  A teratoma is generally defined as a tumor arising from pluripotent cells, and it is precisely the heterogeneity of tissues present in such a tumor that best characterizes it; it is also commonly accepted that a teratoma must contain derivatives of more than one blastodermic (...)

• abscess
  9 June 2004

  abcesses
  Definition: Abscesses are localized collections of purulent inflammatory tissue caused by suppuration buried in a tissue, an organ, or a confined space. They are produced by deep seeding of pyogenic bacteria into a tissue.
  Abscesses have a central region that appears as a mass of necrotic leukocytes and tissue cells. There is usually a zone of preserved neutrophils around this necrotic focus, and outside this region vascular dilation and parenchymal and fibroblastic proliferation (...)

• mismatch repair diseases
  15 December 2003

  microsatellite instability, MSI-H, DNA microsatellite instability, MSI, mismatch-repair deficiency; MMR diseases; DNA Mismatch Repair Protein Deficiency
  Definition: A cause for genetic instability is the frequent appearance of mismatches on the double helix of DNA. (DNA mismatch repair)
  Base-base mismatches
  Base-base mismatches and small loops may occur during most of the main mechanism that process DNA, that is, replication, recombination and repair itself. From bacteria to eukaryotes, (...)

  18 November 2003

  Adj. cardiomyocytic; cardiac myocytes, cardiomyocyte

  NCK2-18: normal endomyocardial biopsy (PAS)
  NCK2-19: normal endomyocardial biopsy (PAS diastase)
  Definition: The myocardium is composed primarily of a collection of specialized muscle cells called cardiac myocytes or cardiomyocytes.
  They are arranged largely in a circumferential and spiral orientation around the left ventricle, the chamber that pumps blood to the systemic circulation.
  Cardiac myocytes have five (...)

• TP53
  30 September 2003

  P53, p53
  Definition: p53 is a nuclear phospho-protein which, in response to DNA damage, slows progression through the cell cycle and initiates apoptosis if damage is severe. The tumor suppressor gene TP53 is altered in the majority of cancers.
  p53 is required for the G1/S checkpoint and is a main component of the G2/M checkpoint. The p53 protein causes cell-cycle arrest and apoptosis. It acts mainly through p21 to cause cell-cycle arrest.
  It causes apoptosis by inducing the transcription (...)
