  1. 6. ASPECTS OF FLUID THERAPY: An experimental study of the effects of systemic inflammation, microvascular permeability, blood pressure and plasma volume

    Författare :Maris Dubniks; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sepsis; activated protein C; SIRS; albumin; blood pressure; colloids; plasma volume; hypervolaemia; hypovolaemia; microcirculation; noradrenalin; permeability; prostacyclin;

    Sammanfattning : Adequate circulating blood volume is a prerequisite for circulatory stability. Fluid therapy aims at correcting hypovolaemia, and is an important part of the haemodynamic management of perioperative and critically ill patients. LÄS MER

  3. 7. Blood Flow variations in Large Arteries due to non-Newtonian rheology

    Författare :Stevin van Wyk; Laszlo Fuchs; Staffan Lundström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blood; Rheology; Viscosity; non-Newtonian; CFD; Bifurcations; Unsteadiness; Wall Shear Stress; Atherosclerosis;

    Sammanfattning : The blood is a complex fluid that contains, in addition to water, cells, macro-molecules and a large number of smaller molecules. The physical properties of the blood are therefore the result of non-linear interactions of its constituents, which are influenced by the local flow field conditions. LÄS MER

  4. 8. Fractional moving blood volume in fetal organs estimated using power Doppler ultrasound

    Författare :Edgar Hernandez-Andrade; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduction; andrology; gynaecology; Obstetrics; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet; fetal adrenal gland; fetal lung; radionuclear microspheres; fetal lamb; perfusion; fetus; Power Doppler ultrasound; fractional moving blood volume;

    Sammanfattning : Power Doppler ultrasound (PDU) is a sensitive technique to detect slow blood movement. The aim of the present study was to develop a standardized method for quantification of the PDU signals recorded from a specific region of interest (ROI) within fetal organs. LÄS MER

  5. 9. Exploring the heterogeneity of the hematopoietic stem and progenitor cell pool in cord blood

    Författare :Sofia Frändberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cord blood; Cord blood bank; Cord clamping; Hematopoietic stem cell transplantation; Hematopoietic stem and progenitor cells; CD34; Side Population; Aldehyde dehydrogenase; Apoptosis; CDCP1;

    Sammanfattning : Hematopoietic stem cell transplantation (HSCT) is a curative treatment for a wide range of malignant and hereditary disorders. It is yet the only clinically established stem cell treatment. LÄS MER

  7. 10. Non-Invasive Measures of Heart Failure

    Författare :Mikael Kanski; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart failure; diagnosis; magnetic resonance imaging; blood flow; 4D flow; pulmonary blood volume; kinetic energy;

    Sammanfattning : Heart failure is a clinical syndrome characterized by an inability of the heart to meet the metabolic demands of the body. Approximately 1-2% of the population in the western society has the diagnosis, and the 5-year mortality rate is comparable with the common cancer diagnoses. LÄS MER
