Bamboo mosaic virus encodes a 155-kDa replicase that the middle region contains a helicase-like domain according to the existence of several conserved featured motifs of helicase. Previous studies showed that the helicase-like domain exhibits both ATPase and RNA 5'-triphosphotase activities, and Mg2+ is essential for both activities. Mutagenesis of conserved motifs showed these amino acids play important roles for enzymatic activities. These results suggested that the properties of this denatured and renatured protein are coincident with other SF1 helicases.

从胺基酸序列分析显示，竹嵌纹病毒复制酵素中间区域的类解螺旋酵素具有解螺旋酵素的保留性胺基酸区域，经实验显示此蛋白具有ATPase和RNA 5'-triphosphatase活性，而且是依赖镁离子进行反应的，其中保留性胺基酸的突变会破坏其催化能力，说明这在大肠杆菌表达的蛋白质经过变性及重新摺叠的过程，具有和其他SF 1解螺旋酵素相似的特性。

Results GDNF plays extensive roles in the development and disease of motoneuron.

胶质细胞源性神经营养因子(glialcellline-derivedneurotropicfactor，GDNF)最初是从大鼠胶质细胞系B49的条件培养基中分离纯化获得的一个新的神经营养因子，GDNF为分泌性碱性蛋白质，在中枢神经系统和周围器官中有广泛分布，其表达受不同的转录因子等调控。

Because it is a hard work to refold the denatured inclusion proteins correctly, especially for those which contain several disulfide bonds. the results?repeatability of some activities is not very perfect.

纯化包涵体后，将产物变性成可溶形式，然后用Ni-NTA对表达产物纯化，SDS-PAGE检测为一条带，包涵体的复性是一项非常困难的工作，尤其是对含有多对二硫键的蛋白质，因此复性后冻干，测它的某些活性时，结果的重复性不太理想。

According to Chair of Department of Neurology, Taipei Veterans General Hospital, Shuu-Jiun WANG, the activation of trigeminal vascular system in the brain is commonly regarded as the pathogenic mechanism for sick headache and cluster headache. Stick to this premise, the research team hypothesizes that the system activator Nociceptin and the system inhibitor Orexin A these two kinds of neuroproteins are related to the pain degree of migraine and cluster headache.

北荣神经内科主任王署君表示，脑内三叉神经血管系统活化与否，是医界公认的偏头痛与丛发性头痛致病机转，故研究团队推测，可活化该系统的致痛素，以及抑制该系统的下视丘素两种神经蛋白质，应与偏头痛与丛发性头痛的程度有关。

We are interested in the molecular mechanisms underlying neuronal migration and our work published in 1999 indicates that there are diffusible molecules in the brain which can guide the direction of migrating neurons; specifically, a secreted protein called Slit is repulsive to neurons and its concentration gradient guides neuronal migration.

我们在分子水平对这个问题进行了研究。1999年发表的结果给出这样一个答案：脑内存在导向性分子，可以指导神经细胞的迁移方向；具体的发现是，一个叫Slit的分泌性蛋白质，对神经细胞有排斥性作用，它的浓度梯度指导神经细胞迁移的方向。

He fatty acid composition of grass carp was analyzed using GS-MS and more than 18 fatty acids were identified, including hexadecanoic acid, 9-hexadecenoic acid, 9-octadecenoic acid, 6,9-octadecadienoic acid, 9,12,15-octadecatrienoic acid, octadecanoic acid, 5,8,11,14-eicosatetraenoic acid, 4,7,10,13,16,19-docosahexaenoic acid, 5,8,11,14,17-eicosapentaenoic acid, pentadecanoic acid, heptadecanoic acid, and 5,8,11-heptadecatrienoic acid. There were some fatty acids with odd carbon atoms besides the fatty acids with even carbon atoms common in animals and plants.

P能改善蛋白质的乳化性和凝胶性。3、利用GC-MS对草鱼鱼肉中的脂肪酸进行分析，鉴定出草鱼中含有棕榈酸、十六碳烯酸、油酸、亚油酸、亚麻酸、硬脂酸、花生四烯酸、DHA、EPA、十五烷酸、十七烷酸、十七碳三烯酸等十八种以上脂肪酸，除含有动植物中常见的偶数碳脂肪酸外，还含有一定量的奇数碳脂肪酸。

Under the basis of physiological data, a non-linear and unsteady comprehensive mathematical model of microcirculatory dynamics with distributed parameters is developed. Hemodynamics, interstitium dynamics, lymph dynamics, dynamics of protein transport, oxygen dynamics, dynamics of heat transfer, and myogenic and metabolic regulation procedures are included. The interactions between these factors are comprehensively exhibited. The influences of arteriolar vasomotion and non-linear viscoelasticity of blood in arteriole are considered.

根据微循环系统的生理情况，建立了微循环系统动力学非定常、非线性分布参数模型，包括血液动力学、间质动力学、淋巴动力学、蛋白质传输动力学、氧动力学、热量传输动力学和肌原性与代谢性调控过程，综合反映了它们之间的相互作用，并考虑了微动脉自律运动和血液非线性粘弹性的影响。

The results showed that the insufficiency rate of calorie,protein,vitamine B1, B2,C,calcium and iron was significantly decreased after the education (P＜0.05),especially in the soluble vitamines.

结果表明，计划实施后热量、蛋白质、维生素B1、维生素B2、维生素C、钙和铁的缺乏率明显下降(P＜0.05)，下降幅度较大的是水溶性维生素；两组患者的入院和出院体重比较均无明显差别，但两组患者入院和出院的体重差值有显著性差别(P＜0.05)。

Therefore the denatured protein could pass along the gradient and refolded to native conformation as urea was gradually removed and a linear removal of urea was realized in this manner.

在与常用复性方法的比较中，这种方法在模型蛋白质溶菌酶的复性实验中初步显示出了一定的优越性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
