glutathione cycle pentose phosphate pathway Pentose phosphate pathway - Wikipedia

Specifically, low linear energy transfer (LET) IRs, including -rays and X-rays, induce the excitation and ionization of water molecules, leading to the production of ROS (mainly free radicals)

Most adults need between 7 to 9 hours of sleep per night to function optimally and maintain good health

In compensated cirrhosis, circulating melatonin levels have been reported to correlate with disease-related parameters (details relating to blood parameters affected by oxidative stress, inflammation, and liver problems such as malondialdehyde (MDA), C-reactive protein (CRP), TNF- (tumor necrosis factor-), ALT (alanine aminotransferase), AST (aspartate aminotransferase), and bilirubin are noted to be associated with levels of circulating melatonin), which suggest a compensation and potentially protective role as the disease progresses [98]

We may increase life span through a slower cell growing/metabolism, a slower loss of physiologic reserve capacity, a shift of cellular metabolism from cell proliferation to repair activities and a decrease in accumulation of senescent cells
