1. 11. Non-invasive measurement of skeletal muscle blood flow using by photoplethysmography. Experimental studies on the human leg

   Författare :Qiuxia Zhang; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; photoplethysmography; skeletal muscle blood flow; perfusion pressure; intramuscular pressure; venous obstruction; muscle exercise; non-invasive; limb elevation; vibration exposure; hyperaemia; foot pump.;

   Sammanfattning : The purpose of this thesis was to validate a new non-invasive photoplethysmography (PPG) method for measuring relative changes in local muscle blood flow (MBF) in the human leg. Experimental conditions expected to impede or increase local MBF were used to test responsiveness of the PPG. LÄS MER

3. 12. Risk factors for cardiovascular events and incident hospital-treated diabetes in the population

   Författare :Payam Khalili; Peter Nilsson; Johan Jendle; Annika Rosengren; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adiponectin; blood pressure; cardiovascular risk; diabetes; inflammation; pulse pressure; sialic acid; smoking; Medicin; Medicine;

   Sammanfattning : Background: Cardiovascular disease (CVD) is the leading cause of death worldwide. Well-established risk factors for CVD include increasing age, male sex, sedentary lifestyle, obesity, smoking, diabetes, hypertension, dyslipidaemia and low socio-economic status. Traditional risk factors do, however, not fully explain cardiovascular risk in general. LÄS MER

4. 13. 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

5. 14. Bimetallic palladium catalysts for catalytic combustion of methane

   Författare :Katarina Persson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; catalytic combustion; gas turbine; methane; palladium; bimetal; morphology; TPO; TEM; EDS; methane activity; stability; pressure; Kemiteknik; Chemical engineering; Kemiteknik;

   Sammanfattning : Catalytic combustion is a promising combustion technique in gas turbines, which results in ultra low levels of NOx, CO and unburned hydrocarbons. Due to the low combustion temperature achieved in catalytic combustion almost no thermal NOx is formed. The focus in this thesis will be on the first stage in a catalytic combustion chamber, i.e. LÄS MER

7. 15. Lateral epicondylitis : intramuscular blood flow, pressure and metabolism in the ECRB muscle

   Författare :Eva Oskarsson; Karin Piehl Aulin; Eva Nylander; Örebro universitet; []
   Nyckelord :Lateral epicondylitis; ECRB; intramuscular microcirculation; intramuscular pressure; botulinum toxin; muscle metabolism; pain; MEDICINE; MEDICIN; Idrottsvetenskap; Sports Science;

   Sammanfattning : Lateral epicondylitis is classified as an overuse injury and the main symptom is pain from the lateral side of the elbow. There is general agreement that the extensor carpi radialis brevis (ECRB) muscle and its proximal tendon play a central role in the development of lateral epicondylitis. However, the pathophysiology is to a large extent unclear. LÄS MER
