affil= affil-num=6 en-affil=Murakami Clinic kn-affil= affil-num=7 en-affil=Hosoya Clinic kn-affil= affil-num=8 en-affil=Innoshima General Hospital kn-affil= affil-num=9 en-affil=Primary Medical Science Department, Daiichi Sankyo Co., Ltd. kn-affil= affil-num=10 en-affil=Primary Medical Science Department, Daiichi Sankyo Co., Ltd. kn-affil= affil-num=11 en-affil=Data Intelligence Department, Daiichi Sankyo Co., Ltd. kn-affil= affil-num=12 en-affil=Primary Medical Science Department, Daiichi Sankyo Co., Ltd. kn-affil= affil-num=13 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=60 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220912 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Exosomal Wnt7a from a low metastatic subclone promotes lung metastasis of a highly metastatic subclone in the murine 4t1 breast cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Patients with triple-negative breast cancer (TNBC) often have poorer prognosis than those with other subtypes because of its aggressive behaviors. Cancer cells are heterogeneous, and only a few highly metastatic subclones metastasize. Although the majority of subclones may not metastasize, they could contribute by releasing factors that increase the capacity of highly metastatic cells and/or provide a favorable tumor microenvironment (TME). Here, we analyzed the interclonal communication in TNBC which leads to efficient cancer progression, particularly lung metastasis, using the polyclonal murine 4T1 BC model. Methods We isolated two 4T1 subclones, LM.4T1 and HM.4T1 cells with a low and a high metastatic potential, respectively, and examined the effects of LM.4T1 cells on the behaviors of HM.4T1 cells using the cell scratch assay, sphere-forming assay, sphere invasion assay, RT-qPCR, and western blotting in vitro. We also examined the contribution of LM.4T1 cells to the lung metastasis of HM.4T1 cells and TME in vivo. To identify a critical factor which may be responsible for the effects by LM.4T1 cells, we analyzed the data obtained from the GEO database. Results Co-injection of LM.4T1 cells significantly augmented lung metastases by HM.4T1 cells. LM.4T1-derived exosomes promoted the migration and invasion of HM.4T1 cells in vitro, and blocking the secretion of exosome abrogated their effects on HM.4T1 cells. Analyses of data obtained from the GEO database suggested that Wnt7a might be a critical factor responsible for the enhancing effects. In fact, a higher level of Wnt7a was detected in LM.4T1 cells, especially in exosomes, than in HM.4T1 cells, and deletion of Wnt7a in LM.4T1 cells significantly decreased the lung metastasis of HM.4T1 cells. Further, treatment with Wnt7a increased the spheroid formation by HM.4T1 cells via activation of the PI3K/Akt/mTOR signaling pathway. Finally, infiltration of alpha SMA-positive fibroblasts and angiogenesis was more prominent in tumors of LM.4T1 cells and deletion of Wnt7a in LM.4T1 cells markedly reduced angiogenesis. Conclusions We demonstrated, for the first time, that a low metastatic subclone can enhance lung metastasis of highly metastatic subclone via exosomal Wnt7a and propose Wnt7a as a molecular target to treat TNBC patients. en-copyright= kn-copyright= en-aut-name=LiChunning en-aut-sei=Li en-aut-mei=Chunning kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshimuraTeizo en-aut-sei=Yoshimura en-aut-mei=Teizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TianMiao en-aut-sei=Tian en-aut-mei=Miao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangYuze en-aut-sei=Wang en-aut-mei=Yuze kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KondoTakamasa en-aut-sei=Kondo en-aut-mei=Takamasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamamotoKen-Ichi en-aut-sei=Yamamoto en-aut-mei=Ken-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujisawaMasayoshi en-aut-sei=Fujisawa en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SakaguchiMasakiyo en-aut-sei=Sakaguchi en-aut-mei=Masakiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Cell Biology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Breast cancer kn-keyword=Breast cancer en-keyword=Metastasis kn-keyword=Metastasis en-keyword=Exosomes kn-keyword=Exosomes en-keyword=Epithelial mesenchymal transition kn-keyword=Epithelial mesenchymal transition en-keyword=Tumor microenvironment kn-keyword=Tumor microenvironment END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=8 article-no= start-page=1253 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220819 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Novel Lung Growth Strategy with Biological Therapy Targeting Airway Remodeling in Childhood Bronchial Asthma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Anti-inflammatory therapy, centered on inhaled steroids, suppresses airway inflammation in asthma, reduces asthma mortality and hospitalization rates, and achieves clinical remission in many pediatric patients. However, the spontaneous remission rate of childhood asthma in adulthood is not high, and airway inflammation and airway remodeling persist after remission of asthma symptoms. Childhood asthma impairs normal lung maturation, interferes with peak lung function in adolescence, reduces lung function in adulthood, and increases the risk of developing chronic obstructive pulmonary disease (COPD). Early suppression of airway inflammation in childhood and prevention of asthma exacerbations may improve lung maturation, leading to good lung function and prevention of adult COPD. Biological drugs that target T-helper 2 (Th2) cytokines are used in patients with severe pediatric asthma to reduce exacerbations and airway inflammation and improve respiratory function. They may also suppress airway remodeling in childhood and prevent respiratory deterioration in adulthood, reducing the risk of COPD and improving long-term prognosis. No studies have demonstrated a suppressive effect on airway remodeling in childhood severe asthma, and further clinical trials using airway imaging analysis are needed to ascertain the inhibitory effect of biological drugs on airway remodeling in severe childhood asthma. In this review, we describe the natural prognosis of lung function in childhood asthma and the risk of developing adult COPD, the pathophysiology of allergic airway inflammation and airway remodeling via Th2 cytokines, and the inhibitory effect of biological drugs on airway remodeling in childhood asthma. en-copyright= kn-copyright= en-aut-name=TsugeMitsuru en-aut-sei=Tsuge en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkedaMasanori en-aut-sei=Ikeda en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Pediatric Acute Diseases, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Okayama University School of Medicine kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=bronchial asthma kn-keyword=bronchial asthma en-keyword=chronic obstructive pulmonary disease kn-keyword=chronic obstructive pulmonary disease en-keyword=lung function trajectory kn-keyword=lung function trajectory en-keyword=type 2 inflammation kn-keyword=type 2 inflammation en-keyword=airway remodeling kn-keyword=airway remodeling en-keyword=omalizumab kn-keyword=omalizumab en-keyword=mepolizumab kn-keyword=mepolizumab en-keyword=benralizumab kn-keyword=benralizumab en-keyword=dupilumab kn-keyword=dupilumab END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=12353 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220719 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Treatment resistance of rheumatoid arthritis relates to infection of periodontal pathogenic bacteria: a case-control cross-sectional study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recent studies have shown that periodontitis is associated with rheumatoid arthritis (RA) and periodontal bacteria, such as Aggregatibacter actinomycetemcomitans (Aa) and Porphyromonas gingivalis (Pg) are involved in the pathogenesis of RA via citrullinated proteins. Smoking has also been shown to be involved in the pathogenesis of RA; however, the extent of this involvement is still poorly understood. In addition, RA and polymyalgia rheumatica (PMR) are sometimes difficult to differentiate; however, the relationship between PMR and the factors from smoking and periodontal bacteria is unclear. The aim of this study was to clarify the relationship between periodontal pathogenic bacterial infections and smoking in patients with RA or PMR. This case-control study included 142 patients with untreated RA or PMR. This study evaluated the serum antibody titers against periodontal pathogenic bacterial antigens and an anti-citrullinated peptide antibody (ACPA). In patients with RA, the relationship between antibody titers and disease activity of RA and response after 3 months of treatment was also investigated. Additionally, the effects of smoking were evaluated. Although there was no significant difference in serum antibody titer against periodontal pathogenic bacteria between the ACPA-positive RA group and the ACPA-negative PMR group, we found an association between the elevated antibody titer against Pg and the degree of ACPA value, especially between negative group and high-value positive group (>= 100 U/mL). The antibody titers against Aa and Pg did not differ depending on disease activity score 28 (DAS28) at baseline; however, patients with high antibody titers had poor RA therapeutic response as judged by DAS28 after 3 months. We could not find any association between smoking and any of these parameters. Periodontal pathogenic bacteria, especially Pg, are associated with elevated ACPA levels. Our findings suggest that Pg and Aa infections interfere with the therapeutic response of RA. en-copyright= kn-copyright= en-aut-name=Takeuchi-HatanakaKazu en-aut-sei=Takeuchi-Hatanaka en-aut-mei=Kazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KoyamaYoshinobu en-aut-sei=Koyama en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkamotoKentaro en-aut-sei=Okamoto en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakaidaKyosuke en-aut-sei=Sakaida en-aut-mei=Kyosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoTadashi en-aut-sei=Yamamoto en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Periodontics and Endodontics, Okayama University Hospital kn-affil= affil-num=2 en-affil=Center for Autoimmune Diseases, Division of Rheumatology, Japan Red Cross Okayama Hospital kn-affil= affil-num=3 en-affil=Department of Periodontics and Endodontics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Periodontics and Endodontics, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Pathophysiology?Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pathophysiology?Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue= article-no= start-page=904215 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220630 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pemafibrate Prevents Rupture of Angiotensin II-Induced Abdominal Aortic Aneurysms en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Abdominal aortic aneurysm (AAA) is a life-threatening disease that lacks effective preventive therapies. This study aimed to evaluate the effect of pemafibrate, a selective peroxisome proliferator-activated receptor alpha (PPAR alpha) agonist, on AAA formation and rupture.
Methods: Experimental AAA was induced by subcutaneous angiotensin II (AngII) infusion in ApoE(-)(/)(-) mice for 4 weeks. Pemafibrate (0.1 mg/kg/day) was administered orally. Dihydroethidium staining was used to evaluate the reactive oxygen species (ROS).
Results: The size of the AngII-induced AAA did not differ between pemafibrate- and vehicle-treated groups. However, a decreased mortality rate due to AAA rupture was observed in pemafibrate-treated mice. Pemafibrate ameliorated AngII-induced ROS and reduced the mRNA expression of interleukin-6 and tumor necrosis factor-alpha in the aortic wall. Gelatin zymography analysis demonstrated significant inhibition of matrix metalloproteinase-2 activity by pemafibrate. AngII-induced ROS production in human vascular smooth muscle cells was inhibited by pre-treatment with pemafibrate and was accompanied by an increase in catalase activity. Small interfering RNA-mediated knockdown of catalase or PPAR alpha significantly attenuated the anti-oxidative effect of pemafibrate.
Conclusion: Pemafibrate prevented AAA rupture in a murine model, concomitant with reduced ROS, inflammation, and extracellular matrix degradation in the aortic wall. The protective effect against AAA rupture was partly mediated by the anti-oxidative effect of catalase induced by pemafibrate in the smooth muscle cells. en-copyright= kn-copyright= en-aut-name=AmiokaNaofumi en-aut-sei=Amioka en-aut-mei=Naofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YonezawaTomoko en-aut-sei=Yonezawa en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KondoMegumi en-aut-sei=Kondo en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AkagiSatoshi en-aut-sei=Akagi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshidaMasashi en-aut-sei=Yoshida en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaitoYukihiro en-aut-sei=Saito en-aut-mei=Yukihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Molecular Biology and Biochemistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=pemafibrate kn-keyword=pemafibrate en-keyword=angiotensin II kn-keyword=angiotensin II en-keyword=abdominal aortic aneurysm kn-keyword=abdominal aortic aneurysm en-keyword=oxidative stress kn-keyword=oxidative stress en-keyword=catalase kn-keyword=catalase END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=12 article-no= start-page=6847 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220620 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Control of STING Agonistic/Antagonistic Activity Using Amine-Skeleton-Based c-di-GMP Analogues en-subtitle= kn-subtitle= en-abstract= kn-abstract=Stimulator of Interferon Genes (STING) is a type of endoplasmic reticulum (ER)-membrane receptor. STING is activated by a ligand binding, which leads to an enhancement of the immune-system response. Therefore, a STING ligand can be used to regulate the immune system in therapeutic strategies. However, the natural (or native) STING ligand, cyclic-di-nucleotide (CDN), is unsuitable for pharmaceutical use because of its susceptibility to degradation by enzymes and its low cell-membrane permeability. In this study, we designed and synthesized CDN derivatives by replacing the sugar-phosphodiester moiety, which is responsible for various problems of natural CDNs, with an amine skeleton. As a result, we identified novel STING ligands that activate or inhibit STING. The cyclic ligand 7, with a cyclic amine structure containing two guanines, was found to have agonistic activity, whereas the linear ligand 12 showed antagonistic activity. In addition, these synthetic ligands were more chemically stable than the natural ligands. en-copyright= kn-copyright= en-aut-name=YanaseYuta en-aut-sei=Yanase en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujiGenichiro en-aut-sei=Tsuji en-aut-mei=Genichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraMiki en-aut-sei=Nakamura en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShibataNorihito en-aut-sei=Shibata en-aut-mei=Norihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DemizuYosuke en-aut-sei=Demizu en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=National Institute of Health Sciences kn-affil= affil-num=2 en-affil=National Institute of Health Sciences kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Division of Pharmaceutical Science of Okayama University kn-affil= affil-num=4 en-affil=National Institute of Health Sciences kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Division of Pharmaceutical Science of Okayama University kn-affil= en-keyword=STING kn-keyword=STING en-keyword=cyclic dinucleotide kn-keyword=cyclic dinucleotide en-keyword=amines kn-keyword=amines en-keyword=drug design kn-keyword=drug design en-keyword=agonist kn-keyword=agonist en-keyword=antagonist kn-keyword=antagonist END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=228 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220530 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Adenomatoid mesothelioma arising from the diaphragm: a case report and review of the literature en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Adenomatoid mesothelioma is a rare subtype of malignant mesothelioma that can be confused with adenomatoid tumors, which are classified as benign. The clinical features and optimal management of adenomatoid mesothelioma have not been elucidated in the literature. In this report, we present an extremely rare case of adenomatoid mesothelioma that developed on the peritoneal surface of the diaphragm as well as a literature review of adenomatoid mesothelioma in the abdominal cavity. Case presentation The patient was a 61-year-old Japanese woman who had undergone resection of a malignant peripheral nerve sheath tumor of the hand 18 years prior. She was diagnosed with clinical stage I lung adenocarcinoma on follow-up chest radiography. Simultaneously, a 20-mm enhancing nodule with slow growth on the right diaphragm was detected on contrast-enhanced computed tomography. She presented no specific clinical symptoms. At this point, the lesion was suspected to be a hypervascular tumor of borderline malignancy, such as a solitary fibrous tumor. After a left upper lobectomy for lung adenocarcinoma, she was referred to our department, and laparoscopic tumor resection was performed. Adenomatoid tumors were also considered based on the histopathological and immunohistochemical analyses, but we made the final diagnosis of adenomatoid mesothelioma using the results of the genetic profile. The patient remains alive, with no recurrence noted 6 months after surgery. Conclusion We encountered a valuable case of adenomatoid mesothelioma of peritoneal origin. There are some previously reported cases of adenomatoid mesothelioma and adenomatoid tumors that may need to be recategorized according to the current classification. It is important to accumulate and share new findings to clarify the clinicopathological characteristics and genetic status of adenomatoid mesothelioma. en-copyright= kn-copyright= en-aut-name=KawabeKenta en-aut-sei=Kawabe en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoHiroki en-aut-sei=Sato en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KitanoAkiko en-aut-sei=Kitano en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaRyuichi en-aut-sei=Yoshida en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UmedaYuzo en-aut-sei=Umeda en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshidaKazuhiro en-aut-sei=Yoshida en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KumanoKenjiro en-aut-sei=Kumano en-aut-mei=Kenjiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KagouraMasaaki en-aut-sei=Kagoura en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YagiTakahito en-aut-sei=Yagi en-aut-mei=Takahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Center for Graduate Medical Education, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= en-keyword=Adenomatoid mesothelioma kn-keyword=Adenomatoid mesothelioma en-keyword=Adenomatoid tumor kn-keyword=Adenomatoid tumor en-keyword=Mesothelial tumor kn-keyword=Mesothelial tumor en-keyword=Diaphragm kn-keyword=Diaphragm en-keyword=Peritoneal kn-keyword=Peritoneal END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=5 article-no= start-page=924 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Helical Foldamers and Stapled Peptides as New Modalities in Drug Discovery: Modulators of Protein-Protein Interactions en-subtitle= kn-subtitle= en-abstract= kn-abstract=A "foldamer" is an artificial oligomeric molecule with a regular secondary or tertiary structure consisting of various building blocks. A "stapled peptide" is a peptide with stabilized secondary structures, in particular, helical structures by intramolecular covalent side-chain cross-linking. Helical foldamers and stapled peptides are potential drug candidates that can target protein-protein interactions because they enable multipoint molecular recognition, which is difficult to achieve with low-molecular-weight compounds. This mini-review describes a variety of peptide-based foldamers and stapled peptides with a view to their applications in drug discovery, including our recent progress. en-copyright= kn-copyright=

