  • Bloom syndrome
    Bloom syndrome (often abbreviated as BS in literature), also known as Bloom-Torre-Machacek syndrome, is a rare autosomal recessive disorder characterized by short stature, predisposition to the development of cancer and genomic instability.
  • Collagen
    Collagen /ˈkɒlədʒᵻn/ is the main structural protein in the extracellular space in the various connective tissues in animal bodies.
  • Mitochondrial DNA
    Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, adenosine triphosphate (ATP).
  • Biological immortality
    Biological immortality refers to a stable or decreasing rate of mortality from senescence, thus decoupling it from chronological age.
  • Calorie restriction
    Calorie restriction (CR), or caloric restriction, or energy restriction, is a dietary regimen that reduces calorie intake without incurring malnutrition or a reduction in essential nutrients.
  • Neurodegeneration
    Neurodegeneration is the umbrella term for the progressive loss of structure or function of neurons, including death of neurons.
  • Progeria
    Progeria is an extremely rare genetic disorder in which symptoms resembling aspects of aging are manifested at a very early age.
  • International Day of Older Persons
    The International Day of Older Persons is observed on October 1 each year.
  • Retirement home
    A retirement home – sometimes called an old people's home or old age home, although this term can also refer to a nursing home – is a multi-residence housing facility intended for senior citizens.
  • Macular degeneration
    Macular degeneration, also known as age-related macular degeneration (AMD or ARMD), is a medical condition which may result in blurred or no vision in the center of the visual field.
  • Oxidative stress
    Oxidative stress reflects an imbalance between the systemic manifestation of reactive oxygen species and a biological system's ability to readily detoxify the reactive intermediates or to repair the resulting damage.
  • Telomerase
    Telomerase, also called terminal transferase, is a ribonucleoprotein that adds a species-dependent telomere repeat sequence to the 3' end of telomeres.
  • Sirtuin
    Sirtuin or Sir2 proteins are a class of proteins that possess either mono-ADP-ribosyltransferase, or deacylase activity, including deacetylase, desuccinylase, demalonylase, demyristoylase and depalmitoylase activity.
  • Reactive oxygen species
    Reactive oxygen species (ROS) are chemically reactive chemical species containing oxygen.
  • RecQ helicase
    RecQ helicase is a family of helicase enzymes initially found in Escherichia coli that has been shown to be important in genome maintenance.
  • Potato cyst nematode
    Potato root nematodes or potato cyst nematodes (PCN) are 1-mm long roundworms belonging to the genus Globodera, which comprises around 12 species.
  • Progeroid syndromes
    Progeroid syndromes (PS) are a group of rare genetic disorders that mimic physiological aging, making affected individuals appear to be older than they are.
