    1. Estimating Sun Exposure of Children in Day Care Nurseries in South Oxfordshire, UK

      The aim of this study was to assess variations in the available erythema effective radiant doses to young children in day care nurseries in South Oxfordshire, UK over 7 years between 2008 and 2014. The data were analyzed in three distinct seasons according to a series of realistic exposure scenarios, taking into account nursery routines. The results indicate the time of year when high doses are to be expected and provide strong support for arguments in favor of raising public awareness of sun protection earlier in the year.

    1. Oxidative Modification in Human Hair: The Effect of the Levels of Cu (II) Ions, UV Exposure and Hair Pigmentation

      Anita J. Grosvenor, Jennifer Marsh, Ancy Thomas, James A. Vernon, Duane P. Harland, Stefan Clerens and Jolon M. Dyer

      Article first published online: 5 NOV 2015 | DOI: 10.1111/php.12537

      Human hair is exposed to a wide range of potentially modifying or damaging factors through daily routine, including sunlight and chemicals. This study describes molecular mapping of the effects of UV insult on the proteins of human hair, and how this modification varies with varying levels of copper (II) ions (introduced through washing) and differing levels of hair pigmentation. Advanced redox proteomic approaches were used to locate and track protein oxidation and correlate this modification to hair treatment.

    3. Fluorinated Photodynamic Therapy Device Tips and their Resistance to Fouling for In Vivo Sensitizer Release

      Ashwini A. Ghogare, Joann M. Miller, Bikash Mondal, Alan M. Lyons, Keith A. Cengel, Theresa M. Busch and Alexander Greer

      Article first published online: 4 NOV 2015 | DOI: 10.1111/php.12538

      A one-step process (i.e. simultaneous delivery of sensitizer, oxygen and light) has been developed to simplify the application of PDT. We have analyzed the potential fouling of the PDT device tips with biomaterial from SQ20B squamous cell carcinoma tumors and whole blood. Measurements included sensitizer output inhibition and also biomaterial adhesion by a bicinchoninic acid assay and X-ray photoelectron spectroscopy. A fluorinated device tip led to improved biofouling resistance based on sensitizer photorelease performance and other factors.

    1. Sensitivity of UV Erythemal Radiation to Total Ozone Changes under Different Sky Conditions: Results for Granada, Spain

      Manuel Antón, Alberto Cazorla, David Mateos, Maria J. Costa, Francisco J. Olmo and Lucas Alados-Arboledas

      Article first published online: 4 NOV 2015 | DOI: 10.1111/php.12539

      The analysis of the sensitivity of UV erythemal radiation (UVER) to total ozone changes during different sky conditions differs if the analysis is performed in relative terms (from the RAF) or in absolute terms (from the OE). Both RAF and OE exhibit a great dependence on the cloud optical depth (COD) during overcast conditions, but with opposite sign: while RAF increases with increasing COD, the OE substantially reduces its value as COD increases. To sum up, the UVER sensitivity to ozone changes is strongly affected by the sky conditions related to the cloud cover.
