Influência da posição e tempo de irradiação sobre a capacidade de desinfecção em forno de micro-ondas

Objective: To evaluate the variations of temperature in 2 models of domestic micro-wave ovens, single emission (F 1) and dual emission of waves (F 2), to investigate areas of higher and lower intensity of the electromagnetic field. Materials and methods: A beaker containing water (60mL, 26°C) was irradiated into each of 5 positions (front - P 1; right - P 2; posterior - P 3; left - P 4; central - P 5) within each oven (900W/ 2min). To evaluate the effectiveness of disinfection in F 2, Bacillus subtilis suspension was irradiated in each of the 5 positions for 2, 4 and 6minutes. Data were analyzed by Kruskal-Wallis and nonparametric multiple comparisons at 5% significance level. Results: 84.80°C (F 1) and 92.01°C (F 2) were mean levels of temperature. For F 1, the positions P 1, P 2, P 3 and P 5 showed similar values among them and upper than P 4, while for F 2, the positions P 1, P 2 and P 4 were similar among them and upper than P 3 and P 5. Kruskal-Wallis test found significant differences between positions and models of ovens (p<0.05). It was observed that P 2 promoted bacterial death from 4min of irradiation, while the other positions promoted disinfection at 6min of irradiation. Conclusion: The protocols of position and time specified for the various procedures in microwave ovens can be different according to the characteristics of each device due to the electromagnetic field heterogeneity. © 2011 Sociedade Portuguesa de Estomatologia e Medicina Dentária.

Relação entre o desempenho e período de recuperação após enfermidades ósseas do membro torácico distal de cavalos puro sangue inglês

It is well established in the literature that musculoskeletal injuries are important compromising agents in the performance of Thoroughbred horses. In Brazil, there are no studies on the interrelation between lay-up period post-injury and retirement of racehorses due to musculoskeletal injures. The aim of this study is to determine the relationship between rehabilitation times of track injures and variables of prior race performance and later return to competitions. The radiographic reports and athletic history of 416 thoroughbreds during the period between 2003 and 2006 were examined; they were selected based on continued presentations after injury diagnosis. The temporal variables (post-injury rehabilitation time) and performance variables (race score before and after injury) were evaluated by multivariate correspondence analysis of the data and represented in perceptual maps. Correspondence was observed between most of the animals that had a short lay-up post-injury and variables that denote decline in subsequent performance. Considering the integrity of the bone healing process as crucial for the horse to be able to handle later training routines and competitions, shortening this period could lead to an imbalance of the bone repair metabolism, thus resulting in performance decline and compromise of the horse athletic career.

Concentrações de ferro, cobre, zinco e manganês em equinos da raça Puro-sangue Lusitano, antes e após exercício1

In order to evaluate the sera concentrations of iron, copper, zinc and manganese trace minerals in thirty Pure-bred Lusitano athlete horses before and after exercise certified by clinical and laboratory assessments were studied. Blood samples were taken before and after 20 minutes of a dairy trot and gallop slight training, perfomed in a sandy floor ring, to measure the mineral concentrations, by atomic absorption spectrophotometry. It was observed that after exercising, the serum activity of iron did not change (P=0.2365), whereas copper values have significantly risen after training (P<0.001). On the other hand, zinc and manganese trace minerals decreased after exercise (P<0.001). In conclusion, it is possible to consider that the short time exercise may trigger sweating and consequently to change the seru.
