  • Patent number: 6641815
    Abstract: In this application is described the expression cloning and functional characterization of the CD36-binding domain of Sequestrin. Sequestrin is a surface protein of 215-250 kD size which does not vary in size between parasite strains. The Sequestrin gene appears to be single-copy-number within the genome; noncytoadherent laboratory parasite strains carry the sequestrin gene but fail to express the protein. Sequestrin binds with high affinity to CD36. Sequestrin protein and sequence can be used as a diagnostic, prognostic, and therapeutic tool.

  • Patent number: 5753238
    Abstract: The present invention relates novel methods and compositions for blocking transmission of Plasmodium spp. which cause malaria. In particular, P28 proteins are disclosed which, when administered to a susceptible organism, induce an immune response against a 28 kD protein on the surface of Plasmodium ookinetes and block transmission of malaria.

  • Patent number: 4494533
    Abstract: A traction device for providing relief to the spinal column in which a person is suspended from the midsection over a pair of support pads. The angular position of each support pad is independently adjustable, thereby enabling the stretching effect of the traction device to be specifically tailored for the particular injury being treated. A control mechanism for adjusting and locking the angular position of each pad, and a pad with a generally saddle-shaped profile is described.
