WebWe develop and analyze a reaction-diffusion model to investigate the dynamics of the lifespan of a bystander signal emitted when cells are exposed to radiation. Experimental studies by Mothersill and Seymour 1997, using malignant epithelial cell lines, found that an emitted bystander signal can stil … Webcell contact transmission of bystander factors may be only part of the bystander mecha-nism. Bioelectric or bio magnetic fields may have a role to play. To test this further, cells were placed in a Magnetic Resonance Imaging (MRI) machine for 10min using a typical head scan protocol. This treatment also induced a bystander response. Apart from the

WebClassical radiation biology research has centred on nuclear DNA as the main target of radiation-induced damage. Over the past two decades, this has been challenged by a significant amount of scientific evidence clearly showing radiation-induced cell signalling effects to have important roles in mediating overall radiobiological response. WebSep 21, 2004 · The bystander response was based on the production of micronuclei (MN) (a measure of chromosomal damage) in the cell population. The abundance of MN increased when a single T98G cell in the population was exposed to a single 3 He 2+ ion, and the bystander response occurred in T98G cultures and in cocultures with human … highway city plans
