查询词典 nerve cells

Chlamys farreri is a primary mollusc in evolution that a large number of NOS positive nerve cells must be located in the tissues of peripheral organs. The NOS in nervous system of scallop may play an important role in its nerve conduction and immune regulation.

栉孔扇贝进化上为较低等的贝类，NOS阳性神经细胞应主要分布于外周器官组织内，神经系统内大量的NOS可在其神经传导和免疫调节等方面发挥重要的作用。

Firstly, we introduce the basic theory and methods for realization of SOFM. Subsequently we improve the arithmetic and implement the feature extraction of raw data using K-L translation, select the eigenvector. Combining C-avarage and ISODATA arithmetic, classify the eigenvector, according to the methods of this dissertation, in lower layer, set nerve cell and unite or delete nerve cells in middle layer, to improve the anti-huise- and robust.

论文首先介绍了SOFM的基本原理和实现方法，接着在其基础上对具体算法进行改进，用K-L变换对原始数据进行特征提取，选取出特征变量，结合C-均值和ISODATA算法对特征变量进行预分类，按照本文中介绍的方法在底层预置神经元，在中间层对神经原进行合并和删除，加强了该网络的抗干扰性和稳定性。

AIM: To observe the effects of nerve growth factor on ALPactivity of human dental papilla mesenchyme cells.

目的：观察神经生长因子(nerve growthfactor，NGF)对人牙乳头间充质细胞ALP活性的影响。

A group of nerve cells forming a nerve center, especially one located outside the brain or spinal cord.

神经节一组形成神经中心的神经细胞，尤指位于脑或脊髓外侧的

They carry a nerve impulse across the gap between nerve cells.

他们携带着神经冲动越过神经细胞之间的间隙。

Sperry showed that the regenerated retinal axons always innervated the original sites of termination in the optic tectum. This experiment strongly disprove the resonance hypotheses proposed by Paul Weiss, who suggested that the nerve growth and synapse formation are largely random events, and the precision of connections between nerve cells emerged by selectively eliminating the inappropriate connections, only at later developmental stage.

Sperry的实验在支持Cajal假说的基础上，进一步明确发育过程中轴突的生长及突触的形成具有内在决定性，并且有力地反驳了当时占主流地位的由Paul Weiss于1930～40年代提出的resonance hypothesis，后者认为轴突的生长和突触的形成大多是一些随机事件，成年脑中的精确联系是通过对随机形成的不恰当联系进行选择地消除形成的。

Hours after operation, most nerve cells disappeared and the glial cells were degenerated. There were many mono-nucleus cells infiltrating in transplantation group while a few in control group. One week after operation, tissues in the infarction zone were liquescent with many monocaryons and lymphocytes infiltrating around them in control group.

术后48 h神经细胞大片消失，胶质细胞变性，自体骨髓干细胞移植组有大量单个核细胞浸润，对照组相对较少。1周后对照组梗死区脑组织液化变软，坏死灶周围可见较多的单核和淋巴细胞浸润；自体骨髓干细胞移植组大鼠部分坏死灶被新生毛细血管和胶质细胞增生修复，炎性细胞浸润不明显。

The differentiation of the newborn nerve cells in oculomotor nuclear after oculomotor nerve injury.

胚胎干细胞来源神经前体细胞在缺氧缺血性脑损伤海马内的分化。

On basis of mention , we investigate the ability of isolation, purification and expansion of adult rat mesenchymal stem cells to nerve cells in vitro.MethodsBone marrow mononuclear cells from adult rat femur and tibia were obtained sterilely by Percoll ( 1. 073 103 g/L ) gradient centrifugation .

根据MSCs与其它细胞的密度不同而采用Percoll(1.073×10~3g／L)分离液将其分离，此方法分离MSCs所获得的细胞种类较单一，Percoll分离液将骨髓细胞分为三层，取含MSCs的低密度层进行培养。

BACKGROUND: Basic fibroblast growth factor can accelerate the bone marrow mesenchymal stem cells proliferation and differentiation into nerve cells, which is considered as a mitogen of glial cells.

背景：碱性成纤维细胞生长因子可以促进骨髓间充质干细胞的增殖和向神经细胞方向分化，并被认为是胶质细胞的分裂原。

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。
