  • Publication number: 20240091413
    Abstract: Methods for viscosupplementation in a joint or surgical site of a human or animal subject are disclosed along with unique materials for achieving such beneficial outcomes. The methods generally comprise introducing into the joint or surgical site a plurality of porous viscoelastic solid hydrogel microparticles having a size of greater than about 30 pm, and substantially free of any cells, tissue, or therapeutic compounds. Kits for viscosupplementation in a joint or surgical site of a human or animal subject are also disclosed. The kits comprise the plurality of porous viscoelastic solid hydrogel microparticles having a size of greater than about 30 pm, and substantially free of any cells, tissue, or therapeutic compounds, and instructions for administering the same.

  • Publication number: 20220233454
    Abstract: Non-alginate hydrogel microparticles for localized delivery and sustained release of therapeutic cells and/or tissues (including homogenous or heterogenous cell clusters) at a site of implantation. The microparticles comprise a 3-dimensional matrix of covalently crosslinked non-alginate polymer compounds and a therapeutically-effective amount of cells and/or tissue entrapped therein, wherein the cells have a viability of at least about 50%, and wherein the microparticle has a size of greater than about 30 pm. Compositions containing such microparticles and methods of using such microparticles for treatment are also described.

  • Publication number: 20150140125
    Abstract: Synergistic cancer therapy drug combinations include therapeutically effective amounts of at least one chemotherapeutic drug or agent with a fortified decoction dosage form comprising from about 10 mg to about 6,000 mg each of ?-sitosterol, isovanillin, and linolenic acid. The decoction dosage preferably includes plant extract(s) of the genus Arum fortified with effective amounts of ?-sitosterol, isovanillin, and linolenic acid not derived from the plant. The combination may be in various forms including aqueous dispersions, gels, ampules, powders, capsules, pills, or tablets, and are normally administered orally to patients. The anticancer combinations have therapeutic effects on cancerous tissue which are greater than the sum of the individual therapeutic effects of the fortified decoction dosage form and the at least one chemotherapeutic agent on the cancerous tissue.

  • Patent number: 8895048
    Abstract: Substrates and devices for culturing cells are disclosed, along with methods of using the same. The substrates and devices include top surfaces with one or more divots disposed therein. Each divot is defined by an opening in the top surface, a rounded bottom surface spaced from the opening, and an interior side-wall surface extending between the rounded bottom surface and the opening. The top surface of the substrates and devices are optionally walled to form wells containing one or more divots. The substrates and devices may be used for reaggregating cells, for example, to form small islet cell clusters and for high throughput testing methodologies.
