[ 1 ] - Acute stress does not affect the impairing effect of chronic stress on memory retrieval
Objective(s): Due to the prevalence and pervasiveness of stress in modern life and exposure to both chronic and acute stresses, it is not clear whether prior exposure to chronic stress can influence the impairing effects of acute stress on memory retrieval. This issue was tested in this study. Materials and Methods: Adult male Wistar rats were randomly assigned to the following groups: control,...
[ 2 ] - Effects of Saffron (Crocus sativus L.) Stigma Extract and its ActiveConstituent Crocin on Neuropathic Pain Responses in a Rat Model of Chronic Constriction Injury
This study was designed to investigate the therapeutic effects of saffron (Crocus Sativus L) and its main constituent crocin on neuropathic pain behavioral responses induced by chronic constriction injury (CCI) in rats. Adult male Wistar rats (200 to 250 g) were randomly assigned into 5 groups: Sham + saline, CCI + saline, CCI+ saffron (30 mg/kg), CCI +crocin (15 mg/kg) and CCI + crocin (30 mg/...

[ 4 ] - مهار تولید گلوکوکورتیکوئیدها و برداشتن غده فوق کلیوی مانع اثرات مثبت ورزش بر حافظه ترس و تعداد نرون‌های هیپوکمپ در موش سفید بزرگ آزمایشگاهی می شود
هدف: مطالعات جدید نشان می دهند که ورزش اثرات مفیدی بر فعالیت‌های شناختی و سلامت مغز دارد. از طرف دیگر گلوکوکورتیکوییدها نقش مهمی در یادگیری و حافظه هیجانی برای می کنند و فعالیت آنها در طی ورزش زیاد می‌شود. در مطالعه قبلی ما نشان دادیم که گلوکوکورتیکوییدها نقش مهمی در وساطت اثرات ورزش ارادی بر حافظه فضایی دارند. هدف مطالعه حاضر بررسی نقش گلوکوکورتیکوییدها در اثرات مثبت ورزش بر حافظه ترس در مدل ...
[ 5 ] - بررسی اثرات تزریق محیطی و داخل هیپوکمپی سیگلوهگزامید به عنوان مهار‌گر سنتز پروتئین بر بازتثبیت تأخیری حافظه احترازی غیر فعال در موش بزرگ آزمایشگاهی
سابقه و هدف: فعال‌سازی حافظه‌های تثبیت شده، موج دوم تحکیم حافظه موسوم به بازتثبیت حافظه را فعال می‌کند. اخیراً، فرایند تثبیت تاخیری حافظه نیز پیشنهاد شده است که حاکی از وجود یک دوره تاخیری تثبیت حافظه بعد از یادگیری است. این فرایند به تولید پروتیین در مغز، به‌ویژه در هیپوکمپ وابسته است. هدف این مطالعه بررسی وجود فرایند احتمالی بازتثبیت تاخیری وابسته بعد از فعال‌سازی یک حافظه تثبیت شده و و...
[ 6 ] - Protective Effects of Enriched Environment Against Transient Cerebral Ischemia-Induced Impairment of Passive Avoidance Memory and Long-Term Potentiation in Rats
Introduction: Enriched Environment (EE), a complex novel environment, has been demonstrated to improve synaptic plasticity in both injured and intact animals. The present study investigated the capacity of an early environmental intervention to normalize the impairment of passive avoidance memory and Long-Term Potentiation (LTP) induced by transient bilateral common carotid artery occlusion (2-...
[ 7 ] - Evaluation of the epidemiological pattern of COVID-19 applying basic reproduction number: An educational review article
After the onset of the COVID-19 outbreak in Wuhan, China, and its spread to other countries, confrontation with it as an international emergency in all countries was seriously on the agenda of governments. Our country was not immune to this outbreak. Effective measures to combat this new virus would be certainly based on a proper understanding of the epidemiological pattern and its evaluation i...
[ 8 ] - Role of Amygdala-Infralimbic Cortex Circuitry in Glucocorticoid-induced Facilitation of Auditory Fear Memory Extinction
Introduction: The basolateral amygdala (BLA) and infralimbic area (IL) of the medial prefrontal cortex (mPFC) are two interconnected brain structures that mediate both fear memory expression and extinction. Besides the well-known role of the BLA in the acquisition and expression of fear memory, projections from IL to BLA inhibit fear expression and have a critical role in fear extinction. Howev...
