Methods The promoter of hTERT and Cox-2 was subcloned from human genomic DNA, then ligated to shuttle vector pd306 which contains the Ela and Elb gene of adenovirus to control the expression of Ela and Elb,respectively.

将hTERT和Cox-2启动子从人类白细胞基因组中亚克隆出来，并将启动子分别插入到腺病毒穿梭载体pd306上的E1A和E1B基因前，使hTERT和Cox-2启动子分别调控腺病毒必须基因E1A和E1B的表达，再将构建后的pd306和腺病毒的骨架质粒BHGE3在Ad293细胞内进行同源重组，并用重组后的病毒感染Hela细胞检测病毒对肿瘤细胞的杀伤力。

The epineurial vessels run along the nerves length and gave off branches, distributing along nerve bundle, to enter into endoneurium. The endoneurium contained only capillaries. Arteriolovenular anastomoses were few in trigeminal nerve root. The distribution of microvessels in trigeminal nerve root was uneven. The number of microvessels in the medial portion was less than that of the distant.

神经外膜血管沿神经根径向走行，沿途再发侧支斜行或横行入神经束之间，顺神经根束分布，并发侧支进入神经内膜；半月结内微血管围绕神经节细胞分布；三叉神经根内的微血管配布不均，其近侧端微血管数量较少，远侧端微血管数量较多。

Ambient salinity and dietary protein level only had significant interaction on the body ash content, while no significant interaction effects were observed in other parameters. Tubules of shrimp fed with CP30 and CP40 had the normal structure, though CP40 increased the number of R cells. Tubules of shrimps fed with CP20 had relatively fewer R cells and arranged incompactly. And the basal membranes of partial tubules were in disrepair. While tubules of shrimps fed with CP50 compactly arranged with much ambiguous materials in B cells.

饲料蛋白质含量明显影响了凡纳滨对虾肝胰腺的组织结构，投喂CP30和CP40饵料的对虾肝小体基膜完整，投喂CP40对虾的肝小体中还出现了大量的存储细胞；而投喂CP20饵料的对虾肝小体分布松散，R细胞数量较小，并且部分肝小体基膜破损；而投喂CP50饵料的对虾的肝小体排列紧密，且B细胞内出现大量内容物质。

Methods: By using JSB-1 with intramembranous antigen determinant as antibody, the positive rate as optimization index and MCF-7/A as model cells, cell pretreatment methods, such as the presence or Absence of FACS permeabilizing solution, the concentration of FACS permeabilizing solution, the time treating cells with FACS permeabilizing solution, the time incubating cells with JSB-1 working fluid, the time incubating cells with goat-anti-mouse IgG-FITC solution, and the conditions for keeping JSB-1 working fluid and cell numbers, were optimized.

This paper focuses on the stability study of Rhizopus oryzae IFO4697 when used for the methanolysis of renewable oils for biodiesel production. The results showed that water content was important for achieving high catalytic activity and good stability of the biocatalyst. The optimum water content was found to be 5%-15%. Both particle size and desiccation methods showed no obvious effect on the stability of the biocatalyst. With GA cross-linking pretreatment, the stability of the biocatalyst could be improved significantly. When Rhizopus oryzae IFO4697 repeatedly used for next batch reaction, direct vacuum filtration was found to be a good way for the maintenance of good stability of the biocatalyst.

本实验对固定化全细胞Rhizopus oryzae IFO4697催化植物油脂合成生物柴油的稳定性进行了系统地研究，结果表明：反应体系水含量对于全细胞催化剂的反应活性和催化稳定性有重要影响， 5%~15%含水量适宜；研究范围内，载体粒度及干燥方式对稳定性影响不显著；经过戊二醛交联后，全细胞催化油脂甲醇解反应的稳定性显著提高， 1200 h反应后，仍然可以保持75%的生物柴油得率；真空抽滤直接回用的方式有利于稳定性的保持。

Chk1 is one of the major checkpoint gene involved in G2/M checkpoint, as well as involved in G1/S and Intra S arrest. We use U937 human monoblastic leukemia cell as a model to study human Chk1 RNA isoforms and transcription regulation.
