  1. 36. Pulmonary hypertension. Clinical and pathophysiological studies

    Författare :Nedim Selimovic; Göteborgs universitet; []
    Nyckelord :Pulmonary hypertension; Echocardiography; Right heart catheterisation; Pulmonary vascular resistance; Pulmonary function tests; Lung transplantation; Mortality on the waiting list; Vascular remodelling; Growth substances; Inflammation; Endothelin;

    Sammanfattning : Pulmonary hypertension (PH) is a common abnormality, most often associated with various cardiopulmonary diseases. Pulmonary arterial hypertension (PAH) is a devastating pulmonary vascular disease characterised by the proliferation of endothelial, smooth-muscle cells and fibroblasts. LÄS MER

  3. 37. 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).

  4. 38. Formation and properties of polyelectrolyte multilayers on wood fibres : influence on paper strength and fibre wettability

    Författare :Rikard Lingström; Lars Wågberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polyelectrolyte; multilayer; adsorption; reflectance; contact angle; dynamics; paper; mechanical properties; individual; wood fibre; Chemistry; Kemi;

    Sammanfattning : The work in this licentiate thesis examines the adsorption of polyelectrolyte multilayers (PEM) onto wood fibres as a new way to influence the properties of the fibre surfaces and hence the fibres. Fundamental aspects of PEM formation on wood fibres have been studied, and discussed in terms of paper strength and wood fibre wettability. LÄS MER

  5. 39. 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.

  7. 40. 3D visualization of vascular lesions and the role of versican in pulmonary arterial hypertension

    Författare :Christian Westöö; Kärlväggsbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pulmonary arterial hypertension; Synchrotron; Imaging; Phase-contrast; Plexiform; Versican;

    Sammanfattning : Pulmonary arterial hypertension (PAH) is a condition that leads to lethal right heart failure. Available treatments provide relief but are far from curative and the vascular remodeling in PAH has been difficult to decipher. LÄS MER
