The development of novel, environmentally friendly, and cost-effective strategies for constructing C?N and C?O bonds is therefore of significant importance for the synthesis of these compounds. In recent years, carboxylic acids and their derivatives have emerged as attractive, inexpensive, non-toxic, and readily available synthetic building blocks, serving as promising alternatives to aryl halides. Growing evidence has demonstrated that decarboxylative amination and etherification of carboxylic acid derivatives offer a powerful approach for the synthesis of amines and ethers. These transformations proceed via three principal mechanistic pathways, each offering high atom economy. Specifically, carbanions (or organometallic species) generated through heterolytic decarboxylation can react with suitable electrophiles to form C?heteroatom bonds. In contrast, carbon-centred radicals produced through homolytic decarboxylation can couple with heteroatom-based reagents via radical recombination or oxidative trapping. Additionally, carbocations are typically formed via electrochemical oxidation of carboxylic acids: oxidative decarboxylation first yields a carbon radical, which is then further oxidized at the anode to generate a carbocation. This highly electrophilic intermediate can subsequently be intercepted by heteroatom nucleophiles to construct C?N or C?O bonds. This review highlights recent advances in the field, with a focus on transition metal catalysis, photoredox catalysis, and electrochemical methods for decarboxylative amination and etherification. en-copyright= kn-copyright= en-aut-name=YanWeidan en-aut-sei=Yan en-aut-mei=Weidan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TianTian en-aut-sei=Tian en-aut-mei=Tian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishiharaYasushi en-aut-sei=Nishihara en-aut-mei=Yasushi 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=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science (RIIS), Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e00678 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250623 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Alkoxy‐Substituted Anthrabis(Thiadiazole)‐Terthiophene Copolymers for Organic Photovoltaics: A Unique Wavy Backbone Enhances Aggregation, Molecular Order, and Device Efficiency en-subtitle= kn-subtitle= en-abstract= kn-abstract=Two polymer donors, PATz3T-o6BO and PATz3T-o6HD, incorporating alkoxy-substituted anthra[1,2-c:5,6-c′]bis([1,2,5]thiadiazole), were strategically designed and synthesized.

While significant progress has been made in the development of highly oxidizing catalysts, such as acridinium catalysts, there remains a notable shortage of strongly reducing organophotoredox catalysts. Phenothiazines are widely used as photoredox catalysts owing to their unique redox potentials, particularly their low excited-state oxidation potentials (Eox* = ?1.35 V to ?3.51 V vs. SCE). Thus, they can be applied to a variety of photoredox reactions with oxidative-quenching cycles, and effectively reduce various organic molecules, such as aryl and alkyl halides, alkenes, malonyl peroxides, cobalt complexes, and redox-active esters. Due to their unique properties, this review focuses on the recent advances in phenothiazine organophotoredox catalysis. en-copyright= kn-copyright= en-aut-name=TanakaKenta en-aut-sei=Tanaka en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakamuraHiroyoshi en-aut-sei=Takamura en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary 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=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Phenothiazine kn-keyword=Phenothiazine en-keyword=Photoredox catalysis kn-keyword=Photoredox catalysis en-keyword=Visible light kn-keyword=Visible light en-keyword=Radical kn-keyword=Radical END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=10819 end-page= 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=A high-protein diet-responsive gut hormone regulates behavioral and metabolic optimization in Drosophila melanogaster en-subtitle= kn-subtitle= en-abstract= kn-abstract=Protein is essential for all living organisms; however, excessive protein intake can have adverse effects, such as hyperammonemia. Although mechanisms responding to protein deficiency are well-studied, there is a significant gap in our understanding of how organisms adaptively suppress excessive protein intake. In the present study, utilizing the fruit fly, Drosophila melanogaster, we discover that the peptide hormone CCHamide1 (CCHa1), secreted by enteroendocrine cells in response to a high-protein diet (HPD), is vital for suppressing overconsumption of protein. Gut-derived CCHa1 is received by a small subset of enteric neurons that produce short neuropeptide F, thereby modulating protein-specific satiety. Importantly, impairment of the CCHa1-mediated gut-enteric neuronal axis results in ammonia accumulation and a shortened lifespan under HPD conditions. Collectively, our findings unravel the crosstalk of gut hormone and neuronal pathways that orchestrate physiological responses to prevent and adapt to dietary protein overload. en-copyright= kn-copyright= en-aut-name=YoshinariYuto en-aut-sei=Yoshinari en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimuraTakashi en-aut-sei=Nishimura en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=KondoShu en-aut-sei=Kondo en-aut-mei=Shu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanimotoHiromu en-aut-sei=Tanimoto en-aut-mei=Hiromu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KobayashiTomoe en-aut-sei=Kobayashi en-aut-mei=Tomoe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=NiwaRyusuke en-aut-sei=Niwa en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Metabolic Regulation and Genetics, Institute for Molecular and Cellular Regulation, Gunma University kn-affil= affil-num=2 en-affil=Metabolic Regulation and Genetics, Institute for Molecular and Cellular Regulation, Gunma 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=Department of Biological Science and Technology, Faculty of Advanced Engineering, Tokyo University of Science kn-affil= affil-num=5 en-affil=Graduate School of Life Sciences, Tohoku University kn-affil= affil-num=6 en-affil=Division of Molecular Genetics, Shigei Medical Research Institute kn-affil= affil-num=7 en-affil=Division of Molecular Genetics, Shigei Medical Research Institute kn-affil= affil-num=8 en-affil=Life Science Center for Survival Dynamics, Tsukuba Advanced Research Alliance (TARA), University of Tsukuba kn-affil= END start-ver=1.4 cd-journal=joma no-vol=35 cd-vols= no-issue=12 article-no= start-page=2916 end-page=2926.e3 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=Oxytocin facilitates human touch-induced play behavior in rats en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pleasant touch sensations play a fundamental role in social bonding, yet the neural mechanisms underlying affinity-like behaviors remain poorly understood. Here, we demonstrate that juvenile-adolescent rats, which naturally engage in social play with peers characterized by rough-and-tumble interactions and 50 kHz ultrasonic vocalizations indicating pleasant sensations, develop a strong affinity for human hands through similar playful contact achieved by repeated tickling with human hands. Using this rat with tickling-induced high affinity for human hands, we discovered that repeated tickling mimicking rough-and-tumble play led to increased oxytocin receptor (OTR) expression in the ventrolateral part of the ventromedial hypothalamus (VMHvl). Inhibition of oxytocin signaling in the VMHvl reduced affinity-like behaviors from rats to human hands. These findings suggest that OTR neurons in VMHvl play an important role in the increase in affinity for human hands induced by pleasant touch sensation with human touch-induced play behavior. Based on retrograde and anterograde tracing studies examining the supraoptic nucleus (SON) and the paraventricular nucleus (PVN) as primary sources of oxytocin, we demonstrate that a subset of oxytocin fibers in the VMHvl originate from the SON, suggesting that affinity-like behavior from rats to human hands may be controlled by oxytocin signaling from magnocellular neurons. Together, this work advances our understanding of how oxytocin shapes social behavior and may inform the development of therapeutic strategies to promote positive social interactions. en-copyright= kn-copyright= en-aut-name=HayashiHimeka en-aut-sei=Hayashi en-aut-mei=Himeka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TateishiSayaka en-aut-sei=Tateishi en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InutsukaAyumu en-aut-sei=Inutsuka en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaejimaSho en-aut-sei=Maejima en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HagiwaraDaisuke en-aut-sei=Hagiwara en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakumaYasuo en-aut-sei=Sakuma en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OnakaTatsushi en-aut-sei=Onaka en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=GrinevichValery en-aut-sei=Grinevich en-aut-mei=Valery kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SakamotoHirotaka en-aut-sei=Sakamoto en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Biology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University, kn-affil= affil-num=2 en-affil=Ushimado Marine Institute (UMI), Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Division of Brain and Neurophysiology, Department of Physiology, Jichi Medical University kn-affil= affil-num=4 en-affil=Ushimado Marine Institute (UMI), Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Department of Neuropeptide Research in Psychiatry, Central Institute of Mental Health, German Center for Psychiatry (DZPG), Medical Faculty Mannheim, University of Heidelberg kn-affil= affil-num=6 en-affil=Department of Anatomy and Neurobiology, Graduate School of Medical Sciences, Nippon Medical School kn-affil= affil-num=7 en-affil=Division of Brain and Neurophysiology, Department of Physiology, Jichi Medical University kn-affil= affil-num=8 en-affil=Department of Neuropeptide Research in Psychiatry, Central Institute of Mental Health, German Center for Psychiatry (DZPG), Medical Faculty Mannheim, University of Heidelberg kn-affil= affil-num=9 en-affil=Department of Biology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University, kn-affil= en-keyword=tickling kn-keyword=tickling en-keyword=oxytocin kn-keyword=oxytocin en-keyword=oxytocin receptor kn-keyword=oxytocin receptor en-keyword=ventrolateral part of the ventromedial hypothalamus kn-keyword=ventrolateral part of the ventromedial hypothalamus en-keyword=affinity-like behaviors kn-keyword=affinity-like behaviors 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 π-bonds as 2π components, represented by dienophiles in Diels?Alder reactions, has been well studied, “the strained diene (4π component) approach” 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=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=ボールエンドミルの突き出し長さに応じた切削条件補正システムの開発 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=児玉紘幸 kn-aut-sei=児玉 kn-aut-mei=紘幸 aut-affil-num=1 ORCID= en-aut-name=MORIYAYuki en-aut-sei=MORIYA en-aut-mei=Yuki kn-aut-name=守屋祐輝 kn-aut-sei=守屋 kn-aut-mei=祐輝 aut-affil-num=2 ORCID= en-aut-name=MORIMOTOTatsuo en-aut-sei=MORIMOTO en-aut-mei=Tatsuo kn-aut-name=盛元達雄 kn-aut-sei=盛元 kn-aut-mei=達雄 aut-affil-num=3 ORCID= en-aut-name=OHASHIKazuhito en-aut-sei=OHASHI en-aut-mei=Kazuhito kn-aut-name=大橋一仁 kn-aut-sei=大橋 kn-aut-mei=一仁 aut-affil-num=4 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学 学術研究院環境生命自然科学学域 affil-num=2 en-affil=Graduate school of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学 大学院環境生命自然科学研究科 affil-num=3 en-affil=Graduate school of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学 大学院環境生命自然科学研究科 affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学 学術研究院環境生命自然科学学域 en-keyword=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= 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= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250623 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Transformation of α,β-Unsaturated Aldehydes with a Small Amount of Electricity: Cyanosilylation, Isomerization, and Nucleophilic Addition en-subtitle= kn-subtitle= en-abstract= kn-abstract=An electrochemical method was developed to convert α,β-unsaturated aldehydes into carboxylic acid derivatives via cyanosilylation, isomerization, and nucleophilic addition.

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= cd-vols= no-issue= article-no= start-page= 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=持続可能な発展に向けた携帯電話リサイクルの推進:消費者行動分析、デジタルトランスフォーメーション戦略、および革新的インセンティブメカニズムの統合 kn-title=Optimizing cell phone recycling for sustainable development: Integrating consumer behavior analysis, digital transformation strategies, and innovative incentive mechanisms en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=DUYuxin en-aut-sei=DU en-aut-mei=Yuxin kn-aut-name=杜余? kn-aut-sei=杜 kn-aut-mei=余? aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=稲わら施用水田土壌からのCH4およびCO2 排出抑制に向けた底質微生物燃料電池の開発 kn-title=Development of sediment microbial fuel cells to reduce CH4 and CO2 emissions from straw-amended paddy soil en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=ADHENA TESFAU BEKELE en-aut-sei=ADHENA TESFAU BEKELE 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 Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=マイクロ流体ペーパー分析デバイスによる窒素化合物の現場環境分析法の開発 kn-title=Development of on-site environmental analytical methods for nitrogen compounds using microfluidic paper-based analytical devices en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=UMEDA (ISOYAMA)Mika en-aut-sei=UMEDA (ISOYAMA) en-aut-mei=Mika kn-aut-name=梅田(礒山)美華 kn-aut-sei=梅田(礒山) kn-aut-mei=美華 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama university kn-affil=岡山大学大学院自然科学研究科 END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=3 article-no= start-page=147 end-page=155 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=Immunometabolic Regulation of Innate Immunity in Systemic Lupus Erythematosus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pathogens or their components can induce long-lasting changes in the behavior of innate immune cells, a process analogous to “training” for future threats or environmental adaptation. However, such training can sometimes have unintended consequences, such as the development of autoimmunity. Systemic lupus erythematosus (SLE) is a chronic and heterogeneous autoimmune disease characterized by the production of autoantibodies and progressive organ damage. Innate immunity plays a central role in its pathogenesis, contributing through impaired clearance of apoptotic cells, excessive type I interferon production, and dysregulated formation of neutrophil extracellular traps. Recent studies have revealed that metabolites and nucleic acids derived from mitochondria, a crucial energy production site, directly regulate type I interferon and anti-inflammatory cytokine production. These insights have fueled interest in targeting metabolic pathways as a novel therapeutic approach for SLE, offering promise for improving long-term patient outcomes. en-copyright= kn-copyright= en-aut-name=WatanabeHaruki en-aut-sei=Watanabe en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoYoshinori en-aut-sei=Matsumoto en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=systemic lupus erythematosus kn-keyword=systemic lupus erythematosus en-keyword=interferon kn-keyword=interferon en-keyword=tricarboxylic acid cycle kn-keyword=tricarboxylic acid cycle en-keyword=innate immune memory kn-keyword=innate immune memory en-keyword=trained immunity kn-keyword=trained immunity 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=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=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=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=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=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.

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=15 cd-vols= no-issue= article-no= start-page=357 end-page=371 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Proposals for Supporting Children’s Adaptation in School Mergers and Closures kn-title=学校統廃合における児童の適応支援策の提言 en-subtitle= kn-subtitle= en-abstract=The purpose of this study is to examine the impact of school mergers and closures on children through a literature review and field survey and to propose strategies for supporting children's adaptation to the resulting environmental transitions. First, a literature review on school mergers and closures indicated that such experiences could influence children's later interpersonal relationships and increase stress responses. However, research on the impact of school mergers and closures on children remains limited, with insufficient understanding of their psychological effects on children. Next, interviews conducted as part of a field survey revealed that school mergers and closures could be significant sources of stress for children. Based on these findings, we recommends multi-level support measures targeting individuals, classes, grades, and entire schools, primarily through special activities, to help mitigate the impact of these transitions on children. kn-abstract=本研究の目的は,学校統廃合に係る文献検索および実態調査を通して,学校統廃合という環境移行が児童に与える影響について検討し,学校統廃合がもたらす環境移行に対する児童の適応支援策について提言することである。まず,学校統廃合に係る文献検索を行った結果,学校統廃合の経験が児童生徒のその後の人間関係形成やストレス反応の増加に影響を与えている可能性が示された。しかし,学校統廃合が児童に与える影響に関する研究は非常に少なく,統廃合の経験が児童に与える心理的影響については十分に解明されていないことがわかった。次に,実態調査として行ったインタビューにおいて,学校統廃合が児童にとって大きなストレス要因となる可能性があることがわかった。これらの現状を踏まえて,学校統廃合が児童に与える影響を和らげるため,特別活動を中心として,個人・学級・学年・学校レベルでの具体的な取組を提案した。 en-copyright= kn-copyright= en-aut-name=IKEDAYuka en-aut-sei=IKEDA en-aut-mei=Yuka kn-aut-name=池田?加 kn-aut-sei=池田 kn-aut-mei=?加 aut-affil-num=1 ORCID= en-aut-name=IZUMITsuguyuki en-aut-sei=IZUMI en-aut-mei=Tsuguyuki kn-aut-name=伊住継行 kn-aut-sei=伊住 kn-aut-mei=継行 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education (Professional Degree Corse), Okayama University kn-affil=岡山大学大学院教育学研究科大学院生 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=学校統廃合 (School Consolidation) kn-keyword=学校統廃合 (School Consolidation) en-keyword=児童 (Children) kn-keyword=児童 (Children) en-keyword=人間関係形成 (Relationship Building) kn-keyword=人間関係形成 (Relationship Building) en-keyword=ストレス (Stress) kn-keyword=ストレス (Stress) en-keyword=特別活動 (Special Activities) kn-keyword=特別活動 (Special Activities) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=281 end-page=295 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Development Support a Child with Autism to Acquisition of Intersubjective Communication: Through the Environmental Setting of Play with Shared Positive Emotions kn-title=ASD 児における相互伝達行為の獲得を目指した遊びを中心としたコミュニケーション指導 ポジティブな情動の共有を生み出す遊びの環境設定を通して en-subtitle= kn-subtitle= en-abstract=In this study, a play-based instruction was used to promote the acquisition of intersubjective communication in a special needs school for students with intellectual disabilities.

It was suggested that four aspects of the play environment may have promoted the acquisition of intersubjective communication: 1) attractive toys, 2) play with the teacher through attractive toys, 3) intervention according to the developmental process of the target children's play, and 4) empathic involvement to encourage the affective sharing. kn-abstract= 自閉スペクトラム症児は,相互伝達行為の獲得に遅れがあることが指摘されている。本研究では,自閉スペクトラム症の診断のある知的障害特別支援学校小学部1年生男児を対象に,相互伝達行為の獲得を目指して,遊びを中心とした指導を行った。その結果,対象児の遊びが「感覚運動的遊び」「機能的遊び」から「象徴的遊び」「社会的遊び」へと移行するに伴い,相互伝達行為が見られるようになった。また,教師による働き掛けへの応答も見られるようになり,ポジティブな情動の共有が生み出されやすい遊びの環境設定が,相互伝達行為の獲得において効果的であったことが示唆された。遊び環境については,1)魅力的な玩具,2)魅力的な玩具を介した教師との遊び,3)対象児の遊びの発達段階に応じた介入,4)情動の共有を促す共感的関わりの4点が相互伝達行為の獲得を促した可能性が考えられた。 en-copyright= kn-copyright= en-aut-name=KAKUHARAKeisuke en-aut-sei=KAKUHARA en-aut-mei=Keisuke kn-aut-name=角原佳介 kn-aut-sei=角原 kn-aut-mei=佳介 aut-affil-num=1 ORCID= en-aut-name=BANMarina en-aut-sei=BAN en-aut-mei=Marina kn-aut-name=伴真里奈 kn-aut-sei=伴 kn-aut-mei=真里奈 aut-affil-num=2 ORCID= en-aut-name=TANJITakayuki en-aut-sei=TANJI en-aut-mei=Takayuki kn-aut-name=丹治敬之 kn-aut-sei=丹治 kn-aut-mei=敬之 aut-affil-num=3 ORCID= affil-num=1 en-affil=Tobi Special School kn-affil=岡山県立東備支援学校 affil-num=2 en-affil=Special School Affiliated with the Faculty of Education at Okayama University kn-affil=岡山大学教育学部附属特別支援学校 affil-num=3 en-affil=Institute of Human Sciences, University of Tsukuba kn-affil=筑波大学人間系 en-keyword=自閉スペクトラム症 (a Child with Autism) kn-keyword=自閉スペクトラム症 (a Child with Autism) en-keyword=相互伝達行為 (Intersubjective Communication) kn-keyword=相互伝達行為 (Intersubjective Communication) en-keyword=情動の共有 (effective sharing) kn-keyword=情動の共有 (effective sharing) en-keyword=遊びの環境設定 (Setting of Play) kn-keyword=遊びの環境設定 (Setting of Play) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=8502 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Age-specific assessment of initial hemoglobin levels and shock index for predicting life-saving interventions in pediatric blunt liver and spleen injuries en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to evaluate the effectiveness of combining initial hemoglobin levels with the shock index for predicting the need for life-saving interventions (LSI) in pediatric patients with blunt liver and spleen injuries (BLSI), specifically tailored to different age groups. This was a multicenter retrospective cohort study of pediatric patients with BLSI in Japan. The area under the receiver operating characteristic curve (AUROC) were used to assess predictive accuracy. The study included 1,370 patients. LSI was required in 59 of 247 (23.9%) aged 1 to 6 years, 100 of 402 (24.9%) aged 7 to 12 years, and 125 of 297 (42.1%) patients aged 13 to 16 years. Within each specific age group, the predictability was categorized as fair and appeared higher than that of the entire cohort or when using either parameter alone. Notably, in the 1 to 6-year age group, the combined values showed the highest predictability, which was statistically superior to the shock index alone (AUROC of 0.770 vs. 0.671, P = 0.025). Tailoring initial hemoglobin levels and shock index to specific age groups enhances predictability of LSI in pediatric BLSI, showing a fair level of predictive accuracy. en-copyright= kn-copyright= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IidaAtsuyoshi en-aut-sei=Iida en-aut-mei=Atsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatsuraMorihiro en-aut-sei=Katsura en-aut-mei=Morihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KondoYutaka en-aut-sei=Kondo en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YasudaHideto en-aut-sei=Yasuda en-aut-mei=Hideto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KushimotoShigeki en-aut-sei=Kushimoto en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=SHIPPs Study Group en-aut-sei=SHIPPs Study Group en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Surgery, Okinawa Chubu Hospital kn-affil= affil-num=7 en-affil=Department of Emergency and Critical Care Medicine, Juntendo University Urayasu Hospital kn-affil= affil-num=8 en-affil=Department of Emergency and Critical Care Medicine, Jichi Medical University Saitama Medical Center kn-affil= affil-num=9 en-affil=Division of Emergency and Critical Care Medicine, Tohoku University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=13 en-affil= kn-affil= en-keyword=Abdominal injuries kn-keyword=Abdominal injuries en-keyword=Blood transfusions kn-keyword=Blood transfusions en-keyword=Hemoglobin kn-keyword=Hemoglobin en-keyword=Hemostasis kn-keyword=Hemostasis en-keyword=Shock index kn-keyword=Shock index 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=15 cd-vols= no-issue=2 article-no= start-page=235 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=Distinct Infection Mechanisms of Rhizoctonia solani AG-1 IA and AG-4 HG-I+II in Brachypodium distachyon and Barley en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rhizoctonia solani is a basidiomycete phytopathogenic fungus that causes rapid necrosis in a wide range of crop species, leading to substantial agricultural losses worldwide. 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= 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=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=236 cd-vols= no-issue= article-no= start-page=74 end-page=81 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=Characteristics of porcine oocyte-cumulus complexes derived from various sizes of antral follicles and classified by brilliant cresyl blue staining, and developmental competence of the oocytes en-subtitle= kn-subtitle= en-abstract= kn-abstract=The present study sought to determine the characteristics of porcine oocyte-cumulus complexes (OCCs) derived from very small and small antral follicles (with less than 1 mm and 1?3 mm in diameter, respectively; VSF and SF) in comparison with controls from medium ones (with 3?6 mm in diameter; MF). Additionally, the present study examined the utility of brilliant cresyl blue (BCB) staining for assessing these OCCs. The incidence of BCB- oocytes in VSF- and SF-derived OCCs was higher than that in MF-derived OCCs. Although the meiotic and developmental competences of BCB+ oocytes from MF were superior to those from VSF and SF, blastocysts were successfully obtained from BCB+ oocytes even derived from VSF. The mean numbers of both total and viable cumulus cells surrounding an oocyte were significantly affected not only by the origin of the OCCs, but also by the BCB status of the oocytes (largest in MF-derived OCCs containing BCB+ oocytes). Although the outer and inner diameters of zona pellucida were affected by the origin of OCCs and the BCB status of oocytes (largest in MF-derived oocytes), the ooplasmic diameter of BCB+ oocytes did not differ among those derived from VSF, SF, and MF. Regardless of the BCB status, the transcriptional levels of G6PD and TKT in cumulus cells decreased during follicular development from VSF to MF, whereas the RPIA mRNA level in cumulus cells of MF-derived BCB+ OCCs was lower than in the others. These results underscore the utility of BCB staining for selecting MF-, SF-, and even VSF-derived OCCs containing oocytes with relatively higher meiotic and developmental competences, as well as the importance of having a sufficient number of healthy cumulus cells expressing genes related to the pentose phosphate pathway at lower levels. en-copyright= kn-copyright= en-aut-name=VanPhong Ngoc en-aut-sei=Van en-aut-mei=Phong Ngoc kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DoSon Quang en-aut-sei=Do en-aut-mei=Son Quang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FonsekaWanniarachchige Tharindu Lakshitha en-aut-sei=Fonseka en-aut-mei=Wanniarachchige Tharindu Lakshitha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WakaiTakuya en-aut-sei=Wakai en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FunahashiHiroaki en-aut-sei=Funahashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= 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.

This study aimed to investigate these effects using an outcome-wide approach in a Japanese context, where perinatal mortality rates are among the world's lowest. We analyzed data from 2,114 children in a nationwide Japanese birth cohort, linking the 21st Century Longitudinal Survey of Newborns with the Perinatal Research Network database. We examined associations between CD and various health and developmental outcomes up to 9 years of age, including hospitalizations, obesity, and developmental milestones. After adjusting for potential confounders, CD was not significantly associated with most outcomes, including all-cause hospitalization (adjusted risk ratio 1.25, 95% CI 0.997-1.56), obesity at 5.5 and 9 years, and various developmental milestones. Subgroup analyses for multiple births and preterm infants showed some differences in point estimates, but were limited by small sample sizes. CD was not significantly associated with adverse long-term child health or developmental outcomes in this Japanese cohort. These findings provide reassurance regarding CD safety when medically indicated in advanced perinatal care settings. Further research with larger samples and longer follow-up is needed, especially for specific 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=TamaiKei en-aut-sei=Tamai en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HirotaTomoya en-aut-sei=Hirota en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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=Division of Neonatology, NHO Okayama Medical Center kn-affil= affil-num=4 en-affil=Department of Psychiatry and Behavioral Sciences, UCSF Weill Institute for Neurosciences, University of California San Francisco kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Cesarean delivery kn-keyword=Cesarean delivery en-keyword=Delivery methods kn-keyword=Delivery methods en-keyword=Long-term outcome kn-keyword=Long-term outcome en-keyword=Child development kn-keyword=Child development en-keyword=Outcome-wide approach kn-keyword=Outcome-wide approach END start-ver=1.4 cd-journal=joma no-vol=114 cd-vols= no-issue= article-no= start-page=21 end-page=25 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=Elucidation of plant-bacterial pathogen interactions for the control of bacterial blight on cruciferous crops kn-title=アブラナ科植物黒斑細菌病の防除に向けた植物−病原細菌の相互作用の解明 en-subtitle= kn-subtitle= en-abstract= kn-abstract= Pseudomonas cannabina pv. alisalensis (Pcal), the causative agent of bacterial blight on cruciferous crops, is an economically important pathogen worldwide. We have conducted several studies on the interactions between plants and pathogenic bacteria to develop effective control strategies for this disease. Using forward and reverse genetics, we identified several virulence factors, including the type III secretion system, membrane transporters, transcriptional factors, and amino acid metabolism. Additionally, we emphasized the role of coronatine, a toxin produced by Pcal, which promotes stomatal reopening and suppresses salicylic acid accumulation in plants. We also examined plant defense mechanisms activated by one of the plant defense activators, acibenzolar-S-methyl (ASM). ASM enhanced stomatal-based defense, resulting in reduction of bacterial entry and disease development. Moreover, we explored innovative control strategies for bacterial disease and demonstrated that amino acids and cellulose nanofiber are efficient and environmentally friendly control strategies. These studies advance our understanding of plant-pathogen dynamics and offer promising, sustainable approaches for managing bacterial blight disease in cruciferous crops. en-copyright= kn-copyright= en-aut-name=SakataNanami en-aut-sei=Sakata en-aut-mei=Nanami kn-aut-name=坂田七海 kn-aut-sei=坂田 kn-aut-mei=七海 aut-affil-num=1 ORCID= affil-num=1 en-affil=Course of Applied Plant Science kn-affil=応用植物科学コース en-keyword=Plant pathogenic bacteria kn-keyword=Plant pathogenic bacteria en-keyword=Pseudomonas kn-keyword=Pseudomonas en-keyword=Cruciferous kn-keyword=Cruciferous en-keyword=Plant protection kn-keyword=Plant protection en-keyword=Stomata kn-keyword=Stomata 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= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The perception of plastic waste and composition of boathouse waste in floating villages on Tonl? Sap Lake, Cambodia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Villagers living on Tonl? Sap (TS) Lake have low incomes and no access to basic public services, such as waste management, domestic water, electricity, and health care. Knowledge of the villagers’ perceptions and the composition of the waste from their boathouses will contribute to constructing a waste collection system with community participation within the framework of waste prevention and reduction. This study surveyed residents living in boathouses in four floating villages on TS Lake, Cambodia, regarding their perceptions and boathouse waste composition to assess the status of plastic waste and the villagers’ environmental awareness and their willingness to participate in waste collection. The household waste survey sought to clarify the amount of plastic waste and other recyclable waste discharged from floating houses. The perception survey revealed that in the wet season, 36% of respondents disposed of plastic waste by open burning/dumping and 40% by discharge into TS Lake; in the dry season, 76% disposed of waste by open burning/dumping, and only 4% discharged waste into TS Lake. An analysis of the boathouse plastic waste composition showed that residents of the floating villages generated 40.21 g plastic waste/day/capita, which was much lower than 340 g/day/capita in the USA, 120 g/day/capita in China, and even 70 g/day/capita in Cambodian on average, but higher than the 10 g/day/capita in India. This study proposes a novel and valuable framework to estimate and determine the level of awareness of people in floating villages related to plastic pollution effects and waste components from boathouses. At the same time, the research results provide an essential scientific basis to be able to develop an effective waste collection system in the area of TS Lake. The proposed framework of this study will help the policy decision-makers in the TS Lake area and those in similar geographical regions facing similar problems. en-copyright= kn-copyright= en-aut-name=Habuer en-aut-sei=Habuer en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiwaraTakeshi en-aut-sei=Fujiwara en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=VinSpoann en-aut-sei=Vin en-aut-mei=Spoann kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChandaraPhat en-aut-sei=Chandara en-aut-mei=Phat kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsukijiMakoto en-aut-sei=Tsukiji en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Environmental Management Course, Architecture, Civil Engineering and Environmental Management Program, School of Engineering, Okayama University kn-affil= affil-num=2 en-affil=Environmental Management Course, Architecture, Civil Engineering and Environmental Management Program, School of Engineering, Okayama University kn-affil= affil-num=3 en-affil=Department of Economic Development, Faculty of Development Studies, Royal University of Phnom Penh kn-affil= affil-num=4 en-affil=Department of Natural Resource Management and Development, Faculty of Development Studies, Royal University of Phnom Penh kn-affil= affil-num=5 en-affil=Environmental Management Course, Architecture, Civil Engineering and Environmental Management Program, School of Engineering, Okayama University kn-affil= en-keyword=Boathouse waste composition kn-keyword=Boathouse waste composition en-keyword=Cambodia kn-keyword=Cambodia en-keyword=Floating villages kn-keyword=Floating villages en-keyword=Perception survey kn-keyword=Perception survey en-keyword=Plastic waste kn-keyword=Plastic waste END start-ver=1.4 cd-journal=joma no-vol=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 feather’s 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 PBCF’s 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=21 cd-vols= no-issue=1 article-no= start-page=4 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250116 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Maternal smoking during infancy increases the risk of allergic diseases in children: a nationwide longitudinal survey in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background The incidence of allergic diseases has been increasing in Japan. In particular, a serious decline in the age of onset of allergic rhinitis has been observed. Passive smoking from parental smoking has a significant impact on children’s health; however, it is difficult to restrict smoking in the home. While various studies have previously reported on the relationship between passive smoking and the development of allergic diseases in children. However, there have been no reports on passive smoking and allergic diseases on a national scale.
Methods Using Japanese national longitudinal survey data (n?=?38,444) for newborns born between May 10 and 24, 2010, we assessed parental smoking habits when their children were 6 months old and investigated the association with the development of allergic diseases until the age of 5.5 years. The risk ratios and 95% confidence intervals for the development of different allergic diseases were analyzed after adjusting for potential confounders using Poisson regression with a robust error variance.
Results The risk ratio for developing allergic rhinitis/allergic conjunctivitis (AR/AC) in children was significantly higher in the maternal smoking groups (?≦?10 cigarettes/day; RR 1.15, 95% CI 1.02?1.30; ≧11 cigarettes/day; RR 1.16, 95% CI 0.93?1.44). Furthermore, associations were found between the maternal smoking group in the presence of paternal smoking and the risk of developing bronchial asthma (?≦?10, RR 1.33 95% CI 1.17?1.52; ≧11, RR 1.71 95% CI 1.38?2.1), food allergy (?≦?10, RR 1.36 95% CI 1.12?1.63; ≧11, RR 1.25 95% CI 0.84?1.86), atopic dermatitis (?≦?10, RR 1.42 95% CI 1.22?1.66; ≧11, RR 1.6 95% CI 1.2?2.13), and AR/AC (?≦?10, RR 1.21 95% CI 1.07?1.36; ≧11, RR 1.35 95% CI 1.09?1.67).
Conclusions Maternal smoking during infancy increases the risk of developing AR/AC in children. Considering paternal smoking, maternal smoking further increased the risk of developing allergic diseases in children, suggesting that reducing parental smoking at home may reduce the risk of developing allergic diseases in children. en-copyright= kn-copyright= en-aut-name=ShigeharaKenji en-aut-sei=Shigehara en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsugeMitsuru en-aut-sei=Tsuge en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UdaKazuhiro en-aut-sei=Uda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SaitoYukie en-aut-sei=Saito en-aut-mei=Yukie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YashiroMasato en-aut-sei=Yashiro en-aut-mei=Masato 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= en-aut-name=IkedaMasanori en-aut-sei=Ikeda en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pediatric Acute Diseases, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Allergic rhinitis kn-keyword=Allergic rhinitis en-keyword=Bronchial asthma kn-keyword=Bronchial asthma en-keyword=Atopic dermatitis kn-keyword=Atopic dermatitis en-keyword=National cohort study kn-keyword=National cohort study en-keyword=Passive smoking kn-keyword=Passive smoking END start-ver=1.4 cd-journal=joma no-vol=126 cd-vols= no-issue=1 article-no= start-page=012901 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250102 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dynamic domain motion enhancing electro-optic performance in ferroelectric films en-subtitle= kn-subtitle= en-abstract= kn-abstract=With the rapid advancement of information technology, there is a pressing need to develop ultracompact and energy-efficient thin-film-based electro-optic (EO) devices. A high EO coefficient in ferroelectric materials is crucial. However, substrate clamping can positively or negatively influence various physical properties, including the EO response of these films, thus complicating the development of next-generation thin-film-based devices. This study demonstrates that reversible dynamic domain motion, achieved through substrate clamping, significantly enhances the EO coefficient in epitaxial ferroelectric rhombohedral Pb(Zr, Ti)O3 thin films, where the (111) and (? 111?) domains coexist with distinct optical axes. In principle, this approach can be applied to different film-substrate systems, thereby contributing to the advancement of sophisticated EO devices based on ferroelectrics. en-copyright= kn-copyright= en-aut-name=KondoShinya en-aut-sei=Kondo en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkamotoKazuki en-aut-sei=Okamoto en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakataOsami en-aut-sei=Sakata en-aut-mei=Osami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TeranishiTakashi en-aut-sei=Teranishi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KishimotoAkira en-aut-sei=Kishimoto en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NagasakiTakanori en-aut-sei=Nagasaki en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamadaTomoaki en-aut-sei=Yamada en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Energy Engineering, Nagoya University kn-affil= affil-num=3 en-affil=Japan Synchrotron Radiation Research Institute (JASRI) kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Department of Energy Engineering, Nagoya University kn-affil= affil-num=7 en-affil=Department of Energy Engineering, Nagoya University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=52 article-no= start-page=35202 end-page=35213 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241216 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bright Quantum-Grade Fluorescent Nanodiamonds en-subtitle= kn-subtitle= en-abstract= kn-abstract=Optically accessible spin-active nanomaterials are promising as quantum nanosensors for probing biological samples. However, achieving bioimaging-level brightness and high-quality spin properties for these materials is challenging and hinders their application in quantum biosensing. Here, we demonstrate bright fluorescent nanodiamonds (NDs) containing 0.6?1.3-ppm negatively charged nitrogen-vacancy (NV) centers by spin-environment engineering via enriching spin-less 12C-carbon isotopes and reducing substitutional nitrogen spin impurities. The NDs, readily introduced into cultured cells, exhibited improved optically detected magnetic resonance (ODMR) spectra; peak splitting (E) was reduced by 2?3 MHz, and microwave excitation power required was 20 times lower to achieve a 3% ODMR contrast, comparable to that of conventional type-Ib NDs. They show average spin-relaxation times of T1 = 0.68 ms and T2 = 3.2 μs (1.6 ms and 5.4 μs maximum) that were 5- and 11-fold longer than those of type-Ib, respectively. Additionally, the extended T2 relaxation times of these NDs enable shot-noise-limited temperature measurements with a sensitivity of approximately 0.28K/√Hz. The combination of bulk-like NV spin properties and enhanced fluorescence significantly improves the sensitivity of ND-based quantum sensors for biological applications. en-copyright= kn-copyright= en-aut-name=OshimiKeisuke en-aut-sei=Oshimi en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshiwataHitoshi en-aut-sei=Ishiwata en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakashimaHiromu en-aut-sei=Nakashima en-aut-mei=Hiromu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Mandi?Sara en-aut-sei=Mandi? en-aut-mei=Sara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobayashiHina en-aut-sei=Kobayashi en-aut-mei=Hina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TeramotoMinori en-aut-sei=Teramoto en-aut-mei=Minori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsujiHirokazu en-aut-sei=Tsuji en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishibayashiYoshiki en-aut-sei=Nishibayashi en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShikanoYutaka en-aut-sei=Shikano en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AnToshu en-aut-sei=An en-aut-mei=Toshu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FujiwaraMasazumi en-aut-sei=Fujiwara en-aut-mei=Masazumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Chemistry, Graduate School of Life, Environmental, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=The National Institutes for Quantum Science and Technology (QST), Institute for Quantum Life Science (iQLS) kn-affil= affil-num=3 en-affil=Department of Chemistry, Graduate School of Life, Environmental, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Chemistry, Graduate School of Life, Environmental, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Department of Chemistry, Graduate School of Life, Environmental, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Advanced Materials Laboratory, Sumitomo Electric Industries, Ltd. kn-affil= affil-num=7 en-affil=Advanced Materials Laboratory, Sumitomo Electric Industries, Ltd. kn-affil= affil-num=8 en-affil=Advanced Materials Laboratory, Sumitomo Electric Industries, Ltd. kn-affil= affil-num=9 en-affil=Institute of Systems and Information Engineering, University of Tsukuba kn-affil= affil-num=10 en-affil=School of Materials Science, Japan Advanced Institute of Science and Technology kn-affil= affil-num=11 en-affil=Department of Chemistry, Graduate School of Life, Environmental, Natural Science and Technology, Okayama University kn-affil= en-keyword=nanodiamonds kn-keyword=nanodiamonds en-keyword=nitrogen-vacancy centers kn-keyword=nitrogen-vacancy centers en-keyword=spins kn-keyword=spins en-keyword=spin-relaxation times kn-keyword=spin-relaxation times en-keyword=quantum biosensor kn-keyword=quantum biosensor en-keyword=cellular probes kn-keyword=cellular probes END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=23 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241218 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Psychogenic fever and neurodevelopmental disorders among Japanese children en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Psychosocial stress can induce various physical symptoms, including fever, which is a commonly seen symptom in pediatric practice. In cases of unexplained fever, psychogenic fever should be considered as a potential cause. Children with neurodevelopmental disorders may be more vulnerable to stress and therefore more prone to developing somatic symptoms than their peers. This study aimed to elucidate the characteristics of children with psychogenic fever and comorbidity.
Methods This study included 21 patients with psychogenic fever who visited the Department of Pediatric Psychosomatic Medicine, Okayama University Hospital. Information on age, sex, disease onset, final estimated diagnosis, comorbidities, treatment course, and outcome was obtained from the patients' medical records.
Results Of the 21 patients included, 7 were boys and 14 were girls, and their median age was 13.0 (range: 8.6-14.6) years. A total of 19 patients had no attendance at school, and all patients showed signs of maladjustment in school. The comorbidities included orthostatic dysregulation (n = 4) and migraine (n = 3). Neurodevelopmental disorders were observed in nine patients, eight of whom were diagnosed after the initial visit. The mean treatment duration was 37.2 months. The outcomes were complete remission (n = 9), improvement (n = 4), discontinuation (n = 1), and referral to another physician (n = 7).
Conclusion Various comorbidities were observed in the patients of this study with psychogenic fever, including the coexistence of neurodevelopmental disorders, such as autistic spectrum disorder. Children with neurodevelopmental disorders are prone to psychological stress resulting from difficulties in social adjustment. It is crucial to understand the developmental characteristics and environmental adaptation of patients to facilitate accurate diagnosis and treatment. en-copyright= kn-copyright= en-aut-name=OkadaAyumi en-aut-sei=Okada en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShigeyasuYoshie en-aut-sei=Shigeyasu en-aut-mei=Yoshie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiChikako en-aut-sei=Fujii en-aut-mei=Chikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaChie en-aut-sei=Tanaka en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HanzawaMana en-aut-sei=Hanzawa en-aut-mei=Mana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SugiharaAkiko en-aut-sei=Sugihara en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HoriuchiMakiko en-aut-sei=Horiuchi en-aut-mei=Makiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Department of Pediatrics, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Pediatrics, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Psychogenic fever kn-keyword=Psychogenic fever en-keyword=Functional hyperthermia kn-keyword=Functional hyperthermia en-keyword=Neurodevelopmental disorder kn-keyword=Neurodevelopmental disorder en-keyword=Autism spectrum disorder kn-keyword=Autism spectrum disorder en-keyword=Environmental adaptation kn-keyword=Environmental adaptation END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=JAMDSM0001 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=Development of tool life prediction system for square end-mills based on database of servo motor current value en-subtitle= kn-subtitle= en-abstract= kn-abstract=Accurate prediction of tool life is crucial for reducing production costs and enhancing quality in the machining process. 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=159 cd-vols= no-issue=19 article-no= start-page=194504 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231121 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficiency and energy balance for substitution of CH4 in clathrate hydrates with CO2 under multiple-phase coexisting conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Many experimental and theoretical studies on CH4?CO2 hydrates have been performed aiming at the extraction of CH4 as a relatively clean energy resource and concurrent sequestration of CO2. However, vague or insufficient characterization of the environmental conditions prevents us from a comprehensive understanding of even equilibrium properties of CH4?CO2 hydrates for this substitution. We propose possible reaction schemes for the substitution, paying special attention to the coexisting phases, the aqueous and/or the fluid, where CO2 is supplied from and CH4 is transferred to. We address the two schemes for the substitution operating in three-phase and two-phase coexistence. Advantages and efficiencies of extracting CH4 in the individual scheme are estimated from the chemical potentials of all the components in all the phases involved in the substitution on the basis of a statistical mechanical theory developed recently. It is found that although substitution is feasible in the three-phase coexistence, its working window in temperature?pressure space is much narrower compared to the two-phase coexistence condition. Despite that the substitution normally generates only a small amount of heat, a large endothermic substitution is suggested in the medium pressure range, caused by the vaporization of liquid CO2 due to mixing with a small amount of the released CH4. This study provides the first theoretical framework toward the practical use of hydrates replacing CH4 with CO2 and serves as a basis for quantitative planning. en-copyright= kn-copyright= en-aut-name=TanakaHideki en-aut-sei=Tanaka en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoMasakazu en-aut-sei=Matsumoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YagasakiTakuma en-aut-sei=Yagasaki en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Division of Chemical Engineering, Graduate School of Engineering Science, Osaka University kn-affil= 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=228 cd-vols= no-issue= article-no= start-page=30 end-page=36 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241015 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Exogenous expression of PGC-1α during in vitro maturation impairs the developmental competence of porcine oocytes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives of the current study were to examine the effects of exogenous expression of PGC-1α, which is a transcription factor responsive for controlling mitochondrial DNA (mtDNA) replication, mitochondria quantity control, mitochondrial biogenesis, and reactive oxygen species (ROS) maintenance, in porcine oocytes during in-vitro maturation (IVM) on the developmental competence, as well as mitochondrial quantity and function. Exogenous over-expression of PGC-1α by injection of the mRNA construct into oocytes 20 h after the start of IVM culture significantly increased the copy number of mtDNA in the oocytes, but reduced the incidences of oocytes matured to the metaphase-II stage after the IVM culture for totally 44 h and completely suppressed the early development in vitro to the blastocyst stage following parthenogenetic activation. The exogenous expression of PGC-1α also significantly induced spindle defects and chromosome misalignments. Furthermore, markedly higher ROS levels were observed in the PGC-1α-overexpressed mature oocytes, whereas mRNA level of SOD1, encoded for a ROS scavenging enzyme, was decreased. These results conclude that forced expression of PGC-1α successfully increase mtDNA copy number but led to increased ROS production, evidently by downregulation of SOD1 gene expression, inducement of spindle aberration/chromosomal misalignment, and consequently reduction in the meiotic and developmental competences of porcine oocytes. en-copyright= kn-copyright= en-aut-name=DoSon Quang en-aut-sei=Do en-aut-mei=Son Quang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NguyenHai Thanh en-aut-sei=Nguyen en-aut-mei=Hai Thanh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WakaiTakuya en-aut-sei=Wakai en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FunahashiHiroaki en-aut-sei=Funahashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Porcine kn-keyword=Porcine en-keyword=Mitochondria kn-keyword=Mitochondria en-keyword=Oocytes kn-keyword=Oocytes en-keyword=PGC-1 alpha kn-keyword=PGC-1 alpha en-keyword=In vitro maturation kn-keyword=In vitro maturation END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue= article-no= start-page=53 end-page=63 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=What is education for sustainable development?: From the perspective of international legal history kn-title=持続可能な開発のための教育とは―国際法制史の視点から― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Throughout the history of international law, sustainable development has always been acknowledged as a global responsibility. In recent years, as global environmental concerns have escalated, this responsibility has become increasingly crucial. To fulfil this mandate, education policies must transcend national boundaries.

