Title: Use of isophoronediamine isomer mixtures in polyaddition resins
Inventor: PIANA HERMANN
IPC: C08G59/50
Filed: 1993-04-05
Abstract: ABSTRACT OF THE DISCLOSURE      The invention is directed towards the use of isophoronediamine isomer mixtures consisting of more than 40 % preferably more than 50 to 70 %, of the trans- and less than 60 %, preferably less than 50 to 30 %, of the cis-isomer as reactant in polyaddition resins selected from epoxy, polyurethane and polyurea resins.  As curing agents in epoxy resins compared with previously known isomer mixtures, the isomer mixtures lead to an extended pot life with simultaneously reduced maximum curing temperature and therefore reduced shrinkage problems.  The isomer mixtures are also suitable as amine components with reduced reactivity for the chain extension of polyurethane/polyureas.

Title: Composition and method
Inventor: BUTLER SIDNEY P
IPC: A61K51/08
Filed: 1993-05-05
Abstract: Abstract The present invention provides a radiolabelled t-PA having substantially all plasminogen catalytic sites inactivated and which is able to bind to a thrombus and/or fibrin. It also provides a composition for localising deep venous thrombosis using the compound of this invention, together with a pharmaceutically acceptable carrier, diluent and/or excipient. The invention also provides a process for preparing the compound of this invention, which process comprises reacting t-PA with an agent to inactivate the plasminogen catalytic site followed by cleaving disulfide bridges in the t-PA and labelling the thus-reduced t-PA. The invention specifically provides for the use of recombinant t-PA which is labelled with Tc-99m. Thus the compound of this invention is useful as a radiopharmaceutical for the non-invasive detection of deep vein thrombosis (DVT) in mammals. This radiopharmaceutical has specific thrombus localisation both in vitro and in vivo with an exceptionally fast blood clearance, These properties permit the reliable scintigraphic detection of thrombus in a rabbit model within 60minutes post injection and in humans within 2hr-6hr post injection, In addition, as rt-PA is a product of recombinant DNA technology, it is unlikely to be antigenic and is thus capable of being used more than once in the same mammal.

Title: Macroporous Polymeric Particles as Biocompatible Supports
Inventor: LI NAI-HONG
IPC: C12N11/08
Filed: 1992-09-14
Abstract: A method to prepare uniform populations of macroscopic beads containing pores of at least 0.1 microns diameter is described.  The beads consist essentially of a copolymer of a monoethylenically unsaturated monomer and a crosslinking polyethylenically unsaturated monomer, said resulting copolymer optionally being derivatized with functional groups, linking moieties, and/or affinity ligands.  The macroporous beads are obtained by utilizing, as a porogen in the polymerization reaction, porous inorganic particles which have been preabsorbed with a blowing agent.  The blowing agent is not activated until after the polymerization takes place; when the blowing agent is activated, the organic polymer which isolates the inorganic porogen particles from each other in the bead is destroyed.  Upon subsequent dissolution of the inorganic porogen, a network of pores throughout the organic copolymer-formed particle is formed.  The resulting beads are useful in a variety of chromatographic, analytical and biomedical techniques.
