The results indicated: 1 .There is obvious difference between the gonads of precocious and unprecocious fish: in female, the ovaries of unprecocious fish stay in 141 stage, and are mainly consisted of oogonias and early oocytes; the ovaries of precocious fish have developed into IIIAV stage, most of the oocytes are in the large growth stage.

性早熟与未早熟大黄鱼性腺的发育有显著不同：未早熟鱼卵巢停留在Ⅰ～Ⅱ期，卵巢内主要由卵原细胞和早期卵母细胞所组成；性早熟大黄鱼卵巢已发育至Ⅲ～Ⅳ，卵巢内大多数卵母细胞处于大生长期中期或后期。

However, fully consideration of special structure and physiological function of CRP is critical to investigate whether CRP provide protect effect or pathogenic effect in the progression of atherosclerosis. CRP is a member of pentrxins family, which consists of five identical, noncovalently associated 23-kDa protomers arranged symmetrically around a central pore with a 102 A external diameter. Each protomer has a recognition face with a phosphocholine binding site consisting of two coordinated calcium ions adjacent to a hydrophobic pocket. The opposite face of the pentamer is the effector face, where complement Clq binds and Fc receptors are presumed to bind. A cleft extends from the center of the protomer to the central pore of the pentamer. Both faces ofpentamer form a special bi-phase structure: one face is the ligand recognition phase, which can recognize apoptosis cells and enzyme modified low density lipoprotein in which PCh is exposed.

CRP是一种五聚体蛋白，外径为102 A，由5个相同的单体以非共价键结合，形成双面的环形结构，每个单体的配体识别位点或受体结合位点分别位于五聚体两个平面上，分别组成配体识别相和效应器相，从而构成特殊的二相性结构：一面为配体识别相，含有磷酸胆碱(phosphorycholine，PCh)结合位点，能够使CRP识别在病理条件下暴露出PCh的凋亡细胞、酶修饰低密度脂蛋白(enzyme modified low density lipoprotein，E-LDL)等。E-LDL是天然低密度脂蛋白(native Low density lipoprotein，N-LDL)在多种蛋白酶，如胰蛋白酶、神经氨酸酶、胆固醇酯酶等作用下的代谢产物，其主要特点是结构发生改变(N-LDL大小均匀，平均直径250±30 A，E-LDL大小差异极大，直径为100-2000 A)，暴露磷酸胆碱位点，能够被CRP识别；另一面为效应器相，能够与巨噬细胞、单核细胞表面受体FcγRⅡa结合，介导巨噬细胞、单核细胞识别及吞噬凋亡、坏死细胞作用。

Also, fiber serves as an excellent single-celled model for studying fundamental biological proc esses, such as cell elongation and differentiation Plant primary cell walls consist of mainly pectin, hemicellulose and cellulose, and are deposited during the cell expansion phase.

同时，棉纤维细胞也是研究细胞伸长、分化和细胞壁合成等重要生物学现象的理想系统。植物初生细胞壁主要由果胶、半纤维素和纤维素等多糖组成。

The human immunodeficiency virus is made of genetic material, RNA, which invades cells. The virus essentially hijacks the cell, and uses its machinery to multiply and survive.

人类免疫缺陷病毒是由遗传物质RNA组成，RNA病毒入侵细胞后，从根本上劫持细胞，把细胞当做复制的机器和生存的场所。

The OXPHOS electron transfer chain (mitochondrial respiration chain) is located on the inner membrane of mitochondrion and comprising of four large trans-membrane protein complexes (mitochondrial respiratory Complex I, II, III and IV) as well as ubiquinone between Complex I/II and III and cytochrome c between Complex III and IV.

摘 要：线粒体作为真核细胞的重要&能量工厂&，是细胞进行呼吸作用的场所，呼吸作用包括柠檬酸循环和氧化磷酸化两个过程，其中氧化磷酸化过程的电子传递链位于线粒体内膜上，由四个相对分子质量很大的跨膜蛋白复合体(I、II、III、和IV)、介于I/II 与III之间的泛醌以及介于III 与IV之间的细胞色素c共同组成。

The cell and cell nucleus are taken to be concentric spheroids.

细胞由细胞膜、细胞质和细胞核组成，细胞核位于细胞的中央，周围被细胞质包围。

Varying degrees of thickening in gallbladder wall and straw-colored or brown-yellow plaque or node in cross-section can be seen, some with pedicle swelling like polypus, normal structure of gallbladder wall is found to have bean damadged microscopically, replaced by characteristic yellow granulomatous structure, consisting of plenty of foamy cells, acute and chronic inflammatory cells, fibroblasts, foreign-body giant cells and Touton cells.

大体观察胆囊壁不同程度增厚，切面常见淡黄色大小不等的结节或斑块，有的有蒂呈息肉样隆起。镜下见胆囊壁的正常结构受到破坏，代之以特征性黄色肉芽肿性结构，由大量泡沫样细胞、急慢性炎细胞、纤维母细胞、异物巨细胞及Touton细胞等组成。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
