PURPOSE Combretastatin A4 phosphate (CA4P) is a novel vascular targeting agent. Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) studies were performed to examine changes in parameters related to blood flow and vascular permeability in tumor and normal tissue after CA4P treatment. MATERIALS AND METHODS Changes in kinetic DCE-MRI parameters(More)
The anti-vascular effects of the tubulin binding agent, disodium combretastatin A-4 3-O-phosphate (CA-4-P), have been investigated in the rat P22 carcinosarcoma by measurements of radiolabelled iodoantipyrine uptake and dynamic contrast-enhanced MRI. The iodoantipyrine estimates of absolute tumour blood flow showed a reduction from 0.35 to 0.04 ml g(-1)(More)
In this study, we measured transfection efficiency in vitro and in vivo using the following nonviral approaches of gene delivery: injection of plasmid DNA, electroporation-assisted, liposome-enhanced, and integrin-targeted gene delivery, as well as the combination of these methods. Four histologically different tumor models were transfected with a plasmid(More)
The antivascular actions of disodium combretastatin A-4 3-O-phosphate (CA-4-P) were investigated in the rat P22 carcinosarcoma after single doses of 10 or 30 mg x kg(-1). Pharmacokinetic data showed that 10 mg x kg(-1) in the rat gave a plasma exposure similar to that achieved in the clinic. Blood flow rate to the tumor and normal tissues was measured using(More)
Hypoxia has been associated with poor local tumour control and relapse in many cancer sites, including carcinoma of the prostate. This translational study tests whether breathing carbogen gas improves the oxygenation of human prostate carcinoma xenografts in mice and in human patients with prostate cancer. A total of 23 DU145 tumour-bearing mice, 17 PC3(More)
The motivation behind every educator's dedication and hard work in the classroom is the knowledge that his or her teaching will result in students' success in life. Educators are committed to implementing twenty-first century skills; they have no question that students need such skills to be equipped for life beyond school.

The synthesis and spectroscopic properties of a series of CF(3)-labelled lanthanide(III) complexes (Ln=Gd, Tb, Dy, Ho, Er, Tm) with amide-substituted ligands based on 1,4,7,10-tetraazacyclododecane are described. The theoretical contributions of the (19)F magnetic relaxation processes in these systems are critically assessed and selected volumetric plots(More)
PURPOSE To develop and characterize a new paramagnetic contrast agent for molecular imaging by MRI. METHODS A contrast agent was developed for direct MRI detection through the paramagnetically shifted proton magnetic resonances of two chemically equivalent tert-butyl reporter groups within a dysprosium(III) complex. The complex was characterized in(More)
AIM To investigate whether a hospital-specific opportunity-based composite score (OBCS) was associated with mortality in 136,392 patients with acute myocardial infarction (AMI) using data from the Myocardial Ischaemia National Audit Project (MINAP) 2008-2009. METHODS AND RESULTS For 199 hospitals a multidimensional hospital OBCS was calculated on the(More)
OBJECTIVE To evaluate the performance of the National Institute for Health and Clinical Excellence (NICE) mini-Global Registry of Acute Coronary Events (GRACE) (MG) and adjusted mini-GRACE (AMG) risk scores. DESIGN Retrospective observational study. SETTING 215 acute hospitals in England and Wales. PATIENTS 137 084 patients discharged from hospital(More)
