  • Patent number: 5968741
    Abstract: The present invention provides serological and genetic methods of diagnosing a medically resistant clinical subtype of ulcerative colitis UC. The present invention provides a method of diagnosing a medically resistant clinical subtype of UC by determining the presence or absence of anti-Saccharomyces cerevisiae antibodies (ASCA) in a patient with UC, where the presence of ASCA indicates the medically resistant clinical subtype of UC. The present invention also provides a method of diagnosing a medically resistant clinical subtype of UC by determining the presence or absence of a TNFa2b1c2d4e1 haplotype in a patient with UC, where the presence of said TNFa2b1c2d4e1 haplotype indicates the medically resistant clinical subtype of UC.

  • Patent number: 5968515
    Abstract: The invention comprises a low temperature method for the in situ derivatization and coupling of thermally and hydrolytically labile organic compounds such as spectinomycin to immunogenic carrier substances. The compound coupled to the immunogenic carrier is utilized to produce antibodies selective for the organic compound. Such methods allow for the quantitative analysis of the target organic compound and may be competitive or non-competitive immunoassays in which the dose response is directly or indirectly proportional to the concentration of spectinomycin-related substances. Such assays may be used to detect the presence of or to quantitate the amount of the organic compound in a complex and varied immunological background such as a sample of a biomass material. Detection of organic compound in the sample occurs through binding to a specific antibody.

  • Patent number: 5962238
    Abstract: A method and an apparatus for analyzing a material within a container, such as blood within a capillary in a volumetric cytometry system provides for detecting the edges of the container, counting the cells within the container, characterizing the cells within the container, and evaluating channels of data which contain information relevant to more than one of the detectable characteristics of the cells. A scanner scans a container of material including certain cells. Sampling circuitry is coupled to the scanner to generate scanned images of the material in the container. Two or more scanned images are generated based on fluorescence data from dyes that have overlapping spectra. The two scanned images are processed using a linear regression analysis among corresponding pixels in the scanned images near certain cells to characterize relative contents of two fluorescing dyes in a target cell.

  • Patent number: 5958676
    Abstract: A diagnostic assay for detecting the presence of an infectious herpesvirus in a specimen and a genetically engineered cell line for use in such assay are disclosed. The cell line used in the assay expresses a reporter gene only if infectious herpesvirus is present in the specimen. The assay involves inoculating a DNA-transfected cell line with a specimen suspected of containing a herpesvirus, allowing a sufficient period of time for the herpesvirus infectious cycle to proceed, and detecting and quantifying the number of herpesvirus-infected cells to determine the number of infectious herpesvirus virions in the specimen. The cell line is a DNA-transfected cell line susceptible to infection by a herpesvirus which is stably transformed with a chimeric gene comprising a herpesvirus inducible promoter and a gene coding for an enzyme, the expression of the enzyme being dependent upon and quantitatively proportional to the presence of herpesvirus. A kit for such assay is also provided.

  • Patent number: 5942075
    Abstract: A plasma processing apparatus includes a processing vessel for accommodating an object to be processed, a processing supplying mechanism for supplying processing gas into the processing vessel, first and second electrodes arranged to oppose each other in the processing vessel, and high-frequency power supply for supplying a high-frequency power to at least one of the first and second electrodes. The apparatus forms a plasma of the processing gas by using discharge occurring between the first and second electrodes due to the high-frequency power and performs a plasma process for the object by using the plasma. The surface of a solid except for the object to be processed in the processing vessel has a corner portion and a portion other than the corner portion, and the solid surface has a shape by which the thickness of a sheath formed between the solid surface and the plasma is nearly uniform in the corner portion and the other portion.
