This study used microsatellite markers attempts to:(1) discover the genetic variation among sampling populations and reconstruct the phylogeographic scenario;(2) confirm the direction of gene flow (3) conjecture the causation and time of introgressive hybridization.

本文的研究发现两种石鸡之间具有显著的遗传分化(Fst=0.2979，Rst=0.1942，Neis D_A=3.016)。8个微卫星位点在大石鸡88个样本扩增出40个等位基因，在石鸡64个样本扩增出35个等位基因。

Bidens pilosa var. radiata, one of the rapid expanding invasive weeds, has become prevailing throughout Taiwan. A study on the result enhanced by the breakdown of geographic isolation with the native varieties in genetic variation, population structure and introgressive hybrization is really in need. In this study the genetic variation and population structure among the varieties of Bidens pilosa complex were studied using ISSR markers.

在台湾Bidens pilosa种群在外部形态及分布上均非常类似，加上大花咸丰草又属极具侵略性的新归化种，在与其他自生变种又无明显隔离下，是否增加种间之交流与渐渗杂交之机会及对族群结构的影响，实有深入探讨之必要。

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.

目的：组织块培养法培养人胚胎生殖干细胞，通过检测细胞所表达的阶段特异性胚胎抗原1 和3(stage-specific embryonic antigen-1、3 ，SSEA-1、SSEA-3)，对未分化的人EG 细胞进行特异性的生物学鉴定。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
