  1. 1. Mechanisms of stretch-induced growth and contractile differentiation in vascular smooth muscle

    Författare :Asad Zeidan; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysiologi; Physiology; SM22a; ERK1 2; caveolae; stretch; Smooth muscle; differentiation;

    Sammanfattning : Vascular smooth muscle can adapt to increased intraluminal pressure by remodelling and hypertrophy, as seen in hypertension. The molecular mechanisms responsible for this are still incompletely characterized. LÄS MER

  3. 2. Classification of muscle stretch receptor afferents in humans

    Författare :Benoni B. Edin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Muscle spindles; Golgi tendon organs; Classification of muscle receptors; Microneurography; Human hand; Stretch sensitization; Voluntary contraction; Static position sensitivity; Fusimotor control;

    Sammanfattning : The response patterns of human stretch receptors in the finger extensor muscles of the forearm were studied using the microneurography technique. Single-unit recordings were obtained from one-hundred and twenty-four afferents. LÄS MER

  4. 3. Vascular smooth muscle mechanotransduction and plasticity-the role of microRNA, calcium signaling and actin polymerization

    Författare :Karolina Turczynska; Kärlfysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PYK2; actin polymerization; calcium; microRNA; stretch;

    Sammanfattning : Smooth muscle cells residing in the blood vessel media are constantly exposed to mechanical forces exerted by the intraluminal pressure. The smooth muscle senses and adapts to mechanical forces by activation of multiple signaling pathways and cytoskeletal rearrangements. LÄS MER

  5. 4. Investigation of a prototype industrial gas turbine combustor using alternative gaseous fuels

    Författare :Ivan Sigfrid; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; Gas Turbine; Laminar flame speed; Stretch; Lean blowout; Emissions;

    Sammanfattning : In this thesis, the effect of alternative gaseous fuels, with high hydrogen content and lower calorific value, on gas turbine combustion was investigated experimentally. The aim of the investigation was to find operational limitations for an experimental burner and to supply data for validation of computational fluid dynamics (CFD). LÄS MER

  7. 5. Biochemical and biomechanical modulation of the in vitro retina

    Författare :Linnéa Taylor; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Retina; in vitro; modulation; biomechanics; glutamate; GDNF; stretch; Müller cells; Photoreceptors; gliosis;

    Sammanfattning : The porcine retinal explant culture paradigm offers the possibility to study retinal health, disease and development independently from the surrounding tissues of the eye. Retina-intrinsic effects of molecular and mechanical cues on the isolated retinal sheet can thus be studied with great precision. LÄS MER
