Abstract:

Bioluminescence is the chemical production of light that results when a luciferase enzyme catalyzes the luminogenic oxidation of a small-molecule luciferin substrate. The numerous luciferases and luciferins nature has evolved can be used to illuminate biological processes, from in vitro assays to imaging processes in live animals. However, we can improve the utility of bioluminescence through modification of these enzymes and substrates. My thesis work focuses on developing reporters that expand the bioluminescent toolkit and improving our understanding of how bioluminescence works on a molecu

Abstract:

Firefly luciferase is ubiquitously used as a genetic reporter for the non-invasive bioluminescence imaging of small animal models. This widespread use of Firefly luciferase in vivo has been facilitated by genetic engineering producing mutants which are extremely stable at physiological conditions. In addition, the red-shifting of bioluminescence has resulted in the enhanced penetration of light emission through biological tissue. However, the use of bioluminescence in vivo is still largely limited to the tracking of single events within a model. This is due to the differential attenuation of l

Non-viral gene delivery is plagued by low transfection levels compared to viral delivery. The nuclear envelope presents a significant obstacle for non-viral vectors. A peptide-based nuclear localizing sequence has been incorporated into non-viral vectors to traverse the nuclear envelope. Here, we selected a photo-chemical method for covalently labeling the peptide onto plasmid DNA. The hypothesis of this work was to incorporate a nuclear localizing sequence into a non-viral delivery vector, demonstrate increased nuclear uptake and show a subsequent increase in transgene expression both in vitr

Abstract:

In vitro differentiation of stem cells in biocompatible scaffolds in a bioreactor is a promising method for creating functional engineered tissue replacements suitable for implantation. Basic studies have shown that mechanical, chemical, and pharmaceutical stimuli enhance biological functionality of the replacement as often defined by parameters such as cell viability, gene expression, and protein accumulation. Most of the assays to evaluate these parameters require damage or destruction of the cell-scaffold construct. Therefore, these methods are not suitable for monitoring the development

Despite the importance of molecular recognition in nearly all aspects of protein function, the determinants of specificity for enzyme-substrate and protein-protein interactions are poorly understood. The majority of these complexes involving bacterial luciferase from V. harveyi have yet to be fully characterized. Luciferase catalyzes the reaction of molecular oxygen, FMNH2 and a long-chain aliphatic aldehyde yielding FMN, the corresponding carboxylic acid and blue-green light. In vivo, luciferase is thought to obtain FMNH2 following transfer from a transiently associated oxidoreductase. To

Obesity is a major growing cause of death with no effective long-term treatment apart from surgical procedures such as Roux-en-Y gastric bypass (RYGB).

Peripheral administration of PYY3-36 suppresses appetite in rodents and man and represents a potential therapy for obesity however its effects on feeding are transient.

Moving beyond <i>in vitro</i> models, into <i>in vivo</i> models, earlier in the development process will greatly aid in the advancement of the next generation of nanomedicines. By moving to whole animal models, our understanding of these systems progresses beyond cell targeting and uptake, to developing mechanisms for how these materials will distribute through tissues and their pharmacokinetic profile.

Abstract:

For the development of the next generation of polymeric nanomedicines, it is crucial to gain a fundamental understanding of their behaviour and interactions with and within biological systems. Moving beyond in vitro models, into in vivo models, earlier in the development process will greatly aid in the advancement of the next generation of nanomedicines. By moving to whole animal models, our understanding of these systems progresses beyond cell targeting and uptake, to developing mechanisms for how these materials will distribute through tissues and their pharmacokinetic profile.

Abstract:

We investigate the possibility of extracting accurate functional information such as local blood oxygenation level using multi-wavelength photoacoustic measurements. Photoacoustic microscope is utilized to acquire images of microvasculature in smallanimal skin. Owing to endogenous optical contrast, optical spectral information obtained from spectral photoacoustic measurements are successfully inverted to yield oxygenation level in blood. Analysis of error propagation from photoacoustic measurements to inverted quantities showed minimum inversion error in the optical wavelength region of 570-60

Abstract:

The goal of this research was to demonstrate the potential of spectral CT for the discrimination of vulnerable atherosclerotic plaques. It was proposed that spectral CT has the potential to identify the presence of specific markers for vulnerable plaques: iron deposits and lipid core. A spectral micro-CT system incorporating the latest Medipix spectroscopic photon- counting detectors was commissioned for this purpose. Using spectroscopic methods developed with this system, it was possible to distinguish the presence of iron deposits and lipid core within ex vivo atherosclerotic plaques. Athero

Abstract:

The aim of this work was to develop tri-modal cell labels for tracking immune cells in vivo, particularly for longitudinal studies of immune cell therapies. Localisation and quantification of the cells is invaluable in determining the effectiveness of these treatments, so imaging agents for fluorescence, \(^1\)H MRI and \(^19\)F MRI were combined. Four combinations of agents in a robust scaffold were investigated: luminescent dyes and a \(^1\)H MRI contrast agent were trapped electrostatically in a silica matrix; luminescent dyes and proton MRI agents were bound to silica and gold nanoparticle

Abstract:

Upconversion nanoparticles (UCNPs) have been utilized for biological applications. Unlike conventional linear excitation molecules, UCNPs are excited by 980nm and emit photon in visible and near infrared region. The unique photophysical property offers superior penetration depth and lower photo-cytotoxicity. With the aid of various vectors such as target-specific peptides and photosensitizers, the UCNPs can precisely interact selectively with designated proteins (Cyclin D1 and Polo-like Kinase 1) and cancer cells so as to achieve theranostic effect. This thesis illustrated the upconversion mec
