The Du Bois and Du Bois body surface area (BSA) equation is used widely to normalise physiological parameters. However, that only nine subjects were used in its derivation does not appear to be well known and does not justify its ubiquitous application. Furthermore, the derivation appears to be hampered by a lack of modern statistical methods and the(More)
Stem cell transplantation for regenerative medicine has made significant progress in various injury models, with the development of modalities to track stem cell fate and migration post-transplantation being currently pursued rigorously. Magnetic resonance imaging (MRI) allows serial high-resolution in vivo detection of transplanted stem cells labeled with(More)
Bifunctional superparamagnetic magnetite/poly(dl-lactic acid-co-alpha,beta-malic acid) composite nanoparticles (PLMA-MNPs) detectable by both magnetic resonance imaging (MRI) and fluorescence microscopy were synthesized by coating Fe(3)O(4) nanoparticles with biodegradable poly(dl-lactic acid-co-alpha,beta-malic acid) copolymer (PLMA) with covalently bound(More)
To date, few studies have examined the functional connectivity of brain regions involved in complex executive function tasks, such as cognitive set-shifting. In this study, eighteen healthy volunteers performed a cognitive set-shifting task modified from the Wisconsin card sort test while undergoing functional magnetic resonance imaging. These modifications(More)
PURPOSE Selective internal radiotherapy (SIRT) with yttrium-90 ((90)Y) resin microspheres can improve the clinical outcomes for selected patients with inoperable liver cancer. This technique involves intra-arterial delivery of β-emitting microspheres into hepatocellular carcinomas or liver metastases while sparing uninvolved structures. Its unique mode of(More)
It is imperative that users of voxel-based morphometry (VBM) be aware of its reproducibility and the factors which influence results. We assessed the reproducibility of a VBM software package (SPM5) in measuring gray matter (GM) and white matter (WM) volumes from at least two consecutive 3D T1-weighted studies in 64 subjects. Factors investigated were the(More)
Ligand-mediated magnetic resonance (MR) contrast agents would be highly desirable for cancer diagnosis. In the present study, nanoparticles of Fe₃O₄ core with fluorescent SiO₂ shell were synthesized and grafted with hyperbranched polyglycerol (HPG-grafted Fe₃O₄@SiO₂ nanoparticles). These nanoparticles have a hydrodynamic diameter of 47.0 ± 4.0 nm, and are(More)
AIMS Superparamagnetic magnetite nanoparticles have been under intensive investigation in nanomedicine. However, it is still a challenge to synthesize high-quality water-stable magnetite nanoparticles for better magnetic performance and less side effects in medical MRI and nanothermotherapy. MATERIALS & METHODS We successfully synthesized hydrophilic(More)
Magnetic resonance imaging (MRI) is emerging as a powerful tool for in vivo noninvasive tracking of magnetically labeled stem cells. In this work, we present an efficient cell-labeling approach using (carboxymethyl)chitosan-modified superparamagnetic iron oxide nanoparticles (CMCS-SPIONs) as contrast agent in MRI. The CMCS-SPIONs were prepared by(More)
