  • Patent number: 11723860
    Abstract: A biocompatible antimicrobial composition effective against microbial biofilms, including in vivo biofilms containing gram-positive bacteria, can be delivered to and used near the spinal column of vertebrates. Once introduced to an area colonized with a bacterial biofilm, particularly an intervertebral disc, the antimicrobial composition weakens the EPS/ECPS macromolecules of the biofilm, which makes the entire biofilm structure susceptible to being dislodged from the affected area or biosorbed. Additionally or alternatively, certain of the subcomponents of the solute component, as well as perhaps the organic liquid(s) of the solvent component, might lyse microbes, particularly gram-positive bacteria, previously protected by the EPS/ECPS macromolecules. Swelling of and around previously impacted intervertebral discs can be reduced or eliminated, often resulting in appreciable reductions in patient pain levels.

  • Patent number: 9414967
    Abstract: A thin chitosan-based material can be used for biomedical applications. The chitosan has been treated in a nitrogen field by applying energy to ionize nitrogen in and around the chitosan material. A single or multiple such treatments may be employed. For example, the chitosan material may be irradiated under nitrogen using ?-irradiation, treated under a nitrogen plasma, or both. A thin chitosan material can be readily treated by surface modifying treatments such as irradiating under nitrogen using ?-irradiation, treating under a nitrogen plasma, or both.

  • Patent number: 9410052
    Abstract: Aqueous binder compositions with reduced rates of salt precipitation are described. The compositions may include a carbohydrate and a sequestrant for sequestering one or more multivalent ions (e.g., Ca2+, Mg2+, Ba2+, Al3+, Fe2+, Fe3+, etc.). The sequestrant reduces a precipitation rate for the multivalent ions from the aqueous binder composition. Methods of reducing salt precipitation from a binder composition are also described. The methods may include the steps of providing an aqueous binder solution having one or more carbohydrates. They may also include adding a sequestrant for one or more multivalent ions to the aqueous binder solution. The sequestrant reduces a precipitation rate for the multivalent ions from the binder composition.

  • Patent number: 9404076
    Abstract: A dry yeast composition which includes 5-adenosyl-L-methionine and a thickener and has excellent storage stability. A thickener is added to a yeast cell concentrate obtained by culturing yeast which has SAMe-producing ability and collecting the cells, and the resultant mixture is dried. Thus, a dry yeast containing a high concentration of 5-adenosyl-L-methionine which has excellent storage stability and excellent bioabsorbability can be easily and profitably produced. It is hence possible to supply a market with a dry yeast composition that contains a high concentration of 5-adenosyl-L-methionine, which is useful as a water-soluble physiologically active substance, and that has excellent storage stability and bioabsorbability.

  • Patent number: 9248079
    Abstract: The method for cleaning dental plaque biofilm from the teeth includes the steps of applying a liquid gellable composition to the teeth, the composition including a positively charged polymer such as chitosan, the liquid composition having a viscosity which results in coverage of substantially all of the exposed areas of the teeth. The liquid composition is then gelled by the addition of a second composition, such as a negatively charged compound. The resulting gelled composition has an adherence to the plaque biofilm which is greater than the adherence between the biofilm and the teeth. The gel layer with the biofilm is peeled off of the teeth, removing the dental plaque.

  • Publication number: 20150135644
    Abstract: A wound dressing comprising acylated chitosan fibre. The dressing has a wet strength of 0.3 N/cm or above. The acylated chitosan fibre may have a degree of substitution of 0.10-0.50. The acylated chitosan fibre may preferably have a degree of substitution of 0.20-0.40. The dressing may have an absorbency of 5-25 g/g of a solution containing 8.298 g/l of sodium chloride and 0.368 g/l of calcium chloride dehydrate as measured by BSEN 13726-12002 Part 1 Aspects of Absorbency. The base material of the dressing may be chitosan fibre that has been chemically modified through an acylation process using anhydride and ethanol as the solvent. A method of manufacturing the wound dressing involves reacting chitosan fibre with anhydride and making acylated chitosan felt through a nonwoven process, and through cutting, packing and sterilizing processes.
