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

Awake and Alert: Examining the Portrayal of Energy Drinks on TikTokEnergy drinks (EDs) are not recommended for minors' consumption due to a myriad of health risks, but marketing initiatives persist. This study explored the promotion of EDs on TikTok, a platform frequented by children and adolescents.

Exposure to UV Wavelengths in Sunlight Suppresses Immunity. To What Extent is UV-induced Vitamin D3 the Mediator Responsible?In experimental models, both vitamin D3-dependent and vitamin D3-independent pathways have been implicated in the mechanisms of UVR-induced systemic...

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.
