To evaluate the possibility of combined utilization of a certain compound to overcome this resistance, we focused on glutathione S-transferase (GST)-dependent metabolism of BITC. The pharmacological treatment of a pi-class GST-selective inhibitor, 6-(7-nitro-2,1,3-benzoxadiazol-4-ylthio)hexanol (NBDHEX), significantly increased BITC-induced toxicity in human colorectal cancer HCT-116 cells. However, NBDHEX unexpectedly increased the level of the BITC?glutathione (GSH) conjugate as well as BITC-modified proteins, suggesting that NBDHEX might increase BITC-modified protein accumulation by inhibiting BITC?GSH excretion instead of inhibiting GST. Furthermore, NBDHEX significantly potentiated BITC-induced apoptosis with the enhanced activation of apoptosis-related pathways, such as c-Jun N-terminal kinase and caspase-3 pathways. These results suggested that combination treatment with NBDHEX may be an effective way to overcome MDR with drug efflux and thus induce the biological activity of BITC at lower doses. en-copyright= kn-copyright= en-aut-name=SunRuitong en-aut-sei=Sun en-aut-mei=Ruitong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YanoAina en-aut-sei=Yano en-aut-mei=Aina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatohAyano en-aut-sei=Satoh en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=NakamuraToshiyuki en-aut-sei=Nakamura en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=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 Interdisciplinary Science and Engineering in Health Systems, 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=benzyl isothiocyanate kn-keyword=benzyl isothiocyanate en-keyword=multidrug resistance kn-keyword=multidrug resistance en-keyword=glutathione S-transferase kn-keyword=glutathione S-transferase en-keyword=NBDHEX kn-keyword=NBDHEX en-keyword=apoptosis kn-keyword=apoptosis en-keyword=c-Jun N-terminal kinase kn-keyword=c-Jun N-terminal kinase END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=113544 end-page=113556 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250630 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Optimized Ensemble Deep Learning for Real-Time Intrusion Detection on Resource-Constrained Raspberry Pi Devices en-subtitle= kn-subtitle= en-abstract= kn-abstract=The rapid growth of Internet of Things (IoT) networks has increased security risks, making it essential to have effective Intrusion Detection Systems (IDS) for real-time threat detection. Deep learning techniques offer promising solutions for such detection due to their superior complex pattern recognition and anomaly detection capabilities in large datasets. This paper proposes an optimized ensemble-based IDS designed specifically for efficient deployment on edge hardware. However, deploying such computationally intensive models on resource-limited edge devices remains a significant challenge due to model size and computational overhead on devices with limited processing capabilities. Building upon our previously developed stacked Long Short-Term Memory (LSTM) model integrated with ANOVA feature selection, we optimize it by integrating dual-stage model compression: pruning and quantization to create a lightweight model suitable for real-time inference on Raspberry Pi devices. To evaluate the system under realistic conditions, we combined with a Kafka-based testbed to simulate dynamic IoT environments with variable traffic loads, delays, and multiple simultaneous attack sources. This enables the assessment of detection performance under varying traffic volumes, latency, and overlapping attack scenarios. The proposed system maintains high detection performance with accuracy of 97.3% across all test scenarios, while efficiently leveraging multi-core processing with peak CPU usage reaching 111.8%. These results demonstrate the system’s practical viability for real-time IoT security at the edge. en-copyright= kn-copyright= 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=1 ORCID= en-aut-name=HudaSamsul en-aut-sei=Huda en-aut-mei=Samsul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NguyenTuy Tan en-aut-sei=Nguyen en-aut-mei=Tuy Tan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Interdisciplinary Education and Research Field, Okayama University kn-affil= affil-num=3 en-affil=School of Informatics, Computing, and Cyber Systems, Northern Arizona 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= en-keyword=Internet of things kn-keyword=Internet of things en-keyword=intrusion detection system kn-keyword=intrusion detection system en-keyword=stacked lstm kn-keyword=stacked lstm en-keyword=pruning model kn-keyword=pruning model en-keyword=optimizing model kn-keyword=optimizing model en-keyword=quantization model kn-keyword=quantization model en-keyword=raspberry pi kn-keyword=raspberry pi en-keyword=real-time detection kn-keyword=real-time detection en-keyword=apache kafka kn-keyword=apache kafka END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=89003 end-page=89024 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250519 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Security in Post-Quantum Era: A Comprehensive Survey on Lattice-Based Algorithms en-subtitle= kn-subtitle= en-abstract= kn-abstract=Lattice-based post-quantum cryptography (PQC) has attracted significant attention as a promising solution to the security challenges posed by quantum computing. Unlike traditional cryptographic algorithms, lattice-based schemes are expected to remain secure even in the presence of quantum attacks, making them essential for securing future data. Despite their strong theoretical foundations, lattice-based schemes face several practical challenges, particularly in optimizing performance and scalability for real-world applications. This survey provides a novel taxonomy that categorizes lattice-based PQC designs, with an emphasis on computational paradigms and security considerations. We systematically evaluate lattice-based PQC implementations across both software platforms, including central processing units and graphics processing units, as well as hardware platforms like field-programmable gate arrays and application-specific integrated circuits, highlighting their strengths and limitations. In addition, we explore the practical applications of lattice-based cryptography in fields such as secure communication, critical infrastructure, privacy-preserving data analytics, artificial intelligence, and trust and authentication systems. By offering a comprehensive overview of the current state of lattice-based PQC, this survey aims to provide valuable insights into the ongoing advancements and future research directions in the field as we transition to a post-quantum era. en-copyright= kn-copyright= en-aut-name=NguyenHien en-aut-sei=Nguyen en-aut-mei=Hien kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HudaSamsul en-aut-sei=Huda en-aut-mei=Samsul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NogamiYasuyuki en-aut-sei=Nogami en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NguyenTuy Tan en-aut-sei=Nguyen en-aut-mei=Tuy Tan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=School of Informatics, Computing, and Cyber Systems, Northern Arizona University kn-affil= affil-num=2 en-affil=Interdisciplinary Education and Research Field, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=School of Informatics, Computing, and Cyber Systems, Northern Arizona University kn-affil= en-keyword=Post-quantum cryptography kn-keyword=Post-quantum cryptography en-keyword=lattice-based cryptography kn-keyword=lattice-based cryptography en-keyword=number theoretic transform kn-keyword=number theoretic transform en-keyword=hardware and software implementation kn-keyword=hardware and software implementation END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=17 article-no= start-page=1305 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250822 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Discovery and Functional Characterization of Novel Aquaporins in Tomato (Solanum lycopersicum): Implications for Ion Transport and Salinity Tolerance en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aquaporins (AQPs) are membrane proteins that facilitate the transport of water and solutes. Among AQPs, plasma membrane intrinsic proteins (PIPs) play a critical role in maintaining water balance between the internal and external cell environments. This study focuses on the tomato due to its economic importance and cultivation under moderate salinity conditions in Japan. A swelling assay using X. laevis oocyte confirmed that all five examined tomato SlPIP2 isoforms showed water transport activity. Among them, two-electrode voltage clamp (TEVC) experiments showed that only SlPIP2;1, SlPIP2;4, and SlPIP2;8 transport Na+ and K+, with no transport activity for Cs+, Rb+, Li+, or Cl?. CaCl2 (1.8 mM) reduced ionic currents by approximately 45% compared to 30 ?M free-Ca2+. These isoforms function as very low-affinity Na+ and K+ transporters. Expression analysis showed that SlPIP2;4 and SlPIP2;8 had low, stable expression, while SlPIP2;1 was strongly upregulated in roots NaCl treatment (200 mM, 17days), suggesting distinct physiological roles for these ion-conducting AQPs (icAQPs). These data hypothesized that tomato icAQPs play a critical role in ion homeostasis, particularly under salinity stress. In conclusion, the first icAQPs have been identified in the dicotyledonous crop. These icAQPs are essential for plant resilience under salt stress. en-copyright= kn-copyright= en-aut-name=PaulNewton Chandra en-aut-sei=Paul en-aut-mei=Newton Chandra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ImranShahin en-aut-sei=Imran en-aut-mei=Shahin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitsumotoAnri en-aut-sei=Mitsumoto en-aut-mei=Anri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriIzumi C. en-aut-sei=Mori en-aut-mei=Izumi C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatsuharaMaki en-aut-sei=Katsuhara en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Aquaporin (AQP) kn-keyword=Aquaporin (AQP) en-keyword=ion transport kn-keyword=ion transport en-keyword=plasma membrane intrinsic proteins (PIPs) kn-keyword=plasma membrane intrinsic proteins (PIPs) en-keyword=tomato kn-keyword=tomato en-keyword=oocytes kn-keyword=oocytes en-keyword=water transport kn-keyword=water transport END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=24040 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250705 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lactose fermenting enteroinvasive Escherichia coli from diarrhoeal cases confers enhanced virulence en-subtitle= kn-subtitle= en-abstract= kn-abstract=Enteroinvasive Escherichia coli (EIEC), known for causing bacillary dysentery akin to Shigella species, comprises both lactose-fermenting (LF) and non-lactose-fermenting (NLF) isolates. While NLF-EIEC is a well-established pathogen associated with acute dysentery and harbours classical Shigella-like virulence factors, the role of LF-EIEC in human disease remains underexplored. In this study, we sought to characterize LF-EIEC clinical isolates and assessed their pathogenic potential in comparison to NLF-EIEC. Among 13,682 diarrhoeal stool specimens, six LF and nine NLF-EIEC were isolated, predominantly belonging to serogroups O28ac, O125, O136, and O152. Unlike other E. coli, all the EIEC isolates were non-motile. Both the types of EIEC had multiple plasmids harbouring several virulence encoding genes (ipaBCD, ial, virF, sig, sepA and ipaH). Resistance to recent generation antibiotics were mostly confined to NLF-EIEC but some of the LF-EIEC were resistant only to ceftriaxone. Higher invasion ability and significant increase in the expression of virulence encoding genes by the LF-EIEC (p? Materials and Methods: Recombinant ANG was used to assess its effects on osteoclast formation and bone resorption activity in bone marrow cultures. ANG-knockdown oral squamous carcinoma HSC-2 cells (ANG-RNAi) were transplanted into intramedullary cavities of femurs. Bone destruction was radiologically analyzed, while angiogenesis and osteoclast induction in the surrounding area of the transplanted lesion were histologically examined.
Results: Recombinant ANG promoted osteoclast formation and bone resorption activity. Transplantation of ANG-RNAi cells significantly reduced tumor growth and bone destruction properties compared to transplantation of control cells. Histological analysis revealed lower angiogenesis and fewer osteoclast induction in the ANG-RNAi cells-transplanted group.
Conclusion: ANG mediates oral cancer-induced bone destruction by promoting osteoclast formation and resorption. These findings suggest that ANG could be a potential therapeutic target for suppressing tumor growth, angiogenesis, and bone destruction in oral cancer therapy. en-copyright= kn-copyright= en-aut-name=AOKIKASUMI en-aut-sei=AOKI en-aut-mei=KASUMI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YOSHITANINANA en-aut-sei=YOSHITANI en-aut-mei=NANA kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KURIONAITO en-aut-sei=KURIO en-aut-mei=NAITO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YOSHIOKANORIE en-aut-sei=YOSHIOKA en-aut-mei=NORIE kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TERAMACHIJUMPEI en-aut-sei=TERAMACHI en-aut-mei=JUMPEI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IKEGAMEMIKA en-aut-sei=IKEGAME en-aut-mei=MIKA kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OKAMURAHIROHIKO en-aut-sei=OKAMURA en-aut-mei=HIROHIKO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IBARAGISOICHIRO en-aut-sei=IBARAGI en-aut-mei=SOICHIRO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Oral and Maxillofacial Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Surgery, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Oral Function and Anatomy, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral and Maxillofacial Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Angiogeninoste kn-keyword=Angiogeninoste en-keyword=oclastogenesis kn-keyword=oclastogenesis en-keyword=oral squamous cell carcinoma kn-keyword=oral squamous cell carcinoma en-keyword=osteoclasts kn-keyword=osteoclasts 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=20250612 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Asymptomatic intracranial vascular lesions and cognitive function in a general population of Japanese men: Shiga Epidemiological Study of Subclinical Atherosclerosis (SESSA) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Intracranial subclinical vessel diseases are considered important indicators of cognitive impairment. However, a comprehensive assessment of various types of vessel disease, particularly in Asian populations, is lacking. We aimed to compare multiple types of intracranial vessel disease in association with cognitive function among a community-based Japanese male population. Methods: The Shiga Epidemiological Study of Subclinical Atherosclerosis (SESSA) randomly recruited and examined a community-based cohort of Japanese men from Shiga, Japan. We analyzed those who underwent the Cognitive Abilities Screening Instrument (CASI) assessment and cranial magnetic resonance imaging/angiogram (MRI/MRA) in 2010?2015. Using MRI/MRA, we assessed lacunar infarction, microbleeds, periventricular hyperintensity (PVH), deep subcortical white matter hyperintensity (DSWMH), and intracranial artery stenosis (ICAS). We divided these subclinical cerebrovascular diseases (SCDs) into three categories according to severity. Using linear regression, we calculated the CASI score according to the grade of each vessel disease, adjusted for age and years of education. Results: In the adjusted models, CASI scores were significantly associated with both PVH and DSWMH. Specifically, multivariable-adjusted CASI scores declined across increasing severity categories of DSWMH (91.7, 91.2, and 90.4; p for trend = 0.011) and PVH (91.5, 90.4, and 89.7; p for trend = 0.006). Other SCDs did not show significant associations. In stratified analyses based on the presence or absence of each SCD, both DSWMH and PVH demonstrated significant inverse trends with CASI scores in the absence of lacunar infarcts and microbleeds and in the presence of ICAS. Additionally, among participants with PVH (+), ?moderate ICAS was significantly associated with lower CASI scores. Conclusion: PVH and DSWMH showed significant dose-response relationships with cognitive function among community-based Japanese men. These findings suggest that white matter lesions may be an important indicator of early cognitive impairment, and severe ICAS may also play a role in those with PVH. en-copyright= kn-copyright= en-aut-name=ItoTakahiro en-aut-sei=Ito en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiyoshiAkira en-aut-sei=Fujiyoshi en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhkuboTakayoshi en-aut-sei=Ohkubo en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShiinoAkihiko en-aut-sei=Shiino en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShitaraSatoshi en-aut-sei=Shitara en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyagawaNaoko en-aut-sei=Miyagawa en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ToriiSayuki en-aut-sei=Torii en-aut-mei=Sayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HisamatsuTakashi en-aut-sei=Hisamatsu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SegawaHiroyoshi en-aut-sei=Segawa en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KondoKeiko en-aut-sei=Kondo en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KadotaAya en-aut-sei=Kadota en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TooyamaIkuo en-aut-sei=Tooyama en-aut-mei=Ikuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=WatanabeYoshiyuki en-aut-sei=Watanabe en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=YoshidaKazumichi en-aut-sei=Yoshida en-aut-mei=Kazumichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=NozakiKazuhiko en-aut-sei=Nozaki en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=MiuraKatsuyuki en-aut-sei=Miura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=The SESSA Research Group en-aut-sei=The SESSA Research Group en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= affil-num=1 en-affil=Department of Radiology, Shiga University of Medical Science kn-affil= affil-num=2 en-affil=Department of Radiology, Shiga University of Medical Science kn-affil= affil-num=3 en-affil=Department of Hygiene and Public Health, Teikyo University School of Medicine kn-affil= affil-num=4 en-affil=Molecular Neuroscience Research Center, Shiga University of Medical Science kn-affil= affil-num=5 en-affil=Department of Neurosurgery, Shiga University of Medical Science kn-affil= affil-num=6 en-affil=Department of Preventive Medicine and Public Health, Keio University School of Medicine kn-affil= affil-num=7 en-affil=Department of Radiology, Shiga University of Medical Science kn-affil= affil-num=8 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Radiology, Shiga University of Medical Science kn-affil= affil-num=10 en-affil=Department of Radiology, Shiga University of Medical Science kn-affil= affil-num=11 en-affil=Department of Radiology, Shiga University of Medical Science kn-affil= affil-num=12 en-affil=Molecular Neuroscience Research Center, Shiga University of Medical Science kn-affil= affil-num=13 en-affil=Department of Radiology, Shiga University of Medical Science kn-affil= affil-num=14 en-affil=Department of Neurosurgery, Shiga University of Medical Science kn-affil= affil-num=15 en-affil=Department of Neurosurgery, Shiga University of Medical Science kn-affil= affil-num=16 en-affil=Department of Radiology, Shiga University of Medical Science kn-affil= affil-num=17 en-affil= kn-affil= en-keyword=Cognitive impairment kn-keyword=Cognitive impairment en-keyword=Cerebrovascular disease kn-keyword=Cerebrovascular disease en-keyword=Brain magnetic resonance imaging kn-keyword=Brain magnetic resonance imaging en-keyword=White matter lesion kn-keyword=White matter lesion en-keyword=Community-based population study kn-keyword=Community-based population study END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=roaf042 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Recommendations for the treatment of juvenile idiopathic arthritis with oligoarthritis or polyarthritis from the 2024 update of the Japan College of Rheumatology Clinical Practice Guidelines for the management of rheumatoid arthritis including juvenile idiopathic arthritis with oligoarthritis or polyarthritis ? secondary publication en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: To conduct systematic reviews (SRs) and develop clinical practice guidelines (CPGs) for managing juvenile idiopathic arthritis (JIA) with oligoarthritis or polyarthritis.
Methods: The Grading of Recommendations, Assessment, Development, and Evaluation methodology was employed to carry out SRs and formulate the CPGs. An expert panel, including patients, paediatric and nonpaediatric rheumatologists, guideline specialists, and patient representatives, used the Delphi method to discuss and agree on the recommendations.
Results: Six clinical questions (CQs) on the efficacy and safety of medical treatments were evaluated. These included CQ1 on methotrexate (MTX), CQ2 on non-MTX conventional synthetic disease-modifying antirheumatic drugs, CQ3 on glucocorticoids, CQ4 on tumour necrosis factor inhibitors, CQ5 on interleukin-6 inhibitors, and CQ6 on Janus kinase inhibitors. Two randomized controlled trials were identified for CQ1, three for CQ2, two for CQ3, eight for CQ4, two for CQ5, and two for CQ6. Based on these evaluations, three strong and three conditional recommendations were established. The CPGs have been endorsed by the Japan College of Rheumatology and the Pediatric Rheumatology Association of Japan.
Conclusions: The SRs provided the necessary evidence to develop the CPGs, which are intended to guide not only paediatric but also nonpaediatric rheumatologists, caregivers, patients, and their

Self-Expression, and Early Intervention en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study explored whether metaverse-based support groups could address social isolation and suicide risks among LGBTQ+ youths by providing enhanced anonymity, avatar-based self-expression, and improved accessibility. Over one year, 53 individuals aged 14?23 participated in regular online sessions facilitated via the "cluster" metaverse platform by a non-profit LGBTQ+ organization. Each 90-minute session included voice and text-based interactions within a specially designed single-floor virtual space featuring conversation areas and a designated "safe area" for emotional regulation. Post-session questionnaires (5-point Likert scales) captured demographics, avatar preferences, self-confidence, and perceived safety, self-expression, and accessibility; responses were analyzed with Pearson's chi-squared test and Mann?Whitney U tests (α=0.05). Results indicated that 79.2% of participants selected avatars aligned with their gender identity, reporting high satisfaction (mean = 4.10/5) and minimal discomfort (mean = 1.79/5). Social confidence was significantly higher in the metaverse compared with real-world settings (p<0.001), particularly among those with lower real-world confidence, who exhibited an average gain of 2.08 points. Approximately half of all first-time participants were aged 16 years or younger, which suggested the platform’s value for early intervention. Additionally, the metaverse environment was rated significantly higher in safety/privacy (3.94/5), self-expression (4.02/5), and accessibility (4.21/5) compared with the real-world baseline, and 73.6% reported they felt more accepted virtually. However, some participants who had high confidence offline experienced mild adaptation challenges (mean decrease of 0.58 points), which highlighted that metaverse-based support may be more effective as a complement to in-person services rather than a replacement. Overall, these findings demonstrate that metaverse-based support groups can reduce psychological barriers for LGBTQ+ youth by facilitating safe and affirming virtual environments. The metaverse may help alleviate emotional distress and prevent further severe outcomes, such as suicidal ideation by providing early intervention, especially for adolescents unable to access conventional in-person services. Further research should examine its integration with existing clinical, community, and educational resources to ensure comprehensive, long-term support. en-copyright= kn-copyright= en-aut-name=HaseiJoe en-aut-sei=Hasei en-aut-mei=Joe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoYosuke en-aut-sei=Matsumoto en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawaiHiroki en-aut-sei=Kawai en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkahisaYuko en-aut-sei=Okahisa en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakakiManabu en-aut-sei=Takaki en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Science of Functional Recovery and Reconstruction, Graduate School of Medicine, Dentistry and Pharmaceu-tical Sciences, Okayama University kn-affil= en-keyword=LGBTQ+ Youth kn-keyword=LGBTQ+ Youth en-keyword=Social Isolation kn-keyword=Social Isolation en-keyword=Suicide Prevention kn-keyword=Suicide Prevention en-keyword=Avatar-Based Interventions kn-keyword=Avatar-Based Interventions END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=1 article-no= start-page=cr.25-0141 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=Obese Patient with Gastric Diverticulum Undergoing Laparoscopic Sleeve Gastrectomy Guided by Preoperative Endoscopic Measurement: A Case Report and Literature Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=INTRODUCTION: Gastric diverticulum is a rare condition, often asymptomatic and incidentally detected. Laparoscopic sleeve gastrectomy (LSG) is a widely performed bariatric procedure, but a gastric diverticulum complicates surgical planning. In this case, careful preoperative assessment allowed safe execution of LSG despite the diverticulum’s proximity to the esophagogastric junction.
CASE PRESENTATION: A 45-year-old woman (BMI: 46.8 kg/m2) with hypertension, dyslipidemia, and glucose intolerance was referred for bariatric surgery after unsuccessful weight loss with conservative management. Preoperative endoscopy revealed an 18 × 14 mm gastric diverticulum on the posterior wall of the gastric fundus, 40 mm from the esophagogastric junction. LSG was performed using a surgical stapler, ensuring complete diverticulum resection while preserving gastric tube integrity. The surgery was uneventful, with minimal blood loss and a duration of 2 hours and 52 minutes. The patient had an uneventful postoperative course and was discharged on day 9. Her BMI decreased to 39.3 kg/m2 at the 1-year follow-up, with improved metabolic parameters.
CONCLUSIONS: This case highlights the importance of thorough preoperative evaluation when performing LSG in patients with gastric diverticulum. Accurate endoscopic measurement of the diverticulum’s location aids in determining the optimal resection line, ensuring surgical safety and efficacy. Surgeons should remain vigilant when encountering such anatomical variations to optimize outcomes in bariatric surgery. en-copyright= kn-copyright= en-aut-name=HirosunaKensuke en-aut-sei=Hirosuna en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KashimaHajime en-aut-sei=Kashima en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShojiRyohei en-aut-sei=Shoji en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumiYuki en-aut-sei=Matsumi en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=KikuchiSatoru en-aut-sei=Kikuchi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KurodaShinji en-aut-sei=Kuroda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TeraishiFuminori en-aut-sei=Teraishi en-aut-mei=Fuminori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KagawaShunsuke en-aut-sei=Kagawa en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Center for Graduate Medical Education, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=obese patient kn-keyword=obese patient en-keyword=gastric diverticulum kn-keyword=gastric diverticulum en-keyword=sleeve gastrectomy kn-keyword=sleeve gastrectomy en-keyword=metabolic surgery kn-keyword=metabolic surgery en-keyword=bariatric surgery kn-keyword=bariatric surgery en-keyword=endoscopic measurement kn-keyword=endoscopic measurement END start-ver=1.4 cd-journal=joma no-vol=410 cd-vols= no-issue=1 article-no= start-page=20 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An effective surgical educational system in the era of robotic surgery: “Double-Surgeon Technique” in robotic gastrectomy for minimally invasive surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Gastric cancer (GC) remains a major malignancy. Robotic gastrectomy (RG) has gained popularity due to various advantages. Despite those advantages, many hospitals lack the necessary equipment for RG and are still performing laparoscopic gastrectomy (LG) due to its established minimal invasiveness and safety.
Methods This study assessed the effectiveness of the “Double-Surgeon Technique” (DST) for improving surgical education and proficiency with LG. The DST involves both a console-side surgeon and a patient-side surgeon working actively in RG, enhancing the skill acquisition needed for LG and potentially reducing surgical time. Assessment of this method was performed by surgical time, and cases were divided into three groups: first half (Phase 1: P1) and second half (P2) before the introduction of DST, and after the introduction of DST (P3).
Results Two surgical trainees were trained using the DST. The learning curve in both reached a plateau in P2, but descended again in P3. For one trainee, surgical time for P3 was significantly reduced compared to P1 (p?=?0.001) and P2 (p?=?0.0027) despite the intervals between laparoscopic distal gastrectomy as the main surgeon in P3 being significantly longer than in P2 (p?=?0.0094). Other surgical results in both trainees did not differ significantly. Further, no difference in induction phase results of RG were evident between surgeons and trainees with or without DST experience.
Conclusion Surgical education using the DST could be effective in the current context of the need for RG and LG. en-copyright= kn-copyright= en-aut-name=KakiuchiYoshihiko en-aut-sei=Kakiuchi

　二分脊椎症には、下肢の運動障害と感覚障害、排泄障害に加え、水頭症をはじめとした様々な合併症があることから、運動面、生活面、認知面において適切な支援を要する。さらに、思春期以降になると、脊髄係留による疼痛の出現や、歩行能力の低下に注意する必要がある。神経因性膀胱による排尿障害を合併する場合は、清潔間欠導尿を行う。学校生活を楽しいと肯定的に捉えていた子どもたちのほとんどは、清潔間欠導尿を介助無しあるいは一部の介助のみで排尿することができていた。このことから、担任は、身体的、認知的な支援と配慮に加え、多職種と密な連携を取りながら清潔間欠自己導尿を目指した自立活動の指導を進めることと、良好な友人関係を築くための支援を行うことが重要と思われた。 en-copyright= kn-copyright= en-aut-name=OHMORI (KAWASAKI)Iori en-aut-sei=OHMORI (KAWASAKI) en-aut-mei=Iori kn-aut-name=大守（川ｱ）伊織 kn-aut-sei=大守（川ｱ） kn-aut-mei=伊織 aut-affil-num=1 ORCID= en-aut-name=YAMANAKAMitsuko en-aut-sei=YAMANAKA en-aut-mei=Mitsuko kn-aut-name=山中美津子 kn-aut-sei=山中 kn-aut-mei=美津子 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=Okayama prefectural Okayama east special needs school kn-affil=岡山県立岡山東支援学校 en-keyword=二分脊椎症 kn-keyword=二分脊椎症 en-keyword=清潔間欠導尿 kn-keyword=清潔間欠導尿 en-keyword=学校生活 kn-keyword=学校生活 en-keyword=多職種連携 kn-keyword=多職種連携 END start-ver=1.4 cd-journal=joma no-vol=189 cd-vols= no-issue= article-no= start-page=57 end-page=66 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250822 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=We Discuss What Kind of Sex Education Is Appropriate to End Sexual Violence kn-title=性暴力を根絶するための性教育を問う en-subtitle= kn-subtitle= en-abstract= kn-abstract=　性暴力は、被害者の心身の健康状態に長年にわたって重大な悪影響を及ぼすことが知られている。本研究の目的は、日本における性暴力の実態を文献・資料によって調査し、性暴力を根絶するために求められる性教育を提議することである。内閣府が実施したアンケート調査によると、言葉による性暴力被害は17.8％ 、同意のない性交等の被害は4.1％と報告されていた。被害を受けた場所は学校（ 22.5%）が最多であり、加害者との関係は、「通っていた（いる）学校・大学の関係者（教職員、先輩、同級生、クラブ活動の指導者など）」（ 36.0%）が最も多く、被害者の半数以上は誰にも相談していなかった。これらのデータは、学校においてこそ、性暴力を根絶するための性教育を実施すべきであることを物語っている。しかしながら、学習指導要領に「性的同意」に関する指導は含まれておらず、教科書の記述も極めて限定的であった。性暴力のない社会を実現するためには、幼少期から絵本等を用いた教育やロールプレイを通じた実践的学習が望まれる。 en-copyright= kn-copyright= en-aut-name=OHMORI (KAWASAKI)Iori en-aut-sei=OHMORI (KAWASAKI) en-aut-mei=Iori kn-aut-name=大守（川ｱ） 伊織 kn-aut-sei=大守（川ｱ） kn-aut-mei=伊織 aut-affil-num=1 ORCID= en-aut-name=KOMATSUAyano en-aut-sei=KOMATSU en-aut-mei=Ayano kn-aut-name=小松彩乃 kn-aut-sei=小松 kn-aut-mei=彩乃 aut-affil-num=2 ORCID= en-aut-name=TAKADAChihiro en-aut-sei=TAKADA en-aut-mei=Chihiro kn-aut-name=田千尋 kn-aut-sei=田 kn-aut-mei=千尋 aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Education，Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=2 en-affil=Faculty of Education，Okayama University kn-affil=岡山大学教育学部 affil-num=3 en-affil=Faculty of Education，Okayama University kn-affil=岡山大学教育学部 en-keyword=性教育 kn-keyword=性教育 en-keyword=性暴力 kn-keyword=性暴力 en-keyword=レイプ kn-keyword=レイプ en-keyword=性的同意 kn-keyword=性的同意 END start-ver=1.4 cd-journal=joma no-vol=189 cd-vols= no-issue= article-no= start-page=37 end-page=56 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250822 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Perspectives on Virtual Team Research: Paradoxes Facing Team Management in the DX Era kn-title=バーチャルチーム研究のパースペクティブ ― DX 時代のチームマネジメントが直面するパラドックス ― en-subtitle= kn-subtitle= en-abstract= kn-abstract=　情報通信技術の発展や新型コロナウイルス感染症の感染拡大を契機として，組織におけるバーチャルチーム（virtual team;

