A hidden structural vulnerability in the thrombospondin-2 deficient aorta increases the propensity to intramural delamination Mice lacking thrombospondin-2 (TSP2) represent an animal model of impaired collagen fibrillogenesis. Collagen constitutes ~1/3 of the wall of the normal mu... C Bellini,NJ ...
In vertebrates the notochord is mostly replaced by the vertebral column, and we refer to the big nerve cord as the spinal cord and to the big artery as the aorta. The vertebral column doesn’t just give the body stiffness and flexibility and something to hang muscles on, it also has a ...
Preincubation with 20 pmol/liter amylin impaired the relaxant responses induced by acetylcholine in rat aorta and mesenteric microvessels. This effect was abolished in both vascular beds in the presence of 100 micromol/liter NG-nitro-L-arginine methyl ester.We propose that amylin levels and ...
Methods and devices for placing a conduit in fluid communication with a target vessel and a source of blood, such as the aorta or a heart chamber. The device may be actuated using one hand to place the conduit. The invention allows air i... DC Gittings,AR Rapacki,A Sharkawy,... - ...
The rope model of the heart (Figure 12) shows the beginning and the end of the myocardial band at the aorta and pulmonary artery (right), the circumferential wrap of the basal loop (center) and the helix with basic line a half-angle m = (left). This halfangle is directly related ...

As expected, the spline based model improves the fitting accuracy of the elliptic one and specially in complex aorta cross-sections. However, we have observed that with a high number of knots some cross sections may show high error values due to the adaption of the function to noise....

Methods and systems for processing medical diagnostic images for review, e.g., by a physician or radiologist, are provided. Methods and systems herein can automatically detect the vertical section of the ascending and descending aorta in which medical images, such as axial CT images, give an ...
