Various small GTPases are involved in the multinucleation and differentiation of osteoclasts. However, the roles of small GTPases regulatory molecules in osteoclast differentiation remain unclear. In the present study, we examined the role of Dennd2c, a putative guanine nucleotide exchange factor for Rab GTPases, in osteoclast differentiation. Knockdown of Dennd2c promoted osteoclast differentiation, resorption, and expression of osteoclast markers. Morphologically, Dennd2c knockdown induced the formation of larger osteoclasts with several protrusions. In contrast, overexpression of Dennd2c inhibited the multinucleation and differentiation of osteoclasts, bone resorption, and the expression of osteoclast markers. Dennd2c-overexpressing macrophages exhibited spindle-shaped mononuclear cells and long thin protrusions. Treatment of Dennd2c-overexpressing cells with the Cdc42 inhibitor ML-141 or the Rac1 inhibitor 6-thio-GTP prevented protrusion formation. Moreover, treatment of Dennd2c-overexpressing cells with the actin polymerization inhibitor latrunculin B restored multinucleated and TRAP-positive osteoclast formation. These results indicate that Dennd2c negatively regulates osteoclast differentiation and multinucleation by modulating protrusion formation in macrophages. en-copyright= kn-copyright= en-aut-name=KoyanagiYu en-aut-sei=Koyanagi en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakaiEiko en-aut-sei=Sakai en-aut-mei=Eiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamaguchiYu en-aut-sei=Yamaguchi en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FarhanaFatima en-aut-sei=Farhana en-aut-mei=Fatima kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TairaYohsuke en-aut-sei=Taira en-aut-mei=Yohsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkamotoKuniaki en-aut-sei=Okamoto en-aut-mei=Kuniaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MurataHiroshi en-aut-sei=Murata en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsukubaTakayuki en-aut-sei=Tsukuba en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Dental Pharmacology, Graduate School of Biomedical Sciences, Nagasaki University kn-affil= affil-num=2 en-affil=Department of Dental Pharmacology, Graduate School of Biomedical Sciences, Nagasaki University kn-affil= affil-num=3 en-affil=Department of Dental Pharmacology, Graduate School of Biomedical Sciences, Nagasaki University kn-affil= affil-num=4 en-affil=Department of Dental Pharmacology, Graduate School of Biomedical Sciences, Nagasaki University kn-affil= affil-num=5 en-affil=Division of Cariology and Restorative Dentistry, Department of Prosthetic Dentistry, Graduate School of Biomedical Sciences, Nagasaki University kn-affil= affil-num=6 en-affil=Department of Dental Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Division of Cariology and Restorative Dentistry, Department of Prosthetic Dentistry, Graduate School of Biomedical Sciences, Nagasaki University kn-affil= affil-num=8 en-affil=Department of Dental Pharmacology, Graduate School of Biomedical Sciences, Nagasaki University kn-affil= en-keyword=osteoclast kn-keyword=osteoclast en-keyword=actin polymerization kn-keyword=actin polymerization en-keyword=protrusion formation kn-keyword=protrusion formation en-keyword=Dennd2c kn-keyword=Dennd2c END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=8226 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Persistent homology elucidates hierarchical structures responsible for mechanical properties in covalent amorphous solids en-subtitle= kn-subtitle= en-abstract= kn-abstract=Understanding how atomic-level structures govern the mechanical properties of amorphous materials remains a fundamental challenge in solid-state physics. Under mechanical loading, amorphous materials exhibit simple affine and spatially inhomogeneous nonaffine displacements that contribute to the elastic modulus through the Born (affine) and nonaffine terms, respectively. The differences between soft local structures characterized by small Born terms or large nonaffine displacements have yet to be elucidated. This challenge is particularly complex in covalent amorphous materials such as silicon, where the medium-range order (MRO) plays a crucial role in the network structure. To address these issues, we combined molecular dynamics simulations with persistent homology analysis. Our results reveal that local structures with small Born terms are governed by short-range characteristics, whereas those with large nonaffine displacements exhibit hierarchical structures in which short-range disorder is embedded within the MRO. These hierarchical structures are also strongly correlated with low-energy localized vibrational excitations. Our findings demonstrate that the mechanical responses and dynamic properties of covalent amorphous materials are intrinsically linked to the MRO, providing a framework for understanding and tailoring their properties. en-copyright= kn-copyright= en-aut-name=MinamitaniEmi en-aut-sei=Minamitani en-aut-mei=Emi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamuraTakenobu en-aut-sei=Nakamura en-aut-mei=Takenobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ObayashiIppei en-aut-sei=Obayashi en-aut-mei=Ippei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MizunoHideyuki en-aut-sei=Mizuno en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=SANKEN, The University of Osaka kn-affil= affil-num=2 en-affil=Department of Materials and Chemistry Materials DX Research Center, National Institute of Advanced Industrial Science and Technology (AIST) kn-affil= affil-num=3 en-affil=Center for Artificial Intelligence and Mathematical Data Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Arts and Sciences, The University of Tokyo kn-affil= END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=1333 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250816 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Phosphorylated pullulan as a local drug delivery matrix for cationic antibacterial chemicals to prevent oral biofilm en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Preventing oral infections, such as oral caries and periodontal disease, helps reduce the risks of various systemic diseases. In this study, the polysaccharide pullulan produced by the black yeast Aureobasidium pullulans was modified in combination with the cationic surfactant cetylpyridinium chloride (CPC) to create a local drug delivery system, and its antibacterial potential on oral bacteria was examined in vitro.
Methods Pullulan was phosphorylated at the CH2OH residue of α6 in the maltotriose structure and mixed with CPC. Bacterial attachment of cariogenic Streptococcus mutans on hydroxyapatite plates (HAPs) treated with the phosphorylated pullulan (PP) and CPC compound (0.01% PP and 0.001– 0.03% CPC, and vice versa) was assessed by observing bacteria using a field emission scanning electron microscope (FE-SEM) and quantified through 16 S rRNA amplification via real-time polymerase chain reaction (PCR). Additionally, the quartz crystal microbalance (QCM) method was employed to evaluate the sustained release of CPC.
Results PP-CPC compound maintained significant bactericidal activity even at 0.01%, which is one-fifth of the conventional applicable concentration of CPC. Additionally, a residual mixture was detected by the hydroxyapatite sensor of the crystal oscillator microbalance detector, suggesting an unknown molecular interaction that enables the sustained release of CPC after attachment to hydroxyapatite.
Conclusions The combination of PP and CPC may contribute to the low concentration and effective prevention of oral infections, such as dental caries. en-copyright= kn-copyright= en-aut-name=Namba-KoideNaoko en-aut-sei=Namba-Koide en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 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=4 ORCID= en-aut-name=KawataYusuke en-aut-sei=Kawata en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 ORCID= 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=8 ORCID= en-aut-name=Shinoda-ItoYuki en-aut-sei=Shinoda-Ito en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=11 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=12 ORCID= affil-num=1 en-affil=Department of Periodontics and Endodontics, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Biomaterials and Bioengineering, Faculty of Dental Medicine, Hokkaido University kn-affil= affil-num=3 en-affil=Advanced Research Center for Oral and Craniofacial Sciences, Okayama University Dental School 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=Department of Periodontics and Endodontics, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Periodontics and Endodontics, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=7 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Periodontics and Endodontics, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Pathophysiology -

Nutritional status is a crucial determinant of outcomes, and the Geriatric Nutritional Risk Index (GNRI) has shown promise. This prospective study aimed to validate the GNRI as a key indicator of perioperative outcomes in oldest-old patients undergoing CRC surgery, and to establish its utility in preoperative risk stratification.
Patients and Methods: This prospective study enrolled patients aged ≥85 years undergoing elective surgery for CRC. Preoperative GNRI was calculated using the formula: GNRI=14.89×serum albumin (g/dl)+41.7×[actual body weight/ideal body weight (corresponding to body mass index 22)]. Patients were stratified into two groups: GNRI >98 and GNRI ≤98. Baseline demographics, clinical characteristics, geriatric assessments (including Geriatric-8 and EuroQol 5 dimension), and postoperative complication rates were analyzed.
Results: Twenty-four patients (median age 88 years, interquartile range=86-91) were included: 11 in the GNRI >98 group and 13 in the GNRI ≤98 group. The patients with GNRI >98 demonstrated significantly better G8 scores (median 12 vs. 11, p<0.01) and EQ-5D index values (median 88 vs. 75.0, p<0.01). The postoperative complication rate was significantly higher in the GNRI ≤98 group (p=0.02).
Conclusion: Preoperative GNRI effectively identifies oldest-old patients with CRC at increased risk for postoperative complications. A GNRI ≤98 correlates with poorer nutritional status and impaired geriatric functional parameters. These findings highlight GNRI’s utility as a simple, valuable tool for preoperative risk stratification, potentially guiding interventions to optimize outcomes in this vulnerable population. en-copyright= kn-copyright= en-aut-name=TERAISHIFUMINORI en-aut-sei=TERAISHI en-aut-mei=FUMINORI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UTSUMIMASASHI en-aut-sei=UTSUMI en-aut-mei=MASASHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YOSHIDAYUSUKE en-aut-sei=YOSHIDA en-aut-mei=YUSUKE kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SHOJIRYOHEI en-aut-sei=SHOJI en-aut-mei=RYOHEI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KANAYANOBUHIKO en-aut-sei=KANAYA en-aut-mei=NOBUHIKO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MATSUMIYUKI en-aut-sei=MATSUMI en-aut-mei=YUKI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SHIGEYASUKUNITOSHI en-aut-sei=SHIGEYASU en-aut-mei=KUNITOSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KONDOYOSHITAKA en-aut-sei=KONDO en-aut-mei=YOSHITAKA kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ITAGAKISHIORI en-aut-sei=ITAGAKI en-aut-mei=SHIORI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TAMURARIE en-aut-sei=TAMURA en-aut-mei=RIE kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MATSUOKAYOSHIKAZU en-aut-sei=MATSUOKA en-aut-mei=YOSHIKAZU kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=FUJIWARATOSHIYOSHI en-aut-sei=FUJIWARA en-aut-mei=TOSHIYOSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=INAGAKIMASARU en-aut-sei=INAGAKI en-aut-mei=MASARU kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Surgery, National Hospital Organization Fukuyama Medical Center kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, 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=Perioperative Management Center, Okayama University Hospital kn-affil= affil-num=10 en-affil=Perioperative Management Center, Okayama University Hospital kn-affil= affil-num=11 en-affil=Perioperative Management Center, 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 Surgery, National Hospital Organization Fukuyama Medical Center kn-affil= en-keyword=Geriatric nutritional risk index kn-keyword=Geriatric nutritional risk index en-keyword=oldest‑old kn-keyword=oldest‑old en-keyword=colorectal cancer kn-keyword=colorectal cancer en-keyword=short‑term outcome kn-keyword=short‑term outcome END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=89003 end-page=89024 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250519 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Security in Post-Quantum Era: A Comprehensive Survey on Lattice-Based Algorithms en-subtitle= kn-subtitle= en-abstract= kn-abstract=Lattice-based post-quantum cryptography (PQC) has attracted significant attention as a promising solution to the security challenges posed by quantum computing. Unlike traditional cryptographic algorithms, lattice-based schemes are expected to remain secure even in the presence of quantum attacks, making them essential for securing future data. Despite their strong theoretical foundations, lattice-based schemes face several practical challenges, particularly in optimizing performance and scalability for real-world applications. This survey provides a novel taxonomy that categorizes lattice-based PQC designs, with an emphasis on computational paradigms and security considerations. We systematically evaluate lattice-based PQC implementations across both software platforms, including central processing units and graphics processing units, as well as hardware platforms like field-programmable gate arrays and application-specific integrated circuits, highlighting their strengths and limitations. In addition, we explore the practical applications of lattice-based cryptography in fields such as secure communication, critical infrastructure, privacy-preserving data analytics, artificial intelligence, and trust and authentication systems. By offering a comprehensive overview of the current state of lattice-based PQC, this survey aims to provide valuable insights into the ongoing advancements and future research directions in the field as we transition to a post-quantum era. en-copyright= kn-copyright= en-aut-name=NguyenHien en-aut-sei=Nguyen en-aut-mei=Hien kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HudaSamsul en-aut-sei=Huda en-aut-mei=Samsul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NogamiYasuyuki en-aut-sei=Nogami en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NguyenTuy Tan en-aut-sei=Nguyen en-aut-mei=Tuy Tan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=School of Informatics, Computing, and Cyber Systems, Northern Arizona University kn-affil= affil-num=2 en-affil=Interdisciplinary Education and Research Field, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=School of Informatics, Computing, and Cyber Systems, Northern Arizona University kn-affil= en-keyword=Post-quantum cryptography kn-keyword=Post-quantum cryptography en-keyword=lattice-based cryptography kn-keyword=lattice-based cryptography en-keyword=number theoretic transform kn-keyword=number theoretic transform en-keyword=hardware and software implementation kn-keyword=hardware and software implementation END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue= article-no= start-page=244 end-page=256 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Postnatal expression of Cat-315-positive perineuronal nets in the SAMP10 mouse primary somatosensory cortex en-subtitle= kn-subtitle= en-abstract= kn-abstract=Perineuronal nets (PNNs) form at the end of the critical period of plasticity in the mouse primary somatosensory cortex. PNNs are said to have functions that control neuroplasticity and provide neuroprotection. However, it is not clear which molecules in PNNs have these functions. We have previously reported that Cat-315-positive molecules were not expressed in the PNNs of the senescence-accelerated model (SAM)P10 strain model mice at 12 months of age. To confirm whether the loss of Cat-315-positive molecules occurred early in life in SAMP10 mice, we examined Cat-315-positive PNNs in the primary somatosensory cortex during postnatal development. This research helps to elucidate the function of PNNs and the mechanism of cognitive decline associated with ageing. To confirm whether Cat-315-positive PNNs changed in an age-dependent manner in SAMP10 mice, we examined the primary somatosensory cortex at 21, 28, and 56 days after birth. We compared these results with those of senescence-accelerated mouse-resistant (SAMR) mice. In SAMP10 mice, Cat-315-positive PNNs were expressed in the primary somatosensory cortex early after birth, but their expression was significantly lower than that in SAMR1 mice. Many other molecules that calibrated the PNN were unchanged between SAMP10 and SAMR1 mice. This study revealed that the expression of the Cat-315 epitope was decreased in the primary somatosensory cortex of SAMP10 mice during postnatal development. SAMP10 mice have had histological abnormalities in their brains since early life. Furthermore, using SAMP10 will be useful in elucidating the mechanism of age-related abnormalities in brain function as well as in elucidating the function and structure of PNNs. en-copyright= kn-copyright= en-aut-name=UenoHiroshi en-aut-sei=Ueno en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakahashiYu en-aut-sei=Takahashi en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoriSachiko en-aut-sei=Mori en-aut-mei=Sachiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KitanoEriko en-aut-sei=Kitano en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurakamiShinji en-aut-sei=Murakami en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WaniKenta en-aut-sei=Wani en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoYosuke en-aut-sei=Matsumoto en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkamotoMotoi en-aut-sei=Okamoto en-aut-mei=Motoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IshiharaTakeshi en-aut-sei=Ishihara en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Medical Technology, Kawasaki University of Medical Welfare kn-affil= affil-num=2 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=3 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= affil-num=7 en-affil=Department of Neuropsychiatry, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Psychiatry, Kawasaki Medical School kn-affil= en-keyword=Ageing kn-keyword=Ageing en-keyword=Brain function kn-keyword=Brain function en-keyword=Neuroplasticity kn-keyword=Neuroplasticity en-keyword=Neuroprotection kn-keyword=Neuroprotection en-keyword=Cognitive decline kn-keyword=Cognitive decline END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=12 article-no= start-page=1399 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250611 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association Between Chewing Status and Steatotic Liver Disease in Japanese People Aged ≥50 Years: A Cohort Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: In this longitudinal study, the relationship between chewing status and steatotic liver disease (SLD) was examined in 3775 people aged ≥50 years who underwent medical checkups at Junpukai Health Maintenance Center in Okayama, Japan. Methods: Participants without SLD at the time of a baseline survey in 2018 were followed until 2022. Chewing status was assessed by a self-administered questionnaire. The presence or absence of SLD was ascertained from the medical records of Junpukai Health Maintenance Center. Results: A total of 541 participants (14%) were diagnosed as having a poor chewing status at baseline. Furthermore, 318 (8%) participants were newly diagnosed with SLD at follow-up. In multivariate logistic regression analyses, the presence or absence of SLD was found to be associated with the following characteristics at baseline: sex (male: odds ratio [ORs] = 1.806; 95% confidence interval [CIs]: 1.399–2.351), age (ORs = 0.969; 95% CIs: 0.948–0.991), body mass index (≥25.0 kg/m2; ORs = 1.934; 95% CIs: 1.467–2.549), diastolic blood pressure (ORs = 1.017; 95% CIs: 1.002–1.032), and chewing status (poor: ORs = 1.472; 95% CIs: 1.087–1.994). Conclusions: The results indicate that a poor chewing status was associated with SLD development after 4 years. Aggressively recommending dental visits to participants with poor chewing status may not only improve their ability to chew well but may also reduce the incidence of SLD. en-copyright= kn-copyright= en-aut-name=IwaiKomei en-aut-sei=Iwai en-aut-mei=Komei 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=AzumaTetsuji en-aut-sei=Azuma en-aut-mei=Tetsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YonenagaTakatoshi en-aut-sei=Yonenaga en-aut-mei=Takatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TabataKoichiro en-aut-sei=Tabata en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ToyamaNaoki en-aut-sei=Toyama en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KataokaKota en-aut-sei=Kataoka en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MaruyamaTakayuki en-aut-sei=Maruyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TomofujiTakaaki en-aut-sei=Tomofuji en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Community Oral Health, School of Dentistry, Asahi University 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 Community Oral Health, School of Dentistry, Asahi University kn-affil= affil-num=4 en-affil=Department of Community Oral Health, School of Dentistry, Asahi University kn-affil= affil-num=5 en-affil=Department of Community Oral Health, School of Dentistry, Asahi University kn-affil= affil-num=6 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Community Oral Health, School of Dentistry, Asahi University kn-affil= en-keyword=oral health kn-keyword=oral health en-keyword=liver diseases kn-keyword=liver diseases en-keyword=longitudinal studies kn-keyword=longitudinal studies en-keyword=mastication kn-keyword=mastication en-keyword=physical examination kn-keyword=physical examination en-keyword=surveys and questionnaires kn-keyword=surveys and questionnaires END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=15 article-no= start-page=2557 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250802 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Concept of “Platinum Sensitivity” in Endometrial Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=The concept of “platinum sensitivity” has long guided prognostic assessment and treatment selection in recurrent ovarian cancer. However, the emergence of targeted agents, such as bevacizumab and poly (ADP-ribose) polymerase inhibitors, has complicated its clinical utility. In contrast, emerging evidence suggests that platinum sensitivity may also be applicable to recurrent endometrial cancer. As in ovarian cancer, a prolonged platinum-free interval (PFI) in recurrent endometrial cancer is associated with an improved efficacy of subsequent platinum-based chemotherapy. The PFI is linearly correlated with the response rate to platinum re-administration, progression-free survival, and overall survival. Patients are typically classified as having platinum-resistant or platinum-sensitive disease based on a PFI cutoff of 6 or 12 months. However, unlike in ovarian cancer—where the duration of response to second-line platinum-based chemotherapy rarely exceeds the prior PFI (~3%)—approximately 30% of patients with recurrent endometrial cancer exhibit a sustained response to platinum rechallenge that extends beyond their preceding PFI. Despite the incorporation of immune checkpoint inhibitors into the treatment landscape of endometrial cancer, the role of platinum sensitivity in clinical decision-making—particularly regarding treatment sequencing and drug selection—remains a critical and unresolved issue. Further research is warranted to elucidate the mechanisms underlying platinum resistance and to guide optimal therapeutic strategies. en-copyright= kn-copyright= en-aut-name=NagaoShoji en-aut-sei=Nagao en-aut-mei=Shoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujikawaAtsushi en-aut-sei=Fujikawa en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ImataniRyoko en-aut-sei=Imatani en-aut-mei=Ryoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TaniYoshinori en-aut-sei=Tani en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsuokaHirofumi en-aut-sei=Matsuoka en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IdaNaoyuki en-aut-sei=Ida en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HaragaJunko en-aut-sei=Haraga en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OgawaChikako en-aut-sei=Ogawa en-aut-mei=Chikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakamuraKeiichiro en-aut-sei=Nakamura en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=endometrial cancer kn-keyword=endometrial cancer en-keyword=platinum sensitivity kn-keyword=platinum sensitivity en-keyword=platinum free interval kn-keyword=platinum free interval END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=9 article-no= start-page=4310 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Possibility of Plasma Membrane Transporters as Drug Targets in Oral Cancers en-subtitle= kn-subtitle= en-abstract= kn-abstract=Plasma membrane transporters are increasingly recognized as potential drug targets for oral cancer, particularly oral squamous cell carcinoma (OSCC). These transporters play crucial roles in cancer cell metabolism, drug resistance, and the tumor microenvironment, making them attractive targets for therapeutic intervention. Among the two main families of plasma membrane transporters, ATP-binding cassette (ABC) transporters have long been known to be involved in drug efflux and contribute to chemoresistance in cancer cells. On the other hand, solute carriers (SLCs) are also a family of transporters that facilitate the transport of various substrates, including nutrients and drugs, and have recently been shown to contribute to cancer chemosensitivity, metabolism, and proliferation. SLC transporters have been identified as potential cancer biomarkers and therapeutic targets, and their expression profiles suggest that they could be utilized in precision oncology approaches. We summarize previous reports on the expression and role of ABC and SLC transporters in oral cancer and discuss their potential as therapeutic targets. en-copyright= kn-copyright= en-aut-name=SogawaChiharu en-aut-sei=Sogawa en-aut-mei=Chiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimadaKatsumitsu en-aut-sei=Shimada en-aut-mei=Katsumitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= affil-num=1 en-affil=Department of Food and Health Sciences, Faculty of Environmental Studies, Hiroshima Institute of Technology kn-affil= affil-num=2 en-affil=Department of Clinical Phathophysiology, Matsumoto Dental University kn-affil= affil-num=3 en-affil=Department of Oral Pathology and Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=SLC transporter kn-keyword=SLC transporter en-keyword=ABC transporter kn-keyword=ABC transporter en-keyword=oral cancer kn-keyword=oral cancer en-keyword=oral squamous cell carcinoma kn-keyword=oral squamous cell carcinoma 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=20250801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=From sewage sludge to agriculture: governmental initiatives, technologies, and sustainable practices in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sewage sludge (SS), an underutilized but valuable resource for agriculture, contains essential nutrients, such as phosphorus. In Japan, where dependence on imported fertilizers is high and global price fluctuations persist, using SS as fertilizer presents a sustainable alternative aligned with circular economy goals. This review analyzes Japan’s current efforts to repurpose SS, focusing on technological developments and key policy initiatives that promote safe and effective application. Selective phosphorus recovery technologies mitigate resource depletion, while holistic approaches, such as composting and carbonization, maximize sludge utilization for agricultural applications. Government-led initiatives, including public awareness campaigns, quality assurance standards and research support, have facilitated the adoption of sludge-based fertilizers. To contextualize Japan’s position, international trends, particularly in the EU, are also examined. These comparisons reveal both common strategies and areas for policy and technological advancement, especially regarding regulation of emerging contaminants. By integrating national case studies with global perspectives, the study offers insights into the economic, environmental, and social benefits of SS reuse, contributing to Japan’s goals of resource self-sufficiency and carbon neutrality, while also informing broader sustainable agriculture transitions worldwide. en-copyright= kn-copyright= en-aut-name=NguyenThu Huong en-aut-sei=Nguyen en-aut-mei=Thu Huong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiwaraTaku en-aut-sei=Fujiwara en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamashitaHiromasa en-aut-sei=Yamashita en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TogawaHironori en-aut-sei=Togawa en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyakeHaruo en-aut-sei=Miyake en-aut-mei=Haruo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GotoMasako en-aut-sei=Goto en-aut-mei=Masako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NagareHideaki en-aut-sei=Nagare en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakamuraMasato en-aut-sei=Nakamura en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OritateFumiko en-aut-sei=Oritate en-aut-mei=Fumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IharaHirotaka en-aut-sei=Ihara en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MaedaMorihiro en-aut-sei=Maeda en-aut-mei=Morihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Graduate School of Engineering, Kyoto University kn-affil= affil-num=2 en-affil=Graduate School of Engineering, Kyoto University kn-affil= affil-num=3 en-affil=Water Supply and Sewerage Department, National Institute for Land and Infrastructure Management kn-affil= affil-num=4 en-affil=Water Supply and Sewerage Department, National Institute for Land and Infrastructure Management kn-affil= affil-num=5 en-affil=R & D Department, Japan Sewage Works Agency kn-affil= affil-num=6 en-affil=1St Research Department, Japan Institute of Wastewater Engineering and Technology kn-affil= affil-num=7 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Institute for Rural Engineering, NARO kn-affil= affil-num=9 en-affil=Institute for Rural Engineering, NARO kn-affil= affil-num=10 en-affil=Institute for Agro-Environmental Sciences, NARO kn-affil= affil-num=11 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Japan kn-keyword=Japan en-keyword=Sewage sludge kn-keyword=Sewage sludge en-keyword=Agriculture kn-keyword=Agriculture en-keyword=Sludge fertilizers kn-keyword=Sludge fertilizers en-keyword=Governmental initiatives kn-keyword=Governmental initiatives END start-ver=1.4 cd-journal=joma no-vol=156 cd-vols= no-issue=2 article-no= start-page=151 end-page=159.e1 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202502 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The greater palatine nerve and artery both supply the maxillary teeth en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background. It is generally accepted that the greater palatine nerve and artery supply the palatal mucosa, gingiva, and glands, but not the bone or tooth adjacent to those tissues. When the bony palate is observed closely, multiple small foramina are seen on the palatal surface of the alveolar process. The authors hypothesized that the greater palatine nerve and artery might supply the maxillary teeth via the foramina on the palatal surface of the alveolar process and the superior alveolar nerve and artery. The authors aimed to investigate the palatal innervation and blood supply of the maxillary teeth.
Methods. Eight cadaveric maxillae containing most teeth or alveolar sockets were selected. The mean age at the time of death was 82.4 years. The samples were examined with colored water injection, latex injection, microcomputed tomography with contrast dye, gross anatomic dissection, and histologic observation.
Results. Through both injection studies and microcomputed tomographic analysis, the authors found that the small foramina on and around the greater palatine groove connected to the alveolar process and tooth sockets. The small foramina in the greater palatine and incisive canal also continued inside the alveolar process and the tooth sockets.
Conclusions. The alveolar branches of the greater palatine nerve and artery as well as the nasopalatine nerve and sphenopalatine artery supply maxillary teeth, alveolar bone, and periodontal tissue via the palatal alveolar foramina with superior alveolar nerves and arteries.
Practical Implications. This knowledge is essential for dentists when administering local anesthetic to the maxillary teeth and performing an osteotomy. Anatomic and dental textbooks should be updated with this new knowledge for better patient care. en-copyright= kn-copyright= en-aut-name=IwanagaJoe en-aut-sei=Iwanaga en-aut-mei=Joe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeshitaYohei en-aut-sei=Takeshita en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AnbalaganMuralidharan en-aut-sei=Anbalagan en-aut-mei=Muralidharan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZouBinghao en-aut-sei=Zou en-aut-mei=Binghao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ToriumiTaku en-aut-sei=Toriumi en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KunisadaYuki en-aut-sei=Kunisada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IbaragiSoichiro en-aut-sei=Ibaragi en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TubbsR.

Berberine (BBR) is a traditional Chinese medicine that protects against these injuries. However, the mechanism of action is not fully understood.
Aims This study aimed to evaluate the protective effects of BBR against NSAID-induced intestinal injury and elucidate the underlying molecular mechanisms.
Methods We evaluated the effects of BBR on NSAID-induced intestinal injury using a combination of mouse models and human gut organoids. Mice were treated with indomethacin with or without BBR to induce small intestinal injury. Human gut organoids were exposed to NSAID, with or without BBR, to assess their direct epithelial effects. Histological analyses, cytokine measurements, and Western blotting were performed to evaluate intestinal damage, tight junction integrity, and inflammasome-associated activation.
Results In NSAID-treated mice, BBR markedly reduced ulcers and adhesions and preserved ileal Claudin-1, Occludin, and Zonula Occludens-1 (ZO-1) levels. BBR inhibited both NOD-like receptor family pyrin domain-containing 6 and NOD-like receptor family caspase recruitment domain–containing protein 4 inflammasome activation, reducing Caspase-1 maturation and downstream interleukin-1β and tumor necrosis factor-α release. In human gut organoids, BBR demonstrated comparable protective effects by directly mitigating NSAID-induced epithelial barrier disruption caused by Claudin-1 and Occludin downregulation, although it did not restore ZO-1 expression.
Conclusions BBR effectively prevented NSAID-induced small intestinal injury by maintaining tight junction integrity and inhibiting inflammasome-associated activation, indicating its potential as a therapeutic agent against such damage. 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=TakaharaMasahiro en-aut-sei=Takahara en-aut-mei=Masahiro 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=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ToyosawaJyunki en-aut-sei=Toyosawa en-aut-mei=Jyunki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AoyamaYuki en-aut-sei=Aoyama en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IgawaShoko en-aut-sei=Igawa en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamasakiYasushi en-aut-sei=Yamasaki en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=InokuchiToshihiro en-aut-sei=Inokuchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KinugasaHideaki en-aut-sei=Kinugasa en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Nonsteroidal anti-inflammatory drugs-induced small intestinal injury kn-keyword=Nonsteroidal anti-inflammatory drugs-induced small intestinal injury en-keyword=Berberine kn-keyword=Berberine en-keyword=Tight junction protein kn-keyword=Tight junction protein en-keyword=Inflammasomes kn-keyword=Inflammasomes 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=20250714 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Week 2 remission with vedolizumab as a predictor of long-term remission in patients with ulcerative colitis: a multicenter, retrospective, observational study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Aims Vedolizumab (VDZ), a gut-selective monoclonal antibody for ulcerative colitis (UC) treatment, has no established biomarkers or clinical features that predict long-term remission. Week 2 remission, a potential predictor of long-term remission, could inform maintenance treatment strategy.
Methods This retrospective, observational chart review included patients with UC in Japan who initiated VDZ between December 2018 and February 2020. Outcome measures included 14- and 54-week remission rates in patients with week 2 and non-week 2 remission (remission by week 14), 54-week remission rates in patients with week 14 remission and primary nonresponse, and predictive factors of week 2 and week 54 remission (logistic regression).
Results Overall, 332 patients with UC (176 biologic-naïve and 156 biologic-non-naïve) were included. Significantly more biologic-naïve than biologic-non-naïve patients achieved week 2 remission (36.9% vs. 28.2%; odds ratio [OR], 1.43; 95% confidence interval [CI], 1.05–1.94; P=0.0224). Week 54 remission rates were significantly different between week 14 remission and primary nonresponse (both groups: P<0.0001), and between week 2 and non-week 2 remission (all patients: OR, 2.41; 95% CI, 1.30–4.48; P=0.0052; biologic-naïve patients: OR, 2.40; 95% CI, 1.10–5.24; P=0.0280). Week 2 remission predictors were male sex, no anti-tumor necrosis factor alpha exposure, and normal/mild endoscopic findings. Week 54 remission was significantly associated with week 2 remission and no tacrolimus use.
Conclusions Week 2 remission with VDZ is a predictor of week 54 remission in patients with UC. Week 2 may be used as an evaluation point for UC treatment decisions.

associated with the effectiveness of vedolizumab in patients with ulcerative colitis: a real-world multicenter retrospective study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Aims Previous literature suggests that the response of patients with ulcerative colitis to vedolizumab may be affected by previous biologic therapy exposure. This real-world study evaluated vedolizumab treatment effectiveness in biologicnon-naïve patients.
Methods This was a multicenter, retrospective, observational chart review of records from 16 hospitals in Japan (December 1, 2018, to February 29, 2020). Included patients who had ulcerative colitis, were aged ≥ 20 years, and received at least 1 dose of vedolizumab. Outcomes included clinical remission rates from weeks 2 to 54 according to prior biologic exposure status and factors associated with clinical remission up to week 54.
Results A total of 370 eligible patients were included. Clinical remission rates were significantly higher in biologic-naïve (n=197) than in biologic-non-naïve (n=173) patients for weeks 2 to 54 of vedolizumab treatment. Higher clinical remission rates up to week 54 were significantly associated with lower disease severity (partial Mayo score ≤ 4, P= 0.001; albumin ≥ 3.0, P= 0.019) and the duration of prior anti-tumor necrosis factor α (anti-TNFα) therapy (P= 0.026). Patients with anti-TNFα therapy durations of < 3 months, 3 to < 12 months, and ≥ 12 months had clinical remission rates of 28.1%, 32.7%, and 60.0%, respectively (P= 0.001 across groups).
Conclusions The effectiveness of vedolizumab in biologic-non-naïve patients was significantly influenced by duration of prior anti-TNFα therapy.

en-title= kn-title=Real-World Effectiveness and Safety of Vedolizumab in Patients ≥ 70 Versus < 70 Years With Ulcerative Colitis: Multicenter Retrospective Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Aim: Vedolizumab (VDZ) is often used in older patients with ulcerative colitis (UC) in clinical practice; however, real-world evidence is still limited, including in those with late-onset UC.
Methods: This post hoc analysis of a multicenter, retrospective, observational chart review, enrolling 370 patients with UC receiving VDZ between December 2018 and February 2020, compared effectiveness and safety of VDZ among patients ≥ 70 (n = 40) versus < 70 years (n = 330), and among patients ≥ 70 years with and without late-onset UC (age at disease onset: ≥ 70 [n = 13] versus < 70 years [n = 26]).
Results: There were no differences between patients ≥ 70 and < 70 years in clinical remission rates (week 6: 57.5% vs. 47.6%, p = 0.9174; week 14: 62.5% vs. 54.8%, p = 0.1317; week 54: 47.5% vs. 46.4%, p = 0.8149), primary nonresponse (10.0% vs. 15.5%, p = 0.6248), loss of response (12.5% vs. 9.4%, p = 0.5675), or overall safety. Among patients ≥ 70 years, the incidence of adverse drug reactions was numerically greater in those with concomitant corticosteroids than in those without. For older patients with and without late-onset UC, week 54 remission rates were 23.1% versus 57.7% (p = 0.0544); surgery was reported in 3/13 versus 2/26 patients and hospitalization in 5/13 versus 6/26 patients. One death was reported in patients with late-onset UC.
Conclusions: VDZ effectiveness and safety were similar in patients ≥ 70 and < 70 years; VDZ may be a suitable treatment option for patients ≥ 70 years with UC. Patients with late-onset UC tended to have more frequent surgery/hospitalization and lower effectiveness than those without, possibly necessitating greater caution when using VDZ.

real-world study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Aims The objectives of this real-world study were to determine 1-year persistence with vedolizumab in patients with ulcerative colitis and to evaluate factors contributing to loss of response.
Methods In this multicenter, retrospective, observational chart review, patients with moderately to severely active ulcerative colitis who received ≥ 1 dose of vedolizumab in clinical practice at 16 tertiary hospitals in Japan (from December 2018 through February 2020) were enrolled.
Results Persistence with vedolizumab was 64.5% (n = 370); the median follow-up time was 53.2 weeks. Discontinuation due to loss of response among initial clinical remitters was reported in 12.5% (35/281) of patients. Multivariate analysis showed that concomitant use of tacrolimus (odds ratio [OR], 2.76; 95% confidence interval [CI], 1.00–7.62; P= 0.050) and shorter disease duration (OR for median duration ≥ 7.8 years vs. < 7.8 years, 0.33; 95% CI, 0.13–0.82; P= 0.017) were associated with discontinuation due to loss of response. Loss of response was not associated with prior use of anti-tumor necrosis factor alpha therapy, age at the time of treatment, disease severity, or concomitant corticosteroids or immunomodulators. Of the 25 patients with disease duration < 1 year, 32.0% discontinued due to loss of response.
Conclusions Persistence with vedolizumab was consistent with previous reports. Use of tacrolimus and shorter disease duration were the main predictors of decreased persistence. en-copyright= kn-copyright= en-aut-name=KobayashiTaku en-aut-sei=Kobayashi en-aut-mei=Taku

Patient en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 55-year-old obese Japanese male with left pneumothorax presented to our hospital. Bilateral pulmonary emphysema was confirmed. Persistent air leakage was observed, and a thoracoscopic bullectomy was performed. Although the thoracoscopic bullectomy was completed uneventfully, pre-extubation chest X-ray imaging indicated hyper-lucency occupying the right upper part of the thoracic cavity, suggesting right-sided pneumothorax. CT imaging indicated a right-upper-lobe expanded bulla. Extubation was performed, and the hyperinflated bulla gradually deflated. Careful management of bulla expansion and respiratory status may be necessary for patients with obesity and large bullae, especially in one-lung ventilation cases. en-copyright= kn-copyright= en-aut-name=MatsubaraKei en-aut-sei=Matsubara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=HiranoYutaka en-aut-sei=Hirano en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiwaraToshiya en-aut-sei=Fujiwara en-aut-mei=Toshiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Thoracic Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=2 en-affil=Department of Thoracic Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=3 en-affil=Department of Thoracic Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=4 en-affil=Department of Thoracic Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= en-keyword=giant bulla kn-keyword=giant bulla en-keyword=pneumothorax kn-keyword=pneumothorax en-keyword=obesity kn-keyword=obesity en-keyword=positive pressure ventilation kn-keyword=positive pressure ventilation en-keyword=one lung ventilation kn-keyword=one lung ventilation END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=4 article-no= start-page=269 end-page=278 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Femoral and Global Femoral Offset, but not Anteroposterior Offset, to Improve Postoperative Outcomes Following Total Hip Arthroplasty: Considerations Independent of the Contralateral Side en-subtitle= kn-subtitle= en-abstract= kn-abstract=The global femoral offset (the sum of the acetabular and femoral offsets) influences outcomes after total hip arthroplasty (THA). The optimal offset using plain radiographs has been reported, but internal and external rotations of the hip affect the offset value, producing unclear results when the nonsurgical side is not intact. We investigated the relationship between a functional hip score, i.e., the Harris Hip Score (HHS) and its effect on the post-THA anteroposterior and lateral offsets, and we sought to identify the optimal offset value. The cases of 158 patients with hemilateral hip osteoarthritis who underwent THA at a single center were retrospectively analyzed in this cross-sectional study. Three-dimensional pelvic and femoral models generated from computed tomography were used to examine several parameters, and the results revealed a significant binomial correlation among the modified HHS and femoral and global femoral offsets, with maximum values of 21.3 mm and 40 mm/100 cm body height, respectively. Pelvic and femoral parameters were measured and evaluated via alignment with a specific coordinate system. Our findings indicate that preoperative planning using these parameters may improve postoperative hip function, even when the nonoperative side is unsuitable for use as a reference, as in bilateral hip osteoarthritis cases. en-copyright= kn-copyright= en-aut-name=ImaiNorio en-aut-sei=Imai en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiranoYuki en-aut-sei=Hirano en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HommaDaisuke en-aut-sei=Homma en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EndoYuki en-aut-sei=Endo en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HorigomeYoji en-aut-sei=Horigome en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuzukiHayato en-aut-sei=Suzuki en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawashimaHiroyuki en-aut-sei=Kawashima en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Division of Comprehensive Musculoskeletal Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=2 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=3 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=4 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=5 en-affil=Division of Comprehensive Musculoskeletal Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=6 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=7 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= en-keyword=total hip arthroplasty kn-keyword=total hip arthroplasty en-keyword=global femoral offset kn-keyword=global femoral offset en-keyword=postoperative outcome kn-keyword=postoperative outcome en-keyword=three-dimensional analysis kn-keyword=three-dimensional analysis en-keyword=anteroposterior offset kn-keyword=anteroposterior offset END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=4 article-no= start-page=261 end-page=267 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Outcome of Decompression Surgery Following Rapid Neurological Deterioration in Patients with Spinal Cord Injury Without Radiographic Evidence of Trauma (SCIWORET) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cervical spondylotic myelopathy (CSM) and ossification of the posterior longitudinal ligament (OPLL) increase the likelihood of spinal cord injury without radiographic evidence of trauma (SCIWORET).

