Abstract: An actuator and a method of controlling the actuator are disclosed. In one embodiment, the actuator is a valve comprising a first port and a second port fluidly connected with the first port such that fluid communicates between the first port and the second port. A flexible member is operatively connected with the first port and the second port. The flexible member is movable between a first position permitting fluid communication between the first port and the second port and a second position reducing fluid communication between the first port and the second port. A first controller is operatively connected with the flexible member for moving the flexible member between the first position and the second position. A second controller is operatively connected with the flexible member for retaining the flexible member in the second position.
Abstract: Methods of fluid handling are disclosed. In one method, a nozzle is moved adjacent a container for a fluid. A pump fluidly associated with the nozzle is energized to move fluid with respect to the nozzle. A pressure transducer fluidly associated with the nozzle is energized to monitor transient pressure fluidly associated with the nozzle. The transient pressure fluidly associated with the nozzle is substantially continuously monitored with the pressure transducer at least during operation of the pump. It is determined whether movement of fluid with respect to the nozzle is intended or unintended based on the substantially continuously monitored pressure fluidly associated with the nozzle.
Abstract: This invention relates generally to an assay for Lyme disease which detects the antibody to Borrelia burgdorferi, the causative agent of Lyme disease. More specifically, the assay employs antigens derived from amino acid regions in the flagellum of Borrelia burgdorferi. These antigens are immunoreactive with antibodies to Borrelia burgdorferi but are not substantially immunoreactive with antibodies to Treponema pallidum, the syphilis causing agent. DNA sequences of the antigens, clones and vectors containing the DNA sequences are also disclosed. Polypeptides derived therefrom can be used as reagents for the detection of antibody to Borrelia burgdorferi in the body fluids from individuals with Lyme disease.

Abstract: There is disclosed structured lipid containing either a gamma-linolenic acid or a dihomogamma-linolenic acid residue, together with an n-3 fatty acid residue and a medium chain fatty acid residue on the same glycerol backbone. This structured lipid is particularly well adapted to the treatment of disease or stress states. The gamma-linolenic or dihomogamma-linolenic acid residues modify the prostanoid synthesis pathway, reducing the level of series "2" prostanoids and elevating the levels of series "1" and "3" prostanoids. The n-3 fatty acid residue enhances the level of series "1" prostanoids as well as increases the production of series "3" prostanoids. The medium chain fatty acid residues enhances the absorption of the structured lipid. There is also disclosed enteral and parenteral diets as well as nutritional supplements containing the structured lipids of the invention.

Abstract: A connecting system is provided with a connector adapted to be mounted to the end of a conduit for removably engaging a blunt cannula to establish fluid communication between the conduit and cannula. The connector has a housing which defines a passage for communicating with the conduit and which defines an opening to the passage. The housing also defines a generally frustoconical seating surface which decreases in diameter in the direction toward the opening. A generally fluid-impervious, resilient seal is retained within the housing passage against the seating surface. The seal defines a slit which can accommodate penetration by the blunt cannula and which can reseal upon withdrawal of the blunt cannula.
Abstract: Cyanide-free reagents for the determination of hemoglobin and leukocytes present in a blood sample contain an aqueous solution of at least one quaternary ammonium salt, preferably selected from the group of alkyltrimethylammonium salts, alkyldimethylbenzylammonium salts or alkylpyridium salts consisting of tetradecyltrimethyl ammonium bromide (TTAB), dodecyltrimethyl ammonium chloride, cetyltrimethyl ammonium bromide, hexadecyltrimethyl ammonium bromide and benzalkonium chlorides, and hydroxylamine salts, especially hydrochloride, sulfate and phosphates and other acid salts. The method involves mixing the reagent with a diluent- diluted blood sample, presenting it to an absorbance spectrophotometer and measuring the resulting optical density as an indicator of hemoglobin concentration. This cyanide-free reagent could be used solely for hemoglobin determinations, or , it can also be used in leukocyte counting and sizing using hematology instrumentation.
Abstract: The present invention discloses a process for the preparation of a hydroxymethylthiazole compound having formula 3: The process of the invention comprises reacting a halomethyl thiazole having the formula: ##STR1## with water, at an elevated temperature. Optionally, the reaction can be carried out in the presence of a base, such as sodium carbonate, which can react with any acid formed. In the process of the invention, X is a halogen atom; and R.sup.6 is selected from the group consisting of hydrogen, and halogen atoms. The invention also contemplates the preparation of acid addition salts of the hydroxymethylthiazole, compound 3.
Abstract: A liquid heater assembly including a heater body having therein a coiled tube for passing liquids, a pair of heating elements, a thermistor, a thermostat, and a backup thermostat. Liquid enters the coiled liquid tube at an inlet end and exits the coiled liquid tube at an outlet end. The coiled liquid tube is positioned within the heater body between the pair of heating elements. The outlet end extends below a planar surface of the heater body. The thermistor detects the temperature changes of the heater body. The resistance of the thermistor is used to regulate the supply of power to the heating elements. The thermostat and the backup thermostat are connected in series between the power source and the heating elements to provide a safety shutoff when the heater body reaches a predetermined overheat temperature. The heater body is maintained at a predetermined temperature by regulating the electrical current to the heating elements.

Abstract: The present invention provides a method for quantitatively detecting the amount of a target nucleic acid sequence which may be present in a test sample. A test sample which may contain a target nucleic acid sequence comprising target sequences X and Y is contacted with two primer sets, the first set being specific for target X and the second set being specific for target Y. The test sample also is contacted at the same time with an internal standard sequence IS, which is substantially derived from a combination of the first and second target sequences, and its corresponding oligonucleotide primers. Haptens are associated with the oligonucleotide primer sets in such a way that amplified target sequence products X and Y are detected by capture on a solid phase to which anti-hapten capture reagents are attached. A signal ratio of (X+Y)/S is determined to quantitate the amount of the target nucleic acid sequence contained in the sample.
