  • STEROL COMPOSITIONS AND METHODS OF MAKING SAME
    Publication number: 20070231447
    Abstract: The present invention provides compositions of sterol and monoglyceride, methods of making such compositions, and methods of making food products containing the compositions, such as beverages.

  • Low voltage differential swing (LVDS) signal driver circuit with low PVT sensitivity
    Patent number: 6788116
    Abstract: A low voltage differential swing (LVDS) signal driver having a constant output differential voltage (Vod) over variations in circuit fabrication processes, power supply voltages and operating temperatures (PVT). The minimum and maximum values of the LVDS output signal are monitored and, based upon the difference between them, a signal is provided to the circuit to control the LVDS output signal such that its peak-to-peak value is maintained at a determined value.

  • Delayed progression to aids by a missense allele of the CCR2 gene
    Patent number: 6600030
    Abstract: The present invention relates to a CCR2 deletion mutant, designated “CCR2-64I.” CCR2 is a C—C chemokine receptor and has been implicated as a co-receptor for HIV-1. It has been discovered that the presence of the CCR2-64I allele correlates with a postponement of AIDS outcomes, and that infected individuals who have the CCR2-64I allele are at a reduced risk for progression from HIV-1 infection to the development of clinical AIDS and death. Isolated nucleic acid molecule encoding CCR2-64I and the establishment of cell lines that express CCR2-64I provides valuable tools for continuing research on HIV infection. Diagnostic methods for analysis of the allelic frequency of CCR2 wild-type and 64I genes are provided. In addition, antibodies which bind to CCR2-64I, CCR2-64I variants, and CCR2 binding agents represent potential anti-HIV agents.