Although it is recommended that all mothers have the opportunity for early detection and intervention for postpartum depression, it is unclear whether early postpartum check-ups help to reduce postpartum depression.
Objective: The aim of this study was to assess the effect of 2-week postpartum check-ups on screening positive for postpartum depression in Japan.
Methods: This was a population-based cohort study that used the administrative database of Tsuyama, Japan. Participants were women who received postpartum home visits from a public health nurse in Tsuyama during the fiscal years 2017?2019. Data were obtained on participant’s attendance at a 2-week postpartum check-up and their responses on the Edinburgh Postpartum Depression Scale. Owing to the initiation of a publicly funded postpartum check-up programme, participants were pseudo-randomly assigned to receive/not receive a 2-week postpartum check-up. We conducted instrumental variable estimation to assess the causal effects of the check-up on screening positive for postpartum depression.
Results: The characteristics of the 1,382 participants did not differ by fiscal year of childbirth. We found a 6.7% (95% confidence interval 2.2?11.2) reduction in the prevalence of screening positive for postpartum depression as an effect of 2-week postpartum check-ups among women received 1-month postpartum home visits.
Conclusion: The results suggest that 2-week postpartum check-ups are effective in reducing the prevalence of screening positive for postpartum depression among 1-month postpartum women. Despite some limitations, early postpartum care could reduce postpartum depression. en-copyright= kn-copyright= en-aut-name=NakamuraNaoko en-aut-sei=Nakamura en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=NakashimaYasuko en-aut-sei=Nakashima en-aut-mei=Yasuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Health Promotion Division, Tsuyama City Department of Children’s Health kn-affil= affil-num=4 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=community health planning kn-keyword=community health planning en-keyword=diagnostic screening programmes kn-keyword=diagnostic screening programmes en-keyword=home visits kn-keyword=home visits en-keyword=postpartum depression kn-keyword=postpartum depression en-keyword=postnatal care kn-keyword=postnatal care en-keyword=quasi-experimental study kn-keyword=quasi-experimental study END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=23 article-no= start-page=10342 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=Assessing CO2 Reduction Effects Through Decarbonization Scenarios in the Residential and Transportation Sectors: Challenges and Solutions for Japan's Hilly and Mountainous Areas en-subtitle= kn-subtitle= en-abstract= kn-abstract=Depopulation, aging, and regional decline are becoming increasingly serious issues in Japan's hilly and mountainous areas. Focusing on mitigating environmental damage and envisioning a sustainable future for these regions, this study examines the potential for reducing CO2 emissions in the residential and transportation sectors by 2050. Bottom-up simulations were used to estimate CO2 emissions. Subsequently, six decarbonization scenarios were formulated, considering various measures from the perspectives of population distribution and technological progress. Based on these scenarios, this study analyzes changes in future population, energy consumption, and CO2 emissions by 2050. The results of this study show the following. (1) Depopulation and aging problems in these regions are expected to become more severe in the future. It is necessary to take action to promote sustainable regional development. (2) Pursuing decarbonization has a positive impact on enhancing regional sustainability; however, maintaining the intensity of measures at the current level could lead to a reduction of only 40% in CO2 emissions per capita by 2050 compared with 2020. (3) Scenarios that strengthen decarbonization measures could achieve a reduction of over 95% by 2050, indicating that carbon neutrality is attainable. However, this will require implementing measures at a higher intensity, especially in the transportation sector. en-copyright= kn-copyright= en-aut-name=HaoXiyue en-aut-sei=Hao en-aut-mei=Xiyue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YanChuyue en-aut-sei=Yan en-aut-mei=Chuyue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NarumiDaisuke en-aut-sei=Narumi en-aut-mei=Daisuke 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=Department of Socio-Environmental Energy Science, Graduate School of Energy Science, Kyoto University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=decarbonization measures kn-keyword=decarbonization measures en-keyword=CO2 reduction kn-keyword=CO2 reduction en-keyword=residential sector kn-keyword=residential sector en-keyword=transportation sector kn-keyword=transportation sector en-keyword=energy consumption kn-keyword=energy consumption en-keyword=CO2 emissions kn-keyword=CO2 emissions en-keyword=hilly and mountainous areas kn-keyword=hilly and mountainous areas en-keyword=area management kn-keyword=area management END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=1251 end-page=1273 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=Skewing Technology for Permanent Magnet Synchronous Motors: A Comprehensive Review and Recent Trends en-subtitle= kn-subtitle= en-abstract= kn-abstract=This article gives a comprehensive overview of the current research trends in the skewing technique for permanent magnet synchronous motors (PMSMs). The skewing technique has been widely used in many applications to reduce the cogging torque and torque ripple in PMSMs. There are many ways to implement the skew, and new techniques are continually being developed. First, this article summarizes the types of skew structures and presents a survey of existing techniques. Specific emphasis is placed on what kind of skew structure is selected depending on the PMSM configuration. Second, the optimal value of the skew angle for each structure is comprehensively explained, and the discrepancy between theory and finite element analysis is discussed. The definition of skew angle varies across the literature, and one of the purposes of this article is to organize the definition in an easy-to-understand manner. In addition, this article offers three-dimensional finite element analysis (3D-FEA) results of various PMSMs employing the skew for quantitative comparison. Then, this article discusses the properties of PMSMs using the skew by structure and the latest trends, and finally describes future prospects. en-copyright= kn-copyright= en-aut-name=TsunataRen en-aut-sei=Tsunata en-aut-mei=Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakemotoMasatsugu en-aut-sei=Takemoto en-aut-mei=Masatsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Additive manufacturing (AM) kn-keyword=Additive manufacturing (AM) en-keyword=axial leakage flux kn-keyword=axial leakage flux en-keyword=cogging torque kn-keyword=cogging torque en-keyword=electrical machine kn-keyword=electrical machine en-keyword=finite element analysis (FEA) kn-keyword=finite element analysis (FEA) en-keyword=induction motor (IM) kn-keyword=induction motor (IM) en-keyword=interior permanent magnet synchronous motor (IPMSM) kn-keyword=interior permanent magnet synchronous motor (IPMSM) en-keyword=noise kn-keyword=noise en-keyword=patents kn-keyword=patents en-keyword=permanent magnet synchronous motor (PMSM) kn-keyword=permanent magnet synchronous motor (PMSM) en-keyword=skew kn-keyword=skew en-keyword=surface permanent magnet synchronous motor (SPMSM) kn-keyword=surface permanent magnet synchronous motor (SPMSM) en-keyword=torque ripple kn-keyword=torque ripple en-keyword=total harmonic distortion (THD) kn-keyword=total harmonic distortion (THD) en-keyword=traction motor kn-keyword=traction motor en-keyword=transportation kn-keyword=transportation en-keyword=vibration kn-keyword=vibration END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=6 article-no= start-page=465 end-page=468 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=Secondary Polymyalgia Rheumatica Following SARS-CoV-2 Infection en-subtitle= kn-subtitle= en-abstract= kn-abstract=An 81-year-old Japanese man with a medical history of diabetes mellitus and hypertension was diagnosed with the novel coronavirus disease 2019 (COVID-19).

The clinical course of the patient indicated that the SARS-CoV-2 infection triggered the onset of autoimmune disease, PMR in this case. en-copyright= kn-copyright= en-aut-name=OchoKazuki en-aut-sei=Ocho en-aut-mei=Kazuki 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=IshikawaHisashi en-aut-sei=Ishikawa en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= affil-num=1 en-affil=Department of Internal Medicine, Ishikawa Hospital kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Internal Medicine, Ishikawa Hospital kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=SARS-CoV-2 kn-keyword=SARS-CoV-2 en-keyword=polymyalgia rheumatica kn-keyword=polymyalgia rheumatica en-keyword=autoimmune diseases kn-keyword=autoimmune diseases en-keyword=human leukocyte antigen kn-keyword=human leukocyte antigen END start-ver=1.4 cd-journal=joma no-vol=184 cd-vols= no-issue=1 article-no= start-page=24 end-page= 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=In vitro fertilization and long-term child health and development: nationwide birth cohort study in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study is to compare long-term health outcomes between IVF-conceived children and non-IVF-conceived children in Japan, in the context of strong recommendation for single embryo transfer. Using data from a nationwide birth cohort linked with perinatal database, this study analyzed 2140 children born in Japan in May 2010. It compared child health and development outcomes up to 9 years of age between IVF-conceived and non-IVF-conceived children (binary exposure). A Poisson regression with robust variance to estimate the risk ratios for the association between IVF and various long-term child health and developmental outcomes. After adjusting for confounding factors, no significant differences were observed between IVF-conceived and naturally conceived children for most outcomes, including hospitalization, obesity, and developmental milestones. IVF-conceived children showed a slightly lower risk of attention problems at 8 years (adjusted Risk Ratio [aRR]: 0.73, 95% CI: 0.53?1.00). In subgroup analyses, IVF-conceived term children and singletons demonstrated reduced risk of cognitive delays at 5.5 years (aRR: 0.31, 95% CI: 0.10?0.96 and aRR: 0.37, 95% CI: 0.14?0.98, respectively).
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=33 end-page=41 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230222 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Antimalarial effect of synthetic endoperoxide on synchronized Plasmodium chabaudi infected mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=The discovery of new antimalarial drugs can be developed using asynchronized Plasmodium berghei malaria parasites in vivo in mice. Studies on a particular stage are also required to assess the effectiveness and mode of action of drugs. In this report, we used endoperoxide 6-(1,2,6,7-tetraoxaspiro [7.11] nonadec-4-yl) hexan-1-ol (N-251) as a model antimalarial compound on P. chabaudi parasites. We examined the antimalarial effect of N-251 against ring-stage- and trophozoite-stage-rich P. chabaudi parasites and asynchronized P. berghei parasites using the 4-day suppressive test. The ED50 values were 27, 22, and 22 mg/kg, respectively, and the antimalarial activity of N-251 was verified in both rodent malaria parasites. To assess the stage-specific effect of N-251 in vivo, we evaluated the change of parasitemia and distribution of parasite stages using ring-stage- and trophozoite-stage-rich P. chabaudi parasites with one-day drug administration for one life cycle. We discovered that the parasitemias decreased after 13 and 9 hours post-treatment in the ring-stage- and trophozoite-stage-rich groups, respectively. Additionally, in the ring-stage-rich N-251 treated group, the ring-stage parasites hindered trophozoite parasite development. For the trophozoite-stage-rich N-251 treated group, the distribution of the trophozoite stage was maintained without a change in parasitemia until 9 hours. Because of these findings, it can be concluded that N-251 suppressed the trophozoite stage but not the ring stage. We report for the first time that N-251 specifically suppresses the trophozoite stage using P. chabaudi in mice. The results show that P. chabaudi is a reliable model for the characterization of stage-specific antimalarial effects. en-copyright= kn-copyright= en-aut-name=AlyNagwa S.

In environments with unknown objects, the ability to perform a local planner, which modifies the global path based on the perception results, is also required as an indispensable capability. In this paper, we propose a method based on Growing Neural Gas with Different Topologies (GNG-DT), which can be applied to unknown data, as a method for 3D spatial perception and local planner in unknown environments. First, we propose a method for extracting travelability perceptions from the features estimated by the topological structure of the GNG-DT. Next, we learn the topological structure of passability information based on the size of the robot from the extracted traversability percepts. Furthermore, we propose a local planner that uses the topological structure of traversability and passability learned from the point cloud currently perceived by the robot. In the experiments, we compared the cases where only traversability was used and where passability information was used in actual environments, and showed that the proposed method can plan a route that determines the area that the robot can actually pass through. en-copyright= kn-copyright= en-aut-name=OzasaKoki en-aut-sei=Ozasa en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=MasudaToshiki en-aut-sei=Masuda en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KonishiHirohide en-aut-sei=Konishi en-aut-mei=Hirohide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsunoTakayuki en-aut-sei=Matsuno en-aut-mei=Takayuki 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=Tokyo Metropolitan Industrial Technology Research Institute kn-affil= affil-num=4 en-affil=Tokyo Metropolitan Industrial Technology Research Institute kn-affil= affil-num=5 en-affil=NSK Ltd. kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Autonomous mobile robot kn-keyword=Autonomous mobile robot en-keyword=growing neural gas kn-keyword=growing neural gas en-keyword=local planner kn-keyword=local planner END start-ver=1.4 cd-journal=joma no-vol=36 cd-vols= no-issue=10 article-no= start-page=4585 end-page=4606 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241029 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mobile Augmented Reality Interface for Instruction-based Disaster Preparedness Guidelines en-subtitle= kn-subtitle= en-abstract= kn-abstract=Disaster preparedness guidelines help citizens protect themselves against disasters. Nonetheless, the general public has been found not to read them. Augmented reality (AR) interfaces are known to improve knowledge transfer in studies of education, industry, and elderly assistance. However, this is achieved this by creating specific interfaces for users, not the general public. To test the performance of these interfaces for general public guidance, we designed and implemented a novel AR-assisted disaster prevention guideline that leverages object detection models to identify targets of disaster preparedness advice. We then had a diverse-age audience compare our design against a real traditional paper-based preparedness guide in a room arranged as a common remote work bedroom. By testing their usability, task load, and capacity to make users aware of their environmental hazards, we gained important insights into the performance of different age groups following media developed for the general public. Regardless of different age groups achieving similar usability scores, we found minors improving their performance scores with our novel interface and adults from 20 to 49 years old seemingly performing better than other age groups. In this study, we highlight the importance of guidance alternatives for the young and the less-technology-aware population, contributing to the under-explored area of AR interfaces for the general public. en-copyright= kn-copyright= en-aut-name=AguilarSergio De Le?n en-aut-sei=Aguilar en-aut-mei=Sergio De Le?n kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsudaYuki en-aut-sei=Matsuda en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasumotoKeiichi en-aut-sei=Yasumoto en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Information Science, Nara Institute of Science and Technology kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Information Science, Nara Institute of Science and Technology kn-affil= en-keyword=guidelines kn-keyword=guidelines en-keyword=augmented reality kn-keyword=augmented reality en-keyword=disaster preparedness kn-keyword=disaster preparedness en-keyword=object recognition kn-keyword=object recognition en-keyword=user interface kn-keyword=user interface en-keyword=knowledge transfer kn-keyword=knowledge transfer END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=11 article-no= start-page=upae196 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241022 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=SNAr hexafluoroisopropoxylation of electron-rich aryl fluoride with a catalytic electrical input en-subtitle= kn-subtitle= en-abstract= kn-abstract=Anodic oxidation?promoted SNAr reactions of electron-rich aryl fluoride were developed. The anodic oxidation of 4-fluoroanisole in hexafluoroisopropyl alcohol (HFIP) with K2CO3 led to SNAr-type hexafluoroisopropoxylation, and the reaction was completed with a catalytic electrical input. The results of cyclic voltammetry suggest that the radical cation of 4-fluoroanisole, which would react with the alkoxide of HFIP, is generated. Electron transfer between the intermediate and the starting material constructs the catalytic cycle, and the elimination of fluoride from the Meisenheimer complex produces the desired compound. en-copyright= kn-copyright= en-aut-name=SatoEisuke en-aut-sei=Sato en-aut-mei=Eisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakahamaTomohiro en-aut-sei=Nakahama en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitsudoKoichi en-aut-sei=Mitsudo en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=anodic oxidation kn-keyword=anodic oxidation en-keyword=organic electrochemistry kn-keyword=organic electrochemistry en-keyword=SNAr reaction kn-keyword=SNAr reaction END start-ver=1.4 cd-journal=joma no-vol=169 cd-vols= no-issue= article-no= start-page=106712 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20249 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The parallel stack loading problem of minimizing the exact number of relocations en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study addresses the parallel stack loading problem, a general optimization problem arising in storage facilities such as container yards, slab yards, and warehouses. In this problem, we load incoming items into parallel stacks in the loading phase to minimize the number of relocations in the subsequent retrieval phase. Because of difficulties in treating the nested problem structure originating from the mutual dependence of the two phases, the existing studies approximately minimized the number of relocations using surrogate objective functions. In contrast, this study considers the parallel stack loading problem aiming to minimize the exact number of relocations. We first provide an integer programming formulation and next develop a nested branch-and-bound algorithm. In a computational study, we verify the effectiveness of the proposed branch-and-bound algorithm and evaluate the known surrogate objective functions based on the exact minimization. en-copyright= kn-copyright= en-aut-name=TanakaShunji en-aut-sei=Tanaka en-aut-mei=Shunji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ElWakilMohamed en-aut-sei=ElWakil en-aut-mei=Mohamed kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EltawilAmr en-aut-sei=Eltawil en-aut-mei=Amr kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life and Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Production Engineering and Mechanical Design, Faculty of Engineering, Tanta University kn-affil= affil-num=3 en-affil=Department of Industrial and Manufacturing Engineering, Egypt Japan University of Science and Technology kn-affil= en-keyword=Logistics kn-keyword=Logistics en-keyword=Parallel stack loading problem kn-keyword=Parallel stack loading problem en-keyword=Relocation kn-keyword=Relocation en-keyword=Integer programming kn-keyword=Integer programming en-keyword=Branch-and-bound algorithm kn-keyword=Branch-and-bound algorithm END start-ver=1.4 cd-journal=joma no-vol=300 cd-vols= no-issue=3 article-no= start-page=105679 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Methyl vinyl ketone and its analogs covalently modify PI3K and alter physiological functions by inhibiting PI3K signaling en-subtitle= kn-subtitle= en-abstract= kn-abstract=Reactive carbonyl species (RCS), which are abundant in the environment and are produced in vivo under stress, covalently bind to nucleophilic residues such as Cys in proteins. Disruption of protein function by RCS exposure is predicted to play a role in the development of various diseases such as cancer and metabolic disorders, but most studies on RCS have been limited to simple cytotoxicity validation, leaving their target proteins and resulting physiological changes unknown. In this study, we focused on methyl vinyl ketone (MVK), which is one of the main RCS found in cigarette smoke and exhaust gas. We found that MVK suppressed PI3K-Akt signaling, which regulates processes involved in cellular homeostasis, including cell proliferation, autophagy, and glucose metabolism. Interestingly, MVK inhibits the interaction between the epidermal growth factor receptor and PI3K. Cys656 in the SH2 domain of the PI3K p85 subunit, which is the covalently binding site of MVK, is important for this interaction. Suppression of PI3K- Akt signaling by MVK reversed epidermal growth factor- induced negative regulation of autophagy and attenuated glucose uptake. Furthermore, we analyzed the effects of the 23 RCS compounds with structures similar to MVK and showed that their analogs also suppressed PI3K-Akt signaling in a manner that correlated with their similarities to MVK. Our study demonstrates the mechanism of MVK and its analogs in suppressing PI3K-Akt signaling and modulating physiological functions, providing a model for future studies analyzing environmental reactive species. en-copyright= kn-copyright= en-aut-name=MorimotoAtsushi en-aut-sei=Morimoto en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakasugiNobumasa en-aut-sei=Takasugi en-aut-mei=Nobumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=PanYuexuan en-aut-sei=Pan en-aut-mei=Yuexuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KubotaSho en-aut-sei=Kubota en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=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=AbikoYumi en-aut-sei=Abiko en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UchidaKoji en-aut-sei=Uchida en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KumagaiYoshito en-aut-sei=Kumagai en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UeharaTakashi en-aut-sei=Uehara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Biomolecular Characterization Unit, Technology Platform Division, RIKEN Center for Sustainable Resource Science kn-affil= affil-num=6 en-affil=Graduate School of Biomedical Science, Nagasaki University kn-affil= affil-num=7 en-affil=Laboratory of Food Chemistry, Graduate School of Agricultural and Life Sciences, The University of Tokyo kn-affil= affil-num=8 en-affil=Graduate School of Pharmaceutical Sciences, Kyushu University kn-affil= affil-num=9 en-affil=Department of Medicinal Pharmacology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=phosphatidylinositol 3-kinase (PI 3-kinase) kn-keyword=phosphatidylinositol 3-kinase (PI 3-kinase) en-keyword=cell signaling kn-keyword=cell signaling en-keyword=chemical modification kn-keyword=chemical modification en-keyword=autophagy kn-keyword=autophagy en-keyword=glucose uptake kn-keyword=glucose uptake END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=2400024 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structural Evolution of Microgels During Precipitation Polymerization Revealed by Light Scattering and Electrophoresis en-subtitle= kn-subtitle= en-abstract= kn-abstract=While precipitation polymerization allows the synthesis of microgels with controlled functional-group distributions, the structural development of these microgels during the polymerization process still remains unclear. In this study, microgels with different reactivity ratios between the monomer and charged co-monomer are prepared by precipitation polymerization, and the evolution of their size, thermoresponsive behavior, and surface properties during polymerization are evaluated. In particular, the surface properties of the microgels are analyzed quantitatively using the softness parameter and the surface charge density is calculated using Ohshima's equation. The results allowed describing the structural changes of microgels during precipitation polymerization well and provided design guidelines for functional microgels with controlled functional group distributions. en-copyright= kn-copyright= en-aut-name=SatoYuji en-aut-sei=Sato en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NamiokaRyuji en-aut-sei=Namioka en-aut-mei=Ryuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=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 Sciences and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Textile Science & Technology, Shinshu Universit kn-affil= affil-num=3 en-affil=Graduate School of Environmental Life, Natural Sciences and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental Life, Natural Sciences and Technology, Okayama University kn-affil= en-keyword=electrokinetic phenomena kn-keyword=electrokinetic phenomena en-keyword=microgel kn-keyword=microgel en-keyword=nanogels kn-keyword=nanogels en-keyword=precipitation polymerization kn-keyword=precipitation polymerization en-keyword=radical polymerization kn-keyword=radical polymerization en-keyword=thermoresponsive kn-keyword=thermoresponsive END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=20 article-no= start-page=1677 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241018 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Colossal Dielectric Constant of Nanocrystalline/Amorphous Homo-Composite BaTiO3 Films Deposited via Pulsed Laser Deposition Technique en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report the pulsed laser deposition (PLD) of nanocrystalline/amorphous homo-composite BaTiO3 (BTO) films exhibiting an unprecedented combination of a colossal dielectric constant (epsilon(r)) and extremely low dielectric loss (tan delta). By varying the substrate deposition temperature (T-d) over a wide range (300-800 degrees C), we identified T-d = 550 degrees C as the optimal temperature for growing BTO films with an epsilon(r) as high as similar to 3060 and a tan delta as low as 0.04 (at 20 kHz). High-resolution transmission electron microscopy revealed that the PLD-BTO films consist of BTO nanocrystals (similar to 20-30 nm size) embedded within an otherwise amorphous BTO matrix. The impressive dielectric behavior is attributed to the combination of highly crystallized small BTO nanograins, which amplify interfacial polarization, and the surrounding amorphous matrix, which effectively isolates the nanograins from charge carrier transport. Our findings could facilitate the development of next-generation integrated dielectric devices. 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=MurakamiTaichi en-aut-sei=Murakami en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=PichonLoick en-aut-sei=Pichon en-aut-mei=Loick kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Leblanc-LavoieJoel en-aut-sei=Leblanc-Lavoie en-aut-mei=Joel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TeranishiTakashi en-aut-sei=Teranishi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KishimotoAkira en-aut-sei=Kishimoto en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=El KhakaniKhakani, My Ali en-aut-sei=El Khakani en-aut-mei=Khakani, My Ali kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Institut National de la Recherche Scientifique (INRS), Centre ?nergie, Mat?riaux et T?l?communications kn-affil= affil-num=4 en-affil=Institut National de la Recherche Scientifique (INRS), Centre ?nergie, Mat?riaux et T?l?communications 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=Institut National de la Recherche Scientifique (INRS), Centre ?nergie, Mat?riaux et T?l?communications kn-affil= en-keyword=BaTiO3 kn-keyword=BaTiO3 en-keyword=thin film kn-keyword=thin film en-keyword=colossal dielectric constant kn-keyword=colossal dielectric constant en-keyword=nanocrystalline/amorphous homo-composite kn-keyword=nanocrystalline/amorphous homo-composite en-keyword=pulsed laser deposition kn-keyword=pulsed laser deposition END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=10 article-no= start-page=614 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241007 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Independent Learning System for Flutter Cross-Platform Mobile Programming with Code Modification Problems en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, with the common use of smartphones in daily lives, mobile applications have become popular around the world, which will lead to a rise in Flutter framework. Developed by Google, Flutter with Dart programming provides a cross-platform development environment to create visually appealing and responsive user interfaces across mobile, web, and desktop platforms using a single codebase. However, due to time and staff limitations, the Flutter/Dart programming course is not included in curricula, even in IT departments in universities. Therefore, independent learning environments for students are essential to meet this growing popularity. Previously, we have developed programming learning assistant system (PLAS) as a web-browser-based self-learning platform for novice students. PLAS offers various types of exercise problems designed to cultivate programming skills step-by-step through a lot of code reading and code writing practices. Among them, one particular type is the code modification problem (CMP), which asks to modify the given source code to satisfy the new specifications. CMP is expected to be solved by novices with little effort if they have knowledge of other programming languages. Thus, PLAS with CMP will be an excellent platform for independent learning. In this paper, we present PLAS with CMP for the independent learning of Flutter/Dart programming. To improve the readability of the source code by students, we provided rich comments on grammar or behaviors. Besides, the code can be downloaded so that students can check and run it on an IDE. For evaluations, we generated 38 CMP instances for basic and multimedia/storage topics in Flutter/Dart programming and assigned them to 21 master students at Okayama University, Japan, who have never studied it. The results confirm the validity of the proposal. en-copyright= kn-copyright= en-aut-name=KinariSafira Adine en-aut-sei=Kinari en-aut-mei=Safira Adine kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=AungSoe Thandar en-aut-sei=Aung en-aut-mei=Soe Thandar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WaiKhaing Hsu en-aut-sei=Wai en-aut-mei=Khaing Hsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=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=Flutter kn-keyword=Flutter en-keyword=Dart kn-keyword=Dart en-keyword=cross-platform kn-keyword=cross-platform en-keyword=programming kn-keyword=programming en-keyword=code modification problem kn-keyword=code modification problem en-keyword=PLAS kn-keyword=PLAS en-keyword=independent learning kn-keyword=independent learning END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=5 article-no= start-page=387 end-page=399 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=Effect of Radon Inhalation on Murine Brain Proteins: Investigation Using Proteomic and Multivariate Analyses en-subtitle= kn-subtitle= en-abstract= kn-abstract=Radon is a known risk factor for lung cancer; however, it can be used beneficially, such as in radon therapy. We have previously reported the enhancement of antioxidant effects associated with trace amounts of oxidative stress as one of the positive biological effects of radon inhalation. However, the biological effects of radon inhalation are incompletely understood, and more detailed and comprehensive studies are required. Although several studies have used proteomics to investigate the effects of radon inhalation on body proteins, none has focused on brain proteins. In this study, we evaluated the expression status of proteins in murine brains using proteomic and multivariate analyses to identify those whose expressions changed following two days of radon inhalation at a concentration of 1,500 Bq/m3. We found associations of radon inhalation with the expressions of seven proteins related to neurotransmission and heat shock. These proteins may be proposed as biomarkers indicative of radon inhalation. Although further studies are required to obtain the detailed biological significance of these protein alterations, this study contributes to the elucidation of the biological effects of radon inhalation as a low-dose radiation. en-copyright= kn-copyright= en-aut-name=NaoeShota en-aut-sei=Naoe en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaAyumi en-aut-sei=Tanaka en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanzakiNorie en-aut-sei=Kanzaki en-aut-mei=Norie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakenakaReiju en-aut-sei=Takenaka en-aut-mei=Reiju kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakodaAkihiro en-aut-sei=Sakoda en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyajiTakaaki en-aut-sei=Miyaji en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamaokaKiyonori en-aut-sei=Yamaoka en-aut-mei=Kiyonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KataokaTakahiro en-aut-sei=Kataoka en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=4 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=6 en-affil=Advanced Science Research Center, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Health Sciences, Okayama University kn-affil= affil-num=8 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=radon inhalation kn-keyword=radon inhalation en-keyword=proteomics kn-keyword=proteomics en-keyword=multivariate analysis kn-keyword=multivariate analysis en-keyword=brain kn-keyword=brain en-keyword=oxidative stress kn-keyword=oxidative stress END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=9 article-no= start-page=215 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240823 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Study of a Drawing Exactness Assessment Method Using Localized Normalized Cross-Correlations in a Portrait Drawing Learning Assistant System en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, portrait drawing has gained significance in cultivating painting skills and human sentiments. In practice, novices often struggle with this art form without proper guidance from professionals, since they lack understanding of the proportions and structures of facial features. To solve this limitation, we have developed a Portrait Drawing Learning Assistant System (PDLAS) to assist novices in learning portrait drawing. The PDLAS provides auxiliary lines as references for facial features that are extracted by applying OpenPose and OpenCV libraries to a face photo image of the target. A learner can draw a portrait on an iPad using drawing software where the auxiliary lines appear on a different layer to the portrait. However, in the current implementation, the PDLAS does not offer a function to assess the exactness of the drawing result for feedback to the learner. In this paper, we present a drawing exactness assessment method using a Localized Normalized Cross-Correlation (NCC) algorithm in the PDLAS. NCC gives a similarity score between the original face photo and drawing result images by calculating the correlation of the brightness distributions. For precise feedback, the method calculates the NCC for each face component by extracting the bounding box. In addition, in this paper, we improve the auxiliary lines for the nose. For evaluations, we asked students at Okayama University, Japan, to draw portraits using the PDLAS, and applied the proposed method to their drawing results, where the application results validated the effectiveness by suggesting improvements in drawing components. The system usability was also confirmed through a questionnaire with a SUS score. The main finding of this research is that the implementation of the NCC algorithm within the PDLAS significantly enhances the accuracy of novice portrait drawings by providing detailed feedback on specific facial features, proving the system's efficacy in art education and training. 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=KongZitong en-aut-sei=Kong en-aut-mei=Zitong 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=HsuChen-Chien en-aut-sei=Hsu en-aut-mei=Chen-Chien 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 Sciences and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Sciences and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Sciences and Technology, Okayama University kn-affil= affil-num=4 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=exactness assessment kn-keyword=exactness assessment END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=9 article-no= start-page=471 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240909 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Generating 3D Models for UAV-Based Detection of Riparian PET Plastic Bottle Waste: Integrating Local Social Media and InstantMesh en-subtitle= kn-subtitle= en-abstract= kn-abstract=In recent years, waste pollution has become a severe threat to riparian environments worldwide. Along with the advancement of deep learning (DL) algorithms (i.e., object detection models), related techniques have become useful for practical applications. This work attempts to develop a data generation approach to generate datasets for small target recognition, especially for recognition in remote sensing images. A relevant point is that similarity between data used for model training and data used for testing is crucially important for object detection model performance. Therefore, obtaining training data with high similarity to the monitored objects is a key objective of this study. Currently, Artificial Intelligence Generated Content (AIGC), such as single target objects generated by Luma AI, is a promising data source for DL-based object detection models. However, most of the training data supporting the generated results are not from Japan. Consequently, the generated data are less similar to monitored objects in Japan, having, for example, different label colors, shapes, and designs. For this study, the authors developed a data generation approach by combining social media (Clean-Up Okayama) and single-image-based 3D model generation algorithms (e.g., InstantMesh) to provide a reliable reference for future generations of localized data. The trained YOLOv8 model in this research, obtained from the S2PS (Similar to Practical Situation) AIGC dataset, produced encouraging results (high F1 scores, approximately 0.9) in scenario-controlled UAV-based riparian PET bottle waste identification tasks. The results of this study show the potential of AIGC to supplement or replace real-world data collection and reduce the on-site work load. 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=ShimoeDaichi en-aut-sei=Shimoe en-aut-mei=Daichi 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=NishiyamaSatoshi en-aut-sei=Nishiyama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=TOKEN C.E.E.

When an alloy sample that has been strained by external force at room temperature is heated, the strain recovers and SM effect develops at around 300℃, but as the temperature increases further, the shape changes in the opposite direction due to RSM effect at around 450℃. This RSM effect has potential applications in forming processes such as thin-walled pipes, but has the disadvantage that the RSM treatment makes the material very brittle. Therefore, in this study, a heat treatment to restore toughness while maintaining the shape after forming was investigated. The alloy quenched from 1050℃ had a microstructure consisting of a β matrix phase and α′′-martensite (α′′Mq). Differential scanning calorimetry (DSC) results showed that the continuous heating process occurred in the following order: α′′Mq → β reverse transformation, ω formation, ω disappearance, thermally induced α′′iso phase formation, α precipitation and α → β transformation. Ageing at 300℃, where the SM effect appears, caused significant embrittlement due to the formation of the ageing ω phase. Ageing treatment at 450℃, where the RSM effect is obtained, resulted in the formation of a fine α phase, which also caused significant embrittlement. On the other hand, additional aging at 600℃ for 1.8 ks after RSM treatment significantly improved the toughness and produced material properties comparable to aerospace material specifications. It was found that the embrittlement in the RSM treatment was due to the precipitation of fine α phase, and that the growth of α phase with a width of about 0.2 ?m or more was required for toughness recovery. It was also found that the specimen shape formed by the RSM treatment hardly changed after the additional heat treatment of 1.8 ks at 600℃. en-copyright= kn-copyright= en-aut-name=TakemotoYoshito en-aut-sei=Takemoto en-aut-mei=Yoshito kn-aut-name=竹元嘉利 kn-aut-sei=竹元 kn-aut-mei=嘉利 aut-affil-num=1 ORCID= en-aut-name=ShinomiyaDaiki en-aut-sei=Shinomiya en-aut-mei=Daiki kn-aut-name=四宮大輝 kn-aut-sei=四宮 kn-aut-mei=大輝 aut-affil-num=2 ORCID= en-aut-name=IshiharaTaiki en-aut-sei=Ishihara en-aut-mei=Taiki kn-aut-name=石原大暉 kn-aut-sei=石原 kn-aut-mei=大暉 aut-affil-num=3 ORCID= en-aut-name=YokotaHiroto en-aut-sei=Yokota en-aut-mei=Hiroto kn-aut-name=横田啓人 kn-aut-sei=横田 kn-aut-mei=啓人 aut-affil-num=4 ORCID= en-aut-name=ArakawaJinta en-aut-sei=Arakawa en-aut-mei=Jinta kn-aut-name=荒川仁太 kn-aut-sei=荒川 kn-aut-mei=仁太 aut-affil-num=5 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学環境生命自然科学学域 affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学大学院環境生命自然科学研究科 affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学大学院環境生命自然科学研究科 affil-num=5 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学環境生命自然科学学域 en-keyword=reverse shape memory kn-keyword=reverse shape memory en-keyword=α′′-phase kn-keyword=α′′-phase en-keyword=deformation induced martensite kn-keyword=deformation induced martensite en-keyword=β-type titanium alloy kn-keyword=β-type titanium alloy en-keyword=brittle fracture kn-keyword=brittle fracture en-keyword=toughness kn-keyword=toughness en-keyword=shape recovery kn-keyword=shape recovery en-keyword=ω-phase kn-keyword=ω-phase en-keyword=variant kn-keyword=variant END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=1339958 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240829 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Illumina-based transcriptomic analysis of the fast-growing leguminous tree Acacia crassicarpa: functional gene annotation and identification of novel SSR-markers en-subtitle= kn-subtitle= en-abstract= kn-abstract=Acacia crassicarpa is a fast-growing leguminous tree that is widely cultivated in tropical areas such as Indonesia, Malaysia, Australia, and southern China. This tree has versatile utility in timber, furniture, and pulp production. Illumina sequencing of A. crassicarpa was conducted, and the raw data of 124,410,892 reads were filtered and assembled de novo into 93,317 unigenes, with a total of 84,411,793 bases. Blast2GO annotation, Benchmark Universal Single-Copy Ortholog evaluation, and GO-term classification produced a catalogue of unigenes for studying primary metabolism, phytohormone signaling, and transcription factors. Massive transcriptomic analysis has identified microsatellites composed of simple sequence repeat (SSR) loci representing di-, tri-, and tetranucleotide repeat units in the predicted open reading frames. Polymorphism was induced by PCR amplification of microsatellite loci located in several genes encoding auxin response factors and other transcription factors, which successfully distinguished 16 local trees of A. crassicarpa tested, representing potentially exploitable molecular markers for efficient tree breeding for plantation and biomass exploitation. en-copyright= kn-copyright= en-aut-name=IshioShougo en-aut-sei=Ishio en-aut-mei=Shougo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KusunokiKazutaka en-aut-sei=Kusunoki en-aut-mei=Kazutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NemotoMichiko en-aut-sei=Nemoto en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KanaoTadayoshi en-aut-sei=Kanao en-aut-mei=Tadayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TamuraTakashi en-aut-sei=Tamura en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Tsukuba Research Institute, Sumitomo Forestry Co.

However, the simultaneous optimization of packing and the robot's motion planning is challenging because these two decisions are interconnected, and no previous study has addressed this optimization problem. This paper presents a framework to simultaneously determine the robot's motion planning and packing decision to minimize the robot's processing time and the container's volume. This framework comprises three key components: solution encoding, surrogate modeling, and evolutionary computation. The sequence-triple representation encodes complex packing solutions by a sequence of integers. A surrogate model is trained to predict the processing time for a given packing solution to reduce the computational burden. Training data is generated by solving the motion planning problem for a set of packing solutions using the rapidly exploring random tree algorithm. The Non-Dominated Sorting Genetic Algorithm II searches for the Pareto solutions. Experimental evaluations are conducted using a 6-DOF robot manipulator. The experimental results suggest that implementing the surrogate model can reduce the computational time by 91.1%. The proposed surrogate-assisted optimization method can obtain significantly better solutions than the joint angular velocity-based estimation method. en-copyright= kn-copyright= en-aut-name=LiuZiang en-aut-sei=Liu en-aut-mei=Ziang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawabeTomoya en-aut-sei=Kawabe en-aut-mei=Tomoya 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= en-aut-name=ItoShun en-aut-sei=Ito en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujiwaraTomofumi en-aut-sei=Fujiwara en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Packing problem kn-keyword=Packing problem en-keyword=sequence-triple kn-keyword=sequence-triple en-keyword=motion planning kn-keyword=motion planning en-keyword=surrogate model kn-keyword=surrogate model en-keyword=multi-objective optimization kn-keyword=multi-objective optimization END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=1403922 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240820 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lentil adaptation to drought stress: response, tolerance, and breeding approaches en-subtitle= kn-subtitle= en-abstract= kn-abstract=Lentil (Lens culinaris Medik.) is a cool season legume crop that plays vital roles in food and nutritional security, mostly in the least developed countries. Lentil is often cultivated in dry and semi-dry regions, where the primary abiotic factor is drought, which negatively impacts lentil growth and development, resulting in a reduction of yield. To withstand drought-induced multiple negative effects, lentil plants evolved a variety of adaptation strategies that can be classified within three broad categories of drought tolerance mechanisms (i.e., escape, avoidance, and tolerance). Lentil adapts to drought by the modulation of various traits in the root system, leaf architecture, canopy structure, branching, anatomical features, and flowering process. Furthermore, the activation of certain defensive biochemical pathways as well as the regulation of gene functions contributes to lentil drought tolerance. Plant breeders typically employ conventional and mutational breeding approaches to develop lentil varieties that can withstand drought effects; however, little progress has been made in developing drought-tolerant lentil varieties using genomics-assisted technologies. This review highlights the current understanding of morpho-physiological, biochemical, and molecular mechanisms of lentil adaptation to drought stress. We also discuss the potential application of omics-assisted breeding approaches to develop lentil varieties with superior drought tolerance traits. en-copyright= kn-copyright= en-aut-name=NoorMd.

