标 题 :Ammonia facilitated cation loading of zeolite catalysts
发明人：GOFFE RANDAL A
权利人:PACCAR INC
摘要:The present disclosure features a high metal cation content zeolite-based binary catalyst (e.g., a high copper and/or iron content zeolite-based binary catalyst, where the zeolite can be a chabazite) for NO x reduction, having relatively low N 2 O make, and having low corresponding metal oxide content; where the metal in the metal oxide corresponds to the metal of the metal cation. The present disclosure also describes the synthesis of the zeolite-based binary catalyst having high metal cation content.

标 题 :De novo polynucleotide synthesis with substrate-bound polymerase

权利人:MICROSOFT TECHNOLOGY LICENSING LLC
摘要:De novo polynucleotide synthesis is performed with a substrate-bound polymerase. The polymerase is attached to a solid substrate such as a microelectrode array. The polymerase adds nucleotides to growing polynucleotides strands that are also attached to the solid substrate. Spatial control of polymerase activity is achieved by changing the rate of nucleotide polymerization at selected locations on the surface of the solid substrate. The rate of polymerization is changed by inhibiting or promoting activity of the polymerase. In some implementations, activation of electrodes in the microelectrode array changes the rate of nucleotide polymerization. Nucleotides are added to the growing polynucleotide strands at areas where the polymerase is active. By varying the locations where the substrate-bound polymerase is active and the species of nucleotide added, a population of polynucleotides with different, arbitrary sequences is synthesized on the surface of the solid substrate.

标题 :Regulation of polymerase using cofactor oxidation states
发明人：NGUYEN BICHLIEN HOANG
权利人:MICROSOFT TECHNOLOGY LICENSING LLC
摘要:Polynucleotide synthesis performed with a template independent polymerase such as terminal deoxynucleotidyl transferase (TdT) is regulated by controlling the oxidation state of a metal cofactor. The oxidation state of the metal cofactor is changed to +2, thus activating the polymerase, by applying a voltage with electrodes or by introducing a chemical redox reagent. Addressable polynucleotide synthesis creates polynucleotides with different arbitrary sequences through use of spatial control of cofactor oxidation states to add nucleotides only at selected locations on an array. Control of metal oxidation states is regulated by selective activation of a microelectrode array, controlled addition of redox reagents to specific locations on the array, or controlled activation of photocatalysts at specific locations on the array. Scavengers in solution prevent cofactors distant from the selected locations from catalyzing polymerase activity and thereby maintain the localized effect of polymerase activation.

标 题 :Streptokinase derivatives with high affinity for activated platelets and methods of their production and use in thrombolytic therapy
发明人：GALLER LAWRENCE ISAAC
摘要:Streptokinase derivatives having platelet glycoprotein binding domains adjacent to the termini of the streptokinase sequence. These derivatives produce higher local concentrations of plasmin in vivo as compared to unmodified streptokinase. Certain of the derivatives have high affinity for the GPIIB/IIIA receptor and low affinity for the fibronectin and vitronectin receptors. Others have substantially equivalent affinity for all three receptors. The derivatives are useful in treating thromboembolic disorders. The streptokinase derivatives can be made by recombinant techniques or by chemical synthesis or conjugation.

标 题 :Method for ligating adaptors to nucleic acids which methods are useful for obtaining the ends of genes

摘要:The present invention is directed to cloning the ends of genes. Traditionally it has been very difficult to recover the 5' end of a gene. The present invention greatly eases this problem. The invention is a variation on RACE and uses a combination of techniques. Specific genes are purified by using three enrichment steps--1) a polymerase chain reaction, 2) a hybrid capture step, and 3) a second polymerase chain reaction. The inclusion of the hybrid capture step results in a greater enrichment than occurs with RACE. The ends of the gene are retained by use of a novel technique of attaching adaptors at the ends of the nucleic. The 5' end of the gene is conserved by preparing a first strand of cDNA and ligating to this an adaptor which is partially double stranded wherein the overhang or single stranded region of the adaptor is degenerate which allows for a fraction of the adaptor population to hybridize with the first strand of cDNA at the 3' end of the cDNA. This hybridization holds the adaptor in conjunction with the cDNA during the ligation step thereby resulting in a highly efficient ligation. The unique portion of the adaptor is used to design an oligomer to prime the second strand synthesis. None of the 5' sequence is lost in this method thereby allowing for a greater possibility of recovering the extreme 5' end of the gene.

标 题:Synthesis and incorporation of high-temperature ammonia-release agent in lit-end cigarettes
发明人：FOURNIER JAY A; PAINE JOHN B; FERNANDEZ DOUGLAS A
权利人:PHILIP MORRIS USA INC
摘要:A tobacco smoking mixture and/or a cigarette wrapper with high-temperature ammonia-release agents therein are provided, wherein the high-temperature ammonia-release agents are present in an amount effective to reduce the cytotoxicity of gas phase or particulate matter formed during smoking of the cigarette. The high-temperature ammonia-release agents are capable of reducing the cytotoxicity of gas phase or particulate matter by evolving ammonia at temperatures greater than about 200° C., wherein the ammonia can interact with the particulate matter. Additionally, the high-temperature ammonia-release agents can be formed by heating an aqueous mixture of an iron precursor compound, an ammonia source compound and an acid.
