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

A large proportion of perinatally HIV-infected (PHIV) children are becoming adolescents and exploring their sexuality. This
study explored the prevalence of sexual behaviors (kissing, touching, engaging in oral sex, or having vaginal/anal intercourse)
in a sample of predominantly ethnic minority youths (N = 339; 54.1% Black and 30.4% Latino; 51% female; ages 9–16) perinatally exposed to HIV (61% HIV+). Using logistic regression,
we tested the association between sexual behavior and HIV status, demographic characteristics, and peer influences regarding
sexual behavior. PHIV youth were less likely to be sexually active. Among sexually active youth, PHIV youth were more likely
to engage in touching behavior than HIV-negative youth and were less likely to engage in penetrative sex. Youths reporting
that a greater number of their peers believed that sexually active boys were “cool” or “popular” were more likely to report
sexual behavior. The association between sexual behavior and peers believing sexually active girls were “cool” or “popular”
varied by age, gender, and HIV status. Furthermore, friends’ sexual activity was associated with sexual intercourse. Prevention
programs should strengthen messages addressing peer norms regarding sexuality, as well as address specific issues related
to adolescent HIV.

Abstract: This article describes a reform to improve delivery of state‐funded employment services in the province of Quebec. It is based on a six‐year field study conducted during the reform process and presents the reform's objective, the way it was implemented, and some of the lessons learned during the reform process. This study focuses on three points: the key steps that led to the implementation of an output‐based contracting system between the state and non‐profit organizations; why the process of implementing private‐sector practices was unexpectedly long and complex; and the side‐effects associated with the reform. 相似文献
