Background: Celery root is known to cause severe allergic reactions in patients sensitized to mugwort pollen.
Objective: We studied clinically well-characterized patients with celery allergy by IgE testing with a comprehensive panel of celery allergens to disentangle the molecular basis of what is known as the celery-mugwort syndrome.
Methods: Patients with suspected food allergy to celery underwent a standardized interview.
Human genetic studies based on the Marburg I polymorphism in the factor VII activating protease (FSAP) encoding gene, analysis of FSAP activity in plasma and biochemical characterization of FSAP substrates indicate a possible causal link between FSAP activity and venous thrombosis. We hypothesized that a direct standardized assay to measure FSAP activity in plasma could provide convincing arguments for or against such a potential link. Using Ac-Pro-DTyr-Lys-Arg-AMC as a highly specific and sensitive substrate, histones as a trigger to activate pro-FSAP and plasma-purified active FSAP as a calibrator, we have developed a fluorogenic kinetic assay that reveals the FSAP generating potential in human plasma in real time.

Methods: We describe the novel reporter fluorescence real-time polymerase chain reaction (PCR) probe system for detection of species.
Background And Objectives: Red blood cell concentrates (RBCC) are susceptible to bacterial contamination despite cold storage. A reliable evaluation of strategies to minimize the risk of RBCC-associated bacterial transmission requires the use of suitable reference bacteria. Already existing Transfusion-Relevant Bacteria Reference Strains (TRBRS) for platelet concentrates fail to grow in RBCC.
