In this study, after 80 day administration with aminoguanidine, AGE in diabetic rats' bone collagen was not obviously reduced.

AGE在肾脏中的积累增多，一方面影响1-α羟化酶的分泌，另一方面直接修饰1-α羟化酶，使其活性降低。1，25-〓生成减少，作为1，25-〓的&促激素&PTH代偿性分泌增加。

Histone acetyltransferases and deacetylases function antagonistically to control histone acetylation.

组蛋白的乙酰化在调节染色体结构和功能中起着重要的作用，而这种调节受组蛋白乙酰化酶和去乙酰化酶的共同调节。

The composition of amino acid of the enzyme was also analyzed,which indicated that the contents of asparaginic acid, serine, glutamic acid, glycin, alanine are the most, lysine, histidine also have high contents and there are a few praline, tryptophan.

最后，对此酶的氨基酸成分进行了分析，结果表明，此酶分子中天冬氨酸、丝氨酸、谷氨酸、甘氨酸、丙氨酸含量高，两种碱性氨基酸精氨酸、赖氨酸及组氨酸的含量也比较高，而脯氨酸、色氨酸的含量相对较低。

After cultivating in liquid medium for 5 days, an extra cellularβ-mannanase from Athelia rolfsii strain CBS191.62 was purified 15.1-fold toelectrophoretic homogeneity by ammonium sulfate precipitation, DEAESepharose Fast Flow chromatography, Hydroxylapatite chromatography andrefrigeration crystal.

产β-甘露聚糖酶的Athelia rolfsii菌株CBS 191.62，发酵培养5d，发酵液离心去菌体，上清经硫酸铵沉淀，琼脂糖凝胶层析、羟基磷灰石层析和冷冻干燥结晶等步骤，β-甘露聚糖酶的比活提高了15.1倍，获得凝胶电泳均一的蛋白样品。

In addition, the separation of products and recovery of enzymes are very easy in this kind of bioreaction systems, which implies the potential possibility of industrial application.

逆胶束中水的这些特殊性质，正是逆胶束增溶酶的催化性能不同于普通水相酶的内在依据。

The effect of guanidine hydrochloride concentration on the oxidative refolding of denatured-reduced lysozyme of high concentration in the presence of artificial chaperone , that is, cetyl trimethyl ammonium bromide and β-cyclodextrin,was studied.

研究了表面活性剂十六烷基三甲基溴化铵加β-环糊精和盐酸胍对高浓度变性-还原溶菌酶氧化复性的影响，利用基于二态复性模型的表观动力学模型分析了溶菌酶的复性过程。

It is important to produce the effective and costless cellulase for the energy and the environment due to the cellulose abundance and immense potential.

目前，纤维素酶的生产主要是采用微生物发酵的方法，以丝状真菌为主，产酶效果最好的真菌是里氏木霉。

And Echinochloa crusgalli L. were studied. The result showed that both of the aqueous extract from aerial part and root of T. repens inhibited the germination rate of weed seeds, root activity and respiratory rate , the activities of superoxide dismutase peroxidase and catalase of germinating seeds, enhanced the activity of peroxidase and the content of malondialdehyde.

结果表明，白三叶草地上部分水浸液和根系分泌物显著抑制苘麻和稗草种子的发芽率，降低了杂草种子萌发过程中超氧化物歧化酶、过氧化氢酶的活性，抑制了杂草种子根系活力，显著提高了杂草种子过氧化物酶活性和丙二醛的含量。

According to previous reports, the capability of endolysin to digest the cell wall when applying exogenously to bacterial cells has enabled its use as alternative antibacterials.

先前的研究报告指出，使用外加溶菌酶的方式作用於细菌，能够使细菌细胞壁分解而杀死之，这也使得溶菌酶具有作为替代性杀菌剂的发展潜力。

The study make a base for research of enzymatic properties and probable application in the future.

克隆表达的成功为该酶的酶学性质研究和可能的应用打下了基础。

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。
