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) ...
Imaging the transition from flat to normal subduction: variations in the structure of the Nazca slab and upper mantle under southern Peru and northwestern Bolivia
(Oxford University Press, 2016-01)
Two arrays of broad-band seismic stations were deployed in the north central Andes between 8° and 21°S, the CAUGHT array over the normally subducting slab in northwestern Bolivia and southern Peru, and the PULSE array over ...
EPR spectroscopic evidence of iron-catalysed free radical formation in chronic mountain sickness: Dietary causes and vascular consequences
(Elsevier, 2022)
Chronic mountain sickness (CMS) is a high-altitude (HA) maladaptation syndrome characterised by elevated systemic oxidative-nitrosative stress (OXNOS) due to a free radical-mediated reduction in vascular nitric oxide (NO) ...
Increases in peripheral systolic pressure levels and Z-score associate gradual aortic pressure increase and functional arterial impairment in children and adolescents
(Bentham Science Publishers, 2018-12)
Background: Arterial changes associated with children and adolescents high blood pressure (HBP) states would vary depending on the arterial type, arterial indexes considered and/or on blood pressure (BP) levels. Aims: To ...
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 ...
Early renal and vascular changes in ADPKD patients with low-grade
(Oxford University Press, 2009-12)
Background. Autosomal dominant polycystic kidney dis- ease (ADPKD) shows an increase in both urine monocyte chemoattractant protein-1 (MCP-1) and carotid intima? media thickness (CIMT) before changes in serum creatinine ...
Alterations in triglyceride rich lipoproteins are related to endothelial dysfunction in metabolic syndrome
(Pergamon-Elsevier Science Ltd, 2016-08)
Our aim was to analyze the effect of circulating triglyceride rich lipoprotein (TRL) on endothelial function in metabolic syndrome (MetS). Methods We studied 40 patients with MetS (ATPIII), divided into those presenting ...
Blood pressure control is not enough to normalize endothelial repair by progenitor cells
(American Physiological Society, 2020-11)
Patients presenting with classical cardiovascular risk factors within acceptable or average value ranges often develop cardiovascular disease, suggesting that other risk factors need to be considered. Considering that ...
