An information-reading element may be provided, which can be made small, and allows the number of adjustment steps to be reduced, and an information-reading device may be provided. 6 times the outer diameter of the rotors or where one of the rotors has a larger outer diameter than the other rotors the outer diameter of the larger diameter rotor. The sum logic is configured to generate a first sum signal from a first set of three input signals. Counter electrodes can face the cathode electrodes, can be coplanar with the cathode electrodes, and can be coupled to the gate electrodes. Also provided are methods of diagnosing or determining susceptibility to ADP-glucose receptor associated conditions, by detecting in a sample from the individual expression of ADP glucose receptor nucleic acid molecules or polypeptides.
