In 2006, a connection was made between Gadolinium-based Contrast Agents (GBCAs) administered for contrast-enhanced MRIs and Nephrogenic Systemic Fibrosis (NSF). NSF is a potentially fatal disease that has been diagnosed almost exclusively in patients with end-stage renal disease (ESRD). Prolonged excretion times and the instability of the GBCA results in the toxic gadolinium ion separating from...
In previous papers of this series the temperature-dependent Raman spectra of poly(dA).poly(dT) and poly(dA-dT).poly(dA-dT) were used to characterize structurally the melting and premelting transitions in DNAs containing consecutive A.T and alternating A.T/T.A base pairs. Here, we describe procedures for obtaining thermodynamic parameters from the Raman data. The method exploits base-specific an...
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...
The contributions of Sophya Kowalewski to the integrability theory of the equations for the heavy top extend to a larger class of Hamiltonian systems on Lie groups; this paper explains these extensions, and along the way reveals further geometric significance of her work in the theory of elliptic curves. Specifically, in this paper we shall be concerned with the solutions of the following diffe...
Introduction Cognitive and gait deficits are common symptoms in Parkinson's disease (PD). Motor-cognitive dual tasks (DTs) are used to explore the interplay between gait and cognition. However, it is unclear if DT gait performance is indicative for cognitive impairment. Therefore, the aim of this study was to investigate if cognitive deficits are reflected by DT costs of spatiotemporal gait par...
Lavender (Lavandula angustifolia Mill.) is one of the most widely grown essential oil crops in the world. Commercial extraction of lavender oil is done using steam distillation. The objective of this study was to evaluate the effect of the length of the distillation time (DT) on lavender essential oil yield and composition when extracted from dried flowers. Therefore, the following distillation...
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...
