Resumen Introducción. El grupo de investigación del Laboratorio de Neurofisiología Comportamental de la Universidad Nacional de Colombia ha descrito modificaciones estructurales y electrofisiológicas en neuronas piramidales de la corteza motora producidas por la lesión del nervio facial contralater...

ABSTRACT Objectives: to evaluate, histologically and macroscopically, the influence of Copaifera multijuga (Copaíba) oil-resin on the healing process of cutaneous wounds, comparing it with nitrofurazone. Methods: we divided 36 rats into three groups of 12 animals, according to the treatment to be admi...
ABSTRACT Objective: to compare intraperitoneal adhesion formation in rats when using polypropylene and polypropylene with poliglecaprone meshes. Methods: we used twenty male, Wistar rats, divided in two groups. In group 1, the rats received the polypropylene mesh on their right side and the polypropyl...
In this study, we aim to examine effects of an experimentally induced unilateral varicose ovarian vein on the activities of anti-oxidant enzymes in an adult rat ovary. In this experimental study, a total of 30 adult female Wistar albino rats were divided into three groups. 10 rats in group 1 as the varic...
Kinins are vasoactive peptides that promote pain and inflammation, yet centrally believed to participate to cardiovascular defensive reflexes produced by noxious stimuli. These peptides signal through the activation of two transmembrane G-protein-coupled receptors named B1 and B2 receptors (B1R and B2R)....
ICAM-1 which is expressed by endothelial cells and leukocytes are observed as first markers in diseases such as transplant rejection, diabetes and atherosclerosis and in infections caused by various pathogens. In the present study, it is aimed to reveal the age-related changes in the expression of ICAM-1...
Estudios previos han demostrado que los bisfosfonatos son potentes inhibidores de la resorción ósea. El aceite de oliva (O) es rico en ácidos grasos monoinsaturados con potentes propiedades anti-oxidantes. El objetivo de este estudio fue estudiar el efecto del tratamiento de alendronato (AL) y pamidro...

ABSTRACT Objective The current study was aimed at analyzing sarcoplasmic reticulum Ca2+ ATPase (Serca2) and ryanodine receptor type 2 (Ryr2) gene expression in rats subjected to surgery that induced HF and were subsequently treated with T4 using physiological doses. Materials and methods HF was induc...

Abstract Introduction: Contrast-induced nephropathy (CIN) is a major iatrogenic cause of acute kidney injury. Experimental studies have shown that intravascular injection causes intense vacuolization of the contrast agent in the proximal renal tubules cells, preceding the increase in serum creatinine, a...
Abstract Background: Hyperthyroidism is currently recognized to affect the cardiovascular system, leading to a series of molecular and functional changes. However, little is known about the functional influence of hyperthyroidism in the regulation of cytoplasmic calcium and on the sodium/calcium exchang...
