this work was aimed to evaluate and compare the performances of the solvents d2ehpa (di-(2-ethylhexyl) phosphoric acid), cyanex 272 (bis (2,4,4-trimethylpentyl) phosphinic acid), and a mixture system of d2ehpa and cyanex272 in the separation of some rare earth elements (rees) including lanthanum, gadolinium, neodymium, and dyspersym from a nitric acid solution. the results obtained showed that ...
Background: Glucose transporter (Glut), a cellular transmembrane receptor, has a key role in the metabolism of cell glucose and is also associated with various human carcinomas.Objective: In this study, we evaluated a magnetic resonance (MR) imaging contrast agent for tumor detection based on paramagnetic gadolinium oxide (Gd2O3) coated polycyclodextrin (PCD) and mod...
اگرچه (Gadolinium-diethylene triamine pentacetic acid=Gd-DTPA) به عنوان یک عامل کنتراست در تصویرگیری به روش رزنانس مغناطیسی (MRI) شناخته شده است، ولیکن افزایش اثر کنتراست آن برای غلظت های زیاد یکنواخت نیست. برای بهینه انتخاب کردن پارامترهای مناسب برای این عامل کنتراست، آزمایشات MRI بر روی نمونه های خون، سلول های سرطان پوست (Melanoma cell line)، کلراید سدیم با غلظت های مختلف Gd-DTPA و محلول های ...
Gd(2)O(3) and Gd-doped HfO(2) films were deposited on p-type silicon substrates in a reducing atmosphere. Gd 4f photoexcitation peaks at roughly 7 and 5 eV below the valence band maximum have been identified using the resonant photoemission of Gd(2)O(3) and Gd-doped HfO(2) films, respectively. In the case of Gd(2)O(3), strong hybridization with the O 2p band is demonstrated, and there is eviden...
The coexistence of Graves’ disease (GD) and inflammatory bowel disease (IBD), particularly Crohn’s disease (CD) and ulcerative colitis (UC), has not been well documented. Therefore, this report reviews the literature regarding coexisting IBD and GD. Reported cases of concomitant IBD and GD are rare; 16 cases of concomitant UC and GD and 3 cases of concomitant CD and GD were found. Among the 19 ...
