Quercetin inhibits UV irradiation-induced inflammatory cytokine production in primary human keratinocytes by suppressing NF-kappa B pathway
(ELSEVIER IRELAND LTD, 2011)
Background: Topical flavonoids, such as quercetin, have been shown to reduce ultraviolet (UV) irradiation-mediated skin damage. However, the mechanisms and signaling pathways involved in this protective effect are not ...
Physiotherapy elastic band disinfection by UV-C irradiation in an intensive care unit
(2021-06-01)
Background: The transmission of healthcare-associated pathogens is mainly related to the massive flow of patients with infections in hospitals, presenting surfaces as potential transmission sources of these microorganisms. ...
Influence of irradiation sources on the efficiency of copper-modified magnetite for photo-Fenton degradation of sulfathiazole
(2020-01-01)
A comparison of the catalytic activity of the copper-modified magnetite was carried out under different conditions (dark and irradiated) and irradiation systems (460 nm Vis-LED, 370 nm UV-LED and Solar) in the degradation ...
Thermally Stimulated Discharge of UV-irradiated Corona-charged Teflon FEP Films
(1992-01-01)
UV-irradiated Teflon FEP films, one side metalized and negatively corona charged, show peak shifts in their thermally stimulated discharge (TSD) curves as compared with those of unirradiated samples. They are practically ...
Global and Direct UV Irradiance Variation in the Nahuel Huapi National Park (Patagonia, Argentina) After the Eruption of Puyehue- Cordon Caulle (Chile)
(Elsevier, 2014-02-25)
On June 4th, 2011, the Puyehue-Cordon Caulle volcanic complex (40ª35´25′′S 72ª07´02′′W, Chile) started eruption, sending ash 45,000 feet into the atmosphere. After the initial period, the eruption continued for several ...
Role of UV-B irradiation dose and intensity on color retention and antioxidant elicitation in broccoli florets (Brassica oleracea var. Italica)
(Elsevier Science, 2017-06)
Postharvest UV exposure has been useful to i) delay senescence and ii) induce the accumulation of bioactive compounds in some vegetable species. However, no studies have been conducted to determine the treatment conditions ...
Structural and morphological changes in Poly(caprolactone)/poly(vinyl chloride) blends caused by UV irradiation
(Springer, 2008-02-01)
Films made from a blend of poly(epsilon-caprolactone) and poly(vinyl chloride) (PCL/PVC) retained high crystallinity in a segregated PCL phase. Structural and morphological changes produced when the films were exposed to ...
Bond strenght of dental adhesive systems irradiated with ionizing irradiation
(2010)
The aim of the present paper was to determine the effect of different types of ionizing radiation on the bond strength of three different dentin adhesive systems. Materials and Methods: One hundred twenty specimens of 60 ...
Physiological effects of postharvest UV treatments: recent progress
(Stewart Postharvest Solutions, 2014-12)
Purpose of review: The goal of this review is to summarize the recent progress on the effects of UV radiation on fruits and vegetables metabolism. Main findings: Effective UV irradiation treatments can delay ripening and ...
