Myocardial function during chronic food restriction in isolated hypertrophied cardiac muscle
(Lippincott Williams & Wilkins, 2000-10-01)
Background: the effect of food restriction (FR) on myocardial performance has been studied in normal hearts. Few experiments analyzed the effects of undernutrition on hearts subjected to cardiac overload. The aim of this ...
Direct effects of colchicine on myocardial function - Studies in hypertrophied and failing spontaneously hypertensive rats
(Lippincott Williams & Wilkins, 1999-01-01)
The aging spontaneously hypertensive rat (SHR) is a model in which the transition from chronic stable left ventricular hypertrophy to overt heart failure can be observed. Although the mechanisms for impaired function in ...
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 ...
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 ...
Comparative mechanical study of isolated papillary muscle from Wistar-Kyoto and Wistar rats
(1994-01-01)
Isolated papillary muscles have often been used in myocardial mechanical function studies. The objective of the present study was to compare the mechanical function of papillary muscle isolated from left ventricle between ...
Efeito do Nível de Energia da Dieta e da Exposição Prévia ao Calor sobre a Respiração Mitocondrial do Músculo Cardíaco de Frangos de Corte
(1999-01-01)
This work was conducted aiming to evaluate the effect of dietary energy level and the previous heat exposure on the respiratory activity of the mitochondria from the cardiac muscle of broiler chickens. It was used broiler ...
The influence of temporal food restriction on the performance of isolated cardiac muscle
(Elsevier B.V., 2001-04-01)
In this study we assessed the mechanical function of isolated left ventricular papillary muscles from 60 day-old male Wistar-Kyoto rats (WKY) subjected to different periods of food restriction (FR). The food-restricted ...
Influência da pós-carga sobre a taxa de variação da tensão desenvolvida (dT/dt). Estudo em músculo cardíaco isolado.
(1995-11-01)
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 ...
Effects of protein-calorie restriction on mechanical function of hypertrophied cardiac muscle
(Sociedade Brasileira de Cardiologia (SBC), 1999-04-01)
OBJECTIVE: To assess the effect of food restriction (FR) on hypertrophied cardiac muscle in spontaneously hypertensive rats (SHR). METHODS: Isolated papillary muscle preparations of the left ventricle (LV) of 60-day-old ...
Excessive moderator band in a female cat’s left ventricle
