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

    University dissertation from Umeå : Integrativ medicinsk biologi

    Author : Ingvars Birznieks; [2003]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mia Phillipson; Lena Holm; Henrik Sjövall; [2003]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Britt-Marie Sundblad; Bengt-Eric Skoogh; [2002]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jonas Appelberg; Göran Hedenstierna; Christer Janson; Karl Franklin; [2003]
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. Gastrointestinal mucosal protective mechanisms Mudolatory effects of Heliobacter pyroli on the gastric mucus gel barrier and mucosal blood flow in vivo

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Christer Atuma; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; mucus gel layer; mucosal blood flow; mucus thickness; chronic infection; rat; platelet activating factor; mast cell; nitric oxide; nitric oxide synthase; ketotifen; intra-vital microscopy; microelectrode; laser-Doppler flowmetry; L- NNA; Fysiologi och anatomi; MEDICINE Physiology and pharmacology; MEDICIN Fysiologi och farmakologi; Physiology; fysiologi;

    Abstract : The gastrointestinal mucus gel layer and blood flow are two important mechanisms for protection at the pre-epithelial and sub-epithelial levels, respectively. Helicobacter pylori might circumvent these mechanisms and elicit a chronic inflammatory response with consequent ulcers in the stomach and duodenum. READ MORE
