The recent studies on comparative genomics have further suggested that a third round of fish-specific genome duplication in ray-finned fishes might have occurred at about 350 million years ago, during the divergence between teleost fish and basal actinopterygian lineages. Therefore, FSGD might be related to the increase in species number and biological diversity during this time.

近期的系统基因组学研究资料进一步提出，在大约350百万年，辐鳍鱼还发生了第三次基因组复制，即鱼类特异的基因组复制(fish-specific genome duplication， FSGD)，且发生的时间正处在"物种极度丰富"的硬骨鱼谱系和"物种贫乏"的谱系出现分歧的时间点，表明FSGD与硬骨鱼物种和生物多样性的增加有关。

Objective: Identify the human embryonic germ cells by observing the expression of its specific surface markers SSEA-1、SSEA-3. Methods: Human embryonic genital ridges, dorsal mesenteries(5-9 weeks post-fertilization) were cultured without any cytokines, while the fibroblasts derived from the isogenous embryo were used as the feeder layer.

Nornicotine is produced by the N-demethylation of nicotine during the post-harvest treatment of tobacco leaves.Nornicotine in tobacco serves as the precursor in synthesis of the well-characterized carcinogen N'-nitrosonornicotine, one of the tobacco-specific nitrosamines, and consequently damages the health of tobacco smokers and passive smokers.

烟叶的采收后处理和加工过程中，大量的尼古丁经去甲基化作用生成了去甲基尼古丁，后者是烟草特有的亚硝胺类(tobacco-specific nitrosamines， TSNAs)致癌物——亚硝基去甲基尼古丁(nitrosonornicotine， NNN)的前体，与人类健康息息相关。
