  • Patent number: 9050547
    Abstract: Improved screen filter modules, related compartmentalized filtration modules, and related filtration processes, suitable for filtering fluid to eliminate suspended particulate matter, such as living cells or microcarriers anchoring living cells, or to separate particulate matter based on size. The improvement is the presence of a barrier that channels redirected filtrate to the portion of the filter most susceptible to clogging by the particulate matter and induces flow patterns that act against clogging.

  • Publication number: 20130193052
    Abstract: If one manufactures chromatography column tubes from plastic/thermoplastic or composite materials (such as polypropylene (PP), polyethylene (PE), polyamides, acetals, or glass-filled plastics, such as glass-fiber plastics) and secures at least one of two flow distributors within the column tube with a tight interference or press fit, the resulting chromatography columns reduce or avoid the formation of dead zones around the press fit flow distributor and have an infinitely adjustable packing medium volume, also known as the medium “bed height.

  • Patent number: 7091182
    Abstract: A novel relationship between pancreatico-biliary secretion and autistic syndrome is disclosed. This relationship enables a novel therapy for the treatment of the symptoms of autistic syndromes, comprising the administration of a therapeutically effective, preferably intravenous, dose of secretin to an individual with autistic syndrome. The relationship further enables a differential diagnosis for autistic syndrome, comprising an analysis of an individual's blood and/or intestinal tissue for the presence of secretin and comparison of the level of secretin to known norms.

  • Publication number: 20050196402
    Abstract: CTLA4-immunoglobulin fusion proteins having modified immunoglobulin constant region-mediated effector functions, and nucleic acids encoding the fusion proteins, are described. The CTLA4-immunoglobulin fusion proteins comprise two components: a first peptide having a CTLA4 activity and a second peptide comprising an immunoglobulin constant region which is modified to reduce at least one constant region-mediated biological effector function relative to a CTLA4-IgG1 fusion protein. The nucleic acids of the invention can be integrated into various expression vectors, which in turn can direct the synthesis of the corresponding proteins in a variety of hosts, particularly eukaryotic cells. The CTLA4-immunoglobulin fusion proteins described herein can be administered to a subject to inhibit an interaction between a CTLA4 ligand (e.g., B7-1 and/or B7-2) on an antigen presenting cell and a receptor for the CTLA4 ligand (e.g.

  • Patent number: 6790825
    Abstract: Secretin and secretin compositions are used for the treatment of autism and other neurological, behavioral and immunological disorders. The method includes administering an effective amount of secretin, such as Secretin-Ferring, to a patient. In one example, 2 clinical units (CU) of Secretin-Ferring was dissolved in a 7.5 ml solution of sodium chloride and was intravenously injected over 1 minute. In another example, secretin was administered transdermally by applying dimethyl sulfoxide (DMSO) to the patients skin and rubbing about 15 CU of Secretin-Ferring into the DMSO. Other methods and compositions for administering the effective amount of secretin include other transdermal carrier substances, such as gels, lotions, or patches; oral carriers, such as tablets, capsules, or lozenges; inhalation through the nose or mouth (e.g., as an aerosol); suppository forms of secretin and secretin compositions; and using acoustic waves to cause the secretin to penetrate the skin.

  • Patent number: 6727231

  • Patent number: 6719972
    Abstract: Isolated ligands which bind a molecule expressed on the surface of T cells and induce antigen specific apoptosis in activated T cells are disclosed. Preferably, the T cell surface molecule is CTLA4 and the ligand is a monoclonal anti-CTLA4 antibody that binds to an epitope of CTLA4 distinct from the binding sites of B7-1 and B7-2. Upon binding of the antibody to CTLA4 on an activated T cell, in the presence of an antigenic signal, antigen specific apoptosis is induced. The invention also describes a novel natural CTLA4 ligand, distinct from B7-1 and B7-2, which mediates induction of apoptosis. Pharmaceutical compositions of anti-CTLA4 antibodies or other isolated CTLA4 ligands which can be administered to subjects to induce T cell apoptosis, thereby clonally deleting antigen specific. T cells, such as alloreactive T cells in transplantation situations or autoreactive T cells in autoimmune disorders, are also disclosed.

  • Patent number: 6365593
    Abstract: The invention is based on the discovery that the levels of one or more methylxanthines in urine samples are significantly decreased in children diagnosed with symptoms of autistic disorder, compared to the levels in normal children, and that levels of xanthines in urine are increased in autistic children. Consequently, the presence in the urine of levels of methylxanthines below a certain range and the level of xanthine above a certain range, are diagnostic of autistic disorder. In another aspect, one or more of these methylxanthines can be used to treat individuals exhibiting symptoms of autistic disorder.
