We conclude that the urinary bladder ECM but not the small intestine- or lier-deried ECM contains a surface with composition and morphology consistent with that of an intact basement membrane complex, that the basement membrane complex can surie processing, and that the basement membrane structure can modulate in itro cell growth patterns.

我们得到的结论是，膀胱来源的ECM含有一层组成和形貌都与完整基底膜复合物一致的表面结构，而小肠和肝来源的ECM没有这层结构；基底膜复合物结构能够在ECM整个加工过程中保证完整而且能调节体外细胞生长模式。文献摘要申领

On the top of the beauty in histology is the combination of the structure and its function.

从人体细胞形态、切片的色彩、组织结构的形态以及层次比例等方面展示了显微镜下的人体组织结构的形态美，人体结构与功能的和谐构成的生命之美是人体组织学美的顶峰。

In the current study, a series of cationic α-helical peptides of 20 a.a. were designed and synthesized based on four structural parameters, including charge, polar angle, hydrophobicity, and hydrophobic moment. Several methods were performed to describe the influence of these parameters on the antimicrobial and hemolytic activity, and on the permeabilizing effect on model membranes. The potential of these parameters to increase the antibacterial activity and to improve the prokaryotic selectivity is assessed.

本实验利用自行设计合成的人工抗菌胜肽当模型，固定长度为 20 个胺基酸，改变其电荷、极性角度、疏水性及疏水性矩等四种结构特性，并利用其对各种不同病原菌之抗菌活性及对兔子红血球细胞的溶血活性来研究其结构特性的改变对其抗菌活性、选择性及微脂体膜的渗透性之影响，以期望改变结构参数能增加抗菌活性及对原核的选择性。

Currently activities involve (1) Investigation of dye-DNA interaction by using spectroscopic methods to probe the binding sites between chromophore and DNA and to identify various DNA conformational structures, particularly the telomeric DNA;(2) Investigation of the structure-activity correlation of anti-telomerase agents;(3) Design and synthesis new compounds for antitumor agents and fluorescence biomarkers;(4) Monitoring the folding and unfolding of quadruplex structure, tracing the pathway of drug delivery and probing drug-target interaction by using single molecule microscopy and spectroscopy.

目前 的研究重点分别是(1)利用光谱方法探讨探针分子与DNA的交互作用，特别是作用位置与结构变化；(2)研究抗端粒酵素作用分子之结构与生物活性之关系；(3)设计及合成抗肿瘤药剂或萤光生物标记；(4)建立单分子萤光光谱与影像技术，研究 DNA的多变型结构之变化机制，监测药物输送的路径过程及其在细胞中与标的物的作用。

The epithelial component in this Wilms tumor consists of primitie cuboidal cells forming tubular structures and rosettes.

肿瘤含有原始结构的立方上皮细胞，形成原始管状结构和玫瑰花结样结构。

After treated in 4% paraformaldehyde,we applied Hematoxylin-Eosin and Nissl staining to exhibit the structure of the retinae and ganglion cells respectively,and also we used immunohistochemical ABC method to display the distribution of GFAP-immunoreactive cells that were specifically classified as the astrocytes.

E 染色以显示视网膜结构，Nissl染色显示神经节细胞，免疫组织化学ABC法染色以显示星形胶质细胞特征性标志物胶质纤维酸性蛋白的阳性反应细胞的分布。

Complicated than procaryotes. These cells, exemplified by the yeast in Figure 4.1-3, have a membrane surrounding the cell which is similar in structure to the procaryote membrane.

真核细胞，具有真正的细胞核，其结构要比原核生物复杂的多，以图4.1-3中所示的酵母菌为例，和原核细胞一样真核细胞也具有一层细胞膜。

EM of a "typical" cell, showing the organelles common to almost all cells of the body.

显示了一个&典型&的细胞电镜图，有一般细胞共有的细胞器结构。

Theoretical classes focus on the conceptions involving cell biology, the ultrastructures, chemical composition and function of organelles in cell, the mechanisms of biochemical action and the research methods as well.

理论课教学内容重点讲授细胞生物学有关的基本概念、细胞内各种机构及细胞器的亚显微结构、化学组成和功能作用，介绍重要生化活动的分子机制及本学科的主要研究方法。

In most species they are composed of roughly equal amounts of protein and ribosomal RNA , the ribosome consists of two unequally sized rounded subunits arranged on top of each other like a cottage loaf, eukaryotic cells have larger ribosomes than prokaryotic cells but the ribosomes in mitochondria and chloroplasts are about the same size as prokaryotic ribosomes.

在大多数的物种中，蛋白质的量和 rRNA 量是大体相等的。核糖体包括两个大小不同的亚单位，上部结合形成小屋状结构。真核生物细胞中的核糖体要比原核细胞的核糖体大，但是线粒体和叶绿体中的核糖体与原核细胞的核糖体大小相当。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
