  • Patent number: 8454934
    Abstract: A chelation structure and method of forming and using the chelation structure. The chelation structure has a backbone that includes a linear sequence of monomeric backbone units, at least one polymer side chain, and at least one chelator side chain. The side chains are each covalently coupled to the backbone at one of the monomeric backbone units by a bond that is independently biodegradable or non-biodegradable. The chelation structure is synthesized by Radical Addition Fragmentation Transfer (RAFT), Atom Transfer Radical Polymerization (ATRP), or Free Radical Polymerization (FRP). The chelation structure, individually or in combination with a shuttle chelator, may be introduced into a mammal to bind an amount of a substance in a mammal, the substance being at least one of a metal and heme. The chelation structure has a log stability constant exceeding that of the shuttle chelator for binding the substance within cells of the mammal.

  • Patent number: 8067151
    Abstract: A method for storing and using platelets and an associated platelet structure. At least one modified platelet is formed. Each modified platelet includes a platelet and at least one polymerated chemical. Each polymerated chemical includes a polymer covalently bonded directly to the platelet or includes the polymer and a linker molecule such that the linker molecule is covalently bonded to the platelet and the polymer is covalently attached to the linker molecule. The polymer of each polymerated chemical of each modified platelet is polyethylene glycol (PEG) or a PEG derivative. Forming each modified platelet does not include modifying the platelet membrane of each platelet with a glycan-modifying agent. The at least one modified platelet is stored in a temperature range below 0° C. After being stored, the at least one modified platelet may be introduced into a subject to treat a condition related to a reduced platelet function.

  • Patent number: 8007784
    Abstract: The present invention is directed to a non-immunogenic cellular composition comprising: a cell having a cell surface and antigenic determinants on the cell surface; an optional linker molecule covalently attached to the cell surface; and a hydrophilic, biocompatible, non-immunogenicity providing compound or polymer (e.g., polyethylene glycol or a derivative thereof) covalently attached to the linker molecule or directly to the cell. In one embodiment, the linker molecule is covalently attached directly to the antigenic determinant on the cell surface. In an alternate embodiment, the linker molecule may be covalently attached to a non-antigenic site on the cell surface, but will camouflage the antigenic determinant on the cell surface.

  • Patent number: 6699465
    Abstract: A chemo-physiological structure and method for forming the chemo-physiological structure. In a first embodiment, a cell of an animal is provided. The cell has a membrane surface and a viral receptor coupled to the membrane surface. A linker molecule having a covalently attached polymer is covalently bonded to the membrane surface, the viral receptor, or both. The polymer prevents an extracellular virus from bonding to the viral receptor. In a second embodiment, a linker molecule having a covalently attached polymer is covalently bonded to a capsid of a virus, which prevents the virus from bonding to a viral receptor of an adjacent or nearby animal cell.

  • Patent number: 6555656
    Abstract: A prion-physiological structure and associated method of formation. A provided abnormal prion has a transforming power over a normal prion to convert the abnornal prion into defective prion that mimics the abnormal prion. A linker molecule is then bonded to the abnormal prion, wherein a polymer that is covalently attached to the linker molecule facilitates formation of a polymerized abnormal prion that does not have the transforming power over the normal prion.
