摘要:
A self-sustaining solenoid which is adapted so that when applying an operating current to a coil, a moving iron core disposed in the coil is attracted into contact with a fixed receiver. A magnetic yoke is provided to extend between the fixed receiver and the end portion of the moving iron core projecting out of the coil, and a permanent magnet is disposed on the magnetic yoke at least at one end in the direction of movement of the moving iron core. When the moving iron core is held in contact with the fixed receiver, magnetic fluxes emanating from the permanent magnet mostly pass through the moving iron core, the fixed receiver and the magnetic yoke, and even if the operating current is cut off, the moving iron core is retained in contact with the fixed receiver. A magnetic gap is provided through which the magnetic fluxes of the permanent magnet mostly pass when the moving iron core is out of contact with the fixed receiver, and magnetic flux resulting from the application of the operating current pass through the magnetic gap.

摘要:
Methods for diagnosing rheumatoid arthritis (RA) are disclosed, using measurement of the CCL8 protein level in a test sample from a subject. Testing for CCL8 as an indicator of RA can be combined with testing for other indicators of RA, including clinical assessments, imaging or other RA markers such as Rheumatoid factor (RF). CCL8 testing can be used for discriminating RA from other diseases or conditions, evaluating the severity of RA. Related diagnostic reagents, kits, pharmaceutical compositions, and methods for identifying a candidate substance as a therapeutic agent for treating rheumatoid arthritis are also described.
摘要:
In immunoassays such as homocysteine immunoassays, it is known that the measured values can be dispersed due to the influence of inhibiting substances present in a biological sample on the immunoreaction. The present invention provides among other things a method whereby the influence of the immunoreaction inhibiting substances is easily and efficiently suppressed or eliminated, and also provides a kit used for such a method. The influence of the immunoreaction inhibiting substances is suppressed or eliminated when the analyte (e.g., homocysteine) contained in the biological sample is reacted with the antibody in the presence of extrinsic polyanion.
摘要:
A first rocker arm is used to induce valve lift while a second one used to move the valve back to closed position. The rocker arms are arranged to engage the valve top or retainer surfaces at locations offset from the axis of the valve and to induce the valve to rotate during the lift and closing operations. Springs, hydraulic lifters or double adjust screw type arrangements are used to control clearances.
