However, general metamaterials have a risk of deformations and degradation at high temperatures in atmospheric conditions, which is inconvenient for use as a thermal emitter. In this study, we propose a concept to enhance the thermal durability of microcavity-type metamaterials. Although typical microcavities are entirely composed of metal to excite the resonance of electromagnetic waves, we assessed the feasibility of a microcavity consisting of silicon with minimal metal coatings. While usual metals are oxidized at high temperatures, gold is rarely oxidized due to its chemical stability. However, the gold layer deposited on the Si substrate has the potential to melt below 400 °C due to the formation of an Au-Si eutectic alloy, which has a much lower melting point than pure gold. Therefore, we focused on the gold-tungsten bilayer as a suitable metal coating for the silicon microcavity, thereby preventing oxidation and melting that would otherwise influence the emission spectra of the thermal emitter. The numerical analysis ensured that the proposed microcavity exhibited electromagnetic resonance, similar to that of a microcavity entirely composed of metal, unless the metal coating was too thin. The fabricated microcavity with the gold-tungsten coating also exhibited a thermal emission within a limited wavelength range, due to the microcavity resonance. Moreover, the heating experiment revealed that the microcavity with a gold-tungsten coating maintained its emissivity even when heated to 400 °C, which is higher than the oxidation point of tungsten and the melting point of the Au-Si eutectic alloy. Consequently, the gold-tungsten coating would be a reasonable approach to improve the stability of the microcavity-type metamaterial at high temperatures under oxidative conditions. en-copyright= kn-copyright= en-aut-name=IsobeKazuma en-aut-sei=Isobe en-aut-mei=Kazuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorishigeShota en-aut-sei=Morishige en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoTaiyo en-aut-sei=Sato en-aut-mei=Taiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamadaYutaka en-aut-sei=Yamada en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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 Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Metamaterial kn-keyword=Metamaterial en-keyword=Microcavity emitter kn-keyword=Microcavity emitter en-keyword=Emissivity spectrum kn-keyword=Emissivity spectrum en-keyword=Thermal stability kn-keyword=Thermal stability en-keyword=Tungsten oxidation kn-keyword=Tungsten oxidation en-keyword=Eutectic melting kn-keyword=Eutectic melting END start-ver=1.4 cd-journal=joma no-vol=283 cd-vols= no-issue=2 article-no= start-page=78 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Simons Observatory: Detector Polarization Angle Calibration Using a Sparse Wire Grid with Initial Datasets of the Small-aperture Telescopes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Improved measurements of B-modes in the cosmic microwave background can be obtained through accurate calibration of the orientation of detector antennas as projected onto the sky. Miscalibration of the detector polarization angle leads to a leakage of E-modes into B-modes, which can bias the detection of the latter. To achieve a σ(r) of 0.003, the Simons Observatory small-aperture telescopes are required to calibrate the global polarization angle on the sky with an accuracy ?0.°1. We demonstrate a fully remote-controllable calibration system using a “sparse wire grid,” which injects a rotatable linear polarized signal across the telescope’s focal plane. This calibration system is installed and operational on one of the small-aperture telescopes at its observing site at the Parque Astron?mico in the Atacama desert in Chile. We developed a pipeline for the detector polarization angle calibration, and demonstrate it using initial data for 93 and 145 GHz frequency bands. The observed distribution of detector polarization angles is in agreement with the instrument design. Statistical uncertainties for the relatively calibrated polarization angles are 0.°02 and 0.°03 at 93 and 145 GHz, respectively. Systematic uncertainty was evaluated to be 0.°08 at the hardware development and fabrication stage. Their sum in quadrature is less than 0.°1. en-copyright= kn-copyright= en-aut-name=NakataHironobu en-aut-sei=Nakata en-aut-mei=Hironobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

Detectability of Body Wave Phases From Tidal Ice Cracking Events on Titan With the Dragonfly Short-Period Seismometer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Detecting seismic activity on Saturn's icy moon Titan during the Dragonfly mission could provide crucial information on its internal structure. The geological complexity of the moon's surface suggests significant cyclic tidal deformation, likely leading to the fracturing of the ice shell. Considering realistic source locations and fault geometries, we assess whether a vertical short-period seismometer can detect body waves from a Mw 4.0 icequake. Signal-to-noise ratios are evaluated by comparing the high-frequency content with the expected background noise and instrument capabilities for several ice attenuation scenarios and 1D interior models. Our results indicate that the high-frequency content (?1Hz) of Mw?4.0 tidal-induced icequakes is likely undetectable under the most unfavorable attenuation scenarios and atmospheric conditions. However, seismic signals in the 0.5?1 Hz band?where P wave reflections dominate?may still be observable for events occurring in potential seismically active regions at ?800?1,000 km from the Dragonfly's landing site. These signals could provide constraints on the thickness of Titan's outer ice shell, provided that intrinsic attenuation is low and environmental conditions are favorable. en-copyright= kn-copyright= en-aut-name=DelaroqueL. en-aut-sei=Delaroque en-aut-mei=L. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawamuraT. en-aut-sei=Kawamura en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LucasA. en-aut-sei=Lucas en-aut-mei=A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=RodriguezS. en-aut-sei=Rodriguez en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OnoderaK. en-aut-sei=Onodera en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShiraishiH. en-aut-sei=Shiraishi en-aut-mei=H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamadaR. en-aut-sei=Yamada en-aut-mei=R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TanakaS. en-aut-sei=Tanaka en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=PanningM.

Zinc transporter 1 (ZnT1) is a ubiquitously expressed plasma membrane-localized Zn transporter that exports Zn2+ from the cytoplasm to the extracellular space. However, the functional transport properties regarding kinetics and driving forces of ZnT1 remain debatable. In this study, we established a cell-free proteoliposome assay system and demonstrated that ZnT1 transports Zn2+ with high affinity in pH-dependent and pH-independent manners. The Km and Vmax of pH-dependent Zn2+ transport were 0.40 μM and 15.13 nmol/min/mg protein, and those of pH-independent Zn2+ transport were 0.52 μM and 8.88 nmol/min/mg protein (low concentrations of Zn2+), 3.02 μM and 17.59 nmol/min/mg protein (high concentrations of Zn2+), respectively, suggesting biphasic kinetic components of Zn2+ transport. Even without pH gradient formation, ZnT1 exhibits potent Zn2+ transport activity. In pH dependency, Zn2+ transport activity was higher at an inside pH of 6.0 than at 6.5?7.5 for proteoliposomes, despite the same ΔpH of 0.5?1.5. The Zn2+ transport activity decreased at an outside pH of 8.0, despite an increase in ΔpH. Although previous studies have proposed that ZnT1-mediated Zn2+ transport activity is driven by a calcium (Ca2+) gradient and not by a pH gradient, Ca2+ does not enhance Zn2+ transport activity in the presence or absence of a pH gradient. These results strongly suggest that ZnT1 protein transports Zn2+ optimally at a specific pH and exports excess intracellular Zn2+ even without ΔpH. en-copyright= kn-copyright= en-aut-name=YoshiokaYuma en-aut-sei=Yoshioka en-aut-mei=Yuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyajiTakaaki en-aut-sei=Miyaji en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Molecular Membrane Biology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Molecular Membrane Biology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=zinc transporter 1 kn-keyword=zinc transporter 1 en-keyword=SLC30A1 kn-keyword=SLC30A1 en-keyword=zinc kn-keyword=zinc en-keyword=pH kn-keyword=pH en-keyword=proteoliposome kn-keyword=proteoliposome END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=7 article-no= start-page=810 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260326 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Universal Adhesives on Resin Cement?Fiber Post?Core Materials en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study evaluated eleven resin cements used as core build-up materials by examining the following properties: (a) push-out force between root dentin and the fiber post; (b) pull-out force between the fiber post and the core build-up material; (c) shear bond strength of the resin cement to root dentin; (d) flexural strength of the resin cement; and (e) flexural modulus of elasticity of the resin cement. The purpose of this investigation was to clarify the relationships between recently available universal adhesives, core build-up materials, resin cements, and fiber posts. All experiments were performed at two evaluation periods: after 1 day of water storage (Base) and after 20,000 thermocycles (TC 20k). For the push-out test, simulated post spaces were prepared in single-rooted human premolars. The specimens were sectioned perpendicular to the long axis into 2 mm-thick slices and then subjected to push-out testing to assess the bond strength of the dentin?resin cement?fiber post complex. No significant differences in bonding performance were found between Base and TC 20k. These findings suggest that universal adhesives used for pretreatment of multiple substrates in fiber post cementation can provide not only strong but also durable adhesion over time. en-copyright= kn-copyright= en-aut-name=IrieMasao en-aut-sei=Irie en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkadaMasahiro en-aut-sei=Okada en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaruoYukinori en-aut-sei=Maruo en-aut-mei=Yukinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AkiyamaKenraro en-aut-sei=Akiyama en-aut-mei=Kenraro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshiharaKumiko en-aut-sei=Yoshihara en-aut-mei=Kumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsujimotoAkimasa en-aut-sei=Tsujimoto en-aut-mei=Akimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoTakuya en-aut-sei=Matsumoto en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Dental Biomaterials, Graduate School of Dentistry, Tohoku University kn-affil= affil-num=3 en-affil=Department of Prosthodontics, Okayama University kn-affil= affil-num=4 en-affil=Department of Occlusal and Oral Functional Rehabilitation, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Health Research Institute, National Institute of Advanced Industrial Science and Technology kn-affil= affil-num=6 en-affil=Department of Operative Dentistry, School of Dentistry, Aichi Gakuin University kn-affil= affil-num=7 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=bonding performance kn-keyword=bonding performance en-keyword=universal adhesive kn-keyword=universal adhesive en-keyword=fiber post kn-keyword=fiber post en-keyword=luting materials kn-keyword=luting materials en-keyword=root dentin kn-keyword=root dentin END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=2 article-no= start-page=831 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260114 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Porphyromonas gingivalis Vesicles Control Osteoclast?Macrophage Lineage Fate en-subtitle= kn-subtitle= en-abstract= kn-abstract=Porphyromonas gingivalis (Pg), a keystone pathogen of chronic periodontitis, releases outer membrane vesicles (OMVs) that act as nanoscale vehicles to disseminate virulence factors within periodontal tissues and systemically beyond the oral cavity. Although Pg-OMVs are increasingly recognized as critical mediators of host?pathogen interactions, their effects on the differentiation and function of monocyte?macrophage/osteoclast lineage cells remain unclear. Here, we examined the impact of Pg-OMVs on the differentiation of RAW264.7 monocyte/macrophage-like cells into osteoclasts (OC) and/or macrophages (MΦ) in the presence of receptor activator of nuclear factor-κB ligand (RANKL). OMVs were isolated from Pg W83 and applied to RANKL-primed RAW264.7 cells using three distinct stimulation schedules: (1) simultaneous treatment with Pg-OMVs and RANKL at Day 0; (2) RANKL priming at Day 0 followed by Pg-OMV stimulation at Day 1; and (3) RANKL priming at Day 0 followed by Pg-OMV stimulation at Day 3. In all schedules, cells were cultured for 7 days from the initial RANKL exposure. Remarkably, simultaneous exposure to Pg-OMVs and RANKL (Schedule 1) markedly suppressed osteoclastogenesis (OC-genesis) while promoting M1 macrophage polarization. In contrast, delayed Pg-OMV stimulation of RANKL-primed cells (Schedules 2 and 3) significantly enhanced OC-genesis while reducing M1 polarization. These schedule-dependent effects were consistent with altered expression of osteoclastogenic markers, including dc-stamp, oc-stamp, nfatc1, and acp5. Importantly, a monoclonal antibody against OC-STAMP counteracted the Pg-OMV-induced upregulation of OC-genesis in Schedules 2 and 3. Furthermore, levels of Pg-OMV phagocytosis were inversely correlated with osteoclast formation. Finally, co-stimulation with RANKL and Pg-OMVs (Schedule 1) enhanced macrophage migratory capacity, whereas delayed stimulation with Pg-OMVs (Schedules 2 and 3) did not. Collectively, these findings indicate that Pg-OMVs exert stage-specific effects on the OC/MΦ lineage: stimulation at early stages of RANKL priming suppresses OC-genesis and promotes M1 polarization, whereas stimulation at later stages enhances OC-genesis without inducing M1 differentiation. Thus, Pg-OMVs may critically influence the fate of the OC/MΦ unit in periodontal lesions, contributing to disease progression and tissue destruction. en-copyright= kn-copyright=

enhances apoplastic flow, resulting in an increment of Na+ uptake and a lower K+/Na+ ratio. Salicylic acid (SA) plays an important role in improving salinity tolerance in plants. The effect of exogenous SA on apoplastic flow in salt-treated rice seedlings was studied using an apoplastic tracer, 8-hydroxy-1,3,6-pyrenetrisulphonic acid (PTS) in light. Application of NaCl at 25 mM to the hydroponic solution significantly increased PTS uptake, while 25 mM NaCl did not affect seedling growth. Application of 25 mM NaNO3 increased PTS uptake to the same degree. Salinity significantly increased sodium (Na+) content but had no significant effect on potassium (K+) content, resulting in a lower K+/Na+ ratio. The application of SA at 0.05 mM and 0.1 mM to the hydroponic solution reduced Na-enhanced PTS uptake. Salicylic acid at 0.05 mM and 0.1 mM significantly reduced Na+ content and slightly increased K+ content in the shoots of rice seedlings, resulting in a higher K+/Na+ ratio. However, SA at up to 0.1 mM did not increase SA contents in shoots under salt stress. These results suggest that exogenous SA reduces Na+ uptake by suppressing Na+-enhanced apoplastic flow in rice seedlings. These findings provide insight into modulation of Na+ transport pathways from roots to shoots by SA and may allow us to utilize brackish water for rice cultivation and to improve salt-tolerant rice through suppression of salt-enhanced apoplastic flow by chemicals such as salicylic acid. en-copyright= kn-copyright= en-aut-name=GalibMd.

It remains uncertain how water is stored in subducting slabs within the mantle transition zone, between depths of about 410 and 660 kilometers, and whether dense hydrous magnesium silicates act as major water carriers to greater depths. Here we report high-pressure and high-temperature laboratory experiments on the Mg-Si-H system at pressures of 16 and 21.5?GPa and a temperature of 1400?K to evaluate hydrous phase stability under transition zone conditions. We find that when bulk water content is below 1.22?wt%, H2O is predominantly incorporated into wadsleyite and ringwoodite rather than forming dense hydrous magnesium silicates. Because estimated water contents in subducted oceanic slabs are typically lower than one weight percent, formation of these silicates is unlikely, suggesting that the mantle transition zone may restrict large scale water transport into the lower mantle. en-copyright= kn-copyright= en-aut-name=SongYunke en-aut-sei=Song en-aut-mei=Yunke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GuoXinzhuan en-aut-sei=Guo en-aut-mei=Xinzhuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ZhaiKuan en-aut-sei=Zhai en-aut-mei=Kuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GuoWei en-aut-sei=Guo en-aut-mei=Wei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshinoTakashi en-aut-sei=Yoshino en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Key Laboratory of High-temperature and High-pressure Study of the Earth’s Interior, Institute of Geochemistry, Chinese Academy of Sciences kn-affil= affil-num=2 en-affil=State Key Laboratory of Critical Mineral Research and Exploration, Institute of Geochemistry, Chinese Academy of Sciences kn-affil= affil-num=3 en-affil=Key Laboratory of High-temperature and High-pressure Study of the Earth’s Interior, Institute of Geochemistry, Chinese Academy of Sciences kn-affil= affil-num=4 en-affil=State Key Laboratory of Geomicrobiology and Environmental Changes, School of Earth Sciences, China University of Geosciences (Wuhan) kn-affil= affil-num=5 en-affil=Institute for Planetary Materials, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=171 cd-vols= no-issue=2 article-no= start-page=xaag004 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Rho kinase and RND3 regulate the direct effect of estradiol-17β on oviductal tonus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ensuring the timely transport of gametes and embryos within the oviduct is essential for the successful establishment of pregnancy. This study investigated the direct effect of estradiol-17β (E2) on bovine oviductal contractility and the differences in responsiveness to E2 during the estrous cycle. Bovine isthmic tissues from four estrous stages were analyzed using the Magnus method to assess contractile responses to E2 and related reagents. Protein expression of G-protein-coupled estrogen receptor 1 (GPER1) and components of the RhoA/Rho kinase (ROCK) signaling pathway were also evaluated. E2 and a GPER1 agonist significantly increased oviductal tonus at 1?4?days after ovulation. This effect was significantly suppressed by treatment with a GPER1 antagonist and a ROCK inhibitor. At 1?4?days after ovulation, both ROCK II expression and ROCK activity were elevated. E2 also enhanced phosphorylation of myosin phosphatase targeting subunit 1 (MYPT1) and myosin light chain (MLC), key downstream targets of ROCK. Before ovulation, when endogenous E2 levels peak, the expression of RND3?a ROCK inhibitor?was upregulated. The application of an RND inhibitor restored E2 responsiveness in oviductal tonus, ROCK activity, and the phosphorylation of MYPT1 and MLC in oviductal tissues before ovulation. These findings suggest that E2 directly increases oviductal tonus via GPER1 and ROCK/MYPT1/MLC activation at 1?4?days after ovulation. Differences in oviductal responsiveness to E2 during the estrous cycle appear to be mediated by the expression of ROCK and RND3. This mechanism can enable sperm transport within the oviduct at an appropriate time. en-copyright= kn-copyright= en-aut-name=KubotaSayaka en-aut-sei=Kubota en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkawaraRisa en-aut-sei=Okawara en-aut-mei=Risa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawanoKohei en-aut-sei=Kawano en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KimuraKoji en-aut-sei=Kimura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=School of Agriculture, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=estradiol-17β kn-keyword=estradiol-17β en-keyword=oviduct kn-keyword=oviduct en-keyword=rho kinase kn-keyword=rho kinase en-keyword=RND3 kn-keyword=RND3 END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=30309 end-page=30326 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Self-Adaptive Framework for Deploying Machine Learning Systems Without Ground-Truth Data at Runtime en-subtitle= kn-subtitle= en-abstract= kn-abstract=In recent years, the practical application of machine learning technology has rapidly progressed, accelerating its adoption across various fields. In this context, studies into the effective operation of machine learning systems in real-world environments have become essential. In actual operational settings, the distribution of input data often changes over time, leading to a significant decline in the predictive performance of models. Additionally, the lack of ground-truth data for test data during operation can sometimes make adaptation through retraining difficult. This study proposes a framework that autonomously adapts to changes in input data distribution, even in environments where ground-truth data for test data is unavailable during operation. This framework analyzes the distribution of input data and selects the appropriate predictive model based on the state of the distribution. To ensure optimal model selection, the framework employs two complementary approaches: 1) dynamically switching between multiple pre-trained models with different feature sets according to environmental changes and 2) building ensemble models based on the distribution of the test data. These approaches enable the framework to autonomously adapt to shifts in data distribution, even in operational settings where ground-truth data is unavailable. Evaluation experiments using both simulated and real-world data assessed the predictive performance of the proposed method through metrics such as R2, RMSE, and MAE. Compared to conventional single model predictions, the proposed method consistently demonstrated higher accuracy. These results indicate that the proposed approach effectively adapts to data distribution shifts in operational environments where ground-truth data is unavailable. en-copyright= kn-copyright= en-aut-name=FurukawaKento en-aut-sei=Furukawa en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakagawaHiroyuki en-aut-sei=Nakagawa en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsuchiyaTatsuhiro en-aut-sei=Tsuchiya en-aut-mei=Tatsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Information Science and Technology, Osaka University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Information Science and Technology, Osaka University kn-affil= en-keyword=Self-adaptive systems kn-keyword=Self-adaptive systems en-keyword=frameworks kn-keyword=frameworks en-keyword=machine learning kn-keyword=machine learning END start-ver=1.4 cd-journal=joma no-vol=135 cd-vols= no-issue= article-no= start-page=103134 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Regulation of brain-specific kinases 1 and 2 (BRSK1/2) by Ca2+/calmodulin en-subtitle= kn-subtitle= en-abstract= kn-abstract=We conducted a genome-wide calmodulin (CaM) interaction screening of 462 GST-fused human protein kinases to identify novel CaM-dependent protein kinases (CaMKs). In addition to known CaMKs, including myosin light chain kinases, CaMK2γ, and death-associated kinase 2, we identified the brain-specific protein kinase 2 (BRSK2, also known as SAD-A) as a novel CaM interactant. Proximity biotinylation and CaM?sepharose chromatography assays revealed that rat BRSK isoforms (BRSK1/2) interact with CaM in a Ca2+-dependent manner in vitro. We found that CaM suppresses the activation-loop phosphorylation of BRSK1 (at Thr189) and BRSK2 (at Thr175) by liver kinase B1 (LKB1), an activating kinase, in a Ca2+-dependent manner (IC50 of ?7 ?M), thereby inhibiting BRSK activation. LKB1-catalyzed phosphorylation of the catalytic domain mutant of BRSK1 (residues 1?294) at Thr189 was suppressed by the addition of Ca2+/CaM, consistent with direct CaM binding of the kinase domain, as well as wild-type BRSK1. We confirmed that the LKB1 activity was not directly suppressed by Ca2+/CaM, supporting the hypothesis that the direct interaction of Ca2+/CaM with the kinase domain blocks the phosphorylation/activation of BRSK1/2 by LKB1. The kinase activity and PP2Cα-catalyzed dephosphorylation of LKB1-phosphorylated BRSK1 were not altered by Ca2+/CaM, although it was demonstrated to bind to Ca2+/CaM like that of unphosphorylated BRSK1. This unrecognized mechanism of BRSK1/2 regulation, involving the direct role of Ca2+/CaM binding, which inhibits phosphorylation/activation by LKB1, may open a new Ca2+ signal transduction pathway in neurons. en-copyright= kn-copyright= en-aut-name=WashidaNaoyuki en-aut-sei=Washida en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KataokaMoe en-aut-sei=Kataoka en-aut-mei=Moe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BrunAnna R. en-aut-sei=Brun en-aut-mei=Anna R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakezakiUryu en-aut-sei=Takezaki en-aut-mei=Uryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HijikawaKo en-aut-sei=Hijikawa en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamauchiHaruki en-aut-sei=Yamauchi en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OhtsukaSatomi en-aut-sei=Ohtsuka en-aut-mei=Satomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MagariMasaki en-aut-sei=Magari en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MorishitaRyo en-aut-sei=Morishita en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TokumitsuHiroshi en-aut-sei=Tokumitsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil=Department of Applied Chemistry and Biotechnology, Faculty of Engineering, Okayama University kn-affil= affil-num=3 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Applied Chemistry and Biotechnology, Faculty of Engineering, Okayama University kn-affil= affil-num=6 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=7 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=8 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=9 en-affil=CellFree Sciences Co., Ltd. kn-affil= affil-num=10 en-affil=Applied Cell Biology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=BRSK1 kn-keyword=BRSK1 en-keyword=BRSK2 kn-keyword=BRSK2 en-keyword=calmodulin kn-keyword=calmodulin en-keyword=LKB1 kn-keyword=LKB1 en-keyword=phosphorylation kn-keyword=phosphorylation en-keyword=Ca2+ kn-keyword=Ca2+ en-keyword=CaM-dependent protein kinase kn-keyword=CaM-dependent protein kinase END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=237 end-page=251 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Preliminary Consideration on the Introduction of Philosophical Thinking into Special Needs Education: A Methodological Framework Based on the Concepts of Duration, Becoming, and Diffraction kn-title=特別支援教育への哲学的思考導入についての予備的考察 持続・生成変化・回折の考え方に基づく方法的枠組みの試案 en-subtitle= kn-subtitle= en-abstract=This paper presents a theoretical and methodological examination aimed at introducing philosophical thinking into the practice of special needs education in response to contemporary challenges in the field. As its theoretical foundation, the study outlines Bergson’ s theory of memory, Deleuze and Guattari’ s philosophy of becoming, Barad’ s diffractive methodology, and Blom’ s diffractive ethnography. Building upon these theories, it proposes a methodological framework that adopts three interrelated analytical perspectives?“material-discursive practices,” “duration,” and “becoming”?for reading and interpreting educational practices. These perspectives, situated within the paradigm of post-qualitative research, make it possible to understand educational events as relational and processual phenomena rather than fixed outcomes. Future issues include the theoretical integration of the three lenses, clarification of the distinctions between diffractive methodology and diffractive ethnography, and refinement of analytical methods for connecting multiple practice episodes. kn-abstract=　本稿は，現代の特別支援教育の課題から，特別支援教育実践に哲学的思考を導入するための理論的・方法的検討を行うものである。まず，理論基盤として，ベルクソンの「記憶理論」，ドゥルーズ＆ガタリの「生成変化の哲学」，Baradの「回折的方法論」，Blomの「回折的エスノグラフィー」について概説した。そして，理論基盤を基に方法的枠組みとして，「物質−言説的実践」，「持続」，「生成変化」の三つの視点を教育実践を読み解くための相互補完的な分析視点として採用することを提案した。これらの視点は，ポスト質的研究として，出来事を関係的・過程的に捉えることを可能にするものである。今後の課題として，三つのレンズ間の理論的整理，回折的方法論と回折的エスノグラフィーの差異化，および複数の実践エピソードを接続して描くための分析手法の精緻化が挙げられた。 en-copyright= kn-copyright= en-aut-name=HAMADAYo en-aut-sei=HAMADA en-aut-mei=Yo kn-aut-name=M田曜 kn-aut-sei=M田 kn-aut-mei=曜 aut-affil-num=1 ORCID= en-aut-name=TAKANOMiyuki en-aut-sei=TAKANO en-aut-mei=Miyuki kn-aut-name=野美由紀 kn-aut-sei=野 kn-aut-mei=美由紀 aut-affil-num=2 ORCID= en-aut-name=SATOSatoru en-aut-sei=SATO en-aut-mei=Satoru kn-aut-name=佐藤曉 kn-aut-sei=佐藤 kn-aut-mei=曉 aut-affil-num=3 ORCID= affil-num=1 en-affil=Okayama Prefectural Okayama Seto Special Needs School kn-affil=岡山県立岡山瀬戸高等支援学校 affil-num=2 en-affil=Hyogo University of Teacher Education kn-affil=兵庫教育大学大学院 affil-num=3 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=特別支援教育 (special needs education) kn-keyword=特別支援教育 (special needs education) en-keyword=哲学 (philosophy) kn-keyword=哲学 (philosophy) en-keyword=分析視点 (analytical perspectives) kn-keyword=分析視点 (analytical perspectives) en-keyword=ポストヒューマニズム (posthumanism) kn-keyword=ポストヒューマニズム (posthumanism) en-keyword=質的研究 (qualitative research) kn-keyword=質的研究 (qualitative research) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=205 end-page=219 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Tier 1 Support of School-Wide Positive Behavior Support (SWPBS) in the High School Division of a Special Needs School for Students with Intellectual Disabilities: Implementation and Effects of a Campaign-Based Approach kn-title=知的障害高等特別支援学校における SWPBS 第１層支援 ―キャンペーン方式の導入とその効果― en-subtitle= kn-subtitle= en-abstract=This study examined the effects of a campaign-based intervention implemented as Tier 1 support within School-Wide Positive Behavior Support (SWPBS). It took place at a public upper secondary school for students with mild intellectual disabilities. A “Thank-You Campaign” was conducted with 24 students in one grade level. The frequency of predefined target behaviors was analyzed using AB design with follow-ups. A social validity questionnaire was also administered to six teachers of the same grade. Results showed that both the frequency of the target behaviors and the percentage of students engaging in those behaviors increased after the campaign. These increases remained above baseline levels for a certain period after the campaign ended. The intervention also demonstrated a moderate degree of social validity. These findings suggest that campaign-based approaches can be a useful form of Tier 1 support in SWPBS for students with mild intellectual disabilities at the upper secondary level. kn-abstract=　本研究は，軽度知的障害のある後期中等教育段階の公立知的障害高等特別支援学校において，SWPBS 第1層支援としてキャンペーン方式の支援を実施し，その効果検証を行った。方法としては，Ｘ学年生徒24名に対して挨拶行動の促進を狙ったキャンペーンを実施し，目標行動の生起数についてABフォローアップデザインを用いて検討した。また，Ｘ学年教員6名に対し，社会的妥当性を評価するアンケートを実施した。その結果，キャンペーンの介入直後に目標行動の生起数および目標行動に従事した生徒の割合の増加が見られ，キャンペーン終了後もベースラインと比較した増加が一定期間確認された。また，一定程度の社会的妥当性も確認できた。 en-copyright= kn-copyright= en-aut-name=TOKIMITSUHideaki en-aut-sei=TOKIMITSU en-aut-mei=Hideaki kn-aut-name=時光秀明 kn-aut-sei=時光 kn-aut-mei=秀明 aut-affil-num=1 ORCID= en-aut-name=MIYAZAKIYoshio en-aut-sei=MIYAZAKI en-aut-mei=Yoshio kn-aut-name=宮ｱ善郎 kn-aut-sei=宮ｱ kn-aut-mei=善郎 aut-affil-num=2 ORCID= en-aut-name=KOYAMAMadoka en-aut-sei=KOYAMA en-aut-mei=Madoka kn-aut-name=小山円 kn-aut-sei=小山 kn-aut-mei=円 aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Education (Professional Degree Course), Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=3 en-affil=Kurashiki Kotoura Special Needs Seni or High School, Okayama Prefecture kn-affil=岡山県立倉敷琴浦高等支援学校 en-keyword=高等部 (High school division) kn-keyword=高等部 (High school division) en-keyword=軽度知的障害 (Mild intellectual disabilities) kn-keyword=軽度知的障害 (Mild intellectual disabilities) en-keyword=SWPBS（学校規模ポジティブ行動支援）(School-Wide Positive Behavior Support (SWPBS)) kn-keyword=SWPBS（学校規模ポジティブ行動支援）(School-Wide Positive Behavior Support (SWPBS)) en-keyword=第1層支援 (Tier 1 support) kn-keyword=第1層支援 (Tier 1 support) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=167 end-page=180 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Study on Developing High School Civics Lesson Plan Aimed at Improving Understanding of Constitutionalism: Depending on “We the People” of the Center for Civic Education kn-title=立憲主義に対する認識の改善を目指した高等学校公民科の授業開発研究 ―米国公民教育センター開発『我ら合衆国人民』を手がかりにして― en-subtitle= kn-subtitle= en-abstract=This study aims to develop practicable lessons for high school civics classes that foster an understanding of constitutionalism as the foundation for grasping the Constitution. Traditional Japanese social studies education focused on understanding the Constitution's fundamental principles?popular sovereignty, respect for basic human rights, and pacifism. But, recently, the concept of constitutionalism has gained attention as a means to help students understand what a constitution fundamentally is, and it is now described in textbooks. This study proposes a lesson plan designed to help students appropriately grasp the concept of constitutionalism. In making the lesson plan, we referenced the long-used “We the People” program developed by the Center for Civic Education in U.S. We adapted materials originally created based on the historical context of the United States to fit the Japanese context, utilizing parts of this program. kn-abstract=　本研究は、憲法理解の基本としての立憲主義に対する認識形成を目標とする、高等学校公民科で実践可能な授業の開発を目指したものである。従来の日本の社会科教育においては、憲法理解は日本国憲法の基本原則である国民主権、基本的人権の尊重、平和主義の理解を基本としていたが、近年、そもそも憲法とは何かを理解させるために、立憲主義の概念が注目されるようになり、教科書にも記述されている。本研究は、そのような立憲主義という概念について生徒に適切に理解させることを目指した授業の提案をしようとするものである。授業計画作成にあたっては、米国の公民教育センターが開発し、長年活用されている『我ら合衆国人民（原題 We the People）』を参照し、その一部を活用し、米国の歴史的背景に基づいて作られた教材を、日本の文脈にそって改変した。 en-copyright= kn-copyright= en-aut-name=KUWABARAToshinori en-aut-sei=KUWABARA en-aut-mei=Toshinori kn-aut-name=桑原敏典 kn-aut-sei=桑原 kn-aut-mei=敏典 aut-affil-num=1 ORCID= en-aut-name=MIYAMOTOAyuha en-aut-sei=MIYAMOTO en-aut-mei=Ayuha kn-aut-name=宮本あゆは kn-aut-sei=宮本 kn-aut-mei=あゆは aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=2 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil=岡山大学大学院社会文化学研究科社会文化学専攻 en-keyword=授業開発研究 (Lesson Development Research) kn-keyword=授業開発研究 (Lesson Development Research) en-keyword=公民科 (Civic Education) kn-keyword=公民科 (Civic Education) en-keyword=憲法学習 (Constitutional Studies) kn-keyword=憲法学習 (Constitutional Studies) en-keyword=立憲主義 (Constitutionalism) kn-keyword=立憲主義 (Constitutionalism) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=107 end-page=121 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Developing Lesson Plan for Global Citizenship Education in Junior High School Music Education through Japan-Korea Music Cultural Exchange: Based on Research Findings from an Internship at APCEIU kn-title=日韓の音楽文化交流を通した中学校音楽科におけるグローバル・シティズンシップ教育の構想 ―APCEIUでのインターンシップにおける調査の成果に基づいて― en-subtitle= kn-subtitle= en-abstract=This paper proposes a Global Citizenship Education program for junior high school music classes. The program aims to promote mutual understanding by having students examine the musical cultures of Japan and Korea, identifying their cultural differences and commonalities. In designing the program, author Konishi drew upon methods of GCED being implemented in Korea, identified through field research conducted during a roughly one-month internship at APCEIU (Asia-Pacific Centre of Education for International Understanding) in Seoul, Korea. The developed program focused on percussion instruments from both Japan and Korea. By comparing these instruments, students identified cultural differences between the two countries. The program then aimed to deepen students' understanding of cultural diversity and the unique value of each country's culture, while also helping them recognize the historical background underlying each nation's musical culture and accept these differences. kn-abstract=　本論文は、中学校音楽科において、日本と韓国の音楽文化を取り上げて、互いの文化の違いや共通性を捉えさせたうえで相互理解を促進する、グルーバル・シティズンシップ教育（以下、GCED と表記）プログラムを構想しようとするものである。プログラムの構想の際には、筆者である小西が、韓国のソウルのAPCEIU（アジア太平洋国際理解教育センター）で行なった約一か月間のインターンシップの間の実地調査で把握した、韓国で展開されているGCED の方法を参考にした。開発プログラムでは、日韓両国の打楽器を取り上げて、その比較から互いの文化の違いを捉えさせたうえで、違いを受け入れながら、それぞれの国の音楽文化の根底にある歴史的背景に気づかせたうえで、文化の多様性や両国の文化の固有の価値に対する理解を深めることを目指した。 en-copyright= kn-copyright= en-aut-name=KONISHIHikari en-aut-sei=KONISHI en-aut-mei=Hikari kn-aut-name=小西光 kn-aut-sei=小西 kn-aut-mei=光 aut-affil-num=1 ORCID= en-aut-name=KUWABARAToshinori en-aut-sei=KUWABARA en-aut-mei=Toshinori kn-aut-name=桑原敏典 kn-aut-sei=桑原 kn-aut-mei=敏典 aut-affil-num=2 ORCID= en-aut-name=KONISHIYumi en-aut-sei=KONISHI en-aut-mei=Yumi kn-aut-name=小西裕美 kn-aut-sei=小西 kn-aut-mei=裕美 aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Education kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil=Faculty of Education kn-affil=岡山大学学術研究院教育学域 affil-num=3 en-affil=Graduate School of Education kn-affil=岡山大学大学院教育学研究科 en-keyword=グローバル・シティズンシップ教育 (Global Citizenship Education) kn-keyword=グローバル・シティズンシップ教育 (Global Citizenship Education) en-keyword=音楽科 (Music Education) kn-keyword=音楽科 (Music Education) en-keyword=異文化理解 (Cross-Cultural Understanding) kn-keyword=異文化理解 (Cross-Cultural Understanding) en-keyword=授業開発 (Lesson Development) kn-keyword=授業開発 (Lesson Development) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=91 end-page=105 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Practical Research on Nurturing the Next Generation of Classical Japanese Instrument Music that Connects the Local and the Global Community (3) .

(2025). In the lesson practice, details of the climate and seasonal cycle around Germany were firstly explained and the German lied “Im Fr?hling” (In spring) composed by F. Schubert was appreciated, paying attention to how the scenes and emotions expressed by the lyrics “all summer long” in the 3rd verse of this song might differ whether we imagine the climate around Germany or that around Japan. It seems that the present activity provided an opportunity for the students to perceive the climate environments and seasonal feelings quite different from those familiar to them . However, how to explore the appreciation activities that focus also on the musical expression itself of that song is an interesting remaining problem, in order for the students to capture the summer scenery and emotions which Schubert himself imagined. kn-abstract=　「異質な他者」への出会いを促す授業例の更なる蓄積のため，ドイツ付近の「夏」の気候と季節感に注目した教科横断的な授業を大学で実践した。授業では，ドイツ付近の気候と季節サイクルの中での「夏」の特徴を把握すると共に，シューベルトの歌曲《春に》を鑑賞した。《春に》の3 番の「夏の間じゅう，ずっと」という歌詞で歌われている情景や情感が，ドイツ付近と日本付近を想定した場合にどう違い得るか，に関する受講生の記述を分析した。その結果，日本の夏の高温多湿な環境からは原詩の情感そのものが成立し難いと感じた学生もいるなど，本実践は，自分たちの「当たり前」とは異なる気候や季節感にも目を向ける機会になり得たといえる。一方，日本とはかなり違う気候背景の中でシューベルトが思い描いたであろう情景・心情に授業で深く迫るための，音楽表現自体への踏み込み方についても，今後検討する必要性が示唆された。 en-copyright= kn-copyright= en-aut-name=KATOKuranoshin en-aut-sei=KATO en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=1 ORCID= en-aut-name=NAGAOKAIsao en-aut-sei=NAGAOKA en-aut-mei=Isao kn-aut-name=長岡功 kn-aut-sei=長岡 kn-aut-mei=功 aut-affil-num=2 ORCID= en-aut-name=KATOHaruko en-aut-sei=KATO en-aut-mei=Haruko kn-aut-name=加藤晴子 kn-aut-sei=加藤 kn-aut-mei=晴子 aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=3 en-affil=Faculty of Education, Gufu Shotoku Gakuen University (Former affiliation) kn-affil=元　岐阜聖徳学園大学教育学部 en-keyword=気候と音楽 kn-keyword=気候と音楽 en-keyword=ドイツ付近の夏の気候と季節感 kn-keyword=ドイツ付近の夏の気候と季節感 en-keyword=気候と文化理解の学際的ESD教師教育 kn-keyword=気候と文化理解の学際的ESD教師教育 en-keyword=異質な他者への理解 kn-keyword=異質な他者への理解 END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=15 end-page=29 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Critical Reading Instruction of Expository Text that Promotes Reflecting: Practice for First-year Student at High School kn-title=説明的文章の指導における「内省」を促す批判的読み ―高等学校１年生を対象として― en-subtitle= kn-subtitle= en-abstract=　Critical reading is an essential skill at present time and is included in government guidelines for teaching. Although recent research on teaching critical reading has been conducted, there have been criticisms that lack of consideration of content value and understanding context within society. There are also calls for critical reading that focuses on the perspective of “reflect” . Therefore, this paper developed a lesson that encourages students not only critically read the text, but also critically consider (reflect on) their own ideas. As a measure to achieve this, incorporated activities such as comparing two teaching materials that contained multiple social perceptions, exchanging opinions from opposing perspectives, writing an evaluation of the materials, and having the students themselves evaluate their own writing (their own reading). Analysis of the students’ writings shows that, while some students didn’ t reach conscious reflection, about 60% of students’ writings showed changes. And then it suggests that the methods used were effective. kn-abstract=　批判的読みは，現代では欠かせない能力であり，学習指導要領にも明記されている。近年，批判的読みの指導に関する研究がなされているものの，内容的な価値の検討や社会的な文脈のなかで捉えることが希薄だとする指摘や，「反省性」という観点に着目した批判的読みを求める声もある。そこで，本稿では，文章そのものを批判的に読むだけでなく，自身の持っている考えをも批判的に捉える（内省する）ことを促す授業を開発した。その手立てとして，複数の社会認識が存在する二つの教材の読み比べたうえで，対立する立場からの意見交換を行うことや，教材に対する評価の記述，その記述（自己の読み）を学習者自身が評価するといった活動を取り入れた。学習者の記述の分析からは，意識的な内省に至らなかった学習者も見受けられたものの，約６割の学習者の記述には変容が見られ，用いた手立ては効果があったと推測できることを指摘した。 en-copyright= kn-copyright= en-aut-name=SAISHOYumi en-aut-sei=SAISHO en-aut-mei=Yumi kn-aut-name=最相有未 kn-aut-sei=最相 kn-aut-mei=有未 aut-affil-num=1 ORCID= en-aut-name=IKEDAMasafumi en-aut-sei=IKEDA en-aut-mei=Masafumi kn-aut-name=池田匡史 kn-aut-sei=池田 kn-aut-mei=匡史 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education (Professional Degree Corse), Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=反省性 (reflectiveness) kn-keyword=反省性 (reflectiveness) en-keyword=情意的性向 (affective disposition) kn-keyword=情意的性向 (affective disposition) en-keyword=複数テクスト (multiple texts) kn-keyword=複数テクスト (multiple texts) en-keyword=「現代の国語」 (“Contemporary Japanese Language”) kn-keyword=「現代の国語」 (“Contemporary Japanese Language”) en-keyword=生物多様性 (biodiversity) kn-keyword=生物多様性 (biodiversity) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=1 end-page=13 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Preschool Teachers’ Strategies and Practical Challenges in Supporting the School Enrollment of Foreign Children kn-title=外国人幼児の就学支援における保育士の工夫と実践的課題 en-subtitle= kn-subtitle= en-abstract=This study aimed to clarify the specific practices and challenges faced by preschool teachers in supporting foreign children at the time of school enrollment. Semi-structured interviews were conducted with two preschool teachers who had experience in supporting foreign children, and qualitative analysis using SCAT was applied to organize the support provided to both children and their parents. The results revealed that, in terms of language support, teachers utilized visual aids and simplified Japanese, while in cultural support they sought to balance family culture with the culture of the preschool. Regarding developmental support, the importance of fostering non-cognitive skills and collaborating with medical institutions was highlighted. In parent support, participatory involvement and careful explanations were practiced; however, challenges remained in providing institutional information and establishing collaboration with local governments. Based on these findings, it is necessary to establish a regional collaborative system that can provide institutional support for families with multicultural backgrounds, standardize the provision of information, and build practical mechanisms to connect with Japanese language education resources, so that support does not rely solely on the individual efforts of preschool teachers. kn-abstract=　本研究は，外国人幼児が就学期に直面する困難に対応するため，保育士が行っている具体的な保育実践における支援の工夫と課題を明らかにすることを目的とした。外国人幼児の支援経験を有する保育士2 名に半構造化インタビューを行い，SCAT を用いた質的分析により，幼児および保護者への支援内容を整理した。その結果，言語面では視覚的支援ややさしい日本語を活用し，文化面では家庭文化と日本の園文化の調整が行われていた。発達支援においては，非認知的スキルの育成や医療機関との連携の必要性が指摘された。保護者支援では，参加型の関わりや丁寧な説明が実践されていたが，制度情報の提供や行政との連携には課題が残された。これらの結果を踏まえ，今後は保育士の個別的努力に依存しないためにも，多文化背景をもつ家庭への支援を制度的に支える地域連携体制の整備や，情報提供の標準化，日本語教育資源との接続を図る実践的仕組みの構築が求められる。 en-copyright= kn-copyright= en-aut-name=CHENYiwen en-aut-sei=CHEN en-aut-mei=Yiwen kn-aut-name=陳依文 kn-aut-sei=陳 kn-aut-mei=依文 aut-affil-num=1 ORCID= en-aut-name=YANAGISAWAKazuki en-aut-sei=YANAGISAWA en-aut-mei=Kazuki kn-aut-name=柳澤佳月 kn-aut-sei=柳澤 kn-aut-mei=佳月 aut-affil-num=2 ORCID= en-aut-name=REN Xinyu en-aut-sei=REN en-aut-mei= Xinyu kn-aut-name=任芯于 kn-aut-sei=任 kn-aut-mei=芯于 aut-affil-num=3 ORCID= en-aut-name=YOSHITOSHIMunehisa en-aut-sei=YOSHITOSHI en-aut-mei=Munehisa kn-aut-name=吉利宗久 kn-aut-sei=吉利 kn-aut-mei=宗久 aut-affil-num=4 ORCID= affil-num=1 en-affil=The Joint Graduate School (Ph.D. Program) in Science of School Education, Hyogo University of Teacher, Hyogo University of Teacher Education kn-affil=兵庫教育大学大学院連合学校教育学研究科博士課程 affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=3 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=4 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=外国人幼児 (foreign preschool children) kn-keyword=外国人幼児 (foreign preschool children) en-keyword=就学 (school enrollment) kn-keyword=就学 (school enrollment) en-keyword=保育士 (preschool teachers) kn-keyword=保育士 (preschool teachers) END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=3 article-no= start-page=55 end-page=59 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260315 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Low Temperature Formation of Dense Yttria-Stabilized Zirconia Layer Using Hot Isostatic Pressing kn-title=熱間静水圧加圧法を用いたイットリア安定化ジルコニア緻密層の低温形成 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The sintering conditions using hot isostatic press (HIP) of yttria-stabilized zirconia (YSZ) were investigated to obtain a dense YSZ layer at low sintering temperature such as 1000°C for an electrolyte of metal-supported solid oxide fuel cell. It was found that a dense YSZ pellet with relative density of 93% could be obtained under a sintering condition of 1000°C-10 hours with HIP in 195 MPa. On the other hand, in X-ray diffraction analysis of the dense YSZ pellet, peaks of the monoclinic phase were slightly detected in addition to peaks of the cubic phase. From energy dispersive X-ray spectroscopy analysis, a small amount of boron was detected in the dense YSZ pellet. It is considered that the YSZ crystalline phase transformation of cubic to monoclinic phase was occurred by the boron diffusion from the diffusion barrier coating of metal foil capsule used for the HIP. en-copyright= kn-copyright= en-aut-name=MANABEKyohei en-aut-sei=MANABE en-aut-mei=Kyohei kn-aut-name=真鍋享平 kn-aut-sei=真鍋 kn-aut-mei=享平 aut-affil-num=1 ORCID= en-aut-name=ECHIGOMitsuaki en-aut-sei=ECHIGO en-aut-mei=Mitsuaki kn-aut-name=越後満秋 kn-aut-sei=越後 kn-aut-mei=満秋 aut-affil-num=2 ORCID= en-aut-name=KISHIMOTOAkira en-aut-sei=KISHIMOTO en-aut-mei=Akira kn-aut-name=岸本昭 kn-aut-sei=岸本 kn-aut-mei=昭 aut-affil-num=3 ORCID= affil-num=1 en-affil=Osaka Gas Co.

In addition to primary symptoms, including oral and genital ulcers, ocular involvement, and skin lesions, BD can also affect various organs. However, renal involvement, particularly in tubulointerstitial nephritis, has rarely been described. Herein, a rare case of acute tubulointerstitial nephritis in a patient clinically diagnosed with BD is reported. The renal lesion presented with other symptoms of BD and fever, and was considered to be BD-related due to the presence of neutrophilic infiltration and its responsiveness to BD-directed therapy. Alterations in T-helper (Th) 1, Th2, and Th17 cytokine profiles are associated with BD activity. Interleukin (IL)-17 plays a central role in neutrophil activation, and recent studies have demonstrated a strong correlation between IL-17A levels and BD activity. In the present case, elevated serum IL-17A levels and infiltration of IL-17A-positive cells into the renal tissue reflected an active phase of BD and a BD-associated renal lesion. en-copyright= kn-copyright= en-aut-name=UchidaNaruhiko en-aut-sei=Uchida en-aut-mei=Naruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaKeiko en-aut-sei=Tanaka en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KubotaNatsuki en-aut-sei=Kubota en-aut-mei=Natsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatsuyamaTakayuki en-aut-sei=Katsuyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanabeKatsuyuki en-aut-sei=Tanabe en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UchidaHaruhito A. en-aut-sei=Uchida en-aut-mei=Haruhito A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Tubulointerstitial nephritis kn-keyword=Tubulointerstitial nephritis en-keyword=Beh?et’s disease kn-keyword=Beh?et’s disease en-keyword=Neutrophils kn-keyword=Neutrophils en-keyword=Interleukin-17 kn-keyword=Interleukin-17 en-keyword=T-helper (Th) 1/Th2/Th17 cytokines kn-keyword=T-helper (Th) 1/Th2/Th17 cytokines END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=3 article-no= start-page=e202500639 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=PPy‐Coated Wire Actuators for the Micromechanostimulation of Cells: Fabrication and Characterization en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cellular mechanotransduction signals play a crucial role in physiological and pathological conditions, including skeletal disorders. Although various systems exist to mechanically stimulate cultured cells, most are constrained by incubator incompatibility, limited physiological relevance, nonuniform stimulation, or complexity. The objective of this article is to develop and validate a compact, incubator-compatible tool capable of delivering localized and physiologically relevant mechanical stimulation to small cell populations. Here, we introduce a polypyrrole-based wire-shaped microactuator designed to induce localized mechanical stress to adjacent cells. These wire-shaped microactuators are biocompatible, easy-to-use, and compact for use within standard in vitro cell culture systems. Using a noncontact optical method, we characterize the actuation of polypyrrole-coated wires in an aqueous NaDBS electrolyte, showing radial expansion of 1.5?8??m depending on the deposited polypyrrole film thickness, comparable to cellular dimensions. Next, the actuation is confirmed to be robust and stable to use in cell culture media at physiological temperature. To evaluate biological relevance, osteoblastic KUSA-A1 cells are mechanically stimulated inside the incubator and transcriptomic changes are assessed. Mechanical stimulation resulted in upregulation of genes previously associated with mechanotransduction, including Fos and Fosb. Additionally, several uncharacterized long noncoding RNAs are differentially expressed, suggesting potential novel players in the mechanotransduction pathway. en-copyright= kn-copyright= en-aut-name=Ortega‐SantosAmaia B. en-aut-sei=Ortega‐Santos en-aut-mei=Amaia B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayanoSatoru en-aut-sei=Hayano en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaraEmilio Satoshi en-aut-sei=Hara en-aut-mei=Emilio Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Mart?nezJose G. en-aut-sei=Mart?nez en-aut-mei=Jose G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KamiokaHiroshi en-aut-sei=Kamioka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=JagerEdwin W.

WGCNA enables the identification of gene clusters (modules) exhibiting correlated expression patterns, the association of these modules with traits, and the exploration of candidate biomarker genes by focusing on hub genes within the modules. WGCNA has been successfully applied in diverse biological contexts. However, conventional algorithms manifest three principal limitations: the assumption of scale-free topology, the requirement for parameter tuning, and the neglect of regression line slopes. These limitations are addressed by SGCRNA. SGCRNA provides Julia functions for the analysis of co-expression networks derived from various types of biological data, such as gene expression data.

A common method used to protect against these kinds of threats is the use of intrusion detection systems (IDS). However, the agricultural environment is often changing and has limited resources, which makes cybersecurity challenging. Several available IDS tools are not designed to work properly in places with few resources, intermittent access, and unpredictable network conditions. This paper investigates the performance of Zeek, an open-source IDS, in identifying potential threats in agricultural IoT networks. We performed both offline and real-time experiments: offline analysis used pcap files from the Stratosphere Laboratory dataset, and real-time evaluation involved simulated live attack scenarios, focusing on unauthorized access attempts and distributed denial-of-service (DDoS) attacks. Zeek's performance was assessed based on CPU and memory utilization, as well as quality of service (QoS) metrics. From the experimental results, we found that Zeek was quite effective in protecting agricultural IoT networks against typical threats. Memory usage remained stable around 5% during offline analysis and under 20% during active attacks. However, CPU usage was more volatile, peaking at 120% during DDoS events. In terms of QoS, the system maintained a good throughput (1,375 kbits/s) with minimal packet loss (0.000186%). Among the attack types that we tested, brute force attacks, which represent attempts at unauthorized access, had the strongest effect on network performance, increasing delay to 2.159 ms and jitter to 0.793 ms. It seems clear that a heavier traffic load during such attacks can interfere with QoS. On the basis of our observation, we recommend practical deployment strategies for agricultural IoT systems that take these limitations into consideration, aiming to keep networks both secure and efficient under pressure. en-copyright= kn-copyright= en-aut-name=HudaSamsul en-aut-sei=Huda en-aut-mei=Samsul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MusthafaMuhammad Bisri en-aut-sei=Musthafa en-aut-mei=Muhammad Bisri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShamimS.

The slow-freezing (SLF) method, currently the standard for PBMC cryopreservation, involves extended storage at ?80°C before transfer to liquid nitrogen. Delays in this transfer, such as overnight or weekend holds, risk a gradual decline in cell viability. Additionally, variability in freezing duration can lead to inconsistent cell quality, emphasizing the need for an alternative freezing method that allows for more timely transfer to liquid nitrogen. This study is aimed at clarifying whether the method of using a freezer with an applied electromagnetic field (EMF) is superior to the currently used standard SLF method for PBMC cryopreservation. A comparison of the number of viable cells, cell viability, and cell activity showed that the EMF method was equivalent to the SLF method. However, the shortest time required for freezing was significantly shorter with the EMF method than the SLF method (0.25 vs. 3?h), allowing for earlier transfer of PBMC to liquid nitrogen. This demonstrates that the EMF method offers an advantage in operational efficiency, particularly for facilities that routinely process and store PBMCs, such as biobanks and other storage-focused departments. en-copyright= kn-copyright= en-aut-name=MatsubaraTakehiro en-aut-sei=Matsubara en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakagiMina en-aut-sei=Takagi en-aut-mei=Mina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UwaboTakahiro en-aut-sei=Uwabo en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SohJunichi en-aut-sei=Soh en-aut-mei=Junichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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= en-aut-name=MoritaMizuki en-aut-sei=Morita en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Okayama University Hospital Biobank kn-affil= affil-num=2 en-affil=Faculty of Health Sciences, Okayama University Medical School kn-affil= affil-num=3 en-affil=Department of Biorepository Research and Networking, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Thoracic Surgery, Osaka Metropolitan University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Okayama University Hospital Biobank kn-affil= affil-num=6 en-affil=Okayama University Hospital Biobank kn-affil= END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=2 article-no= start-page=110 end-page=118 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Trend of adjusted antenatal care visits on pregnant women and neonatal during the COVID-19 pandemic: Findings from a three districts survey in 2021 en-subtitle= kn-subtitle= en-abstract=Upaya pengembangan kesehatan berkelanjutan di tengah wabah penyakit menular seperti COVID-19 memerlukan sistem kesehatan ibu yang tangguh.

