  • Patent number: 6365787
    Abstract: The present invention reveals the isolation, purification and characterization from the creosote bush Larrea tridentata of compounds of the structural formula: where R1, R2, R3 and R4 are each selected from the group consisting of HO—, CH3O— and CH3(C═O)O—, provided that R1, R2, R3 and R4 are not each HO—0 simultaneously. Each compound is a derivative of 1,4-bis-(3,4-dihydroxyphenyl)-2,3-dimethylbutane (nordihydroquaiaretic acid, NDGA). In addition, NDGA and each derivative can be used in a method to suppress Tat transactivation of a lentivirus, including the HIV virus, in a cell by administering NDGA or a derivative of NDGA to the cell.

  • Patent number: 6128015
    Abstract: Full-motion video data with a sub-picture and sound is recorded in a DVD-ROM drive. The DVD-ROM drive is connected to an ATAPI interface. Using a data buffer of the ATAPI interface, an MPEG stream is transferred to an MPEG2 decoder on the system board at a variable rate, and video data, audio data, and a sub-picture included in the MPEG stream are decoded by the MPEG2 decoder incorporated in the system. The decoded sub-picture is drawn in a VRAM as in normal VGA graphics. The sub-picture image drawn in the VRAM is synthesized with the video from the MPEG2 decoder by a multimedia display controller and displayed on a screen.

  • Patent number: 6114147
    Abstract: A method is provided for immobilizing a binding protein capable of binding to a specific compound, using recombinant DNA techniques for producing said binding protein or a functional part thereof. The binding protein is immobilized by producing it as part of a chimeric protein also comprising an anchoring part derivable from the C-terminal part of an anchoring protein, thereby ensuring that the binding protein is localized in or at the exterior of the cell wall of the host cell. Suitable anchoring proteins are yeast .alpha.-agglutinin, FLO1 (a protein associated with the flocculation phenotype in S. cerevisiae), the Major Cell Wall Protein of lower eukaryotes, and a proteinase of lactic acid bacteria. For secretion the chimeric protein can comprises a signal peptide including those of .alpha.-mating factor of yeast, .alpha.-agglutinin of yeast, invertase of Saccharomyces, inulinase of Kluyveromyces, .alpha.-amylase of Bacillus, and proteinase of lactic acid bacteria.

  • Patent number: 6090047
    Abstract: A novel method for estimating the end-systolic pressure-volume relationship (ESPVR) is presented. The method provides for accurate estimation of the ESPVR from a single beat of the cardiac cycle. The method is based on normalized human time varying elastance curves [E.sub.N (t.sub.N)]. The ESPVR is estimated from one beat using PV data measured at normalized time t.sub.N and end-systole (t.sub.max) to predict intercept: ##EQU1## and slope: E.sub.max(SB) =P(t.sub.max)/[V(t.sub.max)-V.sub.0(SB) ]. The present invention provides a method for ESPVR estimation which is non-invasive and particularly applicable for bedside applications.
