  1. 16. Effects of ageing and training on the human heart

    Författare :Frederic Bouvier; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Ageing; endurance training; exercise capacity; myocardial perfusion scintigraphy; ejection fraction; left ventricular end-diastolic volume; ventricular arrhythmias and heart rate variability;

    Sammanfattning : The aim of the present studies was to evaluate the effects of ageing and endurance training on the human heart. One hundred and twelve healthy subjects, athletes and non-athletes, between 20 and 80 years of age and two master athletes between 70 and 80 years of age with previous myocardial infarction were investigated.

  3. 17. Atopic dermatitis and distress

    Författare :Saly Mustafa Abdelhadi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Atopic dermatitis (AD) is a chronic, inflammatory skin condition characterized by itching, redness, and skin lesions, affecting approximately 10–20% of children and 1–3% of adults worldwide. Distress associated with AD can negatively impact quality of life, work, and daily activities. LÄS MER

  4. 18. Heat shock proteins in exercised human skeletal muscle

    Författare :Mattias Folkesson; Fawzi Kadi; Britta Wåhlin-Larsson; Robert Kruse; Barbara Wessner; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endurance training; Resistance training; Muscle Fibre Type; Electrical Pulse Stimulation; Muscle Hypertrophy;

    Sammanfattning : Exercise is considered as an important stressor accompanied by concerted molecular and cellular changes leading to adaptations at the level of skeletal muscle size and function. An important protein family produced by cells in response to stressful conditions is the heat shock proteins (HSPs). LÄS MER

  5. 19. Beat-to-beat variability of QRS amplitude and heart rate in ischemic heart disease : diagnostic potentials

    Författare :Inger Hagerman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :autonomic blockade; beat-to-beat variability; chaos; coronary arterydisease; correlation dimension; dobutamine; ECG; electrical heterogeneity; fractal dimension; heart rate variability; Lyapunov exponent; nonlinear; QRSvariance; surrogate data;

    Sammanfattning : The diagnostic potential of beat-to-beat QRS amplitude variability in patients with coronary artery disease (CAD) was evaluated with variance ECG and compared to exercise stress test and myocardial scintigraphy (SPECT). Two high prevalence populations of 199 and 166 patients each were investigated. LÄS MER

  7. 20. Studies of platelet function, and effects of aspirin and clopidogrel treatment

    Författare :Christina Perneby; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Antiplatelet therapy with aspirin and clopidogrel is a cornerstone in cardiovascular prevention and lowers cardiovascular mortality and morbidity in patient with coronary artery disease (CAD). Mental stress and physical exertion can trigger acute coronary events and prothrombotic responses to stress may contribute to such triggering. LÄS MER
