  1. 16. Advancements in DSC and BOLD perfusion imaging: Acquisition, analysis and clinical application

    Författare :Jonathan Arvidsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic Resonance Imaging; Cerebral Blood Flow; Cerebral Blood Volume; Time To Peak; Biophysical modelling; Signal representation; MRI;

    Sammanfattning : This thesis is focused on perfusion MRI techniques and topics related to image acquisition, analysis and clinical applications. The first half of the thesis is focused on dynamic susceptibility contrast (DSC) MRI, a technique which is based on the contrast enhancements caused by an intravenously administered paramagnetic contrast agent.

  3. 17. Effects of Dehydration and Blockade of the Renin-Angiotensin System in the One-humped Camel (Camelus dromedarius)

    Författare :Mahmoud Al Haj; Fred Nyberg; Santi Spampinato; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood; biochemical analysis; catecholamine; colorimetric assay; cortisol; dehydration; dromedary camel; glutathione; hematological analysis; HPLC; insulin- like growth factor-1; losartan; plasma; receptors; radioimmunoassay; serum; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : The one-humped or the dromedarian camel is a pseudo-ruminant mammal, well adapted to the hot and dry climates of the desert. Its ability to withstand torrid heat and extreme desiccation is of paramount importance to its survival. LÄS MER

  5. 19. Measurement and Analysis of Intracardiac Blood Flow and Vortex Ring Formation

    Författare :Johannes Töger; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood flow; dynamical systems; magnetic resonance imaging; heart failure; vortex ring formation;

    Sammanfattning : Increased understanding of the pumping mechanics of the heart are of great importance to develop diagnostics, treatment and prognostics for cardiovascular diseases. Blood flow in the heart is connected to its anatomy and function, and may therefore be a sensitive marker of cardiac health and disease. LÄS MER

  7. 20. Blood pressure, renal functional and structural changes, in normal and preeclamptic pregnancy

    Författare :Helena Strevens; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics; renal biopsy; renal function; pregnancy; preeclampsia; physiology; parity; endotheliosis; cystatin C; Blood pressure; BMI; gynaecology; andrology; reproduction; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet;

    Sammanfattning : The kidneys play a pivotal role in the adaptive physiology of the pregnant woman, presenting some changes at term similar to the changes found in preeclampsia – a state of increased risk of fetal and maternal morbidity and mortality. The aim of these investigations was to explore possible similarities in blood pressure regulation, renal function and structure in normal term and preeclamptic pregnancy, to ascertain whether both conditions in fact are different degrees of an adaptive process in reaction to pregnancy.
