background: lead, an example of heavy metals, has, for decades, being known for its adverse effects on various body organs and systems such that their functions are compromised. objective: in the present study, the ability of lycopersicum esculentum on decrease toxic effects of lead acetate on plasma superoxide dismutase, catalase and malondialdehyde in rat. lead to adversely affect the liver t...

background: the problem of the environmental pollution by nanoparticles, which have recently entered the cycle of industries process in iran, is very important and can be prevented with applying the proper management approaches. one of the most practical compounds is zno nanoparticle. in the present study  the (lethal concentration-50) lc50 24hr and 48hr of zno nanoparticles exposed-to reactive...

objectives: postural control deficit is one of the most important problems in children with spastic cerebral palsy (cp). the purpose of this paper is to review the reactive postural control in spastic children with cp. methods: researches on development of reactive postural control in typically developing (td) children and children with cerebral palsy (cp) were analyzed. results: the results of...

In a de-regulated open access environment, reactive power is one of the ancillary services which must be provided by an Independent System Operator (ISO). In this paper, a new algorithm is proposed in which reactive power resources are initially so tuned that optimum security in terms of voltage profile and voltage stability are achieved while at the same time, the system losses are minimized. ...

background: flat urothelial lesions comprise a spectrum of morphologic changes ranging from reactive atypia to carcinoma in situ (cis). urothelial dysplasia and cis are associated with the recurrence and progression of urothelial carcinoma. distinguishing cis and dysplasia from reactive atypia based on histolopathogical features alone is often difficult. using different immunohistochemical mark...

bokbunja seed wastes from a wine manufacturing industry were used to prepare carbon for the purpose of using it as an adsorbent for the removal of reactive blue 4 from aqueous solutions. a part of prepared carbon was treated with n-hexane to remove the seed oil present in large amounts in bokbunja seeds. it was found that the hexane treated carbon was more efficient in removing the dye from aqu...

background; conventional chemical coagulation is considered as the old method to color and cod removal in textile effluent. electrocoagulation (ec) process is a robust method to achieve maximum removal. methods; this work was designed to compare the result of operational parameters including optimum ph and coagulant concentration for chemical coagulation with ferric chloride and alum. also, the...

recent studies show that, inflammation plays an important role in the initiation and progression of atherosclerosis and in the pathogenesis of acute cardiovascular events. there is a possible association between ventricular dysfunction following acute myocardial infarction and high sensitivity c-reactive protein (hs-crp) and uric acid. in this study we assessed the relationship between hs-crp a...