Recently, changes in the physical property of Hsf1 condensates due to persistent stress have been suggested to trigger apoptosis, highlighting the importance of biological phase separation and transition in cell fate decisions. In this study, the mechanism underlying Hsf1 droplet formation and oxidative response was investigated through 3D refractive index imaging of the internal architecture, corroborated by molecular dynamics simulations and biophysical/biochemical experiments. We found that, in response to oxidative conditions, Hsf1 formed liquid condensates that suppressed its internal mobility. Furthermore, these conditions triggered the hyper-oligomerization of Hsf1, mediated by disulfide bonds and secondary structure stabilization, leading to the formation of dense core particles in the Hsf1 droplet. Collectively, these data demonstrate how the physical property of Hsf1 condensates undergoes an oxidative transition by sensing redox conditions to potentially drive cell fate decisions. en-copyright= kn-copyright= en-aut-name=KawagoeSoichiro en-aut-sei=Kawagoe en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsusakiMotonori en-aut-sei=Matsusaki en-aut-mei=Motonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MabuchiTakuya en-aut-sei=Mabuchi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OgasawaraYuto en-aut-sei=Ogasawara en-aut-mei=Yuto 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=IshimoriKoichiro en-aut-sei=Ishimori en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaioTomohide en-aut-sei=Saio en-aut-mei=Tomohide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Institute of Advanced Medical Sciences, Tokushima University kn-affil= affil-num=2 en-affil=Institute of Advanced Medical Sciences, Tokushima University kn-affil= affil-num=3 en-affil=Frontier Research Institute for Interdisciplinary Sciences, Tohoku 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 Chemistry, Faculty of Science, Hokkaido University kn-affil= affil-num=7 en-affil=Institute of Advanced Medical Sciences, Tokushima University kn-affil= en-keyword=heat shock factor 1 kn-keyword=heat shock factor 1 en-keyword=oxidative hyper-oligomerization kn-keyword=oxidative hyper-oligomerization en-keyword=biological phase transition kn-keyword=biological phase transition en-keyword=stress response kn-keyword=stress response en-keyword=biophysics kn-keyword=biophysics END start-ver=1.4 cd-journal=joma no-vol=472 cd-vols= no-issue= article-no= start-page=123486 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical, neuroimaging and genetic findings in the Japanese case series of CLCN2-related leukoencephalopathy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Biallelic loss-of-function variants in CLCN2 lead to CLCN2-related leukoencephalopathy (CC2L), also called leukoencephalopathy with ataxia (LKPAT). CC2L is characterized clinically by a spectrum of clinical presentations including childhood- to adult-onset mild ataxia, spasticity, cognitive decline, and vision loss as well as typical MRI findings of symmetrical high signal intensities on the DWIs/T2WIs of the middle cerebellar peduncles (MCPs). We searched for pathogenic variants of CLCN2 in a case series of undiagnosed leukoencephalopathy accompanied by MCP signs, which led to the identification of four Japanese patients with CC2L. All the patients carried at least one allele of c.61dupC (p.Leu21Profs*27) in CLCN2, including compound heterozygosity with either the novel pathogenic variant c.983 + 2 T > A or the previously reported pathogenic variant c.1828C > T (p.Arg610*). Of note, all the four previously reported cases from Japan also harbored c.61dupC, and no reports of this variant have been documented from outside Japan. The allele frequency of c.61dupC in the Japanese population is 0.002152, raising the possibility of a relatively high prevalence of CC2L in Japan. Patients in this study developed symptoms after the age of 30, and demonstrated neurological signs including cerebellar ataxia, pyramidal signs, and mild cognitive impairment, consistent with previous reports. One male patient had two children, supporting preserved fertility, and another patient had calcifications in the cerebral and cerebellar surfaces. These findings provide valuable insights into the broader clinical and genetic spectra of CC2L in the Japanese population, and emphasize the importance of considering this disease in the differential diagnoses of leukoencephalopathy with MCP signs. en-copyright= kn-copyright= en-aut-name=OrimoKenta en-aut-sei=Orimo en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

Protecting Intestinal Barrier and Inhibiting Inflammasome-Associated Activation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Nonsteroidal anti-inflammatory drugs (NSAID), which are commonly used to manage pain and inflammation, often cause gastrointestinal injuries, including small intestinal damage. Berberine (BBR) is a traditional Chinese medicine that protects against these injuries. However, the mechanism of action is not fully understood.
Aims This study aimed to evaluate the protective effects of BBR against NSAID-induced intestinal injury and elucidate the underlying molecular mechanisms.
Methods We evaluated the effects of BBR on NSAID-induced intestinal injury using a combination of mouse models and human gut organoids. Mice were treated with indomethacin with or without BBR to induce small intestinal injury. Human gut organoids were exposed to NSAID, with or without BBR, to assess their direct epithelial effects. Histological analyses, cytokine measurements, and Western blotting were performed to evaluate intestinal damage, tight junction integrity, and inflammasome-associated activation.
Results In NSAID-treated mice, BBR markedly reduced ulcers and adhesions and preserved ileal Claudin-1, Occludin, and Zonula Occludens-1 (ZO-1) levels. BBR inhibited both NOD-like receptor family pyrin domain-containing 6 and NOD-like receptor family caspase recruitment domain?containing protein 4 inflammasome activation, reducing Caspase-1 maturation and downstream interleukin-1β and tumor necrosis factor-α release. In human gut organoids, BBR demonstrated comparable protective effects by directly mitigating NSAID-induced epithelial barrier disruption caused by Claudin-1 and Occludin downregulation, although it did not restore ZO-1 expression.
Conclusions BBR effectively prevented NSAID-induced small intestinal injury by maintaining tight junction integrity and inhibiting inflammasome-associated activation, indicating its potential as a therapeutic agent against such damage. en-copyright= kn-copyright= en-aut-name=IshiguroMikako en-aut-sei=Ishiguro en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakaharaMasahiro en-aut-sei=Takahara en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakakiAkinobu en-aut-sei=Takaki en-aut-mei=Akinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ToyosawaJyunki en-aut-sei=Toyosawa en-aut-mei=Jyunki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AoyamaYuki en-aut-sei=Aoyama en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IgawaShoko en-aut-sei=Igawa en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamasakiYasushi en-aut-sei=Yamasaki en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=InokuchiToshihiro en-aut-sei=Inokuchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KinugasaHideaki en-aut-sei=Kinugasa en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Nonsteroidal anti-inflammatory drugs-induced small intestinal injury kn-keyword=Nonsteroidal anti-inflammatory drugs-induced small intestinal injury en-keyword=Berberine kn-keyword=Berberine en-keyword=Tight junction protein kn-keyword=Tight junction protein en-keyword=Inflammasomes kn-keyword=Inflammasomes END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=4 article-no= start-page=231 end-page=242 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=Bloodstream Infections Caused by Gram-Negative Bacteria in Geriatric Patients: Epidemiology, Antimicrobial Resistance and The Factors Affecting Mortality en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bloodstream infections (BSIs) are an important cause of morbidity and mortality in geriatric patients. We retrospectively analyzed the cases of geriatric patients who developed BSIs due to gram-negative bacteria in order to evaluate the epidemiology, antimicrobial resistance, and the factors affecting mortality. The cases of 110 patients aged ? 65 years admitted to our hospital between January 1, 2017, and December 31, 2022 were assessed; 70 (63.6%) of the BSIs were healthcare-associated BSIs. The urinary system was the most common detectable source of infection at 43.6%. The most frequently isolated bacteria were Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae, in that order. Carbapenem resistance was detected in 17 patients (15.5%), and extended-spectrum beta-lactamase (ESBL) production from Enterobacterales family members was detected in 37 (51.4%) patients. Multivariate analysis revealed that (i) the probability of mortality in the patients with total bilirubin was increased by approx. sixfold and (ii) the likelihood of mortality for those with a Pitt bacteremia score (PBS) ? 4 points was approx. 17 times higher. PBS and simplified qPitt scores can help predict mortality and manage geriatric patients. There is a significant increase in mortality among patients with procalcitonin (PCT) levels at ? 2 nm/ml. en-copyright= kn-copyright= en-aut-name=KardanM Enes en-aut-sei=Kardan en-aut-mei=M Enes kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ErdemIlknur en-aut-sei=Erdem en-aut-mei=Ilknur kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YildizEmre en-aut-sei=Yildiz en-aut-mei=Emre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KirazNuri en-aut-sei=Kiraz en-aut-mei=Nuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=?elikkolAliye en-aut-sei=?elikkol en-aut-mei=Aliye kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Infectious Diseases, Faculty of Medicine, Namik Kemal University kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Faculty of Medicine, Namik Kemal University kn-affil= affil-num=3 en-affil=Department of Infectious Diseases, Faculty of Medicine, Namik Kemal University kn-affil= affil-num=4 en-affil=Department of Medical Microbiology, Faculty of Medicine, Namik Kemal University kn-affil= affil-num=5 en-affil=Department of Biochemistry, Faculty of Medicine, Namik Kemal University kn-affil= en-keyword=geriatrics kn-keyword=geriatrics en-keyword=gram-negative bacteria kn-keyword=gram-negative bacteria en-keyword=epidemiology kn-keyword=epidemiology en-keyword=antimicrobial resistance kn-keyword=antimicrobial resistance en-keyword=mortality kn-keyword=mortality END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=4 article-no= start-page=221 end-page=229 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=Organ Donation after Extracorporeal Cardiopulmonary Resuscitation: Clinical and Ethical Perspectives en-subtitle= kn-subtitle= en-abstract= kn-abstract=Extracorporeal cardiopulmonary resuscitation (ECPR) has evolved into a life-saving therapy for select cardiac arrest patients, yet a growing body of evidence suggests it also holds promise as a bridge to organ donation in non-survivors. This review explores the clinical outcomes, ethical complexities, and evolving policies surrounding organ donation after ECPR. We summarize recent international and Japanese data demonstrating favorable graft function from ECPR donors, with the exception of lung transplantation. The ethical challenges ? particularly those involving brain death determination on extracorporeal membrane oxygenation and adherence to the dead donor rule ? are discussed in the context of Japan’s recent regulatory reforms. Additionally, we highlight the importance of structured end-of-life communication through multidisciplinary team meetings in facilitating ethically sound transitions from rescue efforts to donation pathways. Moving forward, improvements in donor management, standardized legal frameworks, and public and professional education are essential to optimizing the life-saving and life-giving potential of ECPR. 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=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 ORCID= en-aut-name=AgetaKohei en-aut-sei=Ageta en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=brain death kn-keyword=brain death en-keyword=end-of-life care kn-keyword=end-of-life care en-keyword=ethical dilemmas kn-keyword=ethical dilemmas en-keyword=extracorporeal cardiopulmonary resuscitation kn-keyword=extracorporeal cardiopulmonary resuscitation 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=20250613 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Distinct age-related effects of homologous recombination deficiency on genomic profiling and treatment efficacy in gastric cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background The incidence of gastric cancer among younger patients is increasing globally, with growing attention being paid to the role of homologous recombination deficiency (HRD). However, the effect of HRD on treatment outcomes and prognosis in this population remains unclear.
Methods We analyzed clinical and genomic data from the Center for Cancer Genomics and Advanced Therapeutics database. Younger patients (??39 years, n?=?140) were compared with older patients (??65 years, n?=?1118) diagnosed with gastric cancer. This study focused on mutations in homologous recombination repair (HRR) genes and their association with tumor mutation burden (TMB), microsatellite instability (MSI), and treatment outcomes.
Results In older patients, HRD was associated with higher TMB and microsatellite instability-high (MSI-H) status, whereas no such correlations were observed in younger patients. Notably, MSI-H status was not observed in the younger group. Younger patients with HRD had a significantly shorter time to treatment failure (TTF) and overall survival (OS) than those without HRD. Conversely, in older patients, there was no significant difference in TTF or OS based on HRD status.
Conclusion HRR gene mutations influence genomic profiling, TMB, and MSI differently depending on the age of gastric cancer onset, suggesting potential effects on treatment efficacy and prognosis. en-copyright= kn-copyright= en-aut-name=MakiYoshie en-aut-sei=Maki en-aut-mei=Yoshie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KonoYoshiyasu en-aut-sei=Kono en-aut-mei=Yoshiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OzatoToshiki en-aut-sei=Ozato en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoHideki en-aut-sei=Yamamoto en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HirasawaAkira en-aut-sei=Hirasawa en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TomidaShuta en-aut-sei=Tomida en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=HamadaKenta en-aut-sei=Hamada en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= affil-num=1 en-affil=Faculty of Medicine, Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Medicine, Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Medicine, Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Clinical Genomic Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Clinical Genomic Medicine, Okayama University Hospital kn-affil= affil-num=6 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Faculty of Medicine, Department of Practical Gastrointestinal Endoscopy, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Faculty of Medicine, Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Faculty of Medicine, Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Homologous recombination repair gene kn-keyword=Homologous recombination repair gene en-keyword=Early-onset gastric cancer kn-keyword=Early-onset gastric cancer en-keyword=Comprehensive genomic profiling kn-keyword=Comprehensive genomic profiling END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=5 article-no= start-page=271 end-page=277 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240329 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Japan MSA registry: A multicenter cohort study of multiple system atrophy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Multiple system atrophy (MSA) is a neurodegenerative disorder characterized by autonomic failure and various motor symptoms. While MSA-C (cerebellar type) predominates in East Asia, MSA-P (parkinsonian type) predominates in Europe and North America. This nationwide patient registry aimed to (1) conduct a prospective natural history study of MSA in Japan, (2) facilitate patient recruitment for clinical trials, and (3) deposit bioresources and clinical information in a biobank.
Methods: Thirteen institutions participated in this study. Clinical information was obtained by neurologists from the patients visiting the hospital every 12?months to assess the UMSARS Part 2 scores and by telephone interviews by nurses every 6?months to assess UMSARS Part 1 scores and to determine whether clinical events had occurred.
Results: Demographic data from 329 MSA patients (216 MSA-C and 113 MSA-P) were analyzed. The mean age at symptom onset was 58.2?years (standard deviation, 8.9); the mean duration of symptoms at enrollment was 3.5?years (standard deviation, 2.2). The mean 12-month changes in the UMSARS Part 1 and Part 2 scores were 7.9 (standard deviation, 5.6) and 6.4 (standard deviation, 5.9), respectively. The patient registry proved useful in recruiting participants for clinical trials, including those with gene variants. Clinical information and biospecimens were deposited in a biobank.
Discussion: The study highlighted the importance of telephone interviews in minimizing drop-out rates in natural history studies and demonstrated similar MSA progression rates across populations. The deposited bioresources are available to researchers upon request, aiming to contribute to future MSA researches. en-copyright= kn-copyright= en-aut-name=ChikadaAyaka en-aut-sei=Chikada

en-subtitle= kn-subtitle= en-abstract= kn-abstract=We previously reported that live, but not dead, virulent Mycobacterium tuberculosis (Mtb) H37Rv bacilli induce cell death in human lung fibroblast cell lines, MRC-5, MRC-9, and TIG-1. Here, using two distinct Mtb strains from two different lineages (HN878 lineage 2 and H37Rv lineage 4), we confirmed cell death at day 2 after infection with a device that measures cell growth/cytotoxicity in real time (Maestro-Z [AXION]). Mtb bacilli uptake by the fibroblast was confirmed with a transmission electron microscope on day 2. Expressions of inflammatory cytokines and interleukin (IL)?1β, IL-6, and IL-8 were observed when exposed to live, but not dead bacteria. The cell death of fibroblasts induced by both Mtb strains tested was prevented by caspase-1/4 and NLRP3 inflammasome inhibitors, but not by caspase-3 and caspase-9 inhibitors. Therefore, we classified the fibroblast cell death by Mtb infection as pyroptosis. To investigate the biological and pathological relevance of fibroblast cell death by Mtb infection, we performed dual RNA-Seq analysis on Mtb within fibroblasts and Mtb-infected fibroblasts at day 2. In Mtb bacilli tcrR, secE2, ahpD, and mazF8 genes were highly induced during infection. These genes play roles in survival in a hypoxic environment, production of a calcium-binding protein-inducing cytokine, and regulation of transcription in a toxin-antitoxin system. The gene expressions of IL-1β, IL-6, and IL-8, caspase-4, and NLRP3, but not of caspase-3 and caspase-9, were augmented in Mtb bacilli-infected fibroblasts. Taken together, our study suggests that Mtb bacilli attempt to survive in lung fibroblasts and that pyroptosis of the host fibroblasts activates the immune system against the infection. en-copyright= kn-copyright= en-aut-name=TakiiTakemasa en-aut-sei=Takii en-aut-mei=Takemasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamadaHiroyuki en-aut-sei=Yamada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MotozonoChihiro en-aut-sei=Motozono en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamasakiSho en-aut-sei=Yamasaki en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TorrellesJordi B. en-aut-sei=Torrelles en-aut-mei=Jordi B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TurnerJoanne en-aut-sei=Turner en-aut-mei=Joanne kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KimishimaAoi en-aut-sei=Kimishima en-aut-mei=Aoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AsamiYukihiro en-aut-sei=Asami en-aut-mei=Yukihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=HidaShigeaki en-aut-sei=Hida en-aut-mei=Shigeaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HayashiHidetoshi en-aut-sei=Hayashi en-aut-mei=Hidetoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OnozakiKikuo en-aut-sei=Onozaki en-aut-mei=Kikuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Mycobacterium Reference and Research, the Research Institute of Tuberculosis, Japan Anti-Tuberculosis Association kn-affil= affil-num=2 en-affil=Department of Mycobacterium Reference and Research, the Research Institute of Tuberculosis, Japan Anti-Tuberculosis Association kn-affil= affil-num=3 en-affil=Department of Molecular Immunology, Research Institute for Microbial Diseases, The University of Osaka kn-affil= affil-num=4 en-affil=Department of Molecular Immunology, Research Institute for Microbial Diseases, The University of Osaka kn-affil= affil-num=5 en-affil=Texas Biomedical Research Institute and International Center for the Advancement of Research & Education (I?CARE) kn-affil= affil-num=6 en-affil=Texas Biomedical Research Institute and International Center for the Advancement of Research & Education (I?CARE) kn-affil= affil-num=7 en-affil=Laboratory of Applied Microbial Chemistry, ?mura Satoshi Memorial Institute, Kitasato University kn-affil= affil-num=8 en-affil=Laboratory of Applied Microbial Chemistry, ?mura Satoshi Memorial Institute, Kitasato University kn-affil= affil-num=9 en-affil=Department of Oral Microbiology, Graduate School of Medicine, Density and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Hygienic Chemistry, Graduate School of Pharmaceutical Sciences, Nagoya City University kn-affil= affil-num=11 en-affil=Department of Cell Signaling, Graduate School of Pharmaceutical Sciences, Nagoya City University kn-affil= affil-num=12 en-affil=Department of Hygienic Chemistry, Graduate School of Pharmaceutical Sciences, Nagoya City University kn-affil= en-keyword=Mycobacterium tuberculosis kn-keyword=Mycobacterium tuberculosis en-keyword=pyroptosis kn-keyword=pyroptosis en-keyword=caspase kn-keyword=caspase en-keyword=RNA-Seq kn-keyword=RNA-Seq en-keyword=cytokine kn-keyword=cytokine en-keyword=fibroblasts kn-keyword=fibroblasts END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=8 article-no= start-page=522 end-page=532 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240625 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis and biochemical characterization of naphthoquinone derivatives targeting bacterial histidine kinases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Waldiomycin is an inhibitor of histidine kinases (HKs). Although most HK inhibitors target the ATP-binding region, waldiomycin binds to the intracellular dimerization domain (DHp domain) with its naphthoquinone moiety presumed to interact with the conserved H-box region. To further develop inhibitors targeting the H-box, various 2-aminonaphthoquinones with cyclic, aliphatic, or aromatic amino groups and naphtho [2,3-d] isoxazole-4,9-diones were synthesized. These compounds were tested for their inhibitory activity (IC50) against WalK, an essential HK for Bacillus subtilis growth, and their minimum inhibitory concentrations (MIC) against B. subtilis. As a result, 11 novel HK inhibitors were obtained as naphthoquinone derivatives (IC50: 12.6?305??M, MIC: 0.5?128??g?ml?1). The effect of representative compounds on the expression of WalK/WalR regulated genes in B. subtilis was investigated. Four naphthoquinone derivatives induced the expression of iseA (formerly yoeB), whose expression is negatively regulated by the WalK/WalR system. This suggests that these compounds inhibit WalK in B. subtilis cells, resulting in antibacterial activity. Affinity selection/mass spectrometry analysis was performed to identify whether these naphthoquinone derivatives interact with WalK in a manner similar to waldiomycin. Three compounds were found to competitively inhibit the binding of waldiomycin to WalK, suggesting that they bind to the H-box region conserved in HKs and inhibit HK activity. en-copyright= kn-copyright= en-aut-name=IshikawaTeruhiko en-aut-sei=Ishikawa en-aut-mei=Teruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EguchiYoko en-aut-sei=Eguchi en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IgarashiMasayuki en-aut-sei=Igarashi en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkajimaToshihide en-aut-sei=Okajima en-aut-mei=Toshihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MitaKohei en-aut-sei=Mita en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamasakiYuri en-aut-sei=Yamasaki en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SumikuraKaho en-aut-sei=Sumikura en-aut-mei=Kaho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkumuraTaisei en-aut-sei=Okumura en-aut-mei=Taisei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TabuchiYuna en-aut-sei=Tabuchi en-aut-mei=Yuna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HayashiChigusa en-aut-sei=Hayashi en-aut-mei=Chigusa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=PasquaMartina en-aut-sei=Pasqua en-aut-mei=Martina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ColucciaMarco en-aut-sei=Coluccia en-aut-mei=Marco kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=ProssedaGianni en-aut-sei=Prosseda en-aut-mei=Gianni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=ColonnaBianca en-aut-sei=Colonna en-aut-mei=Bianca kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=KohayakawaChie en-aut-sei=Kohayakawa en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=TaniAkiyoshi en-aut-sei=Tani en-aut-mei=Akiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=HarutaJun-ichi en-aut-sei=Haruta en-aut-mei=Jun-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=UtsumiRyutaro en-aut-sei=Utsumi en-aut-mei=Ryutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University kn-affil= affil-num=2 en-affil=Department of Science and Technology on Food Safety, Faculty of Biology-Oriented Science and Technology, Kindai University kn-affil= affil-num=3 en-affil=Institute of Microbial Chemistry (BIKAKEN) kn-affil= affil-num=4 en-affil=SANKEN (The Institute of Scientific and Industrial Research), Osaka University kn-affil= affil-num=5 en-affil=Graduate School of Education, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Education, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Education, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Education, Okayama University kn-affil= affil-num=9 en-affil=Graduate School of Education, Okayama University kn-affil= affil-num=10 en-affil=Institute of Microbial Chemistry (BIKAKEN) kn-affil= affil-num=11 en-affil=Istituto Pasteur Italy, Department of Biology and Biotechnology, “C.

This systematic scoping review evaluated the effectiveness, cost-efficiency, and challenges of telemedicine for patients with rheumatic diseases.
Methods: A comprehensive search of the MEDLINE database was conducted using specific terms related to rheumatoid or juvenile arthritis, and telemedicine. The literature search included studies published up to March, 2024. In this review, we only considered studies assessing telemedicine as an alternative to in-person care.
Results: The search, conducted on 15 March 2024, generated 258 references. Eight reports from three randomized controlled trials and three observational studies were included. Randomized controlled trials have shown that the outcomes of telemedicine intervention are comparable to those of in-person care in terms of disease activity, functional status, and quality of life, while enabling fewer outpatient visits and cost-effectiveness. However, the high dropout rates highlight the importance of patient preferences and comprehensive education. Observational studies revealed similar findings but were limited by a high confounding bias.
Conclusion: Telemedicine offers economic advantages and maintains clinical outcomes comparable to those of in-person care. Its success depends on structured patient education and alignment with patient preferences. Further research is required, particularly in the context of healthcare in Japan. en-copyright= kn-copyright= en-aut-name=SadaKen-ei en-aut-sei=Sada en-aut-mei=Ken-ei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwataShigeru en-aut-sei=Iwata en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InoueYuzaburo en-aut-sei=Inoue en-aut-mei=Yuzaburo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaEiichi en-aut-sei=Tanaka en-aut-mei=Eiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishidaKeiichiro en-aut-sei=Nishida en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KawahitoYutaka en-aut-sei=Kawahito en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AbeAsami en-aut-sei=Abe en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawakamiAtsushi en-aut-sei=Kawakami en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MiyamaeTakako en-aut-sei=Miyamae en-aut-mei=Takako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Clinical Epidemiology, Kochi Medical School kn-affil= affil-num=2 en-affil=Department of Rheumatology and Clinical Immunology, Wakayama Medical University kn-affil= affil-num=3 en-affil=Department of General Medical Science, Graduate School of Medicine, Chiba University kn-affil= affil-num=4 en-affil=Department of Rheumatology, Tokyo Women’s Medical University School of Medicine kn-affil= affil-num=5 en-affil=Locomotive Pain Center, Okayama University Hospital kn-affil= affil-num=6 en-affil=Inflammation and Immunology, Graduate School of Medical Science, Kyoto Prefectural University of Medicine kn-affil= affil-num=7 en-affil=Department of Rheumatology, Niigata Rheumatic Center kn-affil= affil-num=8 en-affil=Department of Immunology and Rheumatology, Division of Advanced Preventive Medical Sciences, Nagasaki University Graduate School of Biomedical Sciences kn-affil= affil-num=9 en-affil=Department of Pediatric Rheumatology, Institute of Rheumatology, Tokyo Women’s Medical University kn-affil= en-keyword=Digital health kn-keyword=Digital health en-keyword=telemedicine kn-keyword=telemedicine en-keyword=remote care kn-keyword=remote care en-keyword=rheumatic disease kn-keyword=rheumatic disease en-keyword=scoping review kn-keyword=scoping review END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=12 article-no= start-page=2429 end-page=2437 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Discovery of a Compound That Inhibits IRE1α S-Nitrosylation and Preserves the Endoplasmic Reticulum Stress Response under Nitrosative Stress en-subtitle= kn-subtitle= en-abstract= kn-abstract=Inositol-requiring enzyme 1α (IRE1α) is a sensor of endoplasmic reticulum (ER) stress and drives ER stress response pathways. Activated IRE1α exhibits RNase activity and cleaves mRNA encoding X-box binding protein 1, a transcription factor that induces the expression of genes that maintain ER proteostasis for cell survival. Previously, we showed that IRE1α undergoes S-nitrosylation, a post-translational modification induced by nitric oxide (NO), resulting in reduced RNase activity. Therefore, S-nitrosylation of IRE1α compromises the response to ER stress, making cells more vulnerable. We conducted virtual screening and cell-based validation experiments to identify compounds that inhibit the S-nitrosylation of IRE1α by targeting nitrosylated cysteine residues. We ultimately identified a compound (1ACTA) that selectively inhibits the S-nitrosylation of IRE1α and prevents the NO-induced reduction of RNase activity. Furthermore, 1ACTA reduces the rate of NO-induced cell death. Our research identified S-nitrosylation as a novel target for drug development for IRE1α and provides a suitable screening strategy. en-copyright= kn-copyright= en-aut-name=KurogiHaruna en-aut-sei=Kurogi en-aut-mei=Haruna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakasugiNobumasa en-aut-sei=Takasugi en-aut-mei=Nobumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KubotaSho en-aut-sei=Kubota en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KumarAshutosh en-aut-sei=Kumar en-aut-mei=Ashutosh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SuzukiTakehiro en-aut-sei=Suzuki en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DohmaeNaoshi en-aut-sei=Dohmae en-aut-mei=Naoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SawadaDaisuke en-aut-sei=Sawada en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ZhangKam Y.J. en-aut-sei=Zhang en-aut-mei=Kam Y.J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UeharaTakashi en-aut-sei=Uehara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Laboratory for Structural Bioinformatics, Center for Biosystems Dynamics Research, RIKEN kn-affil= affil-num=5 en-affil=Biomolecular Characterization Unit, Technology Platform Division, RIKEN Center for Sustainable Resource Science kn-affil= affil-num=6 en-affil=Biomolecular Characterization Unit, Technology Platform Division, RIKEN Center for Sustainable Resource Science kn-affil= affil-num=7 en-affil=Department of Fine Organic Synthesis, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Laboratory for Structural Bioinformatics, Center for Biosystems Dynamics Research, RIKEN kn-affil= affil-num=9 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=10 article-no= start-page=1444 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250516 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Canine c-kit Novel Mutation Isolated from a Gastrointestinal Stromal Tumor (GIST) Retains the Ability to Form Dimers but Lacks Autophosphorylation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Gastrointestinal stromal tumors (GISTs) are mesenchymal tumors that develop in the gastrointestinal tract; KIT mutations are present in both canine and human GISTs. In this study, genomic DNA was extracted from formalin-fixed paraffin-embedded (FFPE) sections of 55 canine GIST cases, and mutation searches were performed for exons 8, 9, and 11. The results revealed novel mutations, A434T and F436S, in exon 8. In contrast to the A434T mutation without functional changes, the F436S mutant retained its dimerization ability, but lost its phosphorylation function and attenuated downstream Akt signaling, which is reflected in wound healing and migration activities. A comparison of the subcellular localization of WT KIT and the F436S mutant revealed no differences. In silico simulations indicated that the F436S mutation alters the structure of the near-membrane region and that its effects may extend to the transmembrane and intracellular domains compared to the WT. F436S is a point mutation that affects the entire molecule because co-mutation with the F436S mutation and the known autophosphorylation mutation reduces the autophosphorylation abilities. en-copyright= kn-copyright= en-aut-name=ShimakawaKei en-aut-sei=Shimakawa en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DogeSo en-aut-sei=Doge en-aut-mei=So kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MichishitaMasaki en-aut-sei=Michishita en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanabeEri en-aut-sei=Tanabe en-aut-mei=Eri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TajimaTsuyoshi en-aut-sei=Tajima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KobayashiMasato en-aut-sei=Kobayashi en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=BonkobaraMakoto en-aut-sei=Bonkobara en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeMasami en-aut-sei=Watanabe en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OchiaiKazuhiko en-aut-sei=Ochiai en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaYoshikazu en-aut-sei=Tanaka en-aut-mei=Yoshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Laboratory of Veterinary Hygiene, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=2 en-affil=Laboratory of Veterinary Pathology, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=3 en-affil=Laboratory of Veterinary Pathology, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=4 en-affil=Laboratory of Veterinary Hygiene, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=5 en-affil=Laboratory of Veterinary Pharmacology, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=6 en-affil=Laboratory of Veterinary Reproduction, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=7 en-affil=Laboratory of Veterinary Clinical Pathology, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=8 en-affil=Laboratory of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Laboratory of Veterinary Hygiene, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=10 en-affil=Laboratory of Veterinary Hygiene, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= en-keyword=autophosphorylation kn-keyword=autophosphorylation en-keyword=canine kn-keyword=canine en-keyword=c-kit kn-keyword=c-kit en-keyword=GIST kn-keyword=GIST en-keyword=KIT kn-keyword=KIT en-keyword=loss-of-function mutation kn-keyword=loss-of-function mutation END start-ver=1.4 cd-journal=joma no-vol=52 cd-vols= no-issue=14 article-no= start-page=e2024GL114146 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250718 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Unraveling the Complex Features of the Seismic Scatterers in the Mid‐Lower Mantle Through Phase Transition of (Al, H)‐Bearing Stishovite en-subtitle= kn-subtitle= en-abstract= kn-abstract=Small-scale scatterers observed in the mid-lower mantle beneath the subduction zones are thought to result from the phase transition of stishovite within subducted oceanic crusts. Here we investigate the phase transition of (Al, H)-bearing stishovite with four compositions at simultaneously high P-T conditions combining Raman spectroscopy and X-ray diffraction. These experimental results reveal that the incorporation of 0.01 a.p.f.u Al into stishovite with H/Al ratio of ?1/3 lowers the transition pressure by 6.7(3) GPa. However, the Clapeyron slope of this transition is nearly unaffected by changes in the Al content and has a value of 12.2?12.5(3) MPa/K. According to our results, Al content variation ranging from 0 to 0.07 a.p.f.u in SiO2 can reasonably explain the depth distribution from 800 to 1,900 km of the seismic scatterers observed in the circum-Pacific region. These results deepen our understanding on the complex features of mid-lower mantle seismic scatterers and corresponding dynamic processes. en-copyright= kn-copyright= en-aut-name=YuYingxin en-aut-sei=Yu en-aut-mei=Yingxin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZhangYouyue en-aut-sei=Zhang en-aut-mei=Youyue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LiLuo en-aut-sei=Li en-aut-mei=Luo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZhangXinyue en-aut-sei=Zhang en-aut-mei=Xinyue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WangDenglei en-aut-sei=Wang en-aut-mei=Denglei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MaoZhu en-aut-sei=Mao en-aut-mei=Zhu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SunNingyu en-aut-sei=Sun en-aut-mei=Ningyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ZhangYanyao en-aut-sei=Zhang en-aut-mei=Yanyao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=LiXinyang en-aut-sei=Li en-aut-mei=Xinyang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=LiWancai en-aut-sei=Li en-aut-mei=Wancai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SpezialeSergio en-aut-sei=Speziale en-aut-mei=Sergio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= en-aut-name=LinJung‐Fu en-aut-sei=Lin en-aut-mei=Jung‐Fu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 ORCID= affil-num=1 en-affil=Deep Space Exploration Laboratory, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=2 en-affil=Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=Deep Space Exploration Laboratory, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=4 en-affil=Deep Space Exploration Laboratory, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=5 en-affil=Deep Space Exploration Laboratory, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=6 en-affil=Deep Space Exploration Laboratory, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=7 en-affil=Deep Space Exploration Laboratory, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=8 en-affil=Earth and Planetary Sciences, Stanford University kn-affil= affil-num=9 en-affil=State Key Laboratory of High Pressure and Superhard Materials, College of Physics, Jilin University kn-affil= affil-num=10 en-affil=CAS Key Laboratory of Crust‐Mantle Materials and Environments, School of Earth and Space Sciences, University of Science and Technology of China kn-affil= affil-num=11 en-affil=GFZ German Research Centre for Geosciences kn-affil= affil-num=12 en-affil=GeoSoilEnviroCARS, University of Chicago kn-affil= affil-num=13 en-affil=Department of Earth and Planetary Sciences, Jackson School of Geosciences, The University of Texas at Austin kn-affil= affil-num=14 en-affil=Institute for Planetary Materials, Okayama University kn-affil= en-keyword=(Al, H)-bearing stishovite kn-keyword=(Al, H)-bearing stishovite en-keyword=phase transition kn-keyword=phase transition en-keyword=mid-lower mantle kn-keyword=mid-lower mantle en-keyword=small-scale seismic scatterers kn-keyword=small-scale seismic scatterers END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=1041 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Longitudinal changes and tracking of in-school physical activity in primary school children: four-year longitudinal study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background There is little evidence on the tracking of physical activity during school hours. In addition, tracking physical activity in schools provides important evidence for understanding children’s physical activity and conducting intervention studies. Therefore, this study examined longitudinal changes and tracking of in-school physical activity in primary school children.
Methods In this study, physical activity was investigated longitudinally in primary school children for 4 years. The baseline participants consisted of 103 second-grade students (7?8 years old) who participated. Step counts and moderate-to-vigorous physical activity (MVPA) in school and during first recess and lunch/second recess were examined using an accelerometer (Kenz Lifecorder GS 4-second version; Suzuken Co. Ltd, Nagoya, Japan).
Results After excluding missing data (moving school; n?=?8, physical activity; n?=?8), 87 (43 boys and 44 girls) of whom were included in the final analysis. Step counts and MVPA during school and physical education in boys did not decrease across the school years. By contrast, in girls, step counts during school did not decrease across the school years, however MVPA did decrease. In addition, for both sexes, step counts and MVPA during first recess decrease across the school years. During lunch/second recess, only step counts decrease across the school years in both sexes. In addition, the tracking coefficients for step counts and MVPA for boys in school and during first recess and lunch/second recess were found across many school years. Contrarily, girls had fewer significant tracking coefficients between school years than boys. There were also few significant tracking coefficients between grades for physical education step counts and MVPA for both boys and girls.
Conclusions Our results suggested that in-school step counts for both boys and girls does not decrease across the school years. However, given that girls demonstrated reduced levels of in-school MVPA across the school years, it is important to promote strategies to increase MVPA in this group. en-copyright= kn-copyright= en-aut-name=SasayamaKensaku en-aut-sei=Sasayama en-aut-mei=Kensaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YasunebeJin en-aut-sei=Yasunebe en-aut-mei=Jin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AdachiMinoru en-aut-sei=Adachi en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Education, Mie University kn-affil= affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Education, Okayama University kn-affil= en-keyword=Physical activity kn-keyword=Physical activity en-keyword=Step counts kn-keyword=Step counts en-keyword=Moderate-to-vigorous physical activity kn-keyword=Moderate-to-vigorous physical activity en-keyword=Youth kn-keyword=Youth en-keyword=Recess kn-keyword=Recess en-keyword=Physical education kn-keyword=Physical education en-keyword=Longitudinal study kn-keyword=Longitudinal study en-keyword=Tracking kn-keyword=Tracking END start-ver=1.4 cd-journal=joma no-vol=36 cd-vols= no-issue=12 article-no= start-page=4932 end-page=4951 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241021 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The leucine-rich repeat receptor kinase QSK1 regulates PRR-RBOHD complexes targeted by the bacterial effector HopF2Pto en-subtitle= kn-subtitle= en-abstract= kn-abstract=Plants detect pathogens using cell-surface pattern recognition receptors (PRRs) such as ELONGATION Factor-TU (EF-TU) RECEPTOR (EFR) and FLAGELLIN SENSING 2 (FLS2), which recognize bacterial EF-Tu and flagellin, respectively. These PRRs belong to the leucine-rich repeat receptor kinase (LRR-RK) family and activate the production of reactive oxygen species via the NADPH oxidase RESPIRATORY BURST OXIDASE HOMOLOG D (RBOHD). The PRR-RBOHD complex is tightly regulated to prevent unwarranted or exaggerated immune responses. However, certain pathogen effectors can subvert these regulatory mechanisms, thereby suppressing plant immunity. To elucidate the intricate dynamics of the PRR-RBOHD complex, we conducted a comparative coimmunoprecipitation analysis using EFR, FLS2, and RBOHD in Arabidopsis thaliana. We identified QIAN SHOU KINASE 1 (QSK1), an LRR-RK, as a PRR-RBOHD complex-associated protein. QSK1 downregulated FLS2 and EFR abundance, functioning as a negative regulator of PRR-triggered immunity (PTI). QSK1 was targeted by the bacterial effector HopF2Pto, a mono-ADP ribosyltransferase, reducing FLS2 and EFR levels through both transcriptional and transcription-independent pathways, thereby inhibiting PTI. Furthermore, HopF2Pto transcriptionally downregulated PROSCOOP genes encoding important stress-regulated phytocytokines and their receptor MALE DISCOVERER 1-INTERACTING RECEPTOR-LIKE KINASE 2. Importantly, HopF2Pto requires QSK1 for its accumulation and virulence functions within plants. In summary, our results provide insights into the mechanism by which HopF2Pto employs QSK1 to desensitize plants to pathogen attack. en-copyright= kn-copyright= en-aut-name=GotoYukihisa

