Gamma irradiation is routinely used for suppression of lymphocyte function in transfusion and transplantation procedures. In recent years, some investigators focused on the effects of ionizing radiation on special aspects of lymphocyte function and considered the possibility of its clinical application for treatment of some immunological disorders. In this study, we evaluated the effects of fiv...

OBJECTIVES The aim of the study was to determine if isosorbide-5-mononitrate (IS-5-MN) 120 mg, taken once daily for 7 days, is associated with evidence of endothelial dysfunction and whether this effect is determined by increased free radical production. BACKGROUND Tolerance to nitroglycerin is associated with increased free radical production and abnormal endothelial function. To date, no da...

in this report, we present a facile approach for the synthesis of luminescent cds and cds:mn+2 nanocrystals by reaction of cdso4 and na2s2o3 in the presence of thioglycerol (c3h8o2s) as capping agent. the influence of various experimental variables including, ph values and percentage of dopant, on the growth rate and optical properties of the obtained cds nanocrystals has been systematically in...

conclusions according to our study, phototherapy should not be used as prophylactic therapy for all vlbw infants, but rather it should be individualized in order to maintain low bilirubin levels. results the mean bilirubin level on the first day in both groups exhibited no significant difference. the peak serum bilirubin was 7.7 ± 1.4 and 8.5 ± 2.1 mg/dl in the prophylactic and therapeutic grou...

OBJECTIVES Epidemiologic studies on physical exposure during computer use have mainly focused on average exposure duration. In this study, we aimed to relate periods of high peak exposure during computer use with the occurrence of neck-shoulder (NS) and arm-wrist-hand (AWH) symptoms. METHODS A prospective cohort study among 1951 office workers was carried out for two y...

BACKGROUND Tasks involved in traditional charcoal production expose workers to various levels of charcoal dust and wood smoke. This study aimed to identify specific tasks influencing lung function and respiratory symptoms. METHODS Interviews, direct observation, and task/symptom checklists were used to collect data from 50 charcoal-production workers on 3 nonwork days followed by 11 workdays....
