  • (17) The tryptic cores from H-2K and H-2D are regularly distinguishable from the thymus-leukemia antigens (TLA) by gel electrophoresis in one dimension.

Thyroid


Definition:

  • (a.) Shaped like an oblong shield; shield-shaped; as, the thyroid cartilage.
  • (a.) Of or pertaining to the thyroid body, thyroid cartilage, or thyroid artery; thyroideal.

Example Sentences:

  • (8) Thyroid hormones suppress transcription of the gene for the beta-subunit of thyrotropin (TSH beta).
  • (9) In conclusion, autoimmune thyroiditis in an animal model can be prevented by reducing thyroidal iodine or its metabolism and optimal effects require intervention at the embryonic stage.
  • (10) The nature of the putative autoantigen in Graves' ophthalmopathy (Go) remains an enigma but the sequence similarity between thyroglobulin (Tg) and acetylcholinesterase (ACHE) provides a rationale for epitopes which are common to the thyroid gland and the eye orbit.