Sediment Microbial Fuel Cells on CH4 and CO2 Emissions from Straw Amended Paddy Soil en-subtitle= kn-subtitle= en-abstract= kn-abstract=Straw returning into paddy soil enhances soil organic matter which usually promotes the emission of greenhouse gases to the atmosphere. The application of sediment microbial fuel cells (SMFCs) to paddy soil activates power-generating microorganisms and enhances organic matter biodegradation. In the present study, rice straw addition in SMFCs was examined to determine its effect on CH4 and CO2 emissions. Columns (height, 25?cm; inner diameter, 9?cm) with four treatments: soil without and with rice straw under SMFC and without SMFC conditions were incubated at 25°C for 70 days. Anodic potential values at 7?cm depth sediment were kept higher by SMFCs than those without SMFCs. Cumulative CH4 emission was significantly reduced by SMFC with straw amendment (p < 0.05) with no significant effect on CO2 emission. 16S rRNA gene analysis results showed that Firmicutes at the phylum, Closteridiales and Acidobacteriales at order level were dominant on the anode of straw-added SMFC, whereas Methanomicrobiales were in the treatment without SMFC, indicating that a certain group of methanogens were suppressed by SMFC. Our results suggest that the anodic redox environment together with the enrichment of straw-degrading bacteria contributed to a competitive advantage of electrogenesis over methanogenesis in straw-added SMFC system. en-copyright= kn-copyright= en-aut-name=BekeleAdhena Tesfau en-aut-sei=Bekele en-aut-mei=Adhena Tesfau kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaMorihiro en-aut-sei=Maeda en-aut-mei=Morihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AkaoSatoshi en-aut-sei=Akao en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SomuraHiroaki en-aut-sei=Somura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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=Faculty of Science and Engineering, Doshisha University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Organization for Research Strategy and Development, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=straw kn-keyword=straw en-keyword=methane mitigation kn-keyword=methane mitigation en-keyword=SMFC kn-keyword=SMFC en-keyword=microorganisms kn-keyword=microorganisms en-keyword=current generation kn-keyword=current generation END start-ver=1.4 cd-journal=joma no-vol=60 cd-vols= no-issue=76 article-no= start-page=10544 end-page=10547 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Investigating the radical properties of oxidized carbon materials under photo-irradiation: behavior of carbon radicals and their application in catalytic reactions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Oxidized carbon materials have abundant surface functional groups and customizable properties, making them an excellent platform for generating radicals.

Among the various oxidized carbon materials synthesized, graphene oxide shows the largest number of carbon radicals when exposed to blue LED light. The light absorption capacity, high surface area, and unique structural characteristics of oxidized carbon materials offer a unique function for radical-mediated oxidative reactions. en-copyright= kn-copyright= en-aut-name=AhmedMd Razu en-aut-sei=Ahmed en-aut-mei=Md Razu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AnayaIsrael Ortiz en-aut-sei=Anaya en-aut-mei=Israel Ortiz 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= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=1 article-no= start-page=35 end-page=50 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250724 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A New Approach to Economic Ripple Effects in Regional Input-Output Tables kn-title=地域産業連関表における経済波及効果のNew Approach en-subtitle= kn-subtitle= en-abstract=　This paper first addresses the concept of economic ripple effects, highlighting that simulation results based on input-output tables often lead to overestimations. The primary reason for this overestimation lies in a misunderstanding of the underlying assumptions that generate ripple effects. Specifically, household consumption within a given region merely represents a transfer of money rather than a genuine economic impact. In principle, ripple effects should be understood as additional consumption resulting from increased income. In the absence of income growth, such effects largely represent consumption substitution or intertemporal shifts in spending. Furthermore, what is commonly referred to as “economic impact” is typically calculated as the cumulative total of sales revenue, which aggregates all monetary transactions indiscriminately. This approach differs from the concept of value-added effects, or income effects, which cannot exceed the initial inflow of money from outside the region. One of the factors contributing to these misinterpretations is the insufficient education on input-output analysis at universities. Additionally, computational tools provided by think tanks and public institutions for estimating ripple effects also present methodological issues. To address these challenges, this paper further refines a model previously proposed by the author that visualizes the ripple effect process. The study demonstrates, using real-world examples, the process of constructing ex-post input-output tables following exogenous impacts such as events. In particular, the paper introduces a “partially non-competitive import type” input structure as an alternative to the conventional competitive import-type input-output tables, which tend to overestimate the effects of changes in self-sufficiency rates. This new approach offers a more accurate framework for analyzing economic impacts. kn-abstract=　本稿では，まず経済波及効果の考え方について，産業連関表を用いたシミュレーションの結果が，しばしば過大評価になっていることを述べる。その理由として，経済波及効果をもたらす前提条件の考え方にしばしば誤解があることを指摘する。域内の居住者の消費はマネーの移転であり，真の経済効果ではない。波及効果とは，本来，所得が増えた結果の追加消費であって，所得が増えない状況では，代替消費や消費の先取りに過ぎないのである。また，一般にいう経済効果とは，売上高の積み上げであって同じマネーが何でも加算されているものであり，付加価値効果すなわち所得効果とは異なる。付加価値効果は，当初の域外から入ってきたマネー以上にはならない。こういった解釈の誤謬をもたらしているのは，大学での産業連関分析の教育が十分でないことも原因の1つであるが，シンクタンクや公的機関などで提供されている波及効果の計算ツールにも問題がある。そこで本稿では，これまで筆者が提唱してきた波及効果プロセスを見える化するモデルを更に精緻化し，イベントなど外生的インパクトが発生した後の事後的な産業連関表を構築する流れに関して実例を用いて説明を行う。特に自給率の変化の効果については，これまでの競争移入型連関表では効果が過大傾向になる問題点を解消するべく，「部分非競争移入型」の投入構造を提案し，新たな分析方法を提案する。 en-copyright= kn-copyright= en-aut-name=NakamuraRyohei en-aut-sei=Nakamura en-aut-mei=Ryohei kn-aut-name=中村良平 kn-aut-sei=中村 kn-aut-mei=良平 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=351 cd-vols= no-issue= article-no= start-page=199522 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evidence for the replication of a plant rhabdovirus in its arthropod mite vector en-subtitle= kn-subtitle= en-abstract= kn-abstract=Transmission of plant viruses that replicate in the insect vector is known as persistent-propagative manner. However, it remains unclear whether such virus-vector relationships also occur between plant viruses and other biological vectors such as arthropod mites. In this study, we investigated the possible replication of orchid fleck virus (OFV), a segmented plant rhabdovirus, within its mite vector (Brevipalpus californicus s.l.) using quantitative RT-qPCR, western blotting and next-generation sequencing. Time-course RT-qPCR and western blot analyses showed an increasing OFV accumulation pattern in mites after virus acquisition. Since OFV genome expression requires the transcription of polyadenylated mRNAs, polyadenylated RNA fractions extracted from the viruliferous mite samples and OFV-infected plant leaves were used for RNA-seq analysis. In the mite and plant datasets, a large number of sequence reads were aligned to genomic regions of OFV RNA1 and RNA2 corresponding to transcribed viral gene mRNAs. This includes the short polyadenylated transcripts originating from the leader and trailer regions at the ends of the viral genome, which are believed to play a crucial role in viral transcription/replication. In contrast, a low number of reads were mapped to the non-transcribed regions (gene junctions). These results strongly suggested that OFV gene expression occurs both in mites and plants. Additionally, deep sequencing revealed the accumulation of OFV-derived small RNAs in mites, although their size profiles differ from those found in plants. Taken together, our results indicated that OFV replicates within a mite vector and is targeted by the RNA-silencing mechanism. en-copyright= kn-copyright= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujitaMiki en-aut-sei=Fujita en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TelengechPaul en-aut-sei=Telengech en-aut-mei=Paul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaruyamKazuyuki en-aut-sei=Maruyam en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HyodoKiwamu en-aut-sei=Hyodo en-aut-mei=Kiwamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TassiAline Daniele en-aut-sei=Tassi en-aut-mei=Aline Daniele kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OchoaRonald en-aut-sei=Ochoa en-aut-mei=Ronald kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AndikaIda Bagus en-aut-sei=Andika en-aut-mei=Ida Bagus kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SuzukiNobuhiro en-aut-sei=Suzuki en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=6 en-affil=Tropical Research and Education Center, University of Florida kn-affil= affil-num=7 en-affil=Systematic Entomology Laboratory, USDA kn-affil= affil-num=8 en-affil=College of Plant Protection, Northwest A&F University kn-affil= affil-num=9 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= en-keyword=Rhabdovirus kn-keyword=Rhabdovirus en-keyword=Plant kn-keyword=Plant en-keyword=Mite kn-keyword=Mite en-keyword=Vector kn-keyword=Vector en-keyword=Replication kn-keyword=Replication en-keyword=mRNA kn-keyword=mRNA en-keyword=Small RNA kn-keyword=Small RNA END start-ver=1.4 cd-journal=joma no-vol=121 cd-vols= no-issue=5 article-no= start-page=e70046 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250304 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Spider mite tetranins elicit different defense responses in different host habitats en-subtitle= kn-subtitle= en-abstract= kn-abstract=Spider mites (Tetranychus urticae) are a major threat to economically important crops. Here, we investigated the potential of tetranins, in particular Tet3 and Tet4, as T. urticae protein-type elicitors that stimulate plant defense. Truncated Tet3 and Tet4 proteins showed efficacy in activating the defense gene pathogenesis-related 1 (PR1) and inducing phytohormone production in leaves of Phaseolus vulgaris. In particular, Tet3 caused a drastically higher Ca2+ influx in leaves, but a lower reactive oxygen species (ROS) generation compared to other tetranins, whereas Tet4 caused a low Ca2+ influx and a high ROS generation in the host plants. Such specific and non-specific elicitor activities were examined by knockdown of Tet3 and Tet4 expressions in mites, confirming their respective activities and in particular showing that they function additively or synergistically to induce defense responses. Of great interest is the fact that Tet3 and Tet4 expression levels were higher in mites on their preferred host, P. vulgaris, compared to the levels in mites on the less-preferred host, Cucumis sativus, whereas Tet1 and Tet2 were constitutively expressed regardless of their host. Furthermore, mites that had been hosted on C. sativus induced lower levels of PR1 expression, Ca2+ influx and ROS generation, i.e., Tet3- and Tet4-responsive defense responses, in both P. vulgaris and C. sativus leaves compared to the levels induced by mites that had been hosted on P. vulgaris. Taken together, these findings show that selected tetranins respond to variable host cues that may optimize herbivore fitness by altering the anti-mite response of the host plant. en-copyright= kn-copyright= en-aut-name=EndoYukiko en-aut-sei=Endo en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaMiku en-aut-sei=Tanaka en-aut-mei=Miku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UemuraTakuya en-aut-sei=Uemura en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanimuraKaori en-aut-sei=Tanimura en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DesakiYoshitake en-aut-sei=Desaki en-aut-mei=Yoshitake kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OzawaRika en-aut-sei=Ozawa en-aut-mei=Rika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=BonzanoSara en-aut-sei=Bonzano en-aut-mei=Sara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MaffeiMassimo E. en-aut-sei=Maffei en-aut-mei=Massimo E. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShinyaTomonori en-aut-sei=Shinya en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=GalisIvan en-aut-sei=Galis en-aut-mei=Ivan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ArimuraGen‐ichiro en-aut-sei=Arimura en-aut-mei=Gen‐ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Biological Science and Technology, Faculty of Advanced Engineering, Tokyo University of Science kn-affil= affil-num=2 en-affil=Department of Biological Science and Technology, Faculty of Advanced Engineering, Tokyo University of Science kn-affil= affil-num=3 en-affil=Department of Biological Science and Technology, Faculty of Advanced Engineering, Tokyo University of Science kn-affil= affil-num=4 en-affil=Department of Biological Science and Technology, Faculty of Advanced Engineering, Tokyo University of Science kn-affil= affil-num=5 en-affil=Department of Biological Science and Technology, Faculty of Advanced Engineering, Tokyo University of Science kn-affil= affil-num=6 en-affil=Center for Ecological Research, Kyoto University kn-affil= affil-num=7 en-affil=Department of Life Sciences and Systems Biology, Plant Physiology Unit, University of Turin kn-affil= affil-num=8 en-affil=Department of Life Sciences and Systems Biology, Plant Physiology Unit, University of Turin kn-affil= affil-num=9 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=10 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=11 en-affil=Department of Biological Science and Technology, Faculty of Advanced Engineering, Tokyo University of Science kn-affil= en-keyword=Cucumis sativus kn-keyword=Cucumis sativus en-keyword=elicitor kn-keyword=elicitor en-keyword=Phaseolus vulgaris kn-keyword=Phaseolus vulgaris en-keyword=spider mite (Tetranychus urticae) kn-keyword=spider mite (Tetranychus urticae) en-keyword=tetranin kn-keyword=tetranin END start-ver=1.4 cd-journal=joma no-vol=186 cd-vols= no-issue= article-no= start-page=118030 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=(+)-Terrein exerts anti-obesity and anti-diabetic effects by regulating the differentiation and thermogenesis of brown adipocytes in mice fed a high-fat diet en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: (+)-Terrein, a low-molecular-weight secondary metabolite from Aspergillus terreus, inhibits adipocyte differentiation in vitro. However, the precise mechanisms underlying the effects of (+)-terrein on adipocytes remain unclear. We hypothesized that (+)-terrein modulates adipogenesis and glucose homeostasis in obesity and diabetes via anti-inflammatory action and regulation of adipocyte differentiation. Hence, in this study, we aimed to investigate the in vivo anti-diabetic and anti-obesity effects of (+)-terrein.
Methods: Male C57BL/6?J mice were fed normal chow or high-fat (HF) diet and administered (+)-terrein (180?mg/kg) via intraperitoneal injection. Glucose and insulin tolerance tests, serum biochemical assays, and histological analyses were also performed. Rat brown preadipocytes, mouse brown preadipocytes (T37i cells), and inguinal white adipose tissue (ingWAT) preadipocytes were exposed to (+)-terrein during in vitro adipocyte differentiation. Molecular markers associated with thermogenesis and differentiation were quantified using real-time polymerase chain reaction and western blotting.
Results: (+)-Terrein-treated mice exhibited improved insulin sensitivity and reduced serum lipid and glucose levels, irrespective of the diet. Furthermore, (+)-terrein suppressed body weight gain and mitigated fat accumulation by activating brown adipose tissue in HF-fed mice. (+)-Terrein facilitated the in vitro differentiation of rat brown preadipocytes, T37i cells, and ingWAT preadipocytes by upregulating peroxisome proliferator-activated receptor-γ (PPARγ). This effect was synergistic with that of a PPARγ agonist.
Conclusion: This study demonstrated that (+)-terrein effectively induces PPARγ expression and brown adipocyte differentiation, leading to reduced weight gain and improved glucose and lipid profiles in HF-fed mice. Thus, (+)-terrein is a potent novel agent with potential anti-obesity and anti-diabetic properties. en-copyright= kn-copyright= en-aut-name=Aoki-SaitoHaruka en-aut-sei=Aoki-Saito en-aut-mei=Haruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MandaiHiroki en-aut-sei=Mandai en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakakuraTakashi en-aut-sei=Nakakura en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SasakiTsutomu en-aut-sei=Sasaki en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KitamuraTadahiro en-aut-sei=Kitamura en-aut-mei=Tadahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=HisadaTakeshi en-aut-sei=Hisada en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkadaShuichi en-aut-sei=Okada en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SugaSeiji en-aut-sei=Suga en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YamadaMasanobu en-aut-sei=Yamada en-aut-mei=Masanobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SaitoTsugumichi en-aut-sei=Saito en-aut-mei=Tsugumichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Allergy and Respiratory Medicine, Gunma University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Pharmacy, Faculty of Pharmacy, Gifu University of Medical Science kn-affil= affil-num=3 en-affil=Department of Anatomy, Teikyo University School of Medicine kn-affil= affil-num=4 en-affil=Division of Food Science and Biotechnology, Graduate School of Agriculture, Kyoto University kn-affil= affil-num=5 en-affil=Metabolic Signal Research Center, Institute for Molecular and Cellular Regulation, Gunma 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=Gunma University Graduate School of Health Sciences kn-affil= affil-num=8 en-affil=Department of Diabetes, Soleiyu Asahi Clinic kn-affil= affil-num=9 en-affil=Division of Applied Chemistry, Graduate School of Natural Sciences and Technology, Okayama University kn-affil= affil-num=10 en-affil=Department of Medicine and Molecular Science, Gunma University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Health & Sports Sciences, Faculty of Education, Tokyo Gakugei University kn-affil= en-keyword=(+)-Terrein kn-keyword=(+)-Terrein en-keyword=Brown adipose tissue kn-keyword=Brown adipose tissue en-keyword=Thermogenesis kn-keyword=Thermogenesis en-keyword=Obesity kn-keyword=Obesity en-keyword=PPARγ kn-keyword=PPARγ END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=12857 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250414 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=OsPIP2;4 aquaporin water channel primarily expressed in roots of rice mediates both water and nonselective Na+ and K+ conductance en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aquaporin (AQP)-dependent water transport across membranes is indispensable in plants. Recent evidence shows that several AQPs, including plasma membrane intrinsic proteins (PIPs), facilitate the electrogenic transport of ions as well as water transport and are referred to as ion-conducting aquaporins (icAQPs). The present study attempted to identify icAQPs that exhibit cation transport activity among PIPs from rice. Electrophysiological experiments on 11 OsPIPs using Xenopus laevis oocytes revealed that OsPIP2;4 mediated the electrogenic transport of alkali monovalent cations with the selectivity sequence of Na+ ? K+ > Rb+ > Cs+ > Li+, suggesting non-selective cation conductance for Na+ and K+. Transcripts of OsPIP2;4 were abundant in the elongation and mature zones of roots with similar expression levels between the root stelar and remaining outer parts in the cultivar Nipponbare. Immunostaining using sections of the crown roots of Nipponbare plants revealed the expression of OsPIP2;4 in the exodermis and sclerenchyma of the surface region and in the endodermis and pericycle of the stelar region. The present results provide novel insights into OsPIP2;4-dependent non-selective Na+ and K+ transport and its physiological roles in rice. en-copyright= kn-copyright= en-aut-name=TranSen Thi Huong en-aut-sei=Tran en-aut-mei=Sen Thi Huong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatsuharaMaki en-aut-sei=Katsuhara en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitoYunosuke en-aut-sei=Mito en-aut-mei=Yunosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OnishiAya en-aut-sei=Onishi en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HigaAyaka en-aut-sei=Higa en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OnoShuntaro en-aut-sei=Ono en-aut-mei=Shuntaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=PaulNewton Chandra en-aut-sei=Paul en-aut-mei=Newton Chandra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HorieRie en-aut-sei=Horie en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HaradaYoshihiko en-aut-sei=Harada en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HorieTomoaki en-aut-sei=Horie en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Division of Applied Biology, Faculty of Textile Science and Technology, Shinshu University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Division of Applied Biology, Faculty of Textile Science and Technology, Shinshu University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=8 en-affil=Division of Applied Biology, Faculty of Textile Science and Technology, Shinshu University kn-affil= affil-num=9 en-affil=Division of Applied Biology, Faculty of Textile Science and Technology, Shinshu University kn-affil= affil-num=10 en-affil=Division of Applied Biology, Faculty of Textile Science and Technology, Shinshu University kn-affil= en-keyword=Ion-conducting Aquaporins kn-keyword=Ion-conducting Aquaporins en-keyword=Non-selective cation channel kn-keyword=Non-selective cation channel en-keyword=Rice kn-keyword=Rice en-keyword=Roots kn-keyword=Roots END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=23758 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250715 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Automated identification of the origin of energy loss in nonoriented electrical steel by feature extended Ginzburg?Landau free energy framework en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study presents the automated identification of the complex magnetization reversal process in nonoriented electrical steel (NOES) using the feature extended Ginzburg?Landau (eX-GL) free energy framework. eX-GL provides a robust connection between microscopic magnetic domains and macroscopic magnetic hysteresis using a data science perspective. This method employs physically meaningful features to analyze the energy landscape, providing insights into the mechanisms behind function. We obtained features representing both the microstructure and energy of the domain wall. The causes of iron loss were traced to the original domain structure, through which we could successfully distinguish and visualize the role of pinning as a promoting and resisting factor. We found that the reversal process was governed not only by general grain boundary pinning but also by segmented magnetic domains within the grain. This method revealed the complex interplay between magnetism and metallography and introduced a new means for transformative material design, bridging structures and functions. en-copyright= kn-copyright= en-aut-name=TaniwakiMichiki en-aut-sei=Taniwaki en-aut-mei=Michiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NagaokaRyunosuke en-aut-sei=Nagaoka en-aut-mei=Ryunosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MasuzawaKen en-aut-sei=Masuzawa en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatoShunsuke en-aut-sei=Sato en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FoggiattoAlexandre Lira en-aut-sei=Foggiatto en-aut-mei=Alexandre Lira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MitsumataChiharu en-aut-sei=Mitsumata en-aut-mei=Chiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamazakiTakahiro en-aut-sei=Yamazaki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ObayashiIppei en-aut-sei=Obayashi en-aut-mei=Ippei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HiraokaYasuaki en-aut-sei=Hiraoka en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IgarashiYasuhiko en-aut-sei=Igarashi en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MizutoriYuta en-aut-sei=Mizutori en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HosseinSepehri Amin en-aut-sei=Hossein en-aut-mei=Sepehri Amin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OhkuboTadakatsu en-aut-sei=Ohkubo en-aut-mei=Tadakatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MogiHisashi en-aut-sei=Mogi en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=KotsugiMasato en-aut-sei=Kotsugi en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Tokyo University of Science kn-affil= affil-num=2 en-affil=Tokyo University of Science kn-affil= affil-num=3 en-affil=Tokyo University of Science kn-affil= affil-num=4 en-affil=Tokyo University of Science kn-affil= affil-num=5 en-affil=Tokyo University of Science kn-affil= affil-num=6 en-affil=Tokyo University of Science kn-affil= affil-num=7 en-affil=Tokyo University of Science kn-affil= affil-num=8 en-affil=Okayama University kn-affil= affil-num=9 en-affil=Kyoto University kn-affil= affil-num=10 en-affil=University of Tsukuba kn-affil= affil-num=11 en-affil=University of Tsukuba kn-affil= affil-num=12 en-affil=NIMS kn-affil= affil-num=13 en-affil=NIMS kn-affil= affil-num=14 en-affil=Nippon Steel kn-affil= affil-num=15 en-affil=Tokyo University of Science kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Amino Acid Substitutions in Loop C of Arabidopsis PIP2 Aquaporins Alters the Permeability of CO2 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The transport of CO2 across biomembranes in plant cells is essential for efficient photosynthesis. Some aquaporins capable of CO2 transport, referred to as ‘COOporins’, are postulated to play a crucial role in leaf CO2 diffusion. However, the structural basis of CO2 permeation through aquaporins remains largely unknown. Here, we show that amino acids in loop C are critical for the CO2 permeability of Arabidopsis thaliana PIP2 aquaporins. We found that swapping tyrosine and serine in loop C to histidine and phenylalanine, which differ between AtPIP2;1 and AtPIP2;3, altered CO2 permeability when examined in the Xenopus laevis oocyte heterologous expression system. AlphaFold2 modelling indicated that these substitution induced a conformational shift in the sidechain of arginine in the aromatic/arginine (ar/R) selectivity filter and in lysine at the extracellular mouth of the monomeric pore in PIP2 aquaporins. Our findings demonstrate that distal amino acid substitutions can trigger conformational changes of the ar/R filter in the monomeric pore, modulating CO2 permeability. Additionally, phylogenetic analysis suggested that aquaporins capable of dual water/CO2 permeability are ancestral to those that are water-selective and CO2-impermeable, and CO2-selective and water impermeable. en-copyright= kn-copyright= en-aut-name=TaniaShaila Shermin en-aut-sei=Tania en-aut-mei=Shaila Shermin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UtsugiShigeko en-aut-sei=Utsugi en-aut-mei=Shigeko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsuchiyaYoshiyuki en-aut-sei=Tsuchiya en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SasanoShizuka en-aut-sei=Sasano en-aut-mei=Shizuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatsuharaMaki en-aut-sei=Katsuhara en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MoriIzumi C. en-aut-sei=Mori en-aut-mei=Izumi C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Arabidopsis thaliana kn-keyword=Arabidopsis thaliana en-keyword=CO2 transport kn-keyword=CO2 transport en-keyword=monomeric pore kn-keyword=monomeric pore en-keyword=PIP2 aquaporin kn-keyword=PIP2 aquaporin en-keyword=Xenopus laevis kn-keyword=Xenopus laevis END start-ver=1.4 cd-journal=joma no-vol=158 cd-vols= no-issue= article-no= start-page=107932 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=Trends in nontuberculous mycobacterial disease mortality based on 2000-2022 data from 83 countries en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: To examine the international trends for nontuberculous mycobacterial-associated mortality rates, as nontuberculous mycobacterial infections are becoming increasingly prevalent and pose a significant public health challenge, especially in older populations.
Methods: This retrospective observational study used data from the World Health Organization mortality database, which included patients with nontuberculous mycobacterial infection in 83 countries. We stratified the data by sex, age, and geographic region and calculated crude and age-standardized mortality rates to estimate long-term mortality trends.
Results: In total, 42,182 nontuberculous mycobacterial infection-associated deaths (58.1% in women) were reported in 83 countries between 2000 and 2022. The locally weighted regression model estimation for the nontuberculous mycobacterial infection-associated mortality rate more than doubled?from 0.36 deaths per 1000,000 individuals in 2000 to 0.77 deaths per 1000,000 individuals in 2022. Eighty-six percent of nontuberculous mycobacterial infection-associated deaths occurred in people aged ?65 years. The mortality rate was the highest in the Western Pacific Region.
Conclusion: This study highlights the impact of emerging nontuberculous mycobacterial diseases and the importance of targeted interventions for managing and reducing mortality, particularly in vulnerable older populations. Further studies are warranted to determine the factors contributing to geographical disparity and treatment options. en-copyright= kn-copyright= en-aut-name=HaradaKo en-aut-sei=Harada en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=VuQuynh Thi en-aut-sei=Vu en-aut-mei=Quynh Thi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakedaTatsuaki en-aut-sei=Takeda en-aut-mei=Tatsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=MinatoYusuke en-aut-sei=Minato en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=KoyamaToshihiro en-aut-sei=Koyama en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= affil-num=1 en-affil=Brookdale Department of Geriatrics and Palliative Medicine, Icahn School of Medicine at Mount Sinai kn-affil= affil-num=2 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Division of Hematology/Oncology, Mayo Clinic kn-affil= affil-num=4 en-affil=Department of Education and Research Centre for Clinical Pharmacy, Faculty of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=6 en-affil=Center for Infectious Disease Research, Fujita Health University kn-affil= affil-num=7 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= en-keyword=Population surveillance kn-keyword=Population surveillance en-keyword=Mortality kn-keyword=Mortality en-keyword=Nontuberculous mycobacterial infections kn-keyword=Nontuberculous mycobacterial infections END start-ver=1.4 cd-journal=joma no-vol=965 cd-vols= no-issue=1 article-no= start-page=52 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Unraveling the Cr Isotopes of Ryugu: An Accurate Aqueous Alteration Age and the Least Thermally Processed Solar System Material en-subtitle= kn-subtitle= en-abstract= kn-abstract=The analysis of samples returned from the C-type asteroid Ryugu has drastically advanced our knowledge of the evolution of early solar system materials. However, no consensus has been obtained on the chronological data, which is important for understanding the evolution of the asteroid Ryugu. Here, the aqueous alteration age of Ryugu particles was determined by the Mn?Cr method using bulk samples, yielding an age of 4.13 + 0.62/?0.55 Myr after the formation of Ca?Al-rich inclusions (CAI). The age corresponds to 4563.17 + 0.60/?0.67 Myr ago. The higher 55Mn/52Cr, ε54Cr, and initial ε53Cr values of the Ryugu samples relative to any carbonaceous chondrite samples implies that its progenitor body formed from the least thermally processed precursors in the outermost region of the protoplanetary disk. Despite accreting at different distances from the Sun, the hydrous asteroids (Ryugu and the parent bodies of CI, CM, CR, and ungrouped C2 meteorites) underwent aqueous alteration during a period of limited duration (3.8 ± 1.8 Myr after CAI). These ages are identical to the crystallization age of the carbonaceous achondirtes NWA 6704/6693 within the error. The ε54Cr and initial ε53Cr values of Ryugu and NWA 6704/6693 are also identical, while they show distinct Δ'17O values. This suggests that the precursors that formed the progenitor bodies of Ryugu and NWA 6703/6693 were formed in close proximity and experienced a similar degree of thermal processing in the protosolar nebula. However, the progenitor body of Ryugu was formed by a higher ice/dust ratio, than NWA6703/6693, in the outer region of the protoplanetary disk. en-copyright= kn-copyright= en-aut-name=TanakaRyoji

