New Surfaces for the Control of Endothelial Cell Function: Application in the Design of Biocompatible Stents. Using dewetting of thin polymer films, the present proposal will develop new structured biocompatible surfaces with controlled chemistry and topography, which will allow the growth of a normal (non-activated) monolayer of endothelial cells. Sophisticated molecular parameters will be used to assess that endothelial cells maintain their normal quiescent phenotype.

Using dewetting of thin polymer films, the present proposal will develop new structured biocompatible surfaces with controlled chemistry and topography, which will allow the growth of a normal (non-activated) monolayer of endothelial cells. Sophisticated molecular parameters will be used to assess that endothelial cells maintain their normal quiescent phenotype. The project sets the ground work for the design of improved, more biocompatible structured stents to minimise the abnormal growth of cells on and around the stent, thereby reducing the occurrence of vascular complications. Thus this research could improve the success rate of stents implanted into patients with cardiovascular disease and reduce health costs.Read moreRead less

The roles of metal ions in glucose metabolism and the treatment of diabetes. Metal supplements, such as chromium and vanadium are consumed widely for their purported fat reduction and anti-diabetic activities. However, much is still to be learnt about the efficacy and safety of such metal ions when they are taken in supplements and whether they have an essential role in the prevention of diabetes or, in some instances, are a risk factor for cancer.

However, much is still to be learnt about the efficacy and safety of such metal ions when they are taken in supplements and whether they have an essential role in the prevention of diabetes or, in some instances, are a risk factor for cancer. The research will provide an understanding of how these metal complexes exert their anti-diabetic effects and how they can be made safer and/or more efficacious for the treatment of type 2 diabetes, which is a rapidly expanding epidemic in developed countries.

Synthesis and Applications of Antifreeze Proteins and Glycoproteins. Many cells are damaged when they are chilled below body temperatures thus limiting shelf-life for applications. For example, storage of human blood platelets is limited to 5 days at 22 degrees.

This research will produce molecules that can be used in the fields of agriculture (in vitro fertilization techniques, development of improved blood lines), aquaculture and human reproductive technologies, where ice crystal growth and freezing are damaging. This outcome will be achieved by the synthesis of molecules that mimic natural products that allow fish to survive in the icy Arctic and Arctic Oceans and study how they are able to protect cells and tissues from damage in these extreme environments.Read moreRead less

High-resolution imaging of live cells and tissue. Understanding the machinery of life and developing technologies that support life's processes requires biological and physical scientists and engineers to monitor molecular events in living systems. The aim is to take advantage of very recent developments in light microscopy to enable the non-invasive imaging of live cells and tissue at a previously unreachable level of detail. The instruments will form the nucleus of a new imaging facility. Sign ....High-resolution imaging of live cells and tissue.

Development of Pyrrolopyrimidines as Inhibitors of ATP-Binding Proteins. This project seeks to generate analogues of natural products that have been found to be active against cancer cells and tropical parasites. The new materials produced by this project will aid in the study of biochemical processes involved in diseases such as cancer and lymphatic filariasis, thus leading the way to development of these compounds as potential treatments for such diseases.
Enhanced biocatalysis in organic solvents for pharmaceutical biotransformation. Enzymes such as hydrolases play an important role in biotechnology because of their extreme versatility with respect to substrate specificity and stereoselectivity. The use of lipases as catalysts for optical isomer-specific organic reactions is often limited by unacceptably low enantioselectivities. We will investigate recombinant enzymes cloned from thermophilic lipolytic bacteria for synthetic reactions in orga ....Enhanced biocatalysis in organic solvents for pharmaceutical biotransformation. Enzymes such as hydrolases play an important role in biotechnology because of their extreme versatility with respect to substrate specificity and stereoselectivity. The use of lipases as catalysts for optical isomer-specific organic reactions is often limited by unacceptably low enantioselectivities. We will investigate recombinant enzymes cloned from thermophilic lipolytic bacteria for synthetic reactions in organic solvents, especially chiral resolution of mixtures in the production of pharmaceutical intermediates. Genetic improvement of lipase enantiospecificity and regioselectivity will be achieved using in vitro evolution by recombination and screening. The outcome will be cost-effective production superior biocatalysts with specifically enhanced regiospecific, enantioselective and hydrolytic characteristics.
