What's the difference between apheresis and extraction?

Apheresis


Definition:

  • (n.) The dropping of a letter or syllable from the beginning of a word; e. g., cute for acute.

  • (18) Optimally adjusted anticoagulation under LDL apheresis is essential for successful treatment: Excessive anticoagulation exposes the outpatient to the risk of uncontrolled hemorrhage, insufficient anticoagulation may shorten the duration of utilization of the immune-adsorption columns.
  • (19) To assure that apheresis procedures are carried out in a safe, efficient and appropriate manner with minimum risk and maximum benefit.
  • (20) Low-density lipoprotein apheresis (LDL-apheresis) was done with either cascade filtration (DF) or dextran sulfate cellulose adsorption (DSC) in a patient with primary biliary cirrhosis who developed severe dyslipidemia associated with cholestasis and accumulation of lipoprotein-X (LP-X).

Extraction


Definition:

  • (n.) The act of extracting, or drawing out; as, the extraction of a tooth, of a bone or an arrow from the body, of a stump from earth, of a passage from a book, of an essence or tincture.
  • (n.) Derivation from a stock or family; lineage; descent; birth; the stock from which one has descended.
  • (n.) That which is extracted; extract; essence.

Example Sentences:

  • (1) The promoters of the adenovirus 2 major late gene, the mouse beta-globin gene, the mouse immunoglobulin VH gene and the LTR of the human T-lymphotropic retrovirus type I were tested for their transcription activities in cell-free extracts of four cell lines; HeLa, CESS (Epstein-Barr virus-transformed human B cell line), MT-1 (HTLV-I-infected human T cell line without viral protein synthesis), and MT-2 (HTLV-I-infected human T cell line producing viral proteins).

  • (3) Immunocompetence was also evident when the cells from thymectomized donors were first incubated with thymus extract for 1 hr and subsequently tested for reactivity.
  • (4) Consensual but rationally weak criteria devised to extract inferences of causality from such results confirm the generic inadequacy of epidemiology in this area, and are unable to provide definitive scientific support to the perceived mandate for public health action.
  • (5) The specific activities of extracts from cells grown under phototrophic and aerobic conditions were similar and not affected by the concentration of iron in the growth media.
