Sonication, Calcium, and Peptides Have Systematic Effects on the Nonlinear Dynamics of Tyrosine Hydroxylase Activity

摘要

This is a very carefully executed companion paper to the TRH-tryptophan hydroxylase study (no. 3) discussed above demonstrating for caudate dopammergic tyrosine hydroxylase studied under conditions of far-from-equilibrium tetrahydrobiopterin concentrations that specific peptides and ion-ligands can both confer and destroy coherence in the kinetic fluctuations using power spectra and Hausdorf measure. Example of the use of non-parametric statistics on 'momentless' data distributions using these descriptors serves to exemplify approaches to data which laboratories (including us in the past) might have thrown away. It again deals specifically with the issue of complexity and coherence in dynamics with respect to chemical communications.
