  1. 16. Effects of physical exercise on coronary and peripheral vascular function. An integrative physiological study from rat to man

    Författare :Ulrika Hägg Samuelsson; Göteborgs universitet; []
    Nyckelord :exercise; endothelial function; coronary flow velocity reserve; colour Doppler echocardiography; oxidative stress; gene expression; stiffness; ultrasound biomicroscopy;

    Sammanfattning : Physical exercise is beneficial for the cardiovascular health. Numerous epidemiological studies reveal that physical activity reduces the risk of cardiovascular related death. Nevertheless, the underlying vessel wall specific physiological and molecular mechanisms still remain incompletely understood. LÄS MER

  3. 17. Vascular inflammation : implications for microvascular reconstructive surgery after irradiation

    Författare :Martin Halle; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Inflammation; irradiation; atherosclerosis; NF-kappaB; nitric oxide; microvascular reconstructive surgery;

    Sammanfattning : Better treatment has led to a rapidly increasing population of cancer survivors. A growing body of clinical evidence has shown that radiotherapy is associated with adverse effects on the cardiovascular system, such as myocardial infarction and stroke, depending on the previous treatment site.

  4. 18. Foregut motility disorders : a clinical and experimental study

    Författare :Ann Kjellin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Objective: To investigate some clinical aspects and treatment modalities of foregut motility disorders and to experimentally explore some mechanisms involved. Special emphasis has been put on elucidating and evaluating different treatment modalities. LÄS MER

  5. 19. Improved bioenergetic recovery during experimental ischemia and reperfusion by irradiation

    Författare :Ann Lindgård; Göteborgs universitet; []
    Nyckelord :energy metabolism; skeletal muscle; monocyte; ischemia; reperfusion; NMR; singlet oxygen energy; light; LED;

    Sammanfattning : Prolonged ischemia and reperfusion frequently occur during clinical operations. The bioenergetic status decreases during ischemia and reactive oxygen species (ROS) are formed during reperfusion, which may lead to irreversible tissue injury. LÄS MER

  7. 20. On the role of nitric oxide in lower urinary tract disease

    Författare :Lotta Renström Koskela; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Nitric oxide (NO) is an important biological molecule with a variety of functions. Among other, it is a signalling molecule capable of inducing smooth muscle relaxation and vasodilatation, it regulates proliferation, can induce apoptosis and act as an effector molecule in host defence reactions and in immune regulatory processes.
