The results showed that the treatment with argon plasma removed carbon contaminants and increased the surface energy of the material while the nanoscale network structure deposited on the titanium surface remained in place. Reactive oxygen species reduced the oxidative stress of bone marrow cells on the treated titanium surface, creating a favorable environment for cell proliferation. Good results were observed in vitro evaluations using rat bone marrow cells. The group treated with argon plasma exhibited the highest apatite formation in experiments using simulated body fluids. The results of in vivo evaluation using rat femurs revealed that the treatment improved the amount of new bone formation around an implant. Thus, the results demonstrate that argon plasma treatment enhances the ability of nanostructured titanium surfaces to induce hard tissue differentiation and supports new bone formation around an implant site.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10006_dissertation_number_12":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第995号"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"作成者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"林, 莉菜","creatorNameLang":"ja"},{"creatorName":"ハヤシ, リナ","creatorNameLang":"ja-Kana"},{"creatorName":"Hayashi, Rina","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":"2024-06-01"}],"filename":"kou_995_ab.pdf","filesize":[{"value":"241 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"本文内容要旨・審査結果要旨","objectType":"abstract","url":"https://osaka-dent.repo.nii.ac.jp/record/2000107/files/kou_995_ab.pdf"},"version_id":"15fc823a-1e0e-4e7f-86e2-b7667dbcce2f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"argon plasma treatment/titania nanosheets","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"reactive oxygen species","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"hard tissue differentiation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"rat bone marrow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"bone formation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"simulated body fluid","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":"Effects of Argon Gas Plasma Treatment on Biocompatibility of Nanostructured Titanium","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effects of Argon Gas Plasma Treatment on Biocompatibility of Nanostructured Titanium","subitem_title_language":"en"},{"subitem_title":"ナノ構造処理した純チタン金属へのアルゴンガスプラズマ処理が生体適合性に与える影響","subitem_title_language":"ja"}]},"item_type_id":"10006","owner":"18","path":["65"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-01"},"publish_date":"2024-06-01","publish_status":"0","recid":"2000107","relation_version_is_last":true,"title":["Effects of Argon Gas Plasma Treatment on Biocompatibility of Nanostructured Titanium"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-06-07T06:52:18.143412+00:00"}
