Apoptosis is a kind of cell death in human and other multicellular organism, it is neither always abnormal nor always detrimental, and the homeostatic balance of the number of cells is determined by both proliferation and apoptosis of cells.

细胞凋亡是存在于人类和多细胞生物中的一种主动的死亡方式，它通常并不是异常的和有害的，它与细胞增生共同维持着组织中细胞数量的动态恒定状态。

Prolonged overstimulation of dopamine receptors caused by methamphetamine may eventually cause the receptors to downregulate in order to compensate for increased levels of dopamine within the synaptic cleft.

甲基苯丙胺所引起的对多巴胺接受细胞的持续刺激可能最终会这些接受细胞变少，从而能应对神经键隙中大量的多巴胺。

Institute of Botany, the Chinese Academy of Sciences, Beijing 100093Abstract Plasmodesma is a supracellular structure of plant organism. It provides a direct cell-to-cell cytoplasmic pathway for material transport and message transference, and converts the colonies of independent cells into an interconnected symplast system.

胞间连丝为多细胞植物有机体提供了一个直接的细胞间物质运输和信息传递的细胞质通道，把一个个独立的"细胞王国"转变成相互连接的共质体，它是当今细胞生物学中十分活跃的研究领域。

These protists live as individual amoebae until starved, at which point they aggregate and form a multicellular fruiting body in which some cells sacrifice themselves to promote the survival of other cells in the fruiting body.

这些protists生活作为个人阿米巴直至饿死，而此时他们合计，形成一个多细胞子实体，其中一些细胞牺牲自己，以促进生存的其他细胞的子实体。

Results: T cell anergy was antigen-specific. The state of T cell anergy can be reversed by PHA, CD3 mAb and PMA plus A23187. IL-2 can prevent the induction of T cell anergy, but it can not reverse the state of un-responsiveness. IL-2 and IFN mRNA can not express in anergic T cells. In contrast, IL-4 and IL-10 mRNA were detectable.

结果：T细胞无能为抗原特异性的，多克隆激活剂PHA、CD3单抗和PMA+A23187可以恢复无能T细胞的活性；IL-2可以阻止T细胞无能的形成，但不能逆转其耐受状态；无能T细胞IL2和IFN mRNA是关闭的，而IL-4和IL-10 mRNA则是开放的。

Carotene and bixin inhibited the of MCF-7 human breast cancer cell significantly. The effects of carotenoids were pleiotropic.β-Carotene can activate PPARγ signal pathway and regulate expression of the downstream and relative genes, and impel cytochrome C liberation from mitochndria and increase the level of reactive oxygen species in cell.

胡萝卜素与胭脂树橙显著抑制乳腺癌MCF-7细胞的生长，β-胡萝卜素的抑制作用可能是多效性的，一是激活PPARγ信号系统，调节PPARγ下游基因及相关基因表达，另一个是促使线粒体中的细胞色素C释放，引起细胞内活性氧生成增加，导致细胞活力下降或坏死。

The C3A spheroids displayed multilayer cell morphology, characterized by a large number of tight junctions, polar cells, and bile canaliculi, similar to spheroids of primary hepatocytes.

这个C3A球形体显示出多层细胞的形态学特征，包括有大量的紧密连接、极性细胞及胆小管，这与原代肝细胞球形体相似。

The pinwheel's core contains the apical endings of B1 cells and in its periphery two types of ependymal cells: multiciliated (E1) and a type (E2) characterized by only two cilia and extraordinarily complex basal bodies.

其中风车的中心含有B1细胞的顶端末梢，而在风车周围则包含两种室管膜细胞：其中一种是多纤毛的E1细胞，另一种则是具有2纤毛以及非常复杂基体的E2细胞。

其车的中心含有B1细胞的顶端末梢，而在风车周围则包含两种室管膜细胞：其中一种是多纤毛的E1细胞，另一种则是具有2纤毛以及非常复杂基体的E2细胞。

Most of the prior NSC studies used cells expanded using neurosphere generation, in which nonadherent cells proliferate to form multicell spheres.

大多数以前的NSC研究使用神经干细胞球进行细胞的扩增，其中非粘附细胞扩增形成多细胞球。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
