Graphene (G) was dispersed into 0.5% chitosan (Chit) solution, then the composite films were coated on glassy carbon electrode (GCE), the electrochemical behavior of rutin on a Chit/G modified GCE was investigated and the electrochemical parameters of rutin were calculated.Rutin effectively accumulated on the Chit/G/GCE and caused a pair of redox peaks at around 408 mV and 482 mV (vs.SCE) in 0.1 M phosphate buffer solution (pH 4.0).Under optimized conditions, the anodic peak current was linear to the rutin concentration in the range of 5 × 10-7-1.04 × 10-5 M.The regression equation was: y=9.9219x-0.0025, r=0.9958.The proposed method was successfully used for the determination of rutin content in tablet samples with satisfactory results.

滋养层干细胞(TS)是胎盘组织细胞的祖细胞，与胚胎着床和胎盘的形成密切相关。胚胎着床和胎盘形成是母体与胎儿建立联系的关键时期，此时期滋养层细胞增殖速度快，滋养层干细胞自我更新和分化旺盛，与多种妊娠相关疾病的发生、发展及其增殖、功能调节的失常有密切关系。本研究利用人工受精猪囊胚分离培养得到猪TS细胞，在此基础上，以TS细胞为供体细胞，以杜洛克克隆胚胎为受体，通过piezo系统将TS细胞注射到囊胚腔内
猪卵母细胞内脂滴丰富,脂解生成的脂肪酸氧化产生大量的ATP,为卵母细胞体外成熟及胚胎发育提供能量。但是过多的脂滴严重影响了猪卵母细胞与早期胚胎的冷冻存活率。离心去脂虽然有效提高了冷冻效率,但脂滴去除后胚胎中剩余的脂滴和活性线粒体的含量都大幅度降低,两者的动态分布也受到影响。胚胎中能量代谢通路也发生变化。严重损害了胚胎发育成囊胚的能力。说明脂滴和线粒体的含量和分布与胚胎发育能力密切相关。本实验借助离

自1997年"Dolly"羊诞生以来，哺乳动物体细胞核移植(SCNT)技术发展迅速，但总体效率仍然很低，其中卵母细胞去核方法是提高克隆效率的研究热点之一。目前常用的去核方法主要包括盲吸法、化学去核法、纺锤体观测去核法以及染色去核法。染色去核法能达到完全去核的目的，但应用荧光染料和紫外光可能对母源胞质造成负面影响。本研究比较了猪卵母细胞的核染色和控制紫外光(UV)照射强度对孤雌激活(PA)胚和SCN
