  1. 11. Characterization of ATP-dependent protein dynamics under native-like conditions

    Författare :Harsha Ravishankar; Magnus Andersson; Hans Wolf-Watz; Lise Arleth; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; proteins; membrane proteins; structural dynamics; ATPases; MD simulations; X-ray scattering; FTIR spectroscopy; ATP; TR-XSS; structural biology.; Biochemistry; biokemi;

    Sammanfattning : Proteins are biological macromolecules capable of accelerating biochemical reactions. To accomplish this, proteins undergo changes in their molecular structure. Advances in structural biology have resulted in ever-increasing numbers of high-resolution protein structures. LÄS MER

  3. 12. Molecular mechanisms in idiopathic inflammatory myopathies

    Författare :Mei Zong; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Myositis is a group of rare autoimmune diseases. Muscle weakness and fatigue are the dominant symptoms and inflammation with T cells and macrophages is a characteristic finding in muscle tissue. LÄS MER

  4. 13. Regulation of glucose transport and insulin-stimulated GLUT4 translocation in skeletal muscle

    Författare :Jorge E Rincón Viatela; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :skeletal muscle; glucose transport; insulin resistance; hyperglycaemia; steroid hormones; smoking; nicotine;

    Sammanfattning : Skeletal muscle represents about 40% of body mass and accounts for at least 80% of glucose disposal under insulin-stimulated conditions. Furthermore, GLUT4 transport protein is the primary component of the glucose transport system in skeletal muscle. LÄS MER

  5. 14. Pathogenic mechanisms in idiopathic inflammatory myopathies

    Författare :Cecilia Grundtman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Idiopathic inflammatory myopathies (IIMs) are chronic inflammatory disorders characterized by muscle weakness, by low muscle endurance, and by inflammation in skeletal muscle tissue. The pathogenesis and etiology of these conditions are yet not fully understood and several different mechanisms are likely to be involved. LÄS MER

  7. 15. Human muscle spindles : complex morphology and structural organisation

    Författare :Jing-Xia Liu; William K. Ovalle; Umeå universitet; []
    Nyckelord :human; muscle spindle; intrafusal fiber; aging; biceps brachii; deep muscles of the neck; MyHC; mATPase; SERCA; anatomi; Human Anatomy;

    Sammanfattning : Muscle spindles are skeletal muscle mechanoreceptors that mediate the stretch reflex and provide axial and limb position information to the central nervous system. They have been proposed to play a major role in the pathophysiology of muscle pain. LÄS MER
