  1. 1. Myonuclear Organization and Regulation of Muscle Contraction in Single Muscle Fibres : Effects of Ageing, Gender, Species, Endocrine Factors and Muscle Size

    Författare :Rizwan Qaisar; Lars Larsson; Jo Bruusgaard; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; single muscle cells; muscle nuclei; specific force; species; hypertrophy; mammals; ageing; gender; Physiology; Fysiologi;

    Sammanfattning : The skeletal muscle fibre is a syncitium where each myonucleus regulates the gene products in a finite volume of cytoplasm i.e., the myonuclear domain (MND). LÄS MER

  3. 2. Heat shock proteins in exercised human skeletal muscle

    Författare :Mattias Folkesson; Fawzi Kadi; Britta Wåhlin-Larsson; Robert Kruse; Barbara Wessner; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endurance training; Resistance training; Muscle Fibre Type; Electrical Pulse Stimulation; Muscle Hypertrophy;

    Sammanfattning : Exercise is considered as an important stressor accompanied by concerted molecular and cellular changes leading to adaptations at the level of skeletal muscle size and function. An important protein family produced by cells in response to stressful conditions is the heat shock proteins (HSPs). LÄS MER

  4. 3. Functional Studies of Genes Associated with Muscle Growth in Pigs and Hair Greying in Horses

    Författare :Lin Jiang; Leif Andersson; Kerstin Lindblad-Toh; Gerli Pielberg; Christopher Tuggle; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QTN; muscle development; IGF2; ZBED6; RNA-seq; ChIP-seq; myoblasts; pancreatic beta cells; Grey horse; melanoma; MITF; Biologi med inriktning mot molekylär cellbiologi; Biology with specialization in Molecular Cell Biology;

    Sammanfattning : Domestic animals have become very different from their wild ancestors during domestication and animal breeding. This provides a good model to unravel the molecular mechanisms underlying phenotypic variation. In my thesis I have studied genes affecting two important traits, leanness in pigs and hair greying-associated melanoma in horses. LÄS MER

  5. 4. Experimental studies of spinal mechanisms associated with muscle fatigue

    Författare :Ivana Kalezic; Vito Enrico Pettorossi; Umeå universitet; []
    Nyckelord :muscle fatigue; monosynaptic reflex; presynaptic inhibition; recurrent inhibition; fusimotor system; Fos-immunoreactivity; referral pain; kirurgi; Surgery;

    Sammanfattning : Muscle fatigue is ubiquitous in every day life.Muscle fatigue might be considered as an altered state of motor behaviour, which impairs motor performance. By contrast, muscle fatigue could also be considered a positive phenomenon, which protects muscle tissue from damage that might be incurred to it by overuse. LÄS MER

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

    Författare :Christer Grönlund; Leif Sörnmo; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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
