| 20130078726 | Method of Recovering Heavy Metal and Reagent for Recovery of Heavy Metal for Use in the Same - The present invention provides a method of recovering a heavy metal by which the variation in heavy metal recovery rate among samples can be suppressed. A mixture of a sample and a chelating agent capable of chelating with a heavy metal is prepared. A complex between a heavy metal being in the sample and the chelating agent is formed in the presence of a masking agent for a thiol group in the mixture. The heavy metal in the sample is recovered by recovering the complex. By this method, a heavy metal can be recovered with suppressing the variation in the recovery rate among samples. The chelating agent preferably is 1,5-diphenyl-3-thiocarbazone (dithizone). As the masking agent, N-ethylmaleimide, iodoacetamide, iodoacetic acid, or the like can be used. | 03-28-2013 |
| 20100151579 | FLUORESCENT SENSOR FOR MERCURY - The present invention provides a sensor for detecting mercury, comprising: a first polynucleotide, comprising a first region, and a second region, a second polynucleotide, a third polynucleotide, a fluorophore, and a quencher, wherein the third polynucleotide is optionally linked to the second region; the fluorophore is linked to the first polynucleotide and the quencher is linked to the second polynucleotide, or the fluorophore is linked to the second polynucleotide and the quencher is linked to the first polynucleotide; the first region and the second region hybridize to the second polynucleotide; and the second region binds to the third polynucleotide in the presence of Hg | 06-17-2010 |
| 20120190119 | METHOD AND SYSTEM FOR MODULATING SUBSTANCES IN THE FORMATION VITAMINS - A method for establishing a treatment for promoting the formation of Vitamins in an individual. The measured or assessed level of substances in the body are compared in order to determine the treatment to provide to an individual. | 07-26-2012 |
| 20110014712 | METHOD, DEVICE AND APPARATUS FOR MEASURING THE CONCENTRATION OF CREATININE, AND METHOD, DEVICE AND APPARATUS FOR MEASURING THE AMOUNT OF SALT USING THE SAME - A method for measuring a concentration of creatinine includes the steps of: (A) mixing a sample containing creatinine with a creatinine quantitative reagent containing a metal complex of at least one of hexacyanoferrate and hexacyanoruthenate in the absence of picric acid and any enzyme responsive to creatinine, to cause the creatinine to reduce the metal complex; (B) electrochemically or optically measuring the amount of the metal complex reduced in the step (A); and (C) determining the concentration of the creatinine contained in the sample from the amount of the reduced metal complex measured in the step (B). | 01-20-2011 |
| 20120058564 | TEST KIT AND METHOD FOR MEASUREMENT OF METALS IN BIOLOGICAL FLUIDS - A test kit and a biomedical process is provided to estimate metals particularly non-transferrin bound iron levels (NTBI) in circulating body fluids particularly, serum. NTBI appears in serum when there is excess iron in the body. The method comprises of employing a signal generating moiety capable of complexing with iron that is a peptide like molecule having an iron binding site and also an optical signal generating functional group. The molecule is of microbial origin. The measurement is based on the alteration of optical characteristics of the probe molecule upon attachment of iron to its binding site on the molecule. Hence it generates a signal proportionate to the amount of iron available for binding and provides a direct estimate of free or unbound iron in the sample. According to this instant invention a rapid estimation method of NTBI in body fluids can be undertaken in an inexpensive way without the need of specialized expertise. | 03-08-2012 |
| 20120258543 | BIOGENIC SUBSTANCE MEASURING METHOD - To provide a method configured to effectively control in a simplifier manner any adverse influences from perspiration excreted from a skin currently measured when a biogenic substance from tissue fluid extracted through fine pores is measured, the method includes steps of: forming a film having a water impermeability on the test subject's skin; forming fine pores in the skin coated with the film so as to penetrate through the film; extracting the tissue fluid from the test subject through the skin where the fine pores are formed; storing the constituent to be measured and inorganic ions of the extracted tissue fluid; obtaining an ion information relating to a quantity of the stored inorganic ions and a constituent information relating to a quantity of the stored constituent; and obtaining an analysis value relating to the quantity of the constituent based on the ion information and the constituent information. | 10-11-2012 |
