Arterial stiffness in haemodialyzed patients: Findings and controversies
(Bentham Science Publishers, 2018-04)
Vascular research in end-stage renal diseases is an interesting field in which the characterization of arterial stiffness proved to be valuable to predict morbidity and mortality. Particularly, patients on renal replacement ...
Central-to-peripheral arterial stiffness gradient in hemodialyzed patients depends on the location of the upper-limb vascular access
(Bentham Science Publishers, 2018-11)
Background: Pulse wave velocity ratio (PWV-ratio), a measure of central-to-peripheral arterial stiffness gradient, is calculated as a quotient between carotid-femoral and carotid-radial PWV (cf-PWV/cr-PWV). This new index ...
Impact of arterial cross-clamping during vascular surgery on arterial stiffness measured by the augmentation index and fractal dimension of arterial pressure
(Springer, 2016-11)
Arterial cross-clamping is a common strategy used in vascular surgery and its duration is an independent predictor of surgical outcomes. The impact of arterial cross-clamping on the viscoelastic properties of the arterial ...
Changes in vascular function and autonomic balance during the first trimester of pregnancy and its relationship with the new-born weight
(Informa Healthcare, 2021-08)
This study aimed to evaluate vascular function changes and autonomic balance during the first trimester of pregnancy and its relationship with the new-born weight. This prospective study performed in pregnant (PG) women ...
Hemodialysis decreases carotid-brachial and carotid-femoral pulse wave velocities: A 5-year follow-up study
(Wiley Blackwell Publishing, Inc, 2015-03)
Aortic stiffness is a prognostic parameter associated with patient mortality. Vascular access creation has been shown to have effects on arterial stiffness both in the aorta and in the upper limb arteries in chronically ...
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 ...
Morphological variation of the leaves of Aechmea distichantha Lem. plants from contrasting habitats of a Chaco forest: a trade-off between leaf area and mechanical supportVariações morfológicas de folhas de plantas de Aechmea distichantha Lem. de habitats contrastantes de uma floresta do Chaco: uma compensação entre área foliar e suporte mecânico
(Universidade Federal do Rio Grande do Sul. Instituto de Biociências, 2011-12)
Several authors have reported phenotypic plasticity for bromeliad plants growing in contrasting habitats. Morphological and physiological differences at the leaf level seem to be an adaptation to water and light use, but ...
