Although there have been many studies on the drying behavior of a single-component slurry droplet, there have been few reports for a multicomponent slurry droplet. This is due to the complexity and difficulty in evaluating the drying behavior of a multicomponent slurry droplet. Therefore, for the production of granules from multicomponent materials by a spray dryer, its operating conditions are usually determined by trial and error. To optimize the practical granule production process, the drying behavior of multicomponent slurry droplets should be studied. In this study, the drying behavior of a silica slurry droplet containing polyvinyl alcohol (PVA) is investigated. The drying behavior of a droplet suspended on the tip of a needle was observed. The effect of the volume fraction of PVA on the drying behavior and the morphology of a dried granule is studied. The effect of drying condition on the granule formation process is also investigated. As a result, the structure of dried granules was strongly influenced by PVA concentration. Segregation of PVA in the dried granules was observed. Based on the results, the drying process diagram is presented. en-copyright= kn-copyright= en-aut-name=NakasoKoichi en-aut-sei=Nakaso en-aut-mei=Koichi kn-aut-name=’†‘]_ˆê kn-aut-sei=’†‘] kn-aut-mei=_ˆê aut-affil-num=1 ORCID= en-aut-name=YamashitaDaichi en-aut-sei=Yamashita en-aut-mei=Daichi kn-aut-name=ŽR‰º‘å’q kn-aut-sei=ŽR‰º kn-aut-mei=‘å’q aut-affil-num=2 ORCID= en-aut-name=AoyamaYutaro en-aut-sei=Aoyama en-aut-mei=Yutaro kn-aut-name=ÂŽR—S‘¾˜Y kn-aut-sei=ÂŽR kn-aut-mei=—S‘¾˜Y aut-affil-num=3 ORCID= en-aut-name=MinoYasushi en-aut-sei=Mino en-aut-mei=Yasushi kn-aut-name=ŽO–ì‘׎u kn-aut-sei=ŽO–ì kn-aut-mei=‘׎u aut-affil-num=4 ORCID= en-aut-name=GotohKuniaki en-aut-sei=Gotoh en-aut-mei=Kuniaki kn-aut-name=Œã“¡–M² kn-aut-sei=Œã“¡ kn-aut-mei=–M² aut-affil-num=5 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=‰ªŽR‘åŠwŠwpŒ¤‹†‰@ŠÂ‹«¶–½Ž©‘R‰ÈŠwŠwˆæ affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=‰ªŽR‘åŠw‘åŠw‰@Ž©‘R‰ÈŠwŒ¤‹†‰È affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=‰ªŽR‘åŠw‘åŠw‰@Ž©‘R‰ÈŠwŒ¤‹†‰È affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=‰ªŽR‘åŠwŠwpŒ¤‹†‰@ŠÂ‹«¶–½Ž©‘R‰ÈŠwŠwˆæ affil-num=5 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=‰ªŽR‘åŠwŠwpŒ¤‹†‰@ŠÂ‹«¶–½Ž©‘R‰ÈŠwŠwˆæ en-keyword=Spray Dryer kn-keyword=Spray Dryer en-keyword=Drying kn-keyword=Drying en-keyword=Droplet kn-keyword=Droplet en-keyword=Slurry kn-keyword=Slurry en-keyword=Water-Soluble Polymer kn-keyword=Water-Soluble Polymer 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=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=One-pot synthesis of trans-2,3-diaminoindolines through 2,3-diamination of electrophilic indolines en-subtitle= kn-subtitle= en-abstract= kn-abstract=Despite recent advances in the synthesis of 2,3-diaminoindole derivatives, construction of 2,3-diaminoindolines, whose two amine moieties on each molecule differ from one another has yet to be achieved.

Furthermore, the synthetic utility of this protocol was demonstrated by a successful gram-scale reaction and further transformation of the 2,3-diaminoindolines. en-copyright= kn-copyright= en-aut-name=KoboriYuito en-aut-sei=Kobori en-aut-mei=Yuito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TokushigeKeisuke en-aut-sei=Tokushige en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AbeTakumi en-aut-sei=Abe en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e202510319 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250626 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of a Vinylated Cyclic Allene: A Fleeting Strained Diene for the Diels?Alder Reaction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fleeting molecules possessing strained multiple bonds are important components in organic synthesis due to their ability to undergo various chemical reactions driven by the release of strain energy. Although the use of strained ƒÎ-bonds as 2ƒÎ components, represented by dienophiles in Diels?Alder reactions, has been well studied, gthe strained diene (4ƒÎ component) approachh for molecular construction remains underexplored. Herein, we report the design of a vinyl cyclic allene (1-vinyl-1,2-cyclohexadiene) as a highly reactive strained diene and the development of its Diels?Alder reactions. Experimental and computational studies of vinyl cyclic allenes revealed that this diene system undergoes cycloaddition with dienophiles regio- and stereoselectively under mild reaction conditions. These studies also provide insight into the reactivity and selectivity of the system. The strained diene approach enables the convergent construction of polycyclic molecules through bond disconnections distinct from conventional retrosynthetic analysis, thus offering an efficient strategy for the assembly of functional molecules. en-copyright= kn-copyright= en-aut-name=MizoguchiHaruki en-aut-sei=Mizoguchi en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ObataTakumi en-aut-sei=Obata en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiraiTaiki en-aut-sei=Hirai en-aut-mei=Taiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KomatsuManaka en-aut-sei=Komatsu en-aut-mei=Manaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakakuraAkira en-aut-sei=Sakakura en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=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= en-keyword=Activation strain model kn-keyword=Activation strain model en-keyword=Carbocycles kn-keyword=Carbocycles en-keyword=Diels?Alder reaction kn-keyword=Diels?Alder reaction en-keyword=Strained diene kn-keyword=Strained diene en-keyword=Vinylated cyclic allene kn-keyword=Vinylated cyclic allene 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=20250224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Towards SBOM-based Access Control for Transparent and Explicit Program Execution en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although a Software Bill of Materials (SBOM) plays a key role in software transparency, inconsistencies in SBOM descriptions can undermine its value.

In this study, we identify the challenges associated with implementing this approach and present preliminary investigation results to address these challenges. en-copyright= kn-copyright= en-aut-name=ShimamotoYuta en-aut-sei=Shimamoto en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UekawaHiroyuki en-aut-sei=Uekawa en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AkiyamaMitsuaki en-aut-sei=Akiyama en-aut-mei=Mitsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=NTT Social Informatics Laboratories kn-affil= affil-num=3 en-affil=NTT Social Informatics Laboratories kn-affil= affil-num=4 en-affil=Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=91 cd-vols= no-issue=946 article-no= start-page=24-00128 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=Development of a guideline proposal system for correcting cutting conditions based on the overhang length of ball end-mills kn-title=ƒ{[ƒ‹ƒGƒ“ƒhƒ~ƒ‹‚Ì“Ë‚«o‚µ’·‚³‚ɉž‚¶‚½ØíðŒ•â³ƒVƒXƒeƒ€‚ÌŠJ”­ en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the field of die and mold machining, determining appropriate cutting conditions is crucial. Factors such as tool geometry, machining path, work material characteristics, machining efficiency, and finishing accuracy must be taken into consideration. However, the current method of determining cutting conditions relies heavily on the intuition and experience of skilled engineers, and there is a need for a system to replace such knowledge. One of the critical factors affecting machining accuracy and efficiency is the tool overhang length, which is directly related to tool geometry. Unfortunately, there is no clear guideline for its determination. In a previous study, researchers developed a system to quickly derive cutting conditions using a data mining method and Random Forest Regression (RFR) applied to a tool catalog database. In this study, we constructed a new cutting condition compensation system based on the existing model, which accounts for the tool overhang length. The results of cutting experiments under high aspect ratio overhang lengths confirm that the correction coefficients proposed by the system are significant. en-copyright= kn-copyright= en-aut-name=KODAMAHiroyuki en-aut-sei=KODAMA en-aut-mei=Hiroyuki kn-aut-name=Ž™‹ÊhK kn-aut-sei=Ž™‹Ê kn-aut-mei=hK aut-affil-num=1 ORCID= en-aut-name=MORIYAYuki en-aut-sei=MORIYA en-aut-mei=Yuki kn-aut-name=Žç‰®—S‹P kn-aut-sei=Žç‰® kn-aut-mei=—S‹P aut-affil-num=2 ORCID= en-aut-name=MORIMOTOTatsuo en-aut-sei=MORIMOTO en-aut-mei=Tatsuo kn-aut-name=·Œ³’B—Y kn-aut-sei=·Œ³ kn-aut-mei=’B—Y aut-affil-num=3 ORCID= en-aut-name=OHASHIKazuhito en-aut-sei=OHASHI en-aut-mei=Kazuhito kn-aut-name=‘å‹´ˆêm kn-aut-sei=‘å‹´ kn-aut-mei=ˆêm aut-affil-num=4 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=‰ªŽR‘åŠw ŠwpŒ¤‹†‰@ŠÂ‹«¶–½Ž©‘R‰ÈŠwŠwˆæ affil-num=2 en-affil=Graduate school of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=‰ªŽR‘åŠw ‘åŠw‰@ŠÂ‹«¶–½Ž©‘R‰ÈŠwŒ¤‹†‰È affil-num=3 en-affil=Graduate school of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=‰ªŽR‘åŠw ‘åŠw‰@ŠÂ‹«¶–½Ž©‘R‰ÈŠwŒ¤‹†‰È affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=‰ªŽR‘åŠw ŠwpŒ¤‹†‰@ŠÂ‹«¶–½Ž©‘R‰ÈŠwŠwˆæ en-keyword=Data mining kn-keyword=Data mining en-keyword=Cutting conditions kn-keyword=Cutting conditions en-keyword=Machine learning kn-keyword=Machine learning en-keyword=Random Forest Regression kn-keyword=Random Forest Regression en-keyword=Ball end-mill kn-keyword=Ball end-mill en-keyword=Tool overhang length kn-keyword=Tool overhang length END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=3 article-no= start-page=337 end-page=345 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Study on the Grinding Temperature of Workpiece in Side Plunge Grinding Process en-subtitle= kn-subtitle= en-abstract= kn-abstract=Grinding is used to finish thrust metal attachment parts, such as crankshafts, which have both journal and thrust surfaces. In side plunge grinding, a thrust surface and a cylindrical surface of a shaft workpiece with collars are finished in a single plunge grinding process. However, the surface quality near the ground internal corner, where grinding fluid may not penetrate, can deteriorate, causing high residual stress and cracks owing to grinding heat. While it has been reported that quality issues at the inner corners of the ground surface can be mitigated by reducing the grinding point temperature through efficient cooling fluid supply, the mechanisms of grinding phenomena and heat generation in side plunge grinding are not yet fully understood. In this study, the variations in the grinding temperature at the thrust surface of a workpiece with a collar were experimentally investigated using a wire/workpiece thermocouple to clarify these phenomena. The results revealed a significant increase in the grinding temperature at the corners of the grinding zone. However, it slightly decreases as the thermocouple output approaches the center of the workpiece, indicating a slight effect of the grinding speed. The surface temperature of the workpiece in side plunge grinding is primarily influenced by the wheel depth-of-cut in the thrust direction. Additionally, the effect of workpiece rotational speed and grinding infeed speed on temperature distribution has been demonstrated. en-copyright= kn-copyright= en-aut-name=GaoLingxiao en-aut-sei=Gao en-aut-mei=Lingxiao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuidaMotoki en-aut-sei=Kuida en-aut-mei=Motoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KodamaHiroyuki en-aut-sei=Kodama en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OhashiKazuhito en-aut-sei=Ohashi en-aut-mei=Kazuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=grinding kn-keyword=grinding en-keyword=thrust surface kn-keyword=thrust surface en-keyword=grinding temperature kn-keyword=grinding temperature en-keyword=thermocouple kn-keyword=thermocouple END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=85 end-page=104 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220812 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=CyNER: Information Extraction from?Unstructured Text of?CTI Sources with?Noncontextual IOCs en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cybersecurity threats have been increasing and growing more sophisticated year by year. In such circumstances, gathering Cyber Threat Intelligence (CTI) and following up with up-to-date threat information is crucial. Structured CTI such as Structured Threat Information eXpression (STIX) is particularly useful because it can automate security operations such as updating FW/IDS rules and analyzing attack trends. However, as most CTIs are written in natural language, manual analysis with domain knowledge is required, which becomes quite time-consuming.
In this work, we propose CyNER, a method for automatically structuring CTIs and converting them into STIX format. CyNER extracts named entities in the context of CTI and then extracts the relations between named entities and IOCs in order to convert them into STIX. In addition, by using key phrase extraction, CyNER can extract relations between IOCs that lack contextual information, such as those listed at the bottom of a CTI, and named entities. We describe our design and implementation of CyNER and demonstrate that it can extract named entities with the F-measure of 0.80 and extract relations between named entities and IOCs with the maximum accuracy of 81.6%. Our analysis of structured CTI showed that CyNER can extract IOCs that are not included in existing reputation sites, and that it can automatically extract IOCs that have been exploited for a long time and across multiple attack groups. CyNER is thus expected to contribute to the efficiency of CTI analysis. en-copyright= kn-copyright= en-aut-name=FujiiShota en-aut-sei=Fujii en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawaguchiNobutaka en-aut-sei=Kawaguchi en-aut-mei=Nobutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShigemotoTomohiro en-aut-sei=Shigemoto en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Research & Development Group, Hitachi, Ltd. kn-affil= affil-num=3 en-affil=Research & Development Group, Hitachi, Ltd. kn-affil= affil-num=4 en-affil=Faculty of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=292 end-page=297 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Analyzing Post-injection Attacker Activities in IoT Devices: A Comprehensive Log Analysis Approach en-subtitle= kn-subtitle= en-abstract= kn-abstract=With the continuous proliferation of Internet of Things (IoT) devices, malware threats that specifically target these devices continue to increase. The urgent need for robust security measures is predicated on a comprehensive understanding of the behavioral patterns of IoT malware. However, previous studies have often overlooked the analysis of command sequences in Telnet logs. This study bridges this research gap by examining the post-injection behaviors of attackers. By analyzing a vast dataset comprising more than ten million logs collected from an IoT honeypot, we reveal three distinct post-injection activity patterns, each with unique characteristics. These patterns provide pivotal insights that not only help distinguish between legitimate operations and attempted attacks, but also drive the development of robust cybersecurity measures that effectively deter such behaviors. The nuances discovered in this study contribute significantly to IoT security by enhancing our understanding of malware tactics and informing targeted defense strategies. en-copyright= kn-copyright= en-aut-name=VictorHervet en-aut-sei=Victor en-aut-mei=Hervet kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobayashiSatoru en-aut-sei=Kobayashi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Malware analysis kn-keyword=Malware analysis en-keyword=IoT kn-keyword=IoT en-keyword=Honeypot kn-keyword=Honeypot en-keyword=Log analysis kn-keyword=Log analysis en-keyword=Attack patterns kn-keyword=Attack patterns END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=274 end-page=278 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prevention Method for Stack Buffer Overflow Attack in TA Command Calls in OP-TEE en-subtitle= kn-subtitle= en-abstract= kn-abstract=TEE systems provide normal world and secure world.

They exploit the latest vulnerabilities discovered in IoT devices. Therefore, Mandatory Access Control (MAC) systems based on Linux Security Modules (LSM), such as SELinux and AppArmor, are effective security features for IoT devices because they can mitigate the impact of attacks even if software vulnerabilities are discovered. However, they are not adopted by most IoT devices. The existing approaches are insufficient for investigating the causes of this problem.In this study, we comprehensively investigated what factors can affect the applicability of MAC systems based on LSM in IoT devices. We focused on how frequently cases can occur where they cannot be adopted, owing to each factor. To increase the comprehensiveness of the factors affecting the adoption of MAC systems in IoT devices, we investigated the kernel version, CPU architecture, and support for BusyBox in addition to the investigation of resources, which conducted in previous studies. We also conducted simulated experiments based on the attack method of Mirai to investigate whether MAC systems can protect against IoT malware. Finally, we discuss the impact of a combination of these factors on MAC system adoption. en-copyright= kn-copyright= en-aut-name=MikiMasato en-aut-sei=Miki en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KobayashiSatoru en-aut-sei=Kobayashi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Mandatory Access Control System kn-keyword=Mandatory Access Control System en-keyword=IoT Security kn-keyword=IoT Security en-keyword=Linux Security Modules kn-keyword=Linux Security Modules END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=236 end-page=244 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230623 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Non Real-Time Data Transmission Performance Analysis of PROFINET for Assuring Data Transmission Quality en-subtitle= kn-subtitle= en-abstract= kn-abstract=The industrial Ethernet PROFINET supports three different data transmission modes: isochronous real-time (IRT), real-time (RT), and non real-time (NRT) transmitting data requiring hard, soft, and no real-time performances, respectively. The data transmission latency in the NRT increased with the amount of data transmission in the IRT, RT, and NRT. Therefore, the quality of data transmission in NRT may degrade as the amount of data transmission in IRT, RT, and NRT increases. In this study, we derived the average data transmission latency in an NRT with data transmission in IRT and RT by applying stochastic processes. This allowed us to maintain the quality of data transmission in the NRT by adjusting the number of devices connected to the network and the number of applications transmitting data in the NRT so that the average latency of data in the NRT does not exceed a certain value. en-copyright= kn-copyright= en-aut-name=NorimatsuTakashi en-aut-sei=Norimatsu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Industrial Ethernet kn-keyword=Industrial Ethernet en-keyword=PROFINET kn-keyword=PROFINET en-keyword=Non Real Time kn-keyword=Non Real Time en-keyword=Real-Time kn-keyword=Real-Time en-keyword=Isochronous Real Time kn-keyword=Isochronous Real Time END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=267 end-page=273 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Supporting Multiple OS Types on Estimation of System Call Hook Point by Virtual Machine Monitor en-subtitle= kn-subtitle= en-abstract= kn-abstract=Methods to hook system calls issued by a guest operating system (OS) running on a virtual machine using a virtual machine monitor are proposed. The address of the hook point is derived from the guest OSfs source code and established prior to the kernel startup process. Due to changes in system call processing in OS updates and address space layout randomization, the addresses of these hook points cannot always be pre-determined before the kernel startup process. To address this challenge, a method for estimating the system call hook point is proposed in Linux by analyzing the guest OS memory on x86-64 CPUs rather than pre-calculation. Although the method supports Linux, the method can be extended to support other OS types. In this paper, we propose a method to extend the method to support additional OSes. Specifically, we present analysis results and a novel method for estimating hook points on FreeBSD, NetBSD, and OpenBSD. The effectiveness of our proposed method is also demonstrated through evaluation. en-copyright= kn-copyright= en-aut-name=SatoMasaya en-aut-sei=Sato en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OmoriTaku en-aut-sei=Omori en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TaniguchiHideo en-aut-sei=Taniguchi en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Okayama Prefectural University kn-affil= affil-num=2 en-affil=Okayama Prefectural University kn-affil= affil-num=3 en-affil=Okayama University kn-affil= affil-num=4 en-affil=Okayama University kn-affil= en-keyword=system call kn-keyword=system call en-keyword=virtual machine monitor kn-keyword=virtual machine monitor en-keyword=operating system kn-keyword=operating system END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=107 end-page=119 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=Investigation Towards Detecting Landing Websites for?Fake Japanese Shopping Websites en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recently, the number of victims of fake shopping websites that imitate legitimate ones to defraud people has been increasing. It has been shown that fake shopping websites use legitimate defaced landing websites as their leading paths. Therefore, if the detection of landing websites for fake shopping websites can be achieved, it can assist in addressing these websites and reduce the opportunities for users to be redirected to fake shopping websites. In this study, we collect and investigate existing landing websites that redirect users to fake Japanese shopping websites and identify effective features for detecting them. We identified effective search terms for collecting landing websites for fake Japanese shopping websites and found that using Google searches with queries of top-level domain and product names was effective. We also investigated the conditions for activating analytical evasion functions in the collected landing websites for fake Japanese shopping websites and clarified the differences in search results between crawlers and users. en-copyright= kn-copyright= en-aut-name=MichishitaDaigo en-aut-sei=Michishita en-aut-mei=Daigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobayashiSatoru en-aut-sei=Kobayashi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= 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=12 cd-vols= no-issue=1 article-no= start-page=32 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Stability and water solubility of calcium ferrite-type aluminum-rich phase: implications for deep water cycle caused by subducting basaltic crusts en-subtitle= kn-subtitle= en-abstract= kn-abstract=The subducting crustal materials serve as a crucial channel for transporting water to the lower mantle. Recent experimental studies suggest that crustal materials such as basaltic crust can be a main water carrier and reservoir playing an important role on water cycling in the lower mantle. Despite being a primary mineral in crustal materials, the water solubility of calcium ferrite-type (CF) phase and its stability are unclear yet. A recent phase relation study of hydrous basalts showed Na-depletion in lower-mantle minerals, suggesting the presence of fluid possibly with high Na concentration and the absence of CF phase along the low-temperature slab geotherms, where Al-rich hydrous phase H and ferropericlase appear instead. These phases could consequently produce Na-depleted CF phase when reaching the dehydration temperature of Al-rich hydrous phase H. In this study, we investigated the stability and water solubility of CF-type MgAl2O4, which is a main CF component in a hydrous basalt, in water-bearing systems at 26?32 GPa and 1200?1900 ‹C using a Kawai-type multi-anvil press. Our results indicate that the stability of the CF phase is strongly influenced by water content in the system. Water contents of recovered CF phases estimated by Fourier-transform infrared spectroscopy show a limited variation between 73 and 87 ppm wt at a pressure of 26 GPa and temperatures of 1500?1900 ‹C. We suggest that CF phase could not be a primary water carrier at lower mantle depths. This emphasizes contributions of hydrous aluminous silica minerals to Earthfs deep water cycling and heterogeneous structures in the lower mantle due to the strong water partitioning to this phase compared with other constituent minerals. en-copyright= kn-copyright= en-aut-name=ZhangXinyue en-aut-sei=Zhang en-aut-mei=Xinyue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MashinoIzumi en-aut-sei=Mashino en-aut-mei=Izumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshiiTakayuki en-aut-sei=Ishii en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=Institute for Planetary Materials, Okayama University kn-affil= en-keyword=Water solubility kn-keyword=Water solubility en-keyword=CF phase kn-keyword=CF phase en-keyword=Single crystal kn-keyword=Single crystal en-keyword=FTIR kn-keyword=FTIR en-keyword=MORB kn-keyword=MORB END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=6 article-no= start-page=e70119 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250519 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Quantitative quality control of 3D water tank using image analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and objective: Accurate beam data acquisition using three-dimensional (3D) water tanks is essential for beam commissioning and quality control (QC) in clinical radiation therapy.

To assess deviations from the radiation isocenter, MV images were acquired and compared with digitally reconstructed radiographs (DRRs). These evaluations were performed at different speed settings (slow, medium, and fast) using ET CT Body Marker (BRAINLAB Inc., USA) mounted on the drive unit. A webcam was utilized to capture the images, and custom-developed tracking software was employed to analyze deviations in driving speed and positional errors.
Results: The mean error of the radiation isocenter was 0.37 } 0.09 mm. As the motor drive speed increased, the discrepancy between the set speed and the actual speed observed in the analysis also became larger. In gcontinuous mode,h the deviation from the displayed value was greater than that observed in gstep-by-step mode.h
Conclusion: It is demonstrated that the proposed analysis method can quantitatively evaluate radiation isocenter misalignment, tank setup position deviation, and both the indicated drive speed values and their stability. At higher drive speeds, the gstep-by-step modeh showed smaller deviations from the indicated values. en-copyright= kn-copyright= en-aut-name=TanimotoYuki en-aut-sei=Tanimoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugimotoKohei en-aut-sei=Sugimoto en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KoshiKazunobu en-aut-sei=Koshi en-aut-mei=Kazunobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiroshigeAkira en-aut-sei=Hiroshige en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshidaShohei en-aut-sei=Yoshida en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujitaYoshiki en-aut-sei=Fujita en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakahiraAtsuki en-aut-sei=Nakahira en-aut-mei=Atsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakanishiDaiki en-aut-sei=Nakanishi en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HondaHirofumi en-aut-sei=Honda en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OitaMasataka en-aut-sei=Oita en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Radiology, NHO Kure Medical Center and Chugoku Cancer Center kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Faculty of Health Science and Technology, Kawasaki University of Medical Welfare kn-affil= affil-num=3 en-affil=Department of Radiology, NHO Fukuyama Medical Center kn-affil= affil-num=4 en-affil=Department of Radiology, NHO Shikoku Cancer Center kn-affil= affil-num=5 en-affil=Department of Radiology, NHO Shikoku Cancer Center kn-affil= affil-num=6 en-affil=Department of Radiology, NHO Shikoku Cancer Center kn-affil= affil-num=7 en-affil=Department of Radiology, NHO Shikoku Cancer Center kn-affil= affil-num=8 en-affil=Division of Radiology, Department of Medical Technology, Kyushu University Hospital kn-affil= affil-num=9 en-affil=Department of Radiological Technology, Ehime University Hospital kn-affil= affil-num=10 en-affil=Department of Healthcare Science, Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=3D water tank kn-keyword=3D water tank en-keyword=drive speed stability kn-keyword=drive speed stability en-keyword=quality control kn-keyword=quality control en-keyword=radiation isocenter kn-keyword=radiation isocenter en-keyword=x-ray image analysis kn-keyword=x-ray image analysis END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=78 end-page=85 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Standardization of radiation therapy quality control system through mutual quality control based on failure mode and effects analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=The advancement of irradiation technology has increased the demand for quality control of radiation therapy equipment. Consequently, the number of quality control items and required personnel have also increased. However, differences in the proportion of qualified personnel to irradiation techniques have caused bias in quality control systems among institutions. To standardize the quality across institutions, researchers should conduct mutual quality control by analyzing the quality control data of one institution at another institution and comparing the results with those of their own institutions. This study uses failure mode and effects analysis (FMEA) to identify potential risks in 12 radiation therapy institutions, compares the results before and after implementation of mutual quality control, and examines the utility of mutual quality control in risk reduction. Furthermore, a cost-effectiveness factor is introduced into FMEA to evaluate the utility of mutual quality control. en-copyright= kn-copyright= en-aut-name=TanimotoYuki en-aut-sei=Tanimoto

