abstract the lack of water is the most important problem in extensive landscape especially turfgrass in arid and semi arid regions. the root responses in native and commercial grasses under drought stress were investigated. this experiment was in a factorial experiment based on unbalanced completely random design on the year 2006. the specious that we used in this experiment included (i) commer...

morphine’s effects on learning and memory processes are well known to depend on synaptic plasticity in the hippocampus. whereas the role of the hippocampus in morphine-induced amnesia and state-dependent learning is established, the biochemical and molecular mechanisms underlying these processes are poorly understood. the present study intended to investigate whether administration of morphine ...

aim and background: pain is a complex experience involving psychological factors which results in functional disorder. this study aimed to analyze the correlation between cognitive and emotional factors with chronic low back pain among women in isfahan, iran. methods and materials: in this cross-sectional research, the target population included all women with chronic low back pain that referre...

Objective(s): Auraptene (7-geranyloxycoumarin) (AUR), from Citrus species has shown anti-inflammatory, neuroprotective, and acetylcholinesterase (AChE) and beta-secretase inhibitory effects. Scopolamine is a nonselective muscarinic receptor antagonist which causes short-term memory impairments and is used for inducing animal model of Alzheimer’s disease (AD). This research aimed to investigate ...

Active avoidance involving controlling and modifying threatening situations characterizes many forms of clinical pathology, particularly childhood anxiety. Presently our understanding of the neural systems supporting human avoidance is largely based on nonhuman research. Establishing the generality of nonhuman findings to healthy children is a needed first step towards advancing developmental a...

objective(s) the present study aimed to investigate the effects of a fat soluble antioxidant, coenzyme q10 (coq10) and folic acid on learning and memory in the rats with intracerebroventricular injection of streptozotocin (icv-stz), an animal model of sporadic type of alzheimer's disease. materials and methods the lesion groups were injected bilaterally with icv-stz (1.5 mg/kg b.wt., in no...

background: alzheimer’s disease was known as a progressive neurodegenerative disorder in the elderly and is characterized by dementia and severe neuronal loss in the some regions of brain such as nucleus basalis magnocellularis. it plays an important role in the brain functions such as learning and memory. loss of cholinergic neurons of nucleus basalis magnocellularis by ibotenic acid can commo...

introduction: zinc is an essential trace element that plays an important role in synaptic plasticity and modulating the activity of cns and involve in learning and memory. synaptic vesicle zinc in the hippocampus area exerting modulatory effects on nmda glutamate receptor. method: in this experiment the effects of nmda agonist and antagonist administration intra hippocampus on passive avoidance...

conclusions it can be concluded that the devisable memory-enhancing effects of red lentil (lens culinaris) are due to the antioxidant activity of its flavonoid, tannins, and terpenoids. background since ancient times, people have believed that certain foods or plants can affect learning and memory potency in humans. the consumption of food and beverages rich in flavonoid compounds has been prop...

a b s t r a c t introduction: diabetes mellitus is accompanied with disturbances in learning, memory, and cognitive skills in the human society and experimental animals. due to anti-diabetic and antioxidant activity of rumex patientia (rp), this research study was conducted to evaluate the efficacy of chronic rumex patientia feeding on alleviation of learning and memory disturbance in streptozo...
