PURPOSE:

Published data on recombinant human thyrotropin- (rhTSH-) stimulated iodine-123 (¹²³I) diagnostic whole-body scintigraphy (DxWBS) in differentiated thyroid cancer (DTC) surveillance after initial treatment are limited. We sought to evaluate this modality's diagnostic value in this setting.

MATERIALS AND METHODS:

The optical absorbance of four ternary thin films, i.e. MgSiP2, MgGeP2, MgSiAs2, MgGeAs2 have been<br />
theoretically examined over a wide range of wavelength from 300 nm to 800 nm. The combination of<br />
first-principle electronic structure calculations and the optical matrix approach for modeling the multilayer<br />
assembly have been employed for theoretical studies. The analysis of the calculated absorbance<br />
spectra at room temperature with unpolarized light and normal incidence, revealed that MgGeAs2 with<br />

investigate the character of phase transitions in (Ba0.50,Sr0.50)TiO3 (BST50) nanodots under ideal shortcircuit<br />
(SC) and open-circuit (OC) electrical boundary conditions, and the corresponding properties are<br />
subsequently compared to the properties of bulk BST50. Our calculations indicate that the ferroelectric<br />
properties change dramatically when transitioning from 3D (bulk) to 0D (nanodot) systems under shortcircuit<br />

The sodium iodide symporter (NIS) (solute carrier family 5; SLC5A), mediates the active transport of iodine anion (I−) into thyroid follicular cells to facilitate thyroid hormone biosynthesis. Considering its fundamental role in thyroid function, our objective in this study is to explore its potential involvement in the pathogenesis of differentiated thyroid cancer (DTC).