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= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250616 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Leg-biting fights reduce the number of sperm transferred by the loser and in draws in Zophobas atratus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Intra-sexual selection has been observed across a wide range of species. Male-male combat can not only determine the winner and loser but also affect subsequent reproductive success. The effects of combat outcomes on reproduction are thought to depend on the reproductive ecology of the target species. However, to our knowledge, studies examining the impact of combat outcomes on sperm competition and fitness remain limited. In the giant mealworm (Zophobas atratus), malefs combat involves biting each other's hind legs. Females mated to the losers of leg-biting contests had significantly fewer eggs and fewer offspring than females mated to males that were not in a contest. Possible explanations for this fitness reduction include the inability of males to transfer sperm effectively due to the combat outcome or the inability of their sperm to fertilize eggs due to female cryptic sperm choice, and the mechanisms underlying this reduction remain unclear. Previous studies have observed distorted mating postures in losing males, leading us to hypothesize that leg-biting during combat might affect sperm transfer. To test this, we allowed uncontested males, winners, losers, and males with a draw outcome to mate with females and compared the number of sperm within the femalefs spermatheca. Additionally, we examined the correlation between combat duration and sperm count. Results showed that losers and males with draw transferred fewer sperm than non-combat males. Moreover, the longer the combat duration, the fewer sperm males were able to transfer. These findings suggest that the reduction in sperm transferred was affected by both losing in combat and prolonged combat duration in leg-biting encounters. en-copyright= kn-copyright= en-aut-name=MatsuuraTeruhisa en-aut-sei=Matsuura en-aut-mei=Teruhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Male combat kn-keyword=Male combat en-keyword=Male-male competition kn-keyword=Male-male competition en-keyword=Sperm transfer kn-keyword=Sperm transfer en-keyword=Sperm biology kn-keyword=Sperm biology END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=5 article-no= start-page=733 end-page=747 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=A PRA-Rab trafficking machinery modulates NLR immune receptor plasma membrane microdomain anchoring and blast resistance in rice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nucleotide-binding leucine-rich repeat (NLR) receptors mediate pathogen effector-triggered immunity (ETI) in plants, and a subclass of NLRs are hypothesized to function at the plasma membrane (PM). However, how NLR traffic and PM delivery are regulated during immune responses remains largely unknown. The rice NLR PigmR confers broad-spectrum resistance to the blast fungus Magnaporthe oryzae. Here, we report that a PRA (Prenylated Rab acceptor) protein, PIBP4 (PigmR-INTERACTING and BLAST RESISTANCE PROTEIN 4), interacts with both PigmR and the active form of the Rab GTPase, OsRab5a, thereby loads a portion of PigmR on trafficking vesicles that target to PM microdomains. Microdomain-localized PigmR interacts with and activates the small GTPase OsRac1, which triggers reactive oxygen species signaling and hypersensitive response, leading to immune responses against blast infection. Thus, our study discovers a previously unknown mechanism that deploys a PRA-Rab protein delivering hub to ensure ETI, linking the membrane trafficking machinery with NLR function and immune activation in plants. en-copyright= kn-copyright= en-aut-name=LiangDi en-aut-sei=Liang en-aut-mei=Di kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YangDongyong en-aut-sei=Yang

materials have unique structures that can be modified by adjusting the space between layers through pillaring or surface functionalization. Unlike typical crystalline layered materials, graphene oxide (GO) possesses reactive oxygenated functional groups, which lead to spontaneous reduction and stacking upon thermal treatment. Here, we investigated the functionalization of GO with different amounts of hexylamine to control the degree of surface coverage. Furthermore, octylamine and dodecylamine were employed to confirm the effect of the alkyl chain length on the interlayer distance of the resultant GO derivatives. Subsequent thermal treatment produced reduced GO (rGO) functionalized with alkylamines, demonstrating the retention of the interlayer distance. Additionally, amine-functionalized rGOs exhibited varying porous structures. en-copyright= kn-copyright= en-aut-name=Ortiz-AnayaIsrael en-aut-sei=Ortiz-Anaya en-aut-mei=Israel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ObataSeiji en-aut-sei=Obata en-aut-mei=Seiji 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=Graduate School of Natural Sciences and Technology, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=Graphene oxide kn-keyword=Graphene oxide en-keyword=Layered material kn-keyword=Layered material en-keyword=Interlayer distance kn-keyword=Interlayer distance en-keyword=Functionalization kn-keyword=Functionalization en-keyword=Alkylamines kn-keyword=Alkylamines en-keyword=Nitrogen physisorption kn-keyword=Nitrogen physisorption END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=RP99858 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241031 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structural basis for molecular assembly of fucoxanthin chlorophyll a/c-binding proteins in a diatom photosystem I supercomplex en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photosynthetic organisms exhibit remarkable diversity in their light-harvesting complexes (LHCs). LHCs are associated with photosystem I (PSI), forming a PSI-LHCI supercomplex. The number of LHCI subunits, along with their protein sequences and pigment compositions, has been found to differ greatly among the PSI-LHCI structures. However, the mechanisms by which LHCIs recognize their specific binding sites within the PSI core remain unclear. In this study, we determined the cryo-electron microscopy structure of a PSI supercomplex incorporating fucoxanthin chlorophyll a/c-binding proteins (FCPs), designated as PSI-FCPI, isolated from the diatom Thalassiosira pseudonana CCMP1335. Structural analysis of PSI-FCPI revealed five FCPI subunits associated with a PSI monomer; these subunits were identified as RedCAP, Lhcr3, Lhcq10, Lhcf10, and Lhcq8. Through structural and sequence analyses, we identified specific protein?protein interactions at the interfaces between FCPI and PSI subunits, as well as among FCPI subunits themselves. Comparative structural analyses of PSI-FCPI supercomplexes, combined with phylogenetic analysis of FCPs from T. pseudonana and the diatom Chaetoceros gracilis, underscore the evolutionary conservation of protein motifs crucial for the selective binding of individual FCPI subunits. These findings provide significant insights into the molecular mechanisms underlying the assembly and selective binding of FCPIs in diatoms. en-copyright= kn-copyright= en-aut-name=KatoKoji

en-abstract= kn-abstract=Phosphate is an essential nutrient, but in high concentrations it contributes to water pollution. Traditional methods for phosphate measurement, such as absorption spectrophotometry and ion chromatography, require expensive equipment and skilled operators. This study introduces a microfluidic paper-based analytical device (ƒÊPAD) that is designed to accomplish field-based, low-concentration phosphate measurements. This ƒÊPAD utilizes colorimetric detection based on the molybdenum blue method. Herein, we describe how the conditions were optimized in terms of design and sensitivity by adjusting reagent concentrations, paper thickness, and the time frames for sample introduction, and reaction. The operation consists of simply dipping the ƒÊPAD into a sample, capturing images in a home-made photo studio box, and processing the images with ImageJ software to measure RGB intensity. An additional preconcentration step involves solid-phase extraction with an anion exchange resin that achieves a 10-fold enrichment, which enables detection that ranges from 0.05 to 1 mg L?1 with a detection limit of 0.089 mg L?1 and a quantification limit of 0.269 mg L?1. The replicated measurements showed good reproducibility both intraday and interday (five different days) as 4.7 % and 3.0 % of relative standard deviations, respectively. After storage in a refrigerator for as long as 26 days, this ƒÊPAD delivered stable and accurate results for real-world samples of natural water, soil, and toothpaste. The results produced using this system correlate well with those produced via spectrophotometry. This ƒÊPAD-based method is a cost-effective, portable, rapid, and simple approach that allows relatively unskilled operators to monitor phosphate concentrations in field applications. en-copyright= kn-copyright= en-aut-name=DanchanaKaewta en-aut-sei=Danchana en-aut-mei=Kaewta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NambaHaruka en-aut-sei=Namba en-aut-mei=Haruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanetaTakashi en-aut-sei=Kaneta en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Chemistry, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Okayama University kn-affil= affil-num=3 en-affil=Department of Chemistry, Okayama University kn-affil= en-keyword=Phosphate kn-keyword=Phosphate en-keyword=Microfluidic paper-based analytical device kn-keyword=Microfluidic paper-based analytical device en-keyword=Solid-phase extraction kn-keyword=Solid-phase extraction en-keyword=Anion exchanger kn-keyword=Anion exchanger en-keyword=Molybdenum blue method kn-keyword=Molybdenum blue method END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=20 article-no= start-page=eadv7488 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250516 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structure of a photosystem I supercomplex from Galdieria sulphuraria close to an ancestral red alga en-subtitle= kn-subtitle= en-abstract= kn-abstract=Red algae exhibit unique photosynthetic adaptations, characterized by photosystem I (PSI) supercomplexes containing light-harvesting complexes (LHCs), forming PSI-LHCI supercomplexes. In this study, we solved the PSI-LHCI structure of Galdieria sulphuraria NIES-3638 at 2.19-angstrom resolution using cryo-electron microscopy, revealing a PSI monomer core associated with seven LHCI subunits. Structural analysis uncovered the absence of phylloquinones, the common secondary electron acceptor in PSI of photosynthetic organisms, suggesting adaptation to a benzoquinone-like molecule. Phylogenetic analysis suggests that G. sulphuraria retains traits characteristic of an ancestral red alga, including distinctive LHCI binding and interaction patterns. Variations in LHCI composition and interactions across red algae, particularly in red-lineage chlorophyll a/b-binding-like protein and red algal LHCs, highlight evolutionary divergence and specialization. These findings not only deepen our understanding of red algal PSI-LHCI diversification but also enable us to predict features of an ancestral red algal PSI-LHCI supercomplex, providing a framework to explore evolutionary adaptations from an ancestral red alga. en-copyright= kn-copyright= en-aut-name=KatoKoji en-aut-sei=Kato en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KumazawaMinoru en-aut-sei=Kumazawa en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakajimaYoshiki en-aut-sei=Nakajima en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuzukiTakehiro en-aut-sei=Suzuki en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DohmaeNaoshi en-aut-sei=Dohmae en-aut-mei=Naoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShenJian-Ren en-aut-sei=Shen en-aut-mei=Jian-Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IfukuKentaro en-aut-sei=Ifuku en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NagaoRyo en-aut-sei=Nagao en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Research institute for interdisciplinary Science and Graduate School of environ-mental, life, natural Science and technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=3 en-affil=Research institute for interdisciplinary Science and Graduate School of environ-mental, life, natural Science and technology, Okayama University kn-affil= affil-num=4 en-affil=Biomolecular characterization Unit, RiKen center for Sustainable Resource Science kn-affil= affil-num=5 en-affil=Biomolecular characterization Unit, RiKen center for Sustainable Resource Science kn-affil= affil-num=6 en-affil=Research institute for interdisciplinary Science and Graduate School of environ-mental, life, natural Science and technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=8 en-affil=Faculty of Agriculture, Shizuoka University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=5 article-no= start-page=e0320426 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250519 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=LeFood-set: Baseline performance of predicting level of leftovers food dataset in a hospital using MT learning en-subtitle= kn-subtitle= en-abstract= kn-abstract=Monitoring the remaining food in patients' trays is a routine activity in healthcare facilities as it provides valuable insights into the patients' dietary intake. However, estimating food leftovers through visual observation is time-consuming and biased. To tackle this issue, we have devised an efficient deep learning-based approach that promises to revolutionize how we estimate food leftovers. Our first step was creating the LeFoodSet dataset, a pioneering large-scale open dataset explicitly designed for estimating food leftovers. This dataset is unique in its ability to estimate leftover rates and types of food. To the best of our knowledge, this is the first comprehensive dataset for this type of analysis. The dataset comprises 524 image pairs representing 34 Indonesian food categories, each with images captured before and after consumption. Our prediction models employed a combined visual feature extraction and late fusion approach utilizing soft parameter sharing. Here, we used multi-task (MT) models that simultaneously predict leftovers and food types in training. In the experiments, we tested the single task (ST) model, the ST Model with Ground Truth (ST-GT), the MT model, and the MT model with Inter-task Connection (MT-IC). Our AI-based models, particularly the MT and MT-IC models, have shown promising results, outperforming human observation in predicting leftover food. These findings show the best with the ResNet101 model, where the Mean Average Error (MAE) of leftover task and food classification accuracy task is 0.0801 and 90.44% in the MT Model and 0.0817 and 92.56% in the MT-IC Model, respectively. It is proved that the proposed solution has a bright future for AI-based approaches in medical and nursing applications. en-copyright= kn-copyright= en-aut-name=SariYuita Arum en-aut-sei=Sari en-aut-mei=Yuita Arum kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakazawaAtsushi en-aut-sei=Nakazawa en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WaniYudi Arimba en-aut-sei=Wani en-aut-mei=Yudi Arimba kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=Nutrition Department, Faculty of Health Sciences, Brawijaya University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=4175 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structure of a photosystem II-FCPII supercomplex from a haptophyte reveals a distinct antenna organization en-subtitle= kn-subtitle= en-abstract= kn-abstract=Haptophytes are unicellular algae that produce 30 to 50% of biomass in oceans. Among haptophytes, a subset named coccolithophores is characterized by calcified scales. Despite the importance of coccolithophores in global carbon fixation and CaCO3 production, their energy conversion system is still poorly known. Here we report a cryo-electron microscopic structure of photosystem II (PSII)-fucoxanthin chlorophyll c-binding protein (FCPII) supercomplex from Chyrostila roscoffensis, a representative of coccolithophores. This complex has two sets of six dimeric and monomeric FCPIIs, with distinct orientations. Interfaces of both FCPII/FCPII and FCPII/core differ from previously reported. We also determine the sequence of Psb36, a subunit previously found in diatoms and red algae. The principal excitation energy transfer (EET) pathways involve mainly 5 FCPIIs, where one FCPII monomer mediates EET to CP47. Our findings provide a solid structural basis for EET and energy dissipation pathways occurring in coccolithophores. en-copyright= kn-copyright= en-aut-name=La RoccaRomain en-aut-sei=La Rocca en-aut-mei=Romain kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatoKoji en-aut-sei=Kato en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsaiPi-Cheng en-aut-sei=Tsai en-aut-mei=Pi-Cheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakajimaYoshiki en-aut-sei=Nakajima en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AkitaFusamichi en-aut-sei=Akita en-aut-mei=Fusamichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShenJian-Ren en-aut-sei=Shen en-aut-mei=Jian-Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, and Advanced Research Field, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, and Advanced Research Field, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, and Advanced Research Field, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, and Advanced Research Field, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, and Advanced Research Field, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, and Advanced Research Field, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=3 article-no= start-page=157 end-page=166 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=Continuous Stimulation with Glycolaldehyde-derived Advanced Glycation End Product Reduces Aggrecan and COL2A1 Production via RAGE in Human OUMS-27 Chondrosarcoma Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chondrocytes are responsible for the production of extracellular matrix (ECM) components such as collagen type II alpha-1 (COL2A1) and aggrecan, which are loosely distributed in articular cartilage. Chondrocyte dysfunction has been implicated in the pathogenesis of rheumatic diseases such as osteoarthritis (OA) and rheumatoid arthritis (RA). With age, advanced glycation end products (AGEs) accumulate in all tissues and body fluids, including cartilage and synovial fluid, causing and accelerating pathological changes associated with chronic diseases such as OA. Glycolaldehyde-derived AGE (AGE3), which is toxic to a variety of cell types, have a stronger effect on cartilage compared with other AGEs. To understand the long-term effects of AGE3 on cartilage, we stimulated a human chondrosarcoma cell line (OUMS-27), which exhibits a chondrocytic phenotype, with 10 ƒÊg/ml AGE3 for 4 weeks. As a result, the expressions of COL2A1 and aggrecan were significantly downregulated in the OUMS-27 cells without inducing cell death, but the expressions of proteases that play an important role in cartilage destruction were not affected. Inhibition of the receptor for advanced glycation end products (RAGE) suppressed the AGE3-induced reduction in cartilage component production, suggesting the involvement of RAGE in the action of AGE3. en-copyright= kn-copyright= en-aut-name=HatipogluOmer Faruk en-aut-sei=Hatipoglu en-aut-mei=Omer Faruk kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishinakaTakashi en-aut-sei=Nishinaka en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YaykasliKursat Oguz en-aut-sei=Yaykasli en-aut-mei=Kursat Oguz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriShuji en-aut-sei=Mori en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WatanabeMasahiro en-aut-sei=Watanabe en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ToyomuraTakao en-aut-sei=Toyomura en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishiboriMasahiro en-aut-sei=Nishibori en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HirohataSatoshi en-aut-sei=Hirohata en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakahashiHideo en-aut-sei=Takahashi en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=WakeHidenori en-aut-sei=Wake en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Pharmacology, Faculty of Medicine, Kindai University kn-affil= affil-num=2 en-affil=Department of Pharmacology, Faculty of Medicine, Kindai University kn-affil= affil-num=3 en-affil=Department of Internal Medicine 3-Rheumatology and Immunology, Friedrich-Alexander-University Erlangen-N?rnberg (FAU) and Universit?tsklinikum Erlangen kn-affil= affil-num=4 en-affil=Department of Pharmacology, School of Pharmacy, Shujitsu University kn-affil= affil-num=5 en-affil=Department of Pharmacology, School of Pharmacy, Shujitsu University kn-affil= affil-num=6 en-affil=Department of Pharmacology, School of Pharmacy, Shujitsu University kn-affil= affil-num=7 en-affil=Department of Translational Research & Dug Development, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Pharmacology, Faculty of Medicine, Kindai University kn-affil= affil-num=10 en-affil=Department of Pharmacology, Faculty of Medicine, Kindai University kn-affil= en-keyword=advanced glycation end product kn-keyword=advanced glycation end product en-keyword=aging kn-keyword=aging en-keyword=cartilage kn-keyword=cartilage en-keyword=collagen kn-keyword=collagen en-keyword=aggrecan kn-keyword=aggrecan 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 ƒ¿ in different dimensions.

The synthetic utility of our transformation was demonstrated by follow-up transformations, including the first total synthesis of quinoline-2,4-dione alkaloid. en-copyright= kn-copyright= en-aut-name=TokushigeKeisuke en-aut-sei=Tokushige en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AbeTakumi en-aut-sei=Abe en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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= en-keyword=Deaminokynurenines kn-keyword=Deaminokynurenines en-keyword=Enolates kn-keyword=Enolates en-keyword=Indoline hemiaminals kn-keyword=Indoline hemiaminals en-keyword=Potassium tertbutoxide kn-keyword=Potassium tertbutoxide en-keyword=Tautomerism kn-keyword=Tautomerism 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.

Density functional theory calculations, cyclic voltammetry measurements, and constant potential electrolysis studies supported the proposed HAT mechanism. Moreover, the obtained carbonyl compounds could be functionalized in an electrochemical one-pot manner, further highlighting their synthetic utility. en-copyright= kn-copyright= en-aut-name=KawajiriTakahiro en-aut-sei=Kawajiri en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HosoyaMasahiro en-aut-sei=Hosoya en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GodaSatoshi en-aut-sei=Goda en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatoEisuke en-aut-sei=Sato en-aut-mei=Eisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= affil-num=1 en-affil=API R&D Laboratory, Research Division, Shionogi & Co., Ltd. kn-affil= affil-num=2 en-affil=API R&D Laboratory, Research Division, Shionogi & Co., Ltd. kn-affil= affil-num=3 en-affil=API R&D Laboratory, Research Division, Shionogi & Co., Ltd. kn-affil= affil-num=4 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=120 cd-vols= no-issue=1 article-no= start-page=241001 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=Metamorphic pressure-temperature conditions of garnet granulite from the Eastern Iratsu body in the Sambagawa belt, SW Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Several coarse-grained mafic bodies with evidence for eclogite-facies metamorphism are present in the Besshi area of the Sambagawa subduction-type metamorphic belt, SW Japan. Among them the granulite-bearing Eastern Iratsu metagabbro body involves an unresolved problem of whether it originated in the hanging-wall or footwall side of the subduction zone. The key to settle this problem is its relationship with the adjacent Western Iratsu metabasaltic body, which includes thick marble layer and certainly has the footwall ocean-floor origin. Several previous studies consider that the Western and Eastern Iratsu bodies were originally coherent in the footwall side and formed the shallower and deeper parts of a thick oceanic crust, respectively. The validity of this hypothesis may be assessed by deriving pressure-temperature history of the Eastern Iratsu body, or especially the pressure (depth) condition of the granulite-facies metamorphism before the eclogite-facies overprinting because, if the pressure was relatively high, the oceanic crust assumed in the above hypothesis might be too thick to tectonically achieve the present-day adjacence of the two bodies on the geological map. This study petrologically analyzes a garnet-bearing granulite from the Eastern Iratsu body and newly reports stable coexistence of garnet and orthopyroxene in the sample. By utilizing a garnet-orthopyroxene geothermobarometer, the minimum P-T conditions of the granulite-facies stage was estimated to be 0.8 GPa (? 27 km in depth) and 780 ‹C. If the Western and Eastern Iratsu bodies were assumed to have formed a coherent oceanic crust before their subduction, the original thickness of it was >27 km and this demands unusually strong ductile shortening (<1/9) or unrealistically large vertical displacement on intraplate faulting, suggesting invalidity of the assumption. The Western and Eastern Iratsu bodies, therefore, are originally bounded by subduction-boundary fault and the obtained pressure of 0.8 GPa can be interpreted to represent that of the hanging-wall lower continental crust in the subduction zone, where the Eastern Iratsu body originated. After the granulite-facies metamorphism, the Western Iratsu body, which was located near the footwall surface, initiated subduction and was subsequently juxtaposed with the above-located Eastern Iratsu body at the corresponding depth (? 27 km or greater) along the subduction boundary. en-copyright= kn-copyright= en-aut-name=NAKAMURADaisuke en-aut-sei=NAKAMURA en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AOYAMutsuki en-aut-sei=AOYA en-aut-mei=Mutsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OKAMURATomoki en-aut-sei=OKAMURA en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Technology, Industrial and Social Sciences, Tokushima University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Sambagawa belt kn-keyword=Sambagawa belt en-keyword=Iratsu body kn-keyword=Iratsu body en-keyword=Metagabbro kn-keyword=Metagabbro en-keyword=Granulite kn-keyword=Granulite en-keyword=Hanging wall kn-keyword=Hanging wall END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=5 article-no= start-page=e70087 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genomic Islands of Pseudomonas syringae pv. tabaci 6605: Identification of PtaGI-1 as a Pathogenicity Island With Effector Genes and a Tabtoxin Cluster en-subtitle= kn-subtitle= en-abstract= kn-abstract=Genomic islands (GIs) are 20-500 kb DNA regions that are thought to be acquired by horizontal gene transfer. 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=18 cd-vols= no-issue=9 article-no= start-page=1983 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250427 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Initial Bonding Performance to CAD/CAM Restorative Materials: The Impact of Stepwise Concentration Variation in 8-Methacryloxyoctyl Trimethoxy Silane and 3-Methacryloxypropyl Trimethoxy Silane on Feldspathic Ceramic, Lithium Disilicate Glass-Ceramic, and Polymer-Infiltrated Ceramic en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study investigated the effects of varying concentrations of two distinct silane agents, 8-methacryloxyoctyl trimethoxy silane (8-MOTS) and 3-methacryloxypropyl trimethoxy silane (ƒÁ-MPTS), on their initial bonding efficacy to feldspathic ceramic (FC), lithium disilicate glass-ceramic (LD) and polymer-infiltrated ceramic (PIC) specimens, in 10% increments for concentrations ranging from 10% to 40%. Shear bond strengths between the ceramic substrates and the luting material were assessed following 24 h incubation in distilled water. For FC, the median value of shear bond strength peaked at 20% of ƒÁ-MPTS (7.4 MPa), while 8-MOTS exhibited a concentration-dependent increase, reaching its highest value at 40% (13.1 MPa). For LD, ƒÁ-MPTS above 10% yielded similar strength median values (10.2 MPa), whereas 8-MOTS at 30% (15.8 MPa) and 40% (13.4 MPa) yielded higher strength values than at 10% (2.9 MPa) and 20% (4.1 MPa), with the highest median value exhibited at 30%. For PIC, both ƒÁ-MPTS and 8-MOTS demonstrated similarly low bond strength values which were not significantly different from the non-silane-treated specimens. When applied on silica-based FC and LD, silane revealed a concentration-dependent bonding effect, with 8-MOTS exhibiting superior bond strength to ƒÁ-MPTS. However, PIC, characterized by a high inorganic filler content, demonstrated limited bondability with both silanes. en-copyright= kn-copyright= en-aut-name=MaruoYukinori en-aut-sei=Maruo en-aut-mei=Yukinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuwaharaMiho en-aut-sei=Kuwahara en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshiharaKumiko en-aut-sei=Yoshihara en-aut-mei=Kumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IrieMasao en-aut-sei=Irie en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NagaokaNoriyuki en-aut-sei=Nagaoka en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshizaneMai en-aut-sei=Yoshizane en-aut-mei=Mai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoTakuya en-aut-sei=Matsumoto en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AkiyamaKentaro en-aut-sei=Akiyama en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Prosthodontics, Okayama University kn-affil= affil-num=2 en-affil=Department of Occlusal and Oral Functional Rehabilitation, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Health Research Institute, National Institute of Advanced Industrial Science and Technology kn-affil= affil-num=4 en-affil=Department of Biomaterials, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Advanced Research Center for Oral and Craniofacial Sciences, Okayama University Dental School kn-affil= affil-num=6 en-affil=Department of Occlusal and Oral Functional Rehabilitation, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Biomaterials, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Occlusal and Oral Functional Rehabilitation, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=silane coupling kn-keyword=silane coupling en-keyword=bond strength kn-keyword=bond strength en-keyword=ceramic kn-keyword=ceramic en-keyword=feldspathic kn-keyword=feldspathic en-keyword=lithium kn-keyword=lithium en-keyword=polymer-infiltrated ceramic kn-keyword=polymer-infiltrated ceramic en-keyword=CAD/CAM kn-keyword=CAD/CAM 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. The results indicate that 229Th displays a 4+ oxidation state at the substitutional site of a Ca2+ ion, with charge compensated provided by two F? ions positioned at interstitial sites adjacent to 229Th. en-copyright= kn-copyright= en-aut-name=TakatoriS. en-aut-sei=Takatori en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PimonM. en-aut-sei=Pimon en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=PollittS. en-aut-sei=Pollitt en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BartokosM. en-aut-sei=Bartokos en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BeeksK. en-aut-sei=Beeks en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GrueneisA. en-aut-sei=Grueneis en-aut-mei=A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HirakiT. en-aut-sei=Hiraki en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HonmaT. en-aut-sei=Honma en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HosseiniN. en-aut-sei=Hosseini en-aut-mei=N. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=LeitnerA. en-aut-sei=Leitner en-aut-mei=A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MasudaT. en-aut-sei=Masuda en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MorawetzI en-aut-sei=Morawetz en-aut-mei=I kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=NittaK. en-aut-sei=Nitta en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=OkaiK. en-aut-sei=Okai en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=RiebnerT. en-aut-sei=Riebner en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=SchadenF. en-aut-sei=Schaden en-aut-mei=F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=SchummT. en-aut-sei=Schumm en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=SekizawaO. en-aut-sei=Sekizawa en-aut-mei=O. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= en-aut-name=SikorskyT. en-aut-sei=Sikorsky en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=19 ORCID= en-aut-name=TakahashiY. en-aut-sei=Takahashi en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=20 ORCID= en-aut-name=De ColCol, L.

