  • Patent number: 6875420
    Abstract: Disclosed herein are agents for enhancing the contrast in an ultrasound image. These agents are extremely small bubbles, or “microbubbles,” comprised of specially selected gases. The microbubbles described herein exhibit long life spans in solution and may be produced at a size small enough to traverse the lungs, thus enabling improved ultrasound imaging of the cardiovascular system and other vital organs. Also disclosed herein is a method for selecting gases from which contrast agents may be produced. The method is based on calculations using inherent physical properties of gases and describes a means to associate the properties of a gas with the time for dissolution of microbubbles comprised of the gas.

  • Publication number: 20040258663
    Abstract: Compositions and methods are provided for intranasal delivery of interferon-&agr; yielding improved pharmacokinetic and pharmacodynamic results. In certain aspects of the invention, the interferon-&agr; is delivered to the intranasal mucosa along with one or more intranasal delivery-enhancing agent(s) to yield substantially increased absorption and/or bioavailability of the interferon-&agr; and/or a substantially decreased time to maximal concentration of interferon-&agr; in a tissue of a subject as compared to controls where the interferon-&agr; is administered to the same intranasal site alone or formulated according to previously disclosed reports. The enhancement of intranasal delivery of interferon-&agr; according to the methods and compositions of the present invention allows for the effective pharmaceutical use of these agents to treat a variety of diseases and conditions in mammalian subjects.

  • Publication number: 20040253211
    Abstract: A method for treating cancer in a mammal comprised of administering a therapeutically effective amount of an agent that induces the expression of one or more claudins within a cancerous cell. Preferably the claudin is claudin-3, claudin-4 aor claudin-9. In a preferred method, a nucleic acid that encodes a claudin is administered to the mammal under conditions wherein the nucleic acid is transfected into the cancerous cell and the claudin is produced in the cell. Also disclosed is a method for diagnosing cancer comprising determining the presence of a claudin 3, 4 or 9 in a cell that normally expresses the protein. If the cell does not express the claudin, then it is cancerous.

  • Publication number: 20040077540
    Abstract: Compositions and methods are provided that include a biologically active agent and a permeabilizing agent effective to enhance mucosal delivery of the biologically active agent in a mammalian subject. The permeabilizing agent reversibly enhances mucosal epithelial paracellular transport, typically by modulating epithelial junctional structure and/or physiology at a mucosal epithelial surface in the subject. This effect typically involves inhibition by the permeabilizing agent of homotypic or heterotypic binding between epithelial membrane adhesive proteins of neighboring epithelial cells. Target proteins for this blockade of homotypic or heterotypic binding can be selected from various related junctional adhesion molecules (JAMs), occludins, or claudins. The permeabilizing agent is typically a peptide or peptide analog or mimetic, often selected or derived from an extracellular domain of a mammalian JAM, occludin or claudin protein.
