  • Publication number: 20080076122
    Abstract: A method of characterizing exposure to ionizing radiation, utilizing the steps of selecting a set of biomarker geness for characterizing exposure to ionizing radiation, and using the set of biomarker genes for characterizing exposure to ionizing radiation. The step of selecting a set of biomarker genes for characterizing exposure to ionizing radiation was developed utilizing a unique set of 420 oligonucleotide probes for human genes capable of discerning past exposure to different doses of ionizing radiation. The step of selecting a set of biomarker genes for characterizing exposure to ionizing radiation utilizes groupings of genes that represent candidate panels of mRNA biomarkers.

  • Patent number: 4156494
    Abstract: Disclosed is a housing providing a cylindrical chamber vertically oriented, which accommodates a mass of randomly entwined coil springs. An impact member is rotated within the member closely adjacent the bottom end wall of the chamber. As the mass of springs is moved in the chamber by the impact member, individual springs disengaged from the mass by impact move through a discharge opening adjacent the top of the curved side wall of the chamber and through a tangential discharge chute to automatic assembly apparatus or the like.
