A loading system for providing a cell suitable for delivery of an agent to a vertebrate, the system comprise a loading module for loading a cell with an agent; and a sensitization module in fluid communication with the loading module, the sensitization module for sensitizing a cell to an energy field, such that said cell is induced to release the agent upon exposure to said energy field. The coating solution is capable of forming, from an inexpensive starting material such as tin oxide or tin chloride, strong tin oxide film endowed with excellent conductivity and transparency. , a belt, is to be provided that causes no increase in size and cost of the device and sufficiently stabilizes the velocity of the image carrying member upon fluctuation in load, so as to suppress or prevent formation of an image defect referred to as so-called \u201cbanding\u201d. The driver is pivotally connected to one end of the base and is formed with a press plate. The methods and apparatuses involve a system controller for a plurality of nonvolatile memory devices in the nonvolatile memory system that is capable of protecting data using two layers of data protection, including inter-card card stripes and intra-card page stripes. The knitting repair tool of the present invention comprises a first hook and a second hook at opposite ends of a relatively short elongated shaft for recovering a first stitch and for recovering a second stitch in a knitted article, wherein the second stitch is recovered after the first stitch has been recovered, without releasing the recovered first stitch from the knitting repair tool.
