  1. 1. Levosimendan in early experimental sepsis: effects on the heart and hepatosplanchnic circulation

    Författare :Doris Cunha Goncalves; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; septic shock; myocardial oxygen consumption; myocardial dysfunction; levosimendan; endotoxin; contractility; catecholamines; calcium sensitizer; cardiotonic agents; splanchnic perfusion;

    Sammanfattning : Sepsis-related cardiovascular dysfunction associated with fluid-unresponsive tissue hypoperfusion might require inotropic treatment. This cardiovascular dysfunction seems to involve calcium desensitization and adrenergic unresponsiveness. LÄS MER

  3. 2. On angiotensin II receptor type 2 receptors in the small intestine

    Författare :Sara Ewert; Göteborgs universitet; Göteborgs universitet; Gothenburg University; Göteborgs universitet; Gothenburg University; []
    Nyckelord :renin-angiotensin; angiotensin; small intestine; mucosa; epithelium; AT1; AT2; bradykinin; BK2 receptor; nitric oxide; iNOS; smooth muscle; contractility;

    Sammanfattning : The endocrine renin-angiotensin system (RAS) is important in the regulation of extracellular fluid volume and systemic blood pressure in strenuous conditions such as hypovolemia. Also present locally in peripheral tissues, all components of RAS are expressed and have been shown to modulate development, cell growth and inflammation. LÄS MER

  4. 3. Left ventricular function's relation to load, experimental studies in a porcine model

    Författare :Roman A'roch; Michael Haney; Jan Poelaert; Lars-Åke Brodin; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heart function; preload; afterload; contractility; myocardial tissue velocity; speckle tracking; Anaesthetics and intensive care; Anestesiologi och intensivvård; Cardiology; kardiologi;

    Sammanfattning : Background: Loading conditions are recognized to influence ventricular function according to the Starling relationship for length/stretch and force.  Many modern echocardiographic parameters which have been announced as describing ventricular function and contractile status, may be confounded by uncontrolled and unmeasured load.

  5. 4. The Nitric Oxide and Renin-angiotensin II Systems in the Human Esophagus

    Författare :Anna Casselbrant; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Acid; nitric oxide; nitric oxide synthase; salivary secretion; renin-angiotensin; At1 receptor; AT2 receptor; mucosa; smooth muscle; contractility; peristaltic; high-pressure zone;

  7. 5. Cooling and dopamine

    Författare :Roger Roscher; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology; electrophysiology; cooling; Hypothermia; swine; lung transplantation; organ preservation; dopamine; circulation; contractility; oxygenation; intensive care; Anestesiologi; intensivvård;

    Sammanfattning : There is little knowledge about the circulatory effects of dopamine in hypothermia. Induced hypothermia has been shown to improve outcome in various settings. Hypothermia is also used for preservation of organs that are harvested for transplantation. LÄS MER
