1. Importance of Genetic Testing in Dilated Cardiomyopathy: Applications and Challenges in Clinical Practice
Resumo A miocardiopatia dilatada (MCD) é uma síndrome caracterizada por dilatação ventricular esquerda e disfunção contrátil, sendo considerada a causa mais comum de insuficiência cardíaca em adultos jovens. O uso do sequenciamento de nova geração tem contribuído com a descoberta de uma grande quantidade de dados genômicos relacionados à MCD, i

2. Biochemical and Utralmicroscopic Evaluation of Myofibril Proteins and Collagen during Ageing in Broiler Chicken PSE (Pale, Sof, Exudative) Meat
Abstract The aim of this work was to study the myofibril proteins and collagen fraction changes in broiler chickens PSE (pale, soft, exudative) meat during ageing and their relationship to meat quality. The results presented an increase of myofibril proteins and collagen solubility promoted by the enhanced proteases activities during storage. Ultramicroscopi

3. Toughness in Santa Inês lamb meat has negative impact on consumer evaluation
RESUMO A maciez da carne é um atributo importante para os consumidores do mundo todo. Porém, ainda faltam estudos sobre sua importância na área de carne de cordeiro para consumidores brasileiros. O objetivo do estudo foi verificar a avaliação dos consumidores em relação à carne de cordeiro com força de cisalhamento elevada. Oito cordeiros foram aba

4. Carcass characteristics and fatty acid profile of Santa Inês lamb fed banana leftovers
ABSTRACT: The use of new feed resources, particularly local agroindustrial byproducts, such as banana, may be an option for replacing those traditionally used for sheep feed to reduce production costs. Thus, the aim of this study was to evaluate the dietary effects of replacing corn bran with banana leftovers on performance, carcass, non-carcass components,

5. Delayed carcass chilling improves tenderness of the beef gluteus medius muscle
Resumo: O objetivo deste trabalho foi avaliar os efeitos de uma taxa de resfriamento mais lenta sobre as características físico-químicas da alcatra (M. gluteus medius) de touros F1 Angus x Nelore, maturada por 14 dias. Carcaças leves e magras (n = 30) foram divididas em meias carcaças e selecionadas para controle (2°C por 24 horas) e tratamento (10°C

6. Anoxia stress and effect on flesh quality and gene expression of tilapia
Abstract We evaluated the effect of the length of stay out of water on stress, gene expression, pH variation, blood parameters, histological analysis and water holding capacity (WHC) in fillets of the Nile tilapia (Oreochromis niloticus) cultivated in net-tanks. For this purpose, the fishes were maintained out of water under different periods of anoxia. Thr

7. Morphological changes in rat rectus abdominis muscle induced by diabetes and pregnancy
The urethral muscle of diabetic pregnant rats is affected by long-term mild diabetes and short-term severe diabetes, which plays a crucial role in the pathogenesis of pelvic floor disorders. We hypothesized that muscles outside the pelvis are subject to similar changes. The current study aimed at analyzing the effects of long-term mild and short-term severe

8. Dietary glycerin does not affect meat quality of Ile de France lambs
ABSTRACT The objective of this study was to evaluate the physicochemical and nutritional characteristics of meat from three muscles of Ile de France lambs fed diets containing different levels of glycerin as an alternative to corn. Thirty non-castrated feedlot Ile de France lambs weighing 15±0.2 kg were housed in individual pens and slaughtered at 32±0.2 k

9. Muscle residual force enhancement: a brief review
Muscle residual force enhancement has been observed in different muscle preparations for more than half a century. Nonetheless, its mechanism remains unclear; to date, there are three generally accepted hypotheses: 1) sarcomere length non-uniformity, 2) engagement of passive elements, and 3) an increased number of cross-bridges. The first hypothesis uses sar

11. A influência do hormônio tireoideano nas proteínas estruturais da banda M no coração e no músculo esquelético de ratos. / The influence of thyroid hormone on M band structural proteins in the heart and skeletal muscle of rats.
Thyroid hormone (T3) regulates many functions of the heart and skeletal muscle. In this way, the present work identified the effect of T3 on the sarcomeric M band proteins, which are structural proteins from the heart and skeletal muscle. T3 down regulated M protein expression in the heart, one of the M band proteins, and, moreover, T3 could regulate M prote
