One of the key components to the commercial success of a biological control agent for plant pathogens is formulation. Formulation of biocontrol agents can be used to: stabilize the organisms during production, distribution and storage; aid in the han

Iron oxide nanoparticles, with monocrystalline cores (generally magnetite or maghemite) and coated with organic polymer to increase chemical stability and solubility, have generated widespread interest as negative contrast (susceptibility) agents for

The advantages of incorporating spectroscopic information into magnetic resonance imaging (MRI) data sets were demonstrated by Dixon (1) and later by others (2,3). This early work focused on imaging water and fat signals with low spectral resolution

A preparation of monocrystalline iron oxide nanoparticles with an oxidized starch coating, currently in clinical trials (NC100150 Injection; CLARISCAN), was characterized by magnetization measurements, relaxometry, and photon correlation spectroscopy

The linewidth of the 1H NMR signal (7.05 T) of human whole blood titrated with a superparamagnetic contrast agent (NC100150 injection) was evaluated at different blood oxygen tensions. In deoxygenated blood and low contrast agent concentrations, NC10

For gadolinium chelates, we determined that there is a linear correlation between calculated solvent-accessible surface area and q-value, the number of rapidly exchanging water molecules directly bound to the gadolinium ion. A calibration curve was d

We have synthesized and evaluated five series of polymeric gadolinium chelates which are of interest as potential MRI blood pool contrast agents. The polymers were designed so that important physical properties including molecular weight, relaxivity,

Gadolinium and dysprosium diethylenetriamine pentaacetic acid-labeled starch microparticles (Gd-DTPA-SP and Dy-DTPA-SP) were investigated as model liver contrast agents. The liver contrast efficacy of particles with low and high metal contents was co

RATIONALE AND OBJECTIVES For use as magnetic resonance imaging reference standards, the optimal set of phantoms should cover a wide range of T1 values, with each phantom having a T1 that is stable over time and is independent of temperature and magne
