Flower opening time (FOT) critically affects the seed setting rate. In this study, we identified a gene, EARLY-MORNING FLOWERING 3 (EMF3), in which single-nucleotide substitutions strongly modulate FOT in rice in a semi-dominant manner, resulting in wide variation in FOT from earlier to later FOT than the wild-type. EMF3 knock-out mutants showed significantly reduced FOT synchrony and disrupted anther dehiscence, leading to fertilisation failure. EMF3 encodes a plasma membrane-localised polypeptide of 723 amino acids with an armadillo repeat fold and four transmembrane segments. Furthermore, EMF3 is specifically expressed in the anthers starting from nighttime on the day of flowering, with substantial impacts on the transcriptomes of both anther and lodicule, which suggested an exclusive role of EMF3 in flowering events. Modifying EMF3 alleles of O. sativa enabled the adjustment of FOT among Oryza species and subspecies, potentially facilitating cross-fertilisation by overcoming one of the major challenges of inter-specific hybridisation to exploit heterosis. Introducing the EMF3 alleles with the earlier FOT into popular rice cultivars resulted in flowering at an earlier time of day when the temperature was cooler, efficiently increasing seed setting rate under heat stress. This discovery unveils the novel mechanism of anther control of flower opening time through the EMF3 gene, while also enabling the use of EMF3 alleles in breeding strategies for efficient fertilisation for increasing hybrid rice seed production and mitigating future heat-stress damage at flowering. en-copyright= kn-copyright= en-aut-name=IshizakiTakuma en-aut-sei=Ishizaki

In domestic chickens, constitutively activating mutations such as the MC1R^E (E92K) allele cause melanistic phenotypes, demonstrating that persistent MC1R activation can drive generalized darkening. However, to our knowledge, no experimental study has directly demonstrated constitutive MC1R activation in wild birds exhibiting uniformly black plumage. We investigated the sequence and signaling properties of MC1R from the Large-billed Crow (Corvus macrorhynchos), a species with strongly eumelanin-dominant plumage. Crow MC1R exhibited elevated basal cAMP signaling and minimal responsiveness to α-melanocyte-stimulating hormone (α-MSH) in both stable Chinese hamster ovary (CHO-K1) cells and transient CRE-luciferase assays in HEK293T cells, demonstrating ligand-independent activation comparable to that observed in the melanizing chicken MC1R^E (E92K) allele. Comparative sequence analysis identified multiple substitutions conserved across Corvus species. Among these, E12K and E18K were functionally evaluated based on prior associations with melanism in other birds. Although E12K modestly increased basal signaling in chicken MC1R, E18K alone or in combination with E12K did not reproduce crow-level constitutive activity, and reciprocal substitutions in crow MC1R failed to abolish ligand-independent activation. These findings demonstrate that crow MC1R possesses constitutive activity and suggest that this phenotype reflects lineage-specific modifications rather than a single activating substitution. Our results provide experimental evidence that constitutive MC1R activation is a plausible molecular mechanism that may contribute to the black plumage in the Large-billed Crow, although a direct causal relationship remains to be established. en-copyright= kn-copyright= en-aut-name=NakanoSaya en-aut-sei=Nakano en-aut-mei=Saya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TashiroYuichi en-aut-sei=Tashiro en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukuchiHibiki en-aut-sei=Fukuchi en-aut-mei=Hibiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AizawaSayaka en-aut-sei=Aizawa en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakeuchiSakae en-aut-sei=Takeuchi en-aut-mei=Sakae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of 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 Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=MC1R kn-keyword=MC1R en-keyword=Constitutive activation kn-keyword=Constitutive activation en-keyword=Ligand-independent signaling kn-keyword=Ligand-independent signaling en-keyword=Melanism kn-keyword=Melanism en-keyword=Plumage coloration kn-keyword=Plumage coloration en-keyword=Corvus macrorhynchos kn-keyword=Corvus macrorhynchos END start-ver=1.4 cd-journal=joma no-vol=264 cd-vols= no-issue= article-no= start-page=128798 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202608 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Improving thermal stability of a microcavity emitter for utilization under atmospheric environment en-subtitle= kn-subtitle= en-abstract= kn-abstract=With the development of micro-fabrication technology, various metamaterials with controlled emission spectra have been proposed as thermal emitters. 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 Astronómico 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.

The expression of rhodopsin genes in R7 and R8 is highly coordinated through an instructive signal from R7 to R8. The activity of the homeodomain protein Defective proventriculus in R1 is also required to transmit this instructive signal, suggesting that cell–cell communication between R7, R1, and R8 is important to generate the pattern of Rh expression in R7/R8 (Rhodopsin coupling). As cell junctions play crucial roles in maintaining the structural and functional integrity of tissues, we tested whether cell junction proteins are involved in the interactions between photoreceptor cells. Here, we demonstrate that gap junction proteins innexin 2 and innexin 7 in accessory cells are necessary for transmitting signals from R7 to R8. In addition, Notch-mediated accessory cell development and Rhodopsin coupling in R7/R8 are highly correlated. Our results provide evidence that functional coupling of two different neurons, R7 and R8, is established through gap junction-mediated signaling from adjacent accessory cells. en-copyright= kn-copyright= en-aut-name=ZhangXuanshuo en-aut-sei=Zhang en-aut-mei=Xuanshuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShinjoRyoki en-aut-sei=Shinjo en-aut-mei=Ryoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KitamataManabu en-aut-sei=Kitamata en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OtsuneShinichi en-aut-sei=Otsune en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakagoshiHideki en-aut-sei=Nakagoshi en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Division of Biological Sciences, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Biological Sciences, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Division of Health Science, Advanced Comprehensive Research Organization, Teikyo University kn-affil= affil-num=4 en-affil=Division of Biological Sciences, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Division of Biological Sciences, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Drosophila kn-keyword=Drosophila en-keyword=Eye kn-keyword=Eye en-keyword=Gap junction kn-keyword=Gap junction en-keyword=Innexin kn-keyword=Innexin en-keyword=Opsin kn-keyword=Opsin END start-ver=1.4 cd-journal=joma no-vol=179 cd-vols= no-issue= article-no= start-page=156034 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202606 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Visible-light-induced photocatalytic intermolecular cyclization for synthesis of 2,2-diarylchromanes en-subtitle= kn-subtitle= en-abstract= kn-abstract=The photocatalytic cyclization of salicylaldehydes with 1,1-diarylalkenes for the synthesis of 2,2-diarylchromanes has been developed. The catalytic amount of Ir photocatalyst proceeds the cyclization to give the various 2,2-diaryl chromanes under irradiation with blue LEDs. The obtained 2,2-diarylchromanes exhibit noticeable free-radical-scavenging activities, which have been largely unexplored. Notably, the chromane can convert to 2,2-diaryl-2H-naphtho[1,2-b]pyran bearing strong electron withdrawing groups, which are found in various photochromic materials. Thus, the present reaction constitutes a promising tool for the synthesis of functional materials and biologically active compounds. en-copyright= kn-copyright= en-aut-name=KodakiSakura en-aut-sei=Kodaki en-aut-mei=Sakura kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KondoMomo en-aut-sei=Kondo en-aut-mei=Momo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MinatoJunta en-aut-sei=Minato en-aut-mei=Junta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ItakuraShoko en-aut-sei=Itakura en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakamuraHiroyoshi en-aut-sei=Takamura en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishikawaMakiya en-aut-sei=Nishikawa en-aut-mei=Makiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=KusamoriKosuke en-aut-sei=Kusamori en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaKenta en-aut-sei=Tanaka en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Biopharmaceutics, Faculty of Pharmaceutical Sciences, Tokyo University of Science kn-affil= affil-num=3 en-affil=Laboratory of Cellular Drug Discovery and Development, Faculty of Pharmaceutical Sciences, Tokyo University of Science kn-affil= affil-num=4 en-affil=Laboratory of Biopharmaceutics, Faculty of Pharmaceutical Sciences, Tokyo University of Science 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=Laboratory of Biopharmaceutics, Faculty of Pharmaceutical Sciences, Tokyo University of Science 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=Laboratory of Cellular Drug Discovery and Development, Faculty of Pharmaceutical Sciences, Tokyo University of Science kn-affil= affil-num=9 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=Chromane kn-keyword=Chromane en-keyword=Visible light kn-keyword=Visible light en-keyword=Photocatalysis kn-keyword=Photocatalysis en-keyword=Chromene kn-keyword=Chromene en-keyword=Free-radical-scavenging activity kn-keyword=Free-radical-scavenging activity 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=20260401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Triangulation in teaching probability: teaching materials for the theoretical foundations of probability in real-world applications en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper proposes using the concept of triangulation with probabilistic models as a means to enhance theoretical inversion for deepening students’ understanding of the nature of probability in real-world contexts. Triangulation refers to the combined application of multiple methodologies to investigate the same phenomenon, particularly in the social sciences. Theoretical inversion refers to a shift in focus from surprising outcomes to the theoretical foundations of probability. The paper introduces three types of problem-solving tasks designed to enhance one of four types of triangulations: theory triangulation. Theoretical inversion is expected to emerge through engaging in these tasks. The characteristics of the problems are as follows. Problem 1 promotes students to compare different probabilistic models of events under similar procedures. Problem 2 provides students with an opportunity to simplify an experiment by omitting steps that add no new information. Problem 3 enhances students’ ability to recognise how subtle differences in the experimental setup can affect the resulting probability. These tasks are designed to encourage students to view probabilistic reasoning as a form of modelling and to appreciate the importance of assumptions, definitions of elementary events, and clarity in procedural descriptions. en-copyright= kn-copyright= en-aut-name=UegataniYusuke en-aut-sei=Uegatani en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshibashiIppo en-aut-sei=Ishibashi en-aut-mei=Ippo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakotaAya en-aut-sei=Sakota en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Hiroshima University High School kn-affil= affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil= affil-num=3 en-affil=Hiroshima University High School kn-affil= en-keyword=Probability kn-keyword=Probability en-keyword=triangulation kn-keyword=triangulation en-keyword=mathematical modelling kn-keyword=mathematical modelling en-keyword=theoretical inversion kn-keyword=theoretical inversion END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=5 article-no= start-page=2308 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Aerobic Exercise Attenuates Epidermal Hyperplasia in an Obesity-Associated Psoriasiform Dermatitis Model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Obesity is an important risk factor for psoriasis, and clinical studies indicate that exercise interventions can improve disease severity. However, the mechanisms by which exercise influences psoriatic pathogenesis remain insufficiently understood. To investigate the effects of aerobic exercise on obesity-associated psoriasis, wild-type mice were fed a high-fat diet (HFD) for 7 weeks to induce obesity and subsequently underwent moderate-intensity treadmill running for 3 weeks. Psoriasiform dermatitis was induced by daily topical application of imiquimod (IMQ) to the skin for five consecutive days. HFD increased body weight, epididymal fat mass, and serum cholesterol. HFD-fed mice developed more severe IMQ-induced psoriatic skin changes compared with normal diet-fed mice. Treadmill exercise modestly reduced body weight gain and attenuated epidermal hyperplasia in HFD-fed mice. In contrast, inflammatory cytokine expression, including Tnfa, Il17a, and Il23a, showed modest increases in the skin of HFD-fed exercised mice, which did not parallel the improvement in epidermal hyperplasia. Overall, these findings indicate that while obesity exacerbates psoriasiform dermatitis, aerobic exercise ameliorates epidermal hyperplasia in obese mice without corresponding changes in inflammatory cytokine expression in the skin, suggesting that exercise may influence psoriatic skin changes through multiple metabolic and immunological pathways. en-copyright= kn-copyright= en-aut-name=MatsudaYoshihiro en-aut-sei=Matsuda en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorizaneShin en-aut-sei=Morizane en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakezakiDaiki en-aut-sei=Takezaki en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakamotoYuma en-aut-sei=Sakamoto en-aut-mei=Yuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BabaNobuyasu en-aut-sei=Baba en-aut-mei=Nobuyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IsekiMasanori en-aut-sei=Iseki en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawakamiYoshio en-aut-sei=Kawakami en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShiomiTatsushi en-aut-sei=Shiomi en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MukaiTomoyuki en-aut-sei=Mukai en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Immunology and Molecular Genetics, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of Immunology and Molecular Genetics, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of Immunology and Molecular Genetics, Kawasaki Medical School kn-affil= affil-num=7 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Pathology, Kawasaki Medical School kn-affil= affil-num=9 en-affil=Department of Immunology and Molecular Genetics, Kawasaki Medical School kn-affil= en-keyword=psoriasis kn-keyword=psoriasis en-keyword=obesity kn-keyword=obesity en-keyword=aerobic exercise kn-keyword=aerobic exercise en-keyword=imiquimod kn-keyword=imiquimod en-keyword=high-fat diet kn-keyword=high-fat diet END start-ver=1.4 cd-journal=joma no-vol=49 cd-vols= no-issue=2 article-no= start-page=364 end-page=370 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260221 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Functional Transport Properties of Human Zinc Transporter 1: Kinetics and pH-Dependency en-subtitle= kn-subtitle= en-abstract= kn-abstract=Intracellular zinc (Zn2+) homeostasis is essential for physiological and pathological processes and is strictly regulated by Zn2+ transporters. 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=25 cd-vols= no-issue= article-no= start-page=103265 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202606 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Peptide nanomicelles for NIR light-dependent siRNA delivery en-subtitle= kn-subtitle= en-abstract= kn-abstract=The peptide amphiphile PA8, derived from the GAVILRR peptide, was developed as a carrier for small interfering RNA (siRNA) delivery; however, its RNA interference (RNAi) efficacy was limited owing to predominant endocytotic uptake. In this study, the RNAi efficiency of PA8 nanomicelle/siRNA complexes was enhanced by modifying the nanomicelles with the photosensitizer DY750 and the tumor-homing peptide iRGD. The conjugation of DY750 to the nanomicelles facilitated endosomal escape of the nanomicelle/siRNA complexes, enabling the cytosolic release of siRNA. Additionally, the incorporation of iRGD improved RNAi delivery efficiency in the AsPC-1 pancreatic ductal adenocarcinoma cell line. PA8-DY750-iRGD nanomicelle complexes loaded with siRNA against polo-like kinase 1 (PLK1) achieved an 80% reduction in PLK1 mRNA levels in AsPC-1 cells and a moderate 28% knockdown in NCI-N87 gastric cancer cells. Notably, no RNAi effect was observed in noncancerous 1C3D3 pancreatic cells or HEK293T kidney cells, underscoring the selectivity of this system for AsPC-1 cells. These findings highlight the potential of PA8-DY750-iRGD nanomicelle complexes as a targeted therapeutic platform for specific cancers, particularly pancreatic cancer. en-copyright= kn-copyright= en-aut-name=HakimTaufik Fatwa Nur en-aut-sei=Hakim en-aut-mei=Taufik Fatwa Nur kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitamatsuMizuki en-aut-sei=Kitamatsu en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujimotoShoumu en-aut-sei=Fujimoto en-aut-mei=Shoumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeKazunori en-aut-sei=Watanabe en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OhtsukiTakashi en-aut-sei=Ohtsuki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Applied Chemistry, Kindai University kn-affil= affil-num=3 en-affil=Department of Applied Chemistry, Kindai University kn-affil= affil-num=4 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Peptide nanomicelles kn-keyword=Peptide nanomicelles en-keyword=siRNA kn-keyword=siRNA en-keyword=Near infrared light kn-keyword=Near infrared light en-keyword=Targeted delivery kn-keyword=Targeted delivery en-keyword=Photosensitizer kn-keyword=Photosensitizer END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=10464 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Liquid–liquid phase separation by caged coacervating peptides en-subtitle= kn-subtitle= en-abstract= kn-abstract=Liquid–liquid phase separation is an important biomolecular process in the formation of membraneless intracellular organelles that has inspired the development of artificial droplet systems. We developed caged coacervating peptides (CCPs) based on a histidine-rich squid beak protein sequence. The peptides were caged with a photodeprotectable (7-diethylaminocoumarin-4-yl)methoxycarbonyl group. The CCPs formed coacervates in the caged state and were partially dispersed upon blue-light irradiation. Photo-uncaging occurred rapidly, inducing coacervate dispersion. A mutant CCP with reduced π–π interactions exhibited efficient photo-dependent disassembly and enabled the encapsulation and release of a fluorescently labeled adenosine 5′-triphosphate (Bodipy-ATP) upon irradiation. These CCPs offer an efficient light-controlled approach for biomolecular encapsulation within coacervates and targeted drug delivery. en-copyright= kn-copyright= en-aut-name=BandoAkinari en-aut-sei=Bando en-aut-mei=Akinari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitamatsuMizuki en-aut-sei=Kitamatsu en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanazakiYuuki en-aut-sei=Kanazaki en-aut-mei=Yuuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TojoRika en-aut-sei=Tojo en-aut-mei=Rika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WatanabeKazunori en-aut-sei=Watanabe en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhtsukiTakashi en-aut-sei=Ohtsuki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Applied Chemistry, Kindai University kn-affil= affil-num=3 en-affil=Department of Applied Chemistry, Kindai University kn-affil= affil-num=4 en-affil=Department of Applied Chemistry, Kindai University kn-affil= affil-num=5 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Caged coacervating peptide kn-keyword=Caged coacervating peptide en-keyword=Liquid–liquid phase separation kn-keyword=Liquid–liquid phase separation en-keyword=Light kn-keyword=Light END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page=558 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=Evaluation of contact-active antibacterial properties of cetylpyridinium chloride–graphene oxide coatings on dental restorative and titanium surfaces: an in vitro study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective Biofilm formation on dental restorative materials and implant surfaces plays a central role in the development of dental caries, periodontal disease, and peri-implantitis. Durable antimicrobial surface treatments that inhibit bacterial adhesion and biofilm formation remain a significant unmet need in restorative and implant dentistry. Therefore, this study aimed to develop a composite coating combining cetylpyridinium chloride and graphene oxide, and to evaluate its durable antibacterial surface modification under in vitro conditions.
Methods A composite coating consisting of cetylpyridinium chloride and graphene oxide was prepared and applied to composite resin and titanium surfaces. Antibacterial activity against Streptococcus mutans and Porphyromonas gingivalis was evaluated using adenosine triphosphate assays and fluorescence-based live/dead staining. Coating retention after washing and air-drying was assessed by optical microscopy and Raman spectroscopy.
Results Cetylpyridinium chloride-graphene oxide-coated surfaces showed a significant reduction in bacterial viability compared with phosphate-buffered saline, ethanol, and cetylpyridinium chloride-only controls. Antibacterial effects were maintained after rinsing and air-drying on both composite resin and titanium surfaces. Raman spectroscopy confirmed the persistence of characteristic graphene oxide bands after washing, indicating stable retention of the coating on the material surfaces.
Conclusions Cetylpyridinium chloride–graphene oxide coatings demonstrate sustained surface-associated antibacterial activity against key cariogenic and periodontal pathogens and remain stably adhered to common dental restorative and implant materials after washing. These findings suggest that cetylpyridinium chloride–graphene oxide coatings may serve as a durable contact-active surface modification strategy to reduce biofilm formation associated with dental caries and peri-implantitis. 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=KamataHideyuki en-aut-sei=Kamata en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakamuraShin en-aut-sei=Nakamura en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Shinoda-ItoYuki en-aut-sei=Shinoda-Ito en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 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=9 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=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathophysiology - Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, 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= affil-num=7 en-affil=Department of Pathophysiology - Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=9 en-affil=Department of Pathophysiology - Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Wash-resistant antibacterial coating kn-keyword=Wash-resistant antibacterial coating en-keyword=Graphene oxide kn-keyword=Graphene oxide en-keyword=Cetylpyridinium chloride kn-keyword=Cetylpyridinium chloride en-keyword=Oral pathogenic bacteria kn-keyword=Oral pathogenic bacteria END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=4 article-no= start-page=760 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260327 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Role of Nitrate-Reducing Bacteria Isolated from Helicobacter pylori-Infected Individuals in Gastric Cancer Development en-subtitle= kn-subtitle= en-abstract= kn-abstract=Helicobacter pylori is a Gram-negative bacterium that inhabits the gastric mucosa, with a global prevalence in humans of approximately 40%. It is likely the cause of 90% of gastric cancer (GC) cases and thus considered the most prominent driver of GC development. However, during gastric mucosal atrophy, other bacteria such as nitrate-reducing bacteria (NRB) also proliferate. In this study, we isolated NRB from patients with gastritis and GC to examine their effects on the epithelial cell cycle and production of various cytokines in monocytic cell lines. Bacterial counts (excluding H. pylori and NRB) increased with the progression of gastric mucosal atrophy and were significantly higher in patients with GC. Gastric epithelial cell lines were stimulated with isolated NRB, and the proportion of cells in each cell cycle was measured. Strains from patients with open-type gastritis progressed more rapidly through cell cycles than those from patients with GC. NRB isolated from gastric cancer had high nitrate-reducing activity. Thus, NRB may contribute to GC progression during H. pylori-induced carcinogenesis. Therefore, evaluating gastric atrophy and microbiota may be important for managing the risk of GC. en-copyright= kn-copyright= en-aut-name=KuwagiSerika en-aut-sei=Kuwagi en-aut-mei=Serika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=KomatsubaraMarina en-aut-sei=Komatsubara en-aut-mei=Marina 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=OkanoueShyoutarou en-aut-sei=Okanoue en-aut-mei=Shyoutarou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=WatanabeAkari en-aut-sei=Watanabe en-aut-mei=Akari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YokotaKenji en-aut-sei=Yokota en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Bacteriology, Academic Field of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Bacteriology, Academic Field of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Bacteriology, Academic Field of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Bacteriology, Academic Field of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Academic Field of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Himeji Red Cross Hospital kn-affil= affil-num=7 en-affil=Department of Bacteriology, Academic Field of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral Health Care and Rehabilitation, Institute of Biomedical Sciences, Graduate School, Tokushima University kn-affil= affil-num=9 en-affil=Department of Bacteriology, Academic Field of Health Sciences, Okayama University kn-affil= en-keyword=Helicobacter pylori infection kn-keyword=Helicobacter pylori infection en-keyword=gastric cancer kn-keyword=gastric cancer en-keyword=nitrate-reducing bacteria kn-keyword=nitrate-reducing bacteria en-keyword=gastritis kn-keyword=gastritis 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=20260318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Suppression of salt-enhanced apoplastic flow by salicylic acid in rice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Salinity 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=42 cd-vols= no-issue= article-no= start-page=1806 end-page=1810 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=An electric field temporarily strengthens zirconia ceramics en-subtitle= kn-subtitle= en-abstract= kn-abstract=By applying an electric field to yttria-stabilized zirconia (8YSZ) equipped with an inert electrode, oxide ions are localized near the positive electrode, causing it to expand. When polarization was performed under different conditions, it was possible to strengthen the material to 1.5 times that of an untreated sample. The lattice constant of the positive electrode surface after polarization was larger than before polarization. When the Vickers hardness of the positive electrode surface was measured by changing the test load, the smaller the load, the higher the hardness value. Polarization caused oxide ions to move near the positive electrode, filling in the defects and generating an expanded layer with a large lattice constant. It is believed that this was subjected to compressive stress from the bulk layer, which had not changed in volume, resulting in an increase in strength. en-copyright= kn-copyright= en-aut-name=KishimotoAkira en-aut-sei=Kishimoto en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimizuTakahiro en-aut-sei=Shimizu en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishiyamaMitsuru en-aut-sei=Nishiyama en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KondoShinya en-aut-sei=Kondo en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TeranishiTakashi en-aut-sei=Teranishi en-aut-mei=Takashi 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=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Poling kn-keyword=Poling en-keyword=Zirconia ceramics kn-keyword=Zirconia ceramics en-keyword=Strengthening kn-keyword=Strengthening en-keyword=Internal stress kn-keyword=Internal stress END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=253 end-page=266 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=How Can School Counselors Contribute to Developmentally Supportive Student Guidance: An Examination of Support Expansion Through the Use of Planning Sheets kn-title=スクールカウンセラーは発達支持的生徒指導へいかに貢献できるか ―プランニングシートの活用を通した支援の拡充に向けた検討― en-subtitle= kn-subtitle= en-abstract= In the revised Guidelines for Student Guidance (2022), the importance of developmentally supportive student guidance, which aims to foster the growth of all students, is clearly emphasized. However, many challenges to its implementation have been identified in school settings, including teachers’ excessive workload and insufficient organizational support systems. Moreover, the support provided by school counselors (SCs) has not yet been sufficiently developed. Therefore, this study examined the potential for expanding SCs’ support in developmentally supportive student guidance by reviewing its current status and challenges. Furthermore, through a reanalysis of a practical case using the Planning Sheet (Hara et al., 2024), the study explored the usefulness of this framework in enabling SCs and schools to share educational goals and collaboratively plan their support activities. kn-abstract= 2022年に改訂された「生徒指導提要」では,すべての児童生徒の成長を支援する発達支持的生徒指導の重要性が明確に示されている。しかし,その定着には,教員の多忙化や組織的支援体制の不十分さなど,学校現場における多くの課題が指摘されている。さらに,スクールカウンセラー(SC)による支援も十分に展開されているとは言い難い。そこで本稿では,発達支持的生徒指導におけるSCの支援の拡充可能性を検討するため,現状と課題を整理した。また,プランニングシートを活用した実践事例(原他, 2024)の再分析を通して,SCと学校が教育目標を共有しながら協働的に支援を計画する枠組みの有用性を吟味した。 en-copyright= kn-copyright= en-aut-name=HARANoriyuki en-aut-sei=HARA en-aut-mei=Noriyuki kn-aut-name=原範幸 kn-aut-sei=原 kn-aut-mei=範幸 aut-affil-num=1 ORCID= en-aut-name=MISAWARyo en-aut-sei=MISAWA en-aut-mei=Ryo kn-aut-name=三沢良 kn-aut-sei=三沢 kn-aut-mei=良 aut-affil-num=2 ORCID= en-aut-name=AOKITazuko en-aut-sei=AOKI en-aut-mei=Tazuko kn-aut-name=青木多寿子 kn-aut-sei=青木 kn-aut-mei=多寿子 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山県公立学校スクールカウンセラー affil-num=2 en-affil= kn-affil=岡山大学学術研究院教育学域 affil-num=3 en-affil= kn-affil=岡山大学学術研究院教育学域 en-keyword=発達支持的生徒指導 (developmentally supportive student guidance) kn-keyword=発達支持的生徒指導 (developmentally supportive student guidance) en-keyword=プランニングシート (Planning Sheet) kn-keyword=プランニングシート (Planning Sheet) en-keyword=スクールカウンセラー (school counselor) kn-keyword=スクールカウンセラー (school counselor) en-keyword=チーム学校 (school as a team) kn-keyword=チーム学校 (school as a team) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=221 end-page=235 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=Designing an Educational Model and Assessing Outcomes for the Graduate Course “Leadership and SDGs” New Directions in Leadership Education through Theory Learning, Peer Review, and Reflective Practice kn-title=大学院共通科目『リーダーシップとSDGs』の教育モデル構築と成果分析 理論学習・ピアレビュー・省察活動によるリーダーシップ教育の新展開 en-subtitle= kn-subtitle= en-abstract=Okayama University's graduate school has developed and implemented a core course, “Leadership and SDGs,” to foster leadership among graduate students.