kn-subtitle= en-abstract= kn-abstract=The reaction center-light harvesting 1 (RC-LH1) complex converts solar energy into electrical energy, driving the initiation of photosynthesis. The authors present a cryo-electron microscopy structure of the RC-LH1 isolated from a marine photoheterotrophic bacterium Dinoroseobacter shibae. The RC comprises four subunits, including a three-heme cytochrome (Cyt) c protein, and is surrounded by a closed LH ring composed of 17 pairs of antenna subunits. Notably, a novel subunit with an N-terminal “helix-turn-helix” motif embedded in the gap between the RC and the LH ring is identified. The purified RC-LH1 complex exhibits high stability in solutions containing Mg2+ or Ca2+. The periplasmic Cyt c2 is predicted to bind at the junction between the Cyt subunit and the membrane plane, enabling electron transfer from Cyt c2 to the proximal heme of the tri-heme Cyt, and subsequently to the special pair of bacteriochlorophylls. These findings provide structural insights into the efficient energy and electron transfer processes within a distinct type of RC-LH1, and shed light on evolutionary adaptations of photosynthesis. en-copyright= kn-copyright= en-aut-name=WangWeiwei en-aut-sei=Wang en-aut-mei=Weiwei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LiuYanting en-aut-sei=Liu en-aut-mei=Yanting kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GuJiayi en-aut-sei=Gu en-aut-mei=Jiayi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AnShaoya en-aut-sei=An en-aut-mei=Shaoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaCheng en-aut-sei=Ma en-aut-mei=Cheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GaoHaichun en-aut-sei=Gao en-aut-mei=Haichun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=JiaoNianzhi en-aut-sei=Jiao en-aut-mei=Nianzhi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShenJian‐Ren en-aut-sei=Shen en-aut-mei=Jian‐Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=BeattyJohn Thomas en-aut-sei=Beatty en-aut-mei=John Thomas kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=Kobl??ekMichal en-aut-sei=Kobl??ek en-aut-mei=Michal kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ZhangXing en-aut-sei=Zhang en-aut-mei=Xing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ZhengQiang en-aut-sei=Zheng en-aut-mei=Qiang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=ChenJing‐Hua en-aut-sei=Chen en-aut-mei=Jing‐Hua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=College of Life Sciences, Zhejiang University kn-affil= affil-num=2 en-affil=State Key Laboratory of Marine Environmental Science, College of Ocean and Earth Sciences, Xiamen University kn-affil= affil-num=3 en-affil=College of Life Sciences, Zhejiang University kn-affil= affil-num=4 en-affil=Department of Pathology of Sir Run Run Shaw Hospital, Department of Biophysics, Zhejiang University School of Medicine kn-affil= affil-num=5 en-affil=Department of Pathology of Sir Run Run Shaw Hospital, Department of Biophysics, Zhejiang University School of Medicine kn-affil= affil-num=6 en-affil=College of Life Sciences, Zhejiang University kn-affil= affil-num=7 en-affil=State Key Laboratory of Marine Environmental Science, College of Ocean and Earth Sciences, Xiamen University kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, and Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Department of Microbiology & Immunology, University of British Columbia kn-affil= affil-num=10 en-affil=Laboratory of Anoxygenic Phototrophs, Institute of Microbiology, Czech Academy of Science kn-affil= affil-num=11 en-affil=Department of Pathology of Sir Run Run Shaw Hospital, Department of Biophysics, Zhejiang University School of Medicine kn-affil= affil-num=12 en-affil=State Key Laboratory of Marine Environmental Science, College of Ocean and Earth Sciences, Xiamen University kn-affil= affil-num=13 en-affil=College of Life Sciences, Zhejiang University kn-affil= en-keyword=energy transfer kn-keyword=energy transfer en-keyword=photoheterotrophic bacteria kn-keyword=photoheterotrophic bacteria en-keyword=photosynthesis kn-keyword=photosynthesis en-keyword=reaction center kn-keyword=reaction center en-keyword=structure kn-keyword=structure END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=3 article-no= start-page=e70143 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250625 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Factors Influencing Pain Management Practices Among Nurses in University Hospitals in Western Japan: A Cross‐Sectional Study Using Hierarchical Multiple Regression Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Effective pain management remains a global nursing challenge, requiring awareness of influencing factors. This cross-sectional study examined such factors among nurses in Western Japan's university hospitals from September to November 2023. A self-reported questionnaire was used to investigate nurses' sociodemographic characteristics, collaboration with physicians in the ward, pain management knowledge, empathy, and pain management practices. Among 695 nurses (69.4% valid response rate), 51.4% had under 5?years' work experience, indicating a relatively junior nursing workforce. The mean practice score was 47.5 (SD?=?7.1).

Materials and Methods: We performed comprehensive transcriptome data analysis and subsequent functional validation of the human Skin Cutaneous Melanoma project from The Cancer Genome Atlas (TCGA).
Results: Elevated expression levels of C1orf50 correlated with worse survival outcomes. Mechanistically, we revealed that C1orf50 plays a significant role in the regulation of cell cycle processes and cancer cell stemness, providing a potential avenue for novel therapeutic interventions in melanoma.
Conclusion: This study is the first to identify C1orf50 as a prognostic biomarker in melanoma. The clinical relevance of our results sheds light on the importance of further investigation into the biological mechanisms underpinning C1orf50’s impact on melanoma progression and patient prognosis. en-copyright= kn-copyright= en-aut-name=OTANIYUSUKE en-aut-sei=OTANI en-aut-mei=YUSUKE kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MAEKAWAMASAKI en-aut-sei=MAEKAWA en-aut-mei=MASAKI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TANAKAATSUSHI en-aut-sei=TANAKA en-aut-mei=ATSUSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=PE?ATIRSO en-aut-sei=PE?A en-aut-mei=TIRSO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=CHINVANESSA D. en-aut-sei=CHIN en-aut-mei=VANESSA D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ROGACHEVSKAYAANNA en-aut-sei=ROGACHEVSKAYA en-aut-mei=ANNA kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TOYOOKASHINICHI en-aut-sei=TOYOOKA en-aut-mei=SHINICHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ROEHRLMICHAEL H. en-aut-sei=ROEHRL en-aut-mei=MICHAEL H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FUJIMURAATSUSHI en-aut-sei=FUJIMURA en-aut-mei=ATSUSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=2 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=3 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=4 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=5 en-affil=UMass Chan Medical School, UMass Memorial Medical Center kn-affil= affil-num=6 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=9 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=C1orf50 kn-keyword=C1orf50 en-keyword=melanoma kn-keyword=melanoma en-keyword=cancer stem cells kn-keyword=cancer stem cells en-keyword=YAP/TAZ kn-keyword=YAP/TAZ END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=6 article-no= start-page=e70126 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sulphur‐Acquisition Pathways for Cysteine Synthesis Confer a Fitness Advantage to Bacteria in Plant Extracts en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bacteria and plants are closely associated with human society, in fields such as agriculture, public health, the food industry, and waste disposal. Bacteria have evolved nutrient-utilisation systems adapted to achieve the most efficient growth in their major habitats. However, empirical evidence to support the significance of bacterial nutrient utilisation in adaptation to plants is limited. Therefore, we investigated the genetic and nutritional factors required for bacterial growth in plant extracts by screening an Escherichia coli gene-knockout library in vegetable-based medium. Mutants lacking genes involved in sulphur assimilation, whereby sulphur is transferred from sulphate to cysteine, exhibited negligible growth in vegetable-based medium or plant extracts, owing to the low cysteine levels. The reverse transsulphuration pathway from methionine, another pathway for donating sulphur to cysteine, occurring in bacteria such as Bacillus subtilis, also played an important role in growth in plant extracts. These two sulphur-assimilation pathways were more frequently observed in plant-associated than in animal-associated bacteria. Sulphur-acquisition pathways for cysteine synthesis thus play a key role in bacterial growth in plant-derived environments such as plant residues and plant exudates. en-copyright= kn-copyright= en-aut-name=IshikawaKazuya en-aut-sei=Ishikawa en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamaguchiSaki en-aut-sei=Yamaguchi en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsukaokaTaketo en-aut-sei=Tsukaoka en-aut-mei=Taketo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsunodaMakoto en-aut-sei=Tsunoda en-aut-mei=Makoto 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=Graduate School of Pharmaceutical Sciences, The University of Tokyo 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=Bacillus subtilis kn-keyword=Bacillus subtilis en-keyword=bacterial nutrient utilisation kn-keyword=bacterial nutrient utilisation en-keyword=cysteine synthesis kn-keyword=cysteine synthesis en-keyword=Escherichia coli kn-keyword=Escherichia coli en-keyword=plant-derived environments kn-keyword=plant-derived environments en-keyword=sulphur acquisition pathway kn-keyword=sulphur acquisition pathway END start-ver=1.4 cd-journal=joma no-vol=227 cd-vols= no-issue= article-no= start-page=110168 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=The hidden cation-selective pore in ion-conducting aquaporin OsPIP2;4 from rice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ion-conducting aquaporins (icAQPs) transport ions as well as water. Although the molecular mechanism of how AQPs establish selective permeability for water molecules is well understood, the ion-transporting mechanism in icAQPs has not yet been fully elucidated. In this study, we investigated the molecular mechanism of cation transport in OsPIP2;4, an icAQP in rice, by homology modeling and the electrophysiological analysis using Xenopus laevis oocytes. Water and ion transport assays using OsPIP2;4 T227M and G278K mutants strongly suggested that water- and cation-transporting pathways are independent of each other. Data from amino acid substitutions V54I and A143G in OsPIP2;4 led to the identification of a novel hidden pathway for cation transport located on the side surfaces of the tetramer channel, where two protomers are in contact, which is distinct from conventional monomeric pores and the tetrameric central pore in AQPs. Moreover, the present results provide the possibility that this hypothetical hidden pore also functions in the barley icAQP HvPIP2;8. The overall structure of this novel pathway appears to differ from the structure of general cation channels. However, the arrangement of hydrophilic amino acids at the entrance of the pathway of OsPIP2;4 was found to be comparable to that of some cation channels, which implies that the molecular mechanism of dehydration of hydrated ions might resemble that of the channels. Although direct structural evidence is needed to confirm the proposed pathway, the present study can be a stepping stone toward unraveling the mechanism of dual water and ion transport through icAQPs in plants. en-copyright= kn-copyright= en-aut-name=OnoShuntaro en-aut-sei=Ono en-aut-mei=Shuntaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TranSen Thi Huong en-aut-sei=Tran en-aut-mei=Sen Thi Huong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SaitohYasunori en-aut-sei=Saitoh en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UtsugiShigeko en-aut-sei=Utsugi en-aut-mei=Shigeko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HorieTomoaki en-aut-sei=Horie en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatsuharaMaki en-aut-sei=Katsuhara en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Division of Applied Biology, Faculty of Textile Science and Technology, Shinshu University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Rice kn-keyword=Rice en-keyword=Barley kn-keyword=Barley en-keyword=Ion transport kn-keyword=Ion transport en-keyword=Ion-conducting aquaporin (icAQP) kn-keyword=Ion-conducting aquaporin (icAQP) en-keyword=Plasma membrane intrinsic protein (PIP) kn-keyword=Plasma membrane intrinsic protein (PIP) END start-ver=1.4 cd-journal=joma no-vol=301 cd-vols= no-issue=7 article-no= start-page=110291 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=A repertoire of visible light?sensitive opsins in the deep-sea hydrothermal vent shrimp Rimicaris hybisae en-subtitle= kn-subtitle= en-abstract= kn-abstract=Unlike terrestrial environments, where humans reside, there is no sunlight in the deep sea. Instead, dim visible light from black-body radiation and bioluminescence illuminates hydrothermal vent areas in the deep sea. A deep-sea hydrothermal vent shrimp, Rimicaris hybisae, is thought to detect this dim light using its enlarged dorsal eye; however, the molecular basis of its photoreception remains unexplored. Here, we characterized the molecular properties of opsins, universal photoreceptive proteins in animals, found in R. hybisae. Transcriptomic analysis identified six opsins: three Gq-coupled opsins, one Opn3, one Opn5, and one peropsin. Functional analysis revealed that five of these opsins exhibited light-dependent G protein activity, whereas peropsin exhibited the ability to convert all-trans-retinal to 11-cis-retinal like photoisomerases. Notably, all the R. hybisae opsins, including Opn5, convergently show visible light sensitivity (around 457?517 nm), whereas most opsins categorized as Opn5 have been demonstrated to be UV sensitive. Mutational analysis revealed that the unique visible light sensitivity of R. hybisae Opn5 is achieved through the stabilization of a protonated Schiff base by a counterion residue at position 83 (Asp83), which differs from the position identified in other opsins. These findings suggest that the vent shrimp R. hybisae has adapted its photoreceptive devices to dim deep-sea hydrothermal light by selectively maintaining a repertoire of visible light?sensitive opsins, including the uniquely tuned Opn5. en-copyright= kn-copyright= en-aut-name=NagataYuya en-aut-sei=Nagata en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

Male, but not female NMU KO rats exhibited decreased wheel-running activity vs wildtype (WT), although overall home cage activity was not affected. Plasma testosterone in WT rats varied significantly over the course of a day, with a peak at ZT1 and a nadir at ZT18, whereas in NMU KO rats testosterone remained stable throughout the day. Chronic administration of testosterone restored wheel-running activity in NMU KO rats to the same level as in WT rats, suggesting that the decrease in wheel-running activity in NMU KO rats is due to the disruption of the diurnal change of testosterone. Accordingly, expression of the luteinizing hormone beta subunit (Lhb) mRNA in the pars distalis of anterior pituitary was significantly lower in NMU KO rats; immunostaining revealed that the size of luteinizing hormone (LH)?expressing cells was also relatively small in those animals. In the brain of male WT rats, Nmu was highly expressed in the pars tuberalis, and the NMU receptor Nmur2 was highly expressed in the ependymal cell layer of the third ventricle. This study reveals a novel function of NMU and indicates that endogenous NMU in rats plays a role in the regulation of motivated activity via regulation of testosterone. en-copyright= kn-copyright= en-aut-name=OtsukaMai en-aut-sei=Otsuka en-aut-mei=Mai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeuchiYu en-aut-sei=Takeuchi en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoriyamaMaho en-aut-sei=Moriyama en-aut-mei=Maho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EgoshiSakura en-aut-sei=Egoshi en-aut-mei=Sakura kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GotoYuki en-aut-sei=Goto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GuTingting en-aut-sei=Gu en-aut-mei=Tingting kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KimuraAtsushi P en-aut-sei=Kimura en-aut-mei=Atsushi P kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HaraguchiShogo en-aut-sei=Haraguchi en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YoshiiTaishi en-aut-sei=Yoshii en-aut-mei=Taishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=MatsuyamaMakoto en-aut-sei=Matsuyama en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=BentleyGeorge E en-aut-sei=Bentley en-aut-mei=George E kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Biology, Faculty of Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Department of Biological Sciences, Faculty of Science, Hokkaido University kn-affil= affil-num=8 en-affil=Department of Biochemistry, Showa University School of Medicine kn-affil= affil-num=9 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=10 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=11 en-affil=Division of Molecular Genetics, Shigei Medical Research Institute kn-affil= affil-num=12 en-affil=Department of Integrative Biology and Helen Wills Neuroscience Institute, University of California at Berkeley kn-affil= affil-num=13 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Neuromedin U kn-keyword=Neuromedin U en-keyword=rat kn-keyword=rat en-keyword=motivation kn-keyword=motivation en-keyword=activity kn-keyword=activity en-keyword=testosterone kn-keyword=testosterone en-keyword=wheel-running kn-keyword=wheel-running END start-ver=1.4 cd-journal=joma no-vol=58 cd-vols= no-issue=3 article-no= start-page=976 end-page=991 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=Enhanced estimation method for partial scattering functions in contrast variation small-angle neutron scattering via Gaussian process regression with prior knowledge of smoothness en-subtitle= kn-subtitle= en-abstract= kn-abstract=Contrast variation small-angle neutron scattering (CV-SANS) is a powerful tool for evaluating the structure of multi-component systems. In CV-SANS, the scattering intensities I(Q) measured with different scattering contrasts are de?com?posed into partial scattering functions S(Q) of the self- and cross-correlations between components. Since the measurement has a measurement error, S(Q) must be estimated statistically from I(Q). If no prior knowledge about S(Q) is available, the least-squares method is best, and this is the most popular estimation method. However, if prior knowledge is available, the estimation can be improved using Bayesian inference in a statistically authorized way. In this paper, we propose a novel method to improve the estimation of S(Q), based on Gaussian process regression using prior knowledge about the smoothness and flatness of S(Q). We demonstrate the method using synthetic core?shell and experimental polyrotaxane SANS data. en-copyright= kn-copyright= en-aut-name=ObayashiIppei en-aut-sei=Obayashi en-aut-mei=Ippei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyajimaShinya en-aut-sei=Miyajima en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaKazuaki en-aut-sei=Tanaka en-aut-mei=Kazuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MayumiKoichi en-aut-sei=Mayumi en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Center for Artificial Intelligence and Mathematical Data Science, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Science and Engineering, Iwate University kn-affil= affil-num=3 en-affil=Global Center for Science and Engineering, Waseda University kn-affil= affil-num=4 en-affil=Institute for Solid State Physics, University of Tokyo kn-affil= en-keyword=contrast variation small-angle neutron scattering kn-keyword=contrast variation small-angle neutron scattering en-keyword=CV-SANS kn-keyword=CV-SANS en-keyword=partial scattering functions kn-keyword=partial scattering functions en-keyword=multi-component systems kn-keyword=multi-component systems en-keyword=statistical methods kn-keyword=statistical methods en-keyword=Bayesian inference kn-keyword=Bayesian inference en-keyword=contrast variation kn-keyword=contrast variation en-keyword=Gaussian process regression kn-keyword=Gaussian process regression END start-ver=1.4 cd-journal=joma no-vol=192 cd-vols= no-issue=5 article-no= start-page=58 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250416 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Intertwining Property for Laguerre Processes with a Fixed Parameter en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigate the intertwining of Laguerre processes of parameter α in different dimensions.

However, real-world safety information on pertuzumab remains limited. This study assessed the safety of adding pertuzumab to trastuzumab-based therapy for HER2-positive breast cancer using real-world data.
Methods: VigiBase, the World Health Organization's global database of adverse events (AEs), containing reports from November 1967 to December 2023, was used. Signals for pertuzumab-associated AEs in breast cancer cases were detected using the reporting odds ratio (ROR).
Results: Signals of trastuzumab plus pertuzumab relative to trastuzumab alone were detected in gastrointestinal disorders (ROR: 1.45, 95% confidence interval: 1.26?1.67), including diarrhoea (3.49, 2.83?4.30); infections and infestations (1.54, 1.24?1.91); and skin and subcutaneous tissue disorders (ROR: 1.63, 1.40?1.90), including pruritus (1.96, 1.51?2.55) and rash (1.63, 1.20?2.23). Further, signals of trastuzumab plus docetaxel plus pertuzumab relative to those of trastuzumab plus docetaxel were detected in gastrointestinal disorders (1.63, 1.38?1.93), including nausea (1.72, 1.24?2.39) and vomiting (1.48, 1.01?2.17), and in nervous system disorders (1.50, 1.20?1.87), including paraesthesia (2.60, 1.33?5.08) and peripheral sensory neuropathy (5.94, 1.79?19.71). The frequency of AEs causing or prolonging hospitalization was increased with trastuzumab plus pertuzumab compared to that with trastuzumab alone (1.18, 1.00?1.38).
Conclusions: AE profiles after the addition of pertuzumab to trastuzumab-based therapy were comprehensively identified. The findings in this study highlight the importance of considering these AEs when selecting pertuzumab combination therapy to ensure the safety of patients with breast cancer. en-copyright= kn-copyright= en-aut-name=TakedaTatsuaki en-aut-sei=Takeda en-aut-mei=Tatsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoJun en-aut-sei=Matsumoto en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakaiTomonori en-aut-sei=Sakai en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IwataNaohiro en-aut-sei=Iwata en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=KoyamaToshihiro en-aut-sei=Koyama en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AriyoshiNoritaka en-aut-sei=Ariyoshi en-aut-mei=Noritaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Department of Education and Research Center for Clinical Pharmacy, Faculty of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Education and Research Center for Clinical Pharmacy, Faculty of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Education and Research Center for Clinical Pharmacy, Faculty of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= en-keyword=adverse event kn-keyword=adverse event en-keyword=breast cancer kn-keyword=breast cancer en-keyword=pertuzumab kn-keyword=pertuzumab en-keyword=trastuzumab kn-keyword=trastuzumab en-keyword=VigiBase kn-keyword=VigiBase END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=22 end-page=54 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Forming a mindset of A consideration on being a burden : Relationship with education kn-title=迷惑をかけたくない意識の形成―教育との関係― en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=DENGXiaofan en-aut-sei=DENG en-aut-mei=Xiaofan kn-aut-name=ｹ小凡 kn-aut-sei=ｹ kn-aut-mei=小凡 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院ヘルスシステム統合科学研究科 END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=18 article-no= start-page=4737 end-page=4741 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250429 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electrochemical Oxidation of Benzyl Alcohols via Hydrogen Atom Transfer Mediated by 2,2,2-Trifluoroethanol en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a novel electrochemical oxidation of benzyl alcohols.

GIs that confer pathogenicity and environmental adaptation have been reported in Pseudomonas species; however, GIs that enhance bacterial virulence have not. Here, we identified 110 kb and 103 kb GIs in P. syringae pv. tabaci 6605 (Pta6605), the causative agent of tobacco wildfire disease, which has the ability to produce tabtoxin as a phytotoxin. These GIs are partially homologous to known genomic islands in Pseudomonas aeruginosa and P. syringae pv. phaseolicola and were designated PtaGI-1 and PtaGI-2. Both PtaGIs conserve core genes, whereas each GI possesses different accessory genes. PtaGI-1 contains a tabtoxin biosynthetic gene cluster and three type III effector genes among its accessory genes, whereas PtaGI-2 also contains homologous genes to hsvABC, pathogenicity-related genes in Erwinia amylovora. Inoculation revealed that the PtaGI-1 mutant, but not the PtaGI-2 mutant, lost the ability to biosynthesise tabtoxin and to cause disease. Therefore, PtaGI-1 is thought to be a pathogenicity island. Both PtaGI-1 and PtaGI-2 have a pseudogene of tRNALys on the left border and an intact tRNALys gene on the right border. In a colony of Pta6605, both GIs can be excised at tRNALys, and PtaGI-1 and PtaGI-2 exist in a circular form. These results indicate that tabtoxin biosynthesis genes in PtaGI-1 are required for disease development, and PtaGI-1 is necessary for Pta6605 virulence. en-copyright= kn-copyright= en-aut-name=WatanabeYuta en-aut-sei=Watanabe en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KunishiKotomi en-aut-sei=Kunishi en-aut-mei=Kotomi 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=Faculty of Agriculture,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=horizontal gene transfer kn-keyword=horizontal gene transfer en-keyword=integrative and conjugative elements kn-keyword=integrative and conjugative elements 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=19 cd-vols= no-issue=2 article-no= start-page=94 end-page=100 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 different management approaches on unmet water demand in coffee-producing areas during wet and dry years: a case study of the Srepok River Watershed, Vietnam en-subtitle= kn-subtitle= en-abstract= kn-abstract=The primary cause of conflicts over water allocation is growing demand and limited supply, which has become an increasingly serious issue in many watersheds. To alleviate water disputes, effective management strategies can be employed, particularly in the context of intensifying agricultural production and unpredictable changes in weather. In this study, two models, SWAT and WEAP, and the modified surface water supply index (MSWSI) were utilized to evaluate water allocation in the Srepok River Watershed (SRW), considering the prioritization of demand and various irrigation methods, during both wet and dry years. The crop irrigation was chosen to be the main focus in relation to the unmet water demand (UWD). The results indicated that coffee was the primary cause of UWD in the middle of the watershed during the second half of the dry season, and annual crops (AC) were the secondary cause. This research further elucidated that while prioritizing demand had an insignificant impact, transitioning from hose irrigation to sprinkler irrigation could be remarkably effective in mitigating the issues of UWD in coffee crops during both wet and dry years. en-copyright= kn-copyright= en-aut-name=SamTruong Thao en-aut-sei=Sam en-aut-mei=Truong Thao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SomuraHiroaki en-aut-sei=Somura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoroizumiToshitsugu en-aut-sei=Moroizumi en-aut-mei=Toshitsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= 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= en-keyword=hydrological model kn-keyword=hydrological model en-keyword=drought kn-keyword=drought en-keyword=coffee irrigation kn-keyword=coffee irrigation en-keyword=water-saving technique kn-keyword=water-saving technique en-keyword=water allocation kn-keyword=water allocation END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=1 article-no= start-page=715 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=TRPV2 mediates stress resilience in mouse cardiomyocytes en-subtitle= kn-subtitle= en-abstract= kn-abstract=The heart dynamically compensates for haemodynamic stress, but how this resilience forms during cardiac growth is not clear. Using a temporally inducible, cardiac-specific knockout in mice we show that the Transient receptor potential vanilloid family 2 (TRPV2) channel is crucial for the maturation of cardiomyocyte stress resilience. TRPV2 defects in growing hearts lead to small morphology, abnormal intercalated discs, weak contractility, and low expression of serum response factor and Insulin-like growth factor-1 (IGF-1) signalling. Individual cardiomyocytes of TRPV2-deficient hearts show reduced contractility with abnormal Ca2+ handling. In cultured neonatal cardiomyocytes, mechanical Ca2+ response, excitation-contraction coupling, sarcoplasmic reticulum Ca2+ content, actin formation, nuclear localisation of Myocyte enhancer factor 2c, and IGF-1 expression require TRPV2. TRPV2-deficient hearts show a defective response to dobutamine stress and no compensatory hypertrophic response to phenylephrine administration, but no stress response to pressure overload. These data suggest TRPV2 mediates the maturation of cardiomyocyte stress resilience, and will advance therapeutic interventions and drug discovery for heart disease. en-copyright= kn-copyright= en-aut-name=DongYubing en-aut-sei=Dong en-aut-mei=Yubing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WangGuohao en-aut-sei=Wang en-aut-mei=Guohao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UjiharaYoshihiro en-aut-sei=Ujihara en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChenYanzhu en-aut-sei=Chen en-aut-mei=Yanzhu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshidaMasashi en-aut-sei=Yoshida en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KatanosakaKimiaki en-aut-sei=Katanosaka en-aut-mei=Kimiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NaruseKeiji en-aut-sei=Naruse en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KatanosakaYuki en-aut-sei=Katanosaka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Electrical and Mechanical Engineering, Graduate School of Engineering, Nagoya Institute of Technology kn-affil= affil-num=4 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Chronic Kidney Disease and Cardiovascular Disease, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Biomedical Sciences, College of Life and Health Sciences, Chubu University kn-affil= affil-num=8 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Cardiovascular Physiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=5 article-no= start-page=e70091 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250507 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pseudomonas syringae pv. tabaci 6605 Requires Seven Type III Effectors to Infect Nicotiana benthamiana en-subtitle= kn-subtitle= en-abstract= kn-abstract=Type III effectors (T3Es), virulence factors injected into plant cells via the type III secretion system (T3SS), play essential roles in the infection of host plants. Pseudomonas syringae pv. tabaci 6605 (Pta 6605) is the causal agent of wildfire disease in tobacco and harbours at least 22 T3Es in its genome. However, the specific T3Es required by Pta 6605 to infect Nicotiana benthamiana remain unidentified. In this study, we investigated the T3Es that contribute to Pta 6605 infection of N. benthamiana. We constructed Pta 6605 poly-T3E-deficient mutants (Pta DxE) and inoculated them into N. benthamiana. Flood assay, which mimics natural opening-based entry, showed that mutant strains lacking 14-22 T3Es, namely, Pta D14E-D22E mutants, exhibited reduced disease symptoms. By contrast, infiltration inoculation, which involves direct injection into leaves, showed that the Pta D14E to Pta D20E mutants developed disease symptoms. Notably, the Pta D20E, containing AvrE1 and HopM1, induced weak but observable symptoms upon infiltration inoculation. Conversely, no symptoms were observed in either the flood assay or infiltration inoculation for Pta D21E and Pta D22E. Taken together, these findings indicate that the many T3Es such as AvrPto4/AvrPtoB, HopW1/HopAE1, and HopM1/AvrE1 in Pta 6605 collectively contribute to invasion through natural openings and symptom development in N. benthamiana. This study provides the basis for understanding virulence in the host by identifying the minimum T3E repertoire required by Pta 6605 to infect N. benthamiana. en-copyright= kn-copyright= en-aut-name=KuroeKana en-aut-sei=Kuroe en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimuraTakafumi en-aut-sei=Nishimura en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KashiharaSachi en-aut-sei=Kashihara en-aut-mei=Sachi 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=YamamotoMikihiro en-aut-sei=Yamamoto en-aut-mei=Mikihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 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=8 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=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=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 Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=poly T3E mutant kn-keyword=poly T3E mutant en-keyword=type III effector kn-keyword=type III effector en-keyword=type III secretion system kn-keyword=type III secretion system END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=4 article-no= start-page=043024 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250428 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characterization of the thorium-229 defect structure in CaF2 crystals en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recent advancements in laser excitation of the low-energy thorium-229 (229Th) nuclear isomeric state in calcium fluoride (CaF2) single crystals render this system a promising candidate for a solid-state nuclear clock. Nonetheless, the precise experimental determination of the microscopic ion configuration surrounding the doped 229Th and its electronic charge state remains a critical challenge. Such characterization is essential for precisely controlling the clock transition and evaluating the performance of this solid-state nuclear clock system. In this study, we use x-ray absorption fine structure spectroscopy of 229Th:CaF2 to investigate the charge state and coordination environment of doped 229Th.

