Genetic Risk Factors for Radiation Vasculopathy.
Purpose The purpose of this study was to perform a genome-wide scan for polymorphisms associated with risk of vision loss from radiation complications in patients treated with proton beam irradiation for choroidal melanoma. Methods We identified a cohort of 126 patients at high risk of radiation complications due to tumor location within 2 disc diameters of the optic nerve and/or fovea who pr...
متن کاملGreater risk from radiation?
adiation can harm cells even if they don't take a direct hit, according to a new study. Injured cells apparently pass on damage to neighboring cells through gap junctions. The report has raised a ruckus because it suggests that current safety standards may underestimate the hazards from low-level radiation exposure Although some scientists suspected that radiation damage might spread from cell ...
متن کاملThe genetic risk in mice from radiation: an estimate of the mutation induction rate per genome.
Restriction Landmark Genome Scanning (RLGS) is a method that uses end-labeled (32)P NotI sites that are mostly associated with coding genes to visualizes thousands of DNA fragments as spots in two-dimensional autoradiograms. This approach allows direct detection of autosomal deletions as spots with half normal intensity. The method was applied to mouse offspring derived from spermatogonia expos...
متن کاملThe cancer risk from low-level radiation.
INTRODUCTION. It is commonly stated that " any radiation dose, no matter how small, can cause cancer ". The basis for that statement is the linear-no threshold theory (LNT) of radiation carcinogenesis. According to LNT, if 1 Gy (100 rads) of exposure gives a cancer risk R, the risk from 0.01 Gy (1 rad) of exposure is R/100, the risk from 0.00001 Gy (1 millirad) is R/ 100,000, and so on. Thus th...
متن کاملRadiation risk to children from computed tomography.
Imaging studies that use ionizing radiation are an essential tool for the evaluation of many disorders of childhood. Ionizing radiation is used in radiography, fluoroscopy, angiography, and computed tomography scanning. Computed tomography is of particular interest because of its relatively high radiation dose and wide use. Consensus statements on radiation risk suggest that it is reasonable to...
