From life to death--the struggle between chemistry and biology during aging: the Maillard reaction as an amplifier of genomic damage.

abstract：:We studied vascular function in quiescent aortas from senescence-accelerated resistant (SAM-R1) and prone (SAM-P8) mice. Myographical studies of thoracic aorta segments from 6-7 month-old mice showed that the contractility of SAM-P8 aortas was markedly higher than that of SAM-R1 after KCl depolarization or phenylephri...
