Controlled Release of Human Dental Pulp Stem Cell‐Derived Exosomes from Hydrogels Attenuates Temporomandibular Joint Osteoarthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
Exosomes can reduce tissue damage in temporomandibular joint osteoarthritis (TMJOA), but rapid clearance limits their efficacy. This study encapsulates exosomes in hyaluronic acid hydrogels for controlled release. In a rat model, hydrogel‐encapsulated exosomes outperform free exosomes in preserving bone integrity and reducing tissue destruction ...

A Colorimetric Method for the Determination of the Exhaustion Level of Granular Activated Carbons Used in Rum Production

open access: yesBeverages, 2016
Spectrophotometric measurement applied on saturated granular activated carbon (GAC) is not yet explored. A colorimetric method in the visible range has been developed in order to determine the exhaustion level of GAC used in rum production.

Synthetic Bilirubin‐Based Nanomedicine Protects Against Renal Ischemia/Reperfusion Injury Through Antioxidant and Immune‐Modulating Activity

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
BX‐001N, a polyethylene glycol‐conjugated bilirubin 3α nanoparticle, is the first GMP‐grade, synthetic bilirubin‐based nanomedicine. It effectively attenuates acute renal injury, facilitates subacute renal recovery, and suppresses chronic fibrosis after renal ischemia/reperfusion injury via anti‐oxidant and immune‐modulating activity.

Mechanically and Chemically Defined PEG Hydrogels Improve Reproducibility in Human Cardioid Development

open access: yesAdvanced Healthcare Materials, EarlyView.
Synthetic matrix metalloproteinase (MMP)‐degradable polyethylene glycol (PEG)‐based hydrogels are developed to investigate the influence of mechanical and biochemical cues on cardioid development. Matrix stiffness and cell adhesion motifs significantly regulate cardioid formation, chamber morphogenesis, contractile function, and cardioid transcriptome.

HGF/c‐Met Axis‐Targeted Nanotherapy via GSH‐Responsive Polymer Platforms Suppresses Uveal Melanoma Metastasis

open access: yesAdvanced Healthcare Materials, EarlyView.
To suppress uveal melanoma metastasis (UM), the GSH‐responsive polymer named NP@Oxa/Criz has been successfully prepared. NP@Oxa/Criz selectively accumulates in UM tumors, targeting HGF/c‐Met Axis to undermine the stemness and metastasis of UM while triggering immunogenic cell death through DAMPs release to boost anti‐tumor immunity.
