  • Patent number: 6997863
    Abstract: Disclosed are therapeutic methods for the treatment of disease material involving administration of a thermotherapeutic magnetic composition, which contains single-domain magnetic particles attached to a target-specific ligand, to a patient and application of an alternating magnetic field to inductively heat the thermotherapeutic magnetic composition. Also disclosed are methods of administering the thermotherapeutic magnetic material composition. The thermotherapeutic methods may be used where the predetermined target is associated with diseases, such as cancer, diseases of the immune system, and pathogen-borne diseases, and undesirable targets, such as toxins, reactions associated with organ transplants, hormone-related diseases, and non-cancerous diseased cells or tissue.
    Type: Grant

  • Publication number: 20040156852
    Abstract: Methods for treating cells, diseased tissue, pathogens, or other undesirable matter involve the administration of a bioprobe (energy susceptive materials that are attached to a target-specific ligand) to a patient's body, body part, tissue, or body fluid (such as blood, blood plasma, or blood serum). An energy source provides energy to the bioprobe so as to destroy, rupture, or inactivate the target. Various energy forms, such as AMF, microwave, acoustic, or a combination thereof, created via a variety of mechanisms, may be used. The disclosed methods may be useful in the treatment of a variety of indications, including but not limited to, cancer of any type, such as bone marrow, lung, vascular, neuro, colon, ovarian, breast and prostate cancer, AIDS, adverse angiogenesis, restenosis, amyloidosis, tuberculosis, obesity, malaria, and illnesses due to viruses, such as HIV.

  • Publication number: 20040156846
    Abstract: Methods for treating cells, diseased tissue, pathogens, or other undesirable matter involve the administration of a bioprobe (energy susceptive materials that are attached to the target-specific ligand chimeric L6 antibody) to a patient's body, body part, tissue, or body fluid (such as blood, blood plasma, or blood serum). An energy source provides energy to the bioprobe so as to destroy, rupture, or inactivate the target. Various energy forms, such as AMF, microwave, acoustic, or a combination thereof, created via a variety of mechanisms, may be used.

  • Patent number: 5900457
    Abstract: The present invention is directed to aqueous polyurethane dispersions and aqueous polyurethane-acrylic dispersions, especially polymer dispersions formed from norbornane diisocyanate. The dispersions, and the dried polymers therefrom, are useful adhesives that provide enhanced bond strength when subjected to increased thermal and mechanical stress. Additionally, the inventive dispersions form polymers having increased adhesion compared to similar polymers based on cycloaliphatic diisocyanates which are free of a methylene bridge.

  • Patent number: 5834554
    Abstract: A process for the preparation of sulfonated polyurethane-urea polymers, which are useful film to film laminating adhesives for flexible packaging in which the urethane-urea polymer component has no amide linkages. The water-based sulfonated polyurethane prepolymers are processed at reduced temperatures and are substantially free of volatile and/or leachable contaminants.
