As the Yayoi population explosion continued, and as all the best swamps or irrigable plains suitable for wet rice agriculture began to fill up, the archeological evidence suggests that war became more and more frequent: that evidence includes mass production of arrowheads, defensive moats surrounding villages, and buried skeletons pierced by projectile points.

随着弥生时期人口爆涨的继续，及所有适合水稻农业的优质湿地和可灌溉平原被占用，考古学证据显示战争开始变得越来越频繁：证据包括箭镞的大规模生产、环绕村庄的防御用壕沟和埋于地下的被尖锐抛射体扎穿的骨架。

However, there is now increasing evidence that CD44 is assembled in a regulated manner into membrane-cytoskeletal junctional complexes and, through both direct and indirect interactions, serves to focus downstream signal transduction events.

然而，现在越来越多的证据表明CD44的装配以一种调控模式嵌入膜骨架复合物，并通过直接和间接的相互作用为下游信号转导重点服务。

The cytoskeleton of G. lamblia can be effectively injured by dihydroartemisinin.

双氢青蒿素对体外蓝氏贾第鞭毛虫滋养体的细胞骨架有明显的损伤作用。

AIM: To detect and observe the effect of dihydroartemisinin on the cytoskeleton of Giardia lamblia in vitro.METHODS: The trophozoites of G.

目的：观测双氢青蒿素(dihydroartemisinin， DHA)对体外培养的蓝氏贾第鞭毛虫滋养体细胞骨架的损伤作用。

Through PCR and sequencing, a fragement sequence with lamin gene feature was obtained. It was of of transcriptional activity. In addition, we also cloned and identified giardial DNA topoisomerase gene.Our phylogenetic analysis showed that although Giardia diverged early but not first, thus, it is not as primitive as thought before.

然后进行了核纤层蛋白基因的扩增和鉴定，获得了一个具有明显核纤层蛋白基因特征的基因序列片段，并证明它是表达的且不具内含子；此外还克隆鉴定了作为核骨架重要成分的DNA拓扑异构酶II的基因；在此基础上结合已报导的不同进化地位生物上的数据进行了分子系统学分析，结果显示贾第虫虽然分支较早，但不象过去所认为的那么原始。

Nineteen spots were changed significantly after FA treatment.Thirteen proteins were identified by peptide mass fingerprinting or peptide sequence analysis,including putative nucleoside diphosphate kinase,elongation factor 1-gamma,triosephosphate isomerase,60S acidic ribosomal protein P0,heat shock protein 75 kDa,similar to heat shock 70kD protein binding protein,annexin I,hypothetical protein FLJ34423,microtubule-actin crosslinking factor 1,lamin B2,ATP synthase alpha chain,mitochondrial precursor,proteasome subunit alpha type 6.These identified proteins involved in energy metabolism,translation and RNA processing,protein folding,redox regulation,cell structure and cell signaling.
