  4. 13. 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

  5. 14. Neuropeptide Y Y1 receptor mechanisms in sympathetic vascular control

    Författare :Rickard E Malmström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Sympathetic vasoconstriction; neuropeptide Y1 Y; receptor antagonists; BIBP 3226; SR 120107A; ischaemia; pig.;

    Sammanfattning : It was demonstrated that the Y1 receptor was the predominant vascular neuropeptide Y (NPY) receptor in pig kidney and hind limb as exogenous and endogenous NPY evoked vasoconstrictor responses that were almost or totally abolished by the selective non-peptide Y1 receptor antagonist, BIBP 3226. Furthermore, renal vasoconstriction was evoked by NPY and a peptide Y1 agonist, but not by a Y 2 agonist, and these responses were strongly reduced by another non-peptide Y, receptor antagonist, SR 120107A.

  7. 15. The importance of endothelin-1 for vascular function in patients with atherosclerosis and healthy controls

    Författare :Felix Böhm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Acetylcholine; atherosclerosis; blood flow; circulation; coronary disease; endothelin; endothelium; kidney; liver; nitric oxide; patients; receptors; vasoconstriction.;

    Sammanfattning : Background: Atherosclerosis is associated with endothelial dysfunction, which is an early sign with prognostic implications in patients with coronary artery disease. Atherosclerosis is also associated with enhanced expression of the vasoconstrictor peptide endothelin-1 (ET-1). LÄS MER
