Introduction: Previous studies have shown that sesame oil affects memory and learning. In the present work, effect of a diet containing 10% sesame oil used during pregnancy was evaluated on short-term passive avoidance learning of offspring rats by Shuttle box. Methods: Female Wistar rats were divided into 2 groups (n = 9 each group). Control group consumed regular diet during pregnancy and...

There are several conflicting evidences showing the effect of morphine on learning and memory processes. In the present study the effect of chronic morphine administration on passive avoidance, active avoidance and spatial learning and memory of morphine dependent male rats using Passive Avoidance shuttle box and Morris Water Maze tasks were investigated, respectively. Male rats received morphi...

abstract: introduction: nitric oxide (no) is a retrograde messenger in hippocampal synaptic plasticity which involves in learning and memory processes. previous studies revealed that hippocampal pyramidal cells contain no synthase (nos) enzyme which produce no and could be a promising target to evaluate the role of no in brain cognitive functions. so in this study, using nos inhibitor (l-name),...

Introduction: The interaction between steroid hormones and neurotransmitters such as GABA has been proved. The regulation of muscimol binding to high-affinity GABAA receptors by estradiol and progesterone has been studied within distinct brain regions using in vitro quantitative autoradiography. There are few studies about the mechanism of the effect of steroid hormones on behaviors such as ...

introduction: exposure to 3, 4- methylenedioxymethamphetamine (mdma) could lead to serotonergic system toxicity in the brain. this system is responsible for learning and memory functions. studies show that mdma causes memory impairment dose-dependently and acutely. the present study was designed to evaluate the chronic and acute effects of mdmd on spatial memory and acquisition of passive avoid...

Introduction: Cholinergic neuronal deficiency is one of the main causes of Alzheimer's pathology, which leads to learning and memory impairment. Scopolamine is a muscarinic cholinergic antagonist commonly used to induce Alzheimer's disease (AD). Insulin also regulates learning and memory function. Thus, the aim of this study was to determine the effect of central administration of insulin on pa...

introduction: previous studies have shown that sesame oil affects memory and learning. in the present work, effect of a diet containing 10% sesame oil used during pregnancy was evaluated on short-term passive avoidance learning of offspring rats by shuttle box. methods: female wistar rats were divided into 2 groups (n = 9 each group). control group consumed regular diet during pregnancy and the...

background: human beings use different approaches to learning. thus the aim of this study is to explore the mechanisms of learning through the hidden curriculum in the perspective of baccalaureate undergraduate nursing students. methods: this qualitative study, involving 24 baccalaureate undergraduate nursing students, was done by purposeful sampling strategies. the data were collected using se...

Introduction: Butylated hydroxytoluene (BHT 2, 6-di-tert-butyl-p-cresol) is one of the extensively used antioxidants in the food industry. It is used in low-fat foods, fish products, packaging materials, paraffin, and mineral oils. BHT is also widely used in combination with other antioxidants such as BHA, propyl gallate, and citric acid for the stabilization of oils and high-fat foods. On t...
