Finally, IWR-1-endo ic95 the Multithreaded Application Real-Time executor (MARTe) framework is used for building applications particularly optimised for exploring multi-core architectures. In the past year, four new systems based on this philosophy have been installed and are now part of JET’s routine operation. The focus of the present work is on the configuration aspects that enable these new systems’ real-time capability. Details are given about the common real-time configuration of these systems, followed by a brief description of each system together with results regarding their real-time performance. A cycle time jitter analysis of a user-space MARTe based application
synchronizing over a network is also presented. The goal is to compare its deterministic performance while running on a vanilla and on a Messaging Real time Grid (MRG) Linux kernel.”
“Background: this website Allergic disorders, such as seasonal rhinitis and asthma, are increasing causes of morbidity worldwide and often result from exposure to airborne pollen. Pollen allergy has a remarkable clinical impact all over Europe. In fact, epidemiological longitudinal studies confirm that pollen species usually considered with low allergenic potential became more recently responsible for intense allergic reactions. In this study, we aimed to characterize major pollen proteolytic activity and evaluate
its contribution to the immunologic and inflammatory response to airborne allergens.\n\nMethods: Proteolytic activity in four pollen diffusates with distinct allergenicity, Olea europaea,
Dactylis glomerata, Cupressus sempervirens and Pinus sylvestris, was evaluated through several enzymatic assays. The action of pollen proteases on the paracellular integrity of Calu-3, grown at the air-liquid interphase, was evaluated through a transepithelial permeability assay. Immunoblot and immunofluorescence experiments were performed to analyse the disruption of intercellular complexes. Degradation of bioactive peptides by pollen crude extracts JIB 04 was assessed by mass spectrometry.\n\nResults: All pollen diffusates were shown to have high molecular weight proteases with serine and/or aminopeptidase activity. These proteases increased Calu-3 transepithelial permeability through disruption of transmembrane adhesion proteins: occludin, claudin-1 and E-cadherin. Moreover, they were able to degrade airway bioactive peptides and were not blocked by endogenous protease inhibitors.\n\nConclusion: Pollen grains with distinct allergenic abilities release proteases that might be involved in the sensitization to a range of airborne allergens by facilitating allergen delivery across the epithelium and also contribute directly to the inflammation characteristic of allergic diseases.
