Large, majestic trees are iconic symbols of great age among living organisms. Published evidence suggests that do not die because genetically programmed senescence in their meristems, but rather killed by an external agent or a disturbance event. Long tree lifespans therefore allowed specific combinations life history traits within realized niches support resistance to, avoidance of, extrinsic ...
AIM Genetic factors play important roles in determining human lifespan. Although some "longevity genes" have been identified to be implicated in human longevity, many disease-associated variants were also observed in the long-lived individuals. The oldest old and their offspring usually have a lower prevalence of age-related diseases, which is likely attributed to a reduction or an absence of d...
Longevity as a complex life-history trait shares an ontogenetic relationship with other quantitative traits and varies among individuals, families and populations. Heritability estimates of longevity suggest that about a third of the phenotypic variation associated with the trait is attributable to genetic factors, and the rest is influenced by epigenetic and environmental factors. Individuals ...
Healthy longevity has been an unremitting pursuit of human, but its genetic and the environment causes are still unclear. As longevity population is a good healthy aging model for understanding how the body begin aging and the process of aging, and plasma lipids metabolism and balance is a very important to life maintain and physiologic functional turnover. It is important to explore how the ef...