Although its ecological and evolutionary consequences have attracted much attention, how reproductive interference affects the population genetic structures of interacting species is still unclear. In flowering plants, recent studies found that self-pollination can mitigate the negative effects of reproductive interference. Selfing-biased seed production is expected to increase population-level inbreeding and the selfing rate, and limits gene flow via pollinator outcrossing among populations. We examined the population genetics of the mixed-mating annual herb Commelina communis f. ciliata, focusing on reproductive interference by the sympatric competing congener C. communis using microsatellite markers. First, we found that almost all C. c. f. ciliata populations had relatively high inbreeding coefficients. Then, comparing sympatric and allopatric populations, we found evidence that reproductive interference from a competing congener increased the inbreeding coefficient and selfing rate. Allopatric populations exhibit varied selfing rates while almost all sympatric populations exhibit extremely high selfing rates, suggesting that population selfing rates were also influenced by unexamined factors, such as pollinator limitation. Besides, our findings revealed that reproductive interference from a competing congener did not limit gene flow among populations. We present the first report on how reproductive interference affects the genetic aspects of populations. Our results suggested that the high selfing rate of C. c. f. ciliata promotes its sympatric distribution with C. communis, even in the presence of reproductive interference, although it is not clear whether reproductive interference directly causes the high selfing rate. en-copyright= kn-copyright= en-aut-name=KatsuharaKoki R. en-aut-sei=Katsuhara en-aut-mei=Koki R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UshimaruAtushi en-aut-sei=Ushimaru en-aut-mei=Atushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyazakiYuko en-aut-sei=Miyazaki en-aut-mei=Yuko 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 Human Development and Environment, Kobe University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Commelina kn-keyword=Commelina en-keyword=Genetic diversity kn-keyword=Genetic diversity en-keyword=Inbreeding coefficient kn-keyword=Inbreeding coefficient en-keyword=Mixed mating kn-keyword=Mixed mating en-keyword=Population genetics kn-keyword=Population genetics END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue= article-no= start-page=100347 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=Reduction with zinc - Impact on the determination of nitrite and nitrate ions using microfluidic paper-based analytical devices en-subtitle= kn-subtitle= en-abstract= kn-abstract=We used a microfluidic paper-based analytical device (mu PAD) to investigate the influence that zinc reduction exerts on the determination of nitrite and nitrate ions in natural water samples. The mu PAD consists of layered channels for the reduction of nitrate to nitrite with zinc powder and the subsequent detection of nitrite with Griess reagent. The amount of zinc, number of layers, and reaction time for the reduction were optimized to obtain an intense signal for nitrate. Initially, the sensitivity to nitrate corresponded to 55% that of nitrite, which implied an incomplete reduction. We found, however, that zinc decreased the sensitivity to nitrite in both the mu PAD and spectrophotometry. The sensitivity to nitrite was decreased by 48% in spectrophotometry and 68% in the mu PAD following the reaction with zinc. One of the reasons for the decreased sensitivity is attributed to the production of ammonia, as we elucidated that both nitrite and nitrate produced ammonia via the reaction with zinc. The results suggest that the total concentration of nitrite and nitrate must be corrected by constructing a calibration curve for nitrite with zinc, in addition to developing curves for nitrate with zinc and for nitrite without zinc. Using these calibration curves, the absorbance at different concentration ratios of nitrite and nitrate ions could be reproduced via calculation using the calibration curves with zinc for nitrite and nitrate. Eventually, the developed mu PAD was applied to the determination of nitrite and nitrate ions in natural water samples, and the results were compared with those using a conventional spectrophotometric method. The results of the mu PAD are in good agreement with those of conventional spectrophotometry, which suggests that the mu PAD is reliable for the measurement of nitrite and nitrate ions in natural water samples. en-copyright= kn-copyright= en-aut-name=UmedaMika I. en-aut-sei=Umeda en-aut-mei=Mika I. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=FujiiTakatoshi en-aut-sei=Fujii en-aut-mei=Takatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HinoEiichi en-aut-sei=Hino en-aut-mei=Eiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DateYusuke en-aut-sei=Date en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AokiKaoru en-aut-sei=Aoki en-aut-mei=Kaoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Okayama University kn-affil= affil-num=3 en-affil=National Institute of Technology, Yonago College kn-affil= affil-num=4 en-affil=National Institute of Technology, Yonago College kn-affil= affil-num=5 en-affil=National Institute of Technology, Yonago College kn-affil= affil-num=6 en-affil=National Institute of Technology, Yonago College kn-affil= affil-num=7 en-affil=Okayama University kn-affil= en-keyword=Microfluidic paper-based analytical device kn-keyword=Microfluidic paper-based analytical device en-keyword=Nitrite ion kn-keyword=Nitrite ion en-keyword=Nitrate ion kn-keyword=Nitrate ion en-keyword=On-site analysis kn-keyword=On-site analysis en-keyword=Environmental analysis kn-keyword=Environmental analysis END start-ver=1.4 cd-journal=joma no-vol=40 cd-vols= no-issue=32 article-no= start-page=16994 end-page=17000 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240730 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Droplet-Removal Processes on Fog-Harvesting Performance on Wettability-Controlled Wire Array with Staggered Arrangement en-subtitle= kn-subtitle= en-abstract= kn-abstract=Development of freshwater resources is vital to overcoming severe worldwide water scarcity. Fog harvesting has attracted attention as a candidate technology that can be used to obtain fresh water from a stream of foggy air without energy input. Drainage of captured droplets from fog harvesters is necessary to maintain the permeability of harp-shaped harvesters. In the present study, we investigated the effect of the droplet-removal process on the amount of water harvested using a harvester constructed by wettability-controlled wires with an alternating and staggered arrangement. Droplet transfer from hydrophobic to hydrophilic wires, located upstream and downstream of the fog flow, respectively, was observed with a fog velocity greater than 1.5 m/s. The proportion of harvesting resulting from droplet transfer exceeded 30% of the total, and it reflected more than 20% increase of the harvesting performance compared with that of a harvester with wires of the same wettability: this value varied with the adhesive property of the wires and fog velocity. Scaled-up and multilayered harvesters were developed to enhance harvesting performance. We demonstrated certain enhancements under multilayered conditions and obtained 15.99 g/30 min as the maximum harvested amount, which corresponds to 13.3% of the liquid contained in the fog stream and is enhanced by 10% compared with that without droplet transfer. en-copyright= kn-copyright= en-aut-name=YamadaYutaka en-aut-sei=Yamada en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkaJunya en-aut-sei=Oka en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IsobeKazuma en-aut-sei=Isobe en-aut-mei=Kazuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HoribeAkihiko en-aut-sei=Horibe en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=32 article-no= start-page=12686 end-page=12694 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240710 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Boosting charge separation in organic photovoltaics: unveiling dipole moment variations in excited non-fullerene acceptor layers en-subtitle= kn-subtitle= en-abstract= kn-abstract=The power conversion efficiency (PCE) of organic photovoltaics (OPVs) has reached more than 19% due to the rapid development of non-fullerene acceptors (NFAs). To compete with the PCEs (26%) of commercialized silicon-based inorganic photovoltaics, the drawback of OPVs should be minimized. This drawback is the intrinsic large loss of open-circuit voltage; however, a general approach to this issue remains elusive. Here, we report a discovery regarding highly efficient NFAs, specifically ITIC. We found that charge-transfer (CT) and charge dissociation (CD) can occur even in a neat ITIC film without the donor layer. This is surprising, as these processes were previously believed to take place exclusively at donor/acceptor heterojunctions. Femtosecond time-resolved visible to mid-infrared measurements revealed that in the neat ITIC layers, the intermolecular CT immediately proceeds after photoirradiation (<0.1 ps) to form weakly-bound excitons with a binding energy of 0.3 eV, which are further dissociated into free electrons and holes with a time-constant of 56 ps. Theoretical calculations indicate that stacking faults in ITIC (i.e., V-type molecular stacking) induce instantaneous intermolecular CT and CD in the neat ITIC layer. In contrast, J-type stacking does not support such CT and CD. This previously unknown pathway is triggered by the larger dipole moment change on the excited state generated at the lower symmetric V-type molecular stacking of ITIC. This is in sharp contrast with the need of sufficient energy offset for CT and CD at the donor-acceptor heterojunction, leading to the significant voltage loss in conventional OPVs. These results demonstrate that the rational molecular design of NFAs can increase the local dipole moment change on the excited state within the NFA layer. This finding paves the way for a groundbreaking route toward the commercialization of OPVs. en-copyright= kn-copyright= en-aut-name=YamakataAkira en-aut-sei=Yamakata en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatoKosaku en-aut-sei=Kato en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UrakamiTakumi en-aut-sei=Urakami en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsujimuraSota en-aut-sei=Tsujimura en-aut-mei=Sota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurayamaKasumi en-aut-sei=Murayama en-aut-mei=Kasumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HigashiMasahiro en-aut-sei=Higashi en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SatoHirofumi en-aut-sei=Sato en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KoboriYasuhiro en-aut-sei=Kobori en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UmeyamaTomokazu en-aut-sei=Umeyama en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ImahoriHiroshi en-aut-sei=Imahori en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=Department of Molecular Engineering, Graduate School of Engineering, Kyoto University kn-affil= affil-num=4 en-affil=Department of Chemistry, Graduate School of Science, Kobe University kn-affil= affil-num=5 en-affil=Department of Chemistry, Graduate School of Science, Kobe University kn-affil= affil-num=6 en-affil=Department of Complex Systems Science, Graduate School of Informatics, Nagoya University kn-affil= affil-num=7 en-affil=Department of Molecular Engineering, Graduate School of Engineering, Kyoto University kn-affil= affil-num=8 en-affil=Department of Chemistry, Graduate School of Science, Kobe University kn-affil= affil-num=9 en-affil=Department of Applied Chemistry, Graduate School of Engineering, University of Hyogo kn-affil= affil-num=10 en-affil=Department of Molecular Engineering, Graduate School of Engineering, Kyoto University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue= article-no= start-page=1560 end-page=1571 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240711 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electrocatalytic hydrogenation of cyanoarenes, nitroarenes, quinolines, and pyridines under mild conditions with a proton-exchange membrane reactor en-subtitle= kn-subtitle= en-abstract= kn-abstract=An electrocatalytic hydrogenation of cyanoarenes, nitroarenes, quinolines, and pyridines using a proton-exchange membrane (PEM) reactor was developed.

Montmorillonite is the major clay mineral component of bentonite. Even previous studies provide few mechanical and thermodynamic data on Ca-montmorillonite. In this study, thermodynamic data on Ca-montmorillonite were obtained as a function of water content by measuring relative humidity (RH) and temperature. The activities of water and the relative partial molar Gibbs free energies of water were determined from the experimental results, and the swelling stress of Ca-bentonite was calculated using the thermodynamic model and compared with measured data. The activities of water and the relative partial molar Gibbs free energies obtained in the experiments decreased with decreasing water content in water contents lower than about 25%. This trend was similar to that of Na-montmorillonite. The swelling stress calculated based on the thermodynamic model was approximately 200 MPa at a montmorillonite partial density of 2.0 Mg/m3 and approximately 10 MPa at a montmorillonite partial density of 1.4 Mg/m3. The swelling stresses in the high-density region (around 2.0 Mg/m3) were higher than that of Na-montmorillonite and were similar levels in the low-density region (around 1.5 Mg/m3). Comparison with measured data showed the practicality of the thermodynamic model. en-copyright= kn-copyright= en-aut-name=IchikawaKosuke en-aut-sei=Ichikawa en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoHaruo en-aut-sei=Sato en-aut-mei=Haruo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=geological disposal kn-keyword=geological disposal en-keyword=buffer material kn-keyword=buffer material en-keyword=Ca-montmorillonite kn-keyword=Ca-montmorillonite en-keyword=bentonite kn-keyword=bentonite en-keyword=swelling stress kn-keyword=swelling stress 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=20240325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=包括型洪水氾濫解析を用いた防災・減災に向けた数値解析技術の開発と現地適用 kn-title=Development of numerical technique and field application using integrated simulation of river flooding and inundation for disaster prevention and mitigation en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HUAWEIJIAN en-aut-sei=HUA en-aut-mei=WEIJIAN kn-aut-name=華威鑒 kn-aut-sei=華 kn-aut-mei=威鑒 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=4 article-no= start-page=430 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240421 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Swelling Stress of Bentonite: Thermodynamics of Interlayer Water in K-Montmorillonite in Consideration of Alteration en-subtitle= kn-subtitle= en-abstract= kn-abstract=The buffer material that makes up the geological disposal system of high-level waste swells by contact with groundwater and seals space with rock mass and fractures in rock mass. The buffer material has a function of mechanical buffer with rock pressure, and swelling stress is important in this case. The alteration of bentonite may occur due to the initial replacement of cations (Na+ ions) in the interlayer with K+ ions upon contact with groundwater, but there are no studies on the swelling stress of K-bentonite. In this study, the author prepared K-montmorillonite samples and obtained thermodynamic data on interlayer water as a function of water content using a relative humidity method. The swelling stress was analyzed based on a thermodynamic model developed in earlier studies and compared with measured data. The activity and the relative partial molar Gibbs free energy of porewater decreased with decreasing water content in the region, below approximately 15%. This behavior significantly differs from that of other ions, such as Na. The swelling stress calculated based on the thermodynamic model and date occurred in the region of high density of 1.9 Mg/m3 with montmorillonite partial density. It was indicated for the first time that K-bentonite scarcely swells under realistic design conditions. en-copyright= kn-copyright= en-aut-name=EndoMisato en-aut-sei=Endo en-aut-mei=Misato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoHaruo en-aut-sei=Sato en-aut-mei=Haruo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Institute of Academic and Research, Okayama University kn-affil= en-keyword=swelling stress kn-keyword=swelling stress en-keyword=K-montmorillonite kn-keyword=K-montmorillonite en-keyword=thermodynamic data kn-keyword=thermodynamic data en-keyword=interlayer water kn-keyword=interlayer water en-keyword=relative humidity method kn-keyword=relative humidity method END start-ver=1.4 cd-journal=joma no-vol=358 cd-vols= no-issue= article-no= start-page=142060 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202406 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Size, polyglycerol grafting, and net surface charge of iron oxide nanoparticles determine their interaction and toxicity in Caenorhabditis elegans en-subtitle= kn-subtitle= en-abstract= kn-abstract=The widespread application of engineered nanoparticles (NPs) in environmental remediation has raised public concerns about their toxicity to aquatic organisms. Although appropriate surface modification can mitigate the ecotoxicity of NPs, the lack of polymer coating to inhibit toxicity completely and the insufficient knowledge about charge effect hinder the development of safe nanomaterials. Herein, we explored the potential of polyglycerol (PG) functionalization in alleviating the environmental risks of NPs. Iron oxide NPs (ION) of 20, 100, and 200 nm sizes (IONS, IONM and IONL, respectively) were grafted with PG to afford ION-PG. We examined the interaction of ION and ION-PG with Caenorhabditis elegans (C. elegans) and found that PG suppressed non-specific interaction of ION with C. elegans to reduce their accumulation and to inhibit their translocation. Particularly, IONS-PG was completely excluded from worms of all developmental stages. By covalently introducing sulfate, carboxyl and amino groups onto IONS-PG, we further demonstrated that positively charged IONS-PG-NH3+ induced high intestinal accumulation, cuticle adhesion and distal translocation, whereas the negatively charged IONS-PG-OSO3? and IONS-PG-COO? were excreted out. Consequently, no apparent deleterious effects on brood size and life span were observed in worms treated by IONS-PG and IONS-PG bearing negatively charged groups. This study presents new surface functionalization approaches for developing ecofriendly nanomaterials. 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=ShikanoYutaka en-aut-sei=Shikano en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KomatsuNaoki en-aut-sei=Komatsu en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Kage-NakadaiEriko en-aut-sei=Kage-Nakadai en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Institute of Systems and Information Engineering, University of Tsukuba 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 Human and Environmental Studies, Kyoto University kn-affil= affil-num=5 en-affil=Department of Nutrition, Graduate School of Human Life and Ecology, Osaka Metropolitan University kn-affil= affil-num=6 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=iron oxide nanoparticles kn-keyword=iron oxide nanoparticles en-keyword=polyglycerol functionalization kn-keyword=polyglycerol functionalization en-keyword=C. elegans kn-keyword=C. elegans en-keyword=accumulation kn-keyword=accumulation en-keyword=distribution kn-keyword=distribution en-keyword=toxicity kn-keyword=toxicity END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=95 end-page=106 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Roles of Neuropeptide Y in Respiratory Disease Pathogenesis via the Airway Immune Response en-subtitle= kn-subtitle= en-abstract= kn-abstract=The lungs are very complex organs, and the respiratory system performs the dual roles of repairing tissue while protecting against infection from various environmental stimuli. Persistent external irritation disrupts the immune responses of tissues and cells in the respiratory system, ultimately leading to respiratory disease. Neuropeptide Y (NPY) is a 36-amino-acid polypeptide and a neurotransmitter that regulates homeostasis. The NPY receptor is a seven-transmembrane-domain G-protein-coupled receptor with six subtypes (Y1, Y2, Y3, Y4, Y5, and Y6). Of these receptors, Y1, Y2, Y4, and Y5 are functional in humans, and Y1 plays important roles in the immune responses of many organs, including the respiratory system. NPY and the Y1 receptor have critical roles in the pathogenesis of asthma, chronic obstructive pulmonary disease, and idiopathic pulmonary fibrosis. The effects of NPY on the airway immune response and pathogenesis differ among respiratory diseases. This review focuses on the involvement of NPY in the airway immune response and pathogenesis of various respiratory diseases. en-copyright= kn-copyright= en-aut-name=ItanoJunko en-aut-sei=Itano en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KiuraKatsuyuki en-aut-sei=Kiura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=MiyaharaNobuaki en-aut-sei=Miyahara en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= en-keyword=neuropeptide y kn-keyword=neuropeptide y en-keyword=Y1 receptor kn-keyword=Y1 receptor en-keyword=airway immune response kn-keyword=airway immune response en-keyword=bronchial epithelial cells kn-keyword=bronchial epithelial cells en-keyword=respiratory disease kn-keyword=respiratory disease END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=11 article-no= start-page=1323 end-page=1330 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230524 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Transcriptomic Interpretation on?Explainable AI-Guided Intuition Uncovers Premonitory Reactions of?Disordering Fate in?Persimmon Fruit en-subtitle= kn-subtitle= en-abstract= kn-abstract=Deep neural network (DNN) techniques, as an advanced machine learning framework, have allowed various image diagnoses in plants, which often achieve better prediction performance than human experts in each specific field. Notwithstanding, in plant biology, the application of DNNs is still mostly limited to rapid and effective phenotyping. The recent development of explainable CNN frameworks has allowed visualization of the features in the prediction by a convolutional neural network (CNN), which potentially contributes to the understanding of physiological mechanisms in objective phenotypes. In this study, we propose an integration of explainable CNN and transcriptomic approach to make a physiological interpretation of a fruit internal disorder in persimmon, rapid over-softening. We constructed CNN models to accurately predict the fate to be rapid softening in persimmon cv. Soshu, only with photo images. The explainable CNNs, such as Gradient-weighted Class Activation Mapping (Grad-Class Activation Mapping (CAM)) and guided Grad-CAM, visualized specific featured regions relevant to the prediction of rapid softening, which would correspond to the premonitory symptoms in a fruit. Transcriptomic analyses to compare the featured regions of the predicted rapid-softening and control fruits suggested that rapid softening is triggered by precocious ethylene signal?dependent cell wall modification, despite exhibiting no direct phenotypic changes. Further transcriptomic comparison between the featured and non-featured regions in the predicted rapid-softening fruit suggested that premonitory symptoms reflected hypoxia and the related stress signals finally to induce ethylene signals. These results would provide a good example for the collaboration of image analysis and omics approaches in plant physiology, which uncovered a novel aspect of fruit premonitory reactions in the rapid-softening fate. en-copyright= kn-copyright= en-aut-name=MasudaKanae en-aut-sei=Masuda en-aut-mei=Kanae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuwadaEriko en-aut-sei=Kuwada en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SuzukiMaria en-aut-sei=Suzuki en-aut-mei=Maria kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuzukiTetsuya en-aut-sei=Suzuki en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NiikawaTakeshi en-aut-sei=Niikawa en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UchidaSeiichi en-aut-sei=Uchida en-aut-mei=Seiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AkagiTakashi en-aut-sei=Akagi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Gifu Prefectural Agricultural Technology Center kn-affil= affil-num=5 en-affil=Gifu Prefectural Agricultural Technology Center kn-affil= affil-num=6 en-affil=Faculty of Information Science and Electrical Engineering, Kyusyu University kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Artificial intelligence kn-keyword=Artificial intelligence en-keyword=Backpropagation kn-keyword=Backpropagation en-keyword=Convolutional neural network kn-keyword=Convolutional neural network en-keyword=Image diagnosis kn-keyword=Image diagnosis en-keyword=Physiological disorder kn-keyword=Physiological disorder END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=3 article-no= start-page=153 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240309 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Survey of AI Techniques in IoT Applications with Use Case Investigations in the Smart Environmental Monitoring and Analytics in Real-Time IoT Platform en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this paper, we have developed the SEMAR (Smart Environmental Monitoring and Analytics in Real-Time) IoT application server platform for fast deployments of IoT application systems. It provides various integration capabilities for the collection, display, and analysis of sensor data on a single platform. Recently, Artificial Intelligence (AI) has become very popular and widely used in various applications including IoT. To support this growth, the integration of AI into SEMAR is essential to enhance its capabilities after identifying the current trends of applicable AI technologies in IoT applications. In this paper, we first provide a comprehensive review of IoT applications using AI techniques in the literature. They cover predictive analytics, image classification, object detection, text spotting, auditory perception, Natural Language Processing (NLP), and collaborative AI. Next, we identify the characteristics of each technique by considering the key parameters, such as software requirements, input/output (I/O) data types, processing methods, and computations. Third, we design the integration of AI techniques into SEMAR based on the findings. Finally, we discuss use cases of SEMAR for IoT applications with AI techniques. The implementation of the proposed design in SEMAR and its use to IoT applications will be in future works. 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=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=FajriantiEvianita Dewi en-aut-sei=Fajrianti en-aut-mei=Evianita Dewi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=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=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Department of Informatic and Computer, Politeknik Elektronika Negeri Surabaya kn-affil= en-keyword=Internet of Things kn-keyword=Internet of Things en-keyword=AI kn-keyword=AI en-keyword=integration kn-keyword=integration en-keyword=survey kn-keyword=survey en-keyword=application server platform kn-keyword=application server platform en-keyword=SEMAR kn-keyword=SEMAR END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=33 end-page=46 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240329 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The Role of Teachers in the Development of Play Using Grasses and Flowers in a Kindergarten Class for 4-year-olds kn-title=幼稚園4歳児学級における草花を使った遊びの展開に見る教師の役割 en-subtitle= kn-subtitle= en-abstract=This paper aims to organize and examine the role of teachers in the play using grasses and flowers in a kindergarten class for 4-year-olds.

However, how dwarf bamboos respond to and exploit these phenological gaps remain enigmatic. The light environment, soil nutrients, leaf morphology, maximum photosynthetic rate, foliage dynamics, and branching characteristics of Sasa kurilensis were examined under the canopies of Fagus crenata and Magnolia obovata. The goal was to elucidate the adaptive responses of S. kurilensis to phenological gaps in the forest understory. The findings suggest that phenological gaps under an M. obovata canopy augment the available biomass of S. kurilensis, enhancing leaf area, leaf thickness, and carbon content per unit area. However, these gaps do not appreciably influence the maximum photosynthetic rate, total leaf number, leaf lifespan, branch number, and average branch length. These findings underscore the significant impact of annually recurring phenological gaps on various aspects of S. kurilensis growth, such as its aboveground biomass, leaf morphology, and leaf biochemical characteristics. It appears that leaf morphology is a pivotal trait in the response of S. kurilensis to phenological gaps. Given the potential ubiquity of the influence of phenological gaps on dwarf bamboos across most deciduous broadleaf forests, this canopy phenomenon should not be overlooked. en-copyright= kn-copyright= en-aut-name=WuChongyang en-aut-sei=Wu en-aut-mei=Chongyang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaRyota en-aut-sei=Tanaka en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiyoshiKyohei en-aut-sei=Fujiyoshi en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AkajiYasuaki en-aut-sei=Akaji en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HirobeMuneto en-aut-sei=Hirobe en-aut-mei=Muneto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MikiNaoko en-aut-sei=Miki en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=LiJuan en-aut-sei=Li en-aut-mei=Juan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SakamotoKeiji en-aut-sei=Sakamoto en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=GaoJian en-aut-sei=Gao en-aut-mei=Jian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Beijing for Bamboo & Rattan Science and Technology/International Centre for Bamboo and Rattan, Key Laboratory of National Forestry and Grassland Administration kn-affil= affil-num=2 en-affil=Faculty of Agriculture, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Agriculture, Okayama University kn-affil= affil-num=4 en-affil=Biodiversity Division, National Institute for Environmental Studies kn-affil= affil-num=5 en-affil=Department of Environmental Ecology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Department of Environmental Ecology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Beijing for Bamboo & Rattan Science and Technology/International Centre for Bamboo and Rattan, Key Laboratory of National Forestry and Grassland Administration kn-affil= affil-num=8 en-affil=Department of Environmental Ecology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=9 en-affil=Beijing for Bamboo & Rattan Science and Technology/International Centre for Bamboo and Rattan, Key Laboratory of National Forestry and Grassland Administration kn-affil= en-keyword=bamboo kn-keyword=bamboo en-keyword=sasa kn-keyword=sasa en-keyword=beech forest kn-keyword=beech forest en-keyword=phenological gap kn-keyword=phenological gap en-keyword=canopy kn-keyword=canopy en-keyword=understory plant kn-keyword=understory plant en-keyword=plant morphology kn-keyword=plant morphology en-keyword=plastically kn-keyword=plastically en-keyword=leaf phenology kn-keyword=leaf phenology END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=2 article-no= start-page=281 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240116 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A System for Monitoring Animals Based on Behavioral Information and Internal State Information en-subtitle= kn-subtitle= en-abstract= kn-abstract=Managing the risk of injury or illness is an important consideration when keeping pets. This risk can be minimized if pets are monitored on a regular basis, but this can be difficult and time-consuming. However, because only the external behavior of the animal can be observed and the internal condition cannot be assessed, the animal’s state can easily be misjudged. Additionally, although some systems use heartbeat measurement to determine a state of tension, or use rest to assess the internal state, because an increase in heart rate can also occur as a result of exercise, it is desirable to use this measurement in combination with behavioral information. In the current study, we proposed a monitoring system for animals using video image analysis. The proposed system first extracts features related to behavioral information and the animal’s internal state via mask R-CNN using video images taken from the top of the cage. These features are used to detect typical daily activities and anomalous activities. This method produces an alert when the hamster behaves in an unusual way. In our experiment, the daily behavior of a hamster was measured and analyzed using the proposed system. The results showed that the features of the hamster’s behavior were successfully detected. When loud sounds were presented from outside the cage, the system was able to discriminate between the behavioral and internal changes of the hamster. In future research, we plan to improve the accuracy of the measurement of small movements and develop a more accurate system. en-copyright= kn-copyright= en-aut-name=ShibanokiTaro en-aut-sei=Shibanoki en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamazakiYuugo en-aut-sei=Yamazaki en-aut-mei=Yuugo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TonookaHideyuki en-aut-sei=Tonooka en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Intelligent Mechanical Systems, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Major in Computer and Information Sciences, Graduate School of Science and Engineering, Ibaraki University kn-affil= affil-num=3 en-affil=Major in Computer and Information Sciences, Graduate School of Science and Engineering, Ibaraki University kn-affil= en-keyword=monitoring system kn-keyword=monitoring system en-keyword=image processing kn-keyword=image processing en-keyword=mask R-CNN kn-keyword=mask R-CNN en-keyword=anomaly detection kn-keyword=anomaly detection en-keyword=one-class SVM kn-keyword=one-class SVM en-keyword=rodents kn-keyword=rodents END start-ver=1.4 cd-journal=joma no-vol=113 cd-vols= no-issue= article-no= start-page=7 end-page=10 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of seed cold PEG-priming and subsequent long storage on germination, growth and flowering of Eustoma grandiflorum(Raf.)Shinn ?Exe Lavender? en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cold wet treatment is frequently applied to Eustoma seeds to enhance the bolting rate of plants grown under high temperatures. Our previous study indicated that cold PEG?primed Eustoma seeds could maintain their germination rate and bolting rate even after being re?dried for 30days and grown under high temperatures. The present study aimed to investigate whether prolonged storage after cold PEG?priming affect the germination, growth, and flowering of Eustoma ‘Exe Lavender’ seedling. Seeds were initially cold?primed with water or PEG?6000 at ?1.5 MPa for 5 weeks at 10°C in the dark and were then subjected to re?drying and storage for 30, 60, 90 and 360days at 10°C. After 360days of storage, cold PEG?primed seeds germinated earlier and more effectively than cold hydro?primed seeds. Compared to the results after 30days of storage, plants grown from 360days exhibited similar bolting rate, days to bolting, bolting node and flowering rate, cut flower length and number of flower node. These results suggest that ‘Exe Lavender’ seeds can germinate and develop well even after 360days of storage and under high temperature conditions when subjected to cold PEG?6000 treatment. en-copyright= kn-copyright= en-aut-name=PhanThao Thu en-aut-sei=Phan en-aut-mei=Thao Thu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukushimaKeigo en-aut-sei=Fukushima en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaYoshiyuki en-aut-sei=Tanaka en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasubaKen-ichiro en-aut-sei=Yasuba en-aut-mei=Ken-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshidaYuichi en-aut-sei=Yoshida en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GotoTanjuro en-aut-sei=Goto en-aut-mei=Tanjuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Hiroshima Prefectural Technology Research Institute, Agricultural Technology Research Center kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=bolting kn-keyword=bolting en-keyword=chilling kn-keyword=chilling en-keyword=dehydrate kn-keyword=dehydrate en-keyword=long storage kn-keyword=long storage en-keyword=PEG-6000 kn-keyword=PEG-6000 END start-ver=1.4 cd-journal=joma no-vol=221 cd-vols= no-issue= article-no= start-page=125047 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bayesian optimization of periodic multilayered slabs for passive absorptivity control en-subtitle= kn-subtitle= en-abstract= kn-abstract=A vanadium dioxide (VO2) film grown on a titanium oxide crystal shows a metal?insulator transition at room temperature with drastically changed optical properties. A multilayered slab with a sub-micron scale VO2 film was proposed to utilize its unique properties for passive intensity control of sunlight absorption and radiative cooling. Its optimal geometries were numerically explored using the Bayesian optimization (BO) method. BO was applied for three types of multilayered slabs, those having one, two, or three isolated slabs of different widths. For each type of multilayered slab, BO could optimize geometric variables with practical calculation times considering the total number of possible combinations of variables, which is subsequently referred to as the total number of candidates. Optimization results revealed that two isolated slabs had the most suitable spectral absorptivity in both hot and cold environments. The infrared absorptivity of the double slab was kept low in cold conditions to suppress radiative cooling. However, the double slab exhibited good radiative cooling performance under hot conditions. Electromagnetic energy density surrounding the slab illustrated that metallic VO2 and gold placed in a parallel manner excited the coupled mode of surface plasmon polaritons to enhance absorptivity. Radiative cooling faded for the triple slab because each slab could couple with radiation propagating only across a portion of the cross-sectional area. Through three BO trials, improvement of the VO2 visible reflectivity was recognized as a future issue for further development of passive sunlight absorption control. en-copyright= kn-copyright= en-aut-name=IsobeKazuma en-aut-sei=Isobe en-aut-mei=Kazuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoTsuyoshi en-aut-sei=Yamamoto en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=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=Department of Advanced Mechanics, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Advanced Mechanics, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Advanced Mechanics, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Advanced Mechanics, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Radiative cooling kn-keyword=Radiative cooling en-keyword=Sunlight absorption kn-keyword=Sunlight absorption en-keyword=Bayesian optimization kn-keyword=Bayesian optimization en-keyword=Vanadium dioxide kn-keyword=Vanadium dioxide en-keyword=Short-range surface plasmon polariton kn-keyword=Short-range surface plasmon polariton END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=7 article-no= start-page=100873 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202307 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of liquefied sake lees on growth performance and faecal and blood characteristics in Japanese Black calves en-subtitle= kn-subtitle= en-abstract= kn-abstract=Liquefied sake lees, a by-product of Japanese sake, is rich in Saccharomyces cerevisiae, proteins, and prebiotics derived from rice and yeast. Previous studies have reported that Saccharomyces cerevisiae fermentation products improved the health, growth, and faecal characteristics of preweaning calves. This study investigated the effects of adding liquefied sake lees to milk replacer on the growth performance, faecal characteristics, and blood metabolites of preweaning Japanese Black calves from 6 to 90 days of age. Twenty-four Japanese Black calves at 6 days of age were randomly assigned to one of three treatments: No liquefied sake lees (C, n = 8), 100 g/d (on a fresh matter basis) liquefied sake lees mixed with milk replacer (LS, n = 8), and 200 g/d (on a fresh matter basis) liquefied sake lees mixed with milk replacer (HS, n = 8). The intake of milk replacer and calf starter, as well as, the average daily gain did not differ between the treatments. The number of days counted with faecal score 1 in LS was higher than in HS (P < 0.05), while the number of days with diarrhoea medication in LS and C was lower than HS (P < 0.05). The faecal n-butyric acid concentration tended to be higher in LS compared to C (P = 0.060). The alpha diversity index (Chao1) was higher in HS than in C and LS at 90 days of age (P < 0.05). The principal coordinate analysis (PCoA) using weighted UniFrac distance showed that the bacterial community structures in faeces among the treatments at 90 days of age were significantly different (P < 0.05). The plasma β-hydroxybutyric acid concentration, an indicator of rumen development, was higher for LS than in C throughout the experiment (P < 0.05). These results suggested that adding liquefied sake lees up to 100 g/d (on a fresh matter basis) might promote rumen development in preweaning Japanese Black calves. en-copyright= kn-copyright= en-aut-name=KatsumataS. en-aut-sei=Katsumata en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayashiY. en-aut-sei=Hayashi en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OishiK. en-aut-sei=Oishi en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsukaharaT. en-aut-sei=Tsukahara en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=InoueR. en-aut-sei=Inoue en-aut-mei=R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ObataA. en-aut-sei=Obata en-aut-mei=A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HirookaH. en-aut-sei=Hirooka en-aut-mei=H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KumagaiH. en-aut-sei=Kumagai en-aut-mei=H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Shiga Prefectural Livestock Production Technology Promotion Center kn-affil= affil-num=3 en-affil=Department of Applied Biosciences, Graduate School of Agriculture, Kyoto University kn-affil= affil-num=4 en-affil=Kyoto Institute of Nutrition and Pathology kn-affil= affil-num=5 en-affil=Department of Applied Biological Sciences, Faculty of Agriculture, Setsunan University kn-affil= affil-num=6 en-affil=Shiga Prefectural Livestock Production Technology Promotion Center kn-affil= affil-num=7 en-affil=Department of Applied Biosciences, Graduate School of Agriculture, Kyoto University kn-affil= affil-num=8 en-affil=Department of Applied Biosciences, Graduate School of Agriculture, Kyoto University kn-affil= en-keyword=By-products kn-keyword=By-products en-keyword=Faecal microbiota kn-keyword=Faecal microbiota en-keyword=Japanese Black cattle kn-keyword=Japanese Black cattle en-keyword=Preweaning calves kn-keyword=Preweaning calves en-keyword=Saccharomyces cerevisiae kn-keyword=Saccharomyces cerevisiae END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=0073 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230728 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Deep Learning Enables Instant and Versatile Estimation of Rice Yield Using Ground-Based RGB Images en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rice (Oryza sativa L.) is one of the most important cereals, which provides 20% of the world’s food energy. However, its productivity is poorly assessed especially in the global South. Here, we provide a first study to perform a deep-learning-based approach for instantaneously estimating rice yield using red-green-blue images. During ripening stage and at harvest, over 22,000 digital images were captured vertically downward over the rice canopy from a distance of 0.8 to 0.9 m at 4,820 harvesting plots having the yield of 0.1 to 16.1 t?ha?1 across 6 countries in Africa and Japan. A convolutional neural network applied to these data at harvest predicted 68% variation in yield with a relative root mean square error of 0.22. The developed model successfully detected genotypic difference and impact of agronomic interventions on yield in the independent dataset. The model also demonstrated robustness against the images acquired at different shooting angles up to 30° from right angle, diverse light environments, and shooting date during late ripening stage. Even when the resolution of images was reduced (from 0.2 to 3.2 cm?pixel?1 of ground sampling distance), the model could predict 57% variation in yield, implying that this approach can be scaled by the use of unmanned aerial vehicles. Our work offers low-cost, hands-on, and rapid approach for high-throughput phenotyping and can lead to impact assessment of productivity-enhancing interventions, detection of fields where these are needed to sustainably increase crop production, and yield forecast at several weeks before harvesting. en-copyright= kn-copyright= en-aut-name=TanakaYu en-aut-sei=Tanaka en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WatanabeTomoya en-aut-sei=Watanabe en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatsuraKeisuke en-aut-sei=Katsura en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsujimotoYasuhiro en-aut-sei=Tsujimoto en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakaiToshiyuki en-aut-sei=Takai en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaTakashi Sonam Tashi en-aut-sei=Tanaka en-aut-mei=Takashi Sonam Tashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawamuraKensuke en-aut-sei=Kawamura en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SaitoHiroki en-aut-sei=Saito en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HommaKoki en-aut-sei=Homma en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MairouaSalifou Goube en-aut-sei=Mairoua en-aut-mei=Salifou Goube kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AhouantonKokou en-aut-sei=Ahouanton en-aut-mei=Kokou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=IbrahimAli en-aut-sei=Ibrahim en-aut-mei=Ali kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=SenthilkumarKalimuthu en-aut-sei=Senthilkumar en-aut-mei=Kalimuthu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=SemwalVimal Kumar en-aut-sei=Semwal en-aut-mei=Vimal Kumar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=MatuteEduardo Jose Graterol en-aut-sei=Matute en-aut-mei=Eduardo Jose Graterol kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=CorredorEdgar en-aut-sei=Corredor en-aut-mei=Edgar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=El-NamakyRaafat en-aut-sei=El-Namaky en-aut-mei=Raafat kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=ManigbasNorvie en-aut-sei=Manigbas en-aut-mei=Norvie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= en-aut-name=QuilangEduardo Jimmy P. en-aut-sei=Quilang en-aut-mei=Eduardo Jimmy P. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=19 ORCID= en-aut-name=IwahashiYu en-aut-sei=Iwahashi en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=20 ORCID= en-aut-name=NakajimaKota en-aut-sei=Nakajima en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=21 ORCID= en-aut-name=TakeuchiEisuke en-aut-sei=Takeuchi en-aut-mei=Eisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=22 ORCID= en-aut-name=SaitoKazuki en-aut-sei=Saito en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=23 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 Mathematics, Kyushu University kn-affil= affil-num=3 en-affil=Graduate School of Agriculture, Tokyo University of Agriculture and Technology kn-affil= affil-num=4 en-affil=Japan International Research Center for Agricultural Sciences kn-affil= affil-num=5 en-affil=Japan International Research Center for Agricultural Sciences 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=Japan International Research Center for Agricultural Sciences kn-affil= affil-num=8 en-affil=Tropical Agriculture Research Front, Japan International Research Center for Agricultural Sciences kn-affil= affil-num=9 en-affil=Graduate School of Agricultural Science, Tohoku University kn-affil= affil-num=10 en-affil=Africa Rice Center (AfricaRice) kn-affil= affil-num=11 en-affil=Africa Rice Center (AfricaRice) kn-affil= affil-num=12 en-affil=Africa Rice Center (AfricaRice), Regional Station for the Sahel kn-affil= affil-num=13 en-affil=Africa Rice Center (AfricaRice) kn-affil= affil-num=14 en-affil=Africa Rice Center (AfricaRice), Nigeria Station kn-affil= affil-num=15 en-affil=Latin American Fund for Irrigated Rice -

Strain NIES-4635 by Multi-Pulse Electroporation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nitzschia is one of the largest genera of diatoms found in a range of aquatic environments, from freshwater to seawater. This genus contains evolutionarily and ecologically unique species, such as those that have lost photosynthetic capacity or those that live symbiotically in dinoflagellates. Several Nitzschia species have been used as indicators of water pollution. Recently, Nitzschia species have attracted considerable attention in the field of biotechnology. In this study, a transformation method for the marine pennate diatom Nitzschia sp. strain NIES-4635, isolated from the coastal Seto Inland Sea, was established. Plasmids containing the promoter/terminator of the fucoxanthin chlorophyll a/c binding protein gene (fcp, or Lhcf) derived from Nitzschia palea were constructed and introduced into cells by multi-pulse electroporation, resulting in 500 μg/mL nourseothricin-resistant transformants with transformation frequencies of up to 365 colonies per 108 cells. In addition, when transformation was performed using a new plasmid containing a promoter derived from a diatom-infecting virus upstream of the green fluorescent protein gene (gfp), 44% of the nourseothricin-resistant clones exhibited GFP fluorescence. The integration of the genes introduced into the genomes of the transformants was confirmed by Southern blotting. The Nitzschia transformation method established in this study will enable the transformation this species, thus allowing the functional analysis of genes from the genus Nitzschia, which are important species for environmental and biotechnological development. en-copyright= kn-copyright= en-aut-name=OkadaKoki en-aut-sei=Okada en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorimotoYu en-aut-sei=Morimoto en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShiraishiYukine en-aut-sei=Shiraishi en-aut-mei=Yukine kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TamuraTakashi en-aut-sei=Tamura en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MayamaShigeki en-aut-sei=Mayama en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KadonoTakashi en-aut-sei=Kadono en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AdachiMasao en-aut-sei=Adachi en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=NemotoMichiko en-aut-sei=Nemoto en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=The Advanced Support Center for Science Teachers, Tokyo Gakugei University kn-affil= affil-num=6 en-affil=Faculty of Agriculture and Marine Science, Kochi University kn-affil= affil-num=7 en-affil=Faculty of Agriculture and Marine Science, Kochi University kn-affil= affil-num=8 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=9 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Diatom kn-keyword=Diatom en-keyword=Genetic transformation kn-keyword=Genetic transformation en-keyword=Nitzschia kn-keyword=Nitzschia en-keyword=Multi-pulse electroporation kn-keyword=Multi-pulse electroporation END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=11 article-no= start-page=424 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231114 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of Hexagonal Pyramid-Shaped Flexible Actuator with Anisotropic Stiffness for Upper-Limb Rehabilitation Device en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rehabilitation devices for passive exercise have been actively researched and developed in accordance with Japan's aging society. A previous study proposed and tested an extension-type flexible pneumatic actuator (EFPA) with reinforced stiffness that could achieve passive exercise in patients. In addition, a rehabilitation device for shoulder joints with an embedded controller and small valves was proposed and tested. Joints such as the shoulder and scapula were subjected to passive exercise utilizing the tested device. However, it is difficult for patients with contractions to perform the same exercise because the reinforced EFPA can buckle. Here, to realize an EFPA with a higher stiffness, a flexible actuator in the shape of a hexagonal pyramid is proposed and tested. The hexagonal pyramid shape of a flexible actuator has a high stiffness in the direction of motion and flexibility in other directions; hereafter, this characteristic is called anisotropic stiffness. The characteristics of the hexagonal pyramid shape of the EFPA are described and compared with those of a previously reinforced EFPA. An analytical model was proposed to predict and design the shape of the hexagonal pyramid EFPA.

