background: sporadic alzheimer’s disease (sad) is caused by genetic risk factors, aging and oxidative stresses. the herbal extract of rosa canina (r. canina), tanacetum vulgare (t. vulgare) and urtica dioica (u. dioica) has a beneficial role in aging, as an anti-inflammatory and anti-oxidative agent. in this study, the neuroprotective effects of this herbal extract in the rat model of sad was i...
background: alpha methyldopa (amd) is a well-known treatment for the pregnancy induced hypertension and commonly used in several countries. indeed the possible effect of amd on the behavioral activities of offspring, whom are exposed during fetus period, has not been studied. the present study evaluated the possible effect of maternal administration of amd on the rat offspring memory in the gro...
Introduction: Sleep disorders are common problems in modern societies affecting different aspects of individuals' lives. Many studies have reported that sleep deprivation (SD) leads to impairments in hippocampus-dependent learning and memory formations. Physical exercise has been shown to improve learning and memory. The objective of the current study was to investigate the effects of Voluntary...
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...
nitric oxide (no) is thought to be involved in spatial learning and memory in several brain areas such as hippocampus. this study examined the effects of post-training intrahippocampal microinjections of 1400w as a selective inos inhibitor on spatial memory, in anesthetized and non-anesthetized situations in rats. in the present work, 4-day training trials of animals were conducted. spatial mem...
why some learners are willing to communicate in english, concurrently others are not, has been an intensive investigation in l2 education. willingness to communicate (wtc) proposed as initiating to communicate while given a choice has recently played a crucial role in l2 learning. it was hypothesized that wtc would be associated with language learning orientations (llos) as well as social suppo...
the effect of saffranal on intracerebroventricular strepto-zotocin-induced cognitive deficits in rat
background and objective: intracerebroventricular (icv) injection of streptozotocin (stz) causes cognitive impairment in rats. the beneficial effect of saffron main component, safranal was investigated on icv stz-induced learning, memory, and cognitive impairment in male rats. materials and methods: for this purpose, rats were injected with icv stz bilaterally, on days 1 and 3 (3 mg/kg). the st...
due to extraordinary large amount of information and daily sharp increasing claimant for ui benefits and because of serious constraint of financial barriers, the importance of handling fraud detection in order to discover, control and predict fraudulent claims is inevitable. we use the most appropriate data mining methodology, methods, techniques and tools to extract knowledge or insights from ...
this study investigated the potential role of age in inductive and deductive grammar learning among iranian foreign language learners. the experimental population consisted of our randomly selected samples including two groups of children (with age of exposure to english within 8-13), and two groups of adults (with age of exposure to english within 11-13). thus, the comparison was between ch...
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
