Acute Phase Responses of Different Positions of High-Goal (Elite) Polo Ponies

The aim of this study was to investigate the acute phase response (APR) in 15 horses by quantifying physiological venous blood variables and serum acute phase proteins (APP) at 5 minutes and 6 and 12 hours after a training match of high-goal polo. The horses were divided into three experimental groups based on their team positions, including defense (n = 6), midfield (n = 5), and attack (n = 4). Serum proteinograms were obtained by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Data were evaluated using analysis of variance for repeated measures. The match represented a high-intensity stimulus for all positions. Defenders appeared to use the anaerobic pathway more than the other positions, as shown by their lower pH and greater lactatemia. Alterations in muscle membrane permeability were observed in all horses, as seen by the increase in serum creatine kinase activity without a correlation with APR. Significant elevations in total serum protein, albumin, ceruloplasmin, haptoglobin, alpha-1 antitrypsin, and 23-kDa protein were seen only during the course of the physical exertion of the match, although there were no differences in these values among positions of the team. After 6 hours of the match, the concentration of transferrin declined, whereas that of alpha-1 acid glycoprotein remained unaltered at all assessed times. These results demonstrated that the defenders required the most use of the anaerobic pathway during the match, and that equestrian polo exercise triggers an acute phase response of relatively short duration; this APR is characterized as noninflammatory, as APR appears to be a physiological alteration related to the stress inherent in physical exercise. © 2013 Elsevier Inc.

The Grounding of Regional Integration for Brazil: Universalism, Sovereignty and Elite Perception

The aim of this article is to analyse the meaning of Mercosur for Brazilian foreign policy. To this end, we discuss the perceptions of the Brazilian elites concerning the regional integration process. The defence of the principle of inter-governmentalism is related to the conception of Mercosur's place within Brazil's international relations. The fact that principles such as universalism and sovereignty are very highly valued ends up affecting the deepening of the integration. The hypothesis of this article is that the Mercosur structure is in line with the perceptions of part of the Brazilian elites, which has put less emphasis on integration since the late 1990s. Our argument is that the current structure is insufficient to guarantee the dynamics of integration.
