扩增X—Y同源Amelogenin基因内含子在性别鉴定中的应用研究

本文用一对针对X－Y同源的Amelogenin基因第一内含子的引物，于同一试管中分别扩增出针对于x和Y染色体的特异性DNA片段：106bp及112bp的PCR产物，经聚丙烯酰胺凝胶电泳后用银染法观察扩增结果，取得了满意的效果．对50pgDNA模板室温放置16年的血痕及单根毛发、烟头等检材均可得到明确的性别鉴定结果．本实验证明该方法简便、灵敏、可靠、特别适用于腐败降解检材的法医学性别鉴定．     

Bank security dye packs: synthesis, isolation, and characterization of chlorinated products of bleached 1-(methylamino)anthraquinone

Banknote evidence is often submitted after a suspect has attempted to disguise or remove red dye stain that has been released because of an anti-theft device that activates after banknotes have been unlawfully removed from bank premises. Three chlorinated compounds have been synthesized as forensic chemical standards to indicate bank security dye bleaching as a suspect's intentional method for masking a robbery involving dye pack release on banknotes. A novel, facile synthetic method to provide three chlorinated derivatives of 1-(methylamino)anthraquinone (MAAQ) is presented. The synthetic route involved Ultra Clorox bleach as the chlorine source, iron chloride as the catalyst, and MAAQ as the starting material and resulted in a three-component product mixture. Two mono-chlorinated isomers (2-chloro-1-(methylamino)anthraquinone and 4-chloro-1-(methylamino)anthraquinone) and one di-chlorinated compound (2,4-dichloro-1-(methylamino)anthraquinone) of the MAAQ parent molecule were detected by gas chromatography mass spectrometry (GC-MS), and subsequently isolated by liquid chromatography (LC) with postcolumn fraction collection. Although GC-MS is sensitive enough to detect all of the chlorinated products, it is not definitive enough to identify the structural isomers. Liquid-state nuclear magnetic resonance (NMR) spectroscopy was utilized to elucidate structurally the ortho- and para-mono-chlorinated isomers once enough material was properly isolated. A reaction mechanism involving iron is proposed to explain the presence of chlorinated MAAQ species on stolen banknotes after attempted bleaching.     

Treatment-Related Reductions in Disability Are Associated with Reductions in Perceived Injustice Following Treatment of Whiplash Injury

Emerging evidence suggests that perceived injustice is a risk factor for poor recovery outcomes in individuals with whiplash injuries. The present study examined the relative contributions of treatment-related reductions in pain severity, depressive symptoms, and disability in the prediction of reductions in perceived injustice in individuals with whiplash injury. The study sample consisted of 71 individuals (43 women and 28 men) who sustained whiplash injuries in motor vehicle accidents and who were enrolled in a treatment program designed to promote functional recovery following whiplash injury. For the purposes of this study, only individuals who scored above the risk threshold on a measure of perceived injustice were included in the study sample. Participants completed measures of pain severity, disability, depressive symptomatology, and perceived injustice prior to treatment and after treatment. Change scores were computed for study variables. The results revealed that reductions in pain severity and disability were correlated with reductions in perceived injustice. Regression analyses revealed that only reductions in disability contributed significant unique variance to the prediction of reductions in perceived injustice. Clinical and theoretical implications of the present findings are discussed.     

The Decline of Federalism and the Rise of Morality-Policy Conflict in the United States

Morality policies-such as those pertaining to abortion, capitalpunishment, gambling, gay rights, pornography, and sex education—generateconflict over core values. These policies tend to be technicallysimple, potentially salient to the general public, and involvehigher than normal levels of citizen participation. They are,therefore, highly susceptible to being thrust into the activephase of policymaking when an incongruity develops between publicopinion and public policy. The reservation of authority to thestates on these issues embodied in the Tenth Amendment to theU.S. Constitution allows for closer policy-opinion congruence,therefore stabilizing morality policy politics. However, recentfederal actions on a range of morality policies have thrustthese issues onto the active political agenda of the states.     

Risk assessment in offenders with intellectual disability: a comparison across three levels of security

In mainstream offender samples, several risk assessments have been evaluated for predictive validity. This study extends this work to male offenders with intellectual disabilities. Participants from high-, medium-, and low-security settings, as well as community settings, were compared on a range of risk assessments. The Violence Risk Appraisal Guide, HCR-20-Historical Scale, the Risk Matrix 2000-C (combined risk), and the Emotional Problems Scales-Internalising discriminated between groups, with participants from high security having higher scores than those in medium security, who had higher scores than those in the community. The Violence Risk Appraisal Guide, all HCR-20 scales, the Short Dynamic Risk Scale, and the Emotional Problems Scales (Internalising and Externalising) showed significant areas under the curve for the prediction of violence. The Static-99 showed a significant area under the curve for the prediction of sexual incidents. The discussion reviews the value of these various scales to intellectual disability services.
