An alternative methodology to predict aging effects on the mechanical properties of glass fiber reinforced cement (GRC) [PDF]
, 2012 The effect of three different aging methods (immersion in hot water, freeze–thaw cycles and wet–dry cycles) on the mechanical properties of GRC were studied and compared.

Rheological aging and rejuvenation in solid friction contacts
, 2002 We study the low-velocity (0.1--100 $\mu$m.s$^{-1}$) frictional properties of interfaces between a rough glassy polymers and smooth silanized glass, a configuration which gives direct access to the rheology of the adhesive joints in which shear localizes.

Telomerase Protects Werner Syndrome Lineage-Specific Stem Cells from Premature Aging
Stem Cell Reports, 2014 Werner syndrome (WS) patients exhibit premature aging predominantly in mesenchyme-derived tissues, but not in neural lineages, a consequence of telomere dysfunction and accelerated senescence.

ON RADIATION-INDUCED AGING: ACCELERATED OR PREMATURE AGING
Radiation Protection Dosimetry, 2022 Abstract The concept of radiation-induced aging is revisited from the viewpoint of a mathematical model. The effect of radiation on carcinogenesis is treated based on the Armitage–Doll multi-stage theory. The formula obtained for cancer incidence rate indicates that radiation dose can be explained in terms of time.

Hematopoietic (stem) cells—The elixir of life?
FEBS Letters, EarlyView.The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.
