  2. 1. Human muscle spindles : complex morphology and structural organisation

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

    Abstract : 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. READ MORE

  4. 2. Cross transfer effects after unilateral muscle overuse : an experimental animal study about alterations in the morphology and the tachykinin system of muscles

    Author : Yafeng Song; Per Stål; Sture Forsgren; Fawzi Kadi; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; Triceps surae; overuse; contralateral; muscle; muscle fiber; MyHC; capillary; tachykinin; substance P; NK-1R; inflammation; anatomi; Human Anatomy;

    Abstract : Unilateral exercise can produce certain contralateral strength effects. Deleterious events can be cross-transferred as well, as illustrated by a strict symmetry in some chronic inflammatory diseases. READ MORE

  5. 3. Skeletal muscle fiber types in man : With special reference to anabolic signaling and mitochondrial bioenergetics

    Author : Sebastian Edman; William Apro; Filip J Larsen; Abram Katz; Leigh Breen; Gymnastik- och idrottshögskolan; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mTORC1; THRIFTY; fiber type identification; muscle growth; aging; sarcopenia; mitochondrial function; oxphos; metabolism; Medicin Teknik; Medicine Technology;

    Abstract : Human skeletal muscle consists of a mixture of slow-twitch (type I) and fast-twitch (type II) fibers. The type I fibers are endurance-oriented, with a metabolic system and infrastructure that supports aerobic metabolism. READ MORE

  6. 4. Tendon transfer mechanics and donor muscle properties : implications in surgical correction of upper limb muscle imbalance

    Author : Eva Pontén; Bertil Romanus; Umeå universitet; []
    Keywords : laser diffraction; sarcomere length; tendon transfer; spasticity; muscle morphology; myosin heavy chain; capillary; rabbit; human; cerebral palsy; stroke; handkirurgi; hand surgery;

    Abstract : Tendon transfer surgery is used to improve the hand function of patients with nerve injuries, spinal cord lesions, cerebral palsy (CP), stroke, or muscle injuries. The tendon of a muscle, usually with function opposite that of the lost muscle function, is transferred to the tendon of the deficient muscle. READ MORE

  7. 5. Intensive Care Unit Muscle Wasting : Skeletal Muscle Phenotype and Underlying Molecular Mechanisms

    Author : Sudhakar Reddy Aare; Larsson Lars; Rooyackers Olav; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acute quadriplegic myopathy; gene expression; myosin; heat shock proteins; mechanical ventilation; myostatin; sepsis; corticosteroids; diaphragm; Clinical Neurophysiology; Klinisk neurofysiologi;

    Abstract : Acute quadriplegic myopathy (AQM), or critical illness myopathy, is a common debilitating acquired disorder in critically ill intensive care unit (ICU) patients characterized by generalized muscle wasting and weakness of limb and trunk muscles. A preferential loss of the thick filament protein myosin is considered pathognomonic of this disorder, but the myosin loss is observed relatively late during the disease progression. READ MORE