In EE, neurocognitive functions and behavior are impaired by intense epileptiform electroencephalogram (EEG) activity. Hypotheses of pathophysiological mechanisms behind EE are reviewed to contribute to an effective solution for EE.
Review: Current hypotheses are as follows: 1) neuronal dysfunction based on genetic abnormalities that may affect neurocognitive functions and epilepsy separately; 2) impairment of synaptic homeostasis during sleep that may be responsible for DEE/EE with spike-and-wave activation in sleep; 3) abnormal subcortical regulation of the cerebral cortex; 4) abnormal cortical metabolism and hemodynamics with impairment of the neural network including default mode network; 5) neurotransmitter imbalance and disordered neural excitability; 6) the effects of neuroinflammation that may be caused by epileptic seizures and in turn aggravate epileptogenesis; 7) the interaction between physiological and pathological high-frequency EEG activity; etc. The causal relationship between epileptiform EEG activity and neurocognitive dysfunctions is small in DEE based on genetic abnormalities and it is largely unestablished in the other hypothetical mechanisms.
Conclusion: We have not yet found answers to the question of whether the single-central or multiple derangements are present and what seizures and intense epileptiform EEG abnormalities mean in EE. We need to continue our best efforts in both aspects to elucidate the pathophysiological mechanisms of DEE/EE and further develop epilepsy treatment and precision medicine. en-copyright= kn-copyright= en-aut-name=KobayashiKatsuhiro en-aut-sei=Kobayashi en-aut-mei=Katsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShibataTakashi en-aut-sei=Shibata en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsuchiyaHiroki en-aut-sei=Tsuchiya en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AkiyamaMari en-aut-sei=Akiyama en-aut-mei=Mari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AkiyamaTomoyuki en-aut-sei=Akiyama en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Pediatrics, Asahigawaso Rehabilitation and Medical Center kn-affil= affil-num=2 en-affil=Department of Pediatric Neurology, Okayama University Hospital and Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pediatric Neurology, Okayama University Hospital and Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pediatric Neurology, Okayama University Hospital and Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pediatric Neurology, Okayama University Hospital and Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Behavior kn-keyword=Behavior en-keyword=Childhood epilepsy kn-keyword=Childhood epilepsy en-keyword=Cognitive function kn-keyword=Cognitive function en-keyword=Developmental and epileptic encephalopathy kn-keyword=Developmental and epileptic encephalopathy en-keyword=Regression kn-keyword=Regression END start-ver=1.4 cd-journal=joma no-vol=508 cd-vols= no-issue= article-no= start-page=111242 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202509 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Enhanced aboveground biomass density estimation in Central Vietnamese forests en-subtitle= kn-subtitle= en-abstract= kn-abstract=Accurate estimation of spatially explicit forest aboveground biomass density (AGBD) is essential for supporting climate change mitigation strategies. Recent studies have demonstrated the predictive effectiveness of the random forest (RF) algorithm in forest AGBD estimation utilizing multi-source remote sensing (RS) data. However, the RF-based estimates may be further enhanced by integrating RF with kriging techniques that account for spatial autocorrelation in model residuals. Therefore, we investigated the performance of random forest ordinary kriging (RFOK) and random forest co-kriging (RFCK) for estimating AGBD in Central Vietnamese forests using Advanced Land Observing Satellite-2 Phased Array L-band Synthetic Aperture Radar-2 (ALOS-2 PALSAR-2), Sentinel-1 (S1), and Sentinel-2 (S2) imageries. 277 predictors, including spectral bands, radar backscatter coefficients, vegetation indices, biophysical variables, and texture metrics, were derived from these RS datasets and statistically linked to field measurements from 104 geo-referenced forest inventory plots. The results showed that textures, modified chlorophyll absorption ratio index (MCARI), and radar backscatters were key contributors to AGBD variability. The fusion of ALOS-2 PALSAR-2 and S2 data yielded the highest RF performance, with coefficient of determination (R2), root mean square error (RMSE), and mean absolute error (MAE) achieving 0.75, 39.15 t.ha-1, and 32.20 t.ha-1, respectively. Incorporating interpolated residuals by ordinary kriging and co-kriging into RF predictions enhanced estimation accuracy, with relative improvements of 5.74–7.04 % in R2, 8.73–10.91 % in RMSE, and 13.62–15.27 % in MAE, yet these gains remained limited. Although RFOK achieved marginally better accuracy (R2 = 0.80, RMSE = 34.88 t.ha-1, MAE = 27.28 t.ha-1) compared to RFCK (R2 = 0.79, RMSE = 35.73 t.ha-1, MAE = 27.81 t.ha-1), the latter reduced estimation bias more effectively, likely due to the inclusion of elevation as a covariate in the co-kriging process. These findings underscore the potential of the hybrid RF-kriging frameworks for improving spatial AGBD estimation, offering a robust approach for carbon accounting in tropical ecosystems. en-copyright= kn-copyright= en-aut-name=HoViet Hoang en-aut-sei=Ho en-aut-mei=Viet Hoang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoritaHidenori en-aut-sei=Morita en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BachoferFelix en-aut-sei=Bachofer en-aut-mei=Felix kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HoThanh Ha en-aut-sei=Ho en-aut-mei=Thanh Ha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=German Aerospace Center (DLR), Earth Observation Center kn-affil= affil-num=4 en-affil=University of Agriculture and Forestry, Hue University kn-affil= en-keyword=Forest aboveground biomass density kn-keyword=Forest aboveground biomass density en-keyword=Random forest kn-keyword=Random forest en-keyword=Ordinary kriging kn-keyword=Ordinary kriging en-keyword=Co-kriging kn-keyword=Co-kriging en-keyword=Multispectral kn-keyword=Multispectral en-keyword=Multi-frequency synthetic aperture radar kn-keyword=Multi-frequency synthetic aperture radar END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=5 article-no= start-page=1554 end-page=1577 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250405 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparison of geostatistics, machine learning algorithms, and their hybrid approaches for modeling soil organic carbon density in tropical forests en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Understanding the spatial variability of soil organic carbon density (SOCD) in tropical forests is necessary for efficient climate change mitigation initiatives. However, accurately modeling SOCD in these landscapes is challenging due to low-density sampling efforts and the limited availability of in-situ data caused by constrained accessibility. In this study, we aimed to explore the most suitable modeling technique for SOCD estimation in the context of tropical forest ecosystems.
Methods To support the research, thirty predictor covariates derived from remote sensing data, topographic attributes, climatic factors, and geographic positions were utilized, along with 104 soil samples collected from the top 30 cm of soil in Central Vietnamese tropical forests. We compared the effectiveness of geostatistics (ordinary kriging, universal kriging, and kriging with external drift), machine learning (ML) algorithms (random forest and boosted regression tree), and their hybrid approaches (random forest regression kriging and boosted regression tree regression kriging) for the prediction of SOCD. Prediction accuracy was evaluated using the coefficient of determination (R2), the root mean squared error (RMSE), and the mean absolute error (MAE) obtained from leave-one-out cross-validation.
Results The study results indicated that hybrid approaches performed best in predicting forest SOCD with the greatest values of R2 and the lowest values of MAE and RMSE, and the ML algorithms were more accurate than geostatistics. Additionally, the prediction maps produced by the hybridization showed the most realistic SOCD pattern, whereas the kriged maps were prone to have smoother patterns, and ML-based maps were inclined to possess more detailed patterns. The result also revealed the superiority of the ML plus residual kriging approaches over the ML models in reducing the underestimation of large SOCD values in high-altitude mountain areas and the overestimation of low SOCD values in low-lying terrain areas.
Conclusion Our findings suggest that the hybrid approaches of geostatistics and ML models are most suitable for modeling SOCD in tropical forests. en-copyright= kn-copyright= en-aut-name=HoViet Hoang en-aut-sei=Ho en-aut-mei=Viet Hoang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoritaHidenori en-aut-sei=Morita en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HoThanh Ha en-aut-sei=Ho en-aut-mei=Thanh Ha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BachoferFelix en-aut-sei=Bachofer en-aut-mei=Felix kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NguyenThi Thuong en-aut-sei=Nguyen en-aut-mei=Thi Thuong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=University of Agriculture and Forestry, Hue University kn-affil= affil-num=4 en-affil=German Aerospace Center (DLR), Earth Observation Center kn-affil= affil-num=5 en-affil=University of Agriculture and Forestry, Hue University kn-affil= en-keyword=Digital soil mapping kn-keyword=Digital soil mapping en-keyword=Hybrid approaches kn-keyword=Hybrid approaches en-keyword=Kriging kn-keyword=Kriging en-keyword=Machine learning kn-keyword=Machine learning en-keyword=Soil organic carbon density kn-keyword=Soil organic carbon density en-keyword=Tropical forests kn-keyword=Tropical forests END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=3 article-no= start-page=79 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association of the expression of 5‑FU biomarkers with aging and prognosis in elderly patients with lung cancer treated with S‑1 adjuvant chemotherapy: Follow‑up results of the Setouchi Lung Cancer Group Study 1201 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Managing elderly patients presents several challenges because of age‑related declines; however, age should not be the sole determinant for adjuvant treatment decisions in patients with non‑small cell lung cancer (NSCLC). Moreover, age may affect the expression of 5‑fluorouracil (5‑FU) biomarkers. The present study assessed: i) The effect of age on the expression levels of 5‑FU biomarkers by analyzing a public database; and ii) the ability of these biomarkers to predict clinical outcomes in elderly patients with NSCLC who underwent complete resection in the Setouchi Lung Cancer Group Study 1201 (SCLG1201) followed by S‑1 adjuvant chemotherapy. Changes in gene expression levels across age groups were assessed by analyzing The Cancer Genome Atlas (TCGA) database. The expression of 5‑FU biomarkers, including thymidylate synthase (TS), dihydropyrimidine dehydrogenase (DPD), orotate phosphoribosyltransferase, epidermal growth factor receptor (EGFR) and excision repair cross‑complementation group 1 (ERCC1), were assessed via quantitative reverse‑transcription PCR assays in 89 elderly patients (≥75 years) with NSCLC who received adjuvant chemotherapy with oral fluoropyrimidine prodrug S‑1 in the SLCG1201 trial. TCGA database analysis (n=955) showed that TS expression decreased significantly with aging, especially in the age group ≥75. In the SCLG1201 trial, univariate analysis revealed that EGFR upregulation and TS downregulation were correlated with favorable recurrence‑free survival (RFS) and overall survival (OS), respectively. Multivariate analysis demonstrated that pathological stage was an independent prognostic factor for both RFS and OS. EGFR mutations were associated with upregulation of DPD and EGFR, and downregulation of TS and ERCC1. In conclusion, although pathological stage is an independent prognostic factor for survival, EGFR upregulation and TS downregulation may be a greater predictor of clinical outcomes in elderly patients with NSCLC treated with S‑1 adjuvant chemotherapy. The age‑related decrease in TS expression supports the potential benefit of 5‑FU therapies in elderly patients. Nonetheless, further research is warranted to validate these results. en-copyright= kn-copyright= en-aut-name=SohJunichi en-aut-sei=Soh en-aut-mei=Junichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoHiromasa en-aut-sei=Yamamoto en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkumuraNorihito en-aut-sei=Okumura en-aut-mei=Norihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuzukiHiroyuki en-aut-sei=Suzuki en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakataMasao en-aut-sei=Nakata en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiwaraToshiya en-aut-sei=Fujiwara en-aut-mei=Toshiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=GembaKenicehi en-aut-sei=Gemba en-aut-mei=Kenicehi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SanoIsao en-aut-sei=Sano en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujinagaTakuji en-aut-sei=Fujinaga en-aut-mei=Takuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KataokaMasafumi en-aut-sei=Kataoka en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TerasakiYasuhiro en-aut-sei=Terasaki en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=FujimotoNobukazu en-aut-sei=Fujimoto en-aut-mei=Nobukazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 ORCID= en-aut-name=KosakaShinji en-aut-sei=Kosaka en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=YamashitaMotohiro en-aut-sei=Yamashita en-aut-mei=Motohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=InokawaHidetoshi en-aut-sei=Inokawa en-aut-mei=Hidetoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=InoueMasaaki en-aut-sei=Inoue en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=NakamuraHiroshige en-aut-sei=Nakamura en-aut-mei=Hiroshige kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= en-aut-name=YamashitaYoshinori en-aut-sei=Yamashita en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=19 ORCID= en-aut-name=TakahashiYuta en-aut-sei=Takahashi en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=20 ORCID= en-aut-name=TorigoeHidejiro en-aut-sei=Torigoe en-aut-mei=Hidejiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=21 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=22 ORCID= en-aut-name=TomidaShuta en-aut-sei=Tomida en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=23 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=24 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=25 ORCID= en-aut-name=MoritaSatoshi en-aut-sei=Morita en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=26 ORCID= en-aut-name=MatsuoKeitaro en-aut-sei=Matsuo en-aut-mei=Keitaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=27 ORCID= en-aut-name=SakamotoJunichi en-aut-sei=Sakamoto en-aut-mei=Junichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=28 ORCID= en-aut-name=DateHiroshi en-aut-sei=Date en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=29 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=30 ORCID= affil-num=1 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Thoracic Surgery, Kurashiki Central Hospital kn-affil= affil-num=4 en-affil=Department of Chest Surgery, Fukushima Medical University Hospital kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery, Kawasaki Medical School Hospital kn-affil= affil-num=6 en-affil=Department of Thoracic Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=7 en-affil=Department of Respiratory Medicine, Chugoku Central Hospital, Fukuyama, Hiroshima 720‑0001, Japan;

Yet, it remains unexplored whether maternal circadian rhythms during pregnancy influence fetal rhythms and impact long-term susceptibility to dietary challenges in offspring. Here, we demonstrate that circadian disruption during pregnancy decreased placental and neonatal weight yet retained transcriptional and structural maturation. Intriguingly, diet-induced obesity was exacerbated in parallel with arrhythmic feeding behavior, hypothalamic leptin resistance, and hepatic circadian reprogramming in offspring of chronodisrupted mothers. In utero circadian desynchrony altered the phase-relationship between the mother and fetus and impacted placental efficiency. Temporal feeding restriction in offspring failed to fully prevent obesity, whereas the circadian alignment of caloric restriction with the onset of the active phase virtually ameliorated the phenotype. Thus, maternal circadian rhythms during pregnancy confer adaptive properties to metabolic functions in offspring and provide insights into the developmental origins of health and disease.

integration via CENH3 chromatin in Arabidopsis en-subtitle= kn-subtitle= en-abstract= kn-abstract=In organisms ranging from vertebrates to plants, major components of centromeres are rapidly evolving repeat sequences, such as tandem repeats (TRs) and transposable elements (TEs), which harbour centromere-specific histone H3 (CENH3)1,2. Complete centromere structures recently determined in human and Arabidopsis suggest frequent integration and purging of retrotransposons within the TR regions of centromeres3,4,5. Despite the high impact of ‘centrophilic’ retrotransposons on the paradox of rapid centromere evolution, the mechanisms involved in centromere targeting remain poorly understood in any organism. Here we show that both Ty3 and Ty1 long terminal repeat retrotransposons rapidly turnover within the centromeric TRs of Arabidopsis species. We demonstrate that the Ty1/Copia element Tal1 (Transposon of Arabidopsis lyrata 1) integrates de novo into regions occupied by CENH3 in Arabidopsis thaliana, and that ectopic expansion of the CENH3 region results in spread of Tal1 integration regions. The integration spectra of chimeric TEs reveal the key structural variations responsible for contrasting chromatin-targeting specificities to centromeres versus gene-rich regions, which have recurrently converted during the evolution of these TEs. Our findings show the impact of centromeric chromatin on TE-mediated rapid centromere evolution, with relevance across eukaryotic genomes. en-copyright= kn-copyright= en-aut-name=TsukaharaSayuri

Specific Morphology as a Prognostic Factor in Esophageal Squamous Cell Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Angiogenesis is essential for tumor progression. Microvessel density (MVD) is a widely used histological method to assess angiogenesis using immunostained sections, but its prognostic significance in esophageal cancer remains controversial. Recently, the evaluation of microvascular architecture has gained importance as a method to assess tumor aggressiveness. The present study aimed to identify the histological characteristics of tumor microvessels that are associated with the aggressiveness of esophageal squamous cell carcinoma.
Patients and Methods A total of 108 esophageal squamous cell carcinoma tissues were immunohistochemically stained with blood vessel markers and angiogenesis-related markers, including CD31, alpha smooth muscle actin, vascular endothelial growth factor A (VEGF-A), CD206, and D2-40. MVD, microvessel pericyte coverage index (MPI), and tumor vascular morphology were evaluated by microscopy.
Results MVD was significantly associated with patient outcomes, whereas neither MPI nor VEGF-A expression throughout the tumor showed a significant correlation. In addition, the presence of blood vessels encircling clusters of tumor cells, termed C-shaped microvessels, and excessively branching microvessels, termed X-shaped microvessels, was significantly associated with poor prognosis. These vessel types were also correlated with clinicopathological parameters, including deeper invasion of the primary tumor, presence of lymph node metastasis, advanced pathological stage, and distant metastasis. Focal VEGF-A immunoexpression in tumor cells was higher in areas containing C-shaped or X-shaped microvessels compared with areas lacking these vessel morphologies.
Conclusions The data suggest that tumor microvessels with specific morphologies (C-shaped and X-shaped microvessels) may serve as a promising prognostic factor in esophageal squamous cell carcinoma. en-copyright= kn-copyright= en-aut-name=TunHnin Thida en-aut-sei=Tun en-aut-mei=Hnin Thida kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=NishimuraSeitaro en-aut-sei=Nishimura en-aut-mei=Seitaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KunitomoTomoyoshi en-aut-sei=Kunitomo en-aut-mei=Tomoyoshi 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=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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 Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, 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= en-keyword=Esophageal neoplasms kn-keyword=Esophageal neoplasms en-keyword=Angiogenesis kn-keyword=Angiogenesis en-keyword=Microvessel density kn-keyword=Microvessel density en-keyword=Pericytes kn-keyword=Pericytes en-keyword=VEGF-A kn-keyword=VEGF-A en-keyword=Immunohistochemistry kn-keyword=Immunohistochemistry en-keyword=Prognosis kn-keyword=Prognosis END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=26 article-no= start-page=12024 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Collective motions in the primary coordination sphere: a critical functional framework for catalytic activity of the oxygen-evolving complex of photosystem II en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photosynthetic water oxidation, vital for dioxygen production and light energy conversion, is catalyzed by the oxygen-evolving complex of photosystem II, where the inorganic Mn4CaO5 cluster acts as the catalytic core. In this study, we investigate the functional significance of collective motions of amino acid side chains within the primary coordination sphere of the Mn cluster, focusing on their role in modulating the energetic demands for catalytic transformations in the S3 state. We applied regularized canonical correlation analysis to quantitatively correlate the three-dimensional arrangement of coordinating atoms with catalytic driving forces computed via density functional theory. Our analysis reveals that distinct collective side chain motions profoundly influence the energetic requirements for structural reconfigurations of the Mn cluster, achieved through expansion and contraction of the ligand cavity while fine-tuning its geometry to stabilize key intermediates. Complementary predictions from a neural network-based machine learning model indicate that the coordination sphere exerts a variable energetic impact on the catalytic transformations of the Mn cluster, depending on the S-state environment. Integrated computational analyses suggest that the extended lifetime of the S3YZ˙ state, consistently observed after three flash illuminations, may result from slow, progressive protein dynamics that continuously reshape the energy landscape, thereby shifting the equilibrium positions of rapid, reversible chemical processes over time. Overall, our findings demonstrate that collective motions in the primary coordination sphere constitute an active, dynamic framework essential for the efficient execution of multi-electron catalysis under ambient conditions, while simultaneously achieving a high selectivity with irreversible nature required for effective 3O2 evolution. en-copyright= kn-copyright= en-aut-name=IsobeHiroshi en-aut-sei=Isobe en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiTakayoshi en-aut-sei=Suzuki en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugaMichihiro en-aut-sei=Suga en-aut-mei=Michihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=YamaguchiKizashi en-aut-sei=Yamaguchi en-aut-mei=Kizashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, 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= affil-num=5 en-affil=Center for Quantum Information and Quantum Biology, Osaka University kn-affil= 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=12 cd-vols= no-issue=18 article-no= start-page=2413456 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250320 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cryo-EM Analysis of a Tri-Heme Cytochrome-Associated RC-LH1 Complex from the Marine Photoheterotrophic Bacterium Dinoroseobacter Shibae en-subtitle= kn-subtitle= en-abstract= kn-abstract=The reaction center-light harvesting 1 (RC-LH1) complex converts solar energy into electrical energy, driving the initiation of photosynthesis. The authors present a cryo-electron microscopy structure of the RC-LH1 isolated from a marine photoheterotrophic bacterium Dinoroseobacter shibae. The RC comprises four subunits, including a three-heme cytochrome (Cyt) c protein, and is surrounded by a closed LH ring composed of 17 pairs of antenna subunits. Notably, a novel subunit with an N-terminal “helix-turn-helix” motif embedded in the gap between the RC and the LH ring is identified. The purified RC-LH1 complex exhibits high stability in solutions containing Mg2+ or Ca2+. The periplasmic Cyt c2 is predicted to bind at the junction between the Cyt subunit and the membrane plane, enabling electron transfer from Cyt c2 to the proximal heme of the tri-heme Cyt, and subsequently to the special pair of bacteriochlorophylls. These findings provide structural insights into the efficient energy and electron transfer processes within a distinct type of RC-LH1, and shed light on evolutionary adaptations of photosynthesis. en-copyright= kn-copyright= en-aut-name=WangWeiwei en-aut-sei=Wang en-aut-mei=Weiwei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LiuYanting en-aut-sei=Liu en-aut-mei=Yanting kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GuJiayi en-aut-sei=Gu en-aut-mei=Jiayi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AnShaoya en-aut-sei=An en-aut-mei=Shaoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaCheng en-aut-sei=Ma en-aut-mei=Cheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GaoHaichun en-aut-sei=Gao en-aut-mei=Haichun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=JiaoNianzhi en-aut-sei=Jiao en-aut-mei=Nianzhi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=BeattyJohn Thomas en-aut-sei=Beatty en-aut-mei=John Thomas kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KoblížekMichal en-aut-sei=Koblížek en-aut-mei=Michal kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ZhangXing en-aut-sei=Zhang en-aut-mei=Xing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ZhengQiang en-aut-sei=Zheng en-aut-mei=Qiang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=ChenJing‐Hua en-aut-sei=Chen en-aut-mei=Jing‐Hua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=College of Life Sciences, Zhejiang University kn-affil= affil-num=2 en-affil=State Key Laboratory of Marine Environmental Science, College of Ocean and Earth Sciences, Xiamen University kn-affil= affil-num=3 en-affil=College of Life Sciences, Zhejiang University kn-affil= affil-num=4 en-affil=Department of Pathology of Sir Run Run Shaw Hospital, Department of Biophysics, Zhejiang University School of Medicine kn-affil= affil-num=5 en-affil=Department of Pathology of Sir Run Run Shaw Hospital, Department of Biophysics, Zhejiang University School of Medicine kn-affil= affil-num=6 en-affil=College of Life Sciences, Zhejiang University kn-affil= affil-num=7 en-affil=State Key Laboratory of Marine Environmental Science, College of Ocean and Earth Sciences, Xiamen University kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, and Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Department of Microbiology & Immunology, University of British Columbia kn-affil= affil-num=10 en-affil=Laboratory of Anoxygenic Phototrophs, Institute of Microbiology, Czech Academy of Science kn-affil= affil-num=11 en-affil=Department of Pathology of Sir Run Run Shaw Hospital, Department of Biophysics, Zhejiang University School of Medicine kn-affil= affil-num=12 en-affil=State Key Laboratory of Marine Environmental Science, College of Ocean and Earth Sciences, Xiamen University kn-affil= affil-num=13 en-affil=College of Life Sciences, Zhejiang University kn-affil= en-keyword=energy transfer kn-keyword=energy transfer en-keyword=photoheterotrophic bacteria kn-keyword=photoheterotrophic bacteria en-keyword=photosynthesis kn-keyword=photosynthesis en-keyword=reaction center kn-keyword=reaction center en-keyword=structure kn-keyword=structure 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=20250418 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Innovations in paper-based analytical devices and portable absorption photometers for onsite analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Two types of analytical instruments and devices—one sophisticated high-performance instrument and another portable device—have been the focus of recent trends in analytical science. The necessity of point-of-care testing and onsite analysis has accelerated the advancement of high-performance, user-friendly portable analytical devices such as paper-based analytical devices (PADs) and light-emitting diode-based portable photometers. In this review, we summarize our achievements in the study of PADs and portable photometers. Several types of PADs are capable of performing titrations, metal ion analysis, and food analysis, while photometers, which consist of paired emitter–detector light-emitting diode (PEDD) photometers, are used for thiocyanate and herbicide analysis. These PADs and photometers permit the onsite determination of real environmental, body fluid, and food samples when an equipped laboratory is unavailable. 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=UmedaMika I. en-aut-sei=Umeda en-aut-mei=Mika I. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=RenJianchao en-aut-sei=Ren en-aut-mei=Jianchao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= affil-num=1 en-affil=Department of Chemistry, Faculty of Science and Technology, Thammasat University kn-affil= affil-num=2 en-affil=Department of Chemistry, Okayama University kn-affil= affil-num=3 en-affil=Department of Chemistry, Okayama University kn-affil= affil-num=4 en-affil=Department of Chemistry, Okayama University kn-affil= en-keyword=Point-of-care testing kn-keyword=Point-of-care testing en-keyword=Onsite analysis kn-keyword=Onsite analysis en-keyword=Paper-based analytical device kn-keyword=Paper-based analytical device en-keyword=Paired emitter–detector light-emitting diode kn-keyword=Paired emitter–detector light-emitting diode en-keyword=Photometer kn-keyword=Photometer en-keyword=Environmental analysis kn-keyword=Environmental analysis en-keyword=Food analysis kn-keyword=Food analysis END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=3 article-no= start-page=321 end-page=343 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=Physiological and Biochemical Traits of Dormancy Release and Growth Resumption in Japanese Cedar in the Warm-Temperate Zone en-subtitle= kn-subtitle= en-abstract= kn-abstract=Global warming will disturb dormancy release and growth resumption of trees. To better understand this process, it is important to investigate physiological and biochemical traits related to these stages. We examined dormancy release and growth resumption in Japanese cedar (Cryptomeria japonica [L.] D. Don), an evergreen needle-leaved tree, in the warm-temperate zone by evaluating budbreak under growth-promoting conditions, and simultaneously examining respiration rates and contents of carbohydrates and phytohormones in shoots from November 2022 to March 2023. A long time to budbreak and the lowest budbreak rates of 75% in November indicated shallow dormancy. Budbreak rates of 98%, short time to budbreak, and first appearance of budbreak in the field in March indicated growth resumption. Continuous changes in budbreak rates and time to budbreak between dormancy and growth resumption indicated dormancy was gradually released. Surges in budbreak rates in December indicated dormancy was almost completely released by early winter. Contents of abscisic acid (ABA) and salicylic acid (SA) decreased from November, remained low in March, and were strongly associated with budbreak rates according to principal component analysis. It was suggested that the depletion of SA led to the depletion of ABA, contributing to dormancy release and growth resumption. Fructose and trans-zeatin accumulated until February, and low levels of starch, indole-3-acetic acid, jasmonic acid, and jasmonic acid-isoleucine during winter was followed by accumulation in March. Although these biochemical traits were less related to budbreak rates compared to ABA and SA, they seemed to assist either dormancy release or growth resumption. en-copyright= kn-copyright= en-aut-name=HiejimaShoma en-aut-sei=Hiejima en-aut-mei=Shoma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SeinoHiroto en-aut-sei=Seino en-aut-mei=Hiroto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HachisukaRico en-aut-sei=Hachisuka en-aut-mei=Rico kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeYuka en-aut-sei=Watanabe en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsuuraTakakazu en-aut-sei=Matsuura en-aut-mei=Takakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MoriIzumi C. en-aut-sei=Mori en-aut-mei=Izumi C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UgawaShin en-aut-sei=Ugawa en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=The United Graduate School of Agricultural Sciences, Kagoshima University kn-affil= affil-num=2 en-affil=Graduate School of Agriculture, Forestry and Fisheries, Kagoshima University kn-affil= affil-num=3 en-affil=The United Graduate School of Agricultural Sciences, Kagoshima University kn-affil= affil-num=4 en-affil=Graduate School of Agriculture, Forestry and Fisheries, Kagoshima University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=The United Graduate School of Agricultural Sciences, Kagoshima University kn-affil= en-keyword=Japanese cedar kn-keyword=Japanese cedar en-keyword=Warm-temperate zone kn-keyword=Warm-temperate zone en-keyword=Dormancy release kn-keyword=Dormancy release en-keyword=Growth resumption kn-keyword=Growth resumption en-keyword=Physio-biochemical traits kn-keyword=Physio-biochemical traits END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=6 article-no= start-page=e70126 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sulphur‐Acquisition Pathways for Cysteine Synthesis Confer a Fitness Advantage to Bacteria in Plant Extracts en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bacteria and plants are closely associated with human society, in fields such as agriculture, public health, the food industry, and waste disposal. Bacteria have evolved nutrient-utilisation systems adapted to achieve the most efficient growth in their major habitats. However, empirical evidence to support the significance of bacterial nutrient utilisation in adaptation to plants is limited. Therefore, we investigated the genetic and nutritional factors required for bacterial growth in plant extracts by screening an Escherichia coli gene-knockout library in vegetable-based medium. Mutants lacking genes involved in sulphur assimilation, whereby sulphur is transferred from sulphate to cysteine, exhibited negligible growth in vegetable-based medium or plant extracts, owing to the low cysteine levels. The reverse transsulphuration pathway from methionine, another pathway for donating sulphur to cysteine, occurring in bacteria such as Bacillus subtilis, also played an important role in growth in plant extracts. These two sulphur-assimilation pathways were more frequently observed in plant-associated than in animal-associated bacteria. Sulphur-acquisition pathways for cysteine synthesis thus play a key role in bacterial growth in plant-derived environments such as plant residues and plant exudates. en-copyright= kn-copyright=

