  metastasis to ovary
  The GI tract is the most common primary site to metastasize to the ovary; this is followed by breast cancer, and then endometrial cancer.
  Carcinomatous components of carcinosarcomas metastasize more frequently than the sarcomatous components.
  For the GI tract, colon mets. are most common, followed by stomach mets. Metastasis from the gyne tract are significantly less frequent.
  For the gynecologic organs, most commonly mets. to the ovaries are from the uterine cervix. (...)

• Chromatin
  13 July 2003

  Definition: Chromatin is the DNA/protein/RNA complex extracted from eukaryotic lysed interphase nuclei. Just which of the multitudinous substances present in a nucleus will constitute a part of the extracted material will depend in part on the technique each researcher uses. Furthermore, the composition and properties of chromatin vary from one cell type to the another, during development of a specific cell type, and at different stages in the cell cycle.
  Chromatin is found inside the (...)
