Lifting column, preferably for height adjustable tables, said lifting column comprising at least two relative to each other telescopically arranged members. A second terminal electrode has a first electrode portion disposed on a second face and connected to a second internal electrode, and a second electrode portion disposed on the third face and connected to the first electrode portion. When the processed acquired data is displayed on a logarithmic scale, the pseudo-random sub-LSB values fill in the gaps between discrete power levels, thereby eliminating intensity banding and providing a smooth, visually pleasing display. The respective ends of the first and second shell portions are covered by a first plate portion and a connecting portion. In addition, evidence that r150 is released from the cell surface by an endogenous phospholipase C is provided.