Although homologous recombination deficiency has been studied as a biomarker for other cancer types, the clinical and genomic implications of homologous recombination repair (HRR) gene mutations in SBA remain unclear.
Methods: We retrospectively analyzed the data of 628 patients with advanced or recurrent SBA from a nationwide genomic database. Patients were categorized into HRR mutation and non-HRR mutation groups and compared for their clinical and genomic characteristics including tumor mutational burden (TMB) and microsatellite instability-high (MSI-H) were compared. Treatment efficacy and overall survival (OS) were assessed based on HRR gene mutation status and primary tumor site (duodenal adenocarcinoma [DA] vs. small intestinal carcinoma [SIC]).
Results: Patients with the HRR mutations had higher frequencies of TMB and MSI-H than those without the mutation (P? Conclusion: HRR gene mutation may be a potential biomarker for platinum-based chemotherapy efficacy in SBA, especially in DA, highlighting the need for site-specific therapies. en-copyright= kn-copyright= en-aut-name=OzatoToshiki en-aut-sei=Ozato en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KonoYoshiyasu en-aut-sei=Kono en-aut-mei=Yoshiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HoriguchiShigeru en-aut-sei=Horiguchi en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsutsumiKoichiro en-aut-sei=Tsutsumi en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoHideki en-aut-sei=Yamamoto en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HirasawaAkira en-aut-sei=Hirasawa en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=TomidaShuta en-aut-sei=Tomida en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= 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, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Clinical Genomic Medicine, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Clinical Genomic Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Homologous recombination repair kn-keyword=Homologous recombination repair en-keyword=Small bowel adenocarcinoma kn-keyword=Small bowel adenocarcinoma en-keyword=Genome kn-keyword=Genome END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=2323 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A mini-hairpin shaped nascent peptide blocks translation termination by a distinct mechanism en-subtitle= kn-subtitle= en-abstract= kn-abstract=Protein synthesis by ribosomes produces functional proteins but also serves diverse regulatory functions, which depend on the coding amino acid sequences. Certain nascent peptides interact with the ribosome exit tunnel to arrest translation and modulate themselves or the expression of downstream genes. However, a comprehensive understanding of the mechanisms of such ribosome stalling and its regulation remains elusive. In this study, we systematically screen for unidentified ribosome arrest peptides through phenotypic evaluation, proteomics, and mass spectrometry analyses, leading to the discovery of the arrest peptides PepNL and NanCL in E. coli. Our cryo-EM study on PepNL reveals a distinct arrest mechanism, in which the N-terminus of PepNL folds back towards the tunnel entrance to prevent the catalytic GGQ motif of the release factor from accessing the peptidyl transferase center, causing translation arrest at the UGA stop codon. Furthermore, unlike sensory arrest peptides that require an arrest inducer, PepNL uses tryptophan as an arrest inhibitor, where Trp-tRNATrp reads through the stop codon. Our findings illuminate the mechanism and regulatory framework of nascent peptide-induced translation arrest, paving the way for exploring regulatory nascent peptides. en-copyright= kn-copyright= en-aut-name=AndoYushin en-aut-sei=Ando en-aut-mei=Yushin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KoboAkinao en-aut-sei=Kobo en-aut-mei=Akinao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NiwaTatsuya en-aut-sei=Niwa en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamakawaAyako en-aut-sei=Yamakawa en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KonomaSuzuna en-aut-sei=Konoma en-aut-mei=Suzuna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KobayashiYuki en-aut-sei=Kobayashi en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NurekiOsamu en-aut-sei=Nureki en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TaguchiHideki en-aut-sei=Taguchi en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ItohYuzuru en-aut-sei=Itoh en-aut-mei=Yuzuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ChadaniYuhei en-aut-sei=Chadani en-aut-mei=Yuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Biological Sciences, Graduate School of Science, The University of Tokyo kn-affil= affil-num=2 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=3 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=4 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=5 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=6 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=7 en-affil=Department of Biological Sciences, Graduate School of Science, The University of Tokyo kn-affil= affil-num=8 en-affil=School of Life Science and Technology, Institute of Science Tokyo kn-affil= affil-num=9 en-affil=Department of Biological Sciences, Graduate School of Science, The University of Tokyo kn-affil= affil-num=10 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=8 article-no= start-page=e70793 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250418 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genomic Differences and Distinct TP53 Mutation Site-Linked Chemosensitivity in Early- and Late-Onset Gastric Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Gastric cancer (GC) in younger patients often exhibits aggressive behavior and a poorer prognosis than that in older patients. Although the clinical differences may stem from oncogenic gene variations, it is unclear whether genetic differences exist between these groups. This study compared the genetic profiles of early- and late-onset GC and evaluated their impact on treatment outcomes.
Methods: We analyzed genetic data from 1284 patients with GC in the Japanese nationwide Center for Cancer Genomics and Advanced Therapeutics (C-CAT) database, comparing early-onset (<= 39 years; n = 143) and late-onset (>= 65 years; n = 1141) groups. The influence of TP53 mutations on the time to treatment failure (TTF) with platinum-based chemotherapy and the sensitivity of cancer cells with different TP53 mutation sites to oxaliplatin were assessed in vitro.
Results: Early- and late-onset GC showed distinct genetic profiles, with fewer neoantigen-associated genetic changes observed in early-onset cases. In particular, TP53 has distinct mutation sites; R175H and R273 mutations are more frequent in early- and late-onset GC, respectively. The R175H mutation showed higher sensitivity to oxaliplatin in vitro, consistent with the longer TTF in early-onset patients (17.3 vs. 7.0 months, p = 0.013) when focusing on the patients with TP53 mutations.
Conclusion: Genomic differences, particularly in TP53 mutation sites, between early- and late-onset GC support the need for age-specific treatment strategies. en-copyright= kn-copyright= en-aut-name=KamioTomohiro en-aut-sei=Kamio en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KonoYoshiyasu en-aut-sei=Kono en-aut-mei=Yoshiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HirosunaKensuke en-aut-sei=Hirosuna en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OzatoToshiki en-aut-sei=Ozato en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoHideki en-aut-sei=Yamamoto en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HirasawaAkira en-aut-sei=Hirasawa en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=TomidaShuta en-aut-sei=Tomida en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= 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, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Regenerative Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Clinical Genomic Medicine, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Clinical Genomic Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=comprehensive genomic profiling kn-keyword=comprehensive genomic profiling en-keyword=early-onset gastric cancer kn-keyword=early-onset gastric cancer en-keyword=oxaliplatin kn-keyword=oxaliplatin en-keyword=TP53 kn-keyword=TP53 END start-ver=1.4 cd-journal=joma no-vol=43 cd-vols= no-issue=6 article-no= start-page=1108 end-page=1116 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Spray-drying of polymer solutions across a broad concentration range and the subsequent formation of a few micro- ?nano-meter sized fibers en-subtitle= kn-subtitle= en-abstract= kn-abstract=Spray drying is a widely utilized technique for the concentration and fine particulation of dried products. This study demonstrated that a versatile spray dryer, equipped with a two-fluid nozzle atomizer, can convert polymer solutions into nanoscale fibers by manipulating the conditions of the polymer solutions. The polymers employed in this research included polyvinylpyrrolidones (Mw 24.5 k to 60?kDa), dextrans (70 k to 450?650?kDa), pullulan, gum Arabic, Eudragit and agar, with methanol and water serving as solvents. Various combinations of polymers and solvents were subjected to spray drying at polymer concentrations ranging from 5 to 1000?g/L. Scanning electron microscopy analyses of the spray-dried samples indicated that the products transitioned from micrometer-sized particles to sub-micrometer fibers in several instances when the polymer concentrations exceeded specific threshold levels. The investigation also explored the relationship between these threshold concentrations and the surface tension and viscosity of the polymer solutions. en-copyright= kn-copyright= en-aut-name=AragaChika en-aut-sei=Araga en-aut-mei=Chika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukushimaKaito en-aut-sei=Fukushima en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoHaruna en-aut-sei=Sato en-aut-mei=Haruna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HondaNao en-aut-sei=Honda en-aut-mei=Nao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HasegawaTakato en-aut-sei=Hasegawa en-aut-mei=Takato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakasoKoichi en-aut-sei=Nakaso en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IshidaNaoyuki en-aut-sei=Ishida en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ImamuraKoreyoshi en-aut-sei=Imamura en-aut-mei=Koreyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Department of Chemical Engineering and Material Sciences, Faculty of Science and Engineering, Doshisha University kn-affil= affil-num=8 en-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Sub-micron fiber kn-keyword=Sub-micron fiber en-keyword=spray-drying kn-keyword=spray-drying en-keyword=two fluid nozzle atomizer kn-keyword=two fluid nozzle atomizer en-keyword=polyvinylpyrrolidone kn-keyword=polyvinylpyrrolidone en-keyword=polysaccharide kn-keyword=polysaccharide END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=93 end-page=100 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lower Work Engagement Is Associated with Insomnia, Psychological Distress, and Neck Pain among Junior and Senior High School Teachers in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=School teachers are subject to both physical and mental health problems. We examined cross-sectional relationships between work engagement and major health outcomes among junior and senior high school teachers in Japan via a nationwide survey in 2019-2020. A total of 3,160 respondents were included in the analyses (19.9% response rate). Work engagement was assessed with the Utrecht Work Engagement Scale-9 (UWES-9), and we thus divided the teachers into quartiles according to their UWES-9 scores. Based on validated questionnaires, we assessed insomnia, psychological distress, and neck pain as health outcomes. A binomial logistic regression adjusted for age, gender, school type, teacher’s roles, involvement in club activities, division of duties, employment status, and whether they lived with family demonstrated that the teachers with lower UWES-9 scores had higher burdens of insomnia, psychological distress, and neck pain (odds ratios [95% confidence intervals] in 4th vs. 1st quartile, 2.92 (2.34-3.65), 3.70 (2.81-4.88), and 2.12 (1.68-2.68), respectively; all trend p<0.001). There were no significant differences in these associations between full-time and part-time teachers. Our findings indicate that low work engagement may contribute to physical and mental health issues among junior and senior high school teachers, thus providing insights for preventing health problems in this profession. en-copyright= kn-copyright= en-aut-name=TsuchieRina en-aut-sei=Tsuchie en-aut-mei=Rina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukudaMari en-aut-sei=Fukuda en-aut-mei=Mari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsumuraHideki en-aut-sei=Tsumura en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KinutaMinako en-aut-sei=Kinuta en-aut-mei=Minako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HisamatsuTakashi en-aut-sei=Hisamatsu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KandaHideyuki en-aut-sei=Kanda en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Psychology, Graduate School of Technology, Industrial and Social Sciences, Tokushima University kn-affil= affil-num=4 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=work engagement kn-keyword=work engagement en-keyword=school teachers kn-keyword=school teachers en-keyword=insomnia kn-keyword=insomnia en-keyword=psychological distress kn-keyword=psychological distress en-keyword=neck pain kn-keyword=neck pain END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=7 article-no= start-page=2221 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Length Estimation of Pneumatic Artificial Muscle with Optical Fiber Sensor Using Machine Learning en-subtitle= kn-subtitle= en-abstract= kn-abstract=A McKibben artificial muscle is a soft actuator driven by air pressure, characterized by its flexibility, lightweight design, and high power-to-weight ratio. We have developed a smart artificial muscle that is capable of sensing its motion. To enable this sensing function, an optical fiber was integrated into the sleeve consisting of multiple fibers and serving as a component of the McKibben artificial muscle. By measuring the macrobending loss of the optical fiber, the length of the smart artificial muscle is expected to be estimated. However, experimental results indicated that the sensor's characteristics depend not only on the length but also on the load and the applied air pressure. This dependency arises because the stress applied to the optical fiber increases, causing microbending loss. In this study, we employed a machine learning model, primarily composed of Long Short-Term Memory (LSTM) neural networks, to estimate the length of the smart artificial muscle. The experimental results demonstrate that the length estimation obtained through machine learning exhibits a smaller error. This suggests that machine learning is a feasible approach to enhancing the length measurement accuracy of the smart artificial muscle. en-copyright= kn-copyright= en-aut-name=NiYilei en-aut-sei=Ni en-aut-mei=Yilei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WakimotoShuichi en-aut-sei=Wakimoto en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TianWeihang en-aut-sei=Tian en-aut-mei=Weihang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TodaYuichiro en-aut-sei=Toda en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KandaTakefumi en-aut-sei=Kanda en-aut-mei=Takefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamaguchiDaisuke en-aut-sei=Yamaguchi 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 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= en-keyword=McKibben artificial muscle kn-keyword=McKibben artificial muscle en-keyword=machine learning kn-keyword=machine learning en-keyword=optical fiber kn-keyword=optical fiber en-keyword=motion estimation kn-keyword=motion estimation END start-ver=1.4 cd-journal=joma no-vol=2024 cd-vols= no-issue=12 article-no= start-page=135 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241217 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Elliptic virtual structure constants and generalizations of BCOV-Zinger formula to projective Fano hypersurfaces en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this paper, we propose a method for computing genus 1 Gromov-Witten invariants of Calabi-Yau and Fano projective hypersurfaces using the B-model.

The x-ray absorption method is an effective method to measure the density of non-crystalline materials at high pressures. However, the temperature condition of the x-ray absorption method using a diamond anvil cell (DAC) has been limited to 720 K to date. To significantly expand the measurable temperature condition of this method, in this study, we developed a density measurement technique using the x-ray absorption method in combination with a laser-heated DAC. The density of solid Ni was measured up to 26 GPa and 1800 K using the x-ray absorption method and evaluated by comparison with the density obtained from the x-ray diffraction. The density of solid Ni with a thickness >17 μm was determined with an accuracy of 0.01%?2.2% (0.001?0.20 g/cm3) and a precision of 0.8%?1.8% (0.07?0.16 g/cm3) in the x-ray absorption method. The density of liquid Ni was also determined to be 8.70 ± 0.15?8.98 ± 0.38 g/cm3 at 16?23 GPa and 2230?2480 K. Consequently, the temperature limit of the x-ray absorption method can be expanded from 720 to 2480 K by combining it with a laser-heated DAC in this study. en-copyright= kn-copyright= en-aut-name=TerasakiHidenori en-aut-sei=Terasaki en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KaminaHiroyuki en-aut-sei=Kamina en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawaguchiSaori I. en-aut-sei=Kawaguchi en-aut-mei=Saori I. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KondoTadashi en-aut-sei=Kondo en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MoriokaKo en-aut-sei=Morioka en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsuruokaRyo en-aut-sei=Tsuruoka en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakuraiMoe en-aut-sei=Sakurai en-aut-mei=Moe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YonedaAkira en-aut-sei=Yoneda en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KamadaSeiji en-aut-sei=Kamada en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HiraoNaohisa en-aut-sei=Hirao en-aut-mei=Naohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=3 en-affil=Japan Synchrotron Radiation Research Institute, SPring-8 kn-affil= affil-num=4 en-affil=Department of Earth and Space Science, Osaka University kn-affil= affil-num=5 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Earth and Space Science, Osaka University kn-affil= affil-num=7 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Earth and Space Science, Osaka University kn-affil= affil-num=9 en-affil=AD Science Incorporation kn-affil= affil-num=10 en-affil=Japan Synchrotron Radiation Research Institute, SPring-8 kn-affil= END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=6 article-no= start-page=2485 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250311 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Vesicular Glutamate Transporter 3 Is Involved in Glutamatergic Signalling in Podocytes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Glomerular podocytes act as a part of the filtration barrier in the kidney. The activity of this filter is regulated by ionotropic and metabotropic glutamate receptors. Adjacent podocytes can potentially release glutamate into the intercellular space; however, little is known about how podocytes release glutamate. Here, we demonstrated vesicular glutamate transporter 3 (VGLUT3)-dependent glutamate release from podocytes. Immunofluorescence analysis revealed that rat glomerular podocytes and an immortal mouse podocyte cell line (MPC) express VGLUT1 and VGLUT3. Consistent with this finding, quantitative RT-PCR revealed the expression of VGLUT1 and VGLUT3 mRNA in undifferentiated and differentiated MPCs. In addition, the exocytotic proteins vesicle-associated membrane protein 2, synapsin 1, and synaptophysin 1 were present in punctate patterns and colocalized with VGLUT3 in MPCs. Interestingly, approximately 30% of VGLUT3 colocalized with VGLUT1. By immunoelectron microscopy, VGLUT3 was often observed around clear vesicle-like structures in differentiated MPCs. Differentiated MPCs released glutamate following depolarization with high potassium levels and after stimulation with the muscarinic agonist pilocarpine. The depletion of VGLUT3 in MPCs by RNA interference reduced depolarization-dependent glutamate release. These results strongly suggest that VGLUT3 is involved in glutamatergic signalling in podocytes and may be a new drug target for various kidney diseases. en-copyright= kn-copyright=

en-title=Daily Social Support among Canberra Residents kn-title=日常生活における援助希求行動 ―キャンベラの事例― en-subtitle= kn-subtitle= en-abstract= kn-abstract=　This paper reports a study that investigated perceived sources of daily support. To gather empirical evidence, a sample survey of women in four study areas of Canberra was conducted in 1986-1987. Three hundred and ninety-four women who were under 55 years of age and who were married or in a de facto relationship were interviewed. They responded to six hypothetical difficult situations by identifying the first source from which they would seek support. Analysis of the data has revealed the following ;
　(1) When respondents had their relatives in Canberra, they regarded their relatives as the chief source of daily support. However, there were many residents without local relatives in Canberra. For such respondents, their relatives were not so helpful in daily support. Incidentally, workmates were thought of as much less important providers of support than relatives, neighbours or friends.
　(2) Social networks were differentiated in that respondents tended to depend on types of people appropriate to individual difficult situations.
　(3) Dependable friends and workmates tended to live closer than dependable relatives.
　(4) Dependable relatives were usually limited to immediate family, such as parents (-in-law), brothers (-in-law) or sisters (-in-law). en-copyright= kn-copyright= en-aut-name=NOBEMASAO

2時限連続の授業を設けることができるようにするなど，授業の性格に応じてより柔軟に，授業を開講できるようすべきだ。もしこれが可能であれば，私の授業に対する学生の苦情はほとんどなかった。第2に，シラバスを全学部の学生に配布するとか，インターネットで誰でも簡単に閲覧できるようにすべきだ。
　次に，授業の改善として，私は次の3点を提案した。(1)研究の方法を一般教育課程で学生に組織的に教えること。(2)大学の授業を他の教官に公開することによって，授業の改善に努めること。(3)教官の授業負担を軽減し，授業の充実をはかること。 en-copyright= kn-copyright= en-aut-name=NOBEMasao en-aut-sei=NOBE

とくに悪い点は指摘されなかった。その結果，学生は86.2点と比較的高めに私の授業を採点した。(2)書評レポートを学生に課すとき，その見本を学生に配布すると，書評レポートの質が大幅に向上する。(3)学生は私の授業を好意的にとらえていたけれど，受講学生数は少なかった。これから，受講学生数は主に授業の単位取得が容易かどうかによって決まってしまうと考えられる。 en-copyright=

Prince Jisshin kn-title=稲盛和夫のフィロソフィーと西郷南洲翁遺訓及び日新公いろは歌の連関についての考察 en-subtitle= kn-subtitle= en-abstract=Kazuo Inamori is a rare business leader who founded DDI, the predecessor of Kyocera and KDDI, in one generation, and grew it into a trillion-yen company. He also rebuilt the bankrupt Japan Airlines (JAL) in three years and led it to relisting. He has not only led tens of thousands of people with his unique management method called amoeba management, but also with management principles. What are the roots of the way of life that a manager of a small and medium-sized business has derived from management? What is the Goju education that is the foundation of Satsuma, where he was born and raised? From the perspective of business management, it is interesting to know what it is like.
How is it related to Saigo Nanshu Ikun, the record of the words and deeds of Saigo Takamori, a local hero whom Kazuo Inamori met after founding Kyocera and used as the basis of his own management philosophy, and Shimazu Nisshin Iroha Uta, left by Shimazu Tadayoshi (Nissin), the father of Shimazu Takahisa, the 15th lord of the Shimazu clan who unified southern Kyushu, including Satsuma and Hyuga, in the 16th century? First of all, I am interested in the relationship between the ideas of the three men born in Satsuma. In this study, we used the grounded theory approach, a qualitative research method, to analyze the correlation between Kazuo Inamori's philosophy, the teachings of Nanshu Saigo, and the Nisshin Iroha Uta. As a result, the analysis revealed that the three concepts are related across 400 years of time. In particular, Kazuo Inamori's philosophy is not only positively influenced by the teachings of Nanshu Saigo, which are the words and deeds of Takamori Saigo, whom Kazuo Inamori admires, but also by the Nisshin Iroha Uta, which dates back 400 years, due to his education in Satsuma. It is believed that the ideals that the people of Satsuma have inherited for 400 years contain concepts that should be the foundation for people's lives, or that should be important core ideas and qualities in life, regardless of the era. kn-abstract=　一代で京セラやKDDIの前身となる第二電電（DDI）を創業し、合計数兆円企業に育て、倒産した日本航空（JAL）を3年で再建し、再上場に導いた稀代の経営者稲盛和夫は、アメーバ経営という独自の経営手法だけでなく、理念経営により数万人を導いてきた。中小企業の一経営者が経営の中から導き出した人生成功の処世術のルーツは何処にあるのか。生まれ育った薩摩の基礎となる郷中（ごじゅう）教育とは何か、などについて経営学の観点から関心が湧く。
　稲盛和夫が京セラ創業以降に出会い、自ら経営理念の基礎とした地元の偉人である西郷隆盛の言行録である西郷南洲翁遺訓及び16世紀に薩摩や日向など南九州を統一した島津家第15代領主島津貴久公の実父島津忠良（日新）が残した、島津日新公いろは歌とどのように連関があるのか。そもそも薩摩生まれの3名の思想にどのような連関があるのか、についても関心が湧く。この研究では、質的研究法であるグラウンデッド・セオリー・アプローチを援用して、稲盛和夫のフィロソフィーと西郷南洲翁遺訓及び日新公いろは歌の連関について分析した。結果的に3つの概念は400年の時代を超えて、連関していることが分析により明らかになった。特に稲盛和夫のフィロソフィーが稲盛和夫が敬愛する西郷隆盛の言行録である西郷南洲翁遺訓に正の影響を受けているだけでなく、薩摩での教育を背景に、400年前に遡る日新公いろは歌からも正の影響を受けていることが明らかになった。400年に渡り薩摩の人々が受け継いできた理念には、時代を超えても人が生きていく中で基礎とすべき、もしくは人生で重要なコアな思想・資質とすべき概念があると考えられる。

study is to examine the impact of school mergers and closures on children through a literature review and field survey and to propose strategies for supporting children's adaptation to the resulting environmental transitions. First, a literature review on school mergers and closures indicated that such experiences could influence children's later interpersonal relationships and increase stress responses. However, research on the impact of school mergers and closures on children remains limited, with insufficient understanding of their psychological effects on children. Next, interviews conducted as part of a field survey revealed that school mergers and closures could be significant sources of stress for children. Based on these findings, we recommends multi-level support measures targeting individuals, classes, grades, and entire schools, primarily through special activities, to help mitigate the impact of these transitions on children. kn-abstract=本研究の目的は，学校統廃合に係る文献検索および実態調査を通して，学校統廃合という環境移行が児童に与える影響について検討し，学校統廃合がもたらす環境移行に対する児童の適応支援策について提言することである。まず，学校統廃合に係る文献検索を行った結果，学校統廃合の経験が児童生徒のその後の人間関係形成やストレス反応の増加に影響を与えている可能性が示された。しかし，学校統廃合が児童に与える影響に関する研究は非常に少なく，統廃合の経験が児童に与える心理的影響については十分に解明されていないことがわかった。次に，実態調査として行ったインタビューにおいて，学校統廃合が児童にとって大きなストレス要因となる可能性があることがわかった。これらの現状を踏まえて，学校統廃合が児童に与える影響を和らげるため，特別活動を中心として，個人・学級・学年・学校レベルでの具体的な取組を提案した。 en-copyright= kn-copyright= en-aut-name=IKEDAYuka en-aut-sei=IKEDA en-aut-mei=Yuka kn-aut-name=池田?加 kn-aut-sei=池田 kn-aut-mei=?加 aut-affil-num=1 ORCID= en-aut-name=IZUMITsuguyuki en-aut-sei=IZUMI en-aut-mei=Tsuguyuki kn-aut-name=伊住継行 kn-aut-sei=伊住 kn-aut-mei=継行 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education (Professional Degree Corse), Okayama University kn-affil=岡山大学大学院教育学研究科大学院生 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=学校統廃合 (School Consolidation) kn-keyword=学校統廃合 (School Consolidation) en-keyword=児童 (Children) kn-keyword=児童 (Children) en-keyword=人間関係形成 (Relationship Building) kn-keyword=人間関係形成 (Relationship Building) en-keyword=ストレス (Stress) kn-keyword=ストレス (Stress) en-keyword=特別活動 (Special Activities) kn-keyword=特別活動 (Special Activities) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=341 end-page=355 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Research Trends on Educational Needs and Support of Children with Cancer kn-title=小児がん患児に対する教育的支援とその研究動向 en-subtitle= kn-subtitle= en-abstract=　In this study, we summarized research trends related to the educational needs and support of children with cancer from the perspectives of “learning,” “self-management,” “interpersonal,” “psychological,” and “collaboration,”. In terms of learning, the study showed that experiential learning and distance education are solutions to the problem of delayed learning due to prolonged absence from school and poor concentration during treatment. Next, in self-management, it is important to educate affected children so that they can fully understand the disease and treatment. In addition, in terms of interpersonal support, it is difficult for the affected patients to build relationships with friends, but providing opportunities for interaction is expected to contribute to the improvement of interpersonal relationships. In terms of psychological support, the anxiety associated with treatment is a major psychological burden for the affected children, and the understanding of their friends and the intervention of university student volunteers are effective in helping them achieve psychological stability. Finally, the lack of cooperation between medical institutions and schools was highlighted as a deficiency in the support system, which needs to be strengthened. In the future, these support measures should be empirically verified to establish a sustainable support system. kn-abstract=　本研究は、小児がん患児の教育的支援に関する研究の動向を明らかにし、今後の課題とその解決策を提起することを目的とした。「学習」、「自己管理」、「対人」、「心理」、「連携」の5つの視点から分析を行った。学習支援について、治療に伴う学習の遅れや集中力の低下に対し、個別の教育支援計画や体験的な学習、および遠隔教育の実施に期待されていた。自己管理支援では、患児が自身の病状や治療による副作用を理解し、自立的に管理できる能力を育成することが求められていた。対人支援について、患児の長期入院により、友人関係の構築が困難になり、入院中や復学後のコミュニケーションの支援が重要であることが確認された。心理支援においては、周囲への効果的ながん教育や大学生ボランティアによる支援が、患児の心理的安定を促すことが示された。最後に、学校と医療機関、保護者の連携不足が指摘されており、連携ツールの開発が求められている。 en-copyright= kn-copyright= en-aut-name=CHENYiwen en-aut-sei=CHEN en-aut-mei=Yiwen kn-aut-name=陳依文 kn-aut-sei=陳 kn-aut-mei=依文 aut-affil-num=1 ORCID= en-aut-name=YOSHITOSHIMunehisa en-aut-sei=YOSHITOSHI en-aut-mei=Munehisa kn-aut-name=吉利宗久 kn-aut-sei=吉利 kn-aut-mei=宗久 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education Doctoral Programs, Hyogo University of Teacher Education kn-affil=兵庫教育大学大学院連合学校教育学研究科博士課程 affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=小児がん (child hood cancer) kn-keyword=小児がん (child hood cancer) en-keyword=慢性疾患 (chronic illness) kn-keyword=慢性疾患 (chronic illness) en-keyword=教育的ニーズ (educational needs) kn-keyword=教育的ニーズ (educational needs) en-keyword=研究動向 (research trends) kn-keyword=研究動向 (research trends) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=325 end-page=339 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Recommendations on how to View STEAM Education in General Education and Development of Classes and Teacher Training ?Through the Enrichment of Integrated Inquiry Time? kn-title=普通科における STEAM 教育の捉え方の提言と授業および教員研修の開発　―総合的な探究の時間の充実を通して― en-subtitle= kn-subtitle= en-abstract= kn-abstract=　本実践報告では，普通科における STEAM 教育の捉え方を提言し，具体的な授業実践や教員研修を提案する。先行研究等で議論されている STEAM 教育の概念等から，STEAM 教育の根幹は創造性を涵養・刺激・発揮する教育であると捉え，STEAM 教育と最も親和性が高い総合的な探究の時間で授業実践を行った。取り組みの効果については，成果物の分析やヒアリング調査等を通して検証し，探究を自分事にできていることが示唆された。また，生徒が創造性を涵養・刺激・発揮する場面は，各教科等の授業内でも実現できると考え，「楽しく深まる授業」をテーマにした教員研修の開発を行った。この研修では授業開発を教員のチーム探究と捉え，総合的な探究の時間で生徒が取り組むワーク等も活用した。総合的な探究の時間を受けた経験のない教員が探究活動のプロセスを経験し，探究の楽しさやワクワク感を実感できることも狙っている。主体的で活発な全校研修が実現し，教員が探究的に授業創りを進めることのできる研修の仕掛けを見出すことができた。 en-copyright= kn-copyright= en-aut-name=EBARAMitsuo en-aut-sei=EBARA en-aut-mei=Mitsuo kn-aut-name=江原光夫 kn-aut-sei=江原 kn-aut-mei=光夫 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=Okayama Prefectural Kurashiki Amaki High School (Graduate School of Education (Professional Degree Corse), Okayama University) kn-affil=岡山大学大学院教育学研究科大学院生 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=STEAM 教育 (STEAM education) kn-keyword=STEAM 教育 (STEAM education) en-keyword=創造性 (creativity) kn-keyword=創造性 (creativity) en-keyword=総合的な探究の時間 (integrated inquiry time) kn-keyword=総合的な探究の時間 (integrated inquiry time) en-keyword=普通科 (general education) kn-keyword=普通科 (general education) en-keyword=教員研修 (teacher training) kn-keyword=教員研修 (teacher training) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=313 end-page=324 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=An Attempt at International Understanding Education Incorporating Letter Exchange Activities between Japanese and Chinese High School Students: Through Development of a Civics Unit Plan on International Issues kn-title=日中の高校生の手紙を使った交流活動を取り入れた国際理解教育の試み　―国際的課題を取り上げた公民科の単元開発― en-subtitle= kn-subtitle= en-abstract=This study reports the results of the development and practice of a class in which Japanese and Chinese high school students deepened mutual understanding and became aware of themselves as members of the international community through l earning activities in which they exchanged letters in order to share their thoughts on a global international issue.