However, the effects of antigenicity on PD-1 expression in Treg cells and the resistance to PD-1 blockade therapy remain unclear. Here, we show that Treg cells gain high PD-1 expression through an antigen with high antigenicity. Additionally, tumors with high antigenicity for Treg cells were resistant to PD-1 blockade in vivo due to PD-1+ Treg-cell infiltration. Because such PD-1+ Treg cells have high cytotoxic T lymphocyte antigen (CTLA)-4 expression, resistance could be overcome by combination with an anti-CTLA-4 monoclonal antibody (mAb). Patients who responded to combination therapy with anti-PD-1 and anti-CTLA-4 mAbs sequentially after primary resistance to PD-1 blockade monotherapy showed high Treg cell infiltration. We propose that the high antigenicity of Treg cells confers resistance to PD-1 blockade therapy via high PD-1 expression in Treg cells, which can be overcome by combination therapy with an anti-CTLA-4 mAb. en-copyright= kn-copyright= en-aut-name=MatsuuraHiroaki en-aut-sei=Matsuura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshinoTakamasa en-aut-sei=Ishino en-aut-mei=Takamasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NinomiyaToshifumi en-aut-sei=Ninomiya en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NinomiyaKiichiro en-aut-sei=Ninomiya en-aut-mei=Kiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TachibanaKota en-aut-sei=Tachibana en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Honobe-TabuchiAkiko en-aut-sei=Honobe-Tabuchi en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MutoYoshinori en-aut-sei=Muto en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=InozumeTakashi en-aut-sei=Inozume en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UedaYouki en-aut-sei=Ueda en-aut-mei=Youki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OhashiKadoaki en-aut-sei=Ohashi en-aut-mei=Kadoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NagasakiJoji en-aut-sei=Nagasaki en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TogashiYosuke en-aut-sei=Togashi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Tumor Microenvironment, Okayama University kn-affil= affil-num=2 en-affil=Department of Tumor Microenvironment, Okayama University kn-affil= affil-num=3 en-affil=Department of Tumor Microenvironment, Okayama University kn-affil= affil-num=4 en-affil=Department of Hematology, Oncology and Respiratory Medicine,Okayama University kn-affil= affil-num=5 en-affil=Department of Dermatology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Dermatology, University of Yamanashi kn-affil= affil-num=7 en-affil=Department of Dermatology, University of Yamanashi kn-affil= affil-num=8 en-affil=Department of Dermatology, University of Yamanashi kn-affil= affil-num=9 en-affil=Department of Tumor Microenvironment, Okayama University kn-affil= affil-num=10 en-affil=Department of Hematology, Oncology and Respiratory Medicine,Okayama University kn-affil= affil-num=11 en-affil=Department of Hematology, Oncology and Respiratory Medicine,Okayama University kn-affil= affil-num=12 en-affil=Department of Tumor Microenvironment, Okayama University kn-affil= affil-num=13 en-affil=Department of Tumor Microenvironment, Okayama University kn-affil= en-keyword=antigenicity kn-keyword=antigenicity en-keyword=cancer immunotherapy kn-keyword=cancer immunotherapy en-keyword=CTLA-4 kn-keyword=CTLA-4 en-keyword=PD-1 kn-keyword=PD-1 en-keyword=regulatory T cell kn-keyword=regulatory T cell END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=8 article-no= start-page=18515 end-page=18529 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=Demonstration of enhanced Raman scattering in high-Q silicon nanocavities operating below the silicon band-gap wavelength en-subtitle= kn-subtitle= en-abstract= kn-abstract=We experimentally determined the quality factor (Q) and the intensity of the Raman scattered light for different silicon photonic-crystal nanocavities operating at wavelengths shorter than the silicon band-gap wavelength. Despite the relatively large absorption of silicon in this wavelength region, we observed Q values greater than 10,000 for cavities with a resonance wavelength of 1.05 mu m, and Q values greater than 30,000 for cavities with a resonance wavelength of 1.10 mu m. Additionally, we measured the Raman scattering spectra of cavities with resonance wavelengths of 1.10 mu m and 1.21 mu m. On average, the generation efficiency of the Raman scattered light in a 1.10-mu m nanocavity is 6.5 times higher than that in a 1.21-mu m nanocavity. These findings suggest that silicon nanocavities operating below the silicon band-gap wavelength could be useful in the development of silicon-based light sources. en-copyright= kn-copyright= en-aut-name=ShimomuraYu en-aut-sei=Shimomura en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AsanoTakashi en-aut-sei=Asano en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshiharaAyumi en-aut-sei=Ishihara en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NodaSusumu en-aut-sei=Noda en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahashiYasushi en-aut-sei=Takahashi en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Physics and Electronics, Osaka Metropolitan University kn-affil= affil-num=2 en-affil=Department of Electronic Science and Engineering, Kyoto University kn-affil= affil-num=3 en-affil=Department of Physics and Electronics, Osaka Metropolitan University kn-affil= affil-num=4 en-affil=Department of Electronic Science and Engineering, Kyoto University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=214 cd-vols= no-issue= article-no= start-page=32 end-page=41 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Medaka approach to evolutionary social neuroscience en-subtitle= kn-subtitle= en-abstract= kn-abstract=Previously, the integration of comparative biological and neuroscientific approaches has led to significant advancements in social neuroscience. This review highlights the potential and future directions of evolutionary social neuroscience research utilizing medaka fishes (the family Adrianichthyidae) including Japanese medaka (Oryzias latipes). We focus on medaka social cognitive capabilities and mate choice behavior, particularly emphasizing mate preference using visual cues. Medaka fishes are also advantageous due to their abundant genetic resources, extensive genomic information, and the relative ease of laboratory breeding and genetic manipulation. Here we present some research examples of both the conventional neuroscience approach and evolutionary approach involving medaka fishes and other species. We also discuss the prospects of uncovering the molecular and cellular mechanisms underlying the diversity of visual mate preference among species. Especially, we introduce that the single-cell transcriptome technology, particularly in conjunction with 'Adaptive Circuitry Census', is an innovative tool that bridges comparative biological methods and neuroscientific approaches. Evolutionary social neuroscience research using medaka has the potential to unveil fundamental principles in neuroscience and elucidate the mechanisms responsible for generating diversity in mating strategies. en-copyright= kn-copyright= en-aut-name=AnsaiSatoshi en-aut-sei=Ansai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Hiraki-KajiyamaTowako en-aut-sei=Hiraki-Kajiyama en-aut-mei=Towako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UedaRyutaro en-aut-sei=Ueda en-aut-mei=Ryutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SekiTakahide en-aut-sei=Seki en-aut-mei=Takahide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YokoiSaori en-aut-sei=Yokoi en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatsumuraTakafumi en-aut-sei=Katsumura en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakeuchiHideaki en-aut-sei=Takeuchi en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Ushimado Marine Institute, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Life Sciences, Tohoku University kn-affil= affil-num=3 en-affil=Graduate School of Life Sciences, Tohoku University kn-affil= affil-num=4 en-affil=Graduate School of Life Sciences, Tohoku University kn-affil= affil-num=5 en-affil=School of Pharmaceutical Sciences, Hokkaido University kn-affil= affil-num=6 en-affil=School of Medicine, Kitasato University kn-affil= affil-num=7 en-affil=Graduate School of Life Sciences, Tohoku University kn-affil= en-keyword=Evolutionary neuroscience kn-keyword=Evolutionary neuroscience en-keyword=Comparative neuroscience kn-keyword=Comparative neuroscience en-keyword=Medaka bioresource kn-keyword=Medaka bioresource en-keyword=Visual mate preference kn-keyword=Visual mate preference en-keyword=Sexual selection kn-keyword=Sexual selection en-keyword=Genetic manipulation kn-keyword=Genetic manipulation END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=1 article-no= start-page=1 end-page=15 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Improved sedimentary layer model including the accretionary prism in the fore-arc region of the Ryukyu arc, Japan kn-title=“ì¼”“‡‚Ì‘OŒÊˆæ‚É‚¨‚¯‚é•t‰Á‘Ì‚ðŠÜ‚Þ‘ÍÏ‘w‚̃‚ƒfƒ‹‰» en-subtitle= kn-subtitle= en-abstract= kn-abstract=@We combine the recent seismic reflection profiles to construct a new seismic velocity model of the sedimentary layer incorporating the accretionary prism along the Ryukyu trench. In constructing the new model, we refer to the zoning (ZONE1 to ZONE4) identified by Okamura et al. (2017, Tectonophys.). The construction process consists of the following steps: First, we digitize either unconformities or VP=4 to 5 km/s lines as the seismic basement, whichever is more clearly identifiable. Second, the digitized thickness data of the sedimentary layer from the reflection profiles are geometrically modeled and interpolated to make the three-dimensional structure model. Finally, we supplement the external region of the constructed 3-D sedimentary model using the J-SHIS model provided by the NIED to complete the velocity structure model in the entire Ryukyu arc. The main features of our model are as follows: In ZONE1, off Ishigaki-jima island, the thick sedimentary layer extends about 50 km wide from the Ryukyu trench. In ZONE2, off Miyako-jima island, the thinner layer compared to the other zones is found near the trench, with a thin sedimentary terrace covering the area behind it. In ZONE3, off Okinawa-jima island, the sedimentary layer deepens as it approaches the trench. In ZONE4, off Tokara islands, the deepest layer among all zones is identified. We then conduct 3-D finite-difference simulations of seismic wave propagation using the new and the previous models to confirm the improvement of the new model. In the simulations, the effects of the accretionary prism along the Ryukyu trench on the seismic wave propagation are clearly identified. en-copyright= kn-copyright= en-aut-name=KOMATSUMasanao en-aut-sei=KOMATSU en-aut-mei=Masanao kn-aut-name=¬¼³’¼ kn-aut-sei=¬¼ kn-aut-mei=³’¼ aut-affil-num=1 ORCID= en-aut-name=URAKAMISohei en-aut-sei=URAKAMI en-aut-mei=Sohei kn-aut-name=‰Yã‘z•½ kn-aut-sei=‰Yã kn-aut-mei=‘z•½ aut-affil-num=2 ORCID= en-aut-name=OKAMOTOTaro en-aut-sei=OKAMOTO en-aut-mei=Taro kn-aut-name=‰ªŒ³‘¾˜Y kn-aut-sei=‰ªŒ³ kn-aut-mei=‘¾˜Y aut-affil-num=3 ORCID= en-aut-name=TAKENAKAHiroshi en-aut-sei=TAKENAKA en-aut-mei=Hiroshi kn-aut-name=’|’†”ŽŽm kn-aut-sei=’|’† kn-aut-mei=”ŽŽm aut-affil-num=4 ORCID= affil-num=1 en-affil=Okayama Gakuin University kn-affil=‰ªŽRŠw‰@‘åŠw affil-num=2 en-affil=Formerly Department of Earth Sciences, Okayama University kn-affil=Œ³E‰ªŽR‘åŠw‘åŠw‰@Ž©‘R‰ÈŠwŒ¤‹†‰È affil-num=3 en-affil=Department of Earth and Planetary Sciences, School of Science, Institute of Science Tokyo kn-affil=“Œ‹ž‰ÈŠw‘åŠw—Šw‰@’n‹…˜f¯‰ÈŠwŒn affil-num=4 en-affil=Department of Earth Sciences, Okayama University kn-affil=‰ªŽR‘åŠwŠwpŒ¤‹†‰@ŠÂ‹«¶–½Ž©‘R‰ÈŠwŠwˆæ en-keyword=Sedimentary layer model kn-keyword=Sedimentary layer model en-keyword=Accretionary prism kn-keyword=Accretionary prism en-keyword=Ryukyu arc kn-keyword=Ryukyu arc END start-ver=1.4 cd-journal=joma no-vol=220 cd-vols= no-issue= article-no= start-page=115401 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250502 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genomic landscape and clinical impact of homologous recombination repair gene mutation in small bowel adenocarcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Small bowel adenocarcinoma (SBA) is a rare malignancy with a poor prognosis and limited treatment options. 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=13 cd-vols= no-issue=4 article-no= start-page=139 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Implementation of Creep Test Assisting System with Dial Gauge Needle Reading and Smart Lighting Function for Laboratory Automation en-subtitle= kn-subtitle= en-abstract= kn-abstract=For decades, analog dial gauges have been essential for measuring and monitoring data at various industrial instruments including production machines and laboratory equipment. Among them, we focus on the instrument for creep test in a mechanical engineering laboratory, which evaluates material strength under sustained stress. Manual reading of gauges imposes significant labor demands, especially in long-duration tests. This burden further increases under low-lighting environments, where poor visibility can lead to misreading data points, potentially compromising the accuracy of test results. In this paper, to address the challenges, we implement a creep test assisting system that possesses the following features: (1) to save the installation cost, a web camera and Raspberry Pi are employed to capture images of the dial gauge and automate the needle reading by image processing in real time, (2) to ensure reliability under low-lighting environments, a smart lighting mechanism is integrated to turn on a supplementary light when the dial gauge is not clearly visible, and (3) to allow a user to stay in a distant place from the instrument during a creep test, material break is detected and the corresponding message is notified to a laboratory staff using LINE automatically. For evaluations, we install the implemented system into a material strength measuring instrument at Okayama University, Japan, and confirm the effectiveness and accuracy through conducting experiments under various lighting conditions. en-copyright= kn-copyright= en-aut-name=KongDezheng en-aut-sei=Kong en-aut-mei=Dezheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FangShihao en-aut-sei=Fang en-aut-mei=Shihao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NopriantoMitsuhiro en-aut-sei=Noprianto en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkayasuMitsuhiro en-aut-sei=Okayasu en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=PuspitaningayuPradini en-aut-sei=Puspitaningayu en-aut-mei=Pradini 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=Department of Electrical Engineering, Universitas Negeri Surabaya kn-affil= en-keyword=creep test kn-keyword=creep test en-keyword=Raspberry Pi kn-keyword=Raspberry Pi en-keyword=dial gauge kn-keyword=dial gauge en-keyword=needle reading kn-keyword=needle reading en-keyword=smart lighting kn-keyword=smart lighting END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=2 article-no= start-page=43 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250317 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Molecular Iodine-Catalyzed Synthesis of 3,3-Disubstituted Isatins: Total Synthesis of Indole Alkaloid, 3,3-Dimethoxy-2-oxindole en-subtitle= kn-subtitle= en-abstract= kn-abstract=3,3-Dialkoxy-2-oxindoles are prevalent in natural products and exhibit unique biological activities. Among them, acyclic alkoxy analogues show instability in acidic conditions, making access to acyclic isatin ketals highly challenging. Conventional methods for the synthesis of 3,3-dialkoxy-2-oxindoles usually require strongly acidic and harsh reaction conditions, resulting in a low overall efficiency. Herein, we report on an acid- and metal-free protocol for the synthesis of 3,3-dialkoxy-2-oxindoles from isatins through an iodine-catalyzed ketalization. This photochemical protocol does not require the use of any specific reagents such as metal catalysts. Furthermore, the total synthesis of an unprecedented 2-oxindole alkaloid bearing 3,3-dimethoxy moiety is achieved. en-copyright= kn-copyright= en-aut-name=TokushigeKeisuke en-aut-sei=Tokushige en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AsaiShota en-aut-sei=Asai en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AbeTakumi en-aut-sei=Abe en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=School of Pharmacy, Shujitsu University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=3,3-dialkoxyisatins kn-keyword=3,3-dialkoxyisatins en-keyword=isatins kn-keyword=isatins en-keyword=ketalization kn-keyword=ketalization en-keyword=iodine kn-keyword=iodine en-keyword=indole alkaloid kn-keyword=indole alkaloid END start-ver=1.4 cd-journal=joma no-vol=36 cd-vols= no-issue=3 article-no= start-page=374 end-page=380 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=Effect Modification in Settings with gTruncation by Deathh en-subtitle= kn-subtitle= en-abstract= kn-abstract=Epidemiologic studies recruiting individuals with higher-than-population-average mortality can be affected by gtruncation by death,h whereby the outcome of interest (e.g., quality of life) is considered not to be defined for individuals who die before the end of follow-up.

Further, we show that this principal effect can be expressed as a weighted average of this treatment effect for individuals with each level of these variables, and that these weights depend not only on the relative frequencies of the levels in the total population but also on the galways-survivorsh principal stratum. We also discuss the implications of this work for the transportability of the survivor average causal effect. en-copyright= kn-copyright= en-aut-name=Gon?alvesBronner P. en-aut-sei=Gon?alves en-aut-mei=Bronner P. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiEtsuji en-aut-sei=Suzuki en-aut-mei=Etsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Comparative Biomedical Sciences, Faculty of Health and Medical Sciences, University of Surrey kn-affil= affil-num=2 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Causal inference kn-keyword=Causal inference en-keyword=Effect modification kn-keyword=Effect modification en-keyword=Principal stratification kn-keyword=Principal stratification en-keyword=Transportability kn-keyword=Transportability 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=71 cd-vols= no-issue=1 article-no= start-page=19 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250419 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Quantitative assessment of adhesive effects on partial and full compressive strength of LVL in the edge-wise direction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Laminated wood-based materials have been widely developed, and the laminating process and adhesive itself have been reported to enhance performance beyond the sum of the individual layers' performance. This phenomenon is particularly notable under loads applied in the "edge-wise direction", where each layer bears stress collectively. These combined effects are referred to as the "adhesive effect". Strength under partial compressive loads is critical in timber engineering, as partial compressive stress generates complex stress distributions influenced by boundary conditions. The adhesive effect may also be impacted by these conditions. The aim of this study was to quantitatively and directly evaluate the adhesive effect under partial and full compressive loads using various parameters. The strength of laminated veneer lumber (LVL) with adhesive was compared to that of simply layered veneers without adhesive to assess the adhesive effect. Three mechanisms contributing to the adhesive effect were proposed: Mechanism I, caused by the deformation of the adhesive layer independently from the veneers; Mechanism II, resulting from the adhesive impregnating the veneers; and Mechanism III, arising from the reinforcement provided by adjacent veneers. The results suggested the following: (i) Mechanism I had minimal impact, as the fiber direction and the presence of additional length showed strong and slight effects on the adhesive effect, respectively; (ii) Mechanism II contributed to preventing crack propagation and altering the relationships among mechanical properties, with its effectiveness increasing as the adhesive weight increased; and (iii) Mechanism III functioned as a crossband effect, reinforcing weaknesses caused by the slope of the grain and the angle of the annual rings. en-copyright= kn-copyright= en-aut-name=SudoRyutaro en-aut-sei=Sudo en-aut-mei=Ryutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyamotoKohta en-aut-sei=Miyamoto en-aut-mei=Kohta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IdoHirofumi en-aut-sei=Ido en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= affil-num=2 en-affil=Forestry and Forest Products Research Institute kn-affil= affil-num=3 en-affil=Forestry and Forest Products Research Institute kn-affil= en-keyword=Laminated veneer lumber (LVL) kn-keyword=Laminated veneer lumber (LVL) en-keyword=Partial compressive load kn-keyword=Partial compressive load en-keyword=Bearing strength kn-keyword=Bearing strength en-keyword=Embedment strength kn-keyword=Embedment strength en-keyword=Partial compression perpendicular to grain (PCPG) kn-keyword=Partial compression perpendicular to grain (PCPG) en-keyword=Adhesive layer kn-keyword=Adhesive layer END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=109 end-page=116 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=Relationship between Personality Traits and Postpartum Depressive Symptoms in Women who Became Pregnant via Infertility Treatment en-subtitle= kn-subtitle= en-abstract= kn-abstract=The status of postpartum depression was elucidated herein with the use of the Edinburgh Postnatal Depression Scale (EPDS) in women in Shikoku, Japan who became pregnant and gave birth after undergoing infertility treatment, including assisted reproductive technology (ART). The assessment was performed during their childrenfs 4-month health examination. The relationships between postpartum depression and the mothersf background factors and scores on the Big Five personality traits scale were also examined. Of the Big Five personality traits, the scores for neuroticism were significantly higher in the ART group (n=71) than in the general infertility treatment (n=118) and natural pregnancy (n=872) groups. No significant differences in EPDS scores were seen among these three groups. A logistic regression analysis showed that neuroticism was associated with an EPDS score †9 points, (which is suggestive of postpartum depression, ) in all groups. Moreover, although a long-standing marriage had an inhibitory effect on postpartum depression in the natural pregnancy group, no such trend was seen in the ART group, which included many women with long-standing marriages. Particularly for women who become pregnant by ART, an individualized response that pays close attention to the womanfs personality traits is needed. en-copyright= kn-copyright= en-aut-name=AwaiKyoko en-aut-sei=Awai en-aut-mei=Kyoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakatsukaMikiya en-aut-sei=Nakatsuka en-aut-mei=Mikiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=infertility treatment kn-keyword=infertility treatment en-keyword=assisted reproductive technology kn-keyword=assisted reproductive technology en-keyword=postpartum kn-keyword=postpartum en-keyword=postpartum depression kn-keyword=postpartum depression en-keyword=personality trait kn-keyword=personality trait 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, teacherfs 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=79 cd-vols= no-issue=2 article-no= start-page=75 end-page=80 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=Potential for Radiation Dose Reduction in Temporal Bone CT Imaging Using Photon-Counting Detector CT en-subtitle= kn-subtitle= en-abstract= kn-abstract=Temporal bone computed tomography (CT) is frequently performed for pediatric patients with ear diseases. Advances in CT technology have improved diagnostic imaging quality, but reduction of radiation exposure remains a goal. We evaluated the potential for radiation dose reduction in temporal bone CT examinations using porcine ear ossicles and a photon-counting detector CT system. Three scans of the bilateral temporal bone were performed on each of three pig cadaver heads. In each of seven successive imaging sessions, the radiation dose was reduced by an additional one-seventh of the recommended dose (RD). Two board-certified radiologists independently scored the resulting images on a scale of 1 to 5 points, where 5 represented the image quality at the RD. Images scoring ?4.5 points were considered acceptable. Noise was assessed in a 2-cm-diameter region near the ear ossicles, and standard deviation was measured for each of the seven decrements from the RD. As the radiation dose decreased, the noise progressively increased, and visual assessment scores progressively decreased. Acceptable image scores were obtained at six-sevenths (4.9), five-sevenths (4.8), four-sevenths (4.7), and three-sevenths (4.6) of the RD. Thus, acceptable porcine temporal bone CT images were obtained with a radiation dose reduction of approximately 50%. en-copyright= kn-copyright= en-aut-name=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorimitsuYusuke en-aut-sei=Morimitsu en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HwangSung Il en-aut-sei=Hwang en-aut-mei=Sung Il kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KitayamaTakahiro en-aut-sei=Kitayama en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakahashiYuka en-aut-sei=Takahashi en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UkaMayu en-aut-sei=Uka en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AkagiNoriaki en-aut-sei=Akagi en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SugayaAkiko en-aut-sei=Sugaya en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Radiology, Seoul National University Bundang Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Otolaryngology-Head and Neck Surgery, Okayama University Hospital kn-affil= affil-num=10 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=computed tomography kn-keyword=computed tomography en-keyword=photon-counting detector computed tomography kn-keyword=photon-counting detector computed tomography en-keyword=ear ossicle kn-keyword=ear ossicle en-keyword=energy-integrating detector computed tomography kn-keyword=energy-integrating detector computed tomography 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.

Under these circumstances, companies must take into account constraints such as the amount of management resources that can be invested, and make decisions about the time to spend for exploration. The purpose of this paper is to clarify the process of how companies that have introduced corporate accelerator program recognize the relationship between the program period and the results of business co-creation, and how they make decisions about the program period. We conducted a case study of several companies that have introduced corporate accelerator program in Japan. In addition, this paper established a hypothesis about decision-making about the time for exploration from case studies. en-copyright= kn-copyright= en-aut-name=SHIMIZUTakeshi en-aut-sei=SHIMIZU en-aut-mei=Takeshi kn-aut-name=Žu…•Žj kn-aut-sei=Žu… kn-aut-mei=•Žj aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems Okayama University kn-affil=‘—§‘åŠw–@l‰ªŽR‘åŠwŠwpŒ¤‹†‰@ƒwƒ‹ƒXƒVƒXƒeƒ€“‡‰ÈŠwŒ¤‹†Šwˆæ en-keyword=corporate accelerator program kn-keyword=corporate accelerator program en-keyword=co-creation kn-keyword=co-creation en-keyword=exploration kn-keyword=exploration en-keyword=Time Compression Diseconomies kn-keyword=Time Compression Diseconomies END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue=1 article-no= start-page=75 end-page=99 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=The best constant of the Sobolev inequality corresponding to a bending problem of a string with a rectangular spring constant en-subtitle= kn-subtitle= en-abstract= kn-abstract=The Sobolev inequality shows that the supremum of a function defined on a whole line is estimated from the above by constant multiples of the potential energy.

It is known that the reconstruction conditions of CT images affect the analysis results when performing radiomic analysis. The aim of this study is to investigate the effect of QIR intensity on image quality and radiomic analysis of renal cell carcinoma (RCC).
Materials and Methods:The QIR intensities were selected as off, 2 and 4. The image quality evaluation items considered were task-based transfer function (TTF), noise power spectrum (NPS), and low-contrast object specific contrast-to-noise ratio (CNRLO). The influence on radiomic analysis was assessed using the discrimination accuracy of clear cell RCC.
Results:For image quality evaluation, TTF and NPS values were lower and CNRLO values were higher with increasing QIR intensity; for radiomic analysis, sensitivity, specificity, and accuracy were higher with increasing QIR intensity. Principal component analysis and receiver operating characteristics analysis also showed higher values with increasing QIR intensity.
Conclusion:It was confirmed that the intensity of the QIR intensity affects both the image quality and the radiomic analysis. en-copyright= kn-copyright= en-aut-name=OhataMiyu en-aut-sei=Ohata en-aut-mei=Miyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukuiRyohei en-aut-sei=Fukui en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorimitsuYusuke en-aut-sei=Morimitsu en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KobayashiDaichi en-aut-sei=Kobayashi en-aut-mei=Daichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamauchiTakatsugu en-aut-sei=Yamauchi en-aut-mei=Takatsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AkagiNoriaki en-aut-sei=Akagi en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HondaMitsugi en-aut-sei=Honda en-aut-mei=Mitsugi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HayashiAiko en-aut-sei=Hayashi en-aut-mei=Aiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HasegawaKoshi en-aut-sei=Hasegawa en-aut-mei=Koshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KidaKatsuhiro en-aut-sei=Kida en-aut-mei=Katsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=GotoSachiko en-aut-sei=Goto en-aut-mei=Sachiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Division of Radiological Technology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Division of Radiological Technology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Division of Radiological Technology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Division of Radiological Technology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Division of Radiological Technology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Radiology, Hiroshima University Hospital kn-affil= affil-num=9 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical, Okayama University kn-affil= en-keyword=Image quality kn-keyword=Image quality en-keyword=photon-counting computed tomography kn-keyword=photon-counting computed tomography en-keyword=quantum iterative reconstruction kn-keyword=quantum iterative reconstruction en-keyword=radiomics kn-keyword=radiomics en-keyword=renal cell carcinoma kn-keyword=renal cell carcinoma END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=3 article-no= start-page=143 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=A Hair Drawing Evaluation Algorithm for Exactness Assessment Method in Portrait Drawing Learning Assistant System en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, portrait drawing has become increasingly popular as a means of developing artistic skills and nurturing emotional expression. However, it is challenging for novices to start learning it, as they usually lack a solid grasp of proportions and structural foundations of the five senses. To address this problem, we have studied Portrait Drawing Learning Assistant System (PDLAS) for guiding novices by providing auxiliary lines of facial features, generated by utilizing OpenPose and OpenCV libraries. For PDLAS, we have also presented the exactness assessment method to evaluate drawing accuracy using the Normalized Cross-Correlation (NCC) algorithm. It calculates the similarity score between the drawing result and the initial portrait photo. Unfortunately, the current method does not assess the hair drawing, although it occupies a large part of a portrait and often determines its quality. In this paper, we present a hair drawing evaluation algorithm for the exactness assessment method to offer comprehensive feedback to users in PDLAS. To emphasize hair lines, this algorithm extracts the texture of the hair region by computing the eigenvalues and eigenvectors of the hair image. For evaluations, we applied the proposal to drawing results by seven students from Okayama University, Japan and confirmed the validity. In addition, we observed the NCC score improvement in PDLAS by modifying the face parts with low similarity scores from the exactness assessment method. en-copyright= kn-copyright= en-aut-name=ZhangYue en-aut-sei=Zhang en-aut-mei=Yue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FebriantiErita Cicilia en-aut-sei=Febrianti en-aut-mei=Erita Cicilia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SudarsonoAmang en-aut-sei=Sudarsono en-aut-mei=Amang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HsuChenchien en-aut-sei=Hsu en-aut-mei=Chenchien kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Electrical Engineering, Politeknik Elektronika Negeri Surabaya kn-affil= affil-num=4 en-affil=Department of Electrical Engineering, Politeknik Elektronika Negeri Surabaya kn-affil= affil-num=5 en-affil=Department of Electrical Engineering, National Taiwan Normal University kn-affil= en-keyword=portrait drawing kn-keyword=portrait drawing en-keyword=auxiliary lines kn-keyword=auxiliary lines en-keyword=OpenPose kn-keyword=OpenPose en-keyword=OpenCV kn-keyword=OpenCV en-keyword=normalized cross-correlation (NCC) kn-keyword=normalized cross-correlation (NCC) en-keyword=hair texture kn-keyword=hair texture en-keyword=exactness assessment method kn-keyword=exactness assessment method END start-ver=1.4 cd-journal=joma no-vol=96 cd-vols= no-issue=3 article-no= start-page=033907 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of density measurement at high pressure and high temperature using the x-ray absorption method combined with laser-heated diamond anvil cell en-subtitle= kn-subtitle= en-abstract= kn-abstract=The densities of liquid materials at high pressures and high temperatures are important information to understand the elastic behavior of liquids at extreme conditions, which is closely related to the formation and evolution processes of the Earth and planetary interiors. 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 ƒÊm 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-aut-name=NishiiNaoko en-aut-sei=Nishii en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawaiTomoko en-aut-sei=Kawai en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuokaHiroki en-aut-sei=Yasuoka en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AbeTadashi en-aut-sei=Abe en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TatsumiNanami en-aut-sei=Tatsumi en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HaradaYuika en-aut-sei=Harada en-aut-mei=Yuika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyajiTakaaki en-aut-sei=Miyaji en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=LiShunai en-aut-sei=Li en-aut-mei=Shunai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TsukanoMoemi en-aut-sei=Tsukano en-aut-mei=Moemi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=OgawaDaisuke en-aut-sei=Ogawa en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TakeiKohji en-aut-sei=Takei en-aut-mei=Kohji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=YamadaHiroshi en-aut-sei=Yamada en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cell Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neuroscience, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neuroscience, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neuroscience, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Genomics and Proteomics, Advanced Science Research Center, Okayama University kn-affil= affil-num=7 en-affil=Department of Genomics and Proteomics, Advanced Science Research Center, Okayama University kn-affil= affil-num=8 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Central Research Laboratory, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Neuroscience, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Neuroscience, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=VGLUT3 kn-keyword=VGLUT3 en-keyword=glutamate kn-keyword=glutamate en-keyword=podocyte kn-keyword=podocyte en-keyword=glutamatergic transmission kn-keyword=glutamatergic transmission END start-ver=1.4 cd-journal=joma no-vol=301 cd-vols= no-issue=4 article-no= start-page=108334 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=Roles of basic amino acid residues in substrate binding and transport of the light-driven anion pump Synechocystis halorhodopsin (SyHR) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Microbial rhodopsins are photoreceptive seventransmembrane a-helical proteins, many of which function as ion transporters, primarily for small monovalent ions such as Na+, K+, Cl-, Br-, and I-. Synechocystis halorhodopsin (SyHR), identified from the cyanobacterium Synechocystis sp. PCC 7509, uniquely transports the polyatomic divalent SO42- inward, in addition to monovalent anions (Cl- and Br-). In this study, we conducted alanine-scanning mutagenesis on twelve basic amino acid residues to investigate the anion transport mechanism of SyHR. We quantitatively evaluated the Cl-and SO42- transport activities of the WT SyHR and its mutants. The results showed a strong correlation between the Cl-and SO42- transport activities among them (R = 0.94), suggesting a shared pathway for both anions. Notably, the R71A mutation selectively abolished SO42- transport activity while maintaining Cl- transport, whereas the H167A mutation significantly impaired both Cl-and SO42- transport. Furthermore, spectroscopic analysis revealed that the R71A mutant lost its ability to bind SO42- due to the absence of a positive charge, while the H167A mutant failed to accumulate the O intermediate during the photoreaction cycle (photocycle) due to reduced hydrophilicity. Additionally, computational analysis revealed the SO42- binding modes and clarified the roles of residues involved in its binding around the retinal chromophore. Based on these findings and previous structural information, we propose that the positive charge and hydrophilicity of Arg71 and His167 are crucial for the formation of the characteristic initial and transient anion-binding site of SyHR, enabling its unique ability to bind and transport both Cl-and SO42-. en-copyright= kn-copyright= en-aut-name=NakamaMasaki en-aut-sei=Nakama en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NojiTomoyasu en-aut-sei=Noji en-aut-mei=Tomoyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KojimaKeiichi en-aut-sei=Kojima en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshizawaSusumu en-aut-sei=Yoshizawa en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshikitaHiroshi en-aut-sei=Ishikita en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SudoYuki en-aut-sei=Sudo en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Applied Chemistry, The University of Tokyo kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Atmosphere and Ocean Research Institute, The University of Tokyo kn-affil= affil-num=5 en-affil=Department of Applied Chemistry, The University of Tokyo kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=microbial rhodopsin kn-keyword=microbial rhodopsin en-keyword=anion transport kn-keyword=anion transport en-keyword=retinal kn-keyword=retinal en-keyword=membrane protein kn-keyword=membrane protein en-keyword=photobiology kn-keyword=photobiology END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=3 article-no= start-page=124 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=Facial Privacy Protection with Dynamic Multi-User Access Control for Online Photo Platforms en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the digital age, sharing moments through photos has become a daily habit. However, every face captured in these photos is vulnerable to unauthorized identification and potential misuse through AI-powered synthetic content generation. Previously, we introduced SnapSafe, a secure system for enabling selective image privacy focusing on facial regions for single-party scenarios. Recognizing that group photos with multiple subjects are a more common scenario, we extend SnapSafe to support multi-user facial privacy protection with dynamic access control designed for online photo platforms. Our approach introduces key splitting for access control, an owner-centric permission system for granting and revoking access to facial regions, and a request-based mechanism allowing subjects to initiate access permissions. These features ensure that facial regions remain protected while maintaining the visibility of non-facial content for general viewing. To ensure reproducibility and isolation, we implemented our solution using Docker containers. Our experimental assessment covered diverse scenarios, categorized as "Single", "Small", "Medium", and "Large", based on the number of faces in the photos. The results demonstrate the system's effectiveness across all test scenarios, consistently performing face encryption operations in under 350 ms and achieving average face decryption times below 286 ms across various group sizes. The key-splitting operations maintained a 100% success rate across all group configurations, while revocation operations were executed efficiently with server processing times remaining under 16 ms. These results validate the system's capability in managing facial privacy while maintaining practical usability in online photo sharing contexts. en-copyright= kn-copyright= en-aut-name=SantosoAndri en-aut-sei=Santoso en-aut-mei=Andri 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=KoderaYuta en-aut-sei=Kodera en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Green Innovation Center, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=facial privacy protection kn-keyword=facial privacy protection en-keyword=selective facial encryption kn-keyword=selective facial encryption en-keyword=multi-user access control kn-keyword=multi-user access control en-keyword=deep-learning applications kn-keyword=deep-learning applications en-keyword=online photo platform kn-keyword=online photo platform END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue= article-no= start-page=670 end-page=679 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photochemically assisted synthesis of phenacenes fluorinated at the terminal benzene rings and their electronic spectra en-subtitle= kn-subtitle= en-abstract= kn-abstract=[n]Phenacenes ([n] = 5-7), octafluorinated at the terminal benzene rings (F8-phenacenes: F8PIC, F8FUL, and F87PHEN), were photochemically synthesized, and their electronic spectra were investigated to reveal the effects of the fluorination on the electronic features of phenacene molecules. F8-Phenacenes were conveniently synthesized by the Mallory photoreaction of the corresponding fluorinated diarylethenes as the key step. Upon fluorination on the phenacene cores, the absorption and fluorescence bands of the F8-phenacenes in CHCl3 systematically red-shifted by ca. 3-5 nm compared to those of the corresponding parent phenacenes. The vibrational progressions of the absorption and fluorescence bands were little affected by the fluorination in the solution phase. In the solid state, the absorption band of F8-phenacenes appeared in the similar wavelength region for the corresponding parent phenacenes whereas their fluorescence bands markedly red-shifted and broadened. These observations suggest that the intermolecular interactions of excited-state F8-phenacene molecules are significantly different from those of the corresponding parent molecules, most likely due to different crystalline packing motifs. en-copyright= kn-copyright= en-aut-name=IshiiYuuki en-aut-sei=Ishii en-aut-mei=Yuuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamajiMinoru en-aut-sei=Yamaji en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TaniFumito en-aut-sei=Tani en-aut-mei=Fumito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GotoKenta en-aut-sei=Goto en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KubozonoYoshihiro en-aut-sei=Kubozono en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkamotoHideki en-aut-sei=Okamoto en-aut-mei=Hideki 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=Division of Molecular Science, Graduate School of Science and Engineering, Gunma University kn-affil= affil-num=3 en-affil=Institute for Materials Chemistry and Engineering, Kyushu University kn-affil= affil-num=4 en-affil=Institute for Materials Chemistry and Engineering, Kyushu University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=fluorescence kn-keyword=fluorescence en-keyword=fluorinated aromatics kn-keyword=fluorinated aromatics en-keyword=phenacene kn-keyword=phenacene en-keyword=photoreaction kn-keyword=photoreaction END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=6 article-no= start-page=668 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Robustness of Machine Learning Predictions for Determining Whether Deep Inspiration Breath-Hold Is Required in Breast Cancer Radiation Therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Deep inspiration breath-hold (DIBH) is a commonly used technique to reduce the mean heart dose (MHD), which is critical for minimizing late cardiac side effects in breast cancer patients undergoing radiation therapy (RT). Although previous studies have explored the potential of machine learning (ML) to predict which patients might benefit from DIBH, none have rigorously assessed ML model performance across various MHD thresholds and parameter settings. This study aims to evaluate the robustness of ML models in predicting the need for DIBH across different clinical scenarios. Methods: Using data from 207 breast cancer patients treated with RT, we developed and tested ML models at three MHD cut-off values (240, 270, and 300 cGy), considering variations in the number of independent variables (three vs. six) and folds in the cross-validation (three, four, and five). Robustness was defined as achieving high F2 scores and low instability in predictive performance. Results: Our findings indicate that the decision tree (DT) model demonstrated consistently high robustness at 240 and 270 cGy, while the random forest model performed optimally at 300 cGy. At 240 cGy, a threshold critical to minimize late cardiac risks, the DT model exhibited stable predictive power, reducing the risk of overestimating DIBH necessity. Conclusions: These results suggest that the DT model, particularly at lower MHD thresholds, may be the most reliable for clinical applications. By providing a tool for targeted DIBH implementation, this model has the potential to enhance patient-specific treatment planning and improve clinical outcomes in RT. en-copyright= kn-copyright=

