Most of the positive effects of solar radiation are mediated via ultraviolet-B (UVB) induced production of vitamin D in skin. However, several other pathways may exist for the action of ultraviolet (UV) radiation on humans as focused on in this review. One is induction of cosmetic tanning (immediate pigment darkening, persistent pigment darkening and delayed tanning). UVB-induced, delayed tanni...

UV-induced pigmentation (suntanning) requires induction of alpha-melanocyte-stimulating hormone (alpha-MSH) secretion by keratinocytes. alpha-MSH and other bioactive peptides are cleavage products of pro-opiomelanocortin (POMC). Here we provide biochemical and genetic evidence demonstrating that UV induction of POMC/MSH in skin is directly controlled by p53. Whereas p53 potently stimulates the ...

OBJECTIVES To explore whether knowledge about the harms of ultraviolet radiation (UVR) influences UK university students' sun-related behaviours and examine in depth their attitudes towards: sun protection, natural and artificial tanning behaviours. DESIGN Qualitative methodology with 15 semistructured, individual interviews. Thematic analysis using the Framework Method with analyst triangula...

Solid state ¹³C-NMR spectra of pure tannin powders from four different sources--mimosa, quebracho, chestnut and tara--are readily distinguishable from each other, both in pure commercial powder form, and in leather which they have been used to tan. Groups of signals indicative of the source, and type (condensed vs. hydrolyzable) of tannin used in the manufacture are well resolved in the spectra...

BACKGROUND Exposure to UV radiation is associated with cutaneous malignant melanoma (CMM). In mammalian cells, UV radiation induces DNA damage that can be repaired by the nucleotide excision repair system. We designed this case-control study to determine whether DNA repair capacity (DRC) is associated with the risk of CMM and to identify risk factors that may interact biologically with DRC in t...

INTRODUCTION In 2009, ultraviolet-emitting tanning devices, i.e. sunbeds and tanning booths, were officially classified as carcinogenic to human health (Group 1) by the International Agency for Research on Cancer. METHODS Here, we aim to estimate South African-based facilities with indoor tanning services advertised in the printed Yellow Pages and online in two directories. Printed Yellow Pag...

Recently more and more studies have reported high prevalence rates for a 'tanning dependence' among tanning bed users. The authors of these studies base their argumentation on a modified (m) version of the CAGE (Cut-down, Annoyed, Guilty and Eye-opener) Criteria, initially used for alcohol addiction. By means of cognitive interviews and a large population survey, we tested the validity of the m...

Surface charge and isoelectric point of leather play an important role in the production of leather. However, a precise and rapid method for the determination of leather surface charge and isoelectric point is unavailable nowadays due to the complexity of the structure of leather, especially for chromefree tanned leather. Therefore, it is necessary to develop a quantitative determination method...
