The present invention is drawn toward an ink-jet ink, comprising an aqueous liquid vehicle having acid-functionalized polymer colloid particulates and polymer-attached pigment colorants dispersed in the liquid vehicle. A lock reinforcement is disposed at a lower side of a vehicle front of the hood inner panel. The metadata identifies events of importance in the video and audio segments, which may then be applied to the editing process. Diagnostic methods and kits utilizing the media are also provided, as well as treatment methods utilizing spent culture supernatant and cell extracts, or components thereof.
