Analytical Challenge in Postmortem Toxicology Applied to a Human Body Found into a Lake after Three Years Immersion 下载免费PDF全文

The body of a 30‐year‐old woman was found in Como lake at a depth of about 120 meters in her own car after 3 years of immersion. The aim of this study was to evaluate psychoactive drugs as well as alcohol biomarkers in biological matrices. The following analyses were initially performed: GC‐MS systematic toxicological analysis on biological fluids and tissues; GC‐MS analysis of drugs of abuse on pubic hair; direct ethanol metabolite determination in pubic hair by LC‐MS/MS. After 7 years, the samples, that had been stored at ?20°C, were re‐analyzed and submitted to an LC‐MS/MS targeted screening method, using multiple reaction monitoring mode. These analyses detected citalopram (150–3000 ng/mL), desmethylcitalopram (50–2300 ng/mL), clotiapine (20–65 ng/mL), and ethyl glucuronide (97 pg/mg). The methods showed an acceptable reproducibility, and the concentrations of citalopram and desmethylcitalopram calculated through the two analytical techniques did not significantly differ in biological fluids. 相似文献

The challenge of complex social issues drives the need for data systems that can connect information across multiple service delivery systems. Integrated data systems provide significant value for needs assessment, program planning, policy decision making, and collective impact evaluation across a range of social issues. This case study describes a mature county‐based integrated data system. The case study has three aims: (1) to highlight the value of integrated data systems to research, (2) to outline common challenges that such initiatives face, and (3) to present several ongoing considerations for the field that could inform policy recommendations to facilitate the use of integrated data. The authors present examples from the experience of developing this integrated data system, including involvement in the design and evaluation of the first county‐level social impact bond. The case study highlights the benefits and limitations of integrated data use in research and the potential to advance evidence‐based social decision making. 相似文献

This survey reviews the current state of the economic literature, assessing the impact of transport investments and policies on growth, inclusion, and sustainability in a developing country context. It also discusses the specific implementation challenges of transport interventions in developing countries. 相似文献

Guantánamo Bay is almost unanimously seen as an exceptional space inhabited by ‘bare life’. This article unpacks the double rendering of the exception in Carl Schmitt's work and argues that the conceptualisation of the exception in The Nomos of the Earth can help us understand the form of exception that is at work in the ‘war on terror’. The nomos as the junction of order and orientation appears as a way of closing off the space of political decision from Schmitt's earlier concept of the political. The constitution of order is no longer dependent upon the sovereign decision on the exception, but upon the division and appropriation of space, upon the geopolitics of uncontested spatialisations and a philosophy of concrete life. Therefore, Guantánamo will be exposed not as a singular and exceptional occurrence, but as symptomatic of the transformation of law. Law is moulded onto the order of what is; it is sustained by the situational characteristics of spaces and people at a distance from the contingency of sovereign decisions. 相似文献
