Abstract: A method for quantifying in vivo ascorbate concentration in body fluids uses gas chromatography/mass spectrometry (GC/MS). Further provided is a method for measuring redox potentials of body fluid by determining the ratio of in vivo concentration of ascorbate to one or more of its metabolites.

Abstract: Subsurface regions of an X-ray transparent but optically opaque object are targeted along a visible line of sight obtained by the use of two radiation sources (an X-ray and light beam source, preferably a laser). The central ray from the X-ray source and the light beam are aligned using a calibration fixture, one to the other and both with respect to structures internal to the object being imaged to provide the visible line of sight. The system (method and apparatus) may be used in surgical applications for selective illumination and sighting to reach specific subsurface members of a patients anatomy by guiding an incision.

Abstract: A mechanized disc flaker for producing curled wood flakes having a rotatable disc plate, and one or more cutting knives mounted to the disc plate so as to provide for a slight "rake angle" defined in accordance with the invention as the angle made between the tool face and a plane perpendicular to the direction of tool travel. In a preferred embodiment, the apparatus includes rotatable and removable knife holders which permit the rake angle and the "cutting angle", defined in accordance with the invention as being the angle the cutting edge of the knife makes with the grain of the wood, to be modified to yield curled wood shavings having different geometries and characteristics. The preferred method of practicing the apparatus involves using a work piece having a certain moisture content which is directed against the work surface of the disc flaker using appropriate pressure all to provide for wood curls of desirable characteristics.

Abstract: Preservation of leukocytes by suspending in storage medium containing modified fluid gelatin, plasma, and a non-toxic buffer. Preferred additives include heterocyclic bases which occur in nucleic acids, or nucleosides or nucleotides containing the same.

Abstract: A method of reducing residual stresses in a fiber reinforced thermoplastic composite laminate having at least one free edge includes the step of heating a region adjacent the free edge using a platen for a time period sufficient to form a localized melt zone of the thermoplastic in the region. The heating step is however done under a sufficient pressure to prevent delamination of the laminate. After this is done, the region is cooled for a time period and under a pressure sufficient using a platen to solidify the region and to prevent the lamination thereof.

Abstract: Apparatus are set forth for particularly dehydrating products such as corn syrups, fruit and vegetable extracts, dairy products, or other temperature-sensitive or hard-to-handle products. The apparatus include using a pulse combustor to generate a hot, turbulent, gaseous environment in a dehydration chamber and spraying the feedstock into the chamber. As the feedstock droplets travel through the chamber, they are dehydrated and thereafter collected by suitable devices. Temperature and feedstock residence time in the chamber are controlled to prevent product degradation. Where the dehydrated product is hygroscopic, processing aids may be added to control hygroscopicity.

Abstract: The present invention provides novel inositol phosphate analogs and a method for their use for detecting the phosphatidylinositol cycle-dependent calcium of a cell.

Abstract: A subsurface sampler including a cylindrical casing with portholes to provide access below ground to sample potentially hazardous substances without contaminating investigative probes that are inserted into the interior cavity of the casing. The sampler has an inner sleeve that seals the portholes on the casing during the insertion operation. After the casing is inserted into the ground, the inner sleeve is rotated such that the windows on the sleeve and casing line up exposing the soil to a variety of investigative probes. A tab or wiper is attached to the inner sleeve to clear soil blocking the portholes in the casing and to cut through the "smear" zone immediately along side of the outer surface of the casing. Once the sampler casing is in the ground and portholes are open, a sampling probe is inserted into the interior cavity of the casing following a track or guide system.

Abstract: Antigenic surface proteins from the intraerythrocytic merozoite stage of Babesia bigemina have been isolated using cell fusions and monoclonal antibodies produced thereby. Immunization of mammals, such as bovines, with purified isolates induces an immunological response that is effective to reduce pathological effects of babesiosis induced by Babesia bigemina. Diagnostic kits using monoclonal antibodies and antigenic surface proteins of Babesia bigemina are also disclosed.

Abstract: The present invention relates to an adapter apparatus for medical endoscopes. The present invention comprises an apparatus for inserting tightly into a typical access port of a medical endoscope. Such adapter apparatus permits certain medical implements, such as optical fibers for laser surgery, to be inserted therethrough for treatment of the patient. This adapter apparatus also permits simultaneous passage therethrough of saline or other irrigation fluid without the prior removal of the medical implement. This permits rapid, simultaneous irrigation to proceed directly through an existing endoscope channel.

Abstract: A method of administering a liquid pharmaceutical formulation, particularly a surfactant formulation, to at least one lung of a subject in need of such treatment is disclosed. The method is carried out while the subject has a breathing tube extending through the subject's mouth and larynx, and while ventilating at least one lung of the subject through the breathing tube. The method comprises simultaneously administering the liquid pharmaceutical formulation down the breathing tube and into at least one lung of the subject and ventilating at least one lung of the subject through the breathing tube. The method may be performed on premature infants to combat respiratory distress syndrome.

Abstract: Substantially pure, non-toxic salts and esters of conjugated linoleic acid (CLA) are useful as antioxidants and as mold growth inhibitors. Methods of making the cis-9, trans-11 isomer of linoleic acid and the compounds are also disclosed.

Abstract: Several methods are disclosed for the preparation microporous alumina ceramic membranes. For the first time, porous alumina membranes are made which have mean pore sizes less than 100 Angstroms and substantially no pores larger than that size. The methods are based on improved sol-gel techniques.

Abstract: Micromechanical devices are formed on a substrate using a sacrificial layer deep X-ray lithography process to produce a rotating microrotor which is driven magnetically. The rotor typically has a diameter of a few hundred microns or less and is formed as a free structure which is assembled onto a hub formed on a substrate. Stator pole pieces are formed on the substrate of a ferromagnetic material surrounding the rotor, and are alThis invention was made with U.S. government support awarded by the National Science Foundationn (NSF), Grant #EET-88-15285. The U.S. government has certain rights in this invention.

Abstract: Therapeutic compositions are administered to the ocular tissues by positioning a balloon catheter having an illuminating fiberoptic stylette therein in the retrobulbar or parabulbar space of a patient. After the catheter is properly positioned, the composition is sequentially injected at predetermined intervals over a period of time. A variety of compositions can be administered including corticosteroids, antibiotics, macular degeneration alleviating compositions and inflammation alleviating compositions. Such administration of the therapeutic composition sustains appropriate levels of the composition in the ocular tissues without inducing toxic effects in unaffected tissues.

Abstract: A method and apparatus for detecting clot lysis, comprising allowing a blood sample containing a plasminogen activator to traverse a capillary track, wherein the capillary track contains a reagent capable of initiating blood clotting and the sample contacts the reagent as the sample flows through the track, the capillary track being of sufficient length and sufficiently small volume to allow blood to clot in the track before the sample reaches the end of the track and while a reserve sample volume remains available for continued capillary flow; allowing the sample to clot in the capillary track; and measuring time required for the sample to resume flowing as a measure of clot lysis.
