"Understanding this toggle switch might ultimately enable scientists to find ways to stop cells from metastasizing, which is the most deadly trait of cancer," said the study's lead investigator, Mariano Garcia-Blanco, M.D., Ph.D., professor of molecular genetics and microbiology.

"对这个开关的了解可能最终会使科学家们能够找到阻止细胞转移的方法,而转移是癌细胞最致命的特征。"研究的首席研究员Mariano Garcia-Blanco说(分子遗传学和微生物学博士)。

A dye recycled photosensitization system has been designed. As a result of studies in the mechanism of electron transfer reaction of xanthene iodonium salt, it is proposed that the dye-recycled process consists of three-step reactions during the photosensitization: The oxidative fading product of dye is formed through electron transfer under irradiation; In the presence of H-donor, product changes into acidic leuco dye product; Product undergoes deprotonization under action of base to regenerate initial dye.

本文设计了染料循环再生的光敏反应体系,通过对占吨碘翁盐电子反应机制的深入研究,提出了占吨染料在光敏反应过程中的染料再生循环,它依次由三个反应过程组成:在光作用下,通过电子转移反应,产生染料氧化褪色体;在H给体存在下,通过H转移反应,使产物转化为染料酸式隐色体;在碱作用下,发生去质子反应,染料再生回复到染料的起始结构。

The chemical structure of the product was characterized by means of the melting point and IR. The results show that tetraethylammonium bromide which was used as a phase transfer catalyst in this reaction had optimization effect on the interfacial diffusive reaction of BTC and PNP. Higher concentration of sodium hydroxide, lower temperature and a higher dosage of BTC produced a small amount of 4-nitrophenyl chloroformate, while lower concentration of sodium hydroxide and a lower dosage of BTC made reaction incomplete, which affected the yield.

结果表明,在碳酸二(4-硝基苯基)酯合成中使用的相转移催化剂四乙基溴化铵对受界面扩散控制的BTC气与对硝基酚钠反应有良好的相转移催化效果;氢氧化钠质量分数较低时,酚钠盐向溶有BTC的油相扩散速度较小,较高时会产生氯甲酸对硝基苯酯;温度较低、BTC量较高时,会产生少量氯甲酸对硝基苯酯,BTC用量较低会使反应不完全,这些都影响着收率。

The development of research strategies and novel molecule methods in recent years have made a more careful analysis of HGT possible under natural and artificial conditions. Furthermore, horizontal transfer of catabolic gene in environment enhances biodegradation of recalcitrant organic compounds. Particularly, the delivery of catabolic gene information of conjugative plasmids to bacterial population in situ has great potential in bioenhancement.

近年发展起来的研究策略和新的分子生物学方法使人们能对自然和人工模拟状态下的水平基因转移进行更精细的分析,降解基因在环境中的水平传播促进了难降解有机物的生物降解,尤其是携带降解基因的接合质粒向原位细菌种群中的转移在生物强化中具有巨大的潜力。

Nevertheless, its fluorescence is enoughintense to be investigated the switch properties in aqueous solution. 5. The results of fluorimetric titrations and spectrophotometric titrations indicate that,for 〓 and 〓, fluorescence of fluorenyl was quenched by transfer of electron from metalcenter to photoexcited state of fluorenyl during coordination of Cu or Ni.
