Abstract: This study explores novel alginate–konjac glucomannan core–shell aerogel particles for drug delivery systems fabricated via air-assisted coaxial prilling. A systematic approach is needed for the optimization of this method due to the numerous processing variables involved. This study investigated the influence of six variables: alginate and konjac glucomannan concentrations, compressed airflow, liquid pump pressures, and nozzle configuration. A hybrid software using A[...]
Our summary: This study utilizes Artificial Intelligence tools to optimize the fabrication of alginate-konjac glucomannan core-shell aerogel particles for drug delivery systems. The process involves investigating six variables and using a hybrid software to achieve a 100% desirable solution. The resulting aerogels exhibit high specific surface area and are capable of releasing drugs effectively.

Wound dressing
Patent published on the 2025-05-22 in US under Ref US2025161118 by CARL FREUDENBERG KG [DE] (Pehr Marc [de], Schlesselmann Bernd [de], Duncker-rakow Samuel [de])
Abstract: A wound dressing including a needle-punched nonwoven. The needle-punched nonwoven of the wound dressing is 30% to 80% by weight, based on a total weight of the needle-punched nonwoven, superabsorbent fibers. The needle-punched nonwoven of the wound dressing is 70% to 20% by weight, based on the total weight of the needle-punched nonwoven, self-crimped fibers.[...]
Our summary: Wound dressing with needle-punched nonwoven containing superabsorbent and self-crimped fibers in specific weight percentages.

Cervical distraction/implant delivery device
Patent published on the 2025-05-22 in US under Ref US2025161066 by PROVIDENCE MEDICAL TECH INC [US] (Mccormack Bruce M [us], Smith Jeffrey D [us])
Abstract: Systems for distracting a facet joint and positioning a permanent implant in the joint are disclosed. The implants serve to retain a distracted position of the facet joint which is achieved with positioning of the leading end of a distraction tool in the facet joint and then distracting or enlarging the joint a desired amount. The permanent implant could be part of the distraction mechanism which can be separated from the delivery tool once the joint has been distracted or an auxiliary implant m[...]
Our summary: Systems for distracting and positioning permanent implants in facet joints. Implants retain distracted position achieved by distraction tool. Implants may be solid mechanical devices or injected fluids.
