Gene Expression Profiles in Radiation Workers Occupationally Exposed to Ionizing Radiation
(JAPAN RADIATION RESEARCH SOC, 2009)
Ionizing radiation OR) imposes risks to human health and the environment. IR at low doses and low (lose rates has the potency to initiate carcinogenesis. Genotoxic environmental agents such as IR trigger a cascade of signal ...
The genotoxic effects of DNA lesions induced by artificial UV-radiation and sunlight
(ELSEVIER SCIENCE SA, 2010)
Solar radiation sustains and affects all life forms on Earth. The increase in solar UV-radiation at environmental levels, due to depletion of the stratospheric ozone layer, highlights serious issues of social concern. This ...
Effects of UV-B radiation on the antagonistic ability of Clonostachys rosea to Botrytis cinerea on strawberry leaf disc
(2013)
Human activities are altering the concentrations of ozone in the troposphere and hence in the incidence of ultraviolet-B (UV-B) on Earth’s surface. Although representing only five percent of UV-B radiation striking the ...
Possible radio-protective effect of folic acid supplementation on low dose ionizing radiation-induced genomic instability in vitro
(National Institute of Science Communication, 2016-08)
Ionizing radiation induces DNA damage through the production of single-strand breaks, double-strand breaks and reactive oxygen species. Folic acid (FA) can prevent DNA damage. We hypothesized that in vitro supplementation ...
Effects of 60Co gamma radiation on crotamine
(Associação Brasileira de Divulgação Científica (ABRADIC), 2001-12-01)
Ionizing radiation can change the molecular structure and affect the biological properties of biomolecules. This has been employed to attenuate animal toxins. Crotamine is a strongly basic polypeptide (pI 10.3) from Crotalus ...
Improving photoprotection of Beauveria bassiana conidia for biological control of the cactus pest Dactylopius opuntiae in the semiarid region northeast of Brazil
(Taylor & Francis Ltd, 2011-01-01)
A technical grade conidial preparation of the entomopathogenic fungus Beauveria bassiana isolate LCB63 was exposed to ultraviolet light ( UV) from artificial and natural sources in the presence of various photoprotectants ...
Effects of stratospheric ozone depletion, solar UV radiation, and climate change on biogeochemical cycling: interactions and feedbacks
(Royal Society of Chemistry, 2015-01)
Climate change modulates the effects of solar UV radiation on biogeochemical cycles in terrestrial and aquatic ecosystems, particularly for carbon cycling, resulting in UV-mediated positive or negative feedbacks on climate. ...
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 ...
A New Generation of X Ray Irradiators for Insect Sterilization
(ENTOMOLOGICAL SOC AMER, 2010)
Recent fears of terrorism have provoked an increase in delays and denials of transboundary shipments of radioisotopes. This represents a serious constraint to sterile insect technique (SIT) programs around the world as ...
