Clinical Endocrinology, 1973
After 20 years in the wilderness, 3,5,3′‐triiodo‐l‐thyronine (T3) has come back home, for it is exactly 20 years since Gross & Pitt‐Rivers (1952) first drew attention to its presence in human serum. A few years later Pitt‐Rivers et al. (1955) demonstrated its formation from thyroxine (T4) given to patients with athyreotic myxoedema, and in 1957 ...

Abstract The radioactive T 3 uptake test is a relatively simple laboratory procedure which indirectly measures circulating T 3 , the active fraction of the thyroid hormone. The present study applies this test to the three trimesters of pregnancy, the postpartum period, and to inevitable and incomplete abortions.

PROPRANOLOL, TRIIODOTHYRONINE, REVERSE TRIIODOTHYRONINE AND THYROID DISEASE
Clinical Endocrinology, 1979SUMMARYPropranolol alone was given to sixteen hyperthyroid, and concomitantly with thyroxine therapy to ten hypothyroid patients. Following treatment of the hyperthyroid group for 1–2 weeks there was a significant decrease in serum triiodothyronine (T3) which correlated with the plasma propranolol steady state concentration.

Excerpt To the editor: Shenkman and associates (1) remind us that an elevated serum triiodothyronine (T3) concentration need not mean hyperthyroidism.

Clinica Chimica Acta, 1977
The possibility that lithium affects the conversion of thyroxine to 3,5,3"-triiodothyronine and 3,3',5'-triiodothyronine (reverse triiodothyronine) was studied by measurement of the serum concentractions of these parameters in five patients during the first week of lithium therapy. In three patients there was a decrease in serum thyroxine concentration

Evidence That Triiodothyronine and Reverse Triiodothyronine Are Sequentially Deiodinated in Man*
The Journal of Clinical Endocrinology & Metabolism, 1978We have demonstrated that in patients given a single iv injection of T3, rT3, or, to a lesser extent, T4, all labeled with 125I in the outer or phenolic ring, chromatography of serum on columns of Sephadex G-25 superfine revealed the presence of a labeled material, separate from the administered hormone and from both iodide and iodoprotein.

Reverse triiodothyronine in the chicken
Life Sciences, 1977Abstract Reverse triiodothyronine (rT 3 ) which is apparently a product of 5-monodeiodination of thyroxine (T 4 ) at the periphery, was measured in 199 chickens of various strains. rT 3 was virtually absent in young birds (less than 1 week to 8 weeks of age) in marked contrast to the elevated rT 3 levels found in human and other mammalian neonates.

Presence of Triiodothyronine in Fowl
Nature, 1958THE observation of an unknown iodinated compound as a regular constituent of plasma and thyroid tissue of mice and rats1–3 led to the discovery of 3-5 : 3′-triiodo-L-thyronine4–7. It has been established that triiodothyronine possesses all the thyroid hormone qualities of thyroxine when tested in a large number of species8 and is more potent than ...

The triiodothyronine suppression test
The American Journal of Medicine, 1967Abstract The results of the triiodothyronine suppression test, as performed in one hundred fifty-five patients with suspect thyroid dysfunction, are recorded. The clinical utility of this procedure as an adjunct to the laboratory diagnosis of hyperthyroidism is confirmed. The results of the present study support the validity of the criteria for normal

The Triiodothyronine Mitochondrial Pathway
1999Numerous data show that mitochondrial activity is hormonally regulated. Besides the influence of α-agonists, glucagon and vasopressin, several studies show that glucocorticoid, thyroid hormone, vitamin D3 and peroxisome proliferators stimulate the activity of this organelle.
