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 p...
A single Memory impairment substantially reduces the quality of life in elderly. It is associated with thealteration neurotrophic (NT) factors, such as brain-derived factor (BDNF) and glutamatereceptor N-methyl-D-aspartate (NMDA). Exercise often used to reduce cognitive impairment. Previousstudies show that benefits aerobic exercises on impairments are correlated increasing BDNFand preventing p...
conclusions our findings support the role of nmdars in pregabalin antinociception, because the nmdar agonist, unlike the antagonist, decreased the antinociceptive effect of pregabalin, even if tail flick is not an adequate pain assessment method in this regard. background pregabalin as a new anticonvulsant has been used in different pain treatments. objectives the aim of this study was to inves...
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 ...
long-term potentiation (ltp) is a reflection of synaptic plasticity that induced by specific patterns of synaptic activity and has an important role in learning and memory. the first clue of the potential role of glutamate receptors in ltp was in 1991 with the observation that the mglur agonists 1-amino-1, 3-cyclopentanedicarboxylic acid (acpd), increased ltp. studies have shown that acpd induc...
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 ...
introduction: the nucleus paragigantocellularis lateralis (lpgi) is involved in the descending pain modulation. the neurostreoid, 17β-estradiol found in the pgi nucleus and modulates nociception by binding to estrogen receptors and also by allosteric interaction with nmda receptors. in this study, the role of nmda receptors in the 17β-estradiol-induced pain modulation was investigated by assess...
سابقه و هدف: بیماری آلزایمر یک اختلال پیشرونده مغزی است که به تدریج حافظه، توانایی یادگیری، استدلال کردن، قضاوت، برقراری ارتباط و انجام فعالیتهای روزانه را مختل میکند. به هنگام پیشرفت بیماری آلزایمر، بیماران ممکن است تغییراتی در شخصیت و رفتار از قبیل اضطراب و تشویش، بدگمانی، آشفتگی و همچنین توهمات و خیالات را تجربه کنند. در حال حاضر، درمانی قطعی برای این بیماری وجود ندارد، اما درمانهای جدید...
