Abstract: In the present study, ultrastructural analysis of mitochondrial deposits (black dots within mitochondria) as a method for the detection of early acute myocardial infarction (AMI) was evaluated. In 24 patients with AMI and six controls, analysis was performed in the heart of infarcted patients and noninfarcted controls. In the infarction area in lactate dehydrogenase (LDH)‐diagnosed AMI, the percentage of positive mitochondria was significantly higher compared to corresponding heart tissue in control patients and compared to noninfarcted areas within these patients. Also in patients with a clinically diagnosed AMI but no LDH decoloration, a significant higher percentage of positive mitochondria was found in the left ventricle compared to controls and noninfarcted areas. In patients with AMI, an increase in mitochondria with deposits was found in the infarction area compared to controls and noninfarcted tissue within the same patient, suggesting that electron microscopical changes in mitochondria can be used for the diagnosis of AMI less than 3 h old. 相似文献

Archaeological remains can provide concrete cases, making it possible to develop, refine or validate medico-legal techniques.In the case of the so-called ‘Joan of Arc's relics’ (a group of bone and archaeological remains known as the ‘Bottle of Chinon’), 14 specialists analysed the samples such as a cadaver X of carbonised aspect: forensic anthropologist, medical examiners, pathologists, geneticists, radiologist, biochemists, palynologists, zoologist and archaeologist. Materials, methods and results of this study are presented here.This study aims to offer an exploitable methodology for the modern medico-legal cases of small quantities of human bones of carbonised aspect. 相似文献

Criminal behavior of parents substantially affects the criminal behavior of children. Little is known, however, about how
crime is transmitted from one generation to the next. In order to test two possible explanations against each other, we pose
the question whether the timing of the criminal acts of fathers is important for children’s chances of committing crime. Static
theories predict that it is the number of delinquent acts performed by fathers that is important, and that the particular
timing does not affect the child’s chance of committing crime. Dynamic theories state that the timing is important, and children
have a greater chance of committing crime in the period after fathers have committed delinquent acts. Results show that the
total number of convictions of a father is indeed very important, but also the exact timing is key to understanding intergenerational
transmission of crime. In the year a father is convicted the chance his child is also convicted increases substantially and
it decays in subsequent years. This decay takes longer the more crimes father has committed. Our results show that some of
the assumptions of the static theories at least need to be adjusted. 相似文献

The entry into force of the Lisbon Treaty has suspended discussions over the release of a EU PNR processing system. Plans to introduce an intra-EU PNR processing system initiated since 2007, although strongly supported by the Commission and the Council, did not bear fruit before the ratification of the Lisbon Treaty and the, institutional, involvement of the Parliament. While discussions have been suspended since October 2009 and most probably a new draft proposal will be produced, it is perhaps useful to present in brief the proposal currently in place so as to highlight its shortcomings for European data protection and suggest ways individual protection may be strengthened in future drafts. 相似文献

Spanish legislation against trafficking in human beings: punitive excess and poor victims assistance
Francisco Javier De León 《Crime, Law and Social Change》2010,54(5):381-409
The article seeks to provide a perspective of human trafficking as one of the fastest growing criminal activities of the last
few years in the area of organised crime and one that affects human beings’ most basic rights. In the main, the response to
the problem has been its criminal prosecution, but without tackling the issues of need that underlie this conduct and which
the traffickers take advantage of to abuse, assail and exploit the people they traffic. In this context, the evolution of
Spanish legislation in terms of the criminalisation of this problem has made it one of the most repressive, although there
is no clear evidence of its effectiveness. This punishment, which covers a wide range of criminal conducts, has not however
been accompanied by any policies to support and integrate the victims of trafficking, which has led to a large number of victims
being subjected to slavery who, in the majority of cases, fall under the control of the trafficking networks again. 相似文献

