  • Publication number: 20060122279
    Abstract: Lysine-spermine conjugates with a long-chain aliphatic (C12-C20) substituent at R1 bind and neutralize bacterial lipopolysaccharides. These compounds reduce lethality in a murine model of lipopolysaccharide-induced shock, and may serve as novel leads for developing novel anti-lipopolysaccharide agents for the therapy of Gram-negative sepsis. These compounds are represented by the formula: wherein X is O or H, H; R is a hydrophobic C12-C20 chain and Y is -NH2 or -H; and pharmaceutically acceptable salts thereof and prodrugs thereof.

  • Patent number: 7005050
    Abstract: The present invention relates to a novel, small-scale, electrophoretic separation system based on photodefined polymers and electrode-defined sample injection. Diffusion and displacement coefficients may be modified by varying the gel concentration, the intensity of the incident UV radiation and the temperature at which the gel is run. The device is an major advance over current technology since it provides for a significant reduction in size of the micro-electrophoresis apparatus and a significant cost savings.

  • Patent number: 6897670
    Abstract: A test apparatus (400) comprising a single handler (404) is coupled to a first tester (436) and second tester (408), wherein the first (436) and second (408) testers are coupled together. A first test procedure is performed on a set of second IC's using the first tester (436), simultaneously while a second test procedure is performed on a first set of IC's using the second tester (408). Sets of IC's may be tested in parallel by a plurality of testers (436/408) within a single handler (404). The first (436) and second (408) testers may be coupled to a multiplexer (460) to allow the use of a single test head (478), which avoids having to make contact to the integrated circuit more than once, which is particularly advantageous in wafer probe testing.
