  • Publication number: 20130017198
    Abstract: A novel mechanism by which after-depolarization occurs in cardiac myocytes has been discovered, involving calcium influx through the arachidonate-regulated calcium channel (ARCC) and the store-operated calcium channel (SOCC). Because after-depolarization of the myocyte is a major cause of cardiac arrhythmia, this discovery provides new approaches for treating and preventing heart disease. By down-regulating the activity of the ARCC or the SOCC, after-depolarization can be decreased and cardiac arrhythmia can be prevented, reduced, or eliminated. This can be accomplished using pharmaceuticals containing inhibitors of the ARCC or the SOCC, or by genetically modifying cells to reduce ARCC or SOCC activity. In addition, assays are disclosed using the ARCC or SOCC to discover potential anti-arrhythmic agents. Cellular and animal models of arrhythmia are disclosed in which the activity of the ARCC or SOCC is increased to promote after-depolarization and induce arrhythmia.

The use comprises assaying PAF-AH activity in a sample from the subject and comparing the measured activity to a reference value, wherein a lower level of measured PAF-AH activity relative to said reference level of PAF-AH activity indicates a presence of or susceptibility to severe or fatal anaphylaxis in the subject. A method for treating or preventing severe or fatal anaphylaxis in a subject is also provided. The method comprises increasing serum platelet activating factor acetylhydrolase (PAF-AH) concentration in the subject by administering to the subject, PAF-AH and/or a PAF receptor antagonist.

    Abstract: The invention provides an improved design for the construction of extensible nucleic acid-based, ligand-controlled regulatory systems, and the nucleic acid regulatory systems resulting therefrom. The invention contemplates improving the design of the switches (ligand-controlled regulatory systems) through the design of an information transmission domain (ITD). The improved ITD eliminates free-floating ends of the switching and the competing strands, and localizes competitive hybridization events to a contiguous strand of competing and switching strands in a strand-displacement mechanism-based switch, thereby improving the kinetics of strand-displacement. The improved regulatory systems have many uses in various biological systems, including gene expression control or ligand-concentration sensing.

  • Publication number: 20120149046
    Abstract: This invention relates to bioluminescent methods for detecting specific target bacteria, such as E. coli, coliforms, Enterococcus spp, Listeria spp and S. aureus in samples. The sample to be tested is incubated in a non-selective growth medium for up to 8 hours to produce a sample culture and which is then mixed with detection reagents. The detection reagents include a lysis reagent which disrupts bacterial cells in the sample, a pro-luciferin molecule which is specifically converted into luciferin by said target bacteria; and luminescence reagents which produce a luminescent signal in the presence of luciferin. The mixture of sample culture and detection reagents is then incubated and the luminescent signal from the reaction mixture measured.

  • Patent number: 8198038
    Abstract: The present invention relates to a plasma biomarker for diagnosing hepatocellular carcinoma (HCC), in particular to the discovery of a protein in plasma using 2-D fluorescence differential gel electrophoresis (2-D DIGE), immunoprecipitation and Nano-liquid chromatography mass spectrometry (Nano-LC-MS/MS) system that was unknown on the basis of conventional techniques. By demonstrating the presence of liver carboxylesterase 1 (hCE1) in human plasma and confirming that its secretion level is higher in patients with HCC than in healthy volunteers, this invention may be used as a screening method to diagnose HCC at an early stage.

  • Publication number: 20120141630
    Abstract: Lipolytic enzymes which improve the properties of dough or baked products generally have a high activity towards lipids which are capable of forming a hexagonal phase, and a screening method was developed on this basis. The improved properties may include a larger loaf volume, an improved shape factor, an improved crumb structure, reduced dough stickiness, improved dough stability and/or improved tolerance towards extended proofing. The advantageous lipid-degrading enzymes have higher activity towards MGDG and/or unsaturated phosphatidyl ethanolamines (APE, PE) than towards DGDG, PC, PS, PI, PG, saturated phosphatidyl ethanolamines, ALPE and/or triglicerides.
