Structure of Polyvinylpyrrolidone-Iodine (Povidone-Iodine)
Journal of Pharmaceutical Sciences, 1979Hydrogen triiodide adducts were prepared from N,N-dimethylacetamide, N-alkylpyrrolidone derivatives, and polyvinylpyrrolidone, and their structures were investigated by IR spectra and X-ray structure analyses and compared with the structure of povidone-iodine USP.

FOR the purposes of another investigation, it has been found necessary to devise a method of iodinating the tyrosine side-chains of keratin exclusively and completely. With aqueous solutions of iodine (0.1 N), no more than 75 per cent of the tyrosine of wool was iodinated under the best conditions used (64 hr. at 22.2° C. and pH 9).

Thyroid, 2001
Hormonal changes and metabolic demands during pregnancy result in profound alterations in the biochemical parameters of thyroid function. For thyroid economy, the main events occurring during pregnancy are a marked increase in serum thyroxine-binding globulin levels; a marginal decrease in free hormone concentrations (in iodine-sufficient areas) that ...

To the Editor:— In a case report on the treatment of chronic vaginitis with phenylmercuric nitrate (The Journal, January 19, p. 212), the patient described by Dr. Frederick W. Hitchings developed an indurated pustular acne of the face and neck after treatment was instituted for the vaginitis.

Abstract Neither maximal nor submaximal iodination of cobrotoxin, a neurotoxic protein isolated from the venom of the Taiwan cobra ( Naja naja atra ) with ICl at pH 9.0, caused any loss of lethality or antigenicity. Only tyrosine residues in cobrotoxin were iodinated.

Endocrine Reviews, 2009 Abstract Iodine deficiency has multiple adverse effects in humans, termed iodine deficiency disorders, due to inadequate thyroid hormone production. Globally, it is estimated that 2 billion individuals have an insufficient iodine intake, and South Asia and sub-Saharan Africa are particularly affected.

ABSTRACT Sheep, bovine, mouse, dog and human thyroids incorporate 35–55% (41.5%, 45.9%, 34.4%, 55.4% and 41.1%, respectively) of total lipid radiodine in an unidentified polar thyrolipid fraction moving between phosphatidyl ethanolamine and phosphatidic acid on silica gel G thin layer chromatography in a solvent system CHCl3:MeOH:H2O (80:25:3).

Activation Analysis of Paper Chromatograms for Iodine (Iodine-127→Iodine-128)
Nature, 1963Procedures for the activation analysis of paper chromatograms for the I/ sup 127/ and up to st r I/sup 128/ reaction are discussed. Sodium24 radioactivity induced in the paper was eliminated by distillation. (C.H.)

Several mechanisms are involved in the maintenance of normal thyroid hormone secretion, even when iodine intake exceeds physiologic needs by a factor of 100. The sodium-iodide symporter system contributes most to this stability. Faced with an iodine excess, it throttles the transport of iodide into the thyroid cells, the rate-limiting step of hormone ...
