Sun exposure: An environmental preventer of metabolic dysfunction?

Emerging preclinical findings suggest that some sun exposure is necessary for optimal metabolic health

The inhibitory and inactivating effects of visible light on SARS-CoV-2: A narrative update

Prior to the coronavirus disease-19 pandemic, the germicidal effects of visible light were well known. This review provides an overview of new findings that suggest there are direct inactivating effects of visible light - particularly blue wavelengths on exposed severe acute respiratory syndrome coronavirus 2 virions, and inhibitory effects on viral replication in infected cells. These findings complement emerging evidence that there may be clinical benefits of orally administered blue light for limiting the severity of COVID-19.

Latitudinal gradient in childhood diabetes

New research from Perth's The Kids Research Institute Australia has shown the local relevance of a worldwide pattern of increased risk of childhood type 1 diabetes.

A Gender Lens on User Quality Ratings From Young Teenagers Assessing the Sun Safe App: Comparing Responses From Co-researchers and Participants of Pilot Intervention Studies

We developed the iOS smartphone app Sun Safe to support healthy sun practices in young teenagers (aged 12-13 years). The production involved co-design with young co-researchers (ie, aged 12-13 years) with a health message of using sun protection when the UV index is ≥3. Important features include real-time and location-specific weather data on the UV index and gamified educational content.

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

Prostaglandin E2 imprints a long-lasting effect on dendritic cell progenitors in the bone marrow

Injection of BM-differentiated DCs from nonchimeric mice restored the reduced immune responses of PGE2-chimeric mice.

Reduced immune responses in chimeric mice engrafted with bone marrow cells from mice with airways inflammation.

During respiratory inflammation, it is generally assumed that dendritic cells differentiating from the bone marrow are immunogenic rather than immunoregulatory.

Sub-erythemal ultraviolet radiation reduces metabolic dysfunction in already overweight mice

Exposure to sunlight may limit cardiometabolic risk.

Differences in control by UV radiation of inflammatory airways disease in naïve and allergen pre-sensitised mice

Exposure of skin to UV radiation (UVR) prior to allergen exposure can inhibit inflammatory airways disease in mice by reducing effector CD4+ T cells in both...

Profiling epithelial viral receptor expression in amniotic membrane and nasal epithelial cells at birth

Children with wheeze and asthma present with airway epithelial vulnerabilities, such as impaired responses to viral infection. It is postulated that the in utero environment may contribute to the development of airway epithelial vulnerabilities.
