Publication number: 20220091133Abstract: A method of immune phenotyping (evaluating adaptive and innate immune status) a subject is disclosed that includes providing a biological sample comprising diluted whole blood or isolated peripheral blood mononuclear cells (PBMCs), quantitating T cell interferon-gamma (IFN-?) and monocyte TNF-? production using ELISpot in the biological sample comprising diluted whole blood, and determining that the subject has an immunosuppressive immunological endotype if T cell interferon-gamma (IFN-?) and/or monocyte TNF-? production are decreased or low compared to a healthy subject. The disclosed method may be used to evaluating drug efficacy by measuring immune function in a subject after administering a drug to the subject to determine changes in the immune function of the subject in response to the drug.Type: ApplicationFiled: September 20, 2021Publication date: March 24, 2022Inventors: Richard Hotchkiss, Isaiah Turnbull, Monty Mazer, Kenneth Remy, Charles Caldwell, Lyle Moldawer, Scott Brakenridge

Patent number: 8168650Abstract: A series of N-substituted 9-azabicyclo[3.3.1]nonan-3?-yl phenylcarbamate analogs are disclosed, as well as methods of their preparation. Their affinities for sigma (?1 and ?2) receptors are described. Two new compounds, N-(9-(4-aminobutyl)-9-azabicyclo[3.3.1]nonan-3?-yl)-N?-(2-methoxy-5-methylphenyl)carbamate and N-(9-(6-aminohexyl)-9-azabicyclo[3.3.1]nonan-3?-yl)-N?-(2-methoxy-5-methylphenyl)carbamate, are shown to have a high affinity and selectivity for ?2 versus ?1 receptors. Among the disclosed compounds are biotinylated and fluorescent analogs. These compounds can serve as probes to the ?2 receptor. In addition, some disclosed compounds can induce apoptotic cell death by both caspase-dependent and caspase-independent mechanisms, and are effective for treatment of tumors. The compounds can be used as chemotherapeutics or chemosensitizers in the treatment of a wide variety of solid tumors.Type: GrantFiled: August 19, 2009Date of Patent: May 1, 2012Assignee: Washington UniversityInventors: Robert H. Mach, Richard Hotchkiss, William Hawkins, Rebecca Aft, Zhude Tu

Patent number: 8143222Abstract: Pharmaceutical compounds, pharmaceutical compositions and methods of treatment are disclosed, wherein a compound comprises a targeting moiety which, in free form, binds a cell receptor with a dissociation constant Kd of less than about 10?7 M, and a pharmaceutically active moiety, wherein the targeting moiety is other than an oligopeptide, a polypeptide, a peptidomimetic, a protein or a protein domain, and wherein the targeting moiety and the pharmaceutically active moiety are covalently attached. In some aspects, the targeting moiety binds a sigma-2 receptor with high affinity and high specificity, and the pharmaceutically active moiety is a pro-apoptotic peptide moiety. Methods of cancer treatment are disclosed comprising administering a disclosed pharmaceutical compound to a subject in need of thereof. The treatments selectively induce apoptosis in cancer cells. These methods can further comprise co-administration of radiation therapy and/or an additional chemotherapeutic agent.Type: GrantFiled: October 22, 2008Date of Patent: March 27, 2012Assignee: Washington UniversityInventors: Jonathan E. McDunn, William G. Hawkins, Robert H. Mach, Richard A. Hotchkiss

Patent number: 8107207Abstract: A potted electrical circuit is enclosed within a housing and has a first and second fiberglass layer that is laid upon a top surface of the potted electrical circuit. A lid of the housing seals the electrical circuit there within and an opening formed in a side wall allows circuitry wiring to extend there from out. The first fiberglass layer is a woven layer while the second fiberglass layer is a padding-like layer. Circuitry wiring pushes through the woven first fiberglass layer before extending out through the opening in the housing. The first fiberglass layer is tucked in and around the electrical circuit and adheres to the inside of the housing by attaching to the potting material while it hardens. In a preferred embodiment, the electrical circuit in combination with the insulation material is used within a transient voltage surge suppression device.Type: GrantFiled: August 8, 2008Date of Patent: January 31, 2012Assignee: Surge Suppression IncorporatedInventors: Ronald Hotchkiss, Richard Hotchkiss, Jr., Ricky Fussell, Andrea Haa
