Abstract:
Compounds according to Formula (I), Formula (II), Formula (III), Formula (V), Formula (VI), or to Formula (VII), and pharmaceutical compositions of compounds that conform to Formula (IV) or (Formula VIII): where R 1 through R 33 are prescribed, selectively inhibit P. falciparum dihydroorotate dehydrogenase. Accordingly, a method for preventing and treating malaria attaches to such compounds, as well as to pharmaceutically acceptable salts, solvates, stereoisomers, tautomers, and prodrugs thereof.
Abstract:
The present invention provides a method of diagnosing a Chlamydia infection in a subject, comprising contacting a sample from the subject with a substrate of chlamydial protease/proteasome-like activity factor (CPAF) under conditions whereby cleavage of the substrate can occur; and b) detecting cleavage of the substrate, thereby diagnosing a Chlamydia infection in the subject.
Abstract:
This invention generally relates to use of novel nanomaterials comprised of metals in anti-viral applications. Such nanomaterials, for example, can be produced using a high power, pulsed plasma process, which plasma process, optionally, can be performed on the metal with a precursor (i.e., a gaseous precursor, such as acetylene or methane) when forming the unagglomerated nanomaterials. In embodiments of the invention, the metal is nanosilver. Optionally, the nanomaterials may also comprise carbon, including in the form of carbyne.
Abstract:
The present invention provides a nucleic acid comprising a) a nucleotide sequence encoding one or more pro-apoptotic proteins, and b) a nucleotide sequence encoding one or more tumor-specific and/or tissue-specific promoters. Also provided is a method of treating cancer, comprising administering the compositions of this invention to a subject.
Abstract:
The present invention provides a composition comprising a chimeric polypeptide comprising a recall antigen that reactivates memory T cells in a subject and a new antigen that activates naïve B cells in a subject and a composition comprising a nucleic acid encoding a chimeric polypeptide comprising a recall antigen that reactivates memory T cells in a subject and a new antigen that activates naïve B cells in a subject. Further provided are methods of eliciting an immune response, as well as treating and/or preventing disease in subjects in whom the ability to mount an immune response to a new antigen is impaired, by administering the compositions of this invention.
Abstract:
The present invention provides cells comprising an isolated nucleic acid encoding a novel lactate dehydrogenase (LDH) and/or the encoded LDH polypeptide. The invention further provides cells comprising an isolated nucleic acid encoding LDH, wherein the cell is capable of producing and secreting insulin. Also provided are methods of providing fuel-stimulated (e.g., glucose-stimulated) insulin secreting capability to a mammalian subject by implanting cells of the invention (e.g., in a semi-permeable membrane and/or an implantable device) into the subject. Further provided are devices comprising the cells of the invention. In particular embodiments, the device is an implantable device.
Abstract:
The present invention includes methods for producing nanocrystals of semiconductor material that have specific crystallographic features such as phase and alignment by using a self-assembling biological molecule that has been modified to possess an amino acid oligomer that is capable of specific binding to semi-conductor material. One form of the present invention is a method to construct ordered nanoparticles within the liquid crystal of the self-assembling biological molecule.
Abstract:
This application describes intracellular, cytoplasmic molecules that are translocated to the surface of a microorganism and participate in binding the microorganism to the surface of a host cell. Examples of such translocated molecules include glycerahdehyde 3-phosphate dehydrogenase, pyruvate dehydrogenase, and elongation factor-Tu. Regions oftranslocated molecules important for binding, as well as molecules which disrupt binding, are described. Antibodies directed to translocated molecules are also described.
Abstract:
A method for the production of a robust, chemically stable, crystalline, passivated nanoparticle and composition containing the same, that emit light with high efficiencies and size-tunable and excitation energy tunable color. The methods include the thermal degradation of a precursor molecule in the presence of a capping agent at high temperature and elevated pressure. A particular composition prepared by the methods is a passivated silicon nanoparticle composition displaying discrete optical transitions.
Abstract:
The process of detecting RNA molecules in situ using the 3SR amplification process, for example where the molecules are translocation-junction-spanning molecules in cells that have undergone chromosomal translocation. Also process modifications that enhance its effectiveness.
