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 ...

abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...

Introduction: The exposure of human brain to electromagnetic waves can show adverse effects on brain functions. Electromagnetic waves effects on adult and child head have been investigated and compared In the present study. Methods and Materials: A simple spherical model consisted of six layers is considered to simulate the behavior of human brain. HFSS (High Frequency Structure Simulator) ha...

rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...

Background and purpose: Overproduction of free radicals after brain ischemia exacerbates brain infarction and edema specifically during early reperfusion. The scavenging property of water-soluble fullerene derivatives is proven, so, the aim of this study was to evaluate the effects of fullerenol nanoparticles on brain infarction and edema, especially oxidative damages during reperfusion in an e...
