Effect of CRH on NO bioavailability, ROS production and antioxidant defense systems in endothelial EAhy926 cells
(2010)Local or 'Immune' Corticotropin-Releasing Hormone (CRH) is secreted in peripheral tissues and plays a direct immunomodulatory role as an endocrine or paracrine mediator of inflammation. The present study was undertaken to ... -
The nitric oxide (NO) donor molsidomine antagonizes scopolamine and L-NAME-induced performance deficits in a spatial memory task in the rat
(2009)Nitric oxide (NO) is considered as an intracellular messenger in the brain. Its involvement in learning and memory processes has been proposed. Compounds that inhibit NO synthase (NOS), the key synthesizing enzyme, may ... -
Nitric oxide donor molsidomine attenuates psychotomimetic effects of the NMDA receptor antagonist MK-801
(2006)There is experimental evidence indicating that the noncompetitive NMDA receptor antagonist MK-801 impairs cognition and produces a series of schizophrenia-like symptoms in rodents (hypermotility, stereotypies, and ataxia). ... -
Plasma Indoleamine 2,3-Dioxygenase and Arginase Type I May Contribute to Decreased Blood T-Cell Count in Hemodialysis Patients
(2012)Background: Acquired immunity is impaired in hemodialysis (HD) patients, and decreased T-cell number may contribute. Indoleamine 2,3-dioxygenase (IDO) and arginase type I (ARG) catabolize tryptophane and arginine, respectively, ... -
Repeated administration of the nitric oxide synthase inhibitor L-NAME differentially affects rats' recognition memory
(2011)Nitric oxide (NO) is sought to be an intracellular messenger in the central nervous system and its implication in learning and memory is well documented. Compounds that inhibit nitric oxide synthase (NOS), the key synthesizing ... -
Resting tension affects eNOS activity in a calcium- dependent way in airways
(2007)The alteration of resting tension (RT) from 0.5 g to 2.5 g increased significantly airway smooth muscle contractions induced by acetylcholine (ACh) in rabbit trachea. The decrease in extracellular calcium concentration ... -
The role of nitric oxide in the object recognition memory
(2015)The novel object recognition task (NORT) assesses recognition memory in animals. It is a non-rewarded paradigm that it is based on spontaneous exploratory behavior in rodents. This procedure is widely used for testing the ...