The cases of 98 patients treated with chemo + IO were prospectively collected and analyzed for effectiveness and safety. The response rate to chemo + IO was 46.9%, and the disease control rate was 76.5%. The median progression-free survival and overall survival (OS) in the total population were 5.2 and 22.3 months, respectively. The patients positive for PD-L1 (≥ 1%) showed significantly longer OS than the negative group (<1%) (median 26.7 vs. 18.7 months, p=0.04). Pre-existing interstitial lung disease (ILD) was associated with shorter OS than the absence of ILD (median 9.0 vs. 22.6 months, p<0.01). Immunerelated adverse events (irAEs) were observed in 28 patients (28.6%). The most frequent irAE was ILD (n=11); Grade 1 (n=1 patient), G2 (n=5), G3 (n=4), and only a single patient with a G5 irAE. In this CS-Lung-003 study, first-line chemo + IO in a real-world setting showed good effectiveness, comparable to that observed in international clinical trials. In real-world practice, chemo + IO is a promising and steadfast strategy. en-copyright= kn-copyright= en-aut-name=KanajiNobuhiro en-aut-sei=Kanaji en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiiKazuya en-aut-sei=Nishii en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsubataYukari en-aut-sei=Tsubata en-aut-mei=Yukari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakaoMika en-aut-sei=Nakao en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkunoTakae en-aut-sei=Okuno en-aut-mei=Takae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkawaSachi en-aut-sei=Okawa en-aut-mei=Sachi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakataKenji en-aut-sei=Takata en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KodaniMasahiro en-aut-sei=Kodani en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamasakiMasahiro en-aut-sei=Yamasaki en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujitakaKazunori en-aut-sei=Fujitaka en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KubotaTetsuya en-aut-sei=Kubota en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=InoueMasaaki en-aut-sei=Inoue en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=WatanabeNaoki en-aut-sei=Watanabe en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 ORCID= en-aut-name=CS-Lung-003 Investigator en-aut-sei=CS-Lung-003 Investigator en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Internal Medicine, Division of Hematology, Rheumatology and Respiratory Medicine, Faculty of Medicine, Kagawa University kn-affil= affil-num=2 en-affil=Department of Respiratory Medicine, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=3 en-affil=Department of Internal Medicine, Division of Medical Oncology and Respiratory Medicine, Shimane University Faculty of Medicine kn-affil= affil-num=4 en-affil=Department of Internal Medicine, Division of Medical Oncology and Respiratory Medicine, Shimane University Faculty of Medicine kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Division of Medical Oncology and Respiratory Medicine, Shimane University Faculty of Medicine kn-affil= affil-num=6 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Division of Medical Oncology and Molecular Respirology, Faculty of Medicine, Tottori University kn-affil= affil-num=9 en-affil=Department of Respiratory Disease, Hiroshima Red Cross Hospital and Atomic-Bomb Survivors Hospital kn-affil= affil-num=10 en-affil=Department of Molecular and Internal Medicine, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=11 en-affil=Department of Respiratory Medicine and Allergology, Kochi University kn-affil= affil-num=12 en-affil=Department of Chest Surgery, Shimonoseki City Hospital kn-affil= affil-num=13 en-affil=Department of Internal Medicine, Division of Hematology, Rheumatology and Respiratory Medicine, Faculty of Medicine, Kagawa University kn-affil= affil-num=14 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=15 en-affil= kn-affil= en-keyword=non-small cell lung cancer kn-keyword=non-small cell lung cancer en-keyword=real-world kn-keyword=real-world en-keyword=first-line kn-keyword=first-line en-keyword=immune checkpoint inhibitor kn-keyword=immune checkpoint inhibitor en-keyword=combined immunotherapy kn-keyword=combined immunotherapy END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=9 article-no= start-page=1559 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impacts of Dental Follicle Cells and Periodontal Ligament Cells on the Bone Invasion of Well-Differentiated Oral Squamous Cell Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Oral squamous cell carcinoma (OSCC) frequently invades the jawbone, leading to diagnostic and therapeutic challenges. While tumor-bone interactions have been studied, the specific roles of dental follicle cells (DFCs) and periodontal ligament cells (PDLCs) in OSCC-associated bone resorption remain unclear. This study aimed to compare the effects of DFCs and PDLCs on OSCC-induced bone invasion and elucidate the underlying mechanisms. Methods: Primary human DFCs and PDLCs were isolated from extracted third molars and characterized by Giemsa and immunofluorescence staining. An in vitro co-culture system and an in vivo xenograft mouse model were established using the HSC-2 OSCC cell line. Tumor invasion and osteoclast activation were assessed by hematoxylin and eosin (HE) and tartrate-resistant acid phosphatase (TRAP) staining. Immunohistochemical analysis was performed to evaluate the expression of receptor activator of NF-kappa B ligand (RANKL) and parathyroid hormone-related peptide (PTHrP). Results: DFCs significantly enhanced OSCC-induced bone resorption by promoting osteoclastogenesis and upregulating RANKL and PTHrP expression. In contrast, PDLCs suppressed RANKL expression and partially modulated PTHrP levels, thereby reducing osteoclast activity. Conclusions: DFCs and PDLCs exert opposite regulatory effects on OSCC-associated bone destruction. These findings underscore the importance of stromal heterogeneity and highlight the therapeutic potential of targeting specific stromal-tumor interactions to mitigate bone-invasive OSCC. en-copyright= kn-copyright= en-aut-name=ChangAnqi en-aut-sei=Chang en-aut-mei=Anqi 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=PiaoTianyan en-aut-sei=Piao en-aut-mei=Tianyan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ArashimaTakuma en-aut-sei=Arashima en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=EainHtoo Shwe en-aut-sei=Eain en-aut-mei=Htoo Shwe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SoeYamin en-aut-sei=Soe en-aut-mei=Yamin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MinZin Zin en-aut-sei=Min en-aut-mei=Zin Zin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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=10 ORCID= affil-num=1 en-affil=Department of Oral Pathology and Medicine, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral Pathology and Medicine, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Pathology and Medicine, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Pathology and Medicine, Okayama University kn-affil= affil-num=5 en-affil=Department of Oral Pathology and Medicine, Okayama University kn-affil= affil-num=6 en-affil=Department of Oral Pathology and Medicine, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral Pathology and Medicine, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral Pathology and Medicine, Okayama University kn-affil= affil-num=9 en-affil=Department of Oral Pathology and Medicine, Okayama University kn-affil= affil-num=10 en-affil=Department of Oral Pathology and Medicine, Okayama University kn-affil= en-keyword=oral squamous cell carcinoma kn-keyword=oral squamous cell carcinoma en-keyword=dental follicle cells kn-keyword=dental follicle cells en-keyword=periodontal ligament cells kn-keyword=periodontal ligament cells en-keyword=bone invasion kn-keyword=bone invasion en-keyword=receptor activator of NF-kappa B ligand kn-keyword=receptor activator of NF-kappa B ligand en-keyword=parathyroid hormone-related peptide kn-keyword=parathyroid hormone-related peptide END start-ver=1.4 cd-journal=joma no-vol=214 cd-vols= no-issue= article-no= start-page=32 end-page=41 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Medaka approach to evolutionary social neuroscience en-subtitle= kn-subtitle= en-abstract= kn-abstract=Previously, the integration of comparative biological and neuroscientific approaches has led to significant advancements in social neuroscience. This review highlights the potential and future directions of evolutionary social neuroscience research utilizing medaka fishes (the family Adrianichthyidae) including Japanese medaka (Oryzias latipes). We focus on medaka social cognitive capabilities and mate choice behavior, particularly emphasizing mate preference using visual cues. Medaka fishes are also advantageous due to their abundant genetic resources, extensive genomic information, and the relative ease of laboratory breeding and genetic manipulation. Here we present some research examples of both the conventional neuroscience approach and evolutionary approach involving medaka fishes and other species. We also discuss the prospects of uncovering the molecular and cellular mechanisms underlying the diversity of visual mate preference among species. Especially, we introduce that the single-cell transcriptome technology, particularly in conjunction with 'Adaptive Circuitry Census', is an innovative tool that bridges comparative biological methods and neuroscientific approaches. Evolutionary social neuroscience research using medaka has the potential to unveil fundamental principles in neuroscience and elucidate the mechanisms responsible for generating diversity in mating strategies. en-copyright= kn-copyright= en-aut-name=AnsaiSatoshi en-aut-sei=Ansai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Hiraki-KajiyamaTowako en-aut-sei=Hiraki-Kajiyama en-aut-mei=Towako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UedaRyutaro en-aut-sei=Ueda en-aut-mei=Ryutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SekiTakahide en-aut-sei=Seki en-aut-mei=Takahide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YokoiSaori en-aut-sei=Yokoi en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatsumuraTakafumi en-aut-sei=Katsumura en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakeuchiHideaki en-aut-sei=Takeuchi en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Ushimado Marine Institute, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Life Sciences, Tohoku University kn-affil= affil-num=3 en-affil=Graduate School of Life Sciences, Tohoku University kn-affil= affil-num=4 en-affil=Graduate School of Life Sciences, Tohoku University kn-affil= affil-num=5 en-affil=School of Pharmaceutical Sciences, Hokkaido University kn-affil= affil-num=6 en-affil=School of Medicine, Kitasato University kn-affil= affil-num=7 en-affil=Graduate School of Life Sciences, Tohoku University kn-affil= en-keyword=Evolutionary neuroscience kn-keyword=Evolutionary neuroscience en-keyword=Comparative neuroscience kn-keyword=Comparative neuroscience en-keyword=Medaka bioresource kn-keyword=Medaka bioresource en-keyword=Visual mate preference kn-keyword=Visual mate preference en-keyword=Sexual selection kn-keyword=Sexual selection en-keyword=Genetic manipulation kn-keyword=Genetic manipulation END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=93 end-page=100 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=Lower Work Engagement Is Associated with Insomnia, Psychological Distress, and Neck Pain among Junior and Senior High School Teachers in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=School teachers are subject to both physical and mental health problems. We examined cross-sectional relationships between work engagement and major health outcomes among junior and senior high school teachers in Japan via a nationwide survey in 2019-2020. A total of 3,160 respondents were included in the analyses (19.9% response rate). Work engagement was assessed with the Utrecht Work Engagement Scale-9 (UWES-9), and we thus divided the teachers into quartiles according to their UWES-9 scores. Based on validated questionnaires, we assessed insomnia, psychological distress, and neck pain as health outcomes. A binomial logistic regression adjusted for age, gender, school type, teacher’s roles, involvement in club activities, division of duties, employment status, and whether they lived with family demonstrated that the teachers with lower UWES-9 scores had higher burdens of insomnia, psychological distress, and neck pain (odds ratios [95% confidence intervals] in 4th vs. 1st quartile, 2.92 (2.34-3.65), 3.70 (2.81-4.88), and 2.12 (1.68-2.68), respectively; all trend p<0.001). There were no significant differences in these associations between full-time and part-time teachers. Our findings indicate that low work engagement may contribute to physical and mental health issues among junior and senior high school teachers, thus providing insights for preventing health problems in this profession. en-copyright= kn-copyright= en-aut-name=TsuchieRina en-aut-sei=Tsuchie en-aut-mei=Rina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukudaMari en-aut-sei=Fukuda en-aut-mei=Mari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsumuraHideki en-aut-sei=Tsumura en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KinutaMinako en-aut-sei=Kinuta en-aut-mei=Minako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HisamatsuTakashi en-aut-sei=Hisamatsu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KandaHideyuki en-aut-sei=Kanda en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Psychology, Graduate School of Technology, Industrial and Social Sciences, Tokushima University kn-affil= affil-num=4 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=work engagement kn-keyword=work engagement en-keyword=school teachers kn-keyword=school teachers en-keyword=insomnia kn-keyword=insomnia en-keyword=psychological distress kn-keyword=psychological distress en-keyword=neck pain kn-keyword=neck pain END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue=1 article-no= start-page=1 end-page=28 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=Inseparable Gauss maps and dormant opers en-subtitle= kn-subtitle= en-abstract= kn-abstract=The present paper aims to generalize a result by H. Kaji on Gauss maps in positive characteristic and establish an interaction with the study of dormant opers and Frobenius-projective structures. We prove a correspondence between dormant opers on a smooth projective variety and closed immersions into a projective space with purely inseparable Gauss map. By using this, we determine the subfields of the function field of a smooth curve in positive characteristic induced by Gauss maps. Moreover, this correspondence gives us a Frobenius-projective structure on a Fermat hypersurface. en-copyright= kn-copyright= en-aut-name=WakabayashiYasuhiro en-aut-sei=Wakabayashi en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Information Science and Technology, Osaka University kn-affil= en-keyword=Gauss map kn-keyword=Gauss map en-keyword=Frobenius-projective structure kn-keyword=Frobenius-projective structure en-keyword=dormant kn-keyword=dormant en-keyword=indigenous bundle kn-keyword=indigenous bundle en-keyword=oper kn-keyword=oper END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=7506 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A glucocorticoid-regulating molecule, Fkbp5, may interact with mitogen-activated protein kinase signaling in the organ of Corti of mice cochleae en-subtitle= kn-subtitle= en-abstract= kn-abstract=FKBP5 is a 51-Da FK506-binding protein and member of the immunophilin family involved in controlling the signaling of glucocorticoid receptor from the cytosol to nucleus. Fkbp5 has previously been shown to be expressed in murine cochlear tissue, including the organ of Corti (i.e., the sensory epithelium of the cochlea). Fkbp5-/- mice as used in this study show hearing loss in the low-frequency (8-kHz) range and click-evoked auditory brainstem response (ABR) threshold compared to wild-type mice. Both Fkbp5-/- and wild-type mice showed hearing loss at all frequencies and click-ABR thresholds at 24 h and 14 days following acoustic overexposure (AO). Tissues of the organ of Corti were subjected to RNA sequencing and KEGG pathway analysis. In Fkbp5-/- mice before AO, the mitogen-activated protein kinase (MAPK) signaling pathway was dysregulated compared to wild-type mice. In wild-type mice at 12 h following AO, the most significantly modulated KEGG pathway was the TNF signaling pathway and major MAPK molecules p38 and Jun were involved in the TNF signaling pathway. In Fkbp5-/- mice at 12 h following AO, the MAPK signaling pathway was dysregulated compared to wild-type mice following AO. In conclusion, Fkbp5 interacts with MAPK signaling in the organ of Corti in mice cochleae. en-copyright= kn-copyright= en-aut-name=SatoAsuka en-aut-sei=Sato en-aut-mei=Asuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OmichiRyotaro en-aut-sei=Omichi en-aut-mei=Ryotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaedaYukihide en-aut-sei=Maeda en-aut-mei=Yukihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AndoMizuo en-aut-sei=Ando en-aut-mei=Mizuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=The organ of Corti kn-keyword=The organ of Corti en-keyword=Acoustic trauma kn-keyword=Acoustic trauma en-keyword=RNA sequencing kn-keyword=RNA sequencing en-keyword=51-Da FK506-binding protein kn-keyword=51-Da FK506-binding protein en-keyword=Mitogen-activated protein kinase signaling kn-keyword=Mitogen-activated protein kinase signaling en-keyword=Tumor necrosis factor signaling kn-keyword=Tumor necrosis factor signaling END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=4 article-no= start-page=1391 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250219 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Course of General Fatigue in Patients with Post-COVID-19 Conditions Who Were Prescribed Hochuekkito: A Single-Center Exploratory Pilot Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: After the start of the COVID-19 pandemic, general fatigue in patients with long COVID and post-COVID-19 conditions (PCC) became a medical issue. Although there is a lack of evidence-based treatments, Kampo medicine (traditional Japanese medicine) has gained attention in Japan. At an outpatient clinic in Japan specializing in long COVID, 24% of all prescriptions were Kampo medicines, and 72% of Kampo medicine prescriptions were hochuekkito. However, there has been no prospective, quantitative study on the course of fatigue in patients with long COVID and PCC who were prescribed hochuekkito. The aim of this study was to clarify the course of fatigue in those patients. Methods: This study included patients aged 18 years or older with general fatigue who visited the long COVID specialized outpatient clinic at Okayama University Hospital and consented to participate after being prescribed hochuekkito. We reviewed the backgrounds of the patients, and we evaluated the patients' fatigue assessment scale in person or online. Results: Twenty patients were enrolled in this study from September to December in 2023. The average age of the patients was 42.9 years (SD: 15.8 years) and 12 patients (60%) were female. After hochuekkito administration, the fatigue assessment scale score decreased from 35.9 (SD: 5.9) at the initial visit to 31.2 (SD: 9.4) after 8 weeks, indicating a trend for improvement in fatigue (difference: 4.7; 95% CI: 0.5-8.9). Conclusions: A trend for improvement in fatigue was observed in patients with long COVID and PCC who were prescribed hochuekkito, indicating a potential benefit of hochuekkito for general fatigue in such patients. General fatigue in patients with long COVID or PCC can be classified as post-infectious fatigue syndrome and is considered a condition of qi deficiency in Kampo medicine, for which hochuekkito is appropriately indicated. en-copyright= kn-copyright= en-aut-name=TokumasuKazuki en-aut-sei=Tokumasu en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsukiNobuyoshi en-aut-sei=Matsuki en-aut-mei=Nobuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakamotoYoko en-aut-sei=Sakamoto en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UedaKeigo en-aut-sei=Ueda en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsudaYui en-aut-sei=Matsuda en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakuradaYasue en-aut-sei=Sakurada en-aut-mei=Yasue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HondaHiroyuki en-aut-sei=Honda en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HasegawaToru en-aut-sei=Hasegawa en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TakaseRyosuke en-aut-sei=Takase en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OmuraDaisuke en-aut-sei=Omura en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=13 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=fatigue assessment scale (FAS) kn-keyword=fatigue assessment scale (FAS) en-keyword= general fatigue kn-keyword= general fatigue en-keyword= hochuekkito kn-keyword= hochuekkito en-keyword= kampo medicine kn-keyword= kampo medicine en-keyword= long COVID kn-keyword= long COVID en-keyword= post-COVID-19 condition kn-keyword= post-COVID-19 condition END start-ver=1.4 cd-journal=joma no-vol=96 cd-vols= no-issue=10 article-no= start-page=1241 end-page=1252 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210728 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Validated international definition of the thrombocytopenia, anasarca, fever, reticulin fibrosis, renal insufficiency, and organomegaly clinical subtype (TAFRO) of idiopathic multicentric Castleman disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Thrombocytopenia, anasarca, fever, reticulin fibrosis, renal insufficiency, and organomegaly (TAFRO) syndrome is a heterogeneous entity manifesting with a constellation of symptoms described above that can occur in the context of idiopathic multicentric Castleman disease (iMCD) as well as infectious diseases, malignancies, and rheumatologic disorders. So, iMCD-TAFRO is an aggressive subtype of iMCD with TAFRO syndrome and often hyper-vascularized lymph nodes. Since we proposed diagnostic criteria of iMCD-TAFRO in 2016, we have accumulated new insights on the disorder and additional cases have been reported worldwide. In this systematic review and cohort analysis, we established and validated a definition for iMCD-TAFRO. First, we searched PubMed and Japan Medical Abstracts Society databases using the keyword “TAFRO” to extract cases. Patients with possible systemic autoimmune diseases and hematologic malignancies were excluded. Our search identified 54 cases from 50 articles. We classified cases into three categories: (1) iMCD-TAFRO (TAFRO syndrome with lymph node histopathology consistent with iMCD), (2) possible iMCD-TAFRO (TAFRO syndrome with no lymph node biopsy performed and no other co-morbidities), and (3) TAFRO without iMCD or other co-morbidities (TAFRO syndrome with lymph node histopathology not consistent with iMCD or other comorbidities). Based on the findings, we propose an international definition requiring four clinical criteria (thrombocytopenia, anasarca, fever/hyperinflammatory status, organomegaly), renal dysfunction or characteristic bone marrow findings, and lymph node features consistent with iMCD. The definition was validated with an external cohort (the ACCELERATE Natural History Registry). The present international definition will facilitate a more precise and comprehensive approach to the diagnosis of iMCD-TAFRO. en-copyright= kn-copyright= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FajgenbaumDavid C. en-aut-sei=Fajgenbaum en-aut-mei=David C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=PiersonSheila K. en-aut-sei=Pierson en-aut-mei=Sheila K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IwakiNoriko en-aut-sei=Iwaki en-aut-mei=Noriko 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=KawanoMitsuhiro en-aut-sei=Kawano en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraNaoya en-aut-sei=Nakamura en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IzutsuKoji en-aut-sei=Izutsu en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakeuchiKengo en-aut-sei=Takeuchi en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NishimuraMidori Filiz en-aut-sei=Nishimura en-aut-mei=Midori Filiz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=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= en-aut-name=YoshizakiKazuyuki en-aut-sei=Yoshizaki en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=OksenhendlerEric en-aut-sei=Oksenhendler en-aut-mei=Eric kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=van RheeFrits en-aut-sei=van Rhee en-aut-mei=Frits kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 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=16 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=Center for Cytokine Storm Treatment & Laboratory, Division of Translational Medicine and Human Genetics, Perelman School of Medicine, University of Pennsylvania kn-affil= affil-num=3 en-affil=Center for Cytokine Storm Treatment & Laboratory, Division of Translational Medicine and Human Genetics, Perelman School of Medicine, University of Pennsylvania kn-affil= affil-num=4 en-affil=Hematology/Respiratory Medicine, Kanazawa University Graduate School of Medical Science 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 Rheumatology, Kanazawa University Graduate School of Medical Science kn-affil= affil-num=7 en-affil=Department of Pathology, Tokai University School of Medicine kn-affil= affil-num=8 en-affil=Department of Hematology, National Cancer Center Hospital kn-affil= affil-num=9 en-affil=Department of Pathology, The Cancer Institute Hospital of Japanese Foundation for Cancer Research kn-affil= affil-num=10 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Organic Fine Chemicals, Institute of Scientific and Industrial Research, Osaka University kn-affil= affil-num=14 en-affil=Department of Clinical Immunology, Hôpital Saint-Louis kn-affil= affil-num=15 en-affil=Myeloma Center, University of Arkansas for Medical Sciences kn-affil= affil-num=16 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= 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 𝑑-wave altermagnets and 𝑝-wave magnets. We find that the Andreev bound states in 𝑑-wave altermagnet and 𝑝𝑦-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 𝜑. In contrast, the Andreev bound states for 𝑝𝑥-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 𝑑𝑥2−𝑦2- and 𝑝-wave magnet junctions are prone to host zero energy peaks. While the zero-energy peak in 𝑑𝑥2−𝑦2-wave altermagnet junctions tends to oscillate with the magnetic order, it remains robust in 𝑝-wave magnet junctions. We then discover that the Josephson current in 𝑑-wave altermagnet junctions is composed of higher harmonics of 𝜑, which originate a 𝜙-Josephson junction behavior entirely controlled by the magnetic order in 𝑑𝑥⁢𝑦-wave altermagnets. In contrast, the Josephson current in Josephson junctions with 𝑝-wave magnets exhibits a conventional sinelike profile with a fast sign change at 𝜑=𝜋 due to zero-energy Andreev bound states. We also demonstrate that the critical currents in 𝑑-wave altermagnet Josephson junctions exhibit an oscillatory decay with the increase of the magnetic order, while the oscillations are absent in 𝑝-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 𝑑-wave altermagnets and 𝑝-wave magnets originates from odd-frequency spin-triplet 𝑠-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=74 cd-vols= no-issue=3 article-no= start-page=96 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=Cancer-associated fibroblasts promote pro-tumor functions of neutrophils in pancreatic cancer via IL-8: potential suppression by pirfenidone en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background The mechanisms by which neutrophils acquire pro-tumor properties remain poorly understood. In pancreatic cancer, cancer-associated fibroblasts (CAFs) may interact with neutrophils, directing them to promote tumor progression.
Methods To validate the association between CAFs and neutrophils, the localization of neutrophils was examined in clinically resected pancreatic cancer specimens. CAFs were produced by culturing in cancer-conditioned media, and the effects of these CAFs on neutrophils were examined. In vitro migration and invasion assays assess the effect of CAF-activated neutrophils on cancer cells. The factors secreted by the activated neutrophils were also explored. Finally, pirfenidone (PFD) was tested to determine whether it could suppress the pro-tumor functions of activated neutrophils.
Results In pancreatic cancer specimens, neutrophils tended to co-localize with IL-6-positive CAFs. Neutrophils co-cultured with CAFs increased migratory capacity and prolonged life span. CAF-affected neutrophils enhance the migratory and invasive activities of pancreatic cancer cells. IL-8 is the most upregulated cytokine secreted by the neutrophils. PFD suppresses IL-8 secretion from CAF-stimulated neutrophils and mitigates the malignant traits of pancreatic cancer cells.
Conclusion CAFs activate neutrophils and enhance the malignant phenotype of pancreatic cancer. The interactions between cancer cells, CAFs, and neutrophils can be disrupted by PFD, highlighting a potential therapeutic approach. en-copyright= kn-copyright= en-aut-name=YagiTomohiko

Methods: Overall, 179 patients were categorized into LWI use (LWI group, 90 patients) and nonuse (control group, 89 patients) groups. Patients in the LWI group were instructed to wear an LWI from the initiation of load bearing up to 3 months postoperatively. Medial meniscus extrusion (MME) was evaluated preoperatively and 1 year postoperatively, Kellgren–Lawrence (KL) grade and clinical scores were evaluated preoperatively and 2 years postoperatively, and second-look arthroscopic meniscal healing scores were evaluated at 1 year postoperatively.
Results: The proportion of patients with KL grade progression at 2 years postoperatively was significantly lower in the LWI group than in the control group (23.3% vs. 39.3%; p = 0.024). Change in the MME at 1 year postoperatively was significantly smaller in the LWI group than in the control group (1.1 ± 1.2 vs. 1.6 ± 1.4 mm; p = 0.042). The Lysholm score (p = 0.003) and Knee Injury and Osteoarthritis Outcome Scores-sport and recreation function (p = 0.027) at 2 years postoperatively were significantly superior in the LWI group than in the control group. The arthroscopic meniscal healing score after 1 year was not significantly different between the LWI and control groups (total score, 7.6 ± 1.1 vs. 7.4 ± 1.3 points; p = 0.732). The anteroposterior width of the repaired posterior root at 1 year second-look evaluation was significantly broader in the LWI group than in the control group (7.7 ± 1.6 vs. 6.9 ± 1.6 mm; p = 0.001).
Conclusions: The use of LWI is an effective way to delay postoperative osteoarthritis progression and improve clinical outcomes after MMPR repair.

Dyslipidemia is a key focus of cardiovascular therapy and is characterized by hypertriglyceridemia mainly caused by lipoprotein lipase-mediated metabolism of ApoC-III in patients with ESRD. Pemafbrate, a selective peroxisome proliferator-activated receptor alpha modulator, can be used regardless of renal function and inhibit ApoC-III expression in the liver.
Case presentation We reported the cases of four patients on hemodialysis who met at least 175 mg/dL of triglycerides on the consecutive three tests between September 2022 and November 2022 and took 0.1 mg pemafbrate twice a day from November 2022 to May 2023. They experienced no adverse events after pemafbrate treatment. Pemafbrate signifcantly reduced triglyceride (TG) (302±72 to 140±50 mg/dL, p=0.048), total cholesterol (187±34 to 156±48 mg/dL, p=0.025), and Apo C-III (15.9±8.2 to 12.6±7.1, p=0.030) levels. Apo A-II levels signifcantly increased after treatment (27.0±6.1 to 37.1±5.8, p=0.041).
Conclusions Pemafbrate decreased TG, total cholesterol, and Apo-CIII and increased Apo A-II without adverse events. Further study is needed to examine the favorable efects of pemafbrate on the risk of CVD. en-copyright= kn-copyright= en-aut-name=OkadaRino en-aut-sei=Okada en-aut-mei=Rino kn-aut-name= kn-aut-sei=

predisposing factor for determining arthroscopic treatments in partial medial meniscus posterior root tears en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Patients with partial medial meniscus posterior root tears (MMPRTs) sometimes require arthroscopic pullout repair because of their intolerable/repeated knee pains and continuous disturbance in gait during activities of daily living. However, the predisposing factors for future knee surgery in patients with partial MMPRTs remain unclear. We compared the findings of magnetic resonance imaging (MRI) between patients who underwent pullout repair and nonoperative management following partial MMPRTs.
Methods Twenty-five patients who required arthroscopic repair for partial MMPRTs and 23 patients who were managed nonoperatively were evaluated during a mean follow-up period of 27.1 months. Sex, age, height, body weight, body mass index, duration from onset to initial MRI, MRI findings, and medial meniscus (MM) extrusion were compared between the two groups. Linear regression analysis was used to assess the correlation between MM extrusion and duration from onset to MRI examination.
Results No significant differences were observed between the pullout repair and nonoperative management groups in terms of patient demographics and the positive ratio of MRI-based root tear signs. However, absolute MM extrusion in the pullout repair group (3.49 ± 0.82 mm) was larger than that in the nonoperative management group (2.48 ± 0.60 mm, P < 0.001). Extrusion of the MM (> 3 mm) was detected more frequently in the pullout repair group than in the nonoperative management group (P < 0.001). The odds ratio in the pullout repair and MM extrusion > 3 mm cases was 9.662. Linear regression analysis revealed a fair correlation between the duration from onset to MRI and MM extrusion only in the pullout repair group (0.462 mm/month increase in MM extrusion).
Conclusions This study demonstrated that more severe MM extrusions were observed in the pullout repair group than in the nonoperative management group. Major extrusion (> 3 mm) was also observed more in the pullout repair group than in the nonoperative group. Assessing MM extrusion and its severity can help determine a valid treatment for patients with partial MMPRTs.

Study design Retrospective clinical case series.
Methods We included 58 eyes of 29 patients with acquired strabismus and high myopia (mean age ± standard deviation: 60.2 ± 14.7 years, axial length [AL]: 28.69 ± 2.12 mm). For all eyes, the equatorial diameter of the globe/AL ratio (EAR) and the globe/orbit volume ratio (GOR) were measured using MRI. EAR and GOR values were compared between the following groups: 9 men vs. 20 women; 8 younger (< 56 years) vs. 21 older (≥ 56 years) patients; and non-esotropia strabismus (NES: 7 patients) vs. esotropia (ET: 13 patients) vs. restrictive strabismus (RS: 9 patients) groups.
Results Female patients had a smaller EAR (0.87 ± 0.07) and larger GOR (0.38 ± 0.04) than male patients (0.92 ± 0.05 and 0.35 ± 0.03, both P < 0.01). Older patients had a smaller EAR (0.87 ± 0.07) than younger ones (0.93 ± 0.04, P < 0.01), without significant differences in GOR. EAR (NES: 0.92 ± 0.06, ET: 0.86 ± 0.06, RS: 0.89 ± 0.09) significantly differed among the three strabismus groups (P = 0.02: post-hoc test: NES vs. ET, P = 0.02; NES vs. RS, P = 0.49; RS vs. ET, P = 0.67), but no significant differences in GOR were found (P = 0.12).
Conclusions Among patients with acquired strabismus and high myopia, women, older patients, and those with esotropia exhibit a smaller EAR and longer sphere shape with AL as the major axis. The parameter EAR might be useful for evaluating the pathogenesis of strabismus associated with high myopia. en-copyright= kn-copyright= en-aut-name=KonoReika en-aut-sei=Kono en-aut-mei=Reika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamasakiIchiro en-aut-sei=Hamasaki en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KishimotoFumiko en-aut-sei=Kishimoto en-aut-mei=Fumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShimizuTakehiro en-aut-sei=Shimizu en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KindoHiroya en-aut-sei=Kindo en-aut-mei=Hiroya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShibataKiyo en-aut-sei=Shibata en-aut-mei=Kiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MorisawaShin en-aut-sei=Morisawa en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MorizaneYuki en-aut-sei=Morizane en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Division of Ophthalmology, Ibara City Hospital kn-affil= affil-num=4 en-affil=Division of Ophthalmology, Okayama City Hospital kn-affil= affil-num=5 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=High myopia kn-keyword=High myopia en-keyword=Strabismus kn-keyword=Strabismus en-keyword=Eye dimensions kn-keyword=Eye dimensions en-keyword=Magnetic resonance imaging kn-keyword=Magnetic resonance imaging en-keyword=Esotropia kn-keyword=Esotropia 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=78 cd-vols= no-issue=5 article-no= start-page=401 end-page=405 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pediatric Severe Febrile Thrombocytopenia Syndrome: A Case Report and Literature Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Severe febrile thrombocytopenia syndrome (SFTS) is a tick-borne infectious disease that is endemic in parts of eastern Asia. Few pediatric cases have been reported. We describe a case of SFTS in a seven-year-old girl who presented with prolonged fever and gastrointestinal symptoms. Leukopenia and thrombocytopenia on hematology, and a history of outdoor activity led us to diagnose SFTS, although the patient had no tick bite marks. We also review the literature and discuss the characteristics of pediatric SFTS. Physicians should consider SFTS in the differential diagnosis of fever with thrombocytopenia in children living in endemic areas. en-copyright= kn-copyright= en-aut-name=ToyotaYusuke en-aut-sei=Toyota en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UdaKazuhiro en-aut-sei=Uda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShirabeKomei en-aut-sei=Shirabe en-aut-mei=Komei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriwakeTadashi en-aut-sei=Moriwake en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Pediatrics, NHO Iwakuni Clinical Center kn-affil= affil-num=2 en-affil=Department of Pediatrics, NHO Iwakuni Clinical Center kn-affil= affil-num=3 en-affil=Yamaguchi Prefectural Institute of Public Health and Environment kn-affil= affil-num=4 en-affil=Department of Pediatrics, NHO Iwakuni Clinical Center kn-affil= en-keyword=child kn-keyword=child en-keyword=tick-borne disease kn-keyword=tick-borne disease en-keyword=severe febrile thrombocytopenia syndrome kn-keyword=severe febrile thrombocytopenia syndrome en-keyword=zoonoses kn-keyword=zoonoses END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=5 article-no= start-page=377 end-page=386 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prognostic Efficacy of the Albumin Grade in Patients with Hepatocellular Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=We previously found that “albumin grade”, formerly called the “ALBS grade,” demonstrated significant capability for prognostic stratification in hepatocellular carcinoma (HCC) patients treated with lenvatinib. The purpose of the present study was to compare the performance of the albumin grade with that of the modified albumin-bilirubin (mALBI) grade in predicting overall survival of HCC patients with different BCLC stages and treatment types. We enrolled 7,645 Japanese patients newly diagnosed with HCC using the Akaike information criteria (AIC), likelihood ratio, and C-index in different Barcelona Clinic Liver Cancer (BCLC) stages and treatments. The albumin grade showed similar and slightly better performance than the mALBI grade for BCLC stage 0 and A and especially for patients who underwent curative surgery and ablation. In patients treated with transcatheter arterial chemoembolization, molecular targeted agents, and the best supportive care, the mALBI grade had better performance than the albumin grade. However, the differences of the indices were very small in all scenarios. Overall, the albumin grade was comparable in efficacy to the mALBI grade, showing particular benefit for patients with early-stage HCC. en-copyright= kn-copyright= en-aut-name=HiranoYuichi

with adolescent idiopathic scoliosis (AIS) has focused on static postural control, with few studies assessing dynamic postural control. We aimed to identify factors affecting index of postural stability (IPS), a dynamic postural control parameter, in patients with AIS. The participants comprised 50 female patients with AIS. We measured the IPS using stabilometry to evaluate dynamic postural control ability. We investigated age of the participants, major curve position (thoracic or thoracolumbar/lumbar), Cobb angle, and coronal balance. We then assessed the relationships between stabilometry parameters and other variables. IPS was analyzed with a linear regression model. Coronal balance, major curve position, and age each correlated with dynamic postural control ability. The Cobb angle showed no correlation with any of the parameters. Our results offer new insights into the assessment of postural control in patients with AIS. en-copyright= kn-copyright= en-aut-name=YamawakiRyoko en-aut-sei=Yamawaki en-aut-mei=Ryoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OdaYoshiaki en-aut-sei=Oda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamaneShuhei en-aut-sei=Yamane en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MisawaHaruo en-aut-sei=Misawa en-aut-mei=Haruo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatayamaYoshimi en-aut-sei=Katayama en-aut-mei=Yoshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HamadaMasanori en-aut-sei=Hamada en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University kn-affil= affil-num=5 en-affil=Ryusoh Orthopaedic Hospital kn-affil= affil-num=6 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University kn-affil= affil-num=7 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University kn-affil= affil-num=8 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University kn-affil= en-keyword=adolescent idiopathic scoliosis kn-keyword=adolescent idiopathic scoliosis en-keyword=postural control kn-keyword=postural control en-keyword=coronal balance kn-keyword=coronal balance en-keyword=index of postural stability kn-keyword=index of postural stability en-keyword=stabilometry kn-keyword=stabilometry END start-ver=1.4 cd-journal=joma no-vol=137 cd-vols= no-issue=9 article-no= start-page=212 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mutations in starch BRANCHING ENZYME 2a suppress the traits caused by the loss of ISOAMYLASE1 in barley en-subtitle= kn-subtitle= en-abstract= kn-abstract=The genetic interactions among starch biosynthesis genes can be exploited to alter starch properties, but they remain poorly understood due to the various combinations of mutations to be tested. Here, we isolated two novel barley mutants defective in starch BRANCHING ENZYME 2a (hvbe2a-1 and hvbe2a-2) based on the starch granule (SG) morphology. Both hvbe2a mutants showed elongated SGs in the endosperm and increased resistant starch content. hvbe2a-1 had a base change in HvBE2a gene, substituting the amino acid essential for its enzyme activity, while hvbe2a-2 is completely missing HvBE2a due to a chromosomal deletion. Further genetic crosses with barley isoamylase1 mutants (hvisa1) revealed that both hvbe2a mutations could suppress defects in endosperm caused by hvisa1, such as reduction in starch, increase in phytoglycogen, and changes in the glucan chain length distribution. Remarkably, hvbe2a mutations also transformed the endosperm SG morphology from the compound SG caused by hvisa1 to bimodal simple SGs, resembling that of wild-type barley. The suppressive impact was in competition with floury endosperm 6 mutation (hvflo6), which could enhance the phenotype of hvisa1 in the endosperm. In contrast, the compound SG formation induced by the hvflo6 hvisa1 mutation in pollen was not suppressed by hvbe2a mutations. Our findings provide new insights into genetic interactions in the starch biosynthetic pathway, demonstrating how specific genetic alterations can influence starch properties and SG morphology, with potential applications in cereal breeding for desired starch properties. en-copyright= kn-copyright= en-aut-name=MatsushimaRyo en-aut-sei=Matsushima en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HisanoHiroshi en-aut-sei=Hisano en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=McNellyRose en-aut-sei=McNelly en-aut-mei=Rose kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OitomeNaoko F. en-aut-sei=Oitome en-aut-mei=Naoko F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SeungDavid en-aut-sei=Seung en-aut-mei=David kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujitaNaoko en-aut-sei=Fujita en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SatoKazuhiro en-aut-sei=Sato en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=John Innes Centre, Norwich Research Park kn-affil= affil-num=5 en-affil=Department of Biological Production, Akita Prefectural University kn-affil= affil-num=6 en-affil=John Innes Centre, Norwich Research Park kn-affil= affil-num=7 en-affil=Department of Biological Production, Akita Prefectural University kn-affil= affil-num=8 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=40 cd-vols= no-issue=32 article-no= start-page=16994 end-page=17000 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240730 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Droplet-Removal Processes on Fog-Harvesting Performance on Wettability-Controlled Wire Array with Staggered Arrangement en-subtitle= kn-subtitle= en-abstract= kn-abstract=Development of freshwater resources is vital to overcoming severe worldwide water scarcity. Fog harvesting has attracted attention as a candidate technology that can be used to obtain fresh water from a stream of foggy air without energy input. Drainage of captured droplets from fog harvesters is necessary to maintain the permeability of harp-shaped harvesters. In the present study, we investigated the effect of the droplet-removal process on the amount of water harvested using a harvester constructed by wettability-controlled wires with an alternating and staggered arrangement. Droplet transfer from hydrophobic to hydrophilic wires, located upstream and downstream of the fog flow, respectively, was observed with a fog velocity greater than 1.5 m/s. The proportion of harvesting resulting from droplet transfer exceeded 30% of the total, and it reflected more than 20% increase of the harvesting performance compared with that of a harvester with wires of the same wettability: this value varied with the adhesive property of the wires and fog velocity. Scaled-up and multilayered harvesters were developed to enhance harvesting performance. We demonstrated certain enhancements under multilayered conditions and obtained 15.99 g/30 min as the maximum harvested amount, which corresponds to 13.3% of the liquid contained in the fog stream and is enhanced by 10% compared with that without droplet transfer. en-copyright= kn-copyright= en-aut-name=YamadaYutaka en-aut-sei=Yamada en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkaJunya en-aut-sei=Oka en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IsobeKazuma en-aut-sei=Isobe en-aut-mei=Kazuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HoribeAkihiko en-aut-sei=Horibe en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=17591 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240730 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Training high-performance deep learning classifier for diagnosis in oral cytology using diverse annotations en-subtitle= kn-subtitle= en-abstract= kn-abstract=The uncertainty of true labels in medical images hinders diagnosis owing to the variability across professionals when applying deep learning models. We used deep learning to obtain an optimal convolutional neural network (CNN) by adequately annotating data for oral exfoliative cytology considering labels from multiple oral pathologists. Six whole-slide images were processed using QuPath for segmenting them into tiles. The images were labeled by three oral pathologists, resulting in 14,535 images with the corresponding pathologists' annotations. Data from three pathologists who provided the same diagnosis were labeled as ground truth (GT) and used for testing. We investigated six models trained using the annotations of (1) pathologist A, (2) pathologist B, (3) pathologist C, (4) GT, (5) majority voting, and (6) a probabilistic model. We divided the test by cross-validation per slide dataset and examined the classification performance of the CNN with a ResNet50 baseline. Statistical evaluation was performed repeatedly and independently using every slide 10 times as test data. For the area under the curve, three cases showed the highest values (0.861, 0.955, and 0.991) for the probabilistic model. Regarding accuracy, two cases showed the highest values (0.988 and 0.967). For the models using the pathologists and GT annotations, many slides showed very low accuracy and large variations across tests. Hence, the classifier trained with probabilistic labels provided the optimal CNN for oral exfoliative cytology considering diagnoses from multiple pathologists. These results may lead to trusted medical artificial intelligence solutions that reflect diverse diagnoses of various professionals. en-copyright= kn-copyright= en-aut-name=SukegawaShintaro en-aut-sei=Sukegawa en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaFuta en-aut-sei=Tanaka en-aut-mei=Futa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=HaraTakeshi en-aut-sei=Hara en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OchiaiTakanaga en-aut-sei=Ochiai en-aut-mei=Takanaga kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShimadaKatsumitsu en-aut-sei=Shimada en-aut-mei=Katsumitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=InoueYuta en-aut-sei=Inoue en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakiYoshihiro en-aut-sei=Taki en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakaiFumi en-aut-sei=Nakai en-aut-mei=Fumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakaiYasuhiro en-aut-sei=Nakai en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IshihamaTakanori en-aut-sei=Ishihama en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MiyazakiRyo en-aut-sei=Miyazaki en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MurakamiSatoshi en-aut-sei=Murakami en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 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=15 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 Electrical, Electronic and Computer Engineering, Faculty of Engineering, Gifu 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 Electrical, Electronic and Computer Engineering, Faculty of Engineering, Gifu University kn-affil= affil-num=5 en-affil=Division of Oral Pathogenesis and Disease Control, Department of Oral Pathology, Asahi University School of Dentistry kn-affil= affil-num=6 en-affil=Department of Oral Pathology, Graduate School of Oral Medicine, Matsumoto Dental University kn-affil= affil-num=7 en-affil=Department of Electrical, Electronic and Computer Engineering, Faculty of Engineering, Gifu University kn-affil= affil-num=8 en-affil=Department of Electrical, Electronic and Computer Engineering, Faculty of Engineering, Gifu University kn-affil= affil-num=9 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=10 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=11 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=12 en-affil=Stony Brook Cancer Center, Stony Brook University kn-affil= affil-num=13 en-affil=Department of Oral Pathology, Graduate School of Oral Medicine, Matsumoto Dental University kn-affil= affil-num=14 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=15 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Faculty of Medicine kn-affil= en-keyword=Deep learning kn-keyword=Deep learning en-keyword=Oral cytology kn-keyword=Oral cytology en-keyword=Classification kn-keyword=Classification en-keyword=Convolutional neural network kn-keyword=Convolutional neural network en-keyword=Probabilistic labeling kn-keyword=Probabilistic labeling END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=10 article-no= start-page=1594 end-page=1601 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240713 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Re-administration of platinum-based chemotherapy for recurrent endometrial cancer: an ancillary analysis of the SGSG-012/GOTIC-004/Intergroup study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background We previously demonstrated the applicability of the concept of “platinum sensitivity” in recurrent endometrial cancer. Although immune checkpoint inhibitors have been widely incorporated into endometrial cancer treatment, the debate continues regarding treatment options in patients with recurrent endometrial cancer who have previously received platinum-based chemotherapy. In this study, we assessed the duration of response to secondary platinum-based treatment using pooled data from the SGSG-012/GOTIC-004/Intergroup study.
Methods Among the 279 participants in the SGSG-012/GOTIC-004/Intergroup study wherein platinum-based chemotherapy was re-administered for managing recurrent endometrial cancer between January 2005 and December 2009, 130 (47%) responded to chemotherapy. We compared the relationship between platinum-free interval and duration of secondary platinum-based treatment using pooled data.
Results In 40 patients (31%), the duration of response to secondary platinum-based treatment exceeded the platinum-free interval. The duration of response to secondary platinum-based treatment exceeded 12 months in 51 patients (39%) [platinum-free interval: < 12 months, 14/48 (29%); 12–23 months, 18/43 (42%); 24–35 months, 8/19 (42%); ≥ 36 months, 11/20 (55%)]. In particular, in eight patients (6%), the duration of response to secondary platinum-based treatment exceeded 36 months [platinum-free interval: < 12 months, 3/48 (6%); 12–23 months, 0/19 (0%); 24–35 months, 2/19 (11%); ≥ 36 months, 3/20 (15%)].
Conclusions Re-administration of platinum-based chemotherapy for recurrent endometrial cancer may result in a long-term response exceeding the platinum-free interval in some patients. Even in the current situation, where immune checkpoint inhibitors have been introduced, re-administration of platinum-based chemotherapy is worth considering. en-copyright= kn-copyright=

