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

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

    Sammanfattning : 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. LÄS MER

  4. 18. Regulation of the myogenic response and stretch-induced calcium signaling in the vascular wall: Novel insights into the role of microRNAs and protein tyrosine kinase 2

    Författare :Anirban Bhattachariya; Kärlfysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; portal vein; resistance artery; myogenic tone; PYK2; calcium; microRNA;

    Sammanfattning : Intraluminal pressure has a significant impact on vascular adaptability, phenotype and regulation of blood flow and pressure. On one hand, increased pressure/stretch for a prolonged time can cause structural changes in vessel wall; on the other hand, lack of pressure/stretch can promote a phenotype shift. LÄS MER

  5. 19. Theoretical and Experimental Investigations of Nonlinear Flame Instability

    Författare :Li-Zheng Ma; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nonlinear hydrodynamic instability; flame propagation and stretch effects; shock induced flame instability; tulip flame formation; interface tracking; the Schlieren technique; level set approach;

    Sammanfattning : Flame instability is both important and difficult to understand. Mechanisms of instability are complex, because instability often involves an interaction between several different physical phenomena, such as an unsteady chemical reaction, unsteady flame propagation generating an unsteady flow, acoustic waves or shock waves.

  7. 20. Studies on production and function of pulmonary nitric oxide

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

    Sammanfattning : 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. LÄS MER
