核丝

For a historical example, Margulis suggests her own studies on the symbiotic nature of nucleated cells.

玛格丽丝建议把她本人关于有核细胞共生本性的研究作为生物史的一个例子。

The injured gill cells had a different ultrastructure, with endoplasmic reticulum dilated and vesiculated, mitochondrial cristaes partially disintegrated, gill fibre cuticles denatured and dropped. The ultrastructural damages to hepatopancreatic cells were characterized by the decrease of microvilli, swelling and breaking up of mitochondria, expansion of endoplasmic reticulum, disruption and vacuolization of nucleus, tumefaction of nuclear membrane and increase of lipid droplets. As for the toxicological changes of myocardial cells, the mitochondria were swelling, having a lot of vacuolus and disintegrating, while the myofibrils were irregular with endoplasmic reticulum dissolved.

鳃细胞的损害表现为鳃丝水肿，细胞器溶解，角质层变薄，线粒体、内质网的肿胀、解体；肝胰脏细胞的主要损害特征为肝管微绒毛减少，线粒体水肿解体，内质网扩张，细胞核空泡化，核膜水肿和脂肪滴增加；心脏细胞的毒理变化为线粒体内嵴肿胀、瓦解，肌原纤维不规则，内质网溶解。

沧州金丝小枣以其皮薄核小、肉厚而韧、含糖量高、掰开后可拉出金黄色糖丝的独特品质，享誉囤内外市场，是河北省主要的创汇农副产品之一。

The system of drive are all driven by stepping motors.the machine system design includes every free degrees,computation of drive and transmission system .the third and four degree of freedom are performed by the feed screw having the spline of ball bearing which is design specially for robot .with the textual study,it can be believe the user will have an overall understanding to the way of thinking and steps of the machine system.

在机械系统设计上，对每个自由度驱动、传动系统进行了计算与校核，其中第三四自由度有专为机器人设计的带滚珠花键的丝杠来实现。通过本文的学习，相信使用者会对它的机械系统设计的步骤和方法有一定的了解。

The nuclear phase and mitosis in germ tube of Fusarium graminearum were studied with staining by Giemsa techniques. There was single nucleus in conidial cell.

通过Giemsa染色观察禾谷镰孢菌Fusarium graminearum分生孢子萌发过程中的核相变化及有丝分裂过程。

The mitogen-activated protein kinases play an important role in a variety of biological processes.

丝裂原活化蛋白激酶信号转导途径是真核生物中普遍存在的信号转导机制之一，三级激酶级联反应是其通路的核心成份。

Meanwhile, the mechanical behaviors of principle parts such as the spindle, bearings and lead screw are discussed. Their rigidity and strength are calculated and examined here.

同时，还就主轴、轴承以及丝杠等重要零件的机械性能进行了探讨，并对这些零件的刚度和强度进行了校核。

Objective: To express recombinant human endostatin in yeast and study its mitogenic activity on 3T3 fibroblast cells.

摘 要 目的：利用酵母真核细胞表达系统表达出重组人内皮抑制素，并对其促成纤维细胞有丝分裂活性进行研究。

In addition, we studied the distribution of mitochondria in metaphase Ⅱ rabbit oocytes, zygotes and early embryos by two active mitochondria dyes and revealed the change of active mitochondria during early development of rabbit embryos. We also found that the distribution of microfilaments and microtubules have similar patterns to that of active mitochondria, which is an important basis for further development of animal cloning study using the recipient oocytes derived from rabbit.

此外，我们应用两种线粒体荧光染料研究了日本大耳白兔体内成熟卵母细胞、正常交配后收集的受精卵及早期体外发育胚胎的活性线粒体的位置变化，首次揭示了兔早期胚胎中活性线粒体的变化特征及其与微丝微管变化的相关性，为进一步开展以兔卵母细胞作为核移植受体的动物克隆研究打下了重要的基础。
