- Low-dose Radiation-Induced Protective Process and Implications for Risk Assessment, Cancer Prevention, and Cancer Therapy. Scott, B. R. // Dose-Response;2007, Vol. 5 Issue 2, p131
A low-dose protective apoptosis-mediated (PAM) process is discussed that appears to be turned on by low-dose gamma and X rays but not by low-dose alpha radiation. PAM is a bystander effect that involves cross-talk between genomically compromised [e.g., mutants, neoplastically transformed,...
- Radiation-Induced Neoplastic Transformation in Vitro, Hormesis and Risk Assessment. Redpath, J. Leslie; Elmore, Eugene // Dose-Response;2007, Vol. 5 Issue 2, p123
Dose-response curves for various low-LET radiation sources have consistently been demonstrated to be J-shaped for the cancer-relevant endpoint of neoplastic transformation in vitro. Most of these studies have been performed where the radiation has been delivered at intermediate to high...
- TNF-Î± and Microglial Hormetic Involvement in Neurological Health & Migraine. Kraig, Richard P.; Mitchell, Heidi M.; Christie-Pope, Barbara; Kunkler, Phillip E.; White, David M.; Tang, Ya-Ping; Langan, George // Dose-Response;2010, Vol. 8 Issue 4, p389
Environmental enrichment, i.e., increased intellectual, social, and physical activity makes brain more resilient to subsequent neurological disease. The mechanisms for this effect remain incompletely defined, but evidence shows tumor necrosis factor-alpha (TNF-Î±) is involved. TNF-Î±, at...
- Association Between Local External Gamma Rays and Frequency of Cancer in Babol-Iran. Monfared, Ali Shabestani; Hajian, Karimollah; Hosseini, Reza; Nasir, Akbar // Dose-Response;2010, Vol. 8 Issue 3, p368
Introduction: The effect of natural background radiation on Cancer is still challenging. The investigation of association between external gamma rays and Cancer was the main goal of study. Materials & Methods: External Gamma rays were measured using a radiation survey meter in 184 urban and...
- Radio-Adaptive Response to Environmental Exposures at Chernobyl. Rodgers, Brenda E.; Holmes, Kristen M. // Dose-Response;2008, Vol. 6 Issue 2, p209
The genetic consequences resulting from environmental exposure to ionizing radiation have a significant impact on both radiation regulatory policies and the comprehension of the human health risks associated with radiation exposure. The primary objectives of the study were to assess 1)...
- Preface. Cuttler, Jerry; Mitchel, Ron // Dose-Response;2006, Vol. 4 Issue 4, p255
A preface for the October 2006 issue of "Dose-Response" is presented.
- External occupational exposures in some NORM industries located at the South-West of Spain. Bolivar, J. P.; García-Tenorio, R. // AIP Conference Proceedings;8/7/2008, Vol. 1034 Issue 1, p364
Detailed mappings of the external exposures which can be received by the workers in two NORM industrial factories located at the South-West of Spain have been performed: one devoted to the production of phosphoric acid, and the other devoted to the production of titanium dioxide pigments. In...
- Nonlinearity of Radiation Health Effects. Pollycove, Myron; Calabrese, Edward J. // Environmental Health Perspectives Supplements;Feb98 Supplement 1, Vol. 106, p363
Presents a study in which observations of fundamental biologic cellular functions contradict the theoretical presumption based on biophysical concepts about the health consequences of radiation exposure and exclude a linear nonthreshold hypothesis dose-response relationship.
- Radiation Dose in the Selection of131 I or Surgical Treatment for Toxic Thyroid Adenoma. Gorma, Colum A.; Robertson, James S. // Annals of Internal Medicine;Jul78, Vol. 89 Issue 1, p85
Examines radiation dose in the selection of surgical treatment for toxic thyroid adenoma. Procedure used for computing the absorbed radiation dose in and near the thyroid nodule; Dose-effect modifying factors; Effects of dose-rate.