Clipping and Balloon Angioplasty for Right Ventricular-Pulmonary Artery Shunt in Hypoplastic Left Heart Syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Controlling pulmonary blood flow in patients who have undergone Norwood palliation, especially early postoperatively, is challenging due to a change in the balance of systemic and pulmonary vascular resistance. We applied a combination therapy of clipping and balloon angioplasty for right ventricle—pulmonary artery (RV-PA) shunt to control pulmonary blood flow, but the influence of the combination therapy on the PA condition is uncertain. Retrospectively analysis was conducted of all infants with hypoplastic left heart syndrome who had undergone Norwood palliation with RV-PA shunt at Okayama University Hospital from January 2008 to September 2022. A total of 50 consecutive patients underwent Norwood palliation with RV-PA shunt in this study period. Of them, 29 patients underwent RV-PA shunt flow clipping, and the remaining 21 had unclipped RV-PA shunt. Twenty-three patients underwent balloon angioplasty for RV-PA shunt with clips. After balloon angioplasty, oxygen saturation significantly increased from 69 (59–76)% to 80 (72–86)% (p < 0.001), and the narrowest portion of the clipped conduit significantly improved from 2.8 (1.8–3.4) to 3.8 (2.9–4.6) mm (p < 0.001). In cardiac catheterizations prior to Bidirectional cavo-pulmonary shunt (BCPS), there were no significant differences in pulmonary-to-systemic flow ratio (Qp/Qs), ventricular end-diastolic pressure, Nakata index, arterial saturation, mean pulmonary artery pressure and pulmonary vascular resistance index. On the other hand, in Cardiac catheterizations prior to Fontan, Nakata index was larger in the clipped group (p = 0.02). There was no statistically significant difference in the 5-year survival between the two groups (clipped group 96%, unclipped group 74%, log-rank test: p = 0.13). At least, our combination therapy of clipping and balloon angioplasty for RV-PA shunt did not negatively impact PA growth. Although there is a trend toward better but not statistically significant difference in outcomes in the clipped group compared to the non-clipped group, this treatment strategy may play an important role in improving outcomes in hypoplastic left heart syndrome. en-copyright= kn-copyright= en-aut-name=ShigemitsuYusuke en-aut-sei=Shigemitsu en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KondoMaiko en-aut-sei=Kondo en-aut-mei=Maiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KuritaYoshihiko en-aut-sei=Kurita en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukushimaYosuke en-aut-sei=Fukushima en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawamotoYuya en-aut-sei=Kawamoto en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HiraiKenta en-aut-sei=Hirai en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HaraMayuko en-aut-sei=Hara en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KanazawaTomoyuki en-aut-sei=Kanazawa en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IwasakiTatsuo en-aut-sei=Iwasaki en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KasaharaShingo en-aut-sei=Kasahara en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KataokaKoichi en-aut-sei=Kataoka en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= en-aut-name=BabaKenji en-aut-sei=Baba en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Pediatric Anesthesiology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Pediatric Anesthesiology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Pediatric Anesthesiology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Cardiovascular Surgery, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= en-keyword=Hypoplastic left heart syndrome kn-keyword=Hypoplastic left heart syndrome en-keyword=Norwood palliation kn-keyword=Norwood palliation en-keyword=Balloon angioplasty kn-keyword=Balloon angioplasty en-keyword=Congenital heart disease kn-keyword=Congenital heart disease END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=15 article-no= start-page=2400078 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240704 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Unabsorbed Fecal Fat Content Correlates with a Reduction of Immunoglobulin a Coating of Gut Bacteria in High‐Lard Diet‐Fed Mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Scope: Immunoglobulin A (IgA) selectively coats gut bacteria and contributes to regulatory functions in gastrointestinal inflammation and glucose metabolism. Excess intake of lard leads to decrease in the IgA coating of gut bacteria, although the underlying mechanisms remain unknown. This study validates how unabsorbed fat derived from a high-lard diet in the gut affects the IgA coating of bacteria, as assessed in mouse models using three types of dietary fat (lard, medium-, and long-chain triglycerides [MLCTs], and medium-chain triglycerides [MCTs]) exhibiting different digestibilities.
Methods and results: C57BL/6J mice are maintained on diets containing lard, MLCTs, or MCTs at 7% or 30% w/w for 10 weeks (n = 6 per group). The fecal fatty acid concentration is measured to quantify unabsorbed fat content. The ratio of IgA-coated bacteria to total bacteria (IgA coating ratio) in the feces is measured by flow cytometry. Compared to lard-fed mice, MLCT- and MCT-fed mice exhibit lower fecal concentrations of palmitic acid, stearic acid, and oleic acid and higher IgA coating ratios at both 7% and 30% dietary fat, and these parameters exhibit significant negative correlations.
Conclusion: Unabsorbed fat content in the gut may result in attenuated IgA coating of bacteria in high-lard diet-fed mice.

Ca blockers and prostaglandins are used to treat peripheral circulatory disturbances. Chronic limb-threatening ischemia (CLTI) is a disease characterized by extremity ulcers, necrosis, and pain due to limb ischemia. Since only a few patients present with coexistence of CLTI and SSc, the treatment outcomes of revascularization in these cases are unknown. In this study, we evaluated the clinical characteristics and treatment outcomes of seven patients with CLTI and SSc, and 35 patients with uncomplicated CLTI who were hospitalized from 2012 to 2022. A higher proportion of patients with uncomplicated CLTI had diabetes and male. There were no significant differences in the age at which ischemic ulceration occurred, other comorbidities, or in treatments, including antimicrobial agents, revascularization and amputation, improvement of pain, and the survival time from ulcer onset between the two subgroups. EVT or amputation was performed in six or two of the seven patients with CLTI and SSc, respectively. Among those who underwent EVT, 33% (2/6) achieved epithelialization and 67% (4/6) experienced pain relief. These results suggest that the revascularization in cases with CLTI and SSc should consider factors such as infection and general condition, since revascularization improve the pain of these patients. en-copyright= kn-copyright= en-aut-name=MatsudaYoshihiro en-aut-sei=Matsuda en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyakeTomoko en-aut-sei=Miyake en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TodaHironobu en-aut-sei=Toda en-aut-mei=Hironobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TachibanaKota en-aut-sei=Tachibana en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NomuraHayato en-aut-sei=Nomura en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HiraiYoji en-aut-sei=Hirai en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawakamiYoshio en-aut-sei=Kawakami en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SakodaNaoya en-aut-sei=Sakoda en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MorizaneShin en-aut-sei=Morizane en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=chronic limb-threatening ischemia (CLTI) kn-keyword=chronic limb-threatening ischemia (CLTI) en-keyword=endovascular therapy (EVT) kn-keyword=endovascular therapy (EVT) en-keyword=revascularization kn-keyword=revascularization en-keyword=systemic sclerosis (SSc) kn-keyword=systemic sclerosis (SSc) END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=6 article-no= start-page=e11518 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240618 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Heterospecific interaction in two beetle species: Males with weapons decrease the reproductive success of species with weaponless males en-subtitle= kn-subtitle= en-abstract= kn-abstract=Many species often show male-male combat for mating opportunities and resources within the species. Sexual selection through this radical combat leads to the evolution of males with exaggerated traits used as weapons, such as horns or mandibles, that often result in victory during combat. However, heterospecific interaction due to errors in species identification has often been observed, which results in decreased mating opportunities within the same species and fewer fertilized eggs. Males with exaggerated weapons may show dominance in resource acquisition over males without weapons and may decrease the reproductive success of the latter due to competition between the two. However, few studies have examined heterospecific interaction focusing on males with or without weapons. In this study, we investigated the effects of the male weapon on reproductive traits in heterospecific interaction in two species: the broad-horned flour beetle (Gnatocerus cornutus), in which males have exaggerated weapon traits; and the red flour beetle (Tribolium castaneum), in which males have no weapon traits. Both species are closely related and use the same food resources. G. cornutus males interfered with the resource acquisition and reproductive opportunities of T. castaneum by attacking T. castaneum. The reproductive success of T. castaneum decreased when they cohabited with G. cornutus males. These findings show that male weapon traits, which are important for sexual selection within the same species, can also greatly influence reproduction in other species. en-copyright= kn-copyright= en-aut-name=OnishiRui en-aut-sei=Onishi en-aut-mei=Rui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumuraKentarou en-aut-sei=Matsumura en-aut-mei=Kentarou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Natural Science, and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Natural Science, and Technology, Okayama University kn-affil= en-keyword=Gnatocerus cornutus kn-keyword=Gnatocerus cornutus en-keyword=heterospecific interaction kn-keyword=heterospecific interaction en-keyword=male-male competition kn-keyword=male-male competition en-keyword=sexual selection kn-keyword=sexual selection en-keyword=Tribolium castaneum kn-keyword=Tribolium castaneum END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=3 article-no= start-page=276 end-page=281 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202405 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Postnatal longitudinal analysis of serum nitric oxide and eosinophil counts in extremely preterm infants en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Nitric oxide (NO) may be related to the pathogenesis of several morbidities in extremely preterm infants, including late-onset adrenal insufficiency. However, eosinophilia is observed under pathological conditions with adrenal insufficiency. Therefore, this study explored postnatal changes in NO levels and eosinophil counts in extremely preterm infants with and without morbidities.
Methods: Nineteen extremely preterm infants with a median gestational age of 27.0 weeks and median birth weight of 888 g were enrolled in this study. Serum levels of nitrogen oxides (NOx) and peripheral blood eosinophil counts were measured at birth and every 2 weeks thereafter. Morbidities of the study group were diagnosed using a single criterion.
Results: Serum NOx levels (mean ± standard deviation) were 22.5 ± 14.9 μmol/L, 51.2 ± 23.7 μmol/L, 42.4 ± 15.2 μmol/L, and 33.8 ± 9.4 μmol/L at birth and 2, 4, and 6 weeks of age, respectively. The serum NOx level at 2 weeks of age was significantly higher than that at birth and 6 weeks of age. Eosinophil counts, which increase with adrenal insufficiency, were measured simultaneously and were 145 ± 199/μL, 613 ± 625/μL, 466 ± 375/μL, and 292 ± 228/μL at birth and 2, 4, and 6 weeks of age, respectively. These values showed that the eosinophil count was significantly higher at 2 weeks of age than at birth and 6 weeks of age. The serum NOx level of infants without chorioamnionitis was significantly increased at 4 weeks of age, and the eosinophil count of infants with necrotizing enterocolitis was significantly increased at 2 weeks of age. No correlation with the NOx level or eosinophil count was observed in infants with late-onset circulatory collapse.
Conclusion: The postnatal serum NOx level and eosinophil count were significantly correlated with each other and peaked at 2 weeks of age. en-copyright= kn-copyright= en-aut-name=WatanabeHirokazu en-aut-sei=Watanabe en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WashioYosuke en-aut-sei=Washio en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TamaiKei en-aut-sei=Tamai en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MorimotoDaisaku en-aut-sei=Morimoto en-aut-mei=Daisaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkamuraTomoka en-aut-sei=Okamura en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshimotoJunko en-aut-sei=Yoshimoto en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakanishiHidehiko en-aut-sei=Nakanishi en-aut-mei=Hidehiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KageyamaMisao en-aut-sei=Kageyama en-aut-mei=Misao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UchiyamaAtsushi en-aut-sei=Uchiyama en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KusudaSatoshi en-aut-sei=Kusuda en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Pediatrics, Graduate School of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Pediatrics, Graduate School of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Neonatology, Okayama Medical Center, National Hospital Organization kn-affil= affil-num=4 en-affil=Department of Pediatrics, Graduate School of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Pediatrics, Graduate School of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil= affil-num=6 en-affil=Department of Pediatrics, Graduate School of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil= affil-num=7 en-affil=Department of Neonatology, Maternal and Perinatal Center, Tokyo Women’s Medical University kn-affil= affil-num=8 en-affil=Department of Neonatology, Okayama Medical Center, National Hospital Organization kn-affil= affil-num=9 en-affil=Department of Neonatology, Maternal and Perinatal Center, Tokyo Women’s Medical University kn-affil= affil-num=10 en-affil=Department of Pediatrics, Graduate School of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil= affil-num=11 en-affil=Department of Neonatology, Maternal and Perinatal Center, Tokyo Women’s Medical University kn-affil= en-keyword=eosinophils kn-keyword=eosinophils en-keyword=extremely preterm infant kn-keyword=extremely preterm infant en-keyword=nitric oxide kn-keyword=nitric oxide en-keyword=relative adrenal insufficiency kn-keyword=relative adrenal insufficiency END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=3 article-no= start-page=291 end-page=294 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202406 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Case of Gallbladder Metastasis of Malignant Melanoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the clinical course of malignant melanoma, which can metastasize to multiple organs, gallbladder metastases are rarely detected. A 69-year-old man who underwent resection of a primary malignant melanoma was subsequently treated with nivolumab for lung metastases and achieved complete response. Seven years after surgery, multiple nodules were found in the gallbladder, and he underwent laparoscopic cholecystectomy. The postoperative diagnosis was metastases of malignant melanoma. He has been recurrence-free 8 months after surgery. If radical resection is possible, such surgery should be performed for gallbladder metastases found in patients with other controlled lesions of malignant melanoma. en-copyright= kn-copyright= en-aut-name=MinagiHitoshi en-aut-sei=Minagi en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AokiHideki en-aut-sei=Aoki en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DoitaSusumu en-aut-sei=Doita en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyakeEiki en-aut-sei=Miyake en-aut-mei=Eiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OgawaToshihiro en-aut-sei=Ogawa en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TaniguchiFumitaka en-aut-sei=Taniguchi en-aut-mei=Fumitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=ArataTakashi en-aut-sei=Arata en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KatsudaKoh en-aut-sei=Katsuda en-aut-mei=Koh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakayaKohji en-aut-sei=Tanakaya en-aut-mei=Kohji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Surgery, National Hospital Organization, Iwakuni Clinical Center kn-affil= affil-num=2 en-affil=Department of Surgery, National Hospital Organization, Iwakuni Clinical Center kn-affil= affil-num=3 en-affil=Department of Surgery, National Hospital Organization, Iwakuni Clinical Center kn-affil= affil-num=4 en-affil=Department of Surgery, National Hospital Organization, Iwakuni Clinical Center kn-affil= affil-num=5 en-affil=Department of Surgery, National Hospital Organization, Iwakuni Clinical Center kn-affil= affil-num=6 en-affil=Department of Surgery, National Hospital Organization, Iwakuni Clinical Center kn-affil= affil-num=7 en-affil=Department of Surgery, National Hospital Organization, Iwakuni Clinical Center kn-affil= affil-num=8 en-affil=Department of Surgery, National Hospital Organization, Iwakuni Clinical Center kn-affil= affil-num=9 en-affil=Department of Surgery, National Hospital Organization, Iwakuni Clinical Center kn-affil= affil-num=10 en-affil=Department of Surgery, National Hospital Organization, Iwakuni Clinical Center kn-affil= en-keyword=malignant melanoma kn-keyword=malignant melanoma en-keyword=gallbladder metastasis kn-keyword=gallbladder metastasis en-keyword=laparoscopic cholecystectomy kn-keyword=laparoscopic cholecystectomy END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=3 article-no= start-page=245 end-page=250 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202406 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Impact of Reduced Skeletal Muscle Mass on Patients with Knee Osteoarthritis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although several studies have suggested a possible association between sarcopenia and knee osteoarthritis (OA) in the elderly, there remains no definitive evidence. Recently, however, the serum creatinine/cystatin C ratio (sarcopenia index: SI) was reported to correlate with skeletal muscle mass. The present retrospective study therefore investigated the impact of reduced skeletal muscle mass on advanced knee OA using SI. In 55 individuals scheduled for knee osteotomy or knee arthroplasty, correlations between SI and patient-reported outcomes such as the Knee Society Score (KSS), Knee Injury and Osteoarthritis Outcome Score (KOOS), and Oxford Knee Score (OKS) were explored. Significant associations were found between SI and the KSS functional activity score (β=0.37; p=0.022), KOOS subscale for activities of daily living (β=0.42; p=0.0096), and OKS (β=0.42; p=0.0095). This study underscores the role of reduced muscle mass in functional outcomes and introduces SI as a valuable marker for assessing muscle loss in knee OA patients. en-copyright= kn-copyright= en-aut-name=AkagawaManabu en-aut-sei=Akagawa en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoHidetomo en-aut-sei=Saito en-aut-mei=Hidetomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakahashiYasuhiro en-aut-sei=Takahashi en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IwamotoYosuke en-aut-sei=Iwamoto en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IidaJunpei en-aut-sei=Iida en-aut-mei=Junpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshikawaTakayuki en-aut-sei=Yoshikawa en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AbeToshiki en-aut-sei=Abe en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SaitoKimio en-aut-sei=Saito en-aut-mei=Kimio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KijimaHiroaki en-aut-sei=Kijima en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KasukawaYuji en-aut-sei=Kasukawa en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HongoMichio en-aut-sei=Hongo en-aut-mei=Michio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MiyakoshiNaohisa en-aut-sei=Miyakoshi en-aut-mei=Naohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Omagari Kousei Medical Center kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Omagari Kousei Medical Center kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Omagari Kousei Medical Center kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Omagari Kousei Medical Center kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Omagari Kousei Medical Center kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Omagari Kousei Medical Center kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=12 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= en-keyword=knee osteoarthritis kn-keyword=knee osteoarthritis en-keyword=sarcopenia index kn-keyword=sarcopenia index en-keyword=reduced muscle mass kn-keyword=reduced muscle mass en-keyword=activities of daily living kn-keyword=activities of daily living en-keyword=functional activity kn-keyword=functional activity END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=3 article-no= start-page=215 end-page=225 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202406 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Assessment of a New Elbow Joint Positioning Method Using Area Detector Computed Tomography en-subtitle= kn-subtitle= en-abstract= kn-abstract=We propose a sitting position that achieves both high image quality and a reduced radiation dose in elbow joint imaging by area detector computed tomography (ADCT), and we compared it with the ‘superman’ and supine positions. The volumetric CT dose index (CTDIvol) for the sitting, superman, and supine positions were 2.7, 8.0, and 20.0 mGy and the dose length products (DLPs) were 43.4, 204.7, and 584.8 mGy • cm, respectively. In the task-based transfer function (TTF), the highest value was obtained for the sitting position in both bone and soft tissue images. The noise power spectrum (NPS) of bone images showed that the superman position had the lowest value up to approx. 1.1 cycles/mm or lower, whereas the sitting position had the lowest value when the NPS was greater than approx. 1.1 cycles/mm. The overall image quality in an observer study resulted in the following median Likert scores for Readers 1 and 2: 5.0 and 5.0 for the sitting position, 4.0 and 3.5 for the superman position, and 4.0 and 2.0 for the supine position. These results indicate that our proposed sitting position with ADCT of the elbow joint can provide superior image quality and allow lower radiation doses compared to the superman and supine positions. en-copyright= kn-copyright= en-aut-name=AkagawaTakuya en-aut-sei=Akagawa en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukuiRyohei en-aut-sei=Fukui en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KidaKatsuhiro en-aut-sei=Kida en-aut-mei=Katsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsuuraRyutaro en-aut-sei=Matsuura en-aut-mei=Ryutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShimadaMakoto en-aut-sei=Shimada en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KinoshitaMitsuhiro en-aut-sei=Kinoshita en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AkagawaYoko en-aut-sei=Akagawa en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=GotoSachiko en-aut-sei=Goto en-aut-mei=Sachiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Radiological Technology, Tokushima Red Cross Hospital kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Radiology, Osaka International Cancer Institute kn-affil= affil-num=6 en-affil=Department of Radiology, Tokushima Red Cross Hospital kn-affil= affil-num=7 en-affil=Department of Radiology, Tokushima Red Cross Hospital kn-affil= affil-num=8 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= en-keyword=area detector computed tomography kn-keyword=area detector computed tomography en-keyword=elbow joint kn-keyword=elbow joint en-keyword=sitting position kn-keyword=sitting position en-keyword=dose reduction kn-keyword=dose reduction en-keyword=image quality assessment kn-keyword=image quality assessment END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=5 article-no= start-page=877 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240427 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Isolation of Vibrio cholerae and Vibrio vulnificus from Estuarine Waters, and Genotyping of V. vulnificus Isolates Using Loop-Mediated Isothermal Amplification en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bacteria in the genus Vibrio are ubiquitous in estuarine and coastal waters. Some species (including Vibrio cholerae and Vibrio vulnificus) are known human pathogens causing ailments like cholera, diarrhea, or septicemia. Notably, V. vulnificus can also cause a severe systemic infection (known as vibriosis) in eels raised in aquaculture facilities. Water samples were periodically collected from the estuary of the Asahi River, located in the southern part of Okayama City, Japan. These samples were directly plated onto CHROMagar Vibrio plates, and colonies displaying turquoise-blue coloration were selected. Thereafter, polymerase chain reaction was used to identify V. cholerae and V. vulnificus. A total of 30 V. cholerae strains and 194 V. vulnificus strains were isolated during the warm season when the water temperature (WT) was higher than 20 degrees C. Concurrently, an increase in coliforms was observed during this period. Notably, V. vulnificus has two genotypes, designated as genotype 1 and genotype 2. Genotype 1 is pathogenic to humans, while genotype 2 is pathogenic to both humans and eels. The loop-mediated isothermal amplification method was developed to rapidly determine genotypes at a low cost. Of the 194 strains isolated, 80 (41.2%) were identified as genotype 1 strains. Among the 41 strains isolated when the WTs were higher than 28 degrees C, 25 strains (61.0%) belonged to genotype 1. In contrast, of the 32 strains isolated when the WTs were lower than 24 degrees C, 27 strains (84.4%) belonged to genotype 2. These results suggest that the distribution of the two genotypes was influenced by WT. en-copyright= kn-copyright= en-aut-name=MiyoshiShin-Ichi en-aut-sei=Miyoshi en-aut-mei=Shin-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KurataMegumi en-aut-sei=Kurata en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiroseRiho en-aut-sei=Hirose en-aut-mei=Riho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshikawaMasaya en-aut-sei=Yoshikawa en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=LiangYong en-aut-sei=Liang en-aut-mei=Yong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamagishiYosuke en-aut-sei=Yamagishi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MizunoTamaki en-aut-sei=Mizuno en-aut-mei=Tamaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Vibrio cholerae kn-keyword=Vibrio cholerae en-keyword=Vibrio vulnificus kn-keyword=Vibrio vulnificus en-keyword=genotype kn-keyword=genotype en-keyword=LAMP kn-keyword=LAMP en-keyword=water temperature kn-keyword=water temperature END start-ver=1.4 cd-journal=joma no-vol=165 cd-vols= no-issue= article-no= start-page=106013 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202409 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Salivary buffering capacity is correlated with umami but not sour taste sensitivity in healthy adult Japanese subjects en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: Saliva serves multiple important functions crucial for maintaining a healthy oral and systemic environment. Among them, the pH buffering effect, which is primarily mediated by bicarbonate ions, helps maintain oral homeostasis by neutralizing acidity from ingested foods. Therefore, higher buffering capacity, reflecting the ability to neutralize oral acidity, may influence taste sensitivity, especially for sour taste since it involves sensing H+ ions. This study aims to explore the relationship between salivary buffering capacity and taste sensitivities to the five basic tastes in healthy adult humans.
Design: Eighty seven healthy adult students participated in this study. Resting saliva volume was measured using the spitting method. The liquid colorimetric test was used to assess salivary buffering capacity. The whole-mouth taste testing method was employed to determine the recognition threshold for each tastant (NaCl, sucrose, citric acid, quinine-HCl, monosodium glutamate).
Results: Taste recognition thresholds for sour taste as well as sweet, salty, and bitter tastes showed no correlation with salivary buffering capacity. Interestingly, a negative relationship was observed between recognition threshold for umami taste and salivary buffering capacity. Furthermore, a positive correlation between salivary buffering capacity and resting saliva volume was observed.
Conclusions: Salivary buffering capacity primarily influences sensitivity to umami taste, but not sour and other tastes. en-copyright= kn-copyright= en-aut-name=HyodoAiko en-aut-sei=Hyodo

en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sweet and umami taste receptors recognize chemicals such as sugars and amino acids on their extracellular side and transmit signals into the cytosol of the taste cell. In contrast to ligands that act on the extracellular side of these receptors, little is known regarding the molecules that regulate receptor functions within the cytosol. In this study, we analysed the interaction between sweet and umami taste receptors and calmodulin, a representative Ca2+-dependent cytosolic regulatory protein. High prediction scores for calmodulin binding were observed on the C-terminal cytosolic side of mouse taste receptor type 1 subunit 3 (T1r3), a subunit that is common to both sweet and umami taste receptors. Pull-down assay and surface plasmon resonance analyses showed different affinities of calmodulin to the C-terminal tails of distinct T1r subtypes. Furthermore, we found that T1r3 and T1r2 showed the highest and considerable binding to calmodulin, whereas T1r1 showed weaker binding affinity. Finally, the binding of calmodulin to T1rs was consistently higher in the presence of Ca2+ than in its absence. The results suggested a possibility of the Ca2+-dependent feedback regulation process of sweet and umami taste receptor signaling by calmodulin. en-copyright= kn-copyright= en-aut-name=YoshidaAtsuki en-aut-sei=Yoshida en-aut-mei=Atsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ItoAyumi en-aut-sei=Ito en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=YamashitaAtsuko en-aut-sei=Yamashita en-aut-mei=Atsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=calmodulin kn-keyword=calmodulin en-keyword=cytosol kn-keyword=cytosol en-keyword=sweet taste kn-keyword=sweet taste en-keyword=taste receptor type 1 kn-keyword=taste receptor type 1 en-keyword=umami taste kn-keyword=umami taste END start-ver=1.4 cd-journal=joma no-vol=120 cd-vols= no-issue=1 article-no= start-page=128 end-page=134 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240415 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Spontaneous regression of multiple solitary plasmacytoma harboring Epstein–Barr virus: a case report and literature review en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a rare case of spontaneous regression (SR) in an elderly untreated patient with multiple solitary plasmacytoma (MSP). Diagnosis of MSP was confirmed through surgical resection of the left nasal cavity mass and subsequent biopsy of the right humerus. The patient was considered ineligible for chemotherapy due to poor performance status. At 3-month post-diagnosis, the patient’s condition worsened with deteriorating bone lesions and emergence of a new serum monoclonal protein. However, these clinical findings completely disappeared at 6 months, and positron emission tomography–computed tomography at 1 year confirmed complete metabolic remission. Notably, peripheral blood lymphocyte counts were inversely correlated with tumor progression and remission. Pathological re-evaluation of the initial biopsy specimens revealed programmed cell death protein 1 (PD-1) expression in tumor-infiltrating CD8+ T cells. In addition, tumor cells were infected with Epstein–Barr virus (EBV) but were negative for programmed cell death ligand 1 (PD-L1) expression, which is the most potent immune escape mechanism in tumor cells. While the mechanism underlying SR remains unclear, our findings suggest that host immune response as well as EBV infection may contribute to SR. Further studies are needed to elucidate the clinicopathologic mechanisms of tumor regression in plasma cell neoplasms. en-copyright= kn-copyright= en-aut-name=KitamuraWataru en-aut-sei=Kitamura en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobayashiHiroki en-aut-sei=Kobayashi en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NodaMinori en-aut-sei=Noda en-aut-mei=Minori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IsekiAkiko en-aut-sei=Iseki en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SatoYumi en-aut-sei=Sato en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=KuyamaShoichi en-aut-sei=Kuyama en-aut-mei=Shoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Otorhinolaryngology, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=4 en-affil=Department of Pathology, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=5 en-affil=Department of Pathology, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=6 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Respiratory Medicine, National Hospital Organization Iwakuni Clinical Center kn-affil= en-keyword=Plasmacytoma kn-keyword=Plasmacytoma en-keyword=Epstein–Barr virus kn-keyword=Epstein–Barr virus en-keyword=Spontaneous regression kn-keyword=Spontaneous regression END start-ver=1.4 cd-journal=joma no-vol=52 cd-vols= no-issue=10 article-no= start-page=5825 end-page=5840 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240425 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The ABCF proteins in Escherichia coli individually cope with 'hard-to-translate' nascent peptide sequences en-subtitle= kn-subtitle= en-abstract= kn-abstract=Organisms possess a wide variety of proteins with diverse amino acid sequences, and their synthesis relies on the ribosome. 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=38 cd-vols= no-issue=9 article-no= start-page=1181 end-page=1189 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230423 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prognostic value of the liver fibrosis marker fibrosis-5 index in patients with severe isolated tricuspid regurgitation: comparison with fibrosis-4 index en-subtitle= kn-subtitle= en-abstract= kn-abstract=The fibrosis-4 index (FIB4), a liver fibrosis maker, has been shown to be associated with the prognosis in patients with severe isolated tricuspid regurgitation (TR). Recent study showed that the fibrosis-5 index (FIB5), which was calculated by albumin, alkaline phosphatase, aspartate transaminase, alanine aminotransferase and platelet count, had better prognostic value than FIB4 in patients with heart failure. The aim of this study was to evaluate the usefulness of FIB5 index for predicting prognosis in patients with severe isolated TR and compare the prognostic value between the FIB4 and the FIB5 in those patients. This was a dual-center, retrospective study. 113 consecutive outpatients with severe isolated TR (mean age, 65.8 years; 47.8% male) were analyzed. Major adverse cardiovascular events (MACEs) were defined as the composite of cardiovascular death, hospitalization for heart failure, myocardial infarction, and stroke. During a median follow-up of 3.0 years, 41 MACEs occurred. Patients with MACEs had a lower the FIB5 than patients without MACEs. The multivariate Cox analysis revealed that the FIB5 < -4.30 was significantly associated with higher incidence of MACEs after adjusted by confounding factors. Receiver-operating characteristic curve analyses showed that prognostic values did not differ between the FIB5 and the FIB4 in whole patients and in patients aged ≥ 70 years; while, in patients aged < 70 years, the FIB5 had better prognostic value than the FIB4. The FIB5 may be a useful predictor of MACEs in patients with severe isolated TR. en-copyright= kn-copyright= en-aut-name=NakashimaMitsutaka en-aut-sei=Nakashima en-aut-mei=Mitsutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=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=TanakayaMachiko en-aut-sei=Tanakaya en-aut-mei=Machiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoTakaaki en-aut-sei=Saito en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatayamaYusuke en-aut-sei=Katayama en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, National Hospital Organization Iwakuni Clinical Center 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= en-keyword=Liver disorder kn-keyword=Liver disorder en-keyword=Fibrosis-4 index kn-keyword=Fibrosis-4 index en-keyword=Fibrosis-5 index kn-keyword=Fibrosis-5 index en-keyword=Isolated tricuspid regurgitation kn-keyword=Isolated tricuspid regurgitation en-keyword=Major adverse cardiac events kn-keyword=Major adverse cardiac events END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=3 article-no= start-page=548 end-page=556 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230407 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Outcomes of solitary postoperative recurrence of esophageal squamous cell carcinoma diagnosed with FDG-PET/CT and treated with definitive radiation therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Surgical resection of esophageal cancer is frequently performed to achieve a complete cure. However, the postoperative recurrence rate is 36.8–42.5%, leading to poor prognosis. Radiation therapy has been used to treat recurrences; solitary recurrence has been proposed as a prognostic factor for radiation therapy, though its significance is unclear. 18F-fluorodeoxyglucose positron emission tomography is a highly accurate diagnostic modality for esophageal cancer. This retrospective study aimed to analyze the outcomes of solitary postoperative recurrences of esophageal squamous cell carcinoma diagnosed with 18F-fluorodeoxyglucose positron emission tomography and treated with definitive radiation therapy.
Methods We examined 27 patients who underwent definitive radiation therapy for single or multiple postoperative recurrences of esophageal squamous cell carcinoma between May 2015 and April 2021. 18F-fluorodeoxyglucose positron emission tomography/computed tomography was performed within 3 months before the commencement of radiation therapy. Kaplan–Meier, univariate, and multivariate analyses were performed to examine the overall survival and identify potential prognostic factors.
Results The 1-, 2-, and 3-year overall survival rates were 85.2%, 62.6%, and 47.3%, respectively, and solitary recurrence was the only significant factor associated with overall survival (P = 0.003). The 1-, 2-, and 3-year overall survival rates in patients with solitary recurrence were 91.7%, 80.2%, and 80.2%, respectively, and in patients with multiple recurrences they were 80.0%, 50.3%, and 25.1%, respectively. Multivariate analysis also showed solitary recurrence as a significant factor for overall survival.
Conclusions When diagnosed with 18F-fluorodeoxyglucose positron emission tomography/computed tomography, solitary recurrence appears to have a more favorable prognosis than multiple recurrences. en-copyright= kn-copyright= en-aut-name=IharaHiroki en-aut-sei=Ihara en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshioKotaro en-aut-sei=Yoshio en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=SugiyamaSoichi en-aut-sei=Sugiyama en-aut-mei=Soichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HashimotoMasashi en-aut-sei=Hashimoto en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MaedaNaoaki en-aut-sei=Maeda en-aut-mei=Naoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AkagiShinsuke en-aut-sei=Akagi en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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=10 ORCID= affil-num=1 en-affil=Department of Radiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Proton Beam Therapy, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Proton Beam Therapy, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Radiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Radiation therapy kn-keyword=Radiation therapy en-keyword=Esophageal squamous cell carcinoma kn-keyword=Esophageal squamous cell carcinoma en-keyword=Recurrence kn-keyword=Recurrence en-keyword=18F-fluorodeoxyglucose positron emission tomography kn-keyword=18F-fluorodeoxyglucose positron emission tomography en-keyword=Survival kn-keyword=Survival END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=201 end-page=204 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Case of Gallbladder Cancer with Trousseau Syndrome Successfully Treated Using Radical Resection en-subtitle= kn-subtitle= en-abstract= kn-abstract=Trousseau syndrome is characterized by cancer-associated systemic thrombosis. We describe the first case of a successfully treated gallbladder adenocarcinoma accompanied by Trousseau syndrome. A 66-year-old woman presented with right hemiplegia. Magnetic resonance imaging identified multiple cerebral infarctions. Her serum carbohydrate antigen 19-9 and D-dimer levels were markedly elevated, and a gallbladder tumor was detected via abdominal computed tomography. Venous ultrasonography of the lower limbs revealed a deep venous thrombus in the right peroneal vein. These findings suggested that the brain infarctions were likely caused by Trousseau syndrome associated with her gallbladder cancer. Radical resection of the gallbladder tumor was performed. The resected gallbladder was filled with mucus and was pathologically diagnosed as an adenocarcinoma. Her postoperative course was uneventful, and she received a one-year course of adjuvant therapy with oral S-1. No cancer recurrence or thrombosis was noted 26 months postoperatively. Despite concurrent Trousseau syndrome, a radical cure of the primary tumor and thrombosis could be achieved with the appropriate treatment. en-copyright= kn-copyright= en-aut-name=MasunagaAkari en-aut-sei=Masunaga en-aut-mei=Akari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=YoshimatsuRika en-aut-sei=Yoshimatsu en-aut-mei=Rika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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=7 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 Radiology, Kochi Health Sciences Center kn-affil= affil-num=5 en-affil=Department of Radiology, 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 Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= en-keyword=gallbladder cancer kn-keyword=gallbladder cancer en-keyword=Trousseau syndrome kn-keyword=Trousseau syndrome en-keyword=radical surgery kn-keyword=radical surgery END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=163 end-page=170 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Impact of Light Touch and Pin Prick on Functional Outcomes in Patients with Traumatic Spinal Cord Injury en-subtitle= kn-subtitle= en-abstract= kn-abstract=A spinal cord injury (SCI) can cause severe lifelong functional disability and profoundly affect an individual’s daily life. We investigated the prediction of patients’ post-SCI functional outcomes by evaluating sensory scores rather than motor scores, as the latter’s association with functional outcomes is well established. We examined patients’ responses to a light touch (LT) and pin prick (PP) at admission and the response data’s usefulness as predictors of functional outcomes (i.e., ability to perform activities of daily living) at discharge. This exploratory observational study used data from the Japanese National Spinal Cord Injury Database (SCI-J). Data from 3,676 patients who met the inclusion criteria and were admitted for an SCI between 1997 and 2020 were analyzed. The motor score of the Functional Independence Measure (mFIM) at discharge was used as an index of functional outcome. A multiple regression analysis revealed that the mFIM was associated with both the LT response (β=0.07 (0.01), p<0.001) and the PP response (β=0.07 (0.01), p<0.001) at admission. The false discovery rate log-worth values for LT and PP were 6.6 and 8.5, respectively. Our findings demonstrate that LT and PP scores at admission can help predict patients’ functional outcomes after an SCI, although the magnitude of their contributions is not high. en-copyright= kn-copyright= en-aut-name=DeguchiTakayuki en-aut-sei=Deguchi en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KandaKanae en-aut-sei=Kanda en-aut-mei=Kanae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FurusawaKazunari en-aut-sei=Furusawa en-aut-mei=Kazunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Nlandu Roger Ngatu en-aut-sei=Nlandu Roger Ngatu en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiraoTomohiro en-aut-sei=Hirao en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Rehabilitation, Kagawa Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= affil-num=3 en-affil=Department of Rehabilitation Medicine, Kibikogen Rehabilitation Center for Employment Injuries kn-affil= affil-num=4 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= affil-num=5 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= en-keyword=functional independence measure kn-keyword=functional independence measure en-keyword=light touch kn-keyword=light touch en-keyword=pin prick kn-keyword=pin prick en-keyword=spinal cord injury kn-keyword=spinal cord injury en-keyword=Japanese National Spinal Cord Injury Database kn-keyword=Japanese National Spinal Cord Injury Database END start-ver=1.4 cd-journal=joma no-vol=160 cd-vols= no-issue=9 article-no= start-page=094101 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240301 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=GenIce-core: Efficient algorithm for generation of hydrogen-disordered ice structures en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ice is different from ordinary crystals because it contains randomness, which means that statistical treatment based on ensemble averaging is essential. Ice structures are constrained by topological rules known as the ice rules, which give them unique anomalous properties. These properties become more apparent when the system size is large. For this reason, there is a need to produce a large number of sufficiently large crystals that are homogeneously random and satisfy the ice rules. We have developed an algorithm to quickly generate ice structures containing ions and defects. This algorithm is provided as an independent software module that can be incorporated into crystal structure generation software. By doing so, it becomes possible to simulate ice crystals on a previously impossible scale. en-copyright= kn-copyright= en-aut-name=MatsumotoMasakazu en-aut-sei=Matsumoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YagasakiTakuma en-aut-sei=Yagasaki en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaHideki en-aut-sei=Tanaka en-aut-mei=Hideki 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=Division of Chemical Engineering, Graduate School of Engineering Science, Osaka University kn-affil= affil-num=3 en-affil=Toyota Physical and Chemical Research Institute kn-affil= END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=2 article-no= start-page=e0297347 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Japan-epiretinal membrane (J-ERM) registry: A prospective cohort study protocol investigating the surgical outcome of epiretinal membrane en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Epiretinal membrane (ERM) causes visual impairment such as reduction in visual acuity and metamorphopsia due to retinal traction. With the improvement of optical coherence tomography (OCT) and microincision vitrectomy surgery (MIVS), the surgery of ERM has significantly advanced. However, there have been no large-scale studies on the following: (1) how to evaluate visual impairment in ERM, (2) the relationship between OCT findings and visual function, (3) when is the optimal timing of surgery, and (4) the relationship between the surgical instruments as well as techniques and prognosis. The purpose of this study was to obtain evidence regarding these ERM surgeries.
Methods and design
This is a prospective, multicenter cohort study of ERM surgery in Japan from March 1, 2023, to March 31, 2027 (UMIN000048472, R-3468-2). Patients who underwent ERM surgery during the study period and agreed to participate in this study will be included. The goal is to have a total of 5,000 eyes surgically treated for ERM. The following data will be collected: age, gender, medical history, subjective symptoms, visual function before and 6 and 12 months after surgery, clinical findings, OCT data, surgical technique, instruments used in surgery, and complications.
Discussion
The results of this study will support the surgical decisions and procedures in ERM practices. en-copyright= kn-copyright= en-aut-name=KanzakiYuki en-aut-sei=Kanzaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatobaRyo en-aut-sei=Matoba en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshiharaKenji en-aut-sei=Ishihara en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoritaTetsuro en-aut-sei=Morita en-aut-mei=Tetsuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MuraokaYuki en-aut-sei=Muraoka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KimuraShuhei en-aut-sei=Kimura en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KotoTakashi en-aut-sei=Koto en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawasakiRyo en-aut-sei=Kawasaki en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=BabaTakayuki en-aut-sei=Baba en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkamotoFumiki en-aut-sei=Okamoto en-aut-mei=Fumiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=InoueMakoto en-aut-sei=Inoue en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=SakamotoTaiji en-aut-sei=Sakamoto en-aut-mei=Taiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TsujikawaAkitaka en-aut-sei=Tsujikawa en-aut-mei=Akitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MorizaneYuki en-aut-sei=Morizane en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Ophthalmology and Visual Sciences, Kyoto University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Ophthalmology and Visual Sciences, Kyoto University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Kyorin Eye Center, Department of Ophthalmology, Kyorin University School of Medicine kn-affil= affil-num=8 en-affil=Division of Public Health, Department of Social Medicine, Osaka University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Ophthalmology and Visual Science, Chiba University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Department of Ophthalmology, Graduate School of Medicine, Nippon Medical School kn-affil= affil-num=11 en-affil=Kyorin Eye Center, Department of Ophthalmology, Kyorin University School of Medicine kn-affil= affil-num=12 en-affil=Department of Ophthalmology, Kagoshima University Graduate School of Medical and Dental Sciences kn-affil= affil-num=13 en-affil=Department of Ophthalmology and Visual Sciences, Kyoto University Graduate School of Medicine kn-affil= affil-num=14 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=626 cd-vols= no-issue=7999 article-no= start-page=670 end-page=677 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240131 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Oxygen-evolving photosystem II structures during S1–S2–S3 transitions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photosystem II (PSII) catalyses the oxidation of water through a four-step cycle of Si states (i = 0–4) at the Mn4CaO5 cluster1,2,3, during which an extra oxygen (O6) is incorporated at the S3 state to form a possible dioxygen4,5,6,7. Structural changes of the metal cluster and its environment during the S-state transitions have been studied on the microsecond timescale. Here we use pump-probe serial femtosecond crystallography to reveal the structural dynamics of PSII from nanoseconds to milliseconds after illumination with one flash (1F) or two flashes (2F). YZ, a tyrosine residue that connects the reaction centre P680 and the Mn4CaO5 cluster, showed structural changes on a nanosecond timescale, as did its surrounding amino acid residues and water molecules, reflecting the fast transfer of electrons and protons after flash illumination. Notably, one water molecule emerged in the vicinity of Glu189 of the D1 subunit of PSII (D1-E189), and was bound to the Ca2+ ion on a sub-microsecond timescale after 2F illumination. This water molecule disappeared later with the concomitant increase of O6, suggesting that it is the origin of O6. We also observed concerted movements of water molecules in the O1, O4 and Cl-1 channels and their surrounding amino acid residues to complete the sequence of electron transfer, proton release and substrate water delivery. These results provide crucial insights into the structural dynamics of PSII during S-state transitions as well as O–O bond formation. en-copyright= kn-copyright= en-aut-name=LiHongjie en-aut-sei=Li

