Denoising of Dynamic Magnetic Resonance Spectroscopic Imaging Using Low Rank Approximations in the Kinetic Domain

Accurate measurement of low metabolite concentrations produced by medically important enzymes is commonly obscured by noise during magnetic resonance imaging (MRI). Measuring the turnover rate of low-level metabolites can directly quantify the activity of enzymes of interest, including possible drug targets in cancer and other diseases. Noise can cause the in vivo signal to fall below the limit of detection. A variety of denoising methods have been proposed to enhance spectroscopic peaks, but still fall short for the detection of low-intensity signals.

Video Monitoring and Analysis System for Vivarium Cage Racks

This invention pertains to a system for continuous observation of rodents in home-cage environments with the specific aim to facilitate the quantification of activity levels and behavioral patterns for mice housed in a commercial ventilated cage rack.  The home-cage in-rack provides daytime and nighttime monitoring with the stability and consistency of a home cage environment.

Henipavirus Vaccine

Henipaviruses are RNA viruses containing two high consequence human pathogens: Nipah virus (NiV) and Hendra virus (HeV). Both NiV and HeV infection in humans can result in severe respiratory disease and/or severe neurological manifestations, with mortality rates as high as 80%. There are currently no FDA-approved vaccines or therapeutics, and both NiV and HeV are considered dangerous emerging human pathogens with pandemic potential.

Monoclonal Antibodies to Fentanyl Analogs for Research, Therapeutics, and Novel Diagnostics

Fentanyl is a synthetic opioid drug approved by the Food and Drug Administration for use as an analgesic (pain relief) and anesthetic. However, synthetic opioids, such as fentanyl, are prone to abuse and are the primary drivers of overdose related deaths in the United States. As little as two milligrams of fentanyl can be lethal. Furthermore, structural variants of fentanyl, often mixed with other drugs or counterfeit pills are illegally distributed without the user’s knowledge.

Novel Antiviral—Griffithsin Derived from Algae—for Prophylaxis or Treatment of Rabies Infection

Rabies virus (RABV) infection leads to fatal encephalitis—inflammation of the brain—if left untreated. Millions of people survive RABV infection each year due to timely administration of post-exposure treatment, however, nearly 60,000 people die from rabies each year according to the World Health Organization. Obstacles to timely treatment for RABV infection include the high cost and burdensome storage requirements (i.e., refrigeration) of current post-exposure treatments (i.e., rabies immunoglobulin (RIG)).

Monoclonal Antibody that Detects a Subclass of Dog IgG—for Diagnostic and Research Applications

CDC and collaborating researchers have developed a new monoclonal antibody that recognizes canine IgG (likely IgG4 subclass). This anti-dog IgG reagent could be used to detect antibody reactions to a variety of antigens and has potential use in a wide variety of diagnostic or research applications.

Monoclonal Antibodies for Detection of Rabies Virus Antigen and Confirmatory Rabies Diagnosis

According to the World Health Organization (WHO), rabies causes greater than 59,000 deaths every year in over 150 countries as of 2017. A rapid and reliable diagnostic test for rabies is critical for prophylaxis considerations in humans bitten by animals as well as for basic surveillance and animal rabies control programs. The World Organization of Animal Health (OIE) and WHO Expert Committee on Rabies recently approved the direct rapid immunohistochemical test (DRIT) for rabies diagnostics.

Stable Human Cell Lines Expressing Flavivirus Virus-Like Particles (VLPs) for Vaccine, Biologics, and Diagnostic Development

Flaviviruses such as Zika virus, dengue virus, West Nile virus, yellow fever virus, and Japanese encephalitis virus cause widespread illness and death throughout the world. Typically, flaviviruses get transmitted through the bite of infected mosquitoes and ticks.

Nucleic Acid Amplification Technique for Rapid Diagnostic Analysis

CDC researchers developed a simple target-specific isothermal nucleic acid amplification technique, termed Genome Exponential Amplification Reaction (GEAR). The method employs a set of four primers (two inner and two outer). The outer primer pair targets three specific nucleic acid sequences at a constant 60°C, while the inner pair of primers accelerates and improves the sensitivity of the assay. The GEAR technique is an improvement over loop-mediated isothermal amplification (LAMP) in three ways.
