  • Patent number: 9863911
    Abstract: A diagnostic Electrochemical Impedance Spectroscopy (EIS) procedure is applied to measure values of impedance-related parameters for one or more sensing electrodes. The parameters may include real impedance, imaginary impedance, impedance magnitude, and/or phase angle. The measured values of the impedance-related parameters are then used in performing sensor diagnostics, calculating a highly-reliable fused sensor glucose value based on signals from a plurality of redundant sensing electrodes, calibrating sensors, detecting interferents within close proximity of one or more sensing electrodes, and testing surface area characteristics of electroplated electrodes. Advantageously, impedance-related parameters can be defined that are substantially glucose-independent over specific ranges of frequencies. An Application Specific Integrated Circuit (ASIC) enables implementation of the EIS-based diagnostics, fusion algorithms, and other processes based on measurement of EIS-based parameters.

  • Publication number: 20050170445
    Abstract: Protein detection microarrays are used to specifically detect cytokines and growth factors that are associated with wound healing and with host organism responses to foreign, implanted materials (i.e., biocompatibility). Methods of establishing profiles that can be used in evaluating wound healing and biocompatibility take advantage of such cytokine- and growth factor-specific microarrays, which comprise anti-cytokine and anti-growth factor capture antibodies immobilized onto a solid substrate. The microarrays are produced using a printing buffer optimized for cytokine/growth factor detection. Methods of detecting the cytokines and growth factors also utilize optimized blocking buffers, fluorescent dyes, and immunoassay conditions. Sandwich and direct label fluoroimmunoassays can be carried out with the optimized microarrays.

  • Publication number: 20040247577
    Abstract: The present invention relates to methods of inhibiting heparanase activity and treating various conditions by administering to an animal an effective amount of an immunogen that elicits an immune response to heparanase. According to the present invention, the immunogen is heparanase or a fragment thereof and, preferably, the immunogen is an antigen presenting cell (APC), such as a dendritic cell (DC), displaying heparanase or a fragment thereof on the surface. The present invention also relates to compositions containing the immunogen.

  • Patent number: 6593394
    Abstract: A composition for use as a bioactive bone cement having a powder component including strontium-containing hydroxy apatite and formulated to create a settable fluid substance when mixed with a liquid component. The liquid component includes a Bisphenol A diglycidylether dimethacrylate resin which when mixed with the powder component creates a bioactive bone cement. The bioactive bone cement can alternatively be in the form of a two paste component system in which a first paste component including strontium-containing hydroxy apatite, Bisphenol A diglycidylether dimethacrylate resin and a polymerization initiator is formulated to create a settable paste substance when mixed with a second paste component. The second paste component includes strontium-containing hydroxy apatite, Bisphenol A diglycidylether dimethacrylate resin, and a polymerization accelerator which when mixed together with the first paste component creates a bioactive bone cement.
