CA-125

(noun)

member of the mucin family glycoproteins that serves as a tumor marker or biomarker and may be elevated in the blood of some patients with specific types of cancers.

Examples of CA-125 in the following topics:

  • Ovarian Cysts

    • Additionally, a blood test may be taken before surgery to check for elevated CA-125, a tumor marker, which is often found in increased levels in ovarian cancer, although it can also be elevated by other conditions resulting in a large number of false positives.

  • Cancer Proteomics

    • Some examples of protein biomarkers used in cancer detection are CA-125 for ovarian cancer and PSA for prostate cancer.

  • Effect of a Common Ion on Solubility

    • In areas where water sources are high in chalk or limestone, drinking water contains excess calcium carbonate CaCO3.
    • What is the solubility at 25°C of calcium fluoride (CaF2): (a) in pure water; (b) in 0.10 M calcium chloride (CaCl2); and (c) in 0.10 M sodium fluoride (NaF)?
    • With such a small solubility product for CaF2, you can predict its solubility << 0.10 moles per liter.
    • If we go back and compare, only 4.7 percent as much CaF2 will dissolve in 0.10 M CaCl2 as in pure water:
    • since fluoride ions are in NaF as well as in CaF2.

  • Controlling the Components of Working Capital

    • Increasing CA or decreasing CL increases WC, and vis versa.
    • Cash is a CA.
    • Inventory is a CA.
    • Credit extended to customers (accounts receivable) is a CA.
    • By adjusting these four primary influencers on CA and CL, management can change WC to a desirable level.
