[ 1 ] - The effect of melatonin on Superoxide dismutase and Glutathione peroxidase activity, and Malondialdehyde levels in the targeted and the non-targeted lung and heart tissues after irradiation in xenograft mice colon cancer
Introduction: Introduction: Radiation causes damage to irradiated tissues and also tissues that do not receive direct irradiation through a phenomenon called bystander effects. Melatonin as a potent antioxidant and anti-inflammatory agent is known for protection of normal tissues against ionizing irradiation. In addition, some studies have suggested that Melatonin may have some...
[ 2 ] - Adsorption of Radioactive Materials by Green Microalgae Dunaliella Salina from Aqueous Solution
Introduction: Nuclear accidents release large quantities of radioactive materials into the environment. Iodine-131 and cesium-137 are two radionuclides released during nuclear accident, which can pose the greatest cancer risks. These radionuclides can be moved to other areas through rain and wind. The aim of this study was to develop efficient and economical biological...
[ 3 ] - Radiation-induced Non-targeted Effect and Carcinogenesis; Implications in Clinical Radiotherapy
Bystander or non-targeted effect is known to be an interesting phenomenon in radiobiology. The genetic consequences of bystander effect on non-irradiated cells have shown that this phenomenon can be considered as one of the most important factors involved in secondary cancer after exposure to ionizing radiation. Every year, millions of people around the world undergo radiotherapy in order to cu...
