1. 1. Platelet Activation and Inhibition in Connection with Vascular Stents

   Författare :Kjeld Christensen; Rolf Larsson; Sten Husted; Uppsala universitet; []
   Nyckelord :Medicine; platelets; inhibition; activation; stents; ACS; Medicin;

   Sammanfattning : This thesis describes the Chandler loop, which makes it possible to conduct studies in vitro of molecular and cellular interactions between whole blood and stents. It was possible to monitor activation and inhibition of the cascades systems, leukocytes and platelets by combining different platelet inhibitors and heparin coating of stents. LÄS MER

4. 3. Carcinoma of the Urinary Bladder. Aspects of treatment, Costs and Follow-up Routines

   Författare :Ingela Berrum-Svennung; Göteborgs universitet; []
   Nyckelord :bladder cancer; cystectomy; stents; economics; follow-up cystoscopy; single-instillation; epirubicin; recurrence size;

   Sammanfattning : Aims: To determine costs and factors related to the total costs of cystectomy. To study the results of the radiological examinations performed 7-14 days after a cystectomy. To investigate if a single instillation of epirubicin after transurethral resection (TUR) may influence the time to the first recurrence and its size. LÄS MER

5. 4. Aspects on Imaging and Endovascular Treatment of Aortic Dissection and Aneurysm

   Författare :Mats-Ola Eriksson; Rickard Nyman; Anders Wanhainen; Johnny Steuer; Mårten Falkenberg; Uppsala universitet; []
   Nyckelord :Aneurysms; aorta; stents; ultrasound; colour Doppler; vascular; interventional; aortic dissection; complicated; TEVAR; EVAR; re-intervention; survival; thrombosis; false lumen; aortic remodelling; Radiology; Radiologi;

   Sammanfattning : Aortic aneurysm and dissections are potentially life threatening conditions. The advent of endovascular aortic repair (EVAR) and thoracic endovascular aortic repair (TEVAR) has reduced perioperative mortality and morbidity and are now established therapy methods for treatment of aortic disease.

7. 5. Use of EBSD Technique as a Means to Investigate the Microstructure of Engineering Materials

   Författare :Muhammad Umar Farooq; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser cladding; coronary stents.; strain induced phase transformation; EBSD; oligocrystalline structures; WC-Co;

   Sammanfattning : AbstractMaterials Science and Engineering has the aim to design or engineer the structure of a material to produce a predetermined set of properties. To be able to understand and predict the properties and observable characteristics of engineering materials, it is therefore necessary to understand their microstructure. LÄS MER
