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
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

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.

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.

Maternal serum vitamin D levels during pregnancy and offspring neurocognitive developmentThe objective was to determine the association between maternal serum 25(OH)-vitamin D concentrations and behavioural, emotional and language outcomes...
Research
Ultraviolet radiation, vitamin D and multiple sclerosisRecent work highlights both vitamin D and non-vitamin D effects on cellular immunity that suggests that higher levels of sun exposure and/or vitamin D status...

Measuring exposure to solar ultraviolet radiation using a dosimetric technique: Understanding participant compliance issuesWe investigated the types and determinants of noncompliance associated with a protocol for use of polysulphone UVR dosimeters.

Vitamin D status and predictors of serum 25-hydroxyvitamin D concentrations in Western Australian adolescentsUsing prospective data from the Western Australian Pregnancy Cohort (Raine) Study, we investigated vitamin D status and predictors of serum 25-hydroxyvitamin...

House dust mite induced lung inflammation does not alter circulating vitamin D levelsWe hypothesized that allergic inflammation decreases the level of circulating 25(OH)D and tested this using a mice model of house dust mite (HDM) induced...
