Use of Detector Response Curves to Optimize Settings for Mass Spectrometry

This CDC developed optimization technology allows one to characterize the behavior of the coefficient of variation (CV) for a range of mass spectrometer machine settings. Surface-enhanced laser desorption/ionization (SELDI) and matrix-assisted laser desorption/ionization (MALDI) are used for the early detection of numerous diseases, for example cervical cancer . A critical step in the analytical process is the optimization of experiment and machine settings to ensure the best possible reproducibility of results, as measured by the CV.

Oxytocin Conditional Knockout Mouse Model for Studying Behavioral Effects

This invention relates to a novel mouse model that permits temporal and spatial inactivation of the oxytocin receptor. Oxytocin is a neurohormone that has been associated with human diseases such as autism and schizophrenia. The use of animal models to study oxytocin disease progression has been invaluable. However, existing mouse models have been limited to knockouts which leads to early mortality. Researchers at the National Institute of Mental Health (NIMH) generated the conditional oxytocin receptor knockout mice using the Cre-loxP and FLP-FRT systems.

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.

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.

Generation of Artificial Mutation Controls for Diagnostic Testing

This technology relates to a method of generating artificial compositions that can be used as positive controls in a genetic testing assay, such as a diagnostic assay for a particular genetic disease. Such controls can be used to confirm the presence or absence of a particular genetic mutation. The lack of easily accessible, validated mutant controls has proven to be a major obstacle to the advancement of clinical molecular genetic testing, validation, quality control (QC), quality assurance (QA), and required proficiency testing.

Automated Microscopic Image Acquisition, Compositing and Display Software Developed for Applied Microscopy/Cytology Training and Analysis

Micro-Screen is a CDC developed software program designed to capture images and archive and display a compiled image(s) from a portion of a microscope slide in real time. This program allows for the re-creation of larger images that are constructed from individual microscopic fields captured in up to five focal planes and two magnifications. This program may be especially useful for the creation of data archives for diagnostic and teaching purposes and for tracking histological changes during disease progression.

Method to Detect and Quantify In Vivo Mitophagy

This technology includes a transgenic reporter mouse that expresses a fluorescent protein called mt-Keima, to be used to detect and quantify in vivo mitophagy. This fluorescent protein was originally described by a group in Japan and shown to be able to measure both the general process of autophagy and mitophagy. We extended these results by creating a living animal so that we could get a measurement for in vivo mitophagy. Our results demonstrate that our mt-Keima mouse allows for a straightforward and practical way to quantify mitophagy in vivo.

Methods To Regulate Metabolism For Treatment Of Neural Injuries and Neurodegeneration

Axonal injury and subsequent neuronal death underpin the pathology of many neurological disorders from acute neural injuries (motor vehicle crashes, combat related injuries, traumatic brain injuries) to neurological diseases (multiple sclerosis, glaucoma). In the central nervous system (CNS), microglia help respond to CNS injuries by mediating the immune response and increasing inflammation at the site of injury. 

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.
