The study included 20 cases of HXLPE with antioxidants among the second-generation HXLPEs that were retrieved from in vivo after total hip and knee arthroplasty. The researchers measured the maximum oxidation index and oxidative induction time. The findings revealed that the oxidative induction time was significantly correlated with the vitamin E index, resulting in higher oxidation resistance in antioxidant infused HXLPE compared to antioxidant blended HXLPE. However, the maximum oxidation index showed a significant correlation with the duration of in vivo time, indicating that oxidative degradation may occur even when antioxidants are doped.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_8_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2019年度～2022年度科学研究費補助金(若手研究)研究成果報告書","subitem_description_type":"Other"}]},"item_8_description_64":{"attribute_name":"科研費番号","attribute_value_mlt":[{"subitem_description":"19K18462","subitem_description_type":"Other"}]},"item_8_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_8_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_8_text_65":{"attribute_name":"item_8_text_65","attribute_value_mlt":[{"subitem_text_value":"Kaken / 科研費報告書"}]},"item_8_version_type_15":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"刀根, 慎恵","creatorNameLang":"ja"},{"creatorName":"Tone, Shine","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-10-24"}],"filename":"2024RP0079.pdf","filesize":[{"value":"88 KB"}],"format":"application/pdf","url":{"label":"2024RP0079.pdf","url":"https://mie-u.repo.nii.ac.jp/record/2000989/files/2024RP0079.pdf"},"version_id":"8629ef6e-a72e-4f5c-b74d-7a3d9d4ea6a7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"人工関節置換術","subitem_subject_scheme":"Other"},{"subitem_subject":"ポリエチレン","subitem_subject_scheme":"Other"},{"subitem_subject":"インサート","subitem_subject_scheme":"Other"},{"subitem_subject":"ライナー","subitem_subject_scheme":"Other"},{"subitem_subject":"酸化度","subitem_subject_scheme":"Other"},{"subitem_subject":"酸化誘導時間","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"生体内より摘出された抗酸化剤添加ポリエチレンの物質構造の変化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"生体内より摘出された抗酸化剤添加ポリエチレンの物質構造の変化","subitem_title_language":"ja"},{"subitem_title":"Changing in material structure of anti-oxidant doped highly cross-linked polyethylene retrieved from in vivo","subitem_title_language":"en"}]},"item_type_id":"8","owner":"15","path":["1728958087061"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-10-24"},"publish_date":"2024-10-24","publish_status":"0","recid":"2000989","relation_version_is_last":true,"title":["生体内より摘出された抗酸化剤添加ポリエチレンの物質構造の変化"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2024-10-24T02:54:57.008190+00:00"}
