However, the precise localization of uranium within the bone is not well known. In this study, we analyzed the distribution of uranium in the femur of rats exposed to uranium. For our analysis, we used synchrotron radiation X-ray fluorescence analysis with high-energy excitation X-rays with microbeam (high-energy SR-μXRF). To quantify uranium in bone tissues, we modified our previously developed thin section standards. Additionally, we prepared droplet standards for quantifying bone calcium. Our findings showed that uranium concentration at bone sites was estimated to be 20% lower than at bone marrow sites of the same intensity, likely owing to matrix effects. The elemental mapping of the femur's frozen section specimens showed that uranium was distributed in a very limited surface layer bordering the bone marrow, one day post-administration.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"ELSEVIER"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.microc.2024.112278","subitem_relation_type_select":"DOI"}}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kato Yugo"}]},{"creatorNames":[{"creatorName":"Yakumaru Haruko"}]},{"creatorNames":[{"creatorName":"Ayama Kyoko"}]},{"creatorNames":[{"creatorName":"Terauchi Miyu"}]},{"creatorNames":[{"creatorName":"Numako Chiya"}]},{"creatorNames":[{"creatorName":"Sekizawa Oki"}]},{"creatorNames":[{"creatorName":"Nitta Kiyofumi"}]},{"creatorNames":[{"creatorName":"Takeda Shino"}]}]},"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":"Uranium micro localization in the femur of rats exposed to uranium acetate","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Uranium micro localization in the femur of rats exposed to uranium acetate","subitem_title_language":"en"}]},"item_type_id":"8","owner":"9","path":["1"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-12-04"},"publish_date":"2024-12-04","publish_status":"0","recid":"2001233","relation_version_is_last":true,"title":["Uranium micro localization in the femur of rats exposed to uranium acetate"],"weko_creator_id":"9","weko_shared_id":-1},"updated":"2025-10-16T05:46:10.330609+00:00"}
