BACKGROUND: Myelination following axonal regeneration is a key factor affecting the recovery of spinal cord injury.

背景：轴突再生后髓鞘化是影响脊髓损伤后恢复的一个关键性因素，而少突胶质细胞存活的多少直接影响轴突再生后髓鞘化。

Endogenous BDNF affected myelination of postnatal peripheral nerve through p75 and NP-kappa B signal transduction pathway.

内源性BDNF影响出生后大鼠周围神经的髓鞘化，尤其在早期作用明显；内源性BDNF主要通过p75和NF-κB信号途径调节出生后大鼠周围神经的髓鞘化。

But, deep myelination, or the erosion of the protective sheath around the axons of neurons, may not be reversible if B-12 deficiency is severe or long-term, she said.

但是，她说，如果长期严重缺乏B12，一旦髓鞘已经形成，或神经原轴突周围的保护性鞘已受侵蚀就是不可逆的了。

Based on long-term monitoring convergence deformation of Wuqiaoling tunnel, this paper analyzes convergence deformation regular of two parallel main tunnels.

本文在对乌鞘岭隧道进行长期围岩收敛变形的基础之上，分析了乌鞘岭左右两主洞的收敛变形规律。

And it has also been demonstrated that acid sphingomyelinase, an enzyme responsible for hydrolyzing sphingomyelin to generate ceramide, could be activated at the same time.

同时，一种可以水解鞘脂类物质产生神经酰氨的酸性鞘磷脂酶往往在此过程被激活，这些过程对于胞内信号转导具有重要的作用。

Sphingomyelin is a kind of lipid, residing in the nature food and having latent function of inhibiting cancer. Sphingomyelin is metabolismed to ceramide and sphingosiine in the colon.

鞘磷脂是存在于天然食物中的一种具有潜在抑癌作用的脂类，在结肠内被代谢为神经酰胺和鞘氨醇。

As the precursor of sphingolipids, sphingosine is one of important constituents of cell membranes.

鞘氨醇是生物体内合成鞘脂的母体化合物，是生物膜中的重要组分之一。

The total syntheses of sphingosine , ceramide and glycosphingolipid were reviewed with emphasis on the recent progresses.

综述了神经鞘氨醇、神经酰胺及鞘糖脂全合成研究的基本概况，重点评述了其最近的研究进展情

Two weeks later, we measured the degree of the inclined plane and analyzed electrophysiological parameters such as latency, stimulus threshold and amplitude of MEP-C.

目前，多项研究表明OECs有促进轴突再生以及使脱髓鞘轴突重新髓鞘化的作用，因此有希望成为治疗脊髓损伤的一种新工具。

The wavelet variance verification also indicates that the first main period of the runoff of mountainous watershed in the Shiyang River Basin is 30years, and 22years and l5years are the second and third period respectively; 3 Then we also compared the total runoff of mountain watershed with climate factors of Wushaoling which station is in the mountain headstream area, such as precipitation and temperature, the data record that the correlation coefficient of annual runoff and precipitation variation over the upper reaches in the Shiyang River Basin is 0.61 ,which indicates precipitation is the main water recharge of the runoff.

石羊河流域出山口年径流的周期变化与乌鞘岭站年降水量和年均气温周期基本上都能在同一周期上下浮动，其中出山口年径流量与乌鞘岭山区年降水量相关系数为0.61，说明地表径流量主要是由山区降水补给；年径流量与山区年均气温变化呈0.28的反相关，说明该流域近50年来出山口径流与山区气温呈反比，即径流量随年均气温上升而减少，相关性暂时不十分明显。

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。