among older adults attending a university hospital dental clinic: A cross-sectional study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Positive psychological well-being has a favorable impact on survival rates in both healthy and unhealthy populations. Oral health is also associated with psychological well-being, is multidimensional in nature, and includes physical, psychological, emotional, and social domains that are integral to overall health and well-being. This study aimed to identify the associations between individual and environmental characteristics, oral condition and nutritional status in relation to subjective well-being among older adults using the Wilson and Cleary conceptual model. The participants were older adults (age >= 60 years) attending a university hospital. Subjective well-being was assessed using the World Health Organization-5 Well-Being Index, oral condition was assessed based on the number of bacteria in the tongue coating, oral wettability, tongue pressure, occlusal force, oral diadochokinesis, and masticatory ability, and subjective swallowing function was assessed using the Eating Assessment Tool, number of remaining teeth, and number of functional teeth. In addition, factors related to well-being, including social networks, life-space mobility, nutritional status, smoking history, drinking history, and medical history were assessed. In the analysis, structural equation modeling was used to investigate the association between oral condition and subjective well-being. Confirmatory factor analysis revealed oral condition as a latent variable, including tongue pressure, oral diadochokinesis /pa/, /ta/, /ka/, occlusal force, masticatory ability, subjective swallowing function, and number of functional teeth. Structural Equation Modeling revealed that oral condition was positively correlated with nutritional status, and nutritional status was positively correlated with the World Health Organization-5 Well-Being Index. These findings suggest that oral condition may influence subjective well-being via nutritional status or social environmental factors. en-copyright= kn-copyright= en-aut-name=TakeuchiNoriko en-aut-sei=Takeuchi en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SawadaNanami en-aut-sei=Sawada en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Preventive Dentistry, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Preventive Dentistry, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Health, Takarazuka University of Medical and Health Care kn-affil= END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=3 article-no= start-page=1443 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240124 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Inhibitory Effect of a Tankyrase Inhibitor on Mechanical Stress-Induced Protease Expression in Human Articular Chondrocytes en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated the effects of a Tankyrase (TNKS-1/2) inhibitor on mechanical stress-induced gene expression in human chondrocytes and examined TNKS-1/2 expression in human osteoarthritis (OA) cartilage. Cells were seeded onto stretch chambers and incubated with or without a TNKS-1/2 inhibitor (XAV939) for 12 h. Uni-axial cyclic tensile strain (CTS) (0.5 Hz, 8% elongation, 30 min) was applied and the gene expression of type II collagen a1 chain (COL2A1), aggrecan (ACAN), SRY-box9 (SOX9), TNKS-1/2, a disintegrin and metalloproteinase with thrombospondin motifs-5 (ADAMTS-5), and matrix metalloproteinase-13 (MMP-13) were examined by real-time PCR. The expression of ADAMTS-5, MMP-13, nuclear translocation of nuclear factor-κB (NF-κB), and β-catenin were examined by immunocytochemistry and Western blotting. The concentration of IL-1β in the supernatant was examined by enzyme-linked immunosorbent assay (ELISA). TNKS-1/2 expression was assessed by immunohistochemistry in human OA cartilage obtained at the total knee arthroplasty. TNKS-1/2 expression was increased after CTS. The expression of anabolic factors were decreased by CTS, however, these declines were abrogated by XAV939. XAV939 suppressed the CTS-induced expression of catabolic factors, the release of IL-1β, as well as the nuclear translocation of NF-κB and β-catenin. TNKS-1/2 expression increased in mild and moderate OA cartilage. Our results demonstrated that XAV939 suppressed mechanical stress-induced expression of catabolic proteases by the inhibition of NF-κB and activation of β-catenin, indicating that TNKS-1/2 expression might be associated with OA pathogenesis. en-copyright= kn-copyright= en-aut-name=HottaYoshifumi en-aut-sei=Hotta en-aut-mei=Yoshifumi 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=YoshidaAki en-aut-sei=Yoshida en-aut-mei=Aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=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=NaniwaShuichi en-aut-sei=Naniwa en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShimizuNoriyuki en-aut-sei=Shimizu en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IchikawaChinatsu en-aut-sei=Ichikawa en-aut-mei=Chinatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=LinDeting en-aut-sei=Lin en-aut-mei=Deting kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujiwaraTomohiro en-aut-sei=Fujiwara en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Locomotive Pain Center, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University 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 University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=osteoarthritis kn-keyword=osteoarthritis en-keyword=chondrocyte kn-keyword=chondrocyte en-keyword=mechanical stress kn-keyword=mechanical stress en-keyword=tankyrases kn-keyword=tankyrases en-keyword=XAV939 kn-keyword=XAV939 en-keyword=SOX9 kn-keyword=SOX9 en-keyword=ADAMTS-5 kn-keyword=ADAMTS-5 en-keyword=MMP-13 kn-keyword=MMP-13 en-keyword=IL-1β kn-keyword=IL-1β en-keyword=NF-κB kn-keyword=NF-κB en-keyword=β-catenin kn-keyword=β-catenin END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=47 end-page=52 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-Term Follow-up Data of a Multi-Institutional Phase-2 Study of S-1/oxaliplatin and Bevacizumab Therapy in Patients with Advanced Colorectal Cancer: The HiSCO-02 Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Oral fluoropyrimidines (FUs) have certain advantages over intravenous FUs, such as longer intervals between outpatient visits, no requirement for central venous port (CVP) implantation, and lower incidence of neutropenia. We previously reported the efficacy of S-1/oxaliplatin (SOX) with bevacizumab therapy as a first-line treatment for advanced colorectal cancer (CRC) in a prospective phase-II multi-institutional clinical trial (HiSCO-02 study). However, our prognostic data at the time lacked a sufficient observation period. Herein, we analyze the longer-term follow-up data, focusing on the status of eventual CVP implantation via an open-label, non-randomized, multicenter study. This study enrolled 55 patients (mean age, 64 years), of whom 43 died (41 of primary cancer). The median overall survival was 22.7 months (95% CI: 20.1-34.7 months). Post-treatment regimens after failure of first-line treatment were initiated in 43 patients; CPT11-based regimens were selected in most cases, and other oral FU combinations in nine. CVP was implanted in 35 patients prior to first-line treatment; eleven of the remaining 20 patients did not require CVP implantation. In conclusion, we report here the final prognostic update of the Phase II clinical trial examining the efficacy of SOX plus bevacizumab therapy, the results of which confirm the clinical efficacy of this regimen. en-copyright= kn-copyright= en-aut-name=ShimomuraManabu en-aut-sei=Shimomura en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShinozakiKatsunori en-aut-sei=Shinozaki en-aut-mei=Katsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YanoTakuya en-aut-sei=Yano en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AkabaneShintaro en-aut-sei=Akabane en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OhdanHideki en-aut-sei=Ohdan en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Hiroshima Surgical study group of Clinical Oncology (HiSCO) en-aut-sei=Hiroshima Surgical study group of Clinical Oncology (HiSCO) en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Gastroenterological and Transplant Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=2 en-affil=Division of Clinical Oncology, Hiroshima Prefectural Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterological and Transplant Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=4 en-affil=Department of Gastroenterological and Transplant Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=5 en-affil=Department of Gastroenterological and Transplant Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=6 en-affil= kn-affil= en-keyword=metastatic colorectal cancer kn-keyword=metastatic colorectal cancer en-keyword=chemotherapy kn-keyword=chemotherapy en-keyword=S-1 kn-keyword=S-1 en-keyword=prospective phase II study kn-keyword=prospective phase II study END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=29 end-page=36 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Regression of Necrotic Lesions after Methotrexate Withdrawal in Patients with Methotrexate-Associated Lymphoproliferative Disorders: A Retrospective CT Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=This retrospective study investigated whether necrotic lesions detected on a computed tomography (CT) scan are more regressive than non-necrotic lesions after methotrexate withdrawal in patients pathologically diagnosed with methotrexate-associated lymphoproliferative disorders (MTX-LPD). In total, 89 lesions extracted from 24 patients on CT scans were included in the analysis. All patients had been evaluated for the presence of necrosis within lesions via CT scan upon first suspicion of MTX-LPD (baseline CT scan). The percentage lesion size reduction between the baseline and initial follow-up CT scan was calculated. The association between necrosis within lesions and size changes was estimated via linear regression analyses using both crude and adjusted models. Necrosis was significantly more common in extranodal lesions (27 out of 30 lesions, 90%) than in nodal lesions (9 out of 59 lesions, 15%, p<0.001). In the crude model, the regression of necrotic lesions was 58.5% greater than that of non-necrotic lesions; the difference was statistically significant (p<0.001). Additionally, the longest diameter of necrotic lesions at the baseline CT scan was significantly greater than that of non-necrotic lesions (p<0.001). Based on the adjusted model, necrotic lesions showed 49.3% greater regression than non-necrotic lesions (p=0.017). Necrosis detected on a CT scan was found to be an independent predictor of regression after MTX withdrawal in patients with MTX-LPD. en-copyright= kn-copyright= en-aut-name=KitayamaTakahiro en-aut-sei=Kitayama en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakashi en-aut-sei=Tanaka en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanieYuichiro en-aut-sei=Kanie en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MarukawaYohei en-aut-sei=Marukawa en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KojimaKatsuhide en-aut-sei=Kojima en-aut-mei=Katsuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Department of Radiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama City Hospital kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Radiology, Okayama Saiseikai General Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Radiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=methotrexate kn-keyword=methotrexate en-keyword=lymphoproliferative disorder kn-keyword=lymphoproliferative disorder en-keyword=computed tomography kn-keyword=computed tomography en-keyword=necrosis kn-keyword=necrosis END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=118 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240106 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Hydrogen in Transplantation: Potential Applications and Therapeutic Implications en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hydrogen gas, renowned for its antioxidant properties, has emerged as a novel therapeutic agent with applications across various medical domains, positioning it as a potential adjunct therapy in transplantation. Beyond its antioxidative properties, hydrogen also exerts anti-inflammatory effects by modulating pro-inflammatory cytokines and signaling pathways. Furthermore, hydrogen's capacity to activate cytoprotective pathways bolsters cellular resilience against stressors. In recent decades, significant advancements have been made in the critical medical procedure of transplantation. However, persistent challenges such as ischemia-reperfusion injury (IRI) and graft rejection continue to hinder transplant success rates. This comprehensive review explores the potential applications and therapeutic implications of hydrogen in transplantation, shedding light on its role in mitigating IRI, improving graft survival, and modulating immune responses. Through a meticulous analysis encompassing both preclinical and clinical studies, we aim to provide valuable insights into the promising utility of hydrogen as a complementary therapy in transplantation. en-copyright= kn-copyright= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=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=HirayamaTakahiro en-aut-sei=Hirayama en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AgetaKohei en-aut-sei=Ageta en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AokageToshiyuki en-aut-sei=Aokage en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HisamuraMasaki en-aut-sei=Hisamura en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=hydrogen kn-keyword=hydrogen en-keyword=organ transplantation kn-keyword=organ transplantation en-keyword=ischemia reperfusion kn-keyword=ischemia reperfusion END start-ver=1.4 cd-journal=joma no-vol=113 cd-vols= no-issue= article-no= start-page=61 end-page=73 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240201 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 2023. kn-title=公表学術論文等リスト　2023 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=117 cd-vols= no-issue=1 article-no= start-page=181 end-page=188 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical Features of Patients With Second Primary Lung Cancer After Head and Neck Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background In survivors of head and neck cancer (HNC), second primary lung cancer (SPLC) often develop as a result of a common risk factor, that is, smoking. A multicenter experience was reviewed to evaluate how the history of a diagnosis of HNC affects the outcomes of patients undergoing pulmonary resection for SPLC.
Methods A multicenter retrospective analysis of patients hospitalized between January 2012 and December 2018 was performed. From a cohort of 4521 patients undergoing therapeutic pulmonary resection for primary non-small cell lung cancer, 100 patients with a previous history of HNC (HNC group) were identified. These patients were compared with a control group consisting of 200 patients without an HNC history from the same cohort pair-matched with operating facility, age, sex, and pathologic stage of lung cancer.
Results At the time of surgery for SPLC, the HNC group showed malnutrition with a lower prognostic nutritional index compared with the control group (P < .001). The HNC group was determined to have postoperative complications more frequently (P = .02). The 5-year overall survival rates in the HNC and control groups were 59.0% and 83.2%, respectively (P < .001). Statistically, HNC history, lower prognostic nutritional index, squamous cell lung cancer, and TNM stage were identified to be independently associated with poor survival.
Conclusions Patients with SPLC after primary HNC often present with malnutrition and are predisposed to postoperative complications and poor survival after pulmonary resection. en-copyright=

history in patients who undergo left atrial appendage closure en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Aim: Anticoagulant users with nonvalvular atrial fibrillation (NVAF) sometimes suffer from gastrointestinal bleeding (GIB) and have difficulty continuing the medication. Left atrial appendage closure (LAAC) has been developed for such situations. We aimed to clarify the clinical significance of a history of GIB in comparison to other factors in patients who had undergone LAAC.
Methods: From October 2019 to September 2023, patients with NVAF who underwent LAAC at our hospital were enrolled. We investigated the percentage of patients with a history of GIB who underwent LAAC and compared the incidence of post-LAAC bleeding in these patients compared to those with other factors.
Results: A total of 45 patients were included. There were 19 patients (42%) with a history of GIB who underwent LAAC. In a Kaplan–Meier analysis, the cumulative incidence of bleeding complications after LAAC was significantly higher in patients with a history of GIB in comparison to patients with other factors. There were eight cases of post-LAAC bleeding in total, and seven cases had GIB.
Conclusions: We need to recognize that GIB is a significant complication in patients who undergo LAAC. The management of GIB by gastroenterologists is essential to the success of LAAC. en-copyright= kn-copyright= en-aut-name=KikuchiTatsuya en-aut-sei=Kikuchi en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei=

kn-title=Epiretinal Membrane Impairs the Inner Retinal Layer in a Traction Force-Dependent Manner en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: To investigate the relationship between retinal traction force and impairment of the inner retinal layer in patients with epiretinal membrane (ERM).
Design: Nonrandomized, retrospective consecutive case series.
Participants: Two hundred nine eyes of 201 patients with idiopathic ERM who underwent vitrectomy for idiopathic ERM were enrolled.
Methods: Retinal folds caused by ERM were visualized using en face OCT, and the maximum depth of retinal folds within the parafovea (MDRF) was measured. Focal macular electroretinogram (ERG) was used to measure the amplitude and implicit time of each component for the ERM eyes and the normal fellow eyes. B-scan OCT images were used to measure the thicknesses of the inner nuclear layer (INL) and outer nuclear layer (ONL) + outer plexiform layer (OPL). Expression of α-smooth muscle actin (α-SMA) in surgically removed ERM specimens was quantified by reverse-transcription polymerase chain reaction.
Main Outcome Measures: We analyzed the relationship between MDRF and the relative amplitudes of focal macular ERG (affected eye/fellow eye), the relationships between MDRF and the mean INL thickness and ONL+OPL thickness, comparison of INL thickness and ONL+OPL thickness for each area when cases were classified according to MDRF localization in the ETDRS chart, and the relationship between MDRF and the relative expression of α-SMA in the ERM specimens.
Results: The MDRF significantly correlated with the relative amplitudes (affected eye/fellow eye) of b-waves and oscillatory potentials (r = −0.657, P = 0.015; r = −0.569, P = 0.042, respectively) and the mean INL thickness and ONL+OPL thickness (r = 0.604, P < 0.001; r = 0.210, P = 0.007, respectively). However, only the INL thickness progression rate was significantly correlated with the MDRF progression rate (r = 0.770, P < 0.001). On case stratification by localization of MDRF based on the ETDRS chart, in regions other than temporal regions, the INL thickness was significantly greater in regions with MDRF than in other regions. The MDRF significantly correlated with α-SMA expression in the ERM specimens (r = 0.555, P = 0.009).
Conclusions: The findings suggest that ERM impairs the inner retinal layer in a traction force-dependent manner.

Previous studies have reported that Saccharomyces cerevisiae fermentation products improved the health, growth, and faecal characteristics of preweaning calves. This study investigated the effects of adding liquefied sake lees to milk replacer on the growth performance, faecal characteristics, and blood metabolites of preweaning Japanese Black calves from 6 to 90 days of age. Twenty-four Japanese Black calves at 6 days of age were randomly assigned to one of three treatments: No liquefied sake lees (C, n = 8), 100 g/d (on a fresh matter basis) liquefied sake lees mixed with milk replacer (LS, n = 8), and 200 g/d (on a fresh matter basis) liquefied sake lees mixed with milk replacer (HS, n = 8). The intake of milk replacer and calf starter, as well as, the average daily gain did not differ between the treatments. The number of days counted with faecal score 1 in LS was higher than in HS (P < 0.05), while the number of days with diarrhoea medication in LS and C was lower than HS (P < 0.05). The faecal n-butyric acid concentration tended to be higher in LS compared to C (P = 0.060). The alpha diversity index (Chao1) was higher in HS than in C and LS at 90 days of age (P < 0.05). The principal coordinate analysis (PCoA) using weighted UniFrac distance showed that the bacterial community structures in faeces among the treatments at 90 days of age were significantly different (P < 0.05). The plasma β-hydroxybutyric acid concentration, an indicator of rumen development, was higher for LS than in C throughout the experiment (P < 0.05). These results suggested that adding liquefied sake lees up to 100 g/d (on a fresh matter basis) might promote rumen development in preweaning Japanese Black calves. en-copyright= kn-copyright= en-aut-name=KatsumataS. en-aut-sei=Katsumata en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayashiY. en-aut-sei=Hayashi en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OishiK. en-aut-sei=Oishi en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsukaharaT. en-aut-sei=Tsukahara en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=InoueR. en-aut-sei=Inoue en-aut-mei=R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ObataA. en-aut-sei=Obata en-aut-mei=A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HirookaH. en-aut-sei=Hirooka en-aut-mei=H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KumagaiH. en-aut-sei=Kumagai en-aut-mei=H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Shiga Prefectural Livestock Production Technology Promotion Center kn-affil= affil-num=3 en-affil=Department of Applied Biosciences, Graduate School of Agriculture, Kyoto University kn-affil= affil-num=4 en-affil=Kyoto Institute of Nutrition and Pathology kn-affil= affil-num=5 en-affil=Department of Applied Biological Sciences, Faculty of Agriculture, Setsunan University kn-affil= affil-num=6 en-affil=Shiga Prefectural Livestock Production Technology Promotion Center kn-affil= affil-num=7 en-affil=Department of Applied Biosciences, Graduate School of Agriculture, Kyoto University kn-affil= affil-num=8 en-affil=Department of Applied Biosciences, Graduate School of Agriculture, Kyoto University kn-affil= en-keyword=By-products kn-keyword=By-products en-keyword=Faecal microbiota kn-keyword=Faecal microbiota en-keyword=Japanese Black cattle kn-keyword=Japanese Black cattle en-keyword=Preweaning calves kn-keyword=Preweaning calves en-keyword=Saccharomyces cerevisiae kn-keyword=Saccharomyces cerevisiae END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=12 article-no= start-page=1481 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Random Mutational Analysis Targeting Residue K155 within the Transmembrane β-Hairpin of the Mosquitocidal Mpp46Ab Toxin en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mpp46Ab is a mosquito-larvicidal pore-forming toxin derived from Bacillus thuringiensis TK-E6. Pore formation is believed to be a central mode of Mpp46Ab action, and the cation selectivity of the channel pores, in particular, is closely related to its mosquito-larvicidal activity. In the present study, we constructed a mutant library in which residue K155 within the transmembrane β-hairpin was randomly replaced with other amino acid residues. Upon mutagenesis and following primary screening using Culex pipiens mosquito larvae, we obtained 15 mutants in addition to the wild-type toxin. Bioassays using purified proteins revealed that two mutants, K155E and K155I, exhibited toxicity significantly higher than that of the wild-type toxin. Although increased cation selectivity was previously reported for K155E channel pores, we demonstrated in the present study that the cation selectivity of K155I channel pores was also significantly increased. Considering the characteristics of the amino acids, the charge of residue 155 may not directly affect the cation selectivity of Mpp46Ab channel pores. Replacement of K155 with glutamic acid or isoleucine may induce a similar conformational change in the region associated with the ion selectivity of the Mpp46Ab channel pores. Mutagenesis targeting the transmembrane β-hairpin may be an effective strategy for enhancing the ion permeability of the channel pores and the resulting mosquito-larvicidal activity of Mpp46Ab. en-copyright= kn-copyright= en-aut-name=MiyazakiMidoka en-aut-sei=Miyazaki en-aut-mei=Midoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=HayakawaTohru en-aut-sei=Hayakawa en-aut-mei=Tohru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=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= en-keyword=mosquito-larvicidal toxin kn-keyword=mosquito-larvicidal toxin en-keyword=Bacillus thuringiensis TK-E6 kn-keyword=Bacillus thuringiensis TK-E6 en-keyword=Culex pipiens mosquito larvae kn-keyword=Culex pipiens mosquito larvae en-keyword=site-directed mutagenesis kn-keyword=site-directed mutagenesis en-keyword=electrophysiologic analysis kn-keyword=electrophysiologic analysis END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=6 article-no= start-page=595 end-page=605 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Concomitant Use of Multiple Nephrotoxins including Renal Hypoperfusion Medications Causes Vancomycin-Associated Nephrotoxicity: Combined Retrospective Analyses of Two Real-World Databases en-subtitle= kn-subtitle= en-abstract= kn-abstract=There is a growing concern about the relationship between vancomycin-associated nephrotoxicity (VAN) and concomitant use of nephrotoxins. We examined this relationship by combined retrospective analyses of two real-world databases. Initially, the FDA Adverse Event Reporting System (FAERS) was analyzed for the effects of concomitant use of one or more nephrotoxins on VAN and the types of combinations of nephrotoxins that exacerbate VAN. Next, electronic medical records (EMRs) of patients who received vancomycin (VCM) at Tokushima University Hospital between January 2006 and March 2019 were examined to confirm the FAERS analysis. An elevated reporting odds ratio (ROR) was observed with increases in the number of nephrotoxins administered (VCM + one nephrotoxin, adjusted ROR (95% confidence interval [CI]) 1.67 [1.51-1.85]; VCM + ≥2 nephrotoxins, adjusted ROR [95% CI] 1.54 [1.37-1.73]) in FAERS. EMRs analysis showed that the number of nephrotoxins was associated with higher incidences of VAN [odds ratio: 1.99; 95% CI: 1.42-2.78]. Overall, concomitant use of nephrotoxins was associated with an increased incidence of VAN, especially when at least one of those nephrotoxins was a renal hypoperfusion medication (furosemide, non-steroidal anti-inflammatory drugs, and vasopressors). The concomitant use of multiple nephrotoxins, especially including renal hypoperfusion medication, should be avoided to prevent VAN. en-copyright= kn-copyright= en-aut-name=BandoTakashi

