Los transportadores iónicos de la membrana plasmática son proteínas integrales que regulan diversas funciones celulares, como la composición iónica, el volumen y el pH intracelular (pHi). En células epiteliales, además, estos sistemas de transporte llevan a cabo el movimiento transepitelial de electrolitos.|

Los trastornos de la conducta alimentaria (TCA) engloban a una serie de enfermedades men- tales graves que cada vez afectan a más personas. Dentro de este trastorno encontramos varias enferme- dades, pero, todas tienen en común que presentan una alteración en la conducta alimentaria. Las más importantes son anorexia nerviosa, bulimia nerviosa y...

This study was undertaken to investigate the presence of a Na+{single bond}H+ antiporter in brush-border membrane vesicles (BBMV) isolated from chick small intestine. An outwardly directed proton gradient (pH 5.5 inside, 7.5 outside) stimulated Na+ uptake into BBMV and resulted in a transient accumulation. No accumulation was observed in the...

The low renal excretion of betaine indicates that the kidney efficiently reabsorbs the betaine filtered by the glomeruli but the mechanisms involved in such a process have been scarcely investigated. We have detected concentrative and non-concentrative betaine transport activity in brush-border membrane vesicles (BBMV) from rat renal cortex and...

El objetivo de este proyecto ha sido analizar los resultados obtenidos en el desarrollo de una nueva metodología docente en la enseñanza de Fisiopatología, asignatura troncal impartida en tercer curso de la Licenciatura de Farmacia de la Universidad de Sevilla. El número de estudiantes es de 548 repartidos en 4 grupos. El proyecto implica la...

D-mannose transport and metabolism has been studied in enterocytes isolated from chicken small intestine. In the presence of Na+, the mannose taken up by the cells either remains free, is phosphorylated, is catabolized to H2O, or becomes part of membrane components. The mannose remaining free in the cytosol is released when the cells are...

Among the types of muscles present in the body is skeletal muscle, which is the one that allows the development of physical activity thanks to the contractile activity of its muscle cells. It is known that physical exercise involves the release of plasma, by the skeletal muscle, of molecules called myokines as a result of muscle contraction....

Background/purpose Many studies suggest that insulin resistance in obese patients bridges mental illness. Our objective was to identify the association between levels of depression and anxiety with insulin resistance, and its relationship with obesity and abdominal obesity Methods A cross-sectional analytical study was carried out in Honduras....

Since 1956, when Harman first postulated the free radical theory of aging, numerous studies have been carried out to test the protective action of antioxidants. One of these protective compounds used in antioxidant therapy is folic acid (FA). Folate deficiency can lead to several pathologies and its protective role is very well known. Because...
