mals, and they have various physiological roles. D-Aspartate is present in the central nervous system and various neuroendocrine cells, which include a subset of satellite and basket cells in the cerebellum, adrenal chromaffin cells, pituitary gland cells, Leydig cells and pinealocytes. D-Aspartate is believed to modulate neuroendocrine functions in either an intercellular or intracellular mann...

The remarkably wide dynamic range of the chemotactic pathway of Escherichia coli, a model signal transduction system, is achieved by methylation/amidation of the transmembrane chemoreceptors that regulate the histidine kinase CheA in response to extracellular stimuli. The chemoreceptors cluster at a cell pole together with CheA and the adaptor CheW. Several lines of evidence have led to models ...

The effects of trazodone on the cyclic GMP elevation elicited by N-methyl-D-aspartate in rat cerebellar slices were analyzed. Trazodone inhibited in a concentration-dependent manner (EC50 = 0.82 nM) the cyclic GMP response evoked by 0.1 microM N-methyl-D-aspartate. The inhibition was near complete at 10 nM trazodone. The effect of 10 nM trazodone was unaffected by 0.3 microM spiperone or rauwol...

The current emergence of novel coronavirus, SARS-CoV-2 and its ceaseless expansion worldwide has posed a global health emergency that adversely affected the humans. With entire world striving to understand newly emerged virus, differences in morbidity infection rate have been observed across varied geographic areas, which ascribed viral mutation evolution over time. homotrimeric Spike (S) glyco...

BACKGROUND The present study examined the effect of P2X receptor antagonist 2',3'-O-(2,4,6-trinitrophenyl) adenosine 5'-triphosphate (TNP-ATP) on morphine tolerance in rats. METHODS Male Wistar rats were implanted with two intrathecal catheters with or without a microdialysis probe, then received a continuous intrathecal infusion of saline (control) or morphine (tolerance induction) for 5 day...
