Vandetanib-Eluting Beads for the Treatment of Liver Tumours
VANDETANIB-ELUTING BEADS FOR THE TREATMENT OF LIVER TUMOURS ALICE HAGAN A thesis submitted in partial fulfilment of the requirements for the University of Brighton for the degree of Doctor of Philosophy June 2018 ABSTRACT Drug-eluting bead trans-arterial chemo-embolisation (DEB-TACE) is a minimally invasive interventional treatment for intermediate stage hepatocellular carcinoma (HCC). Drug loaded microspheres, such as DC Bead™ (Biocompatibles UK Ltd) are selectively delivered via catheterisation of the hepatic artery into tumour vasculature. The purpose of DEB-TACE is to physically embolise tumour-feeding vessels, starving the tumour of oxygen and nutrients, whilst releasing drug in a controlled manner. Due to the reduced systemic drug exposure, toxicity is greatly reduced. Embolisation-induced ischaemia is intended to cause tumour necrosis, however surviving hypoxic cells are known to activate hypoxia inducible factor (HIF-1) which leads to the upregulation of several pro-survival and pro-angiogenic pathways. This can lead to tumour revascularisation, recurrence and poor treatment outcomes, providing a rationale for combining anti-angiogenic agents with TACE treatment. Local delivery of these agents via DEBs could provide sustained targeted therapy in combination with embolisation, reducing systemic exposure and therefore toxicity associated with these drugs. This thesis describes for the first time the loading of the DEB DC Bead and the radiopaque DC Bead LUMI™ with the tyrosine kinase inhibitor vandetanib. Vandetanib selectively inhibits vascular endothelial growth factor receptor 2 (VEGFR2) and epidermal growth factor receptor (EGFR), two signalling receptors involved in angiogenesis and HCC pathogenesis. Physicochemical properties of vandetanib loaded beads such as maximum loading capacity, effect on size, radiopacity and drug distribution were evaluated using various analytical techniques. -

DIRECT ANALYSIS OF HOPS BY LEAF SPRAY AND PAPER SPRAY MASS SPECTROMETRY Kari Blain, M.S. Western Michigan University, 2012 The objective of this research is to develop a new and innovative method of hops analysis, which is much faster than standard testing methods, as well as reduce the amount of consumables and solvent used. A detailed discussion on the development of an ambient ionization mass spectrometry method called paper spray (PS-MS) and leaf spray (LS-MS) mass spectrometry will be presented. This research investigates the use of PS-MS and LS-MS techniques to determine the α- and β- acids present in hops. PS-MS and LS-MS provide a fast way to analyze hops samples by delivering data as rapidly as a UV-Vis measurement while providing information similar to lengthy liquid chromatographic separations. The preliminary results shown here indicate that PS-MS could be used to determine cohumulone and α/β ratios. -

So far, obtention of prenylflavonoids have been done by chemical synthesis or extraction with organic solvents, with no described methods for the isolation of IX, which has been reported to have anti-inflammatory properties. In this study, pressurized hot water extraction (PHWE) it is shown not only as effective method to extract some prenylflavonoids but to selectively change the relative amount of them, favoring the extraction of IX against XN. Thus, pressurized water extraction at 150ºC showed a high selectivity towards IX, being proposed as a method to enrich natural hop´s extracts in IX. On the other hand, the extracts thus obtained were chemically characterized and evaluated for their anti-inflammatory activity, which was higher than the expected by its content in IX.
