A readily and rapidly accessible triazine dendrimer was manipulated in four steps with 23% overall yield to give a construct displaying four maleimide groups and DOTA. The maleimide groups of the dendrimer are sensitive to hydrolysis under basic conditions. The addition of up to four molecules of water can be observed via mass spectrometry and HPLC. The evolution in the alkene region of the ¹H-...

OBJECTIVE Gadolinium neutron capture therapy (GdNCT) is a potential treatment for malignant tumors based on two steps: (1) injection of a tumor-specific (157)Gd compound; (2) tumor irradiation with thermal neutrons. The GdNC reaction can induce cell death provided that Gd is proximate to DNA. Here, we studied the nuclear uptake of Gd by glioblastoma (GBM) tumor cells after treatment with two Gd...

This present study has been described the synthesis, characterization and antibacterial activity of gadolinium doped cerium oxide nanoparticles. The nanoparticles were prepared by hydrothermal method with various concentrations of gadolinium ranges from 2 mol% to 8 mol%. The X-ray diffraction (XRD) pattern revealed the face-centered cubic structure with crystalline size of 58.3 nm to 57.4 nm wi...

Introduction: The intravenous (IV) administration of Gadolinium is routinely used in both human and animal imaging for the diagnosis of lesions that compromise the blood-brain barrier (BBB). Although it is relatively trivial in humans and larger animals, gaining IV access in the mouse turns out to be challenging (1). Mouse IV injections are most commonly administered via one of the two tail vei...

Mechanosensitive cation channels (MSC) are ubiquitous in eukaryotic cell types. However, the physiological functions of MSC in several tissues remain in question. In this study we have investigated the role of MSC in skeletal myogenesis. Treatment of C2C12 myoblasts with gadolinium ions (MSC blocker) inhibited myotube formation and the myogenic index in differentiation medium (DM). The enzymati...

BACKGROUND Cardiac involvement is common in amyloidosis and associated with a variably adverse outcome. We have previously shown that cardiovascular magnetic resonance (CMR) can assess deposition of amyloid protein in the myocardial interstitium. In this study we assessed the prognostic value of late gadolinium enhancement (LGE) and gadolinium kinetics in cardiac amyloidosis in a prospective lo...

Herein, we fabricated efficient MR imaging probes by incorporating gadolinium oxide nanoparticles (Gd2O3) and gadolinium hybrid nanoparticles (GH) within RBCs. The Gd2O3 and GH encapsulated in the RBCs exhibited high relaxation rates and revealed high sensitivity for T1 MR imaging.

BACKGROUND AND PURPOSE DTI is an MR imaging measure of brain tissue integrity and provides an attractive metric for use in neuroprotection clinical trials. The purpose of our study was to use DTI to evaluate the longitudinal changes in brain tissue integrity in a group of patients with MS. MATERIALS AND METHODS Twenty-one patients with MS starting natalizumab were imaged serially for 12 month...

OBJECTIVE This study was designed to determine the optimal mixture ratio of gadolinium and iodinated contrast agent for simultaneous direct MR arthrography and CT arthrography. MATERIALS AND METHODS An in vitro study was performed utilizing mixtures of gadolinium at six different concentrations (0.625, 1.25, 2.5, 5.0, 10 and 20 mmol/L) and iodinated contrast agent at seven different concentra...
