The present invention provides an anthracene derivative represented by the following general formula. The support element has a pedal and a rotatable axle. This tube also includes a lumen that is continuous from the proximal to the distal end, and has an end hole in the distal end that is in fluid communication with the lumen. The terminal is further operable for configuring itself to operate according to an operational parameter associated with the characterizing parameter of the peripheral device. 0 wt % of a galacto-oligosaccharide and at least 0.
