Abstract: Assay methods for analyzing whole blood to detect histamine H4 receptor-mediated effects, such as eosinophil shape change, cytoskeletal change, adhesion molecule up-regulation, or calcium flux are described. Such methods are useful in clinical and diagnostic applications.

Abstract: An automated system that conducts, monitors, and validates a cell-line-based biological experiment including one or more treatment compounds or other external stimuli. In one preferred embodiment, the system comprises two principal subsystems, and optionally accessory subsystems. A first principal subsystem is an automated laboratory experiment manager for designing the biological experiment, for constructing an assay plate used to conduct the biological experiment, and for managing one or more of the processes that constitute the biological experiment. A second principal subsystem is an automated data analysis manager for analyzing images, for instance produced by the image production system, to detect image data including biological markers and objects, for analyzing the resulting image data to produce biological data, and for analyzing the biological data to produce biological phenotypes and treatment compound signatures.

Abstract: The invention disclosed a trace following powered amplifier mainly used in solving the problem of circuit overheating caused by long test time, especially to an amplifier applicable to a low frequency and low distortion test apparatus such as a capacitor ripple current tester. The amplifier of present invention can make the most efficient use of electrical energy by incorporating a low frequency voltage peak value of an amplifier signal plus an estimated tolerance.

Abstract: Methods are disclosed for identifying histamine receptor modulators that affect mast cell or basophil chemotaxis, and the use of such histamine H4 receptor modulators for the prevention, treatment, induction, or other desired modulation of asthma and/or allergic responses, or diseases and/or conditions that are modulated, affected or caused by asthma or allergic responses. Also disclosed is the use of histamine H4 receptor modulators for the prevention, treatment, induction, or other desired modulation of mast cell or basophil chemotactic responses, such as migration to a particular site, or diseases and/or conditions that are modulated, affected or caused by mast cell or basophil chemotaxis.

Abstract: A coating apparatus and method for applying a coating to a workpiece, comprising:a vessel to contain molten metal;an induction coil disposed about said vessel; and,temperature regulation means;wherein, in use, said induction coil induces a magnetic field within said vessel such that a meniscus of molten metal is formed above said vessel, through which said workpiece is passed for coating, whilst said temperature regulation means regulates temperature of said molten metal and/or controls the meniscus height of said meniscus.

Abstract: Analysis of the culture media of p40-transfected COS cells indicated the presence of 40 kDa monomers and 80 kDa disulfide-linked homodimers. Examination of partially purified p40 recombinant proteins demonstrated that only the homodimer but not the monomer binds to the IL-12 receptor. Partially purified 80 kDa homodimer inhibited [.sup.125 I]IL-12 binding to PHA-activated human lymphoblasts with an IC.sub.50 of 80 ng/ml, which is similar to the IC.sub.50 value (20 ng/ml) for the human IL-12 heterodimer. Although neither the 40 kDa monomer nor the 80 kDa dimer could stimulate human PHA-blast proliferation, the 80 kDa dimer inhibited IL-12-induced proliferation in a dose-dependent manner with an IC.sub.50 of 1 .mu.g/ml. The IL-12 p40 subunit contains the essential epitopes for receptor binding, but they are only active when p40 is covalently associated with a second protein such as p35 or p40. When p40 is associated with the p35 subunit, the heterodimer acts as an agonist mediating biologic activity.
