Carrot is a vegetable that contains many nutrients and has strong antioxidant activity as well as pro-health potential. The level of bioactive compounds is strongly connected with the production chain. The thermal treatment of food products induces several biological, physical and chemical changes. In this study, changes in the levels of iodine, total carotenoids, total polyphenols as well as t...

In 1948, Wolff and Chaikoff reported that organic binding of iodide in the thyroid was decreased when plasma iodide levels were elevated (acute Wolff-Chaikoff effect), and that adaptation or escape from the acute effect occurred in approximately 2 days, in the presence of continued high plasma iodide concentrations. We later demonstrated that the escape is attributable to a decrease in iodide t...

radioactive iodine therapy is commonly used as an adjuvant therapy in follicular and papillary thyroid carcinoma and also in the treatment of graves’ disease. the basis of which is the accumulation of radioactive iodine by the sodium-iodide symporter (nis) in the thyroid gland. expression of nis by extrathyroidal tissues including islets of pancreas has been reported. radioactive iodine uptake ...

In order to assess the Japanese dietary iodine intake, we examined the urinary iodine excretion of those on an ordinary Japanese diet chosen at random and observed whether the thyroid function might affect the amounts of urinary iodine excretion. The subjects consisted of cases of untreated hypothyroidism and chronic thyroiditis (CT) and euthyroid controls who were healthy people or had non-thy...

a general, mild and efficient protocol has been developed for the synthesis of esters and thioesters. the process has been taking place using tetra n-butylammonium iodide (tbai) as a phase-transfer catalyst and in the presence of potassium carbonate (k2co3). a wide range of esters and thioesters was prepared in high yields and suitable times by the treatment of alcohols, phenols and thiols with...

Around the world, maize cultivation is an essential part of food systems for humans and animals. Effective reactions against occurrence diseases related to deficiency elements in human diet are biofortification plant species broad importance, including maize. The enrichment with iodine difficult due poor transport this element plant’s generative organs. In marine algae, vanadium structure enzym...

OBJECTIVE A prospective randomized trial was performed to assess the usefulness of iodine supplementation in the prevention of goiter in pregnant women living in marginally iodine-deficient areas. DESIGN Eighty-six pregnant women were recruited and randomized in two groups and treated daily for up to six months after delivery with 200 microg iodide (group A) or 50 microg iodide (group B). Six...
