Major Neutralization Site of Hepatitis E Virus and Use of this Neutralization Site in Methods of Vaccination

Hepatitis E is endemic in many countries throughout the developing world, in particular on the continents of Africa and Asia. The disease generally affects young adults and has a very high mortality rate, up to 20%, in pregnant women. This invention relates to the identification of a neutralization site of hepatitis E virus (HEV) and neutralizing antibodies that react with it. The neutralization site is located on a polypeptide from the ORF2 gene (capsid gene) of HEV.

TMC1, a Deafness-Related Gene

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.

Variable Curve Catheter

The invention provides a deflectable tip guiding device, such as a catheter, that enables the operator to vary the radius of curvature of the tip of the catheter. This is a novel variation on the classic "fixed fulcrum" tip deflectors used in minimally invasive procedures in open surgical treatments. The described device permits a more comprehensive ability to navigate complex geometric pathways in patient's body and enables better access to target structures (e.g., to all endomyocardial walls from a transaortic approach).

Peptide Mimotope Candidates for Otitis Media Vaccine

This technology describes peptide mimotopes of lipooligosaccharides (LOS) from nontypeable Haemophilus influenzae (NTHi) and Moraxella catarrhalis that are suitable for developing novel vaccines against the respective pathogens, for which there are currently no licensed vaccines. The mimotopes not only immunologically mimic LOSs from NTHi and M. catarrhalis but will also bind to antibodies specific for the respective LOS. NTHi and M. catarrhalis are common pathogens that cause otitis media in children and lower respiratory tract infections in adults.

GATA-3 Reporter Plasmids for Revealing Underlying Mechanisms in Breast Cancer

GATA-3 is a transcription factor that is highly expressed in normal cells of the mammary luminal epithelium. GATA-3 plays a regulatory role in determining the fate of cells in the mammary gland. Disruption of GATA-3 expression leads to defects in the development of mammary cells, including an inability to differentiate properly into the correct cell type. GATA-3 function is also disrupted in various breast cancer models indicating that GATA-3 has tumor suppressive properties in normal cells.

Oxynitidine Derivatives as Tyrosyl DNA Phosphodiesterase (TDP) Inhibitors and Radiosensitizers

Summary: 

The National Cancer Institute (NCI) is actively seeking potential licensees and/or co-development research collaboration partners interested in further developing this family of oxynitidine derivatives as tyrosyl-DNA phosphodiesterase 1 (TDP1) inhibitors and radiosensitizers for the treatment of cancer. 

Soluble Antigen-Based ELISA for the Detection of B. malayi Infections

The technology presented is a breakthrough in the diagnosis of lymphatic filariasis, specifically targeting the B. malayi pathogen. It encompasses a novel soluble antigen extract used in both IgG and IgG4-based ELISA tests, aimed at detecting the presence of the filarial infection. This innovation serves as a cornerstone for a CLIA-certified reference test, established and utilized in Dr. Nutman's laboratory since the late 1980s.

Bone Marrow Mesenchymal Stem Cell (BMSC)-Derived Exosomes for the Treatment of Glaucoma

Glaucoma is one of the world’s leading causes of irreversible blindness. There is no cure and vision lost from glaucoma cannot be restored. Glaucoma is associated with fluid build-up in the eye resulting in an increased intraocular pressure (IOP). The pressure may cause damage to the optic nerve and lead to progressive degeneration of retinal ganglion cells (RGC) and vision loss. Currently, available treatments for glaucoma delay progression by reducing IOP, but no therapies exist to directly protect RGC from degradation and loss. 

3D Vascularized Human Ocular Tissue for Cell Therapy and Drug Discovery

Degeneration of retinal tissues occurs in many ocular disorders resulting in the loss of vision. Dysfunction and/or loss of Retinal Pigment Epithelium Cells (RPE) and disruption of the associated blood retinal barrier (BRB) tissue structures are linked with many ocular diseases and conditions including: age-related macular degeneration (AMD), Best disease, and retinitis pigmentosa. Engineered tissue structures that are able to replicate the function of lost BRB structures may restore lost vision and provide insight into new treatments and mechanisms of the underlying conditions. 

Machine Learning and/or Neural Networks to Validate Stem Cells and Their Derivatives for Use in Cell Therapy, Drug Delivery, and Diagnostics

Many biological and clinical procedures require functional validation of a desired cell type. Current techniques to validate rely on various assays and methods, such as staining with dyes, antibodies, and nucleic acid probes, to assess stem cell health, death, proliferation, and functionality. These techniques potentially destroy stem cells and risk contaminating cells and cultures by exposing them to the environment; they are low-throughput and difficult to scale-up.
