Trace Evidence Potential in Postmortem Skin Microbiomes: From Death Scene to Morgue

Microbes can be used effectively as trace evidence, at least in research settings. However, it is unknown whether skin microbiomes change prior to autopsy and, if so, whether these changes interfere with linking objects to decedents. The current study included microbiomes from 16 scenes of death in the City and County of Honolulu and tested whether objects at the scenes can be linked to individual decedents. Postmortem skin microbiomes were stable during repeated sampling up to 60 h postmortem and were similar to microbiomes of an antemortem population. Objects could be traced to decedents approximately 75% of the time, with smoking pipes and medical devices being especially accurate (100% match), house and car keys being poor (0%), and other objects like phones intermediate (~80%). These results show that microbes from objects at death scenes can be matched to individual decedents, opening up a new method of establishing associations and identifications.     

法治建设对民营企业发展的价值探析

在党的第十九次全国代表大会上,民营企业一词,被首次写入全国党代会报告。近来,习近平总书记还主持召开了民营企业座谈会。在第十三届全国人民代表大会第二次会议上,民营企业的发展也成为关注的热点话题。目前,民营企业得益于国家的鼓励支持、党的方针政策领导,逐步发展成为非常重要、不可或缺的市场主体,也是非公有制经济的核心力量。这个过程中,难免会有内部与外部的阻碍。在依法治国的大环境下,法治已是趋势,而对于民营企业来说,并没有具体的法律法规给予指导。因此,无论是内部环境的规整还是外部环境的保护都要求在法治建设上给予民营企业明确方向和法律保障。     

Psychophysiological Responses of People with Psychopathic Tendencies to the Concealed Information Test

This study was designed to investigate differences in psychophysiological responses among individuals with psychopathic tendencies. A total 40 students were participated and were divided into two groups based on Levenson Self‐Report Psychopathy Scale (LSRP) scores: a high psychopathic tendency group selected from the top 5% of LSRP scores, and a low psychopathic tendency group selected from the bottom 5% of LSRP scores. All participants were instructed to perform a mock crime and complete the concealed information test (CIT). Results indicate that significant differences between crime‐relevant questions and irrelevant questions were observed for respiration line length and skin conductance response in both groups, but heart rate did not significantly differ between groups. There were no differences in psychophysiological responses between the groups. In conclusion, CIT was found to be an effective method for detecting crime‐relevant information in individuals with psychopathic tendencies.     

固相微萃取在苯丙胺类毒品分析中的应用

固相微萃取(solid phase microextraction, SPME)作为一种新型样品前处理技术已受到广泛关注。由于SPME集采样、萃取、浓缩、进样于一体,克服了传统样品前处理技术步骤繁琐、耗时耗力、所需样品量大等诸多缺点,因此在对生物样品中毒品等目标物的分析中具有巨大的应用潜力。本文以纤维SPME技术为例,综述了该技术在苯丙胺类毒品分析中的研究进展,并对其发展方向进行了展望。

武汉汉族人群D20S85和D6S477基因座遗传多态性调查

目的对武汉地区280名汉族无关个体的D20S85和D6S477位点遗传多态性进行调查,研究其在法医学检验中的应用价值。方法应用PCR和PAGE技术进行分型检验。结果分别检出10个、9个等位基因,获得各等位基因在该地区汉族人群分布频率,基因型频率分布符合Hardy-Weinberg平衡。两位点的DP值分别为0.9085、0.9127。结论D20S85和D6S477是法医学中重要的遗传标记。
