Method for Finding Usable Portion of Sigmoid Curve (the Taylor Method), Improved Assay Readouts, and Enhanced Quality Control/Assurance

CDC researchers have developed algorithmic methods for determining sigmoid curve optimums and calculating component concentrations. Sigmoid curves are commonly generated in bioassays and used to calculate results. Various techniques have been used to define the curve, analyze the observations, and calculate a concentration. This technology is an algorithmic approach to identifying the usable portion of a sigmoid curve.

Multi-Antigenic Peptide(s) Vaccine and Immunogen for Conferring Streptococcus pneumoniae Immunity

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.

Methods for Amelioration and Treatment of Pathogen-associated Inflammatory Response

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.

Human iPSC-Derived Mesodermal Precursor Cells and Differentiated Cells

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.

Rabbit Antisera to Various Matrix, Matricellular, and Other Secreted Proteins

The extracellular matrix (ECM) is composed of a group of proteins that regulate many cellular functions, such as cell shape, adhesion, migration, proliferation, and differentiation. Deregulation of ECM protein production or function contributes to many pathological conditions, including asthma, chronic obstructive pulmonary disease, arthrosclerosis, and cancer. Scientists at the NIH have developed antisera against various ECM components such as proteoglycan, sialoprotein, collagen, etc.. These antisera can be used as research tools to study the biology of extracellular matrix molecules.

Three-Dimensional Curved Catheter for Right Atrial Appendage Traversal

Available for licensing and commercial development is a three-dimensionally configured curved catheter for safe traversal of the right atrial appendage (RAA). The device is configured to optimize one-way access of the pericardial space through the right atrium and into the RAA reducing the risk of coronary lacerations. Specifically the curved catheter is best described in three segments: a proximal segment, a transitional segment and a distal segment; the transition segment having a clockwise spiral shaped curvature.

Inner Curvature Charge Concentration Device for Tissue Laceration

Left ventricular outflow tract obstruction is a life-threatening complication of transcatheter mitral valve replacement caused by septal displacement of the anterior mitral leaflet (AML). The AML is a mobile structure that physically separates inflow and outflow zones of the left ventricle. Preserving the AML during surgical mitral valve replacement can cause left ventricular outflow tract obstruction, either when the prosthesis struts protrude into the left ventricular outflow tract or when along redundant anterior leaflet prolapses into the left ventrical outflow tract.

Combination Therapy of Human Recombinant N-acetylgalactosamine-6-sulfate sulfatase (hrGALNS) and Chaperones for the Treatment of Mucopolysaccharidosis Type IVA

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.

Improved Cell Survival and Differentiation of Human Pluripotent Stem Cells by Combining Small Molecules Chroman-1 and Emricasan

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.

A Device to Measure Force Continuously During Handgrip Contraction and Relaxation for Myotonic Dystrophies

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.
