Proton irradiation of DNA nucleosides in the gas phase.
The four DNA nucleosides guanosine, adenosine, cytidine and thymidine have been produced in the gas phase by a laser thermal desorption source, and irradiated by a beam of protons with 5 keV kinetic energy. The molecular ions as well as energetic neutrals formed have been analyzed by mass spectrometry in order to shed light on the ionization and fragmentation processes triggered by proton colli...
متن کاملProton beam irradiation inhibits the migration of melanoma cells
PURPOSE In recent years experimental data have indicated that low-energy proton beam radiation might induce a difference in cellular migration in comparison to photons. We therefore set out to compare the effect of proton beam irradiation and X-rays on the survival and long-term migratory properties of two cell lines: uveal melanoma Mel270 and skin melanoma BLM. MATERIALS AND METHODS Cells tr...

' The kinetics of recuperation following initial doses of 470 rads of 56 Mev protons and 350 rads of Co" 7 radiation were investigated by means of the paired-dose method. By using semilog plots, recovery half-times of 4.85 ± .85 days and 2.02 ± .45 day» were found after initial doses of the protons and Co' 7 radiation, respectively.
متن کاملDose for Proton Irradiation
With the increase in the amount of time spent EVA that is necessary to complete the construction and subsequent maintenance of ISS, it will become increasingly important for ground support personnel to accurately characterize the radiation exposures incurred by EVA crewmembers. Since exposure measurements cannot be taken within the organs of interest, it is necessary to estimate these exposures...
متن کاملEvaluation of the effect of low-level laser irradiation on viability and ROS production in human hair follicle stem cells
Background: Low-level lasers are used for various medical applications including wound healing and hair loss treatment. Cell Therapy using skin stem cells could be a novel approach to hair transplantation. However, there is no study on the effect of low-level laser on the hair follicle stem cells. So, in this study, we investigated the effect of low level laser irradiation on viability and ROS ...