With cases rising globally and across Asia, Indonesia faces significant disruptions in essential services. A critical research gap exist in utilizing adjusted time-series analysis to isolated pandemic impact from seasonal variation in urban Indonesia. This study evaluates trends in antenatal care (ANC) visits (January 2019?December 2020) at three Community Health Centres in Makassar: Bara-Baraya, Jongaya and Batua using Interrupted Time Series (ITS) analysis. Findings reveal a significant decline in visits during the second and third quarters of 2020, primarily due to transmission fears. We suggest integration of telemedicine and home visits to maintain continuity of care. Although focused on urban Makassar, these results are an important reference for health and offer applicable solutions for other developing countries facing resource constraints. This study emphasizes the need for inclusive prevention strategies to protect maternal health in urban and rural areas in low- to middle-income countries during systemic health crises. en-copyright= kn-copyright= en-aut-name=IbrahimJuliani en-aut-sei=Ibrahim en-aut-mei=Juliani kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakahataYoko en-aut-sei=Takahata en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IbrahimSukaeni en-aut-sei=Ibrahim en-aut-mei=Sukaeni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Departement of Public Health, Faculty of Medicine and Health Science, Universitas Muhammadiyah Makassar kn-affil= affil-num=2 en-affil=Nursing of Department, Graduate School of Health Science, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Medicine, Bosowa University kn-affil= en-keyword=antenatal care kn-keyword=antenatal care en-keyword=covid-19 kn-keyword=covid-19 en-keyword=interrupted time series kn-keyword=interrupted time series en-keyword=maternal health kn-keyword=maternal health en-keyword=neonatal birth kn-keyword=neonatal birth END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=9 article-no= start-page=14570 end-page=14577 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Water-Resistant Antibacterial Coatings Using Cetylpyridinium Chloride - Graphene Oxide Composites en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hospital-acquired infections remain a persistent threat in healthcare settings, especially with the increasing number of elderly and immunocompromised patients. In situations where the use of disposable materials is difficult, durable antibacterial surface coatings are essential. In this study, we report the structural characterization of cetylpyridinium chloride-graphene oxide (CPC?GO) hybrid materials and the sustainability of their antibacterial effects, aiming at washable antibacterial coatings for medical applications. Graphene oxide (GO) has a large surface area and numerous functional groups, while cetylpyridinium chloride (CPC) is a quaternary ammonium compound with well-documented antibacterial activity. We hypothesized that the stable incorporation of CPC through the functional groups of GO could improve surface retention and provide long-term antibacterial performance. The structural properties of the CPC?GO composites were characterized by UV?vis spectroscopy, X-ray diffraction, thermogravimetric analysis, scanning electron microscopy, and atomic force microscopy. These analyses confirmed the formation of a complex through ionic bonds and the maintenance of a planar composite structure. The antibacterial performance of the CPC?GO coatings was examined using representative bacteria. Notably, the CPC?GO coatings maintained their antibacterial activity significantly better than the negative controls even after multiple washings. The excellent surface retention of the CPC?GO composite suggests its potential as a next-generation antibacterial coating for areas where disinfection and sterilization are impossible, such as the interior of complex medical devices. This study suggests a strategy to extend the efficacy of existing antibacterial agents through the application of nanomaterials. Future studies will focus on the controlled release, long-term stability, and biocompatibility of CPC to realize clinical applications. en-copyright= kn-copyright= en-aut-name=OkuboKeisuke en-aut-sei=Okubo en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KanoGen en-aut-sei=Kano en-aut-mei=Gen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KomodaMasato en-aut-sei=Komoda en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Periodontics and Endodontics, Field of Medical Development, 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=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathophysiology - Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Department of Pathophysiology - Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=1 article-no= start-page=33 end-page=44 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Large-scale rainfall characteristics at the heavy rainfall event around the western Japan during 5?7 July 2018 kn-title=2018年7月5日?7日の西日本豪雨における広域降水特性 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　Large-scale rainfall characteristics at the heavy rainfall event around the western Japan for 5?7 July 2018 were analyzed with use of the 10-mimute precipitation data at the surface meteorological observation stations of the Japan Meteorological Agency, and so on. In this case, the area with 3 days total precipitation of near or more than 300 mm was distributed widely from northern Kyushu to Shiga and Fukui Prefectures. As in the many heavy rainfall events around Kyushu District in the mature stage of the Baiu season, contribution of the intense rainfall with more than 4 mm/10-minute (24 mm/h) attained about one third of the areal mean total precipitation. However, it is noted that the "not so intense rain" with less than 2 mm/10-minute (12 mm/h) also contributed to about one third of the huge total precipitation in the wide area. In short, this case could be characterized by the mixture of the western Japan type heavy rainfall event and the eastern Japan type one. en-copyright= kn-copyright= en-aut-name=KATOKuranoshin en-aut-sei=KATO en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=1 ORCID= en-aut-name=MATSUMOTOKengo en-aut-sei=MATSUMOTO en-aut-mei=Kengo kn-aut-name=松本健吾 kn-aut-sei=松本 kn-aut-mei=健吾 aut-affil-num=2 ORCID= en-aut-name=OTANIKazuo en-aut-sei=OTANI en-aut-mei=Kazuo kn-aut-name=大谷和男 kn-aut-sei=大谷 kn-aut-mei=和男 aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域（理科） affil-num=2 en-affil=Okayama Gakugeikan High School kn-affil=岡山学芸館高等学校 affil-num=3 en-affil=TV Setouchi Broadcasting Co., LTD. kn-affil=テレビせとうち(株) en-keyword=western Japan heavy rainfall in July 2018 kn-keyword=western Japan heavy rainfall in July 2018 en-keyword=10-minute precipitation data kn-keyword=10-minute precipitation data en-keyword=east-west difference of the Baiu precipitation kn-keyword=east-west difference of the Baiu precipitation END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=1 article-no= start-page=21 end-page=31 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A trial of lesson practice at the university on the variety of heavy rainfall characteristics based on the 10-minute precipitation data toward promoting the meteorological disaster prevention literacy kn-title=10分間降水量から大雨の特徴の多様性を捉える大学での授業の試み（防災気象リテラシー育成へ向けて） en-subtitle= kn-subtitle= en-abstract= kn-abstract=　In the disaster prevention education on the heavy rainfall around Japan, it is also important to promote the meteorological literacy on the seasonal and regional differences of their rainfall characteristics such as the convective rain or stratiform rain, together with their total amount of precipitation and their occurrence frequency. As the first step toward the above purpose, the present study made a lesson practice for the university students by utilizing the 10-minute precipitation data for the four heavy rainfall events, in which the types of the heavy rainfall (although all the cases examined in the lesson are relating to the deep convective clouds) are rather different from each other, such as the differences of the rainfall intensity at the peak time, short-period variation of the rainfall intensity and the persistency of the rainfall including the "not so intense rainfall". The reports by the students seem to perceive the different features among these events briefly, but the students' attention to how long the intense rainfall with short-period variation or "not so intense rainfall" lasted was not so sufficient. en-copyright= kn-copyright= en-aut-name=KATOKuranoshin en-aut-sei=KATO en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=1 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域（理科） en-keyword=disaster prevention education kn-keyword=disaster prevention education en-keyword=variety of the heavy rainfall characteristics kn-keyword=variety of the heavy rainfall characteristics en-keyword=meteorological disaster prevention literacy kn-keyword=meteorological disaster prevention literacy en-keyword=use of the 10-minute precipitation data kn-keyword=use of the 10-minute precipitation data END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=1 article-no= start-page=1 end-page=7 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Microtremor exploration in Kojima Bay area, Okayama Plain kn-title=岡山平野児島湾岸部での微動アレイ探査 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　This report describes microtremor array observations conducted at two sites for deep exploration and three sites for shallow exploration around Kojima Bay area in the southern Okayama Plain. Based on these records, the ground velocity structures were estimated. The results yielded solutions indicating the depth of the top of the seismic base layer (equivalent to 3 km/s layer) ranges from 140 to 300 m, while the depth of the top of the engineering basement layer (equivalent to 0.6 km/s layer) is approximately about 13?14 m. The shallow exploration results also suggested the possible presence of an inversion layer.

A mechanosensitive ion channel, PIEZO1, is involved in various musculoskeletal tissues, but its role in the annulus fibrosus (AF) remains unclear. This study aimed to elucidate the function of PIEZO1 in AF cells under mechanical stimulation.
Methods: Primary rat AF cells were subjected to cyclic tensile strain (CTS) at low (2%) and high (12%) strain levels to investigate strain-dependent effects on osteogenic gene expression. We evaluated the effects of Piezo1, Piezo2, and Trpv4 knockdown by RNA interference to identify the upstream mechanotransducer. Furthermore, PIEZO1 was activated using the agonist Yoda1, followed by RNA-sequencing analysis and evaluation of its effects on BMP2-induced osteogenesis in rat AF cells. We also examined the effects of Yoda1 in primary human AF cells.
Results: Low-strain CTS significantly suppressed osteogenic marker expression, which was not observed with high strain. Piezo1 knockdown reversed this suppression, whereas Piezo2 and Trpv4 had no effect. Piezo1 activation by Yoda1 produced similar anti-osteogenic effects in both rat and human AF cells. RNA sequencing revealed the enrichment of ossification and calcineurin signaling pathways in rat cells. Furthermore, Piezo1 activation inhibited BMP2-induced osteogenesis and nuclear translocation of p-Smad1/5/9.
Conclusions: Piezo1 maintains AF cell homeostasis under mechanical stress by suppressing osteogenic changes via calcineurin-mediated inhibition of BMP signaling, which may represent a novel therapeutic target for IVDD. en-copyright= kn-copyright= en-aut-name=ShitozawaHisakazu en-aut-sei=Shitozawa en-aut-mei=Hisakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamichiRyo en-aut-sei=Nakamichi en-aut-mei=Ryo 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=UedaMasataka en-aut-sei=Ueda en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SaitoTaichi en-aut-sei=Saito en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 ORCID= en-aut-name=TakatoriRyo en-aut-sei=Takatori en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamashitaKazutaka en-aut-sei=Yamashita en-aut-mei=Kazutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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 Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=annulus fibrosus kn-keyword=annulus fibrosus en-keyword=calcification kn-keyword=calcification en-keyword=ossification kn-keyword=ossification en-keyword=PIEZO1 kn-keyword=PIEZO1 END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=3 article-no= start-page=93 end-page=109 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Environmental Conservation Costs and Operational Efficiency: Evidence from Japanese Manufacturing Firms en-subtitle= kn-subtitle= en-abstract= kn-abstract=　This study investigates whether environmental conservation costs (ECC) support the operational effectiveness and financial stability of Japanese manufacturing firms. Using a balanced panel of 128 non-financial companies listed on the Tokyo Stock Exchange from 2010 to 2022, we manually collected firm-level ECC data based on the Ministry of the Environment, Japan's guidelines from sustainability reports and matched them with financial data from Compustat Global/S&P Capital IQ. Applying pooled ordinary least squares regression with firm-level clustered standard errors and winsorized variables, we examine two aspects of performance as measures of operating efficiency and profitability: asset turnover and profit margin. The results show that ECC is positively associated with asset turnover and profit margin, and that the effect is stronger in more profitable companies, substantiating the Resource-Based View that green practices generate competitiveness. These findings contribute to sustainability finance research by going beyond perceptual measures of environmental, social, and governance ratings, and measuring actual firm-level spending on environmental activities, thereby providing more nuanced insights into how environmental practices translate into actual financial performance. This study offers clear managerial and policy implications by showing that transparent environmental conservation costs improve disclosure quality and serve as a measure of improved efficiency and profitability. en-copyright= kn-copyright= en-aut-name=NazirYusra en-aut-sei=Nazir en-aut-mei=Yusra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TennojiyaTatsumasa en-aut-sei=Tennojiya en-aut-mei=Tatsumasa kn-aut-name=天王寺谷達将 kn-aut-sei=天王寺谷 kn-aut-mei=達将 aut-affil-num=2 ORCID= affil-num=1 en-affil=Doctoral student at Graduate school of humanities and social sciences, Okayama University kn-affil= affil-num=2 en-affil=Faculty of humanities and social sciences, Okayama University kn-affil= en-keyword=Environmental Accounting kn-keyword=Environmental Accounting en-keyword=Environmental Conservation Cost, Operating Efficiency kn-keyword=Environmental Conservation Cost, Operating Efficiency en-keyword=Profitability kn-keyword=Profitability en-keyword=Asset Turnover kn-keyword=Asset Turnover en-keyword=Sustainability kn-keyword=Sustainability en-keyword=Japanese Manufacturing Companies kn-keyword=Japanese Manufacturing Companies en-keyword=Resource-Based View kn-keyword=Resource-Based View END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=3 article-no= start-page=11 end-page=40 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Network Analysis of Interregional Information Exchange: A Study in the Takahashi River Basin Area kn-title=地域間での情報交流に関するネットワーク分析：高梁川流域圏での調査による en-subtitle= kn-subtitle= en-abstract=　This paper conducted network analysis focusing on information exchange among participating entities in the "Takahashi River Basin Economic Growth Strategy Council," operating within Okayama Prefecture's "Takahashi River Basin Core City Area." The Takahashi River Basin Collaborative Core City Area（ Takahashi River Basin Area）is a collaborative core city area encompassing ten municipalities located around the Takahashi River in Okayama Prefecture: Niimi City, Takahashi City, Soja City, Hayashima Town, Kurashiki City, Yakage Town, Ibara City, Asakuchi City, Satosho Town, and Kasaoka City. For the network analysis within the Takahashi River Basin Area, projects implemented within the area were classified into eight categories. A questionnaire survey was conducted regarding information exchange among participating entities for each project. Network metrics included calculating centrality indices（ degree centrality and betweenness centrality） for each project, along with density, transitivity, and reciprocity. By project type, tourism projects exhibited the densest network structure for information exchange. From a network perspective, tourism projects can be considered the most actively pursued initiative within the Takahashi River Basin area. Furthermore, across all projects, centrality indicators for specific administrative bodies and regional economic organizations, such as chambers of commerce and industry, generally showed high values. This clearly indicates their function as hubs for information exchange and as entities concentrating or dispersing information within the network. Based on the results of network analysis, two recommendations for future regional development in the Takahashi River Basin were proposed from a network perspective. The first is to aim for dense networks across all businesses by sharing the roles of information exchange hubs and information concentration/distribution entities among the entities involved, depending on the business. The second is to aim for a dense network overall by eliminating entities that are not participating at all in the Takahashi River Basin's information exchange network. kn-abstract=　本稿では，岡山県の「高梁川流域連携中枢都市圏」で2014年から開催されている「高梁川流域経済成長戦略会議」における参加主体間の情報交流についてのネットワーク分析を行った。高梁川流域連携中枢都市圏（高梁川流域圏）とは，岡山県高梁川周辺に位置する現在の新見市，高梁市，総社市，早島町，倉敷市，矢掛町，井原市，浅口市，里庄町，笠岡市の10自治体が参加している連携中枢都市圏である。高梁川流域圏におけるネットワーク分析に際しては，同圏域内で展開されている事業を８つに分類し，それぞれの事業に関する参加主体間の情報交流についてアンケート調査を行った。ネットワーク指標については事業ごとに次数中心性と媒介中心性の中心性指標を，また事業別に密度，推移性，相互性を算出した。事業別にみると，観光事業についての情報交流が最も密なネットワーク構造をしており，ネットワークの視点では観光事業が高梁川流域圏内で最も勢力的に行われている事業といえる。また全事業において特定の行政主体や商工会議所をはじめとする地域経済団体等の中心性指標が全体的に大きな値をとっており，ネットワークにおいて情報交流のハブや情報の集中・分散主体として機能していることが明らかになった。分析結果を踏まえ，ネットワークの視点から高梁川流域圏の今度の地域振興について２点提言した。１つは事業によって情報交流のハブや情報の集中・分散主体を主体間で分担することによって，すべての事業で密なネットワークを築くことを目指すことである。もう１つは高梁川流域圏の情報交流ネットワークに全く参加していない主体をなくすことで，全体的に密なネットワークを目指すことである。 en-copyright= kn-copyright= en-aut-name=NakamuraRyohei en-aut-sei=Nakamura en-aut-mei=Ryohei kn-aut-name=中村良平 kn-aut-sei=中村 kn-aut-mei=良平 aut-affil-num=1 ORCID= en-aut-name=YokotaNatsumi en-aut-sei=Yokota en-aut-mei=Natsumi kn-aut-name=横田夏実 kn-aut-sei=横田 kn-aut-mei=夏実 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=下関市役所 END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=9 article-no= start-page=e772 end-page=e780 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=Aging of the tricuspid valve annulus detected by photon-counting detector computed tomography: Importance of aortic root compression on occurrence of arrhythmias en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background The aortic root compresses the heart in elderly patients, potentially influencing the conduction system and causing atrial tachyarrhythmias. However, actual anatomic alterations in the right side of the heart because of aortic root compression have not yet been fully evaluated.
Objective This study aimed to elucidate the alterations in the tricuspid valve annulus (TVA) caused by aortic root compression using a 3-dimensional endoscopic view of the heart constructed by photon-counting detector computed tomography, an emerging medical technology.
Methods We analyzed 147 consecutive patients who underwent photon-counting detector computed tomography at our institute after excluding those with diseases that directly influenced the right side of the heart.
Results Aortic root compression caused significant TVA deformation. We defined severe TVA compression as the length of the TVA compressed by the aortic root ?80% of the major axis of the TVA. Severe compression was more prevalent in elderly patients (age ?75 years [44%]; P < .01). The distance between the membranous septum and ostium of the coronary sinus was shortened, whereas the cavotricuspid isthmus was elongated in older patients. The regression analysis identified aging as a significant contributor to TVA compression. The short minor and long major axes of the TVA, incidence of atrial tachyarrhythmias (74% vs 45%; P < .01), and atrioventricular conduction disturbances (35% vs 15%; P < .01) were more frequently observed in patients with severe compression.
Conclusion Aortic root compression deforms the TVA and alters the anatomic relationship between the atrioventricular conduction system and the cavotricuspid isthmus. Therefore, aortic root compression may contribute to the occurrence of atrial tachyarrhythmias and conduction disturbances in older patients. en-copyright= kn-copyright= en-aut-name=MoritaHiroshi en-aut-sei=Morita en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakagawaKoji en-aut-sei=Nakagawa en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NagaseSatoshi en-aut-sei=Nagase en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MorimotoYoshihisa en-aut-sei=Morimoto en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasudaTakuro en-aut-sei=Masuda en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UeokaAkira en-aut-sei=Ueoka en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AsadaSaori en-aut-sei=Asada en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyamotoMasakazu en-aut-sei=Miyamoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TohNorihisa en-aut-sei=Toh en-aut-mei=Norihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NishiiNobuhiro en-aut-sei=Nishii en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YuasaShinsuke en-aut-sei=Yuasa en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Cardiovascular Therapeutics, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=3 en-affil=Department of General Internal Medicine 3, Kawasaki Medical School General Medical Center kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=10 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=11 en-affil=Department of Cardiovascular Therapeutics, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine and Dentistry kn-affil= en-keyword=Tricuspid valve annulus kn-keyword=Tricuspid valve annulus en-keyword=Aortic root kn-keyword=Aortic root en-keyword=Photon-counting detector computed tomography kn-keyword=Photon-counting detector computed tomography en-keyword=Atrial tachyarrhythmia kn-keyword=Atrial tachyarrhythmia en-keyword=Conduction abnormality kn-keyword=Conduction abnormality END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=146 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260115 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=MMP-3 cleavage of Lamin A induces pro-migratory nuclear deformity, nucleophagy, and their autophagic secretion with extracellular vesicles in metastatic cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Matrix metalloproteinases (MMPs) are a family of zinc-dependent proteinases that cleave a plethora of substrates, including components of the extracellular matrix and cell-surface-associated proteins, as well as intracellular targets. MMPs have also been found in extracellular vesicles (EVs), such as exosomes. MMP-3 promotes tumor growth, epithelial-to-mesenchymal transition, genome instability, migration, invasion, and metastasis of cancer cells, and nuclear MMP-3 controls gene transcription. Intranuclear proteolysis by MMPs may significantly alter cancer progression. However, the nuclear substrates of MMP-3 have not been well investigated. In this study, we performed proteomic analyses to identify the nuclear substrates and EV proteins regulated by MMP-3. While rabidly metastatic colon cancer (LuM1) three-dimensionally cultured tumoroids secreted EVs containing 30 protein types, including Lamin A (LMNA), MMP-3, fibronectin (FN1), HSPA8 (Hsc70), β-actin (ACTB), and vimentin (VIM), CRISPR/Cas9-based knockout of MMP-3 reduced the secretion of these proteins in EVs. Notably, EV-bound cleaved Lamin secretion was confirmed by immunoelectron microscopy. Also, MMP-3 formed proteolytic dimers via its hemopexin-like repeat domains in nuclei. Many nuclear MMP-3-binding proteins, including Lamin A/C, histones, topoisomerases, and hnRNPs, were screened by co-immunoprecipitation followed by proteomics. Proteolytic MMP-3 overexpression generated a C-terminal 30-kDa fragment of Lamin A, whose cleavage site was defined via structural analysis. MMP-3 digestion of Lamin A induced nuclear deformity (atypia) required for cell migration in confined space. The cleaved Lamin A and MMP-3 were transported with autophagosomes (LC3B+), nucleophagosomes, and amphisomes (CD63?+?LC3B+) and co-secreted with EVs. Proteolytic MMP-3 also induced nuclear speckles of Lamin A, suggesting their roles in transcription and splicing. Clinical analysis revealed that high expressions of MMP3 and LMNA were significantly seen in head and neck squamous cell carcinoma (HNSC) than in the other 16 cancer types, and predicted poor prognosis of patients suffering from HNSC, pancreatic, rectum and lung adenocarcinomas at specific stages. Immunohistochemistry revealed that nuclear MMP-3 and cleaved Lamin were significantly higher expressed in stage IV metastatic HNSC cases than in stage I non-metastatic cases. Taken together, MMP3-cleavage of Lamin A induces nuclear deformity, nucleophagy, and their autophagic co-secretion with EVs in metastatic cancer. Also, high expression of MMP-3 and secretion of Lamin A can predict poor prognosis in multiple cancer types at specific stages. en-copyright= kn-copyright= en-aut-name=EguchiTakanori en-aut-sei=Eguchi en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TahaEman A. en-aut-sei=Taha en-aut-mei=Eman A. 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=TiwariVikas en-aut-sei=Tiwari en-aut-mei=Vikas kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakebeKatsuki en-aut-sei=Takebe en-aut-mei=Katsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=InoueTomohiro en-aut-sei=Inoue en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=XingLizi en-aut-sei=Xing en-aut-mei=Lizi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SogawaChiharu en-aut-sei=Sogawa en-aut-mei=Chiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=CalderwoodStuart K. en-aut-sei=Calderwood en-aut-mei=Stuart K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Biochemistry, Faculty of Science, Ain Shams 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= affil-num=4 en-affil=Council of Scientific & Industrial Research-Indian Institute of Toxicological Research kn-affil= affil-num=5 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Food and Health Sciences, Faculty of Environmental Studies, Hiroshima Institute of Technology kn-affil= affil-num=9 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Division of Molecular and Cellular Biology, Department of Radiation Oncology, Beth Israel Deaconess Medical Center, Harvard Medical School kn-affil= en-keyword=Lamin A (LMNA) kn-keyword=Lamin A (LMNA) en-keyword=Matrix metalloprotease (MMP) kn-keyword=Matrix metalloprotease (MMP) en-keyword=Proteolysis kn-keyword=Proteolysis en-keyword=Extracellular vesicle (EV) kn-keyword=Extracellular vesicle (EV) en-keyword=Exosome kn-keyword=Exosome en-keyword=Autophagy kn-keyword=Autophagy en-keyword=Amphisome kn-keyword=Amphisome en-keyword=Proteome kn-keyword=Proteome en-keyword=Nuclear deformity kn-keyword=Nuclear deformity en-keyword=Migration kn-keyword=Migration en-keyword=Metastatic cancer kn-keyword=Metastatic cancer en-keyword=Head and neck squamous cell carcinoma kn-keyword=Head and neck squamous cell carcinoma en-keyword=Colorectal cancer kn-keyword=Colorectal cancer END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=27 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between the incidence of infusion-related reactions by obinutuzumab and the dose of corticosteroid as premedication: a multicenter retrospective cohort study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Premedication with corticosteroids is recommended for prophylaxis against infusion-related reactions (IRRs) caused by obinutuzumab despite a lack of solid evidence regarding the dose of corticosteroids.
Methods The incidence rates of IRR in the high-dose and low-dose corticosteroid groups were investigated and compared using Student’s t-test.Univariable and multivariable logistic regression analyses were performed on patients to explore the risk of developing IRRs with obinutuzumab.
Results The incidence of IRRs in the high-dose and low-dose corticosteroid groups at the initial administration of obinutuzumab was 27.0% (41/152) and 48.4% (31/64), respectively, indicating that the high-dose group had a lower incidence of IRRs (p?=?0.002). The incidence of IRRs at the initial administration of obinutuzumab was significantly associated with the administration of first-generation histamine 1 receptor antagonist (OR?=?3.31, 95% CI: 1.16?9.47; reference: second-generation histamine 1 receptor antagonist), hydrocortisone (OR?=?7.21, 95% CI: 1.57?33.15; reference: dexamethasone), and methylprednisolone (OR?=?3.99, 95% CI :1.13?14.10; reference: dexamethasone), although no association was found with the lower dose of corticosteroids.
Conclusions Although no association was found between corticosteroid dosage and IRR when considering multiple factors, dexamethasone may be a better option than hydrocortisone or methylprednisolone for preventing IRR. Additionally, second-generation H1-receptor antagonists may be a better option than first-generation drugs. Certain combinations of premedications may influence infusion reaction incidence. en-copyright= kn-copyright= en-aut-name=OhtsuboTatsuya en-aut-sei=Ohtsubo en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoKazuhiro en-aut-sei=Yamamoto en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatumotoSaori en-aut-sei=Matumoto en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ItoKaori en-aut-sei=Ito en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SasaYuzuka en-aut-sei=Sasa en-aut-mei=Yuzuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TomishimaKosuke en-aut-sei=Tomishima en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=DoteSatoshi en-aut-sei=Dote en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MakiharaKatuya en-aut-sei=Makihara en-aut-mei=Katuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=WakasugiYoshinori en-aut-sei=Wakasugi en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MitsuieTsutomu en-aut-sei=Mitsuie en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YamagiwaKouhei en-aut-sei=Yamagiwa en-aut-mei=Kouhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=SatoKazuo en-aut-sei=Sato en-aut-mei=Kazuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=HasegawaHiroki en-aut-sei=Hasegawa en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=UoshimaNobuhiko en-aut-sei=Uoshima en-aut-mei=Nobuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=KitahiroYumi en-aut-sei=Kitahiro en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=TomoganeKanji en-aut-sei=Tomogane en-aut-mei=Kanji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Pharmacy, Japanese Red Cross Kyoto Daini Hospital kn-affil= affil-num=2 en-affil=Department of Integrated Clinical and Basic Pharmaceutical Sciences, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pharmacy, Japanese Red Cross Osaka Hospital kn-affil= affil-num=4 en-affil=Faculty of Pharmacy, Meijo University kn-affil= affil-num=5 en-affil=Department of Pharmacy, Kindai University Hospital kn-affil= affil-num=6 en-affil=Department of Pharmacy, Japanese Red Cross Kyoto Daiichi Hospital kn-affil= affil-num=7 en-affil=Department of Pharmacy, Kyoto-Katsura Hospital kn-affil= affil-num=8 en-affil=Department of Pharmacy, Yodogawa Christian Hospital kn-affil= affil-num=9 en-affil=Department of Pharmacy, Shiga University of Medical Science Hospital kn-affil= affil-num=10 en-affil=Department of Pharmacy, Japanese Red Cross Otsu Hospital kn-affil= affil-num=11 en-affil=Department of Pharmacy, Saiseikai Shiga Hospital kn-affil= affil-num=12 en-affil=Department of Pharmacy, Japan Baptist Hospital kn-affil= affil-num=13 en-affil=Department of Pharmacy, Rakuwakai Otowa Hospital kn-affil= affil-num=14 en-affil=Department of Hematology, Japanese Red Cross Kyoto Daini Hospital kn-affil= affil-num=15 en-affil=Department of Pharmacy, Kobe University Hospital kn-affil= affil-num=16 en-affil=Department of Pharmacy, Japanese Red Cross Kyoto Daini Hospital kn-affil= en-keyword=Obinutuzumab kn-keyword=Obinutuzumab en-keyword=Infusion-related reaction kn-keyword=Infusion-related reaction en-keyword=Premedication kn-keyword=Premedication en-keyword=Corticosteroids kn-keyword=Corticosteroids en-keyword=Histamine 1 receptor antagonists kn-keyword=Histamine 1 receptor antagonists END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=1 article-no= start-page=32 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260102 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Real-world comparative effectiveness of sarilumab versus Janus kinase inhibitors as monotherapy in rheumatoid arthritis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Sarilumab (SAR), an interleukin-6 receptor inhibitor (IL-6Ri), and Janus kinase inhibitors (JAKi) are approved options for rheumatoid arthritis (RA) when methotrexate (MTX) cannot be used. Real-world evidence for MTX-free monotherapy remains limited.
Methods: We conducted a multicenter retrospective cohort study of RA patients receiving SAR or JAKi as MTX-free monotherapy. To reduce confounding, 1:1 propensity score matching was performed in the overall cohort (n?=?252, 126 per group) and separately within treatment-line strata: Phase 2 first-line biologic/targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs: 45 per group), Phase 3 second-line b/tsDMARDs (53 per group), and Phase 3???third-line b/tsDMARDs (47 per group). Outcomes over 12 months included drug retention, change in Clinical Disease Activity Index (CDAI), glucocorticoid (GC) tapering and discontinuation, low disease activity (LDA, CDAI???10), and safety profiles. Predictors of LDA were evaluated with logistic regression. This multicenter real-world.
Results: Across matched strata by prior b/tsDMARDs, retention and CDAI change did not differ significantly between SAR and JAKi through 12 months. When classified by cause, adverse events (AEs)-related discontinuation was higher with JAKi, yielding lower AE-specific retention. Both groups demonstrated GC sparing overtime, with a greater increase in GC discontinuation for SAR than for JAKi in Phase 2. Baseline predictors of achieving LDA at 12 months included higher C-reactive protein (CRP) and platelet count (Plt) in both groups, with additional associations of younger age and lower hemoglobin (Hb) in the SAR. In safety analyses, overall AEs were less frequent with SAR than with JAKi, driven by lower risks of infection including herpes zoster, while other categories were similarly infrequent.
Conclusion: SAR and JAKi showed no statistically significant differences in 12-month retention or disease control in MTX-free monotherapy settings. Higher CRP and Plt with lower Hb, particularly in younger patients, identified better response to SAR and support biomarker guided selection between IL-6Ri and JAKi. In Phase 2, GC discontinuation with SAR suggests a practical strategy to reduce AEs while maintaining efficacy. Prospective studies should validate these findings and define actionable thresholds. en-copyright= kn-copyright= en-aut-name=NozakiYuji en-aut-sei=Nozaki en-aut-mei=Yuji kn-aut-name= kn-aut-sei=

Nanohybrid Material en-subtitle= kn-subtitle= en-abstract= kn-abstract=Synergistic effects of a multifunctional acrylate and a long-chain silane coupling agent were investigated in an organic?inorganic nanohybrid material. We tested the bond strength of nanohybrid composites treated with experimental primers containing silane coupling agents?3-methacryloxypropyl trimethoxysilane (γ-MPTS) or 8-methacryloxyoctyl trimethoxysilane (8-MOTS)?with or without multifunctional acrylates?trimethylolpropane triacrylate (A-TMPT) or dipentaerythritol hexaacrylate (A-DPH). Shear bond strength was evaluated after 24 h of water storage at 37 °C. Untreated control and silane-only groups exhibited low shear bond strengths (e.g., control: 2.4 ± 2.0 MPa) and failed exclusively at the adhesive interface. While addition of A-TMPT did not significantly improve bond strength, addition of A-DPH produced significantly higher shear bond strengths. Highest strength was achieved with 30% 8-MOTS and A-DPH (22.4 ± 6.1 MPa), followed by 20% γ-MPTS and A-DPH (19.0 ± 7.0 MPa), and A-DPH groups produced cohesive failures. Regardless of the silane used (γ-MPTS or 8-MOTS), incorporating A-DPH in the primer consistently yielded superior bond strengths, indicating a promising strategy for improved adhesion for such nanohybrid systems. These findings provide new insights into optimizing resin?filler interfacial interactions and may contribute to the development of restorative materials with improved long-term clinical durability. en-copyright= kn-copyright= en-aut-name=MaruoYukinori en-aut-sei=Maruo en-aut-mei=Yukinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshiharaKumiko en-aut-sei=Yoshihara en-aut-mei=Kumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IrieMasao en-aut-sei=Irie en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=KodamaNaoki en-aut-sei=Kodama en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshizaneMai en-aut-sei=Yoshizane en-aut-mei=Mai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AkiyamaKentaro en-aut-sei=Akiyama en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Prosthodontics, Okayama University kn-affil= affil-num=2 en-affil=Health Research Institute, National Institute of Advanced Industrial Science and Technology kn-affil= affil-num=3 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Advanced Research Center for Oral and Craniofacial Sciences, Dental School, Okayama University kn-affil= affil-num=5 en-affil=Department of Prosthodontics, Okayama University kn-affil= affil-num=6 en-affil=Department of Occlusal and Oral Functional Rehabilitation, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Occlusal and Oral Functional Rehabilitation, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=silane coupling kn-keyword=silane coupling en-keyword=multifunctional acrylate kn-keyword=multifunctional acrylate en-keyword=bond strength kn-keyword=bond strength en-keyword=resin kn-keyword=resin END start-ver=1.4 cd-journal=joma no-vol=115 cd-vols= no-issue=3 article-no= start-page=117345 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202607 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Investigation of the cefazolin inoculum effect in blood culture-isolated methicillin-susceptible Staphylococcus aureus strains: A Japanese multicenter study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Cefazolin inoculum effect (CInE) is a microbiological phenomenon where the MIC of cefazolin against methicillin-susceptible Staphylococcus aureus (MSSA) strains increases with higher bacterial volumes.
Method: We retrospectively investigated the prevalence and characteristics of the CInE among MSSA strains isolated from blood cultures at three Japanese hospitals. The collected isolates were screened for blaZ using PCR, and the cefazolin minimum inhibitory concentration (MIC) for the blaZ-positive MSSA isolates was measured at standard and high inoculum volumes. CInE-positive MSSA strains were defined as those with a cefazolin MIC ?16 μg/mL at 107 CFU/mL and ?8 μg/mL at 105 CFU/mL. In these blaZ-positive strains, we performed blaZ typing and tested a modified nitrocefin-based rapid examination to detect the CInE.
Results: We collected 329 MSSA strains isolated from blood cultures. Of these, 96 (29.2%) were positive for the blaZ gene, with the following genotypes: type A (15, 15.6%), type B (3, 3.1%), type C (77, 80.2%), type D (0, 0.0%), and non-type (1, 1.0%). Among 96 blaZ-positive MSSA isolates, 11 exhibited the CInE, all of which harbored blaZ type A. The rapid nitrocefin test detected CInE positivity with high sensitivity (100%), specificity (94.1%), and diagnostic accuracy (94.8%).
Conclusion: This study highlighted the low prevalence of CInE-presenting MSSA isolates in Japan. When the cefazolin MIC is ?1 μg/mL or the penicillin G MIC is ?0.25 μg/mL, the rapid nitrocefin test may be useful for considering the CInE in patients with high bacterial volume MSSA infections. en-copyright= kn-copyright= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujiShuma en-aut-sei=Tsuji en-aut-mei=Shuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GotohKazuyoshi en-aut-sei=Gotoh en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IioKoji en-aut-sei=Iio en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OgawaSakura en-aut-sei=Ogawa en-aut-mei=Sakura kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KoyanagiNorihito en-aut-sei=Koyanagi en-aut-mei=Norihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ItoYuji en-aut-sei=Ito en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KoganemaruHiroshi en-aut-sei=Koganemaru en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YoshidaAtsushi en-aut-sei=Yoshida en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=3 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=4 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Clinical Laboratory, Chutoen General Medical Center kn-affil= affil-num=7 en-affil=Department of General Internal Medicine, Chutoen General Medical Center kn-affil= affil-num=8 en-affil=Department of Infectious Diseases, Tokyo Metropolitan Institute for Geriatrics and Gerontology kn-affil= affil-num=9 en-affil=Department of Infectious Diseases, Tokyo Metropolitan Institute for Geriatrics and Gerontology kn-affil= affil-num=10 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= en-keyword=blaZ kn-keyword=blaZ en-keyword=Cefazolin inoculum effect kn-keyword=Cefazolin inoculum effect en-keyword=Methicillin-susceptible Staphylococcus aureus kn-keyword=Methicillin-susceptible Staphylococcus aureus en-keyword=Nitrocefin rapid test kn-keyword=Nitrocefin rapid test en-keyword=β-lactamase kn-keyword=β-lactamase END start-ver=1.4 cd-journal=joma no-vol=165 cd-vols= no-issue= article-no= start-page=105344 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Local immune response induced by intra-fin antigen injection in Japanese medaka (Oryzias latipes) is a useful model for immunological studies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Teleost fishes play a pivotal role in advancing our understanding of immune system evolution because they retain the ancient characteristics of vertebrate immunity, encompassing both innate and adaptive immune systems. Among these, innate immunity plays a critical role in fish as the first line of defense, coordinating rapid responses to pathogen infections. However, the lack of fish-specific immunological methodologies has limited progress in elucidating fish immune mechanisms. To better understand how the innate immune response develops and resolves in fish, detailed observation and integrative analysis of leukocytes at multiple time points is necessary. In the present study, an intra-fin injection method for observing local immune responses in Japanese medaka (Oryzias latipes) was tested and optimized to analyze the progression of zymosan-induced innate immune responses. Zymosan-injected medaka showed a rapid immune response characterized by leukocyte recruitment and phagocytosis. Using TG(FmpxP:mCherry) transgenic medaka with mCherry fluorescence driven by myeloperoxidase (mpx) promoter, granulocyte chemotaxis towards the site of zymosan entry was successfully visualized. The rapid increase in tumor necrosis factor α (tnfa), interleukin-1β (il1b), interleukin-6 (il6), and CXC motif chemokine ligand 8 (cxcl8) expressions in zymosan-injected anal fins provided a molecular basis for the visualized tissue-specific cellular response. Our study underscores the dynamic orchestration of immune components during the innate immune response in Japanese medaka and highlights their potential as a promising model for immunological research. en-copyright= kn-copyright= en-aut-name=RyuTsukasa en-aut-sei=Ryu en-aut-mei=Tsukasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshinoMizuki en-aut-sei=Yoshino en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TseWilliam Ka Fai en-aut-sei=Tse en-aut-mei=William Ka Fai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AnsaiSatoshi en-aut-sei=Ansai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IguchiTaisen en-aut-sei=Iguchi en-aut-mei=Taisen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KumarAnu en-aut-sei=Kumar en-aut-mei=Anu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SomamotoTomonori en-aut-sei=Somamoto en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakaoMiki en-aut-sei=Nakao en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OginoYukiko en-aut-sei=Ogino en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Bioresource and Bioenvironmental Sciences, Laboratory of Marine Biochemistry, Kyushu University kn-affil= affil-num=2 en-affil=Graduate School of Bioresource and Bioenvironmental Sciences, Laboratory of Marine Biology, Kyushu University kn-affil= affil-num=3 en-affil=Graduate School of Bioresource and Bioenvironmental Sciences, Laboratory of Developmental Disorders and Toxicology, Kyushu University kn-affil= affil-num=4 en-affil=Ushimado Marine Institute, Faculty of Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Nanobioscience, Yokohama City University kn-affil= affil-num=6 en-affil=Commonwealth Scientific and Industrial Research Organisation, CSIRO Environment kn-affil= affil-num=7 en-affil=Graduate School of Bioresource and Bioenvironmental Sciences, Laboratory of Marine Biochemistry, Kyushu University kn-affil= affil-num=8 en-affil=Graduate School of Bioresource and Bioenvironmental Sciences, Laboratory of Marine Biochemistry, Kyushu University kn-affil= affil-num=9 en-affil=Center for Promotion of International Education and Research, Faculty of Agriculture, Kyushu University kn-affil= en-keyword=Chemotaxis kn-keyword=Chemotaxis en-keyword=Local immunity kn-keyword=Local immunity en-keyword=Inflammation kn-keyword=Inflammation en-keyword=Innate immunity kn-keyword=Innate immunity en-keyword=Phagocytosis kn-keyword=Phagocytosis en-keyword=Zymosan kn-keyword=Zymosan 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=2026 dt-pub=20260203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Real-world six-month outcomes after switching from aflibercept 2 mg to aflibercept 8 mg for neovascular age-related macular degeneration en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose To investigate 6-month outcomes in eyes with neovascular age-related macular degeneration (nAMD) switched from intravitreal aflibercept 2 mg to intravitreal aflibercept 8 mg.
Study design Retrospective observational study.
Methods We reviewed records of consecutive nAMD eyes switched from aflibercept 2 mg to 8 mg. In eyes continuing aflibercept 8 mg, best-corrected visual acuity (BCVA), treatment intervals, and anatomical/exudative parameters were evaluated at 6 months. In eyes that could not continue, reasons for discontinuation were examined.
Results Forty-four eyes from 44 patients were included. At 6 months, 35 eyes (79.5%) continued and 9 (20.5%) discontinued aflibercept 8 mg. Discontinuing eyes had significantly shorter pre-switch treatment intervals and more frequent prior therapies than continuing eyes. In the continuation group, BCVA remained stable (median 0.05 to 0.00 logMAR, P = 0.351), while the treatment interval was significantly extended (median 7.0 to 9.0 weeks, P < 0.001). Central retinal thickness and pigment epithelial detachment height decreased significantly (P = 0.035 and P = 0.021, respectively). The proportion of eyes with subretinal fluid significantly decreased from 74.3 to 37.1% (P = 0.003). Of the discontinuations, 4 were due to worsening exudation and 5 to inability to extend to ?8 weeks as required by labeling. No intraocular inflammation or serious adverse events occurred.
Conclusions Switching to aflibercept 8?mg achieved anatomical improvements and longer treatment intervals in ~80% of nAMD cases, suggesting it may be a useful alternative to aflibercept 2 mg. However, continuation may be difficult in refractory cases requiring frequent injections before switching. en-copyright= kn-copyright= en-aut-name=KindoHiroya en-aut-sei=Kindo en-aut-mei=Hiroya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HosokawaMio Morizane en-aut-sei=Hosokawa en-aut-mei=Mio Morizane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OuchiChihiro en-aut-sei=Ouchi en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 ORCID= en-aut-name=HayashiJunko en-aut-sei=Hayashi en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Ophthalmology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Aflibercept 8 mg kn-keyword=Aflibercept 8 mg en-keyword=Neovascular age-related macular degeneration kn-keyword=Neovascular age-related macular degeneration en-keyword=Treat-and-extend kn-keyword=Treat-and-extend en-keyword=Switching kn-keyword=Switching en-keyword=Treatment interval kn-keyword=Treatment interval END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=6 article-no= start-page=oeaf162 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251031 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sex differences in the progression of cardiovascular?kidney?metabolic syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims Cardiovascular?kidney?metabolic (CKM) syndrome is a novel disease concept; however, sex differences in its progression remain uncertain. This study aimed to quantify the risk of cardiovascular disease (CVD) events across CKM stages and to explore sex differences in this association.
Methods and results We included 1 332 436 individuals (581 423 males and 751 013 females) from the DeSC database between 2014 and 2023 who had no prior CVD (i.e. CKM Stage 4). CKM stages were categorized as follows: Stage 0 (no CKM risk factors); Stage 1 (excess or dysfunctional adiposity); Stage 2 [metabolic risk factors and chronic kidney diseases (CKD)], and Stage 3 (subclinical CVD). We used Cox models to examine the association of CKM stages with the risk of CVD events (newly developed CKM Stage 4), including myocardial infarction, stroke, heart failure, atrial fibrillation, and peripheral artery disease. The progression from CKM Stages 0 to 3 showed a dose-dependent increase in adjusted hazard ratios (HR) for developing CVD events, with the highest risk at Stage 3 [1.85 (95% CI: 1.80?1.90)]. A similar pattern was observed in both males and females. However, the magnitude of associations for CKM stages 1?3 differed between the sexes: HR by Stage 1, 1.12 (1.04?1.21) vs. 1.12 (1.07?1.16); by Stage 2, 1.78 (1.69?1.88) vs. 1.43 (1.39?1.48); by Stage 3, 1.99 (1.89?2.10) vs. 1.82 (1.76?1.88); and P-for-interaction values were 0.87, < 0.001, and 0.005, respectively.
Conclusion In this large nationwide cohort, CKM stage progression was associated with higher CVD risk in both sexes, with modest sex-specific differences. These findings highlight the value of CKM staging for early risk assessment, regardless of sex. en-copyright= kn-copyright= en-aut-name=TayaSatoshi en-aut-sei=Taya en-aut-mei=Satoshi kn-aut-name=

muscle satellite cells is crucial for skeletal muscle remodelling en-subtitle= kn-subtitle= en-abstract= kn-abstract=Skeletal muscle remodelling relies on muscle stem cells (MuSCs) for regeneration after injury and hypertrophy in response to mechanical loading. However, the mechanisms that trigger MuSC activation and proliferation remain unclear. Transient receptor potential vanilloid 2 (TRPV2) ion channels respond to insulin-like growth factor-1 and mechanical stimuli to regulate the biological characteristics of various cells. Using a temporally inducible MuSC-specific conditional knockout (cKO) mouse, we show that TRPV2 regulates MuSC function and is essential for muscle remodelling. In cultured myofibre, MuSCs express TRPV2 and exhibit Ca2+ responses to the TRPV2 agonists 2-aminoethoxydiphenyl borate and probenecid, which are abolished upon TRPV2 deletion. TRPV2-deficient MuSCs exhibit reduced paired box 7 (Pax7) expression and impaired proliferation, suggesting TRPV2 is a factor that regulates the early stage of MuSC function. Myotube formation in MuSCs was enhanced by overexpression of TRPV2 and suppressed by TRPV2 deficiency, suggesting that TRPV2 is a factor that promotes myogenesis. Muscle-administered cardiotoxin promoted muscle regeneration and resulted in the appearance of numerous Pax7-positive MuSCs between myofibres. MuSC-specific TRPV2 cKO mice exhibit substantially impaired muscle regeneration after cardiotoxin-induced injury, drastically reducing Pax7-positive MuSCs between myofibres. In floxed mice, mechanical loading via synergist ablation induces hypertrophy and greatly increases the number of myonuclei per myofibre. In contrast, MuSC-specific TRPV2 cKO mice show no changes in myofibre thickness or nuclear number, either at baseline or after mechanical loading. Mechanical loading of floxed mice increased TRPV2+/Pax7+ double-positive MuSCs, but MuSC-specific TRPV2 cKO mice showed no change. Additionally, MuSCs exhibit Ca2+ responses to hypo-osmotic stimuli, which are suppressed by TRPV2 inhibitors and TRPV2 deletion, suggesting that MuSCs exhibit TRPV2-dependent mechanical responses. These results establish TRPV2 as a critical regulator of MuSC-mediated muscle remodelling, an important finding that may lead to therapeutic strategies for muscle repair and adaptation. en-copyright= kn-copyright= en-aut-name=ChenYanzhu en-aut-sei=Chen en-aut-mei=Yanzhu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatanosakaKimiaki en-aut-sei=Katanosaka en-aut-mei=Kimiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShibuyaMakoto en-aut-sei=Shibuya en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DongYubing en-aut-sei=Dong en-aut-mei=Yubing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ZhangLidan en-aut-sei=Zhang en-aut-mei=Lidan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KanagawaMotoi en-aut-sei=Kanagawa en-aut-mei=Motoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FukadaSo-ichiro en-aut-sei=Fukada en-aut-mei=So-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NaruseKeiji en-aut-sei=Naruse en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KatanosakaYuki en-aut-sei=Katanosaka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Biomedical Sciences, College of Life and Health Sciences, Chubu University kn-affil= affil-num=3 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Laboratory of Stem Cell Regeneration and Adaptation, Graduate School of Pharmaceutical Sciences, The University of Osaka kn-affil= affil-num=6 en-affil=Department of Cell Biology and Molecular Medicine, Ehime University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Laboratory of Stem Cell Regeneration and Adaptation, Graduate School of Pharmaceutical Sciences, The University of Osaka kn-affil= affil-num=8 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=411 cd-vols= no-issue=1 article-no= start-page=22 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The impact of liver transection depth on surgical difficulty in robotic versus laparoscopic limited liver resection (TAKUMI-5) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Although robotic liver resection (RLR) has gained popularity worldwide, limited liver resection remains the mainstay of RLR. This study aimed to investigate the effect of parameters, including liver transection depth (LTD), on surgical difficulty in limited RLR compared with limited laparoscopic liver resection (LLR).
Methods This retrospective study included 105 patients who underwent limited RLR (n?=?56) or LLR (n?=?49) at our institution between January 2018 and December 2024. After comparing outcomes of RLR and LLR, multivariate analyses were performed to examine effect of LTD on surgical difficulty (defined as prolonged operative time). Moreover, outcomes stratified by LTD cut-off values were compared between the groups.
Results Median LTD was similar between groups (RLR vs. LLR: 2.6 vs. 2.6 cm, P?=?0.77). LTD was significantly correlated with operative time for both procedures (RLR, R? = 0.07, P?=?0.042; LLR, R? = 0.08, P?=?0.046). Multivariate analyses demonstrated that LLR (odds ratio, 6.9; P??2.5 cm), the RLR group had significantly shorter operative time (145 vs. 231 min, P? Conclusion This study investigated impact of LTD on surgical outcomes in patients who underwent limited RLR compared to those who underwent limited LLR. LTD may be a useful parameter for estimating surgical difficulty in limited RLR. Moreover, robotic surgery may be favorable for deeper and limited liver resections. en-copyright= kn-copyright= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu 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=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ItoAtene en-aut-sei=Ito en-aut-mei=Atene kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishiyamaTakeyoshi en-aut-sei=Nishiyama en-aut-mei=Takeyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NagaiYasuo en-aut-sei=Nagai en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YokoyamaShohei en-aut-sei=Yokoyama en-aut-mei=Shohei 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, 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 Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Robotic surgery kn-keyword=Robotic surgery en-keyword=Laparoscopic surgery kn-keyword=Laparoscopic surgery en-keyword=Limited liver resection kn-keyword=Limited liver resection en-keyword=Textbook outcome kn-keyword=Textbook outcome END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=6 article-no= start-page=e85768 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=Severe Anemia Caused by a Colorectal Lipoma With Central Erosions: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Colorectal lipomas are benign tumors that are often asymptomatic and discovered incidentally. In most cases, they can be managed conservatively with observation. We report the case of a man in his 70s with a colorectal lipoma located in the cecum. An investigation into his severe anemia led to the suspicion that the cecal lipoma was the underlying cause. An ileocecal resection was performed. Erosions were observed at the center of the lipoma. Although small colorectal lipomas are generally asymptomatic and rarely cause anemia, periodic endoscopic examinations are recommended. These lesions should be considered in the differential diagnosis of lower gastrointestinal bleeding. en-copyright= kn-copyright= en-aut-name=YoshidaYusuke en-aut-sei=Yoshida en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=WatanabeKo en-aut-sei=Watanabe en-aut-mei=Ko 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 Hospital kn-affil= affil-num=4 en-affil=Department of Pathology, Okayama University Hospital 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=anemia kn-keyword=anemia en-keyword=bleeding lipoma kn-keyword=bleeding lipoma en-keyword=colorectal lipoma kn-keyword=colorectal lipoma en-keyword=laparoscopic surgery kn-keyword=laparoscopic surgery en-keyword=mucosal erosion kn-keyword=mucosal erosion END start-ver=1.4 cd-journal=joma no-vol=411 cd-vols= no-issue=1 article-no= start-page=21 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Surgical outcomes and patient selection in nonagenarians with colon cancer: a comparative multi-institutional study of laparoscopic and open approaches en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose The appropriate surgical approach for colon cancer (CC) in nonagenarian patients remains a subject of clinical debate. This study aimed to compare the short-term outcomes of laparoscopic (Lap) versus open (Open) surgery in patients aged???90 years with resectable colon cancer.
Methods This multi-institutional retrospective cohort study included oldest-old patientswith pathological Stage II/III CC who underwent elective surgery at 15 hospitals between 2011 and 2022. Patients with rectal cancer, Stage 0/I/IV disease, or emergency surgery were excluded. To address selection bias, inverse-probability-weighted regression adjustment and stabilized inverse probability of treatment weighting (sIPTW) were applied. The primary outcome was postoperative complications; secondary outcomes included overall survival (OS).
Results Median age was 92 years in both groups. Before adjustment, the Lap group had a higher proportion of female patients (p?=?0.038) and lower ASA scores (p?=?0.01). Laparoscopic surgery was associated with a significantly longer operative time (220 vs. 171 min, p?=?0.046) but less intraoperative blood loss (10 vs. 78 mL, p? Conclusion Both laparoscopic and open surgery are feasible options for selected nonagenarians with colon cancer. Laparoscopic surgery may offer benefits in terms of reduced blood loss and shorter hospitalization, despite longer operative times. Careful patient selection considering frailty and comorbidities is essential in determining the most appropriate surgical approach. en-copyright= kn-copyright= en-aut-name=ShojiRyohei en-aut-sei=Shoji

