Spectroscopic analysis of bacterial photoreactivation

Photochemistry and Photobiology, Volume 101, Issue 2, Page 494-504, March/April 2025.
This study investigates the effectiveness of fluorescence and Raman spectroscopy in detecting bacterial photoreactivation. Fluorescence spectroscopy shows limitations, because the intense fluorescence of tryptophan and tyrosine masks fluorescence emitted by thymine molecules.

Exploring natural sunscreens: UVB protection and antioxidant properties in gadusol‐rich fish roes extracts

Photochemistry and Photobiology, EarlyView.
Gadusol‐rich extracts provide effective UVB protection and antioxidant activity in HaCaT cells and C. elegans, highlighting their potential as natural photochemoprotective agents for pharmaceutical and cosmetic applications. It also demonstrates remarkable in vitro antioxidant capacity and thermal stability over time.

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.

Characterization and parameters for the effectiveness of a UV‐C device for infection control in dental clinics

Photochemistry and Photobiology, EarlyView.
Purpose‐built UV‐C device achieves over 90% disinfection of high‐touch dental clinic surfaces. Abstract Healthcare‐associated infections (HAIs) remain a significant concern in dental settings, especially in light of increasing antimicrobial resistance.

Effects of solar‐simulated (UVB plus UVA) radiation on the skin microbiome: An exploratory study

Photochemistry and Photobiology, EarlyView.
This exploratory in vivo study investigated the effects of solar‐simulated ultraviolet radiation (UVB plus UVA) on the human skin microbiome. Healthy male volunteers were exposed to suberythemal and erythemal UV doses, and skin microbiota were analyzed at multiple time points using flow cytometry‐based profiling and the open‐access bioinformatic ...
