Advances in organic UV filters for sunscreens over the past decade

open access: yesPhotochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

From Oral Candidiasis to Candidemia: A Review of Superficial to Invasive Progression

open access: yesMicrobiologyOpen, Volume 15, Issue 4, August 2026.
Recent and limited evidence indicates that oral candidiasis can disseminate Candida albicans throughout the body, leading to invasive candidiasis, such as candidemia, a life‐threatening infection. Considering antifungal resistance and global outbreaks of emergent non‐albicans Candida and related yeasts, murine models help understand dissemination ...

De novo or Salvage? Nucleotide Availability as a Driver of Bacterial Adaptation and Virulence

open access: yesMicrobiologyOpen, Volume 15, Issue 4, August 2026.
Bacterial pathogens survive in different host environments by switching between making nucleotides by de novo synthesis and scavenging them from the host. This flexibility supports growth and virulence making nucleotide metabolism an attractive therapeutic target.