Performance for Head and Neck Tumors with Simple Diffusion Kurtosis Imaging and Machine Learning Bi-Parameter Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Mean kurtosis (MK) values in simple diffusion kurtosis imaging (SDI)-a type of diffusion kurtosis imaging (DKI)-have been reported to be useful in the diagnosis of head and neck malignancies, for which pre-processing with smoothing filters has been reported to improve the diagnostic accuracy. Multi-parameter analysis using DKI in combination with other image types has recently been reported to improve the diagnostic performance. The purpose of this study was to evaluate the usefulness of machine learning (ML)-based multi-parameter analysis using the MK and apparent diffusion coefficient (ADC) values-which can be acquired simultaneously through SDI-for the differential diagnosis of benign and malignant head and neck tumors, which is important for determining the treatment strategy, as well as examining the usefulness of filter pre-processing. Methods: A total of 32 pathologically diagnosed head and neck tumors were included in the study, and a Gaussian filter was used for image pre-processing. MK and ADC values were extracted from pixels within the tumor area and used as explanatory variables. Five ML algorithms were used to create models for the prediction of tumor status (benign or malignant), which were evaluated through ROC analysis. Results: Bi-parameter analysis with gradient boosting achieved the best diagnostic performance, with an AUC of 0.81. Conclusions: The usefulness of bi-parameter analysis with ML methods for the differential diagnosis of benign and malignant head and neck tumors using SDI data were demonstrated. en-copyright=

kn-abstract=Pb-substituted La(O, F)BiS2 (Pb-LaOFBiS2) exhibits improved superconducting properties and a resistivity anomaly around 100 K that is attributed to a structural transition. We have performed temperature(T)-dependent photoelectron holography (PEH) to study dopant incorporation sites and the local structure change across the anomaly. The PEH study of Pb-LaOFBiS2 provided evidence for the dominant incorporation sites of Pb and F: Pb atoms are incorporated into the Bi sites and F atoms are incorporated into the O site. No remarkable difference in the local structures around Pb and Bi atoms was observed. Across the temperature of the resistivity anomaly (T*), photoelectron holograms of Bi 4f changed. Comparisons of holograms with those of non-substituted LaOFBiS2 sample, as well as simulated holograms, suggested that (1), above T*, the tetragonal structure of Pb-LaOFBiS2 is different from the tetragonal structure of LaOFBiS2 and (2), below T*, the tetragonal structure still remains in Pb-LaOFBiS2. We discuss a possible origin of the difference in the structure above T* and the implication of the result below T*, which are necessary ingredients to understand the physical properties of Pb-LaOFBiS2. en-copyright= kn-copyright= en-aut-name=LiYajun en-aut-sei=Li en-aut-mei=Yajun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HashimotoYusuke en-aut-sei=Hashimoto en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KataokaNoriyuki en-aut-sei=Kataoka en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SunZexu en-aut-sei=Sun en-aut-mei=Zexu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawamuraSota en-aut-sei=Kawamura en-aut-mei=Sota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TomitaHiroto en-aut-sei=Tomita en-aut-mei=Hiroto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SetoguchiTaro en-aut-sei=Setoguchi en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakeuchiSoichiro en-aut-sei=Takeuchi en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KogaShunjo en-aut-sei=Koga en-aut-mei=Shunjo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YamagamiKohei en-aut-sei=Yamagami en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KotaniYoshinori en-aut-sei=Kotani en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=DemuraSatoshi en-aut-sei=Demura en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=NoguchiKanako en-aut-sei=Noguchi en-aut-mei=Kanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=SakataHideaki en-aut-sei=Sakata en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=MatsushitaTomohiro en-aut-sei=Matsushita en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=WakitaTakanori en-aut-sei=Wakita en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=MuraokaYuji en-aut-sei=Muraoka en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=YokoyaTakayoshi en-aut-sei=Yokoya en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Nara Institute of Science and Technology (NAIST) kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Nara Institute of Science and Technology (NAIST) kn-affil= affil-num=5 en-affil=Nara Institute of Science and Technology (NAIST) kn-affil= affil-num=6 en-affil=Nara Institute of Science and Technology (NAIST) kn-affil= affil-num=7 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Nara Institute of Science and Technology (NAIST) kn-affil= affil-num=9 en-affil=Nara Institute of Science and Technology (NAIST) kn-affil= affil-num=10 en-affil=Japan Synchrotron Radiation Research Institute (JASRI) kn-affil= affil-num=11 en-affil=Japan Synchrotron Radiation Research Institute (JASRI) kn-affil= affil-num=12 en-affil=Department of Physics, College of Science and Technology(CST), Nihon University kn-affil= affil-num=13 en-affil=Tokyo University of Science kn-affil= affil-num=14 en-affil=Tokyo University of Science kn-affil= affil-num=15 en-affil=Nara Institute of Science and Technology (NAIST) kn-affil= affil-num=16 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=17 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=18 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=85 cd-vols= no-issue=6 article-no= start-page=1082 end-page=1096 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=Myeloid Cells Induce Infiltration and Activation of B Cells and CD4+ T Follicular Helper Cells to Sensitize Brain Metastases to Combination Immunotherapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Brain metastasis is a poor prognostic factor in patients with cancer. Despite showing efficacy in many extracranial tumors, immunotherapy with anti?PD-1 mAb or anti?CTLA4 mAb seems to be less effective against intracranial tumors. Promisingly, recent clinical studies have reported that combination therapy with anti?PD-1 and anti?CTLA4 mAbs has a potent antitumor effect on brain metastasis, highlighting the need to elucidate the detailed mechanisms controlling the intracranial tumor microenvironment (TME) to develop effective immunotherapeutic strategies. In this study, we analyzed the tumor-infiltrating lymphocytes in murine models of brain metastasis that responded to anti?CTLA4 and anti?PD-1 mAbs. Activated CD4+ T follicular helper (TFH) cells with high CTLA4 expression characteristically infiltrated the intracranial TME, which were activated by combination anti?CTLA4 and anti?PD-1 treatment. The loss of TFH cells suppressed the additive effect of CTLA4 blockade on anti?PD-1 mAb. B-cell?activating factor belonging to the TNF family (BAFF) and a proliferation-inducing ligand (APRIL) produced by abundant myeloid cells, particularly CD80hiCD206lo proinflammatory M1-like macrophages, in the intracranial TME induced B-cell and TFH-cell infiltration and activation. Furthermore, the intracranial TME of patients with non?small cell lung cancer featured TFH- and B-cell infiltration as tertiary lymphoid structures. Together, these findings provide insights into the immune cell cross-talk in the intracranial TME that facilitates an additive antitumor effect of CTLA4 blockade with anti?PD-1 treatment, supporting the potential of a combination immunotherapeutic strategy for brain metastases.
Significance: B-cell and CD4+ T follicular helper cell activation via BAFF/APRIL from abundant myeloid cells in the intracranial tumor microenvironment enables a combinatorial effect of CTLA4 and PD-1 blockade in brain metastases. en-copyright= kn-copyright= en-aut-name=NinomiyaToshifumi en-aut-sei=Ninomiya en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

thermospermine-responsive uORF-containing mRNAs by ribosomal mutations in Arabidopsis thaliana en-subtitle= kn-subtitle= en-abstract= kn-abstract=Auxin-induced xylem formation in angiosperms is negatively regulated by thermospermine, whose biosynthesis is also induced by auxin. In Arabidopsis thaliana, loss-of-function mutants of ACL5, which encodes thermospermine synthase, exhibit a dwarf phenotype accompanied by excessive xylem formation. Studies of suppressor mutants that recover from the acl5 dwarf phenotype suggest that thermospermine alleviates the inhibitory effect of an upstream open-reading frame (uORF) on the main ORF translation of SAC51 mRNA. Many suppressor mutations for acl5 have been mapped to the uORF conserved in the SAC51 family or to ribosomal protein genes, such as RPL10A, RPL4A, and RACK1A. In this study, we identified newly isolated acl5 suppressors, sac501, sac504, and sac506, which are additional alleles of RPL10A and the uORFs of SAC51 family members, SACL1 and SACL3, respectively. To investigate whether acl5-suppressor alleles of ribosomal genes broadly affect translation of uORF-containing mRNAs, we examined GUS activity in several 5'-GUS fusion constructs. Our results showed that these alleles enhanced GUS activity in SAC51 and SACL3 5'-fusion constructs but had no effect on other 5'-fusion constructs unrelated to thermospermine response. This suggests that these ribosomal proteins are specifically involved in the thermospermine-mediated regulation of mRNA translation. en-copyright= kn-copyright= en-aut-name=MutsudaKoki en-aut-sei=Mutsuda en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiiYuichi en-aut-sei=Nishii en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ToyoshimaTomohiko en-aut-sei=Toyoshima en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukushimaHiroko en-aut-sei=Fukushima en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MotoseHiroyasu en-aut-sei=Motose en-aut-mei=Hiroyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakahashiTaku en-aut-sei=Takahashi en-aut-mei=Taku 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=mRNA translation kn-keyword=mRNA translation en-keyword=RPL10 kn-keyword=RPL10 en-keyword=suppressor mutant kn-keyword=suppressor mutant en-keyword=thermospermine kn-keyword=thermospermine en-keyword=uORF kn-keyword=uORF 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=20250312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Droplet Impact Behavior on Convex Surfaces with a Circumferential Wettability Difference en-subtitle= kn-subtitle= en-abstract= kn-abstract=Controlling the bouncing behavior of the impacting droplets is an important issue for splay cooling, icing prevention, and other applications. The bouncing behavior of impacting droplets on superhydrophobic curved surfaces and flat substrates with a wettability difference has been widely investigated, and droplets impacting these surfaces show shorter contact times than those on superhydrophobic flat surfaces and droplet transport. However, there have been few studies on the droplet impact behavior on curved surfaces with a wettability difference, where efficient droplet control could be achieved by combining the features. In the present study, droplet impact experiments were conducted using copper cylinders with different circumferential wettabilities from hydrophilic to superhydrophobic, varying the impact velocity, cylinder diameter, and rotation angle. Droplets that impacted the wettability boundary showed asymmetric deformation and moved to the hydrophilic side, owing to the driving force of the wettability difference. Moreover, the droplet behavior was classified into four types: the droplet bounced off the surface, the droplet bounced off the surface and split, the droplet attached to the surface, and the droplet attached to the surface and split. The droplet behavior was estimated by using the maximum spreading width of the droplet impacted on the flat substrate. We evaluated whether the droplets attached to the surface or bounced off the surface after impact using the Weber number and rotation angle, and the estimations were in agreement with the experimental results for cylinder diameters of 4 and 6 mm. en-copyright= kn-copyright= en-aut-name=IshikawaTaku en-aut-sei=Ishikawa en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamadaYutaka en-aut-sei=Yamada en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IsobeKazuma en-aut-sei=Isobe en-aut-mei=Kazuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HoribeAkihiko en-aut-sei=Horibe en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=1757 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Keratinocyte-driven dermal collagen formation in the axolotl skin en-subtitle= kn-subtitle= en-abstract= kn-abstract=Type I collagen is a major component of the dermis and is formed by dermal fibroblasts. The development of dermal collagen structures has not been fully elucidated despite the major presence and importance of the dermis. This lack of understanding is due in part to the opacity of mammalian skin and it has been an obstacle to cosmetic and medical developments. We reveal the process of dermal collagen formation using the highly transparent skin of the axolotl and fluorescent collagen probes. We clarify that epidermal cells, not dermal fibroblasts, contribute to dermal collagen formation. Mesenchymal cells (fibroblasts) play a role in modifying the collagen fibers already built by keratinocytes. We confirm that collagen production by keratinocytes is a widely conserved mechanism in other model organisms. Our findings warrant a change in the current consensus about dermal collagen formation and could lead to innovations in cosmetology and skin medication. en-copyright= kn-copyright= en-aut-name=OhashiAyaka en-aut-sei=Ohashi en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakamotoHirotaka en-aut-sei=Sakamoto en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurodaJunpei en-aut-sei=Kuroda en-aut-mei=Junpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KondoYohei en-aut-sei=Kondo en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KameiYasuhiro en-aut-sei=Kamei en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NonakaShigenori en-aut-sei=Nonaka en-aut-mei=Shigenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FurukawaSaya en-aut-sei=Furukawa en-aut-mei=Saya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamamotoSakiya en-aut-sei=Yamamoto en-aut-mei=Sakiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SatohAkira en-aut-sei=Satoh en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Frontier Biosciences, Osaka University kn-affil= affil-num=4 en-affil=Center for One Medicine Innovative Translational Research (COMIT), Nagoya University kn-affil= affil-num=5 en-affil=Laboratory for Biothermology, National Institute for Basic Biology kn-affil= affil-num=6 en-affil=The Graduate University for Advanced Studies (SOKENDAI) kn-affil= affil-num=7 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=9 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=20160908 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=S-nitrosylation of laforin inhibits its phosphatase activity and is implicated in Lafora disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recently, the relation between S-nitrosylation by nitric oxide (NO), which is over?produced under pathological conditions and neurodegenerative diseases, includingAlzheimerfs and Parkinsonfs diseases, has become a focus of attention. Although mostcases of Parkinsonfs disease are known to be caused by mutations in the Parkin gene, arecent finding has indicated that S-nitrosylation of Parkin affects its enzymatic activityand leads to the Parkinsonian phenotype. Therefore, it is important to understand thefunction of S-nitrosylated proteins in the pathogenesis of neurodegenerative diseases.Lafora disease (LD, OMIM 254780) is a neurodegenerative disease characterized by theaccumulation of insoluble glucans called Lafora bodies (LBs). LD is caused by mutationsin genes that encode the glucan phosphatase, Laforin, or the E3 ubiquitin ligase, Malin.In this study, we hypothesized that LD may be caused by S-nitrosylation of Laforin,which is similar to the finding that Parkinsonfs disease is caused by S-nitrosylation ofParkin. To test this hypothesis, we first determined whether Laforin was S-nitrosylatedusing a biotin switch assay, and compared the three main functions of unmodified andS-nitrosylated Laforin, namely glucan- and Malin-binding activity and phosphataseactivity. Furthermore, we examined whether the numbers of LBs were changed byNO in the cells expressing wild-type Laforin. Here, we report for the first time thatS-nitrosylation of Laforin inhibited its phosphatase activity and that LB formation wasincreased by an NO donor. Our results suggest a possible hypothesis for LD pathogenesis; that is, the decrease in phosphatase activity of Laforin by S-nitrosylation leads toincreased LB formation. Therefore, LD may be caused not only by mutations in theLaforin or Malin genes, but also by the S-nitrosylation of Laforin. en-copyright= kn-copyright= en-aut-name=ToyotaRikako en-aut-sei=Toyota en-aut-mei=Rikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HonjoYasuko en-aut-sei=Honjo en-aut-mei=Yasuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ImajoRisa en-aut-sei=Imajo en-aut-mei=Risa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University; Research Institute for Radiation Biology and Medicine, Hiroshima University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University; Research Institute for Radiation Biology and Medicine, Hiroshima University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University; Research Institute for Radiation Biology and Medicine, Hiroshima University kn-affil= en-keyword=S-Nitrosylation Of Laforin kn-keyword=S-Nitrosylation Of Laforin en-keyword=Post-Translational Modification kn-keyword=Post-Translational Modification en-keyword=Nitrosylation kn-keyword=Nitrosylation en-keyword=Phosphatase kn-keyword=Phosphatase en-keyword=Glucan-Binding kn-keyword=Glucan-Binding 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 fieldfs 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=210 cd-vols= no-issue= article-no= start-page=112952 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=A microfluidic paper-based analytical device that uses gelatin film to assay protease activity via time readout en-subtitle= kn-subtitle= en-abstract= kn-abstract=Food processing, detergents, and pharmaceuticals frequently employ proteases, which are enzymes that break the chemical bonds of both proteins and peptides. In this work, we developed a microfluidic paper-based analytical device (?PAD) for protease activity assays via time readout. To accomplish this, we folded the ?PAD to form layers, then inserted a water-insoluble gelatin film between the layers of paper to form the device. Lamination helps to maintain the gelatin film between the introduction zone, which is the upper layer, and the detection channel, which is the lower layer. Proteases decompose the gelatin film when it enters the introduction zone, which then allows it to flow into the detection channel. The protease activity in the sample solution determines the time required to dissolve the gelatin film, which leads to a linear relationship between the logarithm of the protease concentration and the time required to flow the solution a specific distance on the detection channel. The ?PAD was used to measure proteases in concentrations that ranged from 0.25 to 1 mg L?1 for bromelain, 2.5 to 10 mg L?1 for papain, and 1 to 8 mg L?1 for trypsin. The limits of quantification for bromelain, papain, and trypsin were 0.41, 2.7, and 9.2 mg mL?1, respectively. The relative standard deviations for bromelain were smaller than 2 % for concentrations ranging from 0.5 to 1.0 mg L?1. We compared the ?PAD to a commercially available protease activity assay kit, which relies on quenching fluorescein isothiocyanate-labeled casein. Both methods demonstrated the same order of activity: bromelain > papain > trypsin. The proposed device allowed the assay of bromelain in both pineapple pulp and juice, which were stored at room temperature. When first using the proposed device, the bromelain in the pulp gradually lost its activity, while the activity of the bromelain in the juice showed no significant change for five days. The ?PAD requires no analytical instruments for quality control and monitoring of the protease activity in food. en-copyright= kn-copyright= en-aut-name=RenJianchao en-aut-sei=Ren en-aut-mei=Jianchao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DanchanaKaewta en-aut-sei=Danchana en-aut-mei=Kaewta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanetaTakashi en-aut-sei=Kaneta en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Chemistry, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Okayama University kn-affil= affil-num=3 en-affil=Department of Chemistry, Okayama University kn-affil= en-keyword=Microfluidic paper-based analytical device kn-keyword=Microfluidic paper-based analytical device en-keyword=Protease kn-keyword=Protease en-keyword=Enzyme assay kn-keyword=Enzyme assay en-keyword=Time readout kn-keyword=Time readout END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=25 article-no= start-page=4757 end-page=4773 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=Recent development of azahelicenes showing circularly polarized luminescence en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recently, a variety of circularly polarized luminescence (CPL) dyes have been developed as next-generation chiroptical materials. Helicenes, ortho-fused aromatics, have been recognized as some of the most promising CPL dyes. Although typical carbohelicenes show CPL, weak fluorescence is often emitted in the blue region. In contrast, heteroatom-embedded helicenes (heterohelicenes) can show intense fluorescence and CPL in the visible region because heteroatoms alter the electronic states of helicene frameworks. Among various heterohelicenes, nitrogen-embedded helicenes (azahelicenes) have unique features such as facile functionalization and sensitive responses to acid/base or metal ions. Furthermore, polycyclic aromatic hydrocarbons (PAHs) containing azaborine units have been recognized as excellent luminescent materials, and the helical derivatives, B,N-embedded helicenes, have been rapidly growing recently. In this feature article, we review and summarize the synthesis and chiroptical properties of azahelicenes, which are classified into imine-type and amine-type azahelicenes and B,N-embedded helicenes. CPL switching systems of azahelicenes are also reviewed. en-copyright= kn-copyright= en-aut-name=MaedaChihiro en-aut-sei=Maeda en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EmaTadashi en-aut-sei=Ema en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=5 article-no= start-page=2421 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Deep Reinforcement Learning for Dynamic Pricing and Ordering Policies in Perishable Inventory Management en-subtitle= kn-subtitle= en-abstract= kn-abstract=Perishable goods have a limited shelf life, and inventory should be discarded once it exceeds its shelf life. Finding optimal inventory management policies is essential since inefficient policies can lead to increased waste and higher costs. While many previous studies assume the perishable inventory is processed following the First In, First Out rule, it does not reflect customer purchasing behavior. In practice, customers' preferences are influenced by the shelf life and price of products. This study optimizes inventory and pricing policies for a perishable inventory management problem considering age-dependent probabilistic demand. However, introducing dynamic pricing significantly increases the complexity of the problem. To tackle this challenge, we propose eliminating irrational actions in dynamic programming without sacrificing optimality. To solve this problem more efficiently, we also implement a deep reinforcement learning algorithm, proximal policy optimization, to solve this problem. The results show that dynamic programming with action reduction achieved an average of 63.1% reduction in computation time compared to vanilla dynamic programming. In most cases, proximal policy optimization achieved an optimality gap of less than 10%. Sensitivity analysis of the demand model revealed a negative correlation between customer sensitivity to shelf lives or prices and total profits. en-copyright= kn-copyright= en-aut-name=NomuraYusuke en-aut-sei=Nomura en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LiuZiang en-aut-sei=Liu en-aut-mei=Ziang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishiTatsushi en-aut-sei=Nishi en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=reinforcement learning kn-keyword=reinforcement learning en-keyword=supply chain kn-keyword=supply chain en-keyword=inventory management kn-keyword=inventory management en-keyword=perishable inventory kn-keyword=perishable inventory en-keyword=dynamic pricing kn-keyword=dynamic pricing 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

utilizing generative AI chatbots to reduce psychological burden and enhance treatment engagement: a pilot study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Pediatric and adolescent/young adult (AYA) cancer patients face profound psychological challenges, exacerbated by limited access to continuous mental health support. While conventional therapeutic interventions often follow structured protocols, the potential of generative artificial intelligence (AI) chatbots to provide continuous conversational support remains unexplored. This study evaluates the feasibility and impact of AI chatbots in alleviating psychological distress and enhancing treatment engagement in this vulnerable population.
Methods: Two age-appropriate AI chatbots, leveraging GPT-4, were developed to provide natural, empathetic conversations without structured therapeutic protocols. Five pediatric and AYA cancer patients participated in a two-week intervention, engaging with the chatbots via a messaging platform. Pre- and post-intervention anxiety and stress levels were self-reported, and usage patterns were analyzed to assess the chatbots' effectiveness.
Results: Four out of five participants reported significant reductions in anxiety and stress levels post-intervention. Participants engaged with the chatbot every 2-3 days, with sessions lasting approximately 10 min. All participants noted improved treatment motivation, with 80% disclosing personal concerns to the chatbot they had not shared with healthcare providers. The 24/7 availability particularly benefited patients experiencing nighttime anxiety.
Conclusions: This pilot study demonstrates the potential of generative AI chatbots to complement traditional mental health services by addressing unmet psychological needs in pediatric and AYA cancer patients. The findings suggest these tools can serve as accessible, continuous support systems. Further large-scale studies are warranted to validate these promising results. 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=

expression in tumor vasculature contributes to therapeutic resistance to doxorubicin-PEG-liposomes in mice bearing doxorubicin-resistant B16-BL6 tumors en-subtitle= kn-subtitle= en-abstract= kn-abstract=We previously indicated that doxorubicin (DOX)-loaded polyethylene glycol (PEG)-modified liposomes (DOX-PEG-liposomes) were therapeutically effective in mice bearing DOX-resistant colon-26 (C26/DOX) tumors, and the efficacy was comparable in mice bearing DOX-sensitive C26 tumors. However, in the current study, DOX-PEG-liposomes exerted no therapeutic activity in DOX-resistant B16-BL6 melanoma (B16/DOX)-bearing mice, although they significantly suppressed DOX-sensitive B16 tumor growth in mice. Although we previously reported that the anti-tumor effects in C26/DOX-bearing mice were derived from the cytotoxic effects of DOX on vascular endothelial cells (VECs) in tumors, the B16/DOX tumor vasculature was not substantially damaged after administration of DOX-PEG-liposomes. In B16/DOX tumors, P-gp expression was significantly induced in the VECs, but not in the C26/DOX tumors, indicating that the high expression of P-gp in the tumor vasculature would be responsible for the lack of therapeutic effect of DOX-PEG-liposomes in B16/DOX-bearing mice. Epidermal growth factor (EGF), a possible induction factor for P-gp expression, was highly expressed in B16/DOX cells and tumor tissues, and significantly induced P-gp expression in human umbilical vein endothelial cells (HUVEC). The EGF receptor (EGFR) was also highly expressed in B16/DOX tumor VECs, suggesting that the activation of EGF/EGFR signaling may induce P-gp expression in VECs in B16/DOX tumors. 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=UedaTomoki en-aut-sei=Ueda en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IenakaYusuke en-aut-sei=Ienaka en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TojoHaruka en-aut-sei=Tojo en-aut-mei=Haruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HyodoKenji en-aut-sei=Hyodo en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 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=Eisai Co., Ltd. kn-affil= affil-num=6 en-affil=Laboratory of Pharmaceutics, Kobe Pharmaceutical University kn-affil= affil-num=7 en-affil=Department of Pharmaceutics, Faculty of Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Drug resistance kn-keyword=Drug resistance en-keyword=P-glycoprotein kn-keyword=P-glycoprotein en-keyword=Liposome kn-keyword=Liposome en-keyword=Tumor vascular endothelial cells kn-keyword=Tumor vascular endothelial cells en-keyword=Melanoma kn-keyword=Melanoma 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-ƒÀ (TGF-ƒÀ), an activator of CAFs, in tumor tissues, suggesting that the reduction in TGF-ƒÀ 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=15 cd-vols= no-issue=1 article-no= start-page=6666 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Microfluidic fabrication of rattle shaped biopolymer microcapsules via sequential phase separation in oil droplets en-subtitle= kn-subtitle= en-abstract= kn-abstract=Multilayer microcapsules containing a small particle within a larger capsule have recently attracted considerable attention owing to their potential applications in diverse fields, including drug delivery, active ingredient storage, and chemical reactions. These complex capsules have been fabricated using interfacial polymerization or seeded emulsion polymerization. However, these methods often require complex and lengthy polymerization processes, limiting their utility, particularly in biopolymer systems. This study introduces a simple and efficient approach for preparing rattle-shaped cellulose acetate (CA) microcapsules through sequential phase separation in droplets. We systematically examine the effects of various preparation parameters, including the amount of co-solvent, initial droplet size, and flow rates, and reveal that the incorporation of a co-solvent-ethyl acetate (EA)- in the dispersed phase significantly impacts the microcapsule morphology. Our findings demonstrate a transition from a core-shell to a rattle-shaped structure as the EA concentration increases. Furthermore, the initial droplet diameter and flow rates influence microcapsule formation-larger droplets and reduced continuous-phase flow rates favor the development of multi-layered structures. These results indicate that the formation mechanism of these rattle-shaped microcapsules arises from the establishment of a radial solvent concentration gradient and subsequent phase separation within the droplets, driven by kinetic rather than thermodynamic factors. en-copyright= kn-copyright= en-aut-name=WatanabeTakaichi en-aut-sei=Watanabe en-aut-mei=Takaichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakaiYuko en-aut-sei=Sakai en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoriKurumi en-aut-sei=Mori en-aut-mei=Kurumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OnoTsutomu en-aut-sei=Ono en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= affil-num=2 en-affil=Department of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= affil-num=3 en-affil=Department of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= affil-num=4 en-affil=Department of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= en-keyword=Microfluidics kn-keyword=Microfluidics en-keyword=Phase separation kn-keyword=Phase separation en-keyword=Nucleation kn-keyword=Nucleation en-keyword=Multi-core kn-keyword=Multi-core en-keyword=Rattle-shaped kn-keyword=Rattle-shaped END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=2 article-no= start-page=217 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250121 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Interchangeability of Cross-Platform Orthophotographic and LiDAR Data in DeepLabV3+-Based Land Cover Classification Method en-subtitle= kn-subtitle= en-abstract= kn-abstract=Riverine environmental information includes important data to collect, and the data collection still requires personnel's field surveys. These on-site tasks still face significant limitations (i.e., hard or danger to entry). In recent years, as one of the efficient approaches for data collection, air-vehicle-based Light Detection and Ranging technologies have already been applied in global environmental research, i.e., land cover classification (LCC) or environmental monitoring. For this study, the authors specifically focused on seven types of LCC (i.e., bamboo, tree, grass, bare ground, water, road, and clutter) that can be parameterized for flood simulation. A validated airborne LiDAR bathymetry system (ALB) and a UAV-borne green LiDAR System (GLS) were applied in this study for cross-platform analysis of LCC. Furthermore, LiDAR data were visualized using high-contrast color scales to improve the accuracy of land cover classification methods through image fusion techniques. If high-resolution aerial imagery is available, then it must be downscaled to match the resolution of low-resolution point clouds. Cross-platform data interchangeability was assessed by comparing the interchangeability, which measures the absolute difference in overall accuracy (OA) or macro-F1 by comparing the cross-platform interchangeability. It is noteworthy that relying solely on aerial photographs is inadequate for achieving precise labeling, particularly under limited sunlight conditions that can lead to misclassification. In such cases, LiDAR plays a crucial role in facilitating target recognition. All the approaches (i.e., low-resolution digital imagery, LiDAR-derived imagery and image fusion) present results of over 0.65 OA and of around 0.6 macro-F1. The authors found that the vegetation (bamboo, tree, grass) and road species have comparatively better performance compared with clutter and bare ground species. Given the stated conditions, differences in the species derived from different years (ALB from year 2017 and GLS from year 2020) are the main reason. Because the identification of clutter species includes all the items except for the relative species in this research, RGB-based features of the clutter species cannot be substituted easily because of the 3-year gap compared with other species. Derived from on-site reconstruction, the bare ground species also has a further color change between ALB and GLS that leads to decreased interchangeability. In the case of individual species, without considering seasons and platforms, image fusion can classify bamboo and trees with higher F1 scores compared to low-resolution digital imagery and LiDAR-derived imagery, which has especially proved the cross-platform interchangeability in the high vegetation types. In recent years, high-resolution photography (UAV), high-precision LiDAR measurement (ALB, GLS), and satellite imagery have been used. LiDAR measurement equipment is expensive, and measurement opportunities are limited. Based on this, it would be desirable if ALB and GLS could be continuously classified by Artificial Intelligence, and in this study, the authors investigated such data interchangeability. A unique and crucial aspect of this study is exploring the interchangeability of land cover classification models across different LiDAR platforms. en-copyright= kn-copyright= en-aut-name=PanShijun en-aut-sei=Pan en-aut-mei=Shijun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshidaKeisuke en-aut-sei=Yoshida en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishiyamaSatoshi en-aut-sei=Nishiyama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KojimaTakashi en-aut-sei=Kojima en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HashimotoYutaro en-aut-sei=Hashimoto en-aut-mei=Yutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=TOKEN C.

