  • Patent number: 6638959
    Abstract: Microbiological control is achieved by continuously and inexpensively dosing water in contact with biofilm, or that comes into contact with biofilm, using a highly effective biocide that provides very effective microbiocidal control of planktonic microorganisms and of biofilm species, even where the biofilm infestations have been in existence for long periods of time and thus have encased themselves in a substantial quantity of slimy defensive polysaccharide layers or films. In addition, the biocide used makes possible significant reduction in copper and/or iron surfaces in contact with the water as compared to N,N′-bromochloro-5,5-dimethyl hydantoin. Still other advantages are made possible by the described technology.

  • Patent number: 6416775
    Abstract: This invention relates to certain natural diatomaceous earth granule compositions which can be broadcast, i.e., dry spread on the soil to deliver a pesticide or fertilizer. The granules retain their physical integrity when spread, and have the unique property to spontaneously disintegrate when irrigation water is applied or rainfall hits the particle. Upon wetting, the particle disintegrates (blooms) to cover the soil surface. This bloom can cover an area many times the original area covered by the granule. The granules have high loadings of the diatomaceous earth, i.e. from about 35 to about 95 weight percent and contain from about 5 to about 40 weight percent of a surfactant system which exhibits excellent disintegration; rewetting and binding properties. Bioactive compounds can be loaded at up to 60 weight percent of the granule. Bioactive compounds may be formulated products or technical grades and may be homogeneously distributed throughout the granule or spray impregnated onto the granule.

  • Patent number: 6306415
    Abstract: A topical insect repellent with extended duration of protection was obtained from mixtures of molecules based on two or more volatile repellent organic molecular species occurring naturally on the human skin surface. The novel repellent comprises mixtures of lower, intermediate, and higher volatility organic molecules. Active ingredients for formulations are obtained from homologous series of carboxylic acids, alcohols, ketones, and lactones which span a similar range of volatility and which occur naturally on the skin surface. Volatile silicone fluid imparts mildness and water repellency to the repellent formulations. The new natural repellent exhibits the longevity and repellency that is comparable to N,N-diethyl-m-toluamide (DEET), a synthetic compound employed in almost all commercial formulations, but the inventive natural repellent is more acceptable than DEET, which has an unpleasant odor and imparts a greasy feel to the skin.

  • Patent number: 6210700
    Abstract: An improved immunomodulatory therapy for enhancement of depressed host defense mechanisms and improving allograft survival rates comprising the use of omega-9 unsaturated fatty acids to alter the immune response associated with organ transplantation. It is administered optionally in conjunction with an immunomodulatory diet comprising arginine and its salts, or metabolic precursors of arginine, together with an immuno-suppressive treatment comprising the administration of cyclosporine or other immuno-suppressants and optionally, with or without a donor specific transfusion. An especially preferred source of the omega-9 unsaturated fatty acids is canola oil.

  • Patent number: 6117419
    Abstract: Described herein is a method for making a flake for use in a topical application. The flake is formed by contacting a liquid phase waxy material that may contain pigments, fragrance, plasticizer, hydrophilic modifier with a pseudoplastic hydrophilic gel, and/or an active ingredient. The waxy material contacts the surface of the gel and after the two materials have contacted, the waxy material is solidified and forms a sheet. This sheet is then broken into pieces to form the flakes of the present invention. The flakes can be used in formulating any topical product that can contain a lipid material.

  • Patent number: 6077714
    Abstract: The invention provides a method for making a selenium-carrier conjugate by covalently attaching (i) an organic selenium compound selected from the group consisting of RSeH, RSeR, RSeR', RSeSeR and RSeSeR', wherein R and R' are each an aliphatic residue containing at least one reactive group selected from the group consisting of aldehyde, amino, alcoholic, carboxylic, phosphate, sulfate, halogen or phenolic reactive groups and combinations thereof, to (ii) a carrier having a constituent capable of forming a covalent bond with said reactive groups of said selenium compound to produce a selenium-carrier conjugate which is capable of specific attachment to a target site. The carrier may be a protein, such as an antibody specific to a bacteria, virus, protozoa, or cell antigen, including without limitation, cell surface antigens, a peptide, carbohydrate, lipid, vitamin, drug, lectin, plasmid, liposome, nucleic acid or a non-metallic implantable device, such as an intraocular implant or a vascular shunt.

  • Patent number: RE37890
    Abstract: Controlled release compositions of matter are disclosed comprising complexes for treating a population of one or more aquatic organisms in a column of water. The complexes comprise at least one system wherein the system comprises at least one bioactive agent as a component selected for treating a population of aquatic organisms, at least one carrier component, and at least one coating component for regulating the controlled release rate and release profile of the bioactive agent in water or at least one bioactive agent and one joint-function component that can serve as both a carrier and coating to regulate the controlled release rate and release profile of the bioactive agent in water, with or without optional binder components and/or additional formulation materials. The components are selected to sink or float so that the complexes will permeate and/or remain in any planar or volumetric segment of a water column for a period of time that is sufficient to effectively treat a population of aquatic organisms.
