胚胎发育

The yolk proteins were collected through the anatomization of the maiden eggs and the eggs in different embryo development stages. The yolk proteins were separated by two-dimensional electrophoresis and followed the image analysis. Over 203 protein spots were found to exist in the yolk protein of silkworm eggs. Some different patterns of yolk protein spots were found in silkworm of various varieties. While, little variation of yolk proteins was detected during different development stages of any silkworm variety.

采用直接解剖蚕卵获取卵黄蛋白，结合蛋白质双向电泳和图像分析，对家蚕处女蛾卵及不同胚胎发育阶段蚕卵的卵黄蛋白质进行了研究，发现家蚕卵黄蛋白有 203 个蛋白质斑点；不同家蚕品种之间卵黄蛋白的组成存在一些差异；同一品种不同发育时期胚胎卵黄蛋白的组成基本保持不变。

LITERATURE EVALUATION: The 32 literatures are about ESCs transcription regulation, the role of FoxD3 for embryonic development and maintaining the pluripotency of ESCs and the function of FoxD3 in other cells （myeloid cells, nervous crest cells and chromatophore cells）.

FoxD3是叉头框（Forkheadbox，Fox）家族中的一个转录调控因子，它对胚胎上胚层及其衍生物的形成和建立多潜能胚胎干细胞系具有重要作用，并与控制胚胎发育和胚胎干细胞多能性的其他转录调控因子有一定的联系。

The first pathogenetic gene identified is α-synuclein, but its phathological mechanism is unknown. In previous study, it's demonstrated that all synuclein isoforms expressed massively in early embryologic development of the central nervous system.

先前有研究指出所有的synuclein异构型在胚胎发育早期即在中枢神经系统被大量表现，显示这一类基因对中枢神经系统的发育可能是很重要的，但是研究synuclein在胚胎早期发育方面的相关研究则较少。

To observ the toxicity of infected mice and establish mice reproductive toxicity model;②To observe the infected BALB/c female mice ovulation quantums and ovum chromosome;③To observe the oestrogenic hormone( FSH, LH, E2 )level of infected BALB/c female mice;④To observe zygote developmental condition before nidation;⑤To observe embryonic development condition of infected mid-gravidity mice to research the reproductive toxicity and development toxicity of toxoplasma gondii to the BALB/c female mice.

目的： 本实验采用弓形虫感染BALB/c雌鼠，①观察染虫雌鼠的毒性反应，建立生殖毒性的小鼠模型；②染虫雌鼠排卵情况及卵母细胞染色体的变化；③染虫雌鼠性激素(FSH、LH、E2)水平的变化；④着床前受精卵的发育情况；⑤孕中期鼠染虫后胚胎的发育情况，探讨弓形虫对雌鼠生殖功能及胚胎发育的毒性作用。

Endoscopic Describing the type of development of a plant embryo in which the inner cell formed by the first division of the zygote develops into the embryo, while the outer cell develops into the suspensor.

内向极性：该名词用来描述植物胚胎发育的一种形式，指受精卵第一次分裂形成的内细胞最后发育为胚胎，外细胞发育为胚柄。

The amniotic fluid and allantoic fluid of chicken embryo have been analyzed and the resonances of most substances in them were assigned by 1-dimention and 2-dimention Nuclear Magnetic Resonance methods. This work could be the basis of quantitative analysis of metabolites and studying the metabolites changing between the amniotic and allantoic fluid during the hatching process. Also, it provided a new way to study the process of embryo developing.

用一维及二维液体高分辨核磁共振(Nuclear Magnetic Resonance，NMR)方法综合分析了鸡胚羊水和尿囊液的成分，对其中的大多数谱峰进行了归属，发现了一些未经报道的小分子代谢物，为研究胚胎发育过程中各个胚囊中体液的交换和小分子的代谢以及进一步对发育过程中代谢物含量变化的定量研究打下了基础，并为研究胚胎发育的过程提供了新的思路。

Spd and Spm evidentlydropped more rapidly in the abortive ovules than those in the normal ones,which indicats that lower contents and more rapid decrease of Spd and Spmduring the embryogenetic process might have a close relationship withembryo abortion.The studies also showed that iow ratios of nn-1and nn-1might hinder embryo development.

败育胚珠中的Spd和Spm含量在胚胎败育期的下降速度显著大于正常胚珠，两者含量低以及在胚珠发育进程中较大的降幅与胚胎败育密切相关。nn-1和nn-1比值低亦不利于胚胎发育。

Thyroglossal duct cysts are the most common cervical cysts and are usually considered to be a benign embryonic malformation where the thyroglossal duct fails to obliterate. Parathyroid cysts are a rare disease and may also result from malformation of the remnants of the third pharyngeal pouch.

甲状舌骨囊肿是最常见的颈部囊肿，一般认为是胚胎发育过程中，甲状舌管没有关闭造成的良性胚胎畸型；副甲状腺囊肿则是一种罕见疾病，可能起因於胚胎发育时第三咽囊的残存物。

The development and maturity of zygotic embryos required a higher level of acyltransferase.Our results showed that ERT and SCL were unique during somatic embryo development,the rest of transcription factors were not remarkable difference with the expression level between two types of embryo development process.

合子胚的发育和成熟要求更高水平的酰基转移酶；除ERT和SCL转录因子是体细胞胚胎发育所特有的，其余转录因子的表达水平在两种类型的胚胎发育过程中没有明显特异之处。

During the first 3 days of sequence culture, SOF and granulosa cell enhanced the development of porcine parthenogenetic embryos and the cleavage rate (P.05) and the number of beyond 4-cell embryos. During the following 3 days. NCSU-23 supplemented with FCS and POEC supported the embryo to morulae/blastocysts.

在序贯培养的前3d，SOF培养基和颗粒细胞对胚胎的发育有促进作用，分裂率(P.05)和突破4细胞阻滞的数目显著增加，在培养的后3d，添加胎牛血清的NCSU-23和输卵管上皮细胞能支持较多胚胎发育到桑囊胚，桑囊胚的发育率为(59.5±3.2)%(P.05)。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