The goal of this practice is to foster a change in students' awareness of their town by having them interpret the future and nature of the town from various perspectives in relation to their interactions with others, and consider sustainable ways of living in the town and forming relationships as their own concern. As a result of the practice, students experienced changes in their perspectives and awareness regarding the town and were able to think about the regional issues involved in town development as their own concern. kn-abstract= 本研究は,中学校総合的な学習の時間における町づくりにおいて,他者との協働や相互作用を通じて町づくりを構想し,実践の結果生じた学習者の変化からその効果を明らかにすることを目的としている。また,対話的な学びで重視される他者との相互作用を,中学校の実践に落とし込み,そのあり方についても検討する。本実践のねらいは,多様な視点から町の将来の姿やあり方を人との関わりについて読み解き,持続可能な町のあり方について自分事に引き寄せて考えることで,町に対する意識の変化を促すことにある。実践の結果,学習者の町に対する見方や考え方の意識変化が引き起こされ,町づくりの持つ地域課題について自分事に引き寄せて思考することができた。 en-copyright= kn-copyright= en-aut-name=KAMADAAkemi en-aut-sei=KAMADA en-aut-mei=Akemi kn-aut-name=鎌田明美 kn-aut-sei=鎌田 kn-aut-mei=明美 aut-affil-num=1 ORCID= en-aut-name=KAJIIKazuaki en-aut-sei=KAJII en-aut-mei=Kazuaki kn-aut-name=梶井一暁 kn-aut-sei=梶井 kn-aut-mei=一暁 aut-affil-num=2 ORCID= affil-num=1 en-affil=Anan City Anan First Junior High School kn-affil=阿南市立阿南第一中学校 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=総合的な学習の時間 (the period for integrated studies) kn-keyword=総合的な学習の時間 (the period for integrated studies) en-keyword=中学生 (junior high school student) kn-keyword=中学生 (junior high school student) en-keyword=町づくり (community development) kn-keyword=町づくり (community development) en-keyword=対話的な学び (int eractive lea rning) kn-keyword=対話的な学び (int eractive lea rning) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=153 end-page=165 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=Methods for Implementing Legal Education in Social Studies to Foster Understanding of Criminal Law Through Developing Junior High School Social Studies Lessons Incorporating Mock Trials kn-title=刑法の意義を捉えさせる社会科における法教育実践の方法 ―模擬裁判を取り入れた中学校社会科の授業開発を通して― en-subtitle= kn-subtitle= en-abstract=This study focuses on developing junior high school social studies lessons incorporating mock trials to enhance understanding of criminal law. Legal education in Japanese social studies has traditionally centered on constitutional studies, with very few opportunities to learn about other laws. Given this situation, recent years have seen the development of legal education lessons covering civil law, criminal law, and other areas. Meanwhile, since the introduction of the lay judge system, the development and implementation of social studies lessons incorporating mock trials have become commonplace, and it is no longer unusual for criminal cases to be addressed in social studies classes. This study examines the characteristics and challenges of conventional mock trial-based lessons and aims to develop a junior high school social studies lesson that helps students grasp the significance of criminal law. kn-abstract= 本研究は、刑法の理解に焦点をあて、模擬裁判を取り入れた中学校社会科の授業開発を行なおうとするものである。日本の社会科における法教育は、従来から憲法学習が中心となっており、その他の法律について学ぶ機会は非常に少ない。そのような現状を踏まえて、近年、民法や刑法などを取り上げた法教育の授業開発が行われるようになった。その一方で、裁判員制度導入以降、模擬裁判を取り入れた社会科授業の開発・実践がよく見られるようになっており、刑事事件が社会科授業で取り上げられることも珍しくはなくなった。しかし、そのような授業を担当する教員に、刑法等に関する知識が十分ではなく、模擬裁判の内容と実際の裁判が乖離しているという課題もある。本研究では、従来の模擬裁判を取り入れた授業の特質と課題を検討したうえで、刑法の意義を捉えさせる中学校社会科の授業開発を目指す。 en-copyright= kn-copyright= 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=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= affil-num=1 en-affil=Graduate School of Human ities and So cial 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 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=授業開発研究 (Lesson development research) kn-keyword=授業開発研究 (Lesson development research) en-keyword=中学校社会科 (Junior high school social studies) kn-keyword=中学校社会科 (Junior high school social studies) en-keyword=模擬裁判 (Mock trial) kn-keyword=模擬裁判 (Mock trial) en-keyword=刑法 (Criminal law) kn-keyword=刑法 (Criminal law) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=139 end-page=152 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 Issues on Differences in Hours of Attendance as Seen in an Interview of Initial Appointment Child Care Teachers kn-title=初任保育教諭の語りに見る園児の在園時間の違いによる実践上の課題 en-subtitle= kn-subtitle= en-abstract=In this paper, we examined practical issues and responses through interviews with novice childcare teachers with a focus on the differences in the length of kindergarteners' attendance time, which characterizes certified childcare centers. As a result, it became obvious that childcare teachers were aware of eight challenges. In addition to the challenge with respect to the “development of childcare ensuring the continuity of play” described in the “Guidelines for Education and Childcare for Certified Childcare Centers,” furthermore, a new challenge regarding “understanding of kindergarteners in consideration of their various attendance time and lifestyles” not described in it was identified. Differences in attendance time due to certification classification inevitably lead to differences in time schedules, locations, and groups during certified childcare centers life. Therefore, in order to clarify what common experiences should be established in certified childcare centers life, what differences in experience should be utilized, and what kind of childcare should be practiced based on the goals set by childcare teachers, a future challenge is to collect and organize good practice examples that have been accumulated so far in certified nurseries and to clarify indicators. kn-abstract= 本論では,幼保連携型認定こども園の特徴である園児の在園時間の違いに焦点を当て,初任保育教諭への面接調査により実践上の課題と対応について検討した。その結果,保育教諭が8つの課題を認識していることが明らかになった。また,『幼保連携型認定こども園教育・保育要領』に記述されている「遊びの連続性を保障する保育の展開」に関する課題に加えて,記述されていない「多様な在園時間や生活形態を考慮した園児理解」に関する新たな課題が見出された。認定区分による在園時間の違いは園生活における時間的スケジュールや場所,集団の違いを余儀なくされる。そのため,保育教諭が設定するねらいに基づいた園生活で何を共通経験とすべき内容として設定し,何を経験差として活かし,どのような保育を実践するか明確にすべく,これまで認定こども園で積み重ねられてきた好実践例を集積・整理し,指標を明示することが今後の課題である。 en-copyright= kn-copyright= en-aut-name=HASUIKazuya en-aut-sei=HASUI en-aut-mei=Kazuya kn-aut-name=蓮井和也 kn-aut-sei=蓮井 kn-aut-mei=和也 aut-affil-num=1 ORCID= en-aut-name=KATAYAMAMika en-aut-sei=KATAYAMA en-aut-mei=Mika kn-aut-name=片山美香 kn-aut-sei=片山 kn-aut-mei=美香 aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Health and Welfare, Kawasaki University of Medical Welfare kn-affil=川崎医療福祉大学医療福祉学部 affil-num=2 en-affil=Faculty of Education, Graduate School of Science, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=認定こども園 (Certified Children Centers) kn-keyword=認定こども園 (Certified Children Centers) en-keyword=在園時間の違い (Differences in Hours of Attendance) kn-keyword=在園時間の違い (Differences in Hours of Attendance) en-keyword=実践上の課題 (Issues in Childcare) kn-keyword=実践上の課題 (Issues in Childcare) en-keyword=初任保育教諭 (Initial Appointment Child Care Teachers) kn-keyword=初任保育教諭 (Initial Appointment Child Care Teachers) 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.

It examined the causes of this confusion, identifying insufficient awareness of experimental conditions such as the light source, screen, and observation location. To investigate, the study analyzed changes in the Course of Study for Lower Secondary Schools and textbooks and conducted a questionnaire survey of science teachers. The results revealed that while textbook descriptions have shifted toward specifying the observation location, teaching methods among teachers vary, causing confusion of students. To address these issues, a 3D-printed teaching material was developed that naturally fixes the observation viewpoint. Its effectiveness was examined through teacher training. This material was found to be effective in promoting students' intuitive understanding and bringing inquiry-based learning. kn-abstract= 本研究は、中学校理科の凸レンズ学習で生徒が像の向きに抱く混乱に着目した。その要因を、光源・スクリーン・観察場所といった実験条件が十分に意識されてこなかった点にあると考察し、学習指導要領と教科書の変遷分析、および現職教員へのアンケート調査を実施した。その結果、教科書の記述は観察場所を指定する方向へ変化しているものの、現場教員の指導法にはばらつきがあり、生徒の混乱を招く一因となっていることを明らかにした。これらの課題解決のため、観察視点を自然に固定できる3D プリンタ製教材を開発し、教員研修でその有効性を検討した。本教材は生徒の直感的理解を促し、探究的な学びを引き出す上で有効であることが示唆された。 en-copyright= kn-copyright= en-aut-name=TANIMOTOKunihiko en-aut-sei=TANIMOTO en-aut-mei=Kunihiko kn-aut-name=谷本薫彦 kn-aut-sei=谷本 kn-aut-mei=薫彦 aut-affil-num=1 ORCID= en-aut-name=INADAYoshihiko en-aut-sei=INADA en-aut-mei=Yoshihiko kn-aut-name=稲田佳彦 kn-aut-sei=稲田 kn-aut-mei=佳彦 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=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=凸レンズ (Convex lens) kn-keyword=凸レンズ (Convex lens) en-keyword=上下左右逆 (the orientation of images) kn-keyword=上下左右逆 (the orientation of images) en-keyword=教科書 (Textbooks) kn-keyword=教科書 (Textbooks) en-keyword=学習指導要領 (Course of Study) kn-keyword=学習指導要領 (Course of Study) en-keyword=3D プリンタ (3D printer) kn-keyword=3D プリンタ (3D printer) 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.

This inherent instability presents significant challenges for the production, purification, and analysis of autoantigens in laboratory settings. Cysteine-specific cationization can effectively solubilize and purify these challenging proteins, allowing the isolation of full-length water-soluble antigens in their denatured state. The purified antigens enable accurate multiplex autoantibody assays using a suspension Luminex bead array platform. However, well-validated positive control antibodies are essential to ensuring precise clinical diagnosis. In this study, we prepared and characterized a panel of control antibodies by immunizing rabbits with cysteine-specific S-cationized antigens. The resulting antibodies predominantly recognized linear epitopes and were highly effective as quality control reagents in autoantibody array assays. Additionally, these antibodies maintained their ability to bind to their native, unmodified intracellular counterparts, highlighting the usefulness of this approach for producing antibodies against intrinsically disordered proteins. Although a modest immune response against the S-cationized modification site was observed, it remained minimal and did not affect the usefulness of the antibodies for assay validation. We propose this versatile cysteine-specific cationization platform for managing unstable proteins rich in disordered regions, supporting antigen production for diagnostics, and antibody development for research and validation purposes. en-copyright= kn-copyright= en-aut-name=SakaguchiRyui en-aut-sei=Sakaguchi en-aut-mei=Ryui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyamotoAi en-aut-sei=Miyamoto en-aut-mei=Ai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KutsumaRikako en-aut-sei=Kutsuma en-aut-mei=Rikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriTakeru en-aut-sei=Mori en-aut-mei=Takeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakashimaDaichi en-aut-sei=Nakashima en-aut-mei=Daichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MasuiMirei en-aut-sei=Masui en-aut-mei=Mirei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HonjoTomoko en-aut-sei=Honjo en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FutamiMidori en-aut-sei=Futami en-aut-mei=Midori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoriiMariko en-aut-sei=Morii en-aut-mei=Mariko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OshikiToshiyuki en-aut-sei=Oshiki en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FutamiJunichiro en-aut-sei=Futami en-aut-mei=Junichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=8 en-affil=Department of Bioscience, Faculty of Life Science, Okayama University of Science kn-affil= affil-num=9 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=10 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= 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 µm 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=MartínezJose G. en-aut-sei=Martínez 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.

In our previous work, we constructed a non-interactive proactive secret scheme by integrating threshold homomorphic encryption (ThHE) while reducing the communication complexity to 𝑂(𝑛). Not only is refreshing shares important but revoking the shares of users who have left the system is also essential in practical dynamic membership scenarios. However, the previous work was insufficient for supporting explicit user revocation. This study strengthens the description of roles for authorized users and proposes a scheme to achieve non-interactive share refresh and dynamic user management. In each epoch, authorized users are classified into three roles: retain, newly join, and rejoin, and they receive a broadcast of the compact ciphertext encoding both the refresh information and the revocation instructions from the trusted center (dealer). Authorized users independently derive new shares through homomorphic computations, whereas revoked users are unable to generate new shares. Hash functions are used to bind revocation parameters to the cryptographic hashes of valid users in order to guarantee integrity during revocation, allowing for effective verification without compromising non-interactivity. Our new scheme not only extends the revocation structure but also preserves the 𝑂(𝑛) communication complexity. en-copyright= kn-copyright= en-aut-name=HeYixuan en-aut-sei=He en-aut-mei=Yixuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KoderaYuta en-aut-sei=Kodera en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NogamiYasuyuki en-aut-sei=Nogami en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HudaSamsul en-aut-sei=Huda en-aut-mei=Samsul 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 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=Interdisciplinary Education and Research Field, Okayama University kn-affil= en-keyword=proactive secret sharing kn-keyword=proactive secret sharing en-keyword=user revocation kn-keyword=user revocation en-keyword=threshold homomorphic encryption kn-keyword=threshold homomorphic encryption en-keyword=non-interactive kn-keyword=non-interactive END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=21 article-no= start-page=6651 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=Integrated Authentication Server Design for Efficient Kerberos–Blockchain VANET Authentication en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vehicular Ad Hoc Network (VANET) is a fundamental component of the intelligent transportation systems (ITS), providing critical road information to users. However, the volatility of VANETs creates significant vulnerabilities from malicious actors. Thus, verifying joining entities is crucial to maintaining the VANET’s communication security. Authentication delays must stay below 100 ms to meet VANET requirements, posing a major challenge for security. Our previous research introduced a Kerberos–Blockchain (KBC) authentication system that contains two main components separately: Authentication Server (AS) and Ticket Granting Server (TGS). However, this KBC architecture required an additional server to accommodate increasing vehicle volumes in urban environments, leading to higher infrastructure costs. This paper presents an integrated authentication server that merges AS and TGS into a Combined Server (CBS) while retaining blockchain security. We evaluate it using OMNeT++ with SUMO for traffic simulation and Ganache for blockchain implementation. Results show that CBS removes the need for an extra server while keeping authentication delays under 100 ms. It also improves throughput by 104% and reduces signaling overhead by 45% compared to KBC. By optimizing authentication without compromising security, the integrated server greatly enhances the cost-effectiveness and efficiency of VANET systems. en-copyright= kn-copyright= en-aut-name=RahayuMaya en-aut-sei=Rahayu en-aut-mei=Maya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HossainMd.

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.

en-title=Patient Participation in Shared Decision-Making: A Consideration of Aspects and Challenges kn-title=Shared Decision Making における患者参加の諸相と課題の考察 en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper traces the historical development of decision-making models in healthcare while exploring the meaning and practical significance of “patient participation” within the shared decision-making (SDM) framework. SDM is a recommended approach to clinical decision-making that emphasizes mutual information sharing and deliberation between physicians and patients. Traditional models often assume that patients can clearly articulate their values, preferences, and treatment goals. However, in actual clinical settings, particularly in cases of serious illness or life-threatening situations, patients frequently face emotional distress and psychological burdens, which can hinder their active participation in decision-making and the expression of their preferences. Based on SDM theory and practice reports, this study argues that SDM should not be viewed merely as a process that promotes patient choice. Even when patients choose not to actively participate and ultimately delegate decisions to healthcare providers or family members, such a choice can represent autonomous decision-making if it arises through meaningful communication and mutual understanding. This perspective calls for a more comprehensive and flexible interpretation of patient participation in SDM practice. en-copyright= kn-copyright= en-aut-name=YOSHIDAMiho en-aut-sei=YOSHIDA en-aut-mei=Miho kn-aut-name=吉田美穂 kn-aut-sei=吉田 kn-aut-mei=美穂 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems Okayama University kn-affil=国立大学法人岡山大学学術研究院ヘルスシステム統合科学研究学域 en-keyword=Shared Decision-Making kn-keyword=Shared Decision-Making en-keyword=Patient Participation kn-keyword=Patient Participation en-keyword=Physician–Patient Relationship kn-keyword=Physician–Patient Relationship END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue= article-no= start-page=7 end-page=16 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 Preliminary Study on Nursing Care Technology: A Case Study of Elderly Care kn-title=介護技術論試論―高齢者介護を事例として― en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the first part of this paper, it was confirmed that the term “kaigo” (nursing care) was coined and its meaning defined during discussions on enacting social welfare legislation accompanying societal aging, as the care aspect was being “differentiated” from the “family’s health and welfare functions.” The paper also examined how the term “kaigo gijutsu”(nursing care technique) has been defined and used. In the latter part, based on the author’s own definition of “kaigo gijutsu”(nursing care technology), an attempt was made to analyze examples of technology utilization in nursing care settings, focusing on papers published in specialized welfare and nursing care technology journals. Through this preliminary study, it was shown that the author’s definition of “nursing care technology” clearly distinguishes between the means for care activities—such as welfare equipment—and the care recipients and caregivers who make use of them, and that this definition is useful for grasping the essence of challenges in nursing care settings. en-copyright= kn-copyright= en-aut-name=YOSHIBAYasuyuki en-aut-sei=YOSHIBA en-aut-mei=Yasuyuki kn-aut-name=吉葉恭行 kn-aut-sei=吉葉 kn-aut-mei=恭行 aut-affil-num=1 ORCID= affil-num=1 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil=岡山大学学術研究院ヘルスシステム統合科学学域 en-keyword=Nursing Care Technology kn-keyword=Nursing Care Technology en-keyword=Elderly Care kn-keyword=Elderly Care en-keyword=welfare equipment kn-keyword=welfare equipment END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=8840 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260317 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tribolium castaneum with longer duration of tonic immobility have more variations corresponding to the human Parkinson’s disease genomic region en-subtitle= kn-subtitle= en-abstract= kn-abstract=Parkinson’s disease (PD) is a common neurodegenerative syndrome characterized by the loss of dopaminergic neurons and is also a progressive neurodegenerative disorder that is characterized by dopamine deficiency. We established strains artificially selected for longer and shorter durations of tonic immobility, an antipredator behavior that has received much attention recently, in the red flour beetle, Tribolium castaneum, a model insect species for molecular analyses different from Drosophila melanogaster. Previous studies have shown that the long strains (L-strain) have significantly lower levels of dopamine expression in the brain than the short strains (S-strain) and that they have an abnormal pattern of locomotor activity. Furthermore, previous studies have shown that administering dopamine to L-strain beetles reduces the duration of tonic immobility. Transcriptome analysis of brain and thorax of the L- and S-strains also showed differences in mRNA expression of genes involved in dopamine synthesis and tyrosine metabolism. These results indicate that the phenotype and molecular basis of the L-strain are similar to those of Parkinson’s syndrome symptoms. In order to establish a link between T. castaneum and PD, we compared the DNA sequences of the L- and S-strains to human genes affecting dopaminergic pathways. The DNA comparison revealed many mutated regions in these genes in the L-strain. We discuss the relationship between dopaminergic pathway genes and PD-like phenotypes across humans, Drosophila, and the red flour beetle. en-copyright= kn-copyright= en-aut-name=TanakaKeisuke en-aut-sei=Tanaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SasakiKen en-aut-sei=Sasaki en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YajimaShunsuke en-aut-sei=Yajima en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=NODAI Genome Research Center, Tokyo University of Agriculture kn-affil= affil-num=2 en-affil=Graduate School of Agriculture, Tamagawa University kn-affil= affil-num=3 en-affil=NODAI Genome Research Center, Tokyo University of Agriculture kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=42 end-page=50 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=Biosensing method of growth diagnosis in the forced culture of strawberries ―Development of crop-identification algorithms― en-subtitle= kn-subtitle= en-abstract= kn-abstract=An image-processing algorithm for identifying individual crops is developed for labor-savings and time-series biological information collection. Information including the leaf development frequency are diagnostic indicators of strawberry growth. The algorithm is designed for drones in greenhouses that cannot acquire location information using the global navigation satellite system (GNSS). Drones fly over crop rows and sequentially assign identification numbers (IDs) to crops. Object-detection artificial intelligence (AI) is used to estimate the crop zone, and the ID is based on the crops number difference between frames. The previous misdetection rate was 1.06 %, failing to identify crops, which decreases to 0.31 % using the proposed algorithm. Furthermore, because there are no failures in consecutive frames, IDs are assigned to all crops correctly. en-copyright= kn-copyright= en-aut-name=TSUBOTAShogo en-aut-sei=TSUBOTA en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NAMBAKazuhiko en-aut-sei=NAMBA en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KASEIShota en-aut-sei=KASEI en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FUKATSUTokihiro en-aut-sei=FUKATSU en-aut-mei=Tokihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Institute of Agricultural Machinery, National Agriculture and Food Research Organization kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Institute of Agricultural Machinery, National Agriculture and Food Research Organization kn-affil= affil-num=4 en-affil=Institute of Agricultural Machinery, National Agriculture and Food Research Organization kn-affil= en-keyword=strawberry kn-keyword=strawberry en-keyword=forcing culture kn-keyword=forcing culture en-keyword=image-processing kn-keyword=image-processing en-keyword=object-detection kn-keyword=object-detection en-keyword=identification of individual crops kn-keyword=identification of individual crops en-keyword=drones kn-keyword=drones END start-ver=1.4 cd-journal=joma no-vol=119 cd-vols= no-issue=1 article-no= start-page=9 end-page=17 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=Big data-driven target identification by machine learning: DRD2 as a therapeutic target for psoriasis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The development of medical treatments has traditionally relied on researchers leveraging scientific knowledge to hypothesize disease mechanisms and identify therapeutic agents. However, the depletion of novel therapeutic targets has become a significant challenge, resulting in stagnation within pharmaceutical research.
Objective: To address the scarcity of therapeutic targets, we developed a machine learning (ML)-based system capable of predicting therapeutic target molecules for diseases. To validate its utility, we applied this system to psoriasis, aiming to identify novel treatment strategies.
Methods: Our approach utilized a large clinical database to calculate reporting odds ratios for all drugs associated with the prevention of diseases of interest. We identified target proteins by analyzing large chemical structure databases to discover proteins commonly associated with preventive drug candidates. Experimental validation was conducted by administering a predicted therapeutic candidate in an imiquimod-induced psoriasis mouse model.
Results: The ML-based predictions identified drugs for Parkinson’s disease as potential preventive candidates for psoriasis. Further analysis highlighted dopamine receptor D2 (DRD2) as a therapeutic target. Administration of a DRD2 agonist alleviated psoriasis symptoms in mice, evidenced by the downregulation of mRNA expression in the IL-17 pathway and reduced serum tumor necrosis factor-α levels.
Conclusion: This study demonstrates the utility of a novel ML-based system for identifying therapeutic targets, as shown by its successful application in uncovering the role of DRD2 in psoriasis. Beyond psoriasis, this system offers significant potential for exploring pathological mechanisms and discovering therapeutic targets across various diseases. en-copyright= kn-copyright= en-aut-name=SakaiTakashi en-aut-sei=Sakai en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SawadaRyusuke en-aut-sei=Sawada en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IchinoseOtoha en-aut-sei=Ichinose en-aut-mei=Otoha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TerabayashiTakeshi en-aut-sei=Terabayashi en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HatanoYutaka en-aut-sei=Hatano en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamanishiYoshihiro en-aut-sei=Yamanishi en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IshizakiToshimasa en-aut-sei=Ishizaki en-aut-mei=Toshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Dermatology, Faculty of Medicine, Oita University kn-affil= affil-num=2 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Bioscience and Bioinformatics, Faculty of Computer Science and Systems Engineering, Kyushu Institute of Technology kn-affil= affil-num=4 en-affil=Department of Pharmacology, Faculty of Medicine, Oita University kn-affil= affil-num=5 en-affil=Department of Dermatology, Faculty of Medicine, Oita University kn-affil= affil-num=6 en-affil=Department of Complex Systems Science, Graduate School of Informatics, Nagoya University kn-affil= affil-num=7 en-affil=Department of Pharmacology, Faculty of Medicine, Oita University kn-affil= en-keyword=artificial intelligence kn-keyword=artificial intelligence en-keyword=big data kn-keyword=big data en-keyword=machine learning kn-keyword=machine learning en-keyword=dopamine receptor D2 kn-keyword=dopamine receptor D2 en-keyword=psoriasis kn-keyword=psoriasis END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page=JFST0004 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=Numerical analysis validating the standard k-epsilon model for the kinetic energy of turbulence subjected to weak but long-lasting wind tunnel blockage acceleration en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study is to investigate the effect of weak but prolonged mean flow accelerations, such as those observed in wind tunnel blockage acceleration, on free-stream turbulence. Specifically, this research aims to validate a model previously developed based on the k-epsilon model. To test this model, the study focuses on scenarios where the turbulence under acceleration is steady and isotropic, since the model suggests that this type of acceleration has no effect on the turbulent kinetic energy. To examine this suggestion, the turbulence within a periodic box was analyzed using large-eddy simulation (LES) based on the conventional Smagorinsky model framework. The numerical analysis is based on a method that conserves velocity fluctuation intensities. The results show that while high rate of acceleration deviates turbulent kinetic energy, low rate acceleration has hardly any effect on turbulent kinetic energy, enstrophy, pressure fluctuation, relative pressure fluctuation intensity, and higher-order statistics of a velocity fluctuation. These results validate the accuracy of the model proposed in the previous studies. These results were obtained by focusing on differences in Reynolds numbers and the spatial scale of the forcing. en-copyright= kn-copyright= en-aut-name=ONOAkira en-aut-sei=ONO en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SUZUKIHiroki en-aut-sei=SUZUKI en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KOUCHIToshinori en-aut-sei=KOUCHI en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TANAKAKento en-aut-sei=TANAKA en-aut-mei=Kento 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 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= en-keyword=Turbulent flows kn-keyword=Turbulent flows en-keyword=Large-eddy simulation kn-keyword=Large-eddy simulation en-keyword=Homogeneous turbulence kn-keyword=Homogeneous turbulence en-keyword=K-epsilon model kn-keyword=K-epsilon model en-keyword=Wind tunnel blockage kn-keyword=Wind tunnel blockage 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=19 cd-vols= no-issue=2 article-no= start-page=dmm052605 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=A genetic model of congenital intestinal atresia implicates Mypt1 in epithelial organisation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Congenital intestinal atresia (IA) is a birth defect characterised by the absence or closure of part of the intestine. Although genetic factors are implicated, mechanistic understanding has been hindered by the lack of suitable animal models. Here, we describe a medaka (Oryzias latipes) mutant, generated by N-ethyl-N-nitrosourea (ENU) mutagenesis, that develops IA during embryogenesis. Positional cloning identified a nonsense mutation in mypt1, encoding myosin phosphatase target subunit 1. Mutant embryos exhibited ectopic accumulation of F-actin and phosphorylated myosin regulatory light chain (Mrlc) in the intestinal epithelium, consistent with disrupted actomyosin regulation. These cytoskeletal abnormalities were accompanied by epithelial disorganisation, without notable alterations in cell proliferation, motility or apoptosis. Inhibition of myh11a, encoding smooth muscle (SM) myosin heavy chain, ameliorated the IA phenotype, whereas blebbistatin treatment completely rescued the defect, suggesting a non-contractile role prior to SM maturation. Together, these findings demonstrate that mypt1 loss disrupts intestinal morphogenesis through actomyosin dysregulation. Given the recent clinical identification of IA associated with MYPT1 variants, this medaka model offers a valuable platform to investigate the developmental and molecular basis of MYPT1-associated IA in humans. en-copyright= kn-copyright= en-aut-name=KobayashiDaisuke en-aut-sei=Kobayashi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UrasakiAkihiro

