Biventricular structural and functional responses to aortic constriction in a rabbit model of chronic right ventricular pressure overload
(MOSBY-ELSEVIERNEW YORK, 2012)
Objectives: Chronic right ventricular (RV) pressure overload results in pathologic RV hypertrophy and diminished RV function. Although aortic constriction has been shown to improve systolic function in acute RV failure, ...

A mathematical model for wave propagation in elastic tubes with inhomogeneities: Application to blood waves propagation
(Elsevier B.V., 2007-12-15)
We study the propagation of waves in an elastic tube filled with an inviscid fluid. We consider the case of inhomogeneity whose mechanical and geometrical properties vary in space. We deduce a system of equations of the ...
End-systolic pressure-diameter relation of the left ventricle during transient and sustained elevations of blood pressure
(Sociedade Brasileira de Cardiologia (SBC), 2000-07-01)
OBJECTIVE: To assess the effect of transient and sustained variations in cardiac load on the values of the end-systolic pressure-diameter relation (ESPDR) of the left ventricle. METHODS: We studied 13 dogs under general ...

Role of distal cerebral vasculature in vessel constriction after aneurysm treatment with flow diverter stents
(BMJ, 2020-08)
Background Treatment of intracranial aneurysms with flow diverter stent (FDS) procedures can lead to caliber changes of jailed vessels. The reason some branches remain unchanged and others are affected by narrowing remains ...

Cholinergic regulation along the pulmonary arterial tree of the South American rattlesnake: vascular reactivity, muscarinic receptors, and vagal innervation
(Amer Physiological Soc, 2020-08-01)
Vascular tone in the reptil-ian pulmonary vasculature is primarily under cholinergic, muscarinic control exerted via the vagus nerve. This control has been ascribed to a sphincter located at the arterial outflow, but we ...
The role of potassium channels in the vasodilatory effect of caffeine in human internal mammary arteries
There is little information about the direct effect of caffeine in human blood vessels. The purpose of this study was to evaluate the direct vascular effect of caffeine on human internal mammary artery (IMA) and the ...
Endothelin-1 Induces Contraction of Female Rat Internal Pudendal and Clitoral Arteries through ET(A) Receptor and Rho-Kinase Activation
(WILEY-BLACKWELL, 2010)
Introduction. Endothelin-1 (ET-1), a potent vasoconstrictor peptide, acts mainly through the Gprotein-coupled ET(A) receptor (ET(A)R). Increased vascular ET-1 production and constrictor sensitivity have been observed in ...
