The present invention describes compositions and methods for treating cardiovascular disease and myocardial infarction using dipeptidyl peptidase inhibitors. Also provided are methods for increasing natriuretic peptide function by administering one or more analogues of B type natriuretic peptide that provide increased stability in the presence of prolyl-specific dipeptidyl peptidases.

The present invention provides methods and compositions for monitoring of subjects suffering from, or being evaluated for, heart failure. A filtered Natriuretic peptide time-series, alone or in combination with other clinical indicia such as weight gain, can be used to estimate a patients hazard (risk of decompensation). The cumulative integral of Natriuretic peptide concentration can be used to estimate cumulative hazard (risk times exposure) over longer periods of exposure, e.g., 14 day periods, or 30 day periods.

This disclosure describe three related novel methods for Recombinase-Polymerase Amplification (RPA) of a target DNA that exploit the properties of the bacterial RecA and related proteins, to invade double-stranded DNA with single stranded homologous DNA permitting sequence specific priming of DNA polymerase reactions. The disclosed methods has the advantage of not requiring thermocycling or thermophilic enzymes. Further, the improved processivity of the disclosed methods allow amplification of DNA up to hundreds of megabases in length.

A new class of nucleic acid substrates for AP endonucleases and members of the glycosylase/lyase family of enzymes is described. Representatives of each family, the enzymes Nfo and fpg, respectively, cleave nucleic acid backbones at positions in which a base has been replaced by a linker to which a variety of label moieties may be attached. The use of these synthetic substrates embedded within oligonucleotides is of utility in a number of applications.

The present invention features novel, diverse, hybrid and engineered recombinase enzymes, and the utility of such proteins with associated recombination factors for carrying out DNA amplification assays. The present invention also features different recombinase systems having distinct biochemical activities in DNA amplification assays, and differing requirements for loading factors, single-stranded DNA binding proteins (SSBs), and the quantity of crowding agent employed.

This disclosure describes related novel methods for Recombinase-Polymerase Amplification (RPA) of a target DNA that exploit the properties of recombinase and related proteins, to invade double-stranded DNA with single stranded homologous DNA permitting sequence specific priming of DNA polymerase reactions. The disclosed methods have the advantage of not requiring thermocycling or thermophilic enzymes, thus offering easy and affordable implementation and portability relative to other amplification methods. Further disclosed are conditions to enable real-time monitoring of RPA reactions, methods to regulate RPA reactions using light and otherwise, methods to determine the nature of amplified species without a need for gel electrophoresis, methods to improve and optimize signal to noise ratios in RPA reactions, methods to optimize oligonucleotide primer function, methods to control carry-over contamination, and methods to employ sequence-specific third specificity probes. Further described are novel properties and approaches for use of probes monitored by light in dynamic recombination environments.


Disclosed is a cell wall C-polysaccharide antigen of Streptococcus pneumoniae which contains not more than 10% by weight of protein, and preferably less which has been purified with 0.1N NaOH prior to deproteinizing. Also disclosed are polyvalent antibodies raised against Streptococcus pneumoniae which have been affinity purified by passing them over a chromatographic affinity matrix to which is coupled the purified and at least partially deproteinized antigen to render them antigen-specific.

This disclosure provides for methods and reagents for rapid multiplex RPA reactions and improved methods for detection of multiplex RPA reaction products. In addition, the disclosure provides new methods for eliminating carryover contamination between RPA processes.


The present invention involves extracting from Legionella bacteria, particularly L. pneumophila bacteria, an essentially protein-free O-polysaccharide or carbohydrate antigen, coupling this antigen to an activated chromatographic column through a protein space molecule which is first conjugated to the antigen, utilizing the column thus prepared for the affinity purification of raw polyvalent antibodies to the same Legionella bacterium from which the O-polysaccharide or carbohydrate antigen was separatedthereby obtaining antigen-specific antibodies which are useful for the rapid detection of the corresponding Legionella bacterium or its antibody in human bodily fluids such as urine, sputum, blood and the like or in environmental samples suspected of harboring theLegionella bacterium.
