Variação da concentração de ozônio e efeitos genotóxicos da radiação UV no sul do Brasil
(Universidade Federal de Santa MariaBrasilBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica ToxicológicaCentro de Ciências Naturais e Exatas, 2022-08-26)
Decreases in stratospheric ozone concentration over the last 40 years influenced by the Antarctic ozone hole have altered the incidence levels of solar ultraviolet (UV) radiation in the south of the Southern Hemisphere. ...
Development of a DNA-dosimeter system for monitoring the effects of solar-ultraviolet radiation
(ROYAL SOC CHEMISTRY, 2009)
Solar radiation sustains and affects all life forms on Earth. In recent years, the increase in environmental levels of solar-UV radiation due to depletion of the stratospheric ozone layer, as a result of anthropogenic ...
DNA damage profiles induced by sunlight at different latitudes
(WILEY-BLACKWELLMALDEN, 2012-04)
Despite growing knowledge on the biological effects of ultraviolet (UV) radiation on human health and ecosystems, it is still difficult to predict the negative impacts of the increasing incidence of solar UV radiation in ...
DNA Dosimetry Assessment for Sunscreen Genotoxic Photoprotection
(PUBLIC LIBRARY SCIENCESAN FRANCISCO, 2012)
Background: Due to the increase of solar ultraviolet radiation (UV) incidence over the last few decades, the use of sunscreen has been widely adopted for skin protection. However, considering the high efficiency of ...
Hundred joules plasma focus device as a potential pulsed source for in vitro cancer cell irradiation
(American Institute of Physics, 2017)
Plasma focus devices may arise as useful source to perform experiments aimed to study the effects of pulsed radiation on human cells in vitro. In the present work, a table top hundred joules plasma focus device, namely ...
Hundred joules plasma focus device as a potential pulsed source for in vitro cancer cell irradiation
(American Institute of Physics Inc., 2017-08)
Plasma focus devices may arise as useful source to perform experiments aimed to study the effects of pulsed radiation on human cells in vitro. In the present work, a table top hundred joules plasma focus device, namely ...
In vitro irradiation of colorectal cancer cells by pulsed radiation emitted from a hundred joules plasma focus device and its comparison with continuous irradiation
(Institute of Physics Publishing, 2018)
In the last years, pulsed reduced low dose radiation has been proposed as an alternative for treatment of recurrent cancer. Nonetheless, distinction between the effects of low dose pulsed and continuous radiation is barely ...
Investigating microbial diversity and UV radiation impact at the high-altitude lake Aguas Calientes, Chile
(SPIE, 2007-12)
The High-Lakes Project is funded by the NAI and explores the highest perennial volcanic lakes on Earth in the Bolivian and Chilean Andes, including several lakes ∼6,000 m elevation. These lakes represent an opportunity to ...
