  1. 1. Closing the gap : applying health and socio-demographic surveillance to complex health transitions in South and sub-Saharan Africa

    Författare :Stephen M Tollman; Stig Wall; Demissie Habte; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; demographic surveillance system; health transition; mortality transition; fertility transition; health policy; primary health care; South Africa; Epidemiology; Epidemiologi;

    Sammanfattning : Background: The challenge of research in resource-poor settings remains a profound concern and is closely linked to African social development. Work of this thesis spans the end of apartheid and first decade of the democratic era in South Africa, along with emergence of the HIV/AIDS pandemic. LÄS MER

  3. 2. Regulation of aortic wall mechanics and stress : An experimental study in man

    Författare :Håkan Åstrand; Toste Länne; Matts Karlsson; Martin Björck; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aorta; wall stress; remodeling; IMT; gender; diabetes mellitus; aging; collagen; elastin; Vascular surgery; Kärlkirurgi;

    Sammanfattning : The abdominal aorta (AA) in man is a vulnerable artery prone to atherosclerosis as well as aneurysmatic dilation. The underlying aortic composition, mechanical properties as well as the mechanisms responsible for age-related changes and vascular disease are however largely unknown. LÄS MER

  4. 3. Vessel wall integrity : influence of genetics and flow

    Författare :Hanna Björck; Toste Länne; Per Eriksson; Sverker Jern; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Cardiovascular disease (CVD) is the major cause of death worldwide. Underlying causes, such as atherosclerosis and hypertension, are associated with remodeling of the vessel wall ultimately leading to loss of structural integrity. There are a number of factors that can influence vascular remodeling and hence structural integrity. LÄS MER

  5. 4. Mechanosensing in the vascular wall - the role of cellular microdomains in vascular remodeling

    Författare :Sebastian Albinsson; Kärlfysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur; cytochemistry; histochemistry; wall stress; shear stress; hypertension; Histology; differentiation; growth; caveolin; smooth muscle; actin; Fysiologi; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : The vascular wall has a remarkable capacity to adapt to mechanical forces exerted by the intraluminal blood pressure and flow. This includes rapid change in contractile tone as well as chronic alteration of vessel structure if the stimulus persists. Stretch of the intact blood vessel wall promotes growth and contractile differentiation. LÄS MER

  7. 5. Lymphatic Vascular Morphogenesis : From Progenitors to Functional Vessels

    Författare :Nina Daubel; Taija Mäkinen; Markus Affolter; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lymphatic vasculature; morphogenesis; lymphvasculogenesis; mesentery; lymphatic capillary;

    Sammanfattning : The lymphatic vasculature is an important part of the circulatory system and crucial for normal functioning and maintenance of tissues. Yet, our understanding of the processes underlying lymphatic development and homeostasis are surprisingly limited. LÄS MER
