人体组织ABO血型检测方法的研究

探讨人体组织ABO血型检测方法。对已知ABO血型尸体的不同组织,用红细胞粘连试验、吸收—抑制试验和吸收－解离试验进行ABO血型测定。12例尸体的16种组织中均检出与尸体血痕相同的ABH物质。对不同温度保存的组织块进行ABH物质检测的结果显示,4℃保存的组织ABH物质的检出时间长于室温,空腔脏器的检出时间短于实质脏器。三种方法中,红细胞粘连试验简单易行,适用于基层单位,吸收－抑制试验用于组织块的测定时优于吸收－解高试验。     

VNTR D17530位点多态性在亲子鉴定中的应用

运用微量热启动PCR技术,对20例正常家系的遗传学分析,证实D17530位点的遗传符合孟德尔遗传规律,表现为简单的共显性遗传。同时,对100例亲子鉴定案例进行回顾性分析研究,证明D17S30位．在多态性可应用于我国法医学亲子鉴定。根据D17S30位点基因频率估算的排除概率（74．04％）与其实际排除能力（80．00％）无显著差异。在15倒排除亲子关系的案例中,有2例由D17S30位点单独取得排除证据。D17S30位点是法医学上有重要意义的遗传学标记,可用于亲子鉴定。

The Plutocracy That Is U.S. Democracy

The U.S. doesn't have democracy, it has politics. Democracy is about serving the people, giving them what they want and improving their lives. China doesn't have career politicians, it has bureaucrats. Trained and skilled administrators who are elected from the bottom and selected from the top, but only if they are good enough. If they don't measure up, they lose their job.     

Neuropsychological,Psychological, and Vocational Assessment of High Achievers in a Medicolegal Context

High achievers are a unique subset of persons referred for neuropsychological and psychological assessments in medicolegal contexts, including personal injury, disability, and workers’ compensation cases. Literature in this area is limited and poorly integrated, and neither a conceptual model nor best evidence-informed practices for the assessment of high achievers in the medicolegal context have yet emerged. Construct and methodological issues also hamper the ability of assessors to accurately and fairly assess this specialist group, which is particularly troubling in high-stakes forensic assessments. This paper reviews the current methodological issues involved in the assessment of high achievers and proposes an integrated, multimethod assessment model based on a particular vocational group, namely that of business leaders and entrepreneurs, that draws from available empirical research in different fields of psychological inquiry.     

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.     

Measuring the impact of fair trade on development

This study of the impact of fair trade relies on new field data from coffee and banana co-operatives in Peru and Costa Rica, including a detailed assessment of its welfare effects by comparing FT farmers with non-FT farmers as a benchmark. Attention is focused on three major effects: (a) direct tangible impact of FT arrangements on the income, welfare, and livelihoods of rural households; (b) indirect effects of fair trade for improving credit access, capital stocks, investments, and attitudes to risk; and (c) institutional implications of fair trade for farmers' organisations and externalities for local and regional employment, bargaining, and trading conditions. Although direct effects in terms of net income remain fairly modest, important benefits are found to include capitalising farmers and strengthening their organisations.

Microwave-assisted extraction and differential scanning calorimetry in the chemical identification of sliming agents apprehended in the south region of Brazil

Over the past decades, consume of slimming agents considerably increased in several countries, including Brazil, due to weight-loss and stimulant properties. Since these drugs are controlled to prevent illicit and indiscriminate use, there is a parallel illegal market that uses the Internet and irregular pharmacies in order to distribute these formulations. Slimming agents produced by these illegal sources are known for being manufactured with little or none quality control resulting in uncertain and unknown formulations. For forensic purposes, apprehended pharmaceuticals have to undergo a process of chemical identification that can be difficult due to its complex matrix. In this sense, application of assisted energies in the extraction step such as microwave irradiation can be a promising method to increase the recuperation of the target molecules of the sample. Therefore, the aim of this research was to identify four slimming agents apprehended in Brazil by means of visual inspection, Fourier Transform Infrared Spectroscopy, Differential Scanning Calorimetry and Gas Chromatography – Mass Spectrometry. Moreover, the efficiency of solid-liquid extraction and microwave-assisted extraction was compared. It should be noted that our work was one of the few to use Differential Scanning Calorimetry and the application of microwave irradiation in the analysis of apprehended materials. Results showed that the majority of the samples was counterfeit being composed of one or several adulterants or contaminants. Initially, visual inspection resourcefully screened the slimming agents for possible signs of falsification, however it failed to detect fraudulent products that were very similar to veridical medicines. Sequentially, Fourier Transform Infrared Spectroscopy detected functional groups present in the samples while the presence or absence of the alleged active ingredients were successfully measured with Differential Scanning Calorimetry and, thus, providing a full chemical screening of the apprehended materials. Gas Chromatography- Mass Spectrometry confirmed the presence of adulterants such as caffeine, fluoxetine and phenolphthalein as well as contaminants such as sulfurol in the falsified samples. Finally, comparison of extraction procedures indicated that microwave-assisted extraction increased the recovery of compounds detected in chromatographic analysis to a greater extent than solid-liquid extraction.
