Abstract: Described herein are systems and methods of providing a nanosensor chip for detecting and/or quantifying target molecules in a solution. Said nanosensor chip comprises a pore comprising a plurality of nanopores. Said plurality of nanopores is functionalized with immobilized probe molecules for detecting the target molecules. The solution is directed to the nanochip to permit binding of said target molecules. Changes an aggregate current in response to target molecules in the liquid sample binding to the probe molecules are measured to detect and/or quantify said target molecules in said solution.

Abstract: A nanosensor chip for detecting and/or quantifying target molecules in a liquid sample includes a semiconductor or other substrate and one or more electrode structures. The substrate has one or more compound nanopores, referred to as “compores.” Each compore is an aperture formed in the substrate and comprises a plurality of nanopores. Each of the nanopores is functionalized with immobilized probe molecules for detecting the target molecules. For each compore, a corresponding electrode structure is laid out on the substrate. The electrode structure has a shape and a position relative to the compore to apply an electric field across all of the nanopores in the compore and to provide a conductive path for an aggregate current through all of the nanopores in the compore. The aggregate current changes in response to target molecules in the liquid sample binding to the probe molecules as a function of the electric field.

Abstract: The invention provides mixtures of linear nucleic acid probes, including circularizing “capture” probes, capable of massively multiplex capture of one or more sequences of interest from a plurality of target organisms. The methods provided by the invention enable rapid, precise, and economical detection of one or more organisms of interest, such as common pathogens.

Abstract: A rapid diagnostic assay for influenza virus, particularly avian influenza and more particularly H5N1, is described. The assay is based on amplification of a significant portion of the hemagglutinin (HA) gene and sequencing of several loci within the HA gene, using techniques which can obtain real time sequence information from multiple sites of a target DNA, in particular pyrosequencing and bioluminescence regenerative cycle. The assay contemplates the use of information-rich subsequences within the HA gene, e.g., (1) a glycosylation sequon; (2) receptor binding site; and (3) HA1/HA2 cleavage site. Other subsequences for sequencing include strain and clade markers, which vary among H5N1 strains.

Abstract: Porcine nucleic acid sequences flanking potentially infectious porcine endogenous retroviral (PERV) insertion sites have been identified and isolated. The unique flanking sequences include porcine nucleic acid sequences that flank the 3? end and porcine nucleic acid sequences that flank the 5? end of PERV insertion sites. The present invention provides compositions and methods for detecting presence of PERV in a sample, particularly those with infectious potential. In addition, the invention relates to breeding of pigs or selection of porcine tissue that is free of infectious PERV for use as a xenotransplant tissue.

Abstract: Multiple agent therapy for treatment of sexual dysfunction, including male erectile dysfunction, with sequential administration a type V phosphodiesterase inhibitor (PDE-5), such as sildenafil, preferably wherein the PDE-5 inhibitor is administered by oral dose means, and a melanocortin 3 and/or 4 receptor agonist, such as Ac-Nle-cyclo(-Asp-His-D-Phe-Arg-Trp-Lys)-OH (PT-141) preferably wherein the PT-141 is formulated for and administered by intranasal means, and further preferably wherein the PDE-5 inhibitor is administered prior to PT-141.
