TL;DR: A physiological, thyromimetic role of 3,5-T2, possibly stimulating mitochondrial respiratory chain activity may be one factor involved in maintaining clinical euthyroidism in patients with reduced serum levels of T3 during nonthyroidal illness.

TL;DR: It is shown that even mild and very brief stress can induce marked increases in T3 concentrations specifically in brain but not in liver or blood, contrary to common opinion, thyroid hormones may play an important physiological role in stress reactions, at least in tissues that contain type II 5′‐iodothyronine deiodinase, such as brain and pituitary.

TL;DR: The effects of lithium (LI) and carbamazepine (CBM) on thyroid hormone metabolism were investigated in 11 regions of the brain and three peripheral tissues in rats decapitated at three different times of day, with results comparable with those seen in the prophylactic treatment of affective disorders.

TL;DR: In this paper, the authors describe the development of a highly sensitive, accurate, and reproducible RIA for the measurement of 3,3'-diiodothyronine (T 2 ) in human serum and brain tissue.

TL;DR: The results show that, contrary to expectation, a low T3 syndrome in NTI is not always associated with low serum concentrations of 3,3'-T2 and, in healthy controls, 2 different forms of acute stress significantly increased serum levels of T4 and T3, but did not affect those of 2,4-T1 or 3,5-T2.