In other words, learning is not confined to the classroom but is reinforced through a wide range of activities. This study aimed to nurture “autonomous and self-directed learning” among students in the second grade at a public junior high school by integrating classroom and home learning. Teachers emphasized the importance of learning strategies and goal setting, and encouraged metacognition. As a result, students became more aware of the self-regulated learning cycle and began exploring learning strategies tailored to their needs. In addition, working at home on assignments connected to the class not only increased students’ active participation in class but also improved their motivation to learn independ ently outside of class. kn-abstract=　生徒が自ら学習を進めていく力を身に付けるには，授業内だけでなく，家庭など授業外の場での学習経験を積む必要がある。つまり，学習は授業内だけで完結するのではなく，広範な活動を通して成立する。本研究では，公立中学校の第2学年を対象に授業と家庭学習を連携させる実践を行い，生徒の「主体的・自律的な学び」を萌芽させることを目指した。教師が学習方略や目標設定の重要性を伝え，メタ認知を促すことで，生徒は自己調整学習のサイクルを意識し，自分なりの学習方略を探求するようになった。また，家庭学習で授業につながる課題に取り組むことで，授業への主体的な参加と，授業外で自律的に学ぶ意欲が促されることも示唆された。 en-copyright= kn-copyright= en-aut-name=TANAKAJunko en-aut-sei=TANAKA en-aut-mei=Junko kn-aut-name=田中純子 kn-aut-sei=田中 kn-aut-mei=純子 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= affil-num=1 en-affil=Okayama Municipal Hosen Junior High School kn-affil=岡山市立芳泉中学校 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=授業と家庭学習の連携 (coordination between classroom and home learning) kn-keyword=授業と家庭学習の連携 (coordination between classroom and home learning) en-keyword=自己調整学習 (self-regulated learning) kn-keyword=自己調整学習 (self-regulated learning) en-keyword=宿題 (homework) kn-keyword=宿題 (homework) en-keyword=授業改善 (lesson improvement) kn-keyword=授業改善 (lesson improvement) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=281 end-page=295 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Development Support a Child with Autism to Acquisition of Intersubjective Communication: Through the Environmental Setting of Play with Shared Positive Emotions kn-title=ASD 児における相互伝達行為の獲得を目指した遊びを中心としたコミュニケーション指導　ポジティブな情動の共有を生み出す遊びの環境設定を通して en-subtitle= kn-subtitle= en-abstract=In this study, a play-based instruction was used to promote the acquisition of intersubjective communication in a special needs school for students with intellectual disabilities.

Therefore, this study aimed to examine the prevention of apathy among high school students. Apathy among college students has been examined as a propensity for apathy. This study presupposes that apathy among high school students is also associated with a propensity for apathy. Two hundred and nineteen high school students were participated in this research. We assumed time management (TM) and future prospects (self-fulfillment, goal-directedness, and hopefulness) would be preventive factors against apathetic tendencies for them. The study findings indicate that self-fulfillment may significantly reduce apathy, with hopefulness also contributing to reducing apathy. Additionally, the characteristics of apathy tendency, specifically lack of self, were found to be differently related to students' TM skills. In other words, the findings suggest that goal-directedness may alleviate apathy among students struggling with TM. kn-abstract=　不登校の主たる要因の1位は「無気力・不安」で40.0%を占める（文部科学省，2023）。このことは，不登校でない生徒の中にも，無気力を感じている生徒がかなりいることを示唆している。そこで本研究は，高校生の無気力とその予防について検討する。無気力は，大学生を対象にアパシー傾向として検討されてきた。そこで高校生の無気力をアパシー傾向として捉え，加えてそれを予防するものについても併せて検討した。予防法の候補として，タイムマネジメント（以下，TM）と将来展望（現在の充実感・目標指向性・希望）を想定し，高校生219名を対象に，これらの関係を検討した。分析の結果，無気力を低減するのは，現在の充実感，希望であり，特に前者が有効である可能性を示せた。一方で，アパシー傾向の自分のなさでは，TM のタイプによって異なる関係がみられた。つまり，TM が苦手な生徒では，希望よりも，目前の目標に目を向けることが無気力を低減できる可能性が示唆された。 en-copyright= kn-copyright= en-aut-name=ASADAAsuka en-aut-sei=ASADA en-aut-mei=Asuka kn-aut-name=麻田明日香 kn-aut-sei=麻田 kn-aut-mei=明日香 aut-affil-num=1 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=2 ORCID= affil-num=1 en-affil=KANKO GAKUSEIFUKU CO., LTD. kn-affil=菅公学生服 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　教授 en-keyword=高校生 (High School Students) kn-keyword=高校生 (High School Students) en-keyword=無気力 kn-keyword=無気力 en-keyword=アパシー傾向 (Apathy tendency) kn-keyword=アパシー傾向 (Apathy tendency) en-keyword=タイムマネジメント (Time Management) kn-keyword=タイムマネジメント (Time Management) en-keyword=将来展望 (Future Prospect) kn-keyword=将来展望 (Future Prospect) en-keyword=Prevention kn-keyword=Prevention END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=179 end-page=190 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Current Trends and Future Issues Related to Song’s speed in the Preschool-Elementary Cooperated Education Research kn-title=幼児歌唱曲の速度感の傾向と課題 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　本研究では，音楽教育的観点から幼児歌唱曲の選定のあり方を検討した。その際，小学校の音楽教育で歌唱共通課題として挙げられてきた教材を比較対象とし，その傾向と課題を考察する。１つ目は曲の速度感において歌唱共通教材と選定頻度の高い幼児歌唱曲の平均的な速度において，どの程度の差があるのかという調査を行った。２つ目は，幼稚園と小学校音楽科で共通して用いられる教材曲の作曲された年代の違いについて明らかにした。この２つの調査を用いて，歌唱共通課題に選定されている曲の速度感から現代の子どもの歌の速度感の傾向を明らかにした。この結果から幼稚園教育における幼児歌唱曲のチャートを作成することによって，伝統的に歌い継がれてきた幼児歌唱曲の再考の可能性を示した。 en-copyright= kn-copyright= en-aut-name=TAKASUHiromi en-aut-sei=TAKASU en-aut-mei=Hiromi kn-aut-name=須裕美 kn-aut-sei=須 kn-aut-mei=裕美 aut-affil-num=1 ORCID= affil-num=1 en-affil=Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=幼保小連携 (Preschool-elementary cooperation) kn-keyword=幼保小連携 (Preschool-elementary cooperation) en-keyword=子供の歌の速度感 (Children’s Song speed) kn-keyword=子供の歌の速度感 (Children’s Song speed) en-keyword=子供の歌文化 (Children’s singing culture) kn-keyword=子供の歌文化 (Children’s singing culture) en-keyword=伝統音楽 (Japanese traditional song materials) kn-keyword=伝統音楽 (Japanese traditional song materials) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=163 end-page=177 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Climate and Songs of Spring/May Around Germany (Part U): A Report of an Interdisciplinary Lesson Practice at the University Leading to the Understanding of Heterogeneous Others kn-title=ドイツ付近の春・５月の気候と歌（その２）：異質な他者への出会いを促す大学での学際的授業の実践 en-subtitle= kn-subtitle= en-abstract=An interdisciplinary lesson practice for the university students leading to the understanding of heterogeneous others was made on a topic of climate and songs of "spring/May" around Germany, as a continuing study of Kato et al.

Then, several German lieder, a film music, etc. were appreciated, paying attention to the relation between expressions of the songs and their climate backgrounds.

The methodology involved conducting interviews with four experienced teachers from School A, a special needs school for students with intellectual disabilities, which had successfully navigated difficult periods due to challenges in student guidance. Qualitative analysis was conducted using the Modified Grounded Theory Approach (M-GTA). As a result, two core categories emerged: "Building relationships with individuals that foster a sense of security" and "Aiming for shared and unified approaches." Sixteen concepts were generated. When faced with behavioral problems, teachers focused on "Building relationships with individuals that foster a sense of security" as the axis for responding to students, while behind the scenes the teachers worked collectively toward "Aiming for shared and unified approaches." Finally, based on the framework clarified in this study, a hierarchical, comprehensive support system, including individualized support, was proposed. kn-abstract=　本研究の目的は，知的障害特別支援学校高等部に在籍する生徒の行動問題に着目し，学校現場で教員が適切に対応する際の枠組みを明らかにすることである。その方法として，生徒指導上の課題を理由とする教育困難期を乗り越えたA 知的障害特別支援学校高等部に所属していた経験豊富な教員4名に面接調査を実施し，M-GTA の手法を援用した質的分析を行った。その結果，【安心感を生む個との関係づくり】と【対応方法の共有と統一化を目指す】関係性がコア・カテゴリーと位置づき，16の諸概念を生成した。行動問題に直面した教員は，生徒に対しては【安心感を生む個との関係づくり】を対応の軸とし，その背後では学校として【対応方法の共有と統一化を目指す】ための動きをしていた。最後に，本研究で明らかとなった対応の枠組みについて考察した観点から，個別の時間を含む階層性のある包括的な支援システムを一つの提案とした。 en-copyright= kn-copyright= en-aut-name=TOKIMITSUHideaki en-aut-sei=TOKIMITSU en-aut-mei=Hideaki kn-aut-name=時光秀明 kn-aut-sei=時光 kn-aut-mei=秀明 aut-affil-num=1 ORCID= en-aut-name=MIYAZAKIYoshio en-aut-sei=MIYAZAKI en-aut-mei=Yoshio kn-aut-name=宮ｱ善郎 kn-aut-sei=宮ｱ kn-aut-mei=善郎 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education (Professional Degree Course), Okayama University kn-affil=岡山大学大学院教育学研究科大学院生 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=高等部 (High school division) kn-keyword=高等部 (High school division) en-keyword=軽度知的障害 (Mild intellectual disabilities) kn-keyword=軽度知的障害 (Mild intellectual disabilities) en-keyword=発達障害 (Developmental disorders) kn-keyword=発達障害 (Developmental disorders) en-keyword=行動問題 (Behavioral problems) kn-keyword=行動問題 (Behavioral problems) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=133 end-page=145 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The Image of Mushroom Created by Junior High School Science Textbooks: Suggestions for Learning about Mushroom from Diachronic Surveys kn-title=中学校理科教科書がつくり上げてきたきのこ像　―通時的調査から得るきのこを巡る学習への示唆― en-subtitle= kn-subtitle= en-abstract=　In this paper, we examined the image of mushroom in postwar junior high school science textbooks from four perspectives: (1) which species of mushroom were covered, (2) whether they were classified as plants or not, (3) what makes up the body of a mushroom, and (4) how they functioned in an ecosystem. The 47 species were identified through a periodic survey. Although a total of 47 species have appeared in science textbooks, we pointed out that in recent years, the focus has shifted to the role of mushroom as decomposers, rather than to species awareness. We also pointed out that although mycorrhizal fungi have been discussed in textbooks, there was no reference to the perspective in a plant-fungal symbiosis, which raises the possibility of developing learning that aims to understand symbiosis/interactions within a nature ecosystem. kn-abstract=　本稿では，戦後中学校理科検定教科書におけるきのこの扱われ方，すなわち学習者が受け取ることになるきのこ像について，@どのようなきのこが扱われてきたのか，A植物に分類されているか否か，Bきのこのからだは何で形成されているのか，C生態系における働きの四つの観点から，通時的な調査によって明らかにした。全47種がこれまでの理科教科書で登場してきたが，近年は種への意識というよりも，きのこが分解者としての役割を持つことにのみ焦点が当てられてきていることを指摘した。また，これまで教科書においては菌根性のきのこ自体について取り上げられつつも，その生態系における相利共生の観点への言及はないことから，相利共生の理解を目指す学習の開発が可能性として浮かび上がってくることも指摘した。 en-copyright= kn-copyright= en-aut-name=TAKAGIRisa en-aut-sei=TAKAGI en-aut-mei=Risa kn-aut-name=木里彩 kn-aut-sei=木 kn-aut-mei=里彩 aut-affil-num=1 ORCID= en-aut-name=IKEDAMasafumi en-aut-sei=IKEDA en-aut-mei=Masafumi kn-aut-name=池田匡史 kn-aut-sei=池田 kn-aut-mei=匡史 aut-affil-num=2 ORCID= en-aut-name=YAMAMOTOMasaya en-aut-sei=YAMAMOTO en-aut-mei=Masaya kn-aut-name=山本将也 kn-aut-sei=山本 kn-aut-mei=将也 aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Education (Professional Degree Corse), Okayama University kn-affil=岡山大学大学院教育学研究科大学院生 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=3 en-affil=Hyogo University of Teacher Education kn-affil=兵庫教育大学大学院学校教育研究科 en-keyword=菌類 (Fungus) kn-keyword=菌類 (Fungus) en-keyword=菌根菌 (Mycorrhizal Fungi) kn-keyword=菌根菌 (Mycorrhizal Fungi) en-keyword=腐生菌 (Saprobic Fungi) kn-keyword=腐生菌 (Saprobic Fungi) en-keyword=相利共生 (Symbiosis) kn-keyword=相利共生 (Symbiosis) en-keyword=教材史 (History of teaching materials) kn-keyword=教材史 (History of teaching materials) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=119 end-page=132 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The Development of Thoughts on the Effective Use of School Libraries and Collaboration with Teacher-Librarians and School Librarians in Japanese Language Arts: From a Survey of the Journal Kyoiku Kagaku Kokugo Kyoiku kn-title=学校図書館の活用と司書教諭・学校司書との協働をめぐる国語教育思潮の展開　―『教育科学国語教育』誌の調査から― en-subtitle= kn-subtitle= en-abstract=　School libraries are mentioned by government guidelines for teaching, and it is also closely related to Japanese language arts. Previous studies have reported the necessity of collaboration with teacher-librarians and school librarians. However, there has been no study of what kind of collaboration has been conducted in Japanese language arts to date. Therefore, the purpose of this study is to examine how school libraries are utilized in Japanese language arts based on a survey of educational journals, and to organize references to teacher-librarians and school librarians. As a result, we pointed out that while school libraries have been utilized in Japanese language arts in elementary and junior high schools, the collaboration with teacher-librarians and school librarians may not have been focused on, and that the reason for this is the lack of human resources, while some valuable collaborations can be found. kn-abstract=　学校図書館は，学習指導要領でも触れられており，国語科との関連も深い。また先行研究では，司書教諭や学校司書との協働の必要性が訴えられている。しかしこれまでの国語教育では，どのような協働がなされていたのかという検討がなされていない。そこで，本研究では，教育雑誌の調査をもとに，国語科においては，学校図書館がどのように活用されてきたのか，司書教諭や学校司書との協働はどのような態度がとられてきたのかを明らかにすることを目的とした。調査では，図書館に言及している論文や学校図書館を活用した実践・指導例を抽出し，分析した。実践・指導例の分析からは，小・中学校の国語科において学校図書館は活用されてきた一方で，司書教諭や学校司書との協働には着目が及んでいない状況が明らかになった。また，司書教諭や学校司書に関する言及からは，人的リソースにその原因を求める思潮が窺えたものの，価値ある協働も見受けられることを指摘した。 en-copyright= kn-copyright= en-aut-name=SAISHOYumi en-aut-sei=SAISHO en-aut-mei=Yumi kn-aut-name=最相有未 kn-aut-sei=最相 kn-aut-mei=有未 aut-affil-num=1 ORCID= en-aut-name=IKEDAMasafumi en-aut-sei=IKEDA en-aut-mei=Masafumi kn-aut-name=池田匡史 kn-aut-sei=池田 kn-aut-mei=匡史 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education（Professional Degree Corse），Okayama University kn-affil=岡山大学大学院教育学研究科大学院生 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=雑誌調査 (survey of journals) kn-keyword=雑誌調査 (survey of journals) en-keyword=読書指導 (reading instruction) kn-keyword=読書指導 (reading instruction) en-keyword=探究的な学習 (inquiry-based learning) kn-keyword=探究的な学習 (inquiry-based learning) en-keyword=国語教育史 (history of Japanese Language Arts) kn-keyword=国語教育史 (history of Japanese Language Arts) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=107 end-page=118 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Analysis of Practical Results of the Liberal Arts Education Class “Creativity in Life” at Okayama University V kn-title=大学教養教育における創造性を重視した探究型授業の評価　岡山大学教養教育科目「生活の中の創造性」の実践結果の分析V en-subtitle= kn-subtitle= en-abstract=　Since 2022, in the liberal arts education course “Modernity and Society,” a class entitled “Creativity in Life” has been implemented, in which students propose “Okadai Goods” using “color” as the theme.

That is, (1) The establishment of a foundation for organizational support that starts from collaboration, due to the correlation between factors showing high subscale scores unaffected by the number of years of career, and (2) The correlation among factors of motivational factors whose subscale scores increase with the number of years of career, which leads to the promotion of individualized support efforts, and (3) Correlation between factors of leader recognition and individual support seen in the career category of 11 years or more, and which leads to the promotion of expansion to management of organizational support. kn-abstract=　本研究の目的は，養護教諭のコーディネーション行動に影響する要因やその因子の傾向をキャリア年数から捉え，これらとコーディネーション行動の生起プロセスとの関係について明らかにすることであった。分析対象は，公立小学校・中学校勤務695名とした。キャリア年数の影響は，コーディネーション行動と動機づけの段階に関わる要因の尺度得点や，因子の下位尺度得点の向上に見られた。また，キャリア年数とコーディネーション行動の生起プロセスに関わる因子間の関係からは，（1）キャリア年数に影響されない高い下位尺度得点を示す因子間相関による，協働を起点にした組織支援の基盤づくり，（2）キャリア年数により下位尺度得点が高まる動機づけ要因の因子間相関による，個別支援の取組推進へのつながり，（3）11年以上キャリア区分で見られるリーダー認知と個別支援の因子間相関，及び組織的支援のマネジメントへの広がり，の３つの特徴をもつことが示唆された。 en-copyright= kn-copyright= en-aut-name=SUZUKIKaoru en-aut-sei=SUZUKI en-aut-mei=Kaoru kn-aut-name=鈴木薫 kn-aut-sei=鈴木 kn-aut-mei=薫 aut-affil-num=1 ORCID= en-aut-name=MIMURAYukari en-aut-sei=MIMURA en-aut-mei=Yukari kn-aut-name=三村由香里 kn-aut-sei=三村 kn-aut-mei=由香里 aut-affil-num=2 ORCID= affil-num=1 en-affil=Research student, United Graduate School of Education, Hyogo University of Teacher Education kn-affil=兵庫教育大学連合大学院教育学研究科研究生 affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=養護教諭 (Yogo teacher) kn-keyword=養護教諭 (Yogo teacher) en-keyword=コーディネーション行動 (coordination behavior) kn-keyword=コーディネーション行動 (coordination behavior) en-keyword=尺度得点 (scale score) kn-keyword=尺度得点 (scale score) en-keyword=下位尺度得点 (subscale scoreｒ) kn-keyword=下位尺度得点 (subscale scoreｒ) en-keyword=行動の生起プロセス (process of behavioral development) kn-keyword=行動の生起プロセス (process of behavioral development) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=45 end-page=58 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Childcare and Support in Nursery Schools for the Development of Geometry and Number Sense for Five-Year-Old Children kn-title=５歳児を対象とした数量・図形感覚を育む保育所保育の実際と援助の在り方 en-subtitle= kn-subtitle= en-abstract=This study focuses on “the interest and sense of numbers, geometry, and words”, which is regarded as one of "the Ideal Image by the End of Childhood". The focus is on 5-year-old pre-schoolers and their experiences with numbers and shapes in daily lives and games at nursery schools with a comparison with the mathematics classes in the first grade of elementary school. We also aim to provide insights for nursery schools on how to arouse children’s interest and support them to get familiar with geometry and numbers through games.
Our finding reveals that children naturally become familiar with geometry and numbers in their daily lives and their experiences become the foundation when they cope with elementary school mathematics. We also come to know that nursery teachers have to visualize the connection between their games with elementary school mathematics and actively arouse children’s interests and understanding. kn-abstract=　本研究では、幼児期の終わりまでに育って欲しい10の姿のひとつである、「数量・図形、文字等への関心・感覚」に着目し、就学前の５歳児に焦点を当て、保育所の日常生活や遊びにおいて子どもがどのような数量・図形に関する事柄を経験しているのか、また、その経験を小学校１年生の算数科の学習内容と照らして検討した。さらに、子どもが園生活や遊びの中で数量・図形に関心をもって親しみ、学びを得ることを支える保育の在り方について検討した。
　その結果、子どもは日常の中で主体的に数量・図形に親しむ経験をすると共に、その経験が小学校算数科の内容に連続する学びの基礎となっていることが明らかになった。また、保育士自身が小学校算数との繋がりを見通しながら、眼前の子どもの興味や関心に沿って援助することが専門的力量として求められることが示唆された。 en-copyright= kn-copyright= en-aut-name=SUZUKIFuka en-aut-sei=SUZUKI en-aut-mei=Fuka kn-aut-name=鈴木楓花 kn-aut-sei=鈴木 kn-aut-mei=楓花 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=Mitsu Kanagawa Certified childcare center kn-affil=岡山市御津金川認定こども園 affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 幼児教育講座 en-keyword=10 の姿 kn-keyword=10 の姿 en-keyword=数量・図形 kn-keyword=数量・図形 en-keyword=保育士 kn-keyword=保育士 en-keyword=専門的力量 kn-keyword=専門的力量 en-keyword=小学校算数科 kn-keyword=小学校算数科 en-keyword=the Ideal Image by the End of Childhood kn-keyword=the Ideal Image by the End of Childhood en-keyword=numbers & geometry kn-keyword=numbers & geometry en-keyword=professional nursery school teachers kn-keyword=professional nursery school teachers en-keyword=elementary school kn-keyword=elementary school en-keyword=mathematics kn-keyword=mathematics END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=33 end-page=44 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Systematic Improvement of Lessons in Elementary Schools ?A Case Study of Japanese Language Instruction Aimed at Realizing the “Ideal Child Image”? kn-title=小学校における組織的な授業改善のあり方　?「目指す子ども像」実現に向けた国語科指導を事例として? en-subtitle= kn-subtitle= en-abstract= kn-abstract=　本研究の目的は、「目指す子ども像」実現に向けた国語科の授業づくりの具体を検討し、小学校における組織的な授業改善のあり方を提言することにある。具体的には、「目指す子ども像」実現に向けた国語科の授業づくりを通して、今の社会が小学校教育に求める特色ある授業づくりの進め方を明らかにするため、勤務校である早島町立早島小学校に所属する教師の授業づくりを対象に事例研究を展開した。検討を通じて明らかになったことは、授業づくりにおける教師の思考・実践過程と、これらを実践者が反省的に捉え直すための「目指す子ども像」による言語活動具体化の手立てである。さらに、授業づくりの組織・系統性は、他学年教師の役割によってもたらされることが確認されたことから、それらを踏まえつつ、「目指す子ども像」実現に向けた授業づくりのあり方を体系化した。そうすることで、小学校における組織的な授業改善を進めていくための可能性が見出された。 en-copyright= kn-copyright= en-aut-name=KOMOTOAkihiro en-aut-sei=KOMOTO en-aut-mei=Akihiro kn-aut-name=河本章宏 kn-aut-sei=河本 kn-aut-mei=章宏 aut-affil-num=1 ORCID= en-aut-name=MIYAMOTOKoji en-aut-sei=MIYAMOTO en-aut-mei=Koji kn-aut-name=宮本浩治 kn-aut-sei=宮本 kn-aut-mei=浩治 aut-affil-num=2 ORCID= en-aut-name=IKEDAMasafumi en-aut-sei=IKEDA en-aut-mei=Masafumi kn-aut-name=池田匡史 kn-aut-sei=池田 kn-aut-mei=匡史 aut-affil-num=3 ORCID= en-aut-name=MATUDASatoshi en-aut-sei=MATUDA en-aut-mei=Satoshi kn-aut-name=松田聡 kn-aut-sei=松田 kn-aut-mei=聡 aut-affil-num=4 ORCID= affil-num=1 en-affil=Hayashima Elementary School (Graduate School of Education (Professional Degree Corse), Okayama University) kn-affil=岡山大学大学院教育学研究科大学院生 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=3 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=4 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=目指す子ども像 (The school's educational goals) kn-keyword=目指す子ども像 (The school's educational goals) en-keyword=価値目標 (into value-objectives) kn-keyword=価値目標 (into value-objectives) en-keyword=国語学力 (Japanese language ability) kn-keyword=国語学力 (Japanese language ability) en-keyword=カリキュラムマネジメント (Curriculum Management) kn-keyword=カリキュラムマネジメント (Curriculum Management) en-keyword=組織・系統性 (Organization and Systematic) kn-keyword=組織・系統性 (Organization and Systematic) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=17 end-page=31 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Research of the Image of Teacher-Training Courses among Student Teachers in Non-Faculty of Education kn-title=全学教職課程履修学生の教職課程イメージに関する研究 en-subtitle= kn-subtitle= en-abstract=The purpose of this study was to explore the image of teacher-training courses among student teachers in non-faculty of education. In this study, special attention to was paid to the difference first-year students and fourth-year students. This study 1 included student teachers in non-faculty of education. They were asked to answer metaphor-making task : “teacher-training courses”. Major findings (study 1) were as follows: (a) analysis of metaphors and reasons regarding the image of teacher-training course revealed 19 categories. (b) The category with the most number of descriptions was “A place to learn to become a teacher” followed by “A place to grow as a person”. (c) There were differences in the number of descriptions in some categories between first-year students and fourth-year students. Next, major findings (study 2) were as follows: (a) Exploratory factor analysis of the concept of image of teacher-training courses revealed 11 factors such as “place for active learning” and “hard”. (b) First-year students and fourth-year students had different scores on three factors: “Opportunity to reflect on the educational experience”, “Great value” and “A place for longterm leaning”. These studies indicated that student teachers in non-faculty of education had various images teacher-training courses, and that there were differences in some images teacher-training course between first-year students and fourth-year students. kn-abstract=　本研究の目的は，全学教職課程履修学生の教職課程イメージを検討することであった。研究１ではメタファー法を用いて全学教職課程履修学生を対象に教職課程イメージを調査し，19のカテゴリーが得られた。最も記述が多いカテゴリーは「教師になるための学びの場」であり，次いで「人としての成長の場」であった。また，1年生と4年生でいくつかのカテゴリーで有意差が見られた。研究２では，研究１を基に教職課程イメージを測定する尺度作成を試みると共に，1年生と4年生での比較を行った。調査の結果，教職課程イメージは「能動的な学びの場」「大変さ」など全11因子からなること，「被教育体験の振り返りの機会」「お得感」「長期的な学びの場」において1年生と4年生で有意差があること，が示唆された。本研究から全学教職課程履修学生の教職課程イメージの一端が明らかにされると共に，1年生と4年生で有しているイメージが部分的に異なる可能性が示唆された。 en-copyright= kn-copyright= en-aut-name=MISHIMATomotaka en-aut-sei=MISHIMA en-aut-mei=Tomotaka kn-aut-name=三島知剛 kn-aut-sei=三島 kn-aut-mei=知剛 aut-affil-num=1 ORCID= affil-num=1 en-affil=Center for Teacher Education and Development, Okayama University kn-affil=岡山大学教師教育開発センター en-keyword=全学教職課程履修学生 (student teachers in non-faculty of education) kn-keyword=全学教職課程履修学生 (student teachers in non-faculty of education) en-keyword=教職課程イメージ (image of teacher-training courses) kn-keyword=教職課程イメージ (image of teacher-training courses) en-keyword=メタファー (metaphor) kn-keyword=メタファー (metaphor) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=1 end-page=15 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Treatment of Learning about Marriage in High School Home Economics (2): Description Analysis of the Textbooks kn-title=高等学校家庭科における結婚に関する学習の扱い（2）　教科書の記述分析に基づいて en-subtitle= kn-subtitle= en-abstract= kn-abstract=　本稿では，「多様化する結婚」という日本の現状を踏まえ，結婚に関連する学習内容が，高等学校家庭科においてどのように扱われているかを分析することを目的とし，平成30年版の『高等学校学習指導要領』に基づいて構成された「家庭基礎」の教科書10冊を用いて結婚に関連する学習内容を分析した。分析の結果，教科書には，『指導要領』に基づいて結婚等に関連する法制度の記述がみられること，結婚をめぐる現状や変化を反映した学習内容が取り扱われていることを確認した。また，夫婦の氏，同性婚を取り上げ，具体的な学習活動について分析した結果，教科書によっては，知識や現状を提示する学習だけでなく，学習者である高校生が自ら考えること，選択すること，さらに他人の選択についても客観的に考えられるように問いかけている教科書もみられた。結婚に関連する法律，語句の掲載の有無，学習活動において，教科書によって取扱いの差があることが明らかになった。 en-copyright= kn-copyright= en-aut-name=TANABEShiho en-aut-sei=TANABE en-aut-mei=Shiho kn-aut-name=田邉詩歩 kn-aut-sei=田邉 kn-aut-mei=詩歩 aut-affil-num=1 ORCID= en-aut-name=LEEKyoungwon en-aut-sei=LEE en-aut-mei=Kyoungwon kn-aut-name=李m媛 kn-aut-sei=李 kn-aut-mei=m媛 aut-affil-num=2 ORCID= affil-num=1 en-affil=Fukuyama University kn-affil=福山大学 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=高等学校家庭科 (High School Home Economics) kn-keyword=高等学校家庭科 (High School Home Economics) en-keyword=教科書 (Textbooks) kn-keyword=教科書 (Textbooks) en-keyword=結婚 (Marriage) kn-keyword=結婚 (Marriage) en-keyword=多様化する結婚 kn-keyword=多様化する結婚 en-keyword=Course of Study kn-keyword=Course of Study END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大学教師教育開発センター紀要 第15号 全文（一括ダウンロード用） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=8502 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Age-specific assessment of initial hemoglobin levels and shock index for predicting life-saving interventions in pediatric blunt liver and spleen injuries en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to evaluate the effectiveness of combining initial hemoglobin levels with the shock index for predicting the need for life-saving interventions (LSI) in pediatric patients with blunt liver and spleen injuries (BLSI), specifically tailored to different age groups. This was a multicenter retrospective cohort study of pediatric patients with BLSI in Japan. The area under the receiver operating characteristic curve (AUROC) were used to assess predictive accuracy. The study included 1,370 patients. LSI was required in 59 of 247 (23.9%) aged 1 to 6 years, 100 of 402 (24.9%) aged 7 to 12 years, and 125 of 297 (42.1%) patients aged 13 to 16 years. Within each specific age group, the predictability was categorized as fair and appeared higher than that of the entire cohort or when using either parameter alone. Notably, in the 1 to 6-year age group, the combined values showed the highest predictability, which was statistically superior to the shock index alone (AUROC of 0.770 vs. 0.671, P = 0.025). Tailoring initial hemoglobin levels and shock index to specific age groups enhances predictability of LSI in pediatric BLSI, showing a fair level of predictive accuracy. en-copyright= kn-copyright=

It is evident that higobiwa borrowed stories from other genres and adapted them to its own distinctive narrative style. The findings of this research focused on the Heike-related tales reveal significant similarities between the tales of Ichi-no-Tani and Ko-Atsumori in the blind biwa players' tradition and Ko-Atsumori in the kojoruri tradition. These parallels suggest a shared narrative lineage between these two performance genres, prompting a reevaluation of our understanding of the transmission and evolution of oral narratives within the blind biwa players' tradition of Kyushu and shedding light on the dynamic nature and the interconnectedness of different performance traditions within Japan. 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=Institute of Global Human Resource Development, Okayama University kn-affil= en-keyword=higobiwa kn-keyword=higobiwa en-keyword=the blind biwa players' tradition kn-keyword=the blind biwa players' tradition en-keyword=kojoruri kn-keyword=kojoruri en-keyword=Ichi-no-Tani kn-keyword=Ichi-no-Tani en-keyword=Ko-Atsumori kn-keyword=Ko-Atsumori END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue= article-no= start-page=13 end-page=32 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250314 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Research on Factors Promoting Study in Japan : Cases of International Students from South-East Asia kn-title=日本への留学を促進する要因に関する研究　−東南アジアからの留学生を事例として− en-subtitle= kn-subtitle= en-abstract=In this study, international students from Southeast Asia were asked, 'Why did you decide to study in Japan?' and the information was collected through semi-structured interviews.

