Antimicrobial Effect of Platelet‐Rich Fibrin Membranes on Oral Pathogens: An In Vitro Evaluation
International Journal of Dentistry, Volume 2026, Issue 1, 2026.Objective Leukocyte‐ and platelet‐rich fibrin (L‐PRF) has emerged as a bioactive scaffold with regenerative and immunomodulatory properties, though its antimicrobial potential remains underexplored. This study aimed to evaluate in vitro the inhibitory effect of L‐PRF membranes on Streptococcus mutans and Candida albicans in monoculture and coculture ...

Journal of Food Processing and Preservation, Volume 2026, Issue 1, 2026.This study investigated the effects of yarrow (Achillea millefolium) essential oil (YE) and its nanoemulsion (NEYE), at concentrations of 1% and 2%, on oxidative stability and microbial growth of mayonnaise stored for 45 days at 4°C. NEYEs were characterized with a particle size ranging from 75.5 to 152.65 nm, with a polydispersity index (PDI) of 0.7–0.
