A Highly Efficient Nociceptor Differentiation Protocol for Human Pluripotent Stem Cells

This technology includes a robust and highly efficient protocol that differentiates human pluripotent stem cells (hPSCs) exclusively into nociceptors (also called sensory neurons) under chemically defined conditions. The use of hPSCs, including hESCs and iPSCs, holds great promise for drug screening, disease modeling, toxicology, and regenerative medicine. However, efficient and highly reproducible protocols have not been developed for most cell types that are relevant and urgently needed for translational applications.

A Highly Efficient Astrocyte Differentiation Protocol for Human Pluripotent Stem Cells

This technology includes a robust and highly efficient protocol that differentiates induced pluripotent stem cells (iPSCs) exclusively into nociceptors (also called sensory neurons) under chemically defined conditions. The use of hPSCs, including hESCs and iPSCs, holds great promise for disease modeling, drug discovery, and cell therapy. However, efficient and highly reproducible protocols have not been developed for most cell types that are relevant and urgently needed for translational applications.

A Novel High-Throughput Assay for Identifying Zike Virus NS2B-NS3 Protease Inhibitors

This invention includes a novel high-throughput assay to identify orthosteric inhibitors blocking the Zika virus NS2B-NS3 protease. Pathogenic flaviviruses, including Zika, require the NS2B-NS3 protease for viral replication. There is currently an unmet need for specific antiviral therapeutics against the Zika virus. Preliminary screening using the NCGC Pharmaceutical Collection library identified a group of drugs including temoporfin, erythrosin B, niclosamide, and nitazoxanide that can significantly inhibit the interactions between NS2B and NS3.

Fibroblast Cell Lines (with L444P/RecNci1 Genotype) for the Screening of Small Molecules for Gaucher Disease Treatment

This technology includes two human fibroblast cell lines to be used to study the defects in GBA1 gene and protein and to screen small molecules for involvement in Gaucher disease. Glucocerebrosidase (GBA1 or GCase or beta-glucosidase) is a lysosomal enzyme, responsible for breakdown of a fatty material called glucocerebroside (or glucosyl ceramide). Deficiency or malfunction of GBA1 leads to the accumulation of insoluble glucocerebrosides in tissues, which is a major symptom of Gaucher disease.

Codon Deoptimized (CD) Poliovirus Seed Strains for Use in an Inactivated Poliovirus Vaccine

Polio is a disabling and potentially fatal infectious disease. Sabin Oral Poliovirus Vaccine (OPV) and Salk Inactivated Poliovirus Vaccine (IPV) have been crucial in the global poliovirus eradication efforts and substantial decrease in disease incidence rates. However, recent findings showed that Sabin OPV strains, due to their genetic instability, may revert to virulence and spread among communities, resulting in circulating vaccine-derived poliovirus (cVDPV). Salk IPV, which is made by inactivating live poliovirus,

Isotopes of Alpha Ketoglutarate and Related Compounds for Hyperpolarized MRI Imaging

This technology includes 1-13C-ketoglutarate which can be used for imaging the conversion to hydroxyglutarate (HG) or Gln in cancer cells with an IDH1 mutations by hyperpolarized MRI. The ability to detect the status of IDH1 mutations is clinically prognostic for multiple cancers. These exciting observations are limited by two factors, the major one being that the natural abundance of 13C at position C5 overlaps with 1-13C-2-hydroxyglutarate peak, which limits the sensitivity of analysis and prevents simultaneous observations of HG and Gln formation.

Systems and Methods for Applying Pressure to the Heart for the Treatment of Tricuspid Valve Regurgitation

This technology includes structures and methods for cinching a band around the heart for treating conditions including tricuspid valve regurgitation (TR). When positioned appropriately along the atrioventricular groove, the band is tightened around the heart which narrows the tricuspid annulus and relieves TR.

Novel Bicuspid Transcatheter Heart Valve Frame and Leaflets for Mitro Valve Implantation

This technology includes a pair of subsystems for a novel transcatheter bicuspid valve (frame and leaflets) intended for implantation in the mitral position. It is simple, it overcomes key limitations to transcatheter bicuspid mitral valve implants, and it overcomes key limitations to transcatheter tricuspid mitral valve implants.

Devices and Methods for Cerclage of Luminal Systems

This technology includes a family of transcatheter endovenous intramyocardial tether (MIRTH) procedures to impose myocardial constraint on the LV (MIRTH), LV and RV (SCIMITAR), and cardiac resynchronization procedures. Included is a set of advanced cardiac treatment technologies that focus on minimally invasive procedures for heart patients. The main technology is the transcatheter endovenous intramyocardial tether (MIRTH) procedure, which is designed to apply physical constraint to the left ventricle (LV) of the heart.

Segmented Metallic MRI Guidewires Using Stiffness-matched Nonconductive Connectors for Catheterization Procedures

This technology includes a metallic guidewire that is suitable for MRI catheterization, because it is mechanically long but electrically consists of short conductive segments that cannot resonate during MRI. The invention consists of stiffness-matched non-conductive connectors or connections that are used along with short metallic segments. The embodiment reduced to practice has torquability and flexibility comparable to marketed metallic guidewires, yet is free from MRI heating.
