Compliant vascular grafts and methods of use

Compliant vascular grafts for implantation in the vasculature are provided. The compliant vascular grafts are designed to expand longitudinally and radially within a blood vessel, such as an artery, and is expected to be particularly well suited for treati ...

Mapping the site-specific accuracy of loop-based local pulse wave velocity estimation and reflection magnitude: a 1D arterial network model analysis

Nikolaos Stergiopoulos, Patrick Segers

Objective: Local pulse wave velocity (PWV) can be estimated from the waterhammer equation and is an essential component of wave separation analysis. However, previous studies have demonstrated inaccuracies in the estimations of local PWV due to the presenc ...

Inherent biomechanical traits enable infective filariae to disseminate through collecting lymphatic vessels

Melody Swartz, Marco Pisano, Witold Waldemar Kilarski

Filariases are diseases caused by arthropod-borne filaria nematodes. The related pathologies depend on the location of the infective larvae when their migration, the asymptomatic and least studied phase of the disease, comes to an end. To determine factors ...

A brain-spine interface alleviating gait deficits after spinal cord injury in primates

Silvestro Micera, Grégoire Courtine, Quentin Barraud, Jocelyne Bloch, Tomislav Milekovic, Eduardo Martin Moraud, Marco Capogrosso, Elodie Rey, Fabien Bertrand Paul Wagner, Jérôme Gandar, Jean-Baptiste Mignardot, David Allenson Borton, Simone Ellen Joze Duis

Spinal cord injury disrupts the communication between the brain and the spinal circuits that orchestrate movement. To bypass the lesion, brain-computer interfaces(1-3) have directly linked cortical activity to electrical stimulation of muscles, and have th ...

Role of a polymorphism in a Hox/Pax-responsive enhancer in the evolution of the vertebrate spine

Denis Duboule

Patterning of the vertebrate skeleton requires the coordinated activity of Hox genes. In particular, Hox10 proteins are essential to set the transition from thoracic to lumbar vertebrae because of their rib-repressing activity. In snakes, however, the thor ...

Physiological simulation of blood flow in the aorta: comparison of hemodynamic indices as predicted by 3-D FSI, 3-D rigid wall and 1-D models

Alfio Quarteroni, Nikolaos Stergiopoulos, Simone Deparis, Philippe Reymond, Paolo Crosetto

Interest in patient-specific blood-flow circulation modeling has increased substantially in recent years. The availability of clinical data for geometric and elastic properties together with efficient numerical methods has now made model rendering feasible ...

Lymphatic vasculature mediates macrophage reverse cholesterol transport in mice

Melody Swartz

Reverse cholesterol transport (RCT) refers to the mobilization of cholesterol on HDL particles (HDL-C) from extravascular tissues to plasma, ultimately for fecal excretion. Little is known about how HDL-C leaves peripheral tissues to reach plasma. We first ...

Structural strain energy function applied to the ageing of the human aorta

Nikolaos Stergiopoulos, Martin Zulliger

Stiffening of the aorta with progressing age leads to decrease of aortic compliance and thus to an increase of pulse pressure amplitude. Using a strain energy function (SEF) which takes into account the composition of the arterial wall, we have studied the ...
