  1. 6. Respiratory burst and severity of demyelinating diseases

    Författare :Natalia Mossberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurologi; immunologi; Guillain-Barré; Multiple sclerosis; respiratory burst;

    Sammanfattning : Multiple sclerosis (MS) and the Guillain-Barré syndrome (GBS) are tissue-specific inflammatory diseases of the central and the peripheral nervous system, respectively. A contemporary analysis infers that these are complex autoimmune disorders. LÄS MER

  3. 7. Respiratory Sinus Arrhythmia and Emotion : Effects of pictorial stimuli and state anxiety

    Författare :Peter Jönsson; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; state anxiety; emotion; HRV; heart rate variability; RSA; Respiratory sinus arrhythmia; Psykologi;

    Sammanfattning : Respiratory sinus arrhythmia (RSA) refers to heart rate variations due to respiration, which results from parasympathetic nervous system activity mediated via the tenth cranial nerve, the vagus. Thus, the magnitude of RSA is considered as an index of cardiac vagal tone. This thesis explored RSA during emotional responding in healthy women and men. LÄS MER

  4. 8. Health-related aerosol particle studies, respiratory tract deposition and indoor source identification

    Författare :Jakob Löndahl; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aerosol particle; health; ultrafine particles; nanoparticle; deposition; respiratory tract; Fysicumarkivet A:000;

    Sammanfattning : Aerosol particles have, since Classical Antiquity, been linked to adverse effects on human health. It is estimated that the particles in urban air pollution causes 100 000 deaths in Europe each year, whereof 5 000 in Sweden. LÄS MER

  5. 9. Spirodynamics. New methods for continuous monitoring of respiratory mechanics in ventilator-treated patients

    Författare :Sigurbergur Kárason; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Monitoring; Respiratory mechanics; Mechanical ventilation; Compliance; Alveolar pressure; Dynostatic algorithm; ALI; ARDS; Model; Human.;

    Sammanfattning : Introduction: Ventilator treatment is often life-saving but has the inherent risk of causing damage to lung tissues. Overdistension and repetitive collapsing/opening of alveoli should be avoided. Monitoring of respiratory mechanics has a central role in accomplishing this. LÄS MER

  7. 10. Structure of the distal lung studied with inhaled nanoparticles

    Författare :Madeleine Petersson Sjögren; Metalund; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Techniques able to detect impairments in the distal human lung are lacking. Since inhaled nanoparticles are predominantly deposited in the acini, their deposition can be used to derive structural properties of the region. Intheory, structural enlargements in the distal lung imply that less inhaled nanoparticles deposit there. LÄS MER
