The frequency-dose relation of x-ray-induced y-suppressed lethals in Drosophila.
E A R L Y in radiation genetic investigations it was reported that X-ray-induced sex-linked recessive lethals were not homogeneous in composition. Instead they included: ( 1 ) apparent intragenic changes without observable cytological abnormalities (point mutations) ; (2) deficiencies; and (3) changes associated with and, for the most part, inseparable from chromosome rearrangements (OLIVER 193...
متن کاملاثر محافظتی سیتوکین SCF در مهار آپوپتوز ناشی از اشعه X در سلول های HL60
Background and purpose : Âpoptosis or programmed cell death is a process of cell suicide. Ïonizing radiation is one of the stimuli for apoptosis, acting through DNÂ damage. Ïn the present study, effects of X-rays induced apoptosis in HL60 cells, as well as the protective effects of Stem Çell Factor (SÇF) in inhibiting X-ray induced apoptosis have been evaluated. Materials and methods : HL6...

متن کاملBiological Dose Assessment by Chemical Induction of Premature Chromosome Condensation
Dose assessment of radiation victims is a key element in medical management of radiation accidents. At high radiation doses (> 6 Gy), dicentric assay lose its efficiency and premature chromosome condensation (PCC) assay was proposed to overcome the restrictions of dicentric assay. It was shown that PCC ring is more suitable and simpler than dicentric for biodosimetry in high radiation doses. In...
متن کاملA proton induced X-ray emission (PIXE) analysis of concentration of trace elements in varicose veins
Background: Proton induced X-ray emission (PIXE) has been applied as reliable and improved techniques in this study to compare concentration of various trace elements in normal and abnormal varicose veins. Materials and Methods: Five samples from normal veins and 13 samples from varicose veins bombarded by 2.0 MeV energy proton beams produced by a Van de Graff accelerator in vacuum. T...
