Results: The homogeneous enzyme was obtained on a single step by affinity chromatography from the supernatant of transformed cells, and its reductive activity of menadione was 18.6-fold of the supernatant of the empty-transformed cells and 7.3-fold of transformed cells.

结果：诱导表达后的细菌裂解上清液经一步亲和层析后得到单一酶蛋白，其对K3的比活性分别是原空白菌裂解上清液和经诱导表达后的菌裂解上清液的比活性的18.6和7.3倍。

Center for Molecular Biology, Shantou University Medical College, Shantou 515041, China［Abstract］Objective: To detect the reduction of rabbit NADP-dependent retinal reductaseon menadione, and to identify its reductive production.

目的：检测兔辅酶Ⅱ依赖性视黄醛还原酶对维生素K3的催化活性并对该酶还原K3所生成的产物进行鉴定。

Rabbit-NDRR can reduct menadione and its reductive product is menadiol.

兔NDRR对K3存在还原活性，并生成K4。

It could be explained by the fact that heat treatment could liberate some bonded antioxidants and facilitate Milliard reaction that produces reductive products.

推测由於加热处理释放一些原本结合态的抗氧化活性物质或促进梅纳反应产生还原性产物。

But to read these early dialogues as performing such a purely negative function also seems to be too reductive.

但是，阅读这些早期的对话，作为履行这种纯粹的负面作用也似乎过于还原。

The view I am advancing is ontologically reductive but not reductionist in the sense that many anti-reductionists find objectionable.

这个观点的推进是'存有上的还原'，但不是反还原论者发现可反对的那种还原论。

With reductive atmosphere annealing at 900-1000℃, STO thin films with (200)-oriented and smooth surface were obtained with optimized parameters.

在900-1000℃下还原气氛中退火制备STO薄膜。优化工艺参数得到(200)单一取向且表面平整的STO薄膜。

Spicy , slightly spirity and herbal aromas of cassis , blackberries and polished cedar chocolate oak overlie some leathery , reductive influences .

辛辣，具有少许的烈性，黑醋栗的草木芳香，黑莓，被磨制过后的雪松和巧克力的醇香最终掩盖了皮革的气息。

Whenpyridine was used as reductive decomposing agent, the expecting cholest-4-en-3,6-dione-22-al was obtained. However, when Zn/HOAc was used to decomposethe ozonide, C-4,5 double bond was further reduced to give cholest-3,6-dione-22-al as main product. 2 For the side-chain construction of compound (1), the solid-liquid phase-transfer Wittig reaction was used. When (3-methyl-2-oxobutyl)-triphenylarsonium bromide was used as reagent, the reaction can be carried out inmild reaction condition and the yield is higher than that when phosphorane wasused.

但使用Zn／HOAc作为分解剂时，却得到其氢化产物胆甾-3， 6-二酮-22-醛；2在甾体支链引入过程中，采用固-液相转移Wittig反应的方法，用(3-甲基)-2-氧丁基三苯基溴化胂作为试剂，反应在非常温和的条件下便可完成，而且产率比传统采用膦烷的方法更高；3在对某些甾酮化合物的选择性还原反应研究时，发现在〓还原体系中，当加入某些金属离子后，反应有更好的区域选择性和立体选择性。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
