两细胞的

Although marmoset bip is high homologous to human slam, they have some important differences.

最终证实：绒猴B-类淋巴母细胞表面存在的BIP蛋白具有与人的SLAM蛋白相同的功能，它是B95a型病毒感染B95a细胞的受体分子，虽然这两个基因具有高度的同源性（91％），但仍具有许多重要的差异。

We hypothesized that Notch signaling might play an important role in specifying endothelial progenitors from the mesoderm, given that this pathway acts as a bipotential cell-fate switch on equipotent progenitor populations in other settings.

由于在其他系统中的研究表明，Notch信号通路在同一潜能的前体细胞走向两种不同命运的过程中发挥着关键的转换作用，我们假定该通路在中胚层特化为内皮前体细胞的过程中也发挥重要功能。

An organism or cell having two sets of chromosomes or twice the haploid number.

有两套染色体或者是单倍体两倍的数目染色体的细胞或有机体。

Experiments of photosensitization exhibited that, when irradiated with red light, the photodamaging effects on cells of both photosensitizers are close to each other; but when exposed to room light the cytotoxic effect of AISPC is lower than that of HPD, suggesting a potential advantage of reducing undesired side effects in clinical application.

光敏杀伤的结果表明，在红光照射下，两光敏剂对细胞有相近的杀伤效率；在室内自然光下，AISPC对细胞的损伤明显低于HPD，显示出其较低的光毒付作用，具有适合临床应用的优点。

Two polar nuclei move to the micropylar end before sperm is released in a gap between the egg cell and central cell and subsequently taking off cytoplasm one after another. The sperm nucleus moving to the egg nucleus runs faster than the one to the polar nuclei. It fuses with the polar nuclei that are moving towards the antipodal cells at the chalazal end.

精子释放前，两极核移向卵细胞的合点端；两精子释放于卵细胞与中央细胞的间隙后，先后脱去细胞质，然后分别移向卵核和极核，移向卵核的精核快于移向极核的精核；精核与两极核在向反足细胞团方向移动的过程中完成雌雄核融合。

The sperm nucleus moving to the egg nucleus runs faster than the one to the polar nuclei. It fuses with the polar nuclei that are moving towards the antipodal cells at the chalazal end, Images showed the fusion process of male and female nuclei and polyspermous fertilization.

精子释放前，两极核移向卵细胞的合点端；两精子释放于卵细胞与中央细胞的间隙后，先后脱去细胞质，然后分别移向卵核和极核，移向卵核的精核快于移向极核的精核；精核与两极核在向反足细胞团方向移动的过程中完成雌雄核融合。

It was noticed that Majority (13/25) of C DRG cells and minority of A DRG cells were depolarized by bath application of morphine at the dose of 0.1mmol/L.

在新生大鼠脊髓—背根神经节标本上细胞内记录背根神经节两类细胞的膜电位，观察吗啡的作用和腺苷及其受体阻断剂茶硷对其的影响。

White and beautiful skin has direct relation with black cells,especially melanin in them, which is classified into two categories: One is of inner origin, the other of outer origin.

皮肤的美白往往与黑色细胞的多少有直接关系。皮肤的黑色细胞可分为两大类：一类由肌体自身产生，称之为内源性；另一类从外部进入产生，称之为外源性。

Protein and calmodulin are two important signal molecules, they implicated in many cellular processes and have essential physiological functions in plant.

蛋白和CaM是植物细胞信号转导中的两个重要的信号组分，它们参与细胞的多种反应，具有重要的生理功能。

Methods The AGS cellseeded coverslips were prepared, then the two different status of Lactobacillus acidophilus and two different forms of Hp were added in different order. 2 hours later, the bacteria were Garm's stained, and the adherence of Hp to AGS cell were observed by microscope and the adherence index was calculated.

制备人胃上皮腺癌细胞系细胞爬片，将两种状态嗜酸乳杆菌和不同形态Hp菌分组按不同顺序加入，作用2 h，革兰染色后光镜观察分析Hp黏附指数产生的变化，荧光抗体染色法定性评价黏附于AGS细胞的Hp密度的改变。

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。
