  1. 11. Prevalence and incidence of and risk factors for asthma and exercise-induced laryngeal obstruction in elite endurance athletes

    Författare :Tommie Irewall; Nikolai Stenfors; Anne Lindberg; Estelle Naumburg; James Hull; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; asthma; exercise-induced laryngeal obstruction; EILO; continuous laryngoscopy during exercise test; CLE; prevalence; risk factors; incidence; athletes; skiers; endurance athletes; Sports Medicine; idrottsmedicin; lungmedicin; Lung Medicine; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Sammanfattning : Background: Asthma is highly prevalent in endurance athletes, but we lack up-to-date information on the prevalence and incidence of asthma in cross-country skiers. Exercise-induced laryngeal obstruction (EILO) is an important differential diagnosis to exercise-induced asthma, and its symptoms can mimic asthma. LÄS MER

  3. 12. Adjuncts to the Conventional 12-Lead ECG: Assessment of High-Frequency QRS Components and Additional Leads

    Författare :Elin Trägårdh; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heart disease; Physiology; Fysiologi; Cardiovascular system; Kardiovaskulära systemet; myocardial infarction; 16-lead ECG; electrocardiogram; 24-lead ECG; HF-QRS;

    Sammanfattning : The standard 12-lead electrocardiogram (ECG) is one of the most commonly used methods for diagnosing heart disease. Standard ECG is not always optimal, however, and new ECG methods can provide additional information. Analysis of high-frequency QRS components (HF-QRS) has been shown to increase the diagnostic performance of the ECG. LÄS MER

  4. 13. Heart and lung function - in health and disease : methodological studies in clinical physiology

    Författare :Sofia Erelund; Nina Sundström; Urban Wiklund; Sandra Arvidsson; Bengt Johansson; Carl-Johan Carlhäll; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; clinical physiology; reference materials; ECG; dynamic spirometry; HRV; rheumatoid arthritis; cardiovascular disease; ischemic heart disease; Clinical Physiology; klinisk fysiologi;

    Sammanfattning : The human heart and lungs constitute an intricate and dynamic system. Various clinical physiological examinations can be used to evaluate cardio-pulmonary function and identify abnormalities. Thus, it is important to understand how normal physiology presents, to be able to identify pathological findings. LÄS MER

  5. 14. Seagrasses in warming oceans : physiological and biogeochemical responses

    Författare :Rushingisha George; Mats Björk; Martin Gullström; Teresa Alcoverro Pedrola; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Global warming; greenhouse gas; warming oceans; temperate; tropical; coastal waters; Western Indian Ocean WIO ; tidal variability; seagrass; photosynthesis; respiration; photorespiration; biogeochemical processes; sulphide; methane; nitrous oxide; carbon dioxide; Plant Physiology; växtfysiologi;

    Sammanfattning : The exponential increase of atmospheric greenhouse gas concentrations over the past 50 years has caused a rise in the global average temperature by more than 1ºC above pre-industrial levels. Ninety-three percent of this heat energy has been absorbed and stored by the oceans, increasing their temperatures, particularly in surface waters. LÄS MER

  7. 15. Proteome Profiling of Strawberry and Characterization of a Bet v 1-Homologous Allergen

    Författare :Rikard Alm; Biokemi och Strukturbiologi; []

    Sammanfattning : Strawberry (Fragaria ananassa) is an economically important crop, and recognised as an important source of antioxidants and bioactive compounds with health promoting effects. Yet increased incidence of allergy puts a limit to the choice of food for an increasing percentage of the population. LÄS MER
