AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Peripheral nerve injury is a serious problem affecting significantly patients' life. Autografts are the "gold standard" used to repair the injury gap, however, only 50% of patients fully recover from the trauma. Artificial conduits are a valid alternative ...
The surface structure of self-assembled monolayers of hexanethiolate (HT) on the Au(100)-(1 x 1) surface has been studied by density functional theory (DFT) calculations and their results compared to scanning tunneling microscopy (STM) and X-ray photoelect ...
Silicon and Silicon carbide particles have been investigated by the mean of infrared (IR) spectroscopy and X-ray photoelectron spectroscopy (XPS) to establish their surface states. The results of this research are based on the estimation of the area under ...
Silicon dioxide (SiO2) films grown on silicon monocrystal (Si) substrates form the gate oxides in current Si-based microelectronics devices. The understanding at the atomic scale of both the silicon oxidation process and the properties of the Si(100)-SiO2 ...
Regenerative peripheral nerve interfaces are particularly invasive implant devices. They rely on the growth of axons from transected nerve stumps through electrode-bearing structures in order to establish highly efficient communication channels with the ne ...
To what extent, how and when axons respond to injury in the highly interconnected grey matter is poorly understood. Here we use two-photon imaging and focused ion beam-scanning electron microscopy to explore, at synaptic resolution, the regrowth capacity o ...
Objective. As artificial prostheses become more refined, they are most often used as a therapeutic option for hand amputation. By contrast to extra- or intraneural interfaces, regenerative nerve electrodes are designed to enable electrical interfaces with ...
Spinal cord injury (SCI) results in a severing of axonal connections that leads to permanent sensorimotor deficits. In cases of incomplete injury, rehabilitation paradigms have been reported to be successful in improving behavioral outcome in humans with S ...
CNS regeneration is limited by lesion-induced neuronal apoptosis and an environment inhibiting axonal elongation. Inhibition of ROCK has been previously shown to promote regeneration in retinal ganglion cells (RGC) whereas Cdk5 inhibition mainly promoted s ...
We have fabricated a soft silicone structure to support the regeneration of a sciatic nerve. The device consists of 70 parallel (120 x 110 mu m(2)) channels through which axons extend and then reconnect to the muscles on the other side of the device. Throu ...
