Analysis of ionic ratios in myocardial tissue and their relation to cardiac damage

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.     

Population genetics of nine short tandem repeat loci: allele frequency distribution in a Brazilian population sample

Gene and genotype frequencies in relation to the D3S1358, vWA, FGA, TH01, TPOX, CSF1PO, D5S818, D13S317, and D7S820 loci were determined in a sample of 290 unrelated individuals (204 Caucasians and 86 mulattoes) living in the city of S?o Paulo, Brazil. The sex test Amelogenin was also performed in all subjects from our sample, revealing the expected sex in all instances. Allele frequency data obtained from the analysis of these samples were in the usual range of other population groups with similar racial background. In the sample of Caucasian individuals, panmictic proportions were ruled out in relation to TPOX and CSF1PO loci, but only in the latter was the overall frequency of heterozygotes significantly less than expected. In the sample of mulattoes, Hardy-Weinberg proportions were rejected in relation to FGA and CSF1PO loci, but in no instance were the overall numbers of heterozygotes different from the corresponding expected ones under panmixia. Taking into account all this and also the number of tests performed, the degree of genetic heterogeneity of Brazilian populations, and the critical level reached by the significant results (1% < alpha<5%), the departures from panmixia here observed can be considered to be negligible in altering significantly biologic relationship odds calculated under the assumption of random matings.     

STR data for the AmpFlSTR Profiler Plus loci from Greece

Allele frequencies for the nine STRs included in the AmpFlSTR Profiler Plus kit (D3S1358, VWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317 and D7S820) were estimated from a sample of 143 unrelated individuals living in different regions of Greece.

Efficiency Measurement in Spanish Local Government: The Case of Municipal Water Services

In this work, we established a procedure for evaluation of the efficiency of the water supply. This procedure has allowed us to find that the proposed indicators have a discriminating capability in the analysis of the service, and to reject criticisms traditionally assigned to the sensitivity of the data envelopment analysis (DEA) technique in relation to degrees of freedom. The results obtained show that the population density, as a factor that defines one of the particular characteristics of the surroundings of each municipality, has a statistically significant impact on the indexes of efficiency, this affirmation not being extended to the public or private ownership of the service. The scale inefficiency is higher than the technical inefficiency. These typologies of efficiency are, principally, motivated by the supply side of the service, which is specially linked with the necessary infrastructure. The demand of the citizens is satisfied with a behavior close to optimal.     

Labor Reform and Dual Transitions in Brazil and the Southern Cone

The sequencing of transitions to democracy and to a market economy shaped the outcome of labor law reform and prospects for expanded labor rights in Argentina, Brazil, and Chile. Argentina and Brazil experienced democratic transitions before market economic reforms were consolidated in the 1990s. During the transition, unions obtained prolabor reforms and secured rights that were enshrined in labor law. In posttransition democratic governments, market reforms coincided with efforts to reverse earlier labor protections. Unable to block many harmful reforms, organized labor in Argentina and Brazil did conserve core interests linked to organizational survival and hence to future bargaining leverage. In Chile this sequence was reversed. Market economic policies and labor reform were consolidated under military dictatorship. During democratic transition, employers successfully resisted reforms that would expand labor rights. This produced a limited scope of organizational resources for Chilean unions and reduced prospects for future improvements.     

Striking hard rock veins. Multinational Corporations and Miners’ Unions in Mexico and the United States, 1906-1952

ABSTRACT

This paper analyzes simultaneous strikes during the first half of the 20th century in North America. The transformation of production in copper, lead, zinc, and silver mining districts determined the formation of a working class that operated between Mexico and the United States. Therefore, the labor conflicts combined market circumstances and management-imposed homologation of work structures across firm divisions with the international coordination of miners. The paper describes the emergence, growth, and demise of a regional industrial system.
