Self-fueled particles for propulsion through flowing aqueous fluids

A simple, self-propelling particle system is disclosed that can deliver a cargo through flowing aqueous solutions. This disclosure provides a non-aqueous composition comprising: (i) particles formed of a carbonate salt and having an average diameter of about 100 μm or less; and (ii) an acid in solid form. The particles may be associated with a cargo molecule or particle. In mouse models of severe hemorrhage, the propelled particles are able to deliver a procoagulant enzyme and halt bleeding.

OXYGEN-GENERATING CRYOGELS

Disclosed are nanocomposite oxygen-generating cryogels and their uses in reducing hypoxia in a biological tissue, such as a tumor. Methods of treating cancer with the disclosed cryogels are also provided.

Dry composition comprising an extrusion enhancer
11103616 · 2021-08-31 · ·

Disclosed is a dry composition comprising one or more polyols, which upon addition of an aqueous medium forms a substantially homogenous paste suitable for use in haemostasis procedures. The paste reconstitutes spontaneously upon addition of the liquid; hence no mechanical mixing is required for said paste to form. The composition may further comprise an extrusion enhancer, such as albumin. Also disclosed are methods of preparing said dry composition, a paste obtained from said dry composition and uses of said dry composition or paste for medical and surgical purposes.

MATRIX BOUND NANOVESICLES AND THEIR USE

A composition is disclosed herein that includes isolated ECM-derived nanovesicles and a pharmaceutically acceptable carrier. Methods are producing the ECM-derived nanovesicles are also disclosed. These ECM-derived nanovesicles can be included in pharmaceutical compositions, bioscaffolds, and devices. Methods for using these ECM-derived nanovesicles are provided.

Silk sericin-based hydrogel, methods and uses thereof

The present disclosure relates to a novel sericin-based hydrogel wherein the silk sericin is enzymatically cross-linked for an improved treatment of wound healing, ischemic diseases or cardiovascular diseases, namely chronic wound healing, in particular diabetic wound.

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.

Method for producing a fibrin-based bioartificial, primarily acellular construct, and the construct itself

The invention relates to a method for producing a bioartificial and primarily acellular fibrin-based construct, wherein a mixture of cell-free compositions containing fibrinogen and thrombin is applied to a surface and subsequently pressurised.

INHIBITION OF CANDIDA AURIS BIOFILM FORMATION ON MEDICAL AND ENVIRONMENTAL SURFACES BY SILVER NANOPARTICLES

Materials, compositions, and methods of inhibiting biofilm formation and treating formed biofilm employing medically acceptable materials and silver nanoparticles coupled thereto are disclosed. Pathogenic fungi, bacteria, viruses, and combinations thereof are implicated in healthcare-associated infections with both significant medical consequences and high mortality rates. Substantially pure silver nanoparticles are coupled directly to polymer or textile medical dressings to treat fungal, bacterial, viral and combination infections.

SYSTEMS AND METHODS FOR TREATING AN ARTICLE INCLUDING A BIODEGRADABLE SUPERABSORBENT MATERIAL

A system for treating used hygienic articles including soiled or swollen superabsorbent materials (SAMs). The portion of the article including the soiled or swollen SAM is treated with a chemical which restructures or degrades the soiled or swollen SAM so that the products of the reaction are easily disposable in a method alternative to trash disposal and landfilling, including through municipal treatment where the products of the reaction do not clog a standard toilet or standard plumbing. Hygienic articles include baby diapers, adult diapers, incontinence pads, menstrual pads, or any other article which includes one or more SAMs.
