Alleviation of photoaging‐associated MMP upregulation, prostanoid biosynthesis, and cell cycle arrest with titanium dioxide, zinc oxide, and inorganic‐only (ZnO + TiO2) sunscreens

Photochemistry and Photobiology, EarlyView.
Inorganic sunscreens containing the UV filters titanium dioxide (TiO2) and/or zinc oxide (ZnO) alleviated various biomarkers of photoaging in human dermal fibroblasts, at a gene and protein level. The study provides novel insights that observe the impact of inorganic photoprotection through the molecular biology of skin.

Possible involvement of keratinocyte‐derived microvesicle particles in human photosensitivity disorders

Photochemistry and Photobiology, EarlyView.
In this model, ROS generated by UVB result in PAFR agonists acting upon the PAFR resulting in MVP generation release via the enzyme aSMase. In photosensitivity, there are increased ROS, resulting in augmented PAF agonists and increased MVP release. This process can be blocked by aSMase inhibitors.

The role of constitutive nitric‐oxide synthase in regulation of IKKα after ultraviolet irradiation

Photochemistry and Photobiology, EarlyView.
cNOS enhances IKKα expression following UVB exposure by promoting promoter activation, transcriptional elongation, and Ets‐1 stabilization. These actions sustain IKKα levels, reduce UV‐induced skin carcinogenesis, and highlight cNOS as a key protective factor against solar UV damage.

Evaluating tools for predicting and measuring radiometric performance of germicidal ultraviolet systems

Photochemistry and Photobiology, EarlyView.
An evaluation of simulation and measurement tools for germicidal ultraviolet (GUV) systems is presented to inform their design and deployment to control the spread of airborne pathogens. Abstract Germicidal ultraviolet (GUV) air treatment technologies can be effective and safe for reducing airborne disease transmission.

Gas filter correlation radiometry: Report of panel [PDF]

To measure the concentration of a gas in the troposphere, the gas filter radiometer correlates the pattern of the spectral lines of a sample of gas contained within the instrument with the pattern of the spectral lines in the upwelling radiation.
