Methods for substituting onsite ambient ultraviolet radiation measurements for personal exposure studies

Photochemistry and Photobiology, EarlyView.
Three methods for substituting on‐site ambient ultraviolet radiation measurements for personal exposure measurements were investigated. Assuming spatial persistency of measurements from high‐grade instruments delivers lowest uncertainties up to distances of 82 km.

The effects of far‐UVC irradiation on the presence and concentration of ESKAPEE pathogens on hospital surfaces: Study protocol for a multi‐site, double‐blinded randomized controlled trial in La Paz, Bolivia

Photochemistry and Photobiology, EarlyView.
The protocol of a multi‐site, double‐blinded, clustered randomized controlled trial (cRCT) with a binary outcome of the presence of viable presumptive ESKAPEE pathogens on surfaces in and around hospital sinks is to be implemented in two Bolivian hospitals.

Development of chalcones structure‐related to avobenzone: Photoprotection, photostability, and safety evaluation

Photochemistry and Photobiology, EarlyView.
Scaffold hopping strategy used to develop chalcones structure‐related to the avobenzone tautomer. Positive aspects of 2‐hydroxychalcones are highlighted. Abstract Chalcones are α,β‐unsaturated ketones with extended π‐conjugation, making them promising scaffolds for the development of organic UV filters.

Keratinocytes exposed to ultraviolet A and ultraviolet B radiation induce responses in melanocytes

Photochemistry and Photobiology, EarlyView.
Keratinocyte‐derived soluble factors regulate melanocyte responses following UV exposure. Conditioned medium from irradiated keratinocytes enhances melanocyte mitochondrial activity, cell proliferation, and cell cycle progression while improving survival after UVA‐induced damage.

Platelet‐activating factor‐receptor signaling mediates solar‐simulated light‐induced extracellular vesicle release in human keratinocytes

Photochemistry and Photobiology, EarlyView.
Solar‐simulated light (SSL) promotes extracellular vesicle (EV) release from keratinocytes through a UVB‐driven, oxidative stress‐dependent pathway. SSL‐induced reactive oxygen species (ROS) generate oxidized glycerophosphocholines with PAF agonistic activity, which activate the Platelet‐activating factor receptor (PAFR), leading to acid ...
