Field-Adapted Spot Test for Evaluating Materials Treated with Permethrin Insect Repellent

Military uniforms and mosquito nets are treated with permethrin, a repellent and insecticide used for personal protection against biting flies, mosquitoes, and other disease-carrying insects. Vector-borne diseases such as malaria, leishmaniasis (a parasitic infection spread by sandflies), Zika virus, West Nile virus, Lyme disease, and more can be diminished if treated nets or clothing containing the proper amount of permethrin are utilized. Washing and wear depletes the insecticide on the material, eventually rendering it ineffective.

A Device for Simultaneous and Rapid Diagnosis and Detection of Recent and Long Term HIV-1 Infection

CDC scientists have developed a device for simultaneous rapid diagnosis of HIV infection and for identification of recent HIV-1 infection. The device utilizes immunochromatographic or flow-through principles to detect HIV antibodies within clinical samples. This device may be used for diagnosis of HIV infection, as well as to distinguish between recent infection (6 months) and long-term infection (>1 year).

Multiplexing Homocysteine in Primary Newborn Screening Assays Using Maleimides as Select Derivatization Agents

Homocystinuria (HCU), a group of inherited disorders, causes symptoms ranging from failure to thrive and developmental delays in infants or young children to abnormal blood clots with onset in adults.1 Approximately 1 in 200,000 to 335,000 people have HCU globally.2

Anti-Puromycin Antibodies Illuminate the World of Cellular Protein Translation

The Ribopuromycylation (RPM) technology, developed by Dr. Jon Yewdell and Dr. Alexandre David, offers a powerful and universal method for visualizing and studying protein translation within cells. RPM involves the use of puromycin, a molecule that mimics a tyrosyl-tRNA and terminates translation by becoming covalently incorporated into the nascent protein chain's C-terminus within the ribosome's A site. This technique enables the immobilization of puromycylated nascent protein chains on ribosomes when chain elongation inhibitors like cycloheximide or emetine are utilized.

Recombinant Sulfated HIV Envelope Protein and Methods for Making Protein

This technology comprises sulfated recombinant gp120 proteins and peptides. Also included are methods for producing sulfated recombinant gp120 proteins. The focus of this technology is on sulfation of two tyrosines in the V2 loop of the HIV major envelope glycoprotein, gp120, which increase the stability of gp120 and promote the synthesis of gp120 protein in its native "closed" conformation. Gp120 in its native form is highly sulfated; however, recombinant gp120 produced for vaccines or structural analyses typically display low levels of V2 tyrosine sulfation.

Multichannel Individualized Seizure Therapy (MIST) Device

The Multichannel Individualized Stimulation Therapy (MIST) device is a multichannel electrical stimulation system that can be used for targeted, individualized electroconvulsive therapy (ECT), especially for treatment-resistant depression (TRD). Millions of individuals suffer from TRD, for which ECT is often the most efficacious and rapidly acting treatment option.

Robotic Exoskeleton for Treatment of Crouch Gait in Children with Cerebral Palsy (CP)

Crouch gait is a common disorder in pediatric cerebral palsy (CP). Effective treatment of crouch during childhood is critical to maintain mobility into adulthood. Current interventions do not alleviate crouch gait long-term for most patients. This technology relates to a powered exoskeleton designed for gait assistance. The powered assistance may provide a physical therapy-type intervention to improve and maintain mobility.  

Learning to Read Chest X-Rays: Recurrent Neural Cascade Model for Automated Image Annotation

Medical image datasets are an important clinical resource. Effectively referencing patient images against similar related images and case histories can inform and produce better treatment outcomes. Labeling and identifying disease features and relations between images within a large image database has not been a task capable of automation. Rather, it is a task that must be performed by highly trained clinicians who can identify and label the medically meaningful image features.
