Mitochondrial DNA are, however, constantly under mutational pressure due to oxidative stress imposed by radicals generated by oxidative phosphorylation or an imbalance in the antioxidant defense system in aging or disease processes [ 1].
Reconciling with moderates is key to diminishing the oppression imposed by the radicals and shutting down a conveyor belt for future terrorists.

SIF thus has the potential to provide an integrated measure of stresses imposed by aging, glycemic exposure, and free-radical oxidation, all of which are interrelated.
Endogenous causes of mutation include depurination and depyrimidation of DNA; proofreading and mismatch errors during DNA replication; deamination of 5-methylcytosine to produce C to T base pair substitutions; and damage to DNA and its replication imposed by products of metabolism (notably oxidative damage caused by oxygen free radicals).
Nicotine induces free radical generation and contributes a major proportion of the net oxidative stress imposed by tobacco use (Bhagwat et al. 1998; Newman et al. 2002; Qiao et al. 2005; Yildiz et al. 1999).
But what is being imposed by the lending institutions is not a series of sensible "reforms", but the establishment and micromanagement of radical 'free market' economics.
