objective: the influence of cholinergic drugs on lithium-induced statedependent learning has been investigated in adult male mice. method: a single-trial step-down inhibitory avoidance task was selected. the drugs used in the study were lithium chloride physostigmine , nicotine hydrogen tartrate and scopolamine hydrobromide, atropine sulphate. the drugs were administrated through the peritoneal...

the present study was undertaken to investigate the beneficial effects of widely-prescribed lipid lowering drugs, pitavastatin, atorvastatin and simvastatin 3-hydroxy-3-methylglutaryl-coenzyme-a (hmg-coa) reductase inhibitors in cognitive dysfunctions of mice. intra-cerebroventricular (icv)-streptozocin-(stz)- and high-fat diet (hfd)-induced amnesia served as interoceptive memory models where a...

introduction: previous studies have indicated that stress levels of glucocorticoid hormones induce impairment of long term memory retrieval, but the underlying mechanisms (genomic or non-genomic) are not clear. to clarify this issue, we investigated the involvement of brain corticosteroid receptors and protein synthesis in the glucocorticoid-induced impairment of memory retrieval. methods: 140 ...

Parent involvement (PI) in school is associated with more positive academic performance and social competence in children. However, there are inadequacies in current measures of PI and a need for a better understanding of predictors of PI. In this study, measures were obtained from a normative sample of 387 children in kindergarten and first grade from high-risk neighborhoods in 4 different sit...

Self-assessment and task-based assessment have recently attracted attention in language learning and testing contexts worldwide; however, little research has been carried out to document the link between these notions. The present research was an attempt to investigate the connection between task-free/task-based self-assessment and learners’ self-perceived communicative competence in speaking. ...
