Radiation interaction with DNA
We developed a model to describe the radiation-DNA interaction in water solution. The model is based on some important aspects of the Bethe Theory for the ionizing process, and on the assumption that the direct interaction between the incident particle and the DNA molecule is negligible in comparison with the indirect effect. This assumption can always be true under controlled conditions. The r...
متن کاملThe Mechanisms of Radiation-Induced Bystander Effect
The radiation-induced bystander effect is the phenomenon which non-irradiated cells exhibit effects along with their different levels as a result of signals received from nearby irradiated cells. Responses of non-irradiated cells may include changes in process of translation, gene expression, cell proliferation, apoptosis and cells death. These changes are confirmed by results of some In-Vivo s...
متن کاملRadiation Protection with Nanoparticles
At the onset of radiation exposure, free radicals are formed through ionizing reactions that are then capable of destroying normal tissues. While cells release a level of protective molecules, such as glutathione and metallothionine, they are not capable of blocking all damage, thus resulting in the death of normal tissues and therefore, we must continue to develop strategies to protect normal ...
متن کاملGenomic Instability and Bystander Effect – Implications for Radiation Protection
The main results of the EC project ‘Genomic instability and radiation-induced cancer’ (RADINSTAB) are reviewed and the potential implications of genomic instability and bystander effect for risk assessment and radiation protection discussed. A basic paradigm in radiobiology is that, after exposure to ionising radiation, the deposition of energy in the cell nucleus and the resulting damage to DN...
متن کاملGeneral tissue reactions and implications for radiation protection.
Non-cancer effects and risks at low doses from ionising radiation are controversial topics within the field of radiation protection. These issues are discussed in International Commission on Radiological Protection (ICRP) Publication 118, 'ICRP statement on tissue reactions'. Both non-cancer effects and risks are expected to become increasingly important to the system of radiation protection. B...
