The challenges of developing and optimising an assay to measure 25-hydroxyvitamin D in salivaWe have developed an LC-MS/MS assay that accurately measures saliva 25(OH)D3 levels, which correlated with serum levels

Exposure to Solar UVR Suppresses Cell-Mediated Immunization Responses in Humans: The Australian Ultraviolet Radiation and Immunity StudyHigher UVR exposure at antigen sensitization was associated with a reduced delayed-type hypersensitivity response and altered T helper type 17 kinetics
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

Cellular and molecular mechanisms of vitamin D in food allergyEpidemiological evidence from the past decade suggests a role of vitamin D in food allergy pathogenesis
Research
Vitamin D is crucial for maternal care and offspring social behaviour in ratsThese data highlight that early life levels of vitamin D are an important consideration for maternal behavioural adaptations as well as offspring neuropsychiatry

Molecular actions of Vitamin D in reproductive cell biologyThe aim of this work is to review current metabolic and molecular aspects of the VitD-VitD receptor axis in reproductive medicine

Predictors of vitamin D-containing supplement use in the Australian population and associations between dose and serum 25-hydroxyvitamin D concentrationsThe prevalence of vitamin D-containing supplement use was generally low in the Australian population, particularly for single vitamin D supplements

Self-Reported Changes in Sun-Protection Behaviors at Different Latitudes in AustraliaThe strongest determinants of self-reported sun-protection behavior changes due to concerns about vitamin D were attitudes and location
