Abstract: A plating medium for the presumptive identification of Bacillus cereus, Bacillus thuringiensis and/or Bacillus anthrasis that includes a nutrient base to facilitate growth of Bacillus cereus, Bacillus thuringiensis and Bacillus anthrasis, a chromogenic substrate that changes color responsive to the presence of PC-PLC enzymes, and an ingredient that promotes the expression of the PC-PLC enzyme. In a preferred embodiment, the medium includes a second chromogenic substrate that changes color responsive to the presence of PI-PLC enzymes and an ingredient that promotes the expression of the PI-PLC enzyme.
Abstract: An assay is disclosed for measuring activity of enzymes, such as kinases, phosphatases, and proteases. Measurements of enzymatic activity are accomplished in a homogenous assay format utilizing a fluorescence quenching technique employing paramagnetic metal ions.
Abstract: A lanthanide is combined with a medium to be tested for endospores. The dipicolinic acid released from the endospores binds the lanthanides, which have distinctive emission (i.e., luminescence) spectra, and are detected using photoluminescence. The concentration of spores is determined by preparing a calibration curve generated from photoluminescence spectra of lanthanide complex mixed with spores of a known concentration. A lanthanide complex is used as the analysis reagent, and is comprised of lanthanide ions bound to multidentate ligands that increase the dipicolinic acid binding constant through a cooperative binding effect with respect to lanthanide chloride. The resulting combined effect of increasing the binding constant and eliminating coordinated water and multiple equilibria increase the sensitivity of the endospore assay by an estimated three to four orders of magnitude over prior art of endospore detection based on lanthanide luminescence.

Abstract: The application identifies fragments of alpha-synuclein in patients with Lewy Body Disease (LBD) and transgenic animal models thereof. These diseases are characterized by aggregations of alpha-synuclein. The fragments have a truncated C-terminus relative to full-length alpha-synuclein. Some fragments are characterized by a molecular weight of about 12 kDa as determined by SDS gel electrophoresis in tricine buffer and a truncation of at least ten contiguous amino acids from the C-terminus of natural alpha-synuclein. The site of cleavage preferably occurs after residue 117 and before residue 126 of natural alpha-synuclein. The identification of these novel fragments of alpha-synuclein has a number of application in for example, drug discovery, diagnostics, therapeutics, and transgenic animals.

Abstract: The peritoneal function of a peritoneal dialysis patient is examined to evaluate the condition of the patient. An examining method comprises a step of alternately repeating introduction/drainage of a predetermined quantity of a peritoneal dialyzing fluid of an osmotic pressure and introduction/drainage of a predetermined quantity of another peritoneal dialyzing fluid of an osmotic pressure different from the former one, a step of examining the drain to determine the quantity of peritoneal dialyzing fluid staying in the abdominal cavity of the patient and the concentration of a solute of interest, a step of conducting a peritoneal equilibrium test, and a step of conducting a blood test to grasp the change of the state of the blood caused by the introduction and drainage. The blood test step is executed only once.
Abstract: The present invention provides a method for the enzymatic measurement of protein tyrosine kinase inhibitors in biological samples.

Abstract: An elastomeric article that contains a chromogen that undergoes a detectable change in color in the presence of one or more microbes is provided. For example, in one embodiment, the chromogen is a solvatochromic dye (e.g., Reichardt's dye) that undergoes a color change in the presence of bacteria or other microbes. More specifically, such dyes may respond to differences in polarity between microbe components (e.g., cell membrane, cytoplasm, etc.) and the environment outside the cell. Alternatively, other mechanisms may be wholly or partially responsible for the interaction between the dye and the microbe, such as acid-base reactions, redox reactions, and so forth.

Abstract: Solvatochromic dyes are used herein to indicate the presence of bacteria by incorporating them into various substrates such as films, woven and nonwoven fabrics, paper towels, coform and airlaid materials and bonded carded webs. These dyes change color in response to a change in polarity of the environment. Since water is a polar solvent and most bacteria are made from non-polar substances, the presence of bacteria changes the polarity of the environment, triggering a change visible by the unaided eye. A lateral flow device incorporating solvatochromic dyes and a method of detecting bacteria are also included.
