Effect of mercuric chloride on electrical parameters and anion fluxes in the toad skin
(Elsevier Science Inc, 2005-12)
The amphibian skin, widely used for studying the transepithelial passage of electrolytes, exhibits anion pathways relatively specific for Cl-. We studied the effect of HgCl2, 1.0×10-4 M on its electrical parameters and ...
Modulation by extracellular Cl- of volume-activated organic osmolyte and halide permeabilities in HeLa cells
(1997)
Organic osmolyte and halide permeabil-ity pathways activated in epithelial HeLa cells by osmotically induced cell swelling were studied using electrophysiological and radiotracer efflux techniques. On hypotonie challenge, ...

The effects of lipopolysaccharide-induced reactive oxygen species were blunted by calcium oxalate in renal tubular epithelial cells
(Karger, 2008-01-01)
Background/Aim: Previously we demonstrated that calcium oxalate ( CaOx) in LLC-PK1 cells and oxalate in MDCK cells induce tubular damage and greater glycosaminoglycan synthesis. We test the hypothesis that reactive oxygen ...
Fluid transport across leaky epithelia: Central role of the tight junction and supporting role of aquaporins
(American Physiological Society, 2010-10)
The mechanism of epithelial fluid transport remains unsolved, which is partly due to inherent experimental difficulties. However, a preparation with which our laboratory works, the corneal endothelium, is a simple leaky ...
Contribución a la caracterización biofarmacéutica de un extracto de hojas de Passiflora ligularis (granadilla) optimizado en flavonoides
(Universidad Nacional de ColombiaBogotá - Ciencias - Maestría en Ciencias FarmacéuticasDepartamento de FarmaciaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2021)
Passiflora ligularis, comúnmente conocida como granadilla, es una especie que ha demostrado resultados prometedores de actividad hipoglicemiante/antidiabética. Con el presente trabajo, se aplicó la utilidad del Sistema de ...
Estudio de las propiedades fisicoquímicas y antimicóticas de complejos entre un polielectrolito y el ácido benzoico como molécula modelo
(Departamento de FarmaciaUniversidad Nacional de Colombia - Sede Bogotá, 2019-03-15)
La interacción de polielectrolitos con contraiones de uso farmacéutico ha sido aprovechada con múltiples propósitos, tales como la modulación de liberación, aumento de estabilidad de activos e incluso como potenciador de ...
