Improved Acoustic Plethysmograph System for Noninvasive Measurement of Pulmonary Function

CDC researchers have developed a novel acoustic whole body plethysmograph (AWBP) that allows measurement of tidal volume in lab animals, independent of gas compression in the lung. This system provides particular advantages over the traditional whole body plethysmograph (WBP) when measuring model animals with increased gas compression due to increased airway resistance or increased acceleration in the breathing pattern.

Hearing Safety Devices: System for Monitoring Exposure to Impulse Noise

This CDC-developed technology entails a system for monitoring and assessing the risk of auditory damage from exposure to impulse noise, such as noise created by construction machinery and firearms. Noise dosimeters have been used extensively over the past two decades to document personal exposure to noise and assure workplaces comply with permissible noise exposure levels. However, due to older methods of calculating "noise dose," current noise dosimeters often inaccurately determine the risk of an impulse event.

Occupational Health: Wearable Kneel-Sit Support Device for Manual Labor and Heavy Industry Applications

This CDC-developed technology describes a novel ergonomic device that supports a portion of the worker's weight while kneeling, relieving the knee pressure and pain common to many manual labor occupations. Unfortunately, many of the devices that have been used in the past to relieve pressure on the knees are bulky, heavy, and of questionable durability.

Direct Reading Detection Kits for Surface Contamination by Anti-Neoplastic (Anti-Cancer) Drugs

Anti-neoplastic drugs, also known as anti-cancer drugs or chemotherapy, are used in the treatment of many types of cancer. However, these drugs are harmful to healthy cells as well as the cancerous cells. Exposure of healthcare workers to anti-neoplastic drugs from contaminated surfaces and drug vials in hospitals and pharmacies is a continuing problem as the drugs can cause both acute and long-term effects. Although there are sensitive techniques to evaluate contamination, results from these tests take time and must be performed in a laboratory.

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.

Handwipe Disclosing Method for Detecting the Presence of Lead

Lead (Pb) exposure can cause serious health concerns including abdominal pain, headaches, loss of appetite, memory loss, weakness, and other symptoms. Lead residues on human skin, especially on the hands of workers can be a significant health risk since such residues may be ingested during normal activities (e.g. eating, drinking, and smoking). A key component to reducing lead exposure is being able to identify areas of lead contamination.

Monoclonal Antibodies That Bind to the Underside of Influenza Viral Neuraminidase

Current influenza vaccines mainly induce antibodies against the surface glycoprotein hemagglutinin (HA) that block viral attachment to its host receptors and viral membrane fusion to the host cell. The immunodominant head region of HA undergoes antigenic drift and antibodies directed to the head confer little cross-protections between strains or subtypes.

Neutralizing Antibodies to Influenza HA and Their Use and Identification

The effectiveness of current influenza vaccines varies by strain and season, in part because influenza viruses continuously evolve to evade human immune responses. While the majority of seasonal influenza infections cause relatively mild symptoms, each year influenza virus infections result in over 500,000 hospitalizations in the United States and Europe. Current standard of care for individuals hospitalized with uncomplicated influenza infection is administration of neuraminidase inhibitors.

Programmable and Modular Nucleic Acid Nanoassemblies-based (NAN) Platforms to Regulate Mechanosensitive Activation of T-cells

This technology includes mechanobiological nucleic acid nanoassemblies-based platforms with dynamically controlled efficiency of T-cell activation. T-cells are the central players in adaptive immune response led by a T-cell receptor (TCR) centric machinery. Current T-cell activation strategy (e.g., micron-scale beads) focuses on 2D TCR-agonist biomimetic surfaces and biomimetic 2D immune synapses with planar traction, which requires non-physiological hyper-stimulatory cytokines levels (e.g., IL-2), and thus, is incompatible with clinical applications.

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.
