  • Patent number: 6395290
    Abstract: Compositions and methods for repelling an animal from an area or object are described. The compositions include an animal repellent dissolved or dispersed in a polymer where the repellent is released from the polymer over a period of time in an amount effective to repel an animal from the area. Capture of the repellent in the polymeric matrix allows for concentration of the repellent in an easily movable or removable device. Moreover, the repellent is not diluted by contact with water. The composition is provided in a usable form as a film, a sheet, a shaped article, pellets, or microparticles. The method for repelling an animal from an area or object includes preparing a device incorporating the above compositions and placing the device in an area or near or on an object desired to be protected. The devices can be manufactured by solvent evaporation, solvent removal, coextrusion, spray drying, and hot melt encapsulation.

  • Patent number: 6355267
    Abstract: The present invention relates to a method of producing liposomes useful for encapsulating and delivering a wide variety of biologically active materials. The invention provides liposomes and a production method which is simple, feasible and inexpensive for the large-scale commercial manufacturing of liposomes and encapsulated materials. The method involves the formation of a liposome dispersion in the absence of an organic solvent or detergent, one or several cycles of freezing and thawing the liposomes, and dehydration of the liposome dispersion to form a lipid powder. When desired, the lipid powder is hydrated in the presence of the biologically active material whereby the material is encapsulated in reconstituted liposomes. The method can also include combining the liposome dispersion with a bulking agent prior to the dehydration and formation of the lipid powder. The addition of the bulking agent facilitates the handling of the lipid powder as well as its rapid dispersal upon hydration.

    Abstract: This invention relates to the treatment of diarrhea and related conditions caused by pathogenic E. coli infection. More specifically, this invention is drawn to the unexpected discovery that by administering a composition which binds and removes the shiga like toxins (SLT) produced by pathogenic E. coli whenever an antibiotic is administered, improved treatment is provided. Novel compositions containing both antibiotic and toxin binding composition and methods of treatment which use simultaneous administration toxin binding composition whenever antibiotic is administered are provided. These compositions and methods kill the enteric E. coli organisms which produce the conditions and neutralize the SLT produced by the organisms and/or released from the organisms when they are killed. Thus, these compositions and methods are better able to ameliorate the symptoms of the infection and inhibit progression of this infection into hemolytic uremic syndrome (HUS) than conventional treatment.

    Abstract: The present invention provides glycophospholipid and peptide-phospholipid conjugates comprising a phospholipid moiety and a saccharide or peptide moiety joined by an ether linkage comprising a secondary or tertiary amine. The conjugate structure of the invention comprises a flexible spacer arm between the phospholipid and saccharide or peptide moieties which, being variable in length, serves to optimize saccharide or peptide bioactivity. This invention further provides a method for the synthesis of such conjugates comprising the step of reductive amination. The method is efficient, economical and provides a high yield of product. Glycophospholipid and peptide-phospholipid conjugates of the invention can be incorporated and, optionally, chemically polymerized in self-assembling systems such as membranes, bilayers, films, liposomes and the like, and find utility diagnostically and therapeutically in medical and immuno-biological applications.

  • Patent number: 6149937
    Abstract: A process for the entrapment of amphiphilic compounds as uncharged or ionic with different mole ratios of phospholipid to the amphiphilic compound. Preparations of ionic species of amphiphilic compounds in the absence of crystals can be prepared, while preparations of uncharged amphiphilic compounds can be prepared with the compound exclusively entrapped inside the liposomes, or partly entrapped inside the liposomes with extraliposomal crystals.

  • Patent number: 6143280
    Abstract: There is provided a method of adhering dye to a silica. The method comprises providing a silica slurry which includes a plurality of silica particles, depositing alum in the pores of the silica particles, reacting a base with the alum to convert the alum into aluminum hydroxide resulting in treated silica particles. The treated silica particles are then filtered and washed. Thereafter, a dye is mixed with the treated silica particles. The resultant dyed silica product is resistant to dye migration.
