The present disclosure relates to topical compositions for the treatment or prophylaxis of burns. The topical compositions comprise water, solvent, thickener, preservative and conditioning agent, and are exposed to gamma radiation. One embodiment of the topical compositions includes water, propanediol, sodium acryloyldimethyltaurate/VP crosspolymer, a combination of phenoxyethanol and caprylyl glycol and chlorphenesin, polyaminopropyl biguanide (PHMB) and a mineral complex. The present disclosure also relates to the use of the topical compositions with a dressing and the use of the topical compositions and dressings in treatment or prophylaxis of burns.

A method of treating a surface so that the antimicrobial activity of water-soluble antimicrobial agents is retained at the surface despite repeated washing with water is described. The method uses a dispersion of a lipidated polyanionic molecule and one or more antimicrobial agents in an aqueous carrier such as water. The treatment of the surface of the fabric of adhesive bandages and stainless steel is demonstrated using a combination of crystal violet and silver nitrate as the antimicrobial agents. The method has application in the treatment of such surfaces to control microbial growth and the development of biofilms.

Biocompatible polymer-coated transition metal chalcogenide (TMC) nanomaterials are provided herein. In particular, provided herein are two-dimensional polymer-coated TMC nanomaterials having excellent antimicrobial properties and biocompatibility, as well as methods of inhibiting microbiological growth on, or in, devices coated by or otherwise comprising the biocompatible polymer-coated transition metal chalcogenide (TMC) nanomaterials. In some cases, the biopolymer coating encapsulating the TMC nanomaterial comprises short synthetic single-stranded DNAs (ssDNAs). As described herein, ssDNA-encapsulated TMDCs exhibit no cytotoxicity against human cell lines at concentrations up to 0.25 mg/mL, but they exhibit exceptionally strong bactericidal activity against both gram-positive and gram-negative bacteria, including antibiotic-resistant Escherichia coli and a gram-positive methicillin-resistant Staphylococcus aureus (MRSA) strain. In other cases, TMDCs encapsulated by poly-L-lysine and Pluronic F77 display strong activity against multi drug resistance bacteria and form coatings that strongly inhibit bacterial biofilms, while TMDCs encapsulated by chitosan exhibit strong activity against fungi.

Disclosed are kits for preparing a reactive graft material and injecting the graft material into a patient. Kits may include a first syringe containing a first powdered component and a second syringe containing a second powdered component that is reactive with the first powdered component when the first and second powdered components are dispersed in a diluent solution. The kits may further include a vial sealed by a septum and containing the diluent solution. A syringe connector may be included that has a connector at each end configured to make a fluidic connection to, respectively, the first syringe and the second syringe, and also comprises a passageway adapted to allow fluid to pass between the syringes when the syringes are both fluidically connected to the syringe connector. A vial adapter comprising a connector adapted for fluidically connecting to at least one of the first syringe and the second syringe, a passageway adapted to allow fluid to pass from the vial into a syringe fluidically connected to the connector of the vial adapter, and a spike in fluidic communication with the passageway of the vial adapter may be included. The spike is adapted for piercing the septum of the vial. Certain kits also contain one or more needles for delivery of the graft material to a site within a body of a patient.

The invention relates to compositions including magnesium-lithium alloys containing various alloying elements suitable for medical implant devices. The devices may be constructed of the compositions or have applied thereto a coating formed therefrom. Within the structure of the magnesium-lithium alloy, there is a co-existence of alpha and beta phases. The invention also relates to methods of preparing the magnesium-lithium alloys and articles, such as medical implant devices, for use in medical applications, such as but not limited to, orthopedic, dental, craniofacial and cardiovascular surgery.

Formulations of cellulose nanofiber useful for osteoinduction are provided.

Disclosed herein is a method for forming an anti-microbial layer on an apparatus. Also disclosed is a method for improving the anti-bacterial properties of a titanium device coated with titanium-nitride (TiN). Also disclosed is a medical apparatus comprising an anti-microbial layer prepared by the disclosed methods. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

Provided herein are formulations containing copper ions and methods of treating underlying infections and conditions caused by coronavirus, particularly COVID-19, and influenzas, particularly influenza A and/or influenza B using such formulations. Methods of treating the underlying viruses and their resultant conditions using topical copper ion treatments are provided. A topical treatment in its basic form comprises a biocompatible copper ion solution or suspension obtained by leaching of the copper ions from copper metal. The copper ion solution or suspension may be combined with various carriers to form the copper ion treatment including creams or solutions. Methods of making the copper ion solution or suspension from solid copper metal in a biocompatible solution are also provided.

Systems and methods are provided for implementing machine learning techniques to distinguish a real identity, such as a set of identity information representing a real person, from a synthetic identity that may include portions of real identity information. Attributes regarding a target identity derived from a variety of retrieved data records may be provided as input to multiple machine learning models that generate scores associated with the potential of the target identity being synthetic. The scores may be combined and compared to a threshold to generate a determination of whether the target identity is a synthetic identity.
