TL;DR: These studies revealed, for the first time, the presence of the ovarian 5'-monodeiodinase system in FF capable of generating T3 (ovary-born T3) by outer ring deiodination of T4.

TL;DR: The results indicate that 131I-insulins are rapidly degraded by proteolysis to simple amino acid constituents by the liver, and confirms nor denies that reductive cleavage of interchain —S—S— bonds of insulins is an initial step in the degradation of insulin.

TL;DR: The fraction available suggests an importance of drinking water supply for population iodine Intake, although this may not be adequate to estimate population iodine intake.
Abstract: Iodine intake is important for thyroid function. Iodine content of natural waters is high in some areas and occurs bound in humic substances. Tap water is a major dietary source but bioavailability of organically bound iodine may be impaired. The objective was to assess if naturally occurring iodine bound in humic substances is bioavailable. Tap water was collected at Randers and Skagen waterworks and spot urine samples were collected from 430 long-term Randers and Skagen dwellers, who filled in a questionnaire. Tap water contained 2mg/l elemental iodine in Randers and 140mg/l iodine bound in humic substances in Skagen. Median (25; 75 percentile) urinary iodine excretion among Randers and Skagen dwellers not using iodine-containing supplements was 50 (37; 83) mg/24h and 177 (137; 219) mg/24h respectively (P,0·001). The fraction of samples with iodine below 100mg/24h was 85·0% in Randers and 6·5% in Skagen (P,0·001). Use of iodine-containing supplements increased urinary iodine by 60mg/24h (P,0·001). This decreased the number of samples with iodine below 100mg/24h to 67·3% and 5·0% respectively, but increased the number of samples with iodine above 300mg/24h to 2·4% and 16·1%. Bioavailability of iodine in humic substances in Skagen tap water was about 85%. Iodine in natural waters may be elemental or found in humic substances. The fraction available suggests an importance of drinking water supply for population iodine intake, although this may not be adequate to estimate population iodine intake.

TL;DR: In this article, the authors investigated the oxidation behavior of iodide and showed that iodide yielded two oxidation peaks P a1 and P a2 in [C 4 mim][BF 4 ], and both of them are diffusion-controlled.
