MR microscopy was applied for study of water mobility and concentration in tablets, used for drug delivery. The tablets made of<br />

Hydroxypropylmethylcellulose-HPMC with and without addition of a drug substance of different solubility (L-dopa and ketoprofen) were tested. Twodimensional<br />

T2 and proton density (PD) maps and their histograms were obtained. Spatial T2 and PD distributions along a tablet radius were also analyzed.<br />

Different mechanisms of tablets hydration were observed due to composition of the formulations, eg. for formulation with ketoprofen (low solubility of 0,24<br />

mg/mL) the hydrogel formation was negligible.<br />

Prolonged aluminium insults results in oxidative damage leading to hepato and nephrotoxicity in rats.1H NMR study of rat’s serum and urine have been<br />

utilized to evaluate the comparative protective effects of Bacosides and Donepezil drugs over continuous Aluminium- induced metabonomic changes.<br />

Bacosides was found to markedly attenuate the oxidative stress induced by Aluminium over long term (90 days) dose compared to Donepezil. This might be<br />

interpretated in terms of strong antioxidative property of Bacosides compared to Donepezil. The study suggests that 1H NMR metabolic profiling is an<br />

efficient method to explore the efficacy of potent molecules over metal toxicity.<br />

Tobacco dependence is the most preventable cause of death. Varenicline is a partial nicotinic receptor agonist/antagonist that is widely used as a smoking<br />

cessation aid. How varenicline helps smokers is unknown. We sought to compare the brain Blood oxygenation level dependent (BOLD) activation<br />

produced by a high dose varenicline to a lower dose varenicline in awake naïve animals, which hopes to assist in understanding the action of this partial<br />

nicotinic receptor agonist/antagonist in patients.<br />

A mutilingual dictionary of terms used in MRI and other medical physics specialties has been developed by an international network of over 200 physicists<br />

and engineers. The dictionary (available free at www.emitel2.eu) allows translation of terms between 25 languages, with extension to additional languages<br />

planned for the future. The software platform was developed to be as simple as possible without compromising content, allowing easy update and<br />

maximising longevity. The dictionary can be used as a free-standing resource or as a portal to an e-encyclopaedia of medical physics. Together, the<br />

dictionary and encyclopaedia are valuable resources for the worldwide MRI community.<br />

The purpose of this study is to develop a rodent survival model that enables fMRI at multiple time-points under sedation. In this study, 9 Sprague-Dawley<br />

rats underwent surgical placement of a long-term vascular access port. The animals were then imaged using fMRI during nerve stimulation at 1 week, 3<br />

weeks, and 5 weeks post-operatively. During imaging, all animals breathed spontaneously while intravenous sedative was administered through the port. To<br />

date, all animals have successfully been imaged at each time-point. All vascular access ports have remained patent, making these devices a viable option for<br />

longitudinal MRI studies requiring venous access.
