brain injury has a multiple pathophysiology for which there is no definite treatment. in this regard, tissue engineering is one of the probable strategies for repair of damaged tissue. but creating a proper model for testing the engineered products faced some difficulties, specially, when we want to evaluate the effects of a product on the volume of injury. the current brain injury methods coul...
Brain's waves are produced by spontaneous activity of neurons. These waves are changed by neurotransmitters in the central nervous system (CNS). Concentration of these neurotransmitters can be changed by various drugs and total power of brain waves also increase or decrease by these drugs. In this research effect of Quinpirol and Sulpiride on the brain waves was investigated. Male wistar rats (...
Introduction: Despite the importance of specialized manpower in leading a country's economy, statistics show the departure of a large number of thinkers in various fields of science who for some reason prefer to live in developed countries to stay in their own country. In fact, brain drain represents the flow of human capital in which skills are transferred. Therefore, in this study, we will ex...
Background and Aim: Stroke is one of the most important factors of mortality and disability in the world. Free radicals are produced following ischemic stroke and they play a central role in breaking the blood-brain barrier and causing brain edema formation. The aim of the current study was to evaluate the effect of hydro- alcoholic extract of Origanum vulgare on brain edema and neurologic ...
Background. Teachers including university professors insist on keeping up to date with the updating of students' information and developing their scientific potentials, through use of diverse teaching strategies. Objectives. Identifying on the brain dominance and the hypocritical personality for students, knowledge effect SWOT and Kaizen strategy in the brain dominance and the hypocritical per...
recently, economists have attention to the brain drain as emigration of skilled and educated labor force from developing countries. in this case, we are dealing with one main question is: how brain drain can affect the human capital of source countries? based on existing theories, brain drain can affect the economy of source countries in different ways such as; direct reduction of human capital...
Pervious studies have shown that pentoxifylline (PTX) has beneficial effects in reduction of stroke and brain trauma injuries in experimental animals. However, there is very little and controversial information about the effect of PTX on brain edema in cerebral ischemia. Therefore, the aim of this study was to determine the effects of different doses of PTX on brain edema and neurological m...
objective(s) the brief interruption of cerebral blood flow causes permanent brain damage and behavioral dysfunction. the hippocampus is highly vulnerable to ischemic insults, particularly the ca1 pyramidal cell layer. there is no effective pharmacological strategy for improving brain tissue damage induced by cerebral ischemia. previous studies reported that pentoxifylline (ptx) has a neuroprote...
introduction: one of the main mechanisms by which diabetic complications occur is an alteration of the structure and function of proteins due to hyperglycemia. aspirin (asa) affects cellular pathways through different mechanisms, including glycation inhibition and antioxidant activity. the aim of the present study, as a follow up to our previous one, is to investigate the effect of long-term, h...
