  • Patent number: 6846842
    Abstract: A therapeutic composition comprising an alkyl, aralkyl, alkoxyalkyl or carboxyalkyl ester of 2-ketoalkanoic acid and a component for inducing and stabilizing the enol resonance form of the ester at physiological pH values is disclosed. The composition of the invention further comprises a pharmceutically acceptable carier vehicle in which the enol resonance form of the ester is stabilized at physiological pH values. Formulations containing the compositions of the invention permit the successful use of 2-ketoalkanoic acid esters, e.g., pyruvic acid esters, to treat, e.g., ischemic events, shock, organ reanimation, resuscitation and other recognized pyruvate-effective treatments. The compositions of the inventions are also useful in a process for preserving organ parts, organs or limbs removed from a living mammal and in need of preservation, e.g., for later transplantation to an organ recipient.

  • Patent number: 6610270
    Abstract: It is an object of the present invention to provide in vivo analytical methods that allow for diagnosis and management of therapy for diseases involving discrete biochemical pathways. In the method of the invention, a labelled tracer probe, a specifically designed substrate of a “gateway” enzyme, an enzyme marking a regulatory point in a discrete biochemical pathway, is administered to a subject; a labelled product of the action of the enzyme is measured; and the appearance and concentration of the product are related to the disease condition of interest. Determination of the rate of substrate-product conversion of the gateway enzyme allows for the analysis to be made. The method involves administering a defined amount of a labelled “metaprobe” substrate of the gateway enzyme to a subject, at a site that provides access to a desired pool of the gateway enzyme in the subject, and measuring the amount of the chosen labelled product.

  • Patent number: 4147840
    Abstract: Homotetra-alkyl substituted quaternary ammonium salts, or mixtures thereof which crystallize at 30.degree. C. or lower are included as an additive to the electrolyte of halogen cells. To maintain the salts as liquids, means for heating the additives to temperatures greater than 30.degree. C. are included in the cell. The additives form complexes with elemental chlorine, bromine, iodine, or mixtures thereof in the electrolyte which complexes comprise predominantly electrolyte insoluble liquids at temperatures in excess of 30.degree. C. The additives are characterized by rapid halogenation and dehalogenation while liquid; and thus, if maintained at temperatures in excess of 30.degree. C., are well suited for halogen storage in battery or fuel cell applications.

  • Patent number: 4104447
    Abstract: Alkyl or haloalkyl substituted quaternary ammonium salts having a nitrogen cation symmetry number no greater than three, or mixtures thereof, are added to the electrolyte of otherwise conventional halogen cells. The compounds form complexes with elemental chlorine, bromine, iodine, or mixtures thereof in the electrolyte which complexes, comprise predominantly electrolyte-insoluble liquids at the temperatures at which the cells are normally run, are characterized by rapid halogenation and dehalogenation, and thus are well suited for halogen storage in battery or fuel cell applications. The shelf-life and capacity of electrochemical systems containing an additive of the invention are improved.
