A hoist ring assembly includes an anchor subassembly with bushing, retainer and threaded fastener elements, and a loop subassembly with a lifting loop and pair of pin elements. The apparatus comprises a conversion section for converting the video signal to a progressive scan video signal, and an aspect ratio conversion section for converting an aspect ratio of the progressive scan video signal output from the conversion section and outputting the converted progressive scan video signal to a progressive scan video monitor. Quantification of change in ventricular regional wall motion asynchrony in response to a therapy provides for a means to identify candidates to receive the therapy and quantitatively predict the benefit of the therapy. The error amplifier is arranged in cooperation with the first and second square function generators such that the output of the error amplifier adjusts the tail current of the square function generators. The plurality of equations are solved to obtain estimated values of the unknown participating practitioner entity outcome indices and estimated values of the unknown participating practitioner entity type indices. Zinc gluconate or a zinc halide such as zinc chloride, zinc bromide or zinc iodide may also be included.
