Aging and endothelin: Determinants of disease

open access: yesLife Sciences, 2014
Since the beginning of the 20th century human life expectancy has doubled to more than 80 years, and growth and aging of the world population now represent major challenges for healthcare providers, political decision makers, and societies. Cellular senescence is associated with a general, pro-inflammatory state, which represents the common denominator

Epigenetic-aging-signature to determine age in different tissues

open access: yesAging, 2011
All tissues of the organism are affected by aging. This process is associated with epigenetic modifications such as methylation changes at specific cytosine residues in the DNA (CpG sites). Here, we have identified an Epigenetic-Aging-Signature which is applicable for many tissues to predict donor age.

Genetic determinants of proteomic aging

open access: yesnpj Aging
Abstract Changes in the proteome and its dysregulation have long been known to be a hallmark of aging. We derived a proteomic aging trait using data on 1459 plasma proteins from 44,435 UK Biobank individuals measured using an antibody-based assay.

Molt patterns, aging, and sexing criteria for ten temperate Neotropic bird species: an important resource for bird monitoring programs

open access: yesJournal of Field Ornithology
Within avian biology, molt represents a crucial and energetically demanding process that involves the periodic replacement of plumage. A comprehensive understanding of molt patterns enables bird monitoring programs and conservation efforts.
