Background: Lead-based radiation shields are widely used in radiology departments to protect both workers and patients from any unnecessary exposure to ionizing radiation. Recently there has been a great deal of concern expressed about the toxicity of lead. Human lead toxicity is well documented. In that light, production of environmentally-friendly lead-free radiation shields with less weight ...
Introduction: Parkinson's disease (PD) is among the most common neurodegenerative disorders. Given the powerful antioxidant effects of the saffron extract on the removal of free radicals, this study aimed to investigate the protective effects of the saffron extract on reducing oxidative stress in a rat model of Parkinson's disease pretreated with saffron. Materials & Methods: In this experim...
Background and Objective: Diazinon is one of the most widely used organophosphates (OPs) in agriculture. Toxic effects of diazinon are due to the inhibition of acetylcolinesterase, an enzyme needed for proper nervous system function. Investigates show that different classes of OPs may induce the production of free radicals and in cause disturbance in body antioxidant systems. The purpose of t...
abstract. let (r,p) be a noetherian unique factorization do-main (ufd) and m be a finitely generated r-module. let i(m)be the first nonzero fitting ideal of m and the order of m, denotedord_r(m), be the largest integer n such that i(m) ⊆ p^n. in thispaper, we show that if m is a module of order one, then either mis isomorphic with direct sum of a free module and a cyclic moduleor m is isomorphi...
free surface sloshing of liquid in a rectangular tank induced by lateral excitation has been studied numericallyand experimentally in this paper. the numerical simulation is carried out based on the volume of fluid (vof) method that provides free surface extraction in such problem. a tank with transparent walls is used to free surface tracking in experimental study while the movement amplitude ...
introduction: leptin is a hormone resulting from the obesity gene which could be important in the pathogenesis of the insulin. only limited data concerning the interaction of insulin, glucose tolerance and free leptin are available and no data exist on the potential influence of free vs. bound circulating leptin. we, therefore, studied percentage of free to total leptin in diabetic patients. ma...
here, we report analysis of in vitro and in vivo drug release from an in situ formulation consisting of triamcinolone acetonide (tr) and poly(d,l-lactide-co-glycolide) (plga) and the additives glycofurol and hydroxyapatite nanoparticles (ha). we found that these additives enhanced drug release rate. we used the taguchi method to predict optimum formulation variables to minimise the initial burs...
apoptosis, a physiologic mechanism to eliminate unwanted cells, is also induced by ionizing irradiation, through production of free radicals. it has been demonstrated that antioxidants such as vitamin e are able to protect cells from damage caused by free radicals. taken together we found it reasonable to make an attempt to evaluate the protective effect of vitamin e against apoptosis. the irra...
the present article studies one of the new methods of story narration which reviews the constant stream of thoughts and feelings inside the minds of the characters of the story. one of the basic objectives of applying this technique is having freedom in the regular elements of theme and plot. instead of codes the story is based on tangible and touchable realities so that the reader will be able...
