Human neutrophil polymorphonuclear leukocytes (PMN) were studied to determine the influence of cellular locomotion upon the redistribution and capping of concanavalin A (Con A). Con A was detected by fluorescence (using Con A conjugated to fluorescein isothiocyanate [Con A-FITC]), or on shadow-cast replicas (using Busycon canaliculatum hemocyanin as a marker for Con A). After labeling with Con ...

Changes in the levels of glycolytic intermediates, adenylates, phosphagen, and substrates and products of anaerobic metabolism were monitored over the initial hours of anaerobiosis in radular retractor muscle, foot muscle, ...

The roles of hormones, second messengers and pH in triggering or potentiating biochemical responses to anaerobiosis were evaluated using in vitro incubations of isolated muscle tissues (foot, radular retractor, ventricle) from the marine whelk Busycon canaliculatum (L.). Incubating tissues in vitro under anoxic conditions stimulated changes in muscle fmctose-2,6-bisphosphate levels and pyruvate...

objective: alpha-glucosidase, as a carbohydratase catalyses the liberation of alpha-glucose from the nonreducing end of some carbohydrates from foods in digestive tract.  consequently, retard absorption of glucose by the inhibition of carbohydrate hydrolyzing enzymes is one of the therapeutic approaches to decrease the postprandial hyperglycemia. recently, a great deal of attention has been pai...
