查询词典 nerve cells

A couple of years ago, the research group had been already able to prove that these glia cells function as stem cells during development. This means that they are able to differentiate into functional nerve cells.

两年前，该研究小组已经证实这些胶质细胞在发育过程中具有干细胞功能，即意味着它们可分化为功能性神经细胞。

Dr Yamanaka's team has, for instance, been able to persuade its stem cells to turn into nerve cells and heart cells.

Tranquilize the mind and improve sleep, and nourish the nerve: Royal Jelly contains three amino acids that are the neurotransmitter for brain, like glycine that can inhibit the cerebral nerve activity, like glutamic acid and aspartic acid that can excite the nerve cells.

镇静安眠、滋养神经，王浆中有3种氨基酸是大脑的递质，甘氨酸能抑制脑神经细胞的活动，天冬氨酸和谷氨酸都能兴奋神经细胞，对预防自主神经功能而引起的头晕、恶心、食欲不振等综合症有奇效。

This cancer starts in the glial cells, which are cells that help nerve cells work.

它起源于胶质细胞，这是帮助神经元进行正常工作的一类细胞。

Under the regulation of different growth factors, they can differentiate into many kinds of cells, such as hepatocyte-like cells, cardiomyocyte-like cells, neuroglial cells, nerve cells, pancreatic islet-like cells and so on.

尽管如此，仍还不能将人羊膜上皮细胞称之为严格定义上的干细胞，因其不具有长期的自我更新和产生单个细胞克隆的能力，此外人羊膜细胞在体内分化成有功能的各种细胞类型需要进一步研究证实。

After being induced to differentiate in vitro, cells with various morphologies showed β-gal activity, including nerve cells, neuroglial cells, epithelial cells. We also detected β-gal activity in a wide variety of tissue elements in solid tumors made by injecting the MC15 and MA34 cells into syngenic mice. Then we produced chimeric embryos by injecting the MC15 cells into Kunming blastocysts and recovering the embryos at various developmental stages.

SiCMVIE(Simian Cytomegalovirus Immediately Early)启动子是一个强启动子，本文首次将SCMVIE启动子应用到ES细胞途径上制作嵌合鼠，并通过lacZ基因在ES细胞和早期嵌合胚胎中的表达，表明该启动子是一个能在小鼠多数组织表达的启动子，这与1993年Peppel等人用原核显微注射法获得的转基因小鼠上所得的有关结果是基本上是一致的。

Results:① Neuroglobin-immunocreactive positive cells were detected in cortex, thalamencephalon, hippocampus, hypothalamus, cerebellum, brain stem and spinal cord;② Ngb-IR positive nerve cells were also detected in peripheral nervous system such as intramural ganglia, myelinated nerve fiber and retina;?Substantial Ngb protein expression was also found in metabolically active endocrine tissues such as the pituitary gland , adrenal gland and testis.?

结果：(1)在所观察的大脑皮质、海马、丘脑、下丘脑、脑干、小脑和脊髓神经细胞都出现Ngb蛋白免疫阳性反应，不同区域表达强度不同：(2)在外周神经系统的神经节、有髓神经纤维和视网膜也观察到Ngb免疫阳性反应；(3)垂体、肾上腺、睾丸也可见到Ngb-IR阳性细胞。

The spinal cord samples were hemisected and they were randomly divided into three groups: the control group, the olfactory ensheathing cell group, and the olfactory ensheathing cells and the nerve growth factor group.

目的：探讨大鼠嗅粘膜嗅鞘细胞（olfactory ensheathing cells， OECs）移植联合神经生长因子(nerve growth factor， NGF)修复脊髓急性损伤的可行性和疗效，并观察二者的协同作用。

Input-layer contains seven nerve cells (sailor average maritime experience、average shipping years、average standard wind days、average river velocity 、visibility、water depth and traffic density) and output-layer contains four nerve cells (great accident、large accident、common accident and small accident).The test that use the data of historical occurrence level of maritime accidents in ChongQing water area is done, the result shows the feasibility of the predictive model.

最后本文用VC++制作界面，基于MATLAB的神经网络工具箱建立了水上交通事故的BP神经网络预测系统，采取三层BP神经网络，输入层有7个输入神经元(船员平均水上资历、平均船龄、平均标准风天数、水域平均流速、能见度、水深和交通密度)，输出层有4个神经元(重大事故、大事故、一般事故和小事故)，并通过对长江干线重庆水域的预测来检验模型的效果。

Serotonin and noradrenalin cause nerve cells to send impulses along to other nerve cells, and thus increase the activity in the brain.

去甲肾上腺素和血清素引起神经细胞发出的神经冲动沿其他细胞从而增加脑部活动。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
