Ítem Modificaciones fisiológicas de la función endotelial tras un ejercicio intenso(Elsevier España, 2010-09-01) Ramirez Escobar, Jorge Hernan; robin640@hotmail.comEl ejercicio físico regular ejerce un efecto beneficioso sobre la función vascular de sujetos sedentarios y pacientes con enfermedad arterial coronaria1. El ejercicio físico incrementa el flujo sanguíneo y la tensión de roce o fricción de la sangre sobre el endotelio2,3 aumentando el óxido nítrico (NO) y favoreciendo la vasodilatación dependiente del endotelio (VDE)4,5. El propósito de este estudio ha sido describir los cambios en la función vascular tras un ejercicio físico prolongado e intenso (21km), en corredores no de élite.Ítem Relationship between maternal and newborn endothelial function and oxidative stress(Wiley, 2015-12-01) Echeverri, Isabella; Aguilar de Plata, Cecilia; Mateous, Julio César; Suárez Ortegon, Milton Fabian; Mosquera, Mildrey; Ortega Ávila, José Guillermo; Castillo Giraldo, Andrés Orlando; Jiménez, EliécerObjective To evaluate the Relationship between maternal and newborn endothelial function and oxidative stress. Methods Forty-three pregnant women and their offspring were evaluated. As markers of endothelial function, the flow-mediated dilation (FMD) was measured in pregnant women in the second and third trimesters, and nitric oxide (NO) was quantified in the endothelial cells of the umbilical cord vein. Malondialdehyde (MDA), as a marker of oxidative stress, was measured in the maternal plasma (second and third trimesters) and plasma from umbilical cord blood. Gestational age and birth weight were recorded. Correlations between variables were estimated, and adjustments were made for specific gestational week of measurement, gestational age at birth, and complications during pregnancy and/or at delivery.
