Current insights and future perspectives of ultraviolet radiation (UV) exposure: Friends and foes to the skin and beyond the skin.

open access: yesEnvironment International
Ultraviolet (UV) radiation is ubiquitous in the environment, which has been classified as an established human carcinogen. As the largest and outermost organ of the body, direct exposure of skin to sunlight or UV radiation can result in sunburn ...

Multiple roles for UV RESISTANCE LOCUS8 in regulating gene expression and metabolite accumulation in arabidopsis under solar ultraviolet radiation [PDF]

open access: yes, 2013
Photomorphogenic responses triggered by low fluence rates of ultraviolet B radiation (UV-B; 280–315 nm) are mediated by the UV-B photoreceptor UV RESISTANCE LOCUS8 (UVR8).

Ultraviolet-B radiation induces cell death in root tips and reprograms metabolism in Arabidopsis

open access: yesBiologia Plantarum, 2020
Ultraviolet-B (UV-B) radiation inhibits root system growth, however, the influence of UV-B radiation on the regulation of root development remains unclear.

EFFECT OF SOLAR UV RADIATION ON ANTIOXIDANT ENZYMES AND PHENOLS BIOSYNTHESIS IN LETTUCE (Lactuca sativa) [PDF]

open access: yesArab Universities Journal of Agricultural Sciences, 2015
This study aims to evaluate the effect of solar UV radiation on defensive enzymes activities in lettuce seedlings. Seeds of lettuce were grown in high tunnels for 35 days, exposed to three different levels of solar UV, created by using three different ...

UV-B Radiation Effects on the Alpine Plant Kobresia humilis in a Qinghai-Tibet Alpine Meadow

open access: yesPlants, 2022
Enhanced UV-B radiation resulting from stratospheric ozone depletion has been documented both globally and on the Qinghai-Tibet Plateau in China. The response of Kobresia humilis, an important alpine meadow plant species, to enhanced UV-B radiation was ...

The bolometric and UV attenuation in normal spiral galaxies of the Herschel Reference Survey [PDF]

open access: yes, 2015
The dust in nearby galaxies absorbs a fraction of the UV-optical-near-infrared radiation produced by stars. This energy is consequently re-emitted in the infrared.

Overview on topical 5-ALA photodynamic therapy use for non melanoma skin cancers [PDF]

open access: yes, 2014
Ultraviolet radiation (UV) contributes to a variety of skin diseases including inflammation, degenerative aging, and cancer. Historically, humans have been exposed to UV radiation mainly through occupational exposure; recreational UV exposure, however ...

Metabolomic Analysis of Elymus sibiricus Exposed to UV-B Radiation Stress

open access: yesMolecules
Plants cultivated on the Qinghai-Tibet Plateau (QTP) are exposed to high ultraviolet radiation intensities, so they require effective mechanisms to adapt to these stress conditions.

UV Radiation Induces Specific Changes in the Carotenoid Profile of Arabidopsis thaliana

open access: yesBiomolecules, 2022
UV-B and UV-A radiation are natural components of solar radiation that can cause plant stress, as well as induce a range of acclimatory responses mediated by photoreceptors.

On the role of the UV and X-ray radiation in driving a disk wind in X-ray binaries [PDF]

open access: yes, 2001
X-ray heating of the photosphere of an accretion disk is a possible mechanism to produce strong, broad UV emission lines in low mass X-ray binaries (LMXBs).