Steroid hormones are synthesized through the actions of steroidogenic enzymes, specifically STAR, CYP11A1, HSD3B, and CYP19A1 in both theca cells (TCs) and granulosa cells (GCs), under the influence of gonadotropins. Particularly, estradiol 17 beta (E2) assumes a central role in follicular development and selection by activating estrogen receptors beta (ESR2) in GCs. We assessed ESR2 mRNA expression in GCs of developing follicles and investigated the impact of IGF-1 on the mRNA expression of ESR2, CYP19A1, FSHR, and LHCGR, STAR, CYP11A1, and HSD17B in cultured GCs and TCs, respectively. Additionally, we assessed the influence of IGF-1 on androstenedione (A4), progesterone (P4), and testosterone (T) production in TCs. Small-sized follicles (< 6 mm) exhibited the highest levels of ESR2 mRNA expression, whereas medium-sized follicles (7-8 mm) displayed higher levels than large-sized follicles (>= 9 mm) (P < 0.05). IGF-1 increased the mRNA expression of ESR2, CYP19A1, and FSHR in GCs of follicles of both sizes, except for FSHR mRNA in medium-sized follicles (P < 0.05). IGF-1 significantly elevated mRNA expression of LHCGR, STAR, CYP11A1, and CYP17B in TCs of small-and medium-sized follicles (P < 0.05). Moreover, IGF-1 augmented the production of A4 and P4 but had no impact on T production in TCs of small-and medium-sized follicles. Taken together, our findings indicate that IGF-1 upregulates steroidogenic enzymes and steroid hormone production, underscoring the crucial role of IGF-1 in follicle development and selection. en-copyright= kn-copyright= en-aut-name=RawanAhmad Farid en-aut-sei=Rawan en-aut-mei=Ahmad Farid kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LangarHikmatullah en-aut-sei=Langar en-aut-mei=Hikmatullah kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MunetomoMaho en-aut-sei=Munetomo en-aut-mei=Maho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoYuki en-aut-sei=Yamamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawanoKohei en-aut-sei=Kawano en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KimuraKoji en-aut-sei=Kimura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Laboratory of Reproductive Physiology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Reproductive Physiology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Reproductive Physiology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Laboratory of Reproductive Physiology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Laboratory of Reproductive Physiology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Laboratory of Reproductive Physiology, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Estradiol receptor kn-keyword=Estradiol receptor en-keyword=Follicle kn-keyword=Follicle en-keyword=Insulin-like growth factor-1 (IGF-1) kn-keyword=Insulin-like growth factor-1 (IGF-1) en-keyword=Steroidogenic enzymes kn-keyword=Steroidogenic enzymes END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=20 article-no= start-page=15450 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231022 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Roles of Oxidative Injury and Nitric Oxide System Derangements in Kawasaki Disease Pathogenesis: A Systematic Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Kawasaki disease (KD) is an acute febrile vasculitis that occurs mostly in children younger than five years. KD involves multiple intricately connected inflammatory reactions activated by a cytokine cascade. Despite therapeutic advances, coronary artery damage may develop in some patients, who will be at risk of clinical cardiovascular events and even sudden death. The etiology of KD remains unclear; however, it may involve both genetic and environmental factors leading to aberrant inflammatory responses. Given the young age of onset, prenatal or perinatal exposure may be etiologically relevant. Multisystem inflammatory syndrome in children, a post-infectious hyper-inflammatory disorder associated with severe acute respiratory syndrome coronavirus 2, has features that overlap with those of KD. Available evidence indicates that vascular endothelial dysfunction is a critical step in the sequence of events leading to the development of cardiovascular lesions in KD. Oxidative stress and the dysregulation of the nitric oxide (NO) system contribute to the pathogenesis of inflammatory responses related to this disease. This review provides current evidence and concepts highlighting the adverse effects of oxidative injury and NO system derangements on the initiation and progression of KD and potential therapeutic strategies for cardiovascular pathologies in affected children. en-copyright= kn-copyright= en-aut-name=TsugeMitsuru en-aut-sei=Tsuge en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UdaKazuhiro en-aut-sei=Uda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EitokuTakahiro en-aut-sei=Eitoku en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pediatrics, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of Epidemiology, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Epidemiology, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=biomarker kn-keyword=biomarker en-keyword=coronary artery lesions kn-keyword=coronary artery lesions en-keyword=Kawasaki disease kn-keyword=Kawasaki disease en-keyword=multisystem inflammatory syndrome in children kn-keyword=multisystem inflammatory syndrome in children en-keyword=nitric oxide kn-keyword=nitric oxide en-keyword=nitrosative stress kn-keyword=nitrosative stress en-keyword=oxidative stress kn-keyword=oxidative stress en-keyword=systemic inflammation kn-keyword=systemic inflammation en-keyword=vascular endothelial dysfunction kn-keyword=vascular endothelial dysfunction END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=20 article-no= start-page=11308 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231014 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evolutionary-Game-Theory-Based Epidemiological Model for Prediction of Infections with Application to Demand Forecasting in Pharmaceutical Inventory Management Problems en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pharmaceuticals play a critical role in the eradication of infectious diseases. Effective pharmaceutical inventory management is important for controlling epidemics since medical resources such as pharmaceuticals, medical staff, and hospitals are limited. In this study, a novel epidemiological model is proposed to evaluate the resource requirements for pharmaceuticals and is applied to analyze different pharmaceutical inventory management strategies. We formulate the relationship between the number of infected individuals and the risk of infection to account for virus mutation. Evolutionary game theory is integrated into an epidemiological model to represent human behavioral choices. The proposed model can be developed to forecast the demand for pharmaceuticals and analyze how human behavior affects the demand of pharmaceuticals. This study found that making people aware of the risk of disease has a positive impact on both reducing the number of infections and managing the pharmaceutical inventory. The main contribution of this study is to enhance areas of research in pharmaceutical inventory management. This study revealed that the correct recognition of the risk of disease leads to appropriate pharmaceutical management. There are a few studies on the application of infectious disease models to inventory control problems. This study provides clues toward proper pharmaceutical management. en-copyright= kn-copyright= en-aut-name=NishihataYu en-aut-sei=Nishihata en-aut-mei=Yu 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=inventory management kn-keyword=inventory management en-keyword=SEIR model kn-keyword=SEIR model en-keyword=evolutionary game theory kn-keyword=evolutionary game theory END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=5 article-no= start-page=054107 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231016 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Diamond quantum sensors in microfluidics technology en-subtitle= kn-subtitle= en-abstract= kn-abstract=Diamond quantum sensing is an emerging technology for probing multiple physico-chemical parameters in the nano- to micro-scale dimensions within diverse chemical and biological contexts.

The photoinduced cytosolic dispersion of RNA (PCDR) method that we previously reported can introduce small RNAs into the cytosol of photoirradiated cells and enable RNA delivery into a single-cell in a spatiotemporally specific manner. However, the PCDR method has only been applied to planer cultured cells and not to embryos. This study demonstrated that the PCDR method can be utilized for photo-dependent cytosolic shRNA delivery into a single blastomere and for single blastomere-specific RNA interference in mouse embryos. Our results indicate that PCDR is a promising approach for studying the developmental process of early embryogenesis. en-copyright= kn-copyright= en-aut-name=IkawaYuka en-aut-sei=Ikawa en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WakaiTakuya en-aut-sei=Wakai en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FunahashiHiroaki en-aut-sei=Funahashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SoeTet Htut en-aut-sei=Soe en-aut-mei=Tet Htut kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WatanabeKazunori en-aut-sei=Watanabe en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhtsukiTakashi en-aut-sei=Ohtsuki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Animal Science, Graduate of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Animal Science, Graduate of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=5 article-no= start-page=491 end-page=497 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Participation in the Setouchi Triennale and the Health of Residents in Naoshima: A Cross-Sectional Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Arts festivals have become increasingly popular in various parts of Japan in recent years. The purpose of this study was to investigate the relationships between arts festival activities participation at the Setouchi Triennale and the health of residents in the town of Naoshima. This was a cross-sectional study. Questionnaires were distributed to all residents of Naoshima who were 20 years old or older (n=2,588). We analyzed responses from 708 people. The associations between arts festival activities participation and health (measured by self-rated health) were analyzed using logistic regression analysis as the primary outcome. Kessler’s psychological distress scale scores were also analyzed in the same manner as the primary outcome. The participating group had an adjusted odds ratio of 1.86 (95% confidence interval: 1.03-3.33) for higher self-rated health compared with those who did not participate. Kessler’s psychological distress scale results showed that the participating group had an adjusted odds ratio of 3.23 (95% confidence interval: 1.19-8.81) for lower psychological distress compared with those who did not participate. In conclusion, arts festival activities participation was associated with higher self-rated health and lower psychological distress. However, caution must be taken in regard to generalizability and causality when interpreting these results. en-copyright= kn-copyright= en-aut-name=HabuHiroshi en-aut-sei=Habu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyajiChikara en-aut-sei=Miyaji en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AooKen en-aut-sei=Aoo en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishitaYosuke en-aut-sei=Nishita en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsuriMasao en-aut-sei=Tsuri en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Economics, Musashi University kn-affil= affil-num=8 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=art kn-keyword=art en-keyword=arts in public health kn-keyword=arts in public health en-keyword=arts festival kn-keyword=arts festival en-keyword=self-rated health kn-keyword=self-rated health en-keyword=Setouchi Triennale kn-keyword=Setouchi Triennale END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=5 article-no= start-page=479 end-page=490 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Childcare and Child Development in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=For decades, the notion has persisted in developed countries that exclusive care by the mothers is best for the development of children up to 3 years of age. To examine the veracity of this “myth of the first three years” in Japan, we examined the effects of childcare facility use for children younger than 3 years on their development using the cohorts of the Longitudinal Survey of Newborns in the 21st Century conducted in Japan. Of the 47,015 respondents to the survey, we studied the children of 5,508 mothers with university/professional education to evaluate the relationships between primary early (< 2.5 years) childcare providers during weekday daytime hours and specific development indices for the ages of 2.5, 5.5, and 8 years. At the age of 2.5 and 5.5 years, children attending childcare facilities were judged as having more advanced developmental behaviors by their parents, such as being able to compose a two-word sentence (adjusted odds ratio [aOR]: 0.22) or to express emotions (aOR: 0.81), compared with those cared for by mothers. However, at the age of 8 years, children who attended childcare facilities as infants < 2.5 years showed more aggressive behavior in interrupting people (aOR: 1.20) and causing disturbances in public (aOR: 1.26) than those cared for by mothers (after adjustment for numerous child and parental factors). Although these results are generally consistent with previous studies, issues potentially involved with problem behavior such as quality of childcare require further investigation, as does the case of children of mothers with more modest educational attainment. en-copyright= kn-copyright= en-aut-name=MurataAkiko en-aut-sei=Murata en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyajiChikara en-aut-sei=Miyaji en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=“myth of the first three years” kn-keyword=“myth of the first three years” en-keyword=childcare kn-keyword=childcare en-keyword=child development kn-keyword=child development en-keyword=problem behavior kn-keyword=problem behavior en-keyword=educational attainment kn-keyword=educational attainment END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=5 article-no= start-page=443 end-page=449 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Does Participation in the Setouchi Triennale Foster Social Capital? : A Cross-Sectional Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study examined whether participation in an art project was associated with higher social capital (SC). We conducted a questionnaire survey from November 2021 to March 2022 among residents aged 20 years or older of Naoshima, an island in Kagawa Prefecture, Japan. Before the survey, the Setouchi Triennale had been held on Naoshima four times, starting in 2010. We calculated propensity scores for Triennale participation and performed propensity score matching. We then compared cognitive and structural SC by Triennale participation and found significant differences, respectively. We adopted a conditional ordered logistic regression analysis with propensity score matching for cognitive or structural SC, and found adjusted odd ratios of 2.913 (95%CI, 1.846-4.596) for cognitive SC and 4.535 (95%CI, 2.839-7.244) for structural SC. Our findings suggest that Triennale participation enhanced the cognitive aspect of SC while also building structural SC. en-copyright= kn-copyright= en-aut-name=MiyajiChikara en-aut-sei=Miyaji en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HabuHiroshi en-aut-sei=Habu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AooKen en-aut-sei=Aoo en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishitaYosuke en-aut-sei=Nishita en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsuriMasao en-aut-sei=Tsuri en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Economics, Musashi University kn-affil= affil-num=8 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=social capital kn-keyword=social capital en-keyword=art project kn-keyword=art project en-keyword=propensity score matching kn-keyword=propensity score matching END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=13770 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230823 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A population-based longitudinal study on glycated hemoglobin levels and new-onset chronic kidney disease among non-diabetic Japanese adults en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chronic kidney disease (CKD) is a major global public health problem. Recent studies reported that diabetes and prediabetes are risk factors for developing CKD; however, the exact glycated hemoglobin (HbA1c) cut-off value for prediabetes remains controversial. In this study, we aimed to examine the relationship between HbA1c levels and subsequent CKD development in greater detail than previous studies. Longitudinal data of annual checkups of 7176 Japanese non-diabetic people (male: 40.4%) from 1998 to 2022 was analyzed. HbA1c values were categorized into < 5.0%, 5.0-5.4%, 5.5-5.9%, and 6.0-6.4%. CKD was defined as an estimated glomerular filtration rate < 60 ml/min/1.73 m(2). The descriptive statistics at study entry showed that higher HbA1c values were associated with male, older, overweight or obese, hypertensive, or dyslipidemic people. During a mean follow-up of 7.75 person-years, 2374 participants (male: 40.0%) developed CKD. The Weibull accelerated failure time model was selected because the proportional hazards assumption was violated. The adjusted time ratios of developing CKD for HbA1c levels of 5.5-5.9% and 6.0-6.4% compared with 5.0-5.4% were 0.97 (95% confidence interval: 0.92-1.03) and 1.01 (95% confidence interval: 0.90-1.13), respectively. There was no association between HbA1c in the prediabetic range and subsequent CKD development. en-copyright= kn-copyright= en-aut-name=OkawaYukari en-aut-sei=Okawa en-aut-mei=Yukari 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= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsudaToshihide en-aut-sei=Tsuda en-aut-mei=Toshihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= affil-num=1 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Human Ecology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=134 cd-vols= no-issue=1 article-no= start-page=18 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Data-driven model of the local wind field over two small lakes in Jyv?skyl?, Finland en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study presents a data-driven model of the local wind field over two small lakes in Jyv?skyl?, Finland. Five temporary monitoring stations installed during the summers of 2015 and 2016 observed wind speed/direction around the two lakes. In addition, an official meteorological station located 15 km north of the lakes is permanently available. Our goal was to develop a model that could evaluate wind speed and direction over the two lakes using only data from the permanent station. Statistical analysis for the spatio-temporal wind data revealed that (1) local wind speed is correlated with the elevation and its cyclic pattern is identical to that of the official-station data, and (2) the local wind direction field is spatially homogeneous and is strongly correlated with the official-station data. Based on these results, we built two regression models for estimating spatial distribution of local wind speed and directions based on the digital elevation model (DEM) and official-station data. We compared the predicted wind speeds/directions by the proposed model with the corresponding observation data and a numerical result for model validation. We found that the proposed model could effectively simulate heterogeneous local wind fields and considers uncertainty of estimates. en-copyright= kn-copyright= en-aut-name=ShukuTakayuki en-aut-sei=Shuku en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=RopponenJanne en-aut-sei=Ropponen en-aut-mei=Janne kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=JuntunenJanne en-aut-sei=Juntunen en-aut-mei=Janne kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuitoHiroshi en-aut-sei=Suito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Finnish Environment Institute SYKE, Jyv?skyl?

In this study, we newly identified and characterized a rhodopsin from a thermophilic bacterium, Bellilinea sp. Recombinant Escherichia coli cells expressing the rhodopsin showed light-induced alkalization of the medium only in the presence of sodium ions (Na+), and the alkalization signal was enhanced by addition of a protonophore, indicating an outward Na+ pump function across the cellular membrane. Thus, we named the protein Bellilinea Na+-pumping rhodopsin, BeNaR. Of note, its Na+-pumping activity is significantly greater than that of the known Na+-pumping rhodopsin, KR2. We further characterized its photochemical properties as follows: (i) Visible spectroscopy and HPLC revealed that BeNaR has an absorption maximum at 524?nm with predominantly (>96%) the all-trans retinal conformer. (ii) Time-dependent thermal denaturation experiments revealed that BeNaR showed high thermal stability. (iii) The time-resolved flash-photolysis in the nanosecond to millisecond time domains revealed the presence of four kinetically distinctive photointermediates, K, L, M and O. (iv) Mutational analysis revealed that Asp101, which acts as a counterion, and Asp230 around the retinal were essential for the Na+-pumping activity. From the results, we propose a model for the outward Na+-pumping mechanism of BeNaR. The efficient Na+-pumping activity of BeNaR and its high stability make it a useful model both for ion transporters and optogenetics tools. en-copyright= kn-copyright= en-aut-name=KuriharaMarie en-aut-sei=Kurihara en-aut-mei=Marie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ThielVera en-aut-sei=Thiel en-aut-mei=Vera kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakahashiHirona en-aut-sei=Takahashi en-aut-mei=Hirona kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KojimaKeiichi en-aut-sei=Kojima en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WardDavid M. en-aut-sei=Ward en-aut-mei=David M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=BryantDonald A. en-aut-sei=Bryant en-aut-mei=Donald A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakaiMakoto en-aut-sei=Sakai en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 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 Biological Sciences, Tokyo Metropolitan University kn-affil= affil-num=3 en-affil=Department of Chemistry, Graduate School of Science, Okayama University of Science kn-affil= affil-num=4 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Land Resources and Environmental Sciences, Montana State University kn-affil= affil-num=6 en-affil=Department of Biochemistry and Molecular Biology, The Pennsylvania State University kn-affil= affil-num=7 en-affil=Department of Chemistry, Graduate School of Science, Okayama University of Science kn-affil= affil-num=8 en-affil=Atmosphere and Ocean Research Institute, The University of Tokyo kn-affil= affil-num=9 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=rhodopsin kn-keyword=rhodopsin en-keyword=ion transport kn-keyword=ion transport en-keyword=retinal kn-keyword=retinal en-keyword=isomerization kn-keyword=isomerization en-keyword=optogenetics kn-keyword=optogenetics END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=e1579 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Echelon analysis and its software for spatial lattice data en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, we explore the use of echelon analysis and its software named EcheScan for spatial lattice data. EcheScan is developed as a web application via an internet browser in R language and Shiny server for echelon analysis. The technique of echelon is proposed to analyze the topological structure for spatial lattice data. The echelon tree provides a dendrogram representation. Regional features, such as hierarchical spatial data structure and hotspots clusters, are shown in an echelon dendrogram. In addition, we introduce the conception of echelon with the values and neighbors for lattice data. We also explain the use of EcheScan for one- and two-dimensional regular lattice data. Furthermore, coronavirus disease 2019 death data corresponding to 50 US states are illustrated using EcheScan as an example of geospatial lattice data.

In this study, we conducted linkage analysis to localize the stb locus within a 1.6 Mb region on mouse chromosome 2 and identified a nonsense mutation in Adamtsl2 of stb/stb mice. Histological analysis revealed disturbed endochondral ossification with a reduced hypertrophic chondrocyte layer and stiff skin with a thickened dermal layer. These phenotypes are similar to those observed in humans and mice with ADAMTSL2/Adamtsl2 mutations. Moreover, stb/stb female mice exhibited severe uterine hypoplasia at 5 weeks of age and irregular estrous cycles at 10 weeks of age. In normal mice, Adamtsl2 was more highly expressed in the ovary and pituitary gland than in the uterus, and this expression was decreased in stb/stb mice. These findings suggest that Adamtsl2 may function in these organs rather than in the uterus. Thus, we analyzed Gh expression in the pituitary gland and plasma estradiol and IGF1 levels, which are required for the development of the female reproductive tract. There was no significant difference in Gh expression and estradiol levels, whereas IGF1 levels in stb/stb mice were significantly reduced to 54?59% of those in?+/+?mice. We conclude that Adamtsl2 is required for the development of the uterus and regulation of the estrous cycle in female mice, and decreased IGF1 may be related to these abnormalities. en-copyright= kn-copyright= en-aut-name=IwanagaYuka en-aut-sei=Iwanaga en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujiKaori en-aut-sei=Tsuji en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishimuraAyaka en-aut-sei=Nishimura en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TateishiKouji en-aut-sei=Tateishi en-aut-mei=Kouji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KakiuchiMisa en-aut-sei=Kakiuchi en-aut-mei=Misa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=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= END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=4 article-no= start-page=254 end-page=261 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=2022 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of bovine uterine gland functions in 2D and 3D culture system en-subtitle= kn-subtitle= en-abstract= kn-abstract=In ruminants, uterine glands play key roles in the establishment of pregnancy by secreting various factors into the uterine lumen. Although a three-dimensional (3D) culture system has been used for investigating cellular functions in vitro, the detailed functions of uterine gland have not been fully elucidated. In this study, we examined the benefits of 3D culture system to examine the innate functions of bovine uterine glands. Isolated bovine uterine glands were cultured on Matrigel (2D) or in Matrigel (3D), respectively, and the mRNA levels of secreted proteins (SERPINA14, MEP1B, APOA1, ARSA, CTGF, and SPP1) were measured in isolated and cultured uterine glands. The protein expression of estrogen receptor β (ERβ) and progesterone receptor (PR) and the establishment of apico-basal polarity were examined. In isolated uterine glands, the mRNA levels of secreted proteins changed during the estrous cycle. Although uterine glands cultured in both 2D and 3D expressed ERβ and PR, progesterone did not affect SERPINA14 mRNA expression. The expression of APOA1 mRNA in 2D cultured uterine glands did not respond to estrogen and progesterone. Additionally, the mRNA levels of secreted proteins in the 3D culture system were significantly higher than those in the 2D culture system, which might be attributed to the different cellular morphology between them. The locations of ZO-1 and β-catenin in 2D cultured uterine glands were disordered compared with 3D cultured uterine glands. These results showed that the hormonal responsiveness of secreted factor expression and cellular morphology were different between 2D and 3D cultured bovine uterine glands. en-copyright= kn-copyright= en-aut-name=SUGINOYosuke en-aut-sei=SUGINO en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SATOTaiki en-aut-sei=SATO en-aut-mei=Taiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YAMAMOTOYuki en-aut-sei=YAMAMOTO en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KIMURAKoji en-aut-sei=KIMURA en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Reproductive Physiology, Faculty of Agriculture, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Bovine kn-keyword=Bovine en-keyword=Secreted proteins kn-keyword=Secreted proteins en-keyword=Three-dimensional culture kn-keyword=Three-dimensional culture en-keyword=Uterine glands kn-keyword=Uterine glands END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=4 article-no= start-page=395 end-page=405 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association of Tumor Necrosis Factor-Alpha with Psychopathology in Patients with Schizophrenia en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated the relationship between serum tumor necrosis factor-alpha (TNF-α) levels and psychopathological symptoms, clinical and socio-demographic characteristics and antipsychotic therapy in individuals with schizophrenia. TNF-α levels were measured in 90 patients with schizophrenia and 90 healthy controls matched by age, gender, smoking status, and body mass index. The Positive and Negative Syndrome Scale (PANSS) was used to assess the severity of psychopathology in patients. No significant differences in TNF-α levels were detected between the patients and controls (p=0.736). TNF-α levels were not correlated with total, positive, negative, general, or composite PANSS scores (all p>0.05). A significant negative correlation was observed between TNF-α levels and the PANSS cognitive factor (ρ=?0.222, p=0.035). A hierarchical regression analysis identified the cognitive factor as a significant predictor of the TNF-α level (beta=?0.258, t=?2.257, p=0.027). There were no significant differences in TNF-α levels among patients treated with different types of antipsychotics (p=0.596). TNF-α levels correlated positively with the age of onset (ρ=0.233, p=0.027) and negatively with illness duration (ρ=?0.247, p=0.019) and antipsychotic treatment duration (ρ=?0.256, p=0.015). These results indicate that TNF-α may be involved in cognitive impairment in schizophrenia, and would be a potential clinical-state marker in schizophrenia. en-copyright= kn-copyright= en-aut-name=PavlovicMarko en-aut-sei=Pavlovic en-aut-mei=Marko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BabicDragan en-aut-sei=Babic en-aut-mei=Dragan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=RastovicPejana en-aut-sei=Rastovic en-aut-mei=Pejana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ArapovicJurica en-aut-sei=Arapovic en-aut-mei=Jurica kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MartinacMarko en-aut-sei=Martinac en-aut-mei=Marko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=JakovacSanja en-aut-sei=Jakovac en-aut-mei=Sanja kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=BarbaricRomana en-aut-sei=Barbaric en-aut-mei=Romana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=University Hospital Center Mostar, University of Mostar kn-affil= affil-num=2 en-affil=University Hospital Center Mostar, University of Mostar kn-affil= affil-num=3 en-affil=University Hospital Center Mostar, University of Mostar kn-affil= affil-num=4 en-affil=University Hospital Center Mostar, University of Mostar kn-affil= affil-num=5 en-affil=Health Care Center Mostar, University of Mostar kn-affil= affil-num=6 en-affil=University Hospital Center Mostar, University of Mostar kn-affil= affil-num=7 en-affil=University Hospital Center Mostar, University of Mostar kn-affil= en-keyword=tumor necrosis factor-alpha kn-keyword=tumor necrosis factor-alpha en-keyword=schizophrenia kn-keyword=schizophrenia en-keyword=psychopathology kn-keyword=psychopathology en-keyword=immune system kn-keyword=immune system END start-ver=1.4 cd-journal=joma no-vol=63 cd-vols= no-issue=12 article-no= start-page=1826 end-page=1839 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220518 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Plant Hormonomics: A Key Tool for Deep Physiological Phenotyping to Improve Crop Productivity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Agriculture is particularly vulnerable to climate change. To cope with the risks posed by climate-related stressors to agricultural production, global population growth, and changes in food preferences, it is imperative to develop new climate-smart crop varieties with increased yield and environmental resilience. Molecular genetics and genomic analyses have revealed that allelic variations in genes involved in phytohormone-mediated growth regulation have greatly improved productivity in major crops. Plant science has remarkably advanced our understanding of the molecular basis of various phytohormone-mediated events in plant life. These findings provide essential information for improving the productivity of crops growing in changing climates. In this review, we highlight the recent advances in plant hormonomics (multiple phytohormone profiling) and discuss its application to crop improvement. We present plant hormonomics as a key tool for deep physiological phenotyping, focusing on representative plant growth regulators associated with the improvement of crop productivity. Specifically, we review advanced methodologies in plant hormonomics, highlighting mass spectrometry- and nanosensor-based plant hormone profiling techniques. We also discuss the applications of plant hormonomics in crop improvement through breeding and agricultural management practices. en-copyright= kn-copyright= en-aut-name=HirayamaTakashi en-aut-sei=Hirayama en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=RIKEN Center for Sustainable Resource Science kn-affil= en-keyword=Biosensor kn-keyword=Biosensor en-keyword=Biostimulant kn-keyword=Biostimulant en-keyword=Breeding kn-keyword=Breeding en-keyword=Mass spectrometry kn-keyword=Mass spectrometry en-keyword=Phytohormone kn-keyword=Phytohormone END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=3 article-no= start-page=1067 end-page=1083 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230723 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Analysis of genetic diversity and population structure in Cambodian melon landraces using molecular markers en-subtitle= kn-subtitle= en-abstract= kn-abstract=Genetic diversity of Cambodian melons was evaluated by the analysis of 12 random amplified polymorphic DNA (RAPD) and 7 simple sequence repeat (SSR) markers using 62 accessions of melon landraces and compared with 231 accessions from other areas for genetic characterization of Cambodian melons. Among 62 accessions, 56 accessions were morphologically classified as small-seed type with seed lengths shorter than 9 mm, as in the horticultural groups Conomon and Makuwa. Gene diversity of Cambodian melons was 0.228, which was equivalent to those of the groups Conomon and Makuwa and smaller than those of Vietnamese and Central Asian landraces. A phylogenetic tree constructed from a genetic distance matrix classified 293 accessions into three major clusters. Small-seed type accessions from East and Southeast Asia formed clusters I and II, which were distantly related with cluster III consisting of large-seed type melon from other areas. All Cambodian melons belonged to cluster I (except three accessions) along with those from Thailand, Myanmar, Yunnan (China), and Vietnam (“Dua thom” in the northwest), thus indicating genetic similarity in these areas. In addition, the Cambodian melons were not differentiated among geographical populations. Conomon and Makuwa were classified into cluster II, together with melon groups from the plains of Vietnam. The presence of two groups of melons in Southeast Asia was also indicated by population structure and principal coordinate analysis. These results indicated a close genetic relationship between Cambodia and the neighboring countries, thus suggesting that Cambodian melons are not directly related to the establishment of Conomon and Makuwa. en-copyright= kn-copyright= en-aut-name=NazninPervin Mst en-aut-sei=Naznin en-aut-mei=Pervin Mst kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ImohOdirichi Nnennaya en-aut-sei=Imoh en-aut-mei=Odirichi Nnennaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaKatsunori en-aut-sei=Tanaka en-aut-mei=Katsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SreynechOuch en-aut-sei=Sreynech en-aut-mei=Ouch kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShigitaGentaro en-aut-sei=Shigita en-aut-mei=Gentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SopheaYon en-aut-sei=Sophea en-aut-mei=Yon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SophanySakhan en-aut-sei=Sophany en-aut-mei=Sakhan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MakaraOuk en-aut-sei=Makara en-aut-mei=Ouk kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TomookaNorihiko en-aut-sei=Tomooka en-aut-mei=Norihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MondenYuki en-aut-sei=Monden en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NishidaHidetaka en-aut-sei=Nishida en-aut-mei=Hidetaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KatoKenji en-aut-sei=Kato en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Agriculture and Life Science, Hirosaki University kn-affil= affil-num=4 en-affil=Cambodian Agricultural Research and Development Institute kn-affil= affil-num=5 en-affil=Department of Life Science Systems, Technical University of Munich kn-affil= affil-num=6 en-affil=Cambodian Agricultural Research and Development Institute kn-affil= affil-num=7 en-affil=Cambodian Agricultural Research and Development Institute kn-affil= affil-num=8 en-affil=Plant Breeder, Retired Director of the Cambodian Agricultural Research and Development Institute kn-affil= affil-num=9 en-affil=Research Center of Genetic Resources, National Agriculture and Food Research Organization (NARO) kn-affil= affil-num=10 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=12 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Cambodia kn-keyword=Cambodia en-keyword=Conomon kn-keyword=Conomon en-keyword=Cucumis melo kn-keyword=Cucumis melo en-keyword=Genetic diversity kn-keyword=Genetic diversity en-keyword=Landraces kn-keyword=Landraces en-keyword=RAPD kn-keyword=RAPD en-keyword=SSR kn-keyword=SSR END start-ver=1.4 cd-journal=joma no-vol=40 cd-vols= no-issue=7 article-no= start-page=msad151 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230707 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Ongoing Rapid Evolution of a Post-Y Region Revealed by Chromosome-Scale Genome Assembly of a Hexaploid Monoecious Persimmon (Diospyros kaki) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Plants have evolved sex chromosomes independently in many lineages, and loss of separate sexes can also occur. In this study, we assembled a monoecious recently hexaploidized persimmon (Diospyros kaki), in which the Y chromosome has lost the maleness-determining function. Comparative genomic analysis of D. kaki and its dioecious relatives uncovered the evolutionary process by which the nonfunctional Y chromosome (or Y-monoecy) was derived, which involved silencing of the sex-determining gene, OGI, approximately 2 million years ago. Analyses of the entire X and Y-monoecy chromosomes suggested that D. kaki's nonfunctional male-specific region of the Y chromosome (MSY), which we call a post-MSY, has conserved some characteristics of the original functional MSY. Specifically, comparing the functional MSY in Diospyros lotus and the nonfunctional "post-MSY" in D. kaki indicated that both have been rapidly rearranged, mainly via ongoing transposable element bursts, resembling structural changes often detected in Y-linked regions, some of which can enlarge the nonrecombining regions. The recent evolution of the post-MSY (and possibly also MSYs in dioecious Diospyros species) therefore probably reflects these regions' ancestral location in a pericentromeric region, rather than the presence of male-determining genes and/or genes controlling sexually dimorphic traits. en-copyright= kn-copyright= en-aut-name=HoriuchiAyano en-aut-sei=Horiuchi en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MasudaKanae en-aut-sei=Masuda en-aut-mei=Kanae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShirasawaKenta en-aut-sei=Shirasawa en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OnoueNoriyuki en-aut-sei=Onoue en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujitaNaoko en-aut-sei=Fujita en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=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=AkagiTakashi en-aut-sei=Akagi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Frontier Research and Development, Kazusa DNA Research Institute kn-affil= affil-num=4 en-affil=Institute of Fruit Tree and Tea Science, NARO kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=sex chromosome kn-keyword=sex chromosome en-keyword=genome assembly kn-keyword=genome assembly en-keyword=monoecy kn-keyword=monoecy en-keyword=transposable elements kn-keyword=transposable elements END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=8386 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230524 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comprehensive hemocompatibility analysis on the application of diamond-like carbon to ePTFE artificial vascular prosthesis en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study was to obtain comprehensive data regarding the hemocompatibility of diamond-like carbon (DLC)-coated expanded polytetrafluoroethylene (ePTFE). DLC increased the hydrophilicity and smoothened the surface and fibrillar structure, respectively, of the ePTFE. DLC-coated ePTFE had more albumin and fibrinogen adsorption and less platelet adhesion than uncoated ePTFE. There were scarce red cell attachments in in vitro human and in vivo animal (rat and swine) whole blood contact tests in both DLC-coated and uncoated ePTFE. DLC-coated ePTFE had a similar but marginally thicker band movement than uncoated-ePTFE with SDS-PAGE after human whole blood contact test. In addition, survival studies of aortic graft replacement in rats (1.5 mm graft) and arteriovenous shunt in goats (4 mm graft) were performed to compare the patency and clot formation between DLC-coated and uncoated ePTFE grafts. Comparable patency was observed in both animal models. However, clots were observed in the luminal surface of the patent 1.5 mm DLC-coated ePTFE grafts, but not in that of uncoated ePTFE grafts. In conclusions, hemocompatibility of DLC-coated ePTFE was high and comparable to that of uncoated ePTFE. However, it failed to improve the hemocompatibility of 1.5 mm ePTFE graft probably because increased fibrinogen adsorption canceled the other beneficial effects of DLC. en-copyright= kn-copyright= en-aut-name=GoyamaTakashi en-aut-sei=Goyama en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiiYasuhiro en-aut-sei=Fujii en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MuraokaGenya en-aut-sei=Muraoka en-aut-mei=Genya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakataniTatsuyuki en-aut-sei=Nakatani en-aut-mei=Tatsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=ImaiYuichi en-aut-sei=Imai en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KuwadaNoriaki en-aut-sei=Kuwada en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsujiTatsunori en-aut-sei=Tsuji en-aut-mei=Tatsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShukuTakayuki en-aut-sei=Shuku en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=UchidaHaruhito A. en-aut-sei=Uchida en-aut-mei=Haruhito A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 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=12 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=13 ORCID= affil-num=1 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Institute of Frontier Science and Technology, Okayama University of Science kn-affil= affil-num=5 en-affil=Department of Pharmacology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Institute of Frontier Science and Technology, Okayama University of Science kn-affil= affil-num=7 en-affil=Department of Cardiovascular Surgery, Kawasaki Medical Hospital kn-affil= affil-num=8 en-affil=Department of Cardiovascular Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Civil Engineering, Okayama University Graduate School of Environmental and Life Science kn-affil= affil-num=10 en-affil=Department of Chronic Kidney Disease and Cardiovascular Disease, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Translational Research and Drug Development, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Division of Medical Safety Management, Safety Management Facility, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Cardiovascular Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=6 article-no= start-page=312 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230529 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Edge Device Framework in SEMAR IoT Application Server Platform en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, the Internet of Things (IoT) has become widely used at various places and for various applications. To facilitate this trend, we have developed the IoT application server platform called SEMAR (Smart Environmental Monitoring and Analytical in Real-Time), which offers standard features for collecting, displaying, and analyzing sensor data. An edge device is usually installed to connect sensors with the server, where the interface configuration, the data processing, the communication protocol, and the transmission interval need to be defined by the user. In this paper, we proposed an edge device framework for SEMAR to remotely optimize the edge device utilization with three phases. In the initialization phase, it automatically downloads the configuration file to the device through HTTP communications. In the service phase, it converts data from various sensors into the standard data format and sends it to the server periodically. In the update phase, it remotely updates the configuration through MQTT communications. For evaluations, we applied the proposal to the fingerprint-based indoor localization system (FILS15.4) and the data logging system. The results confirm the effectiveness in utilizing SEMAR to develop IoT application systems. 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=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=ItoSho en-aut-sei=Ito en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=KuribayashiMinoru en-aut-sei=Kuribayashi en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=ShimazuJunya en-aut-sei=Shimazu en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=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= affil-num=6 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Department of Informatic and Computer, Politeknik Elektronika Negeri Surabaya kn-affil= en-keyword=Internet of Things kn-keyword=Internet of Things en-keyword=edge device kn-keyword=edge device en-keyword=framework kn-keyword=framework en-keyword=application server platform kn-keyword=application server platform en-keyword=SEMAR kn-keyword=SEMAR END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=1730 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structure and mechanism of oxalate transporter OxlT in an oxalate-degrading bacterium in the gut microbiota en-subtitle= kn-subtitle= en-abstract= kn-abstract=An oxalate-degrading bacterium in the gut microbiota absorbs food-derived oxalate to use this as a carbon and energy source, thereby reducing the risk of kidney stone formation in host animals. The bacterial oxalate transporter OxlT selectively uptakes oxalate from the gut to bacterial cells with a strict discrimination from other nutrient carboxylates. Here, we present crystal structures of oxalate-bound and ligand-free OxlT in two distinct conformations, occluded and outward-facing states. The ligand-binding pocket contains basic residues that form salt bridges with oxalate while preventing the conformational switch to the occluded state without an acidic substrate. The occluded pocket can accommodate oxalate but not larger dicarboxylates, such as metabolic intermediates. The permeation pathways from the pocket are completely blocked by extensive interdomain interactions, which can be opened solely by a flip of a single side chain neighbouring the substrate. This study shows the structural basis underlying metabolic interactions enabling favourable symbiosis. en-copyright= kn-copyright= en-aut-name=Jaunet-LaharyTitouan en-aut-sei=Jaunet-Lahary en-aut-mei=Titouan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimamuraTatsuro en-aut-sei=Shimamura en-aut-mei=Tatsuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HayashiMasahiro en-aut-sei=Hayashi en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NomuraNorimichi en-aut-sei=Nomura en-aut-mei=Norimichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HirasawaKouta en-aut-sei=Hirasawa en-aut-mei=Kouta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShimizuTetsuya en-aut-sei=Shimizu en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamashitaMasao en-aut-sei=Yamashita en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsutsumiNaotaka en-aut-sei=Tsutsumi en-aut-mei=Naotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SuehiroYuta en-aut-sei=Suehiro en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=11 ORCID= en-aut-name=TamuraTakashi en-aut-sei=Tamura en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=IwanariHiroko en-aut-sei=Iwanari en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=HamakuboTakao en-aut-sei=Hamakubo en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=IwataSo en-aut-sei=Iwata en-aut-mei=So kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=OkazakiKei-Ichi en-aut-sei=Okazaki en-aut-mei=Kei-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=HiraiTeruhisa en-aut-sei=Hirai en-aut-mei=Teruhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=YamashitaAtsuko en-aut-sei=Yamashita en-aut-mei=Atsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= affil-num=1 en-affil=Research Center for Computational Science, Institute for Molecular Science, National Institutes of Natural Sciences kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Kyoto University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Kyoto University kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Kyoto University kn-affil= affil-num=6 en-affil=RIKEN SPring-8 Center kn-affil= affil-num=7 en-affil=RIKEN SPring-8 Center kn-affil= affil-num=8 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=School of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Graduate School of Environmental and Life Sciences, Okayama University kn-affil= affil-num=13 en-affil=Research Center for Advanced Science and Technology, The University of Tokyo kn-affil= affil-num=14 en-affil=Research Center for Advanced Science and Technology, The University of Tokyo kn-affil= affil-num=15 en-affil=Graduate School of Medicine, Kyoto University kn-affil= affil-num=16 en-affil=Research Center for Computational Science, Institute for Molecular Science, National Institutes of Natural Sciences kn-affil= affil-num=17 en-affil=RIKEN SPring-8 Center kn-affil= affil-num=18 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=20628 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221130 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Early-stage antibody kinetics after the third dose of BNT162b2 mRNA COVID-19 vaccination measured by a point-of-care fingertip whole blood testing en-subtitle= kn-subtitle= en-abstract= kn-abstract=Amid the Coronavirus Disease 2019 pandemic, we aimed to demonstrate the accuracy of the fingertip whole blood sampling test (FWT) in measuring the antibody titer and uncovering its dynamics shortly after booster vaccination. Mokobio SARS-CoV-2 IgM & IgG Quantum Dot immunoassay (Mokobio Biotechnology R&D Center Inc., MD, USA) was used as a point-of-care FWT in 226 health care workers (HCWs) who had received two doses of the BNT162b2 mRNA vaccine (Pfizer-BioNTech) at least 8 months prior. Each participant tested their antibody titers before and after the third-dose booster up to 14-days. The effect of the booster was observed as early as the fourth day after vaccination, which exceeded the detection limit (>30,000 U/mL) by 2.3% on the fifth day, 12.2% on the sixth day, and 22.5% after the seventh day. Significant positive correlations were observed between the pre- and post-vaccination (the seventh and eighth days) antibody titers (correlation coefficient, 0.405; p<0.001). FWT is useful for examining antibody titers as a point-of-care test. Rapid response of antibody titer started as early as the fourth day post-vaccination, while the presence of weak responders to BNT162b2 vaccine was indicated. en-copyright= kn-copyright=

en-abstract= kn-abstract=To uncover population structure, phylogenetic relationship, and diversity in melons along the famous Silk Road, a seed size measurement and a phylogenetic analysis using five chloroplast genome markers, 17 RAPD markers and 11 SSR markers were conducted for 87 Kazakh melon accessions with reference accessions. Kazakh melon accessions had large seed with exception of two accessions of weedy melon, Group Agrestis, and consisted of three cytoplasm types, of which Ib-1/-2 and Ib-3 were dominant in Kazakhstan and nearby areas such as northwestern China, Central Asia and Russia. Molecular phylogeny showed that two unique genetic groups, STIa-2 with Ib-1/-2 cytoplasm and STIa-1 with Ib-3 cytoplasm, and one admixed group, STIAD combined with STIa and STIb, were prevalent across all Kazakh melon groups. STIAD melons that phylogenetically overlapped with STIa-1 and STIa-2 melons were frequent in the eastern Silk Road region, including Kazakhstan. Evidently, a small population contributed to melon development and variation in the eastern Silk Road. Conscious preservation of fruit traits specific to Kazakh melon groups is thought to play a role in the conservation of Kazakh melon genetic variation during melon production, where hybrid progenies were generated through open pollination. en-copyright= kn-copyright= en-aut-name=TanakaKatsunori en-aut-sei=Tanaka en-aut-mei=Katsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugiyamaMitsuhiro en-aut-sei=Sugiyama en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShigitaGentaro en-aut-sei=Shigita en-aut-mei=Gentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MurakamiRyoma en-aut-sei=Murakami en-aut-mei=Ryoma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DuongThanh-Thuy en-aut-sei=Duong en-aut-mei=Thanh-Thuy kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AierkenYasheng en-aut-sei=Aierken en-aut-mei=Yasheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ArtemyevaAnna M en-aut-sei=Artemyeva en-aut-mei=Anna M kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MamypbelovZharas en-aut-sei=Mamypbelov en-aut-mei=Zharas kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IshikawaRyuji en-aut-sei=Ishikawa en-aut-mei=Ryuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NishidaHidetaka en-aut-sei=Nishida en-aut-mei=Hidetaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KatoKenji en-aut-sei=Kato en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Faculty of Agriculture and Life Science, Hirosaki University kn-affil= affil-num=2 en-affil=Institute of Vegetable and Floriculture Science, National Agriculture and Food Research Organization (NARO) kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Agriculture and Life Science, Hirosaki University kn-affil= affil-num=5 en-affil=Faculty of Agronomy, University of Agriculture and Forestry, Hue University kn-affil= affil-num=6 en-affil=Center for Hami Melon, Xinjiang Academy of Agricultural Sciences kn-affil= affil-num=7 en-affil=All-Russian Institute of Plant Genetic Resources on the name of N.I.Vavilov (VIR) kn-affil= affil-num=8 en-affil=Kazakhstan Research Institute of Potato and Vegetable Growing LLC kn-affil= affil-num=9 en-affil=Faculty of Agriculture and Life Science, Hirosaki University kn-affil= affil-num=10 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Central Asia kn-keyword=Central Asia en-keyword=Cucumis melo kn-keyword=Cucumis melo en-keyword=diversity kn-keyword=diversity en-keyword=genetic resources kn-keyword=genetic resources en-keyword=on-farm conservation kn-keyword=on-farm conservation END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=2 article-no= start-page=826 end-page=834 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Flotation kinetics of aluminum powders derived from waste crystalline silicon solar cells and its comparison between batch, continuous and column flotation practices en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, floatability rate of aluminum (Al) powders was analyzed for the purpose of separating valuable resources from residual materials in waste photovoltaic (PV) solar cells, and equations for flotation recovery were developed for various flotation types according to the rate-determining steps of the gas flowrate and feed rate. The flotation rate became a zero-order reaction at the rate-determining step of the gas flow rate and had the same form between a batch and continuous typed practices by substituting residence time with real time. Under the rate-determining step of the feed rate, the flotation rate was expressed by the linear combination of the first-order reaction of an even group material. The flotation recovery rate of Al powders was analyzed by the data of a batch floatability experiment and indicated by the linear expression of the first-order reaction of two groups due to the rate-determining step of the feed rate. The calculated separation recovery of n-cell type device increased as the number of cells increased and approached that of the batch and column types. en-copyright= kn-copyright= en-aut-name=KatoYoshiei en-aut-sei=Kato en-aut-mei=Yoshiei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HaradaSho en-aut-sei=Harada en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishimuraNoriko en-aut-sei=Nishimura en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UddinMd.

