The authors evaluated the usefulness of the postmortem biochemical analysis of ionic ratios in different parts of the heart and their relation to cardiac damage caused by chest trauma, as observed by anatomopathologic study. Fifty-nine 59 cases were studied, selected from routine necropsies, and samples were taken from different sites of cardiac tissue. The cause of death was trauma in 40 cases and nontraumatic causes in 19 cases. The object of this study was to analyze the levels of Na+, K+, Ca+2, Mg+2, and Zn+2 in different zones of the heart, and the relationship between intracellular and extracellular ion ratios and the different causes of death and any anatomopathologic alterations observed. The biochemical tests revealed a possible relation between the ionic values and cause of death. Alterations in cell membrane permeability and corresponding modification of the ionic ratios were produced earlier than histologic alterations, which need longer to establish themselves whether or not they follow a traumatic process. 相似文献

Forensic pathologists may be asked to identify the ethnic group and gender of a cranium of unknown origin. An analysis of the maxillary sinus--its volume, shape, and dimensions in dried crania of different ethnic and gender groups (European and Zulu male and female)--was conducted to establish a new approach. A variation in maxillary sinus volume may mean a variation in anatomic landmarks between the groups. Ethnic and gender variations in the shape of the maxillary sinus of the crania were investigated. This research was further extended to predict the gender and ethnic group from an unknown cranium to make this research valuable to the fields of forensic pathology and anthropology. Helical, multislice computed tomography was performed using 1-mm coronal slices. The area for each slice was obtained by tracing the outline of each slice. The computed tomographic machine calculated a volume by totalling the slices for each sinus. Advanced computer methodology including a neural network was designed and applied to search for classification patterns in data. A discriminant analysis was performed to improve classification results. Ethnic and gender variations were found in the different groups, and the predictive role of the maxillary sinus in ethnic classification was established. It was found that European crania had significantly larger antral volumes than Zulu crania, and males had larger volumes than females. Dimensions of European sinuses were larger than those of Zulu sinuses. The medial antral wall of the sinus allowed for ethnic classification. The discriminant analysis allowed for a very successful 90% ethnic prediction, while gender prediction was ultimately 79%. The measurements taken and the formulae created in this research will be valuable to those in the field who are seeking to ethnically classify a cranium into one or another ethic group. This research aims to be an aid in identification, as well as a starting point for other scientific studies based on other ethnic groups. Perhaps its true value will lie in confirming ethnicity by adding to existing criteria. It must be noted that this classification is based on actual measurements and therefore eliminates the some of the subjectivity present in current methods of ethnic classification. 相似文献

This study examined the relationship between lifetime abuse and mental health among 126 African American women and 365 White women from a primary health care setting who participated in a telephone interview as part of a larger study. Seven types of childhood and adult intimate partner abuse were measured. Consistent with hypotheses, (1) lifetime abuse was associated with elevated levels of anxiety and depression, and (2) women who experienced childhood abuse were more likely to report adult partner abuse. African American and White women showed more similarities than differences in the associations between most abuse experiences and depression and anxiety, as well as types of childhood abuse. African American abused women reported more excessive jealousy by partners. Nonabused African American women reported higher levels of depression and anxiety than their White counterparts. Results are interpreted and discussed taking into account relevant social and cultural factors. 相似文献

This paper compares environmental policymaking in two Brazilian cities, Rio de Janeiro and Cubatão. It examines the formation of state-society synergistic interactions in the public policymaking process and their effect on long term sustainability of social mobilization. It concludes that whereas social capital can be constructed in the context of policymaking, it is critically dependent on a concerted effort from both state and society actors to build trust in their daily interactions. The Cubatão and Carioca River cases show that state-society synergy had little effect on the ability of the policy coalitions formed for pollution clean up to sustain themselves over time. Instead, there are indications that rather than a constraint, the flexible and informal nature of such coalitions may have been a critical factor in their ability to carry out policy successfully. 相似文献

Seventeen Y-chromosomal short tandem repeats (STRs), DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385ab, DYS437, DYS438, DYS439, GATA-H4, DYS448, DYS456, DYS458, DYS635 were typed in DNA samples from the Kalmyk population (n=99). The population is characterized by a high proportion of duplicated DYS19 alleles and deletions of the locus DYS448 on the background of the Central Asian haplogroup C*. AMOVA analysis reveals a close vicinity to Mongolian and Kazakh populations and large genetic distance to geographical neighbours from Russia, Ukraine and the Caucasus. 相似文献

It is a requirement that forensic DNA profiling evidence be accompanied by an estimation of its weight, in order that the court can assign an appropriate probative value to the evidence during legal proceedings. There are various models by which this estimation can be made, but each relies on approximations of the allele frequencies in the relevant population. It is also important to assess relevant population genetic features of the available data. This report provides allele frequencies and estimates of common population genetic parameters for the major sub-populations of the Northern Territory of Australia genotyped at 15 autosomal short tandem repeat (STR) loci. 相似文献

This article explores the political and strategic implications of Scottish Independence for existing transatlantic security arrangements. It examines the potential institutional, legal and political obstacles Scotland might face during the transition to independence and discusses the specific challenges in the area of security and defence, including the nuclear issue and the question of what form an independent Scottish Defence Force (SDF) would need to take to allow and facilitate integration in transatlantic security structures. It argues that a number of strategic and political issues could be mitigated in the course of negotiations between Edinburgh and London. Moreover, Scotland's geostrategic position and political orientation make it an important prospective partner in international security cooperation across the Eastern Atlantic, High North and North Sea, which suggests that an advanced partnership with NATO, and eventually full membership, seems like an option that is both politically viable and more likely than any scenario that predicts seeing an independent Scotland (IS) outside these structures. This challenges some of the main strategic and security political arguments against independence and thus seeks to spark a debate about the realistic options for Scotland should it become independent after 2016. 相似文献
