2. 16. Assessment of predicting blood flow and atherosclerosis in the aorta and renal arteries

   Author : Alexander Fuchs; Lisa Prahl Wittberg; Örjan Smedby; Chunliang Wang; Anders Persson; Elazer Edelman; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blodflödessimulering; Åderförkalkning; Väggskjuvspänning; Blodrehologiska modeller; Engineering Mechanics; Teknisk mekanik;

   Abstract : Cardiovascular diseases (CVD) are the most common cause of death in large parts of the world. Atherosclerosis (AS) has a major part in most CVDs. AS is a slowly developingdisease which is dependent on multiple factors such as genetics and life style (food, smoking, and physical activities). READ MORE

4. 17. Aspects on the influence of the thoracic wall on the pathogenesis of idiopathic scoliosis

   Author : Bo Sevastik; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Experimental and clinical studies were performed in order to study the possible influence of the thoracic wall on the pathomechanism of adolescent idiopathic scoliosis, IS. Experimental longitudinal elongation of one rib resulted in a deviation of the vertebra in the frontal plane to the contralateral side of the elongated rib, an anterior displacement in the sagittal plane and a rotation towards the convexity of the curve, thus a deviation identical to the 3-D configuration of the spine seen in IS.

5. 18. Chlamydophila pneumoniae in Cardiovascular Diseases : Clinical and Experimental Studies

   Author : Marie Edvinsson; Göran Friman; Eva Hjelm; Nils-Gunnar Ilbäck; Christina Nyström-Rosander; Stefan Thelin; Björn Berdal; Uppsala universitet; []
   Keywords : Communicable diseases; Chlamydophila pneumoniae; Chlamydia pneumoniae; trace elements; atherosclerosis; aortic valve stenosis; thoracic aortic aneurysm; aortic dissection; hepcidin; iron; Infektionssjukdomar;

   Abstract : Chlamydophila pneumoniae (C. pneumoniae) has been suggested as a stimulator of chronic inflammation in atherosclerosis. C. pneumoniae DNA was demonstrated in aortic biopsies in 50% of patients with stable angina pectoris or acute coronary syndrome undergoing coronary artery bypass grafting. READ MORE

6. 19. Hemodynamic and cardiometabolic studies in patients with distributive circulatory dysfunctions : with special reference to the effects of the beta-1-adrenoreceptor agonist prenalterol

   Author : Sebastian Reiz; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aortic aneurysm surgery; gram negative septic shock; hemodynamics; myocardial metabolism; thermodilution; thoracic epidural block; volume loading; prenalterol;

   Abstract : A total of 49 patients were studied, using invasive hemodynamic techniques with systemic arterial, pulmonary artery and right atrial pressure recordings together with thermodilution cardiac output determinations. Sixteen of the patients were also subjected to cardiometabolic studies, using measurement of coronary sinus blood flow by the continuous thermodilution technique and analyses of oxygen content and lactate concentration in the systemic and coronary circulation.

7. 20. Cerebrovascular accidents associated with aortic manipulation during cardiac surgery

   Author : Patrik Boivie; Gunnar Engström; Magnus Hansson; Henrik Ahn; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; aortic atherosclerosis; aortic cannulation; aortic cross-clamp; cardiac surgery; cerebral protection; cerebrovascular accidents; epiaortic ultrasound; intra-aortic filter; Kirurgi; Surgery; Kirurgi; Thoracic and Cardivascular Suregery; kirurgi; särskilt thoraxkirurgi;

   Abstract : Background: Despite the successful development in cardiac surgery, cerebrovascular accidents (CVA) remain a devastating complication. Aortic atherosclerosis has been identified as a major risk factor for CVA. READ MORE
