Method to Reduce the Bias in the Mean and Variance of Indices of Water Diffusion Anisotropy as Measured by Diffusion Tensor MRI

This invention describes several novel MRI "stains" to measure and display water diffusion anisotropy data obtained by diffusion tensor MRI (DT-MRI). One problem that this invention overcomes is that it significantly reduces the statistical bias in the mean and variance of the measured anisotropy of water diffusion caused by background noise in the MR images. These benefits are achieved by exploiting the idea that fiber tracts exhibiting diffusion anisotropy vary continuously in most regions.

Cell Expansion System For Use In Neural Transplantation

Cell transplantation therapy typically involves transplanting primary cells or immortalized cells into patients. The promising but still inconsistent data stemming from those clinical trials using primary cells in Parkinson's disease are believed to be due to an insufficient number, function and uniformity of the transplanted cells. In an effort to overcome these problems an improved method for isolating, growing and differentiating precursor cells into dopaminergic neurons has been developed.

Retinoids Can Increase the Potency of Anti-Cancer Immunotoxins

A unique method of potentiating the effect of anti-cancer immunotoxins has been developed, thus offering to significantly improve the treatment of a number of cancers as well as autoimmune diseases. Prolonged treatment of human cancers with classical methods such as radiation and chemotherapy, or a combination of both, may cause greater damage than the underlying disease because healthy tissue is often damaged along with diseased tissue.

Methods and Devices for Intramuscular Stimulation in Dysphonia

The invention is presently being licensed to two entities for treating dysphagia. The method and device of the invention can also be used for treating dysphonia, and the Public Health Service seeks a licensee to commercially develop this invention for that purpose. Qualified applicants are preferably those having implantable stimulators capable of inducing intramuscular stimulation of the laryngeal musculature to improve voice in humans. This invention will assist those persons who have chronic long-standing dysphonia.

Methods and Materials for Controlling Stem Cell and Cancer Cell Proliferation and Differentiation

This work describes a novel nucleolar mechanism that controls the cell-cycle progression in CNS stem cells and cancer cells. The inventors identified a novel peptide, nucleostemin, found in the nucleoli of CNS stem cells, embryonic stem cells, and several cancer cell lines and preferentially expressed by other stem cell-enriched populations. When stem cells differentiate, nucleostemin expression decreases rapidly prior to cell-cycle exit both in vitro and in vivo. Depletion or overexpression of nucleostemin reduces cell proliferation in CNS stem cells and transformed cells.

Stem Cell Culture, Monitoring and Storage System

Available for licensing is a closed chamber that provides an environment for long-term culture of stem cells, stems cells of central nervous system (CNS) origin, embryonic stem cells, and other cells. The chamber is designed with top and bottom mounted cover slips that permit the observation of cells in culture under an optical microscope. This chamber has the ability to control volume and pressure of liquids and gases by an inlet tube and outlet tubes at two different vertical positions.

Establishment of Induced Pluripotent Stem Cells (iPSC) from the Thirteen-lined Ground Squirrel

The limited choice in cell types available for in vitro studies has become an obstacle in hibernation research. 

Researchers at the National Eye Institute for the first time have successfully established iPSC line(s) from a mammalian hibernator, which can be potentially used to generate various cell types and tissue models for in-depth mechanistic studies of hibernation and coldness tolerance in vitro. 

Alpha-galactosidase-A Knockout Mouse Model for Studying Fabry Disease

This technology includes an alpha-galactosidase-A knockout mouse model that can be used to study Fabry disease, an X-linked lysosomal storage disorder. Alpha-galactosidase-A is a crucial enzyme responsible for the breakdown of glycolipids, particularly globotriaosylceramide (Gb3), within lysosomes. In Fabry disease, a rare and inherited lysosomal storage disorder, mutations in the GLA gene lead to deficient or non-functional alpha-galactosidase-A enzyme activity.

High Relaxivity Mulitivalent Gadolinium on a Peptide Scaffold for Targeted MRI Applications in Disease Diagnosis

This technology includes a peptide containing alternating Alanine and Lys(DOTA-Gd) residues can be used to increase the MRI relaxivity of a peptide. The low molecular weight construct can be appended to proteins, antibodies and peptides to increase MRI signals. This approach offers advantages over previous dendrimeric constructs.
