Abstract:
A latching piercing pin (20) usable to retain the pin and an associated fluid vial (37) in latching relation. Latching members (32) provided on the pin engage a peripheral lip provided on the end cap of the vial to maintain the latching relation between the pin and the vial. The pin is usable with vials and end caps of varying sizes, although larger end caps may require the mounting of a locking ring on the end cap of the vial to receive and engage the latching piercing pin.
Abstract:
Compounds of structure (1) where Ar is optionally substituted carbocyclic aryl, 5- or 6-membered heterocyclic aryl, 10-membered bicyclic heterocyclic aryl containing one or two nitrogen atoms, 9- or 10-membered heterocyclic containing one or two nitrogen atoms and optionally containing a further nitrogen or oxygen atom and one oxo or thioxo substituent, benzo(b)furyl, benzo(b)thienyl, A1 is propynylene, methylene, or a valence bond, X is O, S, SO2,or NR2, Y is selected from alkyl, haloalkyl, alkoxy, halogen, and hydrogen, A2 is selected from (a), (b) and methylene, where Z is OR5 or NHR5 where R5 is hydrogen or alkyl, R1 is hydrogen, alkyl, or OR5, and m and n are integers having a value of 1 or 2 are potent inhibitors of lipoxygenase enzymes and thus inhibit the biosynthesis of leukotrienes. These compounds are useful in the treatment or amelioration of allergic and inflammatory disease states.
Abstract:
A system for detecting the position of an object within a body of biological tissue includes a resonant circuit attached to the object and a probe (10) including a receiver/transmitter that operates at the resonant frequency of the object. The resonant circuit rings in response to pulses transmitted from the probe (10) thereby activating receiver circuits which control a visual display (24) indicating the direction the probe should be moved to center it over the object. When the object is centered a second visual display (22) provides confirmation.
Abstract:
Assay methods and reagents for determining the presence or amount of immunophilin ligands and immunophilins thereof employing a recombinant fusion protein comprising (i) an immunosuppressant binding protein and (ii) a heterologous protein are disclosed. The recombinant fusion protein can also be employed for the evaluation of immunosuppressive activities of immunosuppressive agents in order to determine the efficacy of an immunosuppressive agent during the course of therapeutic treatment of a patient therewith. Preferably, the recombinant fusion protein comprises a macrolide immunosuppressive agent and CTP:CMP-3-deoxy-D-manno-octulosonate cytidylyl transferase. When employed in a binding assay format, the recombinant fusion protein provides higher reactivity for the immunophilin ligand under determination than does the native immunosuppressant binding protein. In particular, an immunosuppressant assay reagent comprising FK-506 binding protein (FKBP) and CKS immobilized to a solid support material provides a higher signal-to-noise ratio when employed in a competitive heterogeneous assay format than when native FKBP immobilized to a solid support material is employed in such assay format.
Abstract:
This invention discloses that certain fragments of a pulmonary surfactant protein exhibit unexpected surface activity. These protein fragments are useful in preparing formulations for the treatment of respiratory distress syndrome.
Abstract:
The present invention relates to immunoassay methods for detecting and measuring the amount of an analyte in a sample by means of generic anti-hapten antibodies. Also disclosed are multi-analyte immunoassay methods. Reagents, devices, and kits using the anti-hapten antibodies are also disclosed. The present invention also relates to dyed erythrocytes, preferably fixed, which are coated with antibodies. Also disclosed is the use of these dyed erythrocytes in agglutination assays to detect and measure the presence of an analyte in a sample. The analyte can be a hapten, an antigen, or an antibody. Also included are agglutination assays, compositions and kits using these dyed and coated erythrocytes.
Abstract:
The invention relates to multiplex ligase chain reaction (LCR). Two or more putative target sequences are selected. For each one, a set of four probes is used simultaneously to amplify the putative sequence if it is present in the sample. Preferably, all the amplicons are labeled with a common label/hapten and, for each different target, with a unique label/hapten. The invention also relates to an immunochromatographic strip device and method employing a diagonal array of capture spots.
Abstract:
A competitive immunoassay to measure lipoprotein a [Lp(a)] levels semiquantitatively and identify individuals with elevated plasma Lp(a) protein levels (greater than 7 mg/dl) who have an increased risk for coronary artery disease is performed using a teststrip. The teststrip includes an application pad (10) attached to the top side of a porous strip (20) containing an immobilized antibody. The antibody is immobilized in a measurement region (30) which can involve a plurality of capture sites (35). Typically, the upper surface of the application pad (10) and porous strip (20) are laminated with an impermeable membrane (40) and the assembled device is attached to the top of a support material (50). In addition, the device may optionally include an end of assay indicator (60) which produces a detectable signal upon contact with the test sample or an assay reagent. The assay provides a quick, reliable, easy to use and inexpensive method to measure plasma Lp(a) level with serum, plasma or whole blood.
Abstract:
A liquid nutritional product for trauma and surgery patients has a caloric density of about 1.2 to 1.5 Kcal/mL and a calorie to nitrogen ratio of about 112:1 to 145:1. A portion of the protein system comprises partially digested protein, and supplemental L-arginine provides about 1-3 % of the total calories in the product. The lipid system has a ratio of linoleic acid to alpha linoleic acid in the range of about 3.5:1 to about 5.5:1.
