AIM To detect HBV protein influence on the cleavage activity of ribozyme.

目的 探讨乙型肝炎病毒蛋白对核酶剪切作用的影响。

Before treatment,there are abundant microvtlli on the cell surface,many filoplodia on the cell rim,few of endoplasmic reticulums , Golgi complexes and mitochondrions with abnormal structure and lots of free ribosomes in the cytoplasm. The shape of nucleus is irregular with high nuclear-cytoplasmic ratio, many dark pellets of heteromatin and a few of nucleoluses in which there ar...

经1.5×10~2g/L地塞米松处理后，细胞表面微绒毛和丝状伪足显著减少或消失，出现皱褶状和小泡状结构；细胞核形规则，核质比值减小，异染色质团块减少，核仁数目减少、结构致密；细胞质中粗糙型内质网、高尔基体、线粒体数量增多，形态结构典型，游离核糖体减少，这些变化说明地塞米松改变了MGc80-3细胞的超微结构特征，具有明显的诱导分化作用。

Construction of heavy chain transgenic mice and genome type analysis Linearized transgene plasmids were microinjected into pronuclei of zygotes from CBA×C57BL/6 mice, and transplamted into oviduct of pseudo-pregnant mice.

二、抗体重链转基因小鼠建立及基因型分析将线性化的质粒显微注射入CBA×C57BL/6小鼠的受精卵细胞的雄前核内，然后导入假孕雌鼠的输卵管。

The construction of A83 eukarotic expression vector will play an important pole in researching the effect on HBeAg expression and disease mechanism when A83 mutation in HBV signal peptide reg

HBV A83点突变真核表达载体的构建为体外研究该点突变对HBeAg表达的影响以及HBeAg阴性的乙型肝炎病毒感染的致病机理奠定基础。

The RER, which is studded with polysomes, also seems to be the source of the nuclear envelope after a cell divides.

糙面型内质网，镶嵌在多聚核糖体中，也可能是细胞分裂后核膜的来源。

It was indicated that the haze of PP was decreased drastically and the glosses and mechanical properties of PP were improved by dehydroabietate-based nucleators.

结果表明，脱氢枞酸型成核剂可以大幅度降低聚丙烯的雾度，提高光泽度，改善力学性能。

DSC measurements indicate that the crystallizing temperature and the melting temperature of the three-arm star-shaped polyethylene glycol were different from those of the corresponding linear PEG because the existing of TMP-SK3 altered its crystallizing velocity and the perfect degree of crystals.

DSC测试结果表明，与线型聚乙二醇相比，三臂星型聚乙二醇由于TMP-SK3核的存在，不仅影响聚乙二醇的结晶速度，同时也影响结晶的完善程度，导致其结晶温度和结晶熔融温度发生变化。

For the nuclear safety-related parallel sluice valve,vibration performance computation and analysis is obligatory during its safety evaluation.

同时，以PZ62Y-50/150型核岛平行式双闸板闸阀为例，讨论了采用三维有限元分析软件进行核安全级阀门振动特性分析的基本思想和过程。

This paper presents three IP cores in detail, which arecharacter LCD controller, Timer/Counter and DMA controller. All those tree IP cores interfacesare WISHBONE compilable.

本文完成了遵循WISHBONE总线标准的字符型LCD控制器、定时／计数器、DMA控制器3个IP软核的设计。

Objective To construct the eukaryotic expression vector for pathogenic gene MYOC of primary open angle glaucoma and express in COS-7 cells.

目的 构建原发性开角型青光眼致病基因MYOC的真核表达质粒，并在COS-7细胞中表达MYOC蛋白。

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。
