  • Two phase bioactive formulations of bis-quaternary pyridinium oxime sulfonate salts
    Patent number: 8722706
    Abstract: The present invention relates to two phase systems of a bioactive ingredient in particle form that has limited or no solubility in a liquid medium, which provides stability to the bioactive ingredient that is similar to the bioactive ingredient when in the solid state. The bioactive ingredient may be capable of therapeutically treating for the presence of a cholinesterase inhibitor. The bio active ingredient comprises 1,1?-methlyenebis[4-[(hydroxyimino)methyl]-pyridinium]dimethanesulfonate.
    Type: Grant
    Filed: August 15, 2008
    Date of Patent: May 13, 2014
    Assignee: Southwest Research Institute
    Inventors: Hong Dixon, Joseph A McDonough, Larry Allen Cabell, Patricia Underwood
  • Bis-quaternary pyridinium-aldoxime salts and treatment of exposure to cholinesterase inhibitors
    Patent number: 8404850
    Abstract: Bis-quaternary pyridinium-aldoxime salts are disclosed, and their associated polymorphic character, along with their methods of preparation. Such polymorphic salts may then be used for treatment of exposure to cholinesterase inhibitors, such as a phosphorous containing cholinesterase inhibitor type compound.

  • Modified calcium phosphate nanoparticle formation
    Patent number: 8309134
    Abstract: The present disclosure relates to non-aggregating nanoparticles and their associated methods of preparation. The nanoparticles may have a surface and a size range of 1 nm to 999 nm, along with a zeta potential of ?50 to 50 millivolts. A polycation and/or polyanion may be disposed on the nanoparticle surface. In addition, an active ingredient may be encapsulated within the nanoparticles or associated with the polycation or polyanion on the nanoparticle surface.

  • Colorimetric and fluorimetric analysis of carbohydrates
    Patent number: 6534316
    Abstract: Methods are disclosed for the simple, rapid, and selective colorimetric detection of carbohydrates, including fructose, glucose, sialic acid, and oligosaccharides. There is no need for any prior hydrolysis or other chemical modification or of the analytes. Resorcinarenes, xanthene dyes, and related compounds, formally produced by the reaction of 2 equivalents of resorcinol and a suitable electrophilic condensation partner, are used as chromophores or fluorophores for the detection of sugars and other carbohydrates.