with FTase inhibitory activity. 1a–1d possess a cyclopentane-1,3-dione core, which is critical for FTase recognition; a farnesyl moiety, which is a simplified motif of A to C rings of andrastin; and a carboxylic acid or methoxycarbonyl group, which enables multipoint hydrogen bonding interactions with FTase. Competitive inhibition experiments revealed that 1d has the most potent FTase inhibitory activity. Docking simulation analysis of 1a–1d with FTase suggested that the multipoint hydrogen bonding interactions between the cyclopentane-1,3-dione moiety and the carboxyl group play an important role in FTase recognition. en-copyright= kn-copyright= en-aut-name=KitamuraFumino en-aut-sei=Kitamura en-aut-mei=Fumino kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TaniokaMasaru en-aut-sei=Tanioka en-aut-mei=Masaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KosakaAyano en-aut-sei=Kosaka en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsuzawaNao en-aut-sei=Matsuzawa en-aut-mei=Nao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ObitaTakayuki en-aut-sei=Obita en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakajiriYuko en-aut-sei=Sakajiri en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShibataTomokazu en-aut-sei=Shibata en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SawadaRyusuke en-aut-sei=Sawada en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YokoyamaTakeshi en-aut-sei=Yokoyama en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KohyamaAki en-aut-sei=Kohyama en-aut-mei=Aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YamadaTsuyoshi en-aut-sei=Yamada en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YamanishiYoshihiro en-aut-sei=Yamanishi en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MizuguchiMineyuki en-aut-sei=Mizuguchi en-aut-mei=Mineyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MatsuyaYuji en-aut-sei=Matsuya en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= affil-num=2 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= affil-num=3 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= affil-num=4 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= affil-num=5 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= affil-num=6 en-affil= kn-affil= affil-num=7 en-affil=Department of Complex Systems Science, Graduate School of Informatics, Nagoya University kn-affil= affil-num=8 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= affil-num=10 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= affil-num=11 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= affil-num=12 en-affil=Department of Complex Systems Science, Graduate School of Informatics, Nagoya University kn-affil= affil-num=13 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= affil-num=14 en-affil=Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama kn-affil= en-keyword=Andrastin analogs kn-keyword=Andrastin analogs en-keyword=Farnesyl transferase (FTase) inhibitor kn-keyword=Farnesyl transferase (FTase) inhibitor en-keyword=Hydrogen bonding interactions kn-keyword=Hydrogen bonding interactions en-keyword=Cyclopentane-1,3-dione kn-keyword=Cyclopentane-1,3-dione en-keyword=Molecular docking kn-keyword=Molecular docking END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=5 article-no= start-page=1535 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Proposal of Secure and Automated Over-the-Air Firmware Update Mechanism for IoT Devices Using Continuous Integration and Continuous Delivery en-subtitle= kn-subtitle= en-abstract= kn-abstract=The Internet of Things (IoT) technology has grown rapidly over the past decade, resulting in deployments of thousands of IoT devices around the world. Then, managing firmware updates for these numerous devices poses significant challenges. Firmware updates face issues such as version rollback, modified firmware files, and potential man-in-the-middle (MITM) attacks, highlighting the need for a secure over-the-air (OTA) firmware update mechanism. In this paper, we propose an automated OTA firmware update mechanism, integrated with continuous integration (CI) and continuous delivery (CD) to ensure trusted sources for firmware origins. It offers security, error handling during firmware updates, and monitoring of the update process. For evaluations, we implemented the proposal with the SEMAR IoT application server that has been implemented in our previous studies. Then, we verified the integrity and authentication, measured the performance and resource utilization, and performed benchmarking tests to assess the efficiency. The results demonstrate that the proposal is sufficiently reliable and efficient. en-copyright= kn-copyright= en-aut-name=Noprianto en-aut-sei=Noprianto en-aut-mei= 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=BrataKomang Candra en-aut-sei=Brata en-aut-mei=Komang Candra 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= 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= en-keyword=Internet of Things (IoT) kn-keyword=Internet of Things (IoT) en-keyword=over-the-air (OTA) firmware update kn-keyword=over-the-air (OTA) firmware update en-keyword=security kn-keyword=security en-keyword=continuous integration (CI) kn-keyword=continuous integration (CI) en-keyword=continuous delivery (CD) kn-keyword=continuous delivery (CD) 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. These estimated velocity structure models provided a reasonable explanation for the observed phase velocities. en-copyright= kn-copyright= en-aut-name=YAMADANobuyuki en-aut-sei=YAMADA en-aut-mei=Nobuyuki kn-aut-name=山田伸之 kn-aut-sei=山田 kn-aut-mei=伸之 aut-affil-num=1 ORCID= en-aut-name=TAKENAKAHiroshi en-aut-sei=TAKENAKA en-aut-mei=Hiroshi kn-aut-name=竹中博士 kn-aut-sei=竹中 kn-aut-mei=博士 aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Science and Technology, Kochi University kn-affil=高知大学理工学部地球環境防災学科 affil-num=2 en-affil=Department of Earth Sciences, Okayama University kn-affil=岡山大学学術研究院環境生命自然科学学域 en-keyword=Okayama Plain kn-keyword=Okayama Plain en-keyword=Kojima Bay kn-keyword=Kojima Bay en-keyword=Microtremor array exploration kn-keyword=Microtremor array exploration en-keyword=S-wave velocity structure model kn-keyword=S-wave velocity structure model END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue= article-no= start-page=155 end-page=174 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260316 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Does Environmental Spending Reduce Firm Risk? Evidence from Japanese Companies kn-title=環境支出は企業リスクを軽減するのか?日本企業の実証分析 en-subtitle= kn-subtitle= en-abstract= kn-abstract= This study examines how environmental conservation costs (ECC) affects firm risk, using changes in leverage ratios and earnings volatility as stand-ins for risk. This study evaluates the direct impact of ECC and its relationship to profitability (ROA) using panel data of Japanese companies from 2010 to 2022 and Pooled OLS regression models. The results demonstrate the risk-mitigating function of sustainability investments by showing that, although independent ECC have little direct significance, their interaction with firm profitability dramatically lowers earnings volatility and leverage instability. These findings underscore the economic value of environmental strategies, suggesting that incorporating profitability considerations into sustainability practices enhances operational stability and reduces risk exposure. To help policymakers, investors, and corporate managers strike a balance between sustainability and financial performance, this study contributes to the growing body of research on the relationship between the environment and finance. en-copyright= kn-copyright= en-aut-name=NAZIRYUSRA en-aut-sei=NAZIR en-aut-mei=YUSRA kn-aut-name=ナジールユスラ kn-aut-sei=ナジール kn-aut-mei=ユスラ aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院社会文化科学研究科 en-keyword=Environmental Accounting kn-keyword=Environmental Accounting en-keyword=Environmental Conservation Costs kn-keyword=Environmental Conservation Costs en-keyword=Firm Risk kn-keyword=Firm Risk en-keyword=Earnings Volatility kn-keyword=Earnings Volatility en-keyword=ESG kn-keyword=ESG en-keyword=and Risk Management Leverage Ratio kn-keyword=and Risk Management Leverage Ratio en-keyword=Sustainability kn-keyword=Sustainability en-keyword=Panel Data kn-keyword=Panel Data en-keyword=Japanese Companies kn-keyword=Japanese Companies END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue= article-no= start-page=85 end-page=99 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260316 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Economic Value Generated by Innovations in Photographic Technology kn-title=写真技術のイノベーションが創出する経済価値 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MIYAZAKISatoru en-aut-sei=MIYAZAKI en-aut-mei=Satoru kn-aut-name=宮崎悟 kn-aut-sei=宮崎 kn-aut-mei=悟 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学学術研究院社会文化科学学域 END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=1 article-no= start-page=23 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260205 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Band-selective plasmonic polaron in thermoelectric semimetal Ta2PdSe6 with ultra-high power factor en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report the electronic structure of the thermoelectric semimetal Ta2PdSe6 with a large thermoelectric power factor and giant Peltier conductivity by means of angle-resolved photoemission spectroscopy (ARPES). The ARPES spectra reveal the coexistence of a sharp hole band with a light electron mass and a broad electron band with a relatively heavy electron mass, which originate from different quasi-one-dimensional (Q1D) chains in Ta2PdSe6. Moreover, the electron band around the Brillouin-zone (BZ) boundary shows a replica structure with respect to the energy originating from plasmonic polarons due to electron-plasmon interactions. The different scattering effects and interactions in each atomic chain lead to asymmetric transport lifetimes of carriers: a large Seebeck coefficient can be realized even in a semimetal. Our findings pave the way for exploring the thermoelectric materials in previously overlooked semimetals and provide a new platform for low-temperature thermoelectric physics, which has been challenging with semiconductors. en-copyright= kn-copyright= en-aut-name=OotsukiDaiki en-aut-sei=Ootsuki en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakanoAkitoshi en-aut-sei=Nakano en-aut-mei=Akitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaruokaUrara en-aut-sei=Maruoka en-aut-mei=Urara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HasegawaTakumi en-aut-sei=Hasegawa en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AritaMasashi en-aut-sei=Arita en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KitamuraMiho en-aut-sei=Kitamura en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HoribaKoji en-aut-sei=Horiba en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshidaTeppei en-aut-sei=Yoshida en-aut-mei=Teppei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TerasakiIchiro en-aut-sei=Terasaki en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Present address: Department of Applied Physics, Nagoya University kn-affil= affil-num=3 en-affil=Present address: Department of Applied Physics, Nagoya University kn-affil= affil-num=4 en-affil=Graduate School of Advanced Science and Engineering, Hiroshima University kn-affil= affil-num=5 en-affil=Research Institute for Synchrotron Radiation Science, Hiroshima University kn-affil= affil-num=6 en-affil=Present address: NanoTerasu Center, National Institutes for Quantum Science and Technology (QST) kn-affil= affil-num=7 en-affil=Present address: NanoTerasu Center, National Institutes for Quantum Science and Technology (QST) kn-affil= affil-num=8 en-affil=Graduate School of Human and Environmental Studies, Kyoto University kn-affil= affil-num=9 en-affil=Present address: Department of Applied Physics, Nagoya University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=160 end-page=164 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=Verification of a Skin Electrical Impedance Model for Evaluating Indicators of Skin Barrier Function of Older Adults en-subtitle= kn-subtitle= en-abstract= kn-abstract=Skin barrier function has been quantitatively evaluated through trans-epidermal water loss, which has been difficult to measure in clinical settings owing to environmental factors and the measurement time. The thickness and surface water content of the stratum corneum are important indicators of skin barrier function, and current methods for measuring these two indicators are also difficult to implement in clinical settings. Therefore, we developed a model based on skin electrical impedance to estimate the thickness and water content of the stratum corneum, enabling measurement and estimation of these two indicators in a short time. In this study, we verified this model implemented in a portable skin electrical impedance measurement device for estimating the thickness and surface water content of the stratum corneum of the skin in older adults. Thirty-four older individuals were studied. The measurement electrodes were placed in contact with the forearm skin, and an alternating signal of two frequencies was applied to measure the impedance, from which the thickness and surface water content of the stratum corneum were estimated in approximately 5 s. The correlation coefficients between the estimated and measured thickness and between the estimated and measured surface water content were 0.732 and 0.604, respectively. Furthermore, the root mean square errors of the residuals for the thickness and surface water content were 1.66 µm and 3.50 points, respectively, indicating that the model accurately estimated the thickness and surface water content of the stratum corneum, even in the skin of older adults. en-copyright= kn-copyright= en-aut-name=UEHARAOsamu en-aut-sei=UEHARA en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FUNAKIYuya en-aut-sei=FUNAKI en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NAKAMURATakao en-aut-sei=NAKAMURA en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Medical Engineering Laboratory, ALCARE Co., Ltd. kn-affil= affil-num=2 en-affil=Medical Engineering Laboratory, ALCARE Co., Ltd. kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=older adults kn-keyword=older adults en-keyword=stratum corneum thickness kn-keyword=stratum corneum thickness en-keyword=stratum corneum surface water content kn-keyword=stratum corneum surface water content 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=41 end-page=91 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=Re-theorizing Consumer Behavior in the Age of Human–AI Coexistence: The AIBCBM Framework kn-title=AI 共生時代における消費者行動の再理論化―AIBCBM フレームワーク― en-subtitle= kn-subtitle= en-abstract= This study aims to construct and present the AI-Based Consumer Behavior Model(AIBCBM) as a theoretical framework that systematically explains the tripartite interaction among companies, consumers, and AI in environments where AI intervenes from the pre-decision stage. First, it identifies the critical theoretical limitations of existing consumer behavior models, which fail to adequately address contemporary phenomena such as algorithmic exposure, recursive learning loops, and AI-mediated social influence. Building upon this, the study presents the AIBCBM (AI-Based Consumer Behavior Model), which conceptualizes consumer behavior in the era of AI symbiosis as a tripartite cyclical structure involving“ business–AI–consumer.”
 In constructing the model, rather than oversimplifying complex reality, theoretical clarity and analytical tractability are ensured by separating it into a tripartite co-evolutionary structure model (Figure 2), a behavioral process model illustrating the dynamics of behavior generation(Table 3), a conceptual structure model(Figure 3), and a behavioral typology model(Figure 4). The theoretical contributions of this study are summarized in five points:
(1) redefining System 1 as a behavioral generation mechanism;
(2) redefining decision-making agents and power structures;
(3) theoretically modeling nonlinear, high-speed feedback loops in consumer behavior;
(4) Theoretical redefinition of non-consumption and JOMO as strategic behaviors grounded in well-being and human agency.
(5) reconceptualizing consumer behavior from a "decision-making model" to a "behavior generation model."
 Moreover, the duality highlighted in this study—where algorithm-driven utility enhancement and autonomy impairment can coexist—provides a new normative and theoretical evaluation framework for marketing strategies and policy design in the AI era. AIBCBM functions as a theoretical platform that integrates these perspectives, serving as a foundation for future theoretical development and empirical validation. In particular, AIBCBM is distinctive in positioning JOMO and non-consumption not as passive withdrawal from algorithmic environments, but as strategic behaviors through which consumers intentionally calibrate their distance from AI-constructed choice architectures to preserve human agency, well-being, and human-likeness.
 Finally, the proposed model serves as a theoretical coordinate framework that systematically connects firm-side AI design, algorithmic dynamics, and consumer agency and well-being, thereby bridging empirical inquiry and normative design in the age of AI co-existence. kn-abstract= 本研究は,AIが意思決定の前段階から介入する環境において,企業・消費者・AIの三者相互作用を体系的に説明する理論枠組みとして,Artificial Intelligence-Based Consumer Behavior Model(AIBCBM)を構築し,提示することを目的とする。まず,既存の消費者行動モデルが,アルゴリズム露出,再帰的学習ループ,AI媒介型社会的影響(Algorithmic Social Influence)といった現代的現象を十分に扱えないという決定的な理論的限界を明らかにする。そのうえで,AI共生時代における消費者行動を,「企業-AI-消費者」の三者循環構造として捉えるAIBCBMを提示する。
 モデル構築に際しては,複雑な現実を過度に単純化するのではなく,三者共進化構造モデル(図2),行動生成の動態を示す行動プロセスモデル(表3),概念構造モデル(図3),行動類型モデル(図4)に分離することで,理論的明瞭性と分析可能性を確保した。本研究の理論的貢献は,①System 1を行動生成メカニズムとして再定義した点,②意思決定主体と権力構造を再定義した点,③消費者行動における非線形・高速フィードバックループを理論化した点,④非消費やJOMOを,幸福と主体性に根ざした戦略的行動として理論的に再定義した点,⑤消費者行動を「意思決定モデル」から「行動生成モデル」へ理論的に転換した点に集約される。さらに,本研究が提示する,アルゴリズムによる効用の向上と自律性の毀損が併存しうるという二面性は,AI時代におけるマーケティング戦略および政策設計に対して,規範的かつ理論的な新たな評価軸を提供する。AIBCBMは,これらの視座を統合する理論的プラットフォームとして,今後の実証研究に向けた基盤として機能する。とりわけ, AIBCBMは,JOMOや非消費行動を,アルゴリズム環境からの受動的撤退ではなく,AIによって構築された選択環境との距離を意図的に調整し,人間らしさ(人間としての主体性やウェルビーイング)を保持するための戦略的行動として位置づける点に独自性を有する。さらに本モデルは,AI設計(企業側)・アルゴリズム動態(AI側)・主体性とウェルビーイング(Well-being)(消費者側)を同一枠組みで接続することで,AI共生時代の実証研究と規範設計を架橋する理論的座標軸を確立する。 en-copyright= kn-copyright= en-aut-name=ShazadigulSawut en-aut-sei=Shazadigul en-aut-mei=Sawut kn-aut-name=夏扎提古丽沙吾提 kn-aut-sei=夏扎提古丽 kn-aut-mei=沙吾提 aut-affil-num=1 ORCID= affil-num=1 en-affil=Faculty of Humanities and Social Sciences, Okayama University kn-affil= en-keyword=行動生成モデル (Behavior Generation Model) kn-keyword=行動生成モデル (Behavior Generation Model) en-keyword=人間-AIの共同主体性 (Human-AI Co-agency/Shared Agency) kn-keyword=人間-AIの共同主体性 (Human-AI Co-agency/Shared Agency) en-keyword=アルゴリズム的選択環境 (Algorithmic Choice Architecture) kn-keyword=アルゴリズム的選択環境 (Algorithmic Choice Architecture) en-keyword=非消費/意図的な非使用 (Non-consumption/Intentional Non-use) kn-keyword=非消費/意図的な非使用 (Non-consumption/Intentional Non-use) en-keyword=再帰的学習ループ (Recursive Learning Loops) kn-keyword=再帰的学習ループ (Recursive Learning Loops) 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=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=69 cd-vols= no-issue=5 article-no= start-page=5944 end-page=5955 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260218 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Discovery of Thermal Sensitizers That Inhibit Heat-Induced SAFB Granule Formation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hyperthermia is a minimally invasive cancer treatment based on heat stress-induced apoptosis. Its therapeutic efficacy, however, is often limited by tumor heterogeneity and acquired thermotolerance. Therefore, combination strategies involving hyperthermia and chemotherapy have been developed to enhance the therapeutic efficacy. Previously, we showed that SB366791 enhanced heat-induced apoptosis by inhibiting heat stress-induced scaffold attachment factor B (SAFB) granule formation, although its proapoptotic activity was insufficient. Therefore, we screened to identify novel compounds that enhance heat-induced apoptosis by suppressing SAFB granule formation. We identified four hit compounds that inhibited SAFB granule formation, all exhibiting thermal enhancement ratios > 1.0─that significantly enhanced heat-induced apoptosis efficiency. Additionally, the tumor volume in mice treated with a combination of Z19024498 and hyperthermia was significantly smaller than that in mice treated with hyperthermia or Z19024498. These results indicate that the identified compounds, specifically Z19024498, have potential as thermal sensitizers for hyperthermia therapy. en-copyright= kn-copyright= en-aut-name=FurutaniYuji en-aut-sei=Furutani en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimasakiNatsuki en-aut-sei=Shimasaki en-aut-mei=Natsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamadaRiko en-aut-sei=Yamada en-aut-mei=Riko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OhtsukiTakashi en-aut-sei=Ohtsuki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WatanabeKazunori en-aut-sei=Watanabe en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= 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=11 cd-vols= no-issue=3 article-no= start-page=e198959 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251223 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Collagen-binding C-type natriuretic peptide enhances chondrogenesis and osteogenesis en-subtitle= kn-subtitle= en-abstract= kn-abstract=C-type natriuretic peptide (CNP) is known to promote chondrocyte proliferation and bone formation; however, CNP’s extremely short half-life necessitates continuous intravascular administration to achieve bone-lengthening effects. Vosoritide, a CNP analog designed for resistance to neutral endopeptidase, allows for once-daily administration. Nonetheless, it distributes systemically rather than localizing to target tissues, which may result in adverse effects such as hypotension. To enhance local drug delivery and therapeutic efficacy, we developed a potentially novel synthetic protein by fusing a collagen-binding domain (CBD) to CNP, termed CBD-CNP. This fusion protein exhibited stability under heat conditions and retained the collagen-binding ability and bioactivity as CNP. CBD-CNP localized to articular cartilage in fetal murine tibiae and promoted bone elongation. Spatial transcriptomic analysis revealed that the upregulation of chondromodulin expression may contribute to its therapeutic effects. Treatment of CBD-CNP mixed with collagen powder to a fracture site of a mouse model increased bone mineral content and bone volume compared with CNP-22. Intraarticular injection of CBD-CNP to a mouse model of knee osteoarthritis suppressed subchondral bone thickening. By addressing the limitations of CNP’s rapid degeneration, CBD-CNP leverages its collagen-binding capacity to achieve targeted, sustained delivery in collagen-rich tissues, offering a promising strategy for enhancing chondrogenesis and osteogenesis. en-copyright= kn-copyright= en-aut-name=HiraiKenta en-aut-sei=Hirai en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SawamuraKenta en-aut-sei=Sawamura en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EsakiRyusaku en-aut-sei=Esaki en-aut-mei=Ryusaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SawadaRyusuke en-aut-sei=Sawada en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkushaYuka en-aut-sei=Okusha en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AoyamaEriko en-aut-sei=Aoyama en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaitoHiroki en-aut-sei=Saito en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UchidaKentaro en-aut-sei=Uchida en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MimaTakehiko en-aut-sei=Mima en-aut-mei=Takehiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ImagamaShiro en-aut-sei=Imagama en-aut-mei=Shiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MatsushitaMasaki en-aut-sei=Matsushita en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 ORCID= en-aut-name=HosonoYasuyuki en-aut-sei=Hosono en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Nagoya University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Nagoya University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Advanced Research Center for Oral and Craniofacial Sciences, Okayama University Dental School kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Kitasato University School of Medicine kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Kitasato University School of Medicine kn-affil= affil-num=9 en-affil=Department of Medical Technology, Faculty of Health Sciences, Ehime Prefectural University of Health Sciences kn-affil= affil-num=10 en-affil=Department of Biochemistry and Molecular DentistryBacteriology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Orthopaedic Surgery, Nagoya University Graduate School of Medicine kn-affil= affil-num=13 en-affil=Department of Orthopaedic Surgery, Nagoya University Graduate School of Medicine kn-affil= affil-num=14 en-affil=Department of Bacteriology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=15 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=2 article-no= start-page=199 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260128 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Targeting the Gut in Sepsis: Therapeutic Potential of Medical Gases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sepsis is a life-threatening condition characterized by a dysregulated host response to infection, often resulting in multiorgan dysfunction. Among affected systems, the gastrointestinal tract plays a central role in sepsis progression by promoting systemic inflammation through impaired barrier function, immune imbalance, and microbiome alterations. Recent research has identified selected medical gases and gasotransmitters as promising therapeutic candidates for preserving gut integrity in sepsis. In particular, hydrogen, carbon monoxide, and hydrogen sulfide exhibit antioxidative, anti-inflammatory, and cytoprotective properties. These gases act through defined molecular pathways, including activation of Nrf2, inhibition of NF-κB, and preservation of tight junction integrity, thereby supporting intestinal barrier function. In addition, they influence immune cell phenotypes and autophagy, with indirect effects on the gut microbiome. Although most supporting evidence derives from preclinical models, translational findings and emerging safety data highlight the potential of gut-targeted gas-based strategies. This review summarizes current mechanistic and translational evidence for gut-protective medical gases in sepsis and discusses their integration into future organ-specific and mechanism-based therapeutic approaches. en-copyright= kn-copyright= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 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=4 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=carbon monoxide kn-keyword=carbon monoxide en-keyword=gastrointestinal tract kn-keyword=gastrointestinal tract en-keyword=gut kn-keyword=gut en-keyword=hydrogen kn-keyword=hydrogen en-keyword=hydrogen sulfide kn-keyword=hydrogen sulfide en-keyword=sepsis kn-keyword=sepsis en-keyword=septic shock kn-keyword=septic shock 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=

Escherichia coli yaiX Confers Multidrug Resistance and Enhances Virulence in the Silkworm Infection Model en-subtitle= kn-subtitle= en-abstract= kn-abstract=The emergence of bacteria with both antimicrobial resistance and high virulence has become a global health concern, underscoring the urgent need to elucidate the molecular basis underlying these traits. Here, we employed the silkworm (Bombyx mori) infection model, which is suitable for high-throughput screening, together with an Escherichia coli library containing plasmid clones of all genes from strain W3110, to identify genes whose overexpression enhances virulence. We found that overexpression of the uncharacterized protein YaiX promoted bacterial proliferation in silkworms and increased host lethality. Compared with the empty-vector control, the YaiX-overexpressing strain exhibited resistance to multiple antimicrobial agents with diverse mechanisms of action, including β-lactams, tetracyclines, fluoroquinolones, aminoglycosides, cationic surfactants, and hydrogen peroxide. Sequence analysis revealed that amino acids 18–52 of YaiX contain a transferase hexapeptide domain predicted to form a left-handed parallel β-helix. Overexpression of YaiX mutants lacking regions outside this domain conferred ampicillin resistance, whereas deletion of the hexapeptide domain abolished this phenotype. RNA sequencing and GO enrichment analyses further indicated that YaiX overexpression altered the expression of genes encoding RNA-binding proteins and porins. These findings suggest that YaiX overexpression, through its hexapeptide domain, modulates gene expression and contributes to both multidrug resistance and enhanced virulence in E. coli. en-copyright= kn-copyright= en-aut-name=HonguKinuka en-aut-sei=Hongu en-aut-mei=Kinuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshikawaKazuya en-aut-sei=Ishikawa en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KosakiTomoki en-aut-sei=Kosaki en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=FurutaKazuyuki en-aut-sei=Furuta en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KaitoChikara en-aut-sei=Kaito en-aut-mei=Chikara 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=Research Center for Intestinal Health Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Escherichia coli kn-keyword=Escherichia coli en-keyword=hexapeptide domain kn-keyword=hexapeptide domain en-keyword=multidrug resistance kn-keyword=multidrug resistance en-keyword=pseudogene function kn-keyword=pseudogene function en-keyword=RNA‐seq kn-keyword=RNA‐seq en-keyword=silkworm infection model kn-keyword=silkworm infection model en-keyword=virulence kn-keyword=virulence en-keyword=yaiX kn-keyword=yaiX 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=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.

Model of Pancreatic Cancer Fibrosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fibrosis is a significant barrier to drug delivery in pancreatic ductal adenocarcinoma (PDAC) and contributes to its dismal prognosis. Pancreatic stellate cells (PSCs) drive fibrosis by excessively secreting extracellular matrix proteins such as collagen I. Collagen I is thought to physically obstruct the delivery of macromolecules, such as albumin, antibodies, and nanomedicines. Apart from its structural role, collagen signals through dedicated cell surface receptors, such as the discoidin domain receptors (DDR) 1/2. However, whether and how collagen signaling contributes to fibrotic barrier generation remains uncharacterized. Here, a 3D culture model of PDAC fibrosis constructed from patient PSCs is used to assess the contribution of DDR1/2-mediated collagen signaling. DDR1/2 inhibition diminishes collagen I expression in PSCs to enhance macromolecular delivery. Moreover, MEK inhibitors exacerbate the fibrotic barrier by up-regulating collagen I, an effect reversed by inhibiting DDR1/2. Through isoform-specific targeting, inhibiting DDR1, but not DDR2, is shown to be effective. Downstream of DDR, the involvement of the PI3K/AKT/mTOR pathway is demonstrated, particularly alternative mTOR complexes involving MEAK7 and GIT1. Altogether, the results show in vitro that DDR1-mediated collagen signaling exacerbates the fibrotic barrier and may be targeted to enhance macromolecular drug delivery in PDAC. en-copyright=

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=

本研究は,発達支持的教育相談として実施した強み認識授業が,青年の自己の強み選択の難易度に及ぼす影響を探索的に検討したものである。研究1では中国地方の公立中学校423名を対象にオンラインで,研究2では専門学校学生86名,大学生93名を対象に対面で,強み認識授業を実施し,授業後に,自己の強み選択の難易度を測定した。その結果,すべての群の強み選択の難易度の評価は,平野(2019)と比較して「容易である」との回答傾向を示した(Mdn = 7)。また,3群の強み選択の難易度の分布に統計的な有意差は認められなかった(p = .222)。この知見は,本授業が対象者の発達段階や実施形式(オンライン・対面)に関わらず,普遍的に強み特定を支援する機能を持つ可能性を示唆する。最後に,この知見をもとに,学校現場での教育相談の新たな展開を提言した。 en-copyright= kn-copyright=

本研究は,清田哲男の理論枠組を基盤として,教員が日常生活で出会う市井の他者との対話を通じて創造性や授業観を変容させるプロセスを明確化したものである。市井プロジェクトの質的分析により,教員は他者の生き方や姿勢から新たな価値を受け取り(市井からの享受過程),その経験を契機に教育観を再編し(教育観変容過程),さらに授業構想に具体的変化を生じさせること(授業内容関与過程)が確認された。とりわけ,制度的研修では得にくい偶発的対話や生活知の受容が,教員の創造性を喚起し,日常に根ざした学びとして機能する点が成果である。本研究は,教員自身が学ぶ創造性という新たな研究領域の基盤を形成し,美術教育における創造性育成の新たな可能性を提示した。

入(MW・空想)の4 つを想定した。またその内言が自己の成長にとって意味のある内言か否かを判断する 指標として本来感を用いた。分析の結果, 本来感高群において, MW による集中力の欠如が人の思考を 多領域にさまよわせ, 内的な個性の創造と内的な個人の成長を促すことが示された。また低群において 省察は自分らしさを求め変容を目指す意識が促進されることが示された。他方, 反芻と空想はいずれの