localization and immune induction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nucleotide-binding leucine-rich repeat (NLR) proteins work as crucial intracellular immune receptors. N-terminal domains of NLRs fall into two groups, coiled-coil (CC) and Toll-interleukin 1 receptor domains, which play critical roles in signal transduction and disease resistance. However, the activation mechanisms of NLRs, and how their N-termini function in immune induction, remain largely unknown. Here, we revealed that the CC domain of a rice NLR Pit contributes to self-association. The Pit CC domain possesses three conserved hydrophobic residues that are known to be involved in oligomer formation in two NLRs, barley MLA10 and Arabidopsis RPM1. Interestingly, the function of these residues in Pit differs from that in MLA10 and RPM1. Although three hydrophobic residues are important for Pit-induced disease resistance against rice blast fungus, they do not participate in self-association or binding to downstream signalling molecules. By homology modelling of Pit using the Arabidopsis ZAR1 structure, we tried to clarify the role of three conserved hydrophobic residues and found that they are located in the predicted α2-helix of the Pit CC domain and involved in the plasma membrane localization. Our findings provide novel insights for understanding the mechanisms of NLR activation as well as the relationship between subcellular localization and immune induction. en-copyright= kn-copyright= en-aut-name=WangQiong en-aut-sei=Wang en-aut-mei=Qiong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LiYuying en-aut-sei=Li en-aut-mei=Yuying kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KosamiKen‐ichi en-aut-sei=Kosami en-aut-mei=Ken‐ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LiuChaochao en-aut-sei=Liu en-aut-mei=Chaochao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=LiJing en-aut-sei=Li en-aut-mei=Jing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ZhangDan en-aut-sei=Zhang en-aut-mei=Dan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MikiDaisuke en-aut-sei=Miki en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawanoYoji en-aut-sei=Kawano en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=School of Horticulture and Plant Protection Yangzhou University Yangzhou China kn-affil= affil-num=2 en-affil=CAS Center for Excellence in Molecular Plant Sciences, Shanghai Center for Plant Stress Biology Chinese Academy of Sciences Shanghai China kn-affil= affil-num=3 en-affil=CAS Center for Excellence in Molecular Plant Sciences, Shanghai Center for Plant Stress Biology Chinese Academy of Sciences Shanghai China kn-affil= affil-num=4 en-affil=School of Biotechnology Jiangsu University of Science and Technology Zhenjiang China kn-affil= affil-num=5 en-affil=CAS Center for Excellence in Molecular Plant Sciences, Shanghai Center for Plant Stress Biology Chinese Academy of Sciences Shanghai China kn-affil= affil-num=6 en-affil=School of Horticulture and Plant Protection Yangzhou University Yangzhou China kn-affil= affil-num=7 en-affil=CAS Center for Excellence in Molecular Plant Sciences, Shanghai Center for Plant Stress Biology Chinese Academy of Sciences Shanghai China kn-affil= affil-num=8 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=NLR protein kn-keyword=NLR protein en-keyword=plasma membrane localization kn-keyword=plasma membrane localization en-keyword=self-association kn-keyword=self-association en-keyword=effector triggered immunity kn-keyword=effector triggered immunity en-keyword=rice kn-keyword=rice END start-ver=1.4 cd-journal=joma no-vol=167 cd-vols= no-issue=4 article-no= start-page=1201 end-page=1204 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202234 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A novel deltapartitivirus from red clover en-subtitle= kn-subtitle= en-abstract= kn-abstract=The family Partitiviridae has five genera, among which is the genus Deltapartitivirus. We report here the complete genome sequence of a deltapartitivirus from red clover, termed “red clover cryptic virus 3” (RCCV3). RCCV3 has a bisegmented double-stranded (ds) RNA genome. dsRNA1 and dsRNA2 are 1580 and 1589 nucleotides (nt) in length and are predicted to encode an RNA-directed RNA polymerase (RdRP) and a capsid protein (CP), respectively. The RCCV3 RdRP shares the highest sequence identity with the RdRP of a previously reported deltapartitivirus, Medicago sativa deltapartitivirus 1 (MsDPV1) (76.5%), while the RCCV3 CP shows 50% sequence identity to the CP of MsDPV1. RdRP- and CP-based phylogenetic trees place RCCV3 into a clade of deltapartitiviruses. The sequence and phylogenetic analyses clearly indicate that RCCV3 represents a new species in the genus Deltapartitivirus. RCCV3 was detectable in all three tested cultivars of red clover. en-copyright= kn-copyright= en-aut-name=TelengechPaul en-aut-sei=Telengech en-aut-mei=Paul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShahiSabitree en-aut-sei=Shahi en-aut-mei=Sabitree kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuzukiNobuhiro en-aut-sei=Suzuki en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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= END start-ver=1.4 cd-journal=joma no-vol=111 Supplement cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Proceedings of the International Symposium on Animal Bioscience 2021 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=111 cd-vols= no-issue= article-no= start-page=27 end-page=42 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The List of Published by Members of the Faculty From January to December 2021 kn-title=公表学術論文等リスト 2021 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=2 article-no= start-page=105 end-page=127 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220117 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Plant viruses and viroids in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=An increasing number of plant viruses and viroids have been reported from all over the world due largely to metavirogenomics approaches with technological innovation. Herein, the official changes of virus taxonomy, including the establishment of megataxonomy and amendments of the codes of virus classification and nomenclature, recently made by the International Committee on Taxonomy of Viruses were summarized. The continued efforts of the plant virology community of Japan to index all plant viruses and viroids occurring in Japan, which represent 407 viruses, including 303 virus species and 104 unclassified?viruses, and 25 viroids, including 20 species and 5 unclassified viroids, as of October 2021, were also introduced. These viruses and viroids are collectively classified into 81 genera within 26 families of 3 kingdoms (Shotokuvirae, Orthornavirae, Pararnavirae) across 2 realms (Monodnaviria and Riboviria). This review also overviewed how Japan’s plant virus/viroid studies have contributed to advance virus/viroid taxonomy. en-copyright= kn-copyright= en-aut-name=FujiShin-ichi en-aut-sei=Fuji

system YbFe2O4 with electrochemical Li+ intercalation en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report an attempt valence control of the mixed valence iron triangular oxide YbFe2O4 to develop an effective technique controling the frustration of charges in strongly correlated electron systems. The electrochemical doping of Li + into YbFe2O4 was examined on a cell-type sample similar to the Li-ion secondary battery cell. Systematic changes in the lattice constant and Fe ? Fe and Fe?Yb distance were observed with Li doping. Maximum value of the doping was over 300 mAh/g. An EXAFS experiment indicated that Li positioned between Yb octahedron layer (U-layer) and Fe-bipyramidal layer (W-layer). However, detailed change of iron valence state of YbFe2O4was not clearly observed because of the superimpose of the signal from iron metal nano particles in XANES observation. We discuss that the uncertainty might arise from the inhomogeneous distribution of the sample particle size, which might prevent the homogeneous doping of Li because the doping occurs on the surface of each nano-particles. en-copyright= kn-copyright= en-aut-name=MuraseS. en-aut-sei=Murase en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshikawaY. en-aut-sei=Yoshikawa en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiwaraK. en-aut-sei=Fujiwara en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukadaY. en-aut-sei=Fukada en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TeranishiT. en-aut-sei=Teranishi en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KanoJ. en-aut-sei=Kano en-aut-mei=J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujiiT. en-aut-sei=Fujii en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=InadaY. en-aut-sei=Inada en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KatayamaM. en-aut-sei=Katayama en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YoshiiK. en-aut-sei=Yoshii en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TsujiT. en-aut-sei=Tsuji en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MatsumuraD. en-aut-sei=Matsumura en-aut-mei=D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=IkedaN. en-aut-sei=Ikeda en-aut-mei=N. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=College of Life Sciences, Ritsumeikan University kn-affil= affil-num=9 en-affil=College of Life Sciences, Ritsumeikan University kn-affil= affil-num=10 en-affil=Japan Atomic Energy Agency kn-affil= affil-num=11 en-affil=Japan Atomic Energy Agency kn-affil= affil-num=12 en-affil=Japan Atomic Energy Agency kn-affil= affil-num=13 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=RFe2O4 kn-keyword=RFe2O4 en-keyword=YbFe2O4 kn-keyword=YbFe2O4 en-keyword=Triangular lattice kn-keyword=Triangular lattice en-keyword=Charge frustration kn-keyword=Charge frustration en-keyword=Spin frustration kn-keyword=Spin frustration en-keyword=Orbital frustration kn-keyword=Orbital frustration en-keyword=Frustration control kn-keyword=Frustration control en-keyword=Li doping kn-keyword=Li doping END start-ver=1.4 cd-journal=joma no-vol=62 cd-vols= no-issue=11 article-no= start-page=1662 end-page=1675 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021827 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Small GTPase OsRac1 Forms Two Distinct Immune Receptor Complexes Containing the PRR OsCERK1 and the NLR Pit en-subtitle= kn-subtitle= en-abstract= kn-abstract=Plants employ two different types of immune receptors, cell surface pattern recognition receptors (PRRs) and intracellular nucleotide-binding and leucine-rich repeat-containing proteins (NLRs), to cope with pathogen invasion. Both immune receptors often share similar downstream components and responses but it remains unknown whether a PRR and an NLR assemble into the same protein complex or two distinct receptor complexes. We have previously found that the small GTPase OsRac1 plays key roles in the signaling of OsCERK1, a PRR for fungal chitin, and of Pit, an NLR for rice blast fungus, and associates directly and indirectly with both of these immune receptors. In this study, using biochemical and bioimaging approaches, we revealed that OsRac1 formed two distinct receptor complexes with OsCERK1 and with Pit. Supporting this result, OsCERK1 and Pit utilized different transport systems for anchorage to the plasma membrane (PM). Activation of OsCERK1 and Pit led to OsRac1 activation and, concomitantly, OsRac1 shifted from a small to a large protein complex fraction. We also found that the chaperone Hsp90 contributed to the proper transport of Pit to the PM and the immune induction of Pit. These findings illuminate how the PRR OsCERK1 and the NLR Pit orchestrate rice immunity through the small GTPase OsRac1. en-copyright= kn-copyright= en-aut-name=AkamatsuAkira en-aut-sei=Akamatsu en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiwaraMasayuki en-aut-sei=Fujiwara en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamadaSatoshi en-aut-sei=Hamada en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WakabayashiMegumi en-aut-sei=Wakabayashi en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YaoAi en-aut-sei=Yao en-aut-mei=Ai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WangQiong en-aut-sei=Wang en-aut-mei=Qiong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KosamiKen-ichi en-aut-sei=Kosami en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=DangThu Thi en-aut-sei=Dang en-aut-mei=Thu Thi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=Kaneko-KawanoTakako en-aut-sei=Kaneko-Kawano en-aut-mei=Takako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FukadaFumi en-aut-sei=Fukada en-aut-mei=Fumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ShimamotoKo en-aut-sei=Shimamoto en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KawanoYoji en-aut-sei=Kawano en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Biosciences, Kwansei Gakuin University kn-affil= affil-num=2 en-affil=Graduate School of Biological Sciences, Nara Institute of Science and Technology kn-affil= affil-num=3 en-affil=Graduate School of Biological Sciences, Nara Institute of Science and Technology kn-affil= affil-num=4 en-affil=Graduate School of Biological Sciences, Nara Institute of Science and Technology kn-affil= affil-num=5 en-affil=Graduate School of Biological Sciences, Nara Institute of Science and Technology kn-affil= affil-num=6 en-affil=Department of Horticulture and Plant Protection kn-affil= affil-num=7 en-affil=CAS Center for Excellence in Molecular Plant Sciences, Shanghai Center for Plant Stress Biology, Chinese Academy of Sciences kn-affil= affil-num=8 en-affil=Graduate School of Biological Sciences, Nara Institute of Science and Technology kn-affil= affil-num=9 en-affil=College of Pharmaceutical Sciences, Ritsumeikan University kn-affil= affil-num=10 en-affil=Institute of Plant Science and Resources kn-affil= affil-num=11 en-affil=Graduate School of Biological Sciences, Nara Institute of Science and Technology kn-affil= affil-num=12 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=014010 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211229 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of nitrogen loading in the last 80 years in an urbanized Asian coastal catchment through the reconstruction of severe contamination period en-subtitle= kn-subtitle= en-abstract= kn-abstract=Most semi-enclosed seas have experienced severe eutrophication owing to high nutrient loading from rivers during rapid population growth periods. In Japan, the coastal areas of some megacities (e.g. Tokyo and Osaka) experienced considerable economic growth during the 1960s-1970s. Therefore, determining the amount of nutrient loading during this period is essential to undertake measures for the conservation of coastal environments. However, determining the nutrient loading that occurred several decades ago is generally difficult owing to lacking water quality records. In this study, the nitrogen loading in the Yamato River catchment, an urbanized coastal catchment in Asia, for 80 years from the 1940s to the 2010s is reconstructed using the Soil and Water Assessment Tool. We considered factors such as population growth, wastewater treatment plant (WWTP) construction, and changes in land and fertilizer usage in different urbanization stages. Results show that the total nitrogen loading in the catchment peaked in the 1970s at 6616 tons yr(-1) owing to untreated wastewater discharge and rapid increase in population growth. By reducing 57% of the nitrogen loading in the 2010s from the catchment, WWTPs have been instrumental in improving the water environment. The decrease in and integration of agricultural land has reduced nitrogen loading attributed to nonpoint sources; however, this reduction was not obvious because of the high fertilizer usage before the 2000s. Overall, the findings of this study provide a comprehensive understanding of the impact of rapid urbanization in an Asian coastal catchment on nitrogen loading during the high economic growth period in the past. This study will be useful for the long-term assessment of nutrient loading in other. en-copyright= kn-copyright= en-aut-name=WangKunyang en-aut-sei=Wang en-aut-mei=Kunyang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OnoderaShin-Ichi en-aut-sei=Onodera en-aut-mei=Shin-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SaitoMitsuyo en-aut-sei=Saito en-aut-mei=Mitsuyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Integrated Arts and Sciences, Hiroshima University kn-affil= affil-num=2 en-affil=Graduate School of Advanced Science and Engineering, Hiroshima University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=long-term kn-keyword=long-term en-keyword=nitrogen loading kn-keyword=nitrogen loading en-keyword=rapid urbanization kn-keyword=rapid urbanization en-keyword=popilation growth kn-keyword=popilation growth en-keyword=land use change kn-keyword=land use change en-keyword=wastewater treatment plant kn-keyword=wastewater treatment plant END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210924 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=多様な菌類および植物パルティティウイルスの分子生物学的・生物学的性状 kn-title=Molecular and biological properties of diverse fungal and plant partitiviruses en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=TELENGECH Paul Kipkemboi en-aut-sei=TELENGECH Paul Kipkemboi en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210924 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=一対の発光ダイオードを光源と検出器に用いた小型光度計の開発とその応用 kn-title=Development of a miniaturized photometer with paired emitter-detector light-emitting diodes and its applications en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= SASIKARN SEETASANG en-aut-sei= SASIKARN SEETASANG en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama university kn-affil=岡山大学大学院自然科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210924 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=胃腺腫:長期間の経過観察中に高率に癌の発生、異時性胃癌発生のリスクを伴う kn-title=Gastric Adenoma: A High Incidence Rate of Developing Carcinoma and Risk of Metachronous Gastric Cancer according to Long-Term Follow-Up en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OkamotoYuki en-aut-sei=Okamoto en-aut-mei=Yuki kn-aut-name=岡本雄貴 kn-aut-sei=岡本 kn-aut-mei=雄貴 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=6 article-no= start-page=691 end-page=697 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=Status of Acute Stroke Practice in Patients with a Cardiac Implantable Electronic Device en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although diagnostic and therapeutic strategies for acute stroke patients in Japan depend largely on magnetic resonance imaging (MRI), patients with cardiac implantable electronic devices (CIED) must still rely on com-puted tomography (CT). We retrospectively analyzed clinical and neuroimaging data of ischemic stroke patients with CIED treated at our hospital. Forty-five patients were enrolled in the study. Patients were divided into two groups according to whether corresponding lesions were detected (group A, n = 21) or not detected (group B, n = 24) by the first brain CT. We also evaluated in detail the clinical courses of patients who arrived at hospital within therapeutic time windows for recanalization therapy. Negative fresh infarct in the first CT was associated, though not significantly, with early onset-to-arrival time and subcortical white matter infarction. Five patients did not undergo recanalization therapy because their families did not agree to the procedure. The reasons for their lack of consent included inadequate information about the safety and efficacy of recanalization therapy because MRI could not be performed. Our study confirmed delayed detection of the corresponding lesion and undertreatment for acute stroke in patients with CIED. en-copyright= kn-copyright= en-aut-name=KatoYuji en-aut-sei=Kato en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayashiTakeshi en-aut-sei=Hayashi en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatoRitsushi en-aut-sei=Kato en-aut-mei=Ritsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UchinoAkira en-aut-sei=Uchino en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakaoMasaki en-aut-sei=Takao en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakahashiShinichi en-aut-sei=Takahashi en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Neurology and Cerebrovascular Medicine, Saitama Medical University International Medical Center kn-affil= affil-num=2 en-affil=Department of Neurology and Cerebrovascular Medicine, Saitama Medical University International Medical Center kn-affil= affil-num=3 en-affil=Department of Cardiology, Saitama Medical University International Medical Center kn-affil= affil-num=4 en-affil=Department of Diagnostic Radiology,Saitama Medical University International Medical Center kn-affil= affil-num=5 en-affil=Department of Neurology and Cerebrovascular Medicine, Saitama Medical University International Medical Center kn-affil= affil-num=6 en-affil=Department of Neurology and Cerebrovascular Medicine, Saitama Medical University International Medical Center kn-affil= en-keyword=stroke kn-keyword=stroke en-keyword=cardiac implantable electronic device kn-keyword=cardiac implantable electronic device en-keyword=computed tomography kn-keyword=computed tomography en-keyword=magnetic resonance imaging kn-keyword=magnetic resonance imaging END start-ver=1.4 cd-journal=joma no-vol=171 cd-vols= no-issue= article-no= start-page=106777 end-page= 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=Portable two-color photometer based on paired light emitter detector diodes and its application to the determination of paraquat and diquat en-subtitle= kn-subtitle= en-abstract= kn-abstract=Here we describe a methodology for the determination of paraquat and diquat using a newly developed portable photometer equipped with two colors of paired light emitter detector diodes (PEDD). The colorimetric measurements employed in this work include the redox reactions between 1) dithiothreitol and diquat to produce the red color characteristic of a diquat radical and 2) between sodium dithionite and either diquat or paraquat that results in the green and blue colors of diquat and paraquat radicals, respectively. The addition of sodium dithionite or dithiothreitol in a solid-state provides reproducible absorbance of the radicals, prevents decomposition of the reagents in a solution, and simplifies handling of the reagents. The diquat radical produced by dithiothreitol (λmax = 495 nm) was successfully detected by using a pair of blue LEDs with a maximum emission wavelength at 472 nm while the radicals of paraquat (λmax = 603 nm) and diquat (λmax = 771 nm) reduced by sodium dithionite were measured by a pair of orange LEDs with a maximum emission wavelength of 609 nm. The proposed method consists of measuring diquat radicals at 472 nm, estimating the absorbance of diquat radicals at 609 nm, and subtracting the estimated absorbance of diquat radicals from the total absorbance at 609 nm to determine paraquat radicals. The developed method yielded examples of excellent linear regression (r2) of more than 0.99 in three calibration curves of the radicals measured at 472 nm for diquat radicals and measured at 609 nm for both diquat and paraquat radicals. The intra-day (n = 3) and inter-day (n = 3) precision of three calibration curves were less than or equal to 5%. By comparison with the standard method of high-performance liquid chromatography, the reliability of the proposed method was proven via the analysis of paraquat and diquat radicals in a commercially available herbicide. en-copyright= kn-copyright= en-aut-name=SeetasangSasikarn en-aut-sei=Seetasang en-aut-mei=Sasikarn kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KanetaTakashi en-aut-sei=Kaneta en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Diquat kn-keyword=Diquat en-keyword=Dithiothreitol kn-keyword=Dithiothreitol en-keyword=Light-emitting diode kn-keyword=Light-emitting diode en-keyword=Paraquat kn-keyword=Paraquat en-keyword=Photometric detector kn-keyword=Photometric detector en-keyword=Sodium dithionite kn-keyword=Sodium dithionite END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=9 article-no= start-page=780 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210906 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between Dental Caries and Influenza Infection in Children: A Japanese Nationwide Population-Based Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Dental caries is the most common chronic childhood disease. Recent studies have suggested that dental caries harbor respiratory infections in adults. We investigated the association between dental caries and influenza in children. In this study, 42,812 children aged 2.5 years, 38,540 children aged 5.5 years, and 34,124 children aged 10 years were included in the analysis from the Longitudinal Survey of Newborns in the 21st Century in Japan, which targeted all children born during a certain period in 2001. We used information on dental caries treated at hospitals and clinics in the past year as exposure and influenza as outcome during the observation periods (1.5-2.5, 4.5-5.5, and 9-10 years of age). We performed a log-binomial regression analysis, adjusting for potential confounders, and stratified analysis according to previous dental caries status. The presence of dental caries increased the incidence of influenza in all three target ages compared with the absence of dental caries. The incidence of influenza increased with the presence of current dental caries, regardless of the presence of past dental caries. These associations were observed irrespective of household income. Early detection and treatment of dental caries may reduce the risk of influenza in children. 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=KadowakiTomoka en-aut-sei=Kadowaki en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 ORCID= affil-num=1 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pediatrics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=dental caries kn-keyword=dental caries en-keyword=influenza kn-keyword=influenza en-keyword=birth cohort kn-keyword=birth cohort en-keyword=oral health kn-keyword=oral health END start-ver=1.4 cd-journal=joma no-vol=72 cd-vols= no-issue=5 article-no= start-page=1841 end-page=1861 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=2016223 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation and design of function for tracing diffusion of classified information for file operations with KVM en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cases of classified information leakage have become increasingly common. To address this problem, we have developed a function for tracing the diffusion of classified information within an operating system. However, this function suffers from the following two problems: first, in order to introduce the function, the operating system's source code must be modified. Second, there is a risk that the function will be disabled when the operating system is attacked. Thus, we have designed a function for tracing the diffusion of classified information in a guest operating system by using a virtual machine monitor. By using a virtual machine monitor, we can introduce the proposed function in various environments without modifying the operating system's source code. In addition, attacks aimed at the proposed function are made more difficult, because the virtual machine monitor is isolated from the operating system. In this paper, we describe the implementation of the proposed function for file operations and child process creation in the guest operating system with a kernel-based virtual machine. Further, we demonstrate the traceability of diffusing classified information by file operations and child process creation. We also report the logical lines of code required to introduce the proposed function and performance overheads. en-copyright= kn-copyright= en-aut-name=FujiiShota en-aut-sei=Fujii en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoMasaya en-aut-sei=Sato en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TaniguchiHideo en-aut-sei=Taniguchi en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil= kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Information Leak Prevention kn-keyword=Information Leak Prevention en-keyword=Virtualization kn-keyword=Virtualization en-keyword=Semantic Gap kn-keyword=Semantic Gap en-keyword=VMM kn-keyword=VMM END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=14 article-no= start-page=7520 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210715 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Novel Radiographic Measurement Method for the Evaluation of Metatarsophalangeal Joint Dislocation of the Lesser Toe in Patients with Rheumatoid Arthritis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Dorsal dislocation of metatarsophalangeal (MTP) joints of the lesser toe frequently occurs in patients with rheumatoid arthritis (RA), and may cause painful and uncomfortable plantar callosities and ulceration. The current study examined the reliability and clinical relevance of a novel radiographic parameter (the MTP overlap distance [MOD]) in evaluating the severity of MTP joint dislocation. The subjects of the current study were 147 RA patients (276 feet; 1104 toes). MOD, defined as the overlap distance of the metatarsal head and the proximal end of the phalanx, was measured on plain radiographs. The relationship between the MOD and clinical complaints (forefoot pain and/or callosity formation) was analyzed to create a severity grading system. As a result, toes with callosities had a significantly larger MOD. ROC analysis revealed that the MOD had a high AUC for predicting an asymptomatic foot (-0.70) and callosities (0.89). MOD grades were defined as follows: grade 1, 0 <= MOD < 5 mm; grade 2, 5 <= MOD < 10 mm; and grade 3, MOD >= 10 mm. The intra- and inter-observer reliability of the MOD grade had high reproducibility. Furthermore, the MOD and MOD grade improved significantly after joint-preserving surgeries for lesser toe deformities. Our results suggest that MOD and MOD grade might be useful tools for the evaluation of deformities of the lesser toe and the effect of surgical intervention for MTP joints in patients with RA. en-copyright= kn-copyright= en-aut-name=OhashiHideki en-aut-sei=Ohashi en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishidaKeiichiro en-aut-sei=Nishida en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NasuYoshihisa en-aut-sei=Nasu en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaigaKenta en-aut-sei=Saiga en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakaharaRyuichi en-aut-sei=Nakahara en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HoritaMasahiro en-aut-sei=Horita en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkitaShunji en-aut-sei=Okita en-aut-mei=Shunji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Takahashi Central Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama City Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=lesser toe kn-keyword=lesser toe en-keyword=metatarsophalangeal joint kn-keyword=metatarsophalangeal joint en-keyword=rheumatoid arthritis kn-keyword=rheumatoid arthritis en-keyword=radiographic measurement kn-keyword=radiographic measurement en-keyword=grading system kn-keyword=grading system END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=11 article-no= start-page=16914 end-page=16926 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210524 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Suppression of the optical crosstalk in a multi-channel silicon photomultiplier array en-subtitle= kn-subtitle= en-abstract= kn-abstract=We propose and study a method of optical crosstalk suppression for silicon photomultipliers (SiPMs) using optical filters.

