  1. 21. Endotracheal Suction a Reopened Problem

    Författare :Birgitta Almgren; Marieann Högman; Mats Sjöquist; Anders Larsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; Mechanical; ventilation; endotracheal; suction; lung; volume; loss; gas; exchange; Fysiologi; Physiology; Fysiologi;

    Sammanfattning : During mechanical ventilation, patients are connected to the ventilator by an endotracheal tube. The tube needs to be cleaned from mucus by suction, which can cause negative effects such as lung collapse, hypoxemia and desaturation. LÄS MER

  3. 22. Hamstring muscle strain

    Författare :Carl Askling; Alf Thorstensson; Tönu Saartok; Leif Swärd; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; Fysiologi; Hamstring injuries; MRI; palpation; recovery time;

    Sammanfattning : Background: Acute hamstring strains are common injuries in different sports. They are often serious, causing long rehabilitation times and a proneness for re-injury. LÄS MER

  4. 23. Neural circuits engaged in mastication and orofacial nociception

    Författare :Tuija Athanassiadis; K-G Westberg; Sten Grillner; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rhythmical jaw movements; central pattern generator; trigeminal system; rabbit; Rat; c-Fos; nociceptors; muscle pain; muscle spindle afferents; glutamate; Neurophysiology; Neurofysiologi; fysiologi; Physiology;

    Sammanfattning : A deeper understanding of both movement control and the effects of nociceptor inputs on our motor systems is critical for proper clinical diagnosis of musculo-skeletal dysfunctions and for development of novel rehabilitation schemes. In the jaw system, masticatory movements are produced by a central pattern generator (CPG) located in the brainstem. LÄS MER

  5. 24. Ion channels and electrical activity in vascular smooth muscle: Effects of calcium store depletion, cholesterol and cholesterol-lowering drugs

    Författare :Andreas Bergdahl; Kärlfysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysiologi; Physiology; statins; endothelin; cholesterol; caveolae; smooth muscle; TRP; Ca2 channels; SOC;

    Sammanfattning : Smooth muscle cells (SMCs) in the vessel wall contract to regulate blood flow and pressure, a function essential for normal circulation through tissues. On the other hand, migration and proliferation of SMCs are important factors in vascular disease, such as atherosclerosis and restenosis following surgical dilatation. LÄS MER

  7. 25. Tactile Sensory Control of Dexterous Manipulation in Humans

    Författare :Ingvars Birznieks; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; cutaneous sensibility; tactile afferents; fingertip force; grasp stability; human hand; manipulation; object shape; precision grip; sensorimotor control; coding; Fysiologi; Physiology; Fysiologi; fysiologi; Physiology;

    Sammanfattning : During dexterous manipulation with the fingertips, forces are applied to objects' surfaces. To achieve grasp stability, these forces must be appropriate given the properties of the objects and the skin of the fingertips, and the nature of the task. LÄS MER
