屠宰猪肝和血清中乙型肝炎病毒及戊型肝炎病毒的检测

应用1对乙型肝炎病毒(HBV)S基因保守区的引物,采用PCR方法从屠宰猪肝、血清中检测到了HBV,序列分析表明,扩增片段与已发表的HBV S基因的同源性高达98%~100%。电镜负染色样品观察结果表明,在HBV表面抗原ELISA检测强阳性反应的血清样品中存在有形态、大小与人HBV Dane颗粒和小球状颗粒相似的病毒粒子。针对戊型肝炎病毒(HEV)ORF2/ORF3重叠区设计了简并引物,采用巢式RT-PCR对屠宰猪肝和血清样品进行了检测。结果表明,部分屠宰猪肝中存在HEV。     

猪和兔附红细胞体的体外培养

用RPMI1640和小牛血清按不同比例混合作为体外培养猪和兔附红细胞体的基础培养基,同时以去掉红细胞上自然感染的附红细胞体后的红细胞泥作为培养附红细胞体的寄生载体,进行猪和兔附红细胞体的体外培养。培养结果表明,以 RPMI1640 与小牛血清按 6∶4 比例混合,同时选用兔红细胞泥作为载体的培养效果最佳,接种感染了附红细胞体的猪、兔阳性红细胞后 24 h生长达到高峰,感染率分别为40.2%和31.0%,而采用猪红细胞泥作为培养载体时红细胞感染率无明显升高。     

福建汉族人群21个常染色体STR基因座的遗传多态性

目的调查福建汉族人群21个常染色体STR基因座多态性参数,评估GlobalFilerTM Express试剂盒的法医学应用价值。方法应用GlobalFilerTM Express试剂盒复合扩增检测741名福建汉族无关个体,计算21个常染色体STR基因座的群体遗传学参数。结果 21个常染色体STR基因座的基因型分布均符合Hardy-Weinberg平衡(P0.05),21个STR遗传标记均具有高度多态性,杂合度为0.589~0.914,个体识别率为0.754~0.992,多态信息含量为0.520~0.940,非父排除率为0.278~0.825。其中以SE33基因座多态性程度最高。结论 GlobalFilerTM Express试剂盒的21个STR基因座有较强的系统效能,该试剂盒可应用于福建汉族人群的法医学个体识别及亲权鉴定。     

体育教学中进行思想品德教育的探索与实践

在体育教学中,可根据教材内容和特点选择不同的组织教法,结合课堂常规和教学条件等对学生进行思想品德教育,其教育效果良好。     

论体育教学中的道德教育

体育中的道德教育问题，历来被教育家、体育家所推崇和重视。根据体育教学的特点、目的和任务，培养学生正确的道德评价能力和道德意识，充分发挥体育的育体、育人功能，培养学生成为完全型人格的人，是体育教学中进行道德教育的必然选择。     

Gender Mainstreaming and Global Governance

This article seeks to explain the variable implementation of gender mainstreaming as a `policy frame' over time and across various international organisations (I.O.s). In the years since the U.N. Fourth World Women's Conference in Beijing (1995),mainstreaming has been endorsed and adopted by a wide range of international organisations, and we compare the adoption and implementation of mainstreaming in four specific I.O.s: the World Bank, the United Nations Development Programme, the Organisation for Security and Cooperation in Europe, and the European Union. The rhetorical acceptance of mainstreaming by various international organisations, however, obscures considerable variation in both the timing and the nature of the mainstreaming process within and among organisations. This variation, in turn, can be explained in terms of the categories of political opportunity, mobilising structures and strategic framing, which have been put forward by social movement theorists. This revised version was published online in July 2006 with corrections to the Cover Date.

Report of the Commission on the Consequences of Devolution for the House of Commons (the McKay Commission)

The report of the McKay Commission on the Consequences of Devolution for the House of Commons is reviewed. The Commission, which contained experts on parliamentary procedure, raised a number of important and difficult questions; the answers are less impressive than the questions. In view of the difficulties of any scheme, including that proposed by the Commission, for what is popularly known as “English Votes on English Laws,” policymakers should revisit one of the options that was specifically ruled out of McKay's terms of reference. This would be a reduction in the numbers, but not the powers, of MPs from Scotland, Wales, and Northern Ireland in the way that applied to Northern Ireland between 1922 and 1979.     

表达猪瘟病毒E2蛋白重组减毒鼠伤寒沙门氏菌活载体疫苗株的构建及动物免疫试验

为了构建表达猪瘟病毒E2蛋白的口服重组减毒鼠伤寒沙门氏菌活载体疫苗株,亚克隆猪瘟病毒E2基因,将其插入到表达载体pYA3341中,构建了重组质粒pYA3341-E2。将该重组质粒电转入鼠伤寒沙门氏菌疫苗株X4550(缺失asd、cya、crp基因),获得重组疫苗菌株X4550(pYA3341-E2),并对重组菌表达的E2蛋白进行SDS-PAGE和Western-blot分析、测定其在体内外的稳定性、生长曲线、安全性及动物免疫试验。结果显示,重组菌能表达E2蛋白且表达的蛋白能与猪瘟病毒阳性血清特异性结合。在体外营养选择压力下,重组菌株在体外可稳定地携带重组质粒传代繁殖,在体内可稳定地定居于肠系膜淋巴结和脾。小鼠口服试验证实重组菌无毒性,安全可靠。动物免疫试验表明,口服重组菌免疫猪产生了抗E2蛋白抗体。淋巴细胞增殖试验表明,重组菌能诱导机体产生较强的细胞免疫应答。结果表明,成功构建了能稳定表达猪瘟病毒E2蛋白的口服减毒鼠伤寒沙门氏菌疫苗株,为研究猪瘟口服基因工程疫苗奠定了基础。
