background: pioglitazone from thiazolidinediones generation, represent a new antidiabetic drugs that have been introduced in the world recently. thiazolidinediones can improve insulin resistance by activating the nuclear peroxoxisome proliferator activated receptor-γ (ppar-γ) and increasing insulin sensitivity in their receptors. insulin and its receptors are found in specific areas of cns with...

Purpose of the Study: Textured soy protein (TSP) and Ajil are two processed forms of soybean (Glycine max L.) which are widely consumed by Iranian for nutritional purpose. Recently, we have reported antioxidant and anticholinesterse effect of raw soybean (RS) which has been attributed to isoflavones such as genistein. In this work, we aimed to compare in vitro antioxidant and antichoinesterase ...

There is strong evidence that two cerebral hemispheres are differentially involved in emotional memory and that amygdala is a key subcortical structure for emotional experience. The present research investigated the possible involvement of lateralization of basolateral amygdala (BLA) and central amygdala (CEA) in place avoidance memory. For this purpose, male Long-Evans rats (280-320 g) were im...

Objective(s): Bisphenol A (BPA), a xenoestrogenic endocrine disrupting agent, is widely used in the production of polycarbonate plastics and has potential adverse effects on the developing nervous system, memory and learning abilities. The protective effect of the crocin, an important active constituent in Crocus sativus L, on memory impairment induced by BPA in rat wa...

previous studies have shown that caffeine has beneficial effects on cognitive impairment in sleep deprived male rats. therefore in the present study, we examined the effects of chronic caffeine administration on learning and memory impairments induced by sleep deprivation (sd) in the intact and ovarectomized (ovx) female rats. two sets of animals including intact and ovx were randomly recruited...

Introduction: Previous studies have shown that vitamin A and its derivatives such as retinoid and all-trans retinoic acid have a crucial role in memory, learning and synaptic plasticity. The receptors of vitamin A are seen in different parts of the brain such as hippocampus, where vitamin A has an important role in learning. In this study, the effect of intrahippocampal (CA1) injection of al...
