20230302191 · 2023-09-28 · ·

In one aspect, a composition for sustained release of oxygen to a tissue is disclosed that includes at least one core-shell oxygen release microsphere (ORM), wherein the core includes a water-soluble polymer-reactive oxygen species (ROS) complex and the shell includes a biodegradable polymer conjugated to a ROS-scavenging enzyme. In some aspects, the reactive oxygen species includes hydrogen peroxide (H.sub.2O.sub.2), the ROS-scavenging enzyme includes catalase, the water-soluble polymer includes polyvinylpyrrolidone (PVP), and the biodegradable polymer includes poly(N-isopropylacrylamide-co-2-hydroxyethyl methacrylate-co-acrylate-oligolactide-co-Nacryloxysuccinimide)[poly(NIPAAm-co-HEMA-co-AOLA-co-NAS)].

MELT-AND-MELD APPROACH TO REPAIR TISSUE DEFECTS

The present invention is a multi-stage treatment that heals tissue or organ damage (e.g., linear defects, fissures, and fibrillations, as well as focal and large defects) in collagen-rich tissues and organs such as articular cartilage. The present invention includes methods 1) to prime tissues in preparation for treatment, which comprises “melting” the tissue matrix, 2) to add or fill the damaged area with a “melding” agent, comprising of endogenous or exogenous tissue matrix, with or without cells, with or without exogenous biomaterials, and with or without endogenous or exogenous enzymes, such that the melding agent enhances anchoring into the defect for the purpose of integration and/or tissue healing. The Melt-and-Meld process can also be applied in conjunction with any existing treatments of tissue or organ defects.

Method of decellularization of kidney tissues, decellularized material by the method and bioink comprising the decellularized material

The method for decellularization of kidney tissue according to the present invention, the decellularized material produced through the method, and a bioink comprising the decellularized material have the effect of maximizing the effect of kidney treatment by maximizing the content of components specialized for kidney treatment such as the collecting duct and renal tubule of the kidney.

Antimicrobial compositions

Storage-stable compositions for generating antimicrobial activity are described. The compositions comprise an enzyme that is able to convert a substrate to release hydrogen peroxide, and an unrefined natural substance, such as a honey, that includes a substrate for the enzyme. In certain embodiments, the enzyme is a purified enzyme. In other embodiments, the substrate lacks catalase activity, and the enzyme is additional to any enzyme activity able to convert the substrate to release hydrogen peroxide that may be present in the unrefined natural substance. The storage-stable compositions do not include sufficient free water to allow the enzyme to convert the substrate. Use of the compositions to treat microbial infections and wounds is described, as well as methods for their production.
