  2. 2. Regulation of striated muscle contraction

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Physiology and Pharmacology

    Författare :Ying Dou; Karolinska Institutet.; Karolinska Institutet.; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background and Aims: Muscle contraction involves cross-bridge interaction between actin and myosin filaments, which is regulated by variations of intracellular [Ca2+] and influenced by several external control systems. To characterize the mechanism of contraction, we have studied the effects of pharmacological compounds influencing the actin-myosin interaction and/or Ca2+ activation systems. LÄS MER

  3. 3. Conctraction-mediating receptors in human peripheral vessels with special reference to veins and lymphatics

    Detta är en avhandling från Department of Surgery, Clinical Sciences Lund, Lund University

    Författare :Trygve Sjöberg; Lunds universitet.; Lund University.; [1989]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human; arteries; veins; lymphatis; contraction; in vitro; in vivo; adrenergic receptors; noradrenaline; cirazoline; phenylephrine; clonidine; calcium antagonists; nifedipine; diltiazem; prostaglandins; thromboxane A2; U-46619; BM-13.505; indomethacin;

    Sammanfattning : By means of a myograph, postjunctional alpha-adrenoceptors were characterized in human superficial epigastric arteries and veins obtained from health subjects. The rank order of potency of subtype selective agonists could not be used for receptor characterization in these vessels, whereas antagonists gave distinct results. LÄS MER

  4. 4. Biomechanical consequences of gait impairment at the ankle and foot Injury, malalignment, and co-contraction

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Ruoli Wang; KTH.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; muscle function; gait analysis; induced acceleration; foot kinematics; dynamic joint stiffness;

    Sammanfattning : The human foot contributes significantly to the function of the whole lower extremity during standing and locomotion. Nevertheless, the foot and ankle often suffer injuries and are affected by many musculoskeletal and neurological pathologies. LÄS MER

  5. 5. Novel functions of cardiovascular P2 receptors

    Detta är en avhandling från Anna-Karin Wihlborg, Department of Cardiology, Lund University

    Författare :Anna-Karin Wihlborg; Lunds universitet.; Lund University.; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; Kardiovaskulära systemet; mRNA; EDHF; UTP; UDP; ADP; ATP; P2 receptor; contraction; dilatation; endothelial cells; Heart; VSMC;

    Sammanfattning : Popular Abstract in Swedish Sammanfattning Nukleotider påverkar kärltensionen och hjärtats slagkraft. Då ett blodkärl skadas, då blod koagulerar eller vid minskad syretillförsel till hjärtat frisätts en mängd ämnen från kärlväggar och blodceller. Bland annat frisätts så kallade nukleotider (ATP, ADP, UTP och UDP). LÄS MER
