Title: Method and reagent composition for the determination of alanine aminotransferase and hbsag antigen in the same biological specimen
Inventor: FABRIZI PAOLO
IPC: G01N33/576
Filed: 1991-05-17
Abstract: ABSTRACT          The  enzyme  alanine  aminotransferase  (ALT)  is  colorimetrically determined  as  the  hydrogen peroxide  obtained  in  the  pyruvate hydrolysis reaction catalysed by the enzyme pyruvate  oxidase which develops  a  colour  read  at  550  nm  making  use  of  a  reagent composition buffered at pH comprised within 7.0 and 7.5  containing L-alanine,  ketoglutaric  acid, a source of inorganic  phosphorous, the  enzyme pyruvate  oxidase, a system for revealing the  hydrogen peroxide  and optionally one or more co-factors which  interact  in the enzymatic reaction catalysed by the enzyme pyruvate oxidase. It is moreover described a method for the determination of the  enzyme alanine aminotransferase making use of said reagent composition and of the surface antigen of the hepatitis B virus (HBsAg), by enzyme-immune assay, in the same serum specimen and in the same well of  a microtitration  plate.  The  method  is  particularly  useful   for checking  the  suitability of the blood intended  for  transfusions since it can be easily  carried out with equipments and instruments widely  used  for  the immunoenzymatic  screening  of  infectivity.          Furthermore it enables to test in the same analytical assay the two labels  of  hepatocyte  infections necessarily  researched  in  the transfusion centres on biological specimens and to select among the donors  the  most likely candidates to transmission  of  the   NANB hepatitis virus.

Title: Pen operated processing system with speed-responsive switching
Inventor: TANAKA HIDEKAZU
IPC: G06F3/038
Filed: 1991-06-05
Abstract: In an information processing system in which predetermined information is processed on the basis of coordinate data x, y, the coordinate data x, y is inputted through a coordinate inputting means such as a pen and tablet arrangement. Inputted loci are detected by sequentially accepting the coordinate data x, y. The processing mode of the information processing system is switched according to the configuration of the inputted loci. By switching the processing mode in response to the configuration of the inputted loci, the operation mode can be switched. For example, by moving the pen on the tablet in a jumped or reversed direction manner, the processing mode such as storing of a window can be effected.

Title: Receptor membranes and ionophore gating
Inventor: CORNELL BRUCE A
IPC: C07K17/08
Filed: 1990-01-29
Abstract: The present invention provides a membrane the conductivity of which is dependent on the presence or absence of an analyte.  The membrane comprises a closely packed array of self-assembling amphiphilic molecules and two ionophore components.  A receptor molecule reactive with the analyte is provided on one of the ionophore components.  The binding of the analyte to the receptor molecule causes a change in the relationship between the ionophore components such that the flow of ion across the membrane is prevented or allowed.  The ionophore components are preferably selected from the group consisting of amphotericin B, gramicidin A monomers and combinations thereof, with gramicidin A monomers being particularly preferred.  The present invention also provides a membrane including receptors directed against the Fc region of antibodies.  These receptors are preferably derived from polyclonal antibodies.  These membranes provide a "generic" surface which will bind antibodies in a manner such that the antigen binding regions of the antibody are not hindered.  The present invention further provides a device adapted for implantation in a mammalian body, the device being characterised in that it is coated with a membrane comprising a closely packed array of self-assembling amphiphilic molecules and receptor molecules.  The receptor molecules being such that the attachment of specific cells to the membrane is enhanced or avoided.  It is particularly preferred that the receptor molecules are directed against fibronectin, vitronectin, endothelial cells, or epithelial cells.  It is further preferred that the membrane coating the device also includes a plurality of ion channels such as gramicidin.

Title: General kernel function for electronic halftone generation
Inventor: RYLANDER RICHARD L
IPC: H04N1/405
Filed: 1991-09-13
Abstract: There is disclosed an algorithm for use with a digitized image which provides a means of simulating a continuous tone image containing a range of gray shades from black to white or a color separation. The "threshold equation" is the key of the invention as it calculates a threshold gray value that is compared to the desired local image value to determine whether that particular point should be "on" or "off". Which points (spots) are "on" and which are "off" is determined by the function that assigns a "threshold" value (the shade at which a pixel changes from "off" to "on") based on a pixels "x" and "y" coordinates.

Title: Steroid eluting cuff electrode for peripheral nerve stimulation
Inventor: LEE PHILIP
IPC: A61B5/296
Filed: 1991-02-06
Abstract: An electrode for establishing electrical contact with a nerve of a patient has an outer cuff (15) of an insulating material which is sutured around the nerve to be contacted. A drug impregnated layer (16) of material is positioned inside of the outer cuff.  This material is a polymeric matrix which permits the drug to leach out at a predetermined rate. The drug is a steroid such as dexamethasone sodium phosphate. The actual electrical contact is produced by metallic foil (12, 13) which is positioned on the surface of the drug impregnated layer of material which is located inside of the cuff. An insulated lead (9) electrically couples the metallic foil to an electronic circuit located remote from the nerve.  The leaching out of the drug serves to control irritation, swelling and impedance of the nerve/electrode interface.