The species complex is divided into 13 anastomosis groups (AGs) based on hyphal fusion compatibility and further subdivided by culture morphology. While R. solani classifications were shown to be independent of host specificity, it remains unclear whether different R. solani isolates share similar virulence mechanisms. Here, we investigated the infectivity of Japanese R. solani isolates on Brachypodium distachyon and barley. Two isolates, AG-1 IA (from rice) and AG-4 HG-I+II (from cauliflower), infected leaves of both plants, but only AG-4 HG-I+II infected roots. B. distachyon accessions Bd3-1 and Gaz-4 and barley cultivar 'Morex' exhibited enhanced resistance to both isolates compared to B. distachyon Bd21 and barley cultivars 'Haruna Nijo' and 'Golden Promise'. During AG-1 IA infection, but not AG-4 HG-I+II infection, resistant Bd3-1 and Morex induced genes for salicylic acid (SA) and N-hydroxypipecolic acid (NHP) biosynthesis. Pretreatment with SA or NHP conferred resistance to AG-1 IA, but not AG-4 HG-I+II, in susceptible B. distachyon Bd21 and barley Haruna Nijo. On the leaves of susceptible Bd21 and Haruna Nijo, AG-1 IA developed extensive mycelial networks with numerous infection cushions, which are specialized infection structures well-characterized in rice sheath blight. In contrast, AG-4 HG-I+II formed dispersed mycelial masses associated with underlying necrosis. We propose that the R. solani species complex encompasses at least two distinct infection strategies: AG-1 IA exhibits a hemibiotrophic lifestyle, while AG-4 HG-I+II follows a predominantly necrotrophic strategy. en-copyright= kn-copyright= en-aut-name=MahadevanNiranjan en-aut-sei=Mahadevan en-aut-mei=Niranjan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FernandaRozi en-aut-sei=Fernanda en-aut-mei=Rozi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KouzaiYusuke en-aut-sei=Kouzai en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KohnoNatsuka en-aut-sei=Kohno en-aut-mei=Natsuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NagaoReiko en-aut-sei=Nagao en-aut-mei=Reiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NyeinKhin Thida en-aut-sei=Nyein en-aut-mei=Khin Thida kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WatanabeMegumi en-aut-sei=Watanabe en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SakataNanami en-aut-sei=Sakata en-aut-mei=Nanami 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= en-aut-name=ToyodaKazuhiro en-aut-sei=Toyoda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= en-aut-name=MochidaKeiichi en-aut-sei=Mochida en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=HisanoHiroshi en-aut-sei=Hisano en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 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=Crop Stress Management Group, Division of Plant Molecular Regulation Research, Institute of Agrobiological Sciences, National Agriculture and Food Research Organization (NARO) kn-affil= affil-num=4 en-affil=Faculty of Agriculture, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Agriculture, 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= affil-num=10 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=12 en-affil=RIKEN Center for Sustainable Resource Science kn-affil= affil-num=13 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=14 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Rhizoctonia solani species complex kn-keyword=Rhizoctonia solani species complex en-keyword=virulence mechanism kn-keyword=virulence mechanism en-keyword=infection behavior kn-keyword=infection behavior en-keyword=salicylic acid kn-keyword=salicylic acid en-keyword=N-hydroxypipecolic acid kn-keyword=N-hydroxypipecolic acid END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=2 article-no= start-page=108 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250205 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Implementation of Sensor Input Setup Assistance Service Using Generative AI for SEMAR IoT Application Server Platform en-subtitle= kn-subtitle= en-abstract= kn-abstract=For rapid deployments of various IoT application systems, we have developed Smart Environmental Monitoring and Analytical in Real-Time (SEMAR) as an integrated server platform. It is equipped with rich functions for collecting, analyzing, and visualizing various data. Unfortunately, the proper configuration of SEMAR with a variety of IoT devices can be complex and challenging for novice users, since it often requires technical expertise. The assistance of Generative AI can be helpful to solve this drawback. In this paper, we present an implementation of a sensor input setup assistance service for SEMAR using prompt engineering techniques and Generative AI. A user needs to define the requirement specifications and environments of the IoT application system for sensor inputs, and give them to the service. Then, the service provides step-by-step guidance on sensor connections, communicating board configurations, network connections, and communication protocols to the user, which can help the user easily set up the configuration to connect the relevant devices to SEMAR. For evaluations, we applied the proposal to the input sensor setup processes of three practical IoT application systems with SEMAR, namely, a smart light, water heater, and room temperature monitoring system. In addition, we applied it to the setup process of an IoT application system for a course for undergraduate students at the Insitut Bisnis dan Teknologi (INSTIKI), Indonesia. The results demonstrate the effectiveness of the proposed service for SEMAR. en-copyright= kn-copyright= en-aut-name=KotamaI. Nyoman Darma en-aut-sei=Kotama en-aut-mei=I.

We have developed a ready-made server with rich built-in functions to collect, process, display, analyze, and store data from various IoT devices, the SEMAR (Smart Environmental Monitoring and Analytics in Real-Time) IoT application server platform, in which various AI techniques have been implemented to enhance its capabilities. In this paper, we present an application of SEMAR to a drone-based wall inspection system using an object detection AI model called You Only Look Once (YOLO). This system aims to detect wall cracks at high places using images taken via a camera on a flying drone. An edge computing device is installed to control the drone, sending the taken images through the Kafka system, storing them with the drone flight data, and sending the data to SEMAR. The images are analyzed via YOLO through SEMAR. For evaluations, we implemented the system using Ryze Tello for the drone and Raspberry Pi for the edge, and we evaluated the detection accuracy. The preliminary experiment results confirmed the effectiveness of the proposal. en-copyright= kn-copyright= 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=1 ORCID= en-aut-name=HusnaRadhiatul en-aut-sei=Husna en-aut-mei=Radhiatul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NopriantoNobuo en-aut-sei=Noprianto en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=SakamakiShunya en-aut-sei=Sakamaki en-aut-mei=Shunya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SukaridhotoSritrusta en-aut-sei=Sukaridhoto en-aut-mei=Sritrusta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= 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=7 ORCID= en-aut-name=RahmadaniAlfiandi Aulia en-aut-sei=Rahmadani en-aut-mei=Alfiandi Aulia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=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=Department of Informatics and Computer, Politeknik Elektronika Negeri Surabaya kn-affil= affil-num=7 en-affil=Department of Information Technology, State Polytechnic of Malang kn-affil= affil-num=8 en-affil=Department of Electrical Engineering, State Polytechnic of Malang kn-affil= en-keyword=Internet of Things kn-keyword=Internet of Things en-keyword= AI kn-keyword= AI en-keyword= SEMAR kn-keyword= SEMAR en-keyword= crack detection kn-keyword= crack detection en-keyword= drone kn-keyword= drone en-keyword= Kafka kn-keyword= Kafka 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= cd-vols= no-issue= article-no= start-page=e202403213 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250218 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Antifouling Activity of Xylemin, Its Structural Analogs, and Related Polyamines en-subtitle= kn-subtitle= en-abstract= kn-abstract=Biofouling, which is the accumulation of organisms on undersea structures, poses significant global, social, and economic issues. Although organotin compounds were effective antifoulants since the 1960s, they were banned in 2008 due to their toxicity to marine life. Although tin-free alternatives have been developed, they also raise environmental concerns. This underscores the need for effective, nontoxic antifouling agents. We previously synthesized N-(4-aminobutyl)propylamine (xylemin) and its structural analogs. In this study, we assayed the antifouling activity and toxicity of xylemin, its structural analogs, and related polyamines toward cypris larvae of the barnacle Amphibalanus amphitrite. Xylemin and its Boc-protected analog exhibited antifouling activities with 50% effective concentrations (EC50) of 4.25 and 6.11 ?g/mL, respectively. Four xylemin analogs did not show a settlement-inhibitory effect at a concentration of 50 ?g/mL. Putrescine, spermidine, spermine, and thermospermine, which are xylemin-related polyamines, did not display antifoulant effects (EC50 > 50 ?g/mL). All evaluated compounds were nontoxic at a concentration of 50 ?g/mL. These findings indicate that the size and structure of the N-alkyl group are essential for the antifouling activity of xylemin. Therefore, xylemin and its analogs hold promise as nontoxic, eco-friendly antifouling agents, offering a sustainable solution to biofouling in marine environments. en-copyright= kn-copyright= en-aut-name=TakamuraHiroyoshi en-aut-sei=Takamura en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YorisueTakefumi en-aut-sei=Yorisue en-aut-mei=Takefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaKenta en-aut-sei=Tanaka en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KadotaIsao en-aut-sei=Kadota en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Institute of Natural and Environmental Sciences, University of Hyogo kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Amines kn-keyword=Amines en-keyword=Antifouling activity kn-keyword=Antifouling activity en-keyword=Barnacle kn-keyword=Barnacle en-keyword=Structure?activity relationships kn-keyword=Structure?activity relationships en-keyword=Xylemin kn-keyword=Xylemin 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 (PPARƒÁ) 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 ƒÊM) comparable to the synthetic antagonist StemRegenin 1 (SR1) while demonstrating a superior safety profile (median lethal concentration, LC50 > 100 ƒÊM vs. 27.5 ƒÊM 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=64 cd-vols= no-issue=8 article-no= start-page=e202418546 end-page= 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=B,N]Embedded Helical Nanographenes Showing an Ion]Triggered Chiroptical Switching Function en-subtitle= kn-subtitle= en-abstract= kn-abstract=Intramolecular oxidative aromatic coupling of 3,6-bis(m-terphenyl-2f-yl)carbazole provided a bis(m-terphenyl)-fused carbazole, while that of 3,6-bis(m-terphenyl-2f-yl)-1,8-diphenylcarbazole afforded a bis(quaterphenyl)-fused carbazole. Borylation of the latter furnished a B,N-embedded helical nanographene binding a fluoride anion via a structural change from the three-coordinate boron to the four-coordinate boron. The anionic charge derived from the fluoride anion is stabilized over the expanded ƒÎ-framework, which leads to the high binding constant (Ka) of 1~105?M?1. The four-coordinate boron species was converted back to the parent three-coordinate boron species with Ag+, and the chiroptical switch between the three-coordinate boron and four-coordinate boron species has been achieved via the ion recognition with the change in the color and glum values. en-copyright= kn-copyright= en-aut-name=MaedaChihiro en-aut-sei=Maeda en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MichishitaSayaka en-aut-sei=Michishita en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasutomoIssa en-aut-sei=Yasutomo en-aut-mei=Issa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EmaTadashi en-aut-sei=Ema en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Boron kn-keyword=Boron en-keyword=Chirality kn-keyword=Chirality en-keyword=Circularly polarized luminescence kn-keyword=Circularly polarized luminescence en-keyword=Helical nanographenes kn-keyword=Helical nanographenes en-keyword=Ion sensing kn-keyword=Ion sensing END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=1 article-no= start-page=3 end-page=10 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250131 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Investigation of SNPs associated with reproductive and body growth traits in Vietnamese and Nepalese native buffaloes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Water buffaloes are essential to the rural economies of many developing countries, including Vietnam and Nepal, but native buffalo populations in these countries face challenges such as low productivity due to fertility and body growth issues. This study analyzed 34 SNPs in 18 genes associated with reproductive and body growth traits reported in cattle and buffalo in Vietnamese and Nepalese native buffaloes. Results showed no polymorphism at bovine SNPs in either buffalo. Further analysis with SNPs previously reported only in popular buffalo breeds, such as Murrah, found that Vietnamese buffalo were monomorphic at all sites, which may reflect reduced genetic diversity due to population decline. In contrast, Nepalese buffalo, consisting of two native breeds, showed polymorphism in 11 SNPs in 7 genes, with 10 of these matching those found in the Murrah buffalo analyzed here. These findings suggest that these SNPs may be applicable for genetic improvement in Nepalese native buffalo. This study provides valuable insights for future conservation and breeding programs aimed at enhancing reproductive and body growth performance of native buffalo in Vietnam and Nepal. en-copyright= kn-copyright= en-aut-name=Thuy ThanhNguyen en-aut-sei=Thuy Thanh en-aut-mei=Nguyen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuniedaTetsuo en-aut-sei=Kunieda en-aut-mei=Tetsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Manoj KumarShah en-aut-sei=Manoj Kumar en-aut-mei=Shah kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Thu Nu AnhLe en-aut-sei=Thu Nu Anh en-aut-mei=Le kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Van HuuNguyen en-aut-sei=Van Huu en-aut-mei=Nguyen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UshijimaKoichiro en-aut-sei=Ushijima en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NagaeMayuko en-aut-sei=Nagae en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsujiTakehito en-aut-sei=Tsuji en-aut-mei=Takehito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=National Swine Research Program kn-affil= affil-num=4 en-affil=Faculty of Animal Sciences and Veterinary Medicine, University of Agriculture and Forestry, Hue University kn-affil= affil-num=5 en-affil=Faculty of Animal Sciences and Veterinary Medicine, University of Agriculture and Forestry, Hue 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= en-keyword=Vietnamese native buffalo kn-keyword=Vietnamese native buffalo en-keyword=Nepalese native buffalo kn-keyword=Nepalese native buffalo en-keyword=SNPs kn-keyword=SNPs en-keyword=Reproduction kn-keyword=Reproduction en-keyword=Body growth kn-keyword=Body growth END start-ver=1.4 cd-journal=joma no-vol=111 cd-vols= no-issue=6 article-no= start-page=064502 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250204 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Josephson effect and odd-frequency pairing in superconducting junctions with unconventional magnets en-subtitle= kn-subtitle= en-abstract= kn-abstract=We consider Josephson junctions formed by coupling two conventional superconductors via an unconventional magnet and investigate the formation of Andreev bound states, their impact on the Josephson effect, and the emergent superconducting correlations. In particular, we focus on unconventional magnets known as ?-wave altermagnets and ?-wave magnets. We find that the Andreev bound states in ?-wave altermagnet and ??-wave magnet Josephson junctions strongly depend on the transverse momentum, with a spin splitting and low-energy minima as a function of the superconducting phase difference ?. In contrast, the Andreev bound states for ??-wave magnets are insensitive to the transverse momentum. We then show that the Andreev bound states can be probed by the local density of states in the middle of the junction, which also reveals that ??2??2- and ?-wave magnet junctions are prone to host zero energy peaks. While the zero-energy peak in ??2??2-wave altermagnet junctions tends to oscillate with the magnetic order, it remains robust in ?-wave magnet junctions. We then discover that the Josephson current in ?-wave altermagnet junctions is composed of higher harmonics of ?, which originate a ?-Josephson junction behavior entirely controlled by the magnetic order in ????-wave altermagnets. In contrast, the Josephson current in Josephson junctions with ?-wave magnets exhibits a conventional sinelike profile with a fast sign change at ?=? due to zero-energy Andreev bound states. We also demonstrate that the critical currents in ?-wave altermagnet Josephson junctions exhibit an oscillatory decay with the increase of the magnetic order, while the oscillations are absent in ?-wave magnet junctions albeit the currents exhibit a slow decay. Furthermore, we also demonstrate that the interplay of the Josephson effect and unconventional magnetic order of ?-wave altermagnets and ?-wave magnets originates from odd-frequency spin-triplet ?-wave superconducting correlations that are otherwise absent. Our results can serve as a guide to pursue the new functionality of Josephson junctions based on unconventional magnets. en-copyright= kn-copyright= en-aut-name=FukayaYuri en-aut-sei=Fukaya en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaKazuki en-aut-sei=Maeda en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YadaKeiji en-aut-sei=Yada en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=CayaoJorge en-aut-sei=Cayao en-aut-mei=Jorge kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaYukio en-aut-sei=Tanaka en-aut-mei=Yukio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=LuBo en-aut-sei=Lu en-aut-mei=Bo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Faculty of Environmental Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Applied Physics, Nagoya University kn-affil= affil-num=3 en-affil=Department of Applied Physics, Nagoya University kn-affil= affil-num=4 en-affil=Department of Physics and Astronomy, Uppsala University kn-affil= affil-num=5 en-affil=Department of Applied Physics, Nagoya University kn-affil= affil-num=6 en-affil=Center for Joint Quantum Studies, Tianjin Key Laboratory of Low Dimensional Materials Physics and Preparing Technology, Department of Physics, Tianjin University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=2 article-no= start-page=54 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250211 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=White coat color in Vietnamese native buffalo is attributed to the LINE1 insertion in ASIP en-subtitle= kn-subtitle= en-abstract= kn-abstract=The coat color of the swamp buffalo is commonly dark gray, while the white coat color variant, which may have potential heat stress advantages, is also present in some Asian countries, including Vietnam. This study analyzed the most likely candidate genes, ASIP and TYR, responsible for the white coat color of Vietnamese native buffaloes. We found that LINE1 insertion in ASIP, a mutation previously reported in white swamp buffalo from other Asian countries, was exclusively found in white Vietnamese buffalo. Moreover, significantly higher expression of ASIP was confirmed in the hair follicles of white buffalo. On the other hand, no variants associated with the white phenotype were found in TYR. These findings indicate that the LINE1 insertion in ASIP is responsible for the white coat color in Vietnamese native buffalo, and that provides a crucial step towards their utilization and improved productivity in Vietnam. en-copyright= kn-copyright= en-aut-name=NguyenThuy Thanh en-aut-sei=Nguyen en-aut-mei=Thuy Thanh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LeQuan Viet en-aut-sei=Le en-aut-mei=Quan Viet kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NguyenVan Huu en-aut-sei=Nguyen en-aut-mei=Van Huu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DuongHai Thanh en-aut-sei=Duong en-aut-mei=Hai Thanh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsujiTakehito en-aut-sei=Tsuji en-aut-mei=Takehito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Animal Sciences and Veterinary Medicine, University of Agriculture and Forestry, Hue University kn-affil= affil-num=4 en-affil=Faculty of Animal Sciences and Veterinary Medicine, University of Agriculture and Forestry, Hue University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Vietnamese buffalo kn-keyword=Vietnamese buffalo en-keyword=White coat color kn-keyword=White coat color en-keyword=LINE1 insertion kn-keyword=LINE1 insertion en-keyword=ASIP kn-keyword=ASIP END start-ver=1.4 cd-journal=joma no-vol=49 cd-vols= no-issue=4 article-no= start-page=563 end-page=567 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Backside Irradiation of Ultraviolet-A for Correcting Nonuniformity Error of Gafchromic XR-QA2 Films en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: Radiochromic film is used for quality assurance and quality control of X-ray equipment in the diagnostic radiology.

There is a difference in the UV protection strength of radiochromic films. A concern exists about the effects of the UV-A irradiation intensity. We thus irradiated with UV-A rays from the backsides of the films to assess if backside irradiation was possible. Materials and Methods: Gafchromic XR-QA2 and RTQA2 were used in this study. The UV-A rays were simultaneously irradiated on the front and backsides of each film for 12 h. The yellow layer of each film was scanned and imaged. The average pixel values } standard deviations (SDs) were compared. In the statistical analysis, a paired t-test was performed. To compare, the active-layer densities engendered by the UV-A rays. Calibration curve was created with 48 h of preirradiation of UV-A. Results: The mean pixel values } SD for Gafchromic XR-QA2 on the front and backsides were 130.776 } 0.812 and 81.015 } 1.128, respectively. On the other hand, the mean pixel values } SD for Gafchromic RTQA2 on the front and backsides were 62.299 } 1.077 and 133.761 } 1.365, respectively. The statistical results of the paired t-test were significantly different (P < 0.01) between both films. Fitting equation of the calibration curve is shown below. y = -390.47 } 200 + (443.45 } 10x80).5068 } 0.0434. Conclusion: Based on the relationship between the sensitivity of the active layer to UV-A rays and the strength of UV protection on the surface, we concluded that backside irradiation is recommended for Gafchromic XR-QA2, and frontside irradiation is recommended for Gafchromic RTQA2. en-copyright= kn-copyright= en-aut-name=TankiNobuyoshi en-aut-sei=Tanki en-aut-mei=Nobuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GotoSachiko en-aut-sei=Goto en-aut-mei=Sachiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatsudaToshizo en-aut-sei=Katsuda en-aut-mei=Toshizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GotandaRumi en-aut-sei=Gotanda en-aut-mei=Rumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=GotandaTatsuhiro en-aut-sei=Gotanda en-aut-mei=Tatsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KuwanoTadao en-aut-sei=Kuwano en-aut-mei=Tadao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Medical Radiation Technology, Shizuoka College of Medicalcare Science kn-affil= affil-num=4 en-affil=Department of Radiological Technology, Faculty of Health Science and Technology, Kawasaki University of Medical Welfare kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Faculty of Health Science and Technology, Kawasaki University of Medical Welfare kn-affil= affil-num=6 en-affil=Department of Radiology, Osaka Center for Cancer and Cardiovascular Diseases Prevention kn-affil= en-keyword=Backside irradiation kn-keyword=Backside irradiation en-keyword=computed tomography kn-keyword=computed tomography en-keyword=reflective type radiochromic film kn-keyword=reflective type radiochromic film en-keyword=ultraviolet radiation kn-keyword=ultraviolet radiation 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?

Immunohistochemical analysis of human normal articular cartilage and cartilage tissues from patients with osteoarthritis (OA) obtained during surgery of the knee joint showed marked LRP4 expression in the early stages of OA, which then decreased with cartilage degeneration, whereas Agrin was consistently increased with cartilage degeneration. In normal human articular chondrocytes (NHACs), mild cyclic tensile strain (CTS) (0.5 Hz, 5% elongation, 2 h) increased the expression of LRP4 and aggrecan (ACAN), while intense CTS (0.5 Hz, 10% elongation, 6 h) increased the expression of Agrin without affecting LRP4 expression. Treatment with recombinant human (rh) Agrin downregulated the mRNA expression of LRP4 and ACAN, but upregulated the expression of LRP5/6, SRY-box transcription factor 9 (SOX9), Runt-related transcription factor 2 (RUNX2), and a disintegrin and metalloproteinase with thrombospondin motifs-4 (ADAMTS-4). Immunocytochemistry and Western blot analysis showed that rhAgrin treatment upregulated the expression of ƒÀ-catenin and SOX9. Agrin knockdown by siAGRN transfection partially reduced the nuclear protein expression of ƒÀ-catenin, which was increased with intense CTS. LRP4 knockdown by siLRP4 transfection increased the expression of LRP5/6, SOX9, RUNX2, ADAMTS-4, and Agrin. These results suggested that intense CTS increases the expression of Agrin, which might interfere with the role of LRP4 in the inhibition of LRP5/6 and their downstream ƒÀ-catenin signaling, leading to cartilage degeneration. en-copyright= kn-copyright= en-aut-name=NaniwaShuichi en-aut-sei=Naniwa en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishidaKeiichiro en-aut-sei=Nishida en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshidaAki en-aut-sei=Yoshida en-aut-mei=Aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NasuYoshihisa en-aut-sei=Nasu en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakaharaRyuichi en-aut-sei=Nakahara en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhtsukiTakashi en-aut-sei=Ohtsuki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HottaYoshifumi en-aut-sei=Hotta en-aut-mei=Yoshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShimizuNoriyuki en-aut-sei=Shimizu en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IchikawaChinatsu en-aut-sei=Ichikawa en-aut-mei=Chinatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=LinDeting en-aut-sei=Lin en-aut-mei=Deting kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OtsukaNoriaki en-aut-sei=Otsuka en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Section of Medicine, Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=2 en-affil=Locomotive Pain Center, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Section of Medicine, Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=4 en-affil=Locomotive Pain Center, Okayama University Hospital kn-affil= affil-num=5 en-affil=Locomotive Pain Center, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Sayo Central Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Section of Medicine, Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Section of Medicine, Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Section of Medicine, Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=11 en-affil=Department of Orthopaedic Surgery, Section of Medicine, Division of Medicine, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=12 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=osteoarthritis kn-keyword=osteoarthritis en-keyword=chondrocyte kn-keyword=chondrocyte en-keyword=mechanical stress kn-keyword=mechanical stress en-keyword=LRP4 kn-keyword=LRP4 en-keyword=Agrin kn-keyword=Agrin en-keyword=ƒÀ-catenin kn-keyword=ƒÀ-catenin en-keyword=SOX9 kn-keyword=SOX9 END start-ver=1.4 cd-journal=joma no-vol=60 cd-vols= no-issue=1 article-no= start-page=vvae044 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=The effects of soybeans and its derivatives on oral diseases: a narrative review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Soybean is a widely utilized protein source that originated in China and has been associated with preventing and treating various diseases.

