查询词典 glycolaldehyde

Objective To investigate the inhibitory effects of Taurine on the cellular toxicity induced by glycolaldehyde.

目的：研究牛磺酸对乙醇醛所致细胞毒性的抑制作用。

"This is an important discovery as it is the first time glycolaldehyde , a basic sugar, has been detected towards a star-forming region where planets that could potentially harbor life may exist," said researcher Serena Viti of the University College London.

&这是一项重要的发现，因为这是首次在恒星形成的区域内发现基本糖类乙醇醛，这个区域可能存在拥有生命的行星，&伦敦大学学院的研究人员塞雷纳·维蒂说。

An international team of scientists used the IRAM radio telescope in France to detect glycolaldehyde in a massive star-forming region of space, some 26,000 light-years from Earth.

一组跨国科学家，利用法国毫米电波天文研究所的射电望远镜，在太空一个大规模的恒星形成区发现了乙醇醛，该区距离地球大约2.6万光年。

Called glycolaldehyde , the sugar molecule is considered a life ingredient because it can react with a substance called propenal to form ribose , a central constituent of ribonucleic acid, which is similar to DNA and considered one of the central molecules in the origin of life .

由于乙醇醛可以与一种叫做丙烯醛的物质发生反应，然后形成核糖，而核糖是核糖核酸的重要组分，核糖核酸类似于脱氧核糖核酸，被认为是导致生命形成的重要分子。

Methods The inhibitory effects of Taurine (50 mmol·L-1) on glycolaldehyde (0.1 mmol·L-1) induced DNA damage in spleen lymphocytes of mice were studied in vitro using single cell gel electrophoresis,and 2,4-dinitrophenylhydrazine measurement was used to detect quantitatively the effects of Taurine on carbonyl compound contents in a reactive system.

采用单细胞凝胶电泳技术检测牛磺酸（50 mmol·L-1）对乙醇醛（GA， 0.1 mmol·L-1）所致小鼠脾淋巴细胞DNA损伤的抑制作用，并用2，4-二硝基苯肼法定量检测牛磺酸对反应体系中乙醇醛含量的影响，同时设乙醇醛阳性对照组和PBS阴性对照组。

Results After 50 mmol·L-1 Taurine was added to the spleen lymphocyte suspension containing 0.1 mmol·L-1 glycolaldehyde, the cellular DNA damage rates were markedly decreased (P.01) and the migration distances of DNA were significantly reduced (P.01) as compared with positive control group, and Taurine reduced the carbonyl compound contents in a reactive system in a dose-dependent manner.

结果：在0.1 mmol·L-1乙醇醛溶液中加入50 mmol·L-1牛磺酸后，小鼠脾淋巴细胞DNA的损伤率较阳性对照组明显降低（P.01），彗星实验的迁移距离也显著缩短（P.01），牛磺酸呈剂量依赖性明显降低反应体系中乙醇醛的含量。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
