Disulfides Patents (Class 424/707)
  • Patent number: 9222000
    Abstract: A method for coating a surface of a cell culture article includes dissolving a polymer having a covalently attached polypeptide in an aqueous solution to produce a polymer solution. The polymer is formed from monomers selected to form a polymer having a linear backbone, wherein the polymer is crosslink free. The weight percentage of the polypeptide relative to the polymer conjugated to the polypeptide is sufficiently high to render the polymer conjugated to the polypeptide water soluble. The aqueous solution is substantially free of organic solvents. The method further includes (i) disposing the polymer solution on the surface of the cell culture article to produce a coated article; and (ii) subjecting the coated article to sufficient heat or electromagnetic radiation to attach the polymer conjugated to a polypeptide to the surface of the cell culture article.

  • Patent number: 8992991
    Abstract: Degradable polymers were synthesized that self-assemble with DNA to form particles that are effective for gene delivery. Small changes to polymer synthesis conditions, particle formulation conditions, and polymer structure provides significant changes to efficacy in a cell-type dependent manner. Polymers presented here are more effective than commercially available materials, such as LIPOFECTAMINE 2000™, FUGENE®, or polyethylenimine (PEI), for gene delivery to cancerous fibroblasts or human primary fibroblasts. The presently disclosed materials may be useful for cancer therapeutics and regenerative medicine.

  • Patent number: 8361514
    Abstract: Alterations of redox homeostasis in mammals underlie a host of symptoms, syndromes and diseases, including AIDS and cancer, which can be successfully treated by administration to a mammal of therapeutically-effective amounts of sulfide compounds and/or thiosulfate compounds and/or thionite compounds and/or sulfite compounds and/or thionate compounds and/or any organic, inorganic or organometallic precursors thereof. The unique compositions of this invention contain one or more “active sulfur compounds” in combination with each other or with other therapeutic agents. The invention also encompasses the varying modes of administration of the therapeutic compounds. In particular, a novel method of combining active ingredient with wet cellulose is provided, which allows the wet cellulose to function as an enteric carrier.

  • Patent number: 5939478
    Abstract: The viscosity of a solvent is modified by thickening the solvent with a silicone latex. A silicone latex having a plurality of crosslinked polysiloxane particles is first prepared by mixing the siloxane polymer, a surfactant, and water; emulsifying the mixture to a gel phase; diluting the emulsion with water; adding a cure package (i.e., a catalyst, a crosslinker, or both, or a self catalytic crosslinker); and then without removing the water from the latex and after the particles of siloxane polymer in the latex have been cured, mixing the latex and solvent to thicken the solvent, forming viscous liquids, gels, and pastes. Water in the latex thickened solvent composition can be stabilized by adding a silicone polyether during mixing of the latex and the solvent.

  • Patent number: 5939079
    Abstract: The present invention relates to a process for the dispersion of at least one pulverulent organic filler and/or of at least one pulverulent inorganic filler in a vehicle composed of at least one fatty phase, by mixing the filler or fillers in the vehicle by high-pressure homogenization in one or a number of passes, to the cosmetic or dermatological compositions capable of being obtained by this process. The present invention also relates to the use of the compositions obtained by this process as the basis for care, make-up and/or hygiene products. The present invention also relates to the use of the compositions obtained by this process as the basis for products for protecting the skin, hair, scalp, nails, eyelashes, eyebrows and/or mucous membranes against the effects of ultraviolet radiation.

  • Patent number: 5888251
    Abstract: Hair upon the scalp or eyelashes are treated with hair coloring or mascara compositions in hair or eyelash coloring methods. The hair is typically colored with a mascara brush to achieve streaking and a non-homogenous coloring of the hair upon the scalp or the eyelash. A copaiba resin and a metal containing pigment are combined to obtain the hair coloring product. The resultant product is applied to the hair upon the scalp or the eyelash to effect coloring of the hair upon the scalp or the eyelash.
