By the nucellar cells PCD, which were encircling the female gametophyte, the pollen chamber connected with the archegonium chamber for the fertilization in coming.

在胚珠中的雌配子体发育完成、受精过程开始之前，贮粉室与颈卵器室贯通。这一过程是通过雌配子体周围的珠心细胞发生程序性死亡完成的。

Therefore to elicit the functions of the proteins is of great value to delineate the mechanism of spermatogenesis.

因而，揭示这些睾丸生精细胞特异表达蛋白的功能对于阐明精子发生的机理是极其重要的。

Therefore to elicit the functions of these proteins is of great value to delineate the mechanism of spermatogenesis.

因而，揭示生精细胞特异表达蛋白的功能对于阐明精子发生的机理具有极其重要的价值。

Objective The incidence rate of esophageal carcinoma in ChangZhi area located in the TaiHang Mountain, is very higher. The character of general demology and environmental factors were observed and analyzed to explore the susceptibility to esophageal carcinoma in cases and controls with different cytochromeP4501AlExon7 MSP1 genotypes. This could contribute to finding the cause of disease and suggesting the level of predicting the esophageal carcinoma susceptibility.

目的 长治地处太行山区，食管癌死亡率高达80～/10万，调查该地区一般人口学特征及环境因素，探讨细胞色素P4501A1Exon7、MSP1A、B、C三种基因型与食管癌遗传易感性的关系，结合遗传因素与环境因素进行分析，将有利于揭示食管癌发生的病因，提示对肿瘤易感者预测的水平。

The concentration of DOX in tumor and the apoptotic rate in cancer cell were all higher in DOX plus CWQ group than that in other groups.

结果 阿霉素和肠胃清单独给药均不能抑制肿瘤组织的生长，阿霉素与肠胃清联合能显著减少肿瘤组织的重量，增加肿瘤组织内的阿霉素浓度，诱导肿瘤细胞发生凋亡。

One way by which IKK- controls skeletal and craniofacial morphogenesis is by repressing expression of fibroblast growth factor family members, such as FGF8, whose expression is specifically elevated in the limb bud ectoderm of IKK--deficient mice.

IKK控制骨骼和颅面形态发生的一个途径是抑制成纤维细胞生长因子家族成员如FGF8的表达，后者的表达在IKK缺失小鼠肢芽外胚层中特异升高。

In addition, the mitochondria showed no signs of swelling and the nuclear membrane remains intact. Multiple membrane-bound apoptotic bodies and engulfment of cell debris and corpses by phagocytes were observed at 24h, while extensive cell loss appeared at 48h. These results demonstrated the occurrence of high level of apoptosis by 24h postdosing.

相应的超薄切片在电子显微镜下得到结果与光镜下一致，24h前线粒体形态结构无明显变化，主要有染色质浓缩、边集及分割，以及内质网空泡化和凋亡小体的形成；24h后可观察到线粒体的肿胀和扩张，细胞发生崩解和死亡。

The chemico-biological process on the interface established by cells and solid surface is a fundamental chemical problem confronted by medical, environmental, agricultural sciences as well as biotechnology.

在细胞和固体表面建立的生物界面上发生的化学－生物学过程是一个医学、环境、农业和生物技术共同面对的问题。

Age-related hearing loss occurs because the hair cells that line the sound pathway in the ear begin to die.

年龄相关性听力损失的发生是因为毛细胞线的声音通路在耳朵开始死亡。

The DNA rearrangements that occur in cancerous cells are unique, which makes it easier for scientists to detect them.

发生在癌性细胞中的 DNA 重排是独特的，这使其更容易让科学家们发现它们。

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
