荧光复合扩增检测3个Y—STR基因座单倍型

目的建立检测3个Y-STR基因座Y-GATA-A7.1、DYS456和DYS443的荧光复合扩增体系,并获取中国汉族人群单倍型频率分布。方法用荧光标记引物对郑州地区203名汉族男性无关个体进行3个基因座复合扩增,ABI3100型遗传分析仪检测、分型。结果Y-GATA-A7.1、DYS456和DYS443基因座分别检出5、6和6个等位基因,其基因多样性(GD值)分别为0.6692、0.5839和0.7053。三个基因座构成的单倍型共有44种,单倍型多样性(HD值)为0.9523。结论建立的3个Y-STR基因座荧光标记复合扩增系统具有很高的识别能力,可应用于法医学实践。     

“一打三反”运动是怎样掀起来的

"一打三反"运动源于1970年中央发出的三个文件,即<关于打击反革命破坏活动的指示>、<关于反对贪污盗窃、投机倒把的指示>和<关于反对铺张浪费的通知>.它是"文革"中深入"斗、批、改"的一个重要措施,打击了一些反革命分子和各类犯罪分子.但在当时"左"倾思想的指导下,在贯彻"公安六条"和许多地区一派掌权的情况下,也制造了不少冤假错案.     

论"核心期刊"泛化的负效应及原因

设立核心期刊是为图书情报机构馆藏期刊提供"参考",为读者选择、阅读期刊文献提供"门径".但是,近年来,核心期刊被广泛运用于津贴评定、职称评审、论文评奖、期刊评价等方面,演变成一种评价尺度.于是,影响了作者群体的正常分布,干扰了学报正常的出版秩序,败坏了编辑出版界的行业风气,等等负面影响.究其原因,主要是对核心期刊的认识不足,缺乏衡量学术期刊质量的权威标准,科研绩效评价体系的不健全等.     

"天人合一"与人和自然的平衡之误

环保成为社会的共识是现代工业社会条件下的产物,是建立在实践需要和科学进步的基础上,古代中国没有真正的"天道",只有"人道"."天人合一"思维重点是指人的行为活动符合传统伦理道德原则,而不是人与自然的生态平衡,是心灵自我超越的最高境界.     

"大话"文化:"电子场景"下青年文化的"中区倾向"

"大话"文化是"电子场景"下成长起来的青年人在行为方式上的主动变革,从而形成的一种"中区倾向"的行为模式,"大话"文化只能以青年文化的面目出现.对于"大话"文化现象,不能轻易地以价值判断对其进行盖棺定论,它实际上是人们在"电子场景"下行为模式转变的一个信号而已.     

变化中的世界与中国

The general toxicology unknown. I. The systematic approach

The general toxicology unknown often presents challenges and interests to toxicologists. A systematic analytical approach to search for drugs or poisons is presented here. The preliminary screening analyses were as follows: alcohol by gas chromatography (GC), ethchlorvynol colorimetric analysis, enzyme multiplied immunoassay technique (EMIT), basic drug screening by GC, and neutral and weakly acidic drug screening by GC. Other additional analyses were performed depending on the special circumstance of each individual case and the results of these preliminary analyses. Positive findings were confirmed by computerized gas chromatography/mass spectrometry when practical. Quantitation was performed by GC whenever possible.     

The impact of the financial sector on economic development: Some cross-section evidence

Conclusion This paper has attempted to analyze the effect of the development of the financial sector, as reflected by the extent of financial deepening, in the economic development of countries. The Theoretical framework integrating financial growth to real growth is basically an adaptation of the Gurley-Shaw theory of finance in the development context, but with emphasis placed upon the supply-leading role of the financial sector. The empirical results of this study although not conclusive, indicate that financial deepening leads to a higher rate of capital accumulation and a higher level of per capita income. The lack of definitiveness of our evidence in support of the financial theory of economic development is due to a lack of comparable data on financial institutions, other than banks, for the different countries. Thus, although our study lends support to the supply-leading thesis, further judgement of the thesis must await more detailed empirical analyses.
