Karabanov, V. V. Shvartsman, M. R. Soares, V. Sablinskas, A. N. Salak, D. C. Lupascu and J. Banys, J. Mater. Chem. A, 2020, 8, 14015

Dominik Józef Kubicki

In this reply, we address the concerns that were raised about our paper on CsPbBr3 single crystals. M. Szafranski criticized the dielectric and DSC data in our original paper claiming that they were affected by the experimental artefacts or poor quality of ...

Spatiotemporal stimulation strategies in neuroprostheses to improve locomotion after spinal cord injury

Jérôme Gandar

Spinal cord injury (SCI) disrupts communication within central nervous system and lead to range of neurological disorders including paralysis. Current rehabilitation strategies to restore locomotion are poorly effective in people with severe SCI. Epidural ...

Advantages of soft subdural implants for the delivery of electrochemical neuromodulation therapies to the spinal cord

Stéphanie Lacour, Marco Capogrosso, Grégoire Courtine, Eduardo Martin Moraud, Pavel Musienko, Ivan Rusev Minev, Nikolaus Wenger, Jérôme Gandar, Polina Shkorbatova, Nathan Antoine Greiner

Objective. We recently developed soft neural interfaces enabling the delivery of electrical and chemical stimulation to the spinal cord. These stimulations restored locomotion in animal models of paralysis. Soft interfaces can be placed either below or abo ...

Electronic dura mater soft, multimodal neural interfaces : technology, integration and implementation to surface implants

Arthur Edouard Hirsch

Neuroprosthetic devices are engineered to study, support or replace impaired functions of the nervous system. The neural interface is an essential element of neuroprosthetic systems as it allows for transduction of signals and stimuli of desired functions ...

Surface-based characteristics of the cerebellar cortex visualized with ultra-high field MRI

Wietske Van der Zwaag, Gunnar Krüger, Cristina Granziera, Guillaume Bonnier, Kieran O'Brien, Yohan Boillat, Mario Joao Fartaria de Oliveira

Although having a relatively homogeneous cytoarchitectonic organization, the cerebellar cortex is a heterogeneous region characterized by different amounts of myelin, iron and protein expression profiles. In this study, we used quantitative T1 and T2* mapp ...

Multimodal microstructure imaging: joint T2-relaxometry and diffusometry to estimate myelin, intracellular, extracellular, and cerebrospinal fluid properties

Jean-Philippe Thiran, Alessandro Daducci, Erick Jorge Canales Rodriguez, Marco Pizzolato

We propose a multimodal joint estimation that aims at exploiting the complementary information of diffusion and multi-echo spin echo data to disentangle the contributions and properties of the main tissue microstructure compartments. We recovered T2, diffu ...

Studying cyto and myeloarchitecture of the human cortex at ultra-high field with quantitative imaging: R1, R⁎2 and susceptibility

Rolf Gruetter, José Pedro Rebelo Ferreira Marques, Diana Khabipova

In this manuscript, the use of quantitative imaging at ultra-high field is evaluated as a mean to study cyto and myelo-architecture of the cortex. The quantitative contrasts used are the longitudinal relaxation rate (R1), apparent transverse relaxation rat ...

Overcoming the resolution limit in retinal imaging using the scattering properties of the sclera

Demetri Psaltis, Christophe Moser, Dino Carpentras, Timothé Laforest

In-vivo imaging of the eye's fundus is widely used to study eye's health. State of the art Adaptive Optics devices can resolve features up to a lateral resolution of 1.5 um. This resolution is still above what is needed to observe subcellular structures su ...

Perivascular M2 macrophages stimulate tumor relapse after chemotherapy

Michele De Palma, Ioanna Keklikoglou

Tumor relapse after chemotherapy-induced regression is a major clinical problem, because it often involves inoperable metastatic disease. Tumor-associated macrophages (TAM) are known to limit the cytotoxic effects of chemotherapy in preclinical models of c ...

The Impact of Spinal Cord Nerve Roots and Denticulate Ligaments on Cerebrospinal Fluid Dynamics in the Cervical Spine

Bryn Andrew Martin

Cerebrospinal fluid (CSF) dynamics in the spinal subarachnoid space (SSS) have been thought to play an important pathophysiological role in syringomyelia, Chiari I malformation (CM), and a role in intrathecal drug delivery. Yet, the impact that fine anatom ...
