The aim of this protocol is to induce transient in vivo production of nonlethal levels of reactive oxygen species (ROS) in mouse skin, further promoting physiological responses in the tissue.

We present an in vitro model to assess olfactory ensheathing glia (OEG) neuroregenerative capacity, after neural injury. It is based on a coculture of axotomized adult retinal ganglion neurons (RGN) on OEG monolayers and subsequent study of axonal regeneration, by analyzing RGN axonal and somatodendritic markers.

This study presents a novel transcranial direct current stimulation (tDCS) protocol combined with cognitive stimulation to address post-stroke hemispatial neglect. Initial data from a pilot patient ensure the procedure's feasibility and suggest potential efficacy, providing a foundation for a future parallel, triple-blind, controlled clinical trial.
