The postmortem diagnosis of acute myocardial infarction represents a current challenge for forensic pathologists, particularly when death occurs within minutes to a few hours after the ischemic insult. Among the adult population the single most important cause of sudden cardiac death (SCD) is the well-known atherosclerotic coronary artery disease, commonly asymptomatic or unrecognized. The recognition of early myocardial damage using routine hematoxylin and eosin (H&E) staining is possible only if death has occurred at least 6 hours after the onset of the ischemic injury. The usefulness of immunohistochemical markers to the diagnosis of early myocardial damage has been recently suggested because most of them can be visible even serologically as early as few minutes after the beginning of the symptoms. To evaluate the usefulness of plasma and cellular antigens, their distribution patterns have been studied among a group of 18 SCD cases in which a myocardial ischemia was strongly suspected. For the present study, 4 markers have been selected on the basis of their different diagnostic potential as follows: among the plasma markers the C5b-9 and fibronectin, among the cellular markers the myoglobin and cardiac troponin. The results show that only the study of multiple markers such as those selected can provide enough evidence of myocardial ischemia and/or necrosis, supporting the final diagnosis of SCD. No single immunohistochemical staining is ideal for diagnosing early myocardial ischemia but a set of markers can improve the ability of forensic pathologists to detect ischemic areas when no macroscopic or microscopic evidence of necrosis is available. However, the interpretation of data obtained in each individual cannot be isolated from the overall assessment of the factors (cardiopulmonary resuscitation and/or agonal artifacts) that can affect the expression of each marker. 相似文献

During the years 2004-2006, seven divers, who had deadly accidents, underwent post-mortem examination at the Institute of Legal Medicine of the University of Munich. The cause of death in all divers was drowning with typical pathomorphological findings. This should be regarded as separated to the triggering reason for drowning. The trigger for accident was established in four of seven cases by technical analysis and police investigation. High risk-taking, lack of technical service, and deficiency of dive equipment care were main reasons for death. We present two of these cases which showed several problems occurring concurrently. Autopsy always is necessary to look for indices for application of force or to exclude competitive reasons for death. 相似文献

Universities are a hotbed of alcohol consumption, which is a major contributor to campus crime. In the US, campus police are responsible for handling crimes on campus. Like municipal police, campus officers are afforded the power to make discretionary sanctioning decisions. The question for this paper is what affects those decisions? To explore that topic, data collected during ride-alongs with campus officers are analyzed. Campus officers explained their sanctions as being affected by nine factors. The findings suggest that influences on campus and municipal officers’ sanctioning decisions are largely similar. The paper concludes by discussing implications for future research. 相似文献

Personalist dictatorships make up an increasingly large proportion of the world's dictatorships. Moreover, they tend to be particularly resistant to democratization. Understanding the conditions that increase the likelihood of democratic transitions in personalist contexts, therefore, is critical for the study and practice of democratization in the contemporary era. This study argues that political party creation is a key factor. Though personalist dictators typically create parties to offset immediate threats to their power posed by the elite – and particularly the military – doing so encourages peaceful mass mobilization and a realignment of elite networks. These dynamics, in turn, enhance prospects of democratization. Using cross-national empirical tests that address the potential endogeneity of this relationship, we find support for the argument that personalist dictators who create their own political party are more likely to democratize than those who ally with a pre-existing party or rule without one. 相似文献

Generation Identity (GI) is at the centre of right-wing politics across Europe. Yet, it does not present itself as a right-wing organisation. In contrast, GI seeks to move from the margins into the centre of civil society. Based on the literature on transnational NGOs’ action repertoires and by situating the discourse of GI with respect to a traditional human rights TNGO, Amnesty International, my qualitative content analysis of the frames of both organisations shows that GI uses the vague language of human rights to formulate its radical right-wing positions in ways that sound familiar with accepted human rights claims. While using similar language, symbols, emotions and performances than Amnesty, GI at the same time promotes an exclusive understanding of human rights based on identity. This allows for a discretionary understanding and application of human rights and, hence, potentially challenges established human rights organisations such as Amnesty because the latter's ability to influence state actors relies on a powerful and strong transnational discourse of human rights as being non-negotiable, indivisible and non-transferable. 相似文献

