Maps of solar erythemal ultraviolet (EUV) irradiance daily doses were created for every month with a horizontal resolution of 500 m at the geographical domain 47.15 N–49.86 N×16.94 E–22.81 E covering the territory of Slovakia. The cloud modification factor for the EUV radiation (cmfUV ) was modeled utilizing the relation between the cloud modification factor of global and EUV radiation. The map...

OBJECTIVES Accumulation of apoptotic cells has been suggested to be involved in the pathogenesis of systemic lupus erythematosus (SLE). As sunlight exposure is one of the factors that can trigger disease activity, we hypothesized that UV light may induce increased numbers of apoptotic cells in SLE. METHODS Fourteen SLE patients and 16 controls were irradiated with UVB to determine their minim...

The activation of endogenous double-stranded RNA (endo-dsRNA) signalling pathways is linked to a variety autoimmune diseases. Here, we investigated the role dsRNA in psoriasis by quantifying binding protein (DRBP) mRNA and mitochondrial formation response narrow-band UVB (NB-UVB) treatment. RNAseq data from 34 psoriatic patients treated with NB-UVB were analysed. Biopsies obtained four sites 24...

This paper evaluates the relationship between the cloud modification factor (CMF) in the ultraviolet erythemal range and the cloud optical depth (COD) retrieved from the Aerosol Robotic Network (AERONET) “cloud mode” algorithm under overcast cloudy conditions (confirmed with sky images) at Granada, Spain, mainly for non-precipitating, overcast and relatively homogenous water clouds. Empirical C...

The effects of acute, multiple, and chronic exposure of hairless mice to ultraviolet radiation (UVR) on induction of epidermal ornithine decarboxylase (ODC) (EC 4.1.1.17) activity were investigated. Acute UVR exposure results in a biphasic time course of induction of epidermal ODC activity. Enzyme activity maxima occur at 3 and 24 h postirradiation. The biphasic time course is observed in two d...

UV radiation exposure increases skin cancer risk. A substantial portion of a person's UV exposure occurs before the age of 18 years. We sought to determine UVB radiation exposure levels in high-school students during normal daily activity. Digital dosimeters were worn by 4 high-school students during 11 school days. Students were subjected to daily erythemal and suberythemal doses of UVB radiat...
