  1. 36. Every breath you take every move you make. Studies on Asthma and Sports in Adolescent Athletes

    Författare :Kerstin Romberg; allergologi och palliativ medicin Lungmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adolescence; asthma; airway hyper-reactivity; mannitol provocation; exercise challenge; CC16; gender; life style; quality of life;

    Sammanfattning : Asthma and allergies are common diseases in adolescents and have increased during the last few decades. All elite level sports activities result in increased risk of asthma and rhinitis regardless of sport practised. LÄS MER

  3. 37. Capturing the breath of the heart by magnetic resonance imaging : five-dimensional cardio-respiratory resolved cine imaging during free breathing

    Författare :Karen Holst; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cardiac imaging with cardiovascular magnetic resonance has the advantage of enabling dynamic visualizations, several quantifiable measures, and good soft-tissue contrast. However, a major drawback is the need for breath holding during many acquisitions to limit motion artifacts. LÄS MER

  4. 38. Exahaled NO and small airway function in asthma and cystic fibrosis

    Författare :Christina Keen; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; asthma; exhaled NO; children; cystic fibrosis; flow independent exhaled nitric oxide; multiple breath inert gas washout; polyunsaturated fatty acids;

    Sammanfattning : Background: Asthma and cystic fibrosis (CF) are chronic inflammatory airway disorders known to involve the peripheral airways. Non-invasive tests sensitive to peripheral airway function and inflammation are therefore of high priority. LÄS MER

  5. 39. Severe hypoxemia during apnea in humans : influence of cardiovascular responses

    Författare :Peter Lindholm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Diving response; breath holding; bradycardia; vasoconstriction; hypoxia;

    Sammanfattning : When a diving human holds his or her breath, the heart beat slows and the blood vessels constrict in large portions of the body. In diving mammals such as seals, similar responses effectively conserve oxygen for the brain, enabling them to dive very deep and to stay underwater for a long time. LÄS MER

  7. 40. Diagnostic methods in helicobacter pylori infection : development, evaluation and application

    Författare :Ann-Sofie Jansson Rehnberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :H. pylori; Urea Breath Test; Serology; Bleeding disorder; Nitric oxide;

    Sammanfattning : Aim: To develop, evaluate and apply diagnostic methods for H. pylori infection. Materials and Methods: An in-house Urea Breath Test (UBT) was developed and evaluated in three different settings, using serology by ELISA and immunoblot as gold standard. Further, the Heliprobe was evaluated as an alternative diagnostic device. LÄS MER
