Abstract: The disclosure provides, inter alia, dual-layer, semi-permeable, fibrosis-resistant, hydrogel polymer enclosures, optionally containing cells, such as mammalian cells, where the enclosures are suitable for administration to a subject in need thereof and further wherein the enclosure are scalable for large volumes of delivered cells. The disclosure further provides methods of making and using the enclosures, for example, in therapeutic methods, such as treating disorders of the liver or other cells and organs treatable with, for example secretory and/or catalytic cells.

Abstract: A solution for concealing confidential information that is printed at the point of sale in a game of chance utilizing a more common type printer designed for printing on a standard grade and biodegradable direct thermal paper. This system can print and cut each individual ticket in variable lengths. The unique and innovative concept of this new system allows a second and separate biodegradable substrate to be collated in a continuous stream over top of the printed ribbon before it is cut away and delivered into the presenter. The second substrate contains a strip of a specially formulated adhesive and is adhered to the top surface of the printed ribbon as the two substrates join together while passing through mechanical nip rollers. The confidential printed information is now covered and the combined substrates are cut and delivered as one ticket unit. The ticket information is revealed by easily peeling away the adhered top layer.
