  • Pectin Compositions and Methods of Use
    Publication number: 20240123113
    Abstract: The present disclosure describes bioadhesive polymer composition comprising: a first film comprising a polymer comprising: i) high-methoxyl pectin (HMP) and ii) an initial water content ranging from about 37% to about 43% (w/w); and a second film comprising a polymer comprising: i) HMP and ii) an initial water content ranging from about 9% to about 13% (w/w), wherein the first and second films are adhered to each other. Methods of preparing the bioadhesive polymer compositions and methods of sealing an ocular injury in an eye of a subject are also described.

  • Pectin-Carboxymethylcellulose Mesothelial Sealants and Protectants
    Publication number: 20230211042
    Abstract: This disclosure relates to pectin-based polymer compositions and methods of use thereof to cover, protect, and seal injuries, e.g., surgical wounds, in a mesothelial tissue. The methods include obtaining a bioadhesive pectin-based polymer composition including a complex of high-methoxyl pectin (HMP) and carboxymethylcellulose (CMC) in a ratio from about 10 to 1 to 1 to 10 by weight; applying the composition to an injured mesothelial tissue; and applying pressure for at least one minute to enable the composition to bind to the mesothelial tissue.
