Excessive mechanical strain accelerates intervertebral disc degeneration by disrupting intrinsic circadian rhythm [PDF]
Experimental & Molecular Medicine, 2021 AbstractNight shift workers with disordered rhythmic mechanical loading are more prone to intervertebral disc degeneration (IDD). Our results showed that circadian rhythm (CR) was dampened in degenerated and aged NP cells. Long-term environmental CR disruption promoted IDD in rats.

Excessive accelerations in bridges for Korea high-speed railway [PDF]
WIT Transactions on Modelling and Simulation, Vol 46, 2007 When the Korean high-speed train (KTX) runs over a high-speed railway bridge, the high-speed railway bridge gives quite a large acceleration response. Local vibration at the large cross section, the impact from equally spaced sleepers, the vibration due to elastomeric bearings, and the vibration from the train itself are the causes of this acceleration

Energy excess is the main cause of accelerated aging of mammals
Oncotarget, 2015 The analysis of cases of unusually high longevity of naked mole rats and an alternative explanation of the phenomenon of calorie restriction effects in monkeys allowed for postulating that any factor preventing an excess of energy consumed, leads to increased lifespan, both in evolutionary and an individual lifetime scale.
