Experiments using axenic culture medium have demonstrated that the hypergravity affected directly on the proliferation of Paramecium itself (Kato et al., 2003). An attempt to elucidate the mechanisms underlying the gravity-dependent changes in proliferation in terms of the cellular energetics in relation to the motile activities has been made. Paramecium would be assumed to decrease the energy expenditure for motility under microgravity and increase it under hypergravity because of the characteristics of 'gravitaxis' and 'gravikinesis'. The larger stock of energy would enhance the proliferation activity under microgravity and smaller stock would reduce the activity under hypergravity. In order to assess the feasibility of the assumption above, Paramecium tetraurelia was grown under simulated weightlessness performed by clinorotation. Under clinorotation with the rotation rate of 2.5 rpm, Paramecium proliferated to 51 percent lower saturation density than that under control normal gravity. This reduced proliferation activity was found under the clinorotation with higher rate (4.8 rpm) but appeared less pronounced with lower rotation rate (0.2 rpm).","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0048095043","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"お茶の水女子大学 大学院人間文化研究科"},{"subitem_text_value":"お茶の水女子大学 理学部　生物学科"},{"subitem_text_value":"お茶の水女子大学 大学院人間文化研究科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Ochanomizu University Graduate School of Humanities and Sciences"},{"subitem_text_language":"en","subitem_text_value":"Ochanomizu University Department of Biology, Faculty of Science"},{"subitem_text_language":"en","subitem_text_value":"Ochanomizu University Graduate School of Humanities and Sciences"}]},"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":"澤井, 里枝"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"最上, 善広"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"馬場, 昭次"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sawai, Satoe","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mogami, Yoshihiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Baba, Shoji A.","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ゾウリムシ","subitem_subject_scheme":"Other"},{"subitem_subject":"増殖","subitem_subject_scheme":"Other"},{"subitem_subject":"傾斜回転","subitem_subject_scheme":"Other"},{"subitem_subject":"培養細胞","subitem_subject_scheme":"Other"},{"subitem_subject":"カーブフィッティング","subitem_subject_scheme":"Other"},{"subitem_subject":"最小2乗法","subitem_subject_scheme":"Other"},{"subitem_subject":"重力","subitem_subject_scheme":"Other"},{"subitem_subject":"ロジスティック成長式","subitem_subject_scheme":"Other"},{"subitem_subject":"時間経過","subitem_subject_scheme":"Other"},{"subitem_subject":"重力効果","subitem_subject_scheme":"Other"},{"subitem_subject":"paramecium","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"proliferation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"clinorotation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cultured cell","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"curve fitting","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"least square method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gravitation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"logistic growth equation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"time course","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gravitational effect","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Effect of clinorotation on the proliferation of Paramecium tetraurelia","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effect of clinorotation on the proliferation of Paramecium tetraurelia","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1646","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"13772","relation_version_is_last":true,"title":["Effect of clinorotation on the proliferation of Paramecium tetraurelia"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T05:45:02.326662+00:00"}
