  1. 11. Studies on skin blood flow and evaporative water loss : a bioengineering approach

    Författare :Lena Nilsson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Skin blood flow (SBF), temperature, evaporative water loss (EWL) and skin conductance (SC) measured during stimulus-response experiments reveal valuable information regarding the skin's regulatory capacity. SBF and EWL play powerful roles in keeping the human body within an adequate temperature range. LÄS MER

  3. 12. Goal-directed fluid therapy during major abdominal surgery

    Författare :Hans Bahlmann; Lena Nilsson; Robert Hahn; Anna Oscarsson Tibblin; Zsolt Molnar; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background: Both hypo- and hypervolemia increase the risk for postoperative complications after major abdominal surgery. Fluid needs vary amongst patients depending on differences in preoperative dehydration, intraoperative physiology and surgical characteristics. LÄS MER

  4. 13. Electromechanical effects and optimization modalities of cardiac resynchronization therapy

    Författare :Cinzia Valzania; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cardiac resynchronization therapy; coronary blood flow; dyssynchrony; echocardiography; exercise; heart failure; hemodynamics; intracardiac electrogram; intracardiac impedance; optimization;

    Sammanfattning : Background and aims: Heart failure is a major health care problem, with high morbidity and mortality rates. In recent years, cardiac resynchronization therapy (CRT) has become an established additive treatment for patients with advanced heart failure, left ventricular (LV) dysfunction, and wide QRS complex.

  5. 14. Image-based dynamic liver testing : studies of segmental hepatic parenchymal function and biliary flow using dynamic 99Tcm-HIDA SPECT

    Författare :Eduard Jonas; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dynamic SPECT; Segmental liver function test; Primary sclerosing cholangitis; Bile flow; Bile scintigraphy;

    Sammanfattning : The aim of the study was to create a dynamic liver function test using a tomographic imaging procedure as sampling method. The liver has multiple and complex functions. It is obvious that no single test can give a comprehensive measurement of total liver function. LÄS MER

  7. 15. A study of bacterial adhesion on a single-cell level by means of force measuring optical tweezers and simulations

    Författare :Oscar Björnham; Staffan Schedin; Ove Axner; Kirstine Berg-Sörensen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; fysik; Physics; cell research; cellforskning; molecular cell biology; molekylär cellbiologi;

    Sammanfattning : The intriguing world of microbiology is nowadays accessible for detailed exploration at a single–molecular level. Optical tweezers are a novel instrument that allows for non–invasive manipulation of single cells by the sole use of laser light and operates on the nano– and micrometer scale which corresponds to the same length scale as living cells.
