Complementation analysis reveals a potential role of human ARV1 in GPI anchor biosynthesis 下载免费PDF全文

ARV1 is involved in regulating lipid homeostasis but also in the biosynthesis of glycosylphosphatidylinositol (GPI) in Saccharomyces cerevisiae. Here, we examined whether human ARV1 can complement the role of yeast ARV1 in GPI biosynthesis. Overexpression of human ARV1 could rescue the phenotypes associated with GPI anchor synthesis defect in the yeast arv1Δ mutant. The results suggest that Arv1 function in GPI biosynthesis may be conserved in all eukaryotes, from yeast to humans. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

为研究结构在地震过程中动力特性变化和损伤过程,为结构地震损伤评估提供可靠依据,采用递归式在线系统辨识算法RARX模型,利用结构强震记录识别了结构时变模态参数。以一座6层钢筋混凝土框架结构为例,识别了其时变自振频率、阻尼比和等效刚度。结果发现:在小地震动作用下,结构自振频率随时间几乎不发生改变;在大地震动作用的整个时间过程中,结构自振频率随时间逐渐降低,降低到一定程度到达最低点后,频率开始回升,直至地震结束,但最后不能回升到初始值,说明经历大震发生损伤的结构在震后性能会有所恢复;结构等效刚度变化趋势和自振频率相同,但在大震中下降比频率下降大的多;结构阻尼比在经历大震发生损伤后增大。结果可供结构地震损伤预测及结构震后安全鉴定参考。 相似文献

The trend in current and near future energy consumption from a statistical perspective 总被引:3,自引:0,他引:3
Energy consumption has increased remarkably over the past half century mainly due to increasing population and economic development. The influences of these two factors are considered. In most developed countries, such as Japan, France, Germany and Korea, the growth rate of energy consumption is due to economic development. The effects of population in Germany and Japan will substantially decline. In the USA, it is due to both factors as well as in the developing countries, such as China, India, Indonesia and Latin America. Economic success is more effective than increasing population in China, India and Indonesia, while both factors are roughly equal in Latin America. In Africa, though the growth rate depends on the effect of increasing population, its contribution to world energy consumption is small. On a worldwide scale, the growth rate of energy consumption will be affected by improving standards of living. 相似文献

We show that anyk-connected graphG = (V, E) has a sparsek-connected spanning subgraphG′ = (V, E′) with ¦E′¦ =O(k¦V¦) by presenting anO(¦E¦)-time algorithm to find one such subgraph, where connectivity stands for either edge-connectivity or node-connectivity. By using this algorithm as preprocessing, the time complexities of some graph problems related to connectivity can be improved. For example, the current best time boundO(max{k 2¦V¦1/2,k¦V¦}¦E¦) to determine whether node-connectivityK(G) of a graphG = (V, E) is larger than a given integerk or not can be reduced toO(max{k 3¦V¦3/2,k 2¦V¦2}). 相似文献

Some of the interim results of the Bench Mark Project by the Subcommittee on the Inelastic Analysis and Life Prediction of High Temperature Materials, JSMS, is presented. The purpose of the present bench mark study is to review and evaluate the inelastic constitutive models relevant to material response under the plasticity-creep interaction.By specifying normalized and tempered steel at 600°C, sixteen bench mark problems of four categories are first established: (I) tensile stress-strain relations and creep curves, (II) material response under mixed modes of plastic and creep loading, (III) ratcheting and deformation under program loads, and (IV) cyclic deformation behaviour under the combination of different strain rates. Then, the outline of seventeen inelastic constitutive models of nine types discussed in this project is presented. Finally, the interim results of these bench mark tests are compared with the corresponding predictions of the constitutive models to evaluate their accuracy in simulating the actual behaviour of the material. 相似文献

Mixed type hepatoma with two components, hepatocellular and cholangiocellular carcinoma, is very rare. We encountered a case of a single and minute mixed type hepatoma developing on liver cirrhosis in a patient with persistent hepatitis C viral infection. Histologically, the two-type cancer tissue existed in a nodule with a maximal diameter of approximately 20 mm, and the cholangiocellular carcinoma occupied about 70% of the tumor. The original cell of the mixed type hepatoma is unknown, but this case suggests that a bipotential cell developing into hepatocellular and cholangiocellular carcinoma may be the origin. 相似文献
