This technology includes an alternative source of plasmid DNA produced in eukaryotic cells for non-viral gene transfer, which represent a novel eukaryotic alternative to bacterial plasmid DNA. Once introduced into non-dividing cells, ceDNA persists and transgene expression remains stable whereas plasmid (p) DNA is lost. The ceDNA and transfection reagent complex is nonimmunogenic allowing re-administration as needed: recombinant adeno-associated virus (rMV) is immunogenic precluding repeated administration.

This technology includes a versatile intravascular 3D intracardiac echocardiography (ICE) catheter that can operate under conventional X-ray and MRI for use during interventional cardiac procedures. The 3D MRICE and custom, GPU-based, real-time imaging system are also included. Structural heart disease affects more than 2.9% of the US population, and common interventional procedures can be difficult because of limitations in catheter devices and inadequate image guidance.

This technology includes a new technique to improve the fidelity of time-varying signals acquired in the dynamic contrast enhanced (DCE) imaging. This technique enhances the time-varying signals in a given DCE image series through deep convolutional neural networks (CNN) to learn the relationship of signal versus contrast concentration from other series of different contrast doses.

The invention provides identification methods for agents which inhibit the Jak-STAT signaling transduction pathway. Drugs identified by these methods are candidates for the treatment of proliferative disorders dependent on the Jak-STAT pathway, including those caused by HTLV-1. In addition, such agents may be potent immunosuppressive drugs with potential applications not only for organ transplantation but also for treatment of autoimmune diseases.

Nestin is an intermediate filament protein first described in early embryonic neuroepithelial stem cells. Although not found in most cells of the mature CNS, nestin is the predominant marker used to detect the small population of undifferentiated cells. The presence of nestin identifies stem, progenitor and some tumor cells in the CNS, and also labels areas of reactive gliosis in the CNS. Available methods to detect nestin use antibodies generated against rat nestin protein.

The current invention provides a nucleic acid sequence comprising the genome of infectious hepatitis C viruses (HCV) of genotype 2a. The encoded polyprotein differs from those of the infectious clones of genotypes 1a and 1b (U.S. Patent 6,153,421) by approximately thirty (30) percent. It covers the use of this sequence and polypeptides encoded by all or part of the sequence, in the development of vaccines and diagnostic assays for HCV and the development of screening assays for the identification of antiviral agents for HCV. Additional information can be found in Yanagi et al.

The current invention provides nucleic acid sequences comprising the genomes of infectious GB virus B, the most closely related member of the Flaviviridae to hepatitis C virus (HCV). It also covers chimeric GBVB-HCV sequences and polypeptides for use in the development of vaccines and diagnostic assays for HCV and the development of screening assays for the identification of antiviral agents for HCV. Additional information can be found in Bukh et al. (1999), Virology 262, 470-478.

The current invention provides nucleic acid sequences comprising chimeric viral genome of hepatitis C Virus (HCV) and bovine viral diarrhea viruses (BVDV). The chimeric viruses are produced by replacing the structural region or a structural gene of an infectious BVDV clone with the corresponding region or gene of an infectious HCV. It covers the use of these sequences and polypeptides encoded by all or part of the sequences in the development of vaccines and diagnostic assays for HCV and the development of screening assays for the identification of antiviral agents for HCV.

The claimed invention provides highly specific and sensitive methods for in vivo, in vitro, or ex vivo imaging of specific extracellular protease activity using an anthrax binary toxin system. The system targets cells that express extracellular proteases of interest. Such a system would be highly useful since various studies have demonstrated a positive correlation between the activity of extracellular proteases and various diseases and undesirable physiological conditions.

Hearing loss is a common communication disorder affecting nearly 1 in 1,000 children in the United States alone, and nearly 50% of adults by the age of eighty. Hearing loss can be caused by environmental and disease-related factors; however, hearing loss due to genetic factors accounts for approximately 50% of cases.
