Direct evidence of singlet molecular oxygen [O2 (1Δg)] production from UVA excited 6‐thioguanine

Photochemistry and Photobiology, EarlyView.
6‐Thioguanine (6‐TGua) is incorporated into DNA as a purine analogue, inhibiting cell replication. Patients treated with 6‐TGua are more prone to developing skin cancer due to the photoexcitation of 6‐TGua by UVA radiation (as illustrated in the Jablonski diagram). Upon exposure to UVA, the excited 6‐TGua generates 1O2.

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.

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.

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 ...

Platelet‐rich plasma (PRP) versus injectable platelet‐rich fibrin (i‐PRF): A systematic review across all fields of medicine

Periodontology 2000, EarlyView.
Abstract This systematic review aimed to evaluate all available evidence across all fields of medicine regarding the comparative effectiveness of platelet‐rich plasma (PRP) versus injectable platelet‐rich fibrin (i‐PRF). A comprehensive search was conducted in PubMed, Scopus, and Web of Science up to September 30, 2024.
