Abstract: The present invention provides terbium or lutetium garnet x ray scintillators activated with a rare earth metal ion, such as cerium, and treated by annealing in a controlled atmosphere comprising a predetermined amount of oxygen for a predetermined time and temperature to reduce radiation damage that would otherwise occur when the scintillator material is exposed to high energy radiation, such as the type of radiation required to use the scintillator for medical radiographic imaging and the like. In an embodiment, a single crystal or a polycrystalline scintillator comprising the general formula (Tb1−xLuxCey)3Al5O12 (where 0<×≦0.5, and y is in the range from about 0.0005 to about 0.2, and annealed at 1400° C. to 1500° C. in a controlled atmosphere comprising 1×10−6 to 0.22 atm oxygen shows an increased resistance to radiation damage.

Abstract: It has been determined that a specific metaplastic lineage that contains immunoreactivity for a trefoil polypeptide, spasmolytic peptide, is associated with and gives rise to the vast majority of human adenocarcinomas. The identification of this Spasmolytic Polypeptide Expressing Metaplasia (SPEM) is a major factor for grading of biopsies of the stomach to assess risk for gastric cancer. It also forms the basis of a method for serological screening for those at risk for gastric cancer. In a preferred embodiment, antibodies to spasmolytic peptide (hSP) are used in immunostaining of biopsies of gastric tissue obtained by endoscopy for grading biopsies. Those patients having these cells, characterized by a morphology more typical of a type of cell present normally in the intestine and not stomach, Brunner's gland cells, are at risk of developing adenocarcinoma.

Abstract: The invention consists of a flat panel display device that combines the simplicity of manufacture of a TFEL display with the phosphor stimulation capabilities of an FED. A phosphor such a ZnS:Mn can act as both an EL phosphor and as a cathodoluminescent phosphor. The phosphor is deposited on a porous silicon underlayer that contains a labyrinth of fissures, voids, hillocks, and microscopically rough surfaces. At the phosphor-porous silicon interface, the labyrinthine surface possesses hundreds to thousands of electric field line compression points that can be characterized by an average field enhancement. When this underlayer is the cathode, high energy electrons are injected into the phosphor producing substantial light emission even at low applied fields. Additionally, the surrounding silicon is available to integrate drive circuitry and provide a TFT at each pixel, if needed.

Abstract: A method for beneficially restructuring ingestible substances such as sports drinks, water, neutraceuticals, pharmaceuticals, and the like and its contents for consumption by organisms. The method is also applied to topical substances such as lotions and creams. The method involves subjecting such substances for a period of time to an electromagnetic field of a specified flux density varying from 10−5 to 10−21 gauss and a specific frequency varying from 0 hertz to 300 hertz, depending on the intended subsequent use of the substance. The specific flux density and the specific frequency is empirically determined to restructure the substances such that the substances beneficially affect the organism which has the substances incorporated into the organism's metabolism.

Abstract: A method and apparatus for treating infant plagiocephaly whereby a helmet encircles the upper cranium of an infant and prevents the infant from resting its head on flattened or depressed regions of the skull. The helmet contemplates an adjustable first member which encircles the infant's upper cranium, and a second member comprising a relatively rigid protruding element that is attached to the exterior surface of the first member. The second member is positioned so that it is superincumbant to flattened or depressed regions, so that when the helmet is worn, the second member forces the infant to rest its head on a different area of the skull, thus passively relieving pressure on the depressed skull, and applying a gentle active pressure to other areas. Additionally, the method an apparatus relates to the treatment of torticollis and other abnormalities of the neck.

Abstract: An automated weighing station is provided which is advantageous for automatically weighing samples generally disposed in containers in an array of racks. The weighing station comprises a sample handling assembly which is operably connected to a balance, allowing a moveable sample carrier to bring samples into position beneath the balance and sample handling assembly, thereby minimizing the movement of individual samples in order to accomplish weighing. A weighing system that provides flexibility and convenience in generating and transforming a variety of data sets associated with measurements accomplished using the weighing apparatus is also provided.

Abstract: A number of cDNA clones whose products may interact with D1 receptors in vivo were identified. One of the clones, P24, was characterized further. P24 is localized in dendrites and spines of pyramidal cells in PFC. The extent of overlap between P24 expressing and D1 receptor expressing pyramidal cells appeared to be 100%. In contrast, only a limited number D1 receptor antibody labeled neurons in caudate expressed P24. P24 lowers the threshold of D1 receptor response to dopamine (DA) by an order of magnitude. Sequence similarity suggests P24 is a diverged member of the RAMP family. The P24 protein is therefore referred to as a D1 DA RAMP, calcyon. The isolated protein and nucleotide molecule encoding the protein, as well as primers for the nucleotide, are described. The protein and compounds modifying DA binding to the receptor or calcium release which is mediated by the Calcyon, are useful in research studies, drug screening, and therapeutically.

Abstract: A welding method that enables the joining of at least two dissimilar, metallic alloys to form a weld that is free of cracks is disclosed. The method incorporates a pure (99.00% minimum by weight) nickel fill-wire, integrally assembled into the joint between the two alloyed metals to be joined. The alloys joined by this method are an iron-based, low expansivity, gamma-prime strengthened superalloy (i.e., Incoloy®) and a high carbon, powder metallurgical tool steel high in refractory metal alloying agents (i.e., CPM REX 20). Welding of the joint results in the formation of a nickel rich region within the weld, thus “inoculating” the weld against cracks. The weld joint formed by the method of the present invention can be used in the fabrication of a rotating anode bearing shaft assembly for use in an x-ray generating device.