The proposed technique can be easily applied to suppress the optical crosstalk in SiPMs in cases where filtering near infrared light is compatible with the application. en-copyright= kn-copyright= en-aut-name=MasudaTakahiko en-aut-sei=Masuda en-aut-mei=Takahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AngDaniel G. en-aut-sei=Ang en-aut-mei=Daniel G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HutzlerNicholas R. en-aut-sei=Hutzler en-aut-mei=Nicholas R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MeisenhelderCole en-aut-sei=Meisenhelder en-aut-mei=Cole kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SasaoNoboru en-aut-sei=Sasao en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UetakeSatoshi en-aut-sei=Uetake en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WuXing en-aut-sei=Wu en-aut-mei=Xing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=DeMilleDavid en-aut-sei=DeMille en-aut-mei=David kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=GabrielseGerald en-aut-sei=Gabrielse en-aut-mei=Gerald kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=DoyleJohn M. en-aut-sei=Doyle en-aut-mei=John M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YoshimuraKoji en-aut-sei=Yoshimura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Physics, Harvard University kn-affil= affil-num=3 en-affil=Division of Physics, Mathematics, and Astronomy, California Institute of Technology kn-affil= affil-num=4 en-affil=Department of Physics, Harvard University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=7 en-affil=Department of Physics, Harvard University kn-affil= affil-num=8 en-affil=James Franck Institute and Department of Physics, University of Chicago kn-affil= affil-num=9 en-affil=Center for Fundamental Physics, Northwestern University kn-affil= affil-num=10 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=11 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=2 article-no= start-page=155 end-page=166 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210217 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Transcriptomic analysis of developing seeds in a wheat (Triticum aestivum L.) mutant RSD32 with reduced seed dormancy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Seed dormancy, a major factor regulating pre-harvest sprouting, can severely hinder wheat cultivation. Reduced Seed Dormancy 32 (RSD32), a wheat (Triticum aestivum L.) mutant with reduced seed dormancy, is derived from the pre-harvest sprouting tolerant cultivar, 'Norin61'. RSD32 is regulated by a single recessive gene and mutant phenotype expressed in a seed-specific manner. Gene expressions in embryos of 'Norin61' and RSD32 were compared using RNA sequencing (RNA-seq) analysis at different developmental stages of 20, 30, and 40 days after pollination (DAP). Numbers of up-regulated genes in RSD32 are equivalent in all developmental stages. However, down-regulated genes in RSD32 are more numerous on DAP20 and DAP30 than on DAP40. In central components affecting the circadian clock, homologues to the morning-expressed genes are expressed at lower levels in RSD32. However, higher expressions of homologues acting as evening-expressed genes are observed in RSD32. Homologues of Ca2+ signaling pathway related genes are specifically expressed on DAP20 in 'Norin61'. Lower expression is shown in RSD32. These results suggest that RSD32 mutation expresses on DAP20 and earlier seed developmental stages and suggest that circadian clock regulation and Ca2+ signaling pathway are involved in the regulation of wheat seed dormancy. en-copyright= kn-copyright= en-aut-name=RikiishiKazuhide en-aut-sei=Rikiishi en-aut-mei=Kazuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugimotoManabu en-aut-sei=Sugimoto en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaekawaMasahiko en-aut-sei=Maekawa en-aut-mei=Masahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=mutant kn-keyword=mutant en-keyword=seed development kn-keyword=seed development en-keyword=seed dormancy kn-keyword=seed dormancy en-keyword=transcriptome kn-keyword=transcriptome en-keyword=wheat kn-keyword=wheat END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=琵琶湖における栄養塩循環の季節および鉛直変動過程 kn-title=The process of seasonal and vertical dynamics of nutrient cycle in Lake Biwa en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HUULE TIEN en-aut-sei=HUU en-aut-mei=LE TIEN kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=暑熱環境下におけるウシ子宮内膜細胞の免疫応答変化 kn-title=Alteration of immune responses in bovine endometrial cells under hyperthermia conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=SakaiShunsuke en-aut-sei=Sakai en-aut-mei=Shunsuke kn-aut-name=酒井駿介 kn-aut-sei=酒井 kn-aut-mei=駿介 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=脱カルボニル化および脱カルボキシル化を伴うカルボン酸誘導体の炭素−炭素結合形成反応 kn-title=Carbon-Carbon Bond-Forming Reactions of Carboxylic Acid Derivatives via Decarbonylation and Decarboxylation en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=FuRien en-aut-sei=Fu en-aut-mei=Rien kn-aut-name=符立言 kn-aut-sei=符 kn-aut-mei=立言 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama university kn-affil=岡山大学大学院自然科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=含硫黄多環芳香族炭化水素の合成と半導体特性 kn-title=Synthesis and Semiconducting Properties of Sulfur-Containing Polycyclic Aromatic Hydrocarbons en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=JiJenfei en-aut-sei=Ji en-aut-mei=Jenfei kn-aut-name=吉震飛 kn-aut-sei=吉 kn-aut-mei=震飛 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama university kn-affil=岡山大学大学院自然科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=電子求引性官能基を有するピセンの合成,スペクトル特性およびn-型電界効果型トランジスタへの応用 kn-title=Synthesis and spectral properties of picenes incorporating electron-withdrawing functionalities and their application to n-type field-effect transistors en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=GoaYushin en-aut-sei=Goa en-aut-mei=Yushin kn-aut-name=郭玉?

Gastric adenomas are histologically defined as benign epithelial tumors. While some of them remain adenomas for a long time, others progress to carcinomas. However, long-term outcomes of such cases are not entirely clear. Here, we explored the risk factors and incidence of developing carcinoma from gastric adenoma as well as metachronous gastric cancer.
Methods:
This study was conducted at a facility that adopted a follow-up strategy for gastric adenoma. Lesions histologically diagnosed as gastric intestinal-type adenomas between January 2004 and December 2016 were analyzed. Clinicopathological data were collected from patients’ medical records, and histological changes from adenoma to carcinoma during endoscopic follow-up and risk factors of cancer development were evaluated.
Results:
This study involved 409 lesions from 376 patients. The analysis of the development of gastric cancer from adenoma and metachronous gastric cancer was ultimately performed for 282 lesions from 258 patients and 269 lesions from 246 patients, respectively, due to different follow-up periods. The 5-year rate of carcinoma development was 34.0%. Risk factors for carcinoma development upon multivariate analysis were lesion size ?15 mm and morphological depression. All cases with both factors developed gastric carcinoma, and 50.5% of those with either factor developed carcinoma within 5 years. Gastric adenoma was accompanied by metachronous gastric cancer in 1.5% of the patients annually. The only risk factor for metachronous gastric carcinoma was primary adenoma progressing to carcinoma during the follow-up period.
Discussion/Conclusion:
Given the high rate of carcinoma development in patients with risk factors, resection of gastric adenoma should be considered during the initial examination. Careful observation and follow-up should also be conducted to detect not only changes in the primary adenoma but also the occurrence of metachronous carcinoma, especially in cases of adenoma progressing to carcinoma. en-copyright= kn-copyright= en-aut-name=OkamotoYuki en-aut-sei=Okamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KanzakiHiromitsu en-aut-sei=Kanzaki en-aut-mei=Hiromitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakaeHiroyuki en-aut-sei=Sakae en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AbeMakoto en-aut-sei=Abe en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawaharaYoshiro en-aut-sei=Kawahara en-aut-mei=Yoshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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 Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Practical Gastrointestinal Endoscopy, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=epartment of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=gastric adenoma kn-keyword=gastric adenoma en-keyword=gastric adenoma develop carcinoma kn-keyword=gastric adenoma develop carcinoma en-keyword=metachronous gastric cancer kn-keyword=metachronous gastric cancer en-keyword=long term follow-up kn-keyword=long term follow-up END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e13312 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202153 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Roles of Porphyromonas gulae proteases in bacterial and host cell biology en-subtitle= kn-subtitle= en-abstract= kn-abstract=Porphyromonas gulae, an animal-derived periodontal pathogen, expresses several virulence factors, including fimbria, lipopolysaccharide (LPS) and proteases. We previously reported that its invasive efficiency was dependent on fimbriae types. In addition, P. gulae LPS increased inflammatory responses via toll-like receptors. The present study was conducted to investigate the involvement of P. gulae proteases in bacterial and host cell biology. Porphyromonas gulae strains showed an ability to agglutinate mouse erythrocytes and also demonstrated co-aggregation with Actinomyces viscosus, while the protease inhibitors antipain, PMSF, TLCK and leupeptin diminished P. gulae proteolytic activity, resulting in inhibition of haemagglutination and co-aggregation with A. viscosus. In addition, specific proteinase inhibitors were found to reduce bacterial cell growth. Porphyromonas gulae inhibited Ca9-22 cell proliferation in a multiplicity of infection- and time-dependent manner. Additionally, P. gulae-induced decreases in cell contact and adhesion-related proteins were accompanied by a marked change in cell morphology from well spread to rounded. In contrast, inhibition of protease activity prevented degradation of proteins, such as E-cadherin, beta-catenin and focal adhesion kinase, and also blocked inhibition of cell proliferation. Together, these results indicate suppression of the amount of human proteins, such as gamma-globulin, fibrinogen and fibronectin, by P. gulae proteases, suggesting that a novel protease complex contributes to bacterial virulence. en-copyright= kn-copyright= en-aut-name=UrmiAlam Saki en-aut-sei=Urmi en-aut-mei=Alam Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=InabaHiroaki en-aut-sei=Inaba en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NomuraRyota en-aut-sei=Nomura en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaShoko en-aut-sei=Yoshida en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OharaNaoya en-aut-sei=Ohara en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AsaiFumitoshi en-aut-sei=Asai en-aut-mei=Fumitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakanoKazuhiko en-aut-sei=Nakano en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=Matsumoto‐NakanoMichiyo en-aut-sei=Matsumoto‐Nakano en-aut-mei=Michiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Oral Microbiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and the Advanced Research Center for Oral and Craniofacial Sciences, Dental School, Okayama University kn-affil= affil-num=6 en-affil=Department of Pharmacology, School of Veterinary Medicine Azabu University kn-affil= affil-num=7 en-affil=Department of Pediatric Dentistry, Osaka University Graduate School of Dentistry kn-affil= affil-num=8 en-affil=Department of Pediatric Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=coaggregation kn-keyword=coaggregation en-keyword=haemagglutination kn-keyword=haemagglutination en-keyword=P. gulae kn-keyword=P. gulae en-keyword=protease kn-keyword=protease en-keyword=protein degradation kn-keyword=protein degradation END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=17 end-page=23 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210207 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy of shear wave elastography for evaluating right ventricular myocardial fibrosis in monocrotaline-induced pulmonary hypertension rats en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Right ventricular (RV) function is important for outcomes in pulmonary hypertension. Evaluation of RV myocardial characteristics is useful to assess the disease severity. Shear wave elastography (SWE) provides information of shear wave (SW) elasticity, which is related to tissue hardness, and SW dispersion slope, which reflects tissue viscosity. This study aimed to test the hypothesis that SW elasticity is increased and SW dispersion slope is decreased in the right ventricle of monocrotaline (MCT)-induced pulmonary hypertension rats.

