[Biochemical basis of aging]

W Rotzsch

    Zeitschrift Fur Die Gesamte Innere Medizin Und Ihre Grenzgebiete
    |February 15, 1976

    Summary

    Biological aging, the structural and functional decline from birth to death, begins early in life. This process, termed "vitability," affects all cell types, leading to decreased organismal function.

    Area of Science:

    • Gerontology
    • Cell Biology
    • Human Physiology

    Context:

    • Biological aging is a fundamental process affecting all living organisms.
    • Understanding aging is crucial for addressing age-related diseases and promoting healthy longevity.
    • Early life changes indicate aging is a continuous process, not solely a late-life phenomenon.

    Purpose:

    • To define biological aging as a continuous process from birth to death.
    • To highlight that aging-related changes commence early in the first third of life.
    • To introduce the concept of "vitability" as a measure of declining biological functional capacity.

    Summary:

    • Biological aging encompasses structural and functional changes from individual autonomy to death.
    • Aging processes initiate in the first third of life, concurrent with developmental changes.
    • This decline in biological functional capacity is termed "vitability" and affects both post-mitotic and intermitotic cells.

    Impact:

    • Provides a comprehensive definition of biological aging.
    • Establishes that aging is a lifelong process with early-onset changes.
    • Introduces a quantifiable measure (vitability) for assessing organismal decline.
