Gender differences in DNA damage/repair after laser-generated ultrafast electron beam irradiation
The laser-generated electron acceleration is a developing technology, which can make a revolution in radiation therapy of tumors. The possibility of creating directed ultra-short pulses of enormous capacity (up to kGy/s) allows the precise dose-control induction of local effects on solid tumors with minimal exposure of normal tissues. The obvious advantage of laser-generated electron accelerators is also the significantly smaller size and cost than that of conventional radiotherapy machines.1 There are only a few publications on the biological effects of ultra-short pulsed electron beam radiation.2–5 However, before translating the usage of lasergenerated accelerators into clinical practice, the radiobiological effectiveness of such ultra-short electron bunches should be approved.
The role of women scientists in the development of ultrashort pulsed laser technology-based biomedical research in Armenia
Abstract Purpose To describe the contribution of women scientists in the development of biomedical studies conducted on research facilities based on the ultrashort pulsed laser technologies in Armenia. Conclusion Given the opportunities provided by the ultrashort pulsed laser driven two-photon microscopy and electron beam linac facilities at CANDLE Synchrotron Research Institute, the Armenian women scientists initiated and conducted interdisciplinary research to understand of the biomedical effects of ultrashort pulsed electron beam irradiation, as well as to experience and apply the advantages of the two-photon microscopy in their fields of research. Women scientists had a crucial role and unique impact in the development of ultrashort pulsed laser technology-based biomedical studies in Armenia.
Electron Irradiation Effects on Ferroelectric Copolymer Langmuir-Blodgett Films
The effect of irradiation on the ferroelectric properties of Langmuir-Blodgett films of the copolymer poly(vinylidene fluoride-trifluoroethelene) is investigated using 1.26 MeV electrons with dosages from 16 to 110 Mrad. Irradiation causes a systematic decrease in the phase transition temperature, coercive field and polarization of these thin films.