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

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

Conclusions: Higher SW elasticity and lower SW dispersion slope were observed in the fibrotic myocardium of right ventricle in MCT-induced pulmonary hypertension rats. SWE may have the potential to evaluate RV function by assessing myocardial characteristics. en-copyright= kn-copyright= en-aut-name=NakayamaRie en-aut-sei=Nakayama en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakayaYoichi en-aut-sei=Takaya en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KondoMegumi en-aut-sei=Kondo en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobayashiKaoru en-aut-sei=Kobayashi en-aut-mei=Kaoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhnoYuko en-aut-sei=Ohno en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AmiokaNaofumi en-aut-sei=Amioka en-aut-mei=Naofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AkagiSatoshi en-aut-sei=Akagi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YoshidaMasashi en-aut-sei=Yoshida en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Kawasaki University of Medical Welfare kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil= Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Dispersion kn-keyword=Dispersion en-keyword=Elasticity kn-keyword=Elasticity en-keyword=Myocardium kn-keyword=Myocardium en-keyword=Right ventricular function kn-keyword=Right ventricular function en-keyword=Shear wave elastography kn-keyword=Shear wave elastography END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=3 article-no= start-page=1751 end-page=1758 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy of shear wave elastography for assessment of liver function in patients with heart failure en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims
Liver dysfunction is important for prognosis in heart failure (HF). Shear wave elastography (SWE), which is a novel ultrasound technique for charactering tissues, has been used in liver diseases. However, clinical implication of SWE, including dispersion slope, remains unknown in heart diseases. This study aimed to evaluate the efficacy of SWE assessing liver function in the severity of HF.
Methods and results
We enrolled 316 consecutive patients with or suspected heart diseases, who were classified according to the American College of Cardiology Foundation/American Heart Association stage of HF, including 37 with Stage A, 139 with Stage B, 114 with Stage C, and 26 with Stage D, and 45 normal subjects. Elasticity and dispersion slope of shear wave were assessed according to the HF stage. Elasticity and dispersion slope were not elevated in normal subjects and patients with Stage A. Elasticity was slightly increased from Stage A to Stage C and was remarkably elevated in Stage D (normal: 5.2 ± 1.1 kPa, Stage A: 5.4 ± 1.2 kPa, Stage B: 6.4 ± 1.8 kPa, Stage C: 7.8 ± 3.5 kPa, and Stage D: 17.7 ± 12.7 kPa), whereas dispersion slope was gradually increased from Stage A to Stage D (normal: 9.7 ± 1.7m/s/kHz, Stage A: 10.4 ± 1.6m/s/kHz, Stage B: 11.7 ± 2.4m/s/kHz, Stage C: 13.2 ± 3.4m/s/kHz, and Stage D: 17.6 ± 5.6 m/s/kHz). In the early HF stage, dispersion slope was elevated. In the advanced HF stage, both elasticity and dispersion slope were elevated. Liver function test abnormalities were observed only from Stage C or Stage D.
Conclusions
Dispersion slope could detect early liver damage, and the combination of elasticity and dispersion slope could clarify the progression of liver dysfunction in HF. SWE may be valuable to manage therapeutic strategies in patients with HF. en-copyright= kn-copyright= en-aut-name=NakayamaRie en-aut-sei=Nakayama en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakayaYoichi en-aut-sei=Takaya en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TohNorihisa en-aut-sei=Toh en-aut-mei=Norihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= en-keyword=Shear wave elastography kn-keyword=Shear wave elastography en-keyword=Elasticity kn-keyword=Elasticity en-keyword=Dispersion slope kn-keyword=Dispersion slope en-keyword=Liver dysfunction kn-keyword=Liver dysfunction en-keyword=Heart failure kn-keyword=Heart failure END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page=17 end-page=27 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2020年 環境デザイン工学科 学術論文等 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=1 article-no= start-page=4277 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021219 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Direct evidence of electronic ferroelectricity in YbFe2O4 using neutron diffraction and nonlinear spectroscopy en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report the first observation of room temperature spontaneous electric polarization in an electronic ferroelectric material, a YbFe2O4 single crystal. The observation was based on second harmonic generation (SHG), a nonlinear optical process. Tensor analysis of the SHG signal revealed that this material has a polar charge superstructure with Cm symmetry. This result settles the long-term discussion on the uncertainty about electronic ferroelectric properties, including the charge order structure. We present a complete picture of the polar charge ordering of this material via consistent results from two different characterization methods. The SHG signal shows the same temperature dependence as the superlattice signal observed in neutron diffraction experiments. These results prove ferroelectric coupling to electron ordering in YbFe2O4, which results in electronic ferroelectricity which is enabled by the real space ordering of iron cations with different valences. The existence of electronic ferroelectricity holds promise for future electronics technologies where devices run a thousand times faster than frequency of the present CPU (a few gigahertz) embedded in smartphones, etc. en-copyright= kn-copyright= en-aut-name=FujiwaraK. en-aut-sei=Fujiwara en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukadaY. en-aut-sei=Fukada en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkudaY. en-aut-sei=Okuda en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SeimiyaR. en-aut-sei=Seimiya en-aut-mei=R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IkedaN. en-aut-sei=Ikeda en-aut-mei=N. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YokoyamaK. en-aut-sei=Yokoyama en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YuH. en-aut-sei=Yu en-aut-mei=H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KoshiharaS. en-aut-sei=Koshihara en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkimotoY. en-aut-sei=Okimoto en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Department of Chemistry, Tokyo Institute of Technology kn-affil= affil-num=7 en-affil=Department of Chemistry, Tokyo Institute of Technology kn-affil= affil-num=8 en-affil=Department of Chemistry, Tokyo Institute of Technology kn-affil= affil-num=9 en-affil=Department of Chemistry, Tokyo Institute of Technology kn-affil= END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=1 article-no= start-page=55 end-page=61 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202102 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Thoracoscopic Localization of Small Peripheral Pulmonary Lesions Using Percutaneous Computed Tomography-guided Pleural Dye Marking: A Retrospective Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Small pulmonary lesions are often difficult to localize during thoracoscopic surgery. We describe a new com-puted tomography (CT)-guided pleural dye-marking method for small peripheral pulmonary lesions that does not involve a visceral pleural puncture. We used this technique for 23 lesions (22 patients) who underwent tho-racoscopic partial lung resection (Nov. 2016-Jan. 2018). With the patient in the lateral decubitus position, pre-operative CT-guided marking on the skin over the lesion was performed. During the surgery, we marked the visceral pleura with a skin marker directly or with an infant-size nutrition catheter with crystal violet at the tip through a venous indwelling needle inserted perpendicular to the skin marking. We localized and resected the lesions in all cases, without complications. The median nodule size measured histopathologically was 8 (4-20) mm overall, and 7 (0-20) mm of the solid part; the median distance from the visceral pleura to the nodule was 9 (1-33) mm. The median operation time was 67 (37-180) min. The median postoperative hospital stay was 3 (3-11) days. Our CT-guided pleural dye-marking method is useful and safe for the localization of small periph-eral pulmonary lesions in thoracoscopic partial lung resections. en-copyright= kn-copyright= en-aut-name=KuboYujiro en-aut-sei=Kubo en-aut-mei=Yujiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WatanabeMototsugu en-aut-sei=Watanabe en-aut-mei=Mototsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ChoshiHaruki en-aut-sei=Choshi en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsubaraKei en-aut-sei=Matsubara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShiotaniToshio en-aut-sei=Shiotani en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KataokaKazuhiko en-aut-sei=Kataoka en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Thoracic Surgery, Iwakuni Clinical Center kn-affil= affil-num=2 en-affil=Department of Thoracic Surgery, Iwakuni Clinical Center kn-affil= affil-num=3 en-affil=Department of Thoracic Surgery, Iwakuni Clinical Center kn-affil= affil-num=4 en-affil=Department of Thoracic Surgery, Iwakuni Clinical Center kn-affil= affil-num=5 en-affil=Department of Thoracic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Thoracic Surgery, Iwakuni Clinical Center kn-affil= en-keyword=Small pulmonary lesion kn-keyword=Small pulmonary lesion en-keyword=ground glass nodule kn-keyword=ground glass nodule en-keyword=marking kn-keyword=marking en-keyword=localization kn-keyword=localization en-keyword=thoracocentesis kn-keyword=thoracocentesis END start-ver=1.4 cd-journal=joma no-vol=95 cd-vols= no-issue=4 article-no= start-page=1241 end-page=1250 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210116 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Spatiotemporal analysis of the UPR transition induced by methylmercury in the mouse brain en-subtitle= kn-subtitle= en-abstract= kn-abstract=Methylmercury (MeHg), an environmental toxicant, induces neuronal cell death and injures a specific area of the brain. MeHg-mediated neurotoxicity is believed to be caused by oxidative stress and endoplasmic reticulum (ER) stress but the mechanism by which those stresses lead to neuronal loss is unclear. Here, by utilizing the ER stress-activated indicator (ERAI) system, we investigated the signaling alterations in the unfolded protein response (UPR) prior to neuronal apoptosis in the mouse brain. In ERAI transgenic mice exposed to MeHg (25 mg/kg, S.C.), the ERAI signal, which indicates activation of the cytoprotective pathway of the UPR, was detected in the brain. Interestingly, detailed ex vivo analysis showed that the ERAI signal was localized predominantly in neurons. Time course analysis of MeHg exposure (30 ppm in drinking water) showed that whereas the ERAI signal was gradually attenuated at the late phase after increasing at the early phase, activation of the apoptotic pathway of the UPR was enhanced in proportion to the exposure time. These results suggest that MeHg induces not only ER stress but also neuronal cell death via a UPR shift. UPR modulation could be a therapeutic target for treating neuropathy caused by electrophiles similar to MeHg. en-copyright= kn-copyright= en-aut-name=HiraokaHideki en-aut-sei=Hiraoka en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NomuraRyosuke en-aut-sei=Nomura en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakasugiNobumasa en-aut-sei=Takasugi en-aut-mei=Nobumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AkaiRyoko en-aut-sei=Akai en-aut-mei=Ryoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwawakiTakao en-aut-sei=Iwawaki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KumagaiYoshito en-aut-sei=Kumagai en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujimuraMasatake en-aut-sei=Fujimura en-aut-mei=Masatake kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UeharaTakashi en-aut-sei=Uehara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Division of Cell Medicine, Department of Life Science, Medical Research Institute, Kanazawa Medical University kn-affil= affil-num=5 en-affil=Division of Cell Medicine, Department of Life Science, Medical Research Institute, Kanazawa Medical University kn-affil= affil-num=6 en-affil=Environmental Biology Laboratory, Faculty of Medicine, University of Tsukuba kn-affil= affil-num=7 en-affil=Department of Basic Medical Science, National Institute for Minamata Disease kn-affil= affil-num=8 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Methylmercury kn-keyword=Methylmercury en-keyword=Neuronal cell death kn-keyword=Neuronal cell death en-keyword=ER stress kn-keyword=ER stress en-keyword=UPR kn-keyword=UPR en-keyword=ERAI gene kn-keyword=ERAI gene END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=5 article-no= start-page=643 end-page=649 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Crizotinib for recurring non-small-cell lung cancer with EML4-ALK fusion genes previously treated with alectinib: A phase II trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
The efficacy of crizotinib treatment for recurring EML4‐ALK‐positive non‐small cell lung cancer (NSCLC) previously treated with alectinib is unclear. Based on our preclinical findings regarding hepatocyte growth factor/mesenchymal epithelial transition (MET) pathway activation as a potential mechanism of acquired resistance to alectinib, we conducted a phase II trial of the anaplastic lymphoma kinase/MET inhibitor, crizotinib, in patients with alectinib‐refractory, EML4‐ALK‐positive NSCLC.
Methods
Patients with ALK‐rearranged tumors treated with alectinib immediately before enrolling in the trial received crizotinib monotherapy. The objective response rate was the primary outcome of interest.
Results
Nine (100%) patients achieved a partial response with alectinib therapy with a median treatment duration of 6.7 months. Crizotinib was administered with a median treatment interval of 50 (range, 20?433) days. The overall response rate was 33.3% (90% confidence interval [CI]: 9.8?65.5 and 95% CI: 7.5?70.1), which did not reach the predefined criteria of 50%. Two (22%) patients who achieved a partial response had brain metastases at baseline. Progression‐free survival (median, 2.2 months) was not affected by the duration of treatment with alectinib. The median survival time was 24.1 months. The most common adverse events were an increased aspartate transaminase/alanine transaminase (AST/ALT) ratio (44%) and appetite loss (33%); one patient developed transient grade 4 AST/ALT elevation, resulting in treatment discontinuation. Other adverse events were consistent with those previously reported; no treatment‐related deaths occurred.
Conclusions
Although the desired response rate was not achieved, crizotinib monotherapy following treatment with alectinib showed efficacy alongside previously described adverse events. en-copyright= kn-copyright= en-aut-name=HaradaDaijiro en-aut-sei=Harada en-aut-mei=Daijiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IsozakiHideko en-aut-sei=Isozaki en-aut-mei=Hideko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KozukiToshiyuki en-aut-sei=Kozuki en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YokoyamaToshihide en-aut-sei=Yokoyama en-aut-mei=Toshihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshiokaHiroshige en-aut-sei=Yoshioka en-aut-mei=Hiroshige kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=BesshoAkihiro en-aut-sei=Bessho en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HosokawaShinobu en-aut-sei=Hosokawa en-aut-mei=Shinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakataIchiro en-aut-sei=Takata en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakigawaNagio en-aut-sei=Takigawa en-aut-mei=Nagio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HottaKatsuyuki en-aut-sei=Hotta en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KiuraKatsuyuki en-aut-sei=Kiura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=Okayama Lung Cancer Study Group en-aut-sei=Okayama Lung Cancer Study Group en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Thoracic Oncology, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=2 en-affil=Department of Clinical Pharmaceutics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Thoracic Oncology, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=4 en-affil=Department of Respiratory Medicine, Kurashiki Central Hospital kn-affil= affil-num=5 en-affil=Department of Respiratory Medicine, Kurashiki Central Hospital kn-affil= affil-num=6 en-affil=Department of Respiratory Medicine, Japanese Red Cross Okayama Hospital kn-affil= affil-num=7 en-affil=Department of Respiratory Medicine, Japanese Red Cross Okayama Hospital kn-affil= affil-num=8 en-affil=Department of Internal Medicine, Fukuyama City Hospital kn-affil= affil-num=9 en-affil= kn-affil= affil-num=10 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=12 en-affil= kn-affil= en-keyword=Alectinib kn-keyword=Alectinib en-keyword=anaplastic lymphoma kinase kn-keyword=anaplastic lymphoma kinase en-keyword=crizotinib kn-keyword=crizotinib en-keyword=drug therapy kn-keyword=drug therapy en-keyword=non-small cell lung carcinoma kn-keyword=non-small cell lung carcinoma END start-ver=1.4 cd-journal=joma no-vol=110 cd-vols= no-issue= article-no= start-page=15 end-page=31 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The List of Published by Members of the Faculty From January to December 2020. kn-title=公表学術論文等リスト 2020 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=1 article-no= start-page=28 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210113 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness, safety, and factors associated with the clinical success of endoscopic biliary drainage for patients with hepatocellular carcinoma: a retrospective multicenter study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Only a few reports have assessed the effectiveness of endoscopic biliary drainage (EBD) in hepatocellular carcinoma (HCC) patients with obstructive jaundice and liver dysfunction.
Methods
This was a retrospective study based on the clinical databases from the Okayama University Hospital and 10 affiliated hospitals. All patients received EBD for jaundice or liver dysfunction. The indication for EBD was aggravation of jaundice or liver dysfunction with intrahepatic bile duct (IHBD) dilation. The technical and clinical success rate, complications, factors associated with clinical failure, and survival duration were evaluated.
Results
A total of 107 patients were enrolled in this study. Technical success was achieved in 105 of 107 patients (98.1%). Clinical success was achieved in 85 of 105 patients (81%). Complications related to endoscopic retrograde cholangiography (ERC) occurred in 3 (2.8%) patients. Child?Pugh class C (odds ratio 3.90, 95% confidence interval [CI] 1.47?10.4, p?=?0.0046) was the only factor associated with clinical failure, irrespective of successful drainage. The median survival duration was significantly longer in patients with clinical success than in those without clinical success (5.0 months vs. 0.93 months; hazard ratio [HR] 3.2, 95% CI 1.87?5.37). HCC Stage I/II/III (HR 0.57, CI 0.34?0.95, p?=?0.032), absence of portal thrombosis (HR 0.52, CI 0.32?0.85, p?=?0.0099), and clinical success (HR 0.39, CI 0.21?0.70, p?=?0.0018) were significant factors associated with a long survival.
Conclusions
EBD for obstructive jaundice and liver dysfunction in patients with HCC can be performed safely with a high technical success rate. Clinical success can improve the survival duration, even in patients expected to have a poor prognosis. en-copyright= kn-copyright= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatoHironari en-aut-sei=Kato en-aut-mei=Hironari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UekiToru en-aut-sei=Ueki en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshidaEtsuji en-aut-sei=Ishida en-aut-mei=Etsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakataniMasahiro en-aut-sei=Takatani en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiiMasakuni en-aut-sei=Fujii en-aut-mei=Masakuni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WatoMasaki en-aut-sei=Wato en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ToyokawaTatsuya en-aut-sei=Toyokawa en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HaradaRyo en-aut-sei=Harada en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TsugenoHirofumi en-aut-sei=Tsugeno en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MatsubaraMinoru en-aut-sei=Matsubara en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MatsushitaHiroshi en-aut-sei=Matsushita en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University 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 Internal Medicine, Fukuyama City Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Kurashiki Central Hospital kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=6 en-affil=Department of Internal Medicine, Okayama Saiseikai General Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology, Kagawa Prefectural Central Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology, National Hospital Organization Fukuyama Medical Center kn-affil= affil-num=9 en-affil=Department of Gastroenterology, Japanese Red Cross Okayama Hospital kn-affil= affil-num=10 en-affil=Department of Internal Medicine, Tsuyama Central Hospital kn-affil= affil-num=11 en-affil=Department of Internal Medicine, Sumitomo Besshi Hospital kn-affil= affil-num=12 en-affil=Department of Gastroenterology, Okayama City Hospital kn-affil= affil-num=13 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Endoscopic retrograde cholangiopancreatography kn-keyword=Endoscopic retrograde cholangiopancreatography en-keyword=Jaundice kn-keyword=Jaundice en-keyword=Hepatocellular carcinoma kn-keyword=Hepatocellular carcinoma en-keyword=Liver dysfunction kn-keyword=Liver dysfunction END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201028 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Nickel-Catalyzed Decarbonylative Alkynylation of Acyl Fluorides with Terminal Alkynes under Copper-Free Conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nickel-catalyzed decarbonylative alkynylation of acyl fluorides with terminal silylethynes under copper-free conditions is described.