C-reactive protein as a predictive biomarker for postoperative complications following robot-assisted surgery for rectal cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=This retrospective cohort study aimed to assess the predictive value of early postoperative C-reactive protein (CRP) levels for complications following robot-assisted rectal surgery (RARS) for rectal cancer. We analyzed data from 117 consecutive patients who underwent elective RARS at Okayama University Hospital between September 2020 and January 2025. Serum CRP levels were routinely measured preoperatively and on postoperative days (POD) 1 and 4. The primary outcome was the occurrence of any postoperative complication within 30 days, classified according to the Clavien?Dindo grading system. Postoperative complications were observed in 26 patients, representing 22.2% of the cohort. Univariate analysis revealed that several factors were significantly associated with complications, including older age, higher ASA score, neoadjuvant therapy, stoma creation, prolonged operative time, and elevated CRP levels on POD1 and POD4. Notably, multivariate logistic regression analysis identified POD1 CRP as a robust independent predictor of overall postoperative complications (adjusted odds ratio 0.77, 95% confidence interval (CI) [0.63?0.93], p? Methods: This cross-sectional multicentre study surveyed 133 adults with DS (mean age 50.1?years) residing in 45 welfare facilities across Japan in 2019. Dementia was diagnosed by a consensus panel of physicians using established criteria (DSM-5, ICD-10, DC-LD) after comprehensive assessments, including the Japanese version of the Dementia Screening Questionnaire for Individuals with Intellectual Disabilities (DSQIID-J). Logistic regression analysis was performed to identify factors independently associated with dementia.
Results: Forty-six participants (34.6%) were diagnosed with dementia. The prevalence rose sharply with age: 0% in their 30s, 30.8% in their 40s, 31.6% in their 50s and 65.5% in their 60s. After adjusting for covariates, older age, female sex, dyslipidaemia and visual impairment were independently associated with dementia.
Conclusions: This study, the largest of its kind in Asia, confirms a high prevalence of dementia in institutionalized Japanese adults with DS. Crucially, this study is the first to identify dyslipidaemia and visual impairment as independent and potentially modifiable risk factors in this population. These findings highlight tangible targets for clinical interventions aimed at mitigating dementia risk in people with DS. en-copyright= kn-copyright= en-aut-name=TakenoshitaShintaro en-aut-sei=Takenoshita en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TeradaSeishi en-aut-sei=Terada en-aut-mei=Seishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InoueTomokazu en-aut-sei=Inoue en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KurozumiTaku en-aut-sei=Kurozumi en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakakiManabu en-aut-sei=Takaki en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KuwanoRyozo en-aut-sei=Kuwano en-aut-mei=Ryozo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuemitsuShigeru en-aut-sei=Suemitsu en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Neuropsychiatry, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Neuropsychiatry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Asahigawaso Research Institute, Social Welfare Corporation Asahigawaso kn-affil= affil-num=4 en-affil=Asahigawaso Research Institute, Social Welfare Corporation Asahigawaso kn-affil= affil-num=5 en-affil=Department of Neuropsychiatry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Asahigawaso Research Institute, Social Welfare Corporation Asahigawaso kn-affil= affil-num=7 en-affil=Asahigawaso Research Institute, Social Welfare Corporation Asahigawaso kn-affil= END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=RP99825 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250618 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Stimulatory and inhibitory G-protein signaling relays drive cAMP accumulation for timely metamorphosis in the chordate Ciona en-subtitle= kn-subtitle= en-abstract= kn-abstract=Larvae of the ascidian Ciona initiate metamorphosis tens of minutes after adhesion to a substratum via their adhesive organ. The gap between adhesion and metamorphosis initiation is suggested to ensure the rigidity of adhesion, allowing Ciona to maintain settlement after losing locomotive activity through metamorphosis. The mechanism producing the gap is unknown. Here, by combining gene functional analyses, pharmacological analyses, and live imaging, we propose that the gap represents the time required for sufficient cyclic adenosine monophosphate (cAMP) accumulation to trigger metamorphosis. Not only the Gs pathway but also the Gi and Gq pathways are involved in the initiation of metamorphosis in the downstream signaling cascade of the neurotransmitter GABA, the known initiator of Ciona metamorphosis. The mutual crosstalk of stimulatory and inhibitory G-proteins functions as the accelerator and brake for cAMP production, ensuring the faithful initiation of metamorphosis at an appropriate time and in the right situation. en-copyright= kn-copyright= en-aut-name=HozumiAkiko en-aut-sei=Hozumi en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TotsukaNozomu M en-aut-sei=Totsuka en-aut-mei=Nozomu M kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OnoderaArata en-aut-sei=Onodera en-aut-mei=Arata kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangYanbin en-aut-sei=Wang en-aut-mei=Yanbin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HamadaMayuko en-aut-sei=Hamada en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShiraishiAkira en-aut-sei=Shiraishi en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SatakeHonoo en-aut-sei=Satake en-aut-mei=Honoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HorieTakeo en-aut-sei=Horie en-aut-mei=Takeo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HottaKohji en-aut-sei=Hotta en-aut-mei=Kohji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SasakuraYasunori en-aut-sei=Sasakura en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Shimoda Marine Research Center, University of Tsukuba kn-affil= affil-num=2 en-affil=Department of Biosciences and Informatics, Faculty of Science and Technology, Keio University kn-affil= affil-num=3 en-affil=Shimoda Marine Research Center, University of Tsukuba kn-affil= affil-num=4 en-affil=Shimoda Marine Research Center, University of Tsukuba kn-affil= affil-num=5 en-affil=Ushimado Marine Institute, Okayama University kn-affil= affil-num=6 en-affil=Bioorganic Research Institute, Suntory Foundation for Life Sciences kn-affil= affil-num=7 en-affil=Bioorganic Research Institute, Suntory Foundation for Life Sciences kn-affil= affil-num=8 en-affil=Laboratory for Single-cell Neurobiology, Graduate School of Frontier Biosciences, Osaka University kn-affil= affil-num=9 en-affil=Department of Biosciences and Informatics, Faculty of Science and Technology, Keio University kn-affil= affil-num=10 en-affil=Shimoda Marine Research Center, University of Tsukuba kn-affil= END start-ver=1.4 cd-journal=joma no-vol=52 cd-vols= no-issue=1 article-no= start-page=72 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Preferential sacral fracture sites in fragility fractures of the pelvis type IVb and comparison of internal fixation methods: CT-based morphological mapping and finite element analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Fragility fractures of the pelvis (FFP) classified as Rommens-Hoffman type IVb are associated with spinopelvic dissociation and are generally considered to require surgical intervention. This study aimed to clarify the localization patterns of FFP type IVb and compare the biomechanical stability of different internal fixation techniques.
Methods In this retrospective study, morphologic mapping of sacral fracture lines was performed in 36 patients with FFP type IVb. Based on the mapping results, a finite element (FE) model of FFP type IVb was developed to evaluate the biomechanical stability of ilio-sacral screw (ISS) fixation, trans-sacral screw (TSS) fixation, spinopelvic fixation (SPF; On each side, L5 pedicle screw was connected to two iliac screws with a rod, and the bilateral constructs were linked using a cross-connector.), and bilateral triangular fixation (one TSS at S1 combined with SPF mentioned above) using finite element analysis (FEA).
Results Morphologic mapping showed that the sacrum fracture transverse line tended to pass between the S1-2 transverse lines. Although bilateral triangular fixation and SPF provided the highest stability in both U-type and H-type fractures, a TSS for U-type and two TSSs for H-type also demonstrated comparable levels of stability. ISS-based methods showed greater displacements.
Conclusion TSS-based fixation may provide stability comparable to bilateral triangular fixation and SPF in FFP type IVb, with less invasiveness when anatomy permits. Further studies are needed to optimize treatment strategies for this complex injury. en-copyright= kn-copyright= en-aut-name=NaniwaShuichi en-aut-sei=Naniwa en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=HasegawaTsubasa en-aut-sei=Hasegawa en-aut-mei=Tsubasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AndoTeruhiko en-aut-sei=Ando en-aut-mei=Teruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkudaRyuichiro en-aut-sei=Okuda en-aut-mei=Ryuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=MochizukiYusuke en-aut-sei=Mochizuki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamakawaYasuaki en-aut-sei=Yamakawa en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=HanakawaShiro en-aut-sei=Hanakawa en-aut-mei=Shiro 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, Section of Medicine, Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Musculoskeletal Traumatology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University, kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Section of Medicine, Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Section of Medicine, Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Section of Medicine, Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=7 en-affil=Department of Emergency Health Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Kochi Health Sciences Center kn-affil= affil-num=9 en-affil=Department of Musculoskeletal Health Promotion, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Okayama Saidaiji Hospital kn-affil= affil-num=11 en-affil=Department of Orthopedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Fragility fractures of the pelvis kn-keyword=Fragility fractures of the pelvis en-keyword=Spinopelvic dissociation kn-keyword=Spinopelvic dissociation en-keyword=Finite element analysis kn-keyword=Finite element analysis en-keyword=Internal fixation kn-keyword=Internal fixation END start-ver=1.4 cd-journal=joma no-vol=46 cd-vols= no-issue=1 article-no= start-page=e70089 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260111 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lifestyle Factors and Current Alcohol Consumption Among Japanese Adolescents During the COVID-19 Pandemic: A Nationwide Cross-Sectional Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The COVID-19 pandemic may have influenced drinking behaviors in minors by disrupting daily routines and increasing psychosocial stress, although alcohol use among Japanese adolescents has declined in recent years. We aimed to clarify the relationships between current alcohol consumption and lifestyle factors during the COVID-19 pandemic based on a nationwide cross-sectional survey.
Methods: This cross-sectional study analyzed data from the 2021 Lifestyle Survey of Adolescents, a nationwide survey conducted in Japan during the COVID-19 pandemic. A total of 15?549 junior and senior high school students (7645 boys and 7904 girls) were included. Current alcohol consumption was defined as drinking on at least 1?day in the past 30?days. Multivariable logistic regression analyses were used to examine associations between current alcohol consumption and lifestyle factors, including irregular sleep patterns, irregular dietary habits, and increased screen time. Sex-stratified analyses and interaction tests were also performed.
Results: The overall prevalence of current alcohol consumption was 2.1%, with slightly higher rates among boys (2.2%) than girls (2.0%). Current alcohol consumption was significantly associated with irregular sleep patterns (odds ratio [OR]?=?1.51; 95% confidence interval [CI], 1.17?1.95) and irregular dietary habits (OR?=?1.68; 95% CI, 1.18?2.40). An association with increased screen time was also observed (OR?=?1.29; 95% CI, 1.00?1.69), particularly among boys. A significant interaction by sex was detected for irregular sleep patterns (p for interaction?=?0.013).
Conclusions: Alcohol consumption among Japanese adolescents was associated with irregular sleep and dietary habits and, among boys, with increased screen time. These findings highlight the importance of promoting regular routines and addressing lifestyle-related risks to prevent current alcohol consumption among adolescents during public health crises.

en-abstract= kn-abstract=Aims Right ventricular dysfunction is a well-established prognostic marker in patients with heart failure (HF). However, the prognostic significance of right atrial (RA) function remains unclear. Given its sensitivity to systemic congestion, RA function may provide additional insights into HF disease progression and management. This study aimed to investigate whether RA reservoir function serves as an independent prognostic indicator in patients with chronic HF.
Methods A total of 613 patients with chronic HF and a left ventricular (LV) ejection fraction of less than 50% who underwent echocardiographic assessment at Okayama University Hospital between January 2018 and March 2023 were included (median age: 68 (58?76) years; 69% male). RA reservoir function was quantified using two-dimensional speckle-tracking echocardiography. The primary endpoint was cardiovascular death or HF-related hospitalization. Kaplan?Meier survival analysis was performed to examine the association between RA reservoir function and clinical outcomes.
Results During a median follow-up period of 41 months (range: 12?91 months), 119 patients experienced cardiac events. Compared with event-free patients, those with cardiac events exhibited a significantly larger RA maximum volume index (38 mL/m2 vs. 31 mL/m2, P??20%, even without RA volume enlargement (log-rank test, P? Conclusions In patients who experienced adverse cardiac events, a reduced RASr and an increased RA maximum volume were observed. Furthermore, a reduced RASr was independently associated with an increased risk of cardiovascular death and HF-related hospitalization in patients with chronic HF and LV dysfunction. These findings indicate that RASr may serve as a valuable prognostic marker for the risk stratification and management of chronic HF. en-copyright= kn-copyright= en-aut-name=NakayamaRie en-aut-sei=Nakayama en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakayaYoichi en-aut-sei=Takaya en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakashimaMitsutaka en-aut-sei=Nakashima en-aut-mei=Mitsutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=TohNorihisa en-aut-sei=Toh en-aut-mei=Norihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ToruMiyoshi en-aut-sei=Toru en-aut-mei=Miyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YuasaShinsuke en-aut-sei=Yuasa en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= en-keyword=Right atrial function kn-keyword=Right atrial function en-keyword=Right atrial strain kn-keyword=Right atrial strain en-keyword=Chronic heart failure kn-keyword=Chronic heart failure en-keyword=Echocardiography kn-keyword=Echocardiography END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=11 article-no= start-page=e2543107 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Trastuzumab Deruxtecan for ERBB2-Mutant Metastatic Non?Small Cell Lung Cancer With or Without Brain Metastases: A Secondary Analysis of Randomized Clinical Trials en-subtitle= kn-subtitle= en-abstract= kn-abstract=Importance Brain metastases reduce overall survival rates of patients with non?small cell lung cancer (NSCLC); patients with epidermal growth factor receptor 2 (ERBB2 [formerly HER2])?mutant NSCLC are more likely to have baseline brain metastases. Trastuzumab deruxtecan (T-DXd) is an approved ERBB2-directed treatment for previously treated unresectable or metastatic ERBB2-mutant NSCLC.
Objective To assess the clinical effectiveness and safety of T-DXd 5.4 mg/kg and 6.4 mg/kg doses in patients with previously treated ERBB2-mutant metastatic NSCLC with or without untreated or previously treated stable brain metastases.
Design, Setting, and Participants This post hoc secondary analysis pooled patients from the DESTINY-Lung01 (data cutoff date: December 3, 2021) and DESTINY-Lung02 (data cutoff date: December 23, 2022) clinical trials by T-DXd dose (5.4 mg/kg and 6.4 mg/kg). DESTINY-Lung01 was a multicenter, open-label, 2-cohort, nonrandomized phase 2 study, while DESTINY-Lung02 was a dose-blinded, multicenter, 2-cohort, randomized phase 2 study. Participants had a previously treated ERBB2-mutant metastatic NSCLC with or without untreated or previously treated stable brain metastases at baseline. All statistical analyses were performed from April 2023 to October 2024.
Intervention Patients received a T-DXd dose of either 5.4 mg/kg or 6.4 mg/kg intravenously every 3 weeks.
Main Outcome and Measure Systemic and intracranial effectiveness by blinded independent central review using RECIST (Response Evaluation Criteria in Solid Tumors) version 1.1, sites of progression, and safety.
Results This analysis included 102 patients in the T-DXd 5.4-mg/kg dose group (65 females [64%]; median [range] age, 57.5 [37.0-83.0] years and 59.5 [30.0-79.0] years in patients with and without brain metastases, respectively) and 141 patients in the T-DXd 6.4-mg/kg dose group (94 females [67%]; median [range] age, 62.5 [29.0-88.0] years and 59.0 [27.0-83.0] years in patients with and without brain metastases, respectively). In each group, 31% (32 of 102) and 38% (54 of 141) of patients, respectively, had baseline brain metastases and 53% (17 of 32) and 44% (24 of 54), respectively, received prior brain metastasis treatment. In patients with and without brain metastases, systemic confirmed objective response rates (ORRs) were 47% (15 of 32; 95% CI, 29%-65%) and 50% (35 of 70; 95% CI, 38%-62%), respectively, with the T-DXd 5.4-mg/kg dose, and 50% (27 of 54; 95% CI, 36%-64%) and 59% (51 of 87; 95% CI, 48%-69%) with the T-DXd 6.4-mg/kg dose. Median progression-free survival was 7.1 (95% CI, 5.5-9.7) months in the T-DXd 5.4-mg/kg dose group and 7.1 (95% CI, 4.5-9.6) months in the T-DXd 6.4-mg/kg dose group of patients with baseline brain metastases. Among patients with measurable baseline brain metastases, intracranial confirmed ORRs were 50% (7 of 14; 95% CI, 23%-77%) with the T-DXd 5.4-mg/kg dose and 30% (9 of 30; 95% CI, 15%-49%) with the T-DXd 6.4-mg/kg dose. At both doses, the safety profile of T-DXd was generally manageable, regardless of baseline brain metastases, favoring the T-DXd 5.4 mg/kg dose.
Conclusions and Relevance In this secondary analysis, T-DXd at the approved dose of 5.4 mg/kg showed antitumor activity in patients with previously treated ERBB2-mutant metastatic NSCLC with or without brain metastases. This finding supports T-DXd 5.4 mg/kg use in this population. en-copyright= kn-copyright= en-aut-name=J?nnePasi A. en-aut-sei=J?nne en-aut-mei=Pasi A. kn-aut-name= kn-aut-sei= kn-aut-mei=

DESTINY-Lung02 primary analysis (December 23, 2022, data cutoff). This final analysis evaluated T-DXd efficacy and safety after 8 additional months of follow-up, including clinically relevant subgroups and patient-reported outcomes.
Methods: DESTINY-Lung02 was a randomized, dose-blinded, multicenter, phase 2 trial. Patients with previously treated HER2m mNSCLC were randomized 2:1 to receive T-DXd 5.4 or 6.4 mg/kg once every 3 weeks. Primary end point was confirmed objective response rate by blinded independent central review.
Results: As of August 25, 2023, 102 and 50 patients had received T-DXd 5.4 or 6.4 mg/kg, respectively. Median follow-up (Q1?Q3) was 15.8 (8.2?20.7) months and 16.5 (9.4?20.8) months, respectively. Confirmed objective response rate (95% confidence interval) was 50.0% (51/102; 39.9%?60.1%) and 56.0% (28/50; 41.3%?70.0%), respectively. Safety profile was acceptable and generally manageable. Accordingly, median treatment duration (Q1?Q3) was 7.7 (3.7?14.4) months and 8.3 (2.8?13.1) months; drug-related grade 3 or higher treatment-emergent adverse events occurred in 39.6% (40/101) and 60.0% (30/50), with nausea most common (67.3% [68/101], 82.0% [41/50]). Adjudicated drug-related interstitial lung disease occurred in 14.9% (15/101) and 32.0% (16/50), mostly grade 1 or 2 with one grade 5 in each arm. Health-related quality of life was preserved for the duration of T-DXd treatment while sample size was sufficient for analysis, with no adverse effects on health-related quality of life observed at either dose.
Conclusions: T-DXd demonstrated strong and durable responses at both doses, with no clinically significant changes in toxicity. The approved 5.4-mg/kg dose demonstrated a more favorable benefit-risk profile, including lower adjudicated drug-related interstitial lung disease incidence.

IDH-Wildtype With FGFR Gene Family Alterations en-subtitle= kn-subtitle= en-abstract= kn-abstract=Glioblastoma, isocitrate dehydrogenase wildtype (GBM, IDH-wt), is a highly aggressive brain tumor with a poor prognosis. Alterations in the fibroblast growth factor receptor (FGFR) gene family?such as FGFR::TACC fusions and FGFR1 mutations?have emerged as potential therapeutic targets; however, their clinical and genetic features in GBM, IDH-wt remain unclear. We analyzed 1076 GBM, IDH-wt cases using comprehensive genomic profiling data from the Center for Cancer Genomics and Advanced Therapeutics (C-CAT) database in Japan. FGFR alterations were detected in 8.0% of patients, including FGFR::TACC fusions (3.3%) and FGFR1 mutations (2.9%). The FGFR::TACC fusion-positive group was older at diagnosis and showed higher frequencies of TERT promoter mutation and MDM2 amplification, and lower frequencies of EGFR amplification and TP53 mutation, compared with the fusion-negative group. The FGFR1 mutation-positive group was enriched for ATRX, NF1, and PIK3CA mutations and had significantly fewer TERT promoter and PTEN mutations, compared with the mutation-negative group. No significant differences in overall survival were observed, although both groups tended to have longer median overall survival compared with their respective negative groups. This study represents the largest genomic cohort to date of FGFR alterations in GBM, IDH-wt. FGFR::TACC fusion-positive and FGFR1 mutation-positive GBMs exhibited distinct genetic profiles, highlighting the clinical relevance of molecular subclassification and providing insight for future therapeutic strategies. en-copyright= kn-copyright= en-aut-name=KegoyaYasuhito en-aut-sei=Kegoya en-aut-mei=Yasuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

の「理解・緩和・適応」の考え方をもとに観点を設け，記述を抽出・分類した。その結果，初等教育段階の「The World Around Us」では生活世界に根ざした環境配慮の態度と行動の基礎形成が重視され，前期中等教育段階の「Science」では科学的な因果関係や気候変動対策の国際的枠組みが導入されており段階的深化が確認された。一方で，概念導入の遅れ，因果連鎖の不統一，行動変容に至る仕組みの弱さ，学際性の不足や語彙や概念の習得のスパイラルな学習の不足が明らかになった。現行教科書は，体系的かつ実効的な気候変動教育には未だ不十分であり，今後の改善が求められることを指摘した。

kn-abstract=Some anaplastic lymphoma kinase (ALK) gene rearrangement?positive lung cancers show early resistance, within 3 months, to alectinib. This study investigated the clinical and molecular characteristics of these patients. We analyzed patients with unresectable stage III/IV disease without indications for radical radiotherapy and recurrent ALK-positive lung cancer who received alectinib as the primary ALK tyrosine kinase inhibitor between 2013 and 2021 at nine hospitals. In total, 103 patients were included. The median age was 65 years; 44 were male and 22 had brain metastases. The median progression-free survival and overall survival (OS) were 28.7 and 80.6 months. Nineteen patients treated for ?3 months and 84 treated for >3 months were categorized into the early resistance and responder groups, respectively. The early resistance group had significantly shorter OS (8.4 months vs. not estimable, P < 0.001) and was significantly more likely to have brain metastases (42% vs. 17%, P = 0.027). They also showed elevated inflammatory markers, including neutrophil-to-lymphocyte ratio (NLR). Univariate analysis identified brain metastases and high NLR as significant predictors of early resistance. Spatial transcriptome analysis and immunohistochemical staining revealed upregulation of annexin A1 (ANXA1), a calcium-dependent phospholipid-binding protein involved in inflammation and cancer progression, in the early resistance group. Interleukin 6 stimulation, prompted by elevated inflammatory markers, increased ANXA1 expression and reduced alectinib sensitivity. Knockdown of ANXA1 improved alectinib sensitivity in alectinib-resistant cells. In conclusion, brain metastases and high NLR are associated with early resistance. ANXA1 may play an important role in mediating early resistance. New treatment options for the early resistance group are required. en-copyright= kn-copyright= en-aut-name=KuribayashiTadahiro en-aut-sei=Kuribayashi en-aut-mei=Tadahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MakimotoGo en-aut-sei=Makimoto en-aut-mei=Go kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhashiKadoaki en-aut-sei=Ohashi en-aut-mei=Kadoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=InoueHirofumi en-aut-sei=Inoue en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YokoyamaToshihide en-aut-sei=Yokoyama en-aut-mei=Toshihide 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= en-aut-name=KatoYuka en-aut-sei=Kato en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KudoKenichiro en-aut-sei=Kudo en-aut-mei=Kenichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HoritaNaokatsu en-aut-sei=Horita en-aut-mei=Naokatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KayataniHiroe en-aut-sei=Kayatani en-aut-mei=Hiroe 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=SugimotoKeisuke en-aut-sei=Sugimoto en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=NinomiyaKiichiro en-aut-sei=Ninomiya en-aut-mei=Kiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 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=15 ORCID= en-aut-name=TogashiYosuke en-aut-sei=Togashi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 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=17 ORCID= affil-num=1 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Respiratory Medicine, Ohara Healthcare Foundation, Kurashiki Central Hospital kn-affil= affil-num=7 en-affil=Department of Respiratory Medicine, NHO Iwakuni Clinical Center kn-affil= affil-num=8 en-affil=Department of Thoracic Oncology and Medicine, National Hospital Organization, Shikoku Cancer Center kn-affil= affil-num=9 en-affil=Department of Respiratory Medicine, National Hospital Organization Okayama Medical Center kn-affil= affil-num=10 en-affil=Department of Respiratory Medicine, Kure Kyosai Hospital kn-affil= affil-num=11 en-affil=Department of Respiratory Medicine, Japanese Red Cross Okayama Hospital kn-affil= affil-num=12 en-affil=Department of Chest Surgery, Shimonoseki City Hospital kn-affil= affil-num=13 en-affil=Department of Respiratory Medicine, Japanese Red Cross Kobe Hospital kn-affil= affil-num=14 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=15 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=16 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=17 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260213 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Distinct associations of blood pressure phenotypes with subclinical cerebrovascular disease and coronary artery calcification in Japanese men en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hypertension, encompassing white-coat hypertension (WCH), masked hypertension (MH), and sustained hypertension (SH), is an established risk factor for cardiovascular diseases (CVDs), including atherosclerosis.

They also underwent office blood pressure (BP) measurements, home BP monitoring for at least five consecutive days, and coronary artery calcification (CAC) assessments between 2010 and 2014. The final analysis included 686 participants without a history of CVDs. Of the 686 participants, the mean age (?±?SD) was 68.0 (?±?8.3) years, and 39.3% were taking antihypertensive medication. In multivariable-adjusted models, each of WCH, MH, and SH was significantly associated with a higher risk of microbleeds compared to normotension. However, the association of WCH with microbleeds was evident only among those on antihypertensive medication (adjusted odds ratio [OR] 6.75 [95% CI 1.83?24.86]) and absent in those not on such medication (adjusted OR 1.20 [95% CI 0.31?4.73]). SH was associated with lacunar infarction, ICAS, and CAC. Among Japanese men, WCH, MH, SH were associated with subclinical cerebrovascular diseases, whereas only SH was associated with CAC. Moreover, any elevated BP phenotype increased the risk of microbleeds. Our findings suggest that different hypertension phenotypes distinctly affect target organs, particularly the brain and heart. en-copyright= kn-copyright= en-aut-name=BayaraaNomin en-aut-sei=Bayaraa en-aut-mei=Nomin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YanoYuichiro en-aut-sei=Yano en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KadotaAya en-aut-sei=Kadota en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AzaharNazar Mohd en-aut-sei=Azahar en-aut-mei=Nazar Mohd kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=PhapTran Ngoc Hoang en-aut-sei=Phap en-aut-mei=Tran Ngoc Hoang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=KondoKeiko en-aut-sei=Kondo en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ToriiSayuki en-aut-sei=Torii en-aut-mei=Sayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiyoshiAkira en-aut-sei=Fujiyoshi en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OhkuboTakayoshi en-aut-sei=Ohkubo en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ShiinoAkihiko en-aut-sei=Shiino en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NozakiKazuhiko en-aut-sei=Nozaki en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MiuraKatsuyuki en-aut-sei=Miura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=2 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=3 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=4 en-affil= kn-affil= affil-num=5 en-affil=National Institutes of Biomedical Innovation, Health and Nutrition kn-affil= affil-num=6 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=8 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=9 en-affil=Department of Hygiene, School of Medicine, Wakayama Medical University kn-affil= affil-num=10 en-affil=Department of Hygiene and Public Health, Teikyo University School of Medicine kn-affil= affil-num=11 en-affil=Molecular Neuroscience Research Center, Shiga University of Medical Science kn-affil= affil-num=12 en-affil=Department of Neurosurgery, Shiga University of Medical Science kn-affil= affil-num=13 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= en-keyword=Blood pressure phenotypes kn-keyword=Blood pressure phenotypes en-keyword=Morning hypertension kn-keyword=Morning hypertension en-keyword=Home blood pressure kn-keyword=Home blood pressure en-keyword=Subclinical cerebrovascular disease kn-keyword=Subclinical cerebrovascular disease en-keyword=Coronary artery calcification kn-keyword=Coronary artery calcification END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue= article-no= start-page=100540 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Flow diverter treatment for internal carotid artery aneurysm following management of distal cerebral aneurysms: Technical note en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: In recent years, the effectiveness of flow diverters (FDs) for the treatment of intracranial aneurysms has been reported. While FDs are effective, their deployment involves advancing a delivery wire distally, which may pose a risk if a distal aneurysm exists within the same artery. In such cases, the delivery wire could potentially perforate the distal aneurysm. Here, we present two cases of tandem aneurysms in which an internal carotid artery (ICA) aneurysm was treated with an FD following the treatment of a distal cerebral aneurysm.
Case description: A 44-year-old woman and a 67-year-old woman underwent magnetic resonance imaging for headache or abducens nerve palsy. In both cases, two aneurysms were revealed: one at the ICA and the other either at the middle cerebral artery or the top of the ICA. Due to the risk of perforation by the delivery wire during FD deployment, the distal aneurysms were treated first?either with surgical neck clipping or stent-assisted coil embolization. One month after the initial treatment, FD placement for the ICA aneurysm was performed as planned without complications in either case.
Discussion: This is the first report where tandem aneurysms were successfully treated with treatment for distal cerebral aneurysms, followed by FDs for proximal ICA aneurysms. We emphasize the potential risk of perforation of the distal aneurysm by the delivery wire during FD placement.
Conclusion: Treatment of distal cerebral aneurysms beforehand can help ensure the safe and effective use of FDs in patients with tandem aneurysms. en-copyright= kn-copyright= en-aut-name=HirataYuichi en-aut-sei=Hirata en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiramatsuMasafumi en-aut-sei=Hiramatsu en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugiuKenji en-aut-sei=Sugiu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BabaFukiko en-aut-sei=Baba en-aut-mei=Fukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujitaJuntaro en-aut-sei=Fujita en-aut-mei=Juntaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SotomeYuta en-aut-sei=Sotome en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawakamiMasato en-aut-sei=Kawakami en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KimuraRyu en-aut-sei=Kimura en-aut-mei=Ryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=EbisudaniYuki en-aut-sei=Ebisudani en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HarumaJun en-aut-sei=Haruma en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HishikawaTomohito en-aut-sei=Hishikawa en-aut-mei=Tomohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TanakaShota en-aut-sei=Tanaka en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Neurosurgery, Kawasaki Medical School 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=Flow diverter kn-keyword=Flow diverter en-keyword=Tandem aneurysms kn-keyword=Tandem aneurysms en-keyword=Complication kn-keyword=Complication en-keyword=Perforation kn-keyword=Perforation en-keyword=Delivery wire kn-keyword=Delivery wire END start-ver=1.4 cd-journal=joma no-vol=47 cd-vols= no-issue=6 article-no= start-page=410 end-page=412 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=Transbrachial artery approach with an ultra-long sheath in intraoperative angiography for craniocervical junction arteriovenous fistula kn-title=頭蓋頚椎移行部動静脈瘻の開頭手術時における上腕動脈穿刺による脳血管撮影の有用性 en-subtitle= kn-subtitle= en-abstract=In surgery for craniocervical junction-arteriovenous fistula (CCJ-AVF), intraoperative angiography is often required to identify the abnormal vessels. However, conventional intraoperative angiography poses challenges related to sheath fixation and catheter manipulation. In this study, we present a novel method for intraoperative angiography for CCJ-AVF using an ultra-long sheath inserted via the brachial artery and positioned at the subclavian artery to perform vertebral artery angiography (VAG). We evaluated patient demographics and complications in cases where this angiography method was employed. VAG was successfully performed in all four intended cases, and no complications were observed. This method enables us to change patient positions easily and provides a clear visualization of the puncture site. The catheter is also simply manipulated, allowing us to perform VAG with ease. Furthermore, there is no concern about the interference between the C-arm and the surgical field. This angiography method appears to be effective. kn-abstract=頭蓋頚椎移行部動静脈瘻の手術では，異常血管の確認のため術中血管撮影が重要であるが，体位変換時のsheathの固定や撮影血管へのカテーテルの誘導が困難である．今回，頭蓋頚椎移行部動静脈瘻の開頭手術において上腕動脈穿刺によりultra-long

(GI-1Pta6605) has been identified as a pathogenicity island required for virulence because the deletion almost completely eliminated disease symptoms in inoculation tests at 4?×?105 CFU/ml. GI-1Pta6605 contains four cargo regions (CRs) named CR-1 to CR-4. The ?CR-4 mutant did not produce tabtoxin like ?GI-1 and disease symptoms did not develop in tobacco. However, it grew, although to a lesser extent than the wild-type strain. These results indicate that the tabtoxin biosynthetic gene cluster in GI-1 is required for virulence but not for establishment of compatibility. en-copyright= kn-copyright= en-aut-name=KunishiKotomi en-aut-sei=Kunishi en-aut-mei=Kotomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujisawaNorika en-aut-sei=Fujisawa en-aut-mei=Norika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=SakataNanami en-aut-sei=Sakata en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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=7 ORCID= affil-num=1 en-affil=The Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=The Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=The Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=The Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=The Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=The Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=The Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=GI-1Pta6605 kn-keyword=GI-1Pta6605 en-keyword=Pathogenicity island kn-keyword=Pathogenicity island en-keyword=Pseudomonas syringae kn-keyword=Pseudomonas syringae en-keyword=Tabtoxin kn-keyword=Tabtoxin END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=3 article-no= start-page=e105012 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Rare Association of Congenital Glaucoma and Retinitis Pigmentosa: A 22-Year Follow-Up Case en-subtitle= kn-subtitle= en-abstract= kn-abstract=Primary congenital glaucoma is a rare congenital disease with a genetic background that shows high intraocular pressure due to ocular outflow anomalies. Retinitis pigmentosa is a predominant form of inherited retinal disorders. In this study, we present the case of a patient with primary congenital glaucoma in association with retinitis pigmentosa. A four-month-old female baby was brought to the emergency department due to corneal opacity in the left eye. The intraocular pressure measured by a hand-held applanation tonometer was 40 mmHg in the right eye and 36 mmHg in the left eye. She was otherwise healthy and diagnosed with primary congenital glaucoma. She immediately underwent trabeculotomy ab externo in both eyes under general anesthesia, and the intraocular pressure was lowered to 15 mmHg in the right eye and 12 mmHg in the left eye three weeks later. At the age of nine months, she was found to have retinal degeneration along the upper and lower vascular arcades of the fundus in both eyes and was diagnosed with retinitis pigmentosa. At the age of one year and 10 months, the visual acuity was measured at 0.2 in the right eye and 0.2 in the left eye for the first time by a preferential looking procedure. The intraocular pressure was 9 mmHg in both eyes under sedation, and she did not use any topical medication. At the age of three years and three months, the uncorrected visual acuity and best-corrected visual acuity with myopic astigmatism correction were 0.1 and 0.15, respectively, in the right eye and 0.6 and 0.7, respectively, in the left eye. Occlusion therapy with an eye patch over the left eye for one hour daily was started. At the age of four years and 10 months, the best-corrected visual acuity was 0.7 in both eyes. At the age of six years, occlusion therapy was discontinued, and full-correction glasses were prescribed, based on cycloplegic refraction. The visual acuity in the right eye decreased to 0.3 at the age of 11 years and further to 0.1 at the age of 12 years, while the visual acuity in the left eye remained 0.8. Afterwards, she maintained a visual acuity of 0.1 in the right eye and 0.8 in the left eye until the age of 22 years. An incidental presence of primary congenital glaucoma in this patient led to the detection of retinitis pigmentosa in earlier years and allowed long-term follow-up for 22 years. Even though genetic testing was not performed for this patient, the abnormal function of primary cilia, designated as ciliopathy, might explain the co-occurrence of primary congenital glaucoma and retinitis pigmentosa. 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= affil-num=1 en-affil=Ophthalmology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=ciliopathy kn-keyword=ciliopathy en-keyword=cycloplegic refraction kn-keyword=cycloplegic refraction en-keyword=full-correction glasses kn-keyword=full-correction glasses en-keyword=goldmann perimetry kn-keyword=goldmann perimetry en-keyword=occlusion therapy kn-keyword=occlusion therapy en-keyword=optical coherence tomography kn-keyword=optical coherence tomography en-keyword=photoreceptor ellipsoid zone kn-keyword=photoreceptor ellipsoid zone en-keyword=primary congenital glaucoma kn-keyword=primary congenital glaucoma en-keyword=retinitis pigmentosa kn-keyword=retinitis pigmentosa en-keyword=trabeculotomy kn-keyword=trabeculotomy END start-ver=1.4 cd-journal=joma no-vol=94 cd-vols= no-issue=4 article-no= start-page=522 end-page=529 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=Effects of Intermittent Low-temperature Storage Duration and Cycle on the Bolting and Flowering of Delphinium elatum in Summer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Early-bolting in summer is a major problem when growing delphinium seedlings in summer to produce cut flowers that will be shipped in autumn and winter. In this study, an intermittent low-temperature storage (ILTS) treatment that induces flower bud differentiation in strawberry and prevents rosette formation in Eustoma significantly increased the Delphinium elatum cut flower length. Moreover, ILTS was as effective as growing seedlings under cool conditions at preventing early-bolting. We analyzed the effects of six ILTS treatments that differed regarding the treatment temperature (5 and 10°C) and treatment cycle (3 days/3 days, 6 days/6 days, and 12 days/12 days; ambient conditions/cool and dark). Cut flowers were significantly longer with the 6 days/6 days treatment at 10°C than for the control treatment. Furthermore, repeating the ILTS treatment cycle (6 days ambient conditions/6 days at 10°C) a total of four times produced high-quality cut flowers regardless of the cultivar. Therefore, this ILTS treatment may be ideal for preventing early-bolting in D. elatum. en-copyright= kn-copyright= en-aut-name=KawaiMika en-aut-sei=Kawai en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukuyasuMiwa en-aut-sei=Fukuyasu en-aut-mei=Miwa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaYoshiyuki en-aut-sei=Tanaka en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KitamuraYoshikuni en-aut-sei=Kitamura en-aut-mei=Yoshikuni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YasubaKen-ichiro en-aut-sei=Yasuba en-aut-mei=Ken-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshidaYuichi en-aut-sei=Yoshida en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=GotoTanjuro en-aut-sei=Goto en-aut-mei=Tanjuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=cool storage kn-keyword=cool storage en-keyword=cut flower quality kn-keyword=cut flower quality en-keyword=high ambient temperature kn-keyword=high ambient temperature en-keyword=long day kn-keyword=long day en-keyword=Ranunculaceae kn-keyword=Ranunculaceae END start-ver=1.4 cd-journal=joma no-vol=95 cd-vols= no-issue=1 article-no= start-page=10 end-page=20 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparison of Fruit Development, Ripening, and Transcriptome Dynamics in Taiwanese and Japanese Cultivars of Japanese Apricot (Prunus mume Sieb. et Zucc.) en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, we compared changes in traits associated with fruit development and ripening in Taiwanese and Japanese cultivars of Japanese apricot (Prunus mume Sieb. et Zucc.). We also analyzed transcriptome profiles to comprehensively examine different fruit development and ripening patterns between the two groups in terms of fruit characteristics and gene expression. Early fruit development in Taiwanese cultivars ‘ST’ and ‘Ellching’ and the Japanese cultivar ‘Hakuo’ was ahead of that in other three Japanese cultivars (P1). From late April to early May, around the stone-hardening stage, the developmental differences decreased to the same level. Thereafter, Japanese cultivars showed rapid growth, whereas Taiwanese cultivars showed slower growth, reversing the developmental differences between these lines (P2). Ethylene production was not detected until the full ripening stage and was detected for the first time at this stage in five cultivars, except for ‘Ellching’ (P3). In contrast, no ethylene production was observed during the entire duration of fruit development in ‘Ellching’. A multidimensional scaling plot showed that the overall transcriptome profile changed according to the three stages (P1?P3) of fruit development and ripening. At P1, gene ontologies (GOs) related to cell division, such as the cell cycle and regulation of cyclin-dependent protein serine/threonine kinase activity, were enriched for differentially expressed genes downregulated in Taiwanese cultivars as compared with their expression in Japanese cultivars. At P2, GOs related to fruit development were not enriched, but some genes related to phytohormones, such as auxin, abscisic acid, and cytokinin, which are associated with fruit development and ripening, were differentially expressed. At P3, the expression of genes such as ACS, ACO, and PG, which are involved in ethylene biosynthesis, increased in response to increased ethylene production, but not in ‘Ellching’, which showed no ethylene production. Expression analysis of 115 NAC (NAM-ATAF1/2-CUC2) family genes, which are related to fruit ripening and ripening date in other fruit species, in the ‘Ellching’ genome revealed changes in expression of NAC056 and NAC073 corresponding to fruit development and ripening in Taiwanese and Japanese cultivars. We discuss the differences in fruit development and ripening behaviors between Taiwanese and Japanese cultivars in terms of physiological and transcriptome changes. en-copyright= kn-copyright= en-aut-name=KashiwamotoTomoaki en-aut-sei=Kashiwamoto en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawaiTakashi en-aut-sei=Kawai en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OeTakaaki en-aut-sei=Oe en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NumaguchiKoji en-aut-sei=Numaguchi en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KitamuraYuto en-aut-sei=Kitamura en-aut-mei=Yuto 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=FukudaFumio en-aut-sei=Fukuda en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=Japanese Apricot Laboratory, Wakayama Fruit Tree Experiment Station kn-affil= affil-num=4 en-affil=Japanese Apricot Laboratory, Wakayama Fruit Tree Experiment Station kn-affil= affil-num=5 en-affil=Faculty of Agriculture, Setsunan 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= affil-num=8 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=cell division kn-keyword=cell division en-keyword=ethylene production kn-keyword=ethylene production en-keyword=NAC kn-keyword=NAC en-keyword=phytohormone kn-keyword=phytohormone en-keyword=stone hardening kn-keyword=stone hardening END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=98 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260119 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genetic and phenotypic identities of Staphylococcus coagulans isolated from pustules of dogs with superficial bacterial folliculitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Staphylococcus coagulans, formerly called Staphylococcus schleiferi subsp. coagulans is the second most common isolate from skin lesions of dogs with superficial bacterial folliculitis (SBF). However, the clinical significance of S. coagulans in pustules of canine SBF remains uncertain. This study aimed to investigate the prevalence and genotypic and phenotypic diversity of S. coagulans isolated from pustules in two dogs with SBF.
Results Two dogs with SBF were included in this study. S. schleiferi/coagulans was isolated as the sole organism from three pustules in case #1, whereas it coexisted with S. pseudintermedius in two of seven pustules in case #2. S. pseudintermedius was the sole organism in the remaining five pustules in case #2. Whole genome sequences revealed that all isolates tested were annotated as S. coagulans. The isolates from the same pustules exhibited identical genotypic and phenotypic profiles, indicating clonal multiplication. S. coagulans isolated from different pustules exhibited similar yet distinct genotypic and phenotypic profiles.
Conclusions S. coagulans with identical genetic and phenotypic profiles can be identified as the sole pathogen or coexist with S. pseudintermedius in the pustules of the same dogs with SBF. en-copyright= kn-copyright= en-aut-name=OsumiTakafumi en-aut-sei=Osumi en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShinomiyaYuuki en-aut-sei=Shinomiya en-aut-mei=Yuuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WanganuttaraThamonwan en-aut-sei=Wanganuttara en-aut-mei=Thamonwan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ImanishiIchiro en-aut-sei=Imanishi en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShimazakiYotaro en-aut-sei=Shimazaki en-aut-mei=Yotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IyoriKeita en-aut-sei=Iyori en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ToyodaYoichi en-aut-sei=Toyoda en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IdeKaori en-aut-sei=Ide en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UchiyamaJumpei en-aut-sei=Uchiyama en-aut-mei=Jumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NishifujiKoji en-aut-sei=Nishifuji en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Animal Medical Center, Faculty of Agriculture, Tokyo University of Agriculture and Technology kn-affil= affil-num=2 en-affil=Department of Veterinary Medicine, Faculty of Agriculture, Tokyo University of Agriculture and Technology kn-affil= affil-num=3 en-affil=Department of Bacteriology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Kimberly and Eric J.

Its guanidine moiety, while essential for NET binding, presents major radiosynthetic challenges due to high basicity and the harsh deprotection conditions required for protected precursors. Previous methods relied on multistep procedures, strong acids, and complex purification, limiting clinical translation. This study aimed to develop a practical one-step radiosynthesis suitable for routine and automated production. Methods: A direct SN2-type nucleophilic [18F]fluorination was performed using an unprotected guanidine precursor to eliminate deprotection steps. Reaction parameters, including the base system, solvent composition, precursor concentration, and temperature, were optimized under conventional and microwave heating. Radiochemical conversion (RCC) and operational robustness were evaluated, and purification strategies were assessed for automation compatibility. Results: Direct [18F]fluorination using the unprotected precursor reduced the total synthesis time to 60?70 min. Optimal conditions employed a tert-butanol/acetonitrile (4:1) solvent system with K2CO3/Kryptofix222, affording RCC up to 33% under conventional heating. Microwave irradiation further improved efficiency, achieving RCC of up to 64% within 1.5 min at 140 °C. The method showed broad tolerance to variations in the base molar ratio and precursor concentration and enabled isocratic HPLC purification. Conclusions: This one-step radiosynthesis overcomes longstanding challenges in [18F]fluproxadine production by eliminating harsh deprotection and enabling high-yield, automation-ready synthesis, thereby improving clinical feasibility. en-copyright= kn-copyright= en-aut-name=ChenXinyu en-aut-sei=Chen en-aut-mei=Xinyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhtaKaito en-aut-sei=Ohta en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KimuraHiroyuki en-aut-sei=Kimura en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YagiYusuke en-aut-sei=Yagi en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SasakiTakanori en-aut-sei=Sasaki en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NoseNaoko en-aut-sei=Nose en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AkehiMasaru en-aut-sei=Akehi en-aut-mei=Masaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamaneTomohiko en-aut-sei=Yamane en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=WernerRudolf A. en-aut-sei=Werner en-aut-mei=Rudolf A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HiguchiTakahiro en-aut-sei=Higuchi en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Nuclear Medicine, Faculty of Medicine, University of Augsburg kn-affil= affil-num=2 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Agency for Health, Safety and Environment, Kyoto University kn-affil= affil-num=4 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Molecular Imaging Research, Kobe City Medical Center General Hospital kn-affil= affil-num=9 en-affil=Department of Nuclear Medicine, LMU Hospital, and German Cancer Consortium (DKTK), Partner Site Munich, Ludwig-Maximilians-University of Munich kn-affil= affil-num=10 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=norepinephrine transporter kn-keyword=norepinephrine transporter en-keyword=positron emission tomography kn-keyword=positron emission tomography en-keyword=[18F]AF78 kn-keyword=[18F]AF78 en-keyword=[18F]fluproxadine kn-keyword=[18F]fluproxadine en-keyword=radiolabeling kn-keyword=radiolabeling END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=5 article-no= start-page=2113 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fgf10 Gene Dosage from a Single Allele Is Insufficient for Forming Multilayered Epithelial Cells in the Murine Lacrimal Gland en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mutations in the fibroblast growth factor 10 (FGF10) gene in humans cause aplasia of the lacrimal and salivary glands (ALSG). In patients with ALSG, heterozygous loss-of-function mutations are found, and FGF10 haploinsufficiency results in the absence of these secretory organs. Lacrimal glands (LGs) are formed through epithelial thickening, budding, and branching morphogenesis. To compare the variable phenotypes of the Fgf10+/? Harderian glands (HGs) previously reported, we examined the development of LGs in wild-type (WT), Fgf10+/?, and Fgf10-null mice. Pax6 immunostaining was performed to visualize the LG primordia from embryonic day 15.5 (E15.5) onwards. In situ hybridization of the genes encoding the epithelial receptor of FGF10, FGFR2b, and its other ligands was performed to determine their potential involvement in LG development. LG primordia were not observed in Fgf10+/? mice bilaterally at E16.5 or later stages. At E15.5, budding from the developing conjunctival epithelium (CE) was observed in a small fraction of the Fgf10+/? LG primordia. In contrast, the Fgf10-null CE failed to promote budding. Among Fgf1, Fgf3, Fgf7, Fgf10, and Fgf22, Fgf10 was expressed in the mesenchyme surrounding developing LG epithelial cells, whereas Fgf1 was expressed in the LG epithelium of WT mice. Fgf7 was initially expressed in the mesenchyme surrounding the nascent LG epithelium, but its expression subsequently became diffused. Thus, we conclude that among the FGFR2b ligands, initial LG formation is dependent on the mesenchymal factors FGF10 and FGF7, and FGF1 is likely to function as an epithelial factor in the LG primordia. A single allele of Fgf10 was found to be insufficient to support the budding process during LG morphogenesis. en-copyright= kn-copyright= en-aut-name=IkedaShiori en-aut-sei=Ikeda en-aut-mei=Shiori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoKeita en-aut-sei=Sato en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TajikaYuki en-aut-sei=Tajika en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujitaHirofumi en-aut-sei=Fujita en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BandoTetsuya en-aut-sei=Bando en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NohnoTsutomu en-aut-sei=Nohno en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyaishiSatoru en-aut-sei=Miyaishi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OhuchiHideyo en-aut-sei=Ohuchi en-aut-mei=Hideyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Gumma Prefectural College of Health Sciences kn-affil= affil-num=4 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Legal Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=fibroblast growth factor kn-keyword=fibroblast growth factor en-keyword=Fgf10 kn-keyword=Fgf10 en-keyword=Fgf1 kn-keyword=Fgf1 en-keyword=Fgf3 kn-keyword=Fgf3 en-keyword=Fgf7 kn-keyword=Fgf7 en-keyword=Fgf22 kn-keyword=Fgf22 en-keyword=Fgfr2b kn-keyword=Fgfr2b en-keyword=mouse kn-keyword=mouse en-keyword=lacrimal gland kn-keyword=lacrimal gland en-keyword=development kn-keyword=development END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=1716939 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structural analysis of PSI-ACPI and PSII-ACPII supercomplexes from a cryptophyte alga Rhodomonas sp. NIES-2332 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Light energy is converted to chemical energy by two photosystems (PSI and PSII) in complex with their light-harvesting complex proteins (LHCI and LHCII) in photosynthesis. Rhodomonas is a member of cryptophyte alga whose LHCs contain unique chlorophyll a/c proteins (ACPs) and phycobiliproteins. We purified PSI-ACPI and PSII-ACPII supercomplexes from a cryptophyte Rhodomonas sp. NIES-2332 and analyzed their structures at high resolutions of 2.08 ? and 2.17 ?, respectively, using cryo-electron microscopy. These structures are largely similar to those reported previously from two other species of cryptophytes, but exhibited some differences in both the pigment locations and subunit structures. A part of the antenna subunits of both photosystems is shifted compared with the previously reported structures from other species of cryptophytes, suggesting some differences in the energy transfer rates from the antenna to the PSI and PSII cores. Newly identified lipids are found to occupy the interfaces between the antennae and cores, which may be important for assembly and stabilization of the supercomplexes. Water molecules surrounding three iron-sulfur clusters of the PSI core are found in our high-resolution structure, some of which are conserved from cyanobacteria to higher plants but some are different. In addition, our structure of PSII-ACPII lacks the subunits of oxygen-evolving complex as well as the Mn4CaO5 cluster, suggesting that the cells are in the S-growth phase, yet the PSI-ACPI structure showed the binding of PsaQ, suggesting that it is in an L-phase. These results suggest that the S-phase and L-phase can co-exist in the cryptophytic cells. The high-resolution structures of both PSI-ACPIs and PSII-ACPIIs solved in this study provide a more solid structural basis for elucidating the energy transfer and quenching mechanisms in this group of the organisms. en-copyright= kn-copyright= en-aut-name=ZhangWenyue en-aut-sei=Zhang en-aut-mei=Wenyue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoneharaNozomi en-aut-sei=Yonehara en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshiiMizuki en-aut-sei=Ishii en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=JiangHaowei en-aut-sei=Jiang en-aut-mei=Haowei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=La RoccaRomain en-aut-sei=La Rocca en-aut-mei=Romain kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsaiPi-Cheng en-aut-sei=Tsai en-aut-mei=Pi-Cheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=LiHongjie en-aut-sei=Li en-aut-mei=Hongjie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KatoKoji en-aut-sei=Kato en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AkitaFusamichi en-aut-sei=Akita en-aut-mei=Fusamichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= affil-num=1 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=10 en-affil=Advanced Research Field, Research Institute for Interdisciplinary Science, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=cryptophytes kn-keyword=cryptophytes en-keyword=Rhodomonas kn-keyword=Rhodomonas en-keyword=photosystem I kn-keyword=photosystem I en-keyword=photosystem II kn-keyword=photosystem II en-keyword=light-harvesting complex kn-keyword=light-harvesting complex en-keyword=photosynthesis kn-keyword=photosynthesis END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=13 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pan-cancer profiling links C1orf50 to DNA repair and immune modulation in ovarian cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background C1orf50 encodes a small, evolutionarily conserved protein, the function of which remains unclear. Its significance across various human cancers, particularly its specific role in ovarian cancer within an immunogenomic context, is not yet fully understood. Utilizing The Cancer Genome Atlas and single-cell RNA sequencing (scRNA-seq) public datasets, we conducted a comprehensive profiling of C1orf50 across multiple cancer types, with a particular focus on ovarian cancer, to investigate its associations with copy-number status, genomic instability, tumor programs, and the immune microenvironment.
Results Across cancer types, copy-number gain or amplification of C1orf50 was most frequent in ovarian cancer and closely tracked with higher messenger RNA levels. Higher C1orf50 expression was associated with a greater tumor mutational burden and homologous recombination deficiency, as indicated by gene-set patterns that suggested heightened cell-cycle and cellular stress responses accompanied by reduced oxidative phosphorylation, enrichment of regulatory T cells, and depletion of resting memory CD4 T cells. In ovarian cancer, focal events at chromosome 1p34.2 were accompanied by stepwise increases in C1orf50 expression by clinical stage and were linked to higher tumor mutational burden, homologous recombination deficiency, and greater loss of heterozygosity, together with more frequent gene alterations in BRCA1 or BRCA2. Immune composition clustered into profiles consistent with an immunosuppressive context in tumors with higher C1orf50 expression. The scRNA-seq data further revealed that cancer cells enhanced immune-suppressive interactions with various immune cell populations and diminished antigen-presentation signals. Analyses of genomic instability in ovarian cancer suggested mutational processes compatible with base-substitution patterns associated with cytidine deaminase activity and with insertion-deletion patterns characteristic of homologous recombination failure, while transcript-level patterns pointed to a broad downshift of canonical DNA repair activity with apparent compensatory adjustments in related pathways rather than a uniform change in any single pathway.
Conclusions The overexpression of C1orf50 characterizes an aggressive immunogenomic phenotype in ovarian cancer, distinguished by genomic instability, impaired DNA repair mechanisms, and extensive immunosuppression. These findings indicate that C1orf50 warrants consideration as a potential biomarker and a prospective target for therapeutic investigation. Furthermore, they advocate for the progression to prospective validation and functional studies to ascertain its clinical significance. en-copyright= kn-copyright= en-aut-name=RogachevskayaAnna en-aut-sei=Rogachevskaya en-aut-mei=Anna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtaniYusuke en-aut-sei=Otani en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhtsuAkira en-aut-sei=Ohtsu en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChinVanessa D. en-aut-sei=Chin en-aut-mei=Vanessa D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Pe?aTirso en-aut-sei=Pe?a en-aut-mei=Tirso kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AraiSeiji en-aut-sei=Arai en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=FujimuraAtsushi en-aut-sei=Fujimura en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaAtsushi en-aut-sei=Tanaka en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Harvard Medical School kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Harvard Medical School kn-affil= affil-num=4 en-affil=UMass Chan Medical School, UMass Memorial Medical Center kn-affil= affil-num=5 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Harvard Medical School kn-affil= affil-num=6 en-affil=Department of Urology, Gunma University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Molecular Physiology, Faculty of Medicine, Graduate School of Medicine, Kagawa University kn-affil= affil-num=9 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Harvard Medical School kn-affil= en-keyword=C1orf50 kn-keyword=C1orf50 en-keyword=Pan-cancer analysis kn-keyword=Pan-cancer analysis en-keyword=DNA repair kn-keyword=DNA repair en-keyword=Gene expression kn-keyword=Gene expression en-keyword=Tumor microenvironment kn-keyword=Tumor microenvironment en-keyword=Immune evasion kn-keyword=Immune evasion en-keyword=Single-cell RNA-seq kn-keyword=Single-cell RNA-seq END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260124 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=TeMPRA: advancing continuing professional development in pediatric rheumatology in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background In the context of the global shortage of pediatric rheumatologists, mid-career specialists who can play key roles in regional education, research, and clinical practice have become increasingly important. In Japan, the Team of Mid-career Pediatric Rheumatologists Alliance (TeMPRA) was founded in 2014 to support continuing professional development (CPD) and foster collaboration among mid-career pediatric rheumatologists. The aim of this study was to characterize the current status and future perspectives of the TeMPRA members.
Methods In 2024, a cross-sectional, web-based survey was conducted among all 37 active members of the TeMPRA across Japan. Data were collected on career trajectories, educational roles, research activities, clinical practices, and international engagement. Categorical variables were compared using appropriate statistical tests, with a significance level of 0.05.
Results Responses were obtained from 35 members (response rate: 95%). Most respondents (71%) were affiliated with university hospitals, and 60% had?>?10 years of experience in pediatric rheumatology. Compared with those working in community hospitals, respondents affiliated with university hospitals were significantly more likely to be involved in research activities (50% vs. 0%, P?=?0.0261) and global professional contributions (88% vs. 0%, P? Conclusions This nationwide survey highlights the substantial educational roles, research activities, and clinical practices of mid-career pediatric rheumatologists in Japan and suggests that the TeMPRA framework can serve as a valuable model for supporting CPD and workforce sustainability. Similar alliance-based approaches may be applicable in other countries facing comparable challenges in pediatric rheumatology. en-copyright= kn-copyright= en-aut-name=WakiguchiHiroyuki

