  2. 21. Aspects of aetiology, pathoanatomy and diagnostic methods in chronic mid-portion achillodynia

    Author : Tomas Movin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Achilles tendon; achillodynia; pathology; MR-imaging; ultrasonography; gadolinium; contrast enhancement; glycosaminoglycan; aetiology; core biopsy.;

    Abstract : The objectives of this thesis are to study aetiology and pathoanatomy, and to evaluate diagnostic methods in patients with long-standing pain and tenderness localised to the mid portion of the Achilles tendon. Treatment had failed to relieve symptoms prior to referral to our clinic, where some of these patients underwent surgical treatment. READ MORE

  4. 22. Studies on production and function of pulmonary nitric oxide

    Author : Christofer Adding; Karolinska Institutet; Karolinska Institutet; []
    Keywords : adrenaline; adrenoceptors; beta-adrenoceptors; calcium; carbon dioxide; catecholamines; chemiluminescence; exhaled; gadolinium chloride; high frequency oscillatory ventilation; nitric oxide; pulmonary; pulmonary circulation; stretch; sympathoadrenal; veratrine;

    Abstract : Nitric oxide is involved in pulmonary vascular and bronchial regulation and appears to be of paramount importance in the adaptation of the pulmonary circulation at birth. Nitric oxide is present in exhaled gas. READ MORE

  5. 23. Mechanisms of adaptation in a mechanoreceptor : a study of mechanical and ionic factors in the crayfish stretch receptors

    Author : Nuhan Purali; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Crayfish; stretch receptor; adaptation; visco-elastic properties; mechanosensitive channels; potassium channels; sodium channels; gadolinium; tetraethylammonium chloride; 4-amino pyridine; scorpion venom Leiurus quinquestrialus;

    Abstract : The stretch receptor organ of the crayfish, an analog to the human muscle spindle, is a unique preparation for the study of mechanotransduction. The organ consists of a rapidly and a slowly adapting receptor each composed of a receptor muscle fibre into which inserts the dendrites of a multipolar sensory neuron. READ MORE

  6. 24. Failure mechanisms in APS and SPS thermal barrier coatings during cyclic oxidation and hot corrosion

    Author : Krisha Praveen Jonnalagadda; Ru Lin Peng; Xin-Hai Li; Robert Eriksson; Shrikant Joshi; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Thermal Barrier Coatings (TBCs) are advanced material systems that are being used in the hot sections of gas turbines such as combustor, turbine blades, and vanes. The top ceramic coating in TBCs provides insulation against the hot gases and the intermediate metallic bond coat provides oxidation and corrosion resistance to the underlying turbine components.
