Abstract:
The present invention is directed to methods and compositions relating to the treatment of herpes simplex virus infections and the screening of compounds for activity that inhibit or promote viral latency. The previously identified ORF P gene product now has been shown to interact with certain eukaryotic splicing factors and, in a cell infected with a herpesvirus containing a derepressed ORF P gene, ORF P can limit the splicing of at least two viral products. Given this function, it now is possible to screen for inhibitors and inducers of ORF P and, further, provide methods for maintaining and preventing viral latency.
Abstract:
This invention relates to uses of components of plant-like metabolic pathways not including psbA or PPi phosphofructokinase and not generally operative in animals or encoded by the plastid DNA, to develop compositions that interfere with Apicomplexan growth and survival. Components of the pathways include enzymes, transit peptides and nucleotide sequences encoding the enzymes and peptides, or promoters of these nucleotide sequences to which antibodies, antisense molecules and other inhibitors are directed. Diagnostic and therapeutic reagents and vaccines are developed based on the components and their inhibitors.
Abstract:
The present invention is directed to novel methods of enhancing the effectiveness of DNA damaging agents by exposing cells to viruses prior to or during exposure to the damaging agent. In certain embodiments of the invention, the DNA damaging agent is ionizing radiation, the virus is an adenovirus, and the increase in cell killing is synergistic when compared to radiation alone.
Abstract:
A solid/liquid process for the separation and recovery of chaotropic anions from an aqueous solution is disclosed. The solid support comprises separation particles having surface-bonded poly(ethylene glycol) groups, whereas the aqueous solution from which the chaotropic anions are separated contains a poly(ethylene glycol) liquid/liquid biphase-forming amount of a dissolved salt (lyotrope). A solid/liquid phase admixture of separation particles containing bound chaotropic anions in such an aqueous solution is also contemplated, as is a chromatography apparatus containing that solid/liquid phase admixture.
Abstract:
The present invention provides a process of increasing dopamine production in a cell comprising co-transfecting the cell with one or more expression vectors containing polynucleotides that encode tyrosine hydroxylase, aromatic L-amino acid decarboxylase and GTP cyclohydrolase. Cells transfected with such vectors and the use of such transformed cells to increase dopamine production in the central nervous system of animals are also provided.
Abstract:
The present invention relates to the signalling pathways connecting DNA damage, such as that induced by ionizing radiation or alkylating agents, and phosphorylation by tyrosine kinases.
Abstract:
A method and system for automated detection and classification of masses in mammograms. This method and system include the performance of iterative, multi-level gray level thresholding (202), followed by lesion extraction (203) and feature extraction techniques (205) for classifying true masses from false-postive masses and malignant masses from benign masses. The method and system provide improvements in the detection of masses including multi-gray-level thresholding (202) of the processed images to increase sensitivity and accurate region growing and feature analysis to increase specificity. Novel improvements in the classification of masses include a cumulative edge gradient orientation histogram analysis relative to the radial angle of the pixels in question; i.e. either around the margin of the mass or within or around the mass in question. The classification of the mass leads to a likelihood malignancy.
Abstract:
The invention relates generally to compositions of and methods for obtaining and using a polypeptide other than BCL-2 (SEQ ID NO.5) that affects programmed vertebrate cell death. The invention relates as well to polynucleotides encoding those polypeptides, recombinant vectors carrying those sequences, the recombinant host cells including either the sequences or vectors, and recombinant polypeptides. The invention further provides methods for using the isolated, recombinant polypeptides in assays designed to select and improve substances capable of altering programmed cell death for use in diagnostic, drug design and therapeutic applications.