Adults aged 18 years and over were surveyed and 11018 people (mean age 39.47 years) responded. The Adult ADHD Self-Rating Scale was used. For each sexual minority, a t-test was performed for ADHD scores and subscale scores of “inattention,” “hyperactivity,” and “impulsivity,” and a x2 test was performed for the number of persons above the cut-off. All sexual minority groups had significantly higher ADHD and subscale scores and significantly more people above the cut-off scores, so the close association was evident. There was no significant difference in ADHD scores or numbers of persons between transwomen and transmen. kn-abstract=　様々なセクシュアルマイノリティと発達障害のADHD（Attention Deficit Hyperactivity Disorder）との関連を明らかにするため， WEB調査を行った。18歳以上の成人を対象とし，11,018人（平均年39.47歳）から回答を得た。ADHDを測る質問紙は「成人期ADHD検査（A-ADHD）」を使用した。セクシュアルマイノリティごとに， ADHD得点と下位尺度「不注意」「多動性」「衝動性」得点についてt検定，カットオフ54点以上の人数についてx2検定を行った。全てのセクシュアルマイノリティで有意にADHDと下位尺度得点が高く，カットオフ得点以上の人数も有意に多かった。なおトランスウーマンとトランスマンでADHD得点や人数に有意な差は見られなかった。以上から，セクシュアルマイノリティとADHDは密接に関係している事が明らかとなった。 en-copyright= kn-copyright= en-aut-name=MATSUIMegumi en-aut-sei=MATSUI en-aut-mei=Megumi kn-aut-name=松井めぐみ kn-aut-sei=松井 kn-aut-mei=めぐみ 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=セクシュアルマイノリティ kn-keyword=セクシュアルマイノリティ en-keyword=発達障害 kn-keyword=発達障害 en-keyword=ADHD kn-keyword=ADHD en-keyword=注意欠如・多動症 kn-keyword=注意欠如・多動症 END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250314 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=195 cd-vols= no-issue= article-no= start-page=123743 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=Utility of Surgical Simulation for Tubular Retractor Surgery Using Three-Dimensional Printed Intraventricular Tumor Models: Case Series en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: The utility of the tubular retractor for deep-seated tumors, including intraventricular tumors, has recently been reported. However, the surgical field’s depth and narrowness can lead to blind spots, and it is crucial to prevent damage to the cortex and white matter fibers in eloquent areas. Therefore, preoperative simulation is critical for tubular retractor surgery. In this study, we investigated the benefits of threedimensional (3D)-printed intraventricular tumor models for tubular retractor surgery.
Methods: Nine patients with intraventricular central neurocytoma who underwent tubular retractor surgery at our institution between March 2013 and August 2023 were retrospectively reviewed. Fusion images and 3D-printed intraventricular tumor models were developed from preoperative computed tomography (CT) and magnetic resonance imaging (MRI). The puncture points of the tubular retractor were simulated using fusion images and 3D-printed intraventricular tumor models by 11 neurosurgeons (3 experts in brain tumors, 2 experts in areas other than brain tumors, and 6 residents). The dispersion of puncture points among 8 neurosurgeons (excluding brain tumor experts) was compared in each simulation model.
Results: These cases were categorized into two groups based on the dispersion of puncture points simulated by fusion images. Puncture point dispersion was markedly smaller in all cases when using 3D-printed intraventricular tumor models compared to simulations solely based on fusion images.
Conclusions: In intraventricular tumor surgery using a tubular retractor, 3D-printed intraventricular tumor models proved more beneficial in preoperative simulation compared to fusion images. en-copyright= kn-copyright= en-aut-name=OmaeRyo en-aut-sei=Omae en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=SaijoTomoya en-aut-sei=Saijo en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=NishigakiShohei en-aut-sei=Nishigaki en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IkemachiRyosuke en-aut-sei=Ikemachi en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=IshidaJoji en-aut-sei=Ishida en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 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 Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=3D-printed model kn-keyword=3D-printed model en-keyword=Case series kn-keyword=Case series en-keyword=Intraventricular tumors kn-keyword=Intraventricular tumors en-keyword=Preoperative surgical simulation kn-keyword=Preoperative surgical simulation en-keyword=Tubular retractor kn-keyword=Tubular retractor END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=5248 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Changes of leucine-rich alpha 2 glycoprotein could be a marker of changes of endoscopic and histologic activity of ulcerative colitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Leucine-rich alpha 2 glycoprotein (LRG) is one of the serum biomarkers for disease activity of ulcerative colitis (UC). We focused on the correlation between the changes of LRG and the changes of endoscopic and histologic activity of UC, in comparison to the changes of fecal calprotectin (Fcal), fecal immunochemical test (FIT), and C-reactive protein (CRP). Seventy-nine patients with two or more colonoscopies were enrolled, and 123 paired colonoscopies and 121 paired biopsies were examined. With regard to the change of endoscopic/histologic activity between the preceding and subsequent colonoscopy, there was improvement (n = 29/45), unchanging (n = 63/36), and worsening (n = 31/40). The correlations between the changes of marker levels and endoscopic/histologic activity were Fcal; r = 0.50/0.39 and FIT; r = 0.41/0.40, LRG; r = 0.42/0.40 and CRP; r = 0.22/0.17. Furthermore, when the correlation between the changes of LRG levels and the changes of endoscopic/histological activity was compared with those of other markers, the correlation of LRG tended to be superior to those of CRP (CRP vs. LRG; p = 0.08/0.01). LRG is equivalent to fecal markers and superior to CRP, when inferring changes in disease activity of UC based on changes in its level. en-copyright= kn-copyright= en-aut-name=AoyamaYuki

世紀前半のアメリカを代表する画家として評価される洋画家・国吉康雄（1889-1953）。本論では，その画業と作品評価について論じるわが国の研究者の記述を，作家の没後の1954 年に国立近代美術館（現国立東京近代美術館）で開催された「国吉康雄遺作展」を起点とし，20 世紀中に開催された主な展覧会と，2004 年に同じく東京国立近代美術館などで開催された「国吉康雄展」で確認した。結果，日本人による国吉作品の表現が，この1954 年時に決定づけられていることに，別の捉え方を提示されるまでに40 年の歳月を要していることが明らかとなった。 en-copyright= kn-copyright= en-aut-name=ITOShun en-aut-sei=ITO en-aut-mei=Shun

　その結果，他教科の中学校学習指導要領解説の記載内容から，学生は家庭科と各教科との関連性を認識し，他者の生活に対する価値観や考え方について理解を深めること，個人の生活が社会に影響を与えることについて理解を深めることなど，家庭科の学習が担う役割を新たに認識することができたと推察された。また，授業後の家庭科に対する教科観は，比較対象とした他教科による影響が見られ，「多様な生き方」，「様々な価値観や生き方」，「社会での課題を発見し，改善する力」，「未来の社会をつくる」等の新たな記述が見られた。 en-copyright= kn-copyright= en-aut-name=TAKUMAChiharu en-aut-sei=TAKUMA en-aut-mei=Chiharu kn-aut-name=詫間千晴 kn-aut-sei=詫間 kn-aut-mei=千晴 aut-affil-num=1 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=家庭科教員養成課程 kn-keyword=家庭科教員養成課程 en-keyword=教科観 kn-keyword=教科観 en-keyword=家庭科 kn-keyword=家庭科 en-keyword=他教科 kn-keyword=他教科 en-keyword=比較 kn-keyword=比較 END start-ver=1.4 cd-journal=joma no-vol=188 cd-vols= no-issue= article-no= start-page=85 end-page=104 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Practice and Examination of Remaking Aprons Using Old Shirts in Elementary School Home Economics Classes: Development of the Home Economics Curriculum Based on the ESD (W) kn-title=小学校家庭科における古ワイシャツを用いたリメイクエプロン製作の実践と検討 ― ESDを視点とした家庭科教育内容開発研究（W）― en-subtitle= kn-subtitle= en-abstract= kn-abstract=　本継続研究の目的は，学校教育に社会的使命として求められているESDを視点とした小・中・高等学校家庭科の教育内容開発を行うことにある。本稿では，小学校家庭科において，従来，最も多くの学習時間が充てられてきた「被服製作学習」が「布を用いた製作」となり，製作時間短縮のために，市販のキットを用いた袋類やエプロン製作が実践されていることに着目し，古ワイシャツを用いたリメイクエプロンの製作を通して，児童に「自分と被服との関係」と「リメイクの意味」を考えさせる授業を開発し，この実践結果から小学校家庭科における「製作学習」の問い直しを行った。 en-copyright= kn-copyright= en-aut-name=SATOSono en-aut-sei=SATO en-aut-mei=Sono kn-aut-name=佐藤園 kn-aut-sei=佐藤 kn-aut-mei=園 aut-affil-num=1 ORCID= en-aut-name=HIRATAMichiko en-aut-sei=HIRATA en-aut-mei=Michiko kn-aut-name=平田美智子 kn-aut-sei=平田 kn-aut-mei=美智子 aut-affil-num=2 ORCID= en-aut-name=NOBUKIYOAkiko en-aut-sei=NOBUKIYO en-aut-mei=Akiko kn-aut-name=信清亜希子 kn-aut-sei=信清 kn-aut-mei=亜希子 aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=2 en-affil=Kurashiki Washu High School kn-affil=岡山県立倉敷鷲羽高等学校 affil-num=3 en-affil=Kibichuo Town Toyono Elementary School kn-affil=岡山県吉備中央町立豊野小学校 en-keyword=家庭科 kn-keyword=家庭科 en-keyword=ESD kn-keyword=ESD en-keyword=内容開発研究 kn-keyword=内容開発研究 en-keyword=リメイクエプロン kn-keyword=リメイクエプロン en-keyword=小学校 kn-keyword=小学校 END start-ver=1.4 cd-journal=joma no-vol=188 cd-vols= no-issue= article-no= start-page=77 end-page=84 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Basic Research on the Appreciation of Sculpture Works by Children in Schools for the Blind -Through the Arrangement of Issues Based on the Literature Survey- kn-title=「創造性が社会と出会う美術教育」による教員の学びに関する基礎研究 ―「市井 no 姿勢 ni 学ぶプロジェクト」の課題整理 ― en-subtitle= kn-subtitle= en-abstract= kn-abstract=　本論文は，美術科の教員が新しい価値の生成を目指した授業研究やカリキュラム構築を行うための基礎研究にあたるものであり，その目的は，教員も新しい価値を求めて学び続ける力を培うために「市井no姿勢ni学ぶ」プロジェクト（以下，市井プロジェクトと表記）の有用性を確認することである。市井プロジェクトとは，@教員が日常生活で出会った他者と会い，A他者が学んできたことについてインタビューし，BAを生かした授業を実施し，CAで話を聞かせていただいた他者とBの授業検討を行うというものである。本論文では，@とAの成果と課題をまとめた。成果は，Aインタビューを通して教員自身の学びが変容する姿を確認し，インタビュー相手であるK氏自身にも変容が見られたことである。その一方で，課題は，K氏とインタビューの質問者との関係性による検討が行えていない点である。 en-copyright= kn-copyright= en-aut-name=MATSUURAAi en-aut-sei=MATSUURA en-aut-mei=Ai kn-aut-name=松浦藍 kn-aut-sei=松浦 kn-aut-mei=藍 aut-affil-num=1 ORCID= en-aut-name=SENOYusuke en-aut-sei=SENO en-aut-mei=Yusuke kn-aut-name=妹尾佑介 kn-aut-sei=妹尾 kn-aut-mei=佑介 aut-affil-num=2 ORCID= en-aut-name=KIYOTATetsuo en-aut-sei=KIYOTA en-aut-mei=Tetsuo kn-aut-name=清田哲男 kn-aut-sei=清田 kn-aut-mei=哲男 aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=2 en-affil=Okayama Prefectural Tamashima High School kn-affil=岡山県立玉島高等学校 affil-num=3 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=美術教育 kn-keyword=美術教育 en-keyword=創造性 kn-keyword=創造性 en-keyword=研修 kn-keyword=研修 END start-ver=1.4 cd-journal=joma no-vol=188 cd-vols= no-issue= article-no= start-page=67 end-page=76 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Music Education Practice Based on the Region: An Improvisation Workshop at a Public Elementary School in Tamano City, Okayama kn-title=地域を見つめ直す音楽教育実践の検討 ― 岡山県玉野市内の公立小学校における即興演奏ワークショップを例に ― en-subtitle= kn-subtitle= en-abstract= kn-abstract=　本研究は，地域の文化や遺産，環境を念頭に置いた創造的な音楽教育によって，県内の人口減少に起因する課題の改善を図ることを目的としている。同時に，その創作教育を通じて，児童の柔軟な創造力や多様性を認める意識を育むこともねらっている。本研究において実践した取組は，現代音楽的表現を取り入れた即興演奏ワークショップである。

This investigation assessed the intention and determinant factors of COVID-19 vaccination among healthcare workers in Japan in the 2024?2025 pre-season.
Methods: A retrospective survey was conducted utilizing data collected from hospital staff at Okayama University Hospital, Japan, to inform the COVID-19 vaccination strategy in October 2024. The analysis evaluated demographic characteristics, vaccine intention, perceived barriers to vaccination, and maximum acceptable out-of-pocket expenditure.
Results: The study population of 3417 respondents comprised 843 medical doctors (24.7 %), 1131 nurses (33.1 %), 320 other medical staff (9.4 %), 286 dental doctors (8.4 %), and 627 administrative officers (18.3 %). At full cost, 2109 (61.7 %) indicated no intention to receive vaccination, while only 4.4 % expressed willingness to be vaccinated and 33.9 % remained undecided. With total self-payment, the vaccination acceptance rates were the highest and lowest among medical doctors (11.4 %) and nurses (1.0 %), respectively. Cost (38.1 %), followed by safety issues (29.5 %) and concerns regarding efficacy or medical necessity (20.3 %), emerged as the primary barrier. The projected vaccination intention increased to 43.9 % and 54.9 % at reduced self-pay costs of 3000 JPY and 5000 JPY, respectively.
Conclusions: Addressing financial constraints through policy interventions could be effective strategies in increasing overall vaccination coverage among healthcare workers. In addition, providing tailored education on vaccine safety, efficacy, and necessity may further facilitate increased vaccine uptake within this critical population. en-copyright= kn-copyright= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujitaYasushi en-aut-sei=Fujita en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=ManabeYohei en-aut-sei=Manabe en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=2 en-affil=Division of Infection Prevention and Control, Okayama University Hospital kn-affil= affil-num=3 en-affil=Division of Infection Prevention and Control, Okayama University Hospital kn-affil= affil-num=4 en-affil=Division of Infection Prevention and Control, Okayama University Hospital kn-affil= en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=Immunization kn-keyword=Immunization en-keyword=Reimbursement kn-keyword=Reimbursement en-keyword=Healthcare workers kn-keyword=Healthcare workers en-keyword=Financial support kn-keyword=Financial support END start-ver=1.4 cd-journal=joma no-vol=209 cd-vols= no-issue= article-no= start-page=114663 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=Repeated sequential administration of pegylated emulsion of SU5416 and liposomal paclitaxel enhances anti-tumor effect in 4T1 breast cancer-bearing mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=To improve vascular normalization strategy for intractable triple-negative breast cancer 4T1, we examined the anti-tumor effects of repeated sequential administration of polyethylene glycol (PEG)-modified emulsion of SU5416 (PE-SU5416), a vascular endothelial growth factor (VEGF) receptor-2 kinase inhibitor, and PEG-modified liposomal paclitaxel (PL-PTX) in mice bearing 4T1 cells. Three sequential administrations (Seq×3) of PE-SU5416 and PL-PTX exhibited significantly higher anti-tumor activity than a single sequential administration (Seq×1). The tumor vasculatures were structurally normalized until after two PE-SU5416 (PE-SU5416×2) or sequential (Seq×2) administrations, while the improvement in vascular function, such as oxygen supply, blood flow, and PEG-liposomal distribution, was evident until after three administrations of PE-SU5416 (PE-SU5416×3) and Seq×3. Although some discrepancies between the structural and functional improvement in tumor vasculatures were observed after PE-SU5416×3 and Seq×3, cancer-associated fibroblasts (CAFs) and collagen levels were significantly reduced after PE-SU5416×2, PE-SU5416×3, Seq×2, and Seq×3, suggesting that a possible decrease in interstitial fluid pressure due to the reduction in CAFs and collagen would have compensated for vascular function. Furthermore, PE-SU5416×2, PE-SU5416×3, Seq×2, and Seq×3 significantly decreased tumor growth factor-β (TGF-β), an activator of CAFs, in tumor tissues, suggesting that the reduction in TGF-β levels by PE-SU5416 suppresses CAF activation. en-copyright= kn-copyright= en-aut-name=MaruyamaMasato en-aut-sei=Maruyama en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ToriiReiya en-aut-sei=Torii en-aut-mei=Reiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuiHazuki en-aut-sei=Matsui en-aut-mei=Hazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HayashiHiroki en-aut-sei=Hayashi en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OgawaraKen-ichi en-aut-sei=Ogawara en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HigakiKazutaka en-aut-sei=Higaki en-aut-mei=Kazutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Pharmaceutics, Faculty of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pharmaceutics, Faculty of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pharmaceutics, Faculty of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pharmaceutics, Faculty of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Laboratory of Pharmaceutics, Kobe Pharmaceutical University kn-affil= affil-num=6 en-affil=Department of Pharmaceutics, Faculty of Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Drug delivery kn-keyword=Drug delivery en-keyword=Vascular normalization kn-keyword=Vascular normalization en-keyword=Breast cancer kn-keyword=Breast cancer en-keyword=Liposome kn-keyword=Liposome en-keyword=Cancer-associated fibroblast kn-keyword=Cancer-associated fibroblast END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=2 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Enhancing Campus Environment: Real-Time Air Quality Monitoring Through IoT and Web Technologies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, enhancing campus environments through mitigations of air pollutions is an essential endeavor to support academic achievements, health, and safety of students and staffs in higher educational institutes. In laboratories, pollutants from welding, auto repairs, or chemical experiments can drastically degrade the air quality in the campus, endangering the respiratory and cognitive health of students and staffs. Besides, in universities in Indonesia, automobile emissions of harmful substances such as carbon monoxide (CO), nitrogen dioxide (NO2), and hydrocarbon (HC) have been a serious problem for a long time. Almost everybody is using a motorbike or a car every day in daily life, while the number of students is continuously increasing. However, people in many campuses including managements do not be aware these problems, since air quality is not monitored. In this paper, we present a real-time air quality monitoring system utilizing Internet of Things (IoT) integrated sensors capable of detecting pollutants and measuring environmental conditions to visualize them. By transmitting data to the SEMAR IoT application server platform via an ESP32 microcontroller, this system provides instant alerts through a web application and Telegram notifications when pollutant levels exceed safe thresholds. For evaluations of the proposed system, we adopted three sensors to measure the levels of CO, NO2, and HC and conducted experiments in three sites, namely, Mechatronics Laboratory, Power and Emission Laboratory, and Parking Lot, at the State Polytechnic of Malang, Indonesia. Then, the results reveal Good, Unhealthy, and Dangerous for them, respectively, among the five categories defined by the Indonesian government. The system highlighted its ability to monitor air quality fluctuations, trigger warnings of hazardous conditions, and inform the campus community. The correlation of the sensor levels can identify the relationship of each pollutant, which provides insight into the characteristics of pollutants in a particular scenario. en-copyright= kn-copyright= 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=1 ORCID= en-aut-name=SyaifudinYan Watequlis en-aut-sei=Syaifudin en-aut-mei=Yan Watequlis kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SetiawanBudhy en-aut-sei=Setiawan en-aut-mei=Budhy kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=PandumanYohanes Yohanie Fridelin en-aut-sei=Panduman en-aut-mei=Yohanes Yohanie Fridelin 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= affil-num=1 en-affil=Department of Electrical Engineering, State Polytechnic of Malang kn-affil= affil-num=2 en-affil=Department of Information Technology, State Polytechnic of Malang kn-affil= affil-num=3 en-affil=Department of Electrical Engineering, State Polytechnic of Malang 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 kn-keyword=Internet of Things en-keyword= campus air quality kn-keyword= campus air quality en-keyword= pollutant detection kn-keyword= pollutant detection en-keyword= SEMAR kn-keyword= SEMAR en-keyword= sensor technology kn-keyword= sensor technology en-keyword= web application kn-keyword= web application END start-ver=1.4 cd-journal=joma no-vol=197 cd-vols= no-issue= article-no= start-page=115301 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=Fraglide-1 from traditional Chinese aromatic vinegar: A natural AhR antagonist for atopic dermatitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Traditional Chinese Zhenjiang aromatic vinegar (Kozu) contains Fraglide-1 (FG1), a bioactive lactone with demonstrated peroxisome proliferator-activated receptor gamma (PPARγ) agonist and antioxidant activities. This study explored FG1's novel ability to antagonize the aryl hydrocarbon receptor (AhR) signaling pathway, which regulates artemin expression and contributes to itching and inflammation in atopic dermatitis. Through molecular docking simulations and cell-based assays in human keratinocytes, we demonstrated FG1's potent antagonistic activity against AhR signaling. FG1 effectively suppressed FICZ-induced inflammatory responses, including artemin expression, with potency (half maximal inhibitory concentration, IC50 = 5.1 μM) comparable to the synthetic antagonist StemRegenin 1 (SR1) while demonstrating a superior safety profile (median lethal concentration, LC50 > 100 μM vs. 27.5 μM for SR1). These findings expand our understanding of bioactive compounds from traditional fermented foods and their regulatory effects on AhR signaling, providing a foundation for future studies on FG1's role in modulating skin inflammation. en-copyright= kn-copyright= en-aut-name=KatoKosuke en-aut-sei=Kato en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AkamatsuMiki en-aut-sei=Akamatsu en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KakimaruSaya en-aut-sei=Kakimaru en-aut-mei=Saya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KoreishiMayuko en-aut-sei=Koreishi en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakagiMasahiro en-aut-sei=Takagi en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyashitaMasahiro en-aut-sei=Miyashita en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 ORCID= en-aut-name=SatohAyano en-aut-sei=Satoh en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TsujinoYoshio en-aut-sei=Tsujino en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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 Environmental and Life Science, 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=School of Materials Science, Japan Advanced Institute of Science and Technology kn-affil= affil-num=6 en-affil=Graduate School of Agriculture, Kyoto 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= affil-num=9 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=10 en-affil=Graduate School of Science, Technology and Innovation, Kobe University kn-affil= en-keyword=AhR kn-keyword=AhR en-keyword=Xenobiotic responsive element kn-keyword=Xenobiotic responsive element en-keyword=StemRegenin 1 kn-keyword=StemRegenin 1 en-keyword=ARNT kn-keyword=ARNT en-keyword=Atopic dermatitis kn-keyword=Atopic dermatitis en-keyword=Artemin kn-keyword=Artemin 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=20250212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Spatiotemporal expression pattern of dyslexia susceptibility 1 candidate 1 (DYX1C1) during rat cerebral cortex development en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Developmental dyslexia (DD) is a common learning disorder with significant consequences for affected individuals. Although several candidate genes, including dyslexia susceptibility 1 candidate 1 (DYX1C1), have been implicated in dyslexia, their role in brain development remains unclear. We aimed to elucidate the spatiotemporal expression patterns of DYX1C1 during cerebral cortex development in rats.
Methods We investigated DYX1C1 expression during cerebral cortex development using rat embryos at various gestational stages (E13.5, 15.5, 17.5 and 20.5) by immunohistochemistry (n?=?7 embryos/stage), quantitative real-time PCR (n?=?6), and in situ hybridization (n?=?11?15).
Results The DYX1C1-positive cells were predominantly located in the outermost layers of the cortical plate, particularly at E15.5. DYX1C1 mRNA expression peaked at E15.5 and subsequently declined. DYX1C1-positive cells did not co-localize with reelin-positive Cajal-Retzius cells, but co-localized with neuronal markers expressed during development, and had shorter primary cilia than DYX1C1-negative cells.
Conclusions Our findings highlight the dynamic expression of DYX1C1 in the developing cerebral cortex of rats, implicating its involvement in neurodevelopmental processes. Further investigation of the functional interactions of DYX1C1, particularly its relationship with reelin and its role in cerebrocortical and hippocampal development, may provide insights into the pathophysiology of dyslexia and neurodevelopmental disorders. en-copyright= kn-copyright= en-aut-name=ZenshoKazumasa en-aut-sei=Zensho en-aut-mei=Kazumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyazakiIkuko en-aut-sei=Miyazaki en-aut-mei=Ikuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IsseAika en-aut-sei=Isse en-aut-mei=Aika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MisawaIchika en-aut-sei=Misawa en-aut-mei=Ichika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasaiKaori en-aut-sei=Masai en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkaMakio en-aut-sei=Oka en-aut-mei=Makio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=AsanumaMasato en-aut-sei=Asanuma en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Psychosocial Medicine, National Center for Child Health and Development kn-affil= affil-num=7 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=99 cd-vols= no-issue=3 article-no= start-page=e02166-24 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250213 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A capsidless (+)RNA yadokarivirus hosted by a dsRNA virus is infectious as particles, cDNA, and dsRNA en-subtitle= kn-subtitle= en-abstract= kn-abstract=Capsidless yadokariviruses (members of the order Yadokarivirales) with (+)RNA genomes divert the capsid of their partner icosahedral double-stranded RNA (dsRNA) viruses in different families of the order Ghabrivirales into the replication site. A yadokarivirus, AfSV2, has been reported from a German strain of the ascomycete fungus Aspergillus foetidus coinfected by two dsRNA viruses, a victorivirus (AfSV1, family Pseudototiviridae) and an alternavirus (AfFV, family Alternaviridae). Here, we identified AfSV1 as the partner of AfSV2 in a Japanese A. foetidus strain after showing the infectiousness of AfSV2 in three forms: virus particles (heterocapsid), transforming full-length complementary DNA (cDNA), and purified replicated form (RF) dsRNA that is believed to be inactive as a translational template. Virion transfection of virus-free A. foetidus protoplasts resulted in the generation of two strains infected either by AfSV1 alone or by both AfSV1 and AfSV2. Transformants with AfSV2 full-length cDNA launched AfSV2 infection only in the presence of AfSV1, but not those with AfSV2 RNA-directed RNA polymerase mutant cDNA. The purified fractions containing AfSV2 RF dsRNA also launched infection when transfected into protoplasts infected by AfSV1. Treatment with dsRNA-specific RNase III, but not with proteinase K, S1 nuclease, or DNase I, abolished the infectivity of AfSV2 RF dsRNA. Furthermore, we confirmed the infectiousness of gel-purified AfSV2 RF dsRNA in the presence of AfSV1. Taken together, our results show the unique infectious entity of AfSV2 and the expansion of yadokarivirus partners in the family Pseudototiviridae and provide interesting evolutionary insights. en-copyright= kn-copyright= en-aut-name=FadliMuhammad en-aut-sei=Fadli en-aut-mei=Muhammad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HisanoSakae en-aut-sei=Hisano en-aut-mei=Sakae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NovoaGuy en-aut-sei=Novoa en-aut-mei=Guy kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Cast?nJos?

