  • Patent number: 6436864
    Abstract: Unsaturated nitrogenous compounds are used as electron donors in conjunction with catalytic polymerization of addition polymerizable monomers such as olefins, using supported Ziegler-Natta catalysts. The electron donors may be used in the preparation of catalyst systems, thus serving as “internal” electron donors, or they may be added during or just prior to polymerization, as an “external” electron donor.

  • Patent number: 6423685
    Abstract: A method is provided for preparing a biologically active molecule having an increased serum half-life. The method involves conjugating a polymer such as polyethylene glycol to the biologically active molecule. Also provided are polypeptide drugs having an increased serum half-life, e.g., human urokinase plasminogen activator (human “uPA” or “hUPA”) or a fragment or derivative thereof. Pharmaceutical compositions containing such molecules and methods of using them to treat uPA-mediated and uPA receptor-mediated disorders are also provided.

  • Patent number: 6422528
    Abstract: A sacrificial plastic mold having an electroplatable backing is provided. One embodiment consists of the infusion of a softened or molten thermoplastic through a porous metal substrate (sheet, screen, mesh or foam) and into the features of a micro-scale molding tool contacting the porous metal substrate. Upon demolding, the porous metal substrate will be embedded within the thermoplastic and will project a plastic structure with features determined by the mold tool. This plastic structure, in turn, provides a sacrificial plastic mold mechanically bonded to the porous metal substrate which provides a conducting support suitable for electroplating either contiguous or non-contiguous metal replicates. After electroplating and lapping, the sacrificial plastic can be dissolved to leave the desired metal structure bonded to the porous metal substrate. Optionally, the electroplated structures may be debonded from the porous substrate by selective dissolution of the porous substrate or a coating thereon.

  • Patent number: 6416164
    Abstract: The present invention provides a method and device for the acoustic ejection of fluid droplets from fluid-containing reservoirs using focusing means having an F-number greater than approximately 2. The droplets are ejected toward designated sites on a substrate surface for deposition thereon. In one embodiment, the device is comprised of: a plurality of reservoirs each adapted to contain a fluid; an ejector comprising a means for generating acoustic radiation and a large F-numbered means for focusing the acoustic radiation at a focal point near the fluid surface in each of the reservoirs; and a means for positioning the ejector in acoustically coupled relationship to each of the reservoirs. The invention is useful in a number of contexts, particularly in the preparation of biomolecular arrays.

  • Patent number: 6369114
    Abstract: Methods, formulations and kits are described for resuscitating a patient suffering from cardiac arrest, for enhancing the efficacy of cardiopulmonary resuscitation, for treating post-resuscitation hypotension, and for reducing the incidence of ventricular arrhythmias and myocardial dysfunction in a patient following cardiopulmonary resuscitation. Prior methods and agents often cause inotropic or chronotropic effects, which can lead to undesirable post-resuscitation myocardial dysfunction. The invention comprises administering a therapeutically effective amount of an &agr;2-receptor agonist that does not cross the blood-brain barrier, such as &agr;-methylnorepinephrine, to enhance cardiopulmonary resuscitation.

  • Patent number: 6307057
    Abstract: Acid addition salts of imidazolidinones are provided as catalysts for transforming a functional group within a first reactant by reaction with a second reactant. Exemplary first reactants are &agr;,&bgr;-unsaturated carbonyl compounds such as &agr;,&bgr;-unsaturated ketones and &agr;,&bgr;-unsaturated aldehydes. Chiral imidazolidinone salts can be used to catalyze enantioselective reactions, such that a chiral product is obtained from a chiral or achiral starting material in enantiomerically pure form.

  • Patent number: 6291023
    Abstract: The present invention features novel methods and compositions for coating textile substrates, wherein the coating compositions are composed of a coating agent selected from one of (a) an azetidinium polymer, (b) a guanidine polymer, (c) a mixture of an azetidinium polymer and a guanidine polymer, and (d) a copolymer of an azetidinium monomer and a guanidine monomer. Textile substrates coated with the compositions provide high quality printed images when printed with an ink containing a reactive dye having ionizable and/or nucleophilic groups capable of reacting with the coating agent in the textile coating composition. Images printed on a textile substrate coated with a coating composition of the invention are bleed-resistant, water-resistant (e.g., water-fast), detergent-resistant (e.g., detergent-fast), and/or are characterized by an enhanced chroma and hue.
