We examined Na(+)-K(+)-ATPase activity and the levels of alpha I-, alpha II-, and beta-subunit mRNA and protein in aortic cells of diabetic rats. Diabetes was induced by streptozocin. Na(+)-K(+)-ATPase activity was significantly reduced on the 2nd day of diabetes (9.4 +/- 1.3 vs. 17.5 +/- 2.1 mumol NADH.mg-1 protein.h-1, P less than 0.05) and remained(More)
This study sought to investigate the left hemisphere deficit hypothesis regarding autism. A group of 15 autistic youngsters between the ages of 8 and 13 years was compared with a group of 15 mentally retarded youngsters matched for age and IQ on a set of measures presumed to be sensitive to neuropsychological dysfunction. The results suggested that this(More)
Eighty-seven percent of the total cellular pool of somatostatin (SRIF) receptors in pancreatic islets are located intracellularly. Upon glucose stimulation (300 mg/dl) of insulin release, 8-15% of intracellular SRIF receptors are translocated to the plasma membrane. Affinity of SRIF receptors does not change during their migration and the total cellular(More)
Catfish pancreatic somatostatin, which contains eight additional amino acids on the amino terminus of a tetradecapeptide with considerable homology to tetradecapeptide somatostatin (SRIF), is a naturally occurring homolog of the hypothalamic peptide. The purpose of these studies was to determine the biological activity of this somatostatin homolog.(More)
