Acute myocardial infarction delineated by noninvasive thallium-201/technetium-99m pyrophosphate tomography.

abstract：:Alzheimer's disease is associated with a loss in presynaptic cholinergic function. It has been suggested that cholinergic inhibitors such as donepezil hydrochloride (Donepezil) could restore this function and improve some of the symptoms of Alzheimer's disease. Previous work has shown that Donepezil improves cognitive...
