Background and purpose: In the past, olibanum was used as an incense and perfume and a remedy for treating various diseases. Now, it is confirmed that olibanum improves memory and has a role in treatment and prevention of Alzheimer disease. CaMKIIα gene is known as molecular memory because of its role in cellular processes associated with memory. The aim of this research was to study the effect...
Introduction: Exposure to ethanol as a neurotratogen in the developmental period has destructive effects on the central nervous system and causes neurological disorders in adulthood. These disorders are associated with apoptosis in areas of the brain such as the hippocampus, by activating the oxidative-inflammatory cascade and high levels of nerve degeneration. Simvastatin, used as a drug to tr...
Introduction: Aging is the major risk factor for neurodegenerative diseases and oxidative stress is involved in the pathophysiology of these diseases. Oxidative stress can induce neuronal damages and modulate intracellular signaling, ultimately leading to neuronal death by apoptosis or necrosis. Methods: In this study, we investigated the possible antioxidant and neuroprotective properties o...
The Ef fect of Microwave Radiation Emitted by Mobile Phones on Human Short Term Memory S.M.J. Mortazavi [1] , M. Nazer [2] , A.R. Sayyadi 2 , H. Karimi [3] Received: 15/08/07 Sent for Revision: 26/10/08 Received Revised Manuscript: 26/11/08 Accepted: 11/01/09 Background and Objectives : The widespread use of cell phones has made the researchers focus on its health effects. However...
people with alzheimer disease (ad) have decreases in brain cell function that may increase their risks as drivers. the changes in brain cells affect memory (at first, short-term memory and then much later, long-term memory) and other thinking functions. in addition, people with early ad, though often very functional in many areas of life, may not be as competent behind the wheel of a car as tho...
recently, the hypothesis in which memory and information would be stored as magnetic forms in astrocytes is expanding and neuromagnetic interactions between neurons and neighboring astrocytes in neocortex have potential to be the basis of memory formation. it has been proposed that all sorts of information may be maintained in form of neuronal activity-associated magnetic fields (naamfs) and th...
introduction: previous studies have demonstrated that the &beta-adrenergic; receptor antagonist propranolol impairs fear memory reconsolidation in experimental animals. there are experimental parameters such as the age and the strength of memory that can interact with pharmacological manipulations of memory reconsolidation. in this study, we investigated the ability of the age and the strength ...
One of the most nervous system evolution are memory and learning in humans. Learning is a skill that enhances synaptic activity in the hippocampus of prefrontal cortex. In fact, basic passive learning is communication between the conditioned and Unconditioned stimulation. Passive learning involves three steps: habit, education and remember. According to the results of investigations, the hippoc...
امروزه با توسعه روز افزون تکنولوژی mems و کاربردهای گسترده آن در مهندسی پزشکی می توان قطعاتی را طراحی نمود که قابل کاشت (implantable ) در داخل بدن باشد. اندازه گیری مقدار قند خون یکی از زمینه هایی می باشد که با توسعه تکنولوژی memsمورد توجه بوده است. در بیماران دیابتی نوع دوم، میزان قند خون بالا می باشد و از آنجایی که با افزایش قند خون احتمال بیهوشی نیز بالا می رود، لذا اندازه گیری قند خون بصورت...
