Mujer de 27 años proveniente de zona rural en Jalisco, fue ingresada al hospital por náusea, vómito y dolor abdominal. Un mes previo presentó cuadros de dolor abdominal en epigastrio, ardoroso y en cuadrante superior derecho con distensión abdominal. Los análisis de laboratorio con enzimas hepáticas alteradas con patrón mixto (AST 64 UI/l; ALT 146 UI/l; GGT 185 UI/l; FA 188 UI/l), con nivel de ...

La afectación gastrointestinal por citomegalovirus (CMV) es cada vez más frecuente en los pacientes trasplantados en gran parte por la introducción en los últimos años de los inhibidores de las purinas1, pudiendo aparecer en cualquier momento de su evolución. La enfermedad invasiva severa por CMV es poco frecuente por el desarrollo de estrategias de prevención y tratamiento anticipado2, y se de...

In this paper, we associate canonically a precyclic mod- ule to a regular multiplier Hopf algebra endowed with a group-like projection and a modular pair in involution satisfying certain con- dition

The lectin concanavalin A (Con A) was used as a model probe to study the behavior of molecules bound to the surface of recently transformed schistosomula of Schistosoma mansoni. Con A binding was saturable (150-180 pg/organism) and specifically competed by alpha-methyl mannoside. Both FITC-Con A and 125-I-Con A were lost from the surface of schistosomula with a halftime of 8-10 h in culture in ...

The late B-cell proliferative phase of the in vitro antibody response by rabbit spleen cells is highly susceptible to suppression by activated T cells. The in vitro antisheep erythrocyte plaque-forming cell (PFC) response by spleen cells from normal or primed rabbits can be suppressed by adding concanavalin A (Con A), Con A-prestimulated peripheral blood or spleen lymphocytes, or supernates fro...

Conantokin G (Con G) is a 17-amino-acid peptide antagonist of N-methyl-D-aspartate (NMDA) receptors isolated from the venom of the marine cone snail, Conus geographus. The mechanism of action of Con G has not been well defined; both competitive and noncompetitive interactions with the NMDA-binding site have been proposed. In this study the mechanism of action and subunit selectivity of Con G wa...

Antecedentes/Objetivo: La excreción de endotelina-1 urinaria (UET-1) es mayor en pacientes con enfermedad renal de cualquier etiología, comparados con sujetos normales, por lo que ésta podría servir potencialmente como un marcador de daño renal. Metodología: Comparamos la excreción de UET-1 en 67 pacientes con diabetes tipo 2 (DM2) con y sin hipertensión (HTA), y en presencia o ausencia de micr...

Because of the central role of Concanavalin A (Con A) in the study of protein-carbohydrate interactions, a thorough understanding of the multivalent functions of Con A is imperative. Here, the association of monomeric and dimeric derivatives of Con A with mannose-functionalized generation two through six PAMAM dendrimers is reported. Hemagglutination assay results indicate relatively low activi...

1 Effects of concanavalin A (Con A) and other lectins on 5-hydroxytryptamine (5-HT) uptake by rabbit blood platelets and on their ultrastructure were studied. 2 Uptake of [3H]-5-HT by platelets was decreased by application of Con A, E-PHA (lectin from Phaseoltis vulgaris) and lentil-PHA (lectin from Lens culinaris), but not by wheat germ agglutinin (WGA). Con A induced specific changes in the u...

Cerebellar Purkinje cells contain intracellular membrane systems that are highly enriched in concanavalin A (Con A)-binding sites and which may be involved in axonal and dendritic transport. We have attempted to characterize these Con A-binding sites in fixed slices of cerebellum by their susceptibility to endoglycosidase H (Endo H) digestion. Tissue slices labeled with Con A-peroxidase without...
