To evaluate the pharmacological activity of insulin-loaded alginate/chitosan nanoparticles following oral dosage in diabetic rats. Nanoparticles were prepared by ionotropic pre-gelation of an alginate core followed by chitosan polyelectrolyte complexation. In vivo activity was evaluated by measuring the decrease in blood glucose concentrations in(More)
Dysregulation of glutamate has been described in depression, and supersensitivity of platelet glutamate receptors has been found in both psychotic major depression and schizophrenia. The aim of this study was to examine the platelet glutamate receptor sensitivity in patients with nonpsychotic, unipolar major depression to assess whether this is a marker of(More)
There is provisional evidence of involvement of adenosine in depression. In this study, the second messenger intracellular calcium response in platelets was measured in patients with major depression and controls using spectrofluorometry. The primary result of this study was a statistically significantly blunted second messenger response to agonist(More)
