文昌鱼是介于无脊椎动物和脊椎动物之间的过渡类型，是研究动物进化和胚胎发育的典型材料。

In contrast, anhidrotic mice did show a reduction in membrane AQP5 expression in sweat glands after topiramate delivery. To our best knowledge, the present study is the largest sample-size clinical investigation concerning topiramate induced-hypohidrosis.

Traditional morphological studies have resulted in few solid conclusions regarding the monophyly and systematic position of Myriapoda within Arthropoda; the origin and evolutionary history of Myriapoda are also veiled by the sparsity of the group's fossil record.

基于表型性状的系统学研究中，多足动物亚门在节肢动物门中的系统分类和单系性等问题一直存在争议；化石记录的稀少又使多足动物的起源及演化历史变得迷雾重重。

In their habitat researchers have found fruit pits, the fig, bitter almond and so on. They haven't seen any mark of insects, rodents and birds. Snails perhaps are the only creature eaten by the giant lizard.

研究人员在它们的栖息地发现各种水果核、无花果以及苦杏仁等，但没有任何昆虫、啮齿动物以及鸟类痕迹，蜗牛可能是这种巨蜥吃过的唯一一种动物。

One embryonic cell can be separated into many blastomere cells. As be the nuclear donor of the embryonic cell nuclear transfer, it can breed the number of eminent species largely, increase the number of endangered animals, supply large number of supply same genotype animals, improve the efficiency of gene transfer and sex control and offer same genotype apparatus or organ for human transplant.

一个早期胚胎细胞可以分离多个卵裂球，以此作为核供体进行胚胎细胞核移植，可以大量扩繁优良品种的数量，增加濒危动物的数量，为科学研究提供大量遗传同质的动物，提高转基因和性别控制技术的效率，提供基因型相同的器官或组织供人类移植。

The scientists studied videos of seven different kinds of winged beasts , from bluebottle flies to a cockatoo .

科学家们研究了7种不同有翼动物的录像，这些有翼动物包括从丽蝇到凤头鹦鹉，不一而足。

Based on the analysis on brachiopod fossils of the late middle Permian,the brachiopod extinction in Pre-Lopingian event of late middle Permian in this area can be divided into two sub screens: the first screen in the end of earlier Wushisanti Subage a...

通过川渝地区中二叠世晚期的腕足动物化石资料的研究，表明本地区中二叠世晚期的乐平世事件中腕足动物的灭绝可划分为前后2个不同的次级幕：早期的五十三梯亚期之末的第一幕和晚期的倒钻岩亚期之末的第二幕，且第二幕的灭绝规模要比第一幕更大。

Three infectious bronchitis virus isolates named as Q1, J2 and T3 were isolated from proventricular tissue taken from vaccinated chicken flocks in China The biological characteristics of the three isolates were observed.

In addition, there have no enough studies in the mechanism of spermatogenesis arrest induced by heat, and also there are many negative effects in the male contraceptive methods during these years like surgical ligation of vas deferens. All these factors have brings researchers to found a safety and efficacy methods for the problems in male reproduction.

因此，本研究通过高温处理未成年动物的模型，从细胞及分子水平探讨高温作用后生精功能障碍的机理，并对高温引起不育的机制进行深入研究；这些研究对阻止、延缓或减弱上述因素对人类生育能力的损害有重要意义，同时也为临床治疗一些男性不育、指导未成年男性生殖保健和探索男性避孕措施的研究提供理论基础。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
