自制的胚胎冷冻液含有三种不同的冷冻保护剂(包括渗透性和非渗透性保护剂)，冷冻胚胎解冻后可用率在95％左右，比常用的DMSO冷冻液更适宜于这三种细胞的冷冻保存。

The mitotic error rate in cleavage stage embryos was proven to be higher than the meiotic aneuploidy rate and as a consequence, the genome of a single blastomere is not representative for the genome of the other cells of the embryo.

在卵裂期胚胎这种有丝分裂的错误率被证明是高于减数分裂的非整倍体错误率，因此，单个卵裂球的基因不能代表其他胚胎细胞的基因组。

In humans the cornea is clear, but it is more a thin, gelatinous layer of proteins and sugars than true cellular tissue.

人类的角膜是透明的，但它只是薄薄一层由蛋白质与醣类构成的胶状结构，而非细胞构成的组织。

Objective: With umbilic blood from the mature newborns, to screen CpG-ODN, which can markly boost up the immunity response, from some designed CpG-ODNs; to compare the effect of CpG-ODN on the lymphopoiesis of umbilic blood from the premature, mature newborns and the peripheral blood from the adults; to observe the infulence of CpG-ODN on the immune function of the pregnant mices and their newborns, the immune-inhibited and aged mices.

目的：设计含非甲基化胞嘧啶和鸟嘌呤的寡聚脱氧核糖核苷酸，以期用足月新生儿脐血筛选出具有较强免疫增强作用的CpG-ODN；比较CpG-ODN对新生儿脐血和成人外周血单个核细胞的增殖效应；观察CpG-ODN对孕鼠及其新生鼠、免疫抑制鼠和老年鼠体液免疫功能的影响。

EMSA results show that the binding patterns between the core DNA sequences of DNase Ⅰ supersensitive sites (HS2, HS3 and HS4) in LCR and nuclear matrix proteins isolated from Hu-induced and uninduced-HEL cells are quite different.

运用凝胶电泳阻抑法揭示了用羟基脲诱导与非诱导的HEL细胞内，与LCR中的DNaseⅠ超敏感点（HS2，HS3和HS4）核心DNA序列结合的核基质蛋白发生了显著的变化。

A multicellular organism of the kingdom Animalia, differing from plants in certain typical characteristics such as capacity for locomotion, nonphotosynthetic metabolism, pronounced response to stimuli, restricted growth, and fixed bodily structure.

动物动物界中的多细胞生物，某些典型特征与植物不同，如有运动能力，能进行非光合作用的新陈代谢，能对刺激产生有声反应，有限制的生长和固定的身体结构

A systematic literature search of PubMed, MEDLINE, BIOSIS, EMBASE, and Cochrane EBM databases during the period of 1990–2007 was made, objective being the randomised controlled trials in patients with AMI who underwent primary percutaneous coronary intervention and received intracoronary BMSC transfer, and were followed up for at least 3 months.

目前，冠脉内自体骨髓干细胞移植在AMI的临床应用仍存在较大争议。研究者检索了1990年至2007年间PubMed、MEDLINE、BIOSIS、EMBASE和Cochrane EBM等数据库收录的文献，根据以下标准纳入临床研究：以AMI症状出现24小时内接受PCI治疗者为研究对象；试验设计体现随机对照原则；移植细胞种类为非动员的自体骨髓干细胞；具有3个月以上的随访资料。

Human leukocyte antigen-G is a neoclassical human leukocyte class Ⅰ b antigen which was observed to be restrictively expressed by the fetal-maternal inter-fate on the extravillous cytotrophoblast.

人类白细胞抗原－G(human leukocyte antigen-G， HLA-G)属于非经典的HLA-Ⅰ类抗原分子，早期的研究发现HLA-G的表达仅局限于母胎界面的绒毛外细胞滋养层。

Histomorphometric studies were done to measure the following indexes: the IOD values of pulmonary, skeletal muscular and pleural small vascular walls from staining of AT1 and AT2 receptors, the pulmonary vascular density, muscularization of the nonmuscular vessels, percent wall thickness and proliferation of pulmonary small vascular walls.

结果：先心病患儿肺小血管壁AT1、AT2受体染色的IOD值均高于对照组(P=0.000)；先心病患儿骨骼肌和胸膜小血管壁AT1、AT2受体染色的IOD值均高于肺小血管(P＜0.05)；先心病患儿肺小血管壁AT1受体染色的IOD值与肺血管密度、非肌性肺血管肌化程度、肺小血管壁厚百分比和肺小血管壁细胞的增殖度相关(r分别为-0.783、0.742、0.521、0.657)，AT2受体仅与肺血管密度和血管壁厚百分比相关(r分别为-0.487、0.516)。

However, a steady input of evidence for the transcription-independent function of p53 in apoptosis has been accumulating recently. Although a detailed mechanism has not yet been determined, recent data have revealed that upon an apoptotic stimulus, p53 translocates into mitochondria to interact directly with Bcl-2 or Bcl-xL to displace and activate proapoptotic Bax signaling.

但是，还有研究证明p53也通过转录非依赖的形式来调节细胞凋亡，尽管这个作用的机制还没有被详细的阐明，但是最近的研究报道说明了，p53可以直接转移定位到线粒体上，与Bcl-2或者Bcl-xl结合后，从而使Bax游离下来并活化。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