In Vietnam, around 70,000 households were displaced in 2020, causing uncertainty and social disruption. The aim of this study is to analyze the effects of resettlement on the livelihood and food security of displaced households, explore the underlying challenges and causes of these effects, and recommend policy implications for sustainable livelihood development and poverty alleviation. This study conducted a decade-long sociological examination of three displaced communities in Thua Thien Hue province, Vietnam. Our research reveals that resettled households are unable to regain their former standard of living due to the loss of cultivated land and restricted access to public property, which exacerbates food insecurity. Unemployment, illiteracy, and low income further perpetuate poverty. These findings highlight the deficiencies in current policies and planning approaches and call for implementing socially responsible resettlement processes guided by principles of equity. Addressing the inequalities arising from displacement and enabling affected communities to participate in growth is economically justified and morally imperative. en-copyright= kn-copyright= en-aut-name=TyPham Huu en-aut-sei=Ty en-aut-mei=Pham Huu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LauraBaas en-aut-sei=Laura en-aut-mei=Baas kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=PhuongTran Thi en-aut-sei=Phuong en-aut-mei=Tran Thi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanNguyen Quang en-aut-sei=Tan en-aut-mei=Nguyen Quang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Faculty of Land Resources and Agricultural Environment, University of Agriculture and Forestry, Hue University kn-affil= affil-num=2 en-affil=MAEX Platform, Mayor of Karnebeeklaan kn-affil= affil-num=3 en-affil=Faculty of Land Resources and Agricultural Environment, University of Agriculture and Forestry, Hue University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=food insecurity kn-keyword=food insecurity en-keyword=hydropower dams kn-keyword=hydropower dams en-keyword=impoverishment kn-keyword=impoverishment en-keyword=poverty kn-keyword=poverty en-keyword=livelihoods kn-keyword=livelihoods END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=4 article-no= start-page=e1010732 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230428 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Overexpression profiling reveals cellular requirements in the context of genetic backgrounds and environments en-subtitle= kn-subtitle= en-abstract= kn-abstract=Overexpression can help life adapt to stressful environments, making an examination of overexpressed genes valuable for understanding stress tolerance mechanisms. However, a systematic study of genes whose overexpression is functionally adaptive (GOFAs) under stress has yet to be conducted. We developed a new overexpression profiling method and systematically identified GOFAs in Saccharomyces cerevisiae under stress (heat, salt, and oxidative). Our results show that adaptive overexpression compensates for deficiencies and increases fitness under stress, like calcium under salt stress. We also investigated the impact of different genetic backgrounds on GOFAs, which varied among three S. cerevisiae strains reflecting differing calcium and potassium requirements for salt stress tolerance. Our study of a knockout collection also suggested that calcium prevents mitochondrial outbursts under salt stress. Mitochondria-enhancing GOFAs were only adaptive when adequate calcium was available and non-adaptive when calcium was deficient, supporting this idea. Our findings indicate that adaptive overexpression meets the cell's needs for maximizing the organism's adaptive capacity in the given environment and genetic context. Author summaryThe study aimed to investigate how overexpression of genes can aid organisms in adapting to stress. The researchers utilized a new method to identify genes in yeast that demonstrated functional adaptability when overexpressed under stress such as heat, salt, and oxidative stress. The results indicated that overexpressing specific genes, like calcium, during salt stress could counteract deficiencies and improve the organism's ability to withstand stress. The study also examined the effect of different genetic backgrounds on these genes and discovered that the impact differed among various yeast strains. Additionally, the study revealed that calcium could play a key role in adapting to salt stress by preventing mitochondrial outbursts. These findings suggest that overexpressing certain genes can help the organism maximize its adaptability to stress in a given environment and genetic context. en-copyright= kn-copyright= en-aut-name=SaekiNozomu en-aut-sei=Saeki en-aut-mei=Nozomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoChie en-aut-sei=Yamamoto en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EguchiYuichi en-aut-sei=Eguchi en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SekitoTakayuki en-aut-sei=Sekito en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShigenobuShuji en-aut-sei=Shigenobu en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshimuraMami en-aut-sei=Yoshimura en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YashirodaYoko en-aut-sei=Yashiroda en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=BooneCharles en-aut-sei=Boone en-aut-mei=Charles kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoriyaHisao en-aut-sei=Moriya en-aut-mei=Hisao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Biomedical Business Center, RICOH Futures BU kn-affil= affil-num=4 en-affil=Graduate School of Agriculture, Ehime University kn-affil= affil-num=5 en-affil=National Institute for Basic Biology kn-affil= affil-num=6 en-affil=RIKEN Center for Sustainable Resource Science kn-affil= affil-num=7 en-affil=RIKEN Center for Sustainable Resource Science kn-affil= affil-num=8 en-affil=RIKEN Center for Sustainable Resource Science kn-affil= affil-num=9 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=2 article-no= start-page=185 end-page=192 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202304 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluating the Coping Behavior of Children with Psychosomatic Disorders under Frustrating Situations Simulated Using the Rosenzweig Picture-Frustration Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Psychosomatic disorders are influenced by psychosocial factors such as interpersonal relationships. Coping behaviors, especially in frustrating situations, reflect a patient’s ability to cope with stress, and it is important to assess these behaviors for the treatment of psychosomatic diseases. This study aimed to clarify the interpersonal relationships and coping behaviors of pediatric patients with psychosomatic diseases during frustrating situations simulated using the Rosenzweig Picture-Frustration study. This retrospective study included 126 patients (41 male, 85 female) with an average age of 12.9 (6-16) years who were consulted at the Department of Pediatric Psychosomatic Medicine at Okayama University Hospital from 2013 to 2018 and underwent the P-F study. Each score was compared with a standardization sample. The mean group conformity rating did not differ significantly between the participants and healthy children. Compared with healthy children, those with psychosomatic diseases were less likely to explain their perspective. The children with psychosomatic disorders responded to frustrating situations in a sensible and age-appropriate manner. However, they were less likely to respond by explaining their perspective to protect themselves. en-copyright= kn-copyright= en-aut-name=SugiharaAkiko en-aut-sei=Sugihara en-aut-mei=Akiko kn-aut-name=

combined hydrologic - rice growth model en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effects of climate change on agriculture are a major concern for global food security. In this study, the impacts of climate change on rainfed rice production in the granary of Cambodia were examined on a basin scale by developing and applying a combined model consisting of a crop model and a basin-scale distributed hydrological model. The response of rice production to soil-water availability was simulated for past (1981?2000) and future (2041?2060, 2081?2100) periods. From 34 general circulation models (GCMs) that participated in the Coupled Model Intercomparison Project Phase 5 (CMIP5), 5 GCMs were selected by evaluating monthly rainfall in the past. Although annual rainfall was projected to increase by all five selected GCMs, notable decreases in rainfed rice production were projected with 3 GCMs, while small changes were projected with the other 2 GCMs. The main factor restricting future rice production was soil water availability, brought by the projected change in the seasonal distribution of rainfall and the projected more severe dry spells in the early monsoon season. The results suggest the importance of the selection and bias correction of GCMs to force rice crop models and of the simulation of soil water flow on a basin scale for the assessment of rain-fed rice production. In particular, improvements in projections of rainfall amounts over shorter periods rather than annual or seasonal periods, which fit within the time scales of rice plant growth, were suggested to be important. en-copyright= kn-copyright= en-aut-name=TsujimotoK. en-aut-sei=Tsujimoto en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuriyaN. en-aut-sei=Kuriya en-aut-mei=N. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhtaT. en-aut-sei=Ohta en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HommaK. en-aut-sei=Homma en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ImM.So en-aut-sei=Im en-aut-mei=M.So 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=Faculty of Environmental Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Assistance Unit for Research and Engineering Development (U-PRIMO) kn-affil= affil-num=4 en-affil=Graduate School of Agricultural Science, Tohoku University kn-affil= affil-num=5 en-affil=Ministry of Water Resources and Meteorology (MOWRAM) of Cambodia kn-affil= en-keyword=Climate change impact assessment kn-keyword=Climate change impact assessment en-keyword=Soil moisture kn-keyword=Soil moisture en-keyword=Crop model kn-keyword=Crop model en-keyword=Rice production kn-keyword=Rice production en-keyword=Rainfed paddy kn-keyword=Rainfed paddy en-keyword=GCM kn-keyword=GCM END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=1 article-no= start-page=39 end-page=42 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Examining the association between vaccine reactogenicity and antibody titer dynamics after the third dose of BNT162b2 vaccine using a mixed-effects model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: To mitigate the COVID-19 pandemic, many countries have recommended the use of booster vac-cinations. The relationship between the degree of adverse vaccine reactions and elevated antibody titers is of interest; however, no studies have investigated the temporal changes in antibody titers based on repeated measurements after a third dose of the BNT162b2 vaccine.
Methods: This prospective longitudinal cohort study was conducted with 62 healthcare workers who received a third dose of the BNT162b2 at Okayama University Hospital, Japan. Venous blood draw and fingertip whole blood test sample collection were conducted at the early (3-13 days) and 1-month time points; only FWT sample collection was conducted at the 2-month time point. Information on adverse reactions within 1 week after vaccination was also obtained. The association between fever of 37.5 degrees C or higher and antibody titers after the third dose of BNT162b2 was examined using a mixed-effects model and Poisson regression with robust variance.
Results: A trend toward higher antibody titers in the early period after vaccination was observed in the febrile individuals, but the differences were not significant at 1 and 2 months post-vaccination (the partial regression coefficient for fever was 8094.3 [-1910.2, 18,098.8] at 1 month after vaccination, and 1764.1 [-4133.9, 7662.1] at 2 months after vaccination in the adjusted models).
Conclusion: The findings suggest that the presence of fever after the third vaccine does not predict a sustained elevation in serum antibody titers. 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=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=NakayamaMasanori en-aut-sei=Nakayama en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FurukawaMasanori en-aut-sei=Furukawa en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Office of Innovative Medicine, Organization for Research Strategy and Development, Okayama University kn-affil= affil-num=4 en-affil=Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=5 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=SARS-CoV-2 kn-keyword=SARS-CoV-2 en-keyword=Vaccine kn-keyword=Vaccine en-keyword=Antibody kn-keyword=Antibody en-keyword=Reactogenicity kn-keyword=Reactogenicity en-keyword=Adverse reaction kn-keyword=Adverse reaction en-keyword=Mixed-effects model kn-keyword=Mixed-effects model END start-ver=1.4 cd-journal=joma no-vol=44 cd-vols= no-issue= article-no= start-page=108524 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The dataset of Japanese patents and patents' holding firms in green vehicle powertrains field en-subtitle= kn-subtitle= en-abstract= kn-abstract=In 2020, the Government of Japan declared "2050 carbon neutral" and launched a long-term strategy to create a "virtuous cycle of economy and environment".(1) Japanese firms possess many technologies that contribute to decarbonization, which is important to expand investment for Green Technology (environmental technology) development. As automobiles are major contributors to greenhouse gas emissions [1], the technological shift towards vehicle powertrain systems is an attempt to lower problems like emissions of carbon dioxide, nitrogen oxides [2]. On the other hand, patent data are the most reliable business performance for applied research and development activities when investigating the knowledge domains or the technology evolution (Wand, 1997). Our paper describes a Japanese patents dataset of the vehicle powertrain systems for hybrid electric vehicle (HEV), battery electric vehicle (BEV) and fuel cell electric vehicles (FCEV). In this paper we create a method of bombinating international patent classification (IPC) and keywords to define "green" patents in vehicle powertrains field, using patent data which were applied to Japan Patent Office recorded on EPO's PATSTAT database during 2010 similar to 2019 year. When analyze patents, it is necessary to consider the social situation of each country including language background, we collect patents description documents (abstracts and titles) not only written in English but also in Japanese. Finally, we build a database includes 6025 green patents' description documents and 266 patents' holding firms. With which we then identify 3756 HEV patents, 1716 BEV patents, and 553 FCEV patents. Data about patent holding firms is also appended. The full dataset may be useful to researchers who would like to do further search like natural language processing and machine learning on patent description documents, statistical data analysis for empirical economics. en-copyright= kn-copyright= en-aut-name=JiangJiaming en-aut-sei=Jiang en-aut-mei=Jiaming kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BabaKensuke en-aut-sei=Baba en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ZhaoYu en-aut-sei=Zhao en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FengJunshi en-aut-sei=Feng en-aut-mei=Junshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KumagaiSou en-aut-sei=Kumagai en-aut-mei=Sou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Humanities and Social Science, Okayama University kn-affil= affil-num=2 en-affil=Cyber-Physical Engineering Informatics Research Core, Okayama University kn-affil= affil-num=3 en-affil=School of Management, Department of Management, Tokyo University of Science kn-affil= affil-num=4 en-affil=Graduate School of Humanities and Social Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Electrical and Communication Engineering, Faculty of Engineering, Okayama University kn-affil= en-keyword=Patents kn-keyword=Patents en-keyword=Green innovation kn-keyword=Green innovation en-keyword=Vehicle powertrain kn-keyword=Vehicle powertrain en-keyword=Hybrid electric vehicle kn-keyword=Hybrid electric vehicle en-keyword=Battery electric vehicle kn-keyword=Battery electric vehicle en-keyword=Fuel cell electric vehicles kn-keyword=Fuel cell electric vehicles END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220922 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=航空レーザー測深を用いた水環境特性のリモートセンシング技術の開発と河川実務のための水理モデリングへの応用 kn-title=Development of remote sensing of hydro-environmental attributes using airborne topo-bathymetric LiDAR and their application to hydraulic modeling for river management tasks en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MD.

The two measurement planes were parallel to the orbitomeatal plane: namely, a plane passing through the dorsum sellae (DS) and the plane superior to that with the maximal area (Max plane). A protractor was used to circumferentially measure the lengths from the central point to the outer surface of the skull. A total of 487 images were extracted. The distances between the DS and Max planes were consistently almost 30 mm for each age group, so we fixed the Max plane as the plane 30 mm superior to the DS plane. Finally, we established datasets of normal values for each age group and sex. Using these norms, perioperative evaluation of various cranial deformities could be performed more easily and circumstantially. en-copyright= kn-copyright= en-aut-name=KomagoeSho en-aut-sei=Komagoe en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SenooTakaya en-aut-sei=Senoo en-aut-mei=Takaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShiraishiYoshinori en-aut-sei=Shiraishi en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsumotoHiroshi en-aut-sei=Matsumoto en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KimataYoshihiro en-aut-sei=Kimata en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=craniofacial surgery kn-keyword=craniofacial surgery en-keyword=craniosynostoses kn-keyword=craniosynostoses en-keyword=horizontal plane kn-keyword=horizontal plane en-keyword=Japanese children kn-keyword=Japanese children en-keyword=reference values kn-keyword=reference values END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue= article-no= start-page=977049 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Does ESG investment reduce carbon emissions in China? en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study explores the relationship between ESG investments and carbon emissions in China.

The impact of ESG investment is heterogeneous across the developed and underdeveloped regions. Environmental investments in the advanced eastern region have significantly improved carbon productivity. In contrast, environmental investments in the central and western regions significantly reduced carbon emissions, but they have little impact on carbon productivity. en-copyright= kn-copyright= en-aut-name=CongYingnan en-aut-sei=Cong en-aut-mei=Yingnan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZhuChen en-aut-sei=Zhu en-aut-mei=Chen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HouYufei en-aut-sei=Hou en-aut-mei=Yufei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TianShuairu en-aut-sei=Tian en-aut-mei=Shuairu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=CaiXiaojing en-aut-sei=Cai en-aut-mei=Xiaojing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Business School, China University of Political Science and Law kn-affil= affil-num=2 en-affil=Business School, China University of Political Science and Law kn-affil= affil-num=3 en-affil=Business School, China University of Political Science and Law kn-affil= affil-num=4 en-affil=Research Center of Finance, Shanghai Business School kn-affil= affil-num=5 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil= en-keyword=ESG investment kn-keyword=ESG investment en-keyword=carbon emission kn-keyword=carbon emission en-keyword=carbon productivity kn-keyword=carbon productivity en-keyword=regional effect kn-keyword=regional effect en-keyword=green transition kn-keyword=green transition END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=63 end-page=77 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021326 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Energizing Communities Through Partnerships With E en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aims to specify the contextual conditions that allow for the success of community renewable energy projects, against the background of the expanding use of renewable energy. It analyzes cases where farmers invested in organizations to establish ownership of hydropower plants in the Chugoku region, Japan. Community renewable energy projects derived from local initiatives to provide an alternative energy resource and serve as a catalyst for rural development. However,?the costs?of small hydropower plant construction and the expert knowledge required for their operation could hinder the diffusion of the technology. Population decline and aging in rural communities also constrain the development of community renewable energy projects. This study presents cases that illuminate the conditions?enabling these organizations to succeed in securing the necessary resources for the operation of their renewable energy plants.?The survey illustrates how studied organizations have opted to collaborate with external actors to construct or refurbish their plants. The findings indicate that as building partnerships with external actors often becomes essential, it is vital to develop a business-minded framework in which both communities and external actors can financially benefit from introducing small hydropower projects. The cases also reveal that in building collaborative relationships, broad disparities exist between communities and external actors in financial power and expert knowledge, which give the latter substantial advantages in negotiations. An additional important claim derived is that, for an effective partnership that enables a successful community renewable energy project, a third party with expert knowledge and the ability to?audit partnership-building processes could play a crucial role in securing community initiatives and independence. en-copyright= kn-copyright= en-aut-name=HondaYasuko en-aut-sei=Honda en-aut-mei=Yasuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword= Community renewable energy kn-keyword= Community renewable energy en-keyword=rural community kn-keyword=rural community en-keyword=local initiative kn-keyword=local initiative en-keyword= Japan Agricultural Cooperatives kn-keyword= Japan Agricultural Cooperatives en-keyword=energy cooperative kn-keyword=energy cooperative END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=19 article-no= start-page=11035 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220920 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Immune State Conversion of the Mesenteric Lymph Node in a Mouse Breast Cancer Model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Secondary lymphoid tissues, such as the spleen and lymph nodes (LNs), contribute to breast cancer development and metastasis in both anti- and pro-tumoral directions. Although secondary lymphoid tissues have been extensively studied, very little is known about the immune conversion in mesenteric LNs (mLNs) during breast cancer development. Here, we demonstrate inflammatory immune conversion of mLNs in a metastatic 4T1 breast cancer model. Splenic T cells were significantly decreased and continuously suppressed IFN-gamma production during tumor development, while myeloid-derived suppressor cells (MDSCs) were dramatically enriched. However, T cell numbers in the mLN did not decrease, and the MDSCs only moderately increased. T cells in the mLN exhibited conversion from a pro-inflammatory state with high IFN-gamma expression to an anti-inflammatory state with high expression of IL-4 and IL-10 in early- to late-stages of breast cancer development. Interestingly, increased migration of CD103(+)CD11b(+) dendritic cells (DCs) into the mLN, along with increased (1 -> 3)-beta-D-glucan levels in serum, was observed even in late-stage breast cancer. This suggests that CD103(+)CD11b(+) DCs could prime cancer-reactive T cells. Together, the data indicate that the mLN is an important lymphoid tissue contributing to breast cancer development. en-copyright= kn-copyright= en-aut-name=ShigehiroTsukasa en-aut-sei=Shigehiro en-aut-mei=Tsukasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UenoMaho en-aut-sei=Ueno en-aut-mei=Maho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KijihiraMayumi en-aut-sei=Kijihira en-aut-mei=Mayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakahashiRyotaro en-aut-sei=Takahashi en-aut-mei=Ryotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UmemuraChiho en-aut-sei=Umemura en-aut-mei=Chiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TahaEman A. en-aut-sei=Taha en-aut-mei=Eman A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KurosakaChisaki en-aut-sei=Kurosaka en-aut-mei=Chisaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AsayamaMegumi en-aut-sei=Asayama en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MurakamiHiroshi en-aut-sei=Murakami en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=11 ORCID= en-aut-name=FutamiJunichiro en-aut-sei=Futami en-aut-mei=Junichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MasudaJunko en-aut-sei=Masuda en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Research Institute for Biomedical Sciences, Tokyo University of Science kn-affil= affil-num=2 en-affil=Department of Applied Chemistry and Biotechnology, Faculty of Engineering, Okayama University kn-affil= affil-num=3 en-affil=Department of Applied Chemistry and Biotechnology, Faculty of Engineering, 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=Division of Medical Bioengineering, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Division of Medical Bioengineering, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Department of Applied Chemistry and Biotechnology, Faculty of Engineering, Okayama University kn-affil= affil-num=8 en-affil=Department of Applied Chemistry and Biotechnology, Faculty of Engineering, 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 Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=12 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=13 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=breast cancer cells kn-keyword=breast cancer cells en-keyword=dendritic cells kn-keyword=dendritic cells en-keyword=mesenteric lymph node kn-keyword=mesenteric lymph node en-keyword=myeloid-derived suppressor cells kn-keyword=myeloid-derived suppressor cells END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=17 article-no= start-page=6436 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220826 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Design and Implementation of SEMAR IoT Server Platform with Applications en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, rapid developments of Internet of Things (IoT) technologies have increased possibilities of realizing smart cities where collaborations and integrations of various IoT application systems are essential. However, IoT application systems have often been designed and deployed independently without considering the standards of devices, logics, and data communications. In this paper, we present the design and implementation of the IoT server platform called Smart Environmental Monitoring and Analytical in Real-Time (SEMAR) for integrating IoT application systems using standards. SEMAR offers Big Data environments with built-in functions for data aggregations, synchronizations, and classifications with machine learning. Moreover, plug-in functions can be easily implemented. Data from devices for different sensors can be accepted directly and through network connections, which will be used in real-time for user interfaces, text files, and access to other systems through Representational State Transfer Application Programming Interface (REST API) services. For evaluations of SEMAR, we implemented the platform and integrated five IoT application systems, namely, the air-conditioning guidance system, the fingerprint-based indoor localization system, the water quality monitoring system, the environment monitoring system, and the air quality monitoring system. When compared with existing research on IoT platforms, the proposed SEMAR IoT application server platform offers higher flexibility and interoperability with the functions for IoT device managements, data communications, decision making, synchronizations, and filters that can be easily integrated with external programs or IoT applications without changing the codes. The results confirm the effectiveness and efficiency 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=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=PuspitaningayuPradini en-aut-sei=Puspitaningayu en-aut-mei=Pradini kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KuribayashiMinoru en-aut-sei=Kuribayashi en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Department of Informatic and Computer, Politeknik Elektronika Negeri Surabaya kn-affil= affil-num=6 en-affil=Department of Electrical Engineering, National Taiwan Normal University kn-affil= en-keyword=Internet of Things kn-keyword=Internet of Things en-keyword=server platform kn-keyword=server platform en-keyword=SEMAR kn-keyword=SEMAR en-keyword=IoT application system kn-keyword=IoT application system en-keyword=sensor kn-keyword=sensor en-keyword=MQTT kn-keyword=MQTT en-keyword=REST API kn-keyword=REST API END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=4 article-no= start-page=359 end-page=371 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Therapeutic Approaches Targeting miRNA in Systemic Lupus Erythematosus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Systemic lupus erythematosus (SLE) is a potentially fatal systemic autoimmune disease, and its etiology involves both genetic and environmental factors such as sex hormone imbalance, genetic predisposition, epigenetic regulation, and immunological factors. Dysregulation of microRNA (miRNA) is suggested to be one of the epigenetic factors in SLE. miRNA is a 22-nucleotide single-stranded noncoding RNA that contributes to post-transcriptional modulation of gene expression. miRNA targeting therapy has been suggested to be useful for the treatment of cancers and other diseases. Gene knockout and miRNA targeting therapy have been demonstrated to improve SLE disease activity in mice. However, these approaches have not yet reached the level of clinical application. miRNA targeting therapy is limited by the fact that each miRNA has multiple targets. In addition, the expression of certain miRNAs may differ among cell tissues within a single SLE patient. This limitation can be overcome by targeted delivery and chemical modifications. In the future, further research into miRNA chemical modifications and delivery systems will help us develop novel therapeutic agents for SLE. en-copyright= kn-copyright= en-aut-name=Hiramatsu-AsanoSumie en-aut-sei=Hiramatsu-Asano en-aut-mei=Sumie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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 Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=systemic lupus erythematosus kn-keyword=systemic lupus erythematosus en-keyword=miRNA kn-keyword=miRNA en-keyword=miRNA targeting therapy kn-keyword=miRNA targeting therapy END start-ver=1.4 cd-journal=joma no-vol=42 cd-vols= no-issue= article-no= start-page=108280 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202206 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Developing a dataset for the expected anthropogenic mercury release in China in response to the Minamata convention on mercury en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper contains supplementary data in support of a research paper published [1] regarding the expected anthropogenic mercury release in China in response to the Minamata Convention on Mercury (MCM). The dataset provided within this article contains a set of excel spreadsheets. Each spreadsheet contains filtered (collected) and analysed data, i.e., parameters, collected data, calculated and summarized results for mercury distribution by the category of mineral production, intentional uses, secondary metal production, extraction and combustion, and waste treatment in a specific year. The collected (filtered) data in this article consist of the input factor (IF), activity rate data (ARD), output scenario (OS), initial distribution factor (iDF), and redistribution factor (rDF). IF was from the default IF in the United Nations Environment Programme (UNEP) Toolkit Level 2 and published scientific papers. ARD was obtained from the U.S. Geological Survey database, China Statistical Yearbooks, and published scientific papers. The OS content was from the default OS in the UNEP Toolkit Level 2 and published scientific papers. iDF was from the default distribution factor (DF) in the UNEP Toolkit Level 2 and published scientific papers. rDF was from published scientific paper. The mercury input was calculated using IF and ARD. The mercury release to different media in the initial distribution step was calculated using the mercury input and iDF. The release of mercury to the final sinks in the redistribution step was calculated using the amount of sector-specific treatment/disposal, product or by-product, and rDF. The dataset with combination of the collected (filtered) and analyzed data can contribute to an understanding of differences in anthropogenic mercury release before and after implementation of the MCM, especially considering technology transformation in China. Government policymakers involved in hazardous waste management, especially those working on MCM, and engineers and scientists interested in hazardous waste management may benefit from these data. The data can be used for identifying the environmental impact of anthropogenic mercury release before and after the MCM in China. The data can facilitate the creation of strategic management policies for mercury as the MCM is implemented in China. 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=TakaokaMasaki en-aut-sei=Takaoka en-aut-mei=Masaki 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 Engineering, Kyoto University kn-affil= en-keyword=Anthropogenic activity kn-keyword=Anthropogenic activity en-keyword=Mercury release kn-keyword=Mercury release en-keyword=Minamata convention on mercury kn-keyword=Minamata convention on mercury en-keyword=Technology transformation kn-keyword=Technology transformation END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=918226 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220713 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Examining the Role of Low Temperature in Satsuma Mandarin Fruit Peel Degreening via Comparative Physiological and Transcriptomic Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Peel degreening is the most conspicuous aspect of fruit ripening in many citrus fruits because of its importance for marketability. In this study, peel degreening in response to propylene (an ethylene analog) and at varying storage temperatures was characterized in Satsuma mandarin (Citrus unshiu Marc.) fruit. Propylene treatment triggered rapid peel degreening (within 4-6 days), indicated by an increase in the citrus color index (CCI) and chlorophyll loss. Peel degreening was also observed in fruit at 10 degrees C and 15 degrees C after 28-42 days, with gradual CCI increase and chlorophyll reduction. However, fruit at 5 degrees C, 20 degrees C, and 25 degrees C remained green, and no substantial changes in peel CCI and chlorophyll content were recorded during the 42-day storage duration. The transcriptomes of peels of fruit treated with propylene for 4 days and those stored at varying temperatures for 28 days were then analyzed by RNA-Seq. We identified three categories of differentially expressed genes that were regulated by (i) propylene (and by analogy, ethylene) alone, (ii) low temperature (5 degrees C, 10 degrees C, or 15 degrees C vs. 25 degrees C) alone, and (iii) either propylene or low temperature. Gene-encoding proteins associated with chlorophyll degradation (such as CuSGR1, CuNOL, CuACD2, CuCAB2, and CuLHCB2) and a transcription factor (CuERF114) were differentially expressed by propylene or low temperature. To further examine temperature-induced pathways, we also monitored gene expression during on-tree fruit maturation vs. postharvest. The onset of on-tree peel degreening coincided with autumnal drops in field temperatures, and it was accompanied by differential expression of low temperature-regulated genes. On the contrary, genes that were exclusively regulated by propylene (such as CuCOPT1 and CuPOX-A2) displayed insignificant expression changes during on-tree peel degreening. These findings indicate that low temperatures could be involved in the fruit ripening-related peel degreening independently of ethylene. en-copyright= kn-copyright= en-aut-name=MitaloOscar W. en-aut-sei=Mitalo en-aut-mei=Oscar W. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AsicheWilliam O. en-aut-sei=Asiche en-aut-mei=William O. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KangSeung W. en-aut-sei=Kang en-aut-mei=Seung W. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EzuraHiroshi en-aut-sei=Ezura en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AkagiTakashi en-aut-sei=Akagi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KuboYasutaka en-aut-sei=Kubo en-aut-mei=Yasutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UshijimaKoichiro en-aut-sei=Ushijima en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Research and Development, Del Monte Kenya Ltd kn-affil= affil-num=3 en-affil=Graduate School of Life and Environmental Sciences, University of Tsukuba kn-affil= affil-num=4 en-affil=Graduate School of Life and Environmental Sciences, University of Tsukuba kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=chlorophyll kn-keyword=chlorophyll en-keyword=citrus kn-keyword=citrus en-keyword=degreening kn-keyword=degreening en-keyword=ethylene kn-keyword=ethylene en-keyword=RNA-Seq kn-keyword=RNA-Seq en-keyword=on-tree kn-keyword=on-tree en-keyword=storage kn-keyword=storage END start-ver=1.4 cd-journal=joma no-vol=98 cd-vols= no-issue=6 article-no= start-page=227 end-page=282 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220610 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=On the origin and evolution of the asteroid Ryugu: A comprehensive geochemical perspective en-subtitle= kn-subtitle= en-abstract= kn-abstract=Presented here are the observations and interpretations from a comprehensive analysis of 16 representative particles returned from the C-type asteroid Ryugu by the Hayabusa2 mission. On average Ryugu particles consist of 50% phyllosilicate matrix, 41% porosity and 9% minor phases, including organic matter. The abundances of 70 elements from the particles are in close agreement with those of CI chondrites. Bulk Ryugu particles show higher δ18O, Δ17O, and ε54Cr values than CI chondrites. As such, Ryugu sampled the most primitive and least-thermally processed protosolar nebula reservoirs. Such a finding is consistent with multi-scale H-C-N isotopic compositions that are compatible with an origin for Ryugu organic matter within both the protosolar nebula and the interstellar medium. The analytical data obtained here, suggests that complex soluble organic matter formed during aqueous alteration on the Ryugu progenitor planetesimal (several 10’s of km), <2.6 Myr after CAI formation. Subsequently, the Ryugu progenitor planetesimal was fragmented and evolved into the current asteroid Ryugu through sublimation. en-copyright= kn-copyright= en-aut-name=NAKAMURAEizo en-aut-sei=NAKAMURA

