Abstract: Medical swabs incorporating a pH indicator in an absorbent crosslinked hydrogel matrix. The medical swabs can provide for visual monitoring of biological pH. The medical swabs can be used to monitor wounds, such as chronic wounds, burn wounds, surgical wounds, etc., as well as other biological fluids. The swabs can be used for early detection of chronic wounds and/or early detection of bacterial infections.

Abstract: Methods and compositions are described for use in encouraging angiogenesis and skin healing as may be utilized in wound treatment as well as in encouragement of angiogenesis in disease. Compositions include an effective amount of a natural pimarane diterpenoid extract of Hymenocrater elegans, or a derivative, analogue, or homolog thereof. Compounds based upon this natural extract have been found to be highly effective in vascular formation and skin closure while exhibiting low toxicity.

Abstract: Wound dressings, methods for forming the wound dressings, and methods for using the wound dressings are described. Wound dressings include a crosslinked hydrogel matrix and a plurality of porous absorbent microspheres encapsulated in the crosslinked matrix. The hydrogel matrix and the microspheres can include the same or different hydrogel polymers, e.g., alginates or the like. The wound dressings can be used in treating chronic wounds and burn wounds and can promote autolytic debridement.
