BACKGROUND AND PURPOSE While there have been recent reports of brain retention of gadolinium following gadolinium-based contrast agent administration in adults, a retrospective series of pediatric patients has not previously been reported, to our knowledge. We investigated the relationship between the number of prior gadolinium-based contrast agent doses and increasing T1 signal in the dentate ...

Purified inside-out photosystem II vesicles with retained capacity for oxygen evolution and a simple polypeptide composition were found to be more sensitive to washing with tris(hydroxymethyl)aminomethane (Tris) at alkaline pH than right-side out thylakoids. This suggests that the thylakoid membrane limits the penetration of the active unprotonated form of Tris. The inhibition of photosynthetic...

Nephrogenic systemic fibrosis is a progressive, potentially fatal multiorgan system fibrosing disease related to exposure of patients with renal failure to the gadolinium-based contrast agents used in magnetic resonance imaging. Because of this relationship between nephrogenic systemic fibrosis and gadolinium-based contrast agents, the U.S. Food and Drug Administration currently warns against u...

The variation of the size of the capping scaffold which connects the hydroxypyridonate (HOPO) binding units in a series of tripodal chelators for gadolinium (Gd) complexes has been investigated. A new analogue of TREN-1-Me-3,2-HOPO (1) (TREN = tri(ethylamine)amine) was synthesized: TREN-Gly-1-Me-3,2-HOPO (2) features a glycine spacer between the TREN cap and HOPO binding unit. TRPN-1-Me-3,2-HOP...

Tris complexes of Ln3+ ions (Ln = La, Ce, Pr) with triphenyl-substituted cyclopentadienyl ligands were studied by optical spectroscopy. Emission both 5d - 4f and transitions was observed for Pr3+ complex. It found that the strength crystal field formed in tris is comparable to case sulfides, as a result, red luminescence Ce3+ compound. The quantum yield photoluminescence 20% latter.

We report the thermal behavior of gadolinium foils to be used in magneto thermoelectric generator cells. Magneto thermoelectric generator cell technology exploits the ferromagnetic phase transition of gadolinium to drive the movement of a diaphragm ‘shuttle’ whose mechanical energy is converted to electrical form and which enhances heat transfer through both conduction and convection. Efficient...

The imine podands tris[(2-nitrobenzylidene)aminoethyl]amine and tris[(2-nitrobenzylidene)aminopropyl]amine both stabilize copper(I), forming {tris[(2-nitrobenzylidene)aminoethyl]amine-kappa4N}copper(I) perchlorate acetonitrile disolvate, [Cu(C27H27N7O6)]ClO4.2CH3CN, (II), and {tris[(2-nitrobenzylidene)aminopropyl]amine-kappa4N}copper(I) perchlorate, [Cu(C30H33N7O6)]ClO4, (VI), respectively. The...
