Abstract: A vaccine, effective in inducing the production of antibodies with which to immunize a second subject passively against infection by Gram-negative bacteria and LPS-mediated pathology, comprises a non-covalent polyvalent complex formed between purified, detoxified LPS derived from E. coli and purified outer membrane protein derived from N. meningitidis. The same vaccine will also actively immunize a host subject against Gram-negative bacterial infections and LPS-mediated pathology. Meningococcal infections are included among those Gram-negative bacterial infections protected against by the vaccine.

Abstract: A stable form of artemisinin wherein an artelinic acid or artesunic acid is complexed with cyclodextrin analogs, preferably, ?-cyclodextrin. The complexed cyclodextrin artemisinin formulation shields the peroxide portion of the artemisinin backbone from hydrolytic decomposition rendering it stable in solution. Artelinic acid and cyclodextrin are placed into contact with one another to yield a 2:1 molecular species. Artesunic acid and cyclodextrin yield a 1:1 molecular species. The complexed cyclodextrin artemisinin formulation is effective for the treatment of malaria and is stable in solution for long periods of time.

Abstract: Novel burst-free, sustained release biocompatible and biodegrable microcapsules which can be programmed to release their active core for variable durations ranging from 1-100 days in an aqueous physiological environment. The microcapsules are comprised of a core of polypeptide or other biologically active agent encapsulated in a matrix of poly(lactide/glycolide) copolymer having a molar composition of lactide/glycolide from 90/10 to 40/60, which may contain a pharmaceutically-acceptable adjuvant, as a blend of uncapped free carboxyl end group and end-capped forms ranging to ratios from 100/0 to 1/99.

Abstract: Disclosed herein is a pharmacophore model for arthropod repellent activity and methods of making and using thereof. The pharmacophore comprises two hydrophobic aliphatic functions, one aromatic function and one hydrogen bond acceptor function. The pharmacophore model was made using a test set of arthropod repellent compounds. Also disclosed are arthropod repellent compounds identified by screening databases with the pharmacophore model. Also disclosed are methods of repelling arthropods from a surface or area. Compositions and formulations comprising the compounds of the present invention as well as objects having the compounds of the present invention are disclosed.
