The present study concentrates on the synthesis of Au nanoparticles (AuNPs) using aqueous solution of Polyvinylpyrrolidone (PVP) and tetrachloroaurate by different methods as thermal, sonochemical and electrochemical reduction. The PVP has been used as a reducing agent and acts as a stabilizer for Au nano particles that obtained as principal product. In all synthesis procedures, the active radi...

Until recently, corneal biomechanical properties could not be measured in vivo. The ocular response analyzer is a new, noninvasive device that analyses corneal biomechanical properties simply and rapidly. The ORA allows cornea compensated IOP measurements and can estimate corneal hysteresis (CH) and corneal resistance factor (CRF). It is designed to improve the accuracy of IOP measurement by us...

Background: Intrauterine infections (TORCH) lead to the involvement of various organs of the body of the fetus, including the eye. The aim of this study was to determine the frequency and clinical response of eye lesions to specific drugs, in infants with confirmed TORCH induced ocular lesions. Methods: This historical cohort study from 2011 to 2017, had done in Pediatrics and Ophthalmology De...

purpose : to study the age and gender specific history of ocular trauma in the population of tehran methods : using a stratified cluster sampling approach, 6,497 residents of tehran were selected. participants were transferred to an eye clinic to have complete eye examinations. during the interview, participants were asked about any history of ocular trauma, and any treatment or hospitalization...

A transient iridocyclitis is produced in rabbits by the intravenous injection of bacterial endotoxin. A major feature of this response is an altered vascular permeability which can be measured by the ocular accumulation of circulating 125I-labeled albumin. The present study was made to determine the effects of inhibitors of prostaglandin synthesis of the ocular response to an E. coli 055:B5 end...

est (rst) is the most commonly used electrodiagnostic test to asses the defect of neuromuscular transmission, which is reported to be positive in the diffuse and restricted ocular forms 60-95% and 14-50%, respectively. in a cross-sectional study, to determine the efficacy of repetitive stimulation test in myasthenia gravis, we evaluated the results in 30 cases who were hospitalized in imam khom...
