  1. 1. Adverse Muscle Composition : Revisiting Sarcopenia in General Population and Liver Disease using Magnetic Resonance Imaging

    Författare :Jennifer Linge; Mattias Ekstedt; Patrik Nasr; Martin Henriksson; Tommy Cederholm; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Sarcopenia - from the Greek words 'sarx' (flesh) and 'penia' (loss) - was, when coined in 1989, a term denoting the decline in muscle mass and strength that occurs with aging. Such definition implies everyone suffers from sarcopenia to varying degrees, which naturally makes studying sarcopenia challenging. LÄS MER

  3. 2. Quantitative Muscle Composition Analysis Using Magnetic Resonance Imaging

    Författare :Anette Karlsson; Magnus Borga; Anneli Peolsson; Janne West; Todd Parrish; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Muscle Composition; Muscle fat Infiltration; Magnetic Resonance Imaging;

    Sammanfattning : Changes in muscle tissue composition, e.g. decrease in volume and/or increase of fat infiltration, are related to adverse health conditions such as sarcopenia, inflammation, muscular dystrophy, and chronic pain. LÄS MER

  4. 3. 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

  5. 4. Fatty Acid Composition in Skeletal Muscle : Influence of Physical Activity and Dietary Fat Quality

    Författare :Agneta Andersson; Len Storlien; Uppsala universitet; []
    Nyckelord :Medical sciences; Skeletal muscle; phospholipids; triglycerides; fatty acids; physical activity; lipid peroxidation; dietary fat quality; n-3 polyunsaturated fatty acids; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Geriatrics; geriatrik;

    Sammanfattning : Insulin sensitivity is related to the fatty acid profile of skeletal muscle. The aim of this thesis was to investigate whether physical activity and dietary fat quality, independent of each other, influence the fatty acid composition of the skeletal muscle lipids. LÄS MER

  7. 5. Extra- and intrafusal muscle fibre type compositions of the human masseter at young age. : In perspective of growth and functional maturation of the jaw-face motor system

    Författare :Catharina Österlund; Per-Olof Eriksson; Lars-Eric Thornell; Per Stål; Malin Ernberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; jaw; limb; human; muscle; morphology; fibre type; myosin heavy chain; muscle spindle; Morphology; Morfologi; anatomi; Human Anatomy;

    Sammanfattning : Muscles control body posture and movement by extrafusal and intrafusal (muscle spindle) fibres. The purpose of this thesis was to provide insight into the muscular basis for human jaw function at young age. LÄS MER
