  • Publication number: 20070141025
    Abstract: Provided is a cancer therapeutic agent comprising a cancer targeting molecule linked to a liver-expressed chemokine (LEC). In one embodiment, the cancer targeting molecule is an antibody that targets cancer cells or tumors in vivo. The cancer targeting molecule is associated non-covalently or covalently with LEC. The cancer therapeutic agents of the invention are useful for the treatment of cancer in an individual by reducing the size of a tumor or inhibiting the growth of cancer cells in an individual and/or by inhibiting the development of metastasis. The effectiveness of the therapy using the LEC cancer therapeutic agents can be increased by reducing the activity of immunoregulatory T cells and/or by adoptively transferring immune T cells.

  • Patent number: 7159401
    Abstract: The present invention relates to a system for detecting aerodynamic instabilities in a jet turbine engine having a pressure transducer mounted in the engine. The pressure transducer, welded to a circuit in signal communication with a controller, is adapted to send measured pressure readings from air in a combustion chamber to the controller. The controller, located in spaced apart relation from the engine, is adapted by software to detect pressure patterns from the pressure signals generated by the transducer that are indicative of a stall or surge. A series of fuel and air valves located with compression and combustion chambers of the engine are in signal communication with the controller. The controller in response to detecting pressure signals indicating a stall or surge is operative to signals in the valves to change the air flow, air angle, fuel flow or speed to reduce the possibility of a stall or surge.

  • Publication number: 20060292116
    Abstract: Interleukin-2 (IL-2) mutants having reduced toxicity, which include full-length IL-2, truncated forms of IL-2 and forms of IL-2 that are linked to another molecule are disclosed herein. Particular substitutions within IL-2, particularly within the permeability enhancing peptide region of IL-2 achieve substantial reduction of vasopermeability activity as compared to a wildytpe form of the mutant IL-2 while retaining many of the immune activating properties of IL-2. Invention IL-2 mutants can be used to stimulate the immune system of an animal and may be used in the treatment of various disorders and conditions.
