The Role of Exercise in Preventing and Treating Depression.

Abstract: Depression is a leading cause of global burden. The mainstay of treatment is pharmacological and psychological interventions. While effective, not all people will respond to those treatments and alternative approaches for preventing and treating depression are required. Recent literature has demonstrated that higher physical activity (PA) levels and exercise confer protective effects on incident depression. Also, exercise has demonstrated efficacy on reducing symptoms for people with depression. Despite its effectiveness, similar to other treatments, some people may benefit more from exercise and identifying these potential predictors of response is necessary to deal with patients' and professionals' expectations. Dropout from exercise interventions is comparable to dropout from other treatments for depression and similar to dropout from exercise in other clinical populations. However, some strategies to increase adherence are important. In the present article, we provide an updated overview of the use of PA and exercise for the prevention and treatment of depression.

Características da Carcaça de Novilhos Red Angus Superprecoces Abatidos com Diferentes Pesos

Abstract: The carcass quantitative characteristics of feedlot finished Red Angus steers, with initial age of eight months and 189 kg, slaughtered with 340, 370, 400 or 430 kg (SW), were evaluated. The number of days to reach the respective weight was 114, 144, 173 and 213 days. The diet contained 13.13% crude protein, 2.7 Mcal digestible energy/kg DM and a roughage:concentrate ratio of 56:44. Carcass dressing percentage and conformation were not affected by the slaughter weight. The saw cut weight although increasing linearly in weight (91.73; 103.26; 106.20 and 116.66 kg) as the slaughter weight increased, declined linearly when expressed in relation to cold carcass weight. Side cut percentage showed the highest increase (23.36; 25.40; 28.50 and 35%) as the slaughter weight increased, following the increase of subcutaneous fat thickness (3.91; 6.16; 6.16 and 9.58 mm). The Longissimus dorsi muscle (LMA) increased linearly as the slaughter weight increased (LMA = 27.48 + 0.083SW) while the LMA/100 kg of cold carcass weight declined linearly (LMA/100 kg carc. = 45.14 - 0.0425SW). According to the regression equation the minimum subcutaneous fat thickness required by the slaughter weights (3 mm) would be reached at 327 kg of live weight. Considering the minimum carcass weight of 180 kg, it would be reached with the slaughter weight of 337 kg. Using Red Angus breed to produce steers to be slaughtered at young age the slaughter weight should not surpass 400 kg, in order to not exceed the 6 mm of subcutaneous fat thickness, to avoid the carcass trimming for fat excess.
