  1. 16. Vascular Dysfunction in Stroke and CADASIL

    Författare :Anna Stenborg; Lars Lind; Andreas Terent; Toste Länne; Uppsala universitet; []
    Nyckelord :Internal medicine; stroke; CADASIL; endothelium; vasodilation; Invärtesmedicin;

    Sammanfattning : Cerebrovascular disease (CVD) is strongly linked to hypertension and generally occurs later in life than coronary artery disease (CAD). Three quarters of the patients with symptomatic CVD are above 65 years of age. The risk factors are the same for CVD and CAD, but the relative importance of the vascular risk factors differs greatly.

    Sammanfattning : Effects of Oestrogen on Haemodynamic and Vascular Reactivity A study in animal models and humans Lisa Brandin Institute of Medicine, Department of Emergency and Cardiovascular Medicine, Sahlgrenska University Hospital/Östra, Sahlgrenska Academy, Göteborg University, Göteborg, Sweden ABSTRACT Previous studies have shown that oestrogen, the female sex hormone, plays a protective role in the cardiovascular system. However the site of action remains incompletely understood. LÄS MER

  4. 18. Insulin resistance and IGF-I sensitivity in vascular cells - impact of hybrid receptors : With special regard to diabetes

    Författare :Git Johansson; Hans Arnqvist; Pierre De Meyts; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Diabetic complications largely affect the circulation and are associated with resistance to insulin and altered levels of insulin-like growth factor-I (IGF-I). Insulin resistance and altered IGF-I levels are also associated with vascular disease. LÄS MER

  5. 19. Endothelin-1 in the regulation of vascular function and glucose metabolism in insulin resistance

    Författare :Alexey Shemyakin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Insulin resistance plays a major role in the pathogenesis of type 2 diabetes and is an important risk factor for cardiovascular disease. Endothelial dysfunction, characterized by reduced bioactivity of nitric oxide and increased activity of the vasoconstrictor and pro-inflammatory peptide endothelin-1 (ET-1), is present in insulin-resistant states and is an important factor promoting the development of cardiovascular complications in patients with insulin resistance.

  7. 20. Vascular density and bone marrow fibrosis in childhood acute lymphoblastic leukemia

    Författare :Ulrika Norén Nyström; Anders Bergh; Erik Forestier; Göran Roos; Henrik Schrøder; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Childhood acute lymphoblastic leukemia; microvessel density; bone marrow fibrosis; in vitro drug resistance; minimal residual disease; outcome; Oncology; Onkologi;

    Sammanfattning : Background: In childhood acute lymphoblastic leukemia (ALL), the cure rate has now reached 80% in the western world. Even so, 15¬–20% will die from the disease or treatment-related causes, among them children who did not present any known unfavorable features at diagnosis. LÄS MER
