  • Patent number: 11839626
    Abstract: Antimicrobial polymer coating formulations are prepared that protect biological surfaces by treating, reducing, ameliorating, preventing or inhibiting pathogenic microorganism ingress to a human or animal host, reducing the potential for infection, particularly by necrotizing fasciitis originating microorganisms, through use of a polymer coating barrier containing antimicrobial agents that facilitates sustained release of biocidal agents active against such opportunistic microorganisms. Such formulations are effective for inhibiting microbial ingress pertaining to soft tissue and skin tears, abrasions, punctures and surgical wounds, and can be used as in water environments and as a skin protectant sunscreen and insect repellent.
    Type: Grant
    Filed: September 1, 2017
    Date of Patent: December 12, 2023
    Assignee: ROCHAL TECHNOLOGIES LLC
    Inventors: Joseph Charles Salamone, Katelyn Elizabeth Reilly, Ronald Thomas Nixon, Ann Beal Salamone, Kelly Xiaoyu-Chen Leung
  • Patent number: 11590259
    Abstract: This invention relates generally to water-insoluble but water-swellable and deformable crosslinked PEGylated microgel particles of proteins and protein-based macromolecules that are pseudoplastic (shear thinning) and flow in aqueous media under shear and which can be injected or made to flow, wherein said microgel particles can reform as a cluster of microgel particles when shearing forces are removed. The microgel particles function as a matrix to support cell growth, viability, and proliferation.
    Type: Grant

  • Patent number: 10688159
    Abstract: A treatment for pruritus is described that is based upon amylase. The amylases (?-, ?-, ?-amylase) are noted for the cleavage of the ?-glycosidic bonds of polysaccharides, yielding lower molecular weight carbohydrate/sugar fragments. It has now been found that ?-amylase is effective in the reduction of pruritus (itching) of affected tissue.

  • Patent number: 10238719
    Abstract: A debridement enzyme for necrotic tissue is described that is not dependent upon proteolytic enzymatic activity but instead utilizes the amylase family of enzymes. The amylases (?-, ?-, ?-amylase) are noted for the cleavage of the ?-glycosidic bonds of polysaccharides, yielding lower molecular weight carbohydrate/sugar fragments. It has now been found that ?-amylase is effective in the debridement of devitalized tissue.
