The serotonin type IA (5-HT1A) receptors are members of a superfamily of seven transmembrane domain receptors that couple to GTP binding regulatory proteins (G-proteins). Serotonergic signalling has been shown to play an important role in alcohol tolerance and dependence. We have studied the effects of alcohols on ligand (agonist and antagonist) binding to bovine hippocampal 5-HT1A receptor in ...

A variety of clinical observations suggest that certain forms of epilepsy are due to long-term, progressive changes in neural networks that eventually provoke spontaneous and recurring seizures. Recently, there has been growing evidence that serotonergic neurotransmission modulates experimentally induced seizures and is involved in the enhanced seizure susceptibility observed in some geneticall...

background: general concern is that the pregnancy rate is higher with gnrh-agonist as a protocol of pituitary suppression. gnrh-antagonist protocol provides a shorter period of administration and an easy flexible protocol. objective: in this study, the outcomes of gnrh agonist and antagonist in icsi cycles are compared in normo responder patients. materials and methods: in this randomized clini...
