  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. Nitric oxide in experimental sepsis

    Författare :Peter Dahm; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intensive care; Nitric oxide; Sepsis; NO inhalation; Endotoxin; Acute lung injury; ARDS; Nitric oxide synthase; L-NMMA; L-NAME; Anestesiologi; Anaesthesiology; Pigs; intensivvård;

    Sammanfattning : Nitric oxide (NO) is important in the control of blood pressure and organ perfusion. In septic shock, NO produced by inducible NO-synthase (NOS) has been claimed to mediate pathological vasodilation and cell injury, while NO produced by constitutive NOS may be protective in counteracting hypoperfusion and organ injury.

  4. 3. Heme-copper oxidases and nitric oxide : Reaction mechanisms and supercomplex formation

    Författare :Ingrid Albertsson; Pia Ädelroth; Alessandro Giuffrè; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Heme-copper oxidase; nitrite reductase; nitric oxide reductase; nitric oxide; supercomplex; Paracoccus denitrificans; denitrification pathway; proton transfer pathway; C-type oxidase; Helicobacter pylori; Biochemistry; biokemi;

    Sammanfattning : In the denitrification process where nitrate is stepwise reduced to nitrogen gas, the toxic molecule nitric oxide (NO) is formed as an intermediate. Nitric oxide is produced by the enzyme cd1 Nitrite reductase (cd1NiR) by reduction of nitrite and is later reduced to nitrous oxide by nitric oxide reductase (cNOR). LÄS MER

  5. 4. Inhaled Nitric Oxide Therapy : Non-response and Rebound Response

    Författare :Luni Chen; Eddie Weitzberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; nitric oxide inhalation; rebound response; non-response; endothelin-1; COX inhibitor; prostaglandin; ARDS; endotoxin; oleic acid; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; Clinical Physiology; klinisk fysiologi;

    Sammanfattning : Therapeutic inhaled nitric oxide (INO) has proved beneficial in patients with pulmonary hypertension. However, around 30-40% of the patients are non-responders to this therapy, and a life-threatening rebound response may occur during attempts to withdraw INO. LÄS MER

  7. 5. Endogenous Nitric Oxide Production and Pulmonary Blood Flow : during different experimental lung conditions

    Författare :Manja Nilsson; Filip Fredén; Kristina Hambraeus-Jonzon; Göran Hedenstierna; Eddie Weitzberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nitric oxide; pulmonary blood flow; endotoxin; nitric oxide inhalation; endothelin; hypercapnia; acidosis; lavage-induced lung injury; Anaesthetics and intensive care; Anestesiologi och intensivvård; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : Nitric oxide (NO) is an important regulator of pulmonary blood flow and attenuates hypoxic pulmonary vasoconstriction (HPV). Nitric oxide is synthesized enzymatically in a number of tissues, including the lungs, and can also be generated from reduction of nitrite during hypoxia and acidosis. LÄS MER
