Abstract:
Diamond microtip field emitters (25) are fabricated for use in diode and triode vacuum microelectronic devices, sensors and displays. Ultra-sharp emitter tips are formed in a fabrication process in which diamond is deposited into mold cavities in a two step deposition sequence. During deposition of the diamond, the graphite content is carefully controlled to enhance emission performance. The tips or the emitters (25) may be treated by post fabrication processes, such as sharpening or doping with gold.

Abstract:
The present invention provides novel methods for gene delivery and expression in areas that are currently inaccessible through the use of conventional direct protein delivery techniques. In particular, the methods and related products provided herein can be used in the treatment of alpha 1 antitrypsin (AAT) related disorders such as respiratory syncytial virus (RSV) infection.
Abstract:
The present invention provides a yeast cell comprising a nucleic acid functionally encoding a eukaryotic (e.g., mammalian) protein homologue of a subunit (Sec11p, Spc1p, Spc2p and/or Spc3p) of the yeast signal peptidase complex. The yeast cell of this invention can be, for example, of the genus Saccharomyces, Schizosaccharomyces, Pichia, Hansenula, Kluyveromyces and/or Yarrowia. Furthermore, the yeast cell can lack one or more functional subunits (Sec11p, Spc1p, Spc2p and/or Spc3p) of the yeast signal peptidase complex. The present invention further provides a method for producing a protein heterologous to a yeast cell comprising expressing, in the yeast cell of this invention, a nucleic acid functionally encoding the heterologous protein under conditions which permit the expression of the nucleic acid as a precursor protein having a signal peptide and processing of the precursor protein to a signal peptide-cleaved form of the protein. A method is also provided for obtaining increased production of a protein heterologous to a yeast cell comprising expressing, in the yeast cell of this invention, a nucleic acid functionally encoding the heterologous protein under conditions which permit the expression of the nucleic acid as a precursor protein having a signal peptide and processing of the precursor protein to a signal peptide-cleaved form of the protein. Additionally provided is a method for producing a yeast cell capable of increased production of a protein heterologous to the yeast cell, comprising introducing into the yeast cell (with or without one or more functional SPC subunits) a nucleic acid which functionally encodes one or more eukaryotic protein homologues of the signal peptidase complex under conditions permitting the expression of the nucleic acid as the protein homologues.
Abstract:
The present invention provides a unique approach for the diagnosis and management of infections by Chlamydia species, particularly C. pneumoniae. The invention is based, in part, upon the discovery that a combination of agents directed toward the various stages of the chlamydial life cycle is effective in substantially reducing infection. Products comprising combination of antichlamydial agents, novel compositions and pharmaceutical packs are also described.
Abstract:
The present invention provides methods of identifying cellular genes necessary for viral growth and cellular genes that function as tumor suppressors. Thus, the present invention provides nucleic acids related to and methods of reducing or preventing viral infection or cancer. The invention also provides methods of producing substantially virus-free cell cultures and methods for screening for additional such genes.
Abstract:
Purified BMP-15-related proteins and processes for producing them are disclosed. DNA molecules encoding the BMP-15-related proteins are also disclosed. The proteins may be used in the treatment of bone and cartilage and/or other connective tissue defects and in wound healing and related tissue repair.
Abstract:
The present invention concerns composition, kits and methods for reducing the flushing effect (cutaneous erythema) of an antilipemic drug, for treating hyperlipemia, for improving the effectiveness of an anti-platelet aggregating drug (e.g., in nonresponders) and for treating thrombosis. The present compositions and kits for reducing the flushing effect and for treating hyperlipemia contain an antilipemic drug such as niacin and either a sustained-release NSAID (such as aspirin) or an NSAID and a carboxylic acid compound other than the NSAID and antilipemic drug. The kits contain (a) predosages of the NSAID and optional carboxylic acid compound and (b) an antilipemic dosage of the antilipemic drug, which optionally may be combined with NSAID and optional carboxylic acid compound in an amount effective to maintain the reduction of the flushing effect. The present method of treating hyperlipemia comprises predosing the patient with a sustained-release NSAID or an NSAID and a carboxylic acid compound other than the NSAID and antilipemic drug at least 2 hours before administering the antilipemic drug. The present compositions and kits for increasing the effectiveness of an antiplatelet aggregating drug contain an NSAID such as aspirin, niacin or a congener thereof, and optionally, a carboxylic acid other than the NSAID niacin, such as citric acid.
Abstract:
This invention provides compounds of formula (I), wherein R , R , and R are independently a first halogen atom, alkyl, alkenyl, alkynyl, alkoxy, alkenoxy, or alkynoxy, wherein R and R can also independently be H, wherein at least one of R , R , and R is a second halogen atom or is substituted with a second halogen atom; R is H or lower alkyl; and R is H or NH2; with the proviso that when R is NH2, R is not H, and when R , R , and R are H, R is not H. The invention also provides precursors of formula (I), radioactive analogs of formula (I), and methods of using the compounds for the identification of 5-HT-3 receptors and the detection and treatment of abnormal conditions associated therewith.
