Dopamine concentration abnormalities in the body can cause various disorders and diseases such as Parkinson's, Tourette's syndrome, depression. In this study, graphene oxide (GO) was combined with Fe3O4 to sensitively selectively detect dopamine. The performance evaluated by cyclic voltammetry (CV) differential pulse (DPV) methods. results of testing CV on solution [Fe(CN)6] showed that a modif...

The last decade witnessed remarkable advances in our knowledge of the gustatory system. Application of molecular biology techniques not only determined the identity of the membrane receptors and downstream effectors that mediate sweetness, but also uncovered the overall logic of gustatory coding in the periphery. However, while the ability to taste sweet may offer the obvious advantage of elici...

background: metabolic syndrome (mets) is a complex clustering cardiovascular risk factors such as abdominal obesity, hypertension, diabetes and dyslipidemia. it has been a growing health problem in iranian adults in recent decade. the objective of this article was to review the prevalence of mets and the corresponding risk factors among iranian adults.methods: we conducted a systematic review t...

Use of space by both humans and other mammals should reflect underlying physiological, ecological, and behavioral processes. In particular, the space used by an individual for its normal activities should reflect the interplay of three constraints: (i) metabolic resource demand, (ii) environmental resource supply, and (iii) social behaviors that determine the extent to which space is used exclu...

background: release of vascular endothelial growth factor (vegf) by ovaries in response to hcg administration is one of the main mechanisms of ovarian hyper stimulation syndrome. since dopamine/dopamine receptor2 (dp-r2) pathway activity -mediated by vegf/ vascular endothelial growth factor receptor 2 (vegfr-2) signaling-, is associated with angiogenic events, dopamine agonists were used for th...

Although neuroimaging investigations in human cocaine abusers have provided important insights into the brain changes that accompany drug use, the interpretation of reports in human abusers can be very difficult. Studies in nonhuman primates provide a way to systematically evaluate the structural and functional adaptations engendered by cocaine self-administration without the confounds of human...
