Thyroid 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...

Adducin-1 moonlights at the mitotic spindle A n actin-binding protein helps shape the mitotic spindle, Chan et al. report. Researchers long thought that actin and microtubules performed different tasks during mitosis. They believed that micro tubules formed the mitotic spindle that pulls chromosomes apart, whereas actin joined with myosin to produce the contractile furrow that separates the mot...

Since the 19th century, there have been sporadic attempts to attribute the changes of aging to one or another endocrine deficit and efforts to reverse these changes by various replacement therapies. This search for a hormonal 'fountain of youth' continues today.
متن کاملThyroid 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...