Examination for Specialists and Instructors in the Japanese Society of Neuroendovascular Therapy: History and Current Status en-subtitle= kn-subtitle= en-abstract= kn-abstract=Neuroendovascular therapy is a key treatment for cerebrovascular disorders, driven by advancements in devices and techniques. The Japanese Society for Neuroendovascular Therapy (JSNET) established a certification system in 1997 to ensure operator competence and minimize complications, with the first examination in 2002. JSNET offers 2 main certifications: specialist and instructor. Specialists perform basic procedures, while instructors lead in practice, education, and research. In 2020, the mechanical thrombectomy practitioner qualification was added to promote mechanical thrombectomy. Applicants must have a JSNET membership, relevant certifications, training, and documented experience. The certification process includes rigorous written and practical examinations that now employ non-fluoroscopic models. Certification renewal every 5 years requires conference participation and a continuing education program. Public awareness and integration into stroke center designations have grown. Over 2200 specialists, including more than 500 instructors, have been certified, significantly advancing neuroendovascular therapy in Japan. JSNET aims to continue improving certification and education to maintain high standards. en-copyright= kn-copyright= en-aut-name=YoshimuraShinichi en-aut-sei=Yoshimura en-aut-mei=Shinichi kn-aut-name=

en-subtitle= kn-subtitle= en-abstract= kn-abstract=The present study examines an OpenFOAM-based LES analysis from the viewpoints of inviscid energy conservation and viscous turbulence decay. The Smagorinsky model is employed as the sub-grid scale (SGS) model, and a two-dimensional periodic analytical solution and a three-dimensional periodic Taylor-Green vortex (TGV) are employed to represent inviscid flows. The analytical relationship for the kinetic energy K, dK/dt = 0, with t as the dimensionless time, is utilized to validate the OpenFOAM results. For the viscous flow case, the TGV flow in a three-dimensional periodic cubic domain is adopted, and its turbulence kinetic energy distribution is compared with that obtained by a spectral method to examine the analysis. The OpenFOAM-based analysis exhibits energy conservation error in flows that should ideally conserve energy. For the two-dimensional flow, this error decreases with increasing grid resolution N. However, in the three-dimensional flow, the error does not improve even with higher N. In the three-dimensional TGV flow, the turbulence kinetic energy predicted by OpenFOAM exhibits a strong agreement with that from the spectral method when a standard constant value of the Smagorinsky model is employed and the mesh is sufficiently refined. Conversely, for a condition of relatively coarse mesh, the decay characteristics of turbulent kinetic energy deviate from those of the spectral method, and a higher constant value of the Smagorinsky model than the default value becomes necessary to reproduce comparable results. These results suggests that even in LES simulations where highly accurate conservation laws are not satisfied, adjusting the model constants so that the predicted values match experimental or numerical reference data can improve the apparent reliability of the turbulent kinetic energy in the decaying turbulence. en-copyright= kn-copyright= en-aut-name=SUZUKIHiroki en-aut-sei=SUZUKI en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TANAKAKento en-aut-sei=TANAKA en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KOUCHIToshinori en-aut-sei=KOUCHI en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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= en-keyword=Turbulent flows kn-keyword=Turbulent flows en-keyword=Numerical simulation kn-keyword=Numerical simulation en-keyword=Large-eddy simulation kn-keyword=Large-eddy simulation en-keyword=Energy conservation kn-keyword=Energy conservation en-keyword=Decaying turbulence kn-keyword=Decaying turbulence END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=3 article-no= start-page=179 end-page=187 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250901 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis and applications of porous carbonaceous materials with inherited molecular structural features from the precursor molecules en-subtitle= kn-subtitle= en-abstract= kn-abstract=The carbonization of organic crystalline materials, such as metal organic frameworks and covalent organic frameworks, has emerged as a promising approach for producing functional porous carbonaceous materials. However, both the chemically defined long-term ordered structures and the local chemical structures derived from these precursor materials are generally lost, resulting in amorphous carbons. As a result, controlling the molecular-level structure of nanoporous carbons remains a significant challenge. We report a new bottom-up synthesis approach for porous carbons with a molecular-level design, involving the carbonization of well-designed precursor molecules by thermal polymerization. Among the resulting carbons, ordered carbonaceous frameworks, which contain a high-density of regularly aligned single-atomic metal species, have been identified as promising platforms for single-atom catalysts. This approach also enables the synthesis of various three-dimensional porous carbons that reflect the structural features of their precursor molecules. Recent progress in the synthesis and applications of porous carbons derived from molecular precursors is summarized, highlighting their potential for the development of functional materials. en-copyright= kn-copyright= en-aut-name=ChidaKoki en-aut-sei=Chida en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshiTakeharu en-aut-sei=Yoshi en-aut-mei=Takeharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=KamiyaKazuhide en-aut-sei=Kamiya en-aut-mei=Kazuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakamotoRyota en-aut-sei=Sakamoto en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TaniFumito en-aut-sei=Tani en-aut-mei=Fumito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OgoshiTomoki en-aut-sei=Ogoshi en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishiharaHirotomo en-aut-sei=Nishihara en-aut-mei=Hirotomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Institute of Multidisciplinary Research for Advanced Materials, Tohoku University kn-affil= affil-num=2 en-affil=Institute of Multidisciplinary Research for Advanced Materials, Tohoku University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Research Center for Solar Energy Chemistry, Graduate School of Engineering Science, The University of Osaka kn-affil= affil-num=5 en-affil=Department of Chemistry, Graduate School of Science, Tohoku University kn-affil= affil-num=6 en-affil=Institute for Materials Chemistry and Engineering, Kyushu University kn-affil= affil-num=7 en-affil=Department of Synthetic Chemistry and Biological Chemistry, Graduate School of Engineering, Kyoto University kn-affil= affil-num=8 en-affil=Institute of Multidisciplinary Research for Advanced Materials, Tohoku University kn-affil= en-keyword=Ordered carbonaceous frameworks (OCFs) kn-keyword=Ordered carbonaceous frameworks (OCFs) en-keyword=Porous carbon materials kn-keyword=Porous carbon materials en-keyword=Single-atom catalysts (SACs) kn-keyword=Single-atom catalysts (SACs) en-keyword=Catalyst supports kn-keyword=Catalyst supports 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= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260219 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tabtoxin biosynthetic gene cluster in Pseudomonas syringae pv. tabaci 6605 genomic island 1 (GI-1Pta6605) is required for severe disease symptoms en-subtitle= kn-subtitle= en-abstract= kn-abstract=One of the genomic islands in Pseudomonas syringae pv. tabaci 6605 (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=183 cd-vols= no-issue= article-no= start-page=111902 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=Monitoring postharvest water loss in eggplants (Solanum melongena L.) using UV-induced fluorescence imaging and multivariate analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Eggplant (Solanum melongena L.) is susceptible to significant postharvest losses primarily due to water loss during storage, which affects market quality by causing texture and glossiness degradation. We investigated whether UV-induced fluorescence imaging and EEM (Excitation-Emission Matrix) fluorescence spectroscopy can non-destructively monitor WL under four storage regimes (10 °C/95 % RH, 20 °C/95 % RH, 20 °C/75 % RH, 10 °C/75 % RH). EEMs exhibited three regions; a 365/420 nm blue emission increased most under warm, low-humidity storage and is consistent with phenolic/lignin-related fluorescence. Side-view fluorescence (FL) images showed progressive blue-white emission and surface textural changes that tracked gravimetric water loss (WL). A PLSR model using combined color and texture features from FL and reflectance (CL) images achieved R2CV = 0.88 (RMSECV = 3.47 %) with only six features. To test a minimal predictor, we fit an Analysis of Covariance (ANCOVA) using Day-1 FL MeanBlue as a covariate and storage category as a factor with Leave One Out Cross-validation (LOOCV); this forecasted cumulative WL with R2LOOCV = 0.92 and MAE = 1.88 %. Importantly, this ANCOVA model using Day-1 blue-band fluorescence as a covariate was predictive only under 20 °C/75 % RH; under the other conditions, its contribution was weak. Linear Discriminant Analysis (LDA) and Support Vector Machine (SVM) models achieved accuracies of 94.4 % and 85.2 %, respectively, in differentiating storage conditions. These results support low-cost FL imaging as a practical tool to monitor WL and storage stress. en-copyright= kn-copyright= en-aut-name=RotichVincent en-aut-sei=Rotich en-aut-mei=Vincent kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GaoTianqi en-aut-sei=Gao en-aut-mei=Tianqi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=PrempreePanintorn en-aut-sei=Prempree en-aut-mei=Panintorn kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HayashiTakahiro en-aut-sei=Hayashi en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NambaKazuhiko en-aut-sei=Namba en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MontaMitsuji en-aut-sei=Monta en-aut-mei=Mitsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishimotoMotomi en-aut-sei=Nishimoto en-aut-mei=Motomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KondoNaoshi en-aut-sei=Kondo en-aut-mei=Naoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Laboratory of Biosensing Engineering, Graduate School of Agriculture, Kyoto University kn-affil= affil-num=2 en-affil=Laboratory of Biosensing Engineering, Graduate School of Agriculture, Kyoto University kn-affil= affil-num=3 en-affil=Laboratory of Biosensing Engineering, Graduate School of Agriculture, Kyoto University kn-affil= affil-num=4 en-affil=Laboratory of Biosensing Engineering, Graduate School of Agriculture, Kyoto 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= affil-num=7 en-affil=Technology and Innovation Center, Daikin Industries, Ltd. kn-affil= affil-num=8 en-affil=Laboratory of Biosensing Engineering, Graduate School of Agriculture, Kyoto University kn-affil= en-keyword=Eggplant kn-keyword=Eggplant en-keyword=Fluorescence spectroscopy kn-keyword=Fluorescence spectroscopy en-keyword=UV-Induced imaging kn-keyword=UV-Induced imaging en-keyword=Water loss kn-keyword=Water loss en-keyword=Postharvest quality kn-keyword=Postharvest quality en-keyword=Non-destructive assessment kn-keyword=Non-destructive assessment END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=16 article-no= start-page=9663 end-page=9677 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251011 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of sulfation for cellulose pulp to change its fiber morphology and appearance to transparent in water en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cellulose pulp (CP) is composed mainly of cellulose which is one of the most useful and sustainable natural polymers. Cellulose-based materials, such as completely dispersed nanofibers and water-soluble cellulose, are transparent in water. Additionally, chemical modification of CP has been employed as a pretreatment for the preparation of nanofibers and to impart absorption properties derived from anionic functional groups. However, little is known about chemically modified CPs comprising micron-scale fibers that are transparent in water.In this study, we synthesized transparent sulfated cellulose pulp (TSCP) that exhibits good dispersion stability, high transparency in water, and highly swollen fiber structures. The sulfation method involved heating sulfamic acid and urea supported on CP. TSCP synthesized using a sulfamic acid amount relative to CP (Q) of 18.5, a molar ratio of urea to sulfamic acid (R) of 0.80, and a reaction temperature of 140 °C exhibited the highest total light transmittance (94.7%) in water, a degree of polymerization (535), and amount of sulfate groups (1.73 mmol/g). Polarization microscopy confirmed that most TSCP fibers swelled in water along the fiber width direction. The structure of hydrous-state TSCP was further confirmed using low-vacuum scanning electron microscopy. The maximum fiber width of the swollen TSCP reached 122 μm, which was approximately six times than that of CP. The crystallinity was equivalent to that of the original CP with a Cellulose I-type crystalline structure. This transparent, hydrous-state TSCP, comprising predominantly swollen CP fibers, demonstrates potential for applications as a transparent material. en-copyright= kn-copyright= en-aut-name=NishimuraAyato en-aut-sei=Nishimura en-aut-mei=Ayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UchidaTetsuya en-aut-sei=Uchida en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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= en-keyword=Cellulose pulp kn-keyword=Cellulose pulp en-keyword=Sulfation kn-keyword=Sulfation en-keyword=Transparent kn-keyword=Transparent en-keyword=Swollen fiber structure kn-keyword=Swollen fiber structure en-keyword=Microscopy kn-keyword=Microscopy en-keyword=Refractive index kn-keyword=Refractive index END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=4591 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260106 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Calcium ions play a critical role in calcification of Corynebacterium matruchotii en-subtitle= kn-subtitle= en-abstract= kn-abstract=Dental calculus is a hardened deposit composed of calcium phosphate precipitated within dental plaque. While the involvement of dental calculus in the progression of periodontal disease is well established, many aspects of its formation process remain poorly understood. In this study, we focused on Corynebacterium matruchotii, a key bacterium involved in dental calculus formation, and investigated the role of calcium ions in calcification, as well as the associated internal and external changes in the bacterium through long-term observation. In the absence of calcium ions, no intracellular calcification was observed, and the lipid bilayer with the formation of holes in bacterial body was evident. In contrast, in the presence of calcium ions, lipid bilayer remained intact, and intracellular needle- and plate- like crystals were formed. Furthermore, calcified C. matruchotii showed increased flocculation compared to non-calcified C. matruchotii. These results indicate that the influx of calcium ions is essential for intracellular calcification. Calcium ions entry appears to reinforce the integrity of the lipid bilayer, providing a stable intracellular environment conductive to calcification. Moreover, calcified C. matruchotii may contribute to the nucleation of dental calculus by forming aggregates composed of both bacterial components and calcified material. en-copyright= kn-copyright= en-aut-name=OharaNaoko en-aut-sei=Ohara en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OgawaMidori en-aut-sei=Ogawa en-aut-mei=Midori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=TosaIkue en-aut-sei=Tosa en-aut-mei=Ikue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OnoSerina en-aut-sei=Ono en-aut-mei=Serina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SaitoMitsumasa en-aut-sei=Saito en-aut-mei=Mitsumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OharaNaoya en-aut-sei=Ohara en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Operative Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Microbiology, School of Medicine, University of Occupational and Environmental Health kn-affil= affil-num=3 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Microbiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Operative Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Microbiology, School of Medicine, University of Occupational and Environmental Health kn-affil= affil-num=7 en-affil=Department of Oral Microbiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Calcification kn-keyword=Calcification en-keyword=Corynebacterium matruchotii kn-keyword=Corynebacterium matruchotii en-keyword=Dental calculus kn-keyword=Dental calculus en-keyword=Calcium ions kn-keyword=Calcium ions END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=2 article-no= start-page=444 end-page=451 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=Interactive Effects of Maximum Daytime and Minimum Nighttime Temperatures on Spinach Growth and Physiological Characteristics en-subtitle= kn-subtitle= en-abstract= kn-abstract=High temperatures restrict spinach growth, and the plant’s growth and physiological responses to heat remain poorly understood. It remains unclear whether high daytime or elevated nighttime temperatures have a more negative impact on spinach growth. In addition, the interaction effect of maximum daytime and minimum nighttime temperatures on spinach growth remains unknown. This study was conducted to address these issues. Spinach was grown in controlled environments under four temperature treatments: 30 and 20 °C (T30/20), 30 and 25 °C (T30/25), 35 and 20 °C (T35/20), and 35 and 25 °C (T35/25). These treatments represent the maximum daytime temperature and minimum nighttime temperature, respectively, and were maintained for 45 days. Plant growth characteristics were monitored, and the physiological responses to temperature regimes were assessed. The results show that compared with T30/20, dry matter production decreased by 15.4% with increased nighttime temperature (T30/25), decreased by 42.3% with increased daytime temperature (T35/20), and decreased by 57.7% when both daytime and nighttime temperatures were increased (T35/25). However, there was no statistically significant interaction effect (P > 0.05) between daytime maximum and nighttime minimum temperatures on plant biomass production variables. In comparison with T30/20, the T35/25 treatment increased significantly plant stomatal conductance, stomatal apertures, transpiration rate, and leaf temperature during heat waves. The T35/25 treatment also decreased the quantum efficiency in light compared with the other treatments. Plant biomass production did not improve with the T35/20 and T35/25 treatments, likely as a result of a decoupling of photosynthesis and stomatal conductance during heat waves. Overall, these results reveal that maximum daytime and minimum nighttime temperatures exert additive effects on spinach growth. en-copyright= kn-copyright= en-aut-name=SambaNethone en-aut-sei=Samba en-aut-mei=Nethone kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AkasakaHisao en-aut-sei=Akasaka en-aut-mei=Hisao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 ORCID= en-aut-name=Hikawa-EndoMinori en-aut-sei=Hikawa-Endo en-aut-mei=Minori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyamaYoko en-aut-sei=Miyama en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Faculty of Food and Agricultural Sciences, Fukushima University kn-affil= affil-num=2 en-affil=The United Graduate School of Agricultural Sciences, Iwate University, Iwate, 020-8550, Japan; and Iwate Agricultural Research Center, Kenpoku Agricultural Research Institute kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Faculty of Food and Agricultural Sciences, Fukushima University, Fukushima, 960-1296, Japan; and The United Graduate School of Agricultural Sciences, Iwate University kn-affil= en-keyword=photosynthesis kn-keyword=photosynthesis en-keyword=quantum efficiency kn-keyword=quantum efficiency en-keyword=stomatal aperture kn-keyword=stomatal aperture en-keyword=stomatal conductance kn-keyword=stomatal conductance en-keyword=transpiration kn-keyword=transpiration 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=14 cd-vols= no-issue= article-no= start-page=17960 end-page=17970 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=FEM-Based Design and Characterization of a Millimeter-Scale Piezoelectric Resonance Force Sensor en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper presents a millimeter-scale piezoelectric effect-based force sensor that uses the change in its resonant frequency as the detection principle for high sensitivity and a wide measurement range. Such characteristics are suited for robot hand applications that not only detect small forces but also handle large payloads. We develop a methodology to estimate the relationship between applied force and resonant frequency shift by combining classical contact theory and finite element method (FEM) analysis. Although this relationship is non-linear, the designability of sensitivity and measurement range is demonstrated by the simulation. The simulation results based on the method are verified, showing good agreement with the experimental results. The static characteristics, including sensitivity, standard deviation, and resolution, are evaluated using prototype sensors with characteristic lengths ranging from 1 mm to 4 mm. The 4-mm model has a measurement range of 77 mN to 300 N, and the smallest model, which is one of the smallest force sensors suitable for practical implementation, has a measurement range of 9 mN to 20 N. en-copyright= kn-copyright= en-aut-name=YamazakiAoto en-aut-sei=Yamazaki en-aut-mei=Aoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AkidukiTakuma en-aut-sei=Akiduki en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HonnaAtsuo en-aut-sei=Honna en-aut-mei=Atsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KitazakiMichiteru en-aut-sei=Kitazaki en-aut-mei=Michiteru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MashimoTomoaki en-aut-sei=Mashimo en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Mechanical Engineering, Toyohashi University of Technology kn-affil= affil-num=2 en-affil=Department of Mechanical Engineering, Toyohashi University of Technology kn-affil= affil-num=3 en-affil=Riccoh Company Ltd. kn-affil= affil-num=4 en-affil=Department of Computer Science and Engineering, Toyohashi University of Technology kn-affil= affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Force sensors kn-keyword=Force sensors en-keyword=piezoelectric effect kn-keyword=piezoelectric effect en-keyword=resonators kn-keyword=resonators en-keyword=transducers kn-keyword=transducers en-keyword=ultrasonics kn-keyword=ultrasonics 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 Å and 2.17 Å, 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=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 < 0.0001). Overall, 54% of respondents were engaged in teaching students or early-career pediatric rheumatologists, while 43% were involved in clinical or basic research, most commonly focusing on juvenile idiopathic arthritis and systemic lupus erythematosus. Collectively, respondents were responsible for the care of 1,677 children with pediatric rheumatic diseases. While all respondents reported willingness to contribute to pediatric rheumatology at the regional level, 94% and 71% reported willingness to contribute at the national and global levels, respectively.
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=Gaseous CO2 electrolysis: latest advances in electrode and electrolyzer technologies toward abating CO2 emissions en-subtitle= kn-subtitle= en-abstract= kn-abstract=The conversion of CO2 into multicarbon (C2+) products via electrochemical reduction is considered a key technology for the sustainable production of fuels and chemicals. The performance of high-rate gaseous CO2 electrolysis is governed by interrelated factors such as the electrocatalysts, electrodes, electrolytes, and cell architectures. Despite the intensive focus on catalyst research, systematic studies addressing the other components remain scarce, leaving critical gaps in our understanding toward achieving higher performance in CO2 electrolysis systems. The nanoscale design of catalyst surface electronic structures and the macroscale design of electrodes and electrolyzer architectures both influence the overall activity of the electrochemical system. In designing macroscale components, it is necessary to establish benchmarks based on a comprehensive evaluation of CO2 emissions for the entire electrolysis process, because these parameters are directly linked to output metrics such as current density and cell voltage under practical operating conditions. This review summarizes recent advances in electrodes and electrolyzers, and through life-cycle assessment (LCA), evaluates key performance indicators (KPIs) for achieving negative emissions and assesses the current technology readiness of CO2 electrolysis. en-copyright= kn-copyright= en-aut-name=KamiyaKazuhide en-aut-sei=Kamiya en-aut-mei=Kazuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakasoneSora en-aut-sei=Nakasone en-aut-mei=Sora kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KuriharaRyo en-aut-sei=Kurihara en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueAsato en-aut-sei=Inoue en-aut-mei=Asato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IrieHazuki en-aut-sei=Irie en-aut-mei=Hazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakahataShoko en-aut-sei=Nakahata en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=TaniguchiSatoshi en-aut-sei=Taniguchi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NguyenThuy T.

In this study, we conducted a literature search and systematic review focusing on the outcomes after surgery for older cancer patients.
Methods: Literature focusing on surgical treatment for older cancer patients was extracted from Japanese clinical practice guidelines for gastric cancer, lung cancer, colorectal cancer, liver cancer, and gynecological cancers (uterine body, uterine cervix, ovary, and external genitalia and vagina). Outcomes were reviewed, and committee members determined the strength of evidence on a four-point scale (A to D), with A being the highest and D being the lowest.
Results: Older cancer patients tend to have a higher incidence of postoperative complications and postoperative syndromes, and their expected survival is generally shorter compared to non-older patients. When extensive surgeries such as para-aortic lymph node dissection and/or resection with other organs are performed for older cancer patients, the postoperative mortality rates tend to increase compared to non-older patients.
Conclusion: Surgical treatments for older cancer patients tend to result in higher morbidity even when the patients are in good health status. Nevertheless, there is still a possibility that a certain fraction of the patients achieve treatment outcomes comparable to those of non-older patients. Therefore, surgical indication and procedure for older cancer patients should be carefully determined based on surgical invasiveness and patient tolerability. en-copyright= kn-copyright= en-aut-name=TanakaChie en-aut-sei=Tanaka en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OfuchiTakashi en-aut-sei=Ofuchi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=InoueDaisuke en-aut-sei=Inoue en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugimotoKen en-aut-sei=Sugimoto en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MurofushiKeiko en-aut-sei=Murofushi en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkuyamaToru en-aut-sei=Okuyama en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanukiShigeaki en-aut-sei=Watanuki en-aut-mei=Shigeaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ImamuraChiyo en-aut-sei=Imamura en-aut-mei=Chiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SakaiDaisuke en-aut-sei=Sakai en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SakuraiNaomi en-aut-sei=Sakurai en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=WatanabeKiyotaka en-aut-sei=Watanabe en-aut-mei=Kiyotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TamuraKazuo en-aut-sei=Tamura en-aut-mei=Kazuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=SaekiToshiaki en-aut-sei=Saeki en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=IshiguroHiroshi en-aut-sei=Ishiguro en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Nagoya University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Surgery, Kyushu University Beppu Hospital kn-affil= affil-num=3 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, University of Fukui kn-affil= affil-num=5 en-affil=Department of General Geriatric Medicine, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Division of Radiation Oncology, Department of Radiology, Tokyo Metropolitan Cancer and Infectious Diseases Center Komagome Hospital kn-affil= affil-num=7 en-affil=Department of Psychiatry/Palliative Care Center, Nagoya City University West Medical Center kn-affil= affil-num=8 en-affil=National Center for Global Health and Medicine, National College of Nursing kn-affil= affil-num=9 en-affil=Advanced Cancer Translational Research Institute, Showa University kn-affil= affil-num=10 en-affil=Department of Frontier Science for Cancer and Chemotherapy, Osaka University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Cancer Solutions Co.

Euryhaline elasmobranchs face the severest water-influx potential in fresh water (FW), as they retain high concentrations of urea even in hypotonic environments. To elucidate how they overcome this osmotic challenge, we assessed urine output in conscious euryhaline red stingrays (Hemitrygon akajei). Following acclimation to 5% diluted seawater, the stingrays increased urinary output by 87-fold—the greatest change observed in vertebrates—partly due to 6.8-fold increase in glomerular filtration rate (GFR). In the nephron, expressions of Aquaporin-1 (Aqp1), Aqp3, and Aqp15 were strongly downregulated in FW, indicating that tubular diuresis bridges the gap between GFR and final urine volume. Meanwhile, FW-acclimation upregulated Aqp1 and Aqp4 in the distinct bundle structure, which promotes urea reabsorption. Euryhaline elasmobranchs resolve the huge osmotic challenge of FW by excreting massive amounts of water and retaining osmolytes including urea through coordinated regulation of GFR and Aqp expressions. en-copyright= kn-copyright= en-aut-name=AburataniNaotaka en-aut-sei=Aburatani en-aut-mei=Naotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakagiWataru en-aut-sei=Takagi en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WongMarty Kwok-Shing en-aut-sei=Wong en-aut-mei=Marty Kwok-Shing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OgawaNobuhiro en-aut-sei=Ogawa en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KurakuShigehiro en-aut-sei=Kuraku en-aut-mei=Shigehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SatoMana en-aut-sei=Sato en-aut-mei=Mana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaitoKazuhiro en-aut-sei=Saito en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=GodoWaichiro en-aut-sei=Godo en-aut-mei=Waichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SakamotoTatsuya en-aut-sei=Sakamoto en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HyodoSusumu en-aut-sei=Hyodo en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Atmosphere and Ocean Research Institute, The University of Tokyo kn-affil= affil-num=2 en-affil=Atmosphere and Ocean Research Institute, The University of Tokyo kn-affil= affil-num=3 en-affil=Atmosphere and Ocean Research Institute, The University of Tokyo kn-affil= affil-num=4 en-affil=Atmosphere and Ocean Research Institute, The University of Tokyo kn-affil= affil-num=5 en-affil=Department of Genomics and Evolutionary Biology, National Institute of Genetics kn-affil= affil-num=6 en-affil=Department of Genomics and Evolutionary Biology, National Institute of Genetics kn-affil= affil-num=7 en-affil=Ushimado Marine Institute, Faculty of Science, Okayama University kn-affil= affil-num=8 en-affil=Ushimado Marine Institute, Faculty of Science, Okayama University kn-affil= affil-num=9 en-affil=Ushimado Marine Institute, Faculty of Science, Okayama University kn-affil= affil-num=10 en-affil=Atmosphere and Ocean Research Institute, The University of Tokyo kn-affil= en-keyword=Zoology kn-keyword=Zoology en-keyword=Biochemistry kn-keyword=Biochemistry en-keyword=Animal Physiology kn-keyword=Animal Physiology 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=20260303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Towards place-responsive climate change education: Mongolian primary teachers’ pedagogical judgement across urban and rural contexts en-subtitle= kn-subtitle= en-abstract= kn-abstract=Climate change education (CCE) in primary schools is increasingly recognised as essential, yet how teachers interpret and enact CCE across diverse local contexts remains underexplored. This study examines how Mongolian primary school teachers working with students aged 6–11 in urban and rural contexts interpret and teach climate change, with particular attention to the role of place. Drawing on semi-structured interviews with 20 teachers across contrasting contexts, the study explores how environmental, cultural, and institutional conditions shape teachers’ pedagogical interpretations and classroom practices. Data were analysed using reflexive thematic analysis, informed by conceptual frameworks that position place as an active mediator of teaching and learning. Findings show that rural teachers frequently integrated traditional ecological knowledge and lived environmental experience to connect global climate processes with locally observable ecological change, emphasising livelihood impacts and intergenerational ecological memory. Urban teachers, by contrast, framed climate change through anthropogenic pressures such as air pollution, waste, and infrastructure constraints, foregrounding feasible individual actions within everyday school contexts. Across both settings, teachers exercised place-responsive pedagogical judgement by selectively adapting climate content to local realities while navigating curriculum constraints and workload pressures. The study contributes a place-responsive account of teachers’ pedagogical judgement in CCE, demonstrating how place functions not only as context but as a condition shaping pedagogical feasibility. en-copyright= kn-copyright= en-aut-name=GerelkhuuShinetsetseg en-aut-sei=Gerelkhuu en-aut-mei=Shinetsetseg kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Fiel’ardhKhalifatulloh en-aut-sei=Fiel’ardh en-aut-mei=Khalifatulloh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiHiroki en-aut-sei=Fujii en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YembuuBatchuluun en-aut-sei=Yembuu en-aut-mei=Batchuluun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DembereldorjUuriintuya en-aut-sei=Dembereldorj en-aut-mei=Uuriintuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Education, Okayama University kn-affil= affil-num=4 en-affil=Geography Department, Mongolian National University of Education kn-affil= affil-num=5 en-affil=Lifelong Learning and Distance Education Department, Mongolian National University of Education kn-affil= en-keyword=Climate change education kn-keyword=Climate change education en-keyword=place-responsive education kn-keyword=place-responsive education en-keyword=primary school teachers kn-keyword=primary school teachers en-keyword=pedagogical judgement kn-keyword=pedagogical judgement en-keyword=traditional ecological knowledge kn-keyword=traditional ecological knowledge en-keyword=urban–rural contexts kn-keyword=urban–rural contexts en-keyword=Mongolia kn-keyword=Mongolia 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=133 cd-vols= no-issue= article-no= start-page=111546 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=Robotic pancreatoduodenectomy for a giant duodenal leiomyoma: A case report and literature review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Duodenal leiomyomas are rare mesenchymal tumors. To date, several studies have reported on the safety and feasibility of surgical intervention for duodenal leiomyomas. However, minimally invasive surgery has rarely been performed in cases with duodenal leiomyomas. Herein, we present a case of a giant duodenal leiomyoma successfully treated with robotic pancreatoduodenectomy (RPD).
Presentation of case: A 74-year-old man was referred to our hospital with a 6.5 cm duodenal tumor accompanied by gastrointestinal bleeding. The tumor was located in the second portion of the duodenum. Considering the tumor size and location, RPD was performed. Using the mesenteric Kocker maneuver, the posterior side of the duodenum was safely dissected, and the tumor was resected. The operative time was 373 min, with an estimated blood loss of 10 mL. The patient was followed up for 7 months with no recurrence.
Discussion: To the best of our knowledge, this is the first to highlight the clinicopathological findings of a patient with duodenal leiomyoma undergoing RPD. To date, there have been 19 cases, including our case, reporting surgically treated duodenal leiomyoma. Treatment strategies should be decided depending on tumor characteristics, including the size, location, and histology of the tumor.
Conclusion: We present a rare case of a giant duodenal leiomyoma that was successfully treated with RPD. Minimally invasive surgery can be safe and an alternative for the treatment of large duodenal tumors. en-copyright= kn-copyright= en-aut-name=DoitaSusumu en-aut-sei=Doita en-aut-mei=Susumu 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=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=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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= en-keyword=Duodenal leiomyomas kn-keyword=Duodenal leiomyomas en-keyword=Robotic surgery kn-keyword=Robotic surgery en-keyword=Pancreatoduodenectomy kn-keyword=Pancreatoduodenectomy 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.