This paper analyses the impact of a low-cost land certification programme on the productivity of female-headed households. The hypotheses tested in the paper emphasise on the interaction between the constraints that female-headed households face in terms of insecure land tenure, lack of productive resources and suboptimal land market participation, on the one hand, and the tenure security benefits of certification on the other. Our findings show that land certification has a positive effect on land market participation and productivity. Our analysis also suggests higher marginal effects of certification on female-headed households’ productivity, compared to the male ones. 相似文献

Violations of human rights in the context of a conflict have in recent years received an increasing amount of attention from the international media. Yet how such media attention influences conflict remains understudied and, a priori, uncertain. On the one hand, media coverage of human rights abuses may constitute “naming and shaming” that might temper hostilities. On the other hand, such coverage might spark intransigence and complicate negotiations among conflicting parties, thereby hindering rather than hastening peace. This article tries to adjudicate among these and other possibilities by exploring how media reporting on human rights abuses influences the development of conflicts. The analysis reveals that such reporting is associated with shorter conflicts and negotiated agreements between fighting parties. 相似文献

Renal Tubular Epithelial Vacuoles—A Marker for Both Hyperlipidemia and Ketoacidosis at Autopsy 下载免费PDF全文
Chong Zhou M.B. B.S. Lynette Moore F.R.C.P.A. Andrea Yool Ph.D. Alvis Jaunzems Roger W. Byard M.D. 《Journal of forensic sciences》2015,60(3):638-641
Review of 15 cases of nephrotic syndrome found that eight had significant hyperlipidemia with serum cholesterol levels ranging between 10.59 and 18.60 mmol/L (mean 12.88) and serum triglyceride levels between 2.30 and 9.92 mmol/L (mean 4.58); all of these cases displayed basal lipid vacuolization. Seven of the 15 study cases had normal–mild hyperlipidemia with serum cholesterol levels ranging between 4.71 and 7.54 mmol/L (mean 6.02) and serum triglyceride levels between 0.65 and 4.1 mmol/L (mean 1.57). Six of the seven cases had basal lipid vacuoles (86%). Of these, five cases were hyperlipidemic and one case had borderline hyperlipidemia with a serum cholesterol level of 4.71 mmol/L. Although hyperlipidemia was associated with renal tubular epithelial vacuolization, the vacuoles appeared morphologically different to those found in ketoacidosis. This study has shown that while hyperlipidemia in isolation may result in basal lipid vacuolization within renal tubular epithelial cells, the phenotype differs from that observed in ketoacidosis. 相似文献

When prisoners return to the community they often strive to obtain immediate employment. However, finding work after being released from prison is one of the major challenges returning prisoners face. With few employment prospects due to legal restrictions, discrimination from prospective employers, and multiple individual and community barriers offenders often end up accepting low-skilled work with little opportunity for growth. This qualitative study examines the job searching process for women residing in a community correction work-release facility. The researcher identified several barriers to securing employment, as well as many factors that facilitated the process. Sources of help, types of jobs secured, and experiences with stigma and discrimination are discussed. Implications for improving the job searching process for this population are discussed. 相似文献

Scholars agree that ideology affects judicial decision-making. We demonstrate that this proposition holds true even when the judiciary is independent of political control. Focusing on Italy (1983–2013), where the politicisation of the judiciary was an issue well before the entry of Berlusconi into politics, we estimate judicial orientations according to the support for factions within the National Judiciary Association. The results show that ideology affects trial court activity against deputies. As the support for left-wing factions increases, prosecutors are more likely to investigate right-wing parties. Conversely, as the share of right-leaning factions grows, investigations of moderate or rightist parties decrease. 相似文献
