Abstract
Electrical Impedance scanning (EIS) is a new technique in which moderate
variations in capacitance values are reflected by the cells of various type of
normal membrane. The malignant membrane, in contrast, in EIS demonstrates
significant capacitance relaxation phenomena concomitant with α dispersion in
the low audio frequency range. The author has endeavored to establish the above
stated phenomena. In his experimental setup, the lipoprotein constituent of the
membrane was dissolved in acetone solvent and the interaction of the dissolved
lipoprotein in the presence of electrical stimuli in the lower audio frequency
range at room temperature of about 25ºC was studied. The capacitance relaxation
phenomena concomitant with α dispersion in the malignant membrane for
subjects below and above 50 years has been simulated in MATLAB 6.5. The
model incorporates a modified homeostat comprising of a homeostat and
transduction phase in the feedback path and it represents the interaction of the
lipoprotein in a malignant membrane associated with α dispersion mediated
through capacitance relaxation phenomena. Results from the output of the model
are in close conformity with the capacitance relaxation phenomena, which
suggest an adjunctive detection modality in the differentiation of membrane
malignancy that is equivocal on Ultrasonography.
Keywords: capacitance relaxation, malignant membrane, α dispersion, modified
homeostat.