Angola is located in the African continent, in the area of southern Africa and has a population of approximately 14 million inhabitants. The Angola population has origin from Occidental and Southern Bantu people that came from the great lakes region, creating the most ever known African migration of our days.Allele frequencies for the 15 STRs loci in the AmpFlSTR Identifiler kit (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, HUMTH01, D13S317, D16S539, D2S1338, D19S433, HUMVWA, TPOX, D18S51, D5S818, HUMFIBRA/FGA and including the segment of the X-Y homologous gene amelogenin) were studied for Angola population.The genotype frequency of the 15 STR loci showed no significant deviations from Hardy–Weinberg equilibrium expectations and great values for the combined power of discrimination and combined power of a priori exclusion validate the application of these markers in forensic genetics. Comparative analyses between Angola population data and other relevant population database from Africa, Europe and American are presented. 相似文献

There is limited research on the gendered impacts of drug policies in Canada, despite the fact that women, Indigenous women in particular, are the country’s fastest growing prisoner population, with many incarcerated for drug-related crimes. This article highlights the results of a larger qualitative study with former prisoners in Ontario and community and medical experts from across the country. Focusing on the women research participants, we consider the lack of adequate and culturally-relevant substance use and harm reduction programming in federal prisons, and suggest a reformulation of Canada’s punitive drug policies toward a health and social welfare approach. 相似文献

Soil vestiges might provide information about a crime scene. The Rietveld method with X‐ray diffraction data (RM‐XRD) is a nondestructive technique that makes it possible to characterize minerals present in the soils. Soil clays from the metropolitan region of Curitiba (Brazil) were submitted to DCB treatment and analyzed using XRD with CuKα radiation in the step‐scan mode (0.02° 2θ/5 s). The GSAS+EXPGUI software was used for RM refinement. The RM‐XRD results, together with the principal component analysis (PCA) (52.6% total variance), showed the kaolinite predominance in most analyzed samples and the highest quartz contents in “site 1.” Higher anatase, and gibbsite and muscovite contents influenced discrimination, mainly in “site 3” and “site 1,” respectively. These results were enough to discriminate clays of four sites and two horizons using a reduced amount of sample showing that the technique can be applied to the investigation into soil vestiges. 相似文献

Soil traces are useful as forensic evidences because they frequently adhere to individuals and objects associated with crimes and can place or discard a suspect at/from a crime scene. Soil is a mixture of organic and inorganic components and among them soil clay contains signatures that make it reliable as forensic evidence. In this study, we hypothesized that soils can be forensically distinguished through the analysis of their clay fraction alone, and that samples of the same soil type can be consistently distinguished according to the distance they were collected from each other. To test these hypotheses 16 Oxisol samples were collected at distances of between 2 m and 1.000 m, and 16 Inceptisol samples were collected at distances of between 2 m and 300 m from each other. Clay fractions were extracted from soil samples and analyzed for hyperspectral color reflectance (HSI), X-ray diffraction crystallographic (XRD), and for contents of iron oxides, kaolinite and gibbsite. The dataset was submitted to multivariate analysis and results were from 65% to 100% effective to distinguish between samples from the two soil types. Both soil types could be consistently distinguished for forensic purposes according to the distance that samples were collected from each other: 1000 m for Oxisol and 10 m for Inceptisol. Clay color and XRD analysis were the most effective techniques to distinguish clay samples, and Inceptisol samples were more easily distinguished than Oxisol samples. Soil forensics seems a promising field for soil scientists as soil clay can be useful as forensic evidence by using routine analytical techniques from soil science. 相似文献

In anthropological and legal literature, the phenomenon termed ‘legal pluralism’ has been interpreted as a co-presence of legal orders which act in relation to their own ‘levels’ of referring ‘fields’. The Afghan normative network is generally described in terms of pluralism, where different normative systems such as customs, shari’a (Islamic law), state laws and principles deriving from international standard of law (e.g., human rights) coexist. In order to address the crucial question of access to justice, in this article, I stress the category of legal pluralism by introducing the hypothesis of an inaccessible normative pluralism as a key concept to capture the structural injustices of which Afghans are victims. Access to justice can be considered a foundational element of every legal project. Globally, the debates concerning the diffusion and application of human rights develop at the same time ideologically, politically, and pragmatically. Today in Afghanistan, these levels are expressed in all their complexity and ambivalence. It is therefore particularly significant to closely observe the work done by the Afghanistan Independent Human Rights Commission and to discuss the issue of human rights by starting from a reflection on what might be defined a socio-normative condition of inaccessibility. 相似文献
