1. EFFECTS OF AEROBIC EXERCISE TRAINING ON OXIDATIVE STRESS IN THE SKELETAL MUSCLES OF OBESE RATS
RESUMO Introdução Obesidade é uma desordem metabólica complexa e multifatorial, caracterizada pelo acúmulo de gordura corporal. O exercício físico tem a capacidade de aumentar o gasto energético e promover efeito reparador por meio da modulação das defesas antioxidantes endógenas. Objetivo Avaliar os efeitos da dieta hiperlipídica (DHL) sobre

2. The acute effects of strength, endurance and concurrent exercises on the Akt/mTOR/p70S6K1 and AMPK signaling pathway responses in rat skeletal muscle
The activation of competing intracellular pathways has been proposed to explain the reduced training adaptations after concurrent strength and endurance exercises (CE). The present study investigated the acute effects of CE, strength exercises (SE), and endurance exercises (EE) on phosphorylated/total ratios of selected AMPK and Akt/mTOR/p70S6K1 pathway prot

3. 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

4. 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

5. Expressão do Coativador-1 do Peroxisome Proliferator-Activated Receptor- (PGC-1) em fígado e músculos esqueléticos soleus e plantaris de ratos machos Wistar submetidos ao exercício físico voluntário crônico / Peroxisome Proliferator-Activated Receptor- - Coactivator-1 ( PGC-1 ) expression in the liver and skeletal muscles soleus and plantaris of male Wistar rats subjected to chronic voluntary exercise
INTRODUCTION: The Peroxisome Proliferator-Activated Receptor- - Coactivator 1 ( PGC-1 e ) is a protein responsible for the connection between environmental stimuli and cell metabolic response. Its presence is important in fat tissue, hepatic and skeletal muscle and in animals on brown fat tissue. Interact with nuclear receptors modulating the mitochondrial b

6. Cyclosporin-A does not affect skeletal muscle mass during disuse and recovery
Cyclosporin-A (CsA) is an immunosuppressive drug that acts as an inhibitor of calcineurin, a calcium phosphatase that has been suggested to play a role in skeletal muscle hypertrophy. The aim of the present study was to determine the effect of CsA administration (25 mg kg-1 day-1) on skeletal muscle mass and phenotype during disuse and recovery. Male Wistar

7. Ginseng administration protects skeletal muscle from oxidative stress induced by acute exercise in rats
Enzymatic activity was analyzed in the soleus, gastrocnemius (red and white) and plantaris muscles of acutely exercised rats after long-term administration of Panax ginseng extract in order to evaluate the protective role of ginseng against skeletal muscle oxidation. Ginseng extract (3, 10, 100, or 500 mg/kg) was administered orally for three months to male

8. Effects of impulse blockade on the contractile properties of rat skeletal muscle.
1. Pressure was used to produce a localized block of impulse conduction in motor nerve fibres supplying rat plantaris and soleus muscles. After 1 week of inactivity both muscles exhibited marked atrophy of type I and type II muscle fibres. 2. In treated plantaris and soleus muscles the specific tetanic tensions were reduced to approximately half those of unt

9. Angiomotin p80/p130 ratio: a new indicator of exercise-induced angiogenic activity in skeletal muscles from obese and non-obese rats?
Skeletal muscle capillarisation responds to physiological and pathological conditions with a remarkable plasticity. Angiomotin was recently identified as a new pro-angiogenic molecule. Angiomotin is expressed as two protein isoforms, p80 and p130. Whereas p80 stimulates endothelial cell migration and angiogenesis, p130 is rather characteristic of stabilized

10. Differences between contractions in vitro of slow and fast rat skeletal muscle persist after random reinnervation.
1. The medial popliteal nerve was sectioned in adult rats, and reinnervation was permitted after nerve reunion. Reinnervation was observed in soleus (slow twitch) and plantaris (fast twitch) muscles for periods of 4-21 months after the initial operation. 2. In the reinnervated muscles, isometric twitch time to peak (contraction time) and time to half-relaxat

11. Comparison of morphological and biochemical parameters of growth in rat skeletal muscles.
Morphological and biochemical parameters of cellular growth of four skeletal muscles were examined in male Sprague-Dawley rats from 25 to 165 days of age. The number of muscle fibres decreased in the soleus (41%), plantaris (20%), extensor digitorum longus (25%), and biceps brachii (19%) from 25 to 165 days of age, while nuclear number increased in each musc

12. Transcription Enhancer Factor 1 Binds Multiple Muscle MEF2 and A/T-Rich Elements during Fast-to-Slow Skeletal Muscle Fiber Type Transitions
In adult mouse skeletal muscle, β-myosin heavy chain (βMyHC) gene expression is primarily restricted to slow type I fibers; however, its expression can be induced in fast type II fibers in response to a sustained increase in load-bearing work (mechanical overload [MOV]). Our previous βMyHC transgenic and protein-DNA interaction studies have identified an
