Diabetic wounds are characterized by chronic inflammation, reduced angiogenesis, and insufficient collagen deposition, leading to impaired healing. Extracellular vesicles (EVs) derived from adipose-derived mesenchymal stem cells (ADSC) offer a promising cell-free therapeutic strategy, yet their efficacy and immunomodulation can be enhanced through bioactivation. In this study, we developed calcium silicate (CS)-stimulated ADSC-derived EVs (CSEV) incorporated into collagen hydrogels to create a sustained-release system for promoting diabetic wound healing.

Efficient degradation of lignocellulosic biomass is key for the production of value-added products, contributing to sustainable and renewable solutions. This study employs a two-step approach to evaluate lignocellulolytic enzymes of Ceratocystis paradoxa, Colletotrichum falcatum, and Sporisorium scitamineum. First, an in silico genomic analysis was conducted to predict the potential enzyme groups produced by these fungi.

Chronic wound healing is often hindered by long-term inflammation and redox imbalance. Herbal medicine, with its rich medicinal components such as polysaccharides, flavonoids, phenolic acids, and small-molecule nutrients, has gained attention for its anti-inflammatory and antioxidant properties. Xanthium strumarium (XS) is a potent anti-inflammatory herb that has shown promise in treating conditions like rhinitis and may have specific benefits for chronic skin wounds.

Intratumoral drug delivery systems hold immense promise in overcoming the limitations of conventional IV chemotherapy, particularly in enhancing therapeutic efficacy and minimizing systemic side effects. In this study, we introduce a novel redox-responsive intratumoral nanogel system that combines the biocompatibility of natural polysaccharides with the tailored properties of synthetic polymers. The nanogel features a unique cross-linked architecture incorporating redox-sensitive segments, designed to leverage the elevated glutathione levels in the tumor microenvironment for controlled drug release.

Magnetic nanoparticles effectively target drug delivery, contrast agents, biosensors, and more. Urchin-like magnetic nanoparticles (UMN) with abundant spike-like structures exhibit superior magneto-mechanical force to destroy tumor cells compared with other shapes of magnetic nanoparticles. However, when cell contents are released from tumor cells induced by magneto-mechanical force, they can act on surrounding tumor cells to facilitate tumor development.