For example, epidermal keratinocytes are capable of recognizing various cytokines and pathogen-associated molecular pattern, and producing a wide variety of inflammatory cytokines, chemokines, and antimicrobial peptides. Previous basic studies have shown that the immune response of epidermal keratinocytes has a significant impact on inflammatory skin diseases. The purpose of this review is to provide foundation of knowledge on the cytokines which are recognized or produced by epidermal keratinocytes. Since a number of biologics for skin diseases have appeared, it is necessary to fully understand the relationship between epidermal keratinocytes and the cytokines. In this review, the cytokines recognized by epidermal keratinocytes are specifically introduced as "input cytokines", and the produced cytokines as "output cytokines". Furthermore, we also refer to the existence of biologics against those input and output cytokines, and the target skin diseases. These use results demonstrate how important targeted cytokines are in real skin diseases, and enhance our understanding of the cytokines. en-copyright= kn-copyright= en-aut-name=MorizaneShin en-aut-sei=Morizane en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MukaiTomoyuki en-aut-sei=Mukai en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SunagawaKo en-aut-sei=Sunagawa en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TachibanaKota en-aut-sei=Tachibana en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawakamiYoshio en-aut-sei=Kawakami en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OuchidaMamoru en-aut-sei=Ouchida en-aut-mei=Mamoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Immunology and Molecular Genetics, Kawasaki Medical School kn-affil= affil-num=3 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Molecular Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=epidermal keratinocytes kn-keyword=epidermal keratinocytes en-keyword=input cytokines kn-keyword=input cytokines en-keyword=output cytokines kn-keyword=output cytokines en-keyword=biologics kn-keyword=biologics en-keyword=inflammatory skin diseases kn-keyword=inflammatory skin diseases END start-ver=1.4 cd-journal=joma no-vol=1821 cd-vols= no-issue= article-no= start-page=148565 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231215 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Injection of exogenous amyloid-β oligomers aggravated cognitive deficits, and activated necroptosis, in APP23 transgenic mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Alzheimer's disease (AD) is a neurodegenerative disease that is characterized by the loss of synapses and neurons in the brain, and the accumulation of amyloid plaques. Aβ oligomers (AβO) play a critical role in the pathogenesis of AD. Although there is increasing evidence to support the involvement of necroptosis in the pathogenesis of AD, the exact mechanism remains elusive. In the present study, we explored the effect of exogenous AβO injection on cell necroptosis and cognitive deficits in APP23 transgenic mice. We found that intrahippocampal injection of AβO accelerated the development of AD pathology and caused cognitive impairment in APP23 mice. Specifically, AβO injection significantly accelerated the accumulation of AβO and increased the expression level of phosphorylated-tau, and also induced necroptosis. Behavioral tests showed that AβO injection was associated with cognitive impairment. Furthermore, necroptosis induced by AβO injection occurred predominantly in microglia of the AD brain. We speculate that AβO increased necroptosis by activating microglia, resulting in cognitive deficits. Our results may aid in an understanding of the role played by AβO in AD from an alternative perspective and provide new ideas and evidence for necroptosis as a potential intervention and therapeutic target for AD. en-copyright= kn-copyright= en-aut-name=YuHaibo en-aut-sei=Yu en-aut-mei=Haibo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoriharaRyuta en-aut-sei=Morihara en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Ota-ElliottRicardo en-aut-sei=Ota-Elliott en-aut-mei=Ricardo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BianZhihong en-aut-sei=Bian en-aut-mei=Zhihong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BianYuting en-aut-sei=Bian en-aut-mei=Yuting kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HuXinran en-aut-sei=Hu en-aut-mei=Xinran kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SunHongming en-aut-sei=Sun en-aut-mei=Hongming kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FukuiYusuke en-aut-sei=Fukui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AbeKoji en-aut-sei=Abe en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IshiuraHiroyuki en-aut-sei=Ishiura en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YamashitaToru en-aut-sei=Yamashita en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=National Center Hospital, National Center of Neurology and Psychiatry kn-affil= affil-num=10 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Alzheimer's disease (AD) kn-keyword=Alzheimer's disease (AD) en-keyword=Amyloid-13 oligomers (A13O) kn-keyword=Amyloid-13 oligomers (A13O) en-keyword=Necroptosis kn-keyword=Necroptosis en-keyword=Microglia kn-keyword=Microglia en-keyword=Neurodegeneration kn-keyword=Neurodegeneration END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=1279699 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230928 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=FZL, a dynamin-like protein localized to curved grana edges, is required for efficient photosynthetic electron transfer in Arabidopsis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photosynthetic electron transfer and its regulation processes take place on thylakoid membranes, and the thylakoid of vascular plants exhibits particularly intricate structure consisting of stacked grana and flat stroma lamellae. It is known that several membrane remodeling proteins contribute to maintain the thylakoid structure, and one putative example is FUZZY ONION LIKE (FZL). In this study, we re-evaluated the controversial function of FZL in thylakoid membrane remodeling and in photosynthesis. We investigated the sub-membrane localization of FZL and found that it is enriched on curved grana edges of thylakoid membranes, consistent with the previously proposed model that FZL mediates fusion of grana and stroma lamellae at the interfaces. The mature fzl thylakoid morphology characterized with the staggered and less connected grana seems to agree with this model as well. In the photosynthetic analysis, the fzl knockout mutants in Arabidopsis displayed reduced electron flow, likely resulting in higher oxidative levels of Photosystem I (PSI) and smaller proton motive force (pmf). However, nonphotochemical quenching (NPQ) of chlorophyll fluorescence was excessively enhanced considering the pmf levels in fzl, and we found that introducing kea3-1 mutation, lowering pH in thylakoid lumen, synergistically reinforced the photosynthetic disorder in the fzl mutant background. We also showed that state transitions normally occurred in fzl, and that they were not involved in the photosynthetic disorders in fzl. We discuss the possible mechanisms by which the altered thylakoid morphology in fzl leads to the photosynthetic modifications. en-copyright= kn-copyright= en-aut-name=OgawaYu en-aut-sei=Ogawa en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwanoMegumi en-aut-sei=Iwano en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShikanaiToshiharu en-aut-sei=Shikanai en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakamotoWataru en-aut-sei=Sakamoto en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Biostudies, Kyoto University kn-affil= affil-num=3 en-affil=Department of Botany, Graduate School of Science, Kyoto University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=FUZZY ONION LIKE (FZL) kn-keyword=FUZZY ONION LIKE (FZL) en-keyword=Arabidopsis kn-keyword=Arabidopsis en-keyword=chloroplast kn-keyword=chloroplast en-keyword=thylakoid kn-keyword=thylakoid en-keyword=thylakoid structure kn-keyword=thylakoid structure en-keyword=photosynthetic electron transfer kn-keyword=photosynthetic electron transfer 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=77 cd-vols= no-issue=5 article-no= start-page=511 end-page=516 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=Associations among Preoperative Malnutrition, Muscle Loss, and Postoperative Walking Ability in Intertrochanteric Fractures: A Retrospective Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sarcopenia and malnutrition are increasing in older adults and are reported risk factors for functional impairment after hip fracture surgery. This study aimed to investigate the associations between skeletal muscle mass loss, malnutrition, and postoperative walking ability in patients with hip fracture. We retrospectively reviewed patients who underwent intertrochanteric fracture surgery at our institute. The psoas muscle index, controlling nutritional status score, and functional ambulation category (FAC) were used to evaluate skeletal muscle mass, nutritional status, and walking ability, respectively. Six months after surgery, walking ability was assessed as either “gait disturbance” or “independent gait”. Multivariate binomial logistic regression analysis, with skeletal muscle mass, nutritional status, and other factors, was used to predict the risk of being assigned to the gait disturbance group. This study included 95 patients (mean age, 85.2 years; 70 women). Sixty-six patients had low skeletal muscle mass, 35 suffered from malnutrition, and 28 had both. Malnutrition and low skeletal muscle mass were significantly associated with postoperative gait disturbance (FAC < 3). Preoperative low skeletal muscle mass and malnutrition were risk factors for postoperative poor walking ability. Further preventive interventions focusing on skeletal muscle mass and nutritional status are required. en-copyright= kn-copyright= en-aut-name=SatoKohei en-aut-sei=Sato en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujiHironori en-aut-sei=Tsuji en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YorimitsuMasanori en-aut-sei=Yorimitsu en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UeharaTakenori en-aut-sei=Uehara en-aut-mei=Takenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakaoShinichiro en-aut-sei=Takao en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HataToshiaki en-aut-sei=Hata en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FukuokaShiro en-aut-sei=Fukuoka en-aut-mei=Shiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NodaTomoyuki en-aut-sei=Noda en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KandaHideyuki en-aut-sei=Kanda en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Japanese Red Cross Okayama Hospital kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Tsuyama Chuo Hospital kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Okayama Medical Center kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery, Kawasaki Medical School, General Medical Center kn-affil= affil-num=10 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=sarcopenia kn-keyword=sarcopenia en-keyword=nutrition kn-keyword=nutrition en-keyword=geriatric hip fracture kn-keyword=geriatric hip fracture en-keyword=psoas muscle index kn-keyword=psoas muscle index en-keyword=controlling nutritional status score kn-keyword=controlling nutritional status score END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=5 article-no= start-page=461 end-page=469 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=Relationship between the Hip Abductor Muscles and Abduction Strength in Patients with Hip Osteoarthritis en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to determine which muscle the gluteus maximus, gluteus medius, gluteus minimus (Gmin), or tensor fasciae latae (TFL) contributes most to hip abduction strength and to identify effective sites for cross-sectional area (CSA) Gmin and TFL measurement in hip osteoarthritis (OAhip) patients. Twenty-eight patients with OAhip were included. The muscle CSA and volume were determined using magnetic resonance imaging. Peak isometric strength was determined using hand-held dynamometry. Muscle volumes were normalized to the total muscle volume of hip abductors. Multiple regression analysis was performed. The difference between the CSA of Gmin and TFL was calculated, and correlations with volume and muscle strength were determined. Gmin volume was related to abductor muscle strength (p=0.042). The peak CSA of the Gmin correlated with muscle volume and strength. The CSA of the TFL correlated with volume, with no difference between the CSA of the most protruding part of the lesser trochanter and peak CSA. Gmin volume was strongly related to abductor muscle strength. Peak CSA is a useful parameter for assessing the CSA of the Gmin among patients with OAhip. The CSA of the TFL should be measured at the most protruding part of the lesser trochanter. en-copyright= kn-copyright= en-aut-name=HommaDaisuke en-aut-sei=Homma en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MinatoIzumi en-aut-sei=Minato en-aut-mei=Izumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ImaiNorio en-aut-sei=Imai en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyasakaDai en-aut-sei=Miyasaka en-aut-mei=Dai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakaiYoshinori en-aut-sei=Sakai en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HorigomeYoji en-aut-sei=Horigome en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuzukiHayato en-aut-sei=Suzuki en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=DohmaeYoichiro en-aut-sei=Dohmae en-aut-mei=Yoichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=EndoNaoto en-aut-sei=Endo en-aut-mei=Naoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Division of Orthopaedic Surgery, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=2 en-affil=Division of Orthopaedic Surgery, Niigata Rinko Hospital kn-affil= affil-num=3 en-affil=Division of Comprehensive Musculoskeletal Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=4 en-affil=Division of Orthopaedic Surgery, Niigata Bandai Hospital kn-affil= affil-num=5 en-affil=Division of Orthopaedic Surgery, Niigata City General Hospital kn-affil= affil-num=6 en-affil=Division of Comprehensive Musculoskeletal Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=7 en-affil=Division of Orthopaedic Surgery, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=8 en-affil=Division of Orthopaedic Surgery, Niigata Bandai Hospital kn-affil= affil-num=9 en-affil=Division of Orthopaedic Surgery, Niigata Prefectural Tsubame Rosai Hospital kn-affil= en-keyword=gluteus minimus kn-keyword=gluteus minimus en-keyword=tensor fasciae latae kn-keyword=tensor fasciae latae en-keyword=cross-sectional area kn-keyword=cross-sectional area en-keyword=muscle volume kn-keyword=muscle volume en-keyword=hip osteoarthritis kn-keyword=hip osteoarthritis END start-ver=1.4 cd-journal=joma no-vol=34 cd-vols= no-issue=2 article-no= start-page=373 end-page=381 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220420 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of a Spiral Shaped Soft Holding Actuator Using Extension Type Flexible Pneumatic Actuators en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recently, several pneumatic soft actuators have been applied to wearable and welfare devices to provide nursing care and physical support for the elderly and disabled. In this study, as a wearable soft actuator for holding body, a spiral shaped soft holding actuator that can wrap a user according to their body shape was proposed and tested. The construction and operating principle of the tested soft actuator with circumferential restraint mechanism using three extension type flexible pneumatic actuators (EFPAs) has been discussed. As a result, it was found that the tested actuator could hold elbows and knees when the joint is in motion. An analytical model of the spiral actuator was also proposed to achieve an optimal design. It can be confirmed that the proposed analytical model can predict the shape of the actuator when various EFPAs are pressurized. en-copyright= kn-copyright= en-aut-name=ShimookaSo en-aut-sei=Shimooka en-aut-mei=So kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AkagiTetsuya en-aut-sei=Akagi en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DohtaShujiro en-aut-sei=Dohta en-aut-mei=Shujiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShinoharaTakashi en-aut-sei=Shinohara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobayashiTakumi en-aut-sei=Kobayashi en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Intelligent Mechanical Engineering, Okayama University of Science kn-affil= affil-num=3 en-affil=Department of Intelligent Mechanical Engineering, Okayama University of Science kn-affil= affil-num=4 en-affil=Design and Manufacturing Center, Organization for Research Development and Outreach, Okayama University of Science kn-affil= affil-num=5 en-affil=Department of Intelligent Mechanical Engineering, Okayama University of Science kn-affil= en-keyword=spiral shaped soft holding actuator kn-keyword=spiral shaped soft holding actuator en-keyword=extension type flexible pneumatic actuator kn-keyword=extension type flexible pneumatic actuator en-keyword=circumference restraint mechanism kn-keyword=circumference restraint mechanism en-keyword=analytical model kn-keyword=analytical model END start-ver=1.4 cd-journal=joma no-vol=81 cd-vols= no-issue=1 article-no= start-page=58 end-page=67 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220309 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Improvement of anterior disc displacement on the mandibular deviated side after intraoral vertical ramus osteotomy in a patient with facial asymmetry: a case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: We present the orthognathic treatment of an adult skeletal Class III patient with facial asymmetry, mandibular rightward deviation, and anterior disc displacement without reduction (ADDwoR) at the right temporomandibular joint (TMJ) by intraoral vertical ramus osteotomy (IVRO).
Materials and methods: The patient was a 23-year-old man with complaints of mandibular deviation and crowded lower anterior teeth, resulting in facial asymmetry. The maxillary position was normal with protrusion and rightward deviation of the mandible. There was no cant of the maxilla. He experienced pain in the right TMJ during mastication, and Magnetic resonance imaging (MRI) revealed an ADDwoR on the right side. The patient was diagnosed with Class III malocclusion, skeletal Class III prognathism with mandibular deviation, and ADDwoR on the right side. Orthognathic surgery was proposed for jaw deformity, and IVRO was performed to correct mandibular deviation.
Results: One year and 2 months after treatment onset, IVRO was performed with differential setback: 2 mm on the right and 8 mm on the left side of the mandible. The midline of the lower dentition was rotated by 6 mm to coincide with the facial midline. Symptoms of temporomandibular disorders were not observed post-operatively. Active-treatment period was for 31 months. MRI findings showed improvement in anterior disc displacement on the right side during the post-retention.
Conclusion: In the case of facial asymmetry with anterior disc displacement on the mandibular deviated side, IVRO was suggested to have a potential effect on the positional relationship between the mandibular head and temporomandibular disc. en-copyright= kn-copyright= en-aut-name=UedaHirotaka en-aut-sei=Ueda en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkaNaoki en-aut-sei=Oka en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimoTsuyoshi en-aut-sei=Shimo en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SasakiAkira en-aut-sei=Sasaki en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamashiroTakashi en-aut-sei=Yamashiro en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KamiokaHiroshi en-aut-sei=Kamioka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Orthodontics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthodontics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Division of Reconstructive Surgery for Oral and Maxillofacial Region, Department of Human Biology and Pathophysiology, School of Dentistry, Health Sciences University of Hokkaido kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthodontics and Dentofacial Orthopedics, Osaka University Graduate School of Dentistry kn-affil= affil-num=6 en-affil=Department of Orthodontics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Facial asymmetry kn-keyword=Facial asymmetry en-keyword=mandibular deviation kn-keyword=mandibular deviation en-keyword=anterior disc displacement kn-keyword=anterior disc displacement en-keyword=temporomandibular disorders kn-keyword=temporomandibular disorders en-keyword=intraoral vertical ramus osteotomy kn-keyword=intraoral vertical ramus osteotomy END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=4 article-no= start-page=429 end-page=431 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=An Unusual Presentation of Chest Pain and Laryngeal Discomfort in a Pregnant Woman: A Case Report and Literature Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Intramural esophageal dissection (IED), characterized by bleeding into the submucosal space, leads to mucosal separation and dissection. The most prevalent symptoms are sudden chest or retrosternal pain, hematemesis, and dysphagia. Therefore, acute coronary syndrome and aortic dissection are among its most notable differential diagnoses. A 31-year-old pregnant woman presented with acute chest pain, laryngeal discomfort, and hematemesis. Emergency esophagogastroscopy revealed longitudinal mucosal dissection (upper esophagus to esophagogastric junction). The patient was successfully treated by avoiding the ingestion of solid foods. Clinicians should consider a diagnosis of IED for pregnant patients with acute chest pain, especially if hematemesis is present. en-copyright= kn-copyright= en-aut-name=SasanamiMisa en-aut-sei=Sasanami en-aut-mei=Misa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IidaAtsuyoshi en-aut-sei=Iida en-aut-mei=Atsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiraiRyousuke en-aut-sei=Hirai en-aut-mei=Ryousuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ObaraTakashi en-aut-sei=Obara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University 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 Gastroenterology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=chest pain kn-keyword=chest pain en-keyword=dysphagia kn-keyword=dysphagia en-keyword=esophageal dissection kn-keyword=esophageal dissection en-keyword=hematemesis kn-keyword=hematemesis END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=12 article-no= start-page=1927 end-page=1949 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Enhanced Production of EPA-Derived Anti-Inflammatory Metabolites after Oral Administration of a Novel Self-Emulsifying Highly Purified EPA Ethyl Ester Formulation (MND-2119) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims: MND-2119 is a novel once-daily dose self-emulsifying formulation of highly purified eicosapentaenoic acid ethyl ester (EPA-E) and is approved as an antihyperlipidemia agent in Japan. It has improved absorption and achieves higher plasma EPA concentrations at Cmax than conventional EPA-E. In the JELIS trial, concomitant use of EPA-E with statin therapy significantly reduced atherosclerotic cardiovascular disease (ASCVD) risks. As a potential mechanism of action of EPA, endogenous formation of EPA-derived anti-inflammatory metabolites is receiving greater attention. This study aims to investigate the endogenous formation of EPA-derived anti-inflammatory metabolites following single and multiple administrations of MND-2119.
Methods: Healthy adult male subjects were randomly assigned to a nonintervention (control) group, MND-2119 2-g/day group, MND-2119 4-g/day group, or EPA-E 1.8-g/day group for 7 days (N=8 per group). Plasma fatty acids and EPA-derived metabolites were evaluated. Peripheral blood neutrophils were isolated, and the production of EPA-derived metabolites from in vitro stimulated neutrophils was evaluated.
Results: After single and multiple administrations of MND-2119 2 g/day, there were significant increases in plasma EPA concentration, 18-hydroxyeicosapentaenoic acid (18-HEPE), and 17,18-epoxyeicosatetraenoic acid compared with those of EPA-E 1.8 g/day. They were further increased with MND-2119 4 g/day administration. In neutrophils, the EPA concentration in the MND-2119 2-g/day group was significantly higher compared with that in the EPA-E 1.8-g/day group after multiple administration, and 18-HEPE production was positively correlated with EPA concentration. No safety issues were noted.
Conclusions: These results demonstrate that MND-2119 increases the plasma and cellular concentrations of EPA and EPA-derived metabolites to a greater extent than conventional EPA-E formulations. en-copyright= kn-copyright= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaoeSatoko en-aut-sei=Naoe en-aut-mei=Satoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WakabayashiHiroyuki en-aut-sei=Wakabayashi en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YanoTakashi en-aut-sei=Yano en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MoriTakuya en-aut-sei=Mori en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KandaShingo en-aut-sei=Kanda en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AritaMakoto en-aut-sei=Arita en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Medical Affairs Department, Mochida Pharmaceutical Co., Ltd. kn-affil= affil-num=3 en-affil=Medical Affairs Department, Mochida Pharmaceutical Co., Ltd. kn-affil= affil-num=4 en-affil=Medical Affairs Department, Mochida Pharmaceutical Co., Ltd. kn-affil= affil-num=5 en-affil=Clinical Research Department, Mochida Pharmaceutical Co., Ltd. kn-affil= affil-num=6 en-affil=Clinical Development Planning and Management Department, Mochida Pharmaceutical Co., Ltd. kn-affil= affil-num=7 en-affil=Laboratory for Metabolomics, RIKEN Center for Integrative Medical Sciences kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Eicosapentaenoic acid kn-keyword=Eicosapentaenoic acid en-keyword=MND-2119 kn-keyword=MND-2119 en-keyword=Metablolite kn-keyword=Metablolite en-keyword=Inflammation kn-keyword=Inflammation END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=11676 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230719 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness of deep learning classifiers in histopathological diagnosis of oral squamous cell carcinoma by pathologists en-subtitle= kn-subtitle= en-abstract= kn-abstract=The study aims to identify histological classifiers from histopathological images of oral squamous cell carcinoma using convolutional neural network (CNN) deep learning models and shows how the results can improve diagnosis. Histopathological samples of oral squamous cell carcinoma were prepared by oral pathologists. Images were divided into tiles on a virtual slide, and labels (squamous cell carcinoma, normal, and others) were applied. VGG16 and ResNet50 with the optimizers stochastic gradient descent with momentum and spectral angle mapper (SAM) were used, with and without a learning rate scheduler. The conditions for achieving good CNN performances were identified by examining performance metrics. We used ROCAUC to statistically evaluate diagnostic performance improvement of six oral pathologists using the results from the selected CNN model for assisted diagnosis. VGG16 with SAM showed the best performance, with accuracy = 0.8622 and AUC = 0.9602. The diagnostic performances of the oral pathologists statistically significantly improved when the diagnostic results of the deep learning model were used as supplementary diagnoses (p-value = 0.031). By considering the learning results of deep learning model classifiers, the diagnostic accuracy of pathologists can be improved. This study contributes to the application of highly reliable deep learning models for oral pathological diagnosis. en-copyright= kn-copyright= en-aut-name=SukegawaShintaro en-aut-sei=Sukegawa en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OnoSawako en-aut-sei=Ono en-aut-mei=Sawako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaFuta en-aut-sei=Tanaka en-aut-mei=Futa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueYuta en-aut-sei=Inoue en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HaraTakeshi en-aut-sei=Hara en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshiiKazumasa en-aut-sei=Yoshii en-aut-mei=Kazumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 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=9 ORCID= en-aut-name=KatsumitsuShimada en-aut-sei=Katsumitsu en-aut-mei=Shimada kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NakaiFumi en-aut-sei=Nakai en-aut-mei=Fumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NakaiYasuhiro en-aut-sei=Nakai en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MiyazakiRyo en-aut-sei=Miyazaki en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MurakamiSatoshi en-aut-sei=Murakami en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 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=15 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=16 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 Pathology, Kagawa Prefectural Central Hospital kn-affil= affil-num=3 en-affil=Department of Electrical, Electronic and Computer Engineering, Faculty of Engineering, Gifu University kn-affil= affil-num=4 en-affil=Department of Electrical, Electronic and Computer Engineering, Faculty of Engineering, Gifu University kn-affil= affil-num=5 en-affil=Department of Electrical, Electronic and Computer Engineering, Faculty of Engineering, Gifu University kn-affil= affil-num=6 en-affil=Department of Electrical, Electronic and Computer Engineering, Faculty of Engineering, Gifu 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 Oral Pathology, Graduate School of Oral Medicine, Matsumoto Dental University kn-affil= affil-num=11 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=12 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=13 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=14 en-affil=Department of Oral Pathology, Graduate School of Oral Medicine, Matsumoto Dental University kn-affil= affil-num=15 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=16 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Faculty of Medicine kn-affil= 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.

report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background　In Japan, about 6% of esophageal cancers are adenocarcinomas, although most of them arise from Barrett's epithelium. Adenocarcinoma arising from heterotopic gastric mucosa (HGM) is very rare. Due to its rarity, there is no unified view on its treatment strategy and prognosis.
Case presentation　A 57-year-old man presented with a protruding lesion in the cervicothoracic esophagus that was detected by an upper gastrointestinal series at a medical checkup. Esophagoscopy revealed a 30 mm Type 1 tumor circumferentially surrounded by widespread HGM. Computed tomography (CT) and fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT showed no metastasis or invasion of the surrounding organs. We diagnosed the lesion as cT2N0M0 cStageIIB [Union for International Cancer Control (UICC) 8th Ed] cancer and performed subtotal esophagectomy with three-field lymph node dissection. The tumor was determined to be a well-differentiated adenocarcinoma arising from HGM, with deep invasion of the submucosa. The patient underwent no adjuvant therapy and has currently survived without any evidence of recurrence for 15 months.
Conclusions　Although the treatment for adenocarcinoma arising from HGM is basically the same as that for squamous cell carcinoma (SCC) of the esophagus, it is important to determine the treatment strategy based on the characteristics of the adenocarcinoma arising from HGM. en-copyright= kn-copyright= en-aut-name=NogiShohei en-aut-sei=Nogi en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=HashimotoMasashi en-aut-sei=Hashimoto en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatoTakuya en-aut-sei=Kato en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaedaNaoaki en-aut-sei=Maeda en-aut-mei=Naoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 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=8 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 Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Heterotopic gastric mucosa kn-keyword=Heterotopic gastric mucosa en-keyword=Esophagus kn-keyword=Esophagus en-keyword=Adenocarcinoma kn-keyword=Adenocarcinoma END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=13 article-no= start-page=2941 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230628 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Adrenomedullin Enhances Mouse Gustatory Nerve Responses to Sugars via T1R-Independent Sweet Taste Pathway en-subtitle= kn-subtitle= en-abstract= kn-abstract=On the tongue, the T1R-independent pathway (comprising glucose transporters, including sodium-glucose cotransporter (SGLT1) and the K-ATP channel) detects only sugars, whereas the T1R-dependent (T1R2/T1R3) pathway can broadly sense various sweeteners. Cephalic-phase insulin release, a rapid release of insulin induced by sensory signals in the head after food-related stimuli, reportedly depends on the T1R-independent pathway, and the competitive sweet taste modulators leptin and endocannabinoids may function on these two different sweet taste pathways independently, suggesting independent roles of two oral sugar-detecting pathways in food intake. Here, we examined the effect of adrenomedullin (ADM), a multifunctional regulatory peptide, on sugar sensing in mice since it affects the expression of SGLT1 in rat enterocytes. We found that ADM receptor components were expressed in T1R3-positive taste cells. Analyses of chorda tympani (CT) nerve responses revealed that ADM enhanced responses to sugars but not to artificial sweeteners and other tastants. Moreover, ADM increased the apical uptake of a fluorescent D-glucose derivative into taste cells and SGLT1 mRNA expression in taste buds. These results suggest that the T1R-independent sweet taste pathway in mouse taste cells is a peripheral target of ADM, and the specific enhancement of gustatory nerve responses to sugars by ADM may contribute to caloric sensing and food intake. en-copyright= kn-copyright= en-aut-name=IwataShusuke en-aut-sei=Iwata en-aut-mei=Shusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshidaRyusuke en-aut-sei=Yoshida en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakaiShingo en-aut-sei=Takai en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SanematsuKeisuke en-aut-sei=Sanematsu en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShigemuraNoriatsu en-aut-sei=Shigemura en-aut-mei=Noriatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NinomiyaYuzo en-aut-sei=Ninomiya en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Section of Oral Neuroscience, Graduate School of Dental Science, Kyushu University kn-affil= affil-num=2 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Section of Oral Neuroscience, Graduate School of Dental Science, Kyushu University kn-affil= affil-num=4 en-affil=Section of Oral Neuroscience, Graduate School of Dental Science, Kyushu University kn-affil= affil-num=5 en-affil=Section of Oral Neuroscience, Graduate School of Dental Science, Kyushu University kn-affil= affil-num=6 en-affil=Department of Oral Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=taste kn-keyword=taste en-keyword=sweet taste kn-keyword=sweet taste en-keyword=taste receptor family 1 members 2 and 3 kn-keyword=taste receptor family 1 members 2 and 3 en-keyword=sodium-glucose cotransporter 1 kn-keyword=sodium-glucose cotransporter 1 en-keyword=adrenomedullin kn-keyword=adrenomedullin en-keyword=caloric sensing kn-keyword=caloric sensing END start-ver=1.4 cd-journal=joma no-vol=37 cd-vols= no-issue=11 article-no= start-page=e15077 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230717 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Percentage of low attenuation area on computed tomography detects chronic lung allograft dysfunction, especially bronchiolitis obliterans syndrome, after bilateral lung transplantation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: The percentage of low attenuation area (%LAA) on computed tomography (CT) is useful for evaluating lung emphysema, and higher %LAA was observed in patients with chronic lung allograft dysfunction (CLAD). This study investigated the relationship between the %LAA and the development of CLAD after bilateral lung transplantation (LT).
Methods: We conducted a single-center retrospective study of 75 recipients who underwent bilateral LT; the recipients were divided into a CLAD group (n = 30) and a non-CLAD group (n = 45). The %LAA was calculated using CT and compared between the two groups from 4 years before to 4 years after the diagnosis of CLAD. The relationships between the %LAA and the percent baseline values of the pulmonary function test parameters were also calculated.
Results: The %LAA was significantly higher in the CLAD group than in the non-CLAD group from 2 years before to 2 years after the diagnosis of CLAD (P < .05). In particular, patients with bronchiolitis obliterans syndrome (BOS) exhibited significant differences even from 4 years before to 4 years after diagnosis (P < .05). Significant negative correlations between the %LAA and the percent baseline values of the forced expiratory volume in 1 s (r = −.36, P = .0031), the forced vital capacity (r = −.27, P = .027), and the total lung capacity (r = −.40, P < .001) were seen at the time of CLAD diagnosis.
Conclusion: The %LAA on CT was associated with the development of CLAD and appears to have the potential to predict CLAD, especially BOS, after bilateral LT. en-copyright= kn-copyright= en-aut-name=KuboYujiro en-aut-sei=Kubo en-aut-mei=Yujiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShiotaniToshio en-aut-sei=Shiotani en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsubaraKei en-aut-sei=Matsubara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HashimotoKohei en-aut-sei=Hashimoto en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShienKazuhiko en-aut-sei=Shien en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SuzawaKen en-aut-sei=Suzawa en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YamamotoHiromasa en-aut-sei=Yamamoto en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= en-keyword=bronchiolitis obliterans syndrome kn-keyword=bronchiolitis obliterans syndrome en-keyword=chronic lung allograft dysfunction kn-keyword=chronic lung allograft dysfunction en-keyword=computed tomography kn-keyword=computed tomography en-keyword=lung transplantation kn-keyword=lung transplantation en-keyword=restrictive allograft syndrome kn-keyword=restrictive allograft syndrome END start-ver=1.4 cd-journal=joma no-vol=34 cd-vols= no-issue=8 article-no= start-page=2955 end-page=2971 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220802 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Method for Estimating Physician Stress Using Wearable Sensor Devices en-subtitle= kn-subtitle= en-abstract= kn-abstract=The idea of Society 5.0 initiative has been proposed to solve various social problems by connecting virtual cyberspace and real physical space through information technology. When applying the idea to improve the work-life balance of physicians in the medical field, we must consider the increased stress owing to their long continuous working hours. Estimating the stress of physicians in their daily lives by the questionnaires is insufficient, because of the difficulty of accurate their activity recalling. By using bio-metric information such as heart rate, physical activity, and sleeping information, it was expected that the daily stress state of physicians with high accuracy. In this paper, we propose a method for estimating physician stress by analyzing bio-metric information acquired by wearing a wearable sensor device. The proposed method estimates the state of stress during daily activities by acquiring data on heart rate variability (HRV) during wakefulness as well as sleep depth during rapid eye movement (REM) and non-REM sleep. Up to seven physicians wore the wearable sensor device for the maximum of eight weeks and the sleep depth and low-/high-frequency (LF/HF) components of HRV were obtained. Our observation showed that physicians' root mean square of successive differences (rMSSDs) were constantly high in their healthy state. Therefore, the decreasing of this index can be used as an indicator of fatigue and stress. In addition, by combining LF/HF components to the rMSSDs, we may estimate the stress state of physicians and find personal stressors. en-copyright= kn-copyright= en-aut-name=ImuraIssei en-aut-sei=Imura en-aut-mei=Issei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GotohYusuke en-aut-sei=Gotoh en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakaiKoji en-aut-sei=Sakai en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OharaYu en-aut-sei=Ohara en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TazoeJun en-aut-sei=Tazoe en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiuraHiroshi en-aut-sei=Miura en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HirotaTatsuya en-aut-sei=Hirota en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UchiyamaAkira en-aut-sei=Uchiyama en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NomuraYoshinari en-aut-sei=Nomura en-aut-mei=Yoshinari 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=Faculty of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Radiology, Kyoto Prefectural University of Medicine kn-affil= affil-num=4 en-affil=Department of Radiology, Kyoto Prefectural University of Medicine kn-affil= affil-num=5 en-affil=Department of Radiology, Kyoto Prefectural University of Medicine kn-affil= affil-num=6 en-affil=Department of Radiology, Kyoto Prefectural University of Medicine kn-affil= affil-num=7 en-affil=Department of Radiology, Kyoto Prefectural University of Medicine kn-affil= affil-num=8 en-affil=Graduate School of Information Science and Technology, Osaka University kn-affil= affil-num=9 en-affil=Faculty of Natural Science and Technology, Okayama University kn-affil= en-keyword=heart rate variability kn-keyword=heart rate variability en-keyword=LF/HF kn-keyword=LF/HF en-keyword=Society 5.0 kn-keyword=Society 5.0 en-keyword=stress kn-keyword=stress en-keyword=wearable sensor devices kn-keyword=wearable sensor devices en-keyword=working style kn-keyword=working style END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=12 article-no= start-page=11213 end-page=11219 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230317 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of Pipetteless Paper-Based Analytical Devices with a Volume Gauge en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this work, we propose a new design for paper based analytical devices (PADs) that eliminate the need to use a micropipette for sample introduction. With this design, a PAD is equipped with a distance-based detection channel that is connected to a storage channel that indicates the volume of a sample introduced into the PAD. The analyte in the sample solution reacts with a colorimetric reagent deposited into the distance-based detection channel as the sample solution flows into the storage channel where the volume is measured. The ratio of the lengths of the detection channel and that of the storage channel (D/S ratio) are constant for a sample containing a certain concentration, which is independent of the introduced volume. Therefore, the PADs permit volume-independent quantification using a dropper instead of a micropipette because the length of the storage channel plays the role of a volume gauge to estimate the introduced sample volume. In this study, the D/S ratios obtained with a dropper were comparable to those obtained with a micropipette, which confirmed that precise volume control is unnecessary for this PAD system. The proposed PADs were applied to the determinations of iron and bovine serum albumin using bathophenanthroline and tetrabromophenol blue as colorimetric reagents, respectively. The calibration curves showed good linear relationships with coefficients of 0.989 for iron and 0.994 for bovine serum albumin, respectively. en-copyright= kn-copyright= en-aut-name=DanchanaKaewta en-aut-sei=Danchana en-aut-mei=Kaewta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwasakiHiroshi en-aut-sei=Iwasaki en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ThayawutthikunYada en-aut-sei=Thayawutthikun en-aut-mei=Yada kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaetearPhoonthawee en-aut-sei=Saetear en-aut-mei=Phoonthawee kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= affil-num=1 en-affil=Department of Chemistry, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Okayama University kn-affil= affil-num=3 en-affil=Flow Innovation-Research for Science and Technology Laboratories (FIRST Labs), Mahidol University kn-affil= affil-num=4 en-affil=Flow Innovation-Research for Science and Technology Laboratories (FIRST Labs), Mahidol University kn-affil= affil-num=5 en-affil=Department of Chemistry, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=148 cd-vols= no-issue=11 article-no= start-page=2626 end-page=2632 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=FRET probe for detecting two mutations in one EGFR mRNA en-subtitle= kn-subtitle= en-abstract= kn-abstract=Technologies for visualizing and tracking RNA are essential in molecular biology, including in disease-related fields. In this study, we propose a novel probe set (DAt-probe and T-probe) that simultaneously detects two mutations in the same RNA using fluorescence resonance energy transfer (FRET). The DAt-probe carrying the fluorophore Atto488 and the quencher Dabcyl were used to detect a cancer mutation (exon19del), and the T-probe carrying the fluorophore Tamra was used to detect drug resistance mutations (T790M) in epidermal growth factor receptor (EGFR) mRNA. These probes were designed to induce FRET when both mutations were present in the mRNA. Gel electrophoresis confirmed that the two probes could efficiently bind to the mutant mRNA. We measured the FRET ratios using wild-type and double-mutant RNAs and found a significant difference between them. Even in living cells, the FRET probe could visualize mutant RNA. As a result, we conclude that this probe set provides a method for detecting two mutations in the single EGFR mRNA via FRET. en-copyright= kn-copyright= en-aut-name=ThuMyat en-aut-sei=Thu en-aut-mei=Myat kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YanaiKouta en-aut-sei=Yanai en-aut-mei=Kouta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShigetoHajime en-aut-sei=Shigeto en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamuraShohei en-aut-sei=Yamamura en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WatanabeKazunori en-aut-sei=Watanabe en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhtsukiTakashi en-aut-sei=Ohtsuki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Health and Medical Research Institute, National Institute of Advanced Industrial Science and Technology (AIST) kn-affil= affil-num=4 en-affil=Health and Medical Research Institute, National Institute of Advanced Industrial Science and Technology (AIST) kn-affil= affil-num=5 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=3 article-no= start-page=323 end-page=330 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Utility of Comprehensive Genomic Profiling for Precise Diagnosis of Pediatric-Type Diffuse High-Grade Glioma en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the current World Health Organization classification of central nervous system tumors, comprehensive genetic and epigenetic analyses are considered essential for precise diagnosis. A 14-year-old male patient who presented with a cerebellar tumor was initially diagnosed with glioblastoma and treated with radiation and concomitant temozolomide chemotherapy after resection. During maintenance temozolomide therapy, a new contrast-enhanced lesion developed in the bottom of the cavity formed by the resection. A second surgery was performed, but the histological findings in specimens from the second surgery were different from those of the first surgery. Although genome-wide DNA methylation profiling was conducted using frozen tissue for a precise diagnosis, the proportion of tumor cells was insufficient and only normal cerebellum was observed. We then performed comprehensive genetic analysis using formalin-fixed paraffin-embedded sections, which revealed MYCN amplification without alteration of IDH1, IDH2, or Histone H3. Finally, the patient was diagnosed with pediatric-type diffuse high-grade glioma, H3-wildtype and IDH-wildtype. In conclusion, comprehensive genetic and epigenetic analysis should be considered in pediatric brain tumor cases. en-copyright= kn-copyright= en-aut-name=MakinoKeigo en-aut-sei=Makino en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshidaJoji en-aut-sei=Ishida en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiranoShuichiro en-aut-sei=Hirano en-aut-mei=Shuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SurugaYasuki en-aut-sei=Suruga en-aut-mei=Yasuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WashioKana en-aut-sei=Washio en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishidaKenji en-aut-sei=Nishida en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YanaiHiroyuki en-aut-sei=Yanai en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TomidaShuta en-aut-sei=Tomida en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Departments of Pediatrics, Okayama University Hospital kn-affil= affil-num=8 en-affil=Departments of Pathology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Departments of Pathology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=comprehensive genomic profiling kn-keyword=comprehensive genomic profiling en-keyword=pediatric brain tumor kn-keyword=pediatric brain tumor en-keyword=genome-wide DNA methylation kn-keyword=genome-wide DNA methylation en-keyword=MYCN kn-keyword=MYCN END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=3 article-no= start-page=301 end-page=309 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Associations between Comorbidities and Acute Exacerbation of Interstitial Lung Disease after Primary Lung Cancer Surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract=Acute exacerbation (AE) of interstitial lung disease (ILD) is a severe complication of lung resection in lung cancer patients with ILD (LC-ILD). This study aimed to assess the predictive value of comorbidities other than ILD for postoperative AE in patients with LC-ILD. We retrospectively evaluated 68 patients with LC-ILD who had undergone lung resection. We classified them into two groups: those who had developed postoperative AE within 30 days after resection and those who had not. We analyzed patient characteristics, high-resolution computed tomography findings, clinical data, pulmonary function, and intraoperative data. The incidence of postoperative AEs was 11.8%. In univariate analysis, performance status (PS), honeycombing, forced vital capacity (FVC), and high hemoglobin A1c (HbA1c) levels without comorbidities were significantly associated with postoperative AE. Patients were divided into two groups according to cutoff levels of those four variables as determined by receiver operating characteristic curves, revealing that the rates of patients without postoperative AE differed significantly between groups. The present results suggested that preoperative comorbidities other than ILD were not risk factors for postoperative AE in patients with LC-ILD. However, a high preoperative HbA1c level, poor PS, low FVC, and honeycombing may be associated with postoperative AE of LC-ILD. en-copyright= kn-copyright= en-aut-name=KatoTakahide en-aut-sei=Kato

on Agglomeration Behavior of Polydisperse Fine Particles in Liquid en-subtitle= kn-subtitle= en-abstract= kn-abstract=Agglomeration, coalescence and flotation of non-metallic inclusions in steel melt are effective for obtaining “clean steel.” In this study, the agglomeration and breakup behaviors of particles with a primary particle size distribution (hereinafter, polydisperse particles) in a liquid under impeller and gas stirring were compared by numerical calculations and model experiments. The particle-size-grouping (PSG) method in the numerical agglomeration model of particles was combined with a breakup term of agglomeration due to bubble bursting at the free surface. Polydisperse and monodisperse polymethylmethacrylate (PMMA) particles were used in the agglomeration experiments. The agglomeration rate of the polydisperse particles under impeller stirring was increased by an increasing energy input rate, whereas the agglomeration rate under gas stirring decreased under this condition due to the larger contribution of the breakup of agglomerated particles during bubble bursting in gas stirring. At the same energy input rate, agglomeration of polydisperse particles was larger under impeller stirring than under gas stirring. The agglomeration rate of polydisperse particles was larger than that of monodisperse particles under both impeller and gas stirring at the same energy input rate. The computational temporal changes in the total number of particles were in good agreement with the experimental results. This means that the difference in the agglomeration behaviors observed in impeller and gas stirring can be explained by the turbulent coagulation and subsequent agglomerated particle breakup in gas stirring.

