PURPOSE Because several polypeptide growth factors are known to influence capillary endothelial cell mitogenesis, the authors investigated the presence of some of these molecules in choroidal neovascular membranes (CNVMs) removed surgically from human subjects with age-related macular degeneration (ARMD). METHODS The authors performed immunoelectron(More)
PURPOSE To determine whether vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF), which have been implicated in the development of retinal and choroidal neovascularization, are present in the retinas and optic nerves of patients with diabetes before proliferative retinopathy appears. METHODS Light microscopic(More)
The possible involvement of subtypes of dopamine (DA) receptors in pecking induced by apomorphine (APO) in chicks was studied. D-1/D-2 agonist APO dose-dependently induced pecking in chicks. The APO response was decreased in animals pretreated with either the D-2 receptor antagonist sulpiride or the D-1 receptor antagonist SCH 23390. The inhibitory effects(More)
Multiple lines of evidence implicate the endocannabinoid signaling system in the modulation of metabolic disease. Genetic or pharmacological inactivation of CB1 in rodents leads to reduced body weight, resistance to diet-induced obesity, decreased intake of highly palatable food, and increased energy expenditure. Cannabinoid agonists stimulate feeding in(More)