kn-title=Effects of systemic ventricular assist combined with fenestration in failing Fontan: A theoretical analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Biventricular assist for failing Fontan circulation remains challenging. Because fenestration effectively reduces stressed blood volume and central venous pressure in Fontan patients with increased pulmonary vascular resistance (PVR), systemic ventricular assist device (VAD) combined with fenestration may improve hemodynamics in failing Fontan patients with increased PVR who would require biventricular assist. To validate this hypothesis, we performed a computational hemodynamic simulation of the failing Fontan circulation using a lumped parameter model. We compared hemodynamic variables between the models with and without fenestration while the PVR index was increased sequentially from 3.01 to 6.81 Wood Units m2. Following VAD initiation and stressed blood volume reduction, central venous pressure was maintained at a lower level in the fenestration models. This positive effect was greater in the model with larger fenestration diameter. However, excessive fenestration caused significant desaturation. In failing Fontan circulation with elevated PVR, systemic VAD combined with fenestration significantly improved hemodynamics. en-copyright= kn-copyright= en-aut-name=ShimizuShuji en-aut-sei=Shimizu en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KotaniYasuhiro en-aut-sei=Kotani en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HorioNaohiro en-aut-sei=Horio en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KisamoriEiri en-aut-sei=Kisamori en-aut-mei=Eiri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyaharaYoshinori en-aut-sei=Miyahara en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UemuraKoji en-aut-sei=Uemura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShishidoToshiaki en-aut-sei=Shishido en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=5 en-affil=Pediatric Heart Disease and Adult Congenital Heart Disease Center, Showa Medical University Hospital kn-affil= affil-num=6 en-affil=Department of Research Promotion and Management, National Cerebral and Cardiovascular Center kn-affil= affil-num=7 en-affil=Department of Research Promotion and Management, National Cerebral and Cardiovascular Center kn-affil= affil-num=8 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= en-keyword=Fontan circulation kn-keyword=Fontan circulation en-keyword=Hemodynamic simulation kn-keyword=Hemodynamic simulation en-keyword=Ventricular assist device kn-keyword=Ventricular assist device en-keyword=Fenestration kn-keyword=Fenestration en-keyword=Pulmonary vascular resistance kn-keyword=Pulmonary vascular resistance END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=5 article-no= start-page=e2025GL119568 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electrical Conductivity of Amorphous and Molten CaCO3 at High Pressures and Its Implications for Mantle Conductivity Anomalies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Impedance spectrometry experiments have been conducted on CaCO3 up to 15 GPa and 2,100 K to identify its state under high pressure. The melting temperature of CaCO3 was also determined by the falling of a Re sphere observed via X-ray radiography. The phase transition from aragonite to the amorphous phase does not cause a leap in the Electrical conductivity (EC), while a drastic increase in the EC, by 1.5?2.0 log units, only occurs with the onset of melting. The EC of amorphous CaCO3 is comparable to other hydrous mantle minerals at similar pressure and temperature conditions. The required fraction of amorphous CaCO3 implies that it can be excluded from the potential origins responsible for the observed high EC anomalies in the upper mantle. If the conductivity anomalies are induced by the presence of carbonate, a low-degree melting of carbonate-bearing peridotite is anticipated. en-copyright= kn-copyright= en-aut-name=ZhaoBin en-aut-sei=Zhao en-aut-mei=Bin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshinoTakashi en-aut-sei=Yoshino en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ChenQi en-aut-sei=Chen en-aut-mei=Qi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YuTony en-aut-sei=Yu en-aut-mei=Tony kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ZhangDongzhou en-aut-sei=Zhang en-aut-mei=Dongzhou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ChenBin en-aut-sei=Chen en-aut-mei=Bin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WangYanbin en-aut-sei=Wang en-aut-mei=Yanbin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=Center for Advanced Radiation Sources, The University of Chicago kn-affil= affil-num=4 en-affil=Center for Advanced Radiation Sources, The University of Chicago kn-affil= affil-num=5 en-affil=Center for Advanced Radiation Sources, The University of Chicago kn-affil= affil-num=6 en-affil=School of Ocean and Earth Science and Technology, University of Hawaii at Manoa kn-affil= affil-num=7 en-affil=Center for Advanced Radiation Sources, The University of Chicago kn-affil= END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue= article-no= start-page=47 end-page=60 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Ultrafast Time-Compressive CMOS Image Sensors Based on Multitap Charge Modulators for Filming Light-In Flight en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ultrafast time-compressive CMOS image sensors based on multitap charge modulators can capture light-in flight using coded exposure masks on the focal plane. Transient images can then be reconstructed using iterative methods or deep learning models. Although the image sensor is based on indirect time-of-flight (ToF) image sensors, the reconstructed images are equivalent to those captured by direct ToF (D-ToF) image sensors. Important design parameters of the image sensor include the pixel block size and the number of taps of the charge modulator. Several constraints regarding the charge transfer of the multitap charge modulator, the hamming distance between exposure codes at adjacent timings, and the minimal time window duration must be considered when designing exposure codes. The influence of these factors on the fidelity of the reconstructed images is analyzed numerically. The results show that a pixel block size of 4×4 is optimal and that four or more taps are required for light detection and ranging (LiDAR) applications when 32 transient images of light-in flight are reconstructed. To demonstrate LiDAR in a scene with multipath interference, two objects were observed through a weakly diffusive sheet. The temporal resolution, as defined by the clock period of the exposure codes, was 1.65 ns. Multiple reflections were reconstructed using an iterative method (TVAL3) and a deep learning model (ADMM-Net). Although the waveforms of optical pulses reconstructed by TVAL3 are distorted, the amplitudes are more accurate. Conversely, although ADMM-Net reconstructs sharper optical pulses, the amplitudes are inaccurate. To achieve the shorter temporal resolution required for time-resolved diffuse optical tomography (DOT) and fluorescence lifetime imaging (FLIm), the feasibility of heterodyne compression was demonstrated through simulation. en-copyright= kn-copyright= en-aut-name=KagawaKeiichiro en-aut-sei=Kagawa en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayashiDaisuke en-aut-sei=Hayashi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakakuraArashi en-aut-sei=Takakura en-aut-mei=Arashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UmekiYuto en-aut-sei=Umeki en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshidaMichitaka en-aut-sei=Yoshida en-aut-mei=Michitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YasutomiKeita en-aut-sei=Yasutomi en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawahitoShoji en-aut-sei=Kawahito en-aut-mei=Shoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ChaeYoungcheol en-aut-sei=Chae en-aut-mei=Youngcheol kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NagaharaHajime en-aut-sei=Nagahara en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Research Institute of Electronics, Shizuoka University kn-affil= affil-num=2 en-affil=Graduate School of Integrated Science and Technology, Shizuoka University kn-affil= affil-num=3 en-affil=Faculty of Engineering, Shizuoka University kn-affil= affil-num=4 en-affil=Graduate School of Integrated Science and Technology, Shizuoka University kn-affil= affil-num=5 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Research Institute of Electronics, Shizuoka University kn-affil= affil-num=7 en-affil=Research Institute of Electronics, Shizuoka University kn-affil= affil-num=8 en-affil=Department of Electrical and Electronic Engineering, Yonsei University kn-affil= affil-num=9 en-affil=D3 Center, The University of Osaka kn-affil= en-keyword=CMOS image sensor kn-keyword=CMOS image sensor en-keyword=compressive imaging kn-keyword=compressive imaging en-keyword=computational photography (CP) kn-keyword=computational photography (CP) en-keyword=multitap charge modulator kn-keyword=multitap charge modulator en-keyword=transient imaging kn-keyword=transient imaging END start-ver=1.4 cd-journal=joma no-vol=410 cd-vols= no-issue=1 article-no= start-page=171 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Robotic distal pancreatectomy using two-surgeon technique (TAKUMI-4): a technical note and initial outcomes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose With the increasing use of minimally invasive distal pancreatectomy, the use of robotic distal pancreatectomy (RDP) is also increasing worldwide. Standardized surgical protocols are essential for safe implementation of RDP. In this study, we present our surgical protocol and initial outcomes of RDP using “two-surgeon technique”.
Methods Our standard RDP protocol included a two-surgeon technique for cooperation, rationality, and education. Short-term outcomes of RDP were also investigated. This retrospective study included 77 consecutive patients who underwent RDP at our institution between April 2021 and January 2025.
Results The median operative time, estimated blood loss, and postoperative hospital stay were 214 min (interquartile range [IQR], 176?253), 10 mL (IQR, 0?50), and 9 days (IQR, 8?10), respectively. A textbook outcome was achieved in 84.4% of patients. Moreover, superior outcomes of RDP (n?=?77) compared with those of laparoscopic distal pancreatectomy (n?=?62) were confirmed in this study.
Conclusion Using the two-surgeon technique, we successfully standardized and introduced the RDP program. The two-surgeon technique can contribute to the safe introduction of RDP and expansion of the program. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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= en-keyword=Distal pancreatectomy kn-keyword=Distal pancreatectomy en-keyword=Robotic surgery: minimally invasive surgery kn-keyword=Robotic surgery: minimally invasive surgery en-keyword=Training kn-keyword=Training en-keyword=Outcomes kn-keyword=Outcomes END start-ver=1.4 cd-journal=joma no-vol=39 cd-vols= no-issue=5 article-no= start-page=3137 end-page=3145 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of visceral fat area on surgical difficulty during robotic distal pancreatectomy (TAKUMI-2) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Difficulty scoring systems (DSS) have been developed to quantify the surgical complexity of laparoscopic distal pancreatectomy (LDP). However, few studies have validated these systems in the context of robotic distal pancreatectomy (RDP). Moreover, the impact of body composition on RDP outcomes remains unexplored. This study aimed to investigate the risk factors of surgical difficulty in RDP, including body composition.
Methods: This retrospective study included 72 consecutive patients who underwent RDP at our institution between April 2021 and October 2024. Using a modified DSS for LDP, patients were divided into three difficulty index groups. The association between the difficulty index and outcomes was investigated. Multivariate analyses were performed to identify risk factors associated with surgical difficulty (prolonged operative time) in RDP.
Results: Patients were classified into three difficulty index groups: low (n?=?28), intermediate (n?=?25), and high (n?=?19). Operative time was significantly associated with the surgical index (P?=?0.01). Moreover, visceral fat area (VFA) was significantly correlated with operative time (r2?=?0.10, P?=?0.008). The multivariate analyses found that VFA (??100 cm2) (odds ratio [OR] 5.03, 95% confidence interval [CI] 1.32?22.4, P?=?0.02), malignancy (OR 4.92, 95% CI 1.50?18.9, P?=?0.01), and pancreatic resection on the portal vein (OR 4.14, 95% CI 1.24?15.9, P?=?0.02) were significant risk factors associated with surgical difficulty.
Conclusion: VFA could be a novel and useful factor for assessing the surgical difficulty associated with RDP. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamadaMotohiko en-aut-sei=Yamada en-aut-mei=Motohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishiyamaTakeyoshi en-aut-sei=Nishiyama en-aut-mei=Takeyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NagaiYasuo en-aut-sei=Nagai en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KanehiraNoriyuki en-aut-sei=Kanehira en-aut-mei=Noriyuki 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 Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Robotic distal pancreatectomy kn-keyword=Robotic distal pancreatectomy en-keyword=Difficulty score kn-keyword=Difficulty score en-keyword=Visceral fat area kn-keyword=Visceral fat area END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=e70069 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Metachronous Pancreatic Metastasis of Myxoid Liposarcoma Successfully Treated With Robotic Spleen‐Preserving Distal Pancreatectomy With Splenic Vessels Resections: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pancreatic metastasis of myxoid liposarcoma (MLS) after primary resection is extremely rare. Herein, we present a case of metachronous pancreatic metastasis of MLS that was successfully treated with robotic spleen-preserving distal pancreatectomy (SPDP) using the Warshaw technique. A 60-year-old woman underwent radical resection of a 25-cm MLS in the right thigh after receiving neoadjuvant radiotherapy. The patient developed a 6-cm solitary pancreatic metastasis of the MLS 2?years later. Because no other distant metastases were detected, robotic SPDP (Warshaw technique) was performed. The operative time was 140?min with minimal blood loss. Follow-up at 3?months showed no recurrence. To our knowledge, this is the first report of a case of metachronous pancreatic metastasis of MLS successfully treated with robotic SPDP. Curative resection using minimally invasive surgery should be performed for solitary pancreatic metastases from MLS. en-copyright= kn-copyright= en-aut-name=SotaYumi en-aut-sei=Sota en-aut-mei=Yumi 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=YamadaMotohiko en-aut-sei=Yamada en-aut-mei=Motohiko 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=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishiyamaTakeyoshi en-aut-sei=Nishiyama en-aut-mei=Takeyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NagaiYasuo en-aut-sei=Nagai en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KanehiraNoriyuki en-aut-sei=Kanehira en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MasunagaAkari en-aut-sei=Masunaga en-aut-mei=Akari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=myxoid liposarcoma kn-keyword=myxoid liposarcoma en-keyword=pancreatic metastasis kn-keyword=pancreatic metastasis en-keyword=robotic surgery kn-keyword=robotic surgery END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue= article-no= start-page=103078 end-page= 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=Rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone combined with high-dose methotrexate plus intrathecal chemotherapy for newly diagnosed intravascular large B-cell lymphoma (PRIMEUR-IVL): long-term results of a multicentre, single-arm, phase 2 trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Intravascular large B-cell lymphoma (IVLBCL) is a rare type of extranodal large B-cell lymphoma for which prognosis is typically poor without a timely diagnosis. To explore the safety and efficacy of standard chemotherapy combined with central nervous system (CNS)-directed therapy, we conducted a multicentre, single-arm, phase 2 trial in untreated IVLBCL patients without CNS involvement at diagnosis (PRIMEUR-IVL). In the primary analysis, the PRIMEUR-IVL study demonstrated 2-year progression-free survival (PFS) of 76% and 2-year overall survival (OS) of 92% with a low incidence (3%) of secondary CNS involvement (sCNSi).
Methods We present a prespecified final analysis of the PRIMEUR-IVL study including 5-year PFS, OS and cumulative incidence of sCNSi. Participants were enrolled between June 2011 and July 2016, and the data cutoff date for the final analysis was 16 November 2021. The trial was registered in the UMIN Clinical Trial Registry (UMIN000005707) and the Japan Registry of Clinical Trials (jRCTs041180165).
Findings With a median follow-up of 7.1 years (interquartile range 5.6?8.7), 5-year PFS in all 37 eligible patients was 68% (95% confidence interval [CI] 50%?80%) and OS was 78% (95% CI 61%?89%). No additional sCNSi was observed after the primary analysis. Severe adverse events after the primary analysis were grade 4 neutropenia (n = 1) and grade 4 myelodysplastic syndrome that did not require specific treatment (n = 1). Eight deaths occurred during the observation period after enrolment, due to primary disease (n = 6), sepsis (n = 1) and unknown sudden death (n = 1).
Interpretation Long-term follow-up data demonstrated durable response for PFS and OS, and low cumulative incidence of sCNSi, indicating the efficacy of standard chemotherapy combined with CNS-directed therapy for untreated IVLBCL patients.

Malignant Pleural Mesothelioma Involving the Esophagus en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a rare case of pseudoachalasia secondary to malignant pleural mesothelioma involving the esophagus. A 66-year-old man presented with progressive dysphagia, weight loss, and postprandial hiccups. Endoscopic examination showed esophageal dilation with luminal narrowing at the esophagogastric junction, but no mucosal abnormalities. Computed tomography revealed an irregular-shaped mass extending from the peri-esophagogastric junction to the retroperitoneum, accompanied by pleural effusion, right-sided hydronephrosis, and multiple hepatic lesions. Endoscopic ultrasound-guided fine-needle aspiration from the mass lesion through the esophageal lumen revealed epithelioid malignant mesothelioma. This case highlights the importance of considering malignant mesothelioma in the differential diagnosis of pseudoachalasia, particularly when imaging reveals extrinsic esophageal compression without mucosal lesions. en-copyright= kn-copyright= en-aut-name=HondaManami en-aut-sei=Honda en-aut-mei=Manami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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 Pathology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=endoscopic ultrasound-guided fine-needle aspiration kn-keyword=endoscopic ultrasound-guided fine-needle aspiration en-keyword=esophageal diseases kn-keyword=esophageal diseases en-keyword=esophagogastroduodenoscopy (egd) kn-keyword=esophagogastroduodenoscopy (egd) en-keyword=malignant mesothelioma kn-keyword=malignant mesothelioma en-keyword=pseudoachalasia kn-keyword=pseudoachalasia END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=174 end-page=194 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Redesigning Writing Instruction through Peer?AI?Instructor Collaborative Triadic Feedback：Integrating AI in an Academic Writing Course kn-title=ピア・AI・教員の三者協働フィードバックによるライティング授業の再設計 ―AI利用の実践報告− en-subtitle= kn-subtitle= en-abstract=This paper presents the design of a triadic feedback model for an academic writing course that clarifies the role allocation and sequencing of feedback among peers, AI, and the instructor (student’s own draft → peer feedback → AI feedback（→ metacognitive reflection )→teacher feedback), and it describes its implementation and evaluation in 2024?2025. Post-course student surveys valued AI’s immediacy and capacity for elaboration, while also expressing concerns about dependence and limits to its effectiveness. Grade distributions showed a contraction of the lower-performing band after the introduction of the model, suggesting an overall uplift in learning outcomes. To counter misuse AI, explicit in-class instruction on constructive use, such as privileging diagnostic feedback over canned text and requiring metacognitive justification for accepting or rejecting AI suggestions, proved effective. We thus present the effectiveness and remaining challenges of a course design that leverages AI’s potential while keeping human judgment and ethics at its core. kn-abstract=本稿は、アカデミック・ライティング授業におけるピア・AI・教員のそれぞれの役割と利用順序（自分→ピア→AI→（省察）→教員）を組み込んだ三者協働モデルを設計し、2024〜2025年度に実践した内容を報告する。授業後の学生アンケートでは、AIの即時性・精緻化が評価される一方、依存や有効性の限界に関する懸念も表明された。成績分布においては、AI導入後に下位層が縮小し、学習成果の底上げが示唆された。また、AI誤用や濫用を防ぐには、教室内で建設的な利用法の具体的な指導（例：例文より診断的フィードバックを重視、AI提案の採否理由のメタ記述）が効果的であった。これらの結果から、AIの利点を活かしつつ、学生の判断を中心に据えるライティング授業設計の有効性と課題を提示する。 en-copyright= kn-copyright= en-aut-name=UzukaMariko en-aut-sei=Uzuka en-aut-mei=Mariko kn-aut-name=宇塚万里子 kn-aut-sei=宇塚 kn-aut-mei=万里子 aut-affil-num=1 ORCID= affil-num=1 en-affil=Institute for Promotion of Education and Campus Life kn-affil=教育推進機構 en-keyword=生成 AI kn-keyword=生成 AI en-keyword=アカデミック・ライティング kn-keyword=アカデミック・ライティング en-keyword=ピア評価 kn-keyword=ピア評価 en-keyword=メタ認知 kn-keyword=メタ認知 en-keyword=AI リテラシー kn-keyword=AI リテラシー END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=155 end-page=173 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=An Attempt at Extensive Reading in Chinese at the Pre-Intermediate Level kn-title=大学における中国語多読の試み en-subtitle= kn-subtitle= en-abstract= kn-abstract=　This study examines the implementation of the instruction for extensive reading in Chinese among 19 learners who completed one year of beginner-level Chinese studies comprising two 100-minute sessions per week.

The method employs a power-variable artificial microwave source under feedback control from the detector under test on the telescope. It enables us to extend the dynamic range of the beam pattern measurement without introducing nonlinearity effects from the detector. We conducted a laboratory-based proof-of-concept experiment, measuring the H-plane beam pattern of a horn antenna coupled to a diode detector at 81 GHz. We gained an additional dynamic range of 60.3 dB attributed to the feedback control. In addition, we verified the measurement by comparing it with other reference measurements obtained using conventional methods. The method is also applicable to general optical measurements requiring a high dynamic range to detect subtle nonidealities in the characteristics of optical devices. en-copyright= kn-copyright= en-aut-name=HiroseHaruaki en-aut-sei=Hirose en-aut-mei=Haruaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HasegawaMasaya en-aut-sei=Hasegawa en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanekoDaisuke en-aut-sei=Kaneko en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NagasakiTaketo en-aut-sei=Nagasaki en-aut-mei=Taketo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakakuRyota en-aut-sei=Takaku en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=de?HaanTijmen en-aut-sei=de?Haan en-aut-mei=Tijmen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakakuraSatoru en-aut-sei=Takakura en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujinoTakuro en-aut-sei=Fujino en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Physics, Graduate School of Engineering Science, Yokohama National University kn-affil= affil-num=2 en-affil=Institute of Particle and Nuclear Studies (IPNS), High Energy Accelerator Research Organization (KEK) kn-affil= affil-num=3 en-affil=International Center for Quantum-field Measurement Systems for Studies of the Universe and Particles (WPI-QUP), High Energy Accelerator Research Organization (KEK) kn-affil= affil-num=4 en-affil=Accelerator Laboratory (ACCL), High Energy Accelerator Research Organization (KEK) kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Institute of Particle and Nuclear Studies (IPNS), High Energy Accelerator Research Organization (KEK) kn-affil= affil-num=7 en-affil=Department of Physics, Faculty of Science, The University of Tokyo kn-affil= affil-num=8 en-affil=International Center for Quantum-field Measurement Systems for Studies of the Universe and Particles (WPI-QUP), High Energy Accelerator Research Organization (KEK) kn-affil= END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=2 article-no= start-page=e1375 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association Between Positive End-Expiratory Pressure at Venovenous Extracorporeal Membrane Oxygenation Initiation and Liberation Outcomes in Acute Respiratory Distress Syndrome: A Multicenter Retrospective Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=IMPORTANCE: The optimal level of positive end-expiratory pressure (PEEP) during venovenous extracorporeal membrane oxygenation (ECMO) for acute respiratory distress syndrome (ARDS) remains uncertain.
OBJECTIVES: This study aimed to evaluate the association between initial PEEP settings at ECMO initiation and the rate of successful ECMO liberation in patients with severe ARDS.
DESIGN, SETTING, AND PARTICIPANTS: We conducted a post hoc analysis of the multicenter Japan Chest CT for ARDS Requiring Venovenous ECMO (J-CARVE) registry. Adult patients with severe ARDS treated with venovenous ECMO between 2012 and 2022 at 24 institutions were included. Participants were categorized into three groups according to PEEP at ECMO initiation: low (< 8?cm H2O), middle (8?10?cm H2O), and high (> 10?cm H2O).
MAIN OUTCOMES AND MEASURES: The primary outcome was successful liberation from ECMO within 30 days. Multivariable Cox proportional hazards models were used to evaluate associations. Secondary outcomes included 60-day mortality, duration of ECMO support, and duration of mechanical ventilation.
RESULTS: Among 683 patients analyzed, the overall ECMO liberation rate at 30 days was 69.2%. Liberation rates were 57.8% (103/178), 73.5% (259/352), and 72.5% (111/153) in the low, middle, and high PEEP groups, respectively. After adjustment, the low group had a significantly lower likelihood of successful ECMO liberation (hazard ratio [HR], 0.56; 95% CI, 0.39?0.81) compared with the middle group. No significant difference was observed between the high and middle groups (HR, 0.80; 95% CI, 0.58?1.10). The low group had longer ECMO duration; however, 60-day mortality and hospital length of stay did not differ significantly among groups.
CONCLUSIONS AND RELEVANCE: Lower PEEP levels at ECMO initiation were associated with reduced likelihood of successful ECMO liberation compared with moderate PEEP, whereas estimates for high vs. moderate PEEP were not statistically significant. These findings support avoiding insufficiently low PEEP and underscore the need for prospective studies to refine optimal PEEP strategies in patients with severe ARDS. en-copyright= kn-copyright= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KosakiYoshinori en-aut-sei=Kosaki en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=NishikimiMitsuaki en-aut-sei=Nishikimi en-aut-mei=Mitsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OhshimoShinichiro en-aut-sei=Ohshimo en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShimeNobuaki en-aut-sei=Shime en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= 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= 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 and Critical Care Medicine, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=5 en-affil=Department of Emergency and Critical Care Medicine, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=6 en-affil=Department of Emergency and Critical Care Medicine, Graduate School of Biomedical and Health Sciences, Hiroshima 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= en-keyword=acute respiratory distress syndrome kn-keyword=acute respiratory distress syndrome en-keyword=extracorporeal membrane oxygenation kn-keyword=extracorporeal membrane oxygenation en-keyword=mechanical ventilation kn-keyword=mechanical ventilation en-keyword=respiratory therapy kn-keyword=respiratory therapy en-keyword=weaning kn-keyword=weaning END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=11 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260105 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association of Wet-Bulb Globe Temperature with heat-related illness hospitalizations in Japan: a time-stratified, case-crossover study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Heat-related illnesses are a serious public health concern and are exacerbated by global warming. Wet-Bulb Globe Temperature (WBGT) is widely used as a heat stress indicator, but its clinical impact remains unclear. This study aimed to investigate the association between hourly variations in WBGT and the incidence of hospitalizations for heat-related illness in Japan using a nationwide database. By incorporating individual-level clinical data and performing stratified analyses, we sought to provide a more granular understanding of how heat exposure affects the risk of heat-related illness requiring hospitalization.
Methods We conducted a time-stratified, case-crossover study using data collected from July to September in 2020 and 2021 in the Heatstroke STUDY registry. The inclusion criteria were patients registered in the Heatstroke STUDY registry, specifically hospitalized patients with heat-related illness who were transported to participating hospitals during the study period. Hourly WBGT values were assigned based on the nearest monitoring station to each hospital. Conditional logistic regression and distributed lag models were used to estimate associations between WBGT and the risk of hospitalization.
Results A total of 1,653 heat-related illness hospitalizations were analyzed. The mean patient age was 67.9 years; 67.6% were male. Each 1 °C increase in WBGT at onset (hospital arrival) was associated with a significantly increased risk of hospitalization (OR 1.10, 95% CI: 1.05?1.15). The cumulative effect over the prior six hours was also significant (OR 1.56, 95% CI: 1.50?1.62). Compared with WBGT? Conclusions Higher WBGT levels were associated with an increased risk of heat-related hospitalization. Although the effect appeared greater in some subgroups, only patients with mental disorders demonstrated statistically significant effect modification, suggesting elevated WBGT confers risk broadly. en-copyright= kn-copyright= en-aut-name=YamamuraYuka en-aut-sei=Yamamura en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SasaiFumiya en-aut-sei=Sasai en-aut-mei=Fumiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TokiokaKohei en-aut-sei=Tokioka en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=KandaJun en-aut-sei=Kanda en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YokoboriShoji en-aut-sei=Yokobori en-aut-mei=Shoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Epidemiology, Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Emergency and Critical Care Medicine, Nippon Medical School Musashikosugi Hospital kn-affil= affil-num=9 en-affil=Department of Emergency and Critical Care Medicine, Nippon Medical School kn-affil= affil-num=10 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Epidemiology, Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Wet-Bulb Globe Temperature kn-keyword=Wet-Bulb Globe Temperature en-keyword=Heat stroke kn-keyword=Heat stroke en-keyword=Heat related illness kn-keyword=Heat related illness en-keyword=Global warming kn-keyword=Global warming END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=2 article-no= start-page=e7467 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Technique for Repositioning the Posteriorly Displaced Premaxilla Following Prior Repair of Complete Bilateral Cleft Lip en-subtitle= kn-subtitle= en-abstract= kn-abstract=It is well known that osteotomy of the premaxilla is an effective surgical procedure for the correction of a displaced premaxilla in patients with bilateral cleft lip and palate. In cases with a posteriorly displaced premaxilla, it is not easy to move the premaxilla forward because of scarring of the palatal mucosal attachment, narrowing of the adjacent maxillary segments, and the stable fixation of this bone segment after its movement. This fixation is also important in cases without secondary bone grafting. We propose a new method that combines osteotomy and a method such as bone distraction for cases with significant premaxilla displacement that are difficult to repair by osteotomy alone. A conventional orthodontic palatal expander was used as the distractor. The anterior arms were bent at the posterior part of the lingual side of the anterior teeth, and a resin base was attached to the arm parts. The posterior arms were bent and waxed onto the bands of both first molars. Supportive stainless steel wire arms, which are attached to the rest of the deciduous molars, stabilize the distractor. After the osteotomy of the premaxilla, distraction was performed at a rate of 1.0 mm per day, starting the day after surgery. Because the premaxilla of patients with bilateral cleft lip and palate has undergone multiple surgical interventions, the soft tissue is not mobile, making it impossible to guide the premaxilla to an ideal position in a single stage. However, this procedure, using this semirigid distractor, makes it possible to move the osteotomized premaxilla to the planned position with firm stability. en-copyright= kn-copyright= en-aut-name=ArimuraYuki en-aut-sei=Arimura en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IidaSeiji en-aut-sei=Iida en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HyodoAiko en-aut-sei=Hyodo en-aut-mei=Aiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MikamiAyaka en-aut-sei=Mikami en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HayanoSatoru en-aut-sei=Hayano en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakemotoFumiko en-aut-sei=Takemoto en-aut-mei=Fumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Department of Oral and Maxillofacial Reconstructive Surgery, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Reconstructive Surgery, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Advanced Cleft Lip and Cleft Palate Center, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Reconstructive Surgery, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Advanced Cleft Lip and Cleft Palate Center, Okayama University Hospital kn-affil= affil-num=6 en-affil=Advanced Cleft Lip and Cleft Palate Center, Okayama University Hospital kn-affil= affil-num=7 en-affil=Advanced Cleft Lip and Cleft Palate Center, Okayama University Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=1 article-no= start-page=96 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260109 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of an oral exercise intervention on pre-frailty or frailty in older people: a randomized clinical trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Frailty is often experienced by older adults, which can lead to long-term health problems. We aimed to examine associations with improvements in nutritional status, sarcopenia (age-related loss of skeletal muscle mass and strength), and frailty in four groups with different oral exercise frequencies.
Methods: We conducted a prospective, parallel multi-arm randomized controlled trial (Japan Registry of Clinical Trials (jRCT) 1062210063) to test the effects of oral exercise on frailty in older adults. Each intervention consisted of a standardized oral exercise protocol including neck exercises, lip exercises, and tongue movements, designed to improve oral function and reduce frailty. The primary outcome was the change in the number of frailty criteria from baseline to follow-up. Individuals aged ?60 years were screened for frailty status using standardized criteria at the Department of Preventive Dentistry at Okayama University Hospital between October 2022 and December 2023. Those identified as pre-frailty or frailty were eligible and enrolled in the study. After screening 60 individuals, 58 eligible participants were randomly assigned using block randomization to one of four oral exercise frequency groups: 3 times/day & everyday, 3 times/day & 3 days/week, once/day & everyday, and once/day & 3 days/week. A two-way repeated measures analysis of variance was used to evaluate the impact of the four frequencies of oral exercise methods on frailty in older adults. Outcome assessors were blinded; participants were not.
Results: Here we show the results of the 58 participants. Group sizes are: 3 times/day & everyday (n?=?14), 3 times/day & 3 days/week (n?=?15), once/day & everyday (n?=?14), once/day & 3 days/week (n?=?15). The trial is completed as planned, and all randomized participants are analyzed. The main effect of time is significant for the number of frailty criteria (F?=?14.803, p? Conclusions: After conducting oral exercises for 3 months on older adults with pre-frailty or frailty, improvements in frailty are observed. Overall, these exercises could be a simple, low-cost way to support healthy aging in the community. 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=InadaSakura en-aut-sei=Inada en-aut-mei=Sakura 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= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Division of Dentistry, Medical Development Field, Okayama University kn-affil= affil-num=2 en-affil=Section of Preventive and Public Health Dentistry, Division of Oral Health, Growth and Development, Faculty of Dental Science, Kyushu University kn-affil= affil-num=3 en-affil=Division of Health Promotion, Okayama-City Health Center kn-affil= affil-num=4 en-affil=Department of Oral Health Sciences, Faculty of Health Care Sciences, Takarazuka University of Medical and Health Care kn-affil= affil-num=5 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue= article-no= start-page=e5 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of sagging correction calibration error on radiation therapy equipment using image analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: This study investigates the effect of sagging correction errors on image quality and geometric coordinate accuracy.
Methods: This study utilised the Elekta radiotherapy system, ball bearing (BB), Catphan phantom and MultiMet-WL phantom. Ten distinct flex maps (FMs) were acquired by positioning the BB at the accuracy isocentre and introducing shifts of 0.2, 0.4 and 0.6 mm in the left, table and up directions, respectively. Cone-beam computed tomography images of the Catphan phantom were acquired using 10 FMs. The images were analysed for modulation transfer function (MTF) values and geometric coordinates. Additionally, the Winston?Lutz (W-L) test was conducted under reference couch positions and with a 0.3 mm couch shift.
Results: For the Catphan phantom analysis, the standard deviations of MTF10% across FMs were 0.19. The centre-of-gravity coordinates of the insert exhibited shifts of approximately 0.2, 0.4 and 0.6 mm when comparing reference images to those acquired with the shifted FMs. The results of the W-L test with a 0.3 mm couch shift showed radiation isocentre deviations exceeding 1 mm compared to the reference couch positions.
Conclusions: Minor sagging correction calibration errors did not remarkably impact image quality; however, they altered the geometric coordinates of the image isocentre. These calibration errors decreased the accuracy of off-isocentre positioning. en-copyright= kn-copyright= en-aut-name=FujiiYasushi en-aut-sei=Fujii en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakayamaTakahiro en-aut-sei=Nakayama en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OshitaJunki en-aut-sei=Oshita en-aut-mei=Junki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsunodaAyaka en-aut-sei=Tsunoda en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SaekiYusuke en-aut-sei=Saeki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanabeYoshinori en-aut-sei=Tanabe en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Radiology, Chugoku Central Hospital of the Mutual Aid Association of Public School Teachers kn-affil= affil-num=2 en-affil=Department of Radiology, Chugoku Central Hospital of the Mutual Aid Association of Public School Teachers kn-affil= affil-num=3 en-affil=Department of Radiology, Chugoku Central Hospital of the Mutual Aid Association of Public School Teachers kn-affil= affil-num=4 en-affil=Department of Radiology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Kawasaki Medical School Hospital kn-affil= affil-num=6 en-affil= Faculty of Medicine, Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=flex map kn-keyword=flex map en-keyword=sagging kn-keyword=sagging en-keyword=Winston?Lutz test kn-keyword=Winston?Lutz test END start-ver=1.4 cd-journal=joma no-vol=164 cd-vols= no-issue= article-no= start-page=108315 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Global trends in Clostridioides difficile infection?related mortality, 2001-2023: An observational study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Clostridioides difficile infection (CDI) is a major public health concern, particularly in aging populations. The aim of this study was to evaluate global trends in CDI-related mortality to inform sustainable and cost-effective management strategies.
Methods: We conducted an observational study using mortality data from the World Health Organization (WHO) database spanning 2001 to 2023. Sixty-three countries with satisfactory data quality and at least 12 years of data between 2001 and 2023 were included. Crude and age-standardized CDI-related mortality rates per 1,000,000 individuals were calculated after stratification by age, sex, WHO region, and sociodemographic index (SDI). Global trends were analyzed using locally weighted regression.
Results: The global age-standardized CDI-related mortality rate was 0.76 per 1,000,000 individuals in 2001, peaked at 4.08 in 2010, and declined to 2.44 in 2023. The most notable downward trends were observed in the Americas and high-SDI countries. These improvements may reflect the impact of multidisciplinary efforts in CDI prevention and management.
Conclusions: Although CDI-related mortality has declined globally over the past decade, the disease remains a significant threat, especially in older populations. Ongoing global efforts are essential to further reduce CDI-related deaths. 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=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaradaKo en-aut-sei=Harada en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoMaki en-aut-sei=Yamamoto en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakedaTatsuaki en-aut-sei=Takeda en-aut-mei=Tatsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=VuQuynh Thi en-aut-sei=Vu en-aut-mei=Quynh Thi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=BelangoyKeith Pardillada en-aut-sei=Belangoy en-aut-mei=Keith Pardillada kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OuddoudHanane en-aut-sei=Ouddoud en-aut-mei=Hanane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KoyamaToshihiro en-aut-sei=Koyama en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=2 en-affil=Division of Hematology/Oncology, Mayo Clinic kn-affil= affil-num=3 en-affil=Brookdale Department of Geriatrics and Palliative Medicine, Icahn School of Medicine at Mount Sinai kn-affil= affil-num=4 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil= kn-affil= affil-num=6 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Aging kn-keyword=Aging en-keyword=Locally weighted regression model kn-keyword=Locally weighted regression model en-keyword=Infection kn-keyword=Infection en-keyword=Clostridioides difficile kn-keyword=Clostridioides difficile en-keyword=Disparity kn-keyword=Disparity END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=3 article-no= start-page=102931 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tick-borne pathogens in ticks collected from Humans: A prospective clinical pilot study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tick-borne diseases (TBDs), particularly Japanese spotted fever, are an increasing public health concern in Japan. Data on pathogens carried by ticks removed directly from patients and their associated clinical outcomes remain limited. This prospective study investigated pathogen carriage in patient-derived ticks and evaluated the clinical risk of TBDs. Between April and October 2025, ticks were collected from patients presenting with tick bites at two medical institutions in Western Japan. Ticks were morphologically identified and spotted fever group rickettsiae (SFGR) was detected by nested PCR targeting the 17-kDa antigen gene, followed by sequence analysis. Clinical data, including patient background, antibiotic prescriptions, and outcomes, were reviewed. Clinical information was available for 70 patients (median age; 75 years), of whom 88.6% were prescribed prophylactic antibiotics. Ticks were collected from 60 patients (85.7%), and seven adults without antibiotic prophylaxis were followed for disease onset. Sixty-two ticks, predominantly Amblyomma testudinarium (88.7%), were analyzed. SFGR was detected in eight ticks (12.9%), including seven A. testudinarium and one Ixodes nipponensis, collected from seven patients. Two patients bitten by Rickettsia tamurae?carrying ticks were observed for one month without antibiotics and remained asymptomatic. In this prospective analysis, no clinically apparent rickettsiosis was observed following bites from R. tamurae?positive ticks without antibiotic prophylaxis; however, subclinical infection could not be excluded. Despite the small sample size, our findings suggest that the clinical risk associated with R. tamurae infection may be low. Direct analysis of removed ticks from patients may help characterize pathogen reservoirs and inform targeted approaches to TBDs. en-copyright= kn-copyright= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SumidaTakaomi en-aut-sei=Sumida en-aut-mei=Takaomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawamataOsamu en-aut-sei=Kawamata en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HidaniYoshimi en-aut-sei=Hidani en-aut-mei=Yoshimi 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=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Numakuma Hospital kn-affil= affil-num=3 en-affil=Numakuma Hospital kn-affil= affil-num=4 en-affil=Numakuma Hospital kn-affil= affil-num=5 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= en-keyword=Epidemiology kn-keyword=Epidemiology en-keyword=Japanese spotted fever kn-keyword=Japanese spotted fever en-keyword=Spotted fever group rickettsiae kn-keyword=Spotted fever group rickettsiae en-keyword=Tick bite kn-keyword=Tick bite en-keyword=Tick-borne disease kn-keyword=Tick-borne disease END start-ver=1.4 cd-journal=joma no-vol=112 cd-vols= no-issue=2 article-no= start-page=2301 end-page=2310 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251010 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Total thymectomy is oncologically superior to partial thymectomy in patients with thymic carcinoma: insights from a multicenter real-world data analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Although total thymectomy has been the standard surgical approach for thymic epithelial tumors, an increasing number of recent reports suggest that partial thymectomy for early-stage thymomas may yield outcomes comparable to those of total thymectomy. However, whether partial thymectomy is a viable alternative for thymic carcinoma remains unclear.
Materials and methods: A total of 106 patients with thymic carcinoma underwent curative intended resection at 19 institutions between January 2010 and December 2021. Excluding 14 patients with incomplete resection, 92 patients with thymic carcinoma who underwent total (n = 73) or partial thymectomy (n = 19) were compared. Overall survival (OS) and recurrence-free survival (RFS) were analyzed using Kaplan?Meier curves and Cox proportional hazard models. Overlap weighting was applied to adjust for potential confounding factors.
Results: Among patients with clinical stage I disease, 79.3% were upstaged to stage II or higher postoperatively. Unadjusted analyses revealed no statistically significant differences in OS and RFS between the total and partial thymectomy groups, although a trend toward poorer outcomes in the partial thymectomy group was observed. After overlap weighting, partial thymectomy was associated with significantly poorer OS (P = 0.0027) and higher recurrence risk (P < 0.0001). Early postoperative recurrence occurred more frequently in the partial thymectomy group.
Conclusion: Partial thymectomy was associated with significantly worse survival and recurrence outcomes in thymic carcinoma. Given the limitations of preoperative diagnosis, total thymectomy should remain the preferred surgical approach for undiagnosed thymic epithelial tumors to achieve optimal oncologic control and minimize the risk of recurrence. en-copyright= kn-copyright= en-aut-name=HayashiTatsuya en-aut-sei=Hayashi en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

for Video Presentation Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=With the rapid growth of online presentations, there has been an increasing need for efficient review of recorded materials. In typical presentations, speakers verbally elaborate on each slide, providing details not captured in the slides themselves. Automatically extracting and embedding these verbal explanations at their corresponding slide locations can greatly enhance the review process for audiences. This paper presents a Slide Annotation System that employs a robust hybrid two-stage detector to identify slide boundaries, extracts slide text through Optical Character Recognition (OCR), transcribes narration, and employs a multimodal Large Language Model (LLM) to generate concise, context-aware annotations that are added to their corresponding slide locations. For evaluations, the technical performance was validated on five recorded presentations, while the user experience was assessed by 37 participants. The results showed that the system achieved a macro-average ?1 score of 0.879 (??=0.024, 95% ??[0.849,0.909]) for slide segmentation and 90.0% accuracy (95% ??[74.4%,96.5%]) for annotation alignment. Subjective evaluations revealed high annotation validity and usefulness as rated by presenters, and a high System Usability Scale (SUS) score of 80.5 (??=6.7, 95% ??[78.3,82.7]). Qualitative feedback further confirmed that the system effectively streamlined the review process, enabling users to locate key information more efficiently than standard video playback. These findings demonstrate the strong potential of the proposed system as an effective automated annotation system. en-copyright= kn-copyright= en-aut-name=HazAmma Liesvarastranta en-aut-sei=Haz en-aut-mei=Amma Liesvarastranta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BrataKomang Candra en-aut-sei=Brata en-aut-mei=Komang Candra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KyawHtoo Htoo Sandi en-aut-sei=Kyaw en-aut-mei=Htoo Htoo Sandi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FajriantiEvianita Dewi en-aut-sei=Fajrianti en-aut-mei=Evianita Dewi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SukaridhotoSritrusta en-aut-sei=Sukaridhoto en-aut-mei=Sritrusta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=5 en-affil=Human Centric Multimedia Research Laboratory, Department of Informatic and Computer Engineering, Politeknik Elektronika Negeri Surabaya kn-affil= affil-num=6 en-affil=Human Centric Multimedia Research Laboratory, Department of Informatic and Computer Engineering, Politeknik Elektronika Negeri Surabaya kn-affil= en-keyword=slide annotation kn-keyword=slide annotation en-keyword=multimodal analysis kn-keyword=multimodal analysis en-keyword=speech-to-text kn-keyword=speech-to-text en-keyword=LLM kn-keyword=LLM en-keyword=SUS kn-keyword=SUS END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=65 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260109 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An SQL Query Description Problem with AI Assistance for an SQL Programming Learning Assistant System en-subtitle= kn-subtitle= en-abstract= kn-abstract=Today, relational databases are widely used in information systems. SQL (structured query language) is taught extensively in universities and professional schools across the globe as a programming language for its data management and accesses. Previously, we have studied a web-based programming learning assistant system (PLAS) to help novice students learn popular programming languages by themselves through solving various types of exercises. For SQL programming, we have implemented the grammar-concept understanding problem (GUP) and the comment insertion problem (CIP) for its initial studies. In this paper, we propose an SQL Query Description Problem (SDP) as a new exercise type for describing the SQL query to a specified request in a MySQL database system. To reduce teachers’ preparation workloads, we integrate a generative AI-assisted SQL query generator to automatically generate a new SDP instance with a given dataset. An SDP instance consists of a table, a set of questions and corresponding queries. Answer correctness is determined by enhanced string matching against an answer module that includes multiple semantically equivalent canonical queries. For evaluation, we generated 11 SDP instances on basic topics using the generator, where we found that Gemini 3.0 Pro exhibited higher pedagogical consistency compared to ChatGPT-5.0, achieving perfect scores in Sensibleness, Topicality, and Readiness metrics. Then, we assigned the generated instances to 32 undergraduate students at the Indonesian Institute of Business and Technology (INSTIKI). The results showed an average correct answer rate of 95.2% and a mean SUS score of 78, which demonstrates strong initial student performance and system acceptance. en-copyright= kn-copyright= en-aut-name=WardaniNi Wayan en-aut-sei=Wardani en-aut-mei=Ni Wayan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KyawHtoo Htoo Sandi en-aut-sei=Kyaw en-aut-mei=Htoo Htoo Sandi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZhuZihao en-aut-sei=Zhu en-aut-mei=Zihao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KotamaI Nyoman Darma en-aut-sei=Kotama en-aut-mei=I Nyoman Darma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SugiartawanPutu en-aut-sei=Sugiartawan en-aut-mei=Putu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=PutraI Nyoman Agus Suarya en-aut-sei=Putra en-aut-mei=I Nyoman Agus Suarya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Business and Creative Design, Indonesian Institute of Business and Technology kn-affil= en-keyword=database programming kn-keyword=database programming en-keyword=SQL query description problem (SDP) kn-keyword=SQL query description problem (SDP) en-keyword=self-study kn-keyword=self-study en-keyword=programming learning assistant system (PLAS) kn-keyword=programming learning assistant system (PLAS) en-keyword=generative AI kn-keyword=generative AI END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=2 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Threshold Selection Method in Code Plagiarism Checking Function for Code Writing Problem in Java Programming Learning Assistant System Considering AI-Generated Codes en-subtitle= kn-subtitle= en-abstract= kn-abstract=To support novice learners, the Java programming learning assistant system (JPLAS) has been developed with various features. Among them, code writing problem (CWP) assigns writing an answer code that passes a given test code. The correctness of an answer code is validated by running it on JUnit. In previous works, we implemented a code plagiarism checking function that calculates the similarity score for each pair of answer codes based on the Levenshtein distance. When the score is higher than a given threshold, this pair is regarded as plagiarism. However, a method for finding the proper threshold has not been studied. In addition, AI-generated codes have become threats in plagiarism, as AI has grown in popularity, which should be investigated. In this paper, we propose a threshold selection method based on Tukey’s IQR fences. It uses a custom upper threshold derived from the statistical distribution of similarity scores for each assignment. To better accommodate skewed similarity distributions, the method introduces a simple percentile-based adjustment for determining the upper threshold. We also design prompts to generate answer codes using generative AI and apply them to four AI models. For evaluation, we used a total of 745 source codes of two datasets. The first dataset consists of 420 answer codes across 12 CWP instances from 35 first-year undergraduate students in the State Polytechnic of Malang, Indonesia (POLINEMA). The second dataset includes 325 answer codes across five CWP assignments from 65 third-year undergraduate students at Okayama University, Japan. The applications of our proposals found the following: (1) any pair of student codes whose score is higher than the selected threshold has some evidence of plagiarism, (2) some student codes have a higher similarity than the threshold with AI-generated codes, indicating the use of generative AI, and (3) multiple AI models can generate code that resembles student-written code, despite adopting different implementations. The validity of our proposal is confirmed. en-copyright= kn-copyright= en-aut-name=PermatasariPerwira Annissa Dyah en-aut-sei=Permatasari en-aut-mei=Perwira Annissa Dyah kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MentariMustika en-aut-sei=Mentari en-aut-mei=Mustika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KinariSafira Adine en-aut-sei=Kinari en-aut-mei=Safira Adine kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AungSoe Thandar en-aut-sei=Aung en-aut-mei=Soe Thandar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KyawHtoo Htoo Sandi en-aut-sei=Kyaw en-aut-mei=Htoo Htoo Sandi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WaiKhaing Hsu en-aut-sei=Wai en-aut-mei=Khaing Hsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Engineering Science, Akita University kn-affil= en-keyword=Java programming learning kn-keyword=Java programming learning en-keyword=JPLAS kn-keyword=JPLAS en-keyword=JUnit kn-keyword=JUnit en-keyword=code writing problem kn-keyword=code writing problem en-keyword=plagiarism kn-keyword=plagiarism en-keyword=Levenshtein distance kn-keyword=Levenshtein distance en-keyword=threshold kn-keyword=threshold en-keyword=IQR kn-keyword=IQR en-keyword=AI-generated kn-keyword=AI-generated END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=24 article-no= start-page=4967 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251218 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An AI-Driven System for Learning MQTT Communication Protocols with Python Programming en-subtitle= kn-subtitle= en-abstract= kn-abstract=With rapid developments of wireless communication and Internet of Things (IoT) technologies, an increasing number of devices and sensors are interconnected, generating massive amounts of data in real time. Among the underlying protocols, Message Queuing Telemetry Transport (MQTT) has become a widely adopted lightweight publish?subscribe standard due to its simplicity, minimal overhead, and scalability. Then, understanding such protocols is essential for students and engineers engaging in IoT application system designs. However, teaching and learning MQTT remains challenging for them. Its asynchronous architecture, hierarchical topic structure, and constituting concepts such as retained messages, Quality of Service (QoS) levels, and wildcard subscriptions are often difficult for beginners. Moreover, traditional learning resources emphasize theory and provide limited hands-on guidance, leading to a steep learning curve. To address these challenges, we propose an AI-assisted, exercise-based learning platform for MQTT. This platform provides interactive exercises with intelligent feedback to bridge the gap between theory and practice. To lower the barrier for learners, all code examples for executing MQTT communication are implemented in Python for readability, and Docker is used to ensure portable deployments of the MQTT broker and AI assistant. For evaluations, we conducted a usability study using two groups. The first group, who has no prior experience, focused on fundamental concepts with AI-guided exercises. The second group, who has relevant background, engaged in advanced projects to apply and reinforce their knowledge. The results show that the proposed platform supports learners at different levels, reduces frustrations, and improves both engagement and efficiency. en-copyright= kn-copyright= en-aut-name=ZhuZihao en-aut-sei=Zhu en-aut-mei=Zihao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Sandi KyawHtoo Htoo en-aut-sei=Sandi Kyaw en-aut-mei=Htoo Htoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KotamaI Nyoman Darma en-aut-sei=Kotama en-aut-mei=I Nyoman Darma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=PradhanaAnak Agung Surya en-aut-sei=Pradhana en-aut-mei=Anak Agung Surya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=RahmadaniAlfiandi Aulia en-aut-sei=Rahmadani en-aut-mei=Alfiandi Aulia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=Noprianto en-aut-sei=Noprianto en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=7 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= en-keyword=IoT kn-keyword=IoT en-keyword=MQTT protocol kn-keyword=MQTT protocol en-keyword=AI-assisted learning kn-keyword=AI-assisted learning en-keyword=exercise-based education kn-keyword=exercise-based education en-keyword=Python programming kn-keyword=Python programming en-keyword=docker kn-keyword=docker en-keyword=learning platform kn-keyword=learning platform END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=63 end-page=67 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Metastatic Intraocular Tumor Likely from Hepatocellular Carcinoma Mimicking Panuveitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 77-year-old man undergoing treatment for hepatocellular carcinoma (HCC) presented with blurred vision in his right eye, persisting for 2 months.

