  1. 1. Vascular remodeling in pulmonary hypertension

    Author : Ya-Ting Chang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Pulmonary hypertension (PH) is a progressive obliterative vasculopathy with multifactorial etiology and high mortality rate. Endothelial dysfunction, excessive vascular remodeling, inflammation and in situ thrombosis contribute to increased vascular resistance and gradual occlusion of pulmonary vessels. READ MORE

  2. 2. MR Imaging of Congenital Heart Disease at 0.3 T

    Author : Nils Malmgren; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic Resonans Imaging; Congenital Heart Defects; Imaging parameters; Surface coils; Complex Congenital Heart Defects; Postoperative; Pulmonary vessels.;

    Abstract : The aim of this study was to systematically evaluate the potential of static MR Imaging in congenital heart disease. As low field equlpment was first avaliable, and contlnues to be used, the experienee with this type of imager is reported. Accurate parameter setting is of the greatest importance for efficient cardiac scanning. READ MORE

  3. 3. In the hands of ohm : hemodynamic aspects in pulmonary hypertension

    Author : Erik Tossavainen; Per Lindqvist; Michael Henein; Stefan Söderberg; Peter Eriksson; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; kardiologi; Cardiology;

    Abstract : Congestive heart failure (CHF) is one of the most challenging diseases in terms of health care demand and mortality, in the western world. Despite major breakthroughs in the fields of diagnosis and treatment over the three last decades, the management of CHF still remains challenging. READ MORE

  4. 4. Endothelin in the pulmonary circulation with special reference to hypoxic pulmonary vasoconstriction

    Author : Peter Holm; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; bosentan; BMS-182874; ; BQ-123; BQ-788; endothelin; endothelium; hypoxia; hypoxic pulmonary vasoconstriction; pulmonary hypertension; receptor antagonism; TBC 11251.;

    Abstract : Endothelin in the pulmonary circulation with special reference to hypoxic pulmonary vasoconstriction Peter Holm A number of substances originating from the pulmonary endothelium have recently been found to be involved in the regulation of pulmonary vascular tone. Accumulating evidence suggests that endothelial dysfunction contributes to pulmonary hypertension, an important clinical problem often associated with hypoxemia. READ MORE

  5. 5. Hypoxic pulmonary vasoconstriction and nitric oxide

    Author : Kristina Hambraeus Jonzon; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; hypoxia; pulmonary vasoconstriction; regional pulmonary bloodflow; stimulus-response; nitric oxide; blood-borne distant effects; nitric oxide synthase activity; inhaled; exhaled; non-enzymatic;

    Abstract : Hypoxia causes pulmonary vasoconstriction (HPV), improving oxygenation by redistribution of the pulmonary blood flow to better oxygenated lung regions. HPV is intrinsic to the pulmonary vascular smooth muscle cell, but can be modulated by several vasoactive substances, as for example endothelium derived nitric oxide (NO) and endothelin-1 (ET-1).
