Abstract: The present disclosure relates to a computer generated 3D virtual environment for improving memory (e.g. spatial, temporal, spatial-temporal, working and short-term memory). In an aspect, there is provided a computer-implemented method for generating a 3D virtual reality (VR) environment for improving spatial memory. In an embodiment, the method comprises executing at least one VR memory training module including one or more memory training tasks to be performed within a navigable three-dimensional (3D) environment; displaying a navigable 3D environment via an output to a display; and receiving an input from an interactive navigational controller. In another embodiment, the method may further comprise performing one or more scans of brain activity, whereby, the effectiveness of the at least one VR memory training module in targeting a region of the brain can be measured.

Abstract: A process of preparing articles having gaseous NO sequestered therein is disclosed, as well as articles prepared thereby. Also disclosed are articles having gaseous NO sequestered therewithin and having reduced amount of oxygen-containing and/or nitrogen-containing reactive species. Also disclosed are processes of preparing packaged articles having a non-gas permeable package that comprises gaseous NO therein and packaged articles made therefrom. Also disclosed are charging devices which can be utilized in the above-described processes. The articles prepared by the above-described processes are preferably medical devices such as indwelling catheters, intubation devices and tampons. Tampons having sequestered therein gaseous NO, uses thereof and processes of preparing same are also disclosed.