To eliminate the bacteria, bovine endometrial cells secrete chemokines, such as IL-6 and MCP1, which attract macrophages (M Phi s) to the subepithelial stroma. These attracted M Phi s are not only involved in bacterial elimination but also the orchestration of inflammation and tissue repair. These immune responses aid in the recovery from endometritis; however, the recovery from endometritis takes longer in summer than in any other season. Based on these findings, we hypothesized that heat stress (HS) affects the chemokine production in endometrial cells. To confirm this hypothesis, we compared IL-6 and MCP1 production induced by lipopolysaccharide (LPS) in bovine endometrial epithelial and stromal cells under normal (38.5 degrees C) and HS conditions (40.5 degrees C). In the endometrial epithelial cells, IL-6 production stimulated by LPS was significantly (p < .05) suppressed under HS conditions. MCP1 production in endometrial epithelial cells was not detected under both the control and HS conditions regardless of the presence of LPS. Moreover, LPS significantly (p < .05) stimulated IL-6 and MCP1 production in endometrial stromal cells. Moreover, HS significantly (p < .05) enhanced their production compared to that under the control conditions. In addition, HS did not affect the migration ability of M Phi s; however, the supernatant of the endometrial stromal cells cultured under the HS condition significantly (p < .05) attracted the M Phi s when compared to the control condition. These results suggest that HS disrupts chemokine production in two types of endometrial cells and alters the distribution of M Phi s in the endometrium during the summer. en-copyright= kn-copyright= en-aut-name=SakaiShunsuke en-aut-sei=Sakai en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HatabuToshimitsu en-aut-sei=Hatabu en-aut-mei=Toshimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamamotoYuki en-aut-sei=Yamamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KimuraKoji en-aut-sei=Kimura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=chemokine kn-keyword=chemokine en-keyword=cow kn-keyword=cow en-keyword=endometrial cells kn-keyword=endometrial cells en-keyword=endometritis kn-keyword=endometritis en-keyword=heat stress kn-keyword=heat stress END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=6 article-no= start-page=557 end-page=562 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=A Japanese Patient with Gastric Cancer and Dihydropyrimidine Dehydrogenase Deficiency Presenting with DPYD Variants en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 63-year-old Japanese male with stomach adenocarcinoma received oral 5-fluorouracil derivative, cisplatin and trastuzumab chemotherapy. On day 8, severe diarrhea and mucositis developed; chemotherapy was stopped. On day 14, the patient developed renal dysfunction and febrile neutropenia. He also suffered from pneumonia due to Candida albicans. Systemic symptoms improved after intensive conservative treatment. Best supportive care was continued until the patient died from gastric cancer. The dihydropyrimidine dehydroge-nase protein level was low at 3.18 U/mg protein. The result of DPYD genotyping revealed three variants at posi-tions 1615 (G > A), 1627 (A > G), and 1896 (T > C) in exons 13, 13, and 14, respectively. en-copyright= kn-copyright= en-aut-name=IshiguroMikako en-aut-sei=Ishiguro en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakenakaRyuta en-aut-sei=Takenaka en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OguraKenichiro en-aut-sei=Ogura en-aut-mei=Kenichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiratsukaAkira en-aut-sei=Hiratsuka en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakedaHiromasa en-aut-sei=Takeda en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KawaiDaisuke en-aut-sei=Kawai en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsugenoHirofumi en-aut-sei=Tsugeno en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujikiShigeatsu en-aut-sei=Fujiki en-aut-mei=Shigeatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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 Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=2 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=3 en-affil=Department of Drug Metabolism and Molecular Toxicology, School of Pharmacy, Tokyo University of Pharmacy and Life Sciences kn-affil= affil-num=4 en-affil=Department of Drug Metabolism and Molecular Toxicology, School of Pharmacy, Tokyo University of Pharmacy and Life Sciences kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=6 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=7 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=8 en-affil=Department of Internal Medicine, Tsuyama Chuo 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= en-keyword=5-fluorouracil kn-keyword=5-fluorouracil en-keyword=dihydropyrimidine dehydrogenase deficiency kn-keyword=dihydropyrimidine dehydrogenase deficiency en-keyword=DPYD variant kn-keyword=DPYD variant en-keyword=gastric cancer kn-keyword=gastric cancer END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=11 article-no= start-page=1534 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Deep Learning for Osteoporosis Classification Using Hip Radiographs and Patient Clinical Covariates en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study considers the use of deep learning to diagnose osteoporosis from hip radiographs, and whether adding clinical data improves diagnostic performance over the image mode alone. For objective labeling, we collected a dataset containing 1131 images from patients who underwent both skeletal bone mineral density measurement and hip radiography at a single general hospital between 2014 and 2019. Osteoporosis was assessed from the hip radiographs using five convolutional neural network (CNN) models. We also investigated ensemble models with clinical covariates added to each CNN. The accuracy, precision, recall, specificity, negative predictive value (npv), F1 score, and area under the curve (AUC) score were calculated for each network. In the evaluation of the five CNN models using only hip radiographs, GoogleNet and EfficientNet b3 exhibited the best accuracy, precision, and specificity. Among the five ensemble models, EfficientNet b3 exhibited the best accuracy, recall, npv, F1 score, and AUC score when patient variables were included. The CNN models diagnosed osteoporosis from hip radiographs with high accuracy, and their performance improved further with the addition of clinical covariates from patient records. en-copyright= kn-copyright= en-aut-name=YamamotoNorio en-aut-sei=Yamamoto en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SukegawaShintaro en-aut-sei=Sukegawa en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KitamuraAkira en-aut-sei=Kitamura en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GotoRyosuke en-aut-sei=Goto en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=NakanoKeisuke en-aut-sei=Nakano en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakabatakeKiyofumi en-aut-sei=Takabatake en-aut-mei=Kiyofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawaiHotaka en-aut-sei=Kawai en-aut-mei=Hotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NagatsukaHitoshi en-aut-sei=Nagatsuka en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KawasakiKeisuke en-aut-sei=Kawasaki en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FurukiYoshihiko en-aut-sei=Furuki en-aut-mei=Yoshihiko 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, Kagawa Prefectural Central Hospital kn-affil= affil-num=2 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Search Space Inc. kn-affil= affil-num=4 en-affil=Search Space Inc. kn-affil= affil-num=5 en-affil=Department of Musculoskeletal Traumatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=11 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa Prefectural Central Hospital 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=osteoporosis kn-keyword=osteoporosis en-keyword=deep learning kn-keyword=deep learning en-keyword=hip radiograph kn-keyword=hip radiograph en-keyword=ensemble model kn-keyword=ensemble model END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=イネの亜鉛吸収に関する生理学的及び分子生物学的解析 kn-title=Physiological and Molecular Characterization of Zinc Uptake in Rice en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HuangSheng en-aut-sei=Huang en-aut-mei=Sheng kn-aut-name=黄勝 kn-aut-sei=黄 kn-aut-mei=勝 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 END start-ver=1.4 cd-journal=joma no-vol=63 cd-vols= no-issue=1 article-no= start-page=175 end-page=182 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=On some families of invariant polynomials divisible by three and their zeta functions en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this note, we establish an analog of the Mallows-Sloane bound for Type III formal weight enumerators.

We also discuss some properties of the zeta functions for such polynomials. en-copyright= kn-copyright= en-aut-name=ChinenKoji en-aut-sei=Chinen en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Mathematics, School of Science and Engineering, Kindai University kn-affil= en-keyword=Binomial moment kn-keyword=Binomial moment en-keyword=Divisible code kn-keyword=Divisible code en-keyword=Invariant polynomial ring kn-keyword=Invariant polynomial ring en-keyword=Zeta function for codes kn-keyword=Zeta function for codes en-keyword=Riemann hypothesis kn-keyword=Riemann hypothesis END start-ver=1.4 cd-journal=joma no-vol=E98D cd-vols= no-issue=4 article-no= start-page=807 end-page=811 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=2015 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Access Control to Prevent Malicious JavaScript Code Exploiting Vulnerabilities of WebView in Android OS en-subtitle= kn-subtitle= en-abstract= kn-abstract=Android applications that using WebView can load and display web pages.