en-title= kn-title=Determination of glutamate using paper-based microfluidic devices with colorimetric detection for food samples en-subtitle= kn-subtitle= en-abstract= kn-abstract=A paper-based device (PAD) capable of colorimetric detection was developed to determine the presence of glutamate in various food samples. The PAD employs an enzymatic reaction with glutamate followed by an oxidation reaction with N-benzoyl leucomethylene blue (BLMB) in the presence of horseradish peroxidase. The designed PAD consists of a sample introduction zone connected to a channel that transports a sample solution to three detection zones. The detection zones contain pre-deposited reagents: glutamate oxidase, horseradish peroxidase, BLMB, a phosphate buffer, and poly(acrylic acid). The PAD is perpendicularly immersed into a sample solution and bent at a right angle using a 3D-printed holder to allow the sample to simultaneously flow into three different detection zones. When the PAD is immersed into a sample containing glutamate, glutamate oxidase produces hydrogen peroxide, which changes the pale blue color of BLMB to a deep blue color in the presence of horseradish peroxidase. Under the optimum conditions, the calibration curve between the logarithm of the glutamate concentrations and the color intensity was linear within a range of from 5 x 10(-6) mol L-1 to 10(-2) and with a correlation coefficient of 0.994. Using this system, the PAD successfully determined glutamate in soup stocks, sauces, snacks, and tomato juice without the need of complicated sample pretreatment. These results agreed with those of a commercially available glutamate assay kit, which was employed as a certification method (t(stat )= 1.95, t(crit )= 2.57). The developed PAD is simple, easy to fabricate, portable, and could be used outside of equipped laboratories to determine the presence of glutamate in food samples. en-copyright= kn-copyright= en-aut-name=DanchanaKaewta en-aut-sei=Danchana en-aut-mei=Kaewta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwasakiHiroshi en-aut-sei=Iwasaki en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OchiaiKenta en-aut-sei=Ochiai en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=KanetaTakashi en-aut-sei=Kaneta en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Chemistry, 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= affil-num=4 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Glutamate kn-keyword=Glutamate en-keyword=Paper-based analytical device kn-keyword=Paper-based analytical device en-keyword=Enzymatic reaction kn-keyword=Enzymatic reaction END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=乳幼児期の喫煙環境の曝露と問題行動 kn-title=Early childhood exposure to maternal smoking and behavioral development en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=AriyoshiMakiko en-aut-sei=Ariyoshi en-aut-mei=Makiko kn-aut-name=有吉真季子 kn-aut-sei=有吉 kn-aut-mei=真季子 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=9 article-no= start-page=eabk0331 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202234 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Vasopressin-oxytocin?type signaling is ancient and has a conserved water homeostasis role in euryhaline marine planarians en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vasopressin/oxytocin (VP/OT)?related peptides are essential for mammalian antidiuresis, sociosexual behavior, and reproduction. However, the evolutionary origin of this peptide system is still uncertain. Here, we identify orthologous genes to those for VP/OT in Platyhelminthes, intertidal planarians that have a simple bilaterian body structure but lack a coelom and body-fluid circulatory system. We report a comprehensive characterization of the neuropeptide derived from this VP/OT-type gene, identifying its functional receptor, and name it the “platytocin” system. Our experiments with these euryhaline planarians, living where environmental salinities fluctuate due to evaporation and rainfall, suggest that platytocin functions as an “antidiuretic hormone” and also organizes diverse actions including reproduction and chemosensory-associated behavior. We propose that bilaterians acquired physiological adaptations to amphibious lives by such regulation of the body fluids. This neuropeptide-secreting system clearly became indispensable for life even without the development of a vascular circulatory system or relevant synapses. en-copyright= kn-copyright= en-aut-name=KobayashiAoshi en-aut-sei=Kobayashi en-aut-mei=Aoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamadaMayuko en-aut-sei=Hamada en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshidaMasa-aki en-aut-sei=Yoshida en-aut-mei=Masa-aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KobayashiYasuhisa en-aut-sei=Kobayashi en-aut-mei=Yasuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsutsuiNaoaki en-aut-sei=Tsutsui en-aut-mei=Naoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SekiguchiToshio en-aut-sei=Sekiguchi en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsukawaYuta en-aut-sei=Matsukawa en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MaejimaSho en-aut-sei=Maejima en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=GingellJoseph J. en-aut-sei=Gingell en-aut-mei=Joseph J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SekiguchiShoko en-aut-sei=Sekiguchi en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HamamotoAyumu en-aut-sei=Hamamoto en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HayDebbie L. en-aut-sei=Hay en-aut-mei=Debbie L. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MorrisJohn F. en-aut-sei=Morris en-aut-mei=John F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=SakamotoTatsuya en-aut-sei=Sakamoto en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 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=15 ORCID= affil-num=1 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Oki Marine Biological Station, Shimane University kn-affil= affil-num=4 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Noto Marine Laboratory, Institute of Nature and Environmental Technology, Division of Marine Environmental Studies, Kanazawa University kn-affil= affil-num=7 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Vertex Pharmaceuticals (Europe) Ltd. kn-affil= affil-num=10 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=11 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=12 en-affil=School of Biological Sciences and Maurice Wilkins Centre for Molecular Biodiscovery, University of Auckland kn-affil= affil-num=13 en-affil=Department of Physiology, Anatomy, and Genetic, Le Gros Clark Building, University of Oxford kn-affil= affil-num=14 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=15 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University, Ushimado kn-affil= END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=9 article-no= start-page=5738 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cholera Outbreaks in India, 2011-2020: A Systematic Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fecal contamination of water sources and open defecation have been linked to cholera outbreaks in India. However, a systematic review on the drivers responsible for these outbreaks has yet to be published. Here, we systematically review the published literature on cholera outbreaks in India between 2011 and 2020. We searched studies in English in three databases (MEDLINE, EMBASE, and Web of Science) and the Integrated Disease Surveillance Program that tracks cholera outbreaks throughout India. Two authors independently extracted data and assessed the quality of the included studies. Quantitative data on the modes of transmission reviewed in this study were assessed for any change over time between 2011-2015 and 2016-2020. Our search retrieved 10823 records initially, out of which 81 full-text studies were assessed for eligibility. Among these 81 studies, 20 were eligible for inclusion in this review. There were 565 reported outbreaks between 2011 and 2020 that led to 45,759 cases and 263 deaths. Outbreaks occurred throughout the year; however, they exploded with monsoons (June through September). In Tamil Nadu, a typical peak of cholera outbreaks was observed from December to January. Seventy-two percent (33,089/45,759) of outbreak-related cases were reported in five states, namely Maharashtra, West Bengal, Punjab, Karnataka, and Madhya Pradesh. Analysis of these outbreaks highlighted the main drivers of cholera including contaminated drinking water and food, inadequate sanitation and hygiene (including open defecation), and direct contact between households. The comparison between 2011-2015 and 2016-2020 showed a decreasing trend in the outbreaks that arose due to damaged water pipelines. Many Indians still struggle with open defecation, sanitation, and clean water access. These issues should be addressed critically. In addition, it is essential to interrupt cholera short-cycle transmission (mediated by households, stored drinking water and foodstuffs) during an outbreak. As cholera is associated with deprivation, socio-economic development is the only long-term solution. en-copyright= kn-copyright= en-aut-name=MuzemboBasilua Andre en-aut-sei=Muzembo en-aut-mei=Basilua Andre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitaharaKei en-aut-sei=Kitahara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DebnathAnusuya en-aut-sei=Debnath en-aut-mei=Anusuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OhnoAyumu en-aut-sei=Ohno en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=MiyoshiShin-Ichi en-aut-sei=Miyoshi en-aut-mei=Shin-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=cholera kn-keyword=cholera en-keyword=outbreak kn-keyword=outbreak en-keyword=water supply kn-keyword=water supply en-keyword=open defecation kn-keyword=open defecation en-keyword=sewage kn-keyword=sewage en-keyword=household kn-keyword=household en-keyword=food kn-keyword=food en-keyword=close contact kn-keyword=close contact en-keyword=behavioral changes kn-keyword=behavioral changes en-keyword=India kn-keyword=India END start-ver=1.4 cd-journal=joma no-vol=226 cd-vols= no-issue=8 article-no= start-page=107026 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Indecomposable integrally closed modules of arbitrary rank over a two-dimensional regular local ring en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this paper, we construct indecomposable integrally closed modules of arbitrary rank over a two-dimensional regular local ring. The modules are quite explicitly constructed from a given complete monomial ideal. We also give structural and numerical results on integrally closed modules. These are used in the proof of indecomposability of the modules. As a consequence, we have a large class of indecomposable integrally closed modules of arbitrary rank whose ideal is not necessarily simple. This extends the original result on the existence of indecomposable integrally closed modules and strengthens the non-triviality of the theory developed by Kodiyalam. en-copyright= kn-copyright= en-aut-name=HayasakaFutoshi en-aut-sei=Hayasaka en-aut-mei=Futoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Environmental and Mathematical Sciences, Okayama University kn-affil= en-keyword=integral closure kn-keyword=integral closure en-keyword=indecomposable module kn-keyword=indecomposable module en-keyword=monomial ideal kn-keyword=monomial ideal en-keyword=regular local ring kn-keyword=regular local ring END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=858747 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mapping of Nematode Resistance in Hexaploid Sweetpotato Using an Next-Generation Sequencing-Based Association Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=The southern root-knot nematode (SRKN; Meloidogyne incognita) is a typical parasitic nematode that affects sweetpotato [Ipomoea batatas (L.) Lam.], causing a significant decrease in crop yield and commercial value. In Japan, the SRKN is classified into 10 races: SP1-SP5, SP6-1, SP6-2, and SP7-SP9, with the dominant race differing according to the cultivation area. Soil insecticides have previously been used to reduce the soil density of SRKNs; however, this practice is both costly and labor intensive. Therefore, the development of SRKN-resistant sweetpotato lines and cultivars is necessary. However, due to the complexity of polyploid inheritance and the highly heterogeneous genomic composition of sweetpotato, genetic information and research for this species are significantly lacking compared to those for other major diploid crop species. In this study, we utilized the recently developed genome-wide association approach, which uses multiple-dose markers to assess autopolyploid species. We performed an association analysis to investigate resistance toward SRKN-SP2, which is the major race in areas with high sweetpotato production in Japan. The segregation ratio of resistant and susceptible lines in the F-1 mapping population derived from the resistant "J-Red" and susceptible "Choshu" cultivars was fitted to 1: 3, suggesting that resistance to SP2 may be regulated by two loci present in the simplex. By aligning the double digest restriction-site associated DNA sequencing reads to the published Ipomoea trifida reference sequence, 46,982 single nucleotide polymorphisms (SNPs) were identified (sequencing depth > 200). The association study yielded its highest peak on chromosome 7 (Chr07) and second highest peak on chromosome 3 (Chr03), presenting as a single-dose in both loci. Selective DNA markers were developed to screen for resistant plants using the SNPs identified on Chr03 and Chr07. Our results showed that SRKN-SP2-resistant plants were selected with a probability of approximately 70% when combining the two selective DNA markers. This study serves as a model for the identification of genomic regions that control agricultural traits and the elucidation of their effects, and is expected to greatly advance marker-assisted breeding and association studies in polyploid crop species. en-copyright= kn-copyright= en-aut-name=ObataNozomi en-aut-sei=Obata en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TabuchiHiroaki en-aut-sei=Tabuchi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KuriharaMiyu en-aut-sei=Kurihara en-aut-mei=Miyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoEiji en-aut-sei=Yamamoto en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShirasawaKenta en-aut-sei=Shirasawa en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MondenYuki en-aut-sei=Monden en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil= Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Kyusyu Okinawa Agricultural Research Center, National Agriculture and Food Research Organization kn-affil= affil-num=3 en-affil=Faculty of Agriculture, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Agriculture, Meiji University kn-affil= affil-num=5 en-affil=Department of Frontier Research and Development, Kazusa DNA Research Institute kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=polyploidy kn-keyword=polyploidy en-keyword=nematode kn-keyword=nematode en-keyword=sweetpotato kn-keyword=sweetpotato en-keyword=resistant cultivar kn-keyword=resistant cultivar en-keyword=breeding kn-keyword=breeding en-keyword=association study kn-keyword=association study END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=2 article-no= start-page=145 end-page=154 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202204 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Construction of a Community Long-term Care Model for Home-based Elderly Individuals en-subtitle= kn-subtitle= en-abstract= kn-abstract=With rapidly aging populations, family care functions can become weakened, and community health services often lack unified standards. A standardized and professional community home-based long-term care model (CHLCM) for the elderly is urgently needed in many regions of China and in other countries. Here, we explored the indicators of the need for a CHLCM among elderly individuals, and we constructed a CHLCM. We created and distributed a questionnaire regarding the requirement of long-term care services, based on a literature review. The two-rounds Delphi method was used, involving 20 experts who were randomly selected from among the medical universities, community health service centers, and nursing homes in Nanning, Guangxi, China. The experts’ enthusiasm rates in the questionnaire’s two rounds were 95% and 100%, respectively. The authentic coefficient of the experts’ consulting was 0.857, and that of the experts’ academic level was 0.835; the judgement coefficient was 0.880 and the familiar coefficient was 0.855. The CHLCM includes service content and an evaluation. The coordination coefficients for the two primary, eight secondary, and 29 tertiary indicators were 0.200, 0.386, and 0.184, respectively (p<0.05). The experts’ enthusiasm and authority were high. The coordination of the experts’ agreement was sufficient, and the analysis results were reliable. The CHLCM includes 29 items that provide a foundation and references for the formulation of concrete indicators and subsequent research. en-copyright= kn-copyright= en-aut-name=QinYi en-aut-sei=Qin en-aut-mei=Yi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LiuLinlin en-aut-sei=Liu en-aut-mei=Linlin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ZhuFanghui en-aut-sei=Zhu en-aut-mei=Fanghui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LuHuazhen en-aut-sei=Lu en-aut-mei=Huazhen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HuangMingliu en-aut-sei=Huang en-aut-mei=Mingliu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Guangxi University of Chinese Medicine kn-affil= affil-num=2 en-affil=Guangxi University of Chinese Medicine kn-affil= affil-num=3 en-affil=Guangxi University of Chinese Medicine kn-affil= affil-num=4 en-affil=Guangxi University of Chinese Medicine kn-affil= affil-num=5 en-affil=Guangxi University of Chinese Medicine kn-affil= en-keyword=community home-based kn-keyword=community home-based en-keyword=long-term care kn-keyword=long-term care en-keyword=elderly kn-keyword=elderly en-keyword=indicator system kn-keyword=indicator system END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=2 article-no= start-page=146 end-page=154 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of Scaled-Up Synthetic Method for Retinoid X Receptor Agonist NEt-3IB Contributing to Sustainable Development Goals en-subtitle= kn-subtitle= en-abstract= kn-abstract=Abstract Small-molecular drugs, which are generally inexpensive compared with biopharmaceuticals and can often be taken orally, may contribute to the Sustainable Development Goals (SDGs) adopted by the United Nations. We previously reported the retinoid X receptor (RXR) agonist 4-(ethyl(3-isobutoxy-4-isopropylphenyl)amino)benzoic acid (NEt-3IB, 1) as a small-molecular drug candidate to replace biopharmaceuticals for the treatment of inflammatory bowel disease. The previous synthetic method to 1 required a large amount of organic solvent and extensive purification. In line with the SDGs, we aimed to develop an environmentally friendly, inexpensive method for the large-scale synthesis of 1. The developed method requires only a hydrophobic ether and EtOH as reaction and extraction solvents. The product was purified by recrystallization twice to afford 99% pure 1 at 100?mmol scale in about 30% yield. The optimized process showed a 35-fold improvement of the E-factor (an index of environmental impact) compared to the original method. This work, which changes the solvent used to environmentally preferable ones based on the existing synthetic method for 1, illustrates how synthetic methods for small-molecular drugs can be adapted and improved to contribute to the SDGs. en-copyright= kn-copyright= en-aut-name=TakamuraYuta en-aut-sei=Takamura en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorishitaKen-ichi en-aut-sei=Morishita en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KikuzawaShota en-aut-sei=Kikuzawa en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeMasaki en-aut-sei=Watanabe en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KakutaHiroki en-aut-sei=Kakuta en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Division of Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Division of Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Division of Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Division of Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Division of Pharmaceutical Sciences, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue= article-no= start-page=191 end-page=205 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211230 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Current Status and Issues of Japanese Language Education for Foreign Technical Interns in the Agricultural Sector :Results of apreliminary study for the development of teaching materials kn-title=農業分野における外国人技能実習生に対する日本語教育の現状と課題ー教材開発に向けた予備調査の結果から一 en-subtitle= kn-subtitle= en-abstract= kn-abstract=外国人技能実習生に対する日本語教育の課題として、介護職以外はH本語能力の受け入れ条件がないこと、受け入れ機関によって日本語教育の時間数や内容が異なること、一般的な初級教材の使用が中心で、専門分野に特化した教材開発には至っていないこと等が挙げられる。本稿では技能の専門領域の中でも「農業分野」における教材閲発のニーズを分析するために、技能実習生を受け入れている企業において実習中のベトナム人技能実習生2人、インドネシア人3人技能実習生に予備調査としてアンケート調査およびインタビュー調査を行った結果を報告する。調査の結果、来H後2年以上を経た現在は、全員から仕事上で日本語が理解できず困ることはあまりないが、渡H帥に農業分野に特化した日本語学習が必要であったという回答があった。さらには、視覚面で理解が促進できる動画教材のニーズが高いことがわかった。今後は、本調査の結果をもとに特定業種の技能実習生向けのICTを利活用した教材開発を進める予定である。 en-copyright= kn-copyright= en-aut-name=MohriTakami en-aut-sei=Mohri en-aut-mei=Takami kn-aut-name=毛利貴美 kn-aut-sei=毛利 kn-aut-mei=貴美 aut-affil-num=1 ORCID= en-aut-name=NakashimaYoshitaka en-aut-sei=Nakashima en-aut-mei=Yoshitaka kn-aut-name=中嶋佳貴 kn-aut-sei=中嶋 kn-aut-mei=佳貴 aut-affil-num=2 ORCID= affil-num=1 en-affil=Institute of Global Resource Development, Okayama University kn-affil=岡山大学グローバル人材育成院 affil-num=2 en-affil=Graduate School of Environmental and life Science, Okayama University kn-affil=岡山大学学術研究院環境生命科学学域 en-keyword=農業分野 kn-keyword=農業分野 en-keyword=外国人技能実習生 kn-keyword=外国人技能実習生 en-keyword=日本語教育 kn-keyword=日本語教育 en-keyword=教材開発 kn-keyword=教材開発 en-keyword=意識調査 kn-keyword=意識調査 END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=2 article-no= start-page=209 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Causal Effect of the Tokyo 2020 Olympic and Paralympic Games on the Number of COVID-19 Cases under COVID-19 Pandemic: An Ecological Study Using the Synthetic Control Method en-subtitle= kn-subtitle= en-abstract= kn-abstract=Previous studies have not assessed the causal effect of the Olympic Games on the spread of pandemics. Using the synthetic control method and the national public city data in Japan recorded from February to September 2021, we estimated the causal effects of the Tokyo 2020 Olympic and Paralympic Games on the number of coronavirus disease 2019 (COVID-19) cases. The difference between the number of COVID-19 cases in Tokyo and a counterfactual "synthetic Tokyo" (created using synthetic control method) after the opening of the Tokyo 2020 Games (23 July 2021) widened gradually and then considerably over time. It was predicted that the Tokyo 2020 Games increased the number of COVID-19 cases in Tokyo by approximately 469.4 per 100,000 population from the opening of the event to 30 September. However, sensitivity analysis of the ratio of the pre- and post-game root mean square prediction errors using regression weights did not suggest robustness. Our results showed that the Tokyo 2020 Games probably increased the number of COVID-19 cases even under preventive regulations; however, the extent of this increase was difficult to estimate clearly due to an overlap with the fifth wave associated with the Delta variant. en-copyright= kn-copyright= en-aut-name=YamamotoNorio en-aut-sei=Yamamoto en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=TsuchihashiYuuki en-aut-sei=Tsuchihashi en-aut-mei=Yuuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= affil-num=1 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Center for Field Epidemic Intelligence, Research, and Professional Development, National Institute of Infectious Diseases kn-affil= affil-num=4 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Tokyo 2020 kn-keyword=Tokyo 2020 en-keyword=Olympic and Paralympic Games kn-keyword=Olympic and Paralympic Games en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=pandemic kn-keyword=pandemic en-keyword=synthetic control method kn-keyword=synthetic control method en-keyword=causal effect kn-keyword=causal effect en-keyword=ecological study kn-keyword=ecological study END start-ver=1.4 cd-journal=joma no-vol=91 cd-vols= no-issue=1 article-no= start-page=58 end-page=67 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220122 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fasciation in Strawberry Floral Organs and Possible Implications for Floral Transition en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fasciation in strawberry is characterized by an enlarged and flattened receptacle, clustering of flowers, and altered inflorescence architecture. However, the developmental process of fasciated flowers remains obscure. In this study, the fasciation incidence and developmental process in the primary fruit and inflorescence architecture were evaluated and compared for the non-susceptible cultivars, ‘Nyoho’ and ‘Sagahonoka’ and one of the most susceptible cultivars, ‘Ai-Berry’. The severity and frequency of flower and inflorescence fasciation was clearly greater in the vigorously growing large plants of ‘Ai-Berry’ compared to small plants and large plants of the other two cultivars. In ‘Ai-Berry’, the deformation of the large shoot apical meristem (SAM) into an oval shape was the initial symptom observed before and during floral transition. Such oval-shaped SAMs often differentiated two or more leaf primordia almost at the same time, which then developed into divided multiple vegetative SAMs before floral transition and linearly-fasciated SAMs during floral transition, respectively. The development of fasciation symptoms was observed after downregulation of FaTFL1. Although inflorescence or receptacle fasciation could be controlled when early and rapid floral induction was achieved by intermittent low-temperature treatment, severe fasciation was observed in late-flowered plants which were either not responsive or not subjected to this treatment. These results indicate that fasciation of floral organs may be triggered and develop during floral transition and that temperature fluctuations around boundary values between floral inhibition to induction may cause a half-finished or slowly processed floral transition and finally result in severe fasciation in vigorously growing ‘Ai-Berry’ plants. en-copyright= kn-copyright= en-aut-name=Thi CamNguyen en-aut-sei=Thi Cam en-aut-mei=Nguyen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SunagawaNaomichi en-aut-sei=Sunagawa en-aut-mei=Naomichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SesumiMiho en-aut-sei=Sesumi en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KitamuraYoshikuni en-aut-sei=Kitamura en-aut-mei=Yoshikuni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaYoshiyuki en-aut-sei=Tanaka en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GotoTanjuro en-aut-sei=Goto en-aut-mei=Tanjuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YasubaKen-ichiro en-aut-sei=Yasuba en-aut-mei=Ken-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshidaYuichi en-aut-sei=Yoshida en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Sciences, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Sciences, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Sciences, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental and Life Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue= article-no= start-page=265 end-page=270 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Life Cycle Impact Analysis of Anthropogenic Mercury Release in Malaysia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Anthropogenic activities have aroused great concern in terms of the negative impact on ecosystems and human health. With rapid industrial development, Malaysia has experienced problems with regard to mercury pollution. Knowledge of the mercury emission and release inventory, and the main factors that ameliorate the environmental impact of anthropogenic activities, will contribute to environmentally sound mercury management, which is becoming increasingly urgent in Malaysia. In this study, inventories for total mercury emission and release in 2019 were devised to understand pollution sources. A life cycle impact assessment was used to identify the major factors contributing to the overall environmental burden. The environmental impact of anthropogenic mercury releases was compared between (sub)source categories. The total mercury input in 2019 was 36.4 t, of which 30.4 t were released to the natural environment under the output scenario of mercury release with no emission control. The respective amounts of 12.7, 1.8, and 15.9 t of mercury were released to air, water, and land. The environmental burden to terrestrial ecosystem imposed by mercury release was higher than that to freshwater and marine ecosystems. The harm to human health was 4,785 DALY, and harm to ecosystem was 0.85 species/y. The category of coal combustion was the largest contributor to the harms of human health (44 % of total impact), followed by cement production (11 % of total impact), and natural gas extraction and combustion (11 % of total impact). The category of gold mining (no amalgamation) was the largest contributor to the harms to ecosystems (76 % of total impact), followed by coal combustion (11 % of total impact). The result of this study can provide a scientific information to policymaker for strategic management of mercury in Malaysia. 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=Muhamad Nabil Fikri bin Abdul Hamid en-aut-sei=Muhamad Nabil Fikri bin Abdul Hamid en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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= END start-ver=1.4 cd-journal=joma no-vol=1 cd-vols= no-issue= article-no= start-page=21 end-page=38 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Kofun culture and the ancient Maya: An introductory comparative archaeology of “Out of Eurasia" kn-title=古墳文化とマヤ文明―比較考古学研究事始― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Both the ancient Maya and Kofun society of Japan were cultural regions formed by Homo sapiens groups after leaving the Eurasian continent more than 10,000 years ago. In this paper, we examine their similarities and differences by comparing perspectives on time and space. The two societies were strati?ed and witnessed the development of monuments that emphasized their verticality. The greatest similarity was the formation of a network society in which local polities coexisted without the institutionalization of centralized leadership at the beginning. Subsequently, the Kofun society adopted the worldview of the Eurasian continent including the concept of the "nation", thereby achieving a new social integration. On the other hand, the ancient Maya, a primary civilization, did not go through the same social process and maintained a sustainable society over a long period of time, maintaining the same form of worldview, monuments, and technological systems. On the similarities rooted in the universality of the human body and cognition, disparity in the process of environmental and social changes, including the direction and distance of "Out of Eurasia", can be seen in the subsequent differences between the ancient Maya and the Japanese archipelago. In this paper, we have illustrated how the similarities and di?erences created diverse directions of culture and history. en-copyright= kn-copyright= en-aut-name=AoyamaKazuo en-aut-sei=Aoyama en-aut-mei=Kazuo kn-aut-name=青山和夫 kn-aut-sei=青山 kn-aut-mei=和夫 aut-affil-num=1 ORCID= en-aut-name=MatsugiTakehiko en-aut-sei=Matsugi en-aut-mei=Takehiko kn-aut-name=松木武彦 kn-aut-sei=松木 kn-aut-mei=武彦 aut-affil-num=2 ORCID= affil-num=1 en-affil=Ibaraki University, College of Humanities and Social Sciences kn-affil= affil-num=2 en-affil=The National Museum of Japanese History, School of Cultural and Social Studies, The Graduate University for Advanced Studies kn-affil= en-keyword=Ancient Maya kn-keyword=Ancient Maya en-keyword=Kofun kn-keyword=Kofun en-keyword=monuments kn-keyword=monuments en-keyword=comparative archaeology kn-keyword=comparative archaeology END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=11 article-no= start-page=1067 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211119 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Current Insights into Atopic March en-subtitle= kn-subtitle= en-abstract= kn-abstract=The incidence of allergic diseases is increasing, and research on their epidemiology, pathophysiology, and the prevention of onset is urgently needed. The onset of allergic disease begins in infancy with atopic dermatitis and food allergy and develops into allergic asthma and allergic rhinitis in childhood; the process is defined as "atopic march ". Atopic march is caused by multiple immunological pathways, including allergen exposure, environmental pollutants, skin barrier dysfunction, type 2 inflammation, and oxidative stress, which promote the progression of atopic march. Using recent evidence, herein, we explain the involvement of allergic inflammatory conditions and oxidative stress in the process of atopic march, its epidemiology, and methods for prevention of onset. en-copyright= kn-copyright= en-aut-name=TsugeMitsuru en-aut-sei=Tsuge en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkedaMasanori en-aut-sei=Ikeda en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 ORCID= affil-num=1 en-affil=Department of Pediatric Acute Diseases, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Epidemiology, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Epidemiology, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=atopic march kn-keyword=atopic march en-keyword=atopic dermatitis kn-keyword=atopic dermatitis en-keyword=food allergy kn-keyword=food allergy en-keyword=allergic asthma kn-keyword=allergic asthma en-keyword=allergic rhinitis kn-keyword=allergic rhinitis en-keyword=skin barrier dysfunction kn-keyword=skin barrier dysfunction en-keyword=alarmin kn-keyword=alarmin en-keyword=group 2 innate lymphoid cells kn-keyword=group 2 innate lymphoid cells en-keyword=type 2 inflammation kn-keyword=type 2 inflammation en-keyword=oxidative stress kn-keyword=oxidative stress en-keyword=specific biomarker kn-keyword=specific biomarker en-keyword=epidemiology kn-keyword=epidemiology en-keyword=phenotype kn-keyword=phenotype en-keyword=early intervention kn-keyword=early intervention en-keyword=emollient kn-keyword=emollient END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=22 article-no= start-page=7631 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211117 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Detection of Lung Cancer Cells in Solutions Using a Terahertz Chemical Microscope en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cancer genome analysis has recently attracted attention for personalized cancer treatment. In this treatment, evaluation of the ratio of cancer cells in a specimen tissue is essential for the precise analysis of the genome. Conventionally, the evaluation takes at least two days and depends on the skill of the pathologist. In our group, a terahertz chemical microscope (TCM) was developed to easily and quickly measure the number of cancer cells in a solution. In this study, an antibody was immobilized on a sensing plate using an avidin-biotin reaction to immobilize it for high density and to improve antibody alignment. In addition, as the detected terahertz signals vary depending on the sensitivity of the sensing plate, the sensitivity was evaluated using pH measurement. The result of the cancer cell detection was corrected using the result of pH measurement. These results indicate that a TCM is expected to be an excellent candidate for liquid biopsies in cancer diagnosis. en-copyright= kn-copyright= en-aut-name=YoshidaYuichi en-aut-sei=Yoshida en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DingXue en-aut-sei=Ding en-aut-mei=Xue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IwatsukiKohei en-aut-sei=Iwatsuki en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TaniizumiKatsuya en-aut-sei=Taniizumi en-aut-mei=Katsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=InoueHirofumi en-aut-sei=Inoue en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WangJin en-aut-sei=Wang en-aut-mei=Jin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=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=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=terahertz kn-keyword=terahertz en-keyword=cancer genomic medicine kn-keyword=cancer genomic medicine en-keyword=cancer cells kn-keyword=cancer cells END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210924 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=ホットスポットクラスター検出のためのソフトウェア開発とEchelon解析に基づく空間データの構造解析に関する研究 kn-title=Studies on Software Development to Detect Hotspot Cluster and Structural Analysis of Spatial Data Based on Echelon Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KajinishiShoji en-aut-sei=Kajinishi en-aut-mei=Shoji kn-aut-name=梶西将司 kn-aut-sei=梶西 kn-aut-mei=将司 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 END start-ver=1.4 cd-journal=joma no-vol=83 cd-vols= no-issue= article-no= start-page=7 end-page=12 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Anthropogenic Mercury Release Flow in China en-subtitle= kn-subtitle= en-abstract= kn-abstract=China is the largest emitter of anthropogenic mercury worldwide. Implementation of the Minamata Convention on Mercury will significantly impact the development, use, and management of mercury resources. Chinese mercury management policies require significant adjustment. There is an urgent need to develop a current national mercury inventory to estimate mercury inputs and outputs by source category, and to clarify the distributions to various environmental scenarios. Here, the mercury releases are quantitatively analysed to facilitate the implementation of strategic mercury management policies in China. First, the mercury inputs and outputs by source categories in 2016 are quantified and then the mercury distributions to various environmental and intermediate sinks are estimated. The total mercury input was 5,116 t in 2016, of which 77% was attributable to mineral production. In total, 3,083 t were released into various environmental and intermediate reservoirs. Of this total, 53.8 % was intentional uses, followed by extraction and combustion (26.5%), and mineral production (19.6 %); 1,501 t were released into air, water, and land, of which extraction and combustion accounted for 48.6 % followed by mineral production (25.7 %) and intentional uses (25.6 %). 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=TakaokaMasaki en-aut-sei=Takaoka en-aut-mei=Masaki 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=Okayama University kn-affil= affil-num=3 en-affil=Kyoto University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=2 article-no= start-page=143 end-page=151 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190910 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Future trends of excess mercury in Asia in response to Minamata Convention on Mercury en-subtitle= kn-subtitle= en-abstract= kn-abstract=Owing to rapid industrialization, Asia has become the main source of mercury emissions and a significant net importer of mercury.
Therefore, the situation regarding excess mercury in Asia needs to be better understood. In this study, mercury flows and excess mercury in 2010?2050 in Asian regions, with a particular focus on China, are assessed under updated assumptions. The excess mercury in China in 2030 and 2050 is estimated to be 125 and 284 tons, respectively. The cumulative excess mercury in China will reach around 10,000 tons in 2050 under the assumption of no export of it in the years 2010?2050. In addition, the year in which mercury reaches a surplus in Asia (excl. China) is estimated to be 2039. The mercury supply in Asia strongly depends on the usage of excess mercury in China. It is estimated that mercury supplies will be insufficient in Asia until at least 2017. These predictions should support decision-making and planning for long-term storage capacity, discussions of regional coordination, securing of technical support, and development of the basic design of related facilities. 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=HamaguchiDaisuke en-aut-sei=Hamaguchi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ZhouYingjun en-aut-sei=Zhou en-aut-mei=Yingjun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujimoriTakashi en-aut-sei=Fujimori en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakaokaMasaki en-aut-sei=Takaoka en-aut-mei=Masaki 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 Engineering, Kyoto University kn-affil= affil-num=3 en-affil=Graduate School of Engineering, Kyoto University kn-affil= affil-num=4 en-affil=Graduate School of Engineering, Kyoto University kn-affil= affil-num=5 en-affil=Graduate School of Engineering, Kyoto University kn-affil= en-keyword=Excess mercury kn-keyword=Excess mercury en-keyword=Long-term strategy kn-keyword=Long-term strategy en-keyword=Scenario analysis kn-keyword=Scenario analysis en-keyword=China kn-keyword=China en-keyword=Asia kn-keyword=Asia END start-ver=1.4 cd-journal=joma no-vol=323 cd-vols= no-issue= article-no= start-page=129089 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The response of anthropogenic mercury release in China to the Minamata Convention on Mercury: A hypothetical expectation en-subtitle= kn-subtitle= en-abstract= kn-abstract=The combination of anthropogenic activities and long-term atmospheric transport has resulted in a sustained increase in global mercury concentrations in air, in water and on land. The Minamata Convention on Mercury (MCM), is a global treaty with the goal of protecting human health and the environment from anthropogenic releases of mercury. This study aimed to quantify the mercury inputs and outputs in China in 2016?2019 according to five source categories and investigate the effect of an accelerated scenario/technology transformation required by the MCM on the subsequent distribution of mercury among environmental and intermediate reservoirs. Mercury releases to natural environment decreased dramatically after the MCM, such that around 840 t of mercury was released to those reservoirs in 2019, which is less than 21% of that in 2016 (1,063 t) when an accelerated scenario/technology transformation (STranf) was taken into consideration. Applying the accelerated STranf can hardly change the total release amount to the natural environment, also can reduce 53 t and 58 t of atmospheric emission in 2018 and 2019 respectively. Atmospheric emission was most sensitive to STranf, followed by emissions to land and water. This is the first attempt to provide a systematic evaluation of the effectiveness of the MCM based on the hypothetical expectations. As the MCM moves into the implementation phase, further information from scientific data and studies is critically needed to support decision-making and management. The results of this study can provide such information, facilitating the creation of strategic management policies for mercury as the MCM is implemented in China. 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=TakaokaMasaki en-aut-sei=Takaoka en-aut-mei=Masaki 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 Engineering, Kyoto University kn-affil= en-keyword=Mercury kn-keyword=Mercury en-keyword=Anthropogenic release kn-keyword=Anthropogenic release en-keyword=Distribution flow kn-keyword=Distribution flow en-keyword=Substance flow analysis kn-keyword=Substance flow analysis en-keyword=Minamata Convention on Mercury kn-keyword=Minamata Convention on Mercury en-keyword=China kn-keyword=China END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue= article-no= start-page=713358 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Harnessing Treg Homeostasis to Optimize Posttransplant Immunity: Current Concepts and Future Perspectives en-subtitle= kn-subtitle= en-abstract= kn-abstract=CD4(+)CD25(+)Foxp3(+) regulatory T cells (Tregs) are functionally distinct subsets of mature T cells with broad suppressive activity and have been shown to play an important role in the establishment of immune tolerance after allogeneic hematopoietic stem cell transplantation (HSCT). Tregs exhibit an activated phenotype from the stage of emigration from the thymus and maintain continuous proliferation in the periphery. The distinctive feature in homeostasis enables Tregs to respond sensitively to small environmental changes and exert necessary and sufficient immune suppression; however, on the other hand, it also predisposes Tregs to be susceptible to apoptosis in the inflammatory condition post-transplant. Our studies have attempted to define the intrinsic and extrinsic factors affecting Treg homeostasis from the acute to chronic phases after allogeneic HSCT. We have found that altered cytokine environment in the prolonged post-HSCT lymphopenia or peri-transplant use of immune checkpoint inhibitors could hamper Treg reconstitution, leading to refractory graft-versus-host disease. Using murine models and clinical trials, we have also demonstrated that proper intervention with low-dose interleukin-2 or post-transplant cyclophosphamide could restore Treg homeostasis and further amplify the suppressive function after HSCT. The purpose of this review is to reconsider the distinctive characteristics of post-transplant Treg homeostasis and discuss how to harness Treg homeostasis to optimize posttransplant immunity for developing a safe and efficient therapeutic strategy.

Recent studies have suggested that dental caries harbor respiratory infections in adults. We investigated the association between dental caries and influenza in children. In this study, 42,812 children aged 2.5 years, 38,540 children aged 5.5 years, and 34,124 children aged 10 years were included in the analysis from the Longitudinal Survey of Newborns in the 21st Century in Japan, which targeted all children born during a certain period in 2001. We used information on dental caries treated at hospitals and clinics in the past year as exposure and influenza as outcome during the observation periods (1.5-2.5, 4.5-5.5, and 9-10 years of age). We performed a log-binomial regression analysis, adjusting for potential confounders, and stratified analysis according to previous dental caries status. The presence of dental caries increased the incidence of influenza in all three target ages compared with the absence of dental caries. The incidence of influenza increased with the presence of current dental caries, regardless of the presence of past dental caries. These associations were observed irrespective of household income. Early detection and treatment of dental caries may reduce the risk of influenza in children. 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=KadowakiTomoka en-aut-sei=Kadowaki en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 ORCID= affil-num=1 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pediatrics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=dental caries kn-keyword=dental caries en-keyword=influenza kn-keyword=influenza en-keyword=birth cohort kn-keyword=birth cohort en-keyword=oral health kn-keyword=oral health END start-ver=1.4 cd-journal=joma no-vol=109 cd-vols= no-issue=11 article-no= start-page=3916 end-page=3928 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021916 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The eco‐evolutionary dynamics of prior selfing rates promote coexistence without niche partitioning under conditions of reproductive interference en-subtitle= kn-subtitle= en-abstract= kn-abstract=1. Pollinator-mediated reproductive interference can occur when two or more plant species share the same pollinators. Recent studies have suggested that prior autonomous selfing mitigates reproductive interference, potentially facilitating coexistence even in the absence of pollination niche partitioning (i.e. the pre-emptive selfing hypothesis). However, whether the evolution of prior selfing promotes coexistence, in the context of the eco-evolutionary dynamics of population size, selfing rates and inbreeding depression, remains poorly understood.
2. We constructed an individual-based model to examine the conditions under which the evolution of prior selfing promotes coexistence in the context of mutual reproductive interference. In the model, two plant species compete by way of mutual reproductive interference, and both have the potential to evolve the capacity for prior autonomous selfing. We expected that purging of deleterious mutations might result in evolutionary rescue, assuming that the strength of inbreeding depression declines as the population selfing rate increases; this would enable inferior competitors to maintain population density through the evolution of prior selfing.
3. Our simulation demonstrated that evolution of prior selfing may promote coexistence, whereas reproductive interference in the absence of such evolution results in competitive exclusion. We found that lower pollinator availability is likely to favour rapid evolutionary shifts to higher prior selfing rates, thereby neutralising the negative effects of reproductive interference in both species. When the strength of inbreeding depression decreased with an increase in the population-level selfing rate, moderate pollinator availability resulted in long-term coexistence in which relative abundance-dependent selection on the prior selfing rate served to intermittently maintain the population density of the inferior competitor.
4. Synthesis. We demonstrate that the evolution of prior selfing may increase population growth rates of inferior competitors and may consequently promote long-term coexistence via an evolutionary rescue. This constitutes a novel mechanism explaining the co-evolutionary coexistence of closely related plant species without niche partitioning, and is consistent with recent studies reporting that closely related species with mixed mating systems can co-occur sympatrically, even under conditions of mutual reproductive interference. en-copyright= kn-copyright= en-aut-name=KatsuharaKoki en-aut-sei=Katsuhara en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TachikiYuuya en-aut-sei=Tachiki en-aut-mei=Yuuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IritaniRyosuke en-aut-sei=Iritani en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UshimaruAtushi en-aut-sei=Ushimaru en-aut-mei=Atushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Human Development and Environment, Kobe University Kobe kn-affil= affil-num=2 en-affil=Department of Biological Sciences Tokyo Metropolitan University Tokyo Japan kn-affil= affil-num=3 en-affil=Interdisciplinary Theoretical and Mathematical Sciences Program (iTHEMS) RIKEN Wako Saitama Japan kn-affil= affil-num=4 en-affil=Graduate School of Human Development and Environment Kobe University Kobe Japan kn-affil= en-keyword=Co-evolution kn-keyword=Co-evolution en-keyword=evolutionary rescue kn-keyword=evolutionary rescue en-keyword=inbreeding depression kn-keyword=inbreeding depression en-keyword=individual-based model kn-keyword=individual-based model en-keyword=mixed mating kn-keyword=mixed mating en-keyword=pollinator-mediated competition kn-keyword=pollinator-mediated competition en-keyword=reproductive ecology kn-keyword=reproductive ecology en-keyword=selfing syndrome kn-keyword=selfing syndrome END start-ver=1.4 cd-journal=joma no-vol=139 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reduction of macrophages by carrageenan decreases oocyst output and modifies local immune reaction in chick cecum with Eimeria tenella en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to evaluate the disease severity and local immune responses in macrophage-depleted chicks with Eimeria tenella. Macrophages were reduced by intraperitoneal injection of a carrageenan solution at 12, 13, and 16 days old, whereas the control group received intraperitoneal phosphate-buffered saline. Both chick groups were orally inoculated with E. tenella sporulated oocysts at 14 days old. Feces were collected daily, which were then quantified for oocysts. The chicks were sacrificed on day 5, and the ceca were collected for histopathological observation. The gene expression levels were measured using real-time quantitative reverse transcription-polymerase chain reaction. Macrophage-depleted chicks have been observed to shed a significantly reduced number of fecal oocysts compared to the infected control group. The parasite burden score in cecum specimens of macrophage-depleted chicks was significantly lower than those of infected control on day 5 after infection. Furthermore, macrophage reduction yielded significantly lower cecum histopathological scores and CD4 expression than those of the infected control group. The expression of interleukin (IL)-18, IL-22, interferon-γ, and inducible nitric oxide synthase was also noted to be significantly upregulated in both infected control and macrophage-depleted chicks compared to uninfected chicks. IL-4, IL-13, IL-17, and perforin expressions were also higher with macrophage depletion than in both control groups. These results suggest that macrophages serve as an invasive gate or a transporting vehicle to the site of first merogony. Furthermore, mononuclear phagocytes may play an important role in local immune responses, thus contributing to parasite development during early E. tenella infection. en-copyright= kn-copyright= en-aut-name=HoDung Thi en-aut-sei=Ho en-aut-mei=Dung Thi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PhamHung Hoang Son en-aut-sei=Pham en-aut-mei=Hung Hoang Son kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AotaWataru en-aut-sei=Aota en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsubayashiMakoto en-aut-sei=Matsubayashi en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsujiNaotoshi en-aut-sei=Tsuji en-aut-mei=Naotoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HatabuToshimitsu en-aut-sei=Hatabu en-aut-mei=Toshimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Veterinary Science, Graduate School of Life and Environmental Sciences, Osaka Prefecture University kn-affil= affil-num=5 en-affil=Department of Parasitology and Tropical Medicine, Kitasato University School of Medicine kn-affil= affil-num=6 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Eimeria tenella kn-keyword=Eimeria tenella en-keyword=Local immune response kn-keyword=Local immune response en-keyword=Macrophage kn-keyword=Macrophage END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=7 article-no= start-page=75224 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210726 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Design and validation of microfluidic parameters of a microfluidic chip using fluid dynamics en-subtitle= kn-subtitle= en-abstract= kn-abstract=The internal fluidic parameters of microfluidic channels must be analyzed to solve fundamental microfluidic problems, including microscale transport problems involving thermal analysis, chemical reactivity, velocity, pressure drop, etc., for developing good-quality chemical and biological products. Therefore, the characterization and optimization of the interaction of chemical and biological solutions through microfluidic channels are vital for fluid flow design and engineering for quality assurance in microfluidic platforms. As the internal structures and kinetics of microfluidic channels are becoming increasingly complex, experiments involving optimal fluidic and transport designs are challenging to perform with high accuracy. However, highly integrated simulation tools can guide researchers without specialized computational fluid backgrounds to design numerical prototypes of highly integrated devices. In this study, a microfluidic chip with two inlet wells and one outlet well was fabricated from polydimethylsiloxane following which simulations were performed using an ANSYS Fluent tool influenced by computational fluid dynamics at a nearly identical scale. The pressure drop and velocity profiles of the interaction of two pH buffer solutions (pH 4 and 10) through the designed microfluidic chip were qualitatively estimated from experimental data analysis and validated with the simulation results obtained from the CFD-influenced ANSYS Fluent tool. en-copyright= kn-copyright= en-aut-name=AhmedFeroz en-aut-sei=Ahmed en-aut-mei=Feroz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshidaYuichi en-aut-sei=Yoshida en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WangJin en-aut-sei=Wang en-aut-mei=Jin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Department of Medical Bioengineering, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Department of Medical Bioengineering, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Department of Medical Bioengineering, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Department of Medical Bioengineering, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Department of Medical Bioengineering, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=8 article-no= start-page=1535 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210727 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Transcriptome Analysis Reveals Key Genes Involved in Weevil Resistance in the Hexaploid Sweetpotato en-subtitle= kn-subtitle= en-abstract= kn-abstract=Because weevils are the most damaging pests of sweetpotato, the development of cultivars resistant to weevil species is considered the most important aspect in sweetpotato breeding. However, the genes and the underlying molecular mechanisms related to weevil resistance are yet to be elucidated. In this study, we performed an RNA sequencing-based transcriptome analysis using the resistant Kyushu No. 166 (K166) and susceptible Tamayutaka cultivars. The weevil resistance test showed a significant difference between the two cultivars at 30 days after the inoculation, specifically in the weevil growth stage and the suppressed weevil pupation that was only observed in K166. Differential expression and gene ontology analyses revealed that the genes upregulated after inoculation in K166 were related to phosphorylation, metabolic, and cellular processes. Because the weevil resistance was considered to be related to the suppression of larval pupation, we investigated the juvenile hormone (JH)-related genes involved in the inhibition of insect metamorphosis. We found that the expression of some terpenoid-related genes, which are classified as plant-derived JHs, was significantly increased in K166. This is the first study involving a comprehensive gene expression analysis that provides new insights about the genes and mechanisms associated with weevil resistance in sweetpotato. en-copyright= kn-copyright= en-aut-name=NokiharaKanoko en-aut-sei=Nokihara en-aut-mei=Kanoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkadaYoshihiro en-aut-sei=Okada en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhataShinichiro en-aut-sei=Ohata en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MondenYuki en-aut-sei=Monden en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Kyushu Okinawa Agricultural Research Center, National Agriculture and Food Research Organization kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=transcriptome kn-keyword=transcriptome en-keyword=RNA-seq kn-keyword=RNA-seq en-keyword=sweetpotato kn-keyword=sweetpotato en-keyword=weevil resistance kn-keyword=weevil resistance en-keyword=juvenile hormones kn-keyword=juvenile hormones en-keyword=terpenes kn-keyword=terpenes END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=8 article-no= start-page=777 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210815 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Identification and Validation of QTLs for Yield and Yield Components under Long-Term Salt Stress Using IR64 CSSLs in the Genetic Background of Koshihikari and Their Backcross Progenies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Unraveling the complex genetic bases and mechanisms underlying salt tolerance is of great importance for developing salt-tolerant varieties. In this study, we evaluated 42 chromosome segment substitution lines (CSSLs) carrying chromosome segments from IR64 on the genetic background of Koshihikari under salt stress. Two CSSLs, SL2007 and SL2038, produced higher plant dry weight and grain yield than did Koshihikari under the stress condition. These CSSLs also showed lower Na+ and Cl- accumulation in the leaf and whole plant at the full heading stage, which might be related to the higher grain yield and yield components. To understand the genetic control of its grain yield and yield components, a SL2007/Koshihikari F-2 population was generated for quantitative trait locus (QTL) analysis. Six QTLs for grain yield and yield-related traits were detected on chromosome 2. Using near-isogenic lines (NILs) from a SL2007/Koshihikari F-5 population, qSTGY2.2 was delimited to a 2.5 Mb region and novel qSTPN2 was delimited to a 0.6 Mb region. We also detected a novel QTL, qSTGF2, for grain filling, which was considered an important contributor to grain yield under salt stress in this CSSL. Our results provide insights into mechanisms conferring grain yield under salinity stress and new genetic resources for cloning and breeding. en-copyright= kn-copyright= en-aut-name=Nguyen SaoMai en-aut-sei=Nguyen Sao en-aut-mei=Mai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Dao DuyHanh en-aut-sei=Dao Duy en-aut-mei=Hanh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakashimaMai en-aut-sei=Nakashima en-aut-mei=Mai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KumamotoKotaro en-aut-sei=Kumamoto en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Nguyen Thi ThuThuy en-aut-sei=Nguyen Thi Thu en-aut-mei=Thuy kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KobataTohru en-aut-sei=Kobata en-aut-mei=Tohru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaitohKuniyuki en-aut-sei=Saitoh en-aut-mei=Kuniyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Agriculture, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Agriculture, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Faculty of Life and Environmental Science, Shimane University kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=QTL kn-keyword=QTL en-keyword=salt tolerance kn-keyword=salt tolerance en-keyword=grain yield kn-keyword=grain yield en-keyword=yield components kn-keyword=yield components en-keyword=reproductive stage kn-keyword=reproductive stage END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=jkab244 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021713 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Chromosome-scale assembly of wild barley accession “OUH602” en-subtitle= kn-subtitle= en-abstract= kn-abstract=Barley (Hordeum vulgare) was domesticated from its wild ancestral form ca. 10,000?years ago in the Fertile Crescent and is widely cultivated throughout the world, except for in tropical areas. The genome size of both cultivated barley and its conspecific wild ancestor is approximately 5?Gb. High-quality chromosome-level assemblies of 19 cultivated and one wild barley genotype were recently established by pan-genome analysis. Here, we release another equivalent short-read assembly of the wild barley accession “OUH602.” A series of genetic and genomic resources were developed for this genotype in prior studies. Our assembly contains more than 4.4?Gb of sequence, with a scaffold N50 value of over 10?Mb. The haplotype shows high collinearity with the most recently updated barley reference genome, “Morex” V3, with some inversions. Gene projections based on “Morex” gene models revealed 46,807 protein-coding sequences and 43,375 protein-coding genes. Alignments to publicly available sequences of bacterial artificial chromosome (BAC) clones of “OUH602” confirm the high accuracy of the assembly. Since more loci of interest have been identified in “OUH602,” the release of this assembly, with detailed genomic information, should accelerate gene identification and the utilization of this key wild barley accession. en-copyright= kn-copyright= en-aut-name=SatoKazuhiro en-aut-sei=Sato en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MascherMartin en-aut-sei=Mascher en-aut-mei=Martin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HimmelbachAxel en-aut-sei=Himmelbach en-aut-mei=Axel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HabererGeorg en-aut-sei=Haberer en-aut-mei=Georg kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SpannaglManuel en-aut-sei=Spannagl en-aut-mei=Manuel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SteinNils en-aut-sei=Stein en-aut-mei=Nils 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=Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) Gatersleben kn-affil= affil-num=3 en-affil=Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) Gatersleben kn-affil= affil-num=4 en-affil=Plant Genome and Systems Biology (PGSB), Helmholtz Center Munich, German Research Center for Environmental Health kn-affil= affil-num=5 en-affil=Plant Genome and Systems Biology (PGSB), Helmholtz Center Munich, German Research Center for Environmental Health kn-affil= affil-num=6 en-affil=Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) Gatersleben kn-affil= en-keyword=genome assembly kn-keyword=genome assembly en-keyword= Hordeum vulgare ssp. spontaneum kn-keyword= Hordeum vulgare ssp. spontaneum en-keyword=OUH602 kn-keyword=OUH602 en-keyword= pseudomolecules kn-keyword= pseudomolecules en-keyword=wild barley kn-keyword=wild barley END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue= article-no= start-page=647684 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210810 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Purification, Characterization, and Gene Expression of Rice Endo-beta-N-Acetylglucosaminidase, Endo-Os en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the endoplasmic reticulum-associated degradation system of plant and animal cells, high-mannose type free N-glycans (HMT-FNGs) are produced from misfolded glycoproteins prior to proteasomal degradation, and two enzymes, cytosolic peptide:N-glycanase (cPNGase) and endo-beta-N-acetylglucosaminidase (endo-beta-GlcNAc-ase), are involved in the deglycosylation. Although the physiological functions of these FNGs in plant growth and development remain to be elucidated, detailed characterization of cPNGase and endo-beta-GlcNAc-ase is required. In our previous work, we described the purification, characterization, and subcellular distribution of some plant endo-beta-GlcNAc-ases and preliminarily reported the gene information of rice endo-beta-GlcNAc-ase (Endo-Os). Furthermore, we analyzed the changes in gene expression of endo-beta-GlcNAc-ase during tomato fruit maturation and constructed a mutant line of Arabidopsis thaliana, in which the two endo-beta-GlcNAc-ase genes were knocked-out based on the Endo-Os gene. In this report, we describe the purification, characterization, amino acid sequence, and gene cloning of Endo-Os in detail. Purified Endo-Os, with an optimal pH of 6.5, showed high activity for high-mannose type N-glycans bearing the Man alpha 1-2Man alpha 1-3Man beta 1 unit; this substrate specificity was almost the same as that of other plant endo-beta-GlcNAc-ases, suggesting that Endo-Os plays a critical role in the production of HTM-FNGs in the cytosol. Electrospray ionization-mass spectrometry analysis of the tryptic peptides revealed 17 internal amino acid sequences, including the C terminus; the N-terminal sequence could not be identified due to chemical modification. These internal amino acid sequences were consistent with the amino acid sequence (UniProt ID: Q5W6R1) deduced from the Oryza sativa cDNA clone AK112067 (gene ID: Os05g0346500). Recombinant Endo-Os expressed in Escherichia coli using cDNA showed the same enzymatic properties as those of native Endo-Os. en-copyright= kn-copyright= en-aut-name=MaedaMegumi en-aut-sei=Maeda en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkamotoNaoko en-aut-sei=Okamoto en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ArakiNode en-aut-sei=Araki en-aut-mei=Node kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KimuraYoshinobu en-aut-sei=Kimura en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Biofunctional Chemistry, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Biofunctional Chemistry, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Tumor Genetics and Biology, Graduate School of Medical Sciences, Kumamoto University kn-affil= affil-num=4 en-affil=Department of Biofunctional Chemistry, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=endo-beta-N-acetylglucosaminidase kn-keyword=endo-beta-N-acetylglucosaminidase en-keyword=free N-glycans kn-keyword=free N-glycans en-keyword=Oryza sativa kn-keyword=Oryza sativa en-keyword=ER associated degradation kn-keyword=ER associated degradation en-keyword=peptide:N-glycanase kn-keyword=peptide:N-glycanase END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=12 article-no= start-page=6430 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210614 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comprehensive Analysis of Risk Factors for Periodontitis Focusing on the Saliva Microbiome and Polymorphism en-subtitle= kn-subtitle= en-abstract= kn-abstract=Few studies have exhaustively assessed relationships among polymorphisms, the microbiome, and periodontitis. The objective of the present study was to assess associations simultaneously among polymorphisms, the microbiome, and periodontitis. We used propensity score matching with a 1:1 ratio to select subjects, and then 22 individuals (mean age +/- standard deviation, 60.7 +/- 9.9 years) were analyzed. After saliva collection, V3-4 regions of the 16S rRNA gene were sequenced to investigate microbiome composition, alpha diversity (Shannon index, Simpson index, Chao1, and abundance-based coverage estimator) and beta diversity using principal coordinate analysis (PCoA) based on weighted and unweighted UniFrac distances. A total of 51 single-nucleotide polymorphisms (SNPs) related to periodontitis were identified. The frequencies of SNPs were collected from Genome-Wide Association Study data. The PCoA of unweighted UniFrac distance showed a significant difference between periodontitis and control groups (p < 0.05). There were no significant differences in alpha diversity and PCoA of weighted UniFrac distance (p > 0.05). Two families (Lactobacillaceae and Desulfobulbaceae) and one species (Porphyromonas gingivalis) were observed only in the periodontitis group. No SNPs showed significant expression. These results suggest that periodontitis was related to the presence of P. gingivalis and the families Lactobacillaceae and Desulfobulbaceae but not SNPs. en-copyright= kn-copyright= en-aut-name=ToyamaNaoki en-aut-sei=Toyama en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuiDaisuke en-aut-sei=Matsui en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KoyamaTeruhide en-aut-sei=Koyama en-aut-mei=Teruhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakatochiMasahiro en-aut-sei=Nakatochi en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MomozawaYukihide en-aut-sei=Momozawa en-aut-mei=Yukihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KuboMichiaki en-aut-sei=Kubo en-aut-mei=Michiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Epidemiology for Community Health and Medicine, Kyoto Prefectural University of Medicine kn-affil= affil-num=4 en-affil=Department of Epidemiology for Community Health and Medicine, Kyoto Prefectural University of Medicine kn-affil= affil-num=5 en-affil=Public Health Informatics Unit, Department of Integrated Health Sciences, Nagoya University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Laboratory for Genotyping Development, RIKEN Center for Integrative Medical Sciences kn-affil= affil-num=7 en-affil=Laboratory for Genotyping Development, RIKEN Center for Integrative Medical Sciences kn-affil= affil-num=8 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=periodontitis kn-keyword=periodontitis en-keyword=microbiota kn-keyword=microbiota en-keyword=single-nucleotide polymorphisms kn-keyword=single-nucleotide polymorphisms END start-ver=1.4 cd-journal=joma no-vol=62 cd-vols= no-issue=3 article-no= start-page=390 end-page=400 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of the redox state in mouse organs following radon inhalation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Radon inhalation activates antioxidative functions in mouse organs, thereby contributing to inhibition of oxidative stress-induced damage. However, the specific redox state of each organ after radon inhalation has not been reported. Therefore, in this study, we evaluated the redox state of various organs in mice following radon inhalation at concentrations of 2 or 20 kBq/m(3) for 1, 3 or 10 days. Scatter plots were used to evaluate the relationship between antioxidative function and oxidative stress by principal component analysis (PCA) of data from control mice subjected to sham inhalation. The results of principal component (PC) 1 showed that the liver and kidney had high antioxidant capacity; the results of PC2 showed that the brain, pancreas and stomach had low antioxidant capacities and low lipid peroxide (LPO) content, whereas the lungs, heart, small intestine and large intestine had high LPO content but low antioxidant capacities. Furthermore, using the PCA of each obtained cluster, we observed altered correlation coefficients related to glutathione, hydrogen peroxide and LPO for all groups following radon inhalation. Correlation coefficients related to superoxide dismutase in organs with a low antioxidant capacity were also changed. These findings suggested that radon inhalation could alter the redox state in organs; however, its characteristics were dependent on the total antioxidant capacity of the organs as well as the radon concentration and inhalation time. The insights obtained from this study could be useful for developing therapeutic strategies targeting individual organs. en-copyright= kn-copyright= en-aut-name=KataokaTakahiro en-aut-sei=Kataoka en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KanzakiNorie en-aut-sei=Kanzaki en-aut-mei=Norie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakodaAkihiro en-aut-sei=Sakoda en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShutoHina en-aut-sei=Shuto en-aut-mei=Hina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YanoJunki en-aut-sei=Yano en-aut-mei=Junki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NaoeShota en-aut-sei=Naoe en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanakaHiroshi en-aut-sei=Tanaka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HanamotoKatsumi en-aut-sei=Hanamoto en-aut-mei=Katsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TeratoHiroaki en-aut-sei=Terato en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MitsunobuFumihiro en-aut-sei=Mitsunobu en-aut-mei=Fumihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YamaokaKiyonori en-aut-sei=Yamaoka en-aut-mei=Kiyonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=3 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=4 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=7 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=8 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=9 en-affil=Advanced Science Research Center, Okayama University kn-affil= affil-num=10 en-affil=Graduate School ofMedicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=radon kn-keyword=radon en-keyword=redox state kn-keyword=redox state en-keyword=oxidative stress kn-keyword=oxidative stress en-keyword=antioxidative function kn-keyword=antioxidative function en-keyword=principal component analysis kn-keyword=principal component analysis END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=1 article-no= start-page=181 end-page=186 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=20080101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Appearance of Multidrug-Resistant Opportunistic Bacteria on the Gingiva During Leukemia Treatment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Dentists generally recognize the importance of periodontal treatment inpatients with leukemia, with the most attention paid to preventing the development of odontogenic infection. For physicians, the worst type of infection is one caused by multidrug-resistant bacteria. Here, we report a patient with an abnormal increase in multidrug-resistant opportunistic bacteria in the gingiva during hematopoietic cell transplantation (HCT).

