  1. 1. Sympathetic function in cardiac disorders.Upon cardio-renal sympathetic activity and effects of nitroglycerin in human heart failure

    Författare :Magnus Petersson; Göteborgs universitet; []
    Nyckelord :heart failure; renovascular hypertension; sympathetic nervous system; noradrenaline; mortality; renal circulation; cardiovascular physiology; baroreflex; nitroglycerin;

    Sammanfattning : This study explores pathophysiological mechanisms and prognostic implications of sympathetic activation in patients with atherosclerotic renovascular hypertension (RVH) and with chronic heart failure (CHF). Hitherto, it is unknown whether cardiac sympathetic activation is present in patients with RVH, the presence of which could relate to the increased cardiovascular mortality observed in this disorder.

  3. 2. Nitric oxide generation from nitroglycerin and other no-donors measured in the lung and studies on nitrate tolerance in the cardiovascular system

    Författare :Per Agvald; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Exhaled; nitric oxide; nitroglycerin; nitrite; temperature; tolerance; hypoxia;

    Sammanfattning : Nitroglycerin (GTN) and compounds referred to as nitrovasodilators or NOdonors are frequently used in the treatment of ischemic heart disease. The common mode of action for these drugs is liberation of nitric oxide (NO). Nitric oxide evokes relaxation of smooth muscle through activation of guanylate cyclase with subsequent formation of eGMP. LÄS MER

  4. 3. Reglerad sprängkraft : dynamiten, staten och den svenska civila sprängmedelsindustrin 1858-1950

    Författare :Josefin Sabo; Lena Andersson-Skog; Fredrik Olsson-Spjut; Susanna Fellman; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic history; dynamite; the Swedish civilian explosives industry; Alfred Nobel; regulations; regulatory capture; government-market relations; Nitroglycerin Aktiebolaget NA ; the Inspectorate of Explosives and Flammables; ekonomisk historia; Economic History;

    Sammanfattning : The development of new innovations in explosives was an important part of the industrialization process from the mid-nineteenth century. The establishment of the world´s first nitroglycerin factory – Nitroglycerin Aktiebolaget (NA) in Stockholm in 1864 started a process replacing gunpowder with nitroglycerin and from 1868 by the safer invention dynamite.

  5. 4. Arterial pulse wave analysis. With special reference to vasoactive and anaesthetic drugs and to heart lung interactions

    Författare :Staffan Söderström; Göteborgs universitet; []
    Nyckelord :pulse; blood pressure physiology; hypertension; aged; vasodilation; ventricular function; left; nitroglycerin; coronary disease; artificial respiration; fentanyl.;

    Sammanfattning : In the young systolic arterial pressures (SAP) are higher in the radial artery than in the proximal aorta. Due to increased large artery stiffness and early pulse wave reflection aortic SAP increases more with age than peripheral SAP. LÄS MER

  7. 5. Nitric oxide donors in labor management

    Författare :Maria Bullarbo; Göteborgs universitet; []
    Nyckelord :cervical ripening; labor induction; nitric oxide donor; retained placenta;

    Sammanfattning : ABSTRACT Nitric oxide donors in labor management Maria Bullarbo Department of Obstetrics and Gynecology Institute of Clinical Sciences Background: Nitric oxide (NO), a free radical with ultra-short half-life synthesized from L- arginine by the enzyme nitric oxide synthase (NOS), is in the human involved in many physiological and pathophysiological processes, including different reproductive processes. During pregnancy NO is produced endogenously in the human uterine cervix and placenta. LÄS MER
