Nanocomposite ionic-covalent entanglement reinforcement mechanism and hydrogel
A biodegradable and biocompatible three dimensional construct comprising a combination of a nano silicate (e.g., laponite) and two different polymers, the two polymers each individually providing at least one covalently linked polymer chain and at least one ionically linked polymer chain, the polymeric chains forming a dual strengthening intertwined polymeric system. The constructs demonstrate improved mechanical and strength properties, while the bioinks provide a material having superior printability characteristics suitable for printing a three dimensional biodegradable construct having an aspect ratio of greater than 2.0. The bioink may also comprise cells or combinations of cells. Methods of using the constructs and bioinks for wound healing preparations and tissue regeneration are also provided.
BIOADHESIVE COMPOSITION COMPRISING MUSSEL ADHESIVE PROTEIN AND PREPARATION METHOD THEREOF
The present disclosure relates to a bioadhesive composition including mussel adhesive protein; and at least one of polyacrylic acid and polymethacrylic acid; in which the mussel adhesive protein is linked to the at least one of polyacrylic acid and polymethacrylic acid by an amide bond and has a three-dimensional network structure and a method for preparing the same.
HOT MELT PROCESSABLE (METH)ACRYLATE-BASED MEDICAL ADHESIVES
Adhesive articles include a substrate; and a hot melt processable pressure sensitive adhesive on the substrate. The hot melt processable pressure sensitive adhesive is a (meth)acrylate-based copolymer that is the reaction product of a reaction mixture that is free of acidic or basic monomers, and includes an alkyl (meth)acrylate, a hydroxyl-functional (meth)acrylate, and a photocrosslinker. The (meth)acrylate-based polymer is prepared in a thermoplastic package.
SKIN COMPOSITION
It is an object of the present invention to provide a film-forming composition for skin (such as a film-type skin protectant or a film-type skin topical agent) that does not contain a lower monohydric alcohol such as ethanol or isopropanol, is excellent in quick-drying properties and water resistance, is less sticky, and is excellent in feeling of use. The present invention relates to a film-forming composition for skin which contains a specific acrylic polymer, a plasticizer and water and is substantially free of a lower monohydric alcohol such as ethanol or isopropanol. The composition of the present invention is extremely useful for treatment of chronic skin diseases (that is, skin diseases in which skin barrier function is deteriorated) represented by hand eczema, atopic dermatitis, and the like.
IN-SITU CROSS-LINKABLE POLYMERIC COMPOSITIONS AND METHODS THEREOF
A biocompatible polymeric composition for cross-linking in-situ in a wound is disclosed comprising 1) one or more polyanionic polymers such as alginates or hyaluronates, able to be cross-linked the surface of the wound and 2) one or more polycationic polymers such as chitosan or DEAE-Dextran, that assists in the solidification process as well as speeds up hemostasis without the need for applying pressure. The biocompatible polymeric composition may further comprise a cross-linking agent such as aqueous calcium chloride. The invention encompasses an initial polymeric composition, the solidified matrix cross-linked and integrated at the wound site, including the methods of using, applying, and cross-linking the composition.
Polymer particles
Biodegradable, cross-linked polymer particle embolics and methods of making the same are described. The particle embolics can be used as embolization agents.

Use of seaprose to remove bacterial biofilm
A method of disrupting a bacterial biofilm present on a surface, comprising applying a composition that includes a semi-alkaline protease produced by the fermentation of the fungus Aspergillus melleus (Seaprose) to the bacterial biofilm, wherein application of the composition to the bacterial biofilm disrupts the matrix of the bacterial biofilm.

APPARATUSES AND METHODS FOR IMPROVING POST-OPERATIVE RECOVERY FROM SURGERY
This disclosure relates to apparatuses and methods for preventing the onset and progression of POI. In one example, a fan-like polyurethane heat-sealed bilayer that surrounds a plurality of wedge-shaped foam strips that join at a collecting foam portion, is subjected to negative pressure provided through silicone tubing which is sealed to the perforated collecting foam portion. Such negative pressure applied for approximately 48 to 72 hours after closure of the abdomen, helps prevent POI which in turn enhances patient recovery, and reduces the length of their hospital stay.
