Type 1 deiodinase activity and generation of triiodothyronine (T3) in prostate of sexually active rats.

30 Oct 2009 BACKGROUND: Thyroxine (T(4)) and triiodothyronine (T(3)) are involved in the development and function of the male reproductive system. The type 1 deiodinase enzyme (D1) plays a major role in the intracellular conversion of T(4) to the active form, ... Read more...

The influence of thyroid hormones on periodontitis-related bone loss and tooth-supporting alveolar bone: a histological study in rats.

20 Oct 2009 BACKGROUND AND OBJECTIVE: Recent studies have pointed to potentially periodontal risk indicators, however no information is available on the impact of changes in thyroid hormone levels on the progression of periodontitis and on the quality of ... Read more...

Regular aerobic exercise training improves endothelium-dependent arterial dilation in patients with subclinical hypothyroidism.

6 Sep 2009 OBJECTIVE: Impairment of flow-mediated endothelium-dependent arterial dilation (FMD) exists in patients with subclinical hypothyroidism (sHT). Several studies showed that exercise training can improve FMD in patients with type 1 and type 2 diabetes. ... Read more...

Technical information about 'Thyroxine'

Definition: The major hormone derived from the thyroid gland. Thyroxine is synthesized via the iodination of tyrosines (MONOIODOTYROSINE) and the coupling of iodotyrosines (DIIODOTYROSINE) in the THYROGLOBULIN. Thyroxine is released from thyroglobulin by proteolysis and secreted into the blood. Thyroxine is peripherally deiodinated to form TRIIODOTHYRONINE which exerts a broad spectrum of stimulatory effects on cell metabolism.
