purpose : to evaluate the retinal nerve fiber layer (rnfl) and central corneal thickness (cct) in patients with exfoliation syndrome (xfs) methods : in this comparative case series we measures rnfl thickness and cct 30 patients with xfs and 30 age and sex matched healthy subjects who met the inclusion criteria. results : average rnfl in xfs group were significantly thinner than controls (94.36±...

purpose : to evaluate the correlation of central corneal thickness (cct) with refractive error and keratometry in a group of patients eligible for laser keratorefractive surgery, which may serve as a bias in studies on intraocular pressure (iop) measurement methods : in a cross sectional observational study, the right eyes of 340 patients who underwent laser keratorefractive surgery during the ...

bioleaching of spent refinery processing catalysts using adapted indigenous strains ofacidithiobacillus ferrooxidans to recover ni and mo, and the separation of ni from bioleaching liquor usingiron magnetic nanoparticles were optimized in this study. bioleaching optimization was performed usingcentral composite design (ccd) method to optimize temperature (32 to 38oc), initial ph (1.5 to 2), par...

well exposed famennian, mainly carbonate rocks of the bahram formation in the vicinity of bagher abad village, central iran,yielded chondrichthyan teeth some sarcopterygii and actinopterygii teeth and fragments. three different genera were recognizedamong the chondrichthyan teeth represented by: phoebodus turnerae, ph. spp., deihim mansureae (m2, m3), stethacanthus sp..acanthodian and sarcopter...

upper devonian sediments of the kuh-e zard area northwest of zefreh, central iran, arecomposed mainly of brown and grey limestones with sandstone and shale intercalations. they contain tracefossils such as chondrites isp., diplocraterion parallelum, fustiglyphus annulatus, lockeia isp., phycodesisp., and taenidium barretti. these trace fossils indicate a shallow marine environment

conclusions considering that neuronal function highly depends on environmental conditions, any adverse alteration may affect the function and morphology of neurons. in this regard, our results showed the adverse effects of protein malnutrition on the morphology of the purkinje cells of cerebellum. results the low-protein group did not gain weight as much as control group (p < 0.05). the diamete...

central venous catheterization (cvc) is a commonly performed procedure for venous access. it is associated with several complications. we report a rare case of extra luminal entrapment of guide wire during cvc placement in right jugular vein. we report a case of 28 years old female patient presented in our emergency with history of entrapped guide wire in right side of neck during cvc. x-ray sh...

an abrupt global warming event has been recorded in many parts of the world in sediments of latest maastrichtian age between 65.45-65.10 ma. this warm event was documented here at a section near ziyarat-kola in central alborz based on analysis of planktonic foraminifera. an unusual abundance of normally large-size species such as globotruncana arca, globigerinelloides subcarinatus, pseudoguembe...
