X-ray absorption spectra of a number of organic iodine and bromine compounds of biological relevance, as well as of a series of iodine compounds with different oxidation states, have been measured. The iodine K-edge spectra (XANES) are found to be relatively featureless but the position of the edge is found to be sensitive to formal valence (among other factors), and the edge shape to the numbe...

The research on synthesis of carbon from rice groats at various pyrolysis temperatures and its application for the recovery chromium wastewater tannery industry by varying 300, 400, 500 °C. results are analyzed in form determination yield, water content, ash iodine number. best condition with quality requirement is a temperature °C 760 mg.g-1 (iodine number). Adsorption kinetics was also carrie...

Background and objectives: Thyroid hormone exercises vital role in the event of development of central nervous system in stage of fetal life, childhood, and maintains tropic action in adulthood and also in aging. Deficiency in thyroid hormones responsible for impairment of mental performance. Inadequate iodine intake was is the major health problem. Use of iodized salt is now in vogue globally ...

The relationship between the iodine intake level of a population and the occurrence of thyroid diseases is U-shaped with an increase in risk from both low and high iodine intakes. Developmental brain disorders and endemic goiter caused by severe iodine deficiency may seriously deteriorate overall health status and economic performance of a population. Severe iodine deficiency with a median 24-h...

BACKGROUND Iodine deficiency disorders (IDDs) refer to a series of diseases caused by the human body's insufficient iodine intake. Edible salt became iodized in China in 1996, which yielded remarkable results. We have known that IDDs is associated with iodine in the human body, but it is not clear whether IDDs is related to medical resource level. METHODS We collected the number of IDDs cases...

BACKGROUND The effects of severe iodine deficiency during critical periods of brain development are well documented. There is little known about the consequences of milder forms of iodine deficiency on neurodevelopment. OBJECTIVE The objective was to determine whether supplementing mildly iodine-deficient children with iodine improves cognition. DESIGN A randomized, placebo-controlled, doub...

Iodine is a trace element essential for synthesis of the thyroid hormones, triiodothyronine and thyroxine. These hormones play a vital role in the early growth and development stages of most organs, especially the brain. The World Health Organization (WHO) has declared that, after famine, iodine deficiency is the most avoidable cause of cerebral lesions including different degrees of mental ret...

1. Denatured tobacco mosaic virus has a number of SH groups corresponding to its total sulfur content of 0.2 per cent. The SH groups were estimated by titration with ferricyanide, tetrathionate, and p-chloromercuribenzoate in guanidine hydrochloride solution and by reduction of the uric acid reagent in urea solution. 2. The SH groups of tobacco mosaic virus or their precursors can be abolished ...

OBJECTIVES To evaluate the role of iodine-131 metoiodobenzylguanidine (iodine-131 MIBG) scanning in the management of paediatric patients with neuroblastoma. SUBJECTS AND METHODS Forty-three iodine-131 MIBG scans were performed on 26 children, 18 male and 8 female, ranging in age from 8 months to 11 years. Bone scan, computed tomography (CT) images and findings of bone marrow biopsy were comp...

I t has been demonstrated by a number of workers that the active principle of the thyroid gland in the causation of amphibian metamorphosis is iodine. Recently Swingle 1 has obtained definite proof that inorganic iodine when fed to larvm of Salientia induces metamorphosis in a short time after the be#nning of the feeding. On the other hand, it has been shown by the writer 2 that the retarding i...
