Gadolinium can be used to perform diskography in patients with a documented allergy to iodinated contrast material. MR images can be obtained in multiple planes with excellent delineation of disk architecture. Dilute gadolinium leaves the disk space within a few days of injection.

The synthesis of SmCl3(THF)3 from SmCl3.6H2O is described. The reaction of SmCl3(THF)3 with NaBH4 in dry THF gave white microcrystalline tris (tetrahydroborato) tris (tetrahydrofuran) samarium (III), Sm(BH4)3(THF)3. The vibrational and magnetic properties of Sm(BH4)3...

PURPOSE Although glaucoma treatments alter aqueous humor (AH) dynamics to lower intraocular pressure, the regulatory mechanisms of AH circulation and their contributions to the pathogenesis of ocular hypertension and glaucoma remain unclear. We hypothesized that gadolinium-enhanced magnetic resonance imaging (Gd-MRI) can visualize and assess AH dynamics upon sustained intraocular pressure eleva...

Pancreatic carcinoma ranks among the most lethal of human cancers. Besides late detection, other factors contribute to its lethality, including a high degree of chemoresistance, invasion, and distant metastases. Currently, the mainstay of therapy involves resection of local disease in a minority of patients (Whipple procedure) and systemic gemcitabine. While systemic chemotherapy has some benef...

OBJECTIVE The potential of NaHCO3 versus human serum to induce germ tube formation in Candida albicans was investigated. SPECIMENS A total of 100 isolates were obtained from oral swabs of patients presenting with thrush. Approval for the study was granted by the Joint Research Ethics Committee (JREC/23/08). METHOD Confirmed C. albicans isolates by routine methods were tested for germ tube i...

We evaluated the incidence of contrast-induced nephropathy (CIN) in patients exposed to gadolinium for diagnostic or therapeutic procedures. Background: CIN with iodinated contrast agents is a leading cause of acute renal failure. Gadolinium is often used as an alternative to iodinated contrast in patients at increased risk of CIN. The safety of gadolinium in patients at increased risk of CIN h...

BACKGROUND AND PURPOSE Gadolinium-based contrast agents have been associated with lasting high T1-weighted signal intensity in the dentate nucleus and globus pallidus, with histopathologically confirmed gadolinium retention. We aimed to longitudinally investigate the relationship of multiple gadolinium-based contrast agent administrations to the Signal Intensity Index in the dentate nucleus and...

This study aims to investigate whether different player-matching mechanisms in educational multi-player online games (MOGs) can affect students’ learning performance, enjoyment perception and gaming behaviors. Based on the multi-player quiz game, TRIS-Q, developed by Tsai, Tsai and Lin (2015) using a free player-matching (FPM) mechanism, the same game, but incorporating an automatic player-matc...

   In the present work, Gadolinium Doped ceria (GDC) based solid electrolyte was successfully synthesized through wet chemical method to operate at intermediate temperature (500–700°C) for SOFCs. DSC study revealed the formation of GDC phase at 900°C during calcination. The crystal structure of GDC was identified as cubic fluorite phase and the crystallite size was found to be around 23 nm....

Several MRI contrast agents (CAs) are used in medical diagnosis that gadolinium (Gd3+) is the most widely used as contrast agents. Unfortunately, its toxicity is due to its inefficiency. In this review, we discuss about the ability of SPIONs in MRI and application in Multiple Sclerosis diagnosis. Superparamagnetic iron oxide nanoparticles (SPIONs) such as magnetite nanoparticles are used as goo...
