细胞分裂

The scientists hae repeatedly moed each cell's offspring to less crowded laboratory dished, allowing them to diide again and again.

科学家们不断地将每个细胞的后代转移到细胞密度比较小的培养皿，让它们可以不断地分裂增殖。

The results showed that pendimethalin is a herbicide interfering cell division,The mito-sis of pendimethalin treated root was arrested at metaphase with contracted and condensed chromo-somes and produced a series of abnormal,polymorphic cells such as multinucleate,multinucleolus,micronucleus and polyploid cells.

结果表明，除草通是一种影响细胞有丝分裂的除草剂，其作用方式在于阻止分生组织细胞从前期向中、后、末期的过渡，引起染色体凝集、短缩以及多核、多核仁等一系列畸形与异常变化。

When the cells were exposed to 10 nmol/L taxol for 24 h,significant cell-cycle arrest was also observed by fluorescence microscope,coexisting multinucleated cells were found as well.

随着作用时间延长，〓期阻滞增强，凋亡细胞百分率也随之增高，凋亡的出现滞后于有丝分裂阻滞，其峰值亦滞后于细胞周期阻滞的峰值。

All the movement in lives including muscule contraction,transportation inside the cells, duplication of genetic materials and even the cells'splitcan be traced to molecular motors.

生命体内的一切活动，从肌肉收缩、细胞内部的运输、遗传物质的复制，一直到细胞的分裂等等，都是源于具有分子功能的分子电机。

Its biological characteristic express two ways: increase wall of micrangium"s permeability and conjugate vascular endothelial cell"s specificreceptor, anxo-act vascular endothelial cell cleavage and proliferation, so lead to formate neogenetic vascular.

VEGF的生物学特性主要表现在两方面：增加微血管的通透性和特异性的与血管内皮细胞受体结合，促进血管内皮细胞的分裂和增殖，进而导致新生血管的生成。

Results There was significant negative correlation between the Nogo-A expression and the morphological change of tumor tissues according to immunohistochemistry. Western-blot analysis also indicated that the gray value of Nogo-A protein band in the oligodendroglioma group was significantly higher than that in the anaplastic oligodendroglioma group.

结果 免疫组织化学结果显示，Nogo-A免疫阳性染色的光密度值与肿瘤细胞核分裂、核异型比例呈明显的负相关，对蛋白印迹试验结果进行光密度分析也发现少突胶质细胞瘤中的Nogo-A蛋白条带灰度值明显高于间变型少突胶质细胞瘤中的灰度值。

Confocal laser scanning microscopy used to localize the hsp70 protein in oocytes and embryos revealed that the distribution of hsp70 in the ooplasm of immature and mature oocytes is unaffected by exposure to decreased or elevated temperatures and that this protein was closely associated with the meiotic spindle indicating its possible role in stabilizing this structure, hi eight-cell embryos derived under control conditions, hsp70 was evenly distributed in the cytoplasm but appeared as aggregates in some embryos exposed to elevated temperature.

此蛋白均匀地分布在两种细胞的胞浆中。此形态特点与减数分裂期纺缍体有关，由此表明hsp70在中期Ⅱ期，具有稳定这种结构的作用。在对照组8细胞胚中，hsp70均匀地分布在胞浆中，而在处理组一些胚胎内，hsp70则发生凝集。

A23187 and OA could parthenogenetically activate Urechis unicinctus oocytes and activate MAPK, indicating that the effect of fertilization on GVBD and activation of MAPK was mediated by rising in intracellular free calcium, and phosphorylation of some proteins was enough to activate the oocytes.

钙离子载体A23187和OA可以孤雌活化单环刺螠卵母细胞并激活MAPK。说明：①受精是通过钙离子的内流来激活卵母细胞并使MAPK活化的。②某些蛋白质的磷酸化状态对减数分裂是必要而且在一定程度上是充分的。

One has to search and count mitotic figures carefully in better preserved areas, and look for the other atypical features - hypercellularity, small cells with high nucleocytoplasmic ratios, patternless growth, and brain parenchymal invasion.

应该在保存好的区域仔细寻找计数核分裂，寻找其它非典型特征：细胞密集、核浆比高的小细胞、无序生长方式、脑实质浸润。

Periclinal Describing a line of cell division parallel to the surface of the organ. resuiting in the formation of periclinal walls between daughter cells and an increase in girth of the organ.

平周的：指一行细胞平行于器官表面进行分裂，导致子细胞间平周壁的形成以及器官厚度（原文为girth有误，译者注）的增加。

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。
