The survey, which was requested by Senators Joseph I. Lieberman, Democrat of Connecticut, and James M. Jeffords, the Vermont independent, gathered responses from 44 states on the section of the Clean Air Act governing aging coal-burning plants, New Source Review.
In the case on Monday, the court refused to hear an appeal by the federal government that would have applied New Source Review, a controversial section of the Clean Air Act governing aging coal-burning plants, to power plants owned by the Tennessee Valley Authority.
However, the mechanisms governing age-related adipose tissue dysfunction and the limited regenerative capacity of adipose tissue remain to be elucidated.
The processes governing age-specific transitions in motor behavior are not fully understood.
Recently, the O-methyltransferase PaMTH1 emerged as a new component of the complex network governing ageing and lifespan control in P. anserina.
The basic biochemical mechanisms are so common in all living world that there are good reasons to expect that the mechanisms governing aging are also universal.
Therefore, developing effective strategies aimed at improving quality and duration of life in current calorie-rich conditions will require a better understanding of the mechanisms (cells and molecules) governing aging and protecting from diet-induced metabolic imbalance.
Moreover, the work provides additional and very promising perspectives for the development of medical strategies to intervene into the part of the molecular network governing aging via mitochondrial pathways involved in the control of apoptosis as they have been put forward earlier [ 7, 13].
Evolutionary biologists believe, on largely theoretical grounds, that many genes govern aging and that there can be no single mechanism of aging, whether the one Dr. Guarente suggests or any other.
The E.P.A. announced in November that it was going to suspend investigations into utilities after the administration loosened the sections of the Clean Air Act that govern aging coal-burning power plants.
Using his very own genome as a guide, Dr. Collins covers the familiar territory of cancer-associated genes, then heads for the more arcane regions that govern aging and susceptibility to various infections.
