  1. 1. Nitric oxide : An ally in extracorporeal circulation?

    Författare :Vilyam Melki; Jan Borowiec; Örjan Friberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Simulated extracorporeal circulation; Inflammation; Nitric oxide; Leukocyte activation; Staphylococcus aureus; Glyceryl trinitrate; Postoperative infection; Thorax Surgery; Thoraxkirurgi;

    Sammanfattning : Many complications associated with heart surgery are due to the negative effects of extracorporeal circulation (ECC). Some of these complications may be attributed to ECC-induced activation of inflammation and coagulation pathways. LÄS MER

  3. 2. Pulmonary Hypertension and the Nitric Oxide System

    Författare :Dan Henrohn; Gerhard Wikström; Ulla Lindqvist; John Pernow; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pulmonary hypertension; nitric oxide; ADMA; arginine; nitrate; nitrite; vardenafil; beetroot juice; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Pulmonary hypertension (PH) is a pathophysiological state associated with several medical conditions, leading to progressive rise in pulmonary vascular resistance (PVR) and right ventricular failure. The clinical PH classification encompasses five main World Health Organization (WHO) groups; pulmonary arterial hypertension (PAH), PH due to left heart disease, PH due to lung diseases and/or hypoxia, chronic thromboembolic PH, and PH with unclear multifactorial mechanisms.

  4. 3. New modes of improving ventilation and oxygenation in pulmonary hypertension and acute respiratory failure in newborns and children

    Författare :Sylvia Göthberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Inhaled nitric oxide; high frequency oscillatory ventilation; partial liquid ventilation; respiratory inductive plethysmography; follow-up study; pulmonary hypertension; congenital heart disease; acute respiratory failure; respiratory distress syndrome; persistent pulmonary hypertension of the newborn.;

    Sammanfattning : Pulmonary hypertension leading to hypoxemia is a potentially life-threatening condition in pediatric intensive care. Hypoxemia may also result from conditions not primarily related to pulmonary hypertension. LÄS MER

  5. 4. Vardenafil and methylarginines in pulmonary hypertension

    Författare :Anna Sandqvist; Gerhard Wikström; Jörn Schneede; Amrita Ahluwalia; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vardenafil; pulmonary hypertension; pharmacokinetics; haemodynamics; right heart catheterization; adenosine; dimethylarginines; phosphodiesterase type 5 inhibitors; endothelin receptor antagonists; klinisk farmakologi; Clinical Pharmacology;

    Sammanfattning : Background: Pulmonary hypertension (PH) is a rare condition characterized by endothelial dysfunction and vascular remodelling, leading to increased pulmonary vascular resistance (PVR) and right ventricular heart failure. Endothelial dysfunction is associated with an imbalance between vasoconstrictor compounds, such as endothelin and thromboxane A2, and vasodilator compounds, such as prostacyclin and nitric oxide (NO).

  7. 5. NO Effect on Inflammatory Reaction in Extracorporeal Circulation : Ex vivo Studies

    Författare :Mika Lahtinen; Jan Borowiec; Per Venge; Vibeke Videm; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Cardiac surgery; extracorporeal circulation; inflammatory reaction; NO; degranulation; neutrophil; eosinophil; basophil; complement; contact system; coagulation; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; Clinical Chemistry; klinisk kemi;

    Sammanfattning : Nitric oxide (NO) is expressed in inflammatory tissues. However, NO effects are controversial in inflammation; NO is described as acting in a dose dependent manner and possess both pro-inflammatory and anti-inflammatory properties. LÄS MER
