Indoleamine 2,3-dioxygenase (IDO) metabolizes L-tryptophan to L-kynurenine, promotes immunosuppression, and has been described as a consumer of superoxide. We discovered IDO expression in periaortic fat and tested the hypothesis that periarterial IDO functionally reduces agonist-induced contraction. Our model was the thoracic aorta, abdominal aorta, and superior mesenteric artery of the male Sp...

background: in this study, we used a new computerized analytical method for the measurement of the endothelial function in sequential ultrasound images and compared it with histological studies, using the abdominal aorta in normal and atherosclerotic rabbits. methods: six rabbits received a standard rabbit chow as the normal group and the other 6 rabbits were fed a high cholesterol diet for fou...

Mainly four 1) prevalence of the pathology 2) the accuracy and the invasivity of the test used for the screening 3) the effectiveness of the necessary interventions to correct the pathology and the relative cost 4) the general economic commitment. Screening for abdominal aorta aneurysm corresponds to these criteria. The prevalence is elevated if the screening is turned to a selected population:...

OBJECTIVE The surgical treatment of recurrent coarctation in adults supposes a redo left thoracotomy with adhesions and high risk of bleeding and injury of adjacent nerves. The rate of paraplegia in these cases may reach 2.6%. Extra-anatomic aortic bypass avoids these complications. We present our results with ascending-to-abdominal aorta extra-anatomic bypass for recurrent aortic coarctation i...
