Differential influences of high fat diet on cardiac remodeling from normotensive and spontaneously hypertensive rats
(Circulation, 2008-09-16) [Resumo]
Myocardial dysfunction induced by food restriction is related to morphological damage in normotensive middle-aged rats
(Journal of Biomedical Science, 2005-07-01) [Artigo]
Previous works from our laboratory have revealed that food restriction (FR) promotes discrete myocardial dysfunction in young rats. We examined the effects of FR on cardiac function, in vivo and in vitro, and ultrastructural ...
Influências de dietas ricas em ácidos graxos saturados e insaturados sobre o miocárdio de ratos
(Arquivos Brasileiros de Cardiologia, 2007-03-01) [Artigo]
OBJETIVOS: O estudo avaliou a influência de dietas ricas em ácidos graxos saturados (AGS) e ácidos graxos insaturados (AGI) sobre a função mecânica, a morfologia e o estresse oxidativo do miocárdio de ratos. MÉTODOS: Ratos ...
Follow-up study of morphology and cardiac function in rats undergoing induction of supravalvular aortic stenosis
(Arquivos Brasileiros de Cardiologia, 2003-12-01) [Artigo]
OBJETIVO: Caracterizar, evolutivamente, o modelo experimental de hipertrofia ventricular esquerda (HVE) por indução de estenose aórtica supravalvar em ratos jovens. MÉTODOS: Ratos Wistar foram submetidos a toracotomia para ...
Growth hormone and heart failure: Oxidative stress and energetic metabolism in rats
(Growth Hormone & Igf Research, 2008-08-01) [Artigo]
Several evidences point for beneficial effects of growth hormone (GH) in heart failure (HF). Taking into account that HF is related with changes in myocardial oxidative stress and in energy generation from metabolic pathways, ...
Detection of Altered Risk Factors in Hospitalized Patients with Coronary Artery Disease
(Arquivos Brasileiros de Cardiologia, 2002-09-01) [Artigo]
OBJECTIVE: To assess biochemical, anthropometric, and dietary variables considered risk factors for coronary artery disease. METHODS: Using anthropometrics, dietary allowance, and blood biochemistry, we assessed 84 patients ...
Effect of unsaturated fatty acids on myocardial performance, metabolism and morphology
(Brazilian Journal of Medical and Biological Research, 2006-02-01) [Artigo]
Diets rich in saturated fatty acids are one of the most important causes of atherosclerosis in men, and have been replaced with diets rich in unsaturated fatty acids (UFA) for the prevention of this disorder. However, the ...
Misclassification probability as obese or lean in hypercaloric and normocaloric diet
(Biological Research, 2008-01-01) [Artigo]
The aim of the present study was to determine the classification error probabilities, as lean or obese, in hypercaloric diet-induced obesity, which depends on the variable used to characterize animal obesity. In addition, ...
Down-regulation of the cardiac sarcoplasmic reticulum ryanodine channel in severely food-restricted rats
(Brazilian Journal of Medical and Biological Research, 2007-01-01) [Artigo]
We have shown that myocardial dysfunction induced by food restriction is related to calcium handling. Although cardiac function is depressed in food-restricted animals, there is limited information about the molecular ...
Obesity induces upregulation of genes involved in myocardial Ca2+ handling
(Brazilian Journal of Medical and Biological Research, 2008-07-01) [Artigo]
Obesity is a complex multifactorial disorder that is often associated with cardiovascular diseases. Research on experimental models has suggested that cardiac dysfunction in obesity might be related to alterations in ...
