Chemistry – A European Journal, Volume 32, Issue 1, 2 January 2026.HXE modulates Cu(Aβ) interaction, reducing ROS production and shifting peptide aggregation in the presence of Cu from toxic amorphous aggregates to less harmful fibrillar structures. These findings highlight HXE potential to interfere with Cu‐induced oxidative stress and aggregation pathways relevant to AD.

PLOS ONE, 2018 Paracoccidioidomycosis (PCM) is a neglected human systemic disease caused by species of the genus Paracoccidioides. The disease attacks the host's lungs and may disseminate to many other organs. Treatment involves amphotericin B, sulfadiazine, trimethoprim-sulfamethoxazole, itraconazole, ketoconazole, or fluconazole.

Advanced Science, Volume 13, Issue 3, 14 January 2026.This study presents heparin‐derived nanoparticles (HP‐NPs) as a novel precision medicine platform that combines therapeutic and delivery functions. HP‐NPs target drug‐resistant glioblastoma stem cells, reprogramming them into a drug‐sensitive phenotype and significantly reducing tumor progression.

Targetability of hyaluronic acid nanogel to cancer cells: In vitro and in vivo studies [PDF]
, 2017 We have, in previous work developed, characterized and evaluated the biocompatibility of an engineered hyaluronic acid nanogel. Here we assess the targetability of a hyaluronic acid nanogel towards CD44 overexpressing cells, in vitro and in vivo. Results
