1. The promise of growth hormone in sport: doped or duped
ABSTRACT Skeletal muscle is a target tissue of GH. Based on its anabolic properties, it is widely accepted that GH enhances muscle performance in sports. Athletic performance depends on muscle strength and the energy required to power muscle function. The energy required to power muscle function is derived from a continuum of anaerobic and aerobic sources. M

2. THE SINGLE NUCLEOTIDE POLYMORPHISMS OF MYOSTATIN GENE AND THEIR ASSOCIATIONS WITH GROWTH AND CARCASS TRAITS IN DAHENG BROILER
ABSTRACT Myostatin (MSTN) is a negative regulator of skeletal muscle growth. In order to investigate whether there is a correlation between MSTN polymorphisms and chicken production performance, in this study, single nucleotide polymorphisms (SNPs) in MSTN gene were examined across 180 Daheng broilers by direct sequencing of PCR product, and the correlations

3. Isolated branched-chain amino acid intake and muscle protein synthesis in humans: a biochemical review
RESUMO No treinamento físico, buscam-se, além de uma dieta adequada, recursos ergogênicos que possam maximizar direta e/ou indiretamente o desempenho físico. Entre as categorias de recursos ergogênicos, o nutricional compreende a modulação da composição dietética e/ou uso de suplementação. A comercialização dos suplementos de aminoácidos de ca

4. Expression of Myostatin (Mstn) and Myogenin (Myog) Genes in Zi And Rhine Goose and Their Correlation with Carcass Traits
ABSTRACT The aim of this study was to investigate the effects of Myostatin (MSTN) and MyoGenin (MyoG) on goose skeletal muscle growth. In this study, MSTN and MyoG gene expression in breast and leg muscle of Zi and Rhine goose were detected by Real-time Polymerase Chain Reaction (PCR), and the correlations between genes expression levels and carcass traits w

5. 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

6. Sexual transmission of American trypanosomiasis in humans: a new potential pandemic route for Chagas parasites
BACKGROUND The Trypanosoma cruzi infection endemic in Latin America has now spread to several countries across four continents; this endemic involves triatomine vector-free protists. We hypothesised that the sexual transmission of T. cruzi contributes to the ongoing spread of Chagas disease. OBJECTIVES A short-term longitudinal study was conducted to eva

7. Erythropoietin reduces the expression of myostatin in mdx dystrophic mice
Erythropoietin (EPO) has been well characterized as a renal glycoprotein hormone regulating red blood cell production by inhibiting apoptosis of erythrocyte progenitors in hematopoietic tissues. EPO exerts regulatory effects in cardiac and skeletal muscles. Duchenne muscular dystrophy is a lethal degenerative disorder of skeletal and cardiac muscle. In this

8. Putative role of ischemic postconditioning in a rat model of limb ischemia and reperfusion: involvement of hypoxia-inducible factor-1α expression
Hypoxia-inducible factor-1α (HIF-1α) is one of the most potent angiogenic growth factors. It improves angiogenesis and tissue perfusion in ischemic skeletal muscle. In the present study, we tested the hypothesis that ischemic postconditioning is effective for salvaging ischemic skeletal muscle resulting from limb ischemia-reperfusion injury, and that the m

9. Atividade física e suplementação nutricional de leucina associadas ao crescimento tumoral : estudo do perfil hormonal de ratos implantados com carcinossarcomia de Walker 256 / Physical activity and nutritional supplementation with leucine associated with tumor growth : study of hormonal profile in Walker 256
The cancer-cachexia is characterized by the development of anorexia, asthenia, weight loss, early satiety, anaemia and especially changes in the metabolism of carbohydrate, fat and protein in these cancer patients. The amino acid leucine acts promoting cell signalling by inhibiting the protein catabolism and stimulating the protein synthesis in skeletal musc

10. Differentially expressed genes and miRNA identification in pig skeletal muscle / Identificação de genes diferencialmente expressos e miRNAs em músculo esquelético de suínos
The pig (Sus scrofa) is considered an important animal for meat production. This interest revolves around the potential for muscle growth, which usually is associated with certain characteristics during prenatal myogenesis. To study the genes responsible for these characteristics, expressed sequence tags (EST) provide direct information about the transcripto

11. Expressão gênica e protéica de fatores reguladores miogênicos e da miostatina no músculo esquelético do pirarucu (Arapaima gigas) durante o crescimento / Gene and protein expression of myogenic regulatory factors and myostatin in skeletal muscle of pirarucu (Arapaima gigas) during growth
O pirarucu (Arapaima gigas) caracteriza-se como uma espécie promissora para a Aqüicultura, devido principalmente às suas características de rápido crescimento e rusticidade. Sua criação em regime intensivo tem obtido enorme sucesso, podendo alcançar até 10 quilos de peso corporal em apenas um ano de criação. O pirarucu é considerado hoje uma das

12. Expressão gênica de fatores que controlam o crescimento muscular do pacu (Piaractus mesopotamicus) / Gene expression of factors that control the pacu (Piaractus mesopotamicus) skeletal muscle growth
Nos peixes, o crescimento muscular ocorre por hipertrofia e hiperplasia a partir da proliferação e diferenciação das células satélites, processos regulados pela expressão de fatores de transcrição e de crescimento. Os objetivos desse trabalho foram: (1) avaliar a morfologia, morfometria e expressão gênica da MyoD, miogenina e IGF-I na musculatura
