Dear J.R. First off let me say that I am not an expert in biology. My expertise is in computers. But from my search of the archive and checking some other sources I do believe o say that my post from my WWW search DOES indeed have to do with NADH!! Even though NADH is not specifically mentioned in that Abstract, except in the title, NADH deficiency is mentioned in other papers in the archives that also mention a defect in the mitochondrial energy (respiratory) function. If you expertise is in this field and I am incorrect, I appolize. Otherwise hopefully someone more knownedgeable will set us both straight! Eric M. Adams [log in to unmask]