The fly can pollinate at lower and higher temperatures than European honeybee. However, management of the longevity of pollinators is important for growers using greenhouses. Previous studies using other insects showed that caffeine affects insect longevity and behaviors. For instance, European honeybee live longer and have increased memory after caffeine consumption. How caffeine affects the longevity and behavior of pollinators is worth investigating because it can affect pollinatorfs behavior, extend longevity, or be an insecticide against pollinators. In the present study, therefore, the longevity and locomotion of L. sericata were investigated when they were given different caffeine concentrations. First, the longevity of L. sericata with five different caffeine concentrations was compared to the control. The results showed that higher concentrations of caffeine (2%, 1%, and 0.5%) significantly decreased the life span compared to lower concentrations (0.05% and 0.01%). Second, the locomotion activities of L. sericata were examined at those two caffeine concentrations with treated and control male and female flies utilizing a Drosophila Activity Monitor (DAM). Treatment with 0.05% caffeine dramatically reduced locomotion, but treatment of 0.01% caffeine did not. We also compared lipid concentrations of flies: flies treated with 0.05% caffeine had a lower lipid concentration compared to flies treated with 0% and 0.01% caffeine. These results indicate that caffeine had negative effects on the longevity and locomotion activities of the pollinator L. sericata in laboratory conditions. en-copyright= kn-copyright= en-aut-name=NaingShine Shane en-aut-sei=Naing en-aut-mei=Shine Shane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiokaHaruna en-aut-sei=Fujioka en-aut-mei=Haruna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuuraTeruhisa en-aut-sei=Matsuura en-aut-mei=Teruhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Caffeine kn-keyword=Caffeine en-keyword=Life span kn-keyword=Life span en-keyword=Locomotor activity kn-keyword=Locomotor activity en-keyword=Pollinator kn-keyword=Pollinator 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=61 cd-vols= no-issue=24 article-no= start-page=4606 end-page=4620 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=Nano/microparticle-based tough and recyclable polymers toward a sustainable society en-subtitle= kn-subtitle= en-abstract= kn-abstract=By virtue of their unique properties, polymer nano/microparticles constitute important building blocks for the construction of functional nanomaterials. Although intense research efforts in this field have laid the foundation for the applications of polymer nano/microparticle-based latex films, cutting-edge innovations in the recycling of polymer materials are still required for the realization of a sustainable society. This feature article reviews our recent attempts to develop the applications of polymer nano/microparticles in the context of a circular society on the basis of the precise synthesis of single nano/microparticles and multiscale structural analysis. en-copyright= kn-copyright= en-aut-name=SasakiYuma en-aut-sei=Sasaki en-aut-mei=Yuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishizawaYuichiro en-aut-sei=Nishizawa en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurehaTakuma en-aut-sei=Kureha en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuzukiDaisuke en-aut-sei=Suzuki en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Frontier Materials Chemistry, Graduate School of Science and Technology, Hirosaki University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=1 article-no= start-page=21 end-page=30 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=Prediction of Prostate Cancer Grades Using Radiomic Features en-subtitle= kn-subtitle= en-abstract= kn-abstract=We developed a machine learning model for predicting prostate cancer (PCa) grades using radiomic features of magnetic resonance imaging. 112 patients diagnosed with PCa based on prostate biopsy between January 2014 and December 2021 were evaluated. Logistic regression was used to construct two prediction models, one using radiomic features and prostate-specific antigen (PSA) values (Radiomics model) and the other Prostate Imaging-Reporting and Data System (PI-RADS) scores and PSA values (PI-RADS model), to differentiate high-grade (Gleason score [GS] ? 8) from intermediate or low-grade (GS < 8) PCa. Five imaging features were selected for the Radiomics model using the Gini coefficient. Model performance was evaluated using AUC, sensitivity, and specificity. The models were compared by leave-one-out cross-validation with Ridge regularization. Furthermore, the Radiomics model was evaluated using the holdout method and represented by a nomogram. The AUC of the Radiomics and PI-RADS models differed significantly (0.799, 95% CI: 0.712-0.869; and 0.710, 95% CI: 0.617-0.792, respectively). Using holdout method, the Radiomics model yielded AUC of 0.778 (95% CI: 0.552-0.925), sensitivity of 0.769, and specificity of 0.778. It outperformed the PI-RADS model and could be useful in predicting PCa grades, potentially aiding in determining appropriate treatment approaches in PCa patients. en-copyright= kn-copyright= en-aut-name=YamamotoYasuhiro en-aut-sei=Yamamoto en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HaraguchiTakafumi en-aut-sei=Haraguchi en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsudaKaori en-aut-sei=Matsuda en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkazakiYoshio en-aut-sei=Okazaki en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimotoShin en-aut-sei=Kimoto en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanjiNozomu en-aut-sei=Tanji en-aut-mei=Nozomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoAtsushi en-aut-sei=Matsumoto en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KobayashiYasuyuki en-aut-sei=Kobayashi en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MimuraHidefumi en-aut-sei=Mimura en-aut-mei=Hidefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Radiology, Houshasen Daiichi Hospital kn-affil= affil-num=2 en-affil=Department of Advanced Biomedical Imaging and Informatics, St. Marianna University School of Medicine kn-affil= affil-num=3 en-affil=Department of Radiology, Houshasen Daiichi Hospital kn-affil= affil-num=4 en-affil=Department of Radiology, Houshasen Daiichi Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Houshasen Daiichi Hospital kn-affil= affil-num=6 en-affil=Department of Urology, Houshasen Daiichi Hospital kn-affil= affil-num=7 en-affil=Department of Urology, Houshasen Daiichi Hospital kn-affil= affil-num=8 en-affil=Department of Medical Information and Communication Technology Research, St. Marianna University School of Medicine kn-affil= affil-num=9 en-affil=Department of Radiology, St. Marianna University School of Medicine kn-affil= affil-num=10 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=prostate cancer kn-keyword=prostate cancer en-keyword=machine learning kn-keyword=machine learning en-keyword=prostate Imaging-Reporting and Data System kn-keyword=prostate Imaging-Reporting and Data System en-keyword=radiomics kn-keyword=radiomics en-keyword=Gleason score kn-keyword=Gleason score END start-ver=1.4 cd-journal=joma no-vol=121 cd-vols= no-issue=35 article-no= start-page=e2320189121 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240821 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Somatic mutations in tumor-infiltrating lymphocytes impact on antitumor immunity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immune checkpoint inhibitors (ICIs) exert clinical efficacy against various types of cancers by reinvigorating exhausted CD8+ T cells that can expand and directly attack cancer cells (cancer-specific T cells) among tumor-infiltrating lymphocytes (TILs). Although some reports have identified somatic mutations in TILs, their effect on antitumor immunity remains unclear. In this study, we successfully established 18 cancer-specific T cell clones, which have an exhaustion phenotype, from the TILs of four patients with melanoma. We conducted whole-genome sequencing for these T cell clones and identified various somatic mutations in them with high clonality. Among the somatic mutations, an SH2D2A loss-of-function frameshift mutation and TNFAIP3 deletion could activate T cell effector functions in vitro. Furthermore, we generated CD8+ T cell?specific Tnfaip3 knockout mice and showed that Tnfaip3 function loss in CD8+ T cell increased antitumor immunity, leading to remarkable response to PD-1 blockade in vivo. In addition, we analyzed bulk CD3+ T cells from TILs in additional 12 patients and identified an SH2D2A mutation in one patient through amplicon sequencing. These findings suggest that somatic mutations in TILs can affect antitumor immunity and suggest unique biomarkers and therapeutic targets. en-copyright= kn-copyright= en-aut-name=MukoharaFumiaki

analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, it was conducted to observe the propagation behavior of small fatigue cracks generated on the surface of ƒ¿-brass and pure copper, using an electrodynamic plane bending fatigue testing machine. The EBSD method was also used to analyze the crystal orientation near the bottom of the notch on the surface of the test piece. For each slip system of the grain, we calculated the slip factor, defined as the ratio of resolved shear stresses that considers the singular stress field at the crack tip, and investigated the relationship between the propagation behavior of small cracks and the slip factor. Furthermore, we performed a crystal plasticity finite element analysis (CP-FEM) using a crystal plasticity FEM model created from the grains obtained by the EBSD method to predict the deflection behavior of small fatigue cracks when propagating through the grain boundaries. The results indicated that when a crack propagates across a grain boundary, it is difficult to predict the deflection behavior using slip factors, however, the deflection behavior of a crack can be predicted from the resolved shear stress calculated using CP-FEM, which considers the mechanical interactions between crystal grains. en-copyright= kn-copyright= en-aut-name=ArakawaJinta en-aut-sei=Arakawa en-aut-mei=Jinta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YabukiRyo en-aut-sei=Yabuki en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UemoriTakeshi en-aut-sei=Uemori en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ItoMasato en-aut-sei=Ito en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YaguchiKenichi en-aut-sei=Yaguchi en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Innovation Center, Mitsubishi Materials Corporation kn-affil= affil-num=5 en-affil=Innovation Center, Mitsubishi Materials Corporation kn-affil= en-keyword=Small fatigue crack kn-keyword=Small fatigue crack en-keyword=Crystal orientation kn-keyword=Crystal orientation en-keyword=CP-FEM kn-keyword=CP-FEM en-keyword=EBSD kn-keyword=EBSD END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=RP99858 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241031 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structural basis for molecular assembly of fucoxanthin chlorophyll a/c-binding proteins in a diatom photosystem I supercomplex en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photosynthetic organisms exhibit remarkable diversity in their light-harvesting complexes (LHCs). LHCs are associated with photosystem I (PSI), forming a PSI-LHCI supercomplex. The number of LHCI subunits, along with their protein sequences and pigment compositions, has been found to differ greatly among the PSI-LHCI structures. However, the mechanisms by which LHCIs recognize their specific binding sites within the PSI core remain unclear. In this study, we determined the cryo-electron microscopy structure of a PSI supercomplex incorporating fucoxanthin chlorophyll a/c-binding proteins (FCPs), designated as PSI-FCPI, isolated from the diatom Thalassiosira pseudonana CCMP1335. Structural analysis of PSI-FCPI revealed five FCPI subunits associated with a PSI monomer; these subunits were identified as RedCAP, Lhcr3, Lhcq10, Lhcf10, and Lhcq8. Through structural and sequence analyses, we identified specific protein-protein interactions at the interfaces between FCPI and PSI subunits, as well as among FCPI subunits themselves. Comparative structural analyses of PSI-FCPI supercomplexes, combined with phylogenetic analysis of FCPs from T. pseudonana and the diatom Chaetoceros gracilis, underscore the evolutionary conservation of protein motifs crucial for the selective binding of individual FCPI subunits. These findings provide significant insights into the molecular mechanisms underlying the assembly and selective binding of FCPIs in diatoms. en-copyright= kn-copyright= en-aut-name=KatoKoji en-aut-sei=Kato en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakajimaYoshiki en-aut-sei=Nakajima en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=XingJian en-aut-sei=Xing en-aut-mei=Jian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KumazawaMinoru en-aut-sei=Kumazawa en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OgawaHaruya en-aut-sei=Ogawa en-aut-mei=Haruya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShenJian-Ren en-aut-sei=Shen en-aut-mei=Jian-Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IfukuKentaro en-aut-sei=Ifuku en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NagaoRyo en-aut-sei=Nagao en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=4 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science and Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=8 en-affil=Faculty of Agriculture, Shizuoka University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=114 cd-vols= no-issue= article-no= start-page=11 end-page=20 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Uncovering the role of arcuate kisspeptin neurons as a source of the gonadotropin-releasing hormone pulse generator using gene-modified rats kn-title=ˆâ“`Žq‰ü•Ïƒ‰ƒbƒg‚ð—p‚¢‚½‹|óŠjƒLƒXƒyƒvƒ`ƒ“ƒjƒ…[ƒƒ“‚Ì«‘BŽhŒƒƒzƒ‹ƒ‚ƒ“•úoƒzƒ‹ƒ‚ƒ“ƒpƒ‹ƒXƒWƒFƒlƒŒ[ƒ^[‚Æ‚µ‚Ä‚Ì–ðŠ„‰ð–¾ en-subtitle= kn-subtitle= en-abstract=@¢ŠE‚É‚¨‚¢‚ÄC“û‹‚ÌŽó‘Ù—¦i”DP—¦j‚ª’ቺ‚µ‚Ä‚¨‚èC‰Æ’{‚Ì”ÉB¬ÑŒüã‚Ì‚½‚ß‚ÌŒø‰Ê“I‚ÈŽ¡—Ö@‚ª•K—v‚Æ‚³‚ê‚Ä‚¢‚éD‰Æ’{‚ðŠÜ‚ÞšM“û—Þ‚É‚¨‚¢‚ÄC¶B‹@”\‚ÍŽ‹°‰º•”|‰º‚‘Ì|«‘BŽ²‚©‚番”傳‚ê‚éƒzƒ‹ƒ‚ƒ“‚É‚æ‚Á‚ħŒä‚³‚ê‚Ä‚¢‚éD‚±‚ê‚ç‚̃zƒ‹ƒ‚ƒ“‚Ì‚¤‚¿C«‘BŽhŒƒƒzƒ‹ƒ‚ƒ“•úoƒzƒ‹ƒ‚ƒ“iGnRHj‚̃pƒ‹ƒX󕪔åiGnRH ƒpƒ‹ƒXj‚ÍC«‘BŽhŒƒƒzƒ‹ƒ‚ƒ“•ª”å‚Æ«‘B‹@”\‚É–{Ž¿“I‚Éd—v‚Å‚ ‚éD‚µ‚½‚ª‚Á‚ÄCGnRH ƒpƒ‹ƒX‚ð§Œä‚·‚郃JƒjƒYƒ€iGnRH ƒpƒ‹ƒXƒWƒFƒlƒŒ[ƒ^[j‚ð‰ð–¾‚·‚邱‚Æ‚ÍC‰Æ’{‚̶B‹Zp‚ðŒüコ‚¹‚邽‚ß‚É•s‰ÂŒ‡‚Å‚ ‚éD–{‘à‚Å‚ÍC’˜ŽÒ‚ç‚̈â“`Žq‰ü•Ïƒ‰ƒbƒgƒ‚ƒfƒ‹‚ð—p‚¢‚½‹|óŠjƒLƒXƒyƒvƒ`ƒ“ƒjƒ…[ƒƒ“iƒ¨NDy ƒjƒ…[ƒƒ“‚Æ‚µ‚Ä‚à’m‚ç‚ê‚éj‚ªGnRH ƒpƒ‹ƒXƒWƒFƒlƒŒ[ƒ^[‚Ì–{‘Ì‚Å‚ ‚邱‚Æ‚Ì’¼Ú“I‚ÈØ‹’‚ðŽ¦‚µ‚½Œ¤‹†‚ð’†S‚Æ‚µ‚ÄC‰ß‹Ž20”NŠÔ‚ÌŒ¤‹†‚ðŠTà‚µ‚½D‚Ü‚½Cƒ¨NDy ƒjƒ…[ƒƒ“‚ª•ª”å‚·‚éƒjƒ…[ƒƒLƒjƒ“BCƒOƒ‹ƒ^ƒ~ƒ“Ž_Cƒ_ƒCƒmƒ‹ƒtƒBƒ“A ‚ªƒ¨NDy ƒjƒ…[ƒƒ“‚Ì_ŒoŠˆ“®‚𓯊ú‚³‚¹CGnRH ƒpƒ‹ƒX‚ð”­¶‚³‚¹‚郃JƒjƒYƒ€‚ɂ‚¢‚Ę_‚¶‚½Dˆâ“`Žq‰ü•Ïƒ‰ƒbƒgƒ‚ƒfƒ‹‚©‚瓾‚ç‚ꂽ’mŽ¯‚ÍCGnRH/ «‘BŽhŒƒƒzƒ‹ƒ‚ƒ“ƒpƒ‹ƒX‚ðŽhŒƒ‚µ‚ÄC‰Æ’{‚Ì”ÉB”\—Í‚ðŒüコ‚¹‚éV‹K”ÉB‘£iÜŠJ”­‚ÉŠñ—^‚·‚é‚ÆŠú‘Ò‚Å‚«‚éD kn-abstract=@Strategies for increasing reproductive performance are needed for domestic animals because for example the conception (pregnancy) rate has decreased in dairy cows around the world. Reproductive function is controlled by hormones released by the hypothalamus-pituitary-gonadal axis in mammals, including domestic animals. Of those hormones, tonic (pulsatile) gonadotropin-releasing hormone (GnRH) release is fundamentally important for gonadotropin release and gonadal activity. Therefore, uncovering the mechanism controlling GnRH pulses, that is GnRH pulse generator, is essential to improve reproductive technologies for domestic animals. The present review is focused on the indispensable role of arcuate nucleus (ARC) kisspeptin neurons (also known as KNDy neurons) as the GnRH pulse generator in mammals. First, we give a brief overview of studies on hypothalamic kisspeptin neurons throughout the past two decades. Second, we review studies that have provided direct evidence that ARC kisspeptin neurons serve as the GnRH pulse generator, with a special focus on our gene-modified rat models. Finally, we discuss the mechanism underlying GnRH pulse generation. The knowledge obtained from gene-modified rat models should be clinically important and could be adapted to new tools to improve reproductive performance in livestock by stimulating GnRH/gonadotropin pulses. en-copyright= kn-copyright= en-aut-name=NagaeMayuko en-aut-sei=Nagae en-aut-mei=Mayuko kn-aut-name=’·]–ƒ—CŽq kn-aut-sei=’·] kn-aut-mei=–ƒ—CŽq aut-affil-num=1 ORCID= en-aut-name=UenoyamaYoshihisa en-aut-sei=Uenoyama en-aut-mei=Yoshihisa kn-aut-name=ã–ìŽR‰ê‹v kn-aut-sei=ã–ìŽR kn-aut-mei=‰ê‹v aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=‰ªŽR‘åŠw‘åŠw‰@ŠÂ‹«¶–½Ž©‘R‰ÈŠwŒ¤‹†‰È affil-num=2 en-affil=Graduate School of Bioagricultural Sciences, Nagoya University kn-affil=–¼ŒÃ‰®‘åŠw‘åŠw‰@¶–½”_ŠwŒ¤‹†‰È en-keyword=gene-modified rats kn-keyword=gene-modified rats en-keyword=GnRH kn-keyword=GnRH en-keyword=kisspeptin kn-keyword=kisspeptin en-keyword=LH kn-keyword=LH en-keyword=pulse generator kn-keyword=pulse generator END start-ver=1.4 cd-journal=joma no-vol=114 cd-vols= no-issue= article-no= start-page=1 end-page=10 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of dark respiration on dry matter production of various crop species en-subtitle= kn-subtitle= en-abstract= kn-abstract=@Eleven crops were cultivated: maize, sunflower, soybean, groundnuts, sesame, kenaf, barley, wheat, rice, potato, and sweet potato. The crop growth rate (CGR) and specific dark-respiration rate (Rs) were measured, and growth efficiency GE =CGR/(CGR+R) (R, respiratory loss) was calculated. In each crop, whole-plant Rs reached a maximum in the earlier stages of growth, declined rapidly until the early reproductive growth, and remained almost constant during the ripening period. The Rs of leaves was higher than that of stems during the reproductive growth period, except for maize and potato. The Rs of storage organs was highest in the earlier stages, followed by a rapid decline to similar or lower values than those of leaves and stems during the ripening period. The GE in whole plant was higher than 60% in wheat, maize, barley, sunflower, rice, kenaf, sesame, but lower in soybean, sweet potato and groundnuts, and lowest in potato, which was affected by the higher respiratory loss. The GE in whole plant during the reproductive growth period was significantly lower, which we attributed to increased maintenance costs due to the increase of non-assimilative organs, and decrease in the dry weight of vegetative organs. A positive correlation was observed between the carbohydrate content of storage organs and GE, indicating that a crop with higher carbohydrate content in storage organs tended to have a higher GE. Crops with higher protein and crude fat content in storage organs tended to have lower GE. The GE over the growing season was low for kenaf, a fiber crop which contains high molecular weight compounds such as lignin and cellulose, and lower for sesame, groundnuts, and soybean, which contain high oil and protein and have high respiration costs for the synthesis of storage materials, suggesting that these higher respiration costs are related to lower dry matter production and hence lower yields. en-copyright= kn-copyright= en-aut-name=SaitohKuniyuki en-aut-sei=Saitoh en-aut-mei=Kuniyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MurakamiTomohiro en-aut-sei=Murakami en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraYumi en-aut-sei=Nakamura en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishiboriMisa en-aut-sei=Nishibori en-aut-mei=Misa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakagoshiYuki en-aut-sei=Takagoshi en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HiraiYoshihiko en-aut-sei=Hirai en-aut-mei=Yoshihiko 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 Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=School of Agriculture, Okayama University kn-affil= affil-num=4 en-affil=School of Agriculture, 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= en-keyword=Cereal crops kn-keyword=Cereal crops en-keyword=Oil crops kn-keyword=Oil crops en-keyword=Crop growth rate kn-keyword=Crop growth rate en-keyword=Dark-respiration kn-keyword=Dark-respiration en-keyword=Growth efficiency kn-keyword=Growth efficiency en-keyword=Leguminous crops kn-keyword=Leguminous crops en-keyword=Nutrients composition kn-keyword=Nutrients composition en-keyword=Respiratory loss kn-keyword=Respiratory loss en-keyword=Root and tuber crops kn-keyword=Root and tuber crops END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=63 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250113 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Impact of Task Context on Pleasantness and Softness Estimations: A Study Based on Three Touch Strategies en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study investigated the two distinct perceptions (pleasantness and softness) of deformable stimuli with different degrees of compliance under conditions with and without a contextual task. Three tactile strategies-grasping, pinching, and pressing-were used to perceive the stimuli. In Experiment 1 (without a contextual task), participants estimated the perceived intensity of softness or pleasantness for each stimulus. In Experiment 2 (with a contextual task), the participants sequentially perceived two stimuli with different compliance levels and indicated which stimulus they perceived as softer and pleasant. The results showed that the psychophysical relationship between compliance and perceived softness was consistent across all tactile strategies in both experiments, with softness estimates increasing as compliance increased. However, the relationship between compliance and pleasantness differed between the two experiments. In Experiment 1, pleasantness estimates increased monotonically with increased compliance. However, in Experiment 2, across all tactile strategies, pleasantness began to decrease within the compliance range of 0.25-2.0 cm2/N, exhibiting an inverted U-shaped trend. These findings indicate that the relationship between compliance and pleasantness is task-dependent, particularly demonstrating significantly different trends when a contextual task is introduced. In contrast, the relationship between compliance and softness remained consistently monotonic. en-copyright= kn-copyright= en-aut-name=GaoBinyue en-aut-sei=Gao en-aut-mei=Binyue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YuYinghua en-aut-sei=Yu en-aut-mei=Yinghua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EjimaYoshimichi en-aut-sei=Ejima en-aut-mei=Yoshimichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WuJinglong en-aut-sei=Wu en-aut-mei=Jinglong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YangJiajia en-aut-sei=Yang en-aut-mei=Jiajia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=pleasantness kn-keyword=pleasantness en-keyword=softness kn-keyword=softness en-keyword=touch strategy kn-keyword=touch strategy en-keyword=task context kn-keyword=task context en-keyword=psychophysics kn-keyword=psychophysics 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. A reported discrepancy in neutron detection efficiency between observational data and simulation predictions prompted an investigation into neutron capture modeling in Geant4. The study revealed that an overestimation of the thermal motion of hydrogen atoms in Geant4 impacts the fraction of captured nuclei. 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=14 cd-vols= no-issue=1 article-no= start-page=25 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250115 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Investigation of Hand Gestures for Controlling Video Games in a Rehabilitation Exergame System en-subtitle= kn-subtitle= en-abstract= kn-abstract=Musculoskeletal disorders (MSDs) can significantly impact individuals' quality of life (QoL), often requiring effective rehabilitation strategies to promote recovery. However, traditional rehabilitation methods can be expensive and may lack engagement, leading to poor adherence to therapy exercise routines. An exergame system can be a solution to this problem. In this paper, we investigate appropriate hand gestures for controlling video games in a rehabilitation exergame system. The Mediapipe Python library is adopted for the real-time recognition of gestures. We choose 10 easy gestures among 32 possible simple gestures. Then, we specify and compare the best and the second-best groups used to control the game. Comprehensive experiments are conducted with 16 students at Andalas University, Indonesia, to find appropriate gestures and evaluate user experiences of the system using the System Usability Scale (SUS) and User Experience Questionnaire (UEQ). The results show that the hand gestures in the best group are more accessible than in the second-best group. The results suggest appropriate hand gestures for game controls and confirm the proposal's validity. In future work, we plan to enhance the exergame system by integrating a diverse set of video games, while expanding its application to a broader and more diverse sample. We will also study other practical applications of the hand gesture control function. en-copyright= kn-copyright= en-aut-name=HusnaRadhiatul en-aut-sei=Husna en-aut-mei=Radhiatul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BrataKomang Candra en-aut-sei=Brata en-aut-mei=Komang Candra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AnggrainiIrin Tri en-aut-sei=Anggraini en-aut-mei=Irin Tri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=RahmadaniAlfiandi Aulia en-aut-sei=Rahmadani en-aut-mei=Alfiandi Aulia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FanChih-Peng en-aut-sei=Fan en-aut-mei=Chih-Peng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Electrical Engineering, State Polytechnic of Malang kn-affil= affil-num=6 en-affil=Department of Electrical Engineering, National Chung Hsing University kn-affil= en-keyword=hand gesture kn-keyword=hand gesture en-keyword=application control kn-keyword=application control en-keyword=exergame kn-keyword=exergame en-keyword=SUS kn-keyword=SUS en-keyword=UEQ kn-keyword=UEQ en-keyword=python kn-keyword=python en-keyword=mediapipe kn-keyword=mediapipe 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 patientsf 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 patientsf 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=

