13. Aspectos morfológicos da placenta e anexos fetais da paca (Agouti paca, Linnaeus 1766) / Morphological aspects of the placenta and fetal annexes of Paca (Agouti paca, L.,1766)
Neste trabalho realizamos a análise macroscópica das estruturas do funículo umbilical e da placenta, a análise macroscópica da vascularização funicular e placentária, e a análise à microscopia de luz dos componentes funiculares da paca, procurando melhor conhecer a morfologia reprodutiva desta espécie. Para tanto, utilizamos nove pacas fêmeas, pr

14. Enhanced coronary vasa vasorum neovascularization in experimental hypercholesterolemia.
Coronary arteries contain a network of vasa vasorum in the adventitia. The three-dimensional anatomy of the vasa vasorum in early coronary atherosclerosis is unknown. This study was designed to visualize and quantitate the three-dimensional spatial pattern of vasa vasorum in normal and experimental hypercholesterolemic porcine coronary arteries, using a nove

15. Effects of aortic pressure and vasoactive agents on the vascular resistance of the vasa vasorum in canine isolated thoracic aorta.
1. We have developed a new preparation for continuously measuring changes in vascular resistance of the vasa vasorum of the canine isolated thoracic aorta perfused at a constant flow rate with Krebs-bicarbonate solution. 2. An increase of more than 150 mmHg in aortic pressure caused a significant increase in the vascular resistance of the vasa vasorum. 3. 5-

16. Arterial vasa vasorum: a quantitative study in the rat.
This study was designed to quantitate the vasa vasorum of common iliac arteries in 20 rats. The number of vasa vasorum per mm2 of arterial wall was extremely variable - from 0 to 124, the mean being 33 . 95 +/- 29 . 86 (S.D.). There was no significant difference in the vasa vasorum vascularity between the right and left common iliac arteries. The mean wall t

17. Regulation of Blood Flow to the Aortic Media in Dogs
Morphologic observations suggest that the inner layers of the thoracic aorta in man and dog are avascular and the outer layers have vasa vasorum. It appears that vasa vasorum are essential in the thoracic aorta because their interruption produces medial necrosis. These experiments provide the first measurements of blood flow through aortic vasa vasorum and e

18. PI3K, Rho, and ROCK play a key role in hypoxia-induced ATP release and ATP-stimulated angiogenic responses in pulmonary artery vasa vasorum endothelial cells
We recently reported that vasa vasorum expansion occurs in the pulmonary artery (PA) adventitia of chronically hypoxic animals and that extracellular ATP is a pro-angiogenic factor for isolated vasa vasorum endothelial cells (VVEC). However, the sources of extracellular ATP in the PA vascular wall, as well as the molecular mechanisms underlying its release,
