The present invention concerns new chondroitin sulfate compositions with a twofold therapeutic action. The device generally includes a matrix viewing display, and a set of two lenticular networks or arrays, one of which is called a converting lenticular network or array. The invention also relates to vaccines containing the novel proteins of the invention. Auxiliary thread-handling or incrementing and knot-tying devices are also disclosed. A total impedance of the first half of the radiation electrode and the power supply conductor and a total impedance of the second half of the radiation electrode and the ground conductor can substantially match to one another, so that resonance between the halves of the radiation electrode can be enhanced and a wider bandwidth can be realized.
