Small globules of the follicular colloid ( Tg ) are endocytosed ( hormone ( TSH )-mediated ) and proteases in lysosomes digest iodinated thyroglobulin, releasing T3 and T4 within the thyrocyte cytoplasm.
32.
It is most commonly carried out for neuroimaging using dynamic sequential scanning of a pre-selected region of the brain during the injection of a bolus of iodinated contrast material as it travels through the vasculature.
33.
One of the products of iodide oxidation is hypoiodous acid ( HOI or OI " ) which is capable of reacting with background organic materials to generate iodinated disinfection by-products ( DBPs ) including iodoacetic acid.
34.
"' Iodotyrosine deiodinase, "'also known as "'iodotyrosine dehalogenase 1, "'is a type of deiodinase enzyme that scavenges iodide by removing it from iodinated tyrosine residues in the thyroid gland.
35.
It has many implications in the field of polymer chemistry as it can be viewed as a precursor to other polydiacetylenes by replacing iodine atoms with other side chains using organic synthesis, or as an iodinated form of the carbon allotrope carbyne.
36.
An example of the coupling of an aryl iodide to an aryl acetylene can be seen in the reaction of the iodinated alcohol and the tris ( isopropyl ) silylacetylene, which gave alkyne, an intermediate in the total synthesis of the benzindenoazepine alkaloid bulgaramine.
37.
Chloramine has become a popular disinfectant in the US, and it has been found to produce N-nitrosodimethylamine ( NDMA ), which is a possible human carcinogen, as well as highly genotoxic iodinated DBPs, such as iodoacetic acid, when iodide is present in source waters.
38.
At Sport Chalet, the Guardian Plus Purifier ( $ 69.99 ) is only 9 inches tall and weighs just 14 ounces, but it combines a . 2-micron filter to remove bacteria, iodinated resin to knock down viruses, and a carbon filter to kill the taste of the iodine and other odors.
39.
Intravenous contrast media increases diagnostic capability of Enterography MRI . Although it s better tolerated than iodinated contrast media used for CT-scan, the use of Gadolinium-based contrast agent should always be preceded by kidney function assessment, in order to reduce the risk of systemic nephrogenic sclerosis, and prophylactic protocol in case of previous allergic reactions.
40.
The same enzyme then catalyses " coupling " of one modified tyrosine with another, via a free radical-mediated reaction, and when these iodinated bicyclic molecules are released by hydrolysis of the protein, T3 and T4 are the result . hence, each Tg protein molecule ultimately yields very small amounts of thyroid hormone ( experimentally observed to be on the order of 5-6 molecules of either T4 or T3 per original molecule of Tg ).
