Hydroxyl radical (•OH), hydrogen peroxide (H2O2), and the total amount of oxidation reactions, which occurred mainly because of •OH and/or hydroperoxy radicals (HO2•), were measured by electron paramagnetic resonance-based methods. •OH generation was expected to be localized on the track/range of the carbon-ion beam/X-ray, and mM and M levels of •OH generation were observed. Total •OH generation levels were identical at the same dose irrespective of whether X-ray or carbon-ion beam irradiation was used, and were around 0.28‒0.35 μmol/l/Gy. However, sparse •OH generation levels decreased with increasing linear energy transfer, and were 0.17, 0.15, and 0.09 μmol/l/Gy for X-ray, 20 keV/μm carbon-ion beam, and >100 keV/μm carbon-ion beam sources, respectively. H2O2 generation was estimated as 0.26, 0.20, and 0.17 μmol/l/Gy, for X-ray, 20 keV/μm carbon-ion beam, and >100 keV/μm carbon-ion beam sources, respectively, whereas the ratios of H2O2 generation per oxygen consumption were 0.63, 0.51, and 3.40, respectively. The amounts of total oxidation reactions were 2.74, 1.17, and 0.66 μmol/l/Gy, respectively. The generation of reactive oxygen species was not uniform at the molecular level.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.3164/jcbn.18-34","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.jstage.jst.go.jp/article/jcbn/advpub/0/advpub_18-34/_article","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0912-0009","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ken-ichiro, Matsumoto"}],"nameIdentifiers":[{"nameIdentifier":"773971","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nyui, Minako"}],"nameIdentifiers":[{"nameIdentifier":"773972","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ueno, Megumi"}],"nameIdentifiers":[{"nameIdentifier":"773973","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ogawa, Yukihiro"}],"nameIdentifiers":[{"nameIdentifier":"773974","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakanishi, Ikuo"}],"nameIdentifiers":[{"nameIdentifier":"773975","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsumoto, Kenichiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"773976","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nyui, Minako","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"773977","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ueno, Megumi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"773978","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ogawa, Yukihiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"773979","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakanishi, Ikuo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"773980","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-08-06"}],"displaytype":"detail","filename":"c4cf8979655f74596baab8ae4a6a061f.pdf","filesize":[{"value":"552.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Matsumoto.K.2019.J.Clin.Biochem.Nutr.65.1-7.pdf","url":"https://repo.qst.go.jp/record/49452/files/c4cf8979655f74596baab8ae4a6a061f.pdf"},"version_id":"4e21169b-f34d-464c-96fa-76a03f2f5f0f"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"A Quantitative Analysis of Carbon-Ion Beam-Induced Reactive Oxygen Species and RedOx Reactions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A Quantitative Analysis of Carbon-Ion Beam-Induced Reactive Oxygen Species and RedOx Reactions"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-12-14"},"publish_date":"2017-12-14","publish_status":"0","recid":"49452","relation_version_is_last":true,"title":["A Quantitative Analysis of Carbon-Ion Beam-Induced Reactive Oxygen Species and RedOx Reactions"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:24:30.654425+00:00"}
