DOI: 10.1007/s10877-018-0235-z
Abstract: AbstractTo determine whether a classification based on the contour of the photoplethysmography signal (PPGc) can detect changes in systolic arterial blood pressure (SAP) and vascular tone. Episodes of normotension (SAP 90–140 mmHg), hypertension (SAP > 140 mmHg) and hypotension… read more here.

DOI: 10.1016/j.jphs.2022.02.001
Abstract: Endothelial nitric oxide synthase (eNOS) is a critical regulatory enzyme that controls vascular tone via the production of nitric oxide. Although thrombin also modulates vascular tone predominantly via the activation of protease-activated receptors (PARs), the… read more here.

DOI: 10.1016/j.taap.2018.04.012
Abstract: ABSTRACT Patients with cirrhosis have reduced systemic vascular resistance and elevated circulating bile acids (BAs). Previously, we showed that secondary conjugated BAs impair vascular tone by reducing vascular smooth muscle cell (VSMC) Ca2+ influx. In… read more here.
