Lower mercury methylation was expected in these two reservoirs.With the development of reservoir,it is possible that the methylmercury concentrations will increase due to autochthonous and extraneous organic materials,and methylmercury may be released due to thermal stratification.But this was not confirmed.

通过研究发现目前库区环境汞的甲基化率低，但随着水库生态系统的不断演化，内源和外源营养物的输入及水体在温度分层其间自身甲基汞的形成，导致水体甲基汞含量的逐渐增加，但仍需进一步的研究证实。

In the NPC cell lines,loss of BLU expression correlated with hypermethylation of the 20 CpG sites in the 5′ region of BLU(approximately -292bp to -23bp upstream the translation start site)as revealed by bisulphite sequencing. Expression of the gene was restored aftertreatment with 5-aza-2-deoxycytidine in CNE2, suggesting that repression of BLUtranscription might at least be partially mediated by promoter methylation.

结果显示，BLU基因翻译起点ATG上游-292--23bp区间内的20个CpG位点在5例细胞系中均被完全或者部分甲基化，与基因的表达缺失呈负相关关系；去甲基化试剂5-Aza-CdR处理CNE2后基因表达部分恢复，说明甲基化至少是引起BLU基因转录抑制的部分原因。

Starting from p-hydroxybenzaldehyde, isovanillin (3-hydroxy-4-methoxybenzaldehyde) was synthesized by three-step reactions of bromination,methylation and hydrolysis.

以对羟基苯甲醛为原料，经溴代、甲基化和水解3步反应合成了异香兰素，改进并优化了合成路线。
