  1. 1. Tactile Sensory Control of Dexterous Manipulation in Humans

    Detta är en avhandling från Umeå : Integrativ medicinsk biologi

    Författare :Ingvars Birznieks; [2003]
    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; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi 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

  2. 2. Acid transport through gastric mucus A study in vivo in rats and mice

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mia Phillipson; Lena Holm; Henrik Sjövall; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; gastric acid; pH-sensitive microelectrode; mucus; mucosal blood flow; nitric oxide; intravital microscopy; laser Doppler flowmetry; Fysiologi; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi Fysiologi; Physiology; fysiologi;

    Sammanfattning : The gastric mucosa is frequently exposed to endogenously secreted hydrochloric acid of high acidity. Gastric mucosal defense mechanisms are arranged at different levels of the gastric mucosa and must work in unison to maintain its integrity. LÄS MER

  3. 3. Optimizing and evaluation of a methacholine provocation test with application in occupational research

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Britt-Marie Sundblad; Bengt-Eric Skoogh; [2002]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; Airway responsiveness; methacholine provocation; nitric oxide; eucapnic hyperventilation; organic dust; Fysiologi; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi Fysiologi; Physiology; fysiologi;

    Sammanfattning : We have developed a methacholine provocation method, which detects bronchial responsiveness in more than 80% of healthy subjects. The method enables us to detect differences in bronchial responsiveness within the normal range. With this method FEV1 and Gaw had similar sensitivity in detecting small differences in bronchial responsiveness. LÄS MER

  4. 4. Treatment effects with a mandibular advancement appliance and uvulopalatopharyngoplasty in obstructive sleep apnea -randomised controlled trials-

    Detta är en avhandling från Uppsala University Library

    Författare :Marie-Louise Walker-Engström; Elisabeth Hultcrantz; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; oral appliance; dental appliance; obstructive sleep apnea; UPPP; quality of life; somnography; randomised controlled trial; one-year follow-up; four-year follow-up; severe obstructive sleep apnea; Fysiologi; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi Fysiologi; Physiology; fysiologi;

    Sammanfattning : Enthusiasm for uvulopalatopharyngoplasty (UPPP) in the treatment of mild-to-moderate obstructive sleep apnea syndrome (OSAS) has declined in recent years, partly because of a lower success rate over time and partly because of adverse effects. In more severe cases, the patients are generally treated with nasal continuous positive airway pressure (CPAP). LÄS MER

  5. 5. Ventilation and Lung Volume During Sleep and in Obstructive Sleep Apnea

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Jonas Appelberg; Göran Hedenstierna; Christer Janson; Karl Franklin; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; Sleep; Ventilation; Sleep apnea syndromes; Snoring; Lung volume; Respiration; Computed tomography; Ventilatory response; Ventilation-perfusion; Airway closure; Fysiologi; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi Fysiologi; klinisk fysiologi; Clinical Physiology;

    Sammanfattning : Obstructive sleep apnea (OSA) appears to affect up to 5% of the population. The extent to what pulmonary function awake and during sleep relates to obstructive breathing and hypoxemia during sleep in these patients is unclear. LÄS MER
