Abstract:
DNA sequences associated with regulation of early stages of cell growth are described. Illustratively provided are human and mouse origin DNA sequence encoding early growth regulatory (''Egr'') proteins which include ''zinc finger'' regions of the type involved in DNA binding. Immunological methods and materials for detection of Egr proteins and hybridization methods and materials for detection and quantification of Egr protein related nucleic acids are also disclosed.
Abstract:
Disclosed are novel immunochemical reagents including non-neurotoxic peptides having amino acid sequence homology to residues 254 to 280 of the gp120 glycoprotein of HIV-IIIB and antibodies thereto that are capable of in vitro inhibition of HIV-1 infectivity. The peptides and antibodies are useful in diagnostic assays and as active components of vaccine compositions for active and passive vaccination procedures.
Abstract:
Disclosed is a smooth muscle cell specific promoter, the SM22 alpha gene promoter as well as the murine cDNA and genomic SM22 alpha nucleic acid sequences. Also disclosed are methods of preventing restenosis following balloon angioplasty and methods of treating asthma based on inhibition of smooth muscle cell proliferation by expressing cell cycle control genes, or contraction inhibiting peptides in smooth muscle cells, under the control of the SM22 alpha promoter.
Abstract:
The ICP4 protein of herpes simplex virus plays an important role in the transactivation of viral genes. The present invention discloses that ICP4 also has the ability to inhibit apoptosis. This function appears to reside in functional domain distinct from the transactivating function, as indicated by studies using temperature sensitive mutants of ICP4 that transactivating function at elevated temperatures. Also disclosed are methods for inhibition of apoptosis using ICP4 or an ICP4 encoding gene, such as an alpha 4 gene, methods of inhibiting ICP4's apoptosis-inhibiting function, and methods for the production of recombinant proteins and treatment of HSV infections.
Abstract:
Methods for restablishing normal sleep patterns in adults with age-related sleep disorders are provided. In particular, methods are disclosed wherein a compound that stimulates growth hormone and/or prolactin secretion is orally administered to subjects just prior to retiring.
Abstract:
Ultralow friction properties available through the annealation and subsequent cooling of various boron-containing substrates, articles and/or components.
Abstract:
A method and system (110) for monitoring both an industrial process and a sensor (104). The method and system include determining a minimum number of sensor pairs needed to test the industrial process as well as the sensor (104) for evaluating the state of operation of both. After obtaining two signals associated with one physical variable, a difference function is obtained by determining the arithmetic difference between the pair of signals over time. A frequency domain transformation is made of the difference function to obtain Fourier modes describing a composite function. A residual function is obtained by subtracting the composite function from the difference function and the residual function (free of nonwhite noise) is analyzed by a statistical probability ratio test.
Abstract:
Methods for the identification of inducers and inhibitors of apoptosis are described. The method exploits the finding that the exposure of cells to apoptotic stress and its concurrent shutdown of cellular protein synthesis is accompanied by phosphorylation of IF-2 alpha and a novel protein termed p90.
Abstract:
A method and system for performing surveillance of transient signals of an industrial device to ascertain the operating state. The method and system involves the steps of reading into a memory training data, determining neural network weighting values until achieving target outputs close to the neural network output. If the target outputs are inadequate, wavelet parameters are determined to yield neural network outputs close to the desired set of target outputs and then providing signals characteristic of an industrial process and comparing the neural network output to the industrial process signals to evaluate the operating state of the industrial process.
Abstract:
A nonimaging concentrator (50) of light. The concentrator has a shape defined by dR/dphi=Rtanalpha, where R is a radius vector from an origin to a point of reflection of a light edge ray (70) from a reflector surface (90) and phi is an angle between the R vector and an exit aperture (80) of the concentrator and coordinates (R, phi) represent a point on the reflector surface and alpha is an angle the light edge ray from an origin point makes with a normal to the reflector surface.
