  1. 21. Cardiovascular risk factors and peripheral vascular function in lung transplant recipients

    Författare :Martin Silverborn; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :lung transplantation; cardiovascular risk factors; hypertension; arterial compliance; vascular resistance; endothelial function; endothelin-1;

    Sammanfattning : Objective: Cardiovascular disease is a major contributor to morbidity and mortality after organ transplantation. Development of cardiovascular risk factors, like hypertension, is common after transplantation. LÄS MER

  2. 22. Inhaled Nitric Oxide Therapy : Non-response and Rebound Response

    Författare :Luni Chen; Eddie Weitzberg; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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

  3. 23. Nitric oxide in experimental sepsis

    Författare :Peter Dahm; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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. 24. Experimental Studies of Endocrine Disrupting Compounds in Vascular Cells and Tissues

    Författare :Helén Andersson; Eva Brittebo; Malin Celander; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocrine disrupting compounds; endothelium; vascular toxicity; Toxicology; Toxikologi;

    Sammanfattning : Epidemiological evidence suggest that exposure to endocrine disrupting compounds (EDCs) is a risk factor for diseases that involves the cardiovascular system but we know little about the mechanisms whereby these compounds can cause injury in the vasculature. The aim of this thesis was to characterize the effects and mechanisms of some EDCs in vascular cells and highly vascularized tissues. LÄS MER

  5. 25. 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 :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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
