The codA gene encodes cytosine deaminase, which can deaminate nontoxic compound 5-fluorocytosine (5-FC) to the highly cytotoxic compound 5-fluorouracil (5-FU). 5-FU can influence the cells survival through interference with the synthesis metabolism of the RNA and DNA.

codA基因在细菌体内编码胞嘧啶脱氨酶，CD能把对细胞无毒的5-氟胞嘧啶(5-FC)脱氨成为有毒的5-氟尿嘧啶(5-FU)。5-FU通过干扰RNA和DNA的合成代谢从而影响细胞的生存。

Similar responses were obtained in decerebrate, isoflurane-freerats administered etomidate and in isoflurane-anesthetized ratsadministered propofol.

在去大脑、给予依托咪酯未用异氟醚的大鼠或给予异丙酚的异氟醚麻醉大鼠，也可以记录到相似的反应。

aim: to prepare floxuridine diacetate solid lipid nanoparticles so as to improve the treatment efficacy and reduce the side effects of floxuridine.

目的：为了提高氟尿苷的疗效，降低其毒副作用而制备氟尿苷二乙酸酯固体脂质纳米粒。

The trifluoroethylester silane was synthesized by modifying a PEG diacid to form the corresponding bistrifluoroethylester, followed by a reaction with 3-aminopropyltriethoxysilane.

通过用PEG二酸修饰合成三氟乙基乙烯醚硅烷，由此形成相应的双丙烯酰胺三氟乙基乙烯醚，再将其与3-APS相互作用。
