1. 1. On cellular sources for intimal hyperplasia after vascular interventions

   Författare :Stefan Mellander; Göteborgs universitet; []
   Nyckelord :intimal hyperplasia; vascular intervention; smooth muscle cell; blood-born mononuclear cell; prosthetic graft; balloon injury; pig; rabbit;

   Sammanfattning : Vascular interventions for the treatment of symptomatic atherosclerosis fail in up to 40 % of the cases during the first year. One important reason is the development of a narrowing process known as intimal hyperplasia (IH). The cells forming IH resemble smooth muscle cells (SMCs) from the media of the arterial wall.

3. 2. Biomarkers of vascular function and structure in young healthy adults

   Författare :Paul Pettersson-Pablo; Anita Hurtig-Wennlöf; Torbjörn Nilsson; Lars Breimer; Anders Larsson; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atherosclerosis; vascular function; vascular structure; body composition; age; inflammation; clinical chemistry; biomarker;

   Sammanfattning : Atherosclerosis is a disease affecting the blood vessels in the body. Its pathophysiologic mechanisms involve infiltration of the vessel walls by fatty matter and immune cells. This process is slow, starting in childhood but typically not manifesting as symptomatic disease until late adulthood (after 60 years of age). LÄS MER

4. 3. 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.

5. 4. Diesel exhaust and wood smoke : mechanisms, inflammation and intervention

   Författare :Ala Muala; Thomas Sandström; Mark W Frampton; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Air pollution; deposition; bronchoscopy; Immunohistochemstry; filter; NO bioavailability; lungmedicin; Lung Medicine;

   Sammanfattning : Background Particulate matter (PM) air pollution is associated with increased respiratory and cardiovascular morbidity and mortality. Diesel engine exhaust (DE) and wood combustion are major contributors to ambient air pollution and adverse health effects. LÄS MER

7. 5. Level Set Segmentation and Volume Visualization of Vascular Trees

   Författare :Gunnar Läthén; Reiner Lenz; Magnus Borga; Lasse Riis Østergaard; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; level set methods; image segmentation; edge detection; visualization; volume rendering; blood vessels; angiography; vascular trees;

   Sammanfattning : Medical imaging is an important part of the clinical workflow. With the increasing amount and complexity of image data comes the need for automatic (or semi-automatic) analysis methods which aid the physician in the exploration of the data. LÄS MER
