  1. 1. Extraocular Muscles in Amyotrophic Lateral Sclerosis

    Författare :Anton Tjust; Fatima Pedrosa Domellöf; Mona Lindström; Thomas Brännström; Eva Hedlund; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ALS; EOM; Satellite cells; innervation; neuromuscular disease; neurodegenerative disease; anatomi; Human Anatomy;

    Sammanfattning : Amyotrophic lateral sclerosis (ALS) is an incurable neurodegenerative disease of motor neurons characterized by muscle paralysis and death within 3-5 years of onset. However, due to unknown mechanisms, the extraocular muscles (EOMs) remain remarkably unaffected. LÄS MER

  3. 2. Optical Measurements of Rolling Friction Coefficients

    Författare :Yiling Li; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : This thesis presents an optical method to measure the rolling friction coefficientsfor balls rolling freely on a cylindrical surface. Two different models of a ball rollingfreely on a cylindrical surface are established, one is an analytical model and the otheris a numerical model derived from Lagrange equation. LÄS MER

  4. 3. Human extraocular muscles : molecular diversity of a unique muscle allotype

    Författare :Daniel Kjellgren; Fatima Pedrosa-Domellöf; Lars-Erik Thornell; Lillemor Wachtmeister; John Porter; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ophtalmology; extraocular; muscle; myosin; protein c; laminin; serca; immunocytochemistry; human; Oftalmiatrik; Ophtalmology; Oftalmologi; oftalmiatrik; Ophtalmology;

    Sammanfattning : Introduction: The extraocular muscles (EOMs) are considered a separate class of skeletal muscle, allotype. Myosin is the major contractile protein in muscle. The myosin heavy chain (MyHC) isoforms are the best molecular markers of functional heterogeneity of muscle fibers. LÄS MER

  5. 4. Genetic studies of zebrafish muscles : clues to protection in muscle disease

    Författare :Nils Dennhag; Fatima Pedrosa Domellöf; Jonas von Hofsten; Tatjana Haitina; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; zebrafish; muscle; extraocular muscles; intermediate filaments; bioinformatics; genetics; CRISPR Cas9; oftalmiatrik; ophthalmology; cellforskning; cell research;

    Sammanfattning : Muscular dystrophies (MDs) are caused by dysregulation of over 40 proteins but commonly share features of muscle weakness, myofiber death and regeneration, loss of ambulation and premature death. A MD involves a broken link anywhere in the connection from extracellular matrix through the sarcolemma to the sarcomere. LÄS MER

  7. 5. Simulation of Electro-Optic Modulators by a Time-Domain Beam-Propagation Method

    Författare :Elin Solberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; time-domain beam-propagation method; finite element method; tensor products; computational electromagnetics; photonics; electro-optic modulators; finite element method;

    Sammanfattning : Electro-optic modulators (EOMs) are components which convert electric signals to optical ones. They are needed, e.g., at the transmitter end of fiber-optic communication systems and in time-stretch analog-to-digital converters. LÄS MER
