OBSOLETE. A nucleolar fragmentation process that gives rise to multiple rounded structures and that occurs in conjunction with increasing age in dividing cells.
OBSOLETE. Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) occurring in non-dividing cells as they age as a result of oxidative stress, where the change varies according to the age of the cell or organism.

OBSOLETE. Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) occurring in non-dividing cells as they age as a result of reactive oxygen species, where the change varies according to the age of the cell or organism.
OBSOLETE. A process of general metabolic decline that arises in dividing cells as they age, and alters cellular metabolism to cause a decline in cell function.
