查询词典 oocytes

To eplore the relationship between Dynein and the formation of meiosis error of oocytes, the immature mouse oocytes were in vitro cultured with a known dynein ATPase activity inhibitor- sodium orthovanadate to detect the changes of maturation rate, and semi-quantitative RT-PCR and single cell RT-PCR were performed to detect the alteration of the cyclin B1 mRNA level.

为探讨Dynein与卵母细胞减数分裂错误形成的关系，采用小鼠卵母细胞体外培养成熟技术和半定量RT-PCR方法，分别检测Dynein抑制剂-原钒酸钠对卵母细胞成熟率和cyclin B1基因转录水平的影响。

A23187 and OA could parthenogenetically activate Urechis unicinctus oocytes and activate MAPK, indicating that the effect of fertilization on GVBD and activation of MAPK was mediated by rising in intracellular free calcium, and phosphorylation of some proteins was enough to activate the oocytes.

钙离子载体A23187和OA可以孤雌活化单环刺螠卵母细胞并激活MAPK。说明：①受精是通过钙离子的内流来激活卵母细胞并使MAPK活化的。②某些蛋白质的磷酸化状态对减数分裂是必要而且在一定程度上是充分的。

This antibody cross-reacted with the Vasa signals in the perinuclear nuage-like structures of young oocytes and some oocytes bearing early and mid-vitellogenesis.

实验结果显示在刚分化的卵母细胞以及在卵黄生成早、中期的卵母细胞，较集中的Vasa讯号出现在核膜周围。

The cleavage and pronuclear formation rate of oocytes treated with 5μmol/L Ion were significantly higher than that of oocytes with EH treatment.

结果发现，5μmol／L Ion激活处理水牛卵母细胞分裂率（63.0％vs 54.2％，P＜0.05）及原核形成率显著高于EH处理的卵母细胞。

Even though the older oocytes were easier to activate and developoed more rapidly to the pronuclear stage than younger ones after artificial stimulation, the percentage of blastocyst development was lower than that in younger oocytes.

大龄卵比小龄卵易于激活而且形成原核的速度比小龄卵快，但卵激活后发育至囊胚的比例较小龄卵低。

Here were expression of TGFαand EGFR mRNA in unmatured oocyte, matured oocyte, embryo and the expression of TGFαand EGFR in matured oocytes were comparatively more abundant than that in unmatured oocytes.

GFαmRNA的量在8细胞期下降到最低水平，并随着胚胎基因组的激活胚胎开始转录TGFα，使TGFαmRNA表达总量保持在一定水平，持续到桑椹胚期；EGFR mRNA的量在胚胎发育到桑椹胚期下降到最低，而囊胚期胚胎中的整体表达量又上升。

The results indicated: 1 .There is obvious difference between the gonads of precocious and unprecocious fish: in female, the ovaries of unprecocious fish stay in 141 stage, and are mainly consisted of oogonias and early oocytes; the ovaries of precocious fish have developed into IIIAV stage, most of the oocytes are in the large growth stage.

性早熟与未早熟大黄鱼性腺的发育有显著不同：未早熟鱼卵巢停留在Ⅰ～Ⅱ期，卵巢内主要由卵原细胞和早期卵母细胞所组成；性早熟大黄鱼卵巢已发育至Ⅲ～Ⅳ，卵巢内大多数卵母细胞处于大生长期中期或后期。

The results of the determinating the activity of the CA in vitro showed that the CA of the water—fed individuals were in activing statics after eclosion. Because of the apperence of the Vg in haemolymph and the deposition of the vitellin in oocytes in the unfed females, it was shown that the CA in such individuals were in activiting statics, too. Again because in the water—fed females which did not lack the feeding action the activity of the CA showed dropping tendency gradually still, it could be said that the activiting of the CA was possibly effected by the nutrition but it was never related to the adult feeding action. In another respect, the brain of the female adult had not significant effect on the activiting CA. The oocytes could depositing vitellin in individuals removed brain tissue on the day of eclosion, which showed that the activting of CA was not concerned with brain.

CA活性的体外测定说明饲水个体的CA同样具有活性，不取食个体血淋巴中Vg的存在以及卵母细胞中卵黄的沉积表明，在不取食的个体中CA同样具有活性，所以CA的活化与成虫期的取食动作无关，与成虫是否取食花蜜也无太多的联系，但是CA活性的维持可能受成虫期营养的影响，如果以卵母细胞发育和CA体积大小作为CA活性的指标，则饲水个体CA的活性在后期受到了影响，说明饲水不能替代取食蜂蜜来维持成虫期CA的活性；成虫期脑对CA的活化无明显作用，羽化当日摘除脑的个体，其卵母细胞仍然可以沉积卵黄，说明CA的活化与脑无关，而是受某种不确定的因子的影响；用抗JH物质—早熟素—Ⅱ以10ug／虫的剂量在颈部点滴处理雌虫，对Vg的发生和卵巢的发育具有一定的迟缓作用，其原因有待于进一步的研究。

These results indicate that TGA treatment can accelerate GVBD in Xenopus oocytes, and GVBD of mouse oocytes at low dose.

在小鼠中卵母细胞中，低剂量的TGA也可加速第1次减数分裂的启动。

The feasibility of maturing denuded buffalo oocytes in vitro was explored in this study, so as to provide a model to investigate the mechanisms of oocytes maturation.

主要探讨无卵丘水牛卵母细胞体外成熟的可行性，以便为研究卵母细胞成熟机理提供模型。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
