Pre‐Operative Intraoral Ultrasound Features of Benign and Malignant Oral Lesions: An Exploratory Pilot Study

Oral Diseases, EarlyView.
ABSTRACT Objective To evaluate intraoral‐ultrasound (ioUS) features of benign and malignant oral lesions. Methods In this prospective cross‐sectional study, patients with oral soft tissue lesions underwent ioUS followed by biopsy within 2 weeks. Sonographic features: size, echogenicity, cystic areas, calcifications, margins, and vascularity were ...

Prolonged exposure to artificial light and carcinogenesis: A systematic review of oncostatic mechanisms associated with melatonin pathways

Photochemistry and Photobiology, EarlyView.
Exposure to artificial light at night (ALAN), particularly at blue wavelengths, disrupts circadian rhythms by suppressing melatonin, thereby increasing cancer susceptibility. This systematic review consolidates evidence linking prolonged ALAN exposure to an elevated risk of breast and prostate tumors.

RAD51 and RAD51 paralog inhibition sensitizes nonreplicating quiescent keratinocytes to UV radiation

Photochemistry and Photobiology, EarlyView.
UV radiation and other compounds generate DNA adducts that block transcription and induce cell death if not removed by the nucleotide excision repair system. In this work, we used a small‐scale pharmacological screen to discover that inhibition of the recombinase RAD51 sensitized nonreplicating quiescent keratinocytes to both UVR and other agents that ...
