  • Patent number: 6841345
    Abstract: The present inventors have found that certain preparations containing LPS and/or lipid A variants, derivatives, and/or analogs demonstrate non-pyrogenic properties and exhibit anti-viral activities. In particular, non-pyrogenic preparations of LPS, lipid A, LPS antagonists and lipid A antagonists, and derivatives thereof induce ? chemokine secretion, such as MIP-1?, but not proinflammatory cytokines, such as TNF?, IL-1? and IL-6. Non-pyrogenic preparations of the invention have been demonstrated by the Applicant to suppress HIV replication in human peripheral blood monocytes, as described by way of example herein. The present invention provides preparations of LPS or lipid A variants, analogs and derivatives of decreased or absent pyrogenicity which can be used as therapeutics for the treatment or prevention of immunodeficiency virus infection and its consequences.

  • Patent number: 6792075
    Abstract: An apparatus and method for mapping film thickness of one or more textured polycrystalline thin films. Multiple sample films of known thickness are provided. Each sample film is irradiated by x-ray at a measurement point to generate a diffraction image that captures a plurality of diffraction arcs. Texture information (i.e., pole densities) of the sample film, is calculated based on incomplete pole figures collected on the diffraction image and used to correct the x-ray diffraction intensities from such sample. The corrected diffraction intensities are integrated for each sample film, and then used for constructing a calibration curve that correlates diffraction intensities with respective known film thickness of the sample films. The film thickness of a textured polycrystalline thin film of unknown thickness can therefore be mapped on such calibration curve, using a corrected and integrated diffraction intensity obtained for such thin film of unknown thickness.
