Abstract:
The present invention describes the isolation and characterization of multiple forms of human interferon- tau . Protein and nucleic acid coding sequences for the multiple forms are disclosed. In further aspects, the invention relates to methods of producing and using human interferon- tau molecules.
Abstract:
The subject invention pertains to novel Entomopoxvirus (EPV) polynucleotide sequences free from association with other viral sequences with which they are naturally associated, recombinant polynucleotide vectors containing the sequences, recombinant viruses containing the sequences, and host cells infected with the recombinant viruses are provided herein, as well as methods for use thereof in the expression of heterologous proteins in both insect and mammalian host cells.
Abstract:
The subject invention concerns novel peptides which have the property of interfering with the biosynthesis of the enzyme trypsin. This property enables the use of these peptides to, for example, inhibit the formation of progeny in blood-ingesting insects, since trypsin is an essential enzyme for food digestion which provides the essential building blocks for egg development in such insects.
Abstract:
The present invention describes the production of interferon- tau proteins and polypeptides derived therefrom. The antiviral and anticellular proliferation properties of these proteins and polypeptides are disclosed. One advantage of the proteins of the present invention is that they do not have cytotoxic side-effects when used to treat cells. Structure/function relationships for the interferon- tau protein are also described.
Abstract:
A method of enhancing the ionizing irradiation sterilization stability of an optically transparent, rigid, heat processible thermoplastic polymer comprising modifying the polymer to decrease the glass transition temperature thereof to a value such that: a) the glass transition temperature of the modified polymer is above the desired end-use temperature; b) the modified polymer remains optically transparent, rigid and heat processible; and c) the modified polymer recovers from the discolorization effects produced by exposure to ionizing sterilizing irradiation at a temperature below the glass transition temperature thereof.
Abstract:
A method for percutaneously fixing and fusing the lumbosacral joint and a guide device for accurate placement of instrumentation to effect the fixation or fusion. The inventive method comprises placement of pins along bony canals leading bilateral of the spine from the pelvis to the S1 pedicles and then the vertebral body of L5.
Abstract:
A method of preparing preceramic SiC fibers having a very low oxigen content by forming fibers from a solution of a polycarbosilane and vinylic SiC precursor in a mutual volatile solvent, heating fibers in an oxygen-free inert atmosphere to effect a cross-linking reaction therebetween. Also disclosed is a method of preparing SiC fibers having superior high temperature properties and a very low oxygen content comprising heating the above-described cross-linked preceramic fibers in an inert atmosphere substantially free of oxygen for a time and at a temperature sufficient to pyrolyze the cross-linked fibers to SiC fibers. The disclosure also describes the novel fibers produced by the above-described methods.
Abstract:
The subject invention pertains to a novel method for producing transgenic wheat plants. The transgenic plants are produced by delivering appropriate DNA to a specific callus type.
Abstract:
Recombinant host cells are obtained that comprise (A) a heterologous, polypeptide-encoding polynucleotide segment, stably integrated into a chromosome, which is under transcriptional control of an endogenous promoter and (B) a mutation that effects increased expression of the heterologous segment, resulting in enhanced production by the host cells of each polypeptide encoded by that segment, relative to production of each polypeptide by the host cells in the absence of the mutation. The increased expression thus achieved is retained in the absence of conditions that select for cells displaying such increased expression. When the integrated segment comprises, for example, ethanol-production genes from an efficient ethanol producer like Zymomonas mobilis, recombinant Escherichia coli and other enteric bacterial cells within the present invention are capable of converting a wide range of biomass-derived sugars efficiently to ethanol.
