The Application of Flow Cytometry as a Rapid and Sensitive Screening Method to Detect Contamination of Vitreous Humor Samples and Avoid Miscalculation of the Postmortem Interval 下载免费PDF全文
Cristina Cordeiro M.Sc. Rafael Seoane Ph.D. Ana Camba M.Sc. Elena Lendoiro M.Sc. María S. Rodríguez‐Calvo Ph.D. Duarte N. Vieira Ph.D. José I. Muñoz‐Barús Ph.D. 《Journal of forensic sciences》2015,60(5):1346-1349
Research into maximizing the speed, precision, and reliability of estimating the postmortem interval (PMI) has been a recurring object of investigation and methodologies based on the vitreous humor (VH) have provided good results. However, contamination from causes not readily apparent, such as blood, can occur, and thus lead not only to an erroneous estimation of PMI, but also interfere with the correct identification of other substances in the VH. We have developed a flow cytometry method which quantifies blood contamination and is able to detect erythrocytes in 1:750,000 dilution of contaminated VH which affects the results of hypoxanthine. It is an improvement on the previous more complex mass spectrometry method, being faster, more sensitive, and readily available. As such, it could be proposed for the rapid screening of appropriate samples by detecting and eliminating blood contaminated samples from PMI estimation. 相似文献

The last decade has seen an unprecedented increase in conflict management activities in Africa by international organisations. This has been accompanied by a flurry of academic publications and of policy reports that stress the comparative advantages at the legal and operational levels of regional and other intergovernmental organisations. The article assesses this dominant favourable view by examining the role of the Commonwealth, the Francophonie and the CPLP in Africa. Traditionally regarded as cultural organisations, they have gradually extended their profile to include a security mandate. Drawing from fieldwork and an extensive review of the literature, the article presents the first comparative study of the conflict management activities of these organisations in Africa. 相似文献

Can there be a non-reductivist, source-based explanation of the use of normative language in statements describing the law and legal situations? This problem was formulated by Joseph Raz, who also claimed to have solved it. According to his well-known doctrine of ‘detached’ statements, normative legal statements can be informatively made by speakers who merely adopt, without necessarily sharing, the point of view of someone who accepts that legal norms are justified and ought to be followed. In this paper I defend two theses. I argue, first, that the notion of a detached statement cannot be made to work, and that Raz’s problem is thus not thereby solved. But the problem itself, I also suggest, is a false one. 相似文献

This article debates and defends the lawfulness of a randomised controlled trial of compulsory outpatient treatment under the mental health legislation for England and Wales. The trial is designed to compare the outcomes for patients of their treatment under the new Community Treatment Order (CTO) regime with their treatment under the older leave scheme - the two main forms of compulsory care in the community now authorised by the revised Mental Health Act 1983. The methods for the trial involve the random allocation of some patients between the two schemes, when they are considered by their Responsible Clinicians to be eligible for some form of compulsory outpatient care. The main question we consider is the lawfulness of that aspect of the methods. Can a carefully selected group of patients be allocated at random between the two regimes to permit an evaluation to proceed? Or would that involve some departure from the decision-making criteria specified by law? We argue that a group of patients can be identified who meet - simultaneously - the tests for treatment under both the CTO and the leave schemes. Those patients could then be allocated lawfully to treatment under either scheme. This opens the door, we argue, to their random allocation between the two schemes for the purposes of the research. In reaching this conclusion, we explain the methods and aims of the trial and closely compare the respective features of the leave and CTO regimes. 相似文献

Several European countries of immigration have recently introduced citizenship ceremonies on either a mandatory or voluntary basis. Yet, little is known about how the target group for such ceremonies experiences them, and to what extent citizenship ceremonies achieve their goals of contributing to a greater sense of belonging. In this article, we analyse interviews with more than 50 newly naturalised Norwegian citizens about their reasons to attend or to not attend the voluntary ceremony in Norway. We find little resistance to the idea of citizenship ceremonies. For some participants, the ceremony seems to have great emotional value; the majority, however, chooses not to participate. 相似文献

ABSTRACT: The incidence of rape has increased, especially in metropolitan areas, such as the city of São Paulo. In Brazil, studies about it have shown that the majority of this type of crime is committed by the relatives and persons close to the victim. This has made the crime more difficult to be denounced, as only 10% of the cases are reported to competent police authorities. Usually, cytological exams are carried out in sex crime investigations. The difficulty in showing the presence of spermatozoa is frequent, but it does not exclude the presence of male DNA. The absence of spermatozoa in material collected from rape victims can be due to several factors, including the fact that the agressor suffers from azoospermia. This condition can be the result of a successful vasectomy. As the majority of DNA in the ejaculation sample is from spermatozoa, there is much less DNA to be analyzed. This study presents the application of Y‐STRs (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, and DYS393) in DNA analysis of sperm samples from 105 vasectomized men. The study demonstrated a great variation in DNA concentration. DNA extraction and amplification was possible in all sperm samples even in the absence of spermatozoa. The same profile was observed, for each individual, from DNA extracted from blood, pre‐ and postvasectomy semen samples. The use of markers specific for Y chromosome in sex crime cases, especially in the absence of spermatozoa, is very important, mainly because in most situations there is a small quantity of the agressor's DNA in the medium and a large quantity of the victim's DNA. 相似文献

Abstract: Nonpenetrating chest trauma with injury to the heart and aorta has become increasingly common, particularly as a result of rapid deceleration in high-speed vehicular accidents, over the past 2–3 decades. The high mortality rate of cardiac injuries and possible late onset complications make blunt cardiac injuries an important challenging point for legal medicine. One hundred and ninety cases with blunt cardiac injuries in a period of 3 years were analyzed retrospectively in terms of patterns of cardiac injury, survival times, and demographic profiles of the cases in this study. 相似文献

The anti-corruption activity of the 1990s is characterized by the rise of new players, such as specialized anti-corruption
bodies. Anti-corruption agencies (ACAs) are public bodies of a durable nature, with a specific mission to fight corruption
and reducing the opportunity structures propitious for its occurrence in society through preventive and/or repressive measures.
Independently of their format and powers, ACAs encounter various constraints to their mandate, which explains the meagre results
obtained by some of them. This introductory paper tries to understand the rise, future, and implications of this new kind
of “integrity warrior” and to locate them in the evolving doctrine of corruption control. The objective of this edited volume
is to re-launch the debate on ACAs as the most innovative feature of the anti-corruption movement of the last two decades. 相似文献
