Gilts were slaughtered on day 12, 25 and 35 of pregnancy, and serum, uterine flushings, embryos and endometria were collected. ELISA was adopted to determine the progesterone concentration in serum and uterine flushings, and RT-PCR was adopted to determine the genes expression in embryos and endometria.

母猪配种后随机分到3个组，按2.0倍、1.2倍和0.6倍维持需要供给饲粮（分别为采食高、中、低水平），妊娠12、25和35d屠宰母猪，收集血清、子宫液和胚胎、子宫组织，运用ELISA测定血清和子宫液中孕酮浓度，用RT-PCR测定目的基因在胚胎和子宫内膜中的表达。

Protection for Foetuses: Natural antioxidants such as apple polyphenol and Vitamin E protect against aggression of excessive radicals and enhance protection of the foetuses

胚胎保护：添加苹果多酚和维生素 E 等天然抗氧化物质，抵御自由基的侵害，加强对胚胎的保护

The sex cells are called gametes and when they join ,they form an embryo, which is a very young organism

性细胞被称作结合体，当他们结合时就形成了胚胎，胚胎是生物体的初期阶段。

The Embryos Bill sets limits on the use of gametes and embryos .

胚胎法案》对于配子和胚胎的使用进行了限制。

After γ ray treatment, two kinds of cells were incubated on 6-well gelatin-coated plate with density of 2.5×104/cm3. hESCs were cultured on HAFi or MEF feeder cells containing β-mercaptoethanol DMEM/F12 and basic fibroblast growth factor.

取人胚胎干细胞，分别接种在小鼠胚胎成纤维细胞或永生化人成纤维细胞饲养层上，加入含β-巯基乙醇的DMEM/F12培养基，使用前添加碱性成纤维细胞生长因子。

ZNF268 gene encodes a typical KRAB-containing zinc finger protein, which has an amino-terminal KRAB domain and 24 carboxyl-terminal C2H2 zinc finger motifs. There is evidence that ZNF268 is expressed in human early embryos, and that it played a role in the development of human fetal liver.

ZNF268是一个典型的KRAB类锌指基因，含有24个C2H2型锌指基序和一个KRAB功能域，它在人胚胎发育早期表达，并与胚胎肝脏的发育相关。

In order to investigate the effect of IGF2 on the regulation of development of prenatal skeletal muscle in pigs, the SYBR-Green real-time PCR method was established and used for expression analysis of IGF2 in the prenatal skeletal muscles from Tongcheng and Landrace pigs at 33, 65 and 90 days post coitus.

为了研究IGF2对猪胚胎骨骼肌生长发育的调控，本文建立猪IGF2基因的SYBR-Green荧光定量PCR方法，并利用此方法分析该基因在通城猪和长白猪妊娠33天、65天和90天胚胎骨骼肌中的表达规律。

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。
