Enhancement of Bio-Protective Functions by Low Dose/Dose-Rate Radiation [PDF]
Dose-Response, 2006 Effects of low-dose-rate gamma-irradiation on the process of tumorigenesis were investigated in mice treated with a carcinogenic agent or irradiated with high dose X-rays at a high dose rate.

Application of the Linear-Quadratic model to targeted radionuclide therapy [PDF]
, 2011 PhDThe principal aim of this work was to test the hypothesis that the Linear-Quadratic (LQ) model of cell survival, developed for external beam radiotherapy (EBRT), could be extended to targeted radionuclide therapy (TRT) in order to predict dose ...

The Emerging Roles of Exosomes as EMT Regulators in Cancer
Cells, 2020 Epithelial–mesenchymal transition (EMT) causes epithelial cells to lose their polarity and adhesion property, and endows them with migratory and invasive properties to enable them to become mesenchymal stem cells.

Mutagenicity of radiations at low doses [PDF]
Hereditas, 2009 The mutagenic effectiveness of low-LET radiations was studied in E. coli Sd-4, with emphasis on low doses. At the lowest dose tested, 0.75 Gy, the mutation frequency per unit dose was found to be highest. It then dropped to an approximately linear curve in the range 5–50 Gy and became again higher at still higher doses.

Organ-Specific Effects of Low Dose Radiation Exposure: A Comprehensive Review
Frontiers in Genetics, 2020 Ionizing radiation (IR) is a high-energy radiation whose biological effects depend on the irradiation doses. Low-dose radiation (LDR) is delivered during medical diagnoses or by an exposure to radioactive elements and has been linked to the occurrence of

Low dose ionising radiation produces too few ROS to directly affect antioxidant concentrations in cells [PDF]
, 2012 It has been hypothesized that radiation-induced oxidative stress is the mechanism for a wide range of negative impacts on biota living in radioactively contaminated areas around Chernobyl.

Cancer Risk of Low Dose Ionizing Radiation
Frontiers in Physics, 2020 The radiation exposure of individuals has been on the rise due to an increased amount of radiation use, e.g., in medicine for diagnostic imaging and treatment procedures, industrial applications including military defense activities and nuclear power ...
