1. Effects of physical exercise on skeletal muscles of rats with cerebral ischemia
Physical exercise is a known preventive and therapeutic alternative for several cerebrovascular diseases. Therefore, the objective of the present study was to evaluate the motor performance and histomorphometry of the biceps brachii, soleus, and tibialis anterior muscles of rats submitted to a treadmill training program prior to the induction of cerebral isc

2. A comprehensive transcriptome analysis of skeletal muscles in two Polish pig breeds differing in fat and meat quality traits
Abstract Pork is the most popular meat in the world. Unfortunately, the selection pressure focused on high meat content led to a reduction in pork quality. The present study used RNA-seq technology to identify metabolic process genes related to pork quality traits and fat deposition. Differentially expressed genes (DEGs) were identified between pigs of Pulaw

3. Myostatin promotes distinct responses on protein metabolism of skeletal and cardiac muscle fibers of rodents
Myostatin is a novel negative regulator of skeletal muscle mass. Myostatin expression is also found in heart in a much less extent, but it can be upregulated in pathological conditions, such as heart failure. Myostatin may be involved in inhibiting protein synthesis and/or increasing protein degradation in skeletal and cardiac muscles. Herein, we used cell c

4. Effect of low-level laser therapy (808 nm) on skeletal muscle after endurance exercise training in rats
BACKGROUND: Low-level laser therapy (LLLT) has been demonstrated to be effective in optimizing skeletal muscle performance in animal experiments and in clinical trials. However, little is known about the effects of LLLT on muscle recovery after endurance training. OBJECTIVE: This study evaluates the effects of low-level laser therapy (LLLT) applied after

5. Morphological aspects and Cox-2 expression after exposure to 780-nm laser therapy in injured skeletal muscle: an in vivo study
Background: The effectiveness of low-level laser therapy in muscle regeneration is still not well known. Objective: To investigate the effects of laser irradiation during muscle healing. Method: For this purpose, 63 rats were distributed to 3 groups: non-irradiated control group (CG); group irradiated at 10 J/cm² (G10); and group irradiated at 50 J/cm² (G

6. Exercise training prevents skeletal muscle damage in an experimental sepsis model
OBJECTIVE: Oxidative stress plays an important role in skeletal muscle damage in sepsis. Aerobic exercise can decrease oxidative stress and enhance antioxidant defenses. Therefore, it was hypothesized that aerobic exercise training before a sepsis stimulus could attenuate skeletal muscle damage by modulating oxidative stress. Thus, the aim of this study was

7. Protein turnover, amino acid requirements and recommendations for athletes and active populations
Skeletal muscle is the major deposit of protein molecules. As for any cell or tissue, total muscle protein reflects a dynamic turnover between net protein synthesis and degradation. Noninvasive and invasive techniques have been applied to determine amino acid catabolism and muscle protein building at rest, during exercise and during the recovery period after

8. Skeletal muscle major histocompatibility complex class I and II expression differences in adult and juvenile dermatomyositis
OBJECTIVE: To analyze major histocompatibility complex expression in the muscle fibers of juvenile and adult dermatomyositis. METHOD: In total, 28 untreated adult dermatomyositis patients, 28 juvenile dermatomyositis patients (Bohan and Peter's criteria) and a control group consisting of four dystrophic and five Pompe's disease patients were analyzed.

9. Avaliação da musculatura estriada de membros inferiores na limitação funcional ao exercício em pacientes com hipertensão arterial pulmonar / Assessment of skeletal muscle of lower limb in functional exercise limitation in patients with pulmonary arterial hypertension
Introdução: A hipertensão arterial pulmonar (HAP) é uma doença progressiva extremamente grave, que evolui com insuficiência cardíaca direita e morte. Apesar do avanço do tratamento farmacológico, o prognóstico permanece reservado com taxa de sobrevida de 86%, 70% e 55% em 1, 3 e 5 anos, respectivamente. A dispnéia progressiva e a intolerância ao

10. Análise proteômica das respostas agudas e crônicas ao exercício de endurance no músculo esquelético de ratos / Proteomic investigation of the acute and chronic changes in rat skeletal muscle in reseponse to endurence exercise
In the present work the acute and chronic changes in rat skeletal muscle in response to endurance exercise were investigated by proteomic analysis. The results are presented in two separated studies. In the first study gastrocnemius muscle were sampled from control non exercised animals and from animals exercised to exhaustion in an incremental manner in a t

11. Characterization of angiotensin-converting enzymes 1 and 2 in the soleus and plantaris muscles of rats
Angiotensin-converting enzymes 1 (ACE1) and 2 (ACE2) are key enzymes of the renin-angiotensin system, which act antagonistically to regulate the levels of angiotensin II (Ang II) and Ang-(1-7). Considerable data show that ACE1 acts on normal skeletal muscle functions and architecture. However, little is known about ACE1 levels in muscles with different fiber

12. Proteínas marcadoras do exercício físico aeróbio em tecido muscular de ratos treinados em diferentes intensidades. / Marker proteins of aerobic exercises in muscle tissue of rats trained at different intensities.
Years ago physical exercise has been used both as a tool in promoting health and in search for a better performance. Muscle tissue, which is directly involved with exercise, is a dynamic tissue, with high adaptive capacity, whose cells pass through a constant remodeling in response to different functional demands. This adaptive process is related to transcri
