Cell degeneration and performance decline of immobilized Clostridium acetobutylicum on bagasse during hydrogen and butanol production by repeated cycle fermentation

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.

Los micronutrientes son componentes minoritarios pero esenciales de nuestra dieta. Actualmente existe una creencia en los países occidentales desarrollada y apoyada por evidencias científicas que supone que el consumo de ciertos micronutrientes previene importantes problemas de salud. Se alude a un fenómeno conocido como estrés oxidativo, que es causa de envejecimiento y degeneración celular y que puede ser contrarrestado mediante el consumo regular de micronutrientes antioxidantes. En concreto, entre el amplio colectivo de personas que practican deporte, esta creencia está muy extendida y arraigada y las ventas de determinados productos se han disparado en las dos últimas décadas, suponiendo un gran mercado de consumo para las empresas del sector; de hecho es frecuente encontrar en la mayoría de los centros deportivos y gimnasios de nuestras ciudades algún estante en el que se exhiben para su venta complementos nutricionales que contienen productos antioxidantes que prometen mejorar la salud y el rendimiento… El presente trabajo pretende responder a la cuestión acerca de la necesidad o conveniencia de emplear suplementos nutricionales antioxidantes para mejorar la salud de las personas que practican deporte de forma regular.Abstract: Micronutrients are minority but essential components of our diet. Nowadays a belief exists in the western countries developed and supported by scientific evidences that it supposes that the consumption of certain micronutrients prevents serious health problems. One alludes to a phenomenon known as oxidative stress, that is a reason of aging and cell degeneration and that can be offset by means of the regular consumption antioxidant micronutrients. In fact, among the wide group of persons who practise sport, this belief is very widespread and deep-rooted and the sales of certain products have gone off in last two decades, supposing a great consumer market for the companies of the sector; of fact it’s frequent to find in the majority of the sports centers of our cities some shelf in which there show themselves to sale nutritional complements that contain antioxidant products that promise to improve the health and performance … the present work tries to answer to the question brings over of the need or convenience of using nutritional antioxidant supplements to improve the health of the persons who practise sport.
