Abstract:
A low-cost fabrication technique, readily extensible to volume manufacturing is presented for an electro-optically active fiber segment (31) that can be simply integrated into optoelectronic devices. The fabrication technique offers a dielectric isolation structure (16, 17) surrounding the fiber (10) to allow high field poling, a pair of electrodes (37, 38) used both for poling and for inducing an electro-optic effect, and ends of the fiber (18, 19) unaffected by the fabrication and available for splicing with additional fiber sections. The technique is readily adaptable to specialized electrode structures including striplines and/or microstrip lines for high frequency applications and segmented electrodes (52) for quasi-phasematched three-wave mixing applications. By combining the electro-optically active fiber segment (31) with other fibers in an integrated fiber modulator, high frequency modulation of an optical signal may be achieved with applications in telecommunications. By including a Bragg grating structure (53, 54) in the same fiber segment, a remotely accessible electric field sensor is achieved. Three-wave mixing processes in the electro-optically active fiber segment (31) will allow the generation of additional coherent radiation sources in both the visible/UV and infrared spectral ranges.
Abstract:
A displacement method and device in which speckle amplitude interferometry within a single speckle feature or a small number of features of a speckle pattern is used to achieve sub-fringe accuracy with a single detector and to measure displacement of the object (3) under investigation with sub-wavelength accuracy at measurement speeds consistent with real-time control of manufacturing processes. The same technique applied to multiple spots on a sample (3) with optical means for causing interference between different combinations of scattered fields, for example beams (4) and (14) interfere and beams (5) and (15) interfere, including fields (4 or 5 and 14 or 15) from different illumination spots, permits measurements of the total sample (3) motion.
Abstract:
The present invention provides isolated DNA molecules comprising a DNA segment encoding novel human Kunitz-type inhibitors. Also provided are DNA constructs comprising a first DNA segment encoding a novel human Kunitz-type inhibitor wherein said first DNA segment is operably linked to additional DNA segments required for the expression for the first DNA segment, as well as host cells containing such DNA constructs and methods for producing proteins from the host cells.
Abstract:
Components of the primary amino acid sequence of a metallothionein are genetically incorporated into proteins by recombinant DNA techniques to produce a hybrid molecule comprising an effector protein continuous with the metallothionein. The sulfhydryl and lysine residues of the metallothionein portion of the hybrid molecule provide binding sites for ligands such as radionuclides, contrast agents, magnetic resonance agents, fluorochromes, and enzymes. The labeled hybrid molecule is useful for the diagnosis and localization of disease lesions and is a cost-effective method of producing key ingredients for immunoassays including immunosorbant assay, immunoblot, immunodot, immunohistochemistry, and/or flow cytometry.

Abstract:
The invention provides a method for the diagnosis and treatment of neurological diseases or disorders characterized by disruption of the blood/brain barrier. The 92 kDa zymogen of gelatinase B and active gelatinase B are markers of neuropathologies associated with disruption of the blood/brain barrier.
Abstract:
This invention is a reusable, miniature, implantable electrochemical sensor, a method of making the same, and a powder therefor that is provided. Enzyme material (53) is immobilized on bulk particulate matter, and a reaction chamber (23) of the sensor (10) is then filled therewith. The sensor (10) is implanted in an environment where it comes into contact with a specific component of a fluid with which the enzyme material chemically reacts to produce electrical signals for measuring the reaction.
Abstract:
This invention provides an extremely porous xerogel dried at vacuum to below-supercritical pressures but having the properties of aerogels which are typically dried at supercritical pressures. This is done by reacting the internal pore surface of the wet gel (e.g. alkoxide-derived silica gel) with an organic surface modification agent (e.g. trimethylchloro-silane in benzene) in order to change the contact angle of the fluid meniscus in the pores during drying. Shrinkage of the gel (which is normally prevented by the use of high autoclave pressures, such that the pore fluid is at temperature and pressure above its critical value) is avoided even at vacuum or ambient pressures. The figure 4 shows a change in sample weight and sample length during drying for surface modified, ambient pressure gel processed in accordance with the invention, illustrating the initial shrinkage followed by expansion of the gel during the final stages of drying. The extremely low density finely pored gel products have useful insulating and other properties.
Abstract:
An exercise regimen which enhances exercise endurance and performance. The regimen includes pre-exercise hydration with a glycerol solution combined with hydration during exercise with a glycerol based solution to prolong hydration effects. The first pre-exercise glycerol solution regimen begins 2 hours prior to exercise and ends 1/2 hour before exercise begins. The hydration during exercise regimen combines glycerol with a carbohydrate and sodium to prolong fluid retention.
