Solar ultraviolet radiation in a changing climateThis review article examines risks and benefits of exposure to ultraviolet radiation for the environment and human welfare.
Research
Acute Erythemal Ultraviolet Radiation Causes Systemic Immunosuppression in the AbsenceVitamin D is synthesised by ultraviolet (UV) irradiation of skin and is hypothesized to be a direct mediator.
Research
The relationship between ambient ultraviolet radiation (UVR) and objectively measured personal UVR exposure dose is modified by season and latitudeSeason and latitude modify the relationship between ambient ultraviolet radiation and personal ultraviolet radiation exposure
Research
Modulation of the immune system by UV radiation: More than just the effects of vitamin D?Humans obtain most of their vitamin D through the exposure of skin to sunlight
Research
Prevalence and predictors of vitamin D deficiency in a nationally representative sample of Australian adolescents and young adultsVitamin D deficiency is a public health concern worldwide. Maintaining vitamin D sufficiency during growth periods is essential. We aimed to determine the prevalence and predictors of vitamin D deficiency in Australian adolescents and young adults.
Research
Expression of CYP24A1 and other multiple sclerosis risk genes in peripheral blood indicates response to vitamin D in homeostatic and inflammatory conditionsAlthough genetic and epidemiological evidence indicates vitamin D insufficiency contributes to multiple sclerosis (MS), and serum levels of vitamin D increase on treatment with cholecalciferol, recent metanalyses indicate that this vitamin D form does not ameliorate disease. Genetic variation in genes regulating vitamin D, and regulated by vitamin D, affect MS risk.
Research
Sun-immune connectionExposure to ultraviolet radiation damages skin cell DNA but skin cancers develop because ultraviolet radiation also affects the immune system
Research
Vitamin D C3-epimer levels are proportionally higher with oral vitamin D supplementation compared to ultraviolet irradiation of skin in mice but not humansThe proportion of 25(OH)D3 that undergoes epimerization is greater with oral vitamin D3 supplementation than exposure to UVR in mice, but not in humans
Research
Ultraviolet irradiation of skin alters the faecal microbiome independently of vitamin D in miceSkin exposure to ultraviolet radiation alters the faecal microbiome, and further investigations to explore the implications of this in health and disease are warranted

Tightrope walking: Using predictors of 25 (OH)D concentration based on multivariable linear regression to infer associations with health risksThe approach of predicted 25 (OH)D concentration derived from multivariable linear regression may be valid..
