1. 16. Sleep disordered breathing and hemodynamic function

   Författare :Ludger Grote; Göteborgs universitet; []
   Nyckelord :sleep apnea; hypertension; blood pressure; vascular function; exercise; arousal;

   Sammanfattning : This thesis addresses the association between sleep disordered breathing (SDB) and hemodynamic function. A cross sectional study in a sleep laboratory cohort (n=1190) demonstrated a dose-response relationship between the severity of SDB, expressed as respiratory disturbance index (RDI), and office blood pressure, heart rate, and the risk of hypertension.

3. 17. Regulation of vascular function by fluid mechanical forces. Development of a new vascular experimental platform for integrative physiological and molecular biological studies of living conduit vessels

   Författare :Li-Ming Gan; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; perfusion model; endothelium; smooth muscle cells; shear stress; pressure; nitric oxide; endothelin-1; vascular endothelial growth factor; c-jun; c-fos; real-time PCR; NO probe.;

   Sammanfattning : The vascular endothelium is a multifunctional interface between blood flow and target organs and is continuously exposed to fluid mechanical forces such as shear stress, compressive, and tensile forces. Both in vivo and in vitro data indicate that biomechanical forces exert important modulating effects on key vascular functions. LÄS MER

4. 18. Experimental studies of the regulations of synthesis and release of tissue-type plasminogen activator from vascular endothelium

   Författare :Lena Selin Sjögren; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tissue-type plasminogen activator; endothelium; fluid mechanical forces; shear stress; pressure; immunohistochemistry; gene expression;

   Sammanfattning : The fibrinolytic system has several important functions and one crucial function is the prevention and removal of fibrin deposits in blood vessels. Tissue-type plasminogen activator (t-PA) plays a key role in this process, and in vitro data suggest that an acute release of t-PA is induced as a thromboprotective response whenever clotting mechanisms are initiated.

5. 19. Epidemiological Studies of Preeclampsia : Maternal & Offspring Perspectives 

   Författare :Jóhanna Gunnarsdóttir; Anna-Karin Wikström; Sven Cnattingius; Ulf Högberg; Alexander Smárason; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Placental dysfunction; blood pressure; small-for-gestational-age; fetal growth restriction; intrauterine; prenatal exposure; postnatal height gain; linear growth;

   Sammanfattning : Preeclampsia is a placental-related disorder characterized by generalized endothelial activation. Vascular predisposition is associated with the occurrence of preeclampsia and the recurrence risk is substantial. LÄS MER

7. 20. Chronic disease risk factors in a transitional country : the case of rural Indonesia

   Författare :Nawi Ng; Lars Weinehall; Hans Stenlund; Stig Wall; Ann Öhman; Mohammad Hakimi; Cairns Smith; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chronic disease; risk factor; demographic surveillance system; smoking; elevated blood pressure; overweight and obesity; population-based intervention; Epidemiology; Epidemiologi;

   Sammanfattning : Background: The epidemic of chronic diseases is largely neglected. Although a threatening burden of chronic diseases is emerging, developing public health efforts for their prevention and control is not yet a priority for trans-national and national health policy makers. LÄS MER