Methods: A 53-year-old woman receiving HCT for leukemia had an insufficient blood cell count for invasive periodontal treatment before HCT. Even brushing caused difficulties with hemostasis. Therefore, frequent pocket irrigation and local minocycline administration were performed.

Results: The multidrug-resistant opportunistic bacterium Stenotrophomonas maltophilia was detected first in phlegm 2 days before HCT, and it was detected in a gingival smear and a blood sample 7 and I I days after HCT, respectively. The patient developed sepsis on day I I and died 14 days after HCT. Frequent irrigation and local antibiotic application were ineffective against S. maltophilia on the gingiva. Inflammatory gingiva without scaling and root planing showed bleeding tendency, and this interfered with the eradication of this bacterium.

Conclusions: The gingiva in patients undergoing leukemia treatment acts as sites of proliferation and reservoirs for multidrug-resistant opportunistic bacteria. Severe systemic infection by multidrug-resistant bacteria in such patients with leukemia also may involve the gingiva. To prevent abnormal increases in such bacteria on the gingiva, scaling and/or root planing before chemotherapy, which reduces bleeding on brushing during the neutropenic period caused by chemotherapy, may contribute to infection control in such patients, although it was impossible in this case. en-copyright= kn-copyright= en-aut-name=SogaYoshihiko en-aut-sei=Soga en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoTakashi en-aut-sei=Saito en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishimuraFusanori en-aut-sei=Nishimura en-aut-mei=Fusanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshimaruFumihiko en-aut-sei=Ishimaru en-aut-mei=Fumihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MineshibaJunji en-aut-sei=Mineshiba en-aut-mei=Junji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MineshibaFumi en-aut-sei=Mineshiba en-aut-mei=Fumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakayaHirokazu en-aut-sei=Takaya en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SatoHideaki en-aut-sei=Sato en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KudoChieko en-aut-sei=Kudo en-aut-mei=Chieko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KokeguchiSusumu en-aut-sei=Kokeguchi en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TanimotoMitsune en-aut-sei=Tanimoto en-aut-mei=Mitsune kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Pathophysiology ?

The μ-PADs consist of left and right channels that allow the simultaneous measurements of Cr(VI) and total Cr based on the colorimetric reaction of Cr(VI) with 1,5-diphenylcarbazide (DPC). For the determination of Cr(VI), a sample solution was directly reacted with DPC in the left channels whereas total Cr was determined in the right channels, which permitted online oxidation in the pretreatment zone containing cerium (IV) (Ce(IV)) followed by a colorimetric reaction with DPC. We found that the online oxidation of Cr(III) proceeded 100% whereas Ce(IV) inhibited the reaction of Cr(VI) with DPC. Therefore, speciation can be achieved by measuring the Cr(VI) and total Cr in the left and right channels followed by the subtraction of Cr(VI) from total Cr. The limits of detection and quantification were 0.008 and 0.02 mg L?1 for Cr(VI) and 0.07 and 0.1 mg L?1 for Cr(III) or total Cr, respectively. The linear dynamic ranges were 0.02?100 mg L?1 and 0.1?60 mg L?1 for Cr(VI) and Cr(III), respectively. The RSDs were less than 7.5%. The results obtained using μ-PADs were in good agreement with those obtained via ICP-OES with recoveries of 92?108% for Cr(III) and 108?110% for Cr (VI) using μ-PADs, and 106?110% for total Cr using ICP-OES. Thus, the μ-PADs could potentially be utilized for the speciation of chromium in developing countries where environmental pollution and the availability of sophisticated instruments are significant problems. en-copyright= kn-copyright= en-aut-name=MuhammedAbdellah en-aut-sei=Muhammed en-aut-mei=Abdellah kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HussenAhmed en-aut-sei=Hussen en-aut-mei=Ahmed kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanetaTakashi en-aut-sei=Kaneta en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Center for Environmental Science, College of Natural and Computational Sciences, Addis Ababa University kn-affil= affil-num=2 en-affil=Center for Environmental Science, College of Natural and Computational Sciences, Addis Ababa University kn-affil= affil-num=3 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Microfluidic paper-based analytical device kn-keyword=Microfluidic paper-based analytical device en-keyword=Chromium kn-keyword=Chromium en-keyword=Cr(III) kn-keyword=Cr(III) en-keyword=Cr(VI) kn-keyword=Cr(VI) en-keyword=Online oxidation kn-keyword=Online oxidation en-keyword=Speciation kn-keyword=Speciation END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=380 end-page=388 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210131 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A comparison of colorimetric and visual methods for the assessment of masticatory performance with color-changeable chewing gum in older persons en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/purpose
Color-changeable chewing gum is used for the evaluation of masticatory performance. However, it is currently unclear whether colorimetric and visual assessment methods yield consistent results. This study aimed to clarify the consistency between colorimetric and visual methods used for the evaluation of color changes in color-changeable chewing gum.
Materials and methods
The sample comprised 644 older persons (mean age, 75.4?±?6.4 years). The chewing gum was masticated 60 times at the participant's own chewing rate and then expectorated. The color of the chewing gum was evaluated with the ΔE values and a? values, measured using a colorimeter, and the 10 Color Shades (10CSh) and 5 Color Scales (5CSc), using visual evaluation. Spearman's correlation analysis was performed to examine the correlation between the results obtained by the four methods. The significance level was set at α?=?0.05.
Results
The ΔE values, a? values, 10CSh scores, and 5CSc scores were all significantly correlated. The highest correlation coefficient (0.979) was between the ΔE values and a? values. The lowest correlation coefficient (0.847) was between the a? values and 5CSc scores. Decreased masticatory performance was observed with increased age.
Conclusion
Significant correlations were found for all four methods used in the assessment of masticatory performance with color-changeable chewing gum. While visually based assessments are valid, colorimetric methods are more sensitive to smaller changes in masticatory performance. en-copyright= kn-copyright= en-aut-name=KugimiyaYoshihiro

In particular, an analysis of the lesson, “Seasons and plants”, revealed that phenology was helpful in enhancing students’ understanding of the relationship between the seasonal cycle of weather/climate and plant growth and responses to the environment associated with ESD. These practical lessons proved that collaboration between meteorology and botany is valuable for both the promotion of ESD-oriented understanding of the natural environmental systems and cross-cutting consideration of the subject content in science education, providing a promising approach for teacher education. kn-abstract=理科の学問分野である気象学と植物学との連携により,持続可能な開発のための教育(ESD)を志向した自然環境系の理解を目指し,大学の教科・分野横断的な科目における授業実践を行った。最初の試みとして,気象・季節・気候および植物との関連が重要となる理科の教科内容をベースに,学際的な側面を持ついくつかのテーマが見出された。とりわけ,生物季節(フェノロジー)は,ESD に関連した気象・気候の季節サイクルと植物の成長および環境応答との関わりに関する学生の理解を促進するうえで有用であることが,授業分析から示唆された。これらの授業実践から,気象学と植物学との連携が,自然環境系の ESD 的理解の促進のみならず,教科内容構成の分野横断的な検討にも役立ち,教師教育のためのアプローチとして有望である可能性が示された。 en-copyright= kn-copyright= en-aut-name=HARADATaro en-aut-sei=HARADA en-aut-mei=Taro kn-aut-name=原田太郎 kn-aut-sei=原田 kn-aut-mei=太郎 aut-affil-num=1 ORCID= en-aut-name=KATOKuranoshin en-aut-sei=KATO en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 en-keyword=ESD kn-keyword=ESD en-keyword=教科内容構成 (subject contents organization) kn-keyword=教科内容構成 (subject contents organization) en-keyword=東アジアの気候系 (climate system in East Asia) kn-keyword=東アジアの気候系 (climate system in East Asia) en-keyword=生物季節 (phenology) kn-keyword=生物季節 (phenology) en-keyword=園芸学 (horticulture) kn-keyword=園芸学 (horticulture) END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue= article-no= start-page=1 end-page=13 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210322 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Characteristics of the Environmental Concept of the Students Who Aim to Work in the Childcare Field before Taking Classes about Childcare Contents “Environment” kn-title=保育内容「環境」の授業前において保育者志望学生が抱く環境概念の特徴 en-subtitle= kn-subtitle= en-abstract=This study attempts to reveal the characteristics of the environmental concept students who aim to work in the childcare field before they take classes about childcare contents “environment”.

The descriptive data was mainly put into a quantitative analysis and qualitative analysis using text mining. Students’ characteristics is also examined in a comparison with the environmental concepts of current childcare workers.

The resulting high-mannose type (HMT)-FNGs, which carry one GlcNAc residue at the reducing end (GN1-FNGs), are ubiquitously found in developing plant cells. In a previous study, we found that HMT-FNGs assisted in protein folding and inhibited beta-amyloid fibril formation, suggesting a possible biofunction of FNGs involved in the protein folding system. However, whether these HMT-FNGs occur in the ER, an organelle involved in protein folding, remained unclear. On the contrary, we also reported the presence of plant complex type (PCT)-GN1-FNGs, which carry the Lewis(a) epitope at the non-reducing end, indicating that these FNGs had been fully processed in the Golgi apparatus. Since plant ENGase was active toward HMT-N-glycans but not PCT-N-glycans that carry beta 1-2xylosyl and/or alpha 1-3 fucosyl residue(s), these PCT-GN1-FNGs did not appear to be produced from fully processed glycoproteins that harbored PCT-N-glycans via ENGase activity. Interestingly, PCT-GN1-FNGs were found in the extracellular space, suggesting that HMT-GN1-FNGs formed in the cytosol might be transported back to the ER and processed in the Golgi apparatus through the protein secretion pathway. As the first step in elucidating the production mechanism of PCT-GN1-FNGs, we analyzed the structures of free oligosaccharides in plant microsomes and proved that HMT-FNGs (Man(9-7)GlcNAc(1) and Man(9-8)GlcNAc(2)) could be found in microsomes, which almost consist of the ER compartments. en-copyright= kn-copyright= en-aut-name=KatsubeMakoto en-aut-sei=Katsube en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EbaraNatsuki en-aut-sei=Ebara en-aut-mei=Natsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaedaMegumi en-aut-sei=Maeda en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KimuraYoshinobu en-aut-sei=Kimura en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Biofunctional Chemistry, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Biofunctional Chemistry, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Biofunctional Chemistry, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Biofunctional Chemistry, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=free N-glycans kn-keyword=free N-glycans en-keyword=ER-associated degradation kn-keyword=ER-associated degradation en-keyword=peptide:N-glycanase kn-keyword=peptide:N-glycanase en-keyword=endo-beta-N-acetylglucosaminidase kn-keyword=endo-beta-N-acetylglucosaminidase en-keyword=plant glycoproteins kn-keyword=plant glycoproteins END start-ver=1.4 cd-journal=joma no-vol=176 cd-vols= no-issue= article-no= start-page=47 end-page=58 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Developing Lesson Plans Focused on SDGs in Elementary School and Junior High School Social Studies and Integrated Studies: Taking for Example the Development of an ESD Plan for Learning Environmental Issues kn-title=小中学校社会科・総合的な学習の時間におけるSDGsを学ぶ授業づくりの方法― 環境問題を取り上げたESDの単元開発を事例として ― en-subtitle= kn-subtitle= en-abstract= kn-abstract= 本研究は,SDGsについて学ぶ授業を小学校・中学校の社会科や総合的な学習の時間において実践するための授業づくりの方法を,具体的な単元開発を通して提案しようとするものである。開発単元では,環境問題を取り上げ,持続可能な社会の形成という観点から社会の制度や仕組み,自分たちの行動を見直し,今後の社会のあり方についての見通しを持たせる授業を構想した。これまでの研究は,SDGsを教育内容と関連付けることにとどまっていた。SDGsの目標やターゲットの背後にある原理を検討したうえで,それを反映した授業の目標設定や授業構成を提案することで,他のテーマを取り上げた際にも応用可能な授業づくりの方法を示すことができたと考えている。 en-copyright= kn-copyright= en-aut-name=KUWABARAToshinori en-aut-sei=KUWABARA en-aut-mei=Toshinori kn-aut-name=桑原敏典 kn-aut-sei=桑原 kn-aut-mei=敏典 aut-affil-num=1 ORCID= en-aut-name=YOKOGAWAKazunari en-aut-sei=YOKOGAWA en-aut-mei=Kazunari kn-aut-name=横川和成 kn-aut-sei=横川 kn-aut-mei=和成 aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=高橋純一 kn-aut-sei=高橋 kn-aut-mei=純一 aut-affil-num=3 ORCID= affil-num=1 en-affil=Division of Social Studies and Language Education, Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 社会・言語教育学系 affil-num=2 en-affil=Division of Subjects and Related Areas of Education, Graduate School of Education, Hyogo University of Teacher Education kn-affil=兵庫教育大学大学院連合学校教育学研究科 教科教育実践学専攻 affil-num=3 en-affil=Division of Subjects and Related Areas of Education, Graduate School of Education, Hyogo University of Teacher Education, kn-affil=兵庫教育大学大学院連合学校教育学研究科 教科教育実践学専攻 en-keyword=SDGs kn-keyword=SDGs en-keyword=ESD kn-keyword=ESD en-keyword=社会科 kn-keyword=社会科 en-keyword=総合的な学習の時間 kn-keyword=総合的な学習の時間 en-keyword=単元開発 kn-keyword=単元開発 END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=3 article-no= start-page=1024 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genetic Elucidation for Response of Flowering Time to Ambient Temperatures in Asian Rice Cultivars en-subtitle= kn-subtitle= en-abstract= kn-abstract=Climate resilience of crops is critical for global food security. Understanding the genetic basis of plant responses to ambient environmental changes is key to developing resilient crops. To detect genetic factors that set flowering time according to seasonal temperature conditions, we evaluated differences of flowering time over years by using chromosome segment substitution lines (CSSLs) derived from japonica rice cultivars "Koshihikari" x "Khao Nam Jen", each with different robustness of flowering time to environmental fluctuations. The difference of flowering times in 9 years' field tests was large in "Khao Nam Jen" (36.7 days) but small in "Koshihikari" (9.9 days). Part of this difference was explained by two QTLs. A CSSL with a "Khao Nam Jen" segment on chromosome 11 showed 28.0 days' difference; this QTL would encode a novel flowering-time gene. Another CSSL with a segment from "Khao Nam Jen" in the region around Hd16 on chromosome 3 showed 23.4 days" difference. A near-isogenic line (NIL) for Hd16 showed 21.6 days' difference, suggesting Hd16 as a candidate for this QTL. RNA-seq analysis showed differential expression of several flowering-time genes between early and late flowering seasons. Low-temperature treatment at panicle initiation stage significantly delayed flowering in the CSSL and NIL compared with "Koshihikari". Our results unravel the molecular control of flowering time under ambient temperature fluctuations. en-copyright= kn-copyright= en-aut-name=HoriKiyosumi en-aut-sei=Hori en-aut-mei=Kiyosumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaishoDaisuke en-aut-sei=Saisho en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NagataKazufumi en-aut-sei=Nagata en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NonoueYasunori en-aut-sei=Nonoue en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Uehara-YamaguchiYukiko en-aut-sei=Uehara-Yamaguchi en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KanataniAsaka en-aut-sei=Kanatani en-aut-mei=Asaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShuKoka en-aut-sei=Shu en-aut-mei=Koka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HirayamaTakashi en-aut-sei=Hirayama en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YonemaruJun-Ichi en-aut-sei=Yonemaru en-aut-mei=Jun-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FukuokaShuichi en-aut-sei=Fukuoka en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MochidaKeiichi en-aut-sei=Mochida en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=National Agriculture and Food Research Organization, Institute of Crop Science kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=National Agriculture and Food Research Organization, Institute of Crop Science kn-affil= affil-num=4 en-affil=National Agriculture and Food Research Organization, Institute of Crop Science kn-affil= affil-num=5 en-affil=RIKEN Center for Sustainable Resource Science kn-affil= affil-num=6 en-affil=RIKEN Center for Sustainable Resource Science kn-affil= affil-num=7 en-affil=National Agriculture and Food Research Organization, Institute of Crop Science kn-affil= affil-num=8 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=9 en-affil=National Agriculture and Food Research Organization, Institute of Crop Science kn-affil= affil-num=10 en-affil=National Agriculture and Food Research Organization, Institute of Crop Science kn-affil= affil-num=11 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=rice kn-keyword=rice en-keyword=flowering time kn-keyword=flowering time en-keyword=ambient temperature fluctuation kn-keyword=ambient temperature fluctuation en-keyword=chromosome segment substitution line (CSSL) kn-keyword=chromosome segment substitution line (CSSL) en-keyword=quantitative trait locus (QTL) kn-keyword=quantitative trait locus (QTL) END start-ver=1.4 cd-journal=joma no-vol=59 cd-vols= no-issue=1 article-no= start-page=1 end-page=12 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=2020 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Immunocytochemical Analysis of α-Tubulin Distribution Before and After Rapid Axopodial Contraction in the Centrohelid Raphidocystis contractilis en-subtitle= kn-subtitle= en-abstract= kn-abstract=The centrohelid Raphidocystis contractilis is a heliozoan that has many radiating axopodia, each containing a bundle of microtubules. Although the rapid contraction of the axopodia at nearly a video rate (30 frames/s) is induced by mechanical stimuli, the mechanism underlying this phenomenon in R. contractilis has not yet been elucidated. In the present study, we described for the first time an adequate immunocytochemical fixation procedure for R. contractilis and the cellular distribution of α-tubulin before and after rapid axopodial contraction. We developed a flow-through chamber equipped with a micro-syringe pump that allowed the test solution to be injected at a flow rate below the threshold required to induce rapid axopodial contraction. Next, we used this injection method for evaluating the effects of different combinations of two fixatives (paraformaldehyde or glutaraldehyde) and two buffers (phosphate buffer or PHEM) on the morphological structure of the axopodia. A low concentration of glutaraldehyde in PHEM was identified as an adequate fixative for immunocytochemistry. The distribution of α-tubulin before and after rapid axopodial contraction was examined using immunocytochemistry and confocal laser scanning fluorescence microscopy. Positive signals were initially detected along the extended axopodia from the tips to the bases and were distributed in a non-uniform manner within the axopodia. Conversely, after the induction of a rapid axopodial contraction, these positive signals accumulated in the peripheral region of the cell. These results indicated that axopodial microtubules disassemble into fragments and/ or tubulin subunits during rapid axopodial contraction. Therefore, we hypothesize that the mechanism of extremely rapid axopodial contraction accompanied by cytoskeletal microtubule degradation in R. contractilis involves microtubule-severing at multiple sites. en-copyright= kn-copyright= en-aut-name=IkedaRisa en-aut-sei=Ikeda en-aut-mei=Risa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KurokawaMiki en-aut-sei=Kurokawa en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MuraiMomoka en-aut-sei=Murai en-aut-mei=Momoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoNoboru en-aut-sei=Saito en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AndoMotonori en-aut-sei=Ando en-aut-mei=Motonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Laboratory of Cell Physiology, Department of Science Education, Graduate School of Education, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Cell Physiology, Department of Science Education, Graduate School of Education, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Cell Physiology, Department of Science Education, Graduate School of Education, Okayama University kn-affil= affil-num=4 en-affil=Laboratory of Animal Physiology and Pharmacology, Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Laboratory of Cell Physiology, Department of Science Education, Graduate School of Education, Okayama University kn-affil= en-keyword=heliozoa kn-keyword=heliozoa en-keyword=immunocytochemistry kn-keyword=immunocytochemistry en-keyword=microtubule kn-keyword=microtubule en-keyword=glutaraldehyde kn-keyword=glutaraldehyde en-keyword=confocal microscopy kn-keyword=confocal microscopy END start-ver=1.4 cd-journal=joma no-vol=465 cd-vols= no-issue= article-no= start-page=012001 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=2020 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Animal Biotechnology Roles in Livestock Production en-subtitle= kn-subtitle= en-abstract= kn-abstract=Currently, meat and milk productions are significantly increasing especially in Asia. The supply of these products is vital to people's health and well-being, whereas the efficiency of beef production appears to be still lower than other meat productions. Improvements in the quality and functionality of their livestock products, as well as their production efficiency, are required for further production. Animal biotechnologies have contributed to genetic improvement, genetic diversity maintenance of domestic animals, etc. Basic animal biotechnologies, such as artificial insemination and embryo transfer, have been well established and applied as powerful tools for genetic improvement of livestock. In the applications of artificial insemination techniques, the use of sexed semen has been now widely spread, and also efforts are also made in the development of the technology using a small amount of sperm. For embryo transfer, several types of vitrification technologies have been applied to improve pregnancy rates and contributed to the international/domestic supply of livestock embryos. Conventional animal biotechnologies, such as in vitro fertilization and intracellular sperm injection, have been applied to not only livestock production and also human-assisted reproductive medicine. For in-vitro production of embryos in domestic animals, currently, oocytes have been collected from medium or large follicles (3-6 mm or larger in diameter) of ovaries. Although the oocytes derived from small follicles (less than 3 mm in diameter) exist more on the surface of ovaries, the developmental competence of the oocytes has been known to be significantly lower than those from medium follicles. If we could improve the competence of oocytes derived from small follicles significantly, we may be able to increase the number of female gamete resources for in vitro embryo production. Also, the development of techniques for producing transgenic and cloned animals has greatly contributed to the creation of pharmaceuticals and organs for xenotransplantation. Recently, furthermore, genome editing technologies, such as combined use of CRISPR/Cas9 and PiggyBac, have been developed and have made it possible to correct specific parts of the genome and introduce mutations by homologous recombination. In this review, I would like to discuss the application and progress of the above biotechnologies, including our recent research results. en-copyright= kn-copyright= en-aut-name=FunahashiHiroaki en-aut-sei=Funahashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=110 cd-vols= no-issue= article-no= start-page=1 end-page=6 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A comparative gene analysis reveals a diatom-specific SET domain protein family kn-title=遺伝子比較解析による珪藻類特異的なSET ドメインタンパク質ファミリーの同定 en-subtitle= kn-subtitle= en-abstract= kn-abstract= The silica cell walls of diatoms, which exhibit species-spe-cific micro- and nano- patterned structures are promising candidates for applications in nanotechnology. Previous studies revealed a number of silica cell wall-associated proteins involved in silica formation. However, molecular biological analyses toward understanding of diatom cell wall formation have been mostly limited to model diatom species and general silica formation process in diatoms is still incompletely understood. In this study, to gain a compre-hensive insight into diatom silica biomineralization, tran-scriptome data of three diatom species, Nitzschia palea, Achnanthes kuwaitensis and Pseudoleyanella lunata, were newly developed. The reads obtained from RNA sequencing were assembled into 31,946, 60,767 and 38,314 unique transcripts for N. palea, A. kuwaitensis and P. lunata, respectively. In order to identify the diatom-specific genes, three transcriptome data sets developed in this study and the protein-coding gene sets of five genome-sequenced diatoms were compared. The proteins shared only by eight diatom species that are predicted to possess an endoplasmic reticulum (ER)-targeting signal peptide were selected for further analyses. These include proteins showing homology to silicanin-1, a recently reported diatom-specific protein involved in silica formation, as well as a number of SET domain proteins. The SET domain proteins might be novel diatom-specific family of methyltransferases that may reg-ulate the function of silica formation related proteins or long chain polyamines. The genes encoding the diatom-specific SET domain proteins identified in this study, which were shown to respond to silicon were suggested to be implicated in silica biomineralization. en-copyright= kn-copyright= en-aut-name=NemotoMichiko en-aut-sei=Nemoto en-aut-mei=Michiko kn-aut-name=根本理子 kn-aut-sei=根本 kn-aut-mei=理子 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 en-keyword=Biomineralization kn-keyword=Biomineralization en-keyword=Diatom kn-keyword=Diatom en-keyword=Silica kn-keyword=Silica en-keyword=Protein kn-keyword=Protein END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=2 article-no= start-page=250 end-page=266 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210107 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-Term Improvement in Precautions for Flood Risk Mitigation: A Case Study in the Low-Lying Area of Central Vietnam en-subtitle= kn-subtitle= en-abstract= kn-abstract=Local actors appear as inseparable components of the integrated flood risk mitigation strategy in Vietnam. Recognizing this fact, this study examined the long-term improvement in precautions taken by commune authorities and households between two major floods in 1999 and 2017 by applying both quantitative and qualitative methods. Two flood-prone villages were selected for a survey; one in a rural area and the other in a suburban area of Thua Thien Hue Province, central Vietnam. The findings indicate that most villagers doubted the structural works' efficacy and were dissatisfied with the current efforts of local authorities. Households' self-preparation thus became the decisive factor in mitigating risk. While most households have paid greater attention to flood precautions in 2017, others seem to be lagging. Poverty-related barriers were the root causes restraining households in both rural and suburban villages. The suburban riverine residents were further identified as vulnerable by their limitations in upgrading structural measures, which was ascribed to the inconsistency in the ancient town's preservation policy.

Therefore, decoding plant?environment interactions by elucidating plants’ temporal physiological responses to environmental changes throughout their lifespans will facilitate the identification of genetic and environmental factors, timing and pathways that influence complex end-point agronomic traits, such as yield. Here, we discuss the expected role of the life-course approach to monitoring plant and crop health status in improving crop productivity by enhancing the understanding of plant?environment interactions. We review recent advances in analytical technologies for monitoring health status in plants based on multi-omics analyses and strategies for integrating heterogeneous datasets from multiple omics areas to identify informative factors associated with traits of interest. In addition, we showcase emerging phenomics techniques that enable the noninvasive and continuous monitoring of plant growth by various means, including three-dimensional phenotyping, plant root phenotyping, implantable/injectable sensors and affordable phenotyping devices. Finally, we present an integrated review of analytical technologies and applications for monitoring plant growth, developed across disciplines, such as plant science, data science and sensors and Internet-of-things technologies, to improve plant productivity. en-copyright= kn-copyright= en-aut-name=MochidaKeiichi en-aut-sei=Mochida en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiiRyuei en-aut-sei=Nishii en-aut-mei=Ryuei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HirayamaTakashi en-aut-sei=Hirayama en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=School of Information and Data Sciences, Nagasaki University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Genome to phenome kn-keyword=Genome to phenome en-keyword=Life-course approach kn-keyword=Life-course approach en-keyword=Multi-omics kn-keyword=Multi-omics en-keyword=Plant phenomics kn-keyword=Plant phenomics en-keyword=Sensor. kn-keyword=Sensor.

The basal resistance of compatible interactions between R. solani and rice is known to be modulated by some WRKY transcription factors (TFs). However, genes and defense responses involved in incompatible interaction with R. solani remain unexplored, because no such interactions are known in any host plants. Recently, we demonstrated that Bd3‐1, an accession of the model grass Brachypodium distachyon, is resistant to R. solani and, upon inoculation with the fungus, undergoes rapid induction of genes responsive to the phytohormone salicylic acid (SA) that encode the WRKY TFs BdWRKY38 and BdWRKY44. Here, we show that endogenous SA and these WRKY TFs positively regulate this accession‐specific R. solani resistance. In contrast to a susceptible accession (Bd21), the infection process in the resistant accessions Bd3‐1 and Tek‐3 was suppressed at early stages before the development of fungal biomass and infection machinery. A comparative transcriptome analysis during pathogen infection revealed that putative WRKY‐dependent defense genes were induced faster in the resistant accessions than in Bd21. A gene regulatory network (GRN) analysis based on the transcriptome dataset demonstrated that BdWRKY38 was a GRN hub connected to many target genes specifically in resistant accessions, whereas BdWRKY44 was shared in the GRNs of all three accessions. Moreover, overexpression of BdWRKY38 increased R. solani resistance in Bd21. Our findings demonstrate that these resistant accessions can activate an incompatible host response to R. solani, and BdWRKY38 regulates this response by mediating SA signaling. en-copyright= kn-copyright= en-aut-name=KouzaiYusuke en-aut-sei=Kouzai en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimizuMinami en-aut-sei=Shimizu en-aut-mei=Minami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InoueKomaki en-aut-sei=Inoue en-aut-mei=Komaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Uehara‐YamaguchiYukiko en-aut-sei=Uehara‐Yamaguchi en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahagiKotaro en-aut-sei=Takahagi en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakayamaRisa en-aut-sei=Nakayama en-aut-mei=Risa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuuraTakakazu en-aut-sei=Matsuura en-aut-mei=Takakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MoriIzumi C. en-aut-sei=Mori en-aut-mei=Izumi C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HirayamaTakashi en-aut-sei=Hirayama en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AbdelsalamSobhy S.

Pta6605 has multiple clusters of chemotaxis genes including cheA, a gene encoding a histidine kinase, cheY, a gene encoding a response regulator, mcp, a gene for a methyl-accepting chemotaxis protein, as well as flagellar and pili biogenesis genes. However, only two major chemotaxis gene clusters, cluster I and cluster II, possess cheA and cheY. Deletion mutants of cheA or cheY were constructed to evaluate their possible role in Pta6605 chemotaxis and virulence. Motility tests and a chemotaxis assay to known attractant demonstrated that cheA2 and cheY2 mutants were unable to swarm and to perform chemotaxis, whereas cheA1 and cheY1 mutants retained chemotaxis ability almost equal to that of the wild-type (WT) strain. Although WT and cheY1 mutants of Pta6605 caused severe disease symptoms on host tobacco leaves, the cheA2 and cheY2 mutants did not, and symptom development with cheA1 depended on the inoculation method. These results indicate that chemotaxis genes located in cluster II are required for optimal chemotaxis and host plant infection by Pta6605 and that cluster I may partially contribute to these phenotypes. en-copyright= kn-copyright= en-aut-name=TumewuStephany Angelia en-aut-sei=Tumewu en-aut-mei=Stephany Angelia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OgawaYujiro en-aut-sei=Ogawa en-aut-mei=Yujiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkamotoTakumi en-aut-sei=Okamoto en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SugiharaYuka en-aut-sei=Sugihara en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamadaHajime en-aut-sei=Yamada en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TaguchiFumiko en-aut-sei=Taguchi en-aut-mei=Fumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuiHidenori en-aut-sei=Matsui en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamamotoMikihiro en-aut-sei=Yamamoto en-aut-mei=Mikihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NoutoshiYoshiteru en-aut-sei=Noutoshi en-aut-mei=Yoshiteru 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= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Agriculture, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Agriculture, Okayama University 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 and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=9 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=10 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Bacterial virulence kn-keyword=Bacterial virulence en-keyword=cheA kn-keyword=cheA en-keyword=Chemotaxis kn-keyword=Chemotaxis en-keyword=cheY kn-keyword=cheY en-keyword=Flagellar motility kn-keyword=Flagellar motility en-keyword=Pseudomonas kn-keyword=Pseudomonas END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=22 article-no= start-page=e14640 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201123 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Alteration of chemokine production in bovine endometrial epithelial and stromal cells under heat stress conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=After parturition, cows frequently develop uterine bacterial infections, resulting in the onset of endometritis. To eliminate the bacteria, bovine endometrial cells secrete chemokines, such as IL-6 and MCP1, which attract macrophages (M Phi s) to the subepithelial stroma. These attracted M Phi s are not only involved in bacterial elimination but also the orchestration of inflammation and tissue repair. These immune responses aid in the recovery from endometritis; however, the recovery from endometritis takes longer in summer than in any other season. Based on these findings, we hypothesized that heat stress (HS) affects the chemokine production in endometrial cells. To confirm this hypothesis, we compared IL-6 and MCP1 production induced by lipopolysaccharide (LPS) in bovine endometrial epithelial and stromal cells under normal (38.5 degrees C) and HS conditions (40.5 degrees C). In the endometrial epithelial cells, IL-6 production stimulated by LPS was significantly (p < .05) suppressed under HS conditions. MCP1 production in endometrial epithelial cells was not detected under both the control and HS conditions regardless of the presence of LPS. Moreover, LPS significantly (p < .05) stimulated IL-6 and MCP1 production in endometrial stromal cells. Moreover, HS significantly (p < .05) enhanced their production compared to that under the control conditions. In addition, HS did not affect the migration ability of M Phi s; however, the supernatant of the endometrial stromal cells cultured under the HS condition significantly (p < .05) attracted the M Phi s when compared to the control condition. These results suggest that HS disrupts chemokine production in two types of endometrial cells and alters the distribution of M Phi s in the endometrium during the summer. en-copyright= kn-copyright= en-aut-name=SakaiShunsuke en-aut-sei=Sakai en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HatabuToshimitsu en-aut-sei=Hatabu en-aut-mei=Toshimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamamotoYuki en-aut-sei=Yamamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KimuraKoji en-aut-sei=Kimura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=chemokine kn-keyword=chemokine en-keyword=cow kn-keyword=cow en-keyword=endometrial cells kn-keyword=endometrial cells en-keyword=endometritis kn-keyword=endometritis en-keyword=heat stress kn-keyword=heat stress END start-ver=1.4 cd-journal=joma no-vol=2020 cd-vols= no-issue=9 article-no= start-page=093H02 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200920 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Improved method for measuring low-concentration radium and its application to the Super-Kamiokande Gadolinium project en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chemical extraction using a molecular recognition resin named "Empore Radium Rad Disk" was developed to improve sensitivity for the low concentration of radium (Ra).

The sensitivity on the 10(-1) mBq level was achieved using a high-purity germanium detector. This improved method was applied to determine Ra-226 in Gd-2(SO4)(3)center dot 8H(2)O which will be used in the Super-Kamiokande Gadolinium project.

In this study, we investigated changes in prehospital EMS activity and transport times during the COVID-19 pandemic. All patients transported by EMS in the city of Okayama from March?May 2019 or March?May 2020 were included. Interfacility transports were excluded. The primary outcome was the time from a patient’s first emergency call until hospital arrival (total prehospital time). Secondary outcomes included three segments of total prehospital time: the response time, on-scene time, and transportation time. Total prehospital time and the durations of each segment were compared between corresponding months in 2020 (COVID19-affected) and 2019 (control). The results showed that total prehospital times in April 2020 were significantly higher than those in 2019 (33.8 ± 11.6 vs. 32.2 ± 10.8 min, p < 0.001). Increases in total prehospital time were caused by longer response time (9.3 ± 3.8 vs. 8.7 ± 3.7 min, p < 0.001) and on-scene time (14.4 ± 7.9 vs. 13.5 ± 6.2min, p < 0.001). The COVID-19 pandemic was thus shown to affect EMS and delayed arrival/response even in a minimally affected region. A system to minimize transportation delays should be developed for emerging pandemics. en-copyright= kn-copyright= en-aut-name=AgetaKohei en-aut-sei=Ageta en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamadaTaihei en-aut-sei=Yamada en-aut-mei=Taihei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YakushijiHiromasa en-aut-sei=Yakushiji en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=emergency medical services kn-keyword=emergency medical services en-keyword=health care system kn-keyword=health care system en-keyword=emergency transport kn-keyword=emergency transport en-keyword=coronavirus kn-keyword=coronavirus en-keyword=infection kn-keyword=infection END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=11 article-no= start-page=3158 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Organic Matter Clogging Results in Undeveloped Hardpan and Soil Mineral Leakage in the Rice Terraces in the Philippine Cordilleras en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rice terraces in Cordillera, Philippines, a world cultural heritage site, are threatened by the risk of collapse. It is crucial to manage these rice terraces for their conservation, while simultaneously practicing traditional farming. We examined the soil environment and investigated its effects on rice terrace conservation, by focusing on the hardpan condition; infiltration process, which is related to the collapse of rice terraces; and soil nutrition conditions in these sites. Field survey and soil analysis revealed that in areas where the hardpan was not sufficiently developed and water infiltration was effectively suppressed, organic matter content was significantly high, suggesting organic matter clogging. In these rice terraces, the amounts of P, K, Ca, and Mn were significantly low, showing the mineral leaching under reductive soil conditions. Therefore, hardpan formation, rather than organic matter clogging, is essential for the suppression of infiltration and prevention of potential terrace collapse. Because hardpan formation or organic matter clogging cannot be identified from the surface of flooded rice paddies, it is difficult to identify the influencing factor. Thus, we suggest that the hard soil layer should be checked before the planting season and drainage is allowed after the cropping season in the rainy season. en-copyright= kn-copyright= en-aut-name=KurozumiTomoyo en-aut-sei=Kurozumi en-aut-mei=Tomoyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoriYasushi en-aut-sei=Mori en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=O-HowMilagros en-aut-sei=O-How en-aut-mei=Milagros kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Universal Harvester Inc. kn-affil= en-keyword=rice terrace kn-keyword=rice terrace en-keyword=hardpan kn-keyword=hardpan en-keyword=infiltration kn-keyword=infiltration en-keyword=organic matter kn-keyword=organic matter en-keyword=clogging kn-keyword=clogging en-keyword=Philippine Cordillera kn-keyword=Philippine Cordillera END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=1 article-no= start-page=14889 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200910 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Identification of effector candidate genes of Rhizoctonia solani AG-1 IA expressed during infection in Brachypodium distachyon en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rhizoctonia solani is a necrotrophic phytopathogen belonging to basidiomycetes. It causes rice sheath blight which inflicts serious damage in rice production. The infection strategy of this pathogen remains unclear. We previously demonstrated that salicylic acid-induced immunity could block R. solani AG-1 IA infection in both rice and Brachypodium distachyon. R. solani may undergo biotrophic process using effector proteins to suppress host immunity before necrotrophic stage. To identify pathogen genes expressed at the early infection process, here we developed an inoculation method using B. distachyon which enables to sample an increased amount of semi-synchronous infection hyphae. Sixty-one R. solani secretory effector-like protein genes (RsSEPGs) were identified using in silico approach with the publicly available gene annotation of R. solani AG-1 IA genome and our RNA-sequencing results obtained from hyphae grown on agar medium. Expression of RsSEPGs was analyzed at 6, 10, 16, 24, and 32 h after inoculation by a quantitative reverse transcription-polymerase chain reaction and 52 genes could be detected at least on a single time point tested. Their expressions showed phase-specific patterns which were classified into 6 clusters. The 23 RsSEPGs in the cluster 1-3 and 29 RsSEPGs in the cluster 4-6 are expected to be involved in biotrophic and necrotrophic interactions, respectively. en-copyright= kn-copyright= en-aut-name=AbdelsalamSobhy S.