In this study, 265 patients whose clinical parameters were available before radiotherapy were investigated. Methods: Age, sex, ADL, pain, the primary site, spinal level of bone metastases, spinal instability, treatment strategy, including chemotherapy or palliative treatment, and OS were investigated. ADL patients with a Barthel index of >= 90 were classified as the high ADL group, while those with a score < 90 were classified as the low ADL group. For OS, patients surviving >= 160 days were classified as the non-poor prognosis group, and those who survived <160 days were classified as the poor prognosis group. Results: Age, sex, ADL, pain, the primary site, and treatment strategy for OS were different between the two groups (p < 0.1). Logistic regression analysis revealed that ADL, the primary site, and treatment strategy were significant predictors of OS (p < 0.05). High ADL, breast cancer, and chemotherapy had a positive effect on OS. Conclusions: It is suggested that improvements may be obtained by performing rehabilitation interventions to maintain and improve ADL, by constructing a system for monitoring spinal bone metastases with images before ADL decreases, and by performing interventions such as changes in treatment methods such as RT or surgery at appropriate times. en-copyright= kn-copyright= en-aut-name=AkezakiYoshiteru en-aut-sei=Akezaki en-aut-mei=Yoshiteru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KikuuchiMasato en-aut-sei=Kikuuchi en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SugiharaShinsuke en-aut-sei=Sugihara en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatayamaYoshimi en-aut-sei=Katayama en-aut-mei=Yoshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatayamaHaruyoshi en-aut-sei=Katayama en-aut-mei=Haruyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HamadaMasanori en-aut-sei=Hamada en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Division of Physical Therapy, Kochi Professional University of Rehabilitation kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Rehabilitation Medicine, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=4 en-affil=Department of Rehabilitation Medicine, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=5 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= en-keyword=spinal bone metastases kn-keyword=spinal bone metastases en-keyword=radiotherapy kn-keyword=radiotherapy en-keyword=chemotherapy kn-keyword=chemotherapy en-keyword=activities of daily living kn-keyword=activities of daily living en-keyword=overall survival kn-keyword=overall survival END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=4 article-no= start-page=e1010732 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230428 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Overexpression profiling reveals cellular requirements in the context of genetic backgrounds and environments en-subtitle= kn-subtitle= en-abstract= kn-abstract=Overexpression can help life adapt to stressful environments, making an examination of overexpressed genes valuable for understanding stress tolerance mechanisms. However, a systematic study of genes whose overexpression is functionally adaptive (GOFAs) under stress has yet to be conducted. We developed a new overexpression profiling method and systematically identified GOFAs in Saccharomyces cerevisiae under stress (heat, salt, and oxidative). Our results show that adaptive overexpression compensates for deficiencies and increases fitness under stress, like calcium under salt stress. We also investigated the impact of different genetic backgrounds on GOFAs, which varied among three S. cerevisiae strains reflecting differing calcium and potassium requirements for salt stress tolerance. Our study of a knockout collection also suggested that calcium prevents mitochondrial outbursts under salt stress. Mitochondria-enhancing GOFAs were only adaptive when adequate calcium was available and non-adaptive when calcium was deficient, supporting this idea. Our findings indicate that adaptive overexpression meets the cell's needs for maximizing the organism's adaptive capacity in the given environment and genetic context. Author summaryThe study aimed to investigate how overexpression of genes can aid organisms in adapting to stress. The researchers utilized a new method to identify genes in yeast that demonstrated functional adaptability when overexpressed under stress such as heat, salt, and oxidative stress. The results indicated that overexpressing specific genes, like calcium, during salt stress could counteract deficiencies and improve the organism's ability to withstand stress. The study also examined the effect of different genetic backgrounds on these genes and discovered that the impact differed among various yeast strains. Additionally, the study revealed that calcium could play a key role in adapting to salt stress by preventing mitochondrial outbursts. These findings suggest that overexpressing certain genes can help the organism maximize its adaptability to stress in a given environment and genetic context. en-copyright= kn-copyright= en-aut-name=SaekiNozomu en-aut-sei=Saeki en-aut-mei=Nozomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoChie en-aut-sei=Yamamoto en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EguchiYuichi en-aut-sei=Eguchi en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SekitoTakayuki en-aut-sei=Sekito en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShigenobuShuji en-aut-sei=Shigenobu en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshimuraMami en-aut-sei=Yoshimura en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YashirodaYoko en-aut-sei=Yashiroda en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=BooneCharles en-aut-sei=Boone en-aut-mei=Charles kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoriyaHisao en-aut-sei=Moriya en-aut-mei=Hisao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=Biomedical Business Center, RICOH Futures BU kn-affil= affil-num=4 en-affil=Graduate School of Agriculture, Ehime University kn-affil= affil-num=5 en-affil=National Institute for Basic Biology kn-affil= affil-num=6 en-affil=RIKEN Center for Sustainable Resource Science kn-affil= affil-num=7 en-affil=RIKEN Center for Sustainable Resource Science kn-affil= affil-num=8 en-affil=RIKEN Center for Sustainable Resource Science kn-affil= affil-num=9 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=4 article-no= start-page=364 end-page=376 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between High Pericoronary Adipose Tissue Computed Tomography Attenuation and Impaired Flow-Mediated Dilation of the Brachial Artery en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims: Pericoronary adipose tissue (PCAT) attenuation on coronary computed tomography angiography (CTA) is a noninvasive biomarker for pericoronary inflammation and is associated with cardiac mortality. We aimed to investigate the association between PCAT attenuation and endothelial dysfunction assessed using flow-mediated dilation (FMD).
Methods: A total of 119 outpatients who underwent both coronary CTA and FMD measurements were examined. PCAT attenuation values were assessed at the proximal 40-mm segments of all three major coronary arteries on coronary CTA. Endothelial function was assessed using FMD. Patients were then classified into two groups: those with endothelial dysfunction (FMD ＜4%, n=44) and those without endothelial dysfunction (FMD ≥ 4%, n=75).
Results: In all three coronary arteries, PCAT attenuation was significantly higher in patients with endothelial dysfunction than in those without endothelial dysfunction. Multivariate logistic regression analysis revealed that PCAT attenuation in the right coronary artery (odds ratio [OR]=1.543; 95% confidence interval [CI]=1.004–2.369, p=0.048) and left anterior descending artery (OR=1.525, 95% CI=1.004–2.369, p=0.049) was an independent predictor of endothelial dysfunction. Subgroup analysis of patients with adverse CTA findings (significant stenosis and/or high-risk plaque) and those with coronary artery calcium score ＞100 showed that high PCAT attenuation in all three coronary arteries was a significant predictor of endothelial dysfunction.
Conclusion: High PCAT attenuation was significantly associated with FMD-assessed endothelial dysfunction in patients with suspected coronary artery disease. Our results suggest that endothelial dysfunction is one of the pathophysiological mechanisms linking pericoronary inflammation to cardiac mortality. en-copyright= kn-copyright= en-aut-name=IchikawaKeishi en-aut-sei=Ichikawa en-aut-mei=Keishi 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=OhnoYuko en-aut-sei=Ohno en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OsawaKazuhiro en-aut-sei=Osawa en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakashimaMitsutaka en-aut-sei=Nakashima en-aut-mei=Mitsutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishiharaTakahiro en-aut-sei=Nishihara en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MikiTakashi en-aut-sei=Miki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TodaHironobu en-aut-sei=Toda en-aut-mei=Hironobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YoshidaMasatoki en-aut-sei=Yoshida en-aut-mei=Masatoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Cardiovascular 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 Medical technology, Kawasaki University of Medical Welfare kn-affil= affil-num=4 en-affil=Department of General Internal Medicine 3, Kawasaki Medical School General Medicine Center 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= affil-num=10 en-affil=Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Coronary computed tomography angiography kn-keyword=Coronary computed tomography angiography en-keyword=Perivascular coronary inflammation kn-keyword=Perivascular coronary inflammation en-keyword=Endothelial dysfunction kn-keyword=Endothelial dysfunction en-keyword=Flow-mediated dilation kn-keyword=Flow-mediated dilation END start-ver=1.4 cd-journal=joma no-vol=447 cd-vols= no-issue= article-no= start-page=120608 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230415 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Neuroprotective effects of carnosine in a mice stroke model concerning oxidative stress and inflammatory response en-subtitle= kn-subtitle= en-abstract= kn-abstract=Carnosine (β-alanyl-L-histidine) is a natural dipeptide with multiple neuroprotective properties. Previous studies have advertised that carnosine scavenges free radicals and displays anti-inflammatory activity. However, the underlying mechanism and the efficacies of its pleiotropic effect on prevention remained obscure. In this study, we aimed to investigate the anti-oxidative, anti-inflammative, and anti-pyroptotic effects of carnosine in the transient middle cerebral artery occlusion (tMCAO) mouse model. After a daily pre-treatment of saline or carnosine (1000 mg / kg / day) for 14 days, mice (n = 24) were subjected to tMCAO for 60 min and continuously treated with saline or carnosine for additional 1 and 5 days after reperfusion. The administration of carnosine significantly decreased infarct volume 5 days after the tMCAO (*p < 0.05) and effectively suppressed the expression of 4-HNE, 8-OHdG, Nitrotyrosine 5 days, and RAGE 5 days after tMCAO. Moreover, the expression of IL-1β was also significantly suppressed 5 days after tMCAO. Our present findings demonstrated that carnosine effectively relieves oxidative stress caused by ischemic stroke and significantly attenuates neuroinflammatory responses related to IL-1β, suggesting that carnosine can be a promising therapeutic strategy for ischemic stroke. en-copyright= kn-copyright= en-aut-name=HuXinran en-aut-sei=Hu en-aut-mei=Xinran kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukuiYusuke en-aut-sei=Fukui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FengTian en-aut-sei=Feng en-aut-mei=Tian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BianZhihong en-aut-sei=Bian en-aut-mei=Zhihong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YuHaibo en-aut-sei=Yu en-aut-mei=Haibo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MoriharaRyuta en-aut-sei=Morihara en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HuXiao en-aut-sei=Hu en-aut-mei=Xiao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=BianYuting en-aut-sei=Bian en-aut-mei=Yuting kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SunHongming en-aut-sei=Sun en-aut-mei=Hongming kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakemotoMami en-aut-sei=Takemoto en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NakanoYumiko en-aut-sei=Nakano en-aut-mei=Yumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YunokiTaijun en-aut-sei=Yunoki en-aut-mei=Taijun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=AbeKoji en-aut-sei=Abe en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=YamashitaToru en-aut-sei=Yamashita en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=13 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=14 en-affil=Department of Neurology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Ischemic stroke kn-keyword=Ischemic stroke en-keyword=Carnosine kn-keyword=Carnosine en-keyword=Middle cerebral artery occlusion kn-keyword=Middle cerebral artery occlusion en-keyword=Oxidative stress kn-keyword=Oxidative stress en-keyword=Inflammation kn-keyword=Inflammation en-keyword=Pyroptosis kn-keyword=Pyroptosis END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=2 article-no= start-page=215 end-page=220 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202304 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Three Cases of Down Syndrome with Transient Abnormal Myelopoiesis who Underwent Liver Biopsy before Induction of Low-Dose Cytarabine en-subtitle= kn-subtitle= en-abstract= kn-abstract=Among patients with transient abnormal myelopoiesis (TAM) associated with Down syndrome, approximately 20% die within 6 months from multiorgan failure, especially liver fibrosis.

To secure circumferential resection margin by tumor reduction, he received chemoradiotherapy as total neoadjuvant therapy (TNT) and underwent laparoscopic abdominoperineal resection, D3 lymph node dissection, combined coccyx resection, and partial resection of the right GM muscle. The skin defect and pelvic dead space were filled with a right lateral vastus lateral great muscle flap. Histopathologically, the resected specimen showed no tumor cells in the primary tumor or lymph nodes, indicating a pathological complete response (pCR). This case suggests that TNT might improve the R0 resection and pCR rates and overall survival. en-copyright= kn-copyright= en-aut-name=SakamotoMasaki en-aut-sei=Sakamoto en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=ShigeyasuKunitoshi kn-aut-sei=Shigeyasu kn-aut-mei=Kunitoshi aut-affil-num=3 ORCID= en-aut-name=KagawaShunsuke en-aut-sei=Kagawa en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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= en-keyword=locally advanced rectal cancer kn-keyword=locally advanced rectal cancer en-keyword=total neoadjuvant therapy kn-keyword=total neoadjuvant therapy en-keyword=lateral vastus lateral great muscle flap kn-keyword=lateral vastus lateral great muscle flap END start-ver=1.4 cd-journal=joma no-vol=63 cd-vols= no-issue=1 article-no= start-page=25 end-page=31 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=Comparison of serum sIL-2R and LDH levels in patients with intravascular large B-cell lymphoma and patients with advanced stage diffuse large B-cell lymphoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Intravascular large B-cell lymphoma (IVL) is a rare type of lymphoma characterized by tumor growth selectively within the vessels. The 5th edition of the World Health Organization classification defines IVL as a large B-cell lymphoma, the same as diffuse large B-cell lymphoma, not otherwise specified (DLBCL, NOS). Since the clinical manifestations of IVL are nonspecific, the diagnosis is time-consuming, and the course is often fatal. Serum soluble interleukin-2 receptor (sIL-2R) and serum lactate dehydrogenase (LDH) levels are known to be elevated in a variety of lymphomas. However, the mechanism of sIL-2R elevation in B-cell lymphomas is not fully understood. In this study, we analyzed the serum level of laboratory findings, including sIL-2R and LDH, as well as the presence of B symptoms in 39 patients with IVL, and compared them with 56 patients with stage IV DLBCL. Both sIL-2R and LDH levels were significantly higher in IVL than in DLBCL (p = 0.035 andp = 0.002, respectively). In IVL, there were no significant differences in both sIL-2R and LDH levels between patients with and without B symptoms (p = 0.206 andp = 0.441, respectively). However, in DLBCL, both sIL-2R and LDH levels were significantly higher in the presence of B symptoms (p = 0.001 andp < 0.001, respectively). The high sIL-2R and LDH levels in IVL may be related to the peripheral blood microenvironment, but further studies are needed to verify this. en-copyright= kn-copyright= en-aut-name=HiramiYuki en-aut-sei=Hirami en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimuraMidori Filiz en-aut-sei=Nishimura en-aut-mei=Midori Filiz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UrataTomohiro en-aut-sei=Urata en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MorimotoMichiko en-aut-sei=Morimoto en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaekawaYukina en-aut-sei=Maekawa en-aut-mei=Yukina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshinoTadashi en-aut-sei=Yoshino en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Department of Nursing, Okayama University Graduate School of Health Sciences kn-affil= affil-num=2 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Nursing, Okayama University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=6 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= en-keyword=intravascular large B-cell lymphoma kn-keyword=intravascular large B-cell lymphoma en-keyword=diffuse large B-cell lymphoma kn-keyword=diffuse large B-cell lymphoma en-keyword=soluble interleukin-2 receptor kn-keyword=soluble interleukin-2 receptor en-keyword=lactate dehy-drogenase kn-keyword=lactate dehy-drogenase en-keyword=B symptoms kn-keyword=B symptoms END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue= article-no= start-page=e84291 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Chloride ions evoke taste sensations by binding to the extracellular ligand-binding domain of sweet/umami taste receptors en-subtitle= kn-subtitle= en-abstract= kn-abstract=Salt taste sensation is multifaceted: NaCl at low or high concentrations is preferably or aversively perceived through distinct pathways. Cl- is thought to participate in taste sensation through an unknown mechanism. Here, we describe Cl- ion binding and the response of taste receptor type 1 (T1r), a receptor family composing sweet/umami receptors. The T1r2a/T1r3 heterodimer from the medaka fish, currently the sole T1r amenable to structural analyses, exhibited a specific Cl- binding in the vicinity of the amino-acid-binding site in the ligand-binding domain (LBD) of T1r3, which is likely conserved across species, including human T1r3. The Cl- binding induced a conformational change in T1r2a/T1r3LBD at sub- to low-mM concentrations, similar to canonical taste substances. Furthermore, oral Cl- application to mice increased impulse frequencies of taste nerves connected to T1r-expressing taste cells and promoted their behavioral preferences attenuated by a T1r-specific blocker or T1r3 knock-out. These results suggest that the Cl- evokes taste sensations by binding to T1r, thereby serving as another preferred salt taste pathway at a low concentration. en-copyright= kn-copyright= en-aut-name=AtsumiNanako en-aut-sei=Atsumi en-aut-mei=Nanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YasumatsuKeiko en-aut-sei=Yasumatsu en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakashinaYuriko en-aut-sei=Takashina en-aut-mei=Yuriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ItoChiaki en-aut-sei=Ito en-aut-mei=Chiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=MargolskeeRobert F. en-aut-sei=Margolskee en-aut-mei=Robert F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=School of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Monell Chemical Senses Center kn-affil= affil-num=7 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=taste receptor kn-keyword=taste receptor en-keyword=salt taste kn-keyword=salt taste en-keyword=chloride kn-keyword=chloride en-keyword=O kn-keyword=O en-keyword=latipes kn-keyword=latipes en-keyword=Mouse kn-keyword=Mouse en-keyword=Other kn-keyword=Other 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=202303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Study of Sustainable Management in Arts and Cultural Activities en-subtitle= kn-subtitle= en-abstract= kn-abstract=Regional development is an urgent issue in Japan, which is facing various challenges including a declining population, an aging society, and the concentration of the population in Tokyo. Artistic and cultural activities are expected to play a role in community revitalization as cultural capital unique to the community. However, art museums and festivals face the problem of being unable to cover their operating expenses with revenue from their enterprise, and support from non-beneficiaries is necessary for sustainable operations, which is a prerequisite for community revitalization. This paper discusses the management issues of arts and cultural activities, particularly museums and art festivals, from a community revitalization perspective. As the number of stakeholders in arts and cultural activities expands, management must take on the role of organically linking the cultural capital of museums and art festivals with education, welfare, tourism, and industry. en-copyright= kn-copyright= en-aut-name=NishitaYosuke en-aut-sei=Nishita en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil= 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=12 cd-vols= no-issue=3 article-no= start-page=454 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230131 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Pursuit of the "Inside" of the Amyloid Hypothesis-Is C99 a Promising Therapeutic Target for Alzheimer's Disease? en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aducanumab, co-developed by Eisai (Japan) and Biogen (U.S.), has received Food and Drug Administration approval for treating Alzheimer's disease (AD). In addition, its successor antibody, lecanemab, has been approved. These antibodies target the aggregated form of the small peptide, amyloid-beta (A beta), which accumulates in the patient brain. The "amyloid hypothesis " based therapy that places the aggregation and toxicity of A beta at the center of the etiology is about to be realized. However, the effects of immunotherapy are still limited, suggesting the need to reconsider this hypothesis. A beta is produced from a type-I transmembrane protein, A beta precursor protein (APP). One of the APP metabolites, the 99-amino acids C-terminal fragment (C99, also called beta CTF), is a direct precursor of A beta and accumulates in the AD patient's brain to demonstrate toxicity independent of A beta. Conventional drug discovery strategies have focused on A beta toxicity on the "outside " of the neuron, but C99 accumulation might explain the toxicity on the "inside " of the neuron, which was overlooked in the hypothesis. Furthermore, the common region of C99 and A beta is a promising target for multifunctional AD drugs. This review aimed to outline the nature, metabolism, and impact of C99 on AD pathogenesis and discuss whether it could be a therapeutic target complementing the amyloid hypothesis. en-copyright= kn-copyright= en-aut-name=TakasugiNobumasa en-aut-sei=Takasugi en-aut-mei=Nobumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KomaiMasato en-aut-sei=Komai en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KaneshiroNanaka en-aut-sei=Kaneshiro en-aut-mei=Nanaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IkedaAtsuya en-aut-sei=Ikeda en-aut-mei=Atsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KamikuboYuji en-aut-sei=Kamikubo en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=Division of Biomedical Sciences, School of Medicine, University of California 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 Cellular and Molecular Pharmacology, Juntendo University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Alzheimer's disease kn-keyword=Alzheimer's disease en-keyword=amyloid-beta kn-keyword=amyloid-beta en-keyword=amyloid beta precursor protein kn-keyword=amyloid beta precursor protein en-keyword=BACE1 kn-keyword=BACE1 en-keyword=C99 kn-keyword=C99 en-keyword=endolysosome kn-keyword=endolysosome en-keyword=autolysosome kn-keyword=autolysosome en-keyword=vesicular trafficking kn-keyword=vesicular trafficking END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=1 article-no= start-page=21 end-page=27 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=Analysis of Phase Angle and Balance and Gait Functions in Pre-Frail Individuals: A Cross-Sectional Observational Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=We measured the muscle mass and phase angle of each body part to evaluate the relationship between balance and gait functions in individuals with a pre-frailty status. This cross-sectional observational study determined the skeletal muscle mass-to-body weight ratio and phase angles of 21 control (robust) and 29 pre-frail subjects. Their Brief-Balance Evaluation Systems Test, Timed Up-and-Go (TUG) test, Life-Space Assessment, and Modified Fall Efficacy Scale scores plus the relationship between muscle mass, phase angle, and motor function were evaluated. In the pre-frailty group (three males, 26 females, aged 75.58±7.60 years), significant correlations were noted between the Brief-Balance Evaluation Systems Test score and lower-limb (r=0.614) and wholebody (r=0.557) phase angles, and between the TUG test score and lower-limb muscle mass-to-body weight ratio (r=−0.616), lower-limb phase angle (r=−0.616), and whole-body phase angle (r=−0.527). Evaluating the phase angle of the lower extremities of pre-frail patients and intervening accordingly may help clinicians maintain and improve these patients’ balance and gait functions. en-copyright= kn-copyright= en-aut-name=HommaDaisuke en-aut-sei=Homma en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MinatoIzumi en-aut-sei=Minato en-aut-mei=Izumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ImaiNorio en-aut-sei=Imai en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyasakaDai en-aut-sei=Miyasaka en-aut-mei=Dai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakaiYoshinori en-aut-sei=Sakai en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HorigomeYoji en-aut-sei=Horigome en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuzukiHayato en-aut-sei=Suzuki en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=DohmaeYoichiro en-aut-sei=Dohmae en-aut-mei=Yoichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=EndoNaoto en-aut-sei=Endo en-aut-mei=Naoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Orthopaedic Surgery, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=2 en-affil=Division of Orthopaedic Surgery, Niigata Rinko Hospital kn-affil= affil-num=3 en-affil=Comprehensive Musculoskeletal Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=4 en-affil=Division of Orthopaedic Surgery, Niigata Bandai Hospital kn-affil= affil-num=5 en-affil=Division of Orthopaedic Surgery, Niigata City General Hospital kn-affil= affil-num=6 en-affil=Comprehensive Musculoskeletal Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=7 en-affil=Orthopaedic Surgery, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=8 en-affil=Division of Orthopaedic Surgery, Niigata Bandai Hospital kn-affil= affil-num=9 en-affil=Division of Orthopaedic Surgery, Niigata Prefectural Tsubame Rosai Hospital kn-affil= en-keyword=bioelectrical impedance analysis kn-keyword=bioelectrical impedance analysis en-keyword=motor function kn-keyword=motor function en-keyword=muscle quality kn-keyword=muscle quality en-keyword=muscle volume kn-keyword=muscle volume END start-ver=1.4 cd-journal=joma no-vol=112 cd-vols= no-issue= article-no= start-page=19 end-page=22 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=Sexual Dimorphism of Arginine Vasotocin Neuron in Birds kn-title=鳥類におけるアルギニンバソトシン神経の性差 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Arginine vasotocin (AVT) is one of neurohypophysial peptides in birds and is well known both as an antidiuretic and oxytocic hormone. AVT is produced in the hypothalamus and mainly synthesized in magnocellular neurons, supraoptic nucleus (SON) and paraventricular nucleus (PVN). Recent, immunocytochemistry and in situ hybridization results indicate that AVT is also synthesized in parvocellular neurons corresponding to mammalian stria terminalis (nST). The AVT neurons in nST in the male are more numerous than those in the female. Therefore, these data suggest that there is sexual dimorphism in the distribution of AVT neurons. Several experiments involving electrical lesion, testosterone implantation, and the detection of the immediately-early gene expression in birds expressing copulatory behavior suggested that nST and nucleus praeopticus medialis (POM) were related to the reproductive behavior. When male embryo was treated with estradiol, the distribution of AVT neurons assumes the same distribution as found in the female, and reproductive behavior was abolished, suggesting that AVT in the brain has an important role in reproductive behavior. en-copyright= kn-copyright= en-aut-name=SaitoNoboru en-aut-sei=Saito en-aut-mei=Noboru kn-aut-name=齋藤昇 kn-aut-sei=齋藤 kn-aut-mei=昇 aut-affil-num=1 ORCID= affil-num=1 en-affil=Course of Applied Animal Science kn-affil=応用動物科学コース en-keyword=arginine vasotocin kn-keyword=arginine vasotocin en-keyword=sexual dimorphism kn-keyword=sexual dimorphism en-keyword=reproductive behavior kn-keyword=reproductive behavior en-keyword=parvocellular neurons kn-keyword=parvocellular neurons en-keyword=bird kn-keyword=bird END start-ver=1.4 cd-journal=joma no-vol=298 cd-vols= no-issue=12 article-no= start-page=102668 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Crystal structures of photosystem II from a cyanobacterium expressing psbA2 in comparison to psbA3 reveal differences in the D1 subunit en-subtitle= kn-subtitle= en-abstract= kn-abstract=Three psbA genes (psbA1, psbA2, and psbA3) encoding the D1 subunit of photosystem II (PSII) are present in the ther-mophilic cyanobacterium Thermosynechococcus elongatus and are expressed differently in response to changes in the growth environment. To clarify the functional differences of the D1 protein expressed from these psbA genes, PSII dimers from two strains, each expressing only one psbA gene (psbA2 or psbA3), were crystallized, and we analyzed their structures at resolu-tions comparable to previously studied PsbA1-PSII. Our results showed that the hydrogen bond between pheophytin/D1 (PheoD1) and D1-130 became stronger in PsbA2-and PsbA3-PSII due to change of Gln to Glu, which partially explains the increase in the redox potential of PheoD1 observed in PsbA3. In PsbA2, one hydrogen bond was lost in PheoD1 due to the change of D1-Y147F, which may explain the decrease in stability of PheoD1 in PsbA2. Two water molecules in the Cl-1 channel were lost in PsbA2 due to the change of D1-P173M, leading to the narrowing of the channel, which may explain the lower efficiency of the S-state transition beyond S2 in PsbA2-PSII. In PsbA3-PSII, a hydrogen bond between D1-Ser270 and a sulfoquinovosyl-diacylglycerol molecule near QB dis-appeared due to the change of D1-Ser270 in PsbA1 and PsbA2 to D1-Ala270. This may result in an easier exchange of bound QB with free plastoquinone, hence an enhancement of oxygen evolution in PsbA3-PSII due to its high QB exchange efficiency. These results provide a structural basis for further functional examination of the three PsbA variants. en-copyright= kn-copyright= en-aut-name=NakajimaYoshiki en-aut-sei=Nakajima en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Ugai-AmoNatsumi en-aut-sei=Ugai-Amo en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ToneNaoki en-aut-sei=Tone en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakagawaAkiko en-aut-sei=Nakagawa en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwaiMasako en-aut-sei=Iwai en-aut-mei=Masako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IkeuchiMasahiko en-aut-sei=Ikeuchi en-aut-mei=Masahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SugiuraMiwa en-aut-sei=Sugiura en-aut-mei=Miwa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugaMichihiro en-aut-sei=Suga en-aut-mei=Michihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=Jian-RenShen en-aut-sei=Jian-Ren en-aut-mei=Shen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, 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=Proteo-Science Research Center, Ehime University kn-affil= affil-num=5 en-affil=Graduate School and College of Arts and Sciences, The University of Tokyo kn-affil= affil-num=6 en-affil=Graduate School and College of Arts and Sciences, The University of Tokyo kn-affil= affil-num=7 en-affil=Proteo-Science Research Center, Ehime University kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=9 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=12 article-no= start-page=1032 end-page=1039 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221121 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of number of functional teeth on independence of Japanese older adults en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim
To examine the relationship between the number of present and functional teeth at baseline and future incidence of loss of independence.

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

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

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

dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical implications and optimal extent of lymphadenectomy for intrahepatic cholangiocarcinoma: A multicenter analysis of the therapeutic index en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims Lymph node metastases (LNM) are associated with lethal prognosis in intrahepatic cholangiocarcinoma (ICC). Lymphadenectomy is crucial for accurate staging and hopes of possible oncological treatment. However, the therapeutic implications and optimal extent of lymphadenectomy remain contentious. Methods To clarify the prognostic value and optimal extent of lymphadenectomy, the therapeutic index (TI) for each lymph node was analyzed for 279 cases that had undergone lymphadenectomy in a multi-institutional database. Tumor localization was divided into hilar lesions (n = 130), right peripheral lesions (n = 60), and left peripheral lesions (n = 89). In addition, the lymph node station was classified as Level 1 (LV1: hepatoduodenal ligament node), Level 2 (LV2: postpancreatic or common hepatic artery nodes), or Level 3 (LV3: gastrocardiac, left gastric artery, or celiac artery nodes). Results Lymph node metastases were confirmed in 109 patients (39%). Five-y survival rates were 45.3% for N0 disease, 27.1% for LV1-LNM, 22.9% for LV2-LNM, and 7.3% for LV3-LNM (P < 0.001). LV3-LNM were the most frequent and earliest recurrence outcome, including multisite recurrence, followed by LV2, LV1, and N0 disease. The 5-year TI (5year-TI) for lymphadenectomy was 7.2 for LV1, 5.5 for LV2, and 1.9 for LV3. Regarding tumor location, hilar lesions showed 5-year TI > 5.0 in LV1 and LV2, whereas bilateral peripheral lesions showed 5-year TI > 5.0 in LV1. Conclusion The implications and extent of lymphadenectomy for ICC appear to rely on tumor location. In the peripheral type, the benefit of lymphadenectomy would be limited and dissection beyond LV1 should be avoided, while in the hilar type, lymphadenectomy up to LV2 could be recommended. en-copyright= kn-copyright= en-aut-name=UmedaYuzo en-aut-sei=Umeda en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsudaTatsuo en-aut-sei=Matsuda en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KojimaToru en-aut-sei=Kojima en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SatohDaisuke en-aut-sei=Satoh en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HiokiMasayoshi en-aut-sei=Hioki en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=EndoYoshikatsu en-aut-sei=Endo en-aut-mei=Yoshikatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=InagakiMasaru en-aut-sei=Inagaki en-aut-mei=Masaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OishiMasahiro en-aut-sei=Oishi en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YagiTakahito en-aut-sei=Yagi en-aut-mei=Takahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Surgery, Tenwakai Matsuda Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Surgery, Okayama Saiseikai General Hospital kn-affil= affil-num=6 en-affil=Department of Surgery, Hiroshima Citizens Hospital kn-affil= affil-num=7 en-affil=Department of Surgery, Fukuyama City Hospital kn-affil= affil-num=8 en-affil=Department of Surgery, Himeji Red Cross Hospital kn-affil= affil-num=9 en-affil=Department of Surgery, National Hospital Organization Fukuyama Medical Center kn-affil= affil-num=10 en-affil=Department of Surgery, Tottori Municipal Hospital kn-affil= affil-num=11 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=intrahepatic cholangiocarcinoma kn-keyword=intrahepatic cholangiocarcinoma en-keyword=lymphadenectomy kn-keyword=lymphadenectomy en-keyword=multicenter study kn-keyword=multicenter study en-keyword=retrospective study kn-keyword=retrospective study END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=23 article-no= start-page=15796 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Are Prophylactic Systemic Antibiotics Required in Patients with Cataract Surgery at Local Anesthesia? en-subtitle= kn-subtitle= en-abstract= kn-abstract=The reduced use of antimicrobial drugs has been recommended worldwide, according to the global action for antimicrobial resistance published in 2015 by the World Health Organization. In this study, we retrospectively reviewed the incidence of surgical site infection in consecutive patients with cataract surgeries at a single hospital in the 6-year process when prophylactic systemic antibiotics were reduced in a step-by-step manner. The entire study period from 2016 to 2022 was divided into five stages, based on the use of systemic antibiotics. In stage 1 with 649 cataract surgeries, an intravenous drip infusion of cefazolin 1 g was given at surgery, followed by oral cefdinir 100 mg in the evening on surgery day and three times for two postoperative days. In stage 2 with 541 cataract surgeries, oral cefdinir 100 mg was given in the late morning before surgery, in the evening, and three times (300 mg in total) for two postoperative days. In stage 3 with 103 cataract surgeries, oral levofloxacin 500 mg was given in the late morning before surgery and once in the morning for two postoperative days. In stage 4 with 545 cataract surgeries, oral levofloxacin 500 mg was given only in the late morning before surgery. In stage 5 with 311 cataract surgeries, no systemic antibiotics were given. As common procedures in all stages, moxifloxacin eye drops were given four times daily as topical antibiotics in the 3 days before surgery and about 2 weeks after surgery. At surgery, the ocular surface was frequently irrigated with saline-diluted povidone iodine at 0.5% working concentration. No postoperative infection was recorded in any stage. This study showed neither harm nor risk in reduced use and, consequently, no use of prophylactic systemic antibiotics in cataract surgery as far as local precautionary measures were secured. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IguchiMasahiro en-aut-sei=Iguchi en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorisatoNoriyasu en-aut-sei=Morisato en-aut-mei=Noriyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MurasakoTatsuya en-aut-sei=Murasako en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=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= Department of Pharmacy, Ochiai Hospital kn-affil= affil-num=3 en-affil= Department of Pharmacy, Ochiai Hospital kn-affil= affil-num=4 en-affil= Clinical Laboratories, Ochiai Hospital kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Hospital kn-affil= en-keyword=cataract surgery kn-keyword=cataract surgery en-keyword=global action plan kn-keyword=global action plan en-keyword=antimicrobial resistance kn-keyword=antimicrobial resistance en-keyword=appropriate use kn-keyword=appropriate use en-keyword=antibiotics kn-keyword=antibiotics en-keyword=oral kn-keyword=oral en-keyword=intravenous kn-keyword=intravenous en-keyword=topical kn-keyword=topical en-keyword=povidone iodine kn-keyword=povidone iodine en-keyword=conjunctival sac culture kn-keyword=conjunctival sac culture END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=1 article-no= start-page=e15275 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221018 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Late‐onset familial Diamond–Blackfan anemia with neutropenia caused by RPL35A variant en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=TamefusaKosuke en-aut-sei=Tamefusa en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MuraokaMichiko en-aut-sei=Muraoka en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WashioKana en-aut-sei=Washio en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WakamatsuManabu en-aut-sei=Wakamatsu en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShimadaAkira en-aut-sei=Shimada en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Pediatrics, Fukuyama City Hospital kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pediatrics, Nagoya University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= en-keyword=Diamond-Blackfan anemia kn-keyword=Diamond-Blackfan anemia en-keyword=neutropenia kn-keyword=neutropenia en-keyword=next-generation sequencing kn-keyword=next-generation sequencing en-keyword=RPL35A kn-keyword=RPL35A en-keyword=variant kn-keyword=variant END start-ver=1.4 cd-journal=joma no-vol=289 cd-vols= no-issue=1985 article-no= start-page=20221126 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221019 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Footedness for scratching itchy eyes in rodents en-subtitle= kn-subtitle= en-abstract= kn-abstract=The neural bases of itchy eye transmission remain unclear compared with those involved in body itch. Here, we show in rodents that the gastrin-releasing peptide receptor (GRPR) of the trigeminal sensory system is involved in the transmission of itchy eyes. Interestingly, we further demonstrate a difference in scratching behaviour between the left and right hindfeet in rodents; histamine instillation into the conjunctival sac of both eyes revealed right-foot biased laterality in the scratching movements. Unilateral histamine instillation specifically induced neural activation in the ipsilateral sensory pathway, with no significant difference between the activations following left- and right-eye instillations. Thus, the behavioural laterality is presumably due to right-foot preference in rodents. Genetically modified rats with specific depletion of Grpr-expressing neurons in the trigeminal sensory nucleus caudalis of the medulla oblongata exhibited fewer and shorter histamine-induced scratching movements than controls and eliminated the footedness. These results taken together indicate that the Grp-expressing neurons are required for the transmission of itch sensation from the eyes, but that foot preference is generated centrally. These findings could open up a new field of research on the mechanisms of the laterality in vertebrates and also offer new potential therapeutic approaches to refractory pruritic eye disorders. en-copyright= kn-copyright= en-aut-name=KatayamaYukitoshi en-aut-sei=Katayama en-aut-mei=Yukitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiuraAyane en-aut-sei=Miura en-aut-mei=Ayane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakamotoTatsuya en-aut-sei=Sakamoto en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakanamiKeiko en-aut-sei=Takanami en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakamotoHirotaka en-aut-sei=Sakamoto en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University, Ushimado, Setouchi kn-affil= affil-num=2 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University, Ushimado, Setouchi kn-affil= affil-num=3 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University, Ushimado, Setouchi kn-affil= affil-num=4 en-affil=Mouse Genomics Resources Laboratory, National Institute of Genetics, Yata, Mishima kn-affil= affil-num=5 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University, Ushimado, Setouchi kn-affil= en-keyword=itchy eyes kn-keyword=itchy eyes en-keyword=histamine kn-keyword=histamine en-keyword=gastrin-releasing peptide receptor kn-keyword=gastrin-releasing peptide receptor en-keyword=footedness kn-keyword=footedness 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=6 article-no= start-page=679 end-page=688 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=Efficacy and Safety of Three-dimensional Conformal Radiotherapy for Macroscopic Vascular Invasion of Hepatocellular Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chemotherapy is insufficient to treat macroscopic vascular invasion (MVI) of hepatocellular carcinoma (HCC). We retrospectively investigated the treatment outcomes of patients who underwent three-dimensional conformal radiotherapy (3D-CRT) for HCC MVI and analyzed prognostic factors by multivariate analysis using a Cox proportional hazard model. Sixty-five patients were studied. MVI sites were the portal vein (n=48 patients), portal and hepatic veins (n=8), and hepatic vein (n=9). The median irradiation dose was 50 Gy. The median survival time (MST) was 7.5 months. Performance status 2 or 3, modified albumin-bilirubin grade 2b or 3, and massive/diffuse type were poor prognostic factors. Nineteen patients (29%) with a treatment effect of 3 or 4 (≥ 50% of tumor necrosis or regression) at the irradiation sites according to the Response Evaluation Criteria in Cancer of the Liver showed longer survival than those with an effect of 1 or 2 (MST 18.7 vs. 5.9 months, p<0.001). No treatment-related death occurred. The hepatic function reserve was preserved in more than 70% of patients. 3D-CRT controlled HCC MVI safely and was suggested to be a good treatment option. en-copyright= kn-copyright=

