法律术语词的通俗化研究

法律术语词的通俗化是汉语词汇系统中词义发展演变的一种重要方式。对法律术语词通俗化的两种主要途经——隐喻式通俗化和引申式通俗化分别进行举例分析,明晰其通俗化的语义、语法、语用等方面的特点,探讨促使法律术语词发生通俗化变化的内、外动因。     

耦合三量子阱中隧穿诱导的可控光学增益和吸收

考虑自发辐射相干,解析地研究了半导体耦合三量子阱系统中探测光和信号光场的增益和吸收性质。基于光与原子相互作用的半经典理论,通过建立耦合量子阱中自发辐射相干的理论模型,求得了系统的探测光和信号光场的线性极化率。结果表明,量子阱内部自发辐射相干强度及外部控制光场能实现对探测光和信号光的线性增益和吸收性质的有效调节,进而显示隧穿诱导透明单、双窗口及增益之间的相互转换。     

延边地区圈养黑熊基因DNA中部分微卫星位点的探讨

本研究采用分光光度法及琼脂糖凝胶电泳比较从黑熊组织、血液以及毛发中提取的黑熊基因组DNA,发现提取的DNA浓度及纯度均可满足后续试验的需要。其中毛发DNA提取方法具有高灵敏度、操作简单、非损伤等特点,有助于开展珍稀濒危物种和性情凶猛动物的遗传特性研究。本文还根据文献中黑熊的11个微卫星位点设计并合成引物,进行了不同引物PCR最佳反应条件的筛选。对黑熊DNA基因组PCR扩增结果发现其中10对引物能扩增出较明显的扩增带,为后续的黑熊亲子鉴定及遗传特异性分析实验提供了有价值的资料,为其亲权概率的准确性提供了良好的参考依据。     

Angiotensin Converting Enzyme Gene Polymorphism and its Association with Hypertension in South Indian Population

Hypertension, a well known risk factor for various cardiovascular, peripheral vascular and renal events is an important public health challenge. Renin angiotensin system (RAS) being the most vital pathogenic mechanism of hypertension is mediated by a key component; the angiotensin converting enzyme (ACE). The present study was aimed to know the relationship of ACE gene polymorphism and the possible risk of development of hypertension in south Indian population. The study included 101 clinically diagnosed hypertensive patients without any associated disease condition and 81 age and sex matched apparently healthy controls. Genotyping was performed using a polymerase chain reaction, (PCR) amplification of the intron 16 fragment harboring the 287 bp Alu repeat sequence. Three possible genotypes D/D, I/I homozygous and I/D heterozygous were analyzed where the D/D genotypes corresponds to higher ACE levels (D-Deletion, I-Insertion). The PCR products were separated on 2 % agarose gel. Statistical analysis was performed using SPSS.15 software program. We found a significance in frequency of D/D genotype in the hypertensive patients compared to the control group (p = 0.0005, odd’s ratio = 4.157). This suggested that ACE (D/D) genotypes are more prone for the development of hypertension. This is relatively a pilot study; but nevertheless may assist in identifying the pathophysiological cause of hypertension.     

ApoE基因多态性与运动防治原发性骨质疏松效果的关系

目的：探讨不同ApoE基因型人群对适宜健骨运动处方防治原发性骨质疏松的敏感性，为制定基于基因多态性的个性化运动处方提供理论依据。方法：74名原发性骨质疏松患者按ApoE基因型随机分为ε2组、ε3组和ε4组，进行为期3个月的有氧及抗阻运动训练，双能x线骨密度吸收仪（DxA）测定运动前后骨矿含量、腰椎（L2-4及髋部骨密度（BMD）的变化。结果：ε4组BMC运动前后的变化率高于ε2组0P〈0．05）；L2-4BMD运动前后无显著变化；ε4组髋部BMD运动前后的变化率显著高于ε2组（P〈0．05）。结论：运动疗法防治原发性骨质疏松的效果受ApoE基因多态性的影响，其中ε4型人群通过运动疗法防治骨质疏松的效果较好。

传播学与翻译的创造性

翻译的创造性是指翻译过程中译者对原文信息进行增添、删除及重组,这一现象虽然背离了传统译论中“信”的标准,但若把翻译学纳入传播学,传播学的相关理论则能够为之提供有力的理论依据。