This paper proposes DroidTrack, a method for tracking the diffusion of personal information and preventing its leakage on an Android device. DroidTrack alerts the user of the possibility of information leakage when an app uses APIs to communicate with outside. These alerts are triggered only if the app has already called APIs to collect personal information. Users are given the option to refuse the execution of the API if it is not appropriate. Further, by illustrating how their personal data is diffused, users can have the necessary information to help them decide whether the API use is appropriate. en-copyright= kn-copyright= en-aut-name=SakamotoSyunya en-aut-sei=Sakamoto en-aut-mei=Syunya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Android kn-keyword=Android en-keyword=Malware kn-keyword=Malware en-keyword=Preventing information leakage kn-keyword=Preventing information leakage en-keyword=API control kn-keyword=API control END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=16 article-no= start-page=4778 end-page=4796 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Low temperature modulates natural peel degreening in lemon fruit independently of endogenous ethylene en-subtitle= kn-subtitle= en-abstract= kn-abstract=Peel degreening is an important aspect of fruit ripening in many citrus fruit, and previous studies have shown that it can be advanced by ethylene treatment or by low-temperature storage. However, the important regulators and pathways involved in natural peel degreening remain largely unknown. To determine how natural peel degreening is regulated in lemon fruit (Citrus limon), we studied transcriptome and physiochemical changes in the flavedo in response to ethylene treatment and low temperatures. Treatment with ethylene induced rapid peel degreening, which was strongly inhibited by the ethylene antagonist, 1-methylcyclopropene (1-MCP). Compared with 25 degrees C, moderately low storage temperatures of 5-20 degrees C also triggered peel degreening. Surprisingly, repeated 1-MCP treatments failed to inhibit the peel degreening induced by low temperature. Transcriptome analysis revealed that low temperature and ethylene independently regulated genes associated with chlorophyll degradation, carotenoid metabolism, photosystem proteins, phytohormone biosynthesis and signalling, and transcription factors. Peel degreening of fruit on trees occurred in association with drops in ambient temperature, and it coincided with the differential expression of low temperature-regulated genes. In contrast, genes that were uniquely regulated by ethylene showed no significant expression changes during on-tree peel degreening. Based on these findings, we hypothesize that low temperature plays a prominent role in regulating natural peel degreening independently of ethylene in citrus fruit. en-copyright= kn-copyright= en-aut-name=MitaloOscar W. en-aut-sei=Mitalo en-aut-mei=Oscar W. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtsukiTakumi en-aut-sei=Otsuki en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkadaRui en-aut-sei=Okada en-aut-mei=Rui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ObitsuSaeka en-aut-sei=Obitsu en-aut-mei=Saeka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasudaKanae en-aut-sei=Masuda en-aut-mei=Kanae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HojoYuko en-aut-sei=Hojo en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuuraTakakazu en-aut-sei=Matsuura en-aut-mei=Takakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MoriIzumi C. en-aut-sei=Mori en-aut-mei=Izumi C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AbeDaigo en-aut-sei=Abe en-aut-mei=Daigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AsicheWilliam O. en-aut-sei=Asiche en-aut-mei=William O. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AkagiTakashi en-aut-sei=Akagi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KuboYasutaka en-aut-sei=Kubo en-aut-mei=Yasutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=UshijimaKoichiro en-aut-sei=Ushijima en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=8 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=9 en-affil=National Agriculture and Food Research Organization, Shikoku Research Station kn-affil= affil-num=10 en-affil=Department of Research and Development, Del Monte Kenya Ltd kn-affil= affil-num=11 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=12 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=13 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=1-methylcyclopropene kn-keyword=1-methylcyclopropene en-keyword=carotenoids kn-keyword=carotenoids en-keyword=chlorophyll kn-keyword=chlorophyll en-keyword=Citrus limon kn-keyword=Citrus limon en-keyword=ethylene kn-keyword=ethylene en-keyword=low temperature kn-keyword=low temperature en-keyword=peel degreening kn-keyword=peel degreening en-keyword=phytohormones kn-keyword=phytohormones en-keyword=transcriptome kn-keyword=transcriptome END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=17 article-no= start-page=3842 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200824 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis and Physicochemical Properties of 2,7-Disubstituted Phenanthro[2,1-b:7,8-b']dithiophenes en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report the design, synthesis, and physicochemical properties of an array of phenanthro[2,1-b:7,8-b']dithiophene (PDT-2) derivatives by introducing five types of alkyl (CnH2n+1; n = 8, 10, 12, 13, and 14) or two types of decylthienyl groups at 2,7-positions of the PDT-2 core. Systematic investigation revealed that the alkyl length and the type of side chains have a great effect on the physicochemical properties. For alkylated PDT-2, the solubility was gradually decreased as the chain length was increased. For instance, C-8-PDT-2 exhibited the highest solubility (5.0 g/L) in chloroform. Additionally, substitution with 5-decylthienyl groups showed poor solubility in both chloroform and toluene, whereas PDT-2 with 4-decylthienyl groups resulted in higher solubility. Furthermore, UV-vis absorption of PDT-2 derivatives substituted by decylthienyl groups showed a redshift, indicating the extension of their pi-conjugation length. This work reveals that modification of the conjugated core by alkyl or decylthienyl side chains may be an efficient strategy by which to change the physicochemical properties, which might lead to the development of high-performance organic semiconductors. en-copyright= kn-copyright= en-aut-name=JiZhenfei en-aut-sei=Ji en-aut-mei=Zhenfei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ChengZeliang en-aut-sei=Cheng en-aut-mei=Zeliang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoriHiroki en-aut-sei=Mori en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishiharaYasushi en-aut-sei=Nishihara en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=phenacene-type compounds kn-keyword=phenacene-type compounds en-keyword=thiophene ring kn-keyword=thiophene ring en-keyword=cross-coupling kn-keyword=cross-coupling en-keyword=alkyl side chains kn-keyword=alkyl side chains en-keyword=UV-vis absorption kn-keyword=UV-vis absorption en-keyword=p-type organic semiconductors kn-keyword=p-type organic semiconductors en-keyword=organic field-effect transistor (OFET) kn-keyword=organic field-effect transistor (OFET) END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue= article-no= start-page=168 end-page=171 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=2020 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Laparoscopic liver resection of segment seven: A case report and review of surgical techniques en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction
Laparoscopic liver resection of segment seven (LLR-S7) is a technically challenging procedure due to its anatomical location and difficult accessibility. Herein, we present our experience with LLR-S7, and demonstrate a literature review regarding surgical techniques.
Presentation of case
A 28-year-old female was diagnosed with rectosigmoid cancer and synchronous liver metastases at the segment three (S3) and S7, which were treated with laparoscopic procedure. After the completely mobilization of the right lobe, the Glissonean pedicle of S7 (G7) was intrahepatically transected. The right hepatic vein was exposed to identify the venous branch of S7 (V7). Finally the liver parenchyma between RHV and dissection line was divided.
Discussion
Various laparoscopic approaches for S7 have been reported including the Glissonian approach from the hilum, the intrahepatic Glissonean approach, the caudate lobe first approach, and the lateral approach from intercostal ports. To perform LLR-S7 safely, it is important to understand the advantage of each technique including the trocar placement and approaches to S7 by laparoscopy.
Conclusion
We present our experience of LLR-S7 for the tumor located at the top of S7, successfully performed with the intrahepatic Glissonean approach. LLR-S7 can be performed safely with advanced laparoscopic techniques and sufficient knowledge on various approaches for S7. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuiseTakashi en-aut-sei=Kuise en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UmedaYuzo en-aut-sei=Umeda en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaRyuichi en-aut-sei=Yoshida en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=YagiTakahito en-aut-sei=Yagi en-aut-mei=Takahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Laparoscopic kn-keyword=Laparoscopic en-keyword=Liver kn-keyword=Liver en-keyword=Segment seven kn-keyword=Segment seven END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=6 article-no= start-page=1576 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200528 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Oxidative Stress Management in Chronic Liver Diseases and Hepatocellular Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chronic viral hepatitis B and C and non-alcoholic fatty liver disease (NAFLD) have been widely acknowledged to be the leading causes of liver cirrhosis and hepatocellular carcinoma. As anti-viral treatment progresses, the impact of NAFLD is increasing. NAFLD can coexist with chronic viral hepatitis and exacerbate its progression. Oxidative stress has been recognized as a chronic liver disease progression-related and cancer-initiating stress response. However, there are still many unresolved issues concerning oxidative stress, such as the correlation between the natural history of the disease and promising treatment protocols. Recent findings indicate that oxidative stress is also an anti-cancer response that is necessary to kill cancer cells. Oxidative stress might therefore be a cancer-initiating response that should be down regulated in the pre-cancerous stage in patients with risk factors for cancer, while it is an anti-cancer cell response that should not be down regulated in the post-cancerous stage, especially in patients using anti-cancer agents. Antioxidant nutrients should be administered carefully according to the patients' disease status. In this review, we will highlight these paradoxical effects of oxidative stress in chronic liver diseases, pre- and post-carcinogenesis. en-copyright= kn-copyright= en-aut-name=UchidaDaisuke en-aut-sei=Uchida en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 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=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=OnishiHideki en-aut-sei=Onishi en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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= en-keyword=oxidative stress kn-keyword=oxidative stress en-keyword=chronic hepatitis kn-keyword=chronic hepatitis en-keyword=hepatocellular carcinoma kn-keyword=hepatocellular carcinoma END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=3 article-no= start-page=83 end-page=92 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200421 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Early Decline of alpha-Fetoprotein and Des-gamma-Carboxy Prothrombin Predicts the Response of Hepatic Arterial Infusion Chemotherapy in Hepatocellular Carcinoma Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Molecular targeting drugs are recommended as second-line treatment for intrahepatic advanced hepatocellular carcinoma (HCC). However, in Asia, hepatic arterial infusion chemotherapy (HAIC) is also considered as a second-line treatment because it improves the survival of responders. The aim of this study was to predict responders and non-responders to HAIC with low-dose cisplatin plus 5-fluorouracil (LFP) using tumor markers.
Objective and Methods: The data of 47 patients who received LFP for the first time in our hospital were analyzed retrospectively. We evaluated the association between treatment response by Response Evaluation Criteria in Solid Tumors and the changing ratio of the serum concentration of alpha-fetoprotein (AFP),Lens culinarisagglutinin-reactive fraction of AFP (AFP-L3), and des-gamma-carboxy prothrombin (DCP) 2 weeks after LFP initiation.
Results: The number of patients showing a complete response (CR), a partial response (PR), stable disease (SD), and progressive disease (PD) was 0 (0%), 20 (43%), 18 (38%), and 9 (19%), respectively. The AFP ratio showed significant positive correlations for PR vs. SD (p= 0.004) and PR vs. PD (p= 0.003). The DCP ratio correlated significantly for PR vs. SD (p= 0.02). The optimal cutoff values for responders were 0.79 for the AFP ratio and 0.53 for the DCP ratio. Prediction using both or either cutoff value showed 93% sensitivity, 53% specificity, a 94% negative predictive value, and a 57% positive predictive value.
Conclusion: Optimal cutoff values for AFP and DCP ratios enable prediction of nonresponders to HAIC with LFP. This simple and early assessment method allows the use of HAIC and molecular targeting drugs for HCC treatment. en-copyright= kn-copyright= en-aut-name=YamamotoShumpei en-aut-sei=Yamamoto en-aut-mei=Shumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OnishiHideki en-aut-sei=Onishi en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakakiAkinobu en-aut-sei=Takaki en-aut-mei=Akinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OyamaAtsushi en-aut-sei=Oyama en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AdachiTakuya en-aut-sei=Adachi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WadaNozomu en-aut-sei=Wada en-aut-mei=Nozomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakataMasahiro en-aut-sei=Sakata en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YasunakaTetsuya en-aut-sei=Yasunaka en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShirahaHidenori en-aut-sei=Shiraha en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Hepatocellular carcinoma kn-keyword=Hepatocellular carcinoma en-keyword=Hepatic arterial infusion chemotherapy kn-keyword=Hepatic arterial infusion chemotherapy en-keyword=Low-dose cisplatin plus 5-fluorouracil kn-keyword=Low-dose cisplatin plus 5-fluorouracil en-keyword=alpha-Fetoprotein kn-keyword=alpha-Fetoprotein en-keyword=Des-gamma-carboxy prothrombin kn-keyword=Des-gamma-carboxy prothrombin END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue= article-no= start-page=1017 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Identification and Modification ofPorphyromonas gingivalisCysteine Protease, Gingipain, Ideal for Screening Periodontitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chronic periodontitis is an inflammatory disease caused by the formation of oral microbial biofilms. Periodontitis is associated with general health and not only oral diseases.Porphyromonas gingivalisis a well-known keystone pathogen for periodontitis and is associated with several systemic diseases, such as diabetes mellitus and Alzheimer's disease. We previously developed a system for screening periodontitis usingP. gingivalis-specific serum immunoglobulin G (IgG) in an enzyme-linked immunosorbent assay with a sensitivity of 0.774 and a specificity of 0.586 and an area under the receiver operating characteristic curve of 0.708. However, the antigens elicited non-specific responses, since they were obtained from whole extracts of sonicated cultured bacteria. The purpose of this study was to identify antigens ideal for a sensitive and specific serum test. We identified the specific antigens using immunoaffinity columns immobilized with IgG antibodies from periodontitis patients. Liquid chromatography-tandem mass spectrometry identified 29 antigens from the elutes. Recombinant proteins for these candidates were synthesized using the wheat germ cell-free translation system and screened by dot blot analysis with serum from the columns. Three of the 16 candidates that reacted showed strongest affinities upon dot blot analysis; they included outer membrane protein 28, cysteine proteases, lysine gingipain Kgp, and arginine gingipain RgpA. Outer membrane protein 28 was not suitable for screeningP. gingivalisinfection because of its high false-negative rates. Kgp and RgpA were unstable antigens since they underwent self-digestion. They were made stable by substituting the active cysteine residues in Kgp and RgpA with alanine using site-directed mutagenesis. Using the modified antigens, we demonstrated that the patient serum IgG level against RgpA was the highest among all the antigens expressed inP. gingivalis. Moreover, the N-terminus of recombinant RgpA was excellent in differentiating between diseased and non-diseased states (with sensitivity of 0.85, specificity of 0.9, and area under the curve of 0.915). Although dot blot analysis was the only experiment used, the N-terminus of RgpA is an excellent antigen to immunologically test forP. gingivalisinfection, especially for estimating the risks for periodontitis-associated systemic diseases. In conclusion, we have developed aP. gingivalisantigen for screening periodontitis. en-copyright= kn-copyright= en-aut-name=HiraiKimito en-aut-sei=Hirai en-aut-mei=Kimito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Yamaguchi-TomikawaTomoko en-aut-sei=Yamaguchi-Tomikawa en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EguchiToru en-aut-sei=Eguchi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaedaHiroshi en-aut-sei=Maeda en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Pathophysiology?Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathophysiology?Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=R&D, Sunstar Inc. kn-affil= affil-num=4 en-affil=Department of Endodontology, Osaka Dental University kn-affil= affil-num=5 en-affil=Department of Pathophysiology?Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=screening chronic periodontitis kn-keyword=screening chronic periodontitis en-keyword=Porphyromonas gingivalis kn-keyword=Porphyromonas gingivalis en-keyword=serum IgG test kn-keyword=serum IgG test en-keyword=gingipain kn-keyword=gingipain en-keyword=specific antigen kn-keyword=specific antigen END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=22 article-no= start-page=5669 end-page=5675 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200518 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Aluminum porphyrins with quaternary ammonium halides as catalysts for copolymerization of cyclohexene oxide and CO2: metal?ligand cooperative catalysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bifunctional AlIII porphyrins with quaternary ammonium halides, 2-Cl and 2-Br, worked as excellent catalysts for the copolymerization of cyclohexene oxide (CHO) and CO2 at 120 °C. Turnover frequency (TOF) and turnover number (TON) reached 10?000 h?1 and 55?000, respectively, and poly(cyclohexene carbonate) (PCHC) with molecular weight of up to 281?000 was obtained with a catalyst loading of 0.001 mol%. In contrast, bifunctional MgII and ZnII counterparts, 3-Cl and 4-Cl, as well as a binary catalyst system, 1-Cl with bis(triphenylphosphine)iminium chloride (PPNCl), showed poor catalytic performances. Kinetic studies revealed that the reaction rate was first-order in [CHO] and [2-Br] and zero-order in [CO2], and the activation parameters were determined: ΔH‡ = 12.4 kcal mol?1, ΔS‡ = ?26.1 cal mol?1 K?1, and ΔG‡ = 21.6 kcal mol?1 at 80 °C. Comparative DFT calculations on two model catalysts, AlIII complex 2′ and MgII complex 3′, allowed us to extract key factors in the catalytic behavior of the bifunctional AlIII catalyst. The high polymerization activity and carbonate-linkage selectivity originate from the cooperative actions of the metal center and the quaternary ammonium cation, both of which facilitate the epoxide-ring opening by the carbonate anion to form the carbonate linkage in the key transition state such as TS3b (ΔH‡ = 13.3 kcal mol?1, ΔS‡ = ?3.1 cal mol?1 K?1, and ΔG‡ = 14.4 kcal mol?1 at 80 °C). en-copyright= kn-copyright= en-aut-name=DengJingyuan en-aut-sei=Deng en-aut-mei=Jingyuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=RatanasakManussada en-aut-sei=Ratanasak en-aut-mei=Manussada kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakoYuma en-aut-sei=Sako en-aut-mei=Yuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TokudaHideki en-aut-sei=Tokuda en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaedaChihiro en-aut-sei=Maeda en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HasegawaJun-ya en-aut-sei=Hasegawa en-aut-mei=Jun-ya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NozakiKyoko en-aut-sei=Nozaki en-aut-mei=Kyoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=EmaTadashi en-aut-sei=Ema en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Chemistry and Biotechnology, Graduate School of Engineering, The University of Tokyo kn-affil= affil-num=2 en-affil=Institute for Catalysis, Hokkaido University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Institute for Catalysis, Hokkaido University kn-affil= affil-num=7 en-affil=Department of Chemistry and Biotechnology, Graduate School of Engineering, The University of Tokyo kn-affil= affil-num=8 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=7 article-no= start-page=2447 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis of Dinaphtho[2,3-d:2',3'-d']anthra[1,2-b:5,6-b']dithiophene (DNADT) Derivatives: Effect of Alkyl Chains on Transistor Properties en-subtitle= kn-subtitle= en-abstract= kn-abstract=To investigate organic field-effect transistor (OFET) properties, a new thienoacene-type molecule, 4,14-dihexyldinaphtho[2,3-d:2',3'-d']anthra[1,2-b:5,6-b']dithiophene (C6-DNADT), consisting of pi-conjugated nine aromatic rings and two hexyl chains along the longitudinal molecular axis has been successfully synthesized by sequential reactions, including Negishi coupling, epoxidation, and cycloaromatization. The fabricated OFET using thin films of C6-DNADT exhibited p-channel FET properties with field-effect mobilities (mu) of up to 2.6 x 10(-2) cm(2) V-1 s(-1), which is ca. three times lower than that of the parent DNADT molecule (8.5 x 10(-2) cm(2) V-1 s(-1)). Although this result implies that the installation of relatively short alkyl chains into the DNADT core is not suitable for transistor application, the origins for the FET performance obtained in this work is fully discussed, based on theoretical calculations and solid-state structure of C6-DNADT by grazing incidence wide-angle X-ray scattering (GIWAXS) and atomic force microscopy (AFM) analyses. The results obtained in this study disclose the effect of alkyl chains introduced onto the molecule on transistor characteristics. en-copyright= kn-copyright= en-aut-name=IshidaTakumi en-aut-sei=Ishida en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SawanakaYuta en-aut-sei=Sawanaka en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ToyamaRyota en-aut-sei=Toyama en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=JiZhenfei en-aut-sei=Ji en-aut-mei=Zhenfei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MoriHiroki en-aut-sei=Mori en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishiharaYasushi en-aut-sei=Nishihara en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=organic field-effect transistor (OFET) kn-keyword=organic field-effect transistor (OFET) en-keyword=thienoacene kn-keyword=thienoacene en-keyword=p-type semiconductor kn-keyword=p-type semiconductor en-keyword=Negishi coupling reaction kn-keyword=Negishi coupling reaction en-keyword=cycloaromatization kn-keyword=cycloaromatization en-keyword=fastener effect kn-keyword=fastener effect END start-ver=1.4 cd-journal=joma no-vol=101 cd-vols= no-issue=24 article-no= start-page=245111 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Magnetotransport properties of tellurium under extreme conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study investigates the transport properties of a chiral elemental semiconductor tellurium (Te) under magnetic fields and pressure. Application of hydrostatic pressure reduces the resistivity of Te, while its temperature dependence remains semiconducting up to 4 GPa, contrary to recent theoretical and experimental studies. Application of higher pressure causes structural as well as semiconductor-metal transitions. The resulting metallic phase above 4 GPa exhibits superconductivity at 2 K along with a noticeable linear magnetoresistance effect. On the other hand, at ambient pressure, we identified metallic surface states on the as-cleaved (10?10) surfaces of Te. The nature of these metallic surface states has been systematically studied by analyzing quantum oscillations observed in high magnetic fields. We clarify that a well-defined metallic surface state exists not only on chemically etched samples that were previously reported, but also on as-cleaved ones. en-copyright= kn-copyright= en-aut-name=AkibaKazuto en-aut-sei=Akiba en-aut-mei=Kazuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobayashiKaya en-aut-sei=Kobayashi en-aut-mei=Kaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KobayashiTatsuo C. en-aut-sei=Kobayashi en-aut-mei=Tatsuo C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KoezukaRyo en-aut-sei=Koezuka en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyakeAtsushi en-aut-sei=Miyake en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GouchiJun en-aut-sei=Gouchi en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UwatokoYoshiya en-aut-sei=Uwatoko en-aut-mei=Yoshiya kn-aut-name= Yosh kn-aut-sei= Yosh kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TokunagaMasashi en-aut-sei=Tokunaga en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=The Institute for Solid State Physics, The University of Tokyo kn-affil= affil-num=5 en-affil=The Institute for Solid State Physics, The University of Tokyo kn-affil= affil-num=6 en-affil=The Institute for Solid State Physics, The University of Tokyo kn-affil= affil-num=7 en-affil=The Institute for Solid State Physics, The University of Tokyo kn-affil= affil-num=8 en-affil=The Institute for Solid State Physics, The University of Tokyo kn-affil= END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=9 article-no= start-page=1043 end-page=1052 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190319 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Acceleration of bone regeneration of horizontal bone defect in rats using collagen‐binding basic fibroblast growth factor combined with collagen scaffolds en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Basic fibroblast growth factor (bFGF) has been applied for periodontal regeneration. However, the application depends on bone defect morphology because bFGF diffuses rapidly from defect sites. In a previous study, collagen‐binding bFGF (CB‐bFGF) has been shown to enhance bone formation by collagen‐anchoring in the orthopedic field. The aim of this study is to demonstrate the efficacy of CB‐bFGF with collagen scaffolds in bone regeneration of horizontal bone defect.
Methods
Cell proliferation activity and collagen binding activity of CB‐bFGF was confirmed by WST‐8 assay and collagen binding assay, respectively. The retention of CB‐bFGF in the collagen sheet (CS) was measured by fluorescence imaging. The rat horizontal alveolar bone defect model was employed to investigate the efficacy of CB‐bFGF with collagen powder (CP). After 4 and 8 weeks, the regenerative efficacy was evaluated by microcomputed tomography, histological, and immunohistochemical analyses.
Results
CB‐bFGF had a comparable proliferation activity to bFGF and a collagen binding activity. CB‐bFGF was retained in CS longer than bFGF. At 8 weeks postoperation, bone volume, bone mineral content, and new bone area in CB‐bFGF/CP group were significantly increased compared with those in other groups. Furthermore, epithelial downgrowth was significantly suppressed in CB‐bFGF/CP group. At 4 weeks, the numbers of osteocalcin, proliferating cell nuclear antigen, and osteopontin‐positive cells at the regeneration site in CB‐bFGF/CP group were greater than those in other groups.
Conclusions
CB‐bFGF/CP effectively promoted bone regeneration of horizontal bone defect possibly by sustained release of bFGF. The potential of CB‐bFGF composite material for improved periodontal regeneration in vertical axis was shown. en-copyright= kn-copyright= en-aut-name=NakamuraShin en-aut-sei=Nakamura en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ItoTakashi en-aut-sei=Ito en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkamotoKentaro en-aut-sei=Okamoto en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MimaTakehiko en-aut-sei=Mima en-aut-mei=Takehiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UchidaKentaro en-aut-sei=Uchida en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SiddiquiYasir D. en-aut-sei=Siddiqui en-aut-mei=Yasir D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ItoMasahiro en-aut-sei=Ito en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TaiMasako en-aut-sei=Tai en-aut-mei=Masako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkuboKeisuke en-aut-sei=Okubo en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YamashiroKeisuke en-aut-sei=Yamashiro en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OmoriKazuhiro en-aut-sei=Omori en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YamamotoTadashi en-aut-sei=Yamamoto en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MatsushitaOsamu en-aut-sei=Matsushita en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Pathophysiology‐Periodontal Science, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Pathophysiology‐Periodontal Science, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Pathophysiology‐Periodontal Science, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Bacteriology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Kitasato University School of Medicine kn-affil= affil-num=6 en-affil=Department of Pathophysiology‐Periodontal Science, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Pathophysiology‐Periodontal Science, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Pathophysiology‐Periodontal Science, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Pathophysiology‐Periodontal Science, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Department of Pathophysiology‐Periodontal Science, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Periodontics and Endodontics, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Periodontics and Endodontics, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Bacteriology, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Pathophysiology‐Periodontal Science, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=bone regeneration kn-keyword=bone regeneration en-keyword=collagen kn-keyword=collagen en-keyword=drug delivery systems kn-keyword=drug delivery systems en-keyword=growth factors kn-keyword=growth factors en-keyword=periodontitis kn-keyword=periodontitis en-keyword=tissue engineering kn-keyword=tissue engineering END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=6 article-no= start-page=2350 end-page=2353 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Palladium-Catalyzed Decarbonylative Alkylation of Acyl Fluorides en-subtitle= kn-subtitle= en-abstract= kn-abstract=Palladium-catalyzed decarbonylative alkylation reactions of acyl fluorides have been developed using alkylboranes having β-hydrogens.

The hemilabile bidentate ligand DPPE plays a crucial role for retardation of the undesired β-hydride elimination. en-copyright= kn-copyright= en-aut-name=FuLiyan en-aut-sei=Fu en-aut-mei=Liyan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ChenQiang en-aut-sei=Chen en-aut-mei=Qiang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WangZhenhua en-aut-sei=Wang en-aut-mei=Zhenhua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishiharaYasushi en-aut-sei=Nishihara en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=141 cd-vols= no-issue=25 article-no= start-page=9832 end-page=9836 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=2019611 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Deoxygenative Insertion of Carbonyl Carbon into a C(sp3)?H Bond: Synthesis of Indolines and Indoles en-subtitle= kn-subtitle= en-abstract= kn-abstract=A simple deoxygenation reagent prepared in situ from commercially available Mo(CO)6 and ortho-quinone has been developed for the synthesis of indoline and indole derivatives.

Rhinosinusitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cross-linking of antigen-specific IgE bound to the high-affinity IgE receptor (Fc epsilon RI) on the surface of mast cells with multivalent antigens results in the release of mediators and development of type 2 inflammation. Fc epsilon RI expression and IgE synthesis are, therefore, critical for type 2 inflammatory disease development. In an attempt to clarify the relationship between eosinophilic chronic rhinosinusitis (ECRS) and mast cell infiltration, we analyzed mast cell infiltration at lesion sites and determined its clinical significance. Mast cells are positive for c-kit, and IgE in uncinated tissues (UT) and nasal polyps (NP) were examined by immunohistochemistry. The number of positive cells and clinicopathological factors were analyzed. Patients with ECRS exhibited high levels of total IgE serum levels and elevated peripheral blood eosinophil ratios. As a result, the number of mast cells with membranes positive for c-kit and IgE increased significantly in lesions forming NP. Therefore, we classified IgE-positive mast cells into two groups: membrane IgE-positive cells and cytoplasmic IgE-positive cells. The amount of membrane IgE-positive mast cells was significantly increased in moderate ECRS. A positive correlation was found between the membrane IgE-positive cells and the radiological severity score, the ratio of eosinophils, and the total serum IgE level. The number of cytoplasmic IgE-positive mast cells was significantly increased in moderate and severe ECRS. A positive correlation was observed between the cytoplasmic IgE-positive cells and the radiological severity score, the ratio of eosinophils in the blood, and the total IgE level. These results suggest that the process of mast cell internalization of antigens via the IgE receptor is involved in ECRS pathogenesis. en-copyright= kn-copyright= en-aut-name=GionYuka en-aut-sei=Gion en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkanoMitsuhiro en-aut-sei=Okano en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KoyamaTakahisa en-aut-sei=Koyama en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OuraTokie en-aut-sei=Oura en-aut-mei=Tokie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishikoriAsami en-aut-sei=Nishikori en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OritaYorihisa en-aut-sei=Orita en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TachibanaTomoyasu en-aut-sei=Tachibana en-aut-mei=Tomoyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=MakinoTakuma en-aut-sei=Makino en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= affil-num=1 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=2 en-affil=Department of Otolaryngology of Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Otolaryngology of Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=6 en-affil=Department of Otolaryngology, Head and Neck Surgery, Kumamoto University Graduate School kn-affil= affil-num=7 en-affil=Department of Otolaryngology, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=8 en-affil=Department of Otolaryngology of Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Otolaryngology of Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Otolaryngology of Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= en-keyword=mast cell kn-keyword=mast cell en-keyword=eosinophilic chronic rhinosinusitis kn-keyword=eosinophilic chronic rhinosinusitis en-keyword=c-kit kn-keyword=c-kit en-keyword=IgE kn-keyword=IgE END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=2 article-no= start-page=415 end-page=428 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190713 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Identification of endogenous small peptides involved in rice immunity through transcriptomics- and proteomics-based screening en-subtitle= kn-subtitle= en-abstract= kn-abstract=Small signalling peptides, generated from larger protein precursors, are important components to orchestrate various plant processes such as development and immune responses. However, small signalling peptides involved in plant immunity remain largely unknown. Here, we developed a pipeline using transcriptomics- and proteomics-based screening to identify putative precursors of small signalling peptides: small secreted proteins (SSPs) in rice, induced by rice blast fungus Magnaporthe oryzae and its elicitor, chitin. We identified 236 SSPs including members of two known small signalling peptide families, namely rapid alkalinization factors and phytosulfokines, as well as many other protein families that are known to be involved in immunity, such as proteinase inhibitors and pathogenesis-related protein families. We also isolated 52 unannotated SSPs and among them, we found one gene which we named immune response peptide (IRP) that appeared to encode the precursor of a small signalling peptide regulating rice immunity. In rice suspension cells, the expression of IRP was induced by bacterial peptidoglycan and fungal chitin. Overexpression of IRP enhanced the expression of a defence gene, PAL1 and induced the activation of the MAPKs in rice suspension cells. Moreover, the IRP protein level increased in suspension cell medium after chitin treatment. Collectively, we established a simple and efficient pipeline to discover SSP candidates that probably play important roles in rice immunity and identified 52 unannotated SSPs that may be useful for further elucidation of rice immunity. Our method can be applied to identify SSPs that are involved not only in immunity but also in other plant functions. en-copyright= kn-copyright= en-aut-name=WangPingyu en-aut-sei=Wang