en-subject= kn-subject= en-title= kn-title=Second extracellular protease mediating maturation of Vibrio mimicus hemolysin en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vibrio mimicus is a bacterium that causes gastroenteritis in humans. This pathogen produces an enterotoxic hemolysin called V. mimicus hemolysin (VMH), which is secreted extracellularly as an inactive 80-kDa protoxin and converted to a 66-kDa mature toxin through cleavage between Arg(151) and Ser(152). The 56-kDa serine protease termed V. mimicus trypsin-like protease (VmtA) is known to mediate this maturating process. However, some strains including strain ES-20 does not possess the vmtA gene. In the present study, the vmtA-negative strains were found to have a replaced gene that encodes a 43-kDa (403 aa) precursor of a serine protease designated by VmtX (V. mimicus trypsin-like protease X). To examine whether VmtX is also involved in the maturation of VMH, VmtX was isolated from the culture supernatant of V. mimicus strain NRE-20, a metalloprotease-negative mutant constructed from strain ES-20. Concretely, the culture supernatant was fractionated with 70% saturated ammonium sulfate and subjected to affinity column chromatography using a HiTrap Benzamidine FF column. The analysis of the N-terminal amino acid sequences of the proteins in the obtained VmtX preparation indicated that the 39-kDa protein was active VmtX consisting of 371 aa (Ile(33)-Ser(403)). The VmtX preparation was found to activate pro-VMH through generation of the 66-kDa protein. Additionally, treatment of the VmtX preparation with serine protease inhibitors, such as leupeptin and phenylmethylsulfonyl fluoride, significantly suppressed the activities to hydrolyze the specific peptide substrate and to synthesize the 66-kDa toxin. These findings indicate that VmtX is the second protease that mediats the maturation of VMH. en-copyright= kn-copyright= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TokoNorie en-aut-sei=Toko en-aut-mei=Norie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DodoTetsuya en-aut-sei=Dodo en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NankoAyako en-aut-sei=Nanko en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MizunoTamaki en-aut-sei=Mizuno en-aut-mei=Tamaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Vibrio mimicus kn-keyword=Vibrio mimicus en-keyword=Serine protease kn-keyword=Serine protease en-keyword=Hemolysin kn-keyword=Hemolysin en-keyword=Maturation kn-keyword=Maturation END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=4 article-no= start-page=267 end-page=284 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221018 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Traditional Chinese Medicines and Prescriptions Brought from China to Japan by a Monk (Jianzhen, Japanese: Ganjin): A Historical Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=(1) Background: Japanese Kampo medicine has its origin in ancient Chinese medicine. In 742, a Tang Dynasty monk named Jianzhen (Ganjin) was invited by Japanese clerics to visit Japan and teach commandments in Buddhism. Because of the dangers of the voyage and also other obstacles, he took 11 years to reach Japan on the sixth voyage and he was blind when he arrived in Japan. He was the first person in China to go to Japan to establish the Buddhism commandments, and he was also the first person in Japan to directly teach traditional Chinese medicine. Until now, there have been few reports in English about the details of the Chinese herbal medicines he brought to Japan, including the types of herbal medicines, pharmacological activities, and formulations. In the review, we systematically and comprehensively summarized Jianzhen’s life from the standpoint of his medical and pharmaceutical knowledge and the types and pharmacological activities of Chinese herbal medicines and prescriptions that were brought to Japan by Jianzhen;
(2) Methods: A review was made on the relevant literature written by Chinese, Japanese, and English languages regarding the medical and pharmacological knowledge of Jianzhen, the 36 Chinese herbal medicines brought to Japan by Jianzhen, and the pharmacological and therapeutic effects of these 36 herbal medicines, as well as their formulations;
(3) Results: The review of the literature proved that Jianzhen’s prescriptions served as a basis for current herbal medicines (Kampo) in Japan. In the process of the literature search, we found a book entitled Jianshangren (Holy Priest Jianzhen)’s Secret Prescription, which recorded the complete prescription of the 36 traditional Chinese medicines Jianzhen brought to Japan;
(4) Conclusions: Jianzhen is one of the ancestors of traditional Chinese medicine/Kampo medicine, and he brought traditional Chinese medicine and medical books to Japan for patients. He made important contributions to the development of traditional Chinese medicine in Japan. en-copyright= kn-copyright= en-aut-name=LiuShihui en-aut-sei=Liu en-aut-mei=Shihui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuoChie en-aut-sei=Matsuo en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AbeTakumi en-aut-sei=Abe en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Jianzhen kn-keyword=Jianzhen en-keyword=Ganjin kn-keyword=Ganjin en-keyword=traditional Chinese medicine kn-keyword=traditional Chinese medicine en-keyword=Kampo medicine kn-keyword=Kampo medicine en-keyword=herbal medicine kn-keyword=herbal medicine en-keyword=medical history kn-keyword=medical history en-keyword=Toshodaiji Temple kn-keyword=Toshodaiji Temple en-keyword=traditional Japanese medicine kn-keyword=traditional Japanese medicine en-keyword=Nara kn-keyword=Nara en-keyword=Tang Dynasty kn-keyword=Tang Dynasty END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=2 article-no= start-page=1110 end-page=1118 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Patient-Participation Continuous Nutritional Counseling in Gastric Cancer Patients who Underwent Gastrectomy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background. Body weight loss (BWL) and skeletal muscle loss (SML) are inevitable after gastrectomy for gastric cancer (GC) and can decrease patients’ quality of life (QOL) and survival.
Objective. The aim of this retrospective study was to evaluate the effect of perioperative and post-discharge patient participation in continuous nutritional counseling (CNC) on post-gastrectomy BWL and SML.
Methods. Ninety-three patients with GC who underwent curative gastrectomy between March 2018 and July 2019 were analyzed. Patients received either pre-discharge nutritional counseling alone (control group, n = 49) or patient-participation CNC (CNC group, n = 44) after gastrectomy. Differences between percentage BWL (%BWL), percentage SML (%SML), and nutrition-related blood parameters between the preoperative values and those at 12 months after surgery were compared between the groups.
Results. Compared with the control group, %BWL was significantly lower in the CNC group at 1 month (−6.2 ± 2.5% vs. −7.9 ± 3.3%, p = 0.005), 6 months (−7.8 ± 6.6% vs. −12.3 ± 6.4%, p = 0.001) and 12 months (−7.9 ± 7.6% vs. −13.2 ± 8.2%, p = 0.002), and %SML was significantly lower in the CNC group at 12 months (−5.3 ± 10.3% vs. −12.8 ± 12%, p = 0.002). Regarding nutrition-related blood parameters, change in total cholesterol was significantly lower in the CNC group than the control group at 12 months after surgery (p = 0.02). Multivariate analysis identified no CNC as an independent risk factor for severe BWL (p = 0.001) and SML (p = 0.006) at 12 months after surgery.
Conclusions. Following gastrectomy, patient-participation CNC prevented postoperative BWL and SML after surgery. These results support the induction of such a CNC program in these patients. en-copyright= kn-copyright= en-aut-name=TakataNobuo en-aut-sei=Takata en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KikuchiSatoru en-aut-sei=Kikuchi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurodaShinji en-aut-sei=Kuroda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=MaedaNaoaki en-aut-sei=Maeda en-aut-mei=Naoaki 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=TakahashiAyako en-aut-sei=Takahashi en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=ShikataKenichi en-aut-sei=Shikata en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=11 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine, kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine 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 Clinical Nutrition, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Clinical Nutrition, Okayama University Hospital, Okayama, Japan Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=11 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Gastric cancer kn-keyword=Gastric cancer en-keyword=Gastrectomy kn-keyword=Gastrectomy en-keyword=Body weight loss kn-keyword=Body weight loss en-keyword=Skeletal muscle loss kn-keyword=Skeletal muscle loss en-keyword=Nutritional counseling kn-keyword=Nutritional counseling END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=792 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221011 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prevalence of medical factors related to aging among older car drivers: a multicenter, cross-sectional, descriptive study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim An increasing number of older adults in Japan are at an increased risk of road traffic crashes. This study aimed to investigate the prevalence of potential underlying medical factors that increase the risk of road traffic crashes among older people. Methods This cross-sectional observational study was conducted in 11 medical institutions in Japan using self-administered questionnaires and physical examination from January to May 2021. The background and social data, data on the use of nursing care insurance, and clinical data suggestive of polypharmacy, sarcopenia, cognitive impairment, and frailty/oral frailty were obtained. The prevalence of these factors was compared between everyday and occasional drivers. Results Data of 127 patients were collected; their median (interquartile range) age was 73 (70-78) years. Of the total participants, 82 were men (64.6%) and 45 were women (35.4%). There were 77 everyday drivers and 50 occasional drivers. Of these, 121 (95.3%) had not applied for nursing care insurance, but the numbers of those who required help 1 and 2 were 1 (0.8%) and 3 (2.4%), respectively. Prevalence of medical factors was as follows: polypharmacy, 27.6%; sarcopenia, 8.7%; dementia, 16.4%; frailty, 15.0%; and oral frailty, 54.3%; it was not significantly different between every day and occasional drivers. Intention to return the car license was significantly higher among the occasional drivers (2.6% vs. 14.0%; odds ratio: 6.7, 95% confidence interval: 1.2-70.6, p = 0.024). Conclusion We uncovered the prevalence of medical factors that can be associated with road traffic crashes among Japanese older people aged >= 65 years in our community. en-copyright= kn-copyright= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakaseRyosuke en-aut-sei=Takase en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 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=5 ORCID= en-aut-name=KataokaHitomi en-aut-sei=Kataoka en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UnoMika en-aut-sei=Uno en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UedaKeigo en-aut-sei=Ueda en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakahashiMisa en-aut-sei=Takahashi en-aut-mei=Misa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OgawaHiroko en-aut-sei=Ogawa en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HanayamaYoshihisa en-aut-sei=Hanayama en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of General Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of General Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of General Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of General Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of General Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of General Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of General Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of General Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Department of General Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of General Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=12 en-affil=Department of General Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Traffic safety kn-keyword=Traffic safety en-keyword=Older people kn-keyword=Older people en-keyword=Aging kn-keyword=Aging en-keyword=Motor vehicle accidents kn-keyword=Motor vehicle accidents en-keyword=Frailty kn-keyword=Frailty en-keyword=Dementia kn-keyword=Dementia en-keyword=Polypharmacy kn-keyword=Polypharmacy en-keyword=Sarcopenia kn-keyword=Sarcopenia 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=76 cd-vols= no-issue=4 article-no= start-page=473 end-page=477 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genomic Profiling of a Case of Glioneuronal Tumor with Neuropil-like Islands en-subtitle= kn-subtitle= en-abstract= kn-abstract=Glioneuronal tumor with neuropil-like islands (GNTNI) is a very rare subtype of glioneuronal tumor. We present a case of a 62-year-old man with GNTNI. Two adjacent lesions in the left parietal lobe were removed by left parietal craniotomy. The histological findings were glial cell proliferation and scattered rosettes consisting of synaptophysin-positive and NeuN-positive cells, leading to the diagnosis of GNTNI. Target sequencing revealed a genetic alteration similar to glioblastoma, IDH-wild type, which suggested adjuvant therapies. There are few previous reports on the treatment of this disease, and the patient should be followed carefully. en-copyright= kn-copyright= en-aut-name=TsuboiNobushige en-aut-sei=Tsuboi en-aut-mei=Nobushige kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshidaJoji en-aut-sei=Ishida en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimazuYosuke en-aut-sei=Shimazu en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EdakiHisanori en-aut-sei=Edaki en-aut-mei=Hisanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UnedaAtsuhito en-aut-sei=Uneda en-aut-mei=Atsuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=11 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurosurgery, Hamamatsu University School of Medicine kn-affil= affil-num=9 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=glioneuronal tumor with neuropil-like islands kn-keyword=glioneuronal tumor with neuropil-like islands en-keyword= genomic profiling kn-keyword= genomic profiling END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=6 article-no= start-page=1607 end-page=1616 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characterization of the oral and fecal microbiota associated with atopic dermatitis in dogs selected from a purebred Shiba Inu colony en-subtitle= kn-subtitle= en-abstract= kn-abstract=Atopic dermatitis (AD) is a chronic and relapsing multifactorial inflammatory skin disease that also affects dogs. The oral and gut microbiota are associated with many disorders, including allergy. Few studies have addressed the oral and gut microbiota in dogs, although the skin microbiota has been studied relatively well in these animals. Here, we studied the AD-associated oral and gut microbiota in 16 healthy and nine AD dogs from a purebred Shiba Inu colony. We found that the diversity of the oral microbiota was significantly different among the dogs, whereas no significant difference was observed in the gut microbiota. Moreover, a differential abundance analysis detected the Family_XIII_AD3011_group (Anaerovoracaceae) in the gut microbiota of AD dogs; however, no bacterial taxa were detected in the oral microbiota. Third, the comparison of the microbial co-occurrence patterns between AD and healthy dogs identified differential networks in which the bacteria in the oral microbiota that were most strongly associated with AD were related with human periodontitis, whereas those in the gut microbiota were related with dysbiosis and gut inflammation. These results suggest that AD can alter the oral and gut microbiota in dogs. en-copyright= kn-copyright= en-aut-name=UchiyamaJumpei en-aut-sei=Uchiyama en-aut-mei=Jumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OsumiTakafumi en-aut-sei=Osumi en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MizukamiKeijiro en-aut-sei=Mizukami en-aut-mei=Keijiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukuyamaTomoki en-aut-sei=Fukuyama en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShimaAyaka en-aut-sei=Shima en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UnnoAsaka en-aut-sei=Unno en-aut-mei=Asaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=Takemura‐UchiyamaIyo en-aut-sei=Takemura‐Uchiyama en-aut-mei=Iyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UneYumi en-aut-sei=Une en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MurakamiHironobu en-aut-sei=Murakami en-aut-mei=Hironobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SakaguchiMasahiro en-aut-sei=Sakaguchi en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Bacteriology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Veterinary Internal Medicine, Division of Animal Life Science, Graduate School, Tokyo University of Agriculture and Technology kn-affil= affil-num=3 en-affil=School of Veterinary Medicine, Azabu University kn-affil= affil-num=4 en-affil=School of Veterinary Medicine, Azabu University kn-affil= affil-num=5 en-affil=Anicom Specialty Medical Institute Inc. kn-affil= affil-num=6 en-affil=School of Veterinary Medicine, Azabu University kn-affil= affil-num=7 en-affil=Department of Bacteriology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Faculty of Veterinary Medicine, Okayama University of Science kn-affil= affil-num=9 en-affil=School of Veterinary Medicine, Azabu University kn-affil= affil-num=10 en-affil=School of Veterinary Medicine, Azabu University kn-affil= en-keyword=oral kn-keyword=oral en-keyword=gut kn-keyword=gut en-keyword=microbiota kn-keyword=microbiota en-keyword=atopic dermatitis kn-keyword=atopic dermatitis en-keyword=Shiba Inu kn-keyword=Shiba Inu en-keyword=dog colony kn-keyword=dog colony en-keyword=canine kn-keyword=canine END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=8 article-no= start-page=1195 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220722 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Robotic Mediastinal Tumor Resections: Position and Port Placement en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to determine the optimal position and port placement during robotic resection for various mediastinal tumors. For anterior mediastinal tumors, total or extended thymectomy is commonly performed in the supine position using the lateral or subxiphoid approach. Although it is unclear which approach is better during robotic thymectomy, technical advantages of subxiphoid approach are beneficial for patients with myasthenia who require extended thymectomy. Partial thymectomy is performed in the supine position using a lateral approach. Superior, middle, and posterior mediastinal tumors are resected in the decubitus position using the lateral approach, whereas dumbbell tumor resection, which requires a posterior approach, can be performed in the prone position. The position and port placement should be chosen depending on the size, location, and aggressiveness of the tumor. In this study, we describe how to choose which of these different robotic approaches can be used based on our experience and previous reports. en-copyright= kn-copyright= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShienKazuhiko en-aut-sei=Shien en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SuzawaKen en-aut-sei=Suzawa en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= en-keyword=robot kn-keyword=robot en-keyword=robot-assisted thoracic surgery kn-keyword=robot-assisted thoracic surgery en-keyword=mediastinal tumor kn-keyword=mediastinal tumor en-keyword=thymectomy kn-keyword=thymectomy en-keyword=port placement kn-keyword=port placement END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=15 article-no= start-page=8592 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220802 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fibroblast Growth Factors and Cellular Communication Network Factors: Intimate Interplay by the Founding Members in Cartilage en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fibroblast growth factors (FGFs) constitute a large family of signaling molecules that act in an autocrine/paracrine, endocrine, or intracrine manner, whereas the cellular communication network factors (CCN) family is composed of six members that manipulate extracellular signaling networks. FGFs and CCNs are structurally and functionally distinct, except for the common characteristics as matricellular proteins. Both play significant roles in the development of a variety of tissues and organs, including the skeletal system. In vertebrates, most of the skeletal parts are formed and grow through a process designated endochondral ossification, in which chondrocytes play the central role. The growth plate cartilage is the place where endochondral ossification occurs, and articular cartilage is left to support the locomotive function of joints. Several FGFs, including FGF-2, one of the founding members of this family, and all of the CCNs represented by CCN2, which is required for proper skeletal development, can be found therein. Research over a decade has revealed direct binding of CCN2 to FGFs and FGF receptors (FGFRs), which occasionally affect the biological outcome via FGF signaling. Moreover, a recent study uncovered an integrated regulation of FGF and CCN genes by FGF signaling. In this review, after a brief introduction of these two families, molecular and genetic interactions between CCN and FGF family members in cartilage, and their biological effects, are summarized. The molecular interplay represents the mutual involvement of the other in their molecular functions, leading to collaboration between CCN2 and FGFs during skeletal development. en-copyright= kn-copyright= en-aut-name=KubotaSatoshi en-aut-sei=Kubota en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AoyamaEriko en-aut-sei=Aoyama en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakigawaMasaharu en-aut-sei=Takigawa en-aut-mei=Masaharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishidaTakashi en-aut-sei=Nishida en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Biochemistry and Molecular Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Advanced Research Center for Oral and Craniofacial Sciences, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Advanced Research Center for Oral and Craniofacial Sciences, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Biochemistry and Molecular Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=fibroblast growth factor kn-keyword=fibroblast growth factor en-keyword=cellular communication network factor kn-keyword=cellular communication network factor en-keyword=cartilage kn-keyword=cartilage en-keyword=skeletal development kn-keyword=skeletal development en-keyword=CCN2 kn-keyword=CCN2 END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=918226 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220713 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Examining the Role of Low Temperature in Satsuma Mandarin Fruit Peel Degreening via Comparative Physiological and Transcriptomic Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Peel degreening is the most conspicuous aspect of fruit ripening in many citrus fruits because of its importance for marketability. In this study, peel degreening in response to propylene (an ethylene analog) and at varying storage temperatures was characterized in Satsuma mandarin (Citrus unshiu Marc.) fruit. Propylene treatment triggered rapid peel degreening (within 4-6 days), indicated by an increase in the citrus color index (CCI) and chlorophyll loss. Peel degreening was also observed in fruit at 10 degrees C and 15 degrees C after 28-42 days, with gradual CCI increase and chlorophyll reduction. However, fruit at 5 degrees C, 20 degrees C, and 25 degrees C remained green, and no substantial changes in peel CCI and chlorophyll content were recorded during the 42-day storage duration. The transcriptomes of peels of fruit treated with propylene for 4 days and those stored at varying temperatures for 28 days were then analyzed by RNA-Seq. We identified three categories of differentially expressed genes that were regulated by (i) propylene (and by analogy, ethylene) alone, (ii) low temperature (5 degrees C, 10 degrees C, or 15 degrees C vs. 25 degrees C) alone, and (iii) either propylene or low temperature. Gene-encoding proteins associated with chlorophyll degradation (such as CuSGR1, CuNOL, CuACD2, CuCAB2, and CuLHCB2) and a transcription factor (CuERF114) were differentially expressed by propylene or low temperature. To further examine temperature-induced pathways, we also monitored gene expression during on-tree fruit maturation vs. postharvest. The onset of on-tree peel degreening coincided with autumnal drops in field temperatures, and it was accompanied by differential expression of low temperature-regulated genes. On the contrary, genes that were exclusively regulated by propylene (such as CuCOPT1 and CuPOX-A2) displayed insignificant expression changes during on-tree peel degreening. These findings indicate that low temperatures could be involved in the fruit ripening-related peel degreening independently of ethylene. 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=AsicheWilliam O. en-aut-sei=Asiche en-aut-mei=William O. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KangSeung W. en-aut-sei=Kang en-aut-mei=Seung W. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EzuraHiroshi en-aut-sei=Ezura en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AkagiTakashi en-aut-sei=Akagi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KuboYasutaka en-aut-sei=Kubo en-aut-mei=Yasutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Research and Development, Del Monte Kenya Ltd kn-affil= affil-num=3 en-affil=Graduate School of Life and Environmental Sciences, University of Tsukuba kn-affil= affil-num=4 en-affil=Graduate School of Life and Environmental Sciences, University of Tsukuba kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=chlorophyll kn-keyword=chlorophyll en-keyword=citrus kn-keyword=citrus en-keyword=degreening kn-keyword=degreening en-keyword=ethylene kn-keyword=ethylene en-keyword=RNA-Seq kn-keyword=RNA-Seq en-keyword=on-tree kn-keyword=on-tree en-keyword=storage kn-keyword=storage END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=7 article-no= start-page=104524 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220715 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lattice-patterned collagen fibers and their dynamics in axolotl skin regeneration en-subtitle= kn-subtitle= en-abstract= kn-abstract=The morphology of collagen-producing cells and the structure of produced collagen in the dermis have not been well-described. This lack of insights has been a serious obstacle in the evaluation of skin regeneration. We succeeded in visualizing collagen-producing cells and produced collagen using the axolotl skin, which is highly transparent. The visualized dermal collagen had a lattice-like structure. The collagen-producing fibroblasts consistently possessed the lattice-patterned filopodia along with the lattice-patterned collagen network. The dynamics of this lattice-like structure were also verified in the skin regeneration process of axolotls, and it was found that the correct lattice-like structure was not reorganized after simple skin wounding but was reorganized in the presence of nerves. These findings are not only fundamental insights in dermatology but also valuable insights into the mechanism of skin regeneration. en-copyright= kn-copyright= en-aut-name=KashimotoRena en-aut-sei=Kashimoto en-aut-mei=Rena kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurukawaSaya en-aut-sei=Furukawa en-aut-mei=Saya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamamotoSakiya en-aut-sei=Yamamoto en-aut-mei=Sakiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KameiYasuhiro en-aut-sei=Kamei en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakamotoJoe en-aut-sei=Sakamoto en-aut-mei=Joe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NonakaShigenori en-aut-sei=Nonaka en-aut-mei=Shigenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WatanabeTomonobu M. en-aut-sei=Watanabe en-aut-mei=Tomonobu M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SakamotoTatsuya en-aut-sei=Sakamoto en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SakamotoHirotaka en-aut-sei=Sakamoto en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SatohAkira en-aut-sei=Satoh en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Division of Earth, Life, and Molecular Sciences, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Biological Sciences, Faculty of Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Biological Sciences, Faculty of Science, Okayama University kn-affil= affil-num=4 en-affil=National Institute for Basic Biology (NIBB), National Institutes for Natural Sciences kn-affil= affil-num=5 en-affil=National Institute for Basic Biology (NIBB), National Institutes for Natural Sciences kn-affil= affil-num=6 en-affil=National Institute for Basic Biology (NIBB), National Institutes for Natural Sciences kn-affil= affil-num=7 en-affil=Laboratory for Comprehensive Bioimaging, RIKEN Center for Biosystems Dynamics Research (BDR) kn-affil= affil-num=8 en-affil=Division of Earth, Life, and Molecular Sciences, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Division of Earth, Life, and Molecular Sciences, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=10 en-affil=Research Core for Interdisciplinary Sciences (RCIS), Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=535 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220702 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Diffuse myometrium thinning and placenta accreta spectrum in a patient with systemic lupus erythematosus (SLE): a case report and review of the literature en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background : Cases of uterine wall thinning and placental abnormalities complicated with systemic lupus erythematosus (SLE) during pregnancy have been reported in Asian countries for ten years. Long-term steroid use can cause muscle degeneration, but the mechanism of myometrium thinning was not known. Through the review of published articles, this report is the first review of cases to discuss the pathogenesis and clinical features of thinned myometrium and placenta accreta spectrum (PAS) in pregnant patients with SLE.
Case presentation : A twenty-nine-year-old primigravida with a history of lupus enteritis and paralytic ileus had a natural conception after less than two years of steroid treatment. An ultrasonographic study showed a thin uterine wall with a widespread thick placenta on the entire surface of the uterine cavity in the third trimester. At the 39th gestational week, she underwent a cesarean section due to the failure of the uterus to contract, even though the injection of oxytocin. There were several engorged vessels on the surface of the anterior uterine wall at the time of laparotomy. We decided to perform a hysterectomy because diffuse PAS replaced her uterus.
Conclusion : A review of reported cases and our case shows an unusual complication of SLE that might be related to the particular condition of the estrogen-mediated immune system. Clinicians should always pay attention to the possibility of uterine wall thinning as uterine atony and the structural abnormality of the placenta for SLE patients with the unscarred uterus. en-copyright= kn-copyright= en-aut-name=MitomaTomohiro en-aut-sei=Mitoma en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayataKei en-aut-sei=Hayata en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YokohataSatomi en-aut-sei=Yokohata en-aut-mei=Satomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OhiraAkiko en-aut-sei=Ohira en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KashinoChiaki en-aut-sei=Kashino en-aut-mei=Chiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KirinoSatoe en-aut-sei=Kirino en-aut-mei=Satoe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TaniKazumasa en-aut-sei=Tani en-aut-mei=Kazumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MakiJota en-aut-sei=Maki en-aut-mei=Jota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=EtoEriko en-aut-sei=Eto en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Department of Obstetrics and Gynecology, Okayama University kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Department of Obstetrics and Gynecology, Okayama University kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Department of Obstetrics and Gynecology, Okayama University kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Department of Obstetrics and Gynecology, Okayama University kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Department of Obstetrics and Gynecology, Okayama University kn-affil= affil-num=6 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Department of Obstetrics and Gynecology, Okayama University kn-affil= affil-num=7 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Department of Obstetrics and Gynecology, Okayama University kn-affil= affil-num=8 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Department of Obstetrics and Gynecology, Okayama University kn-affil= affil-num=9 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Department of Obstetrics and Gynecology, Okayama University kn-affil= affil-num=10 en-affil=Department of Obstetrics and Gynecology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Department of Obstetrics and Gynecology, Okayama University kn-affil= en-keyword=Lupus kn-keyword=Lupus en-keyword=Myometrium kn-keyword=Myometrium en-keyword=Placenta accreta spectrum kn-keyword=Placenta accreta spectrum en-keyword=Estrogen kn-keyword=Estrogen en-keyword=Uterine atony kn-keyword=Uterine atony END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=3 article-no= start-page=333 end-page=338 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202206 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Successful Treatment of Atypical Femoral Fracture with Bowed Femur Using Contralateral Intramedullary Nail Combined with Early Daily Teriparatide en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a case of atypical femoral fracture achieving early fracture union with combination therapy comprising contralateral nail and immediate teriparatide injection.

All cases were fixed with malalignment. In AFF patients, postoperative changes due to postoperative femoral bone malalignment may affect the peri-implant mechanical environment around the femoral neck, which can result in insufficiency fractures.

In general, axial flux machines (AFMs) are more suitable for flat form than radial flux machines (RFMs). AFMs usually employ a soft magnetic composite (SMC) for the stator core, and their efficiency can be improved by employing an SMC that has low iron loss. However, this reduces the average torque because there is generally a tradeoff relationship between iron loss and magnetic permeability in SMCs. This article, therefore, proposes an AFM with a coreless rotor structure in which the torque performance is not easily affected by the permeability of the SMC. This article aims to reveal the ideal SMC characteristics for high efficiency in AFMs. First, many virtual SMC materials with different iron loss and permeability are used for simulations of AFMs in order to investigate sensitivity to material properties. The simulations by virtual SMCs take into account the experimental increase in the iron loss. As a result, guidelines for developing SMCs are constructed based on the experimental results. Finally, prototype AFMs employing new SMCs developed by following the guidelines are shown, and it is found that they offer higher efficiency in all operating area than conventional AFMs. In particular, one prototype achieves an extremely high efficiency of over 96% at 6000 r/min, 0.8 Nm in experiments. en-copyright= kn-copyright= en-aut-name=TsunataRen en-aut-sei=Tsunata en-aut-mei=Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakemotoMasatsugu en-aut-sei=Takemoto en-aut-mei=Masatsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OgasawaraSatoshi en-aut-sei=Ogasawara en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoTatsuya en-aut-sei=Saito en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UenoTomoyuki en-aut-sei=Ueno en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Division of Industrial Innovation Sciences Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Industrial Innovation Sciences Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Information Science and Technology, Hokkaido University kn-affil= affil-num=4 en-affil=Sumitomo Electric Industries Ltd. kn-affil= affil-num=5 en-affil=Sumitomo Electric Industries Ltd. kn-affil= END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=37 article-no= start-page=e202201253 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220523 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Design and Synthesis of Glycosylated Cholera Toxin B Subunit as a Tracer of Glycoprotein Trafficking in Organelles of Living Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Glycosylation of proteins is known to be essential for changing biological activity and stability of glycoproteins on the cell surfaces and in body fluids. Delivering of homogeneous glycoproteins into the endoplasmic reticulum (ER) and the Golgi apparatus would enable us to investigate the function of asparagine-linked (N-) glycans in the organelles. In this work, we designed and synthesized an intentionally glycosylated cholera toxin B-subunit (CTB) to be transported to the organelles of mammalian cells. The heptasaccharide, the intermediate structure of various complex-type N-glycans, was introduced to the CTB. The synthesized monomeric glycosyl-CTB successfully entered mammalian cells and was transported to the Golgi and the ER, suggesting the potential use of synthetic CTB to deliver and investigate the functions of homogeneous N-glycans in specific organelles of living cells. en-copyright= kn-copyright= en-aut-name=MakiYuta en-aut-sei=Maki en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawataKazuki en-aut-sei=Kawata en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LiuYanbo en-aut-sei=Liu en-aut-mei=Yanbo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GooKang‐Ying en-aut-sei=Goo en-aut-mei=Kang‐Ying kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkamotoRyo en-aut-sei=Okamoto en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KajiharaYasuhiro en-aut-sei=Kajihara en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SatohAyano en-aut-sei=Satoh en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Chemistry, Graduate School of Science, Osaka University kn-affil= affil-num=2 en-affil=Department of Chemistry, Graduate School of Science, Osaka University kn-affil= affil-num=3 en-affil=Department of Chemistry, Graduate School of Science, Osaka University kn-affil= affil-num=4 en-affil=Department of Chemistry, Graduate School of Science, Osaka University kn-affil= affil-num=5 en-affil=Department of Chemistry, Graduate School of Science, Osaka University kn-affil= affil-num=6 en-affil=Department of Chemistry, Graduate School of Science, Osaka University kn-affil= affil-num=7 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=glycoprotein kn-keyword=glycoprotein en-keyword=N-glycan kn-keyword=N-glycan en-keyword=cholera toxin kn-keyword=cholera toxin en-keyword=native chemical ligation kn-keyword=native chemical ligation en-keyword=live imaging kn-keyword=live imaging END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=294 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220612 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Endoscopic features of oxyntic gland adenoma and gastric adenocarcinoma of the fundic gland type differ between patients with and without Helicobacter pylori infection: a retrospective observational study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background The endoscopic features of oxyntic gland adenoma and gastric adenocarcinoma of the fundic gland type have not been fully investigated in relation to Helicobacter pylori infection status. We compared the morphology, color, and location of these lesions between patients with and without H. pylori infection. Methods We retrospectively enrolled 165 patients (180 lesions) from 10 institutions. We divided the patients into the (i) Hp group (patients with current H. pylori infection [active gastritis, n = 13] and those with past infection [inactive gastritis, n = 76]) and (ii) uninfected group (H. pylori-uninfected patients, n = 52). We compared the clinical and endoscopic features of the two groups. We also performed an analysis between (i) lesions with atrophy of the surrounding gastric mucosa (atrophy group) and (ii) lesions without atrophy of the surrounding gastric mucosa (non-atrophy group). Results The average age was older in the Hp group than in the uninfected group (68.1 +/- 8.1 vs. 63.4 +/- 8.7 years, p < 0.01). Although the difference was not statistically significant (p = 0.09), multiple lesions were observed in 9 of 89 patients (10.1%) in the Hp group and in only 1 of 52 patients (1.9%) in the uninfected group. Meanwhile, significant differences were observed in the prevalence of lesions located in the gastric fornix or cardia (uninfected group: 67.3% vs. Hp group: 38.0%, p < 0.01), with an elevated morphology (80.0% vs. 56.0%, p < 0.01), with a subepithelial-like appearance (78.2% vs. 42.0%, p < 0.01), and with a color similar to that of the peripheral mucosa (43.6% vs. 25.0%, p = 0.02). The male-to-female ratio, lesion size, and presence or absence of vascular dilatation or black pigmentation on the surface were not different between the two groups. In the analysis comparing lesions with and without mucosal atrophy, the prevalence of multiple lesions was significantly higher (p = 0.02) in the atrophy group (5/25 patients, 20.0%) than in the non-atrophy group (7/141 patients, 5.0%). Conclusions The endoscopic features of oxyntic gland adenoma and gastric adenocarcinoma of the fundic gland type differ between patients with and without H. pylori infection. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KusumotoChiaki en-aut-sei=Kusumoto en-aut-mei=Chiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakagawaMasahiro en-aut-sei=Nakagawa en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsuedaKazuhiro en-aut-sei=Matsueda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobayashiSayo en-aut-sei=Kobayashi en-aut-mei=Sayo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshiokaMasao en-aut-sei=Yoshioka en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=InabaTomoki en-aut-sei=Inaba en-aut-mei=Tomoki 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=SakaguchiChihiro en-aut-sei=Sakaguchi en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaShouichi en-aut-sei=Tanaka en-aut-mei=Shouichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology, Nippon Kokan Fukuyama Hospital kn-affil= affil-num=3 en-affil=Department of Endoscopy, Hiroshima City Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Kurashiki Central Hospital kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Fukuyama City 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, Fukuyama Medical Center kn-affil= affil-num=9 en-affil=Department of Endoscopy, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=10 en-affil=Department of Gastroenterology, Iwakuni Clinical Center kn-affil= affil-num=11 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Gastric neoplasms kn-keyword=Gastric neoplasms en-keyword=Oxyntic gland adenoma kn-keyword=Oxyntic gland adenoma en-keyword=Gastric adenocarcinoma of the fundic gland type kn-keyword=Gastric adenocarcinoma of the fundic gland type END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=4 article-no= start-page=1194 end-page=1200 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=2022411 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dip-and-Read, Organic Solvent-Compatible, Paper-Based Analytical Devices Equipped with Chromatographic Separation for Indole Analysis in Shrimp en-subtitle= kn-subtitle= en-abstract= kn-abstract=We developed an organic solvent-compatible paper-based analytical device (PAD) for the quantitative analysis of indole, which is an indicator of shrimp freshness. Although indole is insoluble in water, ethyl acetate is a suitable solvent to dissolve and extract indole from shrimp. The PADs are fabricated using a cutting method that allows the use of an organic solvent because no hydrophobic barrier is needed to form fluidic channels. Ehrlich's reagent consists of 4-(dimethylamino)benzaldehyde and p-dimethylaminobenzaldehyde and was deposited onto the reaction zone of the PAD followed by lamination to prevent evaporation of the ethyl acetate. Samples are introduced into the PAD via immersion in organic sample solutions. When the PAD is immersed into an indole solution of ethyl acetate in a closed bottle, the sample solution penetrates the channel of the PAD and successively flows into the detection zone to form a hydrophilic colored product. The PADs provide a linear relationship between the logarithm of the indole concentration and the color intensity within a range of 1.0-20 ppm with correlation coefficients of r2 > 0.99. The limits of detection and quantification are 0.36 and 0.71 ppm, respectively. Relative standard deviations for both the intraday (n = 2) and interday (n = 3) precision were less than 2.5%. In the indole analysis of shrimp, the PADs separated the interfering orange-colored astaxanthin in the extract from the colored product of indole via the paper chromatographic principle. We used the PADs to investigate the degradation of shrimp, and the results showed a rapid increase in the indole level after 7 days. High-performance liquid chromatography verified the accuracy of the PADs by showing good agreement with the obtained indole levels. 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=Ehrlich’s reagent kn-keyword=Ehrlich’s reagent en-keyword=astaxanthin kn-keyword=astaxanthin en-keyword=chromatography kn-keyword=chromatography en-keyword=indole kn-keyword=indole en-keyword=paper-based device kn-keyword=paper-based device en-keyword=shrimp kn-keyword=shrimp 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=2021 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Microfluidic Paper-based Analytical Devices Coupled with Coprecipitation Enrichment Show Improved Trace Analysis of Copper Ions in Water Samples en-subtitle= kn-subtitle= en-abstract= kn-abstract=The present study was focused on improving sensitivity to trace levels of Cu(II) by subjecting microfluidic paper based analytical devices (μ PADs) to a preconcentration process via coprecipitation using aluminum hydroxide. The experimental conditions were optimized for the pH of the coprecipitation, centrifugation, and amounts of reagents that were deposited onto µ PADs for Cu(II) assay. The resultant limit of detection reached as low as 0.003 mg L 1 with a linear range of 0.01 2.00 mg L 1 . The relative standard deviations for intra and inter day precision were 3.2 and 4.6%, respectively (n = 9). Spiked water samples were analyzed using the μ PADs after coprecipitation preconcentration. The results were verified by comparing them with thos e of inductively coupled plasma optical emission spectrometry (ICP OES). Recoveries ranged from 97.1 104% and from 98.7 105% using the present method and ICP OES, respectively. These results suggest that the simple, highly sensitive, and inexpensive propos ed method would be helpful for analyzing trace levels of Cu(II) in water samples in poorly equipped laboratories. en-copyright= kn-copyright= en-aut-name=MUHAMMEDAbdellah en-aut-sei=MUHAMMED en-aut-mei=Abdellah kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HUSSENAhmed en-aut-sei=HUSSEN en-aut-mei=Ahmed kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanetaTakashi en-aut-sei=Kaneta en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Center for Environmental Science, College of Natural and Computational Sciences, Addis Ababa University kn-affil= affil-num=2 en-affil=Center for Environmental Science, College of Natural and Computational Sciences, Addis Ababa University kn-affil= affil-num=3 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Microfluidic paper based analytical device kn-keyword=Microfluidic paper based analytical device en-keyword=Coprecipitation kn-keyword=Coprecipitation en-keyword=Preconcentration kn-keyword=Preconcentration en-keyword=Aluminum hydroxide kn-keyword=Aluminum hydroxide en-keyword=Copperion kn-keyword=Copperion en-keyword=bathocuproine kn-keyword=bathocuproine END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=トモシンセシスによるイリザロフ式骨延長ボルト装着患者に対する撮影方法と再構成方法の検討 kn-title=Evaluation of Patient Positioning During Digital Tomosynthesis and ReconstructionAlgorithms for Ilizarov Frames: A Phantom Study en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=AbeYuki en-aut-sei=Abe en-aut-mei=Yuki kn-aut-name=阿部勇輝 kn-aut-sei=阿部 kn-aut-mei=勇輝 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil=岡山大学大学院保健学研究科 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=2022 dt-pub=20220325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=六倍体栽培ガキにおける性の揺らぎの分子機構 kn-title=Molecular mechanisms for plastic sex expression in hexaploid persimmon en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MasudaKanae en-aut-sei=Masuda en-aut-mei=Kanae kn-aut-name=増田佳苗 kn-aut-sei=増田 kn-aut-mei=佳苗 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=2022 dt-pub=20220325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=破骨細胞形成・分化におけるRab11bの抑制的役割 kn-title=The Inhibitory Role of Rab11b in Osteoclastogenesis through Triggering Lysosome-Induced Degradation of c-Fms and RANK Surface Receptors en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Tran Tien Manh en-aut-sei=Tran Tien Manh 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 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=2022 dt-pub=20220325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=日本の自立高齢者における口腔機能、栄養状態および身体機能の関係 kn-title=Oral function, nutritional status and physical status in Japanese independent older adults en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=SawadaNanami en-aut-sei=Sawada en-aut-mei=Nanami kn-aut-name=澤田ななみ kn-aut-sei=澤田 kn-aut-mei=ななみ 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=2022 dt-pub=20220325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=非アルコール性脂肪肝炎患者口腔由来 Streptococcus mutans の病態発症関連因子の解析 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=TabataKeiko en-aut-sei=Tabata en-aut-mei=Keiko kn-aut-name=田畑佳子 kn-aut-sei=田畑 kn-aut-mei=佳子 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
