13. Arterial vascularization of the sinoatrial node area in normal human hearts / Vascularização arterial da região do nó sinoatrial em corações humanos normais
The sinoatrial node (NSA) is responsible for the production of the nervous impulses, which determine the cardiac contraction and its blood supply is provided by the sinoatrial node artery - ANSA. In this research we aimed to study the arterial vascularization of the NSA area in normal human hearts, with macroscopic techniques intending to identify the origin

14. Anatomical comparison of the anterolateral thigh perforator flap and the parascapular and lateral arm skin flaps / "Comparação anatômica entre o retalho perfurante ântero-lateral da coxa e os retalhos cutâneos paraescapular e lateral do braço"
The description of the skin flaps based on perforator vessels is recent. The vascularization of the anterolateral thigh flap is based on perforator vessels coming from the lateral circumflex femoral artery. It has a thin skin paddle, a long and large vascular pedicle and low donor site morbidity. However, the dissection of the intramuscular path of its pedic

15. A subplacenta da paca (Agouti paca, Linnaeus 1766) / The subplacenta of the paca (Agouti paca, Linnaeus 1766)
The rodents of suborder hystricomorph, in which is classified the Agouti paca, present hemochorial type placentation and develops an unique structure known as subplacenta. In spite of many report of its presence in several species, the possible functions of this structure related to placenta and pregnancy remains speculative, mainly due to the diversity of f

16. Arterial vascularization of the papilares muscles of the left ventricle of the dog´s heart (Canis familiaris - L. 1758) / Vascularização arterial dos músculos papilares do ventrículo esquerdo de cães (Canis familiaris - L. 1758)
Cardiac irrigation, both in man and in other mammals, is a relevant subject that has been researched by several authors, among whom H. Rodrigues and his team, who have been seeking to subsidy the biomorphological base for myocardium vascular diseases. Information about the arterial vases related to papillary muscles is incomplete and scarce in the medical li

17. Prognosis of pituitary adenomas with arteriographic abnormal vascularization
A case report and five additional cases from the literature of angiographically demonstrated abnormal vascularization of chromophobe adenomas are presented. The appearance is that of a fine network of vessels appearing in the arterial phase and a homogeneous blush beginning in the capillary phase and lasting throughout the venous phase. The network is derive

18. Angiogenin activates endothelial cell phospholipase C.
Low concentrations of angiogenin activate the inositol-specific phospholipase C of cultured pulmonary artery, umbilical vein, and capillary endothelial cells, promoting a transient increase in the intracellular levels of 1,2-diacylglycerol and inositol trisphosphate. The response is strongly dose dependent with a maximum in the ng/ml concentration range and,
