The recombinant eukaryotic expression vector pcDNA3.1-Myc-His B/tPA can stable express tPAcDNA in transfected hUVEC cell strains and can secret compt tPA protein. Experiment III The Effects of Transfected tPA Gene on Vascular Smooth Muscle Cells Proliferation and Migration in VitroObjective To investigate the effects of transfected tPA gene on vascular smooth muscle cell proliferation and migration in vitro and to provide a basis for further study on preventing vein graft restenosis.

结论构建的pcDNA3.1-Myc-HisB/tPA基因新型真核表达载体，能在HUVEC中表达，其表达具有高拷贝、稳定性好的特点，获得的表达蛋白活性较高，提示本载体和稳定表达tPA基因的人脐静脉内皮株能够作为基因治疗工具用于哺乳动物的实验研究。

The studies on the capacities of immune responses of lymphocytes in peripheral blood and immune organs of Grass Carp (Ctenpharyngoden idellus Cuvier et Valencinnes) to PHA and SPA with incorporation of 〓H-TdR and active reaction of Acid α-Naphthyl Acetate Esterase indicated that there were T and B lymphocytes in peripheral blood of grass carp, but only T lymphocyte and no B lymphocyte in the thymus of grass carp. It was justified that the T lymphocytes in peripheral blood was originated from the thymus, and B lymphocyte could be from the spleen and anterior kidney of grass carp.

运用〓H-TdR掺入法和酸性醋酸萘酯酶活性检测法分别研究了草鱼外周血以及免疫器官中的淋巴细胞对PHA和SPA的免疫应答以及化学标志特征，发现草鱼外周血中存在着类似于哺乳动物的T、B两类不同的淋巴细胞亚群；同时也发现胸腺中只有T淋巴细胞，而无B淋巴细胞，提示了胸腺中淋巴细胞可能是外周血中T细胞的来源，而B淋巴细胞可能来自脾脏或前肾。

P4 Antarctica is home to many seal species such as this fur seal. Its large eyes are designed to seek out prey in dim waters and are a slightly different shape to a land mammal's.

P4，南极是许多种海豹的栖息之地，就像这只毛皮海豹，它的大眼睛是用来在黑暗的海水中追寻猎物的，与陆地哺乳动物的眼睛形状稍有不同。

While relations between the two sides are still waiting to thaw, the area has become a winter migrating post for rare white-naped cranes, a haven for one-third of only 2,500 red-crowned cranes left in the world and home to almost 200 other species of birds and 52 species of mammals, including Korean water deer and Amur goral.

当双方的关系仍在等待解冻，这片地区已经成了珍惜的白枕鹤冬季迁移地，这里庇护世界目前尚存的2500种丹顶鹤中的三分之一，还是200多种其他鸟类和52种哺乳动物的家园，包括韩国獐和阿穆尔斑羚。

"All of these symptoms, and the underlying processes behind these symptoms that we're seeing in these dragonflies, are pretty much identical to what you see in mammalian metabolic syndrome and obesity," said Marden."We're seeing it all relate back to this non-inasie protozoan in the gut."

在蜻蜓观察到的所有症状及症状背后的代谢过程与哺乳动物的代谢综合征、肥胖极其相似" Marden说，"我们认为蜻蜓的这些症状与非侵入性的消化道原虫有关。

This, coupled with the use of limited marine biota data, may result in a higher-than-normal degree of uncertainty associated with the dietary exposure estimates and the overall marine mammal risk calculations.

这一点，再加上利用有限的海洋生物的数据，可能会导致高于正常程度的不确定性与食物暴露估计值和海洋哺乳动物的整体风险的计算结果。

Of, relating to, or designating the geologic time, rock series, sedimentary deposits, and fossils of the second oldest of the five major epochs of the Tertiary Period, extending from the end of the Paleocene to the beginning of the Oligocene, and characterized by the rise of mammals.

始新世的关于或标明第三纪的五个世中第二世的地质时代、岩系段，沉积矿床和化石的，该世由古新世末期到渐新世初期，以哺乳动物的繁盛为特征

The property is an outstanding natural laboratory for scientific research and provides a key ecological link to the Tropical Eastern Pacific for the transit and survival of pelagic fish and marine mammals.

这里是科学家研究的突出自然实验室，并为了远洋鱼和海生哺乳动物的输送和生存提供了炎热的东部太平洋的生态学的关键链环。

The cytoplasmic polyhedrosis virus of the silkworm is the prototype of a large group of animal, plant, fungal and bacterial viruses that contain segmented double stranded RNA.

以双链核糖核酸为基因组的病毒寄主范围很广，如哺乳动物的呼肠病毒，昆虫的细胞质多角体病毒，植物的水稻矮缩病毒，以及某些微生物的病毒，已经发现有十余种之多。