Radiotherapy was administered to the right eye, with no recurrence of intraocular inflammation observed at 10 months post-irradiation. en-copyright= kn-copyright= en-aut-name=TakasuEri en-aut-sei=Takasu en-aut-mei=Eri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShiodeYusuke en-aut-sei=Shiode en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KindoHiroya en-aut-sei=Kindo en-aut-mei=Hiroya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KimuraShuhei en-aut-sei=Kimura en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HosokawaMio en-aut-sei=Hosokawa en-aut-mei=Mio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatobaRyo en-aut-sei=Matoba en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KanzakiYuki en-aut-sei=Kanzaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=AdachiTakuya en-aut-sei=Adachi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=metastatic intraocular tumor kn-keyword=metastatic intraocular tumor en-keyword=hepatocellular carcinoma kn-keyword=hepatocellular carcinoma en-keyword=panuveitis kn-keyword=panuveitis en-keyword=uveitis masquerade syndrome kn-keyword=uveitis masquerade syndrome END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=55 end-page=62 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Changes in Prescribing Patterns of Antiviral Drugs before and after Public Coverage Termination among Hospitalized COVID-19 Patients in Regional Hospitals in Japan: A Retrospective, Multicenter Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=In Japan, antiviral agents for COVID-19 were freely available until September 2023 as part of national policy. This study evaluated changes in these agents’ prescribing patterns and the patient outcomes following the policy shift. We conducted a multicenter retrospective study at four hospitals in Japan’s Okayama and Kagawa prefectures from January 2022 to March 2024. The study period was divided into the public-expenditure phase (January 2022 to September 2023) and the post-expenditure phase (October 2023 to March 2024). We extracted the hospitalized patients’ clinical data from the electronic database. The study’s primary outcome was the antiviral prescription rate; the secondary outcome was in-hospital mortality. Among the 302 hospitalized patients (median age 85 years), 52.0% were classified as having a mild condition. Of the patients with mild conditions, 37.7% were diagnosed in outpatient settings prior to hospitalization. During the public-expenditure phase, 47.4% of the patients received antivirals as outpatients, mainly molnupiravir (80.9%). In the post-expenditure period, 80.0% of the patients were prescribed antivirals, mostly molnupiravir (91.7%). The antiviral prescription rate was significantly higher after the policy change. The overall in-hospital mortality was 15.8%, with no significant difference between the two periods (17.0% vs. 10.5%). Despite the termination of government funding, antiviral prescriptions remained frequent at community hospitals located in highly aging regions of western Japan such as Okayama and Kagawa prefectures. Mortality remains high among the elderly, highlighting the need for continued antiviral therapy and booster vaccinations. en-copyright= kn-copyright= en-aut-name=AkazawaHidemasa en-aut-sei=Akazawa en-aut-mei=Hidemasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoShohei en-aut-sei=Yamamoto en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, kn-affil= en-keyword=coronavirus disease 2019 kn-keyword=coronavirus disease 2019 en-keyword=public expenditure kn-keyword=public expenditure en-keyword=prescribing pattern kn-keyword=prescribing pattern en-keyword=prognosis kn-keyword=prognosis en-keyword=Japan kn-keyword=Japan END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=31 end-page=37 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Preoperative Anterior Pelvic Plane Angle Predicts Cup Anteversion Changes at 1 Year after Total Hip Arthroplasty en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated global alignment changes following total hip arthroplasty (THA) and predictive alignment parameters for increased cup anteversion (CA) by retrospectively analyzing the primary THA data of 75 patients treated at our hospital (49 women, 26 men; age 65.1±5.7 years, BMI 28.3±3.4 kg/m2). Global alignment parameters, i.e., the anterior pelvic plane angle (APPa) and proximal femoral shaft angle (PFSa) and other alignment parameters were measured. CA was evaluated based on the patients’ standing coronal radiographs. ΔCA was defined as the difference in CA from 2 weeks before to 1 year after each THA. We classified the cases as stable (S) (CA < 10°; n=63) and pelvic retroversion (R) (CA ? 10°; n=12) groups. Associations between ΔCA and alignment parameters were evaluated by linear regression and a receiver operating characteristic (ROC) analysis. A significant decrease in the PFSa occurred between the 2-week and 1-year post-THA timepoints (7.8±4.3° vs. 4.2±3.6°, p<0.001), with no notable change in other alignment parameters. At 1-year post-THA, the CA of 12 (16%) patients had increased to 4.5±4.4°. Only the preoperative APPa was positively associated with ΔCA (β=0.165, p=0.020). The ROC analysis revealed that the optimal cut-off value for increased CA in the APPa is 2.1° (area under the curve, 0.700; p=0.020; odds ratio, 4.80). The APPa change predicted increased CA, which emphasizes the importance of the use of preoperative standing radiography for identifying the optimal cup positioning for post-THA changes in CA. en-copyright= kn-copyright= en-aut-name=IshibashiKyota en-aut-sei=Ishibashi en-aut-mei=Kyota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OishiHirotaka en-aut-sei=Oishi en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ArakiRyo en-aut-sei=Araki en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawamuraKosuke en-aut-sei=Kawamura en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SasakiIsamu en-aut-sei=Sasaki en-aut-mei=Isamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SasakiEiji en-aut-sei=Sasaki en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KamadaHikaru en-aut-sei=Kamada en-aut-mei=Hikaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KogawaMasakazu en-aut-sei=Kogawa en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaSunao en-aut-sei=Tanaka en-aut-mei=Sunao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NumasawaTakuya en-aut-sei=Numasawa en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IshibashiYasuyuki en-aut-sei=Ishibashi en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Hirosaki University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=10 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=11 en-affil=Department of Orthopedic Surgery, Hirosaki University Graduate School of Medicine kn-affil= en-keyword=total hip arthroplasty kn-keyword=total hip arthroplasty en-keyword=global alignment kn-keyword=global alignment en-keyword=anterior pelvic plane kn-keyword=anterior pelvic plane en-keyword=cup anteversion kn-keyword=cup anteversion en-keyword=pelvic tilt kn-keyword=pelvic tilt END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=17 end-page=30 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of a Stroke Discharge Support Evaluation Scale for Ward Nurses in Acute Care Hospitals en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to develop a scale enabling nurses to objectively evaluate their own stroke discharge support, as a basis for enhancing its overall effectiveness. A draft scale was created based on a literature review, and consisted of a 51-item, 5-point Likert-type questionnaire administered to ward nurses engaged in stroke discharge support at acute care hospitals. Factor analysis was performed to refine the scale. Construct validity was assessed using the known-groups method, and reliability was evaluated through internal consistency analysis. The resulting Stroke Discharge Support Evaluation Scale comprises 29 items across 5 factors, each rated on a 5-point Likert scale. Analysis of the data collected from 237 valid responses demonstrated good internal consistency and supported the scale’s construct validity. The Stroke Discharge Support Evaluation Scale is a reliable and valid tool enabling ward nurses in acute care hospitals to evaluate their own stroke discharge support. en-copyright= kn-copyright= en-aut-name=YanoHideki en-aut-sei=Yano en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakahataYoko en-aut-sei=Takahata en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamaguchiTakeshi en-aut-sei=Yamaguchi en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoShinya en-aut-sei=Saito en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Nursing, Faculty of Human Health Sciences, Niimi University kn-affil= affil-num=2 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Nursing, Shikoku University kn-affil= affil-num=4 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=stroke kn-keyword=stroke en-keyword=discharge support kn-keyword=discharge support en-keyword=scale development kn-keyword=scale development END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=1 end-page=7 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Usefulness of D-dimer Assay to Confirm the Course of Overt Venous Thromboembolism (VTE) in Cancer Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Venous thromboembolism (VTE) is a serious complication in patients with cancer. In this population, the presence of thrombi is often assessed at cancer diagnosis by measuring D-dimer levels, which have high sensitivity but low specificity for identifying VTE at this clinical time point. However, the usefulness of D-dimer measurement during anticoagulation therapy has not been fully established, despite its widespread use. In this retrospective observational study, we investigated whether D-dimer measurement during anticoagulation therapy in cancer patients could predict overt VTE at follow-up. The study included patients who underwent D-dimer testing and contrast-enhanced computed tomography between 30 and 100 days after initiation of anticoagulation therapy. Eighty-two patients were included: 60 with cancer and 22 without. The diagnostic performance of D-dimer for overt VTE was as follows: sensitivity, 85.7%; specificity, 87.2%; positive predictive value, 78.3%; and negative predictive value, 89.2%. These findings suggest that D-dimer measurement at follow-up has high sensitivity and specificity for overt VTE in cancer patients and may aid in assessing thrombotic status. Clinically, if anticoagulation therapy is continued until D-dimer levels become negative, the absence of overt VTE could be inferred without additional invasive testing. en-copyright= kn-copyright= en-aut-name=YamaokaHidenaru en-aut-sei=Yamaoka en-aut-mei=Hidenaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshidaMasashi en-aut-sei=Yoshida en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SarashinaToshihiro en-aut-sei=Sarashina en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AkagiSatoshi en-aut-sei=Akagi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=MunemasaMitsuru en-aut-sei=Munemasa en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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= en-aut-name=YuasaShinsuke en-aut-sei=Yuasa en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, IMS Tokyo Katsushika General Hospital 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=Seisukai Kuroda Clinic kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Internal Medicine 3, Kawasaki Medical School General Medical Center kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=D-dimer kn-keyword=D-dimer en-keyword=venous kn-keyword=venous en-keyword=thromboembolism kn-keyword=thromboembolism en-keyword=cancer kn-keyword=cancer END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=134 end-page=152 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Depicting Buddha : Practice, Prescription and Perception en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tibetan thangka refers to a genre of pictorial art widely produced across the Tibetan cultural region since the 11th century. Although scroll painting is its most common form, thangkas are also created through embroidery, appliqu?, and brocade weaving. The subjects depicted encompass a wide range of themes within Tibetan Buddhism and the B?n religion, including various Buddhas, bodhisattvas, deities, monks, mandalas, as well as astronomical and medical knowledge. Within Tibetan religious beliefs, thangkas are not merely visual representations; they are venerated as supports of Buddha (Tib. sku rten), understood as physical embodiments of divine presence. At the same time, the creation and veneration of thangka constitute a rich aesthetic tradition in which artists repeatedly integrate realist elements into this sacred canvas.
This paper offers a micro anthropological examination (Tanaka 2005; 田中 2006) of the depiction of thangka as a practice oscillating between inscribing the canonical and drawing the real. Through critically engaging with the theory of agency of art (Gell 1998), and the analysis of writing and drawing (Ingold 2017), this study examines the dialectical relationship between rendering sacred images and depicting worldly reality, and how such practices unfold in the tension between prescriptive authority and embodied perception. en-copyright= kn-copyright= en-aut-name=ZHANGShijun en-aut-sei=ZHANG en-aut-mei=Shijun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Sociology & Institute of Sociology and Anthropology, Peking University kn-affil= en-keyword=Tibetan thangka kn-keyword=Tibetan thangka en-keyword=art agent kn-keyword=art agent en-keyword=writing and drawing kn-keyword=writing and drawing END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=101 end-page=114 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=From Festivals to the Everyday: The Circulation of Kumade at the Tori no Ichi at Hanazono Shrine en-subtitle= kn-subtitle= en-abstract= kn-abstract=Every year in November, the Tori no Ichi festival draws huge crowds to the grounds of Hanazono Shrine in Shinjuku, Tokyo. The festival is centered around the buying and selling of kumade, or good luck rakes. These bold and colorful objects function as engimono, or good luck charms, purchased for business prosperity or home safety. This study explores the circulation and itinerary of kumade at the Tori no Ichi festival by analyzing the performances surrounding them. While previous scholarship on engimono has focused on their roles in domestic settings or disposal rituals, this research approaches them in situ at the festival. The study shows that these objects bridge the festival and the everyday, connecting people to the event and the sacred site through a dynamic network of social, spatial, and ritual practices. The research draws on fieldwork and in-depth interviews conducted at Hanazono Shrine between 2020 and 2024. en-copyright= kn-copyright= en-aut-name=TILLONENMia en-aut-sei=TILLONEN en-aut-mei=Mia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of English Language and Culture, FUJI WOMEN’S UNIVERSITY kn-affil= en-keyword=urban festival kn-keyword=urban festival en-keyword=material religion kn-keyword=material religion en-keyword=sacred object kn-keyword=sacred object en-keyword=performance kn-keyword=performance en-keyword=Tokyo kn-keyword=Tokyo END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=1 end-page=19 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The “Russian Flu” pandemic in Japan, 1889-1891: A social-historical perspective kn-title=日本における「ロシアかぜ」流行の社会史的分析 ―1889 -1891 年パンデミックと日本社会― en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study offers a social-historical analysis of the “Russian flu” pandemic in Japan (1889?1891). Due to scarce statistical data, the study relies primarily on contemporary newspapers and magazines. It identifies two distinct epidemic waves: the first in spring-summer 1890, and the second from late 1890 to spring 1891. The first wave, though widespread, was overshadowed by a concurrent cholera epidemic and caused relatively few deaths, whereas the second wave was far more lethal and generated widespread fear. At the time, influenza remained an “unknown disease”, with unclear etiology and no established treatments. People responded with diverse measures, from purchasing patent medicines and using folk remedies to symbolic practices such as "disease naming" (osome-kaze). The crisis also renewed attention to historical records of earlier influenza-like epidemics in Japan. In contrast, by the time of the later “Spanish flu” pandemic, advances in bacteriology had already rendered influenza a medically defined disease. This comparison highlights how shifting medical knowledge shaped societal responses. The findings not only corroborate previous excess-mortality analyses but also provide new historical insights into how societies have historically confronted pandemics. en-copyright= kn-copyright= en-aut-name=KAWAUCHIAtsushi en-aut-sei=KAWAUCHI en-aut-mei=Atsushi kn-aut-name=川内淳史 kn-aut-sei=川内 kn-aut-mei=淳史 aut-affil-num=1 ORCID= affil-num=1 en-affil=Uehiro Disaster Risk Reduction Research Division, International Research Institute of Disaster Science (IRIDeS), TOHOKU UNIVERSITY kn-affil= en-keyword=Russian flu kn-keyword=Russian flu en-keyword=influenza pandemic kn-keyword=influenza pandemic en-keyword=epidemic waves kn-keyword=epidemic waves en-keyword=social history kn-keyword=social history en-keyword=unknown disease kn-keyword=unknown disease en-keyword=modern Japan kn-keyword=modern Japan END start-ver=1.4 cd-journal=joma no-vol=153 cd-vols= no-issue=3 article-no= start-page=191 end-page=199 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260114 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of Schizophrenia Spectrum Disorders on the Receipt of Invasive and Systemic Therapy for Colorectal Cancer: A Nationwide Multicenter Retrospective Cohort Study in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: This study examined treatment disparities for colorectal cancer among patients diagnosed with schizophrenia spectrum disorders (SSD), focusing on invasive treatments and stage-appropriate systemic therapy within a universal healthcare system.
Method: In this nationwide retrospective cohort study (2018?2021), we identified 248,966 colorectal cancer patients, including 2337 diagnosed with SSD, using linked cancer registry and insurance claims data in Japan. The presence of SSD was classified according to ICD-10 codes F20?29. We used multivariable logistic regression to compare the odds of receiving stage-appropriate adjuvant chemotherapy and systemic therapy, as well as the odds of receiving surgical or endoscopic treatments, between the two groups. The analysis adjusted for age, sex, clinical stage, and scores on the Charlson Comorbidity Index and Barthel Index.

However, there is a lack of evidence regarding its perioperative management. Methods: This retrospective case series included nine patients with RA who underwent a total of 12 either RA-related (n = 9) or unrelated (n = 3) orthopaedic procedures. We reviewed patient demographics, surgical procedures, perioperative OZR discontinuation periods, and postoperative complications. Results: The mean preoperative OZR discontinuation period was 15.8 days (range, 2?25 days). Sutures were removed at a mean of 12.8 days postoperatively (range, 11?14 days) after adequate wound healing had been confirmed. The mean total discontinuation period was 34.9 days (range, 27?43 days). No cases of surgical site infection (SSI) or delayed wound healing (DWH) were observed during a minimum follow-up period of three months. One patient experienced a disease flare before OZR was restarted. Conclusions: Preoperative OZR discontinuation for up to four weeks appeared to be safe in this cohort. These findings may assist orthopaedic surgeons in determining an appropriate perioperative discontinuation strategy for OZR that minimises SSI and DWH risk while reducing the likelihood of RA flare. en-copyright= kn-copyright= en-aut-name=NishidaKeiichiro en-aut-sei=Nishida en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=HaradaRyozo en-aut-sei=Harada en-aut-mei=Ryozo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=HoritaMasahiro en-aut-sei=Horita en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NatsumedaMasamitsu en-aut-sei=Natsumeda en-aut-mei=Masamitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=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=Locomotive Pain Center, Faculty of Medical Development Field, Okayama University kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama City Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Kurashiki Sweet Hospital kn-affil= affil-num=4 en-affil=Locomotive Pain Center, Faculty of Medical Development Field, Okayama University kn-affil= affil-num=5 en-affil=Locomotive Pain Center, Faculty of Medical Development Field, Okayama University kn-affil= affil-num=6 en-affil=Rheumatic Disease Center, Mabi Memorial Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=delayed wound healing kn-keyword=delayed wound healing en-keyword=discontinuation kn-keyword=discontinuation en-keyword=ozoralizumab kn-keyword=ozoralizumab en-keyword=orthopaedic surgery kn-keyword=orthopaedic surgery en-keyword=perioperative management kn-keyword=perioperative management en-keyword=rheumatoid arthritis kn-keyword=rheumatoid arthritis en-keyword=surgical site infection kn-keyword=surgical site infection END start-ver=1.4 cd-journal=joma no-vol=178 cd-vols= no-issue=1 article-no= start-page=e70775 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reactive Carbonyl Species Mediate Isothiocyanate Signaling Pathway in Arabidopsis thaliana Guard Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Our previous results demonstrated that depletion of glutathione (GSH) rather than elevation of levels of reactive oxygen species (ROS) is highly correlated with the decrease in stomatal aperture induced by isothiocyanates (ITCs), although ROS is considered a key second messenger in stomatal closure, suggesting that another signal component regulates stomatal apertures along with GSH depletion. This study, using Arabidopsis, clarified that reactive carbonyl species (RCS), especially acrolein and 4-hydroxy-(E)-2-nonenal, are determinants of stomatal aperture responses to ITCs. All tested ITCs, allyl isothiocyanate (AITC), sulforaphane (SFN), benzyl isothiocyanate (BITC), and phenethyl isothiocyanate (PEITC), significantly induced stomatal closure, which was inhibited by the RCS scavengers, carnosine and pyridoxamine. The RCS scavengers suppressed ITC-induced depletion of GSH but not elevation of ROS levels. All tested ITCs (AITC, SFN, BITC, and PEITC) increased levels of RCS and non-RCS aldehydes in the epidermal tissues. However, acrolein, 4-hydroxy-(E)-2-nonenal, crotonaldehyde, and (E)-2-pentenal induced stomatal closure at 10 and 100?μM, whereas propionaldehyde, butyraldehyde, and n-pentanal did not at concentrations up to 100?μM. Acrolein and 4-hydroxy-(E)-2-nonenal more effectively induced stomatal closure and GSH depletion than crotonaldehyde and (E)-2-pentenal did. The contents of RCS were more strongly correlated with GSH levels and stomatal closure than with ROS levels. These results suggest that RCS, especially acrolein and 4-hydroxy-(E)-2-nonenal, acts as key regulators of stomatal closure in guard cells in response to ITCs. en-copyright= kn-copyright= en-aut-name=FarzanaSumaiya en-aut-sei=Farzana en-aut-mei=Sumaiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IslamMd.

Additive manufacturing (AM) enables controlled surface morphology, which may enhance micromechanical retention without additional treatments. Methods: Zirconia specimens with three AM-derived surface designs?(1) concave?convex hemispherical patterns, (2) concave hemispherical patterns, and (3) as-printed surfaces?were fabricated using a slurry-based 3D printing system and sintered at 1500 °C. Zirconia specimens fabricated by subtractive manufacturing using CAD/CAM systems, polished with 15 ?m diamond lapping film and with or without subsequent alumina sandblasting, served as controls. Surface morphology was analyzed by FE-SEM, and shear bond strength (SBS) was tested after cementation with a resin-based luting agent. Results: SEM revealed regular layered textures and designed hemispherical structures (~300 ?m) in AM specimens, along with step-like irregularities (~40 ?m) at layer boundaries. The concave?convex AM group showed significantly higher SBS than both sandblasted and polished subtractive-manufactured zirconia (p < 0.05). Vertically printed specimens demonstrated greater bonding strength than those printed parallel to the bonding surface, indicating that build orientation affects resin infiltration and interlocking. Conclusion: AM-derived zirconia surfaces can provide superior and reproducible micromechanical retention compared with conventional treatments. Further optimization of printing parameters and evaluation of long-term durability are needed for clinical application. en-copyright= kn-copyright= en-aut-name=YoshiharaKumiko en-aut-sei=Yoshihara en-aut-mei=Kumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=LeeSungho en-aut-sei=Lee en-aut-mei=Sungho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaruoYukinori en-aut-sei=Maruo en-aut-mei=Yukinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SpirrettFiona en-aut-sei=Spirrett en-aut-mei=Fiona kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KiriharaSoshu en-aut-sei=Kirihara en-aut-mei=Soshu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=Van MeerbeekBart en-aut-sei=Van Meerbeek en-aut-mei=Bart kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=National Institute of Advanced Industrial Science and Technology (AIST), Health and Medical Research Institute kn-affil= affil-num=2 en-affil=Advanced Research Center for Oral and Craniofacial Sciences, Okayama University Dental School kn-affil= affil-num=3 en-affil=National Institute of Advanced Industrial Science and Technology (AIST) kn-affil= affil-num=4 en-affil=Department of Prosthodontics, Okayama University kn-affil= affil-num=5 en-affil=Joining and Welding Research Institute, Osaka University kn-affil= affil-num=6 en-affil=Joining and Welding Research Institute, Osaka University kn-affil= affil-num=7 en-affil=Department of Biomaterials and Bioengineering, Faculty of Dental Medicine, Hokkaido University kn-affil= affil-num=8 en-affil=Department of Oral Health Sciences, BIOMAT, KU Leuven kn-affil= en-keyword=additive manufacturing kn-keyword=additive manufacturing en-keyword=bond strength kn-keyword=bond strength en-keyword=dental crown kn-keyword=dental crown en-keyword=dental resin cement kn-keyword=dental resin cement en-keyword=dental zirconia kn-keyword=dental zirconia 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=2026 dt-pub=20260201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Does Human Depopulation Reduce Resource Consumption??Evidence from Anthropocene Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Humanity’s deepening strain on Earth systems has sparked widespread discussion of an “Anthropocene crisis,” often attributed to overpopulation. This raises the question: if overpopulation underpins the crisis, does its resolution lie in depopulation? Here, we examine the effects of Japan’s ongoing depopulation on the nexus of population, economy, cropland use, food, water, and energy. We take a systematic Bayesian approach to examine changes in the strength and direction of causality among these variables and explore plausible future pathways under Shared Socioeconomic Pathway (SSP) scenarios. We find that, while depopulation has led to reductions in resource demand, notably for water and energy, impacts on the food system are more complex due to interdependencies with economic and other factors beyond population change. In conclusion, we argue that it will take longer than predicted for depopulation dividends to materialize at a scale that could meaningfully contribute to addressing the crisis, and that proactive efforts to reshape consumption patterns and restructure economic systems, from a model predicated on perpetual growth to one oriented toward sufficiency, are necessary to capitalize on the potential dividends offered by this demographic shift. en-copyright= kn-copyright= en-aut-name=BarrahmouneAnass en-aut-sei=Barrahmoune en-aut-mei=Anass kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatanlePeter en-aut-sei=Matanle en-aut-mei=Peter kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KimJiyoung en-aut-sei=Kim en-aut-mei=Jiyoung kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Humanities and Social Sciences, Faculty of Economics, Okayama University kn-affil= affil-num=2 en-affil=School of East Asian Studies, The University of Sheffield kn-affil= affil-num=3 en-affil=Graduate School of Humanities and Social Sciences, Faculty of Economics, Okayama University kn-affil= en-keyword=Anthropocene crisis kn-keyword=Anthropocene crisis en-keyword=Depopulation dividend kn-keyword=Depopulation dividend en-keyword=Population kn-keyword=Population en-keyword=Overpopulation kn-keyword=Overpopulation en-keyword=Resource nexus kn-keyword=Resource nexus en-keyword=Bayesian analysis kn-keyword=Bayesian analysis END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=4 article-no= start-page=300 end-page=309 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20130222 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis of biopterin and related pterin glycosides en-subtitle= kn-subtitle= en-abstract= kn-abstract=Certain pterins having a hydroxyalkyl side chain at C-6 have been found as glycosidic forms in certain prokaryotes, such as 2′-O-(α-D-glucopyranosyl)biopterin from various kinds of cyanobacteria, and limipterin from a green sulfur photosynthetic bacterium.

Sliding tests using SiC ceramic balls in normal saline revealed that the coating exhibited a low friction coefficient of 0.05-0.06 at a shorter running-in process than SiC bulk ceramic plates. The specific wear rate of the coating was also lower than that of the SiC plate. Reactive molecular dynamics simulations revealed that the C?Si?O bonds in the coating facilitated the generation of Si?O units, which contained Si?O bonds but no Si-C bonds, through tribochemical reactions with water, resulting in superior tribological properties in normal saline compared to those of SiC plates. These findings demonstrate that a-SiC-based coatings containing C?Si?O bonds are promising as low-friction and low-wear coatings for biomedical implants such as ceramic joint prostheses. en-copyright= kn-copyright= en-aut-name=ShiotaTadashi en-aut-sei=Shiota en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TaniyaDaiki en-aut-sei=Taniya en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimazakiKazuma en-aut-sei=Shimazaki en-aut-mei=Kazuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakanoChiyu en-aut-sei=Nakano en-aut-mei=Chiyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OmiyaYuya en-aut-sei=Omiya en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiiMasahiro en-aut-sei=Fujii en-aut-mei=Masahiro 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=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=Department of Comprehensive Technical Solutions, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=silicon carbide kn-keyword=silicon carbide en-keyword=amorphous kn-keyword=amorphous en-keyword=coating kn-keyword=coating en-keyword=water lubrication kn-keyword=water lubrication en-keyword=ceramic artificial joint kn-keyword=ceramic artificial joint END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=3 article-no= start-page=e80971 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250321 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prospective Evaluation of the Safety and Compression Performance of Novel Compression Denim Jeans in Healthy Volunteers and Patients With Lymphedema en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: The treatment of lower-extremity lymphedema, whether congenital or acquired, remains challenging. Long-term management aimed at reducing complications and maximizing quality of life is essential. Compression stockings are crucial in this management; however, their application is limited by patient experience (ease of wear, texture, breathability, and appearance). This highlights the need to evaluate alternative compression garments that maintain therapeutic efficacy while improving patient adherence.
Methods: We developed a novel compression denim product (Flow plus Jeans?) using advanced sewing technology. Its baseline performance (compression ability) was evaluated by measuring pressure gradients at three points (ankle, calf, and thigh) using a mannequin-based compression testing system and compared with those of existing stockings. Thereafter, a safety assessment was conducted on healthy volunteers to evaluate potential adverse effects, including changes in lower limb circumference, signs of deep vein thrombosis (DVT) via ultrasound, and skin complications. A clinical trial in patients with lymphedema was then performed to compare its efficacy with that of conventional compression stockings.
Results: Baseline performance testing with a mannequin revealed that Flow plus Jeans demonstrated compression levels and pressure gradients at three calf points comparable to those of standard compression stockings. A safety study involving nine healthy volunteers confirmed that Flow plus Jeans caused no significant changes in lower-limb circumferences after three days of wear, with no cases of DVT or skin complications. In a subsequent clinical trial involving nine female patients with lymphedema, the jeans showed non-inferiority to existing stockings concerning lower-limb circumference measurements at six points (pre-use vs. six months post-use), with patient-reported experiences assessed via questionnaires. Notably, patients reported enhanced satisfaction regarding the jeans' fashionability, which could serve as an incentive for long-term adherence.
Conclusion: Our findings suggest that Flow plus Jeans represent a promising novel option for the long-term management of lymphedema, offering an alternative that balances medical efficiency with improved patient satisfaction and demonstrates safety in healthy individuals. en-copyright= kn-copyright= en-aut-name=OusakaDaiki en-aut-sei=Ousaka en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamadaKiyoshi en-aut-sei=Yamada en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakanoNoriko en-aut-sei=Sakano en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=MiyakeKazumasa en-aut-sei=Miyake en-aut-mei=Kazumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakahashiTakumi en-aut-sei=Takahashi en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuokaAkihiro en-aut-sei=Matsuoka en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamadaShintaro en-aut-sei=Yamada en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShinaokaAkira en-aut-sei=Shinaoka en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OozawaSusumu en-aut-sei=Oozawa en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Departments of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Rehabilitation, Lymphedema Treatment Center, Kousei Hospital kn-affil= affil-num=6 en-affil=Division of Business Management, Matsuoka Corporation kn-affil= affil-num=7 en-affil=Division of Production Engineering, Matsuoka Corporation kn-affil= affil-num=8 en-affil=Division of Sales, Kaihara Corporation kn-affil= affil-num=9 en-affil=Department of Lymphatics and Edematology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Clinical Safety, Okayama University Hospital kn-affil= en-keyword=compression garments kn-keyword=compression garments en-keyword=denim jeans kn-keyword=denim jeans en-keyword=long-term management kn-keyword=long-term management en-keyword=lower-extremity lymphedema kn-keyword=lower-extremity lymphedema en-keyword=quality of life kn-keyword=quality of life 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=2026 dt-pub=20260119 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A retrospective cohort study comparing periodontal regeneration using fibroblast growth factor‐2 versus autologous bone graft en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Fibroblast growth factor-2 (FGF-2) is a novel agent utilized in periodontal regeneration therapy. However, its clinical efficacy compared with autologous bone graft (ABG), a long-established treatment, remains unclear. This study aimed to compare the clinical outcomes of FGF-2 and ABG and to assess the impact of patient background factors on outcomes when using FGF-2.
Methods: We collected the subjects from January 2013 to September 2023. Clinical outcomes included the vertical bone defect improvement rate (VBDIR) and the probing pocket depth improvement (PPDI). Clinical outcomes between the two groups were compared using analysis of covariance (ANCOVA), adjusting for age, sex, smoking history, and hypertension. Additionally, a multilevel linear analysis was performed to assess factors influencing outcomes in FGF-2.
Results: A total of 180 sites from 141 patients (FGF-2: 150 sites; ABG: 30 sites) were evaluated. Both VBDIR and PPDI significantly improved postoperatively in both groups. There were no significant differences in clinical outcomes between FGF-2 and ABG. In FGF-2, smoking history was positively associated, while the preoperative bone defect angle (BDA) was negatively associated with clinical outcomes.
Conclusions: FGF-2 might exhibit clinical outcomes comparable to those of ABG, suggesting it is a clinically viable alternative for vertical bone defects. When using FGF-2, patient-specific factors such as smoking history and preoperative BDA should be considered carefully.

The pathophysiology involves fluid leakage from the choroidal capillaries, known as the choriocapillaris, into the subretinal space through sites of damage in the retinal pigment epithelium. This case report discusses the underlying causes of central serous chorioretinopathy-like findings in minimal change nephrotic syndrome.

The patient was a 33-year-old woman who developed nephrotic syndrome that was confirmed to be minimal change disease by renal biopsy. She experienced two major relapses of nephrotic syndrome at the ages of 36 and 41 years. She also had a minor relapse at the age of 37 years, five months after the first major relapse at the age of 36 years, as well as four additional minor relapses at the ages of 44, 46, 50, and 51 years. The onset of central serous chorioretinopathy-like manifestations, which were localized to the left eye, occurred three months after the initial onset of nephrotic syndrome at the age of 33 years. Two subsequent episodes of relapse of central serous chorioretinopathy-like manifestations were observed in both eyes at intervals of five months and one month, respectively, after major relapses of nephrotic syndrome at the ages of 36 and 41 years. Thereafter, she did not develop further central serous chorioretinopathy-like manifestations.

She discontinued oral prednisolone at the age of 54 years and experienced no further relapses of nephrotic syndrome through her latest visit at the age of 61 years. She maintained normal renal function and good visual acuity in both eyes. The long-term, consistent temporal association between episodes of central serous chorioretinopathy and the onset and relapses of minimal change nephrotic syndrome is strongly supported by longitudinal clinical observations spanning 28 years. This parallel course suggests a possible shared pathophysiological mechanism or common triggering factors underlying both diseases. 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=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology, and Metabolism, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=central serous chorioretinopathy kn-keyword=central serous chorioretinopathy en-keyword=corticosteroid kn-keyword=corticosteroid en-keyword=cyclosporine kn-keyword=cyclosporine en-keyword=fluorescein angiography kn-keyword=fluorescein angiography en-keyword=minimal change disease kn-keyword=minimal change disease en-keyword=minimal change nephrotic syndrome kn-keyword=minimal change nephrotic syndrome en-keyword=photoreceptor ellipsoid zone kn-keyword=photoreceptor ellipsoid zone en-keyword=renal biopsy kn-keyword=renal biopsy en-keyword=steroid-induced retinal pigment epitheliopathy kn-keyword=steroid-induced retinal pigment epitheliopathy en-keyword=steroid pulse therapy kn-keyword=steroid pulse therapy END start-ver=1.4 cd-journal=joma no-vol=2026 cd-vols= no-issue=1 article-no= start-page=7874254 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Experimental Analysis of Automatic Discrimination Performance Between Simulated Bruxism and Non‐Bruxism Under Conscious Conditions Using Electromyography and Machine Learning en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: This study aimed to evaluate the potential use of machine learning to automatically classify electromyography (EMG) data into bruxism simulated movement with tooth contact (BMwTC), bruxism simulated movement without tooth contact (BMwoTC), and non-bruxism movement (non-BM).
Methods: Twelve eligible healthy participants (female/male: 2/10, mean age: 35.3?±?8.4?years) were asked to perform the simulated movements (all the tasks were performed five times for 5?s each with a 30-s rest interval). The electrodes were placed on the masseter, infrahyoid, inframandibular, and chin muscles. A sound sensor was placed adjacent to the masseter. The EMG and sound data were sampled at 1 and 44.1?kHz, respectively. Single- and multi-stream hidden Markov models (HMMs) were used to automatically discriminate the tested behavior from the others using a hamming window with 100?ms and shift length of 50?ms. The leave-one-out method was used for training and testing the model, with data from 11 participants used for training and one for testing. Each participant was evaluated, and the final performance was measured by averaging the results of 12 classification trials. The validity of the discrimination was assessed by calculating the harmony mean values using six EMG signals and the sound data.
Results: The masseter EMG demonstrated significantly higher discrimination accuracy in the single-stream model (p? < 0.05, One-way ANOVA, Tukey HDS). The multi-stream model also demonstrated higher accuracy; however, no significant difference was observed. Notably, the accuracy of BMwoTC was less than 0.5.
Conclusion: The machine-learning-based discriminative system accurately discriminates BMwTC from non-BM using masseter EMG. en-copyright= kn-copyright= en-aut-name=MinakuchiHajime en-aut-sei=Minakuchi en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NagasakiMitsuhiro en-aut-sei=Nagasaki en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=??nhL?c Ho?ng en-aut-sei=??nh en-aut-mei=L?c Ho?ng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MikiHaruna en-aut-sei=Miki en-aut-mei=Haruna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OmoriKo en-aut-sei=Omori en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishimuraTazuko en-aut-sei=Nishimura en-aut-mei=Tazuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KubokiTakuo en-aut-sei=Kuboki en-aut-mei=Takuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MinematsuNobuaki en-aut-sei=Minematsu en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Electrical Engineering and Information Systems, Graduate School of Engineering, The University of Tokyo kn-affil= affil-num=3 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Electrical Engineering and Information Systems, Graduate School of Engineering, The University of Tokyo kn-affil= affil-num=7 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Electrical Engineering and Information Systems, Graduate School of Engineering, The University of Tokyo kn-affil= en-keyword=bruxism kn-keyword=bruxism en-keyword=dentistry kn-keyword=dentistry en-keyword=electromyography kn-keyword=electromyography en-keyword=EMG discrimination kn-keyword=EMG discrimination en-keyword=machine learning kn-keyword=machine learning END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue= article-no= start-page=105566 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202604 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A semi-quantitative archaeothermometer based on feldspar and volcanic glass compositions in ancient ceramics from the Kibi region, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, we analyzed the chemical compositions of feldspar and volcanic glass clasts in haniwa from kofuns and Sue ware from the Sabukaze kiln site, both in the Kibi region, southwestern Japan, to estimate the thermal conditions of ceramic firing in the 5th?8th centuries CE. Based on the coexistence of molten and unmolten feldspar rims, the solidus temperatures were estimated at ? 1050°C?1150°C for haniwa and ? 1150°C?1200°C for Sue ware. Volcanic glass compositions changed systematically during firing, showing increases in K2O and decreases in Na2O. From these observations, we propose a semi-quantitative archaeothermometer using variations in the K/Na molar ratio of volcanic glass within a ceramic matrix. This approach can be applied to investigate the development of kiln-firing in the Kibi region, the existence of haniwa potters employing different firing methods, variation in heat input for producing Sue vessels of differing sizes or functions, and temperature-controlled practices in Sue ware production. en-copyright= kn-copyright= en-aut-name=NozakaToshio en-aut-sei=Nozaka en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhbayashiNaoya en-aut-sei=Ohbayashi en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TodaYuki en-aut-sei=Toda en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AnamiTaiji en-aut-sei=Anami en-aut-mei=Taiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugiuraKanako en-aut-sei=Sugiura en-aut-mei=Kanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NozakiTakahiro en-aut-sei=Nozaki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KimuraOsamu en-aut-sei=Kimura en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsumotoNaoko en-aut-sei=Matsumoto en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SeikeAkira en-aut-sei=Seike en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Archaeology, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for the Dynamics of Civilizations, Okayama University kn-affil= affil-num=7 en-affil=Research Institute for the Dynamics of Civilizations, Okayama University kn-affil= affil-num=8 en-affil=Research Institute for the Dynamics of Civilizations, Okayama University kn-affil= affil-num=9 en-affil=Department of Archaeology, Okayama University kn-affil= en-keyword=Haniwa kn-keyword=Haniwa en-keyword=Sue ware kn-keyword=Sue ware en-keyword=Firing temperature kn-keyword=Firing temperature en-keyword=Kibi kn-keyword=Kibi en-keyword=Japan kn-keyword=Japan END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=12 article-no= start-page=e095428 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness of education programme to increase competency of health cadres in Indonesia: a cluster non-randomised controlled trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives Health cadres, who assist midwives in supporting pregnant women in community settings, need to enhance their competencies in identifying risk factors and referring high-risk pregnant women to midwives for further care. Since the capabilities of these health cadres are influenced by maternal complications, an educational programme was implemented to strengthen their skills. Therefore, this study aimed to evaluate the competency of health cadres by providing a researcher-developed educational programme.
Design An open-label, cluster non-randomised controlled trial.
Setting and participants Health cadres with at least 1 year of work experience were recruited at six public health centres (PHCs) in Banjarnegara Regency, Indonesia.
Interventions Six PHCs were selected and allocated into intervention group (IG=3 PHCs) and control group (CG=3 PHCs) groups. A total of 133 female health cadres were enrolled across the selected PHCs. At each PHC, a systematic random sampling method was used to select the participants. The researchers and health professionals provided a 3-week period of theoretical and scenario-based simulations to the IG, while the CG received no education.
Outcome measures Researcher-developed questionnaires and checklists were used to assess the knowledge, skills (health assessment, communication, attitude) and confidence. The primary endpoint was competency, a total score of knowledge and skills. The outcome domains were compared between the two groups, and a linear mixed-effect model was used to account for cluster-level variation.
Results A total of 130 (97.7%) completed the study (IG:64, CG:66). The competency score showed significant improvement at endline (CG=49.5?and IG=52.5; p=0.002). The median scores for health assessment skills (CG=12?vs IG=14; p<0.001) and communication skills (CG=7?vs IG=8; p<0.001) were increased in the IG compared with the CG. Mixed-effect model indicated that groups (β (95%?CI) 2.49 (0.57 to 4.41), p=0.012), baseline knowledge (β(95%?CI) 0.73 (0.54 to 0.92), p<0.001) and midline health assessment skills (β (95%?CI) 0.54 (0.25 to 0.82), p<0.001) were significant positive predictors, while age was negatively associated with competency (β (95%?CI) ?0.20 (?0.30 to ?0.10), p<0.001)).
Conclusion Education effectively increased the competency of health cadres. A well-structured education programme is necessary for health cadres to improve and maintain their competencies in monitoring high-risk pregnant women.

In this study, we conducted electrical conductivity (EC) measurements on two samples, the composition of which resemble the partial-melting products atop the 410-km discontinuity and in the lower part of the transition zone. The EC of carbonatite melts was investigated using impedance spectroscopy combined with a multi-anvil press up to 20 GPa. Pressure has a great effect on the EC of the carbonatite melts. While the EC dropped overall by 0.6 log unit from 3 to 20 GPa for varying compositions, the pressure effect becomes weaker above 10 GPa. The Hashin-Shtrikman mixing model indicates that melt fraction of 0?0.3 vol% is necessary to account for the EC atop the 410-km discontinuity beneath NE China, north Philippine Sea, north Pacific, and Australian craton. However, this value soars to 1?4.5 vol% for the lower part of the transition zone in the same regions, and further increases to 3.7?7.3 vol% for cold subduction regions if the slab surface temperature is 300 K lower. The difference in the needed melt fraction at different depths implies that the magnitude of partial melting is much larger in the lower part of the mantle transition zone, and it is thus likely to be the main barrier to the recycled carbonates towards the deep interior. en-copyright= kn-copyright= en-aut-name=ZhaoBin en-aut-sei=Zhao en-aut-mei=Bin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZhuJintao en-aut-sei=Zhu en-aut-mei=Jintao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ChenQi en-aut-sei=Chen en-aut-mei=Qi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshinoTakashi en-aut-sei=Yoshino en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=Center for Advanced Radiation Sources, University of Chicago kn-affil= affil-num=4 en-affil=Institute for Planetary Materials, Okayama University kn-affil= en-keyword=carbon kn-keyword=carbon en-keyword=carbonatite melts kn-keyword=carbonatite melts en-keyword=electrical conductivity kn-keyword=electrical conductivity en-keyword=impedance spectroscopy kn-keyword=impedance spectroscopy en-keyword=multi-anvil press kn-keyword=multi-anvil press END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=12 article-no= start-page=110594 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251216 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Endoscopic features of oral and pharyngolaryngeal papillomas and their role in distinguishing squamous cell carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=BACKGROUND
Oral and pharyngolaryngeal papillomas are occasionally detected during esophagogastroduodenoscopy. However, their endoscopic features have not been sufficiently investigated.
AIM
To distinguish oral and pharyngolaryngeal papillomas from elevated squamous carcinomas, this study examined their endoscopic features.
METHODS
Forty-seven patients with oral or pharyngeal papilloma participated in this study. The endoscopic characteristics of papillomas were identified by focusing on narrowband and blue laser imaging representations.
RESULTS
Papillomas were classified into three patterns based on their endoscopic features: Salmon roe-like polyps, polyps without capillary transparency, and pinecone-like polyps, with salmon roe-like polyps most prevalent (48.9%). We subsequently analyzed features differentiating papillomas and squamous cell carcinomas in the same region and found that squamous cell carcinomas exhibited at least one of the following three features: Uneven or absent lobulated structure, irregular morphology of capillaries, and coexistence of flat lesions. In contrast, papillomas displayed a uniform lobulated structure, homogeneous or non-visible capillaries, and an absence of flat components. When any of these characteristics were present, two endoscopic specialists evaluated the lesions for the diagnosis of squamous cell carcinoma, with sensitivities of 100% and 97.6% and specificities of 68.9% and 93.3%.
CONCLUSION
Understanding distinct endoscopic patterns of oropharyngeal papillomas and squamous cell carcinomas provides valuable guidance to endoscopists performing esophagogastroduodenoscopy. 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=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamadaKenta en-aut-sei=Hamada en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KonoYoshiyasu en-aut-sei=Kono en-aut-mei=Yoshiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KawaharaYoshiro en-aut-sei=Kawahara en-aut-mei=Yoshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pathology, Okayama University Hospital 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 Practical Gastrointestinal Endoscopy, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Esophagogastroduodenoscopy kn-keyword=Esophagogastroduodenoscopy en-keyword=Human papillomavirus kn-keyword=Human papillomavirus en-keyword=Laryngeal polyp kn-keyword=Laryngeal polyp en-keyword=Papilloma kn-keyword=Papilloma en-keyword=Pharyngeal polyp kn-keyword=Pharyngeal polyp 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=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Multi-step mechanisms of early phospholipid hydrolysis and mineralisation unveiled through combined quantum chemical calculations and experimental analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Phospholipids play key roles in bone formation, with phosphatidylserine (PS) reportedly inducing more rapid mineralisation than phosphatidylcholine (PC); however, the underlying mechanisms remains unclear. This study investigated PS and PC mineralisation using experimental methods and computational chemistry. The stationary points in the potential energy surfaces of the reactions were preliminarily found using a neural network potential (PreFerred Potential in Matlantis) capable of predicting the interaction energies for arbitrary combinations of atoms, and then refined through density functional theory calculations (Gaussian16, at the B3LYP/6-31G(d,p) level of theory). When hydrolysis reactions were assumed to be the initial step in the mineralisation of phospholipids, the results were consistent with empirical analysis. PS was found to be more easily hydrolised than PC, primarily owing to the presence of a labile proton in the NH3+ group of serine that facilitates proton transfer, enhancing hydrolysis of PS at lower energy thresholds. Specifically, when a single phospholipid was considered, three distinct hydrolysis routes were identified: between serine (or choline) and phosphate, between glycerol and phosphate, and between an aliphatic carbon chain and the glycerol backbone. In particular, the initial steps of hydrolysis involved the formation of a pentavalent phosphate intermediate. When calculations were performed with two adjacent phospholipid molecules, the loosely bound proton (H+) in the NH3+ group could be readily transferred either to the P?O bond linking serine to the phosphate group; or to the P?O bond connecting the phosphate to glycerol in a neighboring PS6 molecule. These findings reveal the important roles of serine NH3+ in facilitating hydrolysis of PS, and provide insights for designing novel molecules to accelerate bone regeneration. en-copyright= kn-copyright= en-aut-name=ShibataKeisuke en-aut-sei=Shibata en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShiotaniTakahumi en-aut-sei=Shiotani en-aut-mei=Takahumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ChenYunhao en-aut-sei=Chen en-aut-mei=Yunhao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KuriharaReina en-aut-sei=Kurihara en-aut-mei=Reina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamaguchiKatsunori en-aut-sei=Yamaguchi en-aut-mei=Katsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HaraEmilio Satoshi en-aut-sei=Hara en-aut-mei=Emilio Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KunioshiN?lson en-aut-sei=Kunioshi en-aut-mei=N?lson kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Materials Science, Waseda University kn-affil= affil-num=2 en-affil=Department of Resources and Environmental Engineering, Waseda University kn-affil= affil-num=3 en-affil=Department of Materials Science, Waseda University kn-affil= affil-num=4 en-affil=Department of Resources and Environmental Engineering, Waseda University kn-affil= affil-num=5 en-affil=Department of Resources and Environmental Engineering, Waseda University kn-affil= affil-num=6 en-affil=Department of Advanced International and Information Dentistry, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Materials Science, Waseda University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=7 article-no= start-page=102730 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202507 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of full-time equivalent allocation on the effectiveness of antimicrobial stewardship activities: A multicenter study in Okayama, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Optimized administration of antimicrobial agents is critical for mitigating the emergence of antimicrobial resistance. This study aimed to elucidate the relationship between antimicrobial stewardship (AS) activities and antimicrobial prescription trends and patterns.
Methods: This retrospective, multicenter, longitudinal study was conducted between April 2014 and March 2023 (9-year fiscal period). A structured, questionnaire survey, regarding institutional infrastructure and environmental parameters, service modalities provided by AS activities, resource allocation and systemic support, and data on the use of broad-spectrum antimicrobial agents, was distributed to co-investigators working at seven hospitals in Okayama, Japan. Full-time equivalent (FTE) allocation for each healthcare facility were calculated and subsequently compared among the hospitals. Temporal variations in the proportional distribution of broad-spectrum antimicrobial agents were statistically evaluated using joinpoint regression analysis.
Results: Two hospitals where pharmacists were exclusively dedicated to AS activities and met the recommended FTE allocation showed a statistically significant reduction in the proportion of broad-spectrum antibiotic administration, with average annual percentage changes of ?8.0 % (95 % confidence interval [CI]: ?10.5 to ?5.8) and ?3.1 % (95 % CI: ?5.5 to ?0.7), respectively. In contrast, two other hospitals with full-time AS members but insufficient FTE allocation exhibited inconsistent and statistically nonuniform trends. The remaining three healthcare institutions with poorly resourced AS teams demonstrated no statistically significant trends in their broad-spectrum antimicrobial prescriptions.
Conclusion: Our findings uncovered that hospitals with adequate FTE staffing metrics for AS activities exhibited statistically significant downward trends in the consumption of broad-spectrum antimicrobial agents. en-copyright= kn-copyright= en-aut-name=KajitaShiho en-aut-sei=Kajita en-aut-mei=Shiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HagiyaHideharu

dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Assessing the role of folate syntrophy and folate cross-feeding in the pathobiology of infectious-inflamed milieu caused by Fusobacterium nucleatum en-subtitle= kn-subtitle= en-abstract= kn-abstract=Diet and nutrition affect almost every biological process, including multiple chronic diseases, diabetes, and some cancers. However, there are still significant gaps in our understanding of the importance of nutrition and healthy diets in syntrophy with respect to cross-feeding of the microbe-microbe and the microbe-host in the pathobiology of the infectious-inflamed intestinal milieu caused by anaerobic opportunistic bacteria such as Fusobacterium nucleatum (F. nucleatum). We examined the immune outcomes of three-member folate syntrophy and cross-feeding between F. nucleatum bacteria, endogenous folate-producing gut bacteria, and host cells at the host-pathogen interface using a triple co-culture model. T84, THP-1, and Huh7 cells were inoculated with F. nucleatum for 6 h in regular DMEM, DMEM with 9.5 μM folic acid, or with/without a mixture of Bifidobacterium longum subsp. infantis (B. infantis) and Escherichia coli Nissle 1917 (EcN). Cytokine secretion, cometabolite levels (ammonia, indoles), cell viability, and barrier integrity were assessed. F. nucleatum-induced folate depletion was associated with increased IL-1β and IL-6 and decreased IL-22, along with reduced transepithelial electrical resistance (TEER) and cell viability in T84 cells. Folate supplementation mitigated these effects. The mixture of B. infantis and EcN reduced F. nucleatum-induced pro-inflammatory cytokines, increased IL-22, and improved TEER and cell viability. These protective effects were enhanced by the addition of folate. F. nucleatum also elevated ammonia and reduced indoles, effects reversed by B. infantis and EcN. In addition to the intrinsic pathogenicity of harmful bacteria, folate deprivation, microbe?microbe folate syntrophy, and microbe?host folate cross-feeding contribute to the pathobiology of anaerobic opportunistic bacteria and influence the physiological fate of host cells. A combination of B. infantis and EcN modulates the infectious-inflamed interface through a cytoprotective effect and mechanical competitive extrusion of pathogenic F. nucleatum. These results provide potential insights into the mechanisms of early-onset colorectal cancer, and evidently, require future studies using patient-derived organoids and in vivo systems to improve clinical relevance. en-copyright= kn-copyright= en-aut-name=GhadimiDarab en-aut-sei=Ghadimi en-aut-mei=Darab kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Bl?merSophia en-aut-sei=Bl?mer en-aut-mei=Sophia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=?ahin KayaAysel en-aut-sei=?ahin Kaya en-aut-mei=Aysel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Kr?gerSandra en-aut-sei=Kr?ger en-aut-mei=Sandra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=R?ckenChristoph en-aut-sei=R?cken en-aut-mei=Christoph kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Sch?ferHeiner en-aut-sei=Sch?fer en-aut-mei=Heiner kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UchiyamaJumpei en-aut-sei=Uchiyama en-aut-mei=Jumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsuzakiShigenobu en-aut-sei=Matsuzaki en-aut-mei=Shigenobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=BockelmannWilhelm en-aut-sei=Bockelmann en-aut-mei=Wilhelm kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Microbiology and Biotechnology, Max Rubner-Institut kn-affil= affil-num=2 en-affil=Faculty of Medicine, Christian-Albrechts-University of Kiel kn-affil= affil-num=3 en-affil=Department of Nutrition and Dietetics, Faculty of Health Sciences, Antalya Bilim University kn-affil= affil-num=4 en-affil=Institute of Pathology, Kiel University, University Hospital, Schleswig-Holstein kn-affil= affil-num=5 en-affil=Institute of Pathology, Kiel University, University Hospital, Schleswig-Holstein kn-affil= affil-num=6 en-affil=Laboratory of Molecular Gastroenterology & Hepatology, Christian-Albrechts-University & UKSH Campus Kiel 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=Department of Medical Laboratory Science, Faculty of Health Sciences, Kochi Gakuen University kn-affil= affil-num=9 en-affil=Department of Microbiology and Biotechnology, Max Rubner-Institut kn-affil= en-keyword=Nutrition kn-keyword=Nutrition en-keyword=Metaflammation kn-keyword=Metaflammation en-keyword=Folate kn-keyword=Folate en-keyword=Cytokines kn-keyword=Cytokines en-keyword=Infection kn-keyword=Infection en-keyword=Host cells kn-keyword=Host cells END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=11 article-no= start-page=1023 end-page=1032 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=Bioconversion and Metabolic Fate of the n-1 Polyunsaturated Fatty Acids, 6,9,12,15- Hexadecatetraenoic (C16:4 n-1) and 8,11,14,17- Octadecatetraenoic (C18:4 n-1) Acids, in HepG2 Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fish oil contains not only major fatty acids with double bonds at the n-3, n-6, n-7, and n-9 positions but also those with a double bond at the n-1 position, such as 6,9,12,15-hexadecatetraenoic acid (C16:4 n-1; HDTA). However, intracellular bioconversion and metabolic fate of n-1 polyunsaturated fatty acids (PUFA) remain unclear. Therefore, in this study, we aimed to assess the intracellular bioconversion and metabolic fate of HDTA and its metabolite, 8,11,14,17- octadecatetraenoic acid (C18:4 n-1; ODTA), using HepG2 cells. Based on the results of cell viability and cytotoxicity assays for HDTA and ODTA, the concentration of each fatty acid supplemented in the experiments was set at 10 μM. HepG2 cell culture with HDTA revealed C20:4 n-1 as a new HDTA metabolite, along with previously reported ODTA. Our findings suggest that the HDTA taken up by HepG2 cells undergoes elongation to form ODTA and C20:4 n-1. Following supplementation with HDTA, ODTA, and 5,8,11,14,17-eicosapentaenoic acid (C20:5 n-3; EPA), fatty acids disappeared from the culture medium within 24 h. Notably, the total relative level of HDTA and its metabolites, including ODTA and C20:4 n-1 in HDTA- and ODTA-supplemented cells were significantly lower than the total relative level of EPA and its metabolites, including 7,10,13,16,19-docosapentaenoic acid (C22:5 n-3), C24:6 n-3, and 4,7,10,13,16,19-docosahexaenoic acid (C22:6 n-3) in the EPA-supplemented cells. Except for a portion that was intracellularly elongated, most HDTA was taken up by HepG2 cells and may undergo rapid fatty acid β-oxidation. However, RNA-sequencing and real-time polymerase chain reaction analysis revealed no significant changes in fatty acid β-oxidation?related gene expression levels in HDTA-supplemented cells. Collectively, these results provide novel insights into the intracellular bioconversion mechanisms and metabolic fate of HDTA and ODTA in HepG2 cells, suggesting that the metabolic fate of n-1 PUFA is distinct from that of common PUFA. en-copyright= kn-copyright= en-aut-name=SugimotoKoki en-aut-sei=Sugimoto en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiguchiHideto en-aut-sei=Nishiguchi en-aut-mei=Hideto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HosomiRyota en-aut-sei=Hosomi en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanizakiToshifumi en-aut-sei=Tanizaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsushimaTadahiro en-aut-sei=Tsushima en-aut-mei=Tadahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=BabaNaomichi en-aut-sei=Baba en-aut-mei=Naomichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MisawaYoshihisa en-aut-sei=Misawa en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WangZiyi en-aut-sei=Wang en-aut-mei=Ziyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OnoMitsuaki en-aut-sei=Ono en-aut-mei=Mitsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MurakamiYuki en-aut-sei=Murakami en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KandaSeiji en-aut-sei=Kanda en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=FukunagaKenji en-aut-sei=Fukunaga en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Faculty of Food and Nutritional Sciences, Toyo University kn-affil= affil-num=2 en-affil=Faculty of Chemistry, Materials, and Bioengineering, Kansai University kn-affil= affil-num=3 en-affil=Faculty of Chemistry, Materials, and Bioengineering, Kansai University kn-affil= affil-num=4 en-affil=Bizen Chemical Co., Ltd. kn-affil= affil-num=5 en-affil=Bizen Chemical Co., Ltd. kn-affil= affil-num=6 en-affil=Bizen Chemical Co., Ltd. kn-affil= affil-num=7 en-affil=Bizen Chemical Co., Ltd. kn-affil= affil-num=8 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Hygiene and Public Health, Kansai Medical University kn-affil= affil-num=11 en-affil=Department of Hygiene and Public Health, Kansai Medical University kn-affil= affil-num=12 en-affil=Faculty of Chemistry, Materials, and Bioengineering, Kansai University kn-affil= en-keyword=n-1 polyunsaturated fatty acids kn-keyword=n-1 polyunsaturated fatty acids en-keyword=hexadecatetraenoic acid kn-keyword=hexadecatetraenoic acid en-keyword=octadecatetraenoic acid kn-keyword=octadecatetraenoic acid en-keyword=HepG2 kn-keyword=HepG2 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=20251231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficient resuscitation of early-stage viable but non-culturable cells of Vibrio cholerae using treatment with proteolytic enzymes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vibrio cholerae, the etiological agent of cholera, is ubiquitous in environmental brackish waters. Exposure to low water temperatures induces the bacterium to enter a viable but non-culturable (VBNC) state. In this study, a stepwise decrease in water temperature to 4°C was found to delay the transition to the non-culturable state compared to an abrupt temperature drop, suggesting that V. cholerae cells partially adapt to low temperatures. V. cholerae VBNC cells maintained at 4°C gradually lost their ability to revert to a culturable state. However, VBNC cells in the early stage of dormancy were efficiently resuscitated following treatment with proteolytic enzymes, including proteinase K. The abundance of culturable V. cholerae cells in brackish estuarine waters was quantified using the most probable number (MPN)?quantitative polymerase chain reaction (qPCR) method. Although culturable cells were undetectable in samples treated with bovine serum albumin, they were estimated at 93 and 1,500 MPN/mL in two water samples collected on different days and pre-incubated with proteinase K. Similarly, the abundance of Vibrio species increased markedly following treatment with this enzyme. Additionally, cells of Vibrio species were enumerated by the plating method using CHROMagar Vibrio plates. Consistent with the results of the MPN?qPCR method, treatment with proteinase K resulted in over a 100-fold increase in colony formation. Collectively, these findings suggest that treatment with proteinase K is effective for resuscitating and quantifying V. cholerae VBNC cells in environmental water samples. 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=OgasawaraMona en-aut-sei=Ogasawara en-aut-mei=Mona kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NiwakiShiho en-aut-sei=Niwaki en-aut-mei=Shiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SugiharaRena en-aut-sei=Sugihara en-aut-mei=Rena kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= 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=5 ORCID= en-aut-name=ImamuraDaisuke en-aut-sei=Imamura en-aut-mei=Daisuke 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=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Research Institute of Nursing Care for People and Community, University of Hyogo kn-affil= affil-num=6 en-affil=Research Center for Intestinal Health Science, Okayama University kn-affil= en-keyword=Vibrio cholerae kn-keyword=Vibrio cholerae en-keyword=viable but non-culturable kn-keyword=viable but non-culturable en-keyword=VBNC kn-keyword=VBNC en-keyword=protease kn-keyword=protease en-keyword=proteolytic enzyme kn-keyword=proteolytic enzyme END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=29639 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250813 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Single cell spatial transcriptomics links Wnt signaling disruption to extracellular matrix development in a cleft palate model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Despite advances in understanding the morphological disruptions that lead to defects in palate formation, the precise perturbations within the signaling microenvironment of palatal clefts remain poorly understood. To explore in greater depth the genomic basis of palatal clefts, we designed and implemented the first single cell spatial RNA-sequencing study in a cleft palate model, utilizing the Pax9?/? murine model at multiple developmental timepoints, which exhibits a consistent cleft palate defect. Visium HD, an emerging platform for true single-cell resolution spatially resolved transcriptomics, was employed using custom bins of 2?×?2 μm spatial gene expression data. Validation of spatial gene expression was then validated using custom designed Xenium In Situ mRNA spatial profiling and RNAscope Multiplex assays. Functional enrichment analysis revealed a palate cell-specific perturbation in Wnt signaling effector function in tandem with disrupted expression of extracellular matrix genes in developing mesenchyme. As a key step toward laying the framework for identifying key molecular targets these data can be used for translational studies aimed at developing effective therapies for human palatal clefts. en-copyright= kn-copyright= en-aut-name=Pi?aJeremie Oliver en-aut-sei=Pi?a en-aut-mei=Jeremie Oliver kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=RajuResmi en-aut-sei=Raju en-aut-mei=Resmi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=StipanoEvan en-aut-sei=Stipano en-aut-mei=Evan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MyoAye Chan en-aut-sei=Myo en-aut-mei=Aye Chan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WangZiyi en-aut-sei=Wang en-aut-mei=Ziyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OnoMitsuaki en-aut-sei=Ono en-aut-mei=Mitsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ChattarajParna en-aut-sei=Chattaraj en-aut-mei=Parna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FurukawaMasae en-aut-sei=Furukawa en-aut-mei=Masae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=D’SouzaRena N. en-aut-sei=D’Souza en-aut-mei=Rena N. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Section on Craniofacial Genetic Disorders, Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health (NIH) kn-affil= affil-num=2 en-affil=Section on Craniofacial Genetic Disorders, Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health (NIH) kn-affil= affil-num=3 en-affil=Section on Craniofacial Genetic Disorders, Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health (NIH) kn-affil= affil-num=4 en-affil=Section on Craniofacial Genetic Disorders, Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health (NIH) kn-affil= affil-num=5 en-affil=Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Department of Molecular Biology and Biochemistry, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Department of Molecular Biology and Biochemistry, Okayama University kn-affil= affil-num=7 en-affil=Section on Craniofacial Genetic Disorders, Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health (NIH) kn-affil= affil-num=8 en-affil=Section on Craniofacial Genetic Disorders, Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health (NIH) kn-affil= affil-num=9 en-affil=Section on Craniofacial Genetic Disorders, Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health (NIH) kn-affil= en-keyword=Spatial biology kn-keyword=Spatial biology en-keyword=Cleft palate kn-keyword=Cleft palate en-keyword=Genomics kn-keyword=Genomics en-keyword=Single cell kn-keyword=Single cell en-keyword=Gene expression kn-keyword=Gene expression en-keyword=Profiling kn-keyword=Profiling en-keyword=Extracellular matrix kn-keyword=Extracellular matrix en-keyword=Wnt kn-keyword=Wnt en-keyword=Transcriptome kn-keyword=Transcriptome END start-ver=1.4 cd-journal=joma no-vol=82 cd-vols= no-issue=2 article-no= start-page=E82 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Crystal structure of tris[4-(3,4-dimethoxythiophen-2-yl)phenyl]amine en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the title compound tris?[4-(3,4-di?meth?oxy?thio?phen-2-yl)phen?yl]amine (DMOT-TPA), C36H33NO6S3, the central nitro?gen atom shows no pyramidalization, with the three para-phenyl?ene rings arranged in a propeller-like geometry. Each thio?phene ring is twisted by about 25?29° relative to the adjacent phenyl?ene ring, giving a distorted π-conjugated framework. In the crystal, mol?ecules are linked through multiple C?H?π inter?actions into two-dimensional sheets, which extend into a three-dimensional network. A Cambridge Structural Database survey revealed no prior examples of tri?phenyl?amines bearing 3,4-di?meth?oxy?thio?phen units at the para positions.

In Japan, GIS-based evacuation maps are commonly used to support disaster preparedness, but they still have several limitations. In particular, they do not avoid flooded road segments and cannot generate multiple evacuation options at the same time. This study proposes an improved evacuation route method using the free and open-source software QGIS. The method combines flood-depth data with road network processing to remove roads where the predicted water depth is higher than 0.5 m. It also provides several evacuation paths to different shelters at the same time. A case study in Kurashiki City, Okayama Prefecture, demonstrates that about 1.37% of the road network becomes unusable during an inland-flood scenario. Several existing evacuation routes also pass through hazardous areas, but the QGIS-based method avoids these areas in most cases. Since the workflow uses only built-in QGIS functions and does not require programming or plug-ins, it is easy to reproduce and apply in other regions. This study offers a practical and low-cost method to support inland-flood evacuation planning for local governments. en-copyright= kn-copyright= en-aut-name=PanWenliang en-aut-sei=Pan en-aut-mei=Wenliang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PanShijun en-aut-sei=Pan en-aut-mei=Shijun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanetoJunko en-aut-sei=Kaneto en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaKeisuke en-aut-sei=Yoshida en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishiyamaSatoshi en-aut-sei=Nishiyama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=evacuation route kn-keyword=evacuation route en-keyword=hazard mapping kn-keyword=hazard mapping en-keyword=inland flood kn-keyword=inland flood en-keyword=land use analysis kn-keyword=land use analysis en-keyword=QGIS kn-keyword=QGIS END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=4 article-no= start-page=1041 end-page=1054 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250904 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Asian Subgroup Analysis of Patients in the Phase 2 DeLLphi-301 Study of Tarlatamab for Previously Treated Small Cell Lung Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Tarlatamab is a bispecific T-cell engager (BiTE?) immunotherapy that binds delta-like ligand 3 on the surface of small cell lung cancer (SCLC) cells and CD3 on T cells, facilitating T cell-mediated cancer cell lysis. In the primary analysis of the phase 2 DeLLphi-301 study (NCT05060016), tarlatamab showed a favourable benefit-to-risk profile with durable objective responses and promising survival outcomes in patients with previously treated SCLC. Here, phase 2 data for the Asia region subgroup are presented.
Methods: Patients with previously treated, advanced SCLC received 10 mg tarlatamab every 2 weeks. The primary endpoint was objective response rate (ORR) by blinded independent central review (RECIST version 1.1). Key secondary endpoints included duration of response (DOR), progression-free survival (PFS), overall survival (OS) and safety. The present analysis includes patients enrolled at sites in Asia.
Results: A total of 43 patients were enrolled at sites in Asia. ORR was 46.3% (95% confidence interval [CI], 30.7?62.6) and median DOR was 7.2 months (95% CI 3.9 to not estimable). The median follow-up was 16.6 months for PFS and 21.2 months for OS. Median PFS was 5.4 months (95% CI 3.0?8.1) and median OS was 19.0 months (95% CI 11.4 to not estimable). The most common treatment-emergent adverse event (AE) was cytokine release syndrome (48.8%), and all such events were grade 1 or 2. There were no discontinuations due to treatment-related AEs.
Conclusions: Tarlatamab demonstrated durable responses and promising survival outcomes with a manageable safety profile in this post hoc analysis of patients from Asia with previously treated SCLC.

While daytime bladder control typically precedes nighttime continence, the temporal relationship between early daytime bladder control and subsequent bedwetting remains unclear. We investigated whether daytime bladder control status at age 2.5?years?as indicated by diaper use?is associated with bedwetting at age 4.5?years in a Japanese nationwide cohort.
Methods: We analyzed data from the Japanese Longitudinal Survey of Newborns in the 21st Century (2010 cohort). Daytime bladder control was assessed at age 2.5?years through caregiver-reported diaper use, and bedwetting frequency at age 4.5?years through parental questionnaires. Modified Poisson regression estimated risk ratios (RRs), adjusting for birth-related factors, socioeconomic status, daycare attendance, and developmental milestones.
Results: Among 32?168 children, 26?651 (82.8%) still used diapers at 2.5?years. Bedwetting prevalence at 4.5?years was 42.2%: 34.5% in children who achieved daytime bladder control at 2.5?years versus 43.9% in those still using diapers. After multivariable adjustment, incomplete daytime bladder control at 2.5?years was associated with higher bedwetting risk (adjusted RR 1.25; 95% CI, 1.20?1.31). Multinomial regression revealed dose?response relationships: odds ratios 1.41 (95% CI, 1.30?1.52) for “sometimes” and 1.58 (95% CI, 1.42?1.77) for “often” bedwetting.
Conclusions: Daytime bladder control status at 2.5?years was associated with a 25% increased bedwetting risk at 4.5?years. This association likely reflects individual differences in bladder control maturation rather than causal effects. While daytime bladder control may serve as a developmental marker, its validity as an intervention target remains unestablished. en-copyright= kn-copyright= en-aut-name=MoriwakeTakatoshi

kn-title=Time to positivity for differentiating blood culture contamination: A 20-hour cutoff for major contaminants en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Blood culture remains the gold standard for diagnosing bacteremia; however, contamination inevitably occurs in 2-3% of cases, requiring differentiation between true bacteremia and contamination. Although time to positivity (TTP) aids in this clinical decision, with detection after 24 hours generally indicating contamination, technological advances in blood culture systems may have shortened this threshold interval.
Methods: This study retrospectively analyzed blood culture data in our hospital from April 2023 to January 2025 to determine the optimal TTP cutoff. Patients with positive blood cultures for major contaminating bacteria were included. Cases were classified as true bacteremia or contamination based on a comprehensive chart review conducted by the antimicrobial stewardship audit, and TTP was compared between the groups. Sensitivity, specificity, and Youden index at various TTP cutoffs were utilized to determine the optimal threshold using the receiver operating characteristic curve analysis.
Results: Seventy-one patients were enrolled, with 34 cases classified as true bacteremia and 37 as contamination. Identified bacteria included coagulase-negative staphylococci (70.4%), viridans group streptococci (18.3%), and others (11.3%). The median TTP was significantly shorter in the true bacteremia group compared with the contamination group (18.6 vs.25.8 hours, p < 0.001). In the contamination group, 43.2% of the cases demonstrated positive growth within 24 hours. Based on sensitivity, specificity, and Youden index, the optimal threshold was estimated to be 20 hours. A subgroup analysis of the CNS-only cohort yielded concordant results.
Conclusion: This study suggests that a 20-hour TTP threshold could help effectively differentiate true bacteremia from contamination in current clinical settings. en-copyright= kn-copyright= en-aut-name=ManabeYohei en-aut-sei=Manabe en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakamotoKenta en-aut-sei=Nakamoto en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OguniKohei en-aut-sei=Oguni en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AkazawaHidemasa en-aut-sei=Akazawa en-aut-mei=Hidemasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujitaYasushi en-aut-sei=Fujita en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KiguchiTakashi en-aut-sei=Kiguchi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IioKoji en-aut-sei=Iio en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Nursing, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Nursing, Okayama University Hospital kn-affil= affil-num=9 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= en-keyword=Bacteremia kn-keyword=Bacteremia en-keyword=Blood stream infection kn-keyword=Blood stream infection en-keyword=Contamination kn-keyword=Contamination en-keyword=Incubation time kn-keyword=Incubation time en-keyword=Time to positivity kn-keyword=Time to positivity END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=6 article-no= start-page=00362-2025 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Global trends in idiopathic pulmonary fibrosis mortality rates during 2001?2022 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive and ultimately fatal lung disease. Updated global mortality data, especially from underexplored countries, are limited. This study aimed to understand the current global trends in IPF-associated mortality rates.
Methods This observational study used the World Health Organization Mortality Database to analyse data stratified by sex, age and geographic region, encompassing 64 countries between 2001 and 2022. IPF was defined according to the International Code for Diseases-10 code J84.1. Crude and age-standardised mortality rates per 100?000 individuals were calculated to estimate long-term mortality trends. Mortality rates were calculated by dividing IPF-associated deaths by the corresponding population, with age-specific rates determined for each 5-year age group. Trends in the 2001?2022 period were analysed using a locally weighted regression model, and the average annual percentage change in mortality rates between 2010 and 2022 was estimated using joinpoint regression analysis.
Results Overall, 874?998 deaths associated with IPF were analysed. The LOESS-smoothed crude mortality rate increased from 2.10 (95% confidence interval (CI) 1.77?2.43) per 100?000 in 2001 to 3.14 (95% CI 2.71?3.57) per 100?000 by 2022. The LOESS-smoothed age-standardised mortality rates increased overall, peaking at 1.59 (95% CI 1.51?1.67) per 100?000 in 2018 and declining slightly to 1.57 (95% CI 1.35?1.79) per 100?000 in 2022. Mortality was higher among males than females; furthermore, 87.5% of deaths occurred in individuals aged ?65?years. Mortality rates were highest among the American population, with a notable increase in Latin American countries.
Conclusion IPF-associated mortality rates have increased globally, particularly in males. Significant geographical, age and sex disparities were observed, emphasising the need for targeted public health measures and improved disease management. en-copyright= kn-copyright= en-aut-name=HaradaKo en-aut-sei=Harada en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=VuQuynh Thi en-aut-sei=Vu en-aut-mei=Quynh Thi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoMaki en-aut-sei=Yamamoto en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KoyamaToshihiro en-aut-sei=Koyama en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Brookdale Department of Geriatrics and Palliative Medicine, Icahn School of Medicine at Mount Sinai kn-affil= affil-num=2 en-affil=Division of Hematology/Oncology, Mayo Clinic kn-affil= affil-num=3 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol=190 cd-vols= no-issue=6 article-no= start-page=90 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250922 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prognostic Value of Serum (1→3)-β-D-Glucan Levels in Patients with Candidemia Stratified by Compliance with Candida Bundle: A Multicenter Retrospective Cohort Study (2016?2023) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Candidemia is a severe systemic infection with a high mortality risk. While β-D-glucan (BDG) serves as a diagnostic biomarker, its prognostic value in candidemia, particularly in association with Candida bundle compliance, remains unclear.
Methods In this retrospective multicenter cohort study, we evaluated 96 patients with candidemia across nine Japanese hospitals between 2016 and 2023. Candida bundle compliance was assessed using five key components: central venous catheter removal within 24 h of diagnosis, appropriate initial antifungal therapy, ophthalmologic examination, follow-up blood cultures until clearance, and antifungal therapy for at least two weeks post-clearance. Analyses stratified patients by serum BDG status (positive/negative) and compliance with the Candida bundle (high: 4?5 points; low: 0?3 points). The primary outcome was 30-day mortality, and the secondary outcome was defined as endophthalmitis incidence.
Results Of 96 eligible patients with candidemia, 70 (72.9%) were BDG-positive and 26 (27.1%) were BDG-negative. The overall 30-day mortality was 17.7%. Among BDG-positive patients, 15 (21.4%) died, while 2 (7.7%) died in BDG-negative cohorts (p?=?0.09). Serum BDG positivity demonstrated a statistically significant association with decreased survival rates in the low bundle adherence group (p?=?0.02), whereas this correlation was not observed among patients in the high-compliance cohort (p?=?0.66). Endophthalmitis occurred in 25.0% of patients, without significant correlation to serum BDG status. C. albicans was associated with a significantly higher incidence of endophthalmitis compared with non-albicans species (45.7% vs. 8.9%).
Conclusions Serum BDG positivity potentially correlates with worse survival in candidemia, particularly in patients with low bundle compliance.

Despite international recommendations for booster vaccinations during adolescence, Japan currently provides only a four-dose primary series during infancy, without subsequent boosters. This immunization gap possibly increases the vulnerability of Japanese athletes to pertussis. Persistent cough can significantly impair athletic performance for weeks to months, posing substantial challenges to professional sports teams. To protect athletes’ health and performance capacity and prevent team-wide outbreaks, it is imperative to consider pertussis booster immunizations in Japan, especially for elite athletes. However, DTaP (diphtheria, tetanus, and acellular pertussis) (TRIBIK?) is the only available vaccine in Japan, which contains higher antigen concentrations than the internationally used Tdap (tetanus, diphtheria, pertussis) vaccines (ADACEL? and BOOSTRIX?): the antigen contents of pertussis toxin, filamentous hemagglutinin, and diphtheria toxin in TRIBIK?, ADACEL?, and BOOSTRIX? are 23.5 ?g/23.5 ?g/?15 ?g, 2.5 ?g/5 ?g/2 ?g, and 8 ?g/8 ?g/2.5 ?g, respectively. These differences result in more severe local adverse effects in vaccinees and would complicate booster strategies in Japan. Aligning Japan’s immunization policies with international practices represents a critical step toward ensuring individual health and public safety in increasingly globalized sports environments. 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= affil-num=1 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= en-keyword=Bordetella pertussis kn-keyword=Bordetella pertussis en-keyword=Vaccination kn-keyword=Vaccination en-keyword=Immunization kn-keyword=Immunization END start-ver=1.4 cd-journal=joma no-vol=122 cd-vols= no-issue=5 article-no= start-page=733 end-page=743 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250715 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Intravenous umbilical cord-derived mesenchymal stromal cell therapy may improve overall survival in Japanese patients with idiopathic pneumonia syndrome after hematopoietic stem cell transplantation: a multicenter, single-arm, phase II trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Idiopathic pneumonia syndrome (IPS) is a serious complication of allogeneic hematopoietic stem cell transplantation (HSCT) and has a poor prognosis. Although IPS is often treated with steroids, the disease can become resistant to or dependent on steroid treatment, and there is no effective cure for patients with refractory or steroid-dependent IPS. This multicenter, open-label, single-arm, phase II clinical trial investigated the efficacy and safety of HLC-001 (allogeneic umbilical cord-derived mesenchymal stromal cells) in patients with progressive steroid-dependent or refractory IPS after HSCT. Seven male patients (all male; mean age: 43.3 years) received HLC-001 and three completed the trial. The survival rate at day 56 (primary endpoint) was 71.4% (5/7 patients; 95% confidence interval: 29.0%?96.3%) and was sustained at day 100, suggesting that HLC-001 was more effective than previously reported treatment. Three of the five patients with ??100 days of follow-up died. Five patients experienced at least one adverse drug reaction, none of which were serious. These findings indicate that HLC-001 was potentially effective and generally well tolerated in Japanese patients with steroid-dependent or refractory IPS after HSCT. Given there is no effective cure for steroid-dependent or refractory IPS, HLC-001 may be a promising treatment option and further clinical evaluation is warranted.

This study aimed to examine whether oral health status and OHRQoL are associated with a change in self-reported depression status among adults in Japan. Methods: We analyzed data from the Japan COVID-19 and Society Internet Survey (JACSIS), conducted in 2022 and 2023. A total of 15,068 participants aged ?20 years without depression at baseline were included. Depression status was identified by self-reported measures between the two survey waves. Logistic regression models estimated odds ratios (ORs) and 95% confidence intervals (CIs) for change in self-reported depression status in relation to OHRQoL and oral health status, adjusting for sociodemographic and behavioral factors. Results: During follow-up, 218 participants (1.45%) reported a change in self-reported depression status. Poorer OHRQoL was significantly associated with a change in self-reported depression status (OR: 1.018; 95% CI: 1.001?1.036; p = 0.039). Additional risk factors included younger age (OR: 0.974; 95% CI: 0.964?0.985), participation in hobbies and cultural activities (OR: 2.224; 95% CI: 1.498?3.302), habitual use of sleeping pills or anxiolytics (current use OR: 3.512; 95% CI: 2.267?5.442), increased loneliness (OR: 1.217; 95% CI: 1.140?1.299), lower life satisfaction (OR: 0.900; 95% CI: 0.836?0.969), and poor self-rated health (OR: 2.921; 95% CI: 1.810?4.715). Conclusions: Impaired OHRQoL was associated with a change in self-reported depression status, potentially through psychosocial mechanisms. These findings suggest that oral health and OHRQoL may be relevant factors to consider in integrated oral and mental health approaches in clinical practice. 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=MaruyamaTakayuki en-aut-sei=Maruyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=KatsubeYuzuki en-aut-sei=Katsube en-aut-mei=Yuzuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TabuchiTakahiro en-aut-sei=Tabuchi en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Division of Dentistry, Medical Development Field, Okayama University kn-affil= affil-num=2 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Dental School, Okayama University kn-affil= affil-num=5 en-affil=Division of Epidemiology, School of Public Health, Tohoku University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=oral health-related quality of life kn-keyword=oral health-related quality of life en-keyword=depression status kn-keyword=depression status en-keyword=cohort study kn-keyword=cohort study END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=5 article-no= start-page=e70094 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Seaweed Extracts Improve Salinity Tolerance in Cereal Crops?A Meta‐Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Seaweeds are considered an essential component of the blue economy. Because seaweed extracts are rich in bioactive compounds that enhance plant stress resilience, exploiting this resource could offer a sustainable solution for crop production. Salinity is a major abiotic challenge that significantly impacts crop yield and food security. Through meta-analysis, we explored whether the exogenous application of seaweed extracts improves the salt tolerance of cereal crops. All the studies chosen for this study utilized aqueous seaweed extracts as foliar sprays. A multi-level meta-analysis with a mixed effects model was performed to determine the effect size. This meta-analysis demonstrated that applying aqueous seaweed extracts enhanced the shoot and root biomass under normal and salinity stress conditions, suggesting that seaweed extract can help improve crop stress tolerance. The seaweeds studied belonged to three classes: Phaeophyceae, Rhodophyta, and Chlorophyta, with extracts from Chlorophyta and Phaeophyceae significantly enhancing biomass production under salinity conditions. Applying aqueous seaweed extracts effectively improved salinity tolerance at both 34.2?100?mM and 101?400?mM NaCl equivalent salinity stress. Moreover, exogenous foliar application of ??25% aqueous seaweed extracts was most effective for improving salinity tolerance in cereals. The impact of seaweed extracts on cereal crop yields has not been extensively reported; therefore, further studies should focus on this aspect. en-copyright= kn-copyright= en-aut-name=NuruzzamanMd. en-aut-sei=Nuruzzaman en-aut-mei=Md. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Tahjib‐Ul‐ArifMd. en-aut-sei=Tahjib‐Ul‐Arif en-aut-mei=Md. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HannanMd.

However, inter-institutional variability in target segmentation and treatment planning can compromise treatment quality. This study aimed to evaluate the segmentation variability and dose distribution quality of SBRT in oligometastatic settings using a multi-institutional dummy run approach.
Methods and materials: Sixty-nine institutions were provided with two anonymized cases of adrenal and spine metastases to delineate targets and organs at risk (OARs) and create intensity-modulated radiotherapy plans following a protocol. Variability was quantified using the Dice similarity coefficient (DSC), Hausdorff distance, and mean distance to agreement. Plan qualities were assessed using the Paddick conformity index, modified gradient index, and a new three-dimensional conformity?gradient index (3D-CGI). Knowledge-based planning (KBP) was applied to explore potential improvements in OAR sparing.
Results: All submitted plans met protocol dose constraints. However, substantial segmentation variability was observed, particularly for the spine case. Among 136 plans, 79% demonstrated acceptable conformity and dose gradients, with 3D-CGI < 6 correlating with favorable distributions. Mean DSC was 0.93 for the clinical target volume and 0.76 for the cauda equina, which showed the highest variability. KBP reduced OAR doses for the adrenal case but showed limited impact for the spine case.
Conclusions: Although dose constraints were achieved, segmentation variability remained substantial, particularly for the cauda equina in the spine case. These findings emphasize inter-institutional differences and the need for standardization and tools to improve SBRT consistency. en-copyright= kn-copyright= en-aut-name=HirashimaHideaki en-aut-sei=Hirashima en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuoYukinori en-aut-sei=Matsuo en-aut-mei=Yukinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshikuraSatoshi en-aut-sei=Ishikura en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakamuraMitsuhiro en-aut-sei=Nakamura en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishibuchiIkuno en-aut-sei=Nishibuchi en-aut-mei=Ikuno kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KawaharaDaisuke en-aut-sei=Kawahara en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShimadaYoshihisa en-aut-sei=Shimada en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakaharaYoshiro en-aut-sei=Nakahara en-aut-mei=Yoshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NishioTeiji en-aut-sei=Nishio en-aut-mei=Teiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ShikamaNaoto en-aut-sei=Shikama en-aut-mei=Naoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=WatanabeShun-ichi en-aut-sei=Watanabe en-aut-mei=Shun-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OkamotoIsamu en-aut-sei=Okamoto en-aut-mei=Isamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=IshibaToshiyuki en-aut-sei=Ishiba en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=HaraFumikata en-aut-sei=Hara en-aut-mei=Fumikata kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=ShienTadahiko en-aut-sei=Shien en-aut-mei=Tadahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=MizowakiTakashi en-aut-sei=Mizowaki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Radiation Oncology and Image-Applied Therapy, Graduate School of Medicine, Kyoto University kn-affil= affil-num=2 en-affil=Department of Radiation Oncology, Kindai University Faculty of Medicine kn-affil= affil-num=3 en-affil=Department of Radiation Oncology, St. Luke’s International Hospital, St. Luke’s International University kn-affil= affil-num=4 en-affil=Department of Advanced Medical Physics, Graduate School of Medicine, Kyoto University kn-affil= affil-num=5 en-affil=Department of Radiation Oncology, Graduate School of Biomedical Health Sciences, Hiroshima University kn-affil= affil-num=6 en-affil=Department of Radiation Oncology, Graduate School of Biomedical Health Sciences, Hiroshima University kn-affil= affil-num=7 en-affil=Department of Surgery, Tokyo Medical University kn-affil= affil-num=8 en-affil=Department of Respiratory Medicine, Kitasato University Hospital kn-affil= affil-num=9 en-affil=Medical Physics Laboratory, Division of Health Science, Graduate School of Medicine, The University of Osaka kn-affil= affil-num=10 en-affil=Department of Radiation Oncology, Juntendo University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Thoracic Surgery, National Cancer Center Hospital kn-affil= affil-num=12 en-affil=Department of Respiratory Medicine, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=13 en-affil=Department of Breast Surgery, Institute of Science Tokyo kn-affil= affil-num=14 en-affil=Department of Breast Oncology, Aichi Cancer Center Hospital kn-affil= affil-num=15 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=16 en-affil=Department of Radiation Oncology and Image-Applied Therapy, Graduate School of Medicine, Kyoto University kn-affil= en-keyword=Oligometastatic disease kn-keyword=Oligometastatic disease en-keyword=Dummy run kn-keyword=Dummy run en-keyword=Segmentation variability kn-keyword=Segmentation variability en-keyword=Dose distribution accuracy kn-keyword=Dose distribution accuracy END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue= article-no= start-page=20250037 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=Reliability and Validity of the Japanese Perme ICU Mobility Score: An Initial Psychometric Evaluation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives : The Perme ICU Mobility Score is widely used to assess functional status, but no version of this assessment tool has been validated for use in Japan. This study aimed to translate the Perme Score into Japanese and evaluate its reliability and validity.
Methods : Following forward?backward translation, the Japanese Perme Score was tested at ICU discharge. Inter-rater reliability was examined using weighted kappa coefficient. Construct validity was assessed through correlations with the Medical Research Council Sum Score (MRC-SS), Functional Status Score for the ICU (FSS-ICU), and ICU Mobility Scale (IMS). Predictive validity for activities of daily living (ADL) independence (Barthel Index ??85) and discharge destination was evaluated using Receiver operating characteristic (ROC) analysis. Floor and ceiling effects were also analyzed.
Results : In 69 patients, the Japanese Perme Score showed high inter-rater reliability (κ=0.83). It showed moderate correlation with FSS-ICU (rho=0.61) and IMS (rho=0.73), and it showed weak correlation with MRC-SS (rho=0.36). Predictive validity for ADL independence and home discharge yielded AUCs of 0.76 and 0.73, respectively. A ceiling effect was noted in 10% of cases, with no floor effect.
Conclusions: The Japanese Perme Score is a reliable, valid instrument for evaluating physical function at ICU discharge. en-copyright= kn-copyright= en-aut-name=KatayamaSho en-aut-sei=Katayama en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkedaTomohiro en-aut-sei=Ikeda en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakanishiNobuto en-aut-sei=Nakanishi en-aut-mei=Nobuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatsukawaHajime en-aut-sei=Katsukawa en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NawaRicardo Kenji en-aut-sei=Nawa en-aut-mei=Ricardo Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=PermeChristiane en-aut-sei=Perme en-aut-mei=Christiane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HamadaMasanori en-aut-sei=Hamada en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SatoIkumi en-aut-sei=Sato en-aut-mei=Ikumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HirohataSatoshi en-aut-sei=Hirohata en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Disaster and Emergency Medicine, Graduate School of Medicine, Kobe University kn-affil= affil-num=4 en-affil=Department of Scientific Research, Japanese Society for Early Mobilization kn-affil= affil-num=5 en-affil=Department of Critical Care Medicine, Hospital Israelita Albert Einstein kn-affil= affil-num=6 en-affil=Department of Rehabilitation Services, Houston Methodist Hospital 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 Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Academic Field of Health Science, Okayama University kn-affil= affil-num=10 en-affil=Academic Field of Health Science, Okayama University kn-affil= en-keyword=critical illness kn-keyword=critical illness en-keyword=intensive care unit kn-keyword=intensive care unit en-keyword=outcome assessment kn-keyword=outcome assessment en-keyword=physical function kn-keyword=physical function en-keyword=rehabilitation kn-keyword=rehabilitation END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=100511 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genetic variability in Neisseria meningitidis strains isolated in a Japanese hospital en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Neisseria meningitidis is a significant pathogen causing invasive meningococcal disease, posing clinical and public health concerns worldwide. This study aimed to investigate the genetic characteristics of N. meningitidis clinical isolates at Okayama University Hospital in Japan.
Methods: Between 2018 and 2023, five clinical strains were isolated, of which three were subjected to the antimicrobial susceptibility testing and whole genetic analysis using MiSeq platform (Illumina, San Diego, CA, USA).
Results: One non-groupable isolate, belonging to sequence types (STs)-11026 (ST-32 complex), exhibited non-susceptibility to penicillin G, with a five-mutation pattern (F504L, A510V, I515V, H541N, and I566V) in the penA amino acid sequence and additional mutations (XXXIV and N513Y) characteristic of a mosaic penA gene. The other two isolates, ST-1655 (ST-23 complex) with serogroup Y and ST-2057 with serogroup B, were susceptible to penicillin G, neither of which contained the five-mutation pattern. Levofloxacin resistance was observed in two isolates carrying the T91I mutation in the gyrA protein.
Conclusion: Our findings suggest the presence of antimicrobial-resistant N. meningitidis in Japan, underscoring the necessity for continuous local surveillance. Additional research is crucial for clarifying the ongoing spread of resistance mechanisms and for establishing effective countermeasures to reduce the clinical burden of invasive meningococcal disease. en-copyright= kn-copyright= en-aut-name=GotohKazuyoshi en-aut-sei=Gotoh en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=TsujiShuma en-aut-sei=Tsuji en-aut-mei=Shuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IioKoji en-aut-sei=Iio en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsushitaOsamu en-aut-sei=Matsushita en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=2 en-affil=Department of Bacteriology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Bacteriology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Antimicrobial resistance kn-keyword=Antimicrobial resistance en-keyword=Invasive meningococcal disease kn-keyword=Invasive meningococcal disease en-keyword=Drug-resistant gene kn-keyword=Drug-resistant gene en-keyword=Genome sequence kn-keyword=Genome sequence END start-ver=1.4 cd-journal=joma no-vol=69 cd-vols= no-issue=12 article-no= start-page=e00740-25 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genomic portrayal of emerging carbapenem-resistant El Tor variant Vibrio cholerae O1 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The escalating prevalence of carbapenem-resistant (CR) enteric pathogens elicits significant challenges to public health management and effective antimicrobial therapy. While carbapenem resistance is rare in Vibrio cholerae O1 (VC), the recent emergence of CR strains reveals a concerning shift in their antimicrobial resistance (AMR) landscape. This study aims to characterize the resistance mechanisms in newly identified El Tor CRVC isolated from cholera patients in Gujarat, India during 2019. Fifty VC isolates were screened for major virulence-associated genes along with the determination of their antibiotic resistance profiles using Kirby-Bauer disk diffusion and MIC assays. Whole-genome sequencing (WGS) was employed to investigate the underlying mechanisms of CR. All the isolates exhibited hypervirulent Haitian alleles of major virulence genes and AMR profiles of typical multidrug resistance (MDR). Strikingly, 12% (6/50) of them were resistant to carbapenems and other antibiotics. Molecular analysis revealed that these CR isolates were clonally related and harbored a 142 kbp IncA/C type conjugative mega-plasmid with several AMR encoding genes, including blaNDM-1, that can be easily transferred to other bacterial species and confer donor AMR patterns. The plasmid’s competence for horizontal gene transfer presents a significant risk of dissemination to other enteric pathogens and thereby may complicate the treatment. This finding emphasizes the urgent need for enhanced genomic surveillance and robust antimicrobial stewardship programs aimed at curbing the spread of CRVC strains and mitigating their impact on cholera treatment and containment strategies. en-copyright= kn-copyright= en-aut-name=ShawSreeja en-aut-sei=Shaw en-aut-mei=Sreeja kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PragasamAgila Kumari en-aut-sei=Pragasam en-aut-mei=Agila Kumari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ChowdhuryGoutam en-aut-sei=Chowdhury en-aut-mei=Goutam kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SamantaProsenjit en-aut-sei=Samanta en-aut-mei=Prosenjit kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=RoyDeboleena en-aut-sei=Roy en-aut-mei=Deboleena kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GhoshDebjani en-aut-sei=Ghosh en-aut-mei=Debjani kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=RamamurthyThandavarayan en-aut-sei=Ramamurthy en-aut-mei=Thandavarayan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KariaJigna en-aut-sei=Karia en-aut-mei=Jigna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NinamaGovind en-aut-sei=Ninama en-aut-mei=Govind kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=AkedaYukihiro en-aut-sei=Akeda en-aut-mei=Yukihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KoleyHemanta en-aut-sei=Koley en-aut-mei=Hemanta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MukhopadhyayAsish Kumar en-aut-sei=Mukhopadhyay en-aut-mei=Asish Kumar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=ICMR-National Institute for Research in Bacterial Infections kn-affil= affil-num=2 en-affil=V.

Generally, measurement methods for characterizing the material are based on the use of a vector network analyzer (VNA), which is large and not easy for on-site measurement, especially in high-frequency range such as millimeter wave (mmWave). In addition, some measurement methods require the destruction of samples, which is not suitable for nondestructive inspection. In this work, a small distance increment (SDI) method is proposed to nondestructively measure the complex permittivity of a material. In SDI, the transmitter and receiver are formed as a monostatic radar, which is facing toward the material under test (MUT). During the measurement, the distance between the radar and the MUT changes with small increments, and the signals are recorded at each position. A mathematical model is formulated to depict the relationship among the complex permittivity, distance increment, and measured signals. By fitting the model, the complex permittivity of MUT is estimated. To implement and evaluate the proposed SDI method, a commercial off-the-shelf (COTS) mmWave radar is utilized, and the measurement system is developed. Then, the evaluation was carried out on the acrylic plate. With the proposed method, the estimated complex permittivity of the acrylic plate shows good agreement with the literature values, demonstrating the efficacy of the SDI method for characterizing the complex permittivity of the material. en-copyright= kn-copyright= en-aut-name=SongHang en-aut-sei=Song en-aut-mei=Hang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimHyun Joon en-aut-sei=Kim en-aut-mei=Hyun Joon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WanMingxia en-aut-sei=Wan en-aut-mei=Mingxia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WeiBo en-aut-sei=Wei en-aut-mei=Bo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KikkawaTakamaro en-aut-sei=Kikkawa en-aut-mei=Takamaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakadaJun-Ichi en-aut-sei=Takada en-aut-mei=Jun-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Research Institute for Semiconductor Engineering, Hiroshima University kn-affil= affil-num=2 en-affil=Department of Transdisciplinary Science and Engineering, Institute of Science Tokyo kn-affil= affil-num=3 en-affil=Department of Transdisciplinary Science and Engineering, Institute of Science Tokyo kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Research Institute for Semiconductor Engineering, Hiroshima University kn-affil= affil-num=6 en-affil=Department of Transdisciplinary Science and Engineering, Institute of Science Tokyo kn-affil= en-keyword=Complex permittivity measurement kn-keyword=Complex permittivity measurement en-keyword=material characterization kn-keyword=material characterization en-keyword=millimeter wave (mmWave) radar kn-keyword=millimeter wave (mmWave) radar en-keyword=nondestructive inspection kn-keyword=nondestructive inspection en-keyword=small distance increment (SDI) method kn-keyword=small distance increment (SDI) method END start-ver=1.4 cd-journal=joma no-vol=134 cd-vols= no-issue=1 article-no= start-page=1 end-page=4 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structural and spectroscopic characterization of keatite (SiO2) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Keatite, a polymorph of silica rare in nature, was synthesized by hydrothermal treatment of silicon and water at 100 MPa and 600 °C. The crystal structure of keatite at 24 °C was refined by the Rietveld method using synchrotron X-ray diffraction data. The obtained structure is consistent with the results of previous studies in which some constraints were imposed during refinements. The 29Si MAS NMR spectrum of keatite shows two peaks at ?113.9 and ?114.3 ppm, which can be assigned to Si at the Si1 and Si2 sites, respectively. The Raman spectrum of keatite shows a prominent peak at 473 cm?1, which is attributable to the Si?O?Si bending mode of the 5-membered ring. These spectra, reported for the first time, are expected to be valuable for the identification of keatite in synthetic and natural samples. en-copyright= kn-copyright= en-aut-name=KanzakiMasami en-aut-sei=Kanzaki en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=XueXianyu en-aut-sei=Xue en-aut-mei=Xianyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=Institute for Planetary Materials, Okayama University kn-affil= en-keyword=SiO2 kn-keyword=SiO2 en-keyword=Keatite kn-keyword=Keatite en-keyword=Crystal structure kn-keyword=Crystal structure en-keyword=Raman spectroscopy kn-keyword=Raman spectroscopy en-keyword=NMR spectroscopy kn-keyword=NMR spectroscopy END start-ver=1.4 cd-journal=joma no-vol=137 cd-vols= no-issue=3 article-no= start-page=126 end-page=131 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A survey of college students' knowledge and awareness of hereditary cancer kn-title=遺伝性腫瘍に関する大学生の知識と意識調査 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　Genomic information plays a critical role in the diagnosis and treatment of various diseases, as well as in the management of asymptomatic individuals. This study assessed the knowledge and understanding of genetics and hereditary cancer among college students who received cancer education in Japan. The study subjects were students from fields such as education, medicine, law, and economics who participated during the period from February to December 2023. The students attended in-person lectures on genomic medicine, and they were then asked to complete an anonymous survey via Google Forms. Over 90％ of the participants reported understanding the content of the lectures, and >80％ indicated that they found the lecture's content understandable at a junior high school level. Over 60％ felt that the appropriate time to begin such education would be in late elementary or junior high school. These results indicate a high level of acceptance of hereditary cancer education among young people. However, challenges remain in their understanding of the roles of genetic factors in cancer development and the mechanisms by which inheritance and phenotype are manifested. The relevant educational programs need to be further refined and strengthened. en-copyright= kn-copyright= en-aut-name=SogawaReimi en-aut-sei=Sogawa en-aut-mei=Reimi kn-aut-name=十川麗美 kn-aut-sei=十川 kn-aut-mei=麗美 aut-affil-num=1 ORCID= en-aut-name=WadaTakahito en-aut-sei=Wada en-aut-mei=Takahito kn-aut-name=和田敬仁 kn-aut-sei=和田 kn-aut-mei=敬仁 aut-affil-num=2 ORCID= en-aut-name=HirasawaAkira en-aut-sei=Hirasawa en-aut-mei=Akira kn-aut-name=平沢晃 kn-aut-sei=平沢 kn-aut-mei=晃 aut-affil-num=3 ORCID= en-aut-name=KumamotoKensuke en-aut-sei=Kumamoto en-aut-mei=Kensuke kn-aut-name=隈元謙介 kn-aut-sei=隈元 kn-aut-mei=謙介 aut-affil-num=4 ORCID= en-aut-name=OhmoriIori en-aut-sei=Ohmori en-aut-mei=Iori kn-aut-name=大守伊織 kn-aut-sei=大守 kn-aut-mei=伊織 aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Clinical Genetics and Genomic Medicine, Kagawa University Hospital kn-affil=香川大学医学部附属病院　臨床遺伝ゲノム診療科 affil-num=2 en-affil=Department of Genomic Medicine, Kyoto University Graduate School of Medicine kn-affil=京都大学大学院医学研究科　ゲノム医療学 affil-num=3 en-affil=Department of Clinical Genomic Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学学術研究院医歯薬学域　臨床遺伝医療学 affil-num=4 en-affil=Department of Clinical Genetics and Genomic Medicine, Kagawa University Hospital kn-affil=香川大学医学部附属病院　臨床遺伝ゲノム診療科 affil-num=5 en-affil=Special Needs Education, Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域　特別支援教育 en-keyword=遺伝性腫瘍 (hereditary cancer) kn-keyword=遺伝性腫瘍 (hereditary cancer) en-keyword=ゲノム教育 (genome education) kn-keyword=ゲノム教育 (genome education) en-keyword=市民教育 (public education) kn-keyword=市民教育 (public education) en-keyword=学校教育 (school education) kn-keyword=学校教育 (school education) END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=3 article-no= start-page=168 end-page=178 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=Polyphyletic domestication and inter-lineage hybridization magnified genetic diversity of cultivated melon, Cucumis melo L. en-subtitle= kn-subtitle= en-abstract= kn-abstract=Melon accessions with diverse geographical origins were classified into large and small seed-types by length of seed at the boundary of 9?mm, and into five populations based on polymorphisms in the nuclear genome. They were further divided into three maternal lineages, Ia, Ib, and Ic, by polymorphisms in the chloroplast genome. By combining these three classifications, the Europe/US subsp. melo and the East Asian subsp. agrestis were characterized as [large seed, Ib, PopA1 or A2] and [small seed, Ia, PopB1 or B2], respectively, indicating nearly perfect divergence. In South Asia, in addition to the Europe/US and East Asian types, recombinant types between the two types were detected and accounted for 34.8% of South Asian melon. The finding of such an intermixed structure of genetic variation supported the Indian origin of Ia and Ib types. As to Momordica popular in South Asia, seed length was intermediate between the large and small seed-types, and chloroplast type was a mixture of Ia and Ib, suggesting its origin from the recombinant type. In Africa, three lineages of melon were distributed allopatrically and showed distinct divergence. Subsp. agrestis of the Ic type proved to be endemic to Africa, indicating its African origin. en-copyright= kn-copyright= en-aut-name=TanakaKatsunori en-aut-sei=Tanaka en-aut-mei=Katsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShigitaGentaro en-aut-sei=Shigita en-aut-mei=Gentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DungTran Phuong en-aut-sei=Dung en-aut-mei=Tran Phuong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NhiPhan Thi Phuong en-aut-sei=Nhi en-aut-mei=Phan Thi Phuong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahashiMami en-aut-sei=Takahashi en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MondenYuki en-aut-sei=Monden en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishidaHidetaka en-aut-sei=Nishida en-aut-mei=Hidetaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IshikawaRyuji en-aut-sei=Ishikawa en-aut-mei=Ryuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KatoKenji en-aut-sei=Kato en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Faculty of Agriculture and Life Science, Hirosaki 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=University of Agriculture and Forestry, Hue University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University 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=Faculty of Agriculture and Life Science, Hirosaki University kn-affil= affil-num=9 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=chloroplast genome kn-keyword=chloroplast genome en-keyword=Cucumis melo kn-keyword=Cucumis melo en-keyword=domestication kn-keyword=domestication en-keyword=genetic diversity kn-keyword=genetic diversity en-keyword=melon kn-keyword=melon en-keyword=molecular polymorphism kn-keyword=molecular polymorphism en-keyword=seed size kn-keyword=seed size END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=8 article-no= start-page=938 end-page=943 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=Clinical outcomes of Japanese patients treated with out-of-specification tisagenlecleucel in a phase 3b trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The final manufactured tisagenlecleucel product should meet the commercial product release specifications to ensure the quality in terms of safety, purity, identity, and potency. However, it may occasionally fail to meet these specifications due to the nature of patient-derived cells with variable properties as starting material and the complex manufacturing process. The final product that does not meet at least one of the commercial release specifications is referred to as “out-of-specification” (OOS). However, the benefit-risk profile of OOS tisagenlecleucel has not yet been fully elucidated.
Aims: To evaluate the safety and efficacy of OOS tisagenlecleucel in Japanese patients with relapsed or refractory (r/r) diffuse large B-cell lymphoma (DLBCL) and B-cell acute lymphoblastic leukemia (B-ALL).
Methods: This is a single-arm, open-label, multicenter phase 3b study (NCT04094311). Patients consistent with label indication were enrolled and followed-up for 3 months.
Results: Of the 29 patients enrolled between December 2019 and May 2022 across 13 qualified sites in Japan, 28 received tisagenlecleucel, and of these, 23 had r/r DLBCL and 5 had r/r B-ALL. The primary reasons for OOS were low cell viability (15 of 24 batches) and low dose (8 of 23 batches) tisagenlecleucel in the r/r DLBCL group, and high dose (4 of 5 batches) in the r/r B-ALL group. In patients with r/r DLBCL, the grade 3 or 4 cytokine release syndrome and immune effector cell-associated neurotoxicity syndrome occurred in 3 and 1 patients, respectively. Response assessments were performed for 15 of 23 patients with r/r DLBCL: 6 achieved a complete response, and 1 achieved a partial response as the best response within 3 months.
Conclusions: Despite the limited patient sample size, our findings affirm that the infusion of OOS tisagenlecleucel is a viable option, with no observed increase in toxicity and outcomes comparable to those of in-specification products in clinical and real-world studies. en-copyright= kn-copyright= en-aut-name=KatoKoji en-aut-sei=Kato en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatoJun en-aut-sei=Kato en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GotoHideki en-aut-sei=Goto en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KobayashiTakeshi en-aut-sei=Kobayashi en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahashiYoshiyuki en-aut-sei=Takahashi en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakaidaEmiko en-aut-sei=Sakaida en-aut-mei=Emiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HiramatsuHidefumi en-aut-sei=Hiramatsu en-aut-mei=Hidefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamamotoMasahide en-aut-sei=Yamamoto en-aut-mei=Masahide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YoshiharaSatoshi en-aut-sei=Yoshihara en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AndoJun en-aut-sei=Ando en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KohKatsuyoshi en-aut-sei=Koh en-aut-mei=Katsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=FukushimaKentaro en-aut-sei=Fukushima en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=IwamotoFumiko en-aut-sei=Iwamoto en-aut-mei=Fumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=TiwariRanjan en-aut-sei=Tiwari en-aut-mei=Ranjan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Hematology, Oncology, and Cardiovascular Medicine, Kyushu University Hospital kn-affil= affil-num=2 en-affil=Division of Hematology, Department of Medicine, Keio University School of Medicine kn-affil= affil-num=3 en-affil=Division of Laboratory and Transfusion Medicine, Hokkaido University Hospital kn-affil= affil-num=4 en-affil=Hematology Division, Tokyo Metropolitan Cancer and Infectious Diseases Center Komagome Hospital kn-affil= affil-num=5 en-affil=Department of Pediatrics, Nagoya University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Hematology, Chiba University Hospital kn-affil= affil-num=7 en-affil=Department of Pediatrics, Graduate School of Medicine, Kyoto University kn-affil= affil-num=8 en-affil=Department of Hematology, Institute of Science Tokyo Hospital kn-affil= affil-num=9 en-affil=Department of Hematology, Hyogo Medical University Hospital kn-affil= affil-num=10 en-affil=Department of Cell Therapy and Transfusion Medicine, Juntendo University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Hematology/Oncology, Saitama Children’s Medical Center kn-affil= affil-num=12 en-affil=Department of Hematology and Oncology, Osaka University Graduate School of Medicine kn-affil= affil-num=13 en-affil=Medical Affairs, Novartis Pharma K.K. kn-affil= affil-num=14 en-affil=Development Advance Quantitative Sciences, Novartis Healthcare Private Limited kn-affil= affil-num=15 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= en-keyword=CAR-T kn-keyword=CAR-T en-keyword=DLBCL kn-keyword=DLBCL en-keyword=Out-of-specification kn-keyword=Out-of-specification en-keyword=Safety kn-keyword=Safety en-keyword=Tisagenlecleucel kn-keyword=Tisagenlecleucel END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=RP99936 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250811 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Redistribution of fragmented mitochondria ensures symmetric organelle partitioning and faithful chromosome segregation in mitotic mouse zygotes en-subtitle= kn-subtitle= en-abstract= kn-abstract=In cleavage-stage embryos, preexisting organelles partition evenly into daughter blastomeres without signi?cant cell growth after symmetric cell division. The presence of mitochondrial DNA within mitochondria and its restricted replication during preimplantation development makes their inheritance particularly important. While chromosomes are precisely segregated by the mitotic spindle, the mechanisms controlling mitochondrial partitioning remain poorly understood. In this study, we investigate the mechanism by which Dynamin-related protein 1 (Drp1) controls the mitochondrial redistribution and partitioning during embryonic cleavage. Depletion of Drp1 in mouse zygotes causes marked mitochondrial aggregation, and the majority of embryos arrest at the 2 cell stage. Clumped mitochondria are located in the center of mitotic Drp1-depleted zygotes with less uniform distribution, thereby preventing their symmetric partitioning. Asymmetric mitochondrial inheritance is accompanied by functionally inequivalent blastomeres with biased ATP and endoplasmic reticulum Ca2+ levels. We also find that marked mitochondrial centration in Drp1-depleted zygotes prevents the assembly of parental chromosomes, resulting in chromosome segregation defects and binucleation. Thus, mitochondrial fragmentation mediated by Drp1 ensures proper organelle positioning and partitioning into functional daughters during the first embryonic cleavage. en-copyright= kn-copyright= en-aut-name=GekkoHaruna en-aut-sei=Gekko en-aut-mei=Haruna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NomuraRuri en-aut-sei=Nomura en-aut-mei=Ruri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KuzuharaDaiki en-aut-sei=Kuzuhara en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KaneyasuMasato en-aut-sei=Kaneyasu en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KosekiGenpei en-aut-sei=Koseki en-aut-mei=Genpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AdhikariDeepak en-aut-sei=Adhikari en-aut-mei=Deepak kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MioYasuyuki en-aut-sei=Mio en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=CarrollJohn en-aut-sei=Carroll en-aut-mei=John kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KonoTomohiro en-aut-sei=Kono en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FunahashiHiroaki en-aut-sei=Funahashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=WakaiTakuya en-aut-sei=Wakai en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Animal Science, Graduate School of Environment and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Animal Science, Graduate School of Environment and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Reproductive Centre, Mio Fertility Clinic kn-affil= affil-num=4 en-affil=Department of Animal Science, Graduate School of Environment and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Animal Science, Graduate School of Environment and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Development and Stem Cell Program and Department of Anatomy and Developmental Biology, Monash Biomedicine Discovery Institute, Monash University kn-affil= affil-num=7 en-affil=Reproductive Centre, Mio Fertility Clinic kn-affil= affil-num=8 en-affil=Development and Stem Cell Program and Department of Anatomy and Developmental Biology, Monash Biomedicine Discovery Institute, Monash University kn-affil= affil-num=9 en-affil=Department of Bioscience, Tokyo University of Agriculture kn-affil= affil-num=10 en-affil=Department of Animal Science, Graduate School of Environment and Life Science, Okayama University kn-affil= affil-num=11 en-affil=Department of Animal Science, Graduate School of Environment and Life Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251117 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genomic Profiling of Pediatric Solid Tumors With a Dual DNA/RNA Panel: JCCG-TOP2 Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=To develop an optimized genomic medicine platform for pediatric cancers, a nationwide cancer genome profiling project was conducted from January 2022 to February 2023 in collaboration with the Japan Children's Cancer Group. This prospective observational study analyzed matched blood and FFPE tumor samples from patients aged 0?29?years with solid tumors. Genomic analysis used the TOP2 hybrid capture?enrichment system, targeting 737 and 455 genes in the DNA and RNA panels, along with allele-specific genome copy number alterations. A total of 210 patients from 50 institutions were enrolled across Japan (median age, 8?years; range, 0?25). Of these, 154 (77%) were enrolled at diagnosis or during/after initial treatment and 56 (27%) at disease progression or relapse. The TOP2 findings had great benefits in clarifying the diagnosis of pediatric solid tumors. Among the 204 patients with genomic results, 147 (72%) had potentially actionable findings, including diagnostic, prognostic, and therapeutic findings in 111 (54%), 61 (30%), and 64 (31%), respectively. Oncogenic fusions were noted in 45 (23%) patients. A copy number alteration was identified in at least one genomic region in 170 (83%) patients. Two patients exhibited a high tumor mutation burden. Seventeen (8%) patients harbored a germline pathogenic/likely pathogenic variant in cancer-predisposing genes. This study highlighted the feasibility of implementing a nationwide precision medicine platform and the clinical utility of the TOP2 system for pediatric cancers. The results support the integration of genomic data into the standard clinical care of pediatric patients with cancer, both at diagnosis and at relapse. en-copyright= kn-copyright=