However, the important regulators and pathways involved in natural peel degreening remain largely unknown. To determine how natural peel degreening is regulated in lemon fruit (Citrus limon), we studied transcriptome and physiochemical changes in the flavedo in response to ethylene treatment and low temperatures. Treatment with ethylene induced rapid peel degreening, which was strongly inhibited by the ethylene antagonist, 1-methylcyclopropene (1-MCP). Compared with 25 degrees C, moderately low storage temperatures of 5-20 degrees C also triggered peel degreening. Surprisingly, repeated 1-MCP treatments failed to inhibit the peel degreening induced by low temperature. Transcriptome analysis revealed that low temperature and ethylene independently regulated genes associated with chlorophyll degradation, carotenoid metabolism, photosystem proteins, phytohormone biosynthesis and signalling, and transcription factors. Peel degreening of fruit on trees occurred in association with drops in ambient temperature, and it coincided with the differential expression of low temperature-regulated genes. In contrast, genes that were uniquely regulated by ethylene showed no significant expression changes during on-tree peel degreening. Based on these findings, we hypothesize that low temperature plays a prominent role in regulating natural peel degreening independently of ethylene in citrus fruit. en-copyright= kn-copyright= en-aut-name=MitaloOscar W. en-aut-sei=Mitalo en-aut-mei=Oscar W. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtsukiTakumi en-aut-sei=Otsuki en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkadaRui en-aut-sei=Okada en-aut-mei=Rui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ObitsuSaeka en-aut-sei=Obitsu en-aut-mei=Saeka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasudaKanae en-aut-sei=Masuda en-aut-mei=Kanae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HojoYuko en-aut-sei=Hojo en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuuraTakakazu en-aut-sei=Matsuura en-aut-mei=Takakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MoriIzumi C. en-aut-sei=Mori en-aut-mei=Izumi C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AbeDaigo en-aut-sei=Abe en-aut-mei=Daigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=AsicheWilliam O. en-aut-sei=Asiche en-aut-mei=William O. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AkagiTakashi en-aut-sei=Akagi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KuboYasutaka en-aut-sei=Kubo en-aut-mei=Yasutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=8 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=9 en-affil=National Agriculture and Food Research Organization, Shikoku Research Station kn-affil= affil-num=10 en-affil=Department of Research and Development, Del Monte Kenya Ltd kn-affil= affil-num=11 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=12 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=13 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=1-methylcyclopropene kn-keyword=1-methylcyclopropene en-keyword=carotenoids kn-keyword=carotenoids en-keyword=chlorophyll kn-keyword=chlorophyll en-keyword=Citrus limon kn-keyword=Citrus limon en-keyword=ethylene kn-keyword=ethylene en-keyword=low temperature kn-keyword=low temperature en-keyword=peel degreening kn-keyword=peel degreening en-keyword=phytohormones kn-keyword=phytohormones en-keyword=transcriptome kn-keyword=transcriptome END start-ver=1.4 cd-journal=joma no-vol=741 cd-vols= no-issue=1 article-no= start-page=140465 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200625 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-term exposure to nitrogen dioxide and natural-cause and cause-specific mortality in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Long-term exposure to air pollution is linked with increased risk of adverse health outcomes, but the evidence for the association between nitrogen dioxide (NO2) and mortality is weak because of the inadequate adjustment of potential confounders and limited spatial resolution of the exposure assessment. Moreover, there are concerns about the independent effects of NO2. Therefore, we examined the association between NO2 long-term exposure and all-cause and cause-specific mortality.
Methods
We included participants who were enrolled in health checkups in Okayama City, Japan, in 2006 or 2007 and were followed until 2016. We used a land-use regression model to estimate the average NO2 concentrations from 2006 to 2007 and allocated them to the participants. We estimated hazard ratios (HRs) for a 10-μg/m3 increase in NO2 levels for all-cause or cause-specific mortality using Cox proportional hazard models.
Results
After excluding the participants who were assigned with outlier exposures, a total of 73,970 participants were included in the analyses. NO2 exposure was associated with increased risk of mortality and the HRs and their confidence intervals were 1.06 (95% CI: 1.02, 1.11) for all-cause, 1.02 (0.96, 1.09) for cardiopulmonary, and 1.36 (1.14, 1.63) for lung cancer mortality. However, the elevated risks became equivocal after the adjustment for fine particulate matter except lung cancer.
Conclusion
Long-term exposure to NO2 was associated with increased risk of all-cause, cardiopulmonary, and lung cancer mortality. The elevated risk for lung cancer was still observable even after adjustment for fine particulate matter. en-copyright= kn-copyright= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KashimaSaori en-aut-sei=Kashima en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Environmental Health Sciences Laboratory, Graduate School for International Development and Cooperation, Hiroshima University kn-affil= en-keyword=Air pollution kn-keyword=Air pollution en-keyword=Epidemiology kn-keyword=Epidemiology en-keyword=Nitrogen dioxide kn-keyword=Nitrogen dioxide en-keyword=Lung cancer kn-keyword=Lung cancer en-keyword=Mortality kn-keyword=Mortality END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=2 article-no= start-page=231 end-page=240 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=2020 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=DNA markers based on retrotransposon insertion polymorphisms can detect short DNA fragments for strawberry cultivar identification en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, DNA markers were developed for discrimination of strawberry (Fragaria × ananassa L.) cultivars based on retrotransposon insertion polymorphisms. We performed a comprehensive genomic search to identify retrotransposon insertion sites and subsequently selected one retrotransposon family, designated CL3, which provided reliable discrimination among strawberry cultivars. Through analyses of 75 strawberry cultivars, we developed eight cultivar-specific markers based on CL3 retrotransposon insertion sites. Used in combination with 10 additional polymorphic markers, we differentiated 35 strawberry cultivars commonly cultivated in Japan. In addition, we demonstrated that the retrotransposon-based markers were effective for PCR detection of DNA extracted from processed food materials, whereas a SSR marker was ineffective. These results indicated that the retrotransposon-based markers are useful for cultivar discrimination for processed food products, such as jams, in which DNA may be fragmented or degraded. en-copyright= kn-copyright= en-aut-name=HirataChiharu en-aut-sei=Hirata en-aut-mei=Chiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WakiTakamitsu en-aut-sei=Waki en-aut-mei=Takamitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimomuraKatsumi en-aut-sei=Shimomura en-aut-mei=Katsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WadaTakuya en-aut-sei=Wada en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaSeiya en-aut-sei=Tanaka en-aut-mei=Seiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IkegamiHidetoshi en-aut-sei=Ikegami en-aut-mei=Hidetoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UchimuraYousuke en-aut-sei=Uchimura en-aut-mei=Yousuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HirashimaKeita en-aut-sei=Hirashima en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakazawaYoshiko en-aut-sei=Nakazawa en-aut-mei=Yoshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkadaKaori en-aut-sei=Okada en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NamaiKiyoshi en-aut-sei=Namai en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TaharaMakoto en-aut-sei=Tahara en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MondenYuki en-aut-sei=Monden en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Fukuoka Agriculture and Forestry Research Center kn-affil= affil-num=2 en-affil=Tochigi Prefectural Agricultural Experiment Station kn-affil= affil-num=3 en-affil=Fukuoka Agriculture and Forestry Research Center kn-affil= affil-num=4 en-affil=Fukuoka Agriculture and Forestry Research Center kn-affil= affil-num=5 en-affil=Graduate School of Bioresource and Bioenvironmental Sciences, Kyushu University kn-affil= affil-num=6 en-affil=Fukuoka Agriculture and Forestry Research Center kn-affil= affil-num=7 en-affil=Fukuoka Agriculture and Forestry Research Center kn-affil= affil-num=8 en-affil=Fukuoka Agriculture and Forestry Research Center kn-affil= affil-num=9 en-affil=Tochigi Prefectural Agricultural Experiment Station kn-affil= affil-num=10 en-affil=Tochigi Prefectural Agricultural Experiment Station kn-affil= affil-num=11 en-affil=Tochigi Prefectural Agricultural Experiment Station kn-affil= affil-num=12 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=13 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Fragaria × ananassa kn-keyword=Fragaria × ananassa en-keyword=high-throughput sequencing kn-keyword=high-throughput sequencing en-keyword=PCR product kn-keyword=PCR product en-keyword=processed foods kn-keyword=processed foods en-keyword=retrotransposon insertion polymorphisms kn-keyword=retrotransposon insertion polymorphisms END start-ver=1.4 cd-journal=joma no-vol=43 cd-vols= no-issue=8 article-no= start-page=1288 end-page=1291 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202008 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Low Viability of Cholera Toxin-Producing Vibrio cholerae O1 in the Artificial Low Ionic Strength Aquatic Solution en-subtitle= kn-subtitle= en-abstract= kn-abstract=It has been well known that Vibrio cholerae inhabit in environmental water. As many patients infected with cholera toxin-producing V. cholerae O1 (toxigenic V. cholerae O1) emerge in Kolkata, India, it has been thought that toxigenic V. cholerae O1 is easily detected in environmental water in Kolkata. However, we could not isolate toxigenic V. cholerae O1 from environmental water in Kolkata, though NAG Vibrio (generic name of V. cholerae non-O1/non-O139) is constantly detected. To clear the reason for the non-isolation of toxigenic V. cholerae O1, we examined the viability of V. cholera O1 and NAG Vibrios in the artificial low ionic strength aquatic solution. We found that the viability of toxigenic V. cholerae O1 in the solution is low, but that of NAG Vibrios is high. Subsequently, we examined the viability of NAG Vibrios possessing cholera toxin gene (ctx) in the same condition and found that the viability of these NAG Vibrios is low. These results indicate that the existence of ctx in V. cholerae affects the viability of V. cholerae in the aquatic solution used in this experiment. We thought that there was closely relation between the low viability of toxigenic V. cholerae O1 in the artificial low ionic strength aquatic solution and the low frequency of isolation of the strain from environmental water. en-copyright= kn-copyright= en-aut-name=PaulSubha Sankar en-aut-sei=Paul en-aut-mei=Subha Sankar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakahashiEizo en-aut-sei=Takahashi en-aut-mei=Eizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ChowdhuryGoutam en-aut-sei=Chowdhury en-aut-mei=Goutam kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MizunoTamaki en-aut-sei=Mizuno en-aut-mei=Tamaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=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=Department of Health Pharmacy, Yokohama University of Pharmacy kn-affil= affil-num=3 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences of Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences of Okayama University kn-affil= affil-num=6 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=7 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=8 en-affil=Collaborative Research Center of Okayama University for Infectious Diseases in India kn-affil= en-keyword=Vibrio cholerae kn-keyword=Vibrio cholerae en-keyword=cholera toxin kn-keyword=cholera toxin en-keyword=aquatic solution kn-keyword=aquatic solution en-keyword=viability kn-keyword=viability END start-ver=1.4 cd-journal=joma no-vol=39 cd-vols= no-issue=3 article-no= start-page=117 end-page=122 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Oral administration of the probiotic bacterium Lactobacillus acidophilus strain L-55 modulates the immunological parameters of the laying hen inoculated with a Newcastle disease virus-based live attenuated vaccine en-subtitle= kn-subtitle= en-abstract= kn-abstract=Probiotic supplements containing living bacteria have attracted interest as a potential source of health benefits for humans and livestock. The aim of this study was to determine whether administration of Lactobacillus acidophilus strain L-55 (LaL-55) enhances the immune response among chicks exposed to a Newcastle disease virus (NDV)-based live attenuated vaccine. Oral administration of LaL-55 augmented the elevation in the total numbers of leukocytes and lymphocytes following inoculation with the NDV-based live attenuated vaccine. Monocyte counts increased after LaL-55 administration independent of inoculation with the NDV vaccine. Among chicks that were administered LaL-55, there was a dose-dependent increase in the NK cell activity measured by a 51Cr release assay at 2 weeks after the secondary NDV vaccine inoculation. Two weeks after the secondary inoculation with the NDV vaccine, interferon (IFN)-γ-mRNA expression was significantly elevated in mononuclear splenocytes from chicks that were administered LaL-55. Meanwhile, LaL-55 administration did not change the mRNA levels of IFN-α, IFN-β, and interleukin-1β. These results may suggest that coadministration of LaL-55 with an NDV vaccine augments the immune response against the virus. Therefore, LaL-55 may help protect against viral diseases in poultry. en-copyright= kn-copyright= en-aut-name=HoDung Thi en-aut-sei=Ho en-aut-mei=Dung Thi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HatabuToshimitsu en-aut-sei=Hatabu en-aut-mei=Toshimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SunadaYosuke en-aut-sei=Sunada en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KondoYasuhiro en-aut-sei=Kondo en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Research & Development, Ohayo Dairy Products Co., Ltd. kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Lactobacillus acidophilus L-55 kn-keyword=Lactobacillus acidophilus L-55 en-keyword=chicken kn-keyword=chicken en-keyword=Newcastle disease vaccine kn-keyword=Newcastle disease vaccine en-keyword=immunomodulatory kn-keyword=immunomodulatory END start-ver=1.4 cd-journal=joma no-vol=240 cd-vols= no-issue=3 article-no= start-page=032001 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=2019 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Numerical study of air-entraining and submerged vortices in a pump sump en-subtitle= kn-subtitle= en-abstract= kn-abstract=Numerical detection of harmful vortices in pump sumps, such as an air-entraining vortex (AEV) and a submerged vortex (SMV), is crucially important to develop the drain pump machinery. We performed numerical simulations of the benchmark experiments of the pump sump conducted by Matsui et al. (2006 and 2016) using the OpenFOAM and compared the simulation results with the experimental data considering the effects of turbulence model, grid density and detection method of the vortices. We studied the threshold of the gas-liquid volume fraction of the VOF method and the second invariant of velocity gradient tensor to identify AEV and SMV. The methods proposed in the present paper were found to be very effective for the detection of the vortices, and the simulation results by RANS with the SST k-omega model successfully reproduced the experimental data. LES with the Smagorinsky model, however, was sensitive to the grid system and difficult to reproduce the experimental data even for the finest grid system having 3.7 million cells in the present study. en-copyright= kn-copyright= en-aut-name=YanaseShinichiro en-aut-sei=Yanase en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamasakiRyo en-aut-sei=Yamasaki en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KouchiToshinori en-aut-sei=Kouchi en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HosodaShunsuke en-aut-sei=Hosoda en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NagataYasunori en-aut-sei=Nagata en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShunjiHiguchi en-aut-sei=Shunji en-aut-mei=Higuchi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawabeToshihiko en-aut-sei=Kawabe en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakamiToshihiro en-aut-sei=Takami en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Mechanical and Systems Engineering, Okayama University kn-affil= affil-num=2 en-affil=Technical Division, Tsurumi Manufacturing Co. kn-affil= affil-num=3 en-affil=Department of Mechanical and Systems Engineering, Okayama University kn-affil= affil-num=4 en-affil=Department of Mechanical and Systems Engineering, Okayama University kn-affil= affil-num=5 en-affil=Department of Mechanical and Systems Engineering, Okayama University kn-affil= affil-num=6 en-affil=Technical Division, Tsurumi Manufacturing Co. kn-affil= affil-num=7 en-affil=Technical Division, Tsurumi Manufacturing Co. kn-affil= affil-num=8 en-affil=Department of Mechanical and Systems Engineering, Okayama University of Science kn-affil= END start-ver=1.4 cd-journal=joma no-vol=58 cd-vols= no-issue= article-no= start-page=177 end-page=186 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202010 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Continuing surgical education of non-technical skills en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
The non-technical skills for surgeons (NOTSS) system was developed as a tool to assess surgical skills for patient safety during surgery. This study aimed to develop a NOTSS-based training system for surgical trainees to acquire non-technical skills using a chest surgery scenario in a wet lab.
Materials and methods
Trainees were categorized into three subgroups according to the years of experience as follows: Level A: 6 years or more; Level B: 3?5 years; and Level C: 1?2 years. Three stages of surgical procedure were designed: 1. chest wall resection and right upper lobe lobectomy, 2. right middle lobe sleeve lobectomy, and 3. right lower lobe lobectomy. One instructor was assigned to each operation table, who evaluated each participant's NOTSS scores consisting of 16 elements.
Results
When comparing average NOTSS score of all the three procedures, significant differences were observed between Level A, B, and C trainees. As an example of varying elements by procedure, Level A trainees demonstrated differences in Situation Awareness, and a significant difference was observed in Level C trainees regarding the elements of Decision Making. On the contrary, no significant difference was observed among Level B trainees. In the comparison between first-time and experienced participants, a significant improvement was observed in some elements in Level B and C trainees.
Conclusion
This study highlights the usefulness and feasibility of the NOTSS scoring system for surgeons with different experiences and the effectiveness of providing feedback to trainees during intraoperative handoffs in a wet lab. en-copyright= kn-copyright= en-aut-name=YamaneMasaomi en-aut-sei=Yamane en-aut-mei=Masaomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SuzukiEtsuji en-aut-sei=Suzuki en-aut-mei=Etsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AokageKeiju en-aut-sei=Aokage en-aut-mei=Keiju kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SohJunichi en-aut-sei=Soh en-aut-mei=Junichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HayamaMakio en-aut-sei=Hayama en-aut-mei=Makio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HiramiYuji en-aut-sei=Hirami en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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=10 ORCID= affil-num=1 en-affil=Departments of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Departments of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Thoracic Surgery, National Cancer Center Hospital East kn-affil= affil-num=5 en-affil=Departments of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Division of Thoracic Surgery, Department of Surgery, Kindai University Faculty of Medicine kn-affil= affil-num=7 en-affil=Department of Thoracic Surgery, Japanese Red Cross Okayama Hospital kn-affil= affil-num=8 en-affil=Department of General Thoracic Surgery, National Hospital Organization Okayama Medical Center kn-affil= affil-num=9 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Departments of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Non-technical skills kn-keyword=Non-technical skills en-keyword=Patient safety kn-keyword=Patient safety en-keyword=Thoracic surgery kn-keyword=Thoracic surgery END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=4 article-no= start-page=285 end-page=291 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202008 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparison of Two Different Intensive Care Unit Systems for Severely Ill Children in Japan: Data from the JaRPAC Registry en-subtitle= kn-subtitle= en-abstract= kn-abstract=The importance of centralizing treatment services for severely ill children has been well established, but such entralization remains difficult in Japan. We aimed to compare the trauma and illness severity and mortality of children admitted to two common types of ICUs for children. According to the type of management and disposition of the medical provider, we classified ICUs as pediatric ICUs [PICUs] or general ICUs, and analyzed differences in endogenous and exogenous illness settings between them. Overall, 1,333 pediatric patients were included, with 1,143 patients admitted to PICUs and 190 patients to general ICUs. The Pediatric Cerebral Performance Category score (PCPC) at discharge was significantly lower in the PICU group (adjusted OR: 0.45; 95%CI: 0.23-0.88). Death and unfavorable neurological outcomes occurred less often in the PICU group (adjusted OR: 0.29; 95%CI: 0.14-0.60). However, when limited to exogenous illness, PCPC scores (adjusted OR: 0.38; 95%CI: 0.07-1.99) or death/unfavorable outcomes (adjusted OR: 0.72; 95%CI: 0.08-6.34) did not differ between the groups. PCPC deterioration and overall sequelae/death rates were lower in PICUs for children with endogenous illnesses, although the outcomes of exogenous illness were similar between the 2 unit types. Further studies on the necessity of centralization are warranted. en-copyright= kn-copyright= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaitouHiromichi en-aut-sei=Naitou en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=NosakaNobuyuki en-aut-sei=Nosaka en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoHirotsugu en-aut-sei=Yamamoto en-aut-mei=Hirotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OsakoTakaaki en-aut-sei=Osako en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=the JaRPAC Study Group en-aut-sei=the JaRPAC Study Group en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Emergency, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Emergency, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pediatrics, Cedars-Sinai Medical Center kn-affil= affil-num=5 en-affil=Department of Emergency, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Emergency, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Emergency, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil= kn-affil= en-keyword=kids kn-keyword=kids en-keyword=critical care kn-keyword=critical care en-keyword=mortality kn-keyword=mortality en-keyword=morbidity kn-keyword=morbidity en-keyword=centralization kn-keyword=centralization END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=10 article-no= start-page=4872 end-page=4877 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20131210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Monodisperse polylactide microcapsules with a single aqueous core prepared via spontaneous emulsification and solvent diffusion en-subtitle= kn-subtitle= en-abstract= kn-abstract=A simple approach to preparing monodisperse poly(D,L-lactide) (PDLLA) microcapsules with a single aqueous core is developed. The method is based on automatic water-in-oil-in-water double emulsion formation from oil-in-water single emulsion via spontaneous emulsification which voluntarily disperses part of continuous aqueous phase into the dispersed oil phase dissolving oil-soluble amphiphilic diblock copolymer, poly(D,L-lactide)-b-poly(2-dimethylaminoethyl methacylate)(PDLLA-b-PDMAEMA), followed by coalescence of tiny water droplets within the polymer droplets, coupled with quick precipitation of polymers by diluting the emulsion with water. In this study, we have investigated the effect of PDLLA to PDLLA-b-PDMAEMA ratios and flow rates of each solution during preparing the emulsion on the final morphology and the size of the microcapsules. It was found that the polymer blend ratio played a crucial role in determining internal structure of the microcapsules. The microcapsules size decreased with the increment of the flow rate ratios of the continuous phase to the dispersed phase and eventually reached 10 μm, while maintaining narrow size distribution. In addition, we have demonstrated that the microcapsules can encapsulate both hydrophilic and hydrophobic compounds during the formation. 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=KimuraYukitaka en-aut-sei=Kimura en-aut-mei=Yukitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= affil-num=1 en-affil=Department of Applied Chemistry and Biotechnology, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Material and Energy Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Applied Chemistry and Biotechnology, Graduate School of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=10 article-no= start-page=3713 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200525 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Caries Increment and Salivary Microbiome during University Life: A Prospective Cohort Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=The purpose of this 3-year prospective cohort study was to explore the relationship between an increase in dental caries and oral microbiome among Japanese university students. We analyzed 487 students who volunteered to receive oral examinations and answer baseline (2013) and follow-up (2016) questionnaires. Of these students, salivary samples were randomly collected from 55 students at follow-up and analyzed using next-generation sequencing. Students were divided into two groups: increased group (Delta decayed, missing, and filled teeth (Delta DMFT) score increased during the 3-year period) and non-increased group (Delta DMFT did not increase). Thirteen phyla, 21 classes, 32 orders, 48 families, 72 genera, and 156 species were identified. Microbial diversity in the increased group (n = 14) was similar to that in the non-increased group (n = 41). Relative abundances of the family Prevotellaceae (p = 0.007) and genera Alloprevotella (p = 0.007) and Dialister (p = 0.039) were enriched in the increased group compared with the non-increased group. Some bacterial taxonomic clades were differentially present between the two groups. These results may contribute to the development of new dental caries prevention strategies, including the development of detection kits and enlightenment activities for these bacteria. en-copyright= kn-copyright= en-aut-name=Uchida-FukuharaYoko en-aut-sei=Uchida-Fukuhara en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IslamMd Monirul en-aut-sei=Islam en-aut-mei=Md Monirul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KataokaKota en-aut-sei=Kataoka en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Taniguchi-TabataAyano en-aut-sei=Taniguchi-Tabata en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FukuharaDaiki en-aut-sei=Fukuhara en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ToyamaNaoki en-aut-sei=Toyama en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KobayashiTerumasa en-aut-sei=Kobayashi en-aut-mei=Terumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujimoriKohei en-aut-sei=Fujimori en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SawadaNanami en-aut-sei=Sawada en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IwasakiYoshiaki en-aut-sei=Iwasaki en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Advanced Research Center for Oral and Craniofacial Sciences, Okayama University Dental School kn-affil= affil-num=5 en-affil=Department of Preventive Dentistry, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Preventive Dentistry, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Health Service Center, Okayama University kn-affil= affil-num=12 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=salivary microbiome kn-keyword=salivary microbiome en-keyword=sequence analysis kn-keyword=sequence analysis en-keyword=young adult kn-keyword=young adult en-keyword=dental caries kn-keyword=dental caries en-keyword=saliva kn-keyword=saliva en-keyword=oral health kn-keyword=oral health END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=2 article-no= start-page=87 end-page=95 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=2020 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Propagation and Floral Induction of Transplant for Forcing Long-term Production of Seasonal Flowering Strawberries in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=In Japan, over 95% of the acreage is covered with plastic to force June-bearing (seasonal flowering, SF) strawberry cultivars to produce fruit from late fall to early summer. During the late 1960s, a forcing technique was developed that advanced flower bud initiation to late summer and prevented the transplants from becoming dormant during winter. This new forcing technique involved nitrogen starvation of nursery plants to induce floral initiation. Until about 1980, strawberry growers in Japan used runner plants produced in waiting beds, but most transplants are now produced in plastic pots under rain shelters to avoid soil-borne diseases. Recently, the use of tray plants produced from hanging runner cuttings has become popular. To induce early floral initiation, the following artificial low temperature (LT) treatments have been established: (1) “Yarei”, a combination of a short day with solar radiation and LT under darkness in cooling facilities (Yarei-ko); (2) “Kaburei”, continuous dark-LT with refrigeration facilities including industrial warehouses; and (3) “Kanketsu-reizo”, intermittent LT storage. An overview of the technologies applied to plant propagation and the control of floral initiation of Japanese SF cultivars is provided in this review. en-copyright= kn-copyright= en-aut-name=YoshidaYuichi en-aut-sei=Yoshida en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimotoToshi en-aut-sei=Nishimoto en-aut-mei=Toshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Nara Prefecture Agricultural Research and Development Center kn-affil= END start-ver=1.4 cd-journal=joma no-vol=138 cd-vols= no-issue= article-no= start-page=105654 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200531 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Enhanced expression of nicotinamide nucleotide transhydrogenase (NNT) and its role in a human T cell line continuously exposed to asbestos en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effects of asbestos fibers on human immune cells have not been well documented. We have developed a continuously exposed cell line model using the human T-lymphotropic virus 1 (HTLV-1)-immortalized human T cell line MT-2. Sublines continuously exposed to chrysotile (CH) or crocidolite (CR) showed acquired resistance to asbestos-induced apoptosis following transient and high-dose re-exposure with fibers. These sublines in addition to other immune cells such as natural killer cells or cytotoxic T lymphocytes exposed to asbestos showed a reduction in anti-tumor immunity. In this study, the expression of genes and molecules related to antioxidative stress was examined. Furthermore, complexes related to oxidative phosphorylation were investigated since the production of reactive oxygen species (ROS) is important when considering the effects of asbestos in carcinogenesis and the mechanisms involved in resistance to asbestos-induced apoptosis. In sublines continuously exposed to CH or CR, the expression of thioredoxin decreased. Interestingly, nicotinamide nucleotide transhydrogenase (NNT) expression was markedly enhanced. Thus, knockdown of NNT was then performed. Although the knockdown clones did not show any changes in proliferation or occurrence of apoptosis, these clones showed recovery of ROS production with returning NADPH/NADP+ ratio that increased with decreased production of ROS in continuously exposed sublines. These results indicated that NNT is a key factor in preventing ROS-induced cytotoxicity in T cells continuously exposed to asbestos. Considering that these sublines showed a reduction in anti-tumor immunity, modification of NNT may contribute to recovery of the anti-tumor effects in asbestos-exposed T cells. en-copyright= kn-copyright= en-aut-name=YamamotoShoko en-aut-sei=Yamamoto en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LeeSuni en-aut-sei=Lee en-aut-mei=Suni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuzakiHidenori en-aut-sei=Matsuzaki en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Kumagai-TakeiNaoko en-aut-sei=Kumagai-Takei en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshitomeKei en-aut-sei=Yoshitome en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SadaNagisa en-aut-sei=Sada en-aut-mei=Nagisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShimizuYurika en-aut-sei=Shimizu en-aut-mei=Yurika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ItoTastsuo en-aut-sei=Ito en-aut-mei=Tastsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NishimuraYasumitsu en-aut-sei=Nishimura en-aut-mei=Yasumitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OtsukiTakemi en-aut-sei=Otsuki en-aut-mei=Takemi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Hygiene, Kawasaki Medical School kn-affil= affil-num=2 en-affil=Department of Hygiene, Kawasaki Medical School kn-affil= affil-num=3 en-affil=Department of Life Science, Faculty of Life and Environmental Science, Prefectural University of Hiroshima kn-affil= affil-num=4 en-affil=Department of Hygiene, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of Hygiene, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of Biophysical Chemistry, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Pathophysiology-Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Hygiene, Kawasaki Medical School kn-affil= affil-num=9 en-affil=Department of Hygiene, Kawasaki Medical School kn-affil= affil-num=10 en-affil=Department of Hygiene, Kawasaki Medical School kn-affil= en-keyword=Asbestos kn-keyword=Asbestos en-keyword=Continuous exposure kn-keyword=Continuous exposure en-keyword=Oxidative phosphorylation kn-keyword=Oxidative phosphorylation en-keyword=T cell kn-keyword=T cell en-keyword=nicotinamide nucleotide transhydrogenase (NNT) kn-keyword=nicotinamide nucleotide transhydrogenase (NNT) 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=2020 dt-pub=20200325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=イネ根の伸長に関与する二つの遺伝子のマッピングと機能解析 kn-title=Mapping and functional characterization of two genes involved in root development of rice en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=YuEn en-aut-sei=Yu en-aut-mei=En kn-aut-name=余恩 kn-aut-sei=余 kn-aut-mei=恩 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=1388 end-page=1405 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=How Networks Among Frontline Offices Influence Regulatory Enforcement : Diffusion and Justification of Interpretation of Risk en-subtitle= kn-subtitle= en-abstract= kn-abstract=Street‐level interpretation and enforcement are critical to defining the meaning of law. To understand street‐level regulatory decisions, prior studies have highlighted internal office conditions, neglecting the influence that peer offices can have. This study examines the role of horizontal inter‐office interaction among frontline offices and illustrates how and under what conditions it shapes the meaning of law. Drawing on qualitative and quantitative data on Japan's Soil Contamination Countermeasures Act, this study reveals that inter‐office interaction occurs within fixed groups and comes to shape shared interpretations of law that regulators believe are legally valid. This implies that under legal ambiguity, inter‐office interactions develop institutionalized notions of appropriateness and reinforce the perception of legal consistency, which bolster the legitimacy of enforcement. Although peer office networks encourage convergence on the interpretation of law, because of their clustered structure, legal meanings develop differently across various groups. en-copyright= kn-copyright= en-aut-name=HirataAyako en-aut-sei=Hirata en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Faculty of Law, Okayama University kn-affil= en-keyword=environmental regulation kn-keyword=environmental regulation en-keyword=interpretation of law kn-keyword=interpretation of law en-keyword=networks among frontline offices kn-keyword=networks among frontline offices en-keyword=regulatory enforcement kn-keyword=regulatory enforcement en-keyword=street-level bureaucracy kn-keyword=street-level bureaucracy END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=4 article-no= start-page=1049 end-page=1054 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20090315 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Analysis of Factors Associated With Radiation-Induced Bronchiolitis Obliterans Organizing Pneumonia Syndrome After Breast-Conserving Therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: To evaluate factors associated with radiation-induced bronchiolitis obliterans organizing pneumonia (BOOP) syndrome after breast-conserving therapy.
Methods and materials: A total of 702 women with breast cancer who received radiotherapy after breast-conserving surgery at seven institutions between July 1995 and December 2006 were analyzed. In all patients, the whole breast was irradiated with two tangential photon beams. The criteria used for the diagnosis of radiation-induced BOOP syndrome were as follows: (1) radiotherapy to the breast within 12 months, (2) general and/or respiratory symptoms lasting for >or=2 weeks, (3) radiographs showing lung infiltration outside the radiation port, and (4) no evidence of a specific cause.
Results: Radiation-induced BOOP syndrome was seen in 16 patients (2.3%). Eleven patients (68.8%) were administered steroids. The duration of steroid administration ranged from 1 week to 3.7 years (median, 1.1 years). Multivariate analysis revealed that age (>or=50 years; odds ratio [OR] 8.88; 95% confidence interval [CI] 1.16-67.76; p = 0.04) and concurrent endocrine therapy (OR 3.05; 95% CI 1.09-8.54; p = 0.03) were significantly associated with BOOP syndrome. Of the 161 patients whose age was >or=50 years and who received concurrent endocrine therapy, 10 (6.2%) developed BOOP syndrome.
Conclusions: Age (>or=50 years) and concurrent endocrine therapy can promote the development of radiation-induced BOOP syndrome after breast-conserving therapy. Physicians should carefully follow patients who received breast-conserving therapy, especially those who are older than 50 years and received concurrent endocrine therapy during radiotherapy. en-copyright= kn-copyright= en-aut-name=KatayamaNorihisa en-aut-sei=Katayama en-aut-mei=Norihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoShuhei en-aut-sei=Sato en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatsuiKuniaki en-aut-sei=Katsui en-aut-mei=Kuniaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakemotoMitsuhiro en-aut-sei=Takemoto en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsudaToshihide en-aut-sei=Tsuda en-aut-mei=Toshihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshidaAtsushi en-aut-sei=Yoshida en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MoritoTsuneharu en-aut-sei=Morito en-aut-mei=Tsuneharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakagawaTomio en-aut-sei=Nakagawa en-aut-mei=Tomio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MizutaniAkifumi en-aut-sei=Mizutani en-aut-mei=Akifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=WakiTakahiro en-aut-sei=Waki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NiiyaHarutaka en-aut-sei=Niiya en-aut-mei=Harutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KanazawaSusumu en-aut-sei=Kanazawa en-aut-mei=Susumu 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 Radiology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Radiology, Okayama University 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 Radiology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Radiology, Okayama University Hospital kn-affil= en-keyword=Breast cancer kn-keyword=Breast cancer en-keyword=Breast-conserving surgery kn-keyword=Breast-conserving surgery en-keyword=Radiotherapy kn-keyword=Radiotherapy en-keyword=Radiation-induced BOOP syndrome kn-keyword=Radiation-induced BOOP syndrome en-keyword=Endocrine therapy kn-keyword=Endocrine therapy END start-ver=1.4 cd-journal=joma no-vol=43 cd-vols= no-issue=3 article-no= start-page=404 end-page=408 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200301 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Daily Meal Supplemented with Astaxanthin-Enriched Yolk Has Mitigative Effects against Hypertension in Spontaneously Hypertensive Rats en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study was to investigate the effects of egg yolk powder enriched with astaxanthin (ASX-E) on blood pressure in spontaneously hypertensive rats (SHR) and to verify the benefits of ASX-E as a functional food. To investigate the antihypertensive effect, SHR were fed with an ASX-E mixed diet before hypertension development. Blood pressures were determined periodically during the study by the tail-cuff method. At the end of the study, animals were euthanized, and their thoracic aortas were collected to determine vascular conductance. The thoracic aorta tension was measured with a force displacement transducer. Concentration-dependent response relationships were determined by cumulative addition of 10?9?10?4 M Carbamoylcholine (Cch). Blood pressures of the SHR in the ASX-E mixed diet group were ASX-dose-dependently lower than that of those in the control group. In SHR fed with an ASX-E mixed diet, Cch induced vasorelaxation in the thoracic aorta with endothelium lining but not without endothelium. However, the antihypertensive effect of ASX-E was not observed on blood pressures in SHR that were fed with ASX-E only after the development of hypertension. Results suggest that ASX-E protects endothelial function and thereby prevents the development of hypertension. Hence, the results of our research indicate that daily consumption of ASX-E has a potential benefit on human health. en-copyright= kn-copyright= en-aut-name=HatabuToshimitsu en-aut-sei=Hatabu en-aut-mei=Toshimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HaradaTakumi en-aut-sei=Harada en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakaoYuri en-aut-sei=Takao en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DungHo Thi en-aut-sei=Dung en-aut-mei=Ho Thi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamasatoAkihiro en-aut-sei=Yamasato en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HoriuchiTatsuya en-aut-sei=Horiuchi en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MochizukiAtsuya en-aut-sei=Mochizuki en-aut-mei=Atsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KondoYasuhiro en-aut-sei=Kondo en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental and Life Science , Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=K.I Chemical Industry Co., Ltd. kn-affil= affil-num=6 en-affil=K.I Chemical Industry Co., Ltd. kn-affil= affil-num=7 en-affil=K.I Chemical Industry Co., Ltd. kn-affil= affil-num=8 en-affil=Laboratory of Animal Physiology, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=astaxanthin-enriched egg yolk kn-keyword=astaxanthin-enriched egg yolk en-keyword=hypertension kn-keyword=hypertension en-keyword=spontaneously hypertensive rat kn-keyword=spontaneously hypertensive rat END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue= article-no= start-page=132 end-page=141 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Alkali Elution Behavior of Steelmaking Slag Packed in an Open Channel Vessel in Seawater en-subtitle= kn-subtitle= en-abstract= kn-abstract=The alkali elution behavior of steelmaking slag in seawater was kinetically investigated and simulated under continuous flow in an open channel vessel with packed bed of steelmaking slag. Two types of steelmaking slags, viz. decarburization slag and dephosphorization slag, were used in this study. The alkali elution rate of decarburization slag was larger than that of dephosphorization slag due to larger free CaO content. The pH value for dephosphorization slag was almost the same as the seawater pH value in 3?4 days, whereas that for decarburization slag was stabilized in 3 days although the pH value was slightly larger than that of seawater. The capacity coefficients of alkali elution for dephosphorization and decarburization slags decreased together in an exponential manner with time. Based on a regression equation on the mass transfer capacity coefficient change with time, the alkali elution behavior was simulated and the calculated results agreed well with the experimental ones. The temporal pH change was predicted by changing slag surface area and seawater flow rate as a parameter. According to the simulation results for dephosphorization slag, the seawater pH value did not reach a high level in the ocean area. en-copyright= kn-copyright= en-aut-name=MatsudaYamato en-aut-sei=Matsuda en-aut-mei=Yamato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UddinMd.

We previously investigated the mechanisms underlying dioecy in diploid persimmon (D. lotus) and found that male flowers are specified by repression of the autosomal gene MeGI by its paralog, the Y-encoded pseudo-gene OGI. This mechanism is thought to be lineage-specific, but its evolutionary path remains unknown. Here, we developed a full draft of the diploid persimmon genome (D. lotus), which revealed a lineage-specific whole-genome duplication event and provided information on the architecture of the Y chromosome. We also identified three paralogs, MeGI, OGI and newly identified Sister of MeGI (SiMeGI). Evolutionary analysis suggested that MeGI underwent adaptive evolution after the whole-genome duplication event. Transformation of tobacco plants with MeGI and SiMeGI revealed that MeGI specifically acquired a new function as a repressor of male organ development, while SiMeGI presumably maintained the original function. Later, a segmental duplication event spawned MeGI's regulator OGI on the Y-chromosome, completing the path leading to dioecy, and probably initiating the formation of the Y-chromosome. These findings exemplify how duplication events can provide flexible genetic material available to help respond to varying environments and provide interesting parallels for our understanding of the mechanisms underlying the transition into dieocy in plants. Author summary Plant sexuality has fascinated scientists for decades. Most plants can self-reproduce but not all. For example, a small subset of species have evolved a system called dioecy, with separate male and female individuals. Dioecy has evolved multiple times independently and, while we do not understand the molecular mechanisms underlying dioecy in many of these species yet, a picture is starting to emerge with recent progress in several dioecious species. Here, we focused on the evolutionary events leading to dioecy in persimmon. Our previous work had identified a pair of genes regulating sex in this species, called OGI and MeGI. We drafted the whole genome sequence of diploid persimmon to investigate their evolutionary history. We discovered a lineage-specific whole-genome duplication event, and observed that MeGI underwent adaptive evolution after this event. Transgenic analyses validated that MeGI newly acquired a male-suppressor function, while the other copy of this gene, SiMeGI, did not. The regulator of MeGI, OGI, resulted from a second smaller-scale segmental duplication event, finalizing the system. This study sheds light on the role of duplication as a mechanism that promote flexible genes functions, and how it can affect important biological functions, such as the establishment of a new sexual system. en-copyright= kn-copyright= en-aut-name=AkagiTakashi en-aut-sei=Akagi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShirasawaKenta en-aut-sei=Shirasawa en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NagasakiHideki en-aut-sei=Nagasaki en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HirakawaHideki en-aut-sei=Hirakawa en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TaoRyutaro en-aut-sei=Tao en-aut-mei=Ryutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ComaiLuca en-aut-sei=Comai en-aut-mei=Luca kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HenryIsabelle M. en-aut-sei=Henry en-aut-mei=Isabelle M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Kazusa DNA Research Institute kn-affil= affil-num=3 en-affil=Kazusa DNA Research Institute kn-affil= affil-num=4 en-affil=Kazusa DNA Research Institute kn-affil= affil-num=5 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=6 en-affil=Genome Center and Department of Plant Biology, University of California Davis kn-affil= affil-num=7 en-affil=Genome Center and Department of Plant Biology, University of California Davis kn-affil= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=24 article-no= start-page=5130 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191216 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Geographical Differences and the National Meeting Effect in Patients with Out-of-Hospital Cardiac Arrests: A JCS-ReSS Study Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=The "national meeting effect" refers to worse patient outcomes when medical professionals attend academic meetings and hospitals have reduced staffing. The aim of this study was to examine differences in outcomes of patients with out-of-hospital cardiac arrest (OHCA) admitted during, before, and after meeting days according to meeting location and considering regional variation of outcomes, which has not been investigated in previous studies. Using data from a nationwide, prospective, population-based, observational study in Japan, we analyzed adult OHCA patients who underwent resuscitation attempts between 2011 and 2015. Favorable one-month neurological outcomes were compared among patients admitted during the relevant annual meeting dates of three national scientific societies, those admitted on identical days the week before, and those one week after the meeting dates. We developed a multivariate logistic regression model after adjusting for confounding factors, including meeting location and regional variation (better vs. worse outcome areas), using the "during meeting days" group as the reference. A total of 40,849 patients were included in the study, with 14,490, 13,518, and 12,841 patients hospitalized during, before, and after meeting days, respectively. The rates of favorable neurological outcomes during, before, and after meeting days was 1.7, 1.6, and 1.8%, respectively. After adjusting for covariates, favorable neurological outcomes did not differ among the three groups (adjusted OR (95% CI) of the before and after meeting dates groups was 1.03 (0.83-1.28) and 1.01 (0.81-1.26), respectively. The "national meeting effect" did not exist in OHCA patients in Japan, even after comparing data during, before, and after meeting dates and considering meeting location and regional variation. en-copyright= kn-copyright= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaitouHiromichi en-aut-sei=Naitou en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=TaharaYoshio en-aut-sei=Tahara en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YonemotoNaohiro en-aut-sei=Yonemoto en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NonogiHiroshi en-aut-sei=Nonogi en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NagaoKen en-aut-sei=Nagao en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IkedaTakanori en-aut-sei=Ikeda en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SatoNaoki en-aut-sei=Sato en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TsutsuiHiroyuki en-aut-sei=Tsutsui en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, National Cerebral and Cardiovascular Center kn-affil= affil-num=5 en-affil=National Center of Neurology and Psychiatry kn-affil= affil-num=6 en-affil=Intensive Care Center, Shizuoka General Hospital kn-affil= affil-num=7 en-affil=Cardiovascular Center, Nihon University Hospital kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Toho University Faculty of Medicine kn-affil= affil-num=9 en-affil=Cardiovascular Medicine, Kawaguchi Cardiovascular and Respiratory Hospital kn-affil= affil-num=10 en-affil=Department of Cardiovascular Medicine, Kyushu University Faculty of Medical Sciences kn-affil= en-keyword=out-of-hospital cardiac arrest kn-keyword=out-of-hospital cardiac arrest en-keyword=outcome kn-keyword=outcome en-keyword=national meeting kn-keyword=national meeting en-keyword=cardiopulmonary resuscitation kn-keyword=cardiopulmonary resuscitation END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue= article-no= start-page=38 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190729 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-stay pediatric patients in Japanese intensive care units: their significant presence and a newly developed, simple predictive score en-subtitle= kn-subtitle= en-abstract= kn-abstract=BACKGROUND:
The length of stay (LOS) in intensive care units (ICUs) has been used as a good indicator not only for resource consumption but also for health outcomes of patients. However, data regarding pediatric LOS in Japanese ICUs are limited. The primary aim of this study was to characterize the Japanese pediatric ICU patients based on their LOS. Second, we aimed to develop a simple scoring system to predict long-stay pediatric ICU patients on admission.
METHODS:
We performed a retrospective cohort study using consecutive pediatric data (aged ?14?days) were identified using multiple regression analysis, and subsequently, a simple predictive scoring system was developed based on the results. The validity of the score was prospectively tested using data from the JaRPAC registration from October 2016 to September 2017.
RESULTS:
Overall, 4107 patients were included. Although LSPs were few (8.0% [n =?330]), they consumed 38.0% of ICU bed days (9750 for LSPs versus 25,659 overall). Mortality was seven times higher in LSPs than in short-stay patients (9.1% versus 1.3%). An 11-variable simple predictive scoring system was constructed, including Pediatric Index of Mortality 2???1 (2 points), liver dysfunction (non-post operation) (2 points), post-cardiopulmonary resuscitation (1 point), circulatory disorder (1 point), post-operative management of liver transplantation (1 point), encephalitis/encephalopathy (1 point), myocarditis/cardiomyopathy (1 point), congenital heart disease (non-post operation) (1 point), lung tissue disease (1 point), Pediatric Cerebral Performance Category scores ??2 (1 point), and age CONCLUSIONS:
Pediatric LSPs possess a significant presence in Japanese ICUs with high rates of bed utilization and mortality. The newly developed predictive scoring system may identify pediatric LSPs on admission. en-copyright= kn-copyright= en-aut-name=KnaupEmily en-aut-sei=Knaup en-aut-mei=Emily kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NosakaNobuyuki en-aut-sei=Nosaka en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NaitouHiromichi en-aut-sei=Naitou en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=the JaRPAC Study Group en-aut-sei=the JaRPAC Study Group en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Human Ecology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Pediatrics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil= kn-affil= en-keyword=Decision support kn-keyword=Decision support en-keyword=Intensive care kn-keyword=Intensive care en-keyword=Length of stay kn-keyword=Length of stay en-keyword=Mortality kn-keyword=Mortality en-keyword=Outcome kn-keyword=Outcome en-keyword=Pediatric kn-keyword=Pediatric en-keyword=Risk kn-keyword=Risk en-keyword=Prediction rules kn-keyword=Prediction rules en-keyword=Scoring system kn-keyword=Scoring system END
