Engineering Neural Stem Cells Using Homologous Recombination

Methods for modifying the genome of a Neural Stem Cell (NSC) are disclosed. Also, methods for differentiating NSCs into neurons and glia are described. NSCs are multipotent, self-renewing cells found in the central nervous system, capable of differentiating into neurons and glia. NSCs can be generated efficiently from pluripotent stem cells (PSCs) and have the capacity to differentiate into any neuronal or glial cell type of the central nervous system.

Methods of Treating or Preventing Pruritis (Itch)

This technology provides a novel method of treating or preventing pruritis (itch) using natriuretic polypeptide b (Nppb) blocking agents. Itch (also known as pruritis) is a sensation that may be perceived as an unpleasant skin irritation and may drive an urge to scratch. Conditions such as, for example, psoriasis, atopic dermatitis, renal failure, liver cirrhosis and some cancers may cause persistent itch. Itch is triggered by somatosensory neurons expressing the ion channel TRPV1 (transient receptor potential cation channel subfamily V member 1).

mNFHcre Transgenic Mice

Knockout mouse is a valuable model to study biological functions of target genes. When Cre expressing mice are bred with mice containing a loxP-flanked gene, the gene between the loxP sites will be deleted in the offsprings. Scientists at the NIH have generated mNF-H-cre transgenic mouse lines that express Cre recombinase under the control of the promoter of the neurofilament-H gene, which is expressed in the late stage of neuronal maturation. The transgenic mice express cre in neurons (but not astrocytes) with highest expression in the cortex and hippocampus.

3D Bioprinting of Cardiac Patch with Anisotropic and Perfusable Architecture for the Repair of Damaged Cardiac Muscle

This technology includes a novel cardiac patch which was 3D printed to repair damaged cardiac tissue. Based on biological and anatomical understanding of myocardial tissue, a novel 3D bioprinting technique was developed to directly fabricate the cellularized and vascularized cardiac patch with anisotropic fiber and perfusable vessel architecture. The design will integrate biomimetic aligned myocardial fibers and perfusable blood vessels to create a thick, functional cardiac patch, suitable for the human heart implantation.

Monoclonal Antibodies for Detection of Stachybotrys chartarum (a Fungus)

CDC NIOSH researchers have developed a simple and rapid detection technique for Stachybotrys chartarum (a type of mold that commonly grows on wet building materials) by producing monoclonal antibodies which reacts with proteins in Stachybotrys chartarum. These antibodies can be used in immunologic detection assays to detect and possibly quantify Stachybotrys chartarum in environmental samples, and to our knowledge, they do not cross react with other fungi.

Nucleic Acid Detection of the Fungal Pathogen Histoplasma capsulatum from Clinical and Environmental Samples

This invention relates to detecting Histoplasma capsulatum by PCR using oligonucleotide probes specific for the fungus. Histoplasmosis is a mycotic infection of varying severity, usually localized in the lungs. Caused by H. capsulatum, infections are usually symptomatic but can develop into chronic disease, especially in immunocompromised individuals.

Diisocyanate Specific Monoclonal Antibodies for Occupational and Environmental Monitoring of Polyurethane Production Exposure-related Asthma and Allergy and Clinical Diagnosis

CDC researchers have developed monoclonal antibodies useful as diagnostics for diisocyanate (dNCO) exposure and for toxicity characterization of specific dNCOs. Currently, dNCOs are used in the production of all polyurethane products and are the most commonly reported cause of occupational-induced asthma and also linked to allergic contact dermatitis. Presumptive diagnosis of dNCO asthma is presently dependent on criteria such as work history, report of work-related asthma-like symptoms and nonspecific airway reactivity to methacholine challenge.

Non-radioactive, Miniature Bipolar Aerosol Particle Charger for Personal, Portable Instrumentation

This CDC developed invention is a novel device for a miniature, nonradioactive bipolar charger to electrically charge aerosol particles for use in personal and portable aerosol instrumentation. Such devices are an integral component of aerosol instruments employing electrical mobility-based techniques. Current, commercial state-of-the-art mobility instruments employ aerosol chargers using radioactivity to achieve bipolar particle charging and, therefore, are not suitable for field-portable instruments.

Cylindrical Handle Dynamometer for Improved Grip-Strength Measurement

CDC researchers have developed an improved dynamometer device and method for measuring maximum hand grip force or grip-strength. Human test subjects were used in conducting experiments to evaluate the handle and to assess the measurement method. In contrast to the currently used "Jamar handle" grip strength dynamometer devices, the cylindrical handle proved to be able to determine the overall grip strength for a subject, as well as show the grip force distribution around the circumference of the handle.

Physiologic Sampling Pump Capable of Rapidly Adapting to User Breathing Rate

This CDC developed physiologic sampling pump (PSP) overcomes shortcomings of previous devices by the use of calibrated valves in conjunction with a constant speed pump. This novel approach obviates typical PSP inertia that inherently limits system response, functionality and accuracy. All prior PSP designs have attempted to follow a user's breathing pattern by changing pump speed, thereby altering sampling rate. In that approach, pump inertia will limit system response and function due to the time required to adjust speed.
