The polymorphism of nine STR loci has been studied in a sample of 598 individuals from the population of Alagoas, Northeastern Brazil. Determination of the allele frequencies as well as of several commonly used statistics in forensic and paternity testing were defined. The most polymorphic loci were TH01 and D7S317. The exact test demonstrated that the nine loci analyzed in the population have no deviation from Hardy–Weinberg equilibrium (P>0.05). 相似文献

Previous research on the RAG color‐coded prioritization systems for the discovery of clandestine graves has not considered all the factors influencing the burial site choice within a GIS project. The goal of this technical note was to discuss a GIS‐based quantitative approach for the search of clandestine graves. The method is based on cross‐referenced RAG maps with cumulative suitability factors to host a burial, leading to the editing of different search scenarios for ground searches showing high‐(Red), medium‐(Amber), and low‐(Green) priority areas. The application of this procedure allowed several outcomes to be determined: If the concealment occurs at night, then the “search scenario without the visibility” will be the most effective one; if the concealment occurs in daylight, then the “search scenario with the DSM‐based visibility” will be most appropriate; the different search scenarios may be cross‐referenced with offender's confessions and eyewitnesses’ testimonies to verify the veracity of their statements. 相似文献

One of the most frequent causes of death in developed countries is sudden natural death (SND), which is the most common indication for medico-legal autopsies. Cardiac diseases are frequently detected among SND. Mitochondrial DNA (mtDNA) is easily damaged by reactive oxygen species, and it may cause dysfunction in tissues, leading to early events in cardiovascular disease. A specific mtDNA deletion of 4977 bp is associated to aging, myocardial dysfunction, and bioenergetic deficit. The potential link between mtDNA damage and SND has not been investigated before. Our aim was to evaluate the accumulation of the common mtDNA4977-deletion in cardiac muscle samples from autopsies of SND in adults (n = 14) in comparison to control samples from unnatural deaths (n = 12). Serial dilution-polymerase chain reaction method was performed to estimate the proportion of the total mtDNA harboring the mtDNA4977-deletion. Coefficient variation intra-assay was 8%, and inter-assay was 12%. MtDNA4977-deletion percentage was higher in samples obtained from victims of SND than in those from subjects who died of unnatural causes (p < 0.05). No differences in mtDNA4977-deletion were found between SND victims 39-51 years old, and no correlation was found between these samples and age, r = 0.30, p = 0.29 while it was significant among control samples, r = 0.68, p < 0.05. The association between mtDNA4977 deletion with SND victims might offer a tool to provide additional information to clarify complex SND investigations. 相似文献

This paper develops a model for the exchange rate in Brazil during the second half of the nineteenth century. The exchange rate discussion has a bearing in the sources of industrialization in Brazil. Two explanations stem from a primary export base. Whereas the ‘adverse shock argument’ links industrialization to unfavorable conditions in the external sector and exchange devaluations, the alternative approach views industrialization from the standpoint of the growth of income brought by the rise in exports. Those mechanisms are discussed. Also considered are the effects of monetary policy and the behavior of wages. The evidence shows that purchasing power parity is not enough to explain the exchange rate behavior, which clearly responded to coffee export revenues. 相似文献

This work evaluates cocaine purity and the concentration ranges of adulterants and inorganic constituents for 31 street cocaine samples seized in two different regions of Brazil from July 2008 to May 2010. Cocaine and adulterants, such as caffeine, lidocaine and benzocaine, were quantified by Gas chromatography–mass spectrometry (GC–MS), and the inorganic constituents were determined by Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) and ion chromatography (IC). The cocaine concentrations in the samples seized in the Amazonas state (AM samples) ranged from 154 to 978 mg g? 1, and these samples did not contain any of the adulterants studied. The cocaine concentrations in the samples seized in the Minas Gerais state (MG samples) ranged from 63.9 to 753 mg g? 1. Caffeine was the main adulterant found in 76% of the MG samples, ranging in concentration from 5.5 to 645.3 mg g? 1. Lidocaine was found in 66.7% of the MG samples, with concentrations ranging from 16.3 to 576.7 mg g? 1. Benzocaine was found in only one MG sample, at a concentration of 84.8 mg g? 1. Fourteen elements were identified by ICP-OES, and a wide variation was observed in the concentrations of Ca, Mg, Na, P, Al, Fe, Mn and Zn. Pearson Product–moment Correlations between the analytes allowed the constituents to be associated with the chemicals used in the manufacturing of cocaine and with some common diluents. The study of the purity of cocaine and the presence and concentration of adulterants and inorganic constituents is important because the latter can have deleterious effects on health. 相似文献

This paper aims to describe and evaluate a protocol for extraction of DNA (deoxyribonucleic acid) in formalinized tissues and embedded in paraffin for forensics genetic analysis. In outline the method is the removal of paraffin with an organic solvent in 0.3–0.5 mg of the sample of the tissue under study, followed by removal of formaldehyde, rehydration and soon after the extraction of genomic DNA. The extraction is achieved through the stages of cellular lysis, enzymatic digestion of proteins and DNA precipitation in ethanol medium. With the research we can conclude that even when the DNA is present in small quantities in conditions of extreme difficulties in its extraction, as formalinized tissues and embedded in paraffin, the technique of optimizing the extraction of DNA used both to organic extraction as Chelex, for use in the polymerase chain reaction (PCR), and possible the investigation of different samples of human tissue, biological samples, or was obtained under the conditions tested, a DNA with good quality and concentration. The samples were amplified for the mini-STRs loci using the product marketed in multilocus, using a methodology recommended by the supplier and validated for analysis of forensic DNA. Commercial kit was used MiniFiler from Applied Biosystems. The DNA fragments amplified by PCR showed that the extracted DNA had good amplification. 相似文献

This study uses five waves of the Indonesian Demographic Health Surveys to analyse decentralisation and geographical inequality in health services delivery. Accounting for unobserved community-level heterogeneity with random effects and correlated random effects models, we link facility-based birth delivery to the period of decentralisation and Indonesia’s major island groups using a pooled sample of 71,815 children. We also generate direct estimates of neonatal mortality from 1990 to 2007. The results show that the implementation of decentralisation has accorded with a marked expansion in both health service and outcome inequalities in Indonesia, at least with respect to neonates. Systemic funding failures for health and decision-space issues resulting from decentralisation are likely to have greater impact in disadvantaged regions where local capacity is weakest. The need to address these fundamental issues to reduce inequalities and improve general health outcomes appears supportable. 相似文献
