  • thyroid hormones
  • In the last 30 years, the recognition of TSHomas has been facilitated by the routine use of ultrasensitive TSH immunometric assays, i.e., methods clearly able to distinguish between TSH concentration in normal controls and undetectable TSH levels in hyperthyroid patients, as well as by the direct measurement of circulating free thyroid hormones (FT4 and FT3). (springer.com)
  • In addition, hCG shows some cross-reactivity to the TSH receptor and therefore can stimulate production of thyroid hormones. (wikipedia.org)
  • This is also the mechanism of trophoblastic tumors increasing the production of thyroid hormones. (wikipedia.org)
  • stimulates
  • In the male, where LH has also been called Interstitial Cell-Stimulating Hormone (ICSH), it stimulates Leydig cell production of testosterone. (genetex.com)
  • TSH (with a half life of about an hour) stimulates the thyroid gland to secrete the hormone thyroxine (T4), which has only a slight effect on metabolism. (wikipedia.org)
  • T4 is converted to triiodothyronine (T3), which is the active hormone that stimulates metabolism. (wikipedia.org)
  • chains
  • The alpha chains are highly conserved proteins of about 100 amino acid residues which contain ten conserved cysteines all involved in disulfide bonds, as shown in the following schematic representation. (omicsgroup.org)
  • responsible
  • Just one year later, Lembeck identified serotonin in an ileal carcinoid and confirmed it as the major hormone responsible for the carcinoid syndrome [ 7 ]. (pubmedcentralcanada.ca)
  • The α subunit is thought to be the effector region responsible for stimulation of adenylate cyclase (involved the generation of cAMP). (wikipedia.org)
  • similar
  • As similar biochemical picture is found in patients with thyroid hormone resistance (RTH), a differential diagnosis between the two disorders must be performed. (springer.com)
  • Control
  • Gonadotropins are released under the control of gonadotropin-releasing hormone (GnRH) from the arcuate nucleus and preoptic area of the hypothalamus . (omicsgroup.org)
