  • Publication number: 20080175893
    Abstract: The present invention provides gas-containing liposomes. In particular, the present invention provide methods of generating gas-containing liposomes where the gas is introduced under pressure, as well as gas-containing liposomes which contain a large volume of gas (e.g., 10 ul of gas per 5 mg of gas-containing liposomes). In certain embodiments, the gas-containing liposomes contain nitric oxide gas. In some embodiments, such nitric oxide containing liposomes are used to treat a medical condition that is treatable by nitric oxide gas (e.g., intimal hyperplasia).

  • Publication number: 20070042126
    Abstract: The invention is a coating and a method for applying coatings to fiber reinforced composite materials. A first polymeric layer, free of fibers and particulate, coats a fiber reinforced polymer substrate. The first layer joins the fiber reinforced polymer substrate to a second polymeric layer. The second polymeric layer contains a polymeric matrix and a particulate within the polymeric matrix. Finally, at least one thermally sprayed material coats the second polymeric layer to form an adherent multi-layer coating attached to the fiber reinforced.

  • Patent number: 4782538
    Abstract: A reservoir assembly (10) which has transversely extending frame assemblies (11) which support opposed side walls (12/12a). The frame assemblies (11) each have wall supporting members (15) integral with a relatively lightweight base member (16) which extends beneath the bottom wall of the reservoir. A pressure pad (18) disposed centrally above the base member (16) and beneath the bottom wall prevents upward buckling of the base member (16).
