  • Publication number: 20170102349
    Abstract: Disclosed are compositions and methods for the electrochemical detection of enzymes, such as enzymes that are indicative of disease, disorders, or pathogens, such as viruses, bacteria, and fungi, or other disorders. These methods can be used in point-of-care diagnostic assays for the detection of disease, disorder, or pathogen (e.g., to identify the strain of pathogen infecting a patient in a healthcare setting). The electrochemical methods described herein can also be used to assess the susceptibility of a pathogen to an antipathogen drug. Also provided are probes suitable for use in conjunction with the methods described herein.

  • Patent number: 9091772
    Abstract: A method, apparatus, and computer program products for controlling gain in a scintillation detector. Calibration count rates, each representing an integral count rate above a different threshold, are obtained from a photomultiplier tube. Photomultiplier tube gain is adjusted if a result from evaluating a relationship of calibration count rates varies from an expected result based on integral count rate versus threshold for a reference peak in the energy spectrum of the radiation source. An additional, different relationship may also be evaluated and an additional gain adjustment performed when a result indicates that the calibration count rates are not from the reference peak. A same radiation source may be used for collecting test counts and calibration counts.
