Genetic Mutations Associated with Stuttering

NIH investigators, for the first time, identified specific mutations associated with stuttering. These mutations are located within the genes encoding three enzymes, Glc-NAc phosphotransferase catalytic subunit [GNPTAB], Glc-NAc phosphotransferase recognition subunit [GNPTG], and N-acetylglucosamine-1-phosphodiester alpha-N-acetylglucosaminidase [NAGPA]. Together these constitute the pathway that targets lysosomal enzymes to their proper location.

A Locking Device for Permanently Securing Surgical Suture Loops

This technology relates to a device that can be used to non-invasively secure surgical suture loops when combined with a percutaneous delivery system. It has been shown to be effective in correcting mitral valve regurgitation (MVR) in an animal model. During the procedure, a guidewire is percutaneously conveyed to the atrium of the heart and is used to secure the "cerclage" suture encircling the mitral valve annulus, which is delivered using a delivery catheter.

Monoclonal Antibodies That React With the Capsule of <i>Bacillus anthracis</i>

Bacillus anthracis is the causative agent of anthrax and is surrounded by a polypeptide capsule of poly-gamma-D-glutamic acid (gammaDPGA). gammaDPGA is poorly immunogenic and has antiphagocytic properties. The bacterial capsule is essential for virulence. Antibodies to the capsule have been shown to enhance phagocytosis and killing of encapsulated bacilli. These antibodies in combination with antibodies that neutralize the toxins of B. anthracis could provide enhanced protection by their dual antibacterial and antitoxic activities.

Non-Contact Total Emission Detection Methods for Multiphoton Microscopy: Improved Image Fidelity and Biological Sample Analysis

The technology offered for licensing and for further development is in the field of multiphoton microscopy (MPM). More specifically, the invention pertains to optical designs that can enhance and extend the capabilities of MPM in spectral imaging of biological samples. The unique design of the light collection and the detection optics maximizes the collection of emitted light, thus increasing the signal and hence the signal-to-noise ratio (SNR).

Caspase Inhibitors Useful for the Study of Autoimmune or Inflammatory Diseases

Novel and potent caspase 1 inhibitors are available for licensing. In particular, this technology discloses potent and selective caspase 1 inhibitors that target the active site of the enzyme. Caspase 1 is known to play a pro-inflammatory role in numerous autoimmune and inflammatory diseases and therefore represents an excellent target for treatment of a broad range of diseases, including but not limited to Huntington's, amyotrophic lateral sclerosis, ischemia, rheumatoid arthritis, osteoarthritis, inflammatory bowel disease, and sepsis.

Myosin-Based Protein-Protein Interaction Assay

Investigators at the National Institute on Deafness and Other Communication Disorders (NIDCD) have developed an assay for the detection of protein-protein interactions in living cells. This assay uses readily-available reagents and straightforward techniques that avoid the difficulty of purifying proteins or generating antibodies required for other binding studies. Proof-of-concept for this assay has been demonstrated, and a manuscript is in preparation for publication.

Improved Standard for Immune System Recovery Assay

Monitoring an immune system that has been depleted by infection (e.g., HIV), chemotherapy, or progenitor cell transplantation is vital to assessing individual’s recovery status. This technology provides a new plasmid standard to be used as part of the existing TREC assay. This new plasmid has a shorter insert than the commercially available one, which means it now matches the PCR product generated in the qPCR reaction in the TREC assay. Additionally, the new plasmid is easier to grow up than the existing standard.

Methods and Devices for Transcatheter Cerclage Annuloplasty

The invention relates to techniques and devices for cardiovascular valve repair, particularly annuloplasty techniques and devices in which tensioning elements are positioned to treat regurgitation of the mitral valve or tricuspid valve. More specifically, the technology pertains to a new device for myocardial septal traversal ("cerclage reentry") that also serves to capture (ensnare) and externalize the traversing guidewire.

Monoclonal Antibodies Against Poliovirus

Early work by Hammond at al. showed gamma globulin to be effective for the prevention of poliomyelitis. Therefore, passive immunotherapy could be another way to treat chronic excretors. Even though prior attempts to use intravenous immunoglobulin (IVIG) and breast milk were unsuccessful, there is reason to think that higher doses of antipoliovirus antibodies could result in complete clearance of poliovirus from chronically infected individuals.