Diseases Using a Behavioral Six-Step Method en-subtitle= kn-subtitle= en-abstract= kn-abstract= The assessor-blinded, parallel-design, quasi-randomized study (alternating allocation) aimed to determine the effects of the six-step method on postoperative numbers of oral bacteria, periodontal status, and atrial fibrillation (AF) among inpatients with heart diseases and periodontitis. Seventy inpatients who received preoperative periodontal treatment were quasi-randomly assigned to intervention and control groups at University Hospital. The intervention group received intensive oral hygiene instruction using a six-step method for 15 minutes per week and the control group received routine oral hygiene instruction. Significantly fewer oral bacteria were identified on the tongue at discharge compared with baseline in the intervention than the control group (ANCOVA) (large effect size, p = 0.02). Changes in scores for self-efficacy, plaque scores, probed pocket depth, and bleeding on probing between baseline and discharge were significantly greater in the intervention, than in the control group (p < 0.05). The period of postoperative AF (days) was significantly shorter in the intervention, than in the control group (p = 0.019). In conclusion, oral hygiene instruction using the six-step method decreased the numbers of oral bacteria on the tongue and improved self-efficacy, oral health behaviors, oral hygiene status, periodontal status, and period of postoperative AF among inpatients with periodontitis and heart diseases. en-copyright= kn-copyright= en-aut-name=OmoriChie en-aut-sei=Omori en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhbayashiYumiko en-aut-sei=Ohbayashi en-aut-mei=Yumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyakeMinoru en-aut-sei=Miyake en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil= Department of Preventive Dentistry, Okayama University graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil= Department of Preventive Dentistry, Okayama University graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Hospital kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Hospital kn-affil= affil-num=5 en-affil= Department of Preventive Dentistry, Okayama University graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=oral hygiene instruction kn-keyword=oral hygiene instruction en-keyword=perioperative period kn-keyword=perioperative period en-keyword=self-efficacy kn-keyword=self-efficacy en-keyword=six-step method kn-keyword=six-step method END start-ver=1.4 cd-journal=joma no-vol=109 cd-vols= no-issue= article-no= start-page=49 end-page=4961 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The List of Published by Members of the Faculty From January to December 2019. kn-title=公表学術論文等リスト2019 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=6 article-no= start-page=566 end-page=573 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical characteristics of elderly depressive patients with low metaiodobenzylguanidine uptake en-subtitle= kn-subtitle= en-abstract= kn-abstract=BACKGROUND:
Recently, depression with Lewy body pathology before the appearance of parkinsonism and cognitive dysfunction has been drawing attention. Low cardiac metaiodobenzylguanidine (MIBG) uptake is helpful for early differentiation of Lewy body disease (LBD) from late-onset psychiatric disorders even before parkinsonism or dementia appears. In this study, we used MIBG uptake as a tool in suspected LBD, and evaluated the relationship of MIBG results to clinical characteristics and depressive symptoms.
METHODS:
Fifty-two elderly inpatients with depression were included in this study. The Hamilton Depression Rating Scale (HDRS) was administered at admission, and 123 I-MIBG cardiac scintigraphy was performed. Of 52 patients, 38 had normal and 14 had reduced MIBG uptake.
RESULTS:
Correlation analyses of the late phase heart-to-mediastinum (H/M) ratio on the MIBG test and each item of the HDRS revealed that the H/M ratio was significantly correlated with scores of 'agitation', 'anxiety-somatic', and 'retardation' on the HDRS. Mean HDRS composite scores of 'somatic and psychic anxiety (Marcos)' and 'somatic anxiety/somatization factor (Pancheri)' were higher in the low uptake group than in the normal uptake group.
CONCLUSION:
Elderly patients with depression who manifested an obvious somatic anxiety tend to show low MIBG uptake, and are more likely to have Lewy body pathology. en-copyright= kn-copyright= en-aut-name=TakenoshitaShintaro en-aut-sei=Takenoshita en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TeradaSeishi en-aut-sei=Terada en-aut-mei=Seishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OshimaEtsuko en-aut-sei=Oshima en-aut-mei=Etsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamaguchiMegumi en-aut-sei=Yamaguchi en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HayashiSatoshi en-aut-sei=Hayashi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HinotsuKenji en-aut-sei=Hinotsu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=EsumiSatoru en-aut-sei=Esumi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 ORCID= affil-num=1 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Pediatric Radiology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=depression kn-keyword=depression en-keyword=elderly kn-keyword=elderly en-keyword=Lewy body disease kn-keyword=Lewy body disease en-keyword=metaiodobenzylguanidine kn-keyword=metaiodobenzylguanidine en-keyword=somatic anxiety kn-keyword=somatic anxiety END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=12 article-no= start-page=1121 end-page=1132 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=PODXL1 promotes metastasis of the pancreatic ductal adenocarcinoma by activating the C5aR/C5a axis from the tumor microenvironment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pancreatic invasive ductal adenocarcinoma (PDAC) is a representative intractable malignancy under the current cancer therapies, and is considered a scirrhous carcinoma because it develops dense stroma. Both PODXL1, a member of CD34 family molecules, and C5aR, a critical cell motility inducer, have gained recent attention, as their expression was reported to correlate with poor prognosis for patients with diverse origins including PDAC; however, previous studies reported independently on their respective biological significance. Here we demonstrate that PODXL1 is essential for metastasis of PDAC cells through its specific interaction with C5aR. In vitro assay demonstrated that PODXL1 bound to C5aR, which stabilized C5aR protein and recruited it to cancer cell plasma membranes to receive C5a, an inflammatory chemoattractant factor. PODXL1 knockout in PDAC cells abrogated their metastatic property in vivo, emulating the liver metastatic mouse model treated with anti-C5a neutralizing antibody. In molecular studies, PODXL1 triggered EMT on PDAC cells in response to stimulation by C5a, corroborating PODXL1 involvement in PDAC cellular invasive properties via specific interaction with the C5aR/C5a axis. Confirming the molecular assays, histological examination showed coexpression of PODXL1 and C5aR at the invasive front of primary cancer nests as well as in liver metastatic foci of PDAC both in the mouse metastasis model and patient tissues. Hence, the novel direct interaction between PODXL1 and the C5aR/C5a axis may provide a better integrated understanding of PDAC biological characteristics including its tumor microenvironment factors. en-copyright= kn-copyright= en-aut-name=SaitoKen en-aut-sei=Saito en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IiokaHidekazu en-aut-sei=Iioka en-aut-mei=Hidekazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaruyamaSatoshi en-aut-sei=Maruyama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SumardikaI.

We herein report a surgical patient with an extremely rapidly growing spontaneous mesenteric hematoma that we successfully diagnosed using careful radiologic examination.
Presentation of case: A 56-year-old old male presenting sudden onset lower abdominal pain was referred to our emergency department. At the time of admission, his physical examination revealed stable vital signs without radiological abnormality. On the following day, the patient suddenly presented hypotension, tachycardia, and increased abdominal pain. Contrast-enhanced computed tomography examination showed a mass with both high- and low-density areas with a 130 mm maximum diameter bordering the transverse colon. Since interventional radiologists were not available, we decided to perform emergency exploratory laparotomy. On laparotomy, a 13 × 8 cm hematoma was found in the mesentery of the transverse colon. As bleeding was noted from the branches of the middle colic artery and gastrocolic artery, these responsible vessels were ligated. The patient was finally given the diagnosis of spontaneous mesenteric hematoma.
Discussion and conclusion: The present case, initially diagnosed as enterocolitis, suddenly manifested hypovolemic shock. Close monitoring for any signs of further deterioration, as well as aggressive imaging diagnosis, enabled us to avoid delays in treatment. Early diagnosis and treatment of mesenteric hematomas are essential to prevent them from rupturing and triggering life-threatening adverse events. en-copyright= kn-copyright= en-aut-name=NakamuraShunsuke en-aut-sei=Nakamura en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamadaTaihei en-aut-sei=Yamada en-aut-mei=Taihei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NaitouHiromichi en-aut-sei=Naitou en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KogaHitoshi en-aut-sei=Koga en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamashitaHisashi en-aut-sei=Yamashita en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=GochiAkira en-aut-sei=Gochi en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Emergency Medicine, St. Mary’s Hospital kn-affil= affil-num=6 en-affil=Department of Emergency Medicine, St. Mary’s Hospital kn-affil= affil-num=7 en-affil=Department of Surgery, Ibara City Hospital kn-affil= affil-num=8 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Acute care surgery kn-keyword=Acute care surgery en-keyword=Computed tomography kn-keyword=Computed tomography en-keyword=Mesenteric hematoma kn-keyword=Mesenteric hematoma END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=8 article-no= start-page=1973 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190423 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Notch Signaling Affects Oral Neoplasm Cell Differentiation and Acquisition of Tumor-Specific Characteristics en-subtitle= kn-subtitle= en-abstract= kn-abstract= Histopathological findings of oral neoplasm cell differentiation and metaplasia suggest that tumor cells induce their own dedifferentiation and re-differentiation and may lead to the formation of tumor-specific histological features. Notch signaling is involved in the maintenance of tissue stem cell nature and regulation of differentiation and is responsible for the cytological regulation of cell fate, morphogenesis, and/or development. In our previous study, immunohistochemistry was used to examine Notch expression using cases of odontogenic tumors and pleomorphic adenoma as oral neoplasms. According to our results, Notch signaling was specifically associated with tumor cell differentiation and metaplastic cells of developmental tissues. Notch signaling was involved in the differentiation of the ductal epithelial cells of salivary gland tumors and ameloblast-like cells of odontogenic tumors. However, Notch signaling was also involved in squamous metaplasia, irrespective of the type of developmental tissue. In odontogenic tumors, Notch signaling was involved in epithelial-mesenchymal interactions and may be related to tumor development and tumorigenesis. This signaling may also be associated with the malignant transformation of ameloblastomas. Overall, Notch signaling appears to play a major role in the formation of the characteristic cellular composition and histological features of oral neoplasms, and this involvement has been reviewed here. en-copyright= kn-copyright= en-aut-name=NakanoKeisuke en-aut-sei=Nakano en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakabatakeKiyofumi en-aut-sei=Takabatake en-aut-mei=Kiyofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawaiHotaka en-aut-sei=Kawai en-aut-mei=Hotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaSaori en-aut-sei=Yoshida en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaedaHatsuhiko en-aut-sei=Maeda en-aut-mei=Hatsuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KawakamiToshiyuki en-aut-sei=Kawakami en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NagatsukaHitoshi en-aut-sei=Nagatsuka en-aut-mei=Hitoshi kn-aut-name=長塚仁 kn-aut-sei=長塚 kn-aut-mei=仁 aut-affil-num=7 ORCID= affil-num=1 en-affil= Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil= Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil= Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil= Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil= Department of Oral Pathology, School of Dentistry, Aichi Gakuin University, kn-affil= affil-num=6 en-affil= Hard Tissue Pathology Unit, Matsumoto Dental University Graduate School of Oral Medicine kn-affil= affil-num=7 en-affil= Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=cell differentiation kn-keyword=cell differentiation en-keyword=epithelial-mesenchymal interaction kn-keyword=epithelial-mesenchymal interaction en-keyword=immunohistochemistry kn-keyword=immunohistochemistry en-keyword=malignant transformation kn-keyword=malignant transformation en-keyword=notch signaling kn-keyword=notch signaling en-keyword=odontogenic tumor kn-keyword=odontogenic tumor en-keyword=pleomorphic adenoma kn-keyword=pleomorphic adenoma END start-ver=1.4 cd-journal=joma no-vol=96 cd-vols= no-issue=4-1 article-no= start-page=042410 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20171019 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Numerical calculation on a two-step subdiffusion behavior of lateral protein movement in plasma membranes en-subtitle= kn-subtitle= en-abstract= kn-abstract= A two-step subdiffusion behavior of lateral movement of transmembrane proteins in plasma membranes has been observed by using single-molecule experiments. A nested double-compartment model where large compartments are divided into several smaller ones has been proposed in order to explain this observation. These compartments are considered to be delimited by membrane-skeleton "fences" and membrane-protein "pickets" bound to the fences. We perform numerical simulations of a master equation using a simple two-dimensional lattice model to investigate the heterogeneous diffusion dynamics behavior of transmembrane proteins within plasma membranes. We show that the experimentally observed two-step subdiffusion process can be described using fence and picket models combined with decreased local diffusivity of transmembrane proteins in the vicinity of the pickets. This allows us to explain the two-step subdiffusion behavior without explicitly introducing nested double compartments. en-copyright= kn-copyright= en-aut-name=SumiTomonari en-aut-sei=Sumi en-aut-mei=Tomonari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkumotoAtsushi en-aut-sei=Okumoto en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GotoHitoshi en-aut-sei=Goto en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SekinoHideo en-aut-sei=Sekino en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science and Department of Chemistry, Faculty of Science, Okayama University kn-affil= affil-num=2 en-affil= Department of Computer Science and Engineering, Graduate School of Engineering, Toyohashi University of Technology kn-affil= affil-num=3 en-affil= Department of Computer Science and Engineering, Graduate School of Engineering, Toyohashi University of Technology kn-affil= affil-num=4 en-affil= Department of Computer Science and Engineering, Graduate School of Engineering, Toyohashi University of Technology kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=ラットを用いた化学物質曝露による生体内ホルモンレベルの変動要因解析 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=YamaguchiTakafumi en-aut-sei=Yamaguchi en-aut-mei=Takafumi kn-aut-name=山口尊史 kn-aut-sei=山口 kn-aut-mei=尊史 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=触媒的CO2変換のための新規大環状多核ニッケル錯体と亜鉛錯体 kn-title=Novel Macrocyclic Multinuclear Ni(II) and Zn(II) Complexes for Catalytic CO2 Conversions en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=BIKASH DEV NATH en-aut-sei=BIKASH DEV NATH en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=フッ化アシルのアリールシラン,アリールスタンナン,2位置換プロペンおよびエステルへの選択的な変換反応 kn-title=Selective Transformation of Acyl Fluorides to Arylsilanes, Arylstannanes, 2-Substituted Propenes, and Esters en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=WangXie en-aut-sei=Wang en-aut-mei=Xie kn-aut-name=王秀 kn-aut-sei=王 kn-aut-mei=秀 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=フッ化アシルおよび塩化アシルのニトリル,アリールボロン酸エステル,エステルへの選択的な変換反応 kn-title=Selective Transformation of Acyl Fluorides and Chlorides to Nitriles, Arylboronates, and Esters en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=WangZhenhua en-aut-sei=Wang en-aut-mei=Zhenhua kn-aut-name=王振華 kn-aut-sei=王 kn-aut-mei=振華 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=4 article-no= start-page=325 end-page=331 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=Therapeutic Outcomes of 15 Postoperative Bronchopleural Fistulas Including Seven Endoscopic Interventions en-subtitle= kn-subtitle= en-abstract= kn-abstract= Therapeutic approaches to bronchopleural fistula (BPF) closure after lung resection are surgical or endoscopic interventions. We evaluated therapeutic outcomes to determine the optimal approach. We reviewed 15 patients who had developed BPF after lung resection for thoracic malignant diseases at our institution in the 10 years since 2008. The patients were 11 men and 4 women (mean age 68 years). We performed one pneumonectomy, 6 lobectomies, 7 segmentectomies, and one partial resection for malignant diseases. The median interval from lung resection to the BPF diagnosis was 46 days. The BPF-associated mortality rate was 26.7% (4/15). The rate of successful BPF closure was 66.6% (10/15). The endoscopic and surgical intervention success rates were 14.2% (1/7) and 69.2% (9/13), respectively (p<0.01). Of 5 patients who had failed BPF treatments, 4 died, and one transferred out without BPF closure. The therapeutic outcomes were related to preoperative comorbidities, performance status at the BPF diagnosis, time intervals from lung resection to BPF diagnosis, and presence of active pneumonia. The difference between endoscopic and surgical outcomes was nonsignificant, although the surgical intervention success rate was somewhat higher. The selection of endoscopic or surgical intervention for BPF does not significantly affect therapeutic outcomes. en-copyright= kn-copyright= en-aut-name=UenoTsuyoshi en-aut-sei=Ueno

