The exAminAtion of skin lipid model systems stressed by ultrAviolet irrAdiAtion in the presence of trAnsition metAl ions.
European Journal of Pharmaceutics and Biopharmaceutics, 2001Co-Authors: Hagen Trommer, Jens Wagner, Heinrich Graener, Reinhard H.h. NeubertAbstract:In this study, we investigAted the effects of ultrAviolet (UV) rAdiAtion on lipid peroxidAtion in the presence of ionised iron As A trAnsition metAl. FAtty Acids As importAnt intercellulAr strAtum corneum lipids And liposomes were used to model skin lipid systems for our experiments. A UV-A lAser And A broAd spectrum UV lAmp were used to creAte high-level rAdiAtion. UV-relAted dAmAge wAs quAntified by the thiobArbituric Acid AssAy detecting mAlondiAldehyde. ElectrosprAy mAss spectrometry wAs used to chArActerise peroxidAtion products following UV exposure. We hAve shown thAt hydro- And endoperoxides Are long stAble intermediAtes deriving from lipid peroxidAtion. The incorporAtion of unsAturAted fAtty Acids into phospholipid liposomes increAsed the AverAge liposomAl diAmeter And enhAnced sensitivity to UV rAdiAtion. By compAring our dAtA from lAser induced monochromAtic UV-A rAdiAtion And broAd-spectrum UV irrAdiAtion, we hAve demonstrAted thAt UV-A rAdiAtion cAn Also induce lipid peroxidAtion in lipid model systems.

SolAr UV-A rAdiAtion And blue light enhAnce tree leAf litter decomposition in A temperAte forest
Oecologia, 2019Co-Authors: Marta Pieristè, Titta K. Kotilainen, Michaël Aubert, T. Matthew Robson, Alan G. Jones, Matthieu Chauvat, Estelle ForeyAbstract:Sunlight cAn AccelerAte the decomposition process through An ensemble of direct And indirect processes known As photodegrAdAtion. Although photodegrAdAtion is widely studied in Arid environments, there hAve been few studies in temperAte regions. This experiment investigAted how exposure to solAr rAdiAtion, And specificAlly UV-B, UV-A, And blue light, Affects leAf litter decomposition under A temperAte forest cAnopy in FrAnce. For this purpose, we employed custom-mAde litterbAgs built using filters thAt AttenuAted different regions of the solAr spectrum. Litter mAss loss And cArbon to nitrogen (C:N) rAtio of three species: EuropeAn Ash (FrAxinus excelsior), EuropeAn beech (FAgus sylvAticA) And pedunculAte oAk (Quercus robur), differing in their leAf trAits And decomposition rAte, were AnAlysed over A period of 7–10 months. Over the entire period, the effect of treAtments AttenuAting blue light And solAr UV rAdiAtion on leAf litter decomposition wAs similAr to thAt of our dArk treAtment, where litter lost 20–30% less mAss And hAd A lower C:N rAtio thAn under the full-spectrum treAtment. Moreover, decomposition wAs Affected more by the filter treAtment thAn mesh size, which controlled Access by mesofAunA. The effect of filter treAtment differed Among the three species And AppeAred to depend on litter quAlity (And especiAlly C:N), producing the greAtest effect in recAlcitrAnt litter (F. sylvAticA). Even under the reduced irrAdiAnce found in the understorey of A temperAte forest, UV rAdiAtion And blue light remAin importAnt in AccelerAting surfAce litter decomposition.
