  • Publication number: 20200297856
    Abstract: The present invention relates to the unexpected discovery of compositions and methods for the treatment of growth plate defects. In certain embodiments, the methods prevent the growth of “bony bars” at the site of growth plate injury, thereby preventing growth arrest and/or deformity. In certain embodiments, the compositions comprise hydrogels comprising at least one biological factor capable of preventing bony bar formation.

  • Patent number: 10653783
    Abstract: Methods of producing microporous zwitterionic cryogels are described, wherein the cryogels are useful for sustaining release of therapeutic agents. The disclosed cryogels overcome several limitations associated with existing compositions, for example the disclosed cryogels have high loading efficiencies and a sustained release profile with minimal burst of up to 4 months or more. The characteristics of the disclosed cryogels can be varied by altering monomer (e.g. zwitterion) and crosslinker selection. The amount of monomer contained in the hydrogel may also be varied to aid in controlling the cryogel's chemistry.

  • Patent number: 7968842
    Abstract: The invention provides an interface assembly for delivering an ionized analyte from an ionization apparatus into an ion mobility spectrometer. This allows analysis of biological and non-biological samples, even non-volatile solids, via differential mobility spectrometry, without fragmentation of molecules. The invention also provides portable sample analysis systems that operate at ambient pressure. Systems of the invention may be used for high molecular weight species detection, for example, drinking water contaminants, pathogenic biological agents, bio-organic substances, non-biological material, peptides, proteins, oligonucleotides, polymers, bacteria, and hydrocarbons.