(Matricaria chamomilla) Induces Cytochrome P450 Expression Through Increased BMAL1 Protein Expression in Liver Nuclei en-subtitle= kn-subtitle= en-abstract= kn-abstract=German chamomile (Matricaria chamomilla) is a medicinal herb that promotes improved digestion and reduces insomnia. Although it is widely used worldwide, the mechanism of induction of drug-metabolizing enzymes is unknown. We found that German chamomile extracts induced cytochrome P450 expression at the transcriptional stage. Cyp3a11 expression is decreased at night in wild-type mice, but German chamomile extract induced nocturnal Cyp3a11 and Cyp1a2 expression. German chamomile extract increased the nuclear protein expression of the clock gene BMAL1, which drives and abolishes the rhythm of Cyp3a11 expression. By contrast, German chamomile extract did not significantly alter clock gene expression in the suprachiasmatic nucleus (SCN). Similarly, it did not affect the mRNA expression of the clock genes in the kidneys. Because it did not induce the mRNA expression of ATP-binding cassette (ABC) transporters (Abcb1a, Abcc2, Abcc4, and Abcg2) in the kidney, German chamomile extract had no effect on the transcription of pharmacokinetics-related molecules other than CYPs. German chamomile extract promoted liver-selective nuclear transfer rhythm changes in clock genes and induced the expression of CYPs. This study may help to explain the mechanism of drug interactions associated with chronic German chamomile extract consumption. en-copyright= kn-copyright= en-aut-name=IkedaMoka en-aut-sei=Ikeda en-aut-mei=Moka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsurudomeYuya en-aut-sei=Tsurudome en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EnrinMai en-aut-sei=Enrin en-aut-mei=Mai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WadaYukiyo en-aut-sei=Wada en-aut-mei=Yukiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HoriguchiMichiko en-aut-sei=Horiguchi en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UshijimaKentaro en-aut-sei=Ushijima en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Division of Pharmaceutics, Faculty of Pharmaceutical Sciences, Sanyo-Onoda City University kn-affil= affil-num=2 en-affil=Division of Pharmaceutics, Faculty of Pharmaceutical Sciences, Sanyo-Onoda City University kn-affil= affil-num=3 en-affil=Division of Pharmaceutics, Faculty of Pharmaceutical Sciences, Sanyo-Onoda City University kn-affil= affil-num=4 en-affil=Division of Pharmaceutics, Faculty of Pharmaceutical Sciences, Sanyo-Onoda City University kn-affil= affil-num=5 en-affil=Department of Regenerative and Therapeutic Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Division of Pharmaceutics, Faculty of Pharmaceutical Sciences, Sanyo-Onoda City University kn-affil= en-keyword=Circadian clock kn-keyword=Circadian clock en-keyword=German chamomile kn-keyword=German chamomile en-keyword=Xenobiotic transporter kn-keyword=Xenobiotic transporter en-keyword=Metabolic enzyme kn-keyword=Metabolic enzyme en-keyword=Clock gene kn-keyword=Clock gene END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=22 article-no= start-page=gkaf1322 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251126 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=eIF2D promotes 40S ribosomal subunit recycling during intrinsic ribosome destabilization en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although eukaryotic initiation factor 2D (eIF2D) is implicated in translation initiation, reinitiation, and ribosome recycling, its precise role remains unclear. Here, we show that eIF2D promotes 40S ribosome recycling during intrinsic ribosome destabilization (IRD), a process in which ribosomes stochastically destabilize while translating proteins with consecutive acidic amino acids at their NH2-terminus. Unrecycled 40S ribosomes accumulate in eIF2D-deficient cells, leading to 80S ribosome stalling. Selective translation complex profiling (TCP-seq) reveals that eIF2D preferentially associates with IRD-prone regions. The winged helix domain, unique to eIF2D but absent in MCTS1?DENR, enhances its binding to 40S subunits, but likely clashes with ABCE1 during stop-codon-associated recycling. Loss of eIF2D reduces the expression of IRD-inducing proteins, including splicing factors. Together, these findings define a previously unappreciated role for eIF2D in 40S recycling and clarify its mechanistic divergence from the MCTS1?DENR complex. en-copyright= kn-copyright=

Anatomical Textbooks, Atlases, and Journals: A Consensus Response From Authors and Editors en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, consent to use donor bodies for medical education and research is obtained from the body donors and their families before the donation. Recently, the International Federation of Associations of Anatomists (IFAA) published guidelines that could restrict the appearance of cadaveric images in commercial anatomical resources such as textbooks and other educational products. These guidelines state that the donor must expressly consent to using such images for this purpose. Cadaveric photos and drawings made from dissections of cadavers have been used in anatomy textbooks and atlases for hundreds of years. They are invaluable for anatomy students and clinical/surgical practitioners. The IFAA guidelines should not restrict the use of those older books; to do so would infringe the rights of those seeking knowledge from these resources. As the images in such textbooks and atlases are anonymized and are used for teaching and research, and the donors and their families are informed about this before the donation, we believe no additional consent is needed. It is impossible to separate educational from “commercial” usage entirely in any situation, e.g., publications from publishers and the use of cadavers in medical schools. Therefore, our best efforts to avoid unethical use of cadaveric images by following traditional consent processes are still needed so that more people will reap the benefits from them. As senior textbook/atlas authors/editors from over 10 countries, we believe that using cadaveric images in anatomy textbooks is appropriate, and no additional consent should be necessary. Such usage falls within the good faith of professionals using these invaluable gifts. 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=KimHee‐Jin en-aut-sei=Kim en-aut-mei=Hee‐Jin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AkitaKeiichi en-aut-sei=Akita en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LoganBari M. en-aut-sei=Logan en-aut-mei=Bari M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HutchingsRalph T. en-aut-sei=Hutchings en-aut-mei=Ralph T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OttoneNicol?s en-aut-sei=Ottone en-aut-mei=Nicol?s kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NonakaYoichi en-aut-sei=Nonaka en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AnandMahindra en-aut-sei=Anand en-aut-mei=Mahindra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=BurnsDanny en-aut-sei=Burns en-aut-mei=Danny kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SinghVishram en-aut-sei=Singh en-aut-mei=Vishram kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=Peris‐CeldaMaria en-aut-sei=Peris‐Celda en-aut-mei=Maria kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=Martinez‐SorianoFrancisco en-aut-sei=Martinez‐Soriano en-aut-mei=Francisco kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=ApaydinNihal en-aut-sei=Apaydin en-aut-mei=Nihal kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=HannaAmgad en-aut-sei=Hanna en-aut-mei=Amgad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=YoshiokaNobutaka en-aut-sei=Yoshioka en-aut-mei=Nobutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=Fernandez‐MirandaJuan en-aut-sei=Fernandez‐Miranda en-aut-mei=Juan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=HurMi‐Sun en-aut-sei=Hur en-aut-mei=Mi‐Sun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=ShojaMohammadali M. en-aut-sei=Shoja en-aut-mei=Mohammadali M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= en-aut-name=SaremiFarhood en-aut-sei=Saremi en-aut-mei=Farhood kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=19 ORCID= en-aut-name=ReinaFrancisco en-aut-sei=Reina en-aut-mei=Francisco kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=20 ORCID= en-aut-name=TabiraYoko en-aut-sei=Tabira en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=21 ORCID= en-aut-name=CarreraAnna en-aut-sei=Carrera en-aut-mei=Anna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=22 ORCID= en-aut-name=SprattJonathan D. en-aut-sei=Spratt en-aut-mei=Jonathan D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=23 ORCID= en-aut-name=HoS.

Multiple factors, including genetic factors, may underlie this variability; however, the specific determinants remain unclear. To identify genes affecting AAO, we have conducted a genome-wide association study in Japanese patients with ALS (discovery cohort: n?=?1808; replication cohort: n?=?207). Here, we show that the minor A allele of rs113161727 at the ADAM29-GPM6A locus is associated with a younger AAO in the discovery cohort (effect, -4.27 years; p?=?4.60 × 10-8); this finding has been confirmed in the replication cohort (p?=?0.0068) and meta-analysis (p?=?1.08 × 10?9). Among 65 ALS patients with a SOD1 mutation, the AAO has been found to be 10.2 years younger in those with the A allele than in those without it (p?=?0.002). This variant correlates with GPM6A upregulation in iPSC-derived motor neurons, suggesting GPM6A as a candidate AAO modifier. Overall, our study highlights the impact of genetic modifiers on ALS heterogeneity and provides a potential target for delaying disease onset. en-copyright= kn-copyright= en-aut-name=NakamuraRyoichi

Central Retinal Vein Occlusion With Differential Long-Term Outcomes Following Cardiac Surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bilateral central retinal vein occlusion (CRVO) is rare and is associated with systemic diseases such as hypertension, diabetes, dyslipidemia, and coagulopathy. In this study, we showed that the sequential development of bilateral CRVO in an elderly patient was related to increased venous pressure in the right heart system. A 71-year-old man developed CRVO in the right eye, and one year later, he developed CRVO in the left eye. He had undergone pacemaker implantation for sick sinus syndrome 10 years earlier and had started hemodialysis three months prior for chronic renal failure, probably caused by hypertensive nephrosclerosis. The right CRVO resulted in neovascular glaucoma and loss of light perception despite intensive treatment with panretinal laser photocoagulation, intravitreal bevacizumab injection, and additional laser therapy. In contrast, the left CRVO remained at an impending stage, was treated only with panretinal laser photocoagulation, and had a favorable outcome for 11 years until his death. In retrospect, half a year after the onset of left CRVO, the patient underwent open-heart surgery to repair aortic, mitral, and tricuspid valve regurgitation through aortic valve replacement, mitral valve annuloplasty, and tricuspid valve annuloplasty, respectively. Based on the temporal sequence of events, elevated venous pressure due to right heart dysfunction may have contributed to the poor outcome of the right CRVO, whereas improvement of venous stasis after cardiac surgery may have led to the better long-term outcome of the left CRVO. Venous stasis in the right heart system should therefore be considered an underlying factor in the development of bilateral CRVO. 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=MasudaZenichi en-aut-sei=Masuda en-aut-mei=Zenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugiyamaHiroki en-aut-sei=Sugiyama en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Ophthalmology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University, Okayama University Hospital kn-affil= affil-num=2 en-affil=Cardiovascular Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Cardiovascular Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Cardiovascular Medicine and Center for Advanced Heart Failure, Okayama University Hospital kn-affil= en-keyword=aortic valve regurgitation kn-keyword=aortic valve regurgitation en-keyword=aortic valve replacement kn-keyword=aortic valve replacement en-keyword=bevacizumab kn-keyword=bevacizumab en-keyword=bilateral central retinal vein occlusion kn-keyword=bilateral central retinal vein occlusion en-keyword=intravitreal injection kn-keyword=intravitreal injection en-keyword=mitral valve annuloplasty kn-keyword=mitral valve annuloplasty en-keyword=mitral valve regurgitation kn-keyword=mitral valve regurgitation en-keyword=panretinal laser photocoagulation kn-keyword=panretinal laser photocoagulation en-keyword=tricuspid valve annuloplasty kn-keyword=tricuspid valve annuloplasty en-keyword=tricuspid valve regurgitation kn-keyword=tricuspid valve regurgitation END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue= article-no= start-page=489 end-page=492 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=Favorable outcomes of epilepsy with gait-induced seizures after resection of the unilateral supplementary motor area en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Gait-induced seizures are a rare manifestation of reflex epilepsy. Pathophysiology of this phenomenon has not been fully understood.
Case presentation: A 28-year-old woman presented with a long history of “falls” following paroxysmal bilateral leg stiffness triggered by walking. Scalp electroencephalogram (EEG) revealed low-amplitude rhythmic beta activity, maximal at the Cz electrode, during these events. Magnetoencephalography demonstrated repetitive sharp waves source-localized to the right primary motor cortex. Multiple anti-seizure medications failed to improve her symptoms; however, the clinical manifestation was consistent with epilepsy with gait-induced seizures. Intracranial subdural EEG recording was performed and confirmed ictal activity originating from the right supplementary motor area. Resection of this area resulted in complete resolution of her symptoms.
Discussion: This is the first reported case of successful resective surgery for epilepsy with gait-induced seizure. Brain networks involving cortical regions responsible for the initiation or execution of walking presumably played a key role in the generation of gait-induced seizures. Careful assessment using non-invasive neurophysiological studies facilitated accurate diagnosis, successful intracranial recordings, and effective resective surgery. en-copyright= kn-copyright= en-aut-name=KodamaSatoshi en-aut-sei=Kodama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuniiNaoto en-aut-sei=Kunii en-aut-mei=Naoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShirotaYuichiro en-aut-sei=Shirota en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChouTakusei en-aut-sei=Chou en-aut-mei=Takusei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawaiMizuho en-aut-sei=Kawai en-aut-mei=Mizuho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShimadaSeijiro en-aut-sei=Shimada en-aut-mei=Seijiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MaedaMeiko en-aut-sei=Maeda en-aut-mei=Meiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=HamadaMasashi en-aut-sei=Hamada en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IkemuraMasako en-aut-sei=Ikemura en-aut-mei=Masako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SaitoYuko en-aut-sei=Saito en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=AkamatsuNaoki en-aut-sei=Akamatsu en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=UeharaTaira en-aut-sei=Uehara en-aut-mei=Taira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=SaitoNobuhito en-aut-sei=Saito en-aut-mei=Nobuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=TodaTatsushi en-aut-sei=Toda en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=2 en-affil=Department of Neurosurgery, Jichi Medical University kn-affil= affil-num=3 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=4 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=5 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=6 en-affil=Department of Neurosurgery, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=7 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo 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=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=10 en-affil=Department of Pathology, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=11 en-affil=Department of Neuropahtology (Brain Bank for Aging Research), Tokyo Metropoliran Institute for Geriatrics and Gerontology kn-affil= affil-num=12 en-affil=Department of Neurology, International University of Health and Walfare Narita Hospital kn-affil= affil-num=13 en-affil=Department of Neurology, International University of Health and Walfare Narita Hospital kn-affil= affil-num=14 en-affil=Department of Neurosurgery, Graduate School of Medicine, The University of Tokyo kn-affil= affil-num=15 en-affil=Department of Neurology, Graduate School of Medicine, The University of Tokyo kn-affil= en-keyword=Reflex epilepsy kn-keyword=Reflex epilepsy en-keyword=Intracranial electroencephalogram (EEG) kn-keyword=Intracranial electroencephalogram (EEG) en-keyword=Electrocorticogram kn-keyword=Electrocorticogram en-keyword=magnetoencephalogram (MEG) kn-keyword=magnetoencephalogram (MEG) en-keyword=SMA kn-keyword=SMA 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=20251203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Novel in-frame duplication variant of SOD1 in a Japanese family with familial amyotrophic lateral sclerosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: To analyze the cases of a family with a novel in-frame duplication variant (NM_000454.5:c.357_357?+?2dup, p.Val120dup) of SOD1 and a structural model of the mutated SOD1 protein. Methods: The clinical profiles of three patients in the family were analyzed, including the neuropathological findings of the proband’s mother. Genetic analyses were conducted for three patients. cDNA and in silico structural analyses were performed to evaluate the effects of duplication variants on the structure of SOD1. Results: The clinical features of the patients included predominant involvement of the lower motor neurons, asymmetric onset of motor symptoms in the lower limbs, and a relatively rapid progression of muscular weakness and respiratory insufficiency. Neuropathological findings revealed severe loss of spinal cord motor neurons, and immunohistochemistry using an anti-misfolded SOD1 antibody revealed aggregates in the spinal cord. Genetic analyses revealed a c.357_357?+?2dup at the exon 4?intron 4 boundary of SOD1 in three patients. cDNA analysis of the proband suggested the presence of a valine (p.Val120dup) duplication in the heterozygous state, and the SOD1 transcript level showed no significant differences from those of healthy controls. In silico structural analyses predicted that p.Val120dup could affect the structure of the β-barrels and copper ion binding site of SOD1, suggesting an abnormal conformation of SOD1 that is predicted to interfere with the binding of copper ions. Conclusion: We identified a novel in-frame duplication variant in the C-terminus of β7 of SOD1. This genotype?structure?phenotype study of SOD1 provides valuable insights into disease-causing mechanisms. en-copyright= kn-copyright= en-aut-name=NakajimaMasanori en-aut-sei=Nakajima

en-abstract= kn-abstract=Background: Fabry disease (FD) is an important disease in the cardiovascular field because a significant proportion of patients with FD die from cardiac lesions.
Methods: A multicenter prospective registration study of patients with FD throughout Japan was designed. The baseline clinical characteristics of 175 patients are presented here.
Results: The mean ages at enrolment and at diagnosis were 52 ± 16 and 43 ± 18 years, respectively, with men accounting for 38 % of the patients. In the cohort, 24 % of the patients had the classical hemizygote male type, whereas 14 % had the late-onset male type, and 62 % had the heterozygote female type. On electrocardiography data at enrolment in 92 patients with left ventricular hypertrophy (LVH) (maximum LV wall thickness > 12 mm), 12 % showed a short PQ interval (< 120 msec), and 33 % had a short PendQ interval (? 40 msec). The Sokolow-Lyon voltage was high (6.1 ± 13.1 mv). Regarding the distribution of LVH patterns, 77 % of the patients showed concentric diffuse LVH, 16 % of the patients had asymmetric septal hypertrophy, and 1 % of the patients had hypertrophy confined to the LV apex. With regard to implantation of cardiac devices, permanent pacemakers had been implanted in 5 % of the patients and defibrillators had been implanted in 12 patients (7 %), for primary prevention in nine patients and for secondary prevention in three patients.
Conclusion: As the first large-scale prospective registry of FD patients in Japan, this study has provided valuable baseline data for the cardiac features and management of FD. en-copyright=

earthquake en-subtitle= kn-subtitle= en-abstract= kn-abstract=An Mw 7.5 earthquake occurred at 16:10 JST on January 1, 2024 at a depth of 16 km on the Noto Peninsula, central Japan. This earthquake was the second-largest intraplate earthquake recorded in Japan during 120 years of seismic observation, and it caused approximately 100 km of coastal seafloor emergence along the peninsula's northern coast. Herein, we mapped the emergence of this coastal seafloor and measured the uplift along the coast. The movement of the coastline led to the emergence of approximately 4.4 km2 of seafloor, which is continuous and probably the longest in the world. We determined the uplift distribution along the coast using the white remains of a reddish seaweed called Corallina pilulifera. Its upper limit exhibited a distinct horizontal line, effectively representing the uplift amount throughout the peninsula. Two large, uplifted regions were identified, around Cape Saruyama (5.21 m) in the west and Cape Kurasaki (2.70 m) in the north. Although active offshore submarine faults have been extensively researched, the fault traces remain poorly defined because they are primarily interpreted from seismic reflection profiles. We identified the distribution of active submarine faults using anaglyph-type stereoscopic images, confirming the subsurface deformation structure seen through the seismic reflection profiles. The main fault trace is primarily straight and contiguous with the nearby north coast. The uplift amount is greater near the active fault traces on the north side and diminishes sharply with increasing distance from these faults, indicating a southward tilt of surface uplift related to the active submarine faults. en-copyright= kn-copyright= en-aut-name=GotoHideaki en-aut-sei=Goto en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamanakaTomoru en-aut-sei=Yamanaka en-aut-mei=Tomoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MakitaTomohiro en-aut-sei=Makita en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IwasaYoshiya en-aut-sei=Iwasa en-aut-mei=Yoshiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OguraTakuro en-aut-sei=Ogura en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KagoharaKyoko en-aut-sei=Kagohara en-aut-mei=Kyoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KumaharaYasuhiro en-aut-sei=Kumahara en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SuzukiYasuhiro en-aut-sei=Suzuki en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MattaNobuhisa en-aut-sei=Matta en-aut-mei=Nobuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AokiTatsuto en-aut-sei=Aoki en-aut-mei=Tatsuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MoriWataru en-aut-sei=Mori en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HaranishiKenta en-aut-sei=Haranishi en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=NakataTakashi en-aut-sei=Nakata en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Hiroshima University kn-affil= affil-num=2 en-affil=Natural History Museum and Institute Chiba kn-affil= affil-num=3 en-affil=Hiroshima University kn-affil= affil-num=4 en-affil=University of Teacher Education Fukuoka kn-affil= affil-num=5 en-affil=Hyogo University of Teacher Education kn-affil= affil-num=6 en-affil=Yamaguchi University kn-affil= affil-num=7 en-affil=Hiroshima University kn-affil= affil-num=8 en-affil=Nagoya University kn-affil= affil-num=9 en-affil=Okayama University kn-affil= affil-num=10 en-affil=Kanazawa University kn-affil= affil-num=11 en-affil=Hiroshima University kn-affil= affil-num=12 en-affil=Hiroshima University kn-affil= affil-num=13 en-affil=Hiroshima University kn-affil= en-keyword=Active submarine fault kn-keyword=Active submarine fault en-keyword=Tectonic landform kn-keyword=Tectonic landform en-keyword=Coseismic coastal uplift kn-keyword=Coseismic coastal uplift en-keyword=Noto Peninsula kn-keyword=Noto Peninsula en-keyword=Sea of Japan kn-keyword=Sea of Japan END start-ver=1.4 cd-journal=joma no-vol=468 cd-vols= no-issue= article-no= start-page=109497 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Surface exposure ages of middle?late Pleistocene marine and fluvial terraces along the northern and southern Sanriku coasts, Northeast Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=To estimate long-term rates of coastal uplift along the northern Pacific coast of Northeast Japan, we determined the surface exposure ages of marine and fluvial terraces based on terrestrial in situ cosmogenic radionuclide dating of exposed bedrock surfaces. Based on reinterpretation of marine and fluvial terraces, we collected samples from the northern and southern Sanriku coast. The surface exposure ages from 10Be concentrations in quartz calculated from the measured 10Be/9Be ratios commonly suggest MIS 5 and MIS 7 for the marine and fluvial terraces and averaged coastal uplift rates of ca. 0.25?±?0.15 and 0.4?mm/yr along the northern and southern Sanriku coast at intermediate timescales. The results may demonstrate different styles of crustal strain accommodation in the northern Northeast Japan arc above the subducting Pacific plate. en-copyright= kn-copyright= en-aut-name=WakasaSachi en-aut-sei=Wakasa en-aut-mei=Sachi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshiyamaTatsuya en-aut-sei=Ishiyama en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HirouchiDaisuke en-aut-sei=Hirouchi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MattaNobuhisa en-aut-sei=Matta en-aut-mei=Nobuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujitaNatsuko en-aut-sei=Fujita en-aut-mei=Natsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=EchigoTomoo en-aut-sei=Echigo en-aut-mei=Tomoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Institute of Regional Innovation, Hirosaki University kn-affil= affil-num=2 en-affil=Earthquake Research Institute, University of Tokyo kn-affil= affil-num=3 en-affil=Faculty of Education, Shinshu University kn-affil= affil-num=4 en-affil=Faculty of Education, Okayama University kn-affil= affil-num=5 en-affil=Tono Geoscience center, Japan Atomic Energy Agency kn-affil= affil-num=6 en-affil=Kankyo Chisitsu, Co. kn-affil= en-keyword=Marine terrace kn-keyword=Marine terrace en-keyword=Exposure age kn-keyword=Exposure age en-keyword=10Be kn-keyword=10Be en-keyword=Coastal uplift kn-keyword=Coastal uplift END start-ver=1.4 cd-journal=joma no-vol=94 cd-vols= no-issue=3 article-no= start-page=401 end-page=407 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=Effect of Storage Temperature and a Sugar-ester Edible Coating on Postharvest Quality and Storage Life of ‘Fuyu’ Persimmon (Diospyros kaki Thunb.) en-subtitle= kn-subtitle= en-abstract= kn-abstract=In ‘Fuyu’ persimmons (Diospyros kaki Thunb.), crunchiness is a preferred postharvest attribute among both distributors and consumers. The present study first examined softening characteristics during storage at 0, 5, 10, 15, 20, and 25°C. Fruit stored at 0°C remained firm for 84 d, while that stored at 5°C had a 100% softening rate within 35 d. At 10 and 15°C, over 70% of fruit softened within 49 d and 63 d, respectively. The softening rate was relatively slower at 20 and 25°C, with only 27% softened fruit after 56 d at 25°C. The potential of a newly developed sugar-ester (SE) edible coating to delay fruit softening and maintain postharvest quality was then assessed during storage at 0 and 25°C. Uncoated fruit stored at 0°C for 56 d developed chilling injury (CI) symptoms (rapid fruit softening and peel browning) within 2 d of rewarming at 20°C. These CI symptoms were notably mitigated in SE-coated fruit. At 25°C, SE coating also delayed fruit softening and peel color change in addition to reducing fruit shrinkage. In conclusion, in ‘Fuyu’ persimmons ambient temperature (20?25°C) storage in combination with an edible SE coating is recommended for the high demand Christmas and new year seasons and 0°C storage with an edible SE coating is suitable for longer storage and distribution. en-copyright= kn-copyright= en-aut-name=MuqadasMaqsood en-aut-sei=Muqadas en-aut-mei=Maqsood kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= 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=2 ORCID= en-aut-name=OhashiKyohei en-aut-sei=Ohashi en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OtsukiTakumi en-aut-sei=Otsuki en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YanoChikara en-aut-sei=Yano en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HejaziZiaurrahman en-aut-sei=Hejazi en-aut-mei=Ziaurrahman kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HiraNatsuki en-aut-sei=Hira en-aut-mei=Natsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life Science, Natural Science and Technology Okayama University kn-affil= affil-num=2 en-affil=Faculty of Life and Environmental Sciences, University of Tsukuba kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life Science, Natural Science and Technology Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life Science, Natural Science and Technology Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life Science, Natural Science and Technology Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Agriculture, University of Miyazaki kn-affil= affil-num=7 en-affil=Shiga R&D Center, Mitsubishi Chemical Corporation kn-affil= affil-num=8 en-affil=Graduate School of Environmental, Life Science, Natural Science and Technology Okayama University kn-affil= affil-num=9 en-affil=Graduate School of Environmental, Life Science, Natural Science and Technology Okayama University kn-affil= en-keyword=chilling injury kn-keyword=chilling injury en-keyword=long-term storage kn-keyword=long-term storage en-keyword=postharvest life kn-keyword=postharvest life en-keyword=shrinkage kn-keyword=shrinkage en-keyword=softening kn-keyword=softening END start-ver=1.4 cd-journal=joma no-vol=63 cd-vols= no-issue=13 article-no= start-page=1863 end-page=1872 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240701 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Activated CD4+ T Cell Proportion in the Peripheral Blood Correlates with the Duration of Cytokine Release Syndrome and Predicts Clinical Outcome after Chimeric Antigen Receptor T Cell Therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective Chimeric antigen receptor (CAR) T cell therapy is an emerging and effective therapy for relapsed or refractory diffuse large B cell lymphoma (R/R DLBCL). The characteristic toxicities of CAR T cell therapy include cytokine release syndrome (CRS) and prolonged cytopenia. We investigated the factors associated with these complications after CAR T cell therapy by analyzing lymphocyte subsets following CAR T cell infusion.
Methods We retrospectively analyzed peripheral blood samples on days 7, 14, and 28 after tisagenlecleucel (tisa-cel) infusion by flow cytometry at our institution between June 2020 and September 2022.
Patients Thirty-five patients with R/R DLBCL who received tisa-cel therapy were included.
Results A flow cytometry-based analysis of blood samples from these patients revealed that the proportion of CD4+CD25+CD127+ T cells (hereafter referred to as "activated CD4+ T cells" ) among the total CD4+ T cells on day 7 after tisa-cel infusion correlated with the duration of CRS (r=0.79, p<0.01). In addition, a prognostic analysis of the overall survival (OS) using time-dependent receiver operating characteristic curves indicated a significantly more favorable OS and progression-free survival of patients with a proportion of activated CD4+ T cells among the total CD4+ T cells <0.73 (p=0.01, and p<0.01, respectively).
Conclusion These results suggest that the proportion of activated CD4+ T cells on day 7 after tisa-cel infusion correlates with the CRS duration and predicts clinical outcomes after CAR T cell therapy. Further studies with a larger number of patients are required to validate these observations. 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=AsadaNoboru en-aut-sei=Asada en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IkegawaShuntaro en-aut-sei=Ikegawa en-aut-mei=Shuntaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiwaraHideaki en-aut-sei=Fujiwara en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KamoiChihiro en-aut-sei=Kamoi en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=NishimoriHisakazu en-aut-sei=Nishimori en-aut-mei=Hisakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujiiKeiko en-aut-sei=Fujii en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsuokaKen-ichi en-aut-sei=Matsuoka en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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= affil-num=1 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Japan kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Division of Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=9 en-affil=Division of Blood Transfusion, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= en-keyword=chimeric antigen receptor T cell therapy kn-keyword=chimeric antigen receptor T cell therapy en-keyword=diffuse large B cell lymphoma kn-keyword=diffuse large B cell lymphoma en-keyword=flow cytometry kn-keyword=flow cytometry en-keyword=cytokine release syndrome kn-keyword=cytokine release syndrome en-keyword=prolonged cytopenia kn-keyword=prolonged cytopenia END start-ver=1.4 cd-journal=joma no-vol=198 cd-vols= no-issue=1 article-no= start-page=kiaf196 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=Role of polar localization of the silicon transporter OsLsi1 in metalloid uptake by rice roots en-subtitle= kn-subtitle= en-abstract= kn-abstract=Low silicon (Si) rice 1 (OsLsi1) is a key transporter mediating Si uptake in rice (Oryza sativa). It is polarly localized at the distal side of the root exodermis and endodermis. Although OsLsi1 is also permeable to other metalloids, such as boron (B), germanium (Ge), arsenic (As), antimony (Sb), and selenium (Se), the role of its polar localization in the uptake of these metalloids remains unclear. In this study, we investigated the role of OsLsi1 polar localization in metalloid uptake by examining transgenic rice plants expressing polarly or nonpolarly localized OsLsi1 variants. Loss of OsLsi1 polar localization resulted in decreased accumulation of Ge, B, and As in shoots but increased Sb accumulation, while Se accumulation remained unaffected under normal conditions. Experiments with varying B concentrations revealed that B uptake is significantly lower at low B concentrations (0.3 to 3?μm) but higher at high B concentrations (300?μm) in plants expressing nonpolarly localized OsLsi1, despite the similar B permeability of both OsLsi1 variants in Xenopus oocytes and their comparable protein abundance in roots. Additionally, the loss of OsLsi1 polarity did not affect the abundance, localization, or high B-induced degradation of the borate transporter 1 (OsBOR1), an efflux transporter that cooperates with OsLsi1 for B uptake. Taken together, our findings demonstrate that the polar localization of OsLsi1 plays a critical role in regulating metalloid uptake, depending on the presence or absence of efflux transporters cooperating with OsLsi1. en-copyright= kn-copyright= en-aut-name=KonishiNoriyuki en-aut-sei=Konishi en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Mitani-UenoNamiki en-aut-sei=Mitani-Ueno en-aut-mei=Namiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaJian Feng en-aut-sei=Ma en-aut-mei=Jian Feng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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= END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=4 article-no= start-page=e70051 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=Interaction between nuclear‐translocated cellular communication network factor 2 and purine‐rich box 1 regulates the expression of fibrosis‐related genes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cellular communication network factor 2 (CCN2) with a nuclear localization signal-like peptide is known to promote fibrosis. However, translocation of CCN2 into the nucleus and its role in fibrosis remain unclear. We hypothesized that nuclear-translocated CCN2 is associated with purine-rich box 1 (PU.1), which is a transcription factor regulating the differentiation of myofibroblasts. Western blot analysis of the cytoplasmic and nuclear fractions of cell lysate and immunofluorescence analysis revealed that CCN2 was detectable in both the cytoplasm and nuclei of murine fibroblastic NIH3T3 cells. Additionally, chromatin immunoprecipitation (IP)-PCR and an electrophoretic mobility shift assay revealed that recombinant CCN2 protein bound to the regulatory region of Spi1, which encodes PU.1. Furthermore, IP-Western blot analysis showed that CCN2 interacted with PU.1. Finally, the forced expression of both Ccn2 and Spi1 significantly promoted the production of angiotensin II, and increased fibrosis-related molecules, such as Col1a1 and Acta2, at the gene and protein levels. These findings indicate that CCN2 translocated to the nucleus interacts with PU.1 and that the complex promotes the markers of myofibroblast differentiation, suggesting that CCN2 plays an important role in fibrosis via cooperation with PU.1, as a transcription co-factor. en-copyright= kn-copyright= en-aut-name=NguyenXuan Thi en-aut-sei=Nguyen en-aut-mei=Xuan Thi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KubotaSatoshi en-aut-sei=Kubota en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Advanced Research Center for Oral and Craniofacial Sciences, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences Okayama Japan kn-affil= affil-num=4 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=cellular communication network factor 2 (CCN2) kn-keyword=cellular communication network factor 2 (CCN2) en-keyword=fibrosis kn-keyword=fibrosis en-keyword=myofibroblast kn-keyword=myofibroblast en-keyword=purine‐rich box 1 (PU.1) kn-keyword=purine‐rich box 1 (PU.1) en-keyword=transcription co‐factor kn-keyword=transcription co‐factor END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=4 article-no= start-page=e70082 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Case of Retinopathy?Sensory Neuropathy Syndrome With a Novel Compound Heterozygous FLVCR1 Variant en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Aims: Retinopathy?sensory neuropathy syndrome (RETSNS), also known as posterior column ataxia with retinitis pigmentosa (PCARP), is a rare neurodegenerative disorder that is caused by biallelic pathogenic variants in FLVCR1. Here, we report a case of a Japanese patient with RETSNS.
Methods: Clinical, neuroradiological, and electrophysiological findings were documented. Whole-genome sequencing was performed. Subcloning was carried out to confirm compound heterozygosity. A functional assay was performed to assess the pathogenicity of the variants.
Results: The patient showed retinitis pigmentosa and sensory ataxia. Over the course of the disease, autonomic dysfunction has become increasingly evident. Despite consanguinity in the family, whole-genome sequencing identified two heterozygous variants in FLVCR1 (c.369T>G, p.Phe123Leu and c.733A>G, p.Asn245Asp). Cloning of the PCR product followed by Sanger sequencing indicated compound heterozygosity of the variants. Immunocytochemistry of HEK293FT cells transfected with plasmids containing wild-type or variant FLVCR1 cDNA demonstrated altered subcellular localization of the variant FLVCR1 proteins, characterized by reduced membrane localization.
Interpretation: We report a novel variant in FLVCR1 causing RETSNS. The functional assay supports the pathogenicity of the variants. en-copyright= kn-copyright= en-aut-name=NakanoYumiko en-aut-sei=Nakano en-aut-mei=Yumiko 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=DeguchiKentaro en-aut-sei=Deguchi en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsuokaChika en-aut-sei=Matsuoka en-aut-mei=Chika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawanoTomohito en-aut-sei=Kawano en-aut-mei=Tomohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TairaYuki en-aut-sei=Taira en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuoAyaka en-aut-sei=Matsuo en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OsakadaYosuke en-aut-sei=Osakada en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=NomuraEmi en-aut-sei=Nomura en-aut-mei=Emi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 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=12 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=13 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=14 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 City General Medical Center 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=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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= affil-num=12 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=FLCVR1 kn-keyword=FLCVR1 en-keyword=functional analysis kn-keyword=functional analysis en-keyword=posterior column ataxia with retinitis pigmentosa kn-keyword=posterior column ataxia with retinitis pigmentosa en-keyword=subcellular localization kn-keyword=subcellular localization END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=4 article-no= start-page=244 end-page=249 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250527 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Identification of New Repeat Expansion Diseases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Through a genetic study of benign adult familial myoclonus epilepsy (BAFME) type 1, TTTCA and TTTTA repeat expansions have been identified in intron 4 of SAMD12. Lengths of expanded repeats inversely correlated with age at onset of epilepsy. Gain-of-toxic function mechanisms are suggested by the presence of UUUCA-repeat-containing RNA foci. From families with BAFME who did not have repeat expansions in SAMD12, we identified expanded TTTCA and TTTTA repeats in TNRC6A and RAPGEF2. These findings indicated a strong correlation between the repeat motif and the phenotype, leading to the identification of other types of BAFME. We then conducted genetic analysis of neuronal intranuclear inclusion disease (NIID), oculopharyngeal myopathy with leukoencephalopathy (OPML), and oculopharyngodistal myopathy (OPDM). From the observation that NIID, OPML, and OPDM, in addition to fragile X-associated tremor/ataxia syndrome, have shared clinical features, a direct search for CGG repeat expansions successfully led to the identification of the causative genes. Here, I review recent studies on repeat expansions. en-copyright= kn-copyright= en-aut-name=IshiuraHiroyuki en-aut-sei=Ishiura en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Neurology, Okayama UniversityGraduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251216 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of size factors and velocity of impinging diesel spray flames on wall heat transfer en-subtitle= kn-subtitle= en-abstract= kn-abstract=To examine the effects of size and velocity of impinging diesel spray flames on wall heat transfer, this study conducted visualization of the spray flame and measurements of wall heat flux in a constant volume vessel. The impinging flame velocity was varied by adjusting the injection velocity. To vary the flame size independently of the flame velocity, the nozzle orifice diameter and the nozzle-to-wall distance were varied under similarity conditions, while maintaining a constant ratio of nozzle-to-wall distance to orifice diameter. Care was taken to minimize wall interference from the liquid phase and unburned regions of the spray flame by employing a high cetane number fuel and increasing the nozzle-to-wall distance. The experimental results showed that the wall heat flux increased as the impinging velocity increased, and the flame width decreased. The power-law correlations between the Nusselt and Reynolds numbers were determined based on the experimental results, revealing that the exponent of the Reynolds number reaches a local minimum at the impingement point. As the radial displacement from the impingement point increases, the exponent of the Reynolds number approaches approximately 0.8, which is a typical value for turbulent wall flow. en-copyright= kn-copyright= en-aut-name=KobashiYoshimitsu en-aut-sei=Kobashi en-aut-mei=Yoshimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiraiRyoga en-aut-sei=Hirai en-aut-mei=Ryoga kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShibataGen en-aut-sei=Shibata en-aut-mei=Gen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OgawaHideyuki en-aut-sei=Ogawa en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Engineering, Hokkaido University kn-affil= affil-num=3 en-affil=Graduate School of Engineering, Hokkaido University kn-affil= affil-num=4 en-affil=Graduate School of Engineering, Hokkaido University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue= article-no= start-page=100624 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Assessing water resources availability and crop performance under climate change in Kenya's Bura irrigation scheme using SWAT and AquaCrop en-subtitle= kn-subtitle= en-abstract= kn-abstract=The current study focused on Tana River Basin in Kenya, home to the Bura irrigation scheme (BIS). The BIS faces water supply shortages during critical months of crop development. This study aimed to evaluate the available water resources and crop performance using the Soil and Water Assessment Tool (SWAT) and AquaCrop, respectively, under historical and future shared socioeconomic pathways (SSPs) at the BIS. SWAT estimated the total available flows (TAF) at the BIS intake, whereas AquaCrop estimated crop water requirements (CWR), yields, and water productivity (Wpet) of rice and maize at various carbon (IV) oxide (CO2) levels. The study suggested that the TAF will remain relatively low during the early critical crop development stages in the main cropping season, August-October. Maize yields remained steady over the two cropping seasons under both constant and elevated CO2 levels in the historical and future periods, as opposed to those of rice. Elevated CO2 levels led to diminishing CWR. Moreover, rice showed a stronger response to elevated CO2 than maize. As a result, maize which is less affected by variations in CO2 and temperatures and has less crop water requirements will be better suited than rice for cultivation in the BIS under climate change. To ensure a sustainable water supply in the scheme, the government should increase rainwater harvesting during periods of high TAF. Moreover, there should be a focus on introducing crops that are tolerant to water and temperature stresses and that can reap the most from the elevated CO2 levels. en-copyright= kn-copyright= en-aut-name=WambuaDaniel Mwendwa en-aut-sei=Wambua en-aut-mei=Daniel Mwendwa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SomuraHiroaki en-aut-sei=Somura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoroizumiToshitsugu en-aut-sei=Moroizumi en-aut-mei=Toshitsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=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 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= en-keyword=Climate change kn-keyword=Climate change en-keyword=Shared socioeconomic pathways kn-keyword=Shared socioeconomic pathways en-keyword=Sustainable water management kn-keyword=Sustainable water management en-keyword=Temperature stress days kn-keyword=Temperature stress days en-keyword=Water stress days kn-keyword=Water stress days en-keyword=Water productivity kn-keyword=Water productivity en-keyword=Yields kn-keyword=Yields END start-ver=1.4 cd-journal=joma no-vol=992 cd-vols= no-issue=1 article-no= start-page=27 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Observing Supernova Neutrino Light Curves with Super-Kamiokande. VI. A Practical Data Analysis Technique Considering Realistic Experimental Backgrounds en-subtitle= kn-subtitle= en-abstract= kn-abstract=Neutrinos from supernovae, especially those emitted during the late phase of core collapse, are essential for understanding the final stages of massive star evolution. We have been dedicated to developing methods for the analysis of neutrinos emitted during the late phase and observed at Super-Kamiokande (SK). Our previous studies have successfully demonstrated the potential of various analysis methods in extracting essential physical properties; however, the lack of background consideration has limited their practical application. In this study, we address this issue by incorporating a realistic treatment of the experimental signal and background events with the on-going SK experiment. We therefore optimize our analysis framework to reflect realistic observational conditions, including both signal and background events. Using this framework we study several long-time supernova models, simulating the late phase neutrino observation in SK and focusing in particular on the identification of the last observed event. We discuss the possibility of model discrimination methods using timing information from this last observed event. en-copyright= kn-copyright= en-aut-name=NakanishiFumi en-aut-sei=Nakanishi en-aut-mei=Fumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakazatoKen’ichiro en-aut-sei=Nakazato en-aut-mei=Ken’ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaradaMasayuki en-aut-sei=Harada en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KoshioYusuke en-aut-sei=Koshio en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AkahoRyuichiro en-aut-sei=Akaho en-aut-mei=Ryuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AshidaYosuke en-aut-sei=Ashida en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HaradaAkira en-aut-sei=Harada en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MoriMasamitsu en-aut-sei=Mori en-aut-mei=Masamitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SumiyoshiKohsuke en-aut-sei=Sumiyoshi en-aut-mei=Kohsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SuwaYudai en-aut-sei=Suwa en-aut-mei=Yudai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=WendellRoger A. en-aut-sei=Wendell en-aut-mei=Roger A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ZaizenMasamichi en-aut-sei=Zaizen en-aut-mei=Masamichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Physics, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Arts and Science, Kyushu University kn-affil= affil-num=3 en-affil=Kamioka Observatory, Institute for Cosmic Ray Research, The University of Tokyo kn-affil= affil-num=4 en-affil=Department of Physics, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Science and Engineering, Waseda University kn-affil= affil-num=6 en-affil=Department of Physics, Tohoku University kn-affil= affil-num=7 en-affil=National Institute of Technology, Ibaraki College kn-affil= affil-num=8 en-affil=Division of Science, National Astronomical Observatory of Japan kn-affil= affil-num=9 en-affil=National Institute of Technology, Numazu College kn-affil= affil-num=10 en-affil=Department of Earth Science and Astronomy, The University of Tokyo kn-affil= affil-num=11 en-affil=Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU, WPI), Todai Institutes for Advanced Study, The University of Tokyo kn-affil= affil-num=12 en-affil=Department of Earth Science and Astronomy, The University of Tokyo kn-affil= END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue= article-no= start-page=632 end-page=645 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Robust adhesion between solid-state hydroxyapatite and bone tissue through surface demineralization en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: Current bone adhesives typically lack adequate mechanical strength, long-term stability, or biocompatibility. To address these limitations, we designed a new adhesion strategy using a solid-state hydroxyapatite (HAp) adhesive in combination with bone surface demineralization.
Methods: Solid-state HAp adhesives were synthesized via wet chemical precipitation and heat treatment. Cortical bone specimens were partially demineralized with phosphoric acid (H3PO4) or ethylenediaminetetraacetic acid (EDTA), and characterized using scanning electron microscopy (SEM) and attenuated total reflectance?Fourier transform infrared spectroscopy (ATR-FTIR). Shear adhesion strength of HAp to demineralized bone was measured over time. In vivo fixation was assessed in rats using micro-computed tomography and histology. Statistical analysis used Tukey-Kramer tests after normality and variance checks.
Results: Although the HAp adhesive failed to adhere to non-demineralized bone, effective adhesion was achieved on the surface-demineralized bone tissue. Shear adhesion strength was significantly higher in EDTA-treated samples (238.4 kPa at 10 h) compared to H3PO4-treated samples (102.9 kPa at 1 h), with performance correlating with demineralization depth. ATR-FTIR and SEM analyses revealed that EDTA preserved collagen's triple-helix structure and free water content, both enhancing adhesion. Animal experiments confirmed stable fixation of HAp adhesive to demineralized bone tissue.
Conclusions: Surface demineralization enabled strong adhesion of the solid-state HAp adhesive to bone by exposing collagen swollen with water. Adhesion strength was influenced by structural changes in the demineralized layer, and the adhesive provided stable in vivo fixation, supporting its potential for bone-anchored biomedical applications. en-copyright= kn-copyright= en-aut-name=XieShichao en-aut-sei=Xie en-aut-mei=Shichao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkadaMasahiro en-aut-sei=Okada en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AoyagiHaruyuki en-aut-sei=Aoyagi en-aut-mei=Haruyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OtakaAkihisa en-aut-sei=Otaka en-aut-mei=Akihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YangXiaofeng en-aut-sei=Yang en-aut-mei=Xiaofeng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakanoTakayoshi en-aut-sei=Nakano en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoTakuya en-aut-sei=Matsumoto en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Division of Biomaterials Science and Engineering, Graduate School of Dentistry, Tohoku University kn-affil= affil-num=3 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Division of Materials and Manufacturing Science, Graduate School of Engineering, The University of Osaka kn-affil= affil-num=7 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Solid-state adhesive kn-keyword=Solid-state adhesive en-keyword=Hydroxyapatite kn-keyword=Hydroxyapatite en-keyword=Demineralized bone kn-keyword=Demineralized bone en-keyword=Collagen kn-keyword=Collagen en-keyword=Hydration kn-keyword=Hydration END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue= article-no= start-page=100998 end-page= 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=Robustness of the RGB image-based estimation for rice above-ground biomass by utilizing the dataset collected across multiple locations en-subtitle= kn-subtitle= en-abstract= kn-abstract=Above-ground biomass (AGB) is a critical phenotype representing crop growth. Non-invasive evaluations of AGB, including deep-learning-based red-green-blue (RGB) image analyses, are often specific to the training data. The robustness of the estimation model across untrained conditions is essential to monitor crop productivity globally, but it has yet to be fully assessed. This study aims to assess the robustness of a convolutional neural network (CNN) model for rice AGB estimation across five locations in three countries, and to demonstrate the feasibility of robust model via a practical approach. From transplanting to heading, 1957 RGB images were captured vertically downward over the rice canopy, covering approximately 1 m2. First, a base model was established using data collected from a single location. Then, its robustness was assessed using test datasets taken from the other four locations. The CNN model showed a significant variation in estimation accuracy across the untrained four locations, indicating insufficient robustness of the base model. Subsequently, we quantitatively tested the impact of improving training data diversity on model robustness by adding data from each of the four locations to the base model's training data. Adding at most 48 data points from a location achieved practical accuracy for the added location, with R2Ad above 0.8. Interestingly, adding data from one location sometimes improved the accuracy for other untrained locations as well. These findings suggest that collecting diverse training data for RGB-based estimation, combined with evaluation of robustness paves the way for on-site and instant AGB monitoring of rice. en-copyright= kn-copyright= en-aut-name=NakajimaKota en-aut-sei=Nakajima en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoKazuki en-aut-sei=Saito en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsujimotoYasuhiro en-aut-sei=Tsujimoto en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakaiToshiyuki en-aut-sei=Takai en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MochizukiAtsushi en-aut-sei=Mochizuki en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamaguchiTomoaki en-aut-sei=Yamaguchi en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IbrahimAli en-aut-sei=Ibrahim en-aut-mei=Ali kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MairouaSalifou Goube en-aut-sei=Mairoua en-aut-mei=Salifou Goube kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AndrianaryBruce Haja en-aut-sei=Andrianary en-aut-mei=Bruce Haja kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KatsuraKeisuke en-aut-sei=Katsura en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TanakaYu en-aut-sei=Tanaka en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=2 en-affil=International Rice Research Institute (IRRI) kn-affil= affil-num=3 en-affil=Japan International Research Center for Agricultural Sciences kn-affil= affil-num=4 en-affil=Japan International Research Center for Agricultural Sciences kn-affil= affil-num=5 en-affil=CHIBA Prefectural Agriculture and Forestry Research Center kn-affil= affil-num=6 en-affil=Faculty of Applied Biological Sciences, Gifu University kn-affil= affil-num=7 en-affil= Africa Rice Center (AfricaRice), Regional Station for the Sahel kn-affil= affil-num=8 en-affil=Africa Rice Center (AfricaRice) kn-affil= affil-num=9 en-affil=Laboratoire des Radioisotopes, Universit? d′Antananarivo kn-affil= affil-num=10 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=11 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Robustness kn-keyword=Robustness en-keyword=RGB image kn-keyword=RGB image en-keyword=Rice, Above-ground biomass kn-keyword=Rice, Above-ground biomass en-keyword=Convolutional neural network kn-keyword=Convolutional neural network END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=469 end-page=474 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Ileus Tube-Related Intussusception: A Case Report and Review of 80 Previously Reported Cases en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a rare case of ileus tube-related intussusception in an adult. A 56-year-old man with adhesive bowel obstruction was treated with a nasointestinal ileus tube. Although his condition initially improved, persistent abdominal pain led to the diagnosis of intussusception via CT imaging. Manual repositioning of the tube resolved the intussusception without the need for bowel resection. A review of 80 previously reported cases of ileus tube-associated intussusception (total 81 cases, 95 lesions) highlighted the timing of onset, treatment strategies, and precautions. Early detection and diagnosis are crucial to prevent severe complications and preserve bowel function. en-copyright= kn-copyright= en-aut-name=TsujiiTeruyuki en-aut-sei=Tsujii en-aut-mei=Teruyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=KimuraYuji en-aut-sei=Kimura en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatsubeRyoichi en-aut-sei=Katsube en-aut-mei=Ryoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwadouHironori en-aut-sei=Iwadou en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FunabikiSadami en-aut-sei=Funabiki en-aut-mei=Sadami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KamikawaYasuaki en-aut-sei=Kamikawa en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsudaTadakazu en-aut-sei=Matsuda en-aut-mei=Tadakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=2 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=3 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=4 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=5 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=6 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=7 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=8 en-affil=Department of Surgery, Matsuda Hospital kn-affil= en-keyword=nasointestinal ileus tube kn-keyword=nasointestinal ileus tube en-keyword=intussusception kn-keyword=intussusception en-keyword=small bowel obstruction kn-keyword=small bowel obstruction en-keyword=enterectomy kn-keyword=enterectomy en-keyword=conservative treatment kn-keyword=conservative treatment END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=451 end-page=455 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Recurrence of FVIII Inhibitor during Surgery in a Patient with Severe Hemophilia A Receiving Emicizumab Prophylaxis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Emicizumab, a bispecific monoclonal antibody, benefits patients with severe hemophilia A. It alters laboratory assessments of coagulation activity, requiring anti-idiotype monoclonal antibodies for accurate monitoring. A 64-year-old man, receiving emicizumab regularly, was admitted for laminoplasty. We planned to use FVIII replacement during the perioperative period after confirming the disappearance of inhibitors, monitoring coagulation activity with anti-idiotype monoclonal antibodies. Activated partial thromboplastin time was prolonged on postoperative day 2, prompting an immediate switch to eptacog alfa. The patient recovered without bleeding. This case underscores the necessity of anti-idiotype monoclonal antibodies for accurate monitoring. en-copyright= kn-copyright= en-aut-name=HagiharaMoe en-aut-sei=Hagihara en-aut-mei=Moe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SeikeKeisuke en-aut-sei=Seike en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HayashinoKenta en-aut-sei=Hayashino en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KinKyohei en-aut-sei=Kin en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HirataYuichi en-aut-sei=Hirata en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=KitamuraWataru en-aut-sei=Kitamura en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiwaraHideaki en-aut-sei=Fujiwara en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AsadaNoboru en-aut-sei=Asada en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= affil-num=1 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Division of Transfusion and Cell Therapy, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= en-keyword=emicizumab kn-keyword=emicizumab en-keyword=eptacog alfa kn-keyword=eptacog alfa en-keyword=hemophilia A kn-keyword=hemophilia A en-keyword=inhibitor kn-keyword=inhibitor en-keyword=anti-idiotype monoclonal antibodies to emicizumab kn-keyword=anti-idiotype monoclonal antibodies to emicizumab END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=445 end-page=449 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Perioperative Team Management Was Beneficially Associated with Prolonged Postoperative Hospital Stays after Long Lower-Abdominal Surgeries en-subtitle= kn-subtitle= en-abstract= kn-abstract=Our hospital began a PERIO program (perioperative patient management by a multi-disciplinary team from multiple departments) in 2016 to improve patient outcomes. We retrospectively analyzed the clinical effects of the PERIO program regarding the postoperative hospital stay (PHS) in the patients aged ? 18 years who underwent long lower-abdominal surgery at our hospital during the period April 2019 to March 2023. We excluded the cases of patients whose general anesthesia use was < 8 h, those for whom another surgery was performed simultaneously at another site, and emergency surgeries. The outcome was prolonged PHS, defined as exceeding the scheduled number of days specified in the patient’s clinical pathway. Among the 480 patients, prolonged PHS was observed for 270 patients (56.3%). In a multivariate logistic regression using advanced age, sex, high-risk general state, surgery requiring colon resection, serious adverse events (SAEs), and PERIO use, the following were associated with prolonged PHS: advance age (odds ratio [OR] 4.91, 95% confidence interval [CI]: 2.68-8.99, p=0.01), surgery requiring colon resection (OR 4.91, 95%CI: 2.68-8.99, p<0.001), SAE (OR 18.7, 95%CI: 7.22-48.2, p<0.001), and PERIO (OR 0.25, 95%CI: 0.13-0.47, p<0.001). The use of the PERIO program was thus beneficially associated with PHS after long lower-abdominal surgery. en-copyright= kn-copyright= en-aut-name=MatsumiJunya en-aut-sei=Matsumi en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Intensive Care Medicine, National Cancer Center Hospital kn-affil= en-keyword=hospital stay kn-keyword=hospital stay en-keyword=ERAS kn-keyword=ERAS en-keyword=surgery kn-keyword=surgery en-keyword=cancer kn-keyword=cancer en-keyword=perioperative management kn-keyword=perioperative management END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=437 end-page=444 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Frailty at 1 Month before ICU Admission Poses a Hospital Mortality Risk in Cancer Survivors whose Condition Has Deteriorated due to Medical Factors en-subtitle= kn-subtitle= en-abstract= kn-abstract=The optimal indications for intensive care unit (ICU) treatment for critically ill cancer survivors whose condition has deteriorated due to medical factors are unclear. To test our hypothesis that frailty before deterioration was associated with hospital mortality in this patient population, we retrospective analyzed the cases of the patients admitted to the ICU at the National Cancer Center Hospital, Japan (April 2014-March 2022). We excluded patients who underwent surgery within 28 days or were denied critical care within 24 h or admitted after cardiopulmonary arrest. Their Clinical Frailty Scale (CFS) scores at 1 month before ICU admission (Pre-ICU) were obtained. Frailty was defined as CFS scores ?4 points. We analyzed 298 admissions and observed that the mortality rate at hospital discharge was significantly higher in the frailty group (n=119). A multivariate analysis demonstrated that the following factors were significantly associated with hospital mortality: Pre-ICU frailty (OR 2.00, 95%CI: 1.19-3.36, p=0.009), cancer type (hematological: OR 2.93, 95%CI: 1.42-6.05, p=0.004), and Sequential Organ Failure Assessment score at ICU admission (OR 0.88, 95%CI: 0.82-0.95, p=0.0008). Frailty retrospectively assessed using the CFS at 1 month pre-ICU admission is a risk factor for hospital mortality in these cancer survivors. en-copyright= kn-copyright= en-aut-name=MatsumiJunya en-aut-sei=Matsumi en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoTetsufumi en-aut-sei=Sato en-aut-mei=Tetsufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Intensive Care Medicine, National Cancer Center Hospital kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Intensive Care Medicine, National Cancer Center Hospital kn-affil= en-keyword=frailty kn-keyword=frailty en-keyword=cancer survivor kn-keyword=cancer survivor en-keyword=clinical frailty scale kn-keyword=clinical frailty scale en-keyword=cancer kn-keyword=cancer en-keyword=critically ill kn-keyword=critically ill END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=421 end-page=429 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Thoron Inhalation and Cyclosporin A Treatment on Dextran Sulfate Sodium-Induced Oxidative Damage in Mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Radon (222Rn; Rn) and thoron (220Rn; Tn) inhalation have been reported to enhance antioxidant activity in various organs. However, the effects of Tn on the colon have not been investigated. This study aimed to clarify the effects of Tn inhalation, alone and in combination with cyclosporin A (CsA), on dextran sulfate sodium (DSS)-induced colitis, and the accompanying oxidative stress, in mice. Male BALB/c mice were subjected to continuous 8-day Tn inhalation (c-Tn, 533±128 Bq/m3) or alternate-day Tn inhalation over the same period (f-Tn, 577±63Bq/m3), followed by treatment with 3% DSS and either CsA or vehicle for 7 days. Although the disease activity index (DAI) decreased significantly by day 2 in the c-Tn group, scores remained significantly higher than those in the f-Tn group. In the c-Tn group, superoxide dismutase and catalase activity in the colon were significantly elevated compared with those in sham controls. Thus, DSS-induced damage was effectively inhibited in the earlier stages by the c-Tn mode of inhalation than by the f-Tn mode. These findings suggest that continuous Tn inhalation more effectively attenuated early colitis symptoms than alternate-day inhalation, potentially through upregulation of antioxidant defenses. Tn and CsA showed no combined effects. en-copyright= kn-copyright= en-aut-name=TanakaAyumi en-aut-sei=Tanaka en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaoeShota en-aut-sei=Naoe en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakenakaReiju en-aut-sei=Takenaka en-aut-mei=Reiju kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KanzakiNorie en-aut-sei=Kanzaki en-aut-mei=Norie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakodaAkihiro en-aut-sei=Sakoda en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamaokaKiyonori en-aut-sei=Yamaoka en-aut-mei=Kiyonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KataokaTakahiro en-aut-sei=Kataoka en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=5 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=6 en-affil=Faculty of Health Sciences, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=thoron kn-keyword=thoron en-keyword=DSS kn-keyword=DSS en-keyword=antioxidant activity kn-keyword=antioxidant activity en-keyword=CsA kn-keyword=CsA en-keyword=colon kn-keyword=colon END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=405 end-page=412 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Real-World Outcomes of Anti-Vascular Endothelial Growth Factor Therapy for Neovascular Age-Related Macular Degeneration in Patients Aged 85 or Older en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated the treatment outcomes of patients aged ?85 years with neovascular age-related macular degeneration (nAMD) who received anti-vascular endothelial growth factor (anti-VEGF) therapy using either treat-and-extend (TAE) or pro re nata (PRN) regimens for 1 year in real-world clinical practice. Eighty-five eyes from 85 patients were included. Among them, types 1, 2, and 3 macular neovascularization and polypoidal choroidal vasculopathy were present in 27.1%, 17.6%, 18.8%, and 36.5%, respectively. TAE and PRN regimens were used in 43.5% and 56.5% of patients, respectively. At baseline, the PRN group was older and had worse best-corrected visual acuity (BCVA), greater central retinal thickness, and more intraretinal fluid than the TAE group. In the TAE group, the mean number of injections was 7.6, BCVA improved significantly, and all retinal fluid rates decreased. In the PRN group, the mean number of injections was 3.9, BCVA remained unchanged, and the rates of macular fibrosis and atrophy increased. No serious adverse events were observed in either group. Anti-VEGF therapy was safe for patients aged ? 85 years with nAMD, and the TAE regimen effectively improved BCVA in this population. BCVA remained unchanged in the PRN-treated patients, with baseline disease severity and/or undertreatment potentially influencing the outcomes. en-copyright= kn-copyright= en-aut-name=OuchiChihiro en-aut-sei=Ouchi en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Morizane HosokawaMio en-aut-sei=Morizane Hosokawa en-aut-mei=Mio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=ShiodeYusuke en-aut-sei=Shiode en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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=7 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=anti-vascular endothelial growth factor therapy kn-keyword=anti-vascular endothelial growth factor therapy en-keyword=neovascular age-related macular degeneration kn-keyword=neovascular age-related macular degeneration en-keyword=age kn-keyword=age en-keyword=treat-and-extend kn-keyword=treat-and-extend en-keyword=pro re nata kn-keyword=pro re nata END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=11 article-no= start-page=1178 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251030 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sensory Modality-Dependent Interplay Between Updating and Inhibition Under Increased Working Memory Load: An ERP Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Working memory (WM) performance relies on the coordination of updating and inhibition functions within the central executive system. However, their interaction under varying cognitive loads, particularly across sensory modalities, remains unclear. Methods: This study examined how sensory modality modulates flanker interference under increasing WM loads. Twenty-two participants performed a visual n-back task at three load levels (1-, 2-, and 3-back) while ignoring visual (within-modality) or auditory (cross-modality) flankers. Results: Behaviorally, increased WM load (2- and 3-back) led to reduced accuracy (AC) and prolonged reaction times (RTs) in both conditions. In addition, flanker interference was observed under the 2-back condition in both the visual within-modality (VM) and audiovisual cross-modality (AVM) tasks. However, performance impairment emerged at a lower load (2-back) in the VM condition, whereas in the AVM condition, it only emerged at the highest load (3-back). Significant performance impairment in the AVM condition occurred at higher WM loads, suggesting that greater WM load is required to trigger interference. Event-related potential (ERP) results showed that N200 amplitudes increased significantly for incongruent flankers under the highest WM load (3-back) in the visual within-modality condition, reflecting greater inhibitory demands. In the cross-modality condition, enhanced N200 was not observed across all loads and even reversed at low load (1-back). Moreover, the results also showed that P300 amplitude increased with load in the within-modality condition but decreased in the cross-modality condition. Conclusions: These results demonstrated that the interaction between updating and inhibition is shaped by both WM load and sensory modality, further supporting a sensory modality-specific resource allocation mechanism. The cross-modality configurations may enable more efficient distribution of cognitive resources under high load, reducing interference between concurrent executive demands. en-copyright= kn-copyright= en-aut-name=LuoYuxi en-aut-sei=Luo en-aut-mei=Yuxi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GuoAo en-aut-sei=Guo en-aut-mei=Ao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WuJinglong en-aut-sei=Wu en-aut-mei=Jinglong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YangJiajia en-aut-sei=Yang en-aut-mei=Jiajia 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=Department of Psychology, Institute of Education, China West Normal University kn-affil= affil-num=3 en-affil=Faculty of Biomedical Engineering, Shenzhen University of Advanced Technology kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=workingmemory load kn-keyword=workingmemory load en-keyword=attentional resource allocation kn-keyword=attentional resource allocation en-keyword=modality-specific interference kn-keyword=modality-specific interference en-keyword=inhibitory control kn-keyword=inhibitory control en-keyword=executive function kn-keyword=executive function en-keyword=sensory modality kn-keyword=sensory modality END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue= article-no= start-page=1599114 end-page= 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=Effects of visual spatial frequency on audiovisual interaction: an event-related potential study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Spatial frequency is a fundamental characteristic of visual signals that modulates the audiovisual integration behavior, but the neural mechanisms underlying spatial frequency are not well established. In the present study, the high temporal resolution of event-related potentials was used to investigate how visual spatial frequency modulates audiovisual integration. A visual orientation discrimination task was used, and the spatial frequency of visual stimuli was manipulated under three conditions. Results showed that the influence of visual spatial frequency on audiovisual integration is a dynamic process. The earliest audiovisual integration occurred over the left temporal-occipital regions in the early sensory stage (60?90?ms) for high spatial frequency conditions but was absent for low and middle spatial frequency conditions. In addition, audiovisual integration over fronto-central regions was delayed as spatial frequency increased (from 230?260?ms to 260?320?ms). The integration effect was also observed over parietal and occipital regions at 350?380?ms, and its strength gradually decreased at higher spatial frequencies. These discrepancies in the temporal and spatial distributions of audiovisual integration imply that the role of spatial frequency varies between early sensory and late cognitive stages. The findings of this study offer the first neural demonstration that spatial frequency modulates audiovisual integration, thus providing a basis for studying complex multisensory integration, especially in semantic and emotional domains. en-copyright= kn-copyright= en-aut-name=WuFengxia en-aut-sei=Wu en-aut-mei=Fengxia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=RenYanna en-aut-sei=Ren en-aut-mei=Yanna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaoTengfei en-aut-sei=Hao en-aut-mei=Tengfei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YangJingjing en-aut-sei=Yang en-aut-mei=Jingjing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WuQiong en-aut-sei=Wu en-aut-mei=Qiong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YangJiajia en-aut-sei=Yang en-aut-mei=Jiajia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WangMeng en-aut-sei=Wang en-aut-mei=Meng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=School of Artificial Intelligence, Changchun University of Science and Technology kn-affil= affil-num=2 en-affil=Department of Psychology, College of Humanities and Management, Guizhou University of Traditional Chinese Medicine kn-affil= affil-num=3 en-affil=School of Artificial Intelligence, Changchun University of Science and Technology kn-affil= affil-num=4 en-affil=School of Artificial Intelligence, Changchun University of Science and Technology kn-affil= affil-num=5 en-affil=Department of Psychology, Suzhou University of Science and Technology kn-affil= affil-num=6 en-affil=Cognitive Neuroscience Laboratory, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=School of Artificial Intelligence, Changchun University of Science and Technology kn-affil= en-keyword=spatial frequency kn-keyword=spatial frequency en-keyword=visual orientation discrimination kn-keyword=visual orientation discrimination en-keyword=audiovisual integration kn-keyword=audiovisual integration en-keyword=early sensory stage kn-keyword=early sensory stage en-keyword=late cognitive stage kn-keyword=late cognitive stage en-keyword=event-related potentials kn-keyword=event-related potentials END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=2 article-no= start-page=101482 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Amelioration of Cd-induced bone deterioration by orally administered calcium phosphate en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cadmium (Cd) is a heavy metal that accumulates in the body, primarily through daily grain intake, and has a high affinity for bone, leading to skeletal diseases such as osteomalacia and fractures. Hydroxyapatite (HAp), a major bone mineral component, is highly pH-sensitive and is known to incorporate Cd, as observed in studies of Itai-itai disease. Based on these findings, we hypothesized that HAp could serve as an effective oral detoxification material for heavy metals. This study investigated the efficacy of orally administered HAp in inhibiting Cd-induced changes in bone physical and chemical properties, comparing its effects to those of activated charcoal (AC), a common detoxifying agent. Six-week-old male ICR mice were exposed to cadmium via drinking water containing CdCl2 and subsequently given diets containing either HAp or AC for four weeks. Three-point bending tests, micro-CT analysis, and histological observations of the femurs demonstrated that mice receiving HAp exhibited improved mechanical strength and enhanced bone quality protection compared to the control and other Cd-treated groups. Activated charcoal also contributed to bone quality improvement at low concentrations, but its effect diminished at high concentrations. These results suggest that the oral administration of HAp may be a promising therapeutic strategy for suppressing cadmium-induced osteomalacia. en-copyright= kn-copyright= en-aut-name=SungPing-chin en-aut-sei=Sung en-aut-mei=Ping-chin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BikharudinAhmad en-aut-sei=Bikharudin en-aut-mei=Ahmad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkadaMasahiro en-aut-sei=Okada en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MusaRanda en-aut-sei=Musa en-aut-mei=Randa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UchidaKenta en-aut-sei=Uchida en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtakaAkihisa en-aut-sei=Otaka en-aut-mei=Akihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsusakaTadaaki en-aut-sei=Matsusaka en-aut-mei=Tadaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsugakiAira en-aut-sei=Matsugaki en-aut-mei=Aira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakanoTakayoshi en-aut-sei=Nakano en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsumotoTakuya en-aut-sei=Matsumoto en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Division of Materials and Manufacturing Science, Graduate School of Engineering, Osaka University kn-affil= affil-num=8 en-affil=Division of Materials and Manufacturing Science, Graduate School of Engineering, Osaka University kn-affil= affil-num=9 en-affil=Division of Materials and Manufacturing Science, Graduate School of Engineering, Osaka University kn-affil= affil-num=10 en-affil=Department of Biomaterials, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Cadmium kn-keyword=Cadmium en-keyword=Bone deterioration kn-keyword=Bone deterioration en-keyword=Calcium phosphate kn-keyword=Calcium phosphate en-keyword=Bone quality kn-keyword=Bone quality END start-ver=1.4 cd-journal=joma no-vol=163 cd-vols= no-issue=22 article-no= start-page=224312 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fourier-transform infrared spectroscopy of hydrogen fluoride dimers in solid parahydrogen en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigate the Fourier-transform infrared spectra of hydrogen fluoride dimers in solid parahydrogen, the detailed analysis of which has remained unexplored. We propose a plausible analysis based on concentration dependence, light polarization, annealing, and time evolution. The absorption lines exhibited multiple peaks, with intensity ratios significantly altered by annealing and by time evolution at a constant temperature. The spectral patterns and isotopic effects suggest that the dimers do not rotate freely in solid parahydrogen, while multiple peaks arise from different stable structures, including single and double substitution sites. Unlike in the gas phase and helium droplets, no tunneling splitting was observed. The broad ν1 band suggests that some dimer structures may exhibit axial rotation. Spectral changes due to annealing likely result from site conversion, while observed IR-induced changes indicate preferential dissociation of dimers in double substitution sites. These findings still remain tentative, necessitating further experimental and theoretical studies. en-copyright= kn-copyright= en-aut-name=MiyamotoYuki en-aut-sei=Miyamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OoeHiroki en-aut-sei=Ooe en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KumaSusumu en-aut-sei=Kuma en-aut-mei=Susumu 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=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Physics, Rikkyo University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=18 article-no= start-page=9127 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250918 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Interaction Between Thyroid Hormones and Bone Morphogenetic Proteins in the Regulation of Steroidogenesis by Granulosa Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Thyroid hormones are fundamental regulators of cellular differentiation, development, and metabolism. Their receptors are expressed in reproductive tissues, including the ovary, and dysregulation of thyroid hormone homeostasis has been associated with menstrual disturbances, infertility, and adverse pregnancy outcomes. Bone morphogenetic protein (BMP) ligands and their receptors are functionally involved in gonadotropin-induced ovarian steroidogenesis in an autocrine or paracrine manner. In this study, we examined the effects of thyroid hormones on steroidogenesis and their interplay with BMP signaling by using human granulosa-like KGN cells and primary rat granulosa cells (GCs). In KGN cells, triiodothyronine (T3) enhanced forskolin-induced expression of key steroidogenic enzymes involved in both estradiol biosynthesis and progesterone synthesis/metabolism, whereas thyroxine (T4) exerted minimal effects. In rat GCs, T3 treatment increased follicle-stimulating hormone (FSH)-stimulated estradiol production without altering progesterone output. T3 pretreatment attenuated BMP-6-induced phosphorylation of Smad1/5/9 in KGN cells, accompanied by upregulation of inhibitory Smad6 and downregulation of the BMP type II receptor. Conversely, BMP-6 stimulation elevated thyroid hormone receptor β expression, indicating reciprocal regulatory interactions between thyroid hormone and BMP pathways. Collectively, these findings suggest that thyroid hormones modulate steroidogenesis, at least in part, through suppression of endogenous BMP-6 signaling in granulosa cells. en-copyright= kn-copyright= en-aut-name=MotohashiKanon en-aut-sei=Motohashi en-aut-mei=Kanon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SoejimaYoshiaki en-aut-sei=Soejima en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamamotoKoichiro en-aut-sei=Yamamoto en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IwataNahoko en-aut-sei=Iwata en-aut-mei=Nahoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SuyamaAtsuhito en-aut-sei=Suyama en-aut-mei=Atsuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=bone morphogenetic protein (BMP) kn-keyword=bone morphogenetic protein (BMP) en-keyword=thyroid hormone kn-keyword=thyroid hormone en-keyword=steroidogenesis kn-keyword=steroidogenesis en-keyword=ovary kn-keyword=ovary END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=4 article-no= start-page=104195 end-page= 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=Factors affecting the development of hypokalemia during apheresis in healthy donors en-subtitle= kn-subtitle= en-abstract= kn-abstract=Despite being generally safe, apheresis for peripheral blood stem cell collection potentially disrupts electrolyte balance owing to the use of citric acid as an anticoagulant. As prior research has primarily studied hypocalcemia, information on the kinetics of potassium levels during apheresis in healthy donors is scarce. We investigated the fluctuation in potassium levels during apheresis and the risk factors for hypokalemia. This subanalysis used data from an open-label, randomized controlled trial of “oral calcium supplementation versus placebo in mitigating citrate toxicity” conducted between January 2021 and July 2022, at Okayama University Hospital. Potassium levels were significantly reduced after 5-day granulocyte colony-stimulating factor (G-CSF) administration (p??15?% reduction in potassium levels from baseline was associated with age and the acid citrate dextrose solution A (ACD-A) volume in univariate analysis. In the multivariable analysis, both factors were associated (hazard ratio [HR], 11.60; 95?% confidence interval [CI], 1.60?83.70; p?=?0.02 and HR, 17.50; 95?% CI, 1.07?136.00; p?=?0.04). In conclusion, G-CSF administration and apheresis ultimately induced hypokalemia in two-thirds of the donors. Older age and higher ACD-A volume may affect potassium levels during apheresis in healthy donors. 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=FujiiKeiko en-aut-sei=Fujii en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=AbeMasaya en-aut-sei=Abe en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FukumiTakuya en-aut-sei=Fukumi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IkeuchiKazuhiro en-aut-sei=Ikeuchi en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Division of Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= en-keyword=Allogeneic kn-keyword=Allogeneic en-keyword=Peripheral blood stem cells kn-keyword=Peripheral blood stem cells en-keyword=Hypokalemia kn-keyword=Hypokalemia en-keyword=Acid citrate dextrose solution A kn-keyword=Acid citrate dextrose solution A en-keyword=Healthy donors kn-keyword=Healthy donors END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=14 article-no= start-page=4918 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250711 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Symptomatic Trends and Time to Recovery for Long COVID Patients Infected During the Omicron Phase en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Since the pathophysiology of long COVID is not yet fully understood, there are no specific methods for its treatment; however, its individual symptoms can currently be treated. Long COVID is characterized by symptoms that persist at least 2 to 3 months after contracting COVID-19, although it is difficult to predict how long such symptoms may persist. Methods: In the present study, 774 patients who first visited our outpatient clinic during the Omicron period from February 2022 to October 2024 were divided into two groups: the early recovery (ER) group (370 cases; 47.8%), who recovered in less than 180 days (median 33 days), and the persistent-symptom (PS) group (404 cases; 52.2%), who had symptoms that persisted for more than 180 days (median 437 days). The differences in clinical characteristics between these two groups were evaluated. Results: Although the median age of the two groups did not significantly differ (40 and 42 in ER and PS groups, respectively), the ratio of female patients was significantly higher in the PS group than the ER group (59.4% vs. 47.3%). There were no significant differences between the two groups in terms of the period after infection, habits, BMI, severity of COVID-19, and vaccination history. Notably, at the first visit, female patients in the PS group had a significantly higher rate of complaints of fatigue, insomnia, memory disturbance, and paresthesia, while male patients in the PS group showed significantly higher rates of fatigue and headache complaints. Patients with more than three symptoms at the first visit were predominant in the PS groups in both genders. Notably, one to two symptoms were predominant in the male ER group, while two to three symptoms were mostly reported in the female PS group. Moreover, the patients in the PS group had significantly higher scores for physical and mental fatigue and for depressive symptoms. Conclusions: Collectively, these results suggest that long-lasting long COVID is related to the number of symptoms and presents gender-dependent differences. en-copyright= kn-copyright= en-aut-name=AkiyamaHiroshi en-aut-sei=Akiyama en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=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=MatsudaYui en-aut-sei=Matsuda en-aut-mei=Yui 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=TokumasuKazuki en-aut-sei=Tokumasu en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 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=9 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=10 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=11 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=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University 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= en-keyword=fatigue kn-keyword=fatigue en-keyword=headache kn-keyword=headache en-keyword=insomnia kn-keyword=insomnia en-keyword=long COVID kn-keyword=long COVID en-keyword=Omicron variants kn-keyword=Omicron variants en-keyword=recovery kn-keyword=recovery END start-ver=1.4 cd-journal=joma no-vol=140 cd-vols= no-issue= article-no= start-page=105684 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Improvements of lateral penumbra at various depth regions in proton pencil beam scanning with a multileaf collimator: Dose verifications and plan comparisons en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: In scanned proton therapy, the current consensus is that the effective range of the collimator’s contribution to lateral penumbra improvement is up to approximately 150?mm depth. We characterized the penumbra variations for scanned proton beams with or without a new type of multileaf collimator (MLC) under various air gaps, depth, and with or without range shifter (RS).
Methods: Eighty-six uniform dose plans were created (38 RS-negative and 48 RS-positive plans) for nine box targets of 60?×?60?×?54?mm3 at 0?280?mm depths in water. They were created with or without MLC, with 50?300?mm air gaps. The penumbra and average doses of MLC-positive and MLC-negative plans at the organs at risk (OAR) region of each box plan were compared. Besides, several plan doses were validated by measurements with penumbra (with an average of 80?20?% dose point widths for both side profiles) differences and 2D gamma analysis.
Results: The MLC-positive plans reduced the penumbra and mean OAR doses by 1.0?5.1 mm and 3.3?13.5?%, respectively, compared to MLC-negative plans even at?>150?mm depths. The penumbra differences in measurements were <±1.5?mm for all plans. The mean gamma scores at 2?%/2 mm were 97.9?±?2.3?% and 97.4?±?3.1?% for the MLC-negative and MLC-positive plans, respectively.
Conclusions: The MLC-positive beams improved the penumbra and reduced the OAR dose in every depth region and air gap. We have shown that PBS with MLCs can be useful at more than 150?mm regions, depending on the machine. en-copyright= kn-copyright= en-aut-name=TominagaYuki en-aut-sei=Tominaga en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WakisakaYushi en-aut-sei=Wakisaka en-aut-mei=Yushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatoTakahiro en-aut-sei=Kato en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasuiKeisuke en-aut-sei=Yasui en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatoRyohei en-aut-sei=Kato en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IchiharaMasaya en-aut-sei=Ichihara en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TomidaMasashi en-aut-sei=Tomida en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SasakiMotoharu en-aut-sei=Sasaki en-aut-mei=Motoharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OitaMasataka en-aut-sei=Oita en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NishioTeiji en-aut-sei=Nishio en-aut-mei=Teiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Radiotherapy, Medical Co.

