To assess the potential use of the comet assay in radiation biodosimetry, the DNA repair kinetics should be considered in the dose-response curve. Therefore, we combined the dose-effect curve and the Cited by: McKeown SR, Robson T, Price ME, Ho ET, Hirst DG, McKelvey-Martin VJ.

Singh vs. Olive: Two Variations of the Comet Assay. The Motorola project was billed as a test of the Lai-Singh experiment, yet the contract stipulated that Roti Roti would not use Singh’s. At low radiation doses, ____ are considered to be the cellular radiation damage that results in the stochastic radiation effects observed at the whole-body level.

R Free Response Question 6 Comet assay to detect double-stranded breaks in DNA A comet assay is a technique used to determine the amount of double-strand breaks in DNA (DNA damage) in cells. File Size: KB. For some agents (e.g., ultraviolet-C radiation and N-methyl-N'-nitro-N-nitrosoguanidine), damage measured using the comet assay can be a result of incision at sites of base damage Cited by: Start studying Chapter Stochastic Effects of Radiation.
Learn vocabulary, terms, and more with flashcards, games, and other study tools. The calibration curves are not all in agreement. While it has been accepted for some years that the maximum dose detected with the assay is ∼10 Gy equivalents, some published calibration curves (e.g.
Figure 1f) have a more gradual dose–response discrepancies might arise from subtle variations in protocols, or from differences in yield of breaks arising from the use Cited by: The mechanisms of response to radiation exposure are conserved in plants and animals.
The DNA damage response (DDR) pathways are the predominant molecular pathways activated upon exposure Cited by: 7. comet assay we analysed the level of DNA damage and repair in isolated gδ T-lymphocytes, pan T-lymphocytes and in total PBMC exposed in vitro to gamma radiation.
We found no difference in the Cited by: 2. Introduction. The single-cell gel electrophoresis assay or comet assay is a technique used in measuring DNA damage and repair at a cellular level (1,2).It was first developed over 20 years ago by Ostling and Johanson ().Versatility and speed coupled with simplicity and economy have seen the number of people who use Cited by: 9.

gamma spectrum using HPGe-detector. From the PACE reaction cross section and the observed gamma spectrum it is seen that there is a possibility of (2p, 2n), (1p, 3n) and (D) channel reactions.
The observed gamma spectrum is also very much useful for the radiati. In the case of genetic toxicology testing, it has been recommended to use image analysis - see Hartmann et al., Mutagene). As an alternative, you can use the visual scoring approach. The internal radiation therapy, also called brachytherapy, is released from gamma-radiation sources such as radioactive isotopes like 60 Co and Cs, which are placed within the patient's body.
This type of Cited by: The effects of dose-rate and its implications on radiation biodosimetry methods are not well studied in the context of large-scale radiological scenarios.
