• phagocytosis
  23 April 2004

  Definition: Phagocytosis is a specific form of endocytosis involving the vesicular internalization of solid particles, such as bacteria. It is therefore distinct from other forms of endocytosis such as pinocytosis, the vesicular internalization of various liquids, and recptor-dependent endocytosis.
  Phagocytosis (literally, cell-eating) is the process by which cells ingest large objects, such as cells which have undergone apoptosis, bacteria, or viruses. The membrane folds around the (...)

• cellular aging
  7 March 2004

  Cellular aging is the result of a progressive decline in the proliferative capacity and life span of cells and the effects of continuous exposure to exogenous influences that result in the progressive accumulation of cellular and molecular damage. Structural and Biochemical Changes with Cellular Aging
  A number of cell functions decline progressively with age.
  Oxidative phosphorylation by mitochondria is reduced, as is synthesis of nucleic acids and structural and enzymatic proteins, (...)

  Final steps
  The final stages of mitosis begin in anaphase, when the mitotic spindle segregates the duplicated chromosomes. Mitotic exit is then completed by disassembly of the spindle and packaging of chromosomes into daughter nuclei.
  The successful (...)
