Martinez PF, Okoshi K, Zornoff LA, Oliveira Jr SA, Campos DH, Lima AR, Damatto RL, Cezar MD, Bonomo C, Guizoni DM, Padovani CR, Cicogna AC, Okoshi MP. Echocardiographic detection of congestive heart failure in postinfarction ...
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 ...
Disfunção miocárdica e alterações no trânsito de cálcio intracelular em ratos obesos
(Arquivos Brasileiros de Cardiologia, 2011-09-01) [Artigo]
FUNDAMENTO: Vários mecanismos têm sido propostos contribuir para a disfunção cardíaca em modelos de obesidade, tais como alterações nas proteínas do trânsito de cálcio (Ca+2) e nos receptores beta-adrenérgicos. Todavia, o ...
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 ...
Multivariate analysis for animal selection in experimental research
(Arquivos Brasileiros de Cardiologia, 2015-02-01) [Artigo]
Background: Several researchers seek methods for the selection of homogeneous groups of animals in experimental studies, a fact justified because homogeneity is an indispensable prerequisite for casualization of treatments. ...
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, ...
A comparative study of myocardial function and morphology during fasting/refeeding and food restriction in rats
(Cardiovascular Pathology, 2010-09-01) [Artigo]
Background: This study compared the influence of fasting/refeeding cycles and food restriction on rat myocardial performance and morphology. Methods: Sixty-day-old male Wistar rats were submitted to food ad libitum (C), ...
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 ...
Effects of protein-calorie restriction on mechanical function of hypertrophied cardiac muscle
(Arquivos Brasileiros de Cardiologia, 1999-04-01) [Artigo]
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 ...
