    摘要： The present invention is directed to a multi-compartment medical device for segregated storage and on demand mixing of at least two components and expression of a resulting mixture from the device having a tubular barrel with an opening and a gasket sealing the rear end through which a plunger is axially slidable within the tubular barrel. At least one bypass is provided in the barrel in order to enable fluid movement of the components between front and rear compartments and rear compartments. The present invention is also directed to methods for the use of such devices.

    摘要： In one aspect, the present invention features a process for making a tablet including a pharmaceutically active agent wherein the tablet has both an immediate release region and a modified release region. The method includes the steps of: (a) forming a tablet shape including a powder blend containing a pharmaceutically active agent and a thermally-sensitive material; and (b) applying energy in different amounts to different regions of the tablet shape to form the tablet in a manner such that: (i) a first region of the tablet shape is exposed to said energy for a sufficient period of time to melt the thermally-sensitive material within the first region to form said modified release region of said tablet; and (ii) a second region of said tablet shape is not so exposed to the energy such that said second region forms the immediate release region of said tablet.

    摘要： In the present invention, a reagent capable of immunospecific reaction with the analyte of interest is conjugated to a photocatalytic microparticle. After the immunospecific binding has occurred, the assay amplification is performed by exposing photocatalytic particles to actinic UV light in presence of an oxidizable compound. Photocatalytic particles are catalyzing multiple occurrences of oxidation of oxidizable compound under UV light irradiation resulting in detectable changes such as color change. This provides for amplification of each single act of immunospecific binding and is followed by colormetric detection. Thus a high sensitivity quantitative or qualitative immunoassay can be realized.
