  1. 1. Exercise-induced muscle soreness : a qualitative and quantitative study of human muscle morphology and function

    Författare :Jan Fridén; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human; exercise; exertion; eccentric contractions; muscles; muscle strength; muscle soreness; fibre types; myofibrils; muscle proteins; histocy to chemistry; ultrastructure; stereology;

    Sammanfattning : Exercise-induced muscle soreness is characterized by stiffness, tenderness and pain during active movements and weakness of the affected musculature the days after unusually or particularly heavy work. The most pronounced subjective symptoms do not arise immediately but rather between a couple of hours to some days after the exercise (a delayed-onset of muscle soreness), the intensity of pain is greatest about 48 hours after the work.

  2. 2. Satellite cells in human skeletal muscle : molecular identification quantification and function

    Författare :Mona Lindström; Lars-Eric Thornell; Hannu Kalimo; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; satellite cell markers; NCAM; Pax7; MyoD; myogenin; DLK1 FA1; c-Met; human skeletal muscle; immunohistochemistry; muscle growth; muscle hypertrophy; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi; anatomi; Human Anatomy;

    Sammanfattning : Skeletal muscle satellite cells located between the plasma membrane and the basal lamina of muscle fibres, could for many years, only be studied in situ by electron microscopy. The introduction of immunohistochemistry and the discovery of molecular markers of satellite cells then made them accessible for light microscopic studies and a wealth of information is today available.

  3. 3. Muscle function in Juvenile Idiopathic Arthritis : A two-year follow-up

    Författare :Hans Lindehammar; Lars Larsson; Linköpings universitet; []
    Nyckelord :AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; arthritis; juvenile rheumatoid; physiopathology; muscle; skeletal; pathology; physiopathology; Muscular atrophy; etiology; physiopathology; arthritis; juvenile rheumatoid; complications; Medicine; Medicin;

    Sammanfattning : This is a study of muscle function in Juvenile Idiopathic Arthritis (JIA). Rheumatoid arthritis (RA) is a disease that primarily affects the synovial membrane of joints. Muscle weakness, atrophy and pain occur in adult RA. This may be a consequence of joint pain, stiffness and immobility. LÄS MER

  4. 4. Spatio-temporal processing of surface electromyographic signals : information on neuromuscular function and control

    Författare :Christer Grönlund; Leif Sörnmo; Umeå universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; EMG; multichannel surface electromyography; motor unit action potentials; conduction velocity; muscle architecture; signal quality; spatial distributions; synchronization; muscle function; motor control; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

    Sammanfattning : During muscle contraction, electrical signals are generated by the muscle cells. The analysis of those signals is called electromyography (EMG). The EMG signal is mainly determined by physiological factors including so called central factors (central nervous system origin) and peripheral factors (muscle tissue origin). LÄS MER

  5. 5. Vibration-induced muscle injury in the hand - experimental and clinical studies

    Författare :Lars Necking; Malmö Handkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatologi; Surgery; muscle morphometry; intrinsic hand muscle; muscle strength; muscle injury; hand weakness; Vibration exposure; hand-arm vibration syndrome; orthopaedics; traumatology; Kirurgi; ortopedi;

    Sammanfattning : Exposure to vibration is known to cause vasospastic white fingers and/or sensorineural symtoms such as numbness and tingling in fingers and/or musculoskeletal disorders such as reduction in muscle force, fatigue and reduced endurance. Classifications for the vasospastic and sensorineural symptoms are established. LÄS MER
