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.

Multi-choice mixed integer goal programming optimization for real problems in a sugar and ethanol milling company

Goal Programming (GP) is an important analytical approach devised to solve many realworld problems. The first GP model is known as Weighted Goal Programming (WGP). However, Multi-Choice Aspirations Level (MCAL) problems cannot be solved by current GP techniques. In this paper, we propose a Multi-Choice Mixed Integer Goal Programming model (MCMI-GP) for the aggregate production planning of a Brazilian sugar and ethanol milling company. The MC-MIGP model was based on traditional selection and process methods for the design of lots, representing the production system of sugar, alcohol, molasses and derivatives. The research covers decisions on the agricultural and cutting stages, sugarcane loading and transportation by suppliers and, especially, energy cogeneration decisions; that is, the choice of production process, including storage stages and distribution. The MCMIGP allows decision-makers to set multiple aspiration levels for their problems in which the more/higher, the better and the less/lower, the better in the aspiration levels are addressed. An application of the proposed model for real problems in a Brazilian sugar and ethanol mill was conducted; producing interesting results that are herein reported and commented upon. Also, it was made a comparison between MCMI GP and WGP models using these real cases. © 2013 Elsevier Inc.

Acquisition of suture skills during medical graduation by instructor-directed training: A randomized controlled study comparing senior medical students and faculty surgeons

Due to shortage of time and limited availability of faculty surgeons to teach basic surgical skills during medical graduation, the search for alternative ways of simulated training with feedback is needed. The purpose of this study was to compare the simulated teaching of suture skills to novice medical students by senior medical students and by experienced faculty surgeons. Forty-eight novice medical students were randomly assigned to three practice conditions on bench model (n = 16): self-directed suture training (control), senior medical student-directed suture skills' training, or experienced faculty surgeon-directed suture skills' training. Pre- and post-tests were applied. Global Rating Scale with blinded evaluation and self-perceived confidence based on Likert scale were used to assess all suture performances in pre- and post-training. Effect size was also calculated. The analysis made after training showed that the students who received feedback from the instructors had better performance based on the Global Rating Scale (all p < 0.0000) and felt more confident to carry out sutures (all p < 0.0000) when compared to the control. There was no significant difference (all p > 0.05) between the student-directed teaching and faculty-directed teaching groups. The magnitude of the effect (instructor-directed training suture) was considered large (>0.80) in all measurements. The acquisition of suture skills after student-directed training was similar to the training supervised by faculty surgeon, and the increase in suture performances of trainees that received instructor administered training was superior to self-directed learning. © 2013 Springer-Verlag Italia.

Prospects for commercial air-navigation in South America

The ALADI - ECLAC Seminar Latin American Association for Integration - Economic Commission for Latin America and the Caribbean Santiago, Chile, 15-17 April, 1997 Experts from the public and private sectors of Brazil, Chile, Colombia, Paraguay, Peru, Uruguay, and Venezuela participated on a private basis in an open debate. Representatives from the International Association of Latin American Air Transport (AITAL), the Latin American Civil Aviation Commission (CLAC), and the International Civil Aviation Organization (OACI) also attended the meeting.The topics analyzed in the Seminar were: 1. The situation and prospects for international air-transport: policies and tendencies in the United States and the European Union. 2. South American sub-regional agreements. 3. The evolution of national policies in the region. 4. Structural changes in corporate management. 5. The use of commercial air-traffic rights. 6. Security in air-navigation. 7. The challenges facing regional airlines.

ECLAC contributes with new workshops towards the goal of easing traffic congestion

A number of cities in Latin America played host to workshops on measures for reducing traffic congestion, as part of efforts to publicize the results of a project recently completed by ECLAC, and which received support from the German Agency for Technical Cooperation (GTZ). Congestion is beginning to pose a threat to the quality of life of the cities of the region; the most obvious manifestation of this congestion is the increase in daily travel time, especially in peak hours.The workshops are a contribution to efforts to curb congestion, since they help foster awareness of the extent of the negative consequences generated by the phenomenon, and are a means of publicizing options for dealing with it. This edition of the Bulletin outlines the contents of the workshops and their results. The workshops are offered to urban authorities and other institutions interested in training staff employed in positions involving traffic management.
