Straightforward evidences by X-ray photoelectron spectroscopy (XPS) confirmed that the MPC layer peeled off on the bearing surface of all shortterm liners in both main wear and nonwear zones. Analyses by Fourier-transform infrared spectroscopy with attenuated total reflection assessed the extent of surface oxidation and revealed the type of oxidative species. Electron spin resonance analyses, which compared retrievals and as-received samples, revealed the presence of different species of alkoxyl CO• radicals. This study suggests that MPC grafts on polyethylene do not offer any additional protection from oxidation and can delaminate prematurely after short-term in vivo exposure.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_7_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"本文/Department of Orthopedic Surgery, Graduate School of Medicine, Mie University, Tsu City, Mie, Japan","subitem_description_type":"Other"},{"subitem_description":"11p","subitem_description_type":"Other"}]},"item_7_dissertation_number_60":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲医学第2065号"}]},"item_7_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_7_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1002/jbm.b.34617","subitem_relation_type_select":"DOI"}}]},"item_7_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_7_text_63":{"attribute_name":"ノート","attribute_value_mlt":[{"subitem_text_value":"Journal of Biomedical Materials Research Part B Applied Biomaterials 2020; 108(7) :2857-2867に掲載"}]},"item_7_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Doctoral Dissertation / 博士論文"}]},"item_7_version_type_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hosoi, Takashi","creatorNameLang":"en"},{"creatorName":"ホソイ, タカシ","creatorNameLang":"ja-Kana"},{"creatorName":"細井, 敬","creatorNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-06-29"}],"displaytype":"detail","filename":"2020DM0340.pdf","filesize":[{"value":"6.5 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"2020DM0340","objectType":"fulltext","url":"https://mie-u.repo.nii.ac.jp/record/14076/files/2020DM0340.pdf"},"version_id":"cdfa2fb2-b4f6-4e57-a172-678f83b9d953"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"alkoxyl radical","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"oxidation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"phosphorylcholine","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"polyethylene","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"total hip arthroplasty","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"MPC-grafted highly cross-linked polyethylene liners retrieved from short-term total hip arthroplasty: Further evidences for the unsuitability of the MPC method","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"MPC-grafted highly cross-linked polyethylene liners retrieved from short-term total hip arthroplasty: Further evidences for the unsuitability of the MPC method","subitem_title_language":"en"}]},"item_type_id":"7","owner":"16","path":["1262"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-06-29"},"publish_date":"2021-06-29","publish_status":"0","recid":"14076","relation_version_is_last":true,"title":["MPC-grafted highly cross-linked polyethylene liners retrieved from short-term total hip arthroplasty: Further evidences for the unsuitability of the MPC method"],"weko_creator_id":"16","weko_shared_id":-1},"updated":"2023-10-25T04:19:31.797511+00:00"}
