The aim of this study was to evaluate long-term stability and assess the wound healing potential of the innovative melatonin-loaded lipid-enriched hybrid system compared to conventional melatonin-loaded chitosan microspheres. The hybrid system contained nanostructured lipid carrier incorporated in the chitosan matrix, in order to modify melatonin release and alter physicochemical characteristics of the delivery system. Stability testing was performed during a six-month period under two conditions: refrigerated (5 ± 3 °C) and at room temperature (25 ± 2 °C/60 ± 5 % RH). Samples stored at both conditions were analyzed in terms of particle size, zeta potential, moisture content and thermal properties. At the end of testing, drug content was determined in all samples. Dressings wound healing potential was assessed by in vitro scratch test using human skin fibroblast cell line. Although both systems showed good stability characteristics, the addition of lipids in the system has improved its wound healing potential.

Open wounds are one of the concerns of modern medicine. Early on, before the wound has closed, bacteria can easily enter, leading to bacterial infections. Excipients with antimicrobial effects can greatly facilitate the wound healing process.

Platelet-derived extracellular vesicles (PEVs) are rich in growth factors and have significant potential for facilitating tissue repair and regeneration. Therefore, we conducted this meta-analysis to assess the efficacy of PEVs in treating diabetic wounds. To assess the efficacy and safety of PEVs in treating diabetic wounds, we conducted a systematic review of several databases and performed a meta-analysis using a random effects model.

Background: The periosteum is the main organ responsible for bone regeneration. Vascularized Periosteal Grafts (VPG) have demonstrated exceptional efficacy and speed in facilitating bone union among children with challenging bone healing conditions. Despite their promising results, the overall impact of these interventions has yet to be comprehensively evaluated through systematic review.
