卵黄

The first passage of YS-MSCs which grew in good condition was obtained, and adipogenic differentiation of YS-MSCs was induced by dexamethasone and insulin, and angioblast was induced by vascular endothelial growth factor and basic fibroblast growth factor.

取生长状态良好的第1代细胞，以地塞米松、胰岛素定向诱导卵黄囊间充质干细胞向脂肪细胞方向分化；以血管内皮生长因子和碱性成纤维细胞生长因子体外诱导其向血管内皮细胞方向分化。

BACKGROUND: Compared with adult mesenchymal stem cells, yolk sac-derived MSCs of early embryo have stronger self-renewal capacity and plasticity. Moreover, they could differentiate into angioblast and hemopoietic stem cells during embryonic development and trigger embryonic angiogenesis and hemopoietic tissue development.

背景：与成体间充质干细胞相比，来源于早期胚胎的卵黄囊间充质干细胞有更强的自我更新能力和可塑性，且在胚胎发育过程中可分化为成血管细胞和造血干细胞，启动胚胎血管发生和造血组织发育。

Immunohistochemically, the tumor cells were strongly positive for α fetoprotein and α antitrypsin.

发生于心脏的卵黄囊瘤是极为罕见且高度恶性的，它的诊断主要依靠病理组织学及免疫组化检查。

A correction factor for vitellogenic atresia was included based on the level of atresia and the size of atretic oocytes in relation to normal oocytes finding that OPD would be biased when smaller atretic oocytes are present but not accounted for.

卵黄闭锁的相关因素包括闭锁水平和与正常卵母细胞相关的闭锁卵母细胞的大小，发现当较小的闭锁卵母细胞出现而不计算在内时 OPD 会有偏差。

According to amino acid sequence to vitellin which has the structural character of GL/ICG motif near C end, two degenerate primers were designed and Chrysopa septempunctata s RNA was extracted, and a 900bp fragment was amplified by RT-PCR.

根据昆虫卵黄蛋白氨基酸序列在靠近C端存在GL／ICG区域的结构特点，设计了两条简并引物，提取大草蛉的RNA，用Takara的3′—RACE试剂盒进行RT-PCR，扩增出一段900bp的片断。

The titer variation to juvenile hormone of female worms was detected by GC-MS system, from which there was an obvious correlation between variation regularity to juvenile hormone and vitellogensis's regularity in Chrysopa septempunctata.

通过GC-MS系统测定了大草蛉雌虫体内保幼激素Ⅲ滴度的变化，从中可以看出大草蛉体内保幼激素滴度的变化与卵黄蛋白发生存在明显的相关性。

The titer variation to juvenile hormone of female worms was detected by GC-MS system, from which there was an obvious correlation between variation regularity to juvenile hormone and vitellogensiss regularity in Chrysopa septempunctata.

通过GC-MS系统测定了大草蛉雌虫体内保幼激素Ⅲ滴度的变化，从中可以看出大草蛉体内保幼激素滴度的变化与卵黄蛋白发生存在明显的相关性。

The technology for purifying triple serum antibody and yolk antibody against Newcastle disease, colibacillosis and paretyphus avium in chicken has been established.

对抗鸡新城疫ND、大肠杆菌病AC、副伤寒PA三联血清抗体和抗鸡新城疫高免卵黄抗体进行了提纯工艺研究。

Chickens colibacillosis is a focus or systemic infectious disease, which is caused by E.coii ,with complicated antigens, multiple serotype and various clinical symptoms such as salpingitis, synovitis, and so on. Colibacillosis often happens together with various diseases and has been spread everywhere in Haian county in different extent..

鸡大肠杆菌病乃是由大肠埃希氏菌所引起的局部或全身性感染的疾病，其抗原性复杂，血清型多样，临床症状和病理变化多变，包括大肠杆菌性败血症、大肠杆菌性肉芽肿、气囊炎、肿头综合症、腹膜炎、输卵管炎、滑膜炎、全眼球炎及脐炎、卵黄囊炎等。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
