  1. 6. Left atrial function in health and disease

    Författare :Mark Henein; Per Lindqvist; Stellan Mörner; Reidar Winter; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left atrium; Doppler echocardiography; atrial interaction; atrial pressure;

    Sammanfattning : The Objectives of this thesis are:1) To study possible atrial interaction in patients with right and left ventricular outflow tract obstruction due to significant pulmonary (PS) and aortic valve stenosis (AS), respectively.2) To assess left atrial (LA) intrinsic myocardial function and its relationship to indirect measures of left ventricular (LV) filling pressures in patients with paroxysmal atrial fibrillation (PAF).

  3. 7. Death, survival, and morphological development of hippocampal granule cells born in an inflammatory environment

    Författare :Sara Bonde; Lund Neurologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microglia; hippocampus; Adult neurogenesis; gephyrin; dendritic spines;

    Sammanfattning : The brain continues to form new neurons throughout life. This process of adult neurogenesis has been thoroughly documented in several species including birds, rodents and humans. LÄS MER

  4. 8. tPA mediated activation of PDGF-C/PDGFRα signaling in the CNS

    Författare :Christina Stefanitsch; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The platelet derived growth factors (PDGFs) and their tyrosine kinase receptors play an essential role during development, in adult tissue homeostasis and in several pathological events. PDGF-CC, a ligand for PDGFRα, is secreted as an inactive dimer. LÄS MER

  5. 9. Fluid dynamic principles for analysis of intracranial pressure control : application towards space medicine and hydrocephalus

    Författare :Petter Holmlund; Anders Eklund; Sara Qvarlander; Jan Malm; Marek Czosnyka; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intracranial pressure; posture; cerebrospinal fluid; microgravity; venous collapse; internal jugular vein; fluid dynamics; venous pressure; spaceflight-associated neuro-ocular syndrome; hydrocephalus; mathematical modeling; ultrasound; magnetic resonance imaging;

    Sammanfattning : Intracranial pressure (ICP) is an important component of the fluid dynamic environment of the brain and plays a central role with regards to the maintenance of normal cerebral blood flow and neuronal function. However, many regulatory mechanisms controlling the ICP are still poorly understood. LÄS MER

  7. 10. Amyloid precursor protein : cellular studies and animal models

    Författare :Tatjana Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterised by a number of neuropathological features, including extracellular deposits composed primarily of amyloid-β (Aβ) peptides. Aβ is derived from proteolysis of the amyloid precursor protein (APP) by consecutive action of β and γ-secretases. LÄS MER