Proposal of In Situ Authoring Tool with Visual-Inertial Sensor Fusion for Outdoor Location-Based Augmented Reality en-subtitle= kn-subtitle= en-abstract= kn-abstract=In location-based augmented reality (LAR) applications, a simple and effective authoring tool is essential to create immersive AR experiences in real-world contexts. Unfortunately, most of the current tools are primarily desktop-based, requiring manual location acquisitions, the use of software development kits (SDKs), and high programming skills, which poses significant challenges for novice developers and a lack of precise LAR content alignment. In this paper, we propose an intuitive in situ authoring tool with visual-inertial sensor fusions to simplify the LAR content creation and storing process directly using a smartphone at the point of interest (POI) location. The tool localizes the userfs position using smartphone sensors and maps it with the captured smartphone movement and the surrounding environment data in real-time. Thus, the AR developer can place a virtual object on-site intuitively without complex programming. By leveraging the combined capabilities of Visual Simultaneous Localization and Mapping(VSLAM) and Google Street View (GSV), it enhances localization and mapping accuracy during AR object creation. For evaluations, we conducted extensive user testing with 15 participants, assessing the task success rate and completion time of the tool in practical pedestrian navigation scenarios. The Handheld Augmented Reality Usability Scale (HARUS) was used to evaluate overall user satisfaction. The results showed that all the participants successfully completed the tasks, taking 16.76 s on average to create one AR object in a 50 m radius area, while common desktop-based methods in the literature need 1?8 min on average, depending on the userfs expertise. Usability scores reached 89.44 for manipulability and 85.14 for comprehensibility, demonstrating the high effectiveness in simplifying the outdoor LAR content creation process. en-copyright= kn-copyright= en-aut-name=BrataKomang Candra en-aut-sei=Brata en-aut-mei=Komang Candra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=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=3 ORCID= en-aut-name=MentariMustika en-aut-sei=Mentari en-aut-mei=Mustika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=RahmadaniAlfiandi Aulia en-aut-sei=Rahmadani en-aut-mei=Alfiandi Aulia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil= Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil= Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil= Department of Information and Communication Systems, Okayama University kn-affil= affil-num=4 en-affil= Department of Information and Communication Systems, Okayama University kn-affil= affil-num=5 en-affil= Department of Information Technology, Politeknik Negeri Malang kn-affil= affil-num=6 en-affil= Department of Information Technology, Politeknik Negeri Malang kn-affil= en-keyword=location-based augmented reality (LAR) kn-keyword=location-based augmented reality (LAR) en-keyword=authoring tool kn-keyword=authoring tool en-keyword=outdoor kn-keyword=outdoor en-keyword=VSLAM kn-keyword=VSLAM en-keyword=Google Street View (GSV) kn-keyword=Google Street View (GSV) en-keyword=handheld augmented reality usability scale (HARUS) kn-keyword=handheld augmented reality usability scale (HARUS) END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=1 article-no= start-page=65 end-page=69 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=Effectiveness of sensing gloves?applied virtual reality education system on hand hygiene practice: A randomized controlled trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: 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=234 cd-vols= no-issue= article-no= start-page=120015 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250305 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reversible chemical modifications of graphene oxide for enhanced viral capture and release in water en-subtitle= kn-subtitle= en-abstract= kn-abstract=Detecting low concentrations of viruses in sewage water is crucial for monitoring the spread of emerging viral diseases. However, current detection methods, which involve concentrating viruses using traditional materials such as gauze or cotton, have limitations in effectively accomplishing this task. This study demonstrates that graphene oxide (GO), a two-dimensional carbon material, possesses strong viral adsorption capabilities. However, it lacks efficiency for effective viral release. Therefore, we designed a series of new GO-based materials, which exhibited a viral adsorption similar to pristine GO, while significantly enhancing their release performance by attaching alkyl chains and hydrophilic functional groups. Among the synthesized materials, 1,8-aminooctanol grafted to GO (GO-NH2C8OH) has emerged as the most promising candidate, achieving a viral release rate higher than 50 %. This superior performance can be attributed to the synergistic effect of the alkyl chain and the terminal OH group, which enhances both its affinity for viruses and water dispersibility. Furthermore, we have successfully applied GO-NH2C8OH in a new protocol for concentrating viruses from sewage wastewater. This approach has demonstrated a 200-fold increase in virus concentration, allowing PCR detection of this type of pathogens present in wastewater below the detection limit by direct analysis, underscoring its significant potential for virus surveillance. en-copyright= kn-copyright= en-aut-name=Ferr?-PujolPilar en-aut-sei=Ferr?-Pujol en-aut-mei=Pilar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ObataSeiji en-aut-sei=Obata en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=RayaJ?sus en-aut-sei=Raya en-aut-mei=J?sus kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BiancoAlberto en-aut-sei=Bianco en-aut-mei=Alberto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatayamaHiroyuki en-aut-sei=Katayama en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatoTakashi en-aut-sei=Kato en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= 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=Institut de Chimie, UMR 7177 CNRS, Universit? de Strasbourg kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Urban Engineering, School of Engineering, The University of Tokyo kn-affil= affil-num=6 en-affil=Research Center for Water Environment Technology, School of Engineering, The University of Tokyo kn-affil= affil-num=7 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=Carbon nanomaterials kn-keyword=Carbon nanomaterials en-keyword=Functionalization kn-keyword=Functionalization en-keyword=Adsorption kn-keyword=Adsorption en-keyword=Desorption kn-keyword=Desorption en-keyword=Pathogens kn-keyword=Pathogens 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 villagersf 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 villagersf 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=41 cd-vols= no-issue=4 article-no= start-page=2679 end-page=2687 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Formation of Nanowindow between Graphene Oxide and Carbon Nanohorn Assisted by Metal Ions en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study presents a novel nanostructured material formed by inserting oxidized carbon nanohorns (CNHox) between layered graphene oxide (GO) nanosheets using metal ions (M) from nitrate as intermediates. The resulting GO?CNHox-M structure effectively mitigated interlayer aggregation of the GO nanosheets. This insertion strategy promoted the formation of nanowindows on the surface of the GO sheets and larger mesopores between the GO nanosheets, improving material porosity. Characterization revealed successful CNHox insertion, which increased interlayer spacing and reduced GO stacking. The GO?CNHox-Ca exhibited a significantly higher specific surface area (SSA) and pore volume than pure GO, with values of 374 m2 g?1 and 0.36 mL g?1, respectively. The GO?CNHox-K composite also exhibited a well-developed pore structure with an SSA of 271 m2 g?1 and pore volume of 0.26 mL g?1. These findings demonstrate that Ca2+ or K+ ions effectively link GO and CNHox, validating the success of this insertion approach in reducing GO aggregation. Metal ions played a crucial role in the insertion process by facilitating electrostatic interactions and coordination bonds between GO and CNHox. This study provides new insights into reducing GO agglomeration and expanding the application of GO-based materials. en-copyright= kn-copyright= en-aut-name=LiZhao en-aut-sei=Li en-aut-mei=Zhao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ToyotaMoeto en-aut-sei=Toyota en-aut-mei=Moeto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhkuboTakahiro en-aut-sei=Ohkubo en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=361 cd-vols= no-issue= article-no= start-page=114657 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=Crosstalk between prolactin, insulin-like growth factors, and thyroid hormones in feather growth regulation in neonatal chick wings en-subtitle= kn-subtitle= en-abstract= kn-abstract=The elongation of primary feathers in neonatal chicks is delayed by the late-feathering K gene located on the Z chromosome. We recently found that the K gene slows feather growth by reducing the number of functional prolactin (PRL) receptor (PRLR) dimers. In this study, we investigated the molecular mechanisms by which PRL promotes feather elongation. RT-qPCR and immunohistochemistry analyses revealed that PRLRs are predominantly localized in the pulp rather than in the epidermal layer of the feather follicle. Treatment of primary cultured feather pulp cells with PRL increased the expression of mRNAs for insulin-like growth factors (IGFs; IGF-1 and IGF-2) and type 2 deiodinase (DIO2). Furthermore, treatments with IGF-1 and triiodothyronine (T3) reciprocally enhanced the expression of mRNAs for DIO2 and IGFs. Additionally, BrdU staining in neonatal chicks showed that T3 promoted cell proliferation in both the epidermal layer and pulp cells, while this effect was suppressed by an IGF-1 receptor (IGF1R) inhibitor. These findings suggest a novel model in which PRL upregulates IGFs and DIO2 in feather pulp cells, creating a positive feedback loop between IGFs and T3, ultimately leading to the promotion of cell proliferation in both the epidermal layer and the pulp cells by IGFs. This is the first report proposing crosstalk between PRL, thyroid hormone (TH), and IGFs in feather follicles. en-copyright= kn-copyright= en-aut-name=NozawaYuri en-aut-sei=Nozawa en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkamuraAyako en-aut-sei=Okamura en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukuchiHibiki en-aut-sei=Fukuchi en-aut-mei=Hibiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShinoharaMasamichi en-aut-sei=Shinohara en-aut-mei=Masamichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=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 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=Prolactin kn-keyword=Prolactin en-keyword=Thyroid hormone kn-keyword=Thyroid hormone en-keyword=IGF kn-keyword=IGF en-keyword=Iodothyronine deiodinase kn-keyword=Iodothyronine deiodinase en-keyword=Feather growth kn-keyword=Feather growth END start-ver=1.4 cd-journal=joma no-vol=941 cd-vols= no-issue= article-no= start-page=149244 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250315 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Identification of pennaceous barbule cell factor (PBCF), a novel gene with spatiotemporal expression in barbule cells during feather development en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bird contour feathers exhibit a complex hierarchical structure composed of a rachis, barbs, and barbules, with barbules playing a crucial role in maintaining feather structure and function. Understanding the molecular mechanisms underlying barbule formation is essential for advancing our knowledge of avian biology and evolution. In this study, we identified a novel gene, pennaceous barbule cell factor (PBCF), using microarray analysis, RT-PCR, and in situ hybridization. PBCF is expressed in barbule cells adjacent to the ramus during pennaceous barbule formation, where these cells fuse with the ramus to establish the featherfs branching structure. PBCF expression occurs transiently after melanin pigmentation of the barbule plates but before the expression of barbule-specific keratin 1 (BlSK1). Orthologues of PBCF, predicted to be secreted proteins, are conserved across avian species, with potential homologues detected in reptiles, suggesting an evolutionary lineage-specific adaptation. Additionally, PBCF is expressed in non-vacuolated notochord cells and the extra-embryonic ectoderm of the yolk sac, hinting at its broader developmental significance. The PBCF gene produces two mRNA isoforms via alternative splicing, encoding a secreted protein and a glycophosphatidylinositol (GPI)-anchored membrane-bound protein, indicating functional versatility. These findings suggest that PBCF may be involved as an avian-specific extracellular matrix component in cell adhesion and/or communication, potentially contributing to both feather development and embryogenesis. Further investigation of PBCFfs role in feather evolution and its potential functions in other vertebrates could provide new insights into the interplay between development and evolution. en-copyright= kn-copyright= en-aut-name=NakaokaMinori en-aut-sei=Nakaoka en-aut-mei=Minori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukuchiHibiki en-aut-sei=Fukuchi en-aut-mei=Hibiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OgoshiMaho en-aut-sei=Ogoshi en-aut-mei=Maho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AizawaSayaka en-aut-sei=Aizawa en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakeuchiSakae en-aut-sei=Takeuchi en-aut-mei=Sakae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Feather kn-keyword=Feather en-keyword=Barbule kn-keyword=Barbule en-keyword=Branching kn-keyword=Branching en-keyword=Chicken kn-keyword=Chicken en-keyword=Yolk sac membrane kn-keyword=Yolk sac membrane en-keyword=Notochord kn-keyword=Notochord 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=129 cd-vols= no-issue=2 article-no= start-page=726 end-page=735 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=Hydronium Ions Are Less Excluded from Hydrophobic Polymer?Water Interfaces than Hydroxide Ions en-subtitle= kn-subtitle= en-abstract= kn-abstract=The cloud point temperatures of aqueous poly(N-isopropylacrylamide) (PNIPAM) and poly(ethylene) oxide (PEO) solutions were measured from pH 1.0 to pH 13.0 at a constant ionic strength of 100 mM. This ionic strength was reached by mixing the appropriate concentration of NaCl with either HCl or NaOH. The phase transition temperature of both polymers was nearly constant between pH 2.0 and 12.0. However, the introduction of 100 mM HCl (pH 1.0) led to an increase in the cloud point temperature, although this value was still lower than the cloud point temperature in the absence of salt. By contrast, the introduction of 100 mM NaOH (pH 13.0) caused a decrease in the cloud point temperature, both relative to adding 100 mM NaCl and adding no salt. Nuclear magnetic resonance (NMR) studies of these systems were performed below the cloud point temperature, and the chemical shifts closely tracked the corresponding changes in the phase transition temperature. Specifically, the introduction of 100 mM HCl caused the 1H chemical shift to move downfield for the CH resonances from both PNIPAM and PEO, while 100 mM NaOH caused the same resonances to move upfield. Virtually no change in the chemical shift was seen between pH 2.0 and 12.0. These results are consistent with the idea that a sufficient concentration of H3O+ led to polymer swelling compared to Na+, while substituting Cl? with OH? reduced swelling. Finally, classical all-atom molecular dynamics (MD) simulations were performed with a monomer and 5-mer corresponding to PNIPAM. The results correlated closely with the thermodynamic and spectroscopic data. The simulation showed that H3O+ ions more readily accumulated around the amide oxygen moiety on PNIPAM compared with Na+. On the other hand, OH? was more excluded from the polymer surface than Cl?. Taken together, the thermodynamic, spectroscopic, and MD simulation data revealed that H3O+ was less depleted from hydrophobic polymer/water interfaces than any of the monovalent Hofmeister metal cations or even Ca2+ and Mg2+. As such, it should be placed on the far-right side of the cationic Hofmeister series. On the other hand, OH? was excluded from the interface and could be positioned in the anionic Hofmeister series between H2PO4? and SO42?. en-copyright= kn-copyright= en-aut-name=MyersRyan L. en-aut-sei=Myers en-aut-mei=Ryan L. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TairaAoi en-aut-sei=Taira en-aut-mei=Aoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YanChuanyu en-aut-sei=Yan en-aut-mei=Chuanyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LeeSeung-Yi en-aut-sei=Lee en-aut-mei=Seung-Yi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WelshLauren K. en-aut-sei=Welsh en-aut-mei=Lauren K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IaniroPatrick R. en-aut-sei=Ianiro en-aut-mei=Patrick R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YangTinglu en-aut-sei=Yang en-aut-mei=Tinglu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KogaKenichiro en-aut-sei=Koga en-aut-mei=Kenichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=CremerPaul S. en-aut-sei=Cremer en-aut-mei=Paul S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Chemistry, The Pennsylvania State University, University Park kn-affil= affil-num=2 en-affil=Department of Chemistry, Okayama University kn-affil= affil-num=3 en-affil=Department of Chemistry, The Pennsylvania State University, University Park kn-affil= affil-num=4 en-affil=Department of Chemistry, The Pennsylvania State University, University Park kn-affil= affil-num=5 en-affil=Department of Chemistry, The Pennsylvania State University, University Park kn-affil= affil-num=6 en-affil=Department of Chemistry, University of Pittsburgh at Bradford kn-affil= affil-num=7 en-affil=Department of Chemistry, The Pennsylvania State University, University Park kn-affil= affil-num=8 en-affil=Department of Chemistry, Okayama University kn-affil= affil-num=9 en-affil=Department of Chemistry, The Pennsylvania State University, University Park kn-affil= END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=60 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250106 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Novel Drug Delivery Particles Can Provide Dual Effects on Cancer "Theranostics" in Boron Neutron Capture Therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Boron (B) neutron capture therapy (BNCT) is a novel non-invasive targeted cancer therapy based on the nuclear capture reaction 10B (n, alpha) 7Li that enables the death of cancer cells without damaging neighboring normal cells. However, the development of clinically approved boron drugs remains challenging. We have previously reported on self-forming nanoparticles for drug delivery consisting of a biodegradable polymer, namely, gAB-typeh Lactosome? nanoparticles (AB-Lac particles)- highly loaded with hydrophobic B compounds, namely o-Carborane (Carb) or 1,2-dihexyl-o-Carborane (diC6-Carb), and the latter (diC6-Carb) especially showed the gmolecular glueh effect. Here we present in vivo and ex vivo studies with human pancreatic cancer (AsPC-1) cells to find therapeutically optimal formulas and the appropriate treatment conditions for these particles. The biodistribution of the particles was assessed by the tumor/normal tissue ratio (T/N) in terms of tumor/muscle (T/M) and tumor/blood (T/B) ratios using near-infrared fluorescence (NIRF) imaging with indocyanine green (ICG). The in vivo and ex vivo accumulation of B delivered by the injected AB-Lac particles in tumor lesions reached a maximum by 12 h post-injection. Irradiation studies conducted both in vitro and in vivo showed that AB-Lac particles-loaded with either 10B-Carb or 10B-diC6-Carb significantly inhibited the growth of AsPC-1 cancer cells or strongly inhibited their growth, with the latter method being significantly more effective. Surprisingly, a similar in vitro and in vivo irradiation study showed that ICG-labeled AB-Lac particles alone, i.e., without any 10B compounds, also revealed a significant inhibition. Therefore, we expect that our ICG-labeled AB-Lac particles-loaded with 10B compound(s) may be a novel and promising candidate for providing not only NIRF imaging for a practical diagnosis but also the dual therapeutic effects of induced cancer cell death, i.e., gtheranosticsh. en-copyright= kn-copyright= en-aut-name=FithroniAbdul Basith en-aut-sei=Fithroni en-aut-mei=Abdul Basith kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=InoueHaruki en-aut-sei=Inoue en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ZhouShengli en-aut-sei=Zhou en-aut-mei=Shengli kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HakimTaufik Fatwa Nur en-aut-sei=Hakim en-aut-mei=Taufik Fatwa Nur kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TadaTakashi en-aut-sei=Tada en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuzukiMinoru en-aut-sei=Suzuki en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakuraiYoshinori en-aut-sei=Sakurai en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IshimotoManabu en-aut-sei=Ishimoto en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamadaNaoyuki en-aut-sei=Yamada en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SauriasariRani en-aut-sei=Sauriasari en-aut-mei=Rani kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SauerweinWolfgang A.

Therefore, XO inhibitors, which suppress oxidative stress, may effectively treat non-alcoholic steatohepatitis (NASH) and atherosclerosis via uric acid reduction. In this study, we examined the antioxidant effect of the XO inhibitor febuxostat on NASH and atherosclerosis in stroke-prone spontaneously hypertensive 5 (SHRSP5/Dmcr) rats.
Methods: SHRSP5/Dmcr rats were divided into three groups: SHRSP5/Dmcr + high-fat and high-cholesterol (HFC) diet [control group, n = 5], SHRSP5/Dmcr + HFC diet + 10% fructose (40 ml/day) [fructose group, n = 5], and SHRSP5/Dmcr + HFC diet + 10% fructose (40 ml/day) + febuxostat (1.0 mg/kg/day) [febuxostat group, n = 5]. Glucose and insulin resistance, blood biochemistry, histopathological staining, endothelial function, and oxidative stress markers were evaluated.
Results: Febuxostat reduced the plasma uric acid levels. Oxidative stress-related genes were downregulated, whereas antioxidant factor-related genes were upregulated in the febuxostat group compared with those in the fructose group. Febuxostat also ameliorated inflammation, fibrosis, and lipid accumulation in the liver. Mesenteric lipid deposition decreased in the arteries, and aortic endothelial function improved in the febuxostat group.
Conclusions: Overall, the XO inhibitor febuxostat exerted protective effects against NASH and atherosclerosis in SHRSP5/Dmcr rats. en-copyright= kn-copyright= en-aut-name=KakimotoMai en-aut-sei=Kakimoto en-aut-mei=Mai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiiMoe en-aut-sei=Fujii en-aut-mei=Moe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoIkumi en-aut-sei=Sato en-aut-mei=Ikumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HonmaKoki en-aut-sei=Honma en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakayamaHinako en-aut-sei=Nakayama en-aut-mei=Hinako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KiriharaSora en-aut-sei=Kirihara en-aut-mei=Sora kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FukuokaTaketo en-aut-sei=Fukuoka en-aut-mei=Taketo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=RanShang en-aut-sei=Ran en-aut-mei=Shang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HirohataSatoshi en-aut-sei=Hirohata en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KitamoriKazuya en-aut-sei=Kitamori en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YamamotoShusei en-aut-sei=Yamamoto en-aut-mei=Shusei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=WatanabeShogo en-aut-sei=Watanabe en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Okayama University, Graduate School of Health Sciences, Department of Medical Technology kn-affil= affil-num=2 en-affil=Okayama University, Graduate School of Health Sciences, Department of Medical Technology kn-affil= affil-num=3 en-affil=Okayama University, Graduate School of Health Sciences, Department of Medical Technology kn-affil= affil-num=4 en-affil=Okayama University, Graduate School of Health Sciences, Department of Medical Technology kn-affil= affil-num=5 en-affil=Okayama University, Graduate School of Health Sciences, Department of Medical Technology kn-affil= affil-num=6 en-affil=Okayama University, Graduate School of Health Sciences, Department of Medical Technology kn-affil= affil-num=7 en-affil=Okayama University, Faculty of Health Sciences, Department of Medical Technology kn-affil= affil-num=8 en-affil=Okayama University, Graduate School of Health Sciences, Department of Medical Technology kn-affil= affil-num=9 en-affil=Okayama University, Academic Field of Health Science kn-affil= affil-num=10 en-affil=Kinjo Gakuin University, College of Human Life and Environment kn-affil= affil-num=11 en-affil=Okayama University, Graduate School of Health Sciences, Department of Medical Technology kn-affil= affil-num=12 en-affil=Okayama University, Academic Field of Health Science kn-affil= en-keyword=Anti-inflammatory kn-keyword=Anti-inflammatory en-keyword=Atherosclerosis kn-keyword=Atherosclerosis en-keyword=Febuxostat kn-keyword=Febuxostat en-keyword=Non-alcoholic steatohepatitis (NASH) kn-keyword=Non-alcoholic steatohepatitis (NASH) en-keyword=Oxidative stress kn-keyword=Oxidative stress en-keyword=Uric acid kn-keyword=Uric acid END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=29 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=The Three-Class Annotation Method Improves the AI Detection of Early-Stage Osteosarcoma on Plain Radiographs: A Novel Approach for Rare Cancer Diagnosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Developing high-performance artificial intelligence (AI) models for rare diseases is challenging owing to limited data availability. This study aimed to evaluate whether a novel three-class annotation method for preparing training data could enhance AI model performance in detecting osteosarcoma on plain radiographs compared to conventional single-class annotation. Methods: We developed two annotation methods for the same dataset of 468 osteosarcoma X-rays and 378 normal radiographs: a conventional single-class annotation (1C model) and a novel three-class annotation method (3C model) that separately labeled intramedullary, cortical, and extramedullary tumor components. Both models used identical U-Net-based architectures, differing only in their annotation approaches. Performance was evaluated using an independent validation dataset. Results: Although both models achieved high diagnostic accuracy (AUC: 0.99 vs. 0.98), the 3C model demonstrated superior operational characteristics. At a standardized cutoff value of 0.2, the 3C model maintained balanced performance (sensitivity: 93.28%, specificity: 92.21%), whereas the 1C model showed compromised specificity (83.58%) despite high sensitivity (98.88%). Notably, at the 25th percentile threshold, both models showed identical false-negative rates despite significantly different cutoff values (3C: 0.661 vs. 1C: 0.985), indicating the ability of the 3C model to maintain diagnostic accuracy at substantially lower thresholds. Conclusions: This study demonstrated that anatomically informed three-class annotation can enhance AI model performance for rare disease detection without requiring additional training data.

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=E108-B cd-vols= no-issue=1 article-no= start-page=1 end-page=13 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Overloaded MIMO Spatial Multiplexing Independent of Antenna Setups en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper proposes overloaded MIMO spatial multiplexing that can increase the number of spatially multiplexed signal streams despite of the number of antennas on a terminal and that on a receiver. We propose extension of the channel matrix for the spatial multiplexing to achieve the superb multiplexing performance. Precoding based on the extended channel matrix plays a crucial role in carrying out such spatial multiplexing. We consider three types of QR-decomposition techniques for the proposed spatial multiplexing to improve the transmission performance. The transmission performance of the proposed spatial multiplexing is evaluated by computer simulation. The simulation reveals that the proposed overloaded MIMO spatial multiplexing can implement 6 stream-spatial multiplexing in a 2~2 MIMO system, i.e., the overloading ratio of 3.0. The superior transmission performance is achieved by the proposed overloaded MIMO spatial multiplexing with one of the QR-decomposition techniques. en-copyright= kn-copyright= en-aut-name=DennoSatoshi en-aut-sei=Denno en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugimotoTakumi en-aut-sei=Sugimoto en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatobaKoki en-aut-sei=Matoba en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HouYafei en-aut-sei=Hou en-aut-mei=Yafei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=overloaded MIMO kn-keyword=overloaded MIMO en-keyword=spatial multiplexing kn-keyword=spatial multiplexing en-keyword=QR-decomposition kn-keyword=QR-decomposition en-keyword=precoding kn-keyword=precoding en-keyword=overloading ratio kn-keyword=overloading ratio END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=24 article-no= start-page=4878 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241211 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Implementation of Web-Based Answer Platform in the Flutter Programming Learning Assistant System Using Docker Compose en-subtitle= kn-subtitle= en-abstract= kn-abstract=Programming has gained significant importance worldwide as societies increasingly rely on computer application systems. To support novices in learning various programming languages, we have developed the Programming Learning Assistant System (PLAS). It offers several types of exercise problems with different learning goals and levels for step-by-step self-study. As a personal answer platform in PLAS, we have implemented a web application using Node.js and EJS for Java and Python programming. Recently, the Flutter framework with Dart programming has become popular, enabling developers to build applications for mobile, web, and desktop environments from a single codebase. Thus, we have extended PLAS by implementing the Flutter environment with Visual Studio Code to support it. Additionally, we have developed an image-based user interface (UI) testing tool to verify student source code by comparing its generated UI image with the standard one using the ORB and SIFT algorithms in OpenCV. For efficient distribution to students, we have generated Docker images of the answer platform, Flutter environment, and image-based UI testing tool. In this paper, we present the implementation of a web-based answer platform for the Flutter Programming Learning Assistant System (FPLAS) by integrating three Docker images using Docker Compose. Additionally, to capture UI images automatically, an Nginx web application server is adopted with its Docker image. For evaluations, we asked 10 graduate students at Okayama University, Japan, to install the answer platform on their PCs and solve five exercise problems. All the students successfully completed the problems, which confirms the validity and effectiveness of the proposed system. en-copyright= kn-copyright= en-aut-name=AungLynn Htet en-aut-sei=Aung en-aut-mei=Lynn Htet kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AungSoe Thandar en-aut-sei=Aung en-aut-mei=Soe Thandar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KyawHtoo Htoo Sandi en-aut-sei=Kyaw en-aut-mei=Htoo Htoo Sandi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KaoWen-Chung en-aut-sei=Kao en-aut-mei=Wen-Chung kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Computer and Information Science, Tokyo University of Agriculture and Technology kn-affil= affil-num=5 en-affil=Department of Electrical Engineering, National Taiwan Normal University kn-affil= en-keyword=Flutter kn-keyword=Flutter en-keyword=Dart kn-keyword=Dart en-keyword=answer platform kn-keyword=answer platform en-keyword=Flutter environment kn-keyword=Flutter environment en-keyword=Nginx kn-keyword=Nginx en-keyword=UI testing tool kn-keyword=UI testing tool en-keyword=Docker Compose kn-keyword=Docker Compose 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 ƒÊs (1.6 ms and 5.4 ƒÊs 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/ãHz. 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=14 cd-vols= no-issue=12 article-no= start-page=1258 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241215 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Impact of Selective Spatial Attention on Auditory-Tactile Integration: An Event-Related Potential Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Auditory-tactile integration is an important research area in multisensory integration. Especially in special environments (e.g., traffic noise and complex work environments), auditory-tactile integration is crucial for human response and decision making. We investigated the influence of attention on the temporal course and spatial distribution of auditory-tactile integration. Methods: Participants received auditory stimuli alone, tactile stimuli alone, and simultaneous auditory and tactile stimuli, which were randomly presented on the left or right side. For each block, participants attended to all stimuli on the designated side and detected uncommon target stimuli while ignoring all stimuli on the other side. Event-related potentials (ERPs) were recorded via 64 scalp electrodes. Integration was quantified by comparing the response to the combined stimulus to the sum of the responses to the auditory and tactile stimuli presented separately. Results: The results demonstrated that compared to the unattended condition, integration occurred earlier and involved more brain regions in the attended condition when the stimulus was presented in the left hemispace. The unattended condition involved a more extensive range of brain regions and occurred earlier than the attended condition when the stimulus was presented in the right hemispace. Conclusions: Attention can modulate auditory-tactile integration and show systematic differences between the left and right hemispaces. These findings contribute to the understanding of the mechanisms of auditory-tactile information processing in the human brain. en-copyright= kn-copyright= en-aut-name=AnWeichao en-aut-sei=An en-aut-mei=Weichao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZhangNan en-aut-sei=Zhang en-aut-mei=Nan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LiShengnan en-aut-sei=Li en-aut-mei=Shengnan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YuYinghua en-aut-sei=Yu en-aut-mei=Yinghua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WuJinglong en-aut-sei=Wu en-aut-mei=Jinglong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YangJiajia en-aut-sei=Yang en-aut-mei=Jiajia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=auditory-tactile integration kn-keyword=auditory-tactile integration en-keyword=selective spatial attention kn-keyword=selective spatial attention en-keyword=event-related potential kn-keyword=event-related potential en-keyword=left-right hemispace differences kn-keyword=left-right hemispace differences en-keyword=spatiotemporal distribution kn-keyword=spatiotemporal distribution END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=12 article-no= start-page=1184 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241126 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Contributions of the Primary Sensorimotor Cortex and Posterior Parietal Cortex to Motor Learning and Transfer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Transferring learned manipulations to new manipulation tasks has enabled humans to realize thousands of dexterous object manipulations in daily life. Two-digit grasp and three-digit grasp manipulations require different fingertip forces, and our brain can switch grasp types to ensure good performance according to motor memory. We hypothesized that several brain areas contribute to the execution of the new type of motor according to the motor memory. However, the motor memory mechanisms during this transfer period are still unclear. In the present functional magnetic resonance imaging (fMRI) study, we aimed to investigate the cortical mechanisms involved in motor memory during the transfer phase of learned manipulation tasks. Methods: Using a custom-built T-shaped object with an adjustable weight distribution, the participants performed grasp and lift manipulation tasks under different conditions to simulate the learning and transfer phases. The learning phase consisted of four grasp-and-lift repetitions with one motor type, followed by a transfer phase with four repetitions involving different motors (adding or removing a digit). Results: By comparing brain activity in the learning and transfer phases, we identified three regions (the superior frontal gyrus, supramarginal gyrus, and postcentral gyrus) associated with motor memory during the transfer of learned manipulations. Conclusions: Our findings improve the understanding of the role of the posterior parietal cortex in motor memory, highlighting how sensory information from memory and real-time input is integrated to generate novel motor control signals that guide the precise reapplication of control strategies. Furthermore, we believe that these areas contribute to motor learning from motor memory and may serve as key regions of interest for investigating neurodegenerative diseases. en-copyright= kn-copyright= en-aut-name=WangChenyu en-aut-sei=Wang en-aut-mei=Chenyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YuYinghua en-aut-sei=Yu en-aut-mei=Yinghua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YangJiajia en-aut-sei=Yang en-aut-mei=Jiajia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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= en-keyword=fMRI kn-keyword=fMRI en-keyword=motor learning and transfer kn-keyword=motor learning and transfer en-keyword=primary sensorimotor cortex kn-keyword=primary sensorimotor cortex en-keyword=posterior parietal cortex kn-keyword=posterior parietal cortex END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=12 article-no= start-page=789 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241209 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Yoga Pose Difficulty Level Estimation Method Using OpenPose for Self-Practice System to Yoga Beginners en-subtitle= kn-subtitle= en-abstract= kn-abstract=Yoga is an exercise preferable for various users at different ages to enhance physical and mental health. To help beginner yoga self-practitioners avoid getting injured by selecting difficult yoga poses, the information of the difficulty level of yoga poses is very important to provide an objective metric to assist yoga self-practitioners in selecting appropriate exercises on the basis of their skill level by using the yoga self-practice system. To enhance the developed yoga self-practice system, the yoga difficulty level estimation function will enable users to clearly understand whether the selected yoga poses are suitable for them. In this paper, the newest difficulty level estimation method of yoga poses is proposed by using and analyzing OpenPose two-dimensional (2D) human body keypoints. The proposed method effectively uses the selected six keypoints areas of the upper and lower body, body support types, center of gravity calculations, and body tilt angles and slopes to produce estimations. Firstly, the method calculates the weighted centers of the upper and lower human body for each pose by using keypoints. Secondly, it refers the slope of the centroid line between the two centers and infers the body's balance state. Lastly, the system estimates the difficulty level by additionally considering the keypoints of the body to contact the ground. For evaluations of the proposal, more than one hundred yoga poses are collected from the Internet and applied to classify them into five difficulty levels. Through comparisons with subjective levels from one instructor and 10 users, the validity of the estimation results is confirmed, a comparison is performed with existing designs, and it is implemented in embedded systems. en-copyright= kn-copyright= en-aut-name=ShihCheng-Liang en-aut-sei=Shih en-aut-mei=Cheng-Liang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LiuJun-You en-aut-sei=Liu en-aut-mei=Jun-You kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AnggrainiIrin Tri en-aut-sei=Anggraini en-aut-mei=Irin Tri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=XiaoYanqi en-aut-sei=Xiao en-aut-mei=Yanqi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FanChih-Peng en-aut-sei=Fan en-aut-mei=Chih-Peng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Electrical Engineering, National Chung Hsing University kn-affil= affil-num=2 en-affil=Department of Electrical Engineering, National Chung Hsing University kn-affil= affil-num=3 en-affil=Department of Electrical and Communication Engineering, Okayama University kn-affil= affil-num=4 en-affil=Department of Electrical and Communication Engineering, Okayama University kn-affil= affil-num=5 en-affil=Department of Electrical and Communication Engineering, Okayama University kn-affil= affil-num=6 en-affil=Department of Electrical Engineering, National Chung Hsing University kn-affil= en-keyword=yoga kn-keyword=yoga en-keyword=self-practice kn-keyword=self-practice en-keyword=OpenPose kn-keyword=OpenPose en-keyword=pose difficulty level kn-keyword=pose difficulty level en-keyword=body keypoint kn-keyword=body keypoint 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

