Translation activity of this mRNA was measured in the wheat germ cell-free system.

研究了此mRNA在麦胚无细胞体系中的翻译。

Of the 5 patients with available follow-up, 3 were free of disease at 1, 5, and 8 years after orchiectomy (2 necrotic seminomas and 1 germ cell tumor, unclassified). One patient with yolk sac tumor (age 63 y) developed widespread metastases after 15 months and died of disease.

随访了5例患者，其中3例于睾丸肿瘤切除术后1、5和8年任健在且无复发（2例为坏死的精原细胞瘤、1例为未分类的生殖细胞肿瘤）。1例为内胚窦瘤（63岁），15个月后广泛转移，并死于本病。

It has been reported that gestational and lactational exposure to estrogens or androgen antagonists reduced testicular size and sperm production, germ cell apoptosis, male infertility, and male reproductive tract malformations, such as cryptorchidism, hypospadias, nipple retention, or reduced anogenital distance.

但本实验结果显示，大鼠孕期和哺乳期接触达母体中毒剂量的硫丹，对雄性子鼠的睾丸重量、每日精子生成量、附睾精子数和精子形态、睾丸生殖细胞凋亡发生率等都没有明显的影响，也未见雄性子鼠AGD缩短、乳头残留及隐睾和尿道下裂等雌性化表现。

BACKGROUND: Embryonic stem cells develop from early blastular inner cell mass. Under proper condition, ESCs can maintain undifferentiated state in vitro, normal diploid nuclear type, and proliferative potential. In addition, ESCs possess multi-directional differentiation capacity and can differentiate into all sorts of cells of three germ layers.

背景：胚胎干细胞来源于发育早期囊胚的内细胞团，适当条件下能在体外维持未分化状态、正常二倍体核型及无限增殖能力，且具有多向分化潜能，能够发育分化成机体3个胚层的所有类型细胞。

Chicken and quail intergeneric hybridization is a classic distant hybridization in fowl. In fowl science, chicken and quail belong to Aves, Galliformes, Phasiamidae, Gallus and Coturnix, and this hybridization combination has become the example of researching the incompatibility of different germ cell and sterile of distant hybridization.

鸡与鹌鹑杂交是属间杂交，其杂交种胚胎早期出现大量的死亡，并且杂交种出壳以前雌性胚胎全部死亡，这使鸡与鹌鹑杂交成为研究异种生殖细胞不亲和性和杂交种不育的典型。

The endodermal sinus tumor of the ovary stands first in the incidence of malignant germ cell tumors of the ovary in China.

卵巢内胚窦瘤的发生率在中国各类型卵巢恶性生殖细胞瘤中位居首位。

S inger argues to prenatal geneti c screening and gene selection to presume germ-line cell gene therapy.

基因治的种类及消极、积极基因治疗的界线问题，基因增强、优生学也是我们的重点。

Eight weeks latter, the left testes were harvested for detection of Johsen's score, ultrastructure of seminiferous tubules, intratesticular testosterone concentration and germ cell apoptotic index.

于VT8周后摘取各组大鼠左侧睾丸，检测其Johnsen's评分、生精小管的超微结构、睾丸组织的睾酮浓度和生精细胞的凋亡指数。

CaB participated in the human odontogen esis. Besides, the express of CaB in human toot h germ development was time-specific and cell-specific.

CaB参与了人釉质及牙本质的形成过程，并且在人牙胚发育过程中的CaB表达具有时间特异性及细胞特异性。

The Vg-negative reaction of the triploid female rainbow trout could not provide full evidence for the impossibility of liver to synthesize Vg. That Vg was not synthesized resulted from insufficient estradiol due to the retardation of ovaries development, the un-differentiation of follicular cells and the lost interaction of germ cell and somatic cells. It could be concluded from yolk genesis that the shortage of female triploid rainbow trout's Vg resulted from the abortive ooecium, but did not result in sterility.

由于三倍体雌性虹鳟卵巢发育受阻，无滤泡细胞分化，生殖细胞与体细胞的互作缺失，不能分泌足量的17β-E2以诱导Vg的合成，因而肝脏的Vg阴性并不能说明肝脏不具备合成Vg的能力，从卵黄发生的角度分析，卵黄蛋白原的缺乏不是导致三倍体虹鳟雌性不育的原因，而是其卵泡败育的结果。

You can do some assertiveness training.

你可以进行一些自信训练。

We were well on the path to making a rear-wheel-drive global platform," says Mays."

我们正致力于建立一个后轮驱动的平台，"Mays这样说道。"
