Abstract: We consider the flow of blood, treated as an incompressible Newtonian fluid, through vessels undergoing periodic oscillations. As remarked by many authors, in the absence of valves oscillations hinder the flow because of the lumen… read more here.

Abstract: Accumulating evidence demonstrates that microcirculation plays a role in the pathogenesis of hypertension. In the current study, we demonstrated that pancreatic islet microvascular vasomotion of spontaneously hypertensive rats (SHRs) lost the ability to regulate blood… read more here.

DOI: 10.1038/s41598-018-36970-4
Abstract: Arterioles in the cutaneous microcirculation frequently display an oscillatory phenomenon defined vasomotion, consistent with periodic diameter variations in the micro-vessels associated with particular physiological or abnormal conditions. The cellular mechanisms underlying vasomotion and its physiological… read more here.

DOI: 10.1093/ehjci/ehaa946.2450
Abstract: It is widely known that even new-generation drug-eluting stent (DES) induce coronary vasomotion abnormality. On the other hand, recent studies reported that drug-coated balloon (DCB) for native coronary artery was non-inferior to DES in medium… read more here.

DOI: 10.3389/fbioe.2022.819716
Abstract: Vasomotion is the spontaneous time-dependent contraction and relaxation of micro arteries and the oscillating frequency is about 0.01–0.1 Hz. The physiological mechanism of vasomotion has not been thoroughly understood. From the dynamics point of view,… read more here.

DOI: 10.3389/fphys.2017.00160
Abstract: We describe application of spectral analysis of laser Doppler flowmetry (LDF) signals to investigation of cerebrovascular haemodynamics in patients with post-acute ischemic stroke (AIS) and cerebrovascular insufficiency. LDF was performed from 3 to 7 days… read more here.
