recommendations! Published in 2018 at "JAMA Neurology"

DOI: 10.1001/jamaneurol.2018.1321

Abstract: Importance White matter hyperintense lesions (WMHs) are highly prevalent in patients with reversible cerebral vasoconstriction syndrome (RCVS); however, their characteristics and underlying pathophysiology are unclear. Objective To investigate the spatiotemporal distribution and pathomechanisms of WMHs… read more here.

recommendations! Published in 2020 at "Current Pain and Headache Reports"

DOI: 10.1007/s11916-020-00908-1

Abstract: Reversible cerebral vasoconstriction syndrome (RCVS) is a disorder with distinct features: recurrent thunderclap headaches with reversible vasoconstriction of intracranial arteries. Substantial studies regarding outcomes after RCVS were conducted, showing favorable functional outcomes in most patients… read more here.

recommendations! Published in 2019 at "Current opinion in pharmacology"

DOI: 10.1016/j.coph.2019.04.002

Abstract: The sympathetic nervous system exerts a vasoconstrictor influence over peripheral vascular beds that is counter-regulated by local vascular signaling mechanisms (i.e. sympathetic escape, sympatholysis, and myoendothelial feedback). The endothelium has emerged as a primary site… read more here.

recommendations! Published in 2019 at "European Journal of Pharmacology"

DOI: 10.1016/j.ejphar.2019.01.007

Abstract: &NA; Subarachnoid hemorrhage (SAH) is associated with increased cerebral artery sensitivity to vasoconstrictors and release of the perivascular sensory vasodilator CGRP. In the current study the constrictive phenotype and the vasodilatory effects of exogenous and… read more here.

DOI: 10.1016/j.mvr.2022.104363

Abstract: OBJECTIVE Reproducibility of the reflex cutaneous vasoconstriction response is currently unknown. Our aim was to determine the test-retest reproducibility of laser speckle contrast imaging (LSCI) and varying sampling depths of laser Doppler flowmetry (LDF) in… read more here.

DOI: 10.1016/j.phytol.2019.04.015

Abstract: Exaggerated vasoconstriction plays a critical role in the development of hypertension in metabolic syndrome (MetS). A crude methanolic extract of Euryops arabicus (EA) was found to alleviate MetS-associated exaggerated vasoconstriction. The methanolic extract of EA… 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.
