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 ...

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 ...

Multiciliogenesis: multicilin directs transcriptional activation of centriole formation

Pierre Gönczy, Fernando Romero Balestra

During differentiation of multiciliated cells, numerous centrioles are generated in each cell to act as templates for the formation of a corresponding number of cilia. A new study reveals that multicilin, a protein required for multiciliogenesis, is a key ...

Deletion of glutamate dehydrogenase 1 (Glud1) in the central nervous system affects glutamate handling without altering synaptic transmission

Rolf Gruetter

Glutamate dehydrogenase (GDH), encoded by GLUD1, participates in the breakdown and synthesis of glutamate, the main excitatory neurotransmitter. In the CNS, besides its primary signaling function, glutamate is also at the crossroad of metabolic and neurotr ...

Calculation of intracranial pressure in human brain using Darcy's and Biot's models

Jean-Marie Drezet, Kamal Shahim

Cerebrospinal fluid (CSF) is a colourless liquid that fills the ventricular space and serves several functions like buoyancy, chemical stability and protection. CSF is produced within the ventricles and partly by the ependyma cells. Part of it seeps toward ...

Substrate arrays of iridium oxide microelectrodes for in-vitro neuronal interfacing

Philippe Renaud, Henry Markram, Marc Olivier Heuschkel, Michele Giugliano, Shady Didier Gawad

The design of novel bidirectional interfaces for in vivo and in vitro nervous systems is an important step towards future functional neuroprosthetics. Small electrodes, structures and devices are necessary to achieve high-resolution and target-selectivity ...

Effects of dynamic compression on lentiviral transduction in an in vitro airway wall model

Melody Swartz, Alice Anna Tomei

Asthmatic patients are more susceptible to viral infection, and we asked whether dynamic strain on the airway wall (such as that associated with bronchoconstriction) would influence the rate of viral infection of the epithelial and subepithelial cells. To ...

Evaluation of an intrathecal immune response in amyotrophic lateral sclerosis patients implanted with encapsulated genetically engineered xenogeneic cells

Patrick Aebischer

A phase I/II clinical trial has been performed in 12 amyotrophic lateral sclerosis (ALS) patients to evaluate the safety and tolerability of intrathecal implants of encapsulated genetically engineered baby hamster kidney (BHK) cells releasing human ciliary ...
