Additionally, we examined the effects of different cell lines and time limitations using data from two other works.\nMethods We used the framework of the Monte Carlo method to create 3200 virtual experimental data sets of activity concentrations (kBq/g) to get the statistical information. Time activity concentration curves were produced using the fitting method of a genetic algorithm. The basic method was that absorbed doses of 211At-MABG were calculated based on the medical internal radiation dose formalism with the conversion of the physical half-life time of 131I to that of 211At. We have further improved the basic method, that is a novel dose conversion method, RAP (RAtio of Pharmacokinetics), using percent injected dose/g.\nResults Virtual experiments showed that 211At-MABG and 131I-MIBG had similar properties of initial activity concentrations and biological components, but the basic method did not simulate the 211At-MABG dose. Simulated 211At-MABG doses from 131I-MIBG using the RAP method were in agreement with those from 211At-MABG, so that their boxes overlapped in the box plots. The RAP method showed applicability to the different cell lines, but it was difficult to predict long-term doses from short-term experimental data.\nConclusions The present RAP dose conversion method could estimate 211At-MABG absorbed doses from the pharmacokinetics of 131I-MIBG with some limitations. The RAP method would be applicable to a large number of subjects for targeted nuclide therapy.\n","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s12149-020-01548-6","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://link.springer.com/article/10.1007/s12149-020-01548-6","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0914-7187","subitem_source_identifier_type":"ISSN"}]},"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":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sakashita, Tetsuya"}],"nameIdentifiers":[{"nameIdentifier":"1010995","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Watanabe, Shigeki"}],"nameIdentifiers":[{"nameIdentifier":"1010996","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hirohumi, Hanaoka (Gunma Univ)"}],"nameIdentifiers":[{"nameIdentifier":"1010997","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oshima, Yasuhiro"}],"nameIdentifiers":[{"nameIdentifier":"1010998","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ikoma, Yoko"}],"nameIdentifiers":[{"nameIdentifier":"1010999","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Naoyuki, Ukon (Fukushima Med Univ)"}],"nameIdentifiers":[{"nameIdentifier":"1011000","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sasaki, Ichiro"}],"nameIdentifiers":[{"nameIdentifier":"1011001","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Higashi, Tatsuya"}],"nameIdentifiers":[{"nameIdentifier":"1011002","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tetsuya, Higuchi (Gunma Univ)"}],"nameIdentifiers":[{"nameIdentifier":"1011003","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshito, Tsushima (Gunma Univ)"}],"nameIdentifiers":[{"nameIdentifier":"1011004","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishioka, Noriko"}],"nameIdentifiers":[{"nameIdentifier":"1011005","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tetsuya, Sakashita","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011006","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shigeki, Watanabe","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011007","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yasuhiro, Oshima","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011008","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoko, Ikoma","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011009","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ichiro, Sasaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011010","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tatsuya, Higashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011011","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Noriko, Ishioka","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011012","nameIdentifierScheme":"WEKO"}]}]},"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":"Absorbed dose simulation of meta-211At-astato-benzylguanidine using pharmacokinetics of 131I-MIBG, and a novel dose conversion method, RAP","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Absorbed dose simulation of meta-211At-astato-benzylguanidine using pharmacokinetics of 131I-MIBG, and a novel dose conversion method, RAP"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-07-14"},"publish_date":"2020-07-14","publish_status":"0","recid":"81168","relation_version_is_last":true,"title":["Absorbed dose simulation of meta-211At-astato-benzylguanidine using pharmacokinetics of 131I-MIBG, and a novel dose conversion method, RAP"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:01:52.417981+00:00"}
