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. Effects of Mechanical Vibration in Neuromuscular Junctions and Fiber Type of the Soleus Muscle of Oophorectomized Wistar Rats
Resumo Objetivo Avaliar as junções neuromusculares (JNMs) e o tipo de fibras musculares do músculo sóleo de ratas Wistar ooforectomizadas e submetidas a um protocolo de vibração mecânica. Métodos Foram utilizadas 36 ratas randomizadas nos grupos pseudo-ooforectomia sem e com tratamento e ooforectomia sem e com tratamento. O tratamento foi realizado

3. Short-term creatine supplementation changes protein metabolism signaling in hindlimb suspension
The effect of a short-term creatine supplementation on hindlimb suspension (HS)-induced muscle atrophy was investigated. Creatine monohydrate (5 g/kg b.w. per day) or placebo, divided in 2 daily doses, was given by oral gavage for 5 days. Rats were maintained in HS with dietary supplementation concomitantly for 5 days. Body weight, soleus and EDL muscle mass

4. Concentration of collagen fibers in the musculature of broiler chickens fed with cupuacu seed by-product
RESUMO Neste estudo, foram quantificadas as concentrações de fibras colágenas de frangos expostos a crescentes concentrações de farinha de cupuaçu. A coleta de material foi realizada em cinco animais por tratamento, aos 70 dias de idade, nos grupos: controle, inclusão de 5% e de 10% de farinha de cupuaçu. Fragmentos dos músculos peitoral torácico (

5. 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

6. 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

7. Power amplifier circuits for functional electrical stimulation systems
Abstract Introduction: Functional electrical stimulation (FES) is a technique that has been successfully employed in rehabilitation treatment to mitigate problems after spinal cord injury (SCI). One of the most relevant modules in a typical FES system is the power or output amplifier stage, which is responsible for the application of voltage or current puls

8. The adductor pectoral fin muscle of Micropogonias furnieri (Perciformes: Sciaenidae): a morphological and histochemical study
ABSTRACT The adductor pectoral fin muscle in post-spawning females of the white croaker Micropogonias furnieri (Desmarest, 1823) is described from a morphological, histochemical and morphometric perspectives. A description of the morphological characteristics was conducted after dissections in different layers, down to the deep layer. Five muscles were found

9. 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

10. Implantation of muscle satellite cells overexpressing myogenin improves denervated muscle atrophy in rats
This study evaluated the effect of muscle satellite cells (MSCs) overexpressing myogenin (MyoG) on denervated muscle atrophy. Rat MSCs were isolated and transfected with the MyoG-EGFP plasmid vector GV143. MyoG-transfected MSCs (MTMs) were transplanted into rat gastrocnemius muscles at 1 week after surgical denervation. Controls included injections of untran

11. Three days of intermittent stretching after muscle disuse alters the proteins involved in force transmission in muscle fibers in weanling rats
The aim of this study was to determine the effects of intermittent passive manual stretching on various proteins involved in force transmission in skeletal muscle. Female Wistar weanling rats were randomly assigned to 5 groups: 2 control groups containing 21- and 30-day-old rats that received neither immobilization nor stretching, and 3 test groups that rece

12. NERVE ENDINGS AND VASCULAR SUPPLY IN SEMITENDINOSUS TENDON OF CEREBRAL PALSY CHILDREN
Objective:To evaluate the distribution of SP (substance P) and S-100 peptide immunoreactivity, as well as the vascular supply of tissues commonly used as grafts for anterior cruciate ligament (ACL) reconstruction. A second aim was to compare the above mentioned distribution in the semitendinosus muscle tendons of cerebral palsy (CP) patients with the semiten
