Tissue concentrations of MDMA and its metabolite MDA in three fatal cases of overdose

The recreational use of amphetamine derivatives has become increasingly popular in our country in past recent years. Their use is especially common among young people participating in dance parties known as "raves." As a direct consequence of their increased use, the number of fatal cases in which these compounds have been involved have increased dramatically since the second half of the last decade. In our laboratory, we have registered 25 cases related to amphetamine derivatives use since 1996. Three of them were deeply studied and the results obtained are presented in this paper. This information may be useful for the interpretation of the results obtained in toxicological analysis in the cases in which death may be attributed to MDMA use.     

Glucose and lactate in vitreous humor compared with the determination of fructosamine for the postmortem diagnosis of diabetes mellitus

Diabetes mellitus is a chronic metabolic illness responsible for a great number of deaths. In postmortem diagnosis, because of the difficulty involved in interpreting blood glucose levels and relatively nonspecific pathologic features, biochemical markers in vitreous humor are useful. The aim of this study was to compare the results obtained for the combined determination of lactate and glucose with fructosamine levels recorded in the vitreous humor of two diagnostic groups (one diabetic and the other nondiabetic). The authors intended to ascertain the capacity of different markers measured in vitreous humor to diagnose diabetes mellitus. Fifty-one cadavers (mean age, 58.7 years; standard deviation, 17.09) were studied. The mean postmortem interval was 16.4 hours (standard deviation, 9.05). Cases were assigned to two diagnostic groups according to whether they were previously diagnosed as either diabetic or nondiabetic. Statistically significant differences for glucose, fructosamine, and the sum values of glucose and lactate were found between the two diagnostic groups. The highest levels were obtained in the group of cases with a previous diagnosis of diabetes mellitus. After the comparison of receiver operating characteristic curves, the sum values of glucose and lactate in vitreous humor is a better predictor of antemortem diabetes mellitus than the fructosamine.     

The European Union and Latin America: ‘Transformative power Europe’ versus the realities of economic interests

Relations between the European Union (EU) and regional subgroups in Latin America (Mercosur, the Andean Community and Central America) are clear examples of ‘pure interregionalism’ and provide evidence of the EU's active promotion of regional integration. Within the context of these cases, this article explores what type of international power the EU wields, how interregionalism is embedded in that power, and how it is deployed. Combining strands of literature on EU–Latin American relations, interregionalism, EU external policy and power provides a framework within which interregionalism can be understood as an important normative and practical tool for the EU's external power projection. Drawing on official documentation and interviews with key individuals, the paper highlights the EU's articulation of power in interregional relations and reflects upon its mixed success. It concludes that, while imperial qualities and aspirations can be observed in the EU's penchant for interregionalism, the transformative power of the EU remains limited.     

Genetic variation of 15 STR autosomal loci in the Maracaibo population from Venezuela

Allele frequencies for 15 short tandem repeats (STRs) autosomal loci (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818 and FGA, included in the AmpFLSTR Identifiler, Applied Biosystems) were studied in the city of Maracaibo, Venezuela and were compared with other published Latin-American populations for the same loci. Population and forensic parameters were estimated.     

Population genetic data for 18 STR loci in Costa Rica

Allele frequencies for 18 STR autosomal loci (D3S1358, VWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820, D16S539, TH01, TPOX, CSF1PO, Penta D, Penta E, D19S433, D2S1338 and SE33) were obtained from a sample of 191-500 unrelated individuals from Costa Rica, Central America.     

Explanatory factors of the relationship between gender diversity and corporate performance

In recent years a growing interest in gender diversity has arisen in the business context, and a significant number of research studies have analysed its effect on corporate performance. Nonetheless, these studies have not led to conclusive results, perhaps owing to the complexity of the relationship. The present work focuses on analysing two possible justifications of the contradictory effects of gender diversity on company performance: the business context and the optimum size of the female presence in decision-making bodies. The results obtained show that when working conditions and academic background are similar, women achieve better performance in sectors traditionally dominated by men. Moreover, to take the best advantage of gender diversity it is recommended that boards of directors should be balanced or have a slightly higher female presence.     

Politicization,banking experience and risk in savings banks

During the global financial crisis, criticism of the politicization and lack of professionalization of the savings banks has taken a central position in the political debate. The aim of this article is to analyze if the political presence of governing bodies in Spanish savings banks has been reflected in their various risk-taking behaviors before and during the financial crisis. We will also analyze whether the influence of the chairman’s banking experience matters. The results do not provide evidence that the composition of the boards of savings bank, or even their politicization, have played a role. However we show that savings banks run by a chairman with previous banking experience are likely to be significantly more solvent and less volatile.
