Protective effect of ferulic acid on ionizing radiation induced damage in bovine serum albumin
Background: Ionizing radiation causes deleterious effects on living system mainly due to oxidative damages of macromolecules and protein is the major target due to its abundance. The aim of this study was to investigate the effects of ionizing radiation induced changes in the molecular properties of bovine serum albumin (BSA) its secondary and tertiary structures, degradation, cross linking and...
متن کاملRepair of ionizing radiation induced DNA damage in human lymphocytes.
Phytohemagglutinin stimulated human lymphocytes exhibit a 20 fold increase in DNA repair synthesis following ionizing radiation damage compared to the level of repair in unstimulated cells. The peak of repair synthesis coincides with that for DNA replication. Stimulated lymphocytes provide a relatively simple assay for ionizing radiation repair defects.
متن کاملEffect of sodium azide on radiation damage and photoreactivation.
During investigations on the role of bacterial pigments in ultraviolet irradiation damage and in photoreactivation, several agents were tested as suppressors of pigmentation effects. Chromobacterium violaceum is extremely radiosensitive in that it shows very high inactivation by ultraviolet and also high photorecovery with white light. Sodium azide depresses both of these effects significantly....
متن کاملIonizing Radiation Induced Radicals
When ionizing radiation passes through a material it imparts some of its energy to that material. The imparted energy may be high enough to cause a break in bonds inside the molecules or between molecules or both, in such cases, free radicals are created. The type, lifetime, extent, fate and origin of those free radicals may differ according to several factors; most of them are beyond the subje...
متن کاملEffect of Exposure to Ionizing Radiation on Biomarker of Oxidative Damage of DNA
Introduction: one of the most important complications of exposure to ionizing radiation is emergence of cancer tumors, which happens as a result of oxidative DNA. Therefore, the present study was conducted, aimed to measuring 8-DIHYDROxy- 2’- DEOXYGUANOSINE (8-OHdG) level in radiographers’ urine as oxidative damage biomarker, as well as comparing this biomarker with cumulative effective doses....
