The value of Vitamin D

Research has shown that vitamin D levels can have an impact on many aspects of a child's health, including lung growth, language development and eating patterns

Exposure to sunlight could reduce asthma

Australian researchers have found that exposure to measured doses of ultraviolet light, such as sunlight, could reduce asthma.

Developmental vitamin D deficiency increases foetal exposure to testosterone

Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders which are more common in males. The 'prenatal sex steroid' hypothesis links excessive sex-steroid exposure during foetal life with the behavioural differences observed in ASD. However, the reason why sex steroid exposure may be excessive remains unclear. Epidemiological studies have identified several environmental risk factors associated with ASD, including developmental vitamin D (DVD) deficiency.

Characterising nitric oxide-mediated metabolic benefits of low-dose ultraviolet radiation in the mouse: a focus on brown adipose tissue

Non-burning (low-dose) UVR suppresses the BAT 'whitening', steatotic and pro-diabetic effects of consuming a high-fat diet through skin release of nitric oxide

Sun-immune connection

Exposure to ultraviolet radiation damages skin cell DNA but skin cancers develop because ultraviolet radiation also affects the immune system

Inflammatory bowel diseases: interrelationships between dietary vitamin D, exposure to UV radiation and the fecal microbiome

This review explores the interaction of vitamin D, and ultraviolet radiation, with the intestinal innate and adaptive immune systems

The challenges of developing and optimising an assay to measure 25-hydroxyvitamin D in saliva

We 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 Study

Higher UVR exposure at antigen sensitization was associated with a reduced delayed-type hypersensitivity response and altered T helper type 17 kinetics

Vitamin D C3-epimer levels are proportionally higher with oral vitamin D supplementation compared to ultraviolet irradiation of skin in mice but not humans

The 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
