  • Inhibition of angiogenesis
    Patent number: 6255353
    Abstract: Certain simple chemical agents, referred to herein as nitrone related therapeutics or “NRTs”, when administered to a patient susceptible to neovascularization (angiogenesis), can intervene and inhibit the disease's progress. Methods for therapeutically and prophylactically inhibiting angiogenesis by administering one or more NRTs are disclosed as are pharmaceutical compositions for use in such methods of treating. NRTs useful in these compositions and therapeutic methods are also disclosed.

  • Hydrophilic colored contact lens
    Patent number: 4963159
    Abstract: There is disclosed a method for making colored hydrophilic contact lenses. A contact lens constructed of hydrophilic polymer that is substantially devoid of the functional groups --COOH, --OH, --NH--R, wherein R is hydrogen or C.sub.1 to C.sub.8 alkyl, --NCO and epoxy is provided. At least a portion of the surface of the lens is coated with a color coat comprising at least one pigment, binding polymer having functional groups selected from at least one of --COOH, --OH, and --NH--R, wherein R is hydrogen or C.sub.1 to C.sub.8 alkyl, and an additional compound having at least two groups per molecule of --NCO. The coated lens is subjected to conditions which cause the color coat to adhere to the lens.