EGFR-Tyrosine Kinase Inhibitor After Disease Progression Following Gefitinib Induction and Chemoradiotherapy in EGFR-Mutant Stage III Non-small Lung Cancer: An Efficacy and Safety Analysis of the LOGIK0902/OLCSG0905 Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and objective: We had previously conducted a phase II study (LOGIK0902/OLCSG0905 study) involving the eight-week administration of gefitinib, followed by cisplatin-based chemoradiotherapy, to treat locally advanced, epidermal growth factor receptor (EGFR)-mutated, non-small cell lung cancer (NSCLC). Despite favorable overall survival outcomes, more than half of the patients relapsed after the protocol therapy, highlighting the need to clarify the clinical significance of retreatment with EGFR-tyrosine kinase inhibitors (TKIs). We investigated the efficacy and safety of EGFR-TKI retreatment after disease progression.
Materials and methods: We included 14 patients who relapsed after the protocol treatment and received any type of EGFR-TKI as post-progression treatment in this sub-analysis. We evaluated the efficacy and safety of retreatment with EGFR-TKI in these patients.
Results: Among the 14 patients, 11 (78.6%) responded to the induction of gefitinib in the treatment protocol. After relapse, 9/14 patients (64.3%) received gefitinib, 3/14 (21.4%) received afatinib, and 2/14 (14.3%) received erlotinib monotherapy, respectively. The median duration of post-progression EGFR-TKI treatment was 17.9 (0.7-45.5) months. The overall response rate (ORR) and disease control rate were 64.3% [9/14 patients; 95% confidence interval (CI): 35.1%-87.2%] and 85.7% (12/14 patients; 95% CI: 57.2%-98.2%), respectively. The median progression-free survival (PFS) and median survival durations after the initiation of EGFR-TKI retreatment were 11.8 months (95% CI: 5.7-20.7 months) and 47.4 months (95% CI: 31.8 months to not estimable), respectively. Adverse events were comparable to those previously reported.
Conclusions: Patients with disease progression after protocol therapy demonstrated sensitivity to retreatment with an EGFR-TKI, with acceptable safety. en-copyright= kn-copyright= en-aut-name=SaekiSho

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=3027 cd-vols= no-issue=1 article-no= start-page=012009 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=LES analysis to investigate a random-phase forcing scheme for steadying anisotropic turbulence fields en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study is to investigate the effect of phase randomization on forcing mechanisms that stabilize localized turbulence. A trigonometric forcing based on vector potential is combined with uniform random numbers to create a spatially homogeneous forcing field. The analysis is performed using large-eddy simulation (LES) with the Smagorinsky model as the subgrid scale model. The results demonstrate that steady flows are generated regardless of the presence of phase randomization, successfully forming isotropic turbulence. In contrast, for anisotropic turbulent fields, the addition of phase randomization reduces the degree of anisotropy, indicating a smoothing effect on the anisotropy of the flow. en-copyright= kn-copyright= en-aut-name=MinamiKoki en-aut-sei=Minami en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiHiroki en-aut-sei=Suzuki en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KouchiToshinori en-aut-sei=Kouchi en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaKento en-aut-sei=Tanaka en-aut-mei=Kento 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 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= END start-ver=1.4 cd-journal=joma no-vol=3027 cd-vols= no-issue=1 article-no= start-page=012008 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fundamental examination of coherent structure model prediction using vortex cores in a two-dimensional Taylor’s analytical solution en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study focuses on the possibility that flow around vortex tubes in turbulence may resemble laminar flow, and aims to describe the characteristics of turbulent fields using analytical solutions to the governing equations. In the two-dimensional analytical Taylor solution, the velocity and pressure fields are expressed by trigonometric functions, and a structure in which counter-rotating vortices are arranged in a grid pattern is demonstrated. This solution is used to verify the accuracy of numerical analyses and is expected to contribute to a simple yet unambiguous description of turbulent fields based on vortex structures. Predictions of sub-grid scale components and validation of a coherent structure model using invariants of the velocity gradient tensor are also performed. en-copyright= kn-copyright= en-aut-name=GongXuanyou en-aut-sei=Gong en-aut-mei=Xuanyou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiHiroki en-aut-sei=Suzuki en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KouchiToshinori en-aut-sei=Kouchi en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaKento en-aut-sei=Tanaka en-aut-mei=Kento 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 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= END start-ver=1.4 cd-journal=joma no-vol=115 cd-vols= no-issue= article-no= start-page=9 end-page=12 dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260301 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Soil nitrogen dynamics affected by the fine roots of canopy trees in Eastern Hokkaido, Japan kn-title=北海道東部の森林において林冠木の細根が土壌窒素動態に与える影響 en-subtitle= kn-subtitle= en-abstract= kn-abstract= Plants release mixtures of labile organic matter from their fine roots (root exudates) into the surrounding soil (rhizosphere). Partly due to the release of root exudates, microbial community structures and their activities within the rhizosphere differ significantly from those in other soil areas (bulk soil). Consequently, nutrient cycling processes, including nitrogen mineralization, are accelerated in the rhizosphere, facilitating nutrient acquisition by plants. This phenomenon, known as the rhizosphere effect, has been repeatedly reported in studies of herbaceous plants; however, the impact of canopy tree fine roots on soil nitrogen dynamics through the effect in forest ecosystems remains largely unknown. Here, I introduce our research investigating the root exudates and rhizosphere effects of the fine roots of canopy trees, Quercus crispula, and how these fine roots affect soil nitrogen dynamics. The quantity of root exudates varied daily rather than seasonally, with solar radiation having a strong and positive effect on the amounts. However, even after leaf fall, root exudation was observed. In the rhizosphere, specific bacterial communities were present regardless of season, while ectomycorrhizal fungal populations were higher than in the bulk soil only in summer. Extracellular enzymatic activity relating to nitrogen cycling was higher in the rhizosphere than in the bulk soil across seasons. Nitrogen uptake by the tree was likely lower in winter and spring, leading to labile nitrogen accumulation in the rhizosphere during these periods. On an annual basis, however, the impact of fine roots on apparent inorganic nitrogen dynamics was minor. These results suggest that the canopy tree, Q. crispula, accelerates soil nitrogen cycling through root exudation and rhizosphere effects, regardless of season, while the acceleration of the cycle and the utilization of available nitrogen are well-balanced annually, thereby avoiding unnecessary carbon investment. en-copyright= kn-copyright= en-aut-name=NakayamaMasataka en-aut-sei=Nakayama en-aut-mei=Masataka kn-aut-name=中山理智 kn-aut-sei=中山 kn-aut-mei=理智 aut-affil-num=1 ORCID= affil-num=1 en-affil=Course of Environmental Ecology kn-affil=環境生態学コース en-keyword=Quercus crispula kn-keyword=Quercus crispula en-keyword=root exudates kn-keyword=root exudates en-keyword=rhizosphere effect kn-keyword=rhizosphere effect en-keyword=nitrogen dynamics kn-keyword=nitrogen dynamics en-keyword=nitrogen uptake kn-keyword=nitrogen uptake END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=209 end-page=226 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= kn-title=Teaching and Learning:Japanese and International Student Collaboration in the Classroom en-subtitle= kn-subtitle= en-abstract= kn-abstract=This practical report introduces three intercultural collaborative trial classes designed to integrate Japanese and international students in first-year EFL classes.

Analysis indicates that interaction across diverse cultural and linguistic backgrounds fostered intercultural awareness while motivating Japanese learners to further develop their speaking skills. The findings support the value of collaborative, content-based activities for enhancing intercultural understanding. en-copyright= kn-copyright= en-aut-name=PUSINAAlexis en-aut-sei=PUSINA en-aut-mei=Alexis kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OTOSHIJunko en-aut-sei=OTOSHI en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Institute for Promotion of Education and Campus Life, Okayama University affil-num=2 en-affil= kn-affil=Institute for Promotion of Education and Campus Life, Okayama University en-keyword=collaborative learning kn-keyword=collaborative learning en-keyword=content and language integrated learning (CLIL) kn-keyword=content and language integrated learning (CLIL) en-keyword=intercultural understanding kn-keyword=intercultural understanding en-keyword=intercultural communication kn-keyword=intercultural communication END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=195 end-page=208 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=Examination of Accessible Outdoor Tourism Based on the Global Code of Ethics for Tourism:Practical Application of Outdoor Wheelchairs in World Natural Heritage Sites kn-title=世界観光倫理憲章を踏まえたアクセシブルアウトドアツーリズムの検討 ―世界自然遺産地域でのアウトドア型車椅子を用いた実践を通じて― en-subtitle= kn-subtitle= en-abstract=Promoting accessible outdoor tourism requires balancing conservation and protection with development.

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=120 end-page=128 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= kn-title=From The Odyssey to The Zahir:The Evolution of Penelopeia Across Time and Tradition en-subtitle= kn-subtitle= en-abstract= kn-abstract=The story of a man who leaves home and strives to return has become one of the most enduring narrative patterns in world literature and folklore. Across centuries and cultures, it has been retold in myths, epics, folktales, and modern fiction—the story of the homecoming hero who, after long absence and peril, finds his way back to the place and the person he once called his own. This study explores the persistence and transformation of this universal motif through a comparative reading of Homer’s The Odyssey and Paulo Coelho’s The Zahir. It examines the evolving image of the waiting wife—from Homer’s Penelopeia, emblem of chastity and endurance, to Coelho’s Esther, a modern woman of independence and choice. Despite differences in setting, voice, and moral vision, both works embody the same human longing: to return, to be recognized, and to rediscover love that endures time and change. Beneath their differences lies the same truth—the heart to which every journey, whether physical or spiritual, must ultimately return. en-copyright= kn-copyright= en-aut-name=KHALMIRZAEVASaida en-aut-sei=KHALMIRZAEVA en-aut-mei=Saida kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Faculty of General Education and Global Studies, Okayama University kn-affil= en-keyword=Homer kn-keyword=Homer en-keyword=The Odyssey kn-keyword=The Odyssey en-keyword=Paulo Coelho kn-keyword=Paulo Coelho en-keyword=The Zahir kn-keyword=The Zahir en-keyword=Penelopeia kn-keyword=Penelopeia END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=31 end-page=40 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=A Study of Participant Interaction in Online Volunteer Japanese Language Classes:Toward the Advancement of Community-Based Japanese Language Education kn-title=オンラインによるボランティア日本語教室における参加者間のインターアクションの分析 ―地域型日本語教育の実現に向けて― en-subtitle= kn-subtitle= en-abstract=This study investigates interactional dynamics within an online volunteer-based Japanese language classroom, with the aim of contributing to the development of a community-based instructional model. Employing the FLint system, the research analyzes the speech patterns and instructional behaviors of both supporters and learners in classroom settings characterized by community-oriented features. The analysis yielded the following findings: (1) the mean number of utterances produced by supporters was greater than that of learners; and (2) the average amount of indirect behavior in supporters’ utterances by slightly exceeded that of direct behavior. In the interactive style, supporters were observed to actively employ subcategories of indirect behaviors—such as questioning, using ideas of learners, and repeating learner responses—in order to scaffold the learners’ process of verbalizing their intended messages. kn-abstract= 本研究では,地域型日本語教育のモデル構築に向け,地域型の特徴を有する教室内での支援者および参加者の発話や教授行動の傾向を明らかにすべく,外国語相互作用分析システムを用い,オンラインによるボランティア教室におけるインターアクションの分析を行った。分析の結果,(1)支援者の平均発話数が学習者より多いこと,(2)支援者の発話における間接的行動の割合が直接的行動よりもやや高いことが示された。「おしゃべり型の教育」では,学習者が伝えたいことを言語化していくプロセスの中で,間接的行動の下位分類の「質問」「学習者の意図の利用」「学習者の回答の繰り返し」等を支援者が積極的に使用し支援していることが分かった。 en-copyright= kn-copyright= en-aut-name=SUESHIGEMiwa en-aut-sei=SUESHIGE en-aut-mei=Miwa kn-aut-name=末繁美和 kn-aut-sei=末繁 kn-aut-mei=美和 aut-affil-num=1 ORCID= affil-num=1 en-affil=Institute for Promotion of Education and Campus Life, Okayama University kn-affil=岡山大学教育推進機構 en-keyword=地域型日本語教育 kn-keyword=地域型日本語教育 en-keyword=おしゃべり型 kn-keyword=おしゃべり型 en-keyword=オンラインボランティア教室 kn-keyword=オンラインボランティア教室 en-keyword=F-システム kn-keyword=F-システム en-keyword=インターアクション kn-keyword=インターアクション END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue= article-no= start-page=106742 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202509 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Inscribed-type spherical speed reducer with uniform reduction ratio in all directions en-subtitle= kn-subtitle= en-abstract= kn-abstract=A spherical motor is an actuator that can generate rotational motion about all three orthogonal axes. However, it is difficult to obtain high output torque from most electromagnetic spherical motors, primarily due to limitations inherent in electromagnetic actuators, such as restricted magnetic force and thermal constraints. Since its torque cannot be increased using planar gears, spherical speed reducers that transmit rotational torque along three orthogonal axes through sphere-to-sphere contact are required. One major limitation of conventional spherical speed reducers is that their size increases significantly as the reduction ratio becomes higher. To address this issue, we propose a novel inscribed-type spherical speed reducer, in which the deceleration mechanism is integrated within the output sphere. This configuration enables a more compact design, reducing the overall size to approximately half that of conventional designs. To predict the angular velocity and transmitted torque, theoretical models for the rotation and torque transmission of the speed reducer were developed. According to the proposed model, the reduction ratio of the spherical speed reducer is 1/3. To verify the validity of these models, experiments were conducted to measure angular velocity and torque. The theoretical results agreed well with the experimental results. In addition, the theoretical torque exhibited an average relative error of 1.63 % compared to the experimental result. Therefore, it was confirmed that the rotation and torque transmission models were valid. These results demonstrate that a reduction ratio can be obtained in all directions of the 3-DOF of the spherical speed reducer, unlike conventional 1-DOF reducers. en-copyright= kn-copyright= en-aut-name=NaramuraSeiya en-aut-sei=Naramura en-aut-mei=Seiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TonegawaKoichi en-aut-sei=Tonegawa en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimookaSo en-aut-sei=Shimooka en-aut-mei=So kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YanoTomoaki en-aut-sei=Yano en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GofukuAkio en-aut-sei=Gofuku en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KasashimaNagayoshi en-aut-sei=Kasashima en-aut-mei=Nagayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KamegawaTetsushi en-aut-sei=Kamegawa en-aut-mei=Tetsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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 Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Okayama Prefectural University kn-affil= affil-num=6 en-affil=National Institute of Advanced Industrial Science and Technology kn-affil= affil-num=7 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Inscribed-type spherical speed reducer kn-keyword=Inscribed-type spherical speed reducer en-keyword=Rotation and torque transmission kn-keyword=Rotation and torque transmission en-keyword=Friction kn-keyword=Friction en-keyword=Spherical motor kn-keyword=Spherical motor en-keyword=Three-axis rotation kn-keyword=Three-axis rotation END start-ver=1.4 cd-journal=joma no-vol=779 cd-vols= no-issue= article-no= start-page=110775 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=Comparison of bioavailability of quercetin and its structural analogs in mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Flavonoids are thought to provide beneficial effects on health. However, there are still uncertainties regarding their bioavailability. In this study, we investigated the bioavailability of 6 flavonoids, galangin, kaempferol, quercetin, myricetin, fisetin, and luteolin, by oral administration to mice. Analysis of plasma concentrations of free flavonoids after deconjugation by LC-MS/MS revealed that all flavonoids were rapidly absorbed after administration. Among 6 flavonoids, kaempferol and fisetin showed high absorbed amounts in blood plasma. With the LogP value of the two flavonoids as the maximum value, the amount absorbed decreased for both lower and higher LogP values. The results of the tissue distribution of galangin, kaempferol, and quercetin suggested that the order of fastest movement from the stomach to the small intestine was kaempferol > quercetin > galangin. In addition, the amount of kaempferol and quercetin distributed in the liver was greater than that of galangin. These results suggest that the bioavailability of flavonoids varies with the slight structural differences, possibly due to differences in their rapid accessibility to the small intestine that is the primary site of absorption and metabolism within the body. en-copyright= kn-copyright= en-aut-name=MaedaNozomi en-aut-sei=Maeda en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HashimotoAtsushi en-aut-sei=Hashimoto en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoritaRyosei en-aut-sei=Morita en-aut-mei=Ryosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MunemasaShintaro en-aut-sei=Munemasa en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurataYoshiyuki en-aut-sei=Murata en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakamuraYoshimasa en-aut-sei=Nakamura en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraToshiyuki en-aut-sei=Nakamura en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Flavonoid kn-keyword=Flavonoid en-keyword=Bioavailability kn-keyword=Bioavailability en-keyword=Distribution kn-keyword=Distribution END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=1 article-no= start-page=57 end-page=66 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=Piezo1-mediated mechanotransduction in cementocytes via protein kinase B and p38 mitogen-activated protein kinase signaling en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/purpose: Cementocytes, terminally differentiated cells embedded within cellular cementum, are morphologically similar to osteocytes; however, their mechanosensory function remains poorly understood. This study aimed to investigate whether Piezo1, a mechanosensitive ion channel, contributes to the regulation of osteo/cementogenic gene expression in murine cementocyte-like IDG-CM6 cells.
Materials and methods: IDG-CM6 cells were subjected to cyclic stretch or treated with Piezo1-specific agonist Yoda1 or antagonist GsMTx4. Expression levels of osteo/cementogenic genes (Wnt1, Sost, Opg) and protein levels were analyzed. The involvement of intracellular signaling pathways was assessed using pharmacological inhibitors targeting mitogen-activated protein kinase and protein kinase B (PKB/AKT) pathways.
Results: Cyclic stretch upregulated Wnt1 and Opg, and downregulated Sost expression, without altering Piezo1 expression, suggesting an enhanced osteo/cementogenic potential. These effects were abolished by GsMTx4 and closely mimicked by Yoda1 stimulation. The Yoda1-induced gene expression changes were transient and diminished after withdrawal. Inhibitor experiments confirmed that Piezo1-mediated gene expression is modulated primarily through the AKT and p38 signaling pathways. Phosphorylation of AKT and p38 was rapidly induced by cyclic stretch.
Conclusion: Our findings demonstrate that Piezo1 functions as a mechanosensor in cementocytes, modulating the expression of osteo/cementogenic genes via the AKT and p38 pathways. This study provides new insight into the molecular mechanisms of cementocyte mechanotransduction and may inform strategies for periodontal regeneration and orthodontic treatment. en-copyright= kn-copyright= en-aut-name=XiongKaixin en-aut-sei=Xiong en-aut-mei=Kaixin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakisakaYukihiko en-aut-sei=Sakisaka en-aut-mei=Yukihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TenkumoTaichi en-aut-sei=Tenkumo en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NemotoEiji en-aut-sei=Nemoto en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaruyamaKentaro en-aut-sei=Maruyama en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MuhammadFaisal en-aut-sei=Muhammad en-aut-mei=Faisal kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuzukiShigeki en-aut-sei=Suzuki en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TadaHiroyuki en-aut-sei=Tada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamadaSatoru en-aut-sei=Yamada en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Stomatology, Chengdu Integrated TCM and Western Medicine Hospital (Chengdu First People’s Hospital) kn-affil= affil-num=2 en-affil=Division of Periodontology and Endodontology, Tohoku University Graduate School of Dentistry kn-affil= affil-num=3 en-affil=Division of Advanced Prosthetic Dentistry, Tohoku University Graduate School of Dentistry kn-affil= affil-num=4 en-affil=Division of Periodontology and Endodontology, Tohoku University Graduate School of Dentistry kn-affil= affil-num=5 en-affil=Division of Periodontology and Endodontology, Tohoku University Graduate School of Dentistry kn-affil= affil-num=6 en-affil=Division of Periodontology and Endodontology, Tohoku University Graduate School of Dentistry kn-affil= affil-num=7 en-affil=Department of Operative Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Division of Oral Microbiology and Immunology, Tohoku University Graduate School of Dentistry kn-affil= affil-num=9 en-affil=Division of Periodontology and Endodontology, Tohoku University Graduate School of Dentistry kn-affil= en-keyword=Cementocytes kn-keyword=Cementocytes en-keyword=Mechanotransduction kn-keyword=Mechanotransduction en-keyword=Piezo1 kn-keyword=Piezo1 en-keyword=Signal transduction kn-keyword=Signal transduction END start-ver=1.4 cd-journal=joma no-vol=2026 cd-vols= no-issue=2 article-no= start-page=023F01 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Feedback-Controlled Beam Pattern Measurement Method Using a Power-Variable Calibration Source for Cosmic Microwave Background Telescopes en-subtitle= kn-subtitle= en-abstract= kn-abstract=We demonstrate a novel beam pattern measurement method for the side lobe characterization of cosmic microwave background telescopes. 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 < 25 °C, adjusted ORs were 3.39 (25–27 °C), 8.81 (28–30 °C), and 22.10 (≥ 31 °C). Stratified analyses suggested stronger associations among several subgroups; however, only patients with mental disorders showed statistically significant effect modification, whereas elevated WBGT posed a risk across all groups.
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.

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=15 cd-vols= no-issue=5 article-no= start-page=372 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=Alpha-Ketoglutarate Drives an Osteogenic and Extracellular Matrix Gene Program in Periodontal Ligament Fibroblasts via Selective Reduction of H3K27me3 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Periodontal disease damages the tissues that support teeth and can ultimately lead to tooth loss, yet effective treatments to regenerate these tissues are still limited. Recent studies have shown that substances produced during normal cellular metabolism can influence how genes are regulated, but their role in periodontal regeneration has not been fully clarified. In this study, we investigated whether alpha-ketoglutarate, a naturally occurring metabolite involved in energy production, could promote periodontal tissue regeneration. We found that alpha-ketoglutarate enhanced bone-related and extracellular matrix-related gene expression in human periodontal ligament cells by reducing a repressive gene-regulatory signal that normally suppresses these genes. Importantly, alpha-ketoglutarate did not broadly alter chromatin accessibility, indicating that its effects were mediated through selective gene regulation. Furthermore, oral administration of alpha-ketoglutarate promoted alveolar bone regeneration and collagen-rich tissue formation in a mouse model of periodontal disease. Because alpha-ketoglutarate is a naturally occurring molecule in the body, these findings suggest that metabolite-based regulation of gene activity may represent a promising and safe approach for periodontal tissue regeneration. en-copyright= kn-copyright= en-aut-name=HasegawaRyu en-aut-sei=Hasegawa en-aut-mei=Ryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiShigeki en-aut-sei=Suzuki en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FahrezaRahmad Rifqi en-aut-sei=Fahreza en-aut-mei=Rahmad Rifqi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsaiShin-Ho en-aut-sei=Tsai en-aut-mei=Shin-Ho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DaidoujiYoshino en-aut-sei=Daidouji en-aut-mei=Yoshino kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OmoriMasato en-aut-sei=Omori en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KajikawaTetsuhiro en-aut-sei=Kajikawa en-aut-mei=Tetsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamadaSatoru en-aut-sei=Yamada en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Periodontology and Endodontology, Tohoku University Graduate School of Dentistry kn-affil= affil-num=2 en-affil=Department of Operative Dentistry, Okayama University Graduate School, Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Periodontology and Endodontology, Tohoku University Graduate School of Dentistry kn-affil= affil-num=4 en-affil=Department of Operative Dentistry, Okayama University Graduate School, Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Periodontology and Endodontology, Tohoku University Graduate School of Dentistry kn-affil= affil-num=6 en-affil=Department of Periodontology and Endodontology, Tohoku University Graduate School of Dentistry kn-affil= affil-num=7 en-affil=Department of Periodontology and Endodontology, Tohoku University Graduate School of Dentistry kn-affil= affil-num=8 en-affil=Department of Periodontology and Endodontology, Tohoku University Graduate School of Dentistry kn-affil= en-keyword=alpha-ketoglutarate kn-keyword=alpha-ketoglutarate en-keyword=periodontal ligament kn-keyword=periodontal ligament en-keyword=extracellular matrix kn-keyword=extracellular matrix en-keyword=epigenetic regulation kn-keyword=epigenetic regulation en-keyword=H3K27me3 kn-keyword=H3K27me3 END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=4 article-no= start-page=715 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260223 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Antigen Remodeling in Colorectal Cancer: How Radiotherapy and Chemotherapy Enhance Immunotherapy Responsiveness en-subtitle= kn-subtitle= en-abstract= kn-abstract=Colorectal cancer (CRC) is traditionally considered a “cold tumor” characterized by low immunogenicity and limited responsiveness to immune checkpoint inhibitors (ICIs). However, recent findings reveal that cytotoxic modalities can reprogram this immunologically inert landscape. This review integrates these evolving concepts to guide the optimization of future treatments. Radiotherapy induces extensive DNA double-strand breaks, which may generate de novo mutations through error-prone repair while simultaneously exposing cryptic antigens via increased transcriptional instability, alternative splicing, and enhanced proteasomal processing. Chemoradiation also amplifies epigenetic and epitranscriptomic sources of neoepitope diversity, including RNA editing and stress-induced splicing alterations, expanding the immunopeptidome beyond canonical mutation-driven neoantigens. These changes collectively enhance antigen presentation and facilitate T-cell priming. Chemotherapy further reduces immunosuppressive cell populations and promotes dendritic cell activation, creating a permissive milieu for subsequent immune engagement. Clinically, the VOLTAGE studies demonstrated that long-course chemoradiotherapy can sensitize even mismatch repair–proficient rectal cancers to PD-1 blockade, yielding clinically meaningful pathological responses. In contrast, mismatch repair–deficient rectal tumors may respond completely to ICIs alone. Short-course radiotherapy combined with chemotherapy and ICIs has also shown encouraging activity in the setting of total neoadjuvant therapy. Collectively, these findings support a paradigm in which radiotherapy, chemotherapy, and epigenetic/epitranscriptomic alterations—including RNA editing—act as potent modulators of tumor antigenicity. By expanding the neoantigen repertoire and reshaping the tumor microenvironment, these strategies can transform CRC from a cold tumor into one that is increasingly responsive to immunotherapy. en-copyright= kn-copyright= en-aut-name=MatsumiYuki en-aut-sei=Matsumi en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=TakahashiToshiaki en-aut-sei=Takahashi en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriwakeKazuya en-aut-sei=Moriwake en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KayanoMasashi en-aut-sei=Kayano en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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= en-keyword=colorectal cancer kn-keyword=colorectal cancer en-keyword=immunotherapy kn-keyword=immunotherapy en-keyword=radiotherapy kn-keyword=radiotherapy en-keyword=chemotherapy kn-keyword=chemotherapy en-keyword=neoantigens kn-keyword=neoantigens 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=20260221 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Turning pancreatic cancer from cold to hot: the promise of a p53-expressing oncolytic adenovirus (OBP-702) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pancreatic cancer remains one of the most lethal malignancies, with limited therapeutic options and poor responsiveness to immune checkpoint inhibitors (ICIs). This resistance is largely attributed to its profoundly immunosuppressive and desmoplastic tumor microenvironment (TME), characterized by low tumor mutational burden, dense stroma, and abundant immunosuppressive cell populations. Therefore, strategies capable of enhancing tumor immunogenicity and overcoming immune evasion are urgently needed. Oncolytic virotherapy is a promising approach, offering not only tumor-selective cytotoxicity, but also potent immunomodulatory effects. Of these agents, Telomelysin (OBP-301, Suratadenoturev), a telomerase-specific oncolytic adenovirus, demonstrated clinical safety but limited efficacy in refractory tumors. To address this challenge, we developed OBP-702, a next-generation, p53-armed, oncolytic adenovirus designed to augment antitumor activity. Preclinical studies have shown that OBP-702 exerts robust cytotoxicity through multiple mechanisms, including p53-mediated apoptosis and autophagy, E1A–E2F1-mediated p21 suppression, and inhibition of oncogenic KRAS pathways. Importantly, OBP-702 induces strong immunogenic cell death, activates dendritic cells, and promotes tumor-specific T-cell responses, effectively converting immunologically “cold” pancreatic tumors into “hot” tumors. OBP-702 also remodels the immunosuppressive TME by reducing granulocyte–macrophage colony-stimulating factor (GM-CSF) secretion, suppressing myeloid-derived suppressor cells (MDSCs), and targeting stromal components, such as cancer-associated fibroblasts (CAFs). These effects contribute to enhanced responses to ICIs and standard chemotherapies. Given its multifaceted antitumor functions and ability to overcome key barriers in pancreatic cancer, OBP-702 represents a highly promising therapeutic candidate. A first-in-human clinical trial evaluating endoscopic ultrasonography-guided intratumoral injection of OBP-702 is currently in preparation, expected to advance clinical translation of this novel virotherapeutic strategy. en-copyright= kn-copyright= en-aut-name=KurodaShinji en-aut-sei=Kuroda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TazawaHiroshi en-aut-sei=Tazawa en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HashimotoMasashi en-aut-sei=Hashimoto en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KanayaNobuhiko en-aut-sei=Kanaya en-aut-mei=Nobuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KakiuchiYoshihiko en-aut-sei=Kakiuchi en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=UrataYasuo en-aut-sei=Urata en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=Center for Innovative Clinical Medicine, Okayama University Hospital 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=Oncolys BioPharma Inc 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=Oncolytic adenovirus kn-keyword=Oncolytic adenovirus en-keyword=p53 kn-keyword=p53 en-keyword=OBP-702 kn-keyword=OBP-702 en-keyword=Immunogenic cell death kn-keyword=Immunogenic cell death en-keyword=Tumor microenvironment kn-keyword=Tumor microenvironment en-keyword=Pancreatic cancer kn-keyword=Pancreatic cancer END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=2 article-no= start-page=275 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260206 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Study on the Development of an Image Classification System for Urban Sprawl Areas in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=In Japan, unlike in many other countries, urbanization has progressed while original rural road structures have been retained, leading to distinctive urban sprawl areas with intermingling residential lots and farmland. Currently, much of Japan’s urban areas consist of urban sprawl areas, posing considerable challenges for infrastructure development. However, for such urban sprawl areas in Japan, it is difficult to say that methods have been established to identify their spatial distribution based on quantitative evaluation. Therefore, for this study, we used machine learning to investigate a system that extracts sprawling urban areas from aerial photographs divided into meshes. In the system’s design, we prioritized precision to ensure the reliable detection of urban sprawl areas. Consequently, the accuracy of identifying sprawl areas achieved precision of 0.81, recall of 0.63, and an F-score of 0.71. Examination of the classification results of sprawl areas revealed that most misclassifications occurred near class boundaries. By contrast, areas with particularly high levels of urban sprawl showed few misclassifications. en-copyright= kn-copyright= en-aut-name=HemmiRyota en-aut-sei=Hemmi en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UjiharaTakehito en-aut-sei=Ujihara en-aut-mei=Takehito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AndoRyosuke en-aut-sei=Ando en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HashimotoSeiji en-aut-sei=Hashimoto en-aut-mei=Seiji 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=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=National Institute for Land and Infrastructure Management, Ministry of Land, Infrastructure Transport and Tourism kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=image classification kn-keyword=image classification en-keyword=machine learning kn-keyword=machine learning en-keyword=sprawl kn-keyword=sprawl 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=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=

