Findings from these studies reveal that neural stem cells are self-renewing, multipotent progenitors that give rise to the diverse types of neurons and glia.

NTD的发生与神经干细胞的增殖、细胞的粘附分子、神经细胞的迁移等有关的分子信号的改变或作用途径被阻断密切相关。

PTEN mainly expressedin neurons in our experiment and the absence of PTEN expression in glia may be relatewith the development of gliomas.

PTEN可能主要在神经元中表达，其在胶质细胞的缺失可能和神经胶质瘤的发生发展有关。

Within these two neurogenic niches, specialized astrocytes are neural stem cells, capable of self-renewing and generating neurons and glia.

在这两个神经发生的微环境中，神经干细胞可分化为特定的星形胶质细胞，能够自我更新并产生神经元和神经胶质。

All of these functions occur through the interaction between glycans on glycoprotein or glycolipid displayed on cell surfaces with specific lectins, antibodies, or proteins.

这些功能皆透过特定的凝集素、抗体或蛋白质与细胞表面上醣蛋白或醣脂质末端的醣类分子发生交互作用所引发的。

In addition, goblet cells have been shown to wax and wane over the natural history of BE.

此外，杯状细胞在BE发展过程中体积会发生改变。

Objective To study the effects of prolactin on HLA-DR and CD40 expressions by human thyrocytes,and to investigate the possible mechanisms for PRL to affect the development of Graves'disease.

目的研究催乳素对人甲状腺细胞表面HLA-DR和CD40表达的调节作用，以探讨PRL影响Graves'病发生、发展的可能机制。

Collaborating with Rong Zeng's group in Institute of Biochemistry, SIBS and Brian Barnes' group in University of Alaska, USA, Yan's group in PICB systematically investigated the global protein expression changes during the hibernation of Arctic ground squirrel.

计算生物学所严军课题组与生化细胞所曾嵘组以及美国阿拉斯加大学Brian Barnes等人合作，结合之前在动物冬眠中mRNA水平研究的基础，系统研究了北极地鼠在冬眠中蛋白质表达发生的整体变化。

But the disease occurs only in those who have two copies of the gene for the disease-causing haemoglobin.

但这种镰状细胞性贫血症只会发生在同时有两组这种致病的血红蛋白的人身上。

In about 30 per cent of cases, however, there is no family history of haemophilia, these cases arise as a result of new mutations occurring in the cells that produce eggs or sperms in the parents.

在大约30 ％的情况下，不过，有没有家族病史，血友病，这些个案出现，由于新的基因突变发生在细胞产生卵子或精子在家长。

From ultrastructure of RBC which co-cultured with HAP|,HAP4,HAP5,we have observed that HAPi and HAP4 can induce RBC membrane to deform and decrease stability of RBC membrane, so the particles can enter intramembrane, as a result, intracellular hydroxyapatite nanoparticles may heighten the concentration of Ca2+ and effect structure of membrane protein, membrane lipid and hemoglobin, subsequently,the deformability of RBC decreased all the better and leaded to erythrocyte aggregation. However,HAP.s uniformly dispersed around cell and didn't adhere to it,also, cytomorphosis cannot be found.

观察HAP_1，HAP_4，HAP_5与细胞作用后红细胞的超微结构中，HAP_1与HAP_4引起红细胞膜变形和膜稳定性下降，粒子进入胞内，进入胞内的HAP纳米粒子可能升高胞内Ca~(2+)浓度，从而影响膜蛋白、膜脂、血红蛋白的结构，使红细胞变形性进一步下降，最终导致聚集的发生。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
