The results showed that autote traploid rice might be effectively improved by ion beam bio-technique, from which the new germplasm with hereditable twin-embryo seedling could be selected.

结果表明，利用离子注入技术可以对同源四倍体水稻进行有效地改良，由此可以获得具有遗传变异特点的新种质，其双胚苗特性随着自交世代的推进而得到保持。

It dedicates to publishing herpetological monographs about the studies of the biology of amphibians and reptiles, including new species, reproduction, genetics, embryo growth, coevolution, speciation, developmental stability analysis and experimental evaluation etc.

该杂志致力于出版关于两栖动物与爬虫类动物生物学研究的爬行动物类专论，包括新的种属、繁殖、遗传学、胚胎生长、协同进化、物种形成、发育稳定性分析以及实验评价等等。

While in the heterozygotic ZW embryo, expression of estrogen receptor, steroidogenic factor-1 and P450 aromatase might stimulate ovarian formation.

在异型配子 ZW 胚胎中，雌激素受体、类固醇生成因子-1 和 P450 芳香化酶基因的表达可刺激卵巢的形成。

Onchosphere; hexacanth embryo; six-hooked larva

The functional target of the microRNA appears to be the HOXD10 gene, one of the Hox gene family involved in directing embryo development.

微RNA的功能目标似乎是HoxD10基因，它是参与引导胚胎发育的Hox基因家族的一个成员。

The project leader, Dr Richard Morgan, explains 'HOX genes are important in determining the identity of cells and tissues in the early embryo, but they are also expressed by cancer cells.

该项计划领导者Richard Morgan博士说'HOX基因在胚胎时期对决定细胞和组织的性质很重要，但它们在癌细胞也能表达。

Hyperglycemic is toxic to early embryo development. These findings hint that hyperglycemia may cause higher rates of congenital abnormality and early pregnancy loss in patients with diabetes.

高血糖对早期胚胎的发育具有毒性作用，提示高糖可能导致妊娠合并糖尿病患者的流产和胎儿畸形率升高。

These experiments demonstrated that hyperglycemic conditions in vitro can inhibit the growth and development of the embryo cells resulting in the down-regulated expression of igf-1, and IGF-1 could inhibit the apoptosis of blastocyst and be benefit for the growth of blastocyst.

因此，高血糖能抑制胚泡细胞的生长发育，导致igf-1的表达下调，而IGF-1能抑制胚泡细胞的凋亡，有利于胚泡细胞的生长发育国。

At the one-cell stage, each embryo was injected with gradient doses of 2-8ng MO. The control morpholino, was purchased from Gene-Tools.To test the knockdown effectiveness of the morpholino, the tbx2-EGFP (enhanced green fluorescent protein) construct was generated. And coinjection of morpholino with mRNA tests its specificity of the morpholino. Overexpression of tbx2 via mRNA microinjection helps us understand gaining function of tbx2. Results The tbx2-EGFP construct tests the knockdown effectiveness of the morpholino. Zebrafish embryos lacking tbx2 function have defects in cardiac contractility, rhythm and morphology in a dose-dependent manner. The embryos with c-MO are normal in development. Coinjection of morpholino with mRNA rescue the phenotype of tbx2 knocking down. The phenotypes include pericardial edema, hypogenetic ventricle, dilation of atria, arrhythmia, bradycardia, asystole, abnormal atrioventricular canal, aberrant valve and blood regurgitation.

结果荧光蛋白融合标记实验验证了tbx2-MO可以很好得阻抑斑马鱼胚胎tbx2的表达，tbx2-MO组胚胎在心脏收缩性、节律和形态学发生上出现了异常，心脏畸形随着注射剂量的增加而出现比较一致的表型，而c-MO组胚胎没有出现明显的畸形；tbx2-mRNA和tbx2-MO的共注射减少了tbx2-MO胚胎心脏畸形的发生率及减轻了心脏畸形的程度，验证了所设计合成的tbx2-MO对tbx2基因的抑制作用具有特异性；tbx2-MO组胚胎心脏缺陷包括心室发育不良、心房扩张、房室管和瓣膜异常以及心率缓慢、心律不齐、心脏停搏、血液返流等，并根据心脏发育异常的程度分为轻、中、重度畸形组tbx2-mRNA基因过表达胚胎没有见到心腔的形成。

With the great progress in embryo engineering during the past decade, the maturing oocytes with high qualities and quantities are increasedly required.

然而由于目前对卵泡发生和发育的调节机制仍知之甚少，因此大大制约了利用卵泡体外培养和体外成熟技术生产成熟卵母细胞的成功率。

Recall that, in the Kolmogorov axiomatization, measurable sets are the sets which have a probability or, in other words, the sets corresponding to yes/no questions that have a probabilistic answer.

延期开工的Kolmogorov宣布要衡量所有套职能有限许多坐标限制在于衡量子寅。换句话说，如果是/否的问题回答f可看的价值观念在许多最有限坐标，然后它有一个概率的答案。

The experimental results showed that the algorithm can filter singular points and remain fixity of the target edge.

实验表明：基于模糊理论的图像智能滤波方法比常规图像滤波方法运算量小，它既能去除奇异点，又能保持图像中目标的边缘不变性，具有很好的滤波效果。
