昆虫の変態・休眠の分子機構

平成8年度から平成11年度までの4年間に実施された特定領域研究(A)(1)「昆虫の変態・休眠の分子機構(略称:変態・休眠機構)」は,昆虫の有する旺盛な生存,生活戦略を変態と休眠という高次の生命現象に焦点を合わせ,この分子機構を多面的に解明することを目的として,延べ62名の研究者の参加を得て進められ,多くの研究成果を挙げてきた.「変態・休眠を支配するホルモン分子の動態と環境応答」に関する研究では,脳神経ペプチドホルモンの遺伝子の同定,合成分泌とその調節機構,ホルモンの血中動態及びホルモン受容体の解析を進め,新たな知見を得た.また「変態における自己・非自己の認識転換と形作りの分子機構」に関する研究では,幼虫組織の識別と排除機構,成虫組織の分化発生機構,ミツバチの社会性分化をもたらす遺伝子の同定とその発現機構を解明した.これらの成果の一端は平成12年12月神戸市にいて開催された平成12年度文部省主催の「大学と科学」公開シンポジウム「昆虫から学ぶ生きる知恵」において,研究者のみならず一般市民約500名に対し,公表された.一方,総括班員を中心とした研究成果の最終まとめに関する検討をもとにして,学術審議会科学研究費分科会審査第一部会生物系小委員会による特定領域研究研究終了ヒアリングを受け,その結果,Aの評価を得た.また,本研究の成果は,研究目的や研究経過に加え,本研究参加者の研究結果と発表論文リストを編集した研究成果報告書として発刊し,関連機関や研究者等に配布した.科学研究費補助金 研究種目:特定領域研究(A)(1) 課題番号:08276103 研究代表者:山下 興亜 研究期間:1996-2000年度research repor

Analysis and consideration on results of long term mortar strength test

application/pdfIn this research， the strength of mortar specimens made during construction of Otaru　port were analyzed.　The experiment was planned and initiated by Dr.Isami HIROl in the　19th century.　The purpose of this study is to research the long-term strength and durability of mortar　specimens.　The results of these long-term experiments carried out with various internal　factors(type of cement， type of fine aggregate， type of volcanic ash, water cement ratio)and　external factors (age and exposure conditions such as in water, in air，and in sea water)are　analyzed.　　　　The long-term mortar strength test can be summarized as follows : ?tensile strength is　affected by water-binder ratio， water-cement ratio， cement proportion， and volcanic ash　proportion.　?the reliability of not declining the tensile strength of age 28 days was 52 ％，that of 3 months ； 5 ％，and that of 1 year ； nearly 0 ％ at the age 80 years.departmental bulletin pape

Dynamics of BrdU incorporation in pSC shaft and socket cells from 17.5 to 29 hours APF.

<p>Pupae with the +/+ genotype were grown until particular times of development and BrdU incorporation assays were performed as described in the <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0038714#s4" target="_blank">Materials and Methods</a>. Images show pSC shaft and socket cells stained with DAPI and anti-BrdU antibodies (A–H). Arrows indicate socket cell nuclei. Arrowheads indicate shaft cell nuclei. Note the BrdU incorporation observed in A, C, F, G in shaft cells and in C, D, H in socket cells. (I) Pattern of BrdU incorporation in shaft cells from 17.5 to 29 hours APF. The Y axis indicates the % of BrdU incorporation in shaft and socket cells. Sample numbers and detailed data are described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0038714#pone.0038714.s002" target="_blank">Table S1</a>.</p

Dynamics of nuclear growth in pSC shaft cells from 8 to 29 hours APF.

<p>(A–O) Images of pSC shaft cells from 8 to 29 hours APF. Pupae with the <i>A101-lacZ /+</i> genotype were grown till 8(n = 6), 12(n = 3), 18(n = 8), 20(n = 11), 21(n = 8), 22(n = 8), 23(n = 3), 24(n = 7), 25(n = 5), 26(n = 11), 27(n = 6), 29 hours APF (n = 7) and dissected thoraxes were stained with anti-lacZ and DAPI. Arrows indicate socket cell nuclei and arrowheads shaft cell nuclei. (P) Dynamics of nuclear growth in a pSC shaft cell from 8 to 29 hours APF. The Y axis indicates the section area of the shaft cell nucleus. Significant differences in mean values at each time point to those of adjacent time points were set at *P<0.05, **P<0.01 and ***P<0.001. (Q) Illustration of 22 macrochaetes on left and right sides of an adult thorax. pSC, posterior scutellar; aSC, anterior scutellar; pDC, posterior dorsocentral; aDC, anterior dorsocentral; pPA, posterior postalar; aPA, anterior postalar; pSA, posterior supraalar; aSA, anterior supraalar; pNP, posterior notopleural;, aNP, anterior notopleural; PC, presutural.</p
