Near Real-time, Low-cost, Hand-held Sensors for Measuring Elemental Concentration of Airborne Particles for Indoor or Outdoor Air Quality Monitoring

Airborne particles can have great impact on air quality, weather, and human health. In particular, long-term inhalation of toxic particulate matter in workplaces could pose a significant health risk. NIOSH scientists have developed a new, low-cost approach based on application of atmospheric radio frequency glow discharge (rf-GD) optical emission spectroscopy for near real-time measurement of elemental concentration in aerosols. The method involves collection of aerosol particles on an electrode tip in a coaxial microelectrode system, followed by excitation of the particles using rf-GD.

Respirator Protection Devices and Methods to Detect and Remove Toxic Gases from the Air - Cobinamide Encapsulated Silica-based Materials for Respirator Canisters

A respirator protects the wearer from inhaling dangerous substances, such as chemicals and infectious particles. CDC developed devices and methods to detect and remove chemicals such as hydrogen cyanide, cyanogen, hydrogen sulfide, nitrite, and nitric oxide from the air for those wearing respirators. Cobinamide (a Vitamin B12 analog with a high affinity to cyanide) molecules are immobilized within a silica matrix that allows for the infiltration and containment of gaseous chemicals.

2-substituted Pyridines and Their Methods for Inhibiting BMP Signaling for the Treatment of Fibrodysplasia Ossificans Progressiva

This technology includes the use of a new class of molecules (nanomolar ALK2 inhibitor) to impede bone morphogenetic proteins (BMP) signaling for the treatment of Fibrodysplasia ossificans progressiva (FOP). FOP is a rare disease, characterized by malformation of the great (big) toes during embryonic development. Individuals with FOP have an identical heterozygous activating mutation (R206H) in the gene encoding ACRV1 (also known as ALK2), a BMP type 1 receptor.

Naphthalene-containing Selective Inhibitors of BMP type 1 Receptors for the Treatment of Fibrodysplasia Ossificans Progressiva

Pyrazolo[1,5-a]pyrimidine Derivatives as Selective ALK Kinases Inhibitors for Inhibition of the Bone Morphogenetic Proteins Signaling Pathway for Treatment of Fibrodysplasia Ossificans Progressiva

This technology includes compounds which are selective inhibitors of anaplastic lymphoma kinases (ALK1, ALK2, ALK3 and ALK6), which inhibit these ALKs with low nanomolar potency. These compounds could be developed as a treatment of Fibrodysplasia ossificans progressiva (FOP) and other BMP-related diseases. FOP is a rare congenital disease with no current treatment options. Since the disease is driven by constitutively active ALK2, inhibition of ALK2 would be like hitting the Achilles’ heel of the disease and would potentially be an efficacious therapy for FOP patients.

Peanut therapeutics and diagnostics to treat severe food allergies

Up to 10% of the US population suffers from food allergies, with more than 40% of those experiencing life-threatening anaphylaxis. Peanut is one of the most common food allergens that give rise to persistent IgE-mediated food allergy. Oral immunotherapy (OIT) is used to reduce sensitivity to an allergen through repeated, small-dose exposure to the allergen. However, only a subset of patients develop a sustained response to the allergen and OIT carries notable side effects.
