Since nerve termini on Langerhans cells (LC) contain calcitonin gene-related peptide (CGRP), and since ultraviolet B radiation (UVR) causes CGRP to be released from cutaneous nerve endings, we examined whether CGRP participates in the immune aberrations caused in skin by UVR. First, intradermally injected CGRP, in a dose-dependent manner, reduced LC density and impaired CH induction when hapten...

BACKGROUND Ultraviolet radiation (UVR) exposure is the main risk factor for cutaneous malignant melanoma (CMM), but its specific effect in infancy is unknown. We examined whether season of birth, a proxy for solar UVR exposure in the first few months of life, is associated with CMM in childhood through young adulthood. METHODS National cohort study of 3,571,574 persons born in Sweden in 1973-...

ownloade kground: Melanoma incidence has been correlated strongly and positively with both socioeconomic (SES) and lower latitude and other measures of ambient UV radiation (UVR). However, because ES populations may be colocated in areas of high UVR, we assessed their joint influences on melanoma ence to better target subpopulations for melanoma education and screening. thods: We obtained from ...

The apparent immune-suppressive effect of ultraviolet radiation (UVR) has suggested that this environmental exposure may influence the development of immune-related disorders. Self-reported prevalence rates of type 1 diabetes mellitus, rheumatoid arthritis (RA), eczema/dermatitis, and asthma, from the 1995 Australian National Health Survey, were therefore examined by latitude and ambient level ...

Cataract is defined as an opacification of the lens resulting in visual impairment. Worldwide, it is the number one cause of blindness and there are currently no strategies to prevent the onset of the disease. Cataract surgery is the most commonly performed elective intervention in industrialized countries. The condition has thus major impact on national and international health care systems. E...

Background: This article presents an exploratory study, aiming to explore the correspondence between knowledge, motivation and sun-protection practices during holidays. Methods: Seventeen participants aged 21-62 years old, recruited from community settings took part in individual face-to-face semi-structured interviews, completed sun sensitivity questions and an objective assessment of sunscree...

doi: 10.1111/j.1399-3054.2005.00538.x The light-induced de-epoxidation of xanthophylls is an important photoprotective mechanism in plants and algae. Exposure to ultraviolet radiation (UVR, 280–400 nm) can change the extent of xanthophyll de-epoxidation, but different types of responses have been reported. The de-epoxidation of violaxanthin (V) to zeaxanthin (Z), via the intermediate antheraxan...

In Western countries, ultraviolet (UV)-induced skin cancer has been studied extensively regarding the high incidence of skin cancers in the white population; however, for people of color, cataracts are the main public health issue in relation to increased ambient ultraviolet radiation (UVR). To our knowledge, few studies have been conducted examining the relationship between cataracts and ambie...

BACKGROUND WHO's global burden of disease studies, undertaken since 1996, apportion the total global disease burden, measured in disability-adjusted life years (DALYs), to specific diseases and injuries. Recent assessments of the relative burden due to specific environmental risk factors, plus an understanding of the nature of the risk factor, may guide resource allocation in risk factor manage...
