胚胎

In case 6, the heart looks "inverted" compared to normal (Figure 8). This phenomenon is called dextrocardia, and it results from a looping anomaly during embryologic development.

病例6中的心脏与正常相比看上去就像"反转"了一样（图8），这称作右位心，是由于胚胎发育过程中的心脏成环异常导致。

Recent studies showed small interfering RNAs generated by Dicer from longer dsRNA specifically suppressed expression of genes in somatic and embryo cells.

研究表明，Dicer断裂dsRNA产生的小干涉RNA可以抑制哺乳动物体细胞和胚胎中的基因的表达。

The most anterior of the three primary regions of the embryonic brain from which the telencephalon and diencephalon develop.

前脑大脑胚胎三个主要区域中最靠前的一个，端脑与间脑从这里发育

The activity of Cre recombinase is predominantly detected in the midbrain, diencephalon and olfactory bulb in the SCC4.4-iCre transgenic brain. However, it only can be observed in the caudal part of the midbrain in the SCC2.7-iCre brains. The results suggest that CYP11A1 gene expression could be differentially regulated in different regions of the brain.

结果发现，4.4 kb与2.7 kb之CYP11A1启动子皆可使Cre重组酶表现於胚胎脑部，前者主要表现在中脑、间脑及嗅球，后者仅主要表现在中脑尾端，说明了CYP11A1在不同脑区表现所需的元素有所不同，可能有不同的调控机制。

In order to explore the methods of evaluating of environmental hormone,this study investigated the effects of diethylstilbestrol on the development of the sexual organ of chicken embryos.

为探讨环境激素的评价方法，研究了己烯雌酚对鸡胚胎性器官发育的影响。

To sum up, we first conclude that we can isolate mesenchymal stem cells from human fetal articular cartilage and they can be induced to differentiae into several cells under appropriate induction conditions. Anymore, they have their original tissue speciality. Therefore, we first report that mesenchymal stem cells of articular cartilage origin are superior to mesenchymal stem cells of bone marrow origin as seeding cells of cartilage tissue engineering and we provide a kind of new seeding cells of cartilage tissue engineering for the future clinic application.

综上所述，我们首次报道不仅可从人胚胎的关节软骨中获得间充质干细胞，而且软骨来源的间充质干细胞除具有骨髓来源的间充质干细胞的多向分化能力外，还具有其来源的软骨组织特异性，那么，其作为软骨组织工程的种子细胞要优于骨髓来源的间充质干细胞，从而首次提出了一种新型的软骨组织工程的种子细胞，对于未来的软骨组织工程的临床应用提供理论依据。

It is concluded that many genes both known and unknown are differentially expressed in human embryonic aorta-gonad-mesonephros-derived stromal cells.

筛选agm区基质细胞中差异表达的基因为进一步研究胚胎造血发育的分化调控的分子机理提供了必要的理论基础。

This process is important to the evolution of a species and to embryonic growth and differentiation.

这个过程对一个种类的演化和对胚胎的发展和区别是重要的。

In contrast, there is evidence that the embryos of five GlyR is composed of α2 subunit with the dimer.

相反，有证据表明胚胎GlyR是由五个α2亚单位组成的同聚体。

In several species there is sexual dimorphism in the embryogenesis of the excretory duct system.

在某些物种中，分泌管道系统的胚胎形成期间会出现雌雄二型性。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
