In Situ Gels for Nasal Delivery: Formulation, Characterization and Applications

open access: yesMacromolecular Materials and Engineering, Volume 310, Issue 6, June 2025.
Drug delivery through the nasal route offers many advantages, but is hampered by a number of challenges, such as the short drug retention time caused by mucociliary clearance. In situ forming gels, which undergo a sol‐to‐gel transition with specific triggers at the site of action, present real opportunities in this field.

Inbreeding Depression Manifested in Progeny From Fragmented Populations of the Wind‐Pollinated Dioecious Conifer Afrocarpus gracilior (Pilg.) C. N. Page

open access: yesEcology and Evolution, Volume 15, Issue 2, February 2025.
Forest fragmentation in Afrocarpus gracilior reduced genetic diversity and caused significant inbreeding depression, especially in smaller populations. Progeny from these populations showed lower genetic diversity, reduced germination rates, slower growth, and diminished survival. Seeds should be sourced from larger, genetically diverse populations for
