July 2021 in “International Journal of Pharmaceutics” This study describes the development of microneedle array patches for finasteride that released the drug over 7 to 14 days in vitro, suggesting a potential alternative to oral treatments for long-term management of benign prostatic hyperplasia and androgenic alopecia.
July 2023 in “bioRxiv (Cold Spring Harbor Laboratory)” This study reports that a low concentration of chitosan induces callose deposition and slows root hair growth in Arabidopsis, suggesting an evolutionary conservation of this response to mild biotic stress across plant types.
November 2024 in “Journal of Microscopy” This study found that micro-computed tomography (micro-CT) was highly effective for analyzing the cross-sectional geometry of hair fibres, including the medulla in highly curled hair, but less effective than scanning electron microscopy for surface details.
