Rapid and Sensitive Detection of Nucleic Acid Sequence Variations

The ability to easily detect small mutations in nucleic acids, such as single base substitutions, can provide a powerful tool for use in cancer detection, perinatal screens for inherited diseases, and analysis of genetic polymorphisms such as genetic mapping or for identification purposes. Current approaches make use of the mismatch that occurs between complimentary strands of DNA when there is a genetic mutation, the electrophoretic mobility differences caused by small sequence changes, and chemicals or enzymes that can cleave heteroduplex sites.

Treatment of Alcoholism by Inhibition of the Neuropeptide Y Receptor

Aversive or anticraving medications are currently used to supplement behavioral treatment of alcohol dependence. However, there is a need for developing more effective medications than those available. Neuropeptide Y (NPY) is a neurotransmitter known for increasing appetite and possibly having a role in alcohol preference and dependence. This is likely to be mediated by activation of the post-synaptic NPY-Y1 receptor, but developing molecules suitable for human therapeutics that activate that receptor represents a major challenge.

Genes For Niemann-Pick Type C Disease

Niemann-Pick disease is a class of inherited lipid storage diseases. Niemann-Pick Type C disease is an autosomal recessive neurovisceral lipid storage disorder which leads to systemic and neurological abnormalities including ataxia, seizures, and loss of speech. Patients with the disease typically die as children. The biochemical hallmark of Niemann-Pick Type C cells is the abnormal accumulation of unesterified cholesterol in lysosomes, which results in the delayed homeostatic regulation of both uptake and esterification of low density lipoprotein (LDL) cholesterol.

System for Correction of MRI Head Motion

Motion artifacts continue to be a significant problem in MRI of human brain. Prospective motion correction based on external tracking systems has been proposed to ameliorate this issue. However, the calibration of these systems is very complicated and time consuming, as it requires a camera system calibration as well as a calibration between camera and MRI system using dedicated phantoms. An alternative motion correction method for MRI that does not require calibration and can work with just a single video camera has been developed and is available for licensing.

A Target for the Development of Diagnostics and Therapeutics for Abnormal Hematopoiesis

The zinc finger protein ZFP36L2 has been shown by the inventors to play an essential role in hematopoiesis, a process that is dysregulated in hematological cancers, anemia, and other conditions. Thus, ZFP36L2 has promise for use in a diagnostic test to detect abnormal hematopoiesis, or as a target for the development of therapeutics to treat abnormal hematopoiesis.

Multilayer X-Ray Transmission Grating Array for Phase-Contrast Imaging and Tomography

Classical X-ray Computed Tomography (CT) and radiography are based on X-ray absorption and cannot show soft tissue structures as well as Magnetic Resonance Imaging (MRI). Detecting the phase delay/advance of X-rays that travel through the body could enhance soft tissue contrast 10 - 100 times. Submicron-period X-ray transmission gratings for medical x-ray energies can substantially enhance the phase detection sensitivity, but fabrication is a great challenge. This invention includes a method to fabricate multilayer transmission gratings of large areas.

Treatment of Viral Infection by Blocking Interleukin-21

Blocking interleukin (IL-21) may be an effective method to treat or prevent various viral infections. In the course of an immune response to a virus, IL-21, produced primarily by CD4+ T cells, can inhibit or stimulate (regulate), immune cell function (B cells, T cells, natural killer cells, dendritic cells). IL-21 regulation may be either protective or pathological; autoimmune disease pathology has been associated with IL-21 promoted inflammation (in: type 1 diabetes, lupus, and multiple sclerosis).

SIRT2 Inhibitors as Novel Therapeutics for Myocardial Infarction and Ischemic Stroke and to Prevent Necrosis

Sirtuin 2 (SIRT2) inhibitors to reduce necrosis and, thereby, as novel therapeutics to treat ischemic stroke and myocardial infarction. Accumulating evidence indicates that programmed necrosis plays a critical role in cell death during ischemia-reperfusion. NIH investigators have shown that the NAD-dependent deacetylase SIRT2 binds constitutively to receptor-interacting protein 3 (RIP3) and that deletion or knockdown of SIRT2 prevents formation of the RIP1-RIP3 complex in mice.

Software to Improve the Quality of Microscopy Images

Available for licensing and commercial use is software based on an iterative deconvolution procedure that recovers images that have been blurred by a known point spread function. The software provides superior results when multiple independent observations of the same specimen are obtained. An example of such observations might be the multiple views of a specimen collected by a selective illumination plane microscope (SPIM).
