Unlike the Wolff–Chaikoff effect, the Plummer effect does not prevent the thyroid from taking up radioactive iodine, e.g. in the case of nuclear emergencies.Therefore, "plummering" with high-dose iodine is only effective in a short time window after the release of radionuclides. [9]
Selenium is a nutrient that is naturally present in many foods, added to others and is also available as a dietary supplement in pill, powder and liquid form, explains Perri Halperin, a ...
Selenium is a cofactor for the three thyroid hormone deiodinases, helping activate and then deactivate various thyroid hormones and their metabolites. Isolated selenium deficiency is now being investigated for its role in the induction of autoimmune reactions in the thyroid gland in Hashimoto's disease . [ 162 ]
Iodine deficiency is a lack of the trace element iodine, an essential nutrient in the diet.It may result in metabolic problems such as goiter, sometimes as an endemic goiter as well as congenital iodine deficiency syndrome due to untreated congenital hypothyroidism, which results in developmental delays and other health problems.
Congenital iodine deficiency has been almost eliminated in developed countries through iodine supplementation of food and by newborn screening using a blood test for thyroid function. [5] Treatment consists of lifelong administration of thyroxine (T4). Thyroxine must be dosed as tablets only, even to newborns, as the liquid oral suspensions and ...
Inactivation of thyroid hormones occurs by removal of an iodine atom on the inner ring, which converts thyroxine to the inactive reverse triiodothyronine (rT 3), or which converts the active triiodothyronine to diiodothyronine (T 2). The major part of thyroxine deiodination occurs within the cells. Deiodinase 2 activity can be regulated by ...
Guidelines recommend the administration of inorganic iodide (potassium iodide or Lugol's iodine [6] [21]) to reduce the synthesis and release of thyroid hormone. In high dosage, iodine may reduce the synthesis of thyroid hormone via the Wolff–Chaikoff effect and its release via the Plummer effect. [5]
Selenium deficiency occurs when an organism lacks the required levels of selenium, a critical nutrient in many species.Deficiency, although relatively rare in healthy well-nourished individuals, [1] can have significant negative results, [2] affecting the health of the heart and the nervous system; contributing to depression, anxiety, and dementia; and interfering with reproduction and gestation.
