Proton beam irradiation inhibits the migration of melanoma cells. [PDF]

PLoS ONE, 2017
In recent years experimental data have indicated that low-energy proton beam radiation might induce a difference in cellular migration in comparison to photons.

Proton irradiation of swept-charge devices for the Chandrayaan-1 X-ray Spectrometer (C1XS) [PDF]

, 2007
This paper presents work carried out in support of swept-charge device (SCD) characterisation for the Chandrayaan-1 X-ray Spectrometer (C1XS) instrument. A brief overview of the C1XS instrument is presented, followed by a description of SCD structure and

Whole brain proton irradiation in adult Sprague Dawley rats produces dose dependent and non-dependent cognitive, behavioral, and dopaminergic effects

Scientific Reports, 2020
Proton radiotherapy causes less off-target effects than X-rays but is not without effect. To reduce adverse effects of proton radiotherapy, a model of cognitive deficits from conventional proton exposure is needed.

Impact of process-dependent SiNx passivation on proton-induced degradation in GaN MIS-HEMTs

Results in Physics, 2021
In this study, AlGaN/GaN heterojunction-based metal–insulator-semiconductor high-electron-mobility transistors (MIS-HEMTs) were fabricated using silicon nitride (SiN) passivation layer.

Mutagenic Effect of Proton Beams Characterized by Phenotypic Analysis and Whole Genome Sequencing in Arabidopsis

Frontiers in Plant Science, 2021
Protons may have contributed to the evolution of plants as a major component of cosmic-rays and also have been used for mutagenesis in plants. Although the mutagenic effect of protons has been well-characterized in animals, no comprehensive phenotypic ...

Proton Irradiation Increases the Necessity for Homologous Recombination Repair Along with the Indispensability of Non-Homologous End Joining

Cells, 2020
Technical improvements in clinical radiotherapy for maximizing cytotoxicity to the tumor while limiting negative impact on co-irradiated healthy tissues include the increasing use of particle therapy (e.g., proton therapy) worldwide.
