The dead body of a 44-year-old woman, previously known for depression and alcoholism, has been discovered at her place of residence by her husband. A forensic autopsy has been carried out. The results indicated unspecific histological lesions (alveolar oedema, liver steatosis and interstitial nephritis) but did not reveal any apparent cause of death. Several boxes of medicines have been found near the body, justifying a toxicological analysis. This has been performed on peripheral blood and urine samples using liquid chromatography with diode array and mass spectrometric detections, in conjunction with gas chromatography coupled with mass spectrometry. Ethanol has been found (1.24 g/L in blood, 2.63 g/L in urine and 1.33 g/kg in gastric content), as well as therapeutic concentrations of meprobamate (14.1mg/L) and low concentrations of nordazepam (0.12 mg/L) in blood. On the other hand, particularly high levels of labetalol, a widely used beta-blocker, have been found both in blood (1.7 mg/L) and urine (20.2mg/L), which led us to measure labetalol levels in available viscera samples (liver, heart, kidney, and lung) and gastric content. Measured concentrations were 14.2 microg/g, 7.8 microg/g, 5.4 microg/g, 5.2 microg/g and 31.1 microg/g, respectively. We describe here the first report of a fatal intoxication attributed to labetalol that is linked to its acute toxicity, with tissue distribution of this beta-blocker. 相似文献

This article reviews the application of metal-containing nanoparticles and nano-structured particles to fingermark detection. This area of research is attracting significant interest as advances in nanoscience are being incorporated into the field of forensic fingermark detection. Although more research is needed before some of the techniques presented can be implemented in routine casework, nanotechnology is likely to play a major role in the future to deliver more selective and more sensitive ways to detect and enhance fingermarks. 相似文献

In the present age of heightened emphasis on counter terrorism, law enforcement and forensic science are constantly evolving and adapting to the motivations and capabilities of terrorist groups and individuals. The use of biological agents on a population, such as anthrax spores, presents unique challenges to the forensic investigator, and the processing of contaminated evidence. In this research, a number of porous and nonporous items were contaminated with viable anthrax spores and marked with latent fingermarks. The test samples were then subjected to a standard formulation of formaldehyde gas. Latent fingermarks were then recovered post decontamination using a range of methods. Standard fumigation, while effective at destroying viable spores, contributed to the degradation of amino acids leading to loss of ridge detail. A new protocol for formaldehyde gas decontamination was developed which allows for the destruction of viable spores and the successful recovery of latent marks, all within a rapid response time of less than 1 h. 相似文献

From 1993 to 2008, criminal investigations were conducted in the western part of Switzerland with special attention to blowfly and flesh fly species in order to estimate the post-mortem interval when requested by the police authorities. Flesh flies were found in only 33 cases out of 160. Five species of the genus Sarcophaga were identified (S. africa, S. argyrostoma, S. caerulescens, S. similis and S. sp.). The main species found on corpses (larval stage) was S. argyrostoma. The thermal constant (K) calculated for this species in Switzerland is 380.6 ± 16.3 (mean ± S.D.) degree-days. With the exception of S. caerulescens, found three times in the larval stage on corpses, the three other species are of minor forensic importance. S. argyrostoma is found during summer and indoors. This species colonises dead bodies, usually the same day as blowfly species, and it could be used to estimate the post-mortem interval. Other species are discussed in the light of current knowledge on their biology and ecology. It is recommended that voucher material be deposited in a museum, allowing further studies by relevant specialists, thereby helping investigators and avoiding misidentifications. 相似文献

Traditional approaches to fighting poverty have yielded unsatisfactory results in some African countries, and have been positively damaging in others. Economic growth and social expenditure on the part of both national governments and international donors have been ineffective in some countries, while in others they have exacerbated poverty. The author considers that this is due to the absence of participatory governance. From a theoretical perspective, support for participatory governance stems from Amartya Sen's approach to understanding poverty, which conceptualises poverty as a lack of capabilities, leading to social exclusion. The lack of such governance has led to the failure of traditional approaches in the fight against poverty in sub-Saharan Africa. Finally, the author proposes a tool for assessing the quality of governance, and its application in Cameroon. 相似文献

The present review examined the predictors of job stress in correctional officers and marked the first meta-analysis of this topic area. Twenty studies were selected for inclusion, producing 191 individual effect size estimates. Overall, the findings revealed that work attitudes (i.e., participation in decision-making, job satisfaction, commitment, and turnover intention) and specific correctional officer problems (i.e., perceived dangerousness and role difficulties) generated the strongest predictive relationships with job stress. Furthermore, both favorable (i.e., human service/rehabilitation orientation and counseling) and unfavorable (i.e., punitiveness, custody orientation, social distance, and corruption) correctional officer attitudes yielded moderate relationships with job stress, with the country of study emerging as a critical moderating variable. The weakest correlates of job stress were demographic variables and job characteristics (e.g., security level). The implications of these findings are discussed and directions for future research are provided. 相似文献
