1. Utilização do óleo essencial da Alpinia speciosa Schum, Zingiberaceae, no tratamento fisioterapêutico de pacientes com síndrome piramidal / Use essential oil of Alpinia speciosa Schum, Zingiberaceae in physical therapy of patients with pyramidal syndrome
A espasticidade muscular é um distúrbio motor decorrente das lesões em diferentes níveis do sistema nervoso central devido à lesões da medula espinhal, acidente vascular cerebral, paralisia cerebral ou esclerose múltipla, entre outros. O objetivo dessa pesquisa é investigar a utilização dos óleos essenciais da Alpinia speciosa Schum, Zingiberaceae

2. Morfologia e expressão dos fatores de regulação miogênica (MRFS) e IGF-1 no músculo esquelético de ratos submentidos ao treinamento resistido / Morphology and expression of myogenic regulatory factors (MRFs) and IGF-1 in rats skeletal muscle submitted to resistance training
O treinamento físico pode promover adaptações benéficas ao músculo esquelético. Entretanto, o treinamento de alta intensidade associado com um tempo insuficiente de recuperação, similar às condições de sobretreinamento, pode ocasionar efeitos prejudiciais. Os fatores reguladores miogênicos (MRFs) e o fator de crescimento IGF-1 são importantes re

3. Expressão dos fatores de regulação miogenica e de cadeia pesada da miosina no musculo estriado esquelitico da tilapia do Nilo (Oreochromis niloticus) durante o crecimento / Miogenic regulatory factors and myosin heavy chain expression in the striated skeletal muscle of the Nile tilapia (Oreochromis niloticus) during growth
Nos peixes, o conhecimento dos fatores que controlam o crescimento muscular e a análise das proteínas miofibrilares, é importante para entender a dinâmica do crescimento, a plasticidade e as adaptações musculares, principalmente, em espécies com grande valor comercial como a tilápia do Nilo (Oreochromis niloticus). No presente estudo, utilizou-se a t

4. AnÃlises histolÃgicas e proteÃmicas do miÃcito cardÃaco de ratos submetidos a diferentes intensidades de exercÃcio
Scientific literature have been described the regular which as an important factor in the health improvement. Among several causes have been related to this phenomenon, it was observed a crucial point that included the improvement of heart potency. This enhancement could be related to several factors such as cardiac muscle cells hypertrophy, which was consid

5. Expressão de fatores de regulação miogenica e metaloproteinases no musculo estriado esqueletico de ratos com insuficiencia cardiaca / Myogenic regulatory factors and metalloproteinase expression in rat skeletal muscle with heart failure
Background: Heart failure (HF) is associated with a skeletal muscle myopathy with increased expression of fast myosin heavy chains (MHC) and extracellular matrix (ECM) alterations. The skeletal muscle-specific molecular regulatory mechanisms controlling MHC expression during HF have not been described. Myogenic regulatory factors (MRF), a family of transcrip

6. Cotranslational assembly of myosin heavy chain in developing cultured skeletal muscle.
To examine how nascent myosin heavy chains associate with the cytoskeletons of developing muscle cells, we used pulse labeling, cell fractionation, and immunoprecipitation. More than 80% of nascent myosin heavy chains associate with the cytoskeleton. More than one-third of these nascent chains are not released by puromycin and/or RNase. The fraction of nasce

7. Myosin types during the development of embryonic chicken fast and slow muscles.
We have studied the myosin types present in developing fast and slow muscles of the chicken embryo. Myosin light chains were characterized by their mobility on sodium dodecyl sulfate/polyacrylamide gels; myosin heavy chains were identified by their reaction with antibodies specific for adult fast or adult slow myosin heavy chains. During development, the pec

8. Coevolution of head, neck, and tail domains of myosin heavy chains
Myosins, a large family of actin-based motors, have one or two heavy chains with one or more light chains associated with each heavy chain. The heavy chains have a (generally) N-terminal head domain with an ATPase and actin-binding site, followed by a neck domain to which the light chains bind, and a C-terminal tail domain through which the heavy chains

9. Regulation of myosin self-assembly: phosphorylation of Dictyostelium heavy chain inhibits formation of thick filaments.
Dictyostelium myosin is composed of two heavy chains and two pairs of light chains in a 1:1:1 stoichiometry. Myosin purified from amoebae grown in medium containing [32P]phosphate had two of the subunits labeled (0.2-0.3 mol of phosphate per mol of 210,000-dalton heavy chains and approximately 0.1 mol of phosphate per mol of 18,000-dalton light chain).

10. Comparison of adult, embryonic, and dystrophic myosin heavy chains from chicken muscle by sodium dodecyl sulfate/polyacrylamide gel electrophoresis and peptide mapping.
Chicken myosin heavy chains from adult fast white muscle fibers (both normal and dystrophic), adult slow red fibers, and embryonic presumptive fast white fibers were compared by sodium dodecyl sulfate/polyacrylamide gel electrophoresis and by peptide mapping. The heavy chain of slow red myosin migrated electrophoretically more slowly than the heavy chains of

11. Identification of the gene for fly non-muscle myosin heavy chain: Drosophila myosin heavy chains are encoded by a gene family.
In contrast to vertebrate species Drosophila has a single myosin heavy chain gene that apparently encodes all sarcomeric heavy chain polypeptides. Flies also contain a cytoplasmic myosin heavy chain polypeptide that by immunological and peptide mapping criteria is clearly different from the major thoracic muscle isoform. Here, we identify the gene that encod

12. Molecular cloning of mRNA sequences for cardiac alpha- and beta-form myosin heavy chains: expression in ventricles of normal, hypothyroid, and thyrotoxic rabbits.
We have isolated cDNA clones from thyrotoxic (pMHC alpha) and normal (pMHC beta) adult rabbit hearts. Restriction map analysis and DNA sequence analyses show that, although there is strong homology between overlapping regions of the two clones, they are distinctly different. The two clones exhibited 78-83% homology between the derived amino acid sequences an
