Antidepressivo em ratos com insuficiência aórtica pode modificar a expressão gênica de ocitocina e vasopressina centrais?
(Universidade Estadual Paulista (Unesp), 2012)
Aortic regurgitation (AR) leads to a left ventricle dilation and hypertrophy in response to a chronic volume overload. It is still very frequent in developing countries, for instance Brazil, and often as secondary to ...
Toxicidade do metilmercúrio durante o desenvolvimento do coração: uma abordagem celular e tecidual utilizando embriões de gallus domesticus como modelo experimental
(2019)
O metilmercúrio (MeHg), forma mais tóxica do mercúrio orgânico, está associado a danos morfológicos, metabólicos e comportamentais nos indivíduos expostos. A neurotoxicidade do MeHg é um fenômeno bem documentado. No entanto, ...
Micro-Positron Emission Tomography in the Evaluation of Trypanosoma cruzi-Induced Heart Disease: Comparison with Other Modalities
(AMER SOC TROP MED & HYGIENE, 2009)
Noninvasive assessment of cardiac structure and function is essential to understand the natural course of murine infection with Trypanosoma cruzi. Magnetic resonance imaging (MRI) and echocardiography have been used to ...
Changes in total and transmural coronary blood flow induced by ethanol
(1983)
We studied the effects of ethanol on total coronary resistance and on the resistance across the left ventricular wall in the isolated empty beating heart of the dog. The coronaries were perfused with homologous fresh blood, ...
Infiltrative cardiomyopathies. Contribution of echocardiography
Infiltrative cardiomyopathies are characterised by the deposit of abnormal substances within the ventricular wall that cause stiffness and thus progressive diastolic dysfunction, which typically precedes systolic dysfunction. ...
Myocardial remodeling and dysfunction are induced by chronic food restriction in spontaneously hypertensive rats
(Elsevier B.V., 2006-11-01)
Several studies have shown alterations in hearts from animals subjected to food restriction (FR). However, few experiments in hearts evaluating pressure overload have been reported. We examined the effects of chronic FR ...
[Hydrocephaly does not modify neuroblast chain migration in the subventricular zone (SVZ)]
(2012)
BACKGROUND: Genetic mutations that affect cilia beating have shown that ependymal cilia not only contribute to the movement of cerebrospinal fluid, but also to direct migratory neuroblasts in the subventricular zone. These ...

Association Between Left Ventricle Diastolic Dysfunction and Unfavorable Prognostic Markers in Patients with Aortic Insufficiency
(Premchand Shantidevi Research Foundation, 2017-06-01)
Introduction: The presence of symptoms, systolic dysfunction and Left Ventricle (LV) dilation are considered unfavourable prognostic markers in Aortic Valve Insufficiency (AVI). The role of diastolic dysfunction, which is ...
