Forward and backward aortic components and reflection indexes in children and adolescents: Determinants and role in high pressure states
(Bentham Science Publishers, 2018-04)
Background: High blood pressure states (HBP) would differ in wave components and reflections indexes, which could associate clinical and prognostic implications. The study aims: 1) to characterize the association of aortic ...
Design of reflectivity-based surface plasmon resonance optical sensors for ultrasound detection
(Taylor & Francis Ltd, 2021-06)
Sensors based on surface plasmon resonance present attractive features for the detection of narrow acoustic pulses since they can behave as quasi-point detectors. In order to detect fast ultrasound pressure waves, the ...
Center-to-periphery arterial stiffness gradient is attenuated and/or reversed in pregnancy-associated hypertension
(Frontiers Media, 2021-12)
Background: Non-pregnant (NP) women have a progressive increase in arterial stiffness from central-to-peripheral arteries [“stiffness gradient” (SG)], which is of physiologic importance since excessive pulsatility is ...
Analysis of aortic pressure fields from 4D flow MRI in healthy volunteers: Associations with age and left ventricular remodeling
(John Wiley & Sons Inc, 2019-02)
Background: Aging-related arterial stiffness is associated with substantial changes in global and local arterial pressures. The subsequent early return of reflected pressure waves leads to an elevated left ventricular (LV) ...
