Disease caused by Streptococcus pneumoniae (pneumococcus) is an important cause of morbidity and mortality in the United States and developing countries. Pneumococcal disease is prevalent among the very young, the elderly and immunocompromised individuals. This invention is an improved, immunogenic peptide construct consisting of a combination of antigenic epitopes of the PsaA (37-kDa) protein from S. pneumoniae.

CDC researchers have developed a method of simultaneously detecting and distinguishing multiple antigens within a biological sample. Epidemiological and vaccine studies require species serotype identification. Current methods of serotyping are labor intensive and can easily give subjective, errant results. This technology utilizes serotype specific antibodies bound to fluorescent beads, allowing for simultaneous single tube capture and detection of multiple antigens in one rapid, high-throughput flow cytometry assay.

This CDC invention provides methods for preventing or treating inflammatory response-linked, infection induced pathologies, which are mediated by endogenous substance P. Substance P is a naturally-occurring and major pro-inflammatory neuromediator or neuromodulator, and elevated levels of substance P have been implicated in numerous inflammation-associated diseases. More specifically, this technology entails administration of anti-substance P antibodies or anti-substance P antibody fragments to a subject in need, thereby inhibiting the activity of endogenous substance P.

Cells, cell culture methods, and cell culture media compositions useful for producing and maintaining iPSC-derived cell lines that are of higher purity and maintain cell type integrity better than current iPSC-derived cell lines are disclosed. Human induced pluripotent stem cells (hiPSCs) can be generated by reprogramming somatic cells by the expression of four transcription factors. The hiPSCs exhibit similar properties to human embryonic stem cells, including the ability to self-renew and differentiate into all three embryonic germ layers: ectoderm, endoderm, or mesoderm.

Epstein-Barr Virus (EBV) is the causative agent of infectious mononucleosis and is associated with certain types of cancers, such as Hodgkin's lymphoma, Burkitt's lymphoma, gastric carcinoma, and nasopharyngeal carcinoma. There are currently no vaccines against EBV on the market and there is only supportive treatment available for EBV infection.

One of four deaths in the United States is due to cancer despite an emphasis on prevention, early detection, and treatment that has lowered cancer death rates by 20% in the past two decades. Further improvements in survival rates are likely to come from improving the limits of detection sensitivity at earlier stages of cancer. New approaches that rely heavily on genomic information, however, may change future testing strategies.

This technology includes the identification and use of a combination therapy consisting of human recombinant N-acetylgalactosamine-6-sulfate sulfatase (hrGALNS) and the pharmacological chaperone compounds Ezetimibe and Pranlukast for the treatment of Mucopolysaccharidosis Type IVA (MPS IVA). MPS IVA is a rare disease caused by mutations in the gene encoding the lysosomal enzyme N-acetylgalactosamine-6-sulfate sulfatase (GALNS). Currently, hematopoietic stem cell transplantation (HSCT) and enzyme replacement therapy (ERT) are available for patients with MPS IVA.

This technology includes the use of the combination of the compounds Chroman-1 and Emricasan to achieve virtually 100% cell survival during human pluripotent stem cell passaging, cryopreservation/thawing, and differentiation in 2D and 3D cultures. Human pluripotent stem cells, including ESCs and iPSCs, are highly sensitive cells and undergo apoptosis during these routine procedures. A screening approach was used to identify the combination of the two compounds in this invention.

This invention relates to two devices that reliably, sensitively, and accurately measures force during handgrip contraction and subsequent relaxation. A delayed relaxation after a sustained and forceful handgrip is a cardinal symptom of myotonic dystrophies (DM). This delayed relaxation, handgrip myotonia, may be a therapeutic response biomarker in clinical trials.

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.
