Myosin heavy chain expression and atrophy in rat skeletal muscle during transition from cardiac hypertrophy to heart failure
(Blackwell Publishing, 2003-08-01)
The purpose of this investigation was to determine whether changes in myosin heavy chain (MHC) expression and atrophy in rat skeletal muscle are observed during transition from cardiac hypertrophy to chronic heart failure ...
Myostatin and follistatin expression in skeletal muscles of rats with chronic heart failure
(Wiley-Blackwell Publishing, Inc, 2010-02-01)
P>Skeletal muscle abnormalities can contribute to decreased exercise capacity in heart failure. Although muscle atrophy is a common alteration in heart failure, the mechanisms responsible for muscle mass reduction are not ...
Influência da pós-carga sobre a taxa de variação da tensão desenvolvida (dT/dt). Estudo em músculo cardíaco isolado.
PURPOSE: To evaluate the effects of afterload on peak rate of tension rise (dT/dt) in the isolated muscle. METHODS: Left ventricular papillary muscles from Wistar rats were studied in isometric and isotonic afterloaded ...
Modificacoes na ação mecânica do coração isolado de cobaia por doses de propafenon capazes de alterar o eletrocardiograma
Inotropic effects of Propafenon were studied in isovolumic isolated guinea pig hearts submitted to infusion of the drug during 10 minutes. The dosages utilized caused: bradycardia, depression of AV nodal conduction and QRS ...
Heart failure alters matrix metalloproteinase gene expression and activity in rat skeletal muscle
(Blackwell Publishing, 2006-12-01)
Heart failure is associated with a skeletal muscle myopathy with cellular and extracellular alterations. The hypothesis of this investigation is that extracellular changes may be associated with enhanced mRNA expression ...
