EVALUATION OF FRACTAL PROPERTIES OF ACH-RECEPTOR CHANNELS GATING EXPOSED TO MICROWAVE FIELDS

In recent years, researchers involved in biological effects of electro magnetic fields have focused their attention on the analysis of ionic channel gating and on its kinetic behaviour. This seems to be a potent ial site of interaction at the microscopic level. Some theoretical mod els of the response of protein channels to stimulating fields have bee n developed, based on Markov models. Together with the increasing inte rest in this subject, a great amount of development of physiological r esearch has resulted from fractal theories and methodologies. Their te chniques and approaches have allowed the detection of new properties a nd characteristics of nature. In this paper, an experimental evaluatio n of the temporal self-similarity of the acetylcholine channel's curre nt signals and of its spectral properties is made, both for the standa rd situation and for the channel exposed to microwave fields. On the b asis of the theoretical Markov models, a study of these properties was also carried out, demonstrating that a Markov model with a small numb er of states can simulate some fractal properties.
