DNA methylation changes following DNA damage in prostate cancer cells

open access: yesEpigenetics, 2019
Many cancer therapies operate by inducing double-strand breaks (DSBs) in cancer cells, however treatment-resistant cells rapidly initiate mechanisms to repair damage enabling survival.

The effect of irradiation with swift heavy ions on the structural and morphological properties of beryllium oxide ceramics

open access: yesEurasian Journal of Physics and Functional Materials, 2021
In this study the results of structural and morphological changes in Ni12+ heavy ion irradiated BeO ceramics are presented. Irradiation was carried out on DC-60 heavy ion accelerator using Ni12+ ions with an energy of 100 MeV with irradiation fluence of ...

Epoxy resin with glycidyl-methacrylate-modified boron nitride nanosheets for radiation resistance

open access: yesFushe yanjiu yu fushe gongyi xuebao, 2022
Epoxy resin (EP) has good mechanical and insulating properties and is widely used in the aerospace and nuclear industry. However, it can become degraded and failure-prone in high-energy radiation environments.

Effects of Structural Radiation Disorder in the Near-Surface Layer of Alloys Based on NbTiVZr Compounds Depending on the Variation of Alloy Components

open access: yesCrystals, 2023
This research investigated how changes in the composition of Nb–Ti–V–Zr-based alloys affect their resistance to radiation damage and the preservation of strength characteristics when exposed to the heavy ions Kr15+ and Xe23+.

The effect of added O_2 on the transmittance and radiation resistance of radiation resistant glasses

open access: yesOptics Express, 2010
One method of hardening optical glasses against radiation-induced darkening has been to add CeO(2) to the batch composition. In the present investigation we prepared a series of lanthanum crown glasses with varying degrees of CeO(2) additions and melted them at 1,400 °C with and without bubbling oxygen gas.

Output Power Limit in Energy Harvesting Systems Based on Magnetic Induction Incorporating High-Frequency Effects

open access: yesInstruments, 2019
Wireless power transfer systems based on magnetic induction are usually modeled using the magneto-quasi-static approximation, and by neglecting skin effects and radiation losses.

Effect of physiological age on radiation resistance of some bacteria that are highly radiation resistant [PDF]

open access: yesApplied and Environmental Microbiology, 1984
Physiological age-dependent variation in radiation resistance was studied for three bacteria that are highly radiation resistant: Micrococcus radiodurans, Micrococcus sp. isolate C-3, and Moraxella sp. isolate 4. Stationary-phase cultures of M. radiodurans and isolate C-3 were much more resistant to gamma radiation than were log-phase cultures.

Radiation Resistance: Resurrection by Recombination [PDF]

open access: yesCurrent Biology, 2007
Adaptation to extreme desiccation has conferred extraordinary radiation resistance on the bacterium Deinococcus radiodurans. How this organism is able to reconstruct a genome shattered by gamma rays has now been revealed.
