Heaney says that he suspects that vitamin C is good for the cells of normal tissue because it provides more protection for the mitochondria, and thus probably extends cell life.

希尼说，他怀疑，维生素C是良好的细胞的正常组织，因为它提供更多的保护线粒体，从而可能延长细胞寿命。

It is much more cellular and the cells have much more pleomorphism and hyperchromatism than the benign leiomyoma .

它比良性的平滑肌瘤的细胞成分多，且细胞的异型性更明显。

Possible cell sources for replacement range from autologous grafts of dopamine secreting cells to allografts of fetal ventral mesencephalon and neural precursor cells derived from fetal tissue or embryonic stem cells.

从多巴胺分泌细胞的自体移植物到胎儿组织的同种异体移植物或胚胎干细胞都是可替代的可能细胞来源。

In addition, studies have shown that the cytokine TGF-β produced by Tregs potently suppresses immune responses.

另外引起我们注意的是细胞激素—TGF-β。TGF-β是一个多功用的分子，特别是一种抑制免疫反应的细胞激素。

Spermatogenesis was disturbed by high-energy shock wave,in which the formation and differentiation of primary spermatocyte were inhibited.

高能冲击波对生精过程的作用可能是抑制初级精母细胞的形成和分化；多次高能冲击波冲击有诱导睾丸细胞凋亡数量增加的趋势。

Tight junctions are essential intercellular junctions, because their barrier and fence functions are indispensable for the establishment of compositionally distinct compartments in multicellular organisms.

紧密连接是上皮细胞间一个重要的连接构造，其功能对建立多细胞生物的隔室扮演不可或缺的角色。

Young thalluscells of low development are easy to dedifferentiate and grow intoseedings directly,while mature thallus cells have to releasemonospores to form seedings through a stage of multicellular groupfor dedifferentiation.Old thallus,mainly of productive cells,releasecarporspores to form conchocelis at last.

幼嫩的叶状体细胞，由于其分化程度低，易于脱分化而直接长成细胞苗；成熟的叶状体细胞，要经过多细胞团这样一个脱分化的阶段，然后放散单孢子成苗；而老叶状体以生殖细胞为主，只能放散果孢子，最终长成丝状体。

Prokaryotes are relatively simple, eukaryotes are more complex in structure and function

原核细胞的结构和功能都及其简单，而真核细胞就复杂的多

Using linear accelerator,the dose rate of the 6MV X-ray was 2Gy/min.The A549 spheroids was not more sensitive to low doses of single radiation.After exposure to 2-8Gy radiation,the spheroids recured quickly.Thetreatment of fractional radiation were more effective than single ones.With the increase of radiation doses,the 〓-M% block increased,numberof dead and apoptosis cells increased.

直线加速器产生的6MV高能X射线，2Gy／min的剂量率照射，A549多细胞球体对低剂量单次放疗不太敏感，2-8Gy范围内低剂量放疗后球体细胞很快增殖复发，分割放疗疗效优于单次放疗。

They exposed the cells to increasing amounts of paraquat or hydrogen peroxide, chemicals that cause oxidative stress and cell damage.

他们揭露了细胞越来越多的百草枯或过氧化氢，化学品引起氧化应激和细胞的损伤。

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。
