Sequences of the Cytochrome C Oxidase Subunit I (COI) Gene are Suitable for Species Identification of Korean Calliphorinae Flies of Forensic Importance (Diptera: Calliphoridae)

Abstract:  Calliphorinae fly species are important indicators of the postmortem interval especially during early spring and late fall in Korea. Although nucleotide sequences of various Calliphorinae fly species are available, there has been no research on the cytochrome c oxidase subunit I (COI) nucleotide sequences of Korean Calliphorinae flies. Here, we report the full-length sequences of the COI gene of four Calliphorinae fly species collected in Korea (five individuals of Calliphora vicina , five Calliphora lata , four Triceratopyga calliphoroides and three Aldrichina grahami ). Each COI gene was amplified by polymerase chain reaction and directly sequenced and the resulting nucleotide sequences were aligned and analyzed by MEGA4 software. The results indicate that COI nucleotide sequences can be used to distinguish between these four species. Our phylogenetic result coincides with recent taxonomic views on the subfamily Calliphorinae in that the genera Aldrichina and Triceratopyga are nested within the genus Calliphora .

法律空间建构的逻辑演进

近年来,学术界越来越多的学科正在向空间理论研究转向.法律的空间性研究也具有一定学术和应用价值.本文以于法律空间性为研究视角,从三个不同的维度进行逻辑推演:维度构成、作用机制和研究方法.本研究的目的是探索利用抽象的数学模型来建构一个法律空间的可能性,特别是在信息技术高速发展的背景下,借鉴卢曼开创的系统法学方法论,以解释、...     

南海渔业资源衰减相关问题研究

自20世纪70年代以来,南海渔业资源一直处于逐渐衰减的状态。渔民的非法捕捞行为和东南亚南海周边国家基于争取更多主权权利而采取的渔业政策是影响南海渔业资源衰势的重要原因。近年来南海主权争端问题的再度激化制约了南海周边各国共同推动南海渔业合作机制的发展。目前,国际社会已有《联合国海洋法公约》等国际法规范和相对成熟的共同海域渔业资源保护机制。然而,能否推动在南海地区发挥这些已有机制的积极作用仍有赖于南海周边国家对南海共同渔业资源的政策和态度。     

Rapid and simple GC-MS method for determination of psychotropic phenylalkylamine derivatives in nails using micro-pulverized extraction

A rapid and simple gas chromatography-mass spectrometry (GC-MS) method was developed and validated for the simultaneous detection and quantification of five psychotropic phenylalkylamines (amphetamine, methamphetamine, 3,4-methylenedioxyamphetamine, 3,4-methylenedioxymethamphetamine, and norketamine) in toenails. After external decontamination, nail clippings were mechanically pulverized with a bead mill and then incubated in methanol under ultrasonication at 50°C for 1 h. The resulting solutions were evaporated to dryness, derivatized, and analyzed by GC-MS. The intra- and inter-day precisions were within 10.7% and 13.9%, respectively. The intra- and inter-day accuracies were -4.2% to 5.0% and -2.4% to 8.4%, respectively. Limits of detection and quantification for each analyte were lower than 0.024 and 0.08 ng/mg, respectively. The recoveries were in the range of 80.6-87.5%. The results indicated that the proposed method is a simple, rapid, accurate, and precise for quantification of five phenylalkylamines in nails. The method was successfully applied to the simultaneous detection and quantification of phenylalkylamines in nail samples of possible drug abusers.     

论东日本大地震对在日华侨华人未来发展走向的影响

3·11东日本大地震以及由此引发的海啸和核泄漏,给在日华侨华人造成了新的迷茫和困惑.战后日本长期以社会稳定与经济繁荣而为人称道,而现今的日本是否还是值得留恋的宜居之地?在日华侨华人面临着新的抉择.日本《中文导报》与笔者的“问卷调查”显示:尽管感到在日本生活幸福的华侨华人的比例,与地震前相比,基本没有太大变化,但分析问卷结果,可以预测在不久的将来会出现留日学生减少、新华侨华人归国人数增多的现象,日本华侨华人社会将面临成长停滞或规模萎缩的可能.
