Since the discovery of nitric oxide (NO) as a neuronal messenger, its way to modulate learning and memory functions is subject of intense research. NO is an intercellular messenger in the central nervous system and is formed on demand through the conversion of L-arginine to L-citrulline via the enzyme nitric oxide synthase (NOS). Neuronal form of nitric oxide synthase may play an important role...
Consider a complete weighted bipartite graph G in which each left vertex u has two real numbers intercept and slope, each right vertex v has a real number quality, and the weight of any edge (u, v) is defined as the intercept of u plus the slope of u times the quality of v. Let m (resp., n) denote the number of left (resp., right) vertices, and assume that m ≥ n. We develop a fast algorithm for...
To study the effect of organic Se on spatial learning and memory deficits induced by Pb exposure at different developmental stages, and its relationship with alterations of synaptic structural plasticity, postnatal rat pups were randomly divided into five groups: Control; Pb (Weaned pups were exposed to Pb at postnatal day (PND) 21-42); Pb-Se (Weaned pups were exposed to Se at PND 43-63 after P...
Numerous studies have demonstrated the antioxidant effects of grape seed proanthocyanidin extract (GSPE). The generation of free radicals and the ensuing apoptosis may contribute to the pathogenesis of epilepsy; therefore, in the present study, we examined the effects of GSPE on cognitive impairment and neuronal damage induced by chronic seizures in rats. Seizures were induced by a daily intrap...
Agomelatine, a novel antidepressant with established clinical efficacy, acts as an agonist of melatonergic MT1 and MT2 receptors and as an antagonist of 5-HT2C receptors. The present study was undertaken to investigate whether chronic treatment with agomelatine would block unpredictable chronic mild stress (UCMS)-induced cognitive deterioration in mice in passive avoidance (PA), modified elevat...
BACKGROUND Cognitive impairment is a severe complication caused by obstructive sleep apnea (OSA). The mechanisms of causation are still unclear. The Wnt/β-catenin signaling pathway is involved in cognition, and abnormalities in it are implicated in neurological disorders. Here, we explored the Wnt/β-catenin signaling pathway abnormalities caused by chronic intermittent hypoxia (CIH), the most c...
BACKGROUND The aim of this study was to investigate the effects of a potent nitric oxide-guanylate cyclase activator, 3-(5'-hydroxymethyl-2'-furyl)-1-benzylindazole (YC-1), on learning and memory functions in aged rats. MATERIAL AND METHODS Rats were divided into 2 groups as 4-month-old and 24-month-old rats. Rats received YC-1 (1 mg/kg/day) for 2 weeks long-term. Morris water maze (MWM) and ...
background: testosterone and its metabolites have important roles in learning and memory. the current study has conducted to assess the effect of pre-training, post-training and pre-probe trial intrahippocampal ca1 administration of 3 alpha-anderostanediol (one of the metabolites of testosterone) and indomethacin (as 3 alpha-hydroxysteroid dehydrogenase enzyme blocker) on acquisition, consolida...
Purpose: Although a primary goal of many manual therapy techniques is to improve joint range of motion (ROM), efficacy studies evaluating the effect of treatment on ROM are limited. The purpose of this study was to evaluate the effect of a talocrural joint mobilization-with-movement (MWM) technique on dorsiflexion ROM in participants demonstrating decreased range following lateral
A 56-days experiment was carried out to study the effect of replacing macaroni waste meal (MWM) with maize on nutrient digestibility and blood chemistry indigenous turkey starter. Ninety-six poults an average weight 52 g were randomly assigned four dietary treatments containing at 0%, 15%, 30% 45% level as replacement for maize. Each treatment consist 24 replicated thrice 8 turkeys per replicat...