derivatives en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Purpose: Ascochlorin (ASC) is an antiviral antibiotic from the fermented broth of Ascochyta viciae which exerts an inhibitory effect to cancers. Its impact on immune cells has not been examined. In this study, we obtained ASC derivatives with less cytotoxicity and determined whether they affected T cells, indicating possible immune-mediated antitumour effects.
Experimental Approach: Newly synthesised ASC derivatives were screened for inhibitory effects on T-cell antigen receptor (TCR)-stimulated proliferative responses using murine CD4+ and CD8+ T cells. Two compounds were identified that exhibited >10-fold less toxicity compared with ASC. N184, the less toxic of the two, was analysed for its in vivo antitumour effects, and in vitro effects on CD8+ T-cell proliferation, survival, cytokine production and exhaustion, using microscopy, qPCR and flow cytometry.
Key Results: N184 induced limited IL-9 production in CD8+ T cells following TCR stimulation, thereby improving cell survival. It also enhanced cytokine production in the late phase of proliferation and suppressed the induction of exhaustion. N184 suppressed tumour growth in mice in a CD8+ T cell-dependent manner. The effect was partially prevented by an IL-9-neutralising antibody.
Conclusion and Implications: N184 induces differentiation of IL-9-producing CD8+ T cells in vitro and elicits antitumour immunity in an IL-9-dependent manner. en-copyright= kn-copyright= en-aut-name=ImanoNatsumi en-aut-sei=Imano en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishidaMikako en-aut-sei=Nishida en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TokumasuMiho en-aut-sei=Tokumasu en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZhaoWeiyang en-aut-sei=Zhao en-aut-mei=Weiyang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamashitaNahoko en-aut-sei=Yamashita en-aut-mei=Nahoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UdonoHeiichiro en-aut-sei=Udono en-aut-mei=Heiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Immunology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Metabolic Immune Regulation, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Immunology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Immunology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Metabolic Immune Regulation, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Metabolic Immune Regulation, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=ascochlorin derivative kn-keyword=ascochlorin derivative en-keyword=CD8 positive T lymphocytes kn-keyword=CD8 positive T lymphocytes en-keyword=cell survival kn-keyword=cell survival en-keyword=IFN-γ kn-keyword=IFN-γ en-keyword=interleukin-9 kn-keyword=interleukin-9 en-keyword=Tc9 kn-keyword=Tc9 en-keyword=tumour immunity kn-keyword=tumour immunity END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=4 article-no= start-page=1081 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260207 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Generative AI–Based Technical Data Extraction Tool for IoT Application Systems en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, Internet of Things (IoT) application systems play an essential role in smart cities, industry, healthcare, agriculture, and smart homes. For non-expert users, designing and implementing IoT application systems remains challenging, especially when configuring sensors, edge devices, and server platforms. To support configuration tasks of IoT application systems, we have developed an AI-based setup assistance tool. However, AI models still fail to reliably support newly released or previously unseen devices, sometimes producing incomplete or erroneous outputs that may lead to configuration failures. Incorporating their technical-document information into Retrieval-Augmented Generation (RAG) is an effective way to supplement AI knowledge and improve reliability. In this paper, we propose a generative AI-based technical data extraction tool to address the challenges. It extracts essential technical information using the schema-based extraction from given PDF or HTML datasheets and converts it into a structured format suitable for AI-supported configurations. A local vector database is used to enable semantic similarity retrieval and provide document-grounded evidence for RAG-based answering, ensuring consistent support for previously unseen IoT devices. For evaluations, we applied the proposal to several sensor and device datasheets and compared extracted specifications with ground-truth values to measure accuracy and completeness. Then, we compared end-to-end configuration QA reliability against a commercial baseline (ChatPDF) using the golden benchmark. The results show that the proposed tool reliably acquires key specifications and significantly improves end-to-end configuration QA reliability. Across 960 golden QA pairs, the proposed method improves Recall from 0.636 to 0.926 and Accuracy from 0.595 to 0.807 compared with ChatPDF. en-copyright= kn-copyright= en-aut-name=KongDezheng en-aut-sei=Kong en-aut-mei=Dezheng 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=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=ZhuZihao en-aut-sei=Zhu en-aut-mei=Zihao 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= 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= en-keyword=internet of things kn-keyword=internet of things en-keyword=AI kn-keyword=AI en-keyword=retrieval-augmented generation kn-keyword=retrieval-augmented generation en-keyword=vector database kn-keyword=vector database en-keyword=schema-based extraction kn-keyword=schema-based extraction en-keyword=data sheet kn-keyword=data sheet en-keyword=technical information kn-keyword=technical information END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=2 article-no= start-page=110 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=A Slide Annotation System with Multimodal Analysis 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 𝐹1 score of 0.879 (𝑆𝐷=0.024, 95% 𝐶𝐼[0.849,0.909]) for slide segmentation and 90.0% accuracy (95% 𝐶𝐼[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 (𝑆𝐷=6.7, 95% 𝐶𝐼[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=69 end-page=74 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=Effective Treatment of Advanced Hepatocellular Carcinoma with Extensive Peritoneal Dissemination Using Lenvatinib en-subtitle= kn-subtitle= en-abstract= kn-abstract=Patients with hepatocellular carcinoma (HCC) and extensive peritoneal dissemination generally have a poor prognosis and are often resistant to systemic therapy. We report the case of a 47-year-old woman with HCC and massive peritoneal dissemination who presented with malignant ascites requiring repeated cell-free and concentrated ascites reinfusion therapy and peritoneovenous shunt placement, as well as malignant pleural effusion requiring pleurodesis. Combined immunotherapy with durvalumab/tremelimumab was initiated;however, disease progression was observed after three treatment courses, prompting a switch to lenvatinib therapy. Two months after initiation of lenvatinib, CT imaging demonstrated complete disappearance of arterial enhancement in the primary hepatic lesion, along with reduction in the size of peritoneal dissemination nodules. Thirteen months after switching to lenvatinib (16 months after the initial diagnosis), the alpha-fetoprotein level continued to decrease, and the disease remained stable under treatment. Despite the extremely high tumor burden, lenvatinib achieved disease stabilization and symptomatic improvement. en-copyright= kn-copyright= en-aut-name=WakatsukiShinya en-aut-sei=Wakatsuki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakamotoShinya en-aut-sei=Sakamoto en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UenoAkiko en-aut-sei=Ueno en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NambaTakaomi en-aut-sei=Namba en-aut-mei=Takaomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoYorito en-aut-sei=Yamamoto en-aut-mei=Yorito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsumotoManabu en-aut-sei=Matsumoto en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IwataJun en-aut-sei=Iwata en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkabayashiTakehiro en-aut-sei=Okabayashi en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, Kochi Health Sciences Center kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Kochi Health Sciences Center kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Kochi Health Sciences Center kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Kochi Health Sciences Center kn-affil= affil-num=6 en-affil=Department of Diagnostic Pathology, Kochi Health Sciences Center kn-affil= affil-num=7 en-affil=Department of Diagnostic Pathology, Kochi Health Sciences Center kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= en-keyword=diagnostic laparoscopy kn-keyword=diagnostic laparoscopy en-keyword=hepatocellular carcinoma kn-keyword=hepatocellular carcinoma en-keyword=peritoneal dissemination kn-keyword=peritoneal dissemination en-keyword=lenvatinib kn-keyword=lenvatinib 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=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=9 end-page=16 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 Novel Nomogram that Predicts Chronic Hemodialysis Patients’ Survival Based on Their Sedentary Behavior en-subtitle= kn-subtitle= en-abstract= kn-abstract=Appropriate treatments for chronic hemodialysis patients are a public health challenge in Japan. Sedentary behavior appears to be closely associated with these patients’ survival. We thus sought to develop a nomogram that predicts survival based on the duration of chronic hemodialysis patients’ sedentary behavior. One hundred twenty-four patients under chronic hemodialysis (73 men, 51 women, age 71.7±11.1 years) were enrolled in this cohort study. The patients wore a triaxial accelerometer that measured both their sedentary behavior, i.e., total sedentary behavior (minutes) and their maximum sedentary bouts (min) on non-hemodialysis days. We obtained the Kaplan-Meier curve and used the log-rank test and a Cox proportional hazards model to evaluate the relationship between the patients’ sedentary behavior and their survival. We also used a Cox proportional hazards model to develop a nomogram for the patients’ 5-year survival rate. Forty-six patients died during the follow-up period. When we stratified the patients by the medians of total sedentary behavior and maximum sedentary bouts, we observed significant between-group differences. After adjustment for confounding factors in a Cox proportional hazards model, total sedentary behavior and maximum sedentary bouts were identified as critical survival factors, and we generated a nomogram using an index of sedentary behavior. Our analysis results demonstrated that sedentary behavior on non-dialysis days was closely associated with the survival of the chronic hemodialysis patients, suggesting that a decrease in sedentary behavior would prolong their survival. The nomogram developed herein based on sedentary behavior may be useful for predicting the outcomes of chronic hemodialysis patients. en-copyright= kn-copyright= en-aut-name=SugaharaKentaro en-aut-sei=Sugahara en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KondoTakashi en-aut-sei=Kondo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyatakeNobuyuki en-aut-sei=Miyatake en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishiHiroyuki en-aut-sei=Nishi en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UjikeKazuhiro en-aut-sei=Ujike en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KoumotoKiichi en-aut-sei=Koumoto en-aut-mei=Kiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NamioKeiichi en-aut-sei=Namio en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HishiiShuhei en-aut-sei=Hishii en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KatayamaAkihiko en-aut-sei=Katayama en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SuzukiHiromi en-aut-sei=Suzuki en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YamamotoYorimasa en-aut-sei=Yamamoto en-aut-mei=Yorimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=2 en-affil=Innoshima General Hospital kn-affil= affil-num=3 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=4 en-affil=Innoshima General Hospital kn-affil= affil-num=5 en-affil=Innoshima General Hospital kn-affil= affil-num=6 en-affil=Innoshima General Hospital kn-affil= affil-num=7 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=8 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=9 en-affil=Faculty of Social Studies, Shikokugakuin University kn-affil= affil-num=10 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=11 en-affil=Innoshima General Hospital kn-affil= en-keyword=nomogram kn-keyword=nomogram en-keyword=chronic hemodialysis kn-keyword=chronic hemodialysis en-keyword=sedentary behavior kn-keyword=sedentary behavior en-keyword=Cox proportional hazards model kn-keyword=Cox proportional hazards model en-keyword=Kaplan- Meier curve kn-keyword=Kaplan- Meier curve 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, appliqué, and brocade weaving. The subjects depicted encompass a wide range of themes within Tibetan Buddhism and the Bön 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=54 end-page=73 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 trajectory of rural field research and modernization discourse in American area studies: The Intersection of the University of Michigan’s Center for Japanese Studies Okayama Field Station, J.

This article examines the challenges of academic research under occupation and analyzes how such research was organized through specific actors and institutional arrangements, with particular attention to its intersection with the academic knowledge of the host institution, Okayama University. Focusing on the historian John W. Hall, it traces the activities of the Michigan field station and explores its interactions with Okayama University and the Seto Inland Sea Cultural Research Group. The article argues that while archival research—understood as a form of fieldwork—facilitated collaborative research, differing conceptions of rural society constituted a critical point of divergence in the production of scholarly knowledge. en-copyright= kn-copyright= en-aut-name=OSAShizue en-aut-sei=OSA en-aut-mei=Shizue kn-aut-name=長志珠絵 kn-aut-sei=長 kn-aut-mei=志珠絵 aut-affil-num=1 ORCID= affil-num=1 en-affil=Kobe University kn-affil= en-keyword=Michigan CJS Okayama Field Station kn-keyword=Michigan CJS Okayama Field Station en-keyword=John W.

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=33 cd-vols= no-issue=4 article-no= start-page=201045 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=Collagen depletion by pirfenidone enhances antitumor effect of oncolytic adenovirus against peritoneal metastases of gastric cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cancer-associated fibroblasts (CAFs) play a crucial role in collagen accumulation, which develops and promotes peritoneal metastasis (PM) in gastric cancer (GC). In addition, the abundant stromal collagens in the tumor microenvironment function as a physical barrier against penetration of antitumor drugs and oncolytic viruses. This study investigated whether collagen depletion by pirfenidone (PFD), an antifibrotic drug, enhances the antitumor effects of oncolytic adenoviruses. Analysis of the clinical samples revealed a significant association of high expression of collagen 1 and α-smooth muscle actin (α-SMA) with PM development and poor prognosis of advanced GC. Human and murine GC cells enhanced collagen production by fibroblasts, which was suppressed by PFD. Abundant fibroblasts and collagen inhibited the penetration of OBP-702, which reduced the antitumor effects of OBP-702 in the spheroid model. Intraperitoneal co-injection of GC cells and fibroblasts promoted the development of collagen-rich PM and reduced the antitumor effects of OBP-702 in vivo model. PFD suppressed collagen production in PM and improved viral penetration into the tumors, which enhanced the antitumor effects of OBP-702 against PM of GC. Collagen depletion by PFD enhances the penetration of OBP-702 into PM of GC, in turn enhancing the antitumor effects of OBP-702 against PM of GC. en-copyright= kn-copyright= en-aut-name=OkuraTomohiro

kn-title=The Influence of Fluidic Flow Stress on the Development of the Secondary Palate en-subtitle= kn-subtitle= en-abstract= kn-abstract=Craniofacial development is orchestrated by a finely regulated interplay of numerous genes and signaling pathways. Palatogenesis proceeds through a complex, stepwise process, in which endogenous mechanical stresses within tissues have been implicated. However, the impact of exogenous fluidic flow mechanical stress derived from maternal movement on palatal development remains unclear. In this study, we investigated the effect of exogenous fluidic flow mechanical stress on palatal morphogenesis, focusing on the horizontal outgrowth of palatal shelves after elevation. Palatal tissues dissected from mouse embryos were subjected to organ culture with or without mechanical loading (loaded and unloaded groups, respectively). Stress magnitude was quantified by calculating wave energy, and morphometric and molecular analyses were performed. Compared with the unloaded group, palatal shelves in the loaded group showed significant increases in thickness and volume, accompanied by enhanced cell proliferation, nuclear translocation of YAP and β-catenin, and upregulation of the osteogenic markers Osterix and Osteocalcin. No significant difference in apoptosis was observed. These findings indicate that exogenous mechanical stress promotes cell proliferation and osteogenic differentiation through the Hippo and WNT/β-catenin pathways in palate explants. Our results suggest that moderate maternal movement-induced mechanical stress contributes to normal palatogenesis, providing new insights into the mechanisms underlying cleft palate. en-copyright= kn-copyright= en-aut-name=NagataMasayo en-aut-sei=Nagata en-aut-mei=Masayo 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=WangZiyi en-aut-sei=Wang en-aut-mei=Ziyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KosamiTakahiro en-aut-sei=Kosami en-aut-mei=Takahiro 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= affil-num=1 en-affil=Department of Orthodontics, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Orthodontics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Molecular Biology and Biochemistry, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=mechanical stress kn-keyword=mechanical stress en-keyword=palatal development kn-keyword=palatal development en-keyword=β-catenin kn-keyword=β-catenin en-keyword=YAP kn-keyword=YAP 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 µm 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 µm) in AM specimens, along with step-like irregularities (~40 µm) 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=14 cd-vols= no-issue= article-no= start-page=RP106917 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260205 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dorsoventral-mediated Shh induction is required for axolotl limb regeneration en-subtitle= kn-subtitle= en-abstract= kn-abstract=Axolotls (Ambystoma mexicanum) exhibit a remarkable ability to regenerate limbs. Classical experiments have suggested that contact between cells derived from distinct orientations—dorsal, ventral, anterior, and posterior—within the regenerating blastema is necessary for accurate limb pattern formation. However, the molecular basis for this requirement has remained largely unknown. Here, we demonstrate that both dorsal and ventral tissues are required for limb formation via induction of Shh expression, which plays a crucial role in limb patterning. Using the accessory limb model, we induced position-specific blastemas lacking cells derived from a single orientation (anterior, posterior, dorsal, or ventral). Limb patterning occurred only in blastemas containing both dorsal- and ventral-derived cells. We further observed that Shh expression requires dorsoventral contact within a blastema, highlighting the necessity of dorsoventral contact for inducing Shh expression. Additionally, we identified WNT10B and FGF2 as dorsal- and ventral-mediated signals, respectively, that create the inductive environment for Shh expression. Our findings clarify the role of dorsal and ventral cells in inducing Shh, a mechanism that has rarely been studied in the context of limb regeneration and pattern formation. This model provides new insights into how cells with different positional identities drive the regeneration process. en-copyright= kn-copyright= en-aut-name=YamamotoSakiya en-aut-sei=Yamamoto en-aut-mei=Sakiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurukawaSaya en-aut-sei=Furukawa en-aut-mei=Saya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhashiAyaka en-aut-sei=Ohashi en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=SatohAkira en-aut-sei=Satoh en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= affil-num=2 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= affil-num=3 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= affil-num=4 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= affil-num=5 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=12 article-no= start-page=5742 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250615 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Specific Heat-Killed Lactic Acid Bacteria Enhance Mucosal Aminopeptidase N Activity in the Small Intestine of Aged Mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aminopeptidase N (APN), an enzyme expressed in the small intestinal mucosa, is involved in dietary protein digestion. Previous studies have shown that oral administration of fermented milk containing lactic acid bacteria (LAB) enhances mucosal APN activity in young mice. This study aimed to investigate whether LAB strains stimulate mucosal APN activity in aged mice and to evaluate its relevance to age-related changes in body composition. The underlying molecular mechanisms were also explored in vitro. Experiment 1: Aged C57BL/6J mice were fed diets supplemented with heat-killed LAB strains—Enterococcus faecalis OU-23 (EF), Leuconostoc mesenteroides OU-03 (LM), or Lactiplantibacillus plantarum SNK12 (LP). Compared to the aged Control group, the ileal APN activity was significantly higher in the LP group. LP administration also elevated serum Gla-osteocalcin levels and decreased serum CTX-1 levels. Experiment 2: IEC-6 cells were co-cultured with LP that had been treated with RNase, DNase, or lysozyme. APN activity was significantly lower in cells co-cultured with DNase- or lysozyme-treated LP compared to those co-cultured with untreated LP. A specific LAB strain may enhance mucosal APN activity in the aged intestine, potentially contributing to improved bone metabolism. This effect may be mediated by bacterial DNA and peptidoglycan. en-copyright= kn-copyright= en-aut-name=TsurutaTakeshi en-aut-sei=Tsuruta en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WakisakaMami en-aut-sei=Wakisaka en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeTakumi en-aut-sei=Watanabe en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishijimaAoi en-aut-sei=Nishijima en-aut-mei=Aoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IkedaAkihito en-aut-sei=Ikeda en-aut-mei=Akihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TeraokaMao en-aut-sei=Teraoka en-aut-mei=Mao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WangTianyang en-aut-sei=Wang en-aut-mei=Tianyang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ChenKuiyi en-aut-sei=Chen en-aut-mei=Kuiyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NishinoNaoki en-aut-sei=Nishino en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Bio-Lab Co., Ltd. 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= affil-num=6 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=aging kn-keyword=aging en-keyword=aminopeptidase N kn-keyword=aminopeptidase N en-keyword=bone metabolism kn-keyword=bone metabolism en-keyword=lactic acid bacteria kn-keyword=lactic acid bacteria en-keyword=small intestine kn-keyword=small intestine END start-ver=1.4 cd-journal=joma no-vol=123 cd-vols= no-issue=6 article-no= start-page=e2518136123 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260204 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A nuclear CobW/WW-domain factor represses the CO2-concentrating mechanism in the green alga Chlamydomonas reinhardtii en-subtitle= kn-subtitle= en-abstract= kn-abstract=Microalgae induce a CO2-concentrating mechanism (CCM) to maintain photosynthesis when CO2 is limited. Because this system consumes a substantial portion of photosynthetically generated ATP, its suppression when CO2 levels rise is critical for energy balance, yet the underlying mechanism remains unclear. Here, we identify a nuclear repressor of the CCM in the green alga Chlamydomonas reinhardtii. A pull-down screen for interacting partners of the master activator CCM1/CIA5 revealed an uncharacterized protein that tightly associates with CCM1. This protein, CCM1-binding protein 1 (CBP1), combines a CobW/CobW_C GTP-binding metallochaperone module with a WW-domain characteristic of protein–protein interactions. CBP1 colocalizes and interacts with CCM1 in the nucleus regardless of CO2 conditions. Disruption of CBP1 does not affect growth or CCM induction under CO2 limitation but derepresses 27 of 41 CCM1-dependent low-CO2 inducible genes under high-CO2 conditions. These include the periplasmic and intracellular carbonic anhydrases (CAH1 and LCIB) and inorganic carbon transporters/channels (LCIA, LCI1, BST1, and BST3). Consistently, cbp1 mutants accumulate CAH1 and LCIB proteins and exhibit 40% higher inorganic carbon affinity under high-CO2 conditions; this phenotype is rescued by CBP1 complementation or by acetazolamide treatment. Crucially, cbp1 mutants exhibit significant growth delays under high-CO2 conditions, especially when light is limiting, providing direct evidence that CBP1-mediated repression is essential for energy conservation. Thus, CBP1 prevents unnecessary CCM activity when CO2 is abundant, acting upstream of both transporter/channel and carbonic anhydrase modules. Our findings suggest a regulatory mechanism potentially linking zinc-dependent protein chemistry to CCM gene repression, providing insights into energy-efficient CO2 sensing in aquatic photosynthetic organisms. en-copyright= kn-copyright= en-aut-name=ShimamuraDaisuke en-aut-sei=Shimamura en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YasudaJunko en-aut-sei=Yasuda en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamaharaYosuke en-aut-sei=Yamahara en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakanoHirobumi en-aut-sei=Nakano en-aut-mei=Hirobumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OzawaShin-Ichiro en-aut-sei=Ozawa en-aut-mei=Shin-Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TokutsuRyutaro en-aut-sei=Tokutsu en-aut-mei=Ryutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamagamiAyumi en-aut-sei=Yamagami en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsushitaTomonao en-aut-sei=Matsushita en-aut-mei=Tomonao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakahashiYuichiro en-aut-sei=Takahashi en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakanoTakeshi en-aut-sei=Nakano en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FukuzawaHideya en-aut-sei=Fukuzawa en-aut-mei=Hideya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YamanoTakashi en-aut-sei=Yamano en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Graduate School of Biostudies, Division of Integrated Life Science, Kyoto University kn-affil= affil-num=2 en-affil=Graduate School of Biostudies, Division of Integrated Life Science, Kyoto University kn-affil= affil-num=3 en-affil=Graduate School of Biostudies, Division of Integrated Life Science, Kyoto University kn-affil= affil-num=4 en-affil=Graduate School of Biostudies, Division of Integrated Life Science, Kyoto University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Science, Division of Biological Sciences, Kyoto University kn-affil= affil-num=7 en-affil=Graduate School of Biostudies, Division of Integrated Life Science, Kyoto University kn-affil= affil-num=8 en-affil=Graduate School of Science, Division of Biological Sciences, Kyoto University kn-affil= affil-num=9 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=10 en-affil=Graduate School of Biostudies, Division of Integrated Life Science, Kyoto University kn-affil= affil-num=11 en-affil=Graduate School of Biostudies, Division of Integrated Life Science, Kyoto University kn-affil= affil-num=12 en-affil=Graduate School of Biostudies, Division of Integrated Life Science, Kyoto University kn-affil= en-keyword=carbonic anhydrase kn-keyword=carbonic anhydrase en-keyword=Chlamydomonas reinhardtii kn-keyword=Chlamydomonas reinhardtii en-keyword=CO2-concentrating mechanism kn-keyword=CO2-concentrating mechanism en-keyword=photosynthesis kn-keyword=photosynthesis en-keyword=pyrenoid kn-keyword=pyrenoid 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.

Although surgical resection remains the standard treatment, its invasiveness has prompted interest in less invasive alternatives, particularly for small non-functional pNETs (NF-pNETs) and insulinomas.
Objectives: To evaluate the clinical efficacy and safety of endoscopic ultrasound-guided ethanol injection (EUS-EI) and radiofrequency ablation (EUS-RFA) for pNETs.
Design: A systematic review and meta-analysis.
Data sources and methods: A literature search of PubMed, MEDLINE, and Google Scholar was conducted (April 2005–April 2025). Studies were eligible if they reported clinical outcomes of EUS-EI or EUS-RFA in adult patients with insulinomas or NF-pNETs. The primary endpoints were clinical success (short-term symptom resolution or radiological response) and adverse event (AE) rates. Data were pooled using a random-effects model.
Results: Twenty-six studies were included in the meta-analysis. For insulinomas, the pooled clinical success rate was 77% (95% confidence interval (CI), 59–88) for EUS-EI and 95% (95% CI, 89–97) for EUS-RFA. The pooled incidence of total AEs was 32% (95% CI, 17–51) for EUS-EI and 25% (95% CI, 15–39) for EUS-RFA. For NF-pNETs, the pooled clinical success rates were 76% (95% CI, 54–90) for EUS-EI and 85% (95% CI, 74–92) for EUS-RFA, and the pooled incidence of total AEs was 27% (95% CI, 20–35) and 26% (95% CI, 17–38), respectively. The most common moderate or severe AEs were pancreatitis in 12 patients (7.6%) after EUS-EI, and pancreatic fluid collection in 4 patients (1.9%) and pancreatic duct stricture in 3 patients (1.4%) after EUS-RFA. One fatal case occurred in a 97-year-old patient following EUS-RFA.
Conclusion: Both EUS-EI and EUS-RFA are effective, relatively safe, and minimally invasive treatment options for pNETs. However, severe AE can occur, and careful patient selection and treatment indication are essential.

