  • Patent number: 7807179
    Abstract: The present invention relates to hyperproliferative diseases. Specifically, the present invention encompasses pharmaceutical compositions comprising a modified Reoviridae virus, wherein the Reoviridae virus is conjugated to a hydroxylated hydrocarbon or a polycationic polymer to reduce the clearance of the composition and reduce the immunogenicity of the composition. Yet further, the invention relates to methods of treating a hyperproliferative disease by administering to a patient an effective amount of the modified Reoviridae virus.
    Type: Grant
    Filed: April 27, 2007
    Date of Patent: October 5, 2010
    Assignee: Board of Regents, The University of Texas System
    Inventors: Jeffrey Tarrand, Xiang-Yang Han

  • Publication number: 20050130168
    Abstract: The present invention provides a rapid and precise test for objectively determining a bacterium species. The assay is applicable to sample isolated from blood, serum, other bodily fluids or environmental samples. The detection method comprises the steps of annealing a region in a DNA template to a specific oligonucleotide primer set comprising SEQ-FOR and SEQ-REV in a complimentary fashion, said primer set designed to give rise to a PCR product having a predetermined size dictated by a complimentary primer set; amplifying said region of DNA template by performing a polymerase chain reaction to produce said PCR product; determining a nucleatide sequence of said PCR product; and comparing said PCR product to a DNA sequence in a database to determine a species of bacterium.

  • Publication number: 20050048509
    Abstract: The present invention provides methods for detecting the presence of invasive pathogenic molds in biological samples that are based on amplification of mold nucleic acids. The methods may further comprise quantitating and real time detection of the invasive mold. The methods of the invention are highly specific and do not co-amplify human or other yeast nucleic acids. The methods of the invention are also extremely sensitive. Thus, methods for diagnosing infections caused by invasive mold are provided. The invention also provides kits for detection of invasive molds.
