Portable Laser-Operated Counterfeit Drug Identifier (CoDI) for Tablets

Counterfeit drugs (also known as “fake or falsified medicines”) have become a major world-wide public health concern. Falsified medicines may contain toxic substances, the wrong active ingredients, suboptimal amounts of active ingredients, or no active ingredients at all. CDC researchers developed a portable (handheld), battery-operated, and relatively inexpensive device that non-trained personnel can use quickly to evaluate a particular branded tablet for authenticity.

Automated Microscopic Image Acquisition, Compositing and Display Software Developed for Applied Microscopy/Cytology Training and Analysis

Micro-Screen is a CDC developed software program designed to capture images and archive and display a compiled image(s) from a portion of a microscope slide in real time. This program allows for the re-creation of larger images that are constructed from individual microscopic fields captured in up to five focal planes and two magnifications. This program may be especially useful for the creation of data archives for diagnostic and teaching purposes and for tracking histological changes during disease progression.

Novel Primate T-cell Lymphotropic Viruses (HTLV, STLV) for Development of Diagnostics, Therapeutics, Research Tools, and Vaccines

CDC researchers have isolated and characterized the novel primate T-lymphotropic viruses denoted human T-lymphotropic viruses 3 and 4 (HTLV-3 and HTLV4), that are believed to have resulted from cross-species transmission at some point in the past. It has been previously established that HTLV-1 causes adult T cell leukemia and other inflammatory diseases; HTLV-2 is considered less pathogenic than HTLV-1 and has been associated with a neurologic disease similar to HTLV-1-associated myelopathy.

Select M. tuberculosis Peptides as Mucosal Vaccines Against Pulmonary Tuberculosis

This CDC-developed technology relates to novel vaccines or boosters directed against pulmonary tuberculosis. There is currently only a single vaccine against tuberculosis, the (Bacillus Calmette-Guérin) BCG vaccine. Reports suggest widely variable effectiveness for the BCG vaccine and that BCG administration has very limited success against prevention of the primary pulmonary form of the disease.

Molecular Detection and Viral-Load Quantification for HIV-1 Groups M, N and O, and Simian Immunodeficiency Virus-cpz (SIVcpz)

This invention provides materials, methods, and assays for detecting HIV-1 groups M and O and optionally HIV-1 group N and simian immunodeficiency virus-cpz (SIV-cpz). Specific nucleic acid primers for hybridization, amplification, and detection of HIV-1 are also provided for. The nucleic acid amplification assays can detect small concentrations of HIV-1 and are also useful for quantitative examinations of viral load concentrations within biological samples.

Simple, Rapid, and Sensitive Real-Time PCR Assays for Detecting Drug Resistance of HIV

This novel assay features real-time PCR reagents and methods for detecting drug-resistance related mutations in HIV, for newly diagnosed patients and those individuals currently receiving antiretroviral therapies. As the use of antiretroviral compounds to treat HIV infection proliferates, viruses adapt and evolve mutations limiting the efficacy of these drugs and disrupting the success of treatment.

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

Gene Therapy for Treatment of CRX-Autosomal Dominant Retinopathies

Mutations in the cone rod homeobox (CRX) transcription factor lead to distinct retinopathy phenotypes, including early-onset vision impairment in dominant Leber congenital amaurosis (LCA). Adeno-Associated virus (AAV) vector-mediated delivery of a CRX cDNA under the control of a CRX promoter region partially restored photoreceptor phenotype and expression of phototransduction genes in an in vitro model of CRX-LCA.

Methods and Compositions for Treating Genetically Linked Diseases of the Eye

X-linked retinoschisis (XLRS) is an inherited, monogenetic ocular disease caused by mutations in the retinoschisin (RS1) gene, resulting in the development of cystic cavities throughout the retina and leading to juvenile macular degeneration. Approximately 1:15,000 males in the US are affected, classifying the condition as an orphan indication.