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=18 cd-vols= no-issue=1 article-no= start-page=e102426 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Central Serous Chorioretinopathy in Parallel With Onset and Relapses of Minimal Change Nephrotic Syndrome: A 28-Year Case Follow-Up en-subtitle= kn-subtitle= en-abstract= kn-abstract=Central serous chorioretinopathy is an idiopathic disease that manifests as one or several localized, small, dome-shaped serous retinal detachments on fundus examination. 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=16 cd-vols= no-issue=3 article-no= start-page=369 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260123 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of the July 2018 Heavy Rain Disaster on the Endangered Nagoya Daruma Pond Frog (Pelophylax porosus brevipodus) in Rice Fields of Mabi Town, Kurashiki City, Western Japan: Changes in Population Structure over Five Years en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rice paddy fields (referred to below as rice fields) are important not only for food production, but also as habitats for various species. The Nagoya Daruma Pond Frog (Pelophylax porosus brevipodus) is an endangered frog species endemic to Japan, mainly living in and around rice field areas. In July 2018, heavy rainfall caused severe flooding in Mabi Town of Okayama Prefecture, western Japan, submerging numerous rice fields and affecting local frog populations, including P. porosus brevipodus. To clarify whether the population structure of P. porosus brevipodus changed following the flood disaster in the rice fields of Mabi Town, we conducted quantitative field surveys in a rice fallow field in mid-October before (2017) and after (2018, 2020–2022, excluding 2019) the flood. The number of frogs declined sharply after the 2018 flood, reaching only a few individuals by 2020, but showed a substantial recovery in 2021 following the resumption of rice cultivation, although numbers decreased again in 2022. This recovery, despite fluctuations, indicates that habitat restoration through rice farming played a key role in enabling the population to rebound. Our findings underscore the importance of maintaining and restoring rice field environments after natural disasters for the survival and long-term recovery of P. porosus brevipodus. en-copyright= kn-copyright= en-aut-name=NakajimaRyo en-aut-sei=Nakajima en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AzumiDaisuke en-aut-sei=Azumi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TadaMasakazu en-aut-sei=Tada en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakaichiJunya en-aut-sei=Nakaichi en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatsuharaKoki R. en-aut-sei=Katsuhara en-aut-mei=Koki R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakataKazuyoshi en-aut-sei=Nakata en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=Okayama Prefectural Public Interest Incorporated Foundation for Environmental Conservation 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= en-keyword=agroecosystem kn-keyword=agroecosystem en-keyword=conservation ecology kn-keyword=conservation ecology en-keyword=endangered amphibian kn-keyword=endangered amphibian en-keyword=paddy field kn-keyword=paddy field en-keyword=post-disaster habitat recovery kn-keyword=post-disaster habitat recovery 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=20260120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=SPRED2 suppresses the stemness of hepatocellular carcinoma through the p53/miR-506-3p/KLF4 pathway en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: We previously reported that endogenous Sprouty-related, EVH1 domain-containing protein 2 (SPRED2), an inhibitor of the Ras/Raf/ERK-MAPK pathway, controls hepatocellular carcinoma (HCC) cell stemness by downregulating the expression of pluripotency factors, such as Nanog, c-Myc, and KLF4, in an ERK-dependent fashion. However, the exact mechanisms by which SPRED2 regulates HCC cell stemness have not been established.
Methods: Three human HCC cell lines [HepG2 (parental and SPRED2-deficient), HLE, and Hep3B] were used. Cells were transfected to downregulate or overexpress proteins. Western blot and RT-qPCR were used to evaluate the level of protein and mRNA expression. Co-immunoprecipitation and ChIP-qPCR were used to examine protein-protein interactions and the activation of gene transcription. Clinical HCC tissues were also used to validate in vitro data.
Results: KLF4 was identified as the major pluripotency factor responsible for SPRED2-mediated downregulation of HCC cell stemness and KLF4 expression was regulated by miR-506-3p. SPRED2 formed a protein complex with the tumor suppressor (p53) and upregulated miR-506 gene transcription by binding to the promoter region, resulting in subsequent downregulation of KLF4 mRNA expression. There was a negative correlation between KLF4 expression and miR-506-3p and a positive correlation between miR-506-3p expression and SPRED2 in human HCC samples, highlighting the relevance of the study findings.
Conclusions: The current study revealed a novel SPRED2/p53/miR-506-3p/KLF4 axis through which SPRED2 contributes to the suppression of HCC cell stemness and provides a potential new target to prevent HCC progression. en-copyright= kn-copyright= en-aut-name=GaoTong en-aut-sei=Gao en-aut-mei=Tong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ItoSachio en-aut-sei=Ito en-aut-mei=Sachio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Moh-Moh-AungAye en-aut-sei=Moh-Moh-Aung en-aut-mei=Aye kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangTianyi en-aut-sei=Wang en-aut-mei=Tianyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujisawaMasayoshi en-aut-sei=Fujisawa en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshimuraTeizo en-aut-sei=Yoshimura en-aut-mei=Teizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathophysiology and Drug Discovery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=SPRED2 kn-keyword=SPRED2 en-keyword=p53 kn-keyword=p53 en-keyword=KLF4 kn-keyword=KLF4 en-keyword=miR-506-3p kn-keyword=miR-506-3p en-keyword=stemness kn-keyword=stemness END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=1 article-no= start-page=10 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260121 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bridging the Gap Between Static Histology and Dynamic Organ-on-a-Chip Models en-subtitle= kn-subtitle= en-abstract= kn-abstract=For more than a century, pathology has served as a cornerstone of modern medicine, relying primarily on static microscopic assessment of tissue morphology—such as H&E staining—which remains the “gold standard” for disease diagnosis. However, this conventional paradigm provides only a snapshot of disease states and often fails to capture their dynamic evolution and complex functional mechanisms. Moreover, animal models are constrained by marked interspecies differences, creating a persistent gap in translational research. To overcome these limitations, we propose the concept of New Pathophysiology, a research framework that transcends purely morphological descriptions and aims to resolve functional dynamics in real time. This approach integrates Organ-on-a-Chip (OOC) technology, multi-omics analyses, and artificial intelligence to reconstruct the entire course of disease initiation and to enable personalized medicine. In this review, we first outline the foundations and limitations of traditional pathology and animal models. We then systematically summarize more than one hundred existing OOC disease models across multiple organs—including the kidney, liver, and brain. Finally, we elaborate on how OOC technologies are reshaping the study of key pathological processes such as inflammation, metabolic dysregulation, and fibrosis by converting them into dynamic, mechanistic disease models, and we propose future perspectives in the field. This review adopts a relatively uncommon classification strategy based on pathological mechanisms (mechanism-based), rather than organ-based categorization, allowing readers to recognize shared principles underlying different diseases. Moreover, the focus of this work is not on emphasizing iteration or replacement of existing approaches, but on preserving past achievements from a historical perspective, with an emphasis on overcoming current limitations and enabling new advances. en-copyright= kn-copyright= en-aut-name=WangZheyi en-aut-sei=Wang en-aut-mei=Zheyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=TakahashiKen en-aut-sei=Takahashi en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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 Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=new pathophysiology kn-keyword=new pathophysiology en-keyword=organ-on-a-chip/OOC kn-keyword=organ-on-a-chip/OOC en-keyword=dynamic disease modeling kn-keyword=dynamic disease modeling en-keyword=histopathology kn-keyword=histopathology en-keyword=large-model analysis kn-keyword=large-model analysis en-keyword=personalized medicine kn-keyword=personalized medicine 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.

Material and Methods: This retrospective, single-institution study included 391 computed tomography-guided lung biopsies performed by 12 operators between January 2022 and October 2024. After exclusion, 298 biopsies were analyzed by comparing the saline seal (n = 138) and control (n = 160) groups. A 17/18-gauge or 19/20-gauge coaxial biopsy system was used, and tract sealing was performed by instilling 1-5 mL of normal saline during the withdrawal of the introducer needle in the saline seal group; tract sealing was not performed in the control group. After 1:1 propensity score matching was performed to balance baseline characteristics, the incidences of pneumothorax and chest tube placement were compared between the two groups using Fisher's exact test.
Results: After propensity score matching, 108 pairs (mean lesion size: 17 mm) were well balanced. The incidence of pneumothorax did not differ significantly between the control and saline seal groups (50.0% vs. 60.2%, respectively; p = 0.171). Similarly, the incidence of chest tube placement was not significantly different between the two groups (7.4% vs. 13.0%, respectively; p = 0.260).
Conclusions: According to the propensity score-matched analysis, normal saline instillation for tract sealing did not significantly reduce the incidence of pneumothorax or chest tube placement. In our cohort, which had a high prevalence of small lesions, saline sealing alone may be insufficient to reduce post-biopsy pneumothorax risk. Hence, combined strategies require further investigation. en-copyright= kn-copyright= en-aut-name=OkamotoSoichiro en-aut-sei=Okamoto en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TomitaKoji en-aut-sei=Tomita en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MunetomoKazuaki en-aut-sei=Munetomo en-aut-mei=Kazuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UmakoshiNoriyuki en-aut-sei=Umakoshi en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Center for Innovative Clinical Medicine, Medical Development Field, Okayama University kn-affil= affil-num=7 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=pneumothorax kn-keyword=pneumothorax en-keyword=lung biopsy kn-keyword=lung biopsy en-keyword=image-guided biopsy kn-keyword=image-guided biopsy en-keyword=needle tract sealing kn-keyword=needle tract sealing END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue=1 article-no= start-page=116781 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=Immunopeptidomics combined with full-length transcriptomics uncovers diverse neoantigens en-subtitle= kn-subtitle= en-abstract= kn-abstract=Neoantigens are crucial for antitumor immunity and immune checkpoint inhibitor (ICI) efficacy by triggering strong immune responses. However, conventional methods for identifying neoantigens, such as whole-exon sequencing and short-read RNA sequencing (RNA-seq), appear to be insufficient, and the tumor mutational burden cannot sufficiently predict ICI efficacy. In this study, we employed a proteogenomic approach using long-read RNA-seq with Pacific Biosciences Single-Molecule Real-Time Sequencing technology to analyze full-length transcripts in combination with the human leukocyte antigen ligandome. As a result, many neoantigen candidates were identified, which were unregistered in a comprehensive database, including those from non-coding regions. Additionally, we validated the responses of specific T cell receptors (TCRs) to these candidates and identified several pairs of TCRs and neoantigens. These findings highlight the presence of more diverse neoantigens than expected that cannot be identified by conventional methods. en-copyright= kn-copyright= en-aut-name=IshinoTakamasa

en-subtitle= kn-subtitle= en-abstract= kn-abstract=Deep-origin carbonatite melts are considered to be the products of partial-melting of the oceanic crust in the subduction zones. 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= 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=KunioshiNílson en-aut-sei=Kunioshi en-aut-mei=Nílson 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=29 cd-vols= no-issue= article-no= start-page=108948 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=Unified 2D polygon-based CAM framework integrating tool path generation, machinability evaluation, and cutting-force simulation en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study proposes a unified two-dimensional (2D) polygon-based computer-aided manufacturing (CAM) framework that enables tool path generation, machinability evaluation, material removal simulation, and cutting-force prediction within a single computational environment. The proposed method represents three-dimensional geometries as aggregates of orthogonal 2D polygon sets, obtained by slicing the model in the xy-, yz-, and zx-parallel planes and superposing the three polygonal datasets. A novel convolutional offsetting algorithm is developed to perform three-dimensional inflation and shrinkage by incorporating adjacent cross-sectional relationships, thereby achieving accurate 3D offsets independent of the slicing orientation. The inflated 2D polygons are directly utilized to generate contour and scanning tool paths, and sequential inflation–shrinkage analysis enables visualization of unmachinable regions for tool accessibility evaluation. Furthermore, the framework integrates an instantaneous cutting force model that accurately predicts the cutting force waveform by detecting intersections between the cutting edge points and 2D polygon aggregations. The system is experimentally validated via ball-end milling. The results demonstrate that tool paths can be generated in under one minute using only a CPU. Furthermore, the simulated cutting forces closely align with experimental measurements. These findings demonstrate that the proposed 2D polygon-based framework provides an efficient and extensible foundation for integrating mechanical simulation and tool-path generation. en-copyright= kn-copyright= en-aut-name=KanekoKazuki en-aut-sei=Kaneko en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakayasuHiroto en-aut-sei=Takayasu en-aut-mei=Hiroto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SuzukiAtsuya en-aut-sei=Suzuki en-aut-mei=Atsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KodamaHiroyuki en-aut-sei=Kodama en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Science and Engineering, Ibaraki University kn-affil= affil-num=3 en-affil=Mechanical Systems Engineering Program, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Computer-aided manufacturing (CAM) kn-keyword=Computer-aided manufacturing (CAM) en-keyword=Polygon kn-keyword=Polygon en-keyword=Tool path generation kn-keyword=Tool path generation en-keyword=Machinability kn-keyword=Machinability en-keyword=Cutting force prediction kn-keyword=Cutting force prediction 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

opening moments of the video game The Last of Us Part I, players are introduced to an emerging pandemic via Austin’s Texas Herald newspaper. Below a headline warning of mass hospitalizations from a 'mysterious infection', players read of a recall of imported crops 'potentially tainted with mold': 'Initial lists distributed to vendors nationwide warned against crops imported from South America. However now the scope has extended to include Central America and Mexico'. This scene immediately suggests the racialization of the franchise’s Cordyceps brain infection (CBI), with the contagion germinating in the global South, invading the US via its southern border, and spreading fastest in the nation’s diverse urban centres. By highlighting tainted crops as the vector of dispersal in the US, however, rather than infected humans, the franchise resists making this a simple invasion-scare narrative and instead suggests that the spread of the infection is in part a result of the capitalist exploitation of cheap land and labour in the global South. Despite its inconsistent record on racial representation and the near-absence of discussion of race across the franchise, the structures reflecting the racialization of contagion and the perpetuation of racialized hierarchies through defensive biopolitics remain present. Drawing connections with the discourse around immigration and the southern border and contemporary pandemics and epidemics, this article makes the case for reading the franchise in terms of racialized contagion and defensive biopolitics, a reading that highlights how the games and their television adaptation reflect urgent contemporary issues around race in America. en-copyright= kn-copyright= en-aut-name=YeatesRobert en-aut-sei=Yeates en-aut-mei=Robert kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Faculty of Humanities and Social Sciences, Okayama University kn-affil= en-keyword=the last of us kn-keyword=the last of us en-keyword=contagion kn-keyword=contagion en-keyword=pandemics kn-keyword=pandemics en-keyword=race kn-keyword=race en-keyword=immigration kn-keyword=immigration en-keyword=biopolitics kn-keyword=biopolitics END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=47 article-no= start-page=5035 end-page=5039 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=Synthesis of sterically unhindered Lewis acidic boron-doped π-conjugated polymers en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report the synthesis of sterically unhindered boron-doped π-conjugated polymers via polymerization of organo-dilithium reagents with boron trichloride.

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=BlömerSophia en-aut-sei=Blömer en-aut-mei=Sophia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Şahin KayaAysel en-aut-sei=Şahin Kaya en-aut-mei=Aysel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KrügerSandra en-aut-sei=Krüger en-aut-mei=Sandra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=RöckenChristoph en-aut-sei=Röcken en-aut-mei=Christoph kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SchäferHeiner en-aut-sei=Schäfer 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=16 cd-vols= no-issue= article-no= start-page=1713471 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=Regulatory considerations for developing phage therapy medicinal products for the treatment of antimicrobial resistant bacterial infections en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recently, there have been growing expectations that treatment of infections with bacteriophages (phages), viruses which specifically infect bacteria, can be used as a treatment option for antimicrobial resistant bacterial infections. In Europe and the United States, in addition to phage therapy as a form of personalized medicine, development of pre-defined phage therapy medicinal products (PTMPs) is progressing, and clinical trials are underway. From October 2024 to July 2025, the Pharmaceuticals and Medical Devices Agency exchanged opinions on trends and points to consider in drug development of PTMPs used for antimicrobial resistant bacterial infections with external experts. Development of PTMPs for regulatory approval requires quality control strategies, establishment of manufacturing methods, non-clinical evaluations, and clinical trial plans based on the characteristics of the phage. In this document, based on the regulatory and development trends in Europe and the United States, the current considerations on quality, non-clinical evaluation, and clinical trial planning including the Cartagena Act in the development of PTMPs in Japan are summarized. The basic concepts presented here are intended to be applied to antimicrobial resistant bacterial infections targeted by PTMPs but can be mostly applicable to bacterial infections in general. We hope that these findings will further accelerate more active development of PTMPs towards timely patient access to innovative products. en-copyright= kn-copyright= en-aut-name=Fukaya-ShibaAi

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=PiñaJeremie Oliver en-aut-sei=Piña 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=35 cd-vols= no-issue=2 article-no= start-page=101548 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cerebellar abscess caused by Cladophialophora bantiana involving an elderly Japanese woman en-subtitle= kn-subtitle= en-abstract= kn-abstract=Phaeohyphomycosis is a rare fungal infection that presents significant challenges in diagnosis and treatment. Herein, we document a case of a cerebellar abscess caused by Cladophialophora bantiana. A 77-year-old woman with type 2 diabetes mellitus and a previous history of diffuse large B-cell lymphoma gradually developed ataxia and was transferred to an emergency department. Head imaging investigations indicated a cerebellar mass and the patient underwent an emergent endoscopic drainage. Although bacterial cultures of the drainage specimen yielded no growth, a dematiaceous fungus was isolated and subsequently identified as C. bantiana through ITS sequencing analysis. The patient received antifungal combination therapy, initially with liposomal amphotericin B and voriconazole, and finally posaconazole and 5-fluorocytosine. Brain abscesses caused by C. bantiana are rarely documented, and an optimal treatment strategy has yet to be established. Given the high fatality rate, an early surgical intervention is crucial for both diagnosis and treatment. The present case was successfully treated with minimally invasive surgical intervention alongside the antifungal combination therapy. en-copyright= kn-copyright= en-aut-name=NakamotoKenta en-aut-sei=Nakamoto en-aut-mei=Kenta 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=OguniKohei en-aut-sei=Oguni en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YokoyamaYukika en-aut-sei=Yokoyama en-aut-mei=Yukika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=HiranoShuichiro en-aut-sei=Hirano en-aut-mei=Shuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YaguchiTakashi en-aut-sei=Yaguchi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=BanSayaka en-aut-sei=Ban en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=WatanabeAkira en-aut-sei=Watanabe en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OkunobuHiroki en-aut-sei=Okunobu en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= en-aut-name=KawaguchiMarina en-aut-sei=Kawaguchi en-aut-mei=Marina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=SazumiYousuke en-aut-sei=Sazumi en-aut-mei=Yousuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 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=15 ORCID= affil-num=1 en-affil=Department of Infectious Diseases, 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=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=6 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital 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=Division of Clinical Research, Medical Mycology Research Center kn-affil= affil-num=9 en-affil=Division of Clinical Research, Medical Mycology Research Center kn-affil= affil-num=10 en-affil=Division of Clinical Research, Medical Mycology Research Center kn-affil= affil-num=11 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=15 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Brain abscess kn-keyword=Brain abscess en-keyword=Cladophialophora bantiana kn-keyword=Cladophialophora bantiana en-keyword=Black fungus kn-keyword=Black fungus en-keyword=Phaeohyphomycosis kn-keyword=Phaeohyphomycosis en-keyword=Posaconazole kn-keyword=Posaconazole END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=16 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251229 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=FluoNeRF: Fluorescent Novel-View Synthesis Under Novel Light Source Colors and Spectra en-subtitle= kn-subtitle= en-abstract= kn-abstract=Synthesizing photo-realistic images of a scene from arbitrary viewpoints and under arbitrary lighting environments is one of the important research topics in computer vision and graphics. In this paper, we propose a method for synthesizing photo-realistic images of a scene with fluorescent objects from novel viewpoints and under novel lighting colors and spectra. In general, fluorescent materials absorb light with certain wavelengths and then emit light with longer wavelengths than the absorbed ones, in contrast to reflective materials, which preserve wavelengths of light. Therefore, we cannot reproduce the colors of fluorescent objects under arbitrary lighting colors by combining conventional view synthesis techniques with the white balance adjustment of the RGB channels. Accordingly, we extend the novel-view synthesis based on the neural radiance fields by incorporating the superposition principle of light; our proposed method captures a sparse set of images of a scene from varying viewpoints and under varying lighting colors or spectra with active lighting systems such as a color display or a multi-spectral light stage and then synthesizes photo-realistic images of the scene without explicitly modeling its geometric and photometric models. We conducted a number of experiments using real images captured with an LCD and confirmed that our method works better than the existing methods. Moreover, we showed that the extension of our method using more than three primary colors with a light stage enables us to reproduce the colors of fluorescent objects under common light sources. en-copyright= kn-copyright= en-aut-name=ShiLin en-aut-sei=Shi en-aut-mei=Lin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsufujiKengo en-aut-sei=Matsufuji en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=KawaharaRyo en-aut-sei=Kawahara en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkabeTakahiro en-aut-sei=Okabe en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Artificial Intelligence, Kyushu Institute of Technology kn-affil= affil-num=2 en-affil=Department of Artificial Intelligence, Kyushu Institute of Technology kn-affil= affil-num=3 en-affil=Department of Computer Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Informatics, Kyoto University kn-affil= affil-num=5 en-affil=Department of Computer Science, Okayama University kn-affil= en-keyword=novel-view synthesis kn-keyword=novel-view synthesis en-keyword=neural radiance fields kn-keyword=neural radiance fields en-keyword=relighting kn-keyword=relighting en-keyword=superposition principle kn-keyword=superposition principle en-keyword=fluorescence kn-keyword=fluorescence en-keyword=Stokes shift kn-keyword=Stokes shift END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=11 article-no= start-page=e97931 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=Perioperative Multidisciplinary Intervention Led to Complete Minimally Invasive Transthoracic Esophagectomy for a Patient With Severe Lung Dysfunction: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Risk factors for postoperative pneumonia after esophagectomy include smoking, severe lung dysfunction, and sarcopenia. Heavy smokers often have chronic obstructive pulmonary disease (COPD), which is associated with poor physical activity and low muscle strength. Sarcopenia is also associated with decreased physical function and malnutrition. These factors lead to a close relationship between COPD and sarcopenia. This report describes the case of a 74-year-old man who presented with dysphagia and was diagnosed with advanced esophageal cancer with lymph node metastasis. Preoperative respiratory function testing showed a forced expiratory volume in one second (FEV1) of 0.76 L because of his past smoking and COPD. Multidisciplinary intervention was started, along with neoadjuvant chemotherapy. Preoperative management improved his physical function. Robot-assisted thoracoscopic subtotal esophagectomy with the patient in the prone position was performed with curative resection and no severe postoperative complications. The perioperative multidisciplinary intervention improved physical functions and enabled safe robot-assisted thoracoscopic esophagectomy for the patient with severe lung dysfunction in the prone position. This case highlights that not only respiratory status but also physical parameters should be taken into account when considering whether a patient can tolerate surgery safely. en-copyright= kn-copyright= en-aut-name=MatsumotoMakoto en-aut-sei=Matsumoto en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HashimotoMasashi en-aut-sei=Hashimoto en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawasakiKento en-aut-sei=Kawasaki en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KunitomoTomoyoshi en-aut-sei=Kunitomo en-aut-mei=Tomoyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaedaNaoaki en-aut-sei=Maeda en-aut-mei=Naoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanabeShunsuke en-aut-sei=Tanabe en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro 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=copd kn-keyword=copd en-keyword=esophagectomy kn-keyword=esophagectomy en-keyword=perioperative multidisciplinary intervention kn-keyword=perioperative multidisciplinary intervention en-keyword=perioperative rehabilitation kn-keyword=perioperative rehabilitation en-keyword=respiratory function training and rehabilitation kn-keyword=respiratory function training and rehabilitation en-keyword=sarcopenia kn-keyword=sarcopenia en-keyword=severe pulmonary dysfunction kn-keyword=severe pulmonary dysfunction 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-di­meth­oxy­thio­phen-2-yl)phen­yl]amine (DMOT-TPA), C36H33NO6S3, the central nitro­gen atom shows no pyramidalization, with the three para-phenyl­ene rings arranged in a propeller-like geometry. Each thio­phene ring is twisted by about 25–29° relative to the adjacent phenyl­ene ring, giving a distorted π-conjugated framework. In the crystal, mol­ecules are linked through multiple C—H⋯π inter­actions into two-dimensional sheets, which extend into a three-dimensional network. A Cambridge Structural Database survey revealed no prior examples of tri­phenyl­amines bearing 3,4-di­meth­oxy­thio­phen units at the para positions.

Here, we report a 2.82-angstrom cryo–electron microscopy structure of the PSI-LHCI supercomplex from Euglena gracilis, a eukaryotic alga with secondary green alga-derived plastids. The structure reveals a PSI monomer core with eight subunits and 13 asymmetrically arranged LHCI proteins. Euglena LHCIs bind diadinoxanthin, which is one of the carotenoids typically associated with red-lineage LHCs and is not present in the canonical LHCI belt found in green-lineage PSI-LHCI structures. Phylogenetic analysis shows that the Euglena LHCIs originated from LHCII-related clades rather than from the green-lineage LHCI group and that the nuclear-encoded PSI subunit PsaD likely originated from cyanobacteria via horizontal gene transfer. These observations indicate a mosaic origin of the Euglena PSI-LHCI. Our findings uncover a noncanonical light-harvesting architecture and highlight the structural and evolutionary plasticity of photosynthetic systems, illustrating how endosymbiotic acquisition and lineage-specific adaptation shape divergent light-harvesting strategies. 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=NakajimaYoshiki en-aut-sei=Nakajima en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakamotoRuna en-aut-sei=Sakamoto en-aut-mei=Runa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KumazawaMinoru en-aut-sei=Kumazawa en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IfukuKentaro en-aut-sei=Ifuku en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IshikawaTakahiro en-aut-sei=Ishikawa en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=TakabayashiAtsushi en-aut-sei=Takabayashi en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NagaoRyo en-aut-sei=Nagao en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Advanced Research Field, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Advanced Research Field, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Advanced Research Field, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Institute of Low Temperature Science, Hokkaido University kn-affil= affil-num=5 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=6 en-affil=Institute of Agricultural and Life Sciences, Academic Assembly, Shimane University kn-affil= affil-num=7 en-affil=Research Institute for Interdisciplinary Science, Advanced Research Field, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Institute of Low Temperature Science, Hokkaido University kn-affil= affil-num=9 en-affil=Faculty of Agriculture, Shizuoka University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=2 article-no= start-page=129 end-page=130 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=Exposure-induced mediator–outcome confounders in causal mediation: implications and visualisation en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=SuzukiEtsuji en-aut-sei=Suzuki en-aut-mei=Etsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShinozakiTomohiro en-aut-sei=Shinozaki en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamamotoEiji en-aut-sei=Yamamoto en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Interfaculty Initiative in Information Studies, the University of Tokyo kn-affil= affil-num=3 en-affil=Okayama University of Science kn-affil= END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=4 article-no= start-page=74 end-page= 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= kn-title=An Integrated QGIS-Based Evacuation Route Optimization Approach for Disaster Preparedness Against Urban Flood in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Urban inland flooding has become a serious problem in many cities because heavy rain often exceeds the capacity of drainage systems. 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=5 cd-vols= no-issue=6 article-no= start-page=660 end-page=671 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250914 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electronic Structure of the S1 State Manganese Cluster in Photosystem II Investigated Using Q-Band Selective Hole-Burning en-subtitle= kn-subtitle= en-abstract= kn-abstract=The electronic structure of the S1 state of photosystem II (PSII) was investigated using selective hole burning of Q-band pulsed electron paramagnetic resonance. The free induction decay and spin–echo signals of the tyrosine radical YD• in the plant PSII oscillated because of the magnetic dipole–dipole interaction with the S1 state Mn cluster. The initial period was 410 ns (2.44 MHz) and was assigned to the S = 1 spin state. Based on the oscillation analysis, both Mn1 and Mn4 and both Mn2 and Mn3 were assigned as Mn(III) and Mn(IV), respectively, which is consistent with the quantum chemical calculations. The 410 ns period was accounted for in the simplified model using the isotropic spin density distribution ratio [1.6:–1.1:–1.1:1.6] for Mn1–4 ions. This oscillation was identical with that observed in the presence of methanol. The oscillation decreased in PsbP/Q- and PsbO/P/Q-depleted PSII. In Thermosynechococcus vulcanus, two periods, 390 ns (2.56 MHz) and 630 ns (1.59 MHz), were detected, indicating that the cyanobacterial S1 state includes two isomers, S = 1 and S ≥ 2 spins. The S ≥ 2 spin was not detected in PsbO/U/V-depleted PSII without polyethylene glycol. The S ≥ 2 state was consistent with the reported quantum chemical calculation using S = 3. A simplified model accounted for the S = 1 state as the spin density distribution [1.8:–1.3:–1.3:1.8] and for the S ≥ 2 state as the isotropic spin density distribution [−0.5:0.5:0.5:0.5] for Mn1–4 ions. In combination with quantum chemical calculations, the most probable protonated structure is W1 = H2O, W2 = H2O, O4 = O2–, and O5 = O2– for the S1 state. These results demonstrate that the selective hole burning method is a powerful tool to complement X-ray studies to determine the valence and protonation structure of manganese clusters, not only in the S1 state but also in higher S-states and general metal clusters, which would provide important insights into the water oxidation mechanism. en-copyright= kn-copyright= en-aut-name=KosakiShinya en-aut-sei=Kosaki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamuraNaohiko en-aut-sei=Nakamura en-aut-mei=Naohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakajimaYoshiki en-aut-sei=Nakajima en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShenJian-Ren en-aut-sei=Shen en-aut-mei=Jian-Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MinoHiroyuki en-aut-sei=Mino en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Physics, Graduate School of Science, Nagoya University kn-affil= affil-num=2 en-affil=Department of Physics, Graduate School of Science, Nagoya University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Advanced Research Field, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Advanced Research Field, and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Department of Physics, Graduate School of Science, Nagoya University kn-affil= en-keyword=Photosystem II kn-keyword=Photosystem II en-keyword=Oxygen evolution kn-keyword=Oxygen evolution en-keyword=S1 state kn-keyword=S1 state en-keyword=Mn cluster kn-keyword=Mn cluster en-keyword=EPR kn-keyword=EPR en-keyword=Selective hole-burning kn-keyword=Selective hole-burning END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=5 article-no= start-page=101 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=Prolonged exposure to axitinib alters the molecular profile of Caki‑2 renal cell carcinoma cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Axitinib, an oral second‑generation multitargeted tyrosine kinase inhibitor, is used as a second‑line treatment for metastatic renal cell carcinoma (RCC). However, patients often develop resistance after initial responsiveness, necessitating the elucidation of the underlying resistance mechanisms. Therefore, the present study aimed to investigate the mechanisms underlying axitinib resistance using the Caki‑2 human papillary RCC model cells. Cells tolerating 0.1 µM axitinib were designated as Caki/AX cells. Cell viability was assessed using the water‑soluble tetrazolium salt assay. Notably, the 50% inhibitory concentration (IC50) values of axitinib and sunitinib were significantly higher in Caki/AX cells than those in Caki‑2 cells, indicating 2.83‑ and 1.2‑fold resistance, respectively. By contrast, the IC50 values of sorafenib and erlotinib were decreased in Caki/AX cells. Moreover, Caki/AX cells showed resistance to everolimus, temsirolimus and rapamycin, and decreased sensitivity to vinblastine, vincristine, paclitaxel, doxorubicin and SN‑38 compared with Caki‑2 cells. Notably, etoposide, 5‑fluorouracil, cisplatin and carboplatin sensitivities were comparable in both cell types. Reverse transcription‑quantitative polymerase chain reaction (PCR) analysis revealed that the mRNA levels of the ATP‑binding cassette subfamily B member 1 and subfamily G member 2 were significantly higher in Caki/AX cells than those in Caki‑2 cells. A PCR array related to vascular endothelial growth factor signalling showed that the mRNA levels of FIGF (also known as vascular endothelial growth factor D) and sphingosine kinase 1 were upregulated, whereas those of Rac family small GTPase 2 were downregulated in Caki/AX cells. Overall, these findings suggested that the upregulation of the ATP‑binding cassette subfamily B member 1, FIGF and sphingosine kinase 1 mRNA levels, and downregulation of the Rac family small GTPase 2 mRNA levels may contribute to acquired resistance in Caki/AX cells. en-copyright= kn-copyright= en-aut-name=NakayamaYuko en-aut-sei=Nakayama en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=InoAya en-aut-sei=Ino en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=TakaraKohji en-aut-sei=Takara en-aut-mei=Kohji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Clinical Pharmaceutics, Faculty of Pharmaceutical Sciences, Himeji Dokkyo University kn-affil= affil-num=2 en-affil=Department of Pharmaceutics and Pharmaceutical Technology, Faculty of Pharmaceutical Sciences, Hyogo Medical University kn-affil= affil-num=3 en-affil=Department of Integrated Clinical and Basic Pharmaceutical Sciences, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pharmaceutics and Pharmaceutical Technology, Faculty of Pharmaceutical Sciences, Hyogo Medical University kn-affil= en-keyword=axitinib kn-keyword=axitinib en-keyword=renal cell carcinoma kn-keyword=renal cell carcinoma en-keyword=drug resistance kn-keyword=drug resistance en-keyword=ABC transporter kn-keyword=ABC transporter 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=20251229 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genotype–Phenotype Correlations of Li–Fraumeni Syndrome in Japan Children's Cancer Group LFS20 Study Cohort en-subtitle= kn-subtitle= en-abstract= kn-abstract=Li–Fraumeni syndrome (LFS) is a cancer predisposition syndrome caused by germline pathogenic variants in the TP53 gene. With the increasing use of multi-gene panel testing, TP53 variants have been identified in individuals who do not meet established TP53 testing criteria, such as the Chompret criteria. The term “attenuated LFS” has been proposed for some of these cases, particularly those with adult-onset cancer. We analyzed participants of the Japanese nationwide prospective clinical trial of the cancer surveillance program (Japan Children's Cancer Group LFS-20), along with clinical information including their family histories, to better understand their genotypic and phenotypic characteristics. We identified 32 distinct TP53 variants from 41 families (45 participants), including four missense variants with conflicting classifications of pathogenicity in ClinVar. Among these families, 36 (88%) met the LFS criteria (hereafter referred to as “LFS” in contrast to attenuated LFS), while 5 (12%) were classified as attenuated LFS. Including 30 additional family members carrying the same variant, we analyzed 75 individuals with TP53 variants. Of these, 40 with LFS and 6 with attenuated LFS had cancer. Multiple primary cancers occurred in 22 individuals (21 LFS, 1 attenuated LFS). LFS-core tumors accounted for 66% (58/88) of cancers in the LFS group and 63% (5/8) in the attenuated LFS group; of note, all core tumors in the attenuated group were limited to breast cancer. Hotspot missense variants were detected in 11 of 36 LFS families and in none of 5 attenuated LFS families, and non-hotspot null variants were found in 14 and 1, respectively. Our study revealed genotype–phenotype correlations in several respects.

