introduction: many people with amnesia would like to try herbal therapies. ginkgo biloba is one of the most popular herbs which is used to treat amnesia. the beneficial effects of this plant, however, has not been scientifically assessed yet. although, there have been some reports on the memory enhancement effect of ginkgo biloba, the mechanism of its action is not yet explained well. consideri...

introduction: activation of n-methyl-d-aspartate (nmda) glutamate receptors in the nucleus accumbens is a component of drug-induced reward mechanism. in addition, nmda receptors play a major role in brain reward system and activation of these receptors can change firing pattern of dopamine neurons. blockade of glutamatergic neurotransmission reduces the expression of conditioned place preferenc...

introduction: n-methyl-d-aspartate (nmda) receptors play a pivotal role in the development of tolerance and physical dependence to opiates. activation of nmda receptors involves the induction of long term potentiation (ltp) in hippocampus. our previous study suggested that chronic oral administration of morphine enhanced nmda dependent ltp in the ca1 area of hippocampal slices of rats. the pres...

Activation of NMDA receptors involves the induction of long term potentiation (LTP) in hippocampus.

the n-methyl-d-aspartic acid (nmda) receptor is one of the specific types of ionotropic receptors which lied to glutaminergic system. it has been widely accepted that nmda receptor neurons promote anxiety, in humans as well as in animal models. however, in the previous study seems inhibiting of this receptors decreased the protective role in neural cell. demonstration of nmda receptor activity ...

In severe COVID-19 patients the blood level of autoantibodies (IgG) to neurospecific proteins was determined. It defined marked increase in peripheral myelin protein, protein lipid S100 type 2 dopamine receptors and dopamine. At same time, it designate relationship between levels NMDA receptors. High specific IgG SARS-CoV-2 S-Trimer Protein coincided with high

Costanza Angelini, Alessandro Morellato, Annalisa Alfieri, Lisa Pavinato, Tiziana Cravero, et al. (see pages [7183–7200][1]) The postsynaptic density (PSD) of excitatory synapses contains an extraordinary number proteins, including AMPA and NMDA receptors, accessory proteins that regulate

although the epileptogenic properties of estrogens have been widely demonstrated in several models and species, the mechanism(s) by which estrogens can acutely change seizure parameters including after discharge and seizure duration remain remains to be determined. in the present study, we examined the role of nmda (n-methyl-d-aspartate), non-nmda and estrogenic receptors in estradiol benzoate ...

Arginine-phenylalanine-amide (RFamide)-related peptides known as neuropeptide VF (NPVF) have a crucial role in feeding regulation. The present study purposed to determine the effect of intracerebroventricular (ICV) injection NPVF on dietary intake and possible interactions with glutamate opioid systems broiler chicken. In experiment 1, chickens received ICV administration control solution, (16 ...
