Dementors drain âpeace, hope, and happiness out of the air around them,â according to Lupin (PA10). Even before a Dementor is seen, its presence is obvious; they are surrounded by an unnatural darkness and terrible icy cold (PA5). Dementors affect even Muggles, although the Muggles canât see the foul, black creatures. They were the guards at Azkaban and made that place horrible indeed.
The thyroid gland of a healthy adult concentrates 70-80% of a total body iodine content of 15-20 mg and utilizes about 80 Î¼g of iodine daily to synthesize thyroid hormones. In contrast, chronic iodine deficiency can result in a dramatic reduction of the iodine content in the thyroid well below 1 mg (1).
Iodine is a trace mineral required by the body for the synthesis of the thyroid hormones, T4 and T3. T4 contains 4 iodine atoms and when one of the iodine atoms is stripped off of T4, it becomes T3, with 3 iodine atoms remaining.luoride has the potential to impair thyroid function and was used as a thyroid-suppressing medication for patients with hyperthyroidism. Fluoride was utilized because it was found to be effective at reducing the activity of the thyroid gland â even at doses as low as 2 mg/day.
