2. Effects of Low-level Laser Therapy on Muscle Repair in Rats with Chronic Alcohol Intake
ABSTRACT This study aimed to investigate the effects of low-level laser therapy (LLLT) on muscle repair in rats with chronic alcohol intake. Thirty male Wistar rats were distributed into three groups: injured tibialis anterior (TA) muscle without treatment (IC); chronic ingestion of alcohol plus injured TA muscle (AI); and chronic ingestion of alcohol plus i

3. 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

4. The effects of low level laser therapy on injured skeletal muscle
The main purpose of the present study was to investigate the effects of low-level laser therapy (LLLT) used in two different fluencies on injured skeletal muscle after cryolesion by means of histopathological analysis and immunohistochemistry for COX-2. A total of sixty male Wistar rats were randomly distributed into three groups: injured animals without any

5. Efeito do ultrassom terapêutico na regeneração muscular e na expressão de fatores miogênicos em músculo esquelético de rato após lesão. / Effect of therapeutic ultrasound in muscle regeneration and the expression of myogenic factors in skeletal muscle of rats after injury.
O ultrassom (US) tem sido utilizado para o tratamento clínico de uma série de condições inflamatórias músculo esqueléticas porém, sua eficácia ainda não está comprovada. O objetivo deste estudo foi avaliar o efeito do US terapêutico na regeneração do músculo esquelético de rato após criolesão bem como, seu papel na expressão de RNAm de fat

6. Avaliação estrutural, estereológica e biomecânica do efeito da aplicação do ultrassom no reparo da lesão lacerativa experimental do gastrocnêmio de rato / Biomechanical, stereological and structural assessment of the ultrasound effect on the repair of muscle injury in rats
O objetivo deste estudo foi avaliar os efeitos do ultrassom pulsado (USp) no reparo muscular em um modelo experimental de lesão lacerativa do músculo gastrocnêmio medial em ratos Wistar. Vinte ratos foram tratados diariamente com USp (50%), 1MHz, 0,57W/cm² de intensidade por 5 min. formando os grupos tratados (GT), e 20 animais constituíram os grupos co

7. Efeitos do treinamento resistido associado com decanoato de nandrolona sobre a expressão gênica de moduladores de vias de hipertrofia e atrofia do músculo esquelético
Androgenic-anabolic steroids (AAS) are spread among athletes and no athletes in order to improve performance or physical appearance. AAS targets the satellite cells in skeletal muscles, which are the major precursors of the skeletal muscle, and are essential for muscle growth and repair. When activated, in the presence of several factors, including myogenic

8. Efeito da fototerapia com laser de baixa potência no remodelamento dos colágenos i e iii no processo de regeneração do músculo esquelético de rato. / Effect of the fototerapia with laser of low power in the remodelamento of colágenos i and III in the process of regeneration of the esquelético muscle of rat.
A fototerapia com laser de baixa potência (LBP) tem sido utilizada para estimular a reparação tecidual em diferentes tecidos. Entretanto, seu papel no remodelamento muscular, especialmente sua ação no componente colagênico da matriz extracelular, ainda não está bem esclarecido. O objetivo do presente estudo foi investigar o efeito do laser no remodel

9. Efeito do uso de tela reabsorvível (Interceed) sobre a musculatura estriada esquelética após cirurgia de reparo de tendão : estudo experimental em ratos wistar
Interceed is an absorbable sheet made of oxidized cellulose often used to prevent adhesions mainly in gynecology surgeries. OBJECTIVES: to evaluate if there is adhesion reduction after tendon repair when using absorbable sheet (Interceed) as a physical barrier of protection. MATERIAL AND METHOD: 20 Wistar rats divided in 3 groups were used. The first group,

10. Genetic Manipulation of Dysferlin Expression in Skeletal Muscle : Novel Insights into Muscular Dystrophy
Mutations in the gene DYSF, which codes for the protein dysferlin, underlie Miyoshi myopathy and limb-girdle muscular dystrophy 2B in humans and produce a slowly progressing skeletal muscle degenerative disease in mice. Dysferlin is a Ca2+-sensing, regulatory protein that is involved in membrane repair after injury. To assess the function of dysferlin in hea

11. Muscle differentiation during repair of myocardial necrosis in rats via gene transfer with MyoD.
Myocardial infarcts heal by scar formation because there are no stem cells in myocardium, and because adult myocytes cannot divide and repopulate the wound. We sought to redirect the heart to form skeletal muscle instead of scar by transferring the myogenic determination gene, MyoD, into cardiac granulation (wound repair) tissue. A replication-defective aden

12. Skeletal muscle stem cells
Satellite cells are myogenic stem cells responsible for the post-natal growth, repair and maintenance of skeletal muscle. This review focuses on the basic biology of the satellite cell with emphasis on its role in muscle repair and parallels between embryonic myogenesis and muscle regeneration. Recent advances have altered the long-standing view of the satel