en-abstract= kn-abstract= Strains of the enteric pathogen Vibrio parahaemolyticus harboring the thermostable hemolysin (TDH) encoding gene tdh is known to cause epidemic and pandemic diarrhea. In industrialized countries, this pathogen causes sporadic or outbreaks of diarrheal illness associated with consumption of raw or improperly cooked seafood. This report describes a foodborne outbreak of gastroenteritis caused by V. parahaemolyticus in June 2011 following consumption of food served at a funeral reception held at Habra, North 24 Parganas, West Bengal, India. About 650 people attended the function, of whom 44 had acute watery diarrhea with other clinical symptoms; 35 of them were admitted to the District Hospital for the rehydration treatment. Stool specimens collected from three hospitalized cases were positive for V. parahaemolyticus, of which two strains were identified as an O4:K8 serovar and one was identified as O3:K6 serovar. The O3:K6 strain also possessed the pandemic group-specific toxRS gene target (GS), whereas the O4:K8 strains were negative. All strains were polymerase chain reaction-positive for tdh but were polymerase chain reaction-negative for trh. All of the strains were resistant to ampicillin but were pansensitive to other antimicrobials tested. Pulsed-field gel electrophoresis (PFGE) analysis using NotI showed that the O3:K6 strain was similar to that of a recent clinical strain from Kolkata, but had diverged from other strains during previous years. In contrast, PFGE analysis showed that the O4:K8 strains were closely related but differed from the Kolkata strain. en-copyright= kn-copyright= en-aut-name=ChowdhuryGoutam en-aut-sei=Chowdhury en-aut-mei=Goutam kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GhoshSantanu en-aut-sei=Ghosh en-aut-mei=Santanu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=PazhaniGururaja P. en-aut-sei=Pazhani en-aut-mei=Gururaja P. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=PaulBimal K. en-aut-sei=Paul en-aut-mei=Bimal K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MajiDipankar en-aut-sei=Maji en-aut-mei=Dipankar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MukhopadhyayAsish K. en-aut-sei=Mukhopadhyay en-aut-mei=Asish K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=RamamurthyThandavarayan en-aut-sei=Ramamurthy en-aut-mei=Thandavarayan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=2 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=3 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=4 en-affil=Integrated Disease Surveillance Program, Directorate of Health Services kn-affil= affil-num=5 en-affil=Integrated Disease Surveillance Program, Directorate of Health Services kn-affil= affil-num=6 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=7 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= en-keyword=Diarrhea kn-keyword=Diarrhea en-keyword=V. parahaemolyticus kn-keyword=V. parahaemolyticus en-keyword=Serovar kn-keyword=Serovar en-keyword=GS-PCR kn-keyword=GS-PCR en-keyword=PFGE kn-keyword=PFGE END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=1 article-no= start-page=77 end-page=80 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201902 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Flap Reconstruction for Esophageal Perforation Following Anterior Cervical Plate Fixation en-subtitle= kn-subtitle= en-abstract= kn-abstract= Anterior cervical plate fixation is a common surgical treatment for cervical spine trauma, disc herniation, or cervical spondylosis. Esophageal perforation following anterior cervical plate fixation is a rare but serious complication. Management of esophageal perforation is controversial; however, we suggest treating most cases surgically because this condition is slow to heal and often fatal. We managed 2 cases of esophageal perforation following anterior cervical plate fixation by flap reconstruction with the pectoralis major muscle in one case and a jejunal free flap in the other. Here, we report our experience and review the surgical indications. en-copyright= kn-copyright= en-aut-name=MoritaMio en-aut-sei=Morita en-aut-mei=Mio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoHiroshi en-aut-sei=Matsumoto en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShirakawaYasuhiro en-aut-sei=Shirakawa en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanabeShunsuke en-aut-sei=Tanabe en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KimataYoshihiro en-aut-sei=Kimata en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=2 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=6 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= en-keyword=anterior cervical plate fixation kn-keyword=anterior cervical plate fixation en-keyword=esophageal perforation kn-keyword=esophageal perforation en-keyword=reconstruction kn-keyword=reconstruction en-keyword=pectoralis major flap kn-keyword=pectoralis major flap en-keyword=jejunal free flap kn-keyword=jejunal free flap END start-ver=1.4 cd-journal=joma no-vol=108 cd-vols= no-issue= article-no= start-page=19 end-page=32 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The List of Published by Members of the Faculty From January to December 2018 kn-title=公表学術論文等リスト 2018 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Faculty of Agriculture, Okayama University en-aut-sei=Faculty of Agriculture, Okayama University en-aut-mei= kn-aut-name=岡山大学農学部 kn-aut-sei=岡山大学農学部 kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=108 cd-vols= no-issue= article-no= start-page=5 end-page=13 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Effect of boron deficiency on tip burn and malformed fruit incidence in strawberries kn-title=B(ホウ素)欠乏処理がイチゴのチップバーンおよび受精不良果発生に及ぼす影響 en-subtitle= kn-subtitle= en-abstract= B(ホウ素)は植物にとって必須な微量要素であり,イチゴの受精不良果発生要因の1 つである.そこで2015年度と2016年度の2 回にわたりB 欠乏がイチゴの受精不良果発生に及ぼす影響について調査した.また,2016年度はB 欠乏処理後にB 回復処理を行い,その後のイチゴの果実形態の変化についても調査した.その結果,B欠乏処理を行うと蒸散機能の低い新葉や花芽においてチップバーンが発生し,種浮き果や部分不受精を主とした受精不良果が多発した.しかし,B 回復処理を行うことでこれらの症状が改善することが明らかになった.B は受精不良果発生に関係しており,欠乏条件下で根から吸収させると急速に若い成長中の組織に転流することが示されたことから,B 栄養をコントロールすることでB 不足によるイチゴの受精不良果発生を軽減できる可能性があると考えられる. kn-abstract=Boron (B) is an essential micro element for plants and plays important roles in the synthesis and functions of cell wall. B deficiency has been reported as one of the causes of fruit malformation in strawberries. We investigated the effect of B deficiency on flower and fruit development of forced strawberries for two cropping seasons (2015-2017). In the second season, B was resupplied for B-deficient plants and we investigated changes in fruit development. When B-free nutrient solutions were supplied, tip burn began to occur in newly emerging leaves and calyx 2 to 3 months later, and fruit malformation including seedy or only partly developed fruits with undeveloped achenes occurred frequently. However, these deficient symptoms were quickly disappeared by supplying B containing nutrient solutions. In conclusion, B nutrition is closely related to the occurrence of fruit malformation through fertility of pollen and pistils, and also development of receptacle tissue in strawberries. It should be possible to reduce fruit malformation in strawberries by proper control of B nutrition. en-copyright= kn-copyright= en-aut-name=SesumiMiho en-aut-sei=Sesumi en-aut-mei=Miho kn-aut-name=瀬角美穂 kn-aut-sei=瀬角 kn-aut-mei=美穂 aut-affil-num=1 ORCID= en-aut-name=YoshidaYuichi en-aut-sei=Yoshida en-aut-mei=Yuichi kn-aut-name=吉田裕一 kn-aut-sei=吉田 kn-aut-mei=裕一 aut-affil-num=2 ORCID= en-aut-name=KinjoAkari en-aut-sei=Kinjo en-aut-mei=Akari kn-aut-name=金城朱理 kn-aut-sei=金城 kn-aut-mei=朱理 aut-affil-num=3 ORCID= en-aut-name=HidakaKei en-aut-sei=Hidaka en-aut-mei=Kei kn-aut-name=日高啓 kn-aut-sei=日高 kn-aut-mei=啓 aut-affil-num=4 ORCID= en-aut-name=GotoTanjuro en-aut-sei=Goto en-aut-mei=Tanjuro kn-aut-name=後藤丹十郎 kn-aut-sei=後藤 kn-aut-mei=丹十郎 aut-affil-num=5 ORCID= en-aut-name=YasubaKen-ichiro en-aut-sei=Yasuba en-aut-mei=Ken-ichiro kn-aut-name=安場健一郎 kn-aut-sei=安場 kn-aut-mei=健一郎 aut-affil-num=6 ORCID= en-aut-name=TanakaYoshiyuki en-aut-sei=Tanaka en-aut-mei=Yoshiyuki kn-aut-name=田中義行 kn-aut-sei=田中 kn-aut-mei=義行 aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate school of Environmental and Life Science kn-affil=岡山大学大学院 環境生命科学研究科 affil-num=2 en-affil=Graduate school of Environmental and Life Science kn-affil=岡山大学大学院 環境生命科学研究科 affil-num=3 en-affil=Graduate school of Environmental and Life Science kn-affil=岡山大学大学院 環境生命科学研究科 affil-num=4 en-affil=Asahi Kagaku Kogyo Co., Ltd.) kn-affil=旭化学工業 affil-num=5 en-affil=Graduate school of Environmental and Life Science kn-affil=岡山大学大学院 環境生命科学研究科 affil-num=6 en-affil=Graduate school of Environmental and Life Science kn-affil=岡山大学大学院 環境生命科学研究科 affil-num=7 en-affil=Graduate school of Environmental and Life Science kn-affil=岡山大学大学院 環境生命科学研究科 en-keyword=floral organs kn-keyword=floral organs en-keyword=Fragaria × ananassa Duch. kn-keyword=Fragaria × ananassa Duch. en-keyword=pistil fertility kn-keyword=pistil fertility en-keyword=receptacle growth kn-keyword=receptacle growth en-keyword=seedy fruit kn-keyword=seedy fruit END start-ver=1.4 cd-journal=joma no-vol=97 cd-vols= no-issue= article-no= start-page=134507 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20180410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Local NMR relaxation rates T-1(-1) and T-2(-1) depending on the d-vector symmetry in the vortex state of chiral and helical p-wave superconductors en-subtitle= kn-subtitle= en-abstract= kn-abstract= Local NMR relaxation rates in the vortex state of chiral and helical p-wave superconductors are investigated by the quasiclassical Eilenberger theory. We calculate the spatial and resonance frequency dependences of the local NMR spin-lattice relaxation rate T-1(-1) and spin-spin relaxation rate T-2(-1). Depending on the relation between the NMR relaxation direction and the d-vector symmetry, the local T-1(-1) and T-2(-1) in the vortex core region show different behaviors. When the NMR relaxation direction is parallel to the d-vector component, the local NMR relaxation rate is anomalously suppressed by the negative coherence effect due to the spin dependence of the odd- frequency s-wave spin-triplet Cooper pairs. The difference between the local T-1(-1) and T-2(-1) in the site-selective NMR measurement is expected to be a method to examine the d-vector symmetry of candidate materials for spin-triplet superconductors. en-copyright= kn-copyright= en-aut-name=TanakaKenta K. en-aut-sei=Tanaka en-aut-mei=Kenta K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchiokaMasanori en-aut-sei=Ichioka en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OnariSeiichiro en-aut-sei=Onari en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Physics, Okayama University kn-affil= affil-num=2 en-affil=Department of Physics, Okayama University kn-affil= affil-num=3 en-affil=Department of Physics, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20180927 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=C型肝炎ウイルスの新規耐性変異同定法とB型肝炎ウイルスの新規安定発現細胞系の構築に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OguraNaoki en-aut-sei=Ogura en-aut-mei=Naoki kn-aut-name=小倉直樹 kn-aut-sei=小倉 kn-aut-mei=直樹 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20180927 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=がん幹細胞生成におけるエピジェネティック制御に関する研究 kn-title=Study on the Epigenetic Regulation in Cancer Stem Cells Development en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Aung Ko Ko Oo en-aut-sei=Aung Ko Ko Oo en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20180927 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=水中ロボットの混濁及び昼夜光環境下での画像に基づくドッキング kn-title=Visual Docking of Underwater Vehicle Under Turbid and Day/Night Lighting Environment en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Khin Nwe Lwin en-aut-sei=Khin Nwe Lwin en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20180927 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=マクロファージにおける終末糖化産物の取り込みが細胞アポトーシスを誘導する kn-title=Phagocytosis of Advanced Glycation End Products (AGEs) in Macrophages Induces Cell Apoptosis en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=GaoYuan en-aut-sei=Gao en-aut-mei=Yuan kn-aut-name=高遠 kn-aut-sei=高 kn-aut-mei=遠 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol=97 cd-vols= no-issue=18 article-no= start-page=184510 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20180521 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fully gapped spin-singlet superconductivity in noncentrosymmetric PbTaSe2: Pb-207 nuclear magnetic resonance study en-subtitle= kn-subtitle= en-abstract= kn-abstract= We report the Pb-207 nuclear magnetic resonance (NMR) measurements on polycrystalline sample of PbTaSe2 with noncentrosymmetric crystal structure and topological electronic band.

bovine corpus luteum en-subtitle= kn-subtitle= en-abstract= kn-abstract= The corpus luteum (CL) synthesises and secretes progesterone (P4), which is essential for the establishment and maintenance of pregnancy in mammals. P4 is synthesised from cholesterol. Cholesterol is internalised by low-density lipoprotein receptor (LDLR) and/or scavenger receptor B1 (SR-BI), and is effluxed by ATP-binding cassette (ABC) transporter A1 (ABCA1) and G1 (ABCG1). To test the hypothesis that lipoprotein receptors and ABC transporters are involved in functional luteolysis, we examined the expression of LDLR, SR-BI, ABCA1 and ABCG1 in bovine CL during the luteal stages and after injection of prostaglandin (PG) F2α on Day 10 after ovulation. Expression of LDLR and SR-BI mRNA and protein was lower in the regressed luteal than late luteal stage. Injection of cows with a PGF2α did not affect LDLR mRNA and protein levels in the CL. Although expression of SR-BI mRNA did not change, SR-BI protein expression decreased 12 and 24 h after PGF2α injection. The overall findings of the present study suggest that the decreased expression of SR-BI induced by PGF2α is one of the factors responsible for the continuous decrease in P4 production during functional luteolysis. en-copyright= kn-copyright= en-aut-name=HorihataKei en-aut-sei=Horihata en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshiokaShin en-aut-sei=Yoshioka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SanoMasahiro en-aut-sei=Sano en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoYuki en-aut-sei=Yamamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimuraKoji en-aut-sei=Kimura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SkarzynskiDariusz J. en-aut-sei=Skarzynski en-aut-mei=Dariusz J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkudaKiyoshi en-aut-sei=Okuda en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Laboratory of Reproductive Physiology, Faculty of Agriculture, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Department of Reproductive Immunology and Pathology, Institute of Animal Reproduction and Food Research, Polish Academy of Sciences kn-affil= affil-num=7 en-affil=Laboratory of Reproductive Physiology, Faculty of Agriculture, Okayama University kn-affil= en-keyword=luteal phase kn-keyword=luteal phase en-keyword=ovary kn-keyword=ovary en-keyword=progesterone kn-keyword=progesterone en-keyword=prostaglandin kn-keyword=prostaglandin en-keyword=reproduction kn-keyword=reproduction END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=10 article-no= start-page=1588 end-page=1597 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=201504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genomic and non-genomic effects of progesterone on prostaglandin (PG) F2α and PGE2 production in the bovine endometrium en-subtitle= kn-subtitle= en-abstract= kn-abstract= Progesterone (P4) acts through different actuating pathways called genomic and non-genomic pathways. Here we investigated whether P4 regulates prostaglandin (PG) F2? (PGF) and PGE2 production in bovine endometrium through different pathways. Cultured endometrial cells were exposed to P4 for a short time (5-20min) or bovine serum albumin (BSA)-conjugated P4 (P4-BSA) for 24h. Progesterone treatment for 24h stimulated PGE2 production in epithelial cells, but suppressed both PGF and PGE2 production and the expression of PG-metabolising enzymes including phospholipase A2 (PLA2) and cyclooxygenase-2 (COX2) in stromal cells. Short-term (5-20min) P4 treatment did not affect PLA2 or COX2 transcript levels in either cell type. P4-BSA increased PGF and PGE2 production only in epithelial cells. Nuclear P4 receptor mRNA expression in endometrium was higher at the follicular phase than at the early- to mid-luteal stages, whereas membrane P4 receptor mRNA expression did not change throughout the oestrous cycle. The overall results suggest that P4 controls PG production by inhibiting enzymes via a genomic pathway and by stimulating signal transduction via a non-genomic pathway. Consequently, P4 may protect the corpus luteum by attenuating PGF production in stromal cells and by increasing PGE2 secretion from epithelial cells en-copyright= kn-copyright= en-aut-name=KuseMariko en-aut-sei=Kuse en-aut-mei=Mariko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakumotoRyosuke en-aut-sei=Sakumoto en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkudaKiyoshi en-aut-sei=Okuda en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Reproductive Biology Research Unit, National Institute of Agrobiological Sciences kn-affil= affil-num=3 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=cows kn-keyword=cows en-keyword=luteolysis kn-keyword=luteolysis en-keyword=steroid hormone kn-keyword=steroid hormone en-keyword=uterus kn-keyword=uterus END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=10 article-no= start-page=1479 end-page=1486 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=201505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Multiple roles of hypoxia in ovarian function: roles of hypoxia-inducible factor-related and -unrelated signals during the luteal phase en-subtitle= kn-subtitle= en-abstract= kn-abstract= There is increasing interest in the role of oxygen conditions in the microenvironment of organs because of the discovery of a hypoxia-specific transcription factor, namely hypoxia-inducible factor (HIF) 1. Ovarian function has several phases that change day by day, including ovulation, follicular growth and corpus luteum formation and regression. These phases are regulated by many factors, including pituitary hormones and local hormones, such as steroids, peptides and cytokines, as well as oxygen conditions. Hypoxia strongly induces angiogenesis because transcription of the potent angiogenic factor vascular endothelial growth factor (VEGF) is regulated by HIF1. Follicular development and luteal formation are accompanied by a marked increase in angiogenesis assisted by HIF1-VEGF signalling. Hypoxia is also one of the factors that induces luteolysis by suppressing progesterone synthesis and by promoting apoptosis of luteal cells. The present review focuses on recent studies of hypoxic conditions, as well as HIF1-regulated genes and proteins, in the regulation of ovarian function. en-copyright= kn-copyright= en-aut-name=NishimuraRyo en-aut-sei=Nishimura en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkudaKiyoshi en-aut-sei=Okuda en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Laboratory of Reproductive Endocrinology, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Reproductive Endocrinology, Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=angiogenesis kn-keyword=angiogenesis en-keyword=apoptosis kn-keyword=apoptosis en-keyword=corpus luteum kn-keyword=corpus luteum en-keyword=follicular development kn-keyword=follicular development en-keyword=luteal formation kn-keyword=luteal formation en-keyword=luteal regression kn-keyword=luteal regression en-keyword=steroidogenesis kn-keyword=steroidogenesis END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=6 article-no= start-page=673 end-page=681 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=201411 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Endothelin as a local regulating factor in the bovine oviduct en-subtitle= kn-subtitle= en-abstract= kn-abstract= Endothelin (EDN) is a possible regulating factor of oviductal motility, which is important for the transport of gametes and embryo. To clarify the factors that control the secretion of EDN in the bovine oviduct, the expression of EDNs, EDN-converting enzymes (ECEs) and EDN receptors (EDNRs) were investigated. All isoforms of EDN (EDN1-3), ECE (ECE1 and ECE2) and EDNR (EDNRA and EDNRB) were immunolocalised in the epithelial cells of the ampulla and the isthmus. EDNRs were also immunolocalised in smooth-muscle cells. The mRNA expression of EDN2 and ECE2 was higher in cultured ampullary oviductal epithelial cells than in isthmic cells. The expression of EDN1, EDN2 and ECE2 in the ampullary tissue was highest on the day of ovulation. Oestradiol-17β increased EDN2 and ECE1 expression, while progesterone increased only ECE1 expression in cultured ampullary epithelial cells. These results indicate that EDNs are produced by epithelial cells and their target site is smooth-muscle and epithelial cells, and suggest that ovarian steroids are regulators of endothelin synthesis in ampullary oviductal epithelial cells. en-copyright= kn-copyright= en-aut-name=YamamotoYuki en-aut-sei=Yamamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KohkaMisa en-aut-sei=Kohka en-aut-mei=Misa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KobayashiYoshihiko en-aut-sei=Kobayashi en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Woclawek-PotockaIzabela en-aut-sei=Woclawek-Potocka en-aut-mei=Izabela kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkudaKiyoshi en-aut-sei=Okuda en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Reproductive Immunology and Pathology, Institute of Animal Reproduction and Food Research, Polish Academy of Sciences kn-affil= affil-num=5 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=endothelin converting enzyme kn-keyword=endothelin converting enzyme en-keyword=endothelin receptor kn-keyword=endothelin receptor en-keyword=epithelial cell kn-keyword=epithelial cell en-keyword=ovarian steroids kn-keyword=ovarian steroids en-keyword=oviductal contraction and relaxation kn-keyword=oviductal contraction and relaxation END