However, such predictions often rely on empirical knowledge, which may limit inexperienced engineers to reliably obtain accurate predictions. This study explores a method to predict the tool life of a cutting machine using servo motor current data collected during the initial stages of tool wear, which is a cost-effective approach. The LightGBM model was identified as suitable for predicting tool life from current data, given the challenges associated with predicting from the average variation of current values. By identifying and utilizing the top 50 features from the current data for prediction, the accuracy of tool life prediction in the early wear stage improved. As this prediction method was developed based on current data obtained during the very early wear stage in experiments with square end-mills, it was tested on extrapolated data using different end-mill diameters. The findings revealed average accuracy rates of 71.2% and 69.4% when using maximum machining time and maximum removal volume as thresholds, respectively. en-copyright= kn-copyright= en-aut-name=KODAMAHiroyuki en-aut-sei=KODAMA en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SUZUKIMakoto en-aut-sei=SUZUKI en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OHASHIKazuhito en-aut-sei=OHASHI en-aut-mei=Kazuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate school of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Milling kn-keyword=Milling en-keyword=LightGBM kn-keyword=LightGBM en-keyword=Tool life prediction kn-keyword=Tool life prediction en-keyword=Square end-mill kn-keyword=Square end-mill en-keyword=Servo motor current kn-keyword=Servo motor current END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e202404400 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250107 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Graphene Oxide as a Self]Carbocatalyst to Facilitate the Ring]Opening Polymerization of Glycidol for Efficient Polyglycerol Grafting en-subtitle= kn-subtitle= en-abstract= kn-abstract=Grafting carbon-based nanomaterials (CNMs) with polyglycerol (PG) improves their application potentials in biomedicine and electronics. Although ggrafting fromh method offers advantages over ggrafting toh one in terms of operability and versatility, little is known about the reaction process of glycidol with the surface groups onto CNMs. By using graphene oxide (GO) as a multi-functional model material, we examined the reactivity of the surface groups on GO toward glycidol molecules via a set of model reactions. We reveal that carboxyl groups spontaneously react with the epoxide ring with no need of catalyst, while GO catalyzes the reactions of hydroxyl groups with the epoxide of glycidol. In addition, the hydroxyl group of glycidol can open the epoxide in the basal plane of GO. The subsequent polymerization of PG is supposed to propagate at the primary and/or the secondary hydroxyl groups, generating a ramified PG macromolecule with random branch-on-branch topology. In addition, ketones, benzyl esters and aromatic ethers are found not to react with glycidol even in the presence of GO, while the aldehydes are easily oxidized into carboxyl groups under ambient condition, behaving then as the carboxyl groups. Our findings pose the foundation for understanding the polymerization mechanism of PG on CNMs. en-copyright= kn-copyright= en-aut-name=ZouYajuan en-aut-sei=Zou en-aut-mei=Yajuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhkuraKentaro en-aut-sei=Ohkura en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Ortiz]AnayaIsrael en-aut-sei=Ortiz]Anaya en-aut-mei=Israel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KimuraRyota en-aut-sei=Kimura en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BiancoAlberto en-aut-sei=Bianco en-aut-mei=Alberto 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=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=Carbon nanomaterials kn-keyword=Carbon nanomaterials en-keyword=Epoxide ring-opening kn-keyword=Epoxide ring-opening en-keyword=Catalysis kn-keyword=Catalysis en-keyword=Polyglycerol functionalization kn-keyword=Polyglycerol functionalization END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=3 article-no= start-page=620 end-page=626 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=2023 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=All-in-one terahertz taste sensor: integrated electronic and bioelectronic tongues en-subtitle= kn-subtitle= en-abstract= kn-abstract=Taste sensors, also known as electronic tongues or bioelectronic tongues, are designed to evaluate food and beverages, as well as for medical diagnostics. These devices mimic the ability of the human tongue to detect and identify different tastes in liquid samples, such as sweet, sour, salty, bitter, and umami. In this study, a novel all-in-one terahertz taste sensor was proposed, which differs from traditional electrochemical approaches. This sensor utilizes terahertz technology for imaging and sensing chemical reactions on the terahertz semiconductor emitter surface. The surface can be functionalized with ion-sensitive membranes, proteins, DNA aptamers, and organic receptors, enabling the detection of various substances, such as solution pH, physiological ions, sugars, toxic chemicals, drugs, and explosives. Terahertz taste sensors offer several advantages, including being label-free, high sensitivity and selectivity, rapid response, minimal sample consumption, and the ability to detect non-charged chemical substances. By integrating multiple receptors or sensing materials on a single chip, the all-in-one terahertz taste sensor has significant potential for future taste substance detection, nutrition evaluation, metabolite and drug monitoring, and biomarker sensing. en-copyright= kn-copyright= en-aut-name=WangJin en-aut-sei=Wang en-aut-mei=Jin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakaiKenji en-aut-sei=Sakai en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KiwaToshihiko en-aut-sei=Kiwa en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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= END start-ver=1.4 cd-journal=joma no-vol=35 cd-vols= no-issue=1 article-no= start-page=65 end-page=73 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of Automatic Inspection Systems for WRS2020 Plant Disaster Prevention Challenge Using Image Processing en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this article, an approach used for the inspection tasks in the WRS2020 Plant Disaster Prevention Challenge is explained. The tasks were categorized into three categories: reading pressure gauges, inspecting rust on a tank, and inspecting cracks in a tank. For reading pressure gauges, the gyou only look onceh algorithm was used to focus on a specific pressure gauge and check the pressure gauge range strings on the gauge using optical character recognition algorithm. Finally, a previously learned classifier was used to read the values shown in the gauge. For rust inspection, image processes were used to focus on a target plate that may be rusted for rust detection. In particular, it was necessary to report the rust area and distribution type. Thus, the pixel ratio and grouping of rust were used to count the rust. The approach for crack inspection was similar to that for rust. The target plate was focused on first, and then the length of the crack was measured using image processing. Its width was not measured but was calculated using the crack area and length. For each system developed to approach each task, the results of the preliminary experiment and those of WRS2020 are shown. Finally, the approaches are summarized, and planned future work is discussed. en-copyright= kn-copyright= en-aut-name=ShimizuYuya en-aut-sei=Shimizu en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KamegawaTetsushi en-aut-sei=Kamegawa en-aut-mei=Tetsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WangYongdong en-aut-sei=Wang en-aut-mei=Yongdong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TamuraHajime en-aut-sei=Tamura en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TeshimaTaiga en-aut-sei=Teshima en-aut-mei=Taiga kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakanoSota en-aut-sei=Nakano en-aut-mei=Sota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TadaYuki en-aut-sei=Tada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakanoDaiki en-aut-sei=Nakano en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SasakiYuichi en-aut-sei=Sasaki en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SekitoTaiga en-aut-sei=Sekito en-aut-mei=Taiga kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=UtsumiKeisuke en-aut-sei=Utsumi en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NagaoRai en-aut-sei=Nagao en-aut-mei=Rai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=SembaMizuki en-aut-sei=Semba en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Okayama University kn-affil= affil-num=3 en-affil=Okayama University kn-affil= affil-num=4 en-affil=Okayama University kn-affil= affil-num=5 en-affil=Okayama University kn-affil= affil-num=6 en-affil=Okayama University kn-affil= affil-num=7 en-affil=Okayama University kn-affil= affil-num=8 en-affil=Okayama University kn-affil= affil-num=9 en-affil=Okayama University kn-affil= affil-num=10 en-affil=Okayama University kn-affil= affil-num=11 en-affil=Okayama University kn-affil= affil-num=12 en-affil=Okayama University kn-affil= affil-num=13 en-affil=Okayama University kn-affil= en-keyword=WRS2020 kn-keyword=WRS2020 en-keyword=image processing kn-keyword=image processing en-keyword=auto inspection kn-keyword=auto inspection en-keyword=YOLO kn-keyword=YOLO en-keyword=OCR kn-keyword=OCR END start-ver=1.4 cd-journal=joma no-vol=222 cd-vols= no-issue= article-no= start-page=115374 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Environmental water in Kolkata is suitable for the survival of Vibrio cholerae O1 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Many patients with cholera emerge in Kolkata, India throughout the year. 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 start-ver=1.4 cd-journal=joma no-vol=391 cd-vols= no-issue= article-no= start-page=158 end-page=176 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250215 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Magnesium isotope composition of volcanic rocks from cold and warm subduction zones: Implications for the recycling of subducted serpentinites and carbonates en-subtitle= kn-subtitle= en-abstract= kn-abstract=Magnesium (Mg) isotopes are regarded as a sensitive tracer to the contribution from subducted serpentinites and carbonates. However, the source, distribution, and controlling factors of the Mg isotope composition of arc magmas remain unclear. In this study, we investigated the intra-arc and inter-arc variations in Mg isotope compositions of volcanic rocks from two typical cold subduction zones [NE Japan (NEJ) and Izu arcs] and a typical hot subduction zone [SW Japan (SWJ) arc] to address the question. The volcanic rocks from the frontal-arc regions of NEJ and Izu have isotopically heavy Mg (ƒÂ26Mg = ?0.20 to ?0.08 ñ) compared to the mantle-like ƒÂ26Mg values of most of volcanic rocks from SWJ and the rear regions of NEJ and Izu arcs (?0.28 to ?0.17 ñ). It is also worth noting that NEJ arc includes samples with ƒÂ26Mg values (?0.61 to ?0.39 ñ) significantly lower than the mantle, but similar to the < 110 Ma intra-continental basalts from eastern China, which is the first observation in modern arc rocks. No obvious effects of post-eruptive alteration, fractional crystallization, partial melting, or the addition of silicate-rich sediment and oceanic crust components could be identified in the Mg isotope compositions of these volcanic rocks. By contrast, the correlations between the ƒÂ26Mg values and the proxy for serpentinite component (i.e., 11B/10B and Nb/B ratios) indicate that the component exerts a strong control on the Mg-isotopic signature of these arc rocks. Considering metamorphic reactions in subduction lithologies under P-T conditions postulated for these arcs, the variations in ƒÂ26Mg values of these arc magmas are unlikely to have been controlled by dehydration of serpentinites in subducted oceanic lithosphere (slab serpentinite). Instead, the high-ƒÂ26Mg values of frontal-arc rocks are delivered by the fluids from serpentinite formed in the lowermost part of the sub-arc mantle (mantle wedge serpentinite) in channelized flow. Comparatively, such a high-ƒÂ26Mg signature is invisible in volcanic rocks from rear-arc regions of NEJ and Izu, and the entire SWJ, suggesting that the major Mg carriers in subducted serpentinites (e.g., talc, chlorite, and serpentine) were broken down completely before subducted slabs reached the depth beneath these volcanoes. Moreover, the volcanic rocks with low ƒÂ26Mg values from the rear arc of NEJ are characterized by high La/Yb and U/Nb ratios as well as low Ti/Eu, Ti/Ti*, and Hf/Hf* ratios, suggesting the involvements of carbonates in their magma sources. The quantitative modeling suggests that < 20 % of sedimentary carbonate (dolomite) was recycled into their mantle source, revealing that Mg-rich carbonate could be incorporated into a deep mantle wedge at rear-arc depths of 150?400 km in subduction zones. en-copyright= kn-copyright= en-aut-name=ZhangWei en-aut-sei=Zhang en-aut-mei=Wei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitagawaHiroshi en-aut-sei=Kitagawa en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HuangFang en-aut-sei=Huang en-aut-mei=Fang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 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= en-keyword=Magnesium isotopes kn-keyword=Magnesium isotopes en-keyword=Arc magmas kn-keyword=Arc magmas en-keyword=Mantle wedge serpentinite kn-keyword=Mantle wedge serpentinite en-keyword=Slab serpentinite kn-keyword=Slab serpentinite en-keyword=Carbonate recycle kn-keyword=Carbonate recycle END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=1 article-no= start-page=24 end-page=28 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202407 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Initial trial of three?lead wearable electrocardiogram monitoring in a full marathon en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sudden cardiac arrest during exercise can occur without prior warning signs at rest, highlighting the importance of monitoring for its prevention. To detect the signs of ischemic heart disease, including coronary artery anomalies, ST changes must be detected using three?lead electrocardiograms (ECGs) corresponding to each region of the three coronary artery branches. We conducted ECG monitoring of five runners during a marathon using a wearable three?lead ECG device (e-skin ECG; Xenoma Inc., Tokyo, Japan). Data without noise or artifacts were successfully collected for one of five runners during the entire marathon. Within the initial hour of the marathon, poor electrode adhesion to the skin hindered the data collection for the remaining four runners, which resulted in significantly decreased acquisition rate compared with the first hour (86.7?}?13.4?% to 37.3?}?36.9?%, p?=?0.028). Couplets of premature ventricular contractions with clear ECG waveforms in the three leads were detected in one runner during the marathon. Further device improvements are necessary to enable marathon runners to obtain ECGs efficiently without affecting their performance. This study also demonstrated the potential applications of three?lead wearable ECG monitoring for other short-duration sports and remote home-based cardiac rehabilitation. en-copyright= kn-copyright= en-aut-name=HiraiKenta en-aut-sei=Hirai en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakanoNoriko en-aut-sei=Sakano en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OozawaSusumu en-aut-sei=Oozawa en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OusakaDaiki en-aut-sei=Ousaka en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KurokoYosuke en-aut-sei=Kuroko en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KasaharaShingo en-aut-sei=Kasahara en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Science kn-affil= affil-num=2 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Science kn-affil= affil-num=3 en-affil=Department of Clinical Safety, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pharmacology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Science kn-affil= affil-num=5 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Science kn-affil= affil-num=6 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Science kn-affil= en-keyword=Sudden cardiac arrest kn-keyword=Sudden cardiac arrest en-keyword=Sports cardiology kn-keyword=Sports cardiology en-keyword=Electrocardiogram kn-keyword=Electrocardiogram en-keyword=Wearable device kn-keyword=Wearable device en-keyword=Cardiac rehabilitation kn-keyword=Cardiac rehabilitation en-keyword=Coronary artery anomalies kn-keyword=Coronary artery anomalies END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=3-4 article-no= start-page=116 end-page=125 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241230 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Deep Reinforcement Learning Enabled Adaptive Virtual Machine Migration Control in Multi-Stage Information Processing Systems en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper tackles a Virtual Machine (VM) migration control problem to maximize the progress (accuracy) of information processing tasks in multi-stage information processing systems. The conventional methods for this problem are effective only for specific situations, such as when the system load is high. In this paper, in order to adaptively achieve high accuracy in various situations, we propose a VM migration method using a Deep Reinforcement Learning (DRL) algorithm. It is difficult to directly apply a DRL algorithm to the VM migration control problem because the size of the solution space of the problem dynamically changes according to the number of VMs staying in the system while the size of the agentfs action space is fixed in DRL algorithms. To cope with this difficulty, the proposed method divides the VM migration control problem into two problems: the problem of determining only the VM distribution (i.e., the proportion of the number of VMs deployed on each edge server) and the problem of determining the locations of all the VMs so that it follows the determined VM distribution. The former problem is solved by a DRL algorithm, and the latter by a heuristic method. This approach makes it possible to apply a DRL algorithm to the VM migration control problem because the VM distribution is expressed by a vector with a fixed number of dimensions and can be directly outputted by the agent. The simulation results confirm that our proposed method can adaptively achieve quasi-optimal accuracy in various situations with different link delays, types of the information processing tasks and the number of VMs. en-copyright= kn-copyright= en-aut-name=FukushimaYukinobu en-aut-sei=Fukushima en-aut-mei=Yukinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KoujitaniYuki en-aut-sei=Koujitani en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakaneKazutoshi en-aut-sei=Nakane en-aut-mei=Kazutoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TarutaniYuya en-aut-sei=Tarutani en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WuCelimuge en-aut-sei=Wu en-aut-mei=Celimuge kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=JiYusheng en-aut-sei=Ji en-aut-mei=Yusheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YokohiraTokumi en-aut-sei=Yokohira en-aut-mei=Tokumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MuraseTutomu en-aut-sei=Murase en-aut-mei=Tutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Information Science Nagoya University kn-affil= affil-num=4 en-affil=Graduate School of Engineering Osaka University kn-affil= affil-num=5 en-affil=Graduate School of Informatics and Engineering The Univ. of Electro-Commun. kn-affil= affil-num=6 en-affil=Information Systems Architecture Research Division National Institute of Informatics kn-affil= affil-num=7 en-affil=Faculty of Interdisciplinary Science and Engineering in Health Systems Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Information Science Nagoya University kn-affil= en-keyword=Multi-stage information processing system kn-keyword=Multi-stage information processing system en-keyword=VM migration control kn-keyword=VM migration control en-keyword=Deep reinforcement learning kn-keyword=Deep reinforcement learning en-keyword=Deep Deterministic Policy Gradient (DDPG) kn-keyword=Deep Deterministic Policy Gradient (DDPG) END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue= article-no= start-page=19 end-page=52 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Mineralogy and geochemistry of magnetite-garnet bearing skarn deposits surrounding iron-smelting sites in the Kibi region of Japan kn-title=‹g”õ»“SˆâÕŽü•Ó’nˆæ‚ÌŽ¥“Sz‚´‚­‚ë΃XƒJƒ‹ƒ““Sz΂Ìz•¨Šw“IE’n‹…‰»Šw“I“Á’¥ en-subtitle= kn-subtitle= en-abstract= kn-abstract=We conducted mineralogical and geochemical analysis of ore samples taken from locations surrounding the Jinmu, Sanp?, and K?moto mines in order to determine the source of iron ore uncovered from archaeological sites. The mineral composition of the magnetite-garnet bearing skarn deposits varies from mine to mine: while clinopyroxene and amphibole are present in the Jinmu and Sanp? samples, only a small amount of clinopyroxene occurs in the K?moto samples. The chemical compositions of magnetite and garnet are distinctive for each mine. Among the trace elements contained in the magnetite, Mg and Mn tend to be higher in the K?moto samples, Ti in the Jinmu samples, and Ca and Si in the Sanp? samples. The garnet from all the mines is andradite, but while the K?moto samples contain almost no Al, it is present in the Jinmu and Sanp? samples. Although samples were taken from a limited number of mine areas (three), our analysis provides an index for comparison with iron ore uncovered from archaeological sites, which will aid in provenance determination. en-copyright= kn-copyright= en-aut-name=TAKECHIYasushi en-aut-sei=TAKECHI en-aut-mei=Yasushi kn-aut-name=•’q‘׎j kn-aut-sei=•’q kn-aut-mei=‘׎j aut-affil-num=1 ORCID= en-aut-name=NAKAMURADaisuke en-aut-sei=NAKAMURA en-aut-mei=Daisuke kn-aut-name=’†‘º‘å•ã kn-aut-sei=’†‘º kn-aut-mei=‘å•ã aut-affil-num=2 ORCID= en-aut-name=SUZUKIShigeyuki en-aut-sei=SUZUKI en-aut-mei=Shigeyuki kn-aut-name=—é–ؖΔV kn-aut-sei=—é–Ø kn-aut-mei=–ΔV aut-affil-num=3 ORCID= en-aut-name=RYANJoseph en-aut-sei=RYAN en-aut-mei=Joseph kn-aut-name=ƒ‰ƒCƒAƒ“ƒWƒ‡ƒZƒt kn-aut-sei=ƒ‰ƒCƒAƒ“ kn-aut-mei=ƒWƒ‡ƒZƒt aut-affil-num=4 ORCID= en-aut-name=UWAGAKITakeshi en-aut-sei=UWAGAKI en-aut-mei=Takeshi kn-aut-name=ãž• kn-aut-sei=ãž kn-aut-mei=• aut-affil-num=5 ORCID= en-aut-name=NAGAHARAMasato en-aut-sei=NAGAHARA en-aut-mei=Masato kn-aut-name=’·Œ´³l kn-aut-sei=’·Œ´ kn-aut-mei=³l aut-affil-num=6 ORCID= en-aut-name=YOSHIEYuta en-aut-sei=YOSHIE en-aut-mei=Yuta kn-aut-name=‹g]—Y‘¾ kn-aut-sei=‹g] kn-aut-mei=—Y‘¾ aut-affil-num=7 ORCID= en-aut-name=IKEHATAKei en-aut-sei=IKEHATA en-aut-mei=Kei kn-aut-name=’r’[Œc kn-aut-sei=’r’[ kn-aut-mei=Œc aut-affil-num=8 ORCID= en-aut-name=KIMURAOsamu en-aut-sei=KIMURA en-aut-mei=Osamu kn-aut-name=–Ø‘º— kn-aut-sei=–Ø‘º kn-aut-mei=— aut-affil-num=9 ORCID= en-aut-name=HATTORIRyoichi en-aut-sei=HATTORI en-aut-mei=Ryoichi kn-aut-name=•ž•”—ºˆê kn-aut-sei=•ž•” kn-aut-mei=—ºˆê aut-affil-num=10 ORCID= affil-num=1 en-affil=Kurashiki Museum of Natural History kn-affil= affil-num=2 en-affil=Okayama University, Department of Earth Sciences kn-affil= affil-num=3 en-affil=Okayama University, Department of Earth Sciences kn-affil= affil-num=4 en-affil=Okayama University, Research Institute for the Dynamics of Civilizations kn-affil= affil-num=5 en-affil=Okayama Prefectural Board of Education kn-affil= affil-num=6 en-affil=The Historical Study Group of Mining and Metallurgy of Japan kn-affil= affil-num=7 en-affil=Mitsui Mining & Smelting Co., Ltd. kn-affil= affil-num=8 en-affil=University of Tsukuba, Faculty of Life and Environmental Sciences kn-affil= affil-num=9 en-affil=Okayama University, Research Institute for the Dynamics of Civilizations kn-affil= affil-num=10 en-affil=Osaka University, Graduate School of Humanities kn-affil= en-keyword=Iron-smithing sites kn-keyword=Iron-smithing sites en-keyword=skarn deposits kn-keyword=skarn deposits en-keyword=mineral composition of ore kn-keyword=mineral composition of ore en-keyword=geochemical analysis kn-keyword=geochemical analysis END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue= article-no= start-page=1 end-page=18 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=An army post of the 17th Division of the Imperial Japanese Army as deciphered from an analysis of an old photograph kn-title=‹Œ“ú–{—¤ŒR‘æ\ŽµŽt’c’““Ô’n‘¢‰cŽžŒÃŽÊ^‚̉ð“Ç en-subtitle= kn-subtitle= en-abstract= kn-abstract=In 2022, an old photograph was discovered that was thought to be of an army post of the 17th Division of the Imperial Japanese Army, but unfortunately it had no textual record.

Quantitative evaluation of the thickness and water content of the stratum corneum is useful as a measure of skin barrier function in fields such as dermatology, nursing science, and cosmetics development. The stratum corneum is responsible for most of the skin barrier function, and this function has conventionally been evaluated using transepidermal water loss (TEWL). In this paper, we propose a new model for estimation of TEWL from measurements of the thickness of the stratum corneum and water content of the surface of the stratum corneum, and discuss the results of the measurements. By measuring the thickness and water content of the stratum corneum using confocal laser microscopy and confocal Raman spectroscopy, respectively, and examining the relationship of these variables with TEWL, we established a new potential model for estimating TEWL from these two variables. The correlation coefficient of the validation data was 0.886 and the root mean squared error was 8.18 points. These findings indicate the feasibility of qualitative evaluation of TEWL by measuring the thickness and water content of the stratum corneum. en-copyright= kn-copyright= en-aut-name=UeharaOsamu en-aut-sei=Uehara en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KusuharaToshimasa en-aut-sei=Kusuhara en-aut-mei=Toshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraTakao en-aut-sei=Nakamura en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Medical Engineering Laboratory, ALCARE Co., Ltd. kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=TEWL kn-keyword=TEWL en-keyword=stratum corneum thickness kn-keyword=stratum corneum thickness en-keyword=water content of stratum corneum kn-keyword=water content of stratum corneum END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=4 article-no= start-page=213 end-page=218 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=ƒÀ-catenin Binds to Gsk-3ƒÀ in Liquid-Liquid Phase Separation Compartment in HEK293 Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Liquid-liquid phase separation (LLPS) has emerged as a significant mechanism for cellular organization, impacting various biological processes, including Wnt/ƒÀ-catenin signaling. This study investigates the role of LLPS in the regulation of ƒÀ-catenin in HEK293 cells, particularly in response to Wnt3a signaling. Our findings demonstrate that ƒÀ-catenin is regulated by LLPS, forming spherical droplets indicative of this phenomenon. Fluorescence recovery after photobleaching (FRAP) assays revealed that these droplets exhibit reversible dynamics, further confirming their phase-separated nature. Importantly, treatment with Wnt3a led to an increase in ƒÀ-catenin levels, while simultaneously reducing the recovery of fluorescence intensity in FRAP experiments, suggesting that enhanced Wnt signaling may stimulate the release of ƒÀ-catenin from LLPS. Immunoprecipitation studies indicated that ƒÀ-catenin binds to glycogen synthase kinase 3ƒÀ (Gsk-3ƒÀ) within the LLPS state, highlighting a potential regulatory mechanism whereby LLPS facilitates the phosphorylation and subsequent degradation of ƒÀ-catenin. The addition of 1,6-hexanediol disrupted the ƒÀ-catenin/Gsk-3ƒÀ interaction, reinforcing the idea that LLPS plays a critical role in modulating these biochemical interactions. The findings presented in this study suggest that LLPS is not only crucial for the spatial organization of ƒÀ-catenin but also serves as a regulatory mechanism for its signaling functions in the Wnt pathway. Given the association of aberrant Wnt signaling with various diseases, including cancer and neurodegenerative disorders, understanding the role of LLPS in this context may provide new insights into therapeutic strategies targeting these pathological conditions. en-copyright= kn-copyright= en-aut-name=KatoMari en-aut-sei=Kato en-aut-mei=Mari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanaiAiri en-aut-sei=Tanai en-aut-mei=Airi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukuharaYoko en-aut-sei=Fukuhara en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZhengXinyu en-aut-sei=Zheng en-aut-mei=Xinyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SitosariHeriati en-aut-sei=Sitosari en-aut-mei=Heriati kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 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=8 ORCID= affil-num=1 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=The Center for Graduate Medical Education (Dental Division), Okayama University Hospital 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 Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=ƒÀ-catenin kn-keyword=ƒÀ-catenin en-keyword=Gsk-3ƒÀ kn-keyword=Gsk-3ƒÀ en-keyword=LLPS kn-keyword=LLPS en-keyword=Wnt kn-keyword=Wnt 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=20241214 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of aged microplastics on paddy soil properties and greenhouse gas emissions under laboratory aerobic conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Microplastics (MPs) formed after changes in chemical or physical properties may alter soil properties, which in turn may affect microbial activities and greenhouse gas (GHG) emissions. However, few studies have focused on the effects of aged MPs changes on soil properties and greenhouse gas emissions. Therefore, we aimed to investigate the impact of MPs with different aging times on soil GHG emissions and dissolved organic carbon (DOC). Low-density polyethylene (PE) and polylactic acid (PLA) were treated with ultraviolet (UV) irradiation for 0?2?weeks. Soil was incubated with PE or PLA 1% (w/w) concentration at 60% water holding capacity (WHC) for 35?days. Emissions of nitrous oxide (N2O) and carbon dioxide (CO2) were measured on days 0, 1, 3, 5, 7, 14, 21, 28, and 35. Results showed that CO2 and N2O emissions were higher (p? Conclusion: In this Japanese cohort, IVF conception was not associated with adverse long-term health or developmental outcomes. These findings provide reassurance about the safety of IVF, particularly in the context of single embryo transfer policies. Further research is needed to explore specific IVF protocols and subgroups. en-copyright= kn-copyright= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitsuiTakashi en-aut-sei=Mitsui en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KadowakiTomoka en-aut-sei=Kadowaki en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HirotaTomoya en-aut-sei=Hirota en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Psychiatry and Behavioral Sciences, UCSF Weill Institute for Neurosciences, University of California San Francisco kn-affil= affil-num=6 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=In vitro fertilization (IVF) kn-keyword=In vitro fertilization (IVF) en-keyword=Assisted reproductive technology (ART) kn-keyword=Assisted reproductive technology (ART) en-keyword=Long-term outcome kn-keyword=Long-term outcome en-keyword=Development kn-keyword=Development END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=1 article-no= start-page=46 end-page=60 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=Terpolymerization reactions of epoxides, CO2, and the third monomers toward sustainable CO2-based polymers with controllable chemical and physical properties en-subtitle= kn-subtitle= en-abstract= kn-abstract=Carbon dioxide (CO2) serves as a cheap, abundant, and renewable C1 building block for the synthesis of organic compounds and polymers. Selective and efficient CO2 fixation processes are still challenging because of the kinetic and thermodynamic stability of CO2. Among various CO2 fixation processes, the ring-opening copolymerization (ROCOP) of epoxides and CO2 gives aliphatic polycarbonates with high atom economy, although the chemical and physical properties of the resulting polycarbonates are not necessarily satisfactory. Introducing the third monomers into this ROCOP system provides new terpolymers, and the thermal, optical, mechanical or degradation properties can be added or tuned by incorporating new polymer backbones derived from the third monomers at the expense of the CO2 content. Here we review the terpolymerization reactions of epoxides, CO2, and the third monomers such as cyclic anhydrides, lactones, lactides, heteroallenes, and olefins. The development of catalysts and the control of the polymer structures are described together with the chemical and physical properties of the resulting polymers. en-copyright= kn-copyright= en-aut-name=NakaokaKoichi en-aut-sei=Nakaoka en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EmaTadashi en-aut-sei=Ema en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=‹à‘®ŽxŽŒ^ŒÅ‘ÌŽ_‰»•¨Œ`”R—¿“d’r‚Ì«”\•]‰¿‚ÉŠÖ‚·‚錤‹† en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=YODAMasakazu en-aut-sei=YODA en-aut-mei=Masakazu kn-aut-name=ˆË“c«˜a kn-aut-sei=ˆË“c kn-aut-mei=«˜a aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama university kn-affil=‰ªŽR‘åŠw‘åŠw‰@Ž©‘R‰ÈŠwŒ¤‹†‰È END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=ƒCƒbƒgƒŠƒAˆÀ’艻ƒWƒ‹ƒRƒjƒA“d‰ðŽ¿–Œ‚̒ቷ¬–Œ‹Zp‚ÉŠÖ‚·‚錤‹† en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MANABEKyohei en-aut-sei=MANABE en-aut-mei=Kyohei kn-aut-name=áÁ“ç‹•½ kn-aut-sei=áÁ“ç kn-aut-mei=‹•½ aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama university kn-affil=‰ªŽR‘åŠw‘åŠw‰@Ž©‘R‰ÈŠwŒ¤‹†‰È END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=ƒƒ{ƒbƒg‘€ì‚Ì‚½‚ß‚ÌŽ‹Šoî•ñˆ—‚ð—p‚¢‚½•s’èŒ`‚Ђà‚Ìó‘Ô”FŽ¯Žè–@ kn-title=Recognition Methodology of Deformable String State Using Visual Information Processing for Robotic Manipulation en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=WANGJUNXIANG en-aut-sei=WANG en-aut-mei=JUNXIANG kn-aut-name=‰¤rË kn-aut-sei=‰¤ kn-aut-mei=rË aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama university kn-affil=‰ªŽR‘åŠw‘åŠw‰@Ž©‘R‰ÈŠwŒ¤‹†‰È END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=ELiPSƒx[ƒX‚̈Æ•¶ƒ|ƒŠƒV[‘®«ƒx[ƒXˆÃ† kn-title=ELiPS-based Ciphertext-Policy Attribute-Based Encryption en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=LE HOANG ANH en-aut-sei=LE HOANG ANH en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama university kn-affil=‰ªŽR‘åŠw‘åŠw‰@Ž©‘R‰ÈŠwŒ¤‹†‰È END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=IoTƒAƒvƒŠƒP[ƒVƒ‡ƒ“EƒVƒXƒeƒ€‚Ì‚½‚ß‚Ì“‡ƒT[ƒoEƒvƒ‰ƒbƒgƒtƒH[ƒ€‚ÉŠÖ‚·‚錤‹† kn-title=A Study of Integrated Server Platform for IoT Application Systems en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=YOHANES YOHANIE FRIDELIN PANDUMAN en-aut-sei=YOHANES YOHANIE FRIDELIN PANDUMAN en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama university kn-affil=‰ªŽR‘åŠw‘åŠw‰@Ž©‘R‰ÈŠwŒ¤‹†‰È END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=ƒ†[ƒUPCƒRƒ“ƒsƒ…[ƒeƒBƒ“ƒOƒVƒXƒeƒ€‚É‚¨‚¯‚é‹ÏˆêƒWƒ‡ƒu‚̃[ƒJŠ„“–ƒAƒ‹ƒSƒŠƒYƒ€‚ÉŠÖ‚·‚錤‹† kn-title=A Study of Uniform Job Assignment Algorithms to Workers in User-PC Computing System en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=ZHOUXUDONG en-aut-sei=ZHOU en-aut-mei=XUDONG kn-aut-name=Žüˆ®“Œ kn-aut-sei=Žü kn-aut-mei=ˆ®“Œ aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama university kn-affil=‰ªŽR‘åŠw‘åŠw‰@Ž©‘R‰ÈŠwŒ¤‹†‰È END
