Since myoelectric control is direct and natural, the prosthesis control by SEMGhas been the dominant sort in the exterior powered prosthesis.

由于肌电控制假肢具有直接、自然的特点，利用表面肌电控制的假肢已成为外部动力假肢中数量占绝对优势的一类。

Results Actin was only detected in myoepithelial cells of normal breast tissue and grade Ⅰ and Ⅱ atypical hyperplasia.

结果 正常乳腺组织和Ⅰ级一般性增生乳腺组织中肌动蛋白只在肌上皮细胞中表达。

The changes of actin expression in atypical hyperplasia are possibly correlated with carcinogenesis of breast cancer, and myoepithelial cells may play a role in carcinogenesis of breast cancer.

乳腺不典型增生时肌动蛋白表达的变化可能与乳腺癌的发生有关，肌上皮细胞可能参与了乳腺癌的发生。

Methods SP immunohistochemistry was used to detect actin expression in normal breast tissue, grade Ⅰ,Ⅱ and Ⅲ atypical hyperplasia and breast cancer. Electromicroscopy was used to observe the changes of ultrastructure of myoepithelial cells.

用免疫组化SP法分别检测正常乳腺组织、Ⅰ级一般性增生和Ⅱ级、Ⅲ级不典型增生乳腺组织及乳腺癌组织中肌动蛋白的表达情况，并用电镜观察肌上皮细胞超微结构的变化。

Results:There is a close positive correlation between myoepithelial cell differentiation and glandular cell maturation and the ratio of myoepithelial cells to glandular endpieces area was decreased.

结果：实验结果提示，小鼠泪腺肌上皮细胞从出现到成熟的形态变化，与腺细胞内的分泌颗粒从出现到增多是同期发育的，泪腺腺房与肌上皮细胞的面积比率呈减小趋势。

So, physiological hypoxia is actually optimum condition for myogenesis. There have been few studies on effects of hypoxia on proliferation and differentiation of myoblasts up to now.

而生理性的低氧条件才是成肌发生过程中的最适条件，目前关于低氧对成肌细胞增殖和分化的影响的研究报道甚少。

Despite of its important role during embryogenesis and reproductive development,more and more studies implied a critical role for Rhox5 on the determination and differentiation during myogenesis.

除在生殖系统的发育、精子的形成和成熟过程中发挥重要的作用外，多项研究表明其在肌细胞的发生和分化中担任重要角色，有可能作为MyoD基因的上游调控子或者和其他转录因子协同作用，调控肌细胞的早期发生和分化事件。

To generate recombinant adenovirus expression vector of human Sema4C gene and observe its expression in mouse myoblasts cell line C2C12 for ensuring easy access to investigate the role of Sema4C gene during myogenesis.

利用Ad5腺病毒载体系统构建人Sema4C基因重组腺病毒表达载体并在成肌细胞系C2C12中表达，并初步探讨Sema4C基因在成肌发育过程中的可能作用。

C2C12 cells were induced to differentiation into muscle cells in vitro and the myogenesis model was detected by inverted microscope, RT-PCR, western-blot, cell immunofluorescence histochemistry, flow cytometry and confirmed to be successful. On the foundation of differentiation model, miR-206 was detected by northern hybridization and the result showed that the expression level increasing gradually during muscle differentiation with a character of phase specificity.

利用C2C12细胞在体外成功诱导其向成肌细胞分化，通过形态学观察，RT-PCR、western-blot、细胞免疫荧光组织化学及流式细胞仪等方法进行检测，证实我们所建立的细胞分化模型是成功的，并观察到随着诱导时间的延长，miR-206在成肌分化过程中表达量逐渐增高的，表达改变具有阶段特异性。

Extracellular calcium is required for normal progression through the initial recognition-alignment phase of myogenesis. A net calcium influx into fusion-competent myoblasts is a requisite step in membrane fusion.

细胞与细胞之间识别和并列的初期阶段，胞外钙离子的内流是正常肌细胞生成过程所必不可少的，钙离子进入具有融合潜能的成肌细胞内，从而使细胞膜发生融合。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
