Abstract:
Compositions and methods for down modulating expression of target nucleic acids using a single strand oligoribonucleotide siRNA compound are disclosed.
Abstract:
Disclosed are embodiments of methods, systems, and apparatus for providing multiple image fields or regions on an imaging array. In certain preferred embodiments, a high density imaging array may be partitioned into two or more regions, each of which may be used to render a separate view of the scan volume. This arrangement may provide an increase in the effective scan volume beyond the volume available with a single imager having a single point of view and may allow for reading of encoded symbols at a variety of orientations that would otherwise preclude accurate imaging with a single imager.
Abstract:
A method aligns a second image of an object taken at a second time with a first image taken at a first time, wherein the object experiences motion relative to an imager between the first and second times. The images are formed of sets of pixels arranged horizontally and vertically in a pattern. The method operates on the pixels of the second image by performing a series of operations to affect an affine transformation without performing matrix arithmetic, preferably by table look-up. The method shifts the pixels of the second image vertically by a constant vertical offset, shifts the pixels of the second image horizontally by a constant horizontal offset, shears the second image horizontally by a skew factor, shears the second image vertically by a skew factor, scales the second image horizontally by a horizontal scale factor; and scale the second image vertically by a vertical scale factor.
Abstract:
Covalently reactive antigen analogs are disclosed herein. The antigens of the invention may be used to stimulate production of catalytic antibodies specific for predetermined antigens associated with particular medical disorders. The antigen analogs may also be used to permanently inactivate endogenously produced catalytic antibodies produced in certain autoimmune diseases as well as in certain lymphoproliferative disorders. Also provided are methods for modulating the efficacy of nucleic acid based therapeutics.
Abstract:
The present invention provides novel compositions and methods useful in cancer therapy for inhibiting the multidrug resistance phenotype, which often thwarts long-term chemotherapeutic regimens. The novel compositions of matter comprise oligonucleotides targeted to the human MDR1 and MRP genes, which inhibit expression of these genes, thereby rendering tumors and other forms of cancer more susceptible to the cytotoxic effects of chemotherapeutic agents. Oligonucleotides are also provided that inhibit the multidrug resistance phenotype by exerting an aptameric effect.
Abstract:
A signal synthesizer system allowing a wide variety of signal sources for test and evaluation is provided. In one embodiment, the signal synthesizer system is a phase calibration system resulting in a wideband, variable phase two channel synthesized source with good phase accuracy over its entire frequency range.
Abstract:
A signal synthesizer system allowing a wide variety of signal sources for test and evaluation is provided. In one embodiment, the signal synthesizer system is a precision two channel synthesizer having a variety of capabilities which are made possible by having two independently controlled sources with a common controller residing in one instrument.
Abstract:
Compositions and method for down modulating target gene expression which RNA interference, as well as methods for administering said compositions are disclosed. The method comprises administering a first oligonucleotide strand to a cell, incubating the cells for a time period suitable for uptake of the first oligo nucleotide strand prior to administration of a second oligonucleotide strand, wherein the first strand and the second strand form an intracellular duplex which is effective to catalyze degradation of gene target mRNA or inhibit translation of said mRNA.
