Methods The active homograft bioprosthetic pediculated conduit preserved in liquid nitrogen were selected as experimental material and decellularized by sodium dodecyl sulplate containing low osmotic Tris buffer.

方法选取经液氮保存、具有活性的同种生物带瓣管道作为实验材料，用含十二烷基硫酸钠的Tris低渗缓冲液脱去同种带瓣管道存在的细胞；固定剂固定后，分别行HE染色、胶原纤维和弹力纤维染色的光镜和扫描电镜观察、摄片。

Cerevisiae GAPp, suggesting that H. polymorpha △9-fatty acid desaturase was compatible with desaturation system of S. cerevisiae whereas the promoter of H-OLE1 gene had no activity in heterologous cells.

说明H-OLE1基因编码△9-脂肪酸去饱和酶，多形汉逊氏酵母的△9-脂肪酸去饱和酶和酿酒酵母的脂肪酸脱饱和系统相亲和，而H-OLE1基因的启动子在异源细胞中没有活性。

Sample preparations such as prevention of protein degradation, removement of cell element, concentration, degreasement, desaltation, and albumin depletion were taken to meet the demands of two-dimensional polyacrylamide gel electrophoresis.

用防止腹水蛋白质降解、去细胞成分、浓缩、去脂、脱盐及去干扰大的白蛋白等腹水的前期处理以满足双向凝胶电泳的条件。

N-(2-hydroxyethyl)-glucamine was dehydrogenated to 6-(2-droxyethyl) amino-6-deoxy-a-L-sorbofiuanose the key intermediate of miglitol by the resting cells of Gluconobater oxydans Gouv2007 through aeration. 6-(2-Droxyethyl) amino-6-deoxy-a-L-sorbofiuanose was hydrogenated catalyticlly to miglitol. In the transformation of N-(2-hydroxyethyl)-glucamine to miglitol, the transformation rate was 77.3%.

氧化葡萄糖酸杆菌Gouv2007的静息细胞在通气下氧化N-羟乙基葡糖胺脱氢生成米格列醇的前体物质6-脱氧－6-羟乙基氨基－α-L-呋喃山梨糖，再催化加氢生成米格列醇，对从N-羟乙基葡糖胺生成米格列醇的底物转化率为77.3%。

Objective:To explore the application of the basic fibroblast growth factor combined partially demineralized allogenic bone in mandibular defects, and to study the effects of bFGF in bone formation as well as the selection of its carrier.

目的：探讨bFGF(basic fibroblast growth factor ，碱性成纤维细胞生长因子)复合部分脱矿冻干辐照异体骨在修复下颌骨缺损中的应用，研究bFGF在骨缺损修复中的成骨作用机制及其适宜载体的选择。

Histopathological changes were found on the above-said organs but RNA content in liver increased.

结果表明，甲状腺机能低下阳虚兔模型的上述器官，在形态结构上均有不同程度的病损改变；其肝细胞琥珀酸脱氢酶等酶活性的变化不明显，而RNA含量较高。

The Michigan study, which began in late 2004, indicates cells from normal and cancerous breast tissue that contain high levels of the enzyme group aldehyde dehydrogenase acted like stem cells.

该研究显示，正常乳腺组织和癌变乳腺组织的细胞中均含有大量的乙醛脱氢酶酶组，它们所起的作用就如同干细胞。

The results showed that the partially folded chicken heart apocytochrome c has a highly dynamic hydrophobic core and also tends to aggregate, which is consistent with its folding tendency.

结果表明，部分折叠的鸡心脱血红素细胞色素c分子获得了一种高度动态的结构，形成了动态的疏水核心；同时，它也具有较强的凝集倾向。

Based on our results, we deduce that DsbE protein may maintain the thiols of apocytochrome c in a reduced form, which is beneficial to heme insertion.

基于以上的实验结果，我们推测：DsbE可以维持脱辅基细胞色素c的巯基处于还原态，以利于卟啉的插入。

MTT assay is a convenient method to estimate the number of viable cells, which de- pends on the reduction of tetrazolium salt, MTT, to form a blue formanzan product by living cells.

MTT测定法是根据线粒体脱氢酶催化MTT形成蓝色甲■的多少来检测活细胞数和功能状态的，但原始方法中存在着一些问题，如敏感性偏低、有机溶剂产生蛋白质沉淀以及产物的溶解度偏低等。

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.

交际能力和语法的关系应该是目标与途径的关系。
