Thyroid hormones and thermogenesis.
An extensive review article on thyroid hormone published nearly 40 years ago (Barker, 1951) might have led one to suppose that little could be added to the subject of thyroid hormones and thermogenesis. However, a large number of new ideas have since emerged with respect to the mechanisms of action of thyroid hormones, although there is still considerable uncertainty as to how they function at ...
متن کاملThyroid Hormones and Mesotherapy
Thyroid hormones are the master regulator of body metabolism and growth. They act at molecular level to manipulate genes and cellular functions to balance the basic metabolic rate. They bind to superfamily of nuclear receptors that recognize discrete sequences of DNA and act as transcription factors (Renkawitz et al., 1996). At the cellular level, thyroid hormones act directly on the mitochondr...

متن کامل[Biosynthesis of thyroid hormones].
Several problems are involved in the studies on the biosynthesis of thyroid hormones : 1) How are iodine atoms incorporated into a thyroglobulin (TG) molecule ? 2) How is the matured TG molecule built up? 3) how are carbohydrates incorporated in a TG molecule? 4) How are amino acids assembled to make up TG polypeptides? 5) How is TG hydrolyzed to produce T3 and T4 ? Recent progresses concerning...
متن کاملThyroid hormones and aging.
With an increase in age, marked changes in thyroid hormone production, metabolism, and action occur. This results in an increased prevalence of (subclinical) thyroid disease in the elderly. In general, subclinical thyroid disease is associated with an increased risk of overt thyroid dysfunction and with different negative clinical parameters. In the elderly, however, it is unclear whether these...
