ANTIMICROBIAL COMPOSITIONS
The invention provides antimicrobial compositions comprising charged cellulose nanofibrils dispersed in an aqueous solution having a dissolved oxygen content of at least 20 mg/L, preferably from 20 to 100 mg/L. The cellulose nanofibrils may have an increased surface charge due to their carboxylic acid content which contributes to their antimicrobial properties. In particular, the carboxylic acid content may be at least about 1000 μmol/g cellulose, preferably at least about 1400 μmol/g cellulose. The compositions are suitable for use in the treatment of wounds, in particular chronic wounds.
Hydrogen sulfide sustained releasing dressing and manufacturing method thereof
The invention is to provide a hydrogen sulfide sustained releasing dressing and a manufacturing method thereof. The hydrogen sulfide sustained releasing dressing includes a hydrocolloid, a surfactant and sodium hydro sulfide. The manufacturing method includes (a) heating and stirring a hydrocolloid material; (b) adding a surfactant and sodium hydrosulfide into the hydrocolloid material; and (c) injecting the hydrocolloid material containing the surfactant and the sodium hydrosulfide into a mold for thermoforming a hydrogen sulfide sustained releasing dressing.
CONSTITUENT FOR PREVENTING AND/OR TREATING SKIN WOUNDS
The invention provides a constituent that is used with a novel method for preventing and/or treating skin wounds and ensures stable delivery of low-concentration hydrogen sulfide to a wound site. The skin wound-preventing and/or treating constituent includes a sustained hydrogen sulfide releasing agent that is preferably a layered double hydroxide having HS— and/or Sk2- between layers where k is a positive integer.
Method for Treating Tissue
Methods for treating tissue are provided. In one embodiment, an adjunct material, when secured to tissue, can receive at least one physiological element released from the tissue during healing progression of the tissue, and can exhibit first and second stiffnesses in compression that are approximately constant during first and second time periods from contact with the tissue, with the second stiffness decreasing with time as a function of at least one of oxidation, enzyme-catalyzed hydrolysis, and change of pH resulting from interaction with the at least one physiological element. In another embodiment, the adjunct can receive a unit volume of fluid that causes first and second portions of the adjunct to expand according to first and second expansion behaviors that differ from one another to apply different pressures to the tissue.
PARTICULATE WATER-ABSORBENT RESIN COMPOSITION
Disclosed is a particulate water-absorbent resin composition containing at least one selected from the group consisting of a microporous inorganic material, silver, and a silver compound, and a polymer particle, in which the polymer particle contains an inorganic reducing agent.
GLASS COMPOSITION FOR WOUND CARE, WOUND COVERING MATERIAL, AND METHOD FOR PRODUCING SAME
Provided are: a glass composition for wound care, which promotes a wound healing process by providing a moist environment and nutrients necessary for growth of epidermal cells, and which has bactericidal properties for preventing critical fixing of bacteria to a wound surface and infection with bacteria; and a wound covering material that uses the glass composition. The glass composition contains, by mass % in terms of oxides, 5 to 70% of SiO.sub.2, 0 to 10% of Al.sub.2O.sub.3, 5 to 40.0% of B.sub.2O.sub.3, and 1 to 50% of CaO.
ANTIMICROBIAL AND ANTIVIRAL HYGIENIC PRODUCTS
The present invention relates to hygienic products such as sanitary pads and tampons, patient/adult diapers and baby diapers which are made antimicrobial. In the present invention, a mixture of glucopon, chlorhexidine gluconate and triclosan is obtained from the boron compounds called sodium borate, zinc borate, sodium perborate tetrahydrate, borax pentahydrate and disodium octaborate tetrahydrate; and this mixture provides antifungal, anticandidal, antibacterial and antiviral properties to the woven or non-woven textile products and hygienic products. Additionally, the said hygienic products are made hydrophilic by means of the invention.
Mesoporous bioactive glasses and uses thereof
The present disclosure relates to mesoporous glasses as well as uses of such glasses, for example, as hemostats.
Method and composition of humidity-controlled generation of chlorine dioxide in polymers and superabsorbent hydrogels
A composition and method for chlorine dioxide production through reaction-diffusion chemistry that facilitates the in situ generation of chlorine dioxide, wherein a dry solid composition of hydroxymethanesulfinic acid monosodium salt dihydrate (abbreviated HMS) and a chlorine dioxide precursor are activated via the addition or absorption of water to produce chlorine dioxide. The dry solid chemical composition comprises dry, safe, transportable reagents that integrate with polymeric materials such as packaging and superabsorbent and stimuli-responsive hydrogel polymers to combine with water to produce chlorine dioxide.
BIOACTIVATABLE DEVICES AND RELATED METHODS
The present disclosure is related to inorganic, biocompatible material compositions for bioactivatable devices, devices, and products comprising transition metal chalcogenides, such as molybdenum sulfides, that can be converted in vivo from a non-bioactive state to a bioactive state upon exposure to physiological conditions, wherein the bioactivated transition metal chalcogenide derivatives, such as molybdenum sulfide derivatives, exhibit copper-chelating activities. Various methods for the application of these compositions for enhancing biocompatibility and reducing or modulating copper-dependent biological reactions are provided.
