  • Patent number: 9226939
    Abstract: The invention relates to a method of inhibiting the cytotoxic activity of extracellular histones in a subject, comprising administering an effective amount of a polyanion to the subject. In particular the invention relates to a method for the treatment of patients who are suffering from sepsis and employs polyanions to rapidly form complexes with and thus neutralize or inhibit the cytotoxic activity of extracellular histone proteins, for example, those found in the blood circulation of sepsis patients.

  • Patent number: 8778300
    Abstract: A method of forming an injectable radioactive composition, the method comprising the steps of: (a) depositing a solid form of technetium onto a carbon crucible; (b) preheating the solid form of technetium to remove any carrier; (c) plasma ablating the technetium and portions of the carbon crucible; (d) allowing the carbon and technetium metal to co-condense from the gas phase to produce a nanoparticle composite aerosol in an inert gas; (e) dispersing the nanoparticle composite in water containing a low concentration of surfactant using an electrostatic precipitator; (f) size fractionating the nanoparticle dispersion by filtration with hydrophilic membranes of known pore size.

  • Publication number: 20090050049
    Abstract: A visual thermal history indicator comprising a pattern produced from at least two waxes wherein one wax has a melting point that differs from the other wax, or where the waxes have the same melting point but different melt flow behaviour, and wherein the pattern is adapted so that when the lower melting point wax melts or the wax with greater melt flow behaviour flows, the visual appearance of the pattern changes, and wherein when the second and subsequent higher melting waxes melt, or when the lower melt flow behaviour waxes flow, the visual appearance of the pattern changes as each wax melts or flows.
