Detection of parasite eggs from a moat encircling the royal palace of Silla, the ancient Korean Kingdom

We conducted a paleo-parasitological study on soil samples from the ancient moat ruins of Weolseong palace, of the Silla Dynasty (BC 57–AD 935) of Korea. Based on the cultural remains found in the mud-soil layer, the layer was precipitated onto the floor of a moat between the 5th and 8th centuries AD. We found Trichuris trichiura eggs only in that mud-soil layer, whereas no parasite eggs were identified in the other archaeological strata of the ruins. As T. trichiura eggs are shed only in human feces, we speculated that palace toilet contents were continually drained into the moat; therefore, at a certain point in time after construction, the moat finally became a ditch around the palace. Structures in the stone embankments of the moat, possibly designed to make the water flow continuously in one direction, might reflect the Silla people's efforts to alleviate the ever-increasing problems inherent in a moat.     

从工会法律地位的演进看工业化时期英国政府劳资政策的嬗变(1799—1974)

自1799年《反结社法》颁布至《1974年工会和劳资关系法》出台的近两百年间,英国工会的法律地位经历了从非法状态到被有限承认再到享有法定特权的漫长历程,伴随着工会地位的这种转换,英国政府的劳资政策也相应发生了从立法打压到建立仲裁调解制度再到确立集体谈判制度的历史嬗变。     

Amplification and sequencing of Trichuris trichiura ancient DNA extracted from archaeological sediments

Despite high prevalence of Trichuris trichiura infection, PCR-based analysis on T. trichiura from archaeological samples has not been established so far. In the present study, we sought to perform PCR-based amplification of T. trichiura aDNA using the sediments from medieval tomb of Korea. The presence of Trichuris eggs were first detected by microscopic observation; then confirmed by PCR-based aDNA analysis. Obtained sequence showed 100% homology to that of the small subunit ribosomal RNA (SSUrRNA) gene of T. trichiura but distinct from that of other Trichuris species. PCR-based aDNA analysis in this study can serve as effective method to confirm the presence of T. trichiura eggs in the soils or coprolites collected from archaeological sites.     

公仆形象留土乡

1954年,中国唯一的土族自治县——青海省互助土族自治县成立时,全县已有100余名土族男女青年成为本县党政机关和国有企事业单位的干部,其中有不少的先进分子已成为中国共产党党员、有的还担任县乡各级领导职务。李延武、李友楼、乔登云、张惠统就是这一代先进分子中的优秀代表。风风雨雨几十年,他们始终奉行全心全意为人民服务的     

柴燕平在摄影中放纵心灵

<正>读万卷书,行万里路。对于摄影人来说,"万里路"必不可少,这也正是他们的志趣所在。30多年来,柴燕平先生游历祖国的名山大川,足迹遍布大江南北。问及具体到过哪里,柴先生自豪地说,"除了新疆,祖国的其他省市我都去过"。柴先生从未把眼界局限于国内,马来西亚、泰国等地,他均去过不止一次。如果说第一次是浮光掠影,那么柴先生多次的故地重游,一定使他对当地的山川风
