Visualization of Gamma H2AX Foci

Lead Institution
NASA Ames Research Center
Principal Investigator
Marianne Sowa
Project type
Exploratory Research
Genomically unstable cells have been demonstrated to release a "factor" into the medium which when transferred to stable cells results in 100% cell death. First demonstrated by Nagar and…

Cellular responses to ionizing radiation as examined by FTIR.

Lead Institution
Middle East Technical University
Principal Investigator
Feride Severcan
Project type
Exploratory Research
Currently, the standards for human exposure to ionizing radiation are set by extrapolating data obtained in the high-dose regime to the low-dose regime where the biological responses are below…

electron induced low-dose hypersensetivity

Lead Institution
Wayne State University
Principal Investigator
Michael Joiner
Project type
Exploratory Research
Following very low acute radiation exposures, an increase in radiosensitivity has been detected at doses below 1 Gy in a number of cell lines in vitro. This phenomenon is termed ?low-dose hyper…
