One-step rapid assay for the detection of inhibitors of enzymes
A device and method for the rapid on-site detection of inhibitors of enzymes, such as acetylcholinesterase, is described wherein the device contains all reagents added to a sample pad containing dried releasable enzyme creating a reaction mixture wherein inhibitor deactivates the enzyme, while said reaction mixture travels via a longitudinal membrane to a distal porous pad containing a substrate for the enzyme. The reaction of the enzyme and the substrate results in a product that can generate a measurable signal such as color, fluorescence or luminescence to serve as a reporter. Signal that is generated at this reaction zone is inversely proportional to inhibitor concentration in the test sample. A device containing two such strips, one for a test sample, the other for a negative control fluid as an onboard comparator is described. A purpose-built reader or an illuminating device, such as, containing an incandescent light source, a diode, a UV light source or any other illumination source that is suitable for the reporter or mere visualization is used to determine the level of reporter.
METHOD FOR DIAGNOSING AND TREATING BLOOD CANCER
The present invention provides: a method for identifying a blood cancer patient who may benefit from a monotherapy using a drug comprising a DNA methyl transferase inhibitor and a combination therapy using the aforesaid drug together with another epigenetic controller; a pharmaceutical composition to be used in treating a patient who has been identified or selected by the method; and a kit for identifying such a patient. More particularly, the aforesaid method comprises a step for measuring the expression amount of DUSP5 in a sample obtained from a blood cancer patient. When the expression amount measured in this step is lower than a reference expression amount of DUSP5, then the patient is identified or selected as a blood cancer patient who may benefit from a treatment using the drug comprising a DNA methyl transferase inhibitor.

Methods and Reagents Useful for Verification of the Integrity of a Urine Sample and the Detection of Counterfeit Urine
The problem of detecting whether a urine sample is true human urine or a counterfeit urine product is solved by the use of reagent systems that detect two markers normally present in human urine. The markers acid phosphatase and alkaline phosphatase catalyze the substrates thymolphthalein monophosphate and p-nitrophenol phosphate, respectively. These substrates are formulated as spot tests on a dip stick or as reagents for use in automated chemical analyzers. The presence of the markers can be qualitatively detected by color-changes in the sample, formed by the pH-specific chromogens that result from catalysis of the substrates with the markers. The control reagent can further indicate whether a counterfeit urine product contains one or both of the chromogens.