Soy protein has been found to inhibit fat accumulation effectively, and soybeans contain isoflavones, saponins, phytic acid, and other substances with preventive and therapeutic effects on heart disease, cancer, and diabetes. Furthermore, processed soybean products, such as Avocado-Soybean unsaponifiable, Tempeh, and Bowman-Birk inhibitor, have demonstrated health benefits. These products have been shown to have antibacterial, antioxidant, and anticancer effects in oral diseases. Numerous experiments have provided evidence of the antibacterial, antioxidant, and anticancer effects of polyunsaturated fatty acids, isoflavones, and soybean polypeptides. This comprehensive review assesses the relationship and mechanism of soybeans and their derivatives on oral diseases, providing valuable insights into their prevention and treatment. en-copyright= kn-copyright= en-aut-name=CanyanKuang en-aut-sei=Canyan en-aut-mei=Kuang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AriasZulema Rosalia en-aut-sei=Arias en-aut-mei=Zulema Rosalia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=YamamotoTadashi en-aut-sei=Yamamoto en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=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 Pathophysiology?Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pathophysiology?Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pathophysiology?Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=The Center for Graduate Medical Education (Dental Division), Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Pathophysiology?Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pathophysiology?Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=soybean kn-keyword=soybean en-keyword=soy products kn-keyword=soy products en-keyword=oral diseases kn-keyword=oral diseases en-keyword=dental application kn-keyword=dental application en-keyword=antibacterial effect kn-keyword=antibacterial effect en-keyword=antioxidant kn-keyword=antioxidant en-keyword=anticancer kn-keyword=anticancer END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue= article-no= start-page=103026 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=The antimalarial activity of transdermal N-89 mediated by inhibiting ERC gene expression in P. Berghei-infected mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Through studies of new antimalarial drugs, we identified 1,2,6,7-tetraoxaspiro[7.11]nonadecane (N-89) as a potential drug candidate. Here, we analyzed the antimalarial action of a transdermal formulation (td) of N-89, designed for easy use by children, using Plasmodium berghei-infected mice as a model for malaria patients. The td N-89 or artemisinin (ART) formulation was transdermally administered to P. berghei-infected mice with 0.2?0.4 % parasitemia, twice daily for four days, at an effective dose of 90 % for malaria. Parasitemia was decreased in td N-89 and td ART groups during the drug treatment; then, three of the eight mice in td N-89 group were completely cured without relapse. Additionally, abnormal trophozoites in td N-89 group were observed 8 h after administration and increased up to 24 h. To study the change in endoplasmic reticulum-resident calcium-binding protein (ERC) gene expression with td N-89, we investigated the gene expression of P. berghei ERC (PbERC) after td N-89 treatment. PbERC gene expression was increased time-dependently in control group, and was statistically decreased at 4 and 8 h and then increased similar to that of control group at 12 h in td ART group. In contrast, the expression in td N-89 group was almost steady starting from 0 h. We also studied parasite egress-related genes expression after td N-89 treatment, plasmepsin X, subtilisin-like protease 1 and merozoite surface protein 1, were suppressed at 12 h compared to control group. These results suggest that N-89 affects function of endoplasmic reticulum via regulating gene suppression and subsequently parasite growth is inhibited. en-copyright= kn-copyright= en-aut-name=MatsumoriHiroaki en-aut-sei=Matsumori en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DinhThi Quyen en-aut-sei=Dinh en-aut-mei=Thi Quyen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=MoritaMasayuki en-aut-sei=Morita en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimHye-Sook en-aut-sei=Kim en-aut-mei=Hye-Sook kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Division of International Infectious Diseases Control, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Division of International Infectious Diseases Control, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Research Center for Intestinal Health Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Anatomy, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Division of International Infectious Diseases Control, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Synthetic antimalarial endoperoxide kn-keyword=Synthetic antimalarial endoperoxide en-keyword=Transdermal N-89 kn-keyword=Transdermal N-89 en-keyword=Artemisinin kn-keyword=Artemisinin en-keyword=In vivo kn-keyword=In vivo en-keyword=Abnormal trophozoite kn-keyword=Abnormal trophozoite en-keyword=Endoplasmic reticulum-resident calcium-binding protein (ERC) kn-keyword=Endoplasmic reticulum-resident calcium-binding protein (ERC) en-keyword=Parasite egress-related gene kn-keyword=Parasite egress-related gene END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=199 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Establishment of a rapid and quantitative method for detecting the range of infection exposure in preclinical dental education en-subtitle= kn-subtitle= en-abstract= kn-abstract=Backgrounds Safe dental treatments that prevent nosocomial and cross-infections are essential for patients and dental workers. However, dental students sometimes pay inadequate attention to infection control, especially in preclinical practice, because of too much focus on technical training, such as the use of equipment, etc. The spread of infections such as SARS-CoV-2, antibiotic-resistant bacteria, and oral bacteria are sometimes lethal for medically compromised patients. Thus, the rapid and inexpensive detection system to detect and measure dental practice-related infection spread during preclinical treatment is highly desired for dental education. This study aimed to establish a method to quantify and visualize infected areas using dental phantoms for safe and effective preclinical dental practices.
Methods At first, we developed artificial saliva as an in vitro study, including food-derived bacteria and fluorescence dye, which is safe for application to preclinical practice education. In vitro study, the correlation between adenosine triphosphate (ATP) levels and Lactobacillus colony numbers in yogurt was examined using the ATP fluorescent method, with colony counting on yogurt only and a mixture of yogurt and ultraviolet (UV)-sensitive hand lotion. The mixed liquid of yogurt and hand lotion was used as artificial saliva. Second, we used this artificial saliva in preclinical education. The degree of contamination of personal protective equipment and dental chairs in preclinical practice using this artificial saliva was determined using the ATP fluorescent method and measuring the luminescence areas among 10 dentists, 10 dental residents, and 10 fifth-grade dental students.
Results ATP levels and Lactobacillus colony numbers in yogurt were positively correlated with yogurt alone and a mixture of yogurt and UV-sensitive hand lotions (correlation coefficient & efDot; 1). Preclinical education using a mixture of artificial saliva successfully quantified and visualized infectious areas and droplets, which revealed significant differences in ATP amounts in personal protective equipment among groups according to years of experience as dental practitioners (p < 0.05).
Conclusions An education system for infection control constructed using artificial saliva containing Lactobacillus and a UV-sensitive fluorescent hand lotion quantified the infectious areas and degrees. Thus, this method is effective in preclinical practice using dental phantoms. en-copyright= kn-copyright= en-aut-name=UedaAyaka en-aut-sei=Ueda en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=Takeuchi-HatanakaKazu en-aut-sei=Takeuchi-Hatanaka en-aut-mei=Kazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ItoTakashi en-aut-sei=Ito en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OnoShintaro en-aut-sei=Ono en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HiraiKimito en-aut-sei=Hirai en-aut-mei=Kimito 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=YamamotoTadashi en-aut-sei=Yamamoto en-aut-mei=Tadashi 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 Pathophysiology-Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathophysiology-Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Periodontics and Endodontics, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=4 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Pathophysiology-Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Pathophysiology-Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Pathophysiology-Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=The Center for Graduate Medical Education (Dental Division), Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Pathophysiology-Periodontal Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Dental education kn-keyword=Dental education en-keyword=Infection control kn-keyword=Infection control en-keyword=Fluorescent dye kn-keyword=Fluorescent dye en-keyword=Adenosine triphosphate kn-keyword=Adenosine triphosphate en-keyword=Lactobacillus kn-keyword=Lactobacillus END start-ver=1.4 cd-journal=joma no-vol=2025 cd-vols= no-issue=1 article-no= start-page=013C01 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Modification on Thermal Motion in Geant4 for Neutron Capture Simulation in Gadolinium Loaded Water en-subtitle= kn-subtitle= en-abstract= kn-abstract=Neutron tagging is a fundamental technique for electron anti-neutrino detection via the inverse beta decay channel.

By manually modifying the Geant4 implementation, the simulation results align with calculations based on evaluated nuclear data and show good agreement with observables derived from the SK-Gd data. en-copyright= kn-copyright= en-aut-name=HinoY. en-aut-sei=Hino en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AbeK. en-aut-sei=Abe en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AsakaR. en-aut-sei=Asaka en-aut-mei=R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HanS. en-aut-sei=Han en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HaradaM. en-aut-sei=Harada en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IshitsukaM. en-aut-sei=Ishitsuka en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ItoH. en-aut-sei=Ito en-aut-mei=H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IzumiyamaS. en-aut-sei=Izumiyama en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KanemuraY. en-aut-sei=Kanemura en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KoshioY. en-aut-sei=Koshio en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NakanishiF. en-aut-sei=Nakanishi en-aut-mei=F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=SekiyaH. en-aut-sei=Sekiya en-aut-mei=H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=YanoT. en-aut-sei=Yano en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Physics, Okayama University kn-affil= affil-num=2 en-affil=Kamioka Observatory, Institute for Cosmic Ray Research, University of Tokyo kn-affil= affil-num=3 en-affil=Department of Physics, Faculty of Science and Technology, Tokyo University of Science kn-affil= affil-num=4 en-affil=Research Center for Cosmic Neutrinos, Institute for Cosmic Ray Research, University of Tokyo kn-affil= affil-num=5 en-affil=Kamioka Observatory, Institute for Cosmic Ray Research, University of Tokyo kn-affil= affil-num=6 en-affil=Department of Physics, Faculty of Science and Technology, Tokyo University of Science kn-affil= affil-num=7 en-affil=Department of Physics, Faculty of Science and Technology, Tokyo University of Science kn-affil= affil-num=8 en-affil=Department of Physics, Tokyo Institute of Technology kn-affil= affil-num=9 en-affil=Kamioka Observatory, Institute for Cosmic Ray Research, University of Tokyo kn-affil= affil-num=10 en-affil=Department of Physics, Okayama University kn-affil= affil-num=11 en-affil=Department of Physics, Okayama University kn-affil= affil-num=12 en-affil=Kamioka Observatory, Institute for Cosmic Ray Research, University of Tokyo kn-affil= affil-num=13 en-affil=Kamioka Observatory, Institute for Cosmic Ray Research, University of Tokyo kn-affil= END start-ver=1.4 cd-journal=joma no-vol=172 cd-vols= no-issue=2 article-no= start-page=471 end-page=479 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250122 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Identification of factors related to functional prognoses in craniopharyngiomas en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Craniopharyngiomas are histologically benign tumors, but their proximity to vital neurovascular structures can significantly deteriorate functional prognoses and severely restrict patients’ social interaction and activity. We retrospectively identified risk factors related to the functional prognoses in patients with craniopharyngioma treated at our center.
Methods A retrospective analysis was conducted on 40 patients who underwent surgery for craniopharyngioma and follow-up at our institution between 2003 and 2022. Functional prognoses were evaluated in terms of obesity (body mass index [BMI]???25 for adults, BMI-Z???1.65 for children), visual function, endocrine function, and social participation. We investigated whether patient characteristics, tumor size, tumor location, hypothalamic involvement, surgical hypothalamic damage, extent of resection, and recurrence rate correlated with these functional prognostic factors.
Results The median age at diagnosis was 28.0 years, with a median follow-up of 80.5 months. Postoperative obesity was present in 22 patients, and those with postoperative obesity had a significantly higher preoperative BMI or BMI-Z (preoperative BMI for adults: p?=?0.074; preoperative BMI-Z for children: p?=?0.020) and were significantly correlated with preoperative hypothalamic involvement grade 2 (p?=?0.012) and surgical hypothalamic damage grade II (p?=?0.0001). Deterioration in social participation was significantly associated with a larger tumor size (p?=?0.023) and tumor recurrence (p?=?0.0047).
Conclusions Patients with higher preoperative BMI or BMI-Z and hypothalamic involvement have a greater risk of postoperative obesity, and larger tumor size and recurrence can significantly deteriorate the rate of patients’ social participation. en-copyright= kn-copyright= en-aut-name=UmedaTsuyoshi en-aut-sei=Umeda en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

We developed a virtual reality (VR) education system and evaluated its clinical utility for promoting hand hygiene practices.
Methods: This prospective, 2-week, randomized controlled study conducted at Okayama University Hospital, Japan, from November 2023 to January 2024, involved 22 participants (18 medical students and 4 residents). A fully immersive 360° VR system (VIVE Pro Eye) using a head-mounted display and sensing gloves was used to develop 3 health care tasks in a virtual patient room?Environmental Cleaning, Gauze Exchange, and Urine Collection. After monitoring all participants' baseline usage data of portable hand-rubbing alcohol in the first week, we randomly assigned them into 1:1 groups (VR training and video lecture groups). The primary outcome was differences in hand-rubbed alcohol use before and after intervention.
Results: Before the intervention, alcohol use did not significantly differ between both groups. After the intervention, a significant increase in alcohol use was observed in the VR training group (median: 8.2 g vs 16.2 g; P = .019) but not in the video lecture group.
Conclusions: Our immersive 360° VR education system enhanced hand hygiene practices. Infection prevention and control practitioners and digital technology experts must collaborate to advance the development of superior educational devices and content. en-copyright= kn-copyright= en-aut-name=IzumiMahiro en-aut-sei=Izumi en-aut-mei=Mahiro 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=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SoejimaYoshiaki en-aut-sei=Soejima en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShibataMitsunobu en-aut-sei=Shibata en-aut-mei=Mitsunobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HirotaSatoshi en-aut-sei=Hirota en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KoyamaToshihiro en-aut-sei=Koyama en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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=10 ORCID= affil-num=1 en-affil=Quality Assurance Center, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=6 en-affil=Quality Assurance Center, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=7 en-affil=Quality Assurance Center, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=8 en-affil=Department of Health Data Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Quality Assurance Center, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Infection prevention and control kn-keyword=Infection prevention and control en-keyword=Medical-engineering collaboration kn-keyword=Medical-engineering collaboration END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The perception of plastic waste and composition of boathouse waste in floating villages on Tonl? Sap Lake, Cambodia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Villagers living on Tonl? Sap (TS) Lake have low incomes and no access to basic public services, such as waste management, domestic water, electricity, and health care. Knowledge of the villagers’ perceptions and the composition of the waste from their boathouses will contribute to constructing a waste collection system with community participation within the framework of waste prevention and reduction. This study surveyed residents living in boathouses in four floating villages on TS Lake, Cambodia, regarding their perceptions and boathouse waste composition to assess the status of plastic waste and the villagers’ environmental awareness and their willingness to participate in waste collection. The household waste survey sought to clarify the amount of plastic waste and other recyclable waste discharged from floating houses. The perception survey revealed that in the wet season, 36% of respondents disposed of plastic waste by open burning/dumping and 40% by discharge into TS Lake; in the dry season, 76% disposed of waste by open burning/dumping, and only 4% discharged waste into TS Lake. An analysis of the boathouse plastic waste composition showed that residents of the floating villages generated 40.21 g plastic waste/day/capita, which was much lower than 340 g/day/capita in the USA, 120 g/day/capita in China, and even 70 g/day/capita in Cambodian on average, but higher than the 10 g/day/capita in India. This study proposes a novel and valuable framework to estimate and determine the level of awareness of people in floating villages related to plastic pollution effects and waste components from boathouses. At the same time, the research results provide an essential scientific basis to be able to develop an effective waste collection system in the area of TS Lake. The proposed framework of this study will help the policy decision-makers in the TS Lake area and those in similar geographical regions facing similar problems. en-copyright= kn-copyright= en-aut-name=Habuer en-aut-sei=Habuer en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiwaraTakeshi en-aut-sei=Fujiwara en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=VinSpoann en-aut-sei=Vin en-aut-mei=Spoann kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChandaraPhat en-aut-sei=Chandara en-aut-mei=Phat kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsukijiMakoto en-aut-sei=Tsukiji en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Environmental Management Course, Architecture, Civil Engineering and Environmental Management Program, School of Engineering, Okayama University kn-affil= affil-num=2 en-affil=Environmental Management Course, Architecture, Civil Engineering and Environmental Management Program, School of Engineering, Okayama University kn-affil= affil-num=3 en-affil=Department of Economic Development, Faculty of Development Studies, Royal University of Phnom Penh kn-affil= affil-num=4 en-affil=Department of Natural Resource Management and Development, Faculty of Development Studies, Royal University of Phnom Penh kn-affil= affil-num=5 en-affil=Environmental Management Course, Architecture, Civil Engineering and Environmental Management Program, School of Engineering, Okayama University kn-affil= en-keyword=Boathouse waste composition kn-keyword=Boathouse waste composition en-keyword=Cambodia kn-keyword=Cambodia en-keyword=Floating villages kn-keyword=Floating villages en-keyword=Perception survey kn-keyword=Perception survey en-keyword=Plastic waste kn-keyword=Plastic waste END start-ver=1.4 cd-journal=joma no-vol=58 cd-vols= no-issue= article-no= start-page=119 end-page=134 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Social Skills Required for Caregivers ――Outlook for Research Topics for Educational Practice―― kn-title=介護士に必要なソーシャルスキル――教育実践に向けた研究課題の展望―― en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MIYAKESayumi en-aut-sei=MIYAKE en-aut-mei=Sayumi kn-aut-name=三宅沙侑美 kn-aut-sei=三宅 kn-aut-mei=沙侑美 aut-affil-num=1 ORCID= en-aut-name=YAMANOYoichi en-aut-sei=YAMANO en-aut-mei=Yoichi kn-aut-name=山野洋一 kn-aut-sei=山野 kn-aut-mei=洋一 aut-affil-num=2 ORCID= en-aut-name=TANAKATomoko en-aut-sei=TANAKA en-aut-mei=Tomoko kn-aut-name=田中共子 kn-aut-sei=田中 kn-aut-mei=共子 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院社会文化科学研究科 affil-num=2 en-affil= kn-affil=京都産業大学　教育支援研究開発センター affil-num=3 en-affil= kn-affil=岡山大学社会文化科学学域 END start-ver=1.4 cd-journal=joma no-vol=58 cd-vols= no-issue= article-no= start-page=71 end-page=89 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Exploring the Link Between Modern Household Amenities and Health in Vietnam en-subtitle= kn-subtitle= en-abstract= kn-abstract=　The correlation between the impact of the external and internal environment of a household on its occupants’ health has been well documented by various research studies. Yet a limitation of the literature is the prevalence of modern household basic amenities and occupant health, especially in Vietnam. This paper examines the impact of modern household basic amenities on occupant health by applying the Vietnam Household Standard Survey 2018. By applying the Tobit method, it is revealed that household amenities displayed a significant association with health outcomes. For instance, individuals residing in concrete houses or employing waste collection systems exhibited decreased illness likelihood. Handwashing with soap correlated with a diminished illness probability. Tobit analysis highlights internet accessibility as significant in reducing days of work incapacity (approximately 6 days less). Gender, residential location, and total income also impact workdays. Age and education exhibit inverse relationships with workdays missed. In essence, these findings contribute to the broader discourse on public health and underscore the importance of considering diverse factors, ranging from basic amenities to socio-economic indicators, in formulating comprehensive health policies and interventions. en-copyright= kn-copyright= en-aut-name=Do Thi Hoai Giang en-aut-sei=Do Thi Hoai Giang en-aut-mei= kn-aut-name=ド ティ ホアイ ジャン kn-aut-sei=ド ティ ホアイ ジャン kn-aut-mei= 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=Modern household amenity kn-keyword=Modern household amenity en-keyword=occupant health kn-keyword=occupant health en-keyword=Vietnam kn-keyword=Vietnam en-keyword=Tobit regression kn-keyword=Tobit regression en-keyword=Logit model kn-keyword=Logit model END start-ver=1.4 cd-journal=joma no-vol=741 cd-vols= no-issue= article-no= start-page=151006 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=S-adenosylmethionine and S-adenosyl-L-homocysteine metabolism is involved in the sperm motility and in vitro fertility rate in mouse en-subtitle= kn-subtitle= en-abstract= kn-abstract=Increased fragmentation of sperm DNA has been implicated in male infertility. Folate deficiency results in impaired methionine synthesis, depletion of S-adenosylmethionine (SAM) levels, an increase in S-adenosyl-l-homocysteine (SAH) levels, and increased DNA fragmentation. Disruption of the dynamic balance between SAM and SAH may also contribute, although the details of this process are not yet fully understood. We investigated the localization of SAM, SAH, and S-adenosylhomocysteine hydrolase (SAHH), and whether SAM/SAH metabolism contributes to sperm motility and fertilization rate. SAM, SAH, and SAHH levels were assessed in the acrosome, midpiece, and tail of spermatozoa. Chemical inhibition of SAM/SAH metabolism and extracellular SAH significantly decreased the straight-line velocity (VSL), curvilinear velocity (VCL), and amplitude lateral head displacement (ALH) of sperm cells, which were thus unable to swim forward and perform oscillatory movements in place. This significantly reduced the fertilization rate. Therefore, the disruption of the SAM/SAH balance may contribute to male infertility. en-copyright= kn-copyright= en-aut-name=KawaiTomoko en-aut-sei=Kawai en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujimuraAtsushi en-aut-sei=Fujimura en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=SAM/SAH metabolism kn-keyword=SAM/SAH metabolism en-keyword=Sperm motility kn-keyword=Sperm motility en-keyword=Fertilization rate kn-keyword=Fertilization rate END start-ver=1.4 cd-journal=joma no-vol=125 cd-vols= no-issue= article-no= start-page=106672 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=Resveratrol, a food-derived polyphenol, promotes Melanosomal degradation in skin fibroblasts through coordinated activation of autophagy, lysosomal, and antioxidant pathways en-subtitle= kn-subtitle= en-abstract= kn-abstract=Resveratrol, a polyphenol found in grapes and peanuts, is known for diverse biological activities, yet its effects on dermal hyperpigmentation (so-called dark spots) remain unexplored. We investigated resveratrol's ability to enhance melanosomal degradation in human dermal fibroblasts. At concentrations of 25-50 mu M, resveratrol increased autophagy as measured by microtubule-associated protein 1A/1B-light chain 3 (LC3)-II/LC3-I ratio and enhanced lysosomal activity as assessed by a lysosomal activity reporter system. RNA sequencing revealed upregulation of lysosomal and autophagy-related genes, including cathepsins. Furthermore, reporter assays showed resveratrol's activation of antioxidant response via nuclear factor erythroid 2-related factor 2 (NRF2)mediated, leading to upregulation of transcription factor EB/transcription factor E3 (TFEB/TFE3), master regulators of lysosomal function. In fibroblasts pre-loaded with melanosomes, resveratrol reduced melanosome content compared to control by day 3. The findings reveal the activation of interconnected autophagy, lysosomal, and antioxidant pathways by resveratrol, suggesting potential applications in functional foods targeting dermal hyperpigmentation. en-copyright= kn-copyright= en-aut-name=OkamotoSaki en-aut-sei=Okamoto en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KakimaruSaya en-aut-sei=Kakimaru en-aut-mei=Saya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KoreishiMayuko en-aut-sei=Koreishi en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakamotoMika en-aut-sei=Sakamoto en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=AndoHideya en-aut-sei=Ando en-aut-mei=Hideya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsujinoYoshio en-aut-sei=Tsujino en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SatohAyano en-aut-sei=Satoh en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=National Institute of Genetics, ROIS kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Department of Applied Chemistry and Biotechnology, Okayama University of Science kn-affil= affil-num=7 en-affil=Graduate School of Science, Technology, and Innovation, Kobe University kn-affil= affil-num=8 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Antioxidant kn-keyword=Antioxidant en-keyword=Lysosomes kn-keyword=Lysosomes en-keyword=Autophagy kn-keyword=Autophagy en-keyword=Resveratrol kn-keyword=Resveratrol en-keyword=Skin fibroblasts kn-keyword=Skin fibroblasts en-keyword=Bioactive compounds kn-keyword=Bioactive compounds END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=39 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250109 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness of professional-identity-formation and clinical communication-skills programs on medical students' empathy in the COVID-19 context: comparison between pre-pandemic in-person classes and during-pandemic online classes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Enhancing students' empathy is critical in medical school education. The COVID-19 pandemic necessitated a shift from in-person to online classes. However, the effectiveness of online classes for enhancing medical students' empathy has not been investigated sufficiently and the evidence is limited. This study compared the effectiveness of enhancing empathy between pre-pandemic in-person classes and during-pandemic online classes among medical students in Japan using pre-pandemic and during-pandemic data.
Methods This is a retrospective observational study. This study measured students' empathy using the Japanese translation of the Jefferson Scale of Empathy-Student Version (JSE-S) before and after the special programs for professional identity formation and clinical communication among first- and second-year students who matriculated from 2015-2021. This study categorized the matriculation year groups as "pre-pandemic" and "during-pandemic" groups for the first- and second-year students. This study estimated the adjusted mean score differences of the JSE-S and 95% confidence intervals (CIs) from the pre- to post-program between the pre-pandemic and during-pandemic groups in the first and second years using linear regression analysis.
Results This study's participants included 653 first-year students and 562 second-year students. In the first year, the during-pandemic group had a significantly higher mean score difference from the pre- to post-program compared to the pre-pandemic group. The adjusted regression coefficient (95% CI) was 7.6 (5.7 - 9.5), with the pre-pandemic group as the reference. In the second year, there were no significant differences between the two groups.
Conclusions The results suggest that online classes are not inferior to in-person classes or even slightly better in enhancing medical students' empathy, which should be clarified by further studies. This study's findings have important implications for medical education and implementing hybrid class formats to enhance students' empathy. en-copyright= kn-copyright= en-aut-name=KataokaHitomi en-aut-sei=Kataoka en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TokinobuAkiko en-aut-sei=Tokinobu en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiChikako en-aut-sei=Fujii en-aut-mei=Chikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeMayu en-aut-sei=Watanabe en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ObikaMikako en-aut-sei=Obika en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Center for Diversity and Inclusion, Okayama University Hospital kn-affil= affil-num=2 en-affil=Center for Diversity and Inclusion, Okayama University Hospital kn-affil= affil-num=3 en-affil=Center for Diversity and Inclusion, Okayama University Hospital kn-affil= affil-num=4 en-affil=Division of Kidney, Diabetes and Endocrine Diseases, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of General Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=COVID-19 pandemic kn-keyword=COVID-19 pandemic en-keyword=Empathy kn-keyword=Empathy en-keyword=Jefferson Scale of Empathy kn-keyword=Jefferson Scale of Empathy en-keyword=Medical students kn-keyword=Medical students en-keyword=Online class kn-keyword=Online class END start-ver=1.4 cd-journal=joma no-vol=126 cd-vols= no-issue=1 article-no= start-page=012901 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250102 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dynamic domain motion enhancing electro-optic performance in ferroelectric films en-subtitle= kn-subtitle= en-abstract= kn-abstract=With the rapid advancement of information technology, there is a pressing need to develop ultracompact and energy-efficient thin-film-based electro-optic (EO) devices. A high EO coefficient in ferroelectric materials is crucial. However, substrate clamping can positively or negatively influence various physical properties, including the EO response of these films, thus complicating the development of next-generation thin-film-based devices. This study demonstrates that reversible dynamic domain motion, achieved through substrate clamping, significantly enhances the EO coefficient in epitaxial ferroelectric rhombohedral Pb(Zr, Ti)O3 thin films, where the (111) and (? 111?) domains coexist with distinct optical axes. In principle, this approach can be applied to different film-substrate systems, thereby contributing to the advancement of sophisticated EO devices based on ferroelectrics. en-copyright= kn-copyright= en-aut-name=KondoShinya en-aut-sei=Kondo en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkamotoKazuki en-aut-sei=Okamoto en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakataOsami en-aut-sei=Sakata en-aut-mei=Osami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=KishimotoAkira en-aut-sei=Kishimoto en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NagasakiTakanori en-aut-sei=Nagasaki en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamadaTomoaki en-aut-sei=Yamada en-aut-mei=Tomoaki 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=Department of Energy Engineering, Nagoya University kn-affil= affil-num=3 en-affil=Japan Synchrotron Radiation Research Institute (JASRI) 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=Department of Energy Engineering, Nagoya University kn-affil= affil-num=7 en-affil=Department of Energy Engineering, Nagoya University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=52 article-no= start-page=35202 end-page=35213 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241216 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bright Quantum-Grade Fluorescent Nanodiamonds en-subtitle= kn-subtitle= en-abstract= kn-abstract=Optically accessible spin-active nanomaterials are promising as quantum nanosensors for probing biological samples. However, achieving bioimaging-level brightness and high-quality spin properties for these materials is challenging and hinders their application in quantum biosensing. Here, we demonstrate bright fluorescent nanodiamonds (NDs) containing 0.6?1.3-ppm negatively charged nitrogen-vacancy (NV) centers by spin-environment engineering via enriching spin-less 12C-carbon isotopes and reducing substitutional nitrogen spin impurities. The NDs, readily introduced into cultured cells, exhibited improved optically detected magnetic resonance (ODMR) spectra; peak splitting (E) was reduced by 2?3 MHz, and microwave excitation power required was 20 times lower to achieve a 3% ODMR contrast, comparable to that of conventional type-Ib NDs. They show average spin-relaxation times of T1 = 0.68 ms and T2 = 3.2 μs (1.6 ms and 5.4 μs maximum) that were 5- and 11-fold longer than those of type-Ib, respectively. Additionally, the extended T2 relaxation times of these NDs enable shot-noise-limited temperature measurements with a sensitivity of approximately 0.28K/√Hz. The combination of bulk-like NV spin properties and enhanced fluorescence significantly improves the sensitivity of ND-based quantum sensors for biological applications. en-copyright= kn-copyright= en-aut-name=OshimiKeisuke en-aut-sei=Oshimi en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshiwataHitoshi en-aut-sei=Ishiwata en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakashimaHiromu en-aut-sei=Nakashima en-aut-mei=Hiromu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Mandi?Sara en-aut-sei=Mandi? en-aut-mei=Sara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobayashiHina en-aut-sei=Kobayashi en-aut-mei=Hina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TeramotoMinori en-aut-sei=Teramoto en-aut-mei=Minori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsujiHirokazu en-aut-sei=Tsuji en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishibayashiYoshiki en-aut-sei=Nishibayashi en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShikanoYutaka en-aut-sei=Shikano en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AnToshu en-aut-sei=An en-aut-mei=Toshu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FujiwaraMasazumi en-aut-sei=Fujiwara en-aut-mei=Masazumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Chemistry, Graduate School of Life, Environmental, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=The National Institutes for Quantum Science and Technology (QST), Institute for Quantum Life Science (iQLS) kn-affil= affil-num=3 en-affil=Department of Chemistry, Graduate School of Life, Environmental, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Chemistry, Graduate School of Life, Environmental, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Department of Chemistry, Graduate School of Life, Environmental, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Advanced Materials Laboratory, Sumitomo Electric Industries, Ltd. kn-affil= affil-num=7 en-affil=Advanced Materials Laboratory, Sumitomo Electric Industries, Ltd. kn-affil= affil-num=8 en-affil=Advanced Materials Laboratory, Sumitomo Electric Industries, Ltd. kn-affil= affil-num=9 en-affil=Institute of Systems and Information Engineering, University of Tsukuba kn-affil= affil-num=10 en-affil=School of Materials Science, Japan Advanced Institute of Science and Technology kn-affil= affil-num=11 en-affil=Department of Chemistry, Graduate School of Life, Environmental, Natural Science and Technology, Okayama University kn-affil= en-keyword=nanodiamonds kn-keyword=nanodiamonds en-keyword=nitrogen-vacancy centers kn-keyword=nitrogen-vacancy centers en-keyword=spins kn-keyword=spins en-keyword=spin-relaxation times kn-keyword=spin-relaxation times en-keyword=quantum biosensor kn-keyword=quantum biosensor en-keyword=cellular probes kn-keyword=cellular probes END start-ver=1.4 cd-journal=joma no-vol=2024 cd-vols= no-issue=12 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Multi-dimensional optimisation of the scanning strategy for the LiteBIRD space mission en-subtitle= kn-subtitle= en-abstract= kn-abstract=Large angular scale surveys in the absence of atmosphere are essential for measuring the primordial B-mode power spectrum of the Cosmic Microwave Background (CMB). Since this proposed measurement is about three to four orders of magnitude fainter than the temperature anisotropies of the CMB, in-flight calibration of the instruments and active suppression of systematic effects are crucial. We investigate the effect of changing the parameters of the scanning strategy on the in-flight calibration effectiveness, the suppression of the systematic effects themselves, and the ability to distinguish systematic effects by null-tests. Next-generation missions such as LiteBIRD, modulated by a Half-Wave Plate (HWP), will be able to observe polarisation using a single detector, eliminating the need to combine several detectors to measure polarisation, as done in many previous experiments and hence avoiding the consequent systematic effects. While the HWP is expected to suppress many systematic effects, some of them will remain. We use an analytical approach to comprehensively address the mitigation of these systematic effects and identify the characteristics of scanning strategies that are the most effective for implementing a variety of calibration strategies in the multi-dimensional space of common spacecraft scan parameters. We verify that LiteBIRD's standard configuration yields good performance on the metrics we studied. We also present Falcons.jl, a fast spacecraft scanning simulator that we developed to investigate this scanning parameter space. en-copyright= kn-copyright= en-aut-name=TakaseY. en-aut-sei=Takase

Such emergency indicates that cholera toxin-producing Vibrio cholerae O1 (toxigenic V. cholerae O1) are widespread in Kolkata. This suggests that the suitable conditions for replication of toxigenic V. cholerae O1 is provided in Kolkata. In previous studies, we found that the replication rate of toxigenic V. cholerae O1 is low in the low ionic aqueous solution. Then we measured the ion concentration in the environmental water of Kolkata. As a control, we measured them in Japanese environmental water. The ion concentration in the environmental water of Kolkata was significantly high. Then, we examined the survival of toxigenic V. cholerae O1 in groundwater from Kolkata and found that V. cholerae O1 survive for long time in the solution but not in the solution diluted with Milli Q water. In addition, we found that V. cholerae O1 proliferated in environmental water of Kolkata to which a small amount of nutrient was added, but did not grow in the environmental water diluted with water to which the same amount of nutrient was added. These results indicate that the environmental water from Kolkata is suitable for survival of V. cholerae O1. en-copyright= kn-copyright= en-aut-name=TakahashiEizo en-aut-sei=Takahashi en-aut-mei=Eizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitaharaKei en-aut-sei=Kitahara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChowdhuryGoutam en-aut-sei=Chowdhury en-aut-mei=Goutam kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MukhopadhyayAsish K. en-aut-sei=Mukhopadhyay en-aut-mei=Asish K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DuttaShanta en-aut-sei=Dutta en-aut-mei=Shanta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OchiSadayuki en-aut-sei=Ochi en-aut-mei=Sadayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkamotoKeinosuke en-aut-sei=Okamoto en-aut-mei=Keinosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Collaborative Research Center of Okayama University for Infectious Diseases in India kn-affil= affil-num=2 en-affil=Collaborative Research Center of Okayama University for Infectious Diseases in India kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences of Okayama University kn-affil= affil-num=4 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=5 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=6 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=7 en-affil=Department of Health Pharmacy, Yokohama University of Pharmacy kn-affil= affil-num=8 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences of Okayama University kn-affil= en-keyword=Environmental water kn-keyword=Environmental water en-keyword=Ion kn-keyword=Ion en-keyword=Prevalence kn-keyword=Prevalence en-keyword=Survival kn-keyword=Survival en-keyword=Vibrio cholerae kn-keyword=Vibrio cholerae END
