Intracranial baroreflex is attenuated in an ovine model of renovascular hypertension

Scientific Reports, 2021
We have previously shown that elevations in intracranial pressure (ICP) within physiological ranges in normotensive animals increase arterial pressure; termed the intracranial baroreflex.

Arterial smooth muscle cell PKD2 (TRPP1) channels regulate systemic blood pressure

eLife, 2018
Systemic blood pressure is determined, in part, by arterial smooth muscle cells (myocytes). Several Transient Receptor Potential (TRP) channels are proposed to be expressed in arterial myocytes, but it is unclear if these proteins control physiological ...

LES of non-Newtonian physiological blood flow in a model of arterial stenosis [PDF]

, 2012
Large Eddy Simulation (LES) is performed to study the physiological pulsatile transition-to-turbulent non-Newtonian blood flow through a 3D model of arterial stenosis by using five different blood viscosity models: (i) Power-law, (ii) Carreau, (iii ...

Liberating carotid arteries: measuring arterial pressure through femoral artery in mice

Clinical and Experimental Hypertension, 2019
Researches involving arterial pressure measurements in mice have primarily relied on carotid arterial catheterization. However, in some circumstances, measuring arterial pressure through the carotid arterial impairs accuracy.
