  2. 1. Chronic atrial fibrillation in man. Activation, organisation and characterisation

    Author : Magnus Holm; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ECG spectral analysis; Preferential conduction; Organisation; Conduction velocity; Refractoriness; Mechanisms; Activation pattern; Chronic; Fibrillation; Human; Atrium; Open-heart surgery; Cardiovascular system; Kardiovaskulära systemet;

    Abstract : Chronic atrial fibrillation (CAF), with a prevalence progressively increasing with age, is one of the most common cardiac arrhythmias in man and associated with increased morbidity and mortality. Previous studies have shown that, in animals as well as in man, experimental atrial fibrillation is based on different types and dimensions of intra-atrial electrical re-entry. READ MORE

  4. 2. In Vivo Diffuse Reflectance Spectroscopy of Human Tissue : From Point Measurements to Imaging

    Author : Erik Häggblad; Göran Salerud; Tomas Strömberg; Maurice C. G. Maurice C. G. Aalders; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical engineering; Medicinsk teknik;

    Abstract : This thesis presents the non-invasive use of diffuse reflectance spectroscopy (DRS) to provide information about the biochemical composition of living tissue. During DRS measurements, the incident, visible light is partially absorbed by chromophores but also scattered in the tissue before being remitted. READ MORE

  5. 3. Identification and characterization of progenitor populations in the human adult heart

    Author : Joakim Sandstedt; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cardiac progenitor cells; heart; C-kit; Side Population; Stage Specific Embryonic Antigens; FACS;

    Abstract : Traditionally, the heart has been regarded as a non-regenerative organ. During the last 10 years, this notion has been challenged. By 14C measurements, it was calculated that at the age of 50, about 45% of all cardiomyocytes had formed after birth. READ MORE

  6. 4. Cell transplantation with human mesenchymal or embryonic stem cells to the heart : experimental, molecular, immunological and echocardiographic studies

    Author : Karl-Henrik Grinnemo; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Human mesenchymal stem cells; human embryonic stem cells; human cardiomyocyte; Islet-1; Nkx2.5; stem cell; xenotransplantation; rejection; FoxP3 T-cells; tolerance; CTLA4Ig; anti- CD40L; LFA-1;

    Abstract : Background: Human mesenchymal stem cells (hMSC), human embryonic stem cells (HESC) and human fetal cardiomyocyte progenitor cells (HFCP) all represent possible candidate cells for regeneration of damaged myocardium. Although they represent cell types with many positive attributes, their capacity to engraft, to differentiate into mature cardiomyocytes, to improve myocardial function and their immunological properties are the focus of these studies.

  7. 5. Embryonic and adult cardiac stem cells : molecular, electrophysical and immunological characteristics for cardiac repair

    Author : Rami Genead; Karolinska Institutet; Karolinska Institutet; []
    Keywords : human resident cardiac progenitor;

    Abstract : Background: The concept of myocardial regeneration by means of stimulating the endogenous regenerative potential in situ is an attractive approach. This offers distinct advantages to stem cell implantation where the problems with engraftment and immune rejection are avoided. READ MORE
