متن کاملRadiation - perturbed signalling and systems radiation biology
In deep space astronauts are usually exposed to doses of ~ 1 mSv/day of charged particles, including HZE. Due to the exposure to GCR (e.g. during a mission to Mars), each cell nucleus of an astronaut would be traversed by a proton or by a secondary electron every few days, but only by an HZE ion every few months [1]. For this reason, besides the clustered properties of the incoming radiation on...
متن کاملIntegrative radiation systems biology
Maximisation of the ratio of normal tissue preservation and tumour cell reduction is the main concept of radiotherapy alone or combined with chemo-, immuno- or biologically targeted therapy. The foremost parameter influencing this ratio is radiation sensitivity and its modulation towards a more efficient killing of tumour cells and a better preservation of normal tissue at the same time is the ...
