  1. 1. Chronic atrial fibrillation in man. Activation, organisation and characterisation

    Author : Magnus Holm; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ECG spectral analysis; Preferential conduction; Organisation; Conduction velocity; Refractoriness; Mechanisms; Activation pattern; Chronic; Fibrillation; Human; Atrium; Open-heart surgery; Cardiovascular system; Kardiovaskulära systemet;

    Abstract : Chronic atrial fibrillation (CAF), with a prevalence progressively increasing with age, is one of the most common cardiac arrhythmias in man and associated with increased morbidity and mortality. Previous studies have shown that, in animals as well as in man, experimental atrial fibrillation is based on different types and dimensions of intra-atrial electrical re-entry. READ MORE

  2. 2. On the Biosynthesis and Processing of Cathepsin G, Leukocyte Elastase, and Azurocidin ­ neutrophil granule members of a hematopoietic serine protease superfamily

    Author : Anders Lindmark; Avdelningen för hematologi och transfusionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular fluids; Haematology; sorting; Activation; propeptide; Hematologi; extracellulära vätskor;

    Abstract : The serine proteases cathepsin G, leukocyte elastase, proteinase 3, and the inactive protease homologue azurocidin, stored in the azurophil granules of neutrophils, belong to a hematopoietic serine protease superfamily with members in mature effector cells of bone marrow origin. Promonocytic U-937 cells were used for studying the biosynthesis of cathepsin G and leukocyte elastase by biosynthetic radiolabelling. READ MORE

  3. 3. Pattern recognition and iNKT cell regulation of B cell activation

    Author : Chenfei He; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The immune system protects individuals against infections but can cause disease if the response is unbalanced. Immune responses include both innate and adaptive response, and these systems are connected. As the first line of defense, innate immune responses are immediately induced upon infection. READ MORE

  4. 4. Pattern-recognition receptors in airway inflammation

    Author : Anna-Karin Ekman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Airway inflammation is a defining feature of allergic rhinitis and asthma. Bacterial and viral infections are known to cause exacerbations of both diseases, but knowledge about the mechanisms involved is limited. READ MORE

  5. 5. Computer Simulation of the Neural Control of Locomotion in the Cat

    Author : Nalin Harischandra; Örjan Ekeberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Locomotion; Computer simulation; Central pattern generator; Muscle activation; Linear transfer functions; Sensory feedback; Neural control; Computer science; Datavetenskap;

    Abstract : Locomotion is one of the most important behaviours and requires interaction between sensors at various levels of the nervous system and the limb muscles of an animal. The basic neural rhythm for locomotion in mammals has been shown to arise from local neural networks residing in the spinal cord and these networks are known as central pattern generators (CPGs).
