Amphetamine, a potent sympathomimetic amine, has powerful stimulant actions in the central nervous system. These actions are believed to be related to the influence of amphetamine on release and uptake of catecholamine neurotransmitters. The ['4C]deoxyglucose method makes it possible to study changes in cerebral metabolic rate in different areas of gray and white matter. Because of the close re...

The predominant biological hypothesis for a neurochemical defect in schizophrenia is currently the socalled "dopamine (DA) hypothesis." In its simplest form, this hypothesis states that schizophrenia may be related to a relative excess of DA-dependent neuronal activity. It is derived from pharmacologic evidence that drugs that decrease DA activity (e.g., the phenothiazines) may be antipsychotic...

the estimation of instantaneous peak discharge is important for watershed management because there is ainsufficient climatic and hydrologic data in countries such as iran. researchers have been forced to link constantparameters (geomorphology) and variable parameters (hydrology) to models with minimum dependence on climaticand hydrologic data for hydrologic estimation. the present study used a ...

Stanford Genetics Professor Michael Snyder’s book, Genomics & Personalized Medicine: What Everyone Needs to Know, is a work to be enjoyed on multiple levels. Designed for a broad audience, the book delivers a great deal of detail for the scientifically savvy while still providing a generalized overview for the yet-to-be-initiated. Although brief, the book is timely, having followed closely on t...
