Wavelength dependence of oxidative DNA damage induced by UV and visible light.
DNA damage induced by UV radiation and visible light (290-500 nm) in AS52 Chinese hamster cells was analysed by an alkaline elution assay with specific repair endonucleases. Cells were exposed toExpand
Nutritional skin care: health effects of micronutrients and fatty acids.
Human skin is continuously exposed to internal and external influences that may alter its condition and functioning. As a consequence, the skin may undergo alterations leading to photoaging,Expand
Evidence that DNA damage triggers interleukin 10 cytokine production in UV-irradiated murine keratinocytes.
UV irradiation interferes with the induction of T cell-mediated immune responses, in part by causing cells in the skin to produce immunoregulatory cytokines. Recent evidence implicates UV-induced DNAExpand
Dermal absorption of chlorpyrifos in human volunteers
Objective: The methods and results are described of a study on the dermal absorption of chlorpyrifos (CPF) in humans established via urinary excretion of the metabolite 3,5,6-trichloro-2-pyridinolExpand
(Pheo)melanin photosensitizes UVA-induced DNA damage in cultured human melanocytes.
The question of whether melanins are photoprotecting and/or photosensitizing in human skin cells continues to be debated. To evaluate the role of melanin upon UVA irradiation, DNA single-strandExpand
Different removal of ultraviolet photoproducts in genetically related xeroderma pigmentosum and trichothiodystrophy diseases.
To understand the heterogeneity in genetic predisposition to skin cancer in different nucleotide excision repair-deficient human syndromes, we studied repair of cyclobutane pyrimidine dimers (CPDs)Expand
Enzyme plus light therapy to repair DNA damage in ultraviolet-B-irradiated human skin.
Ultraviolet-B (UVB) (290-320 nm) radiation-induced cyclobutane pyrimidine dimers within the DNA of epidermal cells are detrimental to human health by causing mutations and immunosuppressive effectsExpand
The inhibition of antigen-presenting activity of dendritic cells resulting from UV irradiation of murine skin is restored by in vitro photorepair of cyclobutane pyrimidine dimers.
Exposing skin to UVB (280-320 nm) radiation suppresses contact hypersensitivity by a mechanism that involves an alteration in the activity of cutaneous antigen-presenting cells (APC). UV-induced DNAExpand
Induction of interleukin-6 production by ultraviolet radiation in normal human epidermal keratinocytes and in a human keratinocyte cell line is mediated by DNA damage.
The sunburn reaction is the most common consequence of human exposure to ultraviolet radiation (UVR), and is mediated at least in part by interleukin-6 (IL-6). The aim of this study was to determineExpand
