Exposing the skin to solar UV radiation induces cascades of signaling pathways and biological alterations such as redox imbalance, suppression of antioxidant genes and programmed cell death. Therefore, the aim of this study was to use RNA-Seq to unravel the effects of UV radiation on Normal Human Adult Fibroblast cells (NHDF). Cells were exposed to...

BackgroundSunlight is one of the main harmful exogenous factors that induce the reactive oxygen species formation. The human skin is the first line of photoprotection against harmful exogenous factors, such as UV radiations. The topical application of sunscreens, containing UV-B filters, is widely used to protect against UV-induced damage. Octylmet...
Fotodegradacija odtisa, izdelanega s kapljičnim tiskalnikom, je večplasten proces. Pri tem sodelujejo številni dejavniki: črnilo kot kompleksna mešanica kolorantov in različnih spremljevalnih snovi, papir, ki poleg različnih vlaken vsebuje tudi druge komponente, kot so na primer optična belilna sredstva, ter zunanji dejavniki, kot so temperatura, v...

AbstractKinetic patterns of the degradation of Methyl Orange (MO) dye are studied upon persulfate (PS) and quasi-monochromatic UV radiation (mercury-free source: KrCl-excilamp, 222 nm, referred to below as UV) treatment in the presence or absence of iron ions. Oxidative systems can be placed in the following order according to the efficiency and ra...

UVB radiation results in the formation of potentially mutagenic photoproducts in the DNA of epidermal skin cells. In vitro approaches have demonstrated that the nucleotide excision repair (NER) machinery removes UV photoproducts from DNA in the form of small (∼30-nt-long), excised, damage-containing DNA oligonucleotides (sedDNAs). Though this proce...
Namen doktorske disertacije je bil razviti hitro in učinkovito metodo za napovedovanje zaščitnih lastnosti tkanin pred UV sevanjem že v fazi njihovega načrtovanja oz. projektiranja. Z definiranjem koeficientov prepustnosti (T), odboja (R) in absorpcije (A) ultravijoličnega (UV) sevanja na podlagi razširjene teorije faktorja kritja tkanin je bil nam...
The skin is constantly exposed to a variety of environmental threats, including solar electromagnetic radiation, microbes, airborne particulate matter, and chemicals. Acute exposure to these environmental factors results in the activation of different signaling pathways that orchestrate adaptive stress responses to maintain cell and tissue homeosta...

The responses in growth and defense after tissue damage are highly variable in plants depending on species, damaged-tissue type and the intensity of damage. The prevailing abiotic conditions can also influence these responses. In this study, our aim was to examine how the removal of lateral vegetative buds affects the growth and accumulation of phe...

Melanism is widely observed among animals, and is adaptive in various contexts for its thermoregulatory, camouflaging, mate-attraction or photoprotective properties. Many organisms exposed to ultraviolet radiation show increased fitness resulting from melanin pigmentation; this has been assumed to result in part from reduced UV-induced damage to DN...
