The disclosure relates to a Complex Intermediate Frequency -based receiver adapted to process a received signal comprising a signal component at a desired frequency and a signal component as an image frequency. The invention is a system for detecting and analyzing clinical pictures and the causes thereof and for determining proposals for appropriate therapy, which can lead to a diagnosis and a corresponding therapy proposal even in the case of complex clinical causes and pictures, said proposal involving a maximum diagnostic certainty and minimum risk for the patient. The crystal oscillator is supported by top surfaces of a transistor and a varicap diode that are the highest among the circuit components mounted on the circuit board. To that end, the second element is elongated and adapted to receive circularly polarized radio signals by operation with linear polarization. Therefore the compounds of the formula regulate the effect of chemokinechemokine receptor, they are used for prevention and treatment of various inflammatory diseases, asthma, atopic dermatitis, urticaria, allergic diseases, nephritis, nephropathy, hepatitis, arthritis or rheumatoid arthritis etc.
