  • Telomere length determination and applications
    Publication number: 20040234961
    Abstract: Methods for determining the telomere content in a sample, based on a ratio of telomeric DNA to total DNA or a subset of total DNA. Methods for determining the prognosis of a patient with cancer, including breast or prostate cancer, by determining the telomere content in a sample, the sample obtained from either tumor tissue or coexisting histologically normal tissue.
    Type: Application
    Filed: April 22, 2003
    Publication date: November 25, 2004
    Inventors: Colleen A. Fordyce, Jeffrey K. Griffith
  • Sensitive method for measurement of telomeric DNA content in human tissues
    Patent number: 5871926
    Abstract: A sensitive method for measurement of telomeric DNA content in human tissue, based upon the ratio of telomeric to centromeric DNA present in the tissue.
    Type: Grant
    Filed: April 21, 1997
    Date of Patent: February 16, 1999
    Assignee: The University of New Mexico
    Inventors: Jennifer E. Bryant, Kent G. Hutchings, Robert K. Moyzis, Jeffrey K. Griffith
  • Metal ion monitoring system
    Patent number: 5354996
    Abstract: A metal ion detection and quantification system in which the displacement of a radioactive isotope from a material that binds both the metal ion of interest and the radioactive isotope. The material in question binds the radioactive isotope with less force than the isotope of interest. The extent of release of the radioactive isotope is used to determine the concentration of the metal ion of interest. In one embodiment of the invention, the material used to bind the metal ion and radioactive ion is a protein of the metallothionein class of proteins.
    Type: Grant
    Filed: June 21, 1993

    Assignee: Permacharge Corporation
    Inventors: Jeffrey K. Griffith, Teresa A. Coons, Jack E. Floegel
  • Induction of antibiotic hypersensitivity in tetracycline-resistance microorganisms
    Patent number: 4911924
    Abstract: Microorganisms carrying tetracycline-resistant determinants are hypersensitized to Sm- and 2-DOS- aminoglycoside antibiotics by exposure to subinhibitory amounts of tetracycline inducer.
    Type: Grant
    Filed: April 17, 1987
    Date of Patent: March 27, 1990
    Assignee: University of New Mexico