Here, we functionally characterized OsHAK4, a member of the clade IV HAK/KUP/KT transporter subfamily in rice. OsHAK4 was localized to the plasma membrane and exhibited influx transport activity for Na+, but not for K+. Analysis of organ- and growth stage-dependent expression patterns showed that very low expression levels of OsHAK4 were detected at the vegetative growth stage, but its high expression in uppermost node I, peduncle, and rachis was found at the reproductive stage. Immunostaining indicated OsHAK4 localization in the phloem region of node I, peduncle, and rachis. Knockout of OsHAK4 did not affect the growth and Na+ accumulation at the vegetative stage. However, at the reproductive stage, the hak4 mutants accumulated higher Na+ in the peduncle, rachis, husk, and brown rice compared to the wild-type rice. Element imaging revealed higher Na+ accumulation at the phloem region of the peduncle in the mutants. These results indicate that OsHAK4 plays a crucial role in retrieving Na+ from the phloem in the upper nodes, peduncle, and rachis, thereby preventing Na+ distribution to the grains at the reproductive stage of rice. en-copyright= kn-copyright= en-aut-name=CheJing en-aut-sei=Che en-aut-mei=Jing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamajiNaoki en-aut-sei=Yamaji en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WangShao Fei en-aut-sei=Wang en-aut-mei=Shao Fei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=XiaYue en-aut-sei=Xia en-aut-mei=Yue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YangShun Ying en-aut-sei=Yang en-aut-mei=Shun Ying kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuYan Hua en-aut-sei=Su en-aut-mei=Yan Hua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShenRen Fang en-aut-sei=Shen en-aut-mei=Ren Fang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MaJian Feng en-aut-sei=Ma en-aut-mei=Jian Feng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=Key Laboratory of Soil and Sustainable Agriculture, Institute of Soil Science, Chinese Academy of Sciences kn-affil= affil-num=4 en-affil=Key Laboratory of Soil and Sustainable Agriculture, Institute of Soil Science, Chinese Academy of Sciences kn-affil= affil-num=5 en-affil=Key Laboratory of Soil and Sustainable Agriculture, Institute of Soil Science, Chinese Academy of Sciences kn-affil= affil-num=6 en-affil=Key Laboratory of Soil and Sustainable Agriculture, Institute of Soil Science, Chinese Academy of Sciences kn-affil= affil-num=7 en-affil=Key Laboratory of Soil and Sustainable Agriculture, Institute of Soil Science, Chinese Academy of Sciences kn-affil= affil-num=8 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=rice kn-keyword=rice en-keyword=Oryza sativa kn-keyword=Oryza sativa en-keyword=salinity kn-keyword=salinity en-keyword=HAK transporter kn-keyword=HAK transporter en-keyword=phloem unloading kn-keyword=phloem unloading en-keyword=node kn-keyword=node END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=35 article-no= start-page=9749 end-page=9752 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250826 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis of a Pseudocytidine Nucleoside to Form a Stable and Selective Base Pair with Iso-guanosine in RNA en-subtitle= kn-subtitle= en-abstract= kn-abstract=Non-natural base pair formation provides insight into new functions of nucleic acids. Therefore, various artificial base pairs have been developed in both DNA and RNA. In this work, we successfully synthesized pseudocytidine from commercially available pseudouridine to form base pairs with isoguanine, also known as 2-OH-adenine, in RNA. Measurement of the melting temperature with the base pair incorporated at the center of a 13-mer RNA showed the highest value for the ψ-rC and iso-rG (2-OH-rA) base pair. This base pair formation exhibited a high melting temperature regardless of whether it was incorporated into the pyrimidine or purine strand, indicating that it can form a stable and selective duplex RNA. en-copyright= kn-copyright= en-aut-name=MiyaharaRyo en-aut-sei=Miyahara en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TaniguchiYosuke en-aut-sei=Taniguchi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Pharmaceutical Sciences, Kyushu University kn-affil= affil-num=2 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=3 article-no= start-page=e70101 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis of Oligodeoxynucleotide Containing Pseudo‐Deoxycytidine and Its Triphosphate Derivative en-subtitle= kn-subtitle= en-abstract= kn-abstract=This article describes a detailed synthetic protocol for the preparation of oligodeoxynucleotide (ODN) containing pseudo-deoxycytidine (ψdC) and its triphosphate derivative (ψdCTP). These molecules were synthesized as novel compounds that recognize iso-2'-deoxyguanosine (iso-dG) in DNA. Iso-dG is one of the tautomers of 2-hydroxy-2'-deoxyadenosine (2-OH-dA), which is known as an oxidatively damaged nucleobase, and its selective recognition in DNA is expected to play a very important role in the diagnosis and pathogenesis of diseases. The hydroxyl groups of the known glycal compound were protected with silyl groups, and then coupled with 5-iodouracil under Mizorogi-Heck reaction conditions, yielding ψdU after desilylation and diastereoselective reduction. The endocyclic amino group of ψdU was protected by the benzyl group. Subsequently, the carbonyl group at the 6-position of the nucleobase was activated and converted to an amino group through treatment with aqueous ammonia. The benzyl group was removed, and the exocyclic amino group was protected with a benzoyl group. On one hand, the silyl groups at the 3’ and 5’ positions were deprotected, converted into a phosphoramidite unit, and incorporated into an ODN. On the other hand, the hydroxyl group at the 5’ position was selectively deprotected and then directly converted into the triphosphate using Van Boom's reagent under acidic conditions. ? 2025 The Author(s).

Fe toxicity induces complex physiological and genetic responses, and due to this complexity, the knowledge of transcriptional regulatory mechanisms under Fe toxicity is very limited. Previous studies suggested that plant responses to excess Fe involve oxidative stress caused by reactive oxygen species (ROS), which itself causes transcriptional changes. We hypothesized that dissecting these complex responses could lead to the identification of a novel factor and conducted a comparative transcriptome analysis using roots of rice plants exposed to nutrient solutions containing 1 or 5?mM of hydrogen peroxide (a major form of ROS) or 300?mg?L?1 of Fe (as FeSO4). Genes induced by hydrogen peroxide overlapped with 62%, 49%, and 30% of Fe toxicity-upregulated genes at 3?h, 1?day, and 3?days following treatment initiation. Subsequent gene co-expression analyses classified genes into 21 groups with varying responsiveness to ROS and Fe toxicity. Genes in group 15 were specifically upregulated by Fe toxicity and overlapped significantly with aluminum (Al)-inducible genes and target genes of the Zn-finger transcription factor, ART1, which regulates Al response in rice roots. Additional experiments using the art1 knock-out mutant demonstrated that ART1 is crucial for upregulating genes such as STAR2 and FRDL4 in response to Fe toxicity. This study reveals the contribution of ART1-dependent regulatory pathways in rice roots under Fe toxicity. en-copyright= kn-copyright= en-aut-name=UedaYoshiaki en-aut-sei=Ueda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamajiNaoki en-aut-sei=Yamaji en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WissuwaMatthias en-aut-sei=Wissuwa en-aut-mei=Matthias kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Crop, Livestock and Environment Division, Japan International Research Center for Agricultural Sciences kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Crop, Livestock and Environment Division, Japan International Research Center for Agricultural Sciences kn-affil= en-keyword=ART1 kn-keyword=ART1 en-keyword=gene co-expression analysis kn-keyword=gene co-expression analysis en-keyword=iron toxicity kn-keyword=iron toxicity en-keyword=reactive oxygen species kn-keyword=reactive oxygen species en-keyword=rice kn-keyword=rice END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=8 article-no= start-page=1537 end-page=1544 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250528 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Phase-Ib dose-finding and pharmacokinetic trial of metformin combined with nivolumab for refractory/recurrent solid tumors en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Our previous findings showed that the addition of metformin to nivolumab resulted in remarkable tumor regression and increased the number of tumor-infiltrating T cells in mouse models. Therefore, we conducted a phase Ib study using combination therapy with nivolumab and metformin in patients with refractory/recurrent solid tumors.
Methods This study consisted of two parts: 1, evaluating the maximum tolerated dose (MTD), safety, pharmacokinetics in solid tumors, and 2, principally investigating the safety at the recommended dose limited to thoracic and pancreatic cancers. Metformin and nivolumab were administered orally at doses of 750?2,250 mg/day and biweekly at a fixed intravenous dose of 3 mg/kg, respectively. Dose-limiting toxicity was evaluated within the first 4 weeks. Both metformin and nivolumab were continued until disease progression or discontinued because of toxicity.
Results In total, 17 and 24 patients were enrolled in parts 1 and 2, respectively. One patient experienced increased pancreatic enzyme levels (grade 4) and lactic acidosis (grade 3). No Grade 5 adverse events were observed. MTD was not reached up to 2,250 mg/day of metformin, 2,250 mg/day was selected for part 2. An objective response was observed in 4 of 41 patients. One-year progression-free and overall survival rates were 9.8% and 56.8%, respectively. Two patients remained alive without disease progression for more than three years.
Conclusions Nivolumab and metformin combination therapy was well-tolerated and showed preliminary signals of efficacy in a subset of patients. Further verification of the underlying mechanism in cases where treatment is effective is required.

Here, we show that using water-soluble Ti complexes as precursors in the microwave-assisted hydrothermal synthesis of the oxyhalide photocatalyst Pb2Ti2O5.4F1.2 (PTOF) resulted in the production of nanoparticulate PTOF. The primary particle size of the synthesized PTOF ranged from several tens of nanometers to several hundreds of nanometers. Using Ti-citric acid or Ti-tartaric acid complexes as precursors, the PTOF was formed as mesoporous aggregates, compared with a bulky analogue (0.5?1 μm) prepared using a TiCl4 precursor. The PTOF prepared from Ti-citric acid complex had a particle size of 50?100 nm and showed a one-order-of-magnitude greater activity for H2 evolution from an aqueous ethylenediaminetetraacetic acid solution with the aid of a Rh cocatalyst. An apparent quantum yield (AQY) of 15.4 ± 1.0% at 420 nm, which is the highest among the reported oxyhalide photocatalysts, was achieved under optimal conditions. Although excess particle size reduction of PTOF lowered the H2 evolution activity, the PTOF with the smallest possible primary particle size of 15?30 nm, prepared from Ti-tartaric acid complex, showed the highest activity toward the selective reduction of CO2 into formate in a nonaqueous environment when combined with a binuclear Ru(II) complex. The CO2 reduction AQY was 10.4 ± 1.8% at 420 nm, a record-high value among metal-complex/semiconductor binary hybrid photocatalysts. This study highlights the importance of morphological control of oxyhalides for realizing their full potential as photocatalysts for artificial photosynthesis. en-copyright= kn-copyright= en-aut-name=UekiHiroto en-aut-sei=Ueki en-aut-mei=Hiroto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaToshiya en-aut-sei=Tanaka en-aut-mei=Toshiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AnabukiShuji en-aut-sei=Anabuki en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakadaRyuichi en-aut-sei=Nakada en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkazakiMegumi en-aut-sei=Okazaki en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AiharaKenta en-aut-sei=Aihara en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HattoriMasashi en-aut-sei=Hattori en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IshiwariFumitaka en-aut-sei=Ishiwari en-aut-mei=Fumitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HarukiRie en-aut-sei=Haruki en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NozawaShunsuke en-aut-sei=Nozawa en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YokoiToshiyuki en-aut-sei=Yokoi en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HaraMichikazu en-aut-sei=Hara en-aut-mei=Michikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=IshitaniOsamu en-aut-sei=Ishitani en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=SaekiAkinori en-aut-sei=Saeki en-aut-mei=Akinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=YamakataAkira en-aut-sei=Yamakata en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=MaedaKazuhiko en-aut-sei=Maeda en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Chemistry, School of Science, Institute of Science Tokyo kn-affil= affil-num=2 en-affil=Department of Chemistry, School of Science, Institute of Science Tokyo kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Chemistry, School of Science, Institute of Science Tokyo kn-affil= affil-num=5 en-affil=Department of Chemistry, School of Science, Institute of Science Tokyo kn-affil= affil-num=6 en-affil=Department of Chemistry, School of Science, Institute of Science Tokyo kn-affil= affil-num=7 en-affil=Materials and Structures Laboratory, Institute of Integrated Research, Institute of Science Tokyo kn-affil= affil-num=8 en-affil=Department of Applied Chemistry, Graduate School of Engineering, Osaka University kn-affil= affil-num=9 en-affil=Institute of Materials Structure Science, High Energy Accelerator Research Organization kn-affil= affil-num=10 en-affil=Institute of Materials Structure Science, High Energy Accelerator Research Organization kn-affil= affil-num=11 en-affil=Nanospace Catalysis Unit, Institute of Integrated Research, Institute of Science Tokyo kn-affil= affil-num=12 en-affil=Materials and Structures Laboratory, Institute of Integrated Research, Institute of Science Tokyo kn-affil= affil-num=13 en-affil=Department of Chemistry, Graduate School of Advanced Science and Engineering, Hiroshima University kn-affil= affil-num=14 en-affil=Department of Applied Chemistry, Graduate School of Engineering, Osaka University kn-affil= affil-num=15 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=16 en-affil=Department of Chemistry, School of Science, Institute of Science Tokyo kn-affil= en-keyword=artificial photosynthesis kn-keyword=artificial photosynthesis en-keyword=solar fuels kn-keyword=solar fuels en-keyword=mixed-anion compounds kn-keyword=mixed-anion compounds en-keyword=oxyfluorides kn-keyword=oxyfluorides en-keyword=water splitting kn-keyword=water splitting END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=6 article-no= start-page=3541 end-page=3552 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250311 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Metal-Cation Doping on Photocatalytic H2 Evolution Activity of Layered Perovskite Oxynitride K2LaTa2O6N en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aliovalent cation doping into a heterogeneous photocatalyst affects several of its physicochemical properties, including its morphological characteristics, optical absorption behavior, and charge carrier dynamics, causing a drastic change in its photocatalytic activity. In the present work, we investigated the effects of aliovalent cation doping on the visible-light H2-evolution photocatalytic activity of the Ruddlesden?Popper layered perovskite oxynitride K2LaTa2O6N. The photocatalytic activity toward H2 evolution from an aqueous NaI solution was found to be enhanced by an increase in the specific surface area of the K2LaTa2O6N photocatalyst, which could be realized upon doping with lower-valence cations (e.g., Mg2+, Al3+, and Ga3+). Among the dopants examined at 1 mol % doping, Ga resulted in the highest activity. The activity of the Ga-doped specimen was further improved with increasing Ga concentration, where the maximal activity was obtained at 10 mol %, corresponding to an apparent quantum yield of 2.7 ± 0.4% at 420 nm from aqueous methanol. This number is the highest reported for a layered oxynitride photocatalyst. In the Ga-doped K2LaTa2O6N, a trade-off was observed between the Ga concentration and the photocatalytic activity. Although doping with Ga reduced the particle size of K2LaTa2O6N and suppressed undesirable charge recombination, it led to an enlarged bandgap, unsuitable for visible-light absorption. en-copyright=

retrospective analysis focusing on long-term anal preservation en-subtitle= kn-subtitle= en-abstract= kn-abstract=To investigate the safety and efficacy of FOLFOXIRI as neoadjuvant chemotherapy (NAC) for locally advanced rectal cancer (LARC). The outcomes of preoperative and perioperative treatments, as well as long-term outcomes, were retrospectively compared between 26 patients who underwent FOLFOXIRI as NAC for LARC with cT3?4 and/or N+ at our institute between 2015 and 2022, and 31 patients with LARC who underwent neoadjuvant chemoradiotherapy (CAPOX-RT) at our institute between 2011 and 2022. Grade 3 or higher adverse events due to neoadjuvant treatment were significantly more common in the FOLFOXIRI group (11 cases, 42.3 %) than in the CAPOX-RT group (3 cases, 9.7 %), and most of these were neutropenia. Based on the postoperative pathological findings, the complete response rate was significantly lower in the FOLFOXIRI group (1 case, 3.8 %) than in the CAPOX-RT group (7 cases, 22.6 %), but there were no significant differences in the R0 resection rate, survival rate, or relapse-free survival rate. In the CAPOX-RT group, 17 patients (54.8 %) had anal preservation, and during the observation period, 4 patients required stoma construction due to loss of anal function in the late stage. In contrast, in the FOLFOXIRI group, there were no cases of loss of anal function among the 20 patients (76.9 %) who had anal preservation. FOLFOXIRI as NAC requires caution regarding hematological toxicity, but it can be an effective treatment option for patients with LARC who wish to preserve their anus. en-copyright= kn-copyright= en-aut-name=ShojiRyohei en-aut-sei=Shoji en-aut-mei=Ryohei 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=MatsumiYuki en-aut-sei=Matsumi en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=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=ShigeyasuKunitoshi en-aut-sei=Shigeyasu en-aut-mei=Kunitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=MoriYoshiko en-aut-sei=Mori en-aut-mei=Yoshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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=10 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Digestive Tract and General Surgery, Saitama Medical Center, Saitama Medical University kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of 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=Neoadjuvant chemotherapy kn-keyword=Neoadjuvant chemotherapy en-keyword=FOLFOXIRI kn-keyword=FOLFOXIRI en-keyword=Late pelvic toxicity kn-keyword=Late pelvic toxicity END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=3 article-no= start-page=e70091 end-page= 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=Autoclaved lightweight aerated concrete suppressed N2O and CO2 emissions from paddy soil en-subtitle= kn-subtitle= en-abstract= kn-abstract=Autoclaved lightweight aerated concrete (AAC), a construction waste that is utilized as a soil amendment, can influence terrestrial carbon dioxide (CO2) emissions. Still, no evidence exists regarding its impact on the emission of nitrous oxide (N2O), which has a higher global warming potential. This study examined effects of AAC on CO2 and N2O emissions from paddy soil under compacted and non-compacted conditions, under 60% and 100% water-holding capacity (WHC). Samples were incubated in glass vials (25°C) for 21 days. Emissions of CO2 and N2O were measured on days 0, 1, 3, 7, 14, and 21 using gas chromatography. The results revealed that AAC significantly (p < 0.05) lowered N2O emission rate during the whole period of incubation, while it suppressed CO2 emission rate only at the early stages (?7 days) of incubation. In compacted soil, the emissions of CO2 were significantly lower, while N2O was significantly higher than that in non-compacted soil, showing the influence of soil physical conditions. The emissions of CO2 and N2O were significantly lower at 100% WHC than those at 60% WHC. AAC suppressed both CO2 and N2O emissions under both compaction and WHC levels. The results confirm that AAC supports suppressing terrestrial emission of both CO2 and N2O, indicating that AAC has a potential as a sustainable soil amendment that enhances the climate change resilience. en-copyright= kn-copyright= en-aut-name=RathnayakeNagoda R.

Using a quantum mechanical/molecular mechanical approach, we identified the structural nature of this unique water cluster. The triangular shape is best reproduced when all three water molecules are neutral H2O with protonated Glu187 and deprotonated Glu197. Attempts to place H3O+ at any of these water molecules result in spontaneous proton transfer to one of the acidic residues and significant distortion from the crystal structure. The plane defined by the triangular water cluster extends into the guanidinium plane of Arg71, with both aligned along the W413...W419 axis. This extended plane lies nearly perpendicular to a five-membered, ring-like H-bond network involving two carboxyl oxygen atoms from Glu187 and one from Glu197. The resulting bipartite planar architecture, defined by the water triangle, Arg71, and the Glu187/Glu197 network may reflect the exceptional thermal stability in RxR. en-copyright= kn-copyright= en-aut-name=NojiTomoyasu en-aut-sei=Noji en-aut-mei=Tomoyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujimuraMasaki en-aut-sei=Tsujimura en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SaitoKeisuke en-aut-sei=Saito en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KojimaKeiichi en-aut-sei=Kojima en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SudoYuki en-aut-sei=Sudo en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IshikitaHiroshi en-aut-sei=Ishikita 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 Applied Chemistry, Graduate School of Engineering, The University of Tokyo kn-affil= affil-num=2 en-affil=Department of Advanced Interdisciplinary Studies, The University of Tokyo kn-affil= affil-num=3 en-affil=Department of Applied Chemistry, Graduate School of Engineering, The University of Tokyo kn-affil= affil-num=4 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Applied Chemistry, Graduate School of Engineering, The University of Tokyo kn-affil= en-keyword=microbial rhodopsin kn-keyword=microbial rhodopsin en-keyword=proton transfer pathway kn-keyword=proton transfer pathway en-keyword=H3O+ kn-keyword=H3O+ en-keyword=pKa kn-keyword=pKa en-keyword=proton release group kn-keyword=proton release group END start-ver=1.4 cd-journal=joma no-vol=187 cd-vols= no-issue= article-no= start-page=106403 end-page= 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=Nitrogen distribution and nitrogen isotope fractionation in synthetic 2:1 phyllosilicates under hydrothermal conditions at 200?°C and saturated vapor pressure en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study investigates nitrogen distribution and isotope fractionation within synthetic 2:1 phyllosilicates, simulating submarine hydrothermal environments at 200 °C and saturated vapor pressure. XRD and EDS results revealed the potential coexistence of multiple cations in the interlayer of synthetic 2:1 phyllosilicate, concurrently suggesting cation substitution in the tetrahedral and/or octahedral sheets. Meanwhile, the iron-enriched 25-5 sample exhibited restricted interlayer expansibility. NH4+ absorptions were identified in the NH4-stretching (3200?2800 cm?1) and NH4-bending (1450?1400 cm?1) regions, with wavenumber shifts indicating the influence of interlayer water removal. At pH 10.56, over 95% of nitrogen was released into the gas phase, while at pH 8.88, nitrogen proportions in the liquid and gas phases were comparable (average 48?49%). Experiments with iron at pH ?8.80 showed that the nitrogen proportion in the gas phase (average 28%) was more than twofold lower than that in the liquid phase (average 68%). Equilibrium isotope fractionation factors indicated discernible preference for heavier nitrogen isotopes in the solid phase (αsolid-liquid = 1.009?1.021 and αsolid-gas = 1.011?1.027). The αliquid-gas range for sample 25?2 was 1.001?1.008, while that for the iron-enriched composite 25?5 was 0.997?1.010. Our experimental studies have confirmed that, in the absence of exchange interactions with external substances possessing different nitrogen isotope ratios, nitrogen isotope fractionation between ammonium and ammonia, controlled by variations in temperature and pH during mineralization, plays a crucial role in the variation of nitrogen isotope ratios. Additionally, we confirmed that metal-amines influence nitrogen isotope fractionation by modulating ammonia gas emission. These findings enhance our understanding of nitrogen cycling across the gas, liquid, and solid phases in submarine hydrothermal systems. en-copyright= kn-copyright= en-aut-name=JoJaeguk en-aut-sei=Jo en-aut-mei=Jaeguk kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamanakaToshiro en-aut-sei=Yamanaka en-aut-mei=Toshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyoshiYouko en-aut-sei=Miyoshi en-aut-mei=Youko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuzukiMasaya en-aut-sei=Suzuki en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KuwaharaYoshihiro en-aut-sei=Kuwahara en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KadotaIsao en-aut-sei=Kadota en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ChibaHitoshi en-aut-sei=Chiba en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=LeeBum Han en-aut-sei=Lee en-aut-mei=Bum Han kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Geo-Resources and Environment, Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology (AIST) kn-affil= affil-num=4 en-affil=Research Institute for Geo-Resources and Environment, Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology (AIST) kn-affil= affil-num=5 en-affil=Department of Environmental Changes, Faculty of Social and Cultural Studies, Kyushu University kn-affil= affil-num=6 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Critical Minerals Research Center, Korea Institute of Geoscience & Mineral Resources (KIGAM) kn-affil= en-keyword=Synthetic 2:1 phyllosilicates kn-keyword=Synthetic 2:1 phyllosilicates en-keyword=Nitrogen distribution kn-keyword=Nitrogen distribution en-keyword=Nitrogen isotope fractionation kn-keyword=Nitrogen isotope fractionation en-keyword=Hydrothermal system kn-keyword=Hydrothermal system END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=1 article-no= start-page=e70052 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251214 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Japanese Adult Day Service Nurses' Bathing Decisions for Persons Requiring Long‐Term Care: A Focused Ethnography en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Adult day services in Japan operate under the Long-Term Care Insurance Law, and care is provided mainly by caregivers. However, because doctors are often not on site, nurses manage the health of the person requiring long-term care. Adult day services provide bathing and functional training; however, although Japanese-style bathing relieves fatigue and brings a sense of well-being, it also entails the risk of bathing accidents for those in need of care. To continue living at home, those in need of care who have difficulty bathing at home must be provided with safe bathing during adult day services and supported in returning home safely. Nurses are responsible for accurately assessing the health status of users and implementing safe bathing. This study aimed to identify how nurses working in adult day services make bathing decisions for home-dwelling persons requiring long-term care.
Method: Qualitative manifest and latent content analyses were performed using a focused ethnography.
Findings: Six themes were identified: ‘gather information to compare with baseline’, ‘make observations based on information from others to understand the big picture’, ‘give persons time to get in shape’, ‘consideration of life at home’, ‘determining the need for medical institutions’ and ‘devise ways to communicate to promote collaboration’.
Conclusions: Adult day service nurses' decisions about whether to bathe persons requiring care are characterised by their emphasis on information from others, consideration of the home living conditions of persons requiring care and their wishes regarding bathing. In addition, based on their observations, they determine the need for cooperation with medical institutions and communicate this information to family members and multiple professions. en-copyright= kn-copyright= en-aut-name=MiyoshiKanako en-aut-sei=Miyoshi en-aut-mei=Kanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoriKeiko en-aut-sei=Mori en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=adult day service kn-keyword=adult day service en-keyword=clinical judgement kn-keyword=clinical judgement en-keyword=community kn-keyword=community en-keyword=home care kn-keyword=home care en-keyword=multidisciplinary collaboration kn-keyword=multidisciplinary collaboration en-keyword=nurses kn-keyword=nurses en-keyword=persons requiring care kn-keyword=persons requiring care END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=18 article-no= start-page=5359 end-page=5365 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=Deoxygenative dual CO2 conversions: methylenation and switchable N-formylation/N-methylation of tryptamines en-subtitle= kn-subtitle= en-abstract= kn-abstract=The unprecedented one-pot synthesis of N-formyl/N-methyltryptolines from tryptamines was achieved via phenylsilane-assisted deoxygenative dual CO2 conversions. Two CO2 molecules acted as different synthons and were converted into methylene and N-formyl/N-methyl groups. The CO2 reduction step was catalyzed by a pentanuclear zinc complex at atmospheric pressure under solvent-free conditions. The N-formyl/N-methyl products could be switched by changing the amount of phenylsilane, and the amounts of in situ generated bis(silyl)acetals and silyl formates were key to the chemoselectivity. Methylenation, N-formylation, and N-methylation proceeded via the Pictet?Spengler reaction, amine?acid condensation, and the Eschweiler?Clarke reaction, respectively. The CO2 reduction with phenylsilane could also be applied to the one-pot three-step synthesis of spiro[oxindole-pyrrolidine]s. en-copyright= kn-copyright= en-aut-name=TakaishiKazuto en-aut-sei=Takaishi en-aut-mei=Kazuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorishitaHajime en-aut-sei=Morishita en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IwakiKosuke en-aut-sei=Iwaki en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EmaTadashi en-aut-sei=Ema en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END
