(5) In contrast, 52% of the iodine administered in the form of DIT was excreted in the urine in the same time interval.
(6) Short periods of loading do not alter deiodination of L-DIT in liver or kidney at all; but lead to significant elevation of L-T4-deiodination in liver tissue.
(7) DIT may play a central role in the regulation of energy expenditure and in the etiology of certain types of obesity.
(8) DIT and BAT are controlled by hormonal action: noradrenaline appears to be the primary activator of BAT and insulin may be required for DIT and may even activate thermogenesis.
(9) The levels of MIT, DIT, T3 and T4 in the thyroid, and T3, T4 and TSH in serum, and the amount of iodine transport and synthesis of organic iodine in thyroid were determined.
(10) Higher doses or longer periods of loading cause a significant rise of L-DIT-deiodination in liver and kidney, while the L-T4-deiodination in liver is significantly decreased and in kidney significantly elevated.
(11) The secretion of gastric acid in the peptic ulcer patients were examined by the dopamine infusion test (DIT).
(12) In rats hypothyroidized with methylthiouracil (MTU), methimazol (MMI), or radiothyroidectomy, the extent of deiodination for L-diiodotyrosine (L-DIT) and L-thyroxine (L-T4) was investigated in homogenate supernatants of liver and kidney.

(15) The carbonyl complexes were found to be efficient hepatobiliary agents and cleared more rapidly than the corresponding 99mTcN- and 99mTc(dit)-complexes.
(16) From the results of kinetic studies and RIA measurements, the fraction of circulating T4 converted to DIT was calculated to be 3.9-4.3%.
(17) While rT3 is elevated in almost all critically ill patients, the increase in DIT is indicative of severe infection.
(18) The reaction is effectively quenched by the antioxidant, 2,6-dit-butyl-4-hydroxymethyl phenol as well as by Mn+2 (10(-5)-10(-3)M).

Doit
Definition:
(n.) A small Dutch coin, worth about half a farthing; also, a similar small coin once used in Scotland; hence, any small piece of money.
(n.) A thing of small value; as, I care not a doit.
Example Sentences:
