1. Cellular effects of ionizing radiation : Relevant for understanding cancer risk after medical and environmental radiation exposures
Abstract : Radiation-induced cancers are stochastic and delayed effects of exposure to ionizing radiation. The dose-response relationship for radiation-induced cancers at both low dose/low dose rates and high doses (doses encountered during radiotherapy) remains unclear. READ MORE

2. The microdosimetric variance-covariance method used for beam quality characterization in radiation protection and radiation therapy
Abstract : Radiation quality is described by the RBE (relative biological effectiveness) that varies with the ionizing ability of the radiation. Microdosimetric quantities describe distributions of energy imparted to small volumes and can be related to RBE. READ MORE

3. Role of MTH1 and MYH proteins in genotoxic effects of radiation
Abstract : Humans are constantly exposed to different types of radiations. It has been suggested that low dose and low dose rate of γ-radiation as well as ultra violet A (UVA) induce oxidative stress in cells that may promote mutations. READ MORE

4. Methods for the analysis and characterization of brain morphology from MRI images
Abstract : Brain magnetic resonance imaging (MRI) is an imaging modality that produces detailed images of the brain without using any ionizing radiation. From a structural MRI scan, it is possible to extract morphological properties of different brain regions, such as their volume and shape. READ MORE

5. Optimizing experimental radioimmunotherapy : investigating the different mechanisms behind radiation induced cell deaths
Abstract : Background. Radiation therapy is an important treatment regimen for malignant disease. Radiation therapy uses ionizing radiation to induce DNA damage in tumor cells in order to kill them. READ MORE
