The hydration proceeds in the presence of 0.5 mol% of the ruthenium catalyst at 80 degrees C in 1,2-dimethoxyethane solution and the corresponding amide is obtained within few hours without the formation of by products. Comparison of some phosphine ligands for the hydration reveals that the dimethylamino moiety of 2 improves the catalytic performance dramatically. en-copyright= kn-copyright= en-aut-name=MuranakaMakoto en-aut-sei=Muranaka en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HyodoIsao en-aut-sei=Hyodo en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkumuraWataru en-aut-sei=Okumura en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OshikiToshiyuki en-aut-sei=Oshiki en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University affil-num=3 en-affil= kn-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University affil-num=4 en-affil= kn-affil=Division of Chemistry and Biochemistry, Graduate School of Natural Science and Technology, Okayama University en-keyword=Hydration kn-keyword=Hydration en-keyword=Nitrile kn-keyword=Nitrile en-keyword=Amides kn-keyword=Amides en-keyword=Homogeneous catalysis kn-keyword=Homogeneous catalysis en-keyword=Ruthenium kn-keyword=Ruthenium en-keyword=Phosphine kn-keyword=Phosphine END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=4 article-no= start-page=327 end-page=334 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=Cytotoxic Effects of Alcohol Extracts from a Plastic Wrap (Polyvinylidene Chloride) on Human Cultured Liver Cells and Mouse Primary Cultured Liver Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=An increasing accumulation of microplastics and further degraded nanoplastics in our environment is suspected to have harmful effects on humans and animals. To clarify this problem, we tested the cytotoxicity of two types of plastic wrap on human cultured liver cells and mouse primary cultured liver cells. Alcohol extracts from plastic wrap, i.e., polyvinylidene chloride (PVDC), showed cytotoxic effects on the cells. Alcohol extracts of polyethylene (PE) wrap were not toxic. The commercially available PVDC wrap consists of vinylidene chloride, epoxidized soybean oil, epoxidized linseed oil as a stiffener and stabilizer; we sought to identify which component(s) are toxic. The epoxidized soybean oil and epoxidized linseed oil exerted strong cytotoxicity, but the plastic raw material itself, vinylidene chloride, did not. Our findings indicate that plastic wraps should be used with caution in order to prevent health risks. en-copyright= kn-copyright= en-aut-name=YamamotoKen-ichi en-aut-sei=Yamamoto en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KagawaHiroko en-aut-sei=Kagawa en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ArimotoSakae en-aut-sei=Arimoto en-aut-mei=Sakae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanXian Wen en-aut-sei=Tan en-aut-mei=Xian Wen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YasuiKento en-aut-sei=Yasui en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OshikiToshiyuki en-aut-sei=Oshiki en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakaguchiMasakiyo en-aut-sei=Sakaguchi en-aut-mei=Masakiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Okayama University Hospital kn-affil= affil-num=3 en-affil=Division of Pharmaceutical Sciences, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cell Chemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=plastic wrap kn-keyword=plastic wrap en-keyword=plasticizer, kn-keyword=plasticizer, en-keyword=cytotoxicity, kn-keyword=cytotoxicity, en-keyword=liver cells kn-keyword=liver cells en-keyword=in vitro kn-keyword=in vitro 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= dt-pub= dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=有機エレクトロニクス材料の中規模製造工程の開発 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=押木俊之 kn-aut-sei=押木 kn-aut-mei=俊之 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 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= dt-pub= dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=高濃度ギ酸から水素を製造する化学触媒法 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OshikiToshiyuki en-aut-sei=Oshiki en-aut-mei=Toshiyuki kn-aut-name=押木俊之 kn-aut-sei=押木 kn-aut-mei=俊之 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 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= dt-pub= dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Toward Industrial Applications of Homogeneous Catalysts en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OshikiToshiyuki en-aut-sei=Oshiki en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=Okayama University, Collaborative Research Center 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= dt-pub= dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=地域の産学連携による省エネ型次世代触媒技術の開発 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=押木俊之 kn-aut-sei=押木 kn-aut-mei=俊之 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院自然科学研究科(工学系) END
