Iodine is essential for normal development, and its deficiency can cause growth retardation and irreversible brain damage. Nowadays, the main source of iodine is iodised salt. However, in many countries discretional use of salt (cooking and table salt) is increasingly being replaced by salt from processed foods. This situation has raised concern about the risk of iodine inadequacy if the food i...

This paper carried out experimental study, through extraction and characterization of both crude and refined castor oil. Normal hexane was used as solvent for the extraction process. The oil produced was refined through degumming, neutralization and bleaching process using local adsorbent (activated clay). The characterization analysis revealed that tested parameters, which include specific gra...

BACKGROUND Iodine is the key element for thyroid hormone synthesis, and its deficiency, even moderate, is harmful in pregnancy, when needs are increased, because of its potential deleterious effects on fetal brain development. In Portugal, no recent data on iodine intake exists. The objective of this countrywide study was to analyze iodine status in pregnant Portuguese women in order to propose...

Although biological methods are used for assessing the value of thyro-active materials, chemical methods are also available to determine the thyroxine content of such substances. These methods are mainly based on the estimation of iodine as 'thyroxine iodine' (Harington & Randall, 1929; Leland & Foster, 1932; Brand & Kassell, 1939). Polarographic analysis suggests itself as a means of simplifyi...

The usefulness of the various tests of thyroid function has been evaluated over a three-year period. It is concluded that an uptake test and estimation of the serum protein-bound radioactive iodine (PB (131)I), supplemented as required by the protein-bound iodine (PBI), remain the best routine tests of thyroid function. Forty-five patients who gave discordant results on these tests over this pe...

The relationship is shown between a concentration of urinary iodine and serum thyroglobulin in population studies carried out on a general population that was randomly selected from the registry of the General Health Insurance Company (individuals aged 6-98 years, 1751 males, 2420 females). The individuals were divided into subgroups with a urinary iodine concentration of <50, 50-99, 100-199, 2...

The present unicentric, hospital based, non-interventional, cross-sectional study was undertaken to assess the iodine status of pregnant women attending the antenatal clinic at a medical college in Kolkata, India, during the different trimesters of pregnancy and to compare their iodine status with those of age-matched non-pregnant control women. Assessment of the iodine status was based on urin...

I read with interest the article by Özdeniz et al. (1), on dual-source dual-energy computed tomography (DECT) to differentiate fecal matter from neoplasm. The study was well done and was based on density measurements in iodine maps and virtual unenhanced images. I would like to add a few points to the discussion. The main advantage of DECT is material decomposition and the relative iodine conce...

Iodine is an essential element in the chemical structure of thyroid hormones. The human body requires around 150 g of iodine everyday, which works out to be a teaspoonful (5gm) over a life span of 70 years. Iodine deficiency is the most common cause of brain damage. The magnitude of IDD in India includes 167 million people at risk and goitre is being considered as important public health probl...