These trials reported 12-month overall survival (OS) rates of 60%–67% with atezolizumab combination therapy. J-TAIL-2 (NCT04501497), a prospective, multicenter, observational study, evaluated atezolizumab combination therapy in routine clinical practice in Japan. Patients ≥ 20 years old with NSCLC received atezolizumab plus carboplatin and nab-paclitaxel (atezo + CnP), atezolizumab plus carboplatin or cisplatin plus pemetrexed (atezo + PP), or atezolizumab plus bevacizumab plus carboplatin and paclitaxel (atezo + bev + CP) in clinical practice. The primary endpoint was the 12-month OS rate. Secondary endpoints included OS, progression-free survival, and subgroup analyses, including IMpower-unlike (did not meet the main eligibility criteria of each IMpower trial) and IMpower-like patients. In total, 814 patients were enrolled (atezo + CnP, n = 217; atezo + PP, n = 211; atezo + bev + CP, n = 386). The IMpower-unlike group included patients with Eastern Cooperative Oncology Group performance status ≥ 2, autoimmune disease, or interstitial lung disease. Twelve-month OS rates (95% confidence interval [CI]) were 62.9% (55.8–69.2), 72.1% (65.2–77.9), and 68.3% (63.2–72.9) with atezo + CnP, atezo + PP, and atezo + bev + CP, respectively. OS hazard ratios (95% CI) in the IMpower-unlike vs. -like subgroups were 1.36 (0.91–2.05), 1.08 (0.70–1.68), and 1.49 (1.09–2.06), respectively. No new safety signals were observed. Real-world efficacy and safety for each atezolizumab combination were comparable to those in the relevant IMpower trials. en-copyright= kn-copyright= en-aut-name=YoshiokaHiroshige en-aut-sei=Yoshioka

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

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=30 cd-vols= no-issue=7 article-no= start-page=oyaf201 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=Pharmacovigilance study for the identification of mogamulizumab-induced immune-related adverse events using a real-world database en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Mogamulizumab is a humanized anti-CCR4 monoclonal antibody used for relapsed/refractory adult T-cell leukemia, cutaneous T-cell lymphoma, and/or Sézary syndrome. Reports of immune-related adverse events (irAEs) in these patients are increasing, and the association between irAEs and mogamulizumab remains to be elucidated. This study aimed to evaluate the association between mogamulizumab and immune-related adverse events (irAEs), as well as to characterize the irAEs associated with mogamulizumab using data from a large-scale spontaneous reporting system.
Methods: We performed an exploratory hypothesis-generating analysis of patients from 1967 to September 2023 using VigiBase, a World Health Organization spontaneous adverse event reporting system database. We performed a disproportionality analysis and determined the reporting odds ratios and information components between the drugs of interest and each irAE.
Results: Mogamulizumab was associated with some irAEs, including myocarditis, severe cutaneous adverse reactions, hepatitis, and myositis. Mogamulizumab exhibited significantly higher reporting rates of these 4 irAEs compared to the anticancer agents other than mogamulizumab. Conversely, the reporting rate of other irAEs, including endocrine autoimmune diseases induced by immune checkpoint inhibitors, was not significant in patients who received mogamulizumab.
Conclusions: Mogamulizumab is associated with irAEs, including myocarditis, severe cutaneous adverse reactions, hepatitis, and myositis. en-copyright= kn-copyright= en-aut-name=MiyataKoji en-aut-sei=Miyata en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Izawa-IshizawaYuki en-aut-sei=Izawa-Ishizawa en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NiimuraTakahiro en-aut-sei=Niimura en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshiokaToshihiko en-aut-sei=Yoshioka en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HyodoMizusa en-aut-sei=Hyodo en-aut-mei=Mizusa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ItokazuShuto en-aut-sei=Itokazu en-aut-mei=Shuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyataTatsumi en-aut-sei=Miyata en-aut-mei=Tatsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AizawaFuka en-aut-sei=Aizawa en-aut-mei=Fuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YagiKenta en-aut-sei=Yagi en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KawadaKei en-aut-sei=Kawada en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HamanoHirofumi en-aut-sei=Hamano en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= en-aut-name=GodaMitsuhiro en-aut-sei=Goda en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=IshizawaKeisuke en-aut-sei=Ishizawa en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=2 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=3 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=4 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=5 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=6 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=7 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=8 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=9 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=10 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=11 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=14 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= en-keyword=irAEs kn-keyword=irAEs en-keyword=mogamulizumab kn-keyword=mogamulizumab en-keyword=VigiBase kn-keyword=VigiBase en-keyword=disproportionality analysis kn-keyword=disproportionality analysis en-keyword=sézary syndrome kn-keyword=sézary syndrome END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=2 article-no= start-page=100820 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=Feasibility and Diagnostic Utility of Mucosal T-Cell Flow Cytometry for Intestinal Graft-Versus-Host Disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Aims: Timely diagnosis of intestinal complications after hematopoietic stem cell transplantation (HSCT), including graft-versus-host disease (GVHD), transplant-associated thrombotic microangiopathy, and cytomegalovirus infection, is essential for appropriate management. This study evaluated whether mucosal T-cell profiling from endoscopic biopsies could support the diagnosis of these post-transplant conditions.
Methods: We prospectively analyzed 58 intestinal biopsy specimens from 21 post-HSCT patients. Paired samples were obtained from the stomach and duodenum during upper endoscopy and from the ileum and large intestine during colonoscopy. Lymphocytes were isolated from each specimen and analyzed using flow cytometry. These data were integrated with those of a previously collected cohort (35 patients, 51 samples) for comparative immunophenotypic analysis across histologically defined groups.
Results: Duodenal biopsies yielded more lymphocytes than did gastric biopsies (mean ± standard deviation: 532 ± 823 vs 233 ± 392 cells; P = .070), with comparable yields between the ileum and colon. Among 41 evaluable cases, the CD56+:CD3+ ratio was significantly lower in patients with GVHD (5.5 ± 2.2%) than in those with nonspecific or no inflammation (28.4 ± 16.3%; P = .006). A cutoff value of <11% provided 85.7% sensitivity and 83.3% specificity for diagnosing GVHD (area under the curve = 0.91).
Conclusion: Mucosal T-cell profiling using endoscopic biopsies is feasible and may aid in the diagnosis of GVHD after HSCT. A decreased CD56+:CD3+ ratio is a promising marker for distinguishing GVHD from other post-transplant intestinal conditions. 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=KondoTakumi en-aut-sei=Kondo en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 ORCID= en-aut-name=HiramatsuMai en-aut-sei=Hiramatsu en-aut-mei=Mai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HirabataAraki en-aut-sei=Hirabata en-aut-mei=Araki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakahashiTakahide en-aut-sei=Takahashi en-aut-mei=Takahide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= 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= 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 Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Division of Medical Support, Okayama University Hospital kn-affil= affil-num=6 en-affil=Division of Medical Support, Okayama University Hospital kn-affil= affil-num=7 en-affil=Division of Medical Support, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=cytomegalovirus infection kn-keyword=cytomegalovirus infection en-keyword=flow cytometry kn-keyword=flow cytometry en-keyword=graft-versus-host disease kn-keyword=graft-versus-host disease en-keyword=hematopoietic stem cell transplantation kn-keyword=hematopoietic stem cell transplantation en-keyword=T lymphocytes kn-keyword=T lymphocytes END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=376 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Oral Health-Related Quality of Life and Self-Reported Oral Health Status Are Associated with Change in Self-Reported Depression Status: A Cohort Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Oral health-related quality of life (OHRQoL) may influence mental health outcomes, yet longitudinal evidence on its association with depression remains limited. 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=16 cd-vols= no-issue=1 article-no= start-page=45 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=Magnetic Detection of Cancer Cells Using Tumor-Homing Peptide-Modified Magnetic Nanoparticles en-subtitle= kn-subtitle= en-abstract= kn-abstract=Magnetic nanoparticles (MNPs) provide a platform for target detection because of their magnetic responsiveness to alternating magnetic fields (AMFs). We developed a detection method using MNPs modified with tumor-homing peptides (THPs), PL1 and PL3, which selectively bind to protein components enriched in malignant tissues. THP-MNPs were synthesized using maleimide-PEG-NHS linkers and characterized using transmission electron microscopy. Human glioblastoma cancer U87MG and normal tissue-derived HEK293 cells were incubated with THP-MNPs, and the magnetic signals were measured using a high-temperature superconducting quantum interference device (SQUID) magnetometer under an AMF (1.06 kHz). Dark-field microscopy confirmed the preferential binding of THP-MNPs to U87MG cells. In the absence of cells, THP-MNPs exhibited AMF-dependent signal enhancement, which correlated with particle size reduction due to THP release. This increase was completely suppressed in the presence of U87MG cells, indicating a strong THP-mediated interaction. PL3-MNPs exhibited superior discrimination between malignant and non-malignant cells. These results demonstrate that SQUID-based magnetic measurements using THP-MNPs enable rapid and label-free cancer cell detection. en-copyright= kn-copyright= en-aut-name=ZhouShengli en-aut-sei=Zhou en-aut-mei=Shengli kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurutaniYuji en-aut-sei=Furutani en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamashitaKei en-aut-sei=Yamashita en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KakoSakuya en-aut-sei=Kako en-aut-mei=Sakuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WatanabeKazunori en-aut-sei=Watanabe en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KiwaToshihiko en-aut-sei=Kiwa en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OhtsukiTakashi en-aut-sei=Ohtsuki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=7 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=magnetic nanoparticle kn-keyword=magnetic nanoparticle en-keyword=tumor-homing peptide kn-keyword=tumor-homing peptide en-keyword=superconducting quantum interference devices kn-keyword=superconducting quantum interference devices 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.

This study aimed to evaluate the clinical significance of switching CDK4/6i + ET in a large real-world cohort. Using a medical database, we identified 13,284 patients with hormone receptor–positive/human epidermal growth factor receptor 2–negative advanced breast cancer who received CDK4/6i + ET between 2008 and 2022. Patients were categorized into five groups based on their first- and second-line therapy patterns. We compared the median time to discontinuation (TTD) among the groups. In patients who switched from one CDK4/6i + ET to another CDK4/6i + ET, the second-line TTD and total TTD of first- and second-line therapies (n = 542) were significantly longer than those in patients who switched from CDK4/6i + ET to ET monotherapy (n = 490) (the second-line TTD: 11.2 vs. 4.9 months, p < 0.01; total TTD: 25.1 vs. 20.5 months, p < 0.01). The order of palbociclib and abemaciclib administration did not significantly affect the second-line or total TTD in patients who switched from one CDK4/6i + ET to another CDK4/6i + ET. Switching from one CDK4/6i + ET to another CDK4/6i + ET resulted in a significantly longer TTD than switching to ET monotherapy. Considering the phase III clinical trial results of capivasertib, switching to CDK4/6i + ET is a viable therapeutic option regardless of the PIK3CA mutation status. en-copyright= kn-copyright= en-aut-name=NishinaTakuya en-aut-sei=Nishina en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TaniokaMaki en-aut-sei=Tanioka en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakadaKenji en-aut-sei=Takada en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsukiokiTakahiro en-aut-sei=Tsukioki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahashiYuko en-aut-sei=Takahashi en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=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= affil-num=1 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Medical AI Project, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Cyclin-dependent kinase 4/6 inhibitors kn-keyword=Cyclin-dependent kinase 4/6 inhibitors en-keyword=Endocrine therapy kn-keyword=Endocrine therapy en-keyword=HR-positive/HER2-negative advanced breast cancer kn-keyword=HR-positive/HER2-negative advanced breast cancer en-keyword=Progression-free survival kn-keyword=Progression-free survival en-keyword=Time to discontinuation kn-keyword=Time to discontinuation END start-ver=1.4 cd-journal=joma no-vol=36 cd-vols= no-issue= article-no= start-page=100857 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=A multi-institutional dummy run on segmentation variability and plan quality of stereotactic body radiotherapy for oligometastatic disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and purpose: Oligometastatic disease represents limited metastatic burden, and local ablative therapies such as stereotactic body radiotherapy (SBRT) may improve survival. 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=75 cd-vols= no-issue=1 article-no= start-page=13 end-page=19 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= kn-title=自然起源放射性物質(NORM)を用いた232Th/212Pbジェネレーターによる短寿命放射性核種の作製—非密封放射性同位元素の安全取扱実習への応用— en-subtitle= kn-subtitle= en-abstract= kn-abstract=我々は自然起源放射性物質(NORM)を放射線源とする232Th/212Pbジェネレーターを作製した。ジェネレーターから室温で約500 Bqの高純度の212Pbをミルキングできた。これを用いて32Pを用いた非密封放射性同位元素の安全取扱実習を置き換えることができることを示した。ジェネレーターの作製の容易さ,ミルキング操作の簡便性,212Pb及びその子孫核種の放射性同位元素としての特性から,今回作製した232Th/212Pbジェネレーターは放射線教育に有効に活用できると結論した。 en-copyright= kn-copyright= en-aut-name=ImadaYui en-aut-sei=Imada en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IsobeMidori en-aut-sei=Isobe en-aut-mei=Midori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TeratoHiroaki en-aut-sei=Terato en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HanafusaTadashi en-aut-sei=Hanafusa en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Advanced Science Research Center, Okayama University kn-affil= affil-num=2 en-affil=Advanced Science Research Center, Okayama University kn-affil= affil-num=3 en-affil=Advanced Science Research Center, Okayama University kn-affil= affil-num=4 en-affil=Advanced Science Research Center, Okayama University kn-affil= en-keyword=lead-212 kn-keyword=lead-212 en-keyword=radioisotope generator kn-keyword=radioisotope generator en-keyword=safe handling training kn-keyword=safe handling training en-keyword=unsealed radioisotope kn-keyword=unsealed radioisotope END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue= article-no= start-page=6009610 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=Small Distance Increment Method for Measuring Complex Permittivity With mmWave Radar en-subtitle= kn-subtitle= en-abstract= kn-abstract=Measuring the complex permittivity of material is essential in many scenarios, such as quality checks in material manufacturing. 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=93 cd-vols= no-issue= article-no= start-page=102631 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Detection of the nuclear translocation of androgen receptor using quantitative and automatic cell imaging analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Testosterone signaling mediates diseases such as androgenetic alopecia and prostate cancer and is controlled by the activation of the androgen receptor (AR) and nuclear translocation of the ligand-receptor complex.

The cells expressed the histone H2B protein as visualized using a red fluorescence marker, enabling the Detection of nuclear translocation under live cell conditions using image analysis. The AR was observed to be translocated from the cytoplasm to the nucleus of cells after stimulation with dihydrotestosterone (DHT). The signal intensity of the nuclear/cytoplasm ratio was analyzed using automatic image analysis and a newly developed algorithm. The quantitation method to detect nuclear translocation revealed that the AR nuclear signal plateaued approximately 20 min after DHT exposure. Our developed method has the potential to save human labor by the automatic process of the image. en-copyright= kn-copyright= en-aut-name=BaiLanlan en-aut-sei=Bai en-aut-mei=Lanlan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WuTao en-aut-sei=Wu en-aut-mei=Tao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukasawaMizuki en-aut-sei=Fukasawa en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KashiwagiSayo en-aut-sei=Kashiwagi en-aut-mei=Sayo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TateHaruka en-aut-sei=Tate en-aut-mei=Haruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OzakiTaku en-aut-sei=Ozaki en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuganoEriko en-aut-sei=Sugano en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TomitaHiroshi en-aut-sei=Tomita en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IshiiTsuyoshi en-aut-sei=Ishii en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AkashiTakuya en-aut-sei=Akashi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FukudaTomokazu en-aut-sei=Fukuda en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Graduate School of Science and Engineering, Iwate University kn-affil= affil-num=2 en-affil=Graduate School of Science and Engineering, Iwate University kn-affil= affil-num=3 en-affil=Neuro-AI Integration Science Laboratory, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Rohto Pharmaceutical Co., Ltd., Basic Research Development Division kn-affil= affil-num=5 en-affil=Graduate School of Science and Engineering, Iwate University kn-affil= affil-num=6 en-affil=Graduate School of Science and Engineering, Iwate University kn-affil= affil-num=7 en-affil=Graduate School of Science and Engineering, Iwate University kn-affil= affil-num=8 en-affil=Graduate School of Science and Engineering, Iwate University kn-affil= affil-num=9 en-affil=Rohto Pharmaceutical Co., Ltd., Basic Research Development Division kn-affil= affil-num=10 en-affil=Neuro-AI Integration Science Laboratory, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Science and Engineering, Iwate University kn-affil= en-keyword=Dermal papilla cell kn-keyword=Dermal papilla cell en-keyword=Nuclear translocation kn-keyword=Nuclear translocation en-keyword=Androgen receptor kn-keyword=Androgen receptor en-keyword=Live cell imaging kn-keyword=Live cell imaging en-keyword=Digital image analysis kn-keyword=Digital image analysis en-keyword=Quantitation algorithm kn-keyword=Quantitation algorithm END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=1 article-no= start-page=10 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=Gut microbial metabolite butyrate boosts p53-expressing telomerase-specific oncolytic adenovirus efficacy by enhancing infectivity and activating MHC-I/cGAS-STING en-subtitle= kn-subtitle= en-abstract= kn-abstract=The gut microbiota plays an essential role in regulating host immunity, and its metabolites such as butyrate exert immunomodulatory effects by acting as histone deacetylase inhibitors. Oncolytic virotherapy has emerged as a promising approach for cancer treatment, and we have developed OBP-702, a telomerase-specific oncolytic adenovirus that expresses p53 and elicits strong systemic antitumor responses. In this study, the potential synergy between butyrate and OBP-702 was investigated in colorectal cancer models. Using human and murine colorectal carcinoma cell lines, butyrate was found to directly enhance the infectivity of OBP-702 by upregulating CAR and integrins, thereby promoting apoptosis and autophagy in tumor cells. In addition, butyrate indirectly boosted systemic antitumor immunity by upregulating MHC-I expression through activation of the cGAS-STING pathway and enhancing CD8 + T cell recruitment via CXCL10 secretion. These findings were supported by in vivo experiments using CT26 subcutaneous, bilateral, and orthotopic tumor models, in which the combination of oral butyrate and intratumoral OBP-702 administration produced synergistic antitumor effects. These results highlight the therapeutic potential of integrating gut microbial metabolites with oncolytic virotherapy as a novel immunotherapeutic strategy for colorectal cancer. en-copyright=

en-title= kn-title=A Spectrum Allocation and Security-Sensitive Task Offloading Algorithm in MEC Using DVS en-subtitle= kn-subtitle= en-abstract= kn-abstract=With the advancements of the next-generation communication networking and Internet of Things (IoT) technologies, a variety of computation-intensive applications (e.g., autonomous driving and face recognition) have emerged. The execution of these IoT applications demands a lot of computing resources. Nevertheless, terminal devices (TDs) usually do not have sufficient computing resources to process these applications. Offloading IoT applications to be processed by mobile edge computing (MEC) servers with more computing resources provides a promising way to address this issue. While a significant number of works have studied task offloading, only a few of them have considered the security issue. This study investigates the problem of spectrum allocation and security-sensitive task offloading in an MEC system. Dynamic voltage scaling (DVS) technology is applied by TDs to reduce energy consumption and computing time. To guarantee data security during task offloading, we use AES cryptographic technique. The studied problem is formulated as an optimization problem and solved by our proposed efficient offloading scheme. The simulation results show that the proposed scheme can reduce system cost while guaranteeing data security. en-copyright= kn-copyright= en-aut-name=LiXianwei en-aut-sei=Li en-aut-mei=Xianwei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=YangXiaoying en-aut-sei=Yang en-aut-mei=Xiaoying kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TolbaAmr en-aut-sei=Tolba en-aut-mei=Amr kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ZengZijian en-aut-sei=Zeng en-aut-mei=Zijian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AlfarrajOsama en-aut-sei=Alfarraj en-aut-mei=Osama kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=School of Computer and Information Engineering, Bengbu University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=School of Information Engineering, Suzhou University kn-affil= affil-num=4 en-affil=Computer Science and Engineering Department, College of Applied Studies, King Saud University kn-affil= affil-num=5 en-affil=Institute of Computer Science and Digital Innovation, UCSI University kn-affil= affil-num=6 en-affil=Computer Science and Engineering Department, College of Applied Studies, King Saud University kn-affil= en-keyword=IoT kn-keyword=IoT en-keyword=DVS kn-keyword=DVS en-keyword=MEC kn-keyword=MEC en-keyword=AES kn-keyword=AES END start-ver=1.4 cd-journal=joma no-vol=137 cd-vols= no-issue=3 article-no= start-page=149 end-page=149 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=The 19th Annual Meeting of Japanese Association of Medical Technology Education kn-title=第19回日本臨床検査学教育学会学術大会 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HirohataSatoshi en-aut-sei=Hirohata en-aut-mei=Satoshi kn-aut-name=廣畑聡 kn-aut-sei=廣畑 kn-aut-mei=聡 aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Medical Technology, Faculty of Health Sciences, Okayama University kn-affil=岡山大学学術研究院保健学域 検査技術科学 END start-ver=1.4 cd-journal=joma no-vol=137 cd-vols= no-issue=3 article-no= start-page=132 end-page=136 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=Advances in and future perspectives on robot-assisted surgery in the field of thoracic surgery kn-title=呼吸器外科領域におけるロボット支援手術の進化と展望 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name=岡﨑幹生 kn-aut-sei=岡﨑 kn-aut-mei=幹生 aut-affil-num=1 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name=豊岡伸一 kn-aut-sei=豊岡 kn-aut-mei=伸一 aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, 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 呼吸器・乳腺内分泌学 affil-num=2 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, 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 呼吸器・乳腺内分泌学 en-keyword=ロボット支援下手術 kn-keyword=ロボット支援下手術 en-keyword=RATS kn-keyword=RATS END start-ver=1.4 cd-journal=joma no-vol=137 cd-vols= no-issue=3 article-no= start-page=118 end-page=125 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=The results of COVID-19 antibody testing studies in Bizen, Japan kn-title=備前市における新型コロナウイルス感染症の抗体検査に関する研究の成果報告 en-subtitle= kn-subtitle= en-abstract= kn-abstract= We conducted two prospective cohort studies (June 2022–March 2023 and Nov 2023–Jan 2024) of 1,899 and 445 residents and other individuals who are affiliated with institutions in the city of Bizen in Japan's Okayama prefecture (population 32,320 as of 2020).

Laser welding of copper and aluminum is required, and there are some reports to weld copper and aluminum firmly by laser irradiation from the aluminum side. On the other hand, laser irradiation from the copper side requires high power density to generate a keyhole, which causes the strong convection of molten aluminum into copper. Thus, brittle intermetallic compounds with rich aluminum result in the deterioration of joining strength. Angled laser irradiation enables mild heat input to the aluminum side, and the combination of angled and superposed irradiation of blue and near-infrared (NIR) lasers achieved a remarkable increase of breaking strength. However, the breaking strength is still lower than the base materials. Therefore, insert materials between copper and aluminum plates were investigated by the angled irradiation of blue and NIR lasers from the copper side. The breaking strength with insert materials showed higher values in the order of titanium mesh, nickel foil, and nickel mesh, and its value with the nickel mesh was close to the tensile strength of aluminum in a cross tensile test. Further improvement of breaking strength is possible by inserting the nickel mesh between copper and aluminum plates in the case of angled irradiation of blue and NIR lasers even from the copper side. en-copyright= kn-copyright= en-aut-name=OkamotoYasuhiro en-aut-sei=Okamoto en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamadaYuki en-aut-sei=Yamada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkadaAkira en-aut-sei=Okada en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyakeMasaki en-aut-sei=Miyake en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamuraTakeshi en-aut-sei=Yamamura en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NagasakiKatsutoshi en-aut-sei=Nagasaki en-aut-mei=Katsutoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishiNorio en-aut-sei=Nishi en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Kataoka Corporation kn-affil= affil-num=5 en-affil=Kataoka Corporation kn-affil= affil-num=6 en-affil=Kataoka Corporation kn-affil= affil-num=7 en-affil=Kataoka Corporation kn-affil= en-keyword=welding kn-keyword=welding en-keyword=copper kn-keyword=copper en-keyword=aluminum kn-keyword=aluminum en-keyword=insert metal kn-keyword=insert metal en-keyword=intermetallic compound kn-keyword=intermetallic compound en-keyword=fiber laser kn-keyword=fiber laser en-keyword=blue laser kn-keyword=blue laser en-keyword=angled irradiation kn-keyword=angled irradiation END
