  1. 6. Studies on pericytes in health and disease

    Författare :Maya Hestnes Nisancioglu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Pericytes are the perivascular mural cells of microvessels. They are intimately associated with endothelial cells and communicate with them via direct physical contact or through paracrine signaling pathways. These interactions are important for blood vessel maturation, remodeling, and maintenance. LÄS MER

  3. 7. Cardiac and vascular pathology in Lewy body disease and Alzheimer's disease: exploring neurocognitive disorder beyond the brain

    Författare :Keivan Javanshiri; Lund Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The first aim of this thesis was to evaluate the prevalence of cardiovascular disease (CaVD), hypertension (HT), and type 2 diabetes mellitus (T2DM) in the neurodegenerative disorders Alzheimer’s disease (AD) and Lewy body disease (LBD). These conditions are considered modifiable risk factors for vascular dementia (VaD), and recent research has proposed its association with AD. LÄS MER

  4. 8. Global sequence and dispersion of ventricular repolarization: In vivo validation of non-invasive parameters using monophasic action potential mapping technique

    Författare :Yunlong Xia; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; dispersion; electroanatomical mapping; T wave; epicardial pacing; Ventricular repolarization; monophasic action potential;

    Sammanfattning : The purposes are to validate the noninvasive parameters, QT interval, QT dispersion, Tpeak-Tend interval, and the activation recovery time (ART) for estimation of global dispersion of ventricular repolarization (DVR), and to investigate the changes of repolarization sequence and DVR by altered ventricular pacing sites. The material consisted of 12 patients (Study I) and two series healthy pigs with 10 in each (Studies II and III; Studies IV and V). LÄS MER
