神经形成

We found that the induction of long-term facilitation by repeated applications of serotonin, a modulatory transmitter released during learning in Aplysia, requires upregulation of kinesin heavy chain in both pre- and postsynaptic neurons.

在重复利用血清素长期诱导下，作者发现在海蜗牛感应形成时，一种调节传送体被释放出来，而这一过程需要在神经联会前后都具有上调的驱动蛋白重链。

To explore how gene products, required for the initiation of synaptic growth, move from the cell body of the sensory neuron to its presynaptic terminals, and from the cell body of the motor neuron to its postsynaptic dendritic spines, we have investigated the anterograde transport machinery in both the sensory and motor neurons of the gill-withdrawal reflex of Aplysia.

为了探索突触形成起始阶段所需的基因表达产物，由感知神经细胞体向脊柱终端，以及由驱动神经细胞体向联会后枝状脊柱的移动，研究人员对与海蜗牛腮回退反射有关的，感知和驱动神经的顺式传递装置。

A systematic method has been established for primary cultivating of cortical neurons. Observations indicated that the cortical neurons were affixed to the culture after 4h, and the nerve cells had 1-2 small processes. The Nissl's staining results show that the purity(≥92%) of the cortical neurons rose apparently on days 3 and 6 post-beginning of culturing with Ara-C inhibition. The MTT experiment show that the viability of the neurons was the highest,and they are oval,araneiform and pyramidal and formed an integrated neural network on day 6 post-beginning of culturing.

光学显微镜观察结果表明，培养至第4h绝大多数神经元已贴壁生长，胞体上可见1~2个细小突起；培养至第3d、第6d时，Nissl's 染色结果显示，加Ara-C能显著提高神经元纯度（≥92%）；MTT结合形态学观察结果表明，神经元培养至第6d时活性最强，细胞呈卵圆形、蜘蛛状、锥体状等多种形态，细胞胞体饱满，光晕明显，神经网络形成完整。

There were infiltration of inflammatory cells inside nerve tissue and perivascular cuffings in HE staining. In trichrome staining, the axon with inhomogeneous chromatosis was swollen and beaded-discontinued; The myelin was porous and partly disaggregated.

HE染色发现神经组织内炎细胞浸润，血管&袖套&样病灶形成；三色染色可见轴突肿胀，呈串珠状，且不连续，着色不均匀；髓鞘结构层次紊乱，疏松，崩解。

Wounds such as road accidents, gunshot injuries, fire burns and some internal medicine diseases like diabetes, tumors and palsies always accompany with muscle injuries. Muscle regeneration is relatively difficult on the conditions of serious and large area of muscle injury or loss. Finally the raw surface will be replaced by fibrous connective tissue and form scar, which may disenable the movement of body and badly influence nerves and blood-vascular system, and eventually develop into obduracy wound.

各种创伤如车祸伤、枪弹伤、烧伤及部份内科疾病如糖尿病、肿瘤和瘫痪所致的肢体坏疽都常伴肌组织损伤，对于严重或面积较大的肌损伤或缺损，肌肉的再生相对困难，创面最终被纤维结缔组织替代而形成瘢痕，导致机体运动功能障碍并累及神经、血管系统，影响患者的预后和生活质量。

Depending on the clinical situation, the goals of such surgery may include spinal cord or nerve root decompression, restoration of sagittal alignment, and avoidance of complications such as pseudarthrosis, anterior graft dislodgement, and adjacent segmental degenerative disease.

跟据临床情况，这些手术的目的可能包括脊髓或神经根减压、矢状面排列的恢复和避免并发症，如假关节形成、前方植骨块的脱出和临近节段的退行性疾病。

At the beginning of the PNS development, the proneural genes are expressed in patches of ectodermal cells and endow these cells with competence to become sense organ precursors.

感觉器官的发育始於原神经基因的短暂表达於原神经细胞群和感觉器官前细胞，进而赋予感觉器官前细胞形成感觉器官的能力。

The structure formation factors S were calculated from 19 groups of experimental data of a new high strength toughness steel s on the basis of the empirical electrionic theory of solids and molecules, and 16 groups of which selected randomly were applied to train with BP network of artificial neural networks and other three groups were used to examine.

根据固体与分子经验电子理论计算了 19组新型高强韧钢的试验数据所对应的结构形成因子 S值，从中随机抽取 16组数据，应用人工神经网络的 BP结构进行训练，用其余 3组数据进行检验，其平均训练误差为 0 。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.
