Sensor-integrated ultraflexible endovascular devices

Lucio Feo Pancaldi-Giubbini

Medical interventions in the central nervous system (CNS) are challenging due to the complexity and delicacy of the brain tissue. Techniques that do not require opening the skull would alleviate patient discomfort and increase post-operative outputs. Vesse ...

Five-year follow-up of intracoronary autologous cell therapy in acute myocardial infarction: the REGENERATE-AMI trial

John Martin Kolinski, Didier Locca

Aims The long-term outcomes of the intracoronary delivery of autologous bone marrow-derived cells (BMCs) after acute myocardial infarction are not well established. Following the promising 1 year results of the REGENERATE-AMI trial (despite it not achievin ...

Sodium thiosulfate, a source of hydrogen sulfide, stimulates endothelial cell proliferation and neovascularization

Georges Wagnières, Jaroslava Joniová

Therapies to accelerate vascular repair are currently lacking. Pre-clinical studies suggest that hydrogen sulfide (H2S), an endogenous gasotransmitter, promotes angiogenesis. Here, we hypothesized that sodium thiosulfate (STS), a clinically relevant source ...

Predicting future myocardial infarction from angiographies with deep learning

Omar Raita, Pascal Frossard, Emmanuel Abbé, Ntorina Thanou, Ortal Yona Senouf, Thabodhan Mahendiran

In patients with stable Coronary Artery Disease (CAD), the identification of lesions which will be responsible of a myocardial infarction (MI) during follow-up remains a daily challenge. In this work, we propose to predict culprit stenosis by applying a de ...

Considerations for analysis of endothelial shear stress and strain in FSI models of atherosclerosis

Lydia Aslanidou

Atherosclerosis is a lipid driven chronic inflammatory disease that is characterized by the formation of plaques at predilection sites. These predilection sites (side branches, curved segments, and bifurcations) have often been associated with disturbed sh ...

The fragmentation mechanism of gold nanoparticles in water under femtosecond laser irradiation

Marcel Drabbels, Ulrich Lorenz, Pavel Olshin, Gabriele Bongiovanni, Jonathan Mark Voss, Chengcheng Yan

Plasmonic nanoparticles in aqueous solution have long been known to fragment under irradiation with intense ultrafast laser pulses, creating progeny particles with diameters of a few nanometers. However, the mechanism of this process is still intensely deb ...

Long noncoding RNA SNHG12 integrates a DNA-PK-mediated DNA damage response and vascular senescence

Johan Auwerx, Norman Lionel Moullan

Long noncoding RNAs (lncRNAs) are emerging regulators of biological processes in the vessel wall; however, their role in atherosclerosis remains poorly defined. We used RNA sequencing to profile lncRNAs derived specifically from the aortic intima of Ldlr(- ...

Metabolic fingerprints discriminating severity of acute ischemia using in vivo high-field H-1 magnetic resonance spectroscopy

Hongxia Lei, Lara Buscemi Estefanell, Mario Gaetano Lepore

Despite the improving imaging techniques, it remains challenging to produce magnetic resonance (MR) imaging fingerprints depicting severity of acute ischemia. The aim of this study was to evaluate the potential of the overall high-field H-1 MR Spectroscopy ...

Fundamentals and perspectives of ultrafast photoferroic recording

Anna Pogrebna

The ability to switch ferroics (ferro-, ferri-, antiferromagnets, ferroelectrics, multiferroics) between two stable bit states is one of the keystones of modern data storage technology. Due to many new ideas, originating from fundamental research during th ...

Mitochondrial Deacetylase Sirt3 Reduces Vascular Dysfunction and Hypertension While Sirt3 Depletion in Essential Hypertension Is Linked to Vascular Inflammation and Oxidative Stress

Johan Auwerx

Rationale: Hypertension represents a major risk factor for stroke, myocardial infarction, and heart failure and affects 30% of the adult population. Mitochondrial dysfunction contributes to hypertension, but specific mechanisms are unclear. The mitochondri ...

Broadband Quasi-Phase-Matching in All-Optically Poled Stoichiometric Silicon Nitride Waveguides

Camille Sophie Brès, Edgars Nitiss, Boris Zabelich

We show how broadband (>30nm) quasi-phase matching in all-optically poled Si3N4 waveguides provides a platform for efficient sum-frequency generation, and for femtosecond pulse processing such as fcEo detection without the need for group velocity engineeri ...
