Glucocorticoids (cortisol in man, corticosterone in rodents) can inhibit angiogenesis, alter contractile function and reduce the inflammatory response to injury in the vascular wall. These effects are regulated by the 11beta-hydroxysteroid dehydrogenases (11HSDs) which inter-convert active glucocorticoids and their inactive 11-keto metabolites (cortisone; 11-dehydrocorticosterone) within target tissues. 11HSD2 is a unidirectional, exclusive dehydrogenase which inactivates gluc...

Background: Hypothyroidism may profoundly alter mental function and influence mood and cognition, but the neural correlates of these impairments and of thyroid hormone treatment are not well understood.Methods: We prospectively studied 24 subjects, 14 previously untreated newly diagnosed hypothyroid patients (age 42±12 yrs; 11 female, 3 men) and 10 euthyroid control subjects (41±12 yrs).
