Analysis of lipid and fatty acid composition during embryonic and larval development of Oratosquilla kempi(黑斑口虾蛄胚胎和幼体不同发育时期脂类及脂肪酸组成分析)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2007
通过生物化学成分测定,分析黑斑口虾蛄(Oratosquilla kempi)胚胎和幼体不同发育时期的水分、总脂和脂肪酸的组成及体积分数、质量分数变化.结果显示,黑斑口虾蛄在胚胎和幼体的发育过程中,水的体积分数先降低,至原肠胚期开始升高,到第二相幼体期达到最高,之后又有所回落;脂类占组织干重的比率呈升高趋势,但分别在膜内无节幼体、第二相幼体和仔虾蛄期略有降低;脂类占组织湿重的比率呈降低趋势;花生四烯酸、EPA和DHA的体积分数都呈降低趋势 ...

Gut microbiota dynamics of adult and sub‐adult sika deer during reintroduction 重引入过程中成年和亚成年梅花鹿肠道微生物的动态变化

open access: yesIntegrative Conservation, Volume 3, Issue 3, Page 257-270, September 2024.
Natural training enclosure design schematic. We selected 12 sika deer including six adults and six sub‐adults. Key considerations in the design of the natural training were to divide the training spatial ground into two parts (30 × 30 m small areas for isolation of new individuals and large areas measuring 200 × 600 m for free walking), and the ...

兔脂肪间充质干细胞向胰岛素样分泌细胞分化及鉴定

open access: yesZhongguo shiyan zhenduanxue, 2014
脂肪间充质干细胞(adipose-derived mesenchymal stem cells,ADSCs)最早由Zuk[1]等人于2001年从抽脂术中抽取的脂肪组织中分离培养,近年来已成为医学领域乃至整个生命科学领域的研究热点。ADSCs是一种来源于脂肪组织中的多能干细胞,和骨髓间充质干细胞(bone marrow mesenchymal stem cells,BMSCs)类似,也有很强的增殖能力和分化潜能。ADSCs能在不同的诱导微环境下向不同的组织细胞(如脂肪细胞、成骨细胞、内皮细胞、
