(Universidad de Guayaquil. Facultad de Ciencias Médicas. Carrera de Medicina, 2020)
Las miocardiopatías son patologías que afectan al miocardio tanto estructural como funcionalmente, y en ausencias de otras patologías o síndromes cardiovasculares que pudieran explicar estas alteraciones, tales como ...
Expresión de la 11-B-hidroxilasa (CYP11B1) y aldosterona sintasa (CYP11B2) en musculo cardiaco de rata urémica tratada con pentoxifilina y bromocriptina
(2009-08-13)
RESUMEN: La aldosterona es un mineralocorticoide sintetizado entre la zona reticular y glomerulosa de la glándula adrenal, en estado normal se encarga de la regulación de los electrolitos y agua en el espacio extracelular. ...
Aspectos estruturais e moleculares do músculo cardíaco durante a transição entre a disfunção e a insuficiência cardiaca
(Universidade Estadual Paulista (Unesp), 2015-03-26)
Cardiac remodeling (CR) is a time-dependent process that promotes cellular and molecular changes manifested clinically by changes in size, shape and function after injury, and heart failure (HF), the final stage of the ...
Role of CaMKII and ROS in rapid pacing-induced apoptosis
(Elsevier, 2013-10)
Tachycardia promotes cell death and cardiac remodeling, leading to congestive heart failure. However, the underlying mechanism of tachycardia- or rapid pacing (RP)-induced cell death remains unknown. Myocyte loss by apoptosis ...
Time course of hydrogen peroxide-thioredoxin balance and its influence on the intracellular signalling in myocardial infarction
(WILEY-BLACKWELLHOBOKEN, 2012)
We investigated the myocardial thioredoxin-1 and hydrogen peroxide concentrations and their association with some prosurvival and pro-apoptotic proteins, during the transition from myocardial infarction (MI) to heart failure ...
Role of Mitochondrial Dysfunction in Hypertension and Obesity
(Current Medicine Group, 2017-02)
Mitochondria are essential for the maintenance of normal physiological function of tissue cells. Mitochondria are subject to dynamic processes in order to establish a control system related to survival or cell death and ...
Cellular basis of pineal gland development: Emerging role of microglia as phenotype regulator
(Public Library of Science, 2016-11)
The adult pineal gland is composed of pinealocytes, astrocytes, microglia, and other interstitial cells that have been described in detail. However, factors that contribute to pineal development have not been fully elucidated, ...
PHYSIOLOGICAL MULTIVALVULAR REGURGITATION DURING PREGNANCY - A LONGITUDINAL DOPPLER-ECHOCARDIOGRAPHIC STUDY
(Elsevier B.V., 1993-07-15)
Valvular function, assessed by Doppler technique, has not been extensively investigated during normal pregnancy. To prospectively study this feature, 18 normal pregnant women were followed during their pregnancies and ...
Niveles aumentados de estrés oxidativo se asocian a disfunción endotelial periférica y respuesta vascular pulmonar disminuida frente a vasodilatadores en pacientes con hipertensión pulmonar
(2010)
Background: Pulmonary Arterial Hypertension (PAH) is characterized by endothelial dysfunction and vascular remodeling. Several lines of experimental evidence indícate that oxidative stress plays an important role in the ...
Modification of cardiac biomarkers sensity in hypertensive patiens treated with angiotensin-converting enzyme inhibitors in acute coronary syndrome with non-st segment elevation
(International Knowledge Press, 2019-06)
Background: Patients with non-ST segment elevation myocardial infarction and the mortality risk is associated when Creatine Kinase isoenzyme MB and Troponin I values are increase. Objective: The present study was oriented ...
